Description

[Technical Field]

[0001] The present invention relates to a seaweed peeling device, and more particularly to a seaweed peeling device that peels dried seaweed sheets, which have been dried in a drying chamber of a seaweed production apparatus, from a seaweed screen held by a seaweed screen holder. [Background technology]

[0002] In a nori manufacturing device for producing dried sheet-shaped nori, the raw nori is rolled up on a rectangular nori mat, dehydrated, and then passed through a drying chamber together with the nori mat to dry, and then only the dried nori is peeled off from the nori mat. A number of seaweed mats are held as a unit in a seaweed mat holder, and the seaweed mat holder is circulated and transported by a transport mechanism consisting of an attachment chain connected to it, whereby the above-mentioned operations are carried out sequentially on the seaweed mats.

[0003] In the peeling section, where the dried seaweed is completely peeled off the screen, it must be peeled off without tearing the dried seaweed. For this reason, various seaweed peeling devices have been proposed, but none of them are reliable and the dried seaweed tends to tear when peeled off, which remains a problem.

[0004] Therefore, the present applicant has previously proposed a seaweed peeling device (main peeling unit) that enables dried seaweed to be more reliably peeled from a seaweed screen (see Patent Document 1).

[0005] The peeling unit used in Patent Document 1 has a belt with a suction surface that sucks up the dried seaweed adhering to the underside of the seaweed screen, and is equipped with a suction rotating belt that rotates the belt while sucking up the dried seaweed to transport the dried seaweed, a belt lifting means that raises and lowers the suction rotating belt to move the suction surface closer to and away from the underside of the seaweed screen, a chuck part that holds and releases the rod member, and a chuck moving means that moves the chuck part holding the rod member along a predetermined trajectory to cause the seaweed screen to perform a folding operation in the seaweed screen holder so that the dried seaweed sucked onto the suction surface can be peeled off from the seaweed screen, and the suction rotating belt is inclined downward in the direction opposite to the movement of the chuck part when peeling off the dried seaweed. With this type of seaweed peeling device, the tip of the chuck, holding the rod, can be brought close to the top surface of the suction rotating belt without interfering with the belt. As a result, the folding angle of the seaweed screen holder can be kept small (the angle at which the seaweed screen is pulled can be kept sharp), resulting in smooth separation of the dried seaweed from the screen. Furthermore, the upward force acting on the dried seaweed can be minimized. This further prevents wrinkles and tears in the dried seaweed when peeled, ensuring improved quality. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Publication No. 2023-167738 Summary of the Invention [Problem to be solved by the invention]

[0007] As described above, the seaweed peeling device proposed in Patent Document 1 enables dried seaweed to be more reliably peeled from the seaweed screen and transported to the next process, but it is desirable to more reliably prevent the dried seaweed from breaking when peeling, thereby ensuring improved quality of the dried seaweed. The inventors further conducted extensive research and discovered that by devising the installation condition of the suction rotating belt and the transport mechanism for the peeled dried seaweed, it is possible to more reliably prevent the dried seaweed from wrinkling and tearing during peeling and to further improve the efficiency of peeling the dried seaweed, thereby completing the present invention.

[0008] The present invention has been made in consideration of the above circumstances, and aims to provide a seaweed peeling device that can more reliably prevent wrinkles and tears in dried seaweed when peeling it, thereby ensuring improved quality of dried seaweed and improved production efficiency. [Means for solving the problem]

[0009] In order to achieve the above object, the configuration of the seaweed peeling device according to the present invention is as follows: (1) A seaweed peeling device having a main peeling unit that peels off sheet-shaped dried seaweed from a seaweed mat held by a seaweed mat holder, The laver screen holder has a frame-like shape consisting of a pair of horizontal and vertical rods, one end of the laver screen being held by one of the horizontal rods, and the other end of the laver screen being connected to a rod member parallel to the other horizontal rod; The main peeling portion is a dried seaweed conveying means having a belt with a suction surface for suctioning the dried seaweed adhering to the underside of the seaweed screen, and conveying the dried seaweed by rotating the belt while suctioning the dried seaweed; a belt lifting means for lifting and lowering the dried seaweed conveying means to move the suction surface toward and away from the underside of the seaweed screen; a chuck portion that holds and releases the rod member; a chuck moving means for moving the chuck portion holding the rod member along a predetermined trajectory, thereby causing the laver screen to perform a folding operation in the laver screen holder so that the dried laver sucked onto the suction surface is peeled off from the laver screen; The dried seaweed conveying means rotates the belt along the moving direction of the chuck when peeling the dried seaweed from the seaweed screen, The chuck portion is characterized by being disposed on the side of the belt.

