あつた。Conventional technology Conventionally, this type of welding processing machine has a heat source such as a heater placed in advance along the supply path of the sheet-shaped processing material supplied from the supply source, and the sheet-shaped processing machine passes the sheet-shaped processing material near the heater. After applying heat to the processed material, the sheet-shaped processed material is pressed and sandwiched between a pair of opposing rollers, and the rollers are driven to rotate in one direction to perform a continuous welding process on the sheet-shaped processed material. Something like this is already available. However, in the conventional apparatus described above, indirect radiant heat is applied to the sheet-shaped processing material passing through a heat source such as a heater. The optimum heat can be applied almost uniformly to the processed material, but if the supply speed is changed or stopped midway through, the heater temperature will not change quickly even if the set temperature of the heater is changed. Therefore, optimal and uniform heat cannot be applied to the processed material, and when the feeding rate is extremely reduced, the processed material may end up being melted in the heat source such as the heater. In addition, in the conventional apparatus described above, since it takes time for the heat source such as a heater to reach a substantially constant temperature, there is a loss of time for preheating at the start of work, etc.
Moreover, since indirect radiant heat is applied over a wide area to the sheet-shaped processed material, only a small portion of the amount of heat is actually applied to the processed material, which poses the problem of extremely poor thermal efficiency. It was hot.

づれも実用性に乏しいものであつた。 In addition to the above-mentioned welding machines, this type of welding machine heats a presser roller that is arranged to press and hold the sheet-shaped material without applying heat to the sheet-shaped material in advance. Various methods have been proposed in which the sheet-shaped processing material is directly heated by a heated presser roller and the sheet-shaped processing material is welded. Not only is the mechanical structure complicated, but there are also problems with the durability of the electrical contacts that supply current to the heater, and the heater is placed close to the presser roller. In the case where the presser roller is indirectly heated by, for example, the presser roller, there are problems such as not only poor thermal efficiency but also extremely poor controllability as the surface temperature of the presser roller cannot be quickly controlled. However, all of them lacked practicality.

This is for supplying an alternating current of an ultrasonic frequency (20 KHz to 50 KHz) based on the oscillation frequency of the coil 9b (not shown) to the coil 9b. Control circuit 33
is for outputting a control signal for controlling the oscillation frequency of the oscillation circuit in the inverter 30, and includes a pyroelectric detection element (not shown) for detecting the surface temperature of the presser roller 6c. The oscillation frequency of the oscillation circuit in the inverter 30 is adjusted based on the temperature signal from the temperature detection circuit 34, and the heat generation amount of the annular body 6b is determined by the change in eddy current loss accompanying the change in the effective impedance of the annular body 6b. It is configured so that it can be adjusted. Next, the operation of this device configured as described above will be explained below.

After the presser foot lifting lever 12 is operated, the electromagnetic induction device 9 and the roller support 8 including the presser roller 6 are lifted so that the outer peripheral surface of the presser roller 6 is separated from the processing surface 5d as shown in FIG. raise into position. Next, the sewing tape 19 is bent at the guide pin 21 along the tape supply path shown in FIGS. 1 and 2, and the sewing tape 19 is inserted through the notch 22 formed in the tape guide 22. At the same time, the tip of the sewing tape 19 is positioned between the processing surface 5d and the presser roller 6.

After positioning to the desired sewing position, presser foot lifting lever 1
2, the presser roller 6 is lowered to the position shown in FIG. 2, and the sewing tape 17 and the workpiece W are pressed and held between the workpiece surface 5d of the roller 5 and the workpiece surface 5d. Next, the inverter 30 is actuated based on the operation of an operation pedal (not shown), and an alternating current (20KHz to 50KHz) is applied to the coil 9b.
a. By passing a magnetic flux through the magnetic circuit consisting of the annular body 6b, etc., an eddy current is generated in the annular body 6b, causing the annular body 6b to generate heat, and the motor 14 is started, and the belt 15 and shaft are 16, a belt 17, a presser roller 6 via a shaft 7, etc.
By rotationally driving the workpiece W in one direction, the workpiece W and the sewing tape 19 held between the presser roller 6 and the roller 5 are transferred in one direction as each roller rotates, and the workpiece W is sewn. Wear tape 19

溶着加工を施し得るものである。 At this time, if the amount of depression of the pedal (not shown) is increased and the rotational speed of the motor 14 is increased, the temperature of the annular body 6b is temporarily lowered, and the temperature detection circuit 34 detects that temperature. When a temperature drop signal is detected, the oscillation frequency of the oscillation circuit is lowered based on the comparison result with the optimum temperature setting device, and the amount of heat generated based on the eddy current loss is increased, thereby increasing the temperature of the annular body 6b. The temperature is raised and kept substantially constant, making it possible to perform substantially uniform welding.

９ｂへの通電量を制御するようにしても良い。 In the above embodiment, the surface temperature of the position where the annular body 6b actually generates heat can be detected based on the generation of eddy current due to the energization of the coil 9b. When the heat generation position and the temperature detection position are arranged with a deviation from each other by the rotational angle of the presser roller 6, an angular position detection circuit is provided to detect the rotational angular position of the presser roller 6 in order to detect the deviation angle. The amount of current applied to the coil 9b may be controlled by compensating for the deviation angle.

Furthermore, although an example has been shown in which the output adjustment circuit of the inverter 30 changes its oscillation frequency, it goes without saying that the amplitude of its output voltage may also be adjusted.
