DETAILED DESCRIPTION

[0019] like Figure 1-3As shown, a mechanical device for automatically dropping bottles into a pneumatic logistics system for sending includes a main frame 1, a passing tube 2, and a receiving tube 3. A cavity is provided in the main frame 1. The passing tube 2 and the receiving tube 3 are both vertically arranged in the cavity. A first through hole 4 is penetrated at the left end of the top wall of the cavity, and a second through hole 19 is penetrated at the right end of the bottom wall of the cavity. The inner diameter of the first through hole 4 and the inner diameter of the second through hole 19 are both equal to the inner diameter of the passing tube 2. A conveying blocker cooperating with the first through hole 4 is provided at the first through hole 4 on the main frame 1. A driver is provided in the cavity on the main frame 1. The execution end of the driver connects the passing tube 2 and the receiving tube 3. The virtual connecting line segment between the projection of the first through hole 4 on the inner bottom wall of the cavity and the second through hole 19 is L. The path of the passing tube 2 and the receiving tube 3 driven by the driver is consistent with L. Overlapping and with a length greater than or equal to the length of L, an upper through hole 5 and a lower through hole 6 are respectively provided on the top wall and the bottom wall of the cavity on the main frame 1, the upper through hole 5 is coaxial with the second through hole 19, and the lower through hole 6 is located on the side of the second through hole 19 that is away from the projection of the first through hole 4 on the inner bottom wall of the cavity; when the through tube 2 is coaxial with the second through hole 19, the receiving tube 3 is coaxial with the lower through hole 6; a first sensor 7 is provided in the through tube 2, and the signal of the first sensor 7 is connected to the driver; the driver controls the connection to the conveying blocker, and when the driver drives the through tube 2 to move to be coaxial with the first through hole 4, the conveying blocker does not block the passage of objects in the first through hole 4; when the driver drives the through tube 2 to move to be coaxial with the second through hole 19, the conveying blocker will block the passage of objects in the first through hole 4.

[0020] In this embodiment, in the initial state, the baffle 9 is in the first through hole 4, and the transmission bottle A is manually placed in the placement tube. At this time, the baffle 9 prevents the transmission bottle A from falling. When the driver drives the through tube 2 to be coaxial with the upper through hole 5 and the second through hole 19, the transmission bottle B in the system transmission tube A (not shown in the figure) can be transported to the lower end of the main frame 1 after passing through the upper through hole 5, the through tube 2 and the second through hole 19. In actual application, the second through hole 19 is connected to the lower end of the main frame 1 through the system transmission tube B (not shown in the figure). At this time, the system transmission tube A and the system transmission tube B are connected, and the transmission bottle B can be transported normally. When it is necessary to automatically put the transmission bottle A in the placement tube 8 into the system transmission tube B, the driver drives the whole body consisting of the through tube 2 and the receiving tube 3 to move to the through tube 2 and the first through hole 4, and then the driver drives the conveying blocker to open, and the transmission bottle A freely falls into the through tube 2. After the first sensor 7 detects the signal, it transmits the signal to the driver, and the driver drives the whole body consisting of the through tube 2 and the receiving tube 3 to move to the through tube 2 and the second through hole 19 and stops, and the transmission bottle A falls from the second through hole 19 into the system transmission tube B, completing the purpose of the transmission bottle A entering the entire transmission system. Due to the setting of the receiving tube 3, when the receiving tube 3 is coaxial with the second through hole 19, the transmission bottle in the system transmission tube B can receive the transmission bottle into the receiving tube 3 through the structure in the receiving tube 3, and the purpose of the lower through hole 6 is to move the transmission bottle received in the receiving tube 3 out of the entire transmission system. When the driver drives the receiving tube 3 to move to the coaxial position with the lower through hole 6, the transmission bottle in the receiving tube 3 falls out of the entire transmission system from the lower through hole 6, thereby completing the purpose of receiving the transmission bottle from the entire transmission system.

[0021] As a preferred mode, a placement tube 8 is coaxially provided on the bottom wall of the main frame 1 at the first through hole 4, and the inner diameter of the placement tube 8 is equal to the inner diameter of the first through hole 4. In this way, by providing the placement tube 8, it is convenient to put the transmission bottle outside the transmission system into the sending device, so as to prepare for the transmission bottle to enter the entire transmission system.

