Description

Technical Field

[0001] This invention belongs to the field of medicine bottle filling and processing equipment, and specifically relates to a medicine bottle printing and mounting device. Background Technology

[0002] After ampoules and similar medicine bottles are filled, product information such as production batch numbers and dates need to be affixed to the bottle. The bottles are then placed into trays for the subsequent packaging process. To ensure the quality of the printing, bottles with substandard printing must be promptly screened and removed. During the tray placement stage, issues such as missing or extra bottles may occur, requiring timely screening of trays with substandard packaging. Existing bottle printing and tray placement equipment is inefficient and unable to effectively screen bottles with substandard printing or trays, necessitating manual assistance for inspection, which is also inefficient. Summary of the Invention

The tray waste detection and rejection mechanism includes a second detection mechanism for detecting the tray loading status of the medicine bottle and a second rejection mechanism for rejecting incorrectly loaded trays. The second detection mechanism and the second rejection mechanism are sequentially positioned above the third conveyor along its conveying direction. The third conveyor is equipped with a bottle pressing mechanism above its tail end for pressing medicine bottles into the box tray.

[0006] Preferably, the feeding mechanism includes a feeding conveyor belt and a first feeding screw and a second feeding screw mounted on the first housing. The medicine bottle is placed upright on the feeding conveyor belt. The first feeding screw is horizontally mounted at the discharge port of the feeding conveyor belt. The second feeding screw is arranged side by side with the first feeding screw and corresponding to each other end to end. A vertical baffle is provided on one side of the discharge end of the first feeding screw. The medicine bottle is fed vertically from between the vertical baffle and the first feeding screw into the feed end of the second feeding screw. A first arc-shaped baffle is provided on the side of the second feeding screw away from the vertical baffle. The side of the first arc-shaped baffle near the second feeding screw has an arc surface that gradually turns from vertical to horizontal, which is used to lay the medicine bottle down from vertical to horizontal.

[0008] Preferably, the second conveyor is also equipped with a bottle-sorting mechanism and a third detection mechanism for detecting the height of the medicine bottle. The bottle-sorting mechanism and the third detection mechanism are arranged in front of the first detection mechanism along the conveying direction of the second conveyor.

One end of the baffle is fixed to the movable frame, and the other end mates with the photoelectric detection component mounted on the detection frame.

[0010] Preferably, the first waste removal mechanism includes a second conveying and transfer mechanism, a third feeding screw, and a third conduit. The second conveying and transfer mechanism includes a second conduit and a second guide plate. The power-driven second conduit is vertically rotated and installed above the second conveyor. Multiple second grooves are evenly spaced on the circumference of the second conduit. Second negative pressure suction holes connected to an external negative pressure air source are opened within the second grooves. The second guide plate is located on the side of the second conduit and has a second guiding arc surface that cooperates with the second conduit. The third feeding screw is located above the second conduit, and a second arc-shaped baffle is provided on the side of the third feeding screw. The two arc-shaped baffles have a second guide arc surface that gradually turns from horizontal to vertical near the third feeding screw, used to turn the medicine bottle from horizontal to vertical. The second flower plate cooperates with the medicine bottle on the second conveyor below. The discharge end above the feeding gap between the second flower plate and the second guide plate receives the feeding end of the feeding gap between the third feeding screw and the second arc-shaped baffle. The third flower plate, driven by a power source, is horizontally rotated and installed at the tail of the third feeding screw. The third guide plate is provided on the outer periphery of the third flower plate. The feeding port of the third guide plate is connected to the feeding gap discharge end of the third feeding screw and the second arc-shaped baffle. The discharge port of the third guide plate is connected to the storage tray.

[0011] Preferably, the feeding mechanism includes a box tray conveyor, which is horizontally installed below the second conveyor, and the discharge port below the tail of the second conveyor is correspondingly set with the box tray on the box tray conveyor.

[0012] Preferably, the second waste removal mechanism includes a fourth conveyor and a material feeding mechanism. The fourth conveyor is installed side by side on one side of the third conveyor. A material feeding port is provided between the fourth conveyor and the third conveyor. The material feeding mechanism includes a rotating belt, two rotating wheels and multiple paddles. The rotating wheels driven by the belt are installed on a bracket above the material feeding port. The bracket is installed above the fourth conveyor and the third conveyor.

