Description

Technical Field

[0001] This disclosure relates to a winding apparatus and a winding method. More specifically, it relates to a winding apparatus for continuously and automatically forming a bundle of wires from a preceding process into a bundle of wires, and a winding method using the same apparatus. In this disclosure, a wire refers to one or more solid wires or one or more hollow wires. Background Technology

[0002] Examples of conventional winding devices for winding linear bodies include Patent No. 3623874 (Patent Document 1), Patent No. 4477866 (Patent Document 2), and Patent No. 4574725 (Patent Document 3).

[0003] The winding apparatuses disclosed in Patent Documents 1 to 3 arrange winding frames side by side on the coaxial axis. When the winding of the linear body to one winding frame is completed, the linear body is moved to the other winding frame, thereby starting the winding of the linear body to the other winding frame.

[0004] After the winding of the linear body into the other winding frame begins, the winding frame on the side where the winding of the linear body is completed stops the rotation. Then, the bundle of linear body wound in the winding frame is covered with paper, film, etc., and both ends are cut off. Then, the bundles of linear body covered with film are sequentially retrieved.

[0008] Patent Document 2: Patent No. 4477866

[0009] Patent Document 3: Patent No. 4574725 Summary of the Invention

[0010] The problem that the invention aims to solve

[0011] In the winding apparatus disclosed in Patent Documents 2 and 3, in order to minimize the transition line generated when switching the winding of the linear body from one winding frame to another, it is necessary to temporarily stop the winding during the switching, and thus employ a mechanism called an accumulation mechanism (relaxation absorption mechanism) to absorb the slack of the line generated at this time.

[0012] Here, when the winding of the wire body into one winding frame is completed, the wire body is moved to the other winding frame, thereby beginning the winding of the wire body into the other winding frame. At this time, a transition line is generated between the winding frames of one side and the winding frame of the other side.

[0013] Since the transition line will be discarded, it is preferable to keep it as short as possible. Furthermore, if the transition line is long, there is a risk that the transition line may easily get mixed into the bundle of linear material when it is wrapped with paper, film, or the like and then cut off at both ends for recycling. In particular, it is considered that when the transition line is tilted, as in Patent Document 1, the transition line is also easily mixed into the bundle of linear material from a positional perspective when it is cut.

[0014] Thus, without an accumulation mechanism, the risk of transitional fibers being introduced into the bundle of yarn increases. If an accumulation mechanism is used, the risk of yarn quality degradation due to twisting, scratches, and other damage caused by the operation of the accumulation mechanism increases.

[0015] The purpose of this disclosure is to solve the above-mentioned problems by providing a winding apparatus and winding method that can simultaneously reduce the risk of contamination of transition lines and the risk of quality degradation of the linear body.

[0016] Solution for solving the problem

[0017] [1] In the winding apparatus of this disclosure, the winding apparatus includes a first winding frame and a second winding frame having the same shape as the first winding frame, and a wire is wound onto the first winding frame while the first winding frame rotates, or the wire is wound onto the second winding frame while the second winding frame rotates. The first winding frame has a first rotating mechanism that rotates about a rotation axis, and the second winding frame has a second rotating mechanism that rotates coaxially with the rotation axis. The first rotating mechanism and the second rotating mechanism have a winding frame moving device that relatively changes the distance between the first winding frame and the second winding frame in the axial direction of the rotation axis. A wire supply switching device is provided at a predetermined distance from the second winding frame to supply the wire to either the first winding frame or the second winding frame and to switch the supply of the wire to either the first winding frame or the second winding frame. The first winding frame includes a first wire holding and cutting mechanism that holds the wire and cuts the wire. The second winding frame includes a second wire holding and cutting mechanism that holds the wire and cuts the wire. The first rotation mechanism and the second rotation mechanism are capable of synchronizing the rotation of the first winding frame and the second winding frame by generating a predetermined phase difference between the first wire holding and cutting mechanism and the second wire holding and cutting mechanism from opposite positions.

