This application is based upon and claims the benefit of priorities from Japanese Patent Application No. 2005-030375, filed Feb. 7, 2005, Japanese Patent Application No. 2005-079177, filed Mar. 18, 2005, and Japanese Patent Application No. 2005-309414, filed Oct. 25, 2005, the entire contents of which are incorporated herein by reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention The present invention relates to a technology for transporting and delivering articles.
2. Description of the Related Art
Apparatuses manufactured in factories transported and delivered to distributors or customers. For example, products like image forming apparatuses, such as copying machines, printers, and facsimile machines, are precious and delicate and need to be handled carefully during their transportation. The articles may be transported by trucks, freight trains, or ships. During transportation, the articles may be lifted many times or temporarily stored in warehouses. Therefore, some articles are designed so that they do not get damaged during transportation
Some products are once stored in a warehouse and then delivered to users. Others are directly delivered to a user from a factory. In any case, it is an important issue to protect the article from various external impacts and transporting environments, which the article undergoes during the transportation until it is delivered to the user and installed, and to deliver the article to the user without degrading its quality. That is, in the physical distribution process of the manufactured goods, it is desired to maintain the quality of the manufactured goods against vibrations and impacts generated when the goods are transported by transportation such as a truck, and external hazards (inertia and tilt due to a shift) generated by handling the goods at the time of reloading and storage performed at respective warehouse bases and working locations, and desired to provide package varieties having an effective function with respect to the transportability and loading/unloading work efficiency.
Conventionally, image forming apparatuses and the like are packed in a packaging material such as a cardboard box and delivered to users. This packaging material is opened by the user and stored as necessary, or disposed as a waste when it is not necessary.
In recent years, for resources saving, the packaging materials of various kinds of products such as image forming apparatuses are recycled. However, the conventional packaging material such as cardboard boxes has low durability, and is not suitable for using repeatedly for the transportation and storage of the products.
Furthermore, the conventional packaging material has to be prepared according to shapes and sizes different for each model, thereby causing a cost increase due to troublesome designing and management. In the case of a product such as an image forming apparatus, in which even in the same type, the size and the external shape become different due to the presence of optional devices, it is difficult to handle the product by a single type of a packaging material. Therefore, it can be considered to load the image forming apparatus on a pallet or a rack as described in Japanese Patent Application Laid-Open No. 2002-264815, and transport and deliver the apparatus.
The pallet and the rack can be reused, and can load thereon various types of products having different shapes and sizes. However, in the case of loading a heavy product such as a large-scale copying machine, the bottom plate of the pallet or the rack can be bent or deformed due to the impact when the product is loaded.
On the other hand, polyethylene terephthalate (PET) has an excellent impact resistance, and is light and used as a general-purpose plastic for industrial and household containers or the like. It is used as a familiar container known as “PET bottle”, and the production thereof is increasing as containers having the capacity of 500 milliliters, 350 milliliters, 330 milliliters, 200 milliliters, and the like. On the other hand, there is an issue of increasing plastic waste year after year, and the same is true for PET bottles. In other words, when the waste PET bottle is burnt, toxic substances are left in the burnt ashes after incineration.
Materials can be recycled in various ways. In material recycle, pellets are formed by crushing or grinding the waste without causing any chemical change, and are reused as a raw material. In thermal recycle, the waste is reused as a fuel for power generation combined with refuse incinerator. In chemical recycle, a resin is melted and dissolved to be returned to a chemical material, and is reused as a material. However, the recycling rate is not so high, and when the waste is finally disposed, the above problem will happen.
Another way is to wash the collected PET bottles reuse them. However, the time and trouble have to be taken for washing the bottles and the like, and with the continuously increasing number of PET bottles currently being used, this measure is not good enough for the waste PET bottles.
Japanese Patent Application Laid-Open No. 2002-002813 discloses a cushioning material for packaging arranged between an article to be packed and a case, to absorb impacts and an external force due to a pressing force. This cushioning material is arranged in a plurality of numbers on a flat board with cylindrical portions being parallel with each other, and includes a first bending groove provided on the flat board substantially in parallel with the cylindrical portion, at a position where the cushioning material is bent according to the size of the article to be packed, and a second bending groove with a V-shaped slit provided substantially at right angles to the cylindrical portion at a position where the cushioning material is bent according to the size of the article. The first and the second bending grooves are bent to cover the article, so that at least two cylindrical portions are brought into contact with each side of the article.
