Abstract

A box moving device is disclosed. The box moving device changes the position of a box having four side surfaces. The box moving device is equipped with a conveyor and a movement control unit. The movement control unit drives the conveyor to cause the box to move from a first position to a second position. The conveyor can alternately switch between a first state, in which it is contracted along a moving direction of the box, and a second state, in which it is extended along the moving direction of the box. The movement control unit causes the box to move from the first position to the second position by driving the conveyor that is in a holding mode in which it holds at least one of the side surfaces of the box and simultaneously switching the conveyor from the first state to the second state.

First claim

1 . A box moving device for changing the position of a box having four side surfaces that are connected to each other in a loop, the box moving device comprising:
a conveyor that has at least a holding mode in which it holds at least one of the side surfaces of the box; and a movement control unit that drives the conveyor to cause the box to move along a moving direction from a first position to a second position, wherein the conveyor can alternately switch between a first state, in which it is contracted along the moving direction, and a second state, in which it is extended along the moving direction, and the movement control unit causes the box to move from the first position to the second position by driving the conveyor that is in the holding mode and simultaneously switching the conveyor from the first state to the second state.

2 . The box moving device according to claim 1 , wherein the movement control unit
switches the conveyor from the first state to the second state by causing an end portion of the conveyor to move from the first position to the second position and switches the conveyor from the second state to the first state by causing the end portion of the conveyor to move from the second position to the first position.

3 . The box moving device according to claim 1 , wherein
the conveyor further has a non-holding mode in which it does not hold the side surface, and the movement control unit causes the box to move from the first position to the second position, then changes the conveyor from the holding mode to the non-holding mode, and then switches the conveyor from the second state to the first state.

4 . The box moving device according to claim 1 , wherein the movement control unit causes the box to move from the first position to the second position by causing the box to move from above to below along the vertical direction in a state in which one of the four side surfaces of the box faces downward.

5 . The box moving device according to claim 4 , further comprising a flap guide, wherein
the box further has a flap that is a flat panel-shaped cover portion that extends from the side surface, and the flap guide guides the flap while the movement control unit is causing the box to move from the first position to the second position.

6 . The box moving device according to claim 4 , wherein in the holding mode the conveyor holds the two side surfaces that are along the moving direction.

7 . The box moving device according to claim 1 , wherein the conveyor is a telescopic conveyor whose holding surface that holds the side surface can extend and contract in the moving direction.

8 . The box moving device according to claim 7 , wherein the conveyor further comprises:
first and second drive pulleys; movable first and second guide pulleys; and an endless belt trained around the first and second drive pulleys and the first and second guide pulleys such that it is driven by the first and second drive pulleys; wherein the movement control unit causes the holding surface that holds the side surface to extend and contract in the moving direction by causing the first and second guide pulleys to move.
