Definitions

  • the invention relates to a printing press with a pair of input rollers for conveying a piece of printing material to be printed piece by piece, a printing device and a cutting device for the printed piece of web.
  • the object is achieved to provide a printing machine of this type, with which it is possible to print on a selectable one of a plurality of printing material webs, which webs can be provided, for example, of different widths, different colors or with different forms.
  • Advantageous embodiments of this machine are the subject of claims 2 and 3.
  • the development of the invention according to claim 5 makes it possible to arrange the guide channels for a relatively large number of printing material webs relatively close to each other by using little space-consuming grippers as conveying devices, their gripping and releasing movement controlled by means that occupy practically no space are.
  • Claims 6-9 give advantageous embodiments of these grippers and claims 10 and 11 indicate further developments of the conveyor device.
  • Fig. 1 denotes the input roller pair, 2 the needle head and 3 the pressure bar of the printing device. 4 the knife blade which, together with a counter knife formed on the pressure bar, forms the cutting device of the printing machine designed as a dot matrix printer.
  • the needle head 2 is displaceable and driven transversely to the plane of the drawing, such as in the europi described patent application No. 80101133.9.
  • the knife blade 4 can be driven as described in the European patent application No. 80101205.5 and the ribbon transport, not shown, can be carried out as described in the European patent application No. 80101248.5.
  • the known dot matrix printers of this type work for printing on pieces of one and the same paper web so that the input rollers 1 move the paper web to be printed into its printing position, optionally for line-by-line printing in several printing positions one after the other, after the printing pushes it into the cutting position and after the cutting of the printed piece of paper in the printing position, possibly in the first printing position.
  • the dot matrix printer 1-4 works essentially the same, but with the difference that the pair of rollers 1 does not push the paper web back into the printing position after cutting, but, as explained further below, pushes it further, namely until it leaves the nip 5 Rollers 1, and that the paper web is inserted between the rollers 1 before each printing operation and is advanced by them into the printing position, possibly the first printing position.
  • each flat guide channel For seven paper webs that can be optionally printed in any order, there are seven flat guide channels, each formed between two parallel channel walls. Two of which are designated 6 and 7, arranged in a fan shape and directed toward the side of the clamping gap 5 facing away from the printing device 2, 3.
  • two guides are provided between the channel walls of each guide channel arranges, which are held by lugs reaching into holes in the channel walls.
  • Several rows of holes are provided to adapt to different paper tape widths, see the channel wall 61 of the channel 6, the guides 62 with the lugs 63 and the rows of holes 64 in FIG. 2.
  • the guide channel 6 is a gripper 8
  • the guide channel 7 is the same gripper 9 and the other guide channels each have the same gripper for advancing and pushing back the paper web guided in the relevant channel.
  • These paper webs are not shown in Fig. 1. 4 and 5, the paper web in the guide channel 6 with 11, in the guide channel 7 with 12.
  • each gripper is designed and can be displaced by means of a drive device along a feed and return path which extends over a part of the associated channel facing the clamping gap 5 all channels are the same, and approximately corresponds to the distance that the fan-shaped arrangement of the channels from the clamping gap 5.
  • the gripper 8 is at the end of the feed path (ie the start of the feed path), and the gripper 9 is at the start of the feed path (ie the end of the feed path).
  • the grippers are, as will be explained in connection with FIGS. 4 and 5, controlled in such a way that an end part of the feed path, the release movement of the gripper, the coinciding initial part of the retraction path, accordingly the gripping movement of the gripper and the remaining part of the feed and return path Gripping position of the gripper is assigned.
  • each gripper is adapted to the circumferential speed and direction of rotation of the pair of rollers 1 along the entire feed and return path. Basically, it is sufficient if the speed of the gripper is the same or slightly higher immediately before and during the release of the gripper and the speed of the gripper is equal to or slightly less than that of the pair of rollers during and immediately after the gripping movement all the same distance from the clamping gap 5. This distance is somewhat smaller than the feed and return path of the grippers, and each gripper is in the rest position shown in FIG. 1 for the gripper 9, in which it is in the gripping position, that is, it grips the Paper web and holds it.
  • the gripper which is assigned to this paper web or its guide channel, is advanced, whereby it grips the paper web takes along.
  • the gripper approaches the end of its feed path, the paper web gets into the nip 5 of the pair of rollers 1, shortly thereafter the gripper carries out its release movement, it remains in this position, and the pair of rollers 1 pushes the paper tape forward into the printing position in which it is printed, and further to the cut-off position in which it is cut, and then backwards.
  • the gripper Shortly before the paper web pushed backwards leaves the nip 5 of the pair of rollers 1, the gripper begins its push-back movement, first carrying out its gripping movement and then taking along the paper web which leaves the nip 5 of the pair of rollers 1. At the end of the return path, the gripper is again in its rest position and the free end of the paper web formed by cutting off the printed piece of the paper web is in a position which the end that was present before the cutting had before the whole process. This is due to the fact that the gripper feed ended shortly after the original paper web end had entered the nip 5, the feed path began shortly before the new paper web end came out of the nip, and the feed path is equal to the feed path.
  • the gripper and rollers are driven by stepper motors, as these can be precisely controlled for certain rotations.
  • the required rotations of the rollers result from the distances of the gap between the pressure point and the cutting point.