Japanese Patent Application Laid-Open No. 2001-335024 discloses another cushioning material for packaging configured such that necks of plastic bottles are inserted into a plurality of recesses of thin molded plastic materials, so that the thin molded plastic materials and the plastic bottles are fixed together and arranged between a to-be-packed member and a box.
Japanese Patent Application Laid-Open No. 2003-261179 discloses still another cushioning material for packaging arranged between a cardboard box and an article, and including paper sheet materials, and a plurality of paper pipes attached only to the surface of the peak of a fold of the sheet material. This cushioning material has paper pipes attached to a plurality of pipe mounting regions arranged via the folds.
Japanese Patent Application Laid-Open No. H9-267866 discloses a packaging body formed of laminated paper made of a material that can be easily disposed and has high recyclability, and using a cushioning member having a function of buffering effect. The cushioning member is attached to both sides of a container as a single piece or in a continuous block form corresponding to the gap between the container and the article.
Under such circumstances, the article to be transported is packed generally by forming the cushioning member according to the shape of the article, and under the current circumstances, the cost and time for the investment for equipment and the designing for the packaging material are required for each article. Furthermore, to perform such designing and management, the kinds of parts are increased, and the parts control is complicated accordingly.
Therefore, it is desired to handle various articles having different shapes with fewer types of cushioning materials, which can be used repeatedly. That is, such a form is desired that after the article is delivered to the user, the packaging device is returned to the factory or the like and used repeatedly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Exemplary embodiments of the present invention are explained below with reference to the accompanying drawings.
FIG. 1 is a perspective of an example of a packaging device 1 according to a first embodiment of the present invention. The packaging device 1 includes support members 2 arranged at four corners, and a frame member 3 that connects the support members 2 at the bottom. The support member 2 and the frame member 3 are made of iron, and the support members 2 and the frame member 3 are welding. Two adjoining support members 2 are connected by three crosspieces 4 above the frame member 3. The crosspiece 4 is also made of iron, and the support member 2 and the crosspiece 4 are connected by welding. A lattice-like rear member 6 is detachably fitted between the two support members 2 on the back. Reinforcing vertical-pieces 5 are provided parallel to the support members 2 that are connected by the crosspieces 4. The Reinforcing vertical-pieces 5 are connected between the frame member 3 at the bottom and the topmost crosspiece 4. The vertical-pieces 5 are also made of iron, and welded to the frame member 3 and the respective crosspieces 4.
The front side of the packaging device 1 can be opened for loading and unloading a product. That is, a front member 7 arranged between the left and right support members 2, 2 on the front side is supported rotatably by a shaft to the left and right support members 2 at the bottom part, and as shown by a broken line in FIG. 1, the front member 7 can be opened to the front side. When the front member 7 is opened as shown by the broken line, the front member 7 can be used as a slope when the product is unloaded. Locking devices 8, 8 for fixing the front member 7 to the left and right support members 2, 2 at the time of closing the front member 7 are attached to an external surface of the front member 7 (the lower surface when the front member 7 is used as the slope). While the rear member 6 can be fixed, in the first embodiment, it is detachably formed and can be detached, as required when unloading the product. Accordingly, the workability can be improved.
FIG. 2 is a cross section of the configuration near the bottom of the packaging device 1. A bottom base formed of the frame member 3 and a bottom plate 9 is provided near the bottom of the packaging device 1, and the frame member 3 is arranged so as to surround the four corners at the bottom of the packaging device 1. The bottom plate 9 is mounted on a receptacle of the frame member 3. The bottom plate 9 is made of iron and welded to the frame member 3 in the first embodiment. While it is assumed that the frame member 3 is an L-shape member in the example in FIG. 2, an optional material such as a flat plate or a tubular member can be also used.
In the configuration of the conventional packaging device, a product is loaded on the bottom plate. However, when a heavy product is loaded, there is a problem such that the bottom plate can be bent or deformed due to impacts when the product is loaded.
Therefore, in the packaging device 1 according to the first embodiment, a cushioning member is provided on the bottom plate 9, and a mounting base 21, which is a base plate for loading the product thereon, is placed on the cushioning member. According to the first embodiment, a reinforced plastic plate is used as the mounting base 21. Empty PET bottles 20 arranged as the cushioning member in the first embodiment. The PET bottles are wasted after the content drink or the like has been consumed. By using the PET bottles as the cushioning member, the cost required for the cushioning member can be largely reduced. Furthermore, the PET bottles 20 can be easily obtained. FIG. 3 depicts a state where the PET bottles as the cushioning member are arranged on the bottom plate 9. In FIGS. 2 and 3, the size of the PET bottles 20 is not necessarily scaled down according to the real ones, and only the state where the PET bottles arranged is shown. The arrangement, number, and the like can be optionally set.