[0010] The above-mentioned configuration (1) of the seaweed peeling device of the present invention has the following effects. In other words, because the chunk portion is positioned on the side of the belt, the tip of the chuck portion does not interfere with the upper surface of the belt when the dried seaweed is peeled off from the seaweed screen. Therefore, when peeling off the seaweed, the suction surface of the dried seaweed conveying means can be brought into close contact with the dried seaweed on the underside of the seaweed screen. This allows the folding angle when the seaweed screen is folded back in the seaweed screen holder to be kept small (the angle at which the seaweed screen is pulled can be kept sharp), and the dried seaweed and seaweed screen can be easily separated, preventing wrinkles and tears in the dried seaweed. Furthermore, when the dried seaweed peeled from the nori screen is placed on the belt and transported, the dried seaweed is placed in a line on the belt. Therefore, by moving the belt in a direction along the line of dried seaweed, the dried seaweed can be transported efficiently. Therefore, with the configuration (1) above, it is possible to provide a seaweed peeling device that can more reliably prevent wrinkles and tears in the dried seaweed when peeled, thereby ensuring improved quality of the dried seaweed.

[0011] In the above-mentioned configuration (1) of the laver peeling device of the present invention, it is preferable to configure it as in the following (2) to (5).

[0012] (2) The dried seaweed conveying means is characterized by having three or more pulleys for tensioning the belt. According to the preferred configuration of (2) above, the portion of the belt stretched by the two pulleys is placed facing the seaweed screen, and by adjusting the pressure of the belt applied by the other pulley, the portion of the belt facing the seaweed screen can be kept under tension.

[0013] (3) In the configuration of (2) above, the diameter of the pulley located at the end of the belt from which the dried seaweed is discharged is 16 mm or more and 17 mm or less. According to the preferred configuration of (3) above, when the dried seaweed is discharged, the dried seaweed is easily separated from the belt, and the possibility of the dried seaweed moving downward without separating from the belt can be reduced.

[0014] (4) When the belt lifting means lowers the dried seaweed conveying means, a pair of discharge rollers is further provided, which are positioned opposite the end of the belt from which the dried seaweed is discharged, and which discharge the dried seaweed conveyed by the belt outside the dried seaweed conveying means. According to the preferred configuration of (4) above, the rotation speed of the discharge roller pair is set to be faster than the moving speed of the belt, so that the dried seaweed on the belt can be quickly discharged off the belt as it passes through the discharge roller pair, thereby enabling a quick transition to the process of peeling the dried seaweed from the next laver screen.

[0015] (5) In the configuration of (4) above, a dry seaweed conveying means is further provided, which has a conveying belt provided with a suction surface that sucks the dry seaweed discharged to the outside of the dry seaweed conveying means by the pair of discharge rollers, and conveys the dry seaweed by rotating the conveying belt while sucking the dry seaweed. The belts are arranged in a line equal to the number of the laver screens, The dried seaweed placed on the belt is then placed on the discharge belt all at once. According to the preferable configuration of (5) above, the dried seaweed that has passed through the pair of discharge rollers can be conveyed out in a line. [Effects of the Invention]

[0016] According to the present invention, a seaweed peeling device can be provided that can more reliably prevent the dried seaweed from breaking when peeled, thereby ensuring improved quality of the dried seaweed. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0018] The present invention will be described in more detail below using preferred embodiments, but the following embodiments are merely examples of realizing the present invention and the present invention is not limited thereto.

[0019] [Overall configuration of seaweed production equipment] First, the overall configuration of a nori seaweed production apparatus for producing dried nori sheets will be described with reference to FIG.

