US 2025/0145390 A1 · GRIPPER HEAD AND METHOD FOR HANDLING PACKAGING BLANKS

Abstract

A gripper head (10) for manipulating packaging blanks is disclosed. The gripper head (10) comprises an upper gripping unit (17) and a lower gripping unit (19) which are configured for the joint tight gripping of a plurality of packaging blanks from a stack (50) having a large number of packaging blanks. Furthermore, the gripper head (10) comprises a separating unit which is configured to lift outer edges of given packaging blanks intended for being tightly gripped. The separating unit comprises a linear actuator (16) for lifting the outer edges, which actuator is arranged in such a way that its rectilinear lifting axis is inclined relative to a contact surface of the lower gripping unit (19) when the separating unit (18) lifts the outer edges of the given packaging blanks via the linear actuator (16).

A system for manipulating packaging blanks, comprising:

a gripper head having:
an upper gripping unit (17) and a lower gripping unit (19) which are configured to grip one or more packaging blanks from a stack (50) of packaging blanks, and
a separating unit (18) which is configured to lift outer edges of packaging blanks intended to be gripped relative to packaging blanks remaining on the stack (50) so that the lower gripping unit (19) can be inserted into the stack (50) of packaging blanks in the region of the raised outer edges,
wherein the separating unit (18) comprises a linear actuator (16) which is arranged in such a way that its rectilinear lifting axis (HA) is inclined relative to a contact surface (24).

A method (100) for manipulating packaging blanks via a gripper head (10) which possesses a lower gripping unit (19), an upper gripping unit (17), and a separating unit (18), wherein a stack (50) of packaging blanks is provided, the method comprising:

lifting, with the gripper head (10), outer edges of given packaging blanks to be clamped relative to further packaging blanks remaining on the stack (50) wherein the lifting step comprises actuating at least one linear actuator (16) of the separating unit (18) which takes place along a rectilinear lifting axis (HA), wherein rectilinear lifting axis (HA) is inclined relative to a contact surface (24) for packaging blanks,
introducing the lower gripping unit (19) into the stack (50) of packaging blanks in the region of the raised outer edges,
gripping the packaging blanks with the lower gripping unit (19) and the upper gripping unit (17), and
moving the gripper head (10), together with the gripped packaging blanks away from the stack (50).