If an impact is applied to the mounting base 21 when the product is loaded on the mounting base 21, or a heavy product, for example, a large-scale copying machine is unloaded, in the configuration in which the cushioning members arranged on the bottom plate 9 and the mounting base 21 is mounted thereon, the impact is dispersed by the cushioning members. Accordingly, it can be prevented that the mounting base 21 or the bottom plate 9 is bent or deformed.
In the packaging device 1 according to the first embodiment, as shown in FIG. 3, a reinforcing member 22 is arranged on the bottom plate 9. When the product loaded on the packaging device 1 is heavy, the product is generally very large. Therefore, the reinforcing member 22 is arranged below a region, where legs of the product (namely, casters of an image forming apparatus, because casters are normally provided when the product is the image forming apparatus) are placed when the product is loaded. That is, the reinforcing member 22 is arranged near the four corners of the mounting base 21 where product support members such as legs or casters of the product are situated.
According to the first embodiment, a double-cross shape reinforcing member 22 is arranged. The reinforcing member 22 is obtained by joining an iron square pipe steel to the bottom plate 9 by welding or the like in the first embodiment. The end of the reinforcing member 22 is joined to the frame 3 by welding or the like. In the packaging device 1 according to the first embodiment, the areas or regions where the casters or legs of the product are placed are shown by circles drawn by a one-dot chain line in FIG. 3. The number of the reinforcing members 22 in the vertical direction and the lateral direction is optional, and more reinforcing members 22 can be provided.
By arranging the reinforcing member 22, the deflection of the mounting base 21 or the bottom plate 9 at the time of loading the product decreases, as compared to the case that there is no reinforcing member 22. Accordingly, it is effective to prevent deformation or damage of the mounting base 21 or the bottom plate 9. Particularly, in the first embodiment, since the reinforcing member 22 is situated below the area (region), to which the product load is applied, it is effective to prevent deformation or damage of the bottom plate 9. Furthermore, since the reinforcing member 22 is situated in two directions (vertical and lateral directions) below the area (region), to which the product load is applied, deformation or damage of the bottom plate 9 can be prevented more reliably.
In the packaging device 1 according to the first embodiment, since the reinforcing member 22 is arranged between the PET bottles 20 as the cushioning member on the bottom plate 9, movements of the PET bottles 20 are suppressed by the reinforcing member 22, thereby efficiently preventing movements of the PET bottles 20 due to impacts when the product is loaded or impacts during transport.
For example, the PET bottles 20 can be arranged as shown in FIG. 3. The bottom of the PET bottles 20 is directed toward the center of the area, so that the caps of the PET bottles 20 are not placed in the area (region), to which the product load is applied. In other words, when the PET bottles 20 are used as the cushioning member in a transverse arrangement, the buffering effect is demonstrated not by the cap but by the body portion. Therefore, the bottle body portions with the buffering effect are arranged in the above area. In other words, by arranging the PET bottles 20 such that the caps are not in the above region, more reliable buffering effect can be demonstrated. Accordingly, even when a heavy product such as a large-scale copying machine is loaded on the packaging device, deformation and damage of the bottom plate 9 can be prevented by effectively dispersing the load applied from the casters of the large-scale copying machine, combined with the arrangement of the reinforcing member 22.
The PET bottles 20 can be arranged, with the longer side of the PET bottle 20 directed toward the vertical direction as shown on the right side in FIG. 3, or with the longer side of the PET bottle 20 directed toward the lateral direction as shown on the left side in FIG. 3, or can be arranged by appropriately combining the both.
FIG. 4 is a front view of a state where a product is loaded on the packaging device 1. A product 50 shown in FIG. 4 is a large-scale copying machine, and an automatic document feeder (ADF), which is an optional device, is mounted on top of the machine main unit. It can be seen that the product 50 has casters 51, and when the product 50 is loaded on the mounting base 21, the reinforcing member 22 is situated below the casters 51. A space 23, into which a forklift arm can be inserted, is formed between the frame member 3 and the floor. In the packaging device 1 according to the first embodiment, the space 23 is also formed on the left and right sides and the rear side, so that the forklift arm can be inserted from four directions of the packaging device 1.
