Description

Technical Field

[0001] The invention relates to a device for packaging ends of a coil, in particular to a device for automatically packaging paper caps at both ends of a coil and a packaging method. Background Art

[0002] During the winding and packaging process of the packaging film, the packaging film needs to be wound through a winding roller to form a roll of packaging film. After the winding is completed, both ends of the roll need to be wrapped with paper caps to protect the roll and prevent the roll from being damaged due to bumps during transportation or storage.

[0003] The packaging of paper caps on the ends of existing rolls is generally done manually. The worker attaches the paper cap to the end face of the end of the roll, at which time the paper cap partially protrudes from the edge of the end face of the roll. The worker presses the protruding part of the paper cap against the circumferential side wall of the end of the roll by hand, so that the paper cap is wrapped around the outside of the end of the roll. Then, the worker wraps the tape around the outside of the paper cap part wrapped on the circumferential side wall of the end of the roll, so that the paper cap is fixed on the end of the roll, completing the paper cap wrapping of the end of the roll.

[0004] Problems with manual wrapping: 1. Workers generally stack the paper caps on the workbench or on the lower ground. When placed on the workbench, the paper caps cannot be stacked higher while ensuring easy access, and workers need to frequently carry the paper caps to the workbench. When placed on the ground, although more paper caps can be stacked together, workers need to bend over to pick up the paper caps when taking them, which is labor-intensive and prone to fatigue after working for a long time; 2. It is difficult for workers to press the paper caps onto the end face of the roll while flattening them; 3. When the diameter of the roll is large, it is inconvenient for workers to flatten and wrap the tape; 4. Workers are prone to fatigue after long-term manual packaging operations, and cannot ensure high efficiency in the paper cap wrapping process. Summary of the Invention

[0018] Another topic: A packaging method for a device for automatically wrapping paper caps at both ends of a roll material, including a device for automatically wrapping paper caps at both ends of a roll material, comprising the following steps:

[0019] S1: First, the coil is placed on the conveyor device, the conveyor device conveys the coil forward, and the centering device centers the coil conveyed by the conveyor device to adjust the position of the coil;

[0020] S2: After the centering device centers the coil, the clamping device lifts the centered coil upwards and fixes the lifted coil;

[0021] S3: The loading pieces on both sides of the conveyor device are driven downward by the lifting driver 1 to lift the paper caps in the storage rack upward, and then the loading pieces are driven upward by the flip driver to flip the lifted paper caps from the horizontal state to the vertical state. At this time, the displacement drive mechanism 1 on both sides drives the loading pieces to move, so that the loading pieces on both sides press the paper caps in the vertical state onto the two end surfaces of the coil;

[0022] S4: The flattening devices on both sides respectively press on the paper caps at the two end surfaces of the coil in step S3, and the clamping and fixing device drives the coil to roll. The coil drives the paper caps pressed on the two end surfaces to rotate, so that the flattening devices on both sides flatten the paper caps at the ends of the coil onto a circle of the side wall of the coil;

[0023] S5: The tape winding devices on both sides stick the ends of the tape to the outside of the flattened paper cap at the end of the corresponding roll, and the tape is rotated by the paper cap and wound around the outside of the paper cap;

[0024] S6: After the tape is wound, the tape winding device cuts the tape and separates the tape portion wound around the outside of the paper cap, completing the paper cap wrapping of both ends of the roll.

[0025] Compared with the prior art, the present invention has the advantage that the storage space provided on the storage rack is used to stack paper caps. The storage space can store more paper caps for packaging, reducing the number of times of adding materials, and there is no problem of manual loading being affected by the height of the stacking materials.

[0026] When the end face of the coil is covered with a paper cap, the clamping and fixing device lifts the coil on the conveying device upward to fix the coil, and the loading piece is flipped to a vertical downward state opposite to the paper cap in the storage space. The lifting drive drives the unloading piece to move downward to lift the paper caps in the storage space one by one, and drives the flipping drive to flip upward so that the loading piece is flipped to a horizontal state. In this state, the loading piece is opposite to the lifted end face of the coil, and the displacement drive mechanism drives the loading piece to move to press the paper cap on the end face of the coil for packaging. The flattening device is used to press the paper cap pressed on the coil The paper cap on the end surface of the material is flattened on a circle of the circumferential side wall at the end of the coil. The tape winding device is used to wind the tape around the outside of the flattened paper cap, and cut the tape and separate it from the tape part wrapped around the outside of the paper cap to complete the paper cap wrapping on the end of the coil. Through the cooperation of the conveying device, the centering device, the clamping and fixing device, the feeding device, the flattening device and the tape winding device, mechanical automatic packaging is realized to maintain high packaging efficiency throughout the packaging process. Mechanical packaging can also effectively overcome the problem of difficulty in manual packaging due to the large diameter of the coil.

