Collating Device for Document Booklets Using Ultrasonic Welding

The patent replaces manual mechanical collation operations with an automated system comprising a picking device with suction cups, a conveying mechanism, and a fixing device. The control unit automatically sequences material sheets by controlling the picking device to pick sheets in the correct order from storage stations and place them on the conveying mechanism, eliminating manual intervention and reducing both time and errors.

The system implements self-service through automatic identification and sequencing. The control unit receives document type information, automatically determines the required sheet sequence, and controls the picking and conveying mechanisms to assemble sheets in the correct order without human intervention, making the system self-regulating for different document types.

The patent implements universality through a standardized modular architecture. Multiple storage stations can hold different material sheet types, and the picking device with可控 suction cups can adapt to various sheet configurations. The control unit receives different document type inputs and automatically adjusts the picking sequence and conveying control, allowing one device to handle diverse document types without requiring separate specialized equipment for each type.

The system employs dynamic adaptability where the control unit can modify the operation sequence based on the selected document type. The picking device can dynamically adjust which storage station to access and in what order, and the conveying mechanism can dynamically control the timing and positioning of sheet transfer, enabling flexible adaptation to different document configurations without physical reconfiguration.

The patent extracts and eliminates the need for separate binding elements by integrating the fixing function directly into the collation process. The fixing device uses suction cups to hold material sheets in place on the conveying mechanism during assembly, and the document body itself serves as the binding structure once assembled, removing the requirement for additional staples, clips, or adhesives that would otherwise be needed to bind the sheets together.

The conveying mechanism acts as an intermediary that not only transports material sheets but also serves as a temporary holding surface during assembly. The fixing device with suction cups provides intermediate fixation during the collation process, allowing sheets to be precisely positioned and secured to each other without requiring permanent binding elements, as the sheets are held in place by the controlled suction force during the assembly operation.
