US 5,582,357 A · Coil winding apparatus

Abstract

The invention provides a coil winding apparatus which is simplified in structure, reduced in cost and improved in operation efficiency. The coil winding apparatus comprises a housing intermittently rotatable around a fixed axis between first and second positions, a plurality of spindles mounted for rotation on front and rear faces of the housing, a pair of drive sections including a bidirectional motor and provided independently of each other for transmitting rotation of the motor to rotate the spindles, an insulation sheet supply section opposed to the spindles on one of the faces of the housing when the housing is at any of the first and second positions for supplying films to bobbins mounted on the spindles, and a wire supply section for supplying wires to bobbins mounted on the other spindles. Since the drive sections are provided independently of each other for the different spindles, the directions and the speeds of rotation of the spindles can be set arbitrarily.

Dependent claims

A coil winding apparatus, comprising:

a frame member intermittently rotatable around a fixed axis between first and second positions;
at least one pair of spindles mounted for rotation on opposed faces of said frame member;
a pair of drive means including a bidirectional motor, said drive means corresponding to said spindles each for transmitting rotation of said motor to a corresponding one of said spindles to rotate said spindles independently of each other at an arbitrarily set variable speed;
insulation sheet supply means opposed to one of said spindles when said frame member is at either of the first and second positions for supplying an insulation sheet to a bobbin mounted on the spindle;
and
wire processing means for supplying a wire to another bobbin mounted on the other spindle when said frame member is at either of the first and second positions;
the insulation sheet being wound onto the bobbin mounted on the one spindle while the wire is simultaneously wound onto the bobbin mounted on the other spindle.

A coil winding apparatus, comprising:

insulation sheet supply means for supplying an insulation sheet;
wire supply means for supplying a wire;
a film and wire winding working section for winding the insulation sheet supplied from said insulation sheet supply means and the wire supplied from said wire supply means alternately onto a bobbin;
a spindle provided in said film and wire winding working section for removably mounting a bobbin thereon;
a carrying in/discharging section including a bobbin holding shaft, onto which the bobbin can be removably mounted, for supplying and discharging the bobbin to and from said bobbin holding shaft;
and
an automatic loader section, disposed between said carrying in/discharging section and said film and wire winding working section, which turns between a first position and a second position and including a pair of chucking sections individually opposed to said bobbin holding shaft positioned on said carrying in/discharging section and said spindle of said film and wire winding working section when said automatic loader section is positioned at any of the first and second positions, and control means for controlling said chucking sections to move toward and away from said spindle and said bobbin holding shaft when said automatic loader section is positioned at any of the first and second positions so as to chuck and remove bobbins on and from said spindle and said bobbin holding shaft and mount the thus removed bobbins onto said bobbin holding shaft and said spindle.
