[0043] In order to explain in detail the technical content, structural features, objectives and effects of the present application, the technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0044] In this application, spatially relative terms such as "under", "below", "under", "lower", "above", "upper", "above", "higher", "side" (for example, as in "sidewall"), etc., are used to describe the relationship of one element to another (other) element as shown in the accompanying drawings. The spatially relative terms are intended to include different orientations of the device in use, operation and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the accompanying drawings is turned over, the elements described as "under" or "beneath" other elements or features will then be positioned as "above" the other elements or features. Therefore, the exemplary term "under" can include both above and below orientations. In addition, the device can be positioned otherwise (for example, rotated 90 degrees or at other orientations), so the spatially relative descriptors used herein are interpreted accordingly.

[0045] Figure 1 The pipe winding device 100 provided by the present application is shown, which can realize the entire process of automatic pipe winding, winding, bundling and unloading, so as to replace the existing manual winding method and improve the production efficiency of the pipe production line. Specifically, the pipe winding device 100 includes a pipe winding machine 10 that can realize automatic winding, a pipe winding machine 20 that winds the pipe into a pipe coil, a pipe bundling machine 30 for bundling the pipe coil, and a pipe unloading machine 40 that unloads the bundled pipe coil.

[0046] For ease of explanation, in this application, "tube coil" means the tube that is rolled into a coil. The "tube coil" is defined by an axial centerline and forms a multi-layer structure along its radial direction, and the tubes on each layer are arranged roughly along the axial direction; "coiling position" means the initial position of the tube from the tube coiler 10 being rolled onto the tube coil, which includes the position in the axial direction and the position in the radial direction of the tube coil; "coiling angle" means the angle formed by the tube coming out of the tube coiler 10 relative to the radial direction at the coiling position. In this application, the ideal coiling angle is the tangent angle corresponding to the coiling position. It should be noted that the above-mentioned "coiling position" and "coiling angle" are only used to illustrate the working principles and technical effects of some components on the tube winding device 100, and are not limitations on the structure or function of the components.

[0047] In addition, the present application defines the axis direction of the turntable 22 (see below) mounted on the tube winding machine 20 as the first direction (eg Figure 5 The viewing direction of the first direction is defined as the horizontal direction perpendicular to the first direction as the second direction (e.g. Figure 5 It can be understood that the axis of the tube coil mounted on the tube coiler 20 coincides with the axis of the turntable 22. In the present application, "upstream" and "downstream" respectively mean that one component is located upstream or downstream of another component in terms of the moving direction of the tube.

[0048] See also Figure 2 , which shows the pipe coiling machine 10 provided by the present application, which can adjust the pipe coiling position along the first direction and adjust the pipe coiling angle following the change of the radial length of the pipe coil. Specifically, the pipe coiling machine 10 includes a carrying platform (not shown in the figure) for supporting, guiding and conveying the pipe and a supporting base (not shown in the figure) supporting the carrying platform. Among them, the supporting base includes a supporting mechanism (not shown in the figure) that can carry the pipe to move along the first direction and an angle adjustment mechanism (not shown in the figure) that can adjust the pipe coiling angle.

[0049] Combination Figure 3-4 The carrying platform defines a tube path for the tube to move toward the tube winding machine 20 and includes a support plate 11 for supporting various functional components, wherein the various functional components include a guide component arranged in sequence from upstream to downstream, a tube feeding component for conveying the tube, a tube cutting component for cutting the tube, and a guide tube component for guiding the tube into winding.

[0050] The guide assembly includes a limit frame 12A with a through opening, a guide member 12B located upstream of the limit frame 12A, and a guide cylinder 12C for driving the guide member 12B to rotate. The limit frame 12A is fixed on the support plate 11, and the pipe path passes through the through opening on it to position the pipe. The front end of the guide member 12B is supported on the support plate 11 via a rotating shaft 12D so as to be rotatable in the vertical direction, and the rear end of the guide member 12B has a vertical stopper extending in the up-down direction for contacting the pipe in the side. The guide member 12B has a first position (see Figure 3 ) and the second position (see Figure 4 ), when the guide member 12B is in the first position, the vertical blocking rod does not contact the pipe to maintain the original transmission direction of the pipe. At this time, the pipe is on the straight extension line from the limit frame 12A to the cutter positioning port. When the guide member 12B is in the second position, the vertical blocking rod contacts the pipe to force the pipe to produce a certain deflection. The guide cylinder 12C has a cylinder body (not shown in the figure) rotatably connected to the limit frame 12A and a cylinder shaft (not shown in the figure) that can be extended relative to the cylinder body. The end of the cylinder shaft away from the cylinder body is transmission-connected to the end of the rotating shaft 12D. Thus, the guide cylinder 12C can drive the guide member 12B to switch between the first and second positions. In other embodiments, power components such as motors, oil pumps, and electromagnetic actuators can also be used to replace the guide cylinder 12C of this embodiment.

