Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a saving count aborting device in a command saving device for a program sheet for a knitting machine.

In order to control the knitting operation of a flat knitting machine, a mark is placed in a predetermined field on a program sheet, the presence or absence of the mark is searched optically or mechanically, and the knitting machine corresponding to the mark is operated accordingly. , when performing the same operation repeatedly and in succession, if marks indicating the operation are not placed consecutively on the program sheet, but only the first mark is placed,
It is known to prevent the program sheet from becoming unnecessarily long by using a saving device that performs the same operation in response to instructions from the mark again from the next course onwards.

The device of the present invention interrupts the continuous repetitive operation during continuous striping machine operation under the same conditions using the above-mentioned saving device, and performs knitting operation according to the mark written at the next address on the program sheet. It was designed to do this.

An example of implementation of the device of the present invention will be described with reference to the drawings. 1 is the program sheet, and on both sides there are perforations 2,
2, the central part of which is vertically divided into several rows of compartments, and each compartment is used as a part for marking each part of the knitting machine to give instructions as to whether or not to operate it.

The types of marks include a position mark 3 for determining the stop position of the program sheet, an origin mark 4, a forward rotation mark 5, a reverse rotation mark 6, a jump (2 pitch) mark 7, a saving setting mark 8, and an end point (return) mark. ) Mark 9 and other mark fields are provided for operation instructions for each part of the knitting machine, such as instructions for high and low distance operation of the carriage. In this embodiment, four types of saving count setting marks are provided: 1 time 8a, 2 times 8b, 4 times 8c, and 8 times 8d. Also, the distance between perforations 2 and 2 is equal to that of the perforation.

The gram sheet is divided into multiple rows, and the first column is named No. 1 and No. 2, which are used as the command mark positions for each course during formation. For example, column section 4 is a field in which a source point mark indicating a starting position is attached. Therefore,
It is only attached to the first, or number 1, section of the wisteria row. Note that the address and the number of courses in the organization are different. This is because, if a save count setting mark is attached to the same address, for example, a one-sided flea area, a predetermined number of courses will continue to be compiled at the same address. The above-mentioned marking of each section is performed by crushing the prayer marks at predetermined positions on the transparent program sheet with an opaque mark 10.

Apply adhesive to one side of the colored sheet with marks 10' on it, and place it on a 4-inch sheet that is large enough to cover the designated position.
Cut it into pieces and paste them in place on the program sheet. Further, instead of using the small pieces as described above, a predetermined position of the program sheet may be painted opaquely with paint. A transparent protective sheet (not shown) is placed over the mark 10 made as described above to prevent the mark 10 from coming into contact with the outside. The program sheet 1 with the mark 10 placed at a predetermined position is introduced into the retrieval device by engaging the perforations 2, 2 at both ends thereof with the sprocket wheels of the retrieval device of the knitting machine.

The search device has a detection member consisting of a combination of an arc tube and a light-receiving element in each column section, and when the part marked 10 on the program sheet reaches between the arc tube and the light-receiving element, the light from the arc tube is received. This initiates a predetermined operation of the knitting machine in order to block access to the tube. Assume that knitting starts from the starting position of the origin mark in column 1 and 4 of program sheet 1, and knits up to 1 charged area. On the program sheet, the 15th battery has a mark in the normal rotation mark column, so it is forwarded by one pitch of normal rotation. After the knitting machine performs the knitting operation based on the commands in each column of address 15, the program sheet is moved one address and the one mirror address is searched. The mark on the 1-phrase knitting area also rotates forward by 1 pitch, so after the knitting machine operates according to the commands in each column of address 16, the program sheet moves to 1.
Ishigameji is searched.

For the one-way crab pattern, a mark is placed in the reverse mark column 6, and at the same time, it is a one-pitch feed of the reverse point, and at the same time, all the columns of 1, 2, 4, and 8 of the saving count setting mark 8 are marked.

For this purpose, all of the light receiving elements 21a, 21b, 21c, 21d corresponding to the saving number setting marks 8a, 8b, 8c, 8d sensed by the search by the search device are input to the data input 22a of the preset counter 22 for the saving device.
, 22b, 22c, and 22d are all set to the diurnal potential. In this embodiment, as explained earlier, the saving count setting value 8a is 1 time, 8b is 2 times, 8c is 4 times, and 8d is 8 times.
Since it is 15 times, if the total number of times saved is marked, the number of times saved is 15 times. On the other hand, the light receiving elements 21a, 2
Signals sensed by 1b, 21c, and 21d become inputs to the OR circuit ORI, and the output thereof becomes one input to the AND circuit ANDI. Here, following the movement of the carriage of the knitting machine, there are pulse signals of ■■■■■ that are sequentially generated when the carriage approaches the abutting portion.

The signal {circle around (2)} from this sequential pulse generating circuit becomes the other input of the logic circuit ANDI, and is input to the set side of the count start circuit, thereby setting the Q output at H level. Since the count start state 22e becomes H level, the preset counter 22 internally presets the data 19 immediately before the change as the specified number of times. on the other hand-
The output of the AND circuit ANDI passes through the delay circuit 24 and is given to the count terminal 22f of the preset counter 22 as a count signal, but since the counter has already been set to 15 times and is in the counting state, it is one less than 15 times. The displayed information is displayed using a light emitting diode or the like. The signal ■ and then the signal ■ are given to each designated circuit, allowing enough time for the sequential pulses to pass from the generating circuit to the signal ■, and then the signal ■, and the program sheet 1 is changed from one side to the mark in the reverse mark column 6. A reverse 1 pitch command returns to the 1st home ground.
1 mother address is forward rotation 1 pitch feed due to the mark in the forward rotation mark field 5, and there is no saving count setting, so the logical sum circuit OR
, and therefore the preset counter 22
Since no signal was received at the count terminal 22e of the controller, the set number of times was not minus 13, and the line machine was set up based on the commands in each column of the program sheet for one row, and the program sheet was set for one row. to move to.

