Description

Technical Field

[0001] The present invention relates to an auxiliary tool for putting waste materials into a plastic bag. Specifically, it relates to a technology that enables the input of waste materials with irregularities or the like without being caught by folding an input auxiliary member into a rod shape, inserting it into the plastic bag, and expanding it into a substantially circular shape.

Background Art

[0002] When processing rubble from civil engineering work sites and building demolition sites, and branches from tree pruning, etc., workers need to store these in plastic bags. At these sites, the size and shape of rubble, etc., vary widely, the work platforms are poor, and the site cleaning work becomes extremely difficult.

[0003] Moreover, especially in the case of disaster areas, etc., reconstruction is an urgent task, and it can be said that prompt response is required. However, the work of packing rubble with poor work platforms takes a lot of time and effort. Therefore, it can be said that a more efficient packing method is required.

[0004] One of the factors that cause the work to take time is that when putting rubble into a plastic bag, the plastic bag does not stand firm and the opening is opened by the hand of another worker. That is, for one plastic bag, the work is carried out by two people, and there is a current situation where the efficiency is not good. Therefore, a technology that allows waste materials, etc., to be easily put into a plastic bag by one person would be suitable.

[0005] Therefore, various technical proposals have been made in view of such a current situation. For example, a technology with the invention name of "Sandbag manufacturing machine" is disclosed (see Patent Document 1). Specifically, "Providing a sandbag manufacturing machine that can easily perform the work of bagging earth and sand by one person without lifting the sandbag, and can efficiently bag earth and sand containing moisture." is set as the problem, and the solution means is "Attach a roller conveyor 12 along the front-rear direction to the base 11, and stand a plurality of columns 13 annularly on the base 11 except for the front side, and on the upper part of the column 13, provide an upper frame 15 having a substantially C-shaped plane with an open front, insert the sandbag 2 into the bag insertion part 14 formed inside each of the annularly arranged columns 13, fold back the mouth part 3 of the sandbag 2 and support it on the upper frame 15 having a substantially C-shaped plane, and then put earth and sand 5 into the sandbag 2 from the mouth part 3, and pull out the filled sandbag 7 to the front side by the roller conveyor 12." Such technology is disclosed and is a known technology. The technology described in Patent Document 1 has a common problem with the present invention in that the work of bagging earth and sand can be easily performed by one person without lifting the sandbag. However, the technology described in Patent Document 1 has a drawback that it requires the labor and time for such a setting because the earth and sand 5 are put into the sandbag 2 from the mouth part 3 after the mouth part 3 of the sandbag 2 is folded back and supported on the upper frame 15 having a substantially C-shaped plane.

[0006] In addition, a technology with the invention name of "Sandbag and sandbag installation method and embankment construction method using the same" is disclosed (see Patent Document 2). "Specifically, "Providing an auxiliary tool for manufacturing sandbags for efficiently manufacturing sandbags." is set as the problem, and as the solution means, "The sandbag manufacturing auxiliary tool 1 includes a lid body 2 having an earth and sand inlet for putting in earth and sand, and a stand body on which the lid body is placed. The stand body includes a holding part for holding the lid body, a plurality of legs for supporting the holding part, a reinforcing part 33 installed between the plurality of legs, and a bag hanging part 34 fixed to the reinforcing part. The bag hanging part has a length capable of hanging a plurality of sandbags 4 in addition to the length of the earth and sand inlet." Such technology is disclosed and is a known technology. However, the technology described in Patent Document 1 requires a large-sized housing and has not achieved the problem of the present invention of being able to be compactly stored.

[0007] In addition, a technology with the invention name "collecting tool" is disclosed (see Patent Document 3). Specifically, "it is an object to provide a collecting tool capable of increasing variations of bags that can be used for collecting waste, and as a solution means, 'the collecting tool 1 is arranged so as to surround the opening end of the bag 100 that houses the waste D1 inside, and the folding part 100a of the opening end of the bag 100 is hooked in a state where the opening end of the bag 100 is folded back to the outside. A frame body 11, three wires 13, and clips 12 provided at one end in the longitudinal direction of each of the three wires 13 for clamping the frame body 11 and the opening end of the bag 100 together in a state where the folding part 100a of the bag 100 is hooked to the frame body 11, and a fixing part 14 for collectively supporting the other ends of the three wires 13 and fixing them to the construction material' is disclosed and is a known technology. However, the collecting tool 1 described in Patent Document 3 is used, for example, at a construction site of a building, by sucking the fixing part 14 onto members such as metal beams and iron plates provided on construction materials such as the ceiling and walls of the building under construction, so that the frame body 11 and the bag 100 are suspended from the construction material. Therefore, it cannot be used outdoors without walls or ceilings, and it is different from the present invention without such restrictions in terms of its effects.

