Description

Technical Field

[0001] This application relates to the field of roll transfer equipment technology, and more particularly to clamping equipment for transferring rolls. Background Technology

[0002] The freshly produced rolls are moved from the winding equipment in a horizontal position. To facilitate storage, clamping equipment is used to fix the horizontal rolls and then adjust them to a vertical position before placing them on a pallet. This prevents the rolls from rolling during storage and makes it easier to handle them using forklifts or other mechanical equipment.

[0003] Clamping devices are typically connected to the chain of an electric hoist via hooks. The electric hoist provides upward pulling force to help the operator overcome the weight of the clamping device and the coiled material to lift and / or transfer the material. The operator only needs to control the direction of movement of the clamping device. However, existing clamping devices have only one connection point with the electric hoist. Therefore, when clamping coiled material of different weights, the center of gravity of the clamping device will shift to different degrees. When the clamping device clamps a horizontally positioned coiled material, the overall center of gravity will be biased towards the side where the coil is located. The heavier the coiled material, the greater the degree of center of gravity shift, and the greater the tilt of the clamping device. To ensure that the clamping device can hold and release the coiled material stably, the operator needs to exert considerable effort to maintain the balance of the clamping device, which is quite strenuous.

The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0024] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and 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, the above terms should not be construed as limitations on this application.

[0025] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0026] refer to Figures 1 to 2 A preferred embodiment of the clamping device for transferring coiled material according to this application will be described in detail below. The clamping device for transferring coiled material is connected to a suspension device, such as an electric hoist. The coiled material includes a drum and a strip wound around the outer periphery of the drum.

[0027] Preferably, the barrel forms an insertion channel that extends along the axial direction of the barrel and communicates with the outside.

[0028] Specifically, the clamping device for transferring the coil includes a mounting frame 10, a clamping mechanism 20, and a posture adjustment mechanism 30.

[0029] The mounting frame 10 includes a mounting body 11 and a suspension member 12. The mounting body 11 has a high end portion 111 and a low end portion 112 below the high end portion 111. The suspension member 12 is mounted on the high end portion 111 and is adapted to be connected to a suspension device. A clamping mechanism 20 is rotatably mounted on the low end portion 112 and is used to clamp the rolled material. By moving the mounting frame 10, the clamping mechanism 20 and the rolled material clamped by the clamping mechanism 20 are moved to transfer the rolled material. Specifically, by controlling the operation of the suspension device, the operator can manipulate the mounting frame 10 to move, causing the mounting frame 10 to move the clamping mechanism 20 and transfer the rolled material.

[0030] The posture adjustment mechanism 30 is installed on the mounting body 11, and the clamping mechanism 20 is connected to the posture adjustment mechanism 30. The posture adjustment mechanism 30 is used to drive the clamping mechanism 20 to rotate along the vertical plane in order to adjust the placement posture of the coil held by the clamping mechanism 20.

[0031] refer to Figure 1 and Figure 2In one embodiment, in the initial state, the roll is placed vertically. After the roll is clamped by the clamping mechanism 20, the posture adjustment mechanism 30 drives the clamping mechanism 20 to rotate so that the clamped roll turns to a horizontal position. At this time, the roll changes from a vertical posture to a horizontal posture.

[0032] In another embodiment, in the initial state, the roll is placed horizontally. After the roll is clamped by the clamping mechanism 20, the attitude adjustment mechanism 30 drives the clamping mechanism 20 to rotate so that the clamped roll turns to a vertical position. At this time, the roll changes from a horizontal posture to a vertical posture.

[0033] refer to Figure 1 , Figure 2 and Figure 4 It is worth mentioning that the suspension member 12 has multiple mounting holes 1201 spaced apart along the axial direction parallel to the horizontally positioned coil material, and the suspension device is connected to any of the mounting holes 1201. By adjusting the connection of the suspension device to different mounting holes 1201, the center of gravity of the clamping device for transferring the coil material can be adjusted so that the clamping device for transferring the coil material remains balanced after adjusting coil materials of different weights to a horizontal position, which facilitates the operation of the clamping device for transferring the coil material by the operator and reduces the labor intensity of the workers.

[0034] refer to Figure 2 In one embodiment, the suspension member 12 has a predetermined length along a direction parallel to the axis of the coil in a horizontal position and forms a first assembly portion 121 and a second assembly portion 122, wherein the first assembly portion 121 is on the same side as the coil in a horizontal position, and the second assembly portion 122 is on the opposite side of the coil in a horizontal position. The first assembly portion 121 forms a plurality of the assembly holes 1201 at intervals to facilitate the worker to adjust the connection position between the suspension device and the clamping device for transferring the coil.

[0035] Preferably, the second assembly portion 122 forms a plurality of the assembly holes 1201 at intervals to expand the selection range and improve the practicality of the clamping device for transferring the coil.

[0036] refer to Figure 4 In another embodiment, the suspension member 12 is circular or semi-circular, and the suspension member 12 forms a plurality of mounting holes 1201 at intervals around itself. Since the circumference of the suspension member 12 is greater than its own diameter, the number of mounting holes 1201 can be increased in this embodiment, thereby expanding the selection range and improving the adjustment accuracy.

[0037] In a preferred embodiment, the attitude adjustment mechanism 30 is implemented as a cylinder, the cylinder body is mounted on the high end portion 111 of the mounting body 11, and one end of the piston extending out of the cylinder body is rotatably connected to the clamping mechanism 20.

[0038] It is worth mentioning that the mounting bracket 10 also includes a connecting shaft 13, which is mounted on the lower end 112, and the clamping mechanism 20 is mounted on the connecting shaft 13. The clamping mechanism 20 can rotate relative to the mounting body 11 via the connecting shaft 13.

[0039] In one embodiment, the clamping mechanism 20 includes a connecting body 21 and an outer clamping component 22. The connecting body 21 is connected to the connecting shaft 13 and the attitude adjustment mechanism 30. The outer clamping component 22 includes two opposing outer holding bodies 221 and a belt shifter 222. The belt shifter 222 is mounted on the connecting body 21, and any one of the outer holding bodies 221 is connected to the belt shifter 222. The belt shifter 222 is used to drive any one of the outer holding bodies 221 to move towards or away from the opposing outer holding body 221. The outer holding bodies 221 are located on opposite sides of the outer peripheral wall of the roll to clamp the roll from the outer peripheral wall of the roll.

[0040] By manipulating the mounting body 11, the two outer holding bodies 221 are moved from one end face of the coil to the opposite sides of the outer peripheral wall of the coil, so that the coil is at least partially located between the two outer holding bodies 221. Then, the belt shifter 222 drives any one of the outer holding bodies 221 to move toward the opposite outer holding body 221, so that the two outer holding bodies 221 clamp the coil from the outer peripheral wall of the coil. Subsequently, the mounting body 11 is manipulated to cause the clamping mechanism 20 to move the coil to a designated position.

[0041] In a preferred embodiment, the outer clamping component 22 is provided with two belt shifters 222, and each outer holding body 221 is connected to one of the belt shifters 222. The two belt shifters 222 respectively drive the two outer holding bodies 221 to move closer or further apart from each other.

[0042] As an example, the belt shifter 222 is implemented as a cylinder.

[0043] refer to Figures 3 to 6 Preferably, the outer clamping component 22 further includes a buffer 223, which is installed at one end of the outer holding body 221 away from the belt shifter 222, and the two buffers 223 are disposed opposite to each other. When the outer clamping component 22 clamps the roll material, the buffer 223 is in contact with the outer peripheral wall of the roll material. The flexibility of the buffer 223 is higher than that of the outer holding body 221 to avoid rigid damage to the roll material.

[0044] Preferably, the buffer 223 is made of an elastic material.

[0045] refer to Figure 3 and Figure 6 It is worth mentioning that the two buffer members 223 form an arc surface 22301 on opposite sides. The arc surface 22301 is adapted to the outer peripheral wall of the roll material. The arc surface 22301 provided by the buffer member 223 can increase the contact area with the roll material, avoid stress concentration when the roll material is clamped, and reduce damage to the roll material.

[0046] Preferably, the arc surface 22301 formed by the buffer 223 is provided with anti-slip texture to increase the friction between the arc surface 22301 and the outer peripheral wall of the coil material and improve the stability of clamping.

[0047] Preferably, the outer clamping component 22 further forms a guide rod 224, which is connected to the outer holding body 221. The connecting body 21 forms a guide hole that extends along the distribution direction of the two outer holding bodies 221. The guide rod 224 is inserted into the guide hole formed by the connecting body 21, and the hole wall of the guide hole limits the movement of the outer holding body 221 toward or away from the opposite outer holding body 221.

[0048] Furthermore, the clamping mechanism 20 also includes an inner clamping component 23.

[0049] The inner clamping component 23 includes a insertion post 231, which is connected to the connecting body 21 and located between the two outer holding bodies 221. The insertion post 231 can be inserted into and removed from the insertion channel. The clamping mechanism 20 moves from one end face of the coil towards the coil with the axial direction of the insertion post 231 parallel to the axial direction of the insertion channel and the two outer holding bodies 221 respectively corresponding to opposite sides of the outer peripheral wall of the coil, so that the insertion post 231 can be inserted into the insertion channel.

[0050] Preferably, the insertion post 231 is at least partially in contact with the inner wall of the insertion channel. This increases the contact area between the clamping mechanism 20 and the coil material during clamping, thereby improving the stability of the clamping mechanism 20 in clamping the coil material.

