2. Description of the Related Art Plastic boxes are generally used for harvesting tomatoes, apples and the like and transporting them to processing plants. This box has a rectangular shape with an open top,
The harvested items are stored inside and used repeatedly. That is, the grower puts the harvested product in a box, places it on a pallet, carries it to the factory, and after discharging the harvested product, it becomes an empty box and is placed on the pallet and returned to the grower. At the time of this return, an "empty box transfer device" (Japanese Patent Publication No.
6623). This device abuts the edges of the openings of two empty boxes with one empty box inside.
These three empty boxes are integrated by putting in one, and the transport space is made compact.

However, in the above-mentioned conventional apparatus, since three empty boxes are individually conveyed when they are integrated, three conveyors are required, and A stopper that requires control in order to stop the empty box corresponding to each conveyor was required. Furthermore, when integrating the empty boxes, the two outer empty boxes are rotated by 90 degrees, and the longest side of the empty box is positioned at a right angle to the traveling direction for transportation. Therefore, there is a drawback that the conveyors 15 and 16 have to be large.

In view of the current situation, as a result of earnest research, the inventor of the present application integrally rotates three empty boxes by horizontally rotating the empty box located at the center and rotating the empty boxes on both sides around the traveling direction as an axis. By doing so, it was discovered that the short side of the empty box can be held and conveyed at a right angle to the traveling direction, and the device can be downsized, and the present invention was completed.

That is, the present invention comprises an empty box receiving device composed of a conveyor, a rotating disk horizontally rotatably installed in the center, and empty box chutes provided below and on both sides of the rotating disk. An empty box rotating device, an empty box built-in chute that is connected to the empty box chute, is narrowed toward the downstream side, and joins at the most downstream part, and is connected to a rotating disk. It is composed of an empty box assembly device consisting of a central empty box chute installed above and an empty box transfer device for intermittently transferring empty boxes. An empty box triplet device, characterized in that the box is rotated about the traveling direction and the central empty box is housed in the space portions of the empty boxes on both sides with which it abuts.
