Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a knitting information reading method for reading knitting command information recorded (programmed) on a predetermined recording medium in order to perform desired knitting in a knitting machine.

Conventionally, as a method for reading this type of knitting information, a common method has been to record the pattern of the pattern to be knitted in a multi-stage perforation array on a card, and then mechanically detect the presence or absence of perforations in each row. It is being

However, in the case of this method, if you want to create the pattern of the pattern you want to knit, you have to drill holes in the card regularly, one at a time, at fixed coordinate positions. A pattern representing a so-called unit pattern to be created must be subdivided into typemes (minimum constituent units of a pattern, corresponding to the above-mentioned holes) in advance, and each of the typemes must be regularly arranged and recorded. A pattern representing a uniform knitting pattern must be digitally recorded in advance for each knitting needle, and this recording work is troublesome and requires special care.

Therefore, the present invention does not have to subdivide the pattern representing the knitting pattern into pattern elements and record them digitally, but even if it is simply recorded in a solid analog manner as if drawing a picture, When reading the pattern recorded in this way, it is possible to read it as a digital electrical signal corresponding to each knitting needle, which makes it easy to record the pattern that represents the pattern to be knitted, and the digital electrical signal By reading the signal, we can adopt a digital electrical control method that allows us to easily perform various operations that were previously impossible to perform, from the time the signal is read to the final needle selection. The sampling density of the above-mentioned mold performed when reading the above-mentioned digital electric signal can be changed according to the number of needle selection units, so that the size can be changed by changing the number of needle selection units for the same mold. This paper proposes a completely new knitting information reading method that allows knitting of similar patterns that change depending on the number of units.

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 a reading device A equipped with a scanning member (not shown in FIG. 1) that optically scans the information displayed and recorded thereon;
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
On the needle bed
1 + 3 r is mounted at an arbitrary position, and on the back side of the bed plate 4 of the carriage Y that runs on the needle bed X, there is a
Although not shown in FIG. 1, a row of knitting needles are moved to the needle bed X using electromagnetic force 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 depending on the direction of movement of the carriage Y, 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 recorded information horizontally in a straight line, a corresponding electrical signal is output, and the subsequent processing of the electrical signal is performed using an electronic configuration. Furthermore, power is supplied to the electrical components of the left and right pair of knitting needle sorting mechanisms by a cord 6 that is stretched around the tension member 5 that applies tension to the knitting yarn, and the carriage Y is connected to the switch activation piece 31.
By reciprocating the knitting needles beyond the left and right sides of the switch actuating pieces 3 1 , 3 r, only the needles within the distance range of the switch activation pieces 3 1 , 3 r are subjected to the effective sorting action (even those within this range are at a rest position where they are not subjected to any sorting action at all). (excluding those listed in ).

First, let's talk about the mechanical configuration of the reading device A.
This will be explained in detail with reference to Figures 6 to 6.

The entire reading device A is mounted on a frame 7 further behind the rising wall X1 at the rear end of the needle bed To explain the mechanism, endless sprocket belts 8l 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 8l and 8r have sprockets 8' projecting from their outer circumferential surfaces at a constant interval to fit into the left and right perforations 1l of the knitting program card 1, and these left and right sprocket belts 81t8
r and the cross section U placed below it across between them.
Insert the card 1 between the letter-shaped card guide plate 9,
By fitting the perforation 1' to the sprocket 8', the sprocket belts 81, 8
r can support force 1 in a state bent into a U-shape,
In this supported state, the card 1 can be transferred in the direction in which the perforations 1' are arranged by being circulated by a transfer drive mechanism a installed on the right side of the 71-nome 7.

That is, each sprocket belt 8l, 8r is shown in FIGS. 3 and 4 (parts of the belts 8l, 8r are cut away).
As shown in the lower dog pulley 1 0 1 + 1 O
r and the small pulleys 11l and 11r diagonally above it, and the left and right dog pulleys 101 and IQr are the drive shafts 12, and the left and right small pulleys 11l, 11r.
1 1 r are connected to each other by a rotation shaft 13, and the drive shaft 12 is also integrally connected to the ratchet wheel 14 of the transfer drive mechanism a, so that the ratchet wheel 14 rotates. Accordingly, the left and right sprocket bells 8 1 and 8 r rotate simultaneously.

As shown in FIGS. 2, 4 and 5, the transfer drive mechanism a has a forward transfer piece 15 on the front side of the ratchet wheel 14.
Further, a reverse feed piece 15l is arranged on the rear side, and both of these feed pieces i s and i s' are each connected to a pair of electromagnets 1 6
, 16' are connected to the plungers 17, 17' by pins 18, 18', and both electromagnets 16. 1
The forward or reverse direction of the ratchet wheel 14 is determined depending on which of the ratchet wheels 6' is driven.

That is, both the sending pieces 15, 15' are always held in their claws 21 by the springs 19, 19' acting on them individually and the spring 20 stretched between them.
, 21' are set at the upper limit retracted position where they do not engage with the ratchet wheel 14, but the corresponding electromagnets 1 6 . 1 6' is repeatedly energized and deenergized by inputting a pulse electric signal, and the plunger 17 or 1 7'
By moving up and down, each of the guide pieces 22, 23 or 22', 23' moves up and down along the guide pieces 22, 23 or 22', 23' while rotating slightly, thereby repeating engagement and disengagement with the ratchet wheel 14. .

Therefore, depending on which of the pair of electromagnets 16 and 16' is driven, the forward and reverse directions of the ratchet wheel 14 are determined, and thereby whether the card 1 is sent in the forward direction (as shown in the lower part of Fig. 2). ) This determines whether to send the data in the opposite direction.

As mentioned above, the card 1 optically scans horizontally 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 deteriorate. In order to prevent this, a card receiving plate 24 is stretched between the left and right sprocket belts 81 and 8r, and furthermore, on the left and right sides of the left and right belts 81 and 8r, the card receiving plate 24 is placed on the left and right sides of the card 1. Left and right card holding pieces that lightly press the edges 2 5
It is equipped with 1 and 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.
In addition, each card holding piece 251t25r has a fulcrum on the axis of the drive shaft 12, and rotates around the fulcrum, as shown in the side view of the right side in FIG. It can move, that is, open and close, but the spring 26
The power door 1 is biased toward the rear side, that is, in the closing direction, by the perforations 1 on its left and right sides
'Sprocket bell} 8 1 , 8 Fit into sprocket 8 of r and card holding piece 2 5 1 t 2 5
By pressing the card with r, 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 in a straight line in this flat sloped portion. A traveling drive mechanism for causing member b to travel will be explained.

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

That is, as shown in FIG. 3, the scanning member b has left and right through holes 291 provided in its main body, the traveling body 29, slidably fitted into the upper guide rod 27, and
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 However, the permanent magnet 32 crosses the magnetic field that is always created, and the magnetic force acting between them causes the traveling body 29, and thus the scanning member b, to move to the left along the guide rods 27 and 28 depending on the direction of the current flowing through the coil 31. Or it will automatically drive to the right.

