Description

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, an information recording medium in which information such as a knitting pattern representing a pattern to be knitted is recorded is removably supported on a recording medium support, and the recording medium support is rotated. The present invention relates to an information reading device for a knitting machine, which is equipped with a transfer mechanism that allows transfer.

Conventionally, this type of device uses an electromagnet as a drive source, and has a feed pawl on the plunger side and a ratchet wheel on the recording medium support side, and the electromagnet is energized and deenergized to move the plunger back and forth. The recording medium support can be rotated by intermittently engaging the feed pawl with the ratchet wheel and rotating the ratchet wheel step by step.
That is, it is known that an electromagnet and a recording medium support are linked via a ratchet mechanism (feed pawl and ratchet wheel) which is a linear motion/one-rotation motion conversion mechanism and also a step feed mechanism.

However, according to this method, the linear reciprocating motion of the electromagnetic plunger is converted into rotational motion, so the one-step forward motion inevitably becomes slow, and the information recording medium is continuously moved in several stages or several stages. It takes a long time to move 10 steps, and when an information recording medium is to be transferred in conjunction with a carriage operation, the carriage operation must be temporarily stopped and waited until the transfer is completed, which is extremely inconvenient. It is efficient, but if you try to increase the speed, you have to use a large electromagnet with a large output, which makes it uneconomical in terms of speed.

In addition, in this conventional device, in order to be able to automatically transport the information recording medium in either the forward or reverse direction, the above-mentioned feeding claws are provided with one for the forward direction and one for the reverse direction, and the user can select one of them. The disadvantage is that the configuration is extremely complex, such as having to operate manually.

Therefore, the present invention proposes an information reading device for a knitting machine that can automatically transfer an information recording medium at high speed in both forward and reverse directions with a simple configuration. There is a particular thing.

Further, the present invention allows the above-mentioned forward and reverse automatic transport direction of the information recording medium to be arbitrarily designated by information on the information recording medium or by operation of a manual operation member.

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 main body X having a needle bed The information reading device A of this embodiment is equipped with a scanning member (not shown in FIG. 1) that optically scans recorded information, and in addition to this reading device A, various mechanisms described later are manually operated. Control panel 2 contains manual controls used for
A control box B, which is installed above the needle bed and also has various electric and electronic circuits described later, is installed behind the needle bed X, and the needle selection range can be arbitrarily divided on the needle bed X. Left and right needle selection range setting switch activation pieces 31.3r, which are point setting means, 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 Although not shown in the figure, a row of knitting needles are placed on the needle bed X in response to an electrical signal obtained by scanning the knitting pattern on the knitting program card 1.
A pair of left and right knitting needle sorting mechanisms, one of which operates effectively for sorting forward and backward according to the direction of movement of the carriage Y using electromagnetic force, are arranged at a predetermined length apart on the left and right.

The reading device A has a scanning member mounted on a carriage Y.
(More specifically, when the carriage Y approaches the switch activation piece 31 or 3r)
By automatically scanning the recorded information horizontally and linearly, a corresponding electrical signal is output, and the subsequent processing of the electrical signal is now performed using an electronic configuration. Further, power is supplied to the electrical components of the pair of left and right knitting needle sorting mechanisms by a cord 6 that is passed through a tension member 5 that applies tension to the knitting yarn, and the carriage Y is connected to the switch activation piece. 31
, 3r, only the knitting needles within the interval range of the switch activation piece 31.3r are effectively sorted (even those within this range are in a rest position where they are not subjected to any sorting effect). (excluding things).

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 installed in a frame 7 further behind the rising wall x1 at the rear end of the needle bed To explain the transporting device, endless sprocket belts 81 and 8r, which serve as recording medium supports, are mounted on the left and right sides of the frame 7 so as to be able to circulate.

The sprocket bells) 81, 8r have sprockets 8/ that fit into the left and right perforations 1' of the knitting program card 1 protruding from the outer circumferential surface at a constant interval, and these left and right sprocket bells) 81 , 8r and a card guide plate 9 having a U-shaped cross section and arranged below between them, and fitting the perforation 1' into the sprocket key ( As a result, the sprocket belt 81.8r can support the card 1 in a U-shaped bent state, and in this supported state, the pulse motor a installed on the right side of the frame 7
By being circulated by the card 1, the card 1 can be transferred in the direction in which the perforations 1' are arranged.

That is, each sprocket belt 81, 8r has a lower dog pulley 101 t 10 r as shown in FIGS.
and the small boob 11°11r diagonally above it, and the left and right dog pulleys 101, 10r are drive shafts 12, and the left and right small boo! J111t11r are connected to each other by a rotating shaft 13, and furthermore, the driving shaft 1
2 is integrally connected to the shaft of the above-mentioned pulse motor a, and as the pulse motor a rotates, the left and right sprocket belts 81.8r circulate simultaneously.

Therefore, the pulse motor a is capable of forward and reverse rotation, and the forward and reverse direction of the drive shaft 12 is determined depending on whether the pulse motor a is driven forward or backward. (Bottom side of Figure 2) This determines whether to send in the opposite direction.

As mentioned above, the card 1 optically scans horizontally and in a straight line, and if there are any irregularities on the line to be scanned, the accuracy of reading the information recorded on the card 1 may be compromised. In order to prevent this, a card receiving plate 24 is provided between the left and right sprocket bells 81.8r, and furthermore, on the left and right of the left and right bells t'8L8r, the left and right of the card 1 is Left and right card holding pieces 251 that lightly press the side edges, respectively.
It is equipped with 25 r.

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.
Also, each card holding piece is 25I.

25r has a fulcrum on the axis of the drive shaft 12, as shown in the side view of the right side in FIG. However, the card 1 is urged rearward, that is, in the closing direction, by the spring 26, and the card 1 is pushed by the sprocket belt 81 across the left and right perborations 1', as described above.
．． Insert into the sprocket 81 of 8r and attach the card holding piece 251.
By pressing at t25r, 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 in this flat sloped 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 29° 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 therewith.

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 always crosses the magnetic field, and the traveling body 2 is moved by the magnetic force that moves during that time.
9. The cut scanning member automatically moves to the left or right along the guide rods 27 and 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 motor with 2 serving as a stator.

