Definitions

  • the present invention describes an arrangement for the transmission of data in the UHF range between a transmitter / receiver and an RFID transponder, which is arranged in the pressure roller. moreover, the use of this arrangement for locating printing rolls and a method of data transmission using the arrangement are disclosed.
  • RFID transponders has also prevailed in the printing sector, especially in the handling of printing rollers.
  • the RFID transponders are used here for various purposes.
  • the RFID chip is arranged in the peripheral surface (lateral surface) of the pressure roller and read or described regularly during operation.
  • the read head for controlling the RFID transponder is arranged so that the RFID transponder is regularly passed by rotating printing roller at a small distance to this. Since it is provided that the RFID transponder in preferred embodiments also performs the tasks of a positioning mark, the read head is closely spaced from the roll surface and positioned in the vertical direction above the continuous RFID transponder. A data transmission from or to the RFID transponder from a greater distance is not provided according to the purpose.
  • the EP 1 559 572 A1 describes the arrangement of an RFID chip in a printing cylinder, which is designed without its own shaft or journal and is mounted by mounting on a shaft.
  • the RFID chip is positioned either with the material surface finally at the end faces or below the surface when mounted in the lateral surface.
  • Another embodiment shows a method for producing a sleeve, in particular a multilayer sleeve.
  • a very thin planar RFID transponder is inserted during the winding of the layers between them.
  • the RFID transponder stores a wide variety of data, both for identification and for the previous use of the printing roller or sleeve and logistical information.
  • the RFID chip preferably operates in the UHF range.
  • a movable bearing element of a printing machine in which a sensor head is arranged.
  • the bearing element serves to receive the shaft of printing cylinders, but does not have to carry the printing cylinder whose RFID transponder is to be read out.
  • the RFID transponder of the printing cylinder can be RFID chip, a position transmitter or the like. It is shown that the RFID chip is arranged in a collar of the printing cylinder.
  • the reader is located in a portion of the bearing that is shaped so that the reader is directly opposite the RFID chip.
  • the EP 2 090 944 A1 discloses the use of RFID transponders in components of printing machines.
  • the publication teaches to transmit various types, operating and position data via RFID.
  • a concrete teaching for advantageous arrangement of the RFID transponder on certain machine parts of the printing presses is not apparent from the application.
  • the RFID chip is accommodated in the pressure roller or the sleeve. He is doing in the lateral surface or the end faces of the pressure roller or the sleeve.
  • the communication devices that are used for reading or writing the RFID transponder are arranged so that they have the smallest possible distance to the RFID transponder and thus achieve the highest possible signal strength. These designs are very well suited for recording current operating values, topology information and the like, and making them available on demand. Less suitable are these arrangements when it comes to query for logistic processes data of the printing rollers. Such data relate, for example, serial numbers, type designations, previous storage and installation locations and suitability specifications. Such information is usually needed before it comes to mounting the pressure roller in the printing press. Even if the pressure roller is mounted, the corresponding data should be able to be read out or programmed, especially in older machines which do not have permanently installed and adjusted RFID transponder reader / writer devices.
  • the object thus arises of creating an arrangement which makes it possible to program logistic data from RFID transponders on pressure rollers or sleeves or this should be possible in the built-in and uninstalled state of the printing rollers or sleeves and both stationary and portable readers.
  • the object is thus achieved with an arrangement for data transmission in the UHF range between a transmitter / receiver and an RFID transponder.
  • the RFID transponder is arranged in a pressure roller, wherein the pressure roller has a pressure cylinder or sleeve and a shaft or at least axle journals which carry the pressure cylinder or sleeve.
  • the RFID transponder is disposed below the surface of the shaft or a journal or with the surface final, between the end face of the printing cylinder or sleeve and the end face of the shaft or a journal. It is essential that the transmitter / receiver is spaced from the end face of the shaft or journal.
  • the transmitter / receiver has a distance to the end face of the shaft or journal, which is preferably between 1 mm, more preferably 10 mm and most preferably 100 mm and more preferably 1000 mm and the maximum range of the signal.
  • the transmitter / receiver is thus arranged at a distance from the RFID transponder, which is greater than the distance to the nearest outer end face of the shaft or the journal and smaller than the maximum range of the transmitter / receiver.
