Definitions

  • a machine with reciprocating motion for multisystem printing machines of the type that comprises a frame with an entry and exit, through which a mean respectively enters and exits, on which is going to be printed or has been printed a motif, fixed rotating cylinders over which the cited mean circulates, characterised in that it comprises a linear motor that controls the reciprocating motion, at least one rotating cylinder joint to the mentioned linear motor, at least one support cylinder joint to the frame over which the cited mean circulates, being the next cylinder after the rotating cylinder and in a different plane to it and at least one guide cylinder that controls the movement of the mean inside the machine, the support cylinder is away from the rotating cylinder when the movement of the mean is away from the multisystem printing machine and approaching to the rotating cylinder when the movement of the mean is approaching to the multisystem printing machine.
  • NILPETER A/S refers to a method and a cylinder arrangement for a printing apparatus in which printing plates of punching of different lengths may selectively be mounted on the same plate cylinder, and wherein the web to be printed or punched may be moved past the cylinder at a substantially constant speed.
  • the cylinder pairs are physically independent such that the path of travel of the material as it moves from one nip to the other is not constrained by the size of the cylinders and may follow a substantially straight path as it moves from one nip to the other.
  • Each of the cylinders in each pair is rotatable such that each pair periodically performs an operation along a substantial length of the material during respective operative intervals.
  • Means in the form of a looper roll are provided for varying the velocity of the sheet material as it passes the first nip.
  • the looper roll has a cyclical operation during one portion of which the material is caused to move at a constant velocity and during another portion of which the material is caused to move at a non constant velocity.
  • the constant velocity portion of the looper roll cycle causes the velocity of the material to match the circumferential speed of the cylinders. This occurs during the operative interval of the first cylinder pair. As a result, the operation performed by the first cylinder pair may take place over a substantial length of the material.
  • European Patent 1026111 "INJECTOR FOR ROTARY WEB PROCESSING DEVICE WITH FIXED DIAMETER BASE”, in the name of Mr. Allan R. PRITTIE, of 2000, which refers to a unique rotary die cutting system including an injector mechanism that accurately positions a moving continuous web in such manner as to permit the implementation of a set of constant diameter cylindrical bases onto which are mounted by various means a pair of removable complementary steel sheet dies.
  • the integrated action of the novel sub-sections of the invention permits significant improvements in economies of operation relative to exiting rotary converting technologies.
  • the "infeed” - “outfeed” movement is horizontal and driven by a mechanical transmission.
  • the first are vibrations that are produced, and which involves movements in the pieces leading to a certain clearance in them, so that the machine needs constant maintenance.
  • the second is due to material wear in consequence of the own transmissions.
  • This invention is intended to eliminate such vibration and thus, significantly reduce material wear.
  • a machine has therefore been configured in which a support cylinder is solidly mated with a linear motor so that, when the latter is moved in one direction or the other, the cylinder increases or reduces the paper distance to the preceding or succeeding multisystem unit allowing the infeed - outfeed operations, as applicable.
  • An object of this invention is a machine with reciprocating motion for multisystem printing machines of the type that comprises a frame with an entry and exit, through which the mean to be printed or has been printed with a design, respectively enters and exits, fixed rotating cylinders over which the cited mean circulates, characterised in that it comprises a linear motor that controls the reciprocating motion, at least one rotating cylinder joint to the mentioned linear motor, at least one support cylinder joint to the frame over which the cited mean circulates, being the following cylinder after the rotating cylinder and in a different plane to it and at least one guide cylinder that controls the movement of the mean inside the machine, the support cylinder is away from the rotating cylinder when the movement of the mean is away from the multisystem printing machine and approaching to the rotating cylinder when the movement of the mean is approaching to the multisystem printing machine.
  • Figure 1 illustrates a frame 1, with fixed cylinders 2, means 3 that define an entry 4 and exit 5, a moving plate 6 with its rotating cylinder 10, guides 7, magnet 8, guide cylinder 15, support cylinder 14 and fixed winding 9.
  • Figure 2 shows the frame 1, mean 3, moving plate 6, guides 7, magnet 8, fixed winding 9, rotating cylinder 10 and upper plate 12.
  • Figure 3 contains the frame 1, mean 3, moving plate 6, guides 7, magnet 8, fixed winding 9, upper plate 12, fans 11 and power supply means 13 for the fixed winding.
  • this machine can be placed before or after one of those that forms part of the multisystem printing (offset, wet printing, dry printing, stamping, silk screening, die stamping and hot stamping etc). In fact, it is recommended that one be positioned before and another behind in order to a better manage of mean (this is label paper in this embodiment).
  • a linear motor has also been chosen for this embodiment in which winding 9 is fixed because this avoids cable fatigue, however, magnet 8 could be fixed and winding 9 be the moving element (then fixed to him, the rotating cylinder 10), although it would be necessary to employ a cable that is highly resistant to fatigue, which would increase costs.
  • the machine from the multi-system group will be flexographic.
  • the flexographic machine cylinder plate (not shown) has printed in the mean 3, the latter continues moving forward, but the cylinder plate has to stop because part of it does not have a blanket so that if it does not move backwards after the paper passes, a large amount of unprinted paper material would be lost.
  • the machine of this invention is of the type described in the previous paragraph.
  • This exemplary embodiment shows the machine installed after the flexographic machine, being the explanation of the one that is placed before the same in inverse mode.
  • the controlling cylinder 15 will allow the mean to move in this direction.
  • the fixed winding 9, which is installed on an upper plate 12 fixed to the frame 1 repels the magnet 8 (which is separated by a predetermined distance from fixed winding 9), which, because said magnet 8 is fixed to the moving plate 6, it will drag the latter and, in turn, rotating cylinder 10, approaching said cylinder 10 to the flexographic machine.
  • support cylinder 14 is moved away from rotating cylinder 10 when the forward movement direction of mean 3 is away from the flexographic machine and moved closer to rotating cylinder 10 when the forward movement direction of mean 3 is towards the multisystem printing machine.
  • mean 3 advances due to drive cylinder 15 and the processor sends a signal to the fixed winding 9 so that it attracts magnet 8, and with this then the moving plate 6 and rotating cylinder 10.
  • winding 9 is fixed and the moving part is plate 6 is that in this way, the power supply means 13, because of the high rate and high accelerations, avoids cable fatigue.
  • Said fixed winding 9 is mounted on an upper plate 12 on which fans 11 are also mounted.
  • Moving plate 6 is rigid. In fact, in one exemplary embodiment, one that it follows a deformation proportion of 0.01 mm for a force of 11,000 N was found to be valid, (although this could vary in function of materials and other variables).
  • magnet 8 can be fixed and the winding 9 moved without changing the basic idea of the invention and, in this way, winding 9 moves over guides 7 joint to frame 1, at least one magnet 8, fixed underneath the referred winding 9 and separated from said winding (9), and power supply means for said fixed winding 9.
