[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lithographic printing plate packing method for packing a bundle of lithographic printing plates so that they can be transported without collapse.

[0002]

2. Description of the Related Art In a lithographic printing plate manufacturing line such as a photosensitive printing plate or a heat-sensitive printing plate, a lithographic printing plate comprising a predetermined number of lithographic printing plates in a main form according to the size and type of the lithographic printing plate. The bundle of printing plates is packed so that the bundle of planographic printing plates can be transported. Particularly, as a packing structure suitable for packing a large number of planographic printing plates, for example, JP-A-3-73946,
No. 000-118533.

FIG. 7 shows a planographic printing plate packaging structure described in Japanese Patent Application Laid-Open No. 3-73946. In this packing structure 210, a bundle 218 of a predetermined number of lithographic printing plates 216 is placed on a back plate 214 which is erected with respect to a bottom plate 212 with casters.
0 is applied to the front side of the bundle 218, and then the back plate 214 and the contact plate 220 are fastened with bolts 222 to fix the bundle 218 of the lithographic printing plate 216. Thereby, the packing of the bundle 218 of the lithographic printing plates 216 in the vertically stacked state is completed, and the lithographic printing plates 2 are placed between the back plate 214 and the plate 220.
16 and the lithographic printing plate 21
The movement of the bundle 218 with respect to the bottom plate 112 is prevented.

In the method of packing a lithographic printing plate (packing method) described in Japanese Patent Application Laid-Open No. 2000-118533, a bundle of lithographic printing plates is stacked in a flat state on a pallet made of corrugated cardboard, and the lithographic printing plate is loaded. The bundle of printing plates is wrapped with light-shielding and moisture-proof interior paper, and after covering the outside of the interior paper with an exterior material such as cardboard, a band is wound around the exterior material and the band is used to form a lithographic printing plate. The bundle is bound on a pallet. This completes the packing of the bundle of planographic printing plates in the flat stacked state, restricts relative movement between the planographic printing plates constituting the bundle of planographic printing plates, and moves the bundle of planographic printing plates with respect to the pallet.

[0005]

However, the packaging is completely completed by the lithographic printing plate packaging structure disclosed in Japanese Patent Application Laid-Open No. 3-73946 and the lithographic printing plate packaging method disclosed in Japanese Patent Application Laid-Open No. 2000-118533. Until the above, the movement of a large number of planographic printing plates constituting a bundle of planographic printing plates cannot be restricted, and the occurrence of deviation between planographic printing plates cannot be effectively prevented. Therefore, the following problem occurs. For example, in a lithographic printing plate production line, lithographic printing plates dropped from a belt conveyor are accumulated by an accumulation device arranged at the end of the line. At this time, the stacking device forms a bundle of the lithographic printing plates by stacking the lithographic printing plates on the loading member. Usually, the bundle of lithographic printing plates is transported together with the loading member from the stacking device to the packaging / packing process. May occur.

In the packing structure disclosed in JP-A-3-73946, the lithographic printing plates constituting the bundle of lithographic printing plates are not directly restrained, and when a large impact is applied during transportation, the lithographic printing plates are liable to be damaged. There is a possibility that a deviation occurs between the planographic printing plates constituting the bundle of printing plates. On the other hand, JP-A-2000-1185
In the case of the packing method disclosed in Japanese Patent Publication No. 33, it is necessary to wind a band from the outside of these packaging materials while keeping the packaging materials in close contact with the top and side surfaces of the bundle of planographic printing plates. For this reason, the packaging operation becomes complicated and a large amount of packaging material such as cardboard is required.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for packaging a lithographic printing plate that can effectively prevent the occurrence of misalignment between the lithographic printing plates in a bundle of lithographic printing plates and suppress the amount of packaging material used. It is to provide a method.

[0008]

According to the method of packing a lithographic printing plate of the present invention, a band-shaped binding member is wound around the outer surface of a bundle on a stacking member to restrain relative movement between the lithographic printing plates. After binding the bundle of planographic printing plates to the stacking member by the binding member, the bundle of planographic printing plates bound to the stacking member is stacked on a carrier member for transportation, thereby forming a bundle of planographic printing plates. The lithographic printing plate can be directly restrained by the binding member and the lithographic printing plate bundle can be directly bound and fixed to the loading member, so that an external impact acts during transportation or the lithographic printing plate bundle tilts. Even in this case, it is possible to effectively prevent displacement between planographic printing plates and displacement of the bundle of planographic printing plates with respect to the stacking member.

Further, since the bundle of planographic printing plates on the stacking member is stacked on the carrier member while being bound by the binding member, the bundle of planographic printing plates can be packaged on a carrier member such as a pallet by using an exterior material or a band. Even if wrapping and bundling are omitted using such as, there is no shift between planographic printing plates, and it is possible to simplify packaging (exterior) and packaging materials and operations related to packaging.

Further, in the method for packing a lithographic printing plate of the present invention,
If a predetermined number of planographic printing plates are stacked on a stacking member to form a bundle of planographic printing plates, the bundle of the planographic printing plate bundle and the binding member to the stacking member can be bound without packaging with an exterior material or the like. Since it is possible, immediately after the lithographic printing plate bundle is formed on the stacking member, the bundled work of the lithographic printing plate bundle and the stacking member is carried out at the accumulation position in the production line without transporting them to the packaging / packing process. Can be easily performed. If the bundle of the lithographic printing plates and the bundling of the stacking members are performed at the stacking position in this way, a deviation occurs between the lithographic printing plates due to vibrations and the like when transported from the stacking position to the packaging / packaging process. Can be prevented.
