Description

[Technical Field]

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

[0002] 《Technical background》 In production and processing lines for dried seaweed (hereinafter simply referred to as "seaweed"), the seaweed is transported and processed in various ways using conveyors such as round belt transporters, flat belt transporters, and roller-to-roller transporters. The roller-to-roller conveying device conveys the seaweed from the entrance roller to the exit roller spaced apart from each other.

[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-to-rear gap B therebetween. The entrance roller 2 has a driving roller 4 and a driven roller 5 arranged above and below, and the exit roller 3 also has a driving 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 out the pinched seaweed A.

[0004] <<Prior Art: Regarding Guide Board 8>> The inter-roller conveying device 1 is provided with a guide plate 8 that guides 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 roller 2 to a tangent position D between the driving roller 6 and the driven roller 7 of the exit roller 3. In the figure, reference numeral 9 denotes a round belt conveying device, which conveys seaweed A before and after the inter-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] Incidentally, the following problems have been pointed out as issues with the conventional inter-roller conveying device 1 for laver A. Problem 1: Occurrence of defects such as bending, damage, and clogging First, it was pointed out that the seaweed A was not smoothly sandwiched between the exit rollers 3, and defects E such as bending, breakage, and clogging often occurred. For example, in the case of seaweed A that has a low moisture content and is fragile, such as seaweed A from a secondary processing line that produces baked seaweed or roasted seaweed, or seaweed A that has a strong flavor, the seaweed A is likely to deviate from the linear guide provided by the guide plate 8 during transport, resulting in bending, floating, flapping, and other deformations F. As shown in Figure 5 (1), the tip A1 of the seaweed A hits the driven roller 7 of the outlet roller 3 and becomes deformed F, which prevents the seaweed A from being smoothly sandwiched at the tangent position D between the driven roller 7 and the driving roller 6, causing it to shift up or down from the tangent position D, resulting in defects and instability. As shown in Figure 5 (2), defects E such as bending, breakage, and clogging of the seaweed A often occurred. (In contrast, as shown in Figure 5(3), when the leading end A1 of the seaweed A hits the lower driving roller 6, the problem 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 upper presser guide plate> Secondly, as a measure to prevent deformation F of the seaweed A at the above-mentioned exit roller 3 and as a measure to prevent malfunction E, a measure 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 was also developed. That is, measures have been taken to install a round belt or a guide plate in front of the exit roller 3 to press down on the conveyed seaweed A from above. However, although this measure was effective to some extent, it was pointed out that maintenance was troublesome. That is, if the seaweed A got stuck between the lower guide plate 8, it was difficult to remove it. Furthermore, it was pointed out that the upper presser round belt required periodic replacement. (Incidentally, reference numeral 13 in Fig. 4 and Fig. 6 denotes an upper presser round belt. This upper presser 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 nori A is pressed down between the upper presser round belt 13 and the round belt 12 of the lower round belt conveyor 9, thereby realizing smooth sandwiching at the tangent position C of the entrance roller 2.)

[0007] Problem 3: Transporting items between inspection areas Thirdly, it was difficult to install the above-mentioned upper pressure round belt and 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-back space B. Therefore, the above-mentioned deformation F and the occurrence of the defect E remained as problems. Therefore, 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 air blowing would cause the seaweed A to flutter, which was a fatal problem. Furthermore, using a round belt conveying device 9 instead of the inter-roller conveying device 1 was also difficult 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 inter-roller conveying device 1 are as 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 circumstances and to solve the problems of the above-mentioned conventional technology. 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.

(3) The roller-to-roller conveying system for seaweed according to the present invention is provided with a guide plate and a suction unit with respect to such a roller-to-roller conveying device. (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 outlet roller, and the suction hole is flush with the top surface of the guide plate. (6) The suction unit sucks the seaweed toward the guide plate, thereby helping to pinch the seaweed in a straight line to the tangent position of the exit roller.

[Effects of the Invention]

[0013] First effect First, the seaweed is smoothly sandwiched between the exit rollers. The nori seaweed conveying system according to the present invention is characterized in that a suction unit is incorporated into the guide plate of the roller conveying device, so that the nori seaweed is guided in a straight line reliably to the tangent position of the exit roller and smoothly sandwiched. Unlike the conventional roller conveying device described above, the conveyed seaweed is prevented from curving, floating, flapping, or other deformations. It also does not shift up or down, causing defects or instability. As a result, problems such as bending, breakage, and clogging do not occur, and the seaweed is smoothly sandwiched at the tangential position between the drive roller and the driven roller of the outlet roller.

