Abstract

Device for manipulating a flat object (1), comprising a lifting hook (2) and a traverse (4) with suction cups (5), which are evacuated by a vacuum pump (6). The traverse is connected to the hook via a bearing structure (7), so that the traverse can be rotated (R) and be tilted (K). The vacuum pump tilts but does not co-rotate with the traverse and the object.

Claims3

Dependent claims

A device for manipulating a flat object, comprising:

a lifting hook which is adapted to be able to be connected to a hoisting device, further comprising a suction cup frame, hereinafter referred to as traverse, provided with a number of suction cups, which can engage the flat object;
wherein the connection with the flat object is established by creating a vacuum in the suction cups by means of a vacuum pump, which is part of the device;
wherein the traverse is connected to the lifting hook in such a way, by means of a bearing structure, that the traverse can be rotated in the plane of the object to be manipulated, and also can be tilted in the transverse direction;
wherein the bearing structure comprises a rotary bearing and a pivot bearing, which rotary bearing comprises an outer bearing member connected to the traverse and an inner bearing member, such that the traverse has a center of rotation;
wherein the rotary bearing is positioned within the thickness of the traverse or in the space between the traverse and the surface of the object to be manipulated, during use of the device;
wherein the pivot bearing is connected with the lower end of the lifting hook by means of a first bearing portion, wherein the pivot bearing has a center;
wherein the pivot bearing is connected to or is part of the inner bearing member of the rotary bearing by means of a second bearing portion, which is tiltable relative to the first bearing portion, wherein the pivot bearing has a point of engagement with the rotary bearing;
wherein the center of the pivot bearing is positioned at the center of rotation of the traverse;
wherein the point of engagement is located inside the plane of the rotary bearing;
and
wherein by means of a mounting frame the vacuum pump is connected to the second bearing portion of the pivot bearing or with the inner bearing member of the rotary bearing, in such a way that, during use of the device, the vacuum pump co-tilts with the traverse and the object to be manipulated, but does not co-rotate with the traverse and the object to be manipulated.
