Bobbin winder at a pneumatic yarn texturizing machine

摘要

The bobbin winder has a programmable robot to take the bobbin sleeves (4a,4b) from fixed supply magazines (15a,15b) and/or align the sleeves over the bobbin drive cylinders (13a,13b) and/or transfer the sleeves at the swing arms (9a,9b) and/or take the fully wound bobbins from the swing arms (9a,9b). The robot is a grip arm, with a movement on a rail system in the X, Y and Z directions over the bobbin drive cylinders (13a,13b), and has a swing grip hand (16) on a vertical axis in the Z direction. The grip hand (16) has two swing grip pads (17,18). An additional drive rotates the full bobbin, which is lifted from its drive cylinder (13a,13b) by the swing arms (9a,9b), activated by the robot, and is near the swing arms. The swing arm (9a,9b) has rotating clamping disks (10a,10b,11a,11b), with the fully wound bobbin fixed between them, and rotated by the drive. The robot has a mechanism to located and fix the end of the fully wound yarn by a stapled clip or by an adhesive tape drawn from a dispenser. A cutter (19), at the robot, cuts the yarn link between the full bobbin and the yarn feed at the bobbin winder (2a,2b). The cutter (19) has one arm of the shears, pressed against the other for the cutting action against a spring. A single robot serve a number of pneumatic yarn texturizing machines (1a,1b). The fixed supply magazines (15a,15b) for the bobbins sleeves (4a,4b) are charged by the robot from a central sleeve supply station.