Since the reinforcing member 22 is arranged in an installation space of the cushioning member between the bottom plate 9 and the mounting base 21, there is no increase in the height due to providing the reinforcing member 22, and the height from the floor to the mounting base 21 is suppressed, thereby facilitating the unloading operation of the product. In the packaging device 1 according to the first embodiment, the front member 7 is opened and used as the slope, which makes the inclination of the slope gentle, and facilitates the unloading operation of a heavy product.
A second embodiment of the present invention is explained next. FIG. 5 is a cross section of the configuration near the bottom of the packaging device according to the second embodiment. In a packaging device 1B according to the second embodiment, the reinforcing member 22 is joined (welded in the second embodiment) to the underside of the bottom plate 9. The basic configuration except this is the same as the packaging device 1 according to the first embodiment.
In the packaging device 1B according to the second embodiment, since the PET bottles 20 as the cushioning member are present on the reinforcing member 22, in addition to the same effect as that of the packaging device 1 according to the first embodiment, the load at the time of loading the product 50 on the mounting base 21 is dispersed more efficiently and applied to the reinforcing member 22. Accordingly, deformation and damage of the bottom plate 9 can be prevented more efficiently by the reinforcing member 22.
According to the second embodiment, since the reinforcing member 22 is provided on the underside of the bottom plate 9, the upper surface of the bottom plate 9 becomes a flat cushioning member arranging space having no obstacle. Therefore, the PET bottles 20 can be arranged without a gap on the bottom plate 9. FIG. 6 depicts (a part of) an arrangement example of the PET bottles 20 in the packaging device 1B according to the second embodiment. As shown in FIG. 6, the PET bottles 20 can be arranged without any gap in the area (region), to which the product load is applied, such that the caps are not arranged n the area. Therefore, the load at the time of loading the product 50′ on the mounting base 21 can be efficiently dispersed, and deformation and damage of the bottom plate 9 can be prevented more reliably by the reinforcing member 22.
A third embodiment of the present invention is explained next. FIG. 7 is a cross section of the configuration near the bottom of the packaging device according to the third embodiment. In a packaging device 1C according to the third embodiment, the reinforcing member 22 is joined (welded in the third embodiment) to the upper and lower surfaces of the bottom plate 9. The basic configuration except this arrangement is the same as that of the packaging device 1 according to the first embodiment.
The reinforcing member 22 on the upper and lower surfaces of the bottom plate 9 can be arranged at the same position in the vertical direction (so as to be overlapped as viewed in the vertical direction), or can be arranged at different positions (so as not to be overlapped as viewed in the vertical direction). In the example shown in FIG. 7, the reinforcing members 22 on the upper and lower surfaces of the bottom plate 9 are arranged so as not to be overlapped. Accordingly, the product load can be efficiently dispersed by the reinforcing member 22 on the upper and lower surfaces of the bottom plate. According to the third embodiment, since the reinforcing members 22 are provided on the upper and lower surfaces of the bottom plate 9, the strength of the bottom plate 9 is further increased, and even when a heavy product is loaded thereon, deformation and damage of the bottom plate 9 can be prevented more reliably.
As the arrangement of the PET bottles 20 according to the third embodiment, since there is the reinforcing member 22 on the upper surface of the bottom plate 9, the arrangement of the PET bottles 20 the same as in the packaging device 1 according to the first embodiment can be adopted. In the packaging device 1C according to the third embodiment, as shown in FIG. 7, since there is the reinforcing member 22 below the area (region), to which the product load is applied, deformation and damage of the bottom plate 9 can be prevented effectively. If the PET bottles 20 are arranged just below the casters 51 or the product legs, a better effect can be obtained by absorbing the impact.
In the second and the third embodiments, as in the first embodiment, by arranging the reinforcing member 22 in two directions (vertical and lateral directions) below the area (region), to which the product load is applied, deformation and damage of the bottom plate 9 can be prevented more reliably. The number and the arrangement position of the reinforcing member 22, or the shape and the material of the reinforcing member 22 can be appropriately set. The end of the reinforcing member 22 is joined to the frame member 3 by welding or the like in the respective embodiments.
