Description

[Detailed description of the invention] By scanning a recording medium such as a card on which a knitting pattern representing a pattern to be knitted is recorded and displayed with a scanning member, the knitting pattern is read as a binary electric signal and stored in a memory. A so-called hand-striped machine with an electronic configuration, in which the stored binary force signal is read out in relation to the movement of the carriage and the needle is selected according to the content, is known, for example, in Tokukan Sho 50-190764 and No. 50 This method is known from, for example, Japanese Patent No. -95556.

The present invention enables a hand knitting machine having such an electronic configuration to preprogram any green yarn to be knitted in the knitting stage by selectively applying marks at predetermined recording positions on the recording medium such as the card. By scanning the mark with the scanning member along with the knitting pattern, the program can designate the pattern from among a plurality of hem threads of different colors prepared in advance. Any color of knitting yarn can be automatically selected each time the above knitting pattern is scanned. Therefore, even with any color of knitting yarn specified by the above program, the pattern can be automatically knitted based on the above knitting pattern. The present invention proposes a new yarn selection method that can be carried out accurately and can accurately perform yarn exchange operations with respect to the yarn feeder of the carriage even with a small electromagnet.

In the following, the present invention will be explained in detail with reference to an illustrated embodiment in which the present invention is applied to a hand knitting machine equipped with a ribbing machine, a so-called double-plate hand knitting machine.

First, the overall outline of the hand knitting machine used to carry out the method of the present invention will be explained with reference to FIG. At the same time, a thread selector Z is installed at, for example, the left end of the needle bed X of the knitting machine body X of this machine, and the carriage Y on the machine side and the carriage Y2 on the rib machine side are They are connected to each other so that they can run together by a known arm Y' provided with a yarn feeder.

Then, in the rope machine main body X of this machine, a part of it is exposed on the upper cover X2 at the rear side of the needle bed X, and a knitting program card, which is a recording medium, is inserted into the part that is exposed. A scanning device S equipped with a scanning section (not shown in Fig. 1) for optically scanning the information displayed and recorded thereon is installed so that it can be automatically transported by the needle bed. X, on the top are left and right needle end setting members 31, 3 that can arbitrarily divide the needle selection range.
The knitting pattern on the knitting program card is scanned on the back side of the plywood of the needle bed The needle bed X,
A pair of needle selection devices, one of which effectively selects rows of knitting needles back and forth according to the direction of movement of the carriage Y, using electromagnetic force, are arranged at a predetermined length apart on the left and right sides.

The scanning device S is configured such that its scanning member automatically scans the information recorded on the card in a horizontal straight line in relation to the travel of the carriage Y, and outputs an electric signal corresponding to the information. Further, the subsequent processing of the electrical signal is performed by an electronic configuration, and power is supplied to the electrical components of the pair of left and right needle selection devices, for example, by a tension member T that applies tension to the rope yarn. By reciprocating the carriage Y to the left and right, the green needles arranged in rows on the needle bed X are set only within the range of the left and right needle selection end setting members 31 and 3r. Needles can be selected according to the above-mentioned knitting pattern. First, let's talk about the above-mentioned scanning device S.
This will be explained in detail with reference to FIG.

The entire scanning device S is mounted on a frame 5 below the upper cover X2. First, the recording medium transport mechanism therein, that is, the mechanism for loading and transporting the organization program card 1, will be explained. A card feeding roller 6 as a feeding material having sprocket wheels 61 and 6r on the left and right sides is rotatably constructed.

The sprocket wheels 61, 6r have sprockets 6' protruding from the outer circumferential surface at regular intervals, which extend into the left and right bar forations 1', 1'' of the formation program card 1. Wheel 61,6
r and the cross section U placed below it across between them.
Insert the card from the pattern card slot 9 facing on the upper cover
By aligning the sprocket wheel 6 with
1 and 6r can support the card in a U-shaped bent state, and in this supported state, it is rotated by a pulse motor a that drives the moving mechanism arranged on the right side of the frame 5, so that a force - Perforation 1′,
In other words, the card feeding roller 6 has a gear 10 iron-bonded to its shaft 7, which is meshed with a gear 11 mounted to the shaft of a pulse motor a. Therefore, it is linked to the pulse motor a.

Therefore, the pulse motor a is capable of forward and reverse rotation, and the forward and reverse direction of the card feed roller 6 is determined depending on whether it is driven forward or backward, and thereby whether the card 1 is sent in the forward direction or not. (Bottom side of Figure 2) This determines whether to send in the opposite direction.

