[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plurality of wires, for example, a wire such as a steel wire as a material for manufacturing a spring, which can be wound into a coil unit having a predetermined shape and a predetermined amount, and which can be wound in multiple bundles. The present invention relates to a wire winding device capable of continuously forming a bundle of coils in a bundle.

[0002]

2. Description of the Related Art Among metal wires, spring wires, stainless wires, etc. are required to have a weight of 20 kg, 30 kg, and 30 kg.
They are often shipped in coil units with a small weight unit of Kg. As such conventional winding devices for winding a coil in units of a predetermined amount, there are a take-up system using an ascending pot and a take-up system using an IV type winder. As shown in FIGS. 8 and 9, in the former take-up method, a guide member 41 is mounted on an ascending pan 35 of a wire drawing machine, and the wire 7 which has been wound up while being wound around the ascending pan 35 is used.
Is wound up along the guide member 41 and stored directly on the shuttle 35. When the wire is wound up by a predetermined amount, the wire drawing machine is stopped, and the coil unit 8 as a product is lowered by the holding hook 42 called a stripper. (See FIGS. 8, 9A and 9B).

[0003] On the other hand, the latter trade-in method is shown in FIG. 10, in which a wire 7 is wound around a downward facing capstan 44, and the wire 7 wound several times is referred to as a stem which is installed below the capstan 44. (See FIG. 10 (A)). When a predetermined amount is wound on the winding frame 2, the wire drawing machine is stopped, and the winding frame 2 is taken out by a hoist or other hoist. After winding the wound wire 7 (see FIG. 10 (B)), lowering it, the winding frame 2 is installed again under the capstan 44, the wire drawing machine is started, and winding is repeated. .

In these conventional winding methods, in the case of winding, the wire drawing machine must be stopped and the product must be dropped down every time the length of the coil unit 8 arrives. , Workability and productivity were extremely poor. In addition, when the wire drawing machine is stopped and then restarted, the free coil diameter of the wire 7 (coil diameter in a state where no force is applied to the wire) tends to fluctuate, and the winding appearance of the coil unit 8 becomes uneven. In addition, there is a problem that correction work such as measuring and adjusting the coil diameter again is necessary.

Needless to say, the position is shifted by °.

Here, one of the wires 7 is
A length value per bundle is set (step S1), and the number of winding bundles to be wound by the winding frame 2 is set in the winding number counter (step S2). Next, the motor 16 is started to rotate the turntable 1 and the winding frame 2 to start winding (step S3), and the wire 7 fed from the wire feeding means at a predetermined speed is wound on the winding frame 2. . At the same time, the length counter of the wire 7 to be fed out is measured (step S).
4). The fed wire 7 is wound around the upper part of the stem winding part 22 of the winding frame 2, falls while rotating, and is deposited on the stem base part 21 as a coil of a bundle. When a predetermined amount of wire 7 is wound and reaches the specified length and the coil unit 8 is formed, the length counter is activated (step S5).
Automatically switches, and the rotary actuator 2
4 is driven, and at about the same time, the strip length counter is reset (step S6). As a result, since the support rod 9 is rotationally displaced by 8 °, the lowermost spacer 4A is unsupported as a result of the slit 18 being located at a position corresponding to the support rod 9, so that the lowermost spacer 4A during the winding operation is released. Only the spacer 4 </ b> A falls through the support bar, falls around the stem frame portion 22 of the winding frame 2, and rests on the coil unit 8.

At this time, since the spacer 4A is dropped while rotating synchronously with the turntable 1 and the winding frame 2, the coil unit 8 is smoothly and reliably prevented from being caught in the middle of the stem winding frame portion 22. You can put on. After the lowermost spacer 4A is dropped, winding is performed continuously. On the spacer supply means 3 side, spacers subsequent to the next spacer 4B are supported by support rods 9, where the bundle number counter Is incremented by one (step S7). Until the bundle number counter counts up the winding of the designated bundle number (step S8), the operations of steps S4 to S7 are performed in the same manner as described above, and the rotary actuator 2 is rotated.
4 is driven in reverse, so that the next stage spacer 4B
Falls, and thus the spacer 4 is attached to the winding frame 2.
It falls on the coil unit 8 as needed while rotating.
Then, the winding operation is stopped by winding the designated number of bundles , and the bundle number counter is reset (step S9).

In the conventional case in which the take-up frame 2 is taken in and out each time the coil unit 8 is wound up, it takes about 15 minutes for one take-in / out operation.
Assuming that six coil units 8 can be taken out by the continuous winding operation of five times, it is not necessary to take in and out five times, and 15 × 5 = 75.
The time can be reduced by one minute or more, that is, one hour or more.

In the example of FIG. 7A, the number of rotations of a wire drawing machine lift hook 35 is detected by a rotary encoder 36, and the value is detected by a programmable logic device.
The length of the wire 7 is calculated by calculation in a controller (hereinafter, referred to as PLC) 37. That is, a calculation of the length = the diameter of the ascending pot 35 × 3.14 × the number of rotations is performed, and when this value reaches the set length, a signal is sent from the PLC 37 to the electromagnetic switching valve 26 to insert the spacer 4. Supply. On the other hand, in the example of FIG. 7 (B), the wire rod 7 that travels by arranging the length measuring wheel 38 between the wire drawing machine lifting hook 35 and the winding device is wound around the wheel 38, and the length measuring wheel 38
The number of rotations is detected by the rotary encoder 36, the strip length is calculated in the same manner as in the above example (A), and the spacer 4 is supplied and supplied. In the example of FIG. 7C, the speed (length) of the wire 7 traveling between the wire drawing machine lifting hook 35 and the winding device is measured by the optical length measuring device 39 (a dedicated control unit). 40), and as in both (A) and (B) above,
When the set length is reached, the PLC 37 switches the electromagnetic switching valve 26
, And the spacer 4 is supplied and supplied. In this way, it is possible to reliably supply the spacers 4 for each coil unit 8 with good timing.

In the embodiment described above, a pneumatic circuit control type device is exemplified as the spacer supply means 3.
The present invention is not limited to such an embodiment, and the mechanism for reversibly inverting the support rod 9 is performed by supplying power to an electromagnetic solenoid through a slip ring, or by driving a motor, for example, a stepping motor. It is of course possible to substitute for the mechanical conversion method, and these modifications are also included in the scope of the present invention.
