Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipeline logistics system, in particular to a pneumatic pipeline logistics system for medical environment. BACKGROUND

[0002] The pneumatic pipeline logistics transmission system is composed of an air compressor, a pipeline and a pipeline reverser, and its basic use is to transmit articles, and its working principle is that the air compressor extracts and compresses air as power, and the pneumatic pipeline logistics system for medical environment is a combination of advanced modern communication technology and mechatronics technology, which closely connects various departments of a hospital, such as outpatient service, medicine, operating room, laboratory, blood bank, medical technology, inpatient department, and central supply room, through a special pipeline.

[0003] The system is rapid and efficient in transmission, and can quickly transmit samples to a designated location to realize one-to-one and point-to-point reliable transmission. However, since the transmission is driven by compressed air, the transmission bottle makes accelerated or high-speed motion in the transmission pipe, so if no measures are taken to slow down the transmission bottle at the tail end of transmission, high-speed impact may occur, resulting in damage to sample quality, index parameters, etc. To solve the above problems, the prior art often uses reverse blowing, air resistance, and rotary deceleration to achieve deceleration of the transmission bottle. However, the transmission bottle has different masses and different transmission speeds in the pipeline, and there are cases where the air resistance is too large for the transmission bottle to slide out of the pipeline, or the air resistance is insufficient for the transmission bottle to be ejected from the pipeline. If the speed of the transmission bottle is to be controlled to control the air resistance, there are problems of complex construction, high cost, and complex control. Therefore, there is an urgent need for a pneumatic pipeline logistics system for medical environment that can solve the above problems. SUMMARY

[0007] The further improved scheme in the technical scheme is as follows:

[0008] 1. In the scheme, the first buffer comprises an arc-shaped buffer plate, guide rods located on the opposite sides of the arc-shaped buffer plate, and a first spring sleeved on the outer wall of the guide rod, a first through hole is arranged on one side of the connecting plate relative to the arc-shaped buffer plate, the guide rod is slidably installed in the first through hole, and the first spring is located between the surface of the connecting plate and the surface of the arc-shaped buffer plate.

In the scheme, a first connecting chain is symmetrically arranged on one side of the arc-shaped buffer plate relative to the connecting plate and about the guide rod, a first sliding groove is symmetrically arranged on the surface of the connecting plate and about the first through hole, a guide column sleeved with a second spring is arranged in the first sliding groove, and one end of the first connecting chain away from the connecting plate is slidably sleeved on the guide column through a sliding sleeve. When the arc-shaped buffer plate approaches the connecting plate, the second spring is in a compressed state.

[0010] 3. In the scheme, a limiting plate with a second through hole is arranged on the opposite side of the two installation frames and away from one end of the transmission pipe, the second buffer further comprises a second connecting chain, a buffer block with a second through slot, and a connecting rod, one end of the second connecting chain is rotatably connected with the connecting plate, the other end can pass through the second through hole of the limiting plate and is fixedly connected with the buffer block, a rotating wheel frame with a rotating wheel is arranged on one side of the buffer block relative to the outlet end of the transmission pipe, a curved elastic sheet is arranged on each side of the rotating wheel frame, a plug rod is fixedly connected to one side of the rotating wheel frame away from the rotating wheel and is slidably installed in the second through slot, a stop plate is arranged on one end of the plug rod away from the rotating wheel frame, when the stop plate is in contact with the surface of the buffer block, the elastic sheet is in a natural state, and when the stop plate is separated from the buffer block, the rotating wheel frame presses the two elastic sheets to make them bend away from each other.

[0011] 4. In the scheme, a third spring is sleeved on the connecting rod between the limiting plate and the second connecting chain.

[0012] 5. In the above scheme, each of the two mounting brackets is provided with a plug plate with a socket on the opposite side.

[0015] 8. In the above scheme, the center of the arc-shaped rod coincides with the shaft hole.

