Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing plate transporting method, and more particularly to a printing plate transporting method for transporting a printing plate from a warehouse to a printing plate printing apparatus by an unmanned transporting carriage.

[0002]

2. Description of the Related Art Generally, a printing plate has a photosensitive resin formed on a support such as an aluminum plate. This photosensitive printing plate is usually as large as about 1 m × 1 m, and its weight is 500 to 1000 g per plate, which is quite heavy, and there are many types in general. Furthermore, the plate thickness is as thin as 0.1 to 0.5 mm. Therefore, there is a risk in handling the printing plate, which is a heavy labor and is more complicated to handle.

Conventionally, a printing plate has been manually transported from a warehouse to a predetermined printing plate printing apparatus by a mounting carriage. Also,
The printing plates were loaded and unloaded using a transport tool such as a jack.

However, the handling of printing plates by hand has the following problems.

(1) Since the printing plate is as heavy as about 500 to 1000 g and has a large size of about 1 m × 1 m, it is easy to be injured during transportation, loading, unloading, etc., and there is a safety problem.

(2) Further, since the printing plate is heavy and large as described above, it requires heavy labor.

(3) Further, there are various types of printing plates, such as differences in size, thickness, and photosensitivity, so that human error in management is likely to occur and management is complicated.

[0008]

A method of transporting a printing plate, which is characterized by transporting, (2) in (1), after transporting the printing plate to a predetermined printing plate printing apparatus or the like with the unmanned transport carriage, the printing plate mounting table A method of transporting a printing plate, which is characterized in that it is automatically mounted on a printing plate printing apparatus by an unmanned transporting vehicle, and (3) the unmanned transporting vehicle has a vertical drive mechanism for raising or lowering the printing plate placing table. Characterized by
The method of transporting a printing plate according to item (1) or (2).

Here, the "unmanned transporting cart" is a transporting device for freely transporting a printing plate between a warehouse and one or more printing plate printing devices laid out. For example, it is operated by electromagnetic induction from a guide wire provided on the floor.

The "warehouse" means a printing plate in which printing plates are stacked, or a place where the printing plates are temporarily stored in a state of being placed on a printing plate mounting table.

[0012]

The operation configured as above will be described. According to the first aspect, the printing plate mounting table on which the printing plate is mounted is taken out from the printing plate warehouse. After that, the printing plate placing table is loaded on the unmanned transport vehicle. This unmanned carrier is used to carry the product from the warehouse to a designated printing plate printing apparatus or the like. afterwards,
Lower the printing plate placement table and attach it to the printing plate printing device.

Further, in claim 2, the printing plate placing table on which the printing plate is placed is taken out from the printing plate warehouse. After that, the printing plate placing table is loaded on the unmanned transport vehicle. This unmanned carrier is used to carry the product from the warehouse to a designated printing plate printing apparatus or the like. After that, the printing plate placing table is automatically attached to the printing plate printing apparatus or the like.

Further, in the third aspect of the present invention, in the operations of the first and second aspects, the mechanism for moving up and down the unmanned transporting vehicle is used to load and unload the printing plate mounting table. To do.
