T5 Low Headroom Unloader

For unloading in areas with restricted headroom

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.

HOW IT WORKS

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:

  1. A bulk bag of product is fitted with the Bag Lifting Frame.
  2. The operator will lift the bulk bag into place with a forklift into the separate upper frame assembly.
  3. The Lifting Frame rests on the Side Tensioning Frame.
  4. The weight of the bag compresses the springs & the bottom of the bulk bag rests on the Support Dish.
  5. The operator will use the forklift to lift the entire upper framework from below the bulk bag & position it into the base frame.
  6. With the weight of the bag safely supported, the operator can now freely access the bottom spout of the bag.
  7. The operator opens the access door & unties the bag spout.
  8. 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.

MODELS & SPECIFICATIONS

The T5 bulk bag unloader is one of several designs we offer.  Features of our various models are typically mixed and matched to accommodate specific application needs.  And, of course, we regularly build custom designs.  Here is a list of our basic models.  Your Spiroflow Sales Engineer will evaluate your needs and recommend the best configuration to do the job.

MODELDESCRIPTION
T1Entry level basic frame design available in the UK & Europe
T2For unloading by volume
T3For loss-in-weight unloading
T4For unloading single trip bags
T5For discharging in low headroom areas
T6Includes an integral hoist when a forklift truck is not available to load/unload bags into/out of the bulk bag unloader
T7For unloading multiple types of containers including bulk bags, rigid bins & boxes/octabins
T8For USDA/3A applications
T9-CVFor total containment when handling volatile or explosive materials
T10 & T11For pharmaceutical applications
Flo StyleFlo Style unloaders, from our purchase of Control & Metering, have a 40º or 60º sloped hopper that supports & shapes the bag for ease of discharge. Pulse vibration, instead of massage paddles, is used to induce material flow. The bag is kept elongated via gravity throughout discharge. It can be configured as a T2, T3, T4 or T6.

YOUR UNLOADING REQUIREMENTS

Before purchasing a bulk bag unloader always ask these key questions:

  • Will the bulk bag unloader accept varying bag sizes?
  • Will the bulk bag unloader handle poor flowing products?
  • Is there a forklift available or is an integral hoist needed?
  • Does the bulk bag unloader provide a controlled flow when the spout is opened?
  • Does the bulk bag unloader have a bag tensioning device to ensure all product is discharged?
  • Is discharge of the bag contents required by weight or by volume?
  • Is there provision for restraining and/or removing the inner liner?
  • Is an integral take-off conveyor required?
  • Is there a height restriction?
  • Is there a way to empty small bags in case the bulk bag supply of material is interrupted?
  • Does your plant require a hygienic bulk bag unloader or USDA/FDA approved equipment?
  • What dust control features are incorporated into the bulk bag unloader?
  • When untying the bag spout
  • While the product is being discharged
  • When the inner liner is being removed
  • When the bag is removed and folded for disposal
  • Is the product or environment hazardous?
  • Is static grounding and monitoring required?
  • Is the environment covered by NEC regulations?
