Step screw feeders
SOLUTION FOR COMPLEX PARTS
For parts that are not geometrically suitable for a bowl-feeders, a step feeder is often the solution. It can feed screws or other parts with a centre of gravity inside the head, long screws, or other special parts.
QUIET AND GENTLE FEEDING
The step feeder has a very quiet operation due to the minimal oscillating mass. The parts are lifted from magazine on the bar, thus minimizing their mutual abrasion and possible damage from being in the feeder.
Principle of function
The parts are fed from the hopper into a bowl from which they are gradually transfered to a vibrating bar. The vibratory bar orients the screws and then each screw is separated and fed into the transport hose.
The system is largely configurable and customer can select from a wide range of accessories and options. Contact us for a quote tailored to your exact needs.

Cleaning and measuring of the screw
In the cleaning module, the screw is cleared of dust and debris just before being fed into the screwdriving head. As this is a parallel process, cleaning does not extend the feeding time and can be used in applications with cycle times of under three seconds.
JHV screw measurement modules most commonly measure the screw length. This control prevents the possibility of mixing in a different types of screw and its use in the product. In addition to length, it is also possible to measure the head diameter, bit quality, presence of threads, and other screw parameters.
Camera orientation unit
In applications where it is not possible to orient the screw mechanically, we use the camera orientation unit. The actual orientation of the screw is detected by a camera just in front of the separator. Separator is than equiped with rotation unit that orients the screw in the desired direction.
Additionaly to orientation camera cen evaluate quality features of screw.
Pneumatic terminal (FESTO / SMC)
If needed, the feeder can be equipped with Festo or SMC pneumatic terminal. The specific type and variant of network communication can also be defined.
Input and output modules
In addition to the pneumatic terminal, the feeder can also be equiped with DI/DO modules. If a pneumatic terminal is also used, the connection of the feeder to the line consists only of the power supply, communication and compressed air.
ESD design of the feeder
The feeders can be built in the ESD version. In such case are ESD certified materials used in the necessary places. The feeders can then also be used for components susceptible to damage by electrostatic discharge.
Device frame
If the feeder is not integrated into the line, but is a stand-alone device, JHV supplies it on a aluminium frame with wheels to facilitate possible handling. The height of the frame can be defined by the customer.
Hopper - capacity according to your requirements
You can choose from the smallest 3 litre impact hopper, through 5, 10, 15, 20 litres pneumaticaly driven belt hopper up to big multilevel hopper with capacity 100 litres or more.
The belt drive can be pneumatic or electric and we can always help you choose the right hopper size.
The hopper can be equipped with a cover lock and in combination with a bar code reader prevent unintentional screw batches mixing.
