    The invention relates to equipment for feeding and storing sliced sheets of paper into the receiving section of paper cutting machines.
    The purpose of the invention is to increase the efficiency of the process by ensuring the safety of the sheet material at high speeds of work.
    FIG. Figure 1 shows schematically the retarding mechanism and the means for removing the sheet stack, side view; in fig. 2 shows an embodiment of the invention, side view; Fig.3-5 The second - the fourth versions of the retarding mechanism, partial side view.
    The method of accumulation of sheets passing in an intermittent flow into the package is that sheets 20 are fed into the accumulation zone at a speed lower than the speed of their transportation, and slowing down the speed of sheet transportation when fed to the accumulator is carried out by clamping erd 25 of the tail section.
    The device for accumulation of sheets passing in an intermittent flow into a bag contains successively installed high-speed belt ZO conveyor system 1, a decelerating mechanism having a decelerating roller 2 and a hopper 3. The decelerating mechanism is additionally provided with clamping and pushing means (embodiments of which will be discussed below) the tail of the sheet 4, located above the retarding roller 2, which is installed with the possibility of periodic free rotation. In the shown, Q nom in FIG. 1, the clamping and pushing means of the tail of the sheet is made in the form of a roller 5 with brushes 6.7. Both rollers 2 and 5 are driven in rotation in the opposite direction by the electric motor 8 through the gear 9.
    The retard roller 2 is rotated at a peripheral speed of about 76-107 m / min. The roller 5 has two diametrically opposed brushes 6.7, extending from it in the radial direction. When the sheets are fed by the conveyor 1, the front end of the sheets 4 passes between the rollers 2.5, when the brushes 6.7 are arranged approximately horizontally, which allows the front end to freely pass between these two rollers. With further sheet movement between
    1449008
    two rollers one of the brushes 6 or 7 comes into contact with a part of the sheet 4 near its tail end and presses the sheet 4 to the decelerating roller 2. After the retracting brush 6 or 7 moving away from the roller 2, there is nothing that would ensure the movement of the sheet 4 in the kipu of sheets 10 being collected in accumulator 3, therefore sheet 4 remains on roller 2, until brush 6.7 again comes up, bending the tail section of the next sheet. At the same time the brush 6,7 puts pressure on both sheets. As shown in Fig. 1, the brush 6 bends the tail of the sheet 4, while the previous sheet 11 is still in contact with the retard roller 2. As the brush puts pressure on both sheets, the bottom sheet 12 accelerates to approximately 45.7 7.6 m / min and enters the accumulator 3, as shown by the example of sheet 12. The upper sheet 4 remains on the decelerating roller 2, waiting for the next gripping by brush 6 or 7. In this way, the sheets are stacked in a pile 10 with low speed.
    Bale 10 accumulates more than one stack of paper, which provides the compaction needed to extrude all air from the bale 10. The feet are removed from the bottom of the bale, as shown in Fig. 1, where the foot 13 is removed. A separator in the form of a lance 14 is inserted into the bale 10 to separate the foot 13 having a pointed front end 15 to provide the initial entrance to the lance 14 at the bale 10 and provided with a tape 16. A pointed front end separates the top sheet 17 of the foot 13 from the bottom sheet of the 18-bale 10. The tape 16 on the lance 14 is supported at one end by means of the front roller 19, and at the other through the rear roller 20. When the spear is inserted into the bale 10 to separate the foot 13 from the rest of the bale tape 16 moves along the rollers 19, 20, as shown in Fig. 1, in a clockwise direction, with the result that any part of the tape that comes into contact with the bottom sheet 18 of the bale 10 remains stationary relative to it, until the spear will go completely into the pile.
    Down from the lance 14 moves the pusher 21, which comes into contact with the side surface of the foot 22
    13 and serves to move the foot sideways when the lance 14 is inserted into the pile 10. The ejector plate 21 has a height at least slightly greater than the thickness of the separated foot 13 to provide a gap 23 between the upper sheet 17 of the removed foot 13 and the tape 16 moving around the rollers 19 and 20.
