Pre-adjust the length and lock with thumb screws 15 and 9.

On the other hand, the height of the arm 17 is adjusted according to the height of the toro box W. This height adjustment is performed so that the H interval shown in FIG. 3 is provided.

The toro box W is guided by the guide plate 24 as shown in FIG. 5 or 6, and is automatically carried into the rotary table 23 by the slide roller 25.

In this state, the toro box W and the substrate 1 may be shifted as shown in FIG. Then, the substrate 1 is pulled up by the cylinder 16 as shown in FIG. 3, whereby the substrate 1 is rotated by the positioning rod 19 and the positioning member 18, and the substrate is expanded and contracted from 1 to 1 'as shown in FIG. The arm moves from 6 to 6 ', and the pad 7 is positioned at the square of the toro box W. Then, as shown in FIG. 3, the substrate 1 is lowered to the position 1 'by the cylinder 16, and the toro box W is pressed with a predetermined pressing force.

This pressing force acts as a force for compressing the square of the tor box W, that is, the side wall of the box, and the telescopic arm 6 presses the tor box with a kind of spring effect.

Next, the polishing roller 30 is pressed against the side surface of the trolley box W with the cylinder 29 shown in FIG. 6, the tape end is adhered to the side surface of the trolley box W, and the polishing roller 30 is rotated by the motor 38, and the tape surface is rotated. (The peeling treatment is applied to the non-adhesive surface to facilitate the unwinding of the tape roll), and then the rotation of the polishing roller 30 is stopped.

When the rotary table 23 is rotated, the substrate 1 rotates with the trowel box W interposed between the substrate 1 and the rotary table 23 at an interval H.

By this rotation, the tape is pulled out by the polishing roller 30 and the side of the toro box W (the joint between the box body and the lid).
Pasted in. At this time, a rotational force or a rollover force acts on the toro box W due to the pulling force of the tape.

By firmly fixing the toro box W in this manner, the tape can be applied with an appropriate tension and without twisting or sagging.

Then, when the turntable 23 (toro box W) makes one rotation, the turntable 23 automatically stops.

Next, by operating the cylinder 33 shown in FIG. 6 and rotating the cutter arm 31 in the direction of the arrow, the tape is rolled.
The cutter blade is further pulled out by 39 and stuck to the first stripping processing removal section, and at the same time, the cutter
39 is pushed out and cuts the tape.

Next, the substrate 1 is lifted up by the cylinder 16, and the tip of the positioning rod 19 is guided in contact with the positioning member 18, thereby positioning the substrate 1 and simultaneously releasing the pressing force of the toro box W to complete the packing. Unload W. Then, the next toro box W is carried onto the rotary table 23, the substrate 1 is pushed down by the cylinder 16, the toro box W is fixed, and the next toro box W is packed in the same manner.

The above-mentioned transfer of the toro box, positioning of the substrate 1, fixing of the toro box, removal of the peeling process, driving of the rotary table 23 and sticking of the tape, and bonding and cutting of the tape to the stripping process removing portion are all automatic. It is something to be done.

(Effects of the Invention) As described in detail above, according to the present invention, the telescopic arm is provided on the substrate to determine the pressing position of the work in advance, and the substrate is positioned by the positioning rod and the positioning member. The displacement of the substrate is corrected, and the work can be firmly fixed by the telescopic arm.

As a result, the tape can be attached by applying an appropriate tension to the tape, and the tape can be reliably packed without twisting or sagging.

Also, since the above-mentioned positioning of the substrate is performed by the operation of lifting the substrate by the cylinder, it coincides with the operation of carrying out the work (pulling up the substrate and releasing the pressing force) and fixing the work (pressing down the substrate). The positioning and the unloading and fixing of the work can be performed simultaneously by vertically moving the substrate by the cylinder, which has the effect of shortening the packing work time and greatly increasing the packing processing.

Then, since the cylinder is provided at the rotation center of the rotary table and the substrate is rotatably mounted on the rod, the substrate rotates with the rotary table coincident with the rotation center. Even if they are different, the substrate and the turntable can rotate in the same manner without exerting excessive force.

Furthermore, there is an effect that it is possible to cope with various works by adjusting the height of the telescopic arm and the arm.
