(Prior art) In the fabric manufacturing process, abnormal defects often occur in the fabric, such as steps (so-called stop steps) or soiling of the fabric due to the stoppage of the loom due to cutting of the weft threads. . Therefore, it is necessary to pass the woven fabric through an inspection machine and inspect it while sequentially rewinding it.
Conventionally, the presence or absence of abnormal defects such as the stopper has been checked by visual inspection.

(Problem to be solved by the invention) ゛ Therefore, in such a conventional fabric manufacturing process, not only does it require a lot of labor when inspecting the fabric, but also abnormal defects such as stops may be overlooked, making accurate inspection difficult. There was a problem that.

The present invention has been made in view of the problems encountered during the production of conventional textiles, and its technical object is to enable reliable and efficient fabric inspection during weaving.

(Means for Solving the Problems) The present invention is a weaving management system that stores the operating status of a loom in a storage means and reads out the data when inspecting manufactured fabrics to facilitate inspection. As shown in FIG. 1, a portable storage medium 1;

Then, when the data of the stop position read from the storage medium and the count value match, a stop signal is output to the inspection machine. Therefore, the fabric inspection machine will stop at a position where there is an abnormal defect such as a stop step caused by stopping the loom.

(Description of Embodiment) Figure 2 is a block diagram showing an embodiment of the weaving management system of the present invention.
A first length measuring sensor 4, for example a proximity sensor 21, is attached to obtain a signal corresponding to the weaving length of the loom 2. The length measurement sensor 4 is a sensor that generates a pulse every time the loom 2 weaves a predetermined length, for example, 20 m+m, and its output is sent to the central processing unit (hereinafter referred to as CPU) 23 via the input interface 22 of the data writer 6. given to. The input interface 22 is given a stop signal each time the loom 2 stops during weaving, and the manual input section 24 receives input from the manual input section 24, for example, if there is dirt such as oil during weaving. A manual stop input 24a to be operated when the substance is attached;
A write input 24b and a reset input 24c for writing data to the storage medium when weaving is completed, etc., the signals being input to the C through the input interface 22.
It is given to PU23. A read only memory (hereinafter referred to as ROM) 25 and a random access memory (hereinafter referred to as RAM) 26 are connected to the CPU 23 as storage means. The ROM 25 stores the arithmetic processing procedures of the CPU 23, and the RAM 26 is provided with a temporary storage area for data and an area for holding counters and stop data.

The output of the CPU 23 is given to a portable storage medium 1, for example, an IC memory card 28, via an output interface 27. The data writer 6 includes an input/output interface 22.27, a CPU 23, and a ROM 25. It consists of RAM26.

Next, when inspecting the woven fabric 3, a control means 11 for controlling the inspection machine 7 is connected, and a data reader 9 for reading data from the IC memory card 28 is connected to the control means 11. is connected.

The fabric inspection machine 7 is a device for unwinding and visually inspecting the fabric in order to check whether there are any abnormal defects such as stops in the fabric. Each time it is returned, the second length measurement sensor 8, for example the rotary encoder 31 in this embodiment, is connected. The encoder 3
The output of 1 is given to the input interface 32. Further, a card reader 9 is connected to the human power interface 32. The card reader 9 reads the data by inserting the IC memory card 28 in which the data is held when the weaving of the loom 2 is completed, and the read data is sent to the CP via the input interface 32.
Given to U33. Also connected to the input interface 32 is a manual input section 34 that provides manual rewinding power. A ROM 35 and a RAM 36 are connected to the CPU 33 as storage means. ROM35 is CPU33
, and the RAM 36 has a temporary storage area for data and an area for a counter.

Further, the CPLI 33 provides a stop signal to the inspection machine 7 via the output interface 37. Further, a display 38 and a printer 39 are connected to the CPU 33 as output means.