[0016] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0017] This invention relates to a pneumatic pipeline logistics system for medical environments. The distance between the arc-shaped buffer plates is smaller than the size of the transport bottle. The transport bottle first compresses the arc-shaped buffer plates on both sides, causing them to approach the connecting plate and compress the first and second springs. This also pushes the connecting plate to move in opposite directions, compressing the third and fourth springs. During the contact phase between the transport bottle and the arc-shaped buffer plates, the system needs to overcome the deformation of the first, second, third, and fourth springs, significantly improving the overall buffering and energy storage performance. Furthermore, under the force of the first, second, third, and fourth springs, the arc-shaped buffer plates collectively form a clamping force on both sides of the transport bottle and rub against the sides of the bottle, achieving initial deceleration and buffering of the transport bottle. Simultaneously, the rotation of the connecting plate drives the buffer blocks to move in opposite directions, making the distance between the two buffer blocks smaller than the size of the transfer bottle. As the transfer bottle continues to move, it will come into contact with the rotating wheel in the forward direction, thus pushing the rotating wheel frame to move away from the transfer tube. During the movement of the rotating wheel frame, the elastic sheet will bend and deform in opposite directions. The transfer bottle then needs to do work to overcome the deformation of the elastic sheet, thereby achieving deceleration and buffering of the transfer bottle again. It also provides buffer displacement space, effectively avoiding material damage caused by sudden stopping of the transfer bottle. This achieves multi-stage buffering of the transfer bottle, thus adapting to the buffering needs of transfer bottles of different masses and speeds. Furthermore, it buffers the transfer bottle in two directions simultaneously, further improving the overall buffering performance. Attached Figure Description

Therefore, they should not be construed as limitations on the invention. The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this patent based on the specific circumstances.

[0026] Example 1: A pneumatic pipeline logistics system for medical environments includes: several transceiver stations 1, a multi-directional converter 2, an air direction converter 3, and a power source 4 connected to the air direction converter 3. The multi-directional converter 2 on the transmission pipe 5 is located between the several transceiver stations 1 and a buffer mechanism 6. The air direction converter 3 and the buffer mechanism 6 are provided with an air blowing transmission pipe 7 and an air suction transmission pipe 8 in parallel. The transceiver station 1 is connected to at least two transmission pipes 5.

[0027] A mounting bracket 9 with a first through groove 10 is symmetrically arranged at the outlet end of the transmission pipe 5. The mounting bracket 9 has a shaft hole 11 for a connecting plate 12 mounted in the first through groove 10 to rotate and hinge. A first buffer 13 is arranged on each of the two connecting plates 12, with one end closer to the transmission pipe 5 and the other end farther from the transmission pipe 5, and a second buffer 14 is arranged on each end. When the transmission bottle from the transmission pipe 5 does not contact the first buffer 13, the distance between the two first buffers 13 is less than the size of the transmission bottle, and the distance between the two second buffers 14 is greater than the size of the transmission bottle. When the transmission bottle presses against the first buffer 13, the ends of the two connecting plates 12 with the first buffer 13 move away from each other, and the other ends with the second buffer 14 move towards each other. The movement causes the distance between the two second buffers 14 to be less than the size of the transmission bottle. When the transmission bottle reaches the outlet end of the transmission tube 5, the distance between the first buffers 13 of the connecting plate 12 is less than the size of the transmission bottle. As a result, the transmission bottle will come into contact with the first buffers 13. Under the action of the transmission bottle, the two first buffers 13 move in opposite directions. The transmission bottle will have to overcome the deformation of the first buffers 13, which will buffer the transmission bottle and reduce its speed. At the same time, the end of the connecting plate with the second buffers 14 moves towards each other. The transmission bottle needs to do work to overcome the deformation of the second buffers 14, which will reduce the speed of the transmission bottle and prevent it from having a strong collision with the receiving end, which would damage the transmission bottle.