At positions corresponding to the left and right ends of the permanent magnet 32, as shown in FIG. 6 (cross section taken along the line ■-■ in FIG. 2), left and right limit switches 331 act to switch the polarity of the current flowing through the coil 31. .33r is placed.

The limit switch 331 on the left is turned on when the scanning member collides with the left row, and the right limit switch 33r is turned on when the scanning member collides with the right row. limit switch 3
It moves left and right between 31 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, which is its original position. , in relation to the reversal of carriage Y, it moves rightward from its original position at a considerable speed to the right stroke end, and as soon as it reaches the right stroke end, it immediately reverses (
The left and right limit switches 331 and 33r respectively check whether the scanning member is at the original position or the inverted position (right stroke). end)
It also functions as a means of detecting whether or not it is present.

As shown in FIG. 3, the upper extension 29' of the scanning member running body 29 extends obliquely upward on the rear side, and then extends obliquely downward, and its leading edge is on the inclined surface of the card receiving plate 24. It faces it at a close position, and at its tip is a so-called light-receiving element that consists of a reading element, that is, a light-emitting element, and a light-receiving element that receives reflected light that is reflected from the surface of the card and converts it into an electrical signal. A photoelectric sensor C 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. 2. It is translucent, and the perforations 1' on its left and right
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 organizing function information recording area on the right side, that is, the area where the function mark is recorded, is set to a color that is the same as the emission color of the light emitting element of the scanning sensor C and that the light receiving element does not discriminate (for example, the light emitting element is red). It is created by displaying the grid division lines (red when using light emitting diodes) 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, are arranged in a row on the perforation 1', for example, by placing a slightly thick horizontal black line in a row. It can be recorded in advance by displaying it at regular intervals in the direction.

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

In the above-mentioned knitting pattern entry field 1p, the vertical lines of the grid dividing lines that constitute it are the dividing lines between the stitches, and the horizontal lines are the dividing lines between the knitting rows, and below the outside of the field, The numbers representing the stitches are displayed in the same color as the grid dividing lines.

To be more specific, in the knitting pattern entry column 1p, one minimum section, that is, a lattice, corresponds to one stitch,
Its horizontal arrangement, or row, corresponds to one knitting needle, and its vertical arrangement, or row, corresponds to a knitting course (course), and n horizontal rows of stitches constitute one group. 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 the boundary line, and a picture (knitting pattern) corresponding to the unit pattern to be knitted is drawn between them. is drawn 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 range between the left edge vertical line and the 12th day's vertical line It is a thing that depicts a picture inside.

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 above-mentioned lattice one by one.

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

Furthermore, in the function mark entry field 1f, its horizontal line is on the same line as the horizontal line of the knitting pattern entry field 1p, and its 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 lattice on 1f are on the same line as those in the knitting pattern entry field 1p, and there are the same number of rows (horizontal arrangement), but the number of rows (horizontal arrangement) is, for example, 36 in the knitting pattern entry field 1p.
However, it is now 4.

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

Further, in this example, each of the feed control marks 34 displayed in advance on the left edge is located at the horizontal center of each row of the lattice in the knitting pattern entry field 1p. The card 1 is positioned on the line and the extension line, and as will be described later, the card 1 is automatically advanced to each stage of the grid.

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

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

In this example, the number of witness grids 35 is six in total, and the one on the left is the number of needle selection units "6", and is expressed as 112.18.24.30, 36J in hexadecimal.

This needle selection unit number setting field 1s is also scanned by the scanning sensor C of the scanning member, and its witness grid 35...
The number of needle selection units is determined by which witness grid is marked.

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 witness grid 35 in the setting field 1s, and its position on the card 1 is the witness grid 35...
. . . on the extension line in the row direction and directly below the feed control mark 34 .
It is longer on the right side than that of . It has become.

Then, when the card 1 is loaded in the left and right sprocket bells 81.8r as described above and 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 a scanning sensor C, and the scanning member is automatically transferred according to the feed control mark 34 only when it is in its original position. , and the card 1 is in the inverted position (
When the stroke end on the right side is reached, the witness grid row on the right side of the function mark entry field 1f can be read, and the range between these two reading positions can be read while the scanning member is traveling. It is designed to be used.

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

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 the knitting pattern horizontally and linearly for each row of drawn grids. The electrical signal related to step scanning is the first
As shown in Figure 2 ■ (an example when card 1 is scanned along the p2 P2 line in the same figure), a square wave is generated according to the pattern of the knitting pattern in one stage of the filled grid, that is, the pattern of one horizontal scanning of the knitting pattern. If this is the only electrical signal obtained by scanning, there is no one-to-one correspondence with the knitting needle to be selected, and the function mark entered in the function mark entry field 1f also does not correspond to the knitting needle to be selected. , is read by the scanning sensor C in the same way as the above-mentioned knitting pattern, and becomes an electric signal in the same electrical system as in that case, and furthermore, the search mark 36 that is displayed in advance is also read in the same way and the same These three types of electrical signals are separated from each other in the electrical system, and the electrical signals related to reading the knitting pattern are separated from the knitting needles.
It is converted into a corresponding digital electric signal in a one-to-one relationship, and the electric signal related to reading the function mark is also separated for each witness grid row (vertical row) in the function mark entry field 1f. The mechanical structure of the sampling mechanism that performs this operation, that is, the sampling operation, will be explained with reference to FIGS. 2 and 3.

The frame 7 is located behind the running body 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, the linear encoder 37 uses the feed control mark 34 on the card 1.
One search mark sampling slit 38s is bored at a position corresponding to the blank space between ... and the knitting pattern entry field 1p, and on the right side of the slit 38s, a drawing is made in the knitting pattern entry field 1p. A predetermined number (120 in this example) of knitting pattern sampling slits 38p for sampling the knitting patterns
......, from the position corresponding to the witness grid row at the left end of the knitting pattern entry field 1p, to the right in a straight line at regular intervals beyond the right edge of the entry field 1p. Further, on the right side, a predetermined number (four in this example) of function mark sampling slits 38f°°°°°°°° are arranged in a row to sample the function marks. The holes are drilled in one-to-one correspondence with each witness grid row in the entry field 1f.

