Description

Description: BACKGROUND OF THE INVENTION (Field of Industrial Application) The present invention relates to a mechanism device used when a full warp beam and a member through which a warp is passed are mounted on a loom.

(Prior Art) In a machine setting operation in which a warp beam is mounted on a loom and the warp is passed through a weaving device, the warp is installed before a new warp beam is mounted in consideration of a reduction in the operation time, which leads to an improvement in operation efficiency. Generally, a working means previously inserted into a plurality of through members such as a heald frame and a reed is used. The present applicant has proposed in Japanese Patent Application No. 61-185629 an invention relating to a mechanism device for transporting and transferring a full warp beam and a warp member through which a warp thread is inserted. This apparatus includes a passing member transferring means for transferring a passing member such as a heald frame and a reed, and a warp beam transferring means for mounting a full warp beam on a loom. Warp tension adjusting means for controlling the rotation of the warp beam to maintain the tension of the warp passed through the warp member at an appropriate value is provided. The warp passed from the warp beam to the warp member is excessively tensioned or loosened with the transfer operation of the warp beam transfer means and the transfer member transfer means, thereby causing warp breakage or warp entanglement to occur. Although there is a possibility that the warp beam may be supported, excessive warping and loosening of the warp can be prevented by the warp beam rotation control of the warp tension adjusting means by rotating the friction roller joined to the warp beam.

(Problems to be Solved by the Invention) However, the warp beam rotation control for adjusting the warp tension in the above invention depends on the operation amount control of the warp tension adjusting means by a push button operation while observing the tension or relaxation state of the warp. Therefore, there is a disadvantage in that it is necessary to rely on the skill of an operator to obtain appropriate warp beam rotation control so as not to cause excessive tension and relaxation. In addition, the speeding up of the transfer operation of the warp beam transfer means and the passing member transferring means is a hindrance to performing appropriate warp beam rotation control, and it is difficult to speed up the transfer operation.

SUMMARY OF THE INVENTION An object of the present invention is to provide a mechanism device capable of performing appropriate warp tension control at the time of transfer work without relying on such skilled workers.

(Means for Solving the Problems) For this purpose, in the present invention, a warp beam rotating means capable of rotating the full warp beam on the warp beam transfer means in the forward and reverse directions, and a feed amount and rewinding of the warp of the full warp beam A warp spout amount detecting means for detecting the amount is installed on the warp beam transfer means side, and a rotation operation for controlling an operation amount of the warp beam rotating means based on the warp in / out amount information from the warp in / out amount detecting means. Control means were installed.

(Operation) The warp yarn in / out amount accompanying the rotation of the warp beam is detected by the warp in / out amount detection means, and this information is taken into the rotation operation amount control means. The amount of warp in / out and the necessary amount of operation of the warp beam rotating means are set in advance in the rotational operation amount control means, and when the information taken into the rotational operation amount control means reaches the set warp output, the warp is set. This means that the rotation operation amount of the beam rotation means has reached the required amount. As a result, the rotation operation amount control means stops the rotation operation of the warp beam rotation means, and feed-out or pull-back of the warp is feedback-controlled.

The magnetic displacement detector 63 is provided with each of the detected pins 65 associated with the rotation of the detection roller 64. It detects the approach of 65 and outputs a pulse signal to the transfer control device 3. The detection roller 64 comes into contact with the surface of the warp layer of the full warp beam 45 by the projecting operation of the hydraulic cylinder 57, and if the full warp beam 45 rotates under this contact state, the detection roller 64 rotates. That is, the feed amount and the rewind amount of the warp T accompanying the rotation of the full warp beam 45 are extracted as the number of pulse signals.

The intermediate stop position indicated by the line is set so as to reach the transfer stop position indicated by the solid line in the same figure, and the initial stop position, the full warp beam 45 at each intermediate stop position and the transfer stop position is transferred to the reed 48. The path lengths of the warp yarns T that are reached are different from each other.
That is, it is necessary to pull out and rewind the warp T from the full warp beam 45 in accordance with the displacement of the transfer operation positions of the transfer levers 41 and 42 and the hook members 36 to 39. Therefore, the transfer levers 41 and 42 and the stop times of the hook members 36 to 39 at each stop position, and the pull-out speed or winding of the warp T accompanying the transfer operation of the transfer levers 41 and 42 and the hook members 36 to 39.

That is, the sending-out amount and the rewinding amount of the warp T accompanying the transfer operation are detected, and information on the actual warp-in / out amount is fed back. As a result, the warp adjustment control during the transfer operation can be appropriately performed without relying on the skill of the operator, and the transfer and rewinding of the warp T can be performed even when the diameter of the full warp beam 45 is changed. The transfer operation speed of the hooking members 36 to 39 of the levers 41 and 42 is accurately followed by the transfer operation speed, and the excessive tension and loosening of the warp T are reliably prevented. In addition, by making the peripheral surface of the detection roller 64 made of rubber, the followability to the rotation of the full warp beam 45 is further improved, and the tension control is performed with higher accuracy.

In addition, it is possible to increase the transfer operation speed of the transfer levers 41 and 42 and the hook members 36 to 39 due to the high accuracy.

The present invention is, of course, not limited to the above-described embodiment. For example, by detecting the diameter of the full warp beam 45, the sending-out amount and the rewinding amount of the warp T corresponding to the rotation speed of the friction roller 53 are detected. And feedback control based on such detection is also possible.

(Effects of the Invention) As described above in detail, in the present invention, the operation amount of the warp beam rotating means is controlled based on the actual warp in / out amount information, so that the transfer operation can be performed without depending on the skill of the operator. This provides an excellent effect that the warp tension at the time can be accurately controlled and the speed of the transfer operation can be increased.
