Description

  The present invention relates to a seedling transplanting continuous assembling pot used for raising seedlings and transplanting of crops such as vegetables and flower buds, and a method for producing the same.

  This kind of continuous assembly pot for transplanting seedlings is generally a continuous body in which square or hexagonal tubular individual pots formed by spreading a thin film such as paper or paper are connected by connecting pieces. In addition, the continuums are superposed and the superposed continuums are adhered to each other with a water-soluble adhesive (for example, see Patent Document 1). According to such a continuous collection pot body for transplanting seedlings, it appears as a pressed state at the time of storage, appears in a state where a large number of individual pot bodies are densely gathered in a honeycomb shape by being expanded at the time of use, and is grown in individual pot bodies Numerous seedlings can be intensively grown by filling the soil and sowing it. In addition, since this water-soluble adhesive degenerates by irrigation at the time of raising seedlings, this continuous assembly pot body can be pulled out in a row by separating the overlapped continuous bodies by pulling one end after raising seedlings for a predetermined number of days. Thus, for example, using a grounding type simple transplanter as described in Patent Document 2, seedlings can be planted efficiently.

  By the way, according to the above-mentioned conventional general continuous collecting bowl (hexagonal cylindrical shape), the length of the connecting piece is set to be equal to the width of one side face of the individual pot, When trying to plant seedlings continuously using a simple transplanter as described in Patent Document 2, the inter-strain interval is limited by the length of the connecting piece, and depending on the type of seedling crop, the inter-strain interval is too narrow. In some cases, it is necessary to give up its use.

Therefore, for example, in Patent Document 3, an extended portion longer than the width of one side surface of the individual bowl body is provided on the connecting piece, and the extended portion is folded and adhered to each other with a water-soluble adhesive. Disclosed is a continuous assembly pot body attached to the side surface of the individual pot body on the rear side with a water-soluble adhesive, and Patent Document 4 provides a connection piece or individual pot body with a cut in a predetermined shape to connect A continuous assemblage body in which a piece can be extended through the cut is disclosed.

  However, according to the continuous assembly pot disclosed in Patent Document 3, the penetration of irrigation into the folded portion of the increased portion of the connecting piece is insufficient, the degeneration of the water-soluble adhesive in the raising seedling is insufficient, There is a problem in that the folded portion of the connecting piece does not smoothly separate and extend at the time of transplantation, and the length of the connecting piece, that is, the interval between strains is likely to vary. In addition to the fact that the extended part of the connecting piece must be folded and adhered to each other with an adhesive, this folded part must be adhered to the individual bowl, making the production cumbersome and making the production cost There was also a problem that the price became high. On the other hand, according to the continuous assembly pot disclosed in Patent Document 4, there is a problem that when the individual pots are pulled out in a row for transplanting work, stress concentrates on the edge of the cut portion and is easy to cut. .

  The present invention has been made in view of the above-described conventional problems, and the problem is that the connecting piece can be extended without folding the increased portion or making a cut, thereby changing the inter-strain interval. An object of the present invention is to provide a continuous collection pot for raising seedling transplants that can be handled safely and reliably and contribute to cost reduction and a method for producing the same.

  In order to solve the above-mentioned problems, the continuous seedling transplanting pot for transplanting seedlings according to the present invention connects square or hexagonal cylindrical individual pots with connecting pieces formed by developing a thin film such as paper or paper. In the continuous collection pot body for transplanting seedlings in which the continuous bodies are overlapped with each other and the overlapped continuous bodies are adhered with a water-soluble adhesive, the connecting pieces and the individual pots Forming the body independently, and arranging the connecting pieces alternately in a staggered manner on both sides of the juxtaposed individual pot bodies, and connecting both end portions of the connecting pieces to the side surfaces of the adjacent individual pot bodies. While sticking with a water-soluble adhesive, one side of each connection piece was joined to the side surface of the individual bowl with a water-soluble adhesive.