On the other hand, on the rear side of the scanning member running body 29, there is a photoelectric sensor for optically reading the three types of slits 38s, 38pt, and 38f, that is, a light emitter that illuminates the front surface of the linear encoder 37. A sampling sensor d consisting of a light receiving element and a light receiving element that receives the reflected light is attached.

As the scanning member s travels, the sampling sensor d is moved to 38s, 38p...
......, 38f... outputs a pulse, that is, a sampling pulse, according to the song... river..., and the sampling pulse is different from the electric signal related to the scanning of the scanning sensor C mentioned above. Similarly, as will be described later, only the movement process of the reciprocating movement of the scanning member is taken out as the effective one as shown in Fig. The sampling pulses, that is, one sampling pulse for sampling the search mark 36, 120 sampling pulses for sampling the knitting pattern, and 4 sampling pulses for sampling the function mark are mutually exclusive. It is designed to be separated.

By the way, when sampling the knitting pattern, the number of rows (horizontal arrangement) of the witness grid in the knitting pattern entry field 1p was set to 36 to obtain 120 sampling pulses. This is to make it possible to apply, in addition to the above-mentioned card 1, a card (FIG. 19) in which the number of rows is "120" (as described later).

Therefore, for card 1 whose number of columns is "36",
Surin per entry grid in knitting pattern entry field 1p)
By corresponding three 38p each, the input grid 1
Three sampling pulses are changed for each scan, but as will be described later, when organizing cards 1 with 36 rows, the above three sampling pulses are changed as shown in Figure 12 Two of the pulses are removed, and the remaining one sampling pulse samples the electrical signal associated with the scanning of one grating.

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 Figure 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 3.7 to 3.
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. In contrast to storing data in memory sequentially from left to right,
The actual needle selection operation, which is performed by reading out the digital electric signal stored in the memory, is performed during both the reciprocating strokes of the carriage Y, with the left and right knitting needle selection mechanisms operating alternately according to the traveling direction of the carriage Y. Therefore, in order to knit a pattern according to the knitting pattern drawn on card 1, it is necessary to detect the traveling direction of the carriage Y and control the storage and reading of digital electrical signals in the memory according to the detected signal. Must be.

Therefore, the rear side of the carriage Y is shown in Fig. 7 (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 Fig. 8. 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 shaft frame 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 shaft frame 39, between two front and rear magnetic plates 43□, 43□. The two magnetic plates 431 and 432 are magnetic.
The lower end of the horizontal hole 4I provided in the base plate 4 and the base plate 4
The lower end surface of the magnetic plates 431, 43□0 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, a microswitch e having three switch parts e1 to e3 is fixedly installed on the rear side of the shaft frame 39, and a lever e/ of the switch e is installed on the rear wall of the shaft frame 39. The magnetic plate 432 is inserted into the hole 43' of the magnetic plate 432 on the rear side by passing through the window hole.

Thus, the switch actuator 40 is fitted into the shaft frame 39 so as to be able to slide freely within a predetermined range on the left and right, and is attracted to the carriage guide bar 45, thereby allowing the carriage Y to move freely. When moving the carriage Y to the left, it slides to the right sliding limit position against the shaft frame 39 and then moves with it, and when moving the carriage Y to the right, contrary to the above, it slides to the left sliding limit position. After being moved, 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 operates to move one of the microswitches, that is, the carriage. From the switch part e1 for detecting the running direction, Figure 15 ■ or 1
As shown in Figure 7■, by reversing the running of carriage Y,
'' to rLJ or vice versa.

Next, the left and right knitting needle selection mechanisms Fl and Fr, which ultimately select the front and back of the knitting needles N, will be explained with reference to Figs. 3 and 7゜9. 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 are each made of magnetic material and are made of one piece.
One ends of the pair of magnetic conductors 47 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 49 □ that is long from side to side on its lower surface, and in the bat passage 491,
The butt N of the knitting needle N set at the needle selection receiving position can be received through the side cam 50.

The inside of the front diameter of the Konohatsu passage 4910 is almost the same as that of the bat NI, and its upper wall surface is a tapered surface where the outer half 492 on the outside as seen from the carriage Y descends inward, as shown in FIG. Inner half 493 is separated) N
The horizontal plane is slightly lower than the steady height of /.

Therefore, in the process of passing through this bat passage 49, the bat N' is pushed toward the leaf spring 5 from the middle of the outer half portion 492.
1 (Fig. 3) and is gradually pushed down, and the inner half 4
93, and passes through the butt passage 49□ in a tightly 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 491, and the lower surface of the horizontal part faces the inner end of the bat passage 491.
This is a continuous surface that is flush with the inner half 493 of the soil wall surface of No. 1.

Further, the other magnetic conductor 48 has a notch 48 halfway from the upper side in a vertical portion below the carriage base plate 4, and an outer vertical portion 482 outside the notch 48□ is provided with the above-mentioned cutout 48 Although the magnetism from the electromagnet 46 acts, it hardly acts on the inner vertical portion 483 on the inside.

The magnetic conductor 48 has its outer vertical portion 48□ along the rear wall surface of the bat passage 49, and the bat passage 49,
At the same time, the vertical front surface extending from the outer vertical part 482 to the inner vertical part 483 faces inward from the inner end (bat outlet) of the bat passage 49□, as shown in FIG. The surface slopes backward.

In addition, the right and left middle of the outer vertical portion 482 of the magnetic conductor 48 is a little shorter than the arranged pinch of the knitting needle N, and the outer vertical portion 48 The rear surface is brought into pressure contact with the vertical front surface of □, and the head end is brought into pressure contact with the horizontal lower surface of the other magnetic conductor 47, and the inner vertical portion 483 of the magnetic conductor 48
A gap passage 51 (seventh
Figure) is formed.

Therefore, the knitting needles N having the batt NI fitted into the batt passage 491 are selected in the following manner.

