  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a laver production apparatus 1 according to an embodiment of the present invention. This laver production apparatus 1 is an apparatus for automatically producing dry laver (plate laver), and a frame 3 in which a plurality of rectangular laver ridges 2 are arranged side by side in the front-rear direction (direction passing through the paper surface in FIG. 1), By transporting while passing between a plurality of chain conveyors 4 composed of a pair of transport chains arranged at the front and rear, each laver rice cake 2 passes through the paper making unit 11, the dewatering unit 12, the drying unit 13, and the peeling unit 14 in this order. It is the composition which makes it. A plurality of frames 3 can be installed side by side in the left-right direction (the left-right direction of the paper surface in FIG. 1), which is the traveling direction of the chain conveyor 4. Each chain conveyor 4 is driven intermittently, and the frame 3 on which the laver cocoons 2 are installed advances in the running direction of the chain conveyor 4 by a certain distance every certain time.

  The paper making unit 11 performs a paper making operation for making raw nori on each nori cocoon 2. The paper making unit 11 includes a paper making hoe 11a in which fresh laver that has been washed and shredded is stored. The paper making part 11 descends and comes into contact with the seaweed hoe 2 that has been transported to the work position by the chain conveyor 4. The fresh seaweed is placed on each seaweed jar 2. At this time, the water contained in the raw nori drops downward through the nori cocoon 2, and the raw nori is formed into a rectangular shape according to the shape of the paper mash 11 a and is made on the nori cocoon 2.

  The dehydration unit 12 performs a dehydration operation for removing moisture from the raw nori made on each nori cocoon 2. As shown in FIGS. 2 and 3, the dehydrating unit 12 includes upper and lower lifting bodies 21 (an upper lifting body 21 a and a lower lifting body 21 b) in the housing 20. The upper elevating body 21a and the lower elevating body 21b are arranged vertically with the chain conveyor 4 running in the housing 20 in between. A sponge member mounting portion 22 is attached to each of the upper and lower lifting bodies 21, and a block-like sponge member 23 is detachably mounted to each sponge member mounting portion 22.

  2 and 3, an elevating body drive motor 24 is fixed to the housing 20 on the right side of the lower elevating body 21b. A drive shaft 24a of the elevating body drive motor 24 protrudes forward from the housing 20, and a drive sprocket 25 is attached to the tip thereof. Both the front and rear end portions of the upper elevating body 21 a and the front and rear end portions of the lower elevating body 21 b both protrude and extend outward of the housing 20. Below the lower elevating body 21b, a shaft member 27 rotatably held by a bearing member 26 fixed to the housing 20 extends in a horizontal posture in parallel with the lower elevating body 21b. A front end portion of the shaft member 27 protrudes forward from the housing 20, and a driven sprocket 28 is provided at the front end portion of the protruding shaft member 27. The drive sprocket 25 and the driven sprocket 28 are arranged on the same plane and are connected by a drive chain 29.

  In FIG. 3, a pair of cams 30 are attached to both front and rear ends of the shaft member 27, and the lower lifting body 21 b is in contact with the pair of cams 30 from above. As shown also in FIG. 2, a rod lower end pivot portion 28a is provided to project forward at a position eccentric from the rotational center axis of the driven sprocket 28, and a rod is disposed at the front end of the upper elevating body 21a. An upper end pivot part 31 is provided to protrude forward. The rod upper end pivot part 31 and the rod lower end pivot part 28a are connected to each other by a connecting rod 32 on the outside (front) of the housing 20.

  4A to 4D, when the elevating body drive motor 24 is actuated to drive the drive sprocket 25, the driven sprocket 28 is rotated through the drive chain 29 (in FIGS. 4A to 4D). The upper lifting / lowering body 21a moves up and down via the connecting rod 32. Further, the shaft member 27 is rotated by the rotation of the driven sprocket 28, and the lower elevating body 21 b is moved up and down via the cam 30. As a result, the upper lifting body 21a and the lower lifting body 21b move away from each other (FIG. 4 (a) → FIG. 4 (b) → FIG. 4 (c)) (FIG. 4 (c) → FIG. 4 (). d) → Repeat FIG. 4 (a)).

