Description

The present invention relates to a cleaning apparatus for corrugated plates used in breeding (cultivating) sea urchins, abalones, etc., more specifically, a corrugated plate cleaning device used to remove deposits adhering to the surface of corrugated plates. Regarding the device.

Conventionally, in this type of corrugated plate cleaning apparatus, a pair of feed rollers for sandwiching a breeding plate (corrugated plate) from both sides and feeding it between brush rollers consisted of a lower feed roller having a round peripheral surface and a softer roller. An aquatic organism rearing plate comprising upper feed rollers made of a material and having a flat peripheral surface, arranged so that the lower feed rollers contact the valleys of the corrugated plate and the upper feed rollers contact the crests of the corrugated plate. There is a cleaning device (see Patent Document 1, for example).
For the upper and lower brush rollers, linear bodies (brushes) are planted radially around the brush roller shaft. Two sets of four brushes are arranged in the feed direction of the corrugated sheet, and two electric motors rotate the upper and lower brushes in opposite directions. The pair of upper and lower feed rollers that are driven to rotate include a set of first feed rollers between the tray on the entrance side and the first brush roller, and a set of second feed rollers between the first brush roller and the second brush roller. Two sets of the third brush roller and the fourth brush roller are arranged between the set, the second brush roller and the shooter on the exit side, for a total of four sets of eight rollers. The upper and lower feed rollers are driven to rotate in the same direction as the upper and lower brushes by another electric motor. A sprinkler pipe for spraying water toward the brush roller is provided near the brush roller.
When the dirty corrugated sheet is pushed in from the tray, it is sandwiched between the first feed rollers and fed forward. Deposits such as moss adhering to both sides of the corrugated sheet are scraped off. The corrugated sheet that has passed between the first brush roller and the second brush roller and has become clean is discharged toward the shooter by the third and fourth feed rollers.

Registered Utility Model No. 3075418

By the way, in order to reliably remove deposits adhering to the corrugated plate by rotating the brush, it is necessary to scrape off the deposits by rotating the brush roller at a higher speed than the feeding speed of the corrugated plate by the feed roller.
However, in Patent Document 1, every time the corrugated plate is transferred from the feed roller to the brush roller on the downstream side, the brush comes into contact with the rear end surface of the corrugated plate in the advancing direction and pushes the corrugated plate in the feeding direction. There was a problem that the feeding speed became faster, and the cleaning by scraping off deposits due to the rotation of the brush became insufficient.
More specifically, the corrugated sheet fed by the first feed roller on the upstream side in the feed direction of the corrugated sheet is fed between the first brush rollers on the downstream side, and is fed by the second feed roller to the second brush roller. sent towards between After the corrugated plate is transferred between the second brush rollers from the first feed roller, when the rear end surface of the corrugated plate in the traveling direction passes between the first brush rollers by the feeding by the second feed roller, the first brush roller brushes directly hit against the rear end face of the corrugated plate. Since the rotational speed of the first brush roller is higher than the feed speed of the corrugated plate by the second feed roller, the brush of the first brush roller pushes the rear end face of the corrugated plate in the feed direction of the corrugated plate. Similarly, when the trailing end face of the corrugated plate passes between the second brush rollers by subsequent feeding by the third feed roller, the brush of the second brush roller directly abuts against and pushes the trailing end face of the corrugated plate.
As a result, the feeding speed of the corrugated plate is accelerated when it passes the brush roller, so there is a problem that the contact time with the brush is shortened and the detergency is lowered.
Therefore, it is conceivable to prevent acceleration of feeding of the corrugated sheet due to contact with the brush by strengthening the clamping force of the feed roller against the corrugated sheet. However, in this case, there is a problem that the portion of the corrugated sheet strongly pressed by the upper and lower feed rollers is deformed and damaged.
There is also a problem that the rear end face of the corrugated plate is damaged by the impact when the brush directly hits the rear end face of the corrugated plate due to the rotation of the brush roller.

