The batcher with the belt feeder

The weight automatic batcher for free-flowing materials SWEDA DWS-301-50-5 is intended for batching of free-flowing lump materials in bags of the open type.

By means of the weight batcher SWEDA DWS-301-50-5 it is possible to pack up in sewing (open) bags (paper, polypropylene, jute) coal, crushed stone, briquettes and other lump materials with the size of fraction to 50mm.

The batcher includes mechanical and measuring-controlling parts.

The mechanical part includes: a receiving hopper(1), a belt conveyor(2) with a receiving neck(3), a guiding neck(4) with an aspiration cover, a weight nech of the batcher(5) with a load cell and a gear of the bag clamp and a common cradle(6).

The measuring-controlling part includes a load cell, a weight processor PW-310(7), a cabinet(8) with a frequent converter and an electropneumatic actuator package.

Optionally the batcher can be completed by a level indicator, preventing pour off the material from the receiving hopper.

The operator hangs a bag on the weight neck. Thus the limit switches are actuated and the bag is clamped by the special gear, controlled by a pneumatic actuator. The batching material from a receiving hopper arrives self-flowing in the neck of the belt feeder, from which by a moving belt it is displaced to the weight neck and further in the bag. The weight processor PW-310 controls all process of batching, including control of the material feed, speed of motion of the feeder belt, measuring of weight of the material in the bag.

Capacity of the complex - to 200 bags/hours, depending on the properties of the material and qualification of the operator.

о Advantages:

Convenience of maintenance:

- a semi-automatic mode of operation (the operator only hangs a bag);

- exclusion of dusting at the expense of the cover with a fitting pipe for aspiration system;

- the standard interface of link with the computer for account of doses and registration of events;

- the convenient user menu in the weight processor.

Ample opportunities:

- high accuracy ±0,5 - 0,1%;

- adjusting dose setting - from 25 to 50 kg;

- high capacity (to 200 bags/hours);

- automatic adjustment of the settings "rough-precise" of batching;

- ample opportunities of the display of the weight processor (indication of the batching mass of the product, the amount of the doses, the accruing total for a shift and a season etc.)

The weight batcher for free-flowing materials SWEDA DWS-301-50-5 with the bag sewing line SWEDA LZM can be used as a part of a packing complex.

  • principle of the product weighing tensometric-electronic, the control mode-electropneumatic;
  • filling-up of the bag with the material - by flow of the falling material;
  • control of the batching process - automatic;
  • the batching process is accompained by the indication on the digital board of mass of the batching material and the total of doses by the accruing total;
  • the batcher has an out on the exteal recording devices by the standard interface RS-485;
  • bag hanging is made manually by the operator;
  • bag dropping is executed automatically;
  • for batcher embedding in systems of the information gathering the weight processor PW-310 ensures data transmission to peripherls (a PC or a portable board);
  • PW-310 ensures forming of the data joual for saving of the information about the common total, and also date and time of recording of this information in the joual and the joual of events for saving of the information on the executed processes by the maintenance personnel, and also recording of all errors;
  • saving of totals and settings of the batcher at s n cutting off the supply voltage is ensured;
  • PW-310 of the batcher has the selective (Russian/ English) interface of the user, firmware system of tests, password protrection of settings from casual or deliberate measuring, blocking of the batcher operation at corruption of setting data, convenient simple system of calibration of the weight-measuring device.
