Description

Technical Field

[0001] This invention relates to the field of infusion bottle loading technology, specifically to an automatic bottle loading device and method for a drawer-type tray. Background Technology

[0002] Intravenous infusion is one of the most widely used and important treatment methods in clinical practice. Intravenous administration is generally performed intravenously, requiring extremely high sterility. The sterility of intravenous medications is mostly achieved through terminal sterilization using a water bath sterilizer. Besides the performance of the sterilizer, the loading method of the intravenous medications is particularly important for ensuring sterility. Currently, most intravenous medication manufacturers use two loading methods. One method involves placing the medication into sterile trays, which are stacked layer by layer. The stacked trays are automatically moved in and out of the water bath sterilizer via a programmed automatic track. This method produces large trays (commonly known as large trays) and is mostly suitable for production lines of intravenous medications with a single specification and packaging form. Another method involves placing the medicine into sterilization trays, then pushing the trays layer by layer into a drawer-type sterilization cart, and finally moving the cart through a track into and out of the water bath sterilizer. The sterilization trays in this method are smaller than those in stacked sterilization trays (commonly known as small trays), and are more suitable for production lines that produce a variety of specifications, have complex sterilization processes, and various packaging forms, and where infusion medicines need to be changed frequently.

[0003] Chinese patent application “Automatic Bag Loading Equipment for Stand-Up Bags”, application number: CN201711174167.X, has solved the fully automated process technology of loading, stacking and disassembling infusion medicines in a water bath sterilizer with automatic rails and automatic inlet / outlet.

[0004] In production models that use a sterilization tray-pull-into-drawer sterilization cart, the sterilization trays are still mostly removed manually from the drawer-type sterilization cart. Then, the infusion medicines are loaded into the sterilization trays manually or semi-manually and semi-mechanically. Finally, the sterilization trays loaded with infusion medicines are pushed into the drawer-type sterilization cart manually. This process is extremely labor-intensive and inefficient.

[0005] The information disclosed in Chinese patent application "A plastic bottle or stand-up pouch conveying system with bottle handling function", application number: 201120337497.8, shows that this patent only solves the problem of plastic bottle reversal conveying, and does not involve the automatic retrieval of sterilization trays, the transfer and positioning of sterilization trays, or the method of loading sterilization trays loaded with infusion medicines into a drawer-type sterilization cart. The information disclosed in Chinese patent application "Semi-automatic sterilization bottle loading and unloading device", application number: 201420665774.1, shows a "semi-automatic sterilization bottle loading and unloading device", which has a simple structure, requires manual operation, reduces the intensity of manual labor to a certain extent, and improves production efficiency, but still does not involve the method of automatic retrieval of sterilization trays, the transfer and positioning of sterilization trays, or the method of loading sterilization trays loaded with infusion medicines into a drawer-type sterilization cart. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention aims to provide an automatic bottle loading device and method for drawer-type trays.

Using this solution, sterilization trays of different heights within the drawer-type sterilization cart can be automatically removed. After removal, the trays are automatically adjusted to the same height as the first transfer component and the empty tray reversing unit. The trays are then automatically transferred to the infusion drug loading station after a 90-degree turn.

Detailed Implementation

[0052] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0053] Example 1: This Example 1 provides an empty sterilization tray transfer mechanism, such as... Figures 1-5 As shown, a first lifting assembly 4 is disposed on one side of the sterilization cart track 10. The first lifting assembly 4 includes:

[0054] First support frame;

[0055] The first transfer component 5 is slidably connected to the first support frame; the upper surface of the first transfer component 5 has a first conveying device that is horizontally arranged from one side of the first lifting assembly 4 to the other side.

[0056] The first lifting component 17 is fixed on the first support frame and is used to drive the first transfer component 5 to slide along the height direction of the first support frame.

[0057] Take out component 3, which is disposed on the first transfer component 5. The take out component 3 can extend or retract toward the first lifting assembly 4 and transfer the sterilization tray box 2 on the drawer-type sterilization cart 1 to the first conveying device.

