Miscellaneous Spare parts

  The 1250 Automatic Traverse can be interfaced to the 1201 series Bobbin Winders to automatically lay the wire into the work piece by traversing back and forth relative to the wire diameter and speed of the bobbin winder. This eliminates the operator from having to hand lay the wire onto the work piece. The 1250 Automatic Traverse is physically mounted on the 1217 baseplate and located to the right and slightly behind the winder. The wire is tensioned controlled by a dereeler located behind the traverse and fed over the traverse's wire support arm unto the workpiece. The 1250 Automatic Traverse uses a high precision stepper motor with a powerful microprocessor which provides high precision settings and movement controls to provide excellent layering capability. The traverse is easily set up by simply setting the wire diameter (pitch) and the traverse length by thumbwheel switches and establishing the home(s) and starting traverse direction. The number of turns and speed are established by the bobbin winder. It’s that simple. Flexible tooling for wire feeding allows for multiple bobbins to be wound at the same time to increase your production output.

 

THEORY OF OPERATION

 The 1250 Automatic Traverse uses a photoelectric pick up which senses rotation and direction of the bobbin winder. In the basic operation mode every rotation or fraction thereof, the traverse carriage moves a specific distance as specified by the “Pitch” setting. The carriage will continue travel in one direction until it reaches the distance specified in the “Length” setting upon which it will reverse direction. It will continue in this manner until the number of turns are reached as programmed on the bobbin winder. The initial home position and directions are set by the operator. Additional built in programs allow several winding modes including layer winding, multi-home, variable pitch, variable layering and prototyping universal winding.

1250 Automatic Traverse Accessories


1228 Wire Guide Assembly

Mounts directly to the vertical post on the carriage assembly to guide wire from the dereeler to the work piece. The adjustable wire guide consists of two high strength nylon pulleys and a wire grip.


1240 Wire Tube

A small diameter tube that is mounted in place of the bottom pulley on the Wire Guide Assembly to allow fine wire to be positioned close to the work piece for better layering control.


1243 Guide Rail

Used with the 1244 Holders to provide a platform to mount several 1228 Wire Guide Assemblies for multiple bobbin winding applications. The Guide Rail replaces the vertical mounting post on the carriage assembly of the Traverse.

 1244 Holders

Multiple Holders can be mounted to the 1243 Guide Rail allowing multiple 1228 Wire Guide Assemblies to be installed, to wind several bobbins at the same time.

Dereelers

Provide tension on the wire during the winding process. A spool of wire is placed on the base of the dereeler and the wire feeds through a series of spring tensioning rings and pulleys. A variety of dereelers are available according to the range of wire size and spool diameter.

Wisker Disks

Placed on top of wire spools, they work as a pre-tensioner and to keep the wire at a controlled path.
