As is clear from the above description, the plate feeding apparatus of the present invention can exhibit the following excellent effects. (1) A common dark room is provided for unpacking the plate material packed in a different location from the plate making device, and the unexposed plate material unpacked in the dark room is transferred to the top of the plate making device using a dark box and a transport vehicle. As compared with a conventional plate-making device in which the dark room, which constitutes a part of the plate-feeding device, is docked at the most upstream side of the plate-making device, it is carried into the plate material supply device installed on the side of the plate-making device. Significant miniaturization can be achieved. As a result, the installation space is small, and the installation location is not restricted. (2) Since a shutter device is provided between the exposure device and the plate material supply device to block light from entering and exiting the shutter device, the exposure device is operated by operating the shutter device. A new unexposed plate material can be put into the plate material supply device. Of course, when a trouble occurs in the exposure equipment and the inspection
Even if unexposed plate material remains in the plate material supply device,
It is possible to inspect the exposure device without exposing the unexposed plate material to light and without exposing the plate material in the plate material supply device. (3) A lining material is placed on the outer peripheral edge of the main body of the dark box so that the space between the main body and the lid can be sealed. Exposure of an unexposed plate material can be reliably prevented. (4) A dark box is provided with guide and positioning rails.
A plurality of guide rollers that guide the rails of the dark box and support the dark box so that they can move horizontally are provided on the side of the transport vehicle and the plate material supply device. It is possible to easily and easily take out the dark box from the material supply device onto the transport vehicle. (5) Since the lock mechanism for fixing the dark box on the transport vehicle is provided between the dark box and the transport vehicle, the dark box escapes on the transport vehicle and falls from the transport vehicle during transport of the dark box. Can be prevented and is excellent in safety. (6) A cover opening / closing device in which the plate material supply device opens and closes the cover of the dark box, and a slip sheet take-out device that takes out the plate surface protection slip sheet between the plate materials in the dark box to the outside of the dark box. Since it is provided, removal of the slip sheet and opening and closing of the lid can be automated, and the processing capacity can be improved. (7) Since the shutter device is a roll-winding shutter device, it is possible to reliably shield light between the plate material supply device and the exposure device with a simple structure, and to reduce the installation space. (8) Since a two-stage telescopic rail is used for the plate material transport device, and a head unit for adsorbing and holding the plate material is provided on this rail, the stroke of the telescopic rail becomes long and the moving distance of the head unit is reduced. I can take it for a long time. As a result, there is no need to dispose the plate material transport device over the plate material supply device and the exposure device, and it is possible to dispose the plate material transport device on the exposure device side. In the end,
When disposing the shutter device between the plate material supply device and the exposure device, the plate material transport device does not interfere. (9) Since the head unit has a plurality of suction plates, and the suction plates for sucking both ends of the plate material in the dark box are moved up and down with respect to the head unit, the suction plates hold the plate material by suction. When the plate material is lifted, the interleaf sandwiched between the plate materials does not adhere to the back surface of the plate material and is lifted, so that only the plate material can be reliably transported to the exposure device side.
