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 in particular to a control method for a jacquard mechanism that can speed up fabric pattern production and improve operability during weaving. Regarding the method.

[Prior 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 selects the opening of the warp threads of the loom according to the perforation pattern of the patterned paper. It is used as a control mechanism for weaving different patterns.

However, when changing the weaving pattern, it is necessary to replace the pattern paper, which is a complicated process, and when trial weaving various patterns, the process from punching the pattern paper to completing the actual weaving is very difficult. It's taking quite a long time.

[Purpose of the invention]

The purpose of the present invention is to improve these conventional drawbacks, eliminate the need to replace the pattern paper when changing the weaving pattern, speed up the process from punching the pattern paper to weaving even in the case of pattern trial weaving, and improve the weaving process. The object of the present invention is to provide a method for controlling a jacquard mechanism that reduces pattern production time and improves operability during weaving.

(Summary of the Invention) In order to achieve the above object, the Jacquard mechanism control method of the present invention provides a method for controlling a Jacquard mechanism according to the present invention.
The needle selection information for the specified weaving start gap, stop gap, and number of repetitions is sequentially sent to the solenoid corresponding to the number of stitches of the Jacquard mechanism in synchronization with the timing pulse generated when the poker of the Jacquard mechanism rises. A feature of the present invention is that, after the poker is suctioned and held in that position or dropped, the meter reading is activated and, at the same time, the outputted needle selection information is displayed in a patterned pattern.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing an example of the configuration of an apparatus for carrying out the method of the present invention, and FIG. 2 shows the operator of FIG. 1.

FIG. 3 is a front view of the console.

In FIG. 1, 1 is a magnetic recording device, 2 is a computer, i.e., a processor equipped with each part of arithmetic control, storage control, and input/output control, and 5 is an input/output control section of a computer 2, a solenoid driver 4, and a Jacquard. An interface unit 8 connecting the mechanism 0 and the loom 7 is an operator console.

As shown in FIG. 2, the operation surface of the operator console 8 includes, from the left, a power switch, operator control input switch, reset switch, start switch, loader switch 9, test switch,
Return switch, jump switch, exit switch, data connection lamp 17, operator control warning lamp, computer warning lamp 18, ready lamp, end lamp and crossing ALED 14, preference A L, B

Start over switch 11, stop over switch 12, repeat/
A switch 13 is provided.

The needle selection information is created by an automatic jacquard pattern generation system.

By pressing the loader switch 9 of the operator console 80, the needle selection information recorded on the paper tape, floppy disk, etc. is recorded in the magnetic recording device l. The magnetic recording device 1 may be a 4TB disk, a fixed disk, etc., but here the latter is used because of its high speed and large capacity.

The needle selection information is controlled so that the warp thread appears in the on position and the weft thread appears 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. The weaving conditions can be set using a magnetic recording device.
This is done by specifying the needle selection information recorded in the needle selection information using the Samir switch 10. Since the magnetic recording device 1 can record a plurality of pieces of needle selection information, any one of them can be selected.

For example, a certain pattern among multiple patterns is l121! When weaving, by specifying a repeater who determines how many times the needle selection information is to repeat the starting point, stop point, and range concave, it is possible to weave only an arbitrary range of the pattern. . For this reason,
On the operator console δ, the Samir switch 11 specifies the weaving start point, the Samir switch 12 specifies the weaving stop point, and the Samir switch 13 specifies the weaving repeat.

After setting these weaving conditions, weaving is started. One period's worth of needle selection information is input from the magnetic recording device 1 to the computer 2 in advance. As mentioned above, since the needle selection information is specified and recorded in the magnetic recording device 1, the specified needle selection information causes the magnetic recording device 1 in which the first data of the needle selection information is recorded. For example, track and sector numbers on fixed disks can be identified. However, the track and sector numbers of the fixed disk where the specified starting data is recorded cannot be identified, so
Input one cycle of data in sequence and check the accuracy of the data. L in the operator console 8 in FIG.
ED14. In lδ, 16, the Etsurin style is always displayed, so if you input one period at a time, you can check the correspondence between the sector number and the Etsu number.

When the start point specified by switches 11, 12, and 13 is reached, the track and sector are recorded.

When the machine pulse that is generated from the jacquard mechanism 6 when the poker rises and is periodically inputted is inputted via the interface section 3, one period's worth of needle selection information is synchronously inputted. Interface part 3, solenoid
The output is sent to the solenoid group δ corresponding to the jacquard mechanism 60 through the 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 Koshiya included in the needle selection information is output. to LBD14, the taste plate to LED], 5, and the pattern paper shop to LED16,
Display each.

In this way, pattern weaving corresponding to the first patterned paper is started. After the needle selection information is sent sequentially via the interface section 3, if the needle selection information reaches the specified stop pure black, the next needle selection information will start from the track or sector that has already been recorded. data will be input.

If the thread breaks or a malfunction occurs on the way, by pressing the return switch 19 on the console 8, black will be displayed on the LEDs 14, 15 and 16 sequentially going back to the previous cycle. Return to pure black at the failure point, and restart from that pure black after repair.

Furthermore, when receiving machine pulses from the jacquard mechanism 6, if needle selection information is not input from the magnetic recording device 1 to the computer 2 for some reason, a stop signal is output to the loom 7, and a data delay lamp is displayed. 17 is displayed.

Also, if an error occurs when inputting data from the magnetic recording device 1 to the computer 2, a stop signal is sent to the loom 7.
is output and the computer alarm lamp 16 is displayed.

Repeat the above operations until the specified repeater is satisfied.

The jacquard mechanism 60 ro number adopted in this example is 134
It is 4. The time for outputting needle selection information to 1344 solenoids is approximately 700 μs, which is several hundred times faster than the operating speed Q of the Jacquard mechanism 6, which is 3 Sec (in the case of 20 rpm).

〔Effect of the invention〕

As explained above, according to the present invention, when controlling the jacquard mechanism, a needle selection signal is generated from the computer and the corresponding pure black is displayed on the console, so weaving pattern production can be speeded up. At the same time, it is possible to improve the operability during weaving, and the effect is great.
