Description

[Technical field]

[0001] The present invention relates to a sheet-making device that supplies raw materials to a screen and forms the raw materials into a sheet on the screen, and to a seaweed manufacturing machine having the sheet-making device. [Background technology]

[0002] Conventionally, a papermaking device has been used to supply raw materials such as dried seaweed and Japanese paper to a screen and to paper the raw materials into a sheet on the screen. For example, in a seaweed manufacturing machine for producing dried seaweed, a papermaking device, a dehydrating device, and a drying device are arranged in this order on a conveying path along which a conveying device continuously conveys a seaweed screen that will become a screen, and the papermaking device supplies seaweed raw materials consisting of seaweed raw material and water to the seaweed screen to paper seaweed dough of a predetermined shape on the seaweed screen, and then the dehydrating device dehydrates the seaweed dough, and the drying device dries the seaweed dough to produce dried seaweed (for example, see Patent Document 1).

[0003] In the paper making device of this nori manufacturing machine, a valve body for opening and closing the supply port of the paper making box, which has a supply port for supplying raw materials to a screen, is provided inside the paper making box and can be raised and lowered, and a lifting arm for raising and lowering the valve body is linked to the valve body.

[0004] In the papermaking apparatus, as the lifting arm rises, the opening and closing valve body rises to open the supply port of the papermaking basin, thereby supplying the raw material to the sieve and making the raw material into a sheet on the sieve.

[0005] In this conventional papermaking apparatus, the amount of raw material supplied to the sieve is adjusted by adjusting the amount of raw material supplied to the papermaking box. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2022-179532 A Summary of the Invention [Problem to be solved by the invention]

[0007] However, in the conventional papermaking apparatus described above, even if the amount of raw material supplied to the papermaking basin is adjusted, if the time during which the opening / closing valve body is raised and the supply port of the papermaking basin is open is too short, not all of the raw material will be supplied to the sieve and will remain in the papermaking basin, which may result in the desired amount of raw material not being supplied to the sieve. [Means for solving the problem]

[0008] Therefore, in the present invention as claimed in claim 1, an opening and closing valve body for opening and closing the supply port of a papermaking box is provided inside the papermaking box, which has a supply port for supplying raw material to a sieve, and a lifting arm for raising and lowering the opening and closing valve body is linked to the opening and closing valve body, so that the opening and closing valve body is raised as the lifting arm rises to open the supply port of the papermaking box, thereby supplying raw material to the sieve and papermaking the raw material into a sheet on the sieve.In this papermaking device, an adjustment device for adjusting the raisedmost position of the opening and closing valve body by abutting against the upper part of the lifting arm is provided on the opening and closing valve body so as to be movable up and down, and an adjustment mechanism for moving the adjustment device up and down is connected to the adjustment device, so that the raisedmost position of the opening and closing valve body can be adjusted by moving the adjustment device up and down with the adjustment mechanism.

[0009] In the present invention according to claim 2, in the present invention according to claim 1, the adjustment mechanism is supported by a papermaking box, and the adjustment mechanism and the adjustment tool are interlocked and connected so as to be slidable up and down relative to each other.

[0010] In addition, in the present invention according to claim 3, a seaweed production machine includes the paper making device according to claim 1 or 2, and a raw material consisting of seaweed raw material and water is paper-made on a tray. Effect of the Invention

[0011] The present invention provides the following advantages.

[0012] That is, in the present invention, in a papermaking apparatus, an opening / closing valve body for opening and closing the supply port of a papermaking box is provided inside the papermaking box, which has a supply port for supplying raw material to a sieve, and which can be raised and lowered, and a lifting arm for raising and lowering the opening / closing valve body is linked to the opening / closing valve body, so that as the lifting arm rises, the opening / closing valve body rises to open the supply port of the papermaking box, thereby supplying raw material to the sieve and papermaking the raw material into a sheet on the sieve. An adjuster for adjusting the raisedmost position of the opening / closing valve body by contacting the upper part of the lifting arm is provided on the opening / closing valve body so as to be movable up and down, and an adjustment mechanism for moving the adjuster up and down is connected to the adjuster, so that the raisedmost position of the opening / closing valve body can be adjusted by moving the adjuster up and down with the adjustment mechanism. Therefore, by mechanically adjusting the adjuster with the adjustment mechanism, the raisedmost position of the opening / closing valve body can be easily adjusted, and the time during which the opening / closing valve body is raised to open the supply port of the papermaking box, i.e., the amount of raw material supplied to the sieve, can be well adjusted.

