Description

[Detailed Description of the Invention] The present invention relates to a wire material device used when forming a wire material-wound frame by winding a wire around a frame body while applying high tension.

Usually, as shown in FIGS. 1 and 2, this type of device includes a wire reel 2 around which a long wire 1 is wound, and a wire reel 2 that is provided at a distance from each other, and a wire that is fed out from the wire reel 2. A pair of tension rolls 3 that apply braking force to 1 to provide high tension.
, a traverser 4 that adjusts the moving height of the wire 1 sent from the tension roll 3, and a winding device 6 that places the frame body 5 and rotates it.
It is composed of.

By the way, in such a wire winding device, if the wire 1 of the wire reel 2 runs out or breaks while winding the wire 1, it is necessary to replace the wire reel 2 with a new one or connect the wire 1. However, in this case, in the case of a conventional device, the device had to be stopped to interrupt the winding operation, which was extremely inefficient.

The present invention solves the above conventional problems by providing the tension roll with an operating cylinder that narrows the distance between the tension rolls and providing a wire accumulator function. When the reel runs out of wire or the wire breaks, the distance between the tension rolls is narrowed and the wire stored in the tension rolls is continuously fed out, during which time the wire reel can be replaced. It is an object of the present invention to provide a wire material winding device which can proceed with wire winding work without stopping the device.

Hereinafter, the present invention will be explained in detail based on the drawings.

FIG. 3 shows the main part of an embodiment of the present invention, in which a wire 1 such as a long piano wire is wound around a wire reel 2 for a predetermined amount, and the wire 1 is pulled out from the wire reel 2. It is mainly composed of a pinch roll 16 that can be powered, a plurality of tension rolls 3 that apply high tension, and an operating cylinder 7 (accumulator) attached to the tension rolls 3. The wire reel 2 is rotatably supported on the bed of the device, and when the tip of the wire 1 is pulled outward, it rotates in response to this and the wire 1 is paid out in sequence.

The above-mentioned tension roll 3 has a groove formed on its outer periphery for the wire 1 to run, and a plurality of tension roll shafts 8 are freely connected to a pair of tension roll shafts 8 which are appropriately spaced apart from each other through a metal. It is installed so that it can be rotated. On the other hand, the working cylinder 7 has one end connected to one tension roll shaft 8 and the other end connected to the other tension roll shaft 8, and the expansion of the working cylinder 7 causes the pair of tension roll shafts 8 to be connected to each other. During the winding of the wire 1, the tension roll shafts 8 are pressed in a direction that separates each other, and therefore a plurality of the tension rolls 3 in the set are pressed in a direction that separates from each other, and this force causes the tension rolls to move away from each other. A braking force is applied to the wire 1 which is wound around the frame body 5, and a high tension is applied to the wire 1. Also, wire 1 of wire reel 2
If the tension rollers 3 are lost or broken, the actuating cylinder 7 retracts and the respective tension roll shafts 8 approach each other, so that the distance between the tension rolls 3 is narrowed.

Furthermore, the wire 1 paid out from the tension roll 3 is guided to an appropriate movement height by a traverser 4 as before, and wound around a frame body 5 such as a press frame or a pressure vessel rotated by a winding device 6. It is starting to be taken away.

In addition, in Fig. 3, 9 is a sensor roll,
It is attached to a lever 11 that rotates about a fixed shaft 10 as a fulcrum, so that it can rotate freely.
This lever 11 transmits the displacement of the sensor roll 9 due to tension fluctuations of the wire 1 to a tension sensor 12 such as a load cell, and the signal is transmitted to a controller 13, and this tension signal and a signal from a tension setting device 14 are are compared and calculated, and the signal is transmitted to the tension control brake 15 to control the tension of the wire 1.

Next, the operation of the present invention will be explained. When using the wire winding device of the present invention, first, the frame body 5 is placed on the winding device 6, and the wire 1 is pulled out from the wire reel 2 and sequentially applied to each tension roll 3 and sensor roll 9. It is wound and fixed to the frame body 5 via the traverser 4. Then, with the operating cylinder 7 extended, the winding device 6 is operated to wind the wire 1 around the frame body 5. Further, if the wire 1 of the wire reel 2 is lost or broken while winding the wire 1, the actuating cylinder 7 is retracted to narrow the distance between the tension rolls 3. Then wire 1
continues to be wound around the frame body 5,
One end of the wire reel 2 remains in its original position, and during this time the operator replaces the wire reel 2 with a new one and connects a new wire 1 to one end of the wire 1 or connects the broken wire 1. In this way, the operator can replace the wire reel 2 without stopping the apparatus.

In addition to the illustrated accumulator 7, it is also possible to use one in which the distance between the roll axes does not change, such as a rotary accumulator. Further, instead of the pinch roll 16, a wire material clamping device consisting of a clamp plate 18 and a cylinder 19 may be provided as shown in FIG. 4, or a brake roll equipped with a brake 20 as shown in FIG. 17 and the pinch roll 16 may be used in combination.

Furthermore, a part of the tension roll 3 may be braked and provided with a pinch roll.

As described above, according to the present invention, the distance between the tension rolls is widened to apply tension to the wire, while the distance between the tension rolls is narrowed to allow the wire to be pulled out from the wire reel while continuing to wind the wire. Since the wire reel is interrupted, the wire reel can be replaced without stopping the winding device, and therefore the workability of wire winding can be greatly improved.