[0028] The first buffer component 13 includes an arc-shaped buffer plate 15, a guide rod 16 located on the opposite side of the arc-shaped buffer plate 15, and a first spring 19 fitted on the outer wall of the guide rod 16. A first through hole 18 is provided on one side of the connecting plate 12 relative to the arc-shaped buffer plate 15, allowing the guide rod 16 to be inserted and slidably installed. The first spring 19 is located between the surface of the connecting plate 12 and the surface of the arc-shaped buffer plate 15. A first connecting chain 17 is symmetrically arranged on one side of the arc-shaped buffer plate 15 relative to the connecting plate 12 and about the guide rod 16. A first groove 20 is symmetrically arranged on the surface of the connecting plate 12 about the first through hole 18. A guide post 22 fitted with a second spring 21 is provided in the first groove 20. The end of the first connecting chain 17 away from the connecting plate 12 can slide on the guide post 22 via a sliding sleeve 23. When the arc-shaped buffer plate 15 approaches the connecting plate 12, the second spring 21 is compressed. During the movement of the transfer bottle, the two springs are compressed. The arc-shaped buffer plates 15 move in opposite directions. During their movement, the arc-shaped buffer plates 15 drive the guide rod 16 to slide within the first through hole 18, simultaneously compressing the first spring 19. This forces the transfer bottle to overcome the deformation of the first spring 19 and perform work. At the same time, during the movement of the first buffer member 13 in opposite directions, the first connecting chain 17 moves towards each other. Consequently, the sliding sleeve 23 of the first connecting chain 17 slides towards each other within the guide rod 16, compressing the second spring 21 and causing it to deform and store energy. This forces the transfer bottle to overcome the deformation of the second spring 21 and perform work, which again provides a buffering effect for the transfer bottle. In summary, when the transfer bottle contacts the first buffer member, and during its movement, it needs to overcome the deformation of both the first spring 19 and the second spring 21, which can provide a buffering and deceleration effect. This can provide initial buffering for the transfer bottle, reducing its speed and greatly improving the energy storage performance of the first buffer member, thus expanding its elastic limit.

[0029] Located on opposite sides of the two mounting brackets 9, and at the end furthest from the transmission pipe 5, are respectively a limiting plate 27 with a second through hole 28. The second buffer member 14 further includes a second connecting chain 29, a buffer block 31 with a second through groove 30, and a connecting rod 32. One end of the second connecting chain 29 is rotatably connected to the connecting plate 12, and the other end can pass through the second through hole 28 of the limiting plate 27 and be fixedly connected to the buffer block 31. A third spring 33 is provided between the limiting plate 27 and the second connecting chain 29 and fitted on the connecting rod 32. A wheel frame 34 with a rotating wheel 35 is provided on one side of the buffer block 31 opposite to the outlet end of the transmission pipe 5. A bent elastic sheet 36 is provided on each side of the wheel frame 34. A sliding insertion rod 37 is fixedly connected to one side of the rotating wheel 35 and extends into the second through groove 30. The end of the insertion rod 37 away from the rotating wheel frame 34 is provided with a stop plate 38. When the stop plate 38 contacts the surface of the buffer block 31, the elastic sheet 36 is in its natural state. When the stop block 38 separates from the buffer block 31, the rotating wheel frame 34 squeezes the two elastic sheets 36 so that they bend and unfold in opposite directions, so that the connecting plate 12 hinges the second buffer member 14 and moves towards the center of the transmission tube 5, that is, pushes the buffer block 31 to move towards each other. Then, as the transmission bottle continues to move, the transmission bottle will contact the rotating wheel 35 on the buffer block 31. The rotating wheel 35 is squeezed by the transmission bottle, so that the rotating wheel frame 34 moves to squeeze the elastic sheet 36.

[0030] The connecting plate 12 is provided with a slope 43 on one side surface relative to the arc-shaped buffer plate 15. The extension directions of the two slopes 43 can intersect the axial section of the transmission pipe 5. The slope 43 is parallel to the arc-shaped buffer plate 15, which facilitates the transmission of force between the arc-shaped buffer plate 15 and the connecting plate 12 and avoids the situation where the connecting plate 12 is easily broken due to uneven force between the arc-shaped buffer plate 15 and the connecting plate 12.

