Means, a switching valve provided in the supply means for selectively switching the cleaning liquid and the air to be supplied to the cleaning chamber, and the supply hand to the stored workpieces disposed in the cleaning chambers. A plurality of common nozzles that inject air into each of the workpieces instead of the cleaning liquid under the control of the switching valve after injecting the cleaning liquid supplied from the pair of cleaning chambers in parallel with each other. It is characterized in that substantially the same works conveyed along the extending work conveying path are simultaneously taken in under the driving action of the second actuator, and are subjected to cleaning and drying actions.

[Operation] In the present invention, the pair of workpieces conveyed on the pair of workpiece conveying paths extending in parallel are grasped by the clamp means under the action of the first and second actuators and introduced into the pair of cleaning chambers. After that, for each of the workpieces, a cleaning liquid is selected by a switching valve, the cleaning liquid is jetted from a common nozzle to perform cleaning, and then air is selected by the switching valve to jet the air from the common nozzle. Then, the workpieces are dried, and then each workpiece is returned to the workpiece conveying path by the clamp means.

Reference numerals 58a and 58b denote operation switches for the cleaning chambers 16a and 16b, respectively. Belt conveyors 60a and 60b that convey the objects to be cleaned are disposed in front of the respective cleaning chambers 16a and 16b.

FIG. 5 shows the nozzle 50 fixed to the partition wall 14. The nozzle 50 is divided into two pipes 70a and 70b and the respective pipes 70a and 70b.
Nozzle bodies 72a and 72b fixed to 0b. The nozzle bodies 72a and 72b face the cleaning chambers 16a and 16b, respectively.

An embodiment of the cleaning apparatus according to the present invention is basically constructed as described above. Next, its operation and effect will be explained.

First, the door opening / closing cylinder 20 is urged to open the door 22. Therefore, an object W to be cleaned such as a cylinder block conveyed through the respective belt conveyors 60a and 60b.
Is clamped from the left and right by clamping means 24, 24 on the front surface of the respective cleaning chambers 16a, 16b. In this case, the clamp cylinder 32 is urged, and the clamp gears 28 and 26 rotate to perform the clamp operation. That is, the protrusions 46, 46 of the clamping means 24, 24 are used to grip the object to be cleaned.

Next, the object W to be cleaned is taken into the cleaning chambers 16a and 16b through the clamp means 24 and 24 which are biased by the reversing cylinder 42 and rotate about the reversing shaft 38. After that, the door opening / closing cylinder 20 is urged, and the door 22 is closed again.
Therefore, based on the operation of the operation switches 58a and 58b by the operator, the solenoid valves 56 and 56 are switched and the pump 54 is energized, so that the object to be cleaned W in the cleaning chamber 16a is first moved from the nozzle main body 72a of the nozzle 50 to the cleaning object W. The cleaning water is jetted to cause the cutting debris to flow down to the hopper 52. Operation switch 58
The solenoid valves 56 and 56 are switched by operating a and 58b again, and air is jetted by the nozzle body 72a to blow off water droplets.

Next, the nozzle body 72b of the nozzle 50 sprays cleaning water onto the object W to be cleaned in the other cleaning chamber 16b, and then the solenoid valves 56 and 56 are energized again to spray air from the nozzle body 72b. After completion of the cleaning process and the drying process by blowing air, the door 22 is opened under the driving action of the door opening / closing cylinder 20, the reversing cylinder 42 is driven again to rotate the clamp means 24, and the object W to be cleaned is conveyed by the belt conveyor. Place on 60a, 60b.
This operation is performed by operating the operation switches 58a and 58b.
Each is done independently. That is, after the cleaning process and the drying process in one cleaning chamber 16a are completed, the other cleaning chamber
The washing and drying process for 16b is carried out.

As described above, according to the present embodiment, a plurality of cleaning chambers 16a and 16b that share the nozzle 50 are provided, and cleaning water and air are selectively jetted for each cleaning chamber 16a and 16b to be cleaned. Wash W individually. Therefore, the apparatus can be downsized and the cleaning action can be performed in an extremely short time.

In addition, the clamp cylinder 32 can be expanded and contracted for clamping means.
By rotating 24 horizontally for clamping and unclamping, and by expanding and contracting the reversing cylinder 42 to rotate the clamp means 24, the object W to be cleaned can be easily put in and taken out. Further, if the nozzle 50 is provided on the back surface of the door 22, the cleaning target W can be cleaned more effectively.

[Advantages of the Invention] According to the present invention, a work is stored in a pair of cleaning chambers arranged between a pair of work transfer paths, and then a cleaning liquid is sprayed onto each work through a common nozzle to perform cleaning. After
Air is jetted to each of the works through the common nozzle to dry the work, and the work is returned to the work conveyance path. In this case, since the cleaning liquid and the air are sprayed through the common nozzle and the pair of cleaning chambers are arranged between the work transfer paths, the number of constituent members is small and the size can be reduced. Further, unlike the prior art, it is not necessary to transfer the work from the cleaning process to the air blowing process to perform each work, and further, the cleaning work or the drying work is performed on the pair of works at the same time, which improves the work efficiency. Can be realized.
