Description

Technical Field

[0001] This invention relates to the field of tobacco physical index detection technology, and in particular to an intelligent sample delivery device. Background Technology

[0002] Currently, there are two types of sampling methods for test samples: manual sampling and automatic sampling. Manual sampling involves personnel manually retrieving samples from the production line and then placing them on a comprehensive testing platform for testing. This method increases labor costs, and manual sampling can also cause varying degrees of compression to the samples, altering their physical properties and affecting test results. Automatic sampling involves placing the comprehensive testing platform near the production line and equipping it with a fixed automatic sampling device. The automatic sampling device retrieves samples from the production line and delivers them to the comprehensive testing platform for testing. However, since production line heights vary, the automatic sampling device must be installed and adjusted according to the actual height. Furthermore, limited space near the production line sometimes prevents the placement of a comprehensive testing platform, thus limiting the online sampling and testing methods.

[0003] Therefore, there is an urgent need for a device that can assist in the sampling and delivery process. Summary of the Invention

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0029] In the description of the embodiments of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of the present invention.

[0030] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] The following is combined Figures 1 to 2 This invention describes the intelligent sample delivery device provided by the present invention.

[0032] like Figure 1 As shown, the intelligent sample delivery device provided in this embodiment of the invention includes: a device body 1, a motion mechanism 3, and a sampling mechanism 2. The device body 1 is the main part of the entire intelligent sample delivery device. The motion mechanism 3 is located at the bottom of the device body 1 and can be a trolley used to drive the entire intelligent sample delivery device to move. The sampling mechanism 2 is located on the device body 1 and is used to cooperate with the motion mechanism 3 to complete sampling and delivery.

[0033] Specifically, such as Figure 1 and Figure 2As shown, the sampling mechanism 2 includes a rotating disk 21, a buffer slot 22, a pusher 23, a first drive 24, a second drive 25, and a third drive 26. The buffer slot 22 is used to store the sample collected. The rotating disk 21 includes a fixed disk 211 and a turntable 212 rotatable relative to the fixed disk 211. Both the fixed disk 211 and the turntable 212 are mounted on the main body 1 of the device. The buffer slot 22 is mounted on the turntable 212. The first drive 24 is driven by the turntable 212 and the fixed disk 211, and is used to drive the turntable 212, the fixed disk 211, and the buffer slot 22 to move vertically. The second drive 25 is driven by the turntable 212, and is used to drive the turntable 212 to rotate relative to the fixed disk 211. The pusher 23 is mounted on the fixed disk 211, and the third drive 26 is driven by the pusher 23, and is used to control the movement of the pusher 23 in the buffer slot 22.

[0034] The specific workflow of the intelligent sample delivery device is as follows:

[0035] The motion mechanism 3 is responsible for driving the entire intelligent sample delivery device to move. At the same time, the motion mechanism 3 can go to the charging positioning point to charge. After receiving the work task, it will travel back and forth between the online sampling system and the integrated test bench to collect and deliver samples. It will stop running after reaching any positioning point corresponding to the online sampling system and the integrated test bench.

[0036] During sampling, driven by the motion mechanism 3, the intelligent sample delivery device reaches the corresponding positioning point of the online sampling system. After the motion mechanism 3 precisely positions the intelligent sample delivery device to the positioning point, the first driving component 24 drives the turntable 212, the fixed plate 211, and the buffer slot 22 to move vertically, aligning the buffer slot 22 with the online sampling system. After alignment, the online sampling system delivers the sample into the buffer slot 22. If further sampling is needed (assuming multiple buffer slots are provided), the second driving component 25 drives the turntable 212 to rotate relative to the fixed plate 211, causing the buffer slot 22 without a sample to switch to the sampling position for the next set of sampling. Once multiple buffer slots 22 are full, sampling stops, and the device prepares to move to the positioning point of the integrated testing platform. The intelligent sample delivery device can fill one online sampling point at once, fill multiple online sampling points, or not fill them completely; it can deliver samples to the positioning point of the integrated testing platform as soon as it receives an instruction.

[0037] When delivering samples, the intelligent sample delivery device reaches the positioning point of the integrated testing platform. The motion mechanism 3 precisely positions the intelligent sample delivery device to the positioning point. The first driving component 24 drives the turntable 212, the fixed plate 211, and the buffer slot 22 to move vertically, so that the buffer slot 22 aligns with the integrated testing platform. After alignment, the third driving component 26 controls the pushing component 23 to move in the buffer slot 22, pushing the sample to the integrated testing platform. The integrated testing platform has multiple buffer hoppers. If more samples need to be delivered (assuming there are multiple buffer slots), the second driving component 25 drives the turntable 212 to rotate relative to the fixed plate 211, so that the buffer slot 22 with the sample is switched to the sample delivery position for the next set of sample delivery. After all the buffer slots 22 have been delivered, the sample delivery will stop, and the system will prepare to run to the positioning point of the online sampling system.

