Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a method for controlling a jacquard mechanism, and particularly to a control method for a jacquard mechanism that enables rapid fabric pattern production and improved operability during weaving. It is about the method.

rPrior art] Conventionally, the Jacquard mechanism lowers a dropper needle corresponding to the perforation pattern of the patterned paper, moves the subsequent mechanisms in sequence, and finally perforates the patterned paper while sorting the opening of the warp threads of the loom. It is used as a control mechanism to weave a pattern according to the pattern.

However, in the conventional jacquard mechanism as described above, when changing the weaving pattern, a complicated process of replacing the pattern paper is required, and when trial weaving various patterns, the process of perforating the pattern paper is necessary. There has been a problem in that it takes a considerable amount of time to actually complete the weaving.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and its purpose is to solve the above-mentioned problems in the conventional jacquard mechanism and to eliminate the need for replacing the pattern paper when changing the weaving pattern. Another object of the present invention is to provide a control method for a jacquard mechanism that shortens the time from pattern paper perforation to weaving and improves operability during weaving even when pattern trial weaving is performed.

[Summary of the invention]

The above object of the present invention is to sequentially record needle selection information for specified weaving start stitches, stop stitches, and number of repetitions among the needle selection information recorded in a magnetic recording device by timing pulses generated from a Jacquard mechanism. In a method for controlling a Jacquard mechanism in which output is output to a group of solenoids corresponding to the number of holes in the Jacquard mechanism, needle selection information for the starting point or needle selection information for the following specified number from the starting point is stored in the main memory of the control device. This is achieved by a Jacquard mechanism control method characterized in that the needle selection information recorded in the main memory can be used when returning from a stop position to a start position.

Specific number = (Time required to input needle selection information at the position of the maximum access time of the magnetic recording device) ÷ (Time required to input needle selection information at consecutive positions of the same magnetic recording device) [Embodiment of the invention ] Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

FIG. 1 is a diagram showing an example of the configuration of an apparatus for carrying out the control method of the present invention, and FIG. 2 is a front view of the operator console shown in FIG. 1.

In FIG. 1, ■ is a magnetic recording device such as a magnetic disk device, 2 is a processor equipped with each part of arithmetic control, storage control, and input/output control, and 3 is an input/output control section of the processor 2 and a solenoid driver 4°. An interface connecting the Jacquard mechanism 6 and the loom 7, and 8 indicate an operator console.

As shown in FIG. 2, the operation surface of the operator console 8 includes a power switch, an operator control input switch, a reset switch, a start switch, a loader switch 9. Various switches such as test switch, return switch, jump switch, end switch, data delay lamp 17. Operator control alarm lamp, processor alarm lamp 18. Ready lamp, end lamp,
Etsuto LED14. Echouchi Ha L E D 15. Pattern paper N
Displays such as LED 16 and 1 needle selection information switch 10. Start over switch 11. Stop over switch 12. Each switch of the repeat switch 13 is provided.

Needle selection information is created using the Jacquard automatic pattern generation system. That is, by pressing the loader switch 9 of the operator console 8, needle selection information recorded on a paper tape, floppy disk, etc. is recorded on the magnetic recording device 1. Although a floppy disk device, a fixed disk device, etc. can be used as the magnetic recording device 1, the latter is used here because of its high speed and large capacity.

The needle selection information is controlled so that the warp threads appear in the on position and the weft threads appear in the off position, similar to the on/off setting of the perforation position of patterned paper.

After recording the needle selection information, weaving conditions are set on the operator console 8. To set this weaving condition, set the number of the needle selection information recorded in the magnetic recording device I to the Samir switch 1.
This is done by specifying 0.

Since a plurality of selection information can be recorded in the magnetic recording device 1, any one of them can be selected.

For example, when weaving a certain pattern among multiple patterns,
If the needle selection information specifies the starting point Nu, the stopping point Nu, and the repetition motion that determines how many times that range is to be repeated, it is possible to weave only an arbitrary range of the pattern.

The above-mentioned starting point is specified using the Samir switch 11 on the operator console 8, the stopping No. is specified using the Samir switch 12, and the repetition Na is specified using the Samir switch 13.

After setting these weaving conditions, weaving is started. The needle selection information for one period from the start point Nα to the stop point No. is inputted from the magnetic recording device 1 to the processor 2 in advance. From Na of the needle selection information specified in the above operation, the track and sector of the magnetic recording device 1 in which the first data of the needle selection information is recorded can be identified.

