The non-metallic isolation sleeve is sleeved between the shaft body and the inner wall of the mounting groove. The head is located on the side of the first side plate opposite to the second side plate, and the radial dimension of the head is greater than the radial dimension of the first through hole on the first side plate.

[0016] The suspension mechanism further includes a first locking nut, which is threadedly connected to one end of the shaft body away from the head and located on the side of the second side plate away from the first side plate.

[0035] Please see Figure 1 This application provides a handling device, including a loading device 200 and a motion drive device 100. The loading device 200 is used for loading or unloading material rolls. The loading device 200 is connected to the drive end of the motion drive device 100, enabling the motion drive device 100 to drive the loading device 200 to move, thereby realizing the transfer of the material rolls. Specifically, the motion drive device 100 can drive the loading device 200 to translate along a first horizontal direction and a second horizontal direction, and can also drive the loading device 200 to rise or fall, and can also drive the loading device 200 to rotate about a vertical axis. The first horizontal direction intersects the second horizontal direction, preferably, the first horizontal direction is perpendicular to the second horizontal direction.

[0036] The motion drive device 100 includes a first guide rail 10, a second guide rail 20, a rotating mechanism 30, and a lifting mechanism 40. The first guide rail 10 extends longitudinally along a first horizontal direction, and the second guide rail 20 extends longitudinally along a second horizontal direction. The motion drive device 100 also includes a suspension mechanism 50 and a moving drive mechanism. The suspension mechanism 50 and the moving drive mechanism are connected between the first guide rail 10 and the second guide rail 20, such that the second guide rail 20 is suspended on the first guide rail 10 by the suspension mechanism 50, and that the moving drive mechanism can drive the second guide rail 20 to move along the first guide rail 10 (i.e., move along the first horizontal direction).

[0037] The second guide rail 20 and the rotating mechanism 30 can also be connected by the suspension mechanism 50 and the moving drive mechanism, so that the rotating mechanism 30 is suspended on the second guide rail 20 by the suspension mechanism 50, and the moving drive mechanism can drive the rotating mechanism 30 to move along the second guide rail 20 (i.e., move along the second horizontal direction).

[0038] The lifting mechanism 40 is connected to the drive end of the rotating mechanism 30, and the rotating mechanism 30 can drive the lifting mechanism 40 to rotate. The loading device 200 is connected to the drive end of the lifting mechanism 40, so that the lifting mechanism 40 can drive the loading device 200 to rise and fall. Thus, under the driving action of the moving drive mechanism between the first guide rail 10 and the second guide rail 20, the loading device 200 moves along the first horizontal direction; under the driving action of the moving drive mechanism between the second guide rail 20 and the rotating mechanism 30, the loading device 200 rotates; and under the driving action of the lifting mechanism 40, the loading device 200 rises or falls.

[0039] Furthermore, two first guide rails 10 can be configured, arranged opposite to each other and parallel to each other. Two second guide rails 20 can also be configured, arranged opposite to each other and parallel to each other. Each second guide rail 20 is suspended from the two first guide rails 10 at both ends by two suspension mechanisms 50, that is, the two second guide rails 20 are suspended from the two first guide rails 10 by four suspension mechanisms 50.

[0040] It should be noted that the suspension mechanism 50 between the first guide rail 10 and the second guide rail 20 has a similar structure to the suspension mechanism 50 between the second guide rail 20 and the rotating mechanism 30. Therefore, the suspension mechanism 50 between the first guide rail 10 and the second guide rail 20 will be used as an example for explanation.

