BRAKE STRUCTURE OF BAND REEL IN PACKING MACHINE

摘要

It is an object to provide a brake structure of a band reel in a packing machine in which reliable braking effects can be obtained and responsiveness can be enhanced. In a brake structure provided on a reel shaft for being rotated integrally with a band reel, a brake arm (15) having a coil spring portion (16) provided on one of ends and a band passing ring portion (18) provided on the other end is provided on one of ends of the reel shaft (13) and one of ends on the coil spring (16) side in the brake arm (13) is fastened to a fixing member such as a device frame, and a diameter of the coil spring portion (16) is reduced to closely engage an inner peripheral surface of the coil spring portion (16) with an outer peripheral surface of the reel shaft (13), thereby stopping a rotation of the reel shaft by frictional force, when the force for feeding the band is released.
