Description

Technical Field

[0001] This utility model relates to the field of conveying, specifically to an automatic bottle feeding device and workstation for pneumatic logistics. 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] The hospital pneumatic logistics system uses compressed air to drive a special delivery bottle in the pipeline to transport materials. It is characterized by high speed and quick response. However, since it uses compressed air, only one delivery bottle can be used in the pipeline at a time, and each delivery must wait for the previous delivery task to be completed before it can start.

[0004] The current hospital pneumatic tube system uses a manual bottle placement design at its workstations. The operation logic is: place the bottle at the station – wait in line for the task to begin – the bottle enters the pipeline – transport begins – wait for completion. Therefore, each bottle placement requires waiting for all preceding tasks to finish before placing the next bottle. When multiple bottles need to be transported, operators must queue them sequentially. This results in operators waiting at each station for the previous bottle to finish before placing another, leading to extremely low work efficiency. Therefore, there is an urgent need for a device to add a mechanism to the existing hospital pneumatic tube system that provides a buffer for bottles awaiting dispatch, reducing operators' unnecessary waiting time and improving staff efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an automatic pneumatic logistics bottle feeding device and workstation.

[0006] The specific technical solution is as follows: an automatic bottle feeding device for pneumatic logistics includes a base plate, guide frames, a motor, and a drive plate. There are two guide frames fixed to the upper part of the base plate. The two guide frames and the base plate form a channel for placing a single row of conveying bottles. The motor is fixed to one side of the base plate. The drive plate is connected to the output shaft of the motor. The motor drives the drive plate to rotate. The drive plate is provided with an arc-shaped groove that can accommodate the conveying bottles. With the rotation of the drive plate, the conveying bottles in the channel enter the arc-shaped groove in sequence and move linearly in the channel with the rotation of the drive plate.

[0007] Furthermore, the drive plate is cross-shaped, and the drive plate is provided with four arc-shaped grooves.

[0008] Furthermore, there are two drive plates, and the two drive plates are connected by a timing belt to rotate synchronously. The channel formed by the guide frame and the base plate is long enough to hold four conveying bottles. The two drive plates are located at the middle positions of the first and second conveying bottles and the middle positions of the third and fourth conveying bottles, respectively.

[0009] Furthermore, a support frame is provided on the base plate, and the two drive plates are connected to the support frame.

[0010] Furthermore, the guide frame is higher than 1 / 2 of the height of the conveying bottle, and the guide frame is also provided with a horizontal support plate to prevent the conveying bottle from falling off the side.

[0011] A pneumatic logistics workstation includes a station and a main delivery pipe. A movable delivery pipe is provided inside the station. An opening for inserting delivery bottles is provided at the top of the station. The movable delivery pipe reciprocates between the opening and the main delivery pipe. An automatic bottle feeding device is included.

[0012] Furthermore, a first baffle is fixed to the side of the mobile conveying pipe, and a second baffle is provided on the side of the main conveying pipe. When the mobile conveying pipe moves and aligns with the hole on the station, the second baffle blocks the bottom of the mobile conveying pipe. When the mobile conveying pipe aligns with the main conveying pipe, the first baffle blocks the hole at the top of the station.

[0013] Furthermore, an arc-shaped guide is fixed to the side of the hole on the site.

[0014] Compared with the prior art, the technical solution proposed in this utility model sets up an automatic bottle feeding device at the station. When the operator arrives at the station, if there is no conveying task at that time, the operator can directly operate the station to align the moving conveyor pipe with the bottle feeding hole on the station and put the conveyed bottle into the conveyor line. If the previous task has not been completed, the conveyed bottle can be placed at the bottle feeding hole position of the station. In the case of multiple bottles, they can be arranged sequentially on the channel of the bottle feeding device. In this way, when the previous conveyed bottle in the main conveying pipe is completed, the moving conveyor pipe moves to below the hole position, and the conveyed bottle in the hole falls into the moving conveyor pipe. Then the moving conveyor pipe is aligned with the main conveying pipe, and at the same time the motor drives the drive plate to rotate, pushing the conveyed bottles on the channel forward. The first conveyed bottle will stop at the hole position, waiting for the previous conveying work to be completed, and then the above process is repeated. During the process, the operator does not need to wait at the station, and the work efficiency is higher. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are only some embodiments of the utility model, 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.

[0023] To address the problems existing in the relevant prior art, this utility model proposes an automatic bottle feeding device and workstation for pneumatic logistics. The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1 to 4This utility model proposes an automatic bottle feeding device for pneumatic logistics, including a base plate 1, a guide frame 2, a motor 3, and a drive plate 4. Specifically, the base plate 1 is set on one side of the station 5, and the height of the base plate 1 is the same as the height of the top surface of the station 5. There are two guide frames 2, which are fixed to the upper part of the base plate 1. In this way, the two guide frames 2 and the base plate 1 form a channel for placing a single row of conveyor bottles 6, and one end of the channel is aligned with the hole for placing conveyor bottles in the station 5. The motor 3 is fixed to one side of the base plate 1, and the drive plate 4 is connected to the output shaft of the motor 3. The motor 3 drives the drive plate 4 to rotate. The drive plate 4 is provided with an arc-shaped groove that can accommodate the conveyor bottles 6. With the rotation of the drive plate 4, the conveyor bottles 6 in the channel enter the arc-shaped groove in sequence and move linearly in the channel with the rotation of the drive plate 4, and finally push the conveyor bottles 6 into the hole for placing conveyor bottles in the station 5.