[0014] Preferably, the third conveyor and the second waste removal mechanism are mounted on the frame in an adjustable manner, both vertically and horizontally; the first conveying and transfer mechanism and the first waste removal mechanism are also mounted on the frame in an adjustable manner.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. Under the conveying of the first conveying screw, the medicine bottle enters the conveying gap between the vertical baffle and the first conveying screw in a vertical state, and is fed into the feeding end of the second conveying screw from the conveying gap between the vertical baffle and the first conveying screw. The second conveying screw is provided with a first arc-shaped baffle on the side away from the vertical baffle. The side of the first arc-shaped baffle near the second conveying screw is provided with an arc surface that gradually turns from vertical to horizontal, so as to change the medicine bottle from a vertical state to a horizontal lying state, which makes it easier for the medicine bottle to be conveyed horizontally and stably on the first conveyor.

[0017] 2. Under the negative pressure suction of the first negative pressure suction hole, the medicine bottles from the first conveyor can be effectively adsorbed and grasped, making the transfer and conveying of the medicine bottles from the first conveyor to the second conveyor with a height difference more stable. After the medicine bottles on the conveyor have completed the printing operation, they enter the conveying gap between the first pattern plate and the first guide plate. The medicine bottles stuck in the first groove in the first pattern plate are adsorbed by negative pressure and, under the guidance of the first guide plate, fall smoothly onto the second conveyor, thus completing the smooth transfer and conveying of the medicine bottles between the first conveyor and the second conveyor with a height difference.

[0018] 3. When the first inspection agency detects that the medicine bottle with unqualified printing is conveyed to the second tray by the second conveyor, the negative pressure suction action of the second negative pressure suction hole on the second tray, combined with the rotation of the second tray, sends it into the material conveying gap between the second tray and the second guide plate, thereby completing the effective grabbing of the medicine bottle with printing problems.

[0019] 4. The second conduit feeds the printed medicine bottle horizontally into the feed end of the third feeding screw. As the third feeding screw rotates and is guided by the second arc-shaped baffle, the medicine bottle is gradually adjusted from a horizontal state to an upright state. Then, through the rotation of the third conduit, the medicine bottle is sent from the discharge port of the third guide plate to the storage tray for centralized storage.

[0020] 5. When the second inspection agency detects that the number of medicine bottles in the tray on the third conveyor is missing or excessive, the tray is conveyed to the feeding mechanism. The roller drives the rotating belt to rotate, and the feeding plate sends the tray through the feeding port to the fourth conveyor. The fourth conveyor then conveys the tray with the filling problem to the recycling and processing station for centralized processing.

[0021] 6. By rotating the first lead screw driven by the first motor, the vertical adjustment frame, the horizontal adjustment frame, and the corresponding mechanism can be adjusted up and down. By rotating the second lead screw driven by the second motor, the horizontal adjustment frame and the corresponding mechanism can be adjusted forward and backward in the horizontal direction. This allows the device to effectively adjust the corresponding transmission and transfer mechanisms according to the processing and use of different types of medicine bottles, making the device adaptable to the printing and packaging production of different types of medicine bottles. At the same time, the adjustment is more convenient and the use is more convenient. Attached Figure Description

[0031] 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.

[0032] like Figure 1-9 As shown, this invention proposes a medicine bottle printing and mounting device, including a transmission mechanism, a printing mechanism 32, and a waste detection and rejection mechanism mounted on a frame 1. The transmission mechanism includes a first conveyor 3 and a second conveyor 4 arranged horizontally, and the printing mechanism 32 is located above the first conveyor 3. The first conveyor 3 is a chain conveyor, and the medicine bottle is horizontally supported and placed between two adjacent chain links above the chain conveyor. The printing mechanism 32 can perform printing operations on the body of the medicine bottle on the chain conveyor.