As the carriage Y travels, the bat N' that has entered the bat passage 49 is gradually pushed down while its back and forth movement is restrained, and is brought into pressure contact with the horizontal lower surface of one of the magnetic conductors 47. 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
Different magnetic poles are excited in the outer vertical portion 48□ of the magnetic conductor 48, and a kind of magnetic path is formed between them through the butt N', and the outer vertical portion 48□ of the magnetic conductor 48 is excited. is inclined rearward, the butt attachment is slightly attracted and biased rearward along its outer vertical portion 48 □ and deviates from the horizontal lower surface of the magnetic conductor 47 and enters the gap passage 51 .
It 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 482 (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 part 48□ of the magnetic conductor 48, and is pushed down by the horizontal part of the magnetic conductor 47 after passing through the bat passage 491. The beam also travels straight, rises to a steady height beyond the inner edge of the horizontal portion, and then passes through a forward guide path different from that in the case of excitation.

The left and right knitting needle sorting mechanisms F l + F r should be effectively operated by switching the electromagnet changeover switch section e2 in the microswitch e of the carriage reversal switch mechanism E according to the traveling direction of the carriage Y. Only one 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-mentioned configurations, and the knitting needles N with the butt N' fitted into the butt passage 49 However, 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 de-energized state, it is not subjected to the above-mentioned sorting action by the electromagnet 46. The configuration will be explained with reference to FIGS. 7 and 8.

The left and right switch activation pieces 31 and 3r both have a cam groove 31 running left and right on their upper surfaces, and also have a plurality of protrusions 3□ protruding from the front end of their lower surfaces that fit into the needle groove x2 from above. A plurality of butt-engaging grooves 33 are formed on the side surface to tightly receive the butt N' of the knitting needle N, and both of the butt-engaging grooves 33 fit the protrusions 3□ into the rear ends of the needle grooves 33, by engaging the butt N/ in the needle bed X, it can be placed at any position on the needle bed X without moving left or right. The relationship is

That is, the left switch activation piece 31 is connected to the cam groove 3□0.
The arrangement of the front and rear cam parts 34 and 35 forming the front and rear side walls is in a relationship such that the front side is on the left and the rear side is on the right, whereas that of the right switch activation piece 3r is in the opposite relationship to the above. It has become.

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 31 and 3r as the carriage Y runs. It is equipped with Gr.

The left and right switch mechanisms Gl 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.
It is pivoted horizontally rotatably on the top of the carriage base plate 4, and has a protrusion 55 projecting downward from the lower surface of one end thereof through the window hole l of the carriage base plate 4, and the other end thereof is connected to the lever of a microswitch 56 mounted on the base plate 4, and as the carriage Y travels, the protrusion 55 passes through the cam groove 3□ of the left or right switch activation piece 31, 3r. , the crank 53 rotates to switch the microswitch 56.

That is, the microswitches 56 and 56 of the left and right switch mechanisms Gl and Gr are both on when their corresponding protrusions 55 and 55 are both within the interval between the left and right switch activation pieces 31 and 3r, and when outside this interval It turns off when you exit to: (S).

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 Gl t G r is switched when the sorting point of the left and right knitting needle sorting mechanisms Fl + Fr approaches the installation position of the switch activation piece 31°3r on the needle bed X, as shown in Fig. 17 ■ and ■, respectively. As shown in FIG. The effective needle selection range indicating switch section e3 allows only the needle on the side where effective needle selection is to be performed to be taken out.

Therefore, as shown in Fig. 17 (■), the effective needle selection range indicating switch section e3 is configured to detect the effective needle selection range from when the needle selection end detection switch mechanism Gl or Gr on the side that performs the effective needle selection operation is turned on until it is turned off. 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 31.3r, a signal rHJ indicating the effective needle selection range is output. , outputs the signal rLJ when the distance is outside the above interval range, and while the above rHJ is being output, the aforementioned memory that stores the digital electrical signals related to the knitting pattern is read out, and the effective needle selection operation is performed only during that time. The electromagnet 46 on the side is controlled to be energized or de-energized.

In this way, reading of the memory is performed only within the effective needle selection range determined by the left and right switch activation pieces 31, 3r, but the reading is performed because the traveling speed of the carriage Y is not constant and varies greatly. , must be done in accordance with the timing of carriage Y travel.

Therefore, the carriage Y is provided with a photoelectric sensor H1 at the rear end on the base plate 4 at positions corresponding to the left and right knitting needle sorting mechanisms Fl and Fr, respectively.

Hr is installed, and its photoelectric sensor H1°Hr
However, on the rising wall X1 at the rear end of the needle bed X, there is a needle groove X.
The slits x3, which are arranged in a one-to-one relationship, are used as a kind of linear encoder. The photoelectric sensors H1 and Hr are read as the carriage Y moves.
As shown in FIG. 17I, a pulse, that is, a timing pulse, is output in accordance with the traveling timing of the carriage Y, and this timing pulse controls the reading of the aforementioned memory. Let us call the photoelectric sensors H1 and Hr a timing pulse generator.

It should be noted that the pulses from the left and right timing pulse generators H1 and Hr are taken out as valid only by the carriage reversing switch mechanism E that corresponds to the needle selection mechanism F1 or Fr on the side that performs the effective needle selection operation. 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,
The configuration of the input function section that stores the read knitting pattern as a digital electric signal in the memory MEM will be explained with reference to FIG. 10.

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. It is taken out as a card feeding and scanning instruction circuit C8, a needle selection unit number setting circuit NS, a memory control circuit MC, and a function discrimination circuit FS.

The card feeding and scanning instruction circuit C8 receives an electric signal when the left limit switch 331, which is a scanning member original position detection means, is turned on. Only when the card 1 is in the position, it is determined whether the electric signal from the effective scanning data forming circuit C is rHJ or "L", that is, whether the display on the card 1 is a mark or no mark. An electric signal corresponding to the determination result is supplied to the card feeding and scanning control circuit SC, and the control circuit SC thereby controls the motor drive circuit CD according to the mark or no mark to drive the pulse motor for card feeding. a
is driven, thereby causing the card 1 to display the search mark 36, feed control mark 34, etc.
The data is automatically transferred at intervals of .

