Description

Technical Field

[0001] The present invention relates to the field of medical devices, and more particularly to a pneumatic logistics long-distance multi-bottle conveying system. Background Art

[0002] Pneumatic logistics is currently widely used in large hospitals. Pneumatic logistics mainly includes a receiving station, a sending station, a conveying pipe, a transmission bottle, and a wind source. The receiving station and the sending station are arranged in each department or a centralized site of the hospital. The receiving station and the sending station are connected by a conveying pipe. The wind source can provide air flow into the conveying pipe. Medical staff can place the transmission bottle into the conveying pipe through the sending station. The transmission bottle can contain medicine or bills inside. The transmission bottle in the conveying pipe moves forward by the push of the wind force, so that it is transferred from the sending station to the receiving station; this logistics system has a simple structure, a fast transmission speed, and a high conveying efficiency; however, it still has deficiencies, mainly reflected in the long-distance conveying of the transmission bottle. The conveying pipe generally has two paths, namely a forward conveying pipeline and a reverse conveying pipeline. Whether it is forward or reverse, for an extremely long conveying pipe, the existing pneumatic logistics system only allows a single transmission bottle to be transmitted in the conveying pipe at a time, that is, after one transmission bottle is moved from the sending station to the receiving station, another transmission bottle can be placed. Then, for long-distance conveying, the above single-placement method is obviously too inefficient to meet the requirements of the daily material exchange speed in the hospital.

[0003] Therefore, how to provide a pneumatic logistics long-distance multi-bottle conveying system to overcome the above problems is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the present invention provides a pneumatic logistics long-distance multi-bottle conveying system.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A pneumatic logistics long-distance multi-bottle conveying system, comprising: a conveying pipe, a sending station, a receiving station, an air source and a transmission bottle. The two ends of the conveying pipe are respectively provided with a sending station and a receiving station. The air source is pneumatically connected to the conveying pipe. The transmission bottle can be slidably arranged in the conveying pipe. The system further includes a stopping mechanism. A plurality of stopping mechanisms are installed on the conveying pipe, and the plurality of stopping mechanisms are arranged in sequence along the pipe length direction of the conveying pipe. The stopping mechanism includes a main pipe, a branch pipe, a blocking member and a non-contact sensor. The main pipe is connected in series on the conveying pipe, and the transmission bottle can be arranged in the main pipe. The side wall of the main pipe is provided with ventilation holes. One end of the branch pipe is communicated with the ventilation holes. The blocking member includes a limiting shell, a sliding core and a telescopic member. The limiting shell has an inlet and an outlet opposite to the position of the inlet. The limiting shell is connected in series on the main pipe. An air inlet is opened on the limiting shell. One end of the branch pipe away from the ventilation holes is communicated with the air inlet. The transmission bottle can be arranged between the ventilation holes and the limiting shell. The sliding core is slidably and tightly arranged in the limiting shell. The side wall of the sliding core can block the inlet, and the side wall of the sliding core can block the air inlet. The telescopic member is installed on the limiting shell, and the telescopic end of the telescopic member is connected to the sliding core. The telescopic direction of the telescopic end of the telescopic member is the same as the length direction of the sliding core. A through hole and a wind guiding channel are opened on the sliding core. The through hole penetrates through the two opposite side walls of the sliding core. The through hole can be opposite to and communicated with the inlet and the outlet at the same time. The transmission bottle can be arranged in the through hole. One end of the wind guiding channel is communicated with the through hole, and the other end of the wind guiding channel penetrates through one side wall of the sliding core. The end of the wind guiding channel away from the through hole can be opposite to and communicated with the outlet. The through hole can be opposite to and communicated with the air inlet. A single stopping mechanism has two non-contact sensors that can be triggered by the transmission bottle. Both non-contact sensors are installed on the main pipe, and both the limiting shell and the ventilation holes are limited between the two non-contact sensors.

