Description

Technical Field

[0001] This disclosure relates to the field of quality testing technology for traditional Chinese medicine decoction pieces, and in particular to a device and method for quality testing of traditional Chinese medicine decoction pieces. Background Technology

[0002] Traditional Chinese medicine (TCM) decoction pieces are "medicinal finished products" that have undergone processing of raw medicinal materials, possessing both "medicinal material properties" and "preparation properties." However, for a long time, quality issues with decoction pieces (such as adulteration of raw materials, non-standard processing, and substandard component content) have remained key bottlenecks restricting the clinical efficacy of TCM. The main problems are concentrated in incorrect raw materials (such as using "Daqingye" to impersonate "Banlangen" decoction pieces), uncontrolled processing techniques (such as excessive charring leading to loss of effective components), and excessive levels of harmful residues (such as heavy metals and pesticide residues).

[0003] Existing testing methods directly observe the appearance of the medicinal slices and measure moisture content, ash content (total ash and acid-insoluble ash), and extract content to assess the purity and stability of the slices. However, when testing medicinal slices, because the samples are not tested individually, the small size of the slices and their overlapping can affect the observation results. Furthermore, when using the water immersion method, impurities within the slices themselves can easily influence the test results. Summary of the Invention

[0015] A method for quality testing of traditional Chinese medicine decoction pieces, the method comprising the following steps:

[0016] (1) Place the Chinese herbal medicine pieces to be tested into the placement frame and move them to the bottom of the first detection component via the conveyor. Keep the second recognition camera of the first detection component and the placement frame on the same vertical line.

[0017] (2) The lifting component drives the first detection component to descend, and the first detection component unfolds the closed placement frame to expand the internal range of the placement frame and spread out the Chinese herbal medicine pieces. The second recognition camera detects the appearance of the Chinese herbal medicine pieces.

[0018] (3) After the placement frame is unfolded, the first detection component collects and cleans the debris and impurities that fall through the filter screen and sends them into the collection box on one side;

[0019] (4) After the first inspection is completed, the placement frame returns to the closed state and moves to the position of the lifting component as the conveyor continues to move. The lifting component and the placement frame are raised by the lifting component, and the placement frame is separated from the conveyor.

[0020] (5) After the placement frame is raised and tilted by the lifting component, the medicinal slices inside are poured into the soaking tank, and the situation inside the soaking tank is detected for the second time by the first recognition camera.

[0021] The technical solution provided in this disclosure may include the following beneficial effects:

[0022] 1. When the second recognition camera descends, the collection box will eventually stop at the bottom of the frame and on both sides of the opening of the bidirectional telescopic plate. The inclined block and the inclined surface cooperate to move the frame to both sides with the bottom plate as the center. During this process, the slide slides along the slide groove, the filter unfolds to block the bottom of the placement frame, expand the space of the placement frame, and facilitate the unfolding of the beverage pieces placed inside. During the movement of the frame, the push plate will move from the top of the stacked beverage pieces to simply spread out the beverage pieces that are stacked too high. The purpose of spreading them out here is to make it easier to directly detect their visual appearance compared to stacking them together. After the second recognition camera is reset, there is a spring inside the bidirectional telescopic plate, which uses elasticity to retract the size of the placement frame.

[0023] 2. In this invention, the leftmost bidirectional electric push rod of the moving plate drives the vertical plate and the insertion rod to move, inserting the insertion rod into the card holder cylinder furthest from the sweeping plate. Because the bottom of the card holder is engaged with the horizontal frame at this time, the sliding frame at the top of the card holder slides along the slide rail when the moving plate moves. Furthermore, the sweeping plate is magnetically attracted to the other end of the insertion rod, driving the sweeping plate to move. After the insertion rod moves out of the other set of collection boxes, through a squeezing action, the card slot at the bottom of the other set of card holders engages with the other end of the insertion rod. The right bidirectional electric push rod at the top of the moving plate drives the insertion rod to engage with the other set of card holders. The left bidirectional electric push rod separates the insertion rod from the original engagement. At this time, the moving plate continues... Continuing the movement, the insert is pulled out to the outside of another set of collection boxes. This process allows the insert to move inside the two collection boxes and moves the sweeping plate. After the sweeping plate enters the collection box, it can separate from the insert. The insert will not stay at the bottom of the placement frame. After one cleaning, the sweeping plate can be put back into one of the collection boxes without returning. When testing the medicine pieces inside the next set of placement frames, the sweeping plate can be directly returned to the original collection box through the insert. The cleaning of the bottom of the filter screen by the sweeping plate can prevent impurities and residues from entering the soaking tank when the medicine pieces inside the placement frame are poured out, which would affect the results of the second test.

