The lifting frame 11 of the lifting device 10 has three gate-shaped frames inside the frame 6, and each immersion tank 1,
2 and 3, and a rotation shaft 12 is supported horizontally via a bearing at the lower end of each portal frame of the elevating frame 11.
As shown in FIGS. 3 and 4, a pinion 13 is attached to the outer end of each rotating shaft 12, respectively.
Reference numeral 14 denotes a rack that meshes with each pinion, and the rack 14 is vertically slidably held by a guide member 15 vertically attached to the elevating frame 11, and further includes:
The rack 14 is connected to the piston rod of a hydraulic cylinder 16 mounted downwardly on the lifting frame 11. Furthermore, the dividing rails 4a, 4b, or 4
c is fixed and the elevating frame 11 is lowered, the dividing rails 4a, 4b, 4c rotate about 360 degrees about the rotation shaft 12 by the pushing operation of the fluid pressure cylinder 16. The fluid pressure cylinder 16, the rack 14, the pinion 13, etc. constitute a driving means for rotating the dividing rail, and this driving means is installed on the front and rear sides of the three portal frames of the elevating frame 11, respectively. rail 4
a, 4b, and 4c are rotated by drive means provided for rotation shafts on both sides, respectively. In addition, lock pins 18 are provided on both sides of each dividing rail 4a, 4b, and 4c so as to protrude inward as locking means for holding the net container 5 on the rail.

Next, the operation of the cleaning device will be explained. First, the mesh container 5 containing the cleaning items is placed on the right end of the rail 4 in FIG. 1 with its lid securely closed and locked. Due to the low speed rotational drive of the chain conveyor 7, the backing rod 8 pushes the net container 5 and advances to the left, and when the net container 5 reaches a fixed position on the dividing rail 4a,
This is detected by a limit switch (not shown) or the like, and the chain conveyor 7 is stopped. continue,
The fluid pressure cylinder 19 operates to cause the lock pin 18 to protrude inside the dividing rail 4a, and the protrusions 5a at the four corners of the net container 5 are connected to the lock pin 18 and the dividing rail 4a.
The net container 5 is held on the dividing rail 4a by being held between the two. Next, when the hydraulic cylinder 23 of the lifting device 10 pushes out the piston rod and operates, the lifting frame 11 is moved through the suspension chain 21.
moves up and down, the dividing rail 4a enters the dipping tank 1 while holding the net container 5, and the cleaning items in the net container 5 are immersed in the cleaning liquid in the dipping tank 1. In this state, when the fluid pressure cylinder 16 attached to the lifting frame 11 performs a pushing operation, the rack 1
4. The rotating shaft 12 rotates approximately 360 degrees via the pinion 13, thereby separating the separating rail 4a and the net container 5.
rotates about one rotation in the immersion tank 1, and then when the fluid pressure cylinder 16 pulls back to its original position, the rotating shaft 12 rotates about 360 degrees in the opposite direction again.
The net container 5 is moved in the opposite direction again together with the dividing rail 4a.
Rotate and return to the original horizontal position. In this way, the net container 5 is rotated within the dipping tank 1 an appropriate number of times by the operation of the fluid pressure cylinder 16, thereby cleaning the internal cleaning section.

When the cleaning process in the immersion tank 1 is completed, the hydraulic cylinder 23 of the lifting device 10 performs a pullback operation and the lifting frame 11 is lifted up. By operating the fluid pressure cylinder 16 and rotating the net container 5 in the air, the cleaning liquid and the like accumulated in the cleaning object in the net container 5 will fall, allowing for good drainage.

Thereafter, when the fluid pressure cylinder 23 of the lifting device 10 is completely pulled back to its original position, the dividing rail 4a holding the net container 5 moves up and down, and returns to its original state with the stopper 9 in contact with the end of the rail 2. Returning to the horizontal position, the lifting device 10 stops. and,
When the hydraulic cylinder 19 operates to pull back its piston rod and the lock pin 18 is retracted to the outside of the dividing rail 4a, the holding of the net container 5 is released.
The chain conveyor 7 starts again, and the dividing rail 4
The mesh container 5 on a is connected to the dividing rail 4 on the next dipping tank 2.
It is pushed and conveyed by the push rod 8 until it reaches above b. Thereafter, by repeating the same operation as above, the net container 5 is immersed in the dipping tank 2, and the net container 5 is immersed in the dipping tank 2.
The items in the mesh container 5 are washed again by the hot water inside. Then, the mesh container 5 is further placed in the dipping tank 3, and after the washed items in the mesh container 5 are dried by blowing hot air, etc., the chain conveyor 7
taken from the end of the During this time, net containers 5 containing new items to be washed are sequentially carried into the dipping tanks 1 and 2, and the same cleaning process as described above is repeatedly and continuously carried out by repeating the above-described operations.

In the above embodiment, fluid pressure cylinders were used for raising and lowering the lifting frame 11, rotating the dividing rails 4a, 4b, and 4c, and operating the lock pin 18, but motors, electromagnetic actuators, etc. may also be used. You can also do it.

<Effects of the Invention> As explained above, according to the cleaning device of the present invention, since it is configured as described above, net containers containing cleaning items are sequentially fed into a plurality of immersion tanks, and can be raised and lowered accurately. Since the net container can be immersed and the net container can be rotated within the dipping tank, the cleaning effect can be improved by rotating the cleaning items in the net container within the dipping tank. Furthermore, if the net container is rotated at the top of the dipping tank where there is no cleaning solution while the net container is being pulled up, the water from the cleaning items can be drained better, and if the net container is rotated in the dipping tank where hot air is blown, Washed items can also be dried efficiently.