    Bale 10 is typically supported by a lifting table containing two conveyors 24, 25 with freely rotating rollers in contact with the lower sheet 26 of the lower foot in the pile 10. The two conveyors 24,25 contain a split lifting table that allows the supports to be supported. the possibility of introducing the lance 14 into the pile 10 and removing it from there. Both conveyors 24, 25 are mounted with the possibility of independent vertical movement, which provides, if necessary, continuous support of the foot 13 and the bale 10.
    With the introduction of the lance 14 in the pile 10, the pusher 21 moves the foot 13, supported by conveyors 24, 25, towards the table 27 with air blowing. When the foot 13 is on the table 27, as shown by dotted lines, most of the paper weight is carried by an air cushion created by supplying pressurized air through the channels 28 in the table, opening onto the top surface 24 of the table through separate air holes 29. To move the individual stops 13 to the next section of the paper handling system, use longitudinal conveyor belts 30, 31 extending over the surface 24 of the table 27.
    When the lance 14 leaves the bale 10, the smaller conveyor 24 with freely rotating rollers is moved in the vertical direction to support the bale 10, while continuing to deduct the lance 14 from the bale. Immediately after removal, the lance is moved in the vertical direction and the second conveyor 25 also to support the bale.
    It is desirable that the top sheet (represented by the sheet 32 in Fig. 1) of the bale 10 remain at the same level with respect to the rollers 2.5 during the entire operation of stacking the sheets in the bale 10. Therefore, the spear 14,
    0
    and conveyors 24,25 are mounted with the possibility of vertical movement on the rod 33. In addition, as shown in FIG. 1, the accumulator 3 for bale 10 has a notch 34 corresponding to the entry point of the lance 14, whereby the lance 14 can be in contact with the bale 10, while still retained in the accumulator 3, and when the spear 14 is inserted into the bale 10, it will also move down due to stacking 10 additional sheets so that when 5 lance 14 reaches the opposite wall 35 of accumulator 3, it will pass under the lower edge 36 of this wall.
    FIG. 2 shows a variant of the separating device in which the pile 10, the spear 14, the conveyors 24.25 with freely rotating rollers and the air blowing table 27 are inclined at the same angle, which allows 5 to improve the process of laying the sheets and separating the folding 13. In contrast from the lower conveyor belts 30 and 31 in the embodiment shown in Fig. 1, the table 27 is provided with a side conveyor belt 37 driven by an electric motor 38 for moving the individual feet 13 to the next processing position. In all other respects, this option acts in the same way as the one shown in FIG. 1, it only uses gravity force to ease the leveling of the pile 10 and remove individual feet 13.
    FIG. 2, roller 5 is shown differently than in FIG. 1, the rotational position and it can be seen that the paper sheet 39 moved by the high-speed belt conveyor 1 passes between the rollers 2.5. It is also seen that the brush 7 will come into contact with the tail part of the sheet 39 and will press it against the roller 5, and the pressure of the brush 7 will accelerate the movement of the sheet 4 lying on the roller 5 and the movement of this sheet in the pile 10.
    FIG. 3 shows a variant of the device, according to which the individual sheets 40 to 43 are fed, as shown, into the building berth 44 by means of two high-speed belts 45, 46, which transport the sheets at a speed of up to 457.5 m / min. The lower belt 45 is supported at one end by means of a roller 47 and at the opposite end

    by the same roller (not shown), and the upper belt 46 is supported by the rollers 48, 49 and additional rollers (not shown). The upper belt 46 extends further to the right (as viewed in FIG. 3) behind the roller 47 supporting the lower belt 45.
