    This invention relates to printing. The purpose of the invention is to provide a more uniform distance between the edges of the printed products. A receiving master device is installed under the feather vykladyvatel of the printing press, which has grippers attached to the chain. The grippers capture the printed matter, which is still located in the lifting wheel for its rear ends as it moves. Thus, the printed matter is retained even before it leaves the pen extender. By acting on the edges of the rear edges, the printed products brought into the circulating circulating movement of the tape are pushed into the corresponding cell before being gripped. Therefore, the printed product occupies a certain position in the cell, which allows it to be output from the pen picker in the correct position. 2 s and 8 C. Of p. F-ly, 5 ill. The invention relates to a method and apparatus for receiving, in particular, folded printed products from a rotary pen liner of a printing machine. Printed products coming out of a folding machine of printing machines The inserts are put into the perforated gep compartments, from which the products are then staged on the receiving tapes. For the subsequent further processing of the printed products, it is important that the distances between the steps of the lined step flow are uniform. To achieve this, it is proposed to capture the printed products behind its edges based on the pen spreading units, i.e. to the front in the course of the movement of the edges with the help of controlled grippers before the production has not left the branches (Swiss Patent N; 626830). The gripping hold of the printed products is withdrawn from the pen grab compartments and is staggered onto the diverting conveyor. In order to capture the edges of the printed products reliably enter the grippers, the circumference of the grips is less than the circumferential speed of the base of the pen spreading unit. In this way, the grippers also perform the role of commonly available lifting elements (belt, wheel or the like), against which S00elso > &

    print production and thus extends from the pen reamer.
    The gripping hold of the printed product remains during the slip out of the pen picker in the position that it occupied in the corresponding compartment of the pen putter during its takeover by the hook. However, irregularities in the distance between the steps may occur when the printed product at the time of its capture by the grippers incorrectly abuts on the basis of the separation. In addition, when transferring printed products from to the diverting conveyor installed under them, shifts may occur between successive printed products, which can lead to unevenness in the distances between the steps.
    The known method (European patent laid Mg 0179932), in which printed materials, summed up from above approximately tangentially to the feathers. With its front edge moving along the edge, they are clamped between the walls of the compartments of the pen distributor and the rotating tape, and in the same way they hold the printed products during the rotation of the pen distributor. At the lowest point, the front edges of the printed product are released again and the latter falls onto the conveyor to form the stocks.
    However, in the known method, a uniform distance between the steps cannot be achieved when the printed product cannot fall to the base of the compartments of the feather ejector before it is clamped and held. This, however, does not matter in this well-known device, since the print production is laid out in layers in the stocks, and not processed further in a step form. There is a method in which the printed products in the compartments of the first laying out during the rotation of the first laying out of its front can move along the edges of the movement into cams, which are driven into rotation with a speed less than the speed of the printed products (United States No. 456363, cl. 65 H 29/20, 1987). The printed products, pushed out by the cams from the compartments of the pen spreading device, are laid out in a stepped form on the conveyor. By hitting the printed products on the cams, the first level is aligned, but still during the free fall on the conveyor and, when hit on the last product, it can still shift in its relative position, which leads to uneven distances between the steps.
    In the known device (patent Germany
    Ns 3123406, class In 65 H 9/10), the print production is also aligned by rotational cams, which interact behind the rear edges of the printed products, as the latter is completely free from the pen spreading device. At the moment of impact of the cams on the rear edges of the product, the latter, in the area of the front edges of the movement, is already on the previous product, taken with itself by the receiving laying tape. Due to the friction efforts between the products lying on top of one another, the cams can only greatly change the position of the captured products. This means that large non-uniformities in the distances between the steps cannot be completely equalized. Such irregularities can
    5 appear, for example, when the print production falls into the compartments of the first discharge, wagged in the wrong position, or during the free fall from the compartments to the receiving tape changes its
    0 position.
