    (54) METHOD FOR FILING SHEETS INTO THE PRINTING MACHINE
    one
    The invention relates to equipment for printed products and can be used in sheet-fed printing machines, in which the sheets, after their separation from the foot, are fed to the leveling bodies on the overlay table in the form of a cascade flow.
    The closest to the invention to the technical essence and the achieved result is a method of feeding sheets into a printing machine, which includes feeding sheets in a cascade flow on the application table, transporting sheets on the application table, aligning each sheet along the front and side edges and sheet feeding into the paper. In this method, an alignable sheet before or during its supply to the machine is positioned in the lateral direction by means of a suction tire or a gripping device, as a result of which the side edge of the sheet to be aligned is released for lateral alignment 1.
    The disadvantage of this method is that the lateral alignment should be windows; Until the front edge of the next sheet does not reach the zone of action of the lateral pressure device. Therefore, for the front and side alignment of the sheet, the time determined by the moment of reaching the sheet to be aligned to the front stops and the moment of reaching the next sheet of the side alignment device is intended, which leads to insufficient accuracy of sheet alignment.
    The aim of the invention is to increase
    10 precision sheet alignment by aligning the sheet to be equal, regardless of the already aligned and subsequent.
    This goal is achieved by the fact that when transporting sheets on an invoice table, the sheet to be leveled is mixed aside parallel to itself before its leveling begins on the side edge.
    FIG. 1 shows a cascade flow of sheets, side view; in fig. 2a lateral displacement of the sheet in the first phase; in fig. 26 - side shift in the second phase; in fig. 3 - lateral alignment; in fig. 4 - sheet feeding into the machine with lateral displacement in the direction opposite to the lateral alignment; in fig. 5 - lateral displacement, option; in fig. 6 shows the suction band shown in FIG. 2, side view; in fig. 7 - sheet feeding into the machine, option; in fig. 8 - side-mounted pneumatic tire, side view; in fig. 9-mechanical side view, side view.
    The method according to the invention is characterized by the following steps: the lateral displacement of the front sheet, which is closest to the leveling means of the sheet G, from the cascade flow of sheets 1, 2, 3; automatic alignment of the leading edge and alignment of the side edge due to lateral displacement of the sheet; feeding the leveled sheet into the machine in case of preliminary and / or simultaneous lateral displacement of the sheet in the direction opposite to the direction of alignment, by the same amount.
    FIG. 1 shows a cascade flow of sheets 1-3 located on an overhead table 4. FIG. 2a, the sheet 1 to be leveled is offset from the flow. FIG. 26 - lateral displacement of sheet 1 is completed. The sheet 1 lies against the front edge of the front stops 5, and its side edge is in the area of action 6 of the side-leveling device. Other sheets are still in the cascade stream. FIG. 3 — sheet 1 to be aligned is aligned with the front and side edges, while the next sheet 2 is offset away from the sheet flow. The lateral displacement and alignment of the sheets are carried out partially in parallel. FIG. 4 - leveled sheet 1 is already fed into the machine. Simultaneously with the feed it is shifted to the side in the direction opposite to the side alignment. FIG. 5 shows another variant of lateral displacement. The latter is carried out only after the sheet reaches the front stops.
    The proposed method is implemented using a device consisting of suction tapes 7 with vacuum suction means 8 and holes 9 located below the surface stbl 4 at an angle of 6 in the direction of sheet displacement, front stops 5, leg 3, side alignment II and rollers with brushes 12 mounted on an overlay table 4 having separate drives and adjustable from the rear edge of the sheet.
    As shown in FIG. 6, on the suction tapes 7 there are catching hooks 13 which rotate together with the tape. FIG. 5, the suction band 7 is set across the sheet feeding direction. With such arrangements of the tape 7, it does not have hooks 13. The feeding device providing lateral displacement of the leveled sheet in the direction opposite to the side alignment is not shown. For
    This can be used by the forwarder 14, suction tires or similar devices.
    Sheet feeding can be performed in another embodiment, which is characterized by
    the following stages: the lateral displacement of the front, closest to the leveling means of the sheet 1 of the cascade flow; automatic front edge leveling and side leveling
    0 edges due to lateral displacement of the sheet; feeding the leveled sheet into the machine without lateral displacement.
    According to this variant of leveling and feeding sheets into the machine, sheet 1 to be leveled as it is so far:
    FIG. 2a and 26 are shifted out of the flow and aligned {FIG. 3). After that, the leveled sheet 1 is fed into the machine (FIG. 7). In this case, the sheet does not move laterally.
    This variant of sheet feeding is realized with the help of a device consisting of a suction belt 7, front stops 5, side stops 10, a side-alignment device 11. rollers with brushes 12, and a free-rider 14.
    5 The principle of operation of the devices used is as follows.
    The cascade-like flow of sheets 1-3 enters the zone of action of the belt 7 rotating at a variable speed, and the sheet 1 is preliminarily aligned. When sheet 1 collides with the hooks 13, the belt 7 has a speed which is approximately equal to the flow velocity. Thereafter, the tape 7 decreases its speed, the sheet 1 is braked and moves with
    5 with a lower speed to the front stops 5 in the direction of the zone of action 6 of the device of lateral balance 11. At the front stops 5, sheet 1 is aligned with its front edge. By capturing the sheet by the device 11 in zone 6, the sheet 1 is moved aside to the side stops 10 and aligned along its side edge.
    In order to ensure a constant fit of the sheet 1 to the front stops 5, rollers with brushes 12 act on the rear edge of sheet 1. as a result, the side edge of the next sheet 2, which is in the area of action 6 of the side alignment device I, is released. The lateral displacement of the sheet 2 and the lateral return movement of the sheet 1 are carried out simultaneously before or during the cutting of the sheet 1 into the machine.
    According to another embodiment of sheet feeding, sheet 1 is shifted to the side of the flow and aligned. Thereafter, the leveled sheet 1 is fed to the machine without lateral displacement. The device of lateral equilibrium in this embodiment is shown in FIGS. 8 and 9. In FIG. 8 shows the pneumatic device 16; FIG. 9 - mechanical. The latter consists of a roller 17, located below the overlay table 4, and of a bias 18. The roller 17 moves vertically towards the table 4. The tire 18 moves along the trajectory 19 and rotates synchronously with the movement of the sheets in their plane. In this case, the sliding sheet, 1, is raised with the aid of a strip 18, and the side edge of the sheet 2 to be aligned is pressed by the roller 17 to the bar 18 and can be pressed against the side stops 10 and thus the sheet is aligned in the lateral direction. The proposed sheet feeding method allows for increased accuracy in sheet alignment. The feeding of the leveled sheet into the masking unit, by freeing the entire side edge of the sheet to be leveled, which is located in the zone of action of the side alignment device, makes it possible to align the sheet independently of the previous and subsequent sheets. The area of operation of the device of lateral equilibrium can be located at any distance relative to the line of transmission, therefore

    The side of the side alignment device can be determined by the center of the sheet surface, and when processing heavy paper, lateral movement can be carried out in two or more areas of action, and therefore hard sheets can be fed in the same way.