[0018] [2]: According to the winding device described in [1], the first winding frame includes two or more first arms arranged radially, the second winding frame includes two or more second arms arranged radially, the first linear body holding and cutting mechanism is disposed at a position on the side of a selected first arm opposite to the second winding frame, and the second linear body holding and cutting mechanism is disposed at a position on the side of a selected second arm opposite to the first winding frame.

[0019] [3]: According to the winding device described in [1] or [2], both the first wire holding and cutting mechanism and the second wire holding and cutting mechanism have: an introduction region for receiving the wire; a block for fixing the wire in the introduction region; and a cutting device for cutting the wire fixed by the introduction region and the block.

[0020] [4]: The winding method disclosed herein is a winding method for a linear body using a winding device of any one of [1] to [3], wherein the winding method for the linear body comprises the following steps: the second winding frame, which is in a stopped state, begins to rotate synchronously with the rotational speed of the first winding frame, which is in a rotating state, and the rotation of the first winding frame and the second winding frame is synchronized by generating a predetermined phase difference between the first linear body holding and cutting mechanism of the first winding frame and the second linear body holding and cutting mechanism of the second winding frame; the second winding frame is moved along the axial direction of the rotation axis to a side close to the first winding frame by the winding frame moving device; and at the stage where the number of turns of the linear body wound toward the first winding frame reaches a predetermined number of turns, the linear body is moved toward the second winding frame by the linear body supply switching device, and the winding of the linear body toward the second winding frame begins.

[0021] [5]: According to the winding method described in [4], after the step of synchronizing the rotation of the first winding frame and the second winding frame by generating a predetermined phase difference between the first wire holding and cutting mechanism of the first winding frame and the second wire holding and cutting mechanism of the second winding frame, the second winding frame is moved along the axial direction of the rotation axis to a position close to the first winding frame by means of the winding frame moving device. Then, at the stage where the number of turns of the wire towards the first winding frame reaches a predetermined number of turns, the wire is moved towards the second winding frame by means of the wire supply switching device and the winding of the wire towards the second winding frame begins.

[0022] [6]: According to the winding method described in [4] or [5], the winding method further includes the following steps: while maintaining the rotational speed of the second winding frame by the second rotating mechanism in such a way that the length of the transition line generated between the first winding frame and the second winding frame does not change, while adjusting the rotational speed and phase difference of the first winding frame relative to the second winding frame by the first rotating mechanism, the first winding frame is moved away from the second winding frame by the winding frame moving device.

[0023] [7]: According to the winding method described in [6], the winding method further comprises the following steps: holding the wire using the first wire holding and cutting mechanism and the second wire holding and cutting mechanism; and cutting the wire using the first wire holding and cutting mechanism and the second wire holding and cutting mechanism.

[0044] Hereinafter, a winding apparatus based on various embodiments of the present disclosure and a winding method using the winding apparatus will be described with reference to the accompanying drawings. In the embodiments described below, when the number, quantity, etc., are mentioned, the scope of the present invention is not limited to that number, quantity, etc. unless specifically stated otherwise. Sometimes the same reference numerals are used to mark the same or equivalent parts, and will not be described again. The appropriate combination of the structures of the embodiments was determined from the beginning.

[0045] In the following description, the case of setting up two winding frames for winding wire bodies S arranged coaxially is described, but it is not limited to two frames, and also includes the case of setting up three or more winding frames coaxially. In the following description, wire body S refers to one or more solid wires or one or more hollow wires.

[0046] [Comparative Example: Winding Method]

[0047] Reference Figures 1 to 5 As a comparative example, a conventional method for winding linear bodies will be described. Figure 1 This is a schematic diagram illustrating the winding process of the winding method using the winding apparatus of the comparative example. Figure 2 This is a schematic diagram illustrating the switching process. Figure 3 This is a schematic diagram illustrating the transition line cutting process. Figure 4 This is a schematic diagram showing the stopping process of the first winding frame. Figure 5 This is a schematic diagram illustrating the coating process. It should be noted that in the following comparative winding methods, the case where an accumulation mechanism is not used is shown. In each figure, (A) is a schematic diagram of a top view of the winding frame, and (B) is a schematic diagram of a side view of the first winding frame 10.