    The purpose of the invention is to create a device and a method which, simply, as well as at high operating speeds, of the printed products obtained from the pen nest printing press, form a stepped formation with uniform distances between the steps. Printed products should be kept as early as possible, in all cases until complete and out of the branches of the pen pusher, and thus fixed for subsequent formations of the stepped formation in its mutual position. The proposed capture back along
    5, the movement of the production edge allows the required retention of the printed structure by relatively simple means, since this does not require entering the compartments of the pen body. At the moment of capturing in the course of the movement of the edge, the corresponding printed product is in the front area in the direction of the movement of the edge still inside the pen spreading compartment and does not yet lie
    5 or lies only in the posterior region of the edge and is very loose on the preceding printed product, so that before capturing the printed product can no longer undergo an undesirably large change in its position due to capturing with
    a previous printed product through friction effort.
    In order to reliably bring the rear edge along the movement into the zone of action of the grippers, an accelerating device is preferably provided which captures the rear edge of the printed product at the beginning of pushing out of the pen-spreading compartments and guides down to the area of action of the gripper.
    In order to allow the transfer of printed products from the pen dispenser in the correct position, the printed products must already lie correctly in the compartments of the pen dispenser. To ensure this, an alignment device is provided which, before the seizure of the printed products through the grips, acts on the rear ends of the printed products. and inserts the last s of the corresponding compartment of the feather flapper, namely, up to its abutment into the bottom of the compartment.
    In addition, a printed support surface is provided that extends along the feed direction of the receiving master, which has a smaller width than the printed product. When laying out printed matter on a supporting surface, no interfering air cushion can form between the last printed product and the airbag, which could slow down or impede the laying of printed products on top of each other in the correct position.
    FIG. 1 shows a device for receiving and separating printed products pushed out of a printing machine pen, side view, in FIG. 2, the same, top view; in FIG. 3, view A in FIG. 1: in FIG. 4, section B - B in FIG. 3; in Fig. 5, a device for receiving and withdrawing a printed product pushed out of a pen dispenser of a printing machine, an embodiment.
    The device contains a pen vykladyvatel (spreading wheel) 1 of the printing machine, which on its circumference has a large number of open compartments 2 having a bottom 2a. Feather Reaver
    1 is rotated in the direction of arrow B with a peripheral speed Vi. In front of the feathers, the Um spreading device 1 exits the folded printing 4 through the guide roller 3 falls into the compartment
    2Performancer 1. The print production from the folding machine comes out with its edge of the fold 4a forward. This edge of the rebate 4a is viewed in the direction B of rotation of the pen-laying device 1,
    thus becoming a forward edge. Adjacent to the guide roller 3, the guide sheet 5 extends toward the circumference of the pen launcher 1, through which the driven rear edges 4 pass through the rotation of the pen divider 1 in the direction of movement 4c of the printed product 4. For ejecting the printed product 4 from divisions 2 a removal wheel b (if necessary, several removal wheels), which rotates in the direction of the arrow C. Printed products F are hit on the removal wheel
    5 with its forward edge 4a and with the further rotation of the pen spreader 1, they move out of the compartments 2. Instead of the removal wheel, another suitable removal element may be provided, for example an endless belt. The pen spreader 1, together with the lifting wheel 6 and the folding apparatus, are well known structures and thus
    5 principle of operation can be considered known. Under the feather vykladyvatel 1, the receiving master device is installed, the feed direction of which is denoted as D and the feed rate as V2. Direction
    0, feed D has the same direction as the direction of rotation B of the pen rationer 1. Receiving master device 7 (Figures 2 and 3) has two distances 8 and 9 that are parallel to each other and are driven around changing the direction of the wheels 10 and 11 or 12 and 13. The direction-changing wheels 10 and 12 are supported in bearings
    0 rotation on the shaft 14, while the other direction-changing wheels 11 and 13 are mounted on the shaft 15, which is driven through chains 16 and 17 and gear train 17 from the bottom feeder 1 (Figures 1 and 2).
    5 On chains 8 and 9 at equal distances, the grippers 18c are fastened with movable gripping tongues 19. The gripping tongues 19 are a cat part of a yoke 20, which is formed from repeatedly curved strips of spring-elastic material (FIG. 4). Bugli 20 mounted on the housing-holder 21, which is placed on the fingers 22, connected to the chain 8 or 9 and protrude away from it (fig.Z). The casing 5 holders 21 have a surface 21a, which serves as a mating support surface and a catch tongue 19. Further on the chains 8 and 9 are mounted the support rollers 23, on which the shoulder of the spring arm 20 is supported (Fig. 4).
