Abstract

A lifting and lowering movement control system for controlling an automatic conveyance vehicle configured to move with an article loaded thereon and a lifting and lowering device configured to move up and down in a state in which the automatic conveyance vehicle is on board, the system includes a lifting and lowering relevant information acquisition section configured to acquire lifting and lowering relevant information relating to the lifting and lowering device scheduled to be boarded by the automatic conveyance vehicle, and a movement control section configured to set a movement path to the lifting and lowering device scheduled to be boarded based on the lifting and lowering relevant information.

First claim

The invention claimed is:

1. A lifting and lowering movement control system for controlling an automatic conveyance vehicle configured to move with an article loaded thereon and a lifting and lowering device configured to move up and down in a state in which the automatic conveyance vehicle is on board, the system comprising:
a lifting and lowering relevant information acquisition section configured to acquire lifting and lowering relevant information relating to the lifting and lowering device scheduled to be boarded by the automatic conveyance vehicle; and
a movement control section configured to set a movement path to the lifting and lowering device scheduled to be boarded based on the lifting and lowering relevant information.

2. The lifting and lowering movement control system according to claim 1 ,
wherein the movement control section is configured to cause the automatic conveyance vehicle to move along the set movement path.

3. The lifting and lowering movement control system according to claim 2 ,
wherein the lifting and lowering relevant information acquisition section is configured to acquire, as the lifting and lowering relevant information, information of an arrival time at which the lifting and lowering device scheduled to be boarded is scheduled to arrive, and
the movement control section is configured to set a moving speed of the automatic conveyance vehicle based on a moving distance in the movement path and a time until the arrival time, and cause the automatic conveyance vehicle to move along the movement path at the moving speed.

4. A lifting and lowering movement control system for controlling an automatic conveyance vehicle configured to move with an article loaded thereon and a lifting and lowering device configured to move up and down in a state in which the automatic conveyance vehicle is on board, the system comprising:
a conveyance relevant information acquisition section configured to acquire conveyance relevant information relating to at least one of the automatic conveyance vehicle and the loaded article; and
a lifting and lowering control section configured to control the lifting and lowering device scheduled to be boarded by the automatic conveyance vehicle based on the conveyance relevant information.

5. The lifting and lowering movement control system according to claim 4 ,
wherein the conveyance relevant information acquisition section is configured to acquire, as the conveyance relevant information, information relating to a weight of the automatic conveyance vehicle including the loaded article, and
the lifting and lowering control section is configured to control the lifting and lowering device based on the weight of the automatic conveyance vehicle.

6. The lifting and lowering movement control system according to claim 5 , further comprising:
a notification section configured to perform a notification of an excess with respect to a limited weight of the lifting and lowering device,
wherein the lifting and lowering control section is configured to calculate an allowable weight obtained by subtracting the weight of the automatic conveyance vehicle from the limited weight of the lifting and lowering device, determine whether boarding of other objects excluding the automatic conveyance vehicle scheduled to board is possible based on the allowable weight, and cause the notification section to perform the notification of the excess in a case where it is determined that the boarding is not possible.

7. A lifting and lowering movement control method for controlling an automatic conveyance vehicle configured to move with an article loaded thereon and a lifting and lowering device configured to move up and down in a state in which the automatic conveyance vehicle is on board, the method comprising:
(a) a step of acquiring lifting and lowering relevant information relating to the lifting and lowering device scheduled to be boarded by the automatic conveyance vehicle; and
(b) a step of setting a movement path to the lifting and lowering device scheduled to be boarded based on the lifting and lowering relevant information.

8. A lifting and lowering movement control method for controlling an automatic conveyance vehicle configured to move with an article loaded thereon and a lifting and lowering device configured to move up and down in a state in which the automatic conveyance vehicle is on board, the method comprising:
(a) a step of acquiring conveyance relevant information relating to at least one of the automatic conveyance vehicle and the loaded article; and
(b) a step of controlling the lifting and lowering device scheduled to be boarded by the automatic conveyance vehicle based on the conveyance relevant information.