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.
When the needle enters from outside the effective needle selection range divided by the left and right switch activation pieces 31 and 3r, an instruction signal for starting the scanning member to travel is input to the control circuit SC. Furthermore, the control circuit SC is configured to receive an electric signal when the right limit switch 33r, which is a scanning member reversal position retrieval means, is turned on, thereby causing the control circuit SC to operate as a scanning member drive circuit. SD is controlled so that the drive circuit SD also supplies sufficient current to the coil 31 of the scanning member 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 pulses before thinning for sampling the knitting pattern from the pulse separation circuit PS, and in which number of pulses the effective scanning data forming circuit C selects the number of needle selection units setting column 1s. Depending on whether an electrical signal related to reading the mark is input, the number of needle selection units programmed in the needle selection unit number setting field 1s is memorized using a digital electrical signal, that is, the number of needle selection units is electrically preset. There is.

Then, the needle selection unit number setting circuit MS determines whether or not to thin out pulses for sampling the above-mentioned configuration 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 P
Further, this setting circuit NS controls the card feeding and scanning instruction circuit C by receiving an instruction to electrically preset the number of needle selection units as described above.
8 and the card feed and scanning control circuit SC, the scanning member swivel scans the needle selection unit number setting field 1s once and returns to its original position, and then the card 1 is moved to the scanning member slit feed control mark. 34............ until the bottom mark is read.

The write address designation circuit WA includes a binary counter that counts the pulses inputted 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 as an address designation signal. It is now entered as .

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.
An electric signal corresponding to the carriage running direction from the carriage running direction detecting switch section e1 is sent to a certain fixed address of the EM, and the carriage Y is scanned in the left-hand direction and in the right-hand direction. The information is stored separately in separate storage units, that is, in two storage units.

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 witness grid row, and the sampling of the two columns on the left side of the witness grid row is inputted to the card feeding and scanning control circuit SC, and the card 1 is sent to it 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 specific configuration of the effective scanning data forming circuit C1, effective sampling pulse forming circuit D, pulse separating circuit PS, needle selection unit number setting circuit NS, and function discrimination circuit FS will be explained with reference to FIGS. 11 and 12. .

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. The AND gates 61C and 61d are opened only during the working process of traveling from to the reversing position, and only during this time the output signal of the scanning sensor C and the output signal of the sampling sensor d form effective scanning data. It is designed to be outputted from an AND gate 61ct61d as an output signal of the circuit C1 effective sampling pulse forming circuit (see FIG. 12 V, IX, and I).

As shown in FIG. 12, the output of the limit switch 331 is rLJ when the scanning member is in the original position, and becomes rHJ when the scanning member moves away from the original position. An R-S flip-flop 62 is set when the scanning member leaves the original position to separate the first pulse from the effective sampling pulse forming circuit (for sampling the search mark 36). It is reset by the falling edge of the pulse).

The Q output of this flip-flop 62 opens the AND gate 63 which receives the pulse from the effective sampling pulse forming circuit. The pulses other than the pulses for sampling the function 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 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 needle selection unit number setting field 1s. When scanning across the twelfth surface (scanning along the p1-p1 line on the 12th surface, V in the figure is the output waveform of the effective scanning data forming circuit C at that time), the search mark sampling slit of the sampling sensor d linear encoder 37 When 38 seconds is detected, one pulse is output as shown in (■).

Therefore, this pulse output from the AND 64 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 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 are input to the AND 66. As is clear from the comparison of m, rv, v, and ■ in FIG. 12, when the outputs of are all rHJ, that is, after the search mark 36 is detected as described above, the needle selection unit number setting field 1s is When the mark made on the wafer is detected, one pulse is output as shown in ①, and 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 (■) only until the mark in the needle selection unit number setting field 1s is detected.

Note that the above-mentioned one pulse also controls the above-mentioned card feeding and scanning instruction circuit C8 and the same control circuit SC as described later.

On the other hand, as mentioned above, the pulse ■ from the AND gate 63 from which the pulse for sampling the search mark 36 has been removed is sent to the hexadecimal-binary counter 67, specifically the pulse ■
The count value of the counter 67 increases by 1 every time 6 pulses are counted. It is progressing step by step.

The count value of this counter 67 is the output of the AND 66 above
When the mark in the needle selection unit number setting column 1s is detected by the gate network 68 which uses .

This memory 69 is designed to be reset at the rising edge of the output (2) of the flip-flop 65, that is, at the time of sampling the search mark 36.

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

This gate network 70 performs the above-mentioned discrimination on the parallel output from the counter 67 using a logic circuit formed by a combination of gates.
An output is generated from the output terminal ``2'' to open the AND gate 171, and if r121J or higher, an output is generated from the output terminal ``2'' to open the AND gate 712.

Therefore, the AND gate 71 outputs 120 pulses for sampling the knitting pattern as shown in ■, and the AND gate 71□ outputs 4 pulses for sampling the function mark as shown in ■. 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 shown in X■, and its "2" output system passing through T.
It includes a type flip-flop and an AND gate connected to this output side, and as shown in 3" output system includes a ternary counter and an AND gate connected to this output side, and as shown in XV, 3n-1 (
However, the pulses (n is an integer) are left and the others are thinned out.

On the other hand, the output of the memory 69 which stores the number of needle selection units programmed in the needle selection unit number setting field 1s in the card 1 as described above is the same as the above three types output from the pulse selection circuit 72. 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 the XV pulse of the three types of pulses is now passes through ora 75, and 42
~600, an output is generated from the output system of "2", the AND gate 74□ opens, and the pulse of An output is generated from the output system of ” and the AND gate 74
1 is opened, and the pulse of ■ is allowed to pass 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 lattice rows entered 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 the cards that can be selected as 0.36, as shown in FIG.
48, 54, and 60 cards, and as shown in Figure 19, the number of filled grid rows is 120 and the number of needle selection units is 66.
．． 72.78.84.90, 96.102.108.1
This is because a total of three cards that can be selected for 14.120 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 shown in FIG. The output of the valid scanning data forming circuit C (the scanning sensor C) is input to the control circuit MC and the write addressing circuit WA.
(in Figure 12, the output when card 1 is scanned along the p2 P2 line is shown in ■), and the output related to the scanning of knitting pattern entry field 1p is XV
After being converted into a digital electrical signal corresponding to the knitting needle in a one-to-one relationship as shown in I, the memo 'J' is
The information is stored sequentially at a fixed address in the MEM.