[0058] Compared to existing technologies that use a production mode where sterilization trays 2 are pushed into a drawer-type sterilization cart 1, most still require manual removal of the sterilization trays 2 from the drawer-type sterilization cart 1, followed by manual or semi-manual / semi-mechanical loading of infusion drugs into the sterilization trays 2, and then manual pushing of the loaded sterilization trays 2 back into the drawer-type sterilization cart 1. This process is labor-intensive and inefficient. This invention provides an empty sterilization tray 2 transfer mechanism, specifically for the flexible and plastic packaging industry, and is particularly suitable for the large-volume infusion pharmaceutical industry that uses a drawer-type sterilization cart 1 to transfer drugs into and out of the water bath sterilizer via a track. Using this solution, the sterilization trays 2 can be automatically removed from the drawer-type sterilization cart 1, improving loading efficiency. In the specific scheme, the drawer-type sterilization cart 1 is filled with empty sterilization trays 2 and located on the side of the first lifting assembly 4 of the empty sterilization trays 2. The drawer-type sterilization cart 1 is positioned by the first track locator 11 of the sterilization cart to ensure that the empty sterilization trays 2 in the drawer-type sterilization cart 1 are aligned with the sterilization tray 2 removal component 3. Then, the first lifting component 17 on the first support frame is activated, which drives the first transfer component 5 to rise and fall, so that the first conveying device on the first transfer component 5 is aligned with the empty sterilization trays 2 that need to be pulled out. After alignment, the removal component 3 is controlled to extend into the drawer-type sterilization cart 1, thereby pulling the corresponding empty sterilization trays 2 back to the first conveying device, completing the removal and transfer of a single empty sterilization tray 2.

[0059] In this embodiment, to facilitate delivery to subsequent processing steps, a second conveying device 21 is also provided on the other side of the first lifting assembly 4. The second conveying device 21 and the first conveying device have the same conveying direction, and the lifting of the first transfer component 5 can achieve the alignment of the first conveying device and the second conveying device 21. The first conveying device is used to convey its own sterilization tray 2 to the second conveying device 21. In this solution, after the empty sterilization tray 2 is taken out, it can be controlled to descend by the first lifting component 17 to align the first conveying device and the second conveying device 21. At this time, the first conveying device and the second conveying device 21 are started to convey in the same direction, so that the empty sterilization tray 2 can be delivered to the second conveying device 21 and sent to the subsequent bottle-grabbing mechanism to grab several medicines into the empty sterilization tray 2.

[0060] In this embodiment, as a specific implementation of the taking-out component 3, the taking-out component 3 includes a first bracket spanning above the first conveying device. The first bracket is provided with a box-taking pneumatic component 39. The output end of the box-taking pneumatic component 39 is equipped with a pawl component 40, which is used to drive the pawl component 40 to extend or retract toward the first lifting assembly 4.

[0061] The pawl assembly 40 includes a rod with a plurality of pawls 45 along its length. The upper end of each pawl 45 is rotatably connected to the rod, and the lower end of each pawl 45 extends downward and beyond the rod. Each pawl 45 is rotatable in a direction away from the sterilization cart track 10, and the rod has a limiting member for restricting the rotation of the pawl 45 toward the sterilization cart track 10. In this design, a first bracket spanning above the first conveying device allows the entire pneumatic assembly 39 for picking up the tray to be mounted above the first conveying device, facilitating the direct pulling of the empty sterilization tray 2 onto the lower first conveying device. The output end of the pneumatic assembly 39 includes a pawl assembly 40, preferably a telescopic cylinder, which controls the extension or retraction of the pawl assembly 40. The pawl assembly 40 includes a rod and several pawls 45 distributed on the rod. Under normal conditions, the pawls 45 hang freely under their own weight and extend downwards from the rod. During the extension of the rod, the front of the pawl 45 touches the edge of the sterilization tray 2. 45 rotates in the opposite direction. When pawl 45 enters the sterilization tray 2, it hangs freely under its own weight. Then, the control rod retracts. During the retraction process, since pawl 45 is located inside the sterilization tray 2 and has a limiting component to restrict rotation, the rear side of pawl 45 touches the inner edge of the sterilization tray 2, thus pulling it back a certain distance towards the first conveying device. Preferably, there are three pawls 45. Under the control of the electronic control system 12, the pneumatic assembly 39 extends and retracts three times to pull all the empty sterilization trays 2 back onto the first conveying device. In the above scheme, the limiting component can be equipped with a stop or similar device on the front side of the hinge end of pawl 45.