In order to solve such problems, a corrugated plate cleaning device according to the present invention is a corrugated plate cleaning device for removing deposits adhering to a corrugated plate, wherein the corrugated plate is transferred along a transfer path. a feed mechanism provided, a brush roller having a brush rotatably provided in the middle of the transfer path, and facing the brush roller across the corrugated plate transferred by the feed mechanism in the middle of the transfer path. The rail has a convex portion that partially slides only on the valley portion of the corrugated plate being transferred by the feed mechanism, and the brush of the brush roller is provided with the brush As the roller rotates, it comes into contact with the convex portion, presses against the front surface or the back surface of the corrugated plate being transferred by the feed mechanism, and extends from the contact position with the convex portion toward the rear end surface of the corrugated plate in the traveling direction. It is characterized by having a hair tip portion that moves and abuts.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail based on the drawings.
As shown in FIGS. 1 to 5, a corrugated plate cleaning apparatus A according to an embodiment of the present invention is a cleaning device for removing deposits (not shown) adhering to a corrugated plate B during movement (transfer) of the corrugated plate B. machine.
The corrugated plate B is formed into a corrugated thin plate from an acrylic resin such as polycarbonate or a similar material. A plurality of parallel troughs Ba and crests Bb are alternately formed in the width direction of the corrugated sheet B on the front surface B1 and the back surface B2 of the corrugated sheet B. As shown in FIG.
When using the corrugated plate B for breeding (cultivating) sea urchins, abalone, etc., feed such as abalone and diatoms are added to the valleys Ba and peaks Bb of the front surface B1 and the back surface B2 of the corrugated plate B. Young sea urchins and juvenile abalone are attached to the oysters and grown in a breeding tank. When juvenile sea urchins, juvenile abalone, and the like grown on the corrugated plate B grow to a predetermined size, they are separated from the surface B1 and the back surface B2 of the corrugated plate B, and the breeding is switched to a net basket or basket.
After that, the corrugated sheet B is used for a long period of time, and excrement such as juvenile sea urchins and young abalone shells adheres and accumulates on the valleys Ba and peaks Bb of the front surface B1 and the back surface B2. This unwanted deposit is removed before being reused. For this reason, a cleaning machine is used to remove deposits adhering to the corrugated sheet B.

More specifically, a corrugated sheet cleaning apparatus A according to an embodiment of the present invention includes a feed mechanism 1 provided to transport a corrugated sheet B along a transfer path Bt, and a brush roller 2 provided in the middle of the transfer path Bt. and a rail 3 provided facing the brush roller 2 in the middle of the transfer path Bt as main components.
Furthermore, near the brush roller 2, as shown in FIGS. is preferably provided. The water sprinkling port 4 preferably consists of a nozzle or the like for injecting washing water.
In the corrugated plate cleaning apparatus A, the corrugated plate B is arranged such that the front surface B1 and the back surface B2 face in the vertical direction, and the thickness direction of the corrugated plate B is hereinafter referred to as the "Z direction". The width direction along the front surface B1 and the back surface B2 of the corrugated sheet B intersecting the Z direction is hereinafter referred to as the "X direction", and the length direction of the corrugated sheet B is hereinafter referred to as the "Y direction".

