GLUE DEVICE IN BOOKBINDING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a glue device which maintains a simple structure to contact/separate a wiper to/from a glue drum by its cam mechanism and in which the separation amount between the wiper and the surface of the glue drum is easily adjusted. SOLUTION: The glue device in a bookbinding machine includes: the glue drum 5 which picks up glue in a glue container 3 and rotates; the wiper 6 fixed to a turning shaft 9; and a cam 11 which turns around the turning shaft 9. Turning of the turning shaft 9 due to the turning of the cam 11 contacts/separates the wiper 6 to/from the surface of the glue drum 5 for a certain period of time so that the glue attached on the surface of the glue drum 5 when separating is applied to the back surface of a book body moving above the glue drum 5. An arm 23 is fixed on one end of the turning shaft 9, and a position-changeable stopper 25 is provided which contacts the arm 23 to stop the turning of the turning shaft 9. The stopper 25 is positioned at a set value previously set in memory according to the thickness of the glue to be applied to the book body. COPYRIGHT: (C)2011,JPO&INPIT
