Description

  The present invention relates to a packaging method for transporting photographic film material, and in particular, maintains the packaging state without overloading the photographic film material being transported, and the quality of the product and the workability of the manufacturing work performed after unpacking. It is related with the packaging method at the time of transportation which suppressed movement of the photographic film material which improves.

  In the production of photographic film, production of the photosensitive material, film-based casting, photosensitive material application, and processing of other film components require large-scale equipment and high technical level, so they are produced at one location. The roll-shaped roll film (the film in this state, hereinafter also referred to as pancake film) of the final product width produced is transported to another place where the pancake film is transferred to a predetermined length. In many cases, the product is cut into pieces, loaded into a cartridge, and then capped to produce a final film product.

  However, when transporting photographic film material from a coating factory to a secondary processing factory, physical damage to the photographic film material caused by vibrations and shocks during transportation may cause the photographic film material to be used in the secondary processing factory. Various problems have occurred.

  That is, in a roll-shaped film in which the film is slit to the final product width, winding looseness occurs due to vibrations / impacts during transportation and changes in temperature and humidity, and as a result, when the film is loaded into the processing device, the roll shape It is a problem that the film is displaced in the shape of a bamboo shoot, or the winding breaks and falls apart.

  In addition, in the cartridge caps that are component parts of the cartridges that are processed by press processing, the cartridge caps rub against each other during transportation, and the coating surface of other cartridge caps that rub against the burrs during the press processing of the cartridge caps may be damaged. There are also problems such as the paint peeling that occurs adheres to the film and causes troubles in the photographed image, and the appearance of the paint cap peels off and rusting occurs.

  As a packaging method for transporting photographic film materials such as roll-shaped films and cartridge caps, it is common to store the photographic film material in a cardboard box, which is a packaging container, and fix the photographic film material with a cushioning material. As a buffer material that fills the gap between the packaging container and the photographic film material, a general-purpose chip-shaped or spherical foamed polystyrene or a sheet material made of a synthetic resin having a large number of air layers, etc. It was used. However, such a packaging method at the time of transportation cannot be said to be an effective method for problems such as loose winding of a roll film and rubbing between cartridge caps.

Further, as an alternative to a general-purpose cushioning material that fills the gap of the packing container, a cushioning material composed of a rubber member that allows gas to enter and exit is proposed (for example, Patent Document 1). However, this cushioning material is also expensive, and there is a problem that a device is required when gas is injected into the inside. Moreover, even if this buffer material is used, it can be inferred that it is difficult to prevent the rolled film wound in a roll shape from being loosened and rubbing the coated steel plate parts such as the cartridge cap. That is, the loose winding of the roll-shaped film occurs when vibrations and impacts during transportation are repeatedly applied in the direction of the roll diameter, and the cushioning material composed of the rubber member of Patent Document 1 is in a direction perpendicular to the roll diameter. However, it is considered that the effect is small in the direction of the roll diameter. In addition, as a packaging method for transporting coated steel plate parts such as cartridge caps, it is a common practice to put the coated steel plate parts in a small bag and then put them in a cardboard box and put cushioning materials. If a bag with high airtightness is used, an air layer (space) is created inside the bag due to vibration and impact during transportation, and even if the cushioning material of the rubber member of Patent Document 1 is used, the pressing force does not work sufficiently, and the bag interior It is thought that the coated steel plate parts will be easy to move. Further, in the rubber member of Patent Document 1, when the gap between the small-sized bag and the cardboard box becomes small, the rubber member cannot enter the gap, and there is a risk that an air layer (space) inside the bag is formed.
Japanese Patent Laid-Open No. 7-251867

  In order to prevent the roll film from loosening, it must withstand vibrations and shocks that are repeatedly applied in the direction of the roll diameter. To that end, a pressing force is applied from the outer circumference to the center of the roll diameter. It is effective.

  In addition, to prevent rubbing of coated steel plate parts such as cartridge caps, the air inside the bag should be reduced during packing, or the air inside the bag should be excluded when cushioning material is inserted. Is effective.

  In order to solve the above problems, the present invention provides an inexpensive and simple packaging method for transporting photographic film materials that can prevent rolling film from loosening and prevent rubbing of coated steel plate parts such as cartridge caps. The purpose is to provide.

The object of the present invention can be achieved by the following constitution.