The feeding mechanism 1 is a conveying device that feeds the corrugated sheet B from one end to the other end of a long transfer path Bt in the length direction (Y direction). As the feed mechanism 1, it is preferable to use a roller feed mechanism in which the corrugated sheet B is fed by the rotation of the feed roller pressed against the corrugated sheet B and the frictional force.
In the case shown in FIGS. 1 to 4 as a specific example of the feed mechanism 1, it is composed of a pair of feed rollers arranged to sandwich the corrugated plate B in the thickness direction (Z direction), and one of the pair of feed rollers Alternatively, the corrugated plate B is sandwiched with a predetermined pressure by pressing the other or both of them toward the corrugated plate B with an elastic member 1a such as a spring. The corrugated sheet B is conveyed by rotating the pair of feed rollers in opposite directions while being linked by meshing or the like.
In the example shown in FIGS. 3A and 3B, only the upper feed roller facing the surface B1 of the corrugated sheet B is pressed by the elastic member 1a, and the outer peripheral surface of the upper feed roller is the surface of the corrugated sheet B. B1 and the outer peripheral surface of the lower feed roller facing the back surface B2 of the corrugated plate B is set to press against the back surface B2 of the corrugated plate B with approximately the same pressure.
Further, although not shown, other examples of the feed mechanism 1 may be modified such that only the lower feed roller is pressurized by the elastic member 1a, or the upper feed roller and the lower feed roller are each pressurized by the elastic member 1a. It is possible.

The brush roller 2 is a rotating body having a brush 2a made of a wire material such as nylon having appropriate hardness and elasticity on its outer peripheral surface, and is downstream of the feed mechanism 1 in the feed direction of the corrugated sheet B in the transfer path Bt. is rotatably supported in The rotation direction of the brush roller 2 is preferably set to be the same as the feeding direction of the corrugated sheet B by the feeding mechanism 1 (a pair of feeding rollers) so that the feeding speed of the corrugated sheet B by the feeding mechanism 1 is not reduced.
As shown in FIGS. 3(a)(b) to 5(a)(b), the brushes 2a of the brush roller 2 are of the same length so as to protrude radially from the axis of the brush roller 2 and form a cylindrical shape. The bristles are planted with a ridge and have a large number of bristle tips 2b.
A bristle tip portion 2b of the brush 2a abuts on a rail 3, which will be described later, and is arranged so as to be in pressure contact with the front surface B1 and the back surface B2 of the corrugated sheet B transferred along the transfer path Bt by the feed mechanism 1. FIG.
In other words, when the corrugated sheet B is not transferred to the brush roller 2 by the feeding mechanism 1 (when the corrugated sheet does not pass through), at least some of the many bristle tip portions 2b come into contact with the rails 3, which will be described later. After that, when the corrugated sheet B being transferred by the feeding mechanism 1 passes the brush roller 2 (passing the corrugated sheet), as shown in FIGS. All of them are in pressure contact with the front surface B1 and the back surface B2 of the corrugated plate B, and the rotational force of the brush roller 2 rubs off (scrapes off) deposits adhering to the front surface B1 and the back surface B2 of the corrugated plate B. For this reason, the rotation speed of the brush roller 2 is set to be higher than the feed speed of the corrugated plate B by the feed mechanism 1 (a pair of feed rollers) so as to reliably scrape off the deposits.

The rail 3 is a fixed body linearly elongated in the direction (Y direction) in which the corrugated sheet B is transferred by the feed mechanism 1. The brush roller 2 and the corrugated plate B are arranged so as to face each other in the thickness direction (Z direction) with the transferred corrugated plate B interposed therebetween. The rail 3 has a protrusion 3a protruding toward the brush roller 2 and part of the corrugated plate B. As shown in FIG.
As shown in FIGS. 5(a) and 5(b), the convex portion 3a of the rail 3 is formed only partially and partially in the width direction (X direction) among the many bristle tip portions 2b of the brush 2a of the brush roller 2. and a part of the front surface B1 and the back surface B2 of the corrugated plate B in the width direction (X direction).
More specifically, when the corrugated plate B is not transferred to the brush roller 2 and does not pass through the corrugated plate, only part of the bristle tip 2b of the brush 2a abuts against the protrusion 3a, and part of the bristle tip 2b is elastically deformed. configured to allow As a result, part of the hair tip portion 2b is spread in the width direction (X direction) along the convex portion 3a.
After that, when the corrugated sheet B passes through the brush roller 2 by the feed mechanism 1, only the troughs Ba formed on the front surface B1 and the back surface B2 of the corrugated sheet B move in the thickness direction (Z direction) along with the convex portions 3a. The corrugated sheet B is fitted to the feed mechanism 1 so as to be slidably contacted in the transport direction (Y direction).
Subsequently, after the corrugated sheet B has been transferred from the feeding mechanism 1 to between the brush roller 2 and the rail 3, the corrugated sheet B passes the brush roller 2 as shown in FIGS. At this time, the bristles 2b of the brush 2a abut against the rear end surface B3 of the corrugated plate B in the traveling direction.

