Liquid filling machine is a computer to achieve human vision function, machine instead of the human eye to do the measurement and judgment, the use of photoelectric imaging system to collect the image of the controlled target, digital processing by the computer or a special image processing module, according to the image of the pixel distribution, brightness, and color and other information, size, shape, color and other identification. Vision technology contains light source illumination technology, optical imaging technology, sensor technology, digital image processing technology, mechanical engineering technology, detection and control technology, analog and digital video technology, computer technology, human-computer interface technology and other related technologies, which is the basic technology to realize the computer integrated system. Therefore, machine vision technology is applied to online inspection of packaging glass bottle quality, labeling, liquid loading, packaging batch number, etc., in order to realize rapid and automatic inspection and control of filling production.

Automatic filling machine acquisition can be triggered acquisition or continuous acquisition, the optical characteristics of the target object into two-dimensional information of the electrical signals, and then through the data acquisition card or the sampling and quantization function that comes with the acquisition equipment itself, it will be converted into a digital image. After that, the digital image is processed, including a series of steps such as image pre-processing, image enhancement, image segmentation, feature extraction, etc., and finally measurement and judgment are carried out through image analysis.

The software platform of the filling system consists of machine vision software and intelligent operation platform, and its main task is to realize program control for each hardware part respectively, and to realize the integration of each part of the hardware. At present, the widely used machine vision software mainly includes HALCON, EVISION and XCALIPER. HALCON8.0, which adopts German MVTec, is a powerful machine vision software that provides a comprehensive vision processing library, including all standard and advanced image processing methods, covering from different hardware acquisition images to advanced pattern matching algorithms.

The populated system provides a number of tools typically required in machine vision applications, such as Blob analysis, morphology, pattern recognition, measurement, data analysis, and other algorithmic manipulations or classifications. With the important features of rapid prototyping and open architecture, the inverter gland can be used to rapidly develop machine vision applications through an interactive programming environment, or to incorporate new arithmetic to merge its own vision functionality. The main component is liquid as the medium to be detected, and the level filling is realized by PLC control. Liquid level positioning filling is realized by weighing module, which not only makes the filling level reach a uniform horizontal position, but also simplifies the structure and reduces the maintenance cost of the machine in the later stage. Weighing filling machine is a new type of intelligent filling method that deserves to be widely promoted. The following is the function introduction of the filling machine system:

Product Setting - Storing the weight setting value of different products and the related filling triplets

Human-machine interface - the automatic filling scale can be easily calibrated at the weighing terminal; the filling number can be quickly set on the touch screen (optional).

Drop correction - automatically corrects the advance after each barrel to bring the next barrel closer to the target value.

Tolerance checking - checking the tolerance of the full pail, which can effectively prevent the spillage of materials.

Data statistics - including weight totalization, number of times totalization, can be connected with computer to realize data management (optional).

Multi-stage filling - can be divided into two-stage (fast/slow) or three-stage (slow/fast/slow) filling, greatly improving the filling accuracy.

Throttling device - effectively prevent the splashing phenomenon caused by the initial pressure of pumping when filling low-viscosity products.

Drip protection - high viscosity spray gun solves the drip phenomenon in the filling of high viscosity products, low viscosity spray gun with automatic oil dripping cup and air collecting cover device.

Bucket protection - Prevents damage caused by unaligned buckets when gun is lowered.

Filling modes - Filling modes can be designed for filling on the barrel hole, filling inside the barrel mouth and filling under the liquid surface, and the user can control the lifting rate of the spray gun to adapt to products with different foam levels (optional).

Solid structure - direct contact with the material part of 316 stainless steel, the balance of 304 stainless steel, carbon steel and so on.

Interlocking Safety - Various process interlocks ensure safe operation.

Easy to operate - filling systems are easy to learn and operate.

Flexible design - various forms of equipment and options are available according to the characteristics of raw materials and container size on site, compact structure.

Easy to install - just use expansion bolts to fix the equipment on the ground, connect the material pipeline, power supply and air supply and you are ready to fill.