  While the upper and lower lifting bodies 21 are separated, the laver rice cake 2 is carried between the upper and lower lifting bodies 21 by the chain conveyor 4 (FIG. 4A), and the upper and lower lifting bodies 21 (that is, the upper and lower sponge members 23 are moved). ) The raw laver is sandwiched by the upper and lower sponge members 23 together with the laver cocoon 2 by the approaching action (FIG. 4C). As a result, the moisture contained in the raw nori is absorbed by the upper and lower sponge members 23 and the moisture is removed (dehydrated) from the raw nori. The seaweed rice cake 2 on which the raw seaweed having absorbed moisture is placed is carried out of the working position by the chain conveyor 4 while the upper and lower lifting bodies 21 are separated from each other (that is, the upper and lower sponge members 23). The next laver 2 is carried to the working position (FIG. 4 (a)).

  During the dehydration operation (that is, during laver production), a mesh-like sheet member ST is set in a horizontal position between the upper sponge member 23 and the laver cocoon 2 (shown by a solid line in FIG. 1). (See sheet member ST). The sheet member ST is interposed between the upper sponge member 23 and the nori cocoon 2 when the laver cocoon 2 is sandwiched from above and below by the upper and lower sponge members 23 (during dehydration work), so that the upper sponge member 23 is produced. This prevents direct contact with the nori and prevents the raw nori from sticking to the upper sponge member 23 when the upper and lower sponge members 23 are separated. The sheet member ST is removed from between the upper and lower sponge members 23 by being moved in a horizontal plane direction (rightward here) during the cleaning operation of the upper and lower sponge members 23 described later (in FIG. 1). (See the sheet member ST indicated by a one-dot chain line).

  The drying unit 13 performs a drying operation for drying the raw nori that has been dehydrated to produce dry nori on each nori cocoon 2. As shown in FIG. 1, the drying unit 13 includes an upper and lower conveyor mechanism (an upper conveyor mechanism 4 </ b> A and a lower conveyor mechanism 4 </ b> B) composed of upper and lower chain conveyors 4 having a large number of partition parts 4 s attached at regular intervals. Yes. Each of the upper conveyor mechanism 4A and the lower conveyor mechanism 4B moves the laver 2 while holding the frame 3 in an upright position between two adjacent partition portions 4s. The upper conveyor mechanism 4A receives and holds the laver cocoon 2 from which the water content of the raw laver has been removed by the dewatering unit 12 and holds it, and reciprocates it in the left-right direction. The lower conveyor mechanism 4B sequentially receives and holds the frame 3 from the upper conveyor mechanism 4A and reciprocates in the left-right direction in the same manner as the upper conveyor mechanism 4A. A hot air blower 13W is provided in the drying unit 13, and the raw laver on each laver cocoon 2 is dried in a short time by the hot air blown by the hot air blower 13W.

  The peeling unit 14 performs a peeling operation for peeling dry seaweed from the laver cocoon 2. In FIG. 1, the peeling unit 14 receives each laver cocoon 2 on which dry laver has been generated together with the frame 3 by the chain conveyor 4, and peels dry laver from the laver cocoon 2 by the peeling mechanism 14 a. The dried seaweed peeled off from the laver cocoon 2 at the peeling portion 14 is carried to the outside of the laver production apparatus 1 by a conveyor device (not shown).

  In the laver production apparatus 1 having the above-described configuration, the upper and lower sponge members 23 provided in the dewatering unit 12 are periodically cleaned. For this reason, the dehydrating unit 12 is provided with a sponge cleaning unit 40 that is inserted between the upper and lower sponge members 23 and cleans both surfaces facing the upper and lower sides (FIGS. 5 and 6A, 6B). ).

