Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loom control data changing means, and more particularly to a loom control data changing method capable of improving the operability of a large number of looms by using a memory card. Is.

2. Description of the Related Art In recent years, advanced electronic technology has come to be used for controlling a loom, so that the quality of a product (cloth) has been improved and adjustment has become very easy. On the other hand, the number of control items that need to be set is extremely large, and its operability is a problem.

Therefore, in order to solve such problems, use a memory card, input the control data of all control items to the memory card, and when setting the control data for each loom, all items from this memory card A method has been proposed in which the control data of 1 is sequentially read and can be easily set at one time.

However, in an actual weaving factory, a situation occurs where it is desired to change only a part of the control items.
For example, we do not want to change the weft insertion because it is optimally adjusted according to the yarn type and the characteristics of the loom,
When the quality of the warp yarn is different due to problems in the preparation process and the like, it may be desired to change only the warp yarn tension in accordance with the woven fabric. In such a case, in the method of using the memory card, the method of changing the warp thread tension from the keyboard has to be adopted for all the loom.

As described above, in the conventional method for changing the loom control data and the apparatus therefor, when changing some control items, the keyboard is operated for all the loom to change the control items. It had to be performed, and had a problem of poor operability.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a weaving machine control data changing method and a device thereof that can easily change only a desired control item by using a memory card.

According to the method of changing the loom control data according to the present invention, first, when a memory card used for changing the loom control data is created, a first step of designating an item to be changed in the loom control data and the item to be changed. A second step of inputting control data to be written into, and a skip code for an item not specified in the first step, and an input of a skip code for the specified item in the second step. It comprises a third step of writing control data respectively to create a control data string and a fourth step of writing the control data string to the memory card. Next, using the memory card, the control data of each loom is transferred. When changing, read the control data string from the memory card, and if the read item has the skip code, skip the item. If there is no read skip code, the control data for that item is set in the loom, and the skip and control data are set for all items of the control data.

Effects of the Invention In the present invention, first, when creating a memory card used for data modification, a skipping code is set for items that are not desired to be changed, and control data desired to be changed for items that are desired to be changed without adding a skipping code. To set.
As a result, a data string of each item is created with the presence or absence of the skip code as a mark. By writing the data string thus created in the memory card, one memory card for changing only the control data of a specific item is completed.

Next, when using this memory card to change the control data of each loom, first read the control data written in the memory card, and if the read item has a skip code, set the data in the loom. If the item that has been read does not have a skip code, the control data for this item is set in the loom.

In this way, the control data for only the item to be changed is sequentially changed for each fiber.

Since the conventional memory card method does not specify the skip code, if you change the data of only the item you want to change and input it, the learning function usually corrects the initial data, so you do not want to change the item. However, in the present invention, the data change may occur.
Such a problem does not occur.

Embodiment Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a changing device according to the present invention.

This changing device is provided for each loom. First, a memory card is loaded into the changing device of a certain loom that requires data change, and the memory used for changing data using the changing device of this loom. The case of creating a card will be described.

A card writing unit 3 for writing control data to the memory card 1 in response to a command from the card writing command unit 2 is provided. Also memory card 1
In order to read the control data from the card reading means 5, a card reading means 5 which operates in response to a command from the card reading command means 4 is provided. The control data of the memory card 1 is read by the card reading means 5, and if the read skip code is not designated by the data read skip means 6 described later, the item and the data are transmitted to the memory write means 7.

On the other hand, an item designating unit 8 is provided for designating an item to be changed, and the designated item is input to the memory writing unit 7, the memory reading unit 9, and the data aligning unit 10.

The set value input means 12 is connected to the memory writing means 7, and the data for the item to be changed is input through the set value input means 12.

The input data is stored in the set value storage means 11 via the memory writing means 7. Further, set value storage means 11
The changed data stored in is transmitted to the card writing means 3 via the memory reading means 9 and the data arranging means 10 and written in the memory card 1.

The control device of the loom (not shown) performs necessary control based on the control data of each item stored in the set value storage means 11.

Here, the item designating means 8 can be configured to have function keys corresponding to the number of control items, or can be configured to display a menu of control items for selection.

The set value input means 12 is composed of a keyboard for inputting data of designated items and a display indicator,
The input set value is input to the memory writing unit 7. The memory writing unit 7 writes the data input by the set value input unit 12 into a predetermined storage location in the set value storage unit 11 for the item specified by the item specifying unit 8.

The memory reading means 9 reads the data of the item designated by the item designating means 8 and transmits it to the data aligning means 10.

The data arranging means 10 uses the input data from the memory reading means 9 for the item designated by the item designating means 8 and the predetermined skipping code for the items not designated. To create a control data string. That is, the input data from the memory reading means 9 is written to the designated item (item to be changed) without adding the skip code, and only the skip code is written to the unspecified item (item which is not desired to be changed). By writing, a data string of each control item is created. The control data string thus created is transmitted to the card writing means 3.

