Description

[Technical field]

[0001] The present invention relates to a roller-to-roller conveying system for seaweed, that is, to a conveying system for a roller-to-roller conveying device for seaweed. [Background technology]

[0002] 《Technical background》 In the production and processing lines of dried seaweed (hereafter simply referred to as seaweed), the seaweed is transported and processed in various ways. For transport, conveyors such as round belt transport devices, flat belt transport devices, and roller-to-roller transport devices are used. The roller-to-roller conveying device conveys the seaweed from an entrance roller to an exit roller spaced apart from the front and rear.

[0003] <<Prior Art: Roller-to-Roller Conveyor Device 1>> That is, as shown in Figs. 4, 5 and 6, the inter-roller conveying device 1 conveys seaweed A from an entrance roller 2 on the front side to an exit roller 3 on the rear side with a front-rear gap B therebetween. The entrance rollers 2 include a drive roller 4 and a driven roller 5 arranged above and below, and the exit rollers 3 also include a drive roller 6 and a driven roller 7 arranged above and below. When the exit roller 3 pinches the seaweed A, the entrance roller 2 pushes the pinched seaweed A out.

[0004] <<Prior Art: Regarding Guide Board 8>> The inter-roller conveying device 1 is provided with a guide plate 8 for guiding the conveyed seaweed A from below at a front-rear distance B. The guide plate 8 guides the seaweed A linearly from a tangent position C between the driving roller 4 and the driven roller 5 of the entrance rollers 2 to a tangent position D between the driving roller 6 and the driven roller 7 of the exit rollers 3. In the figure, reference numeral 9 denotes a round belt conveying device, which conveys seaweed A before and after the roller-to-roller conveying device 1. That is, the round belt conveying device 9 conveys seaweed A on a round belt 12 between roller 10 and entrance roller 2, and between exit roller 3 and roller 11. Summary of the Invention [Problem to be solved by the invention]

[0005] However, the following problems have been pointed out as issues regarding the conventional roller-to-roller conveying device 1 for seaweed A. Problem 1: Malfunctions such as bending, damage, and clogging occur. First, it was pointed out that the seaweed A was not smoothly sandwiched between the exit rollers 3, and malfunctions E such as bending, breakage, and clogging often occurred. That is, for example, in the case of seaweed A that has a low moisture content and is brittle, such as seaweed A produced on a secondary processing line that produces seaweed that is pasteurized or roasted, or seaweed A that has a strong flavor, the seaweed A was prone to deviating from the linear guide provided by the guide plate 8 during transportation, resulting in bending, floating, flapping, and other deformations F. As shown in FIG. 5(1), the tip A1 of the seaweed A hits the driven roller 7 of the exit roller 3 and becomes deformed, etc. F, and the tip A1 is not smoothly sandwiched at the tangent position D between the driven roller 7 and the driving roller 6, and shifts up or down from the tangent position D, resulting in deterioration and instability. As shown in FIG. 5(2), defects E such as bending, breakage, and clogging of seaweed A often occurred. (In contrast, as shown in FIG. 5(3), when the leading end A1 of the seaweed A hits the lower driving roller 6, the defect E can be easily avoided by adjusting the guide plate 8 up and down using the lifting means.)

[0006] Problem 2: Regarding the upper presser round belt and the upper presser guide plate Secondly, as a measure to prevent deformation F of the seaweed A at the exit roller 3 mentioned above and as a measure to prevent malfunction E, a measure was also developed to install an upper pressure round belt or an upper pressure guide plate (not shown) in the front-to-back space B between the entrance roller 2 and the exit roller 3. That is, measures were taken to install a round belt or a guide plate in front of the exit rollers 3 to press the transported seaweed A from above. However, although this measure was effective to some extent, it was pointed out that the maintenance was troublesome. That is, when the seaweed A got stuck between the lower guide plate 8, it was difficult to take it out and remove it. Furthermore, it was pointed out that the upper presser round belt required regular replacement. (In addition, 13 in Fig. 4 and Fig. 6 is an upper press round belt. This upper press round belt 13 is not for the above-mentioned exit roller 3 but for the entrance roller 2, but like the one for the exit roller 3, it is composed of a round belt 14 and a driving roller 15. The seaweed A is pressed down between the round belt 12 of the lower round belt conveyor 9, and is smoothly sandwiched at the tangent position C of the entrance roller 2.)

