摘要:
Vibration device (10) for a conveyor apparatus which is able to convey a metal charge towards a container of a melting plant and which comprises at least an oblong bearing structure (20) having a conveyor channel (21) and supported by supporting elements which allow it to oscillate, or vibrate, at least in a longitudinal direction (X). The vibration device (10) is fixed to the bearing structure (20) and comprises at least a first pair of eccentric masses (35a, 36a) mounted off-axis on two corresponding bearing shafts (40, 41) able to rotate in synchrony with each other in order to feed in this way the metal charge on the conveyor channel (21) towards the container. A first eccentric mass (35a) is angularly out- of-phase by an angle (phi) other than zero, with respect to the second eccentric mass (36a) of the same pair of eccentric masses (35a, 36a).

The linear vibratory feeder (10) has a base (12), an overlying track support plate (30) and a counterweight (82) with an internal structure between the base (12) and support plate (30) and a pair of outer side plates (70) secured to each of a plurality of separate, longitudinally spaced parts of the internal structure. A first pair of vertical, relatively flexible, flat leaf springs (20) extend between the base (12) and internal structure and a second pair of generally upright but slightly inclined, flat leaf springs (40) extend between the internal structure and support plate (30). The first and second pairs of leaf springs (20, 40) are mounted in overlapping relationship to provide a low profile feeder and a short moment arm between the centers of gravity of the upper support plate assembly (30) and counterweight (82).
摘要:
The invention relates to a drive system for conveyor systems comprising an motor and a transmission. One or more clutches can be provided between the motor and transmission. The drive system can be mounted by means of a torque support. In order to reduce vibrations of the drive system, a damper is arranged on the axial motor-side end. If the motor, the transmission and, optionally, other components of the drive system are mounted on a rocker, the damper can be arranged on the motor-side axial end of the damper.

A two mass vibratory apparatus (10,50) for processing work material includes a bed (12,58) defining a transport surface for receiving the objects, an elastic amplifier (24,56) having a first end connected to the bed (12,58) and a second end, and a base (26,52) connected to the elastic amplifier (24,56) second end. A linear actuator (28,60) is mounted on the base (26,52) and adapted to generate a linear vibratory force that is amplified by the elastic amplifier (24,56) thereby to move the bed (12,58) in a vibratory motion, so that the work material moves in response to the vibratory motion of the bed (12,58).

A three mass vibratory apparatus for processing work material includes a bed defining a transport surface for receiving the objects, an elastic amplifier having a first end connected to the bed and a second end, and a drive base connected to the elastic amplifier second end. A linear actuator is mounted on the drive base and adapted to generate a linear vibratory force that is amplified by the elastic amplifier thereby to move the bed in a vibratory motion, so that the work material moves in response to the vibratory motion of the bed. The bed defines a first mass, the drive base and linear actuator define a second mass, and the reciprocating weight defines a third mass, the first, second, and third masses being isolated from rigid coupling to one another
摘要:
A differential impulse conveyor (10) includes a tray (12) laterally moveable in a forward direction at a first speed and in a backward direction at a second speed greater than the first speed, thereby moving goods along the tray. A plurality of legs (18, 20) support the tray during lateral movement, and a motor (30) powers a drive pulley (30). A driven pulley (36) is powered by the drive pulley, and a flexible member (34) interconnects the driven pulley and the drive pulley. At least the driven pulley has an eccentric pulley axis, thereby imparting lateral movement to the tray. A tension mechanism (38, 40) is provided to take up slack in the flexible member.
摘要:
Vibration device for a conveying apparatus (21) to convey a metal charge in a longitudinal direction (X) comprising at least two vibration mechanisms (25, 26) each disposed on opposite sides of the conveying apparatus (21) so as to feed the metal charge. The vibration mechanisms (25, 26) comprise at least a first plurality of eccentric masses (31, 32, 33) having their mass barycenters (B) oriented in parallel directions to each other, and a second plurality of eccentric masses (34, 35) having their mass barycenters (B) disposed angularly offset with respect to the disposition of the barycenters of the first plurality of eccentric masses (31, 32, 33).
