Advantages and applications of non-contact on-line color detection system For Window Boxes For Essential Oil

The traditional color detection system uses the contact non - line way to detect the color of the product. The so-called contact type means that when detecting the color, the product or sample must be in close contact with the measuring instrument, otherwise it will not be able to get accurate color data. Non-on-line detection requires the product to be taken off the production line for detection, so the real-time color data on the production line cannot be obtained in time.

In contrast, the contactless online color detection system keeps a certain distance between the product and the testing instrument during color detection, and can also directly detect the product on the production line, breaking through the limitations of the traditional color detection method.

Generally, non - contact on-line color detection system includes color detection instrument, control software and auxiliary equipment. Color testing instrument is mainly used to test products to get the original color data. Software is used to control instruments and analyze data. Auxiliary devices are used to assist specific functions. For example, warning lights are used to show the color status of a product. When a red light flashes, the color difference is too large.

Advantages of non-contact testing

Traditional color detection requires applying a certain amount of pressure to the surface of the product under test, however, this often causes some damage to the product. In contrast, non-contact color testing does not cause damage or damage to the product or sample because it allows the product to be kept at a distance from the instrument.

Non - contact color detection system can detect non - flat products. Although with the help of some fixtures, the traditional detection system can also detect some non-flat products, but the accuracy of this detection method is not satisfactory. Obviously, the measurement range of the non-contact detection system is much wider, and the accuracy and accuracy of the detection has been greatly improved.

In general, in the detection of granular and powdered products such as color masterbatch, the instrument is required to detect through the glass. Because of the limitation of measurement area, the uncertainty of particle distribution and the influence of glass, the repeatability of measurement can not be guaranteed. Non-contact measurement, on the other hand, can avoid the influence of the container. At the same time, due to the larger measurement area, the influence of product arrangement on the measurement results can be significantly weakened, so that accurate color data can be obtained more easily.

In addition, the non-contact detection system can also detect wet samples, such as wet paint scraping samples. Such wet samples are difficult to measure with traditional instruments because direct measurement can contaminate or even damage the instrument. Non-contact measurement does not have this problem.

Advantages of online detection

Online detection can monitor the quality of each product on the production line in real time, enhance the color adhesion, not only conducive to reduce production waste, but also effectively improve production efficiency. "Online" here contains two meanings: first, it means that the detection system is installed on the production line, and second, it means that the detection system is connected to the control system of the production line.

Traditional color detection often lags behind production. When the color problem is detected, many or a large number of unqualified products have been produced, which leads to the waste of materials, and online testing can overcome this shortcoming. For example, a product inspection system can be installed on an extruder during the production of profiles used in construction. When the product reaches the detection position or the set time limit, the detection system will automatically detect the color of the product and obtain real-time color data in time. In this way, before cutting the product, we can master the advantages and disadvantages of the product color in detail. If there is a problem, we can adjust it immediately. In the testing process, the product does not have to leave the production line, nor does it have to stop the production line, so the time and labor costs are greatly saved.

A closed-loop control system can be formed by connecting the detection system with the control system of the production line. When the color data does not meet the requirements, the detection system can send a warning to the control system, or even stop production directly. The detection system installed on the fire proof board production line is a successful application case. The system will alert authorities when deviations from the product color exceed the warning value. If the product error exceeds the allowable range, the system will automatically issue an instruction to transfer the unqualified product to a specific area on the production line.

Another benefit of being connected to the production line's control system is that color data can be monitored remotely. Production management or quality management personnel can monitor the color of products in the office, or directly through the control system to give relevant commands and instructions. However, the traditional color detection system needs to communicate the color quality manually by means of E-mail or telephone, which is time-consuming and laborious, and the accuracy is poor.

Vericolor Spectro Contactless on-line detection System

The Vericolor Spectro Contactless on-line detection system developed by Aisley is one such cost-effective way to achieve high quality measurements. The successful development of the detection system also creates conditions for the wide application of non - contact on-line detection system in plastics and other industries.

The system includes VericolorSpectro spectrometer and VericolorSpectro software. Among them, the spectrophotometer is a 0/30 lighting measurement geometry, using full spectrum LED lighting, measuring area of 25.4mm, the average difference between stations is 0.3DE*, weight is only 2.81kg. The Vericolor Spectro software is Windows-based, easy to install, easy to use, and the data generated can be recorded as EXCEL files.

The dual-beam 31-channel system has high accuracy with an average short-term repeatability of 0.03DE*. Due to the patented light source design, the system is not sensitive to incandescent, fluorescent, and sodium ambient light, so there is no need to change the lighting conditions of the plant. The operating temperature range of the system is 0~50℃, the measuring distance is 10.16cm, and the deviation of ±5.0mm is allowed, so it is less affected by the distance fluctuation. It is worth mentioning that the system has passed the NEMA-4/IP67 standard audit, is dust and pollution resistant, and can withstand shock and vibration. In addition, the system is not only robust in design, but also easy to maintain, requiring little special maintenance other than daily cleaning and monthly calibration.