  In the continuous gathering pot for transplanting seedlings constructed in this way, by appropriately selecting the sticking positions (sticking with a water-insoluble adhesive) at both ends of the connecting piece to the side surface of the adjacent individual pots, When assembling hexagonal cylindrical individual pots, the length of the connecting piece can be freely changed within a range of 1 to 7 times the width of one side of the individual pots, When assembling the individual pot bodies, the length of the connecting piece can be freely changed within a range of 1 to 5 times the width of one side surface of the individual pot bodies. In addition, the connecting pieces are alternately arranged in a staggered pattern on both sides of the continuous body, and are only attached to the side surface of the individual pot body without folding into multiple layers. Is sufficiently degenerated, and the connecting piece is smoothly separated and stretched during transplantation.

Moreover, the manufacturing method of the continuous collection pot body for raising seedling transplants according to the present invention includes a first step of pasting both side ends of the strip-shaped thin film with a water-insoluble adhesive to form a cylindrical individual pot body, A connecting piece is alternately arranged in a staggered pattern on both sides of the individual pots arranged in parallel by a predetermined number, and both ends of the connecting piece are attached to the side surfaces of the adjacent individual pots with a water-insoluble adhesive. , A second step in which one side of the connecting piece is attached to the side surface of the individual bowl with a water-soluble adhesive to form a continuous body, and the continuous body is overlaid and pasted with a water-soluble adhesive. And a third step of wearing.
In the method for producing a continuous collecting pot for raising seedlings transplanted in this way, it is not necessary to fold the increased portion of the connecting piece, so the process is simplified.

  According to the continuous collecting pot for raising seedlings according to the present invention, the water-soluble adhesive is sufficiently degenerated by irrigation during raising seedlings. Can be transplanted. In addition, it is not necessary to fold the connecting pieces into multiple layers, and the connecting pieces of the required length are simply attached to the side surfaces of the individual pots, so that the water-soluble adhesive is sufficiently degraded by irrigation during raising seedlings. The connecting pieces can be separated and extended smoothly, and a desired inter-strain interval can be secured stably.

  Moreover, according to the manufacturing method of the continuous collection pot for raising seedling transplants concerning this invention, since it is not necessary to fold a connection piece in multiple layers, a process is simplified and manufacturing cost reduces.

  The best mode for carrying out the present invention will be described below with reference to the accompanying drawings.

  1 and 2 show a continuous collection pot for raising seedlings as a first embodiment of the present invention. In the first embodiment, a large number of hexagonal tubular individual bowls 1 are assembled, and each individual bowl 1 is connected by a connecting piece 2. A series of continuous bodies 3 formed by the individual pot bodies 1 and the connecting pieces 2 are overlapped via a water-soluble adhesive so that the individual pot bodies 1 are shifted by 1/2 pitch. A continuous collecting bowl 4 is formed in which are closely gathered. In FIGS. 1 and 2, for the sake of understanding, the distance between the individual pot body 1 and the connecting piece 2 and the distance between the layers of the continuous body 3 are shown, but there is actually no gap between them. The water-soluble adhesive which abbreviates is interposed.

  The individual bowl 1 is formed in a cylindrical shape by sticking the overlapping portions of both ends of one thin film 5 with a water-insoluble adhesive (sticking portion 6), and one side surface (six It is arranged with an interval equivalent to the width of one side of the square. On the other hand, the connecting pieces 2 are formed separately from the individual pot bodies 1 and are alternately arranged in a staggered manner on both sides of the individual pot bodies 1 arranged in parallel. Here, both end portions of each connecting piece 2 are side surfaces 1a and 1a that are the most separated between adjacent individual bowl bodies 1, and are attached to a water-insoluble adhesive at a site close to the inner ridge angle. Are attached (attachment part 7). Therefore, here, each connecting piece 2 has a length that is approximately five times the width of one side surface of the individual pot 1.

  Each continuous body 3 is formed by joining each connecting piece 2 to the side surface of the individual pot body 1 with a water-soluble adhesive (not shown). Each continuum 3 is also overlapped by reversing (turning) 180 degrees for each predetermined length. In this case, a folded piece 8 longer than the connecting piece 2 having the predetermined length is required at the connecting portion between the continuous bodies 3. Therefore, in the present embodiment, as shown in FIGS. 1 and 2, the folded piece 8 is divided into two parts, and one of the divided pieces 8 a is located at the end of the upper continuous body 3. In addition, the other divided piece 8b is provided in the individual pot body 1 positioned at the end of the lower continuous body 3, and both the divided pieces 8a and 8b are connected by the sticking part 9 made of a water-insoluble adhesive. I have to.

