  By the way, the surface characteristics (surface roughness, contact angle, flatness, gloss, etc.) of the functional belt are closely related to the image quality to be formed. There is a problem that tends to be a defect.

  In particular, in recent years, the demand for high image quality has increased, and the tolerance level of functional belts such as rubbing scratches and dirt has become stricter than before.

  However, all of the belt packing methods (belt packing containers) disclosed in the above cited documents 1 to 3 are such that the packing material or the container contacts the outer peripheral surface (surface) of the belt, or the belt outer peripheral surfaces contact each other. For this reason, there is a problem that the packing material, the packing container itself, or the outer peripheral surfaces of the belt cause the surface to be scratched or stained.

  Further, in the stationary storage after packing the belt, permanent distortion due to the contact pressure of the packing material or the packing container or transfer of contaminants from the packing material occurs, which is also likely to cause problems such as image defects.

  Accordingly, in view of the above problems, the present invention prevents a belt and a packing container for a belt capable of preventing rubbing scratches and contact marks generated on the outer peripheral surface of the belt during a packing operation and transportation / storage process, and preventing permanent distortion due to packing. An object is to provide a method of packing a belt.

The above problem is solved by the following means. That is,
The belt packing container of the present invention is a belt packing container in which the outer peripheral surfaces of the belt are packed in a non-contact manner,
A container body that covers the belt in a non-contact manner with respect to the outer peripheral surface thereof;
A belt movement restricting member that is disposed inside the belt to be packed and restricts movement of the belt in contact with an end face and / or inner peripheral surface of the belt;
It is characterized by having.

  In the belt packaging container of the present invention, the belt movement is restricted by the belt movement restricting member being brought into contact with the end surface and / or the inner peripheral surface of the belt, and the belt whose outer peripheral surfaces are not in contact with each other by the container main body. Pack without contact with the outer peripheral surface. Thus, the outer peripheral surface of the belt is not in contact with the packaging container, and only the end surface and / or the inner peripheral surface of the belt is in contact with the packaging container and packed. For this reason, it is possible to prevent rubbing scratches and contact marks generated on the outer peripheral surface of the belt during the packing operation and transportation / storage process, and it is possible to prevent permanent distortion due to packing.

  In the belt packaging container of the present invention, it is preferable that the belt movement restricting member is arranged to stretch the belt to be packed. This substantially eliminates movement of the belt in the packing state, more effectively prevents rubbing scratches and contact marks generated on the outer peripheral surface of the belt during the packing operation and transportation / storage process, and prevents permanent distortion due to packing. be able to.

  In the belt packaging container of the present invention, it is preferable that the belt movement restricting member is formed integrally with the container body. Thereby, cost reduction of packaging container itself can be achieved.

  In the packing container for a belt according to the present invention, the first container body that covers one end side in the axial direction of the belt in a non-contact manner with respect to the outer peripheral surface of the belt, and the first container so as to be positioned inside the belt to be packed. A first belt movement restricting member that protrudes from the bottom surface of the container main body and restricts movement of the belt by abutting against one end surface in the axial direction of the belt and / or an inner peripheral surface on the one end side; A second container body that covers the other end side in the axial direction in a non-contact manner with respect to the outer peripheral surface of the belt, and is disposed so as to protrude from the bottom surface of the second container body so as to be positioned inside the belt to be packed, It is preferable to have a second belt movement restricting member that restricts movement of the belt in contact with the other axial end surface of the belt and / or the inner peripheral surface on the other end side. Thus, by dividing the packing container into two members, the packing operation is facilitated and the opening is also facilitated.

  The first belt movement restricting member and the second belt movement restricting member may be formed such that a maximum length when cut in parallel with the bottom surface of the container gradually decreases in the protruding direction. Thereby, the belt movement distance by the belt movement regulating member can be shortened (or eliminated), and insertion into the belt movement regulating member is facilitated.

  The belt packaging container of the present invention is preferably subjected to antistatic treatment. This makes it difficult for the contaminants (dust) such as dust to adhere to the packaging easily, and as a result, the contaminants hardly adhere to the outer peripheral surface of the belt.

On the other hand, the belt packing method of the present invention is a belt packing method in which the outer peripheral surfaces of the belt are packed in a non-contact manner,
The belt is packed in a non-contact manner with respect to the outer peripheral surface of the belt while restricting movement of the belt in contact with the end surface and / or the inner peripheral surface of the belt.

