Automatic control system of continuous pressing machine

Abstract

The invention discloses an automatic control system of a continuous pressing machine. The system comprises an upper computer, a human-computer interface, a controller, a field slave station and input and output equipment, wherein the upper computer is arranged in a main control chamber; the human-computer interface is arranged in a field; the human-computer interface is respectively connected with the upper computer and the controller; the controller is respectively connected with the field slave station and the input and output equipment; the human-computer interface comprises a first human-computer interface, a second human-computer interface and a third human-computer interface; the controllers correspondingly connected with the human-computer interfaces are a mitre saw, a cooling line and a temporary stacking device respectively; and an instruction button used for sending a specification-replacing instruction is arranged on the upper computer. In such way, the automatic control system provided by the invention is reliable in operation, fiber plates with different specifications can be adjusted according to production conditions at any time, a production order can be sent at any time and automatic control can be realized according to order data, so that the specifications are replaced under the production condition that materials are continuously fed and the machine is not stopped, the continuity of the production is ensured, and the yield is improved.

Description

technical field [0001] The invention relates to a continuous press, in particular to an automatic control system for the continuous press. Background technique [0002] There are many manufacturers producing fiberboards with continuous presses all over the country. The production process is generally: the ground fibers are paved, pre-pressed, formed, hot-pressed by a press, cut by a miter saw, cooled by a cooling line, stacked and stored. [0003] When the domestic and foreign continuous presses are changing to different specifications, the control program is to stop the machine when the material is cut off, to discharge the plates of the previous specification from the production line, and then resend a new specification order, and then start the press for production. Changing the specifications every time will cause some head boards and tail boards, and a large number of unqualified bubble boards, resulting in greater waste and increased costs. [0004] In addition, accor...

AI Technical Summary

Problems solved by technology

In this way, every time the specifications are changed, some head plates and tail plates, and a large number of unqualified bubble plates will be caused, resulting in greater waste and increased costs.

[0004] In addition, according to the original design of the production line, the length and width of the boards are subject to certain restrictions. When customers need some fiberboards with special specifications, the original production equipment and software program design cannot meet the requirements because the length and width of the boards are not within the range of specifications. Production requirements, if you want to exceed a little length and width of fiberboard size can not be produced

[0005] Today's fiberboard industry has changed from the original supply shortage to the current state of saturation and excess. Customers have more and more stringent demands on the board, and often put forward many special requirements for the technology and size of the fiberboard. It is difficult for many fiberboard manufacturers to make such products.

[0006] In order to adapt to the market and increase market competitiveness, enterprises must find ways to produce the products required by customers, but the original production lines cannot meet the production requirements, and re-invest in new production line equipment in order to produce new products, which will require huge investment. Expensive, high cost, unaffordable for enterprises
