Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic tube logistics transmission, in particular to a hospital-type pneumatic tube logistics transmission device with a protective function. Background Art

[0002] The hospital pneumatic logistics transmission system is a logistics transmission system formed by closely connecting various units in the building through multiple dedicated pipelines. It uses compressed air as a power source to transport the items to be transported in the pipeline. In order to facilitate the sending and receiving of items, the pipeline of the sending and receiving station is set as a vertical pipeline, and the sending and receiving station is set in the vertical pipeline to facilitate the placement of items into the sending and receiving station or the removal of items received by the sending and receiving station.

[0003] The current pneumatic logistics transmission device with a protective function, such as patent No. 202320717468.7, discloses a pneumatic logistics transmission device with a protective function, including a supporting body, a storage plate and a rotating plate rotatably connected in the supporting body, a first connecting tube fixedly connected between the storage plate and the rotating plate, and a plurality of surrounding plates, wherein a buffer plate is slidably connected in the plurality of surrounding plates, a spring is fixedly connected to the bottom surface of the buffer plate, and the other end of the spring is fixedly connected to the upper surface of the storage plate, and a clearance hole is opened through the upper surface of the buffer plate. The structure arranges a buffer plate in the surrounding plate, and a spring is arranged on the bottom surface of the buffer plate, so that when the transmission bottle is transported to the surrounding plate, the buffer plate cooperates with the spring to buffer the transmission bottle, reduce the impact force of the transmission bottle, protect the transmission bottle and the device as a whole, and avoid damage caused by excessive impact force.

[0004] However, in this structure, the storage plate includes two forms, namely, a first connecting tube and multiple groups of surrounding plates. When the transmission bottle needs to be transported to the lower system tube, the upper system tube, the first connecting tube, the second connecting tube and the lower system tube need to be aligned up and down to ensure the transportation process; when the transmission bottle stored in the surrounding plate is transported downward, since the opening area of ​​the clearance hole on the buffer plate must be smaller than the cross-section of the bottom of the transmission bottle to play a shock-absorbing and protective role, the transmission bottle cannot be directly transported to the lower system tube from the clearance hole, and it is necessary to use a lifting piece to lift the transmission bottle into the upper system tube, and then use the first connecting tube and the second connecting tube to align up and down and transport it to the lower system tube. The whole transmission process is relatively complicated, which affects the transmission efficiency. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a hospital-type pneumatic tube logistics transmission device with a protective function to simplify the material feeding process and improve the technical effect of transmission efficiency.

[0006] To achieve this technical purpose, the utility model adopts the following scheme:

[0007] A hospital-type pneumatic logistics transmission device with a protective function comprises a support frame, the top of the support frame is connected to an upper system pipe, and the bottom is connected to a lower system pipe. The support frame is divided into an upper and lower part by a partition plate erected inside. The upper part of the support frame is rotatably connected to a transfer frame, and the lower part of the support frame is rotatably connected to a connecting pipe. The transfer frame comprises a top plate and a bottom plate. The top plate and the bottom plate are respectively provided with a plurality of through holes in the upper and lower parts. A surrounding plate group is respectively arranged between the top plate and the bottom plate corresponding to each group of through holes, and each group has two surrounding plates, and a material passing channel is formed between the two surrounding plates; a plurality of blocking mechanisms are arranged between the two surrounding plates of the same group; a fixing ring is respectively arranged on the bottom plate corresponding to each through hole thereon, and a buffer mechanism is arranged inside the fixing ring, and the aperture of the give-way hole in the center of the buffer mechanism is variable.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] The utility model discloses a novel transmission bottle, in the process of transmitting the transmission bottle, the transmission bottle is aligned and unloaded by the blocking mechanism in the fixed hole during the falling process, so as to reduce the force of the transmission bottle falling on the bottom plate, and at the same time, the transmission bottle is buffered and damped by reducing the aperture of the central giving hole of the buffer mechanism. After the transmission bottle is buffered and damped, the aperture of the central giving hole of the buffer mechanism is enlarged, so that the transmission bottle can pass through the through hole on the bottom plate without any hindrance and enter the connecting pipe for unloading, thus avoiding the problem in the prior art that the transmission bottle cannot pass smoothly due to the small diameter of the hole on the buffer plate. The transmission bottle is not lifted to the upper system pipe and then re-enters the connecting pipe for unloading, which improves the unloading effect, enhances the transmission efficiency and is convenient to use.

