DETAILED DESCRIPTION

[0028] The present invention is not limited to the following embodiments, and specific implementation methods can be determined based on the technical solutions of the present invention and actual conditions.

[0029] In the present invention, for the convenience of description, the relative position relationship of each component is described based on the Figure 1 For example, the positional relationships of front, back, up, down, left, and right are determined according to the layout directions of the drawings in the specification.

[0030] The present invention will be further described below in conjunction with the embodiments and accompanying drawings:

[0031] As attached Figure 1-11 As shown, the large infusion bottle automatic loading and unloading tray system includes a frame 21, a sterilization tray, a conveyor belt 22, a tray lifting and placing mechanism and a pushing mechanism. The frame 21 is provided with a tray lifting and placing mechanism for lifting the sterilization tray to the height of the loading and unloading tray. The sterilization tray includes a tray body 1 with an opening on the right side. The tray body 1 is provided with a bottle hanging slide group that can be moved to the right to the outside of the tray body 1. The bottle hanging slide group includes a number of bottle hanging slides 2 arranged left and right. The bottom of the bottle hanging slide 2 is provided with a longitudinally arranged bottle hanging groove 4 that cooperates with the bottle mouth of the infusion bottle 37. The frame 21 is provided with a pushing mechanism for pushing the bottle hanging slide group to the top of the conveyor belt 22 and pulling back the bottle hanging slide group when the sterilization tray is at the height of the loading and unloading tray. The conveyor belt 22 is used to send the infusion bottle 37 into the hanging bottle groove 4 or move the infusion bottle 37 in the hanging bottle groove 4 out when the bottle hanging slide group moves to the top of the conveyor belt 22.

[0032] When loading, the tray lifting and placing mechanism lifts an empty sterilization tray to the height of the loading and unloading tray, and then the pushing mechanism pushes the bottle hanging slide group to the right to above the conveyor belt 22. The infusion bottles 37 on the conveyor belt 22 are arranged in several rows on the left and right, and the bottle mouths of the infusion bottles 37 in each row are aligned with a bottle hanging slot 4 front and back. The conveyor belt 22 transports the infusion bottles 37 longitudinally so that the bottle mouths of the infusion bottles 37 move to the bottle hanging slot 4. When the bottle hanging slot 4 is full of infusion bottles 37, the pushing mechanism retracts the bottle hanging slide group to the left into the tray body 1, and then the tray lifting and placing mechanism drives the fully loaded sterilization tray to descend and puts down the sterilization tray.

[0033] When unloading the tray, the tray lifting and placing mechanism lifts the sterilization tray with infusion bottles 37 hanging in a bottle hanging slot 4 to the height of the loading and unloading tray, and then the pushing mechanism pushes the bottle hanging slide group to the right to above the conveyor belt 22. At this time, the infusion bottle 37 just sits on the conveyor belt 22, and then the conveyor belt 22 transports the infusion bottle 37 longitudinally so that the bottle mouth of the infusion bottle 37 moves out of the bottle hanging slot 4. When all the infusion bottles 37 in the bottle hanging slot 4 are moved out, the pushing mechanism retracts the bottle hanging slide group to the left into the tray body 1, and then the tray lifting and placing mechanism drives the empty sterilization tray to descend and puts down the sterilization tray.

[0034] The infusion bottle 37 includes a bottle mouth, a bottle body and a bottleneck located between the bottle mouth and the bottle body. The infusion bottle 37 matched with the bottle hanging groove 4 can be specially designed according to needs. The outer diameter of its bottle mouth is larger than the outer diameter of the bottleneck. The bottle mouth and bottleneck of the infusion bottle 37 form a two-level stepped cylindrical structure with a larger upper part and a smaller lower part. The hanging bottle groove 4 is a T-shaped groove. The width of the opening at the bottom end of the hanging bottle groove 4 is larger than the outer diameter of the bottleneck of the infusion bottle 37 and smaller than the outer diameter of the bottle mouth of the infusion bottle 37. Therefore, the bottle mouth of the infusion bottle 37 can be hung in the hanging bottle groove 4; specifically, in this embodiment, the hanging bottle slide group includes 6 hanging bottle slides 2 arranged left and right.

[0035] The height of the loading and unloading tray is set according to the height of the conveyor belt 22. Specifically, the hanging bottle groove 4 of the sterilization tray at the height of the loading and unloading tray and the bottle mouth of the infusion bottle 37 on the conveyor belt 22 are at the same height as the condition.

[0036] Through the setting of this application, the automatic operation of loading and unloading the infusion bottles is realized, greatly reducing the labor intensity of the operators and reducing the labor cost of manual operation.