[0062] In this embodiment, to improve the stability of pulling out the empty sterilization tray 2, the pawl assembly 40 further includes a transverse connecting rod. The output end of the tray-retrieving pneumatic assembly 39 is connected to the middle of the transverse connecting rod. Both sides of the transverse connecting rod have rods, and the transverse connecting rod is perpendicular to the driving direction of the tray-retrieving pneumatic assembly 39. In this solution, the transverse connecting rod facilitates the installation of several parallel rods, each rod having several pawls 45. Therefore, by having several parallel rods act simultaneously, the empty sterilization tray can be prevented from shifting during the pulling-out process.

[0063] In this embodiment, in order to guide the extension and retraction paths, the first bracket is also equipped with a plurality of pawl guide rods 44 parallel to the rod, and the transverse connecting rod is also equipped with a plurality of sliding sleeves that are slidably connected to the pawl guide rods 44.

[0064] In this embodiment, as a specific implementation of the first lifting component 17, the first lifting component 17 includes a first lifting reducer 30 disposed on the top of the first support frame. First lifting sprockets 28 are fitted onto first lifting transmission shafts 29 on both sides of the first lifting reducer 30. A driven wheel is located at the bottom of the first support frame. First lifting chains 32 are disposed on the first lifting sprockets 28 and the driven wheel. The first transfer component 5 is connected to two of the first lifting chains 32 on both sides. In this solution, the first lifting reducer 30 is located at the top center of the first support frame, with first lifting transmission shafts 29 on both sides, thereby driving the two first lifting sprockets 28 to rotate. A driven wheel is located directly below the first lifting sprockets 28, and a first lifting chain 32 is fitted onto it, thereby controlling the transmission of the first lifting chain 32. The lifting and lowering of the first transfer component 5 is achieved through the first lifting chain 32.

[0065] In this embodiment, in order to achieve guidance in the lifting direction, the first support frame is also equipped with a plurality of first lifting guide shafts 33, and the first transfer component 5 and the first lifting guide shafts 33 are slidably connected; wherein, the first transfer component 5 can be slidably connected to the first lifting guide shafts 33 through a first linear bearing.

[0066] In this embodiment, as a specific implementation of the first conveying device, the first transfer component 5 includes a first support plate, and both sides of the first support plate are provided with a first conveying multi-row chain 43 that moves synchronously. The first support plate is also provided with a second conveying transmission reducer 42 for driving the first conveying multi-row chain 43 to run.

[0067] In this embodiment, to facilitate the detection of the position of the sterilization tray 2, the first support plate is also provided with a first detection switch 37 for detecting whether the sterilization tray 2 has entered the first conveying device, and a second detection switch 38 for detecting whether the sterilization tray 2 has completely entered the first conveying device.

[0068] In this embodiment, to facilitate the positioning of the sterilization tray 2, the first support plate is also equipped with a control positioning device 36. The control positioning device 36 is used to block or release the sterilization tray 2 on the first conveying multi-row chain 43. In this solution, after all the sterilization trays 2 have entered the first conveying device, the control positioning device 36 positions and blocks the sterilization trays 2. Subsequently, the electronic control system 12 can control the control positioning device 36 to close, thereby transferring the sterilization trays 2 from the first conveying device to the second conveying device 21.

[0069] Example 2: This Example 2 provides a sterilization tray reversing mechanism, such as... Figure 1 , Figure 6 , Figure 7As shown, it includes an empty box reversing unit 64 and a full box reversing unit 65, both located on the same side of the sterilization vehicle track 10 and arranged sequentially along the length of the sterilization vehicle track 10.

[0070] A first transverse conveying device 23 is connected between the empty box reversing unit 64 and the full box reversing unit 65;

[0071] The empty box reversing unit 64 includes two mutually perpendicular and connected second conveying devices 21 and a second transverse conveying device 24. The second conveying device 21 is perpendicular to the sterilization cart track 10 and is used to receive the sterilization tray box 2 on the drawer-type sterilization cart 1.