However, since it is not possible to identify the track and sector in which the data of the starting point Nn specified by the above-described operation is recorded, data for one cycle is inputted one cycle at a time to confirm the starting point of the data. The LEDs 14, 15, and 16 on the operator console 8 indicate Etsu Ha, Echiuchi Tsutomu, and Monshi Na.
is displayed all the time, so if you input one period at a time, you can associate it with the sector number.

When the specified value is reached by the above operation, the magnetic recording device! Look at the track and sector number display area of l.
Record the track and sector.

After that, when the machine pulse generated at the rise of the poker and periodically inputted from the Jacquard mechanism 6 is inputted via the interface 3, one period's worth of needle selection information is synchronized with this. Interface 3. The output is sent to the solenoid group 5 corresponding to the number of holes in the Jacquard mechanism 6 through the solenoid driver 4, and after the poker is sucked and held in that position or dropped, the horizontal hand is activated and at the same time the overpass included in the needle selection information is output. Nα to the LEDI/I,
Tsutomu Echouchi to LED 15, and Monshi Na to LEr) 16
are displayed respectively.

When the meandering motion becomes the stop meandering motion designated by the above operation, the next needle selection information will be outputted corresponding to the starting point Nn.

These operations are repeated until Nl1l is satisfied.

If, for some reason, the needle selection information is not input from the magnetic recording device w1 to the processor 2 &; when the machine pulse is received, a stop signal is output to the loom 7 and the data delay lamp 17 is displayed. . Further, if any error occurs when inputting data from the magnetic recording device 1 to the processor 2, a stop signal is output to the loom 7 and a processor alarm lamp 18 is displayed.

Hereinafter, the output timing of needle selection information of the apparatus of this embodiment will be explained based on FIG. In Figure 3, M
P represents a machine pulse, NS represents needle selection information output from the processor 2, and DI represents needle selection information input from the magnetic recording device W11 to the processor 2.

The needle selection information is outputted at the rising edge of the machine pulse MP (k: pattern paper Ha = 1-n) output from the jacquard mechanism 6, and one cycle of needle selection information N5(k) is output to the solenoid group 5. It is something that will be done. For example, when the rotation speed of the magnetic recording device 1 is 24 Orpm, MP(k) is the period T =
It is output at 250m5ec.

The number of openings of the Jacquard mechanism 6 adopted in the device of this embodiment is 1.
344, and the time required to output 1344 bits of needle selection information N5(k) to 1344 solenoids is:
It was about 70θμsec. After outputting the needle selection information N5(k), the needle selection information DI(k+1) to be output next is input from the magnetic recording device 1.

The access time of the magnetic recording device 1 used in the apparatus of this embodiment is a minimum of 2w1lsec, a maximum of 237m5ec, and an average of 77m5ec. When continuously inputting the needle selection information DI(k) from the magnetic recording device 1, it is possible to input the needle selection information DI(k) in several tens of seconds including the output time to the LED etc., which is shorter than the period T of the machine pulse MP(k). is quite short, and there is plenty of time to re-input in case there is an input error in the magnetic recording device 1.

However, when returning from the preset stop point to the start point, the needle selection information D recorded in the magnetic recording device 1
The more I (k), the longer the machine pulse MP
It is possible that it may take longer than the period T of .

Therefore, this problem can be solved by recording the needle selection information NS(+) in the main memory of the processor 2 in advance and outputting it in synchronization with the machine pulse MP(1). In this case, after outputting the needle selection information N S (n) corresponding to over-stop in accordance with the machine pulse M P (n),
The needle selection information DI(2) of the magnetic recording device 1 is input. As a result, it is only necessary to input the signal within a time up to twice the period T.

Furthermore, if not only the needle selection information N5(1) is recorded in the main memory of the processor 2, but also the following specific number M of needle selection information is recorded in the main memory, further speeding up can be achieved. becomes possible.

Specific number = (Time required to input needle selection information at the position of the maximum access time of the magnetic recording device) ÷ (Time required to input needle selection information at consecutive positions of the same magnetic recording device) [Effects of the invention] As described above, according to the present invention, when controlling the Jacquard mechanism, needle selection information for the starting stitch or needle selection information for the specified number from the starting stitch is recorded in the main memory of the control device. The needle selection information recorded in the main memory can then be used when returning from the stop stitch to the start stitch, making it possible to speed up weaving pattern production and improve operability during weaving. This has the following effects.
