DETAILED DESCRIPTION

[0022] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] refer to Figures 1 to 8 : A transport device for transporting a paper roll to a paper rack includes a paper roll body 1, a transport mechanism, an adjustment mechanism, and a clamping unit. The two ends of the paper roll body 1 are symmetrically provided with connecting grooves 2, and the connecting grooves 2 are used to connect to the output end of the paper reel. The transport mechanism includes a first transport trolley 3, a second transport trolley 25, a telescopic chassis 46, a lifting bracket 4, and a lifting support 26. One end of the telescopic chassis 46 is connected to the first transport trolley 3, and the other end is connected to the second transport trolley 25. The lifting bracket 4 is arranged on the first transport trolley 3, and the lifting support 26 is arranged on the second transport trolley 25. The adjustment mechanism includes a rotator 27 and a visual sensor. The visual sensor is arranged on the lifting bracket 4, and the rotator 27 is arranged on the lifting support 26 (such as Figure 6 As shown in the figure, the clamping unit includes a clamping mechanism and an inner supporting mechanism. The clamping mechanism is arranged on the lifting bracket 4. The clamping mechanism has two clamping output ends that can move toward each other. Each clamping output end is provided with a clamping wheel frame 9. The clamping wheel frame 9 is provided with two clamping rollers 10. The inner supporting mechanism is arranged on the rotator 27. The inner supporting mechanism is used to support the inner edge of the end of the paper roller body 1 from the circumferential direction.

[0024] When the device is in operation, the telescopic chassis 46, the first transport trolley 3 and the second transport trolley 25 are adjusted to a suitable spacing, and then synchronously moved horizontally to the placement of the paper roller body 1, and then the telescopic chassis 46 is retracted a certain distance, and then the lifting bracket 4 and the lifting support 26 are lifted to a certain height. After the lifting bracket 4 is lifted, the two clamping output ends of the clamping mechanism move, driving the clamping roller 10 on the clamping wheel frame 9 to clamp one end of the paper roller body 1, and at the same time, the inner support mechanism tightens the inner edge of the other end of the paper roller body 1 from the circumferential direction. At this point, the paper roller body 1 completes the transfer from the placement to the transport mechanism, and then the visual sensor (the visual sensor is a mature existing technology and will not be described in detail here) monitors the paper roller body at this end clamped by the clamping mechanism. Whether the connecting groove 2 on 1 (the connecting groove 2 is set to face upward for easy connection with the paper winder) is facing upward. If the connecting groove 2 faces upward, the first transport vehicle 3 and the second transport vehicle 25 run synchronously to transport the paper roller body 1 to the paper roller storage place on the paper rack, and then the clamping mechanism and the inner support mechanism release the paper roller body 1, and the equipment is reset to facilitate the next transportation of the paper roller body 1; if the connecting groove 2 is not facing upward, the rotator 27 of the adjustment mechanism drives the inner support mechanism to rotate, and then drives the paper roller body 1 to rotate and adjust. With the cooperation of the visual sensor, the connecting groove 2 is finally adjusted to face upward, eliminating manual adjustment, saving time, and avoiding human participation to prevent the risk of crushing.

[0025] In order to show the detailed structure of the clamping mechanism, the following features are also set: The clamping mechanism includes a supporting vertical plate 24 fixedly arranged on the lifting bracket 4, a bearing block 5 fixedly arranged on the supporting vertical plate 24, two supporting bases 22 fixedly arranged on the lifting bracket 4 in a symmetrical state, a power cylinder 23 with a bottom rotationally arranged on each supporting base 22 and two clamping arms 6 symmetrically arranged on the bearing block 5, the bottom end of each clamping arm 6 is rotatably connected to the bearing block 5, the two power cylinders 23 correspond one-to-one to the two clamping arms 6, the output shaft of each power cylinder 23 is hinged to the corner of the corresponding clamping arm 6, and each clamping arm 6 is provided with a clamping wheel frame 9.

[0026] The clamping arm 6 is the clamping output end of the clamping mechanism.

[0027] When the device is running, the two power cylinders 23 operate synchronously, and the output shaft of the power cylinder 23 drives the clamping arm 6 to flip around the connection with the bearing block 5, and in this process, the power cylinder 23 also rotates adaptively on the support base 22. After the clamping arm 6 flips, it drives the clamping wheel frame 9 to flip close to the paper roller body 1, and then clamps the paper roller body 1 through the clamping roller 10.

[0028] In order to ensure that the device can clamp paper roll bodies 1 of various diameters, the following features are also provided: The clamping mechanism also includes a limit box 7 fixedly provided on each clamping arm 6, a sliding support block 11 slidably provided in each limit box 7, an adjusting screw 8 rotatably provided in the limit box 7 and a drive motor 12 fixedly provided at the end of the limit box 7. A clamping wheel frame 9 is fixedly provided on each sliding support block 11, the adjusting screw 8 is threadedly connected to the sliding support block 11, and the output shaft of the drive motor 12 is coaxially fixedly connected to the adjusting screw 8.