[0033] The feeding end of the first conveyor 3 is connected to the feeding mechanism. The feeding mechanism includes a feeding conveyor belt 21 and a first feeding screw 22 and a second feeding screw 24 mounted on the first housing 20. The medicine bottles are placed upright on the feeding conveyor belt 21 and conveyed forward to the first feeding screw 22. The first feeding screw 22 is horizontally mounted at the discharge port of the feeding conveyor belt 21, perpendicular to the feeding direction of the feeding conveyor belt 21. The second feeding screw 24 is arranged side by side with the first feeding screw 22 and is positioned end to end. A vertical baffle 201 is provided on one side of the discharge end of the first feeding screw 22. The discharge end of the second feeding screw 24 is connected to the feeding end of the first conveyor 3 through the discharge port below the first housing 20. Under the conveying of the first conveying screw 22, the medicine bottle enters the conveying gap between the vertical baffle 201 and the first conveying screw 22 in a vertical state, and is fed into the feeding end of the second conveying screw 24 from the conveying gap between the vertical baffle 201 and the first conveying screw 22. The second conveying screw 24 is provided with a first arc-shaped baffle 23 on the side away from the vertical baffle 201. The side of the first arc-shaped baffle 23 near the second conveying screw 24 is provided with an inclined guiding arc surface that gradually turns from vertical to horizontal, so that the medicine bottle can be changed from a vertical state to a horizontal lying state, which makes it easier for the medicine bottle to be conveyed horizontally and stably on the first conveyor 3.

[0034] The first conveyor 3 is higher than the second conveyor 4. The discharge end of the first conveyor 3 is connected to the feed end of the second conveyor 4 through a first conveying and transfer mechanism. The second conveyor 4 also uses a chain conveyor. Specifically, the first conveying and transfer mechanism includes a first guide plate 33 and a first conduit 31. Multiple arc-shaped first grooves 311 are evenly spaced on the circumference of the first conduit 31. Each first groove 311 has a first negative pressure suction hole 3111 that communicates with an external negative pressure air source. Under the negative pressure suction of the first negative pressure suction hole 3111, the medicine bottles from the first conveyor 3 can be effectively adsorbed and grasped, making the transfer of the medicine bottles from the first conveyor 3 to the second conveyor 4, which has a height difference, more stable. The power-driven first conduit 31 is vertically rotated and installed at the tail of the first conveyor 3, above the feed end of the second conveyor 4. The rotation of the first disc 31 is coordinated with the conveying speed of the first conveyor 3, the second conveyor 4, the first conveying screw 22, and the second conveying screw 24 to achieve stable conveying of medicine bottles.

[0035] The first guide plate 33 is installed below the tail of the first conveyor 3. The first guide plate 33 has a first guiding arc surface that cooperates with the first pattern plate 31. The material feeding gap between the first pattern plate 31 and the first guide plate 33 receives the unloading end of the first conveyor 3 above and connects to the feeding end of the second conveyor below. After the medicine bottle on the conveyor completes the printing operation, the medicine bottle enters the material feeding gap between the first pattern plate 31 and the first guide plate 33. The medicine bottle stuck in the first groove 311 in the first pattern plate 31 is stably adsorbed by negative pressure. Under the guidance of the first guide plate 33, it falls smoothly onto the second conveyor 4, thus completing the smooth transfer and conveying of the medicine bottle between the first conveyor 3 and the second conveyor 4, which have a height difference.

[0036] The waste removal and rejection mechanism includes a medicine bottle waste removal and rejection mechanism and a box tray waste removal and rejection mechanism. The medicine bottle waste removal and rejection mechanism includes a first detection mechanism 43 for detecting the printing condition of medicine bottles and a first rejection and rejection mechanism 44 for rejecting waste medicine bottles. The first detection mechanism 43 and the first rejection and rejection mechanism 44 are arranged sequentially above the second conveyor 4 along the material conveying direction. The first detection mechanism 43 adopts an existing vision inspection device.

