Description

Technical Field

[0001] This utility model belongs to the field of pharmaceutical processing equipment, specifically relating to a discharging blister pack flipping device. Background Technology

[0002] With the continuous development of technology, in the pharmaceutical packaging production process, drug granules are first quantitatively placed into the recesses of a plastic tray (blister pack). Then, an aluminum foil heat-sealing machine or a blister pack heat-sealing machine is used to heat-seal the aluminum foil onto the tray surface, forming a complete blister pack unit. After heat sealing, the blister pack is usually output to the conveyor belt with the aluminum foil facing upwards. However, subsequent visual inspection processes (such as missing granule detection and seal integrity detection) require the blister pack to be in an aluminum foil-down position to ensure accurate identification by the detection system. Currently, two main flipping methods are used on the production line: one is manual flipping, which is not only inefficient (only 10-15 blister packs can be processed per minute) but also poses a risk of contamination; the other is a mechanical gripper flipping mechanism, which, although highly automated, has a complex equipment structure, high maintenance costs, and the grippers are prone to tearing the aluminum foil on the blister pack surface during high-speed operation. Therefore, the existing technology suffers from the problems of low efficiency in manual flipping and the risk of tearing the aluminum foil on the blister pack surface during mechanical gripper flipping. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a discharging medicine plate turning device, which solves the problems of low efficiency of manual turning and easy tearing of the aluminum film on the surface of the medicine plate when mechanical grippers turn it.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A discharging blister pack flipping device includes a first conveyor and a second conveyor for conveying blister packs;

[0006] A horizontally placed rotating shaft is provided between the first conveyor and the second conveyor;

[0007] The upper surface of the first conveyor is higher than the central axis of the rotating shaft, and the upper surface of the second conveyor is lower than the central axis of the rotating shaft.

[0008] Multiple strip-shaped connecting plates are fixed radially on the peripheral wall of the rotating shaft, and a receiving groove for accommodating medicine plates is formed between two adjacent connecting plates;

[0009] A first drive assembly is connected to the rotating shaft, and the first drive assembly is used to drive the rotating shaft to rotate around its own axis.

[0010] Before the blister pack is flipped, any of the receiving tanks is placed at an angle upward from the rotating shaft to the first conveyor end. The first conveyor is used to transport the blister pack into the receiving tank.

[0011] Both the first and second conveyors are belt conveyors;

[0012] Both the first and second conveyors include a base frame, on which a pair of horizontally placed rollers are rotatably connected. An annular conveyor belt is fitted between the two rollers, and a second drive assembly for driving either roller to rotate is installed on the base frame.

[0013] The rollers and shaft of the first conveyor are placed coaxially.

[0014] Multiple connecting plates on the rotating shaft are evenly distributed in a ring around the central axis of the rotating shaft;

[0015] When the first drive component is turned on, the drive shaft rotates continuously 360° in a single direction.

[0016] The first drive assembly includes a pair of support plates fixed on the base frame of the second conveyor. The two ends of the rotating shaft are rotatably connected to the two support plates respectively. A first rotating motor is installed on either support plate, and the output end of the first rotating motor is coaxially fixed with the rotating shaft.

[0017] There are two connecting plates on the rotating shaft;

[0018] When the first drive component is turned on, the drive shaft swings back and forth 180° around its own axis.

[0019] When the two connecting plates swing to tilt downwards toward the second conveyor, the bottom of the lower connecting plate is close to the upper surface of the annular conveyor belt of the second conveyor.

[0020] The first drive assembly includes a pair of support plates fixed on the base frame of the second conveyor. The two ends of the rotating shaft are rotatably connected to the two support plates respectively. A gear is fixedly sleeved on either end of the rotating shaft, and a spur rack meshes on the gear. A drive unit is fixedly installed on the support plate near the gear. The drive unit is fixedly connected to the spur rack and is used to drive the spur rack to perform reciprocating linear motion along its own axis.

