Abstract
A linear vibratory conveyor has a bottom plate and a vibratory conveyor track. Together with a trimming weight, the latter forms a vibrating mass. Further, a countermass is provided forming a mass vibrating in an opposite direction. The support of the masses, vibrating reciprocally, referred to the bottom plate takes place by way of spring elements formed by leaf springs. An electromagnetic vibratory drive fed by a cycled d-c potential engages between the masses vibrating reciprocally. A coupler of elastically damped action is provided between the masses vibrating reciprocally for the masses to vibrate exactly reciprocally one referred to the other even when out of resonance.
Claims8
A linear fibratory conveyor comprising:
- a bottom plate (32);
- a vibrating conveyor track (4);
- spring elements (2) disposed between the bottom plate (32) and the vibrating conveyor track (4);
- a trimming weight (8) linked to the vibrating conveyor track (4) and substantially determining a first vibrating mass (M1);
- a countermass (10) substantially determining a second vibrating mass (M2);
- spring elements (14) arranged between the bottom plate (32) and the countermass (10);
- a vibratory drive (15) formed by an electromagnetic drive engaging with the first vibrating mass (M1) on the one hand and with the second vibrating mass (M2) on the other hand;
- and
- a coupler (24) engaging between the first vibrating mass (M1) and the second vibrating mass (M2) and enforcing reciprocal vibration, wherein the coupler (24) has a coupler case (25) torsionally vibratable about a stationary axis (26) in relation to the bottom plate (32) and linked to the first vibrating mass (M1) and the second vibrating mass (M2) by way of a connecting rod (29, 30), and wherein the coupler (24) is separate from the vibratory drive (15).
