[0023] The present invention provides a transfer device for sample delivery, which includes a transceiver, a conveying device and a grabbing device; wherein the transfer device for sample delivery is divided into a plurality of working areas; each of the working areas is provided with the transceiver, and the transceiver is used to dock with a pipeline to send and receive containers; the conveying device is provided on one side of the transceiver, and the conveying device is used to transport containers between the working areas; each of the working areas is provided with the grabbing device, and the grabbing device is used to transfer containers between the transceiver and the conveying device. The transfer device is used to receive and transfer containers sent from each point, so that the docking point of each point is the transfer device, thereby reducing the pipelines required to be arranged at each point, reducing unnecessary pipeline design and the number of receiving points.

[0024] Please refer to Figures 1 to 15In one embodiment, a transfer device 100 for sample delivery is provided, which is mainly used for transferring and transporting materials. Specifically, in one embodiment, the transfer device 100 for sample delivery is used in a pneumatic sample delivery system, which is mainly used to dock with each sending point and each receiving point to transfer and transport the container, so as to reduce the number of pipelines arranged in the pneumatic sample delivery system.

[0025] The transfer device 100 for sample delivery includes a transceiver 10, a conveying device 20 and a gripping device 30. The transfer device 100 for sample delivery is divided into multiple (at least two) working areas. The transceiver 10 is provided in each of the working areas, and the transceiver 10 is used to dock with the pipeline 200 to receive and send containers 300. The conveying device 20 is provided on one side of the transceiver 10, and the conveying device 20 is used to transport the container 300 between the working areas. The gripping device 30 is provided in each of the working areas, and the gripping device 30 is used to transfer the container 300 between the transceiver 10 and the conveying device 20.

[0026] That is to say, the transceiver 10 is the part of the transfer equipment 100 for sample delivery that is used to connect with various external points, and the conveying device 20 is the part of the transfer equipment 100 for sample delivery that is used to transport and transfer the container 300, and the grasping device 30 is the part of the transfer equipment 100 for sample delivery that is used to transfer the container 300 between the transceiver 10 and the conveying device 20.

[0027] It is understandable that in the pneumatic sample delivery system of the prior art, many delivery pipelines need to be arranged for sample delivery to the sending points, and there are also many receiving points involved, which will further increase the number of pipeline arrangements. For example, when there are three sending points, three pipelines need to be set up at a single receiving point to connect with the three sending points respectively. The more receiving points and sending points there are, the more pipelines need to be arranged, which will also increase exponentially, making the pipeline arrangement in the pneumatic sample delivery system more complicated, requiring a lot of manpower, material resources and financial resources. Even when the receiving points and sending points reach a certain level, there may not be enough space to arrange the pipelines, which will affect the normal transportation of the container.

[0028] The transfer device 100 in this embodiment is divided into a plurality of work areas, and each of the work areas is provided with the transceiver 10, so that each point can be docked with the transceiver 10 through the pipeline 200. After the transceiver 10 receives the container 300, it can be sent to the conveying device 20 through the grasping device 30, so that the container 300 is conveyed to the required work area through the conveying device 20. Then, the container 300 is sent to the transceiver 10 in the work area through the grasping device 30, so that the container 300 is sent out through the transceiver 10, so as to realize the transfer of the container 300. Through the setting of the transfer device 100, the docking point of each point is the corresponding transceiver device 10 in the transfer device 100, and the container 300 is transferred through the transfer device 100, so that the container 300 received from one point can be transported to different points for sending according to needs, thereby reducing the number of pipelines required to be arranged at each point. For example, each point can only be provided with one pipeline 200 to dock with the transfer device 100, and the container 300 is transferred to the pipeline 200 to be sent through the transfer device 100, so that one point can distribute the container 300 to different receiving points as needed through one pipeline 200. Of course, when the amount of containers 300 required to be transported at a certain point is large, a pipeline 200 may be added to the point to meet the transmission needs of a large number of containers 300. Correspondingly, the transceiver 10 may be added to the transfer equipment 100 to meet the transmission needs of the point with a large amount of containers 300. However, compared with the prior art, this still reduces the setting of unnecessary pipelines.

[0029] Among them, the number of working areas divided in the transfer device 100 for sample delivery, and the number of the transceiver devices 10 and the gripping devices 30 set in each of the working areas can be selected according to actual needs. For example, in one embodiment, the transfer device 100 for sample delivery can be divided into three working areas, and the three working areas are divided into area one, area two, and area three. Area one is provided with 10 transceivers 10 and 1 gripping device 30; area two is provided with 4 transceivers 10 and 1 gripping device 30; area three is provided with 5 transceivers 10 and 2 gripping devices 30.

[0030] The container 300 is a container for containing samples to be analyzed. The specific structure of the container 300 can be found in CN217865843U, CN307849565S, etc.

[0031] Preferably, in one embodiment, each of the containers 300 is provided with a unique identity information code (which may be a QR code) so that the type of sample can be identified and monitored during operation.

[0032] In one embodiment, according to the actual on-site conditions, the transfer equipment 100 for sample delivery can be arranged in an L shape, with area one and area two placed in one row, and area three placed in another row.

[0033] In one embodiment, area one and area two can be used to interface with a process plant, and area three can be used to interface with an analysis plant.

[0034] The transceiver 10 is arranged at the pipe mouth of the pipeline 200 , and each point sends the container 300 to the transceiver 10 pneumatically through the pipeline 200 . The transceiver 10 is used to receive the container 300 and also to send the container 300 into the pipeline 200 .

