The present invention relates to a sheet roll transport vehicle suitable for standing up on a pallet or the like prepared at a required position.

[0002]

2. Description of the Related Art In general, a pallet is used when a plurality of sheet rolls are collectively supplied from a storage location to a sheet unwinding device, or are transported collectively from a sheet winding device to a shipping location. At that time, in order to prevent the sheet roll from rolling off the pallet, the sheet roll 1 is placed upright on the pallet 2 as shown in FIG. Then, the pallet 2 is transported to a target place by a forklift or the like. In addition, the sheet unwinding device or the sheet roll supporting portion of the winding device includes, for example, a pair of support arms 3 as shown in FIG.
And the chuck 4 is provided so as to face the tip of the support arm 3, and the sheet roll 1 is horizontally supported by engaging the chuck 4 with both ends of the core 5. Then, the sheet roll 1 standing on the pallet 2 in FIG. 5 is supplied to the sheet roll supporting portion 6 of the sheet unwinding device in FIG.
When supplying the sheet roll 1 to the pallet 2 of
For example, as shown in FIG. 7, a transport vehicle 9 having a loading platform 7 on which a sheet roll 1 is placed in a horizontal position and mounted on a carriage 8 is used.

[0003] A sheet roll 1 is transferred from a pallet 2 shown in FIG. 5 to a sheet roll support section 6 of a sheet unwinder shown in FIG.
In order to supply the sheet, the upright sheet roll is turned down, and FIG.
It is necessary to put on the carrier 7 of the carrier 9 as shown in FIG. In order to place the sheet roll 1 upright on the pallet 2 as described above from the sheet roll supporting portion 6 of the sheet winding device, the sheet roll 1 is horizontally moved from the sheet roll supporting portion 6 of the sheet winding device onto the transport vehicle 9 in FIG. It is necessary to raise the sheet roll 1 received in the posture and put it on the pallet 2 in FIG. And conventionally, when a sheet roll is transferred between the pallet and the sheet roll support section as described above,
Alternatively, the sheet roll is tilted or raised using a tipping device installed at a predetermined position.

[0004]

However, the work of raising and lowering the sheet roll by hand is a heavy labor for the operator, and involves a danger with a heavy sheet roll. In addition, a strong worker is required to knock down and raise the sheet roll without damaging it. Further, since the work of lowering the pallet and mounting it on the carrier is performed manually, it takes time to transfer the sheet roll.

[0005] Further, when the sheet roll is to be fallen down by using the overturning device installed at a predetermined position, it is necessary to transport the pallet on which the sheet roll is placed from the storage location to the vicinity of the overturning device. Then, the sheet roll must be transferred from the overturning device to the carrier. Also, when the sheet roll is raised by using the overturning device installed at a predetermined position, the sheet roll that has been erected by being transferred from the carrier to the overturning device is replaced by a pallet or the like prepared near the overturning device, and then the pallet, etc. Must be transported to storage. Therefore, when the sheet roll is toppled or raised using the conventional overturning device installed at a predetermined position, the sheet roll can be directly conveyed between the storage location and the sheet unwinding device or the winding device. It takes time and effort.

Accordingly, the present invention saves labor in transferring sheet rolls between a table or a floor on which a sheet roll in an upright position is placed and a sheet roll supporting portion of a sheet unwinding device or a winding device, and Work time can be shortened,
It is an object of the present invention to obtain a versatile sheet roll transport vehicle having a relatively simple structure.