[0072] The full box reversing unit 65 includes two mutually perpendicular fourth conveying devices 22 and a third transverse conveying device 25. The fourth conveying devices 22 are perpendicular to the sterilization cart track 10 and are used to transport the sterilization tray 2 into the conveying drawer-type sterilization cart 1.

[0073] The second conveying device 21, the second transverse conveying device 24, the first transverse conveying device 23, the third transverse conveying device 25 and the fourth conveying device 22 are connected in sequence.

[0074] Compared to existing technologies that use a production mode where sterilization trays 2 are pushed into a drawer-type sterilization cart 1, most still involve manual removal of the sterilization trays 2 from the drawer-type sterilization cart 1, followed by manual or semi-manual / semi-mechanical loading of infusion drugs into the sterilization trays 2, and then manual pushing of the loaded sterilization trays 2 back into the drawer-type sterilization cart 1. This process is labor-intensive and inefficient. This invention provides a reversing mechanism for sterilization trays 2, particularly relevant to the flexible and plastic packaging industry. It is especially suitable for the large-volume infusion pharmaceutical industry that uses a drawer-type sterilization cart 1 to transport drugs in and out of a water bath sterilizer via a track. With this solution, sterilization trays 2 can be output from and input into the drawer-type sterilization cart 1 at the same position on the same side of the sterilization cart track 10. During the input and output process, the orientation of the sterilization trays 2 can be kept unchanged through continuous vertical and horizontal conveying, thereby achieving reversing. In the specific design, a drawer-type sterilization cart 1 is transported on the sterilization cart track 10. The empty box reversing unit 64 includes a second conveying device 21 and a second transverse conveying device 24. The drawer-type sterilization cart 1 first conveys the empty sterilization tray 2 to the second conveying device 21. Then, the sterilization tray 2 enters the second transverse conveying device 24 through the second conveying device 21, and is then conveyed to the first transverse conveying device 23. The first transverse conveying device 23 is equipped with a bottle gripping mechanism assembly 6, which can grip a number of medicines. The full sterilization tray 2 is then conveyed by the first transverse conveyor 23 to the third transverse conveyor 25, and then to the fourth conveyor 22, where it is transported into the drawer-type sterilization cart 1. Through the above-mentioned sequential conveying directions, the orientation of the sterilization tray 2 can be kept unchanged. That is, at the unloading and loading points distributed vertically on the same side of the sterilization cart track 10, the orientation of the sterilization tray 2 can be kept unchanged, thereby facilitating the unidirectional removal and insertion of the sterilization tray 2.

[0075] In this embodiment, as a specific implementation of continuous conveying while maintaining the direction of the empty sterilization tray 2, the empty tray reversing unit 64 further includes a third lifting component. The second conveying device 21 is hollow inside; the second transverse conveying device 24 is located at the hollow position of the second conveying device 21. The third lifting component is used to drive the second conveying device 21 to rise and fall, and the rising and falling of the second conveying device 21 is used to convey the sterilization tray 2 onto the second transverse conveying device 24. In this scheme, after the sterilization tray 2 enters the second conveying device 21, its specific position is detected by the fourth detection device. The sterilization tray 2 is located directly above the second transverse conveying device 24. Then, the third lifting component is activated to control the second conveying device 21 to descend, so that the sterilization tray 2 lands on the second transverse conveying device 24. At this time, the second transverse conveying device 24 is activated, which can transport the sterilization tray 2 to the first transverse conveying device 23 while maintaining the direction of the sterilization tray 2 unchanged.

[0076] In this embodiment, as a specific implementation of lifting, the third lifting component includes a first horizontal frame, which is fixedly connected to the lower part of the second horizontal conveying device 24. A plurality of first driving lifting cylinders 57 are evenly distributed on both sides of the first horizontal frame. The output ends of the plurality of first driving lifting cylinders 57 are respectively connected to both sides of the second conveying device 21 and are used to drive the second conveying device 21 to lift.

[0077] In this embodiment, to facilitate guidance in the lifting direction, a plurality of first guide cylinders are provided between the first crossbeam and the second conveying device 21.

[0078] In this embodiment, in order to facilitate the transport of the sterilization tray 2 to the designated position, the second conveying device 21 is also provided with a first damper 60. The first damper 60 adopts a flexible stop and is used to block the sterilization tray 2 from moving forward in the second conveying device 21.

