Description

[Technical Field]

[0001] This invention relates to the field of pipe processing equipment, and more particularly to a winding device and a multi-station winding device. [Background Technology]

[0002] After rolling, the tubing needs to be stored. The tubing can be stored as straight tubes or wound into coils. To wind the tubing into coils, a winding device is required. A typical winding device includes a frame and multiple winding racks arranged around the center of the frame. During winding, the frame rotates to allow the tubing to wrap around the winding racks, thus forming a coil. However, such a winding device requires a large space during winding and has low safety. To address this, existing technology discloses another winding device, including a frame, rollers, and a bending device. The bending device bends the tubing, which is then gradually conveyed upwards and wound onto the rollers to form a coil. However, this winding device experiences greater wear between the tubing and the rollers. [Summary of the Invention]

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art by proposing a winding device that reduces the damage caused during the winding of tubes.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A winding device includes a winding frame and rotating rollers rotatably mounted on the winding frame for winding tubular material. The winding frame includes a crossbeam, a first frame body disposed at one end of the crossbeam, and a second frame body disposed at the other end of the crossbeam. The first frame body is provided with a bending guide mechanism for bending and guiding the tubular material to wrap around the rotating rollers. The second frame body is provided with a rotating component for driving the rotating rollers to rotate. The winding frame is provided with two rotating rollers, which are disposed on the same horizontal plane. The surface of the rotating rollers is provided with spirally distributed tubular material guide grooves.

[0006] Based on the above scheme, the bending guide mechanism includes a first guide frame protruding from the first frame towards the second frame and a second guide frame disposed outside the first guide frame, and an arc-shaped bending channel for conveying pipe material is defined between the first guide frame and the second guide frame.

[0007] Based on the above scheme, the bending guide mechanism also includes a plurality of rotatable first guide rollers, which are spaced apart along the arc-shaped bending channel. One end of the first guide roller is connected to the side of the first frame near the first guide frame, and the other end of the first guide roller approaches the arc-shaped bending channel.

[0008] Based on the above scheme, the first guide frame includes a plurality of first baffles and a plurality of first transmission rollers arranged at intervals, and the second guide frame includes a plurality of second baffles and a plurality of second transmission rollers arranged at intervals, wherein the first transmission rollers and the second transmission rollers are arranged along the axial direction of the rotating rollers.

[0009] Based on the above scheme, the first frame is provided with a plurality of rotatable second guide rollers, which are arranged transversely to the rotating rollers and are used to support the pipe material after it leaves the arc-shaped bending channel.

[0010] Based on the above scheme, the rotating component includes a drive motor and a sprocket driven by the drive motor. The sprocket is located at one end of the rotating roller that extends out of the second frame, and the sprockets on the two rotating rollers are driven by a chain.

[0011] Based on the above scheme, the first frame is provided with a pipe clamping mechanism on the front side of the bending guide mechanism to guide the pipe material to be conveyed toward the bending guide mechanism. The pipe clamping mechanism includes a clamping frame and a pipe clamping component disposed on the clamping frame for clamping the pipe material.

[0012] Based on the above scheme, the clamping frame is provided with a lifting mechanism connected to the pipe clamping component.

[0013] Based on the above scheme, the second frame is equipped with a sensor for detecting the distance between the pipe and the second frame.

[0014] A multi-station winding device includes a support frame on which multiple winding devices as disclosed in any of the above technical solutions are mounted, and the winding devices are rotatably coupled with the support frame.

[0015] The beneficial effects of this invention are:

[0016] The present invention discloses a winding device for collecting finished tube material. The winding device is typically located behind the equipment used for conveying the tube material. During winding, the tube material is conveyed from the conveying equipment towards the winding device. A bending guide mechanism guides the tube material towards the rotating roller and gradually bends it during conveying, allowing it to wind onto the rotating roller. A rotating component drives the rotating roller to rotate, making it easier for the tube material to wind onto the roller and reducing relative friction between the roller and the tube material, thus preventing wear on the surfaces of both.

[0017] As the number of windings on the rotating roller increases, once the number of windings reaches a certain level, the power of the conveying device to drive the pipe becomes insufficient, causing the pipe to be unable to continue winding onto the rotating roller. Meanwhile, the pipe behind continues to be conveyed forward, causing the pipe to bend. The rotating component can provide additional power, using the friction between the rotating roller and the pipe to drive the pipe to be conveyed, ensuring that the pipe can be smoothly wound onto the rotating roller.

[0018] The tube guide grooves on the surface of the rotating roller guide the tube, allowing it to move gradually along the axial direction of the rotating roller while rotating circumferentially. This reduces wear caused by the tube moving axially along the rotating roller, and also maintains a certain distance between tubes in adjacent guide grooves to prevent them from squeezing each other.

