Definitions

  • the present invention relates to an apparatus and a method for filling and closing cartons.
  • folding boxes are passed through a hot glue station, where one or more splices of hot glue are sprayed on closing tabs of the folding boxes.
  • the closing flap provided with adhesive is pressed against a second flap of the folding box until the glue has cooled and has reached its strength.
  • the present invention has for its object to provide an apparatus and a method for filling and closing of cartons, which ensure a clean, cost-effective, space-saving and secure closure of the cartons. This object is solved by the features of claim 1 or of claims 11 and 13.
  • the device for filling and closing folding boxes on a first transport device for transporting cartons also a filling device for filling the conveyed by the first conveyor folding cartons with pharmaceutical products, and a closing device for permanently closing closing tabs filled with the pharmaceutical products cartons
  • the closing device has at least one electromagnetic radiation source for activating at least one adhesive point of an electromagnetically heatable adhesive on at least one closing tab.
  • the at least one electromagnetic radiation source is designed as an induction coil. Alternatively, it can also be designed as a microwave radiator.
  • the at least one electromagnetic radiation source is arranged in the region of the first transport device. This embodiment has the advantage that the closing of the cartons can take place immediately after their filling.
  • the first transport device has at least one lateral guide rail for guiding the folding boxes, in the region of which the at least one electromagnetic radiation source is arranged.
  • the electromagnetic radiation source can be arranged directly adjacent to the closing straps to be closed and even serve for their additional guidance.
  • the first transport device is usually followed by a second transport device for the removal of the folding boxes filled with the pharmaceutical products, which takes over the filled folding boxes from the first transport device.
  • the at least one electromagnetic Radiation source then preferably be arranged in the region of the second transport device.
  • the second transport device preferably has two lateral transport belts for transporting the folding boxes, in the region of which the at least one electromagnetic radiation source is arranged.
  • the electromagnetic radiation source is slightly further away from the closing tabs of the carton to be closed and the electromagnetic radiation must penetrate the lateral conveyor belt. Again, however, results due to the integrative arrangement of the at least one electromagnetic radiation source in the overall system a significant space savings.
  • a plurality of electromagnetic radiation sources is arranged in series.
  • a plurality of electromagnetic radiation sources may be arranged in two parallel spaced rows, between which extends the transport device.
  • the device for filling and closing folding boxes in the region of the first transport device can have an application device for applying a film section, which forms the splice, to at least one closing flap. This eliminates a special treatment of folding carton folding carton manufacturer.
  • the handling of the carton manufacturer is facilitated if the splice is formed by a film section. This film section is easy to apply to the closing tab.
  • the film section is configured on one side self-adhesive. This eliminates the need for an additional adhesive.
  • Fig. 1 to 4 four exemplary embodiments of folding boxes 2 are shown, which can be filled with the device according to the invention or the method according to the invention and firmly closed.
  • cuboid cartons 2 have on one of its open sides on a first closing tab 4, on which a splice 6 of an adhesive is applied.
  • the splice 6 can by a cured adhesive or by a film section 7 (see Fig. 3 ) be formed.
  • This splice 6 is used for secure bonding of the first closing flap 4 with a second closing tab 8 of the carton 2.
  • the connection achieved between the closing tabs 4, 8 is permanent and is irrevocably destroyed when opening the carton 2, so it is not reversible.
  • an identical arrangement of a splice 6 may be provided on a closing tab 4, or it may be provided a plug-in flap, which allows a repeated opening and closing of the carton 2.
  • FIG. 2 and 4 illustrated cartons 2 are shown as folding carton blank, wherein two closure tabs 4 each carton 2 splices 6 of the adhesive are applied, which serve for permanently closing the narrow longitudinal sides of the carton 2. This is a tamper-evident closure achieved.
  • the splices 6 are again formed by film sections 7.
  • the folding boxes 2 in a folding carton manufacturer from a folding box according to Fig. 2 manufactured and usually brought by means of a bonding longitudinal tab 10 in a shape in which the body of the carton 2 forming portions are connected by means of the adhesive tab 10 to a cavity-forming unit, while those on the narrow sides arranged tabs including the closing tabs 4 still protrude outward and are not closed.
  • the bonding to the tab 10 takes place via conventional, curing as quickly as possible adhesive.
  • the partially glued Faltschachtelzuitese be folded in any case in a flat shape.
  • the splices 6 can already be applied to the closing tabs 4 during the folding-box production and harden there. These splices 6 are formed in the illustrated embodiments as longitudinal straight lines, but may also have various other geometries. Alternatively, the splices 6 may be formed by film sections 7.
  • the adhesive from which the splices 6 are produced is a different adhesive from a conventional adhesive (such as used for the tab 10).
  • the adhesive to be used for the splices 6 or the film sections must have the property that they can be heated by the action of electromagnetic radiation and thereby activated.
  • the starting material of this adhesive is usually a thermoplastic, which is modified so that the energy of an electromagnetic field is absorbed and converted into heat energy. Preferably, this is achieved by introducing ferromagnetic particles which are heated by induction. Likewise, microwave-absorbing particles are conceivable.
  • the adhesive composition may contain a polymer, a polymer blend or a reaction resin and crosslinker particles, and should be heatable by means of an electromagnetic field, preferably an alternating electromagnetic field.
  • the crosslinker particles consist of filler particles, which may be metallic, ferromagnetic, ferrimagnetic, superparamagnetic or paramagnetic, and crosslinker units, which are chemically bound to the filler particles. For example, by inductive heating of the crosslinker particles, a chemical reaction between the crosslinker unit and the polymer or the polymer mixture is triggered, resulting in a polymer network.
  • the size of the filler particles is generally less than 200 nm, preferably less than 50 nm.
