The system automatically unloads the infusion bags and transports them to the next process. During the forward rotation of the turntable, gravity helps to automatically clean and collect residual water from the tray and the surface of the infusion bags through the filter holes, discharge port, and water tank. The discharge port and water tank then perform a secondary automatic cleaning and collection of residual water from the tray, the surface of the infusion bags, and the conveyor end of the front bag conveyor. The barrier pads protect the quality of the infusion bags. Finally, as the turntable reverses and approaches the unloading plate, the clamping mechanism releases the tray, and gravity causes it to fall onto the recycling conveyor, automatically recovering the empty tray.

[0015] This utility model integrates multiple functions such as automatic layer-by-layer feeding of stacked pallets, automatic clamping and limiting, automatic flipping and unloading, and automatic water filtration and collection. It has a high degree of automation and avoids the problems of manual bending over to carry pallets layer by layer, manual picking and placing of infusion bags, and manual slippage that causes damage to the quality of infusion bags. Overall, it has the advantages of high bag unloading efficiency, low labor intensity and good product quality. Attached Figure Description

[0026] To explain the technical content, objectives, and effects of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings. It should be noted that the terms "upper" and "lower" used in the following description refer to the attached drawings. Figure 2 The direction in the middle, the words "bottom" and "top" refer to the attached Figure 1 and Figure 4 The direction of the center of a specific component's geometry is the same as the direction in which the rear soft bag conveyor transports the infusion soft bags.

[0027] The most crucial concept of this utility model lies in the following: The frame 3, the first lifting component, and the pushing mechanism automatically feed the stacked pallets 2 to be unloaded; the support plate 9 and the clamping mechanism limit and clamp the three sides of the pallet 2 inside the rotating box 1, preventing slippage when manually grasping the pallet 2; the second lifting component 8 automatically drives the pallet 2 to abut against the lower conveying end face of the front soft bag conveyor 7, further limiting the pallet 2; the flipping mechanism, the front soft bag conveyor 7, and the rear soft bag conveyor automatically unload the infusion soft bags; during the forward flipping process of the rotating box 1, the filter holes 13, the discharge port 5, the water outlet 6, and the water receiving tank 15 automatically clean and collect residual water inside the pallet 2 and on the surface of the infusion soft bags multiple times; the barrier pad 14 protects the quality of the infusion soft bags; and the unloading plate 12 and the recycling conveyor 11 automatically recycle the empty pallets 2.

[0028] This utility model integrates multiple functions such as automatic layer-by-layer feeding of stacked trays 2, automatic clamping and limiting, automatic flipping and unloading, and automatic water filtration and collection. It has a high degree of automation and avoids the problems of manual bending and carrying of trays 2, manual picking and placing of infusion bags, and manual slippage that causes damage to the quality of infusion bags. Overall, it has the advantages of high bag unloading efficiency, low labor intensity and good product quality.

[0029] Please refer to Figures 1 to 9 As shown, a stackable tray unloading device for infusion bags includes a rotating box 1, a tray 2, a frame 3 for stacking the trays 2, and a first lifting component for driving the frame 3 to lift. The rotating box 1 has an inlet 4, an outlet 5, and a water outlet 6 on its front, rear, and upper sides, respectively. A second lifting component 8 and a front soft bag conveyor 7 are installed inside the rotating box 1. The drive end of the second lifting component 8 is connected to a support plate 9 located below the front soft bag conveyor 7. The support plate 9 is connected to a clamping mechanism for clamping both sides of the tray 2. A frame is provided outside the inlet 4. The upper tray 2 is pushed onto the support plate 9 by a material pushing mechanism. A rear soft bag conveyor and a recycling conveyor 11 are provided from top to bottom outside the discharge port 5. The other two sides of the turntable 1 are connected to a turning mechanism that drives it to rotate 180° forward and backward until the front soft bag conveyor 7 and the rear soft bag conveyor are flush. The front end of the recycling conveyor 11 is connected to a tray unloading plate 12 that is inclined upward toward the discharge port 5. Several water filter holes 13 are opened on the rear side of the tray 2. A barrier pad 14 is connected to the inner rear side of the tray 2. A water receiving tank 15 is provided below the turntable 1.