[0079] In this embodiment, as a specific implementation of continuous conveying while maintaining the direction of the full sterilization tray 2, the full tray reversing unit 65 further includes a fourth lifting component. The fourth conveying device 22 is hollow inside. The third transverse conveying device 25 is located at the hollow position of the fourth conveying device 22. The fourth lifting component is used to drive the fourth conveying device 22 to rise and fall, and the rising and falling of the fourth conveying device 22 is used to convey the sterilization tray 2 on the third transverse conveying device 25 to its own position. In this scheme, initially, the fourth conveying device 22 is located below the third transverse conveying device 25. When the first transverse conveying device 23 conveys the full sterilization tray 2 to the third transverse conveying device 25 and its specific position is detected by the fifth detection device, the fourth lifting component is controlled to drive the fourth conveying device 22 to rise, so that the full sterilization tray 2 can be conveyed onto the fourth conveying device 22. Subsequently, the full sterilization tray 2 is conveyed into the drawer-type sterilization cart 1 through the fourth conveying device 22.

[0080] In this embodiment, as a specific implementation of lifting, the fourth lifting component includes a second horizontal frame, which is fixedly connected to the lower part of the third horizontal conveying device 25. A plurality of second driving lifting cylinders 70 are evenly distributed on both sides of the second horizontal frame. The output ends of the plurality of second driving lifting cylinders 70 are respectively connected to both sides of the fourth conveying device 22 and are used to drive the fourth conveying device 22 to lift.

[0081] In this embodiment, to facilitate guidance in the lifting direction, a number of first guide cylinders are also provided between the second crossbeam and the fourth conveying device 22.

[0082] In this embodiment, to facilitate the transport of the sterilization tray 2 to the designated position, a plurality of second dampers 67 are evenly distributed on the outer side of the fourth conveying device 22. The second dampers 67 are flexible blocks and are used to block the advance of the sterilization tray on the third transverse conveying device 25. The height of the second dampers 67 is always higher than that of the third transverse conveying device 25.

[0083] In this embodiment, the second conveying device 21, the second transverse conveying device 24, the first transverse conveying device 23, the third transverse conveying device 25 and the fourth conveying device 22 each include conveying chains disposed on both sides, and baffles disposed on the outside of the conveying chains.

[0084] Example 3: This Example 3 provides a mechanism for transferring a full sterilization tray, such as... Figure 1 , Figures 8-11 As shown, a second lifting assembly 9 is provided on one side of the sterilization cart track 10, and the second lifting assembly 9 includes:

[0085] Second support frame;

[0086] The second transfer assembly 20 is slidably connected to the second support frame; the upper surface of the second transfer assembly 20 has a third conveying device that is horizontally arranged from one side of the second lifting assembly 9 to the other side.

[0087] The second lifting component 71 is fixed to the second support frame and is used to drive the second transfer component 20 to slide along the height direction of the second support frame;

[0088] The push-in component 8 is disposed on the second transfer component 20. The push-in component 8 can extend or retract toward the second lifting assembly 9 and push the sterilization tray 2 on the third conveying device into the drawer-type sterilization cart 1.

[0089] Compared to existing technologies that use a production mode where sterilization trays 2 are pushed into a drawer-type sterilization cart 1, most still involve manual removal of the sterilization trays 2 from the drawer-type sterilization cart 1, followed by manual or semi-manual / semi-mechanical loading of infusion drugs into the sterilization trays 2, and then manual pushing of the loaded sterilization trays 2 into the drawer-type sterilization cart 1. This process is labor-intensive and inefficient. This invention provides a mechanism for transferring fully loaded sterilization trays 2, specifically for the flexible and plastic packaging industry. It is particularly suitable for the large-volume infusion pharmaceutical industry that uses a drawer-type sterilization cart 1 to transfer drugs into and out of a water bath sterilizer via a track. This solution can automatically push fully loaded sterilization trays 2 into the drawer-type sterilization cart 1, improving loading efficiency. In the specific scheme, the drawer-type sterilization cart 1 without sterilization tray 2 is located on the side of the second lifting assembly 9. The drawer-type sterilization cart 1 is positioned by the second track locator 66 of the sterilization cart to ensure that the drawer-type sterilization cart 1 is aligned with the sterilization tray 2 pushing component 8. Then, the second lifting component 71 on the second support frame is activated, which drives the second transfer component 20 to rise and fall, so that the third conveying device on the second transfer component 20 is aligned with the placement position of the drawer-type sterilization cart 1. After alignment, the pushing component 8 is controlled to extend into the drawer-type sterilization cart 1, thereby pushing the corresponding full sterilization tray 2 into the drawer-type sterilization cart 1, completing the pushing in of a single full sterilization tray 2.

