Description

Technical Field

[0001] This invention relates to the field of labeling machine technology, and specifically to a high-speed labeling machine for blister packs. Background Technology

[0002] Blister boxes are a type of packaging box, characterized by their ultra-thin thickness, ultra-light weight (less than 50g), and transparent appearance. They are widely used for packaging various fruits or foods. To easily display information about the contents of the blister box, labels are usually affixed to its outer surface. Currently, labeling machines are mainly used to affix labels to the outer surface of empty blister boxes. After labeling, the fruits or food are placed inside. However, traditional blister box labeling machines are inefficient and cannot meet the needs of large-scale labeling production. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies by providing a high-speed labeling machine for blister boxes. It can realize a high-speed automated labeling production process for blister boxes, including stacking and feeding, material handling and adjustment, conveying and transferring, automatic labeling, detection and rejection, and flipping and stacking, which can meet the needs of large-scale labeling production.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A high-speed labeling machine for blister boxes includes a frame, and a feeding mechanism, a picking mechanism, a labeling mechanism, a detection and rejection mechanism, and a flipping and stacking mechanism arranged sequentially on the frame. A transfer mechanism is provided below the picking mechanism, the labeling mechanism, and the detection and rejection mechanism.

[0006] The feeding mechanism has a first channel and a first conveyor belt. The first conveyor belt is used to transport the stacked blister boxes in the first channel to one side of the picking mechanism in an upright position.

[0007] The material handling mechanism has a sun gear, a first motor, a turntable, and multiple suction components. The sun gear is mounted on the frame, and the axis of the turntable is coaxial with the axis of the sun gear. The multiple suction components are distributed in a ring on the turntable. The suction components are connected to the sun gear through planetary gears. The first motor can drive the turntable to rotate so that the suction nozzles on the suction components can take out the blister packs in the first channel in an upright position and transfer the blister packs in a flat position to the transfer mechanism.

[0008] The transfer mechanism has a second channel and a second conveyor belt. The second conveyor belt is used to sequentially transfer the blister boxes lying flat in the second channel to the labeling mechanism, the detection and rejection mechanism and the flipping and stacking mechanism.

[0009] The labeling mechanism is used to affix labels to the blister packs in the second channel;

[0010] The detection and rejection mechanism has a detection camera and a removal component. The detection camera is used to detect whether the labeling of the blister packs in the second channel is qualified, and the removal component is used to remove the blister packs with unqualified labels from the second channel.

[0011] The flipping and stacking mechanism has an arc-shaped channel, a second motor, a rotating frame, a guide, and multiple material feeding components. The arc-shaped channel is connected to the second channel. The multiple material feeding components are distributed in a ring on the rotating frame. The guide is provided with a non-circular guide groove. The guide wheel on the material feeding component is movably disposed in the non-circular guide groove. The second motor can drive the rotating frame to rotate so that the material feeding plate on the material feeding component can push the flat blister boxes to flip upward along the arc-shaped channel and stack the blister boxes in an upright posture.

[0012] By sequentially arranging a feeding mechanism, a picking mechanism, a labeling mechanism, an inspection and rejection mechanism, and a flipping and stacking mechanism on the frame, and with a transfer mechanism located below the picking, labeling, and inspection and rejection mechanisms, the feeding mechanism transports blister boxes in an upright position to one side of the picking mechanism. The picking mechanism removes the upright blister boxes and transfers them to the transfer mechanism in a flat position. The transfer mechanism then sequentially transfers the flat blister boxes to the labeling, inspection and rejection, and flipping and stacking mechanisms. The labeling mechanism affixes labels to the blister boxes, the inspection and rejection mechanism removes blister boxes with unqualified labels, and the flipping and stacking mechanism flips the flat blister boxes upwards and stacks them in an upright position. This achieves a high-speed automated labeling production process, including blister box stacking, feeding, picking, adjustment, conveying, automatic labeling, inspection and rejection, and flipping and stacking. It can complete the labeling operation of more than 180 blister boxes per minute, which can meet the needs of large-scale labeling production.

