<p>#CMT# #/CMT# The machine has a sealing device (3) that is configured to seal a film (16) onto a tray (17). A matrix monitoring device comprising two monitoring units (14,15) respectively provided at a transverse side and a longitudinal side of the sealing device. The matrix monitoring device is configured to detect one of a misalignment of the tray in a sealing device bottom portion (13) and the presence of foreign matter between the sealing device bottom portion and a sealing device upper portion (12), and to distinguish the foreign matter from a product (18) projecting upwards from the tray. #CMT# : #/CMT# An independent claim is included for a method for operating a tray-sealing machine. #CMT#USE : #/CMT# Tray-sealing machine for use as packaging machine for packaging projecting products. #CMT#ADVANTAGE : #/CMT# The defective sealing or damage to the devices is prevented by detecting the misalignment of the tray in the sealing device bottom portion or foreign matter between the sealing device bottom portion and the sealing device upper portion. The detection of the misalignment of trays and/or foreign matters for the tray sealing machine is improved. The products that project upwards from the tray edge are packed and the errors are detected and addressed. The subsequent comparison with data in the control unit is eliminated. The evaluation time for detecting errors is shortened. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an exploded perspective view of the sealing device. 3 : Sealing device 12 : Sealing device upper portion 13 : Sealing device bottom portion 14,15 : Monitoring units 16 : Film 17 : Tray 18 : Product.</p> |
