1. Unloader
Brings hand-loaded packages, introduced to the unloader by a package handler, into the sortation process.
ISSUES
Belt tracking issues are damaging the belt due to unsquared belt splices, belt over tensioning, or incorrectly installed hooks.
SOLUTIONS
SmartClamp™ Belt Clamps work particularly well when stringing new belting onto an extendable loader. The SmartClamp engages quickly with the belt, while the pull loop provides a handle for hand pulling the belt onto the extendable unloader.
Belt splices that are not installed into a square cut belt end are a primary cause of belt tracking issues with unloaders. The Laser Belt Square is the quickest and most accurate way to locate your perfectly-square belt cutting reference line.
The 845LD Belt Cutter is widely accepted as the wide belt cutter of choice. It allows for the safe cutting of the belt in a single pass and a quick engaging belt clamp system, easily toggling over to apply the perfect amount of spring-loaded pressure to the belt, preventing belt migration during the cut. This ensures a straight cut every time.
Quick to install with great performance, Clipper® and Anker® Wire Hooks are the belt joining method of choice. The most common sizes of wire hooks used with unloader conveyors are #1 and #2SP carded style, in High Tensile (HT) wire. Unibar UX1 (A40) and U2SP (A2SPS) in 430SS are also used. The HT carded is the best choice for added impact resistance and extended wear life.
The Nylosteel Durastainless™ (DSS) Hinge Pin is perfect for use with unloader conveyors. In extendable unloaders there are a minimum of 10 pulleys that the belt makes a transition around. The increased hinging action requires a better-wearing pin like the DSS.
Roller Lacer® and Roller Lacer® Gold Class™ installation tools are perfect for quickly installing wire hooks in one single, easy operation, ensuring that the splices are installed correctly.
1 a.) SMALL SORT PROCESS – Secondary Sort
A sortation dedicated to small packages. The small sort is fed both from the primary sort, through the use of shipping bags, and from the inbound tractor trailers. Packages coming from the tractor trailers are placed on a Small Sort Transport Belt that only feeds the small sort. The shipping bags that are filled with packages are arriving from other hubs can also be placed on this belt, but are often placed into the general primary sort where they are diverted to the small sort area of the plant along the way. Smaller sortation hubs also use a manual process to sort the small packages and parcels.
ISSUES
- Small packages or envelopes are becoming lodged in the transfers.
- Belt splice failures are occurring due to worn hooks and hinge pins.
- Improperly squared belts are causing belt tracking issues that could damage the belts.
SOLUTIONS
Flexco Segmented Transfer Plates are designed to be placed with little to no clearance between the segments and the belt. This helps to greatly reduce the chances of envelopes, plastic shipping bags, and other small parcels getting sucked into the transfer and damaged.
Clipper® and Anker® High Tensile Wire Hooks are easy to install and a great option to increase splice life, providing superior abrasion resistance.
Durastainless™ (DSS) Hinge Pins provide up to 10 times the wear life. This keeps the small sortation lines up and running during critical sortation times.
The Laser Belt Square will make finding an accurately-located square cutting reference line much easier. Using the Laser Belt Square will significantly reduce belt tracking issues related to crooked splices caused by unsquared belt ends.
- TILT TRAY SORTER – Secondary Sort
Part of the secondary sort, this conveyor runs in a continual oval pattern with a tray on top of each “car.” When the tray reaches the proper location it will tilt or tip, allowing the small package to slide off.
- CROSS BELT SORTERS - Secondary
Part of the secondary sort, these articulating belt conveyors divert packages off to their destination chute.
ISSUES
The endless splices are failing, resulting in belt damage.
SOLUTIONS
The Novitool® Aero® Splice Press and the Novitool® Pun M™ Mobile Finger Punch provide the fastest and most accurate endless splicing available. And the flexibility of power options through the simple change of a cord allow the Aero Splice Press to be used virtually anywhere in the sortation facility.
