Definitions
- the present invention relates to a packaging machine with a thermoforming station, in which flat plastic films can be acted upon by underpressure or overpressure, wherein the underpressure and the overpressure can be produced with the same agent.
- thermoforming stations where it is often necessary to pressurize the plastic film with both a lower and an overpressure.
- two separate pressure medium have been required, which makes these thermoforming relatively expensive and their maintenance consuming.
- the object is achieved with a packaging machine with a thermoforming station, in the plane plastic films can be acted upon with underpressure or overpressure, wherein the underpressure and the overpressure can be generated by the same means.
- the packaging machine has a deep-drawing station, in which a packaging film can be subjected to both underpressure and overpressure.
- the respective pressure is generated by the same means.
- the deep-drawing station preferably has an upper tool and a lower tool, the upper tool being arranged above the plastic film and the lower tool below the plastic film.
- the negative pressure or the overpressure are generated in the region of the lower tool or of the upper tool.
- the film is pressed against the heating plate, so that the heat transfer between the plastic film and the heating means is improved. As a result, the plastic film can be heated much better and faster, then deep-drawn to a packaging tray.
- the deep drawing is also carried out with under and / or overpressure.
- the means for generating the underpressure or the overpressure may be any means familiar to the person skilled in the art with which both overpressure and underpressure can be generated. However, it is preferably a pump, very particularly preferably a claw vacuum pump. In such pumps, two claws rotate in opposite directions in a housing. Due to the special geometric shape of the claws, sucked air is compressed inside the vacuum pump. The air is drawn in via the suction flange, compressed in the compression chamber and then expelled again on the pressure side.
- the pump is connected to one or more containers in which there is under or over pressure. These containers serve as buffer tanks.
- FIG. 1 shows schematically the thermoforming station of a packaging machine.
- this thermoforming station one or more packaging trough (s), for example by deep drawing, are formed in a flat plastic film 1.
- the thermoforming station has an upper tool 3 and a lower tool 2. At least the lower tool is arranged vertically movable. In the lower tool is the negative of the packaging tray to be produced.
- a heating element 4 is arranged to heat the plastic film before deformation to the plasticizing temperature. The skilled person understands that the heating element before the thermoforming station can be arranged.
- a claw vacuum pump for example, the company Busch, DE-79689 Maulberg, arranged with the both negative pressure and pressure in a Studentsettabehalter 8 or negative pressure in a vacuum tank 9 can be generated.
- the valve 15 or the valve 10 are opened.
- the area in which the vacuum prevails is 5 and the area in the overpressure is marked 7.
- Both the vacuum tank 9 and the pressure vessel 8 are connected to the upper tool 3 and the lower tool 2, wherein the respective pressure is usually present only in one of the two tools, ie either negative pressure or positive pressure in the lower or in the upper tool is applied , Accordingly, only one of the valves 13, 14 or 11, 12 is opened.
- an overpressure and / or a negative pressure is generated in the upper tool at the beginning of the deformation in the lower tool.
- the plastic film 1 is pressed against the heating means 4 in order to improve the heat transfer between the plastic film 1 and the heating means 4.
- a negative pressure is generated in the lower tool 2 by means of the pump 6 or with the pressure containers 8, 9 and / or an overpressure is generated in the upper tool, with which the plastic film is then deformed.
- the present invention has the advantage that with the pump 6, both the required lower and the required pressure can be generated.
