Abstract

PURPOSE:To obtain the titled machine capable of accelerating working speed and performing stable welding without increasing ultrasonic oscillation output by heating a push roller and giving auxiliary heat to work material. CONSTITUTION:A push roller 16 is heated, work material is put by the spring force of a compression spring 27 between the push roller 16 and a working surface 14, a working hone 13 is placed under ultrasonic oscillation and an oscillator assembly 7 and the push roller 16 are rotated. The working material is welded not only by heating due to ultrasonic oscillation given from the working surface 14 but secondarily by the heat from the push roller 16.

First, the power switch 41 is turned on to heat the presser roller 16 in advance, and the presser foot lifting lever 26 is operated to hold the presser roller 16 in the upper position. Materials to be processed (not shown) are overlapped to form a machining surface 14 of a machining horn 13 and a presser roller 16.
Then, by lowering the presser foot lifting lever 26, the presser foot roller 16 is lowered. Then, the workpiece material is held between the processing surface 14 and the presser roller 16 by the spring force of the compression spring 27. In this state, when the processing horn 13 is ultrasonically vibrated and the motors 8 and 22 are driven to rotate the vibrator assembly 7 and the presser roller 16,
The two workpiece materials are the processing surface 14 and the presser roller 1.
Ultrasonic vibrations are applied from the machining surface 14 to the portions clamped by the rollers 6, and heat is applied from the presser roller 16, and the clamped portions are welded and sent sequentially to be heat welded together. .

し得て寿命の長期化を図り得る。 That is, the workpiece material not only generates heat due to the ultrasonic vibrations applied from the processing surface 14, but also generates heat from the presser roller 1.
6. Therefore, it is necessary to slow down the processing speed even when processing a workpiece material with a large thickness or a high heat distortion temperature. This makes it possible to increase the machining speed, such as by eliminating the In this case, since it is not necessary to increase the ultrasonic vibration output, there is no need to increase the size of the ultrasonic transducer 10 and the oscillator for driving the ultrasonic transducer 10, and there is no risk of increasing the size of the entire device. It disappears. In addition, heat is applied substantially uniformly to each part of the workpiece material from the presser roller 16, so that the welding process is stabilized. Furthermore, in this case, the temperature of the presser roller 16 is maintained by the heating means 34 at an optimum temperature depending on the material to be processed, so that the welding process can be further stabilized. In addition, heater 2
8 is supported by the roller support body 20 via a supporting member 29 having good heat insulation properties and a spacer 30 made of heat insulating material, and the presser roller 16 is supported by the rotation shaft 18 via a heat insulating member 17. 28. The heat of the presser roller 16 has an adverse effect on the bearing 2.
There is no risk of winning the first prize. Further, the heat of the heater 28 is transmitted from the heat transfer body 32 to the press roller 16 via a small gap between the heat transfer body 32 and the press roller 16, and the heater 28 is arranged in a fixed state. Therefore, a slip ring for power supply to the heater 28 can be made unnecessary, and the life of the heater 28 can be extended.
