Composed by. Note that the reference numeral 24a indicates a cam follower provided on the second operating lever 24. The operating end side of the second actuating lever 24 is formed in such a shape as to sandwich the rotating body 1 from both sides, as shown in FIG. A chuck claw 3 is supported by a shaft protruding so as to face left and right, and has a flat notch formed on the oppositely protruding shaft, and grips the part A by this notch.

This chuck pawl 30 is combined with a pin 32 (see FIG. 3), and by pushing up the pin 32 against the elasticity of a spring (not shown), the chuck pawl 30 rises above the notch, creating a so-called chuck. By opening the chuck. The opening/closing of the chuck pawl 30 is performed by the actuation of an elevating rod 31 operated by air pressure or hydraulic pressure, and the elevating rod 31 is connected to a second actuating lever to cooperate with the movement of the lever. It is fixed to do so. Therefore, when the operating end of the second actuating lever 24 is operated toward the rotating body 1, the elevating rod 31 rises, opening the pawl 30 upward via the pin 32, and moving the end of the component A (the rotating body). 1) so that it can be held in its mouth. When the component A is gripped by the chuck pawl 30, the second operating lever 24 is actuated multiple times, and the component A and the tape 15 are pushed into the rotating body recess 11.

On the outward operating side (left side in FIG. 1) of 4, there is a pressure contact member 33 with which the tape-wrapped upper surface of the component A comes into contact.
is placed in pressure contact with the pressure contact member 33, and at the same time, the gear 27 including the rotating shaft 29 is rotated by the motor _M3 via the transmission gears 25 and 26, and as a result, the tape is wound onto the component A. The pressing member 33 is made of plastic, rubber, or the like so that the part A held in its grip is always in contact with one side of the part during rotation. The means for relative positioning of the lifting rod 31 and the pin 32 connected to the chuck pawl 30 is not shown, but a stopper pin provided on the shaft of the gear 27 is moved by the pressure of air or the like from the second operating lever 24. This is done by abutting against a positioning pin that protrudes and retracts within the rotation locus of the stopper pin. This air conduction path 35 is the third
It is indicated by the dotted line in the figure. Although an example is shown in which the chuck device and the tape winding gear mechanism are provided on both sides of the operating lever 24, it is sufficient to provide them only on one side, and the invention is not limited to this example. The cutter operation, chuck pawl operation, rotation operation, and degree setting operation of the gear 27 are programmed by a timing switch 36 (trade name: Micromat) connected to the cam shaft of the cam plate 7.

Next, the operation of the present invention will be explained. The rotating body 1 is dividedly rotated in the counterclockwise direction in FIG. 1, and in this state, parts are sequentially mounted in the recessed portion of the rotating body 1 via the component supply pedestal 14 according to the divided rotation. In accordance with the divided rotation of the rotating body, part A moves toward the apex of the rotating body, and at the position where it begins to descend after reaching the apex, the tape fed out from above the rotating body presses the part A around the outer periphery of the rotating body. , and the part A is held and moved without falling from the recess 11. Then, the tape is pressed by presser foot 18.
After the tape 15 is brought into close contact with the outer periphery of the rotating body 1, the tape 15 is cut into parts by a cutter 19, and reaches the tape winding mechanism 21. When the tape winding mechanism 21 is reached, the second actuating lever 24, which is equipped with a chuck device and a gear mechanism that rotates the chuck pawl, holds the part A and carries it out from the rotating body 1 together with the tape 15, and presses it. It is brought into pressure contact with the member 33. At this time, the fifth
As shown in Figures A and B, one end of the tape is brought into close contact with Part A at the same time as Part A is pressed, and then the motor _M3 is rotated to rotate the chuck (in the direction of the arrow) as shown in Figure 5B. Tape 15 is part A
wrap tightly around. As soon as the winding is finished, the second
The operating lever enters the action of holding part A, which is moving in parts, and part A, which has been wrapped with tape, hits the outer periphery of the rotating body immediately after the chuck is released and the chuck is opened, and as a result, it comes off the chuck and falls. and is guided to a parts chute (not shown). Thereafter, the above operations are repeated in sequence.

As described above, according to the present invention, it is possible to automate all the tape winding of electric parts such as magnetic cores onto rod-shaped members, etc., and furthermore, the means for transporting the parts and the tape winding means are connected to the rotating body and its surroundings. Since the winding of the tape can be completed in one rotation of the rotating body, mass productivity is significantly improved, and the apparatus itself can be made smaller.
