[0035] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] Combine the following Figures 1 to 4 , the drop pill screening device and the drop pill production system provided by the embodiment of the utility model are described in detail through specific embodiments and their application scenarios.

[0037] First, as Figure 1 and Figure 4 As shown, this embodiment provides a pill screening device 1, including: a conveying component 11, used for conveying pills 3.

[0038] The imaging component 12 includes at least one imaging unit, and the imaging unit includes a laser emitter 121 and an imaging module 122. The laser emitter 121 and the imaging module 122 are arranged opposite to each other and are arranged on both sides of the conveying component 11; the laser emitter 121 is used to emit laser to the pill 3, and the imaging module 122 is used to collect the spot image formed by the laser passing through the pill 3.

[0039] The controller 13 is connected to the imaging unit and is used to determine the good quality status of the drop pill 3 according to the light spot image.

[0040] It can be understood that the pill 3 is composed of an inner core and an outer skin. When the laser is irradiated on the pill 3, the laser can penetrate the outer skin, but will be blocked by the inner core, thereby projecting through the pill 3 to form a spot image. The spot image includes an inner core area with grayscale and a transparent annular area. The inner core area is used to characterize the inner core of the pill 3, and the annular area is used to characterize the outer diameter of the pill 3.

[0041] The conveying component 11 is used to convey the pills 3 produced by the pill machine 2 to the imaging component 12 for laser irradiation to obtain the light spot formed by the pills 3 under laser irradiation. Specifically, the conveying component 11 can be a conveyor belt, a vibrating conveyor, or a screw conveyor.

[0042] Only one set of imaging units may be provided to acquire and collect the spot image of one drop pill 3, or multiple sets of imaging units may be provided to acquire and collect the spot images of multiple drop pills 3 simultaneously. The laser emitter 121 emits laser toward the drop pill 3, and the laser irradiates the drop pill 3 to form a spot image. For drop pills 3 of different qualities, such as those with unsatisfactory roundness, unsatisfactory outer diameter, eccentric inner core, hollow structure without inner core, or double core structure with two inner cores, they can be screened out by image analysis of the spot image.

[0043] The controller 13 of this embodiment controls the laser emitter 121 to emit laser toward the pill 3, and controls the imaging unit to collect the spot image; considering that the grayscale value of the inner core of the pill 3 in the spot image is much greater than the grayscale value of the outer skin of the pill 3 in the spot image, the controller 13 can adopt the image grayscale recognition technology known in the art, and determine the outer diameter of the pill 3 represented by the spot image, the concentricity of the inner core and the outer skin, the roundness of the outer skin, the number of the inner core, etc. by analyzing the grayscale value distribution of the spot image (such as the grayscale image), and then quickly detect and analyze the quality of the pill 3, so as to determine whether the detected pill 3 is a good product or a defective product.

[0044] Specifically, the controller 13 may be a PLC controller or a single chip microcomputer.

[0045] The pill screening device 1 provided by the utility model, by setting a transmission component 11, an imaging component 12 and a controller 13, can use the transmission component 11 to transport the pills 3 to the area where the imaging component 12 is located, use the laser emitter 121 to emit laser toward the pills 3, use the imaging module 122 to collect the spot image, use the controller 13 to analyze the spot image, determine the good state of the pills 3 according to the parameters of the spot image, and thus screen out qualified pills 3.

[0046] As can be seen from the above, the pill screening device 1 of the present invention can detect various unqualified states of the pills 3, and conveniently detect and screen the pills 3, thereby ensuring the quality of the pills 3.

[0047] In some embodiments, Figure 1 As shown, the conveying component 11 of this embodiment is provided with a plurality of storage positions 111 , and the plurality of storage positions 111 are sequentially arranged at intervals along the transmission direction of the conveying component 11 , and each storage position 111 is used to store one pill 3 .

[0048] The imaging assembly 12 includes a plurality of imaging units, which are arranged in sequence along the transmission direction of the transmission assembly 11 and can be arranged one by one opposite to the plurality of storage positions 111 .

