Description

  The present invention relates to a roller packaging container (hereinafter, also simply referred to as “packing container”) used when transporting a roller such as an OA roller.

  Among office automation equipment (OA equipment), various roller members such as a toner supply roller, a transfer roller, and a cleaning roller are used in an image forming apparatus using an electrophotographic method such as a copying machine, a printer, or a facsimile. . The OA roller, which collectively refers to these various roller members, has a basic structure in which a cylindrical roller body is provided on the outer periphery of the shaft. Among them, the roller body is usually composed of an elastic layer made of a resin foam such as polyurethane foam, and one or more functional layers formed on the elastic layer.

  When handling the OA roller, contact with other things in the functional layer, deformation, dust on the surface, etc. in the transport process after manufacture until it is incorporated into the image forming apparatus, in order not to impair various performances at the time of manufacture. It is important to prevent the adhesion of foreign matter and the like. For this reason, the packing container for OA roller used at the time of conveyance of OA roller is required to have the ability to prevent intrusion of foreign matter from the outside while holding the OA roller without contacting the functional layer. In addition, considering that the OA roller itself is an inexpensive product, it is also important that the cost for manufacturing and transporting the packaging container itself is low.

  On the other hand, for example, Patent Document 1 discloses a container integrally formed of a synthetic resin, including a housing portion having a recess forming a depth surrounding the OA roller, and a side wall portion provided around the housing portion. A plurality of containers whose side wall portions are different from each other can be vertically stacked, the container of each container has a support portion for supporting the shaft of the OA roller, and the side wall of each container is A hollow shape having a flange connected to the upper end of the part and an outer wall extending downward from the outer end thereof, wherein at least two opposing sides across the housing part have a bottom in the vertical middle of the outer wall A packaging container for an OA roller is disclosed which has recesses and which are formed at different positions on corresponding side walls of the upper and lower containers.

JP, 2013-173566, A (the claim etc.)

  According to the packing container described in Patent Document 1, when the pair of containers containing the OA roller are stacked in the vertical direction, the upper container functions as a lid of the lower container, so a lid is separately provided from the container. It is not necessary to prepare the container, and the cost for the lid can be reduced. Therefore, it is possible to improve the cost while securing various performances required for the packaging container. However, this packaging container has a drawback that the container itself is bulky because it is made of a hard synthetic resin, and a further improvement is also required in terms of cost during manufacturing and transportation.

  Therefore, an object of the present invention is to provide a packaging container for a roller, in which the container itself is simplified while securing various properties required for the packaging container, and the cost properties at the time of manufacturing and transport are further improved.

  As a result of intensive investigations, the inventor of the present invention has found that the above-mentioned problems can be solved by the following constitution, and the present invention has been completed.

  As illustrated, the roller packaging container 10 of the present invention is used for packaging a roller 13 having a cylindrical roller main body portion 11 and a pair of shaft portions 12 provided at both axial end portions thereof. is there. The packaging container of the present invention is mainly composed of a film-like body 1 made of a soft material, that is, it can be flexibly deformed, and rollers and gas can be enclosed inside the container, and inside the container, There is at least one storage room 2. Further, in the packing container 10 of the present invention, the storage chamber 2 includes a roller storage portion 2A in which the roller body portion 11 of the roller 13 is stored, and a pair of shaft holding portions for holding the pair of shaft portions 12 of the roller book 13. And 2B. Here, in the illustrated example, the storage chamber 2 is formed in a substantially cylindrical shape corresponding to the roller shape, but in the present invention, the shape of the storage chamber is not limited to this.

Furthermore, in the packaging container 10 of the present invention, as illustrated, when the roller 13 is stored in the storage chamber 2, the surface of the roller 13 is covered with gas, and the surface of the roller 13 and the storage chamber 2 are It does not come in contact with the surface. That is, in the present invention, for example, as illustrated, when the storage chamber 2 has a substantially cylindrical shape, the roller body of the roller 13 in which the minimum inside diameter r _min of the roller storage portion 2A of the storage chamber 2 is stored. When the roller 13 and the gas are enclosed in the storage chamber 2 of the packaging container 10 and the roller 13 is fixed by the shaft holding portion 2B, the roller of the roller 13 is formed. A space S filled with gas is present between the outer peripheral surface of the main body 11 and the inner peripheral surface of the roller housing 2A of the packaging container 10. In the packing container 10 of the present invention, the outer peripheral surface of the roller main body 11 of the packed roller 13 is covered with the gas as described above, whereby the functional layer of the roller contacts with other things during transportation. And does not cause deformation or foreign matter on the surface. The thickness of the space between the surface of the roller 13 and the surface of the storage chamber 2 can be, for example, 1.5 mm or more, preferably 2.0 to 4.0 mm. By securing the thickness of this degree, it is possible to reliably protect the surface of the roller at the time of conveyance while suppressing the conveyance cost.

