Incidentally, the rotation of the drum 22 in the reverse direction P' is configured to be faster than the rotation in the forward direction P, so that both the guide bands 11, 12
It is preferable to be able to unwind the paper at high speed. Furthermore, as a high-speed unwinding means, the drum 2
The drum 22 may be reversely rotated at high speed by using a spring that stores energy during normal rotation of the drum 22 by the restoring force of the spring.

The reel 1 located in the tape running space D is arranged on the right side of the machine base 14 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, and it rotates freely (appropriate braking force must be applied) in the direction Q' for rewinding the tape 2. ).

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 consists of a fixed member 26, a movable member 27, a tape presser 34, and a tape end push-up plate 35. The tape end 3 is attached and detached by the opening and closing movement of the movable member 27, and the upper part of the tape presser 34 is The tape tip 3 can also be temporarily fixed between the mounting plate 18 and the mounting plate 18 by rotating the tape.

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

An inverted L-shaped swinging arm 28 located within the tape running space D 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.

1 and 2, 32 is a lifter for moving the presser 29 upward; 33 detects the tension of the tape 2; when the tension exceeds a predetermined value, the switch is turned on to rotate the reel 1 in the Q direction; Tension detection switches 37 for stopping the tape ring R are four temporary fixing devices that temporarily maintain the shape of the tape ring R, and are formed of brushes or the like.

The reel 1, fastener 4, winding device 13, mounting plate 18, swing arm 28, presser 29, cutter 30, etc. operate at predetermined timing.
These operations will be described later. Furthermore, the mechanism for operating each component at a predetermined timing is comprised of a cam mechanism, an electronic control circuit, a link mechanism, etc. built into the machine base 14, but these are also disclosed in the prior art. Since this is a well-known method, its 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. Further, in the unwinding position of the first guide band 11 and the second guide band 12, the tips 5 and 6 thereof are located near the starting ends 9a and 10a of the first guide rail 9 and the second guide rail 10, respectively. There is.

The first guide rail 9 and the second guide rail 10, as shown in FIG. A and the second ring forming path B.

When the tape winding process begins,
The winding device 13 rotates in the P direction, whereby the first guide band 11 and the second guide band 12 unwound from the drum 22 are moved to the first ring forming path A and the second guide band 12, respectively.
Move forward on ring formation road B. Then, these tips 5 and 6 come into contact with the tape 2, as shown in FIG.
The tape 2 is guided in each traveling direction. At this time, the reel 1 is in a state of free rotation (rotation in the Q' direction), so 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. When these tips 5 and 6 reach the terminal positions 7 and 8 of the first ring forming path A and the second ring forming path B as shown in FIG. 6, the winding 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. still,
If the winding device 13 incorporates the above-mentioned mainspring, the winding operation can be instantaneously performed. On the other hand, the tape ring R is formed by unwinding the first guide band 11 and the second guide band 12.
Although it is not deformed, four sets of temporary fasteners 37 are used to prevent it from deforming.
Since the four corner portions are supported from the inside, the shape is maintained as shown in FIG. 7 after being slightly deformed in the direction of diameter reduction.

Next, the mounting plate 18 moves forward and the opening 17
Close part of the lid. And following this, the 8th
As shown in the figure, the tape presser 34 rotates in the S direction, pinches a point near the tip 3 of the tape 2 between its tip and the mounting plate 18, and places the tape 2 at this point. It is fixed between the plate 18 and the plate 18. The movable member 27 of the fastener 4 continues to move in the opening direction, bringing the fastener 4 into an open state. When the fastener 4 opens, the tip end b 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 retreats, and the swinging arm 28 of the tape tip b and the tape 2
The portion located above is located close to and facing each other.

Next, when 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, this state is detected (it is preferable to use a phototube switch). The reel 1 rotates in the Q direction to rewind the tape 2. Due to the unwinding force at this time, the loop R of the tape is turned into four sets of temporary fasteners 37.
It comes off and deforms in the direction of diameter reduction (Fig. 11).

As shown in FIG. 12, when the tape 2 is wound tightly around the object a to be bound, the tension detection switch 33 is activated and the reel 1
to stop. Next, the movable member 27 of the fastener 4
moves in the closing direction and clamps the new fastening portion of the tape 2 between the fasteners 4.

Next, as shown in FIG. 13, the presser 29 is moved upward by the lifter 32, and the tape tip b and the overlapping portion c of the tape 2 are bonded together by applying pressure and heat.

Thereafter, as shown in FIG. 14, the cutter 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 b of the tape 2, and then reaches a substantially horizontal position and stops, while the presser 29 moves downward. do.

Next, as shown in FIG. 15, the swinging arm 28 is further rotated forward by a slight angle, and the presser 29 is moved upward again, so that the hanging portion (cut portion) d is moved to the upper end of the tape. Part b
is glued to.

As described above, both ends of the tape 2 wrapped around the object a are overlapped and bonded together, and then, as shown in FIG. 16, the mounting plate 1
8 moves back, and the tape 2 becomes directly tied to the object 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 a device invention,
The aspects of the fastener 4 and the swing arm 28 are not limited to those shown in the above embodiments, and the swing 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 used as the first inductor 5, and the tip of the second guide band 12 that moves along the second guide rail 10 is used as the second guide. The ring R of the tape is formed by running the guide elements 5 and 6 along the first ring forming path A and the second ring forming path B, respectively. The first induction zone 11 and the second induction zone 1
2 can be replaced with other embodiments. For example, using the prior art chain drive system,
A drive pin may be attached to each of the chains running along the first and second wheel forming paths A and B, and these drive pins may be used as the first and second inductors 5 and 6. Alternatively, the 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,
Compared to the prior art, this method has the effect of reducing the time required to wind up the tape and forming a ring, thereby increasing work efficiency.

On the other hand, the device invention has the effect of being able to provide a device that improves work efficiency, and also has a structure 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, and also has the effect of solving the noise problem.