  • the outer end face of the shaft or axle journal lies on one of the outer ends of the pressure roller. It is thus not meant the end of a journal, which is anchored in the wall of the printing cylinder.
  • transponder axis The parallel to the geometric center axis of the shaft or the journal and the axis passing through the transponder is referred to below transponder axis.
  • the transmitter / receiver is preferably arranged in alignment with this axis.
  • the deviation of the transmitter / receiver from the transponder axis is preferably less than 20 °, more preferably less than 15 °, most preferably less than 10 ° and more preferably less than 5 °. It has proven to be particularly advantageous to position the transmitter / receiver directly in the transponder axis with a deviation of less than 3 ° from this.
  • the angle is measured with the RFID transponder (in particular the geometric center of gravity of the antenna of the RFID transponder) as a vertex.
  • the total distance of the transmitter / receiver to the RFID transponder does not exceed the range of the signal transmission, d. H.
  • the transmitter / receiver is arranged in a geometric straight circular truncated cone, the base of which is determined by the maximum range of the signal (ignoring a curvature due to lobes of the signal) and whose top surface is assumed to be parallel to the base and spaced from the end of the shaft / journal ,
  • the lateral surface is defined by the maximum permissible deviation of the transmitter / receiver from the transponder axis. This maximum permissible deviation extends as described around the transponder axis.
  • the RFID transponder is a commercially available RFID transponder that transmits in the UHF range.
  • the RFID transponder is preferably not equipped with its own energy source, such as a battery, but it receives its operating power wirelessly from the transmitter / receiver.
  • the RFID transponder preferably has an antenna which serves to receive and transmit signals and to absorb energy.
  • a data storage unit and a converter are preferably provided which is suitable for describing the data storage unit with received data or for reading out the data of the data storage unit and for transmitting it via the antenna.
  • the RFID transponder preferably operates in the UHF range (300 MHz-3GHz) and particularly preferably in the frequency range of 869 MHz. However, RFID transponders in other frequency ranges are also possible.
  • the data storage unit preferably has at least one memory area, which can only be written once, for recording immutable data, such as, for example, serial number and type designation.
  • immutable data such as, for example, serial number and type designation.
  • at least one further data area which can be written on as often as desired is stored, in which variable data such as storage location, company-specific designations, application numbers, etc. are stored.
  • a preferred embodiment of the data storage unit has a first unchangeable data area with the indication of the IPC code, a second unchangeable data area for receiving the unit tag (serial number) and a first recordable data area for acquiring ASCII data.
  • the transmitter / receiver preferably has at least one antenna.
  • Transmitter / receiver solutions known from the prior art have planar antennas. These planar antennas form an effective surface, which must lie at least in part within the geometric straight circular truncated cone described above. This part must preferably be at least 15%, more preferably at least 30%, more preferably at least 66%, and furthermore preferably at least 90% of the effective area. In a planar design of the antenna, this is to be aligned substantially parallel to the end face of the shaft or the axle journal. Small deviations of approx. 5 ° to 25 ° from parallelism are possible.
  • the pressure roller has in particular a pressure cylinder which is mounted by means of a continuous shaft or by means of axle journal.
  • the shaft or the journal carry the impression cylinder both in the bearing device before or after its use, as well as in the transport devices with which it is moved and the rotation bearings of the printing press.
  • This support device may, for example, in an inflatable bellows, which is expanded after pushing the sleeve and this holds it from the inside, or in a single or multi-layer rubber coating to which the sleeve is pushed.
  • the RFID transponder is placed in the shaft or journal. This is preferably done by being inserted in a recess in the surface of the shaft or one of the journal. The recess is then with a suitable material, for example. Epoxy resin, shed or glued so that a smooth finish with the surrounding surface is achieved.
  • the RFID transponder itself can terminate directly on the surface or else be under a protective layer of covering material.
  • a metallic protective layer preferably made of the material of the shaft or of the journal, is preferably glued by means of the material for casting or bonding the RFID transponder.
  • the RFID transponder is not disposed in the region of the shaft or the journal which is subjected to actual bearing or friction forces during operation.
  • the RFID transponder is arranged so that it is in installed state of the pressure roller in the shaft or the journal between the bearing of the shaft or the journal and the end wall of the printing cylinder is located.
  • the RFID transponder is preferably arranged under a metallic or non-metallic protective layer.
