    The system deposits sheets in the fly sheet deliverer of a printing press. On initial braking of the positively-guided sheets trailing edge, the sheet is subjected a linear air jet controlled by a timer, extending over its entire width and acting downwards on it. This distorts it at right angles to the travel direction into a shape convex towards the sheet stack. As the sheet nears the stack, it is released by the chain grips, and a further air jet, also acting from above but in the travel direction, moves in a line from the centre outwards. This distorts the sheet into a shape convex towards the stack but in the lengthwise direction, as it is set down on the latter.

    (54) METHOD AND DEVICE FOR ACCELERATED ACCEPTANCE OF SHEETED MATERIALS
    one
    The invention relates to a method and apparatus for accelerated acceptance of sheet-shaped, deforming materials influenced by air, for example sheets, in sheet processing devices, in particular printing machines.
    A device (non-accepted application of the Federal Republic of Germany 1536989) is known for receiving sheets. By means of the device, the ejected sheet is driven by a carriage with grips on a web having an inclination to the slipway, so that the leading edge lies below the trailing edge. In this way of management, a wedge-shaped airbag arises between the sheet and the building berth, preferably moving in one direction. In order to keep air in the air, the sheet is loaded by air shchaber, rotating against the direction of movement by means of an air flow, squeezing the air bag back.
    A disadvantage of this device is that the rear edge has a large fall height, so that the sheet requires a long fall time and, in addition, there is a danger of the sheet being touched by the next carriage with grippers. In addition, the height of the stocks due to the inclination of the carriage web with grippers is so low that you often have to replace the stocks.
    A device is known (patent GDR 111870, in which the sheet is loaded from above on the entire surface 5. The air jet is both adjustable in steps and unregulated, the air jet can load the sheet in each zone evenly strongly or the sheet is deliberately formed simultaneously displaced or quantitatively different blowing streams in such a way that a part of the sheet is subordinate to the longitudinal axis of the sheet, and it has the shortest distance from the stocks.
    The drawback of the device is that at the beginning of the air influence the sheet has a large initial drop height, causing a large static volume of air under the sheet, which negatively affects the accelerated acceptance of the sheet. In addition, there is a danger of bending up the corners of the sheet.
    The purpose of the invention is the possibility of accurate output of sheet-like materials even at high speeds, namely the creation of a method and device for the withdrawal of sheet-like materials in order to be able to accelerate the loading of the sheet in the leaf-removing devices, while retaining simple non-curved carpets with grippers and high height of the stocks due to the low height ( (arc cushion pillow. The goal is achieved by the fact that the hatching process takes place in two successive phases, of which each is determined by the characteristic sheet deformation associated with responsible aerohydrodynamic effect.At the same time, the forced sheet is loaded in cycles by adjustable flow of air jets, moving together with the sheet feeding speed acting transversely in the sheet feeding direction throughout the sheet width linearly on top of the sheet, deforming transverse to the sheet feeding direction convexly to the stocks and approaching to the receiving slipway, is released by chain grips and then loaded by a stream of air jets from above along the sheet feeding direction, starting The c from the center line of the sheet, varying in time and / or quantity, which passes linearly outwards, is convexly deformed relative to the receiving stocks in the longitudinal direction, is drawn out and leveled. This method is made at the expense of the device by the fact that in front of the receiving stocks there are suction roller and above the receiving stocks and the carriage web with grips in the receiving zone of the sheets transversely and longitudinally the sheet feeding adjustable and controlled transverse and longitudinal pipes with outlet openings and connected to the air supply vessel. The air supply vessels of the transverse blowing pipes are made in the form of distribution vessels and the air supply vessels of the longitudinal blowing pipes are made in the form of a distribution pipe. The invention improves output performance and reliability, improves the quality of the edges of the stocks and thus further processability of the stocks, and the output sheet is pressed more carefully than with other methods on the stocks. FIG. 1 shows a sheet-waving device with a sheet being withdrawn during the first phase of acceptance, side view; in fig. 2 - leaf-dispensing device with an output s. Sheet during the second phase of acceptance, front view. FIG. 1 is a side view of sheet 1 during its continuous supply through the receiving stack 2 in the first acceptance phase, which begins with the rear end of the sheet 1 being tensioned. Sheet 1 is led in this acceptance phase at the leading edge along the carriage web with grippers 10 and is loaded transversely to the feed direction of the sheet 12 in a linear manner over the entire width of the sheet from above by air jets in this way. That the sheet 1 is in place, loaded with air jets, is deformed convexly relative to the receiving stocks 2. The stream of air jets jointly moves with the sheet feeding speed. In this case, sheet 1 is loaded at the same place and deformed (see Fig. 1). The type and parameters of the deformation of sheet 1 depend on the intensity of the controlled and controlled stream of air jets. Between the sheet and the receiving stack 2, a reduced pressure occurs simultaneously due to the relative speed between sheet 1 and the ambient air so that sheet 1 at the time of the end of the first phase of acceptance (release of sheet 1 by chain grips 4 to shut off the air stream) is already close to the receiving slip 2. 