Description

The present invention relates to a tape winding device capable of winding adhesive tape around the outer periphery of objects to be bound.

In the process of manufacturing wire harnesses installed in automobiles, etc., there is a process of wrapping multiple electric wires with adhesive tape and bundling them together. Here, a bundle of electric wires is sometimes covered with a corrugated tube and wrapped together with tape, so hereinafter, the object to be wrapped with tape is referred to as the object to be bound.

Conventionally, when performing this type of tape winding process, the tape reel (tape roll) wound with adhesive tape is rotated around the object to be bound, and while the adhesive tape is peeled off from the tape reel, the outer circumference of the object to be bound is It was done by wrapping it around.

However, when rotating the entire tape reel, the rotating body becomes large, making it difficult to wind the tape in a narrow working space. Therefore, the tape reel is fixedly installed in the device body separately from the rotating body (hereinafter referred to as the rotating drum), and the adhesive tape is sent out from the fixedly installed tape reel, and the adhesive tape is rotated. A device has been developed that rotates a drum and wraps it around objects to be bound (for example, see Patent Document 1). Note that "feeding out the adhesive tape" refers to sequentially and continuously feeding out the adhesive tape wound around the tape reel from its tip.

The tape winding device described in Patent Document 1 includes a tape reel holding section, a rotating drum, and a tape feeding device. The rotating drum wraps adhesive tape around the outer periphery of the object to be bound by rotating around the object to be bound arranged in its internal space. Further, the tape feeding mechanism sequentially feeds out the adhesive tape from a fixedly provided tape reel toward the internal space of the rotating drum. The rotating drum is provided with an opening for introducing the adhesive tape and the objects to be bound, which are fed out by the tape feeding mechanism, into the internal space of the rotating drum.

Generally, the adhesive tape used for this type of application is a single-sided adhesive tape having an adhesive material on one side, and is rolled while being attached to the outer periphery of the object to be bound, with the adhesive side facing the inner surface. The surface opposite to the adhesive surface of the single-sided adhesive tape is a non-adhesive surface, and is provided with releasability as required.

According to this tape winding device, the adhesive tape is attached to the outer periphery of the object to be bound by rotating the rotating drum while the tip of the adhesive tape is stuck to the outer periphery of the object to be bound in the internal space of the rotating drum. You can wrap it around while doing so.

Japanese Patent Application Publication No. 2008-168925

By the way, when automating the tape winding process using, for example, the above-mentioned tape winding device, it is difficult to wind the adhesive tape around a loose object to be bound while maintaining the horizontal and vertical state. Therefore, due to the tension related to the adhesive tape, the adhesive tape is likely to be misaligned in the width direction of the adhesive tape, which may result in poor wrapping of the adhesive tape. In addition, misaligned adhesive tape is likely to get caught in gaps within the tape winding device, such as the gap between both end faces of the rotating drum in the direction of its rotational axis and the frame that holds the rotating drum, which may cause device failure. . Furthermore, even when an operator winds the tape with tape, there is a risk that the adhesive tape may be wrapped incorrectly or the tape may enter the tape winding device, causing equipment failure. As described above, in the tape winding device described above, problems may occur during the tape winding process.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a tape winding device that can reduce problems in the tape winding process.

In order to achieve the above-mentioned object, the tape winding device according to the present invention has the following features.

a rotating drum that covers at least a portion of the outer periphery of the object to be bound and rotates around the object to be bound, which is disposed in an internal space;
a holding part that rotatably holds the rotating drum;
The holding section includes a support section that supports a tape reel around which adhesive tape is wound;
a supply unit that supplies the adhesive tape to the rotating drum;
The rotating drum is
a first opening for introducing the objects to be bundled into the internal space;
a second opening for introducing the adhesive tape to be wrapped around the object to be bundled from the supply section into the internal space;
The second opening includes side guides that cover both edges of the adhesive tape in the width direction.

Specific embodiments of the present invention will be described below with reference to each figure.

FIG. 1 is a schematic side view of a tape winding device according to an embodiment of the present invention, and FIG. 2 is a schematic perspective view showing the main part configuration of the tape winding device.

