Description

  TECHNICAL FIELD The present invention relates to a seedling transplanting continuous assemblage body 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 formed by connecting individual pot bodies in a square or hexagonal cylinder shape by connecting pieces formed by developing a thin film such as paper or paper. 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 predetermined shape of cut and connected A continuous assemblage body in which a piece can be extended through the cut is disclosed.

However, according to the continuous assembly pot (hexagonal cylindrical shape) disclosed in Patent Document 3, the penetration of the irrigation into the folded portion of the extended portion of the connecting piece is insufficient, and the degradation of the water-soluble adhesive during raising seedlings is not possible. There has been a problem that the folded portion of the connecting piece does not smoothly separate and extend during transplantation, and the length of the connecting piece, that is, the inter-strain interval tends 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 is concentrated on the edge of the incised portion and it is easy to cut. .

  Next, a second embodiment of the present invention will be described with reference to FIGS. As shown in FIGS. 4 and 5, the continuous collection pot 11 for transplanting seedlings (hereinafter referred to as the continuous collection pot 11) is a collection of individual pot bodies 12 each having a hexagonal cylindrical shape. The pot body 12 includes a connecting piece 13 and folded pieces 14 and 15. Here, the connecting piece 13 is folded back approximately 1/3 width on one side in the width direction of the thin film (left and right direction in FIG. 5), and the folded portion 16 (folded portion) is pasted on the thin film with a water-soluble adhesive. It is what I wore. And in this continuous gathering bowl 11, in the direction where the turned-up part 16 of the connection piece 13 opposes the turned-up part 16 of the opposing connection piece 13, 1/2 pitch (1 pitch is set to the full width of the connection piece 13. A predetermined number of rows are arranged in two rows with a substantially equal spacing.) By adhering both end portions in the width direction of each connecting piece 13 to each opposing connecting piece with a water-insoluble adhesive (attaching portion 17) A series of continuums 18 are formed. Furthermore, in this continuous collective pot 11, the continuous collective pots in which the individual pots 12 are gathered densely by stacking a large number of the continuous elements 18 and sticking them together with a water-soluble adhesive. 11 is formed. 4 and 5, the gap between the connecting piece 13 and the folded pieces 14 and 15 and the gap between the layers of the continuous body 18 are shown, but actually, the water-soluble adhesive is not shown in the gap. An agent is present.

  As shown in FIG. 5, the continuous collecting bowl body 11 is configured such that the folded portions 16 facing each other of the connecting pieces 13, or the other side 21 where the folded portions 16 are not attached to the connecting pieces 13, The non-sticking part formed between the sticking parts 17 and 17 is provided as the individual pot body 12, and this non-sticking part (individual pot body 12) is one side surface of the individual pot body 12 (FIG. Are connected with an interval equivalent to the width of one side of the hexagon shown in FIG. On the other hand, the connecting piece 13 is formed by folding back one side in the width direction of the thin film by approximately 1/3 of the entire width, the folded portions 16 of the facing connecting pieces 13 face each other, and the other connecting pieces 13 are opposed to each other. Arranged in a staggered manner (every 1/2 pitch) so that the sides 21 (the other side of the thin film) face each other. Moreover, the connection piece 13 is crimped | bonded so that a width | variety may become substantially 7 times the width | variety of the one side surface of the individual pot body 11, and the side surface to which the folding | turning part 16 is not stuck is shown in FIG. , And provided substantially as a connecting portion 19 (connecting piece) at the time of planting, which will be described later.

  As described above, the continuum 18 is formed by sticking the connecting pieces 13 arranged in a staggered manner, and is continuously reversed by reversing (turning) a predetermined number of continuums 18 by 180 degrees. The collective pot 11 is formed. In this case, as shown in FIGS. 4 and 5, the folded pieces 14 and 15 having a narrower width than the connecting piece 13 are disposed at both ends of the continuous body 18. Therefore, in the second embodiment, one side of the thin film in the width direction (left and right direction in FIG. 5) is folded to form the folded pieces 14 and 15, and the width of the folded piece 14 is that of one side surface of the individual bowl 12. The width of the folded piece 15 is set to about 5 times the width of one side surface of the individual pot body 12 while being set to about 3 times the width. And in this continuous assembly pot 11, the folding pieces 14 and 15 are respectively arranged at both ends of the continuous body 18 and are bonded to the connecting pieces 13 to form the individual pot bodies 12, and are folded at both ends of the continuous body 18. The continuous body 18 is connected by sticking between the pieces 14 and 15 by the sticking part 20 which consists of a water-insoluble adhesive.

