Speed and flexibility are the main challenges for industrial packaging processes, whether the application requires case packers, top-loaders or cardboard box and tray erectors. Whereas previously, a custom-manufactured gripper for each format was used on packaging machines, vacuum end effectors from Schmalz can be flexibly configured and modified, and now this process has been made even faster and more convenient.
Schmalz has recently released new software that allows the user to combine various flanges, connectors and suction pads to create an end effector in just a few clicks. This online configuration software is free at www.schmalz.com/vee: The user simply has to log on, enter the workpiece specifications, the number of suction pads, the suction pad size, and the desired gripper version. Next, the user only has to define the suction pad positions and the connection components such as robot flange plates and the flange module for vacuum feed. All of the components are perfectly coordinated.
"Configuring rather than designing" - that is the principle of this software, which reduces the work required to design a gripper to a minimum: With the VEE configurator, the end effector is created in less than ten minutes. Furthermore, this simple configuration method eliminates design flaws. Changes can be followed step by step using the live preview in 3D view. The 3D model of the gripper can be easily integrated into existing CAD design programs. Immediately after configuration, the user receives an e-mail that includes a parts list in PDF format and the complete CAD files, and can then order the end effector directly via e-mail. Online configuration also reduces manufacturing time by more than 80 percent.
Individually tailored to the application
The modular end effector VEE can be configured with one suction pad (size: 38 x 38 mm, weight: 65 g) all the way to a maximum of twelve suction pads (size: 300 x 200 mm, weight: 500 g). Based on the requirements of their application, the user selects the suction pads they need from Schmalz's highly specialized product range: for handling delicate foil or blister packaging (SGPN series), stable cardboard boxes (SPF), slightly flexible product packaging (SPB1) or filled bags and flow-wrap packaging (SPB4). The VEE can grip loads weighing up to 2000 g regardless of the product type and, with process accelerations of up to 10 g (100 m/s²), it meets the speed requirements for the pick and place processes that are typical for the packaging industry.
A further advantage: the standard quick-change adapter reduces changeover times for the VEE to a minimum. This makes it particularly well-suited to the consumer goods industry. In this field, the trend continues to move towards handling many different kinds of products in smaller and smaller batches, and often a packaging line will only run one type of product for a few hours before the format needs to be changed. Another advantage of the VEE is the hose-free vacuum distribution within the system, which reduces possible leakage and ensures greater efficiency and faster response times.
All VEE elements are made of FDA and BfR-compliant polyphenylsulfone (PPSU). The surfaces of the elements are easy to clean and are resistant to alkaline cleaning agents. This makes them suitable not only for the packaging industry but especially for use in the food processing industry.
