Definitions

  • the present invention relates to a method and a device for determining the position of a marking or separating element in a stack of flat products according to the preamble of claims 1 and 8 respectively.
  • a label product machine in which a stack of labels and marking foils arranged therebetween are moved step by step past a stationary light barrier. As each marking film passes the light barrier, the latter triggers the actuation of an ejection element which pushes the marking film somewhat out of the stack. The above marking film activates a separating element which dips into the stack along the marking film and separates the part of the stack located in front of it.
  • the present invention is based on the object of creating a method or device of the type mentioned at the outset which is more time-saving and reliable than the prior art.
  • FIG. 1 a system 1 for the production of packages of labels is shown schematically, based on which the basic structure and operation of such a system is explained below.
  • This system 1 has a punching unit 2, which operates in a known manner using the push-through method.
  • the punching unit 2 has a fixed knife 3 and a plunger 4 which is moved towards and back against the knife 3 by means of a pneumatic or hydraulic drive 5.
  • packages 6 of raw labels are pushed through the knife 3.
  • the packages 6 of raw labels which have a marking element 7, for example a carton, as the bottom layer, are placed on a feed 8 and by means of a Feed element 9 is inserted into the punching space of the punching unit 2 with the plunger 4 withdrawn.
  • the die-cut labels 10 are advanced as a lying stack S along an inclined support table 11. In this stack S, the label packs lie against one another and are separated from one another by the marking elements 7.
  • a detector arrangement 12 arranged below the support table 11 and an ejection element 13 are used to subdivide this stack S into the individual packages 16.
  • the presence of a marking element 7 firmly and triggers an actuation of the ejection element 13, which pushes the marked marking element 7 'upwards somewhat, so that it protrudes over the stack S.
  • a parting knife 14 moves behind the ejected marking element 7 'into the stack S, which moves along the marking element 7 into the stack S and advances the package 16 of labels lying in front of this marking element 7' and thereby takes off from the stack S.
  • This separated label package 16 is then passed through a banding or strapping station 15, in which a band 17 is placed around this package 16.
  • the finished banded packets 18 are routed 19, e.g. a slide or a conveyor belt to the next workstation.
  • FIGS. 2-6 The structure of the detector arrangement 12 and the ejection element 13 will now be described with reference to FIGS. 2-6 and the process of detecting and ejecting the marking elements 7 'explained in more detail.
  • FIGS. 2-5 of the system shown in FIG. 1 only the part lying between the punching knife 3 and the banding station 15 is shown.
  • the detector arrangement 12 and the ejection element 13 are fastened to a common carrier 20.
  • the carrier 20 is connected to a revolving traction element 21 (belts or belts) which is guided over two deflection wheels 22, 23.
  • the deflection wheel 22 is driven by a motor 24, which is preferably a stepper motor.
  • This motor 24 drives the traction element 21 in the direction of arrow A, with the result that the carrier 20 together with the detector arrangement 12 and the ejection element 13 is moved in the direction of arrow B along the underside of the stack S. Seen in this direction of movement B, the detector arrangement 12 is arranged at a specific, fixed distance in front of the ejection element 13.
  • a preferably hydraulic or pneumatic actuating device for the ejection element 13 is also arranged on the carrier 20, but is not shown in FIGS. 2-5. By means of this actuating device, the ejection element 13 is moved up and back in the direction of the arrow E.
  • the detector arrangement 12 is of a known type and consists of a light source and a photodetector. The light emitted by the light source is reflected on the underside of the stack S and received by the photodetector. The detector arrangement 12 responds to the contrasts caused by the different brightness of the Labels and the marking element 7 are conditional. In this way, the detector arrangement 12 detects the presence of a marking element 7 when moving along the underside of the stack S. After a marking element 7 has been ascertained, the carrier 20 is moved further by a distance which corresponds to the distance between the detector arrangement 12 and the ejection element 13, so that the ejection element 13 comes to be exactly below this marking element 7.
  • the carrier 20 with the detector arrangement 12 and the ejection element 13 is in its normal starting position 25.
  • the motor 24 is now started and the carrier 20 is thus moved in the direction of the arrow B.