[0035] Preferably, in one embodiment, the transceiver device 10 includes a transceiver unit 11 and a detection sensor 12. The detection sensor 12 is located above the transceiver unit 11, and is used to detect whether there is the container 300 on the transceiver unit 11, so that the transceiver unit 11 can be controlled to send and / or the gripping device 30 can be controlled to pick up materials according to the detection signal of the detection sensor 12.

[0036] Specifically, in one embodiment, the detection sensor 12 is a proximity switch.

[0037] Specifically, in one embodiment, a detection sensor mounting bracket 13 is further provided on the side of the transceiver unit 11 , and the detection sensor 12 is mounted on the detection sensor mounting bracket 13 .

[0038] The transceiver unit 12 may specifically adopt a structure in the prior art, such as the structure disclosed in CN115448033A, which will not be described in detail herein.

[0039] Preferably, in one embodiment, the conveying device 20 includes a conveying line 21 and a barrier 22, wherein the barrier 22 is located above the conveying line 21 and separates a flow channel 23 on the conveying line 21. The flow channel 23 is separated on the conveying line 21 by the barrier 22, and under the blocking and guidance of the barrier 22, the material on the conveying line 21 can flow in the flow channel 23, so that the material is arranged and conveyed in an orderly manner, and the collision and interference of the materials on the conveying line 21 are better avoided, the stability of the conveying is improved, and the loading and unloading of materials can also be more stable.

[0040] Preferably, in one embodiment, the barrier 22 separates a first circulation channel 231 and a second circulation channel 232 that are independent of each other on the conveying line 21. That is to say, in this embodiment, the barrier 22 separates at least two channels on the conveying line 21, and the barrier 22 separates the first circulation channel 231 and the second circulation channel 232 above the conveying line 21, so that the material can be transported in two different channels, thereby improving the transportation efficiency. And by dividing a plurality of channels through the barrier 22, materials in different states can be divided into different channels for transportation according to needs, and it can also avoid interference between materials in different states, thereby further improving the transportation efficiency. In addition, the conveying line 21 is a circulating conveying line, and these two channels are circulating channels, so that the material can circulate back and forth between various points.

[0041] Preferably, in one embodiment, the conveying line 21 includes a first conveying line 211 and a second conveying line 212 arranged side by side with the first conveying line 211, and the conveying direction of the second conveying line 212 is opposite to the conveying direction of the first conveying line 211. Figure 2 In the illustrated embodiment, the conveying direction of the first conveying line 211 is toward the upper left, while the conveying direction of the second conveying line 212 is toward the lower right.

[0042] The conveying device 20 also includes a material-dividing mechanism 24, which is mainly used to push materials and transfer materials from one conveying line to another conveying line. The material-dividing mechanism 24 includes a first material-dividing mechanism 241 and a second material-dividing mechanism 242. The first material-dividing mechanisms 241 are respectively provided at both ends of the first circulation channel 231, that is, at least two first material-dividing mechanisms 241 are provided. One of the first material-dividing mechanisms 241 is used to transfer the material in the first circulation channel 231 from the first conveying line 211 to the second conveying line 212, and the other first material-dividing mechanism 241 is used to transfer the material in the first circulation channel 231 from the second conveying line 212 to the first conveying line 211, so that the material circulates in the first circulation channel 231. For example, Figure 2 In the embodiment shown, when the material in the first circulation channel 231 on the first conveying line 211 flows to the end, the material is shifted by the first material shifting mechanism 241, so that the material is transferred from the first conveying line 211 to the second conveying line 212, and the material continues to flow along the first circulation channel 231 on the second conveying line 212; and Figure 3As shown, when the material in the first circulation channel 231 on the second conveyor line 212 flows to the end, the material will be moved by another first material moving mechanism 231, so as to transfer the material from the second conveyor line 212 to the first conveyor line 211, and let the material flow back to the first circulation channel 231 on the first conveyor line 212, so that the material can flow back and forth on the first conveyor line 211 and the second conveyor line 212.

[0043] The second material-dispensing mechanisms 242 are respectively provided at both ends of the second circulation channel 232. One of the second material-dispensing mechanisms 242 is used to transfer the material in the second circulation channel 232 from the first conveying line 211 to the second conveying line 212, and the other second material-dispensing mechanism 242 is used to transfer the material in the second circulation channel 232 from the second conveying line 212 to the first conveying line 211. Similarly, when the material in the second circulation channel 232 on the first conveying line 211 flows to the end, it will be transferred to the second conveying line 212 through one of the second material-dispensing mechanisms 242; when the material in the second circulation channel 232 on the second conveying line 212 flows to the end, it will be transferred to the first conveying line 211 through another of the second material-dispensing mechanisms 242, so that the material can flow back and forth on the first conveying line 211 and the second conveying line 212.

[0044] Specifically, in one embodiment, the material is a carrier 400 disposed on the conveying device 20 for loading the container 300. The carrier 400 is provided with a receiving hole 410, and the carrier 400 can receive the container 300 for the sample to be analyzed through the receiving hole 410. After the container 300 is transported from the pipeline 200 to the transceiver 10, it can be sent into the carrier 400 through the gripping device 30, and flow on the conveying device 20 through the carrier 400, thereby driving the container 300 to flow and transport the container 300 to another pipeline 200. More specifically, after the container 300 is loaded into the carrier 400, the bottom of the container 300 will be located in the receiving hole 410, and the top of the container 300 will extend out of the carrier 400, that is, a part of the container 300 will be located outside the carrier 400, so as to facilitate the gripping device 30 to pick up and place.