[0024] 3. In this invention, the drive motor drives the gear to rotate, and the first toothed plate and the second toothed plate mesh with the gear and move in opposite directions along the outer wall of the conveyor table. The moving frame drives the first detection component to move vertically, moving closer to or away from the placement frame. The lifting component on the other side lifts the placement frame, which facilitates the simultaneous operation of the first detection station and the second detection station and improves detection efficiency.

[0025] 4. In this invention, when the first electric push rod retracts, the top plate and the support plate move along the moving notch. The support plate is attached to the surface of the conveyor belt, while the top plate is positioned at the top of both sides of the placement frame. The position of the support plate is not interfered with by the bottom plate. The placement frame stops at the position of the lifting component. The top plate contacts the top of the two surrounding frames, and the support plate contacts the bottom. Driven by the lifting component, the vertical frame slides along the guide plate, lifting the placement frame. The insert plate disengages from the slot of the bottom plate. After rising beyond the side plate of the conveyor table, it is pushed by the first electric push rod. The restriction of the placement frame by the top plate and the support plate, combined with the rotation of the top block and the connecting block, places the Chinese herbal medicine pieces inside the placement frame into the inside of the soaking tank. This facilitates the placement of the Chinese herbal medicine pieces to the next inspection station and the retraction of the placement frame to refill the Chinese herbal medicine pieces.

The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0047] like Figure 1 As shown, a method for quality testing of traditional Chinese medicine decoction pieces includes the following steps:

[0048] (1) Place the Chinese herbal medicine pieces to be tested into the placement frame and move them to the bottom of the first detection component via the conveyor. Keep the second recognition camera of the first detection component and the placement frame on the same vertical line.

[0049] (2) The lifting component drives the first detection component to descend, and the first detection component unfolds the closed placement frame to expand the internal range of the placement frame and spread out the Chinese herbal medicine pieces. The second recognition camera detects the appearance of the Chinese herbal medicine pieces.

[0050] (3) After the placement frame is unfolded, the first detection component collects and cleans the debris and impurities that fall through the filter screen and sends them into the collection box on one side;

[0051] (4) After the first inspection is completed, the placement frame returns to the closed state and moves to the position of the lifting component as the conveyor continues to move. The lifting component and the placement frame are raised by the lifting component, and the placement frame is separated from the conveyor.

[0052] (5) After the placement frame is raised and tilted by the lifting component, the medicinal slices inside are poured into the soaking tank, and the situation inside the soaking tank is detected for the second time by the first recognition camera.

[0053] like Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8As shown in the figure, this disclosure proposes a device for quality testing of traditional Chinese medicine decoction pieces, including: a conveyor table 1, with placement frames 2 equidistantly mounted on the belt surface of the conveyor table 1, a first detection component 3 located at the top center of the conveyor table 1, a lifting component 4 located at the tail end of the conveyor table 1, and a lifting component 6 located on the outer side of the conveyor table 1 between the lifting component 4 and the first detection component 3; a soaking tank 5 is fixed to one side of the outlet end of the conveyor table 1; the placement frames 2 include a base plate 21, which is fixed to the belt of the conveyor table 1, and A bidirectional telescopic plate 22 is placed on top of the base plate 21. A frame 23 is fixed to the two extended ends of the bidirectional telescopic plate 22, and side panels are slidably inserted into both sides of the two frames 23. The first detection component 3 includes a crossbeam 31, a second recognition camera 315 is fixed to the middle surface of the crossbeam 31, and collection boxes 310 are fixed to the bottom of both sides of the second recognition camera 315, with the collection boxes 310 sliding along the left and right sides of the placement frame 2. The lifting component 4 includes a vertical frame 41, with two sets of vertical frames 41 that slide together. Installed on the outer wall of the conveyor table 1, top blocks 42 are fixed on both sides of the top of the vertical frame 41 on the side of the conveyor table 1 away from the soaking tank 5, and top plates 44 are fixed to the top of the other side of the vertical frame 41, and the top plates 44 cover the top of the front and rear sides of the placement frame 2; the lifting assembly 6 includes gears 62, two of which are rotatably installed on both sides of the conveyor table 1 between the horizontal frame 31 and the vertical frame 41, and a shaft is fixed between the two gears 62. When using the device, the Chinese herbal medicine pieces to be tested are placed into the placement frame. Inside the frame 2, the medicine slices are moved to the bottom of the first detection component 3 by the conveyor 1. The lifting component 6 drives the first detection component 3 to descend. After the frame 2 is unfolded, the second recognition camera 315 inside the first detection component 3 inspects the appearance of the Chinese medicine slices and cleans the impurities and debris inside the frame 2. After the inspection is completed, the conveyor 1 moves the frame 2 to the position of the lifting component 4. The lifting component 4 raises the frame 2 and tilts it to pour the medicine slices inside into the soaking tank 5. The first recognition camera 32 then performs a second inspection on the inside of the soaking tank 5.

