Problems solved by technology
Since the existing gravure printing equipment does not have any records of the products in the warehouse and manual sampling products and is often subject to manual intervention, it is easy to cause confusion due to human factors. Ensure that the number of every 10,000 products is absolutely accurate, making it very inconvenient for managers to view and use the sampling data

Embodiment Construction
[0021] The present invention comprises the following steps: 1) The host PLC sends signals such as paper feeding, closing pressure, and paper feeding stop to the Siemens S7-200PLC of the coding system (that is, the coding PLC), and the S7-200PLC simultaneously receives the version paper detection signal, and By cooperating with the angle pulse signal sent by the encoder, two CCD cameras are controlled to collect the numbers of large sheets of products at the set angle, and automatically record the numbers of all products in the printing process. 2) The code recognition industrial computer compares the number image collected by the CCD camera of the paper delivery part with the number image collected by the CCD camera of the paper delivery part through the internal program through data shifting and other calculations, and verifies again to ensure the accuracy of the number. 3) The normally printed large-sheet products fall into the first warehouse or the second warehouse under th...

The invention discloses an automatic controlling and recording method for gravure products falling into storehouses. A code recognition system and a host PLC (programmable logic controller) are adopted. The code recognition system comprises a code recognition PLC and an industrial personal computer; a color area array CCD (charge coupled device) camera is arranged on a paper feeding part and a paper collection part of a gravure press; and coders connected coaxially are arranged on a paper transferring drum. During printing, the code recognition system determines the type, the number and the position of each product in the gravure press according to the information collected by the devices and the running information sent by the host PLC, sends a discharging signal and a signal for sending paper into three storehouses to the host PLC according to the information, receives a falling signal sent by the host PLC, and automatically records the numbers of the products falling into each storehouse. With adoption of the method, the numbers of the products are automatically recorded; the products are automatically discharged into the storehouses; and the paper and the products are automatically separated, so that management persons can check and use the randomly-checked data conveniently. Therefore, the information tracing and the responsibility implementation are carried out more accurately and efficiently, and the digital safety control capability is improved surely.
Description
technical field [0001] The invention relates to a method for precisely controlling gravure printing products falling into bins and automatically recording the product numbers falling into each paper receiving bin, belonging to the technical field of printing. Background technique [0002] The particularity of the banknote printing industry requires enterprises to achieve effective and precise control of each gravure product, and to automatically record the information of each product. When the gravure printing equipment is running, the paper passes through the paper feeding part and the printing part to the delivery part in turn, and finally falls into three bins under the control of the paper release cam in the delivery part. The first and second bins are paper receiving bins, and the third bin is for sampling. and waste bins. Since the existing gravure printing equipment does not have any records of the products in the warehouse and manual sampling products and is often s...
