How It Works

Core Principles

The ZiPsort Shoe Sorter operates on an all-electric divert mechanism, utilizing precision servo motors to control the timing and movement of the sorting shoes. Unlike pneumatic systems that can have inconsistent performance, the electric servo-driven design ensures accurate, repeatable diversion of products. The system uses dedicated local PLCs with integrated pin sensors to precisely time the release of shoes, guaranteeing that each package is diverted to the correct chute every time. The sorter can be configured with divert centers at either 30° angles for sortation rates up to 350 feet per minute or 22° angles to achieve maximum throughput speeds up to 650 feet per minute. A key principle of its design is crash avoidance, enabled by the no pinch profile shoes and deflected bumpers that minimize product and equipment damage.

Key Features & Capabilities

The all-electric design of the ZiPsort Shoe Sorter is one of its most impactful features, replacing traditional pneumatic divert mechanisms with precision servo motors. This electric configuration eliminates the inconsistencies and maintenance issues associated with compressed air systems, delivering reliable, repeatable divert performance. The integration of dedicated local PLCs with integrated pin sensors further enhances precision, ensuring that each package is diverted accurately every time. This level of control is critical for high-throughput operations where mis-sorts can lead to significant delays and increased costs.

Another standout capability is the system's exceptional throughput and speed, reaching up to 18,000 cases per hour and 650 feet per minute when configured with 22° divert angles. For operations that balance speed with specific sortation requirements, the 30° angle configuration still delivers an impressive 350 feet per minute while maintaining high accuracy. This flexibility allows facilities to tailor the sorter to their exact operational needs, whether prioritizing maximum volume or optimized space utilization.

The no pinch profile shoes with deflected bumpers represent a key innovation in product and equipment protection. Unlike standard sorter shoes that can pinch or damage products during jams, this specialized design ensures that products are elevated over the shoes in rare jam events, preventing both product damage and slat displacement. The deflected bumpers absorb impact, reducing wear on the sorter itself and extending the equipment's service life. This feature is particularly valuable for operations handling fragile goods or high-value products.

Ease of maintenance is a core capability of the ZiPsort Shoe Sorter, enabled by quick release slats, drop out switches, and an open frame design. Maintenance personnel can replace slats and shoes with minimal tools, significantly reducing downtime compared to sorters with complex, bolted components. The removable side covers provide easy access to the quick change switch assembly, simplifying inspections and repairs. Additionally, the UHMW slat surface is smooth and non-porous, making it easy to clean— a critical feature for food and beverage operations that must adhere to strict hygiene standards.

Finally, the sorter's quiet operation is a notable capability that enhances workplace comfort. The all-electric design and noise-isolating components reduce operational noise compared to pneumatic sorters, creating a more comfortable environment for nearby associates. This feature addresses a common pain point in high-throughput facilities, where loud equipment can lead to worker fatigue and safety concerns.

Advantages & Benefits

The high throughput and speed of the ZiPsort Shoe Sorter directly translate to significant productivity gains for high-volume operations. With the ability to process up to 18,000 cases per hour, facilities can handle peak demand periods more effectively, reducing order cycle times and improving customer satisfaction. For e-commerce fulfillment centers and retail distributors, this means faster order processing and shipping, which is a key competitive advantage in today's fast-paced market. The flexibility to choose between 22° and 30° divert angles further allows businesses to optimize the sorter for their specific throughput and layout requirements, maximizing the return on investment.

Minimal downtime is a major benefit of the ZiPsort Shoe Sorter's design, driven by its quick-change components and reliable all-electric system. The quick release slats and drop out switches enable maintenance teams to perform repairs and replacements in a fraction of the time required for conventional sorters, minimizing production interruptions. The precision chain and lubrication system also reduce wear and tear, lowering the frequency of maintenance interventions. For facilities that operate 24/7, this reduced downtime can translate to thousands of additional cases processed annually, directly impacting the bottom line.

Gentle product handling is another key advantage that delivers tangible cost savings. The no pinch profile shoes and deflected bumpers minimize product damage during sortation, which is particularly valuable for food and beverage products, fragile goods, and high-value items. Reduced product damage lowers waste and replacement costs, while also improving the quality of outgoing shipments.

Implementation Considerations

Proper angle configuration is a critical consideration when implementing the ZiPsort Shoe Sorter. The system's maximum throughput of 650 feet per minute is only achievable with divert centers configured at 22° angles, while 30° angles deliver a still-impressive 350 feet per minute. Facilities must carefully assess their throughput needs, available space, and product characteristics to select the optimal angle configuration. Incorrect configuration can lead to suboptimal performance, so close collaboration with the system integrator is essential during the design phase.

The precision servo motors and local PLCs that power the ZiPsort Shoe Sorter require specialized maintenance knowledge. Unlike conventional sorters that may use more common components, these advanced electric components need technicians with expertise in servo systems and PLC programming. Facilities should plan for training their maintenance teams or partnering with a service provider that has experience with the ZiPsort system to ensure that repairs and maintenance are performed correctly. This specialized knowledge requirement can be a barrier for some operations, so it should be factored into the implementation planning process.

Safety guarding is an important consideration given the sorter's open frame design.
