BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drive control device for a loom which drives a warp delivery beam and a woven cloth take-up roll.

[0002]

2. Description of the Related Art Among the conventional methods of exchanging warp beams, first, when the warp yarn is cut between a dropper device and the warp beam and a previous warp beam and a new warp beam are exchanged, first of all, It is necessary to loosen the tension, tie the front warp and the new beam warp by a warp tie device, and move the knot of this rear warp from between the heald's mail and reed wing to the weave. Then, after this, the loom is restarted. At this time, when the knot of the warp passes through the reed wing, the dropper, and the male part of the heald, the warp must be moved so that the knot of the thread is not caught in those parts. Therefore, normally, in this work, one operator operates a switch for moving the winding and feeding device on the control device side of the loom, and another one monitors the running state of the warp and the knot is a dropper or a heald. Hit the warp and give vibration so that it can pass through the mail part successfully. Therefore, two or more workers are required to replace the warp beam.

Therefore, as disclosed in Japanese Utility Model Publication No. 3-45978, a portable transmitter and receiver for wirelessly controlling the feed motor and the take-up motor of the loom are provided. The control device can be connected via a connector, and the worker takes this transmitter and receiver to the loom for exchanging the warp beam, connects the receiver to the control device of the loom, and the worker While watching the knot of

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show an embodiment of the present invention. A loom to which the drive control device of this embodiment is applied is
As shown in FIG. 1, the warp yarn 12 wound around the delivery beam 10 is fed to the weft inserting portion 18 via a guide roll 14, a dropper 15, and a heddle 16. In the weft inserting section 18, the weft 20 is weft-inserted by a weft-inserting device (not shown), so that an opening 22 of the warp 12 is formed and a reed 24 is provided so as to be swingable. The woven fabric 26, which has been weft-inserted, beaten, and woven, is wound around a winding roll 28 via a guide roll 30, and then is wound around a cross roll 32 by a predetermined amount via a guide roll 31.

A delivery motor 34 and a worm 35 for deceleration are provided on the delivery beam 10 side, and a worm gear 36 and a worm 35 provided on the delivery beam 10 are provided.
Are in mesh. A winding motor 38 and a worm 39 are provided on the winding roll 28 side and mesh with a worm gear 40 attached to the winding roll 28. Each loom is provided with a control device 42 for controlling its operation and the like, and an operating portion 44 of this control device 42 is provided at a predetermined position. Further, drive amplifiers 45 and 47 for driving the feed motor 34 and the take-up motor 38, respectively, are provided in the control device 42.

Next, the operation and operation of the drive control device for the loom according to the present invention will be described. First of all, the delivery beam 1 of the loom
When 0 is exchanged and the knot 12a is formed on the warp 12, after that, as the weaving proceeds, the knot 12a is sent to the weft inserting section 18 through the dropper 15 and the heddle 16 and passes between the reeds 24. To do. Therefore, the worker sends the transmitter 46 and the receiver 4 to the loom where the sending beam is exchanged.
8 and connect the receiver 48 to the controller 42 via the connector 70. Then, holding the transmitter 46, the user goes to the position where the knot 12a of the warp 12 is located, presses the delivery switch 51, and rotates the motors 34, 38. Furthermore, at this time, the worker gives vibration to the warp 12 so that the warp 12 can easily pass through the dropper 15 and the like. Further, the sending speed is adjusted by the speed adjuster 59 as needed.

As for the control signal at this time, when the sending switch 51 of the transmitter 46 is pressed, a predetermined sending control signal is issued from the command section 52, and this control signal is modulated by the sending circuit 54, and the antenna 56 is sent. The transmitted control signal transmitted from is received by the antenna 66 on the loom and is input to the receiving circuit 60 via the connector 70. The receiving circuit 60 demodulates the control signal, outputs it to the drive control unit 62, and outputs the drive signal to the drive amplifiers 45 and 47 via the connector 70. As a result, the delivery motor 34
And the winding motor 38 rotates.

As a result, the operator can replace the warp beam by himself, and since the antenna of the receiver is not provided, the portability and handleability of the transmitter 46 and the receiver 48 are improved. is there.
