Abstract
A telescopic arm of a load-handling system for transferring storage units into and out of a rack stage of a racking system is displaceably supported on a support frame and has a plate-shaped middle slide and a plate shaped top side displaceable relative to the support frame and to each other. The support frame is in the form of a hollow section and has first and second upright longitudinal side walls and a bottom and a top side wall. Lateral guide tracks and a vertical guide track are arranged on the first upright longitudinal side wall. The top slide has lateral guide tracks and a vertical guide track as well as movable drivers for pushing a front or rear face of the storage unit. The middle slide is slidably guided between the support frame and top slide.
Claims29
A telescopic arm of a load-handling system for transferring storage units into and out of a rack stage of a racking system,
- (a) the telescoping arm being displaceably supported on a support frame having the form of a hollow section and comprising
- (1) a plate-shaped slide and a plate-shaped top slide, the middle slide and top slide being displaceable relative to each other and to the support frame, and the middle slide being slidably guided between the support frame and the top slide,
- (b) the support frame comprising
- (1) a first upright longitudinal side wall directed towards the middle slide, a second upright longitudinal side wall opposite the middle slide, a bottom side wall and a top side wall, the bottom and top side walls extending between the upright longitudinal side walls, and
- (2) lateral guide tracks and a vertical guide track arranged on the first upright longitudinal side wall between the longitudinal peripheral regions of the bottom and top side walls for laterally and vertically guiding the middle slide along the support frame, each guide track extending in the longitudinal direction and essentially along the entire length of the support frame,
- (c) the top slide comprising lateral guide tracks and a vertical track guide directed towards the support frame, each guide track extending in the longitudinal direction and essentially along the entire length of the top slide,
- (d) the middle slide comprising oppositely disposed sidewalls and guide lands arranged on both of the oppositely disposed side walls and protruding into said lateral and vertical guide tracks of the support frame and the top slide, each guide land extending in the longitudinal direction and essentially along the entire length of the middle slide,
- (e) at least two drivers arranged on each distal end region of the top slide, the drivers being displaceable transversely to the longitudinal direction of the top slide from a rest position into an operating position, whereby a respective one of the drivers in the rest position is able to be positioned in a seating region in the top slide and, in the operating position, the driver projects beyond an external boundary of the top slide and overlaps a respective one of the storage units at one of two opposing front and rear side faces thereof relative to an extension direction of the telescopic arm, and
- (f) an actuator motor arranged on the top slide for moving each driver between the rest and operating position.

A load-handling system arranged on a vertically and horizontally movable loading platform of a conveyor vehicle for transferring storage units into and out of a rack stage of a racking system, comprising
- (a) two telescoping arms synchronously displaceable and supported on two support frames having the form of a hollow section, the support frames extending parallel to, and at a distance from, each other, each telescopic arm comprising
- (1) a plate-shaped middle slide and a plate-shaped top slide, the middle slide and top slide being displaceable relative to each other and to the support frame whereon it is supported, and the middle slide being slidably guided between the support frame and the top slide,
- (b) each support frame comprising
- (1) a first upright longitudinal side wall directed towards the middle slide, a second upright longitudinal side wall opposite the middle slide, a bottom side wall and a top side wall, the bottom and top side walls extending between the upright longitudinal side walls, and
- (2) lateral guide tracks and a vertical guide track arranged on the first upright longitudinal side wall between longitudinal peripheral regions of the bottom and top side walls for laterally and vertically guiding the middle slide along the support frame, each guide track extending in the longitudinal direction and essentially along the entire length of the support frame,
- (c) the top slide comprising lateral guide tracks and a vertical track guide directed towards the support frame, each guide track extending in the longitudinal direction and essentially along the entire length of the top slide,
- (d) the middle slide comprising oppositely disposed sidewalls and guide lands arranged on both of the oppositely disposed side walls and protruding into said lateral and vertical guide tracks of the support frame and the top slide, each guide land extending in the longitudinal direction and essentially along the entire length of the middle slide,
- (e) at least two drivers arranged on each distal end region of the top slide, the drivers being displaceable transversely to the longitudinal direction of the top slide from a rest position into an operating position, whereby a respective one of the drivers in the rest position is able to be positioned in a seating region in the top slide and, in the operating position, the driver projects beyond an external boundary of the top slide and overlaps a respective one of the storage units at one of two opposing front and rear side faces thereof relative to an extension direction of the telescopic arm, and
- (f) an actuator motor arranged on the top slide for moving each driver between the rest and operating position.