[0054] like Figure 2 and Figure 3 As shown, in some embodiments, the conveyor 1 has a moving notch 11 in the direction of movement of the first detection component 3 and the lifting component 4, the soaking tank 5 has a water inlet 51 on the top of the side away from the conveyor 1, and the soaking tank 5 has a slag discharge port 52 at the bottom of the water inlet 51; wherein, the cross frame 31 is fixed with a first identification camera 32 on one side of the soaking tank 5, and a turbidity detection device is installed on one side of the first identification camera 32.

[0055] It is understandable that clean water is added into the soaking tank 5 through the water inlet 51, and after soaking the Chinese herbal medicine slices, they are extracted from the slag outlet 52.

[0056] like Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, in some embodiments, the placement frame 2 further includes: a filter screen 26, a sliding plate 27, a sliding groove 28, and a return spring 29. A sliding groove 28 is provided on the outer side of the enclosure 23, and a sliding plate 27 is slidably connected inside the sliding groove 28. Filter screens 26 are slidably inserted into the bottoms of the two enclosures 23, and both ends of the filter screens 26 are fixedly connected to the sliding plate 27. A return spring 29 is fixedly fixed at an equal distance between the top of the sliding groove 28 and the sliding plate 27. A lever 210 is fixed inside the enclosure 23, and the bottom of the lever 210 is a certain distance from the filter screen 26. At certain intervals, the first detection component 3 further includes: an insertion interface 314, a rubber strip 319, and an inclined block 321. The collection box 310 has an insertion interface 314 at the position between the bottom of the frame 23 and the bidirectional telescopic plate 22. The frame 23 has vertical grooves 24 at both ends, and an inclined plate 25 is fixed inside the vertical grooves 24. An inclined block 321 is fixed at the top of both ends of the collection box 310, and the inclined block 321 slides along the inclined surface of the inclined plate 25. The top and bottom of the insertion interface 314 on the outside of the collection box 310 are fixed with rubber strips 319.

[0057] Understandably, when the second recognition camera 315 descends, the collection box 310 will eventually stop at the bottom of the frame 23 and on both sides of the opening of the bidirectional telescopic plate 22. The inclined block 321 cooperates with the inclined surface to move the frame 23 to both sides with the base plate 21 as the center. During this process, the slide plate 27 slides along the slide groove 28, and the filter screen 26 unfolds to block the bottom of the placement frame 2, expanding the space of the placement frame 2 and making it easier for the beverage pieces placed inside to unfold. During the movement of the frame 23, the lever 210 will move from the top of the stacked beverage pieces to simply spread out the beverage pieces that are stacked too high. The purpose of spreading them out here is to make it easier to directly detect their visual appearance compared to stacking them together. After the second recognition camera 315 is reset, the bidirectional telescopic plate 22 has a spring inside, which uses elasticity to retract the size of the placement frame 2.

