    This invention relates to a transport device for moving fresh prints from a printing press to an exit pile or to another printing press. The purpose of the invention is to improve the quality of prints by uniformly drying them. Figure 1 shows the transporting device in the drying zone, a general view; Fig. 2 shows two chain conveyors with grippers, a side view in Fig. 3, a second chain conveyor with grippers, top view, Fig. 4, section A-A in Fig. 3 (with a gripper shown by broken lines); FIG. 3 is a section b-B in FIG. 3 in FIG. 6, the grippers controlling the grippers (with the position of the rollers at the beginning of the opening of the clamps and at the time of their closing), side view in FIG. 7 - means for adjusting the distance between the claws of the conveyors; on Fig - the same section. A conveyor device for moving impressions from the printing press to the receiving table or to another printing press contains firstly driven chain conveyor 1 carrying the grippers 2 for the front edge of the impression 3, a second chain conveyor 4 carrying the grips 6 for the trailing edge of the impression mounted on the shafts 5 3, the working branch of the second conveyor 4 is parallel to the working branch of the first conveyor 1. In addition, the device includes a support 7 for the claws 6 of the second conveyor 4 mounted on the frame 8, the side parts 9 of which are fixed to the inside The surfaces of the two chains 10 of the second conveyor 4, mounted on each shaft 5 of the grippers 6 of the second conveyor lever 11 for controlling the opening and closing of the grippers 6, the carrier roller 12 and the cam 13 fixed on the frame for interacting with the roller 12. Grippers 2 and 6 of the conveyors 1 and 4, respectively, have a straight line path. The device also has a drive shaft 14 fixed in the side parts 9 of the frame 8, a pin 15 rigidly connected to it for engagement with the gripper support 7, a lever 16 with a roller 17 for controlling the support 7 and mounted on the frame of the cam 18 for engaging the roller 17 the lever 16, while the frame 8 has guides 19 and 20 mounted on its side parts in which the support 7 for grippers 6 is mounted, the latter being spring-loaded with spring 21 relative to guides 19 and 20, and grippers 6 of conveyors 1 and 4 are located in the transport plane print 3. Support 7 for grippers 6 is mounted in guides 19 and 20 by means of locating pins 22. The device has supporting elements 23 for grips 6 of an additional conveyor 4 fixed on support 7 by means of flat springs 24. At the entrance of the first 1 and second 4 conveyors installed floor guide 25 with suction holes 26 for impressions 3. At the exit of the conveyors there is a means for guiding the trailing edge of the impression 3, executed in the form of a cam 27 and connected with it by means of systems 28-31 of the lever 32 located under the plane of movement of the print 3, or air nozzles (not shown). In addition, the device has a means for adjusting
    distance between grippers 2 and 6, respectively, of the first 1 and second 4 conveyors, made in the form of coaxially mounted sprockets 33 and 34, rigidly connected by means of removable screws 35, one of the sprockets 33 being connected to the first conveyor 1, and the other with the second 4, both stars have a drive from the first conveyor 1.
    The device works as follows
    in a way.
    t.
    The impression 3 enters the first conveyor 1 with its front edge held by the grippers, and slides along the support rods 36. When the rear edge of the impression 3 enters the inclined path at the place where the cam 18, schematically shown in FIG. 1. and 6, then the following happens: first the cam 13 touches the roller 12 and therefore rotates the grippers 6 in. Around the shaft 5, after which they open, overcoming the resistance of the spring 37, then the cam 18 touches the roller 17, which moves the gripper support forward , due to this movement, the rear edge of the print is inserted between the open grippers 6 and the supporting elements 23, then thanks to the cam profile.13 the grips are closed, grabbing the rear edge of the impression 3 and also thanks to the corresponding cam profile 13 roller 17 The support of the grippers returns to its resting position, in which the print is tensioned between the grippers 2 and 6. The leaf springs 24, through which the supporting element 23 is hardened, provide sufficient flexibility in gripping the print and eliminate possible damage to its trailing edge. The distance between the series of grips is 6 additional. the conveyor 4 in the transport direction is such that in the resting position of the support 7 of the grippers the impression 3 is tensioned, then As in the extended position of the support 7, the impression 3 is weakened. During the passage of the print 3 in front of the UV drying device 38, it becomes tight, so that the distance between the heat
    926074
    the source and print are
    constant over the entire duration of the passage, which allows for uniform drying of the impression. a 3, except for
    5 taking into account that in this drying zone, as already indicated, there is no other support, since in this zone there are no support rods 36, the heat source does not heat any stationary metal part and, therefore, there is no need to provide a cooling system, as done so far. At the end of this zone is the main;
    (The 5th conveyor 1 is provided with support rods 36 which support the impression 3 as soon as its rear edge leaves the drying zone and a cam (not shown) allows you to open
    20 grip 6 for releasing this edge.