[0019] By incorporating two rotating rollers, the support for the pipe is improved. The weight of the pipe is distributed across the two rollers, reducing the pressure on the contact surface between the pipe and the rollers, thus providing better protection for the pipe. Furthermore, the ability of both rollers to rotate enhances the smoothness of pipe transmission. Positioning the two rollers on the same horizontal plane further improves the support for the pipe, ensuring its weight is evenly distributed across them.

[0020] Furthermore, the bending guiding mechanism includes a first guide frame protruding from the first frame towards the second frame and a second guide frame disposed outside the first guide frame. The first guide frame and the second guide frame define an arc-shaped bending channel for conveying the tubing. When the tubing is conveyed to the bending guiding mechanism, it contacts the protruding first or second guide frame, causing the tubing to be blocked and unable to continue being conveyed horizontally. Instead, it is conveyed along the arc-shaped bending channel. As the tubing continuously enters the arc-shaped bending channel, it gradually bends, allowing it to wrap around the rotating roller after leaving the arc-shaped bending channel.

[0021] Furthermore, the bending guiding mechanism also includes multiple rotatable first guide rollers, which are spaced apart along the arc-shaped bending channel. One end of each first guide roller is connected to the side of the first frame near the first guide frame, and the other end of each first guide roller approaches the arc-shaped bending channel. During the winding process on the rotating rollers, the tubing continuously moves axially along the tubing, thus leaving the arc-shaped bending channel. The first guide rollers can block the tubing, limiting its deviation from the arc-shaped bending channel towards the side of the first frame near the first guide frame, preventing the inner diameter of the wound material from being too small. The first guide rollers can rotate under the influence of the tubing, reducing wear on the tubing.

[0022] Furthermore, the first guide frame includes a plurality of first baffles and a plurality of first drive rollers spaced apart, and the second guide frame includes a plurality of second baffles and a plurality of second drive rollers spaced apart. The first drive rollers and the second drive rollers are arranged along the axial direction of the rotating rollers. The first baffles and the second baffles can block the tube material and keep it within the arc-shaped bending channel, so that the tube material gradually bends during the conveying process. The first drive rollers and the second drive rollers can contact the tube material and rotate during the conveying of the tube material along the arc-shaped bending channel, reducing the wear of the tube material within the arc-shaped bending channel and improving the smoothness of the tube material's conveying within the arc-shaped bending channel.

[0023] Furthermore, the first frame is equipped with multiple rotatable second guide rollers, which are arranged transversely to the rotating rollers. These second guide rollers support the pipe material after it leaves the arc-shaped bending channel. Since the pipe material has already been bent after passing through the arc-shaped bending channel, it is not necessary to arrange bending guide mechanisms on the entire first frame. The second guide rollers prevent direct contact between the pipe material and the first frame, and their rotation, driven by the pipe material, reduces wear on the pipe material.

[0024] Furthermore, the rotating component includes a drive motor and a sprocket driven by the drive motor. The sprocket is located at the end of the rotating roller that extends out of the second frame. The sprockets on the two rotating rollers are driven by a chain. The sprocket is located outside the second frame to prevent the pipe material from contacting the sprocket and affecting the transmission between the rotating component and the rotating roller, and also to prevent the pipe material from being damaged by the rotating component. Power is transmitted through a chain and sprocket, which avoids slippage.

[0025] Furthermore, the first frame is equipped with a tube clamping mechanism located in front of the bending guide mechanism to guide the tube material towards the bending guide mechanism. The tube clamping mechanism includes a clamping frame and tube clamping components disposed on the clamping frame for clamping the tube material. Because tube material is easily deformed, the end of the tube material will deviate downwards after leaving the conveying equipment and may not align with the bending guide mechanism. The tube clamping mechanism uses the tube clamping components to clamp the tube material and limit its deviation, ensuring the smooth progress of the winding process. This step also eliminates the need for manual operation, reducing the investment of human resources.

[0026] Furthermore, the clamping frame is equipped with a lifting mechanism connected to the pipe clamping component. The lifting mechanism can control the pipe clamping component to move up and down. When the pipe clamping component clamps the pipe, the lifting mechanism can control the position of the pipe clamping component to align the pipe clamping component with the pipe, and after clamping the pipe, it can lift the pipe clamping component to align the end of the pipe with the bending guide mechanism.

[0027] Furthermore, the second frame is equipped with a sensor for detecting the distance between the tube and the second frame. Under the action of the sensor, the number of tube turns on the rotating roller can be determined. Once the distance between the tube and the second frame reaches the set range, the tube feeding will stop to avoid excessive tube turns on the rotating roller, which would cause the tube to be squeezed and deformed.

