Title:
AUTOMATIC FEEDING DEVICE FOR LITHOGRAPHIC PRINTING PLATES
Document Type and Number:
WIPO Patent Application WO/2007/086580
Kind Code:
A1
Abstract:
An automatic feeding device for lithographic printing plates capable of reducing carrying resistance when lithographic printing plates are carried one by one by being separated from a bundle of slip-sheet-less lithographic printing plates using a roller-pick method, and being constructed simply and inexpensively using a low-output, small drive motor. With a bundle of slip-sheet-less lithographic printing plates (10) kept loaded, the upper-most lithographic printing plate (10) in the bundle is pulled up from lithographic printing plates (10) below using a handling operating unit (164, 1164), a carrying resistance reducing member (166) or a protection member (1166) is inserted between them by an input/output operating unit to put it ready for use, and a carrying out roller (146, 1146) is rolled within a range corresponding to the carrying resistance reducing member (166) or the protection member (1166) in the uppermost printing plate (10) to thereby carry out the uppermost printing plate (10) with a low carrying resistance. Alternatively, the uppermost lithographic printing plate (2010) housed in a printing plate supply cassette (2020) is sucked by vacuum-suction of a sucker (2202), and is handled at the portion thereof directly below where the sucker (2202) of a lithographic printing plate (2010) is tightly attached using a waveform suction surface of the sucker (2202) to thereby prompt air to flow to between the uppermost lithographic printing plate (2010) and lithographic printing plates (2010) below it.
