Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a multicolor knitting device for a hand knitting machine, and is particularly suitable as a device for automatically knitting argyle knits and intarsia knits.

``Conventional Technology'' Conventionally, in order to perform argyle knitting (multicolored knitting in which the knitting yarn does not pass to the back side of the knitted fabric) using a hand knitting machine, the following steps were all performed manually.

■ Knit about 10 rows of waste stitches and hang the weight on the knitted fabric.

■ Knit about 6 rows of plain yarn using the ground yarn and place the carriage on the right side.

■ Remove the ground yarn from the tension device and thread opening and place the ball of yarn under the main body of the hand knitting machine. Place the balls of other knitting yarns under the main body of the hand knitting machine.

■ Move the carriage's cam lever to the "slip" position and move the carriage to the left.

■ Set the cam lever to "Argyle" and move the carriage to the right.

■ Look at the pattern diagram and pass the knitting yarn to the left over the spatula of the knitting needles at each section of the pattern, with the right end at the end.

■ After passing all the knitting yarns, hold the ends of each yarn hanging down and the middle of the passed knitting yarn together in your hands, move the carriage, and knit one row.

■ Look at the pattern diagram and pass each knitting thread to the knitting needles according to the pattern of the next row. In this case, start passing the knitting yarn from the side with the carriage, and at the point where it separates from the next knitting yarn, pass that knitting yarn around the knitting yarn on the carriage side from behind to entangle it, and then pass it onto the knitting needles.

■ After passing the knitting yarn to all the knitting needles to be used, hold it together in your hand, move the carriage to the right, and knit the relevant row.

[Phase] For the next row, start passing the knitting yarn from the carriage side onto the knitting needles in the same way, cross the knitting yarns at the points where they separate from each other, then pass them over, and again hold all the knitting yarns together in your hand and move the carriage. Knit one row.

■ Repeat the same steps below.

``Problems to be solved by the invention'' As described above, in the past, knitting was done through repeated and tedious manual operations, which was extremely time-consuming and required skill.

The purpose of the present invention is to set a plurality of knitting yarns of different colors on an arm removably attached to a carriage, and then
To provide a multicolor knitting device capable of automatically performing argyle knitting or intarsia knitting simply by operating a carriage.

``Means for Solving the Problems'' The multicolor knitting device of the present invention has a yarn guide body in which a plurality of yarn guide ports are provided at predetermined intervals on the left and right sides, and can be detachably attached to the front side of the carriage. Attaches to the arm so that it can move left and right. This arm is also equipped with a thread guide moving means for automatically moving the thread guide, and the thread guide moving means moves the thread guide to accommodate the plurality of knitting yarns individually inserted through the thread guide port. An arbitrary one of the knitting yarns is moved so as to be displaced to an intermediate front position of the left and right knitting cams provided on the back side of the carriage. In addition, a yarn feeder is placed at the intermediate front position of the arm at a gripping position for gripping any one of the knitting yarns, and feeds the gripped knitting yarn to the leather on the needle bed and to the knitting needles involved in q-forming. It is attached so that it can be moved to the yarn feeding position. Furthermore, the arm is provided with a yarn feeder displacement means for automatically switching and displacing the yarn feeder between the gripping position and the yarn feeding position.

"Function" A plurality of knitting yarns of different colors are individually inserted through the plurality of yarn guide ports of the yarn guide body and are moved as a whole along with the carriage while being lined up from side to side. The yarn guide moving means moves the yarn guide to the left or right, and then the knitting yarn to be fed to the knitting needles is previously displaced to a position W where it is gripped by the yarn feeder, and the carriage moves the knitting yarn to the needle. If you grasp the knitting yarn with the yarn feeder when it reaches any position on the floor and remove the yarn feeder at the yarn feeding position, the knitting yarn will be automatically fed to any one knitting needle on the needle bed. can.

This state is maintained until the next thread exchange is instructed by the micro combinator.