[0045] Specifically, in one embodiment, the first circulation channel 231 and the second circulation channel 232 are arranged side by side and adjacent to each other, the first circulation channel 231 is located on the inner side, and the second circulation channel 232 is located on the outer side.

[0046] Specifically, in one embodiment, the second circulation channel 232 is a sending channel, and the container 300 containing the sample is sent from the process plant to the first area and the second area, and then transferred to the third area through the conveying line 21 through the second circulation channel 232, and finally sent to the analysis plant. The first circulation channel 231 is a return channel, and the analysis plant sends back the empty container 300 without the sample to the third area, and then transfers to the first area or the second area through the conveying line 21 through the first circulation channel 231, and finally sends it back to the process plant.

[0047] Preferably, in one embodiment, the first material-dispensing mechanism 241 includes a first drive motor 2411 and a turntable 2412, wherein the turntable 2412 is disposed on the output shaft of the first drive motor 2411, and the outer periphery of the turntable 2412 is recessed to form a material-dispensing cavity 2413, and the material-dispensing cavity 2413 is used to accommodate materials. That is to say, in this embodiment, the first material-dispensing mechanism 241 itself can provide power to drive the material to move, rather than relying entirely on the inertia of the material being transmitted on the conveyor line. When the material flows to the first material-dispensing mechanism 241, it will flow into the material-dispensing cavity 2413 accordingly, and the turntable 2412 will be driven to rotate by the first drive motor 2411, so that the turntable 2412 will drive the material to rotate, and transfer the material from one conveyor line to another.

[0048] Specifically, in one embodiment, an annular groove 420 is opened on the outer periphery of the carrier 400, and the material transfer cavity 2413 is an annular cavity. When the carrier 400 flows into the material transfer cavity 2413, the turntable 2412 will be correspondingly inserted into the annular groove 420, so that the carrier 400 can be transferred and transported more stably.

[0049] Preferably, in one embodiment, a plurality of the material-selecting cavities 2413 are sequentially arranged at intervals along the circumference of the turntable 2412 , thereby further improving the transfer efficiency.

[0050] Preferably, in one embodiment, the first material shifting mechanism 241 further includes an arc-shaped baffle 2414, which is located outside the turntable 2412 and spaced apart from the turntable 2412. When the turntable 2412 transfers materials, the arc-shaped baffle 2414 can block and limit the materials from the outside, thereby preventing the materials from escaping from the turntable 2412, thereby improving the reliability of the first material shifting mechanism 241 in transferring materials.

[0051] Specifically, in one embodiment, the first driving motor 2411 is a servo motor.

[0052] Specifically, in one embodiment, in order to avoid interference between the first conveying line 211 and the second conveying line 212, the first conveying line 211 and the second conveying line 212 can be arranged side by side and spaced apart. A support plate 25 can be arranged below the first material shifting mechanism 241 and the second material shifting mechanism 242 to support the material when the first material shifting mechanism 241 and the second material shifting mechanism 242 transfer the material to prevent the material from falling.

[0053] Preferably, in one embodiment, the second material shifting mechanism 242 includes a second driving motor 2421, a driving wheel 2422, a driven wheel assembly 2423, a transmission belt 2424, and a shifting rod 2425. The driving wheel 2422 is arranged on the output shaft of the second driving motor 2421, the driven wheel assembly 2423 is arranged relatively spaced from the driving wheel 2422, and the transmission belt 2424 is wound around the driving wheel 2422 and the driven wheel 24231 of the driven wheel assembly 2423. The shifting rod 2425 is arranged on the transmission belt 2424 to push the material to move. That is to say, in this embodiment, the second material shifting mechanism 242 itself can provide power to drive the material to move, rather than relying entirely on the inertia of the material being transmitted on the conveyor line. The second driving motor 2421 drives the driving wheel 2422 to rotate, thereby driving the transmission belt 2424 to run, thereby driving the shifting rod 2425 to move. When the material flows to the second material shifting mechanism 242, the material is pushed by the shifting rod 2425, thereby transferring the material from one conveyor line to another.

[0054] Specifically, in one embodiment, when the lever 2425 is at the bottom of the transmission belt 2424, the height of the lever 2425 is flush with the height of the annular groove 420 on the carrier 400, so that the lever 2425 can be pushed into the annular groove 420 to push the carrier 400. When the lever 2425 is at the top of the transmission belt 2424, the height of the lever 2425 is higher than the carrier 400, so that when the lever 2425 moves back, it will not interfere with the carrier 400.

[0055] Specifically, in one embodiment, the second driving motor 2421 is a servo motor.

[0056] Preferably, in one embodiment, the second material-dispensing mechanism 242 further includes a base 2426, and the second driving motor 2421 and the driven wheel assembly 2423 are respectively arranged on the base 2426. The driven wheel assembly 2423 further includes a connecting shaft 24232 and a bearing 24233, wherein the connecting shaft 24232 is connected to the driven wheel 24231, and the connecting shaft 24232 is mounted on the base 2426 via the bearing 24233. This structure can more stably support the driven wheel 24231 and better avoid wear between components.

[0057] Preferably, in one embodiment, a plurality of the shifting rods 2425 are provided on the transmission belt 2424, thereby further improving the transfer efficiency.

[0058] Preferably, in one embodiment, two transmission belts 2424 are arranged in parallel and spaced apart, and the lever 2425 is connected to the two transmission belts 2424 via a chain 2427. This structure can improve the connection reliability between the lever 2425 and the transmission belt 2424.

