PRODUCTION FLOW LINE FOR WORKING OF SWITCH TIES Russian patent published in 2007 - IPC B27M3/14 B27M1/04 

FIELD: wood-working industry, in particular, equipment for preimpregnation treatment of switch ties.

SUBSTANCE: the flow line for working of switch ties has a feeder, accumulator, turner, longitudinal and lateral conveyers, finished products receptacle, pricking and cracking preventing units, each having a feeding mechanism. The accumulator is installed between the units, each unit is provided with a feed control device having a beam pusher, rod made in the form of an incompletely turning shaft kinematically linked with the beam pusher and carrying a feeler mechanism that has a cylindrical surface separated into longitudinal sectors in compliance with the standard sizes of the beams, and cavities and a lug located in accordance with the plan of working of each standard size of the respective beam are made on the working surface of each sector, and a carriage with a lever switch installed for engagement with the front end of the beam, feeler mechanism and the feeding mechanism. As a modification of the invention is a feed control device having a master controller with a set of feed programs in accordance with the plans of working of all the standard sizes of the beams, and the rod is made in the form of a fixed rack carrying the feeler mechanism with the horizontal working surface with cavities made on it and positioned in accordance with the plans of working of beams of all the standard sizes, the beam pusher is provided with a program selector switch coupled to the carriage via the master controller.

EFFECT: produced a flow line for working of the switch tie beams supplied by sets, and providing a high-efficiency operation of the preimpregnation working of beams with automatization of the processes of determination of the beam standard size, adjustment of feeds and monitoring of the feed value for beams of each standard size.
