BANDING MACHINE FOR SERIES AND SHUNT COILS OF DC MOTOR STATORS (ACM134)

АСМ134 is a banding machine, designed for the banding tape winding of series and shunt coils for DC motor stators.
The machine frame is made out of aluminum profiles and solid main supporting plate. A supporting bracket is fixed to the machine frame to carry main machine units.
Banding operation is performed by a shuttle, consisting of two half-rings with tooth profile. The half-rings carry the seats for the rolls that guide and wind the banding tape. The shuttle is supported on four rollers. Shuttle angular position and revolutions are controlled by a sensor and the speed of the shuttle rotations is regulated by a pedal that the operator presses during the banding. Two of the supporting rollers are fixed to a slide that is shifted vertically along round guideways by means of a handle. When the slide is in upper position, the half-rings are open to allow loading/unloading of the coil. The coil that is to be processed is placed on the working table and the operator keeps the coil pressed toward the feeding rolls during the banding process.
The banding tape reel is fixed to a hub on the back side of the machine and the tape is passed consecutively through the guiding rollers, the scissors (driven through a pneumatic cylinder) and through the shuttle until it is hooked on the coil. During the rotation the banding tape is pressed toward the shuttle, thus providing constant tape tensioning.
