Abstract

The thermo-forming packaging machine according to one embodiment of the present invention comprises a sealing station, a first forming station for forming trays into a lower film web that is in a first forming plane clamped in the first forming station, and a second forming station for forming lids into an upper film web that is in a second forming plane clamped in the second forming station. The sealing station can be configured to create a sealing seam in a sealing plane. The thermo-forming packaging machine may be characterized in that the first forming plane is provided at least 200 mm below the second forming plane, wherein the first and the second forming planes are at least approximately parallel to each other.

First claim

What is claimed is:

1. Thermo-forming packaging machine comprising:
a first forming station for forming trays into a lower film web, the first forming station being configured to clamp the lower film web in a first forming plane;
a second forming station for forming lids into an upper film web, the second forming station being configured to clamp the upper film web in a second forming plane; and
a sealing station configured for creating a sealing seam in a sealing plane;
a chain guide for intermittently transporting the lower film web, wherein the chain guide between the first forming station and the sealing station has an inclination which is configured to ascend from the first forming station to the sealing station; and
wherein the first forming plane is disposed at least 200 mm below the second forming plane, and wherein the first and the second forming planes are approximately parallel to each other.

2. Thermo-forming packaging machine according to claim 1 , wherein the sealing plane is provided at a height relative to a floor on which the thermo-forming packaging machine is arranged, and wherein the second forming plane is provided approximately at or above the height of the sealing plane.

3. Thermo-forming packaging machine according to claim 1 , wherein the first forming plane is oriented at least approximately parallel to the sealing plane.

4. Thermo-forming packaging machine according to claim 1 , wherein a second forming depth of the second forming station is at least twice that of a first forming depth of the first forming station.

5. Thermo-forming packaging machine according to claim 4 , wherein the first forming depth is up to 20 mm and the second forming depth at least 50 mm.

6. Thermo-forming packaging machine according to claim 5 , wherein the second forming depth at about 80 mm.

7. Thermo-forming packaging machine according to claim 1 , wherein the inclination of the chain guide is provided in a direction of production downstream of a loading stretch.

8. Thermo-forming packaging machine according to claim 1 , wherein a loading stretch for loading products into the trays of the lower film web is provided in a direction of production downstream of the first forming station.

9. Method for operating a thermo-forming packaging machine, the method comprising the steps of:
clamping a lower film web in a first forming plane;
forming a tray into the lower film web in a first forming station;
loading a product into the tray;
clamping an upper film web in a second forming plane;
forming a lid into the upper film web in a second forming station;
moving the tray with the product therein upwardly to the lid by way of an inclined chain guide for the lower film web; and
creating a sealing seam in a sealing plane in a sealing station.

10. Thermo-forming packaging machine comprising:
a first forming station for forming trays into a lower film web, the first forming station being configured to clamp the lower film web in a first forming plane;
a second forming station for forming lids into an upper film web, the second forming station being configured to clamp the upper film web in a second forming plane; and
a sealing station configured for creating a sealing seam in a sealing plane;
wherein the first forming plane is disposed at least 200 mm below the second forming plane, and wherein the first and the second forming planes are approximately parallel to each other; and
wherein the sealing plane is provided at a height relative to a floor on which the thermo-forming packaging machine is arranged, and wherein the second forming plane is provided at a height proximate the height of the sealing plane.

11. Thermo-forming packaging machine according to claim 10 , wherein the second forming plane is provided at the height of the sealing plane.
