Description

[Technical Field]

[0001] The present invention relates to a suction and removal structure for protective paper for flat nori bundles used in the nori production process, that is, a structure for sucking and removing protective paper for flat nori bundles without folding it from its paper box. [Background technology]

[0002] 《Technical background》 In the production process of nori (dried nori), after the pre-processing of picking raw nori, washing with water, papering, dehydrating, and drying, the post-processing of inspection, counting, accumulation (folding), and bundling is carried out before the nori is produced and shipped. In a subsequent process, the dried and inspected flat seaweed is counted and accumulated into bundles of, for example, 10 sheets, and then typically folded in half, tied, and shipped. In contrast to this conventional example 1 (representative example), conventional example 2, in which the nori bundles are not folded or bundled, but are simply bundled and shipped as flat nori, is also becoming more common due to market needs. Conventional example 2, in which the nori bundles are bundled and shipped in bundles of 50 or 100 sheets, has also recently become more common. That is, the produced and shipped nori is often subjected to secondary drying and secondary processing such as roasted nori and seasoned nori. In this case, in the conventional example 1 where the nori was folded and bound as described above, the binding is untied and the folds are straightened out again, and the nori is dried and processed as the original flat nori. In contrast, in order to avoid the hassle of stretching, many conventional methods2 are used to bundle and ship the flat nori seaweed as is. [Prior art documents] [Patent documents]

[0003] As a conventional example 2 of bundling and shipping flat nori seaweed without folding it, for example, the following Patent Documents 1 and 2 are listed. [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-101809 [Patent Document 2] Japanese Patent Application Laid-Open No. 2006-101810 Summary of the Invention [Problem to be solved by the invention]

[0004] <<Prior Art>> In the case of Conventional Example 2, protective paper was often used to protect the bundle of flat laver. The protective paper was covered and wrapped around the entire bundle. As shown in (2) to (4) of Figure 5, protective paper P was used to prevent damage to the flat nori seaweed bundle N when it was tied up with the tie band T, during subsequent handling, during distribution, etc. As described above, the protective paper P used in Conventional Example 2 is an extremely thin rectangular sheet, and many sheets are stored in a paper box H (see also Fig. 3(5) and Fig. 4, which will be described later). When bundling, one sheet is taken out and supplied, and then wrapped around the flat nori seaweed bundle N. The removal of the protective paper P from the paper box H was automated and systematized using a suction removal mechanism. As part of the bundling line, the suction removal mechanism separates and removes the topmost sheet of protective paper P from the paper box by suction, and supplies it to the nori seaweed bundle N, which is then wrapped around it and bound.

[0005] 《Problems》 Incidentally, with regard to the conventional example 2 shipped as a flat laver bundle N, the following problems have been pointed out regarding the suction and removal structure of the protective paper P. It often happens that not only the topmost protective sheet P in the paper box to be sucked and separated, but also the lower protective sheets P are sucked in. Because the protective paper P' is extremely thin, the suction reaches the lower protective paper P in the paper box, and the lower protective paper P often sticks together and is taken out and supplied individually or in multiples. Even if the lower protective paper P is not taken out, it may become wrinkled. In the conventional suction take-out structure, such troubles have been a problem when the protective paper P is taken out and supplied.

[0006] About the present invention The suction and removal structure for protecting a flat seaweed bundle of the present invention has been made in consideration of the above-mentioned circumstances and to solve the above-mentioned problems. The present invention aims to provide a device for suction and removal of flat seaweed bundle protective paper that, first, can reliably remove only the topmost sheet, and second, thereby preventing the occurrence of problems. [Means for solving the problem]

[0007] <<About each claim>> The technical means of the present invention to solve such problems are as follows, as set forth in the claims. Regarding claim 1, the following applies: The suction and removal structure for flat nori seaweed bundle protective paper of claim 1 is used in the nori seaweed production process, and sucks and removes the topmost sheet of extremely thin rectangular flat nori seaweed bundle protective paper from a paper box and supplies it. The device has a plate portion, a storage portion provided at an end of the plate portion, and a suction portion disposed within the storage portion. The plate portion is placed in contact with the uppermost protective paper surface inside the paper box. The storage section is disposed and used at a distance D from the longitudinal edge of the protective paper, and is disposed and used with a step distance A between the outer portion of the storage section and the surface of the protective paper. The suction part is characterized in that it is used by being disposed with a vertical height gap C between its suction surface and the protective paper surface.