  5 and 6 (a) and 6 (b), the sponge cleaning unit 40 is provided at the moving base 41 that is moved in the left-right direction (that is, in the horizontal plane direction) and at the tip end portion (left end portion) of the moving base 41. A cylindrical rotating member 42 is also provided (see also FIG. 7). The left end of the moving base 41 is provided with a support shaft 43 centering on an axis (axis line) 43J extending in the front-rear direction (that is, the horizontal plane direction orthogonal to the moving direction of the moving base 41). The member 42 is attached while being inserted through the support shaft 43. As described above, in the present embodiment, the sponge cleaning unit 40 is configured to include the rotating member 42 that is rotatably provided around the horizontal shaft 43J. The moving base 41 is a member that rotatably supports the rotating member 42 around the horizontal shaft 43J in the sponge cleaning unit 40.

  5 and 6 (a) and 6 (b), a cleaning motor 44 is provided at the right end of the moving base 41. The drive shaft of the cleaning motor 44 extends forward, and a drive-side sprocket 45 is attached to the tip thereof. A driven-side sprocket 46 is provided at an intermediate portion in the front-rear direction of the rotating member 42. The driving side sprocket 45 and the driven side sprocket 46 are arranged on the same plane and are connected by a connecting chain 47. When the cleaning motor 44 is actuated to drive the drive side sprocket 45, the rotational driving force is transmitted to the driven side sprocket 46 via the connecting chain 47, and the rotating member 42 to which the driven side sprocket 46 is attached is supported by the support shaft. It rotates around 43 (that is, around the axis 43J).

  In FIG. 7, a cleaning liquid passage SL is built in the moving base 41, and communicates with a cleaning liquid supply hole SA that opens on the front end surface of the moving base 41 (a surface facing the rotating member 42 in the horizontal direction). . A flexible cleaning liquid supply pipe SK is connected to the cleaning liquid passage SL. When the cleaning liquid is supplied into the cleaning liquid supply pipe SK by a cleaning liquid supply pump (not shown), the cleaning liquid is discharged from the cleaning liquid supply hole SA.

  5 and 6 (a) and 6 (b), the sponge cleaning unit 40 is driven by the unit moving mechanism 50 and moves in the left-right direction within the housing 20. The unit moving mechanism 50 is provided with a pair of front and rear chain units 53 formed by spanning a chain 52 around a plurality of sprockets 51 disposed on the front and rear inner walls of the housing 20. The plurality of sprockets 51 constituting each chain unit 53 include a right upper sprocket 51a, a left upper sprocket 51b, a left lower sprocket 51c, a lower intermediate sprocket 51d, a right lower sprocket 51e, and a right intermediate sprocket 51f. 51 are spanned in this order.

  The upper right sprockets 51 a of the front and rear chain units 53 are connected to each other by a connection shaft 54 extending in the front-rear direction in the housing 20, and the connection shaft 54 is rotationally driven by a shaft drive motor 55. The chain 52 engaged with the lower left sprocket 51c, the lower intermediate sprocket 51d, and the lower right sprocket 51e is in a horizontal posture, and the front and rear ends of the moving base 41 are connected to the lower intermediate sprocket 51d of the front and rear chain units 53. It is attached to the area (base attachment area) between the lower right sprocket 51e.

  Of the plurality of sprockets 51 constituting each chain unit 53, the lower intermediate sprocket 51d, the lower right sprocket 51e, and the right intermediate sprocket 51f are attached to the swing plate 57. The swing plate 57 is swingable about a swing shaft 56 coaxial with the rotation shaft of the lower intermediate sprocket 51d. The pair of front and rear rocking plates 57 are, by an actuator (for example, a cylinder) (not shown), an extended position (FIG. 8A) where the base mounting area is in a horizontal posture and a storage position (FIG. and b)) can be swung around the swing shaft 56.

