Description

Technical Field

[0001] The present invention relates to the field of sorting equipment, and particularly to a defective tablet weighing and sorting equipment. Background Art

[0002] Tablet weighing and sorting technology is an automated technology used in pharmaceutical production and quality control. It can quickly and accurately detect the weight of tablets and automatically sort qualified and unqualified products according to the detection results. This technology is crucial for ensuring the uniformity and compliance of drug dosages. Especially in large-scale production processes, tablet weighing and sorting equipment generally includes the following key steps: Automatic conveying: Tablets enter the weighing area through a conveyor belt or a roller-type conveying system, and the conveying system can be adjusted according to the shape and size of the tablets to ensure stable weighing conditions; High-precision weighing: When the tablets reach the weighing area, high-precision weighing sensors quickly and accurately measure their weight. These sensors use digital signal processing technology to reduce external interference and ensure the accuracy and stability of the measurement results; Intelligent identification and sorting: After weighing, the intelligent identification system identifies the types and specifications of the tablets, and according to the preset sorting rules, the control system instructs the sorting mechanism to sort the tablets into corresponding channels or containers.

[0003] Chinese Patent CN110142207B discloses an intelligent tablet sorting device and sorting method, which mainly consists of four parts: a mass separation part, a tablet storage part, a volume separation part, a light sensing part, and a control part. First, the mass separation part includes a first box body with a medicine inlet, an air inlet fan inside the box body, an upper air outlet, and a lower medicine outlet. This part is mainly responsible for the preliminary separation of tablets. Secondly, the tablet storage part is located at the upper end of the first box body and is connected to the upper air outlet. It contains multiple vertically arranged and interconnected tablet storage units, and each unit has an adjustable air volume adjustment plate for further classification and storage of tablets. Then, the volume separation part includes a second box body connected to the lower medicine outlet, with multiple separable disks inside. These disks are arranged along the height direction of the box body for separating tablets according to their volume. Finally, the light sensing part is responsible for monitoring the position of the tablets, and the control part controls the opening and closing of the air volume adjustment plate and the separable disks according to the signals from the light sensing part, thereby realizing automatic sorting according to the mass and volume of the tablets.

[0004] The above patents and the prior art also have the following defects:

[0005] The tablet moves into the weighing area for weighing. During the weighing process, the tablet is in a moving state, and the weighing data of the tablet is inaccurate. Stopping the movement of the tablet will increase the weighing time of the tablet and reduce the production efficiency of the tablet. When the tablet is unqualified, the unqualified tablet needs to be sorted out by an action actuator. Since the tablet is in a moving state, the action time and accuracy of the action actuator are required to be relatively high, and sorting is more likely to go wrong.

[0006] Through the coordinated action of each part, this device can efficiently and accurately complete the classification and sorting of tablets, greatly improving the production efficiency and quality of medicines.

[0007] Therefore, this application provides a defective tablet weighing, selecting and sorting device to meet the requirements. Summary of the Invention

Specific implementation mode

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] Example 1: Refer to Figures 1 - 13 A tablet defective weighing and sorting device as shown, including a vibrating disk 1 and a sorting conveyor belt 2. A feeding assembly 6 is arranged between the vibrating disk 1 and the sorting conveyor belt 2. A plurality of sorting assemblies 3 are arranged on the sorting conveyor belt 2. A qualified conveyor belt 4 and a defective conveyor belt 5 are arranged at one end of the sorting conveyor belt 2 away from the vibrating disk 1;

[0043] The feeding assembly 6 includes a feeding tray 61 and a plurality of feeding chutes 62 equidistantly arranged on the feeding tray 61;

[0044] The sorting assembly 3 includes a weighing device 31 and a linear driver 32;

[0045] The feeding tray 61 can rotate. When the feeding chute 62 rotates to the position of the vibrating disk 1, the tablets on the vibrating disk 1 can enter the feeding chute 62. When the feeding chute 62 rotates to the position of the sorting conveyor belt 2, the tablets in the feeding chute 62 can fall onto the corresponding weighing device 31;

[0046] When the weighing result of the tablets by the weighing device 31 is unqualified, the linear driver 32 can push the weighing device 31 from the position of the qualified conveyor belt 4 to the position of the defective conveyor belt 5.

[0047] The vibrating disk 1 transports the tablets horizontally into the feeding chute 62 of the feeding tray 61. The feeding tray 61 rotates to drive the feeding chute 62 to rotate above the end of the sorting conveyor belt 2. When the feeding chute 62 rotates above the end of the sorting conveyor belt 2, the tablets in the feeding chute 62 fall onto the weighing device 31. The sorting conveyor belt 2 drives the weighing device 31 to move. During the movement, the weighing device 31 weighs the tablets. When the weight of the weighed tablets is qualified, the sorting conveyor belt 2 drives the weighing device 31 to move to the position of the qualified conveyor belt 4. As the sorting conveyor belt 2 moves, the tablets on the weighing device 31 fall onto the qualified conveyor belt 4 and are discharged through the qualified conveyor belt 4. When the weight of the weighed tablets is unqualified, the linear actuator 32 is started. The linear actuator 32 pushes the weighing device 31 to move, and moves the weighing device 31 to the position corresponding to the defective product conveyor belt 5. As the sorting conveyor belt 2 moves, the tablets on the weighing device 31 fall onto the defective product conveyor belt 5 and are transported out through the defective product conveyor belt 5.