[0048] Reference Figure 1 In this winding device, both the first winding frame 10 and the second winding frame 20 are regular hexagonal polygons, arranged with their vertices facing each other. The first winding frame 10 and the second winding frame 20 are arranged side by side on the same rotation axis a1, and the first winding frame 10 and the second winding frame 20 rotate in the direction indicated by arrow R in the figure.

[0049] exist Figure 1 In the winding process shown, a wire S is wound around the first winding frame 10. The wire S is wound around the winding frame in a manner that connects the vertices of the first winding frame 10. A wire supply switching device 40 is provided outside the first winding frame 10. The traverse guide 40b is configured to reciprocate in the direction indicated by arrow Y in the figure. The traverse guide 40b has a mechanism for switching the externally supplied wire S to the first winding frame 10 and the second winding frame 20.

[0050] exist Figure 2In the switching process shown, the first winding frame 10 reaches the predetermined number of turns, thereby completing the winding of the linear body S using the first winding frame 10. Then, the linear body S supplied from the outside moves from the first winding frame 10 to the empty winding frame 20 via the linear body supply switching device 40, and the winding of the linear body S begins using the second winding frame 20. At this time, a transition line S1 is generated between the first winding frame 10 and the second winding frame 20.

[0051] exist Figure 3 In the transition line cutting process shown, the transition line S1 is cut by the cutting device 50 disposed between the first winding frame 10 and the second winding frame 20. Transition lines S1 remain in both the first winding frame 10 and the second winding frame 20. When the bundle is wrapped into a linear body to form the product, longer strands of the remaining transition line S1 remain in locations where contamination cannot be prevented.

[0052] exist Figure 4 The diagram shows the first winding frame 10 stopping at its stop point. In this diagram, the remaining transition line S1 is located at the bottom.

[0053] exist Figure 5 In the coating process shown, the externally mounted coating device 300 moves to a position below the first winding frame 10 and coats the bundle of linear bodies S located between the vertices of the first winding frame 10 with film F. Then, the two ends of the bundle of linear bodies S are cut off, thereby forming a bundle of linear bodies S wound with film F. The bundle of linear bodies S is removed by rotating the first winding frame 10 sequentially (60 degrees in the illustrated structure). It should be noted that at the vertices of the first winding frame 10, a clamping mechanism (not shown) is used to hold the bundle of linear bodies S.

[0054] During the wrapping of the bundle of linear bodies S, the transition line S1 sometimes gets mixed into the interior of the bundle of linear bodies S. In particular, when the transition line S1 is long, and when the transition line S1 is arranged at an angle relative to the bundle of linear bodies S, it is impossible to control the transition line S1, resulting in the transition line S1 getting mixed into the interior of the bundle of linear bodies S. As a result, the product containing the transition line S1 is a defective product.

[0055] The winding apparatus of the embodiment and the winding method using the winding apparatus will be described below.

[0056] (Implementation method: winding device 1)

[0057] Reference Figure 6 The winding apparatus 1 of this embodiment will be described. Figure 6This is a schematic diagram showing the general structure of the winding device 1. In this disclosure, a linear body refers to one or more solid wires or one or more hollow wires.

[0058] The winding device 1 includes a first winding frame 10 and a second winding frame 20 with the same shape as the first winding frame 10. In this embodiment, the first winding frame 10 has six first arms 11a arranged radially from the first main body 11 at 60-degree intervals. First wire frames 11b are respectively provided at the front end of each of the first arms 11a. The second winding frame 20 has six second arms 21a arranged radially from the second main body 21 at 60-degree intervals. Second wire frames 21b are respectively provided at the front end of each of the second arms 21a.

[0059] While the first winding frame 10 rotates, the winding device 1 winds the wire S into the first winding frame 10 while holding it from the first wire frame 11b, connecting the apex of the first arm 11a. Alternatively, while the second winding frame 20 rotates, the wire S is wound into the second winding frame 20 while holding it from the second wire frame 21b, connecting the apex of the second arm 21a. The winding method of the wire S using this winding device 1 will be described later.

