Definitions

  • the invention relates to a method for detecting and controlling the circulation of multi-use objects, e.g. of reusable containers (bottles) for packaging purposes, in which each item receives a code at the starting point before it goes into circulation, which is recorded and evaluated when it returns to the starting point, and in which the item is coded each time it enters the circulation route again is provided.
  • multi-use objects e.g. of reusable containers (bottles) for packaging purposes
  • the reusable system described above has long been used in a variety of types of packaging containers, such as glass bottles for beer, mineral water and the like. Like. successfully practiced. But other objects, such as crates for receiving and transporting cups, pallets, etc., are in many cases "reusable items" in the above sense.
  • the reusable items have been checked optically, in particular from the point of view of reusability depending on their quality. This happened after the return of the "empties" and before it was fed back into the washing device. The specimens that did not meet the required quality were discarded here, i.e. removed from the "reusable".
  • WO 85/00454 proposes a device for use in the chemical industry.
  • a refillable container for holding different chemicals is to be provided with an additional data memory, which contains data about the previous use of the container, for example about the age, the previous filling liquids, the maximum temperature or impact forces to which the container was previously exposed.
  • the memory or its information is read out via a data reading and evaluation unit and it is checked whether this container is even suitable for the next intended filling process. If this is the case, additional information about the current filling is added to the memory and the filling process is started.
  • the object of the invention is therefore to automate the checking of the reusable objects from the point of view of their reusability depending on their quality, but to keep the costs low.
  • the invention provides that the detection of the coding on the object is carried out by sensors and the recorded signals are compared with those of a stored program, which form criteria for the object to be eliminated from the reusable unit, and that the coding is carried out by microdosing Ink drops are done.
  • the environmentally friendly reusable system can be supported in a simple, cost-effective manner by means of sensory measurement and coding using a coding liquid. There is no need for additional equipment to be provided or attached to the reusable containers themselves.
  • the number of previous rounds can be read in this way, and it can be determined in the course of the evaluation whether the object or the objects are put back into the circulation path or eliminated solely on the basis of their number of rounds want.
  • the invention is explained in the present case with reference to a packaging bottle, although the invention is not restricted to such materials either from the material or the design, the method can be used wherever the reusable concept can realistically take hold.
  • the packaging bottle in question can be a glass bottle or a plastic bottle, in the latter case special consideration being given to so-called “PET bottles”, ie those made from polyethylene terephthalate, which are generally intended as “reusable bottles” are.
  • PET bottles ie those made from polyethylene terephthalate, which are generally intended as “reusable bottles” are.
  • FIG. 1 in FIG. 1 of the drawing denotes the production unit in which the bottle 2, which is practically not tied to a specific shape in terms of its design, is produced ready for filling.
  • the bottle 2 is then fed to a filling station 3 for its filling with filling material, to which a closing station (not shown separately) is expediently connected.
  • a printing and other possibly necessary further decoration of the bottle 2 takes place partly together with the manufacturing process of the bottle 2 and / or after the filling and / or after the closure.
  • the bottle 2 receives a code at 4 before it enters the market, the type of which will be described below.
  • the bottle 2 thus filled and coded reaches, for example, the consumer 6 via the shipping route and sale 5, who returns the bottle after the contents have been emptied (arrow 7).
  • the return is usually made (via the trade) to the bottler.
  • the bottle 2 is detected at 8, in such a way that the coding applied at 4 is first read and identified.
  • bottle 2 passes this check successfully, i.e. If the corresponding quality requirements are still met, the bottle can be returned to the filling and closing system 3 after passing through a corresponding washing device 9. After filling and closing, the bottle receives a new (second) coding at 4 before it enters the second circulation route, for example as described above.
  • the frequency of the reusable circulation for the container 2 depends on the requirements that are placed on the properties of the container.
  • the number of reusable round trips can be e.g. be determined by the coding.
  • the coding on the bottle 2 is sensed in the area of the station 8.
  • the recorded signals are compared with those of a stored program, which form the criteria for the bottle to be rejected.
  • FIG. 7 of the drawing shows in connection with this in the diagram as section A of FIG. 1 such a test arrangement 81 following the (sensor) station 8.
  • the tightness of the container is checked, for example, by pressure test 81 ⁇ , by ultrasonic test 81 ′′ breaks or Cracks in the container and checked by visual inspection 81 ′′′ Surface design, chipping etc. and specimens that did not resist the tests were eliminated at M.
  • the bottles 2 which still meet the quality requirements are fed to the washing device 9 via the path 10, that is to say they remain in the reusable way.
  • Figures 2 to 4 show the coding - here designated 50 - on the container or here the bottle 2, which according to the invention on the bottom ( Figure 2) or on the side wall ( Figures 3, 4) and here, for example, either a circumferential band 22 (FIG. 3) or within a circumferentially limited wall section 24 (FIG. 4).
  • the coding 50 When the coding 50 is arranged on the bottom 2 ⁇ of the bottle 2, different placement variants are conceivable.
  • the coding can thus be arranged radially in the form of a line or a segment. In connection with such a placement the ground register 2 ⁇ has proven to be helpful.
  • the advantage of this arrangement is that the coding does not interfere with the decoration of the container.
  • the coding 50 is provided in the form of a circumferential band 22 on the fuselage wall 21 or at least on a section of said band 22.
  • said band 22 lies below the decor 23.
  • the coding 50 is provided on the fuselage wall 21 within a circumferentially limited wall section 24. This type of placement is preferred for non-round containers.
  • the arrangement of the coding 50 can be incorporated into the overall decor of the container 2 in an advertising-effective manner in conjunction with the recycling concept.
  • FIG. 5 shows a schematic representation of a possibility for applying the coding 50 to container sections in accordance with the representations according to FIGS. 2 to 4.
  • the bottles 2 are guided upright on a conveyor, for example a type of plate belt 11, to a coding device 30.
  • a coding device 30 e.g. lateral guides 12 may be provided in the area of the coding device 30.
  • An essential unit of the coding device 30 is a valve 13 with a connected nozzle 14 for microdosing ink drops, the ink-jet method preferably being used.
  • the valve 13 is actuated via control electronics 15 by the impulse of a light barrier 16 which reports the presence of bottles to be coded.
  • the valve 13 is supplied with coding liquid (ink) from a reservoir 18 via a line 17. While the nozzle 14 is arranged vertically or "overhead" in order to carry out a bottom-side coding 50 of the bottles 2 according to FIG. 2 of the drawing, the dashed-line nozzle 14 ⁇ is horizontally directed towards the fuselage wall of the bottles 2 in order to use a coding 50 corresponding to FIG. 3 or 4. Corresponding additional elements, for example for maintaining the height, the circumferential limitation of the wall section provided for coding 50 (FIG. 4) and the like, the function of which can be controlled by the electronics 15, have been omitted here. As already indicated above, the ink jet method will preferably be used in the context of the coding 50. It has been shown that the use of punctuation marks is particularly favorable, and points of different sizes can also be used in combination with one another.
  • FIG. 6 shows a to f, for example, six different repeatable dot patterns as coding in the sense of the invention.
