The palletising magnet design recently modified by Goudsmit Magnetics in Waalre consists of modules that vary in design. The low-maintenance magnet is suitable for palletising and depalletising cans, aerosols, canisters and glass jars with steel lids. The modular construction offers users, such as integrators, packaging companies, food producers or pharmaceutical companies, a number of choices that save on an extra robot and manpower. For example, a lightweight version, or the choice of a spring suspension unit. This is a spring suspension unit that provides a flexible spring path, prevents product damage and enables correct positioning. The options vacuum system and/or pallet gripper ensure that actions such as removing a pallet, laying down or removing an intermediate sheet between a layer of cans can be performed by one robot. The costs saved by the user ensure a quick return on investment for this new system. The palletizing magnet is shown at the Automatica 2022 in Munich. See film here.

Implementation

The central scissor mechanism consists of two cylinders that ensure an even switch-on and switch-off of the palletising magnet and drive the sheet in one go. This ensures a parallel force distribution, which is not always the case when four cylinders are used. The integrated vacuum system is designed to pick up and process any format and type of intermediate sheet. The parallel switching mechanism guarantees a low-maintenance, trouble-free production process, even when loaded unevenly, for example when picking up an uneven layer. The magnet can be equipped with several pole systems. This makes the field stronger at the surface for light cans or aerosols and deeper for heavier loads, such as filled (canning) cans.

Safety and durability

The palletising magnet is easy to operate with pneumatics and is equipped with sensors for on/off detection. The spring suspension unit makes positioning easy and prevents product damage. In addition, it is equipped with sensors that prevent tilt (canting) and jamming, as well as the robot crashing in case of irregularities. In an automated environment, safety is an important aspect. The use of a permanent magnet means that the load remains on the magnet even when energy is lost. This greatly reduces the chance of unsafe situations and damage. Switching with only an air pressure pulse also makes it a very durable and energy-efficient solution.

Maintenance

The palletising magnet has a long life, is very maintenance friendly and uses little air. Any wear parts are easy to replace. The company supplies the lightweight palletising magnet to various customers worldwide. In some places the system runs continuously for 24 hours a day. Even then maintenance is minimal.
