Definitions

  • the present disclosure relates to a packaging machine and method for heating of a film to be deformed.
  • zone heaters can be employed in which the heating plate has been manufactured according to the cavity shape so that different regions of the film are heated differently in order to obtain a uniform wall thickness of the film in the subsequent process.
  • This embodiment is constructively very elaborate and extremely inflexible, because it is linked to the package shape.
  • U.S. Pat. No. 5,280,434, DE 102006045327 and GB 1405753 heating devices are known with which a heating surface has a large number of heater elements which can be controlled individually to be able to generate different temperatures on the individual heater elements.
  • the known embodiments are not suitable for also fitting to a moulding stamp nor to moulding surfaces of a lower part of a mould tool such as side walls and bottom surface in order to generate different temperatures in these regions and thus to be able to positively influence the moulding process.
  • a further disadvantage of the state of the art is a continuously heated heating plate with a simultaneously cooled upper part of the mould tool.
  • the heating plate In order to be able to apply the required heat energy to the film for moulding the film and simultaneously to be able to maintain the general processing times in the deep-draw packaging machine short for a high machine capacity, the heating plate is continuously at the necessary temperature, which is transferred to the film at the moment of feeding or heating the film for an appropriate time in the moulding station.
  • These high temperatures of over 100° C. require cooling of the upper part of the mould tool above the heating plate to provide protection against injuring the operating personnel through burning by touching the relatively freely accessible upper part of the mould tool.
  • This high energy storage in the heating plate also has disadvantages in the heating up phase, for example after a tool change, and in a waiting period before renewed setting up in the region of the moulding station due to the necessity of the heating plate having to cool down.
  • An object of the present disclosure is to provide a device which is suitable for heating a film individually with different temperature levels taking into account in this respect the energy consumption required for the moulding process and eliminating the disadvantages of the state of the art.
  • thick-film heating is taken to mean heating in which the heater elements (without substrate or carrier) have a thickness of at least 1 ⁇ m.
  • the term “heater element” is used synonymously with “heating circuit”.
  • the embodiment of the heating surface according to this disclosure has the advantage that due to the low proportion of material the thick-film heaters can be heated quickly to the required temperature and are able to cool down to the ambient temperature just as quickly, because there is no accumulation of heat. In conjunction with a controller this facilitates a temporally limited switch-on period of the thick-film heater elements during which the film is to be heated, and thus low energy consumption.
  • the plurality of heater elements preferably distributed on the heating surface uniformly or in matrix form, can heat a film individually through the individual control of the heater elements such that different regions or areas of the film can be heated to various levels. This leads to different temperature levels, which can be produced appropriately to the subsequent moulding process in order to obtain the desired wall thicknesses and deformations of the moulded cavity during or after the moulding process.
  • the packaging machine according to the invention presents a solution, which offers a more favourable solution in terms of energy than the state of the art and which ensures increased process reliability and thus attainment of the quality of the packaging cavity.
  • the heating device according to the invention is found to be an economical solution, because no elaborate components have to be made available specially for the moulding process nor set up during a change of product, and because the individually produced temperature levels, which are necessary for the film, can be saved in the controller and recalled. This can lead to the shortest changeover times. Also changes to the different temperature levels are possible via the controller in order to be able to match varying boundary conditions in the moulding process. These boundary conditions may be, for example, shorter operating cycles or varying film thicknesses.
  • the thick-film technology facilitates integration of a plurality of heater elements in a common layer, which can be fitted on a carrier plate and thus be formed as a heating plate.
  • a flat arrangement of this nature can be fitted in an upper part of the mould tool or can preheat the films as a preheater above and/or below the film before the moulding station if the time available in the moulding station is not sufficient.
  • the embodiment as a thick-film heater offers the advantage of cooling the heater elements in the shortest time through cooling in the region of the moulding cavity, for example by means of cooling water channels, such that the heater elements assume the temperature of the cooled moulding cavity or of the lower part of the mould tool and thus this hardly delays the cooling process of the deep-drawn film.