  When the shaft drive motor 55 is actuated to rotationally drive the connecting shaft 54, the front and rear chain units 53 run synchronously, and the sponge cleaning unit 40 moves in the left-right direction within a predetermined movable range. Here, the movable range of the sponge cleaning unit 40 is a position where the entire sponge cleaning unit 40 has moved to the rightmost position, and a standby position where the rotating member 42 is positioned to the right of the upper and lower sponge members 23 (FIG. 6). (A)), the cleaning end position where the entire sponge cleaning unit 40 has moved to the left and the left end of the rotating member 42 is located to the left of the upper and lower sponge members 23 (FIG. 6B). ) And the range.

  When performing a cleaning operation for cleaning the upper and lower sponge members 23, the operator first performs a feeding operation of the chain conveyor 4 so that the nori cocoon 2 is not positioned between the upper and lower sponge members 23, and the sheet member ST is moved. It is moved in the horizontal plane direction (leftward) and removed from between the upper and lower sponge members 23 (sheet member ST indicated by a one-dot chain line in FIG. 1), and an operation of rotating the drive shaft of the elevator drive motor 24 is performed. Thus, the upper and lower lifting bodies 21 are positioned at a position (referred to as a cleaning position) in which the distance between the opposing surfaces of the upper and lower sponge members 23 is a predetermined value.

  When the operator moves the upper and lower lifting bodies 21 to the cleaning position, the operator moves the unit moving mechanism 50 by the shaft drive motor 55 while rotating the rotating member 42 by the cleaning motor 44 to move the sponge cleaning unit 40. Move from the standby position toward the cleaning end position. As a result, the sponge cleaning unit 40 enters between the upper and lower sponge members 23 so that the rotating member 42 is inserted between the upper and lower lifting bodies 21, and the outer peripheral surface of the rotating member 42 is formed between the upper and lower sponge members 23. It contacts both opposing surfaces (both the lower surface of the upper sponge member 23 and the upper surface of the lower sponge member 23).

  When the rotating member 42 is rotated and inserted between the upper and lower sponge members 23 and the entire sponge cleaning unit 40 is moved to the left as it is, the opposing surfaces of the upper and lower sponge members 23 are placed on the outer surface of the rotating member 42. The dirt that slides relative to the sponge member 23 is scraped off by the rotating member 42 (FIG. 9 (a) → FIG. 9 (b) → FIG. 9 (c)). In the present embodiment, since the rotating member 42 is forcibly rotated by the cleaning motor 44, the relative frictional force that the surface of the sponge member 23 receives from the outer peripheral surface of the rotating member 42 is large, and dirt attached to the sponge member 23 is effective. Is dropped.

  As described above, in the present embodiment, the unit moving mechanism 50 has the sponge cleaning unit 40 in a horizontal plane orthogonal to the shaft 43J in a state where the outer peripheral surface of the rotating member 42 is in contact with both opposing surfaces of the upper and lower sponge members 23. It is configured to move in the direction (left-right direction). Further, the cleaning motor 44 serves as a rotation drive unit that rotates the rotation member 42 around the shaft 43J while the outer peripheral surface of the rotation member 42 is in contact with both opposing surfaces of the upper and lower sponge members 23. .

  When the rotating member 42 is rotated, the cleaning liquid is supplied from the cleaning liquid supply pipe SK to the cleaning liquid passage SL, and the cleaning liquid SJ is discharged from the cleaning liquid supply hole SA (FIGS. 9A, 9B, and 9C). Accordingly, during the cleaning operation of the upper and lower sponge members 23, the cleaning liquid is supplied to the rotating member 42 and the sponge member 23, and the cleaning effect of the sponge member 23 can be enhanced.

  In the present embodiment, the cross section of the rotating member 42 orthogonal to the shaft 43J is substantially elliptical. Here, “substantially elliptical shape” refers to an elliptical shape (FIG. 10A) or a polygonal shape approximated to an elliptical shape as a whole (FIG. 10B). Thus, since the rotating member 42 has a substantially elliptical shape, the upper and lower sponge members 23 not only slide relative to the outer surface of the rotating member 42 but also by the rotating operation of the rotating member 42. Compressed intermittently (pressed in the thickness direction). For this reason, the dirt adhering to the sponge member 23 can be removed very efficiently.

