AI Technical Summary

Technical Problem

Existing workpiece transfer devices and machine tools face complications in mechanism and control due to differing timings and strokes for opening and closing intermediate shutters, leading to increased manufacturing costs and limited separation distance between the workpiece holding device and cover.

Method used

A workpiece transfer device with a workpiece holding device and a cover that moves integrally within the processing area, where the holding device movement section is longer than the cover movement section, and a coupling mechanism for separation and integration, along with a biasing device to increase separation distance.

Benefits of technology

Enhances the separation distance between the workpiece holding device and cover, simplifies the mechanism and control, reduces manufacturing costs, and improves workpiece transport freedom while minimizing contamination risk.

Abstract

To provide a workpiece transport device which may increase a separation distance between a workpiece holding device and a cover, and to provide a machine tool.SOLUTION: A workpiece transport device 1 includes: a workpiece holding device 10 which holds a workpiece W in a processing area 111 where the workpiece W is processed and may move between a non-processing area 113 located adjacent to the processing area 111 and the processing area 111; and a cover 20 which shields the processing area 111 from the non-processing area 113 and may move at least in the processing area. The cover 20 moves integrally with the workpiece holding device 10 when moving in the processing area 111 and a holding device moving section WL, which is a section where the workpiece holding device 10 may move, is longer than a cover moving section CL, which is a section where the cover 20 may move.SELECTED DRAWING: Figure 2