  • the heat necessary for connecting the closing tabs 4, 8 is preferably generated by hysteresis and eddy current losses in the filler particles or mechanical friction losses due to induced oscillation or rotation of the filler particles when exposed to an electromagnetic alternating field.
  • the heat thus generated leads to a melting of the polymer matrix of the adhesive and thus to a wetting of the surfaces of the closing tabs 4, 8 when the adhesive or the foil sections 7 is heated.
  • the method for activating the adhesive compositions is therefore that the adhesive or the film sections 7 are heated by means of an electromagnetic field, preferably an alternating electromagnetic field, preferably inductively to a temperature at which they are pasty and thus the adhesive connection of the closing tabs 4, 8 can be used.
  • This method has the advantage that the duration of the heating can be limited to a range of a few seconds.
  • the application and precuring of the adhesive to form an adhesive bond or the application of the film sections 7 in an application form is already carried out by the folding carton manufacturer.
  • the release of the adhesive composite ie the softening and activation of the precured hot melt adhesive or the film sections 7 at the splice 6, on the other hand, takes place only after filling the folding boxes 2 with pharmaceutical products 12 (see Fig. 5 and 8th ).
  • the film sections 7 can also be applied only during the filling process in the cartoning machine, as with reference to FIG Fig. 11 will be explained in more detail below.
  • hot-melt adhesive which is solid and non-adhesive at room temperature and turns into a pasty state only when activated from the pre-cured state or the film state.
  • Fig. 5 the standard procedure of filling cartons 4 is shown.
  • the folding boxes 2 are stored in a flat state in a folding box magazine 14.
  • the closing tabs 4, 8 of the folding boxes 2 are opened and extend in the plane of the folding box blank.
  • the flat carton blank is already adhered to itself at a location with conventional adhesive, as discussed above.
  • the flat folding box blanks arrive from the folding box magazine 14 onto a first transport device 16, which in the illustrated embodiment is designed as a folded box transport chain.
  • the folding boxes 2 are unfolded on this first transport device 16 and filled by means of a suitable filling device 18 with the pharmaceutical products 12, preferably blister packs.
  • the first transport device 16 runs here either in clocked operation, but preferably continuously.
  • the filling device 18 must be moved during the filling of the cartons 2 with the first transport device 16.
  • the closing tabs 4, 8 on that narrow longitudinal side of the folding boxes 2, at which the filling does not take place preferably by means of mechanical guides folded inwards to ensure a stop for the pharmaceutical products 12 to be inserted.
  • the first transport device 16 is preferably formed as a link chain on which the cartons 2 are mounted between individual driving elements 20.
  • the closing tabs 4, 8 on the used for filling narrow longitudinal side of the carton 2 in turn folded by means of mechanical guides inward and are thus arrived in their desired end position.
  • the at least one splice 6 can also be applied to the at least one closing flap 4 just before it is folded over, as in FIG Fig. 11 is shown.
  • the filled folding boxes 2 are then usually taken over by a second transport device 22, which transports the folding boxes 2 at a preferably higher speed than the first transport device 16.
  • the takeover of the cartons 2 from the first transport device 17 to the second transport device 22 takes place in the illustrated example by arranged on opposite sides, circulating transport belt 24 of the second transport device 22. These transport belt 24 are aligned to the contact with the through the closing tabs 4, 8 formed narrow longitudinal sides of the cartons 2 and remove them by bilateral adhesion from the first transport device 16.
  • At least one electromagnetic radiation source 26 for activating the electromagnetically heatable adhesive should now be integrated into the device.
  • Fig. 6 a first embodiment of the arrangement of the at least one electromagnetic radiation source 26 is shown.
  • two rows of electromagnetic radiation sources 26 are arranged on both sides of the first transport device 16, preferably adjacent to one another in each row.
  • Each electromagnetic radiation source 26 is preferably activated via a generator 28 for generating an electromagnetic alternating field. It is possible to couple each pair of opposing electromagnetic radiation sources 26, or to simultaneously drive the entire row of electromagnetic radiation sources 26.
  • Each electromagnetic radiation source 26 is preferably an induction coil. An embodiment as a microwave radiator is conceivable.
  • the frequency generated by each electromagnetic radiation source 26 is in the range of 10 kHz to 5 GHz, preferably between 3 MHz and 10 MHz.
  • the power generated is in the range between 100 and 3000 watts, preferably in the range of 600 to 2000 watts.
  • the cartons 2 are guided on the first transport device 16 laterally by means of guide rails 30, which are preferably formed of metal.
  • the at least one electromagnetic radiation source 26 is arranged in the region of the lateral guide rails 30, preferably below the lateral guide rails 30.
  • the electromagnetic radiation source 26 touches the carton 2 even in the region of the splice 6 and also serves for lateral guidance of the carton 2.
  • the at least one electromagnetic radiation source 26 may also be arranged above the first transport device 16.
  • FIG Fig. 9 and 10 A second alternative embodiment of the arrangement of the at least one electromagnetic radiation source 26 is shown in FIG Fig. 9 and 10 shown.
  • the at least one electromagnetic radiation source 26 is arranged in the region of the second transport device 22.
  • a parallel arrangement of two rows of electromagnetic radiation sources 26 offers itself laterally next to the transported folding boxes 2.
  • each electromagnetic radiation source 26 is preferably arranged immediately adjacent to the conveyor belt 24, which includes the cartons 2 laterally.
  • the at least one electromagnetic radiation source 26 can also be arranged above or below the second transport device 22.
  • the device for filling and closing folding boxes in the region of the first transport device 16 may have an application device 32 for applying a film section 7, which forms the splice 6, to at least one closing flap 4.