[0013] In particular, when the adjustment mechanism is supported by the papermaking tub and the adjustment mechanism and the adjustment tool are connected together so that they can slide vertically relative to one another, the adjustment mechanism and the adjustment tool can be maintained in a well-connected state even when the opening / closing valve body is raised and lowered, and the amount of raw material supplied to the sieve can be well adjusted.

[0014] Furthermore, when the above-mentioned paper-making device is applied to a seaweed manufacturing machine to paper-make raw materials consisting of seaweed raw materials and water onto a screen, the amount of raw materials supplied to the screen can be well adjusted, and the weight and thickness of the dried seaweed produced can be well controlled.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] The specific configuration of the paper making device according to the present invention and a seaweed production machine having the paper making device will be described below with reference to the drawings. In the following description, the paper making device is provided in a seaweed production machine for producing dried seaweed using a seaweed raw material consisting of seaweed raw material and water as a raw material and a seaweed mat as a mat, but the paper making device according to the present invention is not limited to the case of being provided in a seaweed production machine to produce dried seaweed, and can be applied to a paper making device used to paper-form raw materials (such as seaweed, seafood, noodles, vegetables, fruits, salt, sludge, etc.) into sheets on a mat, such as dried seaweed or Japanese paper.

[0017] As shown in Fig. 1, the nori seaweed production machine 1 is arranged with a production machine 2 and a dryer 3 arranged in front of each other. The production machine 2 and the dryer 3 are provided with intermittent conveying devices 6, 7, and 8 for intermittently conveying a reed frame 5 on which a plurality of nori seaweed screens (screens) 4 are arranged in the left-right width direction and stretched so as to be freely attached and detached.

[0018] The nori screen 4 is transported together with the screen frame 5 by the intermittent conveying device 6 of the manufacturing machine 2 from the upper front end to the upper rear end of the manufacturing machine 2, and then handed over from the intermittent conveying device 6 of the manufacturing machine 2 to the intermittent conveying device 7 above the dryer 3. After that, the nori screen 4 is transported together with the screen frame 5 by the intermittent conveying device 7 above the dryer 3 from the upper front end to the upper rear end of the dryer 3, then turned back downward at the upper rear end of the dryer 3, transported from the middle rear end to the middle front end of the dryer 3, and finally handed over from the upper intermittent conveying device 7 above the dryer 3 to the lower intermittent conveying device 8 via the intermittent conveying device 6 of the manufacturing machine 2 at the middle front end of the dryer 3. Thereafter, the Nori screen 4 is transported together with the screen frame 5 by the intermittent conveying device 8 below the dryer 3 from the front end of the middle part of the dryer 3 to the rear end of the middle part, then turned downward at the rear end of the middle part of the dryer 3, transported from the rear end of the lower part of the dryer 3 to the front end of the lower part, and handed over again from the intermittent conveying device 8 below the dryer 3 to the intermittent conveying device 6 of the manufacturing machine 2 at the front end of the lower part of the dryer 3. Thereafter, the Nori screen 4 is transported together with the screen frame 5 by the intermittent conveying device 6 of the manufacturing machine 2 from the rear end of the lower part of the manufacturing machine 2 to the front end of the lower part, then turned upward at the front end of the lower part of the manufacturing machine 2. As a result, a conveying path is formed in the Nori manufacturing machine 1 for continuously conveying the Nori screen 4 together with the screen frame 5.

[0019] On this transport path, a papermaking device 9 provided in the manufacturing machine 2, a dewatering device 10, a drying device 11 provided in the dryer 3, and a peeling device 12 provided in the manufacturing machine 2 are arranged in this order.

