  However, the lifting / lowering means 14 of the wet processing apparatus in FIG. 3 has a swinging motion within a variable range in the vertical direction when the vertical moving plate 12 is lifted and lowered, and enables more effective cleaning. Therefore, there is a problem that the response of the quick vertical movement is poor, causing a trouble and shortening the life of the motor or the cylinder.

  Further, as shown in FIG. 3, the drive source 18 of the conveying means 16 is disposed on the carry-in side where the frame 22 is indicated by the direction A, and the conveying belt of the conveying means 16 is driven in the rotational direction indicated by the direction B. For this reason, the frame 22 is not drawn, but is sent out. For this reason, there has been a problem in that bending due to the elongation of the belt or the like occurs at the time of conveyance, causing a conveyance trouble. Further, since the conveying means 16 does not have a conveying belt guide mechanism, there is a problem that meandering occurs due to the bending of the belt during conveyance. The module main body 10 has a problem that the maintenance space is narrow and the operation is difficult only by providing a minimum door (not shown) in order to keep the internal state clean.

  The present invention has been made to solve such problems, and an object of the present invention is to provide a wet cleaning apparatus that has a swing mechanism that maintains stable operation and a transport mechanism, and that is easy to maintain. There is.

  The wet cleaning apparatus of the present invention is a wet cleaning apparatus for automatically transporting an object to be cleaned to the upper part of the cleaning tank and immersing it in the tank for cleaning. A vertical moving plate extending in a frame shape around the cleaning tank so that the central portion is opened and the cleaning tank is opened, and a thrust that moves up and down by being detachably provided on the vertical moving plate Elevating means for transmission, conveying means provided on both upper sides of the vertical moving plate, conveying the object to be cleaned, drive source for driving the conveying means, and conveying means placed on both upper and lower moving plates on the upper moving plate A frame body integrally formed on both sides and an upper portion, an installation portion that is suspended from the upper portion of the frame in the center and the object to be cleaned is suspended, and the installation portion is immersed in the cleaning tank And an oscillating means for oscillating the installation portion. The oscillating means comprises an eccentric cam, a cam follower, and a motor. Characterized by including the.

  The drive source for driving the transporting means of the wet cleaning apparatus of the present invention is arranged on the carry-out side of the transporting means in which the frame is carried into and out of the transporting means.

  The conveying means of the wet cleaning apparatus of the present invention comprises a belt receiving plate that guides the conveying belt, and the belt receiving plate has a bottom plate that contacts the belt surface of the conveying belt when the conveying belt is bent, and a conveying belt. And a side plate installed on both sides of the bottom plate that contacts both ends, and the bottom plate has a slit for reducing an area in contact with the belt surface.

  The wet cleaning apparatus of the present invention has a box-shaped module body that encloses and houses a cleaning tank, a vertical moving plate, a lifting and lowering means, a conveying means, a drive source, and a swinging means. It is divided into two and the upper part can be opened.

Accordingly, it is possible to provide a wet cleaning apparatus that has a swing mechanism that maintains stable operation and a transport mechanism and that is easy to maintain.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram showing a configuration of a wet cleaning apparatus according to the present invention. In FIG. 1, an elevating means 14 that is detachably provided on the vertical moving plate 12 and transmits a thrust force that moves up and down is disposed on the direction A side in which the frame body 22 is carried in, and a drive source 18 of the conveying means 16 The conveying means 16 that is disposed on the side where the body 22 is carried out and is provided on both upper sides of the vertical moving plate 12 and conveys an object to be processed includes a belt receiving plate 40 (not shown) that guides the conveying belt. However, it is different from FIG. Further, the arrangement of the elevating means 14 is not limited to the direction A side in which the frame body 22 is carried in, and the drive source 18 may be directly connected to the rotating shaft 16a.

  Further, the module main body 11 is different from that shown in FIG. 3 in that the module main body 11 can be opened by being divided into two parts (not shown). Further, the wet cleaning apparatus according to the present invention has a swinging means 30, and the swinging means 30 includes an eccentric cam 30, a cam follower 35, and a motor 32. FIG. 2 is a structural diagram showing the structure of the belt backing plate of the wet cleaning apparatus of the present invention. In FIG. 2, the belt receiving plate 40 is installed on both sides of the bottom plate 42 that contacts the belt surface of the conveyor belt when the conveyor belt extends, and both sides of the bottom plate that contacts both ends when the conveyor belt extends and bends. The bottom plate 42 has a slit 46 for reducing the area with which the belt surface comes into contact.

  In FIG. 1 again, when the frame 22 is carried in from the direction A to the carry-in side of the carrying means 16, the drive source 18 is arranged on the side from which the frame 22 is carried out, and the carrying belt is rotated in the rotation direction indicated by the direction B. Since the frame 22 is driven, the frame body 22 is driven in the direction attracted to the drive source 18 and is carried out. For this reason, even if the belt stretches during conveyance, the belt on the side carrying the frame body 22 does not bend, and a conveyance trouble due to the bending does not occur.

  Further, the belt receiving plate 40 of the conveying means 16 shown in FIG. 2 can suppress the occurrence of bending by bringing the belt surface extended of the conveying belt into contact with the bottom plate 42. Furthermore, even if the bending occurs, the amplification of the bending is prevented by bringing both ends of the conveyor belt into contact with the side plate 44. The bottom plate 42 has a slit 46 for reducing the area in contact with the belt surface. For this reason, the frictional resistance caused by the contact is reduced, so that the driving force of the driving source 18 is not impaired. The side plate 44 has a tapered shape on the side where the frame body 22 shown in the direction A is carried. For this reason, it is possible to reduce the trouble that the conveyed frame body 22 collides with the side plate 44 and the conveyance stops.

  The oscillating means 30 is disposed in the vicinity of the elevating means 14. When the elevating means 14 lowers the vertical moving plate 12 and lowers the installation portion 24 until it is immersed in the central portion of the cleaning tank 19, the cam follower 35 of the swinging means 30 receives the vertical moving plate 12. At this time, the elevating means 14 is further lowered to a predetermined position. When the cam follower 35 receives the up-and-down moving plate 12, the eccentric cam 32 is rotationally driven by the motor 37, and the cam follower 35 is moved up and down with a predetermined stroke to swing the installation portion 24.

  By exchanging the eccentric cam 32 and the motor 37, it is possible to cope with changes in the swing stroke, swing speed, load of the installation section 24, etc., eliminating the cause of trouble and extending the life of the motor. Extend. Since the module main body 11 is divided into two upper and lower parts, the upper side is opened at the time of component replacement corresponding to the operating conditions or maintenance of the transfer system and the cleaning tank, so that a sufficient work space can be secured. Become.

  As described above, according to the present invention, a stable cleaning process can be performed by the swing mechanism by the eccentric cam and the optimal arrangement of the drive source and the transport mechanism having the belt receiving plate, and the upper and lower parts are divided into two.
