Description

[Technical field]

[0001] The present invention relates to a tape winding machine that supports an object onto which the tape is to be wound while winding a roll of tape around the object. [Background technology]

[0002] Conventionally, as part of the manufacture of vehicle wire harnesses, tape winding devices have been proposed that wind tape around bundles of electric wires and exterior members that cover them. For example, Patent Document 1 describes a tape winding device in which a tape supported by a rotating plate that is rotated in a plane perpendicular to the object goes around the object suspended on a central axis of rotation, and the rotating plate is moved relatively along the longitudinal direction of the object, thereby winding tape in a spiral shape around an object such as electric wires.

[0003] Furthermore, Patent Document 2 describes a tape winding device that is equipped with a position regulating member that is arranged close to the side of the rotating plate and regulates the position of the object within the fixed plate notch and the rotating plate notch in order to prevent part of the object from becoming caught between the fixed plate and the rotating plate in the tape winding device.

[0004] The tape winding device includes a fixed plate arranged in a plane perpendicular to the object and a rotating plate arranged adjacent to the fixed plate, which serves as a rotating means for rotating the tape around the object, and the rotating plate is driven to rotate in the plane perpendicular to the object. In order to insert and remove the object onto the central axis of rotation of the tape winding machine, the fixed plate and the rotating plate may be provided with U-shaped notches from the outer periphery toward a central area including the central axis of rotation. In these tape winding machines, the object is inserted and removed when the notch of the fixed plate and the notch of the rotating plate are aligned. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2015-224123 A [Patent Document 2] JP 2019-26440 A Summary of the Invention [Problem to be solved by the invention]

[0006] In tape winding machines equipped with conventional tape winding devices, tension is generated in the tape stretched between the roll tape and the object when winding the tape due to the tape's peeling adhesive force (adhesive force against the non-adhesive surface on the back of the tape itself), and the object is pulled toward the roll tape, so the position of the object is not always stable.If the object is displaced from the central axis of rotation, part of the object may get caught between the fixed plate and the rotating plate, or the wound tape may become significantly wrinkled, making it impossible to wind the tape properly.

[0007] In a tape winding device equipped with a position regulating member, when the notch in the fixed plate and the notch in the rotating plate are aligned and an object is inserted or removed into the deepest part of the notch on the central axis of rotation, the position regulating member retracts to a position that does not interfere with the insertion or removal, and when the rotating plate rotates to wind the tape, the position regulating member must be operated to regulate the position of the object to the deepest part of the notch in the fixed plate and the notch in the rotating plate, which creates the problem that the mechanism and control for this operation make the device complicated.

[0008] The present invention has been made in consideration of the above-mentioned circumstances, and an object of the present invention is to provide a tape winding machine that has a simple mechanism and excellent performance in winding a roll tape. [Means for solving the problem]

[0009] The tape winding machine of the present invention comprises a rotating plate rotated by a motor, the rotating plate having a hollow central region with a notch from the outer periphery to the hollow portion, a fixed plate arranged adjacent to the rotating plate, the rotating plate having a hollow central region with a notch from the outer periphery to the hollow portion, an arm connected to the rotating plate and holding a roll tape with a holder portion at its tip, a support part (rotating) connected to the rotating plate for supporting an object on the rotation central axis, and a support part (fixed) connected to the fixed plate for supporting an object on the rotation central axis.

[0010] In the above-mentioned tape winding machine, the support portion (rotating) and the support portion (fixed) support the object on both sides in the tape width direction of the tape to be wound around the object. Effect of the Invention

[0011] According to the present invention, it is possible to provide a tape winding machine having excellent performance for winding a roll tape, and a tape winding device including the tape winding machine. [Brief description of the drawings]

[0013] The rotating means for rotating and moving the roll tape 2 in a plane perpendicular to the object 1 includes a rotating plate 5 arranged in a plane perpendicular to the object 1 and having a hollow central rotation area, and a fixed plate 6 arranged adjacent to the rotating plate 5 and having a hollow central rotation area, and the rotating plate 5 is driven to rotate by a motor. The rotating plate 5 and the fixed plate 6 are provided with notches for inserting and removing the object 1 from the outer periphery into the hollow central rotation area.

