Description

Technical Field

[0001] This invention belongs to the field of bottled pharmaceutical processing, and specifically relates to a medicine bottle unloading device and method. Background Technology

[0002] Bottled medicine processing generally involves steps such as filling, sealing, and printing. Before filling, empty bottles need to be removed from trays. Currently, empty bottle unloading is done manually, with workers removing each empty bottle from the tray one by one. This is labor-intensive, inefficient, and severely impacts the processing efficiency of bottled medicines. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention aims to provide a medicine bottle unloading device. The device first flips the tray and medicine bottle upside down, making it easier to remove the tray quickly. Then, it flips the tray again in the opposite direction to quickly and upright the medicine bottle. This effectively improves the efficiency of unloading medicine bottles, saves manpower, and thus improves the overall processing quality and efficiency of bottled medicines.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A medicine bottle unloading device includes a feeding mechanism, a feeding mechanism, a tilting mechanism, a discharging mechanism, and a tray-retrieving mechanism. The tilting mechanism is located between the discharge end of the feeding mechanism and the inlet end of the discharging mechanism. The feeding mechanism is installed above the tilting mechanism, and the tray-retrieving mechanism is installed on one side of the tilting mechanism. The tilting mechanism includes a support, a tilting frame, and a rotary motor. The tilting frame is rotatably mounted on the support and driven to rotate by the rotary motor. The feeding mechanism includes a first scraper assembly for feeding material from the tilting mechanism to the discharging mechanism and a second scraper assembly for feeding material from the feeding mechanism to the tilting mechanism. The tray-retrieving mechanism includes a drive assembly and a suction cup. The suction cup for gripping the tray is installed at the actuating end of the drive assembly.

[0006] Preferably, the tilting frame includes two side plates arranged correspondingly at the front and rear, the two side plates are rotatably mounted on the support at the middle, and the rotation axis of one of the side plates is powered by a rotary motor; two vertically corresponding panels are horizontally slidably installed between the two side plates, and the panels are driven by corresponding translation components; and material blocking components are installed on both the left and right sides of the panels.

[0007] Preferably, the material blocking assembly includes a material blocking motor, a rotating shaft, and a baffle. The rotating shaft, which is powered by the material blocking motor, is mounted on the side of the panel, and the end of the baffle is fixed to the rotating shaft.

[0008] Preferably, a limiting block is horizontally fixed on the inner side of the side panel between the two panels.

[0009] Preferably, the first scraper assembly includes two vertically arranged first scrapers that are corresponding to each other on the left and right sides. The upper ends of the first scrapers are mounted on the corresponding first lifting assembly, and the first lifting assembly is mounted on the corresponding first transverse moving assembly.

[0010] Preferably, the second scraper assembly includes a vertically arranged second scraper, which is mounted on a second lifting assembly, which is mounted on a second transverse moving assembly.

[0011] Preferably, the feeding mechanism includes a feeding conveyor belt, on which a limiting component is installed. The limiting component includes a limiting plate and slide rails horizontally installed on both sides of the feeding conveyor belt. A slider slidably disposed on the slide rail is driven by a third transverse component, and the limiting plate is mounted on a third lifting component disposed on the slider.

[0012] Preferably, the drive assembly includes a fourth lifting assembly and a horizontal tilting assembly, the horizontal tilting assembly being mounted on the lifting frame of the fourth lifting assembly, and the suction cup being mounted on the actuating end of the horizontal tilting assembly.

[0013] Preferably, the horizontal flipping assembly includes a first motor, a second motor, and a first rotating rod and a second rotating rod arranged in parallel. One end of the first rotating rod is rotatably mounted on the lifting frame and is powered by the first motor. One end of the second rotating rod is rotatably mounted on the lifting frame, and a first rotating shaft is coaxially mounted at the rotation point. The first rotating shaft is powered by the second motor. A first sprocket is coaxially mounted on the first rotating shaft. The other end of the first rotating shaft, perpendicular to the two rotating rods, is provided with a second rotating shaft. The second rotating shaft is rotatably connected to the two rotating rods. A second sprocket is coaxially mounted in the middle of the second rotating shaft, and a transmission chain is provided between the two sprockets. The suction nozzle of the suction cup is set downward and fixed to its end perpendicular to the second rotating shaft.

