Definitions

  • the invention relates to a device according to the preamble of patent claim 1.
  • the scanners used in the previously known devices of this type generally work with "normal” light.
  • the scanning takes place essentially perpendicular to the packaging plane, either with transmitted light or with reflected light.
  • the use of transmitted light is only possible with packages that are still "open", ie before the application of the closure or cover film, which is usually made of aluminum.
  • This variant is particularly disadvantageous because it cannot be ruled out with absolute certainty that tablets may fall out of the wells after scanning or before sealing with the aluminum foil.
  • the reflection light variant usually works satisfactorily with clear transparent cup films, but fails with white-opaque cup films.
  • White-opaque cup foils are increasingly required due to the "child safety" of the pack. Since it is known that such films are more or less transparent to infrared light, attempts have also been made to equip devices of the type described in the preamble of claim 1 with infrared light scanners. The results for the transmitted light variant are good, but this has the disadvantages mentioned above. The reflected light variant has not proven itself for infrared light because of the reflective properties of infrared light, especially if it has to penetrate a white opaque layer, are insufficient.
  • the aim of the invention is to improve a device of the type described in the preamble of claim 1 such that the scanning can be carried out on packs with transparent as well as white-opaque cup films on the closed (finished) pack and in both cases absolutely reliable results delivers.
  • the invention thus makes it possible for the first time to use transmitted light scanning on blister packs sealed by metal foils.
  • FIG. 1 shows a simplified schematic representation of a form packing machine 1 with a film web 2.
  • a scanner combination 3 is arranged on the film web 2, which continuously optoelectrically scans the wells of the blister packs passing through in the direction of the arrow TR and the signals or signal changes thus obtained on the receivers via a multi-core cable 4 outputs to evaluation electronics 5.
  • the electronic evaluation unit 5 controls a switch 7 via a further multi-wire line 6 in accordance with the signals obtained by the scanning forwarded to a cartoning machine (not shown) for packaging in folding boxes.
  • the sampling and evaluation of the sampling signals is described in more detail below.
  • the scanner combination (3, 1) comprises e.g. five or more or fewer elements 10a-10e as required, which are mounted on a carrier running perpendicular to the film web 2.
  • this carrier is formed by two rods 11 running perpendicular to the transport direction TR below the film web 2, on which the scanning elements 10a-10e are threaded with corresponding bores 12 and fixed by means of locking screws 13.
  • the rods 11 are in turn releasably attached to the machine frame (not shown).
  • the blister packs labeled PAK pass through the scanner elements 10a-10e in the direction of the arrow TR.
  • the scanner elements 10a-10e are positioned on the rods such that on the one hand they lie exactly between the tracks 15a-15d of the cups 14a-14d. They can also serve as guides for the film web. To improve the guiding effect, the scanner elements can be equipped with wedge-shaped contact surfaces 16.
  • the inner scanner elements 10b-10d are each equipped with an infrared transmitter 17b-17d and an infrared receiver 18b-18d. On the one hand, these transmitters and receivers are mutually offset on the individual scanning elements and, on the other hand, they are arranged such that the transmitters and receivers are exactly opposite one another in adjacent scanning elements.
  • the two scanner elements 10a and 10e lying on the edge make sense equipped with only one transmitter 17a or receiver 18e.
  • the same scanner elements as inside can also be used and remain unused in the scanning element 10a of the receiver 18a and in the scanning element 10e the transmitter 17c. (Any expansion possible as required for foil webs).
  • the transmitters 17a-17d and the receivers 18b-18e are formed by infrared light emitting diodes and infrared receiving diodes. 4, these diodes are designated by D17a-D17d and D18b-D18e.
  • This circuit diagram also shows: with T a potentiometer, with R1-R8 adjustment resistors and with Vl-V4 amplifier.
  • the light-emitting diodes D17a-D17d are connected to the DC voltage U via the adjusting resistors R1-R4 and the receiving diodes D18b-D18e are connected to the DC voltage Ub via the adjusting resistors R5-R8.
  • the potentiometer T is used to set the luminosity of the infrared light-emitting diodes D17a-D17d. This allows adaptation to the cup film or its infrared transmission.
  • the resistors Rl-R8 are used to adjust the diodes once and to limit the current.
  • the infrared receiving diodes D18b-D18e When not illuminated, the infrared receiving diodes D18b-D18e have a high resistance.
  • the setting can be made so that the voltage at points P1-P4 is approximately 0 volts and the voltage at the amplification outputs Al-A4 is approximately 80% Ub.
  • the infrared receiving diodes D18b-D18e have a low resistance, and the setting can be made so that the signal voltage at points P1-P4 is approximately 80% Ub and that at the amplifier outputs is approximately 0 volts.
  • This device is equipped with an adjustable threshold detector and is able to distinguish impulses with relatively small voltage differences.
  • wells 14a, 14c and 14d which are filled with tablets TAB practically completely interrupt the luminous flux between the transmitting and receiving diodes.
  • Empty bowls (bowl 14b) only weaken the luminous flux to a greater or lesser extent, depending on the infrared transparency of the bowl film. It was found that even with practically all commercially available opaque films, the evaluation logic can be set without difficulty (threshold value) in such a way that it can reliably differentiate between filled and empty wells.
  • the evaluation electronics (5. Fig. 1) has the task of combining the signals of the Nap series which belong to a blister pack into one signal. If a tablet is missing or if a single signal is “bad”, the combination signal is also "bad”. All bad signals go to the counter electronics. This consists of shift registers, with one for each push-through pack row. Machine clock pulses now cycle the bad signal parallel to the strand transport to the reject switch 7. This opens when the "bad blister packs" arrive. Only the single badly filled blister pack is excreted.
  • the scanner elements 10a-10e are as thin as possible transversely to the transport direction TR of the packs PAK, so that the scanner arrangement can also be adapted to packs with very narrow cup spacings.
  • diodes such as the LD 271 A BPX 90 from Siemens
  • the offset arrangement of the diodes has already reduced the width of the scanner to approximately 3.5 mm.
  • the scanner elements can be made of metal, the diodes being fixed in corresponding recesses, for example by gluing, and the elec trical lines are led through holes. It is also possible to cast or inject the scanner elements from plastic and at the same time to incorporate the diodes and lines in a single operation.