[0090] In this embodiment, to facilitate the rapid reception of full sterilization trays 2, a fourth conveying device 22 is provided on the other side of the second lifting assembly 9. The fourth conveying device 22 and the third conveying device have the same conveying direction, and the lifting of the second transfer component 20 can make the third conveying device and the fourth conveying device 22 level. The fourth conveying device 22 is used to convey its own sterilization trays 2 to the third conveying device. In this solution, the fourth conveying device 22 can be selected by means of conveyor belt or chain conveying, etc., to transport sterilization trays 2 filled with medicines. When the second lifting assembly 9 controls the third conveying device and the fourth conveying device 22 to be level, the fourth conveying device 22 can then transport the full sterilization trays 2 into the third conveying device. Then, the third conveying device is controlled to rise to be level with the placement position of the drawer-type sterilization cart 1, and the full sterilization trays 2 can be pushed into the drawer-type sterilization cart 1 by the pushing component 8.

[0091] In this embodiment, as a specific implementation of the push-in component 8, the push-in component 8 includes a second bracket spanning above the third conveying device. The second bracket is provided with a push-in pneumatic component 61. The output end of the push-in pneumatic component 61 is equipped with a push-in claw and thorn component 56, which is used to drive the claw and thorn component 56 to extend or retract toward the second lifting assembly 9.

[0092] The claw-like assembly 56 includes a connecting rod, the end of which has an L-shaped push rod. The upper end of one side of the L-shaped push rod is connected to the end of the connecting rod, and the other end of the L-shaped push rod faces the drawer-type sterilization cart 1. In this solution, the push-in pneumatic assembly 61 is mounted on the third conveying device by a second bracket spanning above the third conveying device, thus facilitating the entry of the full sterilization box onto the third conveying device. The output end of the push-in pneumatic assembly 61 has a push-in claw-like assembly 56, which is preferably a telescopic cylinder, thereby controlling the extension or retraction of the push-in claw-like assembly 56. The push-in claw-like assembly 56 includes a connecting rod, and the end of the connecting rod has an L-shaped push rod. During the push-in process, the other end of the L-shaped push rod is placed in front of the sterilization tray 2, and the cylinder extends to push the sterilization tray 2 into the drawer-type sterilization cart 1.

[0093] In this embodiment, to prevent obstruction of the entry of the sterilization tray 2, the end of the connecting rod has a through hole. The upper end of one side of the L-shaped push rod extends from the through hole to the top of the connecting rod and is hinged to the connecting rod at the through hole position. The L-shaped push rod can rotate towards the drawer-type sterilization cart 1. A cylinder is hinged to the upper side of the connecting rod, and the output end of the cylinder is hinged to the upper end of one side of the L-shaped push rod. In this solution, since the sterilization tray 2 needs to be transferred from the fourth conveying device 22 to the third conveying device, if the L-shaped push rod is vertically downward, it will obstruct the entry of the sterilization tray 2. Therefore, the upper end of the L-shaped push rod is hinged to the connecting rod and can rotate towards the drawer-type sterilization cart 1. A cylinder is provided on the upper side of the connecting rod. Through the extension and retraction control of the cylinder, the L-shaped push rod can be driven to rotate. When the sterilization tray 2 enters the third conveying device, the cylinder retracts, causing the L-shaped push rod to rotate towards the drawer-type sterilization cart 1, making one side horizontal, thus allowing the tray 2 to enter. The space through which the sterilization tray 2 passes; when the sterilization tray 2 reaches the designated position on the third conveying device, the cylinder extends, and both ends of the cylinder are hinged, thereby changing the L-shaped push rod to a vertical state. At this time, the other end of the L-shaped push rod is located on the front side of the sterilization tray 2. Therefore, at this time, the control push pneumatic component 61 extends, which can drive the L-shaped push rod to push the sterilization tray 2 into the drawer-type sterilization cart 1; wherein the connecting rod is preferably a channel steel with its opening facing downward. When the L-shaped push rod rotates to the horizontal position, one side of its opening can rotate into the channel steel, thereby leaving more gap below.

