BACKGROUND ART Since there are multiple types of jigs for the above-mentioned pallets depending on the type of workpiece, multiple types of pallets with different sizes and mounting shapes are prepared. In the past, pallets were transported by a cart (unmanned cart) and passed to a fixed washing machine, and after the desired cleaning was performed, they were returned to the cart and transported to the next process.

Problems to be Solved by the Invention According to the conventional configuration described above, a number of cleaning machines were required depending on the type of pallet, a large installation space had to be secured, and the equipment cost was high. .

Means for Solving the Problems In order to solve the above-mentioned problems, the cleaning equipment of the present invention is provided with a traverser that supports and conveys a pallet with a jig attached thereto on a fixed path. A plurality of reversing devices corresponding to the pallets are arranged in parallel along the fixed path, and these reversing devices have supporting parts that hold the pallets from the traverser and are swingable between a horizontal position and an upright position. A cleaning machine is provided on a side opposite to the traverser side with the reversing device inside, and a cleaning chamber forming main body of the cleaning machine is configured to be movable along the fixed path.

Effect According to the configuration of the present invention described above, by moving the traverser supporting the pallet,
This pallet can be passed to a reversing device depending on its type. After moving the cleaning chamber forming main body to face the reversing device that holds the pallets, the supporting portion of the reversing device is raised and swung to move the held pallets into the cleaning chamber forming main body. The pallet and the jig can be cleaned as desired. Moreover, the pallet after washing can be returned to the traverser again.

As shown in FIGS. 1, 2, and 6, the cleaning machine 12 has a main body 71 forming a cleaning chamber 70 placed on a rail 73 via a guided body 72, and a machine frame 74. By actuating a cylinder device 75 provided between the two, it is possible to freely reciprocate along the fixed path 14. The main body 71 has a box shape and is equipped with a cleaning oil nozzle, an air nozzle, etc. inside, and an entrance 76 for the pallet 40 etc. on the front side.
is formed. Furthermore, in the front, there is a doorway 76.
A shutter 77 for opening and closing a part of the cylinder is provided, and the shutter 77 is opened and closed by a cylinder device 79 via a wire 78.

Next, the operation of the above embodiment will be explained. For example, pallets from processing equipment (including jig 41, etc.) 40
The trolley 16 on which is mounted travels unmanned on the travel route 15 and stops with its sides facing each other on the traverser 13. Next, the pallet 40 on the truck 16 is transferred onto the roller conveyor device 27 of the traverser 13 while the stopper 29 is retracted by operation from the truck 16 side. At this time, the roller conveyor device 2
7 is force driven and therefore pallet 4
0 is forcibly retracted until it comes into contact with the stopper 30. Cart 16 empty after transferring pallet 40
is run on the running route 15 to the next process. The traverser 13 that has received the pallet 40 travels on a fixed path 14 and is stopped facing a reversing device 50 that corresponds to the type of pallet 40 that has been received. At this time, the movable base 53 is in a horizontal position, and the driving rotary body 32 is in pressure contact with the passive rotary body 62. Furthermore, the main body 71 of the washer 12 is moved and stopped with the entrance/exit 76 facing the reversing device 50 . After the stopper 30 is retracted in this state, the roller conveyor device 27 is driven by the forward/reverse drive device 28, and the roller conveyor 61 is also driven via both the rotating bodies 32, 62. As a result, the pallet 40 is transferred onto the roller conveyor 61 and is stopped by contacting the stopper 65.
At this time, the engaging portion 44 is externally engaged with the locking piece 63. At this time, the engagement pin 59 is in the lowered position as shown by the imaginary line in FIG. This results in the state shown by the solid line in FIG. 1. Next, the movable table 53 is erected and swung by the operation of the cylinder device 54, and the jig 41, pallet 40, etc. are thrust into the cleaning chamber 70 through the entrance 76 as shown by the imaginary line in FIG. Then lower the shutter 77,
The shutter 77 and the cover plate 64 close the entrance/exit 76. In this state, the jig 41, the pallet 40, and the workpiece are cleaned as expected by the cleaning oil sprayed from the cleaning oil nozzle.
Remove chips, etc. At this time, the rotary drive device 58 is operated to rotate the pallet 40 and the jig 41 together with the rotary table 57 about the axis 66, so that cleaning is performed over the entire surface. After performing the desired cleaning, air is injected from the air nozzle to dry (remove oil).

After performing such washing and drying processing, the pallet 40 and the like are returned onto the traverser 13 by a reverse action to that described above. Then, the traverser 13 is run and connected to the warehousing conveyor device 7. The oil removal by drying described above is not sufficient due to the processing time and other factors, and the cleaning oil adhering during this running drips. The cleaning oil dropped at this time is received directly or by the oil pan 33 of the traverser 13. The pallets 40 on the traverser 13 are transferred to the storage conveyor device 7, and the target compartment storage space 2 is created by a combination of the movement of the loading/unloading device 5, the lifting/lowering of the lifting platform 10, and the moving in and out of the loading/unloading tool 11. is stored in. Note that oil pans are also provided at the lower part of each storage space 2 and the lower part of the warehousing conveyor device 7, respectively. The pallets 40 in the shelf 3 are taken out to the unloading conveyor device 8 by the reverse action of the loading/unloading device 5, and then transferred to the cart 16 and then conveyed to the next process.

Effects of the Invention According to the cleaning equipment of the present invention having the above configuration,
By moving the traverser supporting the pallet, the pallet can be transferred to a reversing device depending on its type. After moving the cleaning chamber forming body to face the reversing device that holds the pallets, the supporting portion of the reversing device is erected and swung to push the held pallets into the cleaning chamber. , the pallets and jigs can be cleaned as desired. Moreover, the pallet after cleaning can be returned to the traverser again. As described above, according to the present invention, various types of pallets can be washed with one washing machine, the installation space can be narrowed, and the equipment cost can be kept low.