[0007] Problem 3: Transporting items to the inspection area Thirdly, it was difficult to install the upper pressure round belt and the upper pressure guide plate in the inspection section. That is, as shown in Figure 6, when inspection devices 18 such as a light source 16 and a camera 17 are arranged above and below in the front-to-back space B between the entrance roller 2 and the exit roller 3, a gap G is formed in the guide plate 8 to allow the irradiated light L to pass through. Therefore, it was difficult to install the upper presser round belt and the upper presser guide plate in such a front-to-rear space B. Therefore, the above-mentioned deformation F and the occurrence of the defect E remained as problems. Instead, it was considered to install the air blowing unit 19 toward the tangent position D of the exit roller 3. However, it was pointed out that the fatal problem of flapping of the seaweed A would occur due to the air blowing. Furthermore, it was also difficult to use the round belt conveying device 9 instead of the inter-roller conveying device 1 due to the passage of the irradiated light L. The roller-to-roller transport device 1 is still used for transport in the inspection section, and the above-mentioned problems have been pointed out. The problems with the roller-to-roller conveying device 1 have been described above.

[0008] About the present invention The roller-to-roller conveying system for seaweed according to the present invention has been made in consideration of the above-mentioned circumstances in order to solve the problems of the prior art. The present invention aims to propose a roller-to-roller transport system for seaweed that, first, allows the seaweed to be smoothly sandwiched between the exit rollers, second, is easy to maintain, and third, allows for easy transport through the inspection section. [Means for solving the problem]

[0009] Regarding each claim: The technical means of the present invention for solving such problems are as follows, as described in the claims. Regarding claim 1, the following applies: The seaweed inter-roller transport system of claim 1 relates to an inter-roller transport device that transports seaweed from a front entrance roller to a rear exit roller spaced apart from each other. The device is characterized by having a guide plate between the rollers that guides the transported seaweed from below at a front-to-rear interval, and a suction section attached to the guide plate. Regarding claim 2, the following applies: In the seaweed roller-to-roller conveying system of claim 2, in the system of claim 1, the outlet roller is provided with a driving roller and a driven roller above and below. The guide plate linearly guides the seaweed toward a tangential position between the drive roller and the driven roller of the outlet roller. The suction section is characterized by sucking the seaweed toward the guide plate, thereby following the linear pinching of the seaweed to the tangent position of the outlet roller.

[0010] Regarding claim 3, the following applies: In the seaweed conveying system between rollers of claim 3, in claim 2, the inlet roller also has a driving roller and a driven roller above and below. The guide plate is characterized in that it linearly guides the seaweed from a tangent position between the drive roller and the driven roller of the entrance rollers to a tangent position between the drive roller and the driven roller of the exit rollers. Regarding claim 4, the following applies: In the roller-to-roller conveying system for seaweed of claim 4, in the system of claim 3, the front-to-back distance between the entrance roller and the exit roller is less than the length of the seaweed. When the exit roller pinches the front end of the seaweed to be sucked in by the suction section, the entrance roller pushes out the rear end of the pinched seaweed.

[0011] Regarding claim 5, the following applies: The laver conveying system according to claim 5 is the same as that according to claim 2, in which the suction unit is incorporated in the guide plate at a position closer to the exit roller, and the suction hole is open flush with the upper surface of the guide plate. Regarding claim 6, the following applies: In the seaweed roller-to-roller conveying system of claim 6, in claim 5, the driven rollers of the inlet roller and the outlet roller consist of rotatable rollers pressed against the drive roller so as to be able to move up and down, and multiple units are arranged separately on the left and right. The suction portion is provided in a plurality of portions below the respective driven rollers of the outlet roller. The present invention is characterized in that the two types of sensors are arranged in a corresponding manner. Regarding claim 7, In the seaweed roller-to-roller conveying system of claim 7, in the manner of claim 1, a light source and a camera of an inspection device are arranged above and below in the front-to-back space between the entrance roller and the exit roller. The light source illuminates the seaweed being conveyed. The camera receives the light emitted from the light source through the seaweed. The guide plate is characterized by having a gap for passing the illuminated light.

