DETAILED DESCRIPTION OF THE INVENTION In a knitting machine, information such as a knitting pattern representing a pattern to be knitted, which has been recorded on a predetermined recording medium such as a card, is converted into electrical signals by scanning with a scanning member. Regarding the organization information reading method that reads as
The purpose of this is to be able to automatically transport the recording medium and run the scanning member in conjunction with the travel of the carriage, thereby reading information on the recording medium and performing needle selection operations based on the reading of information on the recording medium itself. An organization that can perform the above-mentioned reading very efficiently, and also allows the above-mentioned automatic transfer of the recording medium and automatic movement of the scanning member to be carried out during the extra travel of the carriage, thereby enabling the above-mentioned reading to be carried out efficiently. A second object of the present invention is to provide an organization information reading method that, in addition to the above, can perform the above reading even more efficiently.

The present invention will be explained in detail below using illustrated embodiments applied to a home-use hand knitting machine.

First, the overall outline of a hand knitting machine to which the present invention is applied will be explained with reference to FIG. 1. A knitting machine Hx having a needle bed a reading device A equipped with a scanning member (not shown in FIG. 1) that optically scans recorded information;
In addition to this reading device A, manual operations used to manually operate various mechanisms to be described later are provided on the operation panel 2, and a control box B is equipped with various electrical and electronic circuits to be described later. It is installed behind the needle bed X, and
On the needle bed
, 3r are mounted at arbitrary positions, and on the back side of the base plate 4 of the carriage Y that runs on the needle bed In response to electrical signals obtained by scanning the knitting pattern, the rows of knitting needles on the needle bed A pair of knitting needle selection mechanisms are arranged at a predetermined length apart on the left and right sides.

The reading device A has a scanning member mounted on a carriage Y.
(More specifically, when the carriage Y is applied to the switch activation piece 31 or 3r)), the information recorded on the card 1 is automatically scanned horizontally and in a straight line. It is designed to output an electrical signal, and the subsequent processing of the electrical signal is performed by an electronic configuration, and furthermore, the power is supplied to the electrical components of the pair of left and right knitting needle sorting mechanisms. For example, the tension member 5 that applies tension to the knitting yarn is hooked by the cord 6 passed, and by reciprocating the carriage Y to the point beyond both left and right sides of the switch activation pieces 31 and 3r, the switch activation pieces 31 and 3r are tightened. Only the knitting needles within the spacing range of 31,3r are subjected to an effective sorting action (with the exception of those within this range which are in a rest position and are not subjected to any sorting action).

First, let's talk about the mechanical configuration of the reading device A.
This will be explained in detail with reference to FIG.

The entire reading device A is mounted on a frame 7 further behind the standing wall X1 at the rear end of the needle bed To explain the mechanism for transferring this, endless sprocket bells h8# and 8r, which are feeding members, are mounted on the left and right sides of the frame 7 so as to be able to circulate.

The sprocket belts 87, 8r have sprockets 8' projecting from the outer circumferential surface at a constant interval to fit into the left and right perforations 1' of the knitting program card 1, and these left and right sprocket belts 81, 8r and
By inserting the card 1 between the card guide plate 9, which has a U-shaped cross section and is arranged below the perforation 1', and fitting the perforation 1' to the sprocket 8', the sprocket The belts 81, 8r are
The card 1 can be supported in a U-shaped bent state, and in this supported state, the card 1 can be moved in a circular manner by the transfer drive mechanism a installed on the right side of the frame 7, so that the card 1 can be placed in the rows of perforations 1'. It can be moved in any direction.

That is, each sprocket belt 81, 8r is shown in FIGS. 3 and 4 (belts 81, 8r are partially cut away).
As shown in , the lower dog pulley 101.10r and the small pulley 111.11r diagonally above it are hooked, and the left and right dog pulleys 101. Boo'J 11 it and 11 r are connected to each other by a rotating shaft 13, and furthermore, the drive shaft 12 is connected to the ratchet wheel 1 of the aforementioned transfer drive mechanism a.
When the ratchet wheel 14 rotates, the left and right sprocket belts 8d and 8r rotate simultaneously.

As shown in Fig. 2.4.5, the transfer drive mechanism a has a normal transfer piece 15 on the front side of the ratchet wheel 14.
Further, a reverse feed piece 15' is arranged on the rear side, and both of these feed pieces is and is' are connected to a pair of electromagnets 16 and 1, respectively.
The ratchet wheel 14 is connected to the plungers 17 and 17' of the ratchet wheel 14 by pins 18 and 18', and the forward and reverse directions of the ratchet wheel 14 are determined depending on which of the magnets 16 and 16' is driven.

That is, both feed pieces 15, 15' are always held together by their claws 21.2 due to the springs 19, 19' acting on them individually and the spring 20 stretched between them.
1' is set at the upper limit retracted position where it does not engage the ratchet wheel 14, but the corresponding electromagnet 16
, 16' are repeatedly energized and deenergized by inputting a pulse electric signal, and as the plunger 17 or 17' moves up and down, the guide pieces 22, 16' rotate slightly, respectively.
23, 22', and 23' downwardly by -L to repeatedly engage and disengage with the ratchet wheel 14.

Therefore, depending on which of the pair of electromagnets 16 and 16' is driven, the forward or reverse direction of the ratchet wheel 14 is determined, and depending on whether the card 1 is sent in the forward direction or in the reverse direction (lower side in Figure 2). The direction in which it is sent is determined.

As mentioned above, the card 1 optically scans horizontally and in a straight line, and if there are irregularities on the line to be scanned, the accuracy of reading the information recorded on the card 1 may be affected. In order to prevent this, the left and right sprocket belts 8A and 8r
A card receiving plate 24 is stretched between the left and right belts 8d.

On the left and right sides of 8r, left and right card holding pieces 251 and 25r are provided to lightly press the left and right edges of the card 1, respectively.

That is, as shown in FIG. 3, the upper surface of the card receiving plate 24 is a flat inclined surface that is high on the rear side and low on the front side.
In addition, each card holding piece 251, 25r has a fulcrum on the axis of the drive shaft 12, as shown in the side view of the right side in FIG. It can be rotated, that is, opened and closed, but the spring 26
The card 1 is urged backward, that is, in the closing direction by
'Wosprocket belt 81j, Sr sprocket 8
' and is pressed by the card holding pieces 251, 25r, the card is transferred along the flat inclined upper surface of the card receiving plate 24 while remaining in close contact therewith.

As described above, the portion of the card 1 along the card receiving plate 24 always forms a flat slope over almost the entire length on the left and right sides, and next, the card 1 is scanned horizontally and in a straight line at this fan-like slope portion. A traveling drive mechanism for moving the member will be explained.

Two upper and lower guide rods 27 and 28 are horizontally suspended in parallel to each other on the frame 7, and a scanning member is mounted on these so as to be able to slide left and right.

That is, as shown in FIG. 3, the scanning member has left and right through holes 291 provided in its main body, the running body 29, slidably fitted into the upper guide rod 27, and the running body 29
The bobbin 30 integrally provided on the lower side of the lower guide rod 28
It is fitted in a slidable manner.

A coil 31 is wound around the bobbin 30, and a horizontally long permanent magnet 32 is placed slightly below the lower guide rod 28 in parallel thereto.

The entire length of the upper side of the permanent magnet 32 is, for example, an N pole, and the entire length of the lower side is an S pole.The lower guide rod 28 is made of a magnetic material, and when a current is passed through the coil 31, the current is , the permanent magnet 32 crosses the magnetic field that is constantly created, and the traveling body 2 is moved by the magnetic force acting between them.
9. The scanning member therefore moves automatically to the left or right along the guide rods 27, 28 depending on the direction of the current flowing through the coil 31.

That is, the coil 31 and the permanent magnet 32 are
This constitutes a type of linear morph with 2 as a stator.

At positions corresponding to the left and right ends of the permanent magnet 32, respectively, there are left and right limit switches 33, which act to switch the polarity of the current flowing through the coil 31, as shown in FIG. g, 33r are arranged.

The IJ limit switch 331 on the left side is turned on when the scanning member collides with the left-hand row, and the right-hand limit switch 33r is turned on when the scanning member collides with the right-hand row. The left and right limit switches move left and right between the limit switches 337 and 33r, and these left and right limit switches serve as the left and right stroke ends, and as will be described later, the scanning member is always located at the left stroke end and moves from there to the left stroke end. position, and in conjunction with the reversal of carriage Y, it moves rightward at a considerable speed from its original position to the stroke end on the right side,
As soon as it reaches the right stroke end, it immediately reverses (turns back) and provides continuous feedback to the original position, and the left and right limit switches 331° and 33r are connected to the scanning member. It also functions as a means for detecting whether the stroke is in the original position or in the reversed position (right stroke end).

As shown in FIG. 3, the upper extension part 29' of the scanning member running body 29 extends diagonally upward on the rear side, and then extends diagonally downwardly, and its leading edge is attached to the card receiving plate 24. It faces the inclined surface at a close position, and has a reading element, that is, a light emitting element, at its tip, and a light receiving element that receives reflected light that is reflected from the first surface of the card and converts it into an electrical signal. A so-called photoelectric sensor C consisting of is installed inside.

As the scanning member travels, its photoelectric sensor C optically scans a straight line along the card receiving plate 24 of the card 1. Hereinafter, the photoelectric sensor C will be referred to as a scanning sensor. Make it.

Next, card 1 will be explained with reference to FIG.
On the white surface in between, a knitting pattern recording section 1p, which is a part for recording the knitting pattern, and
The function mark entry field 1f, which is the part for recording function marks, is set to the right side of the organized function information recording part, that is, the function mark entry field 1f, which is the part where function marks are recorded. It is created by displaying the grid division lines (red when red light emitting diodes are used) in advance using an appropriate display method such as printing, and is read by the scanning sensor C on the left side of the knitting pattern entry field 1p. A large number of feed control marks 34, which can control the feed amount of the card 1 by being controlled, are displayed at regular intervals in the direction in which the perforations 1' are arranged, for example, slightly thick black and horizontally long lines. By doing so, you can record it in advance.

The spaces between the entry fields 1p and 1f and between the entry field 1p and the feed control mark 34 are blank.

In the above-mentioned knitting pattern entry field 1p, the vertical lines of the grid division lines that make up the field are the division lines between the knitting gardens, and the horizontal lines are the division lines between the knitting rows, and the bottom side of the field is , the numbers representing the stitches are displayed in the same color as the grid dividing lines.

More specifically, the knitting pattern entry field 1p corresponds to one minimum section, that is, one witness grid or one stitch,
Its horizontal arrangement, or row, corresponds to one knitting needle, and its vertical arrangement, or row, corresponds to a knitting row (wale), and the horizontal arrangement, or row, corresponds to a knitting stage (wale), and each group consists of n stitches of varying width. When knitting so-called unit patterns, the vertical line at the left edge and the vertical line n vertical lines to the right are regarded as boundary lines, and between them a picture (knitting pattern) corresponding to the unit pattern to be knitted is drawn. ) is extracted solidly in black using an appropriate writing instrument such as a pencil, as shown in the figure.

For example, when knitting a unit pattern of 12 stitches in a horizontal row by selecting 12 knitting needles as a unit of one group, the vertical line at the left edge and the 12th day's vertical line This is to extract pictures within the range.

