Definitions

  • the invention relates to. a method for packaging spatial objects, in particular a spherical praline, in a film-like packaging material, in particular a thin aluminum foil, in that the packaging material is placed in a substantially planar shape over an opening and the object to be packaged is wrapped in the packaging material in such a way that on a Page the packaging material is gathered.
  • the invention further relates to an apparatus for carrying out this method with a device for feeding the packaging material and for placing the same on the opening, with a device for wrapping the article in the packaging material and for gathering the packaging material on one side of the packaged article, and with a device for placing the object in the area of the packaging material.
  • Chocolates are packaged according to a known method DE-C-730766 and with a known device in such a way that pre-cut packaging film sections and the praline are brought one after the other into a treatment station, so that the praline is clamped between two tappets and between a tappet and the praline in the middle Packaging film section is pinched.
  • the initially flat packaging film section is then deformed by the joint movement of the plunger, the chocolate and the packaging film section in a mold cavity such that it is placed around the chocolate. This means that the forming of the initially flat packaging film material is carried out on the praline itself.
  • the praline or another object to be packaged has an uneven, possibly provided with protrusions on the outer surface, there is a risk with this type of packaging that the protrusions will push through the film material and thereby destroy the film material. Of course, this results in an unattractive appearance of the packed praline.
  • the throughput in such a device is limited. If the throughput is increased above a certain limit, the praline is acted on too strongly, so that the special object is not treated with care.
  • the packaging film section is placed on an opening as a flat material.
  • a slat that can be moved radially outwards. tapered cavity is arranged. If the praline lying on the flat packaging film section is pushed downwards, it moves downwards together with the packaging material through the aforementioned cavity, with simultaneous spreading of the above-mentioned lamellae, which press the packaging film material against the praline.
  • this pressing takes place around the entire spherical outer surface of the praline, so that the packaging film material is gathered at the upper end of the packed praline so that it forms a tail-like extension.
  • This tail-like extension is pressed together with a rod, so that there is a small accumulation of material.
  • the packaging film material is molded onto the praline itself, so that the disadvantages already mentioned with regard to damage to the film occur.
  • a particularly gentle treatment of the praline is also not possible with such a packaging method.
  • the throughput can be increased if several such devices are arranged side by side without having to increase the cycle time for each individual praline.
  • the invention has for its object to provide a method and an apparatus of the type mentioned, with which the packaging of a spatial object, in particular a praline, possibly spherical praline, can be carried out so gently that neither the praline nor the packaging material itself is damaged. This should be done with simple means so that a high throughput is ensured with a sufficiently short cycle time.
  • the deformation of the packaging material is largely independent of the object to be packed itself, so that there is far less impairment of the object and the packaging material compared to the prior art, which is particularly advantageous if chocolates and especially with chocolates with an irregular, possibly rough surface should be packed.
  • the packaging material is in its co-operation when preforming tel range, preferably held by a suction force (suction air).
  • suction force suction air
  • the protruding, gathered material forms a tail projecting from the object, which is pressed towards the object, so that a small accumulation of material forms there.
  • the preformed spatial shape of the packaging material is blown out before the final shaping process and, if necessary, after a check, so that no disruptive particles can come to lie between the packaging material and the object.
  • the packaged object is inserted into a receptacle and glued there after an adhesive has previously been applied to the bottom of the receptacle. So that this should advantageously take place with the aforementioned small material accumulation of the packaging material towards the bottom of the receptacle, the packaged object is advantageously automatically turned through 180 ° before it is entered into the receptacle.
  • a device for carrying out the method which is characterized in that at least one molding space forming the opening mentioned, which is almost closed on the side opposite this opening, is provided, and above the opening at least one molding die which can be moved into the molding space is arranged that at least one plunger is arranged below the molding space at a point offset from the molding die, which acts on the one in the molding space.
  • the preformed spatial structure of the packaging material can be moved through the open bottom of the molding space, at least one die being arranged on the side facing away from the plunger above said opening of the molding space, the cavity of which tapers in the direction away from the molding space.
  • a suction channel is preferably arranged in the tappet. which emerges from the front of the same. the preformed packaging material containing the item comes into contact. This ensures that the packaging material cannot slip during the final shaping of the packaging material in the molding die.
  • the attachment of a suction channel in the plunger means a particularly simple solution, since the plunger therefore has a dual function, on the one hand to move the semi-packaged object with the spatial structure of the packaging material in the direction of the molding die and on the other hand to prevent the packaging material from slipping relative to the object. This always ensures that the item can be completely enveloped if the packaging material is optimally tight.
  • a suction channel opens into the cavity of the molding die on the side, which is opposite the side on which the object is inserted into the cavity.
  • a hole is arranged through which a rod can be inserted into the cavity.
  • This rod can be used to compress a tail-like extension of the gathered packaging material, which may form, into a small accumulation of material.
  • a suction channel is arranged in the die for preforming the packaging material, which opens outwards at the end face of the die, with which it initially comes into contact when it acts on the section of the packaging material lying on the opening of the molding space.
  • this suction channel which may be connected to a vacuum source, the center of the flat packaging material section can be held so centrally on the forming die during preforming that the section cannot slip relative to the forming die during the forming. This enables the use of an optimally small, material-saving packaging material section.
