Definitions

  • the invention relates to a method for wrapping, essentially flat items of goods in the luxury or food industry, in particular chocolate bars or bars, with a packaging film and at the same time shows a device which carries out the method.
  • tube machines have been used for the packaging of all types of packaging goods, in which the packaging film runs off a supply roll in the form of a film web and to which the parts to be wrapped, successively spaced apart, are fed by drivers which are on a sit in the same sense as the film web moving transport element, whereupon the film was wrapped around the respective parts and welded on its longitudinal and transverse edges.
  • the plastic films used are said to be particularly strong and supple because they have to be pulled over a wide variety of molds during processing.
  • the object of the invention is to remedy these deficiencies and to provide a method and a device which allow tube packaging to be carried out, in particular for the inside wrapping of flat articles, such as chocolate bars or bars, a high machine output without special stress on the respective packaging film and economical consumption of packaging material can be achieved.
  • packaging is to be produced in which a longitudinal seal is required on the narrow side and foils, in particular thin and heat-sealable metal foils are used, which cannot be processed over the usual shape shoulders of the conventional tube machines, with a particularly high tightness of the sealing seams is guaranteed.
  • the transport of the film webs is effected by a temporarily direct connection between film web and drivers.
  • the film web is temporarily jammed for the purpose of its transport with the drivers which advance to the enveloping parts.
  • the packaging film web in particular aluminum film, is formed lengthwise into a casing material tube which is U-shaped in cross section, open on one side and accommodating the parts to be wrapped. This is detected and taken along by conveyor belts revolving at approximately the same speed, in that at least one of the two legs of the U-shape and the pieces in between Clamping hose surrounding the entrainer is clamped between the entraining elements and pressure elements acting on the conveyor belts and moving with them and taken along.
  • the packaging film in particular an aluminum film, to be removed from the supply at the same time as the article is handed over and to be bent flat around the row of articles.
  • An apparatus for carrying out this method is characterized in that which is to be wrapped pieces of merchandise and the feed of the Folien ⁇ track a Schlauchschner downstream of the inlet ', the one-shaped U of the running from the supply roll sheet in cross section, the pieces of merchandise herum ⁇ Reaching, laterally open film tube forms, the transport member, running next to the film tube, is provided with drivers which extend from the side into the tube opening and at least on one side of the film tube a pressure device running at the speed of the drivers is provided, which the one side of the hose profile presses on the driver.
  • the tube builder prefferably work together with a pair of conveyor belts, which have a U-shaped film tube on both sides, a moving pressure device being provided on both sides of the film tube, which, under spring force, presses the conveyor belt strand against the film tube presses between the legs of the carrier, which is U-shaped in cross-section and also travels.
  • the film tube is conveyed flat in a U-shape.
  • the pair of conveyor belts is formed from a carrier belt for the film tube and a support belt lying on the top of the film tube. Both the carrier transport and the conveyor belt pair are inevitably driven in order to ensure good conveyance of the free-running conveyor belt or the film tube formed therefrom.
  • 3a to 3c is a schematic representation of the
  • FIG. 3 Side view of a device which carries out the method according to the invention, the line-up of FIGS. 3a-3c forming a single illustration, which is referred to below as FIG. 3 and
  • the pieces of goods to be packaged are supplied on a belt 2 coming from the manufacturing device.
  • confectionery items such as chocolate bars, chocolate bars or the like 1
  • all other, preferably flat, articles from the food industry or cigar or cigarette industry or the like can also be packaged in the same way.
  • the transport of the goods 1 on the feed belt 2 is supported by drivers 3, which are arranged one behind the other on a forcibly driven, operating at the same speed transport organ in the distance adapted to the goods size.
  • the transport member 3 a for the drivers runs next to the conveyor belt, the drivers 3 being held on the transport member 3 so as to be laterally displaceable in holders 3 b.
  • the laterally displaceable drivers extend over the entire width of the article 1 and run next to the conveyor belt 2 at the same speed as this.
  • the packaging film in the present case a heat-sealable aluminum film 5, is pulled off the supply roll 4 with the aid of a conveyor device to be described later.
  • the film strip When entering a tube former, the film strip is laid flat in a U-shape around the articles 1 arriving one behind the other on the feed belt 2, without the need for special molding units.
  • Articles 1 are accepted by the carriers 3 in the
  • CMPI kept apart from each other, which is needed for the later locking process.
  • the articles 1 and the packaging film 5 are moved at the same speed and drawn into the film tube of U-shaped cross section, as can be seen in FIG. 5. Now the film tube 5 with the articles 1 enclosed therein is inserted between a pair of conveyor belts 6, 7 which rotates in the direction of the arrow and is formed from the lower carrier belt 6 and the support belt 7 resting on the top of the film tube 5.
  • Guide rollers 21 are provided for the belt guide in the inlet, of which the upper roller 21, which cooperates with the support belt 7, is acted upon by springs 21a.
  • the drivers 3 extend into the U-cross section of the hose 5, whereby they capture the workpiece 1 to be conveyed in full width.
  • the film tube is transported synchronously with the drivers 3 with the aid of a pressure device 8, 9, 10, 11 and 22, respectively.
  • a pressure device 8, 9, 10, 11 and 22, respectively The mode of operation of such a device can be clearly seen from FIGS. 1 and 2.
  • the pressure devices consist of a conveyor element in the form of a chain or Belt 22, which is equipped with pressure rollers 8 and 9 respectively.
  • a pressure rail 10 In the interior of the conveyor member 22, a pressure rail 10 is provided, which is acted upon by springs 11.
  • the pressure rollers 8 run along the pressure rail 10 and are at the same distance from one another as the drivers 3.
  • the pressure rollers 8 and 9 are pressed firmly against the drivers 3, with the film tube 5 resting against them Run of the band 7 or 6 together with the respective side of the film tube 5 is pressed onto the driver and clamped with it, so that the inevitably moved driver 3 can take along the film tube and the parts forming the pressure device.
  • the packaging film is only slightly stressed by the surface clamping just described, which allows the processing of the thinnest films.
  • the overlap of the film edge beyond the goods 1 can be kept as small as is currently required for the subsequent closing process. This ensures a minimal consumption of film material.
  • the edges of the film tube extending beyond the articles are now welded or sealed to one another by heating rollers.
  • the heating rollers 12, 14 and 13 are swiveled away and can be removed completely from the area of the hot pf-indliehen articles, if necessary, so that there is no radiation on the articles.
  • pairs of rollers are provided in each case, with the pair of heating rollers 12 being followed by cooling roller pairs 13 and 14 for sealing, which permit an optimal tight sealing seam with the most economical material consumption.
  • both the heating rollers and the cooling rollers are connected to heating or cooling devices known per se, which need not be described further here.
  • the film tube 5 with the articles 1 inserted into the division is guided exactly between the support band 6 and the support band 7.
  • the longitudinal sealing seam is made as required on the lower or upper side by means of appropriate folding switches.
  • the film tube 5 with the articles 1 is carried by the guide bands 6 and 7.
  • the drivers 3 which convey the articles and the film tube were previously pulled out of the still unsealed film tube to the side, as indicated in FIG. 4.
  • the method described here and the device operating according to the method can be used for all types of goods packaging, in particular, of course, for those pieces of goods which are temperature-sensitive and therefore have to be packed. This applies in particular to the packaging of foodstuffs, luxury foods, in particular chocolate and confectionery, but also to tobacco products and other goods not belonging to foodstuffs and luxury foods.