On the other hand, when the rail 3 is not provided as in Patent Document 1, immediately after the corrugated plate B is transferred from the feed mechanism 1 to the brush roller 2 and passed through the brush roller 2, all the bristles 2b of the brush 2a are It abuts directly against the rear end face B3 of the corrugated plate B in the traveling direction.
Here, the rotating direction of the brush roller 2 is the same as the feeding direction of the corrugated sheet B by the feeding mechanism 1 (a pair of feeding rollers), and the rotational speed of the brush roller 2 is higher than the feeding speed of the corrugated sheet B by the feeding mechanism 1. If it is set too fast, the bristle tip portion 2b of the brush 2a of the brush roller 2 pushes the rear end face B3 of the corrugated sheet B in the feeding direction.
As a result, the feed speed of the corrugated plate B is accelerated when the corrugated plate B passes the feed speed, shortening the contact time with the bristle tip portion 2b and degrading the detergency.
In addition, due to the rotation of the brush roller 2, the bristle tip portion 2b of the brush 2a may directly hit against the advancing direction rear end surface B3 of the corrugated plate B, and the impact may damage the advancing direction rear end surface B3 of the corrugated plate B. There was also

On the other hand, in the corrugated plate cleaning apparatus A according to the embodiment of the present invention, the rail 3 is provided. It is configured to move from the contact position with the convex portion 3a toward the rear end face B3 of the corrugated plate B in the advancing direction. At least some of the many hair tip portions 2b come into contact with the convex portion 3a of the rail 3 and are spread in the width direction (X direction) along the convex portion 3a. Therefore, a frictional force (sliding friction) is generated between the tip portion 2b and the convex portion 3a that are in contact with the convex portion 3a.
That is, as shown in FIGS. 5A and 5B, immediately after the corrugated plate B passes the brush roller 2, the brush 2a is pushed against the convex portion 3a of the rail 3 exposed by the passage of the corrugated plate B. Since the bristle tip 2b abuts against the traveling direction rear end surface B3 of the corrugated plate B after contact, the frictional force (sliding friction) generated by the contact between the bristle tip 2b and the convex portion 3a causes the bristle tip to move. At the same time as the movement speed of the bristles 2b slows down, the momentum of the bristle tips 2b toward the traveling direction rear end face B3 of the corrugated plate B is attenuated, and the pressing force of the bristle tips 2b against the traveling direction rear end face B3 of the corrugated plate B decreases. do.
As a result, even if the rotation speed of the brush roller 2 is faster than the feeding speed of the corrugated plate B by the feed mechanism 1, the pressing force by the bristle tip portion 2b of the brush 2a is less likely to be transmitted to the rear end surface B3 of the corrugated plate B in the advancing direction. , the feed speed of the corrugated sheet B is not accelerated and does not change when the feed speed of the corrugated sheet B passes.