Modes for Carrying Out the Invention

[0020] The present invention is an auxiliary tool for facilitating the insertion of waste material H into a plastic bag G, which is composed of a foldable insertion auxiliary member 10. The insertion auxiliary member 10 is formed by arranging a sheet-like member 20 and a plurality of plate-like members 30 in parallel at a predetermined interval. The space between each of the plate-like members 30 forms a bending portion 40, or the insertion auxiliary member 10 is provided with bending grooves 41 on a single elastic material 11, and each of the bending grooves 41 is used as the bending portion 40. With the bending portion 40, the insertion auxiliary member 10 is folded into a rod shape and inserted into the plastic bag G and expanded into a substantially circular shape, which is the most prominent feature. Hereinafter, it will be described with reference to the drawings. However, it is not limited to the shapes and configurations described in such drawings, and can be changed within the scope where the effects obtained by the creation of the technical idea of the present invention can be exerted.

[0021] FIG. 1 is a basic configuration explanatory diagram for explaining the basic configuration of the waste material insertion auxiliary tool for a plastic bag according to the present invention. FIG. 1(a) shows the state where the insertion auxiliary member 10 is folded, FIG. 1(b) shows the state where the insertion auxiliary member 10 is expanded, FIG. 1(c) shows the case where the insertion auxiliary member 10 is composed of a sheet-like member 20 and a plurality of auxiliary members 30 and shows the folded state, FIG. 1(d) shows the side view of the expanded state in the case where the insertion auxiliary member 10 is composed of a sheet-like member 20 and a plurality of auxiliary members 30, FIG. 1(e) shows the folded state in the case where the insertion auxiliary member 10 is composed of a sheet-like member 20 and a plurality of auxiliary members 30, and FIG. 1(f) shows the side view of the expanded state in the case where the insertion auxiliary member 10 is configured with bending grooves 41 provided on both sides of a single sheet-like member 20.

[0022] The waste material insertion auxiliary tool 1 for a plastic bag is an auxiliary tool for facilitating the insertion of waste material H into a plastic bag G, which is composed of a foldable insertion auxiliary member 10. The insertion auxiliary member 10 is formed by arranging a sheet-like member 20 and a plurality of plate-like members 30 in parallel at a predetermined interval. The space between each of the plate-like members 30 forms a bending portion 40, and with the bending portion 40, the insertion auxiliary member 10 is folded into a rod shape and inserted into the plastic bag G and expanded into a substantially circular shape.

[0023] The input assisting member 10 is formed by arranging a sheet-like member 20 and a plurality of plate-like members 30 side by side at a predetermined interval, and can be folded into a rod shape by a bent portion 40 between the plate-like members 30, or is formed by providing a folding groove 41 in a single elastic material 11. It can be folded into a rod shape by the bent portion 40. Further, since there are almost no irregularities on the inner surface side of the unfolded input assisting member 10, it exhibits an excellent effect that waste materials having a protruding shape, pruned tree branches, etc. are not caught on the side surface of the plastic bag and can be inserted without breaking through.

[0024] The elastic material 11 is a material composed of a single sheet, specifically, for example, materials such as urethane foam and silicon, and has a high elastic limit and is difficult to plastically deform. Note that the elastic material 11 is not limited to these materials and can be changed within a material having physical properties that exhibit its effects. That is, it is necessary that the input assisting member 10 has a strength that does not break even when it is folded by forming the bent portion 40.

[0025] The sheet-like member 20 is a sheet that serves as a base for arranging the plate-like members 30.

[0026] The plate-like member 30 is made of a material such as a strip-shaped relatively hard resin arranged on the sheet-like member 20, and the plate-like members 30 are continuously arranged so as to form an annular shape, forming a single ring-shaped formation. Regarding specific dimensions, since the size of the commonly used plastic bag G is often 480 (width) X × 600 (height) Y, taking this case as an example, first, the length L of the opening edge portion is 480 (width) X × 2 = 960 mm. When the number of plate-like members 30 is 11, the width X is set to a size obtained by equally dividing 85% to 95% of the length L of the opening edge portion of the plastic bag G into 11 equal parts, and the height Y direction is formed to be about 100 mm to 200 mm larger than 600 mm.

[0027] The bent portion 40 is a portion that is bent in the input assisting member 10 so as to have an overall annular shape, and is a portion where a weak portion is provided between the plate-like members 30 or by the bending groove 41 to facilitate bending. Such a bent portion 40 needs to have creep resistance that can withstand repeated bending.

[0028] The bending groove 41 is a groove formed to constitute a weak portion against bending so as to form the bent portion 40 when the input assisting member 10 is composed of a single elastic member 11.

[0029] The debris bag G is a bag used for putting out debris and garbage at the site, is larger than a normal flowerpot, and is used for transporting and storing debris such as debris, garbage, firewood, and debris, and has a certain thickness and is strong and not easily torn. Since many of these debris are pointed, it is preferable to use polypropylene (PP) that is not easily torn as the material.

[0030] The binding band 50 is a member that holds the folded state of the input assisting member 10 according to the present invention as shown in FIGS. 1(a) and 2(a) with a Velcro (registered trademark) fastener or a cord body, etc., and releases it when unfolding the folded input assisting member 10.