[0038] The intelligent sample delivery device of this invention is applicable to flexible working conditions and does not rely on fixed pipelines and fixed equipment. It realizes a distributed layout of integrated testing station and online sampling. The integrated testing station does not need to be installed on the production line for automatic sampling, but can be installed at any location in the workshop. Only the sampling device and buffer device need to be installed on the production line. The intelligent sample delivery device completes the sample delivery between the two, which not only saves manpower, but also reduces sample damage and completes the quality control of the samples.

[0039] In some embodiments, such as Figure 1 and Figure 2 As shown, the main body 1 of the device includes a housing 11, a base plate 12, and a fixing plate 13. The housing 11 has a receiving cavity, and the fixing plate 13 is fixed within the receiving cavity. One side of the housing 11 has an opening communicating with the receiving cavity. The base plate 12 is disposed at the opening, and a rotating disk 21 is disposed on the base plate 12; that is, both the fixing disk 211 and the rotating disk 212 are disposed on the base plate 12. The first driving component 24 includes a lead screw 241, a lead screw motor 242, and a lifting plate 243. The lead screw motor 242 is disposed on the fixing plate 13, and its rotating end is connected to the lead screw 241. The lifting plate 243 is movably disposed on the lead screw 241, and the end of the lifting plate 243 away from the lead screw 241 abuts against the base plate 12.

[0040] In this embodiment, the lifting plate 243 is provided with an internal thread that is compatible with the lead screw 241. During operation, the lead screw motor 242 can drive the lead screw 241 to rotate, and the lifting plate 243 can move up and down in the receiving cavity under the rotation of the lead screw 241. Since the lifting plate 243 abuts against the base plate 12, during the up and down movement of the lifting plate 243, the turntable 212, the fixed plate 211 and the buffer slot 22 on the base plate 12 can be driven to move in the vertical direction.

[0041] To ensure that the lifting plate 243 can only move vertically, the first driving component 24 also includes a guide rod 244 and a guide sleeve 245. The guide sleeve 245 is mounted on the fixed plate 13, the first end of the guide rod 244 is connected to the lifting plate 243, and the second end of the guide rod 244 passes through the guide sleeve 245. Thus, during the process of the lead screw motor 242 driving the lead screw 241 to rotate, the lifting plate 243 can move up and down in the receiving cavity, and at the same time, the guide rod 244 also moves up and down. Under the limitation of the guide sleeve 245, the guide rod 244 ensures that the lifting plate 243 can only move vertically.

[0042] Furthermore, multiple guide rods 244 and guide sleeves 245 are provided, and multiple guide sleeves 245 are spaced apart on the fixing plate 13, with the second end of the guide rod 244 passing through the corresponding guide sleeve 245.

[0043] Specifically, the fixed plate 13 has two mounting holes for mounting guide sleeves 245, located on both sides of the lead screw motor 242. Two guide sleeves 245 are provided, each mounted in one of the two mounting holes. Correspondingly, two guide rods 244 are provided, with their second ends passing through the corresponding guide sleeves 245. The limiting effect of the two guide rods 244 and the two guide sleeves 245 further restricts the direction of movement of the lifting plate 243.

[0044] In some embodiments, such as Figure 1 and Figure 2 As shown, the second driving component 25 includes a stepper motor 252 and a moving gear 251. The stepper motor 252 is mounted on the fixed disk 211, and the rotating end of the stepper motor 252 meshes with the turntable 212 through the moving gear 251. The moving gear 251 and the turntable 212 are in gear meshing, and the rotation of the turntable 212 is achieved by the stepper motor 252 driving it to rotate, thus realizing the rotation of the buffer slot 22.

[0045] In some embodiments, such as Figure 1 and Figure 2 As shown, the third driving component 26 includes a cylinder 261, a connecting plate 262, a connecting rod 263, and a mechanical pusher 264. The cylinder 261 can be a rodless cylinder. The connecting plate 262 is mounted on the cylinder 261. The mechanical pusher 264 is connected to the connecting plate 262 via the connecting rod 263. The cylinder 261 is mounted on the fixed plate 211 and is used to drive the mechanical pusher 264 to move via the connecting plate 262. During operation, the cylinder 261 controls the movement of the connecting plate 262, and the connecting rod 263, driven by the connecting plate 262, drives the mechanical pusher 264 to move within the buffer slot 22.

[0046] Generally, the turntable 212 is rotatably mounted on the fixed disk 211. Multiple buffer slots 22 are provided, spaced apart on the turntable 212. For example, in this embodiment, four buffer slots 22 are provided, spaced apart around the turntable 212. Since the cylinder 261, connecting plate 262, connecting rod 263, and mechanical pusher 264 are all located on the fixed disk 211, the position of the third driving member 26 remains unchanged when the turntable 212 rotates relative to the fixed disk 211. Therefore, after the cylinder 261 controls the mechanical pusher 264 to complete the feeding of one buffer slot 22, the turntable 212 can be rotated to make another buffer slot 22 face the mechanical pusher 264, allowing one mechanical pusher 264 to complete the feeding of multiple buffer slots 22.