[0041] Please see Figure 2 and Figure 3In the embodiments of this application, the suspension mechanism 50 includes a sliding seat (not shown), a connecting seat 51, a pivot shaft 52, a non-metallic isolation sleeve 53, and a fixed seat 54. The sliding seat is disposed on the first guide rail 10 and is movable along the first guide rail 10. The connecting seat 51 is fixedly connected to the sliding seat and has a mounting groove A. The pivot shaft 52 passes through the mounting groove A on the connecting seat 51. The fixed seat 54 is connected to both ends of the pivot shaft 52, so that the fixed seat 54 is suspended on the connecting seat 51 through the pivot shaft 52. The non-metallic isolation sleeve 53 is sleeved between the outer side of the pivot shaft 52 and the inner wall of the mounting groove A, so that the non-metallic isolation sleeve 53 separates the pivot shaft 52 and the connecting seat 51, avoiding direct contact between the two and friction to generate metal dust. The above-mentioned moving drive mechanism can be drivenly connected to the sliding seat, so that the moving drive mechanism can drive the sliding seat to move along the first guide rail 10, thereby driving the loading device 200 to move along the first guide rail 10.

[0042] Specifically, the non-metallic isolation sleeve 53 is elastic, which allows a certain amount of floating between the connecting seat 51 and the pivot shaft 52, thereby compensating for errors and helping to reduce manufacturing and assembly difficulties.

[0043] Specifically, the non-metallic isolation sleeve 53 is a plastic sleeve, which serves two purposes: firstly, it isolates the pivot shaft 52 from the connecting seat 51, preventing the generation of metal powder due to wear; secondly, the plastic sleeve has a certain degree of elasticity, which can compensate for errors, thereby reducing manufacturing and assembly difficulties. Optionally, the non-metallic isolation sleeve 53 can be made of polyurethane.

[0044] In some embodiments, the fixing base 54 includes a first side plate 541, a base plate 545, and a second side plate 543. The first side plate 541 and the second side plate 543 are arranged opposite to each other, and the base plate 545 is connected between the first side plate 541 and the second side plate 543, so that the first side plate 541, the base plate 545, and the second side plate 543 are connected as a whole. The base plate 545 is fixedly connected to the second guide rail 20. A first through hole is provided on both the first side plate 541 and the second side plate 543, and the two ends of the pivot shaft 52 pass through the first through holes on the first side plate 541 and the second side plate 543, respectively, so that the fixing base 54 is suspended on the connecting base 51 by the pivot shaft 52. It should be noted that the first side plate 541, the base plate 545, and the second side plate 543 can be integrally formed, for example, by bending. In other embodiments, the first side plate 541, the base plate 545, and the second side plate 543 can also be fixed into a whole by welding or other assembly methods.

[0045] In a specific embodiment, the pivot shaft 52 includes a shaft body 521 and a head 523 fixedly connected to one end of the shaft body 521. The shaft body 521 is disposed through a first through hole on the first side plate 541, a mounting groove A on the connecting seat 51, and a first through hole on the second side plate 543. A non-metallic isolation sleeve 53 is fitted between the inner wall of the shaft body 521 and the mounting groove A, thereby isolating the shaft body 521 from the connecting seat 51 and preventing the generation of metal dust. The head 523 of the pivot shaft 52 is located on the side of the first side plate 541 opposite to the second side plate 543, and the radial dimension of the head 523 is larger than the radial dimension of the first through hole on the first side plate 541, thereby preventing the head 523 from passing through the first through hole on the first side plate 541. The suspension mechanism 50 also includes a first locking nut 58. The first locking nut 58 is threadedly connected to the end of the shaft body 521 opposite to the head 523 and is located on the side of the second side plate 543 opposite to the first side plate 541. Thus, by tightening the first locking nut 58, the first locking nut 58 and the head 523 together clamp the first side plate 541 and the second side plate 543 of the fixing seat 54, thereby locking the fixing seat 54, the pivot shaft 52 and the first locking nut 58 into one unit, preventing the pivot shaft 52 from detaching from the fixing seat 54. When disassembly is required, the first locking nut 58 is unscrewed from the shaft body 521, and then the pivot shaft 52 is pulled out.

[0046] Furthermore, the shaft body 521 has a first through hole 5211 extending radially along the shaft body 521 at the end away from the head 523. The suspension mechanism 50 also includes a first limiting pin 59 inserted into the first through hole 5211. The first locking nut 58 is located between the second side plate 543 and the first limiting pin 59, thereby preventing the first locking nut 58 from falling off from the end of the shaft body 521 away from the head 523 when it loosens.

