Abstract
A lift assembly for use in conjunction with a conveyor to lift item(s) off of the conveyor and remove the item(s) from the conveying path. The lift assembly may include a housing having housing side walls and a bottom wall, and a carriage having carriage side walls and a carriage bottom wall. The carriage is movable with respect to the housing. The lift assembly may further include a track that receives a guide member of the carriage for guiding the carriage as it is raised and lowered with respect to the housing. The lift assembly may further include an actuator that causes the carriage to be raised and lowered.
Claims18
A lift assembly for use with a conveyor configured to move items in a direction of conveyance, comprising:
- a housing comprising a pair of side walls positioned on either side of a conveying path and a bottom wall that is positioned below the conveying path;
- a carriage for engaging an item on the conveyor, wherein the carriage comprises a pair of carriage side walls on either side of the conveying path;
- a carriage bottom wall positioned between the bottom wall of the housing and the conveying path;
- and a pair of supports, each support supported by a respective carriage side wall and extending inwardly toward the conveying path;
- a track attached to the housing, the track being angled relative to the direction of conveyance and configured to support the carriage as the carriage moves relative to the housing;
- a guide member received within and movable along the track and operably attached to the carriage;
- an actuator attached at a first end to the carriage and at a second end to the housing for moving the guide member along the track;
- wherein the angle of the track is configured such that, as the guide member moves along the track, the carriage is raised and lowered with respect to the housing.
A lift assembly for use with a conveyor configured to move items along a conveying path in a direction of conveyance, comprising:
- a housing having two side walls located one on either side of the conveying path and a bottom wall between the two side walls;
- a carriage for engaging an item on the conveyor, the carriage being supported by the housing and comprising:
- two carriage side walls located one on either side of the conveying path,
- a carriage bottom wall,
- a pair of supports, each support being supported by a respective carriage side wall and extending inwardly toward the conveying path, and
- a pair of guide members, each guide member being supported by a respective carriage side wall;
- a pair of tracks that guide the carriage as it is raised and lowered with respect to the housing, each track receiving a respective guide member and being angled relative to the direction of conveyance so as to support the carriage as it is raised and lowered;
- and
- an actuator configured to move the carriage along the tracks for raising and lowering the carriage with respect to the housing.
A lift assembly for use with a conveyor configured to move items along a conveying path in a direction of conveyance, comprising:
- a housing having two side walls located one on either side of the conveying path and a bottom wall below the conveying path;
- a carriage for engaging an item on the conveyor, the carriage being supported by the housing and comprising:
- two carriage side walls located one on either side of the conveying path,
- a carriage bottom wall,
- a pair of supports, each support being supported by a respective carnage side wall and extending inwardly toward the conveying path, and
- a pair of guide members, each guide member being supported by a respective carriage side wall;
- a pair of angled tracks that guide and support the carriage with respect to the housing, wherein the tracks are angled relative to the direction of conveyance, and each track receiving a respective guide member;
- and
- an actuator configured to move the carriage along the angled tracks for raising and lowering the carriage with respect to the housing, one end of the actuator being attached to the housing and the opposite end of the actuator being attached to the carriage, wherein the actuator is situated between the side walls of the housing.
