    Arrangements for feeding out sheets to stacking magazines in general feed out sheets one at a time at the upper end of the magazine, where they fall freely downwards and together form a stack. The comparatively low rate of fall of the sheets limits the working speed, and in order to increase the working speed and functional reliability an arrangement is proposed in accordance with the invention, wherein the sheets (6) are fed out from a carriage (2) which is lifted in timed relation with the growth of the stack of sheets so that the sheets are fed out the whole time directly to the top end of the stack.

    The invention relates to equipment for feeding sheets or blanks to a stacking stack.
    The aim of the invention is to simplify the design and increase the reliability of sheet feeding to the drive.
    Figure 1 and 2 shows the device, side view.
    The device comprises a guide 1, which is fixedly attached to the frame of the machine (not shown) and is positioned vertically or at a certain angle, for example at an angle of 30 °, relative to the vertical plane. The carriage 2 can move along the guide 1 and its movement is adjusted by several guide rollers 3, which are mounted so that they can freely rotate in the carriage 2 and roll along the groove 4 in the guide. Next to the guide 1, there is a stacking stack 5, which is constructed so that it receives individual sheets or blanks 6, forming a stack, which is located mainly in parallel along the guide 1.
    Both ends of guide 1 have deflecting pulleys 7 and 8, with the lower
    The pulley 8 is mounted in this way, which mounts freely to rotate in guide 1, and the upper pulley 7 is connected to a drive motor (not shown). Between the twin deflecting pulleys 7 and 8, the endless drive belt 9 performs a dual function: moving the carriage 2 along guide 1 and transferring the sheets or blanks 6 from the feed position (not shown) located at the upper end of the guide 1, to the carriage 2. Thereafter, the sheets or blanks 6 are fed to the hopper 5 via the second belt 10, i.e. outstanding belt.
    Each of the two belts 9 and 10 can have the form of a relatively wide endless belt whose width corresponds to the width of the sheets to be transported to the stacking drive 5. You can replace the relatively wide belt 9 or Yun with several narrow belts that can even have a circular cross-section. Such belts can be passed through cylindrical rollers or individual pulleys mounted on a common axis. Active, used for the transportation of sheets part of the drive REMn 9
    extends directly and freely from the upper deflecting pulley 7 to the lower deflecting pulley 8. The return part of the drive belt 9, which is used to move the carriage 2 upwards along the guide 1, passes through the tension roller 11 installed in the guide 1 p a house with a lower deflecting pulley 8, a tension roller 12 that can rotate freely in the carriage 2, and a pulley 13 mounted rotatably on the carriage 2, and back to the upper driven deflecting pulley 7. Two tension rollers 11 and 12 that can be a known way spring-elasticity for retaining the drive belt 9 in the tensioned state, directed drive belt 9 so that it surrounds part of the pulley 13 and retained with it in constant drive interaction.
    The pulley 13 is mounted on an axis that can freely rotate in the carriage 2. Gear 14 is fixed at the opposite end of the axis. Gear 14 interacts and is in constant engagement with the identical gear 15, which is fixed on the axis, rotates freely in the carriage 2 and at its opposite end a pulley 16 is installed, having the same diameter as the pulley 13, interacts and is driven from the discharging belt 10 in such a direction that its active part, located next to the active part of the driving belt 9, moves quickly down to accumulate Any 5. Along the active part of the issuing belt 10, a guide rail 17 passes, having a curved shape and extending downward with a gradual increase in the angle towards the guide 1. There are two deflecting pulleys 18 and 19 at the upper end of the guide rail 17, through which the active part of the belt 10 passes to the pulley 20, which acts as a deflecting pulley. The issuing belt 10 is directed mainly upwards by a tension pulley of the belt 21, which is adjusted in the usual manner, and back to the driving pulley 16.
    Below the pulley 20, there is an ejection roller 22, the ejection belt 10 extends between the pulley 20 and the ejection roller 22, the central axes of which are at such a distance from each other that the free distance between the belt and emitting roller in the unloaded condition of the device is somewhat smaller, than the thickness of one sheet to be submitted. Preferably, said free distance is 0.3-0.8 sheet thickness. As a result of practical experiments
    it is determined that this distance may well be half the thickness of the sheet.
    The mouth 22 is set so that the distance
    between it and the belt 10, in the unloaded condition, somewhat increases under the influence of a certain force. This is achieved by making the pulley 20. the dispensing roller 22 or one and the other.
    from elastic material, for example rubber. The desired elasticity can also be achieved by equipping the pulley or the delivery roller 22 with movably fixed axles, which are acted upon by
    spring means, clamping their qpyr to a friend.
    On the other side of the card, facing the stacking drive 5, there is a supporting 23, which passes
    at an angle downwards The front end of this lever is made of flexible material, such as spring steel. In addition, the lower part of the carriage 2 is equipped with a storage wall 24, which is fixed
    attached to the carriage 2 and forms together; there is a movable wall in the stacking storage 5. The said wall is coordinated in time with the carriage 2 and ensures that the sheets 6 supplied to the stacking storage 5 are always on a flat surface.