[0013] As a preferred embodiment, a material distribution assembly is provided on both sides of the output end of the first channel. The material distribution assembly has a material distribution screw and a third motor. The external thread portion of the material distribution screw extends into the first channel. The third motor drives the material distribution screw to rotate so that the external thread portion of the material distribution screw is screwed into the space between two adjacent blister packs.

The first rotating shaft and the second rotating shaft are drively connected. The suction nozzle is disposed on the second rotating shaft. The axis of the first rotating shaft and the axis of the second rotating shaft are not coaxial. The axis of the first rotating shaft, the axis of the second rotating shaft, and the axis of the turntable are parallel.

[0015] As a preferred embodiment, the planetary gears are connected to the sun gear via an intermediate gear, the intermediate gear is rotatably connected to the turntable, and the intermediate gear and the planetary gears have the same number of teeth.

[0016] As a preferred embodiment, the first rotating shaft is provided with a first synchronous pulley, and the second rotating shaft is provided with a second synchronous pulley, and the first synchronous pulley and the second synchronous pulley are connected by a synchronous belt drive.

[0017] As a preferred embodiment, the labeling mechanism has an even number of labeling units arranged side by side along the conveying direction of the second channel. During operation, half of the labeling units work simultaneously, while the other half are in standby or stopped.

[0018] As a preferred embodiment, the feeding assembly is provided with a connecting rod and a swing arm. The connecting rod is rotatably connected to the rotating frame, the feeding plate is mounted on the connecting rod, the bottom of the arc-shaped channel has a first clearance groove for the movement of the feeding plate, one end of the swing arm is connected to the end of the connecting rod near the guide member, and the other end of the swing arm is rotatably connected to the guide wheel.

[0019] As a preferred embodiment, a first linear guide groove is connected between the second channel and the arc-shaped channel. The bottom of the first linear guide groove has a second clearance groove for the movement of the material feeding plate. A blowing pipe is provided on the side of the first linear guide groove near the material feeding direction of the blister box. The blowing pipe can blow the blister box output from the second channel into the first linear guide groove.

[0020] As a preferred embodiment, the output end of the arc-shaped channel is connected to a second linear guide groove, and the bottom of the second linear guide groove has a third clearance groove for the movement of the feeding piece.

[0021] As a preferred embodiment, the output end of the second linear guide channel is provided with a platform, and a material transfer component is provided on one side of the platform. The material transfer component can push the blister packs stacked in the second linear guide channel forward onto the platform.

[0022] Compared with existing technologies, this invention has significant advantages and beneficial effects. Specifically, by sequentially arranging a feeding mechanism, a picking mechanism, a labeling mechanism, a detection and rejection mechanism, and a flipping and stacking mechanism on a frame, and with a transfer mechanism located below the picking mechanism, labeling mechanism, and detection and rejection mechanism, the feeding mechanism transports the blister boxes in an upright position to one side of the picking mechanism. The picking mechanism removes the upright blister boxes and transfers them to the transfer mechanism in a flat position. The transfer mechanism then sequentially transfers the flat blister boxes to the transfer mechanism. The process involves transferring the blister packs to a labeling mechanism, an inspection and rejection mechanism, and a flipping and stacking mechanism. The labeling mechanism affixes labels to the blister packs, the inspection and rejection mechanism removes blister packs that fail to meet labeling standards, and the flipping and stacking mechanism flips the blister packs from their flat positions upwards and stacks them in an upright position. This achieves a high-speed automated labeling production process, including blister pack stacking and feeding, material handling and adjustment, conveying and transferring, automatic labeling, inspection and rejection, and flipping and stacking. It can complete the labeling of more than 180 blister packs per minute, which can meet the needs of large-scale labeling production.

Therefore, they should not be construed as limitations on this invention.