[0049] It is understandable that the multiple storage positions 111 can store multiple pills 3 at the same time, and multiple sets of imaging units are arranged in a one-to-one correspondence with the multiple pills 3, so as to perform spot detection on the multiple pills 3 at the same time.

[0050] Specifically, the storage position 111 may be a groove, or a positioning box or a positioning screen.

[0051] In this embodiment, by providing multiple storage positions 111 and multiple sets of imaging units, and arranging the multiple imaging units and multiple storage positions 111 one by one, the pill screening device 1 can detect and screen multiple pills 3 at the same time, thereby improving the screening efficiency of the pills 3 and saving working time.

[0052] In some embodiments, Figure 1 As shown, the conveying assembly 11 of this embodiment includes: a conveying belt 112; a plurality of storage positions 111 are respectively arranged on the surface of the conveying belt 112 and are sequentially spaced along the extending direction of the conveying belt 112.

[0053] It is understandable that the conveyor belt 112 is easily integrated into the production line of the pills 3 to continuously transport the pills 3 so that the pills 3 produced by the pill machine 2 are continuously transported to the detection area. In addition, the conveyor belt 112 can also adjust the conveying speed according to the production efficiency of the pill machine 2 and the detection efficiency of the imaging unit to meet different needs. At the same time, the conveyor belt 112 automatically transports the pills 3, reducing the damage of the pills 3 during transportation and improving the efficiency and quality of transportation.

[0054] In some embodiments, Figure 1 and Figure 2 As shown, a baffle 113 is provided on one side of the storage position 111 of this embodiment; the conveyor belt 112 is arranged at an angle, and along the conveying direction of the conveyor belt 112 , the baffle 113 is arranged at the rear side of the storage position 111 .

[0055] It can be understood that the conveyor belt 112 is inclined and has a certain angle with the horizontal plane. After the pills 3 are sent out from the pill machine 2, they enter the conveyor belt 112. Under the action of gravity, the pills 3 slide toward the storage position 111 until they enter the storage position 111. A baffle 113 is provided on one side of the storage position 111 to stop the pills 3, so that the pills 3 are limited in the storage position 111.

[0056] In this embodiment, the conveyor belt 112 is set to be inclined, and a baffle 113 is provided on one side of the storage position 111, so that the pills 3 can enter the conveyor belt 112 from the pill machine 2 without human intervention. The pills 3 can automatically move to the storage position 111 and be located at the storage position 111, thereby improving the degree of automation and ensuring the reliability of the pills 3 being placed in the storage position 111 on the conveyor belt 112, thereby ensuring the reliability of spot image acquisition.

[0057] Furthermore, the blocking piece 113 can be configured to be arc-shaped, and the arc-shaped blocking piece 113 fits the outer wall of the drop pill 3 more closely, so that the positioning of the drop pill 3 is more stable.

[0058] Specifically, the baffle 113 can be set to be transparent. When the pills 3 are limited to the storage position 111, the transparent baffle 113 does not cover the pills 3, so that the staff can observe the shape of the pills 3 through the baffle 113.

[0059] In some embodiments, Figure 1 , Figure 3 and Figure 4 As shown, the pill screening device 1 of this embodiment further includes: a sorting component 14.

[0060] The sorting assembly 14 is disposed at the rear side of the conveying assembly 11 along the conveying direction of the conveying assembly 11 . The controller 13 is connected to the sorting assembly 14 to control the sorting state of the pills 3 by the sorting assembly 14 .

[0061] It is understandable that when the controller 13 has determined that the detected pills 3 are qualified or unqualified, the sorting component 14 is used to classify the qualified and unqualified pills 3 and separate the qualified and unqualified pills.

[0062] Specifically, the sorting component 14 can be a robotic arm, which can send qualified and unqualified pills 3 to different equipment for sorting and classification. The sorting component 14 can also be a pneumatic sorting system, which uses compressed air to process the unqualified pills 3 to the conveying component 11, thereby separating the qualified and unqualified pills 3.