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 number of needle unit setting field 1s. The output is converted into a binary number by a code converter 76 and is input to a read address designation circuit RA, which will be described later.

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

That is, the four pulses are counted by the counter 78, and the decoder 79 reads "1" as shown in X and XIX according to the number of pulses.
~ Output is generated from the output system of “4” and the pulse discrimination circuit 77
The gates in the pulse discriminator circuit 77 are opened respectively, and the output systems "l" to "4" of the pulse discrimination circuit 77 are set to XX and XXI.
As shown in K, outputs are produced sequentially in accordance with the order of the pulses.

The four pulses separated by the pulse discrimination circuit 77 are input to a function storage circuit 80 composed of a D-type flip-flop, etc., where the sampling of the output (2) from the effective scanning data forming circuit C is This is performed for each entry grid row in the faction mark entry field 1f, and the sampled data is stored separately for each entry grid row as shown by X■.

Then, “1” to [
The outputs of "1" and "2" of the four output systems of j are input to the aforementioned card feeding and scanning control circuit SC, which will be explained in detail. The output of ``2'' controls the forward feed of ``1'', and the output of ``2'' controls reverse feed, and the outputs of ``3'' and ``4'' are input to the aforementioned function drive circuit FD. ,
Each of the required function operations other than card feeding is controlled.

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. 13 and 14.

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

First, operate the carriage in the usual way to perform the necessary knitting such as waste knitting, and then when the knitting is completed to the point where the pattern is to be added, the carriage Y is set on the left and right of the knitting needle group on the needle bed X at the needle selection receiving position. It is stopped outside one of the ends.

In this state, the card 1 is fed manually, that is, by manually rotating the wheel 14 fitted on the drive shaft 12, so that the upper and lower intermediate portions of the search mark 36 are moved to the scanning sensor C of the scanning member in the original position. Set it on the opposite side.

Afterwards, press the clear button CB above to clear card 1.
is transferred by one pitch in the forward or reverse direction (the direction in this case is not determined as will be explained later), and then the scanning member travels, for example, along the pi pi line shown in FIG. After the number of needle selection units is set as described above during the process, the forward movement 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 along the line P2 in FIG. When the robot travels back and forth and returns to the original position, the series of operations performed by operating the clear button CB ends.

After that, 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 31, 3r installed on the needle bed X. If the card 1 is moved back and forth about 18 times, the card 1 can be fed step by step and knit the knitting pattern exactly as drawn on it.

Now, when you operate the clear button CB, the corresponding signal (■ in Figure 14) will be reversed at knot 81 and OR 82.
After passing through the card, it is reversed again at knot 82' and is output as a card feeding and scanning instruction signal from the card feeding and scanning instruction circuit C8, and is passed through the card feeding and scanning instruction R-S flip-flop 83 in the control circuit SC and the scanning signal. An R-8 Noritsubu flop 84 for instructing forward movement of the member is set.

With the flip-flop 830 set, the Q output amount is:
The pulse from the timer 87 is passed through the AND gate 85 to open the AND gate 86 as shown by V, and the pulse from the timer 87 is passed through the opened AND gate 86 to the motor drive circuit CD.
The pulse motor a for card feeding is driven in the forward or reverse direction, so that the card 1 is transported in either the forward or reverse direction.

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 output pulse from the timer 87 that determines the feed amount for one pitch of the card 1 is sent to the D-type flip-flop 88.
is input to the T terminal of the flip-flop 83, and due to the fall of the Q output (■) of the flip-flop 88, the
is set to be reset.

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
Furthermore, the timer 87 includes an oscillator such as an unstable multivibrator and a binary counter that counts the oscillation signal, and the output of the counter is counted for a predetermined period of time. In addition, the counter is reset by increasing the rLl output of the flip-flop 83.

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

Therefore, when the timer 87 outputs just one pulse, it stops operating and the AND gate 86 closes.
Only one pitch of card 1 is sent.

By the way, when the clear button CB is operated, the R-S flip-flop 89 is set, and its output causes the feed direction reversal circuit 90 to be set for the set time, that is, until it is reset by the right limit switch 33r.
is controlled, the output operation of the motor drive circuit CD is switched, and the card 1 is transferred in the opposite direction, but if the clear button CB is operated in the above state. Sometimes card 1
Since it is not determined whether the R-S flip-flop 91, which indicates the feeding direction of the paper, is in the set state or the set state, it has not been determined in which direction the one-pitch transfer will be carried out.

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 step 83 with knot 93 is input manually, when the flip-flop 830 is being set, that is, when the card 1 is being transferred, the output of AND 92 is connected to the above-mentioned scanning member drive circuit SD. is not driven to move the scanning member forward, but only when the card 1 is at rest.

This forward movement is caused by the flip-flop 8 as shown in Figure 14 (■).
4 is terminated by being reset by the right limit switch 39r, and at the same time, the R-S control flop 94 for instructing the scanning member to move backward is set, so that the scanning member starts to move backward immediately.

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 original position return signal is delayed as shown in FIG.
This resets the scanning member so that it is given a force that causes it to move further to the left even after reaching the left stroke end, thereby preventing the above-mentioned risk. This is to prevent it.

As described above, by operating the rear button CB, the scanning member b is
When fJ'' moves back and forth once, during the forward stroke, the number of needle selection units programmed in the number of needle selection units selection column 1s is electrically set by the number of needle selection units setting circuit NS as described above. When this setting is made, R in the card feeding and scanning instruction circuit C8 is activated by one pulse (Fig. -S flip-flop 96 is set, and its Q output (■ in the figure) is passed through the OR 82 and knot 82' to the card feeding flip-flop 83.
and set the flip-flop 84 for forward movement of the scanning member again.

However, the AND gate 86 is designed to receive the signal from the left limit switch 331 via the knot 97, and opens only when the scanning member is in its original position. The card 1 will not be 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 is already set as described above, so the pulse of the timer 87 is input to the motor drive circuit CD through the AND gate 86 as shown by V, 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 previously been reset, has been reset by the right limit switch 33r, the Q
Since the output is directly applied to the motor drive circuit CD through the feed direction reversing circuit 90, 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 motor drive circuit CD, and conversely, the above output is input to the motor drive circuit CD. is rHJ
The above input is inverted when the flip-flop 91 is set, and its Q output becomes "H" to instruct forward feeding of the card 1, and when reset, its Q output becomes "H". The output is rHJ, which instructs reverse direction feeding.