[0020] In the seaweed producing machine 1, the intermittent conveying devices 6, 7, 8, the paper making device 9, the dehydrating device 10, the drying device 11, and the peeling device 12 are operated in conjunction with each other by a driving device 13. A control device 14 is connected to this driving device 13, and the driving of the paper making device 9, the dehydrating device 10, the drying device 11, and the peeling device 12 is controlled by the control device 14 via the driving device 13.

[0021] The Nori production machine 1 transports the multiple Nori screens 4 together with the screen frames 5 along the transport path, and the paper-making device 9 supplies Nori raw material (raw material) consisting of raw Nori seaweed and water to the top surface of each Nori screen 4 to paper Nori dough of a predetermined shape (for example, square), and then the Nori dough is dehydrated in the dehydration device 10, and then the Nori dough is forcibly dried with hot air in the drying device 11 to make dried Nori, and then the dried Nori is peeled off from each Nori screen 4 by the peeling device 12, and then the Nori screens 4 together with the screen frames 5 are transported back to the paper-making device 9 again, and these operations are repeated continuously. In this way, the Nori production machine 1 continuously produces dried Nori from the Nori dough, and moreover, produces multiple sheets of dried Nori at the same time.

[0022] In this nori seaweed producing machine 1, as shown in FIG. 2, the paper making device 9 has a nori seaweed dough supplying mechanism 15 and a water retention mechanism 16 arranged opposite to each other above and below the nori screen 4 transported by the intermittent transport device 6 along the transport path.

[0023] The water retention mechanism 16 has a rectangular perforated plate 17 fixed to the manufacturing machine 2, and a flexible, bag-like water retention bag 18 attached to the lower part of the perforated plate 17 so that it can be compressed and expanded. The perforated plate 17 has a plurality of water-passing holes 19 that penetrate vertically. The center of the water retention bag 18 is attached to the upper end of a lifting body 20 that is linked to the driving device 13, and the inside of the water retention bag 18 is compressed or expanded by raising and lowering the lifting body 20 with the driving device 13.

[0024] The Nori dough supply mechanism 15 has a papermaking box 21 fixed to the manufacturing machine 2, an opening / closing valve 22 arranged inside the papermaking box 21 so that it can rise and fall, and a papermaking frame 23, which is a hollow rectangular box with open top and bottom ends, arranged so that it can rise and fall on the outer periphery of the lower end of the papermaking box 21. The papermaking box 21 has a plurality of supply ports 24 at its bottom. The opening / closing valve 22 is attached to the lower end of a lifting rod 25 linked to the drive device 13, and the lifting rod 25 is raised and lowered by the drive device 13 to open and close the supply ports 24 of the papermaking box 21. The papermaking frame 23 is attached between a pair of lifting bodies 26, 26 linked to the drive device 13, and the lifting body 26 is raised and lowered by the drive device 13 to move toward and away from the Nori screen 4.

