[0067] Exemplary embodiments of this application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are for teaching those skilled in the art how to implement this application only, and are not intended to exhaust all possible methods of this application, nor to limit the scope of this application.
[0068] In this application, unless otherwise specified, "raw material package" includes both the raw material and the packaging containing the raw material. "Raw material" can be any possible powder, such as a chemical reagent, pharmaceutical, seasoning, or food additive. The raw material here includes at least fine powders and granules.
[0069] Figure 1 This is a schematic diagram of a mixing device according to an embodiment of this application.
[0070] The mixing device 30 may include a receiver 48 and a cutter 50. At the cutting station 46, the receiver 48 may receive different raw material packages 34, and the cutter 50 may construct openings on the received raw material packages 34 for discharging the raw materials. Different raw material packages 34 may contain different raw materials. Here, "different raw materials" can refer to either different types of raw material components or different proportions of raw material components.
[0071] like Figure 5 As shown, the mixing device 30 may also include a detector 52. The detector 52 may include a barcode scanner and a camera. At the cutting station 46, the scanner can scan the barcode or QR code on the raw material package 34 to help identify the raw materials inside the raw material package 34; the camera can photograph the raw material package 34 to capture the position and orientation of the raw material package.
[0072] The mixing device 30 may further include a selector 54 and a plurality of collectors 56. The selector 54 may include a second driver and a disc-shaped conveying element 58. The conveying element 58 may be disposed below the receiver 48, and its central axis may be parallel to the vertical direction. The second driver may be connected to the conveying element 58 and capable of driving the conveying element 58 to rotate about its central axis. For example, the second driver may be a motor. The collectors 56 may be detachably mounted on the conveying element 58, and a plurality of collectors 56 may be arranged side-by-side in the circumference of the conveying element 58. For example, the disc-shaped conveying element 58 may have a plurality of holes along its circumference, and the collectors may be installed in the corresponding holes. Furthermore, the mounting holes may have limiting members to restrict the movement of the collectors along the depth direction of the holes.
[0073] The conveying element 58 provided in this application can switch different collectors 56 to the collection station 62, so that different raw materials will not contaminate each other.
[0074] The mixing device 30 may also include a waste container 60. The waste container 60 may be fixedly mounted on the conveying element 58 and arranged side by side with the collector 56 in the circumferential direction of the conveying element 58. After the raw materials in the raw material package 34 are poured out, the waste container 60 can collect the packaging of the raw material package 34.
[0075] In other embodiments, the waste box 60 may not move with the conveying element 58.
[0076] Figure 2 This is a top view of the mixing device.
[0077] The receiver 48 can convey a raw material package 34 with an opening from the cutting station 46 to the collection station 62. At the collection station 62, one of a plurality of collectors 56 can be positioned directly below the raw material package 34. The receiver 48 can flip the raw material package 34, thereby emptying the raw material from the package 34 into the collector 56. For different raw materials, the conveying element 58 can pre-select different collectors 56 to the collection station 62 by its own rotation.
[0078] The cutting station 46 and the collection station 62 can be arranged side-by-side circumferentially on the conveying element 58 and opposite to each other radially on the conveying element 58. The conveying element 58 can transport the waste container 60 to the cutting station 46 by its own rotation. Alternatively, the waste container 60 can remain at the cutting station 46. In this way, packaging fragments falling from the raw material package 34 can be collected by the waste container 60 during the process of the shearer 50 creating the opening.
[0079] In other embodiments, the raw material package 34 may not generate packaging fragments during the process of constructing the opening. In this case, the waste container 60 does not need to be conveyed to the cutting station 46.
[0080] The mixing device 30 may also include a cleaner (not shown). The cleaner may be located at a cleaning station 64 and removes residual material from the collector 56 by generating positive pressure to purge it. For example, the cleaner may be configured as a fan, and the airflow from the cleaner may blow the material away from the collector 56. The collecting station 62 and the cleaning station 64 may be arranged side-by-side and adjacent to each other in the circumferential direction of the conveying element 58. The conveying element 58 may, by its own rotation, transport the collector 56 from the collecting station 62 to the cleaning station 64.
[0081] In other embodiments, the cleaner may also collect the residue remaining on collector 56 by generating negative pressure. For example, the cleaner may be configured as a vacuum cleaner.
[0082] Figure 3 This is a side view of the mixing device.
[0083] Collector 56 may include a raw material inlet 66 and a raw material outlet 68. Collector 56 may be funnel-shaped. The larger diameter end of collector 56 may serve as the raw material inlet 66, and the smaller diameter end of collector 56 may serve as the raw material outlet 68. Collector 56 may extend through conveying element 58 along its axial direction. Raw material inlet 66 may be substantially flush with the upper surface of conveying element 58, and raw material outlet 68 may be located below conveying element 58. Raw material poured out from raw material package 34 may be collected by collector 56 through raw material inlet 66 and exit collector 56 through raw material outlet 68.
