Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and more specifically, to a cap dispensing and conveying device. Background Technology

[0002] Blood tests are a crucial tool for doctors in diagnosing diseases and an essential part of routine physical examinations for the general public. Therefore, medical and health check-up services consume a large number of erythrocyte sedimentation rate (ESR) tubes annually. Currently, the assembly and production of the safety caps on vacuum ESR tubes are primarily done manually, resulting in low production efficiency and limiting output. However, in implementing the technical solution described in this application, the inventors discovered at least the following technical problems: During operation, when materials are transported to the guide channel for distribution, materials tend to accumulate at the channel entrance, requiring manual intervention and resulting in low production efficiency. Utility Model Content

[0003] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a cap-dispensing and conveying device. This application provides the following technical solution:

[0004] The first aspect of this application is to provide a cap-type material conveying device.

[0005] According to the first aspect of this application, a cap-dispensing and conveying device is proposed, comprising: a machine body, wherein the machine body is provided with a conveying guide structure and a cap support structure; a conveying guide structure, wherein the conveying guide structure is provided with a guide unit, wherein the guide unit is provided with a plurality of guide channels arranged parallel to each other along the conveying direction; and a cap support structure, wherein the cap support structure is provided with a support unit, wherein the positions of the plurality of support units correspond one-to-one with the plurality of guide channels.

[0006] In the above technical solution, the material is distributed and output through the guide channel after passing through the conveying and guiding structure. It can automatically complete the cap conveying and cap distribution of several vacuum blood sedimentation tube caps. The whole process has a high degree of automation, high production efficiency, low labor cost, and high reliability, and is suitable for large-scale production.

[0007] In some technical solutions, the conveying and guiding structure has a conveying body, a conveying belt is arranged around the conveying body, and conveying side baffles are symmetrically arranged on both sides of the conveying belt. The guiding unit is installed on the conveying side baffles. The conveying side baffles on both sides are respectively provided with a first air hole group and a second air hole group, and the two air hole groups are horizontally distributed on both sides of the inlet of the guiding unit.

[0008] For example, the conveyor belt is driven by a speed-regulating motor, which can be adjusted according to the speed of the equipment, making it convenient, fast, and highly operable.

[0009] In one specific embodiment, the conveying and guiding structure has a conveying body with a conveyor belt surrounding it. Conveying side baffles are symmetrically arranged on both sides of the conveyor belt. A guiding unit is mounted on the conveying side baffles via a crossbeam. The conveyor belt is driven by a speed-regulating motor, transporting caps entering the conveyor belt to the inlet of the guiding unit. The speed can be adjusted by changing the equipment's operating speed; if too many caps accumulate at the inlet of the guiding unit, the operating speed can be reduced. The conveying side baffles on both sides are respectively provided with a first air hole group and a second air hole group, which are horizontally distributed along both sides of the inlet of the guiding unit. The two air hole groups are mirror images of each other inside the conveying side baffles, with the air holes having an airflow inclination angle of 30 degrees away from the direction of the guiding unit inlet. The air hole groups on both sides are connected to a three-position five-way centrally sealed solenoid valve. The three-position five-way centrally sealed solenoid valve performs alternating airflow control on the two air hole groups. For example, the first air hole group on one side performs airflow for 2 seconds, then the second air hole group on the other side performs airflow for 2 seconds, with a 2-second interval, and then the airflow is alternately performed again. Controlled by a three-position five-way central sealing solenoid valve, alternating air blowing can be performed to disperse the caps that have accumulated at the entrance of the guide unit due to conveying, ensuring that the caps can smoothly enter the guide unit.

[0010] In another specific embodiment, two sets of air vents are staggered and alternately arranged inside the conveyor-side baffle. The air vents have an airflow inclination angle of 30 degrees away from the inlet direction of the guide unit. The air vents on both sides are connected to a three-position five-way centrally sealed solenoid valve. The three-position five-way centrally sealed solenoid valve controls the airflow of the two sets of air vents. The two sets of air vents staggered on both sides simultaneously perform staggered airflow to disperse the caps that have accumulated at the inlet of the guide unit due to the conveying process, ensuring that the caps smoothly enter the guide unit.

[0011] In some technical solutions, the number of guide channels in the guide unit is 10, and the guide channels are detachably connected to the conveying guide structure.

[0012] In the above technical solution, the guide channel and the conveying guide structure are detachably connected, and the guide channel can be changed according to the size of the cap.

[0013] In some technical solutions, the support unit is provided with stepped structures on both sides, and the height of the stepped structures matches the distance from the brim of the cap to the bottom.

