Abstract

A differential impulse conveyor system including detectable markers disposed in a series on a moving component of the conveyor system. A stationary sensor disposed in close proximity to the markers generates a signal when the moving component is in a first range of motion to dispose the markers proximal to the sensor, and the sensor either fails to generate a signal when the moving component is not within the first range of motion. The sensor signal causes a current conditioning device to condition current from a current source to operate a motor to power the conveyor tray at a first rate of acceleration in a first mode, and the lack of the signal causes the current conditioning device to operate the motor to power the conveyor tray at a second rate of acceleration in a second mode. Markers may be positionable to optimize the timing of the current modes.

Dependent claims

A differential impulse conveyor, comprising:

an elongate conveyor tray movable in a forward direction at a first rate of acceleration and in a backward direction, opposite to the forward direction, at a second rate of acceleration that is greater than the first rate of acceleration, thereby moving goods along the tray in the forward direction, the tray having a first end, a second end, a trough therein for conveying goods, and a conveyor drive coupling;
a counterweight assembly having a first side, a second side, a trough therebetween to receive at least a portion of the conveyor tray, and a counterweight drive coupling;
an electrically powered motor having a rotating output shaft;
a first rotary to linear reciprocating motion converter coupled intermediate the rotating output shaft of the motor and the conveyor drive coupling;
and
a second rotary to linear reciprocating motion converter coupled intermediate the rotating output shaft of the motor and the counterweight drive coupling;
wherein operation of the motor causes the conveyor tray to move in the forward direction and the counterweight assembly to simultaneously move in the backward direction;
and
wherein continuing operation of the motor causes the conveyor tray to reverse direction and to move in the backward direction and the counterweight assembly to simultaneously move in the forward direction.

A differential impulse conveyor, comprising:

an elongate conveyor tray movable in a forward direction at a first rate of acceleration and in a backward direction, opposite to the forward direction, at a second rate of acceleration that is greater than the first rate of acceleration, thereby cyclically moving goods along the tray in the forward direction, the tray having a first end, a second end, a trough therein for conveying goods, and a conveyor drive coupling;
an electrically powered motor having a rotating output shaft;
a first rotary to linear reciprocating motion converter coupled intermediate the rotating output shaft of the motor and the conveyor drive coupling;
and
a plurality of markers secured to a moving component of the differential impulse conveyor;
and
a sensor disposed proximal to the moving component sensing movement of the plurality of markers;
and
wherein operation of the motor causes the conveyor tray to move in the forward direction;
and
wherein continuing operation of the motor causes the conveyor tray to reverse direction and to move in the backward direction.
