Description

Technical Field

[0001] The present application relates to the technical field of pneumatic tube logistics transmission, and in particular to a pneumatic tube logistics transmission bottle buffer. Background Art

[0002] Pneumatic tube logistics transmission system is a modern transportation method, commonly used in hospitals. It uses compressed air as the power, computer control technology, network management and full-process monitoring to connect dozens or even hundreds of workstations such as nurse stations in wards, operating departments, central pharmacies, and laboratories through transmission pipelines. Driven by airflow, it realizes intelligent two-way point-to-point transmission between stations of various small items such as medicines, medical records, specimens, etc. that can be loaded into transmission bottles through dedicated pipelines;

[0003] Since the speed of pneumatic transmission is relatively fast, the transmission bottle has a relatively high speed when it arrives at the station. If it is not buffered, the transmission bottle may have a large collision, which may seriously cause damage to the transmission bottle. Therefore, a buffer is usually set at the receiving position of the work station to buffer the transmission bottle;

[0004] For example, the patent with publication number CN219408348U specifically discloses a bottle blocking device for a pneumatic logistics system. When multiple transmission bottles come in succession in the pipeline and need to be intercepted, the driving device drives the roller to rotate counterclockwise or stop rotating. At this time, the transmission bottle contacts the wheel surface of the roller to generate friction, thereby intercepting the transmission bottle in transit. When the intercepted transmission bottle needs to be put into the pipeline again, the roller rotates in the direction of the downward movement of the transmission bottle, and so on, so that one by one can be put. After the transmission bottle is decelerated by the roller, the speed is greatly reduced. This method can absorb the impact of the transmission bottle and is not easy to damage the transmission bottle.

[0005] In the process of implementing the above patent, because the motor for controlling the rotation of the roller is coaxially arranged with the roller, the blocking collision between the roller and the transmission bottle will act on the motor at the same time. Long-term and frequent collisions will affect the operation of the motor, and seriously reduce the service life of the motor.

[0045] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0046] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0047] Embodiment 1:

[0048] This embodiment describes the basic structure and working principle of the pneumatic tube transport bottle buffer, specifically:

[0049] like Figure 1 As shown, the present application provides a pneumatic tube transport bottle buffer, comprising an upper box body 1 arranged at a work station, and a lower box body 2 fixedly installed at the lower end of the upper box body 1, and a buffer connecting pipe 3 is provided through the interior of the upper box body 1, the buffer connecting pipe 3 protrudes from the upper end of the upper box body 1, and is connected with the transport pipeline of the transport bottle 7, so as to facilitate the transport bottle 7 to be introduced into the buffer connecting pipe 3;

[0050] At the same time, a blocking mechanism 5 is provided inside the upper box body 1 on one side of the buffer connection pipe 3, and the blocking mechanism 5 is used to block and buffer the transmission bottle 7;

[0051] The buffer connection pipe 3 passes through the lower box body 2 downwards, and a bottle outlet pipe 4 is fixedly arranged at the bottom of the lower box body 2, and the bottle outlet pipe 4 is used to export the transmission bottle 7, and a valve body mechanism 6 is arranged between the bottle outlet pipe 4 and the buffer connection pipe 3, and the valve body mechanism 6 is used to open or close the communication between the bottle outlet pipe 4 and the buffer connection pipe 3, so as to facilitate the export of the transmission bottle 7 as needed;

[0052] like Figure 3-Figure 5 As shown, the resistance release mechanism 5 includes a first bracket 51 fixedly mounted on the top of the upper box body 1, a first motor 56 is fixedly mounted on the first bracket 51, a driving shaft 52 is fixedly mounted on the output end of the first motor 56, and the driving shaft 52 is bearing-mounted with the first bracket 51, so that the driving shaft 52 can rotate continuously under the drive of the first motor 56;

[0053] At the same time, a connecting plate 54 is rotatably provided on the first bracket 51, and the upper end of the connecting plate 54 passes through the driving shaft 52, so that the connecting plate 54 can rotate around the axis of the driving shaft 52;

[0054] A driving wheel 53 is fixedly mounted on the driving shaft 52, and a tensioning shaft 58 is mounted at the bottom of the connecting plate 54. A release wheel 57 is fixedly mounted on the tensioning shaft 58. A first belt 55 is connected between the release wheel 57 and the driving wheel 53, so that when the driving shaft 52 rotates, the release wheel 57 can be driven to rotate synchronously through the first belt 55.