[0014] As shown in Figures 1 and 4, a holder section 3 is provided at the tip of an arm 4 fixed to a rotating plate 5, and holds a rolled tape 2. The rotating plate 5 also has a support section (rotating) 7 that supports an object 1 on the central axis of rotation while rotating. The fixed plate 6 has a support section (fixed) 8 that supports an object on the central axis of rotation.

[0015] The support part (rotating) 7 is provided and connected to the rotating plate 5, and is provided to support the object 1 on the central axis of rotation so that the longitudinal direction of the object is perpendicular to the rotating plate 5. The support part (rotating) 7 has a U-shaped recess that supports the object 1 so that the object 1 is on the central axis of rotation of the rotating plate 5. The opening of the U-shaped recess of the support part (rotating) 7 is provided at an angle that allows the object 1 to be easily inserted and removed through the notch when the notch of the rotating plate 5 and the notch of the fixed plate 6 are aligned.

[0016] The arm 4 is provided connected to the rotating plate 5, and is provided with a holder section 3 at its tip that holds the rolled tape 2. The holder section 3 provided on the arm 4 holds the rolled tape 2 in an angular range in which the object 1 is drawn to the inner side of the U-shaped recess of the support section (rotation) 7 when tension is applied between the object 1 and the rolled tape 2 and the object 1 is drawn toward the rolled tape 2. The angular range in which the object is drawn to the inner side of the U-shaped recess of the support section (rotation) 7 is an angular range in which the angle between the line connecting the center of rotation and the center of the rolled tape 2 is greater than 90 degrees and less than 270 degrees when the opening direction of the support section (rotation) 7 is set to 0 degrees with respect to the central axis of rotation.

[0017] As shown in Figures 6(a) and 6(b), the rotating plate 5 and the fixed plate 6 have a hollow central region including the central axis of rotation, and a notch is provided from the outer periphery to the hollow portion. As shown in Figure 2, the support part (fixed) 8 has a U-shaped recess for supporting the object 1, and is provided connected to the fixed plate so as to support the object 1 on the central axis of rotation. The support part (fixed) 8 can be easily attached and detached, and can be replaced according to the diameter and shape of the object to be supported.

[0018] Support section (fixed) 8 is provided to support object 1 on the central axis of rotation of rotating plate 5 so that the longitudinal direction of the object is perpendicular to the rotation of rotating plate 5. As shown in Fig. 5(a), when the notch of rotating plate 5 and the notch of fixed plate 6 are aligned, object 1 is inserted and removed onto the central axis of rotation through the opening of the notch. Object 1 is supported on the central axis of rotation by support section (rotating) 7 and support section (fixed) 8. EXAMPLES

[0019] The operation of the tape winding machine will be described with reference to Figures 1 to 5. Figure 5 is a schematic diagram showing a rotating plate 5, a fixed plate 6, a support portion (rotating) 7, and a support portion (fixed) 8 which perform the tape winding operation.

[0020] First, the object 1 (such as a bundle of electric wires) is held by the operator's hand or by a device and suspended over the central axis of the rotating plate 5, and is supported by the support part (rotating) 7 and the support part (fixed) 8. At this time, the rotating plate 5 is stopped at a position where the notch of the rotating plate 5 and the notch of the fixed plate 6 are aligned, as shown in Figure 5(a). When the notch of the rotating plate 5 and the notch of the fixed plate 6 are aligned, the object 1 is inserted and removed from the outer periphery of the fixed plate 6 onto the central axis of rotation of the rotating plate 5.

[0021] As shown in Figure 5(a), the end of the roll tape 2 held at the tip of the arm 4 connected to the rotating plate 5 is pulled out and attached to the object 1 supported on the central axis of rotation by a support part (rotating) 7 connected to the rotating plate 5 and a support part (fixed) 8 connected to the fixed plate 6.

