Abstract
The invention relates to a button delivery system and features improvements in three major areas, the button feeding mechanism for feeding buttons to the sewing machine, a button supply system for supplying buttons to the button feeding mechanism, and a support for positioning the button feeding mechanism with respect to the sewing machine for the smooth transfer of buttons into the sewing machine.
Claims14
In a button feeding mechanism for feeding buttons to a clamp on a raised arch of a sewing machine wherein the button feeding mechanism comprises a frame, driving means mounted on said frame, a first rod mounted on said frame for reciprocal movement and having an initial position, coupling means for coupling said driving means to said first rod selectively to move said first rod from its initial position through a cycle of movement, orienting means mounted on said frame for orienting a button and coupled to said first rod, a second rod coupled to said first rod and mounted on said frame for reciprocal motion, and moving means coupled to said second rod for moving a button through the orienting means to the clamp of said sewing machine, the improvement comprises said coupling means comprising a clutch controlled by an electrical circuit energized by the simultaneous condition of the arch of said sewing machine being in its raised position subsequent to being in its lowered position and said first rod being in its initial position.
A button supplying system for supplying buttons to a button feeding mechanism for a sewing machine, comprising
- hopper for holding a plurality of buttons;
- a first chute connected to said hopper for receiving buttons discharged from said hopper;
- means to discharge buttons having a predetermined orientation from said hopper to said first chute;
- a second chute connected to said first chute and said button feeding mechanism for directing buttons from said first chute to said button feeding mechanism;
- means controlling the transfer of a button from said first chute to said second chute and responsive to an electrical signal;
- and
- means connected to said sewing machine for producing said electrical signal in said controlling means when said sewing machine is in a predetermined operating position.
A support for positioning a button feeding mechanism near a sewing machine for the smooth feeding of buttons from said button feeding mechanism into said sewing machines;
- said support comprising;
- mounting means comprising a base and means for connecting said base to a surface so that a portion of said base is moveable parallel to said surface or so that said base is fixed with respect to said surface;
- a first component comprising a cylindrical portion connected to and extending vertically from the portion of said base which can be moveable;
- a cylindrical collar engaging said cylindrical portion, and comprising means to fix its position axially and rotationally with respect to said cylindrical portion and a first extended portion for fixing the rotational position of said button feeding mechanism;
- a second component having a cylindrical opening and engaging said cylindrical portion, said second component supported by said cylindrical collar and comprising means to fix its angular position with respect to said cylindrical portion and a second extension which engages said first extension to define the angular position of said second component by the angular position of said cylindrical collar;
- a third component connected to said second component and comprising a cylinder mounted for both axial and rotational movements with respect to said third component and having its axis generally parallel to said surface, and means to fix the position of said cylinder both axially and rotationally with respect to said third component;
- and
- means for connecting said cylinder to said button feeding mechanism so that said button feeding mechanism is rotatable around an axis parallel to said surface or said button feeding mechanism can be fixed with respect to said surface.
A sewing machine system comprising
- a sewing machine;
- a button feeding mechanism for feeding buttons to a clamp on a raised arch of said sewing machine comprising a frame, driving means mounted on said f rame, a first rod mounted on said frame for reciprocal movement and having an initial position, coupling means for coupling said driving means to said first rod selectively to move said first rod from its initial position to a cycle of movement, orienting means mounted on said frame for orientinq a button and coupled to said first rod, a second rod coupled to said first rod and mounted on said frame for reciprocal motion, moving means coupled to said second rod for moving a button through the orienting means to the clamp of said sewing machine, and an electrical circuit for energizing said coupling means by the simultaneous condition of the arch of said sewing machine being in its raised position subsequent to being in its lowered position and said first rod being in its initial position;
- a button supplying system for supplying buttons to said button feeding mechanism comprising a hopper for holding a plurality of buttons;
- a first chute connected to said hopper for receiving buttons discharged from said hopper;
- means to discharge buttons having a predetermined orientation from said hopper to said first chute;
- a second chute connected to said first chute and said button feeding mechanism for directing buttons from said first chute to said button feeding mechanism;
- means controlling the transfer of a button from said first chute to said second chute and responsive to an electrical signal;
- and means connected to said sewing for producing said electrical signal into said controlling means when said sewing machine is in a predetermined operating position;
- and
- a support for positioning said button feeding mechanism near said sewing machine for the smooth feeding of buttons from said button feeding mechanism into said sewing machine;
- said support comprising mounting means including a base and means for connecting said base to a surface so that a portion of said base is moveable parallel to said surface or so that said base is fixed with respect to said surface;
- a first component comprising a cylindrical portion connected to an extending vertically front the portion of said base which can be moveable;
- a cylindrical collar engaging said cylindrical portion, and comprising means to fix its position axially and rotationally with respect to said cylindrical portion and a first extended portion for fixing the rotational position of said button feeding mechanism;
- a second component having a cylindrical opening and engaging said cylindrical portion, said second component supported by said cylindrical collar and comprising means to fix its angular position with respect to said cylindrical portion and a second extension which engages said first extension to define the angular position of said second component by the angular position of said cylindrical collar;
- a third component connected to said second component and comprising a cylinder mounted for both axial and rotational movements with respect to said third component and having its axis generally parallel to said surface, and means to fix the position of said cylinder both axially and rotationally with respect to said third component;
- and means for connecting said cylinder to said button feeding mechanism so that said button feeding mechanism is rotatable around an axis parallel to said surface or said button feeding mechanism can be fixed with respect to said surface.