Further, a finger wheel 13, a part of which projects upward through the window hole of the upper cover X2, is iron-mounted on the shaft 7, and the finger wheel 13 can be turned by hooking a finger on the cover X2. This makes it possible to transport cards manually. As mentioned before, the card 1 is inserted through the pattern card slot 9 on the cover X2.The slot 9 has a transparent plate 15 on the front side of the hanging part 14 of the cover Standing part 15' and hanging part 1 of
The cover X2 is arranged so that there is an appropriate gap between the cover X2 and the front surface of the cover X2 to allow the card to pass through. The card 1 that has entered the lower part of the cover X2 is led out through an exit 16 (FIG. 4) formed at the rear end of the cover X2.Next, the card 1 is scanned in a straight line so that the card The traveling drive mechanism for automatically traveling the village c will be explained.

Two upper and lower guide villages 17 and 18 are horizontally constructed in parallel to each other on the frame 5, and a scanning member c is mounted on these so as to be able to slide left and right.

That is, the scanning member c has left and right through holes provided in the main body of the traveling body 19 slidably fitted to the upper guide punch 17, and a bobbin integrally provided on the lower side of the traveling body 19. 20 is slidably joined to the lower guide village 18.

A coil 21 is wound around the two bobbins, and a permanent magnet 22 of the captain is placed slightly below the lower guide punch 18 in parallel thereto.

The entire length of the upper side of the permanent magnet 22 is, for example, an N pole, and the entire length of the lower side is an S pole.The lower guide village 18 is made of a magnetic material, and when a current is passed through the coil 21, the current is , the traveling body 19 crosses the magnetic field constantly created by the permanent magnet 22, and the magnetic force acting between them causes the traveling body 19 to
Therefore, depending on the direction of the current flowing through the coil 21, the scanning member c automatically moves to the left or right along the guide villages 17 and 18 as a guide means.

That is, the coil 21 and the permanent magnet 22 are
This constitutes a kind of linear motor with 2 as a stator.

Although the scanning member c is normally located at the left stroke end (the position shown in FIG. (when approaching the stroke end), run from the left stroke end to the right stroke end, then from the right stroke end to the left stroke end.
Coil 2 receives enough current for immediate feedback running.
1, so that one round trip from left to right can be performed at once without interruption.

At the beginning of the frame 5, a reversal position stopper 23 is provided at the right stroke end with respect to the scanning member c, while on the upper guide punch 17, the scanning member c
The original position stopper 24 is fixed at the position corresponding to the stroke end on the left side of the guide.
7 is mounted on the frame 5 so as to be able to slide left and right, and is urged rightward by a spring 26 at its left end, so that the scanning member c collides with the stopper 24 during backward movement (leftward movement). However, by buffering this impact with the spring 26, it is possible to prevent the reaction (rightward movement) when the left stroke end is reached. As shown in FIG. 4, on the rear side of the scanning unit village c, there is a height at which the card 1 inserted from the pattern card insertion slot 9 as described above is vertically positioned in front of the hanging portion 14 of the cover X2. Now, in order to scan the surface of the card, a so-called photoelectric sensor d is made up of a reading element, that is, a light-emitting element, and a light-receiving element that receives reflected light reflected from the card surface and converts it into an electrical signal. is installed.

As the scanning member c moves, its photoelectric sensor d optically scans the surface of the card horizontally in a straight line, and hereinafter the photoelectric sensor d will be referred to as a scanning sensor.

In addition, the cardo allows the forward movement (rightward movement) and backward movement (rightward movement) of the scanning member c.
The scanning sensor d scans in both strokes (left row), but the electrical signals associated with the scanning in both the reciprocating strokes are taken out as valid only those caused by the reciprocating strokes of the scanning member c. ing. next,
Card 1 will be explained with reference to FIG. 2. On the white surface between the left and right burrows 1' and 1'', there is a knitting pattern recording area lp, which is a part for recording knitting patterns, and a knitting pattern entry column lp on the right side. The organization function information recording part, that is, the function mark entry field lf, which is the part for recording function marks,
Using an appropriate display method such as printing, grid dividing lines in a color that is the same as the light emitting color of the light emitting element of the scanning sensor d and which the light receiving element does not discriminate (for example, red when a red light emitting diode is used as the light emitting element) are printed. It is created by displaying it in advance.