[0012] <About the action> The present invention comprises such means and is as follows: (1) The roller-to-roller conveying device transports the seaweed from the entrance rollers to the exit rollers. (2) When the exit roller clamps the front end of the seaweed that has been sucked in by the suction section, the entrance roller pushes out the rear end of the seaweed that was clamped. (3) The seaweed roller-to-roller conveying system according to the present invention relates to such a roller-to-roller conveying device and is equipped with a guide plate and a suction unit. (4) The guide plate guides the seaweed linearly toward the tangent position between the driving roller and the driven roller of the inlet roller. (5) The suction section is incorporated into the guide plate near the exit roller, and the suction hole is flush with the top surface of the guide plate. (6) The suction section thus sucks the seaweed toward the guide plate, thereby following up on the linear clamping of the seaweed to the tangent position of the exit roller. The seaweed is sucked toward the guide plate so that it does not come off the guide plate and fall off, and the seaweed is clamped to the tangent position without resistance and without hitting the driven roller of the exit roller. (7) The seaweed conveying system between rollers according to the present invention operates as described above, resulting in the following: First, the seaweed is smoothly sandwiched between the outlet rollers of the conveying device between rollers. Curving, floating, flapping, and other deformations are prevented, and problems such as bending, breakage, and clogging are avoided. (8) Furthermore, the guide plate is incorporated into the suction section, which makes it easy to maintain, repair, and manage. (9) Furthermore, it can be applied to the transportation in the inspection section without any problems. The light source and camera of the inspection device are arranged above and below, and a gap is formed in the guide plate for the passage of the irradiated light, but the suction unit can be incorporated into the guide plate without any problems. Effect of the Invention

[0013] First effect: First, the seaweed is smoothly sandwiched between the exit rollers. The roller-to-roller conveying system for seaweed according to the present invention is characterized in that a suction unit is incorporated in the guide plate of the roller-to-roller conveying device, so that the seaweed is guided in a straight line reliably to the tangent position of the exit roller and smoothly sandwiched therein. Unlike the above-mentioned conventional roller conveying device, the conveyed seaweed is prevented from being curved, floating, fluttering, or otherwise deformed. It also does not shift up or down, causing defects or instability. As a result, defects such as bending, damage, clogging, etc. do not occur, and the seaweed is smoothly sandwiched at the tangential position between the driving roller and the driven roller of the outlet roller.

[0014] Second effect: Secondly, maintenance is easy. The seaweed conveying system according to the present invention is configured by incorporating a suction unit into the guide plate of the roller conveying device. Therefore, it does not require any special maintenance and is easy to maintain, care for, and manage. Unlike the above-mentioned conventional example, there is no need for troublesome maintenance. In other words, unlike the upper presser round belt and the upper presser guide plate, if the seaweed gets stuck during transportation, there is no need to take out and remove it, which is time-consuming. There is also no need to replace the round belt periodically.

[0015] The third effect Thirdly, transportation through the inspection section is possible without any problems. In the inspection section, a light source and a camera of the inspection device are disposed above and below between the entrance rollers and the exit rollers, and a gap is formed in the guide plate to allow the passage of the irradiated light. The laver conveying system according to the present invention can be applied to such inspection zone conveying without any problems. The suction unit can be easily installed near the exit roller of the guide plate. There is no problem with installation, unlike the above-mentioned conventional example of this type that requires the installation of an upper pressure round belt and an upper pressure guide plate. Thus, the effects of the present invention are remarkable and great, as all of the problems that existed in the prior art are solved. [Brief description of the drawings]

[0017] The present invention will now be described in detail with reference to FIGS. 1, 2 and 3. FIG. Overview of the Invention First, the outline of the present invention is as follows. The roller-to-roller transport system for seaweed A according to the present invention relates to an inter-roller transport device 1 that transports seaweed A from a front entrance roller 2 to a rear exit roller 3 with a front-to-rear gap B therebetween. The roller guide plate 8 guides the conveyed seaweed A from below at a front-rear distance B, and a suction section 20 is attached to the guide plate 8. The exit roller 3 has a driving roller 6 and a driven roller 7 on the top and bottom, and a guide plate 8 guides the seaweed A linearly toward a tangent position D between the driving roller 6 and the driven roller 7 of the exit roller 3. The suction section 20 is characterized in that it sucks the seaweed A toward the guide plate 8, and follows the seaweed A so that it is pinched linearly to the tangent position D of the outlet roller 3. The outline of the present invention is as above. The present invention will be described in more detail below.