[0014] Second Effect Secondly, it is easy to maintain. The laver conveying system according to the present invention is configured by incorporating a suction unit into the guide plate of the roller conveying device. This means that no special maintenance is required, and it is easy to maintain, service, and manage. Unlike the conventional example mentioned above, there is no need for troublesome maintenance. In other words, if the seaweed gets stuck in the upper pressure round belt or the upper pressure guide plate during conveyance, there is no need to take out and remove the jammed seaweed. There is also no need to replace the round belt periodically.

[0015] Third Effect Thirdly, transportation between inspection sections is possible without any problems. In the inspection section, a light source and a camera of the inspection device are arranged above and below between the entrance roller and the exit roller, and a gap is formed in the guide plate to allow the irradiated light to pass through. The laver conveying system according to the present invention can be applied to such inspection zone conveyance 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, which requires the installation of an upper pressure round belt and an upper pressure guide plate. In this way, the effects of the present invention are remarkable and great, as all of the problems that existed in the prior art of this type are solved. [Brief explanation of the drawings]

[0017] The present invention will be described in detail below with reference to FIGS. Overview of the Invention First, the outline of the present invention is as follows. The roller-to-roller conveying system for laver A according to the present invention relates to an inter-roller conveying device 1 that conveys laver A from a front entrance roller 2 to a rear exit roller 3 with a front-to-rear gap B therebetween. The conveying device is provided with an inter-roller guide plate 8 that guides the conveyed seaweed A from below at a front-to-rear interval B, and a suction section 20 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 the 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 side, and follows the seaweed A so that it is pinched linearly to the tangential position D of the outlet roller 3. The outline of the present invention is as above. The present invention will be described in further 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, the Nori A is transported and processed in various ways. 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 for transport. The inter-roller conveying device 1 conveys seaweed A from an entrance roller 2 at the front to an exit roller 3 at the rear, with a front-to-rear gap B. The entrance roller 2 has a driving roller 4 and a driven roller 5 arranged above and below, and the exit roller 3 also has a driving roller 6 and a driven roller 7 arranged above and below.

[0019] A more detailed description will be given of such an inter-roller conveying device 1. The laver 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, roughly sheet. The front-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 nori A to be sucked by the suction section 20, the entrance roller 2 pushes out the rear end A2 of the pinched nori A, and the nori A is then transported by the exit roller 3. The front-to-rear distance B is usually about 130 mm to 200 mm.

[0020] The drive rollers 4 and 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 driven to rotate. 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 accordance with the rotation of the driving rollers 4, 6. In the illustrated example, multiple rollers are arranged in a divided fashion on the left and right. 2(1), the driven rollers 5, 7 are mounted on a fixed bracket K having a vertically long hole H through which the shafts S of the driven rollers 5, 7 are inserted so as to be movable up and down. As a result, the driven rollers 5, 7 are pressed against the driving rollers 4, 6 by their own weight, and are able to sandwich the nori A therebetween. The driven rollers 5, 7 in the illustrated example are thin and roughly top-shaped or wheel-shaped, with two or three or more rollers arranged at intervals in the left-right direction, but they may also be a single straight roller rather than the left-right split type shown in the illustration. 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 tangent positions C and D and the upper surface of guide plate 8 are aligned. That is, drive rollers 4 and 6 are made of hard resin with excellent lubricity, while driven rollers 5 and 7 are made of rubber with excellent elasticity and friction, so the thickness of the seaweed A sandwiched between them at tangent positions C and D is absorbed. As a result, the height levels of the tangent positions C and D and the height level of the upper surface of the guide plate 8 that guides the seaweed A from below are aligned. The roller-to-roller conveying device 1 is as described above.

[0021] <About Signboard 8> Next, the guide plate 8 will be described. The guide plate 8 guides the conveyed seaweed A from below at a front-to-rear distance B as a guide plate between rollers. That is, the guide plate 8 linearly guides the seaweed A conveyed through the front-to-rear distance B from the tangent position C between the driving roller 4 and the driven roller 5 of the entrance roller 2 to the tangent position D between the driving roller 6 and the driven roller 7 of the exit roller 3. The seaweed A is placed on the upper surface and conveyed 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 placed horizontally between the entrance roller 2 and the exit roller 3 at a height level that allows it to contact the back side of the seaweed A being conveyed. 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] <<About 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 into the guide plate 8 at a position closer to the outlet roller 3, and its suction holes 21 are 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 unit 20 sucks the laver A toward the guide plate 8 side, and follows up the linear pinching of the laver A to the tangent position D of the outlet roller 3.