[0022] As a preferred embodiment, the conveying blocker includes a baffle 9, a tension spring 10, a limiting column 11, and a lever 12. A vertical rotating shaft 13 is provided on the main frame 1 next to the first through hole 4. One end of the baffle 9 is rotatably connected to the main frame 1 through the rotating shaft 13. The connecting line segment between the rotating shaft 13 and the first through hole 4 has an angle with L, and the angle is between 0-180°. When the baffle 9 rotates around the rotating shaft 13, the end of the baffle 9 away from the rotating shaft 13 can be rotated to just above the first through hole 4. One end of the tension spring 10 is fixedly connected to the upper surface of the main frame 1, and the other end of the tension spring 10 is fixedly connected to the two ends of the baffle 9. The limiting column 11 is vertically arranged On the main frame 1, one end of the tension spring 10 fixedly connected to the main frame 1 is located on the side of the limit column 11 facing away from the baffle 9; when the baffle 9 is tightly attached to the limit column 11 under the action of the tension spring 10, the free end of the baffle 9 is located directly above the first through hole 4; the shift rod 12 is fixedly connected to the execution end of the driver; when the driver drives the through tube 2 to move to a position coaxial with the first through hole 4, the shift rod 12 shifts the baffle 9 to a position deviating from directly above the first through hole 4; when the driver drives the through tube 2 to move to a position coaxial with the second through hole 19, the shift rod 12 leaves the baffle 9 and the free end of the baffle 9 is located directly above the first through hole 4.

[0023] After such arrangement, when the baffle plate 9 is located directly above the first through hole 4, it blocks the transmission bottle A in the placement tube 8 from entering the main frame 1. When the driver drives the through tube 2 to move to a position coaxial with the first through hole 4, the lever 12 shifts the baffle plate 9 to a position deviating from directly above the first through hole 4, and the transmission bottle A in the placement tube 8 passes through the first through hole 4 and falls into the through tube 2. When the driver drives the through tube 2 to leave the first through hole 4, the lever 12 no longer contacts the baffle plate 9, and the baffle plate 9 is moved to a position directly above the first through hole 4 under the action of the tension spring 10, thereby blocking the transmission bottle A in the placement tube 8 from entering the main frame 1. The setting of the limit column 11 is mainly to prevent the tension spring 10 from acting too much, and to play a buffering role when the baffle plate 9 does not deviate from the hole of the first through hole 4.

[0024] As a preferred method, Figure 3 As shown, the lower end of the lever 12 is fixedly connected to the execution end of the driver, the upper end of the lever 12 is located on the side of the baffle 9 facing the tension spring 10 and the upper end of the lever 12 is located on the side of the rotating shaft 13 facing the free end of the baffle 9. After this arrangement, the lever 12 can move the baffle 9 during the movement without affecting the normal operation of the conveying blocker.

[0025] As a preferred embodiment, the driver includes a servo motor 14, a gear 15, and a rack 16. The servo motor 14 is fixed on the main frame 1. The gear 15 is coaxially fixed on the output shaft of the servo motor 14. The rack 16 is fixedly connected to the through tube 2 and the receiving tube 3. The circumferential surface of the gear 15 is meshed with the teeth arranged on the plane of the rack 16 which is parallel to L and the axis of the through tube 2. The through tube 2 and the receiving tube 3 are both slidably connected to the cavity through a sliding connector. The axis of the gear 15 is parallel to the axis of the through tube 2. The rack 16 is parallel to the inner bottom wall of the cavity. The signal of the first sensor 7 is connected to the servo motor 14. The rack 16 is fixedly connected to the lower end of the shift rod 12.

[0026] After such arrangement, the gear 15 is driven to rotate by the servo motor 14, thereby driving the rack 16 to move, thereby driving the passing tube 2, the receiving tube 3 and the shifting rod 12 to move.

[0027] As a preferred embodiment, the sliding connector includes a guide rail 17 and a fixing plate 18. The guide rail 17 is arranged in the cavity, the guide rail 17 is parallel to the L, the fixing plate 18 is slidably connected to the main frame 1 through the guide rail 17, and the fixing plate 18 is fixedly connected to the through tube 2 and the receiving tube 3. In this way, after the guide rail 17 and the fixing plate 18 are arranged, the movement direction of the through tube 2 and the receiving tube 3 is prevented from being offset.

[0028] Preferably, a second sensor 20 is provided on the receiving tube 3, and the signal of the second sensor 20 is connected to the driver. When the transmission bottle in the system transmission tube B is ready to receive, the driver drives the receiving tube 3 to move to be coaxial with the second through hole 19, and the transmission bottle to be received is pushed into the receiving tube 3 by the airflow in the system, and the signal of the second sensor 20 is connected to the driver again. When the driver drives the receiving tube 3 to move to be coaxial with the lower through hole 6, the transmission bottle falls out of the entire transmission system from the lower through hole 6.