By the way, as a method for enhancing the guiding function of the corrugated sheet B, instead of the rail 3 described above, a guide plate (not shown) having an uneven surface that faces and fits the entire valley Ba and crest Bb of the corrugated sheet B is provided. is provided, and when the corrugated sheet B transferred by the feed mechanism 1 passes, the uneven surface of the guide plate can be brought into contact with the entirety of the valleys Ba and crests Bb of the corrugated sheet B. is.
However, when the entire troughs Ba and ridges Bb of the corrugated sheet B are brought into surface contact with the uneven surface of the guide plate, the interfaces between the two come into close contact with each other, and the feed mechanism 1 (the rotation of the pair of feed rollers There is a problem that even if the corrugated sheet B is fed by driving, the corrugated sheet B cannot be moved with respect to the uneven surface of the guide plate.
In particular, when the washing water is supplied from the water sprinkling port 4 toward between the front surface B1 or the rear surface B2 of the corrugated plate B and the brush roller 2, the entire valley Ba and crest Bb of the corrugated plate B and the guide plate The cleaning water enters the gap between the corrugated sheet B and the uneven surface of the corrugated sheet B, making it easier for the interfaces between the two to come into close contact with each other.

Therefore, in order to solve such a problem, instead of a guide plate having an uneven surface that makes surface contact with the entire trough Ba and ridge Bb of the corrugated sheet B, only the trough Ba of the corrugated sheet B is partially formed. A rail 3 having a convex portion 3a abutting on is provided. As a result, the rail 3 does not abut against the crests Bb of the corrugated sheet B, and even if the cleaning water enters the gaps between the protruding portions 3a of the rails 3 and the troughs Ba of the corrugated sheet B, the corrugated sheet B is The entire valley Ba and peak Bb and the interface between the rail 3 do not come into close contact with each other.
In particular, the rail 3 is composed of a plurality of rod-shaped bodies 3r, and the plurality of rod-shaped bodies 3r are arranged at predetermined intervals in the width direction (X direction) intersecting the transfer path Bt, that is, the direction in which the corrugated sheet B is transferred by the feed mechanism 1. preferably. When the rail 3 is composed of a plurality of rod-shaped bodies 3r, the plurality of rod-shaped bodies 3r are integrated by attaching the plurality of rod-shaped bodies 3r to the holding member 3s at predetermined intervals in the X direction. Placement is fixed.
Furthermore, it is preferable that the plurality of rod-shaped bodies 3r that form the rails 3 have mounting surfaces 3b on the side opposite to the projections 3a, and that the mounting surfaces 3b are mounted in surface contact with the front surface of the holding member 3s.
In the illustrated example, the mounting surface 3b of each rod-shaped body 3r and the front surface of the holding member 3s facing the mounting surface 3b are each formed smooth, and each rod-shaped body 3r is mounted on the front surface of the holding member 3s. The surfaces 3b are detachably fixed by temporary fixing means 3t such as screws while the surfaces 3b are in surface contact with each other. In addition, the front surface of the holding member 3s is installed in a non-contact state with the ridges Bb of the corrugated sheet B so as to face the ridges Bb with a gap therebetween.
Further, tip portions 3c on the upstream side in the direction in which the corrugated sheet B is transported by the feed mechanism 1 in the plurality of rod-shaped bodies 3r forming the rails 3 are formed so as to gradually taper toward the tips. Therefore, the forward end portion B4 of the corrugated sheet B transferred by the feeding mechanism 1 can be smoothly transferred to the plurality of rod-shaped bodies 3r that form the rails 3. As shown in FIG.

Next, a specific example of the corrugated plate cleaning apparatus A according to the embodiment of the present invention will be described.
In the case shown in FIGS. 1 to 5 (a) to 5 (a) and (b), a corrugated plate B 4 sets of 8 pairs of feed rollers, 4 sets of brush rollers 2, and 4 sets of 9 pieces each of a plurality of rod-shaped bodies 3r that form rails 3 are arranged along the transfer path Bt. . More specifically, a pair of first feed rollers 11 are arranged at the upstream end of the transfer path Bt, and on the downstream side thereof, an upper first brush roller 21 and a lower first rail 31, a lower second brush roller 22 and An upper second rail 32 is arranged. Downstream thereof, a pair of second feed rollers 12 are arranged, and downstream therefrom a third upper brush roller 23 and a third lower rail 33, a fourth lower brush roller 24 and a fourth upper rail. 34 are placed. A pair of third feed rollers 13 and a pair of fourth feed rollers 14 are arranged at the downstream end of the transfer path Bt.
In the illustrated example, all of the pair of feed rollers are linked to a feed drive source 1d such as a motor via a feed transmission component 1t such as a chain. All the brush rollers 2 are linked to a brush drive source 2d such as a motor through a brush transmission component 2t such as a belt.
As another example, although not shown, it is possible to change the number and arrangement of the pair of feed rollers, the brush rollers 2, and the rails 3, which constitute the feed mechanism 1, to those other than the illustrated example.

