Description

Technical Field

[0001] This utility model relates to the field of biological sample storage technology, and in particular to a machine for bulk storage of vaccines. Background Technology

[0002] In the field of vaccine cold chain storage, the biological activity of vaccines depends on maintaining a continuously low-temperature environment. Furthermore, in large-scale storage scenarios, orderly management of vaccines is essential to ensure both management order and retrieval efficiency. Based on this requirement, automated boxed vaccine storage systems have become the mainstream application equipment in this field.

[0003] Automated boxed vaccine storage systems typically consist of a cold storage facility and an automated inbound / outbound mechanism within it. These two components work together to provide core equipment support for large-scale vaccine storage and are a key part of the current vaccine cold chain storage system. In the actual execution of vaccine warehousing operations, the mainstream operation method of existing automated inbound / outbound mechanisms is single-box sorting by robotic arms. Specifically, the robotic arm can only grab and transfer one vaccine box at a time, moving it to the corresponding storage location inside the cold storage facility.

[0004] While the single-box sorting design can meet the basic functional requirements of automated warehousing, it has obvious limitations in the scenario of large-scale warehousing when vaccines arrive in bulk: due to the limited processing capacity of the robotic arm at one time, the overall warehousing efficiency is significantly low, which cannot adapt to the demand for simultaneous warehousing of large batches of vaccines. This directly restricts the throughput of the automated boxed vaccine storage system and makes it difficult to meet the needs of large-scale operation in the field of vaccine storage.

[0005] In summary, technical personnel are urgently needed to solve the above problems. Utility Model Content The purpose of this invention is to provide a vaccine bulk warehousing machine, which aims to solve the problems of low sorting efficiency, poor connection between conveying and pushing, and difficulty in accurately transferring large quantities of vaccines to the cold storage robotic arm in the existing technology.

[0006] This utility model relates to a vaccine bulk warehousing machine, characterized in that it includes a conveyor, an upstream blocking mechanism, a downstream blocking mechanism, a straightening mechanism, and a pushing mechanism; The conveyor is used to carry and transport boxed vaccines to be stored, and to realize the batch temporary storage and continuous transport of boxed vaccines; The upstream blocking mechanism is located at the feed end of the conveyor; when the vaccine is put into storage, the upstream blocking mechanism blocks the feed end and serves as the placement benchmark for the boxed vaccines; after a single batch of boxed vaccines has been placed, the upstream blocking mechanism changes its posture to release the blockage. The downstream blocking mechanism is located at the discharge end of the conveyor, while the straightening mechanism is located downstream of the downstream blocking mechanism. During operation, after the conveyor delivers the boxed vaccine to the discharge end, the downstream blocking mechanism first blocks the boxed vaccine to form a stopping reference, and then changes its posture to release the blockage, allowing the boxed vaccine to move horizontally toward the straightening mechanism. After the boxed vaccine reaches the working position of the straightening mechanism, the downstream blocking mechanism changes its posture again to stop the subsequent boxed vaccines. At the same time, the straightening mechanism performs a horizontal pushing operation according to the width of the boxed vaccine, cooperating with the downstream blocking mechanism to straighten the boxed vaccine. The pushing mechanism is set up to correspond to the position of the boxed vaccine after positioning and alignment, and works in conjunction with the alignment mechanism and the downstream blocking mechanism to form a pushing operation area; after the boxed vaccine is positioned and aligned, the pushing mechanism pushes it in the direction of the boxed vaccine, pushing it in batches to the robotic arm in the vaccine cold storage.

[0007] As a further improvement to the technical solution disclosed in this utility model, the upstream blocking mechanism includes an upstream gantry frame, an upstream blocking component, an upstream lifting power unit, and an upstream lifting guide assembly; the upstream gantry frame spans both sides of the feed end of the conveyor and is fixed to the conveyor as a whole; the upstream gantry frame serves as a common mounting base for the upstream lifting power unit and the upstream lifting guide assembly; the upstream blocking component is slidably assembled on the upstream lifting guide assembly; the upstream lifting power unit is used to drive the upstream blocking component to perform lifting motion, and its output end is connected to the upstream blocking component; when the upstream blocking component descends and fits against the conveying surface of the conveyor, it forms a placement reference for the boxed vaccine; and when the upstream blocking component rises and separates from the conveying surface of the conveyor, it releases the blockage on the feed end.

[0008] As a further improvement to the technical solution disclosed in this utility model, the upstream material blocking mechanism also includes a barcode scanner; the barcode scanner is used to scan and identify vaccine information during the placement of boxed vaccines, and it is installed on the upstream gantry frame and is arranged directly opposite the conveying area at the inlet end.

[0009] As a further improvement to the technical solution disclosed in this utility model, the upstream material blocking mechanism also includes a distance measuring sensor; the distance measuring sensor is used to detect the single batch placement width of the boxed vaccines, with the upstream gantry as the installation base, and the detection end facing the feed end conveying surface of the conveyor.