At this time, as long as the outline of the picture is within the above range, the inside of the picture may be filled in solidly without filling in the witness grid one by one.

This is because the reading is performed by sampling each witness grid, and this will be explained in detail later.

Further, in the function mark entry field 1f, the horizontal line is on the same line as the horizontal line of the knitting pattern entry field 1p, the vertical line is parallel to the vertical line of the knitting pattern entry field 1p, and the function mark entry field is The rows (vertical arrangement) of the witness grid in 1f are on the same line as those in the knitting pattern entry field 1p, and have the same number of columns, but the number of rows (horizontal arrangement) is, for example, 36 in the knitting pattern entry field 1p.
However, there are 4.

The function mark entry field 1f is used to mark (for example, fill in black) any witness grid when performing a required function operation.In this example, a total of four witness grid columns (vertical The left column is for programming the forward direction of card 1, and the column to the right is for programming the reverse direction of card 1. The other two columns are for programming necessary function operations other than card feeding, such as thread exchange and starting and ending needle selection operations.

Further, in this example, the feed control marks 34 displayed in advance on the left edge are individually positioned on the extension line of the horizontal center line of each stage of the witness grid in the knitting pattern entry field 1p, and will be described later. Card 1 is automatically advanced to each stage of the witness grid.

Furthermore, in addition to the three types of displays mentioned above, card 1 also has a selection unit number setting field 1s for programming the number of needle selection units in the same color below the knitting pattern entry field 1p. It is displayed in advance.

This setting field 1s displays a required number of independent rectangular witness grids 35 in a row at regular intervals in the horizontal direction, and each of the witness grids has a certain fixed width. They are unique for setting the number of needle selection units, and the number of set units is different from each other, and the number of set units increases in a predetermined base number toward the right, and each witness grid 35 Numbers representing the number of needle selection units are displayed in advance in the same color below.

Regarding this example, the number of witness grids 35 is 6 in total, and the one on the left is the number of needle selection units "6", and the following numbers are 1-12, 18, 24, 30, 36j in hexadecimal. .

Therefore, this needle selection unit number setting field 1s is also scanned by the scanning sensor C of the scanning member, and the needle selection unit is determined depending on which witness grid among the witness grids 35... is to be marked. The number is determined.

For example, when knitting a unit pattern using 12 knitting needles, the witness grid 35 labeled "12" is painted black.

Furthermore, a search mark 36 is preliminarily displayed on the card 1 in order to enable effective reading of only the setting field 1s in the electrical signal processing process after reading by the scanning sensor C as described later.

This mark 36 is composed of, for example, a horizontally long black band with the same vertical width as the vertical width of the witness grid 35 in the setting field 1s, and its position on the card 1 is on the extension line in the direction in which the witness grid 35 is arranged. And it is directly below the feed control mark 34..., but its width is equal to the feed control mark 34...
It is longer on the right side than that of . . . and has a length that includes the width of the blank space between the sending control mark 34 . . . and the knitting pattern entry field 1p.

Then, when the card 1 is loaded onto the left and right sprocket belts 8A and 8r as described above,
When the scanning member is in its original position (left stroke end), a predetermined position within the length range of the feed control mark 34 is read by the scanning sensor C. The card 1 is automatically transferred according to the feed control mark 34, and when the scanning member reaches the reversal position (the right stroke end), the card 1 is transferred to the witness grid at the right end of the function mark entry field 1f. The column is readable, and the range between the two reading positions is read during the movement of the scanning member.

Therefore, before starting the knitting operation, the card 1 scans the needle selection unit number setting field 1s using the scanning sensor C of the scanning member, and then repeats the automatic step-by-step feeding with the knitting operation. Accordingly, the knitting pattern entry field 1p and the function mark entry field 1f are scanned for each stage by the same scanning sensor C, and such scanning is performed by the forward and backward motion steps of the scanning member as described above. However, as will be described later, only the electrical signals associated with the forward (rightward) stroke of the scanning member are effectively extracted from the electrical signals associated with the scanning of both the forward and backward strokes.

By the way, as mentioned above, in the knitting pattern entry column 1p,
The knitting pattern representing the unit pattern to be knitted is drawn solidly, and the scanning sensor C of the scanning member scans it horizontally and linearly for each stage of the witness grid. The electrical signal related to step scanning is the first
As shown in Figure 3 [■] (an example when card 1 is scanned along the P2-P2 line in the same figure), the pattern is The electric signal obtained by scanning does not have a one-to-one correspondence with the knitting needle to be selected, and the electric signal obtained by scanning does not have a one-to-one correspondence with the knitting needle to be selected. The function mark is also read by the scanning sensor C in the same way as the knitting pattern, and becomes an electrical signal in the same electrical system, and the search mark 36, which is displayed in advance, is also read in the same way. These three types of electrical signals are read and converted into electrical signals in the same electrical system, but these three types of electrical signals are separated from each other, and the electrical signals related to reading the knitting pattern are converted into digital electrical signals that correspond one-to-one with the knitting needles. The electrical signals that are converted into signals and related to reading the function marks are separated into each witness grid row (vertical row) in the function mark entry field 1f. The mechanical configuration will be explained with reference to FIGS. 2 and 3.

The frame 7 is located behind the running book 29 of the scanning member.
The horizontally long plate-shaped linear encoder 37 is connected to the guide rod 27.
, 28 and horizontally mounted.

In order to sample only the search mark 36 on the card 1, one linear encoder 37 is installed at a position corresponding to a blank space between the feed control mark 34... and the knitting pattern entry field 1p on the card 1. A search mark sampling slit 383 is provided, and a knitting pattern entry column 1 is provided on the right side of the slit 383 for search mark sampling.
A predetermined number (120 in this example) of knitting pattern sampling slits 38p for sampling the knitting patterns drawn in p are placed from the position corresponding to the left witness grid row in the knitting pattern entry column 1p. They are arranged in a straight line to the right at regular intervals to a predetermined position beyond the right edge of the entry field 1p, and further to the right are a predetermined number of function marks (in this example, four) for sampling the function marks. ) are formed in one-to-one correspondence with each witness grid row in the function mark entry field 1f.

On the other hand, on the rear side of the scanning member 29, there is a photoelectric sensor, ie, a linear encoder 3, for optically reading the three types of slits 38s, 38p, and 38f.
A sampling sensor d consisting of a light emitter that illuminates the front surface of the sensor 7 and a light receiving element that receives the reflected light is attached.

As the scanning member moves, the sampling sensor d moves through the slits 38s, 38p, and so on.

It outputs a pulse corresponding to 38f, that is, a sampling pulse, and the sampling pulse is generated in the reciprocating stroke of the scanning member as described later, as in the case of the electric signal related to the scanning of the scanning sensor C described above. Of these, only those related to the work schedule are retrieved as valid ones as shown in Figure 13, and after that, three types of sampling pulses, that is, those for sampling the search mark 36 are extracted. One sampling pulse, 120 sampling pulses for sampling the knitting pattern, and 4 sampling pulses for sampling the function mark are separated from each other.

By the way, when sampling the knitting pattern, the number of Surin 1-38p was 120 and 120 sampling pulses were obtained because the number of columns (horizontal arrangement) of the witness grid in the knitting pattern entry field 1p was 36
This is to make it possible to apply a card (FIG. 26) with the number of rows of 120J, as will be described later, in addition to the above-mentioned card 1 having the number of rows of 120J.

Therefore, for card 1 whose number of columns is "36",
There are three slits 38p for each witness grid in the knitting pattern entry field 1p, and each witness grid 1 corresponds to three slits 38p.
Three sampling pulses are changed for each scan, but as will be described later, when organizing cards 1 with the number of columns "36", the above three sampling pulses are changed as shown in Fig. 13 (XV). Two of the sampling pulses are removed so that the remaining sampling pulse samples the electrical signal associated with the scanning of one witness grid.

In this way, the electrical signal related to one stage scanning of the knitting pattern entry field 1p is sampled for each witness grid, and
As shown in the figure (XVD), each pit corresponds to each witness grid, and therefore one knitting needle, and is converted into a digital electrical signal that determines whether it is "1" or "O" depending on whether each witness grid is marked or not. The digital electrical signals are sequentially stored in a predetermined memory from left to right, as will be described later.

Then, the stored digital electric signal is transferred to the carriage Y.
The needles are sequentially and repeatedly read in accordance with the running timing of the carriage Y, and are supplied to one of the pair of left and right knitting needle selection mechanisms (this configuration will be explained later) that is to be operated effectively. It is now possible to do so.

The reading device A is mechanically configured as described above.

Next, we will discuss the mechanical configuration of the carriage Y side in Sections 3.8 to 3.8.
This will be explained with reference to FIG.

As mentioned above, the main hand knitting machine automatically starts running the scanning member by reversing the left and right running of the carriage Y.
In order to do this, it is necessary to automatically detect the reversal of the carriage Y in left-right travel, and the effective scanning of the knitting pattern by the scanning sensor C of the scanning member is performed only during the working process, and digital electrical signals related to the scanning are transmitted. While the needles are temporarily stored in the memory sequentially from left to right, the actual needle selection operation is performed by reading out the digital electrical signals stored in the memory. This is done on the reciprocating side of the carriage Y while alternating movements depending on the direction.In order to knit the pattern according to the knitting pattern drawn on card 1, the traveling direction of the carriage Y is detected and the detection signal is used to knit the pattern. The storage of digital electrical signals in the memory and the reading thereof must be controlled.

Therefore, the rear side of the carriage Y is shown in FIG. 8 (the right half of the carriage Y shows the top surface of the plywood with the top cover removed, and the left half shows the back surface) and It is equipped with a carriage reversal switch mechanism E at the center of the edge, and this will be explained first.

A horizontally rectangular body 39 is fixed on the base plate 4 of the carriage Y, and a switch actuator 40 is fitted therein so as to be able to slide back and forth within a predetermined length range from side to side.

The switch actuator 40 is made into a single plate-like unit by sandwiching a connecting piece 41 having a T-shaped cross section and a magnet piece 42, which slide on the upper surface of the essence 39, between two front and rear magnetic plates 431, 432. And those two magnetic plates 431 and 432 are magnetic.
The lower end of the horizontally elongated hole 4' provided in the base plate 4 and the base plate 4
The lower end surface of the magnetic plate 431.43□ is inserted into the needle bed X.
It is designed to be constantly attracted to a carriage guide bar 45 made of a magnetic material and placed horizontally above.

On the other hand, on the rear side of the essence 39, a microswitch e having three switch parts e1 to e5 is fixed inside, and the lever e/ of the switch e is connected to a window provided on the rear wall of the essence 39. The hole 43 of the magnetic plate 432 on the rear side passes through the hole 3γ.
' is involved.

Therefore, the switch actuator 40 is fitted into the essence 39 so as to be able to slide freely within a predetermined range from side to side, and because it is attracted to the carriage guide bar 45, the carriage Y is moved to the left. When the carriage Y is moved to the right, it is slid to the right sliding limit position with respect to the essence 39 and then moved together with it, and when the carriage Y is moved to the right, it is slid to the left sliding limit position in the opposite way to the above. The lever e' of the microswitch e is switched to the left or right by the left/right switching operation of the switch actuator 40, and the switch e is operated to switch to one of the carriage running directions. From the switch part e1 for detection (Fig. 160) or the first
As shown in FIG. 8(n), by reversing the running of the carriage Y, a binary electric signal is reversed from rHJ to rLJ or vice versa.

