Description

Technical Field

[0001] This application belongs to the field of pneumatic logistics transmission, and specifically relates to a device for receiving and sending transmission bottles in the pipeline of a pneumatic logistics system. Background Art

[0002] In the design of a pneumatic logistics transmission system, only one transmission bottle can be transmitted simultaneously within the same fan system; to improve the system usage efficiency, generally no more than 15 stations are set within the same fan system. A general pneumatic logistics transmission system project is generally composed of multiple fan systems. When stations in different fan systems send and receive transmission bottles to each other, through the interconnection of the outlet pipes of the two sets of fan system commutators, the sending-end fan sends the transmission bottle and temporarily stores it in the interconnection pipe, waiting for the receiving-end fan to send the transmission bottle in the temporary storage pipe to the target station. The limitation of this solution is that only one transmission bottle can be temporarily stored in each group of interconnection pipes. When the receiving-side fan is busy, the sending end cannot send bottles across fan systems. If the number of interconnected pipes is increased, the number of system commutators will increase, greatly increasing the system cost. Summary of the Utility Model

[0003] The main purpose of this application is to address the shortcomings of the prior art. By setting a receiving and sending switch and upper and lower sensors between the two ends of a vertically arranged pipeline, a device for receiving and sending transmission bottles in the pipeline of a pneumatic logistics system is designed. It can receive bottles, use gravity to send the bottles into the interconnection pipe, and then be sent to the target station by the receiving-end fan. As long as the building floor height permits, each additional set of this device can store one more bottle for cross-region transmission. In this way, the number of transmission bottles stored in the fan interconnection pipe is increased at a relatively low cost, the idle time of the fan is reduced, and the transmission efficiency of the entire pneumatic logistics system is greatly improved, solving the problem that only one transmission bottle can be temporarily stored in each current group of interconnection pipes, resulting in a long fan restriction time and low transmission efficiency.

[0004] To achieve the above purpose, the technical solution adopted in this application is:

[0005] A device for receiving and sending transmission bottles in the pipeline of a pneumatic logistics system, including a pipeline, a receiving and sending switch, an upper sensor, and a lower sensor. The receiving and sending switch is arranged between the upper and lower ends of the pipeline. The upper sensor and the lower sensor are respectively arranged on the side wall of the pipeline on the upper and lower sides of the receiving and sending switch. A preset distance is set between the upper sensor and the receiving and sending switch, and a preset distance is set between the lower sensor and the receiving and sending switch. Both the upper sensor and the lower sensor are signal-connected to the receiving and sending switch.

[0006] Preferably, the transceiver switch includes a mounting plate, a switch plate, a control motor, and a chip control circuit board. The mounting plate has a hollow structure inside. The switch plate is located inside the hollow structure of the mounting plate and is parallel to the front surface of the mounting plate. The mounting plate is provided with a through hole whose axis is perpendicular to the switch plate. The two ends of the pipeline are hermetically connected to the hollow structure. The control motor is arranged on the mounting plate, and the output shaft of the control motor is drivingly connected to the hollow structure. When the control motor drives the switch plate to move away from the pipeline inside the hollow structure, the switch plate can be completely separated from the pipeline. When the control motor drives the switch plate to move towards the pipeline inside the hollow structure, at least part of the switch plate can be radially inserted into the pipeline. Both the upper sensor and the lower sensor are signal-connected to the input end of the chip control circuit board, and the output end of the chip control circuit board is signal-connected to the control motor.

[0007] Preferably, when the control motor drives the switch plate to move towards the pipeline inside the hollow structure, the two ends of the switch plate can penetrate between the two ends of the pipeline.

[0008] Preferably, the pipeline includes an upper pipeline and a lower pipeline. Both ends of the upper pipeline are open, and both ends of the lower pipeline are open. The lower end of the upper pipeline is fixedly connected at the through hole on the front surface of the mounting plate. The end of the upper pipeline fixedly connected to the front surface of the mounting plate is coaxial with the through hole. The upper end of the lower pipeline is fixedly connected at the through hole on the back surface of the mounting plate. The end of the lower pipeline fixedly connected to the back surface of the mounting plate is coaxial with the through hole. The upper sensor is installed on the side wall of the upper pipeline, and the lower sensor is installed on the side wall of the lower pipeline.

[0009] Preferably, the projection of the hollow structure on the front surface of the mounting plate is a rectangle. The projection of the through hole on the front surface of the mounting plate is inside the rectangle. The length of the switch plate is less than or equal to the length of the rectangle, and the width of the switch plate is equal to or less than the width of the rectangle. When the switch plate is completely located between the two ends of the through hole, the projection of the switch plate on the front surface of the mounting plate surrounds the projection of the through hole on the front surface of the mounting plate. A preset distance is provided between the through hole and the geometric center of the rectangle.

[0010] Preferably, the width of the switch plate is equal to the width of the rectangle, and the length of the switch plate is less than half of the length of the rectangle.

