By the tension applied between the tape 1 and the target object 9, the roll tape 1 held by the arm 3 moves toward the target object 9, so that the pressing portion 8 provided on the arm 3 causes the roll tape 1 and the target object 9 to move. The tape winding position of the object in the longitudinal direction is regulated while pressing the tape stretched between the objects 9. [Selection diagram] Fig. 3

Description

The present invention relates to a tape winding machine that winds a roll tape around an object such as an electric wire bundle.

BACKGROUND ART Conventionally, as a part of manufacturing a wire harness for a vehicle, a tape winding device that winds a tape around an electric wire bundle or an exterior member that covers the electric wire bundle has been proposed. The tape wrapping machine equipped with this tape wrapping device has a tape supported on a rotating plate that rotates in a plane orthogonal to the object, and rotates around the object around the center axis of rotation. , Tape is wrapped around an object such as an electric wire.

The tape winding device includes a fixed plate arranged in a plane orthogonal to the object as a turning means for rotating the tape around the object and a rotating plate arranged adjacent to the object. It is rotationally driven in a plane orthogonal to each other.

In order to insert/remove an object on/from the central axis of rotation of the tape winding machine, a U-shaped cutout may be provided on the fixed plate and the rotary plate from the outer peripheral edge toward the central region including the central axis. .. In these tape winding machines, the target is inserted and removed with the notch of the fixed plate and the notch of the rotating plate aligned.

With a tape winding machine equipped with a conventional tape winding device, at the start of tape winding, the end of the roll tape is pulled out and the tape is attached to the target object, but the adhesive area is small because the adhesive area between the tape and the target object is small. When the tape starts to be wound around the object due to lack of tape, the peeling adhesive force of the tape (adhesion to the non-adhesive surface on the back of the tape itself) causes the tension generated on the tape stretched between the roll tape and the object. The strength of the tape sometimes caused the tape to come off (separate) from the object.

The tape wrapping strength of the conventional tape wrapping machine equipped with the tape wrapping device depends on the peeling adhesive strength of the tape (adhesive strength to the non-adhesive surface on the back surface of the tape) between the roll tape and the object. Depending on the tension applied to the stretched tape, depending on the target object (electric wire bundle or exterior member that covers it), the tape may be wound around the target object loosely and a gap may be created between the wound tapes. There was a case where an appropriate fixing force could not be obtained on the object. Further, there are cases in which wrinkles are formed on the wound tape, and suitable winding cannot be performed.

The tape winding machine included in the conventional tape winding device may not be able to accurately wind the tape around the limited area of the object.

The present invention has been made in view of the above-mentioned circumstances, and an object thereof is to provide a tape winding machine having excellent winding performance for a roll tape.

Holding the roll tape on the arm connected to the rotating plate by the rotating shaft, the rotating plate rotates, and when the tape is wound around the object from the roll tape, by the tension applied between the roll tape and the object, By moving the roll tape held by the arm in the direction of the target object, the tension applied between the roll tape and the target object is suppressed, and the tape end part attached to the target object comes off (separates) from the target object. ) Is suppressed. Further, by moving the roll tape held by the arm toward the target object, the pressing portion provided on the arm presses the tape stretched between the roll tape and the target object, thereby wrinkling the tape. Wrap the tape tightly around the object while restraining it.

The tape position regulation unit provided in the pressing unit regulates the position of the tape stretched from the roll tape to the object in the tape width direction, so that the tape is wound on the accurate position in the longitudinal direction of the object.

According to the present invention, it is possible to provide a tape winding machine having an excellent winding performance for a roll tape, and a tape winding apparatus equipped with the tape winding machine.

FIG. 1 is a perspective view of a tape winding machine according to the present invention. FIG. 2 is a perspective view showing the operation of winding the tape. FIG. 3A is a schematic view showing the operation of starting winding the tape. FIG. 3B is a schematic view showing the operation of winding the tape. FIG. 3C is a schematic view showing a state where the tape has been wound.

As shown in FIG. 1, a holder 2 is provided at the tip of an arm 3 connected by a rotary shaft 4 fixed to a rotary plate 5 to hold a roll tape 1 (adhesive tape). The arm 3 is provided with a pressing portion 8.

As shown in FIG. 1, the pressing portion 8 is provided with a U-shaped notch as a tape position regulating portion, and as shown in FIG. 2, the pressing portion 8 is stretched from the roll tape to the object. When the back surface of the tape is pressed, it has a shape that regulates the position of the tape in the width direction.

The rotating shaft 4 has a holding force that does not rotate due to the weight of the roll tape 1, the holder portion 2, the arm 3, and the pressing portion 8, and is a tape stretched from the roll tape 1 to the target object 9. When the tape is wound around the object 9 and a tension is applied between the roll tape 1 and the object 9, the holding force is within a range in which the tape is not pulled out from the roll tape 1 and the arm 3 easily rotates.

The rotation range of the arm 3 is regulated in the rotation inward direction by the rotation regulation section 7 within a range in which the arm 3 and the pressing portion 8 provided in the arm 3 do not press the object 9. In the outward rotation direction, the center of the roll tape 1 is regulated within a range that does not exceed the extension of the line connecting the center of rotation and the center of the rotating shaft 4.

The operation of the tape winding machine will be described with reference to FIGS. FIG. 3 is a schematic view showing the rotary plate 5, the arm 3, and the pressing portion 8 which perform the tape winding operation.