[0029] When it is necessary to clamp paper roll bodies 1 of different diameters, the driving motor 12 drives the adjusting screw 8 to rotate. The adjusting screw 8 rotates under the action of the thread, so that the sliding support block 11 moves along the length of the limit box 7, thereby adjusting the position of the clamping wheel frame 9, so that the clamping roller 10 can perfectly fit the paper roll body 1 when the equipment clamps paper roll bodies 1 of different diameters.

[0030] In order to ensure that the clamping mechanism can better clamp the paper roller body 1, the following features are also specifically provided: The clamping mechanism also includes a supporting slider 15 slidably arranged on the supporting block 5, a supporting plate 16 fixedly arranged on the supporting slider 15, a supporting wheel frame 17 elastically connected to the supporting plate 16, and a plurality of supporting rollers 18 rotatably arranged on the supporting wheel frame 17 at equal intervals along the arc of the supporting wheel frame 17. The supporting slider 15 is transmission-connected to the two clamping arms 6.

[0031] When the two clamping arms 6 flip and clamp the paper roller body 1, the movement of the clamping arms 6 drives the supporting slider 15 to move upward, and the upward movement of the supporting slider 15 drives the supporting plate 16 to move, and the movement of the supporting plate 16 drives the supporting wheel frame 17 to move, thereby driving the supporting roller 18 to press against the paper roller body 1, and cooperating with the two sets of clamping rollers 10 to achieve clamping of the paper roller body 1 in three directions, so that when the subsequent device adjusts the paper roller body 1, the paper roller body 1 can be stable.

[0032] In order to demonstrate the connection relationship between the clamping arm 6 and the supporting slider 15, the following features are specifically provided: A toggle gear 13 is fixedly provided at one end of each clamping arm 6 connected to the supporting block 5, and a connecting rack 21 is fixedly provided on both sides of the supporting slider 15. Two reversing gears 14 are symmetrically rotated on the supporting block 5, and the toggle gear 13 is connected to the connecting rack 21 on the corresponding side through the reversing gear 14.

[0033] In the process of the clamping arm 6 swinging to clamp the paper roller body 1, the movement of the clamping arm 6 will drive the toggle gear 13 to rotate, and the rotation of the toggle gear 13 will drive the reversing gear 14 to rotate. The reversing gear 14 rotates and then engages with the connecting rack 21, causing the supporting slider 15 to move upward under the drive of the connecting rack 21.

[0034] In order to demonstrate the elastic connection structure between the supporting wheel frame 17 and the supporting plate 16, the following features are also specifically provided: Two limiting slide rods 19 are symmetrically arranged on the supporting wheel frame 17. The limiting slide rods 19 pass through the supporting plate 16. A return spring 20 is coaxially sleeved on each limiting slide rod 19. A limiting ring is fixedly provided on the end of each limiting slide rod 19 away from the supporting wheel frame 17. One end of the return spring 20 is against the supporting wheel frame 17, and the other end is against the supporting plate 16.

[0035] In the initial state, the return spring 20 is extended and the limit ring is against the supporting plate 16. When the supporting plate 16 is driven upward by the supporting slider 15 to press against the paper roller body 1, the return spring 20 will be compressed and the limit slide 19 will adaptively slide through the supporting plate 16, thereby causing the supporting roller 18 to always have a tendency to press against the paper roller body 1.

[0036] In order to show the detailed structure of the internal support mechanism, the following features are also set: The inner support mechanism includes a rotating disk 28 coaxially connected to the output shaft of the rotator 27, two connecting support plates 29 symmetrically fixed on the rotating disk 28, a limiting outer cylinder 30 coaxial with the rotating disk 28 and fixed to the two connecting support plates 29, a bearing outer ring 31 coaxially fixed to the end of the limiting outer cylinder 30 away from the rotating disk 28, a plurality of annular hinged protrusions 32 fixedly provided on the bearing outer ring 31, a connecting swing arm 33 hingedly provided on each hinged protrusion 32, a plurality of annular positioning protrusions 34 formed on the inner wall of the bearing outer ring 31, a movable inner cylinder 35 coaxially provided in the limiting outer cylinder 30, a plurality of annular limiting grooves 40 opened on the outer wall of the movable inner cylinder 35, a movable inner ring 36 coaxially provided at the end of the movable inner cylinder 35 away from the rotating disk 28, and a plurality of pairs of annular movable inner rings 36 provided on the movable inner cylinder 35. The hinged ears 37 on the movable inner ring 36, several L-shaped swing arms 38 arranged in a ring shape on the movable inner ring 36, an inner support arc block 39 fixedly arranged on the end of each L-shaped swing arm 38 away from the movable inner ring 36, and a toggle for driving the movable inner cylinder 35 to move along the axis of the limiting outer cylinder 30, the positioning protrusions 34 correspond one-to-one with the limiting grooves 40 and are slidably connected, several hinged protrusions 32 correspond one-to-one with several pairs of hinged ears 37 (the one-to-one correspondence here means that the number of hinged protrusions 32 and hinged ears 37 is consistent), the L-shaped swing arms 38 correspond one-to-one with the hinged ears 37 and the corners of the L-shaped swing arms 38 are rotatably connected to the hinged ears 37, several connecting swing arms 33 correspond one-to-one with several L-shaped swing arms 38, and the end of the connecting swing arm 33 away from the hinged protrusion 32 is rotatably connected to the end of the L-shaped swing arm 38 away from the inner support arc block 39.

