Combination Weigher: Accurate Weight Matching Solutions | SameGram
In the high-speed world of modern manufacturing, precision is not merely a goal; it is a fundamental requirement for profitability and brand reputation. Among the various technologies driving this precision, the Combination Weigher stands out as a cornerstone of automated packaging. By utilizing an intelligent combination algorithm, these systems have transformed how industries handle everything from delicate snacks to fresh produce, ensuring that every package meets an accurately matched target weight.
At SameGram, we specialize in bridging the gap between raw production and perfect portions. Our systems are engineered to eliminate the "giveaway" problem—where overfilling leads to lost revenue—while maintaining the lightning-fast speeds required by today’s global supply chains.
1. Authoritative Definition: What is a Combination Weigher?
A Combination Weigher, often referred to as a multihead scale or a selective scales system, is a high-precision industrial weighing machine designed to divide bulk products into specific, pre-determined increments. Unlike traditional linear scales that weigh a single batch at a time, a combination weigher uses multiple weighing heads (usually 10 to 24) to calculate the best mathematical combination of weights to achieve a target total.
The core value of this technology lies in its intelligent combination algorithm. By processing the weight data from various platforms simultaneously, the system identifies the most accurate subset of products to discharge, ensuring that the final package weight is as close to the target as possible, often within a fraction of a gram.
2. How It Works: The Intelligence Behind the Scale
The operation of a SameGram Combination Weigher is a marvel of mathematical efficiency. To understand its value, one must look at the sequence of events that occurs in milliseconds:
1. Distribution: Product is put on the weighing platform of the machine.
2. Individual Weighing: Each weighing head (such as those found on our Combination Weigher SBW-2512B12 model) captures the weight of the product currently sitting on its platform.
3. The Algorithm at Work: This is where the magic happens. If you have 10 platforms, each with a slightly different amount of product, the computer doesn't just pick one. It calculates thousands of possible combinations. For example, it might find that the weights from heads 2, 5, 8, and 10, when summed, perfectly match the 500g target.
4. Discharge: The selected hoppers open simultaneously, and the product is transported to the packaging machine (VFFS, tray sealer, or jar filler).
By integrating this system into an automated line, manufacturers move from "estimated filling" to "guaranteed accuracy."
3. Technical Parameters: The Standards of Precision
When selecting a Combination Weigher, understanding the technical boundaries is crucial for ensuring the machine fits your specific production needs. SameGram systems are designed with versatility in mind, particularly for small to medium-portion applications.
| Feature | Range / Specification | ||
Weighing Range | 10g – 2000g (Depending on model) | ||
Accuracy | ±0.1g to ±3g | ||
| Max Speed | Up to 30 portions per minute | ||
| Material | Food-grade SUS304 Stainless Steel | ||
| Control System | 7-inch or 10-inch Industrial PLC Touchscreen | ||
For specialized tasks, such as our Small Portion Combination Weigher SBW-2512B12, the focus is on handling delicate items with extreme care while maintaining a compact footprint.
4. Application Scenarios: From Field to Package
The versatility of the Combination Weigher allows it to excel in diverse sectors. However, one of the most compelling use cases is in the fresh produce industry.
Case Study: Automated Vegetable Packaging
In a recent integration, SameGram deployed a weighing system for a large-scale cucumber packaging facility. The challenge with cucumbers (and similar long-form vegetables) is their irregular weight and shape.
In this setup:
● The Combination Weigher acts as the brain of the line.
● The system uses its intelligent combination algorithm to select cucumbers that collectively meet the weight requirement for a multi-pack.
This level of automation reduces labor costs by up to 60% and increases throughput by nearly 40%. For a visual demonstration of this process, watch our system in action here.
5. Industry Standards & Regulations
To operate in global markets, especially in food and pharmaceuticals, equipment must adhere to rigorous standards. SameGram ensures that every Combination Weigher we manufacture meets:
● CE Certification: Ensuring the machine meets European safety, health, and environmental protection requirements.
● IP65 Waterproofing: Essential for food processing environments that require frequent wash-downs to maintain hygiene.
● FDA Compliance: All contact parts are made from materials certified for safe food handling.
Our commitment to these standards is a core part of our corporate identity. You can learn more about our quality control processes at About Us.