[0030] As described above, the sterilized stacked trays 2 are still placed on the frame 3 in a top-to-bottom stacking manner. When it is necessary to unload the infusion bags, firstly, the first lifting mechanism is activated. The drive end of the first lifting mechanism drives the frame 3 down until the bottom tray 2 is directly in front of the inlet 4. Then, the pushing mechanism is activated. The drive end of the pushing mechanism extends and pushes the bottom tray 2 of the frame 3 through the inlet 4 of the turntable 1 and onto the support plate 9 inside the turntable 1 until the tray 2 is pushed to the clamping mechanism. Then, the clamping mechanism is activated to clamp the two sides of the tray 2. Then, the second lifting mechanism is activated. The drive end of the second lifting mechanism drives the support plate 9 and the tray 2 clamped by the clamping mechanism to rise together towards the front soft bag conveyor 7 until the tray 2 is fully unloaded. The upper surface of tray 2 abuts against the lower conveying end face of the front soft bag conveyor 7; then, the flipping mechanism is activated, and the drive end of the flipping mechanism drives the rotating box 1 to flip backward in the width direction of the front soft bag conveyor 7. During this flipping process, when the support plate 9 and the tray 2 containing the infusion soft bag are in an inclined or vertical state with the rear side of the tray 2 facing down, under the action of gravity, the water in the tray 2 and the surface of the infusion soft bag fall into the water receiving tank 15 below the rotating box 1 through the water filter hole 13 and the discharge port 5, which plays the role of automatically cleaning and collecting the residual water in the tray 2 and the surface of the infusion soft bag; the barrier pad 14 is used to block the infusion soft bag from the water filter hole 13, so as to avoid the infusion soft bag from being scratched or damaged due to impact and friction with the edge of the water filter hole 13, thus protecting the quality of the infusion soft bag product;

[0031] After the rotating box 1 rotates 180° in the forward direction, the support plate 9 is on top and the front soft bag conveyor 7 is on the bottom. At this time, the upper conveying end face of the front soft bag conveyor 7 is flush with the upper conveying end face of the rear soft bag conveyor. The tray 2, which is clamped by the clamping mechanism, is upside down on the upper conveying end face of the front soft bag conveyor 7. Then, the drive end of the second lifting component 8 retracts, causing the support plate 9 and the tray 2 clamped by the clamping mechanism to rise together away from the front soft bag conveyor 7 until the infusion soft bag is completely separated from the tray 2. At this time, under the action of gravity, the infusion soft bag and the tray 2 are separated. Water on the surface and water at the lower conveying end of the front soft bag conveyor 7 fall into the water receiving tank 15 through the water outlet 6. This serves to automatically clean and collect water from the tray 2 and the surface of the infusion soft bags, preventing any impact on the handling, subsequent conveying, and maintenance of the infusion soft bags, as well as on the subsequent use of the tray 2. Finally, the front soft bag conveyor 7 is started to transport the multiple inverted infusion soft bags together to the rear soft bag conveyor. The rear soft bag conveyor then transports the bags to the next process, thus achieving automatic unloading of the infusion soft bags.

[0032] After the infusion soft bags are conveyed to the rear soft bag conveyor, the flipping mechanism drives the rotating box 1 to reset and flip in the reverse direction, thereby driving the front soft bag conveyor 7, support plate 9, second lifting component 8, clamping mechanism and empty tray 2 to reset and flip in the reverse direction together. When the reset and reverse flipping is close to the unloading plate 12 behind the support plate 9 (reverse flipping at a preset angle or time), the clamping mechanism is released. Since the support plate 9 is tilted at this time, under the action of gravity, the tray 2 slides from the support plate 9 through the discharge port 5 and onto the recycling conveyor 11 through the unloading plate 12, which plays the role of automatically recycling the empty tray 2. When the flipping mechanism resets the rotating box 1 and flips it in the reverse direction by 180° so that the support plate 9 is below and the front soft bag conveyor 7 is above, the first lifting component drives the new bottom tray 2 of the frame 3 to descend to the inlet 4. The above unloading steps are repeated until all the infusion soft bags in the trays 2 in the frame 3 are unloaded onto the rear soft bag conveyor.

