Definitions

  • the invention relates to a sheet-fed printing machine according to the preamble of patent claim 1.
  • the printing cylinder has printing saddles separated by cylinder pits, the circumferential length of the printing saddles being adapted to the sheet to be printed and the cylinder pits lying in between are required to accommodate the sheet grippers.
  • the present invention has for its object to provide a printing cylinder with a practically closed surface and with adapted transfer devices that allow the transport of sheets in a sheet printing machine and which avoid the disadvantages that occur in printing cylinders with cylinder pits.
  • the printing cylinder with its practically steady, closed surface rolls continuously on the cylinder printing the image, which is in particular a screen printing cylinder in a screen printing machine, a plate cylinder in a intaglio printing machine or a blanket cylinder in an offset printing machine for single-sided offset printing can act.
  • the structure and surface of the printing cylinder are each adapted to the type of printing press.
  • the sheet-fed printing machine has a screen printing cylinder 1, the circumference of which is formed by a cylindrical screen printing stencil 1a and in the interior of which the ink bead 1b accumulated by a doctor blade 1c is indicated, as well as a printing cylinder 2 interacting with this screen printing cylinder 1, both cylinders 1, 2 form the printing gap between them, through which the sheets B are guided by the printing cylinder 2 for printing in the direction of the arrow.
  • the printing cylinder 2 interacts with two transfer cylinders 3 and 4, of which the cylinder 3, as the transfer cylinder, transports the sheets fed from a further transfer cylinder 29 to the printing cylinder 2 and the transfer cylinder 4, as the transfer cylinder, takes over the printed sheets from the printing cylinder 2 and for further transport to one passes further transfer cylinder 30.
  • all cylinders are of the same size and dimensioned so that there is space for two arcs on their circumference.
  • the directions of rotation of all cylinders are indicated by arrows.
  • the area occupied by a sheet on the circumference of a cylinder is referred to as the printing segment of this cylinder; the cylinders therefore have two pressure segments, each of which corresponds to half a cylinder circumference.
  • the pressure cylinder 2 consists essentially of a closed cylindrical surface. At the beginning of each pressure segment, viewed in the direction of cylinder rotation, a suction bar 5 or 6, which is parallel to the cylinder axis, is embedded in the pressure cylinder 2 and has suction openings opening onto the cylinder circumference and is connected to a vacuum source.
  • the two transfer cylinders 3 and 4 interacting with the printing cylinder 2 are specially designed, since in the conventional transfer cylinders equipped with grippers the grippers could not open because of the closed surface of the printing cylinder 2. Therefore, the two transfer cylinders 3 and 4 are each equipped with combinations of suction strips and immersion gripper arrangements.
  • the transfer cylinder 3 has two suction bars 7 and 8 lying opposite one another, of which the suction bar 7 lies in the area of a diving gripper arrangement 9 with the diving grippers 10 and the other suction bar 8 lies in the area of a diving gripper arrangement 11 with the diving grippers 12.
  • the other transfer cylinder 4 has two opposite suction bars 13 and 14, of which the suction bar 13 lies in the area of a plunger gripper arrangement 15 with the plunge gripper 16 and the other suction bar 14 in the area of the plunge gripper arrangement 17 with the plunger grippers 18.
  • the suction strips 7, 8, 13, 14 are in register with the suction strips 5, 6 of the impression cylinder, i.e. each at the beginning of a sheet support surface of the transfer cylinders 3, 4, and are designed to be elastically flexible in the radial direction, so that in each case a rigid suction strip 5 or 6 of the pressure cylinder 2 cooperates with an elastic suction bar 7, 8, 13 or 14 of the transfer cylinders 3 or 4.
  • the immersion grippers are arranged in gaps in the suction strips, as in FIG. 4 for those with suction openings 7a and gaps 7b provided squeegee 7 is illustrated.
  • the gaps 7b are so deep that the immersion grippers 10 can be completely immersed therein.
  • the suction openings 7a branch off from a common suction channel 7c, which can be connected to a vacuum source.
  • the immersion grippers 10 and 12 of the transfer cylinder 3 are controlled for opening and closing by a cam disk 19 arranged stationary on the axis of this cylinder and with regard to their immersion movement by another cam disk 20 arranged stationary on the cylinder axis.