2. FIG. 2 shows in front view the sheet 1 in the second phase. The material is immediately following the first phase of acceptance. In this phase, the sheet 1, which lies at the front stops 9, is loaded, starting in the middle of the sheet and continuing to the extreme zones from above along the entire length with jets of air. The stream of air jets presses sheet 1 onto the slipway of receiving 2, and sheet 1 is deformed convexly relative to receiving slip 2 in the longitudinal direction, i.e. the sheet first lies coaxially with the longitudinal axis on receiving slip 2 and is smoothed from inside to outside under the influence of the jet flow air, and at the same time it is leveled at the front stops 9. The stream of air jets is adjustable so that it can be larger in the section of the longitudinal axis and diminishing to the outermost zone. With the flat position of the sheet 1 on the receiving stack 2, the alignment of the sheet 1 and the shutdown of the air jet, in the reverse order controlled as on, the acceptance process ends. The device consists of transverse and longitudinal blowing pipes 5 and 6 connected to air distribution vessels 7 and 8. Air distribution vessel 7 and 8 for transverse blowing pipes 5 is designed as a distribution vessel 8 and for longitudinal blowing pipes 6 - as a distribution pipe 7. Transverse and longitudinal blowing tubes 5 and 6, in some of them lying at an angle of 90 ° to each other, are located above the receiving berth 2 and the carriage web with the grippers 10 and are equipped with outlet openings 11. The outlet openings 11 of transverse blowing pipes The bottom 5 is vertically directed to the reception slipway 2, the outlet openings 11 of the longitudinal flow tubes 6 from the inside to the outside have an increased skew. Air generators (compressors) for supplying blast air to air distribution vessels 7 and 8 are not shown. Preferably, higher flow and low pressure compressors are used. The transverse and longitudinal blowing pipes 5 and 6 can, as shown, be connected to one air distribution vessel 7 and 8, respectively. It is also possible to provide for only one central distribution vessel 7 and 8. Instead of the transverse and longitudinal blast tubes 5 and 6, it is also possible, with central air supply, to also place a blower box and cross-shaped nozzle rows above the receiving slipway 2.
    Outlet openings 11 have closing elements (not shown) for adjusting the flow of air jets.
    In a known manner, chain clamps 4, which are led on the carriage web with grippers 10, are located in the withdrawal device. In front of the receiving slipway 2, viewed in the sheet feeding direction, a braking member is provided, implemented as a suction roller. Instead of a suction roller, suction pads or other devices that pull the device’s rear edge are also available. On the stocks receiving 2 provided by the front stops 9.
    The principle of operation of the device is as follows.
    The chain grippers 4, moving along the carriage web with the grippers 10, the sheet is continuously passed through the slipway when I am 2. At this, sheet 1 enters the zone of the suction roller 3 and sticks. At the same time out of the outlet openings 11 of the transverse blower pipe 5.1 air stream.
    In the further passage of the withdrawal process, the outlet openings -11 of the transverse blower pipe 5.1 are closed and the outlet openings 11 of the transverse blower pipe 5.2 open.
    In a similar order, the outlet openings 11 of the transverse blower pipes 5.2 to 5.5 open and close.
    The release of the sheet 1 due to the chain grippers 4 closes the outlet openings 11 of the transverse blower pipe 5.5. At the same time, the outlet openings 11 of the longitudinal blowing tubes 6 are opened, starting from the longitudinal blowing tube 6, located in the middle of the diet, in time order and continuing with the external longitudinal blowing tubes 6. It is also possible to open all the discharge openings 1I simultaneously and at the same time operate medium longitudinal blow tubes with a higher intensity air stream. All outlets 11, which are subordinate to a single longitudinal blowing tube 6, open simultaneously. Closing the weekend
    The opening 11 at the end of the withdrawal process is performed in reverse order as an opening, i.e., from the outside to the inside. The air supply of the longitudinal blast tubes 6 occurs through the distributor tube 7. The method is also realized when, instead of the transverse and longitudinal blast tubes 5 and 6, there is a nozzle scoreboard with crosswise controlled and adjustable nozzle rows above the receiving slide 2.
