Description

The present invention relates to a packing device used for packing building materials, housing equipment, and the like.

Currently, packaging of building materials and the like is mainly performed using cardboard, and this cardboard is basically disposable, which is not preferable from the viewpoint of effective use of resources. On the other hand, plastic packaging materials that can be loosened have recently been provided. Although this packaging material is collected, it is left naked in the construction site until collection.

These packing materials are in direct contact with the external environment. For this reason, the packaging specification is somewhat heavy. For example, the plastic plate is too thick, the plate area is too large, the company name and the product number need to be printed individually, and parts that protect the corners are required separately. In addition, since it is left untreated at the construction site until it is unpacked and collected, there are problems such as dirt and scratches, and some parts are lost.

Problems to be solved by the invention

In this invention, by using a returnable box type packing device, the entire packing device of one tsubo unit (hereinafter referred to as a unit packing device) is further covered from the outside, and the plate-shaped packaged items are doubled. Protect from the outside and protect from scratches and dirt. With this configuration, the unit packaging device can be a simple packaging. In addition, the height of the returnable packaging device can be adjusted, and the purpose is to change the height in accordance with the number of unit packing devices that are different for each construction site. Furthermore, it aims at folding and accommodating a unit packing apparatus in the inside until collection | recovery of a packing apparatus.

Means to solve the problem

In the first aspect of the present invention, the plastic upper canopy type packing device that can be divided into several parts in the height direction and can be adjusted in height and laid at the bottom of a plurality of unit packing bodies (hereinafter referred to as packing groups) are used. A packing device comprising: a packing device stability auxiliary member and a pallet, wherein the packing group is packed in a sandwich manner by a canopy type packing device at the top and a packing device stability auxiliary member at the bottom and a pallet. provide.

According to the invention of the above-mentioned claim, the upper canopy type packing apparatus is divided into a plurality of parts in the height direction, the one that contacts the top of the packing group is the first stage, and the one that is one size larger on the outside is two stages. In the following, the larger items cover and pack the packing group while sliding on the outside. In this way, the height can be adjusted while sliding from the top according to the quantity of the packing group, so there is no empty space and the truck space for delivery can be used effectively. In addition, since the plate-shaped items to be packed are double-packed, the unit packing device located inside can be made relatively simple if the returnable box type packing device located outside is made sturdy. It can be protected until the collection time.

According to the first aspect of the present invention, if the upper canopy type packing device divided into a plurality of parts is used in the opposite way to that of 0006, that is, it is installed from the bottom one and is slightly smaller on it. As you pile up, it looks like a jumping box. In this case, a gap is formed between the packing group and the upper canopy packing device. This is because the returnable box type packing device receives the upper load when stocking in a warehouse or the like. In the sliding type of item 0006, the upper load is received by an internal packaged object as in the current cardboard packaging.

According to the second aspect of the present invention, the unit packing device can be folded in its entirety when not in use, and can be stored in a compact state in the returnable box type packing device. Since it is stored in such a state, scratches, dirt and loss can be prevented, and it can be loosened.

The invention's effect

According to the present invention, in order to double-pack the plate-shaped packaged object, the outer packing device is made firmly, and if the company name, product number, handling, etc. are collectively printed, the internal unit packing device Can be made relatively simple, reducing costs. The internal packing device can be identified by coloring. Further, the unit packing device is safely protected inside the outer packing device until it is collected. Furthermore, the height can be adjusted in accordance with the quantity of unit packing devices that differ from building site to building site, so that there is no waste in warehouses and truck space.

1 is a simplified perspective view of a three-part example of the invention of claim 1, FIG. 2 is a plan view, a long-side cross-sectional view, and a short-side cross-sectional view, and FIG. FIG. 4 is an explanatory diagram showing the positional relationship of the first, second, and third stages of the three-divided upper canopy packing device, FIG. 4 is an explanatory diagram of a slide type height adjustment method, and FIG. 5 is an explanatory diagram of a stacked type height adjustment method. The returnable box type packing apparatus 1 includes an upper canopy type packing apparatus 2, a packing apparatus stability auxiliary member 3, and a pallet 4. The packing group 5 is composed of 36 unit packing bodies 6. FIG. 8 is a perspective view of the packing group 5. The upper canopy packing device 2 and the packing device stability auxiliary member 3 are molded products such as plastic and plastic elastomer. Alternatively, it can be made of lightweight steel.