In the above-mentioned knitting pattern entry column lp, among the grid dividing lines composing it, the vertical lines are the dividing lines between stitches, and the horizontal lines are the dividing lines between knitting rows. More specifically, in the knitting pattern entry column lp, one minimum section, or entry grid, corresponds to one stitch, its horizontal arrangement, or row, corresponds to one knitting needle, and its vertical arrangement, or row, corresponds to one stitch. This corresponds to a knitting row (wale), and when knitting a so-called unit pattern in which one group consists of n horizontal rows of stitches, there are vertical lines at the left edge and only n stitches to the right. Regard the separated vertical lines as boundary lines, and draw a picture (knitting pattern) corresponding to the unit pattern to be knitted between them in black, for example, using a suitable writing shell such as a pencil. It is something.

・For example, when knitting a unit pattern of 48 horizontal stitches by selecting 48 knitting needles as a group, the vertical line on the left side and the 4th vertical line from that The purpose is to draw a picture within the range of .

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

This is because the reading is performed by sampling each filled grid, and this will be explained in detail later. Further, the horizontal line of the function mark entry field lf is on the same line as the horizontal line of the knitting pattern entry field lp, and the vertical line thereof is parallel to the vertical line of the knitting pattern entry field lp.

The function mark entry field lf indicates the required function operation, such as activating the notification means to notify thread exchange, deciding the feeding direction of the card itself, deciding which color thread to knit, etc. In this example, there are eight examples of input grids (in a vertical arrangement), of which four input grid rows IA, IB
, IC, and ID correspond to four knitting yarns, and depending on which grid row to mark, the 4
It is possible to specify the knitting yarn to be used in knitting the relevant knitting row from among the knitting yarns in the book.

As mentioned above, in the knitting pattern entry column lp of the card 1, a knitting pattern representing the unit pattern to be knitted is drawn on the background, and the scanning sensor d of the scanning member c normally draws this knitting pattern. The grid is scanned horizontally in a straight line for each stage of the grid, and the electric signal for each stage of scanning is a square wave corresponding to the form of the knitting pattern in the first stage of the grid, that is, the form of one horizontal scan of the knitting pattern. If this is the only electrical signal obtained by scanning, there is no one-to-one correspondence with the knitting needle to be used as a key needle, and the function mark entered in the function mark entry field lf is also Like the above knitting pattern, it is read by the scanning sensor d and becomes an electrical signal in the same electrical system, but these two types of electrical signals are separated from each other, and the electrical signal related to reading the knitting pattern is connected to the knitting needles. It is converted into a binary electric signal that corresponds 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 entry field lf. Next, a description will be given of a sampling mechanism that performs such an operation, that is, a sampling operation.

The frame 5 is located behind the traveling body 19 of the scanning member c.
, the horizontally long plate-shaped linear encoder 28 is connected to the guide village 17.
, 18. Linear encoder 2
8 is a predetermined plurality of knitting pattern sampling slits 28p for sampling the knitting pattern drawn in the knitting pattern entry field lp on the card, one to one for each written grid row in the knitting pattern entry field lp. The function mark sampling slit 28f. . . are provided in one-to-one correspondence with each entry grid row in the function mark entry field lf.

On the other hand, on the rear side of the traveling body 19 of the scanning member c, there is a photoelectric sensor for optically reading both of the two types of slits 28p and 28f, that is, a light emitting element that illuminates the front surface of the linear encoder 28 and its reflected light. A sampling sensor e consisting of a light receiving element that receives light and converts it into an electrical signal is attached. Therefore, as the scanning member c travels, the sampling sensor e outputs a pulse corresponding to the slits 28p and 28f, that is, a sampling pulse, and the sampling pulse is the same as the electrical signal related to the scanning of the scanning sensor d described above. As shown in FIG. The sampling pulse and the sampling pulse for sampling the function mark are separated from each other. Thus, although the electrical signals associated with one-stage scanning of the knitting pattern entry field lp and the function mark entry field lf are sampled for each entry grid, it is possible to ensure that such sampling is accurate for each entry grid in relation to the card 1. , the card guide plate 8 has slits 8P and function mark entry fields corresponding one-to-one to each entry grid row of the knitting pattern entry field lp along the scanning line of the scanning sensor d. A slit 8f corresponding to each entry grid row of lf is provided in a one-to-one relationship, and the scanning sensor d picks up marks on the card for each slit through these slits. It's summery.

