Description

Technical Field

[0001] The present invention relates to a winding device that winds a thread by rotating a spindle shaft, thereby forming a winding body. Background Technology

[0002] Previously, a turret-type winding device was known, which alternately winds a line on a pair of spindles. Specifically, the winding device includes: a turret that is rotatable in a circumferential direction; a plurality of spindles disposed on the turret that wind the line while rotating the spindles; a traverse device having a traverse guide that traverses the line by repeatedly moving along the axial direction of the spindles; and a control unit that controls the operation of the turret, spindles, and traverse device (see, for example, Patent Document 1).

[0003] Then, when the spindle at the winding position is fully wound to form a predetermined coil, the fully wound spindle at the winding position is positioned in a standby position by rotating the turret disc. At the same time, the empty spindle in the standby position is positioned at the winding position, and the line is changed from the fully wound spindle to the empty spindle. The line is then rewound on the empty spindle.

[0004] However, when changing the thread from a fully wound spindle to an empty spindle, the thread extending from the fully wound spindle to the empty spindle is cut off by a cutter located near the base end of the fully wound spindle. However, there is a problem that the end of the cut thread on the winding body side rotates randomly due to the inertial rotation of the winding body.

[0005] Therefore, a winding device is known in the past, which has a pressing roller that is used to press the end of the thread on the side of the winding body when the winding of the thread is completed and the thread of the winding body is cut (see Patent Document 2).

[0009] Patent Document 2: Japanese Patent Application Publication No. 2002-356274 Summary of the Invention

[0010] The problem that the invention aims to solve

[0011] However, while pressing the rollers does prevent the end of the line from running radially outward, the following situation occurs: as the winding body rotates inertially, the end of the line gradually approaches the base of the spindle, eventually falling to the exposed base of the winding body on the spindle and becoming entangled around the base of the spindle or its periphery (see...). Figure 7 Therefore, the following problems exist: when unloading the coil from the spindle, it is necessary to untangle the coil, which reduces work efficiency and raises concerns about damage to the coil or spindle.

[0012] The present invention was made in view of the above-mentioned problems, and aims to provide a winding device that prevents the cut wire on the winding body side from getting tangled around the base end of the spindle.

[0013] Technical solutions to the problem

[0014] To achieve the above objectives, the present invention provides a winding device that winds a line by rotating a main shaft to form a winding body. The device includes a pressing roller that presses the end of the line on the side of the winding body when the winding of the line is completed and the line of the winding body is cut. The pressing roller has grooves extending in the circumferential direction all over its circumferential surface.

[0015] Therefore, when the winding of the thread ends and the thread is cut, the pressing roller presses the end of the thread against the circumferential surface of the thread body, preventing the end of the thread from spinning randomly due to the inertial rotation of the thread body. Furthermore, since the end of the thread engages along the groove of the pressing roller when it reaches it, it is restricted from approaching the base end of the spindle, thus preventing the end of the thread from getting tangled around the base end of the spindle or its periphery.

[0016] Alternatively, the pressing roller can be formed in an inclined spiral shape, with the groove facing the winding body gradually moving towards the front end of the main shaft as it rotates in the opposite direction to the axis of the winding body. Thus, when the end of the line reaches the pressing roller as the axis of the winding body rotates, it is continuously fed to the front end of the main shaft while being inserted along the groove of the pressing roller and rotating in the opposite direction to the axis of the winding body. Therefore, it is possible to reliably prevent the end of the line from approaching the base end of the main shaft.

[0017] Alternatively, the pressing roller can be pressed against the circumferential surface of the yarn winding body. Thus, the pressing roller can naturally rotate in the opposite direction to the rotation of the yarn winding body's axis. Furthermore, when the end of the yarn reaches the pressing roller as the yarn winding body rotates, the end of the yarn can be reliably inserted into the groove of the pressing roller.

[0018] Alternatively, the device may include: an energizing mechanism for energizing the pressing roller; and an arm member, one end of which is connected to the pressing roller and the other end of which is connected to the energizing mechanism, wherein the pressing roller is pressed against the circumferential surface of the yarn body by being energized by the energizing mechanism through the arm member. Thus, a simple structure can be configured to reliably press the pressing roller against the circumferential surface of the yarn body with appropriate energizing force.

