Description

The present invention includes an opening device that can electrically control individual movements of a plurality of rib frames, and the vertical position of each rib frame for each loom cycle is set as one repeat of the weaving structure. The present invention relates to an opening pattern setting device used in a loom that drives the opening device according to an opening pattern to operate the frame.

In a loom equipped with an opening device (for example, an electronic dobby opening device, an electric opening device, etc.) that can electrically control individual movements of a plurality of rib frames, the opening device is driven according to a preset opening pattern. Is done. Along with this, each heel frame is driven to move in the vertical direction, and an opening is formed in the warp to perform weaving (for example, Patent Document 1). In addition, an opening pattern consists of a combination of drive patterns of each heel frame for forming a target fabric structure.

The opening pattern is set, for example, as shown in FIG. In the illustrated example, twelve sash frames (hereinafter, the most woven side sash frame is referred to as a first frame, and the subsequent sash frames are referred to as a second frame, a third frame,. ) Shows the setting state of the opening pattern for the loom that weaves. Specifically, the illustrated opening pattern has a plurality of setting states related to the position (the highest position / the lowest position) of each frame (first to twelfth frame) for each opening step (= weaving cycle). It is shown in a matrix over the opening steps. Therefore, each row in the opening pattern shown in the figure indicates the driving pattern of each heel frame that proceeds in units of weaving cycles.

The opening pattern as described above is created by an operator who creates (edits) the opening pattern and is set in the setting device on the loom side. Also, the creation of the opening pattern by the operator is performed using an opening pattern setting device. For example, the operator can display the opening pattern on the display screen of the opening pattern setting device as shown in FIG. In the editing screen displayed in (2), an operation for setting the position (the highest position / the lowest position) of each frame for each opening step is performed.

More specifically, the creation of the opening pattern is performed by changing the display mode of the square frame corresponding to each frame for each opening step. In the example of FIG. In each opening step, a setting is made such that the display mode of the square frame corresponding to the eaves frame set at the highest position is changed to distinguish from the display mode of the eaves frame set at the lowest position. The opening pattern set in this way is displayed in a different manner for each rib frame when it is set to the highest position and when it is set to the lowest position. The relationship between the patterns is easily visible. Note that the change of the display mode of each square frame described above is performed, for example, by placing the cursor on the square frame and operating a button.

Incidentally, as the above-described opening pattern setting device, in addition to a display device provided on the loom (for example, a display device having a touch panel type display unit, etc.), as will be described later, It is conceivable that the opening pattern is created using a “personal computer”) or the like and is read and set in a setting device on the loom side via a storage medium (memory card or the like) or via a LAN.

The creation of the opening pattern as described above is performed prior to the start of weaving as one work of the weaving preparation process. On the other hand, as a weaving preparation process, a warp used in the weaving is also passed through the wrinkles of the used frame. Normally, the opening pattern creation work and the warp threading work through the reed are performed by different operators.

In the operation of passing the warp through the reed, the operation of passing the warp drawn from the warp beam through the reed of the corresponding reed frame according to its position and type is performed. In this warp threading operation, there is a difference in the warp thread (specifically, the warp thread is passed through a cocoon of a cocoon frame different from the cocoon frame to be originally passed), and the drive pattern set by the opening pattern is originally If the hook frame to be passed is different from the hook frame that is actually passed through, the texture of the woven fabric that has been woven will be different from the target structure. Further, depending on the opening pattern, a warp appears in the woven fabric, and the quality of the fabric is significantly deteriorated. Therefore, in the operation of passing the warp through the reed, it is necessary to pass each warp accurately through the reed of the corresponding reed frame.

