High rigidity – low moving mass
Optimised cantilever axis in compact design for shorter cycle times and less vibration. Ideal for use as a vertical Z-axis, e.g. for palletising or erecting boxes. Used horizontally or at any other installation angle if the axis has to be removed from the work area.
- High rigidity for up to 50% less vibration
- Compact design and lower moving mass for shortening cycle times by up to 30%
- Stainless steel cover strip to protect the internal recirculating ball bearing guide
- Sealing air for use in a dusty environment or on machine tools
- Clamping unit for a secure hold of the load and as an emergency brake – double stop with additional slide
Typical applications of a cantilever axis with toothed belt
Box erector (secondary packaging)
As the first module in a packaging system, the box erector ensures that the box is folded correctly and precisely as well as quickly and economically. The ELCC takes on the vertical linear function at the erecting station.
Its technical performance data enables almost all box materials and thicknesses as well as box sizes to be folded using the ELCC series. The compact and rigid design enables short cycle times and long strokes.
Box lidder (secondary packaging)
The last module in the packaging system before the palletiser folds the packaging lid and places it on the assembled box. This last step ensures that the packaged goods are packaged and well protected in the box.
The ELCC takes on the vertical linear function for folding and placing the lid. Here too, the rigid design and dynamic performance data of the ELCC come into their own and make for short cycle times and an optimised, low-vibration machine layout.
Palletiser (tertiary packaging)
The palletiser is usually located right at the end of a packaging line. Pre-assembled boxes or other packaging units – the so-called secondary packaging – are stacked on a pallet at this station.
This last step in the packaging system places the highest demands on cantilever axes such as the ELCC – high payload and long stroke, short cycle times and optimum vibration behaviour. Here too, the impressive design and performance data of the ELCC enable dynamic loading of the pallet – precisely and efficiently, without post-pulse oscillations and vibrations.
Key features of the ELCC series at a glance
Design follows function
The axis layout with motor at the Ω drive head as well as the separation of the toothed belt drive and guide with 90° offset enables a design that is both slim and light, but also rigid. This reduces the moving mass and at the same time greatly increases the permissible load capacity of the axis and significantly reduces vibrations.
- Side effect: the ability to use a smaller size with the same load or higher loads with comparable sizes than was previously the case
- Plus point: its mechanical design enables the ELCC to deliver higher speeds and accelerations with the same payload – and thus shorter cycle times
Variety, flexibility and safety
- ELCC in 4 sizes with up to 2 m stroke and max. 100 kg payload (vertical)
- Flexible motor mounting upwards or downwards, axially or with angular gear unit – freely convertible at any time
- Different toothed belt materials: standard toothed belts for long service life; polyurethane toothed belts for the food industry, FDA-compliant; coated polyurethane belts for special applications, e.g. in machine tools
- Protection of the recirculating ball bearing guide through stainless steel cover strip and additionally by sealing air – ideal in dusty environments and on machine tools
- Clamping unit inside the cantilever axis for holding the load without energy or for emergency braking – in the event of power failure or line break, the stationary axis is clamped
- Optional additional slide for increased guidance requirements, to reduce vibrations, e.g. during long strokes, or including clamping unit for two ways of holding the axis
- Incremental displacement encoder for position detection and inductive proximity sensors for homing or for end-position sensing
- Mounting a shock absorber for cushioning the end-position impact in an emergency, e.g. during setup.