[0010] Further, the preferred embodiment of the present invention is:

[0011] The blocking mechanism comprises an enclosure and spring pieces. The two ends of the enclosure are respectively connected with two surrounding plates of the same group. A plurality of spring pieces are arranged inside the enclosure in a downwardly inclined manner.

[0013] The buffer mechanism comprises a sealing ring and an air pipe. A cavity is arranged inside the sealing ring, the cavity is communicated with the air pipe, and a plunger is arranged at one end of the air inlet of the air pipe.

[0014] The sealing ring is made of HNBR hydrogenated nitrile rubber.

[0015] A driving motor 1 is installed on the top of the support frame, and an output end of the driving motor 1 is fixed to the top plate.

[0016] The two ends of the connecting pipe are respectively fixedly connected with movable plates, the movable plate at the upper part of the connecting pipe is rotatably connected with the partition plate, and a driving motor 2 is arranged at the bottom of the supporting frame, and the output end of the driving motor 2 is fixedly connected with the movable plate at the lower part of the connecting pipe.

DETAILED DESCRIPTION

[0022] In order to fully understand the purpose, features and effects of the present invention, the present invention is described in detail through the following specific implementation methods, but the present invention is not limited thereto.

[0023] like Figures 1 to 4 As shown, a pneumatic tube transport device for hospitals with protective functions includes a support frame 1, which is composed of an upper plate 101, a lower plate 102, and a support rod 103. The support rod 103 is placed between the upper plate 101 and the lower plate 102. The upper plate 101 and the lower plate 102 are respectively provided with connection holes. The upper plate 101 is connected to the upper system pipe 3 through the connection holes, and the lower plate 102 is connected to the lower system pipe 4 through the connection holes. A partition plate 2 is fixedly connected to the middle of the support rod 103. The partition plate 2 divides the support frame 1 into upper and lower parts, and a material passing through hole 18 is provided on the partition plate 2.

[0024] The upper part of the support frame 1 is rotatably connected to the transfer frame, and the lower part of the support frame 1 is rotatably connected to the connecting pipe 20. The transfer frame is composed of a top plate 5 and a bottom plate 7. A drive motor 8 is installed on the upper plate 101 of the support frame 1. The output end of the drive motor 8 is fixed to the top plate 5. The drive motor 8 drives the transfer frame to rotate as a whole by driving the top plate 5.

[0025] A plurality of through holes 9 are respectively provided on the top plate 5 and the bottom plate 7 of the transfer rack in the circumferential direction around the rotation center of the transfer rack, and the upper and lower through holes 9 are arranged in one-to-one correspondence. A surrounding plate group is arranged at the position corresponding to the through holes between the top plate 5 and the bottom plate 7, and each group consists of two surrounding plates 6. A material transfer channel is formed between the two surrounding plates 6 in the same group.

[0026] Several groups of blocking mechanisms are vertically arranged between the two surrounding plates 6 of the same group. The blocking mechanism consists of an enclosure 10 and a spring sheet 11. The enclosure 10 is placed between the two surrounding plates 6 and the two ends of the enclosure 10 are respectively fixedly connected to the surrounding plates 6 corresponding to one end of each. Several spring sheets 11 are arranged at intervals on the inner wall of the enclosure 10. One end of the spring sheet 11 is fixedly connected to the enclosure 10, and the other end is tilted downward by the enclosure 10 toward one side of the bottom plate 7. By tilting the spring sheet 11 downward, the falling transmission bottle can be unloaded.

[0027] In order to prevent the end of the spring piece 11 from being too sharp and scratching the transmission bottle, a silicone pad 12 is provided at the end of the spring piece 11. The silicone pad 12 can also increase the friction between the spring piece 11 and the transmission bottle, thereby improving the blocking effect of the spring piece 11 on the transmission bottle.