[0031] The aforementioned second connecting chain 29 further includes a second connecting frame 45 fixedly installed on the connecting plate 12, a connecting seat 47 fixedly connected to one end of the connecting rod 32, and a second movable plate 46 disposed between the second connecting frame 45 and the connecting seat 47. The second movable plate 46 is rotatably connected to the second connecting frame 45 and the connecting seat 47 respectively, and a movable space is left between the connecting rod 32 and the connecting plate 12 to accommodate the rotation of the connecting plate 12 around the shaft hole 11 to ensure the reliability of force transmission between the connecting plate 12 and the connecting rod 32.

[0032] The aforementioned first connecting chain 17 further includes a first connecting frame 24 fixedly installed on the arc-shaped buffer plate 15, and a first movable plate 26 disposed between the sliding sleeve 23 and the first connecting frame 24. The first movable plate 26 is rotatably connected to the first connecting frame 24 and the sliding sleeve 23 respectively, and can adapt to the squeezing force of the transmission bottle on the arc-shaped buffer plate 15 to rotate, thereby allowing the sliding sleeve 23 to slide on the guide post 22 to realize the compression and release of the second spring 21.

[0033] Example 2: A pneumatic pipeline logistics system for medical environments includes: several transceiver stations 1, a multi-directional converter 2, an air direction converter 3, and a power source 4 connected to the air direction converter 3. The multi-directional converter 2 on the transmission pipe 5 is located between the several transceiver stations 1 and a buffer mechanism 6. The air direction converter 3 and the buffer mechanism 6 are provided with an air blowing transmission pipe 7 and an air suction transmission pipe 8 in parallel. The transceiver station 1 is connected to at least two transmission pipes 5.

[0034] A mounting bracket 9 with a first through groove 10 is symmetrically arranged at the outlet end of the transmission pipe 5. The mounting bracket 9 has a shaft hole 11 for a connecting plate 12 installed in the first through groove 10 to rotate and hinge. A first buffer 13 is arranged on the opposite side of the two connecting plates 12, at the end close to the transmission pipe 5, and a second buffer 14 is arranged on the end away from the transmission pipe 5. When the transmission bottle delivered by the transmission pipe 5 does not contact the first buffer 13, the distance between the two first buffers 13 is less than the size of the transmission bottle, and the distance between the two second buffers 14 is greater than the size of the transmission bottle. When the transmission bottle squeezes the first buffer 13, the ends of the two connecting plates 12 with the first buffer 13 move away from each other, and the other ends with the second buffer 14 move towards each other, so that the distance between the two second buffers 14 is less than the size of the transmission bottle.

[0035] The first buffer component 13 includes an arc-shaped buffer plate 15, a guide rod 16 located on the opposite side of the arc-shaped buffer plate 15, and a first spring 19 fitted on the outer wall of the guide rod 16. The connecting plate 12 is provided with a first through hole 18 on one side of the arc-shaped buffer plate 15 for the guide rod 16 to be inserted and slidably installed, and the first spring 19 is located between the surface of the connecting plate 12 and the surface of the arc-shaped buffer plate 15.

