Patent ID: 8074484

Claim:
Manipulation device for manipulating a workpiece on a bending press, comprising multiple successive moving elements in the form of articulated arms connected to one another via articulated joints, wherein one moving element has a rotary head which is rotatable about a rotational axis which at least approximately coincides with a center axis of the moving element, and comprising a gripping device connected thereto having a gripping zone, formed by one or more gripping elements, by means of which the workpiece may be held in the gripping zone, wherein the gripping device is connected to the rotary head via a boom element extending along a boom longitudinal axis, by means of which a midpoint of the gripping zone is situated at a distance from the rotational axis, and further comprising an adjustment device on the boom element by means of which the position and/or angular orientation of the gripping device and the gripping zone with respect to the boom element may be adjusted in at least two different working positions; wherein the adjustment device includes a linear drive and a linear guide on the boom element, the linear drive and the linear guide being operable to move the gripping device along the boom element so as to adjust a position of the gripping zone, and correspondingly a position of a workpiece held in the gripping zone, along the boom element, wherein the linear guide lies in a plane perpendicular to the rotational axis of the rotary head, and wherein a primary axis of the gripping device may be oriented transverse to the boom longitudinal axis, and in this position the midpoint of the gripping zone is thus situated at a gripping distance from the boom longitudinal axis.