[0059] Preferably, in one embodiment, the barrier 22 further separates a third flow channel 233 above the conveying line 21, and the third flow channel 233 is adjacent to the second circulation flow channel 232; a first notch 221 is provided on the barrier 22 between the third flow channel 233 and the second circulation flow channel 232, and the first notch 221 connects the third flow channel 233 and the second circulation flow channel 232; The conveying device 20 further includes a channel changing mechanism 26, which is rotatably disposed at the first notch 221, and the channel changing mechanism 26 can be transferred into the second circulation channel 232 to block and guide the material in the second circulation channel 232, so that the material flows into the third channel 233 through the first notch 221. That is, in this embodiment, the channel changing mechanism 26 can guide and change the material, for example, Figure 4As shown, at this time, the channel-changing mechanism 26 is located in the second circulation channel 232, so that when the material in the second circulation channel 232 flows to the channel-changing mechanism 26, it will be blocked and guided by the channel-changing mechanism 26, and the material will be guided to the first notch 221, and flow into the third channel 23 through the first notch 221, thereby switching the flow path of the material. When it is not necessary to guide the material in the second circulation channel 232 to the third channel 233, the channel-changing mechanism 26 can be driven to rotate, so that the channel-changing mechanism 26 rotates out of the second circulation channel 232, so that the channel-changing mechanism 26 is flush with the blocking member 22, so that the normal flow of the material in the second circulation channel 232 will not be affected.

[0060] Preferably, in one embodiment, a second notch 222 is further provided on the barrier 22 between the third flow channel 233 and the second circulation flow channel 232, and the second notch 222 connects the third flow channel 233 with the second circulation flow channel 232. A guide 27 is provided in the third flow channel 233 corresponding to the second notch 222. The guide 27 can block and guide the material in the third flow channel 23, guide the material to the second notch 222, and flow into the second circulation flow channel 232 through the second notch 222, so that the material in the third flow channel 233 can be switched to the second circulation flow channel 232.

[0061] In one embodiment, the material in the third flow channel 233 does not participate in the circulation. The third flow channel 233 can be used to transport the empty carrier 400 (or the carrier 400 loaded with the container 300), and the third flow channel 233 can be used as a loading flow channel (or a material removal flow channel), so that each time the grabbing device 30 transports the container 300 to the conveying device 20 (or grabs the container 300), it can enter the third flow channel 233 to load (or remove) the container 300.

[0062] Specifically, in one embodiment, the third flow channel 233 may be provided with a plurality of channels, and the function of each of the third flow channels 233 may be selected according to the requirements. For example, the third flow channels 233 may be provided at the positions of the first zone, the second zone, and the third zone, respectively. The third flow channels 233 located in the first zone and the second zone may be used as a material loading channel, while the third flow channel 233 located in the third zone may be used as a material taking channel. When the third flow channels 233 are provided with a plurality of channels, the components and structures on the conveying device 20 used to cooperate with the third flow channels 233 also need to be provided with a plurality of channels to meet the corresponding functional requirements.

[0063] Preferably, in one embodiment, the third flow channel 233 is located on a side of the conveying line 21 close to the transceiver 10 .

[0064] Preferably, in one embodiment, the channel changing mechanism 26 comprises a bracket 261, a material dividing plate 262 and a driving unit 263, wherein the material dividing plate 262 is rotatably connected to the bracket 261, that is, the material dividing plate 262 is connected to the bracket 261, and the material dividing plate 262 can rotate relative to the bracket 261. The output end of the driving unit 263 is connected to the material dividing plate 262, and the driving unit 263 is used to drive the material dividing plate 262 to rotate, so that the material dividing plate 262 is transferred into the flow channel of the conveying device to block and guide the material in the flow channel. That is to say, the driving unit 263 is the power source for driving the dividing plate 262 to rotate. The driving unit 263 provides power, thereby prompting the dividing plate 262 to rotate around the connection point with the bracket 261, allowing the dividing plate 262 to move into the flow channel, so that the dividing plate 262 will block and guide the material in the flow channel to change the flow direction of the material and prompt the material to flow into another flow channel.

[0065] When the lane-changing mechanism 26 is in operation, after the driving unit 263 receives the corresponding control signal from the controller in the conveying device, it drives the dividing plate 262 to rotate, so that the dividing plate 262 is transferred into a flow channel in the conveying device, so that when the material flows in this flow channel, it will be blocked and guided by the dividing plate 262, so that the material is introduced into another flow channel, so as to realize the controlled lane-changing of the material. When the material that needs to be changed is changed, the controller in the conveying device 20 sends a corresponding control signal, so that the driving unit 263 drives the dividing plate 262 to reset, so that the dividing plate 262 is withdrawn from the flow channel, so that the material in the flow channel can continue to be normally transported. The lane-changing mechanism 26 can quickly realize the switching flow of materials between different flow channels, which can meet the transportation requirements and improve the transportation efficiency.

[0066] Preferably, in one embodiment, the lane changing mechanism 26 further includes a mounting plate 264, and the bracket 261 and the driving unit 263 are respectively arranged on the mounting plate 264. Through the arrangement of the mounting plate 264, the bracket 261, the driving unit 263, and the material dividing plate 262 form an integral structure, which can make the lane changing mechanism 26 more convenient to install and make the overall structure more compact.