[0033] Furthermore, the frame 3 includes a base 16 and two sets of trays 17 for supporting the bottom sides of the tray 2 respectively; the base 16 is equipped with self-locking casters at the bottom, and both sides are equipped with inverted U-shaped brackets 18. A fixed frame 19 is connected between the two vertical sections of the bracket 18 and slides up and down. The two sets of trays 17 are detachably fixed to one side of the two fixed frames 19 respectively. The trays 17 in the same set are evenly arranged along the vertical section of the bracket 18. A baffle 20 for blocking the rear side of the tray 2 is fixedly connected between the upper ends of the two brackets 18 near the turntable 1. The drive end of the first lifting component is connected to the fixed frame 19.

[0034] As described above, when the sterilized stacked tray 2 needs to be placed on the frame 3, the frame 3 can be manually moved to the sterilization stage because the base 16 of the frame 3 is equipped with casters. Then, the first lifting component drives the fixed frame 19 to rise gradually. The trays 17 on the two fixed frames 19 are used to support the bottom sides of the tray 2. The tray 2 containing the sterilized infusion bag is placed on the trays 17 from top to bottom. The two vertical sections of the two fixed frames 19 located on both sides of the base 16 limit the left and right sides of the tray 2 until it is fixed. When the fixed frame 19 rises to its highest position, it can transfer the stacked trays 2 inside the sterilizer to the frame 3 without bending over. Then, the frame 3, which is full of trays, is manually pushed between the feed inlet 4 and the feeding mechanism. The casters of the base 16 are locked. After that, the fixed frame 19 is driven to descend gradually and multiple times by the first lifting component. Each descent is a preset height. The feeding mechanism pushes the bottom tray 2 to the feed inlet 4, which can realize the automatic feeding of the stacked trays 2 from bottom to top. The rear side of the tray 17 is blocked and limited by the baffle 20.

[0035] Furthermore, the first lifting component includes two threaded rods 21; one end of the threaded rod 21 is rotatably connected to the horizontal section of the bracket 18, and the other end is rotatably connected to both sides of the base 16. A stepper motor 22 is connected to the bottom of each of the two threaded rods 21, and a threaded sleeve 23 is threadedly connected to each of the threaded rods 21. One side of the threaded sleeve 23 is fixedly connected to the other side of the fixed frame 19.

[0036] As described above, when it is necessary to drive the stacked pallets 2 to rise and fall, the stepper motor 22 is started. The drive end of the stepper motor 22 rotates in the forward direction, driving the threaded rod 21 to rotate in the reverse direction. This causes the fixed frame 19 to move downwards a predetermined distance through the threaded sleeve 23, so that the bottom pallet 2 falls to the front of the feed port 4. After all the pallets 2 on the frame 3 are pushed into the rotating box 1, the drive end of the stepper motor 22 rotates in the reverse direction, driving the threaded rod 21 to rotate in the reverse direction. This causes the fixed frame 19 to rise to the reset position through the threaded sleeve 23, thus realizing the function of automatically driving the fixed frame 19 to rise and fall.

[0037] Furthermore, the pushing mechanism includes a translation cylinder 24, a push plate 25, and a pushing platform 26 located between two sets of pallets 17. The push rod of the translation cylinder 24 is fixedly connected to the push plate 25. The pushing platform 26 is located between the support plate 9 and the translation cylinder 24. The baffle 20 is located above the pushing platform 26, and a channel 27 is formed between its bottom and the pushing platform 26 for the pallet 2 and the push plate 25 to pass through. The bottom of the translation cylinder 24 is connected to a linear guide rail 46 that drives it to translate towards the frame 3. The bottom of the linear guide rail 46 is connected to a support platform 48. The front bottom of the pushing platform 26 is rotatably connected to the rear bottom of the support platform 48. A support member 49 is detachably connected between the pushing platform 26 and the support platform 48.

