    The gripper control quadrant is for the gripper arms of sheet processing machines, esp. for printing machines. A cam controls the opening and closing movement of the grippers. The angle between the cam roller and the lift curve is constant for all gripper opening points. The gripper opening cam is made in one piece and is located concentric to a circular shaped carriage reversing track. The inlet curve is constructed as a constantly changing radius of curvature.

    The invention relates to a cam for controlling grips in sheet-feeding devices TBax of sheet-processing machines, in particular printing machines, has a starting curve and a running curve.
    Known gripper control cam (1) E - AS 2040 670) in leaflet devices of printing machines. Cam divided. It consists of a cam to open the grippers and a cam to close the grippers, and the cam to open the grippers is designed as a straight through most of its length of the connecting rod of the three-link crank-crank mechanism with crank arms of equal length.
    Such an arrangement of the gripper control cam serves to ensure the most mixing, while maintaining a constant starting angle.
    The disadvantage of this cam is that the cam of the cam and the cam of the cam are not composed of one part, but are separated. Thus, the cam does not have a closed treadmill.
    Due to the interrupted running surface between the opening cam and the closing cam, there are jumps in the shape of a curve, which results in an increased cam roller and the running surface. In addition, a running track interrupted causes a lot of noise. In addition, wear is enhanced by the fact that in the transition zone of the cam, the cam roller closes the cam roller only on the width of the running surface reduced by approximately 50%, and in this zone the grippers are maximally open, i.e. by means of the spring, the openings of the grippers act as much as possible on the system of force on the cam roller, and thus on the cam. With a reduced running surface, therefore, an increased specific pressure appears.
    In addition, the cam is designed as a connecting rod. As a result, the cam does not directly open on the machine frame, but with the help of intermediate links. The supports between the connecting rod and the arms of the lever are loaded with each turn of the roller. This leads to an increase in clearance in the bearing and, thus, contributes to wear and noise.
    In addition, the manufacture of the gripper control cam is costly.
    The aim of the invention is to create a gripper control cam with a simple design, realizing a larger displacement range, which works with a slight noise and, moreover, has a greater wear resistance.
    The object of the invention is to create a gripper control cam in leaf-cutting devices which has between itself a gripping opening curve and a gripping closing curve of itself in itself a closed treadmill and has a constant initial angle for a roller and a constant law of running over its range of motion.
    The goal is achieved by the fact that the one-part and equipped with the initial curve and the runaway curve the gripper control cam is located concentrically relative to the track of the guide carriage, and the initial curve has a continuously varying radius of curvature.
    The gripper control cam is located directly on the machine frame and is designed as a backstage of the mating mechanism. The gear unit consisting of a hand lever, an adjusting shaft and a worm gear is located in front of the mating mechanism. ,
    According to another embodiment, the installation gear is directly located on the gripper control cam. The direction of the tension spring force and the direction imposed by the roller on the gripper control opening force cam are approximately parallel. The shape of the initial curve corresponds predominantly to the trochoid form. Such an arrangement and positioning of the gripper control cam has the advantage that it has a closed cam path, as a result of which, cam form non-impediments and, thus, increased wear and tear effects on the cam track and roller are avoided. The closed cam path ensures that the roller roller on the track rolls off with a slight amount of noise. Continuously varying the passage of the initial curve, which mainly corresponds to the trochoid shape, provides a constant starting angle of the roller to the cam track within the turning zone 1 .VV-lYyi / J.Ul kJIlV IJ-ll.L1i1ll... Cam controlled by the grippers, i.e. for all points of opening of the grippers. As a result of the positioning of the cam, the gripper controls as a link and the resulting direct races. The position on the machine frame reduces the bearing gap, and the opening forces of the grippers are directly transmitted to the machine frame. Due to the reduction in the number of supports, wear is reduced. The gripper control cam has a simple design and is, by simple means, pivoting around the cam support pin. FIG. 1 shows a detail of a leaflet device with a gripper control cam; in fig. 2: Another possible movement of the gripper control cam. On-FIG. Figure 1 shows a part of a sheet-holding device of a printing machine with a receiving slip 1 and a guide carriage 2 in which the carriages with the grippers 3 are at a constant distance. The carriage with grippers 3 consists of gripper 5 and roller lever 6, on which cam roller 7 is located. On receiving receiving 1, front stops of berth 8 are installed. In the zone of sheet release, the carriage from gripper 3 is located on support pin 11 concentric to circular track carriages. 9 is a cam for controlling grippers 10, which consists of an initial curve 10.1 and a running curve 10.2. The cam for controlling the grippers 10 is connected via the rod 12 and the lever 13 to the transverse shaft 14 placed in the machine bed. The lever 13, the connecting rod 12 and the cam for controlling the grippers 10 relative to the drive are connected with a pin 15 in the order named. These elements form the conjugate mechanism 13,12DO, and the cam for controlling the grippers 10 is designed as a link. On the transverse shaft 14, there is a worm gear 16, with which the worm to the 18 located on the adjusting shaft 17 is in engagement. The worm gear 16 and the worm to 18 form a worm gear 16.18. The mounted shaft 17 is located in the machine bed and is equipped with a hand lever 19. To eliminate all the gaps in the sub-holder in the mating mechanism 13, -12.10 and in the worm gear 16.18 is located on the gripper control cam 10 mounted on the statin of the tension spring 4, the direction of the forces of which passes approximately parallel to the direction produced by the roller 7 on the control cam of the grippers 10 of the gripping forces. According to another embodiment,, l r of FIG. 2 worm gear 16. 18 is located directly on the gripper control cam 10. There are no advantages for action. In the exemplary embodiment, a carriage with grippers 3 is directly located on a chain wheel. But it is also possible to drive the carriage with grippers 3 along a separate path and using a connecting rod to pivotally connect with the chain wheel. The principle of operation of the device is as follows: The sheet 20 received by the gripper 5 of the carriage with the grippers 3 from the last non-illustrated printing section is fed through the receiving slide 1, released by the gripper 5 is laid down on the receiving slip 1. The release of the sheet 20 causes the roller 7 to fly over the initial curve 10.1 as a result, the lever 6 is rotated and the grip 5 is opened. The gripper 5 is kept open in the entire zone of the receiving jig 1 at the point of release of the sheets until the roller 7 rolls down the 10.2 curve and the gripper 5 is closed with an un-displayed gripping spring. Necessary changes in the opening point of the grippers, for example, in the processing of other printed material, are achieved by turning the cam of the gripper control 10 around the bearing pin 11, and turning to the right causes a earlier opening and turning to the left later opening of the gripper 10. The turning movement of the gripper of the gripping control 10 is transmitted manually the lever 19, the setting shaft -17 and the worm gear 16, 18 to the transverse shaft 14, and with its help it is transmitted through the lever 13 and the rod 12 to the gripper control cam
    10. According to the embodiment of FIG. 2, the setting movement is directly transmitted by the worm gear 16, 18 to the control cam of the grippers 10.
    It is recognized as an invention according to the results of the examination carried out by the Office for the Invention of the German Democratic Republic.
