Abstract: 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 distanc

Abstract: A tray sealing machine comprises a gripper device including first and second tray grippers that operate together to take up trays provided by a feed unit and transport them to a sealing station that is downstream in a production direction. A speed of the first and second tray grippers in the production direction when respectively performing a closing motion from a respective initial position toward a respective closing position can be accelerated such that the speed of the first and second tray grippers in the production direction relative to a belt speed of the feed unit during a predetermined first time interval is slower than the belt speed, and during a subsequent predetermined second time interval until the respective closing position has been reached is greater than the belt speed, so that gripper fingers on the first and second tray grippers immerse into respective position windows located between the trays.

Abstract: A method for operating a packaging machine comprising a work station with an exchangeable tool. A control device may be integrated into the tool. When the tool is in a state of the tool installed into the work station, the control device may regulate a temperature of the tool based on an operating temperature target specification by suitably supplying a heating device integrated into the tool with electrical power. Further, when the tool is in a state removed from the work station, the tool may be connected to an external power supply, and the control device may regulate the temperature of the tool based on a preheating temperature target specification by suitably supplying the heating device with electrical power provided by the external power supply.

Abstract: A method of transferring an article from a first drivable conveyor means to a second drivable conveyor means, the transfer of the article taking place during a synchronous phase in which the first and the second conveyor means have the same common speed as one another at any time. The method is characterized in that, during the synchronous phase, the common speed increases at least sectionwise and/or decreases at least sectionwise. A corresponding conveyor system operable for performing the method of transferring an article from a first drivable conveyor means to a second drivable conveyor means, as well as a packaging plant comprising such a conveyor system.

Abstract: The present disclosure relates to a method of transferring an article from a first drivable conveyor means to a second drivable conveyor means, said transfer of the article taking place during a synchronous phase in which said first and said second conveyor means have the same common speed as one another at any time. The method is characterized in that, during the synchronous phase, the common speed increases at least sectionwise and/or decreases at least sectionwise.