FIG. 2 is an example of three divisions of the upper canopy packing device 2 and includes a first stage 7, a second stage 8, and a third stage 9. The packing group 5 takes 3 rows and 12 stages as an example. Each of the steps 7, 8, 9 has the same height, and the height (h) obtained by subtracting the upper and lower plate thicknesses from the height matches the height of the four steps of the unit package 6. In FIG. 3, three lines 10 are drawn outside the respective steps 7, 8, 9 at a height position corresponding to h / 4. Since the first stage 7 is placed directly on the packing group 5, there is a top plate at the upper part, the lower part is in an open state, and there is an edge 11 that hooks the second stage outwardly horizontally in the lower four rounds. The upper stage and the lower stage of the second stage 8 are in an open state, and a hooking edge 12 is provided so as to be connected to the first stage horizontally inside the upper quadrant. There is an edge 13 that hooks the third step on the horizontal outer side of the lower quadrant. In the third stage, both the upper and lower parts are in an open state, and a catching edge 14 is provided so as to be connected to the second stage horizontally inside the upper four rounds. There is an edge 15 on the horizontal outer side of the lower quadrant, and the edge 15 is stably stored in the recess 16 of the packing device stability auxiliary member 3.

3 and 4 are enlarged cross-sectional explanatory views of the upper canopy packing device 2, the lower packing device stability auxiliary member 3, and the packing group 5. The size (b) of the upper edge of each of the second and third stages 8, 9 has the same length, and the size (c) of the lower edge of the first, second, and third stages also has the same length. The upper edge gap size of the first and second stages and the upper edge gap size (a) of the second and third stages have the same dimensions. Furthermore, the gap size (d) between the lower edges is the same dimension. The inclination angle A degree is also set to the same angle. The lower packing device stability assisting member 3 is a single sheet, but the upper canopy packing device 2 has a recess (t) lower in the position corresponding to the plate thickness at the position where the lower edge of the upper canopy packing device 2 is accommodated. The movement of 2 is regulated. In this example, a recess is provided only in the long side direction and the short side direction is cut off, but the long side direction can be extended to be the same as the short side.

In FIG. 4, the first stage 7 of the upper canopy packing apparatus 2 is covered with the packing group 5, and then the second stage 8 is covered while sliding outside the first stage 7, and the second stage upper edge 12 is formed. It overlaps with the lower edge 11 of the first stage and stops. Subsequently, while the third stage 9 slides in the same manner, the edges 13 and 14 of each other overlap and stop. At this time, the edge 15 is fitted in the recess of the lower packing apparatus stability auxiliary member 3. For this reason, the whole is stably packed.

FIG. 5 is an explanatory diagram of the short side showing the slide state, and 5-1 slides between the second stage 8 and the third stage 9 when the unit package 6 has 11 stages. During this time, one line applied to the outside disappears, and the number of lines represents 11 steps. 5-2 is a state in which the second stage 8 has completely reached the lower packaging device stability auxiliary member 3, and the unit packaging body 6 has exactly eight stages. 5-3 is a state where the first stage 7 and the second stage 8 are sliding, and 5-4 is a state where the first stage 7 has reached the lower packing apparatus stability auxiliary member 3. In this state, the unit package 6 changes to empty, but during this time, the first stage 7, the second stage 8, and the third stage 9 work together even if another returnable box type packaging device 1 is loaded on the upper part. It will be safe to support the load.

FIG. 6 shows a stacked height adjustment method. Contrary to the case of FIG. 4, the packaging group 5 is first installed from the third stage 9. Subsequently, the second stage 8 is stacked, and the edge 13 is positioned above the edge 14. Similarly, the first stage 7 is stacked, and the edge 11 is positioned on the edge 12. At this time, if the protrusions are provided so that the edges are tightly connected to each other, they can be firmly fixed. In addition, a material having sufficient strength must be selected. In this way, a gap of 4 t can be formed between the upper canopy packing device 2 and the inner packing group 5.