Therefore, the electrical signals related to reading the knitting pattern are
Each bit corresponds to an entry grid, and therefore one knitting needle, and depending on whether each entry grid is marked or not, the binary number “1”
" or "0" is converted into a binary electric signal with a predetermined number of bits, and all bits related to one stage scanning of the scanning member c are sequentially stored in a predetermined knitting pattern storage memory from left to right. However, the number of bits read from this can be determined by rotating the needle selection unit number setting finger wheel 29, which partially faces the cover X2, to move the pointer 31 of the moving body 30 below the transparent plate 15. It is determined by the number indicated by the pointer 31 by matching the scale on the scale plate 32 provided in the
This also determines the number of needle selection units.Next, a mechanism for setting the number of needle selection units for setting the number of needle selection units will be described.

The moving body 3 is mounted on the frame 5 so as to be able to slide left and right along the rail plate 33 constructed horizontally, and a right pulley 34r integral with the finger wheel 29. It is connected to a finger wheel 29 by a string 35 that is passed around a pulley 341 on the left side, and by turning this finger wheel 29, it is slid from side to side.

A reflecting plate 36 is vertically mounted on the movable body 30 and is pressed against the front surface of the card guide plate 8.

The front surface of this reflector plate 3.6 is mirror-finished and has a much better light reflectance than the front surface of the guide plate 8 and the card 1 surface.

Therefore, the scanning sensor d is connected to this reflector 36.
, the output voltage of the scanning sensor d (specifically, the output voltage of the light receiving element) suddenly increases.

Therefore, if the voltage at this time is determined experimentally in advance and a voltage slightly lower than that is used as a reference voltage to detect when this voltage is exceeded, the scanning sensor d will eventually face the reflector plate 36. This means that it can be detected. The sampling pulses from the sampling sensor e are counted by a counter until the scanning sensor d detects the reflection plate 36, and the counted value is stored in a predetermined memory. The binary military signal stored in the knitting pattern storage memory has a number of bits corresponding to the stored count value, and is read out sequentially. The number is determined, and based on this, so-called unit pattern knitting is performed. ，
Next, the aforementioned thread selector Z will be specifically explained with reference to FIGS. 5 to 11.

The yarn selector Z is removably installed on the left side of the knitting machine body X by means of an attachment arm Z.

A frame Z is installed on the mounting arm Z, and all the components of the thread selector Z are mounted on this frame Z. Four yarn feeders 5 are placed on the rectangular slope at the tip of the frame Z.
0^, 508, and 50o are arranged on the left and right so that they can be moved back and forth individually.

That is, the yarn supplying bodies 50^ to 50o have the same configuration (hereinafter, they will be collectively referred to as yarn supplying bodies 50), and are respectively placed in grooves 51 provided in the frame Z so as to be slidable back and forth. .

The thread body 50 includes a base plate 52 made of synthetic resin and a hook 53 at the rear end (upper side in FIG. 5).

The base punch 52 has a hollow part 52' as shown in FIG. 7, and is pushed forward (
(left side in FIG. 7), and is always held at a predetermined position in front.

That is, the protrusion 51' standing up on the bottom surface of the groove 51
has protruded into the hollow part 52', and the spring 54 is applied between the protrusion 51' and the front inner end of the hollow part 52'. It is urged forward to the point where the rear inner end engages with the protrusion 51'.

In this way, the yarn supplying bodies 5 and 5 are normally located at predetermined original positions po (in FIG. 5, the yarn supplying bodies 50^, 50
B is in this position).
Each yarn supply body 50A to 50.

, the electromagnets 55A to 55A are connected to each other at the front end thereof.
55. are installed correspondingly, and electromagnets 55A to 55 are installed. The yarn feeders 50^ to 50D (hereinafter collectively referred to as electromagnets 55) are energized by yarn feeders 50^ to 50D, as shown in FIG. It retreats to the standby position p, and is kept at this position p (the yarn supplying body 50e is in this position in FIG. 5). That is, a coil 57 is wound around a bobbin 56 that slidably receives the front end of the base punch 52 of the yarn supplying body 50, while a U-shaped cross section made of ferromagnetic material is attached to the front end of the base punch 52. A plunger 58 is attached, and when current flows through the coil 57, that is, when the electromagnet 55 is energized,
The yarn supply body 50 is moved back from the original position po against the spring 54 to a yarn supply exchange standby position p, and is kept at this position p while the electromagnet 55 is energized.

When the yarn feeder 50 is held in the yarn feeding exchange standby position p in this manner, the carriage Y moves to the left and the actuating piece 59 attached to the arm Y attached thereto is pivoted to the frame Z. When the passive piece 601 of the rack collides and rotates, it is moved back by mechanical force from the yarn feeding exchange standby position p, as shown in FIG. 7, and is displaced to the yarn feeding exchange position p2. is mechanically held at this position p2.