[0008] In the suction removal structure for the flat seaweed bundle protective paper of claim 2, in claim 1, the suction section forms a suction space S at a height interval C by suction, and while sucking up, the suction also spreads toward the longitudinal edge of the protective paper through the step interval A. The protective paper is abutted and pressed by the plate portion side, and is sucked up and deformed from the sucking space S side toward the longitudinal edge, and separated from the underlying protective paper. Thus, the uppermost protective paper can be separated from the lower protective papers and taken out from the paper box. The structure for suction and removal of a protective paper for a flat laver bundle according to claim 3 is characterized in that in claim 2, the height interval C is a vertical interval equal to or greater than the step interval A.

[0009] The structure for suction and removal of a flat laver bundle protective paper according to claim 4 is characterized in that, in claim 2, the storage section and the suction section are provided at both ends of the plate section, respectively. The suction and removal structure for the flat seaweed bundle protective paper of claim 5 is characterized in that, in claim 2, the plate portion is approximately H-shaped or rectangular along the longitudinal direction of the protective paper, and the storage portion is a cylindrical shape with an open bottom. The suction and removal structure for a flat laver bundle protective paper of claim 6 is characterized in that in claim 2, the protective paper has dimensions of 170 mm to 280 mm x 400 mm to 650 mm and a paper thickness of 0.02 mm to 0.1 mm. The suction and removal structure for flat seaweed bundle protective paper of claim 7 is characterized in that, in claim 6, the gap distance D is 30 mm to 150 mm, the step interval A is 1 mm to 4 mm, and the height interval C is 4 mm to 10 mm.

[0010] <About the effects> The present invention comprises such means and is as follows: (1) The suction and removal structure of the flat laver bundle protective paper of the present invention is made up of a combination of a plate section, a storage section, a suction section, etc. (2) Then, it is dropped onto the top protective paper inside the paper box and used. (3) When in use, the plate portion is placed against the topmost protective paper. The storage section is disposed at a distance D from the longitudinal edge of the protective paper, and a step distance A is provided between the outer portion of the storage section and the protective paper. The protective paper is disposed with a height gap C between the suction portion disposed in the storage portion and the protective paper. (4) Then, due to the suction of the suction unit, a suction space S is formed directly below at a height interval C, and suction is performed. At the same time, the suction spreads toward the longitudinal edge of the protective paper via the step interval A. In other words, it spreads correspondingly over the interval distance D. (5) The protective paper is then abutted and pressed by the plate portion on the one hand, and is sucked up and deformed from the suction space S side toward the longitudinal edge on the other hand. (6) As the protective paper is sucked up and deformed in this way, it separates from the underlying protective paper immediately below it. (7) Therefore, when the suction take-out structure is raised, only the topmost protective paper is taken out by the suction of the suction part. That is, the uppermost protective paper is partially separated from the lower protective paper immediately below it by the suction deformation, and is therefore completely and securely separated from the lower protective paper, and is thus removed from the paper box. (8) The removed protective paper is fed to a bundle of flat nori seaweed. [Effects of the Invention]

[0011] First effect First, you can be sure to remove only the top card. The suction and removal structure for the flat seaweed bundle protective paper of the present invention employs a combination of a predetermined plate section, storage section, suction section, etc., so that only one top protective paper can be separated from the lower protective papers, sucked out from the paper box, and supplied. Although the protective paper is extremely thin, it does not cause any problems when picking up one sheet at a time, as in the conventional example of this type described above, and allows for reliable picking up of one sheet at a time.