[0048] The feeding chute 62 on the feeding tray 61 can only accommodate one tablet. By rotating the feeding tray 61, the feeding chute 62 feeds one tablet into the weighing device 31.

[0049] By rotating the feeding tray 61, the tablets in the feeding chute 62 fall onto the weighing device 31. The weighing device 31 weighs the tablets. When the tablets are damaged, the weighing result of the tablets is unqualified. The linear actuator 32 pushes the weighing device 31 to move, so that the weighing device 31 is pushed from the position corresponding to the qualified conveyor belt 4 to the position corresponding to the defective product conveyor belt 5, and the unqualified tablets on the weighing device 31 fall onto the defective product conveyor belt 5, sorting out the unqualified tablets with damage. During the process of weighing the tablets, the tablets move together with the weighing device 31, and the tablets and the weighing device 31 are relatively stationary. The weighing data of the tablets by the weighing device 31 is more accurate, and the weighing effect for small-weight items is better. The linear actuator 32 can push the weighing device 31 to move during the movement of the weighing device 31, and push the weighing device 31 and the unqualified tablets to the position of the defective product conveyor belt 5 for discharging. The time reserved for the linear actuator 32 to execute the action is long, the requirements for the action speed and action accuracy of the linear actuator 32 are low, and the sorting failure rate is reduced.

[0050] Example 2, refer to Figures 1 - 13, different from the above embodiments: The sorting component 3 further includes several group power supply units. The power supply unit includes a power supply base 33, a power supply rod 34, a power supply graphite 35, and a compression spring 36. The power supply rod 34 is rotatably connected to the power supply base 33 and electrically connected to the power supply base 33. The power supply graphite 35 is fixedly installed at the end of the power supply rod 34 and electrically connected to the power supply rod 34. A controller is installed on the sorting conveyor belt 2. The weighing device 31 and the linear driver 32 are both electrically connected to the power supply base 33. The power supply slip ring 7 is electrically connected to the controller. Power supply slip rings 7 are provided on both sides of the sorting conveyor belt 2 corresponding to the power supply units. One end of the compression spring 36 is fixedly installed on the power supply rod 34, and the compression spring 36 presses the power supply graphite 35 against the corresponding power supply slip ring 7 through the power supply rod 34.

[0051] Connect the controller to an external power source. During the movement of the weighing device 31 and the linear driver 32, the power supply base 33, the power supply rod 34, the power supply graphite 35, and the compression spring 36 move together. The compression spring 36 presses the power supply graphite 35 against the power supply slip ring 7. The weighing device 31 and the linear driver 32 are electrically connected to the controller through the power supply base 33, the power supply rod 34, the power supply graphite 35, and the power supply slip ring 7, so that the controller supplies power, transmits data, and issues commands to the weighing device 31 and the linear driver 32, ensuring normal power supply and data transmission of the weighing device 31 and the linear driver 32 moving on the sorting conveyor belt 2. At the same time, the power supply graphite 35 has the characteristics of high conductivity, low friction, and self-lubrication, reducing wear and improving the stability of electrical connection.

[0052] The power supply graphite 35 is of a detachable design. The power supply graphite 35, the controller, and the weighing device 31 are prior arts and will not be described in detail here.

[0053] The linear driver 32 is a cylinder in the prior art.

[0054] There are at least four groups of the power supply unit and the corresponding power supply slip rings 7. One group is used to connect the negative pole of the controller, one group is used to connect the positive pole of the controller, and the remaining two groups are used to transmit data.

[0055] Embodiment 3, referring to Figures 1 - 13 , different from the above embodiments: The sorting component 3 further includes a fixing strip 37, a fixing plate 38, and a fixing box 39. One side of the fixing strip 37 is fixedly installed on the sorting conveyor belt 2, and the other side of the fixing strip 37 is fixedly installed on the fixing plate 38. The fixing box 39 is slidably fitted on the fixing plate 38. The weighing device 31 is fixedly installed in the fixing box 39, and the top of the fixing box 39 is open.

[0056] The sorting conveyor belt 2 drives the fixed bar 37 to move, the fixed bar 37 drives the fixed plate 38 to move, the fixed plate 38 drives the fixed box 39 to move, the fixed box 39 drives the weighing device 31 to move. The weighing device 31 is installed in the fixed box 39. After the tablets fall onto the weighing device 31, it is not easy to fall off the weighing device 31. As the weighing device 31 moves to the end of the sorting conveyor belt 2, the opening of the fixed box 39 gradually rotates downward, and the tablets on the weighing device 31 in the fixed box 39 fall.