[0055] It should be noted that if Fig.11 and Fig.13 As shown, a tensioning waist groove 514 is provided at the bottom of the connecting plate 54, and a tensioning slide plate 515 is slidably provided inside the tensioning waist groove 514, so that the tensioning shaft 58 bearing can be installed on the tensioning slide plate 515, and because the tensioning slide plate 515 is suitable for sliding in the tensioning waist groove 514, the position of the release wheel 57 can be adjusted, and then the tensioning degree of the first belt 55 can be adjusted. In this application, a tensioning screw 59 can be fixedly installed on the connecting plate 54, so that the tensioning slide plate 515 can be sleeved on the tensioning screw 59, and the position of the tensioning slide plate 515 can be adjusted by a nut;

[0056] Continue to refer Figure 5-Figure 6 A spring fixing plate 513 is hinged at the bottom of the connecting plate 54, and a spring fixing nail 510 is fixedly installed at the bottom of the upper box body 1. A first spring 511 is fixedly installed on the spring fixing nail 510, and the other end of the first spring 511 is fixedly installed on the spring fixing plate 513. In this embodiment, a spring adjusting nail 512 is penetrated on the spring fixing plate 513, so that the first spring 511 is fixed on the spring fixing plate 513 through the spring adjusting nail 512;

[0057] In summary, in the initial state, due to the action of the first spring 511, the connecting plate 54 rotates around the first bracket 51 by a certain angle, such as Figure 4 As shown, a notch 31 is provided at the position of the cache connecting tube 3 for the first belt 55, so that when the connecting plate 54 is tilted, the first belt 55 extends into the interior of the cache connecting tube 3;

[0058] When the transmission bottle 7 enters the cache connecting tube 3 under the action of the airflow, it will contact the first belt 55 extending into the cache connecting tube 3 and be blocked by the first belt 55, thereby realizing the blocking function of the transmission bottle 7. At the same time, because the first belt 55 has high elasticity, when the transmission bottle 7 contacts the first belt 55, the transmission bottle 7 can be well buffered and the noise of the transmission bottle 7 during buffering can be reduced to a certain extent.

[0059] In this embodiment, since the transmission bottle 7 is in direct contact with the first belt 55 , the impact force of the transmission bottle 7 does not directly act on the first motor 56 , thereby providing a certain degree of protection for the first motor 56 and extending the life of the first motor 56 .

[0060] When it is necessary to release the transport bottle 7, the first motor 56 is turned on to drive the first belt 55 to be transmitted along the output direction of the transport bottle 7. At this time, the transport bottle 7 is driven to move by the first belt 55 and the first spring 511 is squeezed, so that the first belt 55 rotates and moves away from the buffer connecting tube 3, thereby allowing the transport bottle 7 to pass over the first belt 55 and continue to be transmitted in the buffer connecting tube 3.

[0061] like Figure 1-Figure 2 As shown, the valve body mechanism 6 includes a base 61 fixedly mounted on the bottom of the lower box body 2, and a first through hole (not shown in the figure) matching the bottle outlet pipe 4 is opened on the base 61, and a support plate 67 is fixedly mounted on the upper end of the base 61 inside the lower box body 2, and the support plate 67 is located at the lower end of the buffer connecting pipe 3, and a second through hole (not shown in the figure) matching the buffer connecting pipe 3 is opened, so that the transmission bottle 7 passing through the blocking mechanism 5 can pass through the lower end of the buffer connecting pipe 3, and sequentially enter the interior of the bottle outlet pipe 4 through the second through hole and the first through hole, so as to facilitate the collection of the transmission bottle 7;

[0062] At the same time, an insert plate 65 is slidably arranged between the base 61 and the support plate 67, and the insert plate 65 is used to open or close the connection channel between the first through hole and the second through hole;

[0063] In order to control the sliding of the plug board 65, a second bracket 62 is fixedly mounted on the base 61, a second motor 63 is fixedly mounted on the second bracket 62, and a first gear 66 is fixedly mounted on the output end of the second motor 63. The first gear 66 is bearing-mounted with the second bracket 62, so that the first gear 66 can be driven to rotate under the action of the second motor 63. In this embodiment, the second motor 63 is a bidirectional motor, so that the first gear 66 can be driven to rotate in the forward or reverse direction;

[0064] At the same time, a first rack 64 is fixedly mounted on the plug plate 65, and the first rack 64 is meshed with the first gear 66, so that the connection channel between the first through hole and the second through hole can be opened or closed by rotating the first gear 66, so as to release or block the transmission bottle 7 as needed.