[0018] <About the roller-to-roller conveying device 1> First, the inter-roller conveying device 1 will be described. In the production line for Nori A and the subsequent processing line, various processes are carried out while the Nori A is being transported. For transportation, conveyors such as a round belt transport device 9, a flat belt transport device (not shown), and a roller-to-roller transport device 1 are used. The inter-roller conveying device 1 conveys seaweed A from entrance rollers 2 at the front to exit rollers 3 at the rear with a front-to-rear gap B. The entrance rollers 2 are equipped with a driving roller 4 and a driven roller 5 at the top and bottom, and the exit rollers 3 are equipped with a driving roller 6 and a driven roller 7 at the top and bottom.

[0019] A further detailed description will be given of such inter-roller conveying device 1. The seaweed A typically has dimensions of about 210 mm (up to 230 mm) in length, 190 mm (up to 200 mm) in width, and 0.2 mm to 0.5 mm in thickness, and is in the form of a flexible, thin, generally sheet. The front-rear distance B between the entrance roller 2 and the exit roller 3 is less than the above-mentioned length of the seaweed A. Thus, when the exit roller 3 pinches the front end A1 of the seaweed A to be sucked in by the suction section 20, the entrance roller 2 pushes out the rear end A2 of the pinched seaweed A, and the seaweed A is then conveyed by the exit roller 3. The front-to-rear distance B is usually about 130 mm to 200 mm.

[0020] The drive rollers 4, 6 of the entrance roller 2 and the exit roller 3 are made of long cylindrical straight rollers, and are connected to a drive source such as a motor to be rotated. The driven rollers 5, 7 of the entrance roller 2 and the exit roller 3 are pressed against the driving rollers 4, 6 so as to be able to move up and down, and are rotatable rollers that rotate in response to the rotation of the driving rollers 4, 6. In the illustrated example, multiple rollers are arranged separately on the left and right. That is, as shown in Fig. 2(1), the driven rollers 5, 7 have a vertically long hole H drilled in a fixed bracket K for mounting and holding the driven rollers 5, 7, and the shafts S of the driven rollers 5, 7 are loosely inserted into the vertically long hole H so as to be movable up and down. Thus, the driven rollers 5, 7 are pressed against the driving rollers 4, 6 by their own weight, and can sandwich the seaweed A. The driven rollers 5, 7 in the illustrated example are roughly thin-walled tops or wheels, and two or three or more are arranged at intervals in the left-right direction, but they may also be a single straight roller rather than being divided into left and right types as shown in the drawings. The tangent position (contact position) C between the drive roller 4 and the driven roller 5 of the entrance roller 2, and the tangent position (contact position) D between the drive roller 6 and the driven roller 7 of the exit roller 3 are as follows. The heights of the tangent positions C and D and the upper surface of the guide plate 8 are aligned. That is, the driving rollers 4 and 6 are made of hard resin with excellent lubricity, whereas the driven rollers 5 and 7 are made of rubber with excellent elasticity and frictional force, so that the thickness of the seaweed A sandwiched between them at the tangent positions C and D is absorbed. As a result, the height levels of the tangent positions C and D are aligned with the height level of the upper surface of the guide plate 8 that guides the seaweed A from below. The roller-to-roller conveying device 1 is as described above.

[0021] Regarding signboard 8: Next, the guide plate 8 will be described. The guide plate 8 serves as an inter-roller guide plate to guide the conveyed seaweed A from below at a front-rear distance B. That is, the guide plate 8 linearly guides the seaweed A transported through the front-to-rear gap B from tangent position C between the driving roller 4 and driven roller 5 of the entrance rollers 2 to tangent position D between the driving roller 6 and driven roller 7 of the exit rollers 3. The seaweed A is placed on the upper surface and transported along the upper surface, thereby guiding the seaweed A so that it is sandwiched linearly at the tangent position D. The guide plate 8 is flat and is disposed horizontally between the entrance roller 2 and the exit roller 3 at a height level that allows it to come into contact with the back side of the seaweed A being transported. Its front-to-back length is slightly smaller than the front-to-back distance B, and its left-to-right width is larger than the width of the seaweed A. The above is the information regarding signboard 8.

[0022] Regarding the suction unit 20 Next, the suction unit 20 will be described. The suction unit 20 is attached to the guide plate 8. That is, the suction unit 20 is incorporated in a position close to the outlet roller 3 of the guide plate 8, and its suction holes 21 open flush with the upper surface of the guide plate 8. The suction holes 21 in the illustrated example consist of elongated slits extending from front to back, with two or three suction holes arranged side by side, each with a width of 6 mm or less. Thus, the suction section 20 sucks the seaweed A toward the guide plate 8 and follows the linear clamping of the seaweed A to the tangent position D of the outlet roller 3.