The first to the third embodiments are not limited to the above arrangement, and for example, the material and the shape of the respective member can be optionally set. Furthermore, the number and the arrangement method of the PET bottles 20 used as the cushioning member are only an example, and the PET bottles 20 can be arranged differently from the example shown in FIGS. 3 and 6. The same applies to the number and the arrangement position of the reinforcing member 22 that reinforces the bottom plate 9. The reinforcing member 22 can be additionally provided so as to surround the circumference of the bottom plate 9 squarely.
FIG. 8 depicts an example in which the number of the reinforcing member 22 is increased so as to arrange the reinforcing member 22 also on the circumferential portion. In this example, the reinforcing members 22 are provided on the underside of the bottom plate 9. When the number of the reinforcing member 22 is increased, some of the reinforcing members 22 can be away from the underside of the area (region), to which the product load is applied. In the example shown in FIG. 8, the reinforcing members 22a to 22d are provided on the underside of the area (region).
The PET bottles 20 as the cushioning member can be square or circle. Cushioning members other than the PET bottles 20 can be also used.

In the fourth to the seventh embodiments explained below, the object to be loaded is a copying machine and the cushioning member is the PET bottles. However, the object to be loaded can be anything that requires a buffer with respect to vibrations, impacts, and the like. The cushioning member is not limited to the PET bottles, and various types of cushioning member can be employed, so long as it has the same or similar structure and effect. The cushioning member can be produced for exclusive use. The PET bottle has a bottle shape having a hollow part and a bottom, and is an airtight container having a body having at least one opening, and a closing body detachable from the opening of the body, which closes the opening.
There are various types as the PET bottles used as the cushioning member, including (1) bottles for carbonated beverages (cola, soda, and the like), (2) bottles for high-temperature filled beverages (fruit drink, sports drink, tea, coffee, and the like), (3) bottles for light carbonated beverages, which are subjected to sterilization after filling (light carbonated fruit drink or lactic drink), and (4) bottles for aseptic filling. Furthermore, the external shape or cross section includes circular, square (mainly a square shape with four corners rounded, or a deformed octagon obtained by cutting the four corners and then rounding all corners), and a mixed type of circle and square. Any of these can be employed for the PET bottles used as the cushioning member.
The bottle for carbonated beverages is referred to as a pressure resistant bottle and the like, which can endure internal pressure increased due to the gas generated from the beverages. The bottle for high-temperature filled beverages is used for a beverage not containing carbon dioxide, and is referred to as a heat resistant bottle and the like, whose neck can resist deformation due to the heat when the content is filled. The bottle for light carbonated beverages is referred to as a pressure and heat resistant bottle having both pressure resistant and heat resistant properties.

A sixth embodiment of the present invention is explained next. In the sixth embodiment, the packaging device 100 according to the fourth embodiment and the packaging device 200 according to the fifth embodiment pack the product 10 by using a buffer 300.
FIG. 21 is a perspective view of a packaging example using the buffer 300 according to the sixth embodiment. FIG. 22A is a perspective view of the buffer 300 shown in FIG. 21. FIG. 22B is a layout view of PET bottles 330 in the buffer 300 shown in FIG. 21.
FIG. 23 is a layout view of the PET bottles 330 in the buffer according to another example.
FIG. 24A is a perspective view of the buffer 300 according to another embodiment. FIG. 24B is a layout view of the PET bottle 330 in the buffer 300 according to the another example.
Although the bottles have been shown to be arranged with gaps therebetween in the figures, it is not limited to such arrangement. The bottles can also be arranged without any gap between vertically or horizontally adjacent bottles.
As the packaging device according to the sixth embodiment, the packaging devices 100 and 200 shown in the fourth and the fifth embodiments can be used.
According to the sixth embodiment, as shown in FIGS. 21, 22A and 22B, the buffer 300 arranged between the two transverse members of the packaging device 100 (200) and the product 10 is used as a packaging body. The buffer 300 is formed by arranging a plurality of PET bottles 330, which is an airtight container in which gas is sealed up in a hollow box-like member 310. The shape and the like of the PET bottle 330 is the same as in the fourth embodiment, therefore, the explanation thereof is omitted.
According to the sixth embodiment, the box-like member 310 is formed by notching and bending one plate made of synthetic resin, for example, a plastic cardboard material. The box-like member 310 includes, as shown in FIG. 22A, a bifacial outside corner contact portion 311, with which two inner surfaces of the packaging device 100 (200) with a box-like shape come in contact, and a bifacial inside corner contact portion 312, which comes in contact with a corner of the product 10, and is formed substantially in an L shape.
