[0020] An embodiment is described with reference to the accompanying drawings. The present embodiment relates to a bulb or seedling belt, a method for manufacturing the same, and an apparatus for manufacturing the same. The bulb or seedling belt is a belt-shaped object in which bulbs or seedlings are arranged at prescribed intervals. In the bulb or seedling belt, the bulbs or seedlings are arranged so that their tops and bottoms are aligned with respect to the width direction of the belt. An elongated groove of a prescribed width is dug in a nursery, and the bulb or seedling belt is arranged in the groove along the long side direction and covered with soil, whereby the bulbs or seedlings are planted at a prescribed depth at prescribed intervals at one time. According to the bulb or seedling belt, bulbs or seedlings can be planted at prescribed intervals and at prescribed depths more efficiently than planting bulbs or seedlings one by one.

[0021] [Bulb or seedling belt]

[0022] Figure 1A is a schematic top view of a bulb or seedling strip 10, Figure 1B Schematic cross-sectional views of the bulb or seedling tape 10. As shown in these figures, the bulb or seedling tape 10 has a structure in which bulbs or seedlings 18 are arranged in a predetermined direction between a first tape 12 and a second tape 14 bonded together by an adhesive 16.

[0023] The bulb or seedling 18 may be any of the bulbs, seeds, and seedlings of crops. The bulb may include bulbs, corms, tubers, rhizomes, pseudobulbs, and side branches. In particular, in the bulb or seedling belt 10 of the present embodiment, the bulbs or seedlings 18 are arranged with the bud side 18a facing one side in the width direction of the bulb or seedling belt 10, and the root side 18b facing the opposite side in the width direction of the bulb or seedling belt 10. Therefore, as the bulb or seedling 18, bulbs or seedlings that have directionality when planted are particularly suitable for the present embodiment. Specifically, as the bulb or seedling 18, for example, it may be bulbs of garlic, etc., seed potatoes of potatoes, etc., or seeds of edamame, broad beans, lentils, peanuts, corn, pumpkin, sunflower, etc. Figure 1A and Figure 1B In the figure, as a bulb or seedling 18, a garlic bulb is shown.

[0024] The first belt 12 and the second belt 14 can be belts made of nonwoven fabric, woven fabric, or paper. The first belt 12 and the second belt 14 are preferably made of materials that are easily decomposed in soil. In the present embodiment, the first belt 12 and the second belt 14 are not limited thereto, and in particular, may be nonwoven fabrics, for example, nonwoven fabrics with a mesh size of 0.1 mm to 2 mm.

[0025] The adhesive 16 for bonding the first tape 12 and the second tape 14 together can be, for example, an adhesive containing starch. In the present embodiment, an adhesive obtained by spraying water on a thin film of rice paper (oblaat) made of starch or the like is used as the adhesive 16. Alternatively, the adhesive 16 can be, for example, an adhesive containing polyvinyl alcohol (PVA). In this case, an adhesive obtained by spraying water on a tape formed of PVA in a thin film tape is used.

[0026] [Method for manufacturing bulb or seedling tape]

[0027] Figure 2 It is a flowchart showing the outline of the method for manufacturing the bulb or seedling tape 10 according to the present embodiment. Figure 3A and Figure 3B It is a schematic diagram which schematically shows the state of each stage when manufacturing the bulb or seedling tape 10.

[0028] First, in step S1, a first tape 12, for example, made of nonwoven fabric, arranged on the lower side is prepared on a table 31. Then, in step S2, a rice paper tape 22 is overlapped on the first tape 12. Next, in step S3, water 24 is sprayed on the rice paper tape 22. In step S4, the sprayed water 24 is waited to penetrate into the rice paper tape 22. The rice paper soaked with water becomes a paste, and becomes a paste-like rice paper tape 26. In step S5, bulbs or seedlings 18 are placed on the paste-like rice paper tape 26 at a predetermined interval. Next, in step S6, the second tape 14 is overlapped in a manner matching the first tape 12 so as to cover the paste-like rice paper tape 26 and the bulbs or seedlings 18. Thereafter, in step S7, the first tape 12 and the second tape 14 are pressed together. This pressing is performed, for example, by pressing the entire second tape 14 side with a sponge roller 32. Finally, in step S8, the paste-like rice paper tape 26 is dried, thereby bonding the first tape 12 and the second tape 14 with the bulb or seedling 18 sandwiched therebetween. The dried rice paper tape 26 remains as an adhesive 16 between the first tape 12 and the second tape 14. As described above, the bulb or seedling tape 10 is completed.

