A technology that can prevent leakage of confidential workpiece information in a course of workpiece transfer is provided. A pallet transfer system includes a transfer device, a pallet storage, a work station, a machine tool, and a control device. The control device determines whether or not the workpiece is a confidential target based on information indicating whether or not the workpiece to be machined is a confidential target, the control device transfers the pallet to which the workpiece is attached by a first transfer method when determining that the workpiece is not the confidential target, and the control device transfers the pallet to which the workpiece is attached by a second transfer method different from the first transfer method when determining that the workpiece is the confidential target.

Pallet transfer system, pallet transfer method, and pallet transfer program

A technique appropriately controls transfer order of a pallet. A pallet transfer system includes a transfer device, a pallet storage, a work station, a machine tool, and a control device. The control device transfers a second pallet from the work station to the pallet storage when the machining of the workpiece attached to a first pallet is completed in a state where the first pallet is in the machine tool and the second pallet is in the work station, and the control device transfers the first pallet from the machine tool to the work station after completion of the transfer of the second pallet from the work station to the pallet storage, or in parallel with the transfer of the second pallet from the work station to the pallet storage.

A technique for detecting the completion of work of attaching a workpiece to a pallet is provided. A pallet transport system includes: a transport device for transporting a pallet to which a workpiece can be attached; a pallet housing unit for housing the pallet, a workstation in which a worker is to conduct work of attaching the workpiece to the pallet transported from the pallet housing unit; a machine tool for machining the workpiece attached to the pallet in the workstation; and a control device for controlling the transport device. The control device acquires an indicator indicating progress of the attachment work in the workstation, determines whether or not the attachment work has been completed based on the indicator, and when it is determined that the attachment work has been completed, transports the pallet located in the workstation to the pallet housing unit or the machine tool.