    In the embodiment shown in FIG. 3, there is provided a clamping and pushing means for the tail of the sheets, which contains a retarding vacuum roller 50 and a nozzle 31 for directing the sheets with an air jet to the retarding roller 50. The vacuum roller 50 is rotated by means of an electric motor 52. To create a vacuum in the vacuum roller 50 and creating pressure in the internal cavity of the air nozzle 51, a schematically shown blower 53 is used. The vacuum roller 50 is hollow with a plurality of through holes 54 in its wall, and the vacuum with zdaval in its internal cavity by the blower 53, causes air suction radially inwardly through the openings 54. Due to the large number of holes 54 in the suction pressure roller 50 in any given hole 54 is relatively low.
    The retarding mechanism further comprises a cylindrical rotary body 55, which is horizontal and has a longitudinal slit 56 extending along its length, located in the lowermost part thereof. The housing 55 surrounds the nozzle 51 containing a hollow element with an elongated nozzle 57 whose central channel 58 passes radially outwards. The housing 55 is rotated around a horizontal axis by an electric motor (not shown), wherein the nozzle channel 58 is aligned with the slit 56 in the housing 55 one rae per revolution
    housing 55.
    The rotating body 55, in turn, is placed in an air box 59 having a slot 60, which can be aligned with the rotating slot 5 of the rotating body 55. Once every o6opof body 55, slots 56 and 60 will be aligned and the air stream will go down between the belt 46 and the tail of the paper sheet, causing the sheet to be pressed toward the retarding roller 50.

    rotation of the housing 55 from the cut off the air flow into the slot .60, when the front end of the spreading sheet of paper passes by this place.
    In the air box 59, there is a second horizontally above (downstream of the sheets) first slit 60 slit 61, which directs the air in the direction of motion and causes a Venturi effect between the paper to the air box 59, with the result that the front end of the sheet is pressed against the upper belt 46 Thus, the front end of the next sheet rises above the tail end of the previous sheet located
    over the pile 44.
    FIG. 4 shows another embodiment of the device, where it is shown how individual sheets 62.63 are fed into bale 64 by means of a high-speed belt 65, which transports the sheets at speeds up to 457.5 m / min. Len25 tu 65 is supported at one end by means of a roller 66 and at the opposite end by means of the same roller (not shown).
    In the embodiment shown in Fig. 4, the clamping and pushing means of the tail of the sheets comprises a swinging spring-loaded roller 67 driven by a signal determining the location of the sheet edge and the space between the spins to ensure its proper position on the tail
    sheet.
    The roller 67 is rotatably mounted at the end of a lever 6B pivoting around a fixed point 69. The lever 68 is continuously pressed down by means of springs 70 and selectively retracted upwards by means of an actuator 71, for example, a retracting piston.
    FIG. 4 shows a sensitive element of the location of a sheet edge in the form of an optical sensor 72 having light-emitting or light-reflecting means 73 directing light to the sensor 72 during the gap between the successive sheets of paper. The sensor 72 is connected to a control device 74, which controls a valve 75 connected to the piston 71. At appropriate times, the piston 71 is retracted, thereby raising the roller 67 to the position 76 shown in dotted lines. This allows the sheet to be moved past roller 67, He40.

    mediocrely before passing the tail 67 of the tail section of the sheet, the control device 74 cuts off the lifting means 71 and the spring 70 by moving the roll 67 downward, pressing the tail of the sheet to the retarding roller 50. At the same time, the speed of the sheet decreases and the sheet falls onto the slipway 64 of sheets .
    A slug roller 50 is driven into rotation by an electric motor 52, and it can be a vacuum roller with a plurality of through holes 5A distributed throughout it, a vacuum in which is created by means of a blower 53. The outer surface -77 of roller 50 is covered with rubber or a material with a high coefficient of three and that promotes adhesion of the vacuum roller to the sheets.
    FIG. Figure 5 shows a variant of the device, according to which it contains a support plate 78 located directly behind the roller 47 of the conveyor system in front of the retarding roller 50, which is, as shown, a vacuum roller. In this embodiment, each sheet is slowed down and passed into the pile 10 individually and immediately, without leaving, as shown in FIG. 1, on the retard roller 2 awaiting the next gripping with the brush 6
    The described invention allows to provide high quality products when the device is operated at higher speeds.
