A pipe winding device

Abstract

This invention relates to a pipe winding device, including a winding arm clamping assembly. The winding arm clamping assembly includes a support arm, a clamping plate movably mounted on the support arm, and a first driver for driving the clamping plate. One end of the support arm is rotatably mounted on a movable plate. The output end of the first driver is connected to the clamping plate, and the clamping plate is connected to the other end of the support arm. When the first driver drives the clamping plate to extend outward from the support arm, the support arm rotates on the movable plate along with the movement of the clamping plate. The support arm is inclined on the movable plate and forms an unloading arm inclined below the movable plate. After winding and packaging, the pipe is pushed outward from the support arm along the inclined unloading arm. Only a small pushing force is needed to push the wound and packaged pipe out of the support arm. This solves the technical problem that the existing support arm is in a horizontal state when unwinding the pipe, making it difficult to push the pipe out of the support arm, and causing the pipe surface to be scratched due to excessive friction.

Description

Technical Field

[0001] This invention relates to the technical field of plastic pipe winding, specifically a pipe winding device. Background Technology

[0002] Existing pipe coiling clamps include an arm for supporting the pipe and a clamp plate that is horizontally openable or vertically retractable on the arm. The clamp plate is movably mounted at one end of the arm. During pipe coiling, the clamp plate is vertical on the arm, and an adjustment plate is located at the other end of the arm. The adjustment plate is slidably mounted on the arm, and the distance between the adjustment plate and the clamp plate is adjusted by moving the adjustment plate, thereby coiling the pipe into coils of different thicknesses. After the pipe is coiled and bundled, it needs to be pushed out of the arm. At this time, the clamp plate needs to open horizontally, and the horizontal opening of the clamp plate does not prevent the pipe from coming out of the arm. The support surface of the boom that supports the pipe is in a horizontal state. However, the pipe is heavy and the friction of the pipe sliding on the boom is large, making it difficult for the pipe to come out of the boom, as in the winding machine clamps disclosed in Chinese patent numbers ZL201720239845.5, ZL201922202467.5, and ZL202211226731.9.

[0003] In addition, the pipe is supported on a winding arm for winding, and the pipe is guided onto the winding arm by guide wheels, as in the pipe winding machine disclosed in Chinese Patent No. ZL201821717109.7, see the accompanying drawings in the specification of that patent document. Figure 1 The winding machine has several guide wheels on the frame above the winding arm. The pipe is fed to the winding arm along the guide wheels. The winding machine rotates and winds up the pipe. The pipe passes through the guide wheels. The pipe is easily pulled to the winding arm of the winding machine by the rolling of the guide wheels. This has the defect of easily scratching the outer surface of the pipe.

[0004] Therefore, further improvements are needed. Summary of the Invention

[0005] The purpose of this invention is to provide a pipe winding device. After the pipe is wound and packaged, it is pushed outward from the support arm along the inclined unloading arm. Only a small pushing force is needed to push the wound and packaged pipe out of the support arm, solving the technical problem that the existing support arm is in a horizontal state when the pipe is unwound, making it difficult to push the pipe out of the support arm, and causing the pipe surface to be scratched due to excessive friction. The clamping block is close to or away from the clamping plate, thereby clamping or releasing the inner wall of the pipe. The structure of pushing the pipe with guide wheels is eliminated, and the pipe is directly pushed to the winding arm (the pipe can be transported by pushing through a linear guide rail or linear slider. The linear slider is equipped with a support for the pipe, and the support directly drives the pipe to push to the winding arm when sliding). When the pipe is pushed into place, the clamping block clamps the inner wall of the pipe under the drive of the second driver, effectively replacing the use of guide wheels to push the pipe and solving the technical problem that the use of guide wheels may cause surface scratches on the pipe.

[0006] The objective of this invention is achieved as follows:

[0007] A pipe winding device includes several winding arm clamping assemblies arranged on a turntable. Each winding arm clamping assembly includes a support arm for supporting the pipe, a clamping plate movable on the support arm, and a first driver for driving the clamping plate to move. One end of the support arm is rotatably mounted on the movable plate. The output end of the first driver is connected to the clamping plate, and the clamping plate is connected to the other end of the support arm.