When the electromagnet 37 is activated again by the next yarn exchange instruction, the yarn supplying body 36 descends as shown in (9), and at the same time the yarn holding section 42a retreats to the inactive position, so that the first knitting yarn 551 The yarn is removed from the yarn holding portion 42a, and is fed to the knitting needle 51n, which is the last yarn feeding target, as shown in the figure (lO). At the same time, the yarn guide body 24 is again moved to the left by (1/3) P as shown in FIG. It hangs on the hook portion 36a. At this time, the first knitting needle 512 for the second knitting yarn 552 is at a position close to the left of the yarn supplying body 36. Also,
The first knitting yarn 551 is fed to the knitting needle 511 to which the first yarn is fed.
It extends from the top to the knitting needle 55n that is the last yarn feeding target.

In this state, when the yarn supplying body 36 and the yarn holding section 42a l><iM are returned, the second knitting needle 512 as shown in the figure (12)
It is lifted by the hook portion 36a of the yarn feeder 36 and held by the yarn holding portion 42a. At this time, the two knitting needles 51 that are a predetermined number of needles to the right (backward in the carriage traveling direction) of the last knitting needle 51n to which the first knitting yarn 55+ has been fed are pushed backward by the knitting cam 11 rearward in the carriage traveling direction. While being moved, it is also pushed up by the push cam 52 at the rear in the direction of travel. The knitting needles 51 that have passed through the push-up cam 52 are connected to the first knitting yarn 55
1 with the hook 51b and move further backward. When the carriage 7 moves (t1), the first knitting needle 552 for the second knitting yarn 552 moves to the second knitting needle 552 as shown in FIG.
When the carriage 7 further slides beyond the lifted portion of the knitting yarn 552, the butt 51a of the knitting needle 552 is released from being pressed down by the push-down cam 12, and the flier 51b returns to the lower fU. The second knitting yarn 552 lifted and held by the yarn holding section 42a is

In contrast to the case of the first to sixth knitting yarns 551 to 556, the yarn wraps around the hook portion 36a on the left side of the yarn supplying body 36 by approximately half a circumference. (22) As shown in the figure, when the yarn feeder 36 rises and returns to its original position, and the yarn holding section 42a returns to the working position, the seventh knitting yarn 557 is transferred to the hook section 36a on the left side (front side in the direction of carriage movement). The thread holding portion 42a is located below the thread holding portion 42a. By moving the carriage 7 in this state, the seventh knitting yarn 557 is fed to the knitting needle 517 that is the first yarn feeding target. Carriage 7 is
When the left and right point setting members 6 move from inside to outside the pattern range, the thread guide body 24 is moved leftward by (1+2/3)·P as shown in the figure (23). As a result, the seventh knitting yarn 557 is attached to the knitting needle 51 at the end of the pattern range.
The yarn is fed to e. The seventh knitting yarn 557 remains lifted by the left hook 36a even after the carriage 7 moves out of the pattern area, and this state is maintained until an instruction is given to replace the yarn in the next knitting stage. In other words, from figure (21), (
23) By the operations up to the figure, the seventh knitting yarn 557 is fed, and the yarn feeding body 36 is then fed to the sixth knitting yarn 556.
The IH level is set to a level where the yarn can be fed, and preparations are made for the next knitting stage.

When the process proceeds from step 105 to step 106 and the base 1m needle is detected, the direction of movement of the carriage is determined in step 107. If the carriage is moving to the right, the process proceeds to step 108 where the up/down counter 64 is counted up. In the case of the left row, the process advances to step 109 and is counted down. After that, in step 110, a plurality of yarn exchange position data related to the previous stage are stored in the amplifier down counter 64.
It is sequentially determined whether or not the content matches the content of . If they match, the process proceeds to step 111 and then to step 112, where it is determined whether the position data corresponds to the last thread exchange, and then whether or not the position data corresponds to the one before the last thread exchange. If neither of these is the case, proceed directly to step 113 and set the electromagnet on flag. If it is the final thread exchange, proceed to step 114, set the final thread exchange flag, and then proceed to step 114 to set the electromagnet on flag. If it is the previous yarn exchange, the process goes to step 115 to set the last previous yarn exchange flag, and then proceeds to step 113. If they do not match in step 110, step 11
The process proceeds to step 6, where it is determined whether or not there is position data for the next rank. If there is, the process proceeds to step 117, and after reading the position data for the next rank from the previous stage yarn exchange data, the process returns to step 110. .

