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.

The present invention relates to a removal system and a method for removing parts processed in a processing system (200). The removal system is designed for engagement with a transportation unit (110) which is used for intermediate storage and/or transportation of a workpiece processed with the processing system (200), the processed workpiece comprising the parts to be removed. The removal system comprises a bridge movement system (120) which extends with its central longitudinal axis transversely to the longitudinal axis of the transportation unit (110) and can be moved axially in the longitudinal axis of the transportation unit (110). In addition, the removal system comprises a first parts conveyor system, which is arranged on the bridge movement system (120) and extends substantially parallel to the central longitudinal axis of the bridge movement system. Finally, the removal system comprises control unit which communicates with the transportation unit, the bridge movement system and the first parts conveyor system and provides control commands for the transportation unit, the bridge movement system and the parts conveyor system.

A loading device for a plunge-cut grinding machine for centerless external cylindrical grinding includes a receiving frame, a support body, and a displacement actuator. The receiving frame is open in a gravitational direction and is for receiving a blank workpiece to be machined. The support body forms a support base for the blank workpiece. The displacement actuator is for axially displacing the receiving frame relative to the support body and into a grinding gap of the plunge-cut grinding machine. The receiving frame includes a conveying stop on an axially facing end face. The conveying stop is for axially expelling a final workpiece arranged in the grinding gap.