However, sometimes the above-described warp threading is caused by an operator's mistake. In this case, as described above, the passing of the warp impairs the quality of the woven fabric, and if it is discovered, correction is necessary in relation to the opening pattern. However, the work of passing the warp through the heel requires a great deal of time and effort. Therefore, it is a heavy burden on the operator to redo this, and it takes time and reduces the operating rate of the loom. Therefore, as another countermeasure, it is conceivable to change the opening pattern. That is, for example, when all the warps to be passed through the heel of the heel frame A are passed through the heel of another heel frame B, the drive pattern of the heel frame A and the drive pattern of the heel frame B in the opening pattern are different. In addition, the drive pattern of the frame B is reset in the column for setting the drive pattern of the frame A in the opening pattern, and the drive pattern of the frame A is set in the column for setting the drive pattern of the frame B instead. Thus, there may be a case where the above-mentioned problem of the fabric quality can be avoided.

When it is possible to cope with the change of the opening pattern as described above, it is preferable to deal with the change of the opening pattern when comparing the rethreading of the warp with the change of the opening pattern and considering the burden on the operator. I can say that. However, in the conventional opening pattern setting device, in order to change the created opening pattern, it is necessary to perform a complicated operation of once erasing the set driving pattern and then resetting it. Therefore, even if the opening pattern is changed, time and labor are still required, even if it is not as high as re-passing the warp. In particular, the opening pattern is set for one repeat of a woven structure composed of a plurality of weaving cycles, but when the number of weaving cycles for one repeat is large (in the case of dobby weaving, it takes several thousand picks). In some cases, the time and labor required for the above-described change work are very large.
JP-A-8-311741

Accordingly, an object of the present invention is to provide an opening pattern that can facilitate the work in changing the opening pattern, such as replacing the drive pattern in frame units, reduce the burden on the operator, and shorten the time for the changing work. It is to provide a setting device.

Based on the above problems, an opening pattern setting device of the present invention is an opening pattern setting device for a loom as described above, and a display capable of displaying the set opening pattern on a display screen; Control means for enabling an opening pattern to be changed on the display screen of the display, and the control means is a pattern set for each of two arbitrarily selected frame frames for the set opening pattern. It has a function to replace the.

According to the opening pattern setting device in the loom of the present invention described above, when the opening pattern is changed as described above, it is only necessary to specify two hook frames to be changed, and the driving set for each hook frame. Patterns are automatically replaced. Therefore, the opening pattern can be changed easily and in a short time.

In addition, the above-described change of the opening pattern is not limited to the case where the warp is threaded as described above, and an opening pattern for another fabric is created by changing the already created (set) opening pattern. It is also used when Specifically, some woven fabrics are woven with an opening pattern in which two or more rivet frame drive patterns are replaced with each other with respect to an already created opening pattern. In this case, instead of creating a new opening pattern from the beginning, using the created opening pattern and replacing the drive pattern described above, the opening pattern for the fabric can be created quickly. And it can be done easily.

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

1 to 3 show an embodiment of the present invention. In the following examples, a personal computer is used to create and change an opening pattern, which is transferred via a storage medium (such as a memory card). An example of setting in the setting display device on the loom side will be described. Therefore, in this embodiment, a combination of a display (corresponding to a “display device”) 41, a personal computer main body (accurately, including a pattern creation program (software) executed on the personal computer main body) 42, a keyboard 43, a mouse 44, and the like. Corresponds to the opening pattern setting device 40, and the personal computer main body 42 corresponds to the control means (FIG. 3). However, the device for creating the aperture pattern and the device for changing the aperture pattern are not necessarily the same device. That is, when creating an opening pattern using a personal computer as described above, if the opening pattern is changed by another device (for example, a setting display device on the loom side), this other device is the present invention. This corresponds to the opening pattern setting device.

The opening pattern created by the opening pattern setting device 40 and stored in the storage medium MC is inserted into the reader 21 in the setting display device 20 on the loom and read through the storage medium MC, and then through the CPU 23. The memory 22 is set for storage.

The opening pattern stored in the storage device 22 is displayed by the operator operating the input device 25 and issuing a display request command from the input device 25 to the CPU 23, so that the CPU 23 reads and displays the opening pattern stored in the storage device 22. It can be displayed on the device 24.

