Abstract
The invention is concerned with a machine for drawing yarn hanks from advancing hank carrying supports and doffing the drawn hanks on a carriage or container or conveyor belt. The machine comprises a pliers holder head wherein the pliers, each formed of two or more rods movable near one another, can be adjusted in spacing for adaptation to various dimensions of hanks. The head is rotatable about a horizontal axis to arrange the hanks in horizontal direction and is tiltable or upsettable about a further horizontal axis. Furthermore, the head is mounted to be movable parallel to the extension of the hank carrying supports, and preferably also parallel to the advancement or feeding of the hank carrying supports.
Claims31
A machine for removing yarn hanks from hank carriers and for unloading the removed hanks onto container means, said machine comprising:
- plier means for removing yarn hanks from hank carriers, said plier means including a fixed center rod and two side rods, the side rods being movable towards the center rod at the two opposite sides thereof for simultaneous gripping of two hanks and being movable away from said center rod for releasing gripped hanks;
- and
- pliers operating means for controlling said gripping and said releasing movements.
A machine for drawing yarn hanks from hank carriers and for unloading the hanks onto a container means, the yarn hanks hanging on said hank carriers so that yarn threads are in a vertical arrangement on each side of the carrier, said hanks having an exposed lateral surface on two opposed sides thereof, said machine comprising:
- a plier holder head;
- plier means positioned on said head for clamping hanks, said plier means having elements operable between an open condition, in which they are spaced from a hank interposed between them, and a closed condition, in which they clamp a hank interposed between them;
- means for operating said plier means between said open and said closed condition, said plier means when in said closed condition clamping said hank at least along two clamping lines which are substantially transverse to said threads and spaced from each other along the hank sides;
- and
- means for rotating said head about a substantially horizontal axis to bring a clamped hank to a substantially horizontal attitude.
