Description

Technical Field

[0001] This utility model relates to the technical field of grain counting machines, and in particular to a combined visual grain counting machine. Background Technology

[0002] Existing inline vision counting machines, as per the instruction manual Figure 1 and 2 As shown, the system includes a frame M1, a main vibrating plate M2 located at the top of the frame, multiple linear vibrating plates M3 longitudinally positioned to the left of the main vibrating plate and receiving their output materials, a storage hopper M4 located below the discharge end of each linear vibrating plate and receiving its output materials, a metering hopper M5 located below the storage hopper and receiving its output materials, a CCD vision system M7 located inside the frame with its lens facing the gap between the linear vibrating plates and the storage hopper and corresponding to the background light source M6, and a receiving hopper M8 located below the metering hopper and receiving the output materials from the multiple metering hoppers. The CCD vision system counts the materials entering each storage hopper. The quantity of material in the hopper is determined by the material being discharged from the storage hopper into the metering hopper. When the sum of the material quantities in several metering hoppers equals a set quantity, those metering hoppers discharge material simultaneously, causing it to fall into the receiving hopper and be output. Currently, a linear vision counting machine typically has about 6-10 metering hoppers on one side. To increase the probability of combination and improve weighing accuracy, the frame length needs to be increased to add more storage and metering hoppers. This would make the equipment longer, larger, and more expensive to manufacture. Therefore, there is an urgent need to design a combined vision counting machine to solve the above-mentioned problems.

[0031] The upper part of the main vibrating plate 2 has a roof-like structure, and the main vibrating plate 2 is installed in the middle of the top of the frame 1.

[0032] The linear vibratory feeders 3 are arranged in two rows, corresponding to the left and right sides of the main vibratory feeder 2 and fixed to the frame 1. The linear vibratory feeders 3 are used to receive the material output from the main vibratory feeder 2. Each row of linear vibratory feeders 3 has two, three, four, five or more. In this embodiment, it is preferred that each row has five linear vibratory feeders 3, and adjacent linear vibratory feeders 3 are overlapped. The linear vibratory feeder 3 has a wide-bottom structure, which means that the width of the vibratory feeder is wider than that of a conventional vibratory feeder, such as 5cm, 8cm or 10cm wider, etc.

[0033] The number of storage hoppers 4 is the same as the number of linear vibrating discs 3, and they are arranged one by one below the discharge end of the linear vibrating disc 3. That is, there are also two rows of storage hoppers 4. The storage hoppers 4 are connected to the frame 1. The storage hoppers 4 are used to receive the material output by the linear vibrating disc 3. The storage hoppers 4 are conventional double-door hoppers. The double doors at the bottom of the storage hoppers 4 are controlled to open and close by the drive device on them.

[0034] The number of metering hoppers 5 is the same as the number of storage hoppers 4, and they are arranged one-to-one below the storage hoppers 4. That is, there are also two rows of metering hoppers 5. The metering hoppers 5 are connected to the frame 1. The metering hoppers 5 are used to receive the materials output from the storage hoppers 4. The metering hoppers 5 are conventional double-door hoppers. The double doors at the bottom of the metering hoppers 5 are controlled to open and close by the drive device on them.

[0035] Two CCD vision systems 6 are provided and are located inside the frame 1. The lens end of one CCD vision system 6 faces the gap between the left linear vibrating plate 3 and the storage hopper 4 and corresponds to the first background light source 8. The lens end of the other CCD vision system 6 faces the gap between the right linear vibrating plate 3 and the storage hopper 4 and corresponds to the second background light source 9.

[0036] The receiving hopper 7 is located below the metering hopper 5. The upper end of the receiving hopper 7 is open, and the lower end has a discharge port. The receiving hopper 7 is used to receive all the materials output from the metering hopper 5.

[0037] The control device is an industrial computer, PLC controller, or microcontroller, etc. The control device is electrically connected to the main vibrating plate 2, the linear vibrating plate 3, the drive device for controlling the material feeding of the storage hopper 4, the drive device for controlling the material feeding of the metering hopper 5, and the CCD vision system 6. It is used to control the start and stop of each drive component. The first background light source 8 and the second background light source 9 are electrically connected to the control device. The control device controls the lighting and closing of the first background light source 8 and the second background light source 9.

[0038] CCD vision system 6 counting principle: When the material output from the linear vibrating plate 3 falls into the storage hopper 4, the material passes between the background light source (first background light source 8, second background light source 9) and the CCD vision system 6, leaving an image on the CCD vision system 6. The CCD vision system 6 can calculate the quantity of material by analyzing and calculating the image, and feed the quantity information back to the control device.

[0039] Each metering hopper 5 is equipped with a weighing sensor for weighing the material, and the weighing sensor is electrically connected to the control device.

[0040] The principle of the combined vision-based particle counting machine: When a set quantity of material needs to be output, after the equipment is started, the material is conveyed to the main vibrating plate 2 through the material conveying device. The material is then conveyed to both sides and output into each linear vibrating plate 3 by the vibration of the main vibrating plate 2. Each linear vibrating plate 3 starts and outputs the material by vibration into the storage hopper 4. During the process of the material falling into the storage hopper 4, the material passes between the background light source and the CCD vision system 6, leaving an image on the vision system. By analyzing and calculating the image, the CCD vision system 6 can calculate the number of materials entering each storage hopper 4. The system measures and feeds the quantity information back to the control device. After the linear vibratory feeder starts for a set time, the control device stops it and controls the drive device on the storage hopper 4 to open the two double doors at its lower end to discharge the material into the metering hopper 5. After the material is discharged, the double doors on the storage hopper 4 close. The control device records the quantity of material entering each metering hopper 5. When the sum of the quantities of material in several metering hoppers 5 equals the set quantity of material, the control device controls the drive device on those metering hoppers 5 to open the two double doors at its lower end to discharge the material into the receiving hopper 7 and output it. When materials need to be output according to the set weight, after the equipment is started, the material output by the main vibrating plate 2 enters each linear vibrating plate 3, and the material output by each linear vibrating plate 3 enters each storage hopper 4. The material is discharged from each storage hopper 4 into each metering hopper 5. The weight of the material in each metering hopper 5 is measured by the weighing sensor in each metering hopper 5, and the weight information is fed back to the control device. When the sum of the weights of the materials in several metering hoppers 5 equals the set material weight, the control device controls the drive device on those metering hoppers 5 to drive the two double doors at the bottom of them to open and discharge the material at the same time, so that the material falls into the receiving hopper 7 and is output. When material output is only possible under the dual conditions of meeting a set quantity and a set weight, after the equipment starts, the material output from the main vibrating plate 2 enters each linear vibrating plate 3, and the material output from each linear vibrating plate 3 enters each storage hopper 4. During the falling process of the material into the storage hopper 4, the CCD vision system 6 counts the quantity of material entering each storage hopper 4 and feeds the quantity information back to the control device. The material is discharged from each storage hopper 4 into each metering hopper 5. The weight of the material in each metering hopper 5 is measured by the weighing sensor in each metering hopper 5 and the weight information is fed back to the control device. When the sum of the quantity of material in several metering hoppers 5 equals the set quantity of material, and the sum of the weight of the material in several metering hoppers 5 equals the set weight of material, the control device controls the drive device on several metering hoppers 5 to drive the two double doors at the bottom of the hoppers to open and discharge the material into the receiving hopper 7 and output it.

[0041] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