[0012] Second Effect Secondly, it also prevents problems from occurring. As described above, the suction take-out structure for the flat laver bundle protective paper of the present invention can reliably take out and supply only the topmost sheet from the paper box. This prevents the lower protective sheets from being sucked in and supplied, as in the conventional example described above. It also prevents the lower protective sheets from being taken out and supplied one or more at a time, or from becoming wrinkled. Thus, the effects of the present invention are remarkable and significant. [Brief explanation of the drawings]

[0014] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Overview of the Invention The outline of the present invention is as follows. The laver bundle protective paper suction and take-out structure 1 of the present invention is used in the laver production process to suck out and supply the topmost sheet of ultra-thin rectangular laver bundle protective paper P from a paper box H. The device has a plate portion 2 , a storage portion 3 provided at an end of the plate portion 2 , and a suction portion 4 arranged within the storage portion 3 . The plate portion 2 is used by being placed in contact with the surface of the uppermost protective paper P inside the paper box H. The storage section 3 is disposed and used at a distance D from the longitudinal edge of the protective sheet P, and at the same time, a step distance A is provided between the outer portion of the storage section 3 and the surface of the protective sheet P. The suction unit 4 is used by being disposed with a vertical height gap C between its suction surface and the surface of the protective paper P. The present invention has been outlined above, and will now be described in detail.

[0015] <<About the line configuration, etc.>> First, with reference to FIG. 3(5), the line configuration of the binding machine 5 and the suction take-out structure 1 will be described. The flat seaweed bundles N are counted and stacked into bundles of 50 or 100 sheets, etc., without being folded, from the previous counting and stacking process and then supplied (see (2) in Figure 5). A single flat seaweed sheet is approximately 210 mm (up to 230 mm, or even 275 mm) long and 190 mm (up to 200 mm) wide, and is in the form of a thin, roughly rectangular sheet. The conveyor 6 then carries the nori seaweed bundles N one by one and transports them forward. The conveyor 6 is, for example, a string conveyor, and the lateral distance between the two strings is narrower than the lateral width of the nori seaweed bundles N. The conveyor 6 is disposed at least up to the bottom of the binding machine 5, and the suction take-out structure 1 is disposed just before the binding machine 5. The suction take-out structure 1 supplies and covers the flat nori seaweed bundle N that has been stopped from being conveyed with a protective paper P. The laver bundle N covered with the protective paper P is stopped on the press plate 7, and then placed on the press plate 7, raised, and pressed. The compressed, wrapped, and covered flat seaweed bundle N (see (3) of Figure 5) is bound with binding bands T by a binding machine 5 (see (4) of Figure 5) and then lowered. The bound flat seaweed bundle N with the protective paper P is then shipped. The above is the line for the binding machine 5 and the suction removal structure 1.

[0016] About the protective paper P Next, the protective paper P will be described with reference to FIG. 3(5), FIG. 4, FIG. 5, etc. The protective paper P protects the flat nori seaweed bundle N from contact during bundling and fastening with the binding band T, subsequent handling, and distribution. The thickness is approximately 0.02 to 0.1 mm, for example, extremely thin paper of approximately 0.04 mm, typically paperback paper. The dimensions are approximately 170 to 280 mm x 400 to 650 mm, for example, a rectangular strip of approximately 205 mm x 470 mm. Note that the nori seaweed bundle N does not have to be completely rolled up. A large number of protective papers P are stacked and stored in a box-shaped paper box H with an open top. In FIG. 3(5), 6' is a conveyor for the paper box. The above is the information regarding protective paper P.

[0017] <<Outline of Suction Extraction Structure 1>> Next, the outline of the suction take-out structure 1 will be described with reference to FIG. 2, FIG. 3(5), FIG. 4, and the like. The suction take-out structure 1 takes out the topmost protective paper P from the paper box H as a suction separation target by suction, and supplies it to the flat nori seaweed bundle N. The laver is then raised and lowered by the attached lifting mechanism 8. As a result, the laver is passed through the steps of (1) in Fig. 4, before the laver is sucked out, (2) after the laver is lowered, (3) during the laver is sucked out, and (4) the laver is lowered to the laver bundle N and supplied to it. The lifting mechanism 8 includes a vertical conveyor, a drive slide, a guide shaft, a free slide, a coupling machine, a motor, and the like, as shown in FIG. 3(5), for example. The suction take-out structure 1 includes a plate portion 2, a storage portion 3, a suction portion 4, and the like. The outline of the suction extraction structure 1 is as described above.

