Definitions
- the invention relates to a power supply for a printing press cylinder according to the preamble of claim 1.
- DE 298 08 098 and DE 298 08 099 are devices for register control known in which a power supply in the form of a in the forme cylinder Battery or an accumulator are arranged.
- the power supply is available a transmitter and evaluation unit in connection, through which the signals are electrical interrogable register pins via radio waves or optical radiation to a rack-mounted receiving device are transferable.
- Rotary transformers and in particular designed as slip ring transmitters are known Device, by means of an electricity supplier arranged in the cylinder can be connected to a fixed power supply (e.g. power supply).
- a disadvantage of such rotary transmitters is that they are on the cylinder or in Cylinder pins require installation space, which is particularly the case with forme or plate cylinders with facilities for the circumference and page register adjustment is not available.
- EP 0 551 976 A1 describes a device for the electrical register interrogation known, in which the signals of the electrically interrogable register pins via am Plate cylinder attached contact surfaces are grinded out. To the on Corresponding contacts are made on cylinders attached to the contact surfaces, these contacts being connected to a circuit evaluating the signals are. These contacts can in particular be attached to a device, which is placed on the cylinder during an automatic plate change (e.g. Pressure roller).
- a disadvantage of such a type of signal derivation or Supply of electricity consumers installed in the cylinder is that for Achieve an exact electrical connection that can be adjusted to the contacts Contact pins must be set exactly. Furthermore, these contact areas also contaminate so that a proper signal line or Power supply is not guaranteed.
- a register control system is known in which a battery / in the cylinder Battery is arranged, by means of the electrical provided with lamps queryable register pins are operable.
- This register control system serves however the control of printing plates / printing forms to be mounted by hand, whereby here the power source by means of a manually operated switch is switched off.
- Such a register control device is from DE 77 28 905 U1 known.
- the object of the present invention is therefore to provide a power supply to develop the preamble of claim 1 such that the power source is loaded only when necessary without manual handling.
- the power supply arranged in the cylinder which is designed as a battery or a rechargeable battery, by means of a switch with the electricity consumer arranged in the cylinder connected is. If the cylinder is moved into a position in which the Cylinder arranged device (electricity consumer) to supply voltage is, an actuator is turned on the cylinder, which the Switch or button activated and thus the power supply with the power consumer combines.
- the power supply is connected to the electricity consumer in the cylinder via a button.
- the power source is only during the operation of the Tasters charged.
- it can in particular be a device for Feed a new printing plate act like this, in particular from DE 43 39 344 C1 is known.
- An embodiment of this known device shows thereby a pressure roller on and off this cylinder with a associated folding bar on which the insertion of a new pressure plate serving insertion aid (guide surface) is attached.
- the insertion aid (Guide surface) is only when inserting a new pressure plate on the cylinder employed, i.e. exactly during the phase in which the electrically interrogable Register pins are to be switched.
- the power source / power supply via a switch with two stable Switching states connected to the electricity consumer within the cylinder is.
- the switch is connected to the cylinder adjustable device (e.g. guide device or pressure roller of a plate changer) actuated, to switch off (disconnect) the power supply from Consumer again the appropriate device to the cylinder and thus the Switch is turned on.
- the cylinder adjustable device e.g. guide device or pressure roller of a plate changer
- a cylinder 1 shown in principle there are two electrically interrogated register pins 2.1, 2.2 arranged. These are, for example electrically isolated from the cylinder 1 or the clamping rail, not shown attached to the beginning of printing, so that these register pins 2.1, 2.2 a register-correct installation of a metallic printing form in the manner of a switch actuation is noticeable.
- the register pins 2.1, 2.2 in the Figure 1 shown as a switch.
- the switching or sensor means of the register pins 2.1, 2.2 are provided with an evaluation device 4 arranged in the cylinder 1 as Power consumers in active connection.
- the evaluation circuit 4 is via a switching device 5 designed as a button with a power supply designed as a battery or rechargeable battery 3 connected.
- the switching device 5 designed as a button is by a to the cylinder 1 and off again from this actuating device 6 enableable.
- Figure 2 shows a part of the cylinder 1 with the arranged in a pit and formed as a button switching element 5.
- the actuator 6 for Pressing the switch 5 (button) is a special area the cylinder 1 on and from this lockable pressure roller 7 with one above arranged insertion surface (insertion aid) 8 for printing plates attached.
- the button 5 is actuated, so that the power supply 3 with the evaluation device 4 is connected.
- the button 5 While pressing the button 5 by the Actuator 6 - insertion surface 8 on the cylinder 1 - are the electrically queryable register pins 2.1, 2.2 active, i.e. this is in contact with a corresponding signal can be taken from a printing plate, not shown.
- the button 5 releases the contacts again, so that the power supply 3 is separated from the evaluation unit 4. The power supply 3 is thus without stress.