Further, the nozzles serving as the washing water sprinkling ports 4 are directed between the second lower brush roller 22 and the upper second rail 32 and between the lower fourth brush roller 24 and the upper fourth rail 34. placed respectively.
A holding member 3s, to which smooth mounting surfaces 3b of a plurality of rod-shaped bodies 3r that serve as rails 3 are detachably fixed, is mounted to a frame A2 within a housing A1.
Outside the housing A1, a carrying-in table A3 leading to the upstream end of the transfer path Bt and a carrying-out table A4 leading to the downstream end of the transferring path Bt are respectively protruded. A plurality of carry-in guides 5 are provided to abut on the trough Ba of the rear surface B2 of B. As shown in FIG.
The housing A1 has an open top surface and is covered with a cover A5 so as to be openable and closable.
As another example, although not shown, the sprinkling port 4, the frame A2, the carrying-in table A3, the carrying-out table A4, the carrying-in guide 5, the cover A5, etc. can be changed to structures other than those shown.

According to the corrugated plate cleaning apparatus A according to the embodiment of the present invention, the corrugated plate B is moved along the transfer path Bt by the brush roller 2 (first brush roller 11) by the operation of the feed mechanism 1 (first feed roller 11). 21). Therefore, the corrugated sheet B enters between the brush roller 2 and the rail 3 (the first rail 31), and only the trough Ba of the corrugated sheet B (the front surface B1 or the rear surface B2 of the corrugated sheet B) becomes the convex portion 3a of the rail 3. and partially abut (sliding). Next, the bristles 2b of the brush 2a are brought into pressure contact with the back surface B2 or the surface B1 of the corrugated plate B by the rotation of the brush roller 2, and the sediment adhering to the back surface B2 or the surface B1 of the corrugated plate B is washed and removed. do.
Subsequently, when the corrugated sheet B passes through the brush roller 2, the bristle tip 2b of the brush 2a comes into contact with the convex portion 3a of the rail 3 to generate a frictional force (sliding friction) therebetween. Since the bristle tip portion 2b abuts against the advancing direction rear end surface B3 of the corrugated plate B, the moving speed of the bristle tip portion 2b is reduced, and the pressing force of the bristle tip portion 2b against the advancing direction rear end surface B3 of the corrugated plate B is reduced.
As a result, even if the rotation speed of the brush roller 2 is faster than the transfer speed of the corrugated sheet B by the feed mechanism 1, the transfer speed of the corrugated sheet B does not change.
Therefore, the feed acceleration of the corrugated sheet B due to the rotation of the brush 2a can be prevented.
As a result, every time the corrugated plate is transferred from the feed roller to the brush roller, the brush directly strikes against and pushes the rear end surface of the corrugated plate in the advancing direction, and the brush for the front surface B1 or the back surface B2 of the corrugated plate B is reduced. The contact time of the bristles 2b of the bristles 2a is not shortened, and deposits adhering to the surface B1 or the back surface B2 of the corrugated plate B can be reliably removed by the rotation of the brush 2a.
Also, the impact when the bristle tip 2b of the brush 2a hits the rear end surface B3 of the corrugated plate B in the traveling direction due to the rotation of the brush roller 2 is the frictional force (slip Therefore, even if the rotational speed of the brush roller 2 is increased, the rear end surface B3 of the corrugated plate B in the advancing direction is not damaged, and the detergency and safety can be improved.
Furthermore, when a roller feed mechanism in which the corrugated sheet B is fed by the rotation of the feed roller in pressure contact with the corrugated sheet B and the frictional force is used as the feed mechanism 1, the pressing force (clamping force) of the feed roller against the corrugated sheet B is , there is no need to prevent the feed acceleration of the corrugated sheet B due to the rotation of the brush 2a, so deformation and breakage of the corrugated sheet B can also be prevented.
In addition to this, only the troughs Ba of the corrugated sheet B (the front surface B1 or the rear surface B2 thereof) transferred by the feed mechanism 1 partially abut (sliding) the convex portions 3a of the rails 3. The peaks Bb of (the front surface B1 or the rear surface B2 of) the corrugated plate B do not contact the rails 3 . For this reason, the entire corrugated plate B (the front surface B1 or the rear surface B2 thereof) does not come into surface contact with the rail 3, and even if water enters between the corrugated plate B and the rail 3, the interfaces between the two are brought into close contact with each other. , the corrugated plate B can be prevented from becoming immovable. As a result, the cleaning of the corrugated sheet B is not interrupted, and the operation is excellent in stability.