  • the non-metallic protective layer is preferably formed of a plastic or ceramic material, more preferably of the material with which the RFID transponder is glued.
  • the achievable read range depends on the installation procedure, in particular how much distance remains between the RFID transponder and the edge of the recess in which the RFID transponder is arranged. This distance is preferably 1 mm to 10 mm, more preferably 2 mm to 7 mm and most preferably 3 mm to 5 mm.
  • the reading or writing the RFID transponder can be done in various ways.
  • a preferred embodiment provides for the use of portable transmitter / receiver devices. These can be used advantageously in particular when the printing cylinders or sleeves are mounted in shelves horizontally resting on the shafts or the journal. An employee can now check the axle ends in their extension in search of a specific pressure roller with a hand-held device until the desired pressure roller is found.
  • An analogous procedure is advantageously also possible if the pressure rollers are installed in the printing press.
  • the geometric axes of the shafts or stub axles point in the direction of the accessible area next to the printing machine. The reading of the RFID transponder data is thus particularly well possible with a portable transmitter / receiver device.
  • the printing press steps off and queries the transmitter / receiver device, for example, the number of previous uses a pressure roller from the RFID transponder to the current order and written back to the RFID transponder.
  • the same can of course be done with stationary on the printing press in the vicinity of the bearings of the shafts or journal arranged transmitter / receiver devices.
  • the pressure rollers are transported individually or to several by means of forklifts.
  • the pressure rollers or sleeves are in the axial direction preferably approximately perpendicular to the transport direction on the Forklift arranged.
  • the forklift truck passes through two parallel transmitter / receiver sets identifying the pressure rollers during transit. If the end of the shafts or journals equipped with the RFID transponder reliably always points in the same direction, a vertical row of transceiver devices may even be advantageously sufficient.
  • Fig. 1 and Fig. 2 show schematic representations of the arrangement according to the invention.
  • Fig. 2 shows the section A from Fig. 1 increased.
  • a pressure roller (1) with a C02509-30AMC RFID transponder (T) integrated in the shaft (13) is used.
  • This RFID transponder (T) transmits in the frequency range of 865.6 - 867.6 MHz.
  • the RFID transponder (T) is arranged in the surface of the shaft (13) and embedded therein in a recess (132) in epoxy resin. Fastening is a shaft portion which is located between the end face (12) of the printing cylinder (11) and the bearing portion in which the shaft (13) rests in the rotary bearing of the printing press.
  • the RFID transponder (T) is read when it passes during transport a stationary RFID transmitter / receiver unit (SE) of the type UHF Longe Range LRU 3000 of the company Feig Electronic.
  • the transmitter / receiver unit (SE) emits a power of about 2 watts and reaches a maximum data transmission range (c) of about 100 cm to 150 cm.
  • the distance (r) between RFID transponder (T) and edge of the recess (132), in which the RFID transponder (T) is arranged, is 3 mm.
  • the stationary RFID transmitter / receiver (SE) is located at the forklift entrance of the storage space in which the pressure rollers (1) store until their use.
  • the pressure rollers (1) Since the transport of the pressure rollers (1) takes place with a custom-made pickup, it is ensured that the pressure rollers (1) the entrance always in the required height and with the correct orientation (shaft end (131) with the RFID transponder (T) in the direction the transmitter / receiver device (SE) oriented) happen. This ensures that the transmitter / receiver unit (SE) is passed within a straight circular truncated cone around the transponder axis (3) at an angle ( ⁇ ) of 20 ° to the latter, the vertex of the angle ( ⁇ ) in the installation location (21). of the RFID transponder on the shaft (13). From the transmitter / receiver unit (SE), the information about the passage of the warehouse entrance is transmitted to a data processing device, which then stores them and / or further processed.
  • a mobile transmitter / receiver unit (SE) - Merlin of the company Nordic ID - with a capacity of 200 mWatt is used.
  • an employee checks the stock at regular intervals or on demand on pressure rollers (1) by stepping off the storage shelves and bringing the mobile transceiver device (SE) close to the end faces of the shaft ends (131), thus interrogating the information.
  • Due to the lower power of the transmitter / receiver device (SE) is here a distance (b) of about 20 cm to successfully read the information from the RFID transponder (T) necessary.