[0007] As can be seen from the above technical solutions, compared with the prior art, the present invention discloses and provides a pneumatic logistics long-distance multi-bottle conveying system. In this application, a plurality of stopping mechanisms are arranged on the conveying pipe, and the plurality of stopping mechanisms are arranged in sequence along the pipe length direction of the conveying pipe. Multiple transfer bottles can move in the conveying pipe simultaneously, that is, it is not necessary for one transfer bottle to complete delivery and reception before delivering another transfer bottle. In the stopping mechanism, the telescopic member can drive the sliding core to move. The sliding core has two working positions, namely the blocking position and the releasing position. For the blocking position, the outer sidewall of the sliding core blocks the inlet, one end of the through hole is blocked by the plate surface of the cover plate, the other end of the through hole is communicated with the air inlet, and the outlet is communicated with the air guiding channel. The sliding core can block the transfer bottle without affecting the air flow in the conveying pipe. For the releasing position, the outer sidewall of the sliding core blocks the air inlet, one end of the air guiding channel away from the through hole is blocked by the plate surface of the cover plate, and both ends of the through hole are respectively aligned with and communicated with the inlet and the outlet. The stopping mechanism can quickly and reliably block the transfer bottle behind, while the transfer bottle in front can still be pushed by the wind force. By designing a non-contact sensor, when a transfer bottle passes through two non-contact sensors in a stopping mechanism in sequence, it can be determined that the transfer bottle has completed the transfer from one conveying section to another. At the same time, the positions of the front and rear transfer bottles can be judged through the non-contact sensor, thereby avoiding collision or blockage of adjacent transfer bottles.

[0008] Preferably, the inner diameter of the conveying pipe, the diameter of the inlet, the diameter of the outlet, and the inner diameter of the through hole are all the same as the inner diameter of the main pipe, and the inner sidewall of the conveying pipe is aligned with the inner sidewall of the main pipe. The transfer bottle can smoothly pass through the stopping mechanism.

[0009] Preferably, the limiting shell includes a shell body and a cover plate. One sidewall of the shell body is open and is detachably sealed with a cover plate. An inlet and an air inlet are provided on the other sidewall of the shell body opposite to its open sidewall, and an outlet is provided on the cover plate. The outer sidewall of the sliding core can be in sliding and close contact with the inner wall of the shell body and one side plate surface of the cover plate. The telescopic member is installed on the shell body. The sliding core can be reliably installed in the shell body.

[0010] Preferably, one end of the shell body is provided with an opening and is slidably and tightly inserted with a connecting rod. One end of the connecting rod is fixed to one end of the sliding core, and the length direction of the connecting rod is the same as the length direction of the sliding core.

The telescopic cylinder is fixed on the shell body, the telescopic direction of the telescopic rod of the telescopic cylinder is the same as the length direction of the sliding core, one end of the connecting member is fixed to the telescopic rod of the telescopic cylinder, and the other end of the connecting member is fixed to the end of the connecting rod away from the sliding core. The telescopic cylinder can reliably drive the sliding core to move.

The non-contact sensor is fixed on the main pipe, a light-transmitting hole is provided on the sidewall of the main pipe, and the detection end of the non-contact sensor is located inside the light-transmitting hole.

Detailed implementation mode

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] The present invention discloses a pneumatic logistics long-distance multi-bottle conveying system. In this application, a plurality of stopping mechanisms are arranged on the conveying pipe 1, and the plurality of stopping mechanisms are arranged in sequence along the pipe length direction of the conveying pipe 1. A plurality of transmission bottles 5 can move simultaneously in the conveying pipe 1, that is, it is not necessary for one transmission bottle 5 to complete delivery and reception before delivering another transmission bottle 5;

[0026] In the stopping mechanism, the telescopic member can drive the sliding core 10 to move. The sliding core 10 has two working positions, namely the blocking position and the releasing position; for the blocking position, the outer side wall of the sliding core 10 blocks the entrance, one end of the through hole 11 is blocked by the plate surface of the cover plate 9, the other end of the through hole 11 is communicated with the air inlet, and the outlet is communicated with the air guiding channel 12. The sliding core 10 can block the transmission bottle 5 without affecting the air flow in the conveying pipe 1; for the releasing position, the outer side wall of the sliding core 10 blocks the air inlet, one end of the air guiding channel 12 away from the through hole 11 is blocked by the plate surface of the cover plate 9, and both ends of the through hole 11 are respectively aligned with and communicated with the entrance and the outlet;

[0027] The stopping mechanism can quickly and reliably block the rear transmission bottle 5, while the front transmission bottle 5 can still be pushed by the wind force;

[0028] By designing the non-contact sensor 15, when a transmission bottle 5 passes through two non-contact sensors 15 in a stopping mechanism in sequence, it can be judged that the transmission bottle 5 has completed the transfer from one conveying section to another; at the same time, the positions of the front and rear transmission bottles 5 can be judged through the non-contact sensor 15, thereby avoiding collision or blockage of adjacent transmission bottles 5;

