Definitions

  • the invention concerns a packaging for a liquid and/or a loose material, which is formed from flat packaging material having fold lines and a marking applied to a wall panel of the packaging.
  • the invention further concerns a blank for the production of such a packaging and a process for the production of a packaging which is made from a moving web.
  • An apparatus for carrying out the process is characterised by special reading devices.
  • Packagings of the kind set forth in the opening part of this specification are known in many different forms and are frequently used for packaging liquid foodstuffs, for example milk or juices which can also contain pieces of fruit.
  • Packagings, blanks for same and also processes for the production thereof are known, in which a web of packaging material is moved through various processing stations and receives fold lines which are used for shaping the material web and forming the packaging.
  • the packaging which is in the process of being produced is filled and closed prior to, upon or after the shaping operation.
  • markings to be printed on packagings and read off photoelectrically in order to control items of equipment in production of the packaging.
  • the known marking comprises a register or bar code and is printed on the packaging with tolerances of ⁇ 1 mm.
  • the intention is to control printing mechanisms so that they also print a piece of decoration in proper register relationship on the surface of the packaging in various colors.
  • a piece of printing is frequently defectively positioned and suffers from a displacement in relation to the web of the packaging material.
  • the bars of the bar code and in particular the transition thereof from black to white can alter, with the consequence that reading and control errors occur.
  • Such changes in the paper mechanism, between the paper mechanism and the filling machine or also in the filling machine are to be detected and used to control the material web so that not only an item of decoration, possibly also of multi-color nature, can be correctly printed in the desired manner on the surface, but also the shaping and folding operations take place at the correct location, including the placement of cuts when separating the filled packagings into individual items.
  • a marking which is applied by printing is admittedly helpful to a great extent but from time to time suffers from the same errors as the errors involved in printing.
  • the invention is based on the notion that the lines of a marking can be formed not necessarily only by printing but in accordance with the invention by stamping.
  • Stamping of the material to produce a pack has essential properties in regard to the quality of the pack. If the stamping is at the correct location on the packaging material or if an item of information about the position of the stamping is passed to the processing machine, the pack can be shaped precisely, it is stable in itself, it is strong and it stands up correctly. In the case of composite material with paper or card as the carrier material, there are packs with corner flaps which have to be folded over at the correct location. That is also effected precisely and easily with correct stamping.
  • the invention therefore takes up the idea of applying the marking by stamping instead of by printing.
  • the operation of reading a printed marking is a further source of error because, as is known, many optical systems are sensitive and represent sources of error.
  • Printed marking also permits measurement only in a linear direction.
  • the object of the invention is to provide a packaging, a blank for same and a process for the production of a packaging, so that the production of the packaging can be implemented more easily, less expensively and with a higher degree of precision.
  • the marking is formed by stamping lines which are disposed in a plane and of which at least two straight stamping lines intersect at least when they are prolonged.
  • the marking is flat or at least substantially so flat as is possible with the known natural substances. It is possible to stamp paper, card, plastic materials and metal foils.
  • the operation of stamping the most widely varying forms of line can be implemented by known tools, for example two oppositely moving rollers of which one has raised portions and the opposite one has recessed portions. It has proven desirable in accordance with the invention that the marking with the stamping lines has at least two straight stamping lines which either already intersect in the marking or which intersect at least when said lines are prolonged or in respect of the prolongation thereof or mathematically (virtually).
  • Such patterns permit rapid precise reading of the marking and contain important items of information which can either be recorded at the entry end of the machine in question and used for the further progress of the web of material, or which are established and used at an upstream machine in order to suitably control the web of material in a downstream-disposed machine.
  • items of information in respect of elongation of the material can be measured after the stamping operation until the discharge from the paper mechanism.
  • the marking has at least one center-symmetrical configurational pattern.
  • Center-symmetrical are all geometrical configurations or patterns which are disposed in one plane and which after rotation through 180° in that plane around a fixed point are in mutually aligned relationship.
  • any line is in center-symmetrical relationship with its center point.
  • Any straight line is center-symmetrical in relation to any point thereon.
