In the one described in Japanese Patent No. 325, the axis of the thermoplastic material (rubber belt) is aligned according to the operator's sensation, so that the joint portion of the thermoplastic material (rubber belt) is connected to the shaft of the thermoplastic material. In order to remove this protrusion, the parts that have been heated and melted protrude (raise) in the direction orthogonal to the axis of the thermoplastic material when they are pressed against each other because they cannot be joined straight Post-processing is required. Also, since the operator presses the joint part, the amount of protrusion (heap amount) of part of the material melted by heating is
The quality of each thermoplastic is different because it is different for each joining. In the one disclosed in Japanese Utility Model Laid-Open No. 4-89325, by moving the actuators individually, both ends of the thermoplastic material held by each chuck are joined to each other by pressing a heating body or both ends thereof against each other. . Therefore, as many actuators as chucks are required, and each actuator has both end portions of the thermoplastic material pressed against the heating body to melt a certain amount, or when both end portions are pressed against each other and joined to each other, they are delicate. Movement is required. Furthermore, the actuator used only for moving the chuck is expensive and takes up space when it is installed in the thermoplastic joining machine, and an air source is required for its movement, so the joining machine itself becomes expensive and large. Become a trend.

While extending the spring 22, the chucks 3, 3 and the slide bases 15, 15 are separated from each other.
The movable support plate 27 of the support 25 is maintained while maintaining this separated state.
Is rotated until the position of the protrusion amount regulating means 4 is positioned between the chucks 3, 3 and the slide bases 15, 15. At this time, the movable support plate 27 is rotated toward the protrusion amount restricting means 4 side in a state where the slide bases 15 and 15 are separated from each other, so that the spherical body 32C of the rotation stopping mechanism 32 resists the spring force of the coil spring 32B. Then, it is automatically removed from the recess 32A facing the heating amount regulating means 6 and the lock by the detent mechanism 32 is released. In addition, the sphere 3 of the rotation stopping mechanism 32
2C automatically fits into the recess 32A facing the protrusion amount restricting means 4 against the spring force of the coil spring 32B, and locks the movable support plate 27. Then, the movable support plate 27 cannot rotate at the position of the protrusion amount restricting means 4.

As shown in FIG. 5, when they are moved toward each other,
The pressing margins 2b of the thermoplastic rope 2 protruding from the chucks 3, 3 are joined together while pressing together with the melting portion (melting margin 2a) melted by the heating body 5. At this time, both ends 2A, 2B of the thermoplastic rope 2 protruding from each chuck 3 are melted by the heating body 5 while making their mutual axes b, b on the same axis. As a result, the two ends 2A, 2B of the thermoplastic rope 2 protruding from each chuck are
The preload springs 22 are evenly distributed to the chucks 3, 3 so that they are joined with the same amount of joining (the amount of protrusion of the thermoplastic rope 2 protruding from each chuck 3, 3). The amount of protrusion after joining can be controlled by adjusting the spring force of the preload spring 22 during preload. That is, the amount of protrusion of the preload spring 22 after joining due to the spring force during preload can be made equal to the amount of joining by the joining restricting means. Further, both end portions 2A and 2B of the thermoplastic rope 2 protruding from the chucks 3 and 3 are elastically distributed by the preload springs 22 evenly distributed to the chucks 3 and 3 by the preload spring force. It is possible to reduce the protrusion (rise) of the molten portion in the direction orthogonal to the axes b of the rope 2 and to join the ropes. Further, by adjusting the spring force of the preload spring 22 during preload, the thermoplastic rope 2
It is possible to further reduce the protrusion (swelling) of the melted portions in the direction orthogonal to the axes b of the thermoplastic ropes 2 and the melted portions pressed against each other in the above joining can be joined together. In addition, as shown in FIG.
From the slide levers 16, 16 have the same distance in the direction in which the slide levers 16 and 16 are separated from each other, and when the slide levers 16 and 16 are separated by the same distance m, the pressing force restriction means 40 for restricting the movement thereof. 40 (shown by a chain double-dashed line in FIG. 5) may be provided. In this way, the slide levers 16 and 16 are pushed to the pressing force regulating means 40 and 4 respectively.
If they are separated from each other until they are regulated by 0, the preload spring 2
Since 2 is also extended by the same amount in the direction away from each plane 17, 17, both ends 2 of the thermoplastic rope 2
When joining A and 2B, slide levers 16 and 16
When they are separated from each other, the same spring force is applied to each of the chucks 3 and 3, so that both ends 2A and 2B of the thermoplastic rope 2 can be joined with the same pressing force. Further, by making the pressing force regulating means 40, 40 variable in the sliding direction, the distances m, m of the slide levers 16, 16 can be changed to the same desired distance, so that the preload spring 22 is provided. The same spring force acts on each of the checks 3 and 3 stretched at the same distance after the change, and both ends 2A and 2B of the thermoplastic rope 2 are applied.