Next, the left and right knitting needle selection mechanisms FA and Fr, which ultimately select the front and rear needles of the knitting needles N, will be explained with reference to Figs. 3 and 8-10. However, they have essentially the same structure.

The electromagnet 46 is installed on the carriage base plate 4, and
The upper and lower magnetic poles each have a single piece integrally molded with magnetic material.
One ends of the pair of magnetic conductors 147 and 48 are joined from above and below, respectively, so that different magnetic poles are excited in both magnetic conductors 47 and 48.

On the other hand, a bat guide 49 made of a non-magnetic material is fixed to the lower surface of the carriage base plate 4.

This bat guide body 49 has a bat passage 491 long from side to side on its lower surface, and in the bat passage 491,
The loose l-N' of the knitting needles N set at the needle selection receiving position can be received through the side cam 50.

The front and back of this bat passage 49□ are almost the same as those of the bat N', and its upper wall surface is tapered so that the outer half 492 on the outside as seen from the carriage Y descends inward, as shown in FIG. On the surface, the inner half 493 is bat N
The horizontal plane is slightly lower than the steady height of ′.

Therefore, in the process of passing through this bat passage 49□, the rose l-N' is gradually pushed down from the middle of the outer half 49□ against the plate spring 51 (FIG. 3), and in the process of passing through the inner half 493. It comes into pressure contact with the batt passage 491 and passes through it in a snugly fitted state.

In the bat guide 49 having such a structure, the one magnetic conductive body 47 has the outer end of the horizontal portion below the carriage base plate 4 embedded in the thickness of the bat guide 49 from the front side. , a part thereof faces the inner end of the bat passage 49□, and the lower surface of the horizontal part faces the inner end of the bat passage 49□.
The surface is flush with the inner half 493 of the upper wall surface and continues therefrom.

Further, the other magnetic conductor 48 has a notch 481 extending halfway from the upper side in a vertical portion below the carriage base plate 4, and the electromagnet 46 Although the magnetic force acts on the inner vertical portion 483, it hardly acts on the inner vertical portion 483.

The magnetic conductor 48 is arranged so that its outer vertical portion 482 is along the rear wall surface of the bat passage 491.
At the same time, the vertical front surface from the outer vertical part 48□ to the inner vertical part 483 extends inward and rearward from the inner end (bat outlet) of the bat passage 491, as shown in FIG. The surface is inclined.

Further, the horizontal width of the outer vertical portion 482 of the magnetic conductor 48 is a width t that is slightly shorter than the arrangement pitch of the knitting needles N, and the batt N' passing through the batt passage 491 is in the middle of this t mountain, the outer vertical portion 48 □ The rear surface is brought into pressure contact with the vertical front surface of the magnetic conductor 48, and the head end is brought into pressure contact with the horizontal lower surface of the other magnetic conductor 47. A rearwardly inclined gap passage 51 (FIG. 8) is formed between the rear end edge and the batt N'.

Thus, the knitting needles N whose batts N' are fitted into the batt passages 491 are selected in the following manner.

The bat N' that has entered the bat passage 49□ is gradually pushed down with its back and forth movement restrained as the carriage Y travels, and its head end is brought into pressure contact with the horizontal lower surface of one of the magnetic conductors 47, and the bat N' The rear surface is brought into pressure contact with the vertical front surface of the other magnetic conductor 48 while passing through the magnetic conductor 48 .

If the electromagnet 46 is in an excited state while the carriage Y is traveling for one pitch of knitting needles, the magnetic conductor 47
By energizing different magnetic poles in and the outer vertical portion 482 of the magnetic conductor 48, a kind of magnetic path is formed between them via the butt N', and the outer vertical portion 48□ of the magnetic conductor 48 is excited. Because it is tilted backwards, the bat N'
is slightly attracted and biased rearward along its outer vertical portion 482 and deviates from the horizontal lower surface of the magnetic conductor 47 into the gap passage 5.
1, and immediately rises to a normal height on the rear side of the horizontal portion of the magnetic conductor 47.

The butt N' that has entered the gap passage 51 is formed on the carriage base plate 4 by the rising part of the magnetic conductor 47 and the rising part extending from the inner vertical part 483 (portion not subjected to the magnetic action of the electromagnet 46) of the magnetic conductor 48. By disposing a magnet piece 52 between the carriage Y and the carriage Y, the magnet piece 52 is subsequently attracted and biased rearward, and the carriage Y passes through a rearward guide passage formed by a group of cams arranged on the back surface of the carriage Y.

On the other hand, when the electromagnet 46 is in a non-energized state, the bat N' is not attracted to the outer vertical portion 48□ of the magnetic conductor 48, and passes through the bat passage 49□ while being pushed down by the horizontal portion of the magnetic conductor 47. It continues to go straight, and after rising above the inner edge of the horizontal part and rising to a steady height, it passes through a forward guide path that is different from the case of excitation described above.

The left and right knitting needle sorting mechanisms F7 and Fr can be operated effectively by switching the electromagnetic switching switch section e2 in the microswitch e of the carriage reversing switch mechanism E according to the traveling direction of the carriage Y. Only the electromagnet 46 (in this example, the one on the front side in the direction of movement of the carriage Y) is supplied with power for the needle selection operation.

The left and right knitting needle sorting mechanisms Fl and Fr have the above-described configurations, and the knitting needles N with the butt N' fitted into the butt passage 491 are sorted by the sorting mechanism Fl or Fr on the front side in the direction of movement of the carriage Y as described above. Although the needles are subjected to the sorting action one by one, even the inserted knitting needles N are located outside the range of the needle selection range setting switch activation piece 31.3r, which is the left and right point setting means mentioned above. In the case where the electromagnet 46 does not receive any excitation command and remains in a non-excited state, it is not subjected to the above-mentioned sorting action by the electromagnet 46. This will be explained with reference to FIGS. 8 and 9.

The left and right switch activation pieces 31, 3r both have a cam groove 3□ running left and right on their upper surfaces, and a needle groove
A plurality of protrusions 32 that fit into the knitting needles 2 from above are formed protrudingly on the front end of the lower surface, and a plurality of butt engagement grooves 33 that can snugly receive the butts N' of the knitting needles N are formed on the front side. By fitting the protrusion 32 into the rear end of the needle groove x2 and further engaging the butt N' into the butt engagement groove 33, the needle can be placed at any position on the needle bed X without moving left or right. Although they are the same, the shapes of the cam grooves 31 are symmetrical to each other.

That is, in the left switch activation piece 31, the front and rear cam portions 34°3 forming the front and rear side walls of the cam groove 31 are arranged in such a manner that the front side is on the right and the rear side is on the left. The right switch activation piece 3r has the opposite relationship to the above.

On the other hand, on the base plate 4 of the carriage Y, there is a needle selection end detection switch mechanism Gl, which is a pair of left and right point detection means that operate the switch by engaging the switch activation pieces 31J and 3r as the carriage Y runs. It is equipped with Gr.

The left and right switch mechanisms Gll and Gr have substantially the same structure, although the mutual arrangement of component parts is symmetrical.

The crank 53 is connected to the carriage base plate 4 by a pivot 54.
A protrusion 55 is provided on the lower surface of the carriage base plate 4 to project downwardly through the window hole 4'' of the carriage base plate 4. Place the part on the base plate 4
The crank 53 is connected to the lever of the microswitch 56 mounted above, and as the carriage Y travels, the protrusion 55 passes through the cam groove 3□ of the left or right switch activation pieces 31, 3r. It rotates to switch a microswitch 56.

That is, the left and right switch mechanisms Gl and Gr microswitches 56 and 56 have corresponding protrusions 55.
, 55 are both turned on when they are within the distance between the left and right switch activation pieces 3# and 3r, and are turned off when they are outside this distance.

The left and right protrusions 55.55 are the sorting points of the left and right knitting needle sorting mechanisms Fl and Fr, that is, they are located on the rear extension line of the width portion, and the left and right switch mechanisms (J , Gr are switched when the sorting points of the left and right knitting needle sorters 1iFA' and Fr approach the installation positions of the switch actuating pieces 31 and 3r on the needle bed X, respectively, as shown in FIG. 18 (III), ( IV
) As shown in (fHJ), an electrical signal that is inverted to "L" or vice versa is output, and the electrical signals of both switch mechanisms Gl and Gr are connected to the microswitch of the carriage reversal switch mechanism E. Only the part on the side where the effective needle selection operation is performed is taken out by the switch part e3 for indicating the effective needle selection range in e.

Therefore, as shown in FIG. 18(V), the effective needle selection range indicating switch part e3 is turned off after the needle selection end detection switch mechanism 07 or Gr on the side that performs effective needle selection is switched on. In other words, while the needle selection point of the knitting needle selection mechanism Fl or Fr on the front side in the direction of movement of the carriage Y is within the interval between the left and right switch activation pieces 31 and 3r,
It outputs a signal rHJ that indicates the effective needle selection range, and outputs a signal rLJ when it is outside the above interval range, and the above "H"
During output, the above-mentioned memory storing the digital electrical signals related to the knitting pattern is read out, and only during that time the electromagnet 46 on the side that performs the effective needle selection operation is controlled to be energized or de-energized. There is.

In this way, the reading of the memory is performed only within the effective needle selection range determined by the left and right switch activation pieces: l' and 3r, but the reading is performed only when the traveling speed of the carriage Y is not constant and fluctuates greatly. Carriage Y
It must be done in accordance with the running timing of

Therefore, photoelectric sensors Hl and Hr are attached to the carriage Y at the rear end of the base plate 4 at positions corresponding to the left and right knitting needle sorting mechanisms Fl and Fr, respectively. However, slits X3, which are arranged on the rising wall X1 at the rear end of the needle bed X in a one-to-one relationship with the needle grooves X2, are used as a kind of linear encoder to control the movement of the carriage Y. By reading this, the photoelectric sensors Hl and Hr output a pulse, that is, a timing pulse, that matches the traveling timing of the carriage Y, as shown in Figure 18 [■], and this timing pulse causes the aforementioned timing pulse to be output. It controls the reading of the memory, and the following is a photoelectric sensor H1! ,
Hr will be referred to as a timing pulse generator.

Note that, of the pulses from the left and right timing pulse generators HA and Hr, only those corresponding to the knitting needle selection mechanism Fl or Fr on the side that performs the effective needle selection operation are taken out as valid by the carriage reversal switch mechanism E. It has become.

The mechanical configuration of the hand knitting machine is as described above, and next, the electrical and electronic configuration will be explained.

First, the card 1 is scanned and fed,
An outline of the configuration of the input function section that stores the read knitting pattern as a digital electric signal in Memo'JMEM will be explained with reference to FIG.

Of the electric signals related to card scanning by the scanning sensor C, only those related to the rightward stroke of the scanning member from the original position, which is the left stroke end, to the reversed position, which is the right stroke end, are valid by the effective scanning data forming circuit C. Card feeding and scanning instruction circuit C81, needle selection unit number setting circuit NS, and memory control circuit MC.

The signal is input to the function discrimination circuit FS.