[0039] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0040] like Figure 1-12 As shown, the present invention discloses a high-speed labeling machine for blister boxes, including a frame 10, and a feeding mechanism 20, a picking mechanism 30, a labeling mechanism 40, a detection and rejection mechanism 50, and a flipping and stacking mechanism 60 arranged sequentially on the frame 10. A transfer mechanism 70 is provided below the picking mechanism 30, the labeling mechanism 40, and the detection and rejection mechanism 50.

[0041] The feeding mechanism 20 has a first channel 21 and a first conveyor belt 22. The first conveyor belt 22 is located below the first channel 21. The first conveyor belt 22 can also be located inside the first channel 21. The first conveyor belt 22 is used to transport the blister boxes 90 stacked in the first channel 21 to one side of the picking mechanism 30 in an upright posture. It should be noted that when the opening of the receiving groove (not shown) on the blister box 90 is open in the horizontal direction, the posture of the blister box 90 is defined as an upright posture.

[0042] The material handling mechanism 30 includes a sun gear 31, a first motor 32, a turntable 33, and multiple suction components 34. For example, there are four suction components 34. The sun gear 31 is mounted on the frame 10. The axis of the turntable 33 is coaxial with the axis of the sun gear 31 and is perpendicular to the conveying direction of the first conveying channel 21. The multiple suction components 34 are arranged in a ring on the turntable 33. The suction components 34 are connected to the sun gear 31 through planetary gears 35. The first motor 32 can drive the turntable 33 to rotate so that the suction nozzles 341 on the suction components 34 can take out the blister box 90 in the first channel 21 in an upright position and transfer the blister box 90 in a flat position to the transfer mechanism 70. It should be noted that when the opening of the receiving slot on the blister box 90 is open downwards, the posture of the blister box 90 is defined as a flat position.

[0043] The transfer mechanism 70 has a second channel 71 and a second conveyor belt 72. The second conveyor belt 72 is used to sequentially transfer the blister packs 90 lying flat in the second channel 71 to the labeling mechanism 40, the detection and rejection mechanism 50, and the flipping and stacking mechanism 60. The second conveyor belt 72 is located below the second channel 71, and the width of the second conveyor belt 72 is smaller than the width of the second channel 71. Several push rods 721 are provided at intervals on the periphery of the second conveyor belt 72. The bottom of the second channel 71 is provided with a clearance groove 712 for the push rods 721 to move. The second conveyor belt 72 can drive the push rods 721 to move, so that the push rods 721 push the blister packs 90 lying flat in the second channel 71 to sequentially transfer to the labeling mechanism 40, the detection and rejection mechanism 50, and the flipping and stacking mechanism 60.

[0044] The labeling mechanism 401 is used to affix labels to the blister pack 90 in the second channel 71. The labeling mechanism 40 has multiple labeling units 41 arranged side-by-side along the conveying direction of the second channel 71. Each labeling unit 41 affixes a label to the blister pack 90 in the second channel 71. The labeling unit 41 is a mature existing technology, and its specific structure and principle will not be elaborated further. Specifically, the labeling mechanism 40 has an even number of labeling units 41 arranged side-by-side along the conveying direction of the second channel 71. During operation, half of the labeling units 41 work simultaneously, while the other half are on standby or stopped. By using an even number of labeling units 41, where half work simultaneously while the other half are on standby or stopped, it is convenient for workers to change the label rolls of the other half of the labeling units 41, achieving material change without stopping the equipment and resulting in high production efficiency.

[0045] The detection rejection mechanism 50 has a detection camera 51 and a removal component 52. The detection camera 51 is used to detect whether the labeling of the blister box 90 in the second channel 71 is qualified. The removal component 52 is used to remove the blister box 90 with unqualified labeling from the notch 711 on one side of the second channel 71. Specifically, the detection camera 51 is a high-speed camera, such as a CCD vision camera.