  • the immersion grippers 16 and 18 of the transfer cylinder 4 are controlled by the two cam disks 21 and 22. All immersion gripper arrangements are of identical design and are described in more detail with reference to FIG. 3, which shows an enlarged view of the transfer cylinder 3.
  • a cam roller 25 which rolls on rotation of the cylinder 3 on the cam disc 19, which represents the control curve for opening and closing the immersion grippers 10 and 12 and is shaped accordingly.
  • the cam roller 25 is located on the radially outward area 19a of the still disc 19, the immersion grippers assume their closed position, otherwise their open position. The change between these two gripper positions takes place by a slight pivoting around the gripper shaft, that is to say the gripper shaft 23 in the gripper arrangement 9 with the plunger grippers 10.
  • the angle lever 26 can be pivoted at its other, inner end about an axis 27 which is mounted in a stationary manner in the cylinder 3 and has in its center, that is to say at its angle corner, a rotatably mounted cam roller 28 which rolls on the other cam disk 20 and which provides a guide curve for the diving movement of the diving gripper forms and is shaped accordingly.
  • a rotatably mounted cam roller 28 which rolls on the other cam disk 20 and which provides a guide curve for the diving movement of the diving gripper forms and is shaped accordingly.
  • the change between the two positions takes place by swiveling around the fixed axis at the inner end of the angle lever, in the immersion gripper arrangement 9 thus by swiveling the angle lever 26 around the axis 27, the non-stationary gripper shaft 23 with the immersion grippers 10 being displaced essentially in the radial sense .
  • the gripper 10 assumes its open position and is in the lowered position, while the gripper 12 assumes its closed position and is in the raised position.
  • the transfer cylinder 3 which acts as a transfer cylinder, takes over a sheet coming from the customarily designed transfer cylinder 29 (FIG. 1) by the immersion grippers 12 located in their raised position grasping the front edge of the sheet and being adjusted into its closed position, which they have just assumed in FIG. 1.
  • the transfer cylinder 3 continues to rotate, the elastic suction elements of the suction bar 8 arranged between the immersion grippers are connected to the suction air source via a corresponding suction air control and therefore suck the Bow on.
  • the immersion grippers 12 then open (FIG. 2), so that the sheet is now held only by suction on the suction bar 8. Then the grippers 12 are lowered into their immersion position, in which they are located below the peripheral surface of the transfer cylinder 3, as shown in FIG. 1 for the grippers 10.
  • the sheet still held by the suction bar 7 is transferred to the suction bar 6 of the pressure cylinder 2 by switching off the suction air at the suction bar 7 and switching it on at the suction bar 6. Since the suction strips of the transfer cylinders are elastically flexible in the radial direction, slight fluctuations in the thickness of the paper and differences in the curvature during sheet transfer can be compensated for.
  • the sheet taken over by the suction bar 6 of the printing cylinder 2 is guided through the printing nip, printed there and then transferred to the transfer cylinder 4 functioning as the takeover cylinder (FIG. 1) by applying suction air to the suction bar 14 of the transfer cylinder 4 and the suction air to the suction bar 6 of the printing cylinder 2 is switched off.
  • the immersion grippers 18 are in their lowered and open positions.
  • these immersion grippers 18 are raised (FIG. 2) and moved into their closed position so that they now hold the bow; the suction air is then switched off on the suction bar 14.
  • the sheet is transferred in the usual manner the immersion grippers of the transfer cylinder 4 to the grippers of the transfer cylinder 30.
  • the transfer or transfer of a sheet between the pressure cylinder 2 and the transfer cylinder 3 or 4 takes place in each case by alternately switching the suction air off and on at the relevant suction strips of the cylinders, while the immersion grippers of the transfer cylinders assume their submerged immersion position.
  • the immersion grippers 10 and 12 of the transfer cylinder 3 are adjusted to take over an arc in the raised position before they reach the transfer cylinder 29, while the immersion grippers 16 and 18 of the other transfer cylinder 4 are transferred of a sheet on the transfer cylinder 30 are moved from their raised position to the lowered position before they reach the impression cylinder 2 again.
