Definitions
- a device of this type is known for example from DE-PS 934 770.
- the sheet transport system is designed here as a gripper arrangement for a printing cylinder and regulates the gripper pressure at the sheet leading edge, taking into account the tensile load.
- the gripper assembly consists essentially of a gripper shaft with a roller lever which rotates on a control cam.
- the gripper shaft is additionally loaded positively in the gripper closing direction by means of a compression spring arranged on a rod.
- cam control By means of cam control, the gripper shaft is opened against the spring force.
- the spring force can remain unchanged or reduced, in which the compression spring-carrying rod is extended and is paired gearbox with a hinged lever on the cylinder and rollers with an additional cam control.
- a control device for grippers in turning drums On a gripper shaft a gripper shaft lever is arranged, which carries a cam roller at the end.
- the force-loaded by a tension spring cam roller is paired with a curved path.
- the cam track is integrated inside a roller lever end and the cam roller protrudes into the roller lever in order to form the cam joint with the curved path.
- the roller lever has a pivot point and carries at the end facing away from the curved track further a role, which paired with a control cam forms another curve joint.
- the roller lever is in addition with a compression spring in functional connection, which performs the role frictionally on the control cam.
- Fig. 1 generally for a sheet guiding cylinder.
- the kinematic scheme shows a hinge 1, which is arranged gear frame fixed to the sheet guiding cylinder.
- Fixed frame is hereby the rotating sheet guiding cylinder, for example in the form of a printing cylinder 25, a turning drum 23, a transfer drum 24, a collision drum or a vibrating pre-gripper system (the latter not shown) to understand.
- a curve rocker 2 is articulated end, which carries at the free end with a fixed curve 4 operatively connected roller 3.
- a rotary joint 6 is arranged, which is connected to a coupling 7.
- the rotary joint 6 (with articulated coupling 7) can also be arranged in the axis of rotation of the roller 3.
- the coupling 7 is further connected to a arranged on a separate rocker pivot 13 8.
- the coupling 7 is thus geared a binary member with two pivot joints 6, 8.
- the rocker 13 is a frame-fixed pivot 10 is arranged on the sheet guiding cylinder and has between the swivel joints 8, 10, a further rotary joint 9.
- the law of motion of the curve 4 is known to provide the highest and lowest points on the cam member in order to realize the desired: time-expiring, periodic movements.
- Gearbox form roller 3 and curve 4 at the mating a curve joint, the roller 3 is frictionally secured by the energy storage 12, for example, a spring system with compression spring or tension spring in their forced operation.
- a defined force for the forcible securing of roll 3 and curve 4 in the curved joint is maintained with the control device according to the invention essentially over the entire law of motion. It is realized by the fact that the rocker 13 mounted on the turning drum 23 fixed to the frame in the rotary joint 10 has two rotary joints 8, 9.
- the rocker 13 compensates for the forces resulting from the law of motion of the curve 4 and usually causing load change reactions by the swinging movement of the rocker 13 about the pivot 10, the lever ratios and the force ratios and thus change the moments.
- the rocker 13 is shown pivoted about the axis of rotation of the rotary joint 10 when the cam joint (roller 3, curve 4) occupies approximately the lowest point on the cam body of the curve 4. This corresponds to the position shown in FIG. 2 with solid lines.
- a force F 1 acts, which with a lever arm I 1 (solder from the pivot point 10 on the force direction F 1 ) results in the moment M 1 .
- a force F 2 acts on the coupling 7, a force F 2 , which with a lever arm I 2 (Lot of the pivot point pivot 10 on the direction of force F 2 ) results in the moment M 2 .
- the rocker 13 with hinges 8, 9 is formed with the lever arms I 1 , I 2 such that at the lowest point of the cam (curve 4) for the lever ratios applies: I 1 > I 2 .
- the rocker 13 is pivoted about the axis of rotation of the pivot 10 in the position shown when the cam joint (roller 3, curve 4) approximately the highest point on the cam body (curve 4) occupies. This corresponds to the position shown in dashed lines in Fig. 2.
- a force F 1 ' which results in a moment arm M 1 ' with a lever arm I 1 ', acts.
- F 2 ' acts at the coupling 7 acts a force F 2 ', which results with a lever arm I 2 ' the moment M 2 '.
- the lever ratios I 1 ' ⁇ I 2 '.