As an example of using this packing method, it can be used for packing a building material with a low noise countermeasure such as L40. In L40, a cushion material is stuck on the back surface of the plate to absorb noise, and there is a problem that the packing group 5 is inclined when the unit packing bodies 6 are stacked in a high number of steps. This can be used as a solution. If the height (h) of each step is reduced, fine adjustment can be performed. For example, when the height (h) corresponding to the four steps illustrated is set to the height (h / 2) corresponding to the two steps, the adjustment can be doubled.

FIG. 7 shows an example in which the stacking method and the sliding method are combined. When there are only two packing groups in the stacking method, the third step can be covered from the outside by the sliding method.

FIG. 9 is a developed view of the packing material of the invention of claim 2. The packing material 16 is used for packing building materials, and has a configuration of a long side portion 21, a short side portion 22, a long side portion 21, a short side portion 22, and a connecting piece 23 in order in the longitudinal direction. FIG. 10 is a simplified perspective view assembled and connected in an annular shape. FIG. 11 is an enlarged cross-sectional view of a bent groove shape. The packing material 16 is made of plastic, and two grooves 17 are formed in parallel along the longitudinal direction on the inner surface side, and the four folded portions are orthogonal to the folding grooves 17 at four positions. A groove 18 is formed. 11-1 of FIG. 11 shows the shape of the bending groove 17, and when the packing material 16 is extruded, this groove 17 is simultaneously formed with an elastomer having a thickness slightly smaller than the plate thickness of the packing material 16. 11-2 is located at the boundary between the long side portion 21 and the short side portion 22 of the packaging material 16, and the groove portion in which the back side of FIG. 10 is machined at a little over 90 degrees so that it can be bent inward by 180 degrees. It is an expanded sectional view. By providing these folding grooves 17 and 18, the packing material 16 can be folded at four locations in the longitudinal direction, and can be folded so that both side edges face each other in the folded state. In addition, notches 24 having a slightly greater than 90 degree are formed on both sides of the forming position of the bending groove 18, and notches 25 and 26 having a slightly more than 45 degree are formed on both sides of both end positions. Yes. Each of 27 is an extremely thin elastomer that is simultaneously molded on the outer surface side in parallel to the longitudinal direction, and serves as a slip stopper when plastics overlap each other. 11-3 is an enlarged cross-sectional view of the groove 19, and the side opposite to the groove 18 is machined at slightly over 90 degrees in the center of the short side portion. As a result, ninety-nine folds can be made at three locations, the groove 18, the groove 19, and the groove 18. This is used to fold the packing material 16 compactly. In addition, the packing material 16 has cutout portions 28 and 29 at both end positions, and is cut so as to be suitable for connecting the packing material 16 which is bent at four places in the longitudinal direction to form an annular shape at both ends. FIG. 12 shows an overlapping portion 30 when the cutout portions 28 and 29 are connected, and this overlapping portion 30 has a function of preventing loss.

FIG. 13 is a perspective view of one corner portion when the packing material 16 is used to pack a plate-shaped article 33, and a part of the long side portion 22 overlaps and presses the upper portion of the short side portion 21. Indicates the state. The notches 24 and 26 are notched slightly over 90 degrees or slightly over 45 degrees, but the long side portion 21 has a rising 31 at the end of the notch, and when this portion finishes packing, It becomes the overlap 32 of FIG. The short side is pressed to the long side by this overlap 32, and if the long side is pressed by the PP band, the short side will not come off.

FIG. 14 is a perspective view of the packing material 16 connected in an annular shape and folded inward on the short side so as to be in a compact state. Thus, if it becomes compact, since it does not exceed the length of a long side, it can be accommodated in the inside of the returnable box type packing body 1.

As the plastic material for forming the packaging material, an appropriate material can be used, but it is preferable to use a material having excellent bending resistance so as not to be damaged when repeated folding and folding. Polypropylene resin or the like is preferable so that the same can be simultaneously molded.