    To open the grip 18, i.e. for lifting the tabs 19 from the mating surfaces 21a, coaxial, with direction-changing wheels 10 13, opening stops 24 and 25 are provided, which are formed by the hubs of the direction-changing wheels 10 - 13. When the chains 8 and 9 change the direction-changing wheel of the bow 20 sections 20a rush over the opening lugs 24 and 25. This is due to the fact that the bows run in the direction away from the opening lugs 24 and 25, as a result of which the gripping flaps rise from the mating support surface 21a (Fig. 4). As soon as the yoke 20 descends from the opening lugs 24 and 25 again, due to its spring-elastic properties, they return to their original position, in which the gripping tabs 19 abut against the mating support surface 21a, and the gripped printed product 4 is pressed against the mating support surface 21 a.
    In the area of direction-changing wheels 10 and 12, i.e. at the beginning of the effective feeding section 7a of the receiving master device 7, a support sheet 26 for printed products 4 is installed between both chains B and 9. The support sheet 26 has a smaller width than the printed products 4.
    A receiving conveyor 28 with the same feed direction E is adjacent to the receiving master 7 (Fig. 1). This withdrawing conveyor 28 preferably has a feed rate Uz, which is slightly larger than the feeding speed V2 of the receiving master 7. For supporting the feed the withdrawal A conveyor roller 28 may be provided above the discharge conveyor 28.
    In the area of the direction-changing wheels and between them there is an acceleration unit 30, which is formed by an endless, rotatable in the direction of the arrow tape 31. The belt 31 is driven through the direction-changing wheels 32-35 (FIG. T). The direction-changing wheel 35 is seated on a shaft 36, which is driven through chains 37 and 37 and a transfer wheel mechanism 38 from shaft 15 (Figures 1 and 2). Lying between the direction-changing rollers 32 and 33, the branch 31a of the belt 31 runs transversely to the feed direction D of the receiving master device 7 and is inclined with respect to the vertical. The guide sheet 5 extends to this effective feed branch 31a (Fig. 1).
    Adjacent to the acceleration unit 30, an alignment unit 39 is provided, which has two infinite ones which are rotated in the direction of arrow C
    ribbons 40 and 41. The ribbons 40 and 41 are driven at a speed Vi, which is greater than the circumferential rotation speed Vi of the pen spreader 1. Both tapes 40 and 41 are driven through reversing wheels 42 and 27, from
    0 of which the direction-changing wheels 27 are seated on the shaft 36. The belts 40 and 41 (Fig. 2) are mounted at a distance from the belt 31 of the accelerating installation 30. The belts 40 and 40 of the belts 40 and 41 are effective in terms of feeding.
    5 extends approximately tangentially to the feather spreader 1, while the effective portion of this effective feed branch 40a is located above the effective portion of the effective feed feed branch 31a of the tape 31.
    The principle of operation of the proposed device is the following.
    From the folding apparatus, the print production 4 falls into the compartment 2 of the pen
    5 spreader 1. During rotation of the pen spreader 1, the back edges of the printed product 4 in the direction of movement 4c are led along the guide sheet 5. During the slide along the guide
    0 sheet 5 of these rear edges 4c, they are adjacent to the tapes 40 and 41 of the leveling installation 39. If the printed product 4 adjacent to the tapes 40 and 41 does not lie correctly in the compartment, i.e.
    5, the upstream edge 4a is not completely adjacent to the bottom 2a of compartment 2, the printed product is sucked into compartment 2 by means of tapes 40 and 41 until it is in the correct position in compartment 2.
    By means of the ribbons 40 and 41 of the leveling installation, all the printed products 4 occupy the correct position in the compartments 2, i.e. with its forward edge 4a adjacent to the bottom 2a of the compartments 2. Thus, a prerequisite is created for late receipt of the printed product 4 from the feather bed 1 in the correct position.