[0065] like Figure 7As shown, a groove (not shown in the figure) is provided at a position of the inserting plate 65 between the first through hole and the second through hole, an elastic member 68 is fixedly installed at the bottom of the groove, and a bottle receiving plate 69 is fixedly installed at the other end of the elastic member 68. The bottle receiving plate 69 is adapted to abut against the bottom of the second through hole under the action of the elastic member 68, thereby forming a sealed space in the second through hole;

[0066] Therefore, when the transport bottle 7 falls onto the bottle receiving plate 69, the floating seal of the bottle receiving plate 69 forms an effective air cushion in the buffer connecting pipe 3 and the sealed space, thereby slowing down the falling speed of the transport bottle 7 and effectively reducing the impact of the transport bottle 7 when it falls.

[0067] Embodiment 2:

[0068] In the working process of the first embodiment, the switching process between the blocking and releasing mechanism 5 needs to be completed by starting and stopping the first motor 56, and frequent starting and stopping will undoubtedly affect the life of the first motor 56, especially in the fast-paced transmission of the transmission bottle 7, the first motor 56 needs to be switched continuously, which will cause a great burden on the first motor 56;

[0069] In order to solve the above problems, Figure 8 As shown, for the convenience of description, the sealing plate on the top of the upper box body 1 is defined as a top plate 11, the sealing plates on the sides of the upper box body 1 are defined as a first side plate 12 and a second side plate 13, and the sealing plate on the bottom of the upper box body 1 is defined as a bottom plate 14;

[0070] Meanwhile, a pressing mechanism 8 is provided on the first side plate 12, and the pressing mechanism 8 is used to intermittently press the first belt 55, so that the first belt 55 can be pressed and extended into the buffer connection pipe 3 to press and block the transmission bottle 7, and the first belt 55 can be in a free state and away from the buffer connection pipe 3, so that the transmission bottle 7 can pass smoothly;

[0071] like Figure 8-Figure 10 As shown, the pressing mechanism 8 includes a gear shaft 81 disposed on the first side plate 12, and a second gear 82 is fixedly mounted on the gear shaft 81. Meanwhile, a driving part 9 is disposed on the first side plate 12, so that the second gear 82 can continuously rotate under the drive of the driving part 9. In this embodiment, the driving part 9 can be a hydraulic motor;

[0072] Meanwhile, a fixing ring 83 is fixedly mounted on the first side plate 12, a locking shaft 84 is slidably penetrated on the fixing ring 83, a tooth plate 86 is fixedly mounted on the locking shaft 84 at a position away from the fixing ring 83, and a second spring 85 is installed between the tooth plate 86 and the fixing ring 83, so that the locking shaft 84 can slide on the fixing ring 83 to drive the tooth plate 86 to move horizontally synchronously. In this embodiment, a boss (not shown in the figure) is arranged on the locking shaft 84 to prevent the locking shaft 84 from falling off the fixing ring 83 when sliding;

[0073] A second rack 87 is provided at the lower end of the toothed plate 86, and the second rack 87 is meshed with the second gear 82, so that when the second gear 82 rotates, the toothed plate 86 can be driven to slide horizontally through the meshed second rack 87, and the second spring 85 can be stretched or compressed;

[0074] Continue to refer Figure 8-Figure 10 A slide groove 861 is provided on the tooth plate 86, and an independent tooth 813 is slidably provided in the slide groove 861, and a fourth spring 814 is fixedly installed between the independent tooth 813 and the tooth plate 86, so that in the initial state, due to the action of the fourth spring 814, the independent tooth 813 and one end of the second rack 87 have a certain distance, and the distance is the tooth pitch length of the second rack 87;

[0075] Meanwhile, a fixing block 88 is fixedly mounted on the tooth plate 86, a holding shaft 89 is fixedly mounted on the fixing block 88, a holding wheel 816 is fixedly mounted on the holding shaft 89, and the holding wheel 816 is located in the middle of the first belt 55, and in the initial state, the holding wheel 816 does not contact the first belt 55;

[0076] A first waist groove 810 is provided horizontally on the first side plate 12, and the first waist groove 810 is used to avoid the holding shaft 89 when it moves horizontally.

