AS40 Backlight Conveyor


Integrated Backlight

Backlights are used in a wide variety of machine vision applications to provide contrast for part inspection or robot orientation. The contrast from the backlight allows for better resolution from the vision system than reflective lighting can provide.

Flush Fit Backlight

The backlight mounts to the cross member of our AS40 frame, where it fits flush with the top of the frame, eliminating sharp edges that could cause premature wear of the belt.

Single Piece Aluminum Frame

Box Frame Construction for Rigidity

The frame is the backbone of the conveyor. A sturdy frame helps to ensure positive tracking throughout the life of the conveyor. That’s why we designed ours with a box-frame construction that resists both latitudinal and longitudinal deflections. Conveyors 18” and wider feature a rigid aluminum/steel frame.

Crowned Pulley

Ensures Accurate Tracking in Most Applications

On any conveyor, the belt pulls to the longest point on the conveyor. By using a crowned pulley — that’s higher in the center than at the ends — we’re able to ensure proper tracking in most applications without the use of a v-guide. The straight knurling provides positive traction, but allows the belt to float slightly from side to side without damage.

Tension Release Tail

Flips up at the push of a button

Tension Release Tails flip up at the push of a button to relieve tension on the belt. This makes it easy to clean under the belt. A gentle push locks the tail back into place with tension and tracking setting retained.

V-Guide Belt Capable

Proper tracking for demanding applications

All Automation Series conveyors support optional v-guide belting, which works to keep the belt centered in applications with side loading/exiting or reversing.

Optional Nosebar Tail

Ideal for Transferring Small Products

Optional nosebar tails allow for transfers of small products between conveyors. The tighter 11mm radius of the pulley reduces the gap between pulleys.

Powered by Spectrum Illumination

We’ve partnered with Spectrum Illumination, leaders in the machine vision lighting industry. They’ve designed a special backlight meant specifically for the low-profile form factor of our conveyors. It features a white housing that disperses light nearly to the edge of the conveyor.

Once the project launched, the conveyor system took off with minimal adjustments;
this says a lot for the design and quality of the QC Conveyors product.
