Semi-automatic weighing and packing line type WB/T

It was market demand that induced us to design the semi-automatic weighing and packaging line of the WB/T type, which combines in itself precision of weighing, relatively low price and simplicity of operation.

The WB/T type line is a semi-automatic appliance for weighing and packaging loose / granulated products with the use of open type bags.

The presented line is equipped with a weighing system mounted on the mouthpiece, called a gross system, which denotes that the product is dispensed with the use of a belt conveyor to the packaging. Owing to the above, we achieved considerable cleanness of the entire system, which is of significance for the quality of production.

The WB/T type line can reach the capacity of up to 280 batches per hour.

Basic subassemblies of the appliance:

  • Line supporting structure with a service platform
  • Electronic batching scales of the gross type
  • Belt feeder
  • Open mouthpiece
  • Belt conveyor for transporting bags
  • Belt conveyor height adjustment system
  • Bag top guiding system
  • Single-thread stitcher
  • Side belt conveyor collecting bags with a system for overturning bags
  • Clear control system based on Siemens PLC controller with a touch panel
  • Applied SEW or LENZE drives / servodrives

Optional equipment:

  • System for folding bag top
  • System for applying crepe tape
  • System for sucking out product in a bag
  • Filled bag vibration system
  • Feeder cleaning system
  • Impulse or continuously heated sealing unit
  • Double-thread stitcher
  • Balancing container located above the scales

Basic technical parameters:

  • Maximum batch weight: 50kg,
  • Minimum batch weight: 10kg,
  • Line capacity: up to 280 batches/hour (depending on the product characteristics and batch size),
  • Bag type: open bags, multilayer paper bags (up to 4 layers), envelope-shaped bottom bags without side folds are recommended, PE foil bags, PP polypropylene coated bags,
  • Bag width: 450 – 650mm,
  • Bag length: 600 – 1100mm
  • Power supply: 3 x 400V 50Hz,
  • Power requirement: max. 4.5kW,
  • Compressed air supply: 5 – 10bar,
  • Compressed air consumption 200-400Nl/min,