The card feeding and scanning instruction circuit C8 includes a left limit switch 33 which is a scanning member original position detection means! ! The electrical signal when the is turned on is input.
The instruction circuit C8 outputs an electrical signal from the effective scanning data forming circuit C to rHl only when the scanning member is in its original position.
or "L", that is, whether the display on the card 1 is a mark or no mark, and supplies an electric signal according to the judgment result to the card feeding and scanning control circuit SC. As a result, the control circuit SC controls the card feed drive circuit CD according to the above mark and no mark, and the electromagnet 1 for card feed.
6 or 16' is driven, whereby the card 1 is automatically transferred by the interval of the search mark 36, feed control mark 34, etc. displayed thereon.

Further, the instruction circuit C8 is configured to receive an electric signal representing the effective needle selection range from the effective needle selection range instruction switch section e3'', and the instruction circuit C8 is configured to input an electric signal indicating the effective needle selection range from the effective needle selection range instruction switch section e3''. When the needle moves from within the effective needle selection range divided by the switch activation pieces 31 and 3r, an instruction signal for starting the scanning member to travel is input to the control circuit SC. The circuit SC is configured to receive an electric signal when the right limit switch 33r, which is the scanning member reversal position detection means, is turned on, and thereby the control circuit SC controls the scanning member drive circuit SD. , thereby also causing the drive circuit SD to supply the coil 31 of the scanning member with sufficient current to enable the scanning member to travel back and forth in one go.

On the other hand, among the sampling pulses related to the linear encoder reading of the sampling sensor d, only those related to right row scanning are taken out as valid ones by the effective sampling pulse forming circuit and inputted to the pulse separation circuit PS. The pulse for sampling the search mark 36 above, the pulse for sampling the knitting pattern, and the pulse for sampling the function mark are separated from each other, and
Here, the pulses (120 pulses in total) for sampling the above-mentioned knitting pattern are for each witness grid when using card 1 in which the number of rows of the witness grid in the knitting pattern entry field 1p is "36" as described above. Two pulses are thinned out and the remaining pulses are sent to the write address designation circuit WA and the memory control circuit MC, and one pulse for sampling the search mark 36 is sent to the needle selection unit number setting circuit. NS, and four pulses for sampling the function mark are respectively input to the function discrimination circuit FS.

The number of needle selection units setting circuit NS samples the electric signal related to the reading of the search mark 36 from the effective scanning data forming circuit C according to the one input pulse, and thereby sets the number of needle selection units. This is an instruction to electrically preset the sampling mode of the mark in column 1s, that is, the number of needle selection units, and the setting circuit N.
S is inputted with the pulse before thinning for sampling the knitting pattern from the pulse separation circuit PS, and at which pulse, the effective scanning data forming circuit C inputs the number of needle selection units setting column 1s. Depending on whether the electrical signal related to mark reading is input, the number of needle selection units will be electrically preset by the digital electrical signal of the number of needle selection units programmed in the needle selection unit number setting column 1s. ing.

Then, the needle selection unit number setting circuit NS determines whether or not to thin out the pulses for sampling the knitting pattern and how many pulses to thin out in accordance with the stored number of needle selection units. For example, when the number of needle selection units is between "6" and "36", the pulse separation circuit PS is controlled to thin out two needles at a time as described above. The setting circuit NS receives an instruction to electrically preset the number of needle selection units as described above, and controls the card feeding and scanning instruction circuit C8 and the card feeding and scanning control circuit SC,
After the scanning member scans the needle selection unit number setting field 1s once and returns to its original position, the card 1 is read from the bottom mark among the scanning member feed control marks 34... It is designed to automatically transport up to

, the write address designation circuit WA includes a binary counter that counts the pulses input from the pulse separation circuit PS as described above, and writes a parallel binary electrical signal in accordance with the counting result to the memory control circuit MC to designate an address. It is designed to be input as a signal.

The memory control circuit MC samples the electrical signal related to the scanning of the knitting pattern from the effective scanning data forming circuit C using the pulses from the pulse separation circuit PS as described above, and samples the electrical signal related to the scanning of the knitting pattern from the effective scanning data forming circuit C, and assigns the electrical signal to each knitting needle and each bit corresponding to each other. After converting the digital electrical signal into a digital electrical signal (see FIG. 13 (XVI)), the digital electrical signal is sequentially transferred to a certain fixed address in the memory MEM under the addressing control of the write address designating circuit WA, and also when the carriage is traveling. An electric signal corresponding to the carriage running direction from the direction detection switch e1 is used to store the left-hand scanning of the carriage Y and the right-hand scanning in separate storage sections, that is, two storage sections. This will be explained in detail later with reference to FIG. 21.

The function discrimination circuit FS uses the four pulses inputted from the pulse separation circuit PS as described above to
The electric signal related to function mark scanning from the effective scanning data forming circuit C is entered in the function mark entry field 1f.
Samples are taken for each entered grid row, and the sampling of the two columns on the left side of the entered grid row is inputted to the card feeding and scanning control circuit SC, to which the card 1 is sent either in the forward direction or in the reverse direction. In addition, the sampling related to the two columns on the right side is inputted to the function drive circuit FD, which controls necessary function operations such as thread exchange operation.

Further, the card feeding and scanning instruction circuit C8, the control circuit SC, and the memory control circuit MC operate a manual operation means, that is, a clear button CB provided on the operation panel 2 (FIG. 1) of the control box B. This enables manual control, and by operating the button, the card 1 can be transferred by one step in the direction opposite to the transfer direction before the button operation, and the data currently stored in the memory MEM can be cleared. This is to facilitate re-knitting in case of incorrect knitting.

Further, the card feeding and scanning control circuit SC is controlled by operating another manual operation means, that is, a stop button SB, which is also provided on the operation panel 2, and the transfer of the card 1 can be stopped by operating the button. It is possible to do so.

Furthermore, when performing a special organization, by operating the special function button W, which is also provided on the operation panel 2, the card feeding and scanning instruction circuit C8 is controlled, and the card feeding and scanning perform special operations. It is now possible to do so.

Next, the detailed configuration of the effective scanning data forming circuit C1 effective sampling pulse forming circuit D1 pulse separating circuit PS1 needle selection unit number setting circuit NS and function discrimination circuit FS will be explained with reference to FIGS.

The R-S flip-flop 60 is set by the limit switch 331 on the left side, which is a scanning member original position detection means, and reset by the right limit switch 33r, which is a scanning member reversal position detection means, so that the scanning member is in its original position. AND gate 61c only during the working process of traveling from to the reverse position.

61d is opened, and only during this time the output signal of the scanning sensor C and the sampling sensor d are
and the output signals of the effective scanning data forming circuit C1, respectively.
The output signal of the effective sampling pulse forming circuit is Antogedro 1c.

61d (Fig. 13 (V
), (see [I]).

As shown in FIG. 13 [■], the output of the limit switch 331 becomes IH, J when the scanning member moves away from the original position at rLJ, and this output causes the search mark to be An R-S flip-flop 62 for separating 36 sampling pulses is set when the scanning member leaves the original position, and the first pulse from the effective sampling pulse forming circuit (the above search mark) is set when the scanning member leaves the original position. 36 sampling pulses)
It is reset by the falling edge of .

The Q output of this flip-flop 62 opens the AND gate 63 which receives the pulse from the effective sampling pulse forming circuit. Pulses other than the pulses for sampling the search marks 36, that is, the pulses for sampling the knitting pattern and the pulses for sampling the function marks, are output.

On the other hand, the Q output of the flip-flop 62 is added to the AND 64, which is the Q output of the flip-flop 62.
When the output, the output of the effective scanning data forming circuit C, and the output of the effective sampling pulse forming circuit are both rHJ, that is, the scanning sensor C detects the search mark 36 on the card 1 and the selection unit number setting field 1S. When performing cross-scanning (scanning along the P1-P1 line in FIG. 13, (■ in the same figure is the output waveform of the effective scanning data forming circuit C at that time), the sampling sensor d is connected to the search mark sampling slit of the linear encoder 37. When 38 seconds is detected, one pulse is output as shown in [■].

Therefore, this pulse output from AND64 is
This indicates that the search mark 36 has been detected.

The R-S flip-flop 65 stores the fact that the search mark 36 has been detected by the output of the AND 64 (actually, the output is inverted by the knot 64').
is now set.

This flip-flop 65 is reset by the output of AND66.

The AND 66 is inputted with the Q output of the flip-flop 65, the Q output of the flip-flop 62, the output of the effective scanning data forming circuit C, and the output of the effective sampling pulse forming circuit. In Fig. 13, the output is (III), [:IV),
(V), as is clear from the comparison of C.
When HJ is reached, that is, after the search mark 36 is detected as described above, when the mark made in the needle selection unit number setting field 1S is detected, one pulse is emitted as shown in the figure. The flip-flop 65 is reset by this pulse.

Therefore, the flip-flop 65 stores the fact that the search mark 36 has been detected as shown in [period] only until the mark in the needle selection unit number setting column 1s is detected.

In addition, the above-mentioned one pulse also controls the above-mentioned card feeding and scanning instruction circuit C81 and the same control circuit SC as will be described later.

On the other hand, the pulse (IV) from the AND gate 63 from which the pulse for sampling the search mark 36 has been removed as described above is sent to the hexadecimal-binary counter 67, specifically, the pulse (IV) directly counted by the hexadecimal-binary counter 67. The pulse CIVI is counted by a counter consisting of a hexadecimal counter and a binary counter that converts the count value of the hexadecimal counter into a binary number.
) is counted, the count value of the counter 67 increments by one.

The count value of this counter 67 is the output of the ant 66 [
■] When the mark in the needle selection unit number setting field 1S is detected by the gate network 68 which uses the gate operation signal as the gate operation signal, the memory 6
9, and then subsequently stored in memory 69.

This memory 69 stores the output (2) of the flip-flop 65.
), that is, when the search mark 36 is sampled.

Further, the count output of the counter 67 is
The signal is input to a gate network 70 that discriminates whether the number of pulses X from 3 is within 120 or 121 or more.

This gate network 70 performs the above discrimination on the parallel output from the counter 67 using a logic circuit formed by a combination of gates, and if it is within the above 120, the parallel output from the rlJ output terminal as shown in And gate 71 produces an output
1 is opened, and if it is 121 J or more, an output is generated from the output terminal of "2" and the AND gate 711 is opened.

Therefore, the AND gate 111 outputs 120 pulses for sampling the knitting pattern, as shown in Figure 1, and the AND gate 111 outputs 120 pulses for sampling the knitting pattern, and the AND gate 111 outputs 120 pulses for sampling the knitting pattern, as shown in Figure 1. Four pulses will be output.

The 120 pulses from the AND gate 71□ are input to a pulse selection circuit 72, where they are divided into three types of pulses.

That is, the pulse selection circuit 72 has its "1" output system passing through the 120 pulses as is, as shown in FIG.
It includes a type flip-flop and an AND gate connected to this output side, and as shown in [■], it thins out even-numbered pulses out of 120 pulses and outputs the rest. The output system of "3" includes a ternary counter and an AND gate connected to this output side, and as shown in ○■], 3n- out of 120 pulses
The 1st (where n is an integer) pulse is left and the others are thinned out.