[0019] Furthermore, the present invention provides the aforementioned winding device, comprising: a turret rotatable in a circumferential direction; a plurality of spindles disposed on the turret, which wind the wire while rotating; a traversing device having a traversing guide that traverses the wire by repeatedly moving along the axial direction of the spindles; a cutting section that cuts the wire between the fully wound spindles and the empty spindles; and a control section that controls the operation of the turret rotatable, the spindles, and the traversing device.

[0020] The effects of the invention

[0021] According to the present invention, when the winding of the thread is completed and the thread of the winding body is cut, the end of the thread of the winding body is pressed against the circumferential surface of the winding body by the pressing roller, preventing the end of the thread from spinning randomly due to the inertial rotation of the winding body. Furthermore, since the end of the thread is inserted into the groove of the pressing roller when it reaches it, it is restricted from approaching the base end of the spindle, thus preventing the end of the thread from tangling around the base end of the spindle or its periphery. Therefore, not only can the winding body be easily removed from the spindle, speeding up the operation, but there is also no concern about damaging the winding body or the spindle, providing a high-quality winding body.

[0052] Next, referring to the winding device of the present invention... Figures 1-6 While explaining.

[0053] This winding device is as follows Figures 1-3 As shown, a turret-type winding device is used to alternately wind a line L around a pair of spindles 3. It includes: a base frame 1 with various structures; a turret 2 disposed on the base frame 1; a pair of spindles 3 disposed on the turret 2; a traversing device 4 disposed on the left side of the turret 2 in the base frame 1 (viewed from the front); a cutting assembly 5 disposed near the spindles 3 in the turret 2; a roller assembly 6 disposed on the right corner of the base frame 1 (viewed from the front); and a control unit (not shown) that controls the movement of the turret 2, spindles 3, traversing device 4, and cutting assembly 5.

[0054] The turret 2 is configured to rotate in a circumferential direction at the center of the front surface of the base frame 1, and is connected to a drive motor (not shown) located inside the base frame 1 via a predetermined rotation mechanism. By commanding the control unit, a pair of main shafts 3 are configured to rotate 180 degrees to the left when viewed from the front.

[0055] The main shaft 3 is supported on one side in a forward-projecting manner at a symmetrical position on the concentric circle of the turret disk 2, such as... Figure 1 As shown, the configuration is switched between the winding position A on the left side of the front view and the standby position B on the right side of the front view by rotating the turret disk 2.

[0056] Furthermore, the main shaft 3 is connected to a drive motor (not shown) located inside the base frame 1 via a predetermined rotation mechanism. Under the command of the control unit, the main shaft rotates the thread L at the winding position A, winding it from an empty state to a fully wound state. Additionally, when winding the thread L, the main shaft 3 has a bobbin mounted on its main body 32 (bobbin seat). The thread L is sequentially wound onto this bobbin to form a coil P of thread L with a predetermined diameter.

[0057] The traversing device 4 includes: a traversing device body 41, which is provided to protrude forward from the base frame 1 along the axial direction of the main shaft 3; and a traversing guide 42, which is provided on the traversing device 4. The traversing guide 42 is connected to a drive motor (not shown) via a predetermined cam shifting mechanism, and has a reversing position X1 on the front end 30 side and a reversing position X2 on the base end 31 side along the axial direction of the main shaft 3 (see reference). Figure 1 The wires move repeatedly between the two sides, thereby guiding the line L, which is sent from outside the device, across the main shaft 3, which rotates on the winding position A.

[0058] Furthermore, when the traverse device 4 changes the line L from the fully wound spindle 3 to the empty spindle 3, the traverse guide 42 moves past the reversing position X2 on the base end 31 side of the repeatedly moving base end 31 side to the base end 31 side of the empty spindle 3 at the winding position A. Thus, after the line L is pulled into the base end 31 side of the spindle 3, it moves back to the reversing position X2 on the base end 31 side.

[0059] Cutting assembly 5 is a cutting device for cutting line L, such as... Figure 1 As shown, it is disposed around the base end 31 of each spindle 3. When the line L is changed from the fully wound spindle 3 to the empty spindle 3, the cutting assembly 5 captures and cuts the line L between the fully wound spindle 3 and the empty spindle 3.

