Detailed Description
The core of the utility model is to provide a stockpile detection system, which is not affected by the shape of stockpiles, and reduces the probability of missed detection; the defective rubber material can be detected, and the waste tire rate is reduced; and the detection is timely without delay.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a stockpile detection system according to the present invention.
The system comprises:
a camera 21 for taking a picture of the rubber material on the conveyor belt in real time to obtain a picture;
the image processor 22 is connected with the image acquisition device and is used for comparing the shape of the rubber material between the picture and the normal rubber material picture so as to judge whether the rubber material is abnormal or not, and if so, the alarm device 23 is controlled to give an alarm;
and an alarm device 23 connected to the image processor 22.
The stockpile detection system comprises a camera 21, an image processor 22 and an alarm device 23, wherein the image acquisition device photographs rubber materials on the conveyor belt to obtain a picture comprising the rubber materials, and the shape of the rubber materials can be reflected in the picture. Taking the camera 21 disposed at the side of the conveyor belt as an example, the shape of the side of the rubber material is not clear, and the shape of the side of the rubber material can be shown in the picture regardless of whether the rubber material is curled, protruded or sunk into the gap. Taking the example that the camera 21 is disposed above the conveyor belt, when the glue curls, protrudes or falls into the gap, the glue will show a color change or a folding line (different from two sides of the glue and formed when the glue curls, protrudes or falls into the gap) on the picture, and the shape above the glue (opposite to the side) can also be shown by the color change and/or the folding line.
After obtaining the picture, the image processor 22 may perform a glue shape comparison between the picture and a normal glue picture. Specifically, if the rubber is shot from the side of the conveyor belt, the height of the rubber in the normal rubber picture is fixed, and the uneven condition cannot occur. If the rubber material is normal, the height of the rubber material in the picture is the same as that of the normal rubber material picture, if the rubber material is curled, protruded or sunken, the height of the rubber material is uneven and is different from that of the normal rubber material picture, on the basis, the shape of the rubber material is compared (the height can be specifically compared) between the picture and the normal rubber material picture, if the rubber material is the same, the rubber material is normal, if the rubber material is different, the rubber material is abnormal, and at the moment, the alarm device 23 is controlled to give an alarm.
If the rubber material is shot from the upper part of the conveying belt, the color of the rubber material in the normal rubber material picture is the same and no broken line appears. At this time, if the glue is normal, the glue is the same as a normal glue picture (the color of the glue in the normal glue picture does not change and has no folding line), otherwise, the color of the glue in the picture is different from that in the normal glue picture and has a folding line. Based on this, the shape of the sizing material is compared with that of a normal sizing material picture (specifically, the shape can be compared through the color and the folding line), if the shape is the same, the sizing material is normal, if the shape is not the same, the sizing material is abnormal, and at this time, the alarm device 23 is controlled to give an alarm. Of course, the specific installation position of the camera 21 in the present application is not particularly limited, and the object of the present application can be achieved.
After the alarm device 23 gives an alarm, the worker can know that the sizing material has a problem in time, and subsequent operations such as shutdown processing are convenient to perform.
Therefore, the detection mode based on the pictures provided by the application can determine that the sizing material is abnormal as long as the shape of the sizing material in the pictures is different from that of the sizing material in the normal sizing material pictures, is not influenced by the shape of the piled materials, and reduces the probability of missed detection; the defective rubber material can be detected, and the waste tire rate is reduced; and the detection is timely without delay.
Referring to fig. 3, fig. 3 is a schematic structural diagram of another windrow detection system provided by the present invention.
On the basis of the above-described embodiment:
as a preferred embodiment, further comprising:
a control device 25 connected to the image processor 22;
the image processor 22 is also used for reporting abnormal information after judging that the sizing material is abnormal;
the control device 25 is used to control the conveyor belt to stop operating when the abnormality information is received.
Specifically, after the rubber material is abnormal, the image processor immediately reports abnormal information to the control device 25, and the control device 25 immediately controls the conveyor belt to stop working after receiving the abnormal information, so that the worker can timely process the abnormal rubber material, and the abnormal rubber material is prevented from performing subsequent processes. Furthermore, the image processor 22 may also stop processing the pictures sent back by the camera 21 after determining that the gum material is abnormal, so as to avoid reporting the abnormal information to the control device 25 until the control device 25 controls the conveyor belt to work again (in this case, it is usually stated that the abnormal condition has been processed).
The control device 25 may be, but is not limited to, a PCL (Programmable Controller) control cabinet, and the present application is not limited thereto.
As a preferred embodiment, the cameras 21 are plural and arranged in series along the conveyor belt.
