Abstract

PURPOSE:To remove the interference between a coil mounting arm and a tape terminal processing part on the side of the end of winding so as to widen the automatic taping area by enabling the end finishing part to shift, in an automatic taping device which winds an insulating tape on the coil of a motor. CONSTITUTION:At the start of winding of a tape, a tape end finishing part 4 is located on the left side of a rotary heat 3, in short, is located on the opposite side to the arm of the supporting base of a coil. In the course of advancing taping, a motor rotates and pulls a chain 14, and shifts a tape end finishing part 4 to the right side of a rotary head 3, and shifts the rotary head 3 in that condition to the arm side, and completes the taping on one side of a coil. After that, it performs the fixation of a tape and the clamping and cutting of the tape, and then inverts the direction of the coil performs the taping on opposite side, and on the way, the tape end finishing part 4 is shifted to the left side of a rotary head 3, and the taping is continued while shifting the rotary head 3 to the arm side.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape winding start and end processing mechanism in a taping device for winding an insulating tape around a coil of an electric motor, for example.

[0002]

2. Description of the Related Art FIG. 3 is a general view of a taping device equipped with a conventional insulating tape end processing mechanism, FIG. 4 is a sectional view of a cutting and clamping mechanism, and FIG. 5 is a mounting view of the cutting and clamping mechanism. In the figure, 1 is a coil of an electric motor, 2a and 2b are arms of a support for the coil that supports the coil 1, 3 is a rotary head equipped with a ring that rotates when taping the insulating tape onto the coil 1, and 4 is a Cutting / clamping mechanism mount 4a, 4b are cutting blades of the cutting mechanism, 5a, 5b are claws of the clamp mechanism, and 6 are bolts for fixing the cutting / clamping mechanism mount 4 to the rotary head 3. A Z-axis slide unit 7 controls the vertical direction of the rotary head 3. Reference numerals 8 and 9 are for controlling the movement of the rotary head 3 in two horizontal axes. Reference numeral 8 is a Y-axis slide unit, 9 is an X-axis slide unit, and 9 is an X-axis slide unit. Each slide unit is configured to be movable up and down, front and back, and left and right by a motor and a feed screw.

Next, the operation will be described. When taping the insulating tape on the coil 1, the insulating tape is set on the rotary head 3, and one end thereof is held by the claws 5a and 5b of the clamp mechanism. In that state, the Z-axis slide unit 7, the Y-axis slide unit 8, and the X-axis slide unit 9 are operated to bring the rotary head 3 closer to a position where it does not interfere with the arm 2b. Next, the tape is adhesively fixed to the coil 1 (adhesive mechanism is not shown), and the claws 5a and 5b are attached.
Open and wind the tape around coil 1. The position control of the rotary head 3 is performed by the operation of the Z-axis slide unit 7, the Y-axis slide unit 8, and the X-axis slide unit 9 based on the data input to the control device according to the dimensions of the coil 1 at the same time as the rotation. Taping is performed so that the coil 1 is always positioned at the center of the rotary ring of the rotary head 3 while moving up and down, front and back, and left and right, and further while tilting the entire rotary head 3 by the operation of the motor. In this way, the tape is tapped to the arm 2a side, and the taping on one side is completed where it does not interfere with the arm 2a. Next, the tape is adhesively fixed, and the tape is gripped by the claws 5a and 5b for taping the opposite side, and then the tape is separated from the coil 1 by the cutting blades 4a and 4b. When the taping on one side of the coil 1 is completed in this way, the coil 1 is once removed from the arms 2a and 2b, the coil 1 is reversed in direction and set again on the arms 2a and 2b, and then taping on the opposite side from the arm 2b side is performed. Do the same.

[0004]

Since the conventional tape end processing mechanism is fixed to one surface of the rotary head 3 by a bolt as shown in FIG. 5, an arm to which a coil is attached is provided on the winding end side of the tape. There is a problem in that the tape end processing unit interferes with the rotary head before the tapeable range is narrowed.

The present invention has been made to solve the above problems, and an object of the present invention is to obtain a device for widening a taping area by making a terminal processing portion of a tape movable.

[0006]

A tape terminal processing mechanism according to the present invention is capable of moving a tape terminal processing portion from one side of a rotary head to the other side.

[0007]

In the tape end processing mechanism according to the present invention, the processing portion is movable instead of being fixed, so that the interference between the arm and the processing portion on the winding end side can be eliminated.
The taping area can be widened.

[0008]

EXAMPLES Example 1. An embodiment of the present invention will be described below. FIG. 1 is a front view and FIG. 2 is a plan view. In the figure, 3 and 4 are exactly the same as those of the conventional device.
Reference numeral 10 is a moving table to which the tape terminal processing unit 4 is fixed, 11 is a rail for guiding the moving table 10, 12 is a roller attached to the moving table 10 and running along the rail 11, 13 is a rail 1
1 is a base for fixing the rotary head 3 to the rotary head 3, and 14 is a moving base 1.
A chain for moving 0, 15 is a pin connecting the chain 14 and the moving base 10, and 16 is a sprocket directly connected to the motor 17, and the chain 14 is moved by the rotation of the motor 17.

Next, the operation will be described. The tape winding start process and the position control of the rotary head 3 during taping are the same as in the conventional example. At the beginning of winding, the tape end processing unit 4 is on the left side of the rotary head 3, that is, on the side opposite to the arm 2b, as shown in FIG. When the motor 17 is rotated in the direction of arrow 18 while taping is in progress, the chain 14
Is pulled, and the tape end processing unit 4 moves to the right side of the rotary head 3 along the rail 11. In this state, the rotary head 3 moves to the arm 2a side, and the taping on one side of the coil 1 is completed. Then, after fixing the tape, clamping the tape, and cutting the tape, the coil 1 is reversed in direction and tapped on the opposite side. This time, since the tape end processing unit 4 is on the right side of the rotary head 3, the arm 2
Taping is started from the a side, and the motor 17 is reversely rotated in the same way as before, and the tape end processing unit 4 is moved to the left side of the rotary head 3. In this way, the rotary head 3 advances to taping while moving to the arm 2b side.

Embodiment 2. Although the combination of the chain and the sprocket is used in the above embodiment, the same operation can be obtained by using the wires and belts.

[0011]

As described above, according to the present invention, since the tape end processing portion can be moved, it is possible to prevent the interference with the arm and thus to widen the taping area.
