った。(Prior technology) The rollers of the high-frequency sewing machine installed in a part of the conventional high-frequency sewing machine that joins vinyl films are linear and fixed rollers such as high-frequency heating rollers and pressure rollers. Many difficulties have arisen in welding the film. Furthermore, there is no method for preheating the welding portion of the film to be welded only during the welding operation and then feeding it into the high-frequency sewing machine.

ち、商品価値を低下さす問題がある。(Problems to be Solved by the Invention) With such a conventional high-frequency sewing machine roller, during vinyl film welding work, the pressure roller for pressing the vinyl film is pressed so that the electrode surface of the high-frequency sewing machine roller is in a straight line. Because of this, the contact surface between the pressure roller and the high-frequency roller cannot be pressurized uniformly, resulting in uneven welding degree at the welded part of the film, lowering the welding strength, and reducing the product value. There is.

熱源より間接的な伝導熱による加熱方法であってローラ
ーの加熱に時間を必要とし、冬期などには連路のできな
い問題点があった。Also, it has been known that this effect can be improved by heating the pressure roller during film welding, but this heating method uses conduction heat indirectly rather than a heat source, and it takes time to heat the roller. However, there was the problem that continuous routes were not possible during the winter season.

きない問題がある。又、その他諸問題点が多かった。In addition, when welding a film using a high-frequency sewing machine, the temperature of the film itself to be fed must be within a temperature range of 40 to 60 degrees.
Although it is necessary to always feed at a constant temperature, there is a problem that this is not possible. In addition, there were many other problems.

高周波ミシンローラーの電極を反発力のある材料をもっ
てこの外周面を外周方向に適当湾曲させ。The electrode of a high-frequency sewing machine roller is made of a material with repulsive force, and its outer peripheral surface is appropriately curved in the outer peripheral direction.

吹付することで完成される。The contact area with the pressure roller should be uniform at the middle and both outer sides, and the axis of the pressure roller should be able to move freely approximately at right angles to the direction of travel of the film to be welded, and the heating of the pressure roller should be made uniform. The method uses both conduction heat and double radiation heat from the heating element, and the preheating of the welded film is completed by blowing hot air onto the welded film in front of the welding roller only during welding operation. be done.

、局部的に圧着爪を変ることができる。(Function) By curving the electrode in the outer circumferential direction, or by curving the outer diameter of the pressure roller to an appropriate degree from the center to the outer periphery, the welded part of the film is pressed from near the center, and the welded part is pressed. There is no air layer inside, the crimp claws on the inside and outside are uniform, and the crimp claws can be changed locally.
加圧ローラーの軸をＷ４看フィルムの進行方向に対して

る。Since the axis of the pressure roller can be moved approximately perpendicularly to the traveling direction of the W4 film, the left and right pressing claws of the film welding portion can be made equal, and the pressing claws can be locally changed.
溶着直前の被溶着フィルムを一定温度に予熱することで
安定した溶着ができる。Stable welding can be achieved by preheating the film to be welded to a certain temperature just before welding.

りにくい。The electrode (9) attached to the outer periphery of the high frequency roller (1) is caused to conform to the outer periphery of the pressure roller by the contact pressure (28) of the pressure roller (2) due to the cushioning material provided inside the electrode. At this time, if the outer surface of the electrode (9) is linear and the internal cushioning material has a uniform reaction force, the pressing force of the film is actually very small, but it is weak in the center and on one side. This is a phenomenon where the parts become stronger and it is difficult to achieve uniformity.

大きな問題点がある。(Embodiment of the third invention) It is desirable that the pressure of the pressure roller (2) to the high frequency roller (1) always be suppressed parallel to the core. However, this is not possible due to various external forces and mechanical structure. Therefore, it is impossible to do so, and currently there is a major problem in that irregularities in the degree of welding occur on the sides of the roller.
これを解消するために、加圧ローラー（２）の支軸を次
の構造とした。In order to solve this problem, the support shaft of the pressure roller (2) has the following structure.
加圧ローラー（２）は軸（ｌＯ）を介して回転自在に、
この加圧ローラーを略囲む中空四角形状の口形枠（１１

）と回動自在とされている。The pressure roller (2) is rotatable via the shaft (lO),
A hollow rectangular mouth-shaped frame (11
), and this mouth-shaped frame (11) is supported on the opposite side of the shaft (1O
) and the main frame (
It is supported by bearings (32) formed in relative shapes on both sides of the shaft (14), and the arrow (16) is supported by the shaft (13).
) and is said to be rotatable.
このように加圧ローラーが軸（１３）を軸として回動で
きることは、高周波ローラー（１）の接触面に対し、加
圧ローラーの接触面が常時左右の別なく均等状態で接触
し、フィルムの溶着度を均等にするものである。なお、
加圧ローラーを軸支する軸受に上下自在のクッション材
を介することでローラー加圧の変差を緩和さすこともで
きる。The fact that the pressure roller can rotate around the shaft (13) in this way means that the contact surface of the pressure roller is always in even contact with the contact surface of the high-frequency roller (1), regardless of whether it is left or right, and the film can be This is to equalize the degree of welding. In addition,
It is also possible to alleviate variations in roller pressure by interposing a vertically movable cushion material on a bearing that pivotally supports the pressure roller.

Or drill multiple holes (3
4) The heat generated by the heating element (33) mounted inside is indirectly conducted to the pressure roller via the main frame,
The pressure roller is heated by multiple radiation heat through the communication hole (35), and by bringing the pressure roller and the heating element close together, the heating effect of the pressure roller is improved and the temperature of the roller is controlled. be able to. The hole (36) is an insertion hole for a temperature measuring element for temperature control.

風を制御することが望ましい。The film welding operation is sometimes stopped while the film to be welded is held between the high frequency roller (1) and the pressure roller. At this time, constantly blowing hot air onto the film to be welded causes the film to reach an abnormally high temperature, which impairs the welding effect. For this reason, it is desirable to control the hot air while the film is being welded.

する。In FIG. 2, heat generated from a hot air generating device having a suitable structure, such as a ventilation heating element (33), is transferred to a fan (40).
The hot air is passed through a duct (42
), during the film welding operation, air is blown to the welded portion of the film in the direction of an arrow (49), and is discharged from the outlet (51) to the unwelded portion of the film to raise the temperature of this unwelded portion. At the same time as the welding operation is stopped, the damper (44) installed in the duct (42) moves and switches to the dotted line damper (48) via an appropriate mechanism 1, for example, an electric device, and guides the hot air in the direction of the arrow (50) to the discharge duct (43). ) Discharge to a more appropriate location. At this time, it is also effective to discharge an appropriate amount of hot air to the film side to keep the unwelded film warm. When the film welding operation is started, the damper (44) returns to its original position.