  In addition, the packaging container 10 of the present invention is formed mainly of the film-like body 1 made of a flexible soft material, and has a bag-like structure capable of packaging rollers one by one as illustrated. Because it is lightweight itself, it is not bulky like conventional multi-pack packaging, and can be transported with the required number of spaces and costs, and the transport weight is also light. Manufacturing costs and transportation costs can be significantly reduced.

  Furthermore, in the packing container 10 of the present invention, only the shaft portion 12 of the roller 13 is held and the roller 13 is fixed in the storage compartment 2 divided into one by one container. There is no such thing. Further, in the packaging container 10 of the present invention, by sealing the gas together with the roller 13 in the storage chamber 2, the gas plays the role of a shock absorbing material, so the load resistance can be improved, and the packaging container can be used. Even when an external load is applied, it is possible to prevent the adhesion and damage of foreign matter and the like to the stored roller 13. In particular, in the case where the roller body 11 is a toner supply roller or the like formed of resin foam, when the roller body 11 is deformed by an external load, a compressive residue remains even after the load is removed. The application of the present invention is useful because distortion may occur.

  The load resistance of the packaging container of the present invention is preferably 50 kgf (490N) or more, preferably 500 kgf (4900N) or more, from the viewpoint that no influence is exerted on the packaged roller.

  Furthermore, since the packaging container 10 of the present invention has a bag-like structure made of a soft flexible material, it is cheaper than the conventional packaging container made of hard resin in terms of material cost in addition to manufacturing and transportation costs. is there. In addition, since it is in the form of a sheet and can be folded and stored before and after use, it is extremely excellent in terms of transportability and handleability in the non-used state, and space saving at the time of storage. Furthermore, the final waste volume can also be reduced compared to conventional packaging.

  Furthermore, the packaging container 10 of the present invention has a bag-like structure, and the container is housed in a container with the roller housed therein and filled with gas, so that the container is used with the container sealed. It is possible to prevent intrusion of foreign matter, moisture and the like from the outside, and it is also possible to obtain the merit of being able to suppress deterioration of the roller due to adhesion of foreign matter and the like and penetration of moisture. In addition, since gas intervenes between the external environment and the roller, there is also an advantage of being less susceptible to external temperature (heat) and vibrations.

In FIG. 2, (a) an axial direction partial cross-sectional view of a state in which the roller is accommodated in the packing container according to another embodiment of the present invention, (b) a cross section in a direction orthogonal to the axial direction along line B-B. The figure and (b) sectional drawing of the direction orthogonal to an axial direction in alignment with a CC line are shown, respectively. In the present invention, as in the illustrated packaging container 20, the inner diameter r _{e at} both axial ends of the substantially cylindrical storage chamber 22 at the portion corresponding to the roller housing 22A is the axial direction of the roller housing 22A. Preferably, it is formed larger than the inner diameter r _{c at the} central portion. As a result, the axial end of the roller body 11 of the roller 13 can be more reliably prevented from coming into contact with the surface of the storage chamber 22 of the packaging container 20, and the surface of the roller body 11 is marked. Can be suppressed. In addition, the code | symbol 21 in a figure shows a membranous body.

  The shape of the shaft holding portion in the present invention is not particularly limited as long as it can be held and fixed near the axial center of the substantially cylindrical storage chamber. . For example, in the example shown in FIGS. 1 and 2, the holding portions 2B and 22B have a V shape in at least one cross section parallel to the direction connecting the pair of shaft holding portions in the storage chamber. Thus, the shaft holding portion can be provided with the simplest shape. In addition, by forming the shaft holding portion in a V shape, the shaft portion naturally has a V shape even when the roller is packaged with the shaft portion slightly deviated from the central axis of the substantially cylindrical storage chamber. The error is tolerable as it moves towards the corners of the.

  In FIG. 3, (a) a partial axial sectional view and (b) along a line DD, which are orthogonal to the axial direction, in a state in which the roller is accommodated in the packing container according to still another embodiment of the present invention. The sectional views of the directions are shown respectively. In the example shown in FIG. 3, in at least one cross section of the storage chamber 32 parallel to the direction connecting the pair of shaft holding portions 32B, the shaft holding portion 32B has a substantially U shape. This makes it possible to hold the shaft most reliably. Further, by making the shaft holding portion substantially U-shaped, there is a space in which gas enters the corner 33 of the axial end of the roller storage portion 32A of the storage chamber 32, so that the axial end of the roller main body 11 Can be more reliably prevented from coming into contact with the surface of the storage chamber 32 of the packaging container 30, and the surface of the roller main body 11 can be prevented from being scratched. Here, in the present invention, substantially U-shaped means substantially a shape in which a U-shaped bent portion is close to a right angle corner as shown in the drawing. In addition, the code | symbol 31 in a figure shows a membranous body.