On the other hand, as mentioned above, the output of the memory 69, which indicates the number of needle selection units programmed in the needle selection unit number setting field 1s in the card 1, is the above-mentioned three types output from the pulse selection circuit 72. A gate network 73 for selecting which of the pulses is actually used as a sampling pulse.
If the number of needle selection units is between 6 and 36, an output is generated from the output system "3" of the gate network 73, the AND gate 743 is opened, and one of the three types of pulses (KV )
The pulse of 0 passes through the OR 75, and if it is between 42 and 60, an output is generated from the output system of "2", opening the anti-gate door 4□, and the pulse of 0 passes through the OR 75.
If it is between 66 and 120, an output will be generated from the "1" output system and the ant game will pass through.
) 74 are opened so that the pulse of I■] passes through the OR 75.

In this way, the sampling pulses for sampling the knitting pattern are divided into three types, and the pulses are selectively extracted depending on the number of needle selection units. The number of witness grid rows in the knitting pattern entry field 1p is 36, and the number of needle selection units is 6, 12, 18, 24, 3.
In addition to cards that can be selected as 0 and 36, as shown in Figure 24, the number of witness grid rows is 60 and the number of needle selection units is 4.2.
゜48. Cards that can be selected as 54 or 60, and as shown in Figure 25, the number of witness grid rows is 120 and the number of needle selection units is 6.
6.72,78,84,90,96゜102.108,
This is because a total of three cards, which can be selected as 114 and 120, are used depending on the number of needle selection units.

Incidentally, when the card 1 shown in FIG. 2 is used, the pulses output from the OR 75 are a total of 40 pulses as shown in FIG. The output of the effective scanning data forming circuit C (when the scanning sensor C scans the card 1 along the P2-P2 edge in FIG. In addition, the output related to the scanning of the knitting pattern entry field 1p is converted into a digital electrical signal corresponding to the knitting needle in a one-to-one relationship as shown in [■]. Thereafter, the data is sequentially stored at a certain fixed address in the memory IJMEM by the address designation operation of the write address designation circuit WA shown in [Kariji].

The digital electrical signals are stored in the memo IJMEM for all of the input grids in the first row of the knitting pattern entry field 1p from the left edge to the right edge as described above, but their readout is performed only when the selection is made. This is repeated only for the number of needle selection units set in the needle unit number setting field 1S. The output is converted into a binary number by a code converter 76 and input to a read address designation circuit RA, which will be described later.

On the other hand, four pulses [■] for function mark sampling are output from the AND gate 71□.
are separated from each other by a pulse discrimination circuit 77 composed of a gate group.

That is, the four pulses are counted by the counter 78, and the decoder 79 outputs signals from the output systems "1" to "4" as shown in (XV[) and (XI)0, respectively, according to the number of pulses. generates an output and opens the gates in the pulse discrimination circuit 77, thereby causing the output systems "1" to "4" of the pulse discrimination circuit 77 to
X), C■], the outputs are sequentially generated in accordance with the order of the pulses.

The four pulses separated by the pulse discrimination circuit 77 are input to a function memory circuit 80 composed of a D-type flip-flop, etc., and the output [■] from the effective scanning data forming circuit C is sampled here. is performed for each grid column in the function mark entry field 1f, and the sampled data is stored separately for each grid column as shown in [*old].

Then, rlJ to r of this function storage circuit 80
r I J of the four output systems of 4J.

The output of "2" is input to the aforementioned card feeding and scanning control path SC, which will be explained in detail later, and the output of "1" controls the forward feeding of card 1, and the output of "2" The output of ``3'' is designed to control reverse direction feed.
"," and "4" are input to the aforementioned function drive circuit FD to respectively control required function operations other than card feeding.

Next, the card feeding and scanning instruction circuit C8 and the same control circuit S
The specific configuration of C will be explained with reference to FIGS. 14 to 18.

The above-mentioned clear button CB is used not only in case of incorrect organization as mentioned above, but also as a kind of start button to start the organization when starting the organization using card 1. Before explaining the operations caused by this, an outline of how to use the hand knitting machine will be explained.

First, point setting means 100 (first
4) manually (for example, set to 1), operate the carriage in the usual way to perform the required knitting such as waste knitting, and when you have knitted to the point where you want to add a pattern, set the carriage Y to The knitting needles set at the needle selection receiving position on the floor X are stopped outside either the left or right end.

In this state, the card 1 is fed manually, that is, by turning the ratchet wheel 14 by hand, and set so that the upper and lower intermediate portions of the search mark 36 face the scanning sensor C of the scanning member in its original position. I'll keep it.

Afterwards, press the clear button CB above to clear card 1.
is transferred by one pitch in the forward or reverse direction (the direction at this time is not determined as will be explained later), and then the scanning member is moved along the line Pl-P shown in FIG. 13, for example. During the working process, after the number of needle selection units is set as described above, forward transport of the card 1 is restarted upon completion of the backward movement.

This transfer continues intermittently until the lowermost feed control mark 34 is detected by the scanning sensor C. Upon this detection, the scanning member immediately moves to line P2-P2 in FIG. Travel back and forth along the
Upon returning to the original position, the series of operations by operating the clear button CB ends.

After this, perform the work necessary for pattern knitting, such as inserting the desired colored thread into the thread opening of the carriage Y, and then move the carriage Y to the left and right switch activation pieces 3A and 3r installed on the needle bed X. If the card 1 is repeatedly run back and forth until it exceeds the limit, the card 1 will be fed one step at a time, and the knitting pattern drawn on it will be knitted.

Now, when the clear button CB is operated, the accompanying signal (Fig. 15 [I]) is inverted at knot 81, passes through or 82, and then inverted again at knot 82'.
The card feed and scan instruction signal is output from the card feed and scan instruction circuit C8, and passes through the AND gate 93 in the control circuit SC to the R-S flip-flop 83 for card feed instruction and the R-S for scanning member forward movement instruction. A flip-flop 84 is set.

By setting the flip-flop 83, its Q output (II
I) is applied to a card feed drive control circuit 86 consisting of a gate network through AND85' and AND85,
One pulse shown by the leap line is generated from either the output terminal "1" on the forward direction feed side or the "2" output terminal on the reverse direction feed side of this control circuit 86, for example, the output terminal "2". The aforementioned card feeding drive circuit CD is driven, and either one of the pair of card feeding electromagnets 16, 16' is operated, and the card 1 is transferred in either the forward direction or the reverse direction. It is now possible to do so.

This transfer is performed by the search mark 3 on card 1 as described above.
When the upper and lower intermediate portions of the scanning member 6 are opposed to the scanning sensor C of the scanning member, scanning is performed by a predetermined one pitch.

That is, the card feed drive control circuit 86 drives the card feed drive circuit CD using an output pulse from a timer 87 that determines the feed amount for one pitch of the card 1, and the output pulse is applied to a D-type flip-flop. The flip-flop 83 is reset by the rise of the Q output (IV) of the flip-flop 88.

Further, the output of the effective scanning data forming circuit C is input to the D terminal of the above-mentioned flip-flop 88, and the flip-flop is connected to the right limit switch which is the scanning member reversal position detecting means. 33r
Further, the timer 87 includes an oscillator such as an unstable multi-by-break and a binary counter that counts the oscillation signal, and the output of the counter is counted for a predetermined period of time. The counter is designed to be finally output as a pulse with a width of 100 mm, and the counter is operated only during rHJ output of the AND85'.

The D-type flip-flop 88 is designed to sample and output the input from the D terminal using the rising edge of the input pulse from the T terminal, and the timer 87 is activated by operating the clear button CB as described above. When one pulse is output and card 1 is sent one pitch, the search mark 36 has not yet crossed the scanning line of scanning sensor C either above or below, so a valid signal is sent to the D terminal of flip-flop 88. An rHJ output indicating that a mark has been detected is inputted from the scanning data forming circuit C, and the flip-flop 83 is reset by the output of the flip-flop 88.

Therefore, the timer 87 stops operating after outputting only one pulse, and the card 1 is only sent one pitch.

By the way, when the clear button CB is operated, the RS flip-flop 89 is set, and the feed direction is reversed by its output during the setting time, that is, until it is reset by the fall of the Q output [■] of the above-mentioned flip-flop 88. The circuit 90 is controlled to switch the output operation of the card feed drive control circuit 86, and the card 1
If the clear button CB is operated in the above-mentioned state, the R- button that indicates the direction in which the card 1 is to be transported is
Since it is not determined whether the S flip-flop 91 is in the set state or not, it has not been determined in which direction the one-pitch transfer will be performed.

When this one-pitch transfer is completed, the scanning member moves forward.

That is, when the clear button CB is operated, the scanning member forward movement instruction flip-flop 84 is set as described above, and its Q output is input to the AND 92; Since the signal obtained by inverting the Q output of the flip-flop 89 with the knot 89' is input, the output of the AND92 is input when the flip-flop 89' is being set, that is, when card 1 is being transferred based on the operation of the clear button CB. In this case, the scanning member drive circuit SD described above is not driven once to move the scanning member forward, and the card 1 starts moving forward after it has stopped.

This forward movement ends when the flip-flop 84 is reset by the right limit switch 33r as shown in FIG. 15 [■], and at the same time, the R-S flip-flop 94 for instructing the scanning member to move backward is set As a result, the scanning member immediately begins to move back.

This backward movement is caused by the limit switch 33 on the left side of the scanning member.
However, since the scanning member collides with the limit switch 331 at a considerable speed, the reaction causes the limit switch 331 to be turned on.
31 may chattering as shown in FIG.
The home position return signal from 31 is delayed as will be described later to reset the flip-flop 94, so that the scanning member continues to move to the left even after reaching the left stroke end. This is to prevent the above-mentioned fear from occurring.

As described above, when the scanning member moves back and forth by operating the rear button CB, the needle selection unit number setting field 1s is activated by the needle selection unit number setting circuit NS during the working process.
The number of needle selection units programmed in the unit is electrically set, and when the setting is done, one pulse ( The R-S flip-flop 96 in the card feeding and scanning instruction circuit C8 is set by (4) in FIG.
Flip-flop 8 for card feeding via knot 82'
Set 3 again (1).

However, the card feed drive control circuit 86 is configured such that the signal from the left limit switch 331 can be inputted through the knot 97, and the card feed drive control circuit CD is activated only when the scanning member is in the original position. Therefore, the card 1 is not transferred while the scanning member is running after the number of needle selection units is set.

When the scanning member returns to its original position, the flip-flop 8
3 has already been set as described above, the pulse of the timer 87 is input to the card feed drive control circuit 86, and the card 1 is transferred.

At this time, the transfer direction is set by the one pulse from the needle selection unit number setting circuit NS which sets the flip-flop 91 which instructs the card feed direction via the OR 98, and by the operation of the clear button CB. Since the flip-flop 89, which had been in the 1
'' pulses are output from the output terminal as shown in [■], so it is in the forward direction.

The feed direction reversing circuit 90 is composed of two exclusive OR circuits, and when the output of the flip-flop 89 is rLJ, the input from the flip-flop 91 is directly input to the control circuit 86, and conversely, the output is When rHJ, the above input is inverted, and when set, the flip-flop 91 has a Q output of rHJ.
This instructs to forward the card 1, and when the Q output becomes "H" at the time of reset, it instructs to forward the card 1 in the reverse direction.