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 feeding flip-flop is activated by the output () of the D-type flip-flop 88. 83 is about to be reset.

However, since this flip-flop 83 has priority over the set signal, the flip-flop 96 supplying the set signal also receives the AND 990 output X (the valid Since it is not reset by the output of the scanning data forming circuit C (reset by a falling edge), the set state is still maintained, and 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 card feeding flip-flop 83 disappears, but the flip-flop 83 is reset. The input to the D terminal of the D-type clip-flop 88 (the output of the effective scanning data forming circuit C) also corresponds to the no mark, so the output of the D-type flip-flop 88 resets the flip-flop 83 as shown in (■). However, since the flip-flop 83 still maintains the set state, the card 1
continues to be transported in the forward direction even in the unmarked section where the search mark 36 is removed.

When the lowermost one of the feed control marks 34 is detected by the scanning sensor C due to such continuous (forward direction transfer),
As the D-type flip-flop 88 resets the flip-flop 83, the transfer of the card 1 is stopped.

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 changed to
3 reset, the scanning member drive circuit SD is input via the AND 92, so that the scanning member reciprocates and the scanning sensor C moves the card 1 to the first position.
Figure 2 p2 The scanning member scans along line P2 and stops when it returns to its original position, thereby completing the above-described series of operations.

It should be noted that the digital electrical signal representing the knitting pattern obtained by the first one-stage scanning (Fig. 12 be.

The first scanning of the composition 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 is reversed, the carriage traveling direction detection switch part e in the carriage reversal switch mechanism E is activated.
The output of 1 (Fig. 15 ■) is inverted from rHJ to rLJ or vice versa, but this inversion is a knot, 2
The carriage reversal detection circuit 100, which includes two differentiating circuits and a NOR circuit, outputs the signal shown in FIG. Ru.

When the carriage Y enters the effective needle selection range defined by the left and right switch actuating pieces 31 > 3r by traveling after this reversal, the output of the effective needle selection range indication switch e3 changes to the 15th point as described above. As shown in Figure ■, rHJ is obtained, so this output and the Q output of the flip-flop 101 mentioned above ■
The input AND102 outputs a signal "H" as shown in V.
This signal passes through the or 82 and is output to the knot 82.
1 is inverted as shown in ■, and then output from the card feeding and scanning instruction circuit C8 as a card feeding and scanning instruction signal, and the flip-flops 83 and 84 in the control circuit SC are inverted as shown in ■ and xm. It is designed to be set.

By the way, since the output of the knot 82' is also used as a reset signal for the flip-flop 101, the flip-flop 101 is reset the moment the output of the knot 82' occurs, and as a result, the AND10
2. Note) The output of 82' becomes a trigger waveform as shown by V and VI.

By setting the flip-flop 83, the pulse ■ from the timer 87 is inputted to the motor drive circuit CD through the AND gate 86 as shown in ■, and the first pulse ■ Therefore, the feed control mark 34 is first sent in the forward direction by one pitch, but because the feed control mark 34 misses the scanning sensor C by this one pitch movement, the output ■ of the effective scanning data forming circuit C corresponds to a no mark. As a result, the above-mentioned flip-flop 88 does not reset the flip-flop 83, and the timer 87
The next pulse is output and the card 1 is further moved by l pitch.

When the card 1 is transferred in this manner and the next feed control mark 34 is detected by the scanning processor C, the flip-flop 83 is reset and the transfer of the card 1 is stopped, and instead of the card 1 that has already been set. The Q output X of the flip-flop 84 for instructing forward movement of the scanning member
is input to the scanning member drive circuit SD via the AND 92 as shown in XIV, so the scanning member moves forward immediately after the transfer of the card 1 is stopped, and the right limit switch 33r is turned on. By the way, the output
The flip-flop 84 is reset by V, and instead, the flip-flop 94 for instructing the scanning member to move backward is set, so that the scanning member moves backward and stops when it reaches the original position, completing the scanning of the first stage of cards. .

Thus, the carriage Y is moved between the left and right switch activation pieces 31.3.
Every time card 1 is moved leftward or rightward from outside the range of r to within the range, card 1 moves to the feed control mark 34...
. . . It is automatically transferred by the interval length of . . . and is scanned by the scanning sensor C for each stage.

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

Further, when the stop button SB is operated, the AND gate 86 is closed, so that even if 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 AND 102 generates the output shown in FIG. The same operation is performed even if the needle is entered from the direction of , but if button W is operated, the carriage Y will be reversed from the left row to the right row and the needle selection will be within the effective needle selection range from the right side. Only when entering
Another AND 103 generates an output, and card feeding and scanning are performed only at that time.

Furthermore, the clear button CB functions as a kind of start button when starting the scanning of card 1 as described above, but if it is operated during the scanning stage of the knitting pattern, each time the clear button CB is operated, card 1 is It is possible to transfer only one step in the opposite direction from the previous step,
This is clear from the above.

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 IJME as a compatible digital electrical signal
Next, by reading out the digital electrical signals stored in this memory MEM in accordance with the travel timing of the carriage Y while it is traveling within the effective needle selection range, The output function portion for causing the left and right knitting needle sorting mechanisms Fl and Fr to sort the knitting needles N will be explained with reference to FIGS. 16 and 17.

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

This read address designation circuit RA includes an up/down counter, and is configured to count the timing pulses manually input from the timing pulse generators H1 and Hr each time the carriage Y travels by one pitch of the knitting needles. However, the counted value is based on a parallel binary signal (more specifically, the 11th
By inputting the output of the code converter 75 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 column 1s of the card 10. At the same time, the switching of addition and subtraction is performed by a signal (2) representing the carriage running direction from the carriage running direction detection switch section e1, and the timing pulse is added or subtracted depending on the carriage running direction. It looks like this.

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 electrical signal) is repeatedly obtained as shown in (3).

In other words, it can be said that this circuit RA encodes the knitting needles N between the left and right switch activation pieces 31t3r and increments a repetition number in a constant direction.

