  Next, the operation of the present embodiment as described above will be described.

  FIG. 5 is a schematic diagram for explaining a process in which the pallet 30 is accommodated in the pallet transport carriage 10 of the first embodiment. The pallet 30 is, for example, a flat pallet having a length of 1100 mm, a width of 1100 mm, and a height of 100 mm to 150 mm. Here, the “length”, “width”, and “height” of the pallet are in accordance with JIS Z0106. In this specification, the vertical posture is the posture of the pallet when the “length” or “width” of the pallet is set up in the vertical direction.

  As shown in FIG. 5A, in a state where the front wall 12 of the pallet transport carriage 10 is opened by the turning operation and one side of the front wall 12 is in contact with the ground, the pallet 30 in the vertical posture is Then, it rides on the inner surface of the front wall 12 from the contact portion between the front wall 12 and the ground.

  On the inner surface of the front wall 12, the bottom surface of the pallet 30 in a vertical posture is brought into contact with the ride-on support roller 22. When the pallet 30 is moved on the inner surface of the front wall 12 toward the inside of the box 11, the ride-on support roller 22 rotates about the rotation axis as the pallet 30 moves. As a result, the friction between the bottom surface of the pallet 30 in the vertical posture and the inner surface of the front wall 12 is reduced, and the pallet 30 is smoothly moved along the inclination of the front wall 12.

  Then, as shown in FIG. 5B, the pallet 30 in the vertical posture rides on the inside of the box 11 from the opened front wall 12 side of the box 11.

  Inside the box 11, the bottom surface of the pallet 30 in a vertical posture is in contact with the horizontal movement support roller 21. When the pallet 30 is horizontally moved on the bottom plate 16 toward the back plate 13, the horizontal movement support roller 21 rotates around the rotation axis according to the horizontal movement of the pallet 30. As a result, the friction between the bottom surface of the pallet 30 and the top surface of the bottom plate 16 in a vertical posture is reduced, and the pallet 30 is smoothly moved horizontally to the back wall 13 side, as shown in FIG. It is accommodated between the side wall 14 on one side and the partition wall 24 adjacent to the side wall 14 and is brought into contact with the back wall 13 to stop the horizontal movement.

  As shown in FIG. 5 (d), a plurality of pallets 30 are also obtained by repeating the steps shown in FIGS. 5 (a) to 5 (c) for another pallet 30 in the vertical posture. Is smoothly accommodated inside the box 11. By arranging the pallets 30 one by one between the side wall 14 or the partition wall 24, a gap is secured between the adjacent pallets 30, and the adjacent pallets 30 are reliably prevented from being contaminated. .

The front wall 12 is locked by the fastener so as not to be opened. Then, for example, when a handle (not shown) provided on the side wall 14 on the other side is pushed or pulled, the four wheels of the wheel portion 17 rotate and the pallet transport carriage 10 is moved. . Since the front wall 12 is closed, the pallet 30 is prevented from falling from the front wall 12 side during movement of the pallet transport carriage 10.

  Note that the steps shown in FIGS. 5A to 5E are performed in the reverse order to that described above, so that the plurality of pallets 30 accommodated in the pallet transport carriage 10 are grounded one by one. It is lowered smoothly.

  According to the present embodiment as described above, the pallet 30 in the vertical posture is smoothly moved along the inclination of the front wall 12 in contact with the ground, so that the work of lifting the pallet 30 is unnecessary. There is a significant reduction in the work load on the operator as compared to the conventional stacking operation. Further, after the pallet 30 in the vertical posture is put into the box 11 from the open front wall 12 of the box 11, the horizontal movement is supported by the horizontal movement support roller 21, and the box 11 It is smoothly accommodated up to the back wall 13 side. Thereby, since the operation | work which moves the pallet 30 is easy, compared with the conventional stacking operation | work, a worker's workload is reduced significantly. Further, since each pallet 30 can be brought into contact with a separate horizontal movement support roller 21 inside the box body 11, when a pallet 30 is horizontally moved, the other pallets 30 are kept stationary. It is also possible.

  In addition, since the plurality of pallets 30 are accommodated in a vertical posture inside the box 11, it is possible to provide a gap between adjacent pallets 30, and an upper surface of a certain pallet 30 (pallet loading surface). Can be prevented from coming into contact with the lower surface of another pallet 30 adjacent to it (the contact surface of the pallet) and being contaminated. For example, by arranging the partition wall 24 between the adjacent pallets 30 inside the box 11, it is reliably avoided that the adjacent pallets 30 are contaminated with each other.

  In addition, after the partition wall 24 is omitted inside the box 11 and a plurality of pallets 30 in a vertical posture are accommodated in the box 11, a partition member such as a sponge is inserted between adjacent pallets 30. By being inserted, a gap may be secured between adjacent pallets 30.

  Next, with reference to FIG.6 and FIG.7, the cart for pallet conveyance of 2nd embodiment is demonstrated.

  6 and 7, the pallet transport carriage 10 has the bottom plate 16 omitted from the box 11, and is parallel to the front wall 12 passed between the pair of side walls 14, 15 on the lower side of the box 11. A pair of side walls 14 and 15 below the front wall 12 is provided with a roller support shaft 25 of a proper orientation and a horizontal movement support roller 26 rotatably supported by the roller support shaft 25. The front wall 12 is hinged to the beam 26 and is in contact with the ground by a turning operation, except that a beam 26 passed between the two is provided. Other configurations are the same as those of the embodiment shown in FIGS.
