溶着部を整形する装置に関する。Detailed Description of the Invention [Industrial Application Field] The present invention is used to manufacture endless ribbons such as ink ribbons used in printers, by welding both ends of a long ribbon, and then welding the remaining ends. The present invention relates to a device for shaping excised welded parts.

Various printers are used as printing devices for word processors and computers, but
Among these, wire dot printers, which print by striking a thin wire onto paper at high speed via an ink ribbon, are the mainstream.

連続的に循環して使用できるエンドレスリボンが
一般的である。 The ink ribbon used in wire dot printers is made of synthetic fiber cloth such as nylon impregnated with ink, and is generally an endless ribbon that can be used in continuous circulation without the inconvenience of replacing or rewinding. .

着後に余端を切除する方法（type Ｂ）の２方法
がある。 A widely used method for manufacturing such endless ribbons is to weld and join both ends of a long ribbon using an ultrasonic welder. This welding and joining method includes two methods: a method using fusion welding (type A) and a method in which the remaining end is cut off after welding (type B).

ので、これを特公昭55−5407号公報に記載の如く
別の超音波整形ホーンで平坦に整形してエンドレ
スリボンとする。 The method of type A is as shown in FIG. 6a and described in Japanese Patent Publication No. 54-2235, in which both ends 1a and 1b of the ribbon 1 are placed so that the same surface (side A-side A) faces each other. They are stacked in an X-shape, and the center part is pressed with an ultrasonic welding horn 3 to a pedestal 2 having an acute top, and at the same time, the remaining end 1c is welded by applying ultrasonic vibration. Next, when the ribbon is unfolded, the weld line 4 becomes protruding as shown in Fig. 6b, so it is shaped flat with another ultrasonic shaping horn as described in Japanese Patent Publication No. 55-5407. Make it an endless ribbon.
他方、type Ｂの方法は、第７図ａに図示する

してエンドレスリボンとする。 On the other hand, in the method of type B, as shown in FIG.
The central part is welded to a pedestal 2 having a smooth top with a width of about 0.5 mm by applying ultrasonic vibration while pressing it with an ultrasonic welding horn 3. Next, the remaining end 1c is cut off from near the weld line 4, and the weld line 4 formed as shown in FIG. 7b is shaped into an endless ribbon in the same manner as described above.
いずれの方法においても、エンドレスリボンに
仕上げるための整形は別の装置で行なわねばなら

ｂの溶着線の断面形状からも判るように、引張力
がtype Ｂでは剪断力になるのに対してtype Ａで
は剥離力となるためと考えられる。 In either method, shaping to finish the endless ribbon must be done using a separate device, and in the type A method, the resulting endless ribbon has a tensile strength that is only about half that of type B. However, the strength was not satisfactory. The reason for this low strength is that the tensile force becomes a shearing force in type B, but becomes a peeling force in type A, as can be seen from the cross-sectional shape of the weld line in Figures 6b and 7b. Conceivable.
しかし、type Ｂの方法は強度的に優れている

強度が低下したり、余端１ｃを切除した後の平滑
性が整形によつても得にくい等の欠点があつた。 However, although the type B method is superior in terms of strength, it has not been used much because it is extremely difficult and inefficient to cut off the remaining end 1c after welding. Furthermore, in the type B method, as shown in Fig. 5, the smooth top of the ribbon 1 with a width of about 0.5 mm of the welding line is placed on either the pedestal 2 or the ultrasonic welding horn 3 (in Fig. 5, the pedestal 2) and the other (5th
In the figure, the ultrasonic welding horn 3) has a wide top, so the ribbon on the side pushed by the thin top becomes extremely thin on both sides of the weld line 4, and the weld line at the end 1b, which should become an endless ribbon. There were disadvantages such as the strength at 4 was reduced and it was difficult to obtain smoothness after cutting off the remaining end 1c even by shaping.

In view of the above-mentioned conventional circumstances, the present invention makes it possible to weld both ends of the ribbon and shape the ribbon after cutting off the remaining ends in accordance with the type B method, which has excellent strength, and to improve the strength at the welded portion. Another object of the present invention is to provide a ribbon welding and shaping device that can produce endless ribbons with excellent smoothness.

面１２で遮断される。 When welding is completed and the ultrasonic welding horn 3 rises to its original position, the clamp device 5 automatically starts moving along the guide rail 8, and the ribbon 1 moves from one end of the guide plate 9 to the other end. . When the ribbon 1 reaches the guide groove 13, the weld line 4 of the ribbon 1 enters the guide groove 13, and as shown in FIG.
0 moves further while touching the ribbon 1, and when the ribbon 1 approaches the laser head 15, the laser oscillator is activated. A laser beam (arrow) is irradiated from a laser head 15a provided above one guide plate 9a onto the protruding slope 12 of the portion of the other guide plate 9b having the guide groove 13. Conversely, the laser beam from the lower laser head 15b is directed to the inclined surface 12 of the guide plate 9a.
is irradiated. As a result, the remaining end 1c of the ribbon 1 is accurately cut at the thinned portions on both sides of the weld line 4 that are accurately positioned by the guide groove 13, and the remaining end 1c
The laser beam that has cut the point c is blocked by the inclined surface 12 of the guide plate 9.

The welding line 4 is shaped by the ultrasonic welding horn 3. At this time, the pedestal 2 is moved by the drive device so that it comes into contact with the ultrasonic welding horn 3 over a width wider than the width of the weld line 4, as shown in FIG.
Therefore, the remaining portion after cutting off the extra end 1c is melted and pressed flat against the ribbon 1 to be shaped.

According to the present invention, it is possible to weld both ends of the ribbon using the method of type B, which has excellent strength, and to shape the remaining ends after cutting them off, using a pair of ultrasonic welding horn and a pedestal. Endless ribbons with excellent strength and smoothness can be manufactured. Moreover, the ultrasonic welding horn and the pedestal have opposing surfaces with a width larger than the width of the ribbon weld line, and during welding, these are moved in the width direction of the weld line, so only the remaining ends are thin on both sides of the weld line. As a result, the ribbon portion maintains approximately the original thickness of the ribbon, and an endless ribbon with excellent smoothness and strength at the weld line portion is obtained.
