[0018] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows: Example 1: Refer to Figure 1-17 As shown, the conveying device of an automatic roll forming machine in this embodiment includes a machine base 1, and a roll paper conveying unit, an outer roll paper conveying unit and a roll unit installed on the machine base 1. The roll paper conveying unit and the outer roll paper conveying unit are symmetrically installed on both sides of the upper end of the machine base 1, and the roll unit is installed at the end of the roll paper conveying unit and the outer roll paper conveying unit. The roll paper conveying unit includes a shelf 2, a first feeding trough 3, a second feeding trough 4, a third feeding trough 5, and a fourth feeding trough 6; a translational feeding robotic arm 7 is provided on the outside of the roll paper conveying unit. The translational feeding robotic arm 7 is used to gradually convey the roll paper from the first feeding trough 3 to the second feeding trough 4, the third feeding trough 5, and the fourth feeding trough 6. Three sets of fixed suction cups 71 are installed at equal intervals at the end of the translational feeding robotic arm 7.

[0019] The three sets of fixed suction cups 71 are used to move the roll paper on the first feeding groove 3 to the second feeding groove 4, move the roll paper on the second feeding groove 4 to the third feeding groove 5, and move the roll paper on the third feeding groove 5 to the fourth feeding groove 6, respectively, in a cycle to achieve the gradual feeding operation, and finally feed the roll paper to the roll unit for winding.

[0020] In some examples, the shelf 2 is fixedly installed on the upper surface of the machine base 1, and the first feeding trough 3 is movably installed at the bottom center of the shelf 2. The bottom of the first feeding trough 3 is provided with a first feeding pneumatic slide 31, which drives the first feeding trough 3 to perform horizontal sliding motion along the X-axis.

[0021] In some examples, a second feeding pneumatic slide 41 is provided at the bottom of the second feeding trough 4. The second feeding pneumatic slide 41 is used to drive the second feeding trough 4 to perform horizontal sliding motion along the Y-axis. A pressing and folding assembly is provided at the end of the second feeding trough 4. The pressing and folding assembly includes a pressing and folding die 42. A pressing and folding knife 43 is provided at the upper middle part of the pressing and folding die 42. A pressing and folding cylinder 44 is provided at the top of the pressing and folding knife 43. The pressing and folding knife 43 is driven to move up and down by the pressing and folding cylinder 44.

[0022] In some examples, the bottom of the fourth feeding trough 6 is provided with a rotary motor 61 and a fourth feeding pneumatic slide 62. The rotary motor 61 is used to drive the fourth feeding trough 6 to rotate, and the fourth feeding pneumatic slide 62 is used to drive the rotary motor 61 and the fourth feeding trough 6 to slide horizontally along the X-axis. In some examples, a glue-applying roller 63 is provided at the upper middle part of the fourth feeding trough 6, and a glue-applying cylinder 64 is provided at the top of the glue-applying roller 63. The specific working process of the roll paper conveying unit is as follows: The roll paper conveying unit includes a shelf 2, a first feeding trough 3, a second feeding trough 4, a third feeding trough 5, and a fourth feeding trough 6. The shelf 2 is fixedly installed on the upper surface of the machine base 1, and the roll paper is stacked inside. The first feeding trough 3 is movably installed at the bottom center of the shelf 2, and a first feeding pneumatic slide 31 is provided at its bottom.

[0023] During operation, the first feeding trough 3 moves to the bottom of the shelf 2. The rolls of paper stacked in the shelf 2 sink due to gravity, causing the bottom roll of paper to fall into the slot of the first feeding trough 3. Then the first feeding pneumatic slide 31 pushes out, driving the first feeding trough 3 and the roll of paper to move horizontally out along the X-axis.

[0024] Subsequently, the translational feeding robot arm 7 operates, and its end-mounted suction cup 71 adsorbs the roll paper and moves it into the second feeding trough 4. The bottom of the second feeding trough 4 is equipped with a second feeding pneumatic slide 41, which pushes the second feeding trough 4 to move horizontally along the Y-axis, so that the end of the roll paper extends into the folding die 42 in the folding assembly. At this time, the folding cylinder 44 pushes the folding knife 43 down to fold and bend the end of the roll paper. After the folding is completed, the second feeding pneumatic slide 41 resets. While the folding work is in progress, the first feeding trough 3 can repeat the above feeding action to prepare the next roll paper.