[0063] In this embodiment, a sorting component 14 is provided and a controller 13 is used to control the sorting component 14 to separate qualified and unqualified pills 3 without manual intervention, thereby improving the automation of the pill screening device 1 and the screening efficiency.

[0064] In some embodiments, Figure 1 and Figure 4 As shown, the sorting component 14 of this embodiment includes a first sorting slot 141 , a second sorting slot 142 and a sorting actuator 143 .

[0065] The controller 13 is connected to the sorting actuator 143 to control the sorting actuator 143 to switch between the first state and the second state.

[0066] When the sorting execution element 143 is in the first state, the sorting execution element 143 is used to transfer the pellets 3 determined as good products by the controller 13 to the first sorting tank 141 .

[0067] When the sorting execution element 143 is in the second state, the sorting execution element 143 is used to transfer the pills 3 determined as defective by the controller 13 to the second sorting tank 142 .

[0068] It is understandable that the first sorting slot 141 is used to accommodate qualified pills 3, the second sorting slot 142 is used to accommodate unqualified pills 3, and the sorting actuator 143 is used to switch the state between the first sorting slot 141 and the second sorting slot 142 to separate qualified pills 3 from unqualified pills 3, so that qualified pills 3 are sent to the first sorting slot 141, and unqualified pills 3 are sent to the second sorting slot 142. The first sorting slot 141 and the second sorting slot 142 can be arranged in parallel or at an angle, and it is only necessary to ensure that the sorting actuator 143 can switch the state in the first sorting slot 141 and the second sorting slot 142.

[0069] Specifically, the sorting actuator 143 may be a baffle or a push rod.

[0070] When the sorting actuator 143 is a baffle, the baffle can be rotatably arranged between the first sorting slot 141 and the second sorting slot 142. When the sorting actuator 143 is in the first state, the baffle is rotated to the second sorting slot 142 to block the second sorting slot 142, so that the pills 3 can only be delivered to the first sorting slot 141; when the sorting actuator 143 is in the second state, the baffle is rotated to the first sorting slot 141 to block the first sorting slot 141, so that the pills 3 can only be delivered to the second sorting slot 142.

[0071] When the sorting actuator 143 is a push rod, the push rod is retractably arranged between the first sorting slot 141 and the second sorting slot 142. When the sorting actuator 143 is in the first state, the push rod pushes the pill 3 into the first sorting slot 141. When the sorting actuator 143 is in the second state, the push rod pushes the pill 3 into the second sorting slot 142.

[0072] In this embodiment, by providing a first sorting slot 141, a second sorting slot 142 and a sorting actuator 143, qualified pills 3 are sent to the first sorting slot 141 and unqualified pills 3 are sent to the second sorting slot 142 through the state switching of the sorting actuator 143, so that good and unqualified pills 3 can be automatically separated, and the staff can obtain good and unqualified pills respectively, thereby improving the efficiency of screening.

[0073] In some embodiments, Figure 3 and Figure 4 As shown, the sorting component 14 of this embodiment includes a blowing component 144; the blowing component 144 is used to blow the droplets 3 determined as unqualified by the controller 13 to the recovery station.

[0074] It is understandable that when the staff only needs to obtain qualified pills 3 and recycle unqualified pills 3, the blowing component 144 can blow the unqualified pills 3 away from the conveying component 11 and blow them to the recycling station, so that the qualified pills 3 are still located in the storage position 111, which is convenient for the next step of operation on the qualified pills 3.

[0075] In some embodiments, Figure 3 and Figure 4 As shown, the blowing assembly 144 of this embodiment includes: a nozzle 1441 and a detection element 1442.

[0076] The detection element 1442 is connected to the controller 13, and the controller 13 is connected to the nozzle 1441. The detection element 1442 is used to detect the position information of the pill 3, and the controller 13 is used to control the nozzle 1441 to blow air toward the pill 3 determined to be defective when the position information of the pill 3 matches the blowing position of the nozzle 1441.