First, the object 9 (a bundle of electric wires or the like) is held by an operator's hand or a device and bridged over the rotation center axis of the rotation plate 5. At this time, as shown in FIG. 1, the pressing portion 8 retracts the arm 3 to the position that does not interfere with the operation of stretching the tape from the roll tape 1 to the target object 9 by rotating the arm 3 in the rotation outward direction. There is.

The tape end of the roll tape 1 held at the tip of the arm 3 connected to the rotary plate 5 by the rotary shaft 4 is pulled out and attached to the object 9.

As shown in FIG. 3( a ), the rotating plate 5 starts to rotate in the direction of rotation 10 in response to the driving force from the driving device, so that the tape stretched from the roll tape 1 to the object 9 is the object. It is wound around 9, and tension is applied between the roll tape 1 and the object 9. Since the holding force of the rotating shaft 4 connecting the rotating plate 5 and the arm 3 is smaller than the peeling adhesive force of the tape (adhesive force to the non-adhesive surface on the back surface of the tape itself), the tape can be rotated without being pulled out. The arm 3 rotates about the moving shaft 4 in a rotation direction 11 (inward rotation direction), which is a direction in which the roll tape 1 approaches the object 9. At this time, since the tape is wound without pulling it out from the roll tape 1, the tension applied between the roll tape 1 and the target object 9 is suppressed, so that the tape is loosely wound around the target object 9 and attached to the target object 9. The attached tape end is prevented from coming off (separating) from the object 9.

When the rotary plate 5 rotates in the direction of rotation 10, the arm 3 rotates in the direction of rotation 11, and the pressing portion 8 provided on the arm 3 moves between the roll tape 1 and the object 9. Press the back surface (non-adhesive surface) of the stretched tape. At this time, the position of the tape stretched between the roll tape 1 and the object 9 in the width direction is regulated by the U-shaped notch provided in the pressing portion 8, so that the length of the object 9 is increased. The tape winding position in the direction is restricted.

Also, when the pressing portion 8 provided on the arm 3 presses the back surface (non-adhesive surface) of the tape stretched between the roll tape 1 and the target object 9, it is pressed between the roll tape 1 and the target object 9. In addition to the tension due to the peeling adhesive force of the tape (adhesive force to the non-adhesive surface on the back surface of the tape itself), the pressing force of the pressing portion 8 and the friction force of the pressing portion 8 are applied to the tape stretched. At this time, the tape is wound around the object 9 more strongly than when it is wound only by the tension due to the peeling adhesive force.

As shown in FIGS. 2 and 3B, during the tape winding operation, the tape stretched from the roll tape 1 to the object 9 is rotated by the rotating plate 5 in the direction of rotation 10 so that the object is the object. It is wound around 9, and tension is applied between the roll tape 1 and the object 9. The arm 3 is held by the arm 3 because the rotation restricting portion 7 provided on the rotating body restricts the rotation of the arm 3 within a range in which the arm 3 and the pressing portion 8 provided on the arm 3 do not press the object 9. The rolled tape 1 is held while being restricted from moving inward. Since the roll tape 1 does not move inward in rotation, the tape is wound around the object 9 while being pulled out from the roll tape 1 by the tension of the tape.

When the rotating plate 5 is rotating, a tension is applied between the roll tape 1 and the object 9 by the tape peeling adhesive force (adhesive force to the non-adhesive surface on the back surface of the tape). 3 is kept at a position where the pressing portion 8 presses the back surface of the tape stretched between the roll tape 1 and the object 9. At this time, the tape is wound around the object 9 more strongly than when it is wound only by the tension due to the peeling adhesive force. In addition, pressing the back surface of the tape suppresses the occurrence of wrinkles on the tape. Further, the U-shaped notch provided in the pressing portion 8 regulates the position of the tape stretched from the roll tape 1 to the object 9 in the tape width direction, so that the longitudinal direction of the object 9 is reduced. The tape winding position is regulated and the tape is wound at the correct position.

As shown in FIG. 3C, when the tape is completely wound and the rotating plate 5 is stopped, the tape is not pulled out due to the peeling adhesive force of the roll tape 1 (adhesive force to the non-adhesive surface on the back surface of the tape itself). , The arm 3 is kept at a position where the rotation inward is restricted.

The tape stretched from the roll tape 1 to the object 9 is cut, and the object 9 is removed from the tape winding machine. At this time, the arm 3 can easily rotate within a restricted range.

As described above, when the tape is wound, the pressing portion 8 provided on the arm 3 presses the back surface of the tape stretched between the roll tape 1 and the target object 9, so that the tape is limited to the target object 9. A strong wrap is made at a precise position in the open area to provide a suitable wrap.

The present invention is not limited to the above-mentioned embodiments, and various modifications can be adopted within the scope of the present invention. In addition, the materials, shapes, dimensions, locations, etc. of the constituent elements in the above-described embodiments are arbitrary and are not limited as long as the present invention can be achieved.

The pressing portion of the present invention is not limited to the above embodiment, and various modifications can be adopted within the scope of the present invention. For example, it is a columnar shape with steps.

Further, the position of winding the tape is not limited to the overlapping winding at the same position, but the tape winding machine and the object are moved relative to each other along the central axis of rotation, so that the tape can be accurately placed in the limited area of the object. Can be wound in a spiral.

Further, the object on which the tape is wound is not limited to the electric wire bundle, and any linear material around which the tape is wound 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 tube-shaped material.