[0018] 《Board part 2》 The plate portion 2 of the suction take-out structure 1 will be described with reference to FIGS. 2 and 3. FIG. The plate portion 2 is made of, for example, an iron plate, and when used with the protective paper P, it forms, for example, an approximately H-shape (example in Figure 2) or a rectangle (example in Figures 3(1) to (4)) along the longitudinal direction of the protective paper P. When in use, i.e., when removing by suction, the plate portion 2 is lowered and placed in contact with the surface of the uppermost protective paper P in the paper box H. Thus, based on its weight, it exerts a pressing force on the protective paper P, pressing the central area of ​​the protective paper P immovably. In this way, the plate portion 2 has a shape and area sufficient to press the rectangular strip-shaped protective paper P firmly against the plate portion. The above is the case for plate section 2.

[0019] Storage section 3 The storage section 3 of the suction and take-out structure 1 will be described with reference to FIGS. The storage section 3 is in the shape of a cylinder with a top that is open at the bottom, and is provided at the end of the plate section 2. For example, it is formed integrally with the plate section 2 by bending it. The storage section 3 in each example of Figures 2, 3 (1), (2), and (3), etc., is a square cylindrical shape, and two are provided on each end of the left and right sides of the plate section 2, for a total of four. 1, 2, 3(1) and 3(3), the storage section 3 is provided at each corner position on both the left and right ends of the board section 2. The storage section 3 in the example of FIG. 3(2) is provided at an inner position, slightly spaced from each corner on both the left and right ends of the board section 2. The storage section 3 in the examples of Figures 1, 2, 3(1) and 3(2) is attached to and connected to the plate section 2. The storage section 3 in the example of Figure 3(3) is provided inside the plate section 2. The storage sections 3 in the example of FIG. 3(4) are long and cylindrical, and two in total are provided along both the left and right ends of the plate section 2.

[0020] When in use, the storage section 3 is lowered and positioned at a distance D from the left and right edges of the rectangular band-shaped protective paper P in the longitudinal direction as shown in the figure. The storage section 3 is also positioned at a distance D from the inner edge of the storage section 3. The gap distance D is a distance necessary and sufficient for the suction unit 4 stored in the storage unit 3 to suck up and deform the uppermost protective paper P in the paper box H as intended when in use. A gap distance of 30 mm to 150 mm enables sucking up and deformation, but is set to, for example, 90 mm to 110 mm. First, as will be described later, a gap A between the uppermost protective sheet P and the outer portion of the storage section 3 is provided. Secondly, in consideration of the spacing distance D between the storage sections 3, the shape and area of ​​the plate section 2 are also set in relation to the protective paper P. Thirdly, W in the figure is the dimension of the storage section 3 and the suction section 4, and is set wider as the thickness of the protective paper P increases. For example, when the paper thickness is 0.04 mm, it is set to about 25 mm. The above is the description of storage section 3.

[0021] 《Suction part 4》 The suction section 4 of the suction take-out structure 1 will be described with reference to Figs. 1, 2, 3(1) to 3(4), and so on. The suction units 4 are respectively arranged in, for example, four storage units 3 provided at the end of the plate unit 2 as described above. Each has, for example, a short cylindrical shape, and is fitted and stored in the upper part of each storage unit 3. For the suction, commercially available and well-known suction structures and adsorption structures can be used, such as Bernoulli grippers, vacuum pads, suction pads, suckers, and the like. The suction unit 4 is disposed with a vertical gap C between the lower suction surface and the surface of the uppermost protective sheet P. This height interval C is set to a vertical interval that allows the uppermost protective paper P in the paper box H to be sucked up and deformed as desired during use. This can be between 4 mm and 10 mm, but it depends on the thickness of the protective paper P. For example, if the thickness is 0.04 mm, it should be about 4 mm.