[0046] The flipping and stacking mechanism 60 has an arc-shaped channel 61, a second motor 62, a rotating frame 63, a guide 64, and multiple material-feeding components 65. For example, there are four material-feeding components 65. The arc-shaped channel 61 is connected to the second channel 71. The multiple material-feeding components 65 are arranged in a ring on the rotating frame 63. The guide 64 is mounted on the frame 10 and has a non-circular guide groove 641. The guide wheel 651 on the material-feeding component 65 is movably disposed in the non-circular guide groove 641. The second motor 62 can drive the rotating frame 63 to rotate so that the material-feeding piece 652 on the material-feeding component 65 can push the flat blister boxes 90 to flip upward along the arc-shaped channel 61 and stack the blister boxes 90 in an upright posture.

[0047] Both sides of the output end of the first channel 21 are provided with a dispensing assembly 23. The dispensing assembly 23 has a dispensing screw 24 and a third motor 25. The axis of the dispensing screw 24 is parallel to the conveying direction of the first channel 21. The external threads 241 on the periphery of the dispensing screw 24 extend into the first channel 21. The third motor 25 drives the dispensing screw 24 to rotate, so that the external threads 241 on the periphery of the dispensing screw 24 screw into the space between two adjacent blister packs 90. During operation, the dispensing screw 24 and... The first conveyor belt 22 operates synchronously, driving the blister boxes 90 forward. The material distribution screw 24 screws into two adjacent blister boxes 90 to separate them. By setting up a material distribution assembly 23 consisting of the material distribution screw 24 and the third motor 25, the external threads 241 on the material distribution screw 24 screw into two adjacent blister boxes 90 to separate them, preventing the two adjacent blister boxes 90 from sticking together and avoiding the material picking mechanism 30 from taking out blister boxes 90 that overlap.

[0048] The thickness d of the external thread 241 is 0.8mm-1.2mm, preferably 1mm. The height h of the external thread 241 is 4mm-6mm, preferably 5mm. The spacing s between two adjacent external threads 241 is 4mm-6mm, preferably 5mm. By using external threads 241 with a thickness d of 0.8mm-1.2mm and a height h of 4mm-6mm, and with a spacing s of 4mm-6mm between two adjacent external threads 241, the external thread 241 structure is thin and dense, resulting in more accurate material distribution for ultra-thin blister boxes 90, and better material distribution effect.

[0049] The material dispensing component 23 is adjustablely mounted on the frame 10 via a first adjusting component. The first adjusting component includes a first adjusting seat 26, a first screw 27, a second adjusting seat 28, and a second screw 29. The first adjusting seat 26 is slidably connected to the frame 10 vertically. The first screw 27 can adjust the first adjusting seat 26 vertically. Specifically, when the first screw 27 is mounted on the frame 10, it is threadedly connected to the first adjusting seat 26. Rotating the first screw 27 drives the first adjusting seat 26 to move vertically. The second adjusting seat 28 is slidably connected to the first adjusting seat 26 horizontally. The second screw 29 can adjust the second adjusting seat 28 horizontally. The material dispensing screw 24 and the third motor 25 are both mounted on the second adjusting seat 28. By setting the material dispensing component 23 to be adjustable vertically and horizontally, the fitting accuracy between the external thread 241 and the blister box 90 can be adjusted, improving the material dispensing efficiency. Furthermore, it is compatible with blister boxes 90 of different sizes, offering good versatility.

[0050] The second adjusting seat 28 is provided with a third adjusting seat 281 and a third screw 282. The third adjusting seat 281 is slidably connected to the second adjusting seat 28 in the left and right directions. The third screw 282 can adjust the third adjusting seat 281 in the left and right directions. The third adjusting seat 281 is provided with a fourth adjusting seat 283 and a fourth screw 284. The fourth adjusting seat 283 is slidably connected to the third adjusting seat 281 in the up and down directions. The fourth screw 284 can adjust the fourth adjusting seat 283 in the up and down directions. The fourth adjusting seat 283 is located at the... Above the channel 21, the fourth adjusting seat 283 can abut against the upper end of the blister box 90. The installation and adjustment methods of the second screw 29, the third screw 282, and the fourth screw 284 are the same as those of the first screw 27. By setting the fourth adjusting seat 283 to abut against the upper end of the blister box 90, in conjunction with the first conveyor belt 22 and the two material dispensing screws 24, the vertical and horizontal directions of the upright blister box 90 can be positioned, which is beneficial for the material picking mechanism 30 to take out the blister box 90.