[0008] When the first driver drives the clamping plate to extend outward to the support arm, the support arm rotates on the movable plate as the clamping plate moves. The support arm tilts on the movable plate and forms an unloading arm that tilts downward along the movable plate. After the tube is wound and packaged, it comes out of the support arm along the tilted unloading arm. Only a small pushing force is needed to push the wound and packaged tube out of the support arm. This solves the technical problem that the existing support arm is in a horizontal state when the tube is unwound and it is difficult to push the tube out of the support arm. It also causes the tube surface to be scratched due to excessive friction.

[0009] The clamping plate is equipped with a movable clamping block and a second driver that drives the clamping block to move. The output end of the second driver is connected to the clamping block. The second driver drives the clamping block to move towards one side of the clamping plate, so that the clamping block is closer to or away from the clamping plate, thereby clamping or loosening the inner wall of the pipe. This eliminates the structure of using guide wheels to push the pipe, and pushes the pipe directly to the winding arm (the pipe can be transported by a linear guide rail or linear slider. The linear slider is equipped with a support for the pipe, and the support directly drives the pipe to push towards the winding arm when it slides). When the pipe is pushed into place, the clamping block clamps the inner wall of the pipe under the drive of the second driver, effectively replacing the use of guide wheels to push the pipe and solving the technical problem that guide wheel pushing may cause surface scratches on the pipe.

[0010] A connecting plate is provided between one end of the support arm and the movable plate. One end of the connecting plate is hinged to the movable plate, and the other end of the connecting plate is connected to the support arm. The support arm is rotatably mounted on the movable plate through the connecting plate.

[0011] A rotation clearance is provided between the movable plate and the connecting plate. When the clamping plate extends outward to the support arm, the connecting plate drives the support arm to rotate on the movable plate through the rotation clearance, thereby forming an inclined unloading arm. The rotation clearance between the movable plate and the connecting plate allows the support arm to have a rotational clearance when the clamping plate extends outward, causing the support arm to tilt.

[0012] The connecting plate has an inclined surface, which forms a rotation clearance between the connecting plate and the movable plate. When the clamping plate extends to the outer end of the support arm, the support arm and the connecting plate move and rotate on the movable plate with the movement of the clamping plate. The inclined surface of the connecting plate abuts against the movable plate to form a support point for the inclined support arm, making the structure stable.

[0013] There is a rotation clearance between the movable plate and the connecting plate. The distance between the rotation clearances is L. The distance L gradually decreases along the top of the movable plate. When the clamping plate extends to the outer end of the support arm, the distance L of the rotation clearances gradually decreases along the top of the movable plate. This allows the support arm to rotate downwards towards the movable plate.

[0014] The connecting plate is provided with a limiting component, and the support arm is provided with a supporting surface for supporting the support material. The support arm has a first position state and a second position state.

[0015] When the first driver drives the clamping plate to retract towards the support arm, the support arm is in the first position and the support surface of the support arm is in a horizontal position, which facilitates the winding of the pipe.

[0016] When the first driver drives the clamping plate to extend out of the support arm, the support arm is in the second position and the support surface of the support arm is in an inclined state, forming a stripping slope. After the pipe is wound, packaged and bundled, it is stripped out of the support arm through the stripping slope. The stripping slope has low frictional resistance, which can effectively prevent scratches on the surface of the pipe.

[0017] When the support arm switches from the second position to the first position, the limiting member abuts against the movable plate to limit the rotation of the connecting plate;

[0018] The limiting component is rotatably telescopically mounted on the connecting plate. By rotating the limiting component, the telescopic length of one end of the limiting component on the connecting plate can be adjusted, thereby adjusting the position of the connecting plate's rotation limit.

[0019] Each retractor clamping assembly has a movable plate that slides back and forth on a turntable. The turntable is equipped with a bevel gear. Each retractor clamping assembly has a movable nut on its movable plate. Each movable plate has a rotating screw that passes through the movable nut. One end of each rotating screw is equipped with a transmission gear that meshes with the bevel gear.

[0020] When the rotating screw on the movable plate of one of the winding arm clamping assemblies rotates, the movable nut of the movable plate moves along the corresponding rotating screw to adjust the spacing between several winding arm clamping assemblies on the turntable, thereby adjusting the diameter of the coil during the forming of the winding tube. When the rotating screw of one of the movable plates rotates, it drives the rotating screws of the other movable plates to rotate simultaneously through the transmission gear and the bevel gear, so that the movable plates of each winding arm clamping assembly move synchronously on the turntable.