[0020] FIG. 1 is a schematic diagram showing the overall configuration of a nori seaweed production apparatus for producing dried nori sheets.

[0021] The laver production apparatus 1 shown in FIG. 1 has a function of producing dried laver 16 (see FIG. 4) by drying raw laver that has been laid on a laver mat 3c (see FIG. 2). As shown in Figure 1, the seaweed production device 1 is configured by arranging a paper-making section 5, a dewatering section 6, a peeling section 7, and a holder cleaning section 9 along the conveying path of a conveyor 4, which is configured to circulate and transport seaweed mat holders 3 (see Figures 2 and 3) using an endless chain 2, which is made up of attachment chains connected endlessly, and combining this with a drying chamber 10.

[0022] The endless chain 2 is looped around one drive sprocket 11 and three driven sprockets 12-14 in a horizontally long rectangular shape (a two-stage configuration with an upper-stage transfer conveyor 4U and a lower-stage transfer conveyor 4L), and a pair of these sprockets are arranged facing each other at the same height in the direction perpendicular to the plane of the paper in Fig. 1 in order to hold the nori mat holder 3 at both ends. By driving the drive sprocket 11 to rotate (see arrow A in Fig. 1) by, for example, a drive motor (not shown), the endless chain 2 can be rotated intermittently in the clockwise direction in Fig. 1 at predetermined intervals.

[0023] Of the conveying paths of the conveyor 4, which is made up of an upper and lower two-tiered endless chain 2, a separating section 5 and a dewatering section 6 are arranged in this order from upstream to downstream in the conveying direction (from left to right in FIG. 1) on the conveying path of the upper conveyor 4U, which is located at a higher position. Furthermore, of the conveying paths of the conveyor 4, a lower conveyor 4L, which is located at a lower position, a peeling section 7 and a holder washing section 9 are arranged in this order from upstream to downstream in the conveying direction (from right to left in FIG. 1). The nori mat holders 3 are transported sequentially to the separating section 5, dewatering section 6, drying chamber 10, peeling section 7, and holder washing section 9.

[0024] The dehydrated seaweed mat holder 3 is carried into the drying chamber 10 through the conveyance path of the upper conveyor 4U, which is located at a higher position among the conveyance paths of the conveyor 4. The drying chamber 10 is equipped with a two-stage drying conveyor (not shown), for example, consisting of an upper conveyor and a lower conveyor, and the raw seaweed on the seaweed mat 3c (see FIG. 2) held by the seaweed mat holder 3 is dried into dried seaweed 16 while being moved through the drying chamber 10 by the drying conveyor. The dried seaweed mat holder 3 is then handed over to the conveyance path of the lower conveyor 4L, which is located at a lower position among the conveyance paths of the conveyor 4.

[0025] The paper-making unit 5 performs a process of paper-making raw laver onto a laver mat 3c held by a laver mat holder 3. The dehydration unit 6 dehydrates the raw nori seaweed on the nori screen 3c that has been papered by the paper-making unit 5. In the nori production apparatus 1, the dehydration unit 6 is composed of a suction dehydration unit 6a, which dehydrates the nori seaweed dough by sucking water from the nori seaweed dough that has been papered on the top surface of the nori screen 3c, and a press dehydration unit 6b, which dehydrates the nori seaweed dough by pressing a sponge-like pad against it, arranged in this order from upstream to downstream in the conveyance direction. The peeling unit 7 peels the dried seaweed 16 from the seaweed screen 3c held by the seaweed screen holder 3. In the seaweed production apparatus 1, the peeling unit 7 is composed of a preliminary peeling unit (edge ​​peeling unit) 7a that peels only the edge (edge) of the dried seaweed 16 from the seaweed screen 3c, and a main peeling unit (seaweed peeling device) 7b that peels the entire dried seaweed 16 from the seaweed screen 3c, which are arranged in this order from the upstream side to the downstream side in the conveying direction. The holder washing unit 9 washes the nori mat holder 3 with water after the dried nori 16 has been peeled off. After washing, the nori mat holder 3 is transported to the papering unit 5 again.

