When assembling a spring, in which the hooks at both ends of the tension coil spring are hooked onto a pair of hook receivers formed on the product, in order to reduce entanglement between the tension coil springs, the winding diameter portion of the spring should be tightly wound or the tension coil spring should be tightly wound. The hook part of the coil spring is wound over 360 degrees to eliminate the opening and the parts feeder is used to supply the parts. Since it is difficult to assemble a tension coil spring having a long length, the work of assembling the tension coil spring has heretofore been mainly carried out manually, and only some parts have been automated.

があつた。 For this reason, in the former case, even when the product assembly is automated, only the work of assembling the tension coil spring must be done manually by an operator, making it impossible to unmann the assembly line. In addition, the latter method is not compatible with hook receivers of different shapes and heights, and when installing a tension coil spring with a large spring constant or a tension coil spring with a large extension, the device becomes large and heavy. At the same time, there was the disadvantage that the structure became complicated.

The present invention solves the above-mentioned disadvantages of the prior art, thereby making it possible to determine the direction of the hook portions at both ends of a tension coil spring supplied from a spring supply device to a spring receiving block, and to hold the spring in that state. In addition, the present invention aims to be compatible with various tension coil springs having different spring winding diameters, wire diameters, and lengths, to be lightweight and compact, and to enable automation of the assembly of tension coil springs.

When the tension coil spring 4 is supplied, the tension coil spring 4 is temporarily positioned by the spring delivery part 5 provided at a predetermined position of the supply guide 2, and is supplied to the upper surface of the spring receiving block 6 located below. Air cylinder 1 after supplying spring
7, the spring receiving block 6 is moved to the left via the slide table 16.
The tension coil spring 4 is transferred and held in the V-shaped notch groove 7 that has moved from the upper surface of the spring receiving block 6 to the lower side of the spring transfer portion 5 (FIG. 3b). In this state, the orientation of the hook portion 4a of the tension coil spring 4 changes each time the spring is supplied and is not constant. Next, when the spring receiving block 6 is moved rightward by the air cylinder 17, the tension coil spring 4, whose winding diameter portion 4b is held by the V-shaped notch groove 7, moves to the inclined surface of the slope guide 8. Since the hook portion 4a is moved to the right with respect to the hook portion 4a, the hook portion 4a is moved to the right as shown in FIG.
After a part of the slope 8a comes into contact with the slope 8a,
It is rotated clockwise as shown by the arrow by the rotational moment received from. This rotation continues until the entire hook portion 4a comes into contact with the inclined surface 8a,
After that, it does not rotate, and the inclined surface 8a and the hook part 4a
A horizontal surface 8 that follows the inclined surface 8a by sliding between
b, where the hook portion 4a is placed on the horizontal surface 8.
The positioning of the hook portion 4a of the tension coil spring 4 is completed when the hook portion 4a of the tension coil spring 4 is rotated to the position where it contacts the spring 4b. When the movement of the spring receiving block 6 is stopped by the air cylinder 17, the tension coil spring 4
is held at a predetermined position by the tip of a presser plate spring 12 provided above the spring receiving block 6 (FIG. 3d).
