Title:
SHEET EJECTION DEVICE AND SHEET EJECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2013/018849
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a sheet ejection device enabled to operate continuously by automatically disabling an intrusion detector while effectively ensuring safety and also provide a sheet ejection method. The sheet ejection device comprises: a paper ejection chain (22b) for conveying paper (W); a first pile (26) or a second pile (26b) having loading plates (27a or 27b) arranged in a multistage manner and used for loading the paper ejected from the paper ejection chain; a first beam sensor (62a or 62b), a second beam sensor (63a or 63b), and a third beam sensor (64a or 64b) for detecting an intrusion into the first pile or the second pile. The sheet ejection device further comprises: a plate upper-limit position detection sensor (58a or 58b) for detecting that the loading plate has been positioned at a plate upper-limit position (L2); and a control device (50) for, based on the detection signal of the plate upper-limit position detection sensor, neglecting (disabling) a command for stopping a driving device (printing machine), the command is issued by the first to third beam sensors.
