Definitions

  • the invention relates to a device for the indirect printing of cylindrical parts, with an intermediate printing carrier, and with a device for transmitting a printed image on the intermediate printing carrier or for generating a printed image on the intermediate printing carrier.
  • the printing of cylindrical parts has been carried out for decades in screen printing, in offset printing and in flexographic printing and, for some time, also in the inkjet process (inkjet).
  • the printed image is printed on the cylindrical part to be printed by means of a cylindrical roller.
  • the parts to be printed on the one hand must be fed to the printing unit and then held in a complex manner rotatable against the outer peripheral surface of the printing cylinder, so that the printed image can be transferred to the parts to be printed. Then the parts have to be removed again. This is associated with control movements with accelerations and delays, which are complex at high process speeds and in any case limit the number of executable printing processes per time.
  • the intermediate pressure carrier is formed by an endless belt which is endlessly guided as a closed belt loop over at least two rollers and receives on its side facing away from the rollers outer side of the printed image, so US 4,116,126 . DE 2435251 A1 . DE 199 38 447 A1 ; However, these are not used for printing cylindrical parts.
  • An apparatus with the features of the preamble of claim 1 is known from GB 2512678 A , wherein it is not explicitly stated whether the transfer section of the endless belt runs in one plane and whether the translational delivery of the parts to be printed takes place in the region of the endless belt in one direction and in one plane.
  • the present invention is based on the object, a device of the type mentioned for the indirect printing of cylindrical parts specify which with respect to the supply, support and discharge of the parts to be printed with less and less complex design effort is operable.
  • the endless belt comprises a first supporting flat material and that on its outer side a circumferentially continuous or discontinuous elastically yielding coating of the supporting sheet material is formed for receiving the printed image.
  • the parts to be printed need not be stopped in a printing station, pressed against a platen and accelerated again after printing and removed translationally, but this can be done virtually in a single continuous process. Since the parts to be printed are printed by rolling relative to the transfer section extending in a plane, this can also be done during a continuous translational movement of the parts to be printed, as long as they are rotatably mounted in the region of the flat transfer section, so they can roll against the transfer section. In this way, the design of the feeder structurally simple, since no clocked translational accelerations and delays of the parts to be printed and their tool holder must be performed.
  • a further advantage of the device according to the invention and of the method according to the invention is the fact that the transfer of a print image onto the intermediate print carrier or the production of a print image on the intermediate print carrier can be made simpler, since the possibility exists of transferring or producing the print image again in one level section of the endless belt.
  • a support device be provided within the endless belt, by means of which the endless belt in the transfer section orthogonal to its belt level is sustainable. In this way it can be achieved that the endless belt is not pressed inward by the rolling of the cylindrical parts to be printed, thus maintaining its planar extension in a plane. The print image is thus not distorted.
  • This support means could be realized in the simplest case by a sliding from the inside against the endless belt sliding or support shoe.
  • an adjusting device be provided within the endless belt, by means of which the endless belt in the transfer section orthogonal to its belt plane in the transfer section to the outside so in the direction of the parts to be printed deflected.
  • This further measure makes it possible to shift the transfer section somewhat in the direction of a feed plane of the parts to be printed.
  • This displacement, deflection or infeed of the transfer section can be, for example, in the range of a few millimeters, in particular between 1 and 20 mm with respect to the undeflected course of the endless belt between the two rollers.
  • the parts are rotatably mounted in the feeder. During this time, they are preferably transported translatorily at a constant speed.
  • the support means or the adjusting device is designed such that the length of the outwardly deflectable portion of the endless belt in the drive direction of the endless belt is variable.
  • the support device or the adjusting device advantageously has a plurality of optionally usable support or sliding shoes which have a different length in the drive direction of the endless belt.
  • mutually adjustable rollers or rollers or length-adjustable support elements for the endless belt are provided inside the closed belt loop of the endless belt.
  • the generation of a continuous in the drive direction of the endless belt, so shock or joint-free support surface in the support device or adjusting device is given preference.
  • the adjusting device is designed for a timed operation.
  • This opens up the possibility of printing on parts to be printed with a relatively large diameter, which therefore have a relatively large circumferential length when unrolling, but only with a relatively short in the unwinding print image, the useful capacity, ie the number of parts to be printed per time increase.