    Ppi. the operation of the feeder of the proposed device, sheets 6 are fed in the upper part of the guide 1 by means of the usual
    feeder (not shown). This device places, one after the other, sheets 6 -ia of the active part of the drive belt 9, the spine on the part of this belt moving downwards, which faces the drive 5. The drive belt S can be wielded by shelves arranged through the open spaces that support sheets placed on the active part of the drive belt 9 and hold
    they are in the right position when moving down. In addition, you can install another endless belt (the additional belt is not shown) by placing it in front of the active part of the drive belt 9 such
    such that the fed sheets are held between the two said belts.
    The A1 part of the driving belt 9 is moved by the driving pulley 7 at a predetermined speed to the lower deflecting pulley 8, the sheet located on the driving belt yawning until the rail 17 reaches the upper edge of the carriage 2.
    The guide rail 17 grips the sheet and removes it from the drive belt 9 so as to guide it between the guide rail 17 and the active part of the dispensing belt 10, which is more and more approaching the upper somewhat curved sliding surface in the direction of the stacking drive 5 rail 17.
    The issuing belt 10 is driven through two gears 15 and 14 and the pulley 13 by the rear or upwardly moving part of the drive belt 9, which, under the influence of the tension roller 12, must be pressed against the pulley 13 and rotate it. Using the active part of the discharging belt 10, the sheet is further guided along the upper surface of the guide rail 17 until the front end of the sheet (as seen in the feed direction) falls between the pulley 20 and the dispensing roller 22 and as a result of the limited free space between them there will not be between the discharging belt 10 and the surface of the dispensing roller 22. Since the pulley 20, the dispensing roller 22, or both, are made of an elastic material, as the resistance increases, the sheets move further between the pulley 20 and the discharging material m 22 angled downward at the supporting arm 23 at the top to accommodate pg; hibernation sheets in the accumulator 5, the pressing Referring to the wall 24 of the accumulator. Increasing the resistance when the sheets pass between the pulley 20 and the emitter roller 22 implies that the movement of the emitting belt 10 is opposed, and as a result, the tension on the belt decreases, i. pulley 16 is braked. The resistance is transmitted through two gears 14 and 15 from the pulley 13, as a result of which its rotation slows down and the part of the driving belt 9 moving upwards, adjacent to the periphery of the pulley 13, instead of simply rotating the pulley 13 through: the pulley slightly lifts the carriage 2 along the guide 1. In the process, the pulley 13 and the gear 14 act as a lever, one arm of which is formed with a diameter between the point of action of the drive belt 9 at the periphery of the pulley 13 and the point of interaction of the gear 14 with the inhibited gear 15, and the other It is formed by a radius between the common center of the axles of the pulley 13 and gear 14 and the indicated point of interaction. As a result, the carriage 2 rises or moves to a short distance, the sheet is discharged and the carriages into the drive, which means that the support arm 23 simultaneously rises from its idle position on the top sheet of the stack of sheets and allows the new sheet to pass between the support arm and bundled sheets. how
    only the rear end of the incoming sheet (judging by the feed direction) leaves the space between the dispensing roller 22 and the pulley 20, the braking effect of the sheet on the pulley 16 ceases, resulting in
    0, the drive belt 9 can no longer lift the carriage 9 and it slides down a short distance along the guide 1 until the lower end of the support arm 23 is once again supported on the stack of sheets.
    5 Since the sheets are fed into the device continuously and at equal intervals, the carriage 2 rises a short distance along the guide 1 in coordination with the feeding of these sheets to the hopper 5, so that
    0 then retake its position, and the support arm 23 rests on the top sheet in the 5 stack of sheets in the storage unit. Since each sheet is actively fed from the initial position in the upper part of the guide 1 to the final position in the accumulator 5 all the time, the sheets are fed with great reliability even at high speed. Poi practical device test well
    0 zlgkomendovol se at such speeds as tsachi as 12C sheets p 1 mmn.
    The proposed ripe equipment is a value that is relatively narrow for submission: does res, but there is a possibility of naphmer,
    5, when feeding wide t: t roe, equip the device with double, mirror-facing lines and give Xfstke two identical, mirror-like ends, between which different axes with their rotating parts are located. The lifting of the carriage 2 when being fed between the pulley 20 and the dispensing roller 22 can be adjusted by changing the TIR-BONE of the dispensing roller 22 and the pulley 20 so that
    5 that the issuing belt 10, and, together with it, the pulley 16, is braked with more or less hh, this means that a greater or lesser part of the force of the driving belt 9 is tested for actual
    0 raising the carriage 2. Good results can be achieved when using a machine, in which the pulley 20 and the delivery roller 22 are mounted as follows. that can rotate freely around the axes that
    5 are adjustable, but remain fixed others / g relative to each other, with the pulley 20 being made of an elastic material, the dispensing roller 22 from a flexible rubber material. The design and arrangement of these parts can be varied and adapted to sheets of this type, actual feed rate and other requirements that exist in a particular situation.