[0025] As shown in Fig. 3, the Nori-making machine 1 drives the driving device 13 by the control device 14, which drives the intermittent conveying devices 6, 7, and 8 to convey the Nori screen 4 intermittently at a predetermined distance along the conveying path at a predetermined cycle time (see Fig. 3(a)). After that, the Nori-making machine 1 lowers the lifting rod 25 by the driving device 13, and the lower end opening surface of the papermaking frame 23 abuts against the upper surface of the perforated plate 17 via the Nori screen 4 (see Fig. 3(b)). As a result, the Nori screen 4 is sandwiched between the papermaking frame 23 and the perforated plate 17 (water retention bag 18). After that, the Nori-making machine 1 raises the lifting body 20 by the driving device 13, and compresses the water retention bag 18 by lifting the lower center of the water retention bag 18 upward (see Fig. 3(c)). As a result, the water stored inside the water retention bag 18 passes through the Nori screen 4 from the water holes 19 of the perforated plate 17 and is supplied to the inside of the papering frame 23, so that the top surface of the Nori screen 4 becomes filled with water. After that, the Nori production machine 1 uses the drive device 13 to raise the lift rod 25, which raises the opening and closing valve body 22 and opens the supply port 24 of the papering box body 21 (see Figure 3(d)). As a result, the Nori raw material stored inside the papering box body 21 is supplied from the supply port 24 of the papering box body 21 to the inside of the papering frame 23. At this time, since the inside of the papering frame 23 has already been filled with water supplied from the water retention bag 18, the Nori raw material is dispersed inside the papering frame 23 by the water. After that, the Nori making machine 1 lowers the lifting rod 25 by the drive device 13, lowers the opening and closing valve body 22, and closes the supply port 24 of the papering box 21 (see FIG. 3(c)). This stops the supply of Nori raw material from the papering box 21 to the papering frame 23. After that, the Nori making machine 1 lowers the lifting body 20 by the drive device 13, and pulls down the center of the lower part of the water retention bag 18, thereby expanding the water retention bag 18 (see FIG. 3(b)). As a result, the seaweed raw material and water filled inside the papering frame 23 above the seaweed screen 4 are sucked up by the water retention bag 18, and the moisture passes through the water passage holes 19 in the seaweed screen 4 and the perforated plate 17 and flows into the inside of the water retention bag 18, while the solid content (raw seaweed) sticks to the upper surface of the seaweed screen 4, so that the seaweed raw material is papered by the seaweed screen 4 and seaweed dough is formed on the upper surface of the seaweed screen 4.Thereafter, the Nori making machine 1 raises the lifting body 26 by the driving device 13 to raise the papermaking frame 23 (see FIG. 3(a)). The Nori making machine 1 repeatedly and continuously performs the above operations at a predetermined cycle time preset in the control device 14. The amount of Nori dough produced on the Nori mat 4 (and thus the weight and thickness of the dried Nori) is determined by the time that the papering box 21 is in an open state.

[0026] In the nori seaweed producing machine 1, the sheet making measure 21 and the opening / closing valve 22 of the nori seaweed dough supply mechanism 15 are configured as shown in Figs.

[0027] The papermaking box 21 has a hollow rectangular box-like papermaking box body 27 with an open top and a support 28 detachably attached to the upper opening of the box.

[0028] The bottom of the papermaking box body 27 has multiple (eight in this example) supply ports 24 evenly spaced from the center of the papermaking box body 21, and an overflow trough 29 is formed in the middle of the front side, sloping downward toward the front side. The seaweed raw material is stored inside the papermaking box body 27, and excess seaweed raw material is discharged (recovered) from the overflow trough 29.

[0029] The support 28 is formed with a hollow cylindrical support tube 30 that penetrates vertically at the center (the center of the papermaking box 21), and the lifting rod 25 of the opening / closing valve body 22 is inserted into the support tube 30 so as to be able to move up and down freely.

[0030] The on-off valve body 22 comprises a rectangular plate-shaped lift plate 31 whose center is attached horizontally to the lower end of the lift rod 25, upper ends of connecting bodies 32 extending vertically up and down attached to the four corners of the lift plate 31, plate-shaped valve holding plate 33 attached horizontally to the lower ends of the four connecting bodies 32, and expandable silicone valves 34 for opening and closing each supply port 24 detachably attached to the lower part of the valve holding plate 33. The valve holding plate 33 has upper and lower through holes formed evenly from the center.

[0031] An adjustment device 35 is screwed onto the upper end of the lifting rod 25 so as to be movable up and down in order to adjust the amount of lifting (the opening time of the supply port 24 of the paper making box 21: the amount of seaweed raw material supplied), and a biasing means 36 is provided in the middle of the rod to bias the valve 34 of the opening / closing valve body 22 downward toward the supply port 24.

[0032] The biasing means 36 comprises a disk-shaped pressure plate 37 provided on the upper side of the middle part of the lifting rod 25 so as to be able to slide up and down along the lifting rod 25, and a disk-shaped biasing plate 38 attached (fixed) to the lower side of the middle part of the lifting rod 25 so as to be able to adjust its vertical position, and a spiral-shaped spring 39 which can freely expand and contract up and down is provided between the pressure plate 37 and the biasing plate 38.

[0033] Between the adjustment tool 35 and the pressure plate 37, there are disposed the distal ends of a pair of left and right lifting arms 40, 40 which are interlocked with the drive device 13 and rotate at a constant speed within a predetermined vertical range.