The card 1 is first transferred one pitch, but at that time the scanning sensor C is still detecting the search mark 36, so the card is transferred by the output (IV) of the D-type flip-flop 88. The flip-flop 83 is about to be reset.

However, since this flip-flop 83 has priority over the set signal, and the flip-flop 96 supplying the set signal receives the output [X] of the AND 99 due to the subsequent detection of the search mark 36. Since it is not reset (reset by a falling edge) by the output of the valid scanning data forming circuit C which has passed, the set state is still maintained, so that the card 1 continues to be repeatedly and intermittently transferred in the forward direction.

When the search mark 36 is moved away from the position facing the scanning sensor C due to such forward movement, the flip-flop 96 is reset at that moment, and the set signal to the flip-flop 83 for sending the card disappears, but the flip-flop 83 is reset. The input to the D terminal of the D-type flip-flop 88 (output of the effective scanning data forming circuit C) also corresponds to the no mark, so [■]
As shown in FIG. 3, the output of the D-type flip-flop 88 does not reset the flip-flop 83, and the flip-flop 83 still maintains the set state. Therefore, the card 1 continues to be in order even in the no-mark section where the search mark 36 is removed. It will be transported in the direction.

When the lowermost one of the feed control marks 34 is detected by the scanning sensor C due to the continuous forward movement, the D-type flip-flop 88 is detected.
resets the flip-flop 83, thereby stopping the transfer of the card 1.

At the same time, as described above, by operating the clear button CB, the Q output of the scanning member forward movement flip-flop 84, which is in the set state, is reset. By inputting to the circuit SD, the scanning member S reciprocates, the scanning sensor C scans the card 1 along the line P2-P2 in FIG. 13, and when it returns to its original position, the scanning member S stops, This also ends the series of operations described above that were performed by operating the clear button CB.

The digital electrical signal (Fig. 13 [Drama]) representing the knitting pattern obtained by the first one-stage scanning is as follows.
As long as this is the case, the memo IJMEM is written to both of its two memory sections at the same time.
Its configuration will be explained in detail later.

The first scanning of the knitting pattern entry field 1p and function mark entry field 1f of card 1 is automatically performed by operating the clear button CB as described above, but subsequent scanning is performed automatically by operating the clear button CB. This is automatically performed for each stage by reciprocating the carriage Y, which will be explained next.

When the carriage Y moves out of the effective needle selection range defined by the left and right switch activation pieces 3A and 3r (more specifically, the needle selection end detection switch mechanism Gl or G on the front side in the direction of movement
r is turned on), at that moment the comparator circuit 101 in the card feeding and scanning instruction circuit C8 outputs a pulse as shown in FIG. Through ora 82, knot 82'
After being reversed as shown in (II), the card feeding and scanning instruction circuit C8 is used as a card feeding and scanning instruction signal.
The flip-flops 83 and 84 in the control circuit SC are set as shown in QV) and (V), respectively.

By setting the flip-flop 84, its Q output (V
), since the flip-flop 89 is in the reset state as shown in (VI), it passes through the AND gate 92 as shown in □ to drive the scanning member drive circuit SD, thereby causing the scanning member to move forward. let

When the scanning member reaches the reversal position j, which is the stroke end on the right side, the flip-flop 84 is reset by the output □ of the right switch 33r, and instead, the flip-flop 94 for instructing the scanning member to move back is set, and the scanning member moves backwards, and when the left limit switch 337 is turned on, its output (9) falls, causing the delay circuit 95 to operate as shown in (X), and its output resets the flip-flop 94. As a result, even after the scanning member reaches the original position (left stroke end), a force is applied to move the scanning member slightly further to the left.

On the other hand, the flip-flop 83 for instructing card feeding is set at the same time as the flip-flop 84 for instructing the forward movement of the scanning member, as described above, but during the reciprocating movement of the scanning member as described above, the above-mentioned delay occurs. Since the signal obtained by inverting the output of circuit 95 at knot 95' is "L",
The output [■] of the AND 85' is "L", and the card feed drive control circuit 86 is not driven.

When the backward motion of the scanning member is completely completed, the output [■] of AND85' becomes "H", and the timer 87 operates and first outputs one pulse, which causes the card feed drive control circuit CD to start. The operation is as shown in [Drama], and card 1 is first transferred by one pitch.

This one-pitch movement causes the scanning sensor C to miss the feed control mark 34 on the card 1, so the output (XI) of the effective scanning data forming circuit C becomes "L", and the Q output [W] ( Since the output from the delay circuit 95 that passes through the AND 93 continues to be "H" and the flip-flop 83 is not reset, the timer 87 outputs a pulse and the card 1 is further transferred.

When the card 1 is transferred in this way and the scanning sensor C detects the next feed control mark 34, the Q output (XV) of the D-type flip-flop 88 changes to rLJ.
As a result, the card feeding instruction flip-flop 83 is reset, the timer 87 stops operating, and the feeding of the card 1 is stopped.

In this way, when scanning the knitting pattern entry field 1p on the card 1, the one that operates effectively among the left and right knitting needle selection mechanisms Fl and Fr of the carriage Y is created by the left and right switch activation pieces 31 and 3r. When the needle is extracted from within the effective needle selection range to outside the range, the scanning member first moves back and forth, and when the scanning member returns to its original position, the card 1 is immediately transferred one stage. Become.

Therefore, even if it takes a short time for the carriage Y to travel and reverse after the above-mentioned extraction is performed and to enter the effective needle selection range again, scanning is performed accurately within that short time, so the knitting after such travel reversal is possible. is performed correctly even if the carriage Y is moved quickly.

Note that the output of "1" from the function storage circuit 80 in the function discrimination circuit FS (when a mark has been applied to the leftmost entry grid row among the four entry grid rows in the function mark entry field 1f) The output of "2" (output of "2") sets the flip-flop 91 for instructing the feed direction via the OR 98, and the output of "2" (a mark is placed in the second entry grid column from the left edge). The output when the card was applied) is reset, and card 1 can be sent forward or backward by marking any witness grid in the above two input grid rows. can be controlled arbitrarily.

Further, when the above-mentioned stop button SB is operated, the card feed drive control circuit 86 is reset.
Even when the carriage Y is moved back and forth as described above, the card 1 is not transferred and only the scanning member is moved.

Therefore, when the stop button SB is operated,
The card 1 is repeatedly scanned in the same row, and one aspect of the knitting pattern in that row can repeatedly knit a continuous pattern.

Furthermore, the clear button CB functions as a kind of start button when starting the scanning of card 1 as described above, but when it is operated at the stage of scanning the knitting pattern, as shown in FIG. It is clear from the above that the card 1 is transferred one step in the reverse direction, then the scanning member moves back and forth, and then the card 1 is transferred one step again in the original transfer direction. It is.

The input function part described above transfers and scans the card 1, and the knitting pattern drawn in the knitting pattern entry field 1p is read one by one row by row and one-on-one with the knitting needles N.
Memo 1. as a corresponding digital electrical signal in relation to. IM
It is designed to be stored in the EM.Next, the stored digital electrical signal is transferred to the memory MEM by the carriage Y.
The left and right knitting needle selection mechanisms F7. The output function portion that causes the Fr to select the knitting needles N will be explained with reference to FIGS. 19 and 20.

When the carriage Y enters the effective needle selection range, the effective needle selection range indicating switch section e3 of the carriage reversal switch mechanism E outputs the signal "" as shown in FIG.
When "H" is output, the read address designating circuit RA is in the set state only during the output.

This read addressing circuit RA includes an up/down counter as will be explained in detail later with reference to FIG. 22, and the timing pulse generator H! ! , Hr, the timing pulse (1) inputted every time the carriage Y travels by one pitch of knitting needles is counted, and the counted value is determined by the selection from the needle selection unit number setting circuit NS. Parallel binary signal that indicates the number of stitch units (for details, refer to the 12th
By inputting the output of the code converter 76 shown in the figure, the number of needle selection units (in this example, 12) is preset to the same number as programmed in the needle selection unit number setting field 1s of the card 1. At the same time, the switching of addition and subtraction is performed by a signal (n) representing the carriage running direction from the carriage running direction detection switch section e1, and the timing pulse is added according to the carriage running direction. Or it is supposed to be subtracted.

Thus, the read addressing circuit RA
Each time the preset number of timing pulses is counted while the vehicle is running within the effective needle selection range, the same value (parallel binary electric signal) is repeatedly taken as shown in (2).

In other words, it can be said that this circuit RA encodes the knitting needles N between the left and right switch activation pieces 31 and 3r, and assigns repeat numbers to them in a certain direction.

The output of this circuit RA is supplied to the memory control circuit MC as a read address designation signal for the memory MEM, and the signal 1 representing the carriage running direction is supplied to the memory control circuit MC as a read address designation signal for the memory MEM. The digital electrical signal stored in the memo IJMEM is input to the circuit MC as a signal to determine which of the two recording sections of the memo IJMEM is to be read out. In this example, the range is from O to 11 depending on the direction of travel.
The 12 pits are repeatedly read out, and as shown in (2), they are output as binary electrical signals from the memory control circuit MC and input to the waveform processing circuit WP.

The waveform processing circuit WP receives the signals from the effective needle selection range indicating switch e3, and only during the "H" state, the signal from the memory control circuit MC is treated as valid and sent to the electromagnet drive circuit MD. The output of this drive circuit MD is controlled by the electromagnet changeover switch e2 to the electromagnet 46 of the knitting needle sorting mechanism Fd or Fr, which is the one that performs the effective sorting operation.
It is now entered into

Thus, the left and right switch activation pieces 31! , 3r, the knitting needles N are drawn in groups of 12 as shown in [■] between the witness grid at the left end of the knitting pattern entry field 1p and the witness grid 12 to the right of it. Sorting according to the aspect of the knitting pattern (for example, in Fig. 18, the oval indicated by a solid line indicates a forward bias, the filled-in oval indicates a backward bias, and the oval indicated by a broken line is at a rest position where it is not subjected to the needle selection action. ) will be done.

By the way, as mentioned above, the knitting pattern entry column 1p is scanned over the entire length of its left and right ends, and all the hits of the digital electric signal obtained by the one-stage scanning are stored in the memory MEM.
The number of bits that can be read from this is determined by the number of needle selection units programmed by marking the number of needle selection units setting field 1s.For example, if you set it to "12". In this case, even if the knitting pattern is recorded further to the right of the 12th witness grid from the left edge on the knitting pattern entry field 1p, the recorded part on the right side will be scanned and temporarily stored in the memo IJMEM. Although it is stored, it is not read out as a signal for needle selection.

With the above configuration, it is possible to knit a unit pattern according to the knitting pattern on the card 1, but the main hand knitting machine can also knit the pattern actually knitted without changing the knitting pattern. can be changed by manual operation of the manual operation member on the operation panel 2, which will be explained next.

The pattern left/right selection means RL changes the output electric signal to r as shown in FIG.
The signal is inverted from HJ to rLJ or vice versa as shown in [XI:], and the signal is compared with the signal representing the carriage running direction [old] in the comparator circuit CO (exclusive OR). The direction of addition and subtraction of the up/down counter of the read address designation circuit RA is designated by the comparison signal.

