Tray sealer, comprising a sealing station for sealing trays, an infeed belt for providing trays, an outfeed belt for transporting sealed trays away, a gripper device comprising a first gripper unit which is configured to pick up trays from the infeed belt and to position them for a sealing process within the sealing station, and comprising a second gripper unit which is configured to collect the trays sealed by way of the sealing station and to position them on the outfeed belt for being transported away, where the first gripper unit comprises a first carriage as well as a first gripper mounted thereon and the second gripper unit comprises a second carriage and a second gripper mounted thereon, a lifting mechanism for opening and closing the sealing station, as well as a control device for controlling a motion of the first carriage and the first gripper as well as for controlling a motion of the second carriage and the second gripper, where, during the opening of the lifting mechanism, the control device is configured to control a closing motion of the second gripper carried out transverse to the direction of production for collecting sealed trays from the sealing station as well as an adjusting motion of the first carriage carried out in the direction of production for supplying unsealed trays into the sealing station such that a substantially predetermined minimum distance is present between the first and the second carriage when the closing motion of the second gripper is at least substantially completed. The disclosure furthermore relates to a method for controlling a gripper device of a tray sealer.

Gripper carriage control

A packaging machine may include a foil transport device and a controlling system for controlling an operation of at least one drive unit of the foil transport device. The controlling system is designed to activate the drive unit during a production run of the packaging machine on the basis of a speed- and/or temperature-dependent friction moment characteristic curve detected by means of a rotationally driven measurement run carried out by the drive unit. The disclosure furthermore relates to a method for controlling a drive unit of a foil transport device.

Sealing device for sealing packages, the sealing device comprising a sealing station with a plurality of receptacles for packages, a transfer belt arranged upstream of the sealing station for transferring packages to the sealing station, a transport belt arranged upstream of the transfer belt for transporting and transferring packages to the transfer belt, and a feeding device for feeding packages to the transport belt, wherein the transport belt and the transfer belt can be driven independently of one another, and wherein the sealing device comprises at least one sensor, which is adapted to determine a distance between successively transported packages in the feeding device, and a control unit, wherein the control unit is adapted to determine a speed profile of the transport belt and a speed profile of the transfer belt based on a distance of successively transported packages measured by the sensor, and to control the transport belt and the transfer belt as a function of the speed profile so that the distance of successive packages during a transfer to the sealing station corresponds to the distance of adjacent receptacles for packages.
