Abstract
A vibrator conveyor system, for example in the form of a circular or linear conveyor, has a reciprocating plate adapted for carrying a container, and electromagnetic oscillating armature motors for moving said plate along a primary advancement direction or vector; each motor has a stationary stator, an armature secured to the reciprocating plate, and an excitation coil driven by alternating current or pulsating direct current, the coil being disposed on a pole piece the stator, the pile piece having a stator pole surface cooperating with an armature pole surface. The reciprocating plate is elastically supported by spring elements in a manner limiting its vertical and horizontal motion. The elongated spring elements are aligned along at least a portion of the rim of the plate with equal inclination with respect to a plane containing the conveyor advancement vector, and are fastened to the plate. The armature and stator of at least two oscillating armature motors are each laminated of dynamo lamellae into a laminated packet and are disposed in the space enclosed by the spring elements with stator pole surfaces disposed in parallel planes.
