    Two stop or impact members which are situated opposite one another with respect to grippers of a conveyor device are used for detaching or removing the printed products out of their product formation. In their effective position these stop members project into the conveying path of the printed products. The printed products released by the grippers impact against the stop members and under the action of their own weight drop downwards. Viewed in the conveying direction the printed products are folded or bent into a substantially saddle-like configuration forwardly of the stop members, resulting in stiffening of the thus folded printed products, and after they impact against the stop members they can fall downwardly along a straight path. In order to appropriately kink or bend the printed products there is provided a substantially saddle-shaped support upon which come to bear the printed products at the region of their trailing edge, these printed products being retained approximately at their central region by the grippers at their leading edge. The printed products also can be released from the conveyed product formation or stream along a very short path even when the conveyor device is operating at high conveying speeds.

    The invention relates to devices for sampling flexible flat products from a stream of transported material, in particular, printed products, and can be used in the printing industry.
    The purpose of the invention is to improve the reliability of the device by providing a sample of products in a short segment of transportation.
    FIG. Figure I shows the device with the tool for opening the grips turned off and the stops are shown; in fig. 2 shows a device with an included means for opening the grippers and inserted into the transport zone; in fig. 3 is a section A-A in FIG. I or 2; in fig. 4 shows a device with the gripper opener turned on and a toothed belt as an abutment; in fig. 5 is the same with the gripper opening included.
    Flow sampler
    The transportable flexible flat products, mainly printed products, contain a conveyor with grippers 2, reinforced with an interval on the traction body of the conveyor 1, a receiving shaft 3 and at least one driving means for opening the grips 2 as they pass, connected with the control body 4. In addition, the device contains at least one stop 6 installed in front of the means for opening the grippers during transport of the products, driving it to the transport zone and from it, the distribution a valve 7 connected with the control body 4, and a supporting surface 8 located in front of the stop 6 in the course of transporting the products, for bending the products 5,
    . Bearing surface 8 may be made in the form of a gable roof (FIG. 1-3) or a rod (not shown) or a gable roof additionally equipped with a rod-like support element 9 (FIG. 3), the working part of which is located at the level of the gable roof fold line. o The bearing surface 8 in the part facing the stop element has a bevel 10 (Figs. 1 and 2) o In front of the stop 6 in the direction of movement of the conveyor products 5 there is a guide element 11 for products 5. The receiving shaft 3 is located behind the bearing
    32
    overhead 8 in the course of transporting products 5 under the support 6.
    The device can be equipped with an additional stop 12 mounted opposite the stop 6, with the grab 2 of the conveyor positioned between the stops 6 and i 2.
    The drive of the lugs 6 and 12 and the means for opening the grippers 2 can be hydraulic or pneumatic, the control valves of which 7 and 13 respectively are connected. governing body 4.
    The device works as follows.
    Each pickup 2 of the conveyor 1 has a fixed clamping clip 14 and a movable breech clamp 15, which interacts with it. In the closed position: pickups: 2 hold the printed products 5, catching the tabs 14 and 15 with the leading edge (fold edge). The movable clamp: snail latch 15 is fixed in the closed: position with the help of the clamp 16. Opening of the claws 2 is performed by means of: from the grips of the grips, which is located on the holder 17 fixed on the traction body of the conveyor 1. element 18 which can
    raised and lowered by means of a pneumatic actuator 19, the actuator 19 has a distribution clalan 13, which is connected to an air inlet (not shown). The valve 13 is connected with the governing body 4. In its lower end position (in FIG. 3) the governing element 18 does not act
    clamps 16, so the passing grippers do not open (Fig. 1). EC

    in the extreme upper position, it acts on the anchors 16 of the grips 2, as a result of which the movable tongues 15 and 15 are released and rotated to the open position. In this case, the printed products are released, as shown in FIG. 2
    Each of the stops 6 to 12 has pneumatic or hydraulic actuators, respectively, 20 and 21. With the help of actuators 20 and 21, the stops: 6 and 12 move along their longitudinal axis, i.e. along arrow C. Drives 20 and 21 are connected to a control valve 7, which is on the transport body 1 and so31
    It is united with the control unit 4. In addition, the valve 7 is connected to a compressed air source (not shown). In FIG. 1 and 3, the stops 6 and 12 are shown in an extended position in which they are outside the zone of transportation of printed products 5. FIG. 2, stops 6 and 12 are shown in that position when they enter the transport zone. This position in FIG. shown by the dotted line.
    On the underside of the conveyor organ 1, there is a switch 22 of known construction, which, when passing each gripper 2, forms a tact pulse that enters the control unit 4. The pulses formed by the switch 22 determine the control cycle.
    In addition, on the traction body of the conveyor 1 there is a counter .23 also having a known construction. The counter 23 is provided with a finger 24 protruding into the transportation zone of printed products 5, which is influenced by the leading edges of the passing printed products 5, and with each influence a counting pulse is also generated that enters the control body 4,
    In front of each stop 6 and 2, in the direction of transport arrow A, guide elements 11 are mounted, which cover and protect the corresponding stop -6 or 12 in its withdrawn position from contact with printed products 5,
    Under the stops 6 and 12 there is a receiving shaft 3, which is formed by walls 25. To prevent damage to printed products 5, walls 25 in the area of the upper corners are bent. The shaft 3 at the bottom is covered by a receiving table 26, which can be raised and lowered.