As shown in FIGS. 1 and 2, in this tape winding device 5, a tape reel 100 around which adhesive tape 1 is wound wraps around an object W to be bundled (here, a bundle of a plurality of electric wires as shown). In this type, the adhesive tape 1 is wound around the object W to be bound by rotating only the rotary drum 10 without rotating. That is, the tape reel 100 is not installed on the rotating drum 10 which is a rotating body, but is fixedly provided on the frame 20 separately from the rotating drum 10.

<Adhesive tape 1>
The adhesive tape 1 used here is a general single-sided adhesive tape with adhesive material provided on only one side, and is wound into a roll with the adhesive side 1a on the inside and the non-adhesive side 1b on the outside. The tape reel 100 is used for tape winding work. In the tape reel 100, the adhesive surface 1a of the upper layer tape is in contact with the non-adhesive surface 1b of the lower layer tape (a release layer may be provided on this non-adhesive surface), and the adhesive tape 1 can be easily removed from the tip. It is now possible to take it out.

<Main elements of tape winding device>
The tape winding device 5 of this embodiment includes a rotating drum 10, a tape reel support section 21, a tape feeding mechanism 22 (supply section), a tape cutter 30, etc., and these elements are connected to a frame 20 (which is the main body of the device). (holding part). The frame 20 is then attached to the arm of an industrial robot as needed, so that it can be automatically moved relative to the objects W to be bundled supported by a jig plate or the like.

The rotating drum 10 is supported by a frame 20 so as to rotate about the axial center line of the objects W to be bound W introduced into the internal space 15 as a rotation center O. The internal space 15 of the rotating drum 10 is provided in a range that includes the rotation center O. The tape reel 100 is rotatably supported by a tape reel support section 21 on a frame 20 located at a different position from the rotating drum 10. Further, the tape feeding mechanism 22 is arranged between the rotating drum 10 and the tape reel 100.

The rotating drum 10 wraps the adhesive tape 1 around the outer periphery of the binding object W by rotating around the binding object W arranged in the internal space 15. The tape feeding mechanism 22 feeds out the adhesive tape 1 wound around the tape reel 100 toward the rotating drum 10. The tape feeding mechanism 22 also includes a roller set 22a disposed just before the rotating drum 10. In FIG. 1, the feeding direction of the adhesive tape 1 is indicated by an arrow A. A tape cutter 30 (tape cutting means) for cutting the adhesive tape 1 is provided near the roller set 22a. The tape cutter 30 cuts the adhesive tape 1 under tension by protruding from a retracted position where it does not touch the adhesive tape 1 to a cutting position where it touches the adhesive tape 1.

<Rotating drum 10>
The rotating drum 10 has a cylindrical shape, and has a first opening 11 in its peripheral wall for introducing the objects W to be bound into the internal space 15 and an adhesive tape 1 fed out by a tape feeding mechanism 22 into the internal space 15. A second opening 12 is provided. The first opening 11 and the second opening 12 are provided on opposite sides of the rotation center O, respectively.

The first opening 11 is an opening for introducing the binding object W extending in the longitudinal direction, and is open to both ends of the rotating drum 10 in the axial direction. On the other hand, the second opening 12 is for introducing the adhesive tape 1 of a certain width, and at least one end of the rotary drum 10 in the axial direction is closed with some kind of member (such as a gear to be described later).

The rotating drum 10 is rotatably supported by a frame 20 by a plurality of rollers 17 arranged around the outer periphery without having a substantial rotation axis. The rotating drum 10 is integrally provided with a ring-shaped gear (not shown) for rotating the rotating drum 10. This gear is one element of a drive mechanism for rotationally driving the rotating drum 10. This gear is not a continuous ring, but has a notch at a position corresponding to the first opening 11 of the rotating drum 10 so as not to obstruct the introduction of the objects W to be bundled into the rotating drum 10. The rotating drum 10 is rotationally driven in one specific direction by applying rotational force to this gear. In FIG. 1, the direction of rotation of the rotating drum 10 is indicated by an arrow B.

