Longitudinal transport: Platform with linear motion system for filling and assembly (intermittent)


The FLT platform provides the capability to integrate many stations in the assembly machine, and to thus be able to process a large number of components. With the linear, lean setup, the material flow is clearly arranged, the feeding technology is ideally positioned and isolating technology can be used.

  • Simple integration of technologies allowing the dosing of medications for inhalers or the filling of liquid ingredients and pellets for diagnostic products.
  • Optimum accessibility
  • High availability high cycle rates
  • Efficiently stops active ingredient substances from spilling
  • Video

    System for filling, assembly and labeling powder inhalers based on the FLT longitudinal transport machine platform.

  • FLT diagram

    The products are transported to each of the processing stations on product mounts via longitudinal transport in the FLT machine platform.

  • Assembly and filling in the FLT DPI machine

    On the basis of the FLT platform, powder inhalers are filled, each product component is assembled and is then labeled. Integrated weighing process and camera inspections guarantee perfect processing.

  • Pre-assembled DPI inhalers are inserted in the longitudinal transport

    Product handling: Pre-assembled DPI inhalers are set onto the transport conveyor.

  • Assembling inhaler components within the FLT

    Product handling: DPI inhaler components are assembled within the FLT.

  • Capping the inhalers within the FLT

    Final assembly: The filled powder inhalers are closed with caps.

Machine features

Parts handling

Components are automatically taken out using vacs, grippers or tongs and accurately transferred. This can be performed in a linear or swivel movement. To increase the output, these systems can be set up at multiple locations so as to perform loading and unloading tasks at the same time.


Automated logistics concepts control how product components are fed via feeding unit and regulate the transport systems within the machine. Robot and automation technology is intended to insert components into production machines and to handle them during assembly.

Final assembly

Joining technology is one of the basic processes for completing assembly groups. Highly precise processes and gentle handling are perquisites to ensuring that components are reliably joined. Inspection and measuring systems guarantee the highest possible quality, even at high speeds.

Barrier technology

Compact machine design and detailed knowledge of all processes makes Harro Höfliger a specialist in containment and barrier systems that serve to protect both the operator and the product. For ideal accessibility, ergonomic studies are performed that simulate all processes and operating steps.
