T5 Low Headroom Unloader

System OVerview

Spiroflow’s T5 low headroom bulk bag unloader empties bulk bags and bags in process areas where restricted headroom causes problems in handling bags or where only a low lift forklift is available.

This model is coupled directly to a flexible spiral or another suitable conveyor which meters ingredients from the bag either volumetrically or by weight. Ingredients can then be fed directly to mixing or other process equipment to provide a fully automatic ingredient unloading, proportioning and transfer system. The height of the access door has been designed to receive small bags, which is particularly beneficial to processors who have switched over to bulk bags but still continue to receive minor ingredients in 50 lb bags. Processors with batching operations may choose to have several bag frames for use with one discharge station, allowing them to partially empty, re-tie and store bulk bags.

Features

HOW IT WORKS & BENEFITS

The T5 Low Headroom Bulk Bag Unloader is used in areas with restricted headroom.

The bulk bag is loaded onto the Bag Support Dish Assembly while the dish is at ground level & then lifted onto the support frame with a forklift.

This design is used where there is limited overhead clearance.

The support frame is designed with large channels designed to receive the Support Dish Assembly.

It includes a dust seal between the upper & lower sections.

The discharge of the chute is custom made to fit the application.

The process steps are as follows:

A bulk bag of product is fitted with the Bag Lifting Frame.
The operator will lift the bulk bag into place with a forklift into the separate upper frame assembly.
The Lifting Frame rests on the Side Tensioning Frame.
The weight of the bag compresses the springs & the bottom of the bulk bag rests on the Support Dish.
The operator will use the forklift to lift the entire upper framework from below the bulk bag & position it into the base frame.
With the weight of the bag safely supported, the operator can now freely access the bottom spout of the bag.
The operator opens the access door & unties the bag spout.
As the bag empties, the springs in the side frame will keep a constant tension on the bag ensuring complete emptying of its contents.

STEP 1: Lift Off Top Section

STEP 2: Position Bulk Bag & Attach Lifting Frame

STEP 3: Move the Top Frame into the Unloader

STEP 4: Move the Top Frame into Position

The bulk bag is ready to empty.
