Definitions

• 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.
• the machine setting and / or the operating state of a printing press may change in the medium to longer term.
• material parameters such as paper (quality), dampening solution, printing ink or blankets, short-term fluctuations can occur within the scope of a production.
• the Schmitzring As an example of the machine setting here are not restrictive called the Schmitzring mechanism.
• 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 Schmitzring mechanism are measured at regular intervals only when the machine is in a very complex manner and possibly reset or the Schmitzring is replaced.
• the inventors have therefore set themselves the task to be able to determine measurement data of a printing press during the printing process.
• the inventors have recognized that it is possible to measure characteristics of interest, such as the Schmitzring element 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.
• 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.
• Schmitzring mechanism and the temperature in cylinders of the printing press can also be measured during the printing operation.
• the transponder can be firmly integrated in the component of the printing press.
• the transponder which as a rule consists of a transmitter and a sensor, can be disassembled in the rotating component.
• 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.
• the transmitter can be designed as a microwave transmitter with a transmission wavelength between about 10 -3 meters to 10 -1 meters.
• the transmitter can also be designed as an infrared transmitter with a transmission wavelength between about 10 -6 meters to 10 -4 meters.
• Suitable sensors are, for example, various bridge circuits, resistance measuring sensors, such as Pt-100 elements, strain gauges or piezo elements.
• 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.
• the transmitter has its own energy storage or a power supply device is arranged, which inductively couples energy into the transmitter.
• 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.
• 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.
• 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.
• the readjustment by suitable actuators, such as druch linear actuators, hydraulic or pneumatic cylinders occur.
• the measurement signal can be used directly to influence pressure process manipulated variables via the machine control.
• a cooling circuit can be activated.
• measuring signals can be acquired with the appropriate sensors at one or any number of positions of a rotating component.
• 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.
• 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.
• the transmission time may be such that even at low speed at least one full revolution long is sent.