[0029] In this application, holes can also be opened on the outer side wall of the sliding core 10 and elastic buffer pads (not shown in the figure) can be installed. The elastic buffer pads can be aligned with the entrance position. When the sliding core 10 is in the blocking position, the transmission bottle 5 will not be directly in hard contact with the sliding core 10;

[0030] The outer wall of the sliding core 10 blocks the entrance in a continuous process, that is, the sliding core 10 will not block the entrance instantly; in the process of the through hole 11 and the entrance gradually staggered, the transmission bottle 5 that is about to be blocked by the sliding core 10 can still move forward, and when the sliding core 10 completely blocks the entrance, there is still a certain space A between the transmission bottle 5 that is about to be blocked by the sliding core 10 and the sliding core 10. At the same time, the transmission bottle 5 that is about to be blocked by the sliding core 10 will not block the ventilation hole, and the wind flow in the conveying pipe 1 behind the sliding core 10 can enter the ventilation hole. Due to the existence of the above-mentioned space A, when the transmission bottle 5 continues to move forward due to wind force or its own inertia, the above-mentioned space A is compressed, and the gas in the space A can play a buffering role for the transmission bottle 5;

[0031] By designing the speed sensor 17, the speed of the transmission bottle 5 in the conveying pipe 1 can be monitored, so as to facilitate the adjustment of the air volume delivered by the air source 4 to the conveying pipe 1;

[0032] The telescopic cylinder 13 can reliably drive the sliding core 10 to move in the limiting housing.

[0033] Example

[0034] See attached Figures 1-6 The overall and partial structural schematic diagram of an embodiment of the present invention specifically discloses a pneumatic logistics long-distance multi-bottle conveying system, including: a conveying pipe 1, a sending station 2, a receiving station 3, an air source 4 and a transmission bottle 5;

[0035] A sending station 2 and a receiving station 3 are respectively provided at both ends of the conveying pipe 1. The user can fill the transmission bottle 5 to be sent through the sending station 2. The transmission bottle 5 enters the conveying pipe 1 through the sending station 2. The transmission bottle 5 can move flexibly in the conveying pipe 1. The wind source 4 is connected to the air path of the conveying pipe 1. There is wind pressure in the conveying pipe 1 behind the transmission bottle 5. The wind force pushes the transmission bottle 5 in the conveying pipe 1 to move toward the receiving station 3. The receiving station 3 can receive the transmission bottle 5 from the sending station 2. The sending station 2, the receiving station 3 and the wind source 4 are all existing technologies.

[0036] In addition to the above structure, the system also includes a stop mechanism. The delivery pipe 1 is equipped with a plurality of stop mechanisms, which are arranged equidistantly in sequence along the length direction of the delivery pipe 1.

[0037] The stop mechanism includes a main pipe 6, a branch pipe 7, a blocking member and a non-contact sensor 15. The main pipe 6 is connected in series to the delivery pipe 1. The center line of the main pipe 6 coincides with the center line of the delivery pipe 1. The transmission bottle 5 in the delivery pipe 1 can pass through the inside of the main pipe 6. The side wall of the main pipe 6 is provided with a ventilation hole.

[0038] The blocking member includes a limiting shell, a sliding core 10 and a telescopic member. The limiting shell has an inlet and an outlet opposite to the inlet. The limiting shell is connected in series on the main pipe 6. The transfer bottle 5 can pass through the inlet and the outlet in sequence. An air inlet is provided on the limiting shell. One end of the branch pipe 7 is communicated with the ventilation hole, and the other end of the branch pipe 7 is communicated with the air inlet. The transfer bottle 5 can be arranged between the ventilation hole and the limiting shell;

[0039] The sliding core 10 is slidably and tightly arranged in the limiting shell. The sliding core 10 can move in the limiting shell. The moving direction of the sliding core 10 is the same as its own length direction. The moving direction of the sliding core 10 is perpendicular to the pipe length direction of the main pipe 6. The side wall of the sliding core 10 can block the inlet, and the side wall of the sliding core 10 can block the air inlet;

