A mouth-shaped handle 16 is attached to the mounting surface 15, and an opening 17 is provided below the handle 16 to extend from side to side. This opening 17 is a space through which a first guide band 11, a second guide band 12, and the tape 2, which will be described later, pass. A part of the opening 17 is opened and closed by a mounting plate 18 that moves back and forth in a direction perpendicular to the opening 17. The placement plate 18 and the placement surface 15 are flush with each other.

FIG. 2 is a sectional view taken along a plane passing through the center line of the opening 17 and the center line of the handle 16. As shown in this figure, the inner surface 2oa of the handle 16, the rear edge of the opening 17, 17a and the inner surface 20b of the machine base 14 are flush with each other. As shown in FIG. 2, a first guide rail 9 and a second guide rail 10, which are curved into a predetermined shape, are attached to the rear inner surface 20 formed by these.

On the other hand, the other inner surface 21a of the handle 16, the front edge 17b of the opening 17, and the other inner surface 2 of the machine base 14 shown in FIG.
1b are flush with each other, and the same guide rail 9 as the first guide rail 9 is attached to the front inner surface 21 formed by these in a symmetrical position, and the second guide rail 9 is attached to the front inner surface 21 formed by these.
A guide rail 10 identical to the guide rail 10 is attached at a symmetrical position.

The rear inner surface 20 and the front inner surface 2 facing each other

The first guide rail (refers to both the ones attached to the rear inner surface 20 and the front inner surface 21, respectively) 9
and the second guide rail (attached to the rear inner surface 20 and the front inner surface 21, respectively).

) 10 are both formed by bending a band-shaped fluororesin plastic plate provided with a guide groove 25 as shown in the figure, and the guide groove 25 allows the former 9 to
Guide the guide band 11 by supporting its both side edges in a loosely fitted state,
The latter 10 supports and guides the second guide band 12 with its both side edges loosely fitted.

The first guide rail 9 and the second guide rail 10 are arranged so that their starting ends 9a and 10a overlap at a position close to and above the bulge of the winding device 13, which will be described later. The first guide rail 9 extends diagonally upward and to the right, then bends horizontally to the left at a position substantially below the central shaft of the opening 17, and terminates near the upper end of the left side frame portion 19a of the handle 16. 9b. On the other hand, the second guide rail 10 extends diagonally upward to the right with a gentle slope, then changes direction at the lower end of the right frame portion 19b of the handle 16, rises vertically along the right frame portion 19b, and rises vertically along the right frame portion 19b. The portion 19b has a terminal end 10b near the upper end.

A winding device 13 located within the tape running space is arranged at the lower left portion of the machine stand 14 so as to be rotatable in forward and reverse directions. This lI
! The rotating device 13 is composed of a drum 22 that is driven to rotate forward and backward by a motor (not shown)', and a cylindrical fixed case 23 that surrounds this drum 22.
A slit 24 is formed in which the first guide band 11 and the second guide band 12 are inserted.

The 1' ram 22 has a first induction band 11 made of stainless steel plate.
The proximal end portion of the second guide band 12 is wound in an overlapping state. The rear ends of these guide bands 11 and 12 are fixed to the drum 22, respectively.

On the other hand, the distal end portions of the first guide band 11 and the second guide band 12 are connected to the first guide rail 9 and the second guide rail 1, respectively.
0, and the forward and reverse rotations P, P' of the drum 22
Accordingly, it moves forward or backward on the respective guide rails 9 and 10. These guide bands 11 and 12 are arranged so that they can move smoothly forward and backward on the guide rails 9 and 10;
It is flexible and has the appropriate strength necessary to guide the tape 2 in the traveling direction as described below.

It is preferable that the rotation of the drum 22 in the reverse direction P' be faster than the rotation in the forward direction P so that both the guide bands 11 and 12 can be wound back at high speed. Furthermore, as a high-speed unwinding means, a spring that stores energy when the drum 22 rotates normally is used, and the restoring force of this spring causes the drum 2 to
2 may be reversed at high speed.

