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 that the use of electrical 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 for this purpose, around whose bearing (2), preferably two material rollers (4, 5) arranged on a double arm (3), are rotatably positioned.
  • the print carrier web (14) to be regulated is drawn off from one of the rollers, for example from the roller (5), and fed to a rotary printing press, not shown.
  • the material rolls (4 and 5) are rotatably mounted on a pair of mandrels or on a roll core (6, 7).
  • a core brake (8 or 9) is arranged on each of the roller cores (6, 7).
  • Each of the core brakes (8, 9) has at least two brake calipers (10, 11 and 12, 13). It is advantageous to use the brake calipers (11 and 13) that are required for the emergency stop regulated according to the invention with a higher coefficient of friction to design as the brake calipers (10 and 12) required for normal operation and / or to provide them twice.
  • 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 the 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 transducer (24) is used for this purpose, which detects the respective angular position of the arm (21).
  • a control / computing unit (28) via a line (25), which is shown in FIG.
  • 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 compressed air coming from a compressor is fed to the air pressure regulator (26) via an air line (29).
  • the air pressure is regulated in accordance with the electrical control signals applied to it, so that a proportional pressure change corresponding to the electrical ones at the outlet (30) Values occurs.
  • the minimum air pressure at the 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.
  • the solenoid valve (31) has two compressed air outlets (35 and 35 ⁇ ).
  • one of the lines (35 or 35 ⁇ ) is pressurized with compressed air.
  • the line (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 ⁇ ) to the control parts (34 ⁇ ) constructed in the same way and to the brakes (12, 13) for the material roll (4).
  • the air line (35) leads to a further solenoid valve (36) with two outlets (41 and 43) in the circuit part (34) for the material roll (5).
  • the solenoid valve (36) is preferably also a servo solenoid valve, a compressed air line (37) is also required.
  • One of the outputs (41) of the solenoid valve (36) is located at an input of a pneumatic OR element (42), while the other output (43) is preferably via a further OR element (44), the output line (46) of which is via the OR element (42) the brake (10) and is directly connected to the brake (11) for regulated emergency stop.
  • the output of the OR element (42) is connected to the brake (10) for normal operation via a line (47).
  • the control signals from the control / computing unit (28) either the air line (41) or the air line (43) with regulated compressed air acted upon.
  • the line (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.
  • control and computing unit (28) reverses the solenoid valve (36) so that the brake (11) for is now directly via the air line (43), the OR element (44) and the air line (46) an emergency stop can be acted upon with the regulated compressed air, and the output of the OR element (44) is simultaneously applied to the brake (10) via the OR element (42).
  • a controlled and thus 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. Tension and when changing the roll for residual roll braking via the line (45) compressed air to the OR link (44) and thus, even if unregulated, again to the brakes (10 and 11) at the same time, so that in these situations, even if unregulated, a quick Stopping or braking the respective roll, here the material roll (4) is guaranteed. If there is a voltage from the control / computing unit (28) to the solenoid valve (38), this is blocked, so that the air does not reach the outlet, i.e. reaches the line (45).
  • the solenoid valve (31) When performing a roll change, the solenoid valve (31) is switched over via the line (48) from the control / computing unit (28), so that compressed air reaches the line (35 ⁇ ).