    In order, at the moment when the rear edge of the print 3 should be gripped by the grippers 6, the rear edge of the print 3 is well adhered to the support rods 36, a floor guide 25 is provided, having holes 26 (FIG. 1) connected to the suction system, thus, the rear edge of the print rests when it is caught by the grippers 6. Other means may be provided to secure this fit.
    35 In addition, when the rear edge of the print is freed from the grips 6, in order to avoid rupture of this edge last (the grips sharply change direction, in this area they
    0 actually follow the curvilinear path, as shown in FIG. 1), means are provided for guiding the trailing edge of the impression 3, which has just passed 5 in front of the drying device,
    the trajectory of the grip 6. This tool is schematically depicted in figure 1 and contains a system of t g 28-31, the last of which is fixed on the shaft
    50 39, which can be rotated. The lever 28 is provided with a roller 40 provided for synchronizing the drive cam 27 with the sprocket 41 by means of a belt drive 42. The return spring 43,
    attached at one end to the hook 28 and the other end to the body, allows for contact between
    $
    roller AO and cam 27. The profile of cam 27 is provided in such a way that when the trailing edge of the impression 3 is released by the grippers 6, the system of said tg moves and takes a position (figure 1) in which the curved lever 32 stands in the way of the impression 3 and sharply lifts its rear edge, then it immediately returns to its normal position, in which it passes under the path of this path and is parallel to it.
    To achieve this result, other means can be provided, for example, air hollow nozzles extending from the inner cavity, which can replace the support rods 36, or return the grippers 6 after they have been opened.
    In order to establish the distance between the row of claws 6 of the additional conveyor 4 and the corresponding row of claws 2 of the first conveyor 1 depending on the length of the impressions, a means for adjusting this distance is provided, partially shown in FIG. 7 and 8 This tool contains the first sprocket 33, which is permanently connected by a chain 44 to the first conveyor 1, and an asterisk 34 fixed by six bolts 35, mounted on a shaft 45 belonging to the first conveyor 1, on which another sprocket is attached, (wheel 46) along which the chain of the second conveyor 4 is directed. Thus, the wheels 33 and 34 are mounted coaxially one on another and can be rotated one relative to another pos92607
    To unscrew the connecting screws 35. To do this, a gear 48 is installed on the shaft 47 parallel to the shaft 45, which in the normal position of the scientific research institute exposes to the action of the return spring 49 holding it in the complete position, as shown in FIG. 8 by dash-dotted lines MI, which can be 10 pressed against the action of the spring
    49 to the slave position, as shown in FIG. 8 by solid lines, in which it engages with the teeth 50, executed
    15 on the sprocket 34. Thus, by turning the gear 49 simultaneously with the release of the screws 35, it is possible to move the sprocket 34 with the teeth
    50 relative to wheel 33, i.e.
    20, the distance of the additional conveyor 4 with respect to the main conveyor 1 can be adjusted.
    The invention has been described in connection with its use in devices for transporting impressions in the drying zone, but it is not naturally limited to this application. In particular, such a transportation system may be used to turn the sheets over during their journey. In this case, at the moment when the print goes along a straight path, its front edge is released by the hooks 2 of the conveyor 1 and, by correspondingly bending the path of the second conveyor 4 and turning the hooks of this conveyor, which remain closed, the rear edge of the vice becomes its leading edge.
