Description

Technical Field

[0001] This utility model belongs to the technical field of material counting equipment, specifically relating to a high-speed vision counting machine for counting multiple material combinations. Background Technology

[0002] In the production and packaging process of industries such as food, medicine, and hardware, it is often necessary to count and store various materials separately according to their respective target quantities in the same package. For example, in a mixed nut package, different types of nuts need to reach a specified number of pieces, and in a pharmaceutical package, different sizes of tablets need to be counted to the corresponding number of tablets.

[0003] Existing counting equipment typically uses a single-channel, single-material counting method. Each material requires a separate counting machine, and the machines operate independently. After counting, manual labor or additional auxiliary equipment is needed to combine multiple materials into the same package. This results in large equipment footprint, high costs, and cumbersome processes.

[0004] In existing particle counting equipment, when the material is close to the target quantity, the channel can be narrowed to a single-row passage through the flow limiting mechanism. However, during the transition phase of the flow limiting switch, multiple materials may still rush in at the same time, causing the count to exceed the limit. Once the count is exceeded, the existing equipment can only pour out all the materials in that batch and recount, resulting in the waste of materials that have been accurately counted and low efficiency in recounting. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-speed vision counting machine for multiple materials.

[0006] To achieve the above objectives, this utility model provides the following technical solution: it includes multiple feeding devices, multiple parallel material dropping channels, a vision device, and a storage box. The top of each material dropping channel is opposite to a different feeding device, and the bottom of each material dropping channel is connected to the storage box. Each material dropping channel is equipped with an upper baffle driven by a cylinder and a lower baffle driven by a cylinder. The upper baffle is located above the lower baffle. The vision device counts the materials entering the material dropping channel.

[0007] By adopting the above technical solution, during operation, multiple feeding devices convey different materials to their corresponding dropping channels. The upper baffle opens and the lower baffle closes, allowing the materials to fall onto the lower baffle for temporary storage. The vision device counts the materials entering the dropping channel. When the count reaches the target value, the upper baffle closes to cut off subsequent materials, and the lower baffle opens, allowing the temporarily stored materials to fall into the storage box. By using multiple parallel dropping channels corresponding to different feeding devices, multiple materials can be counted simultaneously and stored in a single storage box, avoiding the need for multiple devices to count separately and then merge, thus improving the efficiency of combined counting.

[0008] The present invention is further configured to include a discharge ramp, which is driven by a cylinder and has a discharge state and a standby state. In the discharge state, the top of the discharge ramp moves to below the lower baffle and is located between the material drop channel and the storage box; in the standby state, the discharge ramp moves away from the lower baffle.

[0009] By adopting the above technical solution, during operation, when the material quantity exceeds the target value, the discharge ramp is driven by a cylinder to move to the discharge state. Its top moves below the lower baffle and is located between the material drop channel and the collection box. The lower baffle opens, and the excess material falls onto the discharge ramp and is discharged along the ramp. When the material quantity is normal, the discharge ramp is in standby mode, away from the lower baffle, and does not interfere with normal material drop. By using the discharge ramp to discharge excess material separately when the quantity exceeds the target, only this type of material needs to be recounted, without the need to recount the entire batch, thus improving the error tolerance efficiency.

[0010] The present invention is further configured to include a recycling box, which is disposed at the bottom of the discharge ramp.

[0011] By adopting the above technical solution, the excess material discharged from the discharge ramp slides down the ramp and is collected in the recycling box. The recycling box collects the discharged excess material in a centralized manner, preventing the material from scattering and facilitating subsequent recounting and reuse.

[0012] The present invention is further configured such that: the feeding device includes an oscillator and an oscillation channel, the oscillator drives the oscillation channel and constitutes the forward movement of the material on the oscillation channel.

[0013] By adopting the above technical solution, during operation, the oscillator drives the oscillating channel to vibrate, and the material moves forward in an orderly manner along the oscillating channel under the action of vibration and is arranged into a single line to be conveyed to the material discharge channel; by driving the oscillator to oscillate the oscillating channel, the material is automatically arranged into a single line and moves forward in an orderly manner, ensuring that the material enters the material discharge channel one by one, and providing a stable single-line material supply for subsequent counting.

[0014] The present invention is further configured such that: a guide channel is provided between the oscillation channel and the material dropping channel, the guide channel is arranged at an angle, the guide channel is in contact with the oscillation channel, and there is a visual counting space between the guide channel and the material dropping channel.

[0015] By adopting the above technical solution, the material enters the guide channel from the oscillation channel and slides along the inclined surface of the guide channel to the discharge channel. The material is counted by the vision device when it passes through the visual counting space between the guide channel and the discharge channel. The inclined guide channel forms a natural transition between the oscillation channel and the discharge channel. At the same time, the visual counting space between the guide channel and the discharge channel makes the material present a regular passage state when it passes through, which makes it easy for the vision device to accurately capture and identify individual materials and reduce missed counts and miscounts.

[0016] The present invention is further configured such that the storage box is driven by a cylinder.