[0028] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and accompanying drawings. [Attached Image Description]

Detailed Implementation Methods

[0040] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present invention.

[0041] The terms "exemplary" and "some embodiments" used below are meant to be "used as examples, embodiments, or illustrations," and any embodiment described as "exemplary" is not necessarily to be construed as superior to or better than other embodiments. Numerous specific details are set forth in the following detailed description to better illustrate the invention, and those skilled in the art will understand that this disclosure can be practiced without certain specific details.

[0042] Reference Figures 1 to 3 This invention discloses a winding device, including a winding frame 100 and a rotating roller 200 rotatably mounted on the winding frame 100 for winding tube material. The winding frame 100 includes a crossbeam 110, a first frame 120 disposed at one end of the crossbeam 110, and a second frame 130 disposed at the other end of the crossbeam 110. The first frame 120 is provided with a bending guide mechanism for bending and guiding the tube material to wrap around the rotating roller 200. The second frame 130 is provided with a rotating component for driving the rotating roller 200 to rotate. The winding frame 100 is provided with two rotating rollers 200, which are disposed on the same horizontal plane. The surface of the rotating roller 200 is provided with spirally distributed tube material guide grooves 210.

[0043] The winding device is used to collect the finished tube material. It is typically located behind the equipment used for conveying the tube material. During winding, the tube material is fed from the conveying equipment towards the winding device. A bending guide mechanism guides the tube material towards the rotating roller 200, gradually bending it during transport so that it can be wound onto the rotating roller 200. A rotating component drives the rotating roller 200 to rotate, making it easier for the tube material to wind onto it and reducing relative friction between the roller 200 and the tube material, thus minimizing wear on their surfaces.

[0044] As the number of windings on the rotating roller 200 increases, when the number of windings increases to a certain extent, the power of the conveying device to drive the pipe is insufficient, which will cause the pipe to be unable to continue winding on the rotating roller 200. Meanwhile, the pipe behind is still being conveyed forward, which will cause the pipe to bend. The rotating component can provide additional power and drive the pipe to be conveyed through the friction between the rotating roller 200 and the pipe, so as to ensure that the pipe can be smoothly wound on the rotating roller 200.

[0045] The tube guide groove 210 on the surface of the rotating roller 200 guides the tube, so that the tube moves gradually along the axial direction of the rotating roller 200 while rotating circumferentially, thereby reducing the wear caused by the tube moving along the axial direction of the rotating roller 200. At the same time, the tubes in adjacent guide grooves can also maintain a certain distance to avoid mutual squeezing between the tubes.

[0046] By incorporating two rotating rollers 200, the support effect on the pipe material is improved. The weight of the pipe material can be distributed across the two rotating rollers 200, reducing the pressure on the contact surface between the pipe material and the rollers 200, thus providing better protection for the pipe material. Furthermore, the ability of both rotating rollers 200 to rotate enhances the smoothness of pipe material transmission. The fact that the two rotating rollers 200 are positioned on the same horizontal plane further improves the support effect on the pipe material, allowing its weight to be evenly distributed across them.

[0047] A rotating roller 200 is positioned at the upper end of the first frame 120, and a bending guide mechanism is positioned at the lower end of the first frame 120, enabling the tube to bend during upward conveying. Specifically, the bending guide mechanism includes a first guide frame 140 protruding from the first frame 120 toward the second frame 130 and a second guide frame 150 positioned outside the first guide frame 140. The first guide frame 140 and the second guide frame 150 define an arc-shaped bending channel 160 for tube conveying. When the tube is conveyed to the bending guide mechanism, it contacts the protruding first guide frame 140 or second guide frame 150, causing the tube to be blocked and unable to continue horizontally conveyed, instead being conveyed along the arc-shaped bending channel 160. As the tube continuously enters the arc-shaped bending channel 160, it gradually bends, allowing it to wrap around the rotating roller 200 after leaving the arc-shaped bending channel 160.

[0048] To reduce wear on the tube during bending, the first guide frame 140 includes a plurality of first baffles 141 and a plurality of first drive rollers 142 spaced apart, and the second guide frame 150 includes a plurality of second baffles 151 and a plurality of second drive rollers 152 spaced apart. The first drive rollers 142 and the second drive rollers 152 are arranged along the axial direction of the rotating roller 200. The first baffles 141 and the second baffles 151 can block the tube and keep it within the arc-shaped bending channel 160, so that the tube gradually bends during the conveying process. The first drive rollers 142 and the second drive rollers 152 can contact the tube and rotate during the conveying of the tube along the arc-shaped bending channel 160, thereby reducing wear on the tube within the arc-shaped bending channel 160 and improving the smoothness of the tube's conveying in the arc-shaped bending channel 160.