[0023] Further details will be given of such suction unit 20. In the illustrated example, the suction unit 20 is integrally assembled in the guide plate 8, but it is also possible to assemble it separately while being adjacent to the guide plate 8, without relying on such an illustrated example. For example, the guide plate 8 may be divided into left and right halves, and the suction unit 20 may be disposed between them. The suction holes 21 of the suction unit 20 are aligned at the same height as the upper surface of the guide plate 8 and open flush, and suck the conveyed seaweed A toward the guide plate 8 from below by negative pressure. In addition, when the driven roller 7 of the outlet roller 3 is divided into multiple units as in the illustrated example, the same number of suction units 20 are also arranged in front of and below each driven roller 7, respectively.

[0024] A suction fan is used as the suction source of the suction unit 20. The suction power of the suction unit 20 is as follows. As described above, when the exit roller 3 pinches the front end A1 of the seaweed A that has been sucked in by the suction unit 20, the entrance roller 2 pushes out the rear end A2 of the pinched seaweed A. Then, the exit roller 3 pushes out the pinched seaweed A from the front end A1 to the rear end A2 and conveys it. In this way, the seaweed A is pushed out by the entrance rollers 2 and the exit rollers 3 and transported, and at this time, the suction section 20 is required to have a suction force that is not an obstacle to the pushing out or transport. In other words, the suction force of the suction unit 20 is set to be small enough so as not to interfere with the pushing force or conveying force of the inlet rollers 2 and the outlet rollers 3. b. For the same reason, the suction force of the suction portion 20 is set to be greater in the up-down direction and smaller in the left-right and front-rear directions (binding force). c) Furthermore, the suction part 20 is required to have a stronger suction force the further it is from the exit roller 3 and the closer it is to the entrance roller 2. However, this suction force may cause deformation F of the seaweed A, such as floating or curving, so the suction force is set taking this into consideration. d. When the seaweed A is hard, the suction part 20 is required to have a larger suction force. Taking into consideration each of these factors a, b, c, and d, the suction force of the suction part 20 is set so as to satisfy these factors. The shape of the suction hole 21 and the like are also devised. Therefore, for example, a suction fan of type 9GA0412P3H011 manufactured by Sanyo Denki Co., Ltd. is used as the suction fan of the suction unit 20. The shape of the suction holes 21 and the like are the same as the illustrated example. The above suction fan has a static pressure of about 100 Pa to 400 Pa and an air volume of 0.15 m 3 / min~0.6m 3 / min, and its high speed rotation provides powerful suction power. The suction unit 20 is as described above.

[0025] <<About the illustrated example>> An illustrated example is as follows: 1(1), 1(2) and 2(1) show a typical example of the roller-to-roller conveying system for seaweed A according to the present invention. Two driven rollers 7 and two suction units 20 are arranged on the left and right. Fig. 2(2) shows an example where three units are arranged on the left and right. 3(1) and (2) show an example in which the roller-to-roller conveying system for seaweed A according to the present invention is applied to the inspection section conveying. In this example, a light source 16 and a camera 17 of an inspection device 18 are arranged above and below in the front-to-back space B between the entrance roller 2 and the exit roller 3. The light source 16 illuminates the seaweed A being conveyed, and the camera 17 receives the illuminated light L from the light source 16 through the seaweed A. Based on the received light data, for example, inspection and discrimination of foreign matter attached to the seaweed A are performed. The guide plate 8 has a gap G formed therein for the illumination light L to pass through. In addition, in Figs. 1 and 3, reference numeral 9 denotes a round belt conveying device (V-belt conveyor, string belt conveyor), which conveys seaweed A before and after the inter-roller conveying device 1 according to the present invention. That is, the seaweed A is placed and transported on an endless round belt 12 wound between roller 10 and entrance roller 2, and between exit roller 3 and roller 11. The round belts 12 are arranged at a constant left-right pitch that is narrower than the left-right width of the seaweed A. The entrance rollers 2 and exit rollers 3 are also those of the inter-roller transport device 1. The illustrated example is as above.

