[Detailed description of the device]

[0001]

This invention relates to an ultrasonic processing machine,
In particular, the present invention relates to an ultrasonic processing machine in which a cloth-like material is cut into a predetermined shape and patterned by applying frictional heat due to ultrasonic vibration.

[0002]

2. Description of the Related Art As described in, for example, Japanese Utility Model Publication No. 3-3596, a cloth-like material, a film, a sheet or the like of chemical fibers is predetermined by utilizing frictional heat generated by ultrasonic vibration generated by an ultrasonic oscillator. It is performed by fusing or welding into a shape.

A table provided with an ultrasonic wave oscillating horn and a processing roll having a machined portion of a predetermined pattern engraved thereon are advantageously used in this fusion welding process. The frictional heat generated by the ultrasonic wave oscillating horn of the table and the processing roll are used. The material to be processed is cut or patterned into a predetermined shape by crimping with.

As described above, this ultrasonic processing is performed by the cooperation of the ultrasonic oscillating horn and the processing roll. In many cases, the size of the oscillating horn has a predetermined size in relation to the output. It is set. However, even if the width of the processing horn is increased and the ultrasonic vibration is not transmitted even if the width of the work piece is increased by ultrasonic wave processing, the fusion welding cannot be performed. If wide processing is to be performed, a device with a large oscillating horn, that is, a device with a large output must be used, which is a heavy burden in terms of equipment and economy.

[0005]

The present invention has been proposed in view of such a situation, and is mainly a novel ultra-high temperature welding process capable of performing wide fusing welding without enlarging the oscillation horn. The structure of the sonic processing machine is proposed.

The present invention also proposes a structure of an ultrasonic processing machine capable of performing the most effective ultrasonic processing by adjusting the positional relationship between the oscillation horn and the processing roll.

[0007]

[Means for Solving the Problems] That is, this invention is
In the one in which the workpiece placed on the table provided with the ultrasonic oscillating horn is fused or welded into a predetermined shape by the rotation of the processing roll provided on the machine base, The ultrasonic processing machine is characterized in that the provided table is reciprocated in a direction perpendicular to the rotation direction of the processing roll.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a schematic front view showing a part of an ultrasonic processing machine showing the embodiment of the present invention in a cutaway section, and FIG. 2 is a table. Is a top view of the main part in the retracted position, and FIG. 3 is a top view of the main part in which the table is also in the forward position.

The ultrasonic processing machine 10 shown in FIG. 1 has a table 20 equipped with an ultrasonic oscillating horn 21 and a processing roll 30 provided on a machine base 11 and is provided with a work material such as a chemical fiber. The material to be processed is cut into a predetermined shape or patterned by frictional heat generated by the ultrasonic wave oscillating horn 21 and rotary pressure bonding by the processing roll 30.

Reference numeral 22 in the figure denotes an ultrasonic oscillator (not shown) and a rotary drive motor 23 for the ultrasonic oscillator horn 21.
It is a known ultrasonic oscillation horn drive unit including the above, and is configured integrally with the table 20. Reference numeral 32 is a bearing member for the processing roll 30, 35 is a drive belt for rotating the processing roll 30, 40 is a drive motor thereof, and 45 is a gear box.

In the ultrasonic processing machine 10 of the present invention,
As shown in the figure, the table 20 provided with the ultrasonic wave oscillating horn 21 rotates in the rotating direction of the processing roll 30 (front and back directions in the figure).
It is configured to reciprocate in a direction perpendicular to (right and left direction in the figure).

That is, in this embodiment, the table 20
Is connected to the cam plate member 50 via the connecting member 55 on the side portion thereof, and is configured to reciprocate in the left-right direction in the drawing by the rotation of the cam plate member 50. The cam plate member 50 is driven by the drive motor 40 of the processing roll 30 via gear boxes 45 and 47 as shown in the figure. Reference numeral 51 is a rotation axis.

The partial top views of FIGS. 2 and 3 show the operational relationship between the cam plate member 50 and the table 20, and a connecting member 55 connected to the table 20 is provided on the rear surface side of the cam plate member 50. It shows a state in which the cam groove 52 having a predetermined shape is guided to reciprocate. Note that reference numeral 27
And 29 are rails of the table 20, 56 is a cam follower, arrow a is the rotation direction of the processing roll 30, and arrow b is the feed direction of the workpiece M.

As will be better understood from FIGS. 2 and 3, the processing roll 30 having a processing portion 31 having a predetermined shape or pattern on the circumferential surface of the processing roll 30 is wider than the ultrasonic oscillating horn 21. Complete ultrasonic processing cannot be performed with the conventional fixed structure.

Therefore, when processing the right side portion of the roll 30 as in the present invention, the table 20 having the ultrasonic oscillating horn 21 is moved to the right side (FIG. 2), and the roll 30 is also moved.
When the table 20 is moved to the left side together with the ultrasonic oscillating horn 21 when processing the left side portion (Fig. 3), even such a wide roll 30 can be completely and effectively ultrasonically processed. it can.

At this time, the table 20 is moved to the processing roll 30.
If it reciprocates at a predetermined speed in synchronization with the rotation of
Smooth movement is possible corresponding to the processing portion 31 of the processing roll 30.

Although an example using a wide roll is shown here, the ultrasonic oscillating horn 21 has a characteristic that the output is more likely to be cut off more in the peripheral portion than in the central portion, so that it is a normal size. Even in the case of the roll of the sword, it is possible to move the table for efficient processing.

[0018]

As described above, according to the present invention, even when a wide welding roll is used to perform wide fusing and welding processing on a workpiece, the oscillation horn can be efficiently and effectively used without enlarging the oscillation horn. Can be processed. In addition, even when using a normal processing roll, the most effective ultrasonic processing can be performed by adjusting the positional relationship between the oscillation horn and the processing roll, if necessary. The usefulness of the processing machine can be significantly improved.
