Problems solved by technology

[0004] However, in the case of atmospheric exchange (especially if the air in the packaging is optionally vacuumed and replaced by a preset gas mixture), especially when packaging products with loose components on the surface of the product ( e.g. products coated with bread crumbs or herbs), it may happen that individual components are blown out of the packaging and thus the extraction duct in the lower part of the tool is contaminated
Contaminated extraction ducts must be cleaned regularly and cause considerable machine downtime
[0005] Although the above-mentioned extraction ducts are not present in tools specially constructed for removal of gases, loose product components (e.g. bread crumbs, herbs, etc.) are then blown directly into the machine space, thus contaminating the machine area for food packaging

Embodiment Construction

[0033] In all figures, the same parts are provided with the same reference numerals.

[0034] figure 1 The deep-draw packaging machine 1 is shown in a perspective view in intermittent operation. The thermoforming packaging machine 1 includes a forming station 2 , a sealing station 3 , a transverse cutting device 4 and a longitudinal cutting device 5 which are sequentially arranged on a frame 6 along the conveying direction R. As shown in FIG. On the inlet side, the frame 6 is provided with a feed roller 7 from which the base film 8 is pulled out. Furthermore, the deep-draw packaging machine 1 comprises a conveyor chain 11 (in particular, conveyor chains or gripping chains 11 arranged on both sides) which grip the base film 8 and convey the base in the conveying direction R in each main working cycle Membrane advances.

[0035] In the embodiment shown, the forming station 2 is configured as a deep drawing station, in which depressions are formed in the base film 8 by deep dr...

Abstract

The invention relates to a sealing tool (24) for a packaging machine, comprising a tool lower part (25) having at least one centrifugal separator (26a, 26b) for separating a particle-laden gas flow (G). The invention also relates to a method for separating a particle-laden gas flow (G) at a sealing tool (24) of a packaging machine, wherein the particle-laden gas flow (G) is separated by means of a centrifugal separator (26a, 26b) arranged at a tool lower part (25) of the sealing tool (24).

Description

technical field [0001] The present invention relates to a sealing station according to variant 1 for a packaging machine. Furthermore, the invention relates to a method according to claim 13 for separating a particle-laden airflow at a sealing tool of a packaging machine. Background technique [0002] In practice, deep draw packers and tray sealers are used to produce sealed packs. A sealing station can be used at such a machine to seal the provided unsealed deep-drawn recesses or prefabricated tray elements, respectively, with a top film. For this purpose, the sealing station comprises a tool lower part and a tool upper part which can form a hermetically sealable chamber in which, before sealing with the top film dispensed from the top film receiver, deep-drawn in the recesses Or the atmosphere in the tray element can be evacuated and / or can be replaced by a gas mixture by flushing with a gas such as a replacement gas. [0003] For example, EP 3 733 536 A1 discloses a se...