Next, the operation of this embodiment will be explained with reference to the flowchart shown in FIG. First, when weaving, the IC memory card 28 is attached to the card writer 6 and weaving is started. Then, a pulse is given from the length measurement sensor 4 every time a predetermined length is woven, and this signal is given to the CPU 23 via the input interface 22. CPU2
3 waits for an input from the length measurement sensor 4 at step 41 in FIG. 4, and increments the counter in the RAM 26 if there is an input (
Step 42), it also waits to see if there is a stop signal 9 manual input part number from 164a2 or manual input part 24 (step 43.46), and if these inputs are received,
The count value of the counter in the RAM 26 is held in the data area of the RAM 26 (step 45), and it waits to see if there is a write input or clear input from the CPU 23 or the manual input section 24 (steps 46 and 47). If there is no input, the process returns to step 41 and the same process is repeated.

In this way, when the loom stops before the loom finishes weaving, or when it is deemed necessary due to oil etc. adhering to the fabric, by manually inputting it, the counter value at that time can be changed to It will be stored as data in the data table of the RAM 26. Then, at the time when weaving is completed, a write signal is inputted from the manual input section 24. In this way, step 4 will be executed from step 46.
Proceeding to step 8, the stop data in the RAM 26 and the final count value of the counter are written into the C memory card 28. After that, if a clear input signal is given from the manual input section 24,
The counter and data area of the RAM 26 will be cleared (step 49).

Next, the operation on the data reader side will be explained with reference to the flowchart shown in FIG. When the operation starts, the process first proceeds to step 51, in which data in the IC memory card 28 is read into the RAM 36.

At this time, the final count value at the time of completion of weaving of the fabric 3 woven by the loom is simultaneously read into the counter of the RAM 36, and the process proceeds to step 52, where an input is received from the encoder 31 connected to the fabric inspection machine 7. If there is an input, proceed to step 53,
Decrement the counter in RAM36. The process then proceeds to step 54, where it is checked whether the counted value of this counter matches the stop data read from the IC memory card 28. If they do not match, the process returns to step 52 and waits for input from the encoder again. In this way, while operating the fabric inspection machine 7, the counter in the RAM 36 is decremented by the input from the encoder 31 every time it is rewound by a predetermined length, and it is checked whether it matches the stop data. If it matches the stop data, the process proceeds from step 54 to step 55, where a stop signal is output to inspection fabric a7 via the output interface 37. By doing so, the unwinding will be stopped at the same position as the weaving position where it stopped during weaving, and the operator can visually inspect the condition of the surrounding weaving steps.
The necessary processing can be performed. When the process is finished, a check is made to see if a rewind input is given. If there is this input, the process returns to step 52, waits for an input from the encoder 31, decrements the counter, and continues rewinding until the next stop position is reached. In this way, the inspection machine can be stopped at all the positions where it stopped during weaving, as well as at the positions where the user has given a stop signal if deemed necessary, and can visually inspect the condition of abnormal defects such as stopping steps. The necessary processing can be performed. In addition, using the display unit 39 connected to the CPU 33 and the printer 39, it is possible to display the number of stop rows, etc. that occurred during weaving of the fabric, and depending on the degree of abnormal defects of the woven fabric, such as the number of stop rows, The quality of the product can be displayed or printed.

(Effect of the invention) Therefore, according to the present invention, when weaving, the number of pulses obtained from the first length measurement sensor is counted by the first counting means of the data writer, and a stop signal is given from the loom. The current count value is written to a portable storage medium such as a memory card. At the time of inspection, the storage medium is attached to the data reader and the inspection machine is operated. Then, when the length measurement pulse from the second length measurement sensor attached to the inspection machine is counted by the second counting means and matches the stop signal data held in the storage medium, The inspection machine is stopped. Therefore, the fabric inspection machine automatically stops at a position where an abnormal defect such as a stop step may occur due to a stop during weaving, and a visual inspection can be performed at that position. Therefore, there is no need to constantly visually check the fabric during operation of the fabric inspection machine, the fabric inspection process can be extremely simplified, and the unwinding speed during fabric inspection can be increased. Furthermore, since the degree of abnormal defects in the woven fabric, such as the number of stops, can be accurately recognized based on the stop signal, it is possible to easily identify the grade of the woven fabric.
