Reliable automatic product rejection for quality control and inspection lines

Reject Systems

Product Overview

Engineered for Your Production Needs

Saturn Reject Systems provide automatic removal of non-conforming products from production and packaging lines. Reject systems can be integrated directly into virtually any conveyor type and customized according to the product, line speed, reject frequency and available space. Reject mechanisms can include pneumatic pushers, servo pushers, finger pushers, air blow systems, drop-down conveyors, retracting conveyors, diverters, gates and lift-up reject systems. The reject mechanism can be pneumatically or servo driven depending on the required speed, precision and product characteristics. Pneumatic systems provide a simple and reliable solution for many standard applications, while servo-controlled systems provide precise motion control for high-speed or high-frequency rejection. Reject systems can receive signals from upstream inspection equipment including metal detectors, X-ray systems, checkweighers, vision systems, barcode readers and other quality-control devices. Once a rejected product is identified, the control system tracks the product and activates the appropriate reject mechanism at the correct position. Rejected products can be directed into lockable reject bins, collection containers, chutes or separate reject conveyors. Systems can also incorporate reject confirmation sensors, bin-full detection and other controls when required. Saturn Reject Systems can be integrated with belt, modular belt, tabletop, MatTop, metal mesh and powered roller conveyors, allowing the reject solution to be engineered around the existing production line rather than requiring a dedicated conveyor technology.

Drive Options

Pneumatic Rejects are ideal for straightforward, repetitive reject motions and provide a cost-effective solution for many production lines. Servo-Driven Rejects provide greater control over acceleration, position and timing, making them suitable for high-speed lines, delicate products and applications requiring precise reject motion.

The COMBO models offer a compact L-bar sealer and shrink tunnel in one frame with high reliability which makes it a very popular product

Simple and easy to use machine with a user friendly interface to cover a vast range of packaged products: cosmetic, pharmaceutical, food, beverage, industrial product. Single or multipack products are manually loaded on the working table. The ergonomic sealing arm covers the heating element which creates the perfect seal. The motorized conveyor eases the product transfer into the heat chamber for the ultimate package.The integrated heat tunnel features a top, bottom and side heated air flow, twin blowers, teflon mesh belt that are all controlled with the SATU digital keypad