[0084] The mixing device 30 may also include a retainer 70. The retainer 70 may be disposed at the collection station 62 and located below the conveying element 58. The retainer 70 may include a support element 72 and an anti-tipping element 74. The support element 72 supports the container 76, and the anti-tipping element 74 prevents the container 76 from tipping over. The support element 72 and the anti-tipping element 74 may be arranged side-by-side in a vertical direction, with the support element 72 located below the anti-tipping element 74. The support element 72 may have a through-hole extending vertically, the diameter of which is smaller than the maximum diameter of the container 76. The anti-tipping element 74 may include an annular portion. The anti-tipping element 74 may include an openable clamping portion for storing, removing, or replacing the container 76. When closed, the clamping portion may define the aforementioned annular portion (including a generally annular clamping area). The container 76, such as a test tube, may be received by the clamping portion of the anti-tipping element 74, and the bottom of the container 76 may abut against the support element 72, thereby holding the container 76 at the collection station 62. At collection station 62, container 76 can be located directly below collector 56, and raw materials discharged from raw material outlet 68 can fall into container 76.
[0085] The mixing device 30 may further include a weighing element 78 and a third actuator 80. The weighing element 78 may be disposed at the collection station 62 and located below the support element 72. The third actuator 80 may be connected to the weighing element 78 and drive the weighing element 78 to reciprocate vertically; for example, the third actuator 80 may include a cylinder or an electric telescopic rod. The weighing element 78 may include a pressure sensor. When the weighing element 78 is in the lower disengagement position, the weighing element 78 can separate from the container 76 and exit through the through-hole of the support element 72, and the container 76 can be supported on the support element 72. Of course, when the weighing element 78 is in the disengagement position, the weighing element 78 may also extend into the through-hole of the support element 72. When the weighing element 78 is in the higher contact position, the weighing element 78 can extend into the through-hole of the support element 72 and abut against the bottom of the container 76, supporting the container 76, that is, the weighing element 78 bears the weight of the container 76, causing the support element 72 to separate from the container 76, that is, the support element 72 no longer supports the container 76. At this time, container 76 can apply pressure to weighing element 78, and the weighing sensor can obtain the weight of container 76 (i.e., the sum of the weight of container 76 itself and the raw materials contained in container 76) based on the pressure. After each time the receiver 48 pours raw materials into collector 56, the weighing element 78 can weigh container 76 once, thereby obtaining the weight of the raw materials poured into container 76 each time. This ensures that the weight of each added raw material meets the requirements.
[0086] The weighing sensor in this application can measure the weight of the raw materials after they enter the container, so that the measurement results are not affected by the raw materials remaining on the mixing device 30, and can accurately mix a variety of different raw materials.
[0087] When the weighing element 78 is in the measuring position, the anti-tilting element 74 can be separated from the container 76, so that the weight of the container 76 is entirely borne by the weighing element 78. In this way, the anti-tilting element 74 will not affect the measurement result of the weighing element 78. When the weighing element 78 is in the disengaged position, it can still be separated from the container 76, so that the weight of the container 76 is entirely borne by the support element 72. For example, the inner diameter of the annular portion of the anti-tilting element 74 can be larger than the outer diameter of the container 76.
[0088] In other embodiments, the support element 72 may be movable, and the weighing element 78 may be retractable. For example, the support element 72 may reciprocate vertically under the drive of a connected actuator. When the support element 72 is in a higher contact position, the container 76 may be supported on the support element 72, and the weighing element 78 may separate from the container 76 and exit through the through-hole of the support element 72. Of course, when the support element 72 is in the contact position, the weighing element 78 may also extend into the through-hole of the weighing element 72. When the support element 72 is in a lower separation position, the support element 72 may separate from the container 76, that is, the support element 72 no longer supports the container 76, and the weighing element 78 may extend into the through-hole of the support element 72 and abut against the bottom of the container 76, that is, the weighing element 78 bears the weight of the container 76.
[0089] As an alternative implementation, the support element 72 can also be configured to be retractable or tumbled. For example, when the support element 72 is in a horizontal or extended state, the container 76 can be supported on the support element 72, and the weighing element 78 can be separated from the container 76 and exit from the through hole of the element 72; when the support element 72 is in a flipped (vertical) or shortened state, the support element 72 can be separated from the container 76, that is, the support element 72 no longer supports the container 76, and the weighing element 78 can extend into the through hole of the support element 72 and rest against the bottom of the container 76, that is, the weighing element 78 bears the weight of the container 76.
[0090] In other embodiments, when the weighing element 78 is in the disengaged position, the weighing element 78 can contact the container 76, such that the support element 72 only bears part of the weight of the container 76.
[0091] In other embodiments, the annular portion of the anti-tilt element 74 may have a variable inner diameter. For example, when the weighing element 78 is in the measuring position, the anti-tilt element 74 may have a larger inner diameter, such that the anti-tilt element 74 is separated from the container 76; when the weighing element 78 is in the separated position, the anti-tilt element 74 may have a smaller inner diameter, such that the anti-tilt element 74 is in contact with the container 76.