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. 7 (cross section taken along line II-II in FIG. 2), left and right limit switches 3 act to switch the polarity of the current flowing through the coil 31. 3 1 + 3 3
r is placed.

The limit switch 331 on the left side is turned on when the scanning member b collides with the left row, and the limit switch 33r on the right side is turned on when the scanning member b collides with the right row. limit switch 3
It moves left and right between 3 1 t 3 3 r, and these left and right limit switches serve as the left and right stroke ends, and as will be described later, the scanning member b is always located at the left stroke end and does not move from there. position, and in conjunction with the reversal of carriage Y, it moves rightward from its original position at a considerable speed to the stroke end on the right side, and as soon as it reaches the stroke end on the right side, it immediately reverses (turns around). ) It is designed to automatically provide continuous feedback to the original position, and the left and right I
The J mitt switches 33l and 33r also function as a means for detecting whether the scanning member b is in the original position or not (* indicates whether it is in the reverse position (right stroke end) or not. .

As shown in FIG. 3, the upper extension part 29' of the traveling body 29 of the scanning member b extends diagonally upward on the rear side and then diagonally downwardly, 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 b 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 recorder field 1f, which is the function mark recorder field 1f, which is the part where function marks are recorded, is set to the right side of the organized function information recording section, that is, the section where function marks are recorded. It is created by displaying grid division lines (red when red light emitting diodes are used) in advance using an appropriate display method such as printing, and is scanned with L on the left side of the knitting pattern entry field 1p. The card 1 is read by sensor C.
The feed rate can be controlled in advance by displaying a large number of feed control marks 34, for example, slightly thick black horizontal lines at regular intervals in the direction in which the perforations 1' are arranged. It's recorded.

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 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 shown in the same color as the grid dividing lines.

More specifically, in the knitting pattern entry field 1p, one minimum section, that is, one entry grid corresponds to one stitch,
Its horizontal arrangement, or row, corresponds to one knitting needle, and its vertical arrangement, or row, corresponds to a knitting stage (wale), and it is a so-called unit in which n horizontal rows of stitches constitute one group. When knitting a pattern, consider the vertical line at the left edge and the vertical line n vertical lines to the right as the boundary line, and draw a picture (knitting pattern) corresponding to the unit pattern to be knitted between them. For example, as shown in the figure, the image is extracted in black using a suitable writing instrument such as a pencil.

For example, when knitting a unit pattern of 30 stitches in a horizontal row by selecting 30 knitting needles as a group, the stitches must be selected within the range between the leftmost vertical line and the 30th vertical line. It is meant to draw a picture.

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 completely without filling in the grids one by one.

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

In addition, the function mark entry field 1f has its horizontal line 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 The columns (vertical arrangement) of the entry grid in the reporter field 1f are arranged on the same line as the knitting pattern entry field 1p and have the same number, but the number of columns (horizontal arrangement) is, for example, 36 in the knitting pattern entry field 1p. 4 compared to 4.

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

Further, in this example, each of the feed control marks 34 displayed in advance on the left edge is positioned on an extension of the horizontal center line of each stage of the entry grid in the knitting pattern entry field 1p. As will be described later, the card 1 is automatically advanced step by step for each step of the entry 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.

In this setting field 1s, a required number of individually independent rectangular entry grids 35 are arranged at regular intervals in the horizontal direction.
It is displayed in columns, and each entry grid is unique for setting a certain fixed number of needle selection units, and the set number of units is different from each other, The set number of units increases in the base of , and a number representing the number of needle selection units is displayed in advance in the same color below each entry grid 35.

In this example, the number of entry grids 35 is 6 in total, and the one on the left is the needle selection unit number ``6'', and the following numbers are ``12, 18, 24, 30, and 36J'' in hexadecimal.

Therefore, this needle selection unit number setting field 1s is also scanned by the scanning sensor C of the scanning member b, and it depends on which of the marking grids 35 is to be marked. The number of needle selection units is determined.

For example, when knitting a unit pattern using 30 knitting needles, the entry grid 35 displaying "30" is filled in black.

Furthermore, a search mark 36 is preliminarily displayed on the card 1 so that only the setting field 1s can be effectively read in the electrical signal processing process after reading by the scanning sensor C, as will be 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 entry grid 35 in the setting field 1s, and its position on the card 1 is in the direction in which the entry grid 35 is arranged. On the extension line and the feed control mark 34...
..., but its width is longer to the right than that of the feed control mark 34... and is between the feed control mark 34... and the knitting pattern entry field 1p. The length includes the width of the blank space.

Then, when the card 1 is loaded into the left and right sprocket bells F 8 1 + 8 r as described above and the scanning member b is at the original position (left stroke end), the length of the feed control mark 34 is A predetermined position within the range is read by a scanning sensor C, and the card 1 is automatically transferred according to the feed control mark 34 only when the scanning member b is in the original position. When member b reaches the reversal position (right stroke end), the register grid row at the right end of the function mark register field 1f can be read, and the range between these reading positions is It is designed to be read while the scanning member b is running.

Therefore, the card 1 is created by scanning the needle selection unit number setting field 1s with the scanning sensor C of the scanning member b before starting the knitting operation, and then repeating automatic step-by-step feeding with the knitting operation. , the knitting pattern entry column 1p and the function mark recorder column 1f are scanned for each stage by the same scanning sensor C, and such scanning is performed by the forward and backward moving strokes of the scanning member b as described above. However, as will be described later, only the electrical signals associated with the forward (rightward) stroke of the scanning member b are effectively extracted from the electrical signals associated with the scanning of both the reciprocating 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 on the background, and the scanning sensor C of the scanning member b scans the knitting pattern horizontally in a straight line for each row of grids drawn. 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 line in the same figure), the knitting pattern in the first row of entry grids, that is, the horizontal scanning mode of the knitting pattern, The electric signal obtained by scanning is a square wave, and if it is only this, there is no one-to-one correspondence between the electrical signal and 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 as in that case, and the search mark 36 that is displayed in advance is also read in the same way. These three types of electrical signals are separated from each other, and the electrical signals related to knitting or pattern reading are transmitted to the knitting needles and the same electrical system.
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 entry grid row (vertical row) in the function mark recorder field 1f. The mechanical structure of the sampling mechanism that performs such an operation, that is, the sampling operation, will be explained with reference to FIGS. 2 and 3.

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

In order to sample only the search mark 36 on the card 1, the 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. ,
One search mark sampling slit}38s is bored, and on the right side, a predetermined number (120 in this example) of knitting patterns for sampling the knitting patterns drawn in the knitting pattern entry field 1p. Sampling slits}38p... are spaced at regular intervals in a straight line toward the right from the position corresponding to the leftmost reporter grid row in the knitting pattern entry field 1p.
A predetermined number (four in this example) of function mark sampling slits 38f are arranged in a row to a predetermined position exceeding the right edge of p. of,
They are drilled in one-to-one correspondence with each entry grid row in the function and one-click entry field 1f.

