Abstract
This invention provides a transfer system capable of efficiently transferring, by use of a bidirectional conveyor, a transfer target between different points. The transfer system include a control device that: executes, in an alternate manner, a first mode in which a transfer target on a conveyor mechanism of a bidirectional conveyor device is transferred in a first direction and a second mode in which a transfer target is transferred in a second direction reverse to the first direction; and continues the first mode according to a predetermined first period defining a duration of the first mode.
Claims5
A transfer system comprising:
- a bidirectional conveyor device including a conveyor mechanism capable of transferring a transfer target bidirectionally;
- and
- a control device,
- the control device being configured to control the bidirectional conveyor device to execute a first mode and a second mode alternately, the first mode being a transfer mode for transferring a transfer target on the conveyor mechanism in a first direction, the second mode being a transfer mode for transferring a transfer target on the conveyor mechanism in a second direction reverse to the first direction,
- the control device being further configured to continue the first mode according to a predetermined first period defining a duration of the first mode, wherein
- in a case where, during the first period, there is no more transfer target which is to be transferred in the first mode and which is waiting for being transferred and there is a transfer target which is to be transferred in the second mode and which is waiting for being transferred, the control device executes, even before the first period ends, the second mode after given transfer of a transfer target which is being transferred is completed.

A transfer system, comprising:
- a bidirectional conveyor device including a conveyor mechanism capable of transferring a transfer target bidirectionally;
- and
- a control device, the control device being configured to control the bidirectional conveyor device to execute a first mode and a second mode alternately, the first mode being a transfer mode for transferring a transfer target on the conveyor mechanism in a first direction, the second mode being a transfer mode for transferring a transfer target on the conveyor mechanism in a second direction reverse to the first direction, and
- the control device being further configured to continue the first mode according to a predetermined first period defining a duration of the first mode;
- a first device configured to deliver or receive a transfer target to or from the bidirectional conveyor device at a first position on the conveyor mechanism;
- and
- a second device configured to deliver or receive a transfer target to or from the bidirectional conveyor device at a second position on the conveyor mechanism, wherein:
- the control device controls the bidirectional conveyor device, the first device, and the second device so that (i) in the first mode, a transfer target which is to be transferred from the first device to the second device by use of the bidirectional conveyor device is transferred via the bidirectional conveyor device and (ii) in the second mode, a transfer target which is to be transferred from the second device to the first device by use of the bidirectional conveyor device is transferred via the bidirectional conveyor device;
- and
- in a case where, during the first period, there is no more transfer target which is to be transferred from the first device to the second device by use of the bidirectional conveyor device and there is a transfer target which is to be transferred from the second device to the first device by use of the bidirectional conveyor device, the control device executes, even before the first period ends, the second mode after the transfer target which is being transferred arrives at the second position.
