Flexible Manufacturing Areas require handling heavy parts during the assembly of products according to ergo requirements.  In the market we can find traditional devices that allow handling without effort with a certain lack of control. And if control is demonstrated, it probably reduces the capability of the operator for doing different operations simultaneously, affecting the productivity of the overall process.

A new device has been developed that allows the overlapping of handling load with the assembly of parts.  Many times it is not only a productivity aim, but a need of space and comfort for the operator during the process with high volumes of production.

In the traditional approach [Fig. 1] shown below, the balancer compensates the load applied according to the air supply signal that the operator applies while pushing the up/down buttons.

The balancer has as input an air supply signal that will apply a constant force to compensate the weight of the load.

The new approach [Fig.2] is based on a pneumatic device with a high level of control.

As you can see in the diagram above, APM  [ Fig.2 ] is a device that transforms the weight of a load in a piloted pressure signal Pp.  Pp is used to control the pressure regulator PPR which itself modifies the output pressure. The final output signal P can so be applied to a generic mechanical actuator  (typically a pneumatic balancer) that allows raising the load without e...