[0021] The turntable has a rotating shaft, a detection element on the rotating shaft, several detection positions on the detection element, a detector below the detection position, and an identification device equipped with the detector. The detector and the identification device are electrically connected. The rotation angle position information of the rotating shaft is transmitted to the identification device through the detection position and the detection element, so that the identification device can identify the rotation angle position of the rotating shaft.

[0022] The detector is a photoelectric or magnetically controlled detector, and the number of detection positions corresponds to the number of winding arm clamping components. It can be used in conjunction with structures that package or clamp the inner wall of pipes. When packaging pipes, the detector identifies the rotation angle of the turntable, rotates it once, and then performs the bundling. For example, if there are six winding arm clamping components, the turntable rotates 60° each time. When the turntable reaches the corresponding position, the detector identifies the position, the turntable stops rotating, and then the bundling begins. After bundling is completed, the turntable rotates another 60° until it completes one full rotation and the pipe bundling is finished.

[0023] The support arm is also equipped with an adjusting plate that slides back and forth on the support arm. The support arm has an adjusting groove, the adjusting plate has a positioning block, and a locking block is located on one side of the adjusting groove. A locking element is provided between the positioning block and the locking block. When the adjusting plate moves, the locking element releases the locking element from the positioning block and the locking block, and the adjusting plate slides back and forth on the support arm along the adjusting groove. After adjustment, the adjusting plate locks the positioning block to the locking block through the locking element, thereby locking and fixing the adjusted plate to the support arm and realizing the adjustment of the thickness of the coiled pipe.

[0024] The beneficial effects of this invention are as follows:

[0025] After the tube is wound and packaged, it is pushed outward from the support arm along the inclined unloading arm. Only a small pushing force is needed to push the wound and packaged tube out of the support arm, solving the technical problem that the existing support arm is in a horizontal position when the tube is unwound, making it difficult to push the tube out of the support arm and causing the tube surface to be scratched due to excessive friction. The clamping block is close to or away from the clamping plate, thereby clamping or releasing the inner wall of the tube. The structure of pushing the tube with guide wheels is eliminated, and the tube is directly pushed to the winding arm (the tube can be transported by pushing through linear guide rails and linear sliders. The linear slider has a support for the tube, and the support directly pushes the tube to the winding arm when sliding). When the tube is pushed into place, the clamping block clamps the inner wall of the tube under the drive of the second driver, effectively replacing the technical problem of pushing the tube with guide wheels and solving the technical problem of surface scratches caused by the guide wheel pushing.

[0037] When the first driver 5 drives the clamping plate 4 to extend to the outer end of the support arm 3, the support arm 3 rotates on the movable plate 6 with the movement of the clamping plate 4. The support arm 3 tilts on the movable plate 6 and forms a discharge arm that tilts along the lower part of the movable plate 6.

The other part of the connecting plate 9 is limited and installed between the two limiting blocks, and the connecting plate 9 and the two limiting blocks are connected by a rotating shaft so that the connecting plate 9 is rotatably mounted on the movable plate 6.

[0044] A rotation clearance 10 is provided between the movable plate 6 and the connecting plate 9. When the clamping plate 4 extends to the outer end of the support arm 3, the connecting plate 9 drives the support arm 3 to rotate on the movable plate 6 through the rotation clearance 10, so as to realize that the support arm 3 forms an inclined unloading arm.

[0045] The connecting plate 9 is provided with an inclined surface 11. The connecting plate 9 forms a rotation clearance 10 with the movable plate 6 through the inclined surface 11.

[0049] When the first driver 5 drives the clamping plate 4 to extend out of the support arm 3, the support arm 3 is in the second position state, and the support surface 14 of the support arm 3 is in an inclined state, forming a material removal slope.

[0050] When the support arm 3 switches from the second position state to the first position state, the limiting member 12 abuts against the movable plate 6 to form a rotation limit for the connecting plate 9;

[0051] The limiting member 12 is rotatably telescopically mounted on the connecting plate 9. By rotating the limiting member 12, the telescopic length of one end of the limiting member 12 on the connecting plate 9 can be adjusted, thereby adjusting the position of the connecting plate 9 to rotate and limit.
