To prevent tampering, we’ve engineered our automatic step feeder systems so that there are no mechanical adjustments. All parts of our step feeder mechanism are machined to the specifications of your particular fastener, and dowel pinned in place. This make maintenance of our stepper feeder systems easy: the escapement can be taken apart for cleaning, and it will go back together precisely as originally manufactured.
Our track level sensor is custom made for the Carlson escapement, ensuring superior accuracy & fastener compatibility. This sensor mounts to the escapement track and requires no positional adjustment, like the rest of our tooling. The sensor’s sensitivity is preset from the factory, and in most cases does not require adjustment.
One of the most frustrating challenges caused by modern vibratory feeder bowls is the frequency of fastener jams. To solve this, we have engineered a unique 3-step fastener alignment verification process into our automatic screw feeder machines.
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.
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.
When the optic sensor notices that the escapement is full of screws, the step feeder's screw elevator will stop lifting fasteners to the track. This prevents back pressure and jams in the feeder tray.
Every assembly is different. That’s why we’ve engineered adaptability into our single-spindle drive heads – so that no matter the application, we have a drive head that will work for you. Each type of drive head has different qualities which make it more suited for a particular style of fastener driving.
Type 1 drive heads include a dual-stage travel slide, with two travel strokes.
Primarily used for pick & place presenter applications or nut-running with a vacuum finder.
Type 3 drive heads are intended for driving pre-placed screws, nut running, and bottle-capping.
Type 4 drive heads have a single-stage travel slide – opposite of the Type 1 drive heads.
A drive head that is configured with a vacuum bit extend option, designed to work with a blow feeder.
A drive head that is configured with a magnetic bit extend option, designed to work with a blow feeder.
