Definitions

  • the invention relates to a device for monitoring and controlling webs of packaging material or the like.
  • the webs for the detection of material defects, such as cracks, material thickening or the like, are monitored with a first sensor and the relative position with a second sensor.
  • a first sensor is monitored with a first sensor and the relative position with a second sensor.
  • a second sensor is known from EP-A-43 723.
  • packaging material used which is delivered in rolls, has already been checked, it can always happen that either faulty batches are delivered or that web sections are damaged during transport or in the packaging machine. Packaging that consists of such damaged material must of course be discarded.
  • EP-A-43 723 a device which comprises two mutually independent detector stations: one for monitoring material defects, one for monitoring the registration of the web.
  • both detector units are linked to one another by a common control unit in such a way that in the event of an error signal either one of the detector units or the other detector unit is given a control signal to a differential speed control unit. Accordingly, the detector units do not trigger different control processes.
  • the detector unit to determine the Registerhaltigke i t extremely complicated, which occur especially when using transparent packaging material great difficulties in border surveillance.
  • a monitoring and control unit shown in the drawings is particularly suitable in connection with packaging machines, preferably cigarette packing machines.
  • a web 10 continuously running towards the packaging machine or a packaging unit (for example a film apparatus), for example made of a plastic film, is to be scanned in relation to the relative position, errors, etc.
  • the defects include irregularities in the material properties of the web 10 (holes, cracks, undesired thickening), but also transverse adhesive strips 11 for connecting the ends of successive webs 10.
  • the monitoring device consists of or is completely housed in a separate housing 12.
  • This unit which is approximately rectangular or cuboid in the present case, can be completely installed in or on the packaging machine and, if necessary, replaced.
  • the housing 12 forms a slot 13 which is eccentric here and is open at one edge. This gives the housing 12 an essentially U-shaped shape with legs 14 and 15 and a web 16 connecting them to one side.
  • the web 10 runs transversely to extend the housing 12 through the slot 13, preferably in the horizontal plane.
  • the monitoring elements namely optical or photoelectric sensors and display elements and the electronic and electrotechnical devices, are accommodated in the housing 12, which is formed with the slot 13 open on one side.
  • the main carrier of these organs is a U-shaped or with a slot 13 formed board 17. At the edge thereof, namely following the contours, a circumferential transverse wall 18 is formed. This also limits the slot 13 on both sides of the same.
  • top walls 19 are expediently attached, which are part of the closed housing 12.
  • the web 10 is scanned for any material defects by a first monitoring system, which consists of a Transmitter 20 on one side and a receiver 21 on the other side of slot 13 and thus web 10.
  • a test medium is emitted from the transmitter 20, preferably pulsating infrared light, which is received by the receiver 21 after passing through the web 10. Changes in the radiation or light intensity lead to a corresponding evaluation by evaluation electronics arranged downstream of the receiver 21 and possibly to the generation of an error signal.
  • the infrared light is guided in the area of the (upper and lower) transverse wall 18 through a respective plan window 22 and 23 inside the same.
  • An amplifier 24 is connected downstream of the receiver 21
  • a material strip is monitored independently of the web 10, namely a tear strip 25 which is attached (off-center) to the web 10.
  • a tear strip 25 is common in the outer wrapping of packaging, especially in the outer foil wrapping of cigarette packs.
  • the web 10 is provided with imaginary cross dividing lines 26, which are defined by blanks 27 to be separated from the web 10, each for a pack.
  • the tear strip 26 extends over the full length of the blanks 27 and thus over the web 10.
  • Pre-punched tabs 28 are marked at the ends for gripping the tear strip 25 when the packages are opened.
  • the presence and the exact position of the tear strip 25 is monitored by an independent system which consists of a common transmitter 29 and two receivers 30 and 31 which are arranged at a distance from one another.
  • the receivers 30 and 31 are arranged at a distance from one another (for example approx. 1 mm) which is somewhat smaller than the width of the tear strip 25. As a result, when the tear strip 25 is arranged in the normal position, both receivers 30, 31 are through it or covers the light beam. In the event of a deviation from the normal position, one or the other receiver 30, 31 is immediately exposed to infrared light, as a result of which an error signal is triggered and a correction movement with regard to the feeding of the tear strip 25 is initiated.
  • the two monitoring systems 20, 21 on the one hand and 29, 30, 31 on the other hand can be assigned optical display elements 33 and 34, which here protrude from the housing 12 in the region of an end wall 35 thereof. Any errors are made visible (in addition) by the display elements 33, 34.
  • the monitoring system with transmitter 29, receiver 30, and 31 fulfills a double function in the present case.
  • the tear strip 25 is provided with a (color) identifier 36, in the embodiment of FIG. 4 in the area of the grip tab 28.
  • This is used in the present device as an additional monitoring aid, specifically for the exact relative position of the Web 10 to be cut blank 27 with respect to the package to be wrapped (not shown).
  • the (color) identifier 36 is scanned by the transmitter 29 or the receiver 30, 31. The result is evaluated in such a way that, in the event of a determined difference in relation to the relative position, the conveying movement of the web 10 and thus the relative position of the blanks 27 are changed.
  • the sensitivity can be set differently depending on the monitoring target.
  • the connected actuating devices of the packaging machine can be set up and adjusted separately with regard to the speed, the size and the direction of the actuating values.
  • the transmitters generate the infrared light in cycles (2-5 kHz) in order to largely eliminate the influence of extraneous light.
  • the relative position of the organs can be selected so that the receivers 30, 31 are each half covered by the tear strip 25, that is to say deliver about half their possible output.
  • the output values are set in the case of a central tear strip 25 so that they are approximately the same and the output signals still do not report an error. (Threshold value setting depending on the permitted tolerance deviation in the lateral direction).
  • the signals can be evaluated in various ways. If one of the amplifiers 32 or both emits an error signal, this can be passed on to the output as an error via an AND link.
  • each amplifier 32 can emit a different signal, e.g. B. plus voltage on the one hand and minus voltage on the other hand. Both signals are given to a sum amplifier, the output of which is zero when the tear strip 25 is running properly.
  • the permissible deviation of the tear strip 25 from the zero position can be set by means of hysteresis, which can be adjusted with a potentiometer, according to plus and minus values at the output. At the same time, these plus and minus values can be used to readjust the position of the tear strip using a correction actuator.
  • the signals are derived here to separate out the incorrect packs or to stop the packaging machine.