On the right side of the machine stand 14, a reel 1 located within the tape running space is arranged so as to be rotatable in forward and reverse directions. This reel 1 is wound with a flexible tape 2 coated with a heat-sensitive adhesive. The reel 1 is driven by a motor (not shown) only when rotating in the direction Q for rewinding the tape 2;
The tape 2 rotates freely in the direction Q' in which the tape 2 is fed out (preferably, an appropriate braking force is applied).

A fastener 4 that removably holds the tip #3 of the tape 2 is disposed at a position directly below the opening 17 on the upper left side of the machine stand 14. This fastener 4 includes a fixed member 26 and a movable member 27.
, consisting of both tape pressers 34 and a tape end push-up plate 35, the tape tip 3 is attached and detached by the opening/closing movement of the movable member 27, and the tape tip 3 is moved to and from the mounting plate 18 by the upward rotation of the tape presser 34. It can also be temporarily fixed in between.

A cutter 30 for cutting the tape 2 is disposed near the fastener 4.

An inverted swinging arm 28 located within the tape running space is disposed between the reel 1 and the fastener 4. This swing arm 28 is attached with a presser 29 that moves relative to it, and this presser 29 is provided with a heater function. Further, the swinging arm 28 is normally disposed at the position shown in FIG. 2, and is pivoted in the upright direction in order to adhere the cut ends of the tape 2, as will be described later. The base end 31 of the swing arm 28 serves as a guide for the tape 2.

In FIGS. 1 and 2, a lid 133 32 detects the tension of the tape 2 and turns on when the tension exceeds a predetermined value.
The tension detection switch 37 for stopping the rotation of the reel 1 in the Q direction is four temporary fasteners that temporarily maintain the shape of the tape ring R, and are formed of brushes or the like.

The reel l, the fastener 4, the winding device 13, the mounting plate 18,
The swing arm 28, the presser 29, the cutter 30, etc. operate at predetermined timings, and these operations will be described later. Further, the mechanism for operating each component at a predetermined timing is constituted by a cam mechanism, an electronic control circuit, a link mechanism, etc. built into the machine base 14, but these are conventional methods disclosed in the prior art mentioned above. , so the explanation will be omitted.

Next, a method of forming a tape winding ring using the apparatus having the above configuration will be explained.

FIG. 3 shows the initial setting position of the device, in which the leading end 3 of the tape 2 is fastened to a fastener 4.

In addition, in the unwinding position of the first guide band 11 and the second guide band 12, these tips 5.6 are connected to the starting ends 9a, 10a of the first guide rail 9 and the second guide rail 1o, respectively.
Located nearby.

The first guide rail 9 and the second guide rail 10 are
As shown in FIG. 3, a first ring forming path A intersects with a portion of the tape 2 stretched between the reel 1 and the fastener 4.
and along the second ring forming path B.

When the tape tightening ring forming operation is started, the winding device 13 rotates in the direction P, and thereby the drum 22
The first guide band 11 and the second guide band 12 let out from the guide band advance on the first ring forming path A and the first ring forming path B, respectively.

These tips 5, 6 come into contact with the tape 2 and guide the tape 2 in the respective traveling directions as shown in FIG. At this time, since the reel 1 is in a state of free rotation (rotation in the Q' direction), the tape 2 is fed out from the reel 1.

As the first guide band 11 and the second guide band 12 move forward, a tape ring R is formed on the tape 2 as shown in FIGS. 5 and 6. As shown in FIG.
．． When reaching 8, the 10 times device 13 stops.

Next, the winding device 13 reversely rotates in the P' direction and winds the first guide band 11 and the second guide band 12 back to their original positions at high speed, resulting in the state shown in FIG. 7. Incidentally, if the winding device 13 incorporates the above-mentioned mainspring, the winding operation can be instantaneously performed. On the other hand, the tape loop R is not deformed due to the pulling back of the first guide band 11 and the second guide band 12, but the four corner parts are supported from the inside by four sets of temporary fasteners 37. Therefore, after being slightly deformed in the direction of diameter reduction, the shape shown in FIG. 7 is maintained.