[0027] In addition, the paper cap is pressed onto the end face of the coil by the feeding piece, and the pressed paper cap is flattened by the flattening device, thereby avoiding the problem that the worker has difficulty in operating the paper cap while pressing it onto the end face of the coil. The equipment is equipped with matching feeding devices, flattening devices and tape winding devices on both sides of the conveying device to respectively cover the two ends of the lifted coil with paper caps, thereby completing the paper cap packaging of the two ends of the coil at the same time, and improving the packaging efficiency.

[0050] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only illustrative and exemplary and should not be construed as limiting the scope of protection of the invention.

[0051] It should be noted that like reference numerals denote like items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0052] Figures 1-20As shown, an automatic paper cap wrapping device for both ends of a roll material includes a frame 1, on which are provided a conveying device 2, a centering device 10, a feeding device, a flattening device 8, a controller 3, a clamping and fixing device 9 with a rolling drive, and a tape winding device 18 with an automatic cutting function.

[0053] The coil 16 is placed on the conveying device 2 , and the conveying device 2 can convey the placed coil 16 forward along the Y-axis direction.

[0054] Preferably, the conveying device 2 is a conveyor belt having limiter plates disposed along the conveyor belt surface. The coil 16 is placed transversely on the conveyor belt and positioned between two adjacent limiter plates. The limiter plates can restrict the coil 16 from rolling forward and backward on the conveyor belt. When the coil 16 is placed on the conveyor belt, the axis of the coil 16 is parallel to the X-axis.

[0055] A plurality of coils 16 are placed on the conveying device 2 in sequence from the back to the front, and are conveyed forward along the Y-axis direction by the conveying device 2 .

[0056] Figure 3 As shown, the centering device 10 is used to perform centering adjustment on the coil 16 placed on the conveying device 2 .

[0057] The centering device 10 includes two pulleys 14, a belt 1, two centering plates 15 and a push cylinder 11. The two pulleys 14 are fixed on the frame 1 and are spaced apart on the left and right sides in the X-axis direction. The two ends of the belt 1 are respectively connected to the two pulleys 14 to form an upper transmission belt 12 and a lower transmission belt 13. The movement directions of the upper transmission belt 12 and the lower transmission belt 13 are opposite. The two centering plates 15 are arranged on both sides of the conveying device 2, and the two centering plates 15 are respectively fixed on the upper transmission belt 12 and the lower transmission belt 13. When the belt 1 moves, it can drive the two centering plates 15 to clamp together or open to both sides at the same time. The piston rod of the push cylinder 11 is connected to the belt 1 and can drive the belt 1 to move. The piston rod of the push cylinder 11 telescopically moves in the X-axis direction.

[0058] When the piston rod of the push cylinder 11 is shortened, the belt drives the two pairs of center plates 15 to clamp together synchronously in the middle. The two pairs of center plates 15 clamp the two ends of the coil 16 in the process of moving toward the middle, and adjust the center of the coil 16 to prevent the coil 16 from deviating to one side when it is placed on the conveyor belt for transportation, so as to facilitate the subsequent packaging of the two ends of the coil 16 at the same time.

[0059] After the centering is completed, the piston rod of the push cylinder 11 is extended, and the belt drives the two centering plates 15 to move to both sides and open to stay away from the end face of the coil 16.

[0060] Preferably, the belt 1 is a toothed belt, the two pulleys 14 are gears for tensioning the belt 1, and the two pulleys 14 are engaged with the belt 1.

[0061] Figures 17-20 As shown, the clamping and fixing device 9 is arranged above the conveying device 2 and is located in front of the centering device 10. The clamping and fixing device 9 is used to lift the centered coil 16 upward to fix the coil 16, and can drive the lifted coil 16 to rotate around its own axis.

[0062] The clamping and fixing device 9 includes a mounting frame 83, a lifting driver 3 that drives the mounting frame 83 to move up and down in the Z-axis direction, two clamping jaws 85, an opening and closing driving mechanism that drives the two clamping jaws 85 to open and close the clamping, and a rotating driving mechanism 19 that drives the coil 16 to roll.

[0063] The lifting driver three is cylinder three 82. The cylinder body of cylinder three 82 is fixed on the frame 1. The end of the piston rod of cylinder three 82 is fixed to the mounting frame one 83. When the piston rod of cylinder three 82 is extended or retracted, it drives the mounting frame one 83 to move up and down in the Z-axis direction.

[0064] The two clamping jaws 85 are mounted on the mounting frame 1 83 and can slide relative to the mounting frame 1 83 in the Y-axis direction. The mounting frame 1 83 is rotatably connected to an intermediate connecting rod 93. Interconnecting rods 91 are hingedly connected at both ends of the intermediate connecting rod 93. The other ends of the two connecting rods 91 are respectively hingedly connected to the two clamping jaws 85, allowing the two clamping jaws 85 to simultaneously close toward the center and open to the sides. Preferably, a slide rail 1 92 is provided on the mounting frame 1 83, and the two clamping jaws 85 are slidably connected to the slide rail 1 92.

