(1) first bonding pattern: if push down on the pedal 44, then can be stepped on signal input control portion 16, drive motors 17,21 is made to start to rotate, upper and lower a pair endless belt 8,9 is controlled in high-speed mobile, meanwhile, as shown in Fig. 7 (A) and Fig. 8, Fig. 9, the upper roll 10 in roller arrangement 12 drops to the position close with lower rollers 11 by roller elevating mechanism 25, further, upper electrode 13 drops to the position close with lower electrode 14 by electrode lifting mechanism 24.
In this state, place the machined material H be supported on placement plate 5, slide plate 6, operation panel 7 to be clamped between above-mentioned upper and lower a pair endless belt 8,9 also at a high speed to bond processing direction X straight line continus convergence, simultaneously, between upper electrode 13 and lower electrode 14 time, between upper electrode 13 and lower electrode 14, apply the high-frequency electrical of setting from high-frequency electrical bringing device 15, the thermoplastic resin band T of machined material H is melted by high-frequency induction heating.Afterwards, when the machined material H of the thermoplastic resin band T containing fusing passes through between the pair of rolls up and down 10,11 of roller arrangement 12, machined material H is pressed, the bonding agent of the thermoplastic resin band T of fusing is impregnated into docking end or the overlapping portion of fabric lining W, W, thus fabric lining W, W are bonded.Before the bonding release of linearity based on this first bonding pattern, above-mentioned pedal 44 keeps the state stepped on always, when lifting pedal 44 after bonding release, to lift signal input control portion 16 and drive motors 17,21 is stopped the rotation, upper and lower a pair endless belt 8,9 stops.
(2) second bonding patterns: if carry out making operation to knee control switch 45, then by its connection signal input control portion 16, make roller elevating mechanism 25 action thus, so that as shown in Fig. 7 (B), the upper roll 10 of roller arrangement 12 rises to the position upwards leaving lower rollers 11.Afterwards, by pushing down on the pedal 44, signal input control portion 16 will be stepped on, make electrode lifting mechanism 24 action thus, intermittent lifting with the upper push part 31 of this electrode lifting mechanism 24 moves, as Fig. 7 (C) and Figure 10, shown in Figure 11, upper and lower a pair endless belt 8, 9 and a part of machined material H be repeatedly shifted up and down off and on, repeatedly be shifted corresponding with this, upper electrode 13 is elevated off and on upwards leaving between the position of lower electrode 14 and the position close to lower electrode 14, simultaneously, drive motors 17, 21 start to rotate, so that by upper and lower a pair endless belt 8, 9 control to move at low speed.In this state, place be supported on place plate 5, slide plate 6, machined material H on operation panel 7 are sandwiched between above-mentioned upper and lower a pair endless belt 8,9 and low speed is carried to bond processing direction X, simultaneously, between upper electrode 13 and lower electrode 14 time, whenever upper electrode 13 drops to the position close with lower electrode 14 off and on, high-frequency electrical bringing device 15 just applies the high-frequency electrical of setting off and between upper electrode 13 and lower electrode 14, thus melts the thermoplastic resin band T of machined material H by high-frequency induction heating.In this second bonding pattern, because the translational speed of the machined material H being clamped in conveying between upper and lower a pair endless belt 8,9 is low speed, therefore, although apply high-frequency electrical off and on, thermoplastic resin band T still can continuous melting incessantly on the X of bond processing direction, the bonding agent of thermoplastic resin band T can be impregnated into the docking end of fabric lining W, W or the whole region of overlapping portion equably, thus can reliably, bondable fibers fabric W, W securely.
In addition, in the second bonding pattern, upper roll 10 remains on the position rising to and upwards leave lower rollers 11, contact on machined material H is applied to than little during the first bonding pattern when upper electrode 13 rises to the position upwards leaving lower electrode 14 off and on, therefore, whenever the moment that this contact diminishes, the all hand-holdable machined material H of operating personnel is to any direction rotating operation, machined material H is made gradually to change direction to be easy to realize curve conveying, thus can march wire position simply exactly bonding.
After completing bonding action, by lifting pedal 44 and this being lifted signal input control portion 16, thus it is mobile that upper and lower a pair endless belt 8,9 is stopped.Then, again push down on the pedal 44, by this being stepped on signal input control portion 16, upper electrode 13 and upper roll 10 rise.In this state, can take out from high-frequency sewing-machine 1 and bonded the docking end of fabric lining W, W or the fabricated product of overlapping portion by thermoplastic resin band T.
The first bonding pattern and the setting of the high-frequency electrical put on during the second bonding pattern between upper and lower pair of electrodes 13,14 refer to sensed heating pair of electrodes 13,14 melting heat plastic resin band T and make the docking end of fabric lining W bonding required and enough value.This value presets according to the heat resistance etc. of the fabric lining W as bond processing object.Especially, when high-frequency electrical puts on the second bonding pattern between upper electrode 13 with lower electrode 14 off and on, the bonding force on the overlapping portion of fabric lining or docking end is easy to bonding force during the first bonding pattern being applied between upper electrode 13 with lower electrode 14 continuously lower than high-frequency electrical.In order to address this problem, that is in order to bonding force when keeping the second bonding pattern is identical with bonding force during the first bonding pattern or substantially identical, wish by the transporting velocity of the machined material H of a pair endless belt 8,9 realization lower than transporting velocity during the first bonding pattern, and the value of the high-frequency electrical of applying is set as than value slightly large during the first bonding pattern.
Wherein, suitably use can be regulated according to the kind etc. of such as fabric lining by the transporting velocity of the machined material H of a pair endless belt 8,9 realization.For this reason, when have adjusted the transporting velocity of machined material H, regulating according to this speed, also the output of high-frequency electrical being regulated arbitrarily by above-mentioned Drazin inverse portion 43.Like this, whether the transporting velocity regardless of machined material H regulates, all can guarantee that bonding force is identical or substantially identical all the time, simultaneously, during the second bonding pattern that can be separated off and at upper electrode 13, lower electrode 14, prevent from producing spark between upper electrode 13, lower electrode 14 and damaging fabric lining.