[0023] The suction unit 20 will be described in further detail. In the illustrated example, the suction unit 20 is integrally assembled in the guide plate 8, but it is also possible to incorporate it separately and adjacent to the guide plate 8. 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 flush with the upper surface of the guide plate 8 and are aligned in height, and the conveyed seaweed A is sucked from below onto the guide plate 8 by negative pressure. Furthermore, when the driven roller 7 of the outlet roller 3 is divided into multiple parts as in the illustrated example, the same number of suction sections 20 are also arranged in front of and below each driven roller 7.

[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 nori 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 nori seaweed A. Then, the exit roller 3 pushes out the pinched nori 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 roller 2 and the exit roller 3 and conveyed, and at this time, the suction part 20 is required to have a suction force that is not an obstacle to the pushing out or conveyance. 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 entrance roller 2 or the exit roller 3. b. For the same reason, the suction portion 20 is set to have a greater suction force in the up-down direction and a smaller suction force (binding force) in the left-right and front-rear directions. c) Furthermore, the suction part 20 requires a greater 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 bending, 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 to satisfy these factors. The shape of the suction hole 21 and the like are also devised. Therefore, for example, a 9GA0412P3H011 type 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 in 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 example of the illustration is as follows: 1(1), 1(2) and 2(1) show a typical example of a roller-to-roller conveying system for laver A according to the present invention. Two driven rollers 7 and two suction units 20 are arranged on the left and right. 2(2) of FIG. 2 shows an example in which three are arranged on the left and right. 3(1) and (2) show an example in which the inter-roller conveying system for laver A according to the present invention is applied to the inspection section conveyance. 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. A light source 16 illuminates the seaweed A being conveyed, and a camera 17 receives the irradiated 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. A gap G is formed in the guide plate 8 to allow the irradiated light L to pass through. 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 laver A according to the present invention is configured as described above. (1) The roller-to-roller conveying device 1 horizontally conveys and delivers the seaweed A from the entrance roller 2 at the front to the exit roller 3 at the rear, with a distance B between them. The entrance roller 2 has a driving roller 4 and a driven roller 5 at the top and bottom, and the exit roller 3 also has a driving roller 6 and a driven roller 7 at the top and bottom (see Figure 1). In the illustrated example, a plurality of driven rollers 5 are arranged in a divided manner on the left and right (see FIG. 1(2) and FIG. 2(2)).

[0027] (2) The distance B between the entrance roller 2 and the exit roller 3 is less than the length of the nori A. Therefore, when the exit roller 3 pinches the front end A1 of the nori A that has been sucked in by the suction section 20, the entrance roller 2 pushes out the rear end A2 of the nori A that it had pinched (see (1) in Figure 2). Then, the outlet roller 3 pushes and conveys the sandwiched seaweed A from the front end A1 to the rear end A2.

[0028] (3) The roller-to-roller conveying system for laver 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, it is provided with an inter-roller guide plate 8 that guides the conveyed seaweed A from below at a front-to-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 driving roller 4 and the driven roller 5 of the entrance roller 2 to the tangent position D between the driving roller 6 and the driven roller 7 of the exit roller 3 (see (1) in Figure 2).

[0030] (5) The suction section 20 is incorporated into the guide plate 8 at a position near the outlet roller 3, and its suction holes 21 are 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 on 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 laver A being placed and transported in a straight line from below toward the tangent position D of the exit roller 3. The suction unit 20 sucks the laver A toward the lower guide plate 8 so that it does not separate from 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 fulfilling the intended guide function for the seaweed A. As a result, the seaweed A is sandwiched at the tangential position D without resistance and without hitting the driven roller 7 of the outlet roller 3.

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

[0033] (8) The inter-roller conveying system for laver 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, the light source 16 and the camera 17 of the inspection device 18 are disposed above and below each other, and a gap G is formed in the guide plate 8 to allow the irradiated light L to pass through. The roller-to-roller conveying system for laver A according to the present invention can be applied without any problems to the conveyance through such an inspection section. That is, the suction unit 20 can be incorporated into the guide plate 8 near the exit roller 3 without any problems.