[0014] Accordingly, the method for unloading medicine bottles based on the aforementioned medicine bottle unloading device specifically includes the following steps:

[0015] 1) The feeding mechanism transports the tray containing medicine bottles to the position opposite to the flipping mechanism;

[0016] 2) The two panels of the flipping mechanism move to the discharge port of the feeding mechanism and open the corresponding material blocking components;

[0017] 3) The pallet is pushed between the two panels by the second scraper of the second scraper assembly, and the material stop assembly is closed;

[0018] 4) The two panels, along with the tray, are moved to the other side of the tilting frame. The tilting frame is then rotated 180 degrees by the rotary motor, so that the tray and medicine bottle are in an inverted state. The upper panel opens the corresponding material stop component, and the panel is slid open horizontally.

[0019] 5) After the pallet is removed by the pallet retrieval mechanism, the upper panel slides back to its original position, and the corresponding material stop component closes and resets.

[0020] 6) The rotary motor drives the flipping frame to rotate 180 degrees in the opposite direction, so that the medicine bottle is flipped into an upright position with the bottle mouth facing upward;

[0021] 7) Open the baffle assembly on the upper panel near the feeding mechanism and control the panel to slide open horizontally. The two first scrapers of the first scraper assembly will push the medicine bottle onto the feeding mechanism.

[0022] The beneficial effects of this invention are as follows:

[0023] 1. The rotary motor of this invention can drive the flipping frame to rotate 180 degrees forward and backward, thereby realizing the rapid flipping of the tray and medicine bottle, effectively completing the tray retrieval operation and the medicine bottle reset.

[0024] 2. Two vertically corresponding panels are horizontally slidably installed between the two side plates. Each panel is connected to a corresponding translation component to drive the two panels to move independently horizontally, thereby completing the movement to the right to receive materials from the feeding mechanism, the movement to the left to discharge materials to the feeding mechanism, and the independent opening of the panels to facilitate the removal of the tray by the tray retrieval mechanism.

[0025] 3. The rotating shaft is installed on the left and right sides of the panel along the front-back direction, and one end of the baffle is fixedly installed on the rotating shaft. The two baffles on the same side of the two panels form a group. When the rotating shaft is driven by the corresponding material-blocking motor, the two baffles on the same side can be rotated up and down, thereby sealing the openings on both sides of the flipping mechanism.

[0026] 4. A limiting block is horizontally fixed on the inner side of the side panel between the two panels. The limiting block can limit the pallet in the front and back direction to prevent the pallet from shaking back and forth during the flipping action and provide pallet flipping stability.

[0027] 5. The three transverse moving components of the first scraper assembly and the second scraper assembly are all mounted on the same frame. Each transverse moving component is driven by an independent drive structure, which makes it easier for the device to load and unload materials and improves the material conveying efficiency.

[0028] 6. The first motor drives the first rotating rod to rotate 180 degrees, which in turn drives the second rotating rod to rotate synchronously. The second motor drives the first rotating shaft to rotate in the opposite direction. The power is transmitted to the second rotating shaft through the sprocket and chain, so that when the suction cup installed on the second rotating shaft moves, it is always in a horizontal state with the suction nozzle facing downward. When the suction cup moves to the tray on the flipping mechanism, the suction nozzle grabs the bottom of the tray, and then the horizontal flipping component rotates in the opposite direction to reset it. The tray can be removed from the flipping mechanism. With the up and down movement of the fourth lifting component, the removed tray can be placed downward in the centralized storage area for efficient centralized processing of the tray.

[0029] 7. When the first scraper assembly delivers the medicine bottle onto the feeding conveyor belt, the first scraper on the left side immediately moves upward after reaching the limit plate, then drives the third lateral movement assembly to move to the left. The limit plate and the first scraper on the right side, blocking the medicine bottle from the left and right, move it to the set position. Afterwards, the first scraper assembly resets, the third lifting assembly moves the limit plate upward, and the third lateral movement assembly moves the third lifting assembly and the limit scraper to the right to reset, resulting in higher efficiency.