  • the use of the packaging machine according to the invention is particularly practicable in an intermittently operating deep-draw packaging machine, because here the time for an operational cycle, also of the sealing station in the manufacture of packaging under a modified atmosphere, is influenced and in this respect an unwanted dwell time of the film in the moulding station and heating device can occur.
  • the described problem can be avoided by the thick-film heaters which are switched off during this period.
  • the packaging machine according to the invention has a further positive effect during the use and processing of plastic films, which are mostly multi-layered and in line with their properties should therefore be heated very individually for the moulding process in order to be able to obtain the desired results.
  • the methodical sequence according to the invention with an intermittently operating deep-draw packaging machine with at least one heating surface, which has a plurality of preferably uniformly distributed thick-film heaters, whereby a controller can individually control these thick-film heaters, primarily has advantages when heating a film to be deformed to different temperature levels.
  • the moulding station of the deep-draw packaging machine is fed with the film in the form of a strip-shaped material by means of a feed system via gripper chains arranged on both sides. Then the moulding station is closed and a closed chamber is created.
  • the controller can meanwhile, or also only after the closure of the moulding station, control and heat up the heater elements which are realised as thick-film heater elements. This control can be implemented according to a program saved in the memory of the controller or can occur through entries fed into the controller by the operating personnel.
  • the film is preferably drawn onto the heater elements by a negative pressure in the upper part of the mould tool, so that the film is located uniformly on the heater elements.
  • the film heats up accordingly and the desired individual temperature levels arise within the film.
  • the controller switches off the heater elements once the film moulding process starts and the film is deformed into the lower part of the mould tool by means of compressed air in the upper part of the mould tool and/or negative pressure in the lower part of the mould tool.
  • the process is terminated when the film has cooled to a “stable” temperature range in which it is no longer deformable.
  • the moulding station opens and with the removal of the moulded cavities the next section of the film is introduced into the moulding station.

  • FIG. 6 is a schematic view of the moulding station shown in FIG. 2 in closed position in a variant with heater elements on a stamp.
  • FIG. 1 shows a schematic view of a packaging machine 1 according to the disclosure in the form of a deep-draw packaging machine.
  • This deep-draw packaging machine 1 has a moulding station 2 , a sealing station 3 , a transverse cutting device 4 and a longitudinal cutting device 5 which are arranged in this order in the working direction R on a machine frame 6 .
  • a feed roll 7 from which a film 8 is pulled off.
  • a material store 9 is provided from which a lid film 10 is pulled off.
  • a removal device 13 in the form of a conveyor belt is provided with which finished, singled-out packages can be taken away.
  • the packaging machine 1 has a feed device, which is not shown and which grips the film 8 to transport it further in the working direction R during each main operating cycle.
  • the feed device can, for example, be realised using transport chains arranged on both sides.
  • the moulding station 2 is formed as a deep-drawing station with which cavities 14 can be formed in the film 8 by deep drawing.
  • the moulding station 2 can be formed such that several cavities can be formed adjacent to one another in the direction perpendicular to the working direction R.
  • an insertion section 15 is provided in which the cavities 14 formed in the film 8 are filled with the product 16 .
  • the sealing station 3 has a closable chamber 17 in which the atmosphere in the cavities 14 can be replaced, for example, by gas flushing with a replacement gas or with a gas mixture before sealing.
  • the transverse cutting device 4 is formed as a punch which parts the film 8 and the lid film 10 in a direction transverse to the working direction R between adjacent cavities 14 .
  • the transverse cutting device 4 operates such that the film 8 is not parted over the complete width, but rather is not parted at least in a marginal region. This facilitates controlled further transport by the feed device.
  • the longitudinal cutting device 5 is formed as a cutter arrangement with which the film 8 and the lid film 10 are parted between adjacent cavities 14 and on the side edge of the film 8 so that singled-out packages are available behind the longitudinal cutting device 5 .
  • the packaging machine 1 also has a controller 18 . It has the task of controlling and monitoring the processes running in the packaging machine 1 .
  • a display device 19 with the operating elements 20 is used for visualising or influencing the process sequences in the packaging machine 1 for, respectively by, an operator.
  • the film 8 is pulled off the feed roll 7 and transported through the feed device into the moulding station 2 .
