Detailed Implementation
[0023] Example 1
[0024] like Figures 1-4As shown, this utility model proposes an automatic labeling device for wine bottles, including a base 1, a state adjustment mechanism, a mounting frame 7, label rollers 13, a correction component, and a clamping component. Two vertical plates 2 are arranged parallel to each other on the base 1, and a conveyor belt 3 is arranged between the two vertical plates 2. A positioning component for monitoring the position of the wine bottles is arranged between the two vertical plates 2. The positioning component includes an infrared through-beam grating A201 and a PLC controller, and also includes a central control unit, which is mounted on the base 1 and electrically connected to the PLC controller. The infrared through-beam grating A201 includes a light source emitter A and a light receiver A, which are respectively mounted on the corresponding vertical plates 2. The PLC controller is mounted on the base 1 and electrically connected to the infrared through-beam grating A201. The state adjustment mechanism is mounted on the base 1. The mechanism includes a CCD camera 5 and a rotating assembly 6. The rotating assembly 6 includes a three-axis robotic arm 61 and a two-grip manipulator 62. A bracket A4 is mounted on the base 1. The body of the CCD camera 5 is connected to the bracket A4, with the detection end of the CCD camera 5 pointing downwards and towards the conveyor belt 3. The body of the three-axis robotic arm 61 is connected to the base 1, and the output end of the three-axis robotic arm 61 is connected to the two-grip manipulator. Both the CCD camera 5 and the rotating assembly 6 are electrically connected to the PLC controller. The state adjustment mechanism operates in the following conditions: The system aims to straighten a tilted wine bottle. A mounting bracket 7 is mounted on a base 1. The mounting bracket 7 has a guide plate 71 and two air shafts 8. A unwinding roller 9 and a take-up roller 10 are fixed to the two air shafts 8, respectively. The mounting bracket 7 also has a drive assembly A11 for rotating one of the air shafts 8. The drive assembly A11 includes, but is not limited to, a motor A. A transmission shaft is mounted on the mounting bracket 7, and a gear A is coaxially mounted on the transmission shaft. A gear B is coaxially mounted on the air shaft 8 where the take-up roller 10 is located. Gear B meshes with gear A. The motor A is connected to the mounting bracket 7. The output end of motor A is connected to the drive shaft via coupling A. A bracket B12 is mounted on the mounting frame 7. The label roller 13 is rotatably mounted on bracket B12. A drive assembly B14 for driving the label roller 13 is mounted on bracket B12. Drive assembly B14 includes, but is not limited to, motor B. The body of motor B is connected to bracket B12, and the output end of motor B is connected to the mounting shaft of label roller 13 via coupling B. A paper passage is provided between label roller 13 and guide plate 71. A web-correcting assembly is mounted on bracket B12. The web-correcting assembly includes... The device includes a movable frame 15, guide rollers 16, friction rollers 17, and an infrared photoelectric grating B19. A central shaft is vertically mounted on the movable frame 15 and is rotatably connected to a support B12. The guide rollers 16 and 17 are rotatably mounted at both ends of the movable frame 15 and are parallel to each other. A drive assembly C18 for driving the movable frame 15 to rotate is mounted on the support B12. The drive assembly C18 includes, but is not limited to, a motor C. The motor C is connected to the support B12, and the output end of the motor C is connected to the central shaft through a coupling C.The infrared through-beam grating B19 includes a light source emitter B and a light receiver B, which are spaced apart on the bracket B12. The edge of the label tape passes between the light source emitter B and the light receiver B. The infrared through-beam grating B19 is electrically connected to the PLC controller. The correction component monitors the movement of the label tape during operation and automatically aligns and corrects any deviations in the label tape. The clamping component is located on the vertical plate 2 on the side opposite the label roller 13. The clamping component includes a fixing frame 20, a U-shaped plate 21, and a drive component D23. The frame 20 is connected to one of the vertical plates 2, and the vertical plate 2 is provided with a through hole. The fixed frame 20 is provided with a sliding groove, and a guide rail is provided on the inner wall of the sliding groove. The U-shaped plate 21 is placed in the sliding groove and is slidably connected to the guide rail. A set of positioning wheels 22 are respectively rotatably arranged on the two horizontal arms of the U-shaped plate 21. The driving component D23 includes, but is not limited to, a cylinder. The body of the cylinder is set on the fixed frame 20, and the output end of the cylinder is connected to the U-shaped plate 21. When the cylinder is working, it drives the U-shaped plate 21 away from or close to the label roller 13. When the clamping component is working, it cooperates with the label roller 13 to limit the position of the wine bottle.