<Direction of adhesive surface 1a of adhesive tape 1>
When the adhesive tape 1 enters the second opening 12 of the rotating drum 10, the adhesive surface 1a is moved in the direction of movement of the second opening 12 (rightward in FIG. 1) due to the rotation of the rotating drum 10 in the direction of arrow B. The paper is fed into the rotating drum 10 in a facing attitude (with the adhesive surface 1a facing right). Therefore, as the rotating drum 10 rotates in the direction of arrow B, the adhesive tape 1 brings its non-adhesive surface 1b into contact with the side surface 12a (see FIG. 2) of the second opening 12 on the rear side in the rotational direction. It is brought into contact with the outer peripheral surface of the rotating drum 10.

That is, when the adhesive tape 1 is drawn toward the rotating drum 10 along the outer periphery of the rotating drum 10 as the rotating drum 10 rotates, the adhesive surface 1a of the adhesive tape 1 covers the radially outer side of the rotating drum 10. It will be facing towards you. A plurality of rollers 17 that rotatably support the rotating drum 10 are in contact with the outer periphery of the rotating drum 10, and these rollers 17 have a structure that allows them to easily peel off even if they come into contact with the adhesive surface 1a of the adhesive tape 1. has been done. Therefore, the rotation of the rotating drum 10 is not inhibited, and the adhesive tape 1 drawn along the outer periphery of the rotating drum 10 is not particularly affected.

<Holding roller 50>
Further, the second opening 12 for tape introduction of the rotating drum 10 is provided with a holding roller 50 that holds the adhesive tape 1 introduced from the second opening 12 into the internal space 15. This holding roller 50 is attached to a side surface 12b (see FIG. 2, right side in FIG. 1) on the front side in the rotational direction (direction of arrow B) of the second opening 12 of the rotating drum 10. It is provided so that it can move forward and backward toward the side surface 12a (see FIG. 2; the left side surface in FIG. 1). Then, the holding roller 50 can press and hold the adhesive tape 1 against the rear side surface 12a of the second opening 12 in the rotational direction while moving forward toward the rear side surface 12a of the second opening 12 in the rotational direction. It looks like this.

This holding roller 50 is a one-way roller that rotates only in one direction and is prevented from rotating in the opposite direction. The direction in which rotation is allowed is the direction in which the adhesive tape 1 introduced into the second opening 12 is sent out further toward the internal space 15. That is, the holding roller 50 is provided to allow the adhesive tape 1 to move forward in the direction of the object W to be bound, but not to move backward in the direction of the tape feeding mechanism 22. In FIG. 1, the direction of arrow C1 is the direction in which rotation is allowed (○ mark), and the direction of arrow C2 is the direction in which rotation is restricted (mark x).

The holding roller 50 is controlled in its forward and backward movement (advancing to the position where the adhesive tape 1 is pressed and retreating to the retracted position) by a drive mechanism such as an air cylinder (not shown). Furthermore, when the holding roller 50 advances to the pressing position, it can apply a biasing force to the adhesive tape 1 by a biasing means 55 such as an air cylinder.

<Side tape guide 60>
Further, the second opening 12 of the rotating drum 10 is provided with side tape guides 60 (side guides) that cover both edges in the width direction of the adhesive tape 1 to be introduced and regulate the position of the adhesive tape 1 in the width direction. It is being This side tape guide 60 is a frame body equipped with a pair of regulating wall surfaces located on both sides of the adhesive tape 1 in the width direction, and can be installed in the second opening 12 of the rotating drum 10 as a post-installation. There is. The side tape guide 60 can prevent the adhesive tape 1 from entering gaps in the tape winding device 5, such as gaps between the frame 20 and both end surfaces of the rotating drum 10 in the direction of the rotation axis, when the rotating drum 10 rotates.

<Cushion member 70>
A cushion member 70 (elastic body) made of an elastic material such as sponge or urethane is provided in the range from the second opening 12 of the rotating drum 10 to the central region of the internal space 15. The cushion member 70 is a guide member for elastically pressing the adhesive surface 1a of the adhesive tape 1 introduced from the second opening 12 against the binding object W introduced into the internal space 15 of the rotating drum 10. It is.