[0051] Two parallel long plates 211 are provided above the first conveyor belt 22, and the first channel 21 is formed between the two long plates 211. Both long plates 211 can be adjusted left and right and installed on the frame 10 to adjust the width of the first channel 21.

[0052] The suction assembly 34 has a rotating base 342, a first rotating shaft 343, and a second rotating shaft 344. The first rotating shaft 343 is rotatably connected to the turntable 33. The planetary gear 35 is disposed on the first rotating shaft 343. The rotating base 342 is disposed on the first rotating shaft 343, and the second rotating shaft 344 is rotatably connected to the rotating base 342. The first rotating shaft 343 and the second rotating shaft 344 are drively connected. The suction nozzle 341 is disposed on the second rotating shaft 344. The axis of the first rotating shaft 343 and the axis of the second rotating shaft 344 are not coaxial. The axes of the first rotating shaft 343, the second rotating shaft 344, and the axis of the turntable 33 are parallel. By setting the rotating base 342, the first rotating shaft 343, and the second rotating shaft 344 on the suction assembly 34, and the first rotating shaft 343 and the second rotating shaft 344 are not coaxial, the suction assembly 34 adopts a dual-shaft structure. When the rotating seat 342 rotates, it also rotates around the first rotating axis 343, and the suction nozzle 341 rotates around the second rotating axis 344. By rotating the rotating seat 342 around the first rotating axis 343, the suction nozzle 341 can move radially independently relative to the turntable 33 and suck up the blister box 90 in a three-dimensional posture. By rotating the suction nozzle 341 around the second rotating axis 344, the suction nozzle 341 adjusts the sucked blister box 90 from a three-dimensional posture to a flat posture. By rotating the turntable 33, the suction nozzle 341 transfers the blister box 90 from the feeding mechanism 20 to the transfer mechanism 70, realizing high-speed automated material picking by the picking mechanism 30 and adjusting the posture of the blister box 90. It can complete the picking operation of more than 180 blister boxes 90 per minute. In addition, the radial independent extension and retraction of the suction nozzle 341 relative to the turntable 33 makes the suction nozzle 341 suitable for products of different heights, with good versatility.

[0053] The planetary gear 35 is connected to the sun gear 31 via an intermediate gear 36. The intermediate gear 36 is rotatably connected to the turntable 33. The intermediate gear 36 and the planetary gear 35 have the same number of teeth, and the ratio of the number of teeth of the planetary gear 35 to the sun gear 31 is 1:4.

[0054] The first rotating shaft 343 is provided with a first synchronous pulley 3431, and the second rotating shaft 344 is provided with a second synchronous pulley 3441. The first synchronous pulley 3431 and the second synchronous pulley 3441 are connected by a synchronous belt 345. The first synchronous pulley 3431 and the second synchronous pulley 3441 have the same number of teeth.

[0055] The turntable 33 is rotatably connected to the frame 10 via a third rotating shaft 37. The first motor 32 is driven by the third rotating shaft 37. The third rotating shaft 37 and the turntable 33 are provided with multiple independent first air passages, each air passage corresponding to a suction component 34. The rotating shaft is provided with a pneumatic slip ring 38 that communicates with the first air passage. The pneumatic slip ring 38 is connected to a negative pressure device. The pneumatic slip ring 38 is existing technology. The first rotating shaft 343 is provided with a second air passage. The first air passage is connected to the second air passage through a first air pipe (not shown). The second air passage is connected to the suction nozzle 341 through a second air pipe (not shown).