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

As the scanning member b travels, the sampling sensor d is scanned through the slits 38s, 38p..., 38f.
It outputs a pulse, that is, a sampling pulse according to..., and the sampling pulse is the same as the electric signal related to the scanning of the scanning sensor C mentioned above, and the sampling pulse is the same as the electrical signal related to the scanning of the scanning sensor C, as described later. Of both the reciprocating strokes, only those related to the forward stroke are taken out as valid ones as shown in FIG. One sampling pulse for sampling, 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 slits 38p for that purpose was 120 and 120 sampling pulses were obtained because the number of rows (horizontal arrangement) of the grid to be filled in the knitting pattern entry field 1p was set to "36". In addition to the above-mentioned card 1, as described later, a card with the number of rows of 120J (Fig. 20) is prepared, and in this example, sampling is performed using this card of 120 as a reference. This is because there is.

Therefore, for card 1 whose number of columns is "36",
Three slits 38p correspond to each entry grid in the knitting pattern entry field 1p, and the entry 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 36 rows, the above three sampling pulses are changed as shown in Figure 13 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 entry grid, and
As shown in FIG. The digital electrical signal will be explained later. The images are stored sequentially in a predetermined memory from left to right.

Then, the stored digital electric signal is transferred to the carriage Y.
The needles are read out sequentially and repeatedly 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 mechanism 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 and 8.
This will be explained with reference to FIG.

As mentioned above, in this manual knitting machine, the effective scanning of the knitting pattern by the scanning sensor C of the traveling member b is performed only in the forward movement process, and the digital electrical signals related to the scanning are sequentially stored in the memory from left to right. In contrast to keeping the day memorized,
The actual needle selection operation, which is performed by reading out the digital electric signal stored in the memory, is performed for both the reciprocating strokes of the carriage Y, with the left and right needle selection and selection mechanisms operating alternately depending on the traveling direction of the carriage Y. In order to knit a pattern according to the knitting pattern drawn on card 1, it is necessary to detect the running direction of carriage Y and control the storage and reading of digital electrical signals in the memory using the detected signal. Must be.

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 Fig. 9. 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 sheath 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 slidable back and forth within a predetermined length range on the left and right sides.

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 that slide on the upper surface of the sheath frame 39 between two front and rear magnetic plates 431 and 43. The lower ends of the two magnetic plates 431 and 430 have a horizontally elongated hole 4' formed in the base plate 4 and an elongated hole 44' formed in the slide pipe 44 fixed to the base plate 4. The lower end surfaces of the magnetic plates 431 and 432 are always attracted to a carriage guide par 45 made of a magnetic material and placed horizontally on the needle bed X.

On the other hand, a microswitch e having three switch parts e1 to e3 is fixedly installed on the rear side of the sheath frame 39, and a lever e' of the switch e is installed on the rear wall of the sheath frame 39. The hole 4 of the magnetic plate 432 on the rear side passes through the window hole 39'.
3' is engaged.

Therefore, the switch actuator 40 is fitted into the sheath frame 39 so as to be able to slide freely within a predetermined range on the left and right, and is adsorbed to the carriage guide par 45, thereby allowing the carriage Y to move freely. When the carriage Y is moved to the left, it is slid to the right sliding limit position with respect to the sheath frame 39 and then moved with it, and when the carriage Y is moved to the right, contrary to the above, it is slid 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. Switch part e for detecting running direction, from Fig. 16 ■ or Fig. 18
As shown in Figure ■, by reversing the running of carriage Y, rHJ is
This is a binary electrical signal that can be inverted from rLJ to rLJ or vice versa.

Next, the left and right knitting needle selection mechanisms Fl and Fr, which ultimately select the front and rear knitting needles N, will be explained with reference to Figures 3, 8, and 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 are each made of magnetic material and are made of one piece.
One end portions 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 left and right long bat passage 491 formed on its lower surface, and in the bat passage 49,
It is possible to receive the selected needle N through the side cam 50 through the cross of the selected needle N set at the selected needle receiving position.

The front and back width of this butt passage 491 is almost the same as that of x N, and its upper wall surface is located at the outer half of the outer side when viewed from the carriage Y, as shown in FIG. 492 is a tapered surface that descends inward, and the inner half 493 is a horizontal surface slightly lower than the normal height of the cross.

Therefore, in the process of passing through this bat passage 49, the bat N is pulled out from the middle of the outer half 49 by the leaf spring 51 (
3) and is gradually pushed down against the inner half 493.
It comes into pressure contact with the batt passage 49 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 491, and the lower surface of the horizontal part faces the inner end of the bat passage 491.
, is a continuous surface that is flush with the inner half 493 of the upper wall surface.

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 an outer vertical portion 482 located outside the notch 481 is provided with a notch 481 that is vertical to the bottom of the carriage base plate 4. Although the magnetism acts on the inner vertical portion 483, it hardly acts on the inner vertical portion 483.

The magnetic conductor 48 has its outer vertical portion 482 along the rear wall surface of the bat passage 491, and the bat passage 49,
The vertical front surface from the outer vertical part 482 to the inner vertical part 483 faces inward from the inner end (bat outlet) of the bat passage 491 as shown in FIG. The surface is inclined to .

The horizontal width of the outer vertical portion 482 of the magnetic conductor 48 is a width t that is slightly shorter than the row pitch of the knitting needles N, and the batt K passing through the batt passage 49 is within this width of the outer vertical portion 482. The rear surface is brought into pressure contact with the vertical front surface of the magnetic conductor 47, and the head end is brought into pressure contact with the horizontal lower surface of the other magnetic conductor 47, and the front surface of the inner vertical portion 483 of the magnetic conductor 4B and the horizontal portion of the magnetic conductor 47 are pressed against each other. A rearwardly inclined gap passage 51 (FIG. 8) is formed between the rear end edge and the batt N.

Therefore, the knitting needles N whose batts N are inserted into the batt passages 49 are selected in the following manner.

Is the cross that entered A road 49 a carry? As the Y travels, it is gradually pushed down with its back and forth movement restrained, and the head end is brought into pressure contact with the horizontal lower surface of one of the magnetic conductors 47, and the vertical of the other magnetic conductor 48 is pressed while passing the width T. Press the rear side against the front side.

If the electromagnet 46 is in an excited state during this width t, that is, while the carriage Y is traveling for one pitch of knitting needles, the magnetic conductor 47
By exciting different magnetic poles in the and the outer vertical portion 48 of the magnetic conductor 48, a kind of magnetic path is formed between them through the Basotho N, and the outer vertical portion 48 of the magnetic conductor 48 moves backward. Because of the inclination, the bag If is slightly attracted and biased rearward along its outer vertical portion 48 and enters the gap passage 51 out of the horizontal lower surface of the conductor 47 and behind the horizontal portion of the conductor 47. It will immediately rise to its normal height on the side.