Therefore, the count value of the read addressing circuit RA is
It is determined based on the operation of the pattern left/right selection means RL whether the carriage Y takes the above-mentioned relationship [■] or (XV) when traveling in a certain direction.
Even if the knitting patterns on card 1 are the same, the knitted patterns in cases [■] and (XV) have a relationship as if the left and right sides were reversed.

Next, the pattern mode selection means MS outputs an electric signal inverted from rLJ to rHJ or vice versa as shown in the figure by switching the manual operation section, and supplies it to the waveform processing circuit WP. By operating this means MS, the waveform processing circuit WP determines whether to pass the input (X) from the memory control circuit MC as it is without inverting it, or to invert it as shown in the diagram. be.

Therefore, by operating this means MS, the front and rear sorting mode of the knitting needles N can be reversed, and thereby the card 1
This allows the ground pattern of the knitted pattern to be reversed without changing the knitting pattern above.

The outline of the output function part has been described above, and next, the specific structure of the memory control circuit MC is shown in FIG. 21, and the specific structure of the read address designation circuit RA is shown in FIG. This will be explained with reference to FIG.

First, the memory control circuit MC includes a data selector 104 made up of two gate groups 1041 and 104r.

The data selector 104 has one gate group 104r.
is a signal representing the carriage running direction from the carriage running direction detection switch part e1, and is a signal representing the carriage running direction, and
05, and the other gate group 1041 is controlled by a signal that is an inversion of the signal representing the carriage running direction at a knot 106, and which passes through an AND gate 107. This also causes the memory MEM to
Writing and reading of the two storage units MBMI2 are controlled.

That is, when the carriage Y is in the right row, the signal from the AND gate 105 for one gate group 104r becomes "H", and the read address designation signal from the read address designation circuit RA is transmitted to the gate group 104r. When the AND gate 108 is opened, the digital electric signal stored in the memory unit Mr is read out and applied to one of the storage units Mr through the AND gate 10.
8. The signal is applied to the waveform processing circuit WP via the OR 109, and needle selection is performed according to the content, while the signal from the AND gate 107 to the other gate group 1041 becomes rLJ, and the signal is applied to the write address. Designated circuit W
By applying the write address designation signal from A to the other memory section M1 through the gate group 1041, data from the effective scanning data forming circuit C is written to the memory section M1.

This written data is stored in the storage unit M at the same time as writing.
However, since the AND gate 110 is closed, the signal is not input to the waveform processing circuit Wp.

On the other hand, when the carriage Y is in the left row, contrary to the above, writing is performed on the storage section Mr, and reading is performed on the storage section M7.

In addition, when the clear button CB is operated, the signal indicating the carriage running direction (H or L) is displayed.
Regardless of both memory units Ml.

This is so that both Mrs are in the write state.

That is, when the clear button CB is operated, the flip-flop 111 is set, and the AND gates 105,1
07 both output "L", and the write address designation signal is sent to both gate groups 104A of the data selector 104? ,
The data is applied to both storage sections MA and Mr of the memory MEM through 104r, and the data from the effective scanning data forming circuit C is written to both storage sections Ml and Mr at the same time.

Since either the "H" or "L" signal is output from the carriage traveling direction detection switch part e1, one of the above-mentioned angle gates 1-108° 110 is opened. Therefore, both memory sections Mll
, Mr is input to the waveform processing circuit WP.

However, since the operation of the clear button CB is performed with the carriage Y placed outside the effective needle selection range as described above, the electromagnets 46 of the knitting needle selection mechanisms Fl and Fr mentioned above are operated by the above-mentioned read data. It doesn't work depending on.

Even if the carriage Y is placed within the effective needle selection range by mistake, because the carriage Y is stopped, or even if it is moving, the above-mentioned timing corresponding to the traveling timing of the carriage Y Since the timing of the timing pulse from the pulse generator H1 or Hr is different from the timing of the sampling pulse from the sampling sensor d, the electromagnet 46 operates based on the data input to the waveform processing circuit WP. It never happens.

Next, the read address designation circuit RA will be explained. It inputs the output from the "1" output terminal of the up/down counter 112 as its output to the memory control circuit MC as described above.
Internal circuits other than this up/down counter 112 function as a count control circuit that controls the counting operation of the counter 112.

Now, the timing pulses from the timing pulse generators Hl and Hr (Fig. 23 [I]) are input to the effective timing pulse forming circuit 113, and only when the carriage Y is within the effective needle selection range and when the carriage Y is on the left. The effective timing pulse forming circuit 1 is divided into row and right rows.
13, it is taken out as valid.

That is, in addition to the timing pulse (1), the effective timing pulse forming circuit 113 receives a signal (
23 (V')) and a signal (VI) from the comparator circuit CO corresponding to the traveling direction of the carriage Y,
By detecting the falling edge of the timing pulse, only while there is a signal representing the effective needle selection range, in response to the signal (VI) representing the carriage running direction, when it is rHJ, [as shown in ” from the output terminal of
When it is LJ, an effective timing pulse is output from the output terminal "2", and the effective timing pulse output from the output terminal "1" is added by the up/down counter 112, and the output terminal "2" is added to the effective timing pulse output from the output terminal "1". The valid timing pulses output from the output signal are subtracted.

In this way, the effective timing pulses from the effective timing pulse forming circuit 113 are determined to be added or subtracted depending on the running direction of the carriage Y, but when the up/down counter 112 performs an adding operation, (For example, when the carriage Y is in the right row), it is reset the moment the carriage Y enters the effective needle selection range (from the left side), and from then on, as the carriage Y moves, the needle selection unit number setting circuit NS is reset. Each time a specified number is counted (added), it is reset and the specified number is counted repeatedly, and when the carriage Y leaves the effective needle selection range, the counted value at that time is is translated into the counted value storage memory 114. However, when performing a subtraction operation (for example, when carriage Y is in the left row), the up/down counter 112 indicates that carriage Y is the effective needle selection. The moment it enters the range (from the right side), the counted value storage memory 114 is preset to the stored counted value, and from then on, as the carriage Y moves, it is subtracted and when it reaches O, the needle selection is performed. Unit number setting circuit NS
The number is preset to the number specified by NS, and when it is subtracted from there and becomes 0 again, it is preset to the number specified by the needle selection unit number setting circuit NS, and the operation of subtracting from there is repeated. As a result, the up/down counter 112 takes the same count value for each knitting needle in the group of knitting needles within the effective needle selection range when the carriage Y is on the left row and when it is on the right row. It has become.

Now, to explain in detail the configuration that causes the up/down counter 112 to perform such an operation, the data selector 115 consisting of a gate network receives an output (parallel binary signal) representing the number of needle selection units from the needle selection unit number setting circuit NS. , the output (parallel binary signal) from the count value storage memory 114, which one is to be input to the up/down counter 112, and the preset instruction circuit 116 issues a preset instruction to the up/down counter 112. When the up/down counter 112 receives the preset instruction signal,
It is preset to one of the values selected by the data selector 115 (the number of needle selection units or the value stored in the memory 114).

The data selection instruction circuit 117 always outputs rHJ as shown in FIG. When the signal (V) representing the range rises (when the carriage Y enters the effective needle selection range), the rising edge is detected and a negative pulse is output, which is applied to the data selector 115 and preset instruction circuit 116. It looks like this.

The counter reset circuit 118 is a needle selection unit number setting circuit N.
When the input from S, that is, the number of needle selection units, and the input from up-down counter 112, that is, the counted value, match,
And when the input from the comparator circuit CO is "H" and the signal (V) representing the effective needle selection range rises, a reset pulse is output as shown in [■], thereby increasing and decreasing the The counter 112 is reset.

However, now the left and right switch activation pieces 31.3 are placed on the needle bed
If only one set of r is arranged and the carriage Y is in the right row and the output of the comparison circuit CO is rHJ when in the right row, the output of the data select instruction circuit 117 is "
H-1, the data selector 115 passes the input from the needle selection unit number setting circuit NS, but when the carriage Y is traveling outside the effective needle selection range, the data selector 115 passes the input from the needle selection unit number setting circuit NS. By setting the output of the data select instruction circuit 117 inputted to rHJ and supplying a borrow signal to the preset instruction circuit 116 when the up/down counter 112 is in the addition operation mode, the output of the 16th preset instruction is rHJ. The up/down counter 112 is not given a preset instruction.

When the carriage Y enters the effective needle selection range, the signal [■] representing the effective needle selection range rises at that moment.
The counter reset circuit 118 outputs a reset pulse, and the up/down counter 112 takes a value of 0.

When the carriage Y moves further to the right after entering the effective needle selection range, the up/down counter 112 adds the effective timing pulse □ from the output terminal "1" of the effective timing pulse forming circuit 113, and calculates the total value. The numerical value is the number of needle selection units specified by the needle selection unit number setting circuit NS (this is set as n)
If it matches, the counter reset circuit 118 is activated at that moment.
As a result, a reset pulse is output and the counter 112 is instantly reset.

Therefore, the counter 112 shows the count value "n" only for a short time, and the count value actually changes from "n-1" to rOJ. Therefore, the counter 112 At the time of addition, it can be regarded as an n-ary counter that counts from "O" to "n-1", and this counting operation is repeated while the carriage Y moves to the right within the effective needle selection range.

When the carriage Y leaves the effective needle selection range, the signal N representing the effective needle selection range changes from "H" to rLJ at that moment.
The effective timing pulse forming circuit 113 no longer outputs pulses.

Even if the carriage Y continues to move to the right thereafter, the counter reset circuit 118 does not output a reset pulse, and the valid timing pulse forming circuit 113 also does not output a pulse, so the up/down counter 1
12, the count value at the time of exit is held as is.

Note that the counted value at this time is stored in the counted value storage memory 114, but if the left and right switch activation pieces 311, 3r are one set, there is no substantial impact on other circuits. Since it has no effect, we will ignore it.

Next, when the carriage Y is reversed and moves to the left, the comparator circuit C
Since the output of O becomes rLJ, the effective timing pulse forming circuit 113 outputs a pulse from the output terminal "2",
As a result, the up/down counter 112 starts subtracting the count value when the carriage Y moves to the left from when the carriage Y enters the effective needle selection range.

When the count value becomes "0" as a result of such subtraction, the up/down counter 112 outputs a borrow signal, which causes the preset instruction circuit 116 to give a preset instruction signal to the counter 112, and the counter 112 is selected by the data selector 115. Preset to numeric value.

This preset is "n-IJ" designated by the needle selection unit number setting circuit NS because the output of the data selection instruction circuit 117 is "H".

Therefore, the up/down counter 112 changes its count value to "n-1" by the pulse input after counting "O".
and then perform subtraction for each pulse input to obtain IOJ
After counting, the same thing as above is repeated again.

In the above, the left and right switch activation pieces 3d.

We have described the case where only one set of 3r is placed on the needle bed
Even if a plurality of blocks are arranged intermittently on a plurality of sets of needle beds X, that is, even if a plurality of effective needle selection ranges are provided, similar unit pattern knitting can be performed for the effective needle selection range of each block. This is possible, and such a configuration will be described next.

Note that this configuration allows knitting fabrics in which similar patterns appear horizontally and horizontally, and in the following explanation, one effective needle selection sectioned by a pair of left and right switch activation pieces 31, 3r will be used. The range will be referred to as one point.

