Description

  The present invention relates to a sponge plate washing machine for cleaning a sponge plate such as a sponge plate for dewatering fresh seaweed mounted on a press dewatering unit of a dry seaweed production apparatus for dewatering fresh seaweed made on a laver cocoon, for example. .

  In general, dry laver production equipment is used to dry paper laver thinly on a laver, a dehydration part that dehydrates fresh seaweed that has been laid on the seam, and dry raw laver dehydrated in the dewatering part. The dehydration unit is configured to press the raw laver dehydrated sponge plate from above and below to the laver that is made of fresh laver and press dehydrate the fresh laver. The sponge plate for dewatering raw laver used for this press dehydration is because the debris of raw laver strongly adheres to the sponge plate by repeating dehydration of the raw laver, and the dehydration ability of the sponge plate is reduced and various bacteria are generated. It is necessary to wash the board from time to time with a sponge board washing machine or the like.

Conventionally, as this kind of sponge plate washing machine, what is shown in patent documents 1-3 is known.
In Patent Document 1, an upper roller group in which a large number of rotatable rollers are arranged in parallel in the horizontal direction at intervals of about one-third of the length of the sponge plate in the conveying direction, and the lower rollers are opposed to each other. A lower roller group in which a large number of rotatable rollers are juxtaposed in the horizontal direction, and a cleaning nozzle for injecting cleaning water onto a sponge plate transferred between one roller group and the other roller group, The other roller is formed in a cylindrical shape with a large number of through holes, and one roller is formed with no through holes, and cleaning water is radiated to the lower surface of the sponge plate by the cleaning nozzle and washed. The sponge plate that has absorbed water is compressed by the upper roller and the lower roller, and the washing water is squeezed downward to wash the sponge plate.
In Patent Documents 2 and 3, the feed roller pair, the squeeze roller pair, the squeeze roller pair, and the feed roller pair that are rotatable in the cleaning tank are approximately the same as or shorter than the length in the conveyance direction of the sponge plate by a predetermined amount. In parallel with each other at an interval, a rubbing blade is rotatably provided between the squeezing roller and the squeezing roller and between the squeezing roller and the feeding roller, and a water pipe for discharging water on the upper surface of the sponge plate is provided. The sponge plate is discharged to the sponge plate while being conveyed by each roller pair, the sponge plate is squeezed by the pair of squeezing rollers, and the front and back surfaces of the sponge plate are rubbed and washed by the rubbing blades.

  However, in Patent Document 1, a large number of rollers in the upper roller group and a large number of rollers in the lower roller group are arranged in parallel with an interval of about one third of the length in the conveyance direction of the sponge plate. Therefore, when the sponge plate is sandwiched and transported between the upper roller group and the lower roller group, 1 to 3 portions in the transport direction length of the sponge plate are always strongly sandwiched by the roller pair. For this reason, if the sponge plate is skewed and supplied between the roller pair, the sponge plate is accompanied by the sandwiching and conveying of the sponge plate due to the difference in resistance between the left and right when the sponge plate is sandwiched and conveyed between the roller pair. There is a problem that the distortion of the sponge plate becomes large, and the sponge plate is washed, and sometimes the sponge plate is damaged.

Further, in Patent Documents 2 and 3, each roller pair is arranged in parallel with a gap that is substantially equal to or shorter than the length of the sponge plate in the conveyance direction, so that the sponge plate is sandwiched between each roller pair. When transporting, one portion of the sponge plate in the transport direction is always strongly held by the roller pair. Therefore, as in the case of Patent Document 1, when the sponge plate is obliquely distorted and supplied between the roller pair, a difference occurs in the left and right resistance when the sponge plate is nipped and conveyed between the roller pair. As the sponge plate is nipped and conveyed, the distortion of the sponge plate is increased, and there is a problem that the sponge plate is washed and sometimes damaged.
Therefore, the problem of the present invention is that when the sponge plate is nipped and conveyed between the roller pair, the sponge plate is conveyed while the sponge plate is being conveyed even if the sponge plate is skewed and supplied between the roller pair. A sponge plate washer that can correct the posture so that the front edge of the sponge plate is in a direction perpendicular to the conveyance direction, can convey the sponge plate straight and can be cleaned reliably, and can prevent damage to the sponge plate It is to provide.

In order to solve the above problems, the present invention is provided with a pair of squeezing rollers capable of sandwiching and conveying a sponge plate and a water discharge pipe capable of discharging water between the pair of squeezing rollers. In a sponge plate washer that discharges and cleans the sponge plate that is conveyed, a supply-side squeezing roller pair that can rotate forward and reverse, a discharge-side squeezing roller pair that can rotate forward and reverse, and a supply-side squeezing roller pair A pair of feed rollers capable of rotating in the forward and reverse directions between the pair of discharge-side squeezing rollers, and the outer shape of the upper roller of the pair of feed rollers is gradually smaller than the thickness of both ends. to a large drum shape, the distance of the discharge-side throttle rollers and the supply-side throttle roller pair larger than the conveying direction length of the sponge plate, between the supply side throttle roller pair and the feed rollers and the discharge side throttle rollers and the feed rollers A distance smaller than the conveying direction length of each sponge plate, the gap between the upper and lower rollers of the pair of feed rollers slightly smaller than the thickness of the sponge plate to contact the sponge plate, sponge plate that is sending at a feed roller pair Is configured to reach the squeezing roller pair on the supply side or the discharge side. (Claim 1)