[0057] Example 4, refer to Figures 1 - 13 , which is different from the above embodiment in that: protective plates 8 are fixedly installed on both sides of the sorting conveyor belt 2, a protective shell 9 is fixedly installed on the side corresponding to the power supply slip ring 7, and a plurality of support frames 10 are fixedly installed in the protective shell 9. The power supply slip ring 7 is fixedly installed on the support frames 10.

[0058] The power supply slip ring 7 is fixedly installed in the protective plate 8 through the support frames 10 to ensure the stability of the power supply slip ring 7.

[0059] Example 5, refer to Figures 1 - 13 , which is different from the above embodiment in that: limiting wheels 11 are fixedly installed on both sides of the fixed plate 38, limiting grooves are formed in the protective plate 8 corresponding to the limiting wheels 11, the limiting wheels 11 are arranged in the corresponding limiting grooves, and two limiting blocks 12 are fixedly installed at one end of the fixed plate 38 away from the power supply slip ring 7. The two limiting blocks 12 are located on both sides of the limiting wheels 11.

[0060] The two limiting wheels 11 limit the fixed plate 38, and the fixed plate 38 will not move up and down. When the fixed plate 38 moves above the sorting conveyor belt 2, the limiting blocks 12 abut against the inner wall of the limiting groove, making the fixed plate 38 not easy to shake, thereby ensuring that the weighing device 31 is not easy to shake and ensuring the weighing accuracy of the weighing device 31. The thickness of the limiting blocks 12 is less than the width of the limiting groove, so that the limiting blocks 12 can tilt and move in the limiting groove when moving to the end of the sorting conveyor belt 2.

[0061] Example 6, refer to Figures 1 - 13 , which is different from the above embodiment in that: the linear actuator 32 is fixedly installed on the fixed plate 38, the output end of the linear actuator 32 is fixedly installed on the fixed box 39, the sorting assembly 3 further includes a T-shaped slider 13, the T-shaped slider 13 is fixedly installed on the fixed plate 38, and a T-shaped chute is formed at the bottom of the fixed box 39. The T-shaped slider 13 penetrates through the T-shaped chute and is slidably matched with the T-shaped chute.

[0062] The linear actuator 32 pushes the fixed box 39 to move. The fixed box 39 moves on the fixed plate 38 and the T-shaped slider 13. The T-shaped slider 13 limits the movement of the fixed box 39 without deviation, and the fixed box 39 is more stable.

[0063] Example 7, refer to Figures 1 - 13, which is different from the above embodiments in that: the feeding assembly 6 further includes a feeding table 63, a feeding motor 64, a limiting housing 65 and a feeding chute 66. The limiting housing 65 is fixedly installed on the feeding table 63, the feeding tray 61 is rotatably connected inside the limiting housing 65. The limiting housing 65 is provided with a blanking port at the position corresponding to the end of the sorting conveyor belt 2, and the limiting housing 65 is provided with a feeding port at the position corresponding to the feeding chute 66. One end of the feeding chute 66 is fixedly installed on the limiting housing 65, and the other end of the feeding chute 66 is fixedly connected to the output end of the vibrating disk 1. The feeding motor 64 is fixedly installed on the feeding table 63, and the output end of the feeding motor 64 is fixed on the feeding tray 61.

[0064] The vibrating disk 1 moves the tablets horizontally into the feeding chute 66, and the tablets are stored in the feeding chute 66. The feeding motor 64 drives the feeding tray 61 to rotate. When the feeding groove 62 on the feeding tray 61 rotates to the position of the feeding chute 66, the tablets in the feeding chute 66 move into the feeding groove 62. Since only one tablet can be accommodated in the feeding groove 62, the tablets in the feeding chute 66 enter the feeding groove 62 once with the rotation of the feeding tray 61. When the feeding groove 62 rotates to the end of the sorting conveyor belt 2, the tablets in the feeding groove 62 fall onto the weighing device 31 through the blanking port.

A plurality of transmission rollers 15 are rotatably connected to the protective plate 8, and the sorting conveyor belt 2 is arranged on the transmission rollers 15. A transmission motor 16 is fixedly installed on one of the protective plates 8, and the output end of the transmission motor 16 is fixedly installed on one of the transmission rollers 15.

[0066] The transmission motor 16 drives the transmission roller 15 to rotate, and the transmission roller 15 drives the sorting conveyor belt 2 to move.

[0067] Embodiment 9, referring to Figures 1 - 13 , which is different from the above embodiments in that: partition plates 17 are fixedly installed on both sides of the qualified conveyor belt 4 and the defective conveyor belt 5, and the partition plates 17 are fixedly installed on the transmission support 14.

[0068] The partition plates 17 separate the qualified conveyor belt 4 and the defective conveyor belt 5, making the falling position of the tablets more accurate and not easily offset.