Next, the mounting plate 18 moves forward to partially close the opening 17. Following this, as shown in Figure 8,
The tape presser 34 rotates in the S direction, and a point near the tip 3 of the tape 2 is sandwiched between its tip and the mounting plate 18.
The tape 2 is fixed between the core and the mounting plate 18. The movable member 27 of the fastener 4 continues to move in the opening direction, and the fastener 4
Leave it open. When the fastener 4 opens, the leading end of the tape 2 hangs down, but as the tape end push-up plate 35 moves forward, it is pushed up to a position along the lower surface of the mounting plate 18. During this time, the swing arm 28 rotates in the upright direction, bringing the tape 2 closer to the lower surface of the mounting plate 18 at the portion that contacts the tip.

When the swinging arm 28 reaches the position shown in FIGS. 9 and 10, the tape end push-up plate 35 moves back, and the tape end and the portion of the tape 2 located above the swinging arm 28 are brought into contact with each other. They will face each other in close proximity.

Next, the object to be bound a is inserted into the ring R of the tape and placed on the mounting surface 15 and the mounting plate 18, and this state is detected (preferably, a phototube switch is used).
, the reel 1 rotates in the Q direction to rewind the tape 2. Due to the unwinding force at this time, the ring R of the tape comes off from the four sets of temporary fasteners 37 and deforms in the direction of diameter reduction (\l1
lfl).

As shown in FIG. 12, when the tape 2 is wound around the object a to be bound, the tension detection switch 33 is actuated to stop the reel 1. Subsequently, the movable member 27 of the fastener 4 moves in the closing direction to clamp the newly fastened portion of the tape 2 between the fastener 4.

Next, as shown in FIG. 13, the presser 29 is moved upward by the lifter 32, and the tape 2
The portion C that overlaps this is bonded by applying pressure and heat.

Thereafter, as shown in FIG. 14, the cuckoo 30 is operated to cut the tape 2 along the upper surface of the fastener 4. At this time, as shown in FIG. 14, the cut end d of the tape 2 hangs down. After the adhesion, the tape presser 34 rotates in the reverse S direction, moves away from the lower surface of the tip of the tape 2, reaches a substantially horizontal position, and stops, while the presser 29 continues to move downward. Then, as shown in FIG. 15, the swinging arm 28 rotates forward to slightly change the angle, and the presser 29 moves upward again, so that the hanging portion (cant portion) d
is glued to the tape tip above it.

As described above, both ends of the part of the tape 2 wound around the object a are overlapped and bonded together, but then, as shown in FIG. 16, the mounting plate 18 is moved back and the tape 2 is It is in a state where it is directly bound to the object to be bound a. The swing arm 28 returns to its original position as shown in FIG. 3, and the entire operation is completed.

The present invention can be configured in various ways other than those shown in the above embodiments. For example, in the device invention, the aspects of the fastener 4 and the swinging arm 28 are not limited to those shown in the above embodiments, and the swinging arm 28 is not an essential component. Alternatively, it is also possible to configure the device invention so that the four sets of temporary fasteners 37 are omitted.

Even in the method invention, it is possible to configure the invention in a manner other than the above-mentioned embodiments. In the above embodiment, the tip of the first guide band 11 that moves along the first guide rail 9 is the first inductor 5, and the second guide band 1 that moves along the second guide rail 10 is used as the first inductor 5.
2 is a second inductor 6, and these inductors 5.6 are configured to form a ring R of the tape by traveling along the first ring forming path A and the first ring forming path B, respectively. However, the first guide band 11 and the second guide band 12 can be replaced with other embodiments. For example, using a prior art chain drive system, a drive pin is attached to each of the chains running along the first and first wheel forming paths A and B, and these drive pins are connected to the first and second inductor 5. It may be set to .6. Alternatively, the first guide band 11 and the second guide band 12 may be wound on separate winding devices 13.

(Effects of the Invention) Since the present invention has the above configuration, the following effects can be achieved.

First, in the method invention, since a tape ring can be formed by running two inductors, the time required to wind up the tape and form a ring is shortened compared to the prior art, thereby increasing work efficiency. It has the effect of being able to

On the other hand, the device invention not only has the effect of providing a device that improves work efficiency, but also has a configuration in which a tape ring is formed using a pair of guide bands, so that the structure is improved. It is possible to simplify and reduce costs,
Furthermore, it has the effect of solving the noise problem.