[0065] The opening and closing drive mechanism includes two cylinders four 84, and the two cylinders four 84 are fixed on the mounting frame one 83. The piston rods of the two cylinders four 84 are telescopically movable in the Y-axis direction, and the protruding ends of the piston rods of the two cylinders four 84 face opposite directions. The piston rods of the two cylinders four 84 are respectively connected to the two clamping jaws 85. When the piston rods of the two cylinders four 84 are extended or shortened at the same time, the two clamping jaws 85 are driven to move toward the middle to clamp or to move to the sides to open.

[0066] When the coil 16 needs to be grabbed, the piston rod of the cylinder three 82 drives the mounting frame 1 83 to move downward. At the same time, the two clamping jaws 85 are controlled by the opening and closing drive mechanism to open and close to clamp the coil 16 on the conveyor belt. Then the piston rod of the cylinder three 82 retracts to drive the mounting frame 1 83 to move upward to lift the clamped coil 16 upward.

[0067] In addition, a travel switch is provided directly below the clamping fixture 9. The travel switch, the clamping fixture 9, the conveying device 2, and the centering device 10 are all electrically connected to the controller 3. When the conveying device 2 conveys the centered coil 16 forward to the position directly below the clamping fixture 9, the travel switch detects the coil 16 and transmits a signal to the controller 3. The controller 3 controls the conveyor belt to stop, causing the centered coil 16 to stop directly below the clamping fixture 9. The two clamping jaws 85 move downward to clamp the coil 16 and lift it upward. The travel switch can be a sensor for sensing, such as a photoelectric sensor or a proximity sensor, or it can be a touch switch, such as a micro switch. When the coil 16 contacts the travel switch during conveyance, the travel switch is triggered.

[0068] The rotary drive mechanism 19 is used to drive the lifted coil 16 to rotate around its own axis.

[0069] Since the coil 16 to be clamped rotates relative to the clamping fixture 9, both clamping jaws 85 are provided with rolling wheels 86 as contact parts with the coil 16 when clamping the coil 16. When the rotary drive mechanism 19 drives the coil 16 to rotate, the rotation of the coil 16 drives the rolling wheels 86 to roll, reducing the friction between the coil 16 and the clamping jaws 85.

[0070] A rotation drive mechanism 19 is provided on one of the clamping jaws 85, and the rotation drive mechanism 19 includes a drive motor 90, a driving pulley 87 and a transmission pulley 89. The driving pulley 87 is connected to the output shaft of the drive motor 90 and is driven to rotate by the output shaft. The driving pulley 87 and the transmission pulley 89 are connected by a belt 2 88. When the two clamping jaws 85 clamp the aligned coil 16, the transmission pulley 89 contacts the clamped coil 16 and can drive the coil 16 to rotate relative to the two clamping jaws 85.

[0071] Both sides of the conveying device 2 are provided with a matching feeding device, a flattening device 8 and a tape winding device 18 for respectively wrapping the two ends of the lifted coil 16 with paper caps 5.

[0072] Figure 5-Figure 11 As shown, the feeding device includes a storage rack 4 for placing paper caps 5, a lifting mechanism 6 arranged corresponding to the storage rack 4, a loading mechanism 7 for conveying a single paper cap 5 in the storage rack 4 to a position where it contacts the end surface of the coil 16, and a displacement drive mechanism 1 for driving the loading mechanism 7 to move in the X-axis direction.

[0073] The storage rack 4 has a storage space 20 for stacking paper caps 5. The top of the storage space 20 has a material opening with an upward opening for placing or removing the paper caps 5. The paper caps 5 are stacked up and down in the storage space 20 in sequence. The paper caps 5 stacked in the storage space 20 are in a horizontal position.

[0074] Figure 8 As shown, preferably, the storage rack 4 includes a material platform 30 and a plurality of slides 31 arranged on the material platform 30, the material platform 30 is provided with a rotatable turntable 34, the turntable 34 is a circular turntable 34, and the plurality of slides 31 are arranged around the turntable 34 and can slide relative to the material platform 30 along the radial direction of the turntable 34, and a transmission connecting rod 33 is provided between the turntable 34 and each slide 31, one end of the transmission connecting rod 33 is hinged to the slide 31, and the other end of the transmission connecting rod 33 is hinged to the turntable 34 Eccentrically relative to the rotation center of the turntable 34, the drive connecting rod 33 drives each slide 31 to synchronously slide toward or away from the rotation center of the turntable 34 when the turntable 34 rotates forward or reverse. A locking member 38 is provided between the slide 31 and the material table 30 to lock the relative sliding. A vertically arranged limit frame 35 is fixed to each slide 31. Each limit frame 35 serves as the edge of the material storage space 20 to limit the horizontal deviation of the paper cap 5. Most preferably, four slides 31 are arranged around the outer side of the turntable 34, with each of the four slides 31 arranged opposite each other and sliding in the four directions of front, back, left, and right.

