Definitions

  • the invention relates to a control device for the position of a movable material web, in particular for an axially displaceable bobbin holder, in which the material web runs from a bobbin carrier, a scanning unit with two sensor holders, one on one side of the material web, in the region of the material web running off the bobbin carrier , are arranged, each having two sensors for transmission and reception, and a servomotor which can be controlled by the sensors is provided for adjusting the position of the material web or the bobbin carrier.
  • DE-B-1 043467 describes a device for the automatic lateral control of fabric webs, wherein an edge control is provided only on one edge of the continuous fabric web, which is equipped with two pairs of transmitters and receivers. These pairs of transmitters and receivers are arranged somewhat offset from one another and accommodated in a common fork which can be pivoted about an axis transversely to the direction of movement of the material web in order to be able to set the response range to a certain extent.
  • only one edge area of the material web can thus be monitored; monitoring and scanning of cracks in the entire width of the material web is neither provided nor possible there.
  • the device described there is not suitable for monitoring the flow of material webs, for example thin-walled packaging material webs for the cigarette industry. It is important that there are any cracks, which also. can occur at a very acute angle to the direction of travel of the material web, in order to be able to take the necessary countermeasures.
  • DE-A-2 429 109 describes an arrangement for monitoring a strip of wrapping material from the tobacco processing industry, electrodes of two capacitors being arranged close to one another at a monitoring point. These capacitors are connected via high-frequency resonant circuits to a mixer with downstream evaluation electronics in order to detect capacitive changes with the aid of beat frequencies.
  • Such an arrangement is, however, hardly suitable for practical needs because of the high-frequency-tight housing required, the complicated measuring probes and the electronics susceptible to faults.
  • the device described there is sensitive to dirt insofar as the zero position of the edge is set using a trimmer and small changes in mass should result in control signals. However, dust deposits over the entire length of the measuring probes will also have an influence and change the sensitivity points of the response data, so that malfunctions in practice are to be feared. Because of the required complex structure, a compact accommodation of the device described there is hardly possible.
  • the present invention is based on the object of improving a control device for the position of a movable material web, in particular for an axially displaceable bobbin holder of the type mentioned, in such a way that automatic alignment of the material web and monitoring of the material web during operation are simple is possible.
  • the sensor brackets each have two outer sensors for scanning the two side edges of the material web, that between the two outer sensors a plurality of further sensors are arranged at a short distance from each other, which are arranged in the region of the material web , and that the scanning unit with the sensor brackets and the sensors mounted thereon can be moved transversely to the material web with respect to the relative position by means of a common actuating gear.
  • the measures according to the invention enable the material web to be automatically aligned even during operation.
  • the measures according to the invention can detect cracks or defects in the material web at an early stage, whereupon the necessary countermeasures can be taken.
  • the bobbin holder shown as a detail in the drawings is preferably used in conjunction with a packaging machine.
  • the bobbin holder is usually arranged in the longitudinal center plane of the packaging machine above it.
  • a base 10 of the machine frame is shown.
  • the bobbin holder is on this or this Eccentric, laterally offset bracket for a bobbin carrier 11 is mounted.
  • the bobbin carrier 11 is used in the usual way to receive a bobbin 12 from a wound web 13 of packaging material, for example from tinfoil.
  • the bobbin support 11 is seated with bearings 14 and 15 rotatably on an axis 16, which is designed here as a hollow axis.
  • the bobbin support 11 formed from two side parts 17 and 18 is held together by a rotatable sleeve 19 which surrounds the axis 16.
  • the (smaller) side part 17 mounted on the free side can be pulled off in the axial direction from the sleeve 19 after loosening a head nut 20 of a known type which is designed in a special way.
  • the bobbin 12 can be replaced or a bobbin 12 can be placed on the empty bobbin holder 11 after pulling off a bobbin core.
  • the side part 18 which is fixedly arranged on the sleeve 19 and thus on the axis 16 is provided with a brake drum 21 which interacts with a movable brake shoe 22.
  • the bobbin carrier 11 can be displaced transversely, namely here in the axial direction.
  • the axis 16 is provided on the side opposite the head nut 20 with an extension in the form of a bearing piece 23.
  • This bearing piece 23, which is designed as a hollow axle, is in turn slidably received in a tubular housing 24 here.
  • the housing 24 is provided on the side facing the bobbin support 11 with a cross-sectional constriction, namely a guide section 25, in which the axle 16 or the bearing piece 23 is slidably guided and is stored.
  • the housing 24 is in turn also axially displaceable - in narrow areas - and correspondingly mounted on the base 10 in a holder 26.
  • the free end of the bearing piece 23 is provided with a collar 27, which serves as a stop to limit the movements.
  • Counter stops 28 and 29 of the housing 24 are provided with elastic pads.
  • a piston 31 is displaceable in the pressure medium cylinder 30 and can be acted upon by compressed air in one or the other direction via connecting pieces 32, 33.
  • the end of a piston rod 34 emerging from the pressure medium cylinder 30 is connected to the bearing piece 23 and thus to the axis 16 in the region of an intermediate wall 35.
  • the axis 16 is non-rotatable in the present case.
  • a longitudinal slot 36 is formed in the area of the bearing piece 23.
  • a nose 37 connected to the housing 24 enters the longitudinal slot 36 and provides a rotation lock.
  • the pressure medium cylinder 30 is also non-rotatably supported by the connecting pieces 32 and 33 which are led out laterally from the housing 24.
  • the bobbin support 11 can also be subjected to fine adjustments in the axial direction. This is done to adjust the running web 13 to an exact relative position. This in turn is monitored by a special scanning unit 38.
  • the aforementioned scanning unit 38 consists of two sensor rods 39 and 40 arranged at a distance from one another. Both are equipped with a number of sensors 41 ... 44, namely one sensor rod with transmitters, for example light sources, and the other rod with receivers , for example photodiodes.
  • Two outer sensors 41 and 42 each serve to scan the side edges of the web 13 with regard to possible misalignments.
  • a further, larger number of sensors 43 and 44 is used to monitor any tears and tears in the web 13. Since the formation of cracks may be at a very acute angle to the direction of travel of the web 13, the large number of sensors is relatively small Distance from each other.
  • the relative position of the scanning unit 38 also attached to the base 10 is adjustable.
  • the sensor rods 39, 40 are mounted on a common carrier 45, which in turn can be displaced against a compression spring 48 via an adjusting screw 46 with an adjusting nut 47.
  • the control signals of the sensors 41 and 42 responsible for the edge scanning can be transmitted to a servomotor 49, which effects a corresponding displacement of the bobbin support 11, specifically via an axial displacement of the housing 24 in the holder 26.
  • the servomotor 49 a direct current motor controlled by a suitable electronic circuit by the sensors 41, 42, drives a spindle 50 directed transversely to the housing 24. This in turn sets a spindle wheel 51 in rotation. With the spindle wheel 51, a union nut 52 rotates, which is mounted in a fixed position, namely on the base 10. An internal thread 53 of the union nut 52 meshes with an external thread 54 on the housing 24. This gear mechanism enables very fine axial adjustments of the bobbin carrier 11.
  • the effect of the sensors 43 and 44 is such that if there is a crack in the web 13 of the Ver packaging material the machine or a part of it is shut down.
