Examples

As shown in the figures 1-4 of the drawings,

a code spraying detection device based on a linear array camera is used for detecting a code spraying of a cigarette packet 5 on a cigarette packet code spraying machine 1 and comprises a linear array camera 3 arranged at an outlet of the cigarette packet 5 on the cigarette packet code spraying machine 1, an LED light source 6 arranged at an outlet of the cigarette packet 5 on the cigarette packet code spraying machine 1 and a controller 2 arranged on the cigarette packet code spraying machine 1; the two LED light sources 6 are respectively arranged on two sides of the linear array camera 3; the light of the LED light source 6 faces to the cigarette packet 5 code spraying position on the cigarette packet code spraying machine 1. The controller 2 is respectively connected with the linear array camera 3 and the LED light source 6 through signals.

The cigarette packet removing device 4 is also included; the cigarette packet removing device 4 is installed at an outlet of a cigarette packet 5 on the cigarette packet code spraying machine 1, and the cigarette packet removing device 4 is arranged behind the linear array camera 3.

The cigarette packet removing device 4 comprises a cylinder bracket 40 arranged on the cigarette packet code spraying machine 1, a cylinder 41 with a cylinder body fixedly connected with the cylinder bracket 40 and a cigarette packet removing head 42 fixedly connected with a cylinder rod of the cylinder 41; the cigarette packet removing head 42 is rectangular, and the cigarette packet removing head 42 is matched with the removed cigarette packet 5.

The cylinder 41 is a double rod cylinder.

And a valve island is arranged on the cylinder 41 and is in signal connection with the controller 2. The valve island is a new generation of gas-electricity integrated control component, has been developed from the valve island with a multi-needle interface to the valve island with a field bus, and then a programmable valve island and a modular valve island appear. The valve island technology and the field bus technology are combined, so that the electric control valve is easy to wire, and debugging, performance detection, diagnosis and maintenance of a complex system are greatly simplified. By means of the information system with high-level integration of the field bus, the advantages of the field bus and the information system are fully exerted, and the method has wide application prospect.

The controller 2 is a PLC controller.

The system also comprises an industrial personal computer; the industrial personal computer is in signal connection with the controller 2; the linear array camera 3 transmits a photographing signal to the controller 2 and the industrial personal computer; the field operator can check the signal of the controller 2 through the industrial personal computer; and the line camera 3, the LED light source and the air cylinder 41 can be controlled by a controller 2.

The linear array camera 3 is an industrial camera with 6400/2100 ten thousand pixels in the Ginshi CV-X/XG-X series; industrial cameras are a key component in machine vision systems, and their most essential function is to convert light signals into ordered electrical signals. The selection of a proper camera is also an important link in the design of a machine vision system, and the selection of the camera not only directly determines the resolution, the image quality and the like of the acquired image, but also is directly related to the operation mode of the whole system;

differences between industrial cameras and ordinary cameras:

1. the industrial camera has stable and reliable performance, easy installation, compact and firm camera structure, long continuous working time and can be used in poor environment, which can not be realized by common digital cameras. For example: it is certainly impossible to operate a digital camera for civil use for 24 hours a day or for several days continuously.

2. The shutter time of an industrial camera is very short, and an object moving at a high speed can be captured. For example, a name card is stuck on the fan blade of an electric fan, the name card rotates at the maximum speed, the proper shutter time is set, an image is captured by an industrial camera, and the characters on the name card can still be clearly distinguished. The same effect cannot be achieved by using a common camera for capturing.

3. The image sensor of an industrial camera is progressive scanned, whereas the image sensor of a normal camera is interlaced scanned.

4. The frame rate of an industrial camera is much higher than that of a general camera. An industrial camera can take ten to hundreds of pictures per second, while a common camera can only take 2-3 images, which is quite different.

5. The industrial camera outputs raw data (raw data), and the spectral range of the raw data is often wide, so that the raw data is suitable for performing high-quality image processing algorithms, such as Machine Vision (Machine Vision) application. The spectrum range of the picture shot by the common camera is only suitable for the vision of human eyes, and the picture is compressed by mjpeg, so that the image quality is poor, and the picture is not beneficial to analysis and processing.

6. Industrial cameras (Industrial cameras) are relatively expensive compared to conventional cameras (DSCs).

The PLC controller adopted by the utility model is a Siemens programmable logic controller S7-200, and an operator can edit a program by himself after simple training and input the program into the PLC controller for working.

The working process of the utility model is as follows:

the device is installed on a cigarette packet code spraying machine 1, when the cigarette packet code spraying machine 1 sprays codes, a linear array camera 3 is started, an LED light source 6 is turned on to light a code spraying position of a cigarette packet 5 sprayed with the codes, the linear array camera 3 is convenient to take a picture, and when the cigarette packet 5 sprayed with the codes passes through the linear array camera 3; the linear array camera 3 shoots a code spraying position of the cigarette packet 5 and transmits a signal to the controller 2, and meanwhile, the linear array camera 3 transmits shot information to an industrial personal computer; after receiving the signal of the linear array camera 3, the controller 2 compares the signal with a standard code-spraying photo, and if the code-spraying of the cigarette packet 5 is incomplete; the controller 2 sends an instruction to the air cylinder 40, and the air cylinder 40 rejects the defective cigarette packet 5. The field operator can check the signal of the controller 2 through the industrial personal computer; and the linear array camera 3, the LED light source and the valve island of the air cylinder 41 can be controlled by the controller 2.

The above; but are merely preferred embodiments of the utility model; the scope of the utility model is not limited thereto; any person skilled in the art is within the technical scope of the present disclosure; the technical scheme and the improved concept of the utility model are equally replaced or changed; are intended to be covered by the scope of the present invention.