[0022] The height interval C is set to a vertical interval equal to or greater than the step interval A of the storage section 3. That is, the storage section 3 is cylindrical with a top as described above, but the inner part is, for example, integrally formed and connected to the plate section 2, while the outer part is used with an upper and lower step gap A between it and the surface of the topmost protective paper P inside the paper box H. In order to enable the uppermost protective sheet P, particularly the protective sheet P at the interval D, to be sucked up and deformed as desired, a step interval A of 1 mm to 4 mm is required. The step interval A specifically depends on the thickness of the protective paper P, and is set wider as the paper thickness increases. For example, when the paper thickness is 0.04 mm, the step interval A is set to about 1.5 mm to 2 mm. The height interval C of the suction section 4 is set to be equal to or greater than the step interval A of the storage section 3. This makes it possible to suck up and deform the uppermost protective paper P in the paper box H as desired when in use.

[0023] Now, the suction sections 4 at both ends of the plate section 2 that is being lowered and used form suction spaces S at a height interval C directly below, and as they suck up, the suction spreads through the step interval A toward the longitudinal edge of the uppermost protective paper P. In other words, the suction spreads correspondingly over the interval distance D. Therefore, the uppermost protective paper P is abutted and pressed from above on the plate portion 2 side, and is sucked up and deformed upward from the suction space S side toward the longitudinal end edge, and separated from the lower protective paper P. As a result, when the entire suction removal structure 1 is raised from its lowered state, it is possible to separate only the top protective paper P from the lower protective paper P' and remove it from the paper box H. Since the protective paper P is separated from the lower protective paper P' as described above, the entire protective paper P is also separated from the lower protective paper P' and removed. The suction unit 4 is as described above.

[0024] 《Effect, etc.》 The present invention is configured as described above, and therefore, the following applies. (1) The suction and removal structure 1 for the flat laver bundle protective paper P of the present invention is the first to combine a plate portion 2, a storage portion 3, and a suction portion 4. The storage portion 3 is typically provided at both ends of the plate portion 2.

[0025] (2) The suction removal structure 1 is then lowered onto the uppermost protective paper P in the paper box H, which is the object of suction removal, and used (see (1) and (2) in Figure 4).

[0026] (3) When in use, the plate portion 2 is placed in contact with the uppermost protective paper P (see Figs. 1, 2, and 4(2)). Each storage section 3 is disposed at a distance D from the longitudinal edge of the protective sheet P. Also, each storage section 3 is disposed with a vertical step distance A between its outer portion and the protective sheet P (see FIG. 1). The suction units 4 disposed in the respective storage units 3 are used with a vertical height gap C between them and the protective paper P (see FIG. 1).

[0027] (4) Then, by the suction of each suction unit 4, suction spaces S are formed directly below at a height interval C, and suction is performed. At the same time, suction spreads toward the longitudinal edge of the protective paper P via the step interval A (see Figure 1). In other words, suction spreads correspondingly over the interval distance D.

[0028] (5) Therefore, the uppermost protective paper P is abutted and pressed at its center by the plate portion 2 on the one hand, and is sucked up and deformed from the suction space S side toward its longitudinal edge on the other hand (see (1) and (2) in Figure 1).

[0029] (6) In this way, the protective paper P is sucked up and deformed toward the longitudinal edge, and is separated from the part directly below it. The protective paper P' below the part directly below it is separated from the part directly below it (see Figure 1 (2)).

[0030] (7) Therefore, when the suction take-out structure 1 is raised from its previous lowered state, only the uppermost protective sheet P is taken out together with the suction take-out structure 1 by the suction of each suction section 4. That is, the uppermost protective sheet P is partially separated from the protective sheet P' immediately below it by the above-mentioned suction deformation, and is therefore completely and securely separated from the lower protective sheets P'. As a result, only one sheet can be taken out from the paper box H (see (3) in Figure 4).

[0031] (8) The single sheet of protective paper P thus taken out is supplied to the flat seaweed bundle N and covered therewith (see (4) in Figure 4). [Explanation of symbols]
