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