[0026] [Configuration of the seaweed rack holder] Next, the configuration of the laver mat holder, which is a component of the laver production apparatus, will be described with reference to FIGS.

[0027] Figure 2 is a diagram for explaining a nori mat holder, which is a component of a nori manufacturing apparatus for manufacturing sheet-shaped dried nori ((a) is a plan view, (b) is a side view), and Figure 3 is an enlarged side view of the nori mat holder shown in Figure 2. 2(a) and 3 indicates the direction in which the laver rack holder 3 in the laver production apparatus 1 is transported by the lower-stage transport conveyor 4L.

[0028] 2 and 3, the nori mat holder 3 used to roll up and dry raw nori seaweed comprises two parallel first rods 3a (horizontal rods and stick members) and multiple (three in FIG. 2) nori mats 3c stretched and held between the two first rods 3a via fasteners 3b. The nori mat holder 3 also comprises two second rods 3d (the second rods 3d on the upstream side of the conveying direction are the "horizontal rods") extending parallel to the first rods 3a on the outside of the first rods 3a. Two connecting members 3j (vertical rods) extending perpendicular to the second rod portions 3d are stretched across the second rod portions 3d, with three laver mats 3c sandwiched between them.

[0029] Two support members 3e, 3e are provided inside the two connecting members 3j, 3j in parallel with the two connecting members 3j, 3j, with the three laver racks 3c sandwiched between them. One end of the support member 3e is fixed to the underside of the second rod portion 3d (horizontal rod) on the upstream side in the conveying direction, and the other end of the support member 3e is fixed to the upper surface of the second rod portion 3d on the downstream side in the conveying direction. The first rod portion 3a (rod member) on the upstream side in the conveying direction is located on the upper surface of the support member 3e, and the first rod portion 3a (horizontal rod) on the downstream side in the conveying direction is located on the underside of the support member 3e. Both ends of the first rod portion 3a (rod member) on the upstream side in the conveying direction are pressed from below against stoppers 3h fixed to the upper surface of the second rod portion 3d (horizontal rod) by torsion springs 3i (spring members) attached to the support members 3e, 3e. Also, both ends of the first rod portion 3a (horizontal rod) on the downstream side in the conveying direction are pressed from above against stoppers 3h fixed to the lower surface of the second rod portion 3d by torsion springs 3i (spring members) attached to the support members 3e, 3e. This causes the nori screen 3c to be fixed in a stretched position. The free ends of the torsion springs 3i (spring members) protrude from the nori screen holder 3 toward the upstream or downstream side in the conveying direction.

[0030] The laver mat 3c is made by arranging a number of rod-shaped resin members 3f in parallel and fastening them with thin strings 3g. The rod-shaped members 3f have different surface properties, such as roughness or fine stripes, on the front and back sides, and are fastened together in parallel with the same surfaces. The laver mat 3c thus produced has different surface properties on the front and back sides, making it possible to select the surface that is more suitable for use as the sheet surface depending on the characteristics of the raw laver used.

[0031] When the laver rack holder 3 is transported in the laver production apparatus 1, the laver rack holder 3 is transported in a state in which both end portions of the second rod portions 3d, 3d are supported from the lower surface side.

[0032] By configuring the laver rack holder 3 as described above, the front-to-back orientation of the laver rack holder is eliminated, and for example, the laver rack holder can be turned over and used on both sides.

[0033] [Configuration of the Nori peeling device (main peeling section)] Next, the configuration of the seaweed peeling device (main peeling unit) in one embodiment of the present invention will be described with reference to FIG.

[0034] FIG. 4 is a side view showing a part of a seaweed peeling device according to one embodiment of the present invention. 4 indicates the direction in which the laver rack holder 3 is transported by the lower-stage transport conveyor 4L in the laver production apparatus 1.