[0025] Subsequently, the rolled paper that has been folded is gradually conveyed by the horizontal feeding robot arm 7 to the third feeding trough 5 for temporary storage and transition, and then sent to the fourth feeding trough 6.

[0026] A rotary motor 61 and a fourth feeding pneumatic slide 62 are provided at the bottom of the fourth feeding trough 6. In front of the roll, the rotary motor 61 drives the fourth feeding trough 6 to rotate at a preset angle to adjust the orientation of the roll paper. Then, the fourth feeding pneumatic slide 62 pushes it to move along the X-axis to the roll roller 8. At the same time, the glue-applying cylinder 64 pushes the glue-applying roller 63 to descend and apply glue to the surface of the roll paper in preparation for winding.

[0027] Example 2: Refer to Figure 11-16 As shown, based on Embodiment 1, the conveying device of an automatic KONG machine further includes the following structure: The outer roll paper conveying unit includes a roll support frame 9, a conveyor belt 10, a first transfer platform 11, a second transfer platform 12, a third transfer platform 13, and a fourth transfer platform 14. A transfer robotic arm 15 is provided on the outside of the outer roll paper conveying unit. The transfer robotic arm 15 is used to gradually transfer the outer roll paper from the first transfer platform 11 to the second transfer platform 12, the third transfer platform 13, and the fourth transfer platform 14. The top of the transfer robotic arm 15 is provided with three sets of transfer suction cups 151 at equal intervals. Each transfer suction cup 151 is provided with a lifting cylinder 152 at its bottom. The lifting cylinder 152 is fixedly installed on the transfer robotic arm 15. An electric slide table 153 is provided at the bottom of the transfer robotic arm 15. The electric slide table 153 is used to drive the transfer robotic arm 15 to perform horizontal sliding motion along the X-axis. Limiting slide rails 154 are provided on both sides of the upper end of the electric slide table 153. The transfer robotic arm 15 is slidably installed on the two sets of limiting slide rails 154 by a slider. A push cylinder 155 is provided in the middle of the outer side of the transfer robotic arm 15. The push cylinder 155 is used to drive the transfer robotic arm 15 to perform horizontal sliding motion along the Y-axis.

[0028] The three sets of transfer suction cups 151 are used to move the outer tube paper on the first transfer table 11 to the second transfer table 12, move the outer tube paper on the second transfer table 12 to the third transfer table 13, and move the outer tube paper on the third transfer table 13 to the fourth transfer table 14, respectively, in a cycle to achieve the step-by-step transfer operation, and finally transfer the outer tube paper to the roll unit for winding.

[0029] The conveyor belt 10 is located at the bottom of the reel support frame 9, the first transfer table 11 is located at the outlet end of the conveyor belt 10, and a pneumatic shear 114 is provided between the first transfer table 11 and the conveyor belt 10. The bottom of the first transfer table 11 is provided with a first transfer pneumatic slide 111, which is used to drive the first transfer table 11 to perform horizontal sliding motion along the X-axis.

[0030] In some examples, a limiting cover plate 112 is movably installed at the upper middle part of the first transfer table 11, and a cover plate pneumatic slide 113 is provided at the bottom of the limiting cover plate 112. The cover plate pneumatic slide 113 is used to drive the limiting cover plate 112 to perform horizontal sliding motion along the Y axis.

[0031] In some examples, a cutter 131 is provided at the upper middle part of the third transfer table 13, an electric push rod 132 is provided at the top of the cutter 131, the electric push rod 132 is used to push the cutter 131 to move up and down, a waste guide plate 133 is provided on the back of the cutter 131, and a waste discharge chute 134 is provided at the bottom of the waste guide plate 133.

[0032] In some examples, the fourth transfer platform 14 is composed of multiple support plates 141, and a support cylinder 142 is provided at the bottom of the outermost support plate 141. The support cylinder 142 is used to push the corresponding support plate 141 to move up and down. A glue gun 16 is provided on one side of the upper end of the fourth transfer table 14, and the glue gun 16 is located on the outside of the roll unit.