[0092] It is understood that by setting up the conveying element 58, different collectors 56 can be switched to the collection station 62, preventing different raw materials from contaminating each other. Furthermore, by setting up the weighing element 78, a weighing sensor can measure the weight of the raw material after it enters the container 76, ensuring that the measurement results are not affected by raw materials remaining on the mixing device (e.g., raw materials remaining on the collector 56). In this way, the mixing device can accurately mix a variety of different raw materials.
[0093] Figure 4 This is a schematic diagram of the receiver.
[0094] Receiver 48 may include a fourth driver 82, a fifth driver 84, a sixth driver 86, and a flip-flop 88. The fourth driver 82 may be connected to the flip-flop 88 sequentially via the fifth driver 84 and the sixth driver 86. The fourth driver 82 may drive the fifth driver 84, the sixth driver 86, and the flip-flop 88 to rotate around a first axis 90. The fifth driver 84 may drive the sixth driver 86 and the flip-flop 88 to rotate around a second axis 92. The first axis 90 and the second axis 92 may intersect and be orthogonal. The first axis 90 may be parallel to the vertical direction, and the second axis 92 may be parallel to the horizontal direction.
[0095] The flip end 88 may include a first arm 94, a second arm 96, a first clamping part 98, and a second clamping part 100. The first arm 94 and the second arm 96 may be arranged parallel to each other and extend radially outward from the output end of the sixth driver 86 toward the first axis 90. The first clamping part 98 may be disposed at the radially outer end of the first arm 94, and the second clamping part 100 may be disposed at the radially outer end of the second arm 96. The first clamping part 98 and the second clamping part 100 may clamp the material package 34 to hold the material package 34 on the flip end 88. The first clamping part 98 and the second clamping part 100 may also release the material package 34, causing the material package 34 to separate from the flip end 88. For example, the first clamping part 98 and the second clamping part 100 may be pneumatic fingers.
[0096] After the opening is created in the raw material package 34, the fifth actuator 84 can rotate the flipping end 88 180° around the second axis 92, causing the upward opening to turn downward, thereby pouring the raw material out of the raw material package 34. The sixth actuator 86 can drive the first clamping part 98 and the second clamping part 100 to move closer and further apart from each other. When the first clamping part 98 and the second clamping part 100 are in a relatively close position, the opening of the opening on the raw material package 34 can be increased, allowing the raw material to be poured out through the opening more quickly. When the first clamping part 98 and the second clamping part 100 are in a relatively far position, the opening of the opening on the raw material package 34 can be decreased, so that the raw material cannot or can only leave the raw material package 34 through the opening more slowly. The first clamping part 98 and the second clamping part 100 can also continuously reciprocate under the drive of the sixth actuator 86, so that the flipping end 88 can pour out the raw material by vibrating the raw material package 34. Especially when the raw material is attached to the packaging, vibration can effectively separate the raw material from the packaging.
[0097] In other embodiments, during the pouring of raw materials, the fifth driver 84 may also rotate the flipping end 88 by a small angle so that the opening of the raw material package 34 faces downwards at an angle.
[0098] In other embodiments, receiver 48 may further include a vibration source for generating vibration. The vibration source may be connected to the first clamping portion 98 via a first arm 94 and to the second clamping portion 100 via a second arm 96. When the vibration source vibrates, the arms and clamping portions may transmit the vibration to the raw material package 34, thereby discharging the raw material from the raw material package 34.
[0099] Figure 5 This is a magnified view of a portion of the mixing device.
[0100] First axis 90 (see Figure 4 The flip end 88 can be arranged coaxially with the conveying element 58. By rotating about the first axis 90, the flip end 88 can be positioned at the cutting station 46 and the collecting station 62 (see...). Figure 2 Move between ).
[0101] After the raw materials are poured out of the raw material package 34, the waste box 60 and the flipping end 88 can both be moved to the cutting station 46. The first clamping part 98 and the second clamping part 100 can release the packaging of the raw material package 34, so that the entire package or the portion of the package except for fragments falls into the waste box 60.
[0102] The cutter 50 may include scissors 102 and a seventh actuator 104. The seventh actuator 104 can drive the scissors 102 to reciprocate horizontally, causing the scissors 102 to move closer to and away from the raw material package 34 received by the receiver 48. The seventh actuator 104 can also drive the two blades of the scissors 102 to open and close, enabling the scissors 102 to cut an opening in the packaging of the raw material package 34. For example, the seventh actuator 104 may be a hydraulic actuator including a solenoid valve, a speed control valve, and a hydraulic cylinder. The hydraulic cylinder may be connected to one of the blades of the scissors 102 via a transmission mechanism such as a gear and rack, thereby driving the blade to rotate. By adjusting the solenoid valve and the speed control valve, the scissors 102 can cut the packaging of the raw material package 34 with different forces and speeds.
[0103] In other embodiments, the shear 50 may include a laser, enabling the shear 50 to create an opening in the material package 34 by laser cutting. Alternatively, the shear 50 may include an ultrasonic generator, enabling the shear 50 to create an opening in the material package 34 by ultrasonic cutting.
[0104] It should be understood that the above embodiments are merely exemplary and are not intended to limit this application. Those skilled in the art can make various modifications and changes to the above embodiments under the teachings of this application without departing from the scope of this application.