[0010] As a further improvement to the technical solution disclosed in this utility model, the downstream blocking mechanism includes a downstream gantry frame, a downstream blocking component, a downstream lifting power unit, and a downstream lifting guide assembly; the downstream gantry frame spans both sides of the conveyor's discharge end and is fixed to the conveyor as a whole; the downstream gantry frame serves as a shared mounting base for the downstream lifting power unit and the downstream lifting guide assembly; the downstream blocking component is slidably mounted on the downstream lifting guide assembly; the downstream lifting power unit is used to drive the downstream blocking component to perform lifting motion, and its output end is connected to the downstream blocking component; when the downstream blocking component descends and fits against the conveying surface of the conveyor, it forms a stopping reference for the boxed vaccine; and when the downstream blocking component rises and separates from the conveying surface of the conveyor, it releases the blockage on the discharge end.

[0011] As a further improvement of the technical solution disclosed in this utility model, the pushing mechanism includes a pushing component and a pushing power unit; the pushing component is located on the side of the downstream blocking component facing the alignment mechanism; the pushing power unit is fixed on the downstream gantry frame, and its output end is connected to the pushing component; the pushing surface of the pushing component is adapted to the end face of the boxed vaccine after positioning and alignment, and the pushing direction is towards the robotic arm inside the vaccine cold storage.

[0012] As a further improvement to the technical solution disclosed in this utility model, the pushing power unit is composed of a primary synchronous belt drive mechanism and a secondary synchronous belt drive mechanism; the fixed end of the primary synchronous belt drive mechanism is installed on the downstream gantry, and its output end is connected to the fixed end of the secondary synchronous belt drive mechanism; the output end of the secondary synchronous belt drive mechanism is connected to the pushing component; during operation, the primary synchronous belt drive mechanism drives the secondary synchronous belt drive mechanism to move as a whole, and at the same time, the secondary synchronous belt drive mechanism drives the pushing component to push the boxed vaccine.

[0013] As a further improvement to the technical solution disclosed in this utility model, the correction mechanism includes a support frame, a correction actuator, a correction power unit, and a correction guide assembly; the support frame is fixed downstream of the discharge end of the conveyor and spans the conveyor, serving as a shared mounting carrier for the correction power unit and the correction guide assembly; the correction actuator is slidably mounted on the correction guide assembly, with its pushing surface facing the side wall of the boxed vaccine; the correction power unit is used to drive the correction actuator to perform translational motion, and its output end is connected to the correction actuator.

[0014] In practical applications, the vaccine bulk warehousing machinery disclosed in this utility model can achieve at least the following beneficial technical effects, specifically: 1) The conveyor can realize the batch temporary storage and continuous transportation of boxed vaccines; the upstream blocking mechanism can accurately control the placement and transportation rhythm of a single batch of vaccines through the action of blocking and unblocking. The downstream blocking mechanism and the alignment mechanism work together to complete the stopping, translation and posture alignment of the vaccines. Finally, the pushing mechanism pushes the aligned multiple boxes of vaccines in batches to the robotic arm in the cold storage. This changes the traditional design where the robotic arm can only handle a single box of vaccines at a time. It effectively adapts to the large-scale warehousing scenario of centralized vaccine delivery and greatly improves the throughput of the automated boxed vaccine storage system. 2) The coordinated operation of the conveyor, upstream blocking mechanism, downstream blocking mechanism, alignment mechanism and pushing mechanism can realize the batch pre-processing and orderly transportation of vaccines outside the cold storage. This helps to reduce the frequency of personnel entering the cold storage to replenish vaccines, reduce the risk of personnel being exposed to the low temperature environment, and avoid the loss of cold storage and temperature fluctuations caused by frequent personnel entry and exit. Furthermore, the upstream blocking mechanism, downstream blocking mechanism, alignment mechanism and pushing mechanism all form a compact coordinated operation system around the conveyor, making the overall design structure more compact. This improves the utilization rate of cold storage capacity and is more in line with the usage needs of small and medium-sized cold storage or space-constrained storage scenarios.

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to specific embodiments. Figure 1 , Figure 2 The diagrams show two different perspectives of the vaccine batch warehousing machine disclosed in this utility model. It can be seen that it mainly consists of a belt conveyor 1, an upstream blocking mechanism 2, a downstream blocking mechanism 3, a straightening mechanism 4, and a pushing mechanism 5. The conveyor 1 is the core transport carrier for boxed vaccines. The upstream blocking mechanism 2 and the downstream blocking mechanism 3 are arranged corresponding to the inlet and outlet ends of the conveyor 1, respectively. The straightening mechanism 4 is located downstream of the downstream blocking mechanism 3, and the pushing mechanism 5 adapts to the straightened vaccine position, working together to realize the vaccine batch warehousing process.