If the step knob 102 is out of the pattern range, the process proceeds to step 118, where it is similarly determined whether or not the empty passage of the carriage 7 is completed, and if it is completed, step 1
Step 19 turns on the motor drive timer 61, and step 120 sets the time constant to, for example, 5 ms.
, 5m5lJ2, a motor drive timer routine (described later) shown in FIG. 13 is entered. Furthermore, in step 121, the pulse loop counter 65 is converted to pitch P of the thread guide port 26 of the thread guide member 24 and set to P (1+2/3), and then the process proceeds to step 122, where the thread guide member 24 is set in the carriage. It is determined whether or not the direction is the same as the direction of movement in step 7. If the direction is the same, the process proceeds to step 123 and sets the thread guide same direction flag, and if it is the opposite direction, the process proceeds to step 124. Set the thread guide reverse direction flag.

As a result, the thread guide body 24 is moved as shown in FIG. 7 (23) when the thread guide body 24 moves from within the pattern range to outside the pattern range. After this, proceed to step 125 and card 3
The data in the next stage above is read by the reading device 4, and the process further advances to step 126, where the card data in the RAM 59 is updated. If empty passage of the carriage 7 is not completed in step 118, the process advances to step 127 and the data on the card 3 is read.

When the PXo routine shown in FIG. 12 is entered from step 105, first, at step 200, interrupts are prohibited until the next operation. After that, the process proceeds to step 201, where it is determined whether the carriage penetration completion flag is set to 7 degrees or not.Then, the process proceeds to step 202, where it is determined whether or not the electromagnet on flag is set to 7 degrees.If both are set, step 2
Proceeding to step 03, the electromagnet 37 is turned on, and the yarn supply body 36 is lowered as described above.

After this, the process proceeds to step 204, where the electromagnet off timer 62
is turned on, the process proceeds to step 205, where the time constant is set to, for example, 181Ils, and after 18IIIs, the electromagnet off timer routine shown in FIG. 14 is entered.

Next, in step 206, the direction of movement of the carriage 7 is determined, and if the carriage is moving to the right, the process proceeds to step 207 to set a motor forward rotation flag, and if it is to the left, the process proceeds to step 208 to set a motor reverse rotation flag. After that, in step 209, it is determined whether the final yarn exchange flag is set. If it has not been set, proceed to step 210 and set the thread guide same direction flag, then proceed to step 213 to turn on the motor drive timer 61, and then proceed to step 214 to set the time constant to 5 ms. , 5IIls later, the motor drive timer routine shown in FIG. 13 is entered. After this, proceed to step 215 and set the pulse loop counter 65 to (1/3) ・P
Set to . As a result, the knitting yarn is wound around the yarn supply body 36 as shown in FIG. 7 (4). Next, the process proceeds to step 216 where the CCP path counter 66
The number of CPs is set to 3 (firmly set), and the state shown in the figure (4) is maintained only while the carriage 7 slides by three knitting needles.

If the final yarn exchange flag is set in step 209, the process proceeds to step 211 to set the yarn guide reverse direction flag, and then proceeds to step 212 to reset the final yarn exchange flag, and then proceeds to step 213. .

When the electromagnet on flag has been reset in step 202, it is determined in step 217 whether the CCP pass counter 66 is 0 or not, and then in step 218 it is determined whether the pulse loop counter 65 is O or not. When the latter becomes 0, that is, when the motor 32 has completely stopped, the process advances to step 219 and C.
The CP pass counter 66 is decremented. When the CCP pass counter becomes 0 in step 220, the process proceeds to step 221, where the motor drive timer 61 is turned on, and then the process proceeds to step 222, where the time constant is set to 5 ms, and after SMS, the motor drive shown in FIG. Enter timer routine. Furthermore, the process proceeds to step 223 to set the yarn guide reverse direction flag. After this, step 224
In step 225, it is determined whether or not the previous thread exchange flag is set, and if the thread exchange flag is set before the last one, the process proceeds to step 225 and the pulse loop counter 6 is set.
Set 5 to (1+1/3) ・P. As a result, as shown in FIG. 7 (8), the knitting yarn held by the hook portion 36a of the yarn supplying body 36 comes off and is held by the yarn holding portion 42a of the yarn holding body 42. . Step 224
If the thread change position is the one before the last, step 2
After proceeding to Step 26 and resetting the previous yarn exchange flag, proceeding to Step 227 and setting the pulse loop counter 65.
Set to (2/3)・P. In this case, as shown in FIG. 7 (20), the last knitting yarn comes off from the hook portion 36a of the yarn supplying body 36 and is held by the yarn holding portion 42a.