[0077] In summary, what is different from the first embodiment is that in the initial state, the first belt 55 is in a vertical state under the action of the first spring 511, that is, the first belt 55 does not have a blocking effect on the transmission bottle 7 in the initial state;

[0078] When the transmission bottle 7 needs to be blocked, the driving part 9 is started to drive the second gear 82 to rotate, so that as the second gear 82 rotates, the tooth plate 86 is driven to move horizontally, and then the holding shaft 89 and the holding wheel 816 are driven to approach the buffer connection pipe 3 through the fixing block 88;

[0079] When the second gear 82 reaches the end of the second rack 87, the pressing wheel 816 contacts the first belt 55 near the cache connection pipe 3 and starts to press the first belt 55 toward the cache connection pipe 3.

[0080] When the second gear 82 passes over the end of the second rack 87, it will mesh with the independent tooth 813. After the second rack 87 meshes with the independent tooth 813, it will drive the independent tooth 813 to approach the second rack 87, and under the action of the fourth spring 814, it will drive the tooth plate 86 to continue to approach the cache connecting pipe 3, and drive the holding wheel 816 to press the first belt 55 into the cache connecting pipe 3, and block the transmission bottle 7;

[0081] As the second gear 82 continues to rotate, when the second gear 82 is disengaged from the independent tooth 813, the independent tooth 813 will be reset under the action of the fourth spring 814, and drive the tooth plate 86 to reset a short distance, so that the first belt 55 leaves the buffer connection tube 3, thereby releasing the obstruction to the transmission bottle 7;

[0082] Thus, through the continuous rotation of the second gear 82, intermittent meshing with the independent tooth 813 can be achieved, so as to drive the holding wheel 816 to intermittently hold the first belt 55, thereby realizing the alternating operation of blocking and releasing the transport bottle 7, and thus being able to adapt to the operation of buffering a large number of transport bottles 7;

[0083] In this embodiment, the first motor 56 can continuously transmit, and can also achieve buffering and blocking of the transmission bottle 7 , without the need for frequent starting and stopping of the first motor 56 , thereby extending the life of the first motor 56 .

[0084] In this embodiment, the frequency of the spacing of the bottles can be adjusted by setting the pitch of the second gear 82 to adapt to the transmission of the transmission bottle 7 at different speeds.

[0085] In order to achieve the reset of the first belt 55, as Figure 11-Figure 12 As shown, a cylinder 96 is fixedly installed inside the first side plate 12, and a connecting seat 97 is fixedly installed at the output end of the cylinder 96. At the same time, the connecting seat 97 is fixedly installed with the gear shaft 81 at a position away from the cylinder 96, so that when the first belt 55 needs to be reset, the output end of the cylinder 96 is contracted to move the second gear 82 downward, thereby causing the second gear 82 to be out of mesh with the second rack 87;

[0086] When the second gear 82 is disengaged from the second rack 87, the tooth plate 86 is reset under the action of the second spring 85, thereby driving the holding wheel 816 to reset, and then the first belt 55 is reset. It should be noted that a third waist groove 98 matching the gear shaft 81 is opened on the first side plate 12 to facilitate the gear shaft 81 to move vertically following the cylinder 96.

[0087] In this embodiment, the driving unit 9 for driving the second gear 82 can be synchronously controlled by the first motor 56, specifically:

[0088] like Fig.11 As shown, a long shaft (not shown) is fixed on the output end of the first motor 56, a first belt pulley 91 is fixedly mounted on the long shaft, and a fourth belt pulley 94 is fixedly mounted on the gear shaft 81, and a second belt 95 is connected between the fourth belt pulley 94 and the first belt pulley 91, so that when the first motor 56 is working, the second gear 82 can be driven to rotate synchronously, avoiding the use of additional power components;

[0089] At the same time, in order to match the movement of the second gear 82, two sets of second waist grooves 811 are opened on the first side plate 12, and a third spring 812 is fixedly installed inside the second waist groove 811. At the same time, a wheel shaft 99 is fixedly installed on the third spring 812, and a second pulley 92 (third pulley 93) is installed on the bearing of the wheel shaft 99. The second pulley 92 and the third pulley 93 are both connected to the second belt 95 in transmission, so that the second pulley 92 (third pulley 93) can realize the tensioning function under the action of the third spring 812 to adapt to the adjustment of the second gear 82.

[0090] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