[0014] In the above technical solution, the support unit has stepped structures on both sides. The height of the stepped structures is set according to the distance between the brim and the bottom to ensure that the cap is supported during suction and will not deform. The stepped structures on both sides of the support unit support the caps of the two adjacent channels respectively.

[0015] In some technical solutions, the cap support structure has a support body, a support base plate fixed on the support body, and a plurality of support units disposed above the support base plate; a limiting baffle is vertically disposed at the end of the support base plate and has an embedded positioning detection unit, the signal output terminal of the positioning detection unit being connected to an external controller.

[0016] In some technical solutions, the positioning detection unit is a photoelectric sensor, with its transmitting end and receiving end respectively located on both sides of the limiting baffle.

[0017] Specifically, the cap support structure has a support body with a support base plate fixed on it, and several support units are arranged above the support base plate; a limiting baffle is vertically arranged at the end of the support base plate and has an embedded positioning detection unit. The signal output end of the positioning detection unit is connected to an external controller. The positioning detection unit is a photoelectric sensor, and its transmitting end and receiving end are respectively arranged on both sides of the limiting baffle to quickly feed back the positioning status of the channel to the external controller for processing.

[0018] In some technical solutions, the conveying guide structure also includes a transparent cover plate covering the conveying guide structure, and the transparent cover plate is detachably connected to the conveying guide structure.

[0019] In some technical solutions, the conveying guide structure also includes a transparent cover plate covering the conveying guide structure. The transparent cover plate is detachably connected to the conveying guide structure. The transparent cover plate allows for clear observation of the real-time material distribution of the cap, facilitating timely handling of problems by the operator.

[0020] In some technical solutions, the surface of the supporting base plate is smoothed, with a surface roughness Ra ≤ 0.8 μm. For example, the supporting base plate is made of stainless steel.

[0021] In the above technical solution, the stainless steel support base plate is smoothed to a surface finish of 0.8, ensuring that the cap slides smoothly on the base plate.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0023] This utility model adopts the above-mentioned technical solution to automatically complete the feeding and dispensing of several vacuum blood sedimentation tube caps through a guide unit, thereby solving the problem of material accumulation in the guide and dispensing of blood sedimentation tube caps, improving the efficiency of cap dispensing and feeding, effectively reducing manual intervention, realizing full-process automation, adapting to different specifications of caps, and having strong versatility and compatibility with production lines from different manufacturers.

[0035] The following is combined Figures 1-5 The structure and operation process of this utility model will be further explained in detail through specific embodiments.

[0036] like Figure 1-5 As shown, some embodiments of this application disclose a cap-dispensing and conveying device, the structure of which includes: a machine body, wherein the machine body is provided with a conveying guide structure 1 and a cap support structure 2; the conveying guide structure 1, wherein the conveying guide structure 1 is provided with a guide unit 11, wherein the guide unit 11 is provided with a plurality of guide channels 12 arranged parallel to each other along the conveying direction; and the cap support structure 2, wherein the cap support structure 2 is provided with a support unit 21, wherein the positions of the plurality of support units 21 correspond one-to-one with the plurality of guide channels 12.

[0037] In the above embodiment, after the material passes through the conveying and guiding structure 1, it is distributed and output through the guiding channel 12. The conveying and distributing of several vacuum blood sedimentation tube caps can be completed automatically. The whole process has a high degree of automation, high production efficiency, low labor cost, and high reliability, making it suitable for large-scale production.

[0038] In some embodiments, the conveying guide structure 1 has a conveying body 13, a conveying belt 14 is arranged around the conveying body 13, and conveying side baffles 15 are symmetrically arranged on both sides of the conveying belt 14.

[0039] For example, the conveyor belt 14 is driven by a speed-regulating motor, which can be adjusted according to the speed of the equipment, making it convenient, fast, and highly operable.

[0040] In one specific embodiment, the conveying guide structure 1 has a conveying body 13, around which a conveyor belt 14 is arranged.

[0041] In another specific embodiment, two sets of air vents are staggered and alternately arranged inside the conveyor side baffle 15. The air vents have an airflow inclination angle of 30 degrees away from the inlet direction of the guide unit 11. The air vents on both sides are connected to the three-position five-way central sealing solenoid valve 4.

[0043] In the above embodiment, the guide channel 12 and the conveying guide structure 1 are detachably connected, and the guide channel 12 can be changed according to the size of the cap 3.

[0044] In some embodiments, the support unit 21 is provided with step structures 22 on both sides, and the height of the step structures 22 matches the distance from the brim to the bottom of the cap 3.

[0045] In the above embodiment, the support unit 21 is provided with step structures 22 on both sides.

[0047] In some embodiments, the positioning detection unit 26 is a photoelectric sensor, with its transmitting end and receiving end respectively disposed on both sides of the limiting baffle 25.