The cross that has entered this gap passage 51 is formed by a rising portion of the magnetic conductor 47 on the carriage base plate 4 and a rising portion extending from the inner vertical portion 482 (portion not subjected to the magnetic action of the electromagnet 46) of the magnetic conductor 48. Since a magnet piece 52 is disposed 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 path 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 de-energized state, the butt N is
Since it is not attracted by the outer vertical part 482 of the magnetic conductor 48, it continues straight even after passing through the butt passage 491 while being pushed down by the horizontal part of the magnetic conductor 47, and rises to a steady height beyond the inner edge of the horizontal part. Afterwards, it passes through a forward guide path different from that in the case of excitation.

The left and right knitting needle sorting mechanisms Fl, Fr are set to the one that should be effectively operated by switching the electromagnetic changeover 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 structure, and the knitting needles N with the butts R fitted in the butt passages 49 are moved to the sorting mechanisms Fl or Fr on the front side in the direction of movement of the carriage Y. However, the above-mentioned? Even if the inserted knitting needle N is located outside the range of the left and right points I and the needle selection range setting switch activation pieces 3 1 and 3 r serving as the setting means, the electromagnet 46 does not receive any excitation command and remains in a non-excited state, so that it is not subjected to the above-mentioned sorting action by the electromagnet 46. Next, see FIGS. 8 and 9 for such a configuration. Explain.

The left and right switch activation pieces 31 and 3r both have a cam groove 3 running left and right on their upper surfaces, and a needle groove X.
A plurality of protrusions 3 that fit into the knitting needle 2 from the upper side are formed protrudingly on the front end of the lower surface, and a plurality of butt handle grooves 33 on the front side are formed on the front side to tightly receive the butts N of the knitting needles N,
Both can be placed at any position on the needle bed X without moving left or right by fitting the protrusion 32 into the rear end of the needle groove X2 and further engaging the butt N' in the butt holder groove 33. Although this is the same, the shapes of the cam grooves 31 are symmetrical to each other.

That is, the left switch activation piece 31 is connected to the cam groove 31.
The front and rear cam parts 34, 350 that form the front and rear side walls of 0 are arranged in a saw-tooth relationship with the front side on the right and the rear side on the left, 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 switch mechanism for detecting the needle selection end, which is a pair of left and right point detection means that operate the switch by engaging the switch activation pieces 3 1 and 3 r as the carriage Y runs. It is equipped with G l and G r.

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 It is connected to the lever of a microsinch 56 mounted on the base plate 4, and as the carriage Y moves, the protrusion 55 passes through the cam groove 31 of the left or right switch activation piece 31, 3r. , the crank 53 rotates to switch the microswitch 56.

That is, the micro switches 56, 56 of the left and right switch mechanisms Gl, Gr have their corresponding protrusions 5.
5 and 55 are both turned on when they are within the distance between the left and right switch activation pieces 31 and 3r, and turned off when they are outside this distance.

The left and right protrusions 55 and 55 are located at the selection points of the left and right knitting needle selection mechanisms Fl and Fr, respectively, that is, on the rear extension line of the T-width portion,
The left and right switch mechanisms GL and Gr operate when the sorting points of the left and right knitting needle sorting mechanisms Fl and Fr approach the installation positions of the switch activation pieces 3l and 3r on the needle bed X, respectively, as shown in FIG. 18 II. , IV, it outputs an electrical signal that is inverted from rHJ to rLJ or vice versa, and the electrical signals from both of these switch mechanisms Gl and Gr are transmitted to the microswitch e of the carriage reversing switch mechanism E. The effective needle selection range indicating switch part e3 in the middle allows only the part on the side where effective needle selection is to be performed to be taken out.

Therefore, as shown in FIG. 18V, the effective needle selection range indicating switch part 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 interval is outside the above interval range, and during the above-mentioned "H" output, the above-mentioned memory that stores the digital signal related to the knitting or pattern is read out, and only during that time, the effective needle selection is performed. The electromagnet 46 on the operating side is controlled to be energized or de-energized.

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 31, 3r, but the reading is performed with the traveling speed of the carriage Y being constant and subject to large fluctuations. Therefore, it must be done in synchronization with the travel timing of the carriage Y.

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, on the rising wall X1 at the rear end of the needle bed X, slots 1 and X3 are arranged in a one-to-one relationship with the needle grooves X2.
・By reading as a kind of linear encoder as the carriage Y travels, the photoelectric sensors Hl and H
As shown in FIG. 18I, a pulse, that is, a timing pulse, is output from r in accordance with the traveling timing of the carriage Y, and this timing pulse controls the reading of the memory mentioned above. In this case, the photoelectric sensors Hl and Hr will be referred to as timing pulse generators.

Note that, of the pulses from the left and right timing pulse generators Hl 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 reversing switch mechanism E. It has become.

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

First, the card 1 is scanned and fed,
The structure 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. 11.

The electric signal related to the card scanning of the scanning sensor C is transmitted to the scanning member b by the effective scanning data forming circuit C.
Only those related to the rightward stroke from the original position, which is the left stroke end, to the reverse position, which is the right stroke end, are taken out as valid, and include the card feeding and scanning instruction circuit CS, needle selection unit number setting circuit NS, and memory control circuit. It is designed to be input to MC and function discrimination circuit FS.

The card feeding and scanning instruction circuit CS is configured to receive an electric signal when the left IJ mitt switch 331, which is a scanning member original position detection means, is turned on, and the instruction circuit CS is configured so that the scanning member b is Only when it is in the original position, the electrical signal from the effective scanning data forming circuit C is “H”.
” 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 feeding drive circuit CD according to the mark and no mark, and the electromagnet 16 or 16' for card feeding is driven, thereby causing the card 1 to be fed.
is displayed on it, the search mark 36, the feed controller 1.
The roll marks 34... are automatically transferred by the interval.

Further, the instruction circuit CS 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 CS
When the pointer moves from outside the effective needle selection range defined by the left and right switch activation pieces 3 1 + 3 r into the range, an instruction signal for starting the movement of the scanning member b 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 the scanning member reversal position detecting means, is turned on, thereby causing the control circuit SC to detect the scanning member reversal position. The drive circuit SD is controlled so that the drive circuit SD also supplies sufficient current to the coil 31 of the scanning member b to enable the scanning member b to travel back and forth at once.