  Here, the material type of the thin film 5 is arbitrary, but a material having corrosion resistance is selected at least during the seedling raising period. In general, the seedling period is around 40 days, but in the case of long onions, onions, etc., it is 40 to 90 days or more. Examples of the material having anti-corrosion properties of about 40 days include paper obtained by applying or blending a preservative or bactericide to plant fiber paper, and synthetic fiber paper obtained by blending synthetic fiber with natural pulp. Also, as a grade having anti-corrosion for 40 to 90 days or more, anti-corrosive paper treated with synthetic fiber mixed paper with chemicals to increase wet strength, non-corrosive non-woven sheet, natural Examples include paper obtained by treating pulp with chemicals or paper obtained by treating synthetic fiber mixed paper with antiseptic chemicals such as bactericides.

  The type of the above-mentioned adhesive is also arbitrary, and examples of the water-soluble adhesive include chemical compounds such as polyvinyl alcohol, polyacrylic acid, and polyethylene oxide, or natural products such as gum arabic, glue, and carboxymethyl cellulose. Can be used. In addition, as the water-insoluble adhesive, for example, a chemical composition such as a polyvinyl acetate emulsion, an epoxy resin emulsion, or a hot melt can be used.

  As shown in FIG. 1, the continuous collecting bowl 4 configured in this way is stored and provided in a pressed state as shown in FIG. 2, and when it is stretched in the stacking direction of the continuous body 3 in this state, many The individual pot bodies 1 expand in a honeycomb shape, and a continuous assembly pot body 4 having a predetermined size appears. When raising seedlings, the continuous collection pots 4 are set in a seedling box (not shown) in an expanded state, and each individual pot 1 is filled with cultivated soil and sown. Then, when the seedlings are grown for a predetermined number of days, the water-soluble adhesive between the side surface of the individual pot 1 and the connecting piece 2 and the water-soluble adhesive between the continuous bodies 3 are degenerated by irrigation during the seedling. Therefore, when transplanting after raising seedlings, if one end of the continuum 3 constituting the continuous collecting pot 4 is pulled, the continuum 3 is drawn out in a row as shown in FIG. 3, thereby enabling efficient planting. . In this case, the length of the connecting piece 2 is approximately five times as long as the width of one side surface of the individual pot body 1, and can effectively cope with cultivation of a crop that requires a wide inter-strain interval.

  Here, the said connection piece 2 can be made into various length by changing the position of the sticking part 7 with respect to the adjacent individual pot body 1. FIG. For example, FIG. 4 (the same reference numerals are assigned to the same parts) shows an example in which the length of the connecting piece 2 is approximately 3.5 times the width of one side surface of the individual pot body 1, What is necessary is just to stick the both ends of each connection piece 2 with the water-insoluble adhesive to the intermediate part of the side surfaces 1b and 1b which are spaced apart intermediately between the adjacent individual bowls 1 (sticking part 7). .

  FIG. 5 (same parts are given the same reference numerals) shows an example in which the length of the connecting piece 2 is approximately seven times the width of one side surface of the individual pot body 1. Adhering both ends of the piece 2 with water-insoluble adhesives to the side surfaces 1a and 1a that are the most separated between the adjacent individual bowls 1 and close to the ridge angles that are outside each other. 7), and further, each connecting piece 2 is folded back at the outer edge of the sticking portion 7 as a fulcrum. In the example shown in FIG. 5, when each connecting piece 2 is not folded back at the sticking portion 7, the length of the connecting piece 7 is approximately 6.5 times the width of one side surface of the individual pot 1. Become.

  Furthermore, in each said embodiment, the both ends of the connection piece 2 are stuck on the position (for example, on the side surface 1a or 1b) used as the line object of the adjacent individual pot 1, and with respect to the adjacent individual pot 1 Although the connecting piece 2 is extended evenly, the connecting piece 2 may be extended non-uniformly with respect to the adjacent individual pots 1. In this case, The length of the connecting piece 2 can be changed more finely within a range of 1 to 7 times the width of one side surface.