  • Two sheets are transported on the cylinders at the same time; e.g. a sheet is printed according to FIG. 2 while the following sheet is being transferred to the printing cylinder 2.
  • the screen printing machine in turn has a screen printing cylinder 1, a printing cylinder 2 interacting with it, two transfer cylinders 33 and 34 cooperating with the printing cylinder 2, which act as transfer or transfer cylinders, and another transferring the sheets onto the transfer cylinder 33 Transfer cylinder 39 and a further transfer cylinder 40 taking over the sheets from the transfer cylinder 34.
  • all cylinders are the same size and dimensioned so that there is space for two arcs on their circumference.
  • the impression cylinder 2 is constructed exactly like the impression cylinder 2 in the first embodiment according to FIGS. 1 to 3 and in turn has two diametrically opposed ones Squeegees 5 and 6 made of rigid material.
  • the two transfer cylinders 33 and 34 cooperating with the pressure cylinder 2 are each equipped with two somewhat elastically flexible suction strips 35, 36 and 37, 38, respectively, and therefore have no grippers.
  • the sheet transfer from the transfer cylinder 33 to the printing cylinder 2 and from this to the transfer cylinder 34 takes place, as in the first exemplary embodiment, by alternately switching the suction air off and on at the relevant suction bars when these pass each other, so that the leading edge of the sheet from the suction bar of the receiving cylinder is sucked in and at the same time can detach from the squeegee of the transferring cylinder.
  • the transfer cylinders 39 and 40 are equipped with conventional sheet grippers which, when interacting with the transfer cylinders 33 and 34, take over the front edge of the sheet in question by closing, while at the same time the suction air of the relevant suction bar of the transfer cylinders 33 and 34 is switched off.
  • the transfer cylinder 39 is provided with cylinder pits 43 and 44 to accommodate its sheet grippers 41 and 42.
  • the grippers 41 and 42 are seated at the end of an angle lever 47 and 48, which can be pivoted about an axis 45 and 46 mounted in the cylinder pit 43 and 44, respectively.
  • a cam roller 49 or 50 is mounted, which rolls on a cam disc 53 which is fixedly mounted on the cylinder axis and forms a guide curve.
  • the other transfer cylinder 40 with its grippers 54, 55 is constructed in exactly the same way as the transfer cylinder 39 described above.
  • the suction strips 35 and 36 of the transfer cylinder 33 are provided with corresponding gaps, as in FIG 6 for the suction bar 35 with its gaps 35b, which enable the open grippers of the transfer cylinder 39 to be immersed.
  • the suction openings 35a are in turn connected to a common suction channel 35c.
  • suction strips 37 and 38 of the transfer cylinder 34 are designed so that the opened grippers 54, 55 of the transfer cylinder 40 can pass through the transfer cylinder 34 unhindered.
  • a sheet which is held on the transfer cylinder 39 by the closed grippers is thus transferred to the transfer cylinder 33 by connecting the relevant suction bar of this transfer cylinder to the compressed air source and at the same time opening the relevant sheet grippers of the transfer cylinder 39 .
  • the sheet is transported on the transfer cylinder 33 to the impression cylinder 2 and transferred to it by the relevant squeegee of the Printing cylinder 2 connected to the vacuum source and at the same time the suction strip in question of the transfer cylinder 33 is switched off by the suction air.
  • the sheet is passed on the printing cylinder 2 past the screen printing cylinder 1 and then transferred to the other transfer cylinder 34 by switching off and on the suction air accordingly; from there the sheet reaches the transfer cylinder 40, the grippers of which are closed for this purpose when passing through the transfer cylinder 34.
  • FIG. 7 shows another preferred embodiment of the suction bars of the pressure cylinder 2 and the transfer cylinders 33 and 34, specifically in the case of the gapless suction bar 6 of the pressure cylinder 2 interacting with the sheet transfer with the suction bar 38 of the transfer cylinder 34.
  • the two bars are in section , parallel to the cylinder axes, and for the sake of clarity shown at a small distance from each other.
  • the suction bar 6 is provided with an arrangement of material sections, each of which includes a number of suction openings 6a and consists of adjacent areas made of elastic material 6e and rigid material 6s.
