Apparatus for binding thread running through button sewed on garment

An apparatus for winding a binding thread around a button-fixing thread running through a button sewed on a fabric, comprising:

• a base die;
• a motor fixedly mounted on the base die;
• a first spur gear fixedly mounted on a main rotating shaft coupled to the motor;
• a driven shaft having a second spur gear fixedly mounted thereon and connected to the first spur gear by a timing belt, the driven shaft also having a third spur gear fixedly mounted thereto, a fourth spur gear fixedly mounted thereto, and a fifth spur gear fixedly mounted thereto;
• a first actuating shaft connected to the driven shaft, the first actuating shaft being of a hollow structure and having a sixth spur gear fixedly mounted thereon and engaged with the third spur gear;
• a rotating shaft connected to the driven shaft, the rotating shaft having a seventh spur gear connected to the fourth spur gear by a timing belt;
• an eccentric cam fixedly mounted on the rotating shaft;
• a carriage fixedly mounted on the first actuating shaft and operatively connected to the eccentric cam, the carriage serving to convert a rotation of the rotating shaft into an axial reciprocal movement of the first actuating shaft;
• a drum rotatably mounted on the first actuating shaft;
• an eighth spur gear rotatably mounted on the first actuating shaft and connected to the fifth spur gear by a timing belt, the eighth spur gear being attached to the drum, thereby rotating the drum upon a rotation of the first actuating shaft;
• a second actuating shaft axially received in the first actuating shaft, the second actuating shaft being axially fixed with respect to the first actuating shaft while rotating freely;
• means for reversibly rotating the second actuating shaft;
• a thread hooking plate attached to the drum opposite to the eighth spur gear at a desired portion of the periphery of the drum and adapted to hook the binding thread to be wound around the button-fixing thread when the drum rotates;
• a twisting member fixedly mounted to an end of the first actuating shaft protruded from the drum, the twisting member serving to twist the binding thread hooked by the thread hooking plate and to separate the twisted binding thread from the thread hooking plate in accordance with an axial and rotating movement of the first actuating shaft after the thread hooking plate rotates by a predetermined angle;
• a twist forming member fixedly mounted to an end of the second actuating shaft disposed in the vicinity of the twisting member, the twist forming member serving to hook the binding thread twisted by the twisting member in accordance with an axial and rotating movement of the second actuating shaft after the twisting member rotates by a predetermined angle, thereby forming a complete twist with the binding thread;
• a thread separating member arranged in the vicinity of the twist forming member, the thread separating member serving to hook the twisted binding thread on the twist forming member after a predetermined period of time corresponding to a predetermined rotation degree of the twist forming member elapses, thereby separating the twisted binding thread from the twist forming member and winding the binding thread on the button-fixing thread;
• means for reversibly rotating the thread separating member;
• and
• a button holding die arranged in front of the drum and configured to rotate while moving axially to allow a button-fixing thread to run reciprocally through a button held by the button holding die and a garment to be attached with the button.