[0094] In this embodiment, in order to improve the stability of pushing in the full sterilization tray 2 and prevent the sterilization tray 2 from shifting during the pushing process, both sides of the output end of the pushing pneumatic component 61 are equipped with pushing claw assemblies 56.

[0095] In this embodiment, to guide the extension and retraction paths, a number of guide rods are also fixed on the second bracket, and the push-in claw assembly 56 is slidably connected to the guide rods.

[0096] In this embodiment, as a specific implementation of the second lifting component 71, the second lifting component 71 includes a second lifting reducer 50 disposed on the top of the second support frame. Second lifting sprockets 48 are fitted onto the second lifting drive shafts 49 on both sides of the second lifting reducer 50. A driven wheel is located at the bottom of the second support frame. Second lifting chains 51 are disposed on the second lifting sprockets 48 and the driven wheels. The second transfer component 20 is connected to two second lifting chains 51 on both sides. In this design, the second lifting reducer 50 is located at the top center of the second support frame, with second lifting drive shafts 49 on both sides, thereby driving the two second lifting sprockets 48 to rotate. A driven wheel is located directly below the second lifting sprockets 48, and a second lifting chain 51 is fitted onto it, thereby controlling the transmission of the second lifting chain 51. The second lifting chain 51 is used to achieve the lifting and lowering of the second transfer component 20.

[0097] In this embodiment, to achieve guidance in the lifting direction, the second support frame is also equipped with a plurality of second lifting guide shafts 52, and the second transfer assembly 20 and the second lifting guide shafts 52 are slidably connected. The second transfer assembly 20 can be slidably connected to the second lifting guide shafts 52 via a second linear bearing 47.

[0098] In this embodiment, as a specific implementation of the third conveying device, the second transfer component 20 includes a second support plate, and both sides of the second support plate are provided with synchronously moving third conveying multi-row chains 46. The second support plate is also provided with a third conveying transmission reducer 53 for driving the third conveying multi-row chains 46 to run.

[0099] In this embodiment, to facilitate the detection of the position of the sterilization tray 2, the second support plate is also provided with a third detection switch 80 for detecting whether the sterilization tray 2 has completely entered the third conveying device.

[0100] Example 4: This Example 4 also provides a bottle loading method for an automatic bottle loading device with a drawer-type tray box, such as... Figure 1 As shown, the specific steps include the following:

[0101] The drawer-type sterilization cart 1 is filled with empty sterilization trays 2 and is located on the side of the first lifting assembly 4 of the empty sterilization trays 2. The drawer-type sterilization cart 1 is positioned by the first track positioner 11 of the sterilization cart to ensure that the empty sterilization trays 2 in the drawer-type sterilization cart 1 are aligned with the sterilization tray 2 removal component 3. Then, the first lifting assembly 17 on the first support frame is activated, which drives the first transfer assembly 5 to rise in the direction of arrow 100, so that the first conveying device on the first transfer assembly 5 is aligned with the empty sterilization trays 2 to be removed. After alignment, the removal component 3 is controlled to extend into the drawer-type sterilization cart 1, and the front side of the pawl 45 touches the edge of the sterilization tray 2. At this time, the pawl 45... Rotating in the opposite direction, when the pawl 45 enters the sterilization tray 2, it hangs freely under its own weight. The control rod then retracts. During retraction, because the pawl 45 is inside the sterilization tray 2 and has a limiting component restricting its rotation, the rear side of the pawl 45 touches the inner edge of the sterilization tray 2, pulling it back a certain distance towards the first conveying device. Preferably, there are three pawls 45. Under the control of the electronic control system 12, the pneumatic assembly 39 extends and retracts three times to pull all the empty sterilization trays 2 back onto the first conveying device, completing the removal and transfer of a single empty sterilization tray 2. After removing the empty sterilization tray 2, it can be lowered by the first lifting assembly 17 in the direction of arrow 101, aligning the first conveying multi-row chain 43 of the first conveying device with the second conveying multi-row chain of the second conveying device 21. Then, the first and second conveying devices 21 are activated to convey the empty sterilization tray 2 onto the second conveying device 21.