[0056] The removal component 52 is a first blowing tube, specifically a bamboo-joint air tube. One end of the first blowing tube is connected to a first air source, and the other end is connected to a blowing nozzle (not shown). The blowing nozzle faces the notch 711, and the blowing direction of the blowing nozzle is perpendicular to the conveying direction of the second channel 71. The blowing nozzle can directly blow out the unqualified blister boxes 90 in the second channel 71 through the notch 711. By setting the removal component 52 as a first blowing tube, the first blowing tube is equipped with a blowing nozzle facing the notch 711. The nozzle utilizes the ultra-thin and ultra-light characteristics of the blister box 90, allowing it to quickly blow out defective blister boxes 90 from the second channel 71 through the notch 711 in a very short time. This high efficiency does not affect the normal conveying of subsequent blister boxes 90, ensuring the overall operating efficiency of the labeling machine. The efficiency is even better when the blowing direction of the nozzle is perpendicular to the conveying direction of the second channel 71. In addition, the first blowing tube uses a bamboo joint air tube, which allows for free adjustment of the position and angle of the blowing nozzle, thereby achieving the best effect in removing defective products.

[0057] It should be noted that the ejector 52 can also be an impeller (not shown). The impeller is connected to a fourth motor (not shown). The axis of the impeller is parallel to the conveying direction of the second channel 71. Multiple blades (not shown) are distributed in a ring around the impeller. The fourth motor can be a servo motor. During operation, the fourth motor drives the impeller to rotate at a certain angle, so that the impeller drives the blades to rotate at a certain angle, and the blades push the unqualified blister box 90 out of the notch 711 of the second channel 71.

[0058] The feeding assembly 65 is provided with a connecting rod 653 and a swing arm 654. The connecting rod 653 is rotatably connected to the rotating frame 63. The feeding piece 652 is installed on the connecting rod 653. The bottom of the arc-shaped channel 61 has a first clearance groove 611 for the movement of the feeding piece 652. One end of the swing arm 654 is connected to the end of the connecting rod 653 near the guide member 64. The other end of the swing arm 654 is rotatably connected to the guide wheel 651. Specifically, there are two feeding pieces 652 arranged side by side on each feeding assembly 65.

[0059] The rotating frame 63 has two disks 631 arranged opposite to each other. The two disks 631 are connected together. The two ends of the connecting rod 653 are rotatably connected to the corresponding disks 631 respectively. The second motor 62 drives the two disks 631 to rotate synchronously.

[0060] A first linear guide groove 66 connects the second channel 71 and the arc-shaped channel 61. The bottom of the first linear guide groove 66 has a second clearance groove (not shown) for the movement of the material feeding piece 652. A second blowing pipe 73 is provided on the side of the first linear guide groove 66 near the material feeding direction of the blister box 90. The second blowing pipe 73 is connected to a second air source and is located above the second channel 71. The second blowing pipe 73 can blow the blister box 90 output from the second channel 71 into the first linear guide groove 66. Specifically, there are two second blowing pipes 73, which are second bamboo joint air pipes. By setting the second blowing pipes 73, the blister box 90 output from the second channel 71 is blown into the first linear guide groove 66, so that the blister box 90 can be quickly transferred from the second channel 71 to the first linear guide groove 66, thereby improving the conveying efficiency of the blister box 90.

[0061] The output end of the arc-shaped channel 61 is connected to a second linear guide groove 67. The bottom of the second linear guide groove 67 extends downward from front to back. The bottom of the second linear guide groove 67 has a third clearance groove (not shown) for the movement of the material pusher 652. The angle between the bottom of the second linear guide groove 67 and the horizontal plane is ≤5 degrees. By setting the bottom of the second linear guide groove 67 to extend upward along the conveying direction of the blister box 90, when the material pusher 652 pushes the blister box 90 to the second linear guide groove 67, the blister box 90 has a tendency to tilt and slide backward, so that the previous blister box 90 and the next blister box 90 are better stacked together, and the stacking effect is better. When the angle between the bottom of the second linear guide groove 67 and the horizontal plane is ≤5 degrees, it is beneficial for the material pusher 652 to push the stacked blister boxes 90 forward, making room for the subsequent blister boxes 90 to stack.