That is, when the activation piece 59 moves to the left as shown in FIG. 8 and the driven piece 60 is rotated counterclockwise as shown in FIG. A cam 62 integrally equipped with a meshing gear 61 (FIG. 5) rotates clockwise in the figure, and as a result of this rotation, a slider 63 having an approximately L-shape in plan, which is linked to the cam 62 by a slider crank mechanism, rotates. It is designed to recede horizontally above the yarn supplying body 50.

The slider 63 is the yarn supplying bodies 50A to 50.

The preset bar ~ 6 is installed so that it can be slid left and right along the portion 63' that crosses them above.
It consists of 4. The preset bar 64 is biased to the left by a tension spring 65 (FIG. 6) stretched between it and the slider 63, and is normally kept at a limit position on the left side with respect to the slider 63.

The preset bar 64 is set to the base 5 of the yarn supply bodies 50^ to 50o
A total of four engaging pieces 64' facing the planar triangular protrusions 52'' provided on the upper surface of the yarn supplying body are vertically connected to each other, so that the engaging pieces 64' are vertically connected to each other. When retreating from the original position po to the yarn feeding exchange standby position p,
The engagement piece 64' is pushed to the right by the oblique side of the protrusion 62'' and is displaced to the right against the force of the spring 65, thereby allowing the yarn supplying body to retreat.

Therefore, the yarn supplying body 50, which is allowed to retreat as described above and is in the yarn supply exchange standby position p, has its protrusion 52'' beyond the engagement piece 64' and positioned directly behind it. As a result, as the slider 63 retreats as described above, it is moved back significantly and reaches the yarn feeding exchange position p2 where the yarn can be exchanged between the slider 63 and the arm Y.

In this way, the slider 63 moves the yarn feeding exchange position p2
The yarn supplying bodies 50 that have been retreated are arranged one-to-one for each yarn supplying body.
Stoppers 66^~66 provided in relation to.

(Hereinafter, these will be collectively referred to as stoppers 66) to be stopped at the yarn feeding exchange position p2, but the yarn feeding body 50 that has been kept at the yarn feeding exchange position p2 until now is When the locking of the stopper is released by the above-described retreat of the slider 63, the yarn feeding exchange standby position p is automatically returned by the action of the spring 54. That is, when the yarn feeder 50 that was in the yarn feed exchange standby position p2 retreats, its base punch 52
Another protrusion 52'' on the top surface collides with the stopper 66 and rotates it counterclockwise (as shown by the chain line in FIG. 10). When the yarn feeder 50 is further retracted a little further from the position p2, it engages with the actual locking portion of the stopper 66. However, the yarn feeder 50, which has been held at the yarn feed exchange position p2 by the stopper 66, has its protrusion 52'' at the preset bar. Even if the engagement piece 64' of the stopper 64 is pushed and the yarn is moved back a little from the yarn feeding exchange position p2, the other protrusion 52'' does not rotate the stopper 66 counterclockwise, so the actual position of the stopper 66 is As a result, the yarn feeder 5, which has been at the yarn feeding exchange position p2, is allowed to return to the yarn feeding exchange standby position p2.

The above-mentioned various components installed on the frame Z are covered with a cover 67, and the passive piece 60 and slider 63 are returned to their original positions by springs 68 and 69, respectively. A yarn guide village 70 is installed extending above the hook 53 of the yarn supply body 50 located at the yarn supply exchange position p2. However, now, in the yarn selector Z having the above-described configuration, the electromagnets 55c, 55.

is in an excited state, and as shown in FIG. is set at the yarn feeding exchange position p2, and the hook 5 of the yarn feeding body 50o is attached to the yarn feeding port 71 of arm Y'.
Knitting yarn 2 hung on 3. is being fed, and the yarn feeding body 50c is located at the yarn feeding exchange standby position p, and the bran yarn 2c is hung on its hook 53, and the yarn feeding body 50c is
Both 0^ and 50B are the original position p, which is a position layer in which yarn feeding exchange is not performed.
It is assumed that the knitting yarns 2^ and 28 are placed on the hooks 53, respectively. In the above state, the carriages Y, Y2 move to the left, the arm Y connecting them passes under the hook 53, and the activation piece 59 on the arm Y side moves the passive piece 60 as shown in FIG. When the clock is rotated clockwise, the slider 63 moves back and the preset bar 64 attached to it causes the yarn feeder 50c to become larger.
While being pushed, the yarn feeding body 50D moves to the yarn feeding exchange position p2.
The two yarn supplying bodies 50c, 5 are pushed backwards a little further.
0o are arranged in a line as shown in FIG.

