All modules at a glance

The wide range of modules in the Sigma transfer system guarantees maximum flexibility in the event of changes to premises, production figures or production processes. Long set-up and changeover times associated with high costs and the associated forced breaks are avoided. The transfer system can be supplied either fully assembled or modularly pre-assembled and ready for self-assembly at the customer's request.

Drive modules

90° / 180° drives drive the standard chain continuously (up to 60 m in length). One drive is required per cycle.

Linear modules

For connecting and guiding the chain between different modules.

Chain tensioners

Ensure the necessary chain tension. Used from a chain length of approx. 20 m or more or from a total of more than 720° direction changes. Pneumatically adjusted.

Idler fixed

45° / 90° / 180° fixed deflections to change direction.

Idler rolling

45° / 90° / 180° rolling deflections to change direction. Reduced resistance between transport chain and deflection by rollers.

Idler rotary

90° / 180° rotating deflections to change direction. Significantly reduced resistance between transport chain and deflection due to rotating deflection wheels.

Intersection modules 1

Enable the workpiece carrier to be diverted to a parallel secondary section in the smallest of spaces and with minimum control effort.

Intersection modules 2

Enable the connection between a main and secondary circuit in the smallest of spaces and with minmium control effort.

Intersection modules 3

Enable two circuits to be connected. The drives of the standard chain per circuit are already integrated in the module and therefore the drive modules are not required for both circuits.

Intersection modules 4

Enable the connection between a main and secondary circuit with simultaneous running in and out of the secondary circuit through the two short belt sections.

Intersection modules 5

Enable the connection between two circuits with a buffer section that is variable in length.

Cross modules

Guide workpiece carriers from one circuit to another. For example, to bypass cells, workstations or manual workstations.

Turntable modules

For connecting two circuits with opposite running direction.

Linear conveyor modules

Autonomous secondary lines with their own drive. These are connected to the circuit via cross travel modules.

Cross transfer modules

Guide workpiece carriers to a second parallel circuit or a parallel belt.

Circuit transfer modules

Connect two circuits without any control effort and small space requirement, thus two circuits can also be connected with different chain speeds.

Soft motion conveyor

Enable a freely programmable speed, gentle vibration-free stopping and acceleration of the workpiece carriers, reduction of cycle times, reversibility.

Support modules

Serve to support the longitudinal section modules, available in all system widths. Also available as an expandable version for two sections, as shown.

Offset modules

Extend the possibilities and flexibility in layout and concept design even further. Can be adapted to project and customer specifications.

Chain deflection modules

Enable access or machining of workpieces from below.

External part remover

Serves to remove foreign bodies, dirt and dust on, next to and below the transfer chain. Available in two versions or according to customer requirements.

Manual workstations

Serve as an assembly surface or as a storage compartment for tools and assembly materials. Ergonomic, smart and easily integrated into the transfer system.

Chain tensioner linear

Ensure the necessary chain tension, does not require 2x90° or 180° deflection as the chain tension is ensured lengthwise. Pneumatically adjusted.

Pallets

Workpiece carriers transport the workpiece on the transfer system.

Indexing modules

Centring and positioning of stopped workpiece carriers in a defined position. (+/- 0.06 mm)

Indexing modules
elevated

Centring and positioning of stopped workpiece carriers in an elevated defined position. (+/- 0.06 mm)

Indexing modules
precision

Centring and positioning of stopped workpiece carriers in a defined, precise position. (+/- 0.02 mm)

Stop modules

Used for controlled stopping (fixed) and release of workpiece carriers.

Stop modules
damped

Used for controlled stopping (damped) and release of workpiece carriers.

Overtaking modules

Enable centring and positioning of the stopped workpiece carriers (+/- 0.04 mm), while other workpiece carriers can continue to travel simultaneously. This advantage saves outfeeds.

Special modules

Idler modules angle
as needed

30° / 45° deflection manufactured according to customer requirements and application. As fixed or rolling variant.

Pull- / Push modules

Enable access or machining of the workpieces from below without influencing the further flow of the workpiece carrier. Also suitable for longer process times.

Chain tensioner mechanical

Ensure the necessary chain tension is used from a chain length of approx. 20 m or more or from a total of more than 720° directional changes. Mechanically adjusted.