[0021] The drive unit includes a telescopic cylinder, the piston rod of which is placed coaxially with the rack. The piston rod of the telescopic cylinder is fixedly connected to the rack, and when the piston rod of the telescopic cylinder moves from the fully retracted state to the fully extended state, the rack drives the gear to rotate 180°.

[0022] The annular conveyor belt of the first conveyor has a rough textured layer on the side away from the rotating roller.

[0023] The beneficial effects of this utility model are:

[0024] 1. Through the coordinated arrangement of the rotating shaft, connecting plate and first drive assembly, the medicine plate is transferred from the first conveyor to the second conveyor and enters the receiving groove of the two adjacent connecting plates. The rotating shaft drives the receiving groove to rotate and flip, realizing the automatic flipping operation of the medicine plate, so that the aluminum film of the medicine plate is placed face down, so as to facilitate the subsequent detection of whether there is medicine in the medicine plate.

[0025] Furthermore, multiple medicine plates placed along the shaft axis on the first conveyor can enter the same receiving tank, enabling the flipping of multiple medicine plates each time, thus improving the efficiency of medicine plate flipping and avoiding the problem of tearing the aluminum film on the surface of the medicine plates during the flipping process.

[0026] 2. In Embodiment 1 of this application, the arrangement of multiple connecting plates evenly distributed in a ring around the central axis of the rotating shaft, combined with the drive of the first rotating motor, enables the rotating shaft to rotate continuously 360° in a single direction, which is suitable for the flipping operation in the high-efficiency production and processing of pharmaceutical blister packs.

[0027] 3. In Embodiment 2 of this application, the setting of two connecting plates, in conjunction with the first driving component, drives the rotating shaft to reciprocate around its own axis by 180°, which effectively reduces the falling height of the medicine plate in the receiving tank when it is released onto the second conveyor, and reduces the possibility of the medicine plate shifting or accidentally overturning during free fall.

[0028] At the same time, it effectively reduces the risk of damage to the internal drugs caused by the impact of the falling blister pack, especially fragile drugs such as tablets or capsules. It can significantly reduce the risk of breakage caused by collision or vibration during the transfer process, ensuring the integrity and quality safety of the drugs inside the blister pack.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figures 1 to 4 As shown, a discharging medicine plate turning device includes a first conveyor 100 and a second conveyor 200 for conveying medicine plates;

[0036] A horizontally placed rotating shaft 300 is provided between the first conveyor 100 and the second conveyor 200;

[0037] The upper surface of the first conveyor 100 is higher than the central axis of the rotating shaft 300, and the upper surface of the second conveyor 200 is lower than the central axis of the rotating shaft 300.

[0038] Multiple strip-shaped connecting plates 301 are fixed radially on the circumferential wall of the rotating shaft 300, and a receiving groove 302 for accommodating medicine plates is formed between two adjacent connecting plates 301.

[0039] A first drive assembly 400 is connected to the rotating shaft 300, and the first drive assembly 400 is used to drive the rotating shaft 300 to rotate around its own axis.

[0040] Before the blister pack is flipped, any of the receiving tanks 302 is placed at an angle upward from the rotating shaft 300 toward the end of the first conveyor 100. The first conveyor 100 is used to transport the blister pack into the receiving tank 302.

[0041] It should be noted that this application is used in conjunction with the aluminum foil heat sealing machine or blister packaging heat sealing machine in the prior art. The aluminum foil heat sealing machine or blister packaging heat sealing machine is used to cover the tray containing the tablets with aluminum film, and the tray and aluminum film together form a tablet blister.

[0042] During production and processing, the aluminum foil heat sealing machine or blister packaging heat sealing machine is located at the end of the first conveyor 100 away from the rotating shaft 300, and discharges the medicine blister produced by it onto the first conveyor 100. Multiple medicine blister are produced at the same time, and the multiple medicine blister are distributed at equal intervals along the axial direction of the rotating shaft 300. The aluminum film in the medicine blister entering the first conveyor 100 is placed with the aluminum foil facing upward.