  As shown in FIG. 5, the continuous collecting bowl body 11 configured in this way is stored and provided in a pressed state, and when stretched in the stacking direction of the continuous body 18 in this state, as shown in FIG. 4. In addition, a large number of individual pot bodies 12 expand in a honeycomb shape, and the continuous collective pot bodies 11 having a predetermined size appear. When raising seedlings, the continuous collecting pot 11 is set in a raising seedling box in an expanded state, and each individual pot 12 is filled with cultivated soil and sown. Then, when the seedlings are nurtured for a predetermined number of days, the water-soluble adhesive on the folded surface of the connecting piece 13 and the folded pieces 14 and 15 and the water-soluble adhesive between the continuum 18 are degenerated by irrigation during the breeding. Therefore, when one end of the continuous body 18 constituting the continuous collecting pot body 11 is pulled at the time of transplanting after raising seedlings, as shown in FIG. 6, the continuous body 18 is drawn out in a row, thereby enabling efficient planting. It becomes possible. In this case, the length of the connecting portion 19 is approximately four times as long as the width of one side surface of the individual pot body 12, and can effectively cope with cultivation of crops that require a slightly wide inter-strain interval.

  Moreover, in this continuous assembly pot body 11, as FIG. 6 shows, in the state which tension | tensile_strength acted on the connection part 19 (connection piece) between the individual pot bodies 12 mutually connected at the time of transplantation, it is a sticking part. 17 and the bonding surface of the sticking part 20 are parallel to the pulling-out direction of the individual pot body 12, so that sufficient strength is ensured. Thereby, the sticking part 17 and the sticking part 20 do not peel at the time of transplantation, and the drawer | drawing-out of the individual pot body 12 is stabilized.

  Here, the material type of the thin film 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 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.

  In the first and second embodiments, the sewing machine is located at a position corresponding to the ridge of the hexagonal cylindrical body in the individual bowl bodies 2 and 12 formed by developing the continuous collection bowl bodies 1 and 11. It is desirable to form the eyes 22. 7-9 shows the perforation 22 formed in the connection piece 3 in 1st Embodiment. As shown in FIG. 7 and FIG. 8, four rows of perforations 22 are formed on the non-adhered portion (individual pot 2) formed between the adhering portions 7, 7 of each connecting piece 3 in the compressed state. The width of the perforation 22 is set to the width of one side surface of the individual pot body 2. As shown in FIG. 9, when the continuous assembly bowl body 1 in which the perforations 22 are formed is developed as described above, the hexagonal cylindrical individual bowl bodies 2 are evenly developed by the perforations 22, Sometimes the tension required is reduced and the labor of the operator is reduced. In addition, although the cutting width and interval of the perforation 22 can be appropriately selected, the seedlings are grown in the continuous collecting pot 1 (11), and as shown in FIGS. 3 and 6, the individual pots 2 (12) and 2 When the connecting portion 9 (19) is pulled out and transplanted to the field, it is necessary that these have strength that does not cut.

  Next, based on FIG. 10, the manufacturing method of the continuous assembly pot 1 of 1st Embodiment is demonstrated. First, a base paper 24 is drawn from each base paper roll 23 around which a wide thin film (base paper) is wound, and each base paper 24 is cut into a predetermined number of strip-like thin films 26 by a slitter 25. Each belt-like thin film 26 is sequentially guided to a cylinder-forming glue roller 27 and a cylinder-making apparatus 28 (molding rod), and a water-soluble adhesive is applied to one surface by the cylinder-making glue roller 27 and the cylinder-producing apparatus 28. Is formed into a cylindrical shape. Each strip-shaped thin film 26 formed into a cylindrical shape is sent to a pressure roller 29, and the inner surface is adhered to form strip-shaped connecting pieces 30a and 30b and strip-shaped folded pieces (not shown). Next, the strip-shaped connecting pieces 30a and 30b are arranged in a staggered manner in two upper and lower stages, and a non-water-soluble adhesive is applied in a streaky manner to the lower strip-shaped connecting piece 30b by the connecting piece gluing device 31. It is sent to the roller 32. Then, the belt-like connecting piece 30 a and the belt-like connecting piece 30 b are attached by the pressure roller 32, and the belt-like continuous body 33 is formed.

