As shown in FIGS. 1 to 4, the roll pallet according to the embodiment of the present invention has a pair of roll support bases 2 opposed to each other on a top surface of a pallet main body 1 into which a fork of a forklift truck can be inserted so as to be able to freely contact and separate. The stand 2 is provided with a protection device 3 for preventing the roll from sliding in the axial direction.

The pallet body 1 is provided with two cross beams 5 inside the outer frame 4, and has two gantry support beams 6 and one gantry fixing beam 7 between each cross beam 5 and the outer frame 4. The pallet stacking columns 8 are provided upright at the four corners of the outer frame 4. The gantry fixing beam 7 is arranged between the gantry supporting beams 6 and has a plurality of gantry fixing pin holes 9.

The support 8 is formed by inserting an upper support 11 into a lower support 10. The upper support 11 can be folded inward via a center bending pin 12 in the insertion portion, and when standing up, the pin 13 engages with the locking groove 14 and the upper support 11
(See FIG. 3).

The gantry 2 comprises a lower gantry 15 and an upper gantry 16. The lower gantry 15 has a pair of left and right bases 17 having an inverted U-shaped cross-section, and a hollow leg 18 is erected in an L-shape, and both bases 17 are joined by two front and rear cross beams 19. Since the gantry fixing plate 20 provided between the cross beams 19 is provided with at least one gantry fixing pin hole 21, the base 17 is slidably mounted on the gantry supporting beam 6 of the pallet body 1. I have. Each base 17 is provided with two rollers 22 so as to hold the gantry support beam 6 from below to prevent the gantry 2 from tipping over. The upper support 16 has a pair of left and right columns 24 joined at both ends of a roll support beam 23 in a gate shape, and a roll support U-shaped recess 26 provided with a rubber lining 25 at the center of the roll support beam 23. The support portion 24 is connected to the leg portion 18 of the lower base 15.
, And can be folded inward via a center bending pin 27 in the insertion portion. When the upper gantry 16 stands, the pins 28 engage with the locking grooves 29 to prevent the upper gantry 16 from falling down (see FIG. 1).

As shown in FIGS. 3 and 4, the protection device 3 is provided with a bearing portion 31 on a protection device support beam 30 erected between the support portions 24 of the upper base 16, and a bar-shaped handle 3 is provided at one end.
2 is rotatably supported by a bearing portion 31, and a male screw shaft 35 is rotatably screwed to a female screw block 34 provided at the other end of the handle shaft 33, and is protected at the tip of the male screw shaft 35. The holding member 37 of the plate 36 is connected.

The protection plate 36 is rectangular and has a holder 37 on the back surface, and a lining 38 made of foamed polyethylene or the like is provided on the front surface. The rotation of the handle shaft 33 allows the protection plate 36 to move in and out of the axial direction together with the male screw shaft 35. It has been.

The roll 39 is formed by winding a film-like object such as a plastic film or paper around a mandrel 40 as shown by a two-dot chain line in FIG. 1, and its size is not necessarily constant. Therefore, the height of the gantry 2, the number and pitch of the gantry fixing pin holes 9 and 21, the shape of the protection plate 36,
The dimensions, the amount of withdrawal and the like are systematically set in advance in accordance with the shape and dimensions of the rolls 39 to be loaded, so that various types of rolls 39 can be covered in a wide range with as few types of pallets as possible.

When the rolls 39 are stacked on the pallet having the above structure, first, the two gantry 2 are slid along the gantry support beam 6 in accordance with the length of the roll 39 to bring the two gantry 2 closer to each other. Alternatively, the distance between the two pedestals 2 is adjusted by separating them, and the pin holes 21 of the pedestal fixing plate 20 are
After that, the gantry fixing pins 41 are inserted into both the pin holes 21 and 9 (see FIG. 4), and the gantry 2 is fixed on the pallet body 1.

Next, both ends of the shaft 40 of the roll 39 are supported in the U-shaped concave portions 26 of the both bases 2. Subsequently, the handle 32 of the protection device 3 is rotated to cause the protection plate 36 to protrude from both gantry 2, and the protection plate 36 sandwiches both sides of the roll 39. Thereby, the protection plate 36 prevents the film-shaped object wound by the roll 39 from sliding in the direction of the center axis 40 in a bamboo shoot shape.

When the pallet is not used, the upper column 11 and the upper gantry 16 are folded. Thereby, the space required for transporting and storing the pallet itself can be saved.

[0016]

As described above, according to the present invention, a pair of gantry supporting the center axis of a roll is erected on a pallet body so as to be able to approach and separate from each other. When the rolls are stacked on a pallet, there is no need to attach two side plates for each roll with bolts and nuts as in the conventional case. Transport and storage of the rolls can be performed extremely easily and safely.

The height of the gantry, the adjustable range of the distance between the gantry, the size of the protection plate, the amount of withdrawal and the like are systematically set in advance in accordance with the size of the roll. Pallets can cover a wide range of rolls of various sizes, and work efficiency is dramatically improved.

A plurality of pallets can be stacked by pallet stacking columns provided at four corners of the pallet body.
The efficiency of transportation and storage can be improved. Furthermore, by making the pallet stacking columns foldable, the efficiency of transport and storage of the pallets themselves when not in use can be increased.