[0060] The first winding frame 10 has a first rotating mechanism 12 that rotates about a rotation axis a1. The first rotating mechanism 12 is held in the first frame F10. The second winding frame 20 has a second rotating mechanism 22 that rotates coaxially with the rotation axis a1. The second rotating mechanism 22 is held in the second frame F20.

[0061] The first rotating mechanism 12 and the second rotating mechanism 22 have a winding frame moving device 30 in the axial direction of the rotating shaft a1, which moves the gap between the first winding frame 10 and the second winding frame 20 relatively.

[0062] The winding frame moving device 30 can also be any of the following mechanisms: a mechanism that enables the first rotating mechanism 12 to move axially along the rotating shaft a1 and sets the second rotating mechanism 22 to a fixed state; a mechanism that enables the second rotating mechanism 22 to move axially along the rotating shaft a1 and sets the first rotating mechanism 12 to a fixed state; or a mechanism that enables both the first rotating mechanism 12 and the second rotating mechanism 22 to move axially along the rotating shaft a1.

[0063] At a predetermined distance from the first winding frame 10 and the second winding frame 20, a wire supply switching device 40 is provided to supply a wire S to either the first winding frame 10 or the second winding frame 20 and to switch the supply of the wire S to either the first winding frame 10 or the second winding frame 20. The wire supply switching device 40 includes a guide frame 40a and a lateral guide 40b that moves along the guide frame 40a. The lateral guide 40b is configured to reciprocate along the guide frame 40a in the direction of arrow Y in the figure. The wire S is fed out from the lateral guide 40b in the direction of arrow T in the figure.

[0064] At the apex of the first arm 11a selected in the first winding frame 10, in addition to the first wire frame 11b, a first wire holding and cutting mechanism 110 is provided, capable of holding and cutting the wire S. At the apex of the second arm 21a selected in the second winding frame 20, in addition to the second wire frame 21b, a second wire holding and cutting mechanism 210 is provided, capable of holding and cutting the wire S.

[0065] (Winding method)

[0066] Next, refer to Figures 7 to 12 The winding method of the linear body S using the winding device 1 constructed with the above-described structure will be described. Figure 7 This is a schematic diagram illustrating the first preparatory step of a winding method using winding device 1. Figure 8 This is a schematic diagram showing the second preparation step. Figure 9 This is a schematic diagram illustrating the movement process of the lateral guide. Figure 10 This is a schematic diagram showing the start of the winding process for the second winding frame. Figure 11 This is a schematic diagram illustrating the preparation process for cutting the transition line. Figure 12 This is a schematic diagram illustrating the transition line cutting process. Each diagram is derived from... Figure 6 The diagram shows the first winding frame 10 and the second winding frame 20 viewed in the direction of arrow V. It should be noted that the structures of the first linear body holding and cutting mechanism 110 and the second linear body holding and cutting mechanism 210 are described later.

[0067] (Synchronous rotation process of the winding frame)

[0068] Reference Figure 7 The synchronous rotation process of the winding frame is described below. During the period when the linear body S is wound on the first winding frame 10, the wrapping of the bundle of linear body S wound on the second winding frame 20 is completed, and all the bundle of linear body S is retrieved from the second winding frame 20, and preparation for the next process begins.

[0069] Specifically, the second winding frame 20, which is in a stopped state, begins to rotate in sync with the rotational speed of the first winding frame 10, which is in a rotating state. At this time, the rotation of the first winding frame 10 and the second winding frame 20 is synchronized by generating a predetermined phase difference (position offset) between the first wire-shaped body holding and cutting mechanism 110 of the first winding frame 10 and the second wire-shaped body holding and cutting mechanism 210 of the second winding frame 20.

[0070] The purpose of imparting a phase difference is to ensure that, when switching the winding of the wire S from the first winding frame 10 to the second winding frame 20 using the lateral guide 40b (described later), the wire S is positioned at an angle that facilitates engagement with the second wire frame 21b disposed on the second winding frame 20. The phase difference between the first wire holding and cutting mechanism 110 and the second wire holding and cutting mechanism 210 is determined based on factors such as the number of arms of the winding device 1, the length of the arms, and the winding speed; for example, a phase difference of approximately 5 to 30 degrees is selected.

