Abstract
A bobbin stripping unit for removing yarn residues from a bobbin, the bobbin being substantially cylindrical with a longitudinal axis. The bobbin stripping unit includes a holding device which holds the bobbin in a substantially vertical or horizontal position with respect to its longitudinal axis, at least one suction nozzle extending over substantially the entire length of the bobbin for sucking in yarn residues, and a casing which can be transferred between a stripping configuration and a release configuration. In the stripping configuration, the casing substantially surrounds the bobbin, at least partially. In the release position, the casing exposes the bobbin for insertion and removal.
Claims17
A bobbin stripping unit for removing yarn residues from a bobbin, wherein the bobbin is substantially cylindrical with a longitudinal axis, wherein the bobbin stripping unit comprises:
- a holding device which holds the bobbin in a substantially vertical or horizontal position with respect to its longitudinal axis;
- at least one suction nozzle extending over substantially the entire length of the bobbin for sucking in yarn residues;
- and
- a casing which can be transferred between a stripping configuration and a release configuration, wherein the casing in the stripping configuration surrounds the bobbin at least partially and in the release position exposes the bobbin for insertion and removal.
A bobbin stripping arrangement, comprising:
- a plurality of bobbin stripping units, wherein each of the bobbin stripping units comprises:
- a holding device for holding a bobbin in a substantially vertical or horizontal position with respect to a longitudinal axis of the bobbin,
- a suction nozzle extending over substantially the entire length of the bobbin for sucking in yarn residues, and
- a casing which can be transferred between a stripping configuration and a release configuration, wherein the casing in the stripping configuration surrounds the bobbin at least partially and in the release position exposes the bobbin for insertion and removal;
- and
- a control device configured to operate the plurality of bobbin stripping units in a coordinated manner.
A method for operating a bobbin stripping unit, wherein the bobbin stripping unit comprises a holding device for holding a bobbin in a substantially vertical or horizontal position with respect to a longitudinal axis of the bobbin, at least one suction nozzle extending over substantially the entire length of the bobbin for sucking in yarn residues, and a casing which can be transferred between a stripping configuration and a release configuration, the method comprising the steps:
- providing the casing in the release position;
- when the casing is in the release position, transferring a bobbin held by the holding device to a designated working position;
- when the bobbin is arranged at the designated working position, transferring the casing to the stripping configuration, in which the casing substantially surrounds the bobbin;
- when the casing is in the stripping configuration, operating the at least one suction nozzle to suck in yarn residues located on the bobbin;
- upon completing operation of the at least one sucking nozzle, returning the casing to the release position;
- and
- when the casing is returned to the release position, removing the bobbin which is held by the holding device from the working position.