[0025] Please see Figure 3 Specifically, in the above scheme, the drive plate 4 is cross-shaped, thus forming four arc-shaped grooves on the drive plate 4, and the ends of the drive plate are rounded to prevent the drive plate 4 from getting stuck in the arc-shaped grooves.

[0026] Please continue reading. Figure 3 There are two drive plates 4, and the two drive plates 4 are connected by a synchronous belt 7 to rotate synchronously. Specifically, there is a synchronous wheel at the bottom of each of the two drive plates, and the synchronous belt 7 connects the synchronous wheels of the two drive plates, so that the two drive plates can rotate synchronously. The channel formed by the guide frame 2 and the base plate 1 can hold four conveying bottles 6. The two drive plates are located in the middle of the first and second conveying bottles and in the middle of the third and fourth conveying bottles, respectively. With the above settings, the conveying bottles in the arc groove of the first drive plate can move towards the direction of the second drive plate under the rotation of the drive plate, and be driven by the second drive plate to continue moving forward.

[0027] It is understandable that there can also be three drive plates, and the channel length can accommodate six conveying bottles. In this case, the drive plates are located in the middle of the first and second conveying bottles, the middle of the third and fourth conveying bottles, and the middle of the fifth and sixth conveying bottles, and so on. Its working principle is the same as that of the two drive plates mentioned above. At the same time, a support frame 8 is provided on the base plate 1, and the two drive plates 4 are connected to the support frame 8. In order to prevent interference during rotation, the drive plates 4 can be set at staggered heights, or they can be set at the same height if no interference occurs.

[0028] The guide frame 2 is higher than 1 / 2 the height of the conveying bottle, and the guide frame is also equipped with a horizontal support plate to prevent the conveying bottle from falling from the side. With the above settings, the conveying bottle can be effectively prevented from falling from both sides of the guide frame 2 during the movement due to the high center of gravity.

[0029] Please see Figures 4 to 6Based on the same working principle, this utility model also proposes a pneumatic logistics workstation, including a station 5 and a main conveying pipe 9. A movable conveying pipe 10 is provided inside the station 5, and a hole for placing a conveying bottle is provided at the top of the station 5. The movable conveying pipe 10 reciprocates between the hole and the main conveying pipe 9, and also includes an automatic bottle feeding device.

[0030] Specifically, the moving conveyor pipe can be realized through a gear and rack mechanism: a drive plate is provided on the side of the moving conveyor pipe, a rack 11 is provided on one side of the drive plate, and a gear 12 that meshes with the rack is provided inside the station 5, as well as a motor (not shown in the figure) that drives the gear to rotate forward and backward. In this way, the moving conveyor pipe can be moved back and forth to align with the hole and the main conveyor pipe respectively.

[0031] It is understandable that the reciprocating movement of the moving conveyor pipe can also be achieved in other ways, such as by extending or retracting a cylinder to drive the reciprocating movement of the moving conveyor pipe.

[0032] A first baffle 13 is fixed to the upper side of the mobile conveying pipe 10, and a second baffle 14 is provided on the side of the position where the main conveying pipe and the lower part of the mobile conveying pipe are aligned. When the mobile conveying pipe 10 moves and aligns with the hole on the station 5, the second baffle 14 blocks the bottom of the mobile conveying pipe 10. When the mobile conveying pipe 10 is aligned with the main conveying pipe 9, the first baffle 13 blocks the hole at the top of the station 5. Through the above settings, the conveying bottle can be effectively prevented from leaking out of the hole. In addition, an arc-shaped guide part 15 is fixed on the side of the hole on the station to facilitate the alignment of the conveying bottle with the hole so that the conveying bottle can fall into the mobile conveying pipe 10.

[0033] By setting up an automatic bottle feeding device at the station, when the operator arrives at the station, if there is no conveying task at that time, the operator can directly operate the station to align the moving conveyor pipe with the bottle feeding hole on the station and put the conveyed bottle into the conveyor line. If the previous task has not been completed, the conveyed bottle can be placed at the bottle feeding hole position of the station. In the case of multiple bottles, they can be arranged sequentially on the channel of the bottle feeding device. In this way, when the previous conveyed bottle in the main conveying pipe is completed, the control system controls the moving conveyor pipe to move below the hole position, and the conveyed bottle on the hole falls into the moving conveyor pipe. Then the moving conveyor pipe is aligned with the main conveying pipe, and at the same time the motor drives the drive plate to rotate, pushing the conveyed bottles on the channel forward. The first conveyed bottle will stop at the hole position, waiting for the previous conveying task to be completed, and then the above process is repeated. During the process, the operator does not need to wait at the station, and the work efficiency is higher. The control of the motor driving the moving conveyor pipe and the drive plate rotation motor can be realized by the PLC control system. At the same time, corresponding sensors can also be set on the side of the hole to detect whether there are waiting conveyed bottles. This is a conventional technical means in this field and is not specifically limited here.

[0034] 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.
