Description

Technical Field

[0001] This utility model relates to the field of transportation, specifically a pneumatic logistics system conversion center. Background Technology

[0002] During the normal operation of a hospital, the transportation of small materials, medicines and samples between various medical technology departments, ward nursing units, outpatient and emergency departments and management departments is quite complicated and mechanical. For this reason, the market has proposed medical material logistics systems, including different forms of logistics systems such as rail logistics systems, box logistics systems and pneumatic logistics systems.

[0003] A single pneumatic system (hereinafter referred to as a subsystem) uses a blower and a set of pipeline equipment. The compressed air generated by the blower is used as power to push the special conveying bottle in the pipeline to transport materials. Based on the principle of pneumatic propulsion, one blower can only push one conveying bottle at a time. In order to meet the needs of multiple points in the hospital for simultaneous delivery, the hospital pneumatic logistics system is composed of multiple subsystems. In order to realize the mutual transfer function of conveying bottles between the various single pneumatic systems, a conversion center is set up to connect multiple subsystems in parallel. This configuration has become the mainstream configuration of the current hospital pneumatic logistics system.

[0004] However, the current hospital pneumatic tube system's conversion center adopts a single-station conversion design. The next conversion process can only continue after the entire receiving-conversion-transmission process is completed. The receiving and transmission processes are affected by subsystems, and the entire conversion process is not continuous. When the subsystem is busy, the conversion center will stop and wait, resulting in low efficiency and long waiting time for delivery bottles. Therefore, a high-efficiency conversion center with a buffer station is needed to solve the problem of the conversion center being stuck in the receiving and transmission stages. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a pneumatic logistics system conversion center.

[0006] The specific technical solution is as follows: A pneumatic fluid system conversion center includes multiple inlet pipes and multiple outlet pipes. The multiple inlet pipes are arranged in a ring, and the multiple outlet pipes are also arranged in a ring. The diameter of the multiple inlet pipes arranged in a ring is the same as the diameter of the multiple outlet pipes arranged in a ring. Each inlet pipe is provided with a switch unit at its lower part for controlling the opening or closing of the lower part of the inlet pipe. Multiple conversion units are also provided in a ring between the inlet pipes and the outlet pipes. The diameter of the multiple conversion units arranged in a ring is the same as the diameter of the inlet pipes arranged in a ring. The multiple conversion units are mounted on a rotating plate. The rotating plate is provided with a first motor at its lower part to drive the rotating plate to rotate. Each conversion unit includes a conversion tube, and the lower part of each conversion tube is also provided with a corresponding switch unit for controlling the opening or closing of the lower part of the conversion tube. Driven by the rotating plate, each conversion tube can rotate to be below any inlet pipe to connect with the inlet pipe, and each conversion tube can also rotate to be above any outlet pipe to connect with the outlet pipe.

[0007] Furthermore, there is a buffer unit between the inlet pipe and the conversion unit. The number of buffer units is the same as the number of inlet pipes and they correspond one-to-one. The buffer unit includes a buffer tube, the upper part of which is connected to the lower part of the corresponding inlet pipe. The lower part of the buffer tube is also provided with a switch unit for controlling the lower part of the buffer tube to open or close.

[0008] Furthermore, the switching unit includes a base plate, a cover plate, a crank, a baffle, and a second motor. Both the base plate and the cover plate have holes with the same diameter as the pipeline. The base plate and the cover plate form a cavity. The baffle is located in the cavity and can slide within the cavity. By sliding the baffle within the cavity, the holes on the base plate and the cover plate can be closed or opened accordingly. The baffle has a straight groove. The shaft end of the second motor is connected to one end of the crank, and the other end of the crank is connected to the straight groove of the baffle. The second motor drives the crank to rotate, thereby causing the baffle to reciprocate within the cavity.

[0009] Furthermore, the conversion unit also includes an upper connecting plate, which is fixedly connected to the switch unit by a support rod. The top surface of the conversion tube is at the same height as the upper connecting plate. The upper connecting plate is also provided with holes at the corresponding positions of the conversion tube, and a sealing ring is provided at the corresponding hole.

[0010] Furthermore, it also includes a first fixed platform and a second fixed platform. The first fixed platform is fixed above the second fixed platform. A plurality of the inlet pipes are installed on the upper part of the first fixed platform, and a plurality of the outlet pipes are installed on the lower part of the second fixed platform. The rotating plate is installed on the upper part of the second fixed platform, and a first gear is provided on the lower part of the rotating plate. A second gear is connected to the output shaft of the first motor, and the first gear and the second gear mesh.

[0011] Furthermore, it also includes a third fixed platform, which is located between the first fixed platform and the second fixed platform, and the cache unit is disposed on the third fixed platform.

[0012] Furthermore, there is at least one third fixed platform, and each third fixed platform is provided with a buffer unit that is the same number as the number of inlet pipes and whose positions correspond one-to-one.

