The Jumbo Bag filling machine is positioned under the main storage Silo. There are 2 types of Jumbo Bag filling machines. Some Customers prefer weighing of the Jumbo Bag on a platform placed at floor level while some prefer weighing on a frame hanging at the top.

1) First Model:A weighing frame is provided at the floor level for placing the empty bag. The weighing frame rests on high accuracy load sensors. There is a frame at the top with 4 bag hooks provided on a structure. The bag is hung on this holder and the mouth of the bag is then clamped to the filling head. The filling head is designed to accept the material discharged from the storage hopper through a dual flap gate. The material is fed in two modes, i.e., Coarse Feed up to 90 - 95% of the set weight and the balance 5 - 10% shall be fed in Fine Feed mode by which we can achieve optimum control of feeding and thereby improve the system accuracy. When the required set weight is achieved the feeding stops. The bag hooks are declamped automatically on weigh achieved and the filled bag is removed.

2) Second Model:

Filling range:- 500kg, 650kg 1000kg 1500kg and customer required capacity.

Jumbo Bagging with following models also available.

1. Jumbo Bagging with Vibratory table
2. Jumbo Bagging with Vaccumisation and dust collection system

Technical Specifications

·      The operator inserts the bag to the bag clamping chute and presses the foot switch. A pneumatically operated bag clamping arrangement will clamp the bag.

The controller automatically tares the gross weight of bag to obtain a Net Weight. The material is then fed into the bag by a Screw feeder.  The rate of feed from the screw feeder is controlled by a VFD

 

·      The controller compares the actual weight with the target weight settings, when the Main/Coarse feed setting is reached the screw feeder slows down and feeding continues in the Fine feed mode. 
The material is fed in the fine feed mode until the Final Weight minus In-Flight value is reached, after which the Screw feeder stops

 

·      Once the feeding is stopped a settling time (adjustable time, varies from 500ms to 2 sec) is given after which the end of batch is signaled, automatically the Totalizer and Bag counter is updated. 
An indicator lamp will indicate batch completion, after which the bag declamps automatically and conveyed to stitching machine

Our Bag Filling Machine consists of a Pneumatic gate under the storage hopper, weighing Hopper, Pneumatically operated valves, Discharge chute and a Microcontroller or Plc based Electronic Control Panel. We also provide Slat/Belt conveyor with stitching machine for the filled bags.
The operator sets the required quantity through the keypad of the electronic control panel. The operator holds the empty bag and presses a foot switch for clamping of the bag. On pressing start push button the material will flow from the storage tank to the Weighing Hopper through a pneumatically operated gate valve and it will close when the required set quantity is achieved. The pneumatic gate operates in fully open and partially open i.e. coarse and fine feed to get accuracy. The material filling will be done as per the set quantity.

Variants:
