Description

TECHNICAL FIELD

[0002] At present, for some large-sized coils, such as steel coils, aluminum coils, etc., in order to facilitate the later transportation, a pallet is generally used to carry the coils. That is, after the coils are wound, the coils are transferred to a wooden pallet by a transfer device, and then the whole is transported.

[0003] In the process of transferring the coils to the pallet, in order not to damage the outer surface of the coils, the transfer device usually adopts the way of clamping at both ends. For example, the applicant discloses a loading device and a loading method suitable for steel coils in the patent CN120328194A. The application enables the loading vehicle carrying the steel coils to travel along the guide rail from the coil loading position to the coil loading position, and the travel direction is not easy to deviate. The structure of the guide rail is flat, and the gravity of the steel coils is not only transferred to the guide rail, but also the loading vehicle runs more stably, effectively avoiding damage to the steel coils caused by shaking, and reducing the waste of the steel coils. However, in actual use, it is found that the device can only place the steel coils in a horizontal position on the wooden pallet, and the horizontal placement of the steel coils will bring certain safety hazards to the later transportation. At the same time, the steel coils will bear a large instantaneous impact force in the moment of falling, which is not conducive to the guarantee of the quality of the steel coils. Therefore, it is of great practical significance to design a transfer device that can place the steel coils in a vertical position on the pallet with less damage to the steel coils.

[0022] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings.

[0023] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] The present invention will be further described below with reference to specific embodiments.

[0025] like Figures 1-3 As shown, a roll flipping device according to this embodiment includes a frame 100 and a flipping mechanism 200 rotatably mounted on the frame 100. The flipping mechanism 200 includes a flipping frame 210 composed of a first platform 211 and a second platform 212 that are perpendicular to each other, and a drive source 220 for driving the flipping frame 210 to flip.

[0026] Preferably, the drive source 220 can be a hydraulic cylinder or a pneumatic cylinder as used in the prior art, which will not be described in detail here.

[0027] The first platform 211 is provided with several rollers 230, which form a support surface for supporting the pallet 600; at the same time, the rollers 230 can transport the pallet 600 to facilitate the adjustment of its position.

[0028] The second platform 212 is provided with a channel 2122, one end of which is open and the other end extends to the first platform 211. Supporting parts 2121 are formed on both sides of the channel 2122 to support the roll material 700.

[0029] Preferably, the support portion 2121 is inclined inward to ensure stable support for the roll 700. Simultaneously, the support portion 2121 is a polyurethane pad to prevent scratches on the outer peripheral wall of the roll 700.

[0030] In addition, a traveling mechanism 300 is provided in the channel 2122 to lift and transport the roll 700 on the bearing part 2121, so that the end of the roll 700 is close to the pallet 600.

[0031] In the initial state of the roll flipping device of this embodiment, the tray 600 is located on the first platform 211 and the first platform 211 is in a vertical state; the roll 700 is placed horizontally on the second platform 212 and the second platform 212 is in a horizontal state; at the same time, the traveling mechanism 300 is in a descending state.

[0032] During operation, the traveling mechanism 300 first moves upward, lifting the roll 700 on the second platform 212, and then moves the roll 700 towards the first platform 211. When the end of the roll 700 contacts the pallet 600, the traveling mechanism 300 stops moving. Next, the drive source 220 is activated to rotate the tilting frame 210 by 90 degrees, so that the roll 700 is placed vertically on the pallet 600. At the same time, throughout the tilting process, the end of the roll 700 remains in contact with the pallet 600, which effectively reduces the instantaneous impact force on the roll 700.

[0033] refer to Figure 4 As shown, in some embodiments, the walking mechanism 300 includes an upper support 310 and a lower support 320 arranged vertically. The lower support 320 slides against the inner wall of the channel 2122 via a slide rail 330. The lower support 320 is also connected to a drive assembly 350 for driving the lower support 320 to translate along the slide rail 330.

[0034] The upper support 310 is provided with a saddle 340, and the upper support 310 and the lower support 320 are connected by a lifting component 360. The lifting component 360 can drive the upper support 310 and the saddle 340 on it to move up and down.

[0035] Meanwhile, a rotating assembly 370 for driving the saddle 340 to rotate is provided between the saddle 340 and the upper support 310.

[0036] It should be noted that the aforementioned drive component 350, lifting component 360 and rotating component 370 may adopt existing technologies, and no specific limitations are made here.

[0037] In this embodiment, a coil turning device is provided. The walking mechanism 300, through the setting of the driving component 350, the lifting component 360 and the rotating component 370, can lift, translate and rotate the steel coil through the saddle 340, so as to adjust the steel coil to enter the roller transport position in the correct posture, so as to realize the two different placement of the steel coil, namely vertical and horizontal.

[0038] Figure 7 , Figure 9 The roll 700 is placed vertically on the pallet 600. Before the flipping frame 210 flips the roll, it is necessary to ensure that the axis of the roll 700 is aligned with the axis of the channel 2122. At the same time, the pallet 600 on the first platform 211 should be a vertical pallet 610.