[0047] In some embodiments, such as Figure 1 and Figure 2 As shown, the intelligent sample delivery device also includes an obstacle avoidance sensor 4. The obstacle avoidance sensor 4 can be installed on the main body 1 or the motion mechanism 3, or simultaneously on the main body 1 and the motion mechanism 3. The obstacle avoidance sensor 4 is electrically connected to the motion mechanism 3.

[0048] In this embodiment, multiple obstacle avoidance sensors 4 are provided, and the multiple obstacle avoidance sensors 4 are installed around the motion mechanism 3. The obstacle avoidance sensors 4 are used to effectively avoid or stop operation when encountering obstacles.

[0049] Based on the above embodiments, in one example, the intelligent sample delivery device further includes a positioning switch 5. The positioning switch 5 is disposed on the main body 1 of the device and is located on one side of the buffer slot 22. It is electrically connected to the first driving component 24 and the second driving component 25 and is used to detect the position of the buffer slot 22 relative to the external equipment (integrated test bench and online sampling system).

[0050] During operation, the positioning switch 5 continuously monitors the position of the buffer slot 22 relative to the external device. When the buffer slot 22 is not aligned with the integrated test bench or online sampling system, the positioning switch 5 controls the first drive component 24 to adjust the height and controls the second drive component 25 to control the rotation angle. Once the buffer slot 22 is aligned with the integrated test bench or online sampling system, the positioning switch 5 controls the first drive component 24 and the second drive component 25 to close, thus ensuring that the buffer slot 22 is aligned with the integrated test bench or online sampling system.

[0051] The intelligent sample delivery device also includes a navigation sensor 6, which is mounted on the main body 1 or the motion mechanism 3. The navigation sensor 6 has infrared lidar and collision avoidance detection. The navigation sensor 6 stores a map internally, allowing the motion mechanism 3 to operate within the workshop according to the map's trajectory.

[0052] In this embodiment, the motion mechanism 3 is a motion trolley, which is responsible for driving the entire intelligent sample delivery device forward and running in the workshop according to the map trajectory. It is equipped with obstacle avoidance sensor 4 and navigation sensor 6, and a mechanical positioning lock is designed in front of the motion trolley. The mechanical positioning lock is used to accurately position the intelligent sample delivery device to the positioning point. There are three positioning points: one is the comprehensive testing platform positioning point, used for positioning during sample delivery; one is the online sampling system positioning point, used for positioning during sampling; and the other is the charging positioning point, used for positioning during charging.

[0053] In addition, to facilitate the operation of the entire intelligent sample delivery device, a power supply is built into the main body 1 or the motion mechanism 3. The power supply is electrically connected to other components to provide the power required for the operation of the entire intelligent sample delivery device.

[0054] In one specific embodiment, such as Figure 1 and Figure 2 The specific workflow is shown below:

[0055] The mobile cart is responsible for driving the entire intelligent sample delivery device forward. It uses navigation sensor 6 for positioning and runs in the workshop according to the map trajectory. It uses obstacle avoidance sensor 4 for effective obstacle avoidance. The mobile cart can go to the charging positioning point for charging. After receiving a work task, it will travel back and forth between the online sampling system and the integrated testing platform to collect and deliver samples. It will stop running after reaching any positioning point.

[0056] During sampling, the intelligent sample delivery device reaches the positioning point of the online sampling system. The moving trolley precisely positions the intelligent sample delivery device at the positioning point. The buffer slot 22 is raised and lowered by the base plate 12 below it via the positioning switch 5, aligning the buffer slot 22 with the online sampling system. After alignment, the online sampling system delivers the sample into the buffer slot 22. If further sampling is needed, the turntable 212 rotates the buffer slot 22 90°, causing the empty buffer slot 22 to switch to the sampling position for the next set of sampling. Once all four buffer slots 22 are full, sampling stops, and the device prepares to move to the positioning point of the integrated testing platform. The intelligent sample delivery device can fill one online sampling point at once, fill multiple online sampling points, or not fill them completely; it can deliver samples to the positioning point of the integrated testing platform as soon as it receives an instruction. After completing the task set by the scheduling system, the intelligent sample delivery device returns to the integrated testing platform under the guidance of the navigation system.

[0057] During sample delivery, after receiving the arrival signal from the intelligent sample delivery device, the scheduling system notifies the integrated testing platform to enter the receiving state. The scheduling system inputs the sample information to be tested into the integrated testing platform. When the intelligent sample delivery device reaches the positioning point on the integrated testing platform, the moving trolley precisely positions the intelligent sample delivery device to the positioning point. The buffer slot 22, controlled by the positioning switch 5, raises and lowers the base plate 12 below, aligning the buffer slot 22 with the integrated testing platform. After alignment, the mechanical pusher 264 delivers the sample from the buffer slot 22 into the integrated testing platform. The integrated testing platform has multiple buffer hoppers. If further sample delivery is needed, the turntable 212 rotates the buffer slot 22 90°, causing the buffer slot 22 with samples to switch to the sample delivery position for the next set of samples. Sample delivery stops after all four buffer slots 22 have been delivered. After delivery is completed, the platform awaits the next round of task assignment from the scheduling system, and the integrated testing platform can then complete the sample testing.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
