In the production of tinplate three-piece cans, for some reason, the so-called “falling cans†(upside down on the cans) occurs. The reason for the inverted cans occurs mainly in the process of cutting and welding the iron sheets in different processes. When the wrong orientation is caused due to human factors such as handling, the inverted cans are produced. The inverted cans should be picked out only by the artificial eye. Inevitably there will be omissions.
The canning problem has been plaguing the can making industry. For a long time, many people in the industry are constantly exploring, researching and testing inverted cans detection technology. In foreign countries, in order to prevent the phenomenon of “back cansâ€, image detection is used more often, but it is not widely adopted because it is subject to high cost. Therefore, professionals are still developing more cost-effective systems. Our company has also been looking for and comparing the prices of inquiries about effective ways of detecting inverted cans. However, there has not been a set of feasible solutions before.
In response to this problem, our company is headed by the director of the canning factory Zhang Weinan and extensively collects relevant technical field information. After selecting and analyzing the main components, the relevant personnel of the can making technology room were discussed and the amplifier and sensing were determined. The head is combined with a detection sensor to detect the inverted tank. By comparison, this system is much more economical and practical than the use of image detection heads to detect inverted cans.
The working principle of this system is: according to the difference between the color of the upper and lower parts of the three-piece can body, the color value is sensed to distinguish whether or not the “can drop†occurs. After the amplifier sends the signal, the solenoid valve opens the air path. Push the pouring tank into the assembly line.
After a good solution was determined, the canning equipment technical department immediately organized personnel to carry out program design, and completed a series of work such as parts procurement, system development, installation and debugging within a short period of one month.
During the actual installation and debugging process, Luo Xiaosheng, the can making equipment technical room, used his professional knowledge to skillfully use the performance of the sensor head, so that the two sensors had to be used to streamline the process into a single sensor head and realize the relevant functions. One-third of development costs. Next, several sets of relevant control circuits were designed for the system. Finally, a relatively concise and effective circuit control scheme was selected. The initial debugging achieved a preliminary effect.
This set of systems was put into formal installation and debugging under the active cooperation of the beverage can manufacturing department. Shen Xinhua's manager was rich in experience. He simplified the original method of using a cylinder imitation welding machine to make cans, and used the imitation leak detection method. Use compressed air directly to pick up unqualified tanks.
A good idea, coupled with the pursuit of intentions, a simple, practical inverted cans testing cans system in the beverage cans line test debugging success, and less effective investment. The facts prove once again that technological innovation is endless, and there are many opportunities for innovation in our work. It depends on whether we can be aggressive and aggressive, and can climb the peak of technology while also realizing our own value.