[0039] Figure 8 , Figure 10 The diagram shows the roll material 700 placed horizontally on the pallet 600. Before the flipping frame 210 flips the roll material, it must be ensured that the axis of the roll material 700 is perpendicular to the axis of the channel 2122. Simultaneously, the pallet 600 on the first platform 211 must be a horizontal pallet 620. Both the horizontal pallet 620 and the vertical pallet 610 are existing technologies, and their specific structures will not be described in detail.

[0040] refer to Figure 2 , Figure 4 As shown, in one specific embodiment of the drive assembly 350, the drive assembly 350 includes a walking motor 351 and a rack 352; wherein, the walking motor 351 is mounted on the lower support 320, the rack 352 is mounted on the side wall of the channel 2122, and the walking motor 351 and the rack 352 are meshed and driven by a transmission gear 353.

[0041] When the walking motor 351 is started, the saddle 340 can move horizontally through the meshing transmission between the transmission gear 353 and the rack 352.

[0042] As one specific embodiment of the lifting component 360, the lifting component 360 includes a guide post 361, one end of which is connected to the upper support 310, and the other end is slidably connected to the lower support 320 through a bushing 362.

[0043] Meanwhile, the bottom of the lower bracket 320 is equipped with a power source 363 for driving the guide column 361 to move up and down. The power source 363 can be a cylinder or a hydraulic cylinder, and no specific limitation is made here.

[0044] As one specific embodiment of the rotating assembly 370, the rotating assembly 370 includes a slewing bearing 371 and a rotary motor 372. The slewing bearing 371 is fixed to the upper bracket 310 by its inner ring and connected to the saddle 340 by its outer ring.

[0045] A rotary motor 372 is mounted on the upper support 310. The output end of the rotary motor 372 meshes with the external teeth of the slewing bearing 371 through a transition gear 373. When the rotary motor 372 is started, the saddle 340 is rotated by the meshing transmission between the transition gear 373 and the external teeth of the slewing bearing 371 through the outer ring of the slewing bearing 371.

[0046] In some embodiments, the first platform 211 is also provided with a clamping mechanism 400 for clamping the pallet 600 to prevent the vertically placed pallet 600 from tipping over, thereby affecting the normal flipping operation.

The extending direction of each mounting frame 410 is consistent with the distribution direction of the rollers 230, and the mounting frame 410 is provided with a plurality of clamping blocks 430 located between adjacent rollers 230.

[0048] Meanwhile, the slider 420 is connected to a telescopic cylinder 440, which is used to drive the clamping block 430 to clamp and release the tray 600.

[0049] During operation, the second platform 212 is initially kept unloaded, meaning no roll 700 is placed on the second platform 212, and the first platform 211 is rotated to a horizontal position. At this time, the free end of the clamping block 430 extends above the roller 230 through the gap between the adjacent rollers 230. Then, the pallet 600 is placed on the first platform 211, and the roller 230 moves the pallet 600 to a designated position. Next, the telescopic cylinder 440 is activated, which moves the clamping block 430 to externally clamp or internally tighten the pallet 600. Subsequently, the second platform 212 is rotated to a horizontal position to prepare for the subsequent flipping operation of the roll 700.

[0050] Furthermore, the mounting bracket 410 is also provided with a synchronization assembly 450 for driving the two sliders 420 to move synchronously. The synchronization assembly 450 includes a rotating rod 451 hinged to the mounting bracket 410 at its center. The rotating rod 451 is located between the two sliders 420, and the two free ends of the rotating rod 451 are hinged to the corresponding sliders 420 through their respective connecting rods 452.

[0051] This embodiment of the roll flipping device, through the clamping mechanism 400, can clamp the pallet 600 to prevent the vertically placed pallet 600 from tipping over, thereby affecting the normal flipping operation. Simultaneously, the synchronization component 450 further ensures the stability of the pallet 600 clamping.

[0052] Furthermore, the mounting bracket 410 is also provided with a guide assembly 460 for guiding the movement of the mounting bracket 410. Specifically, the guide assembly 460 includes a guide shaft 461, which is mounted on the mounting bracket 410 via a support 462, and both ends of the guide shaft 461 are connected to the corresponding sliders 420 via linear bearings 463.

[0053] In some other embodiments, the first platform 211 is also provided with a positioning mechanism 500 for limiting the movement of the pallet 600.

[0054] Specifically, refer to Figure 6 As shown, the positioning mechanism 500 includes a movable block 510 slidably disposed on the first platform 211. The movable block 510 is provided with a pair of limiting plates 520 for limiting the pallet 600 carried by the roller 230, and the two limiting plates 520 have space for the saddle 340 to enter.

[0055] Meanwhile, the movable block 510 is connected to a moving component 530 for driving the movable block 510 to move. The moving component 530 includes a moving motor 531 and a ball screw 532; wherein, one end of the ball screw 532 is connected to the movable block 510, and the other end is connected to the output end of the moving motor 531 through a sprocket unit 533.