[0075] Specifically, the material table 30 is provided with a slide rail 2 37 corresponding to the slide 31, and the slide 31 is slidably set on the corresponding slide rail 2 37. The slide 31 is provided with a threaded hole passing through the upper and lower surfaces. The locking part 38 is a locking bolt threadedly connected to the threaded hole. Rotating the locking bolt can tighten the locking bolt against the material table 30, locking the relative sliding of the slide 31 and the material table 30.

[0076] When the paper caps 5 are placed in the storage space 20, the paper caps 5 can be placed in the storage space 20. For example, when a larger paper cap 5 is needed, the fastening bolt is rotated to move the fastening bolt upward and separate from the material platform 30. At this time, the slide 31 can slide relative to the material platform 30, and the turntable 34 is rotated counterclockwise to push the corresponding slides 31 outward through the transmission connecting rods 33, so that the slides 31 are away from the turntable 34, thereby increasing the distance between the two pairs of sliders and the paper caps 5.

[0077] A support block 32 is fixed on each slide 31, and a horizontal support plane is provided on the top of the support block 32 to serve as the bottom of the storage space 20. Preferably, the support block 32 is an inverted L-shaped block.

[0078] The lifting mechanism 6 is at least partially disposed below the bottom of the storage space 20 . The lifting mechanism 6 can lift the paper caps 5 in the storage space 20 and support the bottom of the paper caps 5 so that the paper caps 5 stacked on the top are at a set height.

[0079] Figure 5 、 Figure 7 As shown, preferably, the material lifting mechanism 6 is fixed on the material platform 30 of the corresponding material storage rack 4. The material lifting mechanism 6 includes a material lifting member 28 and a lifting driver 2 for driving the material lifting member 28 to move up and down in the Z-axis direction. The material lifting member 28 extends to the bottom of the material storage space 20 for lifting materials. There is a space between the support block 32 and the turntable 34 for the material lifting member 28 to be inserted. The material lifting member 28 is fork-shaped.

[0080] The lifting drive 2 includes a motor-screw module 1, which includes a motor 29, a fixed frame 23, a screw 1, a nut 1 and a sliding block 27. The fixed frame 23 is vertically fixed on the material table 30, and the sliding block 27 is connected to the fixed frame 23 and can slide up and down along the fixed frame 23 in the Z-axis direction. The motor 29 is fixed on the top of the fixed frame 23, the screw 1 is connected to the output shaft of the motor 29 and is driven to rotate by the screw 1, the nut 1 is threadedly connected to the screw 1, and the sliding block 27 is fixed on the nut 1. When the motor 29 drives the screw to rotate, it can drive the sliding block 27 to move up and down, thereby driving the lifting piece 28 to move up and down by the sliding block 27.

[0081] In addition, the storage rack 4 is provided with a sensor 36 for sensing the paper cap 5, and the sensor 36 is set at a set height. The fixed frame 23 is provided with an upper limit sensor 24 and a lower limit sensor 25. The upper limit sensor 24 and the lower limit sensor 25 are used to limit the highest rising position and the lowest descending position of the lifting member 28. The sliding block 27 has a sensing part 26 for the upper limit sensor 24 and the lower limit sensor 25 to sense. The sensor 36, the upper limit sensor 24, the lower limit sensor 25 and the lifting mechanism 6 are all electrically connected to the controller 3. When the feeding mechanism 7 grabs the paper cap 5 stacked on the top in the storage rack 4 and feeds it for packaging, the sensor 36 does not sense the presence of the paper cap 5 at the set height, and transmits an electrical signal to the controller 3. The controller 3 controls the lifting mechanism 6 to lift the material upward. When the sensor 36 senses the paper cap 5, the controller 3 controls the motor 29 to stop driving, so that the top paper cap 5 in the storage space 20 is always at the set height position for the feeding mechanism 7 to grab.

[0082] When the lifting piece 28 rises to the sensing part 26 and is sensed by the upper limit sensor 24, it indicates that all the paper caps 5 in the storage space 20 have been taken out. The upper limit sensor 24 transmits an electrical signal to the controller 3. The controller 3 controls the lifting driver 2 to drive the lifting piece 28 down, so that the lifting piece 28 descends to the position where the sensing part 26 is sensed by the lower limit sensor 25. At this time, the lifting piece 28 is below the bottom of the storage space 20, and the worker can add paper caps 5 to the storage space 20.

[0083] Preferably, sensor 1 36 is a photoelectric sensor, and the upper limit sensor 24 and the lower limit sensor 25 are proximity sensors.

[0084] In addition, both sides of the conveying device 2 are provided with a conversion platform 22 and a driving device 21 for driving the conversion platform 22 to rotate or translate. The conversion platform 22 is provided with multiple storage racks 4 for replacement and a lifting mechanism 6 arranged one-to-one corresponding to the storage racks 4. The rotation or translation of the conversion platform 22 causes the storage rack 4 to move to a position opposite to the loading mechanism 7 for feeding.