[0035] As shown in FIG. 4, the laver peeling device (main peeling unit) 15 has a belt 17 provided with a suction surface 17a that sucks in the dried laver 16 adhering to the underside of the laver screen 3c, and includes a suction rotating belt device (dried laver conveying means) 18 that conveys the dried laver 16 by rotating the upper part of the belt 17 that is sucking the dried laver 16 along the conveying direction of the laver screen holder 3, a belt lifting / lowering means 19 that raises and lowers the suction rotating belt device 18 to move the suction surface 17a toward and away from the underside of the laver screen 3c, and a chuck unit 20 that holds and releases the first rod portion 3a (rod member) on the upstream side of the laver screen holder 3 in the conveying direction. The device is equipped with a chuck moving means 21 that causes the seaweed screen 3c in the seaweed screen holder 3 to perform a folding operation by moving the chuck portion 20 holding the first rod portion 3a (rod member) along a predetermined trajectory along the conveying direction of the seaweed screen holder 3 so that the dried seaweed 16 sucked onto the suction surface 17a is peeled off from the seaweed screen 3c, a discharge roller pair 30 that discharges the dried seaweed 16 conveyed by the suction rotating belt device 18 to the outside of the suction rotating belt device 18, and a belt conveyor device 31 that carries the dried seaweed 16 discharged by the discharge roller pair 30 and conveys it to a predetermined destination.

[0036] The suction rotary belt device 18 includes a suction chamber 18a, a driving pulley 18b, and three driven pulleys 18c, 18d, and 18e. The suction chamber 18a is disposed inside the belt 17 and sucks the dried seaweed 16 on the belt 17 through holes 17b (see FIG. 5) in the belt 17. A hole (not shown) is formed on the top surface of the suction chamber 18a, and when this hole overlaps with the hole 17b (see FIG. 5) in the belt 17, air flows from the outside to the inside, sucking the dried seaweed 16 on the belt 17.

[0037] The drive pulley 18b and the three driven pulleys 18c, 18d, and 18e are disposed inside the belt 17 and tension the belt 17. The rotation axes of the drive pulley 18b and the three driven pulleys 18c, 18d, and 18e are parallel to each other and extend along the longitudinal direction of the suction chamber 18a. The drive pulley 18b transmits rotation transmitted from a drive source to the belt 17, causing the belt 17 to move in a circular motion.

[0038] Driven pulleys 18c and 18d are disposed on both sides of the upper portion of suction chamber 18a, with driven pulley 18c disposed downstream in the conveying direction of nori rack holder 3 and driven pulley 18d disposed upstream in the conveying direction of nori rack holder 3. Driven pulley 18c has a smaller diameter than driven pulley 18d, and in this embodiment, is set to a diameter of 16.3 mm. The portion of belt 17 stretched between driven pulleys 18c and 18d abuts against the upper surface of suction chamber 18a.

[0039] The driven pulley 18e adjusts the tension applied to the belt 17 by pressing the belt 17 from the inside. The driving pulley 18b is disposed below the driven pulleys 18c and 18d, and the driven pulley 18e abuts against a portion of the belt 17 stretched by the driving pulley 18b and the driven pulley 18d.

[0040] The chuck moving means 21 is configured to move a moving part 22, to which the chuck part 20 is connected at the bottom, along a guide groove 23a formed in a guide beam 23 via a link mechanism (not shown) driven by a chuck horizontal moving mechanism (not shown). As a result, the moving part 22 reciprocates along the guide groove 23a (see arrows A and B in FIG. 4), and accordingly, the chuck part 20 reciprocates in the horizontal direction. Then, the chuck unit 20 is moved forward in the horizontal direction (see arrow A in FIG. 4) while holding the first rod unit 3a (rod member) on the upstream side of the conveying direction of the nori screen holder 3, thereby causing the nori screen 3c to perform a folding operation. After the folding operation, the chuck unit 20 is moved back in the horizontal direction (see arrow B in FIG. 4), thereby returning the nori screen 3c to the extended position.

[0041] The discharge roller pair 30 consists of a seaweed skipping roller 30a and an intermediate roller 30b. The intermediate roller 30b has a smaller diameter than the seaweed skipping roller 30a and a larger diameter than the driven pulley 18c. The nip between the seaweed skipping roller 30a and the intermediate roller 30b is positioned on the movement path of the dried seaweed 16 on the belt 17. The rotation speed of the discharge roller pair 30 is set faster than the movement speed of the belt 17. Therefore, the dried seaweed 16 on the belt 17 moves quickly off the belt 17 as it passes through the discharge roller pair 30.

