The design challenge

The machine builder needed to simplify the overall complexity of the machine, optimising space and making the final product more competitive. The initial design was characterised by 12 in-line motor drives to control the same number of independent movements. The machine involved in the project is an automatic injector for filling baked goods, designed for the controlled insertion of creams and fillings into brioches, croissants and other pastry products.

Summary
Before
  • 12 independent motor drives
  • Higher design complexity
  • Higher costs
Objective
  • Single transmission system
  • Selective control of movements
  • Improved machine competitiveness

The solution with GDFN electromagnetic tooth clutches

The adopted solution involves the use of 12 electromagnetic negative-tooth clutches from the GDFN series, mounted on a single transmission shaft driven by one motor only.

Through an electrical control managed via the on-board control panel, it is possible to select and actuate each individual unit, maintaining independent movement control with a simpler and more compact architecture.

In practice
  • Single motor and single transmission shaft
  • 12 GDFN electromagnetic clutches assembled on the shaft
  • Electrical control from the panel: selective engagement of the units

How it works in the application

  • Function Coupling of mechanical components
  • Operating mode Power-off
  • Cycle Frequent engagement/disengagement cycles
  • Operating conditions Intermittent cycles, high torque
  • Key feature No slip
  • Toothing Triangular

Benefits for the machine builder

Component simplification
More streamlined mechanical architecture with fewer elements to manage
Space optimisation
Reduced footprint and improved integration of movements.
Economic benefits
Reduction of the overall machine cost.
Greater competitiveness
More efficient design and stronger market positioning.

Similar applications

This solution is particularly suitable for automatic machines requiring the selective management of multiple movements from a single transmission, especially when simplification, reliability and cost reduction are key factors.

This is a recurring type of application and part of Telcomec’s consolidated experience in developing transmission solutions aimed at component rationalisation and more efficient use of machine space. Projects may start from standard products adapted through limited customisation, as in this case, or from fully bespoke developments, depending on the specific design requirements of the machine.
