DETAILED DESCRIPTION

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of use of the present invention.

[0022] like Figure 1-8 As shown, the present invention proposes a medicine bottle packaging production line, including a medicine bottle feeding mechanism, the medicine bottle feeding mechanism includes a feeding conveyor belt 1 for conveying medicine bottles upright forward, and the discharge end of the tail of the feeding conveyor belt 1 is connected to the medicine bottle arranging mechanism, which can feed the medicine bottles upright into the medicine bottle arranging mechanism. The medicine bottle arranging mechanism is used to distribute and convey the medicine bottles in rows. Specifically, the medicine bottle arranging mechanism includes a bottle sorting and feeding assembly 22, an intermediate conveyor belt 21 and a grid assembly 23, and the intermediate conveyor belt 21 is connected end to end with the feeding conveyor belt 1. The grid assembly 23 is installed above the intermediate conveyor belt 21, and the grid assembly 23 includes a plurality of partitions arranged in parallel and spaced apart along the length direction of the intermediate conveyor belt 21, and a feeding gap is formed between adjacent partitions, and the width of the feeding gap matches the diameter of the medicine bottles, so that the medicine bottles can pass through the feeding gap in rows.

[0023] The bottle-organizing feeding assembly 22 is installed at the feeding port of the grid assembly 23, and includes a bottle-organizing plate 221 and a reciprocating drive assembly 223. The bottle-organizing plate 221 is horizontally slidably installed above the feeding port of the grid assembly 23 perpendicular to the feeding direction of the intermediate conveyor belt 21. Specifically, a guide rail is horizontally installed on the intermediate conveyor belt 21, and the bottle-organizing plate 221 is horizontally slidably installed on the guide rail, thereby improving its stability during reciprocating movement. Two bottle-organizing shifting blocks are fixedly provided below the bottle-organizing plate 221, and the two bottle-organizing shifting blocks are arranged on both sides of the feeding port of the grid assembly 23. The reciprocating drive assembly 223 is connected to the bottle-organizing plate 221, and can drive the bottle-organizing plate 221 to reciprocate and vibrate perpendicular to the feeding direction of the intermediate conveyor belt 21. Among them, the reciprocating drive assembly 223 includes a motor 2231, a connecting block 2232 and a push rod 2234. The motor 2231 is vertically installed on one side of the intermediate conveyor belt 21. The connecting block 2232 is fixedly connected to the output shaft of the motor 2231. One end of the push rod 2234 is rotatably connected to the bottle sorting plate 221. The other end of the push rod 2234 is rotatably connected to the upper end of the rotating shaft 2233. The lower end of the rotating shaft 2233 is vertically fixedly connected to the connecting block 2232 and is eccentrically arranged relative to the output shaft of the motor 2231.

[0024] When the grid assembly 23 is feeding, the motor 2231 drives the connecting block 2232 to rotate, and the eccentrically arranged rotating shaft 2233 can horizontally push the bottle sorting plate 221 to vibrate back and forth laterally through the push rod 2234, and then the two bottle sorting blocks 222 under the bottle sorting plate 221 are used to move the medicine bottles at the feeding port of the grid assembly 23 back and forth laterally, so that the medicine bottles can enter the feeding gap of the grid assembly 23 more smoothly, avoiding bridging, aggregation, and blockage of the medicine bottles at the inlet of the grid assembly 23, causing problems such as broken bottles.

[0025] In addition, both sides of the inner wall of the middle conveyor belt 21 are provided with an eight-shaped material guiding slope 211 which is inclined from the side wall of the middle conveyor belt 21 to the feed port of the grid assembly 23. Under the guiding effect of the material guiding slope 211, the medicine bottles transported forward on the middle conveyor belt 21 can be transported to the feed port of the grid assembly 23, so that the medicine bottles can be introduced into the feeding gap in the grid assembly 23 more quickly and effectively, avoiding problems such as material accumulation.