[0051] As a deformable configuration, the inner clamping component 23 further includes a plurality of inner clamping members 232 and a pushing assembly 233. The insertion post 231 forms multiple connecting portions 2311 in its radial direction, and the inner clamping members 232 are pivotally connected to the connecting portions 2311. The inner clamping members 232 are connected to the pushing assembly 233, which drives the inner clamping members 232 to rotate relative to the insertion post 231, so that each inner clamping member 232 at least partially approaches or moves away from the inner wall of the insertion channel to clamp the rolled material from the inner wall of the barrel. Specifically, after the insertion post 231 is inserted into the insertion channel from one end of the rolled material, the pushing assembly 233 drives each inner clamping member 232 at least partially to approach the inner wall of the barrel, such that the inner clamping member 232 abuts against the barrel. After the coil is transferred to the designated position, the pushing assembly 233 drives each of the inner clamping members 232 at least partially away from the inner wall of the barrel, so that the insertion post 231 can be quickly withdrawn from the insertion channel. In this way, the inner clamping members 23 and the outer clamping members 22 simultaneously fix the coil from the outer and inner walls of the coil, respectively, increasing the clamping area of ​​the coil and improving the stability of the coil clamping.

[0052] Preferably, increasing the pressure of the inner clamping component 23 on the inner wall of the material cylinder correspondingly reduces the clamping force of the outer clamping component 22 on the rolled material, thereby reducing the damage of the outer clamping component 22 to the material strip.

[0053] Preferably, the pushing assembly 233 includes a pushing member 2331, a driving member 2332, and an assembly 2333. The driving member 2332 is mounted on the connecting body 21, and the assembly 2333 is mounted on the driving member 2332. The driving member 2332 drives the assembly 2333 to move axially along the insertion post 231. The pushing member 2331 is pivotally connected to the assembly 2333, and the inner clamping member 232 is connected to the pushing member 2331. When the assembly 2333 is driven by the driving member 2332 to move axially along the insertion post 231, the pushing member 2331 drives multiple inner clamping members 232 to pivot simultaneously, such that each inner clamping member 232 at least partially approaches or moves away from the inner wall of the insertion channel to clamp the coiled material from the inner wall of the barrel.

[0054] In one embodiment, the fitting 2333 is sleeved on the insert post 231. The drive member 2332 drives the fitting 2333 to move axially along the insert post 231, causing the pusher member 2331 to push the inner clamping member 232 to pivot.

[0055] In another embodiment, the insertion post 231 forms a hidden channel 23101, the axis of which is parallel to the axis of the insertion channel. The insertion post 231 also forms a plurality of openings 23102 in the circumferential direction that communicate with the hidden channel 23101. Each of the push-rotating members 2331 can extend to the outside through the openings 23102 to push or pull the inner clamping member 232. In this embodiment, the mounting part 2333 and at least a portion of the mounting drive member 2332 are hidden in the hidden channel 23101, which improves the aesthetics of the clamping mechanism 20.

[0056] It is worth mentioning that the inner clamping member 232 has anti-slip texture on the side facing the inner wall of the insertion channel to increase the friction between the inner clamping member 232 and the inner wall of the insertion channel, thereby improving the stability and firmness of the clamping.

[0057] As an example, the drive element 2332 is implemented as a cylinder.

[0058] Preferably, the mounting bracket 10 further includes a handle 14, which is mounted on the mounting body 11. The handle 14 forms two gripping portions 141 to provide a gripping area for the operator, so as to facilitate the operator's overall operation of the clamping device for transferring the coiled material.

[0059] refer to Figures 1 to 2 Furthermore, the clamping device for transferring the coil also includes a control switch assembly 40.

[0060] The control switch assembly 40 includes a first control switch 41. When the attitude adjustment mechanism 30 is implemented as a cylinder, the attitude adjustment mechanism 30 is connected to a pipeline, and a first directional valve is installed on the pipeline. The first control switch 41 is used to control the flow direction and on / off state of the first directional valve to control the operation of the attitude adjustment mechanism 30. The first control switch 41 is mounted on the grip portion 141 to facilitate operation by the operator.

[0061] The control switch assembly 40 includes a second control switch 42. When the conveyor belt 222 is implemented as a cylinder, the conveyor belt 222 is connected to a pipeline, and a second directional valve is provided on the pipeline. The second control switch 42 is used to control the flow direction and on / off state of the second directional valve to control the operation of the conveyor belt 222. The second control switch 42 is mounted on the grip portion 141 to facilitate operation by the operator.

[0062] Preferably, when the drive member 2332 is implemented as a cylinder, the drive member 2332 is connected to a pipe, and a third directional valve is provided on the pipe. The second control switch 42 simultaneously controls the flow direction and on / off state of the third directional valve, so that the second control switch 42 simultaneously controls the operation of the conveyor 222 and the drive member 2332.

[0063] It is worth mentioning that the control switch for controlling the operation of the suspension equipment is located on the grip 141 for operation by the staff.