Furthermore, the opening pattern memorize | stored in the memory | storage device 22 is output to the main control apparatus 10 via CPU23 according to the request | requirement from the main control apparatus 10 of a loom, and the main control apparatus 10 respond | corresponds to each weaving cycle according to the opening pattern. Every time, a signal corresponding to the selection state (selection state of the highest position or the lowest position) of each collar frame 30a is output to the opening device 30. Then, the opening device 30 moves each hook frame 30a up and down at a predetermined timing based on a signal from the main control device 10.

An example of creating (editing) the opening pattern on the display 41 of the opening pattern setting device 40 will be described below.

First, the operator displays a pattern editing screen 50 as shown in FIGS. 1 and 2 on the display screen of the display unit (display) 41 by the personal computer main body 42 as the control means. The pattern editing screen 50 shown in FIGS. 1 and 2 shows a state in which an opening pattern has already been set (however, in the drawings, only a driving pattern of a part of the frame is drawn, and other patterns of the frame are drawn. The driving pattern is omitted).

The illustrated pattern editing screen 50 will be described in more detail. First, a portion where the square frames 51 are arranged in a matrix on the left side of the screen (hereinafter referred to as “mass frame portion 55”) is a portion for setting an opening pattern. The numbers in the number field 52 attached to the upper part of the square frame portion 55 indicate the numbers of the collar frames 30a corresponding to the columns of the square frames 51. That is, the column of the mass frame 51 to which the numeral 1 is attached indicates the drive pattern of the first frame, and the column of the square frame 51 to which the numeral 12 is assigned indicates the drive pattern of the twelfth frame. Yes.

The numbers in the number field 53 attached to the left side of the square frame portion 55 indicate the step number of the opening pattern. The step number of the opening pattern indicates the order of opening operations that proceed in units of one weaving cycle. Accordingly, the row of the mass frame portion 55 indicates the vertical position (selected state) of each heel frame 30a when the warp T is opened for each weaving cycle.

In such a pattern editing screen 50, the creation of the opening pattern, that is, the setting of the drive pattern of each heel frame, is set to the highest position or the lowest position when the warp T is opened for each heel frame for each opening step. This is done by confirming whether or not the frame is placed and changing the display mode (display color, etc.) of the square frame 51 corresponding to the eaves frame set at the highest position.

For example, in the case where a personal computer is used to create an opening pattern as in the present embodiment, the display mode is changed according to the frame 51 where the mouse pointer (not shown) is to be changed by operating the mouse 44. This can be done by clicking on the square frame 51. Instead of this, a cursor (not shown) is displayed on the square frame portion 55 and the square frame to be changed by moving the cursor with the cursor movement button 62 or the cursor key of the keyboard 43 as shown in FIG. 51, the display mode is changed by operating the upper position specifying button 63a and the lower position specifying button 63b (FIG. 4) or operating a specific key to which the position specifying operation of the keyboard 43 is assigned. It may be performed.

Next, the opening pattern changing operation in the case where there is a difference in the warp passing as described above in the warp passing operation in the weaving preparation process will be described. In the following, a case where the warp T that should be passed through the heel of the seventh frame is mistakenly passed through the heel of the first frame and the warp T that should be passed through the heel of the eighth frame is passed through the heel of the second frame. State. The opening pattern changing operation is performed on the display 41 of the opening pattern setting device 40.

As a change of the opening pattern to cope with the above-described warp threading, the drive pattern of the seventh frame and the drive pattern of the first frame of the already created opening patterns are replaced, An operation of exchanging the drive pattern and the drive pattern of the second frame is performed. Note that this drive pattern replacement operation is executed by a program set in the control means (personal computer body) 42.

In changing the opening pattern, the worker first reads the created opening pattern stored in the control means 42 and displays it on the pattern editing screen 50 on the display 41. Next, the “replace frame” button 54 in the “command” column on the right side of the screen is operated. Thereby, the control means 42 executes the program for drive pattern replacement. Along with the execution of this program, first, the frame replacement setting screen 70 shown in FIG. 1 is displayed on the pattern editing screen 50 of the display device 41.