[0051] When the pipe winding device 100 is in the winding or rewinding stage, the guide member 12B is located at the first position to avoid causing movement resistance to the pipe; when the pipe winding device 100 is in the bundling or unloading stage, the guide member 12B is located at the second position to make the pipe have a certain deflection. Therefore, during the period when the pipe winding device 100 is suspended from rewinding, the pipe produced upstream can be temporarily stored on the ground between the pipe winding machine 10 and the upstream equipment.

[0052] The pipe delivery assembly includes a wheel seat 13A fixed on the support plate 11, a driving motor 13B that provides power for moving the pipe, a driving wheel 13C that is transmission-connected to the driving motor 13B, a driven wheel 13D that matches the driving wheel 13C, and a lifting cylinder 13E that is used to drive the driven wheel 13D to move up and down. The driving wheel 13C is rotatably supported on the wheel seat 13A, and the driven wheel 13D is rotatably supported on the bottom of the lifting cylinder 13E. The lifting cylinder 13E is fixedly connected to the top of the wheel seat 13A, and it can drive the driven wheel 13D to move up and down or generate a force to compress the pipe. In this embodiment, the driving wheel 13C and the driven wheel 13D are arranged opposite to each other up and down and are both arranged inside the wheel seat 13A, and the pipe path passes between the driving wheel 13C and the driven wheel 13D.

[0053] When the pipe coiling machine 10 transports the pipe downstream, the driving wheel 13C and the driven wheel 13D clamp the pipe from the upper and lower sides respectively, and the driving motor 13B drives the driving wheel 13C to rotate, thereby transporting the pipe downstream; when the pipe coiling machine 10 needs to brake the pipe, the driving motor 13B stops rotating, and the lifting cylinder 13E drives the driven wheel 13D to move downward, so that the driven wheel 13D presses the pipe with greater pressure, thereby achieving a braking effect.

[0054] Furthermore, the pipe coiling machine 10 is also equipped with a metering assembly for measuring the length of the conveyed pipe, and the metering assembly includes a meter wheel 14A disposed upstream of the pipe conveying assembly and a counter 14 (not shown in the figure) for measuring the number of revolutions of the meter wheel 14. The meter wheel 14 is located near the pipe and can be rotated by the pipe, and the counter signal is connected to the control center (not shown in the figure) of the pipe winding device 100, thereby obtaining the length of the conveyed pipe.

[0055] The pipe cutting assembly includes a cutter seat 15A fixedly mounted on the support plate 11, a cutter 15B escalably arranged on the cutter seat 15A, and a cutter cylinder 15C fixedly mounted on the top of the cutter seat 15A. The cutter seat 15A defines a positioning opening on the pipe path, and the positioning opening is also located on the moving path of the cutter 15C. The cutter cylinder 15C is connected to the cutter 15B in a transmission manner and is configured to drive the cutter 15A to insert and withdraw from the positioning opening. Thus, the hose can be selectively cut from the positioning opening.

[0056] The guide tube assembly includes a guide tube 16A whose inner diameter is slightly larger than the outer diameter of the pipe, a guide tube frame 16B for supporting the guide tube 16A, a telescopic rod 16C telescopically mounted on the support plate 11, and a guide tube cylinder 16D for driving the guide tube 16A to move back and forth. The guide tube 16A defines an inner cavity for the pipe to pass through and has a third position (such as Figure 1 ) and a fourth position (eg, Figure 2 ), its third position is used to accurately guide the pipe to be wound on the pipe reel from a preset winding angle and winding position, and its fourth position facilitates the pipe to pass through the guide pipe 16A along the pipe path.