[0038] As described above, after the first lifting component drives the frame 3 to descend until the bottom tray 2 is placed on the pushing platform 26, firstly, the linear guide 46 is activated. The motor of the linear guide 46 rotates in the forward direction, driving the slider of the linear guide 46 and the translation cylinder 24 to move towards the frame 3 until the translation cylinder 24 moves to the frame 3. Then, the translation cylinder 24 is activated again, and the push rod of the translation cylinder 24 extends, driving the push plate 25 to move the bottom tray 2 of the frame 3 through the channel 27 first, then... The material enters the support plate 9 inside the rotating box 1 through the feed port 4. After the pallet 2 is pushed to the clamping mechanism, the push rod of the translation cylinder 24 retracts, causing the push plate 25 to disengage from the pallet 2 and move away from the rotating box 1. The push rod of the translation cylinder 24 drives the push plate 25 to return to the frame 3. Then the linear guide rail 46 is activated, and the motor of the linear guide rail 46 rotates in the opposite direction, causing the translation cylinder to move away from the frame 3 and return to the initial position, thus automatically pushing the pallet 2 into the rotating box 1.

[0039] In addition, to facilitate the ejection of frame 3 from the pusher platform 26, simply remove the supporting function of support member 49 and flip the pusher platform 26 downwards to eject frame 3. If frame 3 needs to be pushed back to the front of feed port 4, similarly, open pusher platform 26 and turn on the supporting function of support member 49.

[0040] Furthermore, the top of the push plate 25 is connected to a drying hood 28 arranged in an inverted U-shape. A small blower 29 and a control module are installed on a vertical section of the drying hood 28, and a heating tube 30 is installed on a horizontal section of the drying hood 28. The air outlet of the small blower 29 is connected to an air diffuser 31 facing the upper surface of the infusion soft bag in the tray 2. A pressure sensor 32 is embedded in the push plate 25.

[0041] As described above, when the translation cylinder 24 is activated to push the tray 2 into the turntable 1, the external control heating tube 30 starts heating. When the push rod of the translation cylinder 24 drives the push plate 25 to touch the front side of the bottom tray 2 of the frame 3, the drying hood 28 moves together with the push plate 25 to directly above the bottom tray 2. The pressure sensor 32 sends the detected pressure signal to the control module, which then controls the small blower 29 to start. The heat generated by the small blower 29 and the heating tube 30 is used to blow onto the upper surface of the infusion bag in the tray 2 with the help of the air diffuser 31, thus initiating the initial drying effect. This continues until the push plate 25 pushes the tray 2 to the clamping mechanism, at which point the push rod of the translation cylinder 24 retracts, causing the push plate 25 to disengage from the tray 2 and move away from the turntable 1. At this point, the pressure sensor 32 does not detect a pressure signal. After receiving the no-pressure signal, the control module controls the small blower 29 until the push rod of the translation cylinder 24 retracts and returns to the frame 3, at which point the heating tube 30 is turned off.

[0042] Furthermore, the clamping mechanism includes a set of clamping cylinders 33 and a set of clamping plates 34, both of which are arranged in an inverted L-shape. The set of clamping cylinders 33 are respectively installed on both sides of the support plate 9. The line connecting the discharge port 5 and the inlet port 4 is located between the set of clamping cylinders 33. The outer side of the vertical section of the clamping plate 34 is detachably and fixedly connected to the top rod of the clamping cylinder 33. The outer sides of the tray 2 are provided with handles 35. The handles 35 are provided with grooves 36 for the horizontal section of the clamping plate 34 to pass through. The inner side of the vertical section of the clamping plate 34 is connected with an anti-slip pad 37.

[0043] As can be seen from the above description, when the pushing mechanism pushes the pallet 2 onto the support plate 9, the clamping cylinder 33 is activated. The top rod of the clamping cylinder 33 extends, causing the clamping plate 34 to move towards both sides of the pallet 2 until the horizontal section of the clamping plate 34 is inserted into the groove 36 of the handle part 35. The vertical section of the clamping plate 34 is pressed tightly against the side of the handle part 35 through the anti-slip pad 37, which plays the role of automatically clamping both sides of the pallet 2.

[0044] Furthermore, an electric push rod 38 is fixedly connected to the bottom of the rotating box 1. The top rod of the electric push rod 38 is connected to a set of positioning stops 39, which are all L-shaped and used to block the rear side of the tray 2. A through hole 40 is provided on the rear side of the support plate 9 for the upper end of the positioning stops 39 to pass through.