[0029] In addition, depending on the situation, the spraying of the water 24 may be performed after the placement of the bulbs or seedlings 18 instead of before the placement of the bulbs or seedlings 18. In addition, depending on the situation, the bulbs or seedlings 18 may be placed on the first belt 12, and the rice paper belt 26 may be overlapped thereon. That is, the rice paper belt 26 and the bulbs or seedlings 18 may be placed on the upper surface side of the first belt 12, and the order of the rice paper belt 26 and the bulbs or seedlings 18 may be arbitrary. In any case, the spraying of the water 24 is performed after the placement of the rice paper belt 26.

[0030] [Device for manufacturing bulb or seedling tape]

[0031] A manufacturing apparatus 100 for manufacturing the bulb or seedling tape 10 by the above-mentioned manufacturing method will be described. Figure 4 1 is a diagram schematically showing the outline of the manufacturing apparatus 100. In the figure, the belt is usually conveyed from right to left, and the bulb or seedling belt 10 is completed at the left end of the manufacturing apparatus 100.

[0032] The manufacturing device 100 includes a conveying section 110 of a conveyor belt. The manufacturing device 100 generally includes a first belt supply section 120, a rice paper belt supply section 130, a spray unit 140, a bulb or seedling supply section 150, a second belt supply section 160, and a crimping section 170 from the upstream side toward the downstream side. In addition, the manufacturing device 100 includes a control device 180. The first belt supply section 120 supplies the first belt 12. The rice paper belt supply section 130 supplies the rice paper belt 22. The spray unit 140 sprays water 24 on the rice paper belt 22. In the bulb or seedling supply section 150, bulbs or seedlings 18 are supplied onto the belt being conveyed. The second belt supply section 160 supplies the second belt 14. The crimping section 170 crimps the first belt 12 and the second belt 14. The control device 180 has a computer and controls the operation of each part of the manufacturing device 100.

[0033] In the manufacturing device 100 of the present embodiment, the conveying section 110 has a belt conveyor 111 for conveying provided in the bulb or seedling supply section 150, the second belt supply section 160 and the crimping section 170. The belt conveyor 111 is a common conveyor, and a conveyor belt 113 is supported in a wound manner between a set of rollers 112. The belt conveyor 111 is configured so that the conveyor belt 113 rotates in the longitudinal direction by rotating one of the rollers 112 through a motor 114. The first belt 12 of the bulb or seedling belt in the process of manufacturing is configured to be placed on the horizontally extending conveyor belt 113, and the belt is conveyed in the longitudinal direction through the conveyor belt 113.

[0034] The first tape supply unit 120 is provided with a first tape roll 12a around which the first tape 12 is wound. The first tape 12 is drawn from the first tape roll 12a and supplied to the manufacturing device 100. The first tape supply unit 120 is provided with a plurality of rollers so as to convey the first tape 12 in an appropriate direction while imparting appropriate tension to the first tape 12. The first tape 12 drawn from the first tape roll 12a is conveyed onto the conveyor belt 113 of the conveyor unit 110 via the stage 121.

[0035] The rice paper tape supply unit 130 is provided with a rice paper tape roll 22a on which the rice paper tape 22 is wound. The rice paper tape 22 is drawn out from the rice paper tape roll 22a and supplied to the manufacturing device 100. The rice paper tape supply unit 130 is provided with a plurality of rollers in such a manner that the rice paper tape 22 is conveyed in an appropriate direction while imparting appropriate tension to the rice paper tape 22. The first roller 131 is provided in such a manner that the first belt 12 is clamped between the first roller 131 and the table 121. The rice paper tape 22 drawn out from the rice paper tape roll 22a is hung on the first roller 131, passes through the first roller 131, and overlaps on the first belt 12. The rice paper tape 22 is conveyed downstream from the first roller 131 in a state where the rice paper tape 22 is overlapped on the first belt 12.

[0036] A spray nozzle 141 of a spray unit 140 is provided downstream of the first roller 131. The spray nozzle 141 is configured to spray water 24 toward the rice paper strip 22 on the first belt 12. The amount of water 24 sprayed from the spray nozzle 141 is adjusted to an amount suitable for making the rice paper strip 22 into a paste.

[0037] The first belt 12 carrying the rice paper belt 26 that has been sprayed with water 24 and turned into a paste is placed on the conveyor belt 113 of the conveying unit 110 and further transported in the longitudinal direction. In the bulb or seedling supply unit 150, a space is provided around the conveyor belt 113 so that the operator can place the bulb or seedling 18 on the first belt 12 and the paste-like rice paper belt 26 being transported. Marks may be provided at regular intervals on the conveyor belt 113 so that the operator can identify the intervals at which the bulbs or seedlings 18 are placed. In addition, the placement of the bulb or seedling 18 may be performed by a machine instead of by the operator.

