Description

DETAILED DESCRIPTION OF THE INVENTION This taping of a wire harness in electrical wiring of an automobile can be easily operated with one hand.

A wire harness is a bundle of many electric wires, but in the electrical wiring of a car, it is used for the ignition system.

Since lighting systems, optical power circuits, etc. have a large number of loads, the number of electric wires used is enormous, and the wiring needs to be wired according to the placement of various loads, resulting in many branches and their shapes. It becomes complicated. Therefore, when wiring, in order to prevent vibration, noise and friction while driving, and to simplify wiring,
It must be converged as a wire assembly in advance. Conventionally, such convergence work has been done by a worker manually winding the wire harness one at a time due to its complex shape, which requires a great deal of labor and time, and the quality varies widely. (The disadvantage was that the productivity of the wire harness was poor.

The present invention was made to improve these drawbacks.
To provide a tape winding machine that anyone can easily use by operating a switch with one hand, thereby greatly improving the productivity of wire harnesses.

Further, eight bull knife-shaped pressurizers 821 that engage with the contacts of the microswitch 22 attached to the base plate 3 are provided at the center of the outer periphery of the rotating drum 17 .

Further, on the outer periphery of the rotating drum 17, a tape attachment part 23 is provided on one side in the diametrical direction, and a balancer 40 is provided on the other side.

The tape attachment part 23 is formed by rotatably fitting the knob 2T into a tape holder 24 having a flange 25 on the outer periphery via a spring 2@.

That is, the knob 21 has an inner part connected to the shaft hole 2, as shown in Figure H3.
It has a configuration in which a tube 30 is provided at one end of a cylindrical main body 28 having a diameter of 9, and an annular *St is provided at the outer periphery of the other end. This cylindrical body 28
is inserted into the inner hole 32 of the tape holder 24, and a stop ring 33 is fitted into the protruding annular groove 31 to prevent removal. Further, in the shaft hole 29 of the knob 210, a pair of pin guides #134 facing each other in the axial direction are recessed in the axial direction.
A pin locking groove 35 is provided on the outer surface of the camera 30 so as to be orthogonal to the guide groove 34. On the other hand, a mounting bracket X is attached to the rotating drum 11.
31i is fixed with screws, and a long hole 31 is opened in the metal fitting 36.
A knob shaft 38 having a locking pin 311 protruding from its tip is fixed to the knob shaft 38 . Attach the knob 2T to this 7th axis 3B in the bottle guide groove 34Ka.
By fitting and inserting it and rotating it 90', the locking pin 39 engages with the bottle locking groove 3SK, and the knob 21 is detachably attached.

On the other hand, the balancer 40 is a weight for maintaining balance with respect to the tape attachment part 23, and is a weight for maintaining balance with respect to the tape attachment part 23.
A long hole 42 is opened in the mounting bracket 41 provided in the long hole 4.
Fix it with screws 2. Therefore, the balancer 40 and the tape attachment part 23 can be moved left and right within the range of the elongated holes 42 and 37 to maintain their balance.

Further, 43 is a failure switch for the motor 5 provided in the grip 1, and its wiring diagram is shown in FIG.

In addition, the main drive gear 8, the transmission gear B, the rotating drum 1γ,
Although the tape holder 24, knob 21, etc. are made of synthetic resin to reduce weight, they are not limited thereto.

Note that 44 is a motor cover, which is fixed to a cover attachment pin 45 attached to the base plate 3 with screws.

In the above configuration, first, as shown in FIG. 5, the winding tape T is mounted on the tape holder 24 and fixed to the horn shaft 38 via the knob 21. Since a spring 26 is interposed between the knob 2T and the tape holder 24, when the 7-pin 27 is locked by the locking pin 39 of the knob shaft 38, the tape T is pressed toward the mounting bracket 3B and stabilized. do.
