Tray stacker EuroPal RTS – with integrated robot

The robot tray stacker from the EuroPal RTS series from modular automation automates the material flow in production and assembly, and increases the autonomy in your production processes. This is possible because the EuroPal RTS automatically supplies production machines with production parts, or it receives parts from the machines and places them on trays/workpiece carriers. The EuroPal RTS tray stacking machine is available in two sizes, as tray stacker EuroPal RTS43 (workpiece carrier up to 400x300 mm) and tray stacker EuroPal RTS64 (workpiece carrier 600x400 mm).

High flexibility in your production processes, thanks to buffers and increased autonomy

EuroPal RTS from modular automation - robot tray stacker

The EuroPal RTS tray stacking machine takes over the cost-effective supply or removal of workpieces with the aid of trays in automated production plants. It reduces manual work steps and in this way increases cost effectiveness in the production processes. Thanks to its compact construction, it is very space-saving and can be straightforwardly adapted to different machines. The integrated swivelling-arm robot offers additional flexibility and movement in the processes and has the advantage that a larger working radius is covered; it can also take over additional tasks in the automation process in the immediate vicinity of the EuroPal RTS, as it is outside the machine. The main task of the swivelling-arm robot is the unloading and loading of workpiece from or to the tray. During these tasks it operates very precisely and gently.

Thanks to comprehensive knowledge and know-how in the area of control and gripper technology, we can integrate the EuroPal RTS with integrated swivelling-arm robot optimally and seamlessly into your production steps. As a result your production steps become more effective and autonomous, consistently high production quality is ensured and costs are reduced due to the reduction in manual processes.

Automatic supply of production machines with production parts (scenario 1)

Workpiece carriers or stacks of trays filled with production parts are supplied to the robot tray stacker. The workpiece carriers are separated at the unstacking unit and transferred to the handling station via conveyor belt. There the production parts are removed from the tray by the robot and transferred separately to the production machine. The empty workpiece carrier is then transferred via a conveyor belt to the stacking unit were the empty workpiece carriers are stacked again.

Automated removal of production parts from production machines (scenario 2)

Stacks of empty trays are supplied to the robot tray stacker EuroPal RTS. In the first step the trays are separated and then in the second step filled with production parts with the aid of the gripper arm robot. The gripper arm robot receives the production parts from the production machine and places the parts reliably and gently on the workpiece carrier. As soon as the tray is full, it is passed to the third step where the full trays are stacked.
The process of loading and unloading the stacker with trays is manual in both scenarios. This activity is straightforward and does not require the use of any aids thanks to the good accessibility to the machine.

Advantages of the EuroPal RTS tray stackers at a glance:

✔ Space-saving: very space-saving due to the compact construction and the integrated robot (approx. 30-40 % space-saving compared to the competition)
✔ Low-cost due to a modular principle in the machine design – this aspect permits individual solutions at mass production prices
✔ Quality assurance: constant quality at the highest level is ensured due to automated processes.
✔ Cost reduction due to automated processes and constant high quality
✔ High flexibility and adaptation to your requirements: the palletizers can be adapted to different trays and workpiece carriers
✔ Versatile: due to the straightforward configuration can also be used quickly and straightforwardly for other production steps. Can also be used for other process steps with little effort.
✔ Increase in the autonomy due to automated production processes
✔ Can be used for numerous products: for example ideally suited to automotive parts, ball bearings, gear wheels, valves, fan impellers, panels, circuit boards, electrical valves, rotary valves etc.
✔ Interface reducing: thanks to the integrated swivelling-arm robot, you reduce the interfaces in the production process and as a result reduce the effort and the margin for errors.