    0 In the course of turning further the pen-laying device 1, the printed product 4, with its forward march of movement, by the edge 4a, encounters the removal wheel 6, as a result of which its obstacle is created
    5, further rotation together with the feather spreading device T and this printing product is pushed out of compartments 2. Already at the beginning of this promotion of printed product 4 its rear end 4c in the course of its movement
    gfihod in contact with the tape 31
    the accelerating device 30 and the feed effective branch 31a of the tape 31 moves down to the receiving master 7. The rear end 4c of the printed product 4 falls on the bearing surface 26 and comes into contact with chains 8 and 9, namely in changing the direction of the wheels 10 and 11, i.e. at the beginning of the effective driving device 7 with respect to the feeding of the portion 7a. As soon as the rear end 4b hits the bearing surface 26 and comes in contact with chains 8 and 9, it is gripped by one of the grippers 18 on chains 8 and 9. These grippers are opened by opening the lugs 24 at the time of raiding chains 8 and 9 to the direction-changing chains of the wheels 10 and 12. As soon as chains 8 and 9 come down from the direction-changing wheels 10 and 12 and the yoke 20 comes off the opening stops 24, both grip 18 is closed in the manner described and firmly rzhivayut movement of the downstream end 4c. At the moment of clamping the downstream end 4b of the grippers 18, the corresponding printed product 4 with its forward end 4a is still in the compartment 2 of the pen otkladyvatel 1, while the captured printed product 4 with its front downstream end 4a still adjoins wheel 6 (FIG. 1). After it is completely out of compartments 2, the printed product 4, held by the grippers 18 in the region of its rear ends 4c, fits completely onto the previous printed product 4. Thus received from feathers the first spreading device 1, the printed products 4, stacked one on top of the other like roofing tiles in the form of a stepped formation, are fed to a diverting conveyor 28 by means of a receiving driver 7. The release of printed products 4 occurs when the bar 20 races on the opening stop 25, which affects lifting tongue 19 of the gripper with a mating support surface 21 a. The printed products released from the gripper 18 are retracted by a withdrawal conveyor 28.
    Within the assigned stepped formation, the printed products 4 also have a mutual distance a (distance between the steps), which is defined by the distance between successive grippers 18. This distance a is greater than the distance a between those located near the removal wheel 6 the upstream ends 4a of successively printed products 4 (Fig. 1). The grippers 18, circled around the reversing wheels 10 and 12, force the printed products 4, which provides the printed products with a grip on its rear edges 4b while it is still with its front edges 4a at the removal wheel 6. Thus, the printed product 4 is finally introduced into the grippers 18 before they are closed. Thus, print production 4 to her
    The grip of the grippers 18 cannot change its position, or it can change it to a very small extent, which makes it possible to maintain a uniform distance between the steps.
    5 If the reference surface, defined by both chains 8 and 9 and the supporting sheet 26 lying between them, has a smaller width than printed matter 4, then between the printed product 4 accelerated
    0 downward by the accelerating device 30 and this support surface, no air cushion can be formed which would prevent the rear edge 4c from being introduced into the action zone.
    5 grip 18. In addition, the printed product 4, when it enters the chains 8 and 9, is bent in the shape of a gable roof, which contributes to its stability.
    In case the printed design
    0 machine provides printed products 4 falling into the compartment 2. the correct position, i.e. with its front edge 4a, the production is completely adjacent to the bottom 2a of the compartments 2,, the alignment unit 39 can be refused. For known applications, the possibility of abandoning the accelerating unit 30, which serves to keep the rear ends of the printed products 4 in the course of movement 4 under all operating conditions, i.e. both at low and at high operating speeds, it was possible to reliably enter the zone of action of the grippers 18.
    5 In Figures 4 and 5, an embodiment of the device is shown, which is bypassed without the accelerating unit 30 and without the equalizing unit 39 (for the corresponding structural details in Figs. 1 and 5,
    0 the same designations). The principle of operation of the device shown in figure 5 corresponds otherwise to the same for the device shown in figure 1-4.
    The drive of circuits 8 and 9 from the inlet manifold 1 through the drive connections 16, 16, 17 gives a rigid connection between the rotational movement of the pen sender 1 and the circulating motion of the grippers 19, therefore no special clock and phase control is required or clock or phase correction during work. However, it is possible to allow the drive of the chains 8 and 9 not from the pen rykladyvatel 1, but by means of a separate drive unit.
    Opening the grippers 18 while changing the direction of the chains 8 and 9 by changing the direction of the wheels 10 to 13 gives a particularly simple and spatially compact design, since in addition to the direction-changing wheels 10 to 13 it is not necessary to provide any opening cams that open the wings or like them, which require an appropriate place, but it is possible to open the grippers 18 using such additional opening elements.
