It is provided toward the loading section 5 from the supply section. The slide rail 16 has a mechanism for changing its width.

On the other hand, the storage portion of the work pallet supply / storing mechanism 1 includes a carry-out path 13 (not shown in FIG. 1 and indicated by an arrow in FIG. 2 which is a plan view of the carrier changer 2) and an unloading portion 7 for palletizing. Treated work pallet group 1 on the pallet group 11 side of the supply section from the vicinity of the unloading frame 25 for moving the group 12 to the unloading path 13 and the unloading section 7.
It has a carry-out drive mechanism 15 for moving the device 2.

The carrier changer 2 is shown in FIGS.
As shown in FIG. 3, there are a loading unit 5, a work unloading unit 6, and an unloading unit 7, and a carrier 9 for moving a work pallet 8 is provided in each unit.

The carrier 9 is a plate-like member connected in an L shape, and as shown in the partial plan view of FIG. A work pallet holding frame 22 is formed around the portion 21, and is mounted on a rotary shaft 23 at a bent portion as shown in FIG. 2, and is controlled by a drive motor M1 to stop rotation. There is.

The loading section 5 has a slide rail 16 of the pallet group 11, holding claws 17 of the work pallet 8, and an elevator 18 having a lifter 20 for raising and lowering the work pallet 8 attached to the upper end. In addition, the elevator 18
A lifter 20 is attached to the tip of a lifting cylinder 19, and the holding claw 17 has a vertical movement mechanism and a claw opening / closing mechanism.

The operation of each part in the loading part 5 will be described below. As shown in the dotted line part in FIG.
It is carried onto the loading section 5 on the top 6. Pallet group 1
1 is held by a holding claw 17 and slide rail 16
The width of the work pallet 8 is expanded thereafter to secure a space for taking out the work pallet 8 from below. The carrier 9 is located below the slide rail 16, and the passing space 21 of the carrier 9
The lifter 20 stands by at a position higher than the carrier 9. The illustrated carrier 9 employs a system in which the work pallet 8 is moved by a rotary motion, but may be a system in which the work pallet 8 is moved by a linear motion.

After that, the elevator 18 rises, and the lifter 20 holds the pallet 8 at the bottom of the pallet group 11.
Here, the holding claw 17 releases the holding and moves up by one pallet, and the holding claw 17 holds the second work pallet 8 from the bottom while performing the closing operation of the claw, and the work pallet 8 above it. Support the whole. The lifter 20 descends as the elevator 18 descends, and at the same time, the holding claw 17 also returns to the initial position. Only the bottom work pallet 8 is a lifter 20.
Along with this, the work pallet 8 is held by the holding frame 22 of the carrier 9, and the lifter 20 retracts below the carrier 9. This state is shown in the partial sectional view of FIG.

Next, the carrier 9 is rotated 90 degrees to the right to move the work pallet 8 to the work unloading section 6. Also when loading the second work pallet 8, the lifter 20 moves up to support the loaded work pallet 8 and hold the holding claws 17.
The same operation is performed after is released.

Also in the work take-out section 6, an elevator 18 having a lifter 20 attached to the upper end is arranged below the carrier 9, and a holding pawl 17 similar to the loading section 5 is arranged. However, the holding claw 17 of the work take-out portion 6 does not have a vertical movement mechanism, but is equipped with a horizontal movement mechanism 24 instead.

The operation of the work unloading section 6 will be described. When the work pallet 8 is carried by the carrier 9, the elevator 18 installed below the stop position of the carrier 9 operates and the lifter 20 moves up. When the lifter 20 reaches above the passing space 21 of the carrier 9, the work pallet 8 moves above the holding frame 22 of the carrier 9. At this time, the holding claw 17 horizontally moves and approaches the work pallet 8, and the work pallet 8 is held by the operation of closing the claw. After that, the holding claw 17 moves the pallet 8 so that the first row of the workpiece to be taken out is located at the suction position of the pick and place mechanism 3. Then, when one row is sent to the cleaning zone, the holding claw 17 moves the pallet 8 so that the second row of workpieces is located at the pick and place position.

The pick-and-place mechanism 3 attracts and moves a work and is not different from the one normally used. The work placed on the work pallet 8 of the work unloading section 6 is picked up and moved to a predetermined position on the rotary table 4, and the cleaned work is picked up from the rotary table 4 and the work pallet 8 of the work unloading section 6 is picked up. It may be any one that can be moved to the predetermined position.

The rotary table 4 is provided with a clamp claw 26 for the work, and the work clamp position is stopped in the cleaning zone below the high-pressure water cleaning device 27, and at this time, the high-pressure water cleaning device 27 is placed on the work. Move horizontally to wash the work.

The cleaned work is returned to the work pallet 8 of the work unloading section 6 by the pick-and-place mechanism 3, and the work pallet 8 is again placed in the holding frame 22 of the carrier 9 by the reverse process. The carrier 9 on which the processed work pallet 8 is placed rotates 90 degrees to the right and stops at the unloading section 7.

Also in the unloading section 7, the elevator 18 is installed below the stop position of the carrier 9.
A holding claw 17 is installed above the carrier 9 stop position with a vertical movement and a mechanism for opening and closing the claw, and the pallet group 12 is held on the holding claw 17.

The operation of the unloading section 7 will be described. The work pallet 8 carried by the carrier 9
Is lifted by the lifter 20 of the elevator 18 and is held by the holding claw 17 immediately before the work pallet 8
The entire work pallet 8 of the unloading section 7 is held by the lifter 20. At that time, the holding claw 17 is released, descends to the position of the work pallet 8 which is newly added from below, and is closed to hold the work pallet 8 again. After that, the holding claw 17 rises to a predetermined position and stands by.

When a predetermined number of work pallets 8 are stacked by repeating this process, the carry-out plate 25 is inserted under the holding claw 17, the holding claw 17 is released, and the pallet group 12 is held by the carry-out plate 25. Then, the carry-out plate 25 carries out the carry-out path 1 of the work pallet supply and storage mechanism 1.
Moved to 3. In the carry-out path 13, the carry-out drive mechanism 15 moves the carry-out plate 25 in a direction orthogonal to the moving direction. In this way, the series of operation procedures shown in FIG. 5 is completed.

[0023]

As described above, according to the present invention, the transfer means of the work cleaning apparatus does not transfer the work itself but the work pallet. Therefore, most of the transfer obstructs the work fixing means. It was possible to reduce the size of the work cleaning device without the need. Furthermore, it became an inexpensive work cleaning device that can be used for other types as long as the work can be arranged on the pallet.