[0067] Preferably, in one embodiment, the driving unit 263 includes a motor 2631, a gear 2632 and a rack assembly 2633, the gear 2632 is arranged on the output shaft of the motor 2631, the rack assembly 2633 is meshed with the rack assembly 2633, and the rack assembly 2633 is connected to the material dividing plate 262. When it is necessary to drive the material dividing plate 262 to rotate, the motor 2631 drives the gear 2632 to rotate, so that the gear 2632 drives the rack assembly 2633 to move linearly, and the linear movement of the rack assembly 2633 drives the material dividing plate 262 to rotate. Of course, in other embodiments, the driving unit 263 can also adopt other arbitrary linear drive structures, as long as it can drive the material dividing plate 262 to rotate. In this embodiment, the transmission form of the motor driving the gear rack is adopted, which can improve the control accuracy and more accurately control the rotation angle of the material dividing plate 262. More preferably, in one embodiment, the motor 2631 is a servo motor.

[0068] Specifically, in one embodiment, the rack assembly 2633 includes a rack 26331, a mounting block 26332, and a connecting frame 26333, the rack 26331 is meshed with the gear 2632, the mounting block 26332 is connected to the rack 26331, and the connecting frame 26333 is respectively connected to the mounting block 26332 and the material dividing plate 262. When driving, the motor 2631 drives the gear 2632 to rotate, so that the gear 2632 drives the rack 26331 to move, and the rack 26331 synchronously drives the mounting block 26332 and the connecting frame 26333 to move, and outputs power to the material dividing plate 262 through the connecting frame 26333, so that the material dividing plate 262 rotates.

[0069] Preferably, in one embodiment, one end of the material dividing plate 262 is rotatably connected to the bracket 261, and the connecting frame 26333 is connected to the top of the material dividing plate 262. By connecting the connecting frame 26333 to the top of the material dividing plate 262, it is possible to better avoid the connecting frame 26333 from interfering with the material in the flow channel and affecting the normal transportation of the material.

[0070] Specifically, in one embodiment, the dividing plate 262 is connected to the bracket 261 via a hinge, thereby achieving a rotatable connection between the dividing plate 262 and the bracket 261 .

[0071] More preferably, in one embodiment, the connecting frame 26333 includes a first frame 263331, a second frame 263332, a third frame 263333 and a fourth frame 263334, wherein the first frame 263331 is connected to the mounting block 26332. The second frame 263332 is arranged in a vertical direction, and the bottom end is connected to the first frame 263331. The third frame 263333 is arranged in a horizontal direction, and one end is connected to the top end of the second frame 263332. The fourth frame 263334 is arranged in a vertical direction, and the top end is connected to the other end of the third frame 263333, and the bottom end is connected to the top of the dividing plate 262. This structure can raise the height of the third frame 263333, thereby further preventing the third frame 263333 arranged in the horizontal direction from interfering with the material in the flow channel, so that the material can flow smoothly from under the third frame 263333. At the same time, this structure can also ensure that the connecting frame 26333 is stably connected to the material dividing plate 262, ensuring that the rack assembly 2633 can drive the material dividing plate 262 to rotate.

[0072] Preferably, in one embodiment, a slide rail 2641 is provided on the mounting plate 264, and a slider is provided on the rack assembly 2633, and the slider is slidably provided on the slide rail 2641. By providing the slide rail 2641 and the slider, when the gear 2632 drives the rack assembly 2633 to move, the moving direction of the rack assembly 2633 can be more accurately guided, and the wear between the components can be reduced.

[0073] Preferably, in one embodiment, the bracket 261 includes a first bracket body 2611, a second bracket body 2612, a third bracket body 2613 and a fourth bracket body 2614, wherein the first bracket body 2611 is connected to the mounting plate 264. The second bracket body 2612 is arranged in a vertical direction, and the bottom end is connected to the first bracket body 2611. The third bracket body 2613 is arranged in a horizontal direction, and one end is connected to the top end of the second bracket body 2612. The fourth bracket body 2614 is arranged in a vertical direction, and the top end is connected to the other end of the third bracket body 2613. The material dividing plate 262 is rotatably connected to the bottom end of the fourth bracket body 2614. Similarly, in this embodiment, the height of the third bracket body 2613 can be raised through this structure, so that the third bracket body 2613 arranged in a horizontal direction can be further prevented from interfering with the material in the flow channel, so that the material can flow smoothly from the bottom of the third bracket body 2613. At the same time, this structure can also ensure that the dividing plate 262 is stably connected to the bracket 261.

[0074] Preferably, in one embodiment, a detection mechanism 28 may also be provided in the conveying device 20, and the detection mechanism 28 is used to detect the material, thereby outputting a corresponding signal to the controller of the conveying device 20, thereby controlling the operation of corresponding components in the conveying device 20 (such as the lane changing mechanism 26).

[0075] Specifically, in one embodiment, the detection mechanism 28 is mainly used to detect whether the carrier 400 on the conveyor line 21 carries and contains the container 300. For example, when the detection mechanism 28 detects that the carrier 400 is an empty carrier (without a container), a corresponding signal is output to prompt the material dividing plate 262 to rotate into the second circulation channel 232, so that the empty carrier 400 flows from the second circulation channel 232 into the third flow channel 233; it can also be that when the detection mechanism 28 detects that the carrier 400 is loaded with the container 300, a corresponding signal is output to prompt the material dividing plate 262 to rotate into the second circulation channel 232. Of course, in other embodiments, the sensor can also be used to detect other targets according to needs, and it can be selected according to actual needs. In addition, the detection mechanism 28 can also detect the position of the carrier 400 in the flow channel to feedback whether the carrier 400 has flowed through a certain area.