[0036] Located on opposite sides of the two mounting brackets 9, and at the end furthest from the transmission pipe 5, are respectively a limiting plate 27 with a second through hole 28. The aforementioned second buffer member 14 further includes a second connecting chain 29, a buffer block 31 with a second through groove 30, and a connecting rod 32. One end of the second connecting chain 29 is rotatably connected to the connecting plate 12, and the other end can pass through the second through hole 28 of the limiting plate 27 and be fixedly connected to the buffer block 31. Between the limiting plate 27 and the second connecting chain 29 and fitted onto the connecting rod 32, there is a first... Three springs 33, the buffer block 31 is provided with a rotating frame 34 with a rotating wheel 35 on one side of the side opposite to the outlet end of the transmission pipe 5. A bent elastic sheet 36 is provided on each side of the rotating frame 34. A sliding insertion rod 37 extending into the second through groove 30 is fixedly connected to the side of the rotating frame 34 opposite to the rotating wheel 35. A stop plate 38 is provided at the end of the insertion rod 37 away from the rotating frame 34. When the stop plate 38 contacts the surface of the buffer block 31, the elastic sheet 36 is in its natural state. When the stop block 38 separates from the buffer block 31, the aforementioned rotating frame 34 presses the two elastic plates 36 so that they bend and unfold in opposite directions. Under the pressure of the transmission bottle, the connecting plate 12 rotates. While pressing the first spring 19, the second spring 21, and the third spring 33 to store energy and buffer, the connecting plate 12 hinges the second buffer member 14 and moves towards the center of the transmission tube 5, that is, pushes the buffer block 31 to move towards each other. Then, as the transmission bottle continues to move, the transmission bottle will contact the rotating wheel 35 on the buffer block 31. The rotating wheel 35 is pressed by the transmission bottle, causing the rotating frame 34 to move and press the elastic plate 36. This causes the elastic plate 36 to deform. The transmission bottle needs to overcome the deformation of the elastic plate 36 to do work. In this way, the elastic plate 36 can buffer and decelerate the transmission bottle. At the same time as the elastic plate 36 deforms, the movement of the rotating frame 34 also provides a buffer distance for the transmission bottle. This reduces the speed of the transmission bottle and prevents it from having a strong collision with the receiving end, which could damage the transmission bottle.

[0037] When the transfer bottle moves to the point where it separates from the first buffer 13 of the connecting plate 12, the connecting plate 12 loses its function of transferring the bottle. Under the action of the third spring 33, the connecting plate 12 reverses and resets, causing one end of the connecting plate 12 with the buffer block 31 to move in opposite directions. The connecting plate 12 rotates around the axis, causing the other end of the connecting plate 12 with the arc-shaped buffer plate 15 to return to its original position. The distance between the arc-shaped buffer plates 15 is kept smaller than the size of the transfer bottle, and the distance between the two buffer blocks 31 is larger than the size of the transfer bottle. In this way, the transfer bottle can pass smoothly between the two buffer blocks 31.

[0038] The aforementioned first connecting chain 17 further includes a first connecting frame 24 fixedly installed on the arc-shaped buffer plate 15, and a first movable plate 26 disposed between the sliding sleeve 23 and the first connecting frame 24. The first movable plate 26 is rotatably connected to the first connecting frame 24 and the sliding sleeve 23 respectively, and can adapt to the squeezing force of the transmission bottle on the arc-shaped buffer plate 15 to rotate, thereby allowing the sliding sleeve 23 to slide on the guide post 22 to realize the compression and release of the second spring 21.

[0039] On the opposite sides of the two mounting brackets 9, there is a plate 40 with a socket 39. The extension direction of the two plates 40 is on the same straight line as the shaft hole 11. On the opposite sides of the connecting plate 12, there is an arc-shaped rod 42 fitted with a fourth spring 41. When the end of the arc-shaped rod 42 away from the connecting plate 12 is inserted into the socket 39, the fourth spring 41 is in a compressed state. The center of the arc-shaped rod 42 coincides with the shaft hole 11. During the rotation of the connecting plate 12 around the shaft, the arc-shaped rod 42 can rotate around the shaft hole 11, ensuring that the end away from the connecting plate can be inserted into the socket 39. As the distance of the moving plates 12 increases, the distance of the arc rod 42 passing through the insertion hole 39 also increases. At the same time, the deformation and compression of the fourth spring 41 means that the transmission bottle needs to overcome the deformation of the fourth spring 41 to further buffer the transmission bottle. In summary, during the contact stage with the first buffer 13 and during its movement, the transmission bottle needs to overcome the deformation of the first spring 19, the second spring 21, the third spring 33 and the fourth spring 41. Meanwhile, the arc buffer plate 15 has a reaction force on the transmission bottle, which enables the transmission bottle to decelerate and buffer, and also greatly improves the overall buffering and energy storage performance.

