Abstract
Abstract A palletizing robot for displacing stackable objects, particularly for printed products arranged in stacks, including a gripping device arranged at an arm driven to rotate about a vertical axis, a horizontally oriented transverse member including a track along which the rotatably mounted arm is guided so as to be displaceable in the direction of the transverse member and a bearing rotatable about a vertical axis for the gripping device. The part of the arm extending in the horizontal direction is here disposed below the transverse member and the gripping device is furthermore arranged so as to be vertically displaceable by a predetermined lifting movement, particularly a lifting movement of a few centimeters, in the horizontally extending arm.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
141 words
A palletizing robot for moving stacked objects, comprising: a substantially horizontal transverse member; a track means disposed on and extending along said transverse member; a support bearing means slidably disposed on said track means; an arm having first and second ends, said first end being rotatably attached to said bearing means for rotation about a substantially vertical axis, and said second end being vertically spaced below said transverse member; a gripping device for grasping stacked objects; said gripping device being pivotally attached to said second end of said arm for rotation about a substantially vertical axis; a guide means extending vertically downwardly from said second end of said arm for guiding said gripping device for vertical displacement thereon towards and away from said second end; and means for vertically displacing said gripping device on said guide means by a predetermined amount.
Claim 2
Dependent Claim
141 words
A palletizing robot for moving stacked objects, comprising: a substantially horizontal transverse member; a track means disposed on and extending along said transverse member; a support bearing means slidably disposed on said track means; an arm having first and second ends, said first end being rotatably attached to said bearing means for rotation about a substantially vertical axis, and said second end being vertically spaced below said transverse member; a gripping device for grasping stacked objects; said gripping device being pivotally attached to said second end of said arm for rotation about a substantially vertical axis; a guide means extending vertically downwardly from said second end of said arm for guiding said gripping device for vertical displacement thereon towards and away from said second end; and means for vertically displacing said gripping device on said guide means by a predetermined amount.
Claim 3
Dependent Claim
15 words
A palletizing robot as defined in claim 1, wherein said transverse member is horizontally displaceable.
Claim 4
Dependent Claim
30 words
A palletizing robot as defined in claim 1, further comprising means for rotating at least one of said arm and said gripping device through a rotation angle greater than 360°.
Claim 5
Dependent Claim
25 words
A palletizing robot as defined in claim 1, further comprising a control unit for coordinating picking up and stacking of objects by said gripping device.
Claim 6
Dependent Claim
25 words
A palletizing robot as defined in claim 4, wherein said control unit comprises a memory for storing a predetermined palletizing scheme for palletizing stacked objects.
Claim 7
Dependent Claim
25 words
A palletizing robot as defined in claim 4, further comprising a vertically movable lifting table for receiving a plurality of layers of stacked objects thereon.
Claim 8
Dependent Claim
115 words
A palletizing robot as defined in claim 6, wherein said control unit comprises a light barrier means for detecting a presence or an absence of a layer of stacked objects received on said lifting table, said control unit causing said lifting table to be raised by a predetermined amount when said light barrier detects and unobstructed passage of light during the removal of stacked objects, and said control unit causing said lifting table to be lowered by a predetermined amount when said light barrier fails to detect light during the addition of stacked objects stacks, whereby said control device layer ensures the removal and production of layers of stacked objects according to a predetermined scheme.
Claim 9
Dependent Claim
101 words
A palletizing robot as defined in claim 7, wherein said light barrier means comprises one of a light receiver and a plurality of light receivers linked together by an OR circuit; further wherein said light barrier means comprises a plurality of light sources for emitting a plurality of beams adjacent a surface of said lifting table, the spacing between adjacent ones of said beams being less than an edge length of a layer of stackable objects to be received on said table, and said plurality of beams is directed at one of said light receiver or said plurality of light receivers.
Claim 10
Dependent Claim
17 words
A palletizing robot as defined in claim 1, wherein said gripping device includes a quick release coupling.
Claim 11
Dependent Claim
18 words
A palletizing robot as defined in claim 1, wherein said arm is a member of elongated box shape.
