Abstract

(57) [Summary] [Purpose] If a yarn breakage occurs over time, it prevents malfunctions due to poor contact or adhesion of dust, etc., and reliably detects a yarn breakage regardless of where the yarn breaks. [Structure] A guide 5 of a plate body for supporting the yarn 6 upward in parallel with the front reed is provided laterally on the warper main body 4 at regular intervals in the rear part of the front reed 3. A shaft 7 is laterally provided between the front reed 3 and the guide 5 in parallel with the front reed. A base end of a dropper 9 having a small hole 10 formed at the tip thereof is rotatably inserted into the shaft 7. Dropper 9
A sensor 11 is provided on the side of the.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a warp machine for winding a warp yarn around a beam from a creel and a device for detecting a yarn breakage of the warp yarn during winding.

[0002]

[Prior art]

 Conventionally, in the thread breakage detection of the warper, an electric contact is provided between the creel and the front roller, and the dropper comes into contact with the contact at the time of thread breakage to stop the warper. However, with this configuration, malfunctions often occur due to poor contact or the attachment of dust, etc., resulting in poor workability, and when thread breakage occurs at the rear position past the front roller, the space between the creel and the front roller is reduced. Has a drawback that the device does not work because the thread tension is always applied.

[0003]

[Problems to be solved by the device]

 From the above point of view, the present invention has no malfunctions due to poor contact or adhesion of dust etc. at the time of yarn breakage of the warper, and the device operates even if the yarn breakage occurs at any place. An object of the present invention is to provide a yarn breakage detection device that can stop the machine.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the device of the present invention is provided with a guide on the warper main body for supporting the yarn upward in parallel with the front reed at regular intervals at the rear part of the front reed. A shaft is laid side by side parallel to the front reed, and the base end of the dropper having a thread locking part at the tip is rotatably supported on the shaft and a sensor is installed on the side of the dropper. It is characterized by being present.

[0005]

[Action]

 The operation of the device of the present invention will be described. In the dropper, the thread is engaged with the thread locking portion and the thread is supported upward by the guide. Therefore, the tip of the dropper does not hang down but is rotated upward. However, if thread breakage occurs, the tension of the thread will be lost and the tip of the dropper will rotate downward due to its own weight. When the dropper rotates downward, the sensor installed on the side of the dropper detects the dropper and stops the warper.

【Example】

 An embodiment of the device of the present invention will be described below with reference to the drawings. FIG. 1 is a mechanical view showing an embodiment of the device of the present invention, and FIG. 2 is a side view showing another embodiment of the dropper. Thus, in the figure, 1 is a creel, 2 is a front roller, 3 is a front reed attached to the front part of the upper surface of the warper main body 4, 5 is a rear part of the front reed 3 at regular intervals, and is attached to the front reed 3. It is a plate guide that is erected in a horizontal direction in parallel. The guide 5 prevents the thread 6 from hanging down and supports the thread 6 upward, and may be a shaft instead of a plate.

Reference numeral 7 denotes a shaft horizontally provided between the front reed 3 and the guide 5 in parallel with the front reed 3, and both sides thereof are fixed to a bracket 8 provided on the main body 4. Reference numeral 9 denotes a thin piece of dropper having a base end rotatably inserted into the shaft 7, and the droppers 9 are arranged in multiple rows in the direction of the shaft 7. The material is alumina, which has high insulation properties and prevents wear.

The tip of the dropper 9 is formed with a thread locking portion provided with a small hole 10. The thread 6 is inserted into the small hole 10, and the thread 6 engages on the guide 5. Therefore, the tip of the dropper 9 is Is fixed in a state of rotating upward, and is prevented from rotating downward. Reference numeral 11 is a side of the dropper 9, a sensor installed at a height that can detect when the dropper 9 is rotated downward, 12 is a rear reed, and 13 is a winding beam. FIG. 2 shows another embodiment of the dropper 9, in which a hook-shaped thread locking portion 14 is formed at the tip instead of the small hole 10.

[0009]

[Effect of device]

 According to the present invention, when a warped yarn breakage occurs, the sensor senses the dropper's droop and stops driving the warper, so unlike the conventional electric type, contact failure and dust adhesion can occur. There is no malfunction due to. In addition, since the detection device is provided at the rear part of the front reed, when the thread breaks at the rear part of the front reed, the tension of the thread is lost, the dropper can detect the droop, and the thread breaks in front of the front roller. However, when the thread passes the front roller, the tension of the thread disappears, and the thread tension can be detected.
