As shown in FIGS. 6 and 7, the load cell 13 sends a weight signal of the fiber winding body 3 to a control computer 35 via a cable 34, and the computer 3
Reference numeral 5 changes the winding speed and the winding time of the glass fiber winding machine 2 according to the weight signal, and adjusts the winding amount of the glass fiber to a set amount. One end of the cable 34 is connected to the connection wiring 13a of the load cell 13 via a terminal 34a fixed to the support bracket 14, and the cable 34
Is connected to a terminal 34b fixed to the support plate 24.
Is connected to the connection wiring 35a of the control computer 35 via the. The cable 34 is prevented from being loosened by the tension applying device 36. The tension applying device 36 is disposed inside the cover 26, and is supported by the bracket 54 attached to the ceiling 52 of the building with a frame member 38, and is supported by the frame member 38 so as to be rotatable about a horizontal axis. A support shaft 37 is inserted into a spring coil core 58 and a vertically long slot 38a formed in the frame member 38 thereof.
The roller 37 inserted vertically movably through the connecting member 39, a connecting member 39 connected to the roller so as to be relatively rotatable, and a portion that is wound around the winding core 58 and fed from the winding core 58 is connected to the connecting member 39. Band-shaped spring coil 4 to be connected
0. The elastic force of the spring coil 40 to wind around the winding core 58 applies a certain tension to the cable 34 wound around the roller 37 to prevent slack.

The transport of the fiber winding body 3 having the above configuration is performed by the control computer 35 in the following procedure.
First, the support arm 12 of the support member 11 is inserted into the inner peripheral hole of the fiber winding body 3 pulled out from the collet 7 at the doffing position by the receiving member 10, and then the receiving member 10 is displaced downward to support the support arm. The fiber winding body 3 is supported by the inner peripheral surface by 11, whereby the delivery of the fiber winding body 3 from the winding machine 2 to the transport device 1 is performed. When a completion signal of the delivery is sent to the computer 35 from, for example, a sensor for detecting the downward displacement of the receiving member 10,
The motor 30 is driven to rotate the ball screw 20, and the elevating member 17 starts to ascend. The lifting member 17
As the cam follower 56 is initially located in the linear portion 23b below the cam groove 23, the support member 11 rises without swinging, and after that the cam follower 56 reaches the spiral portion 23c of the cam groove 23 to be supported. When the cam follower 56 reaches the linear portion 23a above the cam groove 23, the support member 11 rises without swinging and stops after a while. Next, when a signal indicating the approach of the empty hanger conveyor 4 is sent from, for example, the proximity sensor for detection of the hanger conveyor 4 to the computer 35, the support member 11 re-rises to the delivery position without swinging. Support member 1 at the delivery position
The hanger portion 4a of the hanger conveyor 4 is inserted into an inner peripheral hole of the fiber winding body 3 supported by the fiber winding body 1. In addition,
The hanger portion 4a inserted into the inner peripheral hole of the fiber winding body 3 has a bifurcated shape, and is disposed at a position that does not vertically overlap with the support arm 12 that supports the fiber winding body 3 via the inner peripheral surface. . Next, by slightly lowering the support member 11, the fiber winding body 3 is supported by the hanger conveyor 4 via the inner peripheral surface. Next, when the hanger conveyor 4 moves, the fiber winding body 3 is pulled out from the support arm 12 and transported to the next step. Thereafter, the support member 11 descends and returns to the position where the fiber winding body 3 is received from the winder 2.

According to the above construction, the moment load acting on the support member 11 by supporting the fiber take-up body 3 via the support arm 12 is reduced by the guide blocks 17a, 17b.
Therefore, the supporting member 11 can have sufficient rigidity to move up and down while supporting the fiber winding body 3. Further, the support member 11
Since the main body is swingably supported by the elevating member 17 via the three bearings 15 and 16, the main body is swingably supported by the ceiling and the floor of the building. It is possible to swing stably without requiring a long time for centering.

Further, since the elevating movement of the elevating member 17 is converted into the oscillating movement of the support member 11 by the cam mechanism, a driving mechanism for oscillating the main body as in the prior art is unnecessary, and the apparatus can be downsized. Manufacturing costs can be reduced.

At the glass fiber spinning site, since the atmosphere contains a binder that adheres to the yarn fluff and the fibers at high temperature and high humidity, the supporting portion for supporting the supporting member 11 in a vertically movable and swingable manner is covered with the cover 26. By doing so, the rust-proof, dust-proof, and waterproof performance of the supporting portion is improved, and
Operating rate has been improved. In this case, since the ascending and descending motion and the swinging motion of the support member 11 are converted into the swinging motion of the cover 26, the cover 26 is swung by following the motion of the support member 11 without swinging the main body. The supporting side of the fiber winding body 3 of the supporting member 11 is connected to the opening 26a on the side surface of the cover 26.
In addition to projecting outward from a cut 27a formed in the seal rubber 27 that covers the seal rubber 27, the support portion of the support member 11 is prevented from being exposed.

The load cell 13 and the control device 35
Since the cable 34 connecting the cable 34 and the cable 34 in the cover 26 is prevented from being loosened by the tension applying device 36, the cable 34 is not entangled with the thread and does not cause a malfunction. That is, in the related art, the cable connecting the load cell 13 and the control device 35 is spirally wound, so that the cable can be expanded and contracted and the slack is prevented as the load cell 13 moves up and down. However, in the case of a cable having a spirally wound structure, the length or the diameter of the cable expands and contracts as the load cell 13 moves up and down, and the length or diameter of the cable increases. The fluff is entangled and the elasticity is reduced, restricting the elevating and lowering of the support member and causing malfunction, but the above embodiment does not have such a problem.

The present invention is not limited to the above embodiment. For example, the ball screw 20 and the ball nut 21 are not essential, and a trapezoidal screw and a nut may be used. Also, a cam groove 23 formed in the guide plate 22
Is not limited to the above-described embodiment, and may be any shape according to the movement of the support member 11. The configuration is not particularly limited as long as it is a mechanism that converts the elevating movement of the elevating member into the swinging movement of the supporting member. Not done.