When moving to the first field, since 15 savings marks are written in each column of the number of savings setting column 8, an output is generated in the OR circuit OR, and a rectangular wave is input to the count start circuit and the count input.

However, when the S input of the count start circuit 23 terminal is input again, the Q output does not change and data 1 is not sent again, so the number of times that was previously decremented by 1 from 19 countries is decremented by 1 more, and 17 It returns to each column of the address, and after the knitting operation returns to the 1st charged area by the 1st pitch command in reverse direction. In this way, we moved back and forth between the 1-ku electric field and the 1-directional flea area, saving 14 times compared to the 19 times set at the beginning.

Repeat until all of become zero. The drop detection circuit 25 detects that the difference between the set number of times and the executed number of times has become zero, and outputs a signal indicating completion of the saved number of times execution to the OR circuit OR2.

The OR circuit OR2 further transmits a signal to the reset terminal of the count start circuit 23. In response to this, the count start circuit changes the output Q from H level to L level (
(reset). The rectangular wave falling detection circuit 26 that detects the signal from the H level to the L level is activated, and the count end storage circuit 27 is set, and the count end storage circuit switches the command switching circuit 28. In this state, the program sheet is being fed by 1 pitch in reverse on one side, but the signal from the mark side is not connected after the input terminal of the command switching circuit 128 (switched to the forward rotation command setting section 29 side). Regardless of the command at address 17), the program sheet is moved to the 1st flea area by forward rotation and 1-pitch feed, and after that, the following line machine is assembled according to the command specified in the program. . In the above case, address 1 on the program sheet
Between addresses 6 and 17, the command to save the number of times is executed 15 times, and the user goes back and forth between the 1st raid area and the 1st customer area. Let's say you want to advance through the program sheet.

In that case, the saving termination switch 30 is pressed. Then, the saving discontinuation memory circuit 31 is set, and the saving memory circuit 31 outputs a discontinuation command to the input side of the AND circuit AND2. One input of the same circuit AND2 contains the output signal of the OR circuit ORI which becomes H level only at the address where the number of saving times is set, so the program sheet moves to one side of the flea, and the OR circuit ORI goes H level. The command to discontinue is not transmitted to the output of the AND circuit AND2 until the level signal is output, but if the saving number setting marks 8a, 8b, 8c, and 8d are searched, and the saving number setting mark exists, the logical sum When a day level signal is output to the circuit ORI, the output of the AND circuit AND2 also becomes H level, the output of the OR circuit OR2 also becomes H level, the counter start circuit 23 is reset, and the pulse fall detection circuit 26 is activated. ,
The count end storage circuit 27 is set to H level, the command switching circuit 128 is switched to the forward rotation command setting section 29, the program sheet advances one pitch toward the forward rotation side, and the next address is executed. As described above, the device of the present invention converts the output of the circuit 31 that remembers that the switch has been pressed and the output of the OR circuit ORI upon detecting the saving count setting mark into the logic horizontal circuit A.
The counter start circuit 23 is reset by the input to ND2 and the output of the same circuit AND2, and the program sheet is operated in the forward direction through the count end memory circuit 27 and the command switching circuit 28. Even if the user freely operates the saving number abort switch 30 without any conditions when he wants to discontinue his religious service, it is very easy to use because the abort only works after arriving at the address for setting the number of saved times.

That is, since the saving count cutoff point is always the next count setting address, when pressing the cutoff button, the switch can be pressed no matter which course the knitting machine is knitting, and the stop position can be predicted. The device of the present invention can be used to easily create mini-sembles of products, such as on test lines, and when checking the program sheet that has been set for the first time. This is extremely effective when there is no need to check the set number of times.

Claims (1)

[Claims] 1 At predetermined positions on the program sheet that is fed step by step, there are multiple types of basic saving count setting mark fields, a forward rotation mark field that issues a signal to rotate the program sheet in the forward direction, and a reverse rotation mark that also issues a signal to reverse the program sheet. When the presence of a mark is detected by searching each column with a photoelectric element, a signal is emitted, and when a forward rotation mark is detected, the program sheet is rotated one step forward, and when a reverse rotation mark is detected. In a program sheet saving device for a flat knitting machine, the program sheet saving device for a flat knitting machine has a means for reversing the program sheet by one step at a time, and rotating the program sheet forward by one step when the difference between the set value of the number of saved times and the number of executions becomes zero. The output of the saving discontinuation memory circuit set by the output of the switch and the output obtained by detecting the saving count setting mark are input to an AND circuit, and based on the output of the circuit, the output is converted into the program sheet. For a flat knitting machine, characterized in that the program sheet is rotated in the forward direction by one step when an output is generated when a photoelectric element detects a mark in the save count setting column after inputting the input into the means for forward rotation in steps.
