L-Rack Solution
systron Automatische L-Bock Lösung für systron Glasbearbeitungsanlagen


The automated L-rack solution is the ideal option for customers who use L-racks from any manufacturer as an internal means of transporting glasses.

Up to 8 L-racks can be buffered in the modular L-rack loading system. These are taken over cyclically by the positioning system and fed to the robot, which loads the systron machine fully automatically. Depending on the product mix, the robot can also operate a second machine face-to-face.


  • Optimal operating process without downtime due to handling, breaks or shift changes
  • Up to 8 hours of production without a machine operator
  • Capacity increase by ~ 30%
  • Increase in quality by minimizing handling

With this solution, the machine operator can either manually remove the products after the visual inspection OR a robot can automatically unload the processed panes OR a rack unloading station can be installed to implement a fully automatic loading and unloading process. All systron machines can be supplied and retrofitted with the automatic L-rack solution.

L-rack loading system

The L-rack loading system consists of several chain hoist modules. These are responsible for the buffering and the continuous supply of the positioning system.

The L-racks are manually latched into the feed system and automatically transported to the robot assembly. A maximum of 8 full L-racks can be transported.


  • Maximum weight: 1500 kg / L-rack
  • Maximum transport speed: 5 m/min

L–rack positioning system

The L-rack positioning system is a horizontal chain hoist.

The available and suitable L-racks are latched into the transport system and automatically transported to the robot assembly.

A maximum of two full L-racks and one empty L-rack can be transported.

Robot loading

The systron machine is loaded by a robot. The robot removes the glass sheets from the L-rack with its vacuum suction cups. They must be placed in the middle of the L-rack.


  • Maximum sheet weight: 190 kg
  • Maximum sheet dimensions: 3500 x 2000 mm
  • Minimum sheet dimensions: 600 x 200 mm
  • Maximum sheet thickness: 12 mm

Plausibility Check

In the continuous process, the dimensions of panes are checked for validity at certain points with a linear measurement axis.

The pane dimensions are determined selectively and compared with a stored DXF file – for rectangles as well as for special shapes.

If there is a discrepancy, the further transport of the pane is stopped and a message is displayed.

Automatic Removal of the Cutouts

Cutouts with snap tabs are removed with the help of vacuum suction cups on a Kuka robot and stored in a definable position.

  • Minimum size of cutouts: 100mm x 150mm
  • Maximum size of cutouts: 1000mm x 1500mm
  • Maximum manipulation weight: 40 kg / cutout

Inspection Zone

Control section for optical inspection of the processed glass pane.

  • Variable conveyor speed up to 30m / min
  • Software implementation of the transport tables and the subsequent systems enables the panes to be transported automatically
  • Indirect LED lighting behind the glass pane enables work-friendly and fatigue-free visual quality control
  • Light intensity and color can be adjusted individually

Additional Operator Terminal

The additional operator terminal is placed at the inlet- or outlet-side. It is an exact mirroring of the respective main system operator terminal and increases the profitability of the machine, since working distances are shortened and operation is simplified.

Order management, tool parameters, system parameters, etc. can be viewed and adjusted if necessary. Safety-relevant functions such as acknowledging a safety area, manual mode and start of an automatic mode are only possible from the main terminal.
