[0042] Both the horizontal conveyor line and the vertical conveyor line include a belt conveying mechanism, which is an existing mechanism. A stopper is fixed on the belt of the horizontal conveyor line to limit the glass fiber yarn roll.

[0043] In this embodiment, the gripping mechanism includes a first movable plate 11, to which an electric cylinder 12 is fixedly mounted. The electric cylinder's telescopic rod extends downward through the first movable plate and is fixedly mounted on a mounting base 13. A wide air gripper 14 is fixedly mounted at the lower end of the mounting base. The wide air gripper comprises two air gripper fingers, which are fixedly connected to the gripper 4. The electric cylinder drives the mounting base to move vertically, which in turn moves the electric gripper. The wide air gripper drives the two air gripper fingers toward or away from each other, thereby moving the two grippers toward or away from each other, thereby clamping or releasing the fiberglass yarn roll.

[0044] In this embodiment, a plurality of linear bearings are fixedly mounted on the first movable plate, wherein a guide shaft 15 is slidably fitted in the linear bearings, and the lower end of the guide shaft is fixedly connected to the mounting seat.

The first slider is fixedly connected to the first moving plate, and a rack 22 is fixedly mounted on the frame, with the first gear meshing with the rack for transmission. The first servo motor drives the first gear to rotate via the first reducer, and the first gear meshes with the rack, driving the first slider to slide along the linear guide, thereby driving the first moving plate to move horizontally.

[0047] In this embodiment, the film wrapping mechanism includes a film wrapping mounting platform 23 fixedly mounted on the frame, the film wrapping mounting platform is provided with a film passing hole to facilitate the passage of the packaging film, and a cutting platform 24 is fixedly mounted on the film wrapping mounting platform. Two yarn roll drive assemblies are installed on the film wrapping mounting platform, and the yarn roll drive assemblies are located on both sides of the cutting platform;

[0048] The yarn roll drive assembly includes two film wrapping brackets 25 fixedly mounted on the film wrapping mounting platform, two film wrapping rollers 26 are mounted on the film wrapping brackets via bearings, a drive motor 27 is fixedly mounted on the film wrapping brackets, the output shaft of the drive motor passes through the film wrapping brackets and is fixed with a film wrapping driving wheel, one end of one of the film wrapping rollers passes through the film wrapping brackets and is fixed with a film wrapping driven wheel, and the film wrapping driving wheel and the film wrapping driven wheel are connected by a film wrapping belt;

[0049] Two film roll brackets 28 are fixedly installed on the film wrapping mounting platform. The film roll brackets are located on the outside of the film wrapping brackets. A rotating shaft is installed on the film roll brackets through bearings. The rotating shaft is fixedly connected to a rotating arm 29. The rotating arm is U-shaped and a film roll plate 30 is fixed on the rotating arm. A film roll motor 31 is fixed on the film roll bracket, and the output shaft of the film roll motor is fixedly connected to the rotating shaft.

[0050] The film wrapping mounting platform is also equipped with a tensioning bracket 32, on which two tensioning rollers 33 are rotatably mounted, and the tensioning rollers are arranged opposite to the film holes;

[0051] Two cutting brackets are fixed on the cutting table, and a transverse film pressing cylinder 34 is fixed on the cutting bracket. The telescopic rod of the transverse film pressing cylinder is fixed to a mounting bracket, and the mounting bracket is fixed to a longitudinal film pressing cylinder 35. The piston rod of the longitudinal film pressing cylinder is set downward and fixed to a pressure plate 38; a rodless cylinder 36 is fixed on one side of the cutting bracket, and a film cutting blade 37 is fixed to the movable body of the rodless cylinder;

[0052] The film unwinding mechanism includes a film unwinding mounting platform 39 fixedly mounted on the frame, the film unwinding mounting platform is located below the film wrapping mounting platform, two film unwinding brackets are fixed on the film unwinding mounting platform, a film unwinding roller is mounted on the film unwinding bracket, a film roll 40 is sleeved on the outer side of the film unwinding roller, a motor seat is fixedly mounted on the film unwinding mounting platform, a film unwinding motor 41 is fixedly mounted on the motor seat, a film unwinding active wheel 42 is fixed to the output shaft of the film unwinding motor, a film unwinding driven wheel 43 is fixed to the outer side of the film unwinding roller, and the film unwinding active wheel and the film unwinding driven wheel are connected by a film unwinding belt 44.