[0025] In this embodiment, the label paper strip on the unwinding roller 9 is first guided around the guide roller 16 and friction roller 17 in sequence, passing through the gap of the infrared photoelectric grating B19, and then through the gap between the label roller 13 and the guide plate 71. The release paper is wound on the take-up roller 10. Due to the action of the guide plate 71, the front end of the label automatically lifts up and opens when passing through the guide plate 71. The wine bottle moves along the conveyor belt 3. When the wine bottle passes under the CCD camera 5, the image captured by the CCD camera 5 is fed back to the PLC controller and the central control host. If the central control host determines that the wine bottle is tilted after comparison, the central control host converts the image information into the state coordinate information of the wine bottle and feeds it back to the PLC controller. The PLC controller controls the three-axis robotic arm 61 to start and cooperate with the two-grip robotic arm 62 to pick up the wine bottle. After the corresponding action of the three-axis robotic arm 61, the wine bottle is flipped and righted and placed back on the conveyor belt 3. Then the wine bottle continues to move along the conveyor belt 3. As the bottle continues to move, the end of the label automatically adheres to the bottle. At this point, the cylinder is activated, pushing the U-shaped plate 21 to move and causing the two sets of positioning wheels 22 to work with the label roller 13 to clamp the bottle. Motor B is then activated, driving the label roller 13 to rotate, thus rotating the bottle. As the bottle rotates, it pulls on the label, causing it to automatically adhere to the bottle. The label is pressed firmly onto the bottle by the label roller 13 while the bottle is rotating. During the labeling process, motor A drives the take-up roller to wind up the release paper. After labeling is complete, the cylinder drives the U-shaped plate 21 to slide back to its original position, and the bottle continues to move. During the label conveying process, the infrared photoelectric grating B19 captures the edge position. If the edge shifts up or down, the correction component intervenes. Motor C drives the movable frame 15 to adaptively rotate at an appropriate angle. The change in friction between the friction wheel 17 and the guide wheel 16 forces the label tape to quickly correct itself and return to the set height, thus achieving label correction.
[0026] Example 2
[0027] The automatic labeling device for wine bottles proposed in this utility model, compared with Embodiment 1, includes multiple sets of infrared photoelectric grating A201. One set of infrared photoelectric grating A201 is installed directly below the CCD camera 5, another set of infrared photoelectric grating A201 is installed directly below the two-claw manipulator 62, and another set is installed on the side of the label roller 13 near the feeding end of the conveyor belt 3.
[0028] In this embodiment, when the wine bottle on the conveyor belt 3 moves directly below the CCD camera 5, the infrared photoelectric grating A201 at that position detects the wine bottle, and the CCD camera 5 is activated. When no wine bottle is detected, the CCD camera 5 is turned off to achieve energy saving. When the wine bottle that needs to be adjusted moves below the two-grip manipulator 62, the three-axis manipulator 61, in conjunction with the two-grip manipulator 62 and the wine bottle status information captured by the CCD camera 5, straightens the wine bottle. At the same time, when the wine bottle moves to the side of the label roller 13, the cylinder is activated and begins to work, pushing the wine bottle until it is in contact with both the label roller 13 and the positioning wheel 22.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