[0033] In some examples, a drive assembly is provided on the side of the fourth transfer table 14. The drive assembly is used to drive the fourth transfer table 14 to perform horizontal sliding motion along the Y-axis. The drive assembly includes a ball screw 144, which is driven by a drive motor 145. The drive assembly also includes a support base 146, a ball screw 144 is movably mounted on the upper middle part of the support base 146, a sliding block 143 is drivenly connected to the ball screw 144, the sliding block 143 is fixedly mounted on the middle part of the base side of the fourth transfer table 14, and the two ends of the sliding block 143 are slidably connected to the limiting grooves on both sides of the support base 146 through limiting slide plates 147.

[0034] The specific working process of the outer tube paper conveying unit is as follows: In use, the outer paper roll is conveyed forward by the conveyor belt 10. During conveying, the limiting cover 112 is driven by the cover pneumatic slide 113 to cover the first transfer table 11. The outer paper roll passes through the reserved gap between the limiting cover 112 and the first transfer table 11, which serves as a limiting function. Then, the pneumatic scissors 114 cut the outer paper roll to the set length. After that, the limiting cover 112 is removed, and the first transfer pneumatic slide 111 drives the first transfer table 11 to move along the X-axis to the adsorption station of the transfer robotic arm 15.

[0035] The transfer robotic arm 15 has three sets of transfer suction cups 151 equidistantly arranged at the top, and an electric slide table 153 and a push cylinder 155 at the bottom. The transfer suction cups 151 move up and down to pick up the outer tube paper through the lifting cylinder 152, and under the coordinated drive of the electric slide table 153 and the push cylinder 155, the outer tube paper is gradually transported to the second transfer table 12, the third transfer table 13 and the fourth transfer table 14.

[0036] When the outer tube paper is on the third transfer table 13, the electric push rod 132 pushes the cutter 131 down to cut the rectangular outer tube paper into the required conical structure. The cut waste material falls into the waste discharge trough 134 through the waste guide plate 133 and is discharged. The cut outer tube paper is sent to the fourth transfer table 14.

[0037] The fourth transfer table 14 is composed of multiple support plates 141. The outermost support plate 141 has a support cylinder 142 at its bottom. When the outer roll paper is placed on the fourth transfer table 14, the drive assembly drives the fourth transfer table 14 to slide in the Y-axis direction. It first slides to the bottom of the glue gun 16. At this time, the glue gun 16 located outside the roll unit descends and sprays glue on the corresponding part of the outer surface of the outer roll paper. Then it resets. At this time, the drive motor 145 continues to drive the ball screw 144 to rotate. Through the sliding block 143, the fourth transfer table 14 is driven to move horizontally along the Y-axis to the roll 8. Then, the support cylinder 142 pushes the corresponding support plate 141 to rise, lifting the outer roll paper so that it contacts the roll 8.

[0038] Example 3: Reference Figure 1-17 As shown, based on Embodiments 1-2, the conveying device of an automatic KONG machine further includes the following structure: In this invention, the roll unit adopts a double roll 8 structure, a rotating arm 81 for driving the two sets of rolls 8 to rotate, and a servo motor 82 for driving the rotating arm 81 to rotate. In some examples, the upper middle part of the machine 1 is provided with a discharge assembly, including a discharge gripper 17 and a discharge cylinder 18 for pushing the discharge gripper 17 to move horizontally.

[0039] The working process of the drum unit and unloading is as follows: The roll unit includes two sets of conical rolls 8, a rotating arm 81, and a servo motor 82. In the initial state, one roll 8 first receives the roll paper that has been coated with glue. Then, the negative pressure suction hole on the roll 8 adsorbs the roll paper and starts to rotate to wind the roll paper into a core. After winding, the servo motor 82 drives the rotating arm 81 to rotate, so that the roll 8 with the roll paper rotates to the outer core paper station. Then, the tapered outer core paper that has been coated with glue and lifted comes into contact with the roll 8. The roll 8 adsorbs the outer core paper and continues to rotate, winding the outer core paper around the outside of the end of the roll paper to form a complete roll.

[0040] After winding is completed, the unloading cylinder 18 pushes the unloading gripper 17 to move horizontally to clamp the drum. Then the unloading cylinder 18 returns to its original position and pulls the entire drum off the winding roller 8, completing the automatic unloading.

[0041] In practical applications, a conveyor belt can be installed below the unloading gripper 17 to automatically feed the unloaded drum out.