In order to improve the detection efficiency, the plurality of cameras 21 may be sequentially arranged along the direction of conveying the rubber material by the conveyor belt, so that the image processor 22 may perform abnormality determination on the photos taken by the plurality of cameras 21 at the same time (the processing speed of the processor is very fast, and is usually much higher than the photographing speed of the cameras 21, so that it can be understood that the detection efficiency is high. Of course, the number of the cameras 21 to be selected is not particularly limited in the present application, and is determined according to actual situations.
As a preferred embodiment, further comprising:
a switch 24 connected to the plurality of cameras 21, the image processor 22, and the control device 25, respectively, for communication between the cameras 21 and the image processor 22 and between the image processor 22 and the control device 25.
When there are a plurality of cameras 21, considering that there are not so many communication interfaces in some image processors 22, and it is not possible to directly connect with a plurality of cameras 21 and the control device 25 at the same time, in this embodiment, a switch 24 is further provided, and the image processor 22 communicates with a plurality of cameras 21 through the switch 24, and the image processor 22 also communicates with the control device 25 through the switch 24, and this arrangement is suitable for image processors 22 without too many communication interfaces, and reduces the occupation of space of the image processor 22 by the communication interfaces.
As a preferred embodiment, the camera 21 is disposed at a side of the conveyor belt;
specifically, if the rubber is shot from the side of the conveyor belt, the height of the rubber in the normal rubber picture is fixed, and the uneven condition cannot occur. If the rubber material is normal, the height of the rubber material in the picture is the same as that of the normal rubber material picture, if the rubber material is curled, protruded or sunken, the height of the rubber material is uneven and is different from that of the normal rubber material picture, on the basis, the picture and the normal rubber material picture are compared in the height of the rubber material to judge whether the rubber material is abnormal or not, if the rubber material is the same, the rubber material is normal, if the rubber material is not the same, the rubber material is abnormal, and at the moment, the alarm device 23 is controlled to give an alarm.
The camera 21 can be arranged on the side of the conveyor belt, so that the shape of the side edge of the rubber material on the conveyor belt can be obtained visually, whether the rubber material is abnormal or not can be judged easily through the shape of the rubber material, and the detection accuracy is improved.
As a preferred embodiment, the camera 21 is a two-dimensional camera or a three-dimensional camera.
Specifically, the camera 21 may be a two-dimensional camera or a three-dimensional camera. The two-dimensional camera has the advantage of low cost, and the three-dimensional camera has the advantage of more accurate shape of the obtained sizing material. When the two-dimensional camera is selected, the two-dimensional camera is preferably arranged on the side of the conveying belt, and when the three-dimensional camera is selected, the shape of the clear sizing material can be obtained at other positions as long as the two-dimensional camera is not arranged below the conveying belt, so that the application range of the position is more flexible. The specific camera to be selected is not particularly limited, and is determined according to the actual situation.
As a preferred embodiment, the alarm means 23 comprise acoustic alarm means and/or luminous alarm means.
Specifically, the sound alarm device emits sound alarm, and the light alarm device emits light alarm, where the sound alarm device may be but is not limited to a buzzer, and the light alarm device may be but is not limited to a flashlight.
As a preferred embodiment, further comprising:
a storage device connected to the image processor 22;
the image processor 22 is also used to save the pictures to a storage device.
Specifically, it is considered that the detection method in the prior art cannot reduce the occurrence process of the windrow, that is, cannot directly determine whether the rubber material is accumulated due to the viscosity of the rubber material or the structural problem of the tire building machine, so that the cause of the windrow cannot be quickly determined.
In this embodiment, the image processor 22 stores the picture in the storage device after receiving the picture, so that a subsequent user can quickly determine the reason causing stacking in a mode of calling the picture, thereby eliminating hidden troubles in time and reducing the shutdown time of the device.
As a preferred embodiment, further comprising:
a display device connected to the image processor 22;
the image processor 22 is also used for comparing the pictures with the abnormal sizing material pictures to determine the specific abnormal type of the sizing material after judging that the sizing material is abnormal, and displaying the specific abnormal type on the display device.
In order to further facilitate the user to determine the specific abnormal type in time, in the scheme provided in this embodiment, the rubber material may be photographed in advance under various abnormal conditions, the obtained picture is taken as an abnormal rubber material picture, when the subsequent image processor 22 determines that the rubber material is abnormal, the picture is compared with the abnormal rubber material picture to determine the abnormal rubber material picture which is the same as the picture, the abnormal type corresponding to the abnormal rubber material picture is taken as the specific abnormal type corresponding to the rubber material, and the specific abnormal type is displayed on the display device, so that the worker can directly obtain the specific abnormal type of the rubber material, thereby further facilitating subsequent hidden danger elimination and reducing the shutdown time of the equipment.
As a preferred embodiment, the display device is an upper computer.
Specifically, the tire building machine is usually equipped with an upper computer directly interacting with a user, and in the embodiment, the upper computer can also display specific abnormal types, so that an additional display device is not needed, and the cost is reduced.
