[0002] In the paper roll production and conveying workshop, after the paper rolls are cut on the slitting machine, they need to be unrolled and transferred to the core loading station. The process here is as follows: the manual first moves the unrolled paper roll to the unrolling position of the slitting machine, then the manual rotates the rotating arm on the slitting machine to move the cut paper rolls to the unrolled paper roll, then the manual moves the unrolled paper roll with the paper rolls out, and then the manual transports the paper rolls onto the pallet, then the pallet is transferred to the core loading station, and then the manual moves the paper rolls from the pallet onto the core loading station mandrel.
[0003] In actual operation, due to the high positioning accuracy requirements of the slitting paper unloading position and the paper roll unloading carriage, it is dangerous to manually rotate the slitting paper unloading arm. Manually moving the paper roll multiple times can easily damage the paper roll, and the operation is cumbersome and laborious. Utility Model Content

[0031] Example 1:
[0032] Please see Figures 1-4 The floating positioning mechanism of this utility model includes:
[0033] The support component A includes a base 1, a universal ball 2 mounted on the base 1, and a support platform 3 for supporting materials floating on the universal ball 2.
[0034] The positioning drive assembly 4 includes a mounting frame 41, with a positioning arm 42 and a toggle arm 43 slidably connected to both ends of the mounting frame 41. Both the positioning arm 42 and the toggle arm 43 slide on the mounting frame 41 via a first linear drive component 44. The telescopic end of the first linear drive component 44, which drives the toggle arm 43, is equipped with a mounting plate 46 that is slidably connected to the mounting frame 41. The mounting plate 46 is provided with a rotating component 45 for rotating the toggle arm 43.
[0035] Positioning blocks 31 are installed in the center of both sides of the support platform 3, and V-shaped grooves 32 are opened on the outer side of both positioning blocks 31.
[0036] The positioning arm 42 and the actuating arm 43 are used to form an axis between the ends that contact the two positioning blocks 31, which coincides with the positioning axis 13 of the material.
[0037] The two positioning blocks 31 are on the same horizontal line, and the positioning arm 42 and the toggle arm 43 are on the same horizontal plane as the corresponding positioning blocks 31.
[0038] Working principle:
[0039] As the entire carrier assembly A moves the carrier platform 3 toward the positioning arm 42, the corresponding positioning block 31 on the carrier platform 3 comes into contact with the positioning arm 42, the carrier assembly A stops moving, and then the positioning arm 42 retracts under the activation of the first linear drive component 44. The retracted positioning arm 42 will drive the carrier platform 3 to rotate on the universal ball 2 and make the center of the corresponding positioning block 31 located on the positioning axis 13.
[0040] Then the rotating component 45 is activated, causing the actuating arm 43 to rotate parallel to the positioning arm 42. During the rotation, if it contacts the inner wall of the V-groove 32 in the corresponding positioning block 31, the first linear drive component 44 will carry the rotating component 45 and the actuating arm 43 to retract as a whole. This will cause the positioning block 31, which is not located on the positioning axis 13, to be moved to the positioning axis 13 under the rotation of the support platform 3. This will enable the floating positioning of the support platform 3 based on the position of the base 1, ensuring that the material center axis on the support component A located on the support platform 3 can be adjusted to the pre-set positioning axis 13. This method can be applied to equipment with high requirements for the positioning of the material center axis after material conveying and transfer. Furthermore, it does not restrict the mobile device that drives the support component A and does not require positioning of the mobile device that drives the support component A. It has good application prospects, especially for mobile devices without fixed tracks, as it does not require multiple adjustments to the material center axis by driving the mobile device.
[0041] Specifically, in this embodiment, the rotating component 45 uses an electric telescopic rod in conjunction with a connector or a swing arm to make the actuating arm 43 swing on the mounting plate 46. The rotating component 45 can also use a motor to connect the actuating arm 43 to make it rotate.
[0042] Specifically, both the positioning arm 42 and the actuating arm 43 include a connecting part 4a and a contact part 4b. The connecting part 4a is used to connect with the first linear drive component 44. The end of the contact part 4b is provided with a roller 4c, and the sum of the lengths of the end of the roller 4c and the contact part 4b is greater than the depth of the V-groove 32 on the positioning block 31, thereby ensuring smooth contact between the positioning arm 42 and the actuating arm 43 and the V-groove 32, and ensuring contact with the center of the V-groove 32.