On the other hand, the sampling pulses related to the linear encoder reading of the sampling sensor d are taken out as valid ones by the effective sampling pulse forming circuit D, and are inputted to the pulse separation circuit PS. The pulse for sampling the search mark 36, 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 knitting pattern are per one grid when using card 1 in which the number of rows of grids in the knitting pattern entry column 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 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 NS determines whether or not to thin out the pulses for sampling the knitting pattern and how many pulses to thin out, according to the stored number of needle selection units. In other words, 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. This 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 CS and the card feeding and scanning control circuit SC.
After the scanning member b scans the needle selection unit number setting field 1s once and returns to the original position, the scanning member b scans the card 1 at the bottom of the feed control marks 34... It is designed to automatically move until the mark is read.

The write address designation circuit WA includes a pinary counter that counts the pulses inputted from the pulse separation circuit PS as described above, and writes a parallel binary electric 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 An electric signal corresponding to the carriage running direction from the running direction detection switch part 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 memories. It is designed to be stored separately in each section.

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 sent to the function mark column 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 CS, control circuit SC, and memory control circuit MC operate 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. , 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. I have made it possible.

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

Next, please refer to FIGS. 12 and 13 for the specific configurations of the effective scanning data type circuit C, the effective sampling pulse forming circuit D, the pulse separation circuit PS, the needle selection unit number setting circuit NS, and the function discrimination circuit FS. explain.

The R-S flip-flop 60 is set by the left limit switch 331, which is the scanning member original position detection means, and reset by the right-hand limit switch 33r, which is the scanning member reversal position detection means, so that the scanning member b The AND gates 61c and 61d are opened only during the forward movement in which the sensor travels from the original position to the reversed position, and only during this period the output signal of the scanning sensor C and the output signal of the sampling sensor d are respectively in the effective scanning range. AND gates 6 1 c and 6 1 d are used as output signals of data forming circuit C and effective sampling pulse forming circuit D.
(Figure 13 V, IX,
(see I).

The output of the above IJ switch 331 is shown in Figure 13■
As shown in FIG. 3, when the scanning member b is at the original position, it becomes rHl when it moves away from rLJ, and this output causes the R-S flip-flop to separate the sampling pulse of the search mark 36. 62 is set when the scanning member b leaves the original position, and is reset by the fall of the first pulse (pulse for sampling the search mark 36) from the effective sampling pulse forming circuit D. It is now possible to do so.

The Q output of the flip-flop 62 opens the AND gate 63 which receives the effective sampling pulse form or the pulse from the circuit D. Pulses other than pulses for sampling the functional marks 36, that is, pulses for sampling the edit or pattern and pulses for sampling the function marks, are output.

On the other hand, the Q output of flip-flop 62 is added to AND 64, which is in turn the Q output of 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 D 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 transversely scanning (scanning along line p+P+ in FIG. 13, V in the same figure is the output waveform of the effective scanning data forming circuit C at that time), the search mark sampling slit 38s of the sampling sensor d linear encoder 37
When 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 output of this AND 64 (actually, the output obtained by inverting it at knot 64') causes an R-S flip-flop 65 to memorize that the search mark 36 has been detected.
is now set.

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

The AND 66 receives the Q output of the flip-flop 65, the Q output of the flip-flop 62, the output of the effective scanning data type circuit C, and the output of the effective sampling pulse forming circuit D. As is clear from the comparison of III, IV, V, and ■ in FIG. When the mark placed on the flop is detected, one pulse is output as shown in (2), 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 (2), 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 CS and the same control circuit SC as described later.

On the other hand, as mentioned above, the pulse ■ from the ANDKATE 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 selected needle unit number setting field 1s is detected by the gate 1/net 68 which uses the gate operation signal as the gate operation signal, it is written in the memory 69 for storing the number of selected needle units, and then it is stored in the memory 69 successively. It has become.

This memory 69 is the flip-flop 65? It is reset at the time of the rise of the force (2), 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 of ``2'' to open the AND gate 71, and if the value is 1211 or more, an output is generated from the output terminal of ``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 ■. It will be output.

The 120 pulses from the AND gate 711 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 ' output system includes a ternary counter and an AND gate connected to this output side, and as shown in
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 for storing the number of needle selection units, which stores the number of needle selection units programmed in the number of needle selection units setting column 1s in the card 1 as described above, is output from the pulse selection circuit 72. It is input to the gate network γ3 for selecting which of the three types of pulses to be actually used as the sampling pulse, and the number of needle selection units is 6 to 3.
6, an output is generated from the output system "3" of the gate network 73, the AND gate 743 is opened, and the above three types of ? Of the pulses, the pulse of It is supposed to pass through or 75, and further 66
~1200, an output is generated from the output system of "1", and the AND game 1-741 is opened, and the pulse of ■ is OR 75.
It is supposed to pass through.

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 grid rows entered in the knitting or 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 and 36, as shown in Figure 19, there are cards with the number of grid rows filled in as 60 and the number of needle selection units as 42,
48, 54, and 60 cards, and as shown in Fig. 20, 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
A total of three cards that can be selected as 14 or 120 are used depending on the number of needle units selected, and similar patterns are knitted for the same knitting pattern between these three groups of needle unit numbers. This is the main point of the present invention, and the details thereof will be described later.

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. It is input to the memory control circuit MC and the write address designation circuit WA, and thereby the output of the effective scanning data type control circuit C (the scanning sensor C
(in Fig. 13, the output when card 1 is scanned along the p2-p2 line is shown in ■), and among these, the output related to the scanning of knitting pattern entry field 1p is XVI
After being converted into a digital electrical signal corresponding to the knitting needles in a one-to-one relationship as shown in FIG.
The information is stored sequentially at a certain fixed address of M.

Memo! Do you want to store digital electrical signals in JMEM as described above for everything from the left edge to the right edge of the 1-level entry grid in the knitting pattern entry field 1p? However, the readout is repeated only for the number of needle selection units set in the number of needle selection units setting field 1s.In order to do this, the number of needle selection units set above is The stored hexadecimal-binary output of the memory 69 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 (2) for function mark sampling output from the AND gate 71 are separated from each other by a pulse discrimination circuit γ7 composed of a gate group.

That is, the above-mentioned four pulses are counted by the counter 78, and the decoder 79 thereby reads "1" to "1" as shown at X and XIX, respectively, according to the number of the above-mentioned pulses.
An output is generated from the output system "4" and the gates in the pulse discrimination circuit 77 are opened, so that the output systems "1" to "4" of the pulse discrimination circuit 77 output the above-mentioned pulses as shown in xx and xxt. The output is generated sequentially according to the order of .

The four pulses separated by the pulse discriminator circuit 77 are input to a function memory circuit 80 composed of a D-type flip-flop or the like, 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 function mark recorder field 1f, and the sampled data is stored separately for each entry grid row as shown in (■).

Then, “1” to “
Outputs of “1” and “2” of the four output systems of “4” are as follows.
This is input to the aforementioned card feeding and scanning control circuit 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" controls the feeding of the card in the backward direction. Further, the outputs of "3" and "4" are inputted 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 CS and the same control circuit S
The specific configuration of C will be explained with reference to FIGS. 14 to 16.