[0085] Figures 5-10 As shown, preferably, two storage racks 4 are installed on the conversion platform 22, and the two storage racks 4 are arranged in a line horizontally along the Y-axis direction. The driving device 21 drives the conversion platform 22 to move linearly in the Y-axis direction. The driving device 21 includes a rodless cylinder 42, a fixed frame 2 41 arranged on one side of the rodless cylinder 42, and a sliding block 2 46 arranged on the fixed frame 2 41. The fixed frame 2 41 is arranged along the Y-axis direction, and a slide rail 3 44 is provided on the fixed frame 2 41. The sliding block 2 46 is slidably connected to the slide rail 3 44, and the sliding block 2 46 can move along the slide rail 3 4 4 slides in the Y-axis direction relative to the second fixed frame 41. The above-mentioned conversion platform 22 is fixed on the second sliding block 46. The displacement block 43 of the rodless cylinder 42 is fixedly connected to the conversion platform 22. When the paper caps 5 in one of the two storage racks 4 are used up, the controller 3 controls the rodless cylinder 42 to drive the conversion platform 22 to move to one side, so that the other storage rack 4 containing paper caps 5 moves to the lower side opposite to the feeding mechanism 7 for feeding. During the feeding process, the worker can refill the used storage rack 4 to prepare for the next feeding.

[0086] Two limit blocks 45 are provided at the bottom of the conversion platform 22, and sensors 2 40 corresponding to the two limit blocks 45 are provided at both ends of the slide rail 3 44. When the right storage rack 4 needs to be fed, the rodless cylinder 42 drives the conversion platform 22 to move a fixed stroke to the left, and moves the right storage rack 4 to the bottom relative to the loading mechanism 7 for feeding. At this time, the left sensor 2 40 senses the limit block 45 on the left and transmits a signal to the controller 3. The controller 3 controls the loading mechanism 7 to start loading. When the left storage rack 4 needs to be fed, the rodless cylinder 42 drives the conversion platform 22 to move a fixed stroke to the right, and moves the left storage rack 4 to the bottom relative to the loading mechanism 7 for feeding. At this time, the right sensor 2 40 senses the limit block 45 on the right and transmits a signal to the controller 3. The controller 3 controls the loading mechanism 7 to start loading. The sensor 2 40 senses the limit block 45, indicating that the storage rack 4 has moved into place and can start loading.

[0087] In addition, buffers 39 are provided at both ends of the third slide rail 44. When the transfer platform 22 moves to one side by a fixed stroke, the stop block 45 contacts the buffer 39 on that side. The buffer 39 cushions the sliding movement of the second slide block 46, absorbing kinetic energy. The buffer 39 is a conventional hydraulic buffer structure, such as the Norman brand, model AC / AD hydraulic buffer.

[0088] Figure 11 As shown, the loading mechanism 7 includes a loading piece, a lifting drive 1 for driving the loading piece to move up and down in the Z-axis direction, and a flipping drive for driving the loading piece to flip. The flipping drive can drive the loading piece to flip up and down between a vertical downward state and a horizontal state. When the loading piece flips to the vertical downward state, the loading piece is opposite to the storage space 20 below. At this time, the lifting drive 1 can drive the loading piece to move downward, so that the lowering piece moves into the storage space 20 to grab the paper cap 5 stacked on the top, and then the lifting drive 1 drives the loading piece to move upward, lifts the grabbed single paper cap 5 to the discharge port, and when the loading piece flips to the horizontal state, the loading piece is opposite to the end face of the lifted coil 16. At this time, the displacement drive mechanism 1 drives the loading piece to move toward the end face of the coil 16, and the loading piece presses the lifted paper cap 5 on the end face of the coil 16 and is fixed relative to the coil 16. At this time, the paper cap 5 can be driven to rotate by the coil 16.

[0089] Preferably, the displacement drive mechanism 1 includes a motor-screw module 2, the motor-screw module 2 includes a fixed frame 3 47, a motor 2 48, a screw 2, a nut 2 and a sliding block 3 50, the fixed frame 3 47 is fixed on the frame 1, the motor 2 48 is fixed on the fixed frame 3 47, the screw 2 is connected to the output shaft of the motor 2 48 and is driven to rotate by the motor 2 48, the nut 2 is threadedly connected to the screw 2, the sliding block 3 50 is slidably connected to the fixed frame 3 47, the sliding block 3 50 is fixed to the nut 2, and when the motor 2 48 drives the screw 2 to rotate, it drives the sliding block 3 50 to move in the X-axis direction.

[0090] A mounting plate 1 78 is fixed on the sliding block 3 50 , and the above-mentioned feeding mechanism 7 is installed on the mounting plate 1 78 and can be driven by the mounting plate 1 78 to move in the X-axis direction.

