Cardboard warping latest solution (below)

Closed loop system control

At present, most carton manufacturers rely not only on the operator's subjective determination of corrugated board warpage but also on how to control and reduce the warpage of the board. This is also done by the operator controlling the machine. The operator solves the cardboard warpage problem by adjusting the parameters, and these parameter adjustments also have a strong subjectivity. The operator on the stacker determines the value of the parameter adjustment according to the main observation evaluation. Whether or not the operator can successfully control and reduce the degree of board warping depends entirely on his work skills, experience and training proficiency. Even in the best corrugated box manufacturing plants, the judgment of the degree of warpage of corrugated board is uneven. Now, these board warping judgments, which were previously achieved by the skill and labor of the operator, can be replaced by the feedback data provided by the Svncro ProfileSPl 200 system. Syncro Profile SPl200 system can directly control the parameters that cause board warpage, which can guarantee the production of flat corrugated cardboard, reduce dependence on personnel operation skills, save labor resources, help redistribution of factory labor resources, make cartons The factory benefits to the maximum extent.

In order to minimize the warpage of the board, the Syncro Profile SPl 200 system is optimally integrated with the control system of the entire corrugated board production line. The angle parameters of all the warp arms, the water content and temperature of the facing paper, and the glue gap Both settings and machine speed can be measured and recorded. Data information produced in real-time production can also be combined with control algorithms. Reduce the number of returns to improve customer satisfaction

In the face of the corrugated box market in most countries of the world, there is a phenomenon of severe saturation and thinning of profits. How carton manufacturers survive in the market and win new customers sometimes requires more than just reasonable prices, but also needs other advantages. Such as cardboard quality, timely delivery and customer satisfaction. Many board manufacturers have severely damaged customer satisfaction due to the production of warped cardboard. With the Syncro Profile SPl200 system, board warpage can be limited to an acceptable range before the board leaves the cadre equipment, transports it to the factory, and arrives at the customer's warehouse, thereby ensuring customer satisfaction and retaining “returning customers”. The maximum warpage value can be printed on the transport document as a sign of factory quality control, which can effectively reduce the number of returns, logistics costs and the cost of taking remedial measures, thereby greatly improving customer satisfaction.

Whether it is the warping measurement function and display system provided by the Syncro Profile SPl200 system or the use of an integrated system with a closed-loop feedback system to automatically control the board warping problem to a minimum, the system is of great significance to corrugated board manufacturers. . With the Syngr0Profile SPl200 system, a full and detailed understanding of the board warpage in the production process can be obtained. The inspection tool helps analyze the cause of warpage caused by the board and helps to solve the board warpage problem in the production process. In a closed-loop system, the parameter settings that cause the board warpage can be automatically controlled. All this shows that the system can be very effective in reducing the degree of board warping, reducing the dependence on staff skills and participation. At least carton manufacturers can recover 200,000 pounds per year in cost.

The warpage detection function and display system can be installed in one day, with very little impact on the normal production of the corrugated cardboard production line. The Syncro Proile SPl200 system can operate in conjunction with systems that can interface with existing inspection systems, record and analyze board warpage data.