  In the belt packing method of the present invention, as described in the belt packing container of the present invention, the outer peripheral surfaces of the belts do not contact each other, and only the end surface and / or the inner peripheral surface of the belt are in contact with the packing container. Since the bell is packed, it is possible to prevent rubbing scratches and contact marks generated on the outer peripheral surface of the belt during packing work and transportation / storage, and to prevent permanent distortion due to packing.

Positioning is performed by fitting the convex portion 14D and the concave portion 14E to the convex portion and concave portion for positioning provided on the upper surface of the restricting portion of the second container body 20, respectively.

  The second container main body 20 is substantially the same as the first container main body 10, and a three-view drawing is omitted. As shown in FIG. 2, the second container main body 20 includes a rectangular bottom plate 21 and side plates 22 connected to the four sides thereof. It is configured. Further, edge plates 23 are connected in parallel with the bottom plate 21 to the sides of the side plates 22 facing the connecting portion of the bottom plate 21. The connecting portion between the edge plate 23 and the other edge plate 23 is provided with a convex portion 23A and a concave portion 23B for alignment, and the alignment convex provided at the connecting portion at the edge portion of the first container body 10. Positioning is performed by fitting each of the portion and the recess. The bottom plate 21 is provided with a reinforcing groove 21A.

  On the surface of the bottom plate 21 of the second container body 20, a belt movement restricting member 24 that protrudes in a direction perpendicular to the surface of the bottom plate 21 in a space surrounded by the side plate 22 is integrally formed. The belt movement restricting member 24 is disposed so as to be inserted into the belt 30 to be packed, and its outer wall is in contact with the end surface (one end surface) and the inner peripheral surface, thereby restricting the movement of the packed belt. Is. In the present embodiment, since three belts 30 are packed, three corresponding belt movement restricting members 24 are also provided.

  The belt movement restricting member 24 is composed of two head-on-cone-shaped (trapezoidal cross-section) restricting portions 24A and 24B and a rectangular parallelepiped connecting portion 24C that connects them. With this configuration, the belt movement restricting member 24 has its maximum length (maximum length when cut in parallel with the bottom plate) gradually decreasing from the bottom (connecting portion with the bottom plate 21) toward the top. It is comprised so that it may become. Further, the two restricting portions 24A and 24B are spaced apart so as to be able to contact and stretch on the end surface and the inner peripheral surface of the belt 30 at the bottom wall surface.

  The 1st container main body 10 and the 2nd container main body 20 can be shape | molded by carrying out the vacuum molding process of plastics (for example, thermoplastic resins, such as a polypropylene, a polystyrene, or a polyethylene terephthalate). Thereby, a container and a belt movement control member can be integrally molded, and cost reduction can be achieved. In particular, polystyrene has a good balance between moldability and cost, and is suitable as a packaging container material for an electrophotographic functional belt.

  The first container body 10 and the second container body 20 are subjected to antistatic treatment. Specifically, for example, known antistatic agents (for example, cationic surfactants, anionic surfactants, amphoteric surfactants, nonionic surfactants, etc.) can be used. As an amphoteric surfactant, an electrostripper AC manufactured by Kao Corporation) is applied to the antistatic treatment. Alternatively, known antistatic agents (for example, in addition to the above-mentioned ones, conductive metal oxide particles, carbon black, conductive particles such as graphite, etc. are listed. Examples of products include Toka Black manufactured by Tokai Carbon Co., Ltd. # 4500) may be kneaded into the resin material for antistatic treatment. This makes it difficult for the contaminants (dust) such as dust to adhere to the packaging easily, and as a result, the contaminants hardly adhere to the outer peripheral surface of the belt.

  In the belt packaging container 100 according to the present embodiment, for example, the belt 30 is first disposed in the second container body 20 while the belt movement restriction member 24 is inserted into the belt 30 in a state where the outer peripheral surfaces do not contact each other. To do. Then, the belt movement restricting member 14 is inserted into the belt 30 and overlapped so that the edge plate 13 of the first container body 10 and the edge plate 23 of the second container body 20 are in contact with each other. And the fixed string 40 is wound around a container, and a 1st container and a 2nd container are fixed. In this way, the belt 30 is packed by the first container body 10 and the second container body 20.

