Abstract

PURPOSE:To wind a metallic wire regularly by providing a winding drum concentrically disposed above an accumulating table turned within a horizontal plane at a space therebetween and rotating the winding drum to wind the metallic wire round the outer periphery of the drum, form same in a loop and be accumulated on the accumulating table. CONSTITUTION:A metallic wire 17 is guided by guide rollers 10, 11 to be wound once or twice round the outer periphery of a winding drum 5 and be formed in a loop, and then the wire is unwounded from the lower edge of the drum to be accumulated on an accumulating table 1 by its dead load. According to a speed change command of a sequencer, the accumulating table 1 repeates a stepped change, so that as the relative rotating speed of the accumulating table 1 increases, the metallic wire 17 unwound from the drum 5 gradually decreases in diameter of the loop, and is spirally arranged on the accumulating table 1 regularly. Subsequently, as the relative rotating speed of the table decreases, the metallic wire increases in diameter of the table decreases, the metallic wire increases in diameter of the loop and is accumulated on the spiral wire in an orderly way. By repetition of this operation, a bundle of coiled metallic wires having expected width and thickness can be formed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for winding a metal wire into a coil.

Generally, metal wire is often stored or transported by winding it onto a reel. However, winding onto a reel poses problems in the disposal of empty reels at the destination and the cost. Therefore, the metal wire is wound into a coil shape without a reel.
It has the disadvantage that it tends to become bulky due to irregular winding, and it is difficult to maintain a stable coil shape.

The present invention aims to provide a metal wire winding device that can neatly and tightly wind a metal wire into a coil shape with a desired width and thickness, and can eliminate the above-mentioned drawbacks. , winding drums are arranged concentrically at intervals above a material collection table that is arranged to rotate in a horizontal plane, and the winding drums are rotated to roll the metal wire around the outer periphery of the winding drums. A metal wire winding device that winds the metal wire into a loop shape by winding the wire into a loop shape, and then accumulates the metal wire on the collection table, wherein the rotational speed of the winding drum and the collection table are controlled. The metal wire is wound in a coil shape with a desired width and thickness on the material collection table by sequentially changing the relative speed with the rotational speed of the material collection table in a stepwise manner according to the number of rotations of the material collection table. That is.

An embodiment of the present invention will be described below with reference to the drawings.

In the external view of the device shown in Fig. 1, 1 is a disc-shaped material collection table fixed to a 20-rotation speed reducer output shaft B so as to rotate in a horizontal plane, and 4 is a variable speed motor that is its driving source. . 6 is above the material collecting table 1 and the material collecting table 1
A winding drum is arranged concentrically with
il 8, and is rotated by the drive of a variable speed motor 9. 1O111 is the handle hanging down from frame 6 (1
A guide roller 14 is rotatably supported on shafts 12 and 13, and an arm 16 is pivotally supported on a mounting shaft 15 hanging near the winding drum 5, and a guide roller 14 is rotatably supported on the tip of the arm 16. The pressure roller 14 is brought into pressure contact with the outer periphery of the winding drum 5 by urging the arm 16 with a spring (not shown). The gold Rfi 17 passed through a continuous heat treatment device (not shown) is guided by guide rollers 10 and 11 and wound around the outer periphery of the winding drum 6, thereby creating a loop-shaped curl. After that, it unravels from the lower edge of the winding drum 6 and accumulates on the collection table 1 due to its own weight. FIG. 2 1 shows a control system diagram of the metal wire winding device. In the figure, the same reference numerals as in FIG. 9, a sequencer whose operation is stepped by the on/off signal of the limit switch 19, and the speed detection signal of the detector and the output of the sequencer. It consists of a speed control board 21 for inputting signals, an operation panel η for pre-programming the operating order in the sequencer powder, and an inverter n for transmitting the speed control command signal of the speed control board 21 to the variable speed motor 4. Sequencer beauty is limit switch 1
9 is turned on and off, the third controller issues a speed switching command to the speed control board 21 according to a preprogrammed operation order.
In the figure, the horizontal axis represents the number of 10 rotations of the material collection table, and the vertical axis represents the relative ratio between the rotational speed of the winding drum 50 and the rotation speed of the material collection table 10, and the relationship is expressed in a diagram.In this case, Every time the material collection table 1 rotates twice, the relative ratio increases by 3%.
The material collection table 1 gradually becomes higher in steps, and when the relative ratio becomes 30% higher than the initial value after 7.2 rotations, it returns to the 70% high level after 3 rotations and 5% after 3 more rotations.
After three more rotations, it returns to the original level, and thereafter repeats the step-like change.As a result, the gold R wire I7 that has come undone from the winding drum 5 has a relative rotational speed of the material collection table 1. The loop diameter gradually decreases as the material rises, and the material is arranged on the collection table 1 in an orderly spiral shape.Next, as the relative rotational speed of the material collection table 1 decreases, the loop diameter increases accordingly and the material is collected on the material collection table 1 in an orderly manner. Therefore, by repeating this process, it is possible to form a coil-shaped Kon-ku line Higashi with the desired width and thickness on the wood collection table 1. In this case, when increasing the relative ratio of rotational speed, it was done every 2 rotations, whereas when decreasing it, it was done every 3 rotations, making the rate of change significantly. That is, the one-winding drum 5, which prevents the metal wires from crossing each other as the loop diameter gradually increases, pulls the metal wire 17 in accordance with the processing speed of a continuous heat treatment device (not shown). However, the rotational speed of the winding drum 5 is detected by the detector 18 and input to the speed control board 21. Therefore, the speed control board 21 receives the input winding drum 50.
The rotation speed of the material collection table 1 is controlled so that the relative ratio changes as illustrated in FIG. 3, with the rotation speed being expressed as %Q's. Note that various conditions such as the rate of change of the relative ratio and the number of changes can be adjusted in any manner by inputting the data in advance into the operation panel η depending on the diameter of the metal wire to be wound and the shape of the coil to be formed.

As described above, the metal wire winding device of the present invention allows metal wire to be wound neatly into a coil with a desired width and thickness without using a reel. Therefore, the bulk is reduced, which has the very advantageous effect of reducing transportation, storage, etc. costs.
