Abstract

A sheet takeout mechanism (10) has a takeout roller (2) that rotates in contact with a sheet located at a takeout position, and a motor (5) that intermittently rotates the takeout roller (2). A triangular suction port (3) is formed on a suction surface (2a) of the takeout roller (2) and has a vertex located downstream in a rotation direction (R) of the takeout roller (2). When a negative pressure is exerted on the sheet via the suction port (3), the suction force is weak at the beginning of suction and then increases gradually.

Description

technical field [0001] The present invention relates to a sheet take-out device that sucks and contacts a sheet placed at a take-out position, and then rotates to take out the sheet in a surface direction. Background technique [0002] Sheet material take-off devices are conventionally known which apply negative pressure to one of many sheets at the take-off position through a belt hole in an endless take-off belt to suck and contact the sheet , and then the take-out belt is intermittently advanced in the take-out direction to take out the sheet onto the conveyance path (for example, see Japanese Patent Application Laid-Open Publication No. 3735565). [0003] In addition to the extraction chamber, the device has a negative pressure chamber across the extraction belt opposite the extraction location and a chamber mask located between the negative pressure chamber and the extraction belt. Two masking holes are formed in the chamber mask, the two masking holes being separated ...
