加工機械に関するものである。Detailed Description of the Invention [Technical Field] The present invention is directed to processing sheets of a plurality of layers of processed materials made of thermoplastic resin by applying heat to the processed materials and pressing and sandwiching the processed materials together. Regarding a welding machine that welds each other, in particular, it is equipped with a transfer device such as a roller to transport the welded sheet-like processed materials in one direction, and the welding machine continuously welds the sheet-like processed materials. The present invention relates to a welding processing machine capable of performing the welding process.

のが既に提供されている。Prior Art Conventionally, this type of welding processing machine uses a heat source such as a heater placed in advance along the supply route from the supply source of the sheet-shaped processing material to the processing position.
After applying heat to the sheet-shaped processing material passing near the heater, the sheet-shaped processing material is pressed and held between a pair of opposing rollers, and the rollers are driven to rotate in one direction. There have already been provided devices in which the processed material is subjected to continuous welding processing.

近傍で溶融されてしまつたりすることもあつた。 However, in the conventional apparatus described above, radiant heat is indirectly applied to the sheet-shaped processed material that is passed close to a heat source such as a heater, so not only is the thermal efficiency poor, but the processed material that is passed through the If the supply rate is constant, the optimum heat can be applied almost uniformly to the sheet-shaped processing material, but if the supply rate is changed or stopped midway through, even if the set temperature of the heater etc. Even if the heater temperature is changed, the heater temperature is not changed quickly, so it is not possible to apply optimal and uniform heat to the processed material, and when the feed rate is extremely reduced, the processed material may be melted near the heater. It was hot too.

溶着機が提供されている。 In addition, this type of welding machine uses ultrasonic vibrations from a processing horn that vibrates ultrasonic waves to heat the processing material, instead of heating the sheet-like processing material using radiant heat from a heat source such as a heater as described above. There has been provided an ultrasonic welding machine that welds sheet-like workpieces by pressing the workpieces heated by a heating method using frictional heat generated therein into pressure contact with each other.

た。 However, in the above ultrasonic welding machine,
Ultrasonic vibrations were applied to the polymerized surfaces of the polymerized materials by the processing surface of the processing horn subjected to ultrasonic vibrations, and the polymerized surfaces were caused to generate ultrasonic heat and welded to each other. If the processed material located on the processed surface side of the horn is thick or made of a relatively soft material, sufficient ultrasonic vibration cannot be applied to the overlapping surface. The polymerization surface did not generate sufficient heat and could not be welded. In addition, the vibration element for applying ultrasonic vibration to the machining horn is not only expensive, but also requires a lot of time to design the machining horn.

は明白である。 In the above embodiment, the processing horn 4 including the processing surface 5 as a support member for supporting the material to be processed is subjected to ultrasonic vibration, and the processing surface 5 and the presser roller 6 are vibrated ultrasonically.
Due to the synergistic effect of heat generation due to ultrasonic heat generation and heat generation due to eddy current loss of the annular body 6b of the presser roller 6 on the overlapping surface of the processed material W and the sewing tape 19 held between them. Thus, an example has been shown in which a good welding process is performed on the processed material W and the sewing tape 19, but the support member does not necessarily have to be a support surface that supports the processed material 4 even if it is not subjected to ultrasonic vibration. It is obvious that any member having the above can be substituted.

It goes without saying that the supporting member facing the roller 6 may be made of, for example, a plate-shaped heat-resistant glass, and may be positioned on the opposite side of the plate glass from the pressing roller 6.