  • Any beam is center-symmetrical in relation to its reflected beam.
  • Two straight lines which intersect are center-symmetrical in relation to their apex point. Apex angles are also center-symmetrical configurations.
  • the lozenge or rhombus and rhomboid also constitute center-symmetrical configurations.
  • the invention makes use of the properties of the center-symmetrical configuration for the marking because, by virtue thereof, a large number of important items of information can be read from or derived from the marking, which are useful for controlling the subsequent processing stations.
  • the marking has an outer rectangular frame whose sides in the blank extend parallel to the longitudinal fold lines of the packaging and a parallelogram is inscribed into that outer rectangle (the frame). More especially it is particularly advantageous in that respect in accordance with the invention if in the case of a rhombus as a parallelogram its two diagonals in the blank of the packaging extend parallel to the longitudinal and transverse fold lines of the packaging. In the case of the rhombus the diagonals are in mutually perpendicular relationship. In that case the diagonals bisect the angles of the parallelogram. In accordance with the invention, with a marking applied in that way, more accurate positioning of the packaging material is achieved when producing the packaging.
  • a parallelogram is used as a center-symmetrical configuration in the marking, then that parallelogram describes the kind of pack.
  • the rhombus describes a square pack and the rhomboid describes a rectangular pack.
  • a parallelepipedic pack is cut perpendicularly to its longitudinal center line, in general terms therefore along a horizontal plane, then the cross-section of such a pack along the section line is square or rectangular.
  • Long-life milk is generally packaged in Europe at the present time in rectangular packs while fresh milk is packaged in square packs.
  • the rectangular packaging has in each case two wide side wall panels and therebetween two narrow side wall panels, in respective mutually oppositely disposed relationship.
  • the pack diagonal is an important factor in terms of determining the pack volume.
  • the wide side wall panel is for example of the width B′ and the narrow side wall panel is of the width C′.
  • the repeat length of the pack blank also plays an important part, that is to say the length in the direction of travel of the blanks in the machine. If we have that repeat length on the one hand and the pack diagonal e on the other hand, it is possible to draw conclusions about the pack volume which ultimately is important.
  • the marking with the parallelogram inscribed in the described manner for example a rhomboid
  • the web of the pack blanks moves past at least one stationary sensor in such a way that the sensor beams have an opportunity to scan the marking and read off the values in question. They are compared to reference values which have been previously read in. If the difference is zero then the pack in the process of being formed is in the correct angular position and involves the correct volume and the correct shaping.
  • a second inner rectangle is inscribed in the outer rectangle (the frame) in such a way that two sides coincide with the sides of the outer rectangle, which in the blank extend parallel to the longitudinal fold lines and the other two sides touch the connecting corners of the rhombus in such a way that the corners bisect the sides.
  • the sides of the marking are not bisected by the rhombus.
  • a particular embodiment of the packaging is that which is produced from a material web in which one blank follows after the other.
  • each pack has a longitudinal center line, in relation to which two sides of the outer rectangular frame extend parallel, in the blank. Parts of those two sides coincide with said two sides of the inscribed smaller rectangle. That smaller rectangle is laid around the rhombus in such a way that all four sides of the smaller rectangle coincide with or touch the corners of the rhombus. Therefore the smaller rectangle has been circumscribed around the rhombus.
  • the marking has a mathematical correlation with the packaging blank such that the spacings between points on the marking describe the geometry of the fold lines.
  • the spacings of the transverse sides of the large rectangle perform the task of describing the so-called repeat length of the blank of the packaging, that is to say the pack material length.
  • the blank has longitudinal and transverse fold lines which for example can also be produced by stamping.
  • the repeat length or the length of the pack material is that length which can be measured between two markings which occur in succession in the direction of conveying movement of the blanks in manufacture, at the appropriate location thereof, for each blank carries a marking.
  • the above-mentioned rectangle of the marking therefore provides in encoded form a clear measurement in respect of that repeat length.
  • the same also applies in regard to the height of the smaller inscribed rectangle which for example signifies the width of a narrow side wall panel.
  • the height of the smaller inscribed rectangle which for example signifies the width of a narrow side wall panel.