[0027] The conveyor belt of belt conveyor 1 is made of food-grade PU material with an anti-slip textured surface, which enhances friction with the bottom of the boxed vaccines and meets the hygiene requirements for boxed vaccine storage. The belt width is designed based on the maximum placement width of a single batch of vaccines, ensuring that batches of vaccines can be transported side by side smoothly. Belt conveyor 1 uses soft start / soft stop control to prevent vaccines from tipping over due to inertial impact.

[0028] like Figure 3 , Figure 4 As shown, the upstream material blocking mechanism 2 mainly consists of several parts, including an upstream gantry frame 21, an upstream material blocking component 22, an upstream through-type screw motor 23, and an upstream lifting guide assembly 24. The upstream gantry frame 21 spans the front and rear sides of the feed end of the belt conveyor 1 and is fixed to the belt conveyor 1 as a whole by high-strength bolts, serving as a shared mounting base for the upstream through-type screw motor 23 and the upstream lifting guide assembly 24. The upstream lifting guide assembly 24 is composed of an upstream front slide rail slider assembly 241 and an upstream rear slide rail slider assembly 242. Both the upstream front slide rail slider assembly 241 and the upstream rear slide rail slider assembly 242 are fixed to the right side wall of the upstream gantry frame 21, parallel to each other, and extend along the height direction. They work together to ensure that the upstream material blocking component 22 does not deviate or jam during lifting and is accurately guided. When the downstream baffle 22 descends and comes into contact with the surface of the conveyor belt of the belt conveyor 1, a vaccine placement reference is formed; when the downstream baffle 22 rises and completely moves away from the expected height of the conveyor belt surface, the blockage to the feed end is released.

[0029] It is worth noting that, similarly Figure 3 , Figure 4 As shown, the upstream material blocking mechanism 2 is also equipped with a barcode scanner 25 and a distance sensor 26. The barcode scanner 25 is fixed on the left side wall of the upstream gantry 21, and the scanning angle can be finely adjusted within a range of ±15° to ensure accurate identification of the QR code / barcode on the top or side of the vaccine box, enabling real-time input of information such as vaccine batch and expiration date. The distance sensor 26 adopts the laser distance measurement principle and is installed on the right side wall of the upstream gantry 21, with the detection end facing the surface of the conveyor belt vertically. It can detect the placement width of a single batch of boxed vaccines on the conveyor belt in real time. When the width exceeds the adaptation range of the feed end of the belt conveyor 1 (e.g., exceeding 80cm), the audible and visual warning device is automatically triggered to remind the operator to adjust the placement of the boxed vaccines.

[0030] like Figure 5 , Figure 6 As shown, the downstream material blocking mechanism 3 mainly consists of a downstream gantry frame 31 and a downstream material blocking component 32 (such as...). Figure 7The downstream gantry 31 consists of several parts, including the downstream through-type screw motor 33 and the downstream lifting guide assembly 34. The downstream gantry 31 spans both sides of the discharge end of the belt conveyor 1 and is bolted to the frame of the belt conveyor 1. The downstream lifting guide assembly 34 is composed of a downstream front slide rail slider assembly 341 and a downstream rear slide rail slider assembly 342. The downstream front slide rail slider assembly 341 and the downstream rear slide rail slider assembly 342 are fixed side-by-side on the left side wall of the downstream gantry 31 and extend along the height direction. The downstream stop 32 is slidably assembled with both the downstream front slide rail slider assembly 341 and the downstream rear slide rail slider assembly 342 to prevent displacement and stop failure due to long-term use. When the downstream baffle 32 descends and comes into contact with the surface of the conveyor belt of the belt conveyor 1, a vaccine stopping reference is formed; when the downstream baffle 32 rises and is at a set distance from the surface of the conveyor belt of the belt conveyor 1, the discharge end is unblocked, allowing the vaccine to move along the conveyor belt toward the alignment mechanism 4.

[0031] like Figure 9 As shown, the correction mechanism 4 consists of a support frame 41, a correction actuator 42, a correction through-type lead screw motor 43, and a correction guide assembly 44. The support frame 41 is welded from carbon steel and is fixed to the downstream end of the discharge end of the belt conveyor 1 by bolts, spanning across the belt conveyor 1. The correction guide assembly 44 is composed of a correction front slide rail slider assembly 441 and a correction rear slide rail slider assembly 442. Both the correction front slide rail slider assembly 441 and the correction rear slide rail slider assembly 442 are detachably fixed to the top wall of the support frame 41 and extend in the left-right direction. The correction actuator 42 is slidably assembled with both the correction front slide rail slider assembly 441 and the correction rear slide rail slider assembly 442 to effectively avoid deviations in vaccine posture regularity caused by guide offset during the correction process, ensuring the consistency of vaccine position after correction. The straightening through-type lead screw motor 43 is horizontally installed in the middle of the top wall of the support frame 41 and is arranged parallel to the straightening guide assembly 44. Its output end is connected to the straightening actuator 42.

