Apparatus for loading articles into lanes on horizontal shelves

Claim 2

Apparatus for loading articles into lanes on horizontal shelves comprising a loading frame mounted on wheels to permit the frame to move horizontally in a first direction, a main carriage supported by said frame for vertical movement, an auxiliary carriage supported by said main carriage for horizontal movement relative thereto in a second direction between operative and inoperative positions, said second direction being perpendicular to said first direction, a horizontal plate member supported by said auxiliary carriage and adapted to bridge a gap between said auxiliary carriage and a shelf in the operative position of the auxiliary carriage, a lane actuator supported by said auxiliary carriage and being adapted to drive an endless member connected to a pusher in a shelf lane to a reloading position, motor means on said auxiliary carriage for driving said lane actuator, whereby articles may be reloaded onto a shelf lane from said plate member when said auxiliary carriage is in its operative position.

Claim 3

Apparatus in accordance with claim 1 wherein said lane actuator includes a sprocket supported by one end of a pivotable lever, and a shock absorber coupling said lever to said auxiliary carriage.

Claim 4

Apparatus in accordance with claim 1 wherein said loading frame has a first set of wheels at the upper end thereof for rotation about a horizontal axis and a second set of wheels at the lower end thereof for rotation about a vertical axis, the wheels at the upper end of the loading frame being support wheels, the wheels at the lower end of the loading frame being guide wheels.

Claim 5

Apparatus in accordance with claim 1 wherein said loading frame includes a pair of vertically disposed guide shafts, said carriages being between said guide tubes, a pair of C-shaped bearings on opposite sides of said main carriage, each bearing embracing one of said shafts.

Claim 6

Apparatus in accordance with claim 1 including a movable means mounted on said main carriage for causing said auxiliary carriage to move in said second direction.

Claim 7

Apparatus for loading articles into lanes on horizontal shelves comprising a loading frame, a main carriage supported by said frame for vertical movement, an auxiliary carriage supported by said main carriage for horizontal movement relative to the main carriage, means extending between said carriages to cause movement of the auxiliary carriage from an inoperative position to an operative position, means at least partially connected to the main carriage for retracting the auxiliary carriage to an inoperative position, a horizontally disposed plate member on said auxiliary carriage for supporting articles to be transferred onto a shelf, a lane actuator supported by the auxiliary carriage, motor means on one of said carriages for driving said lane actuator, and said lane actuator being adapted to cooperate with structure on a shelf for retracting a lane pusher to a reloading position.

Claim 8

Apparatus for loading articles into lanes on horizontal shelves comprising a loading frame, a main carriage supported by said frame for vertical movement, an auxiliary carriage supported by said main carriage for horizontal movement relative to the main carriage, means extending between said carriages to cause movement of the auxiliary carriage from an inoperative position to an operative position, means at least partially connected to the main carriage for retracting the auxiliary carriage to an inoperative position, a horizontally disposed plate member on said auxiliary carriage for supporting articles to be transferred onto a shelf, a lane actuator supported by the auxiliary carriage, motor means on one of said carriages for driving said lane actuator, and said lane actuator being adapted to cooperate with structure on a shelf for retracting a lane pusher to a reloading position.

Claim 9

Apparatus in accordance with claim 6 including support wheels at the upper end of said frame and guide wheels at the lower end of said frame to facilitate horizontal movement of the frame in a direction perpendicular to the horizontal direction of movement of the auxiliary frame.

Claim 10

Apparatus in accordance with claim 6 wherein said lane actuator is a sprocket, a guard on said auxiliary carriage for preventing contact between said sprocket and articles to be transferred from the plate member to a shelf.

Claim 11

Apparatus in accordance with claim 6 wherein said auxiliary carriage is spring biased to its operative position, and said means extending between the carriages being a handle pivoted to said main carriage for cooperation with an actuator depending from said auxiliary carriage.

Claim 12

Apparatus for loading articles into lanes on horizontal shelves comprising a loading frame, a main carriage supported by said frame for vertical movement, an auxiliary carriage supported by said main carriage for horizontal movement relative to the main carriage, support wheels at the upper end of said frame and guide wheels at the lower end of said frame to facilitate horizontal movement of the frame in a direction perpendicular to the horizontal direction of movement of the auxiliary frame, means extending between said carriages to cause movement of the auxiliary carriage from an operative position to an inoperative position, said auxiliary carriage being spring biased to its operative position, said means extending between the carriages being pivoted to said main carriage for cooperation with an actuator depending from said auxiliary carriage, a horizontally disposed plate member on said auxiliary carriage for supporting articles to be transferred onto a shelf, a lane actuator supported by the auxiliary carriage, motor means on one of said carriages for driving said lane actuator, said lane actuator being adapted to cooperate with structure on a shelf for retracting a lane pusher to a reloading position, and a movable guard on said auxiliary carriage for preventing contact between said lane actuator and articles to be transferred from the plate member to a shelf.

Claim 13

Apparatus for loading articles into lanes on horizontal shelves comprising a loading frame, a main carriage supported by said frame for vertical movement, an auxiliary carriage supported by said main carriage for horizontal movement relative to the main carriage, support wheels at the upper end of said frame and guide wheels at the lower end of said frame to facilitate horizontal movement of the frame in a direction perpendicular to the horizontal direction of movement of the auxiliary frame, means extending between said carriages to cause movement of the auxiliary carriage from an operative position to an inoperative position, said auxiliary carriage being spring biased to its operative position, said means extending between the carriages being pivoted to said main carriage for cooperation with an actuator depending from said auxiliary carriage, a horizontally disposed plate member on said auxiliary carriage for supporting articles to be transferred onto a shelf, a lane actuator supported by the auxiliary carriage, motor means on one of said carriages for driving said lane actuator, said lane actuator being adapted to cooperate with structure on a shelf for retracting a lane pusher to a reloading position, and a movable guard on said auxiliary carriage for preventing contact between said lane actuator and articles to be transferred from the plate member to a shelf.