As shown in FIG. 2, this cushion member 70 extends from a side surface 12a on the rear side in the rotation direction of the second opening 12 to a side surface 11a on the front side in the rotation direction of the first opening 11 on the opposite side. 10. The cushion member 70 has a shape in which an inclined guide surface 70a is directed at a distance from the center of rotation O of the rotating drum 10. The inclined guide surface 70a is inclined so as to approach the rotation center O of the rotary drum 10 as it goes from the entrance side of the second opening 12 to the back side, and the inclined guide surface 70a approaches the rotation center O of the rotating drum 10 from the entrance side of the second opening 12. It is curved in an arc.

The presence of this cushion member 70 allows the adhesive surface 1a of the adhesive tape 1 to be pressed against the object W introduced into the internal space 15 of the rotating drum 10 in an appropriate positional relationship. That is, by the cushion member 70 pressing the adhesive tape 1 onto the object W to be bound, the tape winding device 5 can move the object W to be bundled while keeping the position W of the object W close to the center of rotation O of the rotary drum 10. The adhesive tape 1 can be wrapped around the object W. Therefore, according to this tape winding device 5, it is possible to prevent the positional shift of the binding object W due to bending or vibration, and further improve the winding accuracy of the adhesive tape 1. Note that the cushion member 70 is preferably made of a material that does not easily generate static electricity between it and the adhesive tape 1. Further, the shape and softness of the cushion member 70 are preferably selected according to the cross-sectional shape, cross-sectional size, etc. of the objects W to be bundled. For example, a bundle of electric wires as the object W to be bundled has many irregularities on the outer periphery, so a material with high elasticity allows the adhesive tape 1 to be in close contact with the electric wires with a wide contact area. In the case of thin wires, it is preferable to choose a material that is somewhat hard.

<Resin sheet piece 72>
On the first opening 11 side of the rotating drum 10, there is a flexible resin sheet piece 72 (tape end holding section) that holds the tip of the adhesive tape 1 introduced into the internal space 15 through the second opening 12. ) is provided. The resin sheet piece 72 restricts the position of the tip of the adhesive tape 1 introduced into the internal space 15, and also restricts the position of the binding object W introduced from the first opening 11 so that it does not fall off. This resin sheet piece 72 is provided as a spring piece whose base end is fixed to the entrance side of the first opening 11 of the semicircular arc-shaped portion of the cushion member 70, and the free tip 72a is attached to the first opening 11. (the rear side surface 11b in the rotational direction of the rotating drum 10).

When introducing the binding object W from the first opening 11, the resin sheet piece 72 allows easy introduction because the free end 72a extends obliquely along the introduction direction. However, when the object W to be bound is about to come out from the internal space 15, the direction in which the free end 72a extends diagonally is the opposite direction to the escape direction, so that the resin sheet piece 72 can easily remove the object W to be bound. It functions to prevent escape. Note that when the objects W to be bound W are led out of the rotating drum 10 after the wrapping of the adhesive tape 1 is finished, the removal is performed with a stronger force, so the resin sheet pieces 72 are elastically deformed and the objects W to be bound are This does not hinder the derivation of W. This resin sheet piece 72 makes it easy to introduce the objects W to be bound into the internal space 15 of the rotary drum 10, makes it difficult for the objects W to escape while the rotary drum 10 is rotating, and makes it difficult to remove the objects W to be bound while the rotary drum 10 is rotating. It is preferable to decide the length, angle, material, etc., taking into account the ease with which the objects W to be bound can be taken out from the rotating drum 10.

<Operation and action>
Next, the operation and effect will be explained.
FIGS. 1 and 3 to 9 are explanatory diagrams sequentially showing operations during tape winding.

First, as shown by arrow A in FIG. 1, the adhesive tape 1 is fed out from the tape reel 100 without introducing the object W to be bound into the rotating drum 10. At this time, the rotating drum 10 is at an initial position with the second opening 12 facing in a direction in which it can receive the tip of the adhesive tape 1 that has been sent out, and is not rotating. The tip of the adhesive tape 1 that has been sent out is introduced into the internal space 15 of the rotating drum 10 from the second opening 12, and as shown in FIG. 3, while being guided by the guide surface 70a (FIG. 2) of the cushion member 70, When it hits the resin sheet piece 72 or reaches the vicinity thereof, the tape stops when the tape feed is stopped. When introducing the adhesive tape 1, the side tape guide 60 regulates the position of the adhesive tape 1 in the width direction.