In particular, the rail 3 preferably consists of a plurality of rod-shaped bodies 3r arranged in the width direction (X direction) intersecting the transfer path Bt.
In this case, even if the interval between the troughs Ba and the ridges Bb is changed by changing the shape of the corrugated sheet B, the troughs of the corrugated sheet B whose shape has been changed can be adjusted by adjusting the arrangement intervals of the plurality of rod-shaped bodies 3r. Facing Ba, the projections 3a of the plurality of rod-shaped bodies 3r can come into contact (sliding contact) with each other.
Therefore, the position of the rail 3 can be adjusted according to the shape change of the corrugated sheet B.
As a result, it is possible to easily adapt to a change in the shape of the corrugated sheet B, and it is convenient without the need for labor.
Furthermore, since there is no need to manage inventory of a plurality of types of rails 3 according to the type of corrugated sheet B whose shape has been changed, inventory management is easy and cost can be reduced.

Furthermore, it is preferable that the rail 3 has a mounting surface 3b on the side opposite to the convex portion 3a, and the mounting surface 3b is mounted in surface contact with the holding member 3s.
In this case, the mounting surface 3b of the rail 3 and the front surface of the holding member 3s are formed smooth, respectively, so that the rail 3 can be attached to the front surface of the holding member 3s so that they are in surface contact with each other. The mounting surface 3b of is positioned without rattling.
Therefore, the rail 3 can be reliably fixed and arranged.
As a result, even if vibration occurs when deposits adhering to the front surface B1 or the back surface B2 of the corrugated sheet B are removed by the bristle tip portion 2b of the brush 2a due to the rotation of the brush roller 2, the front surface of the holding member 3s is removed. The mounting surface 3b of the rail 3 is not displaced, and the stability of the cleaning work is excellent.

In the illustrated example of the above-described embodiment, the cross-sectional shape of the corrugated plate B is a corrugated curved surface. A corrugated shape or the like that is bent into a shape may be used.
Furthermore, although the case where the feed mechanism 1 is composed of a pair of feed rollers arranged to sandwich the corrugated sheet B in the thickness direction (Z direction) has been shown, the present invention is not limited to this, and a conveying device other than the feed rollers may be used. good.
In the illustrated example, the mounting surfaces 3b of the plurality of rod-shaped bodies 3r that form the rails 3 are mounted in surface contact with the front surface of the holding member 3s. 3r and holding member 3s may be integrally formed. In this case as well, the portion corresponding to the front surface of the holding member 3s faces the ridges Bb of the corrugated sheet B with a gap therebetween, and is installed in a non-contact state with the ridges Bb.