  FIGS. 4 and 5 each show an axial partial cross-sectional view in a state where the roller is accommodated in the packing container according to still another embodiment of the present invention. The packaging container of the present invention is, as shown in FIGS. 1 to 3, provided with one storage chamber per packaging container and packaging one roller, as shown in FIGS. 4 (a) and 4 (b). As shown, a plurality of storage chambers 42 and 52 may be provided for each packaging container 40 and 50, and in the illustrated example, four rollers 14 may be packaged. . In the present invention, the number of storage chambers is not particularly limited, and may be, for example, about 1 to 20. In the drawings, reference numerals 41 and 51 denote film-like bodies, 42A and 52A denote roller accommodating portions, and 42B and 52B denote shaft holding portions. Furthermore, as shown in FIGS. 5 (a) to 5 (d), the packaging container of the present invention can be used by being connected in a plurality, and in this case, gas can be applied to a plurality of packaging containers at one time. While being able to inject | pour, there exists a merit that handling is easy because it is arranged in a row.

  In FIG. 6, the axial direction fragmentary sectional view of the state which accommodated the roller in the packing container which concerns on other embodiment of this invention is shown. As illustrated, the packaging container 60 of the present invention may be made of a tubular film-like body 61 made of a soft material. In the figure, reference numeral 61 denotes a film-like body, 62 denotes a storage chamber, 62A denotes a roller storage portion, and 62B denotes a shaft holding portion.

  The soft material constituting the film-like body 1 of the packaging container of the present invention is not particularly limited as long as it can be flexibly deformed at the time of use. For example, general-purpose thermoplastic resins can be used, and specifically, polyethylene, polyamide, polyvinyl chloride, polyvinylidene chloride, polypropylene, polyester, polycarbonate, polystyrene, polyacrylonitrile, ethylene vinyl acetate copolymer, ethylene -Films of vinyl alcohol copolymers, ethylene-methacrylic acid copolymers and polymer alloys thereof, cellophanes, multilayer films thereof and the like can be used, and among them, polymer alloys of polyamide and polyethylene are preferably used. it can. In the present invention, by using a material having high airtightness as the soft material, the influence of moisture entering from the outside can be more effectively suppressed, and by using a material having high heat shielding, the outside can be prevented. The effects of heat from the material can be reduced more effectively, and the use of materials with high light shielding properties can reduce the effects of external light (ultraviolet light) more effectively, and it is water resistant. Environment resistance can be improved according to the use environment of a packing container by selecting the kind of material appropriately, such as being able to suppress the strength fall of the packing container by moisture, by using a high material. .

  In addition, the thickness of the film-like body 1 is such that the packaging container 10 does not deform when the inside of the container is filled with the pressurized gas or when a load is applied from the outside. For example, the thickness is preferably 30 μm or more, preferably about 60 to 120 μm. The larger the thickness is, the load resistance of the packaging container is improved. On the other hand, when the thickness is too large, the costability and the transportability are reduced, so the thickness within the above range is preferable.

  Further, in the packaging container of the present invention, the gas filled inside the container together with the roller is not particularly limited, and in addition to air, an inert gas such as nitrogen can also be used. In particular, the use of an inert gas is preferable because oxidation deterioration of materials such as polyurethane foam constituting the roller can be prevented. In the present invention, the pressure of the gas injected into the inside of the container is preferably 0.03 MPa or more, and preferably about 0.06 to 0.10 MPa.

  The packaging container of the present invention as shown in FIGS. 1 to 5 can be easily manufactured by superposing a pair of sheet-like film-like bodies and joining the outer peripheral portion according to the shape inside the container. . As a bonding method, for example, in the case of using a thermoplastic resin as a soft material, heat seal (heat seal) can be used. In this case, for example, first, a pair of film-like bodies are overlapped, and the bag-like body is manufactured by joining the outer peripheral portion except the one end side in the axial direction according to the shape inside the container. After sealing the roller and the gas inside the container from the opening on the side, the roller at the opening on one end side in the axial direction is also joined according to the final shape of the inside of the container, so that the roller is A packed package can be obtained. In the case of packing a plurality of rollers in one packing container, for example, while blowing gas into the container, the formation of the shaft holding portion by joining the film-like members and the storage of one roller are alternated. Can be repeated. In addition, the present invention can also be achieved by processing into a target container inside shape using a commercially available air buffer material, a product made by Mars Co., Ltd. or an air chain made by Affinity Package Co., Ltd. You can get the packing container of

  Further, in the case of the packaging container of the present invention as shown in FIG. 6, a soft material is used to form a tube-like film-like body, and gas is blown into the inside of the obtained tube-like film-like body However, packing of a plurality of rollers can be performed by alternately repeating the formation of the shaft holding portion by joining the film-like members and the storage of one roller. On the other hand, since the removal of the roller from the packaging container of the present invention can be easily performed by making a hole in the packaging container, the packaging container of the present invention also has the merit of high unpacking workability. .

  Further, in the packaging container of the present invention, it is preferable to provide a check valve for preventing the backflow of the gas injected into the container at one axial end of the shaft holding portion. Thereby, the workability at the time of packing can be improved.

  The packaging container of the present invention can be suitably applied to various OA rollers such as a toner supply roller, a transfer roller, and a cleaning roller used in an image forming apparatus, and is not particularly limited.