  • the adjusting device is moved back from a printing position of the part to be printed and then back in Direction is brought to the next following to be printed part in the printing position.
  • the parts to be printed can be supplied more closely in succession, that is to say with greater useful capacity, and the printed images can be provided in relatively narrow succession on the endless belt as intermediate printing carrier.
  • the support device or the adjusting device comprises a sliding shoe, against which the endless belt slides.
  • This shoe is then applied from the inside, ie against the inwardly facing surface of the closed belt loop. It preferably comprises a support surface lying exactly in one plane.
  • the sliding shoe has a plurality of support webs extending in the transport direction of the endless belt, the web surface of which runs exactly in a support plane. This proves to be advantageous because between the webs positive coupling elements can be passed, which act between the endless belt and the at least two rollers. Irrespective of this, however, the sliding behavior is also more advantageous in the case of strip-shaped support surfaces of the sliding shoe which are delimited by gaps.
  • the feeding device comprises, in addition to a translatory feed, an overriding feed and return movement in the direction of the endless belt or away from the endless belt, where this appears expedient for process engineering reasons.
  • the feed device for the cylindrical parts to be printed is designed such that it supplies these parts against the drive direction of the endless belt in the transfer section. This way, a larger one Relative speed between the endless belt and the parts to be printed at the lowest possible speed of the endless belt and the parts to be printed can be achieved.
  • a positively controlled rotary drive device for the rotatably mounted parts is provided in the feed device such that an outer peripheral speed of the parts corresponds to a relative speed between the endless belt and the translational feed of the parts, when these are in the transfer section reach.
  • This proves to be particularly advantageous because so the desired outer peripheral speed of the rotating parts can be specified exactly, so it is not dependent on a slip between the rotating part and the endless belt during the acceleration phase. In this way, a higher accuracy can be achieved.
  • This proves to be particularly advantageous if not only a single print subcarrier for the transmission of a printed image, but a plurality of successively arranged print subcarriers for the transmission and application of several, especially multi-colored print images are provided.
  • the positively controlled rotational drive device comprises a rack and pinion mechanism.
  • a rack and pinion mechanism may comprise a stationary rack which is rotatably drive-connected via respective gears to a respective bearing means on the workpiece carriers for the respective parts when or before the parts enter the transfer section.
  • the printing device is characterized by a plurality of successively arranged print subcarriers and in that the positively controlled rotary drive means along the plurality of print subcarriers, so that the parts from the first transfer section of the first print subcarrier to the last transfer section of the last Intermediate print carrier without interruption and synchronized with the translatory feed of the feeder are driven in rotation.
  • the device comprises a gravure applicator, so that the printed image by means of gravure, i. from a gravure engraving, is transferred to the endless belt. Furthermore, it can prove to be advantageous if the device comprises a high-pressure applicator, so that the printed image is transferred by means of high pressure to the endless belt. Furthermore, it may prove advantageous if the device comprises an inkjet applicator (inkjet), so that the printed image is produced by means of inkjet application on the endless belt. All of the aforementioned printing techniques and corresponding commissioned works can be used advantageously to form a printed image in the intermediate printing carrier, so the endless belt. When using an inkjet applicator, it proves to be advantageous if it is arranged so that the printed image is formed in a flat portion of the endless belt.
  • the endless belt can be realized in various ways. It typically comprises a first supporting sheet. If, in the course of a printing process, only a single printed image is produced, for example in the case of single-color printing, it may prove sufficient that the endless belt is clamped, ie driven by friction drive, with respect to the rollers and driven.
  • the endless belt may prove advantageous for the endless belt to be a first load-bearing Includes flat material and that the endless belt, in particular the first supporting sheet of the endless belt, in the direction of the rollers projecting protrusions, which engage positively in complementary thereto executed depressions in the rollers.
  • the elastically yielding coating is formed by a second flat material, which is designed as a preferably endless and closed belt loop and is releasably connectable to the first supporting flat material by being on the outer side of the first supporting Flat material is mounted and placed in a slip and play-free driving connection with the first supporting sheet.
  • the second flat material is brought into the slip-free entrainment connection with the first supporting flat material via a form-fitting acting means between the second flat material and the first supporting flat material.
  • the positively acting means form a rear grip both in the drive direction of the endless belt and transversely thereto.