[0057] Specifically, the end of the telescopic rod 16C protruding from the support plate 11 is fixedly connected to the guide tube frame 16B, so that the guide tube frame 16B can drive the guide tube 16A to move. The guide tube cylinder 16D has a cylinder body fixed on the support plate 11 and a cylinder shaft that can be telescopic relative to the cylinder body. The end of the cylinder shaft away from the cylinder body is fixedly connected to the guide tube frame 16B to drive the guide tube to move back and forth between the third and fourth positions. Similarly, in other embodiments, power components such as motors, oil pumps, and electromagnetic actuators can also be used to replace the guide tube cylinder 16D of this embodiment.

[0058] The supporting mechanism for supporting the mounting platform includes a pair of fixed rails 17A extending approximately along the second direction, a pair of slide rails 17B mounted on the pair of fixed rails 17A, a movable seat 17C movable along the pair of slide rails 17B, and a plurality of power components for realizing the movement of the movable seat 17C.

[0059] A pair of fixed rails 17A are arranged opposite to each other along a first direction, and both ends of each fixed rail 17A are firmly fixed to the ground by anchor bolts. Both ends of a pair of slide rails 17B are respectively fixed to the fixed rails 17A on the corresponding side, and the top of each slide rail 17B is constructed as an I-shaped slide groove, and the bottom of the movable seat 17C cooperates with the above-mentioned I-shaped slide groove to achieve sliding on the pair of slide rails 17B.

[0060] The power components for realizing the movement of the movable seat 17C along the first direction include a servo motor 17D, a reduction box 17E and a ball screw transmission assembly. The ball screw transmission assembly mainly includes a screw rod 17F, a movable nut 17G that forms a threaded fit with the screw rod 17F, and a ball (not shown in the figure) located at the fitting position of the screw rod 17F and the movable nut 17G. The screw rod 17F can be rotatably installed on a pair of fixed rails 17A along an axis extending in the first direction, and the movable nut 17G is fixedly connected to the bottom of the movable seat 17C. The servo motor 17D, the reduction box 17E and the screw rod 17F are sequentially connected in transmission, so that the servo motor 17D drives the screw rod 17F to rotate, thereby driving the nut 17G to move along the first direction, and then driving the movable seat 17C to move along the first direction.

[0061] The moving component is used to adjust the coiling position of the pipe in the axial direction when the pipe is rolled up, so that the pipe can be laid flat in each layer of the pipe coil in an orderly manner.

[0062] Furthermore, a support platform 17H for supporting the loading platform is arranged on the movable seat 17C. A lifting rail (not shown in the figure) extending in the vertical direction is formed on the movable seat 17C, and the support platform 17H and the lifting rail form a sliding fit. The support platform 17H is moved up and down by a second group of ball transmission components (not shown in the figure). In addition, a plurality of bolt holes for positioning bolts to pass through are provided on the lifting rail, and a bolt groove matching the above-mentioned bolt holes is provided on the support platform 17H. When the upper block reaches a predetermined position, the support platform 17H can be locked on the lifting rail by the positioning bolts.

[0063] During the process of pipe winding, the pipe between the pipe coiler 10 and the pipe winder 20 is tightened by the hinge mechanism on the pipe winder 20 to maintain a certain tension. At this time, as the outer diameter of the pipe coil on the pipe winder 20 gradually increases, the winding position of the pipe also gradually changes. In this process, if the winding angle of the pipe is not adjusted, the pipe will cause significant wear and tear on the corresponding upstream and downstream components (such as the guide pipe 16A in this application), and even damage the pipe.

[0064] To this end, the present application provides an angle adjustment mechanism to solve the above problem. The angle adjustment mechanism is disposed between the support platform 17H and the support plate 11 to adjust the roll-in angle of the coil (see Figure 1 and Figure 5 ). Its angle adjustment mechanism includes a pair of valve seats 18A fixed on the lifting plate, a support shaft 18B supported on the pair of valve seats 18A, and an adjustment cylinder 18C. The support plate 11 is rotatably supported on the pair of valve seats 18B, thereby the support plate 11 can rotate around the axis of the support shaft.

[0065] The adjusting cylinder 18C includes a cylinder body rotatably connected to the support platform 17H and a cylinder shaft that can be extended relative to the cylinder body, and the end of the cylinder shaft away from the cylinder body is rotatably connected to the bottom of the support plate 11. Therefore, the carrying platform can be driven to rotate clockwise or counterclockwise around the axis of the support shaft 18B by controlling the extension and contraction of the cylinder shaft relative to the cylinder body, thereby achieving the purpose of adjusting the winding angle of the pipe.