[0053] The yarn roll is placed on the yarn roll drive assembly on the side of the cutting table near the horizontal conveyor line. That is, the yarn roll is placed on two film wrapping rollers. The film roll motor drives the rotating arm to rotate, and then drives the film roll plate to rotate, wrapping one end of the packaging film onto the yarn roll. The drive motor drives the film roll through the film wrapping active pulley, film wrapping belt, and film wrapping driven pulley to rotate, thereby driving the yarn roll to rotate, so that the packaging film is wrapped around the yarn roll. The yarn roll is then grabbed by the grabbing mechanism and driven to the yarn roll drive assembly on the side near the vertical conveyor line. The transverse film pressing cylinder drives the longitudinal film pressing cylinder toward each other. The longitudinal film pressing cylinder drives the pressure plate downward to press the packaging film. The rodless cylinder then drives the film cutting blade to move and cut the packaging film. The yarn roll drive assembly on the side near the vertical conveyor line then drives the yarn roll to rotate, so that the packaging film is wrapped around the outside of the yarn roll, completing the film wrapping. The packaging film is tensioned by the setting of the tensioning roller, so that it is better wrapped on the yarn roll.

[0054] When unwinding the film, the unwinding motor drives the unwinding roller to rotate through the unwinding active wheel, the unwinding belt and the unwinding driven wheel, so that the film roll rotates and the packaging film is unwound. The packaging film passes through the film hole upward and is tensioned by the tensioning roller, and then reaches the film wrapping station.

[0055] In this embodiment, the flip mechanism includes a second movable plate 45, on which a longitudinal movable assembly 46 is installed. The longitudinal movable assembly is used to drive the vertical movable assembly 47 to move. The second movable plate is provided with a clearance hole opposite to the vertical movable assembly. The vertical movable assembly is used to drive the mounting frame 48 to move. A rotating seat 49 is rotatably installed at the lower end of the mounting frame. The mounting frame is hinged with a stretching cylinder 50 through a support. The piston rod of the stretching cylinder is rotatably connected to the rotating seat. The rotating seat is fixed with a mounting seat 51, and a tightening support is fixed on the mounting seat. Cylinder 52, a connecting plate is fixed to the protruding end of the tightening cylinder, the mounting seat is provided with a through hole opposite to the connecting plate, a tightening seat 53 is fixed to the connecting plate through the through hole, a tightening slider 54 is fixed to the tightening seat, a tightening slide rail 55 that can slide with the tightening slider is fixed to the mounting seat opposite to the tightening slider, a movable tightening shoe 56 is fixed to the tightening seat, a fixed tightening shoe 57 is fixed to the mounting seat opposite to the movable tightening shoe, a bottom film pressing cylinder 58 is fixed to the side of the fixed tightening shoe opposite to the movable tightening shoe, and a film pressing plate 59 is fixed to the protruding end of the bottom film pressing cylinder.

[0056] In this way, the longitudinal moving assembly drives the mounting frame to move longitudinally, the second moving structure drives the frame to move laterally, and the vertical moving assembly drives the frame to move vertically, thus achieving three-axis movement of the frame. The piston rod of the stretching cylinder extends, driving the rotating seat to rotate, which can transform the yarn roll from a vertical state to a horizontal state. During the connection process with the yarn roll, the tightening cylinder contracts, and the tightening slider moves along the tightening slide rail, driving the tightening seat to move, so that the movable tightening tile approaches the fixed tightening tile, facilitating the insertion of the movable tightening tile and the fixed tightening tile into the yarn roll. After insertion, the tightening cylinder extends, and the movable tightening tile moves away from the fixed tightening tile. The yarn roll is tightened by using the movable tightening tile and the fixed tightening tile, and then the yarn roll can be driven to move and rotate. After the bottom smoothing mechanism smoothes one side of the yarn roll, the yarn roll is placed on the vertical conveyor line, and the piston rod of the bottom film pressing cylinder extends, driving the film pressing plate to move, and the film pressing plate flattens the packaging film facing the center of the yarn roll, completing automatic film pressing. When wrapping the yarn roll, the film on one side is aligned with the roll, while the film on the other side extends beyond the roll. Therefore, the bottom needs to be smoothed to flatten the excess film. The film pressing plate is then driven by the film pressing cylinder at the bottom to flatten the excess film. The movable and fixed support pads constitute the support assembly. The longitudinal movement assembly can utilize an electric cylinder and a lead screw-nut structure, while the vertical movement assembly can utilize a lead screw-nut structure, with guide rails and sliders for guidance. Both the longitudinal and vertical movement assemblies are common existing mechanical structures and will not be described in detail.