[0045] As can be seen from the above description, when the pushing mechanism pushes the pallet 2 onto the support plate 9, the positioning stop bar 39 blocks and limits the two right-angled sides of the rear side of the pallet 2, ensuring that the pallet 2 is within the clamping range of the clamping mechanism, which further ensures the clamping effect. When it is necessary to retract the empty pallet 2, the electric push rod 38 retracts, driving the positioning stop bar 39 to move away from the through hole 40 and away from the support plate 9, thus achieving the blocking effect of the positioning stop bar 39 on the rear side of the pallet 2.

[0046] Furthermore, the rear soft bag conveyor includes a belt conveyor 10 with its upper conveying end faces flush with each other and a transition plate 45. The rear ends of the transition plate 45 are rotatably connected to the front ends of the belt conveyor 10. A first motor 47 is installed on one side of the front end of the belt conveyor 10 to drive the transition plate 45 to rotate up and down around the width of the belt conveyor 10. The transition plate 45 is located between the rear end of the front soft bag conveyor 7 and the front end of the belt conveyor 10. Several rollers 44 that rotate around the width of the belt conveyor 10 are rotatably connected in the middle of the transition plate 45. The rollers 44 are arranged sequentially along the conveying direction of the belt conveyor 10.

[0047] As described above, when there are no infusion bags on the current soft bag conveyor 7, the first motor 47 drives the transition plate 45 to flip upwards and position it above the front end of the belt conveyor 10. This prevents interference between the transition plate 45 and the turntable 1, the front soft bag conveyor 7, and the support plate 9 when the turntable 1 flips. When the turntable 1 flips 180° forward and the tray 2 places the infusion bag upside down on the front soft bag conveyor 7, the front soft bag conveyor 7 and the first motor 47 start. The first motor 47 drives the transition plate 45 to flip downwards towards the front soft bag conveyor 7. The upper conveying end face of the transition plate 45 is flush with the upper conveying end faces of the front soft bag conveyor 7 and the belt conveyor 10. The infusion soft bag is conveyed to the transition plate 45 from the rear end of the front soft bag conveyor 7 and then to the belt conveyor 10. This prevents the infusion soft bag from falling out of the gap between the rear end of the front soft bag conveyor 7 and the front end of the belt conveyor 10, thus ensuring the efficiency of bag unloading and conveying. By setting rollers 44, the friction between the infusion soft bag and the transition plate 45 is reduced, making it easier for the infusion soft bag to be conveyed to the belt conveyor 10.

[0048] Furthermore, the flipping mechanism includes a second motor 41, two rotating shafts 42, and two support frames 43, each arranged in an inverted U-shape. One end of each of the two rotating shafts 42 is fixedly connected to the other two sides of the rotating box 1. The rotating shafts 42 are located between the front soft bag conveyor 7 and the support plate 9. The rotating box 1 is located between the front and rear ends of the front soft bag conveyor 7. The other end of the rotating shaft 42 is rotatably connected to the horizontal section of the support frame 43 through a bearing. The drive end of the second motor 41 is connected to the other end of one of the rotating shafts 42. The range of rotation of the rotating box 1 around the rotating shaft 42 is within the range of rotation of the front soft bag conveyor 7 around the rotating shaft 42. The water tank 15 and the rear soft bag conveyor are located outside the range of rotation of the front soft bag conveyor 7 around the rotating shaft 42.

[0049] As can be seen from the above description, when the clamping mechanism clamps the two sides of the tray 2, the second motor 41 is started. The drive end of the second motor 41 rotates, driving the rotating shaft 42 to rotate, thereby driving the rotating box 1 to flip back and forth around the rotating shaft 42, which plays the role of automatically driving the rotating box 1 to flip back and forth. By setting the rotating shaft 42 between the front soft bag conveyor 7 and the support plate 9, the range of rotation of the rotating box 1 around the rotating shaft 42 is within the range of rotation of the front soft bag conveyor 7 around the rotating shaft 42. The water receiving tank 15 and the rear soft bag conveyor are located outside the range of rotation of the front soft bag conveyor 7 around the rotating shaft 42. The purpose of this setting is to avoid the rotating box 1 interfering with the rear soft bag conveyor.
