Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • a device is known from DE-PS 30 44 462.
  • further brakes are required, which means a considerable expenditure of material with the necessary control means, it is not possible to carry out a regulated quick stop in dangerous situations or when necessary.
  • Another disadvantage is the fact that the use of electric or electromagnetic brakes means that the response time is relatively high both during the control process in normal operation and during an emergency stop.
  • the object of the invention is to provide a device for regulating the tension of a print carrier web which, in addition to a compact, inexpensive construction, requires fewer control elements, which reacts faster both in normal operation and when an emergency stop is to be carried out, with which a regulated emergency stop can be carried out and with the addition of only two switching elements, if desired, a quick stop in the event of a power failure and the use of the existing brakes as a residual roller brake for a reel changer is possible.
  • the invention is preferably used in a web-fed rotary printing press in which print carrier webs, for example paper webs, are printed.
  • a roller carrier 1 is usually used, around the bearing 2 of which, preferably two material rollers 4, 5 arranged on a double arm 3, can be positioned.
  • a print carrier web 14 to be regulated is drawn off from one of the rollers, for example from roller 5, and fed to a rotary printing press, not shown.
  • the material rolls 4 and 5 are each rotatably supported on a pair of mandrels or on a roll core 6, 7.
  • a core brake 8 or 9 is arranged on each of the roll cores 6, 7.
  • Each of the core brakes 8, 9 has at least two brake calipers 10, 11 and 12, 13, respectively. It is advantageous to design the brake calipers 11 and 13, which are required for the emergency stop regulated according to the invention, with a higher coefficient of friction than the brake calipers 10 and 12 required for normal operation and / or to provide them twice, as shown.
  • the print carrier web 14 to be controlled is guided over several conventional deflection rollers.
  • a deflectable roller for example a so-called dancer roller 17, is arranged between deflection rollers 15 and 16, the position of which roller is scanned in order to obtain control signals for the web tension.
  • a pneumatic piston 18 is used to preset the web tension or the desired web tension with the aid of a device 20.
  • the pneumatic cylinder 18 allows the dancer roller 17 to move in the direction of the double arrow 19.
  • the deflection of the dancer roller 17 is determined by means of its pivotable arm 21, the upper and lower maximum deflection being limited by stops 22, 23.
  • an electrical sensor 24 is used, which detects the respective angular position of the arm 21. According to the angular position, an electrical signal is given to a control / computing unit 28 via a line 25, which is shown in FIG. 2.
  • this can include, for example, a freely programmable microprocessor.
  • control / computing unit 28 determines control information which is required for normal operation and for a regulated emergency stop. These pass through a line 27 to an electrically controllable air pressure regulator 26, which can also be referred to as an electro-pneumatic converter.
  • the air pressure regulator 26 is supplied with compressed air, for example from a compressor, via an air line 29.
  • the air pressure regulator 26 regulates the air pressure in accordance with the electrical control signals applied to it, so that a proportional pressure change in accordance with the electrical values occurs at an output 30.
  • the minimum air pressure at outlet 30 is preferably at least 0.5 bar.
  • the output 30 is connected to the input of a solenoid valve 31, which is preferably a servo solenoid valve, which is why an additional line 32 pressurized with compressed air is required.
  • a solenoid valve 31 has two compressed air outlets 35 and 35 'on. Corresponding to the control of the solenoid valve 31 by the control / computing unit 28, one of the compressed air outlets 35 or 35 'is acted upon by compressed air.
  • the compressed air outlet 35 leads to a control part 34, which is assigned to the material roll 5 and the corresponding brakes 10, 11, while the line 35 'leads to control parts 34' constructed in the same way and to the brakes 12, 13 for the material roll 4.
  • control part 34 of the circuit in FIG. 2 that is required for the material roll 5 when the web 14 to be regulated is removed from it is described below.
  • the compressed air outlet 35 leads to a further solenoid valve 36 with two compressed air outlets 41 and 43 in the control part 34 for the material roll 5.
  • the previously mentioned control part 34 ' is required for the material roll 4.
  • the solenoid valve 36 is preferably also a servo solenoid valve, a compressed air line 37 is additionally required.
  • One of the compressed air outputs 41 of the solenoid valve 36 is located at an input of a pneumatic OR element 42, while the other compressed air outlet 43 is located at a further OR element 44, the output line 46 of which is connected via the OR element 42 to the brake 10 and directly to the brake 11 for regulated emergency stop .
  • the output of the OR element 42 is connected via a line 47 to the brake 10 for normal operation.
  • either the compressed air outlet 41 or the compressed air outlet 43 is acted upon by regulated compressed air.
  • the compressed air outlet 41 carries compressed air, which reaches the brake 10 for normal operation via the OR element 42, so that sensitive, fast-reacting web tension control is made possible during normal operation.
  • the control / arithmetic unit 28 reverses the solenoid valve 36 so that the compressed air outlet 43, the OR element 44 and the air line 46 can now act directly on the emergency brake 11 for an emergency stop with the regulated compressed air, and in addition the output of the OR element 44 is simultaneously applied to the brake 10 via the OR element 42.
  • a controlled and sensitive emergency stop can thus be carried out via both brakes 10, 11. As a result, the risk of a web break is largely reduced or can be avoided entirely.
  • a servo solenoid valve 38 which is connected to air lines 40 and 39, through which uncontrolled compressed air is supplied, the electr. Voltage and when changing the roll for residual roll braking via line 45 compressed air to the OR element 44 and thus, even if unregulated, in turn to the brakes 10 and 11 at the same time, so that in these situations, albeit uncontrolled, the respective stops or brakes quickly Roll, here the material roll 4 is guaranteed. If there is a voltage from the control / computing unit 28 to the solenoid valve 38, then this is blocked so that the air does not reach the outlet, i.e. arrives at line 45.
  • the solenoid valve 31 is switched over from the control / computing unit 28 via the line 48, so that compressed air reaches the compressed air outlet 35 ′.