[0066] Continue reading Figure 5-8 , which shows a tube winding machine 20 of a tube winding device 100, and the tube winding machine 20 can wind the tube into a tube coil of a preset size. Specifically, the tube winding machine 20 includes a base 21, a turntable 22 that can rotate around a first direction, and a hinge mechanism disposed on the turntable 22. The base 21 extends in a vertical direction and is supported on the ground, and the turntable 22 is rotatably supported on the base 21 and can drive the hinge mechanism to rotate together.

[0067] The hinge mechanism includes a plurality of hinge units 23 arranged circumferentially around a first direction, each hinge unit 23 including a support arm 23A for supporting other components, a fixed leaf 23B fixedly connected to the support arm 23A, a movable leaf 23C movably arranged on the support arm 23A, a hinge cylinder 23D for driving the movable leaf 23C to move, and a support plate 23E for supporting a coiled tube.

[0068] The fixed leaf 23B and the movable leaf 23C of each hinge unit are arranged opposite to each other along the first direction, and the fixed leaf 23B is closer to the base 21. The movable leaf 23C has a fifth position (eg, Figure 6 ) and a sixth position substantially parallel to the first direction (as shown Fig.10 When the movable page 23C is located at the fifth position, at least a portion of it is located on the moving path of the tube coil along the first direction to prevent the tube coil from escaping from the tube coiler 20; when the movable page 23C is located at the sixth position, it is completely out of the moving path of the tube coil along the first direction to allow the tube coil to escaping from the tube coiler 20.

[0069] The hinge cylinder 23D has a cylinder body rotatably connected to the support arm 23A and a cylinder shaft that can be extended relative to the cylinder body, and the end of the cylinder shaft away from the cylinder body is drivingly connected to the movable leaf 23C. Thus, the movable leaf can be driven by the hinge cylinder 23D to switch back and forth between the fifth position and the sixth position.

[0070] The supporting plate 23E is disposed between the fixed leaf 23B and the movable leaf 23C and is exposed to the outside. The hose is coiled and rolled on the multiple supporting plates 23E of the hinge mechanism and is confined between the movable leaf 23C and the fixed leaf 23B. It can be understood that the position of the supporting plates 23E of each hinge unit defines the inner diameter of the hose coil.

[0071] The support arms 23A of each hinge unit can be slidably arranged on the turntable 22 in the radial direction. Specifically, a plurality of hinge rails 22A extending in the radial direction are formed on the turntable 22, and each hinge support arm 23A forms a sliding configuration with the corresponding hinge rail 22A. Each hinge unit also includes a fixed nut (not shown in the figure), a movable nut (not shown in the figure), a rotating screw 23F, and a hand wheel 23G for the staff to rotate.

[0072] The rotating screw 23F is threadedly connected to the fixed nut and the movable nut at the same time, the fixed nut is fixedly mounted on the turntable 22, and the movable nut is fixedly mounted on the support arm 23A of the hinge unit. The hand wheel 23G is fixedly connected to one end of the rotating screw 23F and exposed to the outside, so that the staff can drive the movable nut to move in the radial direction by rotating the hand wheel 23G, that is, drive the support arm 23A of the hinge unit to slide in the radial direction.

[0073] The above structure allows the staff to adjust the distance between the plurality of support arms 23A on the turntable 22, thereby adjusting the inner diameter of the pipe coil when the coiled pipe is formed.

[0074] Furthermore, the hinge rail 22A is provided with a plurality of bolt holes (not shown in the figure) for positioning bolts to pass through, and the end of the support arm 23A near the hinge rail 22A is provided with a bolt groove (not shown in the figure) adapted to the bolt holes. When the support arm 23A reaches a predetermined position, the support arm 23A can be locked to the hinge rail 22A by the positioning bolt, that is, the radial position of the support arm 23A on the turntable 22 is locked.

[0075] Further, after the pipe coiling machine 10 cuts the pipe, the pipe located outside the pipe coil loses surface tension and may loosen. For this reason, the pipe coiling machine 20 is also equipped with a pressing component for pressing the pipe coil to prevent the pipe coil from loosening.