[0040] The working principle is as follows: The transfer bottle is conveyed in the transfer pipe of the pipeline logistics transfer system. When the transfer bottle is conveyed to the outlet end of the transfer pipe 5, the distance between the arc-shaped buffer plates of the connecting plate 12 is smaller than the size of the transfer bottle. Thus, the transfer bottle will come into contact with the arc-shaped buffer plate 15, which will move closer to the connecting plate 12 and simultaneously compress the first spring 19. At the same time, the sliding sleeve 23 of the first hinge 17 will slide on the guide post 22, compressing the second spring 21. Under the action of the transfer bottle, the connecting plate 12 moves in opposite directions. During the rotation of the connecting plate 12, the arc-shaped rod 42 is driven to embed into the insertion hole, thereby compressing the fourth spring 41. Furthermore, the rotation of the connecting plate 12 around its axis will compress the third spring 33. Therefore, during the contact process between the transfer bottle and the arc-shaped buffer plate 12, the transfer bottle will overcome the forces of the first spring 19 and the second spring 21. The third spring 33 and the fourth spring 41 perform work, thus buffering the transfer bottle and reducing its speed. Additionally, the rotation of the connecting plate 12 around its axis compresses the third spring 33, causing the buffer blocks 31 on the connecting rod 32 to move towards each other. This makes the distance between the buffer blocks 31 smaller than the size of the transfer bottle, thereby stopping the transfer bottle in its forward direction. When the transfer bottle contacts the rotating wheel 35 and continues to move, it drives the rotating wheel frame 34 to move away from the transfer tube 5. During this process, the rotating wheel frame 34 compresses the elastic sheet 36, and the stop plate 38 disengages from the buffer blocks 31. The transfer bottle then overcomes the deformation of the elastic sheet 36, achieving further buffering of the transfer bottle and providing buffer displacement space to prevent a strong collision with the buffer blocks 31 that could damage the transfer bottle.

[0041] Next, as the transfer bottle continues to move and separates from the arc-shaped buffer plate 15 of the connecting plate 12, the arc-shaped buffer plate 15 loses its squeezing effect on the transfer bottle. Under the action of the third spring 33, the connecting plate 12 reverses and resets around the axis, causing the buffer blocks 31 connected to the connecting plate 12 to move in opposite directions, and the arc-shaped buffer plates 15 connected to the connecting plate 12 to move towards each other. This keeps the distance between the arc-shaped buffer plates 15 smaller than the size of the transfer bottle, and the distance between the two buffer blocks 31 larger than the size of the transfer bottle, so that the transfer bottle can pass smoothly between the two buffer blocks 31.

[0042] When using the aforementioned pneumatic pipeline logistics system for medical environments, the distance between the arc-shaped buffer plates is smaller than the size of the transfer bottle. The transfer bottle first compresses the arc-shaped buffer plates on both sides, causing them to approach the connecting plate and compress the first and second springs. This also pushes the connecting plate to move in opposite directions, compressing the third and fourth springs. Therefore, during the contact phase between the transfer bottle and the arc-shaped buffer plates, the work done by overcoming the deformation of the first, second, third, and fourth springs is required, significantly improving the overall buffering and energy storage performance. Furthermore, under the force of the first, second, third, and fourth springs, the arc-shaped buffer plates will collectively form a clamping force on both sides of the transfer bottle and rub against the sides of the transfer bottle, achieving initial deceleration and buffering of the transfer bottle. Simultaneously, the rotation of the connecting plate drives the buffer blocks to move in opposite directions, making the distance between the two buffer blocks smaller than the size of the transfer bottle. As the transfer bottle continues to move, it will come into contact with the rotating wheel in the forward direction, thus pushing the rotating wheel frame to move away from the transfer tube. During the movement of the rotating wheel frame, the elastic sheet will bend and deform in opposite directions. The transfer bottle then needs to do work to overcome the deformation of the elastic sheet, thereby achieving deceleration and buffering of the transfer bottle again. It also provides buffer displacement space, effectively avoiding material damage caused by sudden stopping of the transfer bottle. This achieves multi-stage buffering of the transfer bottle, thus adapting to the buffering needs of transfer bottles of different masses and speeds. Furthermore, it buffers the transfer bottle in two directions simultaneously, further improving the overall buffering performance.
