Definitions

  • the invention relates to a web break monitoring device for web-fed rotary printing presses according to the preamble of claim 1.
  • a web breakage monitoring device of this type for web-fed rotary printing presses is known from US 5,156,062 DE 39 39 226 A1 known. It can be placed in the printing press at any convenient location. It is preferably arranged between the last printing unit of the printing press and a dryer for drying the printing web, since a web break most often arises in the dryer.
  • a device for detecting web defects prior to the first printing unit of a web-fed rotary printing press contains sensors which contain a large number of optical fibers and produce a signal dependent on the shading of the light guide beams by the printing path.
  • the invention enables the problem to be solved to increase the functional reliability in a web break monitoring device of the type mentioned.
  • the monitoring device generates a web break signal even if the web tension drops so far for a reason other than a web break that a web edge longitudinal strip disappears from the detection area of the detection device.
  • the monitoring device can therefore be used independently of a web break in general for monitoring the tension of the Betigbahn.
  • FIG. 1 the drawings shown detail of a web-fed rotary printing press schematically shows parts of the last printing unit of several printing units.
  • a plate cylinder 3 an upper blanket cylinder 4 and a lower blanket cylinder 6 of an offset web-fed rotary printing machine are shown, between which the printing web 8 passes during printing operation in the direction of web movement 10.
  • a web-fed rotary printing press may include one or more printing units 2.
  • a web catcher 12 is shown schematically. It can be of any embodiment and serves to clamp in the event of a web break following the fracture point of the Bescherbahn 8 and Tozulenken out of the printing press.
  • the web catcher 12 may, for. B. a catch roller 14 and a contact roller 16 (trolly roller) included.
  • the Bescherbahn 8 runs without jamming between the two rollers 14 and 16 therethrough.
  • the web is pinched between the two rollers 14, 16 and deflected downwardly.
  • the Bescherbahn 8 runs in normal operation after the catcher 12 through a dryer 18 for drying the printing ink.
  • a web break monitoring device 20 comprises at least one web longitudinal strip 22 or 24, preferably for both web longitudinal strips 22 and 24 of the printing web 8 each at least one detection device 26 which is directed transversely to the web plane on the relevant web longitudinal strips 22 and 24 of the printing web 8 for detecting the web longitudinal strip of the printing web under tension 8 under proper printing operation and for generating a web break signal when the web edge longitudinal strips 22, 24 disappears from the detection range of the detection device 26 when the tension of the printing web falls due to a web break.
  • the web break monitoring device 20 contains for at least one, preferably for both web edge longitudinal strips 22 and 24, in each case a pneumatic deflection device 30 arranged close to the detection device 26.
  • the deflection device 30 contains at least one or, according to the preferred embodiment according to the drawings, two close to the detection device 26 of the respective web edge longitudinal strips 22 and 24 directed transversely to the web plane on the web longitudinal edge strips 22 and 24 compressed air nozzles 32 and 34, the compressed air jets 35 and 36 acting transversely to the web plane on the web longitudinal edge strips 22 and 24, at trouble-free operation of the tension the printing path can be overcome, permanent pneumatic Generate deflection force.
  • the compressed air jets 35 and 36 and thus their deflection forces are in the FIGS. 1 .
  • the elements of the detection device 26 and the deflection device 30 that act on the printing web 8 can be arranged anywhere within the printing press and are preferably arranged where breaking (delamination) of the printing web 8 occurs most frequently.
  • the elements of the detection device 26 and the deflection device 30 are preferably between the last printing unit and the dryer 18, in particular preferably between the catcher 12 and the dryer 18 accordingly Fig. 1 arranged. These elements may be attached to a non-rotating part of the web catcher 12 or to the dryer 18 or separately to a stationary element of the printing press.
  • the tension of the printing web 8 drops so far that the printing web 8 is moved out of the detection range of the detection device 26 due to the permanently generated pneumatic deflection force of the compressed air jets 35 and 36.
  • the detection device 26 no longer finds the web edge longitudinal strips 22 or 24 in the detection area, it generates a web break signal (for example an electric or pneumatic or hydraulic) which is generated in Fig. 1 is shown schematically by an arrow 40.
  • the web break signal 40 By the web break signal 40, the printing machine is automatically turned off and the web catcher 12 is activated.
  • the web break signal 40 has the value zero and zero in web-break printing operation is automatically switched to a non-zero value when a web break occurs, z. B. to a positive or negative electrical signal value.
  • the detection device 26 continuously generates a signal which is automatically switched off in the event of a detected web break, so that the signal which has been switched off (zero signal value) is the web break signal 40.
  • a deviating from the value zero signal is constantly generated, which is different in orbit-free printing operation as in a detected web break.
  • the web break signal 40 is turned on when, by dropping the tension of the printing web 8, a web break is detected, all the described embodiments being meant hereby.
  • the Bescherbahn 8 would fall out of the detection range of the detection device 26 at a web break without the pneumatic deflection of the compressed air jets 35 and 36 of the compressed air nozzles 26, but only much later than in the support by the pneumatic deflection.
  • each compressed air nozzle 32 is arranged in front of the detection device 26 and another compressed air nozzle 34 after the detection device 26.
  • the detection device 26 may be implemented in various embodiments, for. B. as a pneumatic or electrical proximity switch which, depending on the distance from the Betikbahn 8 or depending on whether the Betikbahn 8 is in his sensor area or not, generates a defined signal.
  • the detection device 26 may comprise a reflex light barrier which has a light emitter and a light receiver on the same web side.