[0076] Specifically, the pressing assembly includes a bottom plate 24A fixedly mounted on the base 21 or the ground, a swing plate 24B swingably connected to the bottom plate 24A, a swing cylinder 24C for driving the pressing plate 24B to rotate, and a pressing plate 24D swingably mounted on the end of the swing plate 24B away from the bottom plate 24A. The pressing plate 24D is constructed to have a certain curvature and is equipped with rotatable rollers at both ends, so as to be suitable for pressing pipe coils of different outer diameters from the outside.

[0077] The swing plate 24B has a seventh position (eg, Figure 6 ) and forcing the pressing plate 24D to press against the eighth position of the pipe coil (such as Figure 7). The swing cylinder 24C has a cylinder body rotatably connected to the bottom plate 24A and a cylinder shaft that can be extended relative to the cylinder body, and the end of the cylinder shaft away from the cylinder body is rotatably connected to the swing plate 24B. Thus, the swing cylinder 24C can drive the pressure plate 24D to switch back and forth between the seventh position and the eighth position. Similarly, in other embodiments, power components such as motors, oil pumps, and electromagnetic actuators can also be used to replace the swing cylinder of this embodiment.

[0078] After the pipe is rolled, it needs to be bundled by the pipe bundling machine 30. Figure 6-7 The pipe strapping machine 30 includes a supply tray 31 for providing strapping tape, a base 32 for providing support, a controller 33 fixedly mounted on the base 32, and a first frame 34 and a second frame 35 for guiding the strapping tape. The first frame 34 is configured to be movable along a first direction to selectively move away from and approach the second frame 34. The first frame 23 and the second frame 35 are both configured to be movable along a second direction to selectively move toward and away from the inner space of the pipe coil.

[0079] When bundling, the first frame 34 of the pipe bundling machine 30 first moves along the first direction and away from the second frame 35; then, the first and second frames move along the second direction and reach the inner space of the pipe coil; then, the first frame 34 moves along the first direction and approaches the second frame 35 until the first and second frames are docked. As a result, the internal cavity parts of the first and second frames form a loop to guide the bundling belt to bundle the pipe coil, and the pipe bundling machine 30 uses this loop to bundle the pipe coil. After bundling is completed, the first and second frames return to their initial positions in the reverse steps of the above steps. Figure 9-11 , which shows a pipe material unloading machine 40 provided by the present application, which is used to unload the coiled hose. Specifically, the pipe material unloading machine 40 includes a base 41 for providing support, a bracket 42 movably mounted on the base along a first direction, a coil tray 43 movably mounted on the bracket 42, and a plurality of driving components.

[0080] The base 41 includes a pair of fixed rails 41A extending in the second direction and a pair of slide rails 41B mounted on the pair of fixed rails 41A. The pair of fixed rails 41A are arranged opposite to each other in the first direction, and both ends of each fixed rail 41A are locked on the ground by anchor bolts. The top of the pair of slide rails 41B is configured as an I-shaped groove, and the bracket 42 forms a sliding fit with the above-mentioned I-shaped groove, thereby achieving sliding in the first direction.

[0081] The driving component includes a first driving cylinder 41C for moving the bracket 42 and the coil tray 43 together. The first driving cylinder 41C includes a cylinder body fixedly mounted on the base 41 or the ground and a cylinder shaft that can be extended relative to the cylinder body. The end of the cylinder shaft away from the cylinder body is fixedly connected to the bottom of the bracket 42, thereby driving the bracket 42 and the coil tray 43 to move together on a pair of slide rails 41B. Similarly, in other embodiments, power components such as motors, oil pumps, and electromagnetic actuators can also be used to replace the first driving cylinder of this embodiment.

[0082] The coil tray 43 includes a tray body 43A configured to support the coiling of the hose, a fixed plate 43B fixedly mounted on one side of the tray body 43A, and a movable plate 43C movable along the first direction. The middle of the tray body 43A is recessed downward to form a concave portion with a certain arc, which is suitable for supporting the coiling of the pipe and providing positioning for the coiling of the pipe in the second direction to prevent the pipe from rolling out of the coil tray 43. The fixed plate 43B and the movable plate 43C are arranged opposite to each other along the first direction, and limit the coiling of the pipe from the first direction. Among them, the fixed plate 43B is closer to the bracket 42.