[0042] The belt conveyor device 31 includes an endless circular discharge belt 32, a drive pulley 33a and a driven pulley 33b that tension the discharge belt 32, and a suction chamber (not shown) located inside the discharge belt 32. The discharge belt 32 moves and stops when the drive pulley 33a is rotated and stopped. A plurality of through holes 32a, each about 8 mm in diameter, are formed on both sides of the width of the discharge belt 32, aligned in the circumferential direction. When the suction chamber (not shown) is driven, air is sucked through the through holes 32a, and the dried seaweed 16 is adsorbed and held on the suction surface of the discharge belt 32. The belt conveyor device 31 is provided with a curved plate-shaped nori receiver 34 on the inside (toward the discharge belt 32) near the side opposite to the side on the discharge roller pair 30 side. The nori receiver 34 prevents the dried nori 16 sent out from the discharge roller pair 30 from flying out of the belt conveyor device 31.

[0043] The number of through holes 32a aligned at the end of the discharge belt 32 on the discharge roller pair 30 side is set to be fewer than the number of through holes 32a aligned at the end on the opposite side, on the seaweed receiver 34 side. As a result, the suction force at the end on the seaweed receiver 34 side is increased, and the leading end of the dried seaweed 16 delivered from the discharge roller pair 30 is attracted and held by the end of the discharge belt 32 on the seaweed receiver 34 side. This reduces the possibility of the dried seaweed 16 flying out of the belt conveyor device 31 and makes it possible to align the dried seaweed 16 on the discharge belt 32.

[0044] Fig. 5 is a plan view showing a part of a nori seaweed peeling device according to one embodiment of the present invention. In Fig. 5, the nori seaweed rack holder 3 is indicated by a two-dot chain line. In this embodiment, the nori seaweed rack holder 3 can hold six nori seaweed racks 3c.

[0045] Three belts 17 are arranged side by side in the suction chamber 18a of the suction rotary belt device 18. The drive pulley 18b and three driven pulleys 18c, 18d, and 18e that tension the three belts 17 may be shared by the three belts 17 or may be provided independently. Two suction rotating belt devices 18 are arranged side by side facing the nori screen holder 3. This allows the belts 17 to face each of the six nori screens 3c. Then, by moving the chuck unit 20 forward and backward in the horizontal direction while holding the first rod unit 3a, the six nori screens 3c simultaneously perform a folding motion, and the dried nori 16 is simultaneously placed on the six belts 17. Furthermore, the suction rotating belt devices 18 and the discharge roller pair 30 simultaneously place the dried nori 16 on the six belts 17 onto the discharge belt 32. As a result, the dried nori 16 is lined up in a row on the discharge belt 32, and the dried nori 16 is carried out by the discharge belt 32 while maintaining this state.

[0046] Both ends of the six laver screens 3c are supported by a single first rod 3a. Chucks 20 that hold and release the first rod 3a are located at both longitudinal ends and the center of the two aligned suction rotating belt devices 18. This prevents the chucks 20 from coming into contact with the upper surface of the belt 17.

[0047] 6 to 8 are explanatory diagrams showing the seaweed peeling operation of the seaweed peeling device according to one embodiment of the present invention.

[0048] First, as shown in Fig. 6(a), the transfer conveyor 4 places the laver mat 3c on the upper part of the suction rotating belt device 18. At this time, the chuck part 20 is positioned above the first rod part 3a. Next, as shown in Figure 6(b), the chuck 20 is lowered to hold the first rod 3a at its tip, and the belt lifting means 19 raises the suction rotating belt device 18 to bring the belt 17 into close contact with the laver screen 3c. At this time, the suction chamber 18a is performing air suction. As a result, the dried laver 16 on the laver screen 3c is sucked toward the belt 17.