[0011] Preferably, the control motor is arranged on the front surface of the mounting plate away from the pipeline. The output shaft of the control motor extends into the hollow structure. A notch is arranged at one end of the upper surface of the switch plate facing the control motor. The length line of the notch is perpendicular to the length line of the rectangle. A driving rod is radially fixed on the output shaft of the control motor. A shifting shaft is fixed at one end of the driving rod away from the control motor. The shifting shaft is perpendicular to the front surface of the mounting plate. One end of the shifting shaft is inserted into the notch, and the shifting shaft is slidably connected with the notch. The length of the notch is greater than the length of the driving rod and less than the width of the switch plate. When the driving rod is located on the side of the control motor facing the through hole, at least part of the switch plate is located directly below the through hole. When the driving rod is located on the side of the control motor facing away from the through hole, the switch plate completely leaves directly below the through hole.

[0012] Compared with the prior art, the present application has the following beneficial effects:

[0013] 1. The present application adopts the method of arranging a transceiver switch and upper and lower sensors between the two ends of a vertically arranged pipeline to design a device for receiving and transmitting bottles in the pipeline of a pneumatic logistics system. It can receive bottles, use gravity to send the bottles into the interconnected pipeline, and then send them to the target site by the receiving end fan. As long as the building floor height permits, each additional set of this device can store one more bottle for cross-region transmission. In a relatively low-cost way, this device increases the number of bottles stored and transmitted in the fan interconnected pipeline, reduces the idle time of the fan, and greatly improves the transmission efficiency of the entire pneumatic logistics system, solving the problem that only one transmission bottle can be temporarily stored in each current interconnected pipeline, resulting in a long fan restriction time and low transmission efficiency.

[0014] 2. The switch plate in the present application can slide in the hollow structure of the mounting plate. When the switch plate slides directly below the through hole, it is in a situation of blocking between the two ends of the pipeline, that is, the closed state. When the switch plate slides away from directly below the through hole, at this time the bottle can be transported in the pipeline, that is, the transceiver switch is in the open state. The control motor is used to drive the switch plate to move in the hollow structure. The upper sensor and the lower sensor are used to sense whether there is a bottle in the pipeline. When the upper sensor detects a signal of a bottle at this position, the chip control circuit board sends a signal to the control motor to open the switch plate in the pipeline, so that the switch plate leaves the through hole. After the lower sensor detects the signal of the bottle, the chip control circuit board sends a signal to the control motor to close the switch plate in the pipeline, so that the switch plate is at the through hole and blocks the through hole. The rotation direction of the output shaft of the control motor in this process is opposite to the rotation direction of the output shaft of the control motor in the process of opening the switch plate.

[0015] 3. In the present application, by setting the two ends of the switch plate to be able to completely penetrate between the two ends of the pipeline in the closed state, when the switch plate is closed, the through-hole is completely blocked, thereby preventing the bottle from passing through the gap between the switch plate and the inner wall of the through-hole.

[0023] As Figures 1-6 shown, a device for receiving and transmitting bottles in a pneumatic logistics system pipeline includes a pipeline, a transceiver switch, an upper sensor 1, and a lower sensor 2. The transceiver switch is arranged between the upper and lower ends of the pipeline. The upper sensor 1 and the lower sensor 2 are respectively arranged on the side wall of the pipeline on the upper and lower sides of the transceiver switch. A preset distance is set between the upper sensor 1 and the transceiver switch, and a preset distance is set between the lower sensor 2 and the transceiver switch. Both the upper sensor 1 and the lower sensor 2 are signal-connected to the transceiver switch.

[0024] In the present application, in the initial state, the transceiver switch is in the closed state, isolating the two ends of the pipeline. When the bottle 13 is conveyed from the upper pipeline and collides with the transceiver switch and is blocked and stops in the pipeline. At this time, the upper sensor 1 detects the signal of the bottle 13 at this position and sends this signal to the transceiver switch. The transceiver switch judges whether to open according to the preset requirements, so as to complete whether to convey.

[0025] As a preferred embodiment, the transceiver switch includes a mounting plate 3, a switch plate 4, a control motor 5, and a chip control circuit board 6 (a PLC controller can be used, and a servo motor can be used for the control motor 5). The mounting plate 3 is provided with a hollow structure. The switch plate 4 is located within the hollow structure of the mounting plate 3 and is parallel to the front surface of the mounting plate 3. The mounting plate 3 is provided with a through hole 7 whose axis is perpendicular to the switch plate 4. The two ends of the pipeline are hermetically connected to the hollow structure. The control motor 5 is arranged on the mounting plate 3, and the output shaft of the control motor 5 is drivingly connected to the hollow structure. When the control motor 5 drives the switch plate 4 to move away from the pipeline within the hollow structure, the switch plate 4 can be completely separated from the pipeline. When the control motor 5 drives the switch plate 4 to move towards the pipeline within the hollow structure, at least a part of the switch plate 4 can be radially inserted into the pipeline. Both the upper sensor 1 and the lower sensor 2 are signal-connected to the input end of the chip control circuit board 6, and the output end of the chip control circuit board 6 is signal-connected to the control motor 5.

