``Prior Art'' Components such as contacts used in connectors and contact pieces used in switches are constructed by cutting and bending long strip-shaped spring metal thin plates and connecting them in a chain. A chain component winding device (hereinafter simply referred to as a winding device) is used to wind up the chain component onto a take-up reel. A conventional winding device will be explained with reference to FIG. A chain part 1 is supported by rollers 2 and a delivery sprocket 3.
The material is transferred to the take-up reel side, passed through the rollers 4 and further through the part guide 5, and is wound onto the take-up reel 6 with an appropriate slack initially set. The delivery sprocket 3 is rotationally driven by the delivery motor 7. The component guide 5 is a rectangular cylindrical body whose both sides parallel to the plane of the paper are rotatably supported at points p and p', and a line connecting the points p and p' provides a center line of rotation perpendicular to the plane of the paper. The chain-shaped component 1 is guided within the component guide 5 along a straight line (referred to as a guide line) that is perpendicular to the center line of rotation and leads to the exit. The angle θ (referred to as the swing angle) that this guide line makes with the vertical direction is determined by the slack state created by the chain-shaped parts 1. This swing angle θ is detected by a swing angle detector 8, and its detection signal is given to a control circuit 9. The control circuit 9 compares the swing angle θ with a reference value, and controls the speed of the servo motor 10 that rotates the take-up reel 6 so that the difference from the reference value falls within a predetermined range. The chain part 1 is therefore always given a certain range of slack during operation of the winding device.
This slack ensures that even if there are fluctuations in the feed-out speed by the feed-out sprocket 3 or the winding speed by the take-up reel 6, each operation is performed without affecting the other, and the smooth operation of the entire device is maintained. It is necessary for

"Problem to be Solved by the Invention" Since the chain-like parts 1 are given the above-mentioned slack, they come into contact with the upper edge of the outlet at the exit part of the part guide 5, and at this time the own weight of the part guide 5 is applied. . Therefore, depending on the type of chain-like parts, there is a possibility that they may be deformed.

"Embodiment" An embodiment of the present invention will be described with reference to FIG. In this figure, parts corresponding to those in FIG. 2 are denoted by the same reference numerals, and redundant explanation will be omitted. The chain part 1 supported by a roller 2 and sent out by a delivery sprocket 3 is wound onto a take-up reel 6 via a roller 20 after an appropriate slack is initially set. A feed encoder 21 is provided near the feed sprocket 3, and the feed encoder 21 generates a pulse and applies it to a first counter 22 every time the feed sprocket 3 rotates by a predetermined angle. Measuring sprocket 2 facing roller 20
3 is provided. The measuring sprocket 23 engages with the chain part 1 and is rotated by the transfer of the chain part. A measurement encoder 24 is provided near the measurement sprocket 23, and the measurement encoder 24 generates a pulse and applies it to the second counter 25 each time the measurement sprocket 23 rotates by a predetermined angle. The first counter 22 is the feed encoder 21
Count the pulses given by
N 1 is applied to the subtractor 26. Also, the second counter 2
5 counts the pulses given by the measurement encoder 24 and supplies the counted signal N 2 to the subtracter 26 . The subtracter 26 subtracts the count signal N 2 from the input count signal N 1 and provides the difference signal N 1 -N 2 to the control circuit 9. The control circuit 9 receives the input difference signal.
The rotational speed of the servo motor 10 is controlled so that N 1 −N 2 becomes zero. In this way, the winding speed of the take-up reel 6 is controlled to match the feeding speed of the feeding sprocket 3, and the winding speed of the winding reel 6 is controlled to match the feeding speed of the feeding sprocket 3.
The chain part 1 between the rollers 20 and 20 maintains a slack substantially similar to the initially set slack during operation of the winding device.

``Effects of the Invention'' According to the present invention, the appropriate slack initially set in the chain-like part 1 between the feed-out sprocket 3 and the take-up reel 6 is always maintained during the operation of the take-up device, and the slack state is maintained. Since the component guide 5, which could potentially deform the chained components, is not used for detection, there is no risk of deforming the chained components unlike the conventional method.