When the arm Y continues to move to the left and the engagement between the actuating piece 59 and the passive piece 60 is disengaged, the slider 63 returns to its original position as shown in FIG. Although the yarn feeding body 5 is kept at the yarn feeding exchange position p2,
At 0o, the stopper 66o is disengaged and returns to the yarn feeding exchange standby position p.

In this way, the knitting yarn 2c hung on the hook 53 of the yarn feeder 50c is fed to the yarn feeder 71 of the arm Y', and the bran yarn 2c is fed by the rightward movement of the arm Y.
is detached from the hook 53 and fed directly to the yarn feeder 71,
As a result, the yarn supply is exchanged from the knitting yarn 2o to the knitting yarn 2c.

Therefore, in this yarn selector Z, if any two of the four electromagnets are energized, then the electromagnets 55 can be excited and the two yarn feeders 501
This allows two of the four cotton yarns 2^ to 2o to be automatically and alternately replaced.

Therefore, if one of the two knitting yarns is used as the base yarn, the other becomes the colored yarn, and the base yarn and the colored yarn can be automatically exchanged. Note that when the relationship between energization and de-energization changes between the four electromagnets 55, the yarn feeder 50 corresponding to the newly excited electromagnet moves from the original position po to the yarn feed exchange standby position p; Then, as described above, the preset bar 64 is pushed to the right, so that the yarn feeder, which is at the yarn feeding exchange standby position p at that time and whose corresponding electromagnet is de-energized, returns to the original position p. It is a return to. The yarn selector Z selects the four knitting yarns 2 as described above.
A~2.

The knitting yarns can be exchanged, but which knitting yarn is used for the configuration of the relevant knitting stage is determined by which of the four grid rows IA to ID on the card 1 is marked. Next, the electrical and electronic configuration from scanning the card 1 to controlling the electromagnets 55^ to 55D will be explained with reference to FIGS. 12 to 15. First, the 12th
To explain the input circuit shown in the figure, the sampling pulses shown in FIG. 13 from the sampling sensor e are separated by a pulse separation circuit PS consisting of a gate network into one for knitting pattern sampling (FIG. b) and one for function mark sampling. It is now separated into two parts (the rainbow in the same figure).

The pulse signal for knitting pattern sampling is input to the write address designation circuit WA including a counter to create a write address designation signal, and the electric signal W(
When the card is scanned along the 0-0' line in FIG. ing.

On the other hand, the /gles m for function mark sampling is input as shift/gles to the shift register SR, and the electric signal from the scanning sensor d related to the scanning of the function mark entry field lf is sent to the mark for each entry grid. The corresponding binary electric signals are stored in the shift register SR sequentially from those in the grid column on the left to those in the grid column on the right.

Among the binary electric signals stored in the shift register SR, the four grid columns IA to 1 on the right side of the function mark entry column lf. Those related to the four filled grid columns on the left side except for the four columns on the left side are stored in the function mark storage memory M old 2, and the ones related to the filled grid lines 1^ to ID on the four right side columns are stored in another function mark memory. This memory ME3 is stored in the memory M town 3 for
What is actually stored in is the four input grid rows 1^~lo
If any one of them is marked, but none of them is marked, new storage in the memory M old 3 is not performed. That is, the pulse for function mark sampling separated by the pulse separation circuit PS (Fig. 13m) is sent to the memory control circuit M including a counter and a delay circuit.
When an output related to mark detection is input to any one of the output terminals corresponding to the four input grid rows IA to lo of the shift register SR, the final function mark sampling pulse is generated. After that, the memory control circuit MC outputs the pulse shown in FIG.

Furthermore, after the last function mark sampling pulse is input, the memory control circuit MC outputs the pulse shown in FIG. 13, which also resets the shift register SR. It has become.

Next, explaining the output circuit shown in FIG. 14, the traveling direction of the carriage Y is detected by a carriage traveling direction detecting means g, and from this detecting means g, the direction of travel of the carriage Y is detected as shown in FIG. As shown, a binary electric signal is output in which "H" and "L" are inverted depending on whether the carriage Y is in the left row or right row.

Further, it is detected that the carriage Y approaches the needle selection end setting members 31 and 3r shown in FIG. ,3r only while driving within the interval range of ,3r.
The effective needle selection range indicating circuit h outputs a signal "H" indicating that the needle is within the effective needle selection range, as shown in FIG. 15D'.

