Abstract
A transporter is constructed to exchange an empty cloth beam for a full cloth beam of a weaving machine; the cloth being wound into the empty beam while the empty beams remains in the transporter. The transporter has a pair of gripper arm which are automatically acutated in order to transfer a full cloth beam from the weaving machine into the transporter. The gripper arms thereafter move a wind-on beam within the transporter into a position to effect a transfer of the cloth to a fresh cloth beam in the transporter. The gripper arms then move the fresh cloth beam into the weaving machine.
Claims14
A method of changing cloth beams in a weaving mill comprising the steps of
- transferring a full cloth beam from a weaving machine into a predetermined position in a transporter;
- moving a wind-on beam into the path of fabric between the weaving machine and full cloth beam to form a loop of fabric;
- moving the wind-on beam with the loop of fabric about a fresh cloth beam in the transporter;
- cutting the fabric between the fresh cloth beam and full cloth beam;
- positioning a free cut end of the fabric against the fresh cloth beam;
- rotating the fresh cloth beam to wind the fabric thereon over the free cut end of the fabric;
- and
- transferring the fresh cloth beam with the fabric windings thereon to the weaving machine.
A transporter for a weaving mill comprising
- a device for receiving a full cloth beam;
- means for rotatably mounting at least one fresh cloth beam on a fixed axis;
- a wind-on beam;
- and
- gripping arms for moving said wind-on beam between a full cloth beam received in said device and a fresh cloth beam mounted on said means.
A transporter for a weaving mill comprising
- first means for mounting a full cloth beam thereon;
- second means for mounting a fresh cloth beam in parallel relation to the full cloth beam;
- a wind-on beam mounted below said first means;
- a pair of movable gripper arms, said arms being movable from a first position engaging said wind-on beam to a second position positioning said wind-on beam between said first means and said second means to form a loop in a fabric extending from a weaving machine to the mounted full cloth beam, said arms being movable to a third position engaging the fresh cloth beam and to a fourth position positioning the fresh cloth beam in the weaving machine;
- and
- a cutter for cutting the loop of fabric between the mounted full cloth beam and the fresh cloth beam to form a free end of fabric for winding onto the fresh cloth beam.
A transporter for a weaving mill comprising
- first means for mounting a full cloth beam thereon;
- second means for mounting a fresh cloth beam in parallel relation to the full cloth beam;
- a wind-on beam mounted below said first means;
- a pair of movable gripper arms, said arms being movable to lift a full cloth beam out of a weaving machine for mounting on said first means, said arms being movable from a first position engaging said wind-on beam to a second position positioning said wind-on beam between said first means and said second means to form a loop in a fabric extending from the weaving machine to the mounted full cloth beam, said arms being movable to a third position disengaged from said wind-on beam and engaging the fresh cloth beam and to a fourth position positioning the fresh cloth beam in the weaving machine;
- and
- a cutter for cutting the loop of fabric between the mounted full cloth beam and the fresh cloth beam between said second and third positions to form a free end of fabric for winding onto the fresh cloth beam.
