Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is applied to positioning a workpiece being transported along a processing line and a processing machine arranged along the processing line. The present invention relates to a reference surface cleaning device.

[Conventional technology]

Nowadays, processing machines that perform machining such as cutting and grinding are arranged sequentially along a line, and workpieces are conveyed and moved along this line, and the workpieces are sequentially machined during that time, thereby increasing the workability of machining. I'm trying to improve.

In this type of processing line, in order to ensure the processing accuracy of the workpiece, a reference surface is placed at an appropriate position on the line, and the processing machine The workpiece is positioned relative to the

[Problem to be solved by the invention]

By the way, in the above-mentioned processing line, a large amount of chips are generated by performing machining such as cutting and grinding on the workpiece, and there is a possibility that the chips may adhere to the reference surface.

In such a case, it becomes impossible to accurately position the workpiece with respect to the processing machine, resulting in machining errors occurring in the workpiece.

For this reason, conventionally, a fluid such as air or a cutting curve is injected onto the reference surface, and the chips adhering to the reference surface are removed by the ejected fluid.

However, if the workpiece is positioned with chips remaining on the reference surface, these chips will stick to the reference surface.
As a result, it is difficult to remove the chips with the above-mentioned injection fluid such as air or cutting oil. In such a case, it is necessary to stop the machining line and scrape off the chips that have adhered to the reference surface. It won't happen.

SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide a cleaning device that can prevent machining errors of workpieces as much as possible without stopping a machining line.
