Abstract
A clamping element for attaching a gripper onto a clamping tongue as well as a gripper with this kind of clamping element is provided. The clamping element has a longitudinal carrier the width of which substantially corresponds to the width of the clamping tongue and at least two mutually distanced clamping regions. At least one fastening element for the detachable fastening of the clamping elements to the clamping tongue (42, 44) is provided. The clamping element provides an improved force division as well as a secure support on the clamping tongue.
Claims17
In a gripper for gripping an object, wherein the gripper comprises a T-shaped clamping tongue having a central clamping tongue part and first and second arms laterally protruding from opposite sides of the central clamping tongue part, a clamping element, the clamping element comprising:
- an elongated carrier, the length of which substantially corresponds to the distance from a distal end of the first arm to a distal end of the second arm;
- at least two mutually distanced clamping regions, on the elongated carrier, in which the clamping element, when in use, acts together with a gripped object or a counter clamping tongue, respectively, wherein the clamping regions are arranged on the elongated carrier such that, when the clamping element is attached to the clamping tongue, they are located in the regions of the first and second arms;
- at least one fastening element for detachable fastening of the clamping element to the clamping tongue.
Gripper for gripping flat objects, in particular printed products comprising:
- a first and a second clamping tongue that are pivotable in relation to one another about a pivot axis, such that the gripper may be brought into an open configuration or closed configuration respectively, wherein at least the first clamping tongue is T-shaped and comprises a central clamping tongue part and first and second arms protruding laterally from opposite sides of the central clamping tongue part;
- clamping force generating elements for generating a clamping force between the clamping tongues in order to press the clamping tongues against each other in the closed configuration;
- clamping elements that are arranged on distal ends of the clamping tongues, wherein the clamping elements of both clamping tongues lie on each other or on the flat object other in the closed configuration;
- wherein at least one of the clamping elements comprises
- an elongated carrier, the length of which substantially corresponds to the distance from a distal end of the first arm to a distal end of the second arm;
- at least two mutually distanced clamping regions, in which the clamping element, when in use, acts together with a gripped object or the other clamping tongue, respectively, wherein the clamping regions are arranged on the elongated carrier such that they are located in the regions of the first and second arms;
- at least one fastening element detachably fastening the clamping element to the clamping tongue.
