Model 307 Stick Winder
with programmable paper feed
Model 307 stick winder is a newly designed machine for winding paper
section coils. Its design is based on the popular Model 107 with
many improvements. The most significant being the use of modern CNC
controls. The use of servomotors has eliminated all of the cams and
linkages that were used to operate the automatic paper feed system.
machine is designed to wind all types of paper section multiple
stick wound coils. The quantity of coils can range from 6 to 52 per
stick. The length of a stick can vary from approximately 22 to 38
inches. These coils are typically wound side by side on a common
paper tube. The coils have alternate layers of wire and paper. The
paper is fed automatically on the fly as each layer of wire is
spindle is driven by a brushless servomotor. The motor is coupled to
the spindle by a belt and pulley set. Mounted on the spindle is an
electromagnetic brake that is used to hold the spindle in position
when the motor stops. An encoder is mounted on the spindle to give
position information. It is used for calculation of turns in .01
increments and to provide data for traverse pitch calculation.
linear traverse system moves a wire guide bar that guides multiple
wires. A brushless servomotor drives the traverse through a zero
backlash lead screw. The traverse can be freely programmed to move
to any position. During winding the traverse pitch rate is precisely
synchronized to the rotation of the spindles and can be changed any
number of times. Pitch rate is calculated to .000001 inch accuracy.
machine runs two programs, one to control the spindle and traverse
for winding the coil. The other program is used to control all of
the paper feed motions. The winding program is synchronized to the
paper feed at each occurrence of the traverse direction change at
the end of a layer.
paper feed system is fully automatic and operates under computer
control. Brushless servomotors are used for the paper measure and
feed shelf positioning. Microstepping stepper motors are used to
raise the complete paper feeder and to fire the paper into the coil.
The paper feed program can sequentially increase the length of paper
as the coil size increases. The complete paper feeder can be
positioned to achieve the best angle for paper insertion.
machine is easily programmed using our CoilPro software. Using
the graphical user interface of Microsoft Windows, all parameters
for the coil are entered in a program builder screen. Parameters for
wire diameter or pitch, number of turns, length of layer, length of
paper, feed shelf position, wind speed etc. are easily entered.
The multi-media and job folder features of CoilPro also allow production and process information to be entered. The program may include material information, drawings, instructions etc. The instructions can include text, audio, pictures, and videos to train the operator and insure quality.
