Abstract

A conveyance system including a conveying vehicle configured to convey a conveying object, a sensor configured to acquire the information relating to the conveying object, and a control device configured to control the conveying vehicle is designed to identify a contact position at which the conveying vehicle comes in contact with the conveying object when conveying the conveying object based on the information relating to the conveying object, and to control the conveying vehicle according to the contact position.

First claim

What is claimed is:

1. A conveyance system comprising a plurality of conveying vehicles configured to convey a conveying object and a sensor configured to acquire information relating to the conveying object, the conveyance system implementing:
identifying a contact position at which the plurality of conveying vehicles comes in contact with the conveying object when conveying the conveying object based on the information relating to the conveying object;
controlling the plurality of conveying vehicles according to the contact position; and
identifying a side face of the conveying object to be sandwiched by the plurality of conveying vehicles,
wherein the controlling the plurality of conveying vehicles according to the contact position includes controlling the plurality of conveying vehicles each according to the contact position on the side face.

2. The conveyance system according to claim 1 , wherein the information relating to the conveying object includes image information capturing the conveying object and height information of the conveying object.

3. The conveyance system according to claim 1 , wherein the controlling the plurality of conveying vehicles controls the conveying vehicle according to the contact position representing a center of a side face of the conveying object.

4. The conveyance system according to claim 2 , wherein the sensor is configured to measure the image information and distance information for each position of the conveying object, and wherein the controlling the plurality of conveying vehicles identifies the contact position based on the image information and the distance information.

5. A control device comprising:
a processor and a memory configured to store instructions, the processor executing the instructions to:
communicate with a plurality of conveying vehicles configured to convey a conveying object and a sensor configured to acquire information relating to the conveying object;
identify a contact position at which the plurality of conveying vehicles comes in contact with the conveying object when conveying the conveying object based on the information relating to the conveying object;
control the plurality of conveying vehicles according to the contact position; and
identify a side face of the conveying object to be sandwiched by the plurality of conveying vehicles,
wherein the controlling the plurality of conveying vehicles according to the contact position includes controlling the plurality of conveying vehicles each according to the contact position on the side face.

6. The control device according to claim 5 , wherein the information relating to the conveying object includes image information capturing the conveying object and height information of the conveying object.

7. The control device according to claim 5 , wherein the processor is configured to control the conveying vehicle according to the contact position representing a center of a side face of the conveying object.

8. The control device according to claim 6 , wherein the sensor is configured to measure the image information and distance information for each position of the conveying object, and wherein the processor is configured to identify the contact position based on the image information and the distance information.

9. A control method comprising:
communicating with a plurality of conveying vehicles configured to convey a conveying object and a sensor configured to acquire information relating to the conveying object;
identifying a contact position at which the plurality of conveying vehicles comes in contact with the conveying object when conveying the conveying object based on the information relating to the conveying object;
controlling the plurality of conveying vehicles according to the contact position; and
identifying a side face of the conveying object to be sandwiched by the plurality of conveying vehicles,
wherein the controlling the plurality of conveying vehicles according to the contact position includes controlling the plurality of conveying vehicles each according to the contact position on the side face.

10. The control method device according to claim 9 , wherein the information relating to the conveying object includes image information capturing the conveying object and height information of the conveying object.

11. The control method according to claim 9 , comprising: controlling the conveying vehicle according to the contact position representing a center of a side face of the conveying object.

12. The control method according to claim 10 , wherein the sensor is configured to measure the image information and distance information for each position of the conveying object, and wherein the control method further comprises thus-identifying the contact position based on the image information and the distance information.