The scanning command circuit SM detects the falling edge of the signal RO representing the effective needle selection range, outputs a pulse, and operates the scanning member control circuit SC to cause the scanning member c to travel. Normally, regardless of the direction of travel of the carriage Y, scanning by the scanning member c is performed every time the carriage moves out of the effective needle selection range determined by the needle selection end setting members 31 and 3r. Further, the card feed command circuit CM detects the rising edge of the signal B representing the effective needle selection range, outputs a pulse, and operates the pulse motor control circuit PC to drive the pulse motor a. Normally, the card is transferred every time the carriage Y enters the effective needle selection range, regardless of the direction of travel of the carriage Y, but as will be described later, the forward movement of both carriages Y, Y2 When implementing a knitting method in which one of the two yarns, the base yarn and the color-selected yarn, is knitted and the other yarn is knitted by a double action to knit the relevant one row, press the button W in advance. When the button W is pressed, the scan command circuit SM outputs a pulse when leaving the effective needle selection range only when the carriage Y is in the right direction, as shown in Fig. 15m. , only at this time scanning is performed by the scanning member c, and the card feeding command circuit C
As shown in Figure V, M outputs a pulse when the carriage Y enters the effective needle selection range only when it is moving to the left, and card 1 is transferred only at that time. It is something that

Now, as mentioned above, fill in the four entry grid rows 1 for thread selection in the function mark entry field lf on card 1.
By scanning ^~lo, each entry grid row 1^
The memory M old 2 for storing the function mark stores the binary electric signal corresponding to the mark D.
Contrary to the case of memory, the input grid array lo
It is designed to be performed in the order from 1^ to 1^. That is, the pulse from the pulse generator PG is ANDAN
D.

It passes through it only when it is open and is counted by the counter CT, and the counted value is converted into code by the decoder DC,
Each time the count value of the counter CT advances from 1 to 4, an output is generated from the 1 to 4 output terminals of the decoder DC, and the output of the 1 terminal is AND, which corresponds to the column ID) is supplied with 2
The terminal output of is supplied with the terminal output of C AND2
, the terminal output of 3 is supplied with the terminal output of B and A
The terminal outputs of ND3 and 4 are respectively input to AND4, which is supplied with the terminal output of A.
AND logic is established in the order from AND, to AND4. AND above
o is set after the flip-flop FF is set by the output shown in FIG. 15W of the card feed command circuit CM as shown in FIG. When) OR
Until it is set by the output of , the pulse from the pulse generator PG is passed through as shown in the plate in the same figure.

If the AND logic is established in any one of the above AND and ~AND4, the flip-flop F
F is reset, and as a result, the counter CT stops counting as shown in the plate of the same figure.As a result, the reading of the above-mentioned terminal M old 3 is performed after the card feed command circuit CM generates an output. The process starts in the order of going to the output terminal of A, and continues until there is an output related to reading the mark from the output terminal.

Therefore, when the carriage Y is in the left row, each time it enters the effective needle selection range, the outputs of the four output terminals A to D of the memory M old 3 (K to blood in FIG. 15) are in the order of D to A. Only one of the output terminals that outputs the signal "H" related to mark reading is extracted by AND and -AND4 as shown in the same figure. Electromagnet 55A~55o
The electromagnet control circuit M^~Mo that controls the motor can be operated.

Therefore, also write this in the function mark entry field
The four entry grid rows 1^-lo for yarn selection of f and the four yarn feeders 50A-50.

Regarding the relationship with , as described above, is displaced from the original position po to the yarn feeding exchange standby position P. The counter CT is reset by the memory control circuit MC each time the card 1 is scanned on the right side, and the scanning and feeding of the card is not related to the carriage Y. It can also be reset by pressing the button SB when performing the reset.

However, as mentioned above, the yarn selector Z selects the four knitting yarns 2^
Any two of ~2o can be automatically exchanged by a mechanical configuration in conjunction with the operation of the carriage Y, and the four grid rows 1^ on the card.
For ~lo, mark the respective entry lattices only for the two entry lattice rows corresponding to the two knitting yarns to be used in the knitting of the relevant knitting row among the four rope yarns 2A to 2o. For example, when knitting the entered lattice row in the knitting pattern entry field lf that is the same as the entered lattice row with that mark, 2.
Regarding the actual knitting yarn, when the carriage Y is moved to the left edge of the needle bed X, the yarn feeding is automatically exchanged. By the way, as mentioned in the explanation of the input circuit in FIG.
In the old 2, if the marked lattice row is different from the previous one in the scanning of the relevant row, the memory contents will change, but if they are the same, it will not change, so the knitting yarn used is the same as the previous row. In this case, it is not necessary to mark that stage of the input grid row 1^-ID.

