Abstract

The invention relates to a printing machine at least consisting of a rotating reel changer, which receives the paper web to be printed as a roll, and a printing unit, which applies over rotating cylinder rollers inking and fountain solution on the paper web, and a folding unit with rotating folding cylinders for packaging the printed paper web into desired printed products. According to the invention, a transponder is arranged in at least one rotating component of the printing machine and a receiver in a non-moving part of the printing press.

Description

  • The invention relates to a printing machine at least consisting of a rotating reel changer, which receives the paper web to be printed as a roll, and a printing unit, which applies over rotating cylinder rollers inking and fountain solution on the paper web, and a folding unit with rotating folding cylinders for packaging the printed paper web into desired printed products.
  • The correct functioning of a printing machine depends on various parameters. Thus, the machine setting and / or the operating state of a printing press may change in the medium to longer term. Furthermore, due to material parameters, such as paper (quality), dampening solution, printing ink or blankets, short-term fluctuations can occur within the scope of a production.
  • As an example of the machine setting here are not restrictive called the Schmitzringkräfte. Bearer rings are used at the bale ends of the printing cylinder to use in successive rolling cylinders, for example, form transfer cylinder to derive the forces occurring between them in the cylinder contact area in the bearings of the cylinder. This should be improved or reduced by the bearer rings, the (clamping) channel hit suggestions of bending vibrations. The Schmitzring as such is a wearing part, and the Schmitzringkräfte are measured at regular intervals only when the machine is in a very complex manner and possibly reset or the Schmitzring is replaced.
  • Rather pressure-process-relevant operating conditions, such as the temperature in the printing press or in machine components are not determined. Nevertheless, temperature changes are extremely relevant. So, for example by flexing the blankets on the transfer cylinders an unwanted heat input into the transfer cylinder or to these adjacent cylinders take place, which is referred to as a hot spot and has a negative impact on the printing process.
  • Instead, the printing-technical consequences of changes by operators are compensated by manual intervention. Errors often occur because machine parameters are changed without knowledge of the actual cause.
  • So far, especially the most interesting parameters, such as the temperature of rotating machine parts are not detected, since a data transmission of parameters via electrical cables and slip rings in the harsh operating environment of printing presses is not satisfactorily feasible.
  • The inventors have therefore set themselves the task to be able to determine measurement data of a printing press during the printing process.
  • This object is achieved by a printing machine according to claim 1. Further developments of the invention are defined in the dependent claims.
  • The inventors have recognized that it is possible to measure characteristics of interest, such as the Schmitzringkräfte or the temperature in a rotating component during the printing operation, if within this rotating component at least one measuring sensor is arranged, the certain data, such as Schmitzringkraft or Measures temperature and using a built-in rotating component transmitter sends contactlessly to a receiver in the non-moving part of the printing press, from where the data are then further processed in the respective meaningful way.
  • Based on the findings, the inventors propose a printing machine consisting at least of a rotating reel splitter, the the paper web to be printed as a roll, and a printing unit, which applies rotating cylinder rollers ink and fountain solution on the paper web, as well as a folding unit with rotating folding cylinders for converting the printed paper web into desired printed products, to improve to the effect that in at least one rotating component of Printing machine is a transponder and a receiver is arranged in a non-moving part of the printing press.
  • As a result, for example, Schmitzringkräfte and the temperature in cylinders of the printing press can also be measured during the printing operation.
  • In one possible embodiment, the transponder can be firmly integrated in the component of the printing press. In another possible embodiment, the transponder, which as a rule consists of a transmitter and a sensor, can be disassembled in the rotating component.
  • It is advantageous if the transmitter is arranged close to the lateral surface of the rotating component and the sensor between the axis of rotation and the lateral surface of the rotating component. Due to the close arrangement of the transmitter on the lateral surface, a favorable transmission effect can be achieved.
  • The transmitter can be designed as a radio wave transmitter with a transmission wavelength between about 10 0 meters to 10 4 meters. Alternatively or additionally, the transmitter can be designed as a microwave transmitter with a transmission wavelength between about 10 -3 meters to 10 -1 meters. Alternatively or additionally, the transmitter can also be designed as an infrared transmitter with a transmission wavelength between about 10 -6 meters to 10 -4 meters. However, transmitters in the UV range between 320 nm [nm = nanometers] to 380 nm or in the visible spectrum between 380 nm and 750 nm are also suitable.
  • Suitable sensors are, for example, various bridge circuits, resistance measuring sensors, such as Pt-100 elements, strain gauges or piezo elements. In addition to forces such as radial, axial and circumferential forces in the cylinders of the printing press, temperatures and electrical voltages or electric charge states can also be detected. It should be determined with the sensors and pressures and humidities on various component surfaces. The inventors also propose to use at least one microphone as the sensor. Depending on the frequency, a spectrum of an optimally adjusted printing machine is recorded and stored. If this noise spectrum changes during the operation of the printing press, a possible disturbance can be identified on the basis of the change and the frequency. If the sensor is designed as an optical sensor, it can detect contamination in the printing press.
  • It is advantageous if the transmitter has its own energy storage or a power supply device is arranged, which inductively couples energy into the transmitter. As energy storage for the operation of the transponders are conventional batteries, rechargeable batteries or fuel cells, which are installed together with the sensor in the rotating component. Depending on the storage capacity and energy requirements of the transponder, it is possible to enable the energy storage device to be replaced or recharged.
  • Another solution is to couple the energy inductively. In this case, in an embodiment at a small distance of about 0.1 mm to 10 mm, preferably 3 mm to 6 mm, to the rotating member in the same axial position of the transponder, a corresponding electromagnetic coil are located, which at each pass of the transponder transmits energy to an integrated coil, which charges a likewise integrated capacitor until its energy is sufficient for a measuring process together with the transmission of the radio signal.
  • The external coil for coupling in the energy is preferably accommodated in a non-moving machine part of the printing press.
  • The external coil and the radio receiver may be separate units or combined into one unit.
  • The measurement signals obtained in this way can then, depending on their nature, continuously record the machine condition. This allows an evaluation and documentation as well as a direct further processing of the signals with the machine control.
  • When the Schmitzringkräften mentioned above, a warning can be issued by the machine control when exceeding limits, which then enables about the operator of the machine to selectively trigger a readjustment. Here, the readjustment by suitable actuators, such as druch linear actuators, hydraulic or pneumatic cylinders occur.
  • For other measurands, such as the temperatures, the measurement signal can be used directly to influence pressure process manipulated variables via the machine control. Thus, when a certain cylinder temperature is exceeded, a cooling circuit can be activated.
  • With this technology, measuring signals can be acquired with the appropriate sensors at one or any number of positions of a rotating component. Here, several sensors can be combined with an energy input and radio unit.
  • These may generally be sizes that are present in the rotating component itself, but also sizes that result in the contact of the rotating parts with other parts, such as with corresponding rotating parts or with material webs, such as the paper to be printed or already printed.
  • In order to be able to reliably transmit a radio signal to the receiver in the case of the partially rapidly rotating parts and a shielding effect which is likely to occur in printing presses by large, high-powered steel machine parts, synchronization may be necessary in such a way that the radio signal is then sent when the transponder is directly in contact the receiver antenna passes. This can be realized, for example, by sending the signal immediately after a renewed energy transmission in the case of a combined unit of external energy injection and receiver.
  • Alternatively, the transmission time may be such that even at low speed at least one full revolution long is sent.