[0058] like Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, in some embodiments, card holders 38 are provided on both sides of the second identification camera 315. A slide rail 311 is fixed between both ends of the cross frame 31 and the second identification camera 315. A sliding frame 312 is fixed to the top of the card holder 38, and the sliding frame 312 is slidably sleeved on the surface of the slide rail 311. A sweeping plate 320 is provided between the two collection boxes 310, and the sweeping plate 320 moves along the direction of the insertion interface 314. Insertion brackets 39 are slidably inserted into both ends of the sweeping plate 320. The bottom of the card holder 38 is provided with an elastic slot, and two sets of elastic slots of the card holder 38 are vertically inserted into both ends of the insertion bracket 39. A screw 33 is rotatably installed on one side of the cross frame 31, and a slide rod is fixed to the other end of the cross frame 31. A moving plate 3 is threaded onto the surface of the screw 33. 5. The other end of the movable plate 35 is slidably sleeved on the slide rod. The top two ends of the movable plate 35 are fixed with bidirectional electric push rods 34, and the extended end of the bidirectional electric push rods 34 is fixed with a vertical plate 36. The bottom of the vertical plate 36 is fixed with an insertion rod 37. The card holder 38 is fixed with insertion cylinders 313 on both sides corresponding to the insertion rods 37. The second recognition camera 315 is fixed with vacuum cleaners 316 on both sides perpendicular to the card holder 38. The two ends of the vacuum cleaners 316 are fixed with connecting pipes 317. The connecting pipes 317 are fixedly connected to the two ends of the collection box 310. The horizontal frame 31 is fixedly mounted with a motor at one end corresponding to the screw 33. The motor output end on the surface of the horizontal frame 31 is fixedly connected to the screw 33. The two ends of the horizontal frame 31 and the inside of the sweeping plate 320 are filled with magnetic material.

[0059] In this solution, the first identification camera 32 performs image recognition on the interior of the transparent soaking tank 5 and detects the breakage of the medicinal slices during soaking. It also uses a turbidity detection device to detect the turbidity inside the soaking tank 5. The second identification camera 315 inspects the appearance of the medicinal slices. The quality of the medicinal slices is determined through these two detection methods. The first and second identification cameras 32 and 315 are related to new material testing, metrology, standardization, and certification services. They utilize industrial vision, visual intelligence, AI vision, visual inspection, and visual measurement. The turbidity detection device employs a 90° scattering light method. It emits a beam of parallel light, commonly 860nm or 880nm infrared light to avoid color interference, which passes through the water sample. Suspended particles scatter the light. A photodetector is placed at a 90° angle to the incident light to receive the intensity of the scattered light.

[0060] It should be noted that the insert holder 39 and the sweeping plate 320 are slidably connected. The sweeping plate 320 moves between the two sets of collection boxes 310 as the insert holder 39 is pushed from both ends, passing between the frame 23 and the bidirectional telescopic plate 22 to clean up any fallen debris. For each detection of medicinal slices inside the placement frame 2, the sweeping plate 320 only moves from one set of collection boxes 310 to the other. Specifically, the moving plate 35 moves horizontally through a screw 33 driven by a motor, with the screw 33 threadedly engaging with the moving plate 35. Figure 7 As shown, when the sweeping plate 320 needs to be moved, the leftmost bidirectional electric push rod 34 of the moving plate 35 drives the vertical plate 36 and the insertion rod 37 to move, inserting the insertion rod 37 into the insert cylinder 313 of the bracket 38 furthest from the sweeping plate 320. Because the bottom of the bracket 38 is engaged with the horizontal frame 31 at this time, when the moving plate 35 moves, the sliding frame 312 at the top of the bracket 38 slides along the slide rail 311, and is driven to move by the magnetic attraction between the sweeping plate 320 and the other end of the bracket 39. After the bracket 39 moves out from the other set of collection boxes 310, the slot at the bottom of the other set of brackets 38 engages with the other end of the bracket 39 through the squeezing action. The right bidirectional electric push rod 34 at the top of the moving plate 35 drives the insertion rod 37 to engage with the other set of brackets. The left bidirectional electric push rod 34 separates the insertion rod 37 from the original engagement. At this time, the moving plate 35 continues to move. The insert 39 is pulled out to the outside of another set of collection boxes 310. This process allows the insert 39 to move inside the two collection boxes 310 and drives the sweeping plate 320 to move. After the sweeping plate 320 enters the collection box 310, it can separate from the insert 39. The insert 39 will not stay at the bottom of the placement frame 2. After one cleaning, the sweeping plate 320 can be put back into one of the collection boxes 310 without returning. When the next set of placement frames 2 is tested for medicinal slices, the sweeping plate 320 can be directly returned to the original collection box 310 through the insert 39. The sweeping plate 320 cleans the bottom of the filter screen 26, which can prevent impurities and residues from entering the soaking tank 5 when the medicinal slices are poured out of the placement frame 2, thus affecting the results of the second test. The impurities inside the collection box 310 are sucked out by the vacuum cleaner 316 and the connecting pipe 317.

