Claims (1)

[Claims for Utility Model Registration] (1) Lift-down systems, advance return systems, and clamp-unclamp systems in which a pair of horizontal and parallel feed bars are moved up and down, moved forward and backward in the longitudinal direction, and moved toward and away from each other. In a mechanical transfer feeder having a mechanism, one
The lift-down system and the advance return system each include a cam provided on the camshaft, a cam lever pivotally supported on the feeder box, and a cam lever pivoted on the feeder box by rotation of the camshaft. a cam device that operates the feed bar in one direction via an operating member connected to a tip; a cam device having a base pivotally connected to the feeder box and a tip pivotally attached to the cam lever and operating the feed bar in a reverse direction via the operating member; The clamp/unclamp system has a cylinder device that causes the clamp/unclamp system to operate by rotating the camshaft through a pair of cams provided on the camshaft, a pair of cam levers pivotally supported by the feeder box, and a pair of actuating members. a cam device that moves the feed bar in one direction; and a pair of cylinder devices that have a base pivotally connected to the feeder box and a tip that is pivotally connected to the pair of cam levers to move the feed bar in the opposite direction via the pair of operating members. The operating member of the lift-down system is separated into horizontal and vertical members so as to be slidable in the clamping and unclamping directions, and the feed bar is connected to the sliding side member, and the clamping・The operating member of the unclamp system is horizontal,
Hold and clamp the sliding side member of the vertical member,
It is movable in the unclamping direction, and the operating members of the advance return system are clamps,
A single cam type mechanical transfer feeder, characterized in that it is connected between the feed bar and the cam lever of the advance return system so as to be swingable in an unclamping direction. (2) The cam device is arranged to cause the feed bar to perform unclamp, lift-up, and return operations in one direction, and the cylinder device is arranged to cause the feed bar to perform clamp, lift-down, and advance operations. The single-cam type mechanical transfer feeder according to claim 1, wherein the single-cam type mechanical transfer feeder is arranged.