  When the sponge member 23 is cleaned, the sponge cleaning unit 40 as described above is reciprocated in the left-right direction once or a plurality of times. As a result, when the dirt adhering to the upper and lower sponge members 23 is sufficiently removed, the sponge cleaning unit 40 is positioned at the standby position, and the cleaning operation is completed. When the cleaning operation is completed, the sponge cleaning unit 40 is positioned at the retracted position (FIGS. 2 and 8B), so that the laver rice cake 2 can be conveyed by the chain conveyor 4 and the sheet member ST is moved. It is set between the upper and lower sponge members 23 so that nori can be produced by the nori production apparatus 1.

  Here, in the present embodiment, the vertical dimension of the movement base 41 is larger than the interval between the upper and lower sponge members 23 in the state of being located at the cleaning position. For this reason, when the moving base 41 moves between the upper and lower sponge members 23, the moving base 41 comes into contact with both the upper and lower sponge members 23 (that is, sandwiched between the upper and lower sponge members 23). The moving base 41 is only supported at its front and rear ends by a pair of chain units 53, and when the rotating member 42 is driven to rotate, the entire moving base 41 tends to vibrate. By contacting both the upper and lower sponge members 23 (between the upper and lower sponge members 23), the vibration of the moving base 41 can be suppressed, the stable rotation state of the rotating member 42 can be maintained, and sound can be reduced. it can.

  Further, conventionally, the sheet member that prevents raw seaweed from adhering to the sponge member 23 is provided so as to individually wrap each sponge member 23, but in the present embodiment, the sheet member ST is dehydrated. Sometimes the upper and lower sponge members 23 are inserted in the horizontal direction (right side in FIG. 1) between the upper sponge member 23 and the laver cocoon 2 and moved in the horizontal plane direction (left side in FIG. 1). It can be removed from between the members 23. For this reason, the sheet member ST can be easily removed during the cleaning operation of the sponge member 23, and the rotating member 42 does not rub the sheet member ST, so that the sheet member ST can be prevented from being damaged.

  As described above, the laver production apparatus 1 according to the present embodiment moves the sponge cleaning unit 40 between the upper and lower sponge members 23 while rotating the rotary member 42 during the cleaning operation of the upper and lower sponge members 23. The outer peripheral surface of the rotating member 42 is rubbed against both opposing surfaces of the upper and lower sponge members 23 to scrape off the dirt adhering thereto, so that the dirt adhering to the sponge member 23 is sufficiently removed. Can do.

  In the above-described embodiment, the rotary member 42 has a substantially elliptical cross section. However, the cross sectional shape of the rotary member 42 does not necessarily have to be a substantially elliptical shape, and may be a circle or other shapes. It does not matter. However, as described above, if the cross-sectional shape of the rotating member 42 is substantially elliptical, the upper and lower sponge members 23 are intermittently compressed by the rotating member 42 during the cleaning operation, and the rotating member 42. This is preferable because it receives friction from the outer surface of the surface and can effectively remove the dirt adhering to the sponge member 23.

  In the above-described embodiment, the cleaning motor 44 that rotationally drives the rotating member 42 is attached to the moving base 41 and moves integrally with the moving base 41. The driven sprocket 46 may be driven by a chain that is fixed to 20 and routed through the sprocket. In the above-described embodiment, the upper and lower lifting bodies 21 in the dewatering unit 12 are driven up and down by the lifting body drive motor 24 provided in the dewatering unit 12. In the case of a configuration driven by the rotational power of one main drive motor, the upper and lower lifting bodies 21 may be driven up and down by transmitting the rotational power of the main drive motor.

  There is provided a seaweed manufacturing apparatus capable of sufficiently removing dirt adhered to a sponge member during cleaning of the sponge member.