[0048] Specifically, the cap support structure 2 has a support body 23, on which a support base plate 24 is fixed, and a plurality of support units 21 are disposed above the support base plate 24; a limiting baffle 25 is vertically disposed at the end of the support base plate 24, and a positioning detection unit 26 is embedded therein, the signal output end of the positioning detection unit 26 is connected to an external controller, the positioning detection unit 26 is a photoelectric sensor, and its transmitting end and receiving end are respectively disposed on both sides of the limiting baffle 25, so as to quickly feed back the positioning status of the channel to the external controller for processing.

[0051] In some embodiments, the surface of the support base plate 24 is smoothed, with a surface roughness Ra ≤ 0.8 μm. For example, the support base plate 24 is made of stainless steel.

[0052] In the above embodiment, the support base plate 24 is smoothed to a surface finish of 0.8, ensuring that the cap slides smoothly on the base plate.

[0053] The working process of this utility model:

[0054] Step 1: Cap loading and initial guidance. The conveyor guide structure 1 has a conveyor body 13, around which a conveyor belt 14 is arranged. Conveyor side baffles 15 are symmetrically arranged on both sides of the conveyor belt 14. The guide unit 11 is mounted on the conveyor side baffles via a crossbeam. The conveyor belt 14 is driven by a speed-regulating motor. Vacuum-sealed blood vessel caps enter the conveyor belt 14 through the device inlet. The speed-regulating motor drives the conveyor belt 14 to transport the caps to the inlet of the guide unit 11. The conveying speed can be adjusted in real time according to the stacking situation. The caps are transported to the inlet of the guide unit 11.

[0055] The guide channel 12 at the entrance of the guide unit 11 has a gradient design with shorter sides and a longer middle section. The conveyor side baffles 15 on both sides are respectively provided with a first air hole group 16 and a second air hole group 17. The two air hole groups are horizontally distributed on both sides of the entrance of the guide unit 11. The two air hole groups are mirror images of each other inside the conveyor side baffles 15. The two air hole groups are tilted at a 30° angle away from the entrance. The first air hole group 16 and the second air hole group 17 are controlled by a three-position five-way central sealing solenoid valve 4. The two air hole groups alternately blow air away from the entrance at a 30° angle, blowing air for 2 seconds on the left side, 2 seconds on the right side, and pausing for 2 seconds. This blows the caps alternately from the two side channel entrances to the middle channel entrance, avoiding the accumulation of caps in the same guide channel 12 and distributing the caps evenly in each guide channel 12, ensuring that each cap enters the guide channel 12 individually.

[0056] Step 2: Parallel material transfer, the cap enters the guide channel 12. The guide channel 12 of the guide unit 11 is detachably mounted on the conveying side plate through the crossbeam. The guide unit 11 has 10 parallel channels. The guide channel 12 can be disassembled and replaced through the crossbeam according to the cap structure.

[0057] The guide unit 11 is detachably mounted on the conveyor side plate via a crossbeam, and the transparent cover plate 18 covers the top of the conveyor side plate, making it easy for the operator to observe the material jamming situation in the guide channel 12;

[0058] The guide channel 12 is detachably mounted on the conveyor side plate via a crossbeam, and the cap is transported to the support unit 21 along the guide channel 12 via the conveyor belt 14.

[0059] The support unit 21 has step structures 22 on both sides. The height of the step structures 22 matches the distance from the brim of the cap to the bottom. After the cap is separated from the guide channel 12, the brims on both sides of the cap are inserted into the step structures 22 of the support units 21 on both sides.

[0060] Step 3: Precise Positioning and Status Detection. The cap support structure 2 has a support body 23, on which a support base plate 24 is fixed. Several support units 21 are disposed above the support base plate 24. A limiting baffle 25 is vertically disposed at the end of the support base plate 24 and has an embedded positioning detection unit 26. The signal output terminal of the positioning detection unit 26 is connected to an external controller. The positioning detection unit 26 is a photoelectric sensor, with its transmitting and receiving ends respectively located on both sides of the limiting baffle 25. The cap slides along the smooth base plate into the support unit 21 at the end. When the cap touches the limiting baffle 25 above the support unit 21, the light from the photoelectric sensor's transmitting end is blocked, triggering a positioning signal. The signal is transmitted to the external controller to confirm that the cap is in position in the current channel.

[0061] Step 4: The controller executes subsequent actions based on the photoelectric sensor signal, triggering the robotic arm to pick up the cap for use in the assembly of the blood sedimentation tube; if a certain channel does not detect the arrival signal, an alarm will be triggered to prompt for material replenishment or to check for material jamming.