[0047] In some embodiments, the connecting seat 51 is U-shaped. That is, the connecting seat 51 includes a first ear plate 511, an arc-shaped plate 515, and a second ear plate 513. The first ear plate 511 and the second ear plate 513 are arranged opposite to each other, and the arc-shaped plate 515 connects the first ear plate 511 and the second ear plate 513, so that the first ear plate 511, the arc-shaped plate 515, and the second ear plate 513 together enclose the aforementioned mounting groove A. Both the first ear plate 511 and the second ear plate 513 are fixedly connected to the sliding seat. The pivot shaft 52 is disposed through the mounting groove A, that is, the pivot shaft 52 is located between the first ear plate 511 and the second ear plate 513, and is located above the arc-shaped plate 515.

[0048] It should be noted that the first ear plate 511, the arc-shaped plate 515, and the second ear plate 513 of the connecting seat 51 can be integrally formed, for example, by stamping and bending. Of course, in other embodiments, the first ear plate 511, the arc-shaped plate 515, and the second ear plate 513 of the connecting seat 51 can also be fixed together as a whole by assembly processes such as welding.

[0049] In a specific embodiment, the sliding seat portion is located between the first ear plate 511 and the second ear plate 513, and this portion is named the connecting portion. The first ear plate 511, the second ear plate 513, and the connecting portion all have second through holes. The suspension mechanism 50 also includes a connector 55, which passes through the second through holes in the first ear plate 511, the connecting portion, and the second ear plate 513, thereby suspending the connecting seat 51 on the sliding seat using the connector 55. Preferably, the connector 55 passes through the second through holes in the first ear plate 511, the connecting portion, and the second ear plate 513 in a direction perpendicular to the axial direction of the pivot shaft 52.

[0050] Specifically, the connector 55 includes a rod portion 551 and a limiting portion 553 fixedly connected to one end of the rod portion 551. The rod portion 551 has a second through hole passing through the first ear plate 511, the connecting portion, and the second ear plate 513. The limiting portion 553 is located on the side of the first ear plate 511 opposite to the second ear plate 513, and the radial dimension of the limiting portion 553 is larger than the radial dimension of the second through hole on the first ear plate 511, thereby preventing the limiting portion 553 from passing through the second through hole on the first ear plate 511. The suspension mechanism 50 also includes a second locking nut 56 threadedly connected to the end of the rod portion 551 opposite to the limiting portion 553, and the second locking nut 56 is located on the side of the second ear plate 513 opposite to the first ear plate 511. Thus, by tightening the second locking nut 56, the second locking nut 56 and the limiting part 553 together clamp the first ear plate 511 and the second ear plate 513 of the connecting seat 51, thereby locking and fixing the connecting seat 51, the connecting piece 55 and the second locking nut 56 into one piece, preventing the connecting piece 55 from detaching from the connecting seat 51. When disassembly is required, the second locking nut 56 is unscrewed from the rod 551, and then the connecting piece 55 is pulled out.

[0051] Furthermore, a second through hole extending radially along the rod portion 551 is provided at the end of the rod portion 551 away from the limiting portion 553. The suspension mechanism 50 also includes a second limiting pin 57 inserted into the second through hole. The second locking nut 56 is located between the second ear plate 513 and the second limiting pin 57, thereby preventing the second locking nut 56 from falling off from the end of the rod portion 551 away from the limiting portion 553 when it loosens.

[0052] In a specific embodiment, at least two connectors 55 are provided, and each connector 55 is spaced apart in a direction parallel to the axial direction of the pivot shaft 52. In this way, the connecting seat 51 is simultaneously locked and fixed to the sliding seat by each connector 55, making the fixation between the sliding seat and the connecting seat 51 more secure and reliable. Figure 2 In the illustrated embodiment, there are two connectors 55. Of course, in other embodiments, the number of connectors 55 may be three or four, etc., and this is not limited here.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