  6 and 7 show a continuous collection pot for transplanting seedlings as a second embodiment of the present invention. In the second embodiment, a large number of rectangular tubular individual pots 11 are assembled, and each individual pot 11 is connected by a connecting piece 12. A series of continuous bodies 13 formed by the individual pot bodies 11 and the connecting pieces 12 are overlapped via a water-soluble adhesive so that the individual pot bodies 11 are in a lattice shape. A continuous assembly bowl 14 that is densely assembled is formed. In FIGS. 6 and 7, for the sake of understanding, the distance between the individual pot body 11 and the connecting piece 12 and the distance between the layers of the continuous body 13 are shown with a gap between them. A water-soluble adhesive that stands for is interposed.

  The said individual bowl 11 is formed in the cylinder shape by sticking the overlap part of the both ends of the thin film 15 with the water-insoluble adhesive (adhesion part 16), The one side is adjacent. The individual pot bodies 11 are arranged in close contact with each other and in a lattice shape. On the other hand, as shown in FIG. 7, the connecting piece 12 is formed separately from the individual bowl body 11, and the individual bowl body 11 is arranged in parallel with an interval equivalent to the width of one side surface (one side of the square tube). The individual pot bodies 11 are arranged in a staggered pattern alternately on both sides. Here, both end portions of each connecting piece 12 are adhered (adhering portion 17) with a water-insoluble adhesive at a position most distant from each other between adjacent individual pot bodies 11. Therefore, here, each connecting piece 12 has a length that is approximately five times the width of one side surface of the individual bowl 11.

  Each continuous body 13 joins each connecting piece 12 to the side surface of the individual pot body 11 with a water-soluble adhesive (not shown), and the individual pot bodies 11 overlap with each other as shown in FIG. In addition, each connecting piece 11 is folded back along the side surface of the individual pot body 11 (in the directions of arrows R and R ′), and the space between them is adhered with a water-soluble adhesive. Each continuous body 13 is also overlapped by being reversed (turned) 180 degrees every other sheet. In this case, a folded piece 18 equivalent to the connecting piece 12 having the predetermined length is required at the connecting portion between the continuous bodies 13. Therefore, in the second embodiment, the folded piece 18 is divided into two parts, and the respective divided pieces 18a and 18b are provided on the individual pot bodies 11 located at both ends of the continuous body 13, respectively. 18b is connected by the sticking part 19 by a water-insoluble adhesive.

  As shown in FIG. 6, the continuous assembly bowl 14 configured as described above is stored and provided in a compressed state as in the first embodiment. The individual pot bodies 11 expand in a lattice shape, and a continuous assembly pot body 14 of a predetermined size appears. This continuous assembly pot body 14 is different from the first embodiment in the shape of the individual pot body 11 (square tube shape) and the connection form of the continuous body 13, but the sowing and seedling methods are the same as in the first embodiment. is there. Furthermore, in this 2nd Embodiment, although the length of the connection piece 12 was made into 5 times the width | variety of the one side surface of the individual bowl 11, if it is in the range of 1-5 times the width | variety of the said one side surface, The length of the connecting piece 12 (inter-strain interval) can be arbitrarily set according to the crop to be cultivated.

  FIG. 9 shows one embodiment in the case of industrially producing a continuous assembly bowl 4 in which the hexagonal tubular individual bowls 1 according to the first embodiment are assembled. In this case, A first base paper roll 20 on which a wide thin film (base paper) for individual pots is wound and two second base paper rolls 21 on which a wide thin film (base paper) for connecting pieces are wound are prepared. Then, the base paper 22 drawn out from the first base paper roll 20 is cut into a predetermined number of strip-shaped thin films 24 by a slitter 23 with a predetermined width. These band-like thin films 24 are sequentially guided to a tube-making glue device 25 and a cylinder-making device (molding rod) 26, and the sticking portion 6 is attached to one side edge of each belt-like thin film 24 by the tube-making glue device 25. Is formed into a cylindrical shape by the cylinder making device 26, thereby forming a belt-like cylindrical body 27 having the same cross-sectional size as the individual bowl 1. The belt-like cylinders 27 are sent to the connecting roller 28 in parallel at a predetermined interval (an interval equivalent to the width of one side surface of the individual bowl 1).