[0037] The second conveyor 4 is also equipped with a bottle-sorting mechanism 41 and a third detection mechanism 42 for detecting the height of medicine bottles. Along the conveying direction of the second conveyor 4, the bottle-sorting mechanism 41 and the third detection mechanism 42 are sequentially arranged in front of the first detection mechanism 43. Specifically, the third detection mechanism includes a detection frame 421, a slide rail 422, a top block 424, a detector, and a tension spring 425. The detection frame 421 is mounted on the frame 1, and the slide rail 422 is horizontally mounted on the detection frame 421. A movable frame 423 is horizontally slidably mounted on the slide rail 422. The movable frame 423 includes a first movable plate 4231, a second movable plate 4232, and a third movable plate 4233. The first movable plate 4231 has an L-shaped structure, and its vertical portion is horizontally slidably mounted. On the slide rail 422, the second moving plate 4232 is adjustablely mounted on the horizontal part of the first moving plate 4231, and the third moving plate 4233 is adjustablely mounted on the second moving plate 4232. The top block 424 is fixedly connected to the bottom of the third moving plate 4233. The bottom surface of the top block 424 is provided with an inclined surface that cooperates with the medicine bottle on the second conveyor 4. The two ends of the tension spring 425 are horizontally fixed to the moving frame 423 and the detection frame 421 respectively, and are used for resetting the moving frame 423 and the top block 424. The detector includes a photoelectric detection component 427 and a baffle 426. One end of the baffle 426 is fixedly connected to the first moving plate 4231, and the other end cooperates with the photoelectric detection component 427 mounted on the detection frame 421. When the medicine bottle is being normally conveyed on the second conveyor 4, it is positioned between two adjacent chain rods and its height is lower than the top block 424 above the second conveyor 4, allowing it to pass under the third detection mechanism 42. When problems such as bottle jumping occur, the height of the problematic medicine bottle will be higher than the bottom of the top block 424. As the second conveyor 4 moves forward, the problematic medicine bottle will move horizontally against the top block 424 through the inclined surface below the top block 424, thereby driving the moving frame 423 to move. This causes the baffle 426 on the moving frame 423 to disengage from the photoelectric detection component 427, thus detecting the abnormal height of the medicine bottle. The equipment stops in time to ensure that the medicine bottle can pass stably through the first waste kicking mechanism and operate effectively, thereby effectively preventing medicine bottle breakage accidents.

[0038] The bottle sorting mechanism 41 includes a bottle sorting positioning plate 411 horizontally arranged above the second conveyor 4 near the bottom of the medicine bottle. It is used to position and sort the medicine bottles conveyed on the second conveyor 4. The bottle sorting positioning plate 411 is adjustablely mounted on the frame 1 through a corresponding adjusting plate 412. The tail of the bottle sorting positioning plate 411 is tilted at a certain angle towards the middle of the second conveyor 4 along the feeding direction of the second conveyor 4. Under the guiding action of the tilted bottle sorting positioning plate 411, the medicine bottles on the second conveyor 4 can be effectively sorted and positioned, making them more neat. This makes the subsequent printing inspection of the medicine bottles more accurate and makes it easier for the medicine bottles to be effectively placed into trays and boxes.

[0039] The first waste removal mechanism 44 includes a second conveying and transfer mechanism, a third feeding screw 444, and a third conduit 446. The second conveying and transfer mechanism includes a second conduit 441 and a second guide plate 442. The power-driven second conduit 441 is vertically rotated and mounted above the second conveyor 4. Multiple arc-shaped second grooves 4410 are evenly spaced on the circumference of the second conduit 441. Each second groove 4410 contains a second negative pressure suction hole connected to an external negative pressure air source. The second guide plate 442 is located on the side of the second conduit 441 and has a second guiding arc surface that mates with the second conduit 441. The lower part of the second groove 4410 of the second conduit 441 mates with medicine bottles on the second conveyor 4. When the first inspection agency 43 detects a medicine bottle with defective printing and it is conveyed to the second platen 441 by the second conveyor 4, the negative pressure suction action of the second negative pressure suction hole on the second platen 441 is used in conjunction with the rotation of the second platen 441 to send it into the material conveying gap between the second platen 441 and the second guide plate 442, thereby completing the effective grabbing of the medicine bottle with printing problems.