[0034] Then, as the lifting arm 40 moves downward, the lower tip of the lifting arm 40 comes into contact with the upper surface of the pressure plate 37 of the biasing means 36, and as the lifting arm 40 moves further downward, it presses the pressure plate 37 downward.As a result, the valve 34 of the opening / closing valve body 22 is urged toward the supply port 24 of the papermaking body 21 by the expanding and contracting force of the spring 39 of the biasing means 36, and the supply port 24 is closed by the valve 34.

[0035] In addition, as the lifting arm 40 moves upward, the upper tip of the lifting arm 40 abuts the underside of the adjustment device 35, and as the lifting arm 40 moves further upward, the lifting arm 40 presses the adjustment device 35 upward, whereby the valve 34 of the opening / closing valve body 22 of the papermaking body 21 rises from the supply port 24 of the papermaking body 21, opening the supply port 24.

[0036] Therefore, in the Nori dough supply mechanism 15, when the lifting arm 40 rises and the upper tip abuts against the underside of the adjuster 35, the supply port 24 is opened and the Nori raw material is supplied to the Nori screen 4. After that, in the Nori dough supply mechanism 15, the lifting arm 40 continues to rise to the highest position, and accordingly the opening / closing valve body 22 (valve 34) continues to rise to the highest position relative to the papering box body 21 (supply port 24). After that, in the Nori dough supply mechanism 15, the lifting arm 40 descends, and accordingly the opening / closing valve body 22 descends, and when the lifting arm 40 descends and the upper tip separates from the underside of the adjuster 35, the descent of the opening / closing valve body 22 stops, the supply port 24 is closed by the valve 34, and the supply of the Nori raw material to the Nori screen 4 is stopped. Then, in the seaweed dough supply mechanism 15, the lifting arm 40 descends and the lower tip presses the pressure plate 37, and the valve 34 of the opening / closing valve body 22 presses the supply port 24 of the paper making box body 21 to prevent the seaweed dough from leaking out of the supply port 24.

[0037] In this way, in the Nori dough supply mechanism 15, the papering measure 21 is in an open state and Nori raw material is supplied to the Nori screen 4 from the time when the lifting arm 40 rises and its upper tip abuts against the underside of the adjustment tool 35 until the valve body 22 (valve 34) rises to its highest position and then the lifting arm 40 descends and its upper tip separates from the underside of the adjustment tool 35. Therefore, the amount of Nori dough (the Nori raw material supplied to the Nori screen 4) that is papered onto the Nori screen 4 (and thus the weight and thickness of the dried Nori) is determined by the time when the papering measure 21 is in an open state, i.e., the highest position of the valve body 22.

[0038] In the seaweed dough supply mechanism 15, since the highest position of the lifting arm 40 is constant, when the adjuster 35 of the opening / closing valve body 22 is moved upward along the lifting rod 25, the highest position of the opening / closing valve body 22 (valve 34) becomes lower, the time that the papermaking measure body 27 is in an open state becomes shorter, and the amount of seaweed dough (seaweed raw material supplied to the seaweed measure 4) made onto the seaweed mat 4 decreases; on the other hand, when the adjuster 35 of the opening / closing valve body 22 is moved downward along the lifting rod 25, the highest position of the opening / closing valve body 22 (valve 34) becomes higher, the time that the papermaking measure body 27 is in an open state becomes longer, and the amount of seaweed dough (seaweed raw material supplied to the seaweed mat 4) made onto the seaweed mat 4 increases.

[0039] In order to mechanically move the adjustment device 35 up and down, the nori dough supply mechanism 15 has an adjustment mechanism 41 for moving the adjustment device 35 up and down interlocked with the adjustment device 35, and by moving the adjustment device 35 up and down with the adjustment mechanism 41, the uppermost position of the opening / closing valve body 22 can be adjusted.

[0040] The adjustment mechanism 41 attaches brackets 42, 42 extending vertically to the left and right upper parts of the support body 28 of the papermaking box 21, and attaches a motor holder 43 extending horizontally between the upper rear sides of the left and right brackets 42, 42, and also attaches a rectangular plate-shaped gear holder 44 horizontally between the upper ends of the left and right brackets 42, 42.

