いう問題点を有するものであつた。Prior Art When ultrasonically welding sheet-like processing materials using the conventional apparatus described above, the temperatures of the processing surface of the processing horn and the presser roller at the start of the processing operation are relatively low, and the processing operation cannot be continued continuously. When the ultrasonic welding process is carried out on a regular basis, the frictional heat generated during the ultrasonic welding operation is accumulated on the presser roller and the processed surface, and their temperatures become relatively high. Therefore, if the vibration amount of the processing horn and the transfer speed of the processing material are set so that the welding of the processing material is optimal at the start of the processing operation, when the processing operation is performed continuously, the presser roller As the temperature of the machined surface increases, the material to be processed may become overly welded, and in extreme cases, holes may form in the material, or conversely, the temperature of the presser roller, etc. may rise relatively. If the vibration amount of the machining horn, the transfer speed of the machining material, etc. are set low in advance so as to perform the optimal welding work on the processed material in the state where However, this method had the problem that it could not be applied and it caused problems.

Although something has already been proposed by the applicant,
In these devices, the detection device for detecting the temperature of the presser roller comes into contact with the presser roller, resulting in problems with its durability, and non-contact types have problems such as the cost becoming too high. It was defective.

である。Purpose This invention was made in order to solve the above-mentioned problems, etc., and includes a temperature indicating member that changes its own color in response to changes in the temperature of the presser roller, which is attached to at least a portion of the presser roller. Along with letting
A detection device for detecting a change in the color of the temperature indicating member and an adjustment circuit for adjusting one or both of the vibration amount of the processing horn and the transfer speed of the processing material in response to the detection output from the detection device are provided. By automatically adjusting the amount of vibration of the horn, the transfer speed of the material to be processed, etc. in response to changes in the temperature of the presser roller, it is possible to uniformly weld the material to be processed even if the temperature of the presser roller changes. Moreover, it is an object of the present invention to provide an ultrasonic welding machine whose detection device has a simple configuration and can be realized at low cost.

行うことができる。 Next, the operation of the ultrasonic welding machine configured as above will be explained. First, a sheet-shaped material to be processed is placed on the upper surface of the bed 2 including the processing surface 13 of the processing horn 12, and when the presser roller 25 is lowered by the push-up lever 22, a pressing force is applied to the material to be processed. is held between the processing surface and the presser roller. When a processing start switch such as a foot switch is operated in this state, a high frequency current is supplied to the ultrasonic vibrating element 9 to ultrasonically vibrate the processing horn 12, and the rotation of the motor 15 causes the presser roller 25 to move in one direction. be rotated. For this reason,
Processing horn 1 while processing material is sent in one direction
The welding process is continuously performed between the processed surface 13 of No. 2 and the presser roller 25. In this case, in this ultrasonic welding machine, the photodetector 25 constantly detects the temperature of the outer peripheral surface of the presser roller 25, and generates a detection signal depending on whether or not the temperature exceeds 70°C. In response to this, the amplification degree of the variable amplification degree amplification circuit 36 is controlled, and the amount of vibration of the ultrasonic vibration element 9 is adjusted in accordance with the detection signal. That is, when the outer surface temperature of the press roller 25 and the processing surface 13 is low and the press roller 25 exhibits a red color, the amount of vibration, that is, the amplitude of the ultrasonic vibration element 9 increases accordingly, and the pressure roller and the processing surface 13, the outer surface temperature of the presser roller 2 becomes high.
When the color of the ultrasonic transducer 5 changes from red to brown-purple, the amplitude of the ultrasonic vibration element 9 is controlled to be small. Therefore, the degree of welding of the material to be processed is always maintained constant, and excellent welding can always be performed regardless of the temperature of the outer surfaces of the presser roller 25 and the processing surface 13.

良い。 In the above embodiments, the temperature-indicating member attached to the presser roller is a silicone rubber roller in which a temperature-indicating material is mixed in advance during molding. It is also possible to attach paint or tape, and an example is shown in which only one type of temperature-indicating material is used and a single detector is provided as a detection device to detect the discoloration. However, for example, the roller may have a multilayer structure divided by a plane perpendicular to the axis of rotation of the roller, and each layer may be coated with various temperature-indicating materials that change color at different temperatures. A large number of detectors may be provided to detect the discoloration of each of the temperature indicating members by attaching them to a holding roller for paint, tape, or the like that changes color.

As means for adjusting the degree, for example, it is possible to change the transfer speed of the processed material, or to adjust both the amount of vibration of the ultrasonic vibration element mentioned above and the transfer speed of the processed material. Needless to say.