    The device works as follows.
    As shown in FIG. 1-3, the printed products 5 are held by the grippers 2 approximately in the center of the leading edge. As soon as the rear edge is on the rod-like support element 9, the printed products are bent in the transport direction A. Thus, the printed products 5 receive the form of a gable roof. Then, the articles 5 arrive at the bearing surface 8, thanks to 6) 34
    They are shaped like a gable roof. In the case of bending, stiffness of printed products 5 is provided. This stiffness is of great importance for the sampling process.
    When the means for opening the grippers are in the disconnected state, the control element 18 is in the lower neutral position in which it does not act on the clips 16 of the grips 2. At the same time, the stops 6 and 12 are completely retracted and are outside the transportation zone of printed products 5. Grips 2 passes by means of their opening and moves products 5 under stops 6 and 12 past mine 3 (Fig. 1),
    If it is necessary to select printed products 5 from the staged flow with their laying in the shaft 3, it is necessary to turn on the means for opening the gripper and the stops 6, 12 enter the transport zone. On the Sampling command, the control body 4 generates synchronized control commands for the valves 13 and 7 on the basis of the clock pulses from the switch 27, taking into account that the means for opening the grippers (as viewed in the direction of transport A) is located at some distance behind the stops 6 and 12. Due to the commands from the control body 4, the valves 13 and 7 are switched, as a result of which the control element 18 of the means for opening the grippers is moved to the upper position in which they are in the transport zone Hovhan (Figure 2). Thanks to the control body 4, it is ensured that the means for opening the grippers 2 are inserted and the lugs 6 and 12 are inserted into the flow of transported products simultaneously. I.
    Tool for opening grippers
    in the manner described, the passing grips 2 are opened. As a result, the printed products are released and hit their leading edges on the stops 6 and 12. At the moment of the impact of the product 5 they are not on the supporting surface 8, but still retain their sharp form. As shown in FIG. 2, the bouncing of the products 5 that hit the stops 6 and 12 is prevented by the fact that the products, with their back edges, abut against the beveled edges 10 of the support surface 8. The released products 5
    5, i3
    fall under its own weight into the shaft 3 and fall on the receiving table 26 or on the printed products that already exist there. The roof-shaped shape of the products 5 stabilizes their movement during the free fall into the shaft. This is particularly preferable for thin products that tend to make swing movements during the free fall. Due to this stabilization of the fall of products 5, the latter fall linearly. This ensures that the products 5 lie flat on each other in the foot. Special measures for leveling off the foot are minimized or not required at all.
    In addition, additionally, the shape of the products 5 has other advantages. In terms of the product 5, they occupy a smaller area than in a flat position. Due to this, the products released from the grippers 5 freely pass between the walls 25 of the shaft 3. During the fall, both halves of the product 5, bent and initially forming an angle with each other, are straightened again in the plane. In this case, the products 5 contact with CTeHKasvfii 25 with their edges, due to which orientation and alignment of products 5 occurs. Regardless of the thickness of products 5, a flawless even foot 27 is formed.
    The counter 23 at each passing unit of product 5 generates a counting pulse, which is fed to the counting device of the control unit 4. The required number of products in the foot is set in this counting device. Counting pulses cause counting in the counting device. When the latter reaches O, then in the control body 4, commands are formed that switch the valve: we are 13 and 7. The means for opening the grippers 2 is switched, and the stops b and .12 are again moved upwards from the transport zone. The grippers 2 with the products 5 again pass by the shaft 3, which can now be released in a known manner.
    Due to the bending of printed products in the direction A of transporting, before contact with stops 6 and 12, stiffness is provided, and the resulting roof-like form contributes to the fact that after
    36
    Bearings printed products fall under their own weight into shaft 3 in a substantially straight line. Thus, sampling of products 5 is carried out in
    the place of their release from the grips 2.
    In this device, for example, the role of the stop may be performed by the tape 28 with the teeth 29s supported by the guide rollers 30 and 31, the last
    of which is installed at the free end of the swinging arm 32 (Fig. 4 and 5).
    In addition, the device can be equipped with a support roller 33 adjacent to the support, surface 8 and mounted for rotation between the shaft 3 and the support surface 8.
    You can also use another well-known conveyor, each grip 2 of which can hold two or more printed products 5.
    It is also possible to envisage several sampling positions of the printed articles 5, which are located in the transport direction A 1. 1 Friend after friend. At each such position of the sample, a means for opening the grippers and stops 6 and
    12 .. Since the sample of printed products is produced in a very short segment of the flow being transported, the positions of the sample of the product can be positioned close to each other.
    The printed articles 5 selected from the step flow need not be stacked. For example, the extracted printed products 5 instead of the receiving table 26 may fall on the conveyor, which is located under the shaft formed by the walls 25.
    Printed products, due to bending, acquire rigidity, therefore, using the proposed device, it is possible to work with thin products and with separate sheets, since such rigidity of thin products prevents deformation when colliding with
    stops 6 and 12,
    Thus, the proposed device is suitable for sampling from the transported stream not only printed PREDUCHSCH-; NA AND OTHER FLEXIBLE TO