[0040] The third feeding screw 444, installed in the second housing 443, is horizontally positioned above the second conduit 441. A second arc-shaped baffle 445 is provided on the side of the third feeding screw 444. The second arc-shaped baffle 445 has an inclined guide arc surface that gradually changes from horizontal to vertical near the third feeding screw 444, used to change the medicine bottle from a horizontal to an upright position. The discharge end above the feeding gap between the second conduit 441 and the second guide plate 442 receives the feeding end of the feeding gap between the third feeding screw 444 and the second arc-shaped baffle 445. The third conduit 446, driven by a power source, is horizontally rotatably installed at the tail of the third feeding screw 444. A third guide plate 447 is provided on the outer periphery of the third conduit 446. The feeding port on the third guide plate 447 is connected to the feeding gap discharge end of the third feeding screw 444 and the second arc-shaped baffle 445. The discharge port on the third guide plate 447 is connected to the storage tray 448. The second conduit 441 horizontally feeds the problematic printed medicine bottles into the feed end of the third feeding screw 444. As the third feeding screw 444 rotates and is guided by the second arc-shaped baffle 445, the medicine bottles are gradually adjusted from a horizontal to an upright position. Then, through the rotation and conveying of the third conduit 446, the medicine bottles are sent from the discharge port of the third guide plate 447 into the storage tray 448 for centralized storage. This device uses the second conveying mechanism, the third feeding screw 444, and the third conduit 446 to transfer the printed medicine bottles from a horizontal to a vertical position. The upright placement of the medicine bottles makes them easier to store and transfer later. Furthermore, the centralized storage of problematic printed medicine bottles in the storage tray 448 facilitates subsequent recycling and processing.

[0041] Below the discharge end of the second conveyor 4 is a tray-feeding mechanism 5. The discharge end of the tray-feeding mechanism 5 is connected to a third conveyor 61. The tray-feeding mechanism 5 includes a tray conveyor, which is horizontally installed below the second conveyor 4. The discharge port at the lower end of the second conveyor 4 corresponds to the tray on the tray conveyor. The trays are smoothly conveyed forward on the tray conveyor, and in conjunction with the orderly downward discharge from the discharge port of the second conveyor 4, the medicine bottles fall one by one into the tray slots, thus completing the efficient tray-feeding operation. In addition, the feeding mechanism 5 of this device is equipped with a feeding mechanism for actuating the box tray. The feeding mechanism can be a plurality of blocks fixed at equal intervals along the length of the box tray conveyor belt. The box tray is placed on the box tray conveyor between adjacent blocks, and the movement or pausing of the box tray conveyor belt and the blocks is controlled. In coordination with the second conveyor 4 and the first waste removal mechanism 44, the medicine bottle is fed into the tray or the box tray is stopped at one or more stations relative to the medicine bottle on the second conveyor 4, thereby realizing the function of missing support compensation.

[0042] Since the medicine bottles on the second conveyor 4 correspond one-to-one with the trays on the lower tray conveyor, when the first rejecting mechanism 44 removes the unqualified medicine bottles printed on the second conveyor 4, there will be missing bottles among the continuously conveyed medicine bottles on the second conveyor 4, which do not correspond to the trays on the lower tray. At this time, by controlling the action of the tray conveyor, the tray can be stopped at one or more stations, so that the trays on the tray and the medicine bottle conveyor can be effectively matched and filled.

[0043] The tray inspection and rejection mechanism includes a second inspection mechanism 71 for detecting the placement of medicine bottles and a second rejection mechanism 72 for rejecting incorrectly placed trays. The second inspection mechanism 71 and the second rejection mechanism 72 are sequentially arranged above the third conveyor 61 along its conveying direction. The second inspection mechanism 71 also employs a visual inspection device. The second rejection mechanism 72 includes a fourth conveyor 62 and a feeding mechanism. The fourth conveyor 62 is installed side-by-side on one side of the third conveyor 61, with a feeding port 60 between the fourth conveyor 62 and the third conveyor 61. The feeding mechanism includes a rotating belt 722, two rotating wheels 721, and multiple feeding plates 7221. The power-driven rotating wheels 721 are mounted on a support above the feeding port 60. The rotating belt 722 is mounted on the rotating wheels 721 perpendicular to the conveying direction of the third conveyor 61. The feeding plates 7221 are fixed at equal intervals on the rotating belt 722. The rotating belt 722 and the rotating wheels 721 can be constructed using a belt and pulley structure. Both the fourth conveyor 62 and the third conveyor 61 are belt conveyors. In addition, the distance between two adjacent levers 7221 is greater than the width of the tray, so that the trays with qualified filling can pass through the gap between the levers 7221 and be sent to the next process.

