    Grippers pull the leading ends of sheets along a sheet transport path, and a guidance structure facilitates sheet travel. The guidance structure comprises a plurality of longitudinally extending guide bars provided with suction openings, the ribs spaced apart transverse to the sheet-transport direction. Intermediate the bars are large-surface-area plates having suction openings. When guiding sheets printed on only one side, the intermediate suction plates are at about the same level as the longitudinally extending guide bars, and the entire face of the sheet is engaged, with the help of suction force. When guiding sheets printed on both sides, the imtermediate suction plates all drop down out of contact with the sheet, leaving only the spaced apart and narrow longitudinal guide bars to engage the sheet. The guide bars are furthermore transversely shiftable, so that they can be brought into engagement with parts of the sheets bearing no printing.

    专利说明:

    SHEETS are made in the form of brackets that are adjustable in the width of the machine, with pivoting suction boxes lying between them. The suction pads are made in the form of a four-hinged connecting rod. In the sheet feeding mechanism, it is possible to sequentially arrange several suction boxes connected to each other. To eliminate the bending of the printed sheet, a sheet straightener is connected in front of the sheet guiding device, which is driven by face print with suction air and rotates in the sheet direction. With face print and rotation printing. Sheet Aviation does not work. Sheet flattening is connected to the sheet guiding device and is switched to 4aetc. The combination of staples for guiding sheets that are at a constant distance to the transported sheets but which are adjustable in width, with spacing between the suction pads, ensures that the sheet is transported through the output transfer device with the front printing, and also with the front printing and Me about company. In face printing, the sheet is pulled across the entire surface towards the sheet guiding device. Sheet guide rods and / or suction boxes are pneumatically loaded. In the case of facial printing and rotation printing, the suction drawers are unscrewed, and only rods for guiding the sheets support the direction of the sheets. Fig. 1 shows a terminal output with a device for guiding the sheets, side view; Fig. 2 is a side view of the device for guiding sheets; in fig. 3 paiSpea A-A in FIG. 2 (in position 1 of the front seal); in fig. k is a section 8-B in FIG. 2 (in the position of facial printing and printing with a turn); FIG. 5 is a view of B in FIG. The sheet-and-tail device comprises a chain conveyor 1, in which, at a constant distance from each other, trolleys 2 with grippers 3 for sheets are located. In addition, the device includes chain-mounted impellers k, a receiving slipway 5, a suction roller 6, and a device for guiding the sheets. A device for guiding the sheets is located under the path and along the path of transporting the sheets from the upstream portion of the chain conveyor 1 to the suction roller 6 along the width of the sheet. The device for guiding the sheets (FIG 2-4). Consists of rods 7 for guiding the sheets and suction 11 (their boxes 8 with a large area, fortified between the rods for guiding the sheets fixedly on transverse cross-beams 10. Rods 7 For the direction of the sheets, some of which are arranged across the width of the sheets, fastened at both ends on the transverse pipe 13 by means of clamping screws 22 and moved perpendicular to the direction of transport of the sheets. The suction boxes 8 (Fig. 2-) are positioned in In the faceplate mode (Fig. 3), the rods 7 for guiding the sheets and the suction boxes 8 are approximately the same distance from the sheet 9. The device for guiding the sheets is preferably made so that the suction boxes 8 lie slightly above the rods 7 for guiding the sheets. In the face printing mode and printing by turning (Fig. K), the suction boxes 8 are under the rods 7 for guiding the sheets. The rods 7 for guiding the sheets and the suction boxes 8 are connected to an air supplying device. The suction boxes 8 are connected to the suction pipe 23, the suction boxes B located close to each other across the width of the sheet, refer to the suction pipe 23. The suction air supply to the suction boxes 8 and the rods 7 to guide the sheets occurs independently of each other. The intake air duct for the rods 7 for guiding the sheets is not shown, the rods 7 for guiding the sheets and the suction boxes 8 on the surface facing the sheet 9 are equipped with nozzles 18 (FIG. 5). Suction boxes 8, located across the width of the sheet, by means of the first and second arms 13 and 14, hingedly connected to
    transverse traverse 10, connected to the wall of the sheet-cutting device 12. The first and second levers 13 and form with the suction box 8 hinge three-part 13, 8, 14, in which the suction box 8 is made in the form of a rod. Along the transportation route of the sheets several p {zasysschivayushchikov B are sequentially located. The successively connected pick-ups 8c of the two sides are connected to each other by means of a longitudinal rod 11 fixed on the transverse yoke 10.
    A first hinge four-bar 13V 8,1 is connected with a hinge pin 15 and a hand lever 16, made in the form of a crank lever, and a hand lever 16, A hand lever 1b, a hinge pin 15 and the first lever 13 are turn-connected. The hand lever 16 is also located, the first and second levers 13 and 1 on the wall of the sheet device 12. For fixing the end position of the suction boxes 8 in the position of the front seal and the front seal, fixed stops 20,, are provided for turning. A straightener of 21 sheets located with two ctopoHs on the first cross traverse Itl.l is located in front of the device for guiding the sheets.
    The invention is not limited to the present version.
    For example, in the direction of transporting the sheets m (you can place only one suction box 8 in the turning points of the chain conveyor 1 or directly in front of the suction roller 6,
    Suction boxes 8 do not necessarily have to be made in the form of a connecting rod 13, 8, H. The main thing is that when switching from the front print to the print with a turn and the front print and vice versa, it is possible to quickly and cost-effectively switch the suction Ya4iki 8, Instead of Suction pins 8 can also use injection and suction elements with a large area which, according to the aerodynamic paradox, create a vacuum on the sheet 9. The use of the proposed device for guiding the sheets is possible not only in the sheet inlet device, but also along the sheet transport path
    between or under printers.
    The device works as follows.
    After the last ink has been applied, the grippers 3 receive the front edge of the sheet 9, which is continuously transported along the chain conveyor 1 through the leaflet device.
    and stacks on the slipway 5. I
    When the front printing rods 7 for 1
    sheet directions and suction boxes 8 are located approximately in the same plane. The rods 7 for guiding the sheets and / or the suction boxes 8 are loaded with suction air, which through the nozzles 18 acts on the sheet 9 and attracts it to the device for guiding the sheets, so that the sheet 9 is transported through the sheet ejection device
    Spreader 21 sheets .Turned in the direction of transporting sheets. It is loaded with suction air. In a known manner, by stretching the 21 sheets, the sheet bending resulting from the printing process is eliminated.
    When switching to a face seal and a seal with a turn, the control of the hand lever 16 in the direction of the arrow (Fig. 1) rotates the hinge quadruple 13, 8, the end position (Fig. 2, dotted line), which is adjustable and limited by the stop 20 .. 1, the fixation of the final position occurs, as in the position of the front seal, due to the own weight of the hinge four-bar 13 8, 1C. In the same way, the straightener of 21 sheets is taken out of the path of the transgurting.
    The clamping screws 22, the fixing rods 7 for guiding the sheets, are released, the rods 7 for guiding the sheets are adjusted to print-free print spaces and clamped. The connection of the hinge four-bar 13, 8, 14 with the longitudinal rod 11 provides the possibility of simultaneous switching of all the suction boxes 8 in one motion. management
