In this shipping operation, the worker manually attached an adhesive tape to the joint between the styrofoam box body and the lid. This sticking operation of the adhesive tape is a laborious operation, and the shipping capacity is extremely low. In view of this, the inventor has already proposed a tape sticking device for performing the above operation by a machine (Japanese Utility Model Application No. 62-155998).
issue).

(Problems to be Solved by the Invention) It is an object of the present invention to further improve the above-mentioned tape application device, automatically apply the tape, and improve the efficiency of shipping work.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a rotary table in which a force is applied upward by a spring to a work loading side and a rotatable stopper and a work unloading side. A rear stopper is provided so as to be able to stand up and roll over in a direction perpendicular to the work transfer direction, and the distance between the front stopper and the rear stopper can be adjusted according to the size of the work. After the work has passed over the front stopper, the tip of the front stopper rises above the transfer surface and comes into contact with the side surface of the work after the work has passed over the front stopper. A slide roller is provided from the work carry-in side to the work carry-out side, and a guide plate is provided outside the slide roller.

(Operation) The present invention is configured as described above, and has the following operation. That is, the work carried into the rotary table depresses the front stopper against the elastic force of the spring,
The work moves on the roller while being guided by the guide plate, and stops when the front end of the work hits a rear stopper that is standing upright. At the same time, the work passes through the front stopper.
The distance between the front stopper and the rear stopper is adjusted according to the size of the work, and the position at the center of rotation of the front stopper is set to the front position after the work passes over the front stopper. Since the tip of the part stopper rises above the transport surface and is in a position where it contacts the side surface of the work, the tip of the front stopper contacts the rear side surface of the work. As a result, the work is restrained on both sides by the guide plates, the movement in the front-rear direction is stopped by the front stopper and the rear stopper, and the work is fixed at a predetermined position on the rotary table.

After the tape has been applied, the rear stopper can roll over and stand up in the direction perpendicular to the workpiece transfer direction, so even if the rear stopper abuts against the side of the work, the rear stopper can roll over. The work is carried out from the rotary table.
