Abstract

A corrugating roll unit conveyance apparatus includes a mounting base having a first accommodation part for accommodating a corrugating roll unit to be removed and a second accommodation part for accommodating a corrugating roll unit to be installed; and a movement device for moving the mounting base to a first replacement position at which the first accommodation part faces the existing corrugating roll unit, a second replacement position at which the second accommodation part faces a space from which the existing corrugating roll unit has been removed, and a retracted position separated from the first replacement position and the second replacement position.

First claim

The invention claimed is:

1. A corrugating roll unit conveyance apparatus comprising:
a mounting base having a first accommodation part for accommodating a corrugating roll unit to be removed and a second accommodation part for accommodating a corrugating roll unit to be mounted; and
a movement device for moving the mounting base to a first replacement position where the first accommodation part faces an existing corrugating roll unit, a second replacement position where the second accommodation part faces a space where the existing corrugating roll unit has been removed, and a retracted position separated from the first replacement position and the second replacement position,
wherein the first replacement position and the second replacement position are arranged side by side in a second horizontal direction orthogonal to a first horizontal direction which is a mounting direction and a removal direction of the corrugating roll unit, and
the movement device is adapted to move the mounting base in a sequential manner to a vertical position of the first replacement position along a vertical direction, to the first replacement position along the second horizontal direction, to the second replacement position along the second horizontal direction, and to the retracted position.

2. The corrugating roll unit conveyance apparatus according to claim 1 , wherein the movement device includes
a first traveling device which allows the mounting base to travel along the first horizontal direction,
a second traveling device which allows the mounting base to travel along the second horizontal direction, and
a switching device which switches the first traveling device and the second traveling device so as to be selectively used.

3. The corrugating roll unit conveyance apparatus according to claim 2 , wherein the switching device is a lifting device for lifting and lowering second traveling wheels of the second traveling device.

4. The corrugating roll unit conveyance apparatus according to claim 1 , wherein the movement device includes
a first movement device for moving the mounting base in the vertical direction, and
a second movement device for moving the mounting base along the second horizontal direction.

5. The corrugating roll unit conveyance apparatus according to claim 1 , wherein the mounting base is provided with a guide member for moving the corrugating roll unit along the removal direction and the mounting direction in the first accommodation part and the second accommodation part.

6. An apparatus for replacing a corrugating roll unit comprising:
the corrugating roll unit conveyance apparatus according to claim 1 ; and
a unit replacement mechanism for removing and mounting the corrugating roll unit between a single facer and the corrugating roll unit conveyance apparatus.

7. An apparatus for manufacturing a cardboard sheet, comprising:
the apparatus for replacing the corrugating roll unit according to claim 6 ; and
the single facer,
wherein the single facer includes
upper and lower corrugating rolls for nipping medium paper to perform corrugating on the medium paper,
an endless pressurizing belt which is wound around a plurality of support rolls and configured to pressurize and join the corrugated medium paper and a liner along with one of the upper and lower corrugating rolls, and
a belt support mechanism for preventing lowering of the endless pressurizing belt at the time of replacement of the upper and lower corrugating rolls, and

the endless pressurizing belt is disposed above the upper and lower corrugating rolls.

8. The apparatus according to claim 7 , wherein the belt support mechanism includes a support member for supporting the endless pressurizing belt between the plurality of support rolls.

9. The apparatus according to claim 8 , wherein the belt support mechanism includes a support member moving device for moving the support member to a retracted position where the support member is separated from the endless pressurizing belt by a predetermined distance and a support position where the support member supports the endless pressurizing belt.

10. The apparatus according to claim 9 , wherein the support member is a support rod for supporting the endless pressurizing belt between the plurality of support rolls from below in the vertical direction, and the support member moving device is capable of moving the support rod.

11. The apparatus according to claim 9 , wherein the support member is a suction member for suctioning the endless pressurizing belt between the plurality of support rolls from above in the vertical direction, and the support member moving device is capable of lifting and lowering the suction member.

12. The apparatus according to claim 7 , wherein the belt support mechanism is an adjustment device for adjusting a distance between the plurality of support rolls.

13. An apparatus for replacing a corrugating roll unit comprising:
the corrugating roll unit conveyance apparatus according to claim 3 ;
a stopper for blocking a movement of the mounting base when the mounting base is moved along the mounting direction of the corrugating roll unit by the first traveling device; and
a unit replacement mechanism for removing and mounting the corrugating roll unit between a single facer and the corrugating roll unit conveyance apparatus.

14. The apparatus for replacing the corrugating roll unit according to claim 13 , further comprising:
a minute movement mechanism for moving the mounting base in a direction opposite to the mounting direction of the corrugating roll unit by a minute distance set in advance, from a contact position with the stopper.

15. The apparatus for replacing the corrugating roll unit according to claim 14 , wherein the lifting device is capable of lifting and lowering the second traveling wheels, and the minute movement mechanism has first inclined surfaces having a convex shape and formed on one of each of the second traveling wheels and a floor surface, and second inclined surfaces having a concave shape and formed on the other of each of the second traveling wheels and the floor surface.

16. A method of replacing a corrugating roll unit comprising:
mounting a corrugating roll unit on a second accommodation part of a mounting base with a first accommodation part of the mounting base empty;
moving the mounting base to a vertical position of a first replacement position where the first accommodation part faces an existing corrugating roll unit along a vertical direction;
moving the existing corrugating roll unit to the first accommodation part at the first replacement position;
moving the mounting base to the first replacement position along a second horizontal direction orthogonal to a first horizontal direction which is a mounting direction and a removal direction of the corrugating roll unit;
moving the mounting base to a second replacement position where the second accommodation part faces a space where the existing corrugating roll unit has been removed, the first replacement position and the second replacement position being arranged side by side in the second horizontal direction;
moving the mounting base to the second replacement position along the second horizontal direction;
moving a corrugating roll unit of the second accommodation part to the space at the second replacement position; and
retracting the mounting base from the second replacement position.