[0037] According to actual needs, the above embodiments can be further optimized or / and improved:

[0038] As shown in the appendix Figure 4-6 As shown, the sterilization tray further includes a cross-shaped telescopic frame and several baffles 3. The several baffles 3 and several hanging bottle slides 2 are alternately arranged in sequence from left to right and are connected together by the cross-shaped telescopic frame. The cross-shaped telescopic frame includes multiple cross units hinged in sequence from left to right. The cross unit includes two support rods 5 hinged in an "X" shape through a first hinge shaft 6. Adjacent two cross units are hinged together through two second hinge shafts 7. The top of the baffle 3 is fixedly connected to the first hinge shaft 6. The top of the hanging bottle slide 2 is provided with a slot for the lower end of the second hinge shaft 7 to slide. The lower end of the second hinge shaft 7 is longitudinally slidably installed in the slot. Transverse chutes 8 with open right ends are respectively opened on the front and rear side plates of the tray body 1. The front and rear ends of the baffle 3 and the hanging bottle slide 2 are respectively slidably installed in the transverse chutes 8 on the front and rear sides.

[0039] The process requirement of the water bath sterilization of the large infusion bottle 37 is that the temperature is higher than 100 °C. At this stage, the large infusion bottle 37 will expand to both sides. If these expansions are not controlled or restricted, it will cause the infusion bottle 37 to deform. In this application, the baffles 3 and the hanging bottle slides 2 are alternately arranged in sequence from left to right. The distance between adjacent two baffles 3 is equal to the body width of the infusion bottle 37. When the hanging bottle slide 2 is hung with the infusion bottle 37 and retracted into the tray body 1, each infusion bottle 37 on the hanging bottle slide 2 is clamped by two baffles 3 on its left and right sides. Thus, it can prevent the infusion bottle 37 from deforming during the water bath sterilization. The baffles 3 and the hanging bottle slides 2 are connected together by the cross-shaped telescopic frame. When the baffles 3 and the hanging bottle slides 2 are moved out of the tray body 1, the cross-shaped telescopic frame plays a supporting role for both of them. In addition, when the hanging bottle slide 2 is retracted into the tray body 1, the cross-shaped telescopic frame is in a contracted state. At this time, the distance between adjacent two baffles 3 is equal to the body width of the infusion bottle 37. And when the hanging bottle slide 2 is moved out above the conveyor belt 22, the cross-shaped telescopic frame is in an extended state. At this time, the distance between adjacent two baffles 3 is greater than the body width of the infusion bottle 37. Thus, the presence of the baffle 3 will not prevent the infusion bottle 37 from entering or exiting the hanging bottle groove 4. Specifically, in this scheme, the tray body 1 can be a "匚"-shaped frame structure formed by enclosing the front side plate, the rear side plate, and the left side plate, which is vertically through and the opening faces right.

[0040] Specifically, a horizontally disposed limit slot is provided on the inner wall of the transverse chute 8, with a closed right end. Limit sliders are provided at the front and rear ends of the leftmost baffle 3, respectively, which slide within the limit slot. This prevents the baffle 3 and the cross-type telescopic frame from being completely pushed out of the tray body 1 when the pushing mechanism pushes the bottle hanging chute 2 to the right.

[0041] As attached Figure 1 、 2 As shown in Figure 8, the pushing mechanism includes a pushing rod 23, a pushing sleeve 24 and a first driving device 25. The pushing rod 23 is installed on the frame 21 through the first driving device 25. The first driving device 25 is used to drive the pushing rod 23 to move back and forth laterally. The pushing rod 23 is fixedly connected with a pushing sleeve 24 that can be sleeved on the upper end of the first hinge shaft 6 on the far right when the sterilization tray is at the height of the loading and unloading tray. According to requirements, the first drive device 25 can adopt existing well-known technology, such as a hydraulic cylinder, an air cylinder, an electric push rod or a transverse moving device. In this embodiment, it is an electric push rod. When the sterilization tray is lifted to the height of the loading and unloading tray by the tray lifting and placing mechanism, the upper end of the first hinge shaft 6 on the far right of the sterilization tray is just inserted from bottom to top into the pushing sleeve 24, and then when the first drive device 25 drives the pushing rod 23 to move to the right, the cross-type telescopic frame is pulled to the right and stretched, thereby driving the bottle hanging slide 2 to move to just above the conveyor belt 22. When the bottle is loaded or unloaded, the first drive device 25 drives the pushing rod 23 to move to the left, and the cross-type telescopic frame is pulled to the left and retracted into the tray body 1, and then the bottle hanging slide 2 is completely retracted into the tray body 1, thereby realizing the push-out or retraction of the bottle hanging slide group.