[0022] As shown in Figures 3 and 5(b), the rotating plate 5 rotates in the rotation direction 9 upon receiving a driving force from the driving device, and the tape is wound from the roll tape 2 onto the object 1. When the tape stretched from the roll tape 2 to the object 1 is wound onto the object 1, and the tape is pulled out from the roll tape 2 and wound onto the object 1, tension is applied to the tape stretched between the roll tape 2 and the object 1 due to the peeling adhesive force of the tape (adhesive force against the non-adhesive surface on the back side of the tape itself). This tension pulls the object 1 towards the back of the U-shaped recess in the support part (rotating) 7, and the object 1 is supported by the support part (rotating) 7 and the support part (fixed) 8, and is positioned in a central area including the central axis of rotation.

[0023] As shown in Figure 5(c), when the rotating plate 5 rotates in the direction of rotation 9 and the rolled tape 2 is in the opening direction of the notch of the fixed plate 6, the tension applied between the object 1 and the rolled tape 2 by the peeling adhesive force of the tape (adhesive force against the non-adhesive surface on the back side of the tape itself) pulls the object 1 to the back of the U-shaped recess of the support part (rotation), and the object 1 is supported on the rotation axis. This prevents the object from getting caught between the notch of the fixed plate and the notch of the rotating plate, which occurs when the object is displaced from the rotation axis in the opening direction of the fixed plate.

[0024] 1 and 4, the tape winding machine and the target object 1 are moved relative to each other in the moving direction 10 of the longitudinal direction of the target object, thereby winding the tape spirally around the target object 1. At this time, the support part (rotating) 7 and the support part (fixed) 8 support the target object 1 on both sides in the tape width direction, which suppresses displacement of the target object 1 from the central axis of rotation compared to when the target object is supported on one side, allowing for optimal tape winding.

[0025] When the object 1 and the tape winding machine move relative to each other to wind the tape spirally around the object, support section (rotating) 7 and support section (fixed) 8 move in conjunction with the tape winding machine while supporting the object 1 at positions close to both sides in the tape width direction of the tape that is pulled out from the roll tape and wound around the object 1, thereby making it possible to suppress displacement of the object 1 from the central axis of rotation over the entire range in the longitudinal direction of the object where the tape is wound spirally. This mechanism does not require any control or operation such as opening and closing the object position regulating member, and is a simple mechanism that simply provides support sections on the rotating plate and fixed plate, respectively, yet has excellent roll tape winding performance.

[0026] When the tape has finished winding and the rotation of the rotating plate 5 and the relative movement between the object 1 and the rotating plate 5 have stopped, the rotating plate 5 stops at a position where the notch in the rotating plate 5 and the notch in the fixed plate 6 are aligned, as shown in Figure 5(a). In this state, the tape stretched from the roll tape 2 to the object 1 is cut, and the object 1, which is supported on the central axis of rotation by the support part (rotating) 7 and the support part (fixed) 8, is removed through the notch in the rotating plate 5 and the notch in the fixed plate 6.

[0027] As described above, in a tape winding machine in which the roll tape 2 supported by the rotating plate 5 which is driven to rotate in a plane perpendicular to the object 1 winds around the object 1 suspended on the central axis of rotation, and the rotating plate 5 is moved relatively along the longitudinal direction of the object to wind the tape in a spiral shape around the object 1, the support part (rotating) 7 provided on the rotating plate 5 and the support part (fixed) 8 provided on the fixed plate 6 support the object 1 on the central axis of rotation during tape winding, thereby suppressing displacement of the object 1 from the central axis of rotation, and allowing proper tape winding.

In addition, the material, shape, size, and location of each component in the above-mentioned embodiments are arbitrary as long as they can achieve the present invention, and are not limited.

[0029] Furthermore, the object to be wrapped with the tape is not limited to a bundle of electric wires, and any linear material that can be wrapped with the tape can be used in the present invention. For example, it may be a single electric wire, a linear member that does not include an electric wire, or a tubular material. [Explanation of symbols]
