OFFLOADINGSYSTEM for fronts and extruded goods

The offloading system for fronts or extruded goods uses two robots that are placed at the output of the edge-glueing or processing machines.

The fronts can be stacked at different set-down locations, where the robots can alternatively access three of the set-down locations. This means that in the middle locations, both robots can stack the work pieces in alternation. The extruded goods are placed on a large central storage location.

These robot application can be used irrespective of the manufacturer of the edge processing machines. The machine can process up to 30 fronts and 14 extruded goods per minute.

of tall, wall and base unit sides

In these machines, palletising robots pick orders of diverse unit side types using order lists for later production. The robots work on linear axes that we have developed and can grip any number of stacked side panels.

The entire machine requests the necessary inlet stack from logistics via the higher-level control. After the stack of side panels is transferred to the supply transport system, they are then placed fully automatically on the corresponding roller conveyors for the robots to use. This is done by means of diverse transports and integrated traverse moving trolleys.

The robots move using so-called tender carriages. The robots stack the respective side panels to be picked on these carriages. The created stacks are then transferred to the connected exit stack transport system.

A big advantage offered by this system is its low height, this means that the system can also be constructed under platforms or on two levels.

for unit suspension elements and suspenions element rails

This patented robot application places so-called “hidden wall unit suspension elements”, into the pre-pressed carcase that are then assembled behind the back panel. Additionally, the robot then places the suspension element rails into the transport fixation provided.

In the carcase press that follows, the unit suspension elements can be automatically attached at the side at a 45 degree angle. The unit suspension elements – right and left execution – are made available from two bowl feeders, the suspension element rails from a magazine one-by-one.

The robot takes the suspension element and also grabs the suspension element rail. At the same time the carcase arrives at the station and is aligned. When assembling the fittings, it first brings in the suspension elements one after the other, in order to then secure the wall mounting profiles in the transportation fixation of the suspension elements.

Robot processing machines for

In this production system, glass frame fronts are prepared by two robot cells, completed through manual assembly and finished in a final assembly press. A storage buffer is used to provide the pre-fabricated fronts for the entire machine. The fronts have already been drilled by this time. The fittings and hinges such as concealed hinges and soft-closing mechanism have also been set.

In the first cell, the robot processes the front using different tools. It first drills the front in order to then mill the cut out for the glass element. The second robot inserts the mounting profiles for the glass insert fully automatically and secures it with a bracket device.

The plastic strip assembly is followed by manual work stations for the final assembly of the glass-frame fronts. In the final assembly press, the plastic strips are aligned and pressed into their final positions.


This assembly system entails flexible partial and complete solutions for the automated assembly of back and side panels, as well as the drawer fronts. A drawer production of batch size 1 can be created using the automated width and depth adjustment.

The assembly lines have been specially developed for Hettich drawer systems. Besides the assembly units, the machines also contain the magazine loaders and the allocation of the individual parts.

Parallel to the assembly of the drawers, the fronts are drilled and the corresponding fittings and hinges are attached. The drawer is then finally combined with the front.

for inserting glass front sealing strips

This robot continuously inserts sealing strips from a roll into different glass fronts and cuts these sealing strips to size and mitre.

The glass fronts are inserted manually into the front holder and are transported across the work table system into the production cell. The decisive factor in this system is the assembly head for the sealing strip that we developed ourselves.

This assembly head consists of a feed and guide unit, various pneumatically-steered rollers for pressing and a pneumatically operated measuring sensor for handling and processing the sealing strip, as well as a 3D measuring sensor to ascertain the glass cut out.

for reversion flaps

In this production cell, the pre-fabricated aluminium frames are glued onto different sized plaster boards. This entails the manual loading via a transport belt, while the different plaster boards are made available in a holder frame by the pallet.

The automatic recognition of the frame size allows the robot to get the correspondingly sized plaster board from a pallet stack, align the plaster board on an aligner station and guide it along a glue gun.

In the next step the plaster board is laid and secured onto the assembly table, the aluminium frame is taken from the transport belt and placed on top. The frame is then pressed onto the board for a few seconds. Subsequently the finished reversion flap is placed onto the transport belt in order to exit the machine.


In the machine loading area, the robots not only execute work piece handling, but are also used to handle protection plates, trays/mould cavities, pallets or further packaging containers.

In the front-processing machine, the robots handle furniture fronts (image upper right) for example. The robot removes the pre-picked fronts from a front trolley and places these into the machine. The robot then places the processed furniture doors back into the front’s trolley or lays these into the storage buffer for manual reworking.

Robots for loading drawer rails are integrated into the carcase assembly lines for base units. The robots take the drawer rails from the trays in layers and lay these into the buffer magazines. The trays with the drawer rails are stacked on pallets and fed into the robot cell via roller conveyors. The robot calibrates the position of the trays, takes the drawer rails, and handles the empty tray or the empty pallets. 

A further robot application (image bottom right) provides the drawer back panels for the assembly station. Due to the large variety of different types, the robot must access various back panel magazines. That is why the robot travels along the back-panel magazines on a seventh axis that we developed ourselves.
