Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for controlling warp shedding commands in a dobby loom.

Conventionally, as a method of controlling the weave pattern of a woven fabric in a dobby loom equipped with a dobby,
- There are some that use something composed of cards, etc. For example, in the case of a wood card, as shown in Figure 1, the peg (1) corresponds to the data signal and the wood card (6
) is implanted in the required position. This wood card (6) is connected by the upper and lower chains (21 (2X) and rotated by the cylinder r-(3) shown in Fig. When (1) lifts the fish lever (4), the rod (5) at the tip lowers and the hook (7) supported by the rod (5) also lowers.

When the hook (7) is lowered, the knife (
8), the hook (7) is pulled to the right, and the Jack Lenos (9) are also moved to the right, so that the wire In attached to the Jack Lenos (9) is attached to the heald frame. is lifted and the warp threads are opened.

If the peg is not implanted, fish reno-
Since (4) also remains in state 1, the hook (7) is not caught by the knife (8) and the heald frame is not lifted.

Dobby looms have a large number of heddle frames, and the opening of the warp threads threaded through these heddle frames is controlled by the presence or absence of the pegs (1) of the wood card (6), allowing the production of various types of fabrics. . In this case, if you try to weave a fabric with a large structure, the number of wood cards (6) will be enormous, and the size of one wood card is 14 m in width x 235 m in length.
m x thickness 1011111, this is 400-600
When it comes to books, you'll need a card sink. Furthermore, it takes a long time to plant and connect the pegs to the wood cards, which increases the material and labor costs for the wood cards.

In recent years, it has been recognized once again that it takes a lot of effort to change the wood card as well as the changing of the wood fabric, which has become particularly popular in high-mix, low-volume production.

On the other hand, if the fabric structure is wood card, it has its own limitations, and even if you want to create a large fabric structure on a certain board, it is practically impossible. If a plurality of textile structures were to be arranged arbitrarily in the fabric, the number of cylinders would be required, which would make the device complex and large, making it very expensive and requiring a complicated control method. Also, peg wear,
There were drawbacks such as malfunctions due to missing parts, etc., and high-speed rotation was not possible due to the control method's rotational movement structure. There is not much difference in paper card dobby machines, except that they are lighter than wood cards and the length of the cards is shorter.

The present invention is aimed at solving the above-mentioned drawbacks of the warp shedding command device in the conventional R-Bee loom. , the opening rotation information is stored in the data pack and sent to the dobby control device, which outputs the heald frame opening instruction signal from the control device to control the shedding drive of each heald frame.

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

FIG. 3 is a Zoroku diagram showing the outline of this embodiment.

A is a program system department that creates the opening pattern information of the fabric structure and heald frame, and is equipped with a computer, a printer, and 70
Consisting of a Tubi disk unit and a pack writer, when arbitrary pattern information data is entered into the computer by key operation, it is stored as encoded data in the data pack inserted into the nozotsu writer, and is also written to the floppy disk at the same time. . This is because encoded data for a single item, for example, one type of fabric, is stored in the data pack, so to store a number of pieces of information together, write it on a floppy disk.

It is also possible to print out the data sheet from an IJ printer in order to check whether the created information has been entered correctly.

B contains the encoded data entered in the program system section of A. The contents of the encoded data stored in the data storage are the complete organization data, the number of repetitions of the complete organization, and the number of repetitions of the complete organization. Complete organization data such as star door P-response, entre shuttle day loom stop data, and complete organization name data are encoded.

C has Ppee control section f, control unit, p
It consists of a y-ive unit and is operated and controlled by inserting the data track B in which the encoded data is stored into a socket provided in the control unit! be.

The drive unit is installed by removing part of the existing Dobby cylinder and using the mechanism that previously held the cylinder. A push button ζ that is moved by an electric signal is placed on the part corresponding to the wooden card with a strange sound.
- is arranged and there is one that drives the fish reno.

Once the data pack has injected encoded data into the Dobby control, it can be removed from the Dobby control and stored for providing data to other Dobby controls.

In this way, by converting the data into fabric/co-P, it is possible to weave a plurality of woven structures at arbitrary positions and at arbitrary lengths, and a new woven structure can be woven at the desired position of the fabric.

The ORT screen in the program system section ζ This shows the diaphragm diagram. Operate the keys according to the shank diagram. Data programming can be done with easy operation. It takes 4 to 2 hours compared to conventional work. Can do one task. In addition, all inconveniences caused by wood cards, etc. are eliminated, and since the data is injected using a data pack, the work is as simple as attaching and detaching the data pack, improving productivity and allowing continuous trial weaving. This is something that can be done.