[0041] A motor 45 serving as a drive source is attached to the motor holder 43. A drive shaft 46 of the motor 45 protrudes upward, and a drive gear 47 is attached horizontally to the tip (upper end) of the drive shaft 46.

[0042] A circular opening 48 is formed in the center of the gear holder 44, penetrating it vertically. A connecting body 50 is attached to the opening 48 via a bearing 49 so as to be rotatable horizontally, and a driven gear 51 is attached horizontally to the lower part of the connecting body 50.

[0043] The connecting body 50 has a circular opening 52 that penetrates vertically in the center, and a plurality of (here, two) circular insertion holes 53, 53 that penetrate vertically on the outside are formed evenly from the center (equally spaced (180 degree intervals) in the circumferential direction). An encoder disk 54 is attached to the top, and the amount of rotation of the encoder disk 54 is detected by an encoder sensor 55 attached to the upper right side of the gear holding body 44.

[0044] The drive gear 47 is engaged with the driven gear 51. A circular opening 56 penetrating vertically is formed in the center of the driven gear 51, and a plurality of (here, two) circular insertion holes 57, 57 penetrating vertically are formed evenly from the center (at equal intervals (180 degree intervals) in the circumferential direction) on the outside.

[0045] Several (here, two) cylindrical interlocking bodies 58, 58 attached (fixed) to the adjustment device 35 and protruding vertically upward are inserted into the insertion holes 53, 53 of the connecting body 50 and the insertion holes 57, 57 of the driven gear 51 so as to be movable up and down.

[0046] As a result, in the adjustment mechanism 41, the drive gear 47 of the motor 45 and the driven gear 51 are directly interlocked, and the driven gear 51 and the adjustment tool 35 are interlocked via interlocking bodies 58, 58 so as to be vertically slidable.

[0047] In addition, in the adjustment mechanism 41, the motor 45 and the encoder sensor 55 are connected to the control device 14, and the drive is controlled by the control device 14.

[0048] When the motor 45 is rotated clockwise in plan view from the state shown in Figures 7(a) and (b), the driven gear 51 rotates counterclockwise, and the adjuster 35 rotates counterclockwise accordingly and moves upward along the lift-down rod 25, resulting in the state shown in Figures 7(c) and (d). On the other hand, when the motor 45 is rotated counterclockwise in plan view from the state shown in Figures 7(c) and (d), the driven gear 51 rotates clockwise, and the adjuster 35 rotates clockwise accordingly and moves downward along the lift-down rod 25, resulting in the state shown in Figures 7(a) and (b).

[0049] In this way, the adjustment mechanism 41 can mechanically move the adjustment device 35 up and down, and when the lifting arm 40 is raised in the state shown in Figures 7(a) and (b) where the adjustment device 35 is in a relatively low position, the uppermost position of the opening / closing valve body 22 becomes relatively high, as shown in Figure 8(a), allowing a large amount of seaweed raw material to be supplied to the seaweed screen 4. On the other hand, when the lifting arm 40 is raised in the state shown in Figures 7(c) and (d) where the adjustment device 35 is in a relatively high position, the uppermost position of the opening / closing valve body 22 becomes relatively low, as shown in Figure 8(b), allowing a small amount of seaweed raw material to be supplied to the seaweed screen 4.

[0050] In addition, when the opening / closing valve body 22 rises, the upper end of the lifting rod 25 passes through the inside of the opening 56 of the driven gear 51 and the opening 52 of the connecting body 50, thereby avoiding collision between the rising and falling lifting rod 25 and the driven gear 51 or the connecting body 50, and also achieving a low overall height (compactness).

[0051] In the above-mentioned seaweed dough supply mechanism 15, an opening / closing valve body 22 is arranged so that it can rise and fall relative to a paper making measure body 21 fixed to the manufacturing machine 2, and an adjustment device 35 is provided on the opening / closing valve body 22 which rises and falls relative to the paper making measure body 21, and is adjustable by an adjustment mechanism 41 (motor 45 serving as a driving source) attached (fixed) to the paper making measure body 21 fixed to the manufacturing machine 2. In order to adjust the adjustment device 35, a driven gear 51 of the adjustment mechanism 41 and the adjustment device 35 are linked via an interlocking body 58 so that the adjustment mechanism 41 and the adjustment device 35 can slide vertically relative to each other.