[0043] The positioning arm 42 and the mounting bracket 41 form an L-shaped station for accommodating the carrier component A, which facilitates the mobile device to drive the carrier component A to be positioned using the positioning drive component 4.
[0044] Example 2:
[0045] Please see Figure 3 and Figure 4 As a further improvement to Embodiment 1, unlike Embodiment 1, the bearing component A also includes a limiting member 5 installed between the bearing platform 3 and the base 1, and a force-bearing sleeve plate 6 sleeved on the limiting member 5 is fixedly connected to the bottom of the bearing platform 3. An adjustment groove 7 is provided on the force-bearing sleeve plate 6, and an active area 8 is provided between the limiting member 5 and the adjustment groove 7. The force-bearing sleeve plate 6 on the bearing platform 3 can rotate on the base 1 by utilizing the active area 8 between it and the limiting member 5.
[0046] The omnidirectional balls 2 are evenly distributed on the upper surface of the base 1 on both sides of the force-bearing sleeve plate 6.
[0047] The support assembly A also includes an adjustment assembly 9 for adjusting the support platform 3 to the positioning axis 13.
[0048] The adjustment assembly 9 includes a second linear drive component 91 and a guide rail pair 92 installed between the base 1 and the limiting member 5. The second linear drive component 91 is used to drive the limiting member 5 to move in the adjustment groove 7.
[0049] Working principle:
[0050] When the load-bearing component A is moving, the limiting member 5 is in contact with the inner wall of the adjustment groove 7 on the force-bearing sleeve 6. When the load-bearing component A moves to contact the positioning arm 42, the second linear drive component 91 starts and the limiting member 5 moves in the adjustment groove 7 to generate the active area 8.
[0051] Then, when the positioning arm 42 retracts and drives the bearing platform 3 to rotate, the central axis of the bearing platform 3 is set at an angle relative to the positioning axis 13. The second linear drive component 91 is activated again, so that the limiting component 5 retracts to contact the inner wall of the adjustment groove 7 and pushes the bearing platform 3. Because one side of the bearing platform 3 is limited by the positioning block 31 and the positioning arm 42, the force-bearing sleeve 6 will cause the central axis of the bearing platform 3 to coincide with the positioning axis 13 under the push of the second linear drive component 91.
[0052] That is, by using the second linear drive component 91 to move the limiting component 5 in the adjustment groove 7, the central axis of the bearing platform 3 can be adjusted to the positioning axis 13 independently, or it can be used in conjunction with the rotation and retraction of the actuating arm 43 to rotate the bearing platform 3, thereby reducing the force on the actuating arm 43 and improving the service life of the equipment.
[0053] Furthermore, if the second linear drive component 91 causes the limiting component 5 to adjust the support platform 3 independently, the subsequent rotation and retraction of the toggle arm 43 can achieve the function of detecting whether the central axis of the support platform 3 is located on the positioning axis 13.
[0054] The limiting component 5 is a trapezoidal frame, and the adjusting groove 7 is a trapezoidal groove that is adapted to the trapezoidal frame. The outer side of the trapezoidal groove is open. The trapezoidal limiting component 5 can play a guiding and positioning role when retracting, ensuring that it does not float in the front, back, left and right.
[0055] Example 3:
[0056] A paper roll AGV trolley includes a carrier component A as described in Embodiment 1 and Embodiment 2, and a vehicle body 12. The carrier component A is mounted on the vehicle body 12, and the carrier platform 3 of the carrier component A is provided with a carrier frame 10 for carrying the roll material in the center.
[0057] The inner wall of the carrier frame 10 is provided with carrier blocks 11 on both sides to form a gripping gap between the coil and the carrier frame 10. The carrier blocks 11 on both sides are arranged symmetrically in a V-shape.
[0058] Working principle:
[0059] In this embodiment, the AGV trolley body 12 can carry the carrier component A to move. When the V-shaped groove 32 of the positioning block 31 on the carrier component A comes into contact with the positioning rod, positioning arm 42 and other structures set on the workstation, the carrier platform 3 can initially rotate carrying the rolled material. Then, the second linear drive component 91 causes the limiting component 5 to push the carrier platform 3 to move, thereby realizing the adjustment of the material center axis on the AGV trolley and reducing the accuracy requirements for the AGV trolley to carry the material into the workstation.

Various modifications and variations can be made to this utility model by those skilled in the art.
