Vibratory Bowl Screw Feeder Systems
Single & multi spindle automatic screwdrivers completely automate the screw driving process along an manufacturing assembly line when mounted to third party robotic arms and positioning systems.
Custom-engineered for your production process.
Vibratory bowl feeders designed for automated fastening manufacturing applications...
Carlson automatic screw feeder bowls automate the screw driving and assembly process by providing a steady stream of screws to the screw driving unit using a pressurized stream of air flow, enabling extremely short cycle times and automated, hands-off automatic run times.
When combined with an automatic hopper feeder, our screw feeder systems can potentially run for hours unsupervised with confidence and precision. For applications in medical device manufacturing industries, or other industries requiring cleanroom environments for assembly automation, we also offer a sound and dust-proofing enclosure for our blow feed automatic screw feeder machines.
What makes our screw feeder devices so unique is the level of attention to detail that goes into the prevention of fastener jams. Jams along the track and in the screw escapement are one of the leading causes of frustration for automation engineers and assembly line builders when implementing screw feeders or presenters, so we have managed to build a fool-proof series of mechanisms, which we call the 3-step fastener alignment verification process, directly into the track. It is virtually impossible for a screw to become jammed along the track of a Carlson feeder, as there are too many precautions in place to allow for this to occur!

It is virtually impossible for a screw to become jammed along the track of a Carlson feeder, as there are too many precautions in place to allow for this to occur.
Step 1: Sorting Air Jet
The first step in our 3-step fastener verification is our Non-Adjustable Sorting Air jet – a highly pressurized stream of air that ejects misaligned fasteners from the track - our first line of defense.
Step 2: Qualifying Track Cover:
The second step is a Non-Adjustable Bowl Track Qualifying Cover, which prevents misaligned fasteners from passing underneath its clearance and moving down the escapement track in the first place.
Step 3: Optic Sensor
When the optic sensor notices that the escapement is full, the bowl will cease vibrations, stopping the flow of fasteners to the escapement. This prevents back pressure in the bowl, stopping jams before they occur.
Carlson screw feeder advantages:
Carlson screw feeder systems carry with them the following advantages over other manufacturers’ models:
- Heat Treated: Hardened, heat treated build is highly resistant to wear & tear damage
- Bowl Coating: Bowl is standard polyethylene coated, but can be configured with hard anodization or urethane
- Error-Proofing: 3-Step fastener alignment verification ensures that jams along the track and escapement are not possible with our systems
- Minimal Adjustments: No mechanical adjustments to the entire device means greater accuracy and safety
- Non-Magnetic Track: Non-magnetic nickel-teflon coating aids in preventing troublesome screw jams.
- Adaptability: Ability to feed or present extremely large and extremely small screws, depending on the device being used to feed the screws.