[0049] Next, as shown in FIG. 7(a), the chuck portion 20 is moved forward to peel the dried seaweed 16 from the seaweed rack 3c and move the dried seaweed 16 onto the belt 17. Next, as shown in Figure 7(b), the suction rotating belt device 18 is lowered by the belt lifting means 19, and the leading end of the dried seaweed 16 is made to face the discharge roller pair 30, and the belt 17 and the discharge roller pair 30 are rotated. As a result, as shown in Figure 8(a), the dried seaweed 16 is moved by the belt 17 toward the discharge roller pair 30, and is sent out to the belt conveyor device 31 by the discharge roller pair 30, and as shown in Figure 8(b), the dried seaweed 16 is placed on the belt conveyor device 31. At this time, the chuck portion 20 is returned to return the first rod portion 3a to its original position.

[0050] Thereafter, while the belt conveyor device 31 is transporting the dried seaweed 16, the chuck portion 20 is moved upward to disengage from the first rod portion 3a. Then, the transport conveyor 4 moves the next seaweed mat 3c holding the dried seaweed 16, returning to the state shown in Figure 6(a).

[0051] In the seaweed peeling device of this embodiment, as described above, the chuck 20 that holds the first rod 3a is positioned between adjacent belts 17, 17. The belt 17, which transports the dried seaweed 16 peeled from the seaweed screen 3c, moves in a circular motion along the direction of the chuck 20. This prevents the chuck 20 from contacting the belt 17, preventing the dried seaweed 16 from tearing due to contact with the dried seaweed 16. Furthermore, the chuck 20 can be moved closer to the suction chamber 18a by the thickness of the belt 17, allowing the belt 17 to be moved closer to the dried seaweed 16. This reduces the gap between the dried seaweed 16 and the belt 17, reducing tearing and wrinkling during seaweed peeling. In this embodiment, the chuck 20 is positioned between adjacent suction rotating belt devices 18, 18, preventing the chuck 20 from contacting the suction chamber 18a. This makes it possible to raise the suction rotating belt device 18 until the belt 17 comes into close contact with the dried seaweed 16, thereby significantly reducing tearing and wrinkling when peeling the seaweed.

[0052] Furthermore, if the dried seaweed 16 peeled from the laver screen 3c is transported directly to a predetermined location as in the conventional method, it is necessary to transport all of the dried seaweed 16 on the belt so that there is no dried seaweed 16 on the belt before the first rod portion 3a of the next laver screen 3c arrives at the chuck portion 20. This requires a certain level of transport speed. In contrast, according to this embodiment, the transport distance of the belt 17 is short, so it is possible to remove the dried seaweed 16 from the belt 17 in a short time after the dried seaweed 16 is placed on the belt 17. This means that the discharge speed is not as high as in the conventional method, and furthermore, it is possible to increase the efficiency of laver peeling.

[0053] Furthermore, since the belt 17 is driven by three or more pulleys (drive pulley 18b, driven pulleys 18c, 18d, and 18e), it is possible to apply an appropriate tension to the belt 17, and the belt 17 can be maintained without slack above the suction chamber 18a. Furthermore, the diameter of the driven pulley 18c is small at 16.3 mm, which creates a sharp curve in the conveying path of the dried seaweed 16. This prevents the dried seaweed 16 from being transported downward without separating from the belt 17. Furthermore, the dried seaweed 16 transported by the belt 17 passes through a pair of discharge rollers 30 and is placed on a belt conveyor device 31 for further transport. The pair of discharge rollers 30 consists of an upper seaweed skipping roller 30a and a lower intermediate roller 30b, with the intermediate roller 30b having a smaller diameter than the seaweed skipping roller 30a. Therefore, the dried seaweed 16 tends to face diagonally downward when passing through the pair of discharge rollers 30, and the dried seaweed 16 can be stably placed on the belt conveyor device 31.

[0054] Although one embodiment of the present invention has been described above, the embodiments of the present invention are not limited to the above-described embodiment. For example, according to the above-described embodiment, the chucks 20 that hold and release the first rod 3a are disposed at both longitudinal ends and the center of the two aligned suction rotating belt devices 18, but the present invention is not limited thereto, and the chucks 20 may be disposed between adjacent belts 17, 17, and may be disposed at any location other than a location that abuts at least the upper surface of the belts 17.
