Description

Device and method for detecting missing strips in sub-brand weighing and intelligent inkjet code control

technical field

The invention relates to a device and method for sorting cigarette cases and spraying codes in the packing and sealing process in the tobacco industry.

Background technique

At present, in the tobacco industry, after cigarettes are packed, it is necessary to check whether the packaged quantity is qualified. The usual inspection method is to install a weighing scale on the conveyor belt of the cigarette box, and judge which cigarettes are qualified in the batch by testing the weight of each box of cigarettes, and remove the unqualified cigarette boxes, and the qualified ones can be shipped out by spraying codes .

But there are following deficiencies in this device for judging whether the smoke box is qualified according to the weight: 1. the conveying line of the smoke box is a mixed conveying line, and there are often smoke boxes of multiple specifications and packages, and there must be differences in its weight, so that it is not qualified If the smoke boxes are rejected, the weighing range of the weighing scale needs to be set wider. Although the qualified smoke boxes will not be rejected, it will also reduce its sensitivity, and the smoke boxes with reduced weight after a large number of missing bars will leak. 2. The foreign party requires that the smoke boxes for export cannot be coded, but the existing conveying line is a mixture of export products and domestic products, and the inkjet printer cannot It is the export smoke box that makes the judgment and will still spray. For this reason, the export smoke box must be transported in a centralized manner, which will not only cause difficulties in production, but also cause waste of inkjet printers by mistake.

Contents of the invention

The purpose of the present invention is to solve the problem that the equipment used in the packing and sealing process in the existing tobacco industry cannot identify the specifications of the cigarette box, resulting in the common phenomenon of lack of strips in the cigarette box, and the frequent phenomenon of misprinting by the inkjet printer. The device and method for identifying the specifications of the smoke box by the barcode on the barcode, which has a simple structure and is easy to use can effectively improve the recognition accuracy and reduce the phenomenon of missing bars. Will cause false spraying, reduce costs and other advantages.

In order to achieve the above object, the present invention adopts the following technical solutions: a sub-brand weighing missing strip detection and intelligent inkjet code control device, which includes a weighing device installed on the conveyor belt, a printing device behind the weighing device, etc. Its features are: there is a barcode reader on the conveyor belt in front of the weighing device, and the barcode reader is connected to the control device; at the same time, the control device is connected to the weighing device and the printing device respectively, and the conveyor belt between the weighing device and the printing device There is a rejector on it, which is also connected to the control unit. The weighing device is a dynamic belt scale. The printing device is an inkjet printer, which is installed on the conveyor belt behind the dynamic belt scale. The barcode reader has a CCD photosensitive head, which is installed above the conveyor belt. The control device is an industrial computer.

A method for detecting the absence of a sub-brand weighing bar and intelligently spraying codes, which includes the following steps:

a. The barcode reader reads the barcode information of the cigarette box on the conveyor belt, and sends the information to the industrial computer;

b. The smoke box arrives at the dynamic belt scale, and the weight information is sent to the industrial computer after being weighed by the dynamic belt scale;

c. The industrial computer determines the specifications of the smoke box and the weight range of qualified products according to the barcode, and compares the weight information sent by the dynamic belt scale with the weight range of qualified products;

d. If the weight of the smoke box is within the weight range of qualified products, it will be sent to the inkjet printer after leaving the dynamic belt scale;

e. If the weight of the smoke box exceeds the weight range of qualified products, it will be removed by the rejector after leaving the dynamic belt scale;

f. According to the obtained barcode information, the industrial computer controls the inkjet printer to spray the corresponding content on the smoke boxes that need to be coded, and not to spray codes on the smoke boxes that do not need to be coded.

The present invention utilizes the bar codes that have been included in the international standard products at present, and the cigarette boxes of various specifications correspond to different bar codes. A barcode reader is installed on the conveyor belt that transports the cigarette boxes, and it sends the barcode information of each cigarette box to the industrial computer; when the smoke box passes through the dynamic belt scale, the belt scale sends the weight signal of the smoke box to the industrial computer, and the industrial computer Then, according to the set weight value range corresponding to each standard smoke box, it is judged whether the weight of the smoke box is qualified, and the qualified smoke box is sent to the inkjet printer, and the inkjet printer sprays the corresponding information under the control of the industrial computer The export products that do not need to be sprayed are no longer sprayed, thereby reducing the waste caused by mis-spraying; unqualified smoke boxes are removed after leaving the dynamic belt scale.

The invention has the advantages of simple structure, high recognition accuracy, small error, high degree of automation in use, not only reduces the cost of use, but also facilitates production transformation.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

Among Fig. 1, install dynamic belt on conveyor belt 7 and say 3, it is the SB60.2 type that Swiss Mettler company produces. Smoke box 6 is arranged on the transmission belt 7 ahead of dynamic belt scale 3, and the top of conveyor belt 7 is a barcode reader 2, which has adopted a CCD photosensitive head, which has the advantages of high precision and accurate recognition. The barcode reader 2 is connected with the industrial computer 1, and sends the read barcode information to the industrial computer 1, and the industrial computer 1 is a PIC667 type. The dynamic belt scale 3 is also connected with the industrial computer 1, and it sends the measured weight information of the smoke box 6 to the industrial computer 1. The industrial computer 1 selects the weight value of the specification according to the product specification represented by each barcode, and then compares the weight signal sent by the dynamic belt scale 3 to determine whether the smoke box is qualified, and the qualified product is sent to the inkjet printer 5, The inkjet printer 5 is connected with the industrial computer 1, and the industrial computer 1 controls the inkjet printer 5 to spray the corresponding information according to the information of the bar code or does not spray the export products; after the unqualified products leave the dynamic belt scale 3, they are installed on the dynamic belt scale. After 3, the rejector 4 before the inkjet printer 5 rejects.

Method of the present invention is:

a. The barcode reader reads the barcode information of the cigarette box on the conveyor belt, and sends the information to the industrial computer;

b. The smoke box arrives at the dynamic belt scale, and the weight information is sent to the industrial computer after being weighed by the dynamic belt scale;

c. The industrial computer determines the specifications of the smoke box and the weight range of qualified products according to the barcode, and compares the weight information sent by the dynamic belt scale with the weight range of qualified products;

d. If the weight of the smoke box is within the weight range of qualified products, it will be sent to the inkjet printer after leaving the dynamic belt scale;

e. If the weight of the smoke box exceeds the weight range of qualified products, it will be removed by the rejector after leaving the dynamic belt scale;

f. According to the obtained barcode information, the industrial computer controls the inkjet printer to spray the corresponding content on the smoke boxes that need to be coded, and not to spray codes on the smoke boxes that do not need to be coded.