After each of the operations in steps 216, 225, and 227, it is determined in step 228 whether or not the needle is the reference knitting needle, and then in step 229 the traveling direction of the carriage is determined. If it is the left row, the process advances to step 230, where the up/down counter 64 is set to O, and then the process advances to step 231, where interrupts are enabled and the process returns.

If the needle is not the basic knitting needle, the process immediately proceeds to step 231. If the needle is the basic knitting needle and the carriage is in the right direction, the process proceeds to step 231 without passing through step 230.

When the motor drive timer routine of FIG. 13 is entered as described above after 5 ms in steps 213 and 221 of FIG. 12 and step 119 of FIG.
After interrupts are prohibited until the next operation at 00, it is determined in step 301 whether or not the thread exchange same direction flag is set. If it is set, the process proceeds to step 302, and if it is reset, the process proceeds to step 303. In either case, the direction in which the carriage is traveling is determined. When the carriage is moving to the right, the process advances to step 304 to set the motor forward rotation flag, and when the carriage is moving to the left, step 3
After proceeding to step 05 and setting the motor reverse flag,
The process proceeds to step 1306, where the motor 32 is first rotated one step forward or reverse, and the process proceeds to step 307, where the pulse loop counter 65 is decremented, and the process proceeds to step 308.
At this point, it is determined whether the pulse loop counter 65 has reached O or not. If it is not O, the process advances to step 311 to enable interrupts, return, and repeat the same operation until it becomes O. In other words, the motor 32 is operated by the number of sets in the pulse loop counter 65 (for example, in the case of step 215 in FIG. 12, only (17', 3) and P)
The thread guide body 24 is moved to the right or left by rotating in the normal direction or in the reverse direction. When step 1308 indicates O, proceed to step 309 and reset the thread exchange flag.
Further, the process proceeds to step 310, where the motor drive timer 61 is reset, and then interrupts are enabled and the process returns.

When the electromagnet off timer routine of FIG. 14 is entered as described above after 18 m5 in step 204 of FIG. 12,
First, at step 400, interrupts are prohibited until the next operation, then at step 401, the electromagnet 37 is turned off, at step 402, the electromagnet on flag is reset to 1, and at step 403, the electromagnet off timer is set. After resetting, interrupts are enabled in step 404 and the process returns.

"Effects of the Invention" As detailed above, the multicolor knitting device of the present invention has the following effects.

■ A thread guide is attached to an arm that is removably attached to the front side of the carriage so that it can move in the same direction as the sliding direction of the carriage, and a thread feeder is attached to this arm to move the thread guide. By automatically moving, any one of the plurality of knitting yarns inserted through the plurality of yarn guide ports is displaced to a position where it is held by the yarn supplying body, and this knitting yarn is After gripping the yarn with the yarn feeder, the yarn feeder can be automatically moved to the yarn feeding position and automatically feed the desired knitting yarn. Can be automatically organized.

■ Since the yarn feeder is attached to the arm at the intermediate front position between the left and right knitting cams, the operations from gripping the knitting yarn by the yarn feeder to feeding the yarn can always be performed at the intermediate position, which is the fixed position of the carriage. It is convenient for carriage operation and the structure can be simplified.

■ Since multiple yarn guiding ports are provided on the yarn guide at a predetermined interval on the left and right sides, multiple knitting yarns of different colors can be passed through each other at a predetermined interval on the left and right sides. Since the mounting direction can be the same as the knitting direction, the knitting yarns do not get entangled with each other, and a large number of knitting yarns can be used.

(2) When hooks are provided on both sides of the yarn feeder, the knitting yarn can be reliably gripped in both directions by the hooks.

■ If the movement of the yarn guide body is automatically performed by a motor and the displacement of the yarn supply body is automatically performed by an electromagnet, the operations can be centrally controlled by a microcomputer.