[0060] like Figure 4 As shown, the roller assembly 6 includes: a pressing roller 61 for pressing the end portion LE of the line L on the side of the winding body P when the winding of the line L is finished and the line L is cut off; an energizing mechanism 62 for energizing the pressing roller 61 onto the winding body P; and an arm member 63, one end of which is connected to the pressing roller 61 and the other end of which is connected to the energizing mechanism 62. Furthermore, the so-called end portion LE of the line L is a portion of a predetermined length measured from the cut surface of the cut line L on the side of the winding body P, generally referring to the portion that moves radially outward as the axis of the winding body P rotates.

[0061] The pressing roller 61 is moderately energized by the energizing mechanism 62 via the arm member 63, thereby being pressed against the circumferential surface of the base end of the yarn body P, and the pressing roller 61 rotates in accordance with the axis of the yarn body P. Figure 2 (counterclockwise) and in the opposite direction to the axis of the winding body P (rotation counterclockwise) Figure 2 It rotates naturally clockwise.

[0062] Therefore, when the winding line L is finished and the line L of the winding body P is cut, the end part LE of the line L of the winding body P is pressed against the circumferential surface of the winding body P by the pressing roller 61, thus preventing the end part LE of the line L from spinning randomly due to the inertial rotation of the winding body P.

[0063] Furthermore, the pressing roller 61 has grooves 61a extending in the circumferential direction along its length all over its circumferential surface. Especially in this embodiment, as... Figure 5 As shown, when the groove 61a rotates in the opposite direction to the axis of the winding body P, it is formed into an inclined spiral shape with the groove 61a opposite to the winding body P gradually moving towards the front end 30 side of the main shaft 3, and has a width and depth larger than the diameter of the wound line L.

[0064] Therefore, as Figure 5 As shown, when the end portion LE of the line L reaches the pressing roller 61 as the axis of the winding body P rotates, it is continuously fed to the front end portion 30 side of the main shaft 3 while being inserted along the groove 61a of the pressing roller 61 and rotating in the opposite direction to the axis of the winding body P of the pressing roller 61.

[0065] If we were to explain in more detail, it would be as follows: Figure 5 As shown, if the pressing roller 61 rotates in the direction opposite to the rotation of the axis of the winding body P, it will rotate in the same direction as the axis of the winding body P. Figure 5 Rotate naturally in the direction of the arrow, and the contact point between the end of line L (LE) and the pressing roller 61 will be as follows: Figure 5 As indicated by the arrow, the feed is directed along the groove 61a to the front end 30 side of the main shaft 3 in the order of K1, K2, K3, K4, K5.

[0066] Therefore, even assuming that the end portion LE of line L approaches the base end portion 31 of the spindle 3 during the period when it is not pressed by the pressing roller 61, since the end portion LE of line L will be sent to the front end portion 30 of the spindle 3 when it reaches the pressing roller 61, the end portion LE of line L is restricted from approaching the base end portion 31 of the spindle 3, thus preventing the end portion LE of line L from getting tangled in the base end portion 31 of the spindle 3 or its periphery.

[0067] Next, regarding the overall action of winding line L by this device, while referring to... Figure 1 While explaining.

[0068] First, after the spindle 3 in the empty state of the winding position A holds the line L, the spindle 3 in the empty state winds the line L while rotating the spindle, and continues to wind the line L until it becomes a fully wound state of the winding body P of the predetermined diameter.

[0069] Then, when the spindle 3 at winding position A is in a fully wound state, the spindle 3 in the fully wound state at winding position A is positioned in standby position B by rotating the turret disk 2, and the configuration is changed in such a way that the spindle 3 in the empty state at standby position B is positioned in winding position A.

[0070] Then, after changing the spindle 3 from the fully wound state at the standby position B to the empty state at the winding position A, the spindle 3 rewinds the spindle L in the empty state and pulls the coil P off the spindle 3 in the fully wound state.

[0071] Next, regarding the actions of cutting line L when changing the spindle 3 from a fully wound state to an empty state, and the actions after cutting, refer to... Figure 6 While explaining.

[0072] As described above, when the main shaft 3 in the fully wound state at the rotating winding position A of the turret disk 2 is placed in the standby position B, and the configuration is changed such that the main shaft 3 in the empty state at the standby position B is placed in the winding position A, the drive to rotate the main shaft 3 in the fully wound state is released.