[0026] The grouped bottle pushing mechanism 4 is used to transfer the medicine bottles in groups. The grouped bottle pushing mechanism 4 is arranged above the grid assembly 23 and the bottle passing plate 3. The bottle passing plate 3 is horizontally arranged between the middle conveyor belt 21 and the middle part of the unloading mechanism. Limiting plates 30 are arranged on both sides of the bottle passing plate 3 to effectively limit the conveyed medicine bottles from both sides. A bottle suction area 34 is arranged at the tail of the bottle passing plate 3. After the medicine bottles are transferred to the bottle suction area 34, they can be placed on the unloading mechanism through the bottle grabbing mechanism 7. The grouped bottle pushing mechanism 4 includes a first scraper 41, a second scraper 42 and a third scraper 43 which are arranged vertically and parallelly in sequence along the feeding direction. The three scrapers are arranged vertically perpendicular to the feeding gap and the lower ends thereof are provided with a material-diverting tooth that can be inserted into the partition gap. The upper ends of the three scrapers are respectively installed on the vertical action ends of the corresponding lifting components, and the lifting components are installed on the horizontal action ends of the corresponding transverse movement components, so that the three scrapers can realize independent horizontal transverse movement and vertical lifting and lowering actions. The first scraper 41 is used to block and separate the medicine bottles; the second scraper 42 and the third scraper 43 are used to clamp the medicine bottle group and transport it to the bottle suction area 34 at the rear end of the bottle passing plate 3.

[0027] Through the lifting and lateral movement of the three scrapers, the equipment can laterally separate the medicine bottles separated into rows in the grid assembly 23 into groups again, and effectively transport them to the bottle suction area 34 of the bottle passing plate 3, and place them in the upper box tray of the unloading mechanism by the bottle grabbing mechanism 7, thereby significantly improving the loading efficiency of the medicine bottles.

[0028] A first through hole 31 is vertically penetrated through the bottle passing plate 3 near the grille assembly 23, and a first baffle 311 is movably disposed in the first through hole 31, and the first baffle 311 is connected to the action end of a first vertical driving assembly 312 below the bottle passing plate 3. The first vertical driving assembly 312 can be a first cylinder.

[0029] The first cylinder drives the first baffle 311 to extend upward from the first through hole 31, so as to block and position the medicine bottle conveyance in the grid assembly 23, thereby ensuring the neatness of the grouping of the medicine bottles and improving the subsequent loading quality of the medicine bottles.

[0030] A second through hole 32 is provided on the bottle passing plate 3 in front of the bottle suction area 34 along the feeding direction, and a second baffle 321 is provided in the second through hole 32 to move up and down, and the second baffle 321 is connected to the action end of the second vertical driving component 322 below the bottle passing plate 3. The second vertical driving component 322 adopts a second cylinder. In specific implementation, after the first baffle 311 and the second baffle 321 are lowered and reset, the top surfaces of the first baffle 311 and the second baffle 321 are flush with the bottle passing plate 3, which can just block the first through hole 31 and the second through hole 32, and does not affect the horizontal movement of the medicine bottle at the two through holes.

[0031] After the second scraper 42 and the third scraper 43 clamp the grouped medicine bottles from the front and rear sides and transport them to the bottle suction area 34, the second cylinder can drive the second baffle 321 to penetrate the second perforation 32 and extend upward, thereby effectively positioning the medicine bottles in the bottle suction area 34 to prevent the grouped medicine bottles from dispersing and affecting subsequent loading.

[0032] In addition, a third through hole 33 is formed through the tail of the bottle suction area 34, a third baffle 331 is vertically provided in the third through hole 33, the third baffle 331 is horizontally movable along the feeding direction, and the third baffle 331 is connected to the action end of the horizontal driving component 332 under the bottle passing plate 3. The horizontal driving component 332 adopts a horizontal third cylinder.

[0033] After the second scraper 42 and the third scraper 43 in the group of medicine bottles are clamped and transported to the bottle suction area 34, the medicine bottles are again blocked by the second baffle 321 and the third baffle 331, so that the group of medicine bottles are arranged in regular rows and columns. The arrangement structure at this time is the same as the loading state in the box tray. After the bottle gripping suction cup 71 of the bottle gripping mechanism 7 adsorbs and fixes the group of medicine bottles on the bottle suction area 34, the third cylinder drives the third scraper 43 to move backward, loosens the clamping of the medicine bottles to unload the force, and avoids the second baffle 321 and the third baffle 331 clamping too tightly to cause damage to the medicine bottles when the bottle gripping mechanism 7 takes the bottles.

