    Feeding device for feeding paper sheets from a pile, particularly in offset printing machines. The device has a driving mechanism, the operation of which is controlled by three sets of two cams in precise intervals according to the program of operation of the printing machine. All control mechanisms have their operation motions designed separately in such manner, that each mechanism is controlled by one set of two cams. The advantage of the said feeding device consists in that the control mechanism perform precise operations in accordance with the program of operation even at high printing speeds, because they are controlled bilaterally by the set of two cams and double rollers without employing spring elements to cause cam followers to remain in contact with cam surfaces.

    This invention relates to a sheet feeder for feeding sheets of paper on offset presses.
    The famous samonaklad is known (CS certificate No. 181553, class B 65 N 5/08, 1977), in which the drive of the control mechanism for the movement of the suction cups and the calipers are removed from the cams in cooperation with elastic elements.
    The disadvantage of this feeder is that at higher printing speeds, the control mechanism rollers do not learn the shape of the control cams and, as a result, sources appear in the control functions.
    Known feeders are designed so that the movements of the mechanisms
    The controls are ejected from one drum cam, and the mechanism for controlling the suction cups is controlled by one double-sided cam track and a fixed, vertically positioned slide with a shaped groove. The caliper mechanism is controlled by a one-way drum cam path and an elastic element. The disadvantage of this device is that the actuator is suitable only for simple universal suction cups, which are designed for both lifting sheets and transporting them. A device that cannot be used for separately working systems with suction cups, when one system of suction cups lifts the sheets, and

    friend's sheets submits to the printed ma- | tire. In addition, the elastic elements for controlling the calipers cause its inaccurate function,
    The closest to the well-known is the feeder, in which on the drive shaft, located in the body of the feeder, there is a pair of levers with a pair of first rollers extending to track 10 of the first double cam, a control fork with a pair of second rollers adjacent to the tracks of the second double cam , and a lever with a pair of third rollers adjacent to the road-15 of the third double-cam cam, and in the fork-shaped arms of the pair of lever, the rods are rockingly fixed by one end, which are fixed by a second end on the carrier tube, equipped with suction cups. In the control fork there is a carrier tube with front conveying suction cups fixedly connected to the sucker rod, on which the rear conveying suction cup is located, with a guide roller fixed to the sucker rod, placed in a guide fixed in the body of the suction head, In the forked part at the end lever arm tilting the crosspiece with a through hole in which one end is placed, t ha with a spring. At the lower end by means of a pin secured; 35 a caliper, and a swinging fork, which with the other end is located on the spigot fixed in the body of the feeder. A tetrahedral nut is fixed at the end of the thrust, which 40 is placed in the fork-shaped part of the lever, with the spring attached at one end to the cross and the other end to the step of the thrust.

    The premise of this samonaklada, is that the control mechanisms perform an exact function on the working diagram also at high printing speed, since they are controlled by double cams and pairs of rollers without npuMBHeHtm spring elements. In addition, the genuine calipers' cushioning was made - only in the range of the difference in the value of its lifting of the overhead table, and, in fact, the driving mechanism does not contain any prediction elements.

    Both systems have suction cups, i.e. lifting and transporting suction cups are independently in exact intervals set by cams, the control curves of which correspond to the working diagram of the feeder.
    The aim of the invention is to increase the reliability of the operation of the feeder.
    Fig. 1 shows a frontal projection of the feeder in the lifting position of the caliper, longitudinal section; Fig. 2 shows a frontal projection of the feeder in the position of the caliper against the stack of sheets, a longitudinal section; in fig. - horizontal projection of the feeder, partial incision, I
    The feeder consists of a housing 1 in which a drive shaft 3 is placed by means of a bearing 2. The first double cam 4 is fixed on the latter for controlling the suction pad 24, the second double cam 5 for controlling the conveying suction cups 12 and 13 and the third double cam b for controlling the caliper 7 A hub 9 is placed in the housing 1 of the self-roll by means of bearings 8, on which by means of bearings 16 is placed a pair of levers 17, whose arms are fork-shaped. In addition, on the trunnion 9 a control fork 10 is placed and by means of bearings 22 a lever 23 is rockingly fixed, the arm of which is fork-shaped at the end. Pair pbK ar.: 7 is equipped with a pair of first rollers. ., each of which is adjacent to the track of the first double cam 4. The control fork O is provided with a pair of second rollers 38, each of which is adjacent to the corresponding track

    the top end of the four-sided nut 40,20 caliper 7 is adjacent to the foot 35
    which is protected from rotation by placing it in the fork-shaped part of the lever 23. On the holder 31, the caliper 7 by means of the pin 27 is fixed at one end by a swinging fork 29, fixed by the other end by means of the pin 33 on the body of the self-roll 1. On the elongated upper part of the holder 31, by means of the connecting pin 34, one end of the swinging arm 30 is fixed, suspended by means of the axle 36 on the body of the feeder 1. The caliper caliper 7 is attached to the foot of 35 sheets, with the front piping caliper 7 moving along a curved path 28. A guide 15 is fixed on the body of the self-groove 1, in which the guide roller 1 4 is rolled, mounted on the suction rod 43, on which the rear roller is placed - a suction cup 13. The body 1 of the feeder is fixed with the possibility of shifting on the carrier element 41 fixed on the sides of the printing press. - The mechanism of the feeder is protected by a casing 42, on the running on the case of the 1st feeder.
    Samonaklad works as follows.
    By rotating the shaft; its shaft 3 drives the double cams 4 to 6. The rotation of the first double cam 4 transmits by means of the first rollers 37 a motion to a pair lever 17, from which it is transmitted by means of connecting rods 19 and a carrying tube 20 to the suction pads 21.

When the calipers 7 are attached to the foot 35, the lever 23 continues to move and the crosspiece 25 compresses the spring 32. The latter is compressed only in the range of the difference in the amount of lifting of the overlay table on which the foot of 35 sheets of paper is located. The spring 32 provides only an elastic fit for the caliper 7 to the foot 35, and the reverse movement: the caliper caliper 7 to the upper floor; again, it is controlled by a double cam 6,