[0091] Preferably, the lifting drive 1 includes a cylinder 1 51, the piston rod end of the cylinder 1 51 is fixedly connected to the mounting plate 2 52, the cylinder body of the cylinder 1 51 is fixed on the above-mentioned mounting plate 1 78, and the cylinder 1 51 can drive the mounting plate 2 52 to move up and down in the Z-axis direction. The flip drive includes a front fixing plate 56, a rear fixing plate 53 and a cylinder 2 55, the rear fixing plate 53 is fixedly connected to the mounting plate 2 52, and the front fixing plate 56 and the rear fixing plate 53 are connected by several The fixing rod 54 is connected and fixed, and the loading piece is rotatably connected to the front fixed plate 56. One end of the cylinder body of cylinder 2 55 is hinged to the rear fixed plate 53. The piston rod of cylinder 2 55 is hinged to the loading piece. A hinge shaft 1 58 is provided between the front fixed plate 56 and the loading piece. A hinge shaft 2 57 is provided between the piston rod of cylinder 2 55 and the loading piece. The hinge shaft 1 58 is parallel to the hinge shaft 2 57 and is not coaxial. When the piston rod of cylinder 2 55 is extended or retracted, it drives the loading piece to flip up and down.

[0092] When the piston rod of cylinder 2 55 is in an extended state, the grabbing piece is pushed by the piston rod to flip downward to a vertical downward state. When the piston rod of cylinder 2 55 is in a retracted state, the grabbing piece is pulled by the piston rod to flip upward to a horizontal state. The piston rod of cylinder 2 55 is extended and retracted to drive the grabbing piece 90 to flip, so that the grabbing piece can flip the grabbed paper cap 5 from a horizontal state to a vertical state.

[0093] Preferably, the loading part includes a fixing frame 4 59, a vacuum suction cup 61 for adsorbing the paper cap 5 and a rotating frame 60 for installing the vacuum suction cup 61. The fixing frame 4 59 is hinged to the cylinder 2 55 and the front fixing plate 56. The rotating frame 60 is rotatably connected to the fixing frame 4 59. When the material is flipped to a vertical downward state, the adsorption surface of the vacuum suction cup 61 faces downward to the paper cap 5 in the storage space 20. The cylinder 1 51 drives the vacuum suction cup 61 to move downward, so that the vacuum suction cup 61 touches the top paper cap 5 stacked in the storage space 20. The vacuum suction cup 61 adsorbs the paper cap 5, and then is driven upward by the cylinder 1 51 to move the vacuum suction cup 61 upward. The single paper cap 5 is driven upward to move out of the material outlet. At this time, the piston rod of the second cylinder 55 retracts, causing the material gripper to flip to a horizontal position. In this position, the suction surface of the vacuum suction cup 61 is horizontally oriented relative to the end face of the lifted web 16. The lifted paper cap 5 flips to a vertical position parallel to the end face of the web 16. The displacement drive mechanism 1 then drives the vacuum suction cup 61 to move in the X-axis direction, causing the vacuum suction cup 61 to press the sucked paper cap 5 against the end face of the web 16 and fix it to the web 16. At this time, because the rotating frame 60 can rotate relative to the fixed frame 4 59, when the web 16 rotates, the web 16 can drive the paper cap 5 pressed against the end face, as well as the vacuum suction cup 61 and the rotating frame 60 to rotate together. The rotating frame 60 is used to cooperate with the rotation of the web 16, so that the web 16 can drive the paper cap 5 to rotate.

[0094] In addition, a movable plate 63 is provided on the rotating frame 60, and the movable plate 63 can move forward and backward relative to the rotating frame 60. A support spring 65 is provided between the rotating frame 60 and the movable plate 63, and the support spring 65 pushes the movable plate 63 to move to the side away from the rotating frame 60. Preferably, a plurality of guide columns 64 are fixed on the surface of the rotating frame 60 for mounting the vacuum suction cup 61. The movable plate 63 is sleeved on the guide columns 64 and can move relative to the rotating frame 60 along the guide columns 64. A limiting bolt is fixed on the end of the guide column 64 away from the rotating frame 60. The limiting bolt limits the movable plate 63 from disengaging from the guide column 64, and the support spring 65 presses the movable plate 63 onto the limiting bolt. A through hole 62 is provided on the movable plate 63 for the vacuum suction cup 61 to pass through.

[0095] When the vacuum suction cup 61 moves to press the paper cap 5 onto the end face of the roll 16, the vacuum suction cup 61 is squeezed by the rotating frame 60 and the end face of the roll 16 and elastically compressed and deformed, shortening the distance between the rotating frame 60 and the end face of the roll 16, so that the movable plate 63 can touch and press on the paper cap 5. In this state, the movable plate 63 is pushed by the end face of the roll 16 to move slightly toward the side of the rotating frame 60, and the supporting spring 65 presses the movable plate 63 onto the paper cap 5, so that the paper cap 5 and the end face of the roll 16 are tightly fitted, preventing the paper cap 5 and the roll 16 from rotating relative to each other when the roll 16 rotates.