As shown in FIG. 25A, the box-like member 310 is formed substantially in an L shape by bending a box-like member having an opening 341 for bending at the center, before bending. According to the sixth embodiment, the box-like member is formed so that the PET bottles 330 can be inserted from the opening 341. In other words, according to the sixth embodiment, the PET bottles 330 can be inserted in two rows on one (α) side of the box-like member 310 divided at the center, two rows on the other (β) side, and one row in-between, and one row can accommodate three PET bottles. The box-like member 310 is then bent to form substantially an L shape, while protrusions h, I, and j formed on a surface α are inserted into slits l, m, and n on a surface β, and engaged therewith. At the time of bending, the PET bottles 330 in the middle row rotate, so that the other two rows on the opposite sides are lined up accordingly, so as not to move in pieces. Accordingly, the workability is not deteriorated.
Arrows shown on respective surfaces of the box-like member 310 shown in FIG. 25A indicate the direction of grain of the plastic cardboard material, and in the arrangement shown in FIGS. 21, 22A, and 22B, the direction of grain of the plastic cardboard material is vertical. Furthermore, as shown in FIG. 25B, after the assembly of the box-like member 310, there is a gap 342 between two plates constituting the corner of the L shape. Since there is a fold 343 on surfaces a and b of the box-like member 310, when it is pressed hard, the surfaces a and b bend as shown in FIG. 25. According to such a configuration, cushioning performance can be increased, while maintaining the strength of the buffer.
The box-like member 310 is made of plastic cardboard material. The box-like member 310 is formed by bending one plate material cut as shown in FIG. 26 according to a procedures (A) to (D):
(A) Bend the plate material, designating XY as an axis from the right toward the left in FIG. 26.
(B) Bond margins (shaded portions) on both sides together.
(C) Insert d between c and c at the top and the bottom in FIG. 26 so that these engage with each other.
(D) Insert the protrusion h on the b side into the slit l on the a side, insert the protrusion i on the b side into the slit m on the a side, and insert the protrusion j on the b side into the slit n on the a side.
The buffer 300 substantially in an L shape is completed in this manner.
The buffer 300 is then arranged in the packaging device 100 (200) so that the surfaces α and β abut on the corner of the product 10, with the surfaces a and b in FIG. 25A upward. At this time, as shown in FIGS. 25B and 25C, since the surfaces a and b can be bent, when the corner of the product 10 presses the surfaces α and β of the box-like member 310 due to vibration in the horizontal direction at the time of transport, the surfaces a and b of the buffer 300 bend, and the PET bottles 330 arranged in the buffer 300 reliably absorb the vibration of the product 10.
According to the sixth embodiment, to facilitate the replacement of the PET bottles 330, the protrusions h, I, and j are simply inserted into the slits l, m, and n and not bonded together. Therefore, when the corner of the product 10 presses the surfaces α and β of the buffer, a force of the protrusions h, I, and j slipping out from the slits l, m, and n is applied. Particularly, when the box-like member 310 is arranged longitudinally, the protrusion h located at the top can slip out. In the sixth embodiment, to prevent this, the buffer is formed in the following manner, from (E) to (H):
(E) The protrusion h has a longer length toward the slit insertion direction, as compared to the length of other protrusions I and j.
(F) An engagement portion 345 of the protrusion h, which is hooked by the internal circumference of the slit l, is formed in a curved shape, and the left end of the protrusion h is located on the left side of the left guide hole of the slit l.
(G) The height of the slit l is made higher than that of the slit m.
(H) Right guide holes of the slits l, m, and n are extended toward the right further than the right end of the protrusions h, i, and j.
In FIG. 26, the protrusions h, i, and j are inserted into the slits l, m, and n, while shifting the protrusions h, i, and j toward the right. When the hand is released, the protrusions tend to return to the left side in FIG. 26. The engagement portion 345 at the left end of the protrusion h enters into the inside of the slit l from the left end guide, and engages with and overlaps on the slit in the left and right direction in FIG. 26. As a result, even if the buffer 300 is arranged with the protrusion h being upward, since the engagement portion 345 engages with the slit l, slipping out of the protrusion from the slit can be prevented.