[0013] Furthermore, the number of the inlet pipe, the outlet pipe, and the buffer pipe are all 6 and distributed at equal angles. The outer contours of the first fixed platform, the second fixed platform, and the third fixed platform are all regular hexagons. The hexagonal positions of the first fixed platform and the hexagonal positions of the third fixed platform are fixedly connected by a support frame. The third fixed platform and the second fixed platform are also fixedly connected by a support frame.

[0014] Furthermore, sensors are provided on the sides of the inlet pipe, the conversion pipe, the buffer pipe, and the outlet pipe to detect whether there is a delivery bottle in the corresponding pipeline.

[0015] Compared with the prior art, the technical solution proposed in this utility model sets up a rotating plate and multiple conversion units on the rotating plate. Each conversion unit can be connected to any inlet pipe and outlet pipe, which can realize the reception of multiple conveying bottles. Then, the rotating plate sequentially converts each conveying bottle to the upper part of the corresponding outlet pipe, the switch unit opens, and the conversion is completed. In addition, a buffer unit is set up so that when multiple conveying bottles are transported to the conversion center through the pipeline, they can be effectively buffered and then work in sequence, which also avoids system lag and improves conversion efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0024] To address the problems existing in the relevant prior art, this utility model proposes a pneumatic fluid system conversion center. The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0025] Example 1:

[0026] Please see Figures 1 to 2 This utility model proposes a pneumatic fluid system conversion center, including multiple inlet pipes 1 and multiple outlet pipes 2. The multiple inlet pipes 1 are arranged in a ring, and the multiple outlet pipes 2 are also arranged in a ring. The diameter of the multiple inlet pipes 1 in a ring is the same as the diameter of the multiple outlet pipes 2 in a ring. Each inlet pipe 1 is provided with a switch unit 3 at its lower part to control the opening or closing of the lower part of the inlet pipe 1. Multiple conversion units 4 are also provided in a ring between the inlet pipes 1 and the outlet pipes 2. The diameter of the multiple conversion units 4 in a ring is the same as the diameter of the inlet pipes 1 in a ring. The multiple conversion units 4 are mounted on a rotating plate 5. The rotating plate 5 is provided with a first motor 6 at its lower part to drive the rotating plate 5 to rotate. Each conversion unit 4 includes a conversion pipe 7. The conversion pipe 7 is also provided with a corresponding switch unit 3 at its lower part to control the opening or closing of the lower part of the conversion pipe 7. Driven by the rotating plate 5, each conversion pipe 7 can rotate to be below any inlet pipe 1 to connect with the inlet pipe 1, and each conversion pipe 7 can also rotate to be above any outlet pipe 2 to connect with the outlet pipe 2.

[0027] In the above scheme, the inlet pipe is connected to the front conveyor line of the conveying bottle, and the outlet pipe is connected to the rear conveyor line. The conveying bottle is transported from the front conveyor line to the conversion center, then converted to the corresponding outlet position by the conversion unit, and then transported to the designated position by the rear conveyor line. The specific conversion process is as follows:

[0028] The operator places the delivery bottle on the front-end conveyor line at the station. Under air pressure, the delivery bottle is transported from the corresponding inlet pipe to the conversion center. Then, an empty conversion unit rotates to the lower part of the inlet pipe under system control. The corresponding switch unit at the lower part of the inlet pipe then opens, and the delivery bottle falls into the conversion pipe. Then, according to the instructions issued by the system, the rotating plate rotates again, driving the conversion pipe to the upper part of the designated outlet pipe. Then, the switch unit below the rotating pipe opens, and the delivery bottle in the rotating pipe enters the outlet pipe. Finally, it is transported to the final position through the rear-end conveyor line.

[0029] Furthermore, when a front-end conveyor line needs to transport multiple bottles sequentially, whenever a bottle reaches the inlet pipe position, a rotating tube rotates to below the outlet pipe, the corresponding switch unit opens, and the bottle falls into the rotating tube. Then, the station puts in the next bottle, while another rotating tube rotates to below the inlet pipe to repeatedly receive bottles. In this way, multiple bottles can be continuously received from the same conveyor pipe, and subsequently, the control system will send the bottles to the corresponding outlet pipe positions accordingly.

[0030] It is understandable that the control procedures for pneumatic logistics are common knowledge in the field and are existing technology. During the above conversion process, those skilled in the art can set up control procedures according to specific purposes without having to make any creative effort.

[0031] Example 2

[0032] Please see Figure 3 Between the inlet pipe 1 and the conversion unit 4, there is a buffer unit 8. The number of buffer units 8 is the same as the number of inlet pipes 1 and they correspond one-to-one. The buffer unit 8 includes a buffer pipe 9. The upper part of the buffer pipe 9 is connected to the lower part of the corresponding inlet pipe 1. The lower part of the buffer pipe 9 is also provided with a switch unit 3, which is used to control the lower part of the buffer pipe 9 to open or close.