  • the detection device 26 preferably includes a transmitter 41 on one side of the web and a receiver 42 on the other side of the web for transmitting a detection beam 43 along a rectilinear detection axis 44 which crosses the region of the web edge 22 or 24 and thereby only from the printing web 8 is interrupted when it is under tension.
  • the transmitter 41 and the receiver 42 preferably form a light barrier, preferably an infrared light barrier whose light beam is the detection beam 43.
  • the transmitter 41 (or the receiver 42) is preferably arranged in the web movement direction 10 between the two compressed-air nozzles 32 and 34 and / or in the web transverse direction offset from the compressed-air nozzles 32 and 34.
  • a transmitter 41 such a receiver 42 and the two compressed air nozzles 32 and 34 (or only a compressed air nozzle 32 or 34) may be combined to form a monitoring unit 45 and 46, respectively.
  • a control device 50 which responds to a web speed signal 52 changing with changing web speed of the printing web 8 and, depending on this, in a predetermined ratio reduces the pneumatic deflection force of the compressed air jets 36 acting on the printing web 8 with decreasing web speed and with increasing web speed elevated.
  • the pneumatic deflection force preferably has a predetermined strength at a predetermined line speed.
  • the deflection force can be variable proportionally, disproportionately or less than proportionally or in another mode of operation as a function of the web speed, which in turn may depend on the type of printing press and / or on the material of the printing web 8.
  • the pneumatic deflection force of the compressed air jets 35 and 36 is set according to the invention to a much higher value without the Betikbahn 8 pushed out of the range of detection beams 43 of the detection device 26 than at a lower line speed.
  • This results according to the invention has the advantage that at high web speed, a high pneumatic deflection force of the compressed air jets 35 and 36 acts to push the Betikbahn 8 in the event of a web break quickly out of the detection range of the detection beam 43.
  • the deflection force according to the invention is automatically reduced at lower web speed to such an extent that the deflection force can not push the break-free printing web 8 out of the detection beam 43 of the detection device 26. In both cases, however, in the case of a web break, a very fast deflection of the printing web 8 out of the detection beam 43 of the detection device 26 is achieved.
  • the change in the strength of the pneumatic deflection force is preferably carried out by a corresponding change in pressure of the compressed air, which the nozzles 32, 34 from a compressed air source 54 via a Druckeinstellelement 56, z. B. a pressure regulator or a pressure relief valve, is supplied. Additionally or alternatively, an alternative embodiment is to change the jet direction of the compressed-air nozzles 32 and 34 relative to the printing web 8 in order to change the pneumatic deflection force acting on the printing web.
  • the control of the Druckeinstellelements 56 or the jet direction of the compressed air nozzles 32, 34 takes place automatically by the control device 50.
  • the control device 50 preferably receives the electrical (or pneumatic) web speed signal 52, which is dependent on the web speed of the printing web 8 with regard to its thickness, by a printing machine control device.
  • the printing press control device usually generates a web speed signal dependent on the web speed for other functions of the printing press.
  • the web speed signal 52 could also be generated by a buzzer activated by a cylinder, roller or roller which rotates at the speed of the printing web 8.
  • the detection axis 44 between transmitter 41 and receiver 42 is preferably in accordance with FIGS. 3 and 4 inclined to the web plane of Betikbahn 8 inclined so that one of the two cooperating parts transmitter 41 or receiver 42 of the detection axis 44 of the web-transverse center is farther away than the other part.
  • the one part which z. B. the receiver 42 is arranged laterally outside the width of the Betikbahn 8, so that the Betikbahn 8 can be deflected by the compressed air jets 35, 36 at this one part 42 overcoming disability in the event of a web break.
  • the at least one compressed-air nozzle 32, 34 is or are arranged on the same web side of the printing web 8 at a distance from the Betikbahn 8 as the other part, z. B. the transmitter 41, which is arranged closer to the web transverse center than the relevant one part, z. B. the receiver 42nd
  • FIGS. 3 and 4 one part is the receiver 42 and the other part is the transmitter 41, but these parts could also be interchanged.
  • the blown away from the compressed air jets 35 and 36 web longitudinal edge strips 22, 24 are in the FIGS. 3 and 4 shown in dashed lines, while the Belichbahn 8 is shown in solid lines in the transverse direction in a straight line, as is the case when under normal pressure operation is under tension.
  • the pneumatic deflection of the at least one compressed air jet 35 or 36 preferably the two compressed air jets 35 and 36 set so strong and is the at least one jet of compressed air 35 and 36 so far away from the web longitudinal edge 60 and 62 on the web longitudinal edge strip 22 and 24 directed that the pneumatic deflection force at the suitable for normal printing operation tension of the Betikbahn 8 a extending in the web longitudinal direction trough 64 and 66 in the Betikbahn 8 in the region of the web longitudinal edge strips 22 and 24 generates.
  • the troughs 64 and 66 the web longitudinal edge strips 22 and 24 are stiffened. As a result, a flutter of the paper edges is avoided and thus improves the reliability of the monitoring device.
  • the detection axis 44 and thus also the detection beam 43 such that they intersect the longitudinal web edge strips 22 and 24 respectively in the region of the trough 64 and 66, preferably in the region of the outer trough half and more preferably very close to the longitudinal edge of the web 60 or 62.
  • the web longitudinal edge strip 22 or 24 already comes out of the detection axis 44 and thus also out of the detection beam 43 even with a small deflection by the compressed air jets 35 or 36.
  • the monitoring device thus generates a web break signal 40 very quickly when, in the event of a break in the printing web 8, its tensile stress suddenly decreases.