[0026] 《Effect, etc.》 The roller-to-roller conveying system for seaweed A according to the present invention is configured as described above. (1) The roller-to-roller conveying device 1 conveys and delivers the seaweed A horizontally from the entrance rollers 2 at the front to the exit rollers 3 at the rear with a front-to-rear gap B. The entrance rollers 2 have a driving roller 4 and a driven roller 5 at the top and bottom, and the exit rollers 3 also have a driving roller 6 and a driven roller 7 at the top and bottom (see Figure 1). The illustrated driven roller 5 is divided into a plurality of rollers arranged on the left and right (see FIG. 1(2) and FIG. 2(2)).

[0027] (2) The front-to-rear distance B between the entrance roller 2 and the exit roller 3 is less than the length of the seaweed A. Thus, when the exit roller 3 pinches the front end A1 of the seaweed A that has been sucked in by the suction unit 20, the entrance roller 2 pushes out the rear end A2 of the seaweed A that it had pinched (see FIG. 2(1)). Then, the exit rollers 3 push and transport the sandwiched seaweed A from the front end A1 to the rear end A2.

[0028] (3) The roller-to-roller conveying system for seaweed A according to the present invention includes a guide plate 8 and a suction unit 20 with respect to the roller-to-roller conveying device 1. That is, the device is provided with an inter-roller guide plate 8 that guides the conveyed seaweed A from below at a front-rear distance B, and a suction unit 20 attached to the guide plate 8 (see Figs. 1 and 2).

[0029] (4) First, the guide plate 8 guides the seaweed A linearly from the tangent position C between the drive roller 4 and the driven roller 5 of the entrance rollers 2 to the tangent position D between the drive roller 6 and the driven roller 7 of the exit rollers 3 (see FIG. 2 (1)).

[0030] (5) The suction section 20 is incorporated in the guide plate 8 at a position close to the outlet roller 3, and its suction hole 21 opens flush with the upper surface of the guide plate 8 (see Figure 1(2) and Figure 2(2)). In the illustrated example, the suction sections 20 are arranged in front of and below the multiple driven rollers 7 that are arranged on the left and right sides of the outlet roller 3 (see Figure 1(2) and Figure 2(2)).

[0031] (6) Thus, the suction section 20 sucks the seaweed A toward the guide plate 8, thereby following up the linear clamping of the seaweed A to the tangent position D of the exit roller 3 (see Figure 1(1) and Figure 2(1)). That is, as described in the above item (4), the guide plate 8 guides the seaweed A, which is placed on it and transported, linearly from below toward the tangent position D of the exit roller 3. The suction unit 20 sucks the seaweed A toward the lower guide plate 8 so that it does not leave the guide of the guide plate 8 and fall off. In this way, the guide plate 8 is supported and followed by the suction part 20, thereby performing the intended guide function for the seaweed A. As a result, the seaweed A is sandwiched at the tangential position D without resistance, without hitting the driven roller 7 of the outlet roller 3.

[0032] (7) The roller-to-roller conveying system for seaweed A according to the present invention functions as follows. With this system, first, the seaweed A is smoothly sandwiched between the exit rollers 3 of the roller-to-roller conveying device 1. The seaweed A conveyed through the front-rear gap B is prevented from curving, floating, flapping, and other deformations F (see the conventional example in Fig. 5(1)). This prevents defects E such as bending, breakage, and clogging (see the conventional example in Fig. 5(2)).

[0033] (8) The inter-roller conveying system for seaweed A according to the present invention has a simple configuration in which the suction unit 20 is incorporated into the guide plate 8 of the inter-roller conveying device 1, and is easy to maintain, repair, and manage.

[0034] (9) In the inspection section, a light source 16 and a camera 17 of an inspection device 18 are disposed above and below each other, and a gap G for passing the irradiated light L is formed in the guide plate 8. The roller-to-roller conveying system for seaweed A according to the present invention can be applied to such conveyance through the inspection section without any problems. That is, the suction unit 20 can be incorporated into the guide plate 8 near the exit roller 3 without any problems.

[0035] (10) Furthermore, by applying the roller-to-roller conveying system for seaweed A according to the present invention, the roller-to-roller conveying device 1 can be used in place of the existing round belt conveying device 9. It is expected that the use of the roller-to-roller conveying device 1, which does not require periodic replacement of the round belts, will become more widespread. The effects etc. are as described above. [Explanation of symbols]