[0052] In this way, it is sufficient that the adjustment mechanism 41 and the adjustment tool 35 are interlocked so that they can slide vertically relative to each other, and for example, as in the nori dough supply mechanism 59 shown in Figure 9, a motor 61 serving as the drive source of the adjustment mechanism 60 is attached to an opening / closing valve body 63 via a bracket 62, and a drive gear 65 attached horizontally to a drive shaft 64 of the motor 61 is vertically slidably engaged with a gear formed on the outer periphery of an adjustment tool 66 of the opening / closing valve body 63, thereby interlocking the adjustment mechanism 60 and the adjustment tool 66 so that they can slide vertically relative to each other. In the nori dough supply mechanism 59 in Figure 9, members having the same configuration as the nori dough supply mechanism 15 described above are designated by the same reference numerals and their explanations will be omitted.

[0053] As described above, the papermaking apparatus 9 is configured such that the papermaking box 21 has a supply port 24 for supplying the raw material (Nori raw material) to the screen (Nori screen 4), and the opening / closing valve bodies 22, 63 for opening and closing the supply port 24 of the papermaking box 21 are arranged so as to be able to be raised and lowered inside the papermaking box 21, and the lifting arm 40 for raising and lowering the opening / closing valve bodies 22, 63 is linked to the opening / closing valve bodies 22, 63, so that as the lifting arm 40 rises, the opening / closing valve bodies 22, 63 are raised to open the supply port 24 of the papermaking box 21, thereby supplying the raw material (Nori raw material) to the screen (Nori screen 4) and papermaking the raw material (Nori raw material) into a sheet on the screen (Nori screen 4).

[0054] The papermaking device 9 is configured so that adjustment devices 35, 66 for adjusting the raised position of the opening / closing valve bodies 22, 63 by abutting against the upper part of the lifting arm 40 are vertically movable on the opening / closing valve bodies 22, 63, and adjustment mechanisms 41, 60 for moving the adjustment devices 35, 66 vertically are connected to the adjustment devices 35, 66, so that the raised position of the opening / closing valve bodies 22, 63 can be adjusted by moving the adjustment devices 35, 66 vertically with the adjustment mechanisms 41, 60.

[0055] Therefore, in the papermaking apparatus 9 configured as described above, the uppermost position of the opening / closing valve body 22, 63 can be easily adjusted by mechanically adjusting the adjustment devices 35, 66 using the adjustment mechanisms 41, 60, and the time during which the opening / closing valve body 22, 63 is raised and the supply port 24 of the papermaking box body 21 is open, i.e., the amount of raw material (nori raw material) supplied to the screen (nori screen 4), can be precisely adjusted.

[0056] In addition, the papermaking device 9 has a configuration in which the adjustment mechanisms 41, 60 are supported by the papermaking container 21 or the opening and closing valve bodies 22, 63, and the adjustment mechanisms 41, 60 and the adjustment tools 35, 66 are interlocked and connected so as to be vertically slidable relative to each other.

[0057] Therefore, in the papermaking apparatus 9 having the above configuration, even if the opening / closing valve bodies 22, 63 are raised and lowered, the adjustment mechanisms 41, 60 and the adjustment devices 35, 66 can be maintained in a well-interlocked state, and the amount of raw material (nori raw material) supplied to the screen (nori screen 4) can be well adjusted.

[0058] The paper making device 9 is adapted to be applied to the Nori production machine 1 to make a sheet of paper from a raw material (Nori raw material) consisting of raw seaweed and water onto a reed (Nori reed 4).

[0059] Therefore, in the seaweed production machine 1, the amount of raw material (seaweed raw material) supplied to the screen (seaweed screen 4) can be appropriately adjusted, and the weight and thickness of the dried seaweed produced can be appropriately adjusted. [Explanation of symbols]