[0102] After the sterilization tray 2 enters the second conveying device 21, its specific position is detected by the fourth detection device. The sterilization tray 2 is located directly above the second horizontal conveying device 24. Then, the third lifting component is activated to control the second conveying device 21 to descend, so that the sterilization tray 2 lands on the second horizontal conveying device 24. At this time, the second horizontal conveying device 24 is activated and moves forward along arrow 103 to transport the sterilization tray 2 into the first horizontal conveying device 23, while keeping the orientation of the sterilization tray 2 unchanged. The first transverse conveyor 23 is equipped with a bottle gripping mechanism assembly 6. Two sets of bottle gripping robots on the bottle gripping mechanism assembly 6 grip the medicines conveyed by the bottle conveying line 13 and the bottle conveying line 14 and evenly separated by the equally spaced bottle separating mechanism 15, and place them into the sterilization tray 2. At this time, the full sterilization tray 2 continues to be conveyed by the first transverse conveyor 23 along arrow 103 to the third transverse conveyor 25. In the initial state, the fourth conveyor 22 is located below the third transverse conveyor 25. When the first transverse conveyor 23 conveys the full sterilization tray 2 to the third transverse conveyor 25 and the specific position is detected by the fifth detection device, the fourth lifting component is controlled to drive the fourth conveyor 22 to rise, so that the full sterilization tray 2 can be conveyed to the fourth conveyor 22.

[0103] The drawer-type sterilization cart 1, without the sterilization tray 2, moves to the side of the second lifting assembly 9. The drawer-type sterilization cart 1 is positioned by the second track positioner 66, ensuring alignment between the drawer-type sterilization cart 1 and the sterilization tray 2 push-in assembly 8. The bottle-grabbing mechanism grabs several medicines into the sterilization tray 2 and then transports them to the fourth conveying device 22. Subsequently, the second lifting assembly 71 on the second support frame is activated. When the third and fourth conveying devices 22 are aligned, a cylinder on the side of the connecting rod drives the L-shaped push rod to rotate through the extension and retraction control of the cylinder. When the sterilization tray 2 enters the third conveying device, the cylinder retracts. The L-shaped push rod is rotated towards one side of the drawer-type sterilization cart 1, making one side horizontal, thus leaving space for the sterilization tray 2 to pass through. At this time, the fourth conveying device 22 can transport the full sterilization tray 2 to the third conveying device. When the sterilization tray 2 reaches the designated position on the third conveying device, the cylinder extends, thereby changing the L-shaped push rod to a vertical position. At this time, the other end of the L-shaped push rod is located in front of the sterilization tray 2. Then, the third conveying device is controlled to rise to be level with the placement position of the drawer-type sterilization cart 1. At this time, the push-in pneumatic component 61 is controlled to extend, which can drive the L-shaped push rod to push the sterilization tray 2 into the drawer-type sterilization cart 1.

[0104] The above-described automatic bottle loading device and method for drawer-type trays and boxes allows for the automatic removal of sterilization trays and boxes 2 at different heights within the drawer-type sterilization cart 1. After removal, the trays and boxes 2 at different positions within the cart 1 are automatically adjusted to the same height as the first transfer component 5 and the empty box reversing unit 64. The trays and boxes 2 then rotate 90 degrees and are automatically transferred to the infusion drug loading station. After loading, they rotate 90 degrees again and are transported to the full box reversing unit 65, where they are transferred by the second transfer component 20 and raised to the corresponding loading height within the drawer-type sterilization cart 1. Finally, the filled trays and boxes 2 are transported (pushed) into the drawer-type sterilization cart 1 to complete the loading process. This invention employs a U-shaped layout to minimize the turning radius and save on production area. The entire process is fully automated, requiring no manual intervention or assistance.

It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
