Detailed Description
For further understanding of the features and technical means of the present invention, as well as the specific objects and functions attained by the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.
As shown in fig. 2, 3, 6, and 7:
a plastic bottle recovery and sorting device based on visual inspection comprises a first conveyor belt 1, an air injection device 3 and an industrial camera 4,
the air injection device 3 comprises a plurality of air injection guns 3a, the air injection guns 3a are uniformly arranged on one side edge of the first conveyor belt 1, and the output directions of the air injection guns 3a face the first conveyor belt 1;
the industrial camera 4 is arranged above the first conveyor belt 1, the conveying direction of the first conveyor belt 1 is taken as the front, and the industrial camera 4 faces the surface of the first conveyor belt 1 behind the rearmost air gun 3 a;
and a guide member 6 is further included which,
the guide member 6 is composed of two vertical inclined plates 6a, the guide member 6 is disposed at the rear end of the first conveyor belt 1, the two vertical inclined plates 6a form a funnel shape, and the front of the funnel shape formed by the inclined plates 6a is narrower than the rear.
Based on the above embodiment, the device further comprises a controller, and the controller controls the whole operation of the device.
In this embodiment, there are three air lances 3a, from rear to front, corresponding to the transparent color, blue and green, respectively. The plastic bottles are most colorful in transparent color, blue and green are arranged, the three air guns 3a sort out the plastic bottles with the three colors, the plastic bottles with other colors flow out of the first conveyor belt 1, and then the plastic bottles with other colors are further sorted manually or in other modes. In actual production, according to the types and colors of plastic bottles required to be recycled and sorted, the number of the air guns 3a is not limited to three, the types of the sorted colors are also not limited to the three colors, and the air guns 3a are increased or decreased according to actual conditions.
When sorting the plastic bottles, the plastic bottles are poured onto the first conveyor 1 from the rear of the first conveyor 1, i.e. onto the first conveyor 1 from the input end of the first conveyor 1. After the plastic bottles are conveyed by the first conveyor belt 1, the industrial camera 4 firstly identifies the plastic bottles with different colors and transmits data to the controller, and the controller calculates the time required by the plastic bottles to reach the corresponding air guns 3a according to the colors of the plastic bottles through the rotating speed of the first conveyor belt 1. When the controller calculates that the plastic bottle with the color reaches the position of the corresponding air gun 3a, the air gun 3a at the position works to eject the plastic bottle with the corresponding color out of the first conveyor belt 1. Each time the air gun 3a is operated for a fixed time so that the air gun 3a stops blowing out the target plastic bottle. The fixed time of the air gun 3a can be adjusted manually by the controller.
An electromagnetic valve is installed in the air gun 3a, and the controller controls the air gun 3a to work by controlling the electromagnetic valve inside the air gun 3 a. When the air gun 3a works, the electromagnetic valve of the air gun 3a is controlled to be opened; the air gun 3a stops and the electromagnetic valve of the air gun 3a is controlled to close.
The purpose of the guide members 6 is to guide the orientation of the bottles so that their axes are all approximately parallel to the direction of conveyance of the first conveyor 1, i.e. to turn the bottles all vertically on the first conveyor 1. The front width of the funnel-shaped plastic bottle formed by the inclined plate 6a is slightly larger than the diameter of the plastic bottle, the funnel-shaped plastic bottle formed by the inclined plate 6a is guided by the inclined plate 6a, and finally the head or tail of the plastic bottle is drilled out from the narrower front of the inclined plate 6a, and the axis of the plastic bottle is approximately parallel to the conveying direction of the first conveyor belt 1. When the air gun 3a blows the plastic bottle later, the area of the plastic bottle facing the air gun 3a is larger, and the plastic bottle can be guaranteed to be blown out of the first conveyor belt 1 by the air gun 3 a.
Further, when the first conveyor belt 1 still has plastic bottles and conveys the plastic bottles on the first conveyor belt 1, the situation that the bottles are piled up easily occurs, which causes the defects that the guide member 6 is blocked, the industrial camera 4 is not easy to identify, and the air gun 3a is not easy to sort, in order to solve the problem, as shown in fig. 1:

Based on the above embodiment, the second conveyor belt 2 provided by the present application has a rotation speed less than that of the first conveyor belt 1, so that the plastic bottles on the second conveyor belt 2 individually fall onto the first conveyor belt 1, thereby solving the above problem. The output end of the second conveyor belt 2 is slightly higher than the input end of the first conveyor belt 1, so that the plastic bottles are prevented from being clamped at the joint of the second conveyor belt 2 and the first conveyor belt 1.
During actual sorting, plastics pour on second conveyer belt 2 earlier, through the conveying of second conveyer belt 2 again, because the speed of second conveyer belt 2 is less than the speed of first conveyer belt 1, when the plastic bottle on the second conveyer belt 2 falls into first conveyer belt 1 one by one, first conveyer belt 1 can be very fast convey away the plastic bottle to this increase plastic bottle's interval. Therefore, the plastic bottles piled on the second conveyor belt 2 are separated when falling onto the first conveyor belt 1 one by one, and the plastic bottles are prevented from being piled.
