Description

FIELD OF THE INVENTION The present invention relates to a method for centrally controlling a plurality of looms.

Conventional technology Conventionally, the control data (rotational speed of the loom drive motor, number of driving, warp thread tension, weaving density, etc.) is attached with a symbol indicating the fabric specification, and this control data is registered in advance for each fabric type. In addition, by specifying a symbol indicating the fabric specification for a certain fabric, the necessary control data is transmitted to all the loom, and the central control device for the loom is configured to be set automatically. is there.

Problems of the Prior Art and Objects of the Invention In such a conventional device, the registered data is
Generally, it is the average data that can be commonly used for all units. For this reason, if there are variations in characteristics peculiar to each loom, the loom does not operate as expected with the registered average data. This is a problem of the prior art.

Therefore, an object of the present invention is to provide a centralized control method for a loom that can effectively operate a plurality of looms even if each loom has a characteristic variation.

Therefore, according to the method of the present invention, standard memory control data for controlling the loom and its data content, that is, a unique style number indicating the fabric specification are stored in advance in the memory of the host computer, and The standard control data of No. 1 is corrected according to the variation in the characteristics of each loom, and the corrected specific control data is stored with the weaving base number in addition to the style number. So, the host computer, on a loom, with a style number,
When control data is specified, the presence or absence of that data is determined in the control data search process, and when there is control data with the loom number of the loom, instead of the standard control data, the loom-specific The control data is transmitted to the corresponding loom.

By such a method, even if there is a variation in the characteristics of each loom, control data considering the variation in the characteristics is sent from the host computer to each loom, and flexible and effective centralized control can be performed.

Examples Hereinafter, the method of the present invention will be described in detail with reference to the drawings.

First, FIG. 1 shows the configuration of a centralized control device for a loom to which the method of the present invention is applied. In the figure, a host computer 1 is provided with a CPU 3, an input / output keyboard 4, a display 5, a memory 6 in which various control data and the like are stored, and a communication control interface 7, which are mutually connected by an internal bus 2. Then, the plurality of looms 8 are controlled based on the control data transmitted from the host computer 1 via the communication line 9.

In the apparatus configured as described above, the memory 6 in the host computer 1 stores average or standard control data such as the number of revolutions of the driving motor of each loom 8, the number of driving, the warp tension, and the like. These control data are stored together with a unique style number indicating the fabric specification.

Next, FIG. 2 is a diagram showing an example of this standard control data, and the style number is, for example, “12345.
6 ”. Further, the rotation speed “600”, the driving count “50”, the warp tension “300”, and the like are control data that are target values for the weaving control of the loom.

In addition, in the memory 6 in the host computer 1, in addition to the standard control data of a certain style number as shown in FIG. 2, the variation of the characteristics of each loom 8 corresponding to the above style number is considered. Then, the corrected control data is stored with the style number and each loom number (loom number) added.

FIG. 3 shows an example of the corrected control data. Here, the target value of the rotation speed is corrected from the standard value "600" to the eigenvalue "550". For example, the loom number “012” is added to the end of the style number “123456” in the modified control data so that the standard control data can be used for weaving.

FIG. 4 is a diagram showing a style number list. A large number of style numbers are added according to the fabric specifications, and the standard control data corrected according to the characteristic variation of each loom 8 includes the style number and a 3-digit loom number at the end thereof. "012" and "055" are attached.

Here, for the control data unique to each loom 8, the standard control data corresponding to the style number registered in the host computer 1 is read, the control data is corrected by the operator, and then the loom number is added. Then, as the corrected control data, it is registered or the loom is taken offline, the optimum value is obtained while actually changing the data by operating the loom, and then the changed control data is brought online to the host computer 1. The control data unique to each loom 8 is corrected by a method of reading and re-registering these control data with a style number and a loom number.

FIG. 5 shows the operation sequence of the host computer when implementing the method of the present invention.

The host computer 1, after starting the program,
First, enter the loom number, for example, "12", to which the control data is to be sent in the step, then enter the style number, for example, "123456", that indicates the control data in the step, and then in the step, the style as shown in FIG. Read the number list. Next, in the read style number list, it is judged whether or not there is data with the loom number “012” input with in the style number input with Here, if the applicable loom numbered style number is, for example, “1234556012”, the CPU 3
The corrected control data as shown in FIG. 3 will be read. In addition, when the judgment result in the step is No,
That is, when the corresponding loom numbered style number is not registered, the process proceeds to the step, where the corresponding style number, that is, the style number "12345 shown in FIG.
6 ”control data is read. At this time, the data content is
The standard control data is as shown in FIG.

After that, the process proceeds to step, and the control data read in step or step is transferred to the corresponding loom 8. After that, if the operator modifies the control data, it will be necessary to rewrite the control data.
In the step, the control data peculiar to the loom 8 is received, and in the next step, it is judged whether or not the transfer data previously transferred is different from the received data. If they are different, the step is received. The data of the style number + the loom number is written in the data. If the data is not different, no writing will be done. In this way
This series of programs ends.

As a result of the above operation, each loom 8
The control data unique to each loom is transmitted, and each loom 8 can weave under optimum control based on each of the transmitted control data.

As described above, in addition to the standard control data, according to the present invention, for the loom that does not work well with the standard control data due to the variation in the characteristics between the looms, the control data unique to the loom. Is automatically transmitted and set. Therefore, according to the present invention, it is possible to perform flexible centralized control without reducing the operating rates of a plurality of looms even if the looms have characteristic variations.
