Abstract
A work transfer apparatus includes a holding unit (100) that rotates together with a rotation table (20) as a transferring mechanism intermittently driven to be fed, a lifting and lowering unit (200) for lowering the holding unit in order to transfer a workpiece held by the holding unit onto a processing table (30) as well as lifting the holding unit in order to transfer the workpiece held on the processing table onto the holding unit, and a fixing unit (300) that fixes the workpiece held on the holding unit and releases the workpiece when transferring the workpiece onto the processing table.
Claims9
A work transfer apparatus capable of transferring a workpiece intermittently carried in a predetermined carrying direction by a transferring mechanism onto a processing table arranged along the carrying direction, the work transfer apparatus comprising:
- a holding unit that is attached to the transferring mechanism and configured to hold the workpiece;
- a lifting and lowering unit that lowers the holding unit to transfer the workpiece held by the holding unit onto the processing table and lifts the holding unit to transfer the workpiece from the processing table onto the holding unit;
- and
- a fixing unit configured to fix the workpiece held by the holding unit and release the fixation of the workpiece when transferring the workpiece onto the processing table,
- wherein the fixing unit includes an abutting member that is movably supported so as to be capable of abutting on and separating from the workpiece, and an interlocking mechanism that presses the abutting member against the workpiece in conjunction with upward movement of the holding unit and releases the pressing of the abutting member in conjunction with downward movement of the holding unit.
A work transfer assembly comprising:
- a transferring mechanism capable of transferring a workpiece in predetermined carrying directions, the transferring mechanism including a rotation table that can be intermittently rotated;
- a plurality of processing tables arranged along the carrying directions of the transferring mechanism, respectively;
- and
- a plurality of work transfer apparatuses circumferentially spaced around the rotation table of the transferring mechanism,
- each of the work transfer apparatuses comprises i) a workpiece holding unit attached to the transferring mechanism, ii) a lifting and lowering unit that lowers the holding unit to transfer the workpiece held by the holding unit onto the respective processing table and lifts the holding unit to transfer the workpiece from the respective processing table to the holding unit, and iii) a fixing unit configured to fix the workpiece held by the holding unit and release the fixation of the workpiece when transferring the workpiece onto the respective processing table.

- a holding unit that is attached to the transferring mechanism and configured to hold the workpiece;
- a lifting and lowering unit that lowers the holding unit to transfer the workpiece held by the holding unit onto the processing table and lifts the holding unit to transfer the workpiece from the processing table onto the holding unit;
- and
- a fixing unit configured to fix the workpiece held by the holding unit and release the fixation of the workpiece when transferring the workpiece onto the processing table,
- wherein the lifting and lowering unit includes i) at least one guide rail that is fixed to the transferring mechanism, the at least one guide rail guides the lifting and lowering frame to allow the lifting and lowering frame to move up and down, and ii) a driving mechanism that is arranged in the transferring mechanism to provide driving force for lifting and lowering the lifting and lowering frame.