[0057] In this embodiment, the second movable structure includes a second servo motor 60, the output shaft of which is connected to a second reducer, which is fixedly mounted on a second movable plate. The output shaft of the second reducer passes through the second movable plate and is fixedly mounted with a second gear 61. A second slider 62 is slidably engaged with the linear guide, which is fixedly connected to the second movable plate. The second gear meshes with the rack for transmission. The second servo motor drives the second gear to rotate via the second reducer. The second gear meshes with the rack, driving the second slider to slide along the linear guide, thereby driving the second movable plate to move horizontally.

[0058] In this embodiment, the bottom-smoothing mechanism includes a bottom-smoothing plate 63 fixedly mounted on a frame. Two vertical smoothing cylinders 64 are fixedly mounted on the bottom-smoothing plate vertically, and two horizontal smoothing cylinders 65 are fixedly mounted on the bottom-smoothing plate horizontally. Smoothing plates 66 are fixed to the protruding ends of each of the vertical and horizontal smoothing cylinders. The vertical smoothing cylinders drive the smoothing plate to smooth two sides of the packaging film, while the horizontal smoothing cylinders drive the smoothing plate to smooth the other two sides of the packaging film.

[0059] In this embodiment, the vertical smoothing cylinder and the horizontal smoothing cylinder are both provided with an extension stroke adjusting rod 67. By setting the extension stroke adjusting rod, the extension amount of the cylinder can be adjusted according to the diameter of the yarn roll.

[0060] The entire device is connected to the PLC control system.

[0061] principle:

[0062] The horizontal conveyor line transports horizontally placed yarn rolls. The grabbing mechanism moves down and grabs the yarn roll with its claws. The yarn roll is then driven by the first moving mechanism to move above the yarn roll drive assembly and placed on the yarn roll drive assembly. The film rolling plate flips to a certain angle, wrapping the packaging film that was cut last time onto the yarn roll. The yarn roll drive assembly starts, rotates for a specified time, and then stops. The set number of layers of packaging film is then wrapped onto the outer surface of the yarn roll. The grabbing mechanism then moves the yarn roll to the yarn roll drive assembly on the other side of the cutting table. The horizontal film pressing cylinder extends, and the longitudinal film pressing cylinder moves down to press the packaging film. The rodless cylinder starts, and the film cutting blade installed on it cuts the packaging film. The yarn roll rolling assembly starts, wrapping the excess packaging film after cutting onto the yarn roll again. At this time, the flipping mechanism moves to the specified position so that the center of the tightening assembly is opposite to the center of the horizontal yarn roll. Then the longitudinal moving assembly is started to send the tightening assembly into the yarn roll paper tube to a specified depth. The tightening cylinder is extended to lift the movable tightening tile, thereby lifting the yarn roll and leaving the yarn roll rolling assembly. Then the vertical moving assembly moves upward to align the center of the yarn roll with the center hole of the bottom smoothing plate. After that, the longitudinal moving assembly is started again to drive the yarn roll to move. First, the vertical smoothing cylinder in the vertical direction is extended, and then the horizontal smoothing cylinder in the horizontal direction is extended to smooth the packaging film exposed at the bottom of the yarn roll (both the vertical smoothing cylinder and the horizontal smoothing cylinder are provided with an extension stroke adjustment rod, and the cylinder extension amount can be adjusted according to the diameter of the yarn roll). After the yarn roll is smoothed, the second moving structure drives the yarn roll to move, the stretching cylinder retracts, and the yarn roll is flipped from a horizontal state to a vertical state. The longitudinal moving component is started, and the upright yarn roll is aligned with the middle of the vertical conveyor line. Then the vertical moving component is started, the tightening cylinder retracts, and the yarn roll is placed on the vertical conveyor line. Finally, the bottom film pressing cylinder extends to completely flatten the wrinkled packaging film near the bottom center of the yarn roll, the vertical moving component moves up, and the flipping mechanism returns to the initial position to wait for the next work.

[0063] Finally, it should be noted that various modifications and variations of the present invention may be made by those skilled in the art without departing from the spirit and scope of the present invention. Thus, the present invention is intended to include such modifications and variations as fall within the scope of the claims and their equivalents.