Next, writing of control data to the memory card 1 will be described.

When a switch or the like in the card writing command means 2 is pressed, the writing command is transmitted to the card writing means 3. The card writing means 3 writes the data string created by the data arranging means 10 in the memory card 1 in response to the write command. In this way, one memory card 1 in which only the data of the item to be changed is written is completed.

Next, a method of reading data from the memory card 1 for changing the control data of each loom will be described.

First, the memory card 1 created as described above is loaded into a loom that requires data change. When a switch or the like in the card read command means 4 is pressed and the read command is transmitted to the card read means 5, the card read means 5 reads the control data stored in the memory card 1 and skips the data read means. 6 is transmitted. If the data is an item with a data skipping code, the data skipping means 6 skips the data as it is, and if it is an item without a skipping code, the data is read and the memory writing means 7 is executed. Transmit to.

FIG. 2 is an explanatory diagram showing the arrangement of various control data stored in the memory card 1. In the case of this embodiment, only the skip codes, for example, "1" are written in the items A and B which do not need to be changed, and their data are not written. Further, the skipping code is not written in the item C to be changed, for example, “(blank)” is written, and then the data is written.

When such data is input to the data skipping means 6, item A and item B are skipped and item C is skipped.
Is read and transmitted to the memory writing means 7. Then, the data of the item C is written by the memory writing unit 7 in the storage location corresponding to the item C in the set value storage unit 11. In this way, the data of only the item C designated is changed. Then, the control device of the loom (not shown) restarts the necessary control based on the changed new control data in the set value storage means 11.

FIG. 3 is a flow chart for explaining the data changing method according to the present invention. The operation of the present invention will be described below with reference to the flowchart of FIG.

First, a description will be given of a case where the data to be changed is written from the set value input means 12 to the set value storage means 11 when changing the control data. In the command input waiting state (step 301), when the item to be changed, for example, the warp thread tension is designated by the item establishing means 8 (step 302), the pointer is set to the designated item (step 303) and the item setting flag is turned on. (Step 304).

Next, the value to be changed is input by the set value input means 12 (step 305). In this way, the memory writing means 7 writes the input data in the storage location of the designated item in the set value storage means 11 (step 30).
6).

When the data writing is completed, the item setting flag is turned off (step 307).

Next, a case where the data to be changed is written in the memory card 1 will be described.

First, the item designating unit 8 designates an item to be written (step 302). Therefore, the pointer is set to the designated item (step 303) and the item setting flag is turned on (step 304). In response to the write command from the card write command means 2 (step 308), the item setting flag is turned on at this time (step 30).
4) This is detected (step 309), and a data string in which the skip code "1" is written in items other than the pointer is created (step 310).

When the data string is created, the item setting flag is turned off (step 311), and this data string is written to the memory card 1 (step 312). If a write command is issued from the card write command means 2 without specifying an item (step 302), the item setting flag is in the off state, and this is detected (step 309).
All items stored in the set value storage means 11 are written in the memory card 1 (step 312). In this case, the skipping code is not set and the control data of all items are written in the memory card 1 as in the conventional case.

Next, in the case of reading from the memory card 1 (step 313), in response to the read command from the card read command means 4, the card read means 5 causes the memory card 1 to read.
To sequentially read the control data stored therein (steps 314, 317). Then, if the data is not the read skip code, the data read skipping means 6 writes the respective data into the set value storage means 11 via the memory writing means 7 (steps 315, 316). In this way, when changing the control data, whether to skip or set new control data is performed for all items (step 317).

The above-described operation is sequentially executed for all the loom whose control data in the factory is to be unified or changed. As a result, only the specified item is set as new control data. In this way, the setting of the control data to be changed is executed by inserting the memory card for each machine and pressing the read switch once.

In the embodiment described above, when creating a data string to be written to the memory card, for items that do not want to be changed, only the skip code is written, and the data is not written. Instead of this, the data may be written in addition to the skipped code.

Also, the skipping code is set for the items you do not want to change, and the data of the items you want to change is changed, but conversely, the "reading code" is set for the items you want to change, and based on this code The data of the item to be changed may be changed. In the above description, the skipped code is “1”, but from the opposite viewpoint, it can be understood that the read code is “(blank)”.

EFFECTS OF THE INVENTION In the present invention, a skip code is specified for an item in the control data that is not desired to be changed, reset input data is provided only for an item to be changed, and a data string is created to create a memory card. Since it is configured to be stored again in, it is possible to easily change only the control items that you want to unify in the fabric factory.
Therefore, there is an advantage that the weaving factory can be efficiently managed.