[0042] A locking frame is rotatably mounted on the tray body 1 for preventing the bottle hanging slide group from moving out of the tray body 1, and the locking frame can unlock the bottle hanging slide group when it is flipped upward to an unlocking position; an unlocking mechanism is provided on the frame 21, which is used to lift the locking frame upward to unlock the bottle hanging slide group when the sterilization tray is at the height of the loading and unloading tray, and lower the locking frame after the pushing mechanism pulls back the bottle hanging slide group. When the bottle hanging slide group is pushed to the top of the conveyor belt 22, the unlocking mechanism first lifts the locking frame upward to release the locking effect of the bottle hanging slide group. At this time, the bottle hanging slide group can be pushed to the right to the top of the conveyor belt 22 under the action of the pushing mechanism to load or unload the bottle. When the bottle loading or unloading is completed, the pushing mechanism pulls the bottle hanging slide group back into the tray body 1, and the unlocking mechanism lowers the locking frame, which flips downward under its own gravity to lock the bottle hanging slide group again.

[0043] As attached Figure 4 、 9 As shown, the locking frame includes a fixed shaft 9, a spring-type telescopic rod and a U-shaped limit rod 10. A fixed shaft 9 is provided on the top left side of the tray body 1 in the longitudinal direction. Two spring-type telescopic rods are rotatably installed on the fixed shaft 9. A U-shaped limit rod 10 is fixedly connected between the right ends of the two spring-type telescopic rods. The left side of the U-shaped limit rod 10 is against the right side of the rightmost baffle 3. The spring-type telescopic rod includes a first rod body 11, a second rod body 12, a first sleeve 13, a second sleeve 14, a return spring 15, a connecting rod 16 and a limiting portion 17. The first rod body 11 and the second rod body 12 are arranged left and right. The upper side of the right end of the first rod body 11 is fixedly connected to the first sleeve 13, and the second sleeve 14 is fixedly connected to the connecting rod 16. A second sleeve 14 is fixedly connected to the upper left end of the second rod body 12, and a connecting screw is inserted into the first sleeve 13 and the second sleeve 14. A limit portion 17 is respectively provided at the left and right ends of the connecting screw. A return spring 15 is respectively provided on the connecting rod 16 corresponding to the position between the first sleeve 13 and the left limit portion 17 and the connecting rod 16 corresponding to the position between the second sleeve 14 and the right limit portion 17; the unlocking mechanism includes a lifting rod 26, an L-shaped lever 27 and a second driving device 28. The lifting rod 26 is installed on the frame 21 through the second driving device 28. The second driving device 28 is used to drive the lifting rod 26 to reciprocate longitudinally. The lower end of the lifting rod 26 is fixedly connected to the L-shaped lever 27.

[0044] When the locking frame is in the locked position, the first rod 11 and the second rod 12 are in a horizontal state and sit on the baffle 3 and the bottle hanging slide 2, the return spring 15 is in a compressed state, the right end of the first rod 11 and the left end of the second rod 12 are against each other, and the first rod 11 and the second rod 12 tend to be close to each other under the action of the return spring 15, and the left side of the U-shaped limit rod 10 is against the right side of the rightmost baffle 3, thereby preventing the baffle 3 and the bottle hanging slide 2 from moving outward, and then when an infusion bottle 37 is hung on the bottle hanging slide 2 When the first rod 11 and the second rod 12 are pressed against each other under the action of the return spring 15, when the entire spring-type telescopic rod is subjected to an upward lifting force, the spring-type telescopic rod overcomes the elastic force and stretches under the action of the lifting force, so that the entire locking frame can be lifted upward to separate the U-shaped limit rod 10 from the baffle 3, thereby releasing the locking effect on the bottle hanging slide 2. After the lifting force is removed, the locking frame flips down to its initial position under the action of its own gravity. The bottle hanging slide 2 is locked again; the specific process of the unlocking mechanism lifting the locking frame upward is as follows: first, the lifting device 29 drives the L-shaped lever 27 downward to the rear and lower part of the second rod body 12 on the front side, and then the second driving device 28 drives the lifting rod 26 to move forward so that the horizontal rod section of the L-shaped lever 27 moves to just below the second rod body 12, and then the lifting rod 26 drives the L-shaped lever 27 upward, and the L-shaped lever 27 lifts the second rod body 12 upward, thereby lifting the entire locking frame upward; and when the locking frame is to be lowered, only the second driving device 28 is required to drive the lifting rod 26 to move forward so that the horizontal rod section of the L-shaped lever 27 moves to just below the second rod body 12. The driving device 28 drives the lifting rod 26 to move backward, and the horizontal rod section of the L-shaped lever 27 is separated from the second rod body 12. The second rod body 12 loses the supporting function of the L-shaped lever 27, and the entire locking frame flips downward to the initial position under the action of its own gravity. According to requirements, the lifting rod 26 and the second driving device 28 can both be existing well-known technologies. For example, the lifting rod 26 can be a hydraulic cylinder, a cylinder and an electric push rod, and the second driving device 28 can be a hydraulic cylinder, a cylinder, an electric push rod, or a longitudinal moving device. In this embodiment, both are electric push rods.