  • material sections are provided in the suction bar 38 of the transfer cylinder having gaps 38b, which also each include a plurality of suction openings 38a and consist of adjacent areas made of elastic material 38e and rigid material 38s.
  • the arrangement is such that an area of elastic material of one suction bar always interacts with a area of rigid material of the other suction bar during sheet transfer. In this way a register-based sheet transfer is guaranteed and at the same time it is ensured that slight variations in the thickness of the paper can be compensated.
  • FIG. 8 schematically shows an offset printing machine according to the invention, which has a plate cylinder 62, a rubber cylinder 61 of the same size colored by this plate cylinder, a printing cylinder 2, two transfer cylinders 3 and 4 and two further transfer cylinders 29 and 30.
  • the structure and arrangement of the printing cylinder 2 and the transfer cylinders 3, 4, 29 and 30 are the same as described in the exemplary embodiment according to FIGS. 1 to 3.
  • the plate cylinder 62 carries a seamless plate sleeve with two offset printing patterns
  • the blanket cylinder 61 is provided with a seamless blanket sleeve.
  • the printing cylinder 2 with a closed peripheral surface is particularly advantageous, since a change in the printing tension between the blanket cylinder 61 and the printing cylinder 2 is prevented.
  • the cylinder printing the image is therefore the rubber cylinder 61, by means of which a sheet is printed on one side on the printing cylinder 2.
  • Figure 9 shows a simplified embodiment of a screen printing machine according to the invention with a screen printing cylinder 1 and a printing cylinder 2, the suction strips 5 and 6, as described earlier, and, without dispensing transfer cylinders, directly with gripperless devices for transferring an incoming, unprinted sheet and cooperates to take over and forward a printed sheet.
  • the unprinted sheets are fed individually from a known sheet feeder 65 via a suction belt table 66 to a known front mark device 67, at the front mark of which the sheet is in the known state in the idle state in longitudinal and Side direction is aligned.
  • the actual sheet transfer device consists of a sheet vibrating device with suction cups, namely a rocking gripper 68, which has a suction bar 69 at its end and swings back and forth in the direction of the double arrow.

  • the vibrating gripper 68 is accelerated to machine speed, and the sheet is transferred in phase to the suction bar 5 of the pressure cylinder 2 then passing the transfer point, by switching off the suction air on the suction bar 69 of the rocking gripper 68 and switching it on on the suction bar 5 of the pressure cylinder 2.
  • the suction bar 69 of the oscillating gripper 68 is preferably constructed in the same way as the suction bar 38 shown in FIG. 7, but without gaps, and the suction bars 5 and 6 of the pressure cylinder 2 are designed like the suction bar 6 shown in FIG. 7, in a mirror-image arrangement of the material areas .
  • the suction bar 69 of the rocking gripper 68 interacts with a suction bar 5 or 6 of the pressure cylinder 2, a rigid material section of the one suction bar interacts with an elastic material section of the other suction bar, as described with reference to FIG. 7.
  • a suction belt table 66 with a suction belt instead of a suction belt table 66 with a suction belt, another known conveyor belt or another known sheet conveying device can also be provided for transporting the sheets from the sheet feeder 65 to the front mark device 67.
  • the sheet transfer device consists of a suction belt device 70, which works, for example, with two parallel suction belts, each of which is one third of the sheet width.
  • a suction belt device 70 which works, for example, with two parallel suction belts, each of which is one third of the sheet width.
  • the suction air of the suction belt device 70 is controlled in such a way that the sheet is stretched and transported on the underside of the suction belts over a delivery stack 71 and is then dropped onto the stack by switching off the suction air, where it is aligned with known straight pushers.
  • the suction belt device 70 is located on the same side of the pressure cylinder 2 as the oscillating gripper 68, so that the sheets which are removed from the pressure cylinder 2 advantageously reach the top of the suction belts.
  • the suction belt device 70 in the example according to FIG. 9 can also be mounted on the left side of the printing cylinder 2, the peripheral speed of which is directed downwards there, so that the sheets removed from the printing cylinder 2 reach the underside of the suction belts directly and are sucked in there will.
  • FIG. 10 shows a further simplified exemplary embodiment of a screen printing machine with a screen printing cylinder 1 and a printing cylinder 2, which in turn has two suction strips 5 and 6, as described above.
