[0002]

2. Description of the Related Art An ultrasonic vibration type film welding apparatus is provided with an ultrasonic horn for generating ultrasonic vibration and a receiving portion using an idler roller or the like. In this configuration, the film is folded and passed through a superposed polymer film, and while the polymer film is running, ultrasonic vibration is applied to fuse the films together.

Generally, the idler roller (receiving portion) is configured to be supported by a supporting spring for applying a predetermined clamping pressure. When a film is mounted, the supporting spring is pressed and contracted to reduce the distance between the ultrasonic horn and the receiving portion. It is configured such that the polymer film is spread and passed through, and the polymer film is sandwiched between the ultrasonic horn and the receiving portion by the return elastic force of the bearing spring.

Therefore, the conventional ultrasonic vibration type film welding apparatus has a structure in which the receiving portion is supported by the support spring, so that the film can be easily mounted and the superposed film can be attached to the ultrasonic horn and the receiving portion. The film can be welded while being held by a predetermined holding pressure.

[0005] However, if the supporting spring is made strong so that sufficient ultrasonic vibration can be applied and welded even with a thin film, when a thick film is mounted, an unnecessarily strong clamping pressure works and a strong biting force is exerted. Will work.

Therefore, when a thick polymerized film is passed, or depending on the material of the film, the running of the film does not go smoothly, or the film breaks during running,
There is a possibility that the running of the film may be hindered.

Therefore, in the conventional apparatus, the setting of the spring pressure of a film having a thickness greater than a predetermined thickness or a film of a material which easily tears must be performed by exchanging each spring pressure individually, and cannot be used simply with the same spring pressure. .

The present invention finds such a problem in the conventional apparatus, solves the problem, easily adapts to the film thickness and the material of the film, can stably weld the film without hindering the film running. It is an object of the present invention to provide a revolutionary film welding device and a packaging device provided with the film welding device.

Therefore, even if the facing distance L is adjusted, the receiving portion 21 is always supported by the elastic member 22, so that the polymer film 1 passed between the ultrasonic horn 20 and the receiving portion 21 is The elastic force is always held by the return elastic force. However, for example, by expanding the facing distance L, the elastic force can be restricted.

For example, by moving the receiving portion 21 together with the elastic body 22,
By preventing the elastic clamping force from becoming unnecessarily strong even when the thick film 1 is passed, or by allowing the elastic clamping force to work only to the position of the receiving portion 21 when the film 1 does not pass through, the film 1 bites. The limit position can be regulated.

That is, a strong biting force that does not exceed the facing distance L (L ₂ ) does not occur.

Therefore, this facing distance L is set to
By adjusting and setting according to the thickness of the film and the material of the film, it is possible to regulate the film clamping pressure so that it does not exceed the biting limit force which may hinder the film running of the polymerized film 1. Even if the thickness of 1 is changed, by adjusting the facing distance L accordingly,

DESCRIPTION OF THE PREFERRED EMBODIMENTS Specific embodiments of the present invention will be described with reference to the drawings.

In the present embodiment, the idler roller 21A serving as the receiving portion 21 provided to face the ultrasonic horn 20 is provided as follows.

A plate-like mounting member 23 is provided horizontally on a mounting surface 27 at a predetermined interval so as to be horizontally rotatable about a fulcrum shaft 25, and the mounting member 23 is rotated away from the fulcrum shaft 25. A roller support shaft 21B is provided at the side end having a large moving amount.
B is provided with the idler roller 21A which can be ultrasonically welded while rotating in accordance with the feeding of the film 1 and smoothly running the film.

An upright wall 26 is provided on the side of the mounting body 23 opposite to the side where the idler roller 21A is provided, and an elastic body 22 employing a coil spring is abutted on the outside of the upright wall 26. And the mounting body 23 is elastically supported by the elastic body 22 so that the idler roller 21
A is configured to bear the oppression.

An eccentric pressing cam body 24 is provided at a position where the inside of the vertical wall 26 of the mounting body 23 is pressed, and by rotating the pressing cam body 24, the pressing cam body 24 is rotated. The mounting body 23 is pressed by the cam surface, and the mounting body 23 is pivotally moved about the fulcrum shaft 25 by a predetermined amount to move and adjust the position of the idle roller 21A with respect to the ultrasonic horn 20.
The distance L between the roller and the idler roller 21A can be adjusted and set.

Therefore, for example, when the thick polymer film 1 is passed, the facing distance L is slightly increased from L ₁ to L _{2 as} compared with the case where the thin polymer film 1 is passed.
The pressing cam body 24 is rotated by rotating and adjusting a rotating operation portion 28 such as an adjustment bolt protruding from the mounting surface 27 provided on the mounting surface 27, and the upright wall portion 26 is moved outward by the cam surface. The mounting body 23 is rotated in a direction away from the ultrasonic horn 20 against the elastic body 22 by being pressed in a direction away from the ultrasonic horn 20).

Therefore, the idler roller 21 provided on the mounting body 23
A is moved and adjusted in a direction away to the ultrasonic horn 20, opposing distance L between the ultrasonic horn 20 and the idling roller 21A is (spread to L ₂₎ is adjusted.

Conversely, when the pressing cam body 24 is rotated, for example, in the opposite direction, the elastic body 22 is reduced by the amount of the pressing force exerted by the cam surface.
The return force causes the mounting body 23 to return, and the facing distance L becomes L ₁
Can be narrowed down to

Further, in this embodiment, the elastic body 22 does not move together with the receiving portion 21 due to the rotational movement adjustment of the mounting body 23, and the elastic body 22 is pushed and contracted by the movement of the mounting body 23, so that the clamping elastic force is reduced. In the present embodiment, the clamping gap pressure is not weakened in the adjustment of the facing distance L in this embodiment as compared with the conventional example in which the spacing cannot be adjusted simply by increasing the facing distance L. A clamping force corresponding to the thickness can be given, and good ultrasonic welding can be performed. In addition, in the present embodiment, the clamping force for further narrowing the set facing distance L is prevented by the pressing cam 24 acting as a stopper.

Therefore, when the elastic film 22 is pressed and shrunk at the time of mounting, the polymer film 1 is passed between the ultrasonic horn 20 and the idler roller 21A serving as the receiving portion 21, and the transporting roller 29 is driven to carry the nipping and running. The return elastic force of the elastic body 22 acts on the polymer film 1 as before, and the polymer film 1 is ultrasonically welded while always being held at a constant holding pressure according to the thickness of the polymer film. The return elastic force does not work at all for a predetermined facing distance L or less.

That is, there is no strong biting force to reach the distance L or less.

Therefore, the facing distance L is set to
By adjusting and setting according to the thickness of the film and the material of the film, it is possible to regulate the film clamping pressure so that it does not exceed the biting limit force which may hinder the film running of the polymerized film 1. Even if the thickness of 1 is changed, by adjusting the facing distance L accordingly,
The film can be run with a predetermined clamping pressure without tearing the film during running or hindering the running of the film.
Good ultrasonic vibration welding becomes possible.