Next, in this state, selection of the frame for replacing the drive pattern is performed. In the present embodiment, it is assumed that the seventh frame and the eighth frame, which are the warp frames through which the warp passed through the first frame and the second frame should be passed, are selected as the selection frames. This selection of the frame is performed by, for example, clicking on the frame number shown in the number field 52 to change the display state (color, etc.) of the column corresponding to the frame number. The frame is selected. In addition, when selecting multiple frame frames, not only the method of clicking each frame number, but after clicking one frame number and then dragging horizontally, multiple frame frames can be selected. Can also be selected. However, selection of the selection frame is not limited to the above-described method, and can be realized by various methods such as selection by inputting a frame number.

When the selection frame (seventh and eighth frames) is selected as described above, “7-8” is displayed as the selection frame on the frame replacement setting screen 70. Subsequently, the selection frame and the frame that replaces the drive pattern are designated. In the example shown in the figure, the frame number of the hull frame designated as the replacement destination frame is input to the input field 71 of “frame to be replaced” on the setting screen 70.

In the illustrated example, not all of “1” and “2”, which are the frame numbers of the first and second frames whose drive patterns are exchanged with the seventh and eighth frames, are input, but only the frame number “1” is input. By inputting, not only the drive pattern of the first frame but also the drive pattern of the second frame can be replaced at the same time. In other words, when replacing the drive patterns of a plurality of continuous fence frames, it is possible to omit inputting the frame numbers of all the fence frames designated as the replacement destination frames, and the frame No. By designating only one small one, the drive patterns of the plurality of frame frames are automatically replaced. In this case, the control means 42 recognizes the number of replacement destination frames from the number of selection frames as the selection frame, and selects a selection frame that replaces the drive pattern from the number and the frame number input in the input field 71. to decide. However, it is not always necessary for the control means 42 to have such a function, and all the frame numbers of the cocoon frames designated as the replacement destination frames may be input to the input field 71.

Then, after selecting the selection frame and designating the replacement destination frame as described above, by operating the “Confirm” button 72 on the setting screen 70, the drive pattern of the seventh frame and the drive pattern of the first frame are changed. While being replaced, the drive pattern of the eighth frame and the drive pattern of the second frame are replaced, and the opening pattern is changed to that shown in FIG. When the drive patterns are exchanged in this way, the program for exchanging the drive patterns by the control means 42 is completed, and the opening pattern changing operation is completed.

In the illustrated example, the “cancel” button 73 on the frame replacement setting screen 70 is used when the frame number input in the input field 71 is changed, and the cancel button 73 is operated. As a result, the frame number once input is deleted, and a new input becomes possible.

Further, as a function of the control means 42, an error message can be displayed when an unused frame is designated as a replacement frame. For example, in the example of FIG. 1, it is assumed that “16” is input in the input field 71 while the number of frames used is twelve. In this case, the control means compares the number of frames used with the value in the input field 71 (replacement destination frame No.), and if the number of frames used <the value in the input field 71, “exceeds the number of frames”. An error message such as "Value cannot be entered" is displayed. Even if the number of frames used is greater than or equal to the numerical value in the input field 71, an error message similar to the above is displayed when the number of replacement destination frames exceeds the number of frames due to the number of frames to be replaced.

In the above embodiment, the opening pattern is created using the personal computer 40 outside the loom, and the opening pattern is changed using the same personal computer 40, but the present invention is limited to this. Instead, the device for creating the opening pattern and the device for changing the opening pattern may be different devices. For example, the opening pattern may be created by the personal computer 40 outside the loom, and the opening pattern may be changed by the setting display device 20 on the loom side. In this case, the setting display device 20 on the loom side corresponds to the opening pattern setting device in the present invention, and the CPU 23 functions as a control means.

The present invention is not limited to any of the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.
