A recently granted patent (Publication Number: US11975879B2) discloses a tray sealer with a unique gripper device designed to efficiently handle trays during the sealing process. The tray sealer includes a sealing station, an infeed belt for providing trays, and an outfeed belt for transporting sealed trays away. The gripper device consists of a first gripper unit to pick up trays from the infeed belt and position them for sealing, and a second gripper unit to collect sealed trays and place them on the outfeed belt. The control device manages the motion of the gripper units, ensuring a predetermined minimum distance between them during operation. This innovative design enhances the efficiency and accuracy of the tray sealing process.

Furthermore, the patent details a method for controlling the gripper device of the tray sealer, emphasizing the coordination between the first and second gripper units to optimize tray handling. The controller plays a crucial role in managing the opening and closing motions of the grippers, ensuring a consistent distance between the carriages for seamless operation. By controlling the acceleration and speed profiles of the gripper units, the tray sealer can achieve a desired tray exchange time, enhancing overall productivity. The incorporation of a distance control device and measuring units further enhances the precision of the tray sealing process, making this patented tray sealer a significant advancement in the packaging industry.
