Problems solved by technology

[0003] However, this solution is not suitable for closing trays which are intentionally filled with product protruding upwards beyond the edge of the tray and which The tray should, for example, be encapsulated with a so-called skin foil that lies tightly against the product and the tray
In this case, neither the cameras nor the sensors used to detect the tension of the lid film can reliably distinguish protruding parts of the product from possible foreign objects

Embodiment Construction

[0031] figure 1 An example of a packaging machine 1 is shown which, as in the present example, may be a tray sealing machine. The packaging machine may comprise a frame 2 . The packaging machine 1 can also have a conveyor belt 7 . Furthermore, the packaging machine can also have a packaging station 9 . The filled but not yet encapsulated trays 8 can be transported to the encapsulation station 9 via the conveyor belt 7 . The tray 8 can be moved by means of the gripping device 11 into the sealing station 9 and sealed there by means of a cover film 5 (film) supplied from above, for example by sealing the cover film 5 . For this purpose, the encapsulation station 9 can comprise a sealing tool 10 , which will be described in more detail below. The package completed in this way can be moved from the packaging station 9 to the output belt 15 via the gripping device 11 .

[0032] After the cover film 5 has been sealed, regions of the cover film 5 corresponding to the package or p...

Abstract

The invention relates to a method for detecting an incorrect tool position and a packaging machine. The packaging machine comprises a machine frame having a receiving device for a sealing tool, at least two markings being arranged on the sealing tool, the presence of at least two markings being detected by a sensor of the packaging machine in a first operating position of the sealing tool. The method comprises the steps: acquiring, by a first sensor of the at least two sensors, a first signal indicative of the presence of a first marker of the at least two markers; acquiring, by a second sensor of the at least two sensors, a second signal indicative of the presence of a second marker of the at least two markers; monitoring the first signal and the second signal; acquiring a signal first loss of one of the first signal and the second signal and / or a signal loss of the other one of the first signal and the second signal; and determining that the position of the tool is not correct according to the time difference between the two missing signals or according to the elapsed time length of the first missing signal.

Description

technical field [0001] The invention relates to a packaging machine with a sealing tool and a method for optimizing the operation of the packaging machine. Background technique [0002] A packaging machine with a sealing tool is known, for example, from EP 1 988 024 B1. In order to recognize when the product to be packaged, unsealed packaging trays or foreign objects falling between the tool components may cause damage to the package, the article or the sealing tool, the machine disclosed in this document has a camera or sensor. [0003] However, this solution is not suitable for closing trays that are intentionally filled with products that protrude upwards beyond the edge of the tray and which are to be tightly abutted, for example, on the product and the tray. The so-called skin film (Skinfolie) encapsulation. In this case, neither the cameras nor the sensors used to detect the tension of the lidding film can reliably distinguish protruding parts of the product from po...