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, operate the carriage in the usual manner to perform the necessary knitting such as waste knitting, and when you have knitted to the point where the pattern is to be added, move the carriage Y to the needle selection receiving position on the needle bed X. It is stopped outside either the left or right end.

In this state, the card 1 is moved manually, that is, by turning the ratchet wheel 14 by hand, until the upper and lower middle portions of the search mark 36 are opposed to the scanning sensor C of the scanning member b in the original position. Set 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 described later), and then the scanning member b runs along, for example, lines p and P1 shown in FIG. After the number of needle selection units is set as described above during the forward movement, 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, and upon that detection it is stopped and the scanning member b is immediately moved 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 this, work necessary for pattern knitting, such as inserting the desired color scheme into the yarn opening of the carriage Y, is performed, and then the carriage Y is moved to the left and right switch activation pieces 3 1 t 3 installed on the needle bed X. If the card 1 is repeatedly moved back and forth until it exceeds r, the card 1 can be fed one row at a time and knit the pattern exactly as drawn on it.

Now, when you operate the clear button CB, the corresponding signal (Fig. 15 1) is inverted at knot 81 and OR 82.
After passing through the gate, the signal is reversed again at knot 82' and outputted as a card feed and scan instruction signal from the card feed and scan instruction circuit CS, and is sent to the card feed instruction R-S flip-flop 83 and the scanning member in the control circuit SC. An R-S flip-flop 84 for forward movement instruction is set.

With 830 sets of flip-flops, the Q output is
It is applied to a card feed drive control circuit 86 consisting of a gate network through an AND 85, and either one of the output terminals ``1'' on the forward direction sending side or ``2'' on the reverse direction sending side of this control circuit 86 is applied. For example, one pulse shown in ■ is generated from the output terminal "2", and the aforementioned card feed drive circuit CD is driven, and one of the pair of electromagnets 16 and 16' for card feeding is generated. Either one is operated to transport the card 1 in either the forward direction or the 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 b are opposed to the scanning sensor C of the scanning member b, the scanning is performed by one predetermined pitch.

That is, the card feed drive control circuit 86 drives the card feed drive circuit CD by an output pulse from a timer 87 that determines the feed amount for one pitch of the card 1, and the output pulse is a D-type flip-flop 88. The flip-flop 83 is reset by the rise of the Q output (2) of the flip-flop 88.

The output of the effective scanning data type control circuit C is input to the D terminal of the D-type flip-flop 88, and the flip-flop is connected to the right limit switch 33r, which serves as scanning member reversal position detection means.
Further, the timer 87 includes an oscillator such as an unstable multivibrator and a pinary counter that counts the oscillation signal, and the output of the counter is set to a predetermined value. It is designed to be finally outputted as a pulse with a time width, and its counter is reset by the rLJ output (2) of the flip-flop 83.

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 when the clear button CB is operated as described above, the timer 87 is activated. When one pulse is output and the card 1 is sent by one pitch, the search mark 36 still does not exceed the scanning line of the scanning sensor C in either the upper or lower direction. An rHJ output indicating that a mark has been detected is input from the data type control 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 during the set time, that is, until it is reset by the right limit switch 33r, the feed direction reversing circuit 90 is controlled by the output of the RS flip-flop 89 to drive the card feed. The output operation of the control circuit 86 is switched so that the card 1 is transferred in the opposite direction, but when the clear button CB is operated in the above state, the card 1 is transferred in the opposite direction. R-S flip-flop 9 to indicate direction
Since it is not determined whether 1 is in the set state or in the set state, it has not been determined in which direction the above-mentioned one pitch should be transferred.

When the transfer of only one pitch is completed, the scanning member b
moves back and forth.

That is, when the clear button CB is operated, the flip-flop 84 for instructing the forward movement of the scanning member is set as described above, and its Q output is input to the AND 92. Since a signal obtained by inverting the Q output of AND 93 at knot 93 is input, when the flip-flop 83 is being set, that is, when card 1 is being transferred, the output of AND 92 drives the aforementioned scanning member drive circuit SD. Thus, the scanning member b is not moved forward, but is moved forward only when the card 1 is at rest.

This forward movement is caused by flip-flop 8 as shown in Figure 15 (■).
4 is terminated by being reset by the right limit switch 33r, and at the same time, the R-S flip-flop 94 for instructing the scanning member to move backward is set, so that the scanning member b immediately begins to move backward.

In this backward movement, the scanning member b is connected to the left limit switch 33.
However, since the scanning member b collides with the limit switch 331 at a considerable speed, the reaction force causes the limit switch 3 to be turned on.
31 may chattering as shown in FIG.
The home position return signal from 1 is delayed as shown in FIG. Even after reaching the end, it is possible to apply a force that causes it to move further to the left, thereby preventing the above-mentioned fear from occurring.

By operating the clear button CB as described above, the scanning member b
When the needle moves back and forth, the delay unit number setting field 1s is set by the needle selection unit number setting circuit NS during the forward movement as described above.
The number of needle selection units programmed in the unit is electrically set. When the setting is done, one pulse ( The R-S flip-flop 96 in the card feeding and scanning instruction circuit CS is set by (■) in FIG.
2', set the card feeding flip-flop 83 again.

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 b is in the original position. Therefore, the card 1 will not be transferred while the scanning member b is running after the number of needle selection units is set.

When the scanning member b 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 setting the flip-flop 91 which instructs the card feeding direction via the OR 98, and by operating the clear button CB. Since the flip-flop 89 is reset by the right limit switch 33r, the Q of the flip-flop 91 is
output? The pulse is directly applied to the card feed drive control circuit 86 through the feed direction reversing circuit 90, and a pulse is outputted from the "1" output terminal as shown, so it is in the forward direction.

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

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

However, because this flip-flop 83 has priority over the set signal, and because the flip-flop 96 supplying the set signal is activated by the subsequent detection of the search mark 36, the output X of the AND 99 (valid scan data passing through the AND) Since it is not reset (reset by a falling edge) by the output of the output circuit C, 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 moves away from the position facing the scanning sensor C due to such forward movement, at that moment 7
The flip-flop 96 is reset and the set signal to the card feeding flip-flop 83 disappears, but the input to the D terminal of the D-type flip-flop 88 that resets the flip-flop 83 (output of the effective scanning data forming circuit C) also corresponds to no mark. Therefore, as shown in (3), the output of the D-type flip-flop 88 does not reach the point where the flip-flop 83 is reset, and the flip-flop 83 still maintains the set state, so 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 the continuous forward movement, the D-type flip-flop 88 resets the flip-flop 83.
Transfer of card 1 is stopped.

