Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning device for cleaning a work piece.

[0002]

2. Description of the Related Art Conventionally, for cleaning a workpiece, the workpiece is placed on a pallet and the workpiece is cleaned together with the pallet. That is, as shown in FIG. 8, the stacker crane 1 that moves between the rails 104 installed up and down.
02 is a temporary placement table 101 installed on the entire surface of the cleaning apparatus 100.
Then, the pallet P on which the workpiece is placed is carried into the temporary placement table 101. The pallet P loaded into the temporary placing table 101 is loaded into the cleaning device 100 by the pallet loading / unloading device 103 provided between the temporary placing table 101 and the cleaning device 100. When the pallet P is carried into the cleaning device 100,
By closing a cover (not shown) on the front surface of the cleaning device 100, the work placed on the pallet P is cleaned.
As shown in FIG. 9, the stacker crane 102 used at this time is provided with a vertically movable lift device 102a on a stacker crane main body 102 that can travel between travel rails 104 installed vertically. A fork device 102b having a fork table 102c on which the pallet P is placed is provided on the lift device 102a, and the fork table 102c is moved in a direction perpendicular to the traveling direction of the stacker crane 102 by driving the fork device 102b. It is designed to let you. Then, the lift device 102a and the fork device 102
By the operation of b, the pallet P on which the workpiece is placed is carried in and out.

[0003]

However, the above-described conventional cleaning device 100 has the following problems. That is, since the temporary table 101 is provided, the installation space becomes large. In addition, from the temporary table 101 to the cleaning device 100
In addition, there is a problem in that the pallet loading / unloading device 103 for loading the pallet P on which the workpiece is loaded is required, which makes the device expensive.

Therefore, it is considered that the pallet P is directly carried into the cleaning device 100. However, when the cleaning device 100 cleans a workpiece placed on the pallet P, the cleaning device 100 rotates or changes the posture of the workpiece. Further, a clamping device for clamping the pallet P is provided. This clamp device is made by engaging a clamper with a recess provided on the back surface of the pallet P and clamping it with respect to a standard pallet. However, as shown in FIG. 9, the fork device 102b of the stacker crane 102 is Since the fork table 102c supports the central portion of the back surface of the pallet P, the fork table 102c interferes with the clamp device, and the pallet P cannot be directly loaded into the cleaning device 100 from the stacker crane 102.

[0005]

It is fixed at 32. Further, a delivery table 50 for delivering the pallets P is fixed to the upper surface of the turning table 37. A cover 75 is fixed to the tilt table 32 to cover the swivel table 37, the delivery table 50 and the like from the side, and the tilt table 32 and the cover 75 are washed when the tilt table 32 is swung to a vertical position. It is adapted to act as a front cover for the device 30.

A slide cover 61 is provided on the front upper portion of the cleaning device main body 31. This slide cover 61
After swinging the tilt table 32 to bring the pallet P into the cleaning device 30, it slides downward to close the gap between the opening of the cleaning device 30 and the cover 75, so that the coolant liquid can be discharged outside when cleaning the pallet P. It is designed not to leak. In addition, inside the cleaning device main body 31, the nozzle 7
0, a shooter 63 and a chip conveyor 64 are provided. The nozzle 70 injects the coolant liquid supplied by a coolant liquid supply device (not shown). The shooter 63 removes the coolant liquid generated by the cleaning and the chips adhering to the pallet P from the chip conveyor 6
It is supposed to be collected in 4.

Next, the structure of the delivery table 50 will be described with reference to FIGS. As shown in FIG. 5, a delivery table 50 is fixed on the turning table 37. Four clamp cylinders 51 for clamping the pallet P are fixed to the delivery table 50. A shaft 54 passes through the inside of the clamp cylinder 51, and a groove mechanism (not shown) allows the shaft 54 to move in the vertical direction in the drawing and to rotate about the vertical axis. Then, the clamper 52 having the claws 52a fixed to the tip of the shaft 54 is moved up and down while rotating. Further, a support table 53 is fixed to the upper surface of the delivery table 50, and the inner concave portion of the pallet P carried on the support table 53 and the clamper 52 engage with each other to clamp the pallet P to the delivery table 50. It is supposed to do. That is, as shown in FIG. 6A, when loading and unloading the pallet P, the shaft 54 is raised to rotate the pawl portion 52a in the pallet loading direction so that the clamper 52 does not interfere with the pallet P. Figure 6
As shown in [B], when the pallet P is clamped, the shaft is lowered to rotate the claw portion 52a to the outside of the pallet P.

Next, the structure of the turning table drive unit 40 will be described with reference to FIG. Turning table drive device 4
0 is composed of a base portion 40a, a cylinder 41, a shaft 42, a turning shaft 44, a rack 43, and a pinion 45. A swivel shaft 44 rotatably supported by the base 40a

Is equipped with a pinion 45, and this pinion 45
A rack 43 meshes with the. The rack 43 is fixed to the shaft 42 of the cylinder 41.
Is driven to move the shaft 42 in the left-right direction in the drawing, thereby rotating the revolving shaft 44 and revolving the revolving table 37.

Next, the operation of the cleaning apparatus of this embodiment will be described. The stacker crane 10 loaded with the pallet P on which the workpiece is placed is moved to the front of the cleaning device 30. At the same time, the lift drive device 16 is driven to position the height of the pallet P above the delivery table 50 on the tilt table 32 in the horizontal position of the cleaning device 30. And
The fork 20 of the stacker crane 10 is driven, the pallet P is moved onto the delivery table 50, and the lift lifting / lowering drive device 16 is driven to lower the lift table 14. When the fork 20 is returned to the stacker crane 10, the pallet P is placed on the support base 53 of the delivery table 50,
The loading of the pallet P onto the tilt table 32 is completed.

Next, the clamp cylinder 5 of the cleaning device 30
1 is driven to fix the pallet P to the delivery table 50. Subsequently, the cylinder 33 is driven to drive the tilt table 3
2 is swung to a vertical position to move the pallet P to the cleaning device main body 31.
Bring it in. Lower the slide cover 61 . Then,
The tilt table 32 in the vertical position, the cover 75 and the slide cover 61 act as a front cover of the cleaning device 30 so that the coolant used for cleaning and the cutting chips attached to the workpiece do not leak outside. Has become. Then, the cylinder 41 is driven to turn the turntable 37. Coolant liquid is jetted from the nozzle 70 to generate a pallet P.
The work placed on is cleaned.

The cleaning apparatus of this embodiment is provided with the tilt table 3
By providing the revolving table 37 for revolving the pallet P on which the workpiece is placed on the work piece 2, it is possible to further easily remove the facets that have not adhered to the workpiece and to effectively wash the workpiece.