[0073] Furthermore, the lateral movement device 4 moves towards the base end 31 side of the main shaft 3 at the winding position A by passing the folding position X2 on the repeatedly moving base end 31 side via the lateral movement guide 42, and after pulling the line L into the base end 31 side of the main shaft 3, it is held in the empty state of the main shaft 3 at the winding position A.

[0074] Furthermore, the cutting assembly 5 captures and cuts the thread L on the base end 31 side of the spindle 3 in the fully wound state, which is pulled into the standby position B. Specifically, regarding the movement of the thread L at this time, before cutting the thread L, the axial position of the thread L wound on the winding body P is restricted by the end face drop-limiting guide 71 of the thread rod 7 located below the spindle 3, placing it slightly ahead of the base end 31 of the spindle 3. Then, after cutting the thread L, the end portion LE of the thread L on the winding body P runs wild and is about to deviate from the aforementioned position towards the base end 31 side of the spindle 3, but this deviation is suppressed by the pressing roller 61 described later, which holds the end portion LE of the thread L in place. Additionally, the spindle 3 in the fully wound state of the standby position B is de-driven and rotates inertially in the rotational direction during winding.

[0075] Next, when the end portion LE of the line L reaches the pressing roller 61 as the axis of the winding body P rotates with the axis of the main shaft 3, the end portion LE of the line L is intermittently pressed onto the circumferential surface of the winding body P.

[0076] To explain in detail, firstly, as... Figure 6 As shown in (a), when the end portion LE of the line L of the winding body P reaches the pressing roller 61, the root portion LE1 of the end portion LE of the line L is pressed against the circumferential surface of the winding body P, and then as shown in (a). Figure 6 As shown in (b), press the middle part LE2 of the end portion LE of line L onto the circumferential surface of the coil body P, and then as follows. Figure 6 As shown in (c), the front end LE3 of the end portion LE of line L is pressed onto the circumferential surface of the coil body P.

[0077] At this time, such as Figure 5As shown, since the pressing roller 61 rotates naturally in the opposite direction to the rotation of the axis of the winding body P, the end portion LE of the line L is inserted along the groove 61a of the pressing roller 61 and is fed to the front end of the main shaft 3 in the order of contacts K1, K2, K3, K4, K5 along the groove 61a in the opposite direction to the rotation of the axis of the winding body P of the pressing roller 61.

[0078] Furthermore, during the inertial rotation of the winding P, the pressing action of the pressing roller 61 on the circumferential surface of the winding P, which presses the end portion LE of the line L, and the intermittent conveying action of the end portion LE of the line L toward the front end portion 30 of the spindle 3, prevents the end portion LE of the line L from running outward in the radial direction and limits its proximity to the base end portion 31 of the spindle 3, thus preventing the end portion LE of the line L from getting tangled in the base end portion 31 of the spindle 3 or its periphery. Therefore, not only can the winding P be easily unloaded from the spindle 3, thus speeding up the operation, but there is also no concern about damaging the winding P or the spindle 3, enabling the delivery of a high-quality winding P.

[0079] Furthermore, in the above embodiments, the pressing roller 61 is provided with a groove 61a formed in a spiral shape, but it can also be formed in other shapes.

[0080] Furthermore, the pressing roller 61 is configured to be pressed completely onto the circumferential surface of the winding body P, but it may also be configured to form a slight gap with the winding body P.

[0081] Furthermore, the pressing roller 61 is configured to be pressed onto the circumferential surface of the winding body P by the energizing mechanism 62 and the arm member 63, but it can also be pressed onto the circumferential surface of the winding body P by other mechanisms.

[0082] Furthermore, the pressing roller 61 is configured to rotate naturally in the opposite direction to the axis of the winding body P by being pressed against the circumferential surface of the winding body P, but it can also be forced to rotate by an additional drive mechanism.

[0083] Furthermore, the pressing roller 61 is located at the front right corner of the base frame 1, but it can also be located at other positions around the winding body P on the standby position B of the spindle 3.

[0084] Furthermore, the winding device is described as a tower-type winding device, but it may also be other types of winding devices.

[0085] Furthermore, the thread L wound by the winding device is not only made of polyester twisted yarn, nylon, polyester processed yarn, polypropylene monofilament and other fiber yarns, but also includes various types of thread-like objects of all materials, such as metal threads.

[0086] The embodiments of the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to the embodiments shown in the drawings. Various modifications or variations can be applied to the embodiments shown in the drawings within the same or equivalent scope as the present invention.