[0034] The unloading mechanism includes a horizontal unloading conveyor belt 6, and a plurality of positioning blocks 61 are fixedly arranged at equal intervals on the belt surface of the unloading conveyor belt 6. Two adjacent positioning blocks 61 are provided with positioning grooves for placing box trays. The positioning grooves can effectively clamp the box trays, and effectively prevent the box trays from shaking due to loading and capping, which affects the packaging quality. The head end of the unloading conveyor belt 6 is connected to the box tray supply mechanism 5. The box tray from the box tray supply mechanism 5 can be effectively clamped in the positioning groove between two adjacent positioning blocks 61 on the unloading conveyor belt 6, and the box tray is sent to the bottle grabbing mechanism 7 during the transmission of the unloading conveyor belt 6.

[0035] The tail of the bottle passing plate 3 and the middle of the unloading conveyor belt 6 are provided with a bottle grabbing mechanism 7, which is used to grab the grouped medicine bottles in the bottle suction area 34 and place them in the box tray in the middle of the unloading mechanism. In this embodiment, the bottle grabbing mechanism 7 adopts a desktop robot, and the robot arm of the desktop robot is equipped with a bottle grabbing suction cup 71, which is used to absorb and grab the bottle heads of the grouped medicine bottles; the bottle grabbing suction cup 71 adopts a sponge suction cup. The tail end of the unloading mechanism is provided with a box cover supply mechanism 9 and a cover grabbing mechanism 8, and the cover grabbing mechanism 8 adopts a desktop robot, and the robot arm of the desktop robot is equipped with a cover grabbing suction cup 81, which can also adopt a sponge suction cup structure.

[0036] The robot of the bottle grabbing mechanism 7 drives the bottle grabbing suction cup 71 to move, and can grab the bottle head of the medicine bottle on the bottle suction area 34 and place it stably in the box tray on the unloading conveyor. As the unloading conveyor belt 6 continues to transport, when it reaches the tail end of the unloading conveyor belt 6, the cover grabbing mechanism 8 grabs the box cover on the box cover supply mechanism 9 and buckles it on the box tray with the medicine bottle, completing the complete packaging operation of the medicine bottle. After that, the unloading conveyor belt 6 sends the packaged medicine bottle to the next process.

[0037] The specific working principle of the present invention is as follows: The upright medicine bottles are transported to the middle conveyor belt 21 by the feeding conveyor belt 1. When the medicine bottles are transported to the feeding end of the grid assembly 23, the reciprocating drive assembly 223 pushes the bottle sorting plate 221 and the two bottle sorting blocks 222 to vibrate laterally through the push rod 2234, so that the medicine bottles can enter the feeding gap of the grid assembly 23 more smoothly; the lifting assembly and the transverse movement assembly corresponding to the first scraper 41 are actuated, so that the first scraper 41 moves downward to the front end of the medicine bottle and continues to move forward with the medicine bottle, and the first cylinder drives the first baffle 311 to rise. When the first scraper 41 follows the medicine bottle to the first baffle 311, the first scraper 41 rises and resets; then, according to the number of medicine bottle groups, The first scraper 41 and the second scraper 42 are synchronously descended and inserted into the corresponding gaps between the medicine bottles arranged in the feeding gap. The first scraper 41 first blocks the subsequent medicine bottles, and the third scraper 43 moves downward to the front of the grouped medicine bottles, and resets downward on the first baffle 311. The second scraper 42 and the third scraper 43 clamp the grouped medicine bottles one after the other and move them forward to the bottle suction area 34. Then the second baffle 321 of the second scraper 42 and the third scraper 43 rises and resets; the second baffle 321 rises upward so that the grouped medicine bottles are confined between the second baffle 321 and the third baffle 331. At this time, the grouping operation of the medicine bottles is completed; the subsequent grouping operation of the medicine bottles can be repeated continuously.

[0038] When loading, after the bottle-grabbing suction cup 71 of the bottle-grabbing mechanism 7 adsorbs and fixes the grouped medicine bottles on the bottle-grabbing area 34, the third cylinder drives the third scraper 43 to move backward, loosens the clamping of the medicine bottles to unload the force, and then the medicine bottles are stably placed in the box tray in the middle of the unloading conveyor through the robotic action of the bottle-grabbing mechanism 7. When the loaded box tray reaches the tail end of the unloading conveyor belt 6, the cover-grabbing mechanism 8 grabs the box cover on the box cover supply mechanism 9 and buckles it on the box tray with the loaded medicine bottles, thereby completing the complete packaging operation of the medicine bottles.