[0038] A second belt supply unit 160 is provided downstream of the bulb or seedling supply unit 150. The second belt supply unit 160 is provided with a second belt roller 14a on which the second belt 14 is wound. The second belt 14 is drawn out from the second belt roller 14a and supplied to the manufacturing device 100. In the second belt supply unit 160, a plurality of rollers are provided in a manner that the second belt 14 is conveyed in an appropriate direction while imparting appropriate tension to the second belt 14. The second roller 161 is provided in a manner that guides the second belt 14 onto the first belt 12 or the like on which the bulb or seedling 18 is carried on the conveyor belt 113. The second belt 14 drawn out from the second belt roller 14a is hung on the second roller 161, and is overlapped on the first belt 12 or the like on which the bulb or seedling 18 is carried through the second roller 161.

[0039] A sponge roller 171 is provided at the crimping section 170 downstream of the second belt supply section 160. The sponge roller 171 presses the belt that is moved on the conveyor belt 113 and is composed of the first belt 12, the paste-like rice paper belt 26, the bulb or seedling 18, and the second belt 14, so that they are crimped. When the paste-like rice paper belt 26 dries after passing through the sponge roller 171, the bulb or seedling belt 10 is completed. At the terminal of the conveyor belt 113, the completed bulb or seedling belt 10 is rolled up or stacked in a box, and the bulb or seedling belt 10 is shipped.

[0040] [Regarding the manufacture of bulbs or seedling tapes]

[0041] In the manufacture of the bulb or seedling band 10 of the above-mentioned present embodiment, a film-like rice paper band 22 is used in the bonding of the first band 12 and the second band 14. The rice paper band 22 is easier to handle than, for example, a liquid paste such as starch. That is, in the case where a liquid paste is applied or sprayed onto the first band 12, it is troublesome to clean the equipment because the paste solidifies when the manufacturing device is not in operation. In contrast, the rice paper band 22 used in the present embodiment itself is a film-like material, so it is easy to handle. In addition, pure water 24 is also sprayed to make the rice paper band 22 into a paste-like rice paper band 26, so the management of the equipment is not so troublesome.

[0042] Furthermore, by using the rice paper tape 22, it is easier to evenly apply the paste to the first tape 12 than by using a liquid paste. Furthermore, if the uniform paste-like rice paper tape 26 attached to the first tape 12 and the second tape 14 is dried, a cured adhesive 16 having a moderate viscosity is obtained. Even if a relatively thin nonwoven fabric or the like is used for the first tape 12 and the second tape 14, the adhesive 16 can be used to impart a moderate rigidity to the completed bulb or seedling tape 10. Since the bulb or seedling tape 10 has a moderate rigidity, it is easy to arrange the bud side 18a side of the bulb or seedling 18 on the upper side and the root side 18b side on the lower side when the bulb or seedling tape 10 is used, that is, when planting.

[0043] In addition, when nonwoven fabrics are used for the first belt 12 and the second belt 14, there is a concern that if a liquid paste is used, the paste may seep out from the gaps in the mesh nonwoven fabric to the back side, contaminating the manufacturing equipment or causing the finished bulbs or seedlings to stick to each other. In order to prevent such a situation, the quality and quantity of the paste need to be strictly managed so that the liquid paste does not seep out to the back side. In contrast, in the present embodiment using the rice paper belt 22, the paste-like rice paper belt 26 can be easily prevented from seeping out to the back side by suppressing the amount of the sprayed water 24. Such an effect can be significantly achieved, especially when the first belt 12 and the second belt 14 use nonwoven fabrics with a mesh size of about 0.1 mm to 2 mm.

[0044] In addition, by using water 24 in a manner that does not cause the sticky rice paper tape 26 to ooze out to the back side, rapid drying can also be achieved. The rapidity of drying is related to the improvement of the manufacturing efficiency of the bulb or seedling tape 10.

[0045] [First Modification]

[0046] In the embodiment of manufacturing the above-mentioned bulb or seedling belt 10, the case of using rice paper belt 22 as an adhesive for bonding the first belt 12 and the second belt 14 is exemplified. It is also possible to use a belt-shaped polyvinyl alcohol (PVA) instead of the rice paper belt 22. As in the above-mentioned embodiment, by spraying water on the PVA belt, the PVA is pasted and acts as an adhesive for bonding the first belt 12 and the second belt 14. In this way, in the manufacture of the bulb or seedling belt 10, various paste-forming belts that are pasted by wetting can be used in the same way as the rice paper belt 22 and the PVA belt. In this way, it is not limited to using rice paper belts made of starch, and even if other raw materials such as PVA are used, the same function can be exerted and the same effect can be obtained.