[0045] As attached Figure 3 、 4As shown in Figures 7, 10 and 11, the front and rear side panels of the tray body 1 are respectively provided with bayonet holes 18; the tray lifting and placing mechanism includes a lifting device 29, a lifting frame 30, a block 31, a rack 32, a gear shaft 33 and a driving component 34. The lifting frame 30 is installed on the frame 21 through the lifting device 29. The lifting device 29 is used to drive the lifting frame 30 to move up and down, and a sterilization tray placement space is formed inside the lifting frame 30. Mounting grooves are respectively provided on the front and rear side panels of the lifting frame 30 corresponding to the positions of the front and rear bayonet holes 18. A block 31 that can move longitudinally and cooperates with the bayonet hole 18 is slidably installed in the mounting groove. The bottom of the block 31 is fixedly connected to the rack 32. A gear shaft 33 that meshes with the rack 32 is rotatably installed in the lifting frame 30. The driving component 34 is used to drive the gear shaft 33 to rotate to drive the block 31 to extend into or exit the bayonet hole 18. According to requirements, the lifting device 29 can adopt existing well-known technology, such as a hydraulic cylinder, an air cylinder, an electric push rod or a longitudinal moving device. In this embodiment, it is a hydraulic cylinder. When lifting the sterilization tray, the lifting device 29 first drives the lifting frame 30 downward to the outside of the sterilization tray, and then the driving component 34 drives the gear shaft 33 to rotate to drive the block 31 to extend into the bayonet 18. Then the lifting device 29 drives the lifting frame 30 upward to lift the sterilization tray to the loading and unloading tray height. After loading or unloading is completed, the lifting device 29 drives the lifting frame 30 downward. After placing the sterilization tray on the sterilization cart 40, the driving component 34 drives the gear shaft 33 to rotate to drive the block 31 to exit the bayonet 18, thereby lowering the sterilization tray. According to requirements, the driving component 34 is an existing well-known technology, such as it can be a drive motor.

[0046] As attached Figure 1 、 2 As shown, a plurality of guide plates 35 are provided above the conveyor belt 22, spaced apart from one another. A longitudinal guide channel 36 is formed between adjacent guide plates 35. When the bottle hanging slide assembly moves above the conveyor belt 22, the bottle hanging troughs 4 and the guide channels 36 correspond vertically. The guide plates 35 align the infusion bottles 37 on the conveyor belt along the longitudinal guide channels 36 during loading, facilitating their transfer to the bottle hanging troughs 4.

[0047] As attached Figure 1 、 2As shown, the automatic loading and unloading system for large infusion bottles also includes a controller and a frame 21 drive mechanism that drives the frame 21 to move horizontally back and forth. The tray lifting and placing mechanism, the pushing mechanism, the frame 21 drive mechanism, and the conveyor belt 22 are all controlled by the controller. Multiple sterilization trays can be stacked together. The frame 21 drive mechanism includes two parallel support rails 38 at the front and rear, running wheels installed on the frame 21 for rolling along the support rails 38 to drive the frame 21 to move along the support rails 38, and a third drive device that drives the running wheels to rotate. Two parallel sterilization vehicle rails 39 are provided between the two support rails 38. A sterilization vehicle 40 that can move horizontally along the sterilization vehicle rails 39 is provided on the two sterilization vehicle rails 39, and the sterilization trays can be stacked on the sterilization vehicle 40. Specifically, a vertical plug-in column 19 is provided at the bottom of the tray body 1, and a plug-in slot 20 that cooperates with the plug-in column 19 is provided at the top of the tray body 1.

[0048] According to the requirements, the third driving device can be a driving motor. In this solution, the controller controls the operation of the first driving device 25, the second driving device 28, the third driving device, the lifting device 29, the lifting rod 26, and the driving component 34.
