A pair of hard rolls 17 and 17 made of, for example, a synthetic resin material or a metal material such as duralumin are disposed.

  The hard roll 17 is formed so that its outer diameter is smaller than the outer diameter of the elastic water-absorbing roll 38, so that the hard roll 17 can be brought into pressure contact while shifting the contact position with the elastic water-absorbing roll 38. .

  In addition, a large number of grooves 18 are engraved on the peripheral surface of the hard roll 17 in a direction crossing or orthogonal to the rotation direction thereof, and these grooves 18 are repeatedly pressed against the elastic water absorbing roll 38 side. It is possible to exert a cleaning power similar to that of hand-rubbing. In addition, a bottom plate portion 19 inclined forward is disposed slightly below the surrounding wall portion 13 so that the cleaning liquid L flowing down through the bottom plate portion 19 can be discharged to the outside through the nozzle 20. It has become. A viewing window 51 through which the inside can be observed is formed on the front side of the box body 12. Furthermore, a heater (not shown) for heating the cleaning liquid L to about 40 to 55 ° C. may be provided in the cleaning box 11.

  As is clear from FIGS. 3 and 4, the upper surface cover 21 covers an abutment portion 23 that covers the upper surface opening 11 a of the cleaning box 11 so as to be freely opened and closed, and a motor 27 installed on the abutment portion 23. It is comprised by the cover main-body part 22 connected integrally with the abutment part 23 side. In the figure, reference numeral 52 denotes a hinge, 53 denotes a handle, and 54 denotes a fastener.

  Further, as is apparent from FIG. 1, a pair of hanging plates 24, 24 are suspended on the lower surface side of the abutment portion 23, and between these hanging plates 24, 24, a lid is attached. A pair of hard rolls 25 made of, for example, a synthetic resin material or a metal material such as duralumin, which is pressed by pushing the upper surface side in the length direction of the pair of elastic water-absorbing rolls 37, 37 about 2 mm apart from each other, 25 is arranged.

  The hard roll 25 is formed so that its outer diameter is smaller than the outer diameter of the elastic water-absorbing roll 37, and can thereby be brought into pressure contact while shifting the contact position with the elastic water-absorbing roll 37. .

  In addition, a large number of grooves 27 are engraved on the circumferential surface of the hard roll 26 in a direction intersecting or orthogonal to the rotation direction, and these grooves 27 are repeatedly pressed against the elastic water absorbing roll 37 side. It is possible to exert a cleaning power similar to that of hand-rubbing.

  Further, a drive gear 29 is fixed to the rotating shaft 28 of the motor 27, and a large-diameter gear 30 that is pivotally supported on the abutment portion 23 side is meshed with the drive gear 29. In this case, the large-diameter gear 30 is disposed under an arrangement relationship that meshes with the driven gear 40 included in the elastic water-absorbing roll 37 when the lid is applied.

  Further, the upper surface cover 21 is arranged so that it can be gently covered while supporting the weight by interposing the hydraulic upper 55 with the cleaning box 11.

  Next, the operation and effect of the present invention will be described based on the illustrated example. The front end guide portion 33 of the liquid removal unit 31 is provided in the vertical front groove portion 14 provided in the surrounding wall portion 13 in the cleaning box 11, and the vertical rear groove portion 15. The rear end guide part 34 is fed into the interior as shown in FIG.

  As shown in FIG. 3, the lowering surface 32a of the vertical plate 32 comes into contact with the liquid removal unit 31 that has been sent in to stop its movement, and is placed in the cleaning box 11 in this state. At this time, the elastic water absorption roll 38 provided in the liquid removal unit 31 is pressed into contact with the hard roll 17 and pushed in by about 2 mm.

When the liquid removal unit 31 is placed in the cleaning box 11 in this state, the cleaning liquid L reaches the predetermined liquid level height L _H in the box body 12 as is apparent from FIG. Supplied. In this case, if a heater (not shown) is provided in the cleaning box 11, the cleaning liquid L can be cleaned by heating to about 40 to 55 ° C. with a higher cleaning effect.

  After supplying the cleaning liquid L into the cleaning box 11, the upper surface cover 21 formed by integrating the cover main body portion 22 and the abutment portion 23 is pulled down to cover the upper surface opening 11a. At this time, since the upper surface cover 21 is supported by the hydraulic upper 55, even if it is relatively heavy, it can be gently covered while supporting it.

  After the lid is applied in this manner, the fastening state of the upper surface cover 21 with respect to the cleaning box 11 can be ensured by fastening the fastening device 54. Moreover, when the upper surface cover 21 is applied in this manner, each hard roll 25 is pressed against each elastic water-absorbing roll 37 and pushed in by about 2 mm as shown in FIG. At that time, the large-diameter gear 30 meshes with the driven gear 40 included in the elastic water absorption roll 37.

  After the preparation is completed in this way, the motor 27 is turned on to forcibly rotate the rotary shaft 28 and the drive gear 29. Since the large gear 30 is meshed with the drive gear 29, the driven gear 29 is driven to rotate, and the driven gear 40 meshed with the large diameter gear 30 is also rotated.

  In addition, since the driven gear 40 is coaxially connected to one elastic water-absorbing roll 37, the pair of elastic water-absorbing rolls 37, 37 rotate so as to be fed inward, and each hard roll included in the upper surface cover 21. 25 is also driven to rotate.

  At this time, since the outer diameter of the hard roll 25 is smaller than that of the elastic water-absorbing roll 37 and the groove 26 is provided, the hard roll 25 rotates while being pushed in by about 2 mm while shifting the pressure contact position with respect to the elastic water-absorbing roll 37. Therefore, the cleaning power similar to that of hand-washing can be exhibited in the cleaning liquid L.

  The driven gear 40 forcibly rotates the driven gear 41 via the idle gear 42, rotates one elastic water-absorbing roll 38 connected coaxially with the driven gear 41, and the other elastic water-absorbing roll 38. And the hard rolls 17 included in the cleaning box 11 are also driven to rotate.

  At this time, since the outer diameter of the hard roll 17 is smaller than that of the elastic water-absorbing roll 38 and the groove 18 is provided, the hard roll 17 rotates while being pushed in by about 2 mm while shifting the pressure contact position with respect to the elastic water-absorbing roll 38. Therefore, the cleaning power similar to that of hand-washing can be exhibited in the cleaning liquid L.

  Thus, after the cleaning is completed, the motor 27 is turned off to stop the movement, and then the fastening tool 54 is removed, the top cover 21 is opened, the liquid removal unit 31 is taken out, and the operation is completed. The cleaning liquid L can be smoothly discharged to the outside through the nozzle 20. Further, the motor 27 can be exposed by lifting the cover main body portion 22 through the upper hinge 52 by releasing the connection between the cover main body portion 22 and the abutment portion 23, so that the maintenance work is also possible. It can be done easily.

  The above is the description of the present invention based on the illustrated examples, and various modifications can be made to the specific contents without departing from the gist of the present invention. For example, the hard roll can be formed by making the outer diameter larger than that of the elastic water-absorbing roll, or by making it the same diameter depending on circumstances. Moreover, the groove | channel formed in the surrounding surface of a hard roll can also be formed by providing appropriate shapes other than the example of illustration which can exhibit the detergency similar to a hand-washing. Further, the cleaning box can be used without a heater.

  The present invention can be applied not only to the liquid removal unit provided in the coin cleaning device, but also to cleaning various elastic water absorbing rolls to which dirt adheres.