[0047] [Second Modification]

[0048] In the embodiment of manufacturing the bulb or seedling tape 10 described above, one nonwoven tape is used for each of the first tape 12 and the second tape 14. In contrast, in this modification, the tapes corresponding to the first tape 12 and the second tape 14 are each formed by overlapping two tapes of nonwoven fabric or the like, a portion of which is formed.

[0049] FIG. 5A to FIG. 5D The structure of the bulb or seedling belt 11 of this modification is schematically shown. The same reference numerals are given to the same parts as those of the above-mentioned embodiment, and the description thereof is omitted. Figure 5A It is a schematic top view of the bulb or seedling belt 11 of this modification. Figure 5B , Figure 5C and Figure 5D The bulb or seedling belt 11 of this modification is respectively Figure 5A Schematic cross-sectional views along lines BB, CC and DD are shown.

[0050] As shown in these figures, the lower belt 13 corresponding to the first belt 12 of the above-mentioned embodiment is formed by overlapping a portion of the third belt 13a and the fourth belt 13b, which are narrower in width than the first belt 12 of the above-mentioned embodiment, near the center in the width direction. Similarly, the upper belt 15 corresponding to the second belt 14 of the above-mentioned embodiment is formed by overlapping a portion of the fifth belt 15a and the sixth belt 15b, which are narrower in width than the second belt 14 of the above-mentioned embodiment, near the center in the width direction. For example, the third belt 13a and the fourth belt 13b have a width of about 50 mm, and they overlap to form the lower belt 13 with a width of about 80 mm, but it is not limited to this. The same is true for the upper belt 15.

[0051] The manufacturing method of the bulb or seedling belt 11 of this modification is also basically the same as the manufacturing method of the bulb or seedling belt 10 of the above-mentioned embodiment. In step S1, instead of disposing one piece of the first belt 12, the third belt 13a and the fourth belt 13b are disposed in a manner that their parts overlap each other. Therefore, the first belt supply unit 120 is configured to supply the third belt 13a and the fourth belt 13b as belts equivalent to the first belt 12 of the above-mentioned embodiment while drawing them out, and to make them overlap each other partially.

[0052] In step S2, rice paper tape 22 is stacked on these tapes. In step S3, water 24 is sprayed on rice paper tape 22. In step S4, the sprayed water 24 is waited to penetrate into rice paper tape 22. The rice paper soaked with water becomes paste, and becomes paste-like rice paper tape 26. In step S5, bulbs or seedlings 18 are placed on paste-like rice paper tape 26 at predetermined intervals.

[0053] In step S6, instead of overlapping one sheet of the second tape 14 so as to cover the paste-like rice paper tape 26 and the bulb or seedling 18, the fifth tape 15a and the sixth tape 15b are arranged so as to overlap each other partially. Therefore, the second tape supply unit 160 is configured so as to supply the fifth tape 15a and the sixth tape 15b as tapes equivalent to the second tape 14 of the above-mentioned embodiment while drawing them out, and so as to overlap each other partially.

[0054] In step S7, the third tape 13a, the fourth tape 13b, the fifth tape 15a, and the sixth tape 15b are crimped, for example, by a sponge roller 32. The paste of the rice paper tape 26 also penetrates into the overlapping portion of the third tape 13a and the fourth tape 13b, so that the third tape 13a and the fourth tape 13b are bonded together. Similarly, the paste of the rice paper tape 26 also penetrates into the overlapping portion of the fifth tape 15a and the sixth tape 15b, so that the fifth tape 15a and the sixth tape 15b are bonded together. In step S8, by drying the paste-like rice paper tape 26, the third tape 13a, the fourth tape 13b, the fifth tape 15a, and the sixth tape 15b are bonded together with the bulb or seedling 18 sandwiched therebetween, thereby completing the bulb or seedling tape 11. Thus, although two tapes are used for the lower tape 13 and the upper tape 15 respectively, the method for manufacturing the bulb or seedling tape 11 is the same as the above-mentioned embodiment except that the tapes need to be positioned, and there is no increase in the number of steps.

[0055] Although two bands are required to form the lower band 13 and the upper band 15 respectively, by using relatively cheap and narrow third band 13a, fourth band 13b, fifth band 15a and sixth band 15b, the bulb or seedling band 11 as a whole can be manufactured relatively cheaply compared to the above-mentioned embodiment using the wide first band 12 and second band 14.

[0056] In this modification, of course, other paste-forming tapes such as PVA tapes may be used in place of the rice paper tape as in the first modification.

[0057] As mentioned above, although the present invention was described by showing the preferred embodiment, it is needless to say that the present invention is not limited to the above-mentioned embodiment, and various modifications can be made within the scope of the present invention.
