[0034]
6 to 9 show a state in which the washing device 1 for a dehydrator is disposed in the laver dehydrator 6. FIG. 6 is a front view, FIG. 7 is a right side view of FIG. 6, and FIG. 8 shows a state where washing of the dewatering sponge 72 has been completed and the dehydrator cleaning device 1 has been retracted. 9 shows a right side view of FIG.
[0035]
First, before describing the operation of the washing device 1 for a dehydrator, the configuration of the laver dehydrator 6 shown in the present embodiment will be described.
[0036]
This laver dewatering machine 6 is provided with six sets of an upper dewatering sponge 72a and a lower dewatering sponge 72b in two rows. Each dewatering sponge 72 is held on a fixed plate 76 by a leaf spring or the like, similarly to the conventional one. The fixing plate 76 of the lower dehydrating sponge 72b is fixed to a suction housing 78 for dehydrating the paper laver 75, and the fixing plate 76 of the upper dehydrating sponge 72a is fixed to the upper part of the laver dehydrator 6. . The laver dehydrator 6 is supported by a dehydrator support member 61 at both left and right end positions in FIG. 6, and the elevating shaft 62 is vertically disposed on the dehydrator support member 61. Further, a hydraulic pressure source (not shown) is housed inside the dehydrator support member 61, and the lifting shaft 62 moves up and down by this hydraulic pressure. The upper part of the elevating shaft 62 and the upper part of the main body of the laver dehydrator 6 are connected. For this reason, the upper dehydrating sponge 72a can be moved up and down along the elevating shaft 62, and when the paper laver 75 is dewatered, it descends and holds the paper laver 75 together with the lower dewatering sponge 72b.
[0037]
In contrast to such a laver dehydrator 6, the dehydrator cleaning device 1 of the present embodiment has the cleaning drive unit 3 disposed at an intermediate position between two rows of the dehydrating sponge 72. On the other hand, the main body fixing member 20 of the main body support portion 2 is fixed on the left side surface of the laver dehydrator 6 in FIG.
[0038]
When the dewatering sponge 72 is to be cleaned, the cleaning unit supporting arm 30 of the cleaning driving unit 3 is supported so as to maintain the horizontal position, and the cleaning roller 40 of the cleaning unit 4 is moved to the upper dewatering sponge 72a and It is arranged between the lower dewatering sponge 72b. At this time, the upper dewatering sponge 72a of the laver dewatering machine 6 descends, and sandwiches the cleaning roller 40 together with the lower dewatering sponge 72b. From this state, the drive motor 36 disposed in the main body support arm 22 is driven to rotate the pair of sprockets 32, 32 to thereby drive the drive chain 31 wound around the sprocket 32 in FIG. Rotate clockwise. When the drive chain 31 rotates, the connecting member 42 attached to the drive chain 31 also follows, and moves along the guide shaft 34 to the left in FIG. With the movement of the connecting member 42, the roller support 41 of the cleaning unit 4 fixed thereto and the cleaning roller 40 mounted on the roller support shaft 41c of the roller support 41 move. Since the cleaning roller 40 is rotatably mounted on the roller support shaft 41c via a bearing, when the cleaning roller 40 moves between the upper and lower dehydrating sponges 72, the cleaning roller 40 rotates by the frictional force with the dehydrating sponge 72. It will move while moving. When the cleaning roller 40 moves, cleaning water is supplied from a water supply pipe 50 attached to the cleaning roller 40. For this reason, the washing roller 40 moves the upper dehydrating sponge 72a and the lower dehydrating sponge 72b containing water by water supply in a squeezed manner, and automatically cleans each dehydrating sponge 72.
[0039]
When the cleaning roller 40 makes one reciprocation to the left and right in FIG. 6, one cycle of cleaning is completed. The cleaning cycle will be determined according to the degree of contamination of the dewatering sponge 72.
[0040]
Then, when the washing of the dehydrating sponge 72 of the laver dehydrator 6 is completed and the dehydration of the paper laver 75 is started by the laver dehydrator 6, the washing roller 40 is removed as shown in FIGS. 8, is moved out of the dehydrating sponge 72 at the right end of FIG. 8 and is removed from between the upper and lower dehydrating sponges 72, and the washing device 1 for the dehydrator is rotated about the main body rotating shaft 21 of the main body support 2. 8 to rotate the dehydrator cleaning device 1 to the retracted position. By retracting the dehydrator washing device 1 in this way, the upper dehydrating sponge 72a can be smoothly lifted and lowered, and the laver dehydrator 6 can dehydrate the paper laver 75.
[0041]
Therefore, according to the embodiment of the present invention, since the dewatering sponge 72 can be automatically cleaned while being attached to the laver dehydrator 6, the dewatering sponge 72 can be easily and efficiently cleaned.
[0042]
Further, since the washing of the dehydrating sponge 72 is facilitated, dirt of the dehydrating sponge 72 can be frequently removed, thereby improving hygiene and improving the drying efficiency of the paper laver 75. Thus, the life of the dewatering sponge 72 is extended.
[0043]
It should be noted that the present invention is not limited to the above-described embodiment, but can be variously modified as needed.
[0044]
For example, although the cleaning roller 40 is configured to move in the longitudinal direction of the laver dewatering machine 6, the cleaning roller 40 may be configured to change the moving direction by 90 degrees with respect to the longitudinal direction and move in the lateral direction.
[0045]
Further, the driving range of the cleaning unit 4 by the cleaning driving unit 3 may be changed according to the number of sets of the dewatering sponges 72 provided in the laver dewatering machine 6.
[0046]
【The invention's effect】
As described above, according to the cleaning device for a dehydrator according to the present invention, since the dehydrating sponge can be automatically cleaned while being attached to the laver dehydrator, the dehydrating sponge can be easily and efficiently cleaned.
[0047]
Further, since the washing of the dehydrating sponge is facilitated, dirt of the dehydrating sponge can be frequently removed to improve hygiene, and the drying efficiency of the paper laver can be increased. This has the effect of extending the life of the sponge.