[0061] like Figure 11As shown, in some embodiments, the lifting assembly 6 further includes: a first toothed plate 63, a second toothed plate 64, and a movable frame 65. The movable frame 65 is fixed at the bottom of both ends of the horizontal frame 31. A limit frame is fixed on the outer side of the conveying platform 1 corresponding to the position of the movable frame 65, and the movable frame 65 slides vertically along the limit frame. The gear 62 is meshed with the first toothed plate 63 on one side facing the movable frame 65, and the first toothed plate 63 is fixedly connected to the movable frame 65. The second toothed plate 64 is meshed with the other side of the gear 62, and the second toothed plate 64 is fixedly connected to the vertical frame 41. A drive motor 61 is fixed on the outer side of the conveying platform 1 corresponding to the position of the gear 62, and the output end of the drive motor 61 is fixedly connected to the gear 62.

[0062] It should be noted that the drive motor 61 drives the gear 62 to rotate, the first toothed plate 63 and the second toothed plate 64 mesh with the gear 62 and move in opposite directions along the outer wall of the conveyor table 1, the moving frame 65 drives the first detection component 3 to move vertically, closer to or away from the placement frame 2, and the lifting component 4 on the other side lifts the placement frame 2, so that the first detection station and the second detection station can be carried out at the same time, thus improving the detection efficiency.

[0063] like Figure 11 and Figure 12 As shown, the lifting assembly 4 further includes: a first electric push rod 43 and a support plate 45. The support plate 45 is fixed at the bottom of both sides of the placement frame 2, and the top of the base plate 21 has a slot. The bottom of the bidirectional telescopic plate 22 has an insert plate 211 fixed in the middle. The insert plate 211 is inserted into the slot of the base plate 21. The first electric push rod 43 is rotatably installed on the inner side of the vertical frame 41 on one side of the second gear 62, and the extended end of the first electric push rod 43 is fixedly connected to the top block 42. Guide plates 46 are fixed on both sides of the conveyor table 1 in the direction of movement of the vertical frame 41, and the vertical frame 41 is slidably engaged on the surface of the guide plate 46.

[0064] It should be noted that the top of both ends of the vertical frame 41 near the soaking tank 5 has a rotatable connecting block. The top plate 44 and the support plate 45 are connected via the connecting block and the top block 42. When the first electric push rod 43 retracts, the top plate 44 and the support plate 45 move along the moving notch 11. The support plate 45 rests on the surface of the conveyor belt, while the top plate 44 is positioned precisely at the top of both sides of the placement frame 2. The position of the support plate 45 is not interfered with by the bottom plate 21. The placement frame 2 remains in the position of the lifting assembly 4. The top plate 44 and the two surrounding frames 23... With the top contacting the bottom and the tray 45 in contact with the bottom, the vertical frame 41 slides along the guide plate 46 under the drive of the lifting assembly 6, raising the placement frame 2. The insert plate 211 disengages from the slot of the bottom plate 21 and rises beyond the side plate of the conveyor table 1. Then, it is pushed by the first electric push rod 43. The top plate 44 and the tray 45 restrict the placement frame 2. With the rotation of the top block 42 and the connecting block, the Chinese herbal medicine pieces inside the placement frame 2 are placed into the soaking tank 5. This makes it convenient to place the Chinese herbal medicine pieces to the next testing station and to recycle the placement frame 2 to refill the Chinese herbal medicine pieces.

