Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a method for controlling a loom by weaving data.

[Conventional technology]

For example, the official gazette of Japanese Patent Laid-Open No. 59-211658 discloses a central host CPU.
From the control data to each loom.
Here, each loom has its own machine number and
While confirming the machine number of the transferred control data, the control data is sequentially decoded. In this way, the machine number is determined during the data transfer process, so that the control data is reliably sent to the target loom.

However, even if the control data is reliably sent to each loom, if a work-in-progress product such as a warp beam or a weft cone is mistakenly set on the loom, the target weaving becomes impossible. Conventionally, such a state can only be visually determined and the operation of the loom cannot be automatically prohibited, resulting in unintentional weaving.

[Object of the Invention]

Therefore, an object of the present invention is to confirm the weaving data of a given work-in-progress and a weaving condition of the work-in-progress set for each loom in the control process of the weaving machine, and to make an appropriate check according to the confirmation result. It is to be able to perform various treatments.

[Means for Solving the Invention]

Therefore, the present invention inputs the weaving data indicating the identification code of the work-in-progress to the terminal of the loom, and then detects the identification code of the work-in-progress actually set on the loom side as the weaving condition. Weaving conditions are compared, and only when they match, the loom can be operated, and vice versa.
When they do not match, the operation of the loom is automatically prohibited.

〔Example〕

This embodiment illustrates a method of controlling a loom by centralized control. The centralized control device 1 controls the control units 3 of a plurality of looms 2. And the central controller 4
The data bus 6 is connected to the terminal 5 connected to each control unit 3.
Connected by.

On the other hand, the control unit 3 or the terminal device 5 is connected to the detector 7. These detectors 7 read the weaving condition of the work in progress set on each loom 2, for example, the identification code 10 for setting the weaving condition of the warp beam 8 or the weft cone 9, and the number of rotations of the loom, the feeding speed, Parameters such as the winding speed, the warp yarn density, the opening amount, and other mechanical conditions are detected and sent to the control unit 3. The identification code 10 is written or affixed to the axis of the warp thread beam 8 or the side surface of the weft thread cone 9 by a bar code or other identification mark.

The central control unit 4 has a built-in memory in which weaving data necessary for the operation of each loom 2 is stored in advance. When the weaving data is requested from the terminal device 5 of each loom 2, the central controller 4 reads the necessary weaving data from the address of the machine number in the memory while confirming the machine number. Transfer to the corresponding terminal device 5 via the bus 6. here,
From the weaving data, the terminal 5 decodes necessary weaving data such as the number of revolutions of the loom, the type of yarn, the warp yarn density, and sends it to the control unit 3. In this way, the control unit 3
Will operate the loom 2 in an optimal operating state according to the weaving mode based on the transferred weaving data.

By the way, the terminal 5 executes a program for confirming the weaving data of the work in progress sent from the central control device 4 and the weaving condition of the work in progress set on the loom 2 during the series of control operations. Run.

FIG. 2 shows the order of the program.

First, the terminal device 5 confirms that the transfer of the weaving data is completed,
The confirmation program is started, the identification code 10 of the warp thread beam 8 and the weft thread cone 9 is first read by the detector 7, the weaving conditions are decoded from the contents, and then the transferred weaving data and the weaving conditions after the decoding. Compare with and check if they match or do not match.

When the contents match, the terminal unit 5 generates an operation command signal to the control unit 3 and, at the same time, transfers a data confirmation signal to the central control unit 4 through the data bus 6.

When the weaving data and the actual control conditions do not match, the terminal device 5 immediately issues an operation prohibition command to the control unit 3 and lights the lamp or the like on the loom side to display the operation prohibition state. The disagreement state is transferred to the central control unit 4 through the data bus 6. Therefore, the discrepancy between the control data and the weaving condition can be confirmed not only on the loom 2 but also on the display of the central control device 4. Here, the worker takes appropriate measures to match them and then gives a start command to the loom 2 to start weaving.

[Other Examples]

In the above embodiment, the weaving data and the weaving conditions are confirmed by the terminal device 5, but such a confirmation function may be performed by the control unit 3 configured by a microcomputer or the like. When the centralized control method is not used, the weaving data is input to the terminal device 5 by an operator or a memory card.

〔The invention's effect〕

In the present invention, the weaving data of the work-in-process and the weaving conditions of the work-in-process actually set for each loom are confirmed in advance by the identification code, and the operating state of the loom according to the confirmation result,
Alternatively, since the operation prohibition state is set, unintentional weaving can be reliably prevented, and when the weaving data and the weaving conditions do not match, appropriate measures can be taken immediately.