[0077] It is understandable that since the position of the imaging unit relative to the conveying component 11 is fixed, when multiple pills 3 are conveyed simultaneously on the conveying component 11, the controller 13 can determine the good and bad pills among the multiple pills 3, and use the detection component to detect the position information of each pill 3. According to the moving speed of the conveying component 11 and the position information of each pill 3, the controller 13 can convert the moving time of each pill 3 to the blowing position, and then when a certain pill 3 is a bad pill and the pill 3 moves to the blowing position, the controller 13 controls the nozzle 1441 to blow air toward the bad pill 3 to blow the bad pill 3 out of the conveying component 11, so that only good pills remain on the conveying component 11.

[0078] Specifically, the detection element 1442 may be an angle sensor.

[0079] In this embodiment, a nozzle 1441 and a detection element 1442 are provided so that the position of unqualified pills 3 is detected by using the detection element 1442, thereby obtaining the movement time of the unqualified pills 3 to the spraying position. When the unqualified pills move to the spraying position, the controller 13 controls the spray head to blow air toward the unqualified pills 3, thereby realizing automatic screening of the unqualified pills 3.

[0080] In some embodiments, Figure 1As shown, the pill screening device 1 of this embodiment also includes: a primary screening component 15, which is configured to be arranged between the pill machine 2 and the conveying component 11, and the primary screening component 15 screens out the pills 3 with a particle size within a preset range, and transports the screened pills 3 to the conveying component 11.

[0081] It is understandable that the primary screening component 15 is used to perform preliminary screening on the outer diameters of the pills 3 , screen out the pills 3 with too small or too large outer diameters within a certain particle size atmosphere, and transport the pills 3 with appropriate particle size ranges to the conveying component 11 .

[0082] Specifically, the present embodiment may adopt a three-layer screening component, wherein the screening components are arranged at intervals from top to bottom, the top screening component uses a large particle size screen, the middle screening component uses a suitable screen, and the bottom screening component uses a small particle size screen. The pills 3 of the pill machine 2 are fed into the top screening component, and the pills 3 with too large a particle size are retained in the top screening component. The remaining pills 3 pass through the top screen and fall into the middle screening component, and the pills 3 with too small a particle size pass through the middle screen and fall into the bottom screening component. The pills 3 with a particle size that meets a certain range are retained in the middle screen. The middle screen is connected to the conveying component 11 to transport the screened pills 3 to the conveying component 11.

[0083] By providing the primary screening component 15, the present embodiment can perform preliminary screening before detecting and sorting the pills 3, and screen out the pills 3 whose outer diameters do not meet the requirements and the pills 3 that are stuck together, thereby reducing the number of pills 3 sent to the imaging component 12 area through the conveying component 11, reducing the workload of the imaging component 12, and thus improving the efficiency of screening qualified pills 3.

[0084] In a second aspect, in some embodiments, as Figure 1 As shown, this embodiment provides a pill production system, including: a pill machine 2 and a pill screening device 1; the pill machine 2 is used to supply the pills 3 to be screened to the conveying component 11.

[0085] Specifically, since the pill production system includes a pill screening device 1, and the specific structure of the pill screening device 1 refers to the above embodiment, the pill production system shown in this embodiment includes all the technical solutions of the above embodiment, and therefore, at least has all the beneficial effects achieved by all the technical solutions of the above embodiment, which will not be repeated here one by one.

[0086] It is understandable that the pills 3 produced by the pill machine 2 are sent to the pill screening device 1 to screen the pills 3 into good and unqualified products, and provide qualified pills 3 for the next workstation.

[0087] Furthermore, the spot images of unqualified pills 3 collected by the pill screening device 1 can be classified and analyzed, and the spot images of the pills 3 whose roundness does not meet the requirements, whose outer diameter does not meet the requirements, and whose inner core is eccentric can be further analyzed. The angle of roundness deviation, the position of the outer diameter that is too large or too small, and the position of the eccentric inner core can be statistically calculated, and the feedback can be given to the pill machine 2 through the controller 13 to adjust the preparation parameters of the pill machine 2 so as to reduce the number of unqualified pills 3, thereby improving the production quality of the pill production system and ensuring the consistency of the pill production.

[0088] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