According to the sixth embodiment, the PET bottles 330 are arranged in the same direction longitudinally as shown in FIG. 22B, or alternately in the opposite direction as shown in FIG. 23 so that the bottle portions 330a and the caps 330b of the PET bottles, respectively, come in contact with each other as shown in FIG. 23. The PET bottles can be arranged laterally, instead of longitudinally as in this example. At this time, by making the longitudinal direction of the PET bottles 330 and the grain of the plastic cardboard material parallel to each other, the product 10 is buffered both by the hollow portion constituting the grain and the hollow portion of the PET bottles. Accordingly, the impact of the product 10 can be buffered.
To use the buffer 300 according to the sixth embodiment, as shown in FIG. 21, the buffer 300 is put between the corner of the product 10 and the corner of the packaging device 100 (200), and the product 10 is pressed by a packaging belt.
While the buffer 300 is substantially in the L shape in the sixth embodiment, as shown in FIGS. 24A and 24B, a buffer 400, in which PET bottles 430 are arranged in a thin rectangular box-like member 410, can be arranged between the product and one surface of the packaging device 100 (200). Also in this case, the arrangement pattern of the PET bottles 430 can be variously changed.
A seventh embodiment of the present invention is explained next.
FIG. 27 is a side view of a bottom base 210 of a packaging device 600 according to the seventh embodiment.
FIG. 28A is a plan view of a top panel member 610 of the packaging device 600 according to the seventh embodiment. FIGS. 28B and 28C are side views of the top panel member 610 of the packaging device 600 according to the seventh embodiment.
FIGS. 29A, 29B, and 29C are, respectively, a front view, a plan view, and a side view of the upper transverse member 240 of the packaging device 600 according to the seventh embodiment.
FIGS. 30, 31, and 32 are, respectively, a front view, a back view, and a plan view when the top panel member 610 in the packaging device according to the seventh embodiment is mounted.
The schematic configuration of the packaging device 600 according to the seventh embodiment is the same as that of the packaging device 200 according to the fifth embodiment, except that the top panel member 610 can be slid and detached. Therefore, like parts are denoted by like reference numerals, and the explanation thereof is omitted.
In the top panel member 610 of the packaging device 600 according to the seventh embodiment, the frame 284 includes the engagement member 287, as in the top panel member 280 shown in FIGS. 20A and 20B, and is engaged with the fitting guide 248 of the upper transverse member 240 by placing the top panel member 610 from above, with the position thereof adjusted with respect to the fitting guide 248. In this case, since the top panel member 610 is made of steel, it is not easy for one worker to lift the heavy top panel member 610 upward horizontally and position the engagement member 287 to the fitting guide 248. However, according to the seventh embodiment, even one worker can position the top panel member 610 with respect to the body of the packaging device 600.
In the top panel member 610 according to the seventh embodiment, as shown in FIGS. 28A, 28B, and 28C, a guide 612 is provided on the frame body 283, which slides on a sliding guide 622 (see FIGS. 29A and 29C) provided on the upper pillar member 241 of the upper transverse member 240. According to the seventh embodiment, a locking protrusion 611 that engages with a hole 623 provided at a predetermined position of the sliding guide 622 is provided at the opposite ends of the frame 284. Furthermore, as shown in FIG. 29B, the hole 623 is provided at the opposite ends of the sliding guide 622, so that the frame 284 of the top panel member 610 can be slid from the left to the right in FIG. 29A, and fitted to the hole 623 in the sliding guide 622, both on the front side and the other side of the packaging device 600.
According to this configuration, the worker places one side of the guide 612 or the locking protrusion 611 on the guide face of the sliding guide 622 on the front side of the packaging device 600, slides the top panel member 610 toward the other side of the packaging device 600 along the sliding guide 622, to guide the top panel member 610 to the position engaging with the hole 623 in the sliding guide 622, and thereafter, engages the locking protrusion 611 with the hole 623 to fix the top panel member 610.
The position in the height direction of the sliding guide 622 is set such that it is higher than the upper face of the front member 250 on the front side of the packaging device 600 as shown in FIG. 30, and on the rear side of the device 600, as shown in FIG. 31, the upper face of the rear member 270 and the lower face of the top panel are at the same position. According to the seventh embodiment, as shown in FIGS. 30 and 31, a belt engaging hole 650 is opened, respectively, in the corner plate 236 for reinforcement.
A protrusion 613 is provided, as shown in FIG. 28C, above of the frames 284 and 283, so that it is prevented that an article placed on the top panel (for example, a box or the like that packs attachments of the product to be mounted on the mounting base 180) falls from the packaging device 600, for example as shown in FIG. 32, in the state that the top panel member 610 is fitted.