[0083] The movable plate 43C has a ninth position (eg, Fig. 9 ) and a tenth position away from the disk body 43A (as shown Fig.10 The coil tray 43 is also provided with a pair of second driving cylinders 43D. Each second driving cylinder 43D includes a cylinder body fixedly mounted on the tray 43A and a cylinder shaft that can be extended relative to the cylinder body. The end of the cylinder shaft away from the cylinder body is respectively fixedly connected to a pair of movable plates 43C, thereby driving the pair of movable plates 43C to switch back and forth between the ninth and tenth positions.

[0084] In other embodiments, the second driving cylinder may be eliminated and the movable plate may be fixedly mounted on the disk body, and the movement of the movable plate in the first direction may be completed by the first driving component.

[0085] A pair of lifting rails 42A extending in the vertical direction are arranged on the bracket 42, and the body 43A of the coil tray 43 forms a sliding fit with the pair of lifting rails 42A. The driving component also includes a pair of third driving cylinders 42E for driving the coil tray 43 to move up and down. Each third driving cylinder 42E includes a cylinder body fixedly mounted on the bracket 42 and a cylinder shaft that can be extended relative to the cylinder body. The end of the cylinder shaft away from the cylinder body is fixedly connected to the coil tray 43, and then drives the coil tray 43 to move on the pair of lifting rails 42A. Similarly, in other embodiments, power components such as motors, oil pumps, and electromagnetic actuators can also be used to replace the third driving cylinders of this embodiment.

[0086] Furthermore, the bracket 42 also includes a bottom frame 42B located at the bottom, a vertical frame 42C in an upright posture, and an inclined beam 42D arranged in an inclined manner. The bottom frame 42B forms a sliding fit with the base 41, and the lifting rail 42A is formed on the vertical frame 42C. The inclined beam 42D is located on the side of the vertical frame 42C close to the coil tray 43, and the two side ends of the inclined beam 42D are respectively fixedly connected to the vertical frame 42C and the bottom frame 42B, thereby forming a stable triangle to prevent the pipe unloading machine 40 from tipping over when transporting the pipe coil.

[0087] The working principle of the tube winding device 100 is described below:

[0088] See also Figure 1 and 5 After the pipe is produced by the upstream equipment, it is received by the pipe coiler 10. After the pipe passes through the loading platform along the pipe path, the guide cylinder 16D is activated, the guide pipe 16A is switched to the third position, and the pipe coiler 20 coils the pipe on the hinge mechanism with the cooperation of the pressing device. During the pipe coiling, the pipe coiler 10 continuously adjusts the pipe entry position and the entry angle.

[0089] See also Figure 6 After the pipe is rolled up, the guide cylinder 12C of the pipe coiling machine 10 is activated, and the guide member 12B is switched to the second position; the driving motor 13B stops running, the lifting cylinder 13E is activated, and the driven wheel 13D presses and brakes the pipe; the cutter cylinder 15C is activated to cut the pipe from the positioning port; the guide tube cylinder 16D is activated, and the guide tube 16A is switched to the fourth position.

[0090] See later Figure 7 , the swing cylinder 24C is actuated, and the pressing plate 24D presses the pipe coil from the outside; the pipe bundling machine 30 is actuated to bundle the pipe coil.

[0091] Last read Figure 7 , Fig.11 , Fig.12When the pipe coil is unloaded, each hinge cylinder 23D of the hinge mechanism is actuated, and the movable leaf 23C is switched to the sixth position to allow the pipe coil to be unloaded. The first driving cylinder 41C of the pipe unloading machine 40 is actuated, and the bracket 42 and the coil tray 43 are moved toward the pipe coil together; thereafter, a pair of second driving cylinders 43D are actuated, and a pair of movable plates 43C are switched to the tenth position and located in the gap between the pipe coil and the base 21; thereafter, a pair of third driving cylinders 42E are actuated, and the coil tray 43 moves upward, and the concave portion of the tray body 43A contacts and supports the pipe coil; thereafter, a pair of second driving cylinders 43D are actuated again, and a pair of movable plates 43C are switched to the ninth position and pull the pipe coil out of the hinge mechanism; thereafter, a pair of third driving cylinders 42E are actuated, and the coil tray 43 moves downward; finally, the first driving cylinder 42C is actuated again, and the coil tray 43 carrying the pipe coil exits the initial position, thereby completing the unloading.

[0092] By sequentially cycling through the above-mentioned stages, the tube winding device 100 continuously completes the processes of winding, winding, bundling and unloading.
