FIG. 3b is a side view as seen from the direction A in FIG. As shown in FIG. 3a, the tape chuck tip 333 is bent in an L-shape.

Next, the operation of the above device will be described with reference to FIGS.

First, with the longitudinal direction of the power cord 999 and the rotary gear 131 perpendicular to each other, the entire apparatus is moved by the gantry vertical cylinder 111 (shown in FIG. 1).
Rises to the center position of the rotating gear 131. The power cord is always held by another mechanism. This state is shown in FIG.

At this time, the tape contact cylinder 132
It retreats by the air supplied from the piping cylinder 170. This tape contact cylinder 132 inserts a coil spring 601 inside a cylindrical main body as shown in FIG.
A cap 602 is provided on the upper part. The cap 602 has a step portion for receiving air supplied from the piping cylinder 170. When the air is supplied, it retracts against the urging force of the coil spring 601.

In the home position shown in FIG.
Since the adhesive surface of the tape is on the upper side, it is adhered to the tape holding portion 135.

Next, from the state shown in FIG.
4 (shown in FIG. 1), the tape leading end gripping part moves in the z direction (back side), and the tape chuck 141 comes to a position where the tape can be clamped.

Next, as shown in FIG.
Is closed, the tape is gripped, and while holding the state, the tape tip gripping portion is lowered by the y-direction cylinder 143 (shown in FIG. 1) as shown in FIG. 6, and thereafter, as shown in FIG. Go in the direction and power cord 99
The chuck opens at the position after passing through the position 9, and the state shown in FIG. 8 is obtained. The reason for lowering in the y direction is that the tape
However, this does not cause a collision with the power cord when moving in the next x direction. The moving distance of the x-direction cylinder 142 and the y-direction cylinder 143 can be arbitrarily set according to the thickness and shape of the power cord and the like.

In FIG. 8, since the adhesive surface of the tape is on the upper side, it is adhered to the upper end of the tape chuck 141. Next, when the piping cylinder 170 is retracted, the tape contact cylinder 132 is raised, and the tape is pressed against the power supply cord 999 to be in the state shown in FIG. Thereafter, the tape leading end gripping part 140 separates from the tape and returns to the home position, that is, a position where the tape does not interfere during rotation.

However, as shown in FIG. 9, the leading end of the tape cannot be completely held down by the tape contact cylinder and is unstable. Then, in order to firmly adhere the leading end of the tape to the power supply cord 999, the tape is rotated counterclockwise until the leading end of the tape comes into close contact with the power supply cord 999 pressed by the tape contact cylinder 132. The amount of rotation differs depending on the close distance between the tip of the tape and the object. This is shown in FIG.

Next, the rotation method will be described.

The rotating unit 130 includes a servo motor 15 as a driving source.
2 allows rotation in both directions. The gear 150a is rotated by a pulley 153 and a belt 154 connected to a rotation shaft of the servo motor 152. As a result, the gears 150b and 150c also rotate, and finally the power is transmitted to the rotating gear 131. Here, the two gears 150b and 150c are provided in order to eliminate a step due to the power cord insertion opening of the rotary gear 131.

After the rotary gear 131 is rotated counterclockwise to a position where the leading end of the tape is brought into close contact with the power supply cord 999, the power supply cord 999 is rotated several times clockwise while being kept pressed by the tape contact cylinder 132. 11
And stop with the tape contact cylinder 132 positioned below.

The tape tension during taping will be described with reference to FIG. The tape reel 134 and the tape 133 are connected by a ball plunger 666, and the tape can be easily replaced. Further, the tension of the tape can be adjusted by the degree of tightening of the ball plunger 666.

Next, the tape cutting section 160 will be described. The tape after taping is located at a position connecting the power cord 999 and the tape roller 136. The adhesive side of the tape is on top. When the tape cutting cylinder 161 is raised, the tape holding plate 164 presses the tape, and the tape holding unit 135
To the state shown in FIG. Since the adhesive of the tape is on the upper surface, the tape reaches the tape holding unit 135. FIG. 17 is an enlarged view of the tape holding unit 135. The tape adheres to the lower surface of the tape holding unit 135 due to the adhesive force of the tape. Even after the tape pressing plate 164 presses the tape holding unit 135, the tape cutting cylinder 161 moves up. Then, the tape holding plate 1 is compressed by the compression spring 162.
64 retracts, blade 163 advances and cuts the tape. Thereafter, the tape cutting cylinder 161 moves backward.

After the cutting, the leading end on the tape side is
35, but the tape end on the power cord side is in an unstable state as shown in FIG. Therefore, the power cord 9
While the tape 99 is kept pressed by the tape contact cylinder 132, the tape is rotated one turn clockwise to bring the tape end into close contact with the power cord. Thereby, it is hard to peel off with tension, and it is possible to perform taping excellent in aesthetic appearance.

Finally, the gantry vertical cylinder 111 (shown in FIG. 1) is lowered, the power cord is released from the automatic winding device, and the next power cord is prepared.

According to this embodiment, after the tape is brought into close contact with the power cord, the tape contact cylinder 1
Since the tape 32 is rotated while being pressed and then rotated in the opposite direction, the tape can be prevented from being wrinkled when the tape is wound around the tape.

Further, since the tape contact cylinder is rotated while being pressed in the same direction as the tape winding direction even after cutting, the end of the tape can be securely adhered to the power cord. It is also possible to provide a power cord that does not easily peel off the tape.

[0036]

According to the present invention, after the tape is brought into close contact with the object such as the power cord, the mechanism for pressing the object and the tape toward the tip end of the tape not adhered to the object is rotated. Then, since the tape is wound by rotating the tape in the opposite direction, wrinkling of the tape that occurs when the tape is wound around the tape can be prevented.

Further, after cutting, the tape rotates while pressing the object and the tape in the same direction as the tape winding direction. With this configuration, the power supply cord or the like as an object can be securely adhered to the end of the tape, and a power cord or the like that does not easily peel off the tape even when the power cord or the like as an object is used is provided. be able to.