  • cavities 14 are formed in the film 8 by deep drawing.
  • the cavities 14 are transported further together with the surrounding region of the film 8 in a main operating cycle to the insertion section 15 in which they are filled with the product 16 .
  • the filled cavities 14 are transported into the sealing station 3 by the feed device in the main operating cycle together with the surrounding region of the film 8 .
  • the lid film 10 is transported further with the feeding movement of the film 8 after a process of sealing onto the film 8 .
  • the lid film 10 is pulled from the material store 9 .
  • FIG. 2 illustrates a moulding station 2 with a preceding preheating station 21 in a variant with a preheater 22 arranged above and also a preheater 23 arranged below.
  • This configuration is practicable primarily with thick films 8 , because the time duration for the heating of the film 8 only in the moulding station 2 is so large that the resulting time of an operational cycle can extend unnecessarily and thus the capacity of the packaging machine 1 can be reduced in terms of the production of packages per minute.
  • the moulding station 2 comprises a lower part of the mould tool 24 with the moulding cavities 25 .
  • the lower part of the mould tool 24 is implemented for movement upwards and downwards via a lifting gear which is not illustrated.
  • the moulding station 2 comprises an upper part of the mould tool 26 in which a heating plate 27 is fitted to the underside.
  • a heating plate 27 is fitted to the underside.
  • On the heating plate 27 a plurality of uniformly distributed heater elements 28 are arranged, implemented as thick-film heating.
  • the individual heater elements 28 can be controlled via the controller 18 , and the visualisation or the adaptation of the individual temperature levels of the heater elements 28 can be realised via the display device 19 .
  • the heating of the film 8 can occur with the moulding station 2 still open, during the closing process or only when the moulding station 2 is closed.
  • FIG. 3 a the lower part of the mould tool 24 has been moved up and now forms a closed chamber 17 with the upper part of the mould tool 26 .
  • the film 8 is clamped all around at the edge by means of a seal 11 and by the lower part of the mould tool 24 and the upper part of the mould tool 26 and is tightly closed.
  • the controller 18 switches the heater elements 28 off and the moulding process starts in the form of deep drawing by overpressure above the film 8 and/or negative pressure below the film 8 .
  • the film 8 initially forms a type of sack due to the pressure difference and the forces acting uniformly on the film 8 .
  • the film 8 has reached the bottom 29 of the moulding cavity 25 and also contacts the moulding cavity 25 in the upper region of the side walls 30 . These surfaces have a very much lower temperature than the film 8 so that here the film 8 is cooled. In order that the film 8 does not cool down below the temperature for the plastic deformation in the moulding time remaining, these regions 29 and 30 of the film 8 are heated to a higher temperature level than the other regions.
  • the film 8 is extended further until the film 8 lies completely in the moulding cavity 25 , as illustrated in FIG. 3 c .
  • the moulding station 2 opens with the lower part of the mould tool 24 moving downwards, as illustrated in FIG. 3 d.
  • FIG. 4 a shows the heating surface of the heating plate 27 with grid or matrix shaped, closely contacting heater elements 28 and four regions 31 to 34 .
  • the graph in FIG. 4 b shows the four different temperature levels 31 ′ to 34 ′ distributed over the heating surface, which arise due to the different temperatures of the heater elements 28 in the regions 31 to 34 .
  • FIG. 5 a variant of the packaging machine 1 according to the present disclosure is shown in which, in addition to the heating surface on the upper part of the mould tool 26 , further heating surfaces 35 and 36 are fitted to the walls and bottom of the moulding cavity 25 .
  • stamp deformation is illustrated in FIG. 6 .
  • the surfaces which are in contact with the film 8 have heater elements 28 fitted which ensure individual temperature levels in these regions.
  • heating surfaces of the packaging machine according to the invention are not restricted to the illustrated embodiments, but rather other combinations or regions can be implemented in the moulding station with heater elements.
  • the film 8 can comprise a plastic film, another thermoformable material or a combination of materials.
  • the packaging machine 1 also comprises a moulding station 2 for a lid film in order to individually heat it and deform it before sealing with the film 8 .