[0062] The output end of the second linear guide 67 is provided with a platform 80, and a material transfer component 68 is provided on one side of the platform 80. The material transfer component 68 can intermittently push the stacked blister boxes 90 in the second linear guide 67 forward onto the platform 80, and support the subsequent blister boxes 90 in the second linear guide 67 to prevent them from tipping forward. By setting up the platform 80 and the material transfer component 68, during material transfer, the material transfer component 68 intermittently pushes the stacked blister boxes 90 in the second linear guide 67 onto the platform 80, and supports the subsequent blister boxes 90 in the second linear guide 67 to prevent them from tipping forward, so that the subsequent blister boxes 90 are stacked smoothly.

[0063] The material transfer assembly 68 includes a material transfer base 681, a first drive unit 682, and a second drive unit 683. The material transfer base 681 is movably connected to the frame 10. The second drive unit 683 is disposed on the material transfer base 681. The drive end of the second drive unit 683 is connected to a material transfer rod 684 that can extend into or retract from the second linear guide groove 67. The first drive unit 682 drives the material transfer base 681 to move, so that the material transfer rod 684 intermittently pushes the stacked blister boxes 90 in the second linear guide groove 67 forward onto the platform 80, and supports the subsequent blister boxes 90 in the second linear guide groove 67 to prevent the blister boxes 90 from tipping forward. Specifically, the first drive unit 682 can adopt one of the following driving methods: linear motor, synchronous belt + stepper motor, or lead screw + stepper motor. The second drive unit 683 is disposed directly above the second linear guide groove 67, and the second drive unit 683 can be a cylinder.

[0064] A third conveyor belt 81 is provided on one side of the platform 80, and a third drive unit 82 is provided on the other side of the platform 80. The third drive unit 82 can push the blister boxes 90 stacked on the platform 80 to the third conveyor belt 81. Specifically, the third drive unit 82 can be a cylinder.

[0065] The flipping and stacking mechanism 60 also has a quantity detection component (not shown). When the quantity detection component detects that the blister boxes 90 in the second linear guide groove 67 have been stacked to the target quantity, the material transfer component 68 pushes the stacked blister boxes 90 in the second linear guide groove 67, whose quantity has been counted, forward onto the platform 80. The quantity detection component has a sensor. The sensor can count the number of stacked blister boxes 90 by detecting the number of rotations of the rotating frame 63, or by detecting the number of times the material transfer piece 652 moves the blister boxes 90. By setting the quantity detection component, the number of stacked blister boxes 90 can be counted without stopping the machine, and the material transfer component 68 can quickly push the stacked blister boxes 90, whose quantity has been counted, onto the platform 80, resulting in high automation efficiency.

[0066] Working principle of the invention:

[0067] Feeding: The worker places the stacked blister boxes 90 into the first channel 21. At this time, the blister boxes 90 are in an upright position. The first conveyor belt 22 transports the stacked blister boxes 90 in the first channel 21 forward. At the same time, the third motor 25 drives the distributing screw 24 to rotate, so that the external threads 241 on the periphery of the distributing screw 24 are screwed into the space between two adjacent blister boxes 90 to separate the two adjacent blister boxes 90.

[0068] Material handling: The first motor 32 drives the third shaft to rotate, the third shaft drives the turntable 33 to rotate, the turntable 33 drives the suction assembly 34 to rotate. During the rotation of the turntable 33, the planetary gear 35 and the intermediate gear 36 revolve around the sun gear 31, and the planetary gear 35 also rotates on its own axis, causing the planetary gear 35 to drive the first rotating shaft 343 to rotate. The first rotating shaft 343 drives the rotating seat 342, the rotating seat 342 drives the second rotating shaft 344 and the suction nozzle 341 to rotate. At the same time, the first rotating shaft 343 also drives the second rotating shaft 344 to rotate, causing the suction nozzle 341 to rotate around the first rotating shaft 343. The suction nozzle 341 picks up the blister box 90 in an upright position and adjusts the blister box 90 to a flat position and places it in the second conveying channel.

