FIELD: automatic and semiautomatic newspaper vending machines. ^ SUBSTANCE: in proposed device containing drive and fixed support for pile of sheet articles, gripper of putout mechanism thrust against upper sheet of pile at initial force required for putting out most thin sheet article and it is made in form of flexible material roller of high friction coefficient on paper being installed on carriage hinge-connected over and behind the roller with positioning holder provided with stop and support spring keeping part of carriage with roller in contact with stop and provided with possibility of lowering, without changing angle of tilting, as height of pile decreases, and fixing by reverse travel stop. Thanks to it roller, moving along fixed sheet backwards from side of putting out and tilting the carriage downwards and extending the support spring, increases automatically force of pressing and separation to value required for separation and putting out copy of sheet article without creating forces for gripping two or more articles. Positioning holder can be released from locking to lift carriage with roller to put in new pile. Initial roller pressing force is provided by counterweight of putout mechanism. ^ EFFECT: enlarged nomenclature of handled sheet articles, improved reliability. ^ 10 cl, 2 dwg |