[0035] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of the invention.

[0036] like Figure 1-5 As shown, this invention proposes a medicine bottle unloading device, including a feeding mechanism 3, a feeding mechanism 2, a tilting mechanism 1, a discharging mechanism 4, and a tray-retrieving mechanism 5. The tilting mechanism 1 is correspondingly located between the discharge end of the feeding mechanism 3 and the inlet end of the discharging mechanism 4. The feeding mechanism 2 is horizontally installed above the feeding mechanism 3, the tilting mechanism 1, and the discharging mechanism 4. The tray-retrieving mechanism 5 is installed on one side of the tilting mechanism 1.

[0037] like Figure 2-3As shown, the flipping mechanism 1 includes a support 10, a flipping frame, and a rotary motor 15. The flipping frame is rotatably mounted on the support 10 at its center. The rotary motor 15 is poweredly connected to the rotation shaft of the flipping frame. The rotary motor 15 can drive the flipping frame to rotate 180 degrees forward and backward, thereby realizing the rapid flipping of the tray 6 and the medicine bottle, completing the tray retrieval operation and the medicine bottle reset. In this embodiment, the flipping frame includes two side plates 11 arranged correspondingly at the front and rear. The two side plates 11 are rotatably mounted on the support 10 at their center. The rotation shaft of one of the side plates 11 is poweredly connected to the rotary motor 15. Two vertically corresponding panels 12 are horizontally slidably mounted between the two side plates 11. Each panel 12 is connected to a corresponding translation component 121, which is used to drive the two panels 12 to move independently horizontally, thereby completing the receiving of materials from the feeding mechanism 3, the discharge of materials from the feeding mechanism 4, and the independent opening of the panels 12 to facilitate the removal of the tray 6 by the tray retrieval mechanism 5.

[0038] Specifically, the translation assembly 121 includes a slide rail 1212 horizontally mounted on the side plate and a rodless cylinder 1211. The front and rear sides of the panel 12 are horizontally slidably mounted on the slide rail 1212, and the slider of the rodless cylinder 1211 is fixedly connected to the panel 12. The horizontal length of the side plate 11 is not less than twice the length of the panel 12, thereby facilitating the horizontal sliding and translation of the two panels 12 between the two side plates 11.

[0039] Each panel 12 has a corresponding baffle assembly 13 installed on its left and right sides. In this embodiment, the baffle assembly 13 includes a baffle 132 and a rotating shaft 131 that is powered by a baffle motor. The rotating shaft 131 is installed on the left and right sides of the panel 12 in the front-back direction, and the end of the baffle 132 is fixedly installed on the rotating shaft 131. The two baffles 132 on the same side of the two panels 12 form a group. Under the rotation drive of the corresponding rotating shaft 131, the two baffles 132 on the same side can be driven to flip up and down, thereby realizing the opening and closing of the openings on both sides of the flipping mechanism 1.

[0040] A limiting block 14 is horizontally fixed on the inner side of the side plate 11 between the two panels 12. The limiting block 14 can limit the tray 6 in the front and back direction to prevent the tray 6 from shaking back and forth during the flipping action and provide stability for the flipping of the tray 6.

[0041] The upper and lower panels 12, front and rear side panels 11, and left and right baffles 132 of the flipping mechanism 1 form a storage cavity, which can effectively protect the tray 6 containing medicine bottles when the flipping mechanism 1 rotates. When the flipping mechanism 1 feeds, the two panels 12 move to the right side near the feeding mechanism 3, and the two baffles 132 on the right side of the baffle assembly 13 flip outward. After the tray 6 containing medicine bottles is fed into the storage cavity from the right side, the rotating shaft 131 drives the two baffles 132 to reset and close, thereby effectively sealing the tray 6 in the storage cavity. The panels 12 carrying the tray 6 move to the left side of the rotating frame. The rotating motor 15 drives the flipping frame to rotate 180 degrees clockwise. At this time, the two panels 12 are on the right side of the flipping mechanism 1 and the panels 12 are upside down, with the mouth of the medicine bottle facing down and the bottom of the tray 6 facing up. Then the baffle 132 on the right side of the upper panel 12 is flipped open, and the panel 12 opens horizontally to the left. After the tray 6 is taken out, the baffle 132 and the upper panel 12 are reset, and the flipping frame is rotated 180 degrees counterclockwise to reset, so that the medicine bottle is in an upright position with the bottle mouth facing upward.

