MACHINE FOR APPLICATION OF PATTERN THROUGH STENCIL Russian patent published in 1999 - IPC

FIELD: application of pattern on sealed flat items fed by a conveyer with a periodicity of 1/10 to 2 items per second. SUBSTANCE: the machine has a carriage mounted in the base. The carriage is installed on the stencil in guides parallel to it by means of bushes made of material whose metal friction coefficient does not exceed 0.004. The carriage drive uses a pneumatic actuator connected to the gas feed switch. The carriage guides are arranged in the same plane with the rod of the carriage pneumatic actuator in parallel with its axis. The mechanism of doctors alternate feed is installed on the carriage and consists of a rocker and doctors feed switch, which represents a double-acting air cylinder attached to the carriage and connected to its pneumatic actuator. The rocker is installed on the carriage for rocking in parallel with the direction of movement of the carriage and stencil. Attached to one end of the rocker are the levelling and decorating doctors, and the other end of the rocker is connected to the doctors feed switch. EFFECT: enhanced reliability of machine operation and precision of pattern application. 2 dwg