In addition, the button W shown in FIG. 14 was provided on the needle selection device (located on the back side of the plywood of the carriage Y) during the forward movement operation of the carriages Y, Y2, as described above. A needle selection signal is given, and one of the base yarn and colored yarn is knitted according to the needle selection signal, and during the backward movement operation of the carriages Y, Y2, the needle selection signal and the needle selection signal are given to the needle selection device. This is a knitting method in which one row of knitting is knitted by giving a signal with the reversed or upper and lower knitting needle selection patterns, and knitting the other of the ground yarn and colored yarn according to the needle selection signal. When this button W is operated, the knitting pattern storage memory M is read out as follows.

In other words, if the carriages Y, Y2 are knitting yarns by moving to the left and reach the left end of the needle bed to exchange yarns, and the colored yarns are fed to the yarn feeder 71 of arm Y, then In the subsequent right row, ``In order to knit only the marked part of the corresponding entry lattice row in the knitting pattern entry field lp, the binary electric signal stored in the memory ME, has a relationship of ``1'' and ``0''. It is read out as it is without being reversed and is given to the needle selection device as a needle selection signal, so that the color-selected yarns are able to cover the unknitted portion of the ground yarn knitted in the previous left row as if they were left knitted. It is knitted so that it is satisfied, and one knitting stage is knitted. When this first knitting stage is completed and the carriages Y, Y2 are moved to the left in order to knit the next knitting stage, the colored yarn whose yarn feeding was exchanged in the above is still being fed to the yarn feeder 7. To knit this colored thread, read out the old memory M, knitting pattern entry field lp
``1'' of the binary electric signal for the next input grid stage in
”, “0” remains unchanged, and the carriage Y
,,Y2 is moved to the left end of the needle bed to exchange the yarn feed, and when feeding the ground color to the yarn feeder 71 and moving the carriage to the right, the memory M old is read in order to knit that ground color. The relationship between ``1'' and ``0'' of the binary electric signals is inverted for the next grid row to be filled in in the knitting pattern entry field lp, and one knitting row of the next stage is thereby knitted. When the carriage is moved to the left to knit the third knitting stage after this next stage knitting is completed, the ground yarn that has been replaced in the above manner is still being fed to the yarn feeder 71. , In order to knit this ground yarn, read out memory M old 2 and write the binary electric signal '' for the third input grid stage.
This is done by reversing the relationship of ``1'' and ``0'', and when the carriage is moved to the right after replacing yarn feeding and feeding colored yarn, the relationship of ``1↓``0'' of the binary electric signal is reversed. Reading is performed as it is, and one formation stage of the third stage is thereby formed, and the following formations are performed one formation stage at a time in the same manner.
Thus, among the four knitting yarns 2^~2o, the 2 marked in the four grid rows 1^~lo on the power cord 1 are
The two knitting yarns corresponding to the grid rows are knitted with one as the base yarn and the other as the colored yarn.Finally, the pattern corresponding to the knitting pattern on the knitting pattern entry column lp is knitted in one knit. It is possible to knit with a determined knitting yarn by marking the grid rows 1^-lo for each row.

As is clear from the above description, according to the method of the present invention, by selectively applying marks at predetermined recording positions on the same recording medium on which the knitting pattern is recorded and displayed, the knitting pattern is knitted in the knitting stage concerned. By specifying in advance the desired striped yarn in a program, and by reading that mark together with the above-mentioned knitting pattern by scanning by the scanning section, you can create a pattern using multiple knitting yarns prepared in advance, for example, in different colors. Each time the knitting pattern is scanned, the knitting yarn of any color specified in the above program can be automatically selected from among the knitting yarns of any color specified in the above program. Pattern knitting based on the above knitting pattern can be automatically performed.

In addition, the yarn feeder that performs yarn feed exchange with the yarn feeder of the carriage is moved to the non-active position (original position) by the magnetic force of the electromagnet.
The yarn is moved to the yarn feeding exchange standby position, and is moved from this yarn feeding exchange standby position to the yarn feeding exchange position by the mechanical force based on the movement of the carriage, so the yarn feeding exchange can be carried out accurately, even if small, by the operating range of the electromagnetic plunger and the magnetic force. can be done.