[0076] Preferably, in one embodiment, the detection mechanism 28 includes a mounting member 281, a first position detection sensor 282 and a second position detection sensor 283, wherein the first position detection sensor 282 and the second position detection sensor 283 are respectively arranged on the mounting member 281. The detection height of the second position detection sensor 283 is higher than the detection height of the first position detection sensor 282, that is, the detection areas of the second position detection sensor 283 and the first position detection sensor 282 are at different heights, so that components at different heights can be detected. The first position detection sensor 282 is used to detect materials, and the second position detection sensor 283 is used to detect the container 300 contained on the material. In other words, the second position detection sensor 283 is used to detect whether the material contains a container 300. When the material contains a container 300 and the container 300 follows the material to flow through the detection mechanism 28 for sample delivery, the detection area of ​​the second position detection sensor 283 just corresponds to the container 300, so that the corresponding signal can be detected.

[0077] By setting the first position detection sensor 282 and the second position detection sensor 283 with detection areas at different heights, the state of the material flowing through can be detected. When the material flowing through does not contain a container 300, only the first position detection sensor 282 can detect the signal; and when the material flowing through contains a container 300, both the first position detection sensor 282 and the second position detection sensor 283 can detect the signal. In this way, the state of the material flowing through can be detected, which is conducive to the subsequent corresponding processing of the material (such as diversion, loading, and taking).

[0078] Preferably, in one embodiment, the first position detection sensor 282 is tilted. By tilting the first position detection sensor 282, it is possible to better avoid interference between the first position detection sensor 282 and other components, which is beneficial to the arrangement of the detection mechanism 28 on the conveying device 20, and can also well detect the material on the flow channel.

[0079] Preferably, in one embodiment, the mounting member 281 includes a base 2811 and a fixing plate 2812 disposed on the base 2811, and the fixing plate 2812 includes a first connecting plate 28121, a first mounting plate 28122, and a second mounting plate 28123. The first connecting plate 28121 is connected to the base 2811, the first mounting plate 28122 is connected to the first connecting plate 28121, and the second mounting plate 28123 is connected to the first mounting plate 28122. The first position detection sensor 282 is disposed on the first mounting plate 28122, and the second position detection sensor 283 is disposed on the second mounting plate 28123. This structure allows the first position detection sensor 282 and the second position detection sensor 283 to be more stably mounted on the mounting member 281.

[0080] Preferably, in one embodiment, the first mounting plate 28122 is tilted. By tilting the first mounting plate 28122, it is easy to install the first position detection sensor 282. In particular, when the first position detection sensor 282 needs to be tilted, by tilting the first mounting plate 28122, the difficulty of installing the first position detection sensor 282 can be further reduced, and the connection reliability between the first position detection sensor 282 and the first mounting plate 28122 can also be improved.

[0081] Preferably, in one embodiment, a first waist-shaped groove 28124 is provided on the first mounting plate 28122, and the first position detection sensor 282 is arranged at the first waist-shaped groove 28124. The provision of the first waist-shaped groove 28124 can facilitate the installation of the first position detection sensor 282, and can also facilitate the adjustment of the position of the first position detection sensor 282, ensuring that the detection area of ​​the first position detection sensor 282 can correspond to the area where the material flows after installation. A second waist-shaped groove 28125 is provided on the second mounting plate 28123, and the second position detection sensor 283 is arranged at the second waist-shaped groove 28125. Similarly, the provision of the second waist-shaped groove 28125 can facilitate the installation and debugging of the second position detection sensor 283, ensuring that the detection area of ​​the second position detection sensor 283 can correspond to the area where the container flows after installation. Specifically, in one embodiment, the first waist-shaped groove 28124 and the second waist-shaped groove 28125 extend in the vertical direction, so that the height of the first position detection sensor 282 and the second position detection sensor 283 can be adjusted.

[0082] Preferably, in one embodiment, the first position detection sensor 282 and the second position detection sensor 283 are both proximity switches. That is, in this embodiment, both position detection sensors are non-contact sensors, thereby avoiding interference with the normal flow of the material. At the same time, the proximity switch also has good detection performance and can accurately feedback the state of the material.

[0083] Preferably, in one embodiment, the conveying device 20 further comprises a material blocking mechanism 29, the blocking arm of which is located above the conveying line 21, for blocking the carrier 400 in the flow channel. The material blocking mechanism 29 can be provided in each flow channel above the conveying line 21 according to the requirements, and when the corresponding carrier 400 needs to be stopped, the blocking arm of the material blocking mechanism 29 extends into the flow channel, thereby blocking the carrier 400, so as to facilitate loading, taking out or other operations.

[0084] Specifically, in one embodiment, the material blocking mechanism 29 may specifically adopt any structure capable of achieving material blocking, for example, the structure disclosed in CN116101764A.

[0085] In addition, in one embodiment, a detection sensor and the material blocking mechanism 29 may also be provided in the position of the third flow channel 233 on the rear side of the lane changing mechanism 26. The detection sensor and the material blocking mechanism 29 cooperate with each other to stop the carrier 400 as needed to prevent the carriers 400 from crowding in the third flow channel 233.