At the same time, the Q output X■ of the flip-flop 84 for forward movement of the scanning member, which has been set by operating the clear button CB as described above, is transferred to the scanning member drive circuit SD via the AND 92 by resetting the flip-flop 83. In response to the input, the scanning member b moves back and forth, the scanning sensor C scans the card 1 along the line p2P2 in Figure 13, and when it returns to its original position, the scanning member b stops, thereby pressing the clear button again. The above-described series of operations performed by operating the CB is completed.

Note that the digital electrical signal (■ in Figure 13) representing the knitting pattern obtained by the first one-stage scanning is written only in the two memory sections of Memo'JMEM at the same time. be.

The first scanning of the knitting pattern entry field 1p and the function mark writer field 1f of card 1 is automatically performed by operating the clear button CS as described above, but the subsequent scanning 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. 16 I) is inverted from rHJ to rLJ or vice versa, but this inversion is not, 2
The carriage reversal detection circuit 100, which includes two differentiating circuits and a NOR circuit, outputs the signal shown in FIG. .

When the carriage Y enters the effective needle selection range divided by the left and right switch activation pieces 3 1 and 3 r by running after this reversal, the output of the effective needle selection range indication switch e3 is activated as described above. As shown in FIG.
J, and this signal passes through the OR 82 to knot 8.
After being inverted as shown in ■ at 2', the card feed and scanning instruction signal is output from the card feeding and scanning instruction circuit CS, 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.

Incidentally, since the output of 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 knot 82' occurs, and as a result, AND 102 and knot 82' The output becomes a trigger waveform as shown in ■ and ■.

By setting the flip-flop 83, as in the case of operating the clear button CB described above, the pulse ■ from the timer 87 is activated by the card feed drive control circuit 86 as shown in ■.
Card feed drive circuit C through output terminal "1" of
D, and is first sent in the forward direction by one pitch with the first pulse (2), but because this one pitch movement causes the feed control mark 34 to miss the scanning sensor C, the effective scanning data is not formed. The output of circuit C corresponds to the no mark,
The D-type flip-flop 88 is a flip-flop 83.
However, the next pulse is output from the timer 87 and the card 1 is further transferred by one pitch.

When the card 1 is transferred in this way and the next feed control mark 34 is detected by the scanning sensor C, the flip-flop 83 is reset and the transfer of the card 1 is stopped, and instead of the already set Q output of flip-flop 84 for instructing scanning member forward movement■
As shown in ■, is input to the scanning member drive circuit SD via the AND 92, so the scanning member b moves forward immediately after the transfer of the card 1 is stopped, and the right IJ mit switch 33r is turned on. By the way, the output XV
As a result, the flip-flop 84 is reset, and instead, the flip-flop 94 for instructing the backward movement of the scanning member is set, so that the scanning member b moves backward and stops when it reaches the original position, completing the scanning of the first stage of cards 10.

Thus, the carriage Y is connected to 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...
The scanning sensor C scans each stage automatically.

Note that the "1" output of the function storage circuit 80 in the function discrimination circuit FS (a mark was applied to the leftmost grid row of the four grid rows in the function mark entry column 1f) The output of "2" (when a mark is placed in the second entry grid column from the left edge) is configured to set the 7 flip-flop 91 for instructing the feeding 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 above-mentioned stop button SB is operated, the card feed drive control circuit 86 is reset.
Even if the carriage Y is moved back and forth as described above, the card 1 is not transferred, and only the scanning member b 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. This is done in the same way even when entering from the right direction, but when button W is operated, the carriage Y is reversed from the left row to the right row and moves into the effective needle selection range from the right side. Only as soon as you enter
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 at the stage of scanning the knitting pattern, each time the clear button CB is operated, card 1 will be cleared. It is possible to transfer only one step in the opposite direction,
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.
Memory MEM as a digital electrical signal corresponding to
Next, by reading out the digital electrical signals stored in this memory MEM in accordance with the traveling timing of the carriage Y while it is traveling within the effective needle selection range, the above-mentioned Left and right knitting needle selection mechanism F
The output function portion that causes L and Fr to select the knitting needles N will be explained with reference to FIGS. 17 and 18.

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 timing pulses I inputted from the timing pulse generators Hl and Hr each time the carriage Y travels by one pitch of knitting needles. However, the counted value is based on a parallel binary signal (more specifically, the 12th
By inputting the output of the code converter 76 (shown in the figure), the number of needle selection units is preset to the same number as the number of needle selection units programmed in the number of needle selection unit setting column 1s of the card 1, and the addition and subtraction can be switched. , the timing pulse is added or subtracted depending on the carriage running direction.

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 31.3r and assigns a repetition number to them in a certain direction.

Therefore, the output of this circuit RA is supplied to the memory control circuit MC as a read address designation signal (read instruction signal) for the memory MEM, and the signal V representing the carriage running direction is supplied to the memory control circuit MC. is a memory control circuit MC, a memory MEM
It is designed to be input as a signal to decide which of the two memory sections of memory M is to be read out.
The digital electrical signal stored in the EM is
Regarding the data in the storage section corresponding to the running direction, the data of 12 pits of 0 and 1L in FIG. 18 are repeatedly read out, and as shown in The signal is input to the processing circuit WP.

The waveform processing circuit WP receives the signal ■ from the effective needle selection range indicating switch section 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 selector switch e2 to the electromagnet 46 of the knitting needle sorting mechanism Fl or Fr, which is the one that performs the effective sorting operation.
It is now entered into

In this way, the knitting needles N between the left and right switch actuating pieces 31.3r are arranged in groups of 12 as shown in ■, and 12 knitting needles are connected to the knitting pattern lattice at the left end of the knitting pattern entry field 1p and 12 knitting needles N between the left and right switch activation pieces 31.3r.
Sorting according to the form of the knitting pattern drawn between the grid on the right side of the piece (for example, in Fig. 18, 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 editing pattern entry column 1p is scanned over the entire length of its left and right ends, and all bits of the digital electrical signal obtained by the one-stage scanning are stored in the memory MEM, but they are read out from there. The number of bits to be displayed is determined by the number of needle selection units programmed by marking the number of needle selection units setting field 1s. For example, if it is set to "12", even if it is Even if the knitting pattern is recorded further to the right of the 12th entry grid than the left edge, the recorded part on the right side will be scanned and temporarily stored in the memo 'JMEM, but it will not be possible to select the needle. It is not read out as a signal to perform the operation.

With the above configuration, it is possible to perform unit pattern knitting according to the knitting pattern on card 1, but the main hand knitting machine can also knit the pattern that will actually be knitted without changing the knitting pattern. The mode 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 its output electric signal to "H" as shown in FIG.
'' to "L" or vice versa as shown by The direction of addition and subtraction of the up-down counter of the read address designating circuit RA is designated by the comparison signal (2).

Therefore, the count value of the read address designating circuit RA determines whether the above-mentioned relationship (■) or X (X) is adopted for the movement of the carriage Y in a certain direction based on the operation of the pattern left/right selection means RL. Even if the knitting pattern on card 1 is the same, the knitted patterns in the case of ■ and XV are as if the left and right sides were reversed.