[0044] When the second detection mechanism 71 detects that the number of medicine bottles in the tray on the third conveyor 61 is missing or excessive, the tray is conveyed to the feeding mechanism. The rotating wheel 721 drives the rotating belt 722 to rotate, and the feeding plate 7221 sends the tray through the feeding port 60 to the fourth conveyor 62. The fourth conveyor 62 then conveys the tray with the filling problem to the recycling and processing station for centralized processing.

[0045] Above the tail end of the third conveyor 61 is a bottle pressing mechanism 8 for pressing medicine bottles into the tray slots. The bottle pressing mechanism 8 includes a bottle pressing roller, which is vertically rotatable and installed at a certain height above the third conveyor 61. The bottle pressing roller can press down and completely insert medicine bottles that are not fully placed in the tray slots, thereby ensuring the quality of the medicine bottles entering the tray.

[0046] The third conveyor 61 and the fourth conveyor 62 are mounted on the frame 1 in an adjustable manner up and down and forward and backward via the first adjustment mechanism. The second detection mechanism 71 and the second waste removal mechanism 72 can be adjusted and operated together with the third conveyor 61 and the fourth conveyor 62.

[0047] The first adjustment mechanism includes a vertical adjustment frame 91 and a horizontal adjustment frame 92. The vertical adjustment frame 91 is L-shaped and is slidably mounted on the frame 1. A first lead screw 93 connected to the first motor is vertically mounted on the frame 1. The vertical part of the vertical adjustment frame 91 is threaded onto the first lead screw 93. The corresponding mechanism is mounted on the horizontal adjustment frame 92. The bottom of the horizontal adjustment frame 92 is horizontally slidably mounted on the horizontal part of the vertical adjustment frame 91. A second lead screw 94 connected to the second motor is mounted on the horizontal part of the vertical adjustment frame 91 in the front-back direction. The horizontal adjustment frame 92 is threaded onto the second lead screw 94. The first motor drives the first lead screw 93 to rotate, which enables the vertical adjustment frame 91, the horizontal adjustment frame 92 and the corresponding mechanism to move up and down. The second motor drives the second lead screw 94 to rotate, which enables the horizontal adjustment frame 92 and the corresponding mechanism to move forward and backward in the horizontal direction. This allows the device to effectively adjust the corresponding transmission and transfer mechanisms according to the processing and use of different types of medicine bottles, making the device adaptable to the printing and packaging production of different types of medicine bottles. At the same time, the adjustment is more convenient and the use is more convenient.

[0048] The first conveying and transfer mechanism and the first waste removal mechanism 44 are vertically adjustable and mounted on the frame 1. In specific implementation, the first conveying and transfer mechanism and the first waste removal mechanism 44 are mounted on corresponding moving modules on the frame. The moving modules are slidably mounted on the frame 1. The frame 1 is also vertically mounted with electric screws corresponding to different moving modules. The moving modules are threaded onto the corresponding electric screws and control the rotation of the corresponding electric screws. Through the corresponding moving modules, the first conveying and transfer mechanism or the first waste removal mechanism 44 is adjusted vertically as a whole, making the installation and debugging of this device more convenient and adaptable to the processing of different types of medicine bottles.

[0049] When using this invention, the feeding conveyor belt 21 feeds the upright medicine bottles. Through the cooperation of the first feeding screw 22, the second feeding screw 24 and the first arc-shaped baffle 23, the medicine bottles are changed from an upright state to a horizontal state and sent to the first conveyor 3. After being printed by the printing mechanism 32, the medicine bottles are smoothly transported to the second conveyor 4 with a height difference by the first conveying and transfer mechanism. The medicine bottles transported on the second conveyor 4 will be inspected by the first detection mechanism 43 to check the printing status of the medicine bottles. For medicine bottles with unqualified printing, the second flower plate 441 will grab them and then guide the medicine bottles with printing problems from a horizontal state to an upright state through the third feeding screw 444 and the second arc-shaped baffle 445. The medicine bottles with printing problems will be sent to the receiving mechanism 5 for loading. After the trays containing medicine bottles are sent to the third conveyor 61, they will be inspected by the second inspection mechanism 71 to check whether there are too many or too few bottles. The trays that pass the inspection will be sent to the next process by the third conveyor 61, while the trays that fail the inspection will be sent to the fourth conveyor 62 by the action of the feeding mechanism 7221. The fourth conveyor 62 will send them to the recycling and processing station for centralized processing.