  • the invention is further characterised in that the stamping lines project in raised relationship at least partly out of the surface of the wall panel and/or are set back in recessed relationship into the surface of the wall panel.
  • the stamping lines project in raised relationship out of the surface of the wall panel. Therefore, when feeling the wall panel of the packaging, they can be felt as portions of increased height. It will be appreciated that they can also be seen with suitable light and shadow.
  • the stamping lines are set back in recessed relationship into the surface of the wall panel, that is to say they are so-to-speak negatively stamped.
  • the marking is produced by forming stamping lines by the process according to the invention, in such a way that the cross-section of the material after the stamping operation is U-shaped and in that respect the thickness of the material remains substantially equal, that provides a highly advantageous signalling possibility.
  • Detectors which scan the marking for different physical properties detect the stamping lines—as viewed in cross-section—by virtue of the stamping line being convex at the surface in question from which it projects in raised relationship—and being concave on the opposite side. Therefore, additional items of information can be provided in a marking which is already quite simple if both positive and also negative stamping of the area of the material web in question is possibly implemented.
  • the stamping lines are already produced when processing the material web in the paper mechanism.
  • the stamping lines can be provided either together with the operation of producing the fold lines for shaping of the packaging, at the same time therewith or also thereafter.
  • fold lines have to be provided in any case and as those fold lines can also be produced for example by stamping, the simplicity of the process according to the invention for producing a marking by stamping is readily apparent.
  • the printing mechanism for applying decoration is disposed in the downstream region of the machine. The marking by means of the stamping lines can therefore be produced beforehand in such a way that the items of information for further processing of the material web or the subsequent blank can be observed and controlled by way of the marking.
  • stamping lines can be sensed, detected and registered mechanically by a sensor or optically or acoustically by a suitable measuring transducer.
  • a structure with an acoustic measuring transducer has been designed in a particularly advantageous manner.
  • the material web is caused to pass through between an ultrasonic transducer and a recording unit arranged at a spacing therefrom.
  • the material web therefore has an ultrasonic beam passing therethrough and damps it. Very accurate results can be very rapidly obtained therefrom.
  • Such ultrasonic measurement is implemented with or without optical measuring transducers. It will be seen that previously known sources of error which occur in particular in connection with optical measurement procedures can be highly advantageously eliminated.
  • the beam in question (an optical beam, an acoustic beam or also a mechanical path of movement) involves all lines of the marking. If the embodiment with the above-described rhombus which is inscribed in the two rectangles is considered, then hitting all lines of a marking with a beam is successful in the particular limit situation where the scanning beam is on the line of symmetry of the marking. That beam therefore extends parallel to the longitudinal center line of the blank, parallel to the long side walls of the large rectangle and centrally therethrough so that it also passes through the connecting corners of the rhombus.
  • two mutually spaced sensors as the reading device according to the invention, whether they involve mechanical sensors or optical or acoustic sensors. When they are active the two sensor beams define a window which permits detection of the optimum amount of items of information from the marking.
  • the marking it is possible for the marking to be produced, read and used for controlling the subsequent steps in a highly effective manner not only in the filling machine but also in the case of using composite material with paper as the carrier material and producing packagings continuously from a tube in the paper mechanism.
  • the paper mechanism it is possible to control the cutting operation, which earlier was only possible after an additional marking had been printed on the material. It is possible to measure the angular orientation of the transported paper web.
  • the paper mechanism it is also possible to detect the connecting seam between two rolls, namely the old empty depleted roll and the fresh roll.
  • the sensors which are arranged stationarily at a spacing from the marking, in the preferred embodiment, scan the marking with at least one and preferably two sensor beams which pass in mutually spaced and parallel relationship over the marking.

If the web of packaging material is passed through a stamping roller and counterpart roller of suitable design configuration, then the packaging material curves between the rollers, forming the stamping lines 25 . If a cross-section were to be laid therethrough, the result would be a U-shape in per se known manner. The thickness of the material remains substantially unchanged in front of and behind the stamping line and even within the stamping line. Therefore a stamping line always projects towards one side of the material web.