[0096] The third fixing frame 47 can be provided with a limit sensor 49 for limiting the travel of the third sliding block 50. The third sliding block 50 is provided with a second sensing portion for the limit sensor 49 to sense, thereby controlling the travel of the third sliding block 50 in driving the feeding mechanism 7 in the X-axis direction. Preferably, the limit sensor 49 can be a proximity sensor.

[0097] The flattening device 8 is used to flatten the paper cap 5 pressed on the end surface of the coil 16 onto a circle of the circumferential side wall of the end of the coil 16.

[0098] Figure 12-14 As shown, preferably, the flattening device 8 includes a flattening member and a translation drive mechanism, and the translation drive mechanism drives the flattening member to move in the X-axis direction so that the flattening member can move and switch between the initial position and the working position. When the flattening member moves to the working position relative to the circumferential side wall of the end of the coil 16, the flattening member contacts and presses on the paper cap 5 at the end of the coil 16, and the coil 16 drives the paper cap 5 to rotate so that the flattening member can flatten the paper cap 5 on a circle of side walls at the end of the coil 16.

[0099] Preferably, the translation drive mechanism includes a cylinder eight 79, and a fixed frame five 81 is fixed on the piston rod of the cylinder eight 79. The cylinder eight 79 can drive the fixed frame five 81 to move linearly in the X-axis direction. The above-mentioned flattening member is installed on the fixed frame five 81 and is driven to move by the fixed frame five 81, so that the flattening member moves and switches between the initial position and the working position.

[0100] Preferably, the flattening member includes a paper cap flattening roller 67, a guide limit plate 68 and an arc limit plate 69, which are respectively arranged on both sides of the paper cap flattening roller 67, and the guide limit plate 68 is arranged at an angle. When the flattening member moves to the working position, the guide limit plate 68 extends from one end of the paper cap flattening roller 67 to the side of the paper cap 5 away from the end face of the roll 16, which is used to feed the paper cap 5 into between the guide limit plate 68 and the roll 16, and the other end of the guide limit plate 68 extends to the outside of the circumferential side wall of the roll 16, and is adjacent to the contact pressure plane of the paper cap flattening roller 67 for flattening the paper cap 5, and the arc limit plate 69 is surrounded by the outside of the circumferential side wall of the roll 16, and there is a distance between the arc limit plate 69 and the circumferential side wall of the roll 16 for the paper cap 5 to rotate after being flattened by the paper cap flattening roller 67.

[0101] In addition, an end of the arc limiting plate 69 adjacent to the paper cap flattening roller 67 is provided with a flared opening to facilitate the flattened paper cap 5 to enter between the arc limiting plate 69 and the side wall of the coil 16.

[0102] When the flattening member moves to the working position, the flattening member first presses the edge of part of the paper cap 5 toward the side wall of the coil 16, and the coil 16 drives the paper cap 5 to rotate. The edge of one end of the paper cap 5 can be successively transferred between the guide limit plate 68 and the side wall of the coil 16. The paper cap 5 transferred under the guide limit plate 68 is gradually pressed down by the guide limit plate 68 and guided to the bottom of the contact pressure plane of the paper cap flattening roller 67. The paper cap flattening roller 67 presses on the paper cap 5 guided by the guide limit plate 68, and the paper cap is pressed. 5 is flattened on the side wall of the end of the coil 16. During this process, the paper cap flattening roller 67 rolls and presses on the paper cap 5. The roller, after being flattened by the paper cap 5, enters between the circular arc limit plate 69 and the side wall of the end of the coil 16 from the expanded opening of the circular arc limit plate 69. The circular arc limit plate 69 flattens it again to prevent the flattened paper cap 5 from tilting up. In the process of the coil 16 driving the paper cap 5 to rotate, the flattening member flattens the paper cap 5 on one side wall of the end of the coil 16 to wrap the end of the coil 16.

[0103] In addition, the flattening device 8 is connected to the displacement drive mechanism 1 and is driven by the displacement drive mechanism to move in the X-axis direction. When the displacement drive mechanism 1 drives the vacuum suction cup 61 to move and press the adsorbed paper cap 5 on the end surface of the coil 16, the flattening device 8 is in the initial position. At this position, there is still a gap between the flattening device 8 and the end of the coil 16. Specifically, the cylinder 8 79 is fixed on the mounting plate 1 78.

[0104] In addition, the flattening device 8 also includes a lifting drive four. Preferably, the lifting drive four includes a motor-screw module three 66. The motor-screw module three 66 is installed on the above-mentioned fixed frame five 81 and is driven to move by the fixed frame five 81. The above-mentioned flattening part is fixedly connected to the sliding block four of the motor-screw module three 66. The motor-screw module three 66 can drive the flattening part to move up and down in the Z-axis direction through the sliding block four to adjust the height of the flattening part to adapt to the flattening of coils 16 of different diameters.