[0086] Among them, in one embodiment, two adjacent blocking mechanisms 29 can be set at the feeding and picking positions on the conveyor line 21. For the convenience of description, the two blocking mechanisms 29 are divided into a first blocking mechanism and a second blocking mechanism. For example, when the carrier 400 flows to the feeding position, the first blocking mechanism extends to stop the carrier 400. After the gripping device 30 puts the container 300 into the first carrier 400, the first blocking mechanism is retracted to release the first carrier 400 containing the container 300; at the same time, the second blocking mechanism stops the empty carrier 400 behind, and after the carrier 400 containing the container 300 flows out of the stopping area, the first blocking mechanism performs the stopping, the second blocking mechanism is retracted, and the empty carrier 400 is in a state of waiting to receive the container 300. Similarly, two blocking mechanisms are also set at the picking position, and the release is achieved one by one through the cooperation between the two blocking mechanisms. Preferably, in one embodiment, a sensor is provided on the first material blocking mechanism, and the sensor can detect whether the container 300 is placed on the first carrier 400, so as to facilitate subsequent execution of actions. The sensor can be a proximity switch. In addition, in other embodiments, two blocking arms can be provided in one material blocking mechanism 29, and the two blocking arms can cooperate to realize one-by-one release.

[0087] Preferably, in one embodiment, the transfer device 100 further includes a code scanning device 40, which is arranged on the transceiver 10 and / or the gripper 30, so that when the container 300 flows into the transfer device 100, the identity of the container 300 can be identified by the code scanning device 40, so that the container 300 can be sent to the corresponding flow channel on the conveyor line 21 for conveying by the gripper 30. In addition, the code scanning device 40 is also arranged on the conveyor 20, specifically above the conveyor 21, and the detection area faces the conveyor 21, so as to scan the information code of the container 300 on the material conveyed on the conveyor 21. The container 300 is identified by the code scanning device 40, so that the gripper 30 can be controlled to transfer the container 300 to the corresponding transceiver 10, and the corresponding structure on the conveyor 20 can also be controlled to operate. In addition, by identifying the container 300, the transfer device 100 can also transport the container 300 according to the priority. For example, when the code scanning device 40 scans the container 300 with the highest priority, it can output a corresponding signal to the controller, so that the controller controls the corresponding components in the conveying device 20 to operate. For example, when the container 300 with the highest priority enters the conveying device 20, the components on the conveying device 20 release all containers 300 before the container 300 with the highest priority, allowing other containers to continue to circulate on the conveying line 21, and the material blocking mechanism 29 does not extend to block the material, and only blocks the material when the code scanning device 40 scans the container 300 with the highest priority flowing through, thereby ensuring that the container 300 with the highest priority can be taken at the fastest time. Alternatively, the code scanning device 40 may be located in front of the lane-changing mechanism 26. When the container 300 with the highest priority enters the conveying device 20, the various components on the conveying device 20 release all containers in front of the container 300 with the highest priority, allowing other containers to continue to circulate on the conveying line 21. Only when the code scanning device 40 scans the container 300 with the highest priority flowing through, the lane-changing mechanism 26 is controlled to switch to the material-collecting flow channel, thereby introducing the container 300 with the highest priority into the material-collecting flow channel for material collection. In other words, the container 300 can be identified through the setting of the code scanning device 40, and the corresponding detection signal can be output to the controller, which controls the various components to improve the conveying efficiency of the specific container 300.

[0088] Specifically, in one embodiment, the information code on the container 300 is a two-dimensional code, and the code scanning device 40 is a two-dimensional code scanner. More specifically, in one embodiment, the code scanning device 40 can be installed on a support frame 50.

[0089] Specifically, the gripping device 30 may adopt a manipulator structure. Preferably, in one embodiment, the gripping device 30 includes a gripping bracket 31 and a gripping manipulator 32. The gripping manipulator 32 is a three-axis mobile manipulator. The gripping manipulator 32 includes a manipulator bracket 321 and a Y-axis moving mechanism 322, an X-axis moving mechanism 323, a Z-axis moving mechanism 324 and a clamping unit 325 installed on the manipulator bracket 321. The X, Y and Z axes are perpendicular to each other. The clamping unit 325 is used to clamp the container 300. Among them, a moving gear is provided on the Y-axis moving mechanism 322, and a rack is provided on the bracket 31. The moving gear is meshed with the rack, so that the moving gear is driven to rotate, thereby driving the whole to move on the bracket 31. A guide rail and a slider can also be provided between the bracket 31 and the Y-axis moving mechanism 322 for guidance and support.

[0090] Through the detection equipment such as the code scanning device 40 and the detection mechanism 28, the system can count the containers 300 loaded in the first and second zones, and perform detection and verification in the third zone, monitor and alarm abnormal situations such as the containers 300 falling in the carrier 400 during the placement and transportation of the containers 300, for example, by comparing the number of the placed containers 300 and the number of carriers 400 loaded with the containers 300 detected by the detection mechanism 28, it can be determined whether the container 300 has fallen on the carrier 400. After an abnormal situation such as a fall occurs, the equipment can be shut down and sorted.

[0091] The transfer equipment 100 for sample delivery can count the maximum sending volume and handling volume of each device in sections, find the bottleneck value, take the bottleneck value as the transfer volume that the system can achieve, and set a reasonable number of the carriers 400 to operate on the flow channel of the conveyor line 21.

[0092] The transfer device 100 for sample delivery is docked with each point through each pipeline 200, and the container 300 sent from each point is first sent to the transfer device 100 for sample delivery through the pipeline 200, and then after being transported and distributed by the transfer device 100 for sample delivery, the container 300 is transported to the receiving point through another pipeline 200. The setting of the transfer device 100 for sample delivery can reduce the number of pipelines required to be arranged in the pneumatic sample delivery system, reducing unnecessary pipeline design and the number of receiving points.

