Embodiment Construction

[0022] figure 1 The orientation device 10 is shown in a view from below, which, viewed in the transport direction T, is arranged between the feeder 20 and the sheet processing machine 30 . The sheets 100 from the feeder 20 are grasped by the orientation device 10 , aligned and forwarded to the gripper 31 of the sheet processing machine 30 .

[0023] The orientation device 10 has a contact element 2 which figure 1 In an embodiment, it is configured as a suction plate. The contact element 2 is formed symmetrically with respect to the center axis, wherein, at figure 1 Only one half is shown in . The contact element 2 can be moved by the three drives 1 in its degrees of freedom 5 firstly in the circumferential direction, ie in the conveying direction T, secondly transversely to the circumferential direction T and thirdly by rotation in an orientation plane, whereby The corresponding sheet 100 can be oriented. For this purpose, the contact element 2 has a plurality of suction ...

Abstract

The invention relates to a device (10) for the alignment of sheet-shaped elements (100) in a plane with at least two degrees of freedom (5) movable and changeble contact elements (2) and at least two controllable drives (1) for moving the contact element (2). According to the invention, the changeable contact elements (2) include at least one switch (3) having at least two switching positions and the device (10) comprises a counter element (4) associated with the respective switch (3), wherein the at least one switch (3) and the at least one counter element (4) can respectively and mutually be in mechanical engagement so as to adjust the at least one switch (3). This solution has the advantages that no additional free actuator is required and that the change of the contact elements requires no intervention of machine operators.

Description

technical field [0001] The invention relates to a device for orienting sheet-shaped elements according to the preamble of claim 1 . Background technique [0002] A device is known from DE 4406740 A1, which supplies the sheets to a sheet processing machine precisely in register. For this purpose, the device has a suction beam which sucks and thus holds the respective sheet. The suction beams can be adjusted motorized in three degrees of freedom in the orientation plane and thereby bring about an orientation of the respective sheet: orientation in the circumferential direction, orientation transverse to the circumferential direction and rotational movement in the orientation plane. A disadvantage of this device is that no adaptation of the suction strip to the sheet format is provided. If all the suction openings of the suction strip are not covered by the corresponding sheet, the suction pressure will collapse and the function of the suction strip will be canceled. In orde...