[0042] In some examples, the first feeding trough 3, the second feeding trough 4, the third feeding trough 5, the fourth feeding trough 6, and the first transfer platform 11, the second transfer platform 12, the third transfer platform 13, and the fourth transfer platform 14 are all configured as vacuum negative pressure structures. Each feeding trough and each transfer platform has several negative pressure adsorption holes in its feeding area, which are connected to an external vacuum generator via air pipes. When the roll paper or outer tube paper is placed on the corresponding feeding trough or transfer platform, the vacuum generator is activated, causing the negative pressure adsorption holes to generate adsorption force, tightly adsorbing and fixing the roll paper or outer tube paper to the trough or platform surface. This prevents positional shifts or slippage during robotic arm transfer, pneumatic slide movement, folding, cutting, gluing, or rotation processes, ensuring positioning accuracy and stability during conveying and processing.

[0043] When the current workstation is completed or the material is ready for transfer, the vacuum generator can release the negative pressure according to the control command so that the horizontal feeding robot arm 7 or the transfer robot arm 15 can smoothly take away the material and enter the next workstation.

[0044] Through the coordinated operation of the above-mentioned units, this invention realizes fully automated conveying and assembly of roll paper and outer roll paper from feeding, processing, gluing, winding to unloading. It has a compact structure, stable operation, and effectively improves production efficiency and product quality.

[0045] Compared with the traditional manual winding method, the present invention has the following significant advantages: 1. High degree of automation, significantly improving production efficiency: This invention, through its integrated roll-head conveying unit and outer tube conveying unit, along with a translational feeding robotic arm 7, a transfer robotic arm 15, and multiple pneumatic slides and motor drives, achieves fully automated, step-by-step, and precise conveying of roll paper and outer tube paper from stacked raw materials to the winding station. Throughout the process, the folding of the roll paper, the cutting and shaping of the outer tube paper, the application of glue, and the unloading of the finished product all require no manual intervention, completely changing the inefficient traditional method of manual feeding, manual folding, and manual glue application. Compared to manual winding, this device can operate continuously, stably, and at high speed, significantly reducing the time per work cycle and substantially increasing output per unit time.

[0046] 2. High processing precision and good product consistency: Manual operation is prone to problems such as deviations in the folding angle of the roll end, inconsistent cutting dimensions of the outer roll, and uneven glue application. This invention integrates a folding assembly into the roll end conveying unit, including a folding die 42, a folding knife 43, and a folding cylinder 44. This allows for standardized folding and bending of the roll end, ensuring consistent folding angles and positions each time. The outer roll is precisely cut into the required conical structure using a cutter 131 in conjunction with an electric push rod 132. The glue roller 63 and glue gun 16 are controlled by a cylinder for consistent height and stable, controllable glue application. These designs ensure a strong bond at the beginning of each finished roll, a neat shape, and product consistency far superior to manual operation.

[0047] 3. Ingenious structural design and strong process coordination: The winding unit employs a double-conical winding roller 8 in conjunction with a rotating arm 81, achieving a two-step winding process of "winding the lead paper first, then the outer coil paper," with station switching automatically completed by a servo motor 82. Simultaneously, the rotary motor 61 of the fourth feeding trough 6 adjusts the angle of the lead paper, and the support plate 141 of the fourth transfer table 14 lifts the outer coil paper, ensuring precise contact between both and the winding roller 8. The unloading assembly includes unloading grippers 17 and an unloading cylinder 18, automatically removing the finished product after winding, forming a complete automated closed loop. The various units work collaboratively through reasonable timing control, avoiding the waiting and connection errors common in manual operation.

[0048] 4. Automatic waste collection, friendly working environment: During the process of cutting the outer tube paper into a conical structure, waste material is generated at the edges and corners. This invention provides a waste guide plate 133 and a waste discharge chute 134 on the back of the cutter 131. The waste material generated during cutting can automatically slide down and be discharged in a concentrated manner, which is convenient for collection and cleaning, reduces the frequency of manual waste cleaning, and keeps the machine 1 and its surrounding environment clean.

[0049] In summary, this invention solves the problems of low efficiency, poor accuracy, and high labor intensity of traditional manual roll-up methods, and provides a highly efficient, accurate, stable, and easy-to-maintain fully automatic roll-up conveyor device.