[0037] When the device is running, the toggle drives the movable inner cylinder 35 to gradually approach the paper roller body 1 along the axis of the limiting outer cylinder 30. The movement of the movable inner cylinder 35 drives the movable inner ring 36 to move. The movement of the movable inner ring 36 drives the L-shaped swing arm 38 to move. After the L-shaped swing arm 38 moves, it is limited by the connecting swing arm 33, causing the L-shaped swing arm 38 to rotate around the connection with the hinge ear 37, so that the L-shaped swing arm 38 flips, thereby driving the inner support arc block 39 to synchronously tighten the paper roller body 1, and in the movable When the movable inner cylinder 35 moves, the limiting groove 40 and the positioning ridge 34 ensure that the movable inner cylinder 35 will not deflect when it is moved by the toggle device in the limiting outer cylinder 30; when it is necessary to adjust the rotation of the paper roller body 1, the rotator 27 drives the rotating disk 28 to rotate, and the rotation of the rotating disk 28 drives the limiting outer cylinder 30 to rotate through the connecting support plate 29, and the rotation of the limiting outer cylinder 30 drives the movable inner cylinder 35 to rotate, so that the entire inner support mechanism supports the paper roller body 1 to rotate.

[0038] In order to show the detailed structure of the toggle, the following features are also set: The toggle device includes a toggle inner cylinder 41 that is coaxially rotatably arranged on one end of the limiting outer cylinder 30 near the rotating disk 28, a worm gear ring 42 that is coaxially fixed on the toggle inner cylinder 41, a mounting bracket 43 that is fixed on the limiting outer cylinder 30, a worm 44 that is rotatably arranged on the mounting bracket 43, and a power motor 45 that is fixed on the mounting bracket 43. The output shaft of the power motor 45 is coaxially fixedly connected to the worm 44, the worm 44 is engaged with the worm gear ring 42, and the toggle inner cylinder 41 is threadedly connected to the movable inner cylinder 35.

[0039] When the device is running, the power motor 45 drives the worm 44 to rotate, the rotation of the worm 44 drives the worm gear ring 42 to rotate, the rotation of the worm gear ring 42 drives the shifting inner cylinder 41 to rotate, and the rotation of the shifting inner cylinder 41 causes the movable inner cylinder 35 to move along the axis of the limiting outer cylinder 30 under the action of the thread.

[0040] In order to ensure that the inner supporting arc block 39 has a better tightening effect when it is pressed against the inner edge of the end of the paper roller body 1, the following features are specifically provided: The inner supporting arc blocks 39 are all made of wear-resistant rubber.

[0041] When the inner supporting arc block 39 contacts the paper roller body 1 , the inner supporting arc block 39 made of wear-resistant rubber material can provide greater friction, ensuring stable operation of the equipment.

[0042] The operating principle of this device is as follows: The telescopic chassis 46 adjusts the distance between the first and second transport trolleys 3 and 25 to match the length of the paper roll 1. The trolleys then move horizontally to the location where the paper roll 1 is placed. The telescopic chassis 46 then retracts a certain distance. Subsequently, the lifting bracket 4 and the lifting support 26 rise synchronously, allowing the clamping and inner support mechanisms to reach their operating positions. At this point, the power cylinder 23 propels the clamping arm 6 to swing around the pins of the bearing block 5, driving the two sets of clamping rollers 10 on the clamping wheel frame 9 to tightly grip the outer edge of the paper roll 1 from both sides. Simultaneously, the inner support mechanism's actuator drives the movable inner cylinder 35 axially. Through the interlocking L-shaped swing arm, the inner support arc 39 expands radially, supporting the inner wall of the paper roll 1 from the inside. A visual sensor monitors the orientation of the connecting groove 2 on the paper roll 1 in real time. If an angular deviation is detected that exceeds a set threshold, the rotator 27 activates the entire inner support mechanism, driving the paper roll 1 to rotate synchronously until the groove faces straight up. Finally, the transport vehicle travels at a pre-set speed to the target position of the paper rack. The clamping and internal support mechanisms successively release the paper roll body 1, and all moving parts return to their initial states, ready for the next transport of the paper roll body 1. The entire system, through the linkage between mechanical components and visual feedback, achieves fully automated operations, from gripping the paper roll body 1, posture adjustment, to precise placement. The action sequence of each actuator is coordinated uniformly by the controller, ensuring a stable and efficient transport process.

[0043] The above embodiments merely represent one or several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
