JPS60197343A - Pallet inverting washing device - Google Patents

Abstract

PURPOSE:To enable a washing device to efficiently eliminate the necessity for an operator washing chips, by injecting washing fluid to an inverted pallet from its bottom side. CONSTITUTION:A washing device 14, juxtaposing beside a pallet changer, provides both a pallet base 1 and additionally a clamp mechanism 7 for a pallet 2 on the pallet base, while provides an inverting mechanism 4 which vertically inverts the pallet base. Then the washing device 14 sets injection devices 6 for injecting washing fluid toward the pallet from its bottom side when the pallet is inverted. In this way, the necessity for an operator washing chips relating to the pallet and a work can be easily eliminated by inverting the pallet 2 together with the pallet base 1 further injecting the washing fluid so as to sweep the pallet.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pallet reversal type cleaning device for removing incidental materials such as chips generated during machining of a workpiece machined in a machining center.

Conventionally, chips from workpieces mounted on jig pallets were removed by blowing or inhaling air on the table of the machining center, but in machining that uses cutting oil, this treatment has not been fully accomplished. Instead, workers were disposing of chips at the setting site.

In such a method, the production process cannot be automated, and there is a problem in that the production process reduces work efficiency.

The present invention has been made to solve the above-mentioned problems.

The following description will be given based on the embodiment shown in the drawings.In FIG. 1, 1 is a pallet base, 2 is a pallet, 3 is a workpiece mounting jig, 4 is a reversing cylinder, 5 is a cleaning fluid supply pipe, 6 is also the injection nozzle, 7 is the auto coupler, 8 is the cover, 9 is the cleaning fluid receiver, 10 is the suction tank conduit, 11 is the chip conveyor, and 12 is the conveyor 1.
1 is a drive motor, and 13 is a chip receiver.

These 1 to 13 are members constituting the cleaning device 14.

Reference numeral 15 in FIGS. 2 and 3 indicates a pallet base, which is of the pallet changer 16. In addition, 1
7 is a piston, 18 is a piston rod, 19 is a rack,
20 is a pinion, 21 is a bearing, 22 is a stopper with a limit switch, and 23 is a workpiece.

According to the present invention, a pallet changer 16 is provided beside the cleaning device 14, and the cleaning device 14 is provided with a pallet base 1, and a clamping mechanism for the pallet 2 is attached to the pallet base. The auto coupler 7 controls the clamping mechanism. A reversing mechanism is provided for vertically reversing the pallet base together with the clamped pallet, and the reversing cylinder 4 is the main component thereof. A cleaning fluid (liquid or compressed air) injection device is installed from below toward the pallet 15 during inversion. Infeed pipe 5 in the figure. The injection nozzle 6 is a member thereof, and the inlet pipe 5 is connected to a pump.

The present invention is configured as described above, and a workpiece processed in a machining center is placed on a pallet and transferred onto a pallet base 1 by the action of a robot.

Thereupon, the pallet is clamped to the pallet base 1 and is inverted together with the pallet base 1 by the reversing cylinder leader 4, and when the pallet is inverted, the chips fall down, but those still attached are swept away by a jet of cleaning fluid.

As can be easily imagined from the progress of the cleaning process described above, the present invention allows cleaning of chips from pallets and workpieces to be extremely easily unmanned in the technical field related to unmanned production processes that are currently being implemented. This is a conflict that can lead to achieving the goal.
