Source of multihead weigher

In the 1970s, the Japanese Agricultural Association asked weighing companies to weigh green peppers. In Japan, green pepper is usually packaged in bags in the form of quantitative packaging in supermarkets, if each bag of green pepper quantitative value is 120 grams, it is very difficult to fill 120 grams. As a single green pepper weight is heavier, and the difference is larger, less related to the interests of consumers, more related to the cost of the enterprise. The traditional way is manual weighing, that is, weighing on a static electronic scale, add up to 115 grams of green pepper one by one, and then it is almost impossible to find a 5 grams of green pepper to add, you must take a smaller green pepper from 115 grams, and add another larger green pepper. If the weight is much more than 120 grams or less than 120 grams, the above work needs to be repeated, so the weighing efficiency is very low, and it is difficult to achieve close to the target weight (quantitative value) results. After a lot of investigation and research, the technical personnel successfully solved the weighing problem of green pepper by using the combination weighing principle. Some large food enterprises will be its designated equipment.

Composition of multihead weigher

The basic composition of the combined scale is: main vibration plate, main vibration machine, line vibration plate, line vibration machine, hopper, weighing bucket, chute, hopper (optional), stepping motor, driving board, module conversion device, main control board.

Working principle of multihead weigher

1. The material is sent to the storage hopper by the material conveyor. When the material is added to the pre-set horizontal position, the electronic eye on the side of the storage hopper detects and sends out a signal to make the conveyor stop feeding until the material level on the storage hopper drops to the preset horizontal position, and then the electronic eye sends out the feed signal;

2.The material in the storage hopper, through the vibration of the main vibration machine to make the material from the main vibration plate evenly into the line vibration plate, to feed the line vibration plate;

3.The vibration of the line vibrator causes the material to be discharged from the line vibrator and into the hopper for storage;

4.When the weighing bucket completes the last weighing and emptying, the upper hopper is opened to make the material enter the weighing bucket for weighing. The output signal is transmitted to the motherboard of the control device through the lead wire. The CPU on the motherboard reads and records the weight of each weighing bucket, and then selects the combination weighing bucket closest to the target weight through calculation, analysis and combination.

5.When the feeding signal is allowed, the CPU issues a command to start the driver to open the selected weighing bucket, the material is sent through the chute into the hopper or directly into the packaging machine, and the feeding signal has been sent to the packaging machine to complete the weighting packaging system.

In the world of food packaging, accuracy, speed, and efficiency are crucial elements for success. To meet these demands, the industry has witnessed the rise of a remarkable technology called the Multihead Weigher. It has revolutionized the way products are weighed and packaged, offering unparalleled precision and productivity. In this blog post, we will delve into the workings of multihead weighers and explore their impact on the food packaging industry.

What is a Multihead Weigher?

A Multihead Weigher is a cutting-edge weighing system that employs advanced technology to accurately measure and distribute a wide variety of food products. It consists of several independent weighing heads, each equipped with its own load cell. These heads work together in synchronization, allowing for high-speed weighing and packaging operations.

How does it work?

The multihead weigher operates through a three-step process: weighing, calculation, and distribution. First, the product is fed into the multihead weigher, where it is divided into individual portions by the weighing heads. Each head simultaneously measures the weight of its designated portion using load cells and sends the data to a central processing unit.

Next, the central processing unit calculates the optimal combination of portions to achieve the desired target weight. It configures the distribution paths to ensure the accurate allocation of portions, taking into account factors such as the characteristics of the product and the packaging requirements.

Finally, the calculated portions are distributed to the packaging machine, which fills the individual packages rapidly and precisely. This seamless process ensures that each package contains the correct weight, minimizing product giveaway and maximizing efficiency.

Advantages of Multihead Weighers:

Precision: Multihead weighers are renowned for their exceptional accuracy, even with complex products like mixed nuts, snacks, or frozen foods. This accuracy results in consistent product quality and customer satisfaction.

Efficiency: With their high-speed weighing capabilities, multihead weighers significantly increase productivity. They can handle large volumes of product, reducing production time and labor costs.

Versatility: Multihead weighers are adaptable to various food product types, sizes, and shapes. They can handle both dry and wet products, making them suitable for a wide range of applications in the food packaging industry.

Hygiene and Food Safety: Multihead weighers are designed with food safety in mind. They feature smooth surfaces and removable parts for easy cleaning, promoting hygiene standards and reducing the risk of contamination.

Impacts on the Food Packaging Industry:

The integration of multihead weighers has had a transformative effect on the food packaging industry. It has brought about increased operational efficiency, improved packaging quality, and reduced product waste. The precise weighing and distribution capabilities of multihead weighers have also enabled manufacturers to meet stringent regulatory requirements and maintain compliance with industry standards.

Furthermore, the automation and speed provided by multihead weighers have facilitated streamlined production processes. This has allowed companies to scale their operations, penetrate new markets, and meet the growing demand for packaged food products.

Conclusion:

The advent of multihead weighers has revolutionized the food packaging industry, offering unparalleled accuracy, efficiency, and versatility. As technology continues to advance, we can expect further enhancements in multihead weighers' capabilities, enabling manufacturers to meet evolving consumer demands and achieve greater success in the competitive market.

Whether it's ensuring the consistent weight of a bag of chips or accurately portioning delicate confectionery treats, multihead weighers will continue to play a crucial role in the future of food packaging.