  • the detector arrangement 12 If the detector arrangement 12 has now reached a position in alignment with a marking element 7, which is indicated by the dash-dotted line 26, the detector arrangement 12 responds to the presence of this marking element 7, with the result that the carrier 20, as mentioned above, still changes the distance between the detector arrangement 12 and the ejection element 13 is moved forward and then stopped.
  • the ejection element 13 aligned with the marking element 7 is now actuated, that is to say shifted upwards. As a result, the marking element 7 is pushed upward so that it protrudes over the top of the stack S.
  • the carrier 20 is moved back into its original starting position 25.
  • the carrier 20, ie the detector arrangement 12 had to travel a distance a that was greater than a critical distance that is represented by the area 27 until it reached its response position 26. Due to shifts in the length of the packets 16, it can happen that the distance to be covered by the detector arrangement 12 up to the response becomes smaller than this critical area 27. Such a situation is shown in FIG. 3, from which it is readily apparent that the path a 'traveled by the detector arrangement 12 is smaller than this critical region 27. The detector arrangement 12 is still able to determine the presence of the next marking element 7 and thus trigger it to be pushed out, as was explained with reference to FIG.
  • the displacement path a of the detector arrangement 12 can again decrease as a result of displacements within the stack S to a value which is smaller than the critical region 27 already mentioned. Such a situation is shown in FIG.
  • the carrier 20 or the detector arrangement 12 has to travel a distance a 'which is smaller than the critical area 27 until a marking element 7 is ascertained.
  • the marking element is the same as explained with reference to FIG 7 still pushed up, but then the carrier 20 is moved back from the active position designated 26 'back to the original starting position 25 shown in FIG.
  • the movement sequence of the carrier 20 and thus the detector arrangement 12 and the ejection element 13 explained with reference to FIGS. 2-5 is shown schematically in FIG.
  • the displacement path b between the normal starting position 25 and the other starting position 25 ' is adjustable and can be matched to the length of the label stack 16.
  • the marking element 7 can be fixed and ejected during a pause in the feed movement of the stack S.
  • the detector arrangement 12 and the ejection element 13 stand still and the detection of a marking element 7 in the stack S when the same moves past the stationary detector arrangement and the likewise stationary ejection element.
  • a more reliable detection of the marking elements 7 is possible, since the relative speed required for this purpose between the stack S and the detector arrangement 12 is independent of the stack feed speed and can therefore be determined detached from it.
  • the detector arrangement 12 responds to brightness contrasts between the labels and the marking elements 7. The stronger this contrast, the better the marking elements 7 can be seen.
  • the detector arrangement 12 or its control (not shown) is now designed such that the sensitivity of the detector arrangement 12 is automatically adapted to the differences in brightness between labels and marking elements 7. This is illustrated by the diagram according to FIG. 7, in which the time t after the start of the search movement of the carrier 20 in the direction of the arrow B and the sensitivity E of the detector arrangement 12 are plotted on the ordinate.
  • the detector arrangement 12 detects the brightness of the labels on the one hand and that of the marking elements 7 on the other.
  • the line 30 denotes the brightness of the labels
  • lines 31 and 32 indicate the brightness of the marking elements 7.
  • Line 31 applies to marking elements 7 which are lighter than the labels
  • line 32 indicates the state when the marking elements 7 are darker than the labels.
  • a detector arrangement 12 in which, like in a light barrier, the light source and the photodetector are arranged on opposite sides with respect to the stack S, as described, for example, in Swiss Patent 657,338.
  • transparent or translucent marking elements e.g. Foils used as described in this CH-PS.
  • the principle explained with reference to FIGS. 2-6 for the detection and ejection of marking or separating elements in a stack can also be used in areas of application other than label processing, wherever it is necessary, in an irregular or irregular sequence in the product stack determine existing elements.
  • the identified and pushed out marking or separating elements can subsequently be removed from the stack on their own or, as described, can be used to initiate separating processes, in which case the separating can then take place precisely at the locations defined by the marking or separating elements.
  • the adjustment of the sensitivity of the detector arrangement 12 explained in connection with FIG. 7 can also be used in embodiments in which the detector arrangement is arranged in a stationary manner and the marking elements are fixed past the detector arrangement during the advancing movement of the stack, such as e.g. is described in the previously mentioned CH-PS 657 338.