[0043] The first conveyor 100 transports the blister pack into any of the receiving slots 302. Then, the first drive assembly 400 is activated, driving the rotating shaft 300 to rotate the receiving slot 302 holding the blister pack upwards until the receiving slot 302 rotates to a tilted downward position towards the second conveyor 200 from the rotating shaft 300. The blister pack slides out from the receiving slot 302 onto the second conveyor 200, realizing the automatic flipping operation of the blister pack, so that the aluminum film of the blister pack is placed downwards, which is convenient for subsequent detection of whether there are any pills in the blister pack.

[0044] Furthermore, multiple medicine plates placed axially along the rotating shaft 300 on the first conveyor 100 can enter the same receiving tank 302, realizing the flipping operation of multiple medicine plates each time, thereby improving the efficiency of medicine plate flipping operation.

[0045] Both the first conveyor 100 and the second conveyor 200 are belt conveyors;

[0046] Both the first conveyor 100 and the second conveyor 200 include a base frame 101. A pair of horizontally placed rollers 102 are rotatably connected to the base frame 101. An annular conveyor belt 103 is sleeved between the two rollers 102. A second drive assembly 104 for driving either roller 102 to rotate is installed on the base frame 101.

[0047] In the first conveyor 100, the rotating roller 102 is placed coaxially with the rotating shaft 300;

[0048] Preferably, each of the second drive components 104 includes a second rotating motor and a sprocket assembly. The second rotating motor is fixedly mounted on the base frame 101. The sprocket assembly includes a pair of sprockets and a chain. One sprocket is fixedly sleeved on the output shaft of the second rotating motor, and the other sprocket is fixedly sleeved on any of the rotating rollers 102. The two sprockets are connected by a chain.

[0049] The second rotating motor drives the sprocket on its output shaft, and the sprocket assembly drives the rotating roller 102 to rotate, which in turn drives the annular conveyor belt 103 to transport the medicine plate.

[0050] This application provides two different embodiments of the first drive component 400;

[0051] Example 1

[0052] Multiple connecting plates 301 on the rotating shaft 300 are evenly distributed in a ring around the central axis of the rotating shaft 300;

[0053] When the first drive assembly 400 is turned on, the drive shaft 300 rotates continuously 360° in a single direction; so that each receiving slot 302 sequentially receives the medicine plate on the first conveyor 100, and after flipping, releases it above the second conveyor 200;

[0054] Preferably, the number of connecting plates 301 is 6 or 8;

[0055] The first drive assembly 400 includes a pair of support plates 401 fixed on the base frame 101 of the second conveyor 200. The two ends of the rotating shaft 300 are rotatably connected to the two support plates 401 respectively. A first rotating motor 402 is installed on either support plate 401. The output end of the first rotating motor 402 is coaxially fixed with the rotating shaft 300. The rotating shaft 300 is driven by the first rotating motor 402 to rotate continuously 360° in a single direction, which is suitable for the flipping operation in the high-efficiency production and processing of pharmaceutical blister packs.

[0056] Example 2

[0057] There are two connecting plates 301 on the rotating shaft 300;

[0058] When the first drive assembly 400 is turned on, the drive shaft 300 reciprocates 180° around its own axis, causing the receiving tank 302 to alternate between receiving the medicine blister pack on the first conveyor 100 and releasing the medicine blister pack onto the second conveyor 200.

[0059] During the reciprocating swing, only one receiving slot 302 is used to receive the medicine plate, that is, only two connecting plates 301 are needed;

[0060] When the two connecting plates 301 swing to tilt downward toward the second conveyor 200, the bottom of the lower connecting plate 301 is close to the upper surface of the annular conveyor belt 103 of the second conveyor 200.