[0071] (Approaching the winding frame process)

[0072] Next, refer to Figure 8 The approach process of the winding frame is explained. The second winding frame 20 is moved along the axial direction of the rotation axis a1 towards the side of the first winding frame 10 by the winding frame moving device 30 (in the direction of arrow D1 in the figure). This is to minimize the transition line S1 (see reference) between the first winding frame 10 and the second winding frame 20 when switching the lateral guide 40b (described later) from the first winding frame 10 to the second winding frame 20. Figure 9 The length of ).

[0073] (Transverse guide movement process)

[0074] Next, refer to Figure 9 The process of moving the lateral guide is described. When the number of turns of the linear body S in the first winding frame 10 reaches the specified number of turns, the lateral guide 40b of the linear body supply switching device 40 is moved toward the second winding frame 20.

[0075] (Start the winding process for the second roll of the frame)

[0076] Next, refer to Figure 10The winding process of the wire S into the second winding frame will be explained. The wire S, delivered from the traverse guide 40b, engages with the second wire frame 21b on one side of the second winding frame 20, thereby initiating the winding of the wire S into the second winding frame 20. At this time, since a phase difference is provided between the first winding frame 10 and the second winding frame 20, the wire S is positioned at an angle that makes it easy to engage with the second wire frame 21b provided in the second winding frame 20, thereby suppressing the occurrence of switching errors of the wire S. Furthermore, by initiating the winding into the second winding frame, a transition line S1 is generated between the first winding frame 10 and the second winding frame 20.

[0077] (Preparation process for cutting the transition line)

[0078] Next, refer to Figure 11 The preparation process for cutting the transition line is explained. While maintaining the rotational speed of the second winding frame 20 via the second rotating mechanism 22, the rotational speed and phase difference of the first winding frame 10 relative to the second winding frame 20 are adjusted via the first rotating mechanism 12. The first winding frame 10 is then moved away from the second winding frame 20 (in the direction of arrow D2 in the figure) via the winding frame moving device 30.

[0079] When the first winding frame 10 moves, the movement, rotation speed and phase difference of the first winding frame 10 are adjusted by pulling the transition line S1 out in a direction that is as perpendicular as possible to the first winding frame 10 and the second winding frame 20.

[0080] This is so that in the transition line cutting process described later, the transition line S1 can be easily held and cut by the first linear body holding and cutting mechanism 110 and the second linear body holding and cutting mechanism 210, and the transition line S1 can be kept away from the bundle of linear body S wound on the first winding frame 10, thereby preventing the transition line S1 from mixing into the bundle of linear body S.

[0081] (Transition line cutting process)

[0082] Reference Figure 12 The transition line cutting process is described below. The wire S is held by the first wire holding and cutting mechanism 110 and the second wire holding and cutting mechanism 210. Then, the wire S is cut by the first wire holding and cutting mechanism 110 and the second wire holding and cutting mechanism 210. This disconnects the transition line S1 from the first winding frame 10 and the second winding frame 20.

[0083] Then, the winding of the linear body S continues in the second winding frame 20, the first winding frame 10 stops rotating, and the bundle of linear body S is cut starting from the first winding frame 10. During the cutting of the bundle of linear body S, as... Figure 5 As shown, the wrapping device 300 is used to cut the bundle of linear body S.

[0084] Then, the linear body S is wound alternately into the first winding frame 10 and the second winding frame 20, and the bundle of linear body S is cut in sequence using the covering device 300.

[0085] In this way, according to the winding method of the linear body S using the winding device 1 described above, the transition line S1 is shortened and the transition line S1 is pulled out in a direction that is approximately perpendicular to the first winding frame 10, so that the risk of the transition line S1 being mixed into the bundle of the linear body S can be reduced during the wrapping process.

[0086] (Linear body holding and cutting mechanism)

[0087] Next, refer to Figure 13 The general structure of the linear body holding and cutting mechanism will be described. Since the first linear body holding and cutting mechanism 110 provided in the first winding frame 10 has the same structure as the second linear body holding and cutting mechanism 210 provided in the second winding frame 20, the specific structure of the second linear body holding and cutting mechanism 210 will be described here.

