Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a centerless grinding machine, and in particular to the arrangement structure of its operation panel.

Prior Art The operation panel of a centerless grinding machine basically requires various switches that are operated during operation of the machine and a display device that shows the operating status of the machine.
Various switches are required for setting up the equipment and manually dressing the grinding wheel.

In a conventional centerless grinding machine, a single operation panel including all of these switches and a display device was placed at the front of the machine, that is, on the work supply side.

Problems that the invention aims to solve By the way, in the actual operation of a centerless grinding machine, setup work is usually done at the front of the machine, but once the machine starts operating, The main task of the operator is to check the machining length of the workpiece discharged from the device, and the worker is often located behind the device, that is, on the workpiece discharge side. In addition, the main shaft (grinding wheel axle) casing is equipped with a see-through window so that you can check the behavior of the dressing blade during dressing of the grinding wheel. During manual dressing work, use this see-through window to check the operation of the dressing device. It is also necessary to do some work.

However, in conventional centerless grinding machines, the operation panel with all the switches and display devices was installed near the workpiece supply position on the front of the machine, so it was difficult to operate the switches or change the operation of the machine. When checking the status, it is necessary to go to the front of the device one by one, and when checking the operation of the dressing blade during manual dressing work, one must move one by one to the position of the transparent window located away from the operation panel. This not only makes these operations complicated, but also poses a problem in that it is difficult to promptly take appropriate measures depending on the processing state of the workpiece and the operating state of the device.

The purpose of this invention is to solve the above problems and provide a centerless grinding machine with better operability.

Means for Solving the Problems This invention is based on the idea that in centerless grinding machines, the main operation panel 2, which was conventionally placed on the workpiece supply side F at the front of the device 1, is placed behind the device, that is, on the workpiece discharge side R. It also proposes that the control panel, which was previously only installed in one place, be distributed,
A second operation panel 3 equipped with switches C' necessary for setup work of the device 1 is installed on the work supply side F where the main operation panel was previously installed, and switches D necessary for manual dressing work are installed. It is proposed that the third operating panel 4 be placed near the see-through window 15 for checking the operation of the dressing blade 16.

The main operation panel 2 placed on the workpiece discharge side includes at least switches A that are operated while the device 1 is operating.
and a display device B that shows the operating status of the device 1, and in addition, all or some of the switches C' for setup work provided on the second operation panel 3 on the workpiece supply side are provided. It is preferable to provide it also on the operation panel 2 from the viewpoint of operation.

Operation The centerless grinding machine 1 has an open space on the workpiece supply side F of the device due to its structure and the need to install the workpiece supply device adjacent to it.
Therefore, during setup that requires position adjustment work of the adjustment grinding wheel 27 and work rest 23, the work supply side F
It is convenient to do it from In this invention, the second operation panel 3 equipped with switches C' for setup work is arranged on the workpiece supply side F of the device, so that the setup work of the device 1 can be performed on the workpiece supply side F in the same way as in the conventional device. It can be done from

Furthermore, during setup work, it is necessary to test the workpiece and check its machining status.For this purpose, the operator must grind the workpiece on the workpiece discharge side R of the equipment.
I have to go to In this invention, if an embodiment is adopted in which switches C for setup work are also provided on the main operation panel 2 installed on the workpiece discharge side R of the device, the operator who goes behind the device 1 can continue to work as it is. Since the setup work can be continued at the same location, the efficiency of the setup work is greatly improved.

Once the setup work is completed and the device 1 enters the steady operation state, the worker's main task is to check the machining status of the workpiece, as described above, and the worker is mainly located behind the device 1. . In this invention, the main operation panel 2 equipped with switches A that are operated while the device 1 is in operation and a display device B that shows the operating status of the device 1 is located on the workpiece discharge side R of the device. can constantly monitor the operating state of the device 1 while checking the machining state of the workpiece, and necessary operations can be performed immediately from the same position without having to go around the front of the device 1.

Furthermore, during manual dressing work, the operator can check the behavior of the dressing blade 16 through the see-through window 15 while operating the switches D on the third operation panel 4, and take prompt action in the event of trouble. becomes possible.