[0049] The arc-shaped bending channel 160 has a limited depth. During the winding process on the rotating roller 200, the tube material will continuously move along the axial direction of the tube material, thereby leaving the arc-shaped bending channel 160. The bending guiding mechanism also includes multiple rotatable first guide rollers 170. The multiple first guide rollers 170 are arranged at intervals along the arc-shaped bending channel 160. One end of the first guide roller 170 is connected to the side of the first frame 120 near the first guide frame 140, and the other end of the first guide roller 170 approaches the arc-shaped bending channel 160. The first guide roller 170 can block the tube material and limit the tube material from deviating from the arc-shaped bending channel 160 to the side of the first frame 120 near the first guide frame 140, resulting in the inner diameter of the wound material being too small after winding. The first guide roller 170 can rotate under the drive of the tube material to reduce the wear on the tube material.

[0050] As the tubing is conveyed, it leaves the curved bending channel 160 and approaches the rotating roller 200. At this point, the tubing has already been bent, so it is not necessary to arrange bending guide mechanisms on the entire first frame 120. The first frame 120 is provided with multiple rotatable second guide rollers 180. The second guide rollers 180 are arranged transversely to the rotating roller 200. The second guide rollers 180 are used to support the tubing after it leaves the curved bending channel 160, which can prevent the tubing from directly contacting the first frame 120. At the same time, the second guide rollers 180 can rotate under the drive of the tubing, reducing the wear of the tubing.

[0051] The tubing needs to enter the curved bending channel 160 before it can be bent. However, the opening of the curved bending channel 160 is fixed. The tubing is soft and easily deformed during rolling, and the end of the tubing deviates downwards after leaving the conveying equipment, making it impossible to align with the bending guide mechanism. A tubing clamping mechanism is located on the first frame 120, in front of the opening of the curved bending channel 160, to guide the tubing towards the bending guide mechanism. The tubing clamping mechanism includes a clamping frame 300 and tubing clamping parts 310 disposed on the clamping frame 300 for clamping the tubing. The tubing clamping mechanism uses the tubing clamping parts 310 to clamp the tubing, limiting its deviation and ensuring smooth winding. This step also eliminates manual operation, reducing manpower input.

[0052] Considering factors such as the size and material of the pipe, the deviation of the pipe produced under different production conditions varies. The clamping frame 300 is also equipped with a lifting mechanism 320 connected to the pipe clamping member 310. The lifting mechanism 320 can control the lifting movement of the pipe clamping member 310. When the pipe clamping member 310 clamps the pipe, the lifting mechanism 320 can control the position of the pipe clamping member 310 to align the pipe clamping member 310 with the pipe, and after clamping the pipe, lift the pipe clamping member 310 to align the end of the pipe with the bending guide mechanism.

[0053] The amount of tube material that the rotating roller 200 can carry is limited. When the amount of tube material on the rotating roller 200 reaches the rated amount, the continued conveying of the tube material will cause the number of tube material turns on the rotating roller 200 to be too many, which will cause the tube material to be squeezed against each other and deform. The second frame 130 is equipped with a sensor for detecting the distance between the tube material and the second frame 130. Under the action of the sensor, the number of tube material turns on the rotating roller 200 can be determined. Once the distance between the tube material and the second frame 130 reaches the set range, the tube material will be stopped from being collected.

[0054] The rotating component mentioned above includes a drive motor 400 and a sprocket 410 driven by the drive motor 400. One end of the rotating roller 200 extends out of the second frame 130. The sprocket 410 is located at the end of the rotating roller 200 that extends out of the second frame 130 to prevent the pipe material from contacting the sprocket 410 and affecting the transmission between the rotating component and the rotating roller 200. It also prevents the pipe material from being damaged by the rotating component. The sprockets 410 on the two rotating rollers 200 are driven by chains. The rotating component also includes two gears mounted on the drive shaft of the drive motor 400. One gear is driven by one of the sprockets 410 through a chain 420, and the other gear is driven by the other sprocket 410 through a chain 420. Power is transmitted through the chain 420 and the sprocket 410, which can prevent slippage.

[0055] Reference Figure 4 The present invention also discloses a multi-station winding device, including a support frame 500. The support frame 500 is provided with a plurality of winding devices disclosed in any of the above technical solutions. The winding devices are rotatably coupled with the support frame 500 so that they can move in the circumferential direction of the support frame 500. In this way, when one winding device completes the winding of the tube, it can rotate along the support frame 500 and leave the conveying equipment for subsequent processing. Another winding device moves to the winding position to continue winding the tube. This can reduce the interval time between two tube rolling processes and improve the operation efficiency.

[0056] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the present invention will be included within the scope of the claims.
