Pre-weighing and suspended tolbag

The pre-weighing and overhead Tolbags (weighing and filling systems for Big-Bags), from Toledo do Brasil, is used for weighing and filling granulated products directly into Big-Bag type bags up to 1200 kg, with two different forms weighing the product, either directly in the weighing bucket, by pre-weighing, or in the Big-Bag itself, in a suspended form, whereas in the pre-weighing Tolbag, as the dosing is carried out in a bucket, it becomes possible to increase the number of Big-Bags filled per hour, as the time used for dosing in the bucket is also used for removing and placing the Big-Bag in the filling position.

The single batch pre-weighing Tolbag is intended for weighing and bagging granular products, where there is no limitation of the vertical space, which is why it has a higher productivity than the weighing of the batch pre-weighing Tolbag, necessary for weighing and bagging of granulated products, where there is limited vertical space.

The suspended Tolbag comprises a dosing system activated by pneumatic cylinders with double stage, ensuring 0.1% accuracy, which provides reliable weighing, without lack or excess of product, in addition to having the control panel with buttons and logic for feeding a product with double feeding stage (fast and slow), keyboard in sealed blanket for programming setpoints together with the measurement of the equipment and digital filters to control the stabilization of the weighing.

Pre-weighing Tolbagsingle batch

It is intended for weighing and bagging granulated products, where there is no limitation of vertical space. For filling a Big-Bag, one single batch is sufficient.

Suitable for Big-Bags of different formats with dimensions from 900 to 1100 mm wide by 1400 to 1500 mm high.

Example: one single batch is needed to fill a 1200 kg Big-Bag with crystal sugar.

This version has a higher productivity compared to batch weighing.

The pre-weighing Tolbag is designed for products with good flow. Examples: sugar, grains, plastic pellets, etc.

Pre-weighing Tolbagby batches

It is intended for weighing and bagging granular products, where there is limited vertical space. As 3 or more batches are needed to fill a Big-Bag, the dosing bucket has a smaller volume when compared to a single batch.

Suitable for Big-Bags of different formats with dimensions from 900 to 1100 mm wide by 1400 to 1500 mm high.

Example: 3 batches are needed to fill a 1200 kg Big-Bag with crystal sugar.

FILLING CAPACITIES

Considering the weighing and filling process of Big-Bag of 1200 kg of sugar.

  • Batch pre-weighing Tolbag: 30 to 35 Big-Bags/hour;
  • Tolbag pre-weighing by single batch: 40 to 50 Big-Bags/hour;
  • Overhead Tolbag: 30 to 40 Big-Bags/hour;

These productions are only estimates, disregarding the decrease in productivity of the operator during the changes of Big-Bags, constant feed flow, in addition to product variations, such as granulometry, humidity, density and behavioral variations of the product.

Overhead Tolbag

In this version, the Big-Bag is suspended on the hooks, supported by 4 pneumatic cylinders. There is no pre-weighing bucket and the product is dosed and filled directly into the Big-Bag.

Suitable for Big-Bags of different formats with dimensions from 900 to 1100 mm wide by 1400 to 1500 mm high.

For products that need to be compacted in the filling process. The accommodation of the product is done automatically through pre-programmed shocks of the Big-Bag against the floor or pallet during the filling and weighing process.

The Big-Bags can be removed using a trolley on rails (optional), forklift, pallet truck or motorized conveyor.