Further, the present invention is characterized in that the upper side roller and the lower side roller of the supply side squeeze roller pair and the discharge side squeeze roller pair are formed of a perforated roller having a cylindrical shape and a large number of through holes on the outer periphery. (Claim 2 )
In addition, the present invention is configured such that when the discharge-side squeezing roller pair rotates forward and sandwiches and conveys the sponge plate and is conveyed more than half the length of the sponge plate in the conveyance direction, this is detected by a photoelectric switch and the discharge-side restrictor is detected. When the roller pair, the feed roller pair, and the supply side squeeze roller pair are reversed, and the supply side squeeze roller pair is reversed, the sponge plate is nipped and conveyed to convey more than half the length of the sponge plate in the conveyance direction. It is characterized by comprising a control device that detects with a photoelectric switch and rotates the supply side squeeze roller pair, the feed roller pair, and the discharge side squeeze roller pair in the normal direction. (Claim 3 )

The present invention relates to a feed-side squeezing roller pair capable of forward / reverse rotation, a discharge-side squeezing roller pair capable of forward / reverse rotation, and a feed capable of forward / reverse rotation positioned between the supply-side squeezing roller pair and the discharge-side squeezing roller pair. A pair of rollers, the distance between the supply-side squeezing roller pair and the discharge-side squeezing roller pair is larger than the length of the sponge plate in the conveying direction, and between the supply-side squeezing roller pair and the feeding roller pair and between the discharge-side squeezing roller pair and the feeding roller pair. The distance between each is made smaller than the length of the sponge plate in the conveyance direction, and the gap between the upper and lower rollers of the feed roller pair is made slightly smaller than the thickness of the sponge plate so as to make weak contact with the sponge plate, and the feed roller pair feeds. Since the sponge plate reaches the pair of squeezing rollers on the supply side or the discharge side, even when the sponge plate is skewed and supplied between the pair of rollers, the sponge plate is still being transported. Conveying posture can the correct as the leading edge of the sponge plate is in a direction perpendicular to the conveying direction, it is possible reliably cleaned by straight conveying the sponge plate, an effect of preventing damage to the sponge plate.
Further, according to the present invention, the outer shape of the upper roller of the pair of feed rollers is formed into a drum shape in which the thickness of the intermediate portion in the length direction is gradually larger than the thickness of both end portions. It is easy to change the direction to the left and right around the center part of the sponge, and when the tip of the sponge plate contacts the supply-side squeezing roller pair or the discharge-side squeezing roller pair, the tip becomes the supply-side squeezing roller pair or the discharge-side squeezing The posture is smoothly and easily corrected along the axis of the roller pair.
Further, in the present invention, the upper roller and the lower roller of the supply-side squeezing roller pair and the discharge-side squeezing roller pair are formed of a perforated roller having a cylindrical shape and a large number of through holes on the outer periphery. When sandwiched and transported by the pair of side squeezing rollers or the pair of discharge side squeezing rollers, the surface of the sponge plate will sink into the through hole of the perforated roller and be rubbed, so that the surface of the sponge plate can be cleaned cleanly and the sponge plate can be sandwiched. It has an advantage that the sponge plate can be cleaned cleanly by efficiently discharging the dirty water contained in the sponge plate through the through-holes during transport.
In addition, the present invention is configured such that when the discharge-side squeezing roller pair rotates forward and sandwiches and conveys the sponge plate and is conveyed more than half the length of the sponge plate in the conveyance direction, this is detected by a photoelectric switch and the discharge-side restrictor is detected. When the roller pair, the feed roller pair, and the supply side squeeze roller pair are reversed, and the supply side squeeze roller pair is reversed, the sponge plate is nipped and conveyed to convey more than half the length of the sponge plate in the conveyance direction. Since it has a control device that detects the photoelectric switch and rotates the supply-side squeeze roller pair, the feed roller pair, and the discharge-side squeeze roller pair in the normal direction, the sponge plate can be moved back and forth accurately to ensure automatic cleaning. .

You may make it roll.

  Next, the operation of the sponge plate washer will be described. First, the sponge plate 5 is mechanically supplied between the supply-side squeezing roller pair 6 by the sponge plate automatic supply device 35. The supply of the sponge plate 5 is performed, for example, when a transfer member (not shown) pushes and moves the sponge plate 5 moved to the supply position by the automatic sponge plate supply device 35 toward the supply-side squeezing roller pair 6. Simultaneously with the supply of the sponge plate 5, the drive motor 26 operates to rotate the supply-side squeeze roller pair 6, the discharge-side squeeze roller pair 7 and the feed roller pair 8 in the direction of nipping and conveying in the discharge side direction. Further, water is supplied to the water discharge pipes 23 and 24, and water is discharged downward from the water discharge holes of the water discharge pipes 23 and 24. The driving motor 26 may be driven in advance by a start switch.