[0061] In Embodiment 1, a gap needs to be reserved between the upper surface of the second conveyor 200 and the rotating shaft 300 for the connecting plate 301 to pass through during rotation. In Embodiment 2, the connecting plate 301 is mostly above the central axis of the rotating shaft 300 during reciprocating swing, and only when the two connecting plates 301 swing to tilt downwards towards the second conveyor 200 does the end of the connecting plate 301 away from the rotating shaft 300 tilt downwards to below the central axis of the rotating shaft 300. Therefore, compared with Embodiment 1, Embodiment 2 has a smaller distance between the central axis of the rotating shaft 300 and the upper surface of the second conveyor 200. This effectively reduces the falling height of the medicine slab in the receiving tank 302 when it is released onto the second conveyor 200, reducing the possibility of the medicine slab shifting or accidentally overturning during free fall.

[0062] At the same time, it effectively reduces the risk of damage to the internal drugs caused by the impact of the falling of the blister pack, especially fragile drugs such as tablets or capsules. It can significantly reduce the risk of breakage caused by collision or vibration during the transfer process, ensuring the integrity and quality safety of the drugs inside the blister pack.

[0063] The first drive assembly 400 includes a pair of support plates 401 fixed on the base frame 101 of the second conveyor 200. The two ends of the rotating shaft 300 are rotatably connected to the two support plates 401 respectively. A gear 403 is fixedly sleeved on either end of the rotating shaft 300. A rack 404 meshes on the gear 403. A drive unit 405 is fixedly installed on the support plate 401 near the gear 403. The drive unit 405 is fixedly connected to the rack 404 and is used to drive the rack 404 to perform reciprocating linear motion along its own axis.

[0064] Preferably, the support plate 401 has a mounting hole that is coaxial with the rotating shaft 300. Bearings are provided between the rotating shaft 300 and the support plate 401. The inner ring of the bearing is fixed to the peripheral wall of the rotating shaft 300, and the outer ring of the bearing is fixed to the peripheral wall of the mounting hole.

[0065] The gear 403 and the rack 404 are configured to control the reciprocating swing angle of the rotating shaft 300 and the connecting plate 301.

[0066] The drive unit 405 includes a telescopic cylinder. The piston rod of the telescopic cylinder and the rack 404 are placed coaxially. The piston rod of the telescopic cylinder and the rack 404 are fixedly connected. When the piston rod of the telescopic cylinder moves from the fully retracted state to the fully extended state, the rack 404 drives the gear 403 to rotate 180°. Through the reciprocating telescopic movement of the piston rod of the telescopic cylinder, the rack 404 is driven to perform reciprocating linear motion. The rack 404 drives the gear 403, thereby precisely controlling the rotating shaft 300 and the connecting plate 301 to reciprocate.

[0067] Preferably, the telescopic cylinder is fixed to the support plate 401 via a fixed seat;

[0068] Preferably, the telescopic cylinder in this application can also be replaced by an electric push rod or the like.

[0069] Preferably, the first drive unit 405 is also provided with a solenoid valve, which is used to control the opening or closing of the telescopic cylinder or the first rotary motor 402.

[0070] Preferably, in this application, a detection unit 500 is installed on the base frame 101 of the first conveyor 100. The detection unit 500 is used to detect whether there is a medicine plate near the rotating shaft 300 on the first conveyor 100. The signal output terminal of the detection unit 500 is connected to the PLC controller through a shielded wire. The output terminal of the PLC controller is electrically connected to the solenoid valve of the first drive unit 405 through a relay module. When the detection unit 500 detects that the medicine plate has entered the preset trigger area, the PLC controller starts the first drive unit 400 according to the preset program.

[0071] Preferably, the detection unit 500 includes an infrared sensor, a proximity switch, or a photoelectric sensor.

[0072] In order to improve the stability and positioning accuracy of the medicine blister conveyor and avoid the relative sliding between the medicine blister and the annular conveyor belt 103, which would lead to disordered arrangement, the annular conveyor belt 103 of the first conveyor 100 is provided with a rough textured layer 1031 on the side away from the roller 102.