Therefore, if this method of expression is adopted, all the matters described above are the configuration and operation in the case of one-point knitting, and the matters described below are the configuration and operation in the case of multi-point knitting.

Now, the shift pulse generating circuit 119 is composed of, for example, a differentiating circuit, and detects the falling edge of the signal representing the effective needle selection range (Fig. 23 [V]), and the carriage Y is activated as shown in [X]. When exiting the needle selection range, that is, every time the needle exits each point, it outputs a signal rLJ and inputs it as a shift pulse to the memory 114 for storing counted values, and the memory 114 can be shifted left and right, for example. It is composed of a reversible shift register, and the shift direction is determined depending on whether the output (VI) of the comparator circuit CO is fTHJ or rLJ.

That is, the shift direction of the memory 114 changes depending on the traveling direction of the carriage Y.

When the carriage Y is in the right row, the up/down counter 112 performs the same addition for each point as shown in [W] in the same manner as in the case of the number of points being 1, as shown in [W]. The count values at the time of extraction are sequentially stored in the memory 114 by the shift pulse generation circuit 119 outputting a shift pulse each time.

Incidentally, in FIG. 23 W], they are "8" and "2".

Note that the memory 114 stores the count value as described above using the shift pulse, and also stores the stored data.
The evening signal continues to be output from that output terminal until the next shift is performed.

Next, when the carriage Y leaves the rightmost point and reverses and moves to the left, the memory 114 stores a parallel binary signal related to the count value when it leaves the rightmost point. Therefore, when the carriage Y enters the first point (the rightmost point above) and the data select instruction circuit 117 outputs a pulse (to), this pulse is sent to the preset instruction circuit 116 and data selector 115. As a result, the up/down counter 112 is preset to the value currently output by the memory 114, that is, the same value as the count value when the carriage Y moves past the point in the right row.

Note that the counter 112 holds the last counted value before reversal, as in the case of 1-point knitting described above, but since the counted value and the preset value are the same, There is no problem.

In the continuing left row of the carriage Y after the above-mentioned presetting, the counter 112 performs the same subtraction as in the case of the one-point knitting described above, and when the carriage Y leaves the rightmost point, the shift pulse generation circuit 11
9 outputs the shift pulse cause, the memory 11
4 outputs the numerical value related to the next (second from the right) point, and when the carriage Y enters that point, the counter 112 outputs the numerical value related to the next (second from the right) point. When the point is removed, it is preset to the same value as the count value when the point is removed, and then subtraction is performed as the carriage Y moves to the left.

Therefore, if the carriage Y is repeatedly moved left and right between the points beyond the end points on the left and right sides, for a certain knitting needle N within a certain point, data at a certain fixed address in the memory MEM will be read out. It is.

Therefore, if the left and right switch activation pieces 31, 3r are arranged on a plurality of sets of needle beds The pattern appears intermittently,
The number of patterns that appear intermittently can be set arbitrarily by changing the number of pairs of left and right switch activation pieces 31, 3r, and the width of each pattern is determined by the interval between each pair of left and right switch activation pieces 31, 3r. As mentioned above, the width can be set arbitrarily by changing the width, and the position of each pattern on the knitted fabric can also be set arbitrarily by changing the position of the left and right switch activation pieces 31, 3r of each set on the needle bed X. It's more obvious.

By the way, when performing multi-point knitting as described above, the transfer of the card 1 and the running of the scanning member are such that when the carriage Y approaches the switch activation piece 31 on the left side of the left end point, it moves to the right side of the right end point. This is done only when the switch activating piece 3r is approached, and this will be explained next with reference to FIGS. 14 and 18.

As mentioned above, the point number setting means 100 is configured to set the number of points, that is, the pair of left and right switch activation pieces 31, 3.
The set value is manually set according to the number of sets of r, and the set value is converted into a parallel binary electric signal by the encoder 100', and this signal is input to the comparison circuit 101 mentioned above. There is.

On the other hand, the signal representing the effective needle selection range (Fig. 18 [■]) from the above-mentioned effective needle selection instruction switch part e3 is output from the counter 1.
02, and the count value of the counter 102 (
ml') and the parallel output from the encoder 100' match, the comparator circuit 101 outputs (IV
) It is designed to output pulses as shown in the figure.

Further, the reversal of the signal CI representing the carriage running direction from the carriage running direction detection switch section e1 is detected by a carriage reversal detection circuit 103 including a knot, two differentiating circuits, and a Noah, and the detection circuit 103
The output pulse (V) of the comparator circuit 101 and the output pulse (IV) of the comparison circuit 101 are added to the AND 103', and the counter 102 is reset by the output (Vl) of the AND 103'.

Therefore, when the carriage Y is in the left row and when the carriage Y is in the right row, the comparator circuit 101 calculates the comparator circuit 101 when the carriage Y passes the next point. A pulse is output when the switch mechanism Gl approaches the switch activation piece 31 on the left side of the left end point, and when it approaches the switch activation piece 3r on the right side of the right end point when the carriage Y is in the right row. As described above, the pulse passes through the OR 82, is inverted at the knot 82', and is input to the card feeding and scanning control circuit SC as a card feeding and scanning instruction signal. The movement of the scanning member and the transfer of the card 1 are carried out during the extra reversal movement outside the left and right points of the carriage Y, as in the case of one point described above.

In addition, in FIG. 14, the card feeding and scanning control circuit S
If C is configured such that the scanning member drive circuit SD is operated after the operation of the card feeding drive circuit CD, the card is first fed and then the scanning member is moved.

Although one embodiment of a hand knitting machine to which the present invention is applied has been described above, the present invention is not limited to this.

That is, in the above embodiment, the switch activation pieces 31, 3 that partition the effective needle selection range serve as point setting means.
r are separately placed on the needle bed X, and when the carriage Y approaches them, the switch mechanism G7. Gr.
The automatic movement of the scanning member N and the automatic transfer of the card 1 are carried out by detecting the needle N at a specific position. It may also be configured to travel and be automatically transferred.

FIGS. 26 and 27 show an embodiment of the present invention, in which the carriage Y is provided with a point detection means for resting knitting needles on both the left and right sides of the base plate 4, in addition to the needle selection end detection switch mechanisms Gl and Gr. A detection switch mechanism J (the one on the left is not shown) is provided.

This switch mechanism J is provided with a switch 121 on the lower side of a sensing plate 120 whose base end is rotatably supported on the base plate 4, and a downwardly bent portion 120' which is a free end of the sensing plate 120.
The lowermost horizontal portion of the downwardly bent portion 120' of the bed plate 4 is positioned further below the head end of the butt N' of the knitting needle N at the rear rest position. When the knitting needles N are in the rear rest position, the sensing plate 120 is lifted up by the needles l-N' and the switch is activated. When the switch 121 is turned off and the knitting needle N is at a position other than the rear rest position, the sensing plate 120 holds the switch 121 in the on state.

The horizontal portion of the downwardly bent portion 120' of the sensing plate 120 is located on the rear extension line of the sorting point of the knitting needle sorting mechanism F7 or Fr.

Therefore, the carriage Y is connected to the knitting needle selection mechanism Fl or F.
The switch 105 is switched from the on state to the off state when the first of the knitting needles at the rear rest position is reached from the knitting needle group set at the needle selection receiving position which is subjected to the sorting action by r. 14th by signal
By controlling the card feeding and scanning instruction circuit C8 shown in the figure, the card 1 can be automatically transferred after the scanning member is automatically moved in the same manner as in the case described above.

In addition, in the above, the needle selection end detection switch mechanism GA
, Gr and the switch mechanism J for detecting resting knitting needles on the carriage Y
Although these are provided on the carriage Y, it is clear that the same operation as described above can be performed even if they are provided on a member that moves integrally with the carriage Y.

Further, in the above embodiment, the left and right switch activation pieces 31, 3r are arranged on the needle bed X as point setting means for dividing the needle selection range, while the switch activation pieces 3A and 3r are disposed on the carriage Y as point detection means. The machine is equipped with mechanical needle selection end detection switch mechanisms Gl and Gr that operate as switches when engaged with 3r, but as a point setting means, a member with an optical mark is placed on the needle bed X, This may be detected by a photoelectric sensor as a point detection means provided on the carriage Y side, or a reed switch is installed on a guide rod or the like installed horizontally on the knitting machine body X side as a point setting means so as to be able to slide left and right. Even if the carriage Y is equipped with a permanent magnet so that the reed switch operates when the carriage Y approaches the reed switch, electrical detection of the left and right ends of the effective needle selection range can be performed. It is something.

Further, in the above embodiment, the coil 31 of the scanning member
is fitted into the guide rod 28, and by passing currents of opposite polarities through it, the permanent magnet 32 is used as a stator to apply magnetic forces in opposite directions to the left and right coils 31, thereby causing the scanning member to reciprocate. However, there are two coils whose winding directions are reversed.
Moreover, even if the guide rod 28 is made of a magnetic material and current is passed through the two coils alternately so that a magnetic force is generated between the coil and the guide rod 28, the scanning member can be moved back and forth. It is something that can be run.

In this case, the guide rod 28 functions as a guide means for guiding the movement of the scanning member, and at the same time functions as a stator of the linear motor.

Furthermore, although the card 1 is driven by the electromagnets 16 and 16' in the above description, a pulse motor may also be used instead.

Furthermore, in the above, a card in which one entry grid corresponds to one stitch was used as the knitting program card 1, but a card in which one entry grid corresponds to a predetermined plurality of stitches may also be used. A card on which a pattern, a function mark, and a needle selection unit number setting mark are printed in advance may be used.

Furthermore, the knitting pattern and the above marks can be created by filling in the card surface, or by pasting colored paper of the desired shape onto the card, and can be read in the same way as above. It is.

As is clear from the above description, the knitting information reading method of the present invention involves loading a knitting information recording medium (knitting program card 1 in the embodiment) for recording information such as a knitting pattern representing a pattern to be knitted. a recording medium transport mechanism capable of transporting the composition information recording medium in a desired direction in a loaded state; a scanning member capable of reading the information recorded on the composition information recording medium as an electrical signal; In a knitting machine equipped with a traveling drive mechanism capable of automatically traveling along a line orthogonal to the transport direction of the knitting information recording medium, a point setting means (a switch in the embodiment) is provided at any left or right position on the knitting machine side. Starting pieces 31, 3r or knitting needles N) are arranged, and one of a pair of left and right specific members (left and right knitting needle selection mechanisms Fl!, Fr or timing pulse generators Hl, Hr) provided on the left and right sides of the carriage. , one member that operates effectively in relation to the traveling direction of the carriage receives a predetermined electrical signal when it moves from within the range defined by the left and right point setting means to outside the range as the carriage travels; At least the scanning member is automatically run by effectively operating the recording medium transport mechanism and the running drive mechanism by an electric signal, and the scanning member is automatically run in conjunction with the carriage running. This makes it possible to read the information on the recording medium and perform the needle selection operation based on the information extremely efficiently, and also allows the scanning member to automatically travel while the carriage is running excessively. The above reading can be performed efficiently.

Furthermore, in the present invention as set forth in claim 2, the recording medium is transferred after the scanning member scans.
Even if the carriage is quickly reversed in the extra travel range, the above-mentioned scanning can be carried out accurately, and there is no risk of erroneous formation due to the quick reversal of the carriage.
