Multihead weighers (also referred to as combination scales) play an essential role in modern packaging technology, helping companies ensure efficiency and accuracy when measuring product dimensions. As industries expand and consumer expectations rise, so has the demand for precise product measurement; multihead weighers serve an indispensable function across various sectors that enables automation packaging processes while simultaneously minimizing errors while speeding them up – this guide offers a comprehensive overview of multihead weighers in all their forms – outlining their structure, functionality, advantages of selection as well as applications across industries.
What Is a Multihead Weigher?
A multihead weigher is an advanced technological solution used mainly in food, medical, and other consumer product industries to package product quantities accurately. While traditional scale-based methods rely on single scales alone for accurate weighing measurements, multi head weighers use multiple weighing heads working simultaneously in concert for accurate yet quick measurements – an advantage over single scale methods which could hinder packaging efficiency without sacrificing accuracy in modern production lines. It enables efficient product packaging without any loss in accuracy, making this an indispensable tool in modern production lines!
Multihead weighers combine information from several scales simultaneously in order to quickly arrive at an exact weight for packaging snack food, grains or pharmaceutical products. They offer unsurpassed speed and precision when used.
Structure of Multihead Weigher
To appreciate a multihead weigher is essential in fully appreciating its functionality. These machines consist of various key components which all play important roles during weighing and packaging processes.
- Intake Funnel: An intake funnel serves as the entryway to any product being weighed, efficiently leading it into the weighing system without creating clogs and maintaining steady material flow.
- Top Cone: Situated above linear vibrators, the top cone directs product evenly down onto linear vibrators for distribution across vibratory channels and achieve uniform distribution – essential in accurate measurement. This feature ensures uniformity that contributes to uniform measurement results.
- Linear Vibrators: These components aid the movement of product towards feed hoppers by using controlled vibrations to promote consistent product flows, thereby minimizing jams and providing even distribution.
- Feed Hoppers: Feed hoppers serve a purpose that mirrors its name: collecting product and transporting it directly into weight hoppers for weighting or assembly into various configurations. Each feed hopper holds specific amounts that can be combined as desired in different weight hoppers for convenient weighted assembly and weighing.
- Weight Hoppers: As the heart of multihead weighers, weight hoppers feature high-precision load cells to weigh products accurately with pinpoint precision. By working simultaneously as multiple weigh hoppers allow for fast weighing and selection processes.
- Actuator: An actuator plays an essential part in managing the discharge of weighed products from their systems. It determines the precise moment when each piece leaves the system for downstream machinery integration.
- Discharge Chute: The discharge chute feeds accurately-weighed product directly to a packaging line for immediate filling of bags, boxes or containers with accurate fill levels. Depending on product and packaging needs, its design may differ accordingly.
- Timing Hopper: This component ensures that product weighed on multihead weighers is delivered to their packaging machines at exactly the appropriate moment and acts as an important buffer between themselves and packaging machines. In doing this, they allow efficient operation between combination weigher operations. Packaging machines allow efficient operations without interference from multihead weighers.
- Touch Screen: As the primary user interface of multihead weighers, touch screens enable operators to set parameters, track performance and make any necessary changes or modifications as required. Modern systems offer user-friendly control features to improve usability and efficiency.
- Main Frame of Multihead Weigher: As the cornerstone of multihead weighers, the main frame provides structural support and ensures stability during operation while securely housing various components.
How Does a Multihead Weigher Operate?
A multihead weigher’s operation involves several sequential steps designed to enable precise measuring and packaging of products:
- Conveyor loading: Bulk products are conveyed via belt conveyor or bucket elevator and then guided to the top cone.
- Vibratory Distribution: The top cone directs the product into the linear vibrators, which send controlled vibrations to distribute the product evenly across the involved feed hoppers.
- Feeding: Each feed hopper receives a controlled amount of product, preparing for the weighing process.
- Weighing: The weight hoppers utilize load cells to measure the exact weight of the product within. This simultaneous weighing provides multiple weight combinations for fast processing.
- Combination Selection: The system’s software identifies the ideal combination of weights that meet the predetermined target. This computation occurs at high speed, only taking a fraction of a second.
- Discharge: Once the optimal weight combination is determined, the actuator signals the discharge chute to release the weighed product into the timing hopper.
- Timing Hopper Management: To prevent disruptions of production flow and ensure timely release of product into packaging machines, timing hopper management ensures product is released at precisely the appropriate moment into packaging machines.
- Integration With Packaging: Once weighted products enter the packaging line, they are distributed into bags or other containers ready for distribution.