Furthermore, as shown in FIG. 27, the belt fixing unit 219 that fixes a belt 640 used for preventing misregistration of the product 10 mounted on the mounting base 180 is provided on the lower transverse member 230 and the upper transverse member 240 at the rear side of the packaging device 600.
When the product 10 is packed using the packaging device 600 according to the seventh embodiment, the product 10 wrapped in a bag (of a reusable or recyclable material) is mounted on the mounting base 180, and as shown in FIG. 33A, the buffer 300 explained in the sixth embodiment is arranged respectively at the left and right corners on the other side, and the left corner on the front side. At the other corners, the second plate-like buffer 630 made of polypropylene or the like is arranged, and fixed by two belts 640 as shown in FIG. 33B. The one end of the belt 640 is hooked to the belt fixing unit 219, and the other end is hooked to the frame on the front side, as shown in FIG. 33B. The reason why the second buffer 630 is provided in this manner is that the force of the belt 640 is directly applied to this corner, and the box-like member 310 can be greatly damaged.
Thus, the product 10 is mounted on the mounting base 180, positioned by two sides, of the four sides, pressed against the two sides, and fixed by the belt 640.
The opening procedure is explained below based on FIGS. 34A to 34F. At first, a box 700 mounted on the top panel member 610 is brought down (FIG. 34A). The locking protrusion 611 of the top panel member 610 is removed from the hole 623 in the sliding guide 622, and the top panel member 610 is pulled out toward the front side of the packaging device 600, and detached (FIG. 34B). The lock of the locking device 290 on the front member 250 is released, and the front member 250 is inclined toward the front side (FIG. 34C). The belt 640, the buffer 300 on the front side of the packaging device 600 and the second buffer 630 are detached (FIGS. 34D and 34E), and the product 10 is unloaded using the slope made by the front member 250, thereby finishing unpacking (FIG. 34F).
After the unpacking is finished, in a case that an old copying machine is collected from the delivery destination, the old machine can be packed and collected by tracing back the above procedure. As an example, it is assumed that there is no product to be collected at the delivery destination, and only the packaging device 600 is collected. As shown in FIGS. 35A to 35D, the rear member 270 and the upper transverse member 240 are pulled upward (FIG. 35A). The front member 250 is then folded onto the mounting base 180, and the rear member 270, the upper transverse member 240, and the top panel member 610 are overlapped thereon (FIG. 35B). The two buffers 300 are arranged back to back and one buffer 300 is further arranged with a space therebetween on the overlapped members, and the box 700, which has been mounted on the top panel, is arranged between the buffers. In this box, the second buffer 630 can be housed, and the bag, which has wrapped the product 10, can be folded and housed as well (FIG. 35C). Lastly, the belt 640, which has positioned the product 10 is locked and fixed to the belt engagement hole 650 (FIG. 35D). Thus, a plurality of members constituting the packaging device 600 can be reliably collected in a compact manner, without causing a drop.
According to the seventh embodiment, the front member 250, the upper transverse member 240, the top panel member 610, and the rear member 270 are formed in a size housed within the surface of the mounting base 180. These members are overlapped on each other, and the uppermost position when the buffer 300 and the box 700 are further overlapped thereon is equal to or lower than the position of the beam 237. When the two buffers 300 back to back and the other one buffer 300 are arranged with a space therebetween, and the box 700, which has been mounted on the top panel member 610, is arranged in the space, the length between the ends of the buffers 300 is smaller than the width of the mounting base 180, or smaller than the width of the front member 250, the upper transverse member 240, the top panel member 610, and the rear member 270. Accordingly, these members can be locked by the belt 640 and reliably collected without falling down from the packaging device 600.
According to this configuration, an excess space is not created, and even the box 700 for carrying the attachments to be mounted on the top panel member 610 can be placed within the packaging device 600. As a result, the collection efficiency can be improved. At the time of collection, the legs 261 and 263 are mounted on the guide plate 235 of the beam 237 of the folded packaging device 600, overlapped and collected, thereby realizing space saving of the packaging device 600. The assembled packaging device 600 can be piled up.
Although the invention has been described with respect to a specific embodiment for a complete and clear disclosure, the appended claims are not to be thus limited but are to be construed as embodying all modifications and alternative constructions that may occur to one skilled in the art that fairly fall within the basic teaching herein set forth.