[0026] After such a setting, the switch plate 4 can slide within the hollow structure of the mounting plate 3. When the switch plate 4 slides to directly below the through hole 7, the two ends of the pipeline are blocked, that is, in the closed state. When the switch plate 4 slides away from directly below the through hole 7, at this time, the bottle 13 can be conveyed within the pipeline, that is, the transceiver switch is in the open state. The control motor 5 is used to drive the switch plate 4 to move within the hollow structure. The upper sensor 1 and the lower sensor 2 are used to detect whether there is a bottle 13 within the pipeline. When the upper sensor 1 detects a signal of the bottle 13 at this position, the chip control circuit board 6 sends a signal to the control motor 5 to open the switch plate 4 within the pipeline, so that the switch plate 4 moves away from the through hole 7. After the lower sensor 2 detects the signal of the bottle 13, the chip control circuit board 6 sends a signal to the control motor 5 to close the switch plate 4 within the pipeline, so that the switch plate 4 is located at the through hole 7 to block the through hole 7. During this process, the rotation direction of the output shaft of the control motor 5 is opposite to the rotation direction of the output shaft of the control motor 5 during the process of opening the switch plate 7.

[0027] As a preferred embodiment, when the control motor 5 drives the switch plate 4 to move towards the pipeline within the hollow structure, the space between the two ends of the switch plate 4 can penetrate between the two ends of the pipeline. In this way, when the switch plate 4 is closed, the through hole 7 is completely blocked, thereby preventing the bottle from passing through the gap between the switch plate 4 and the inner wall of the through hole 7 during the conveyance of some smaller-sized bottles 13.

[0028] As a preferred embodiment, the pipeline includes an upper pipeline 8 and a lower pipeline 9. Both ends of the upper pipeline 8 are open, and both ends of the lower pipeline 9 are open. The lower end of the upper pipeline 8 is fixedly connected at the through hole 7 on the front surface of the mounting plate 3. One end of the upper pipeline 8 fixedly connected to the front surface of the mounting plate 3 is coaxial with the through hole 7. The upper end of the lower pipeline 9 is fixedly connected at the through hole 7 on the back surface of the mounting plate 3. One end of the lower pipeline 9 fixedly connected to the back surface of the mounting plate 3 is coaxial with the through hole 7. The upper sensor 1 is installed on the side wall of the upper pipeline 8, and the lower sensor 2 is installed on the side wall of the lower pipeline 9.

[0029] In this way, the method of dividing the pipeline into the upper pipeline 8 and the lower pipeline 9 facilitates installation and subsequent maintenance.

[0030] As a preferred embodiment, the projection of the hollow structure on the front surface of the mounting plate 3 is rectangular. The projection of the through hole 7 on the front surface of the mounting plate 3 is within the rectangle. The length of the switch plate 4 is less than or equal to the length of the rectangle, and the width of the switch plate 4 is equal to or less than the width of the rectangle. When the switch plate 4 is completely located between the two ends of the through hole 7, the projection of the switch plate 4 on the front surface of the mounting plate 4 surrounds the projection of the through hole 7 on the front surface of the mounting plate 3. A preset distance is provided between the through hole 7 and the geometric center of the rectangle.

[0031] After such a setting, during the process of controlling the rotation of the motor 5, the switch plate 4 is pulled to move within the hollow structure. The preset distance between the through hole 7 and the geometric center of the rectangle enables the switch plate 4 to completely not block the through hole 7 when the switch plate 4 is located at the end of the hollow structure far from the through hole 7.

[0032] As a preferred embodiment, the width of the switch plate 4 is equal to the width of the rectangle, and the length of the switch plate 4 is less than half of the length of the rectangle. This setting method avoids the switch plate 4 from shaking within the hollow structure.

[0033] As a preferred manner, the control motor 5 is disposed on the front surface of the mounting plate 3 away from the pipeline. The output shaft of the control motor 5 extends into the hollow structure. A notch 10 is provided at one end of the upper surface of the switch plate 4 facing the control motor 5. The length line of the notch 10 is perpendicular to the length line of the rectangle. A driving rod 11 is radially fixed on the output shaft of the control motor 5. A dial shaft 12 is fixedly provided at one end of the driving rod 11 away from the control motor 5. The dial shaft 12 is perpendicular to the front surface of the mounting plate 3. One end of the dial shaft 12 is inserted into the notch 10. The dial shaft 12 is slidably connected with the notch 10. The length of the notch 10 is greater than the length of the driving rod 11 and less than the width of the switch plate 4. When the driving rod 11 is on the side of the control motor 5 facing the through hole 7, at least a part of the switch plate 4 is located directly below the through hole 7. When the driving rod 11 is on the side of the control motor 5 facing away from the through hole 7, the switch plate 4 completely leaves directly below the through hole 7.

[0034] After such a setting, the control motor 5 rotates, causing the driving rod 11 to rotate together. During the rotation of the driving rod 11, the dial shaft 12 is driven to rotate. The dial shaft 12 slides relative to the chute 10, thereby driving the switch plate 4 to move within the hollow structure. The function of the switch is realized.