  On the other hand, the base papers 29 and 29 drawn out from the two second base paper rolls 21 and 21 are cut by the slitters 30 and 30 into strip-shaped thin films (band-shaped connecting pieces) 31 and 31 having a predetermined width and a predetermined number of sheets. These band-like connecting pieces 31 are sequentially guided to the two connecting piece gluing devices 32 and 33, and the pasting portions 7 are formed on both side edges of each band-like connecting piece 31 by the preceding connecting piece gluing device 32. A water-insoluble adhesive is applied, and a water-soluble adhesive is applied to a portion excluding a predetermined range in the central portion by the subsequent connecting piece gluing device 33 and sent to the connecting roller 28. At this time, the strip-shaped connecting pieces 31 and 31 are alternately arranged on both sides of the continuous body 3 (see FIGS. 1, 4 and 5), that is, the strip-shaped cylindrical body 27 is sandwiched from above and below. Then, the belt-like continuous body 34 having the same cross-sectional shape as that of the continuous body 3 (see FIG. 2) is formed.

  Subsequently, the belt-like continuous body 34 is sequentially guided to the gluing roller 35 and the gluing device 36, and a water-soluble adhesive is applied to the upper surface of the belt-like continuous body 34 by the gluing roller 35. A water-insoluble adhesive forming the sticking part 9 of the folded piece 8 is applied to the end of the belt-like continuous body 34. The belt-like continuous body 34 coated with the adhesive is cut into a predetermined width (corresponding to the height of the individual bowl body 1) by a rotary cutter 37, whereby the continuous body 3 is formed. And this continuous body 3 is reversed 180 degree | times every other sheet | seat by the following inversion machine 38, and it sends to the lamination | stacking bonding apparatus 39, and, thereby, the continuous body 3 mutually carries out lamination bonding via a water-soluble adhesive. The continuous collecting pot 4 is completed.

  Here, although not shown in the drawings, the glue roller 35 is provided with a device for detecting the feed amount of the belt-like continuous body 34, and when a predetermined amount of the belt-like continuous body 34 is fed to the rotary cutter 37, The gluing roller 35 is raised so that the water-soluble adhesive is not applied to the upper surface of the belt-like continuous body 34 by an amount corresponding to the width of the single continuous body 3 (height of the individual bowl 1). . As a result, a predetermined number of continuous bodies 3 are laminated and pasted by the laminating and bonding apparatus 39, and it is possible to take out one by one as the continuous collective pot 4.

  In addition, as shown in FIG. 5, when manufacturing the continuous assembly pot 4 of the aspect which wraps the both ends of each connection piece 2, and sticks it by the sticking part 7, it is in the front | former stage of the connection piece pasting apparatus 32. A step of bending both side portions of the strip-shaped connecting piece 31 is provided.

  On the other hand, the method for industrially manufacturing the continuous assembly bowl 14 in which the rectangular cylindrical individual bowls 11 according to the second embodiment are assembled is basically the same as the processing flow shown in FIG. This will be described below using the reference numerals shown in FIG.

  First, a base paper 22 drawn from the first base paper roll 20 is cut into a strip-like thin film 24 by a slitter 23, a water-insoluble adhesive is applied by a pipe making glue device 25, and the individual pots 11 and A belt-like cylindrical body 27 having the same cross-sectional size is formed. On the other hand, the base papers 29 and 29 drawn from the two second base paper rolls 21 and 21 are cut into strip-like thin films (strip-like connecting pieces) 31 and 31 by slitters 30 and 30, and a water-insoluble adhesive is applied to both side edges thereof. Then, a water-soluble adhesive is applied to each part except the central part. And the said strip | belt-shaped connection pieces 31 and 31 are guide | induced to the connection roller 28 so that the strip | belt-shaped cylinder 27 may be pinched | interposed from the upper and lower sides, and both are connected.

  In the case of producing a continuous assembly bowl 14 in which the rectangular cylindrical individual bowls 11 are assembled, a folding paste applicator, a folding apparatus, and a continuous body forming roller (not shown) are arranged in order after the connecting roller 28.