[0033] In the above embodiment, a buffer unit is set at the lower part of each inlet pipe 1. When the front end conveyor line delivers a delivery bottle into the inlet pipe 1, the switch unit at the lower part of the inlet pipe can be opened first, and the delivery bottle falls into the buffer tube. At this time, an empty conversion unit rotates to the lower part of the buffer tube under the system control. The corresponding switch unit at the lower part of the buffer tube opens, and the delivery bottle falls into the conversion tube. Then, according to the instruction issued by the system, the rotating plate rotates again to drive the conversion tube to the upper part of the designated outlet pipe. Then, the switch unit below the rotating tube opens, and the delivery bottle in the rotating tube enters the outlet pipe and is then delivered to the final position through the rear end conveyor line.

[0034] Please see Figure 4 In the two embodiments described above, the switching unit 3 includes a base plate 301, a cover plate 302, a crank 303, a baffle 304, and a second motor 305. Both the base plate 301 and the cover plate 302 have holes with the same diameter as the pipeline. The base plate 301 and the cover plate 302 form a cavity. The baffle 304 is located in the cavity and can slide within the cavity. By sliding the baffle 304 within the cavity, the holes on the base plate 301 and the cover plate 302 can be closed or opened accordingly. The baffle 304 has a straight groove. The shaft end of the second motor 305 is connected to one end of the crank 303, and the other end of the crank 303 is connected to the straight groove of the baffle 304. The second motor 305 drives the crank 303 to rotate, thereby driving the baffle 304 to reciprocate within the cavity.

[0035] Please see Figure 5 In the above two embodiments, the conversion unit 4 also includes an upper connecting plate 10. The upper connecting plate 10 and the switch unit 3 are fixedly connected by a support rod 11. The top surface of the conversion tube 7 is at the same height as the upper connecting plate 10. The upper connecting plate 10 and the conversion tube 7 are also provided with holes at corresponding positions. A sealing ring 12 is provided at the corresponding hole. By setting the sealing ring, the sealing performance of the entire system can be improved, ensuring the normal delivery of the conveying bottle.

[0036] Please see Figure 1 and Figure 3 In the above two embodiments, a first fixed platform 13 and a second fixed platform 14 are also included. The first fixed platform 13 is fixed above the second fixed platform 14. Multiple inlet pipes 1 are installed on the upper part of the first fixed platform 13, and multiple outlet pipes 2 are installed on the lower part of the second fixed platform 14. A rotating plate 5 is installed on the upper part of the second fixed platform 14, and a first gear (not shown in the figure) is provided on the lower part of the rotating plate 5. A second gear 15 is connected to the output shaft of the first motor 6, and the first gear and the second gear 15 mesh.

[0037] Please continue reading. Figure 3In Embodiment 2, a third fixed platform 15 is also included. The third fixed platform 15 is located between the first fixed platform 13 and the second fixed platform 14, and the cache unit 8 is disposed on the third fixed platform 15.

[0038] There is at least one third fixed platform 15, and each third fixed platform 15 is provided with a buffer unit 8 in the same number and in a position as the inlet pipe 1.

[0039] Please continue reading for details. Figure 3 There are 6 inlet pipes 1, 6 outlet pipes 2 and 6 buffer pipes 9, and they are distributed at equal angles. The outer contours of the first fixed platform 13, the second fixed platform 14 and the third rotating platform 15 are all regular hexagons. The hexagonal positions of the first fixed platform 13 and the hexagonal positions of the third fixed platform 15 are fixedly connected by the support frame 16. The third fixed platform 15 and the second fixed platform 14 are also fixedly connected by the support frame 16.

[0040] Please see Figure 6 Sensors 17 are installed on the sides of the inlet pipe 1, conversion pipe 7, buffer pipe 9, and outlet pipe 2 to detect whether there are conveying bottles in the corresponding pipes. Specifically, multiple sensors 17 are connected to the control system. The sensor on the side of the inlet pipe 1 is used to detect whether there are conveying bottles in the inlet. If there are, the system controls the front-end conveyor line to temporarily not put in new conveying bottles. The sensor on the side of the conversion pipe 7 is used to detect whether there are conveying bottles in the conversion pipe 7. If there are, the system controls the conversion pipe to temporarily not accept other conveying bottles. When the conveying bottles in the conversion pipe are sent out through the corresponding outlet pipe, new conveying bottles will be accepted. The buffer pipe 9 is used to accept the conveying bottles of the corresponding inlet pipe. When the sensor 17 detects that there are no conveying bottles in the buffer pipe 9, the switch unit at the bottom of the inlet pipe corresponding to the buffer pipe opens, and the conveying bottles in the inlet pipe fall into the buffer pipe. When the sensor 17 detects that there are conveying bottles in the buffer pipe 9, the corresponding buffer pipe will temporarily not accept other conveying bottles. The sensor 17 on the side of the outlet pipe 2 is used to detect whether there is a bottle jam at the outlet.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