[0042] The feeding mechanism 2 includes a first scraper assembly for pushing medicine bottles from the flipping mechanism 1 to the unloading mechanism 4, and a second scraper assembly for pushing the tray 6 containing medicine bottles from the loading mechanism 3 to the flipping mechanism 1. In this embodiment, the first scraper assembly includes two vertically arranged first scrapers 213, with the upper ends of the first scrapers 213 mounted on corresponding first lifting components 212, and the first lifting components 212 mounted on corresponding first transverse components 211. The second scraper assembly includes a vertically arranged second scraper 223, which is mounted on a second lifting component 222, and the second lifting component 222 is mounted on a second transverse component 221.

[0043] In practice, all three transverse components are mounted on the same frame 20. Each transverse component is driven by an independent drive mechanism. The transverse components can adopt a structure in which a motor drives a chain to move the frame on the frame 20 horizontally. The three lifting components can adopt a telescopic cylinder structure, with the scraper vertically mounted on the piston rod below the telescopic cylinder, which makes it easier for the device to load and unload materials and improves the material conveying efficiency.

[0044] In this invention, the feeding mechanism 3 is a feeding conveyor belt that feeds materials in the front and back direction. The discharge port of the feeding conveyor belt is located on the left side near the flipping mechanism 1. The second scraper 223 of the second scraper assembly first descends to the right side of the tray 6, and then moves to the left to push the tray 6 conveyed on the feeding mechanism 3 onto the flipping mechanism 1.

[0045] When the medicine bottle is being fed, the two first scrapers 213 of the first scraper assembly move downward first, blocking the left and right sides of the medicine bottle on the take-out tray 6. Then the two first scrapers 213 move synchronously, pushing the medicine bottle to the left and into the feeding mechanism 4.

[0046] like Figure 4-5 As shown, the tray-grabbing mechanism 5 is located on the right side in front of the flipping mechanism 1, and includes a drive assembly and a suction cup 54. The suction cup 54 for gripping the tray 6 is installed on the moving end of the drive assembly. The drive assembly includes a fourth lifting assembly 51 and a horizontal flipping assembly 53. The horizontal flipping assembly 53 is installed on the lifting frame 52 of the fourth lifting assembly 51, and the suction cup 54 is installed on the moving end of the horizontal flipping assembly 53. In this embodiment, the fourth lifting assembly 51 uses a motor-driven chain drive, and the chain drives the lifting frame 52 to slide up and down on the vertical frame.

[0047] The horizontal flipping assembly 53 includes a first motor 531, a second motor, and a first rotating rod 532 and a second rotating rod 534 arranged in parallel. One end of the first rotating rod 532 is rotatably mounted on the lifting frame 52 and is powered by the first motor 531. One end of the second rotating rod 534 is rotatably mounted on the lifting frame 52, and a first rotating shaft 537 is coaxially mounted at the rotation point. The first rotating shaft 537 is powered by the second motor (not shown in the figure), and a first sprocket 538 is coaxially mounted on the first rotating shaft 537. The other end of the first rotating rod is perpendicular to the two rotating rods and passes through a second rotating shaft 535. The second rotating shaft 535 is rotatably connected to the two rotating rods. A second sprocket 533 is coaxially mounted in the middle of the second rotating shaft 535, and a transmission chain 536 is provided between the two sprockets. The suction nozzle 541 of the suction cup 54 is set downward and fixed to its end perpendicular to the second rotating shaft 535.