[0040] The sliding core 10 is provided with a pneumatic balance channel 19. The pneumatic balance channel 19 runs through the two end walls of the sliding core 10. Since the side wall of the sliding core 10 is in sliding and tight contact with the inner side wall of the limiting shell, the design of the pneumatic balance channel 19 can ensure that the sliding core 10 can move flexibly in the sealed limiting shell;

[0041] The telescopic member is installed on the limiting shell. The telescopic end of the telescopic member is connected to the sliding core 10. The telescopic direction of the telescopic end of the telescopic member is the same as the length direction of the sliding core 10. The telescopic member can drive the sliding core 10 to reciprocate in the limiting shell;

[0042] The sliding core 10 is provided with a through hole 11 and a wind guiding channel 12. The through hole 11 runs through the two opposite side walls of the sliding core 10. The through hole 11 can be directly opposite to and communicated with the inlet and the outlet at the same time. The transfer bottle 5 can pass through the through hole 11; One end of the wind guiding channel 12 is communicated with the through hole 11, and the other end of the wind guiding channel 12 runs through one side wall of the sliding core 10; When the sliding core 10 moves to a certain position, the end of the wind guiding channel 12 away from the through hole 11 is directly opposite to and communicated with the outlet, and at this time the through hole 11 is directly opposite to and communicated with the air inlet;

[0043] A single stopping mechanism has two non-contact sensors 15 that can be triggered by the transfer bottle 5. Both non-contact sensors 15 are installed on the main pipe 6. The limiting shell and the ventilation hole are both limited between the two non-contact sensors 15.

[0044] The inner diameter of the conveying pipe 1, the diameter of the inlet, the diameter of the outlet, and the inner diameter of the through hole 11 are the same as the inner diameter of the main pipe 6. The inner side wall of the conveying pipe 1 is aligned with the inner side wall of the main pipe 6. This design ensures that the transfer bottle 5 in the conveying pipe 1 can smoothly pass through the main pipe 6 and the limiting shell.

[0045] The limiting shell includes a shell 8 and a cover plate 9. One side wall of the shell 8 is open and is detachably sealed with the cover plate 9. Another side wall of the shell 8 opposite to its open side wall is provided with an inlet and an air inlet. The cover plate 9 is provided with an outlet. The outer side wall of the sliding core 10 can be in sliding and close contact with the inner wall of the shell 8 and one side plate surface of the cover plate 9. The material of the sliding core 10 is polytetrafluoroethylene, which has good wear resistance. The telescopic member is installed on the shell 8; the operator can open the cover plate 9 to maintain the sliding core 10.

[0046] One end of the shell 8 is provided with an opening and is slidably and tightly inserted with a connecting rod 16. One end of the connecting rod 16 is fixed to one end of the sliding core 10. The length direction of the connecting rod 16 is the same as the length direction of the sliding core 10; the telescopic member includes a telescopic cylinder 13 and a connecting member 14. The telescopic cylinder 13 is fixed on the shell 8. The telescopic cylinder 13 in this application is an electric cylinder. The telescopic direction of the telescopic rod of the telescopic cylinder 13 is the same as the length direction of the sliding core 10. One end of the connecting member 14 is fixed to the telescopic rod of the telescopic cylinder 13, and the other end of the connecting member 14 is fixed to the end of the connecting rod 16 away from the sliding core 10. The telescopic cylinder 13 can drive the connecting member 14 to move reciprocally, so as to realize the reciprocating movement of the connecting rod 16 and the sliding core 10 connected thereto.

[0047] Further specifically, the non-contact sensor 15 in this application is a photoelectric sensor. The non-contact sensor 15 is fixed on the main pipe 6. A light-transmitting hole is provided on the side wall of the main pipe 6. The detection end of the non-contact sensor 15 is located inside the light-transmitting hole. The detection end of the non-contact sensor 15 can be aligned with the pipe center line of the main pipe 6. When the transmission bottle 5 passes through the light-transmitting hole, the transmission bottle 5 can trigger the non-contact sensor 15.

[0048] Further specifically, it further includes a speed sensor 17. The speed sensor 17 is fixed on the conveying pipe 1. The detection end of the speed sensor 17 is aligned with the pipe center line of the conveying pipe 1. The speed sensor 17 can monitor the speed of the transmission bottle 5 passing through it, which helps to judge the action timing of the telescopic cylinder 13 and is convenient for adjusting the air volume conveyed by the air source 4 into the conveying pipe 1.

