Step Feeder & Automatic Stepfeeders

Step Feeders for assembly automation production lines:

Carlson Step Feeders are unmatched in quality, durability, and output capability.

Our step feeders automatically feed screws, nuts, and bolts using a stepfeeding elevator step mechanism. A built-in 3-step fastener alignment verification method ensures that stepfeeders are only feeding or presenting screws that are oriented properly, effectively eliminating track-level fastener jamming/blockage.

How do step feeders work?

Stepfeeders work by lifting fasteners up from a tray, which holds hundreds of fastener, into an escapement track with a screw elevator.

The step feeder’s motorized screw elevator lift assembly automates the process of loading screws into the track, whick makes our unique stepfeeders an incredibly effective means of feeding screws to an automatic screwdriver drive head.

This process of feeding results in a streamlined manufacturing workflow that is unparalleled by traditional screw feeding methods – and, because stepfeeders do not rely on vibratory motion (like traditional vibratory bowl feeders), step feeding is a better solution for feeding screws which are coated with substrates such as Loctite.

This is because the step feeding process is low-abrasion, and the screws don’t become overly scratched. This also preserves the lifespan of the step feeder itself, as the tray and escapement track will be in better condition for a longer period of time than a vibratory bowl feeder.

Carlson Engineering sells step feeders at three main sizes:

All of our stepfeeders are available with an optional fastener hopper, which comes in three different corresponding sizes and varying capacities to accommodate for the different-sized screws which will be fed. Additionally, and stepfeeder (whether with or without a hopper) can be fitted with a plexiglass enclosure with aluminum framing, which serves to keep contaminants such as dust particles out.

The enclosure also aids in reducing the noise output from the step feeder, which results in an ultimately more silent screw feeding option.

Enhancing the effectiveness of assembly automation processes...

Stepfeeders & Step Feeder Presenters use a pressurized stream of air when feeding screws to automatic screwdrivers or screw dispensers.

The screw elevator lift assembly, which is used in place of the conventional vibratory bowl, helps to reduce noise, and also provides less agitative handling of coated screws.

When combined with the high-capacity output of an automatic hopper feeder, Carlson step feeders can run for hours unsupervised with very minimal maintenance!

The elevator lift assembly lifts screws out of the tray and into the escapement track, resulting in the elimination of uneven coating distribution among fasteners coated with substrates such as loctite.

Step feeder anatomy...

Anatomy & features of the step feeder & stepfeeder presenter.

  • Resistant to wear & tear damage
  • Non-magnetic nickel-teflon coating
  • Ideal method for silently feeding/presenting coated fasteners
  • Hardened & heat-treated durable tool steel composition
  • Longer run time between feeds due to less track level fastener jams

Common features & advantages of step feeders:

  • A screw elevator in place of a bowl is quieter, and agitates the screwss less than a vibratory bowl feeder device
  • 3-Step fastener alignment verifications ensures that jams along the track and escapement are not possible with our systems
  • Hardened, heat treated build is highly resistant to wear & tear damage
  • Combine with a non-magnetic stainless steel, nickel-teflon coated gravity track or a heat treated tool steel inline track for maximum durability
  • Abilty to feed or present extremely large and extremely small screws, depending on the device being used to feed the screws
  • No mechanical adjustmens to the entire device means greater accuracy and safety