  For this reason, the belt 30 has one end surface and an inner peripheral surface on one end side in contact with the bottom outer wall of the belt movement restricting member 14 of the first container body 10, and the other end surface and the inner peripheral surface on the other end side. The second container main body 20 is abutted by the bottom outer wall of the belt movement restricting member 24 and packed in a stretched state, and its movement is restricted. And the belt 30 is packed without the outer peripheral surface contacting the 1st container main body 10 and the 2nd container main body 20 in this state.

  For example, as shown in FIG. 5, the belt packing container 100 according to the present embodiment is further packed in a packing box 42 and shipped in a state of being stored in a packing bag 41. Here, FIG. 5 is an exploded perspective view for explaining a method of packing the belt packaging container 100 according to the first embodiment.

  In the packaging container according to the present embodiment described above, the movement of the belt 30 is restricted by the belt movement restricting members 14 and 24 being brought into contact with the end face and / or the inner peripheral face of the belt 30, and the first container body 10 is restricted. And the belt whose outer peripheral surfaces are not in contact with each other by the second container body 20 is packed in contact with the outer peripheral surface. In this way, the belt 30 is packed with its outer peripheral surface not in contact with the member of the packaging container, and only its end surface and / or inner peripheral surface is in contact with the member of the packing container.

  For this reason, it is possible to prevent rubbing scratches and contact marks generated on the outer peripheral surface of the belt during the packing operation and transportation / storage process, and it is possible to prevent permanent distortion due to packing. Of course, damage to the belt 30 is also prevented.

  Further, since the belt movement restricting members 14 and 24 are arranged so as to stretch the belt 30 to be packed, the movement of the belt 30 in the packed state is substantially eliminated, and the packing work and the transportation / storage process are more effectively performed. In this case, it is possible to prevent rubbing scratches and contact marks generated on the outer peripheral surface of the belt and to prevent permanent distortion due to packaging.

  Moreover, since the packaging container is divided into the first container body 10 and the second container body 20 and the two members, the packaging work is facilitated and the opening is also facilitated.

  As shown in FIGS. 8 to 9, the belt packing container 300 according to the third embodiment is fitted with the belt 30 and a belt movement regulating member 50 that regulates the movement of the belt 30 by fitting the belt 30. The belt 30 fitted to the belt movement regulating member 50 is constituted by a cubic packing container main body 52 that packs the belt 30 on the outer peripheral surface thereof in a non-contact manner.

  The belt movement restricting member 50 includes a tubular restricting portion 50A that is fitted so as to come into contact with the inner wall of the belt 30, and a rectangular plate-shaped pedestal 50B. Further, a rectangular plate-like body having a columnar part 50D fitted so as to be in contact with the inner wall of the cylindrical regulating part 50A (the inner wall on the side opposite to the side where the plate-like base 50B is connected). 50C. The plate-like body 50 </ b> C is disposed by fitting the cylindrical portion 50 </ b> D to the cylindrical regulating portion 50 </ b> A in a state where the belt 30 is fitted.

  The belt movement regulating member 50 is packed so that the four sides of the rectangular plate-like pedestal 50 </ b> B and the plate-like body 50 </ b> C are in contact with the inner wall of the container main body 52.

  For this reason, the belt movement restriction member 50 is restricted from moving when the belt movement restriction member 50 is packed in the container main body 52. As a result, the belt 30 restricts movement of the belt 30 in the container main body 52, Contact between the outer peripheral surface of the belt 30 and the container main body 52 is prevented.

  Therefore, the belt packaging container 300 according to the present embodiment can prevent rubbing scratches and contact marks generated on the outer peripheral surface of the belt during the packing operation and the transportation / storage process, and can prevent permanent distortion due to packaging.

  In the belt packaging containers 100 to 300 according to each embodiment, the applied belt 30 has a surface property (surface roughness, contact angle, flatness, gloss, etc.) closely related to the image quality to be formed. A functional belt for an electrophotographic apparatus (for example, an intermediate transfer belt, a transfer conveyance belt, a fixing belt, or the like) that has a problem that an image defect is likely to occur when sliding scratches or dirt occurs in the transportation process is effective. However, the present invention is not limited to this, and the present invention can be effectively applied as long as the outer peripheral surface of the belt 30 has a rubbing scratch or a contact mark that deteriorates its characteristics.