[0049] Further specifically, it further includes a controller 18. The controller 18 can be installed on the sending station 2. The non-contact sensor 15, the telescopic cylinder 13 and the speed sensor 17 are all electrically connected to the controller 18. The controller 18 can receive the electrical signals from the non-contact sensor 15 and the speed sensor 17, so as to control the telescopic cylinder 13.

[0050] The operating principle of this conveying system:

[0051] The sliding core 10 in the blocking member has two working positions, namely the blocking position and the releasing position, as Figure 5 and Figure 6 shown. The direction of the arrow in the figure is the direction of the air flow;

[0052] For the blocking station, that is, when the sliding core 10 is in a certain position in the limiting shell, the outer side wall of the sliding core 10 blocks the entrance, one end of the through hole 11 is blocked by the plate surface of the cover plate 9, the other end of the through hole 11 is communicated with the air inlet, and the outlet is communicated with the air guiding channel 12. The sliding core 10 can block the transmission bottle 5, but does not affect the air flow in the conveying pipe 1;

[0053] For the release station, that is, when the sliding core 10 is in a certain position in the limiting shell, the outer side wall of the sliding core 10 blocks the air inlet, one end of the air guiding channel 12 away from the through hole 11 is blocked by the plate surface of the cover plate 9, and both ends of the through hole 11 are respectively opposite to and communicated with the entrance and the outlet;

[0054] A plurality of stopping mechanisms are connected in series at equal intervals on the conveying pipe 1. The sections between adjacent stopping mechanisms are conveying sections. From the sending station 2 to the receiving station 3, it can be divided into the first conveying section, the second conveying section... the nth conveying section;

[0055] The operator puts a transmission bottle 5 into the conveying pipe 1 through the sending station 2, and the transmission bottle 5 moves towards the receiving station 3 under the blowing of the wind;

[0056] In the initial state, the sliding cores 10 in a plurality of stopping mechanisms are all in the release station;

[0057] When the first transmission bottle 5 passes by the non-contact sensor 15 at the rear end in the first stopping mechanism, the non-contact sensor 15 is triggered, and the controller 18 reminds the operator at the sending station 2 by means of a prompt sound, a prompt light or a screen text display, reminding him that he can put the second transmission bottle 5;

[0058] The second transmission bottle 5 enters the conveying pipe 1. As the second transmission bottle 5 moves forward, when the second transmission bottle 5 triggers the non-contact sensor 15 at the front end in the first stopping mechanism, there are two situations:

[0059] One is that if the first transmission bottle 5 is in the second conveying section, the controller 18 controls the telescopic cylinder 13 in the first stopping mechanism to act quickly, so that the sliding core 10 in the first stopping mechanism moves to the blocking station, and the second transmission bottle 5 is blocked by the sliding core 10 in the first stopping mechanism, and the second transmission bottle 5 stops moving forward; when the first transmission bottle 5 moves to the third conveying section, the controller 18 controls the telescopic cylinder 13 in the first stopping mechanism to act quickly, so that the sliding core 10 in the first stopping mechanism moves to the release station, and the second transmission bottle 5 continues to move forward;

[0060] The other is that if the first transmission bottle 5 is in the third conveying section, the fourth conveying section... or the nth conveying section, the sliding core 10 in the first stopping mechanism maintains the release station, and the second transmission bottle 5 can continue to move forward and pass through the first stopping mechanism;

[0061] When the (n - 1)-th transport bottle 5 passes by the non-contact sensor 15 at the rear end in the first stop mechanism, the non-contact sensor 15 is triggered, and the controller 18 reminds the operator at the sending station 2 by means of a prompt tone, a prompt light, or screen text display, reminding the operator that the n-th transport bottle 5 can be placed; through the above operations, multiple transport bottles 5 can be transported in a single conveying pipe 1;

[0062] In short, no matter how many transport bottles 5 are placed into the conveying pipe 1, there should be at least one conveying section between every two adjacent transport bottles 5 along the length direction of the conveying pipe 1, so as to ensure that there will be no collision or accumulation between multiple transport bottles 5 in the conveying pipe 1;

[0063] When a transport bottle 5 passes by two non-contact sensors 15 in a stop mechanism in sequence, then the transport bottle 5 completes the transfer from one conveying section to another.

[0064] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. For the same or similar parts among the embodiments, reference can be made to each other.

[0065] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather will be accorded the widest scope consistent with the principles and novel features disclosed herein.