[0065] Working principle:

[0066] When using the device, the Chinese herbal medicine pieces to be tested are placed inside the placement frame 2 and moved to the bottom of the first detection component 3 via the conveyor table 1. The drive motor 61 drives the gear 62 to rotate, and the first toothed plate 63 and the second toothed plate 64 mesh with the gear 62 and move in opposite directions along the outer wall of the conveyor table 1. The moving frame 65 drives the first detection component 3 to move vertically, closer to or away from the placement frame 2. The lifting component 4 on the other side lifts the placement frame 2, facilitating simultaneous operation of the first and second detection stations. After the placement frame 2 is unfolded, when the second identification camera 315 descends, the collection box 310 will eventually stop at the bottom of the enclosure 23 and on both sides of the opening of the bidirectional telescopic plate 22. The inclined block 321 cooperates with the inclined surface to move the enclosure 23 to both sides with the base plate 21 as the center. During the unfolding process, the slide plate 27 slides along the slide groove 28, and the filter screen 26 unfolds to block the bottom of the placement frame 2, expanding the space of the placement frame 2 and facilitating the unfolding of the beverage pieces placed inside. As the frame 23 moves, the paddle plate 210 moves from the top of the stacked beverage pieces, simply spreading out any excessively high stacks. Spreading them out makes them easier to visually inspect compared to stacking them together. After the second recognition camera 315 resets, the bidirectional telescopic plate 22 contains a spring that retracts the size of the placement frame 2 through elasticity. When the scanning plate 320 needs to be moved, the leftmost bidirectional electric push rod 34 of the moving plate 35 moves the vertical plate 36 and the insertion rod 37, inserting the insertion rod 37 into the holder 38 furthest from the scanning plate 320. Inside the cylinder 313, because the bottom of the card holder 38 is engaged with the crossbar 31, when the moving plate 35 moves, the sliding frame 312 at the top of the card holder 38 slides along the slide rail 311, and is magnetically attracted to the other end of the insert 39 by the sweeping plate 320, driving the sweeping plate 320 to move. After the insert 39 moves out of the other set of collection boxes 310, through the squeezing action, the card slot at the bottom of the other set of card holders 38 engages with the other end of the insert 39, causing the right bidirectional electric push rod 34 at the top of the moving plate 35 to drive the insert rod 37 to engage with the other set of card holders. The left bidirectional electric push rod 34 separates the insert rod 37 from the original engagement. At this time, the moving plate 35 continues to move, pulling part of the insert 39 out of the outside of the other set of collection boxes 310. This process can realize the insertion of the insert 39. The device moves within the two collection boxes 310, causing the sweeping plate 320 to move as well. After entering the collection box 310, the sweeping plate 320 can separate from the insert 39, which does not remain at the bottom of the placement frame 2. After one cleaning cycle, the sweeping plate 320 is retracted into one of the collection boxes 310 without needing to return. When testing the next set of medicinal slices in the placement frame 2, the sweeping plate 320 can be directly returned to the original collection box 310 via the insert 39. The sweeping plate 320 cleans the bottom of the filter screen 26, preventing impurities and residues from entering the soaking tank 5 when the medicinal slices are poured out of the placement frame 2, thus affecting the results of the second test. The vacuum cleaner 316 and connecting pipe 317 then suck out the impurities from inside the collection box 310.After the inspection is completed, the conveyor 1 moves the placement frame 2 to the position of the lifting component 4. The lifting component 4 raises the placement frame 2 and tilts it, pouring the medicinal slices inside into the soaking tank 5. The top of both ends of the vertical frame 41 near the soaking tank 5 has a rotating connecting block. The connecting block and the top block 42 connect the top plate 44 and the support plate 45. When the first electric push rod 43 retracts, the top plate 44 and the support plate 45 move along the moving notch 11. The support plate 45 is attached to the surface of the conveyor belt, while the top plate 44 is positioned at the top of both sides of the placement frame 2. The position of the support plate 45 is not interfered with by the bottom plate 21. The placement frame 2 remains at the position of the lifting component 4. Plate 44 contacts the top of the two surrounding frames 23, and support plate 45 contacts the bottom. Driven by the lifting assembly 6, the vertical frame 41 slides along the guide plate 46, lifting the placement frame 2. The insert plate 211 disengages from the slot of the bottom plate 21. After rising beyond the side plate of the conveyor table 1, it is pushed by the first electric push rod 43. The top plate 44 and support plate 45 restrict the placement frame 2. Combined with the rotation of the top block 42 and connecting block, the Chinese herbal medicine slices inside the placement frame 2 are placed into the soaking tank 5. This facilitates the placement of the Chinese herbal medicine slices to the next inspection station and the retraction of the placement frame 2 for refilling. The first recognition camera 32 performs a second inspection of the inside of the soaking tank 5.