Next, at that stage, as shown in FIG. 4, the holding roller 50 incorporated in the rotating drum 10 moves forward in the direction of arrow D1 and presses the adhesive tape 1 against the wall of the second opening 12. Due to this pressing by the holding roller 50, the adhesive tape 1 is held within the rotating drum 10 so that it can move forward in the feeding direction but cannot move back in the opposite direction.

Next, as shown in FIG. 5, by moving the tape winding device 5 itself in the direction of the arrow E1, the objects W to be bound are guided into the internal space 15 of the rotary drum 10 from the first opening 11 of the rotary drum 10. . Relative movement of the binding object W with respect to the tape winding device 5 is indicated by an arrow e1. At this time, the resin sheet piece 72 allows the objects W to be bound to be introduced into the rotating drum 10 while being flexibly and elastically deformed. By introducing the objects W to be bound into the internal space 15 of the rotating drum 10 in this manner, the adhesive surface 1a at the tip of the adhesive tape 1 sticks to the outer periphery of the objects W to be bound. Depending on how the tape winding device 5 is moved with respect to the object W to be bound, the adhesion of the adhesive surface 1a of the adhesive tape 1 can be promoted.

Next, as shown in FIG. 6, the rotating drum 10 is rotated in the direction of arrow B. At the same time, the tape feeding mechanism 22 feeds out the adhesive tape 1 wound around the tape reel 100 toward the rotating drum 10. When the rotating drum 10 rotates around the objects W to be bound W arranged near its rotation center O (FIG. 1), the adhesive tapes 1 are wound around the outer periphery of the objects W to be bound one after another. At the same time, the adhesive tape 1 fed out by the tape feeding mechanism 22 is continuously drawn in along the outer periphery of the rotating drum 10.

At this time, since the holding roller 50 reliably holds the adhesive tape 1 introduced into the rotating drum 10 in a state where it can move forward in the second opening 12 but cannot move backward, the adhesive tape 1 introduced into the rotating drum 10 The adhesive tape 1 is not pulled back to the outer circumferential side of the rotating drum 10.

When the rotary drum 10 has rotated by a predetermined amount (necessary tape winding amount) and feeding of the adhesive tape 1 has been completed, the tape cutter 30 projects as shown by arrow F and the adhesive tape 1 is cut at that position. This means that the required length of adhesive tape 1 has been supplied to the rotating drum 10.

As shown in FIG. 7, as the rotating drum 10 further rotates, the adhesive tape 1 drawn in along the outer circumference of the rotating drum 10 is moved inside the rotating drum 10 while its position in the width direction is regulated by the side tape guides 60. It is pulled in and wrapped around the outer periphery of the object W to be bound.

When all of the cut adhesive tape 1 is wrapped around the outer periphery of the object to be bound W and the rotating drum 10 returns to the initial position as shown in FIG. 8, the tape winding device 5 itself moves (moves upward in the figure), and the bound object W, which has been wrapped with tape, is led out of the rotating drum 10. The movement of the tape winding device 5 at this time is shown by an arrow E1, and the relative movement of the object W to be bound with respect to the tape winding device 5 is shown by an arrow e2. Further, before and after this movement, the holding roller 50 retreats to the retracted position as shown by arrow D2, and transitions to a state of preparation for the next winding operation.

All of the above operations are performed while the timing, speed, etc. are controlled by the functions of a servo mechanism and a control mechanism (not shown), and by the functions of a robot equipped with a tape winding device.

As explained above, according to the tape winding device 5 of the embodiment, the holding roller 50 holds the adhesive tape 1 introduced into the rotating drum 10 so that it cannot be pulled back, and the holding roller 50 holds the adhesive tape 1 introduced into the rotating drum 10 so that it cannot be pulled back. rotate around. Therefore, even if the tip of the adhesive tape 1 is not strongly attached to the outer periphery of the object W to be bound, it is possible to eliminate a mistake in which the adhesive tape 1 is not fed out as the rotary drum 10 rotates. As a result, it is possible to prevent the phenomenon that the adhesive tape 1 does not wrap around the object W to be bound (defective tape winding) and the tape jam. In particular, when the number of wires to be bundled is small, the tip of the adhesive tape 1 tends to not stick to the wires reliably, but even in such cases, mistakes in feeding the tape can be prevented. Therefore, poor tape winding and tape clogging can be suppressed.