[0093] At the same time, in one embodiment, a delivery method is also provided, which uses the transfer device 100 for sample delivery. The delivery method comprises the following steps: Receiving materials: the receiving and sending device 10 in a working area receives the delivered container 300, and delivers the container 300 to the conveying device 20 through the gripping device 30 in the working area; Transfer: The conveying device 20 transfers the container 300 to another work area; Feeding: The gripping device 30 in another work area transfers the container 300 in the conveying device 20 to the sending and receiving device 10 in the work area, and the sending and receiving device 10 in the work area sends out the container 300.

[0094] Preferably, in one embodiment, the material receiving step specifically includes the following steps: after the container 300 is sent to the transceiver 10, the detection sensor 12 on the transceiver 10 senses the arrival of the container 300, and the gripping device 30 clamps the container 300 to the first empty carrier 400 that is stopped and waiting by the material blocking mechanism 29 on the flow channel (for example, the third flow channel 233). After the sensor on the first material blocking mechanism 29 (or the first blocking arm on the material blocking mechanism 29) senses the presence of the container 300, the first material blocking mechanism 29 executes an action to retract and releases the first carrier 400 containing the container 300, and the carrier 400 containing the container 300 continues to be transported backward (for example, from the third flow channel 233 into the second circulation flow channel 232) to other working areas.

[0095] Preferably, in one embodiment, the material receiving step further includes the following steps: the code scanning device 40 scans the container 300 to determine the sending position, and controls the grasping device 30 to select the flow channel for placement.

[0096] Preferably, in one embodiment, the transfer step also includes the following steps: the conveying line 21 transports the carrier 400 loaded with the container 300 to another work area, and after the detection mechanism 28 detects that the carrier 400 is loaded with the container 300, it controls the lane changing mechanism 26 to operate and transfer the carrier 400 into the third flow channel 233 to wait for sending.

[0097] Specifically, in one embodiment, in the transfer step, when the container 300 is transferred to a material taking area of ​​another work area, it is stopped by the material blocking mechanism 29 .

[0098] Preferably, in one embodiment, the feeding step specifically includes the following steps: after the sensor on the blocking mechanism 29 located in the material picking area in the working area confirms the presence of the container 300, the code scanning device 40 scans and determines which docking point to send to, and then the grasping device 30 clamps the container 300 to the corresponding transceiver device 10 and then sends it to the corresponding factory building; then the blocking mechanism 29 performs an action, the first blocking mechanism 29 (or the first blocking arm of the blocking mechanism 29) is retracted, and the empty carrier 400 is released, and the empty carrier 400 continues to be transmitted backward on the conveyor line 21, and the second blocking mechanism 29 (or the second blocking arm of the blocking mechanism 29) blocks the carrier 400 carrying the container 300 behind, and after the empty carrier 400 flows out of the blocking area, the blocking mechanism 29 performs an action, the first one performs a blocking, and the second one is retracted, and the carrier 400 carrying the container 300 is in a waiting state again.

[0099] For example, in a specific embodiment, after the sensor detects the carrier 400 loaded with the empty container 300, the code scanning device 40 performs scanning to determine the sending position. If the sending is in zone 1, the gripping device 30 clamps the empty container 300 to the corresponding transceiver 10, and at the same time, the blocking mechanism 29 performs an action, the first one is retracted to release the empty carrier 400, and the second one stops the carrier 400 loaded with the container 300 behind. If the sending is in zone 2, it is also released. After the carrier 400 flows out of the blocking area, the blocking mechanism 29 performs an action, the first one is stopped, and the second one is retracted. The carrier 400 loaded with the empty container 300 is in the waiting state for sending again. The configuration of zone 2 is the same as that of zone 1, and the method is the same, except that the detection mechanism 28 directly releases the empty carrier 400 if it detects it is empty.

[0100] The transfer equipment 100 for sample delivery can prioritize the transfer scheduling according to the priority rules of the samples to be sent, that is, the highest priority sample in the queue will be sent first, and the low-level samples before this sample will be directly released to continue to circulate online, so as to ensure that high-priority samples with time requirements are sent to the destination first; if the destination is blocked, other samples that need to be analyzed can be scheduled for delivery first. Preferably, in one embodiment, in the material receiving step, the code scanning device 40 on the transceiver 10 or the gripping device 30 scans the information code on the container 300 and sends the corresponding information to the controller; the controller determines the priority of the current container 200, and if the priority of the current container 200 is high, it controls the execution component in the conveying device 20 to release all containers 300 before the current container 300; In the transfer step, when the barcode scanning device 40 on the conveying device 20 scans the container 300 with a high priority, the controller controls the execution component to run, and the container 300 with a high priority is divided into other flow channels or blocked.

[0101] The transfer equipment 100 for sample delivery can perform global intelligent scheduling according to the priority of the delivery task, and the whole delivery process is unmanned. The sample identity is automatically scanned and identified, and it is automatically sent and intelligently transferred and sorted, which solves the low efficiency problem of manual or traditional single-point sample delivery. The whole process of material and equipment information is tracked, the delivery process is visualized, and the delivery data can be traced back, realizing centralized management, and preventing problems such as sample loss and wrong delivery.

[0102] The above description is only an implementation mode of the present invention. It should be pointed out that, for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present invention, but these all belong to the protection scope of the present invention.