Therefore, the output of this circuit RA is supplied to the aforementioned memory control circuit MC as a read address designation signal (read instruction signal) corresponding to the memory MEM, and also represents the aforementioned carriage running direction. The signal ■ is sent to the memory control circuit MC, and the memory IJM is sent to the memory control circuit MC.
The digital electrical signal stored in the memory MEM is input as a signal to determine which of the two storage sections of the EM is to be read. In this example, 12 bits from 0 to 11 are read out repeatedly, and as shown in It has become.

The waveform processing circuit WP is inputted with the signal (■) representing the effective needle selection range from the effective needle selection range indicating switch section e3, and only during rH1, the signal from the memory control circuit MC is treated as valid and the electromagnet is activated. Drive circuit M
D, and the output of this drive circuit MD is supplied to one of the knitting needle sorting mechanisms Fl, which is the one that performs effective sorting, by means of the electromagnetic changeover switch section e2.
Alternatively, it is input to the Fr electromagnet 46.

(Thus, the knitting needles N between the left and right switch actuating pieces 31t3r are arranged in groups of 12 as shown in
Sorting according to the form of the knitting pattern drawn between the grid on the right side of the piece (for example, in Fig. 17, the oval shown by the solid line is the forward bias, the filled-in oval is the backward bias,
The oval shown by the broken line is in the rest position where it is not subjected to needle selection action).

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 bits of the digital electric signal obtained by the one-stage scanning are stored in the memory MEM, and are read out from there. The number of bits is determined by the number of needle selection units programmed by marking the number of needle movement unit setting field 1s. For example, if it is set to "12", the number of bits is determined by the number of needle selection units programmed by marking the number of needle movement unit setting field 1s. Even if a knitting pattern is recorded further to the right of the 12th entry grid, the recorded portion on the right side is scanned and temporarily stored in the memo IJMEM, but it is read out as a signal for needle selection. It will never happen.

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.

By switching the manual operation section of the pattern left/right selection means RLt3, the output electric signal changes to rH as shown in FIG.
The signal is inverted from J to "L" or vice versa as shown by The addition/subtraction direction of the up/down counter of the read address designation circuit RA is designated by the comparison signal (2).

Therefore, the count value of the read address designation circuit RA is determined based on the operation of the pattern left/right selection means RL, depending on whether the carriage Y takes the above-mentioned food relation or the Xv relation when the carriage Y travels in a certain direction. Even if the knitting patterns on card 1 are the same, the knitted patterns in the cases of ■ and XV are as if the left and right sides were reversed.

Next, the pattern mode selection means MS outputs an electric signal that inverts from "circle" to "H" or vice versa as shown in (■) 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 MC as it is without inverting it, or to invert it as shown in (3). .

Therefore, by operating this means MS, it is possible to reverse the front and back sorting manner of the knitting needles N, thereby making it possible to reverse the ground pattern of the knitting manner without changing the knitting turn on the card 1. It is possible.

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 sprocket belt 81.degree. 8r was used as the support for supporting the card 1, but a drum or the like having sprockets formed on both sides of the circumferential surface may also be used.

Further, in the above embodiment, the scanning member 1 is scanned after the card 1 is transferred, but it is also possible to perform the card 1 transfer after the scanning member 10 is moved. It is.

Further, in the above, the left and right switch activation pieces 31.3r are arranged on the needle bed X as point setting means for dividing the effective needle selection range, and the switch activation pieces 31.3r are placed on the carriage Y as point detection means. Mechanical needle selection end detection switch mechanisms Gl and Gr are provided, which operate the switch by engaging with the point setting means.A member with an optical mark is placed on the needle bed It may be detected by a charging sensor as a point detection means provided on the carriage Y side, and a reed switch as a point setting means is mounted on a guide rod or the like installed horizontally on the X side of the knitting machine body so as to be able to slide left and right. However, even if the carriage Y is equipped with a permanent magnet and the reed switch is operated when the carriage Y approaches the reed switch, the left and right ends of the effective needle selection range can be electrically detected. It is.

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 driven.

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.

In addition, 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 knitting patterns, function marks, and needle selection unit number setting marks 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.

In summary, in the present invention, an information recording medium recording information such as a knitting pattern representing a pattern to be knitted is removably supported on a recording medium support, and can be transferred by rotating the recording medium support. In the information reading device for a knitting machine equipped with a transfer mechanism as described above, a pulse motor capable of forward and reverse rotation is connected to the recording medium support to rotate the recording medium support, and a predetermined information recording row of the above-mentioned news recording medium. Transfer direction determination that can determine the subsequent transfer direction of the information recording medium in relation to an electric signal related to reading information recorded on the media or manual operation of a manual operation member (clear button CB in the embodiment) means (flip-flops 89, 90° 910 coupling circuit in the embodiment) and the pulse motor drive circuit according to the transfer direction determined by the transfer direction determining means, and the information recording medium is provided with information to be recorded thereon or manually. The device is characterized in that it can be automatically and intermittently transferred in the forward or reverse direction based on manual operation of the operating member.

Therefore, according to the present invention, the information recording medium can be automatically transferred in either the forward or reverse direction using a pulse motor capable of forward and reverse circuits, which is much faster than the conventional method using an electromagnet and ratchet mechanism. It can be transported at a high speed, and in particular, a continuous feeding operation that automatically and continuously feeds an information recording medium over a long distance can be performed in an extremely short time.

In addition, since the pulse motor moves reliably in steps by itself, there is no need for a conventional Rickstop mechanism, and the transfer mechanism can be extremely simplified. This can be easily done by controlling the motor drive circuit that carries out the process, and if the pulse motor is de-energized, the recording medium support becomes completely free, so loading the information recording medium onto the recording medium support and It is very easy to remove it from there.

Furthermore, the forward and reverse rotational directions of the pulse motor can be controlled by electric signals related to reading of information recorded in a predetermined information recording string of the information recording medium or by manual operation of a manual operation member, and thus the subsequent rotation direction of the information recording medium. Since the transfer direction can be determined, the transfer direction can be programmed arbitrarily on the information recording medium, and the transfer direction determined by reading the information on the information recording medium can be arbitrarily programmed using a manual operation member. It can be changed in an interrupt manner.