Further, the holding roller 50 is movable toward and away from the second opening 12 of the rotating drum 10 and is provided so as to protrude into the second opening 12 only when the rotating drum 10 is rotating. It does not interfere with the behavior of the tape 1. Moreover, since the holding roller 50 is equipped to exert a biasing force against the adhesive tape 1, the pressing force against the adhesive tape 1 can be maintained appropriately.

Further, in the tape winding device 5 of this embodiment, since the cushion member 70 is provided inside the rotating drum 10, it is possible to promote adhesion of the adhesive surface 1a of the adhesive tape 1 to the object W to be bound. Further, since the resin sheet piece 72 is provided on the first opening 11 side of the rotating drum 10, the tip of the adhesive tape 1 is held by the resin sheet piece 72, and the objects W to be bound are held on the adhesive surface 1a of the adhesive tape 1. It can be introduced into the internal space 15 within the rotating drum 10 without coming into contact with the rotating drum 10. Therefore, the accuracy of wrapping the adhesive tape around the object W to be bound can be improved. Furthermore, since the resin sheet pieces 72 hold the objects W to be bound, the objects W to be bound once accommodated in the rotating drum 10 can be prevented from falling out while the rotating drum 10 is rotating.

In addition, in the tape winding device 5 of this embodiment, since the side tape guide 60 is provided in the second opening 12 of the rotary drum 10, the adhesive tape 1 fed into the rotary drum 10 may be misaligned in the width direction. This prevents it from getting into gaps in the device. Further, even if the object to be bound W is bent or its attitude with respect to the device is tilted, it is possible to prevent the position of the adhesive tape 1 from shifting due to being dragged by it. Therefore, it is possible to prevent the adhesive tape 1 from shifting from its proper position as it is wound (shifting of the tape winding position).

Furthermore, since the tape winding device 5 of this embodiment is not of a type in which the tape reel 100 is rotated together with the rotating drum 10, the rotating portion can be downsized. Therefore, it is useful for wrapping tape around narrow parts such as branching parts of wire harnesses, and can contribute to expanding the range of automation.

Note that the present invention is not limited to the embodiments described above, and can be modified, improved, etc. as appropriate. In addition, the material, shape, size, number, arrangement location, etc. of each component in the above-described embodiments are arbitrary as long as the present invention can be achieved, and are not limited.

Here, the features of the tape winding device according to the embodiment of the present invention described above will be briefly summarized and listed below in [1] to [2].

The rotating drum (10) is
a first opening (11) for introducing the objects to be bundled into the internal space;

Tape winding device (5).

According to the tape winding device 5 described in [1] above, the side tape guides 60 cover both widthwise edges of the adhesive tape 1 in the second opening 12, so that the widthwise position of the adhesive tape 1 can be adjusted. Regulated. Therefore, it is possible to prevent the adhesive tape 1 from entering the gap within the tape winding device 5, thereby preventing device failure due to the adhesive tape entering into the device. Further, according to the tape winding device 5, the position of the adhesive tape 1 in the width direction can be controlled to prevent the tape winding position from shifting, so that poor winding of the adhesive tape 1 can be reduced. In this way, according to the tape winding device 5, problems in the tape winding process can be reduced whether the winding process is manual or automatic.

Furthermore, even when the tape winding device 5 described in [1] above is used to automatically wind tape around loose wires to be bundled, misalignment of the adhesive tape 1 in the width direction can be avoided. This can be prevented by the side tape guide 60. Therefore, according to this tape winding device 5, it is possible to reduce problems in the tape winding process such as poor tape winding and device failure due to tape entering the device, thereby improving the accuracy of tape winding automation.

If a guide were to be provided in the main body of the rotating drum 10, that is, in the portion of the rotating drum 10 excluding the first opening 11 and the second opening 12, the width of the rotating drum main body would increase, and the device size would increase. Put it away. On the other hand, according to the tape winding device 5, since the side tape guide 60 is provided in the second opening 12 of the rotary drum 10, the position of the adhesive tape 1 in the width direction can be controlled with a compact structure.