[0088] A second wire frame 21b with a recessed shape is provided on one side of the front end portion of the second arm 21a. The second wire frame 21b is provided on the opposite side to the surface opposite to the surface of the first winding frame 10. At the front end portion of the second arm 21a, when viewed along the rotation direction of the second arm 21a (arrow R in the figure), triangular recessed introduction areas 230 for receiving the wire body S are provided on the upstream and downstream sides respectively.

[0089] A block 240 is provided in the introduction area 230, which is configured to move between the position of the open introduction area 230 and the position of the closed introduction area 230 (keeping the position of the linear body S) (in the direction of arrow H in the figure). The block 240 has a shape corresponding to the triangular recess of the introduction area 230.

[0090] On the other side of the front end portion of the second arm 21a (the side opposite to the first winding frame 10), there are two cutting tools 220 that can slide along the extension direction of the second arm 21a (arrow X direction in the figure).

[0091] Next, refer to Figures 14 to 18 The fixing and cutting of the wire S using the second wire holding and cutting mechanism 210 having the above structure will be described. Figures 14 to 18 Figures 1 through 5 illustrate the operation of the linear body holding and cutting mechanism, but... Figure 14 and Figure 10 The "winding start process for the second winding frame" corresponds to this. Figure 15 and Figure 11 The "transition line cutting preparation process" corresponds to this. Figures 16 to 18 and Figure 12 The "transition line cutting process" corresponds to this.

[0092] Reference Figure 14 ,like Figure 10 As shown in the "winding start process to the second winding frame", the wire S delivered from the traverse guide 40b engages with the second wire frame 21b on one side of the second winding frame 20, and the winding of the wire S into the second winding frame 20 begins. At this time, since there is a phase difference between the first winding frame 10 and the second winding frame 20, the wire S is at an angle that makes it easy to engage with the second wire frame 21b provided on the second winding frame 20.

[0093] Reference Figure 15 ,like Figure 11 As shown in the "Transition Line Cutting Preparation Process", while maintaining the rotational speed of the second winding frame 20, the length of the transition line S1 between the first winding frame 10 and the second winding frame 20 remains unchanged, while adjusting the rotational speed and phase difference of the first winding frame 10 relative to the second winding frame 20, and moving the first winding frame 10 in the direction away from the second winding frame 20 (arrow D2 direction in the figure).

[0094] When the first winding frame 10 moves, the movement, rotation speed and phase difference of the first winding frame 10 are adjusted by pulling the transition line S1 out in a direction that is as perpendicular as possible to the first winding frame 10 and the second winding frame 20.

[0095] Reference Figures 16 to 18 right Figure 12 The "transition line cutting process" will be explained. For example... Figure 16 as well as Figure 17 As shown, block 240 is moved in the direction H in the figure, thereby fixing the linear body S located in the introduction area 230 between the introduction area 230 and block 240 by the second linear body holding and cutting mechanism 210.

[0096] Next, as Figure 18 As shown, the cutter 220 slides along the direction of arrow X in the figure and cuts the transition line S1 from the linear body S. Thus, while maintaining the linear body S fixed to the second arm 21a of the second winding frame 20, the transition line S1 is cut from the second arm 21a.

[0097] The winding of the linear body S continues in the second winding frame 20, while in the first winding frame 10... Figure 5 The coating apparatus 300 shown performs a coating process on a bundle of linear bodies S.

[0098] According to the winding apparatus 1 of this embodiment and the winding method using the winding apparatus 1, it is possible to reduce the risk of the transition line being mixed into the product while shortening the transition line.

[0099] It should be noted that the first winding frame 10 and the second winding frame 20 in the above embodiments each have a hexagonal shape with six arms extending radially and winding at six points, but are not limited to hexagonal winding frames. A two-point winding frame winding at two points can also be used. In addition, a circular winding frame can also be used.

[0100] The embodiments disclosed herein should be considered illustrative in all respects and not restrictive. The scope of the invention is indicated by the technical solutions rather than the foregoing description, and is intended to include all modifications of the same meaning and scope.