  • the specified dimensioning of the feed and return feed speeds of the gripper ensures that the paper web is neither compressed nor pulled when it is temporarily conveyed by both the gripper and the pair of rollers.
  • Each gripper has as F ig. 2 - 5 show the example of the gripper 8 and partly also for the gripper 9, two spring sheet metal strips 81 and 91, which are held at a distance from one another at their ends by spacers, are then cranked towards one another and diverge towards the center.
  • the spring metal strips 81 of the gripper 8 are arranged on the outside of the channel walls 61 of the associated guide channel 6, and their cranks are guided thereon.
  • a gripping jaw 82 or 92 of two pairs of gripping jaws and a cam 83 or 93 of a pair of cams arranged between the gripping jaw pairs 82 or 92 are fastened to the inside of the spring metal strips 8L or 91.
  • the gripping jaws 82 and 92 each grip through an opening 65 and 75 in the channel walls 61 and 71, and the cams 83 and 93 each grip through an opening 66 and 76 of the channel walls El and 71, respectively. These openings are designed as elongated holes to enable the gripper 8 or 9 to move forwards and backwards.
  • the spring sheet strips 81 'k.-zw. 91 are pretensioned such that the gripping jaws 82 and 92 are pressed together when the gripper 8 and 9 are at rest, and the cams 83 and 93 do not touch one another (and also the paper web), so that the spring force of the spring-metal strips 81 and 91 acts completely on the gripping jaws.
  • the pairs of gripping jaws 82 and 92 reliably grip the paper web 11 and 12 in channels 6 and 7, they consist of a material (plastic) with a high coefficient of friction.
  • the cams 83 and 93 are made of a material (another plastic) with high sliding properties. so that they slide easily on their assigned control surfaces, as described below.
  • the ceilings 83 and 93 of the grippers 8 and 9 run on their control and gripping movement on control surfaces 67 and 77, which are formed on wedge-shaped bulges 68 and 78 of the channel walls 61 and 71. Otherwise, the cams 83 and 93 protrude through the elongated holes 66 and 76 in the channel walls 61 and 71, respectively. However, these elongated holes 66 and 76 are shorter than the elongated holes 65 and 75 into which the gripping jaws 82 and 92 protrude, because the cam 83 and 93 slide on the control surfaces 67 and 77 at the end of the feed and start of the push-back path.
  • the gripper 8 is at the end of the feed path and its cams 83 have run onto the control surfaces 6 ", so that its gripping jaws 82 are lifted off the paper web 11.
  • This (11) - as above described - further advanced by the pair of rollers 1 and pushed back again after the printing and cutting process, when the gripper 8 then executes its push-back movement, the cams 83 run off the control surfaces 67, which causes the gripping movement and the paper web 11 from the gripping jaws 82 is gripped and pushed back on the return path of the gripper 8 until the gripper 8 has the position in which the gripper 9 is shown, the paper web 11 thereby being held in place.
  • each gripper is connected both to a pair of tension springs, which act in the return direction, and to a cable winch, which acts against the tension springs, as in FIGS. 1 and 6 and using the example of the gripper 8 and partly for the gripper 9 is also shown in Fig. 2.
  • the gripper 8 is connected to a pair of tension springs 84, which is supported in a stationary manner, and to a pair of elongation-resistant cables 85.
  • the corresponding ropes of the gripper 9 are designated by 95 in FIGS. 1 and 2. In Fig. 1 the rope of the pair 85 visible there is only partially shown.
  • Each rope 85 or 95 runs via a freely rotatable deflection roller 86 or 96 to a rope sheave 87 or 97 to which the rope end is attached.
  • the pulleys of each pair 87 and 97 are fixed on a shaft 88 and 98, the rotation of which by stops, not shown, in the direction of pull of the springs. 84, corresponding direction is limited, whereby the rest position of the grippers 8 and 9 is defined.
  • the coupling members 89b and 99b have a symbolically illustrated external toothing, which meshes with a gear 13 or 14 of a symbolically illustrated gear train 15, which is driven by a stepper motor 16, and the coupling elements 89b and 99b and the corresponding ones, even when the coupling member is axially displaced drives further coupling members together, but this only drives the shaft whose clutch is engaged.
  • the stepper motor 16 is controlled so that the rotation of the Gripper advance or ruck feed path corresponds.
  • their electrical connection cable, e.g. 89c, 99c is wound with so much play around the shaft in question, for example 88, 98, that it unhindered can rotate according to the forward and backward movement of the gripper.
  • the entire machine is controlled by an electronic program control device (not shown), which in each case triggers the engagement of the clutch (for example 89a / 89b) which is assigned to the gripper (for example 8) of the guide channel (for example 6) for the selected paper web (for example 11), controls the drive of the stepper motor 16 and the pair of rollers 1 and the printing and cutting process.
  • Cboth the stepper motor (not shown) driving the pair of rollers 1 can be controlled exactly according to the feed and return paths to be carried out by the pair of rollers.
  • the feed through which the paper web comes into the printing position, possibly into the first of several printing positions, is not measured by a correspondingly dimensioned rotation of the rollers 1, but is ended when a light barrier 17 (FIG.
  • Photoelectric barrier is before rolling few arranged to operate with the Steueiein 'direction together to trigger a signal when a paper web is used up.