  • a multiplicity of mold spaces are expediently arranged transversely to a direction of travel thereof in a carrier element.
  • a plurality of carrier elements in the form of an endless conveyor belt are strung together, so that in the upper run, the working run, the openings of the molding spaces are directed upwards.
  • the individual treatment stations are arranged one behind the other above and / or below the work strand.
  • the treatment station for preforming the packaging material comprises two transverse rows of mold dies arranged one behind the other in the direction of travel of the work strand, which are divided by half the mold dies of a mold row of stamps are arranged offset from each other. As many mold spaces are arranged transversely to the direction of travel thereof in each carrier as there are mold stamps in total in both rows.
  • Each row of form stamps is assigned a device for feeding a film serving as packaging material to the openings of the mold spaces, which devices are equipped with cutting knives arranged one behind the other for longitudinally and transversely cutting the film, the cut, flat film sections of the devices also in the transverse direction to one another lie staggered.
  • This particular type of design of the device has the result that a larger number of mold spaces can be arranged transversely to the direction of travel of the mold spaces with the same width of the system. This would not be possible without this special design, since the initially flat packaging film sections are so large that, due to their size, they would determine a greater distance between the mold spaces transverse to the direction of travel. According to the solution according to the invention, however, in the case of a denser staggering of the mold spaces transverse to the direction of travel, a packaging material is only preformed in every second mold space. The packaging film material is preformed at an advanced position in the intermediate mold spaces.
  • a device for supplying the packaging material in the direction of travel of the mold space carriers is expediently arranged on one side and the other device on the other side of the treatment station for preforming the packaging material. These devices feed the packaging material in mutually directed directions:
  • the two rows of mold stamps can be moved together into the mold spaces of two carriers.
  • the two rows of dies can be moved into the mold spaces of two carriers, which are spaced apart from one another by the width of one carrier.
  • the secondary packaging line B has as its core a further endless conveyor belt 14, which extends transversely to the direction of travel of the endless conveyor belt 10 of the main packaging line A and over which part of the device I is arranged.

  • the device D1 and D2 for feeding and cutting the packaging film material are identical, but work in opposite directions with regard to the feeding of the film material to the device E, whereby it must be taken into account that the operation of the conveyor belt 10 in particular is intermittent, i. H. done gradually.
  • the packaging film material is drawn off from a roll 16 of such a width that the packaging film material can be cut in a row according to this example 7 blanks Z (FIG. 3a), which are arranged next to one another in the direction of travel of the endless conveyor belt 10 and are each intended for packaging a chocolate candy are.
  • the packaging film material V runs over a roll system 18, of which two rolls 20 are arranged on a pivotable lever 22.
  • the lever creates a material supply 24 in the roller system 18, which stores just as much packaging film material as has to be removed for the respective cut. Therefore, the relatively thin film material does not have to be pulled off the heavy roll 16 immediately.
  • Behind the roller system 18 is a pivotable knife carrier 26, on which 6 circular knives 28 are arranged transversely to the direction of travel, which cuts the film into seven longitudinal strips 30 of the same width. Behind the circular knives 28 there is a clamping arm 32 which prevents the film from sliding back when a new supply is formed in the roller system 18.
  • the material supply 24 is pulled off by means of a slide 34 which can be moved back and forth in the direction of the double arrow 38 via a lever linkage 36.
  • a clamping arm 42 controlled by a lever 40 clamps the packaging film material against the carriage 34. This clamping arm 42 moves together with the carriage 34.
  • the carriage 34 moves a sufficient amount of packaging film material in the width required in the direction of travel over a carrier 12 of the endless conveyor belt 10, which is provided with mold spaces 44 arranged in a row transversely to the direction of travel.
  • a transverse cutting device 46 Located in front of this carrier 12 is a transverse cutting device 46, which separates the longitudinal film webs 30 so transversely that almost square blanks Z come to rest centrally over an opening 48 of a molding space 44.
  • the device E for preforming the blanks Z located between these two devices D1 and D2 comprises a crosshead 50 with two rows of shaping dies 52, each row comprising seven shaping dies (of course only for example).
  • the shaping dies of both rows are offset from one another by half a division of the shaping dies transversely to the direction of travel of the endless conveyor belt 10, the shaping dies being assigned to each row of shaping spaces 44 of the carrier 12 in such a way that each shaping stamp of each row is only assigned to every second shaping space 44 of the carrier 12 .
  • each row of dies is assigned to seven of the fourteen mold spaces 44 of the carrier 12 arranged transversely to the direction of travel of the conveyor belt 10.
  • the cut longitudinal strips 30 are preferably offset from one another by half a blank width.
  • the fourteen mold spaces 44 are arranged with their overhead openings 48 so close to each other for space-saving reasons that the size of the blank Z required for packing the praline would cover several openings 48 and thus would interfere with the blanks mutually overlapping during preforming.
  • the first seven blanks are therefore preformed first by means of a row of stamps and then at a later point the remaining seven blanks by the other row of dies, one after the other, although of course the two rows of dies are simultaneously moved into the mold spaces 44 of the carriers 12 by means of the crosshead 50 .