[0032] It should be noted that, compared to traditional split-type lead screw motors, the upstream through-type lead screw motor 23, the downstream through-type lead screw motor 33, and the straightening through-type lead screw motor 43 all offer higher transmission precision and have no additional transmission backlash. The straightening through-type lead screw motor 43 enables precise control of the translational stroke of the straightening actuator 42. Combined with the stable guidance of the straightening guide assembly 44, it can quickly adjust the straightening thrust and stroke according to the actual width of the packaged vaccine, ensuring the vaccine is properly aligned while preventing damage to the vaccine packaging due to excessive thrust.

[0033] Similarly, Figure 5 , Figure 6 As shown, the pushing mechanism 5 mainly consists of a pushing component 51 (such as...) Figure 8 The pusher 51 (shown in the diagram) is composed of the pusher power unit 52. The pusher 51 is located on the side of the downstream stop 32 facing the straightening mechanism 4, and its pusher surface is fully adapted to the straightened vaccine end face to ensure uniform force on the vaccine during push. The pusher power unit 52 is composed of a primary synchronous belt drive mechanism 521 and a secondary synchronous belt drive mechanism 522. The fixed end of the primary synchronous belt drive mechanism 521 is installed on the right side wall of the crossbeam of the downstream gantry 31, and its output end is connected to the fixed end of the secondary synchronous belt drive mechanism 522; the output end of the secondary synchronous belt drive mechanism 522 is connected to the pusher 51. During operation, the primary synchronous belt drive mechanism 521 drives the secondary synchronous belt drive mechanism 522 to move horizontally in the front-back direction. At the same time, the secondary synchronous belt drive mechanism 522 drives the pusher 51 to move horizontally in the same direction. By superimposing the two strokes, the pusher 51 achieves "double stroke", ensuring that the vaccine is accurately pushed to the receiving area of ​​the cold storage robotic arm.

[0034] In addition, the pushing surface of the correcting actuator 42 and the pushing surface of the pushing actuator 51 are both equipped with a buffer layer. This can not only prevent damage to the vaccine box during pushing, but also reduce frictional resistance, ensuring that the vaccine is stable in posture during the correcting and pushing process, without the risk of tipping over or displacement.

[0035] During operation, the upstream baffle 22 is driven to descend by the upstream through-type screw motor 23, precisely blocking the feed end of the belt conveyor 1 and providing a stable vaccine placement benchmark for the operator. The operator neatly places the single batch of boxed vaccines on the feed end conveyor belt. At this time, the barcode scanner 25 is activated simultaneously to scan the QR code / barcode of each box of vaccines in real time and upload information such as vaccine batch and expiration date to the control system. At the same time, the distance sensor 26 detects the single batch placement width of the vaccines on the conveyor belt to ensure that the placement specifications meet the requirements of subsequent transportation and alignment.

[0036] After a batch of vaccines has been placed and the barcode information has been scanned and confirmed to be correct, the upstream through-type screw motor 23 drives the upstream baffle 22 to rise, releasing the blockage at the inlet end; the belt conveyor 1 starts at a preset speed, smoothly conveying the boxed vaccines to the outlet end. When the vaccine reaches the outlet end, the downstream baffle 32 descends synchronously under the drive of the downstream through-type screw motor 33, blocking the vaccine from moving forward and forming a stopping reference; after the first batch of boxed vaccines comes into contact with the downstream baffle 32 and its posture is stable, the downstream through-type screw motor 33 drives the downstream baffle 32 to rise, and the vaccine continues to move horizontally towards the alignment mechanism 4 with the conveyor belt.

[0037] Once the vaccine has fully entered the working area of ​​the alignment mechanism 4, the downstream baffle 32 descends again, effectively preventing subsequent batches of vaccines (if any) from entering the working area. Subsequently, the alignment through-type screw motor 43 starts, driving the alignment actuator 42 to move smoothly towards the vaccine, forming a coordinated clamping effect with the downstream baffle 32 to precisely clamp and align the vaccine, ensuring that the posture and position of a single batch of vaccines are consistent.

[0038] After the alignment operation is completed, the primary synchronous belt drive mechanism 521 and the secondary synchronous belt drive mechanism 522 are activated. Through the coordinated transmission of the two stages, the pusher 51 is moved horizontally towards the vaccine direction, and the batch of aligned vaccines is pushed smoothly to the receiving platform of the robotic arm in the cold storage. After the pushing action is completed, the pusher 51 is reset, the downstream baffle 32 is raised, and the belt conveyor 1 transports the next batch of vaccines, thus completing the single batch warehousing operation cycle.

[0039] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