[0105] The adhesive tape winding device 18 is used to wind the adhesive tape 76 around the outside of the flattened paper cap 5 and can cut the adhesive tape 76 and separate the part of the adhesive tape 76 wound around the outside of the paper cap 5.

[0106] The tape winding device 18 is arranged on one side of the arc limiting plate 69 to stick the tape 76 to the outer side of the flattened paper cap 5 that is rotated out from the bottom of the arc limiting plate 69.

[0107] Figure 12 、 Figure 16 As shown, preferably, the tape winding device 18 includes a clamping assembly, a second displacement driving mechanism for driving the clamping assembly to move in the X-axis direction, a third displacement driving mechanism for driving the clamping assembly to move in the Y-axis direction, and a cutting mechanism 17 for cutting the wound tape 76.

[0108] The second displacement drive mechanism includes a cylinder five 80 and a mounting frame two 72 fixed to the end of the piston rod of the cylinder five 80. The cylinder five 80 is used to drive the mounting frame two 72 to move in the X-axis direction. The third displacement drive mechanism includes a cylinder six 73 fixed on the mounting frame two 72 and a mounting frame three 74 fixed to the end of the piston rod of the cylinder six 73. The cylinder six 73 is used to drive the mounting frame three 74 to move in the Y-axis direction. A rotatable tape fixing wheel 77 is installed on the mounting frame two 72. The tape roll formed by winding the tape 76 is fixed on the tape fixing wheel 77. The clamping assembly includes a clamping wheel group 75 fixed on the mounting frame three 74. The end of the tape 76 is clamped between the clamping wheel group 75.

[0109] When it is necessary to wrap the flattened paper cap 5 with tape 76 and fix it, cylinder six 73 drives mounting bracket three 74 to move, and mounting bracket three 74 drives clamping wheel group 75 to move toward the side wall of coil 16 along the Y-axis direction, and clamping wheel group 75 drives the end of tape 76 to move and make the end of tape 76 adhere to the outer side of the paper cap 5 flattened at the end of coil 16. As coil 16 drives paper cap 5 to rotate, tape 76 adhered to the outer side of paper cap 5 can be wrapped around the outer side of flattened paper cap 5 in circles, fixing the flattened paper cap 5 to the outer side of the end of coil 16. In this process, the tape roll fixed on tape fixing wheel 77 is pulled and rotated.

[0110] The second displacement driving mechanism drives the clamping assembly to move in the X-axis direction so that the tape winding device 18 can realize reciprocating wrapping of paper caps 5 of different specifications with the tape 76 .

[0111] Preferably, the clamping wheel group 75 includes two clamping wheels rotatably mounted on the mounting frame 3 74. The two clamping wheels are arranged opposite to each other up and down, and there is a gap between the two clamping wheels for the end of the tape 76 to pass through. The two clamping wheels clamp on both sides of the passing tape 76.

[0112] The cutting mechanism 17 is used to cut the adhesive tape 76 and separate the portion of the adhesive tape 76 that is wrapped around the outside of the paper cap 5 .

[0113] Preferably, the cutting mechanism 17 is located below the clamping assembly. The cutting mechanism 17 includes a blade 71 and a displacement driver that drives the blade 71 to move obliquely upward and linearly. The displacement driver is installed on the second mounting frame 72. When the tape 76 is wound, the displacement driver drives the blade 71 to move obliquely upward to cut the tape 76 and separate it from the part of the tape 76 wrapped around the outside of the paper cap 5.

[0114] The displacement driver includes a cylinder 70 fixed on a mounting frame 2 72.

[0115] In addition, the above-mentioned cylinder five 80 is connected to the translation drive mechanism and is driven by the translation drive mechanism to move in the X-axis direction. The cylinder five 80 is fixed on the above-mentioned fixed frame five 81. When the translation drive mechanism drives the flattening member to move to the working position, the clamping wheel group 75 moves to a position opposite to the side wall of the end of the coil 16. The blade 71 faces the area between the clamping assembly and the coil 16. The clamping wheel group 75 drives the end of the tape 76 to move toward the coil 16 along the Y-axis direction, so that the end of the tape 76 contacts the flattened paper cap 5. The tape 76 is wrapped around the outside of the paper cap 5 during the rotation of the paper cap 5, and the blade 71 moves to cut the tape 76.

[0116] Through the cooperation of the conveying device 2, the centering device 10, the clamping and fixing device 9, the feeding device, the flattening device 8 and the tape winding device 18, mechanical automated packaging is achieved to maintain high packaging efficiency throughout the packaging process. Mechanical packaging can also effectively overcome the problem of difficulty in manual packaging due to the large diameter of the coil 16.

[0117] In addition, the paper cap 5 is pressed onto the end surface of the coil 16 by the feeding piece, and the pressed paper cap 5 is flattened by the flattening device 8, thereby avoiding the problem that the worker has difficulty in operating the paper cap 5 while pressing the paper cap 5 onto the end surface of the coil 16.
