Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a thread number reading device that reads the number of threads in a row of threads during warping, for example, and stops the machine when an excess or deficiency in the number of threads is detected.

[Conventional technology]

Generally, the number of threads during warping is checked by a worker reading the number of threads while touching each thread one by one at the start of warping, but this reading process requires a considerable amount of effort. Misreading the number of threads is likely to occur due to the fatigue of reading the number of threads repeatedly, and this misreading occurs frequently when the thread is yarn-dyed.

In addition, the thread breakage stop device during warping and knitting is
This device uses the dropper type or optical sensor type, and is installed in areas with large vibrations or air flow, resulting in frequent malfunctions and low device reliability.

On the other hand, if a knitted fabric is knitted using warp yarns with an excess or deficiency in the number of yarns, the knitted fabric will be damaged, causing a decrease in the quality of the product.

[Problem that the invention attempts to solve]

As mentioned above, checking the number of yarns during warping is important and needs to be done accurately, but there is a limit to the ability of the workers, and it is difficult to require them to do more than that.

This idea was made in view of the above points,
We provide a thread count reading device that accurately reads the number of threads during warping, etc., and stops the machine when an excess or deficiency in the number of threads is detected, thereby preventing damage to the knitted fabric and increasing production efficiency. The purpose is to

[Means for solving problems]

The yarn number reading device of the present invention includes a guide path arranged above the yarn row in a direction across the warped yarn row, and a sensor for detecting the yarn movably arranged in this guide path. , and a control device which calculates the number of threads in response to the signal from this sensor and stops the machine according to the calculated value.

[Effect]

In the yarn number reading device of the present invention, the number of yarns in the warped yarn row is recorded in the control device,
The number of threads in the thread row is measured by a sensor that moves along the guide path, and the measured value is sent to the control device, where it is compared and calculated, and if the preset numbers do not match,
The machine is stopped by a signal sent from the control device, thereby preventing the production of defective knitted fabrics.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a yarn row warped by a warping machine (not shown), and supports 3 and 4 for supporting guide rods 2 are erected on both sides of this yarn row 1. The guide rod 2 is located above the thread row 1 and across the thread row. The guide rod 2 is provided with a movable laser type sensor 5 for reading the number of threads. Further, an air cylinder 6 is arranged on the supports 3 and 4 so as to be located parallel to the guide rod 2. A laser type sensor 5 is connected to this air cylinder 6, and by operating the air cylinder 6, the laser type sensor moves along the guide rod 2.

On the other hand, the laser type sensor 5 is connected to a control device 7 via a line (not shown). The number of threads in the thread row 1 to be measured is preset in the microcomputer incorporated in the control device 7. The control device 7 compares and calculates the signal sent from the laser sensor 5 with a preset thread count value, and when the signal value differs from the preset value, outputs a control signal (not shown). Stop the machine.

On the other hand, a laser type sensor 5 is provided at a suitable portion of the inner surface of the supports 3 and 4 facing the laser type sensor.
A shock absorber 8 is provided to receive the impact.

When the air cylinder 6 is actuated, the laser type sensor 5 moves along the guide rod 2 in response to this and measures the number of threads in the thread row 1. This measurement signal is sent to the control device 7, where it is compared with a preset thread count value, and if it is detected that the measured value is different from the preset thread count value, that is, the thread count is too large or too short, A signal is issued to stop a machine (not shown), such as a knitting machine, thereby preventing the formation of defective parts in the knitted fabric.

FIG. 3 shows another embodiment of the present invention, in which a video camera 10 is used as a sensor, and a light source 11 is arranged below the thread row 1 to illuminate the thread row. Incorporated. The signal from the video camera 10 is sent to the control device 12, where it is compared and calculated, mechanically reads the number of threads, and measures the color of the threads in the thread row. According to this, the number of threads of each color and the total number of threads in the thread row are displayed on the control device 12, and if a thread in the thread row breaks, the machine can be stopped and it is possible to know which thread in the thread row has broken. I can do it.

[Effect of idea]

As described above, according to the present invention, the number of threads in the thread row is detected by a sensor and the machine is stopped in response to this signal, which eliminates malfunctions during use and prevents the occurrence of defective products. It has the effect of being preventable.