[0048] The first motor 531 drives the first rotating rod 532 to rotate 180 degrees. The first rotating rod 532 drives the second rotating rod 534 to rotate synchronously. The second motor drives the first rotating shaft 537 to rotate in the opposite direction. The power is transmitted to the second rotating shaft 535 through the sprocket and transmission chain 536. This ensures that when the suction cup 54 mounted on the second rotating shaft 535 is activated, it is always in a horizontal state with the suction nozzle 541 facing downwards. When the suction cup 54 moves to the tray 6 on the flipping mechanism 1, the suction nozzle 541 grabs the bottom of the tray 6, and then the horizontal flipping component 53 rotates in the opposite direction to reset it, thus removing the tray 6 from the flipping mechanism 1. With the up and down movement of the fourth lifting component 51, the removed tray 6 can be placed downwards in the centralized storage area for efficient centralized processing of the tray 6.

[0049] The unloading mechanism 4 includes an unloading conveyor belt, on which a limiting component is installed. The limiting component includes a limiting plate 41 and slide rails horizontally installed on both sides of the unloading conveyor belt. A slider slidably mounted on the slide rails is driven by a third transverse component 42. The limiting plate 41 is mounted on a third lifting component 43 mounted on the slider. In this embodiment, the third transverse component 42 can be in the form of a cylinder or an electric chain driving a moving block, and the third lifting component 43 can be a vertically mounted cylinder structure.

[0050] When the first scraper assembly delivers the medicine bottle onto the feeding conveyor belt, the first scraper 213 on the left side moves upward immediately after reaching the limiting plate 41, and then drives the third lateral movement assembly 42 to move to the left. The limiting plate 41 and the first scraper 213 on the right side block the medicine bottle from the left and right as it moves to the set position. Afterwards, the first scraper assembly resets, the third lifting assembly 43 drives the limiting plate 41 to move upward, and the third lateral movement assembly 42 drives the third lifting assembly 43 and the limiting plate 41 to reset to the right.

[0051] Accordingly, based on the above-mentioned medicine bottle unloading device, the present invention also proposes a medicine bottle unloading method, which specifically includes the following steps:

[0052] 1) The feeding mechanism 3 transports the tray 6 containing medicine bottles to a position opposite to the flipping mechanism 1;

[0053] 2) The two panels 12 of the flipping mechanism 1 are moved to the discharge port of the feeding mechanism 3, and the two baffles 132 on the right side of the panel 12 are flipped open;

[0054] 3) One or more trays 6 are pushed between the two panels 12 by the second scraper 223 of the second scraper assembly, and the two baffles 132 on the right side are closed;

[0055] 4) The two panels 12, along with the tray 6, are moved to the left side of the flipping frame. Then, the rotary motor 15 drives the flipping frame to rotate 180 degrees clockwise, so that the tray 6 and the medicine bottle are in an inverted state. At this time, the two panels 12 are on the right side of the rotating frame. The baffle 132 on the right side of the upper panel 12 is flipped open, and the panel 12 is slid open horizontally to the left.

[0056] 5) The fourth lifting component 51 and the horizontal flipping component 53 of the tray retrieval mechanism 5 work together to pick up the tray 6 by suction cup 54, and then the upper panel 12 slides to the right to reset, and the baffle 132 flips and closes again.

[0057] 6) The rotary motor 15 drives the flipping frame to rotate 180 degrees in the opposite direction, so that the medicine bottle is flipped to an upright position with the bottle mouth facing upward;

[0058] 7) The baffle 132 on the left side of the upper panel 12 is flipped open. The panel 12 is slid open to the right, and the two first scrapers 213 of the first scraper assembly clamp the medicine bottle on the panel 12 one in front and one behind and push it to the left to the feeding mechanism 4.

[0059] 8) After the first scraper 213 on the left reaches the limiting plate 41, it immediately moves upward. The medicine bottle is blocked by the limiting plate 41 of the limiting component and the first scraper 213 on the right and moves to the left to the set position. Then the first scraper component and the limiting component are reset.