[0017] By adopting the above technical solution, after the materials in each feeding channel fall into the collection box, the cylinder drives the collection box to move for subsequent processing. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] like Figure 1-3As shown, this utility model discloses a high-speed vision counting machine for multiple materials, including multiple feeding devices 1, multiple parallel feeding channels 2, a vision device 5, and a storage box 6. The tops of the feeding channels 2 are respectively opposite to different feeding devices 1, and the bottoms of the multiple feeding channels 2 are all connected to the storage box 6. Each feeding channel 2 is provided with an upper baffle 21 driven by a cylinder and a lower baffle 22 driven by a cylinder. The upper baffle 21 is located above the lower baffle 22. The vision device 5 counts the materials entering the feeding channel 2. During operation, the multiple feeding devices 1 Different materials are conveyed to their respective feeding channels 2. The upper baffle 21 is opened and the lower baffle 22 is closed. The materials fall onto the lower baffle 22 for temporary storage. The vision device 5 counts the materials entering the feeding channel 2. When the count reaches the target value, the upper baffle 21 closes to cut off the subsequent materials, and the lower baffle 22 opens. The temporarily stored materials fall into the storage box 6. By using multiple parallel feeding channels 2 to correspond to different feeding devices 1, multiple materials can be counted and stored in one storage box 6 at the same time, avoiding the need for multiple devices to count separately and then merge them, thus improving the efficiency of combined counting.

[0023] The system includes a discharge ramp 3, which is driven by a cylinder and has a discharge state and a standby state. In the discharge state, the top of the discharge ramp 3 moves below the lower baffle 22 and is located between the material drop channel 2 and the storage box 6. In the standby state, the discharge ramp 3 is away from the lower baffle 22. During operation, when the material quantity exceeds the target value, the discharge ramp 3 is driven by the cylinder to move to the discharge state, with its top moving below the lower baffle 22 and located between the material drop channel 2 and the storage box 6. The lower baffle 22 opens, and the excess material falls onto the discharge ramp 3 and is discharged along the ramp. When the material quantity is normal, the discharge ramp 3 is in the standby state, away from the lower baffle 22, and does not interfere with normal material drop. The discharge ramp 3 discharges excess material separately when the quantity exceeds the target, requiring only the recounting of that type of material, rather than recounting the entire batch, thus improving error tolerance efficiency.

[0024] It also includes a recycling box 31, which is located at the bottom of the discharge ramp 3. During operation, excess material discharged from the discharge ramp 3 slides down the ramp and is collected in the recycling box 31. The recycling box 31 collects the discharged excess material in a concentrated manner to prevent the material from scattering and facilitates subsequent recounting and reuse.

[0025] The feeding device 1 includes an oscillator 11 and an oscillation channel 12. The oscillator 11 drives the oscillation channel 12 and causes the material to move forward on the oscillation channel 12. During operation, the oscillator 11 drives the oscillation channel 12 to vibrate. Under the action of vibration, the material moves forward in an orderly manner along the oscillation channel 12 and is arranged into a single column to be conveyed to the discharge channel 2. By driving the oscillation channel 12 with the oscillator 11, the material is automatically arranged into a single column and moves forward in an orderly manner, ensuring that the material enters the discharge channel 2 one by one, and providing a stable single column of material supply for subsequent counting.

[0026] A guide channel 4 is also provided between the oscillation channel 12 and the material discharge channel 2. The guide channel 4 is arranged at an angle and is in contact with the oscillation channel 12. There is a visual counting space between the guide channel 4 and the material discharge channel 2. During operation, the material enters the guide channel 4 from the oscillation channel 12 and slides along the inclined surface of the guide channel 4 to the material discharge channel 2. When the material passes through the visual counting space between the guide channel 4 and the material discharge channel 2, it is counted by the vision device 5. The inclined guide channel 4 forms a natural transition between the oscillation channel 12 and the material discharge channel 2. At the same time, the visual counting space between the guide channel 4 and the material discharge channel 2 makes the material present a regular passage state when it passes through, which makes it easy for the vision device 5 to accurately capture and identify individual materials and reduce missed counts and miscounts.

[0027] The storage box 6 is driven by a cylinder; during operation, after the materials from each feeding channel 2 fall into the storage box 6, the cylinder drives the storage box 6 to move for subsequent use.

[0028] It should be noted that Figure 2 Number 7 indicates the detection path of the vision device.

[0029] Working process: Different materials are placed into the corresponding oscillator 11 and oscillation channel 12. The oscillator 11 drives the oscillation channel 12 to vibrate, causing the materials to move forward in a single line. The materials enter the guide channel 4 from the oscillation channel 12 and slide along the inclined plane. When passing through the visual counting space between the guide channel 4 and the material drop channel 2, the visual device 5 counts the materials. At this time, the upper baffle 21 opens and the lower baffle 22 closes, and the materials fall onto the lower baffle 22 for temporary storage. When the count reaches the target value, the upper baffle 21 closes to cut off the subsequent materials. If the material quantity is normal, the lower baffle 22 opens and the materials fall into the collection box 6. If the material quantity exceeds the target value, the discharge ramp 3 moves to the discharge state, and the top of the discharge ramp 3 moves below the lower baffle 22. The lower baffle 22 opens, allowing the excess materials to fall onto the discharge ramp 3 and slide along the inclined plane into the recycling box 31. The qualified materials from each material drop channel 2 fall into the collection box 6. After one batch is completed, the cylinder drives the collection box 6 to move and switch to the receiving position for the next batch of materials.