[0028] A fixing ring 13 is also provided on the upper surface of the bottom plate 7 at the position corresponding to each through hole of the bottom plate 7, and a buffer mechanism is installed in each fixing ring 13, which is composed of a sealing ring 14 and an air pipe 16. The sealing ring 14 is placed on the inner wall of the fixing ring 13, and a cavity 15 is provided inside the sealing ring 14. The cavity 15 is connected to the air outlet of the air pipe 16, and a plunger 17 is provided at the air inlet of the air pipe 16. In this embodiment, the sealing ring 14 is made of HNBR hydrogenated nitrile rubber, which has excellent corrosion resistance, tear resistance and compression deformation resistance. The sealing ring 14 is inflated or deflated through the air pipe 16, so that the cross-section of the clearance hole in the center of the sealing ring 14 becomes smaller or larger, so as to achieve the purpose of buffering or letting the transmission bottle pass.

[0029] In this embodiment, the upper and lower ends of the connecting tube 20 are respectively fixedly connected with the movable plate 19, and a rotating shaft 22 is installed at the bottom center position of the partition plate 2, and the movable plate 19 at the upper end of the connecting tube 20 is rotatably connected with the rotating shaft 20; a driving motor 21 is installed at the bottom of the lower plate 102 of the support frame 1, and the output end of the driving motor 21 is fixed to the movable plate 19 at the lower end of the connecting tube 20, and the driving motor 21 drives the connecting tube 20 to rotate through the movable plate 19.

[0030] When the device is in use, when the relevant personnel send and receive the transmission bottle, the driving motor 8 drives the transfer frame to rotate as a whole, so that a through hole 9 on the top plate 5 is aligned with the upper system tube 3. When loading, the transmission bottle is sent to the bottom plate 7 through the upper system tube 3. When the transmission bottle falls, the inclined spring piece 11 is used to unload the force of the transmission bottle in the falling process, so as to reduce the force of the transmission bottle falling on the bottom plate 7. At the same time, the plunger 17 is opened to inject gas into the air pipe 16 until the gas enters the cavity 15 to expand the sealing ring 14. The cross-sectional area of ​​the through hole in the center of the expanded sealing ring 14 is smaller than the cross-sectional area of ​​the bottom of the transmission bottle. The transmission bottle falls on the sealing ring 14. Since the sealing ring 14 has a certain elasticity, it can play a certain buffering and shock-absorbing role on the transmission bottle.

[0031] Repeat the above process to complete the loading of all the material transfer channels in the transfer rack;

[0032] The driving motor 21 drives the connecting tube 20 to rotate to the bottom of the material passing through hole 18, so that the top of the connecting tube 20 is aligned with a through hole 9 of the bottom plate 7, and then the sealing ring 14 above the through hole 9 is deflated, so that the transmission bottle can enter the connecting tube 20 without hindrance, and then the driving motor 21 drives the connecting tube 20 to rotate to the top of the lower system tube 4, and the connecting tube 20 is aligned with the lower system tube 4 before unloading; while the connecting tube 20 is unloading, the upper system tube 3 can also be used to receive another bottle of transmission bottle.

[0033] In this embodiment, the fan providing power is connected to the upper system pipe, and the movement of the transmission bottle is controlled by the air flow speed.

[0034] The utility model can easily cause damage to the transmission bottle if it falls directly onto the bottom plate when the transmission bottle is being transported. By arranging the inclined spring piece, the force of the transmission bottle in the falling process can be unloaded, and the force of the transmission bottle falling onto the bottom plate can be reduced. At the same time, the plunger can be opened to inject gas into the air pipe until the gas enters the cavity to expand the sealing ring, so that it has a certain elasticity, thereby playing a buffering and shock-absorbing role for the transmission bottle. After the transmission bottle is buffered and shock-absorbed, the sealing ring is reduced by degassing, so that the transmission bottle can enter the connecting pipe through the through hole on the bottom plate without hindrance for unloading, avoiding the inability of the existing device to pass smoothly due to the small holes opened on the elastic buffer plate, thereby improving the unloading effect, enhancing the transmission efficiency, and facilitating use.

[0035] Finally, it should be noted that the above-listed examples are only preferred embodiments of the present invention. Of course, those skilled in the art can make changes and modifications to the present invention. If these modifications and modifications fall within the scope of the claims of the present invention and their equivalent technologies, they should be considered to be within the scope of protection of the present invention.