Next, the pattern mode selection means MS outputs an electric signal inverted from "L" to rHJ or vice versa as shown in (3) by switching the manual operation section, and supplies it to the waveform processing circuit WP. This means that MS
By this operation, 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, the front and rear sorting mode of the knitting needles N can be reversed, and thereby the card 1
It is possible to reverse the ground pattern of the knitted pattern without changing the upper knitting pattern.

Furthermore, when the clear button CB is operated, the memory control circuit MC clears the stored contents of the memory MEM.

Above, we have described the case where the number of lattice rows to be entered in the knitting pattern entry field 1p is 36 and the number of needle selection units can be set to 6, 12, 36, card 1 is used. The mutual relationship between the three types of cards, ie, the card shown in FIG. 19 and the card shown in FIG.

In this example, as mentioned earlier, a card with 120 grid rows shown in FIG. 20 is used as a reference, and scanning member b
12 from sampling sensor d for one forward run of
0 sampling pulses are taken out once, and when the number of needle selection units is 66 to 120, 120 sampling pulses are taken out as is, and the number of needle selection units is set by the selection unit number setting circuit NS shown in Fig. 12. When is 42 to 60, every other piece is thinned out by 1 and only 60 pieces in total are taken out as valid ones, and when it is 6 to 36, every 3 pieces is thinned out by 2 pieces to take out only 40 pieces in total. It is designed to be taken out as a valid item.

In the card shown in FIG. 19, the size of one entry grid in the knitting pattern entry field 1p is twice as large as that of the card shown in FIG. 20, and in the card shown in FIG. is three times as thick as the card shown in FIG.

Furthermore, in the card shown in FIG. 20, the feed control mark 34 is filled in continuously from the position corresponding to the bottom edge of the knitting pattern entry column 1p to the position corresponding to the top edge, thereby making this card When the scanning member b returns to its original position and the timer 87 shown in FIG. This causes the knitting pattern entry column 1p to be scanned step by step.

Further, in the card shown in FIG. 19, the interval between the feed control marks 34 is 2 times the interval between the rows of the entry grid in the knitting pattern entry field 1p of the card shown in FIG. 20.
It is doubled, so this card has a timer of 8.
The card 1 shown in FIG.
The interval between 4... is three times the interval between the rows of the entry grid of the card shown in Fig. 20, and this card is designed to be sent every three pulses from the timer 87. There is.

However, as is clear from the above, when the number of needle selection units is 42 to 60 using the card shown in Fig. 19,
The sampling density for reading the knitting pattern recorded on the card is 1/2 of that when the card shown in Figure 20 is used and the number of needle selection units is 66 to 120. Use card 1 to select the number of needle selection units from 6 to
36, the sampling density is one-third that of the case where the card shown in FIG. 20 is used.

Therefore, if knitting patterns in the same manner and size are recorded for the three types of cards shown in Figures 2, 19, and 20, the pattern of the actual knitted fabric will depend on the number of needle selection units. When the number of needle selection units is set to 42 to 60 (using the card shown in Figure 19), the pattern is similar compared to when the number of needle selection units is set to 66 to 120 (using the card shown in Figure 20). However, the size is almost half, and when the number of needle selection units is set from 6 to 36 (using the card shown in Figure 2), compared to when it is set from 66 to 120. They are also similar, but the size is approximately one third.

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 such a machine.

That is, in the above example, three types of cards are prepared, one with 120 grid rows, one with 60 grid rows, and 36 cards with the number of grid rows entered in the knitting pattern entry field 1p, and these are arranged according to the number of needle selection units. In addition, the feed amount of these cards was determined by marking the feed control marks 34 on the cards themselves.
Using only 20 cards, on this card 6~
In addition to being able to set the number of needle selection units of 120,
Even if the feed amount is determined by automatically changing the number of pulses supplied to the card feed drive circuit CD in FIG. 14 according to the set number of needle selection units, the result is substantially the same as above. It is possible to read such knitting patterns and select needles based on that.

Further, in the above embodiment, the coil 3 of the scanning member b
1 is fitted into the guide rod 28, and by passing currents of opposite polarities through it, magnetic forces in opposite directions to the left and right are applied to the coil 31 using the permanent magnet 32 as a stator, thereby causing the scanning member b to reciprocate. However, two coils were used with the winding directions opposite to each other, and the guide rod 28 was made of a magnetic material.
The scanning member b can also be caused to reciprocate by passing current through the coils alternately so that a magnetic force is generated between the coils and the guide rod 28.

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

Further, in the above description, the card 1 is driven by the electromagnets 16, 16', but a pulse motor may also be used.

Furthermore, in the above, a card in which the two entry grids correspond to one stitch is used as the knitting or program card 1, but a card in which one entry grid corresponds to a predetermined plurality of stitches may also be used. , or 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.

Furthermore, in the above, the number of needle selection units is preset by providing a field 1s for setting the number of needle selection units on the card 1, marking it there, detecting it with the scanning member b, and using the number of needle selection unit setting circuit NS. This was done by electrically presetting,
It is also possible to manually preset using digitals, inches, etc. that can be manually set.

Furthermore, in the above (・, 1 of scanning sensor C)
All bits of digital electrical signals related to stroke scanning are temporarily stored in memory M. When storing data in the memory MEM and reading it, a mark is placed on the card 1 so that the data with a determined number of bits can be effectively read. At the stage before the card 1 is selected, the digital electrical signals are selected.
Even if the number of bits determined above are stored in the memory and all of them are read out when read out, unit pattern knitting can be performed in substantially the same way as described above.

As is clear from the above, the knitting information reading method of the present invention records knitting or pattern information representing the pattern to be knitted on a recording medium,
The knitting pattern information is detected as an electrical signal by scanning with a scanning member running on a predetermined trajectory, and the number of sampling pulses corresponding to the number of needle selection units set in advance for one stroke scanning of the scanning member is detected. By sampling the electric signal with the sampling pulse, the knitting pattern information is read as a digital electric signal with a bit number corresponding to the number of needle selection units, and the recording medium is read out with each scanning stroke of the scanning member. The knitting pattern information is automatically transported by a distance corresponding to the number of needle selection units in a direction perpendicular to the trajectory of the scanning member, and does not require special care in recording the knitting pattern information, and is read as a digital electrical signal. Therefore, as seen in the embodiments, various operations that could not be performed in the past can be realized very easily.

In addition, since the number of sampling pulses and the feeding amount of the recording medium are automatically changed according to the number of needle selection units set in advance, the sampling of knitting pattern information performed when reading the above-mentioned digital electrical signals Density can be changed according to the number of needle selection units, so for the same knitting or pattern information, by changing the number of needle selection units, the size will change depending on the number of needle selection units, but it will be possible to create similar patterns. can be organized.