[0069] Transfer: The second conveyor belt 72 drives the pusher rod 721 to move, so that the pusher rod 721 pushes the blister boxes 90 lying flat in the second channel 71 to the labeling mechanism 40, the detection and rejection mechanism 50 and the flipping and stacking mechanism 60 in sequence. When the blister box 90 passes the labeling mechanism 40, the labeling unit 41 affixes the label to the blister box 90. When the blister box 90 passes the detection and rejection mechanism 50, the detection camera 51 detects whether the labeling of the blister box 90 is correct. The removal part 52 removes the blister box 90 with unqualified labeling from the notch 711 on one side of the second channel 71. The second blowing pipe 73 blows the blister box 90 with qualified labeling into the first linear guide groove 66.

[0070] Stacking: The second drive unit 683 drives the transfer rod 684 to extend downward into the second linear guide groove 67. The second motor 62 drives the rotating frame 63 to rotate. The rotating frame 63 drives the feeding assembly 65 to rotate. During the rotation of the rotating frame 63, the guide wheel 651 moves along the non-circular guide groove 641. The guide wheel 651 drives the swing arm 654 to rotate. The swing arm 654 drives the connecting rod 653 to rotate. The connecting rod 653 drives the feeding piece 652 to rotate. When the feeding piece 652 rotates to the first linear channel, the feeding piece 652 is in a horizontal state. When the feeding piece 652 rotates to the arc channel 61, the feeding piece 652 is in an inclined state. When the feeding piece 652 rotates to the second linear guide groove 67, the feeding piece 652 is in a vertical state. The feeding piece 652 pushes the blister box 90 in the first linear channel to pass through the arc channel 61 and the second linear guide groove 67 in sequence. The blister box 90 is adjusted from a flat position to an upright position. In the first position, the foremost blister box 90 abuts against the transfer rod 684, and the next blister box 90 is stacked with the previous one. During the stacking process, the first drive unit 682 drives the transfer seat 681 to move forward intermittently. The transfer seat 681 drives the second drive unit 683 and the transfer rod 684 to move forward intermittently in sync, so that the transfer rod 684 pushes the stacked blister boxes 90 onto the platform 80. When the quantity detection component detects that the blister boxes 90 in the second linear guide groove 67 have been stacked to the target quantity, the first drive unit 682 drives the transfer seat 681 to move forward quickly, so that the transfer rod 684 pushes the stacked blister boxes 90 that have been counted forward quickly onto the platform 80. Finally, the third drive unit 82 pushes the stacked blister boxes 90 on the platform 80 onto the third conveyor belt 81, and the third conveyor belt 81 transports the stacked blister boxes 90 to the next station.

[0071] In summary, this invention comprises a feeding mechanism 20, a picking mechanism 30, a labeling mechanism 40, a detection and rejection mechanism 50, and a flipping and stacking mechanism 60 sequentially arranged on a frame 10, and a transfer mechanism 70 located below the picking mechanism 30, labeling mechanism 40, and detection and rejection mechanism 50. The feeding mechanism 20 transports the blister box 90 in an upright position to one side of the picking mechanism 30. The picking mechanism 30 removes the upright blister box 90 and transfers it to the transfer mechanism 70 in a flat position. The transfer mechanism 70 then sequentially transfers the flat blister box 90 to the transfer mechanism 70. The system includes a labeling mechanism 40, an inspection and rejection mechanism 50, and a flipping and stacking mechanism 60. The labeling mechanism 40 affixes labels to blister boxes 90. The inspection and rejection mechanism 50 removes blister boxes 90 that fail to meet labeling standards. The flipping and stacking mechanism 60 flips the blister boxes 90 from their flat positions upwards and stacks them in an upright position. This achieves a high-speed automated labeling production process, including blister box 90 stacking, feeding, adjusting, conveying, automatic labeling, inspection and rejection, and flipping and stacking. It can complete the labeling operation of more than 180 blister boxes 90 per minute, which can meet the needs of large-scale labeling production.