  As a result, the sponge plate 5 is nipped and conveyed by the supply-side squeezing roller pair 6 and then conveyed to the discharge-side squeezing roller pair 7 by the post-feed roller pair 8, and is nipped and conveyed to the discharge side by the discharge-side squeezing roller pair 7. The At this time, the lower surface of the sponge plate 5 is supported by the support pieces 20 and 21, and the left and right side surfaces are guided by the guide plates 20A and 21A as necessary. When the sponge plate 5 is conveyed by the discharge-side squeezing roller pair 7 by about two-thirds, which is more than half of the length in the conveyance direction, the position of the sponge plate 5 is detected by a photoelectric switch and driven by the detection signal. The rotation direction (forward rotation) of the motor 26 is reversed (or the clutch may be switched by interposing a reversing mechanism having a clutch (not shown) in the middle), and the supply-side squeezing roller pair 6 and the discharge-side squeezing roller. The pair 7 and the feed roller pair 8 are reversed. As a result, the sponge plate 5 is nipped and conveyed by the discharge-side squeezing roller pair 7 and then conveyed to the supply-side squeezing roller pair 6 by the feed roller pair 8 and is nipped and conveyed to the supply side by the supply-side squeezing roller pair 6. The When the sponge plate 5 is conveyed by the supply-side squeezing roller pair 6 by about two-thirds of the length in the conveyance direction, the photoelectric switch detects the position of the sponge plate 5, and the supply-side squeezing roller is detected by the detection signal. The reverse rotation of the pair 6, the discharge-side squeezing roller pair 7 and the feed roller pair 8 is switched to the normal rotation, and the sponge plate 5 is nipped and conveyed again in the discharge-side direction.

This drainage is received by the bottom wall 3 of the cleaning space 4 and collected in a tank (not shown).

  As described above, when the sponge plate 5 is reciprocally conveyed by the supply side squeeze roller pair 6, the feed roller pair 8, and the discharge side squeeze roller pair 7 to clean the sponge plate 5, the sponge plate 5 is supplied to the supply side squeeze roller pair. 6 and the discharge-side squeezing roller pair 7 so that the sponge plate 5 is conveyed in a distorted state as shown in FIG. 3 when the sponge plate 5 is distorted and held in a posture (orientation). Will be. However, since the distance in the conveying direction between the supply-side squeezing roller pair 6 and the discharge-side squeezing roller pair 7 is set to be a predetermined amount larger than the length in the conveying direction of the sponge plate 5, the sponge plate 5 is discharged from the supply-side squeezing roller pair 6. The side squeezing roller pair 7 is not sandwiched between the supply side squeezing roller pair 6 and the discharge side squeezing roller pair 7. In addition, the distance between the supply-side squeeze roller pair 6 and the feed roller pair 8 and the distance between the discharge-side squeeze roller pair 7 and the feed roller pair 8 are set to be smaller than the length of the sponge plate 5 in the conveying direction. As shown in FIG. 4, in the state where it is not sandwiched between the side squeezing roller pair 6 and the discharge side squeezing roller pair 7, the leading end of the sponge plate 5 conveyed by the feed roller pair 8 is on the supply side. It reaches and contacts the squeezing roller pair 6 or the discharge-side squeezing roller pair 7. When the tip of the sponge plate 5 reaches the supply-side squeezing roller pair 6 or the discharge-side squeezing roller pair 7, the tip of the sponge plate 5 comes into contact with the supply-side squeezing roller pair 6 or the discharge-side squeezing roller pair 7. It is conveyed by the feed roller pair 8 along the roller pair direction, and the posture of the sponge plate 5 is corrected. The sponge plate 5 whose posture is corrected is caught in the supply-side squeezing roller pair 6 or the discharge-side squeezing roller pair 7 and is conveyed by being sandwiched, and the cleaning operation is performed in a correct posture state.

  The sponge plate 5 is reciprocally conveyed a plurality of times between the supply-side squeeze roller pair 6, the feed roller pair 8 and the discharge-side squeeze roller pair 7 and cleaned cleanly, and then sent out from between the discharge-side squeeze roller pair 7 to the discharge side. Then, it is dropped and supplied to the sponge plate container 36. Thereafter, the next sponge plate 5 that has been moved to the supply position by the sponge plate automatic supply device 35 is supplied between the supply-side squeezing roller pair 6 by the operation of the transfer member. 5 is performed. As described above, by setting a predetermined number of sponge plates 5 in the sponge plate automatic supply device 35, these sponge plates 5 are automatically and sequentially supplied to the supply-side squeezing roller pair 6, and then cleaned cleanly. After that, it is discharged from the discharge-side squeezing roller pair 7 and stored in the sponge plate container 36.

FIG. 5 shows a different embodiment of the pair of feed rollers, and the thickness of the upper roller 80A of the pair of feed rollers 80 is the thickness (outer diameter) of the intermediate portion in the length direction, and the thickness (outer diameter) of both end portions.
