The pressure-sensitive adhesive tape 72 is suspended by its own weight from the guide roller 76 to the lower side of the opening 78 through the inclined surface 77a.

  In this state, as shown in FIG. 10B, a plurality of bundle-shaped electric wires 81 are inserted into the notch 79 of the rotary drum 80 from the opening 78 together with the adhesive tape 72, and the rotary drum 80 is rotated as indicated by the arrow by the drive mechanism. At the initial stage, the adhesive tape 72 is cut by the cutter 82, and the adhesive tape 72 is wound around the outer periphery of the electric wire 81 by the rotation of the rotary drum 80.

  The drive mechanism includes an upper and lower rack 83, gears on the outer periphery of the rotating drum engaged with the rack 83, a guide hole 84 for moving the rack 83 up and down, and an air cylinder 85 for moving the rotating drum 80 back and forth. .

  Fig.11 (a) shows the other form of the conventional adhesive tape drooping mechanism and a tape winding apparatus provided with the same (refer patent document 2).

  The tape winding device 50 supplies a rotary drum 57 having a notch 61, a drive mechanism 58 for rotating the rotary drum 57, tape cutting mechanisms 59 and 60, and an adhesive tape 54 to the rotary drum side via the tape cutting mechanism. And a supply mechanism 52 that is installed.

JP 62-215467 A (FIG. 1) JP-A-9-183413 (FIG. 6)

  However, in the conventional tape winding device 71 having the adhesive tape drooping mechanism shown in FIG. 10, the case where the adhesive tape 72 suspended from the opening 78 of the rotary drum 80 is rolled up due to the influence of wind or the movement of the device. 77, etc., and the adhesive tapes 72 are easily adhered to each other. In this case, the operator must release the adhesive tape 72 one by one, and the tape winding workability is lowered. There were problems that the winding became dirty and the adhesive strength decreased. The same applies to the tape winding device 50 shown in FIG. 11 in which the adhesive tape 54 is supplied vertically hanging down.

  In order to prevent the adhesive tapes 72 and 54 from rolling up, it is only possible to use a hard adhesive tape, and in order to prevent sticking of the tapes other than that, for example, the case portion 77 on the upper side of the opening of the rotary drum 80 has an uneven shape. In some cases, a non-adhesive plate-like member (not shown) is provided, but even in that case, the tape winding device can be used horizontally or downward in order to hang the adhesive tape 72 under its own weight. It could not be used at an angle. The only way to use the tape winding device at an angle was to use an adhesive tape that was stiff and difficult to change.

  These problems can occur in the same manner even when a corrugated tube (harness protection tube) that covers the electric wires, a wire body other than the electric wires, or the like is used as a bound body instead of the electric wires 81 and 63.

In view of the above-described points, the present invention can prevent inadvertent sticking of the hanging portion of the adhesive tape without limiting the type of the adhesive tape, and can be used even when tilted obliquely. and to provide a tape winding equipment having a pressure-sensitive adhesive tape droop Organization.

In order to achieve the above object, a tape winding apparatus having an adhesive tape drooping mechanism according to claim 1 of the present invention supplies an adhesive tape that hangs down along a notch opening of a rotary drum for tape winding. A hanging mechanism is provided, and the adhesive tape is wound around the bundled body by the rotation of the rotating drum in a state where the bundled body is inserted together with the hanging part of the adhesive tape into the notch portion following the notch opening of the rotating drum. in a tape winding device provided with a pressure-sensitive adhesive tape hanging mechanism times, provided above the notch opening an air spout pressing said an adhesive surface of the dripping down portion of the adhesive tape outer surface to said notch opening side by jetting air, A suction port for sucking the inner surface of the hanging portion toward the notch opening is provided below the notch opening , the air outlet is disposed obliquely downward toward the suction port, and the suction port is Toward air outlet Characterized in that it is disposed obliquely upward Te.

  With the above configuration, the air blown from the air outlet pushes the hanging part of the adhesive tape against the notch opening side of the rotating drum, so that the hanging part swells due to wind or movement of the tape winding device. This prevents the adhesive surface of the hanging part from inadvertently adhering to other parts. Since the hanging part is pressed by the jet air, the hanging part is not separated from the notch opening side of the rotating drum even if the hanging part is tilted. By temporarily fixing the adhesive tape with the blown air, it is possible to use not only a hard adhesive tape but also an adhesive tape with high flexibility and extensibility. With the hanging part pressed by the blown air, the binding object such as an electric wire is inserted into the notch opening (notch part) of the rotating drum together with the hanging part, and the rotating drum rotates to adhere the adhesive tape to the binding object. Is wound.

  With the above configuration, the hanging part of the adhesive tape is sucked to the suction port together with the air sucked from the suction port, and is held on the notch opening side of the rotary drum, so that it sags due to wind, movement of the tape winding device, etc. It is possible to prevent the lowered portion from rolling up and prevent the adhesive surface of the suspended portion from being inadvertently attached to other parts. Since the hanging part is adsorbed by the suction port, even if the hanging part is tilted, the hanging part does not leave the notch opening side of the rotating drum. By temporarily fixing the adhesive tape by suction, it is possible to use not only a hard adhesive tape but also an adhesive tape with high flexibility and extensibility. With the hanging part adsorbed to the suction port, the binding object such as an electric wire is inserted into the notch opening (notch part) of the rotating drum together with the hanging part, and the adhesive tape is attached to the binding object by the rotation of the rotating drum. Is wound.

  With the configuration described above, the air blown from the air jet outlet pushes the hanging portion of the adhesive tape toward the notch opening side of the rotating drum, that is, the suction port side, and the suction port surely sucks and adsorbs the hanging portion. The ejection of air may be for promoting adsorption. It is preferable that the air ejection direction is a direction toward the suction port. Thereby, the drooping of the hanging part due to wind or movement of the tape winding device is prevented, and the adhesive surface of the hanging part is prevented from inadvertently adhering to other parts. Since the hanging part is adsorbed to at least the suction port, even if the hanging part is tilted, the hanging part does not leave the notch opening side of the rotating drum. By temporarily fixing the adhesive tape with the blown air and suction action, it is possible to use not only a hard adhesive tape but also an adhesive tape with high flexibility and extensibility. With the hanging part at least attracted to the suction port, the object to be bound such as an electric wire is inserted into the notch opening (notch part) of the rotating drum together with the hanging part, and adheres to the object to be bound by the rotation of the rotating drum. The tape is wound.

With the above structure, from dripping down portion of the pressure-sensitive adhesive tape is extended beautiful is temporarily fixed by jetting air or suction state, the outer peripheral surface of reliably inserted while the bundles into the notch portion of the rotary drum together with the bundling body Adhering cleanly and reliably.

According to the first aspect of the present invention, the adhesive tape is reliably sucked by the synergistic effect of the air ejection and suction, or by the air ejection, and the drooping of the hanging portion of the adhesive tape is surely prevented. Therefore, inadvertent adhesion of the hanging part to other parts, folding adhesion of the hanging part itself, etc. are prevented, and the adhesive tape is removed without releasing the time and effort required for inadvertent release of the hanging part. Thus, the time and effort of disposing of the tape and the waste of the adhesive tape are eliminated, and the tape winding operation by the rotating drum is smoothly and reliably performed. In addition, even if the hanging part of the adhesive tape is tilted, the tape does not move away from the notch opening side of the rotating drum, so the tape winding device is tilted according to the direction of the bound object such as the wire or the posture of the operator. Winding can be performed, and tape winding workability is improved. Moreover, since various things, such as a softness | flexibility and a high extensibility, can be used as an adhesive tape, the versatility of a tape winding apparatus increases according to the kind etc. of a to-be-bound body.

In addition, when the hanging part of the adhesive tape is neatly stretched by blown air or suction, it is securely inserted into the notch of the rotating drum together with the bundled body, so that the outer peripheral surface of the bundled body is clean and reliable. The quality (commercial value) of the tape-wrapped electric wire after winding is increased.

  1A and 1B show an embodiment of an adhesive tape hanging mechanism and a tape winding device including the same according to the present invention, and FIG. 2 shows an adhesive tape hanging mechanism and a tape winding method using the same. Each embodiment is shown.

  As shown in FIGS. 1A and 1B, the tape winding device 1 includes an adhesive tape hanging mechanism 8, a rotating drum 6, and a tape cutting mechanism 21 on the front side of the case 2, and a tape feeding mechanism on the rear side of the case 2. 5, and a drive unit 4 for operating the rotary drum 6, the tape cutting mechanism 21, and the tape feeding mechanism 5 in the middle part of the case 2.

  As shown in FIG. 2, the adhesive tape drooping mechanism 8 includes an air ejection nozzle 25 disposed at the upper front end of the case 2 and a suction hole 26 disposed at the lower front end of the case 2. Yes.

  The front end portion of the case 2 is configured by forming a tapered wire guide portion 34 at the center in the height direction of the left and right vertical side walls 33, and the air ejection nozzle 25 is inclined obliquely rearward and downward between the upper side walls 33. The nozzle 25 is arranged behind the one side wall 33 as an air supply pipe 35, and the air supply pipe 35 is a compressor (not shown) separate from the tape winding device 1 via a hose (not shown). Or connected to factory air piping.

  The tapered wire guide portion 34 continues to the horizontal cutout portion 36 of the side walls 33, and the cutout portion 36 communicates with the cutout portion 8 of the rotating drum 6 slightly rearward. The air ejection port 25 a at the tip of the air ejection nozzle 25 faces the opening lower end side of the notch portion 36.

  A block portion 37 is disposed between the lower side walls 33, the front end surface 37a of the block portion 37 is formed vertically, and is located on the same plane as the opening 36a of the notch portion, and the rear end surface of the block portion 37 is The inclined surface 37b is in close proximity to the outer peripheral surface of the rotary drum 6.

  A suction hole 26 is provided obliquely downward in the block portion 37, a suction port 26 a of the suction hole 26 is opened on the front end surface 37 a of the block portion 37, and the suction hole 26 is separated from the tape winding device 1 via a rear pipe 38. It is connected to a vacuum suction machine (not shown) of the body. Since the suction hole 26 is formed obliquely, the suction port 26 a is defined to be larger than the cross-sectional area of the suction hole 26.

  Two suction ports 26 a are preferably provided in the width direction of the pressure-sensitive adhesive tape 17 in order to cope with a positional shift in the width direction of the pressure-sensitive adhesive tape 17. A lower suction hole 26 extends in the protruding direction of the upper air ejection nozzle 25. That is, the inclination angle of the air ejection nozzle 25 and the inclination angle of the suction hole 26 are close to each other.

  The adhesive tape 17 has a pair of guide rollers 41 that are close to the lower side of the curved surface 40a from the horizontal surface of the guide plate 40 on the upper side of the case and the curved surface 40a on the front end side of the guide plate 40 with the adhesive surface facing outward. After that, it is hung vertically in the vicinity of the front of the opening (notch opening) 8 a of the notch 8 of the rotating drum 6. Air (jet air) 42 is ejected from the upper air ejection nozzle 25 toward the hanging portion 17a of the adhesive tape 17, and at the same time, the air 43 in the lower suction hole 26 is vacuum-sucked as shown by an arrow, 42, the lower portion 17 a ′ of the hanging portion 17 a of the adhesive tape 17 is pressed against the vertical front end surface 37 a of the block portion 37, and the lower portion 17 a ′ of the hanging portion 17 a is blocked by the suction of the air 43. 37 is held in close contact with the front end surface 37a.

  As a result, not only a hard adhesive tape but also a flexible adhesive tape, a highly extensible adhesive tape, a thin adhesive tape, or other adhesive tapes 17 having different properties and materials may be used due to wind or movement of the tape winding device 1. Even if the tape winding device 1 is inclined in the lateral (width) direction or the front end of the device is inclined downward, the adhesive tape 17 is prevented. Since the hanging part 17a does not move away from the block part 37, the tape can be wound in a desired posture.

  Since the direction of the air ejection nozzle 25 and the direction of the suction hole 26 are substantially the same, the air 42 ejected from the air ejection nozzle 25 is blown through the hanging portion 17a of the adhesive tape 17 through the notch of the rotary drum 6. While pressing against the opening 8a side (the front end surface 37a of the block portion 37 in this example), the air 42 is smoothly sucked through the suction hole 26, and the pressing (adhering) action of the hanging portion 17a is performed efficiently and reliably.

The cutting band 7 is shown by slightly changing the shape of the tip as compared with that of FIG.

  In FIG. 3, the cutting band is retracted, the notch 8 of the rotary drum 6 is positioned horizontally, and the opening 8a of the notch 8 is positioned on the front side. The adhesive tape 17 hangs down along the front end surface of the lower block portion 37 between the leading end side of the cutting band 7 and the guide roller 41, and in this state, the hang-up portion 17a is vacuum-sucked by the suction hole 26. The lower end portion of the is sucked by the suction port 26a as shown by an arrow. The upper air ejection nozzle 25 is not activated.

  As shown in FIG. 4, the bundled electric wires 33 that are not yet bound with tape or the like are inserted into the notch 8 of the rotary drum 6 together with the hanging portion 17 a of the adhesive tape 17 by the operator's manual work. The adhesive surface is lightly bonded to the outer peripheral surface of the electric wire 33. The lower end portion of the hanging part 17a is drawn into the notch 8 while being in close contact with the suction port 26a, and is separated from the suction port 26a. At this time, the air suction operation of the suction hole 26 is preferably stopped by, for example, an electric wire sensor (not shown) in the notch 8. The electric wire 33 is held by an outer chuck (not shown).

  When the electric wire 33 in the notch 8 is detected by, for example, an electric wire sensor (not shown) in FIG. 4, the adhesive tape 17 is fed out from the tape reel 16 (FIG. 1) as shown in FIG. As shown by the arrow, the adhesive tape 17 is wound approximately half turn counterclockwise, and the adhesive tape 17 is primarily wound around the electric wire 33.