[0031] The waste material H refers to industrial waste that is discarded as unnecessary when old houses and buildings are demolished. The waste material includes concrete blocks, brick pieces, asphalt pieces, wood, waste plastics, metal scraps, glass scraps, etc. These large amounts of waste material H generated from the demolition of buildings were mostly treated as garbage in the past, but in order to promote the effective use of limited resources and the proper treatment of industrial waste, in accordance with the provisions of the Construction Recycling Law fully implemented in 2002, the waste material H is sorted by item and utilized as recycled resources in various forms.

[0032] The opening edge length L is the circumferential length of the frontage of the plastic bag G. Generally, the size of plastic bags commonly used is often 480 (width) X × 600 (height) Y. Taking this case as an example, the opening edge length L is 480 (width) X × 2 = 960 mm. However, this is just an example, and there are other standard sizes, and plastic bags G of those standard sizes are not excluded.

[0033] FIG. 2 is an explanatory diagram of an embodiment for explaining the bent portion of the waste material input assisting tool for a plastic bag according to the present invention. FIG. 2(a) is an enlarged view of a part of a side surface when a plurality of plate-like members 30 are arranged in parallel at a predetermined interval on the sheet-like member 20 of the input assisting member 10. FIG. 2(b) shows a case where the input assisting member 10 has a plurality of plate-like members 30 arranged in parallel at a predetermined interval on the sheet-like member 20, and an outer frame is configured to surround it in a substantially U-shape by the plate-like members 30 with three pieces, and the other pieces are continuously folded alternately so as to overlap. FIG. 2(c) is an enlarged view of a side surface of a state where the input assisting member 10 has a bent portion 40 provided on a single elastic material 11. FIG. 2(d) shows a state where the input assisting member 10 has a bent portion provided on a single elastic material 11, and a bending groove 41 serving as the bent portion 40 becomes a vulnerable part, showing a folded state. Also, bending grooves 41 for facilitating folding so that three pieces become a substantially U-shaped outer frame and bending grooves 41 for folding inside the outer frame are provided at predetermined positions on both surfaces of the elastic material 11, respectively, showing a folded state. Note that whether it is a mountain fold or a valley fold is determined by the bending groove 41 formed on one side or the opposite side of a single elastic material 11. Also, when a configuration in which a plurality of plate-like members 30 are arranged in parallel at a predetermined interval on the sheet-like member 20 of the input assisting member 10 is used, the three bent portions 40 are mountain folds, and the folded pieces to be installed are valley folds. By bending by the bent portions 40, it is possible to configure a folded state as shown in FIGS. 2(b) and 2(d).

[0034] FIG. 3 is an explanatory diagram for explaining another embodiment of the bent portion of the waste material input assisting tool for a plastic bag according to the present invention. FIG. 3(a) shows a state where the input assisting member 10 in a folded state is inserted into the plastic bag G. FIG. 3(b) shows a state where the input assisting member 10 in a folded state is deployed to guide and insert the waste material H into the plastic bag G. FIG. 3(c) shows a state where the input assisting member 10 is pulled out after the waste material H is input into the plastic bag G. FIG. 3(d) shows a state of the plastic bag G where the opening of the plastic bag G is closed with a tying string after a predetermined amount of waste material is input.

[0035] As shown in FIG. 3(a), the opening of the plastic bag G is widened and the input assisting member 10 is folded. In this case, since the cross-sectional area is smaller than that of the opening, the input assisting member 10 can be easily inserted. At this time, it is tied with the binding band 50. After the input assisting member 10 is inserted into the plastic bag G and the binding band 50 is released and deployed, as shown in FIG. 3(b), the plastic bag opens wide and the input assisting member 10 serves as a guide, enabling the waste material H to be smoothly input into the plastic bag G. Then, as shown in FIG. 3(c), when the waste material H is filled and reaches the allowable capacity, the input assisting member 10 is pulled out, and as shown in FIG. 3(d), it is tied with a closing string by the tying string at the opening and discarded. According to the waste material input assisting tool for a plastic bag according to the present invention when the input assisting member is inserted into and removed from the plastic bag in the above series of operations, since the one-side end portions of each plate etc. are rounded, smooth insertion and removal without being caught by the plastic bag are possible.

[0036] FIG. 4 is an explanatory diagram for explaining the details of the waste material input assisting tool for a plastic bag according to the present invention. FIGS. 4(a) and 4(b) show a case where the input assisting member 10 is composed of a sheet-like member 20 and a plurality of plate-like members 30, and illustrate a case where a rounded portion R process is performed on the tip of the plate-like member 30 deployed in a ring shape. Such a rounded portion R includes two types, namely, a rounded portion RA (FIG. 4(a)) with respect to the circumferential direction as shown in FIG. 4(a), and a rounded portion RB (FIG. 4(b)) at the corner where the inner wall of the plastic bag G contacts the tip of the input assisting member 10 as shown in FIG. 4(b). FIG. 4(c) is shown for explaining the length L of the opening edge portion of the plastic bag G.

Industrial Applicability

[0037] According to the waste material input assisting tool for plastic bags according to the present invention, when throwing waste materials such as rubble generated at a construction site or a disaster area into plastic bags, the work that was previously carried out by two people can now be done by one person, making the work easier. Waste materials and the like can be efficiently collected, and it is considered to have high industrial applicability because it helps to reduce the labor burden at a civil engineering work site.