  At this time, belt-like folded pieces (not shown) having a predetermined width are arranged at both ends of the belt-like continuous body 33 and are stuck by the pressure roller 32. Thereby, the cross-sectional shape of the said strip | belt-shaped continuous body 33 becomes the same as the cross-sectional shape of the continuous body 8 (refer FIG. 2). Next, the belt-like continuous body 33 is sequentially guided to a laminating glue roller 34 and a laminating glue device 35, and a water-soluble adhesive is applied to the upper surface by the laminating glue roller 34, and by the laminating glue device 35. A water-insoluble adhesive is applied to the belt-like folded piece (one in which the folded piece 4 or the folded piece 5 is formed in a belt shape) located at the side end of the belt-like continuous body 33. Then, the belt-like continuous body 33 to which the adhesive is applied is cut into a predetermined width (corresponding to the height of the individual pot body 2) by the rotary cutter 36, and the continuous body 8 is formed. Then, the continuous body 8 is reversed 180 degrees every other sheet by the next reversing device 37 and sent to the laminating and sticking device 38. Here, the continuous assembly body 1 is completed by laminating and sticking the continuum 8 to each other via a water-soluble adhesive.

  Although not shown, a device for detecting the feed amount of the belt-like continuous body 33 is provided in the vicinity of the laminating glue roller 34, and when a predetermined amount of the belt-like continuous body 33 is fed to the rotary cutter 36. Then, the laminating glue roller 34 is raised, and the water-soluble adhesive is not applied to the upper surface of the belt-like continuous body 33 by an amount corresponding to the width of the single continuous body 8 (height of the individual bowl 2). ing. Thereby, a predetermined number of continuous bodies 8 are laminated and pasted by the laminating and sticking apparatus 38, and it becomes possible to take out one by one as the continuous collecting pot 1.

Apply adhesive. Then, only the portion glued by the tube making glue roller 27 by the tube making device 28 is folded and pasted by the pressure roller 29, whereby the respective strip-like connecting pieces 30a, 30b are formed. Next, the strip-shaped connecting pieces 30a and 30b are arranged in the same manner as in the first embodiment, and the non-water-soluble adhesive is applied in a streaky manner to the lower strip-shaped connecting piece 30b by the connecting piece gluing device 31. The piece 30a and the connecting piece 30b are attached by the pressing roller 32.

  Here, the opposing strip-shaped connecting pieces 30a and 30b are folded portions (portions corresponding to the folded portion 16 of the connecting piece 13) or the folded-back portions 16 are not attached to the strip-shaped connecting pieces 30a and 30b. The folding direction of the strip-shaped thin film 26 in the tube-making apparatus 28 is set so that the sides (part corresponding to the other side 21 of the connecting piece 13) are attached to each other. Further, strip-like folded pieces (the folded pieces 14 and the folded pieces 15 formed in a strip shape) having different cutting widths by the slitter 25 and folded-back widths by the cylinder making device 28 are processed in the same manner, and the strip-like folded pieces corresponding to the folded pieces 14 are processed. A piece is attached to one end of the belt-like continuous body 33, and a belt-like folded piece corresponding to the folded piece 15 is attached to the other end of the belt-like continuous body 33. Thereby, the strip | belt-shaped continuous body 33 which has the cross-sectional shape similar to the cross-sectional shape (refer FIG. 5) of the continuous body 18 is formed. Next, the belt-like continuous body 33 is sequentially sent to the laminating glue roller 34, the laminating glue device 35, and the rotary cutter 36, and the continuous body 18 is formed.

  Furthermore, the continuous body 18 is sent to the reversing device 37 and the laminating and sticking device 38 to complete the continuous assembly bowl body 11 in which the hexagonal tubular individual bowl bodies 12 are assembled. In addition, the point which detects the feed amount of the strip | belt-shaped continuous body 33, and provides the area | region which does not apply | coat a water-soluble adhesive on the upper surface of the said strip | belt-shaped continuous body 33 is the same as the above.
