Abstract
Abstract An apparatus for conveying and storing a plurality of wound yarn packages or pirns (spools) which are arranged at spaced intervals on a conveying device of a textile machine. The yarn pirns are moved by the conveyor to a transfer device which transfers them to a transportable storage unit including a plurality of holders for holding wound yarn pirns spaced apart from one another. The transfer device operates cylically. The transfer device grips by means of grippers at least one yarn pirn which has already been conveyed thereto by the conveying device. By moving the grippers, the transfer device conveys the yarn pirn to a holder of the storage unit. Conventional control means are provided for automatically controlling the transfer. The storage unit includes a plurality of rows of holders arranged at different levels with their longitudinal axes inclined with respect to the vertical. The transfer device is constructed in such a way that the grippers are both vertically adjustable and also adapted to be moved obliquely downwards towards the holders of the storage unit in a direction which is inclined with respect to the vertical, this vertically inclined direction of movement corresponding to the inclination of the longitudinal axes of the holders of the storage unit.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
215 words
In an apparatus for transporting and storing a plurality of wound yarn packages, the apparatus including a conveying device of a textile machine on which the yarn packages can be arranged at spaced intervals from one another, the packages being conveyed by the conveying device to a transfer device which transfers them to a transportable storage unit including a plurality of holders for holding wound yarn packages at spaced intervals from one another, the transfer device operating cyclically and upon each cycle gripping by gripper means at least one yarn package which has been brought to the transfer device by the conveying device and which transfers the yarn package to a holder of the storage unit by displacing the gripper means, and control means for automatically controlling the transfer, the improvement comprising, as part of said storage unit, a plurality of rows of said holders which are arranged at different levels with their longitudinal axes inclined with respect to the vertical, and as part of said transfer device, means for both adjusting vertically and moving downwardly said gripper means towards said holders of said storage unit in an obliquely inclined direction to the vertical, this vertically inclined direction of movement corresponding to the inclination of the longitudinal axes of said holders of said storge unit.
Claim 2
Dependent Claim
215 words
In an apparatus for transporting and storing a plurality of wound yarn packages, the apparatus including a conveying device of a textile machine on which the yarn packages can be arranged at spaced intervals from one another, the packages being conveyed by the conveying device to a transfer device which transfers them to a transportable storage unit including a plurality of holders for holding wound yarn packages at spaced intervals from one another, the transfer device operating cyclically and upon each cycle gripping by gripper means at least one yarn package which has been brought to the transfer device by the conveying device and which transfers the yarn package to a holder of the storage unit by displacing the gripper means, and control means for automatically controlling the transfer, the improvement comprising, as part of said storage unit, a plurality of rows of said holders which are arranged at different levels with their longitudinal axes inclined with respect to the vertical, and as part of said transfer device, means for both adjusting vertically and moving downwardly said gripper means towards said holders of said storage unit in an obliquely inclined direction to the vertical, this vertically inclined direction of movement corresponding to the inclination of the longitudinal axes of said holders of said storge unit.
Claim 3
Dependent Claim
19 words
An apparatus as claimed in claim 1, wherein said storage unit is a mobile spool carriage having rigid holders.
Claim 4
Dependent Claim
60 words
An apparatus as claimed in claim 1, including a stationary positioning device, and wherein said rows of holders of said storage unit are offset with respect to each other in a horizontal direction, said storage unit being adjustable by said stationary positioning device during the transfer in a direction parallel to the longitudinal direction of movement of said transfer device.
Claim 5
Dependent Claim
48 words
An apparatus as claimed in claim 1, wherein said transfer device includes a vertically adjustable carriage on which at least One of said gripper means is arranged to be vertically adjustable and moveable in the direction of said holders of said storage unit and is further rotatably arranged.
Claim 6
Dependent Claim
115 words
An apparatus as claimed in claim 4, including a chain drive means provided on said carriage and at least one gripper support being disposed on said carriage said at least one gripper means being pivotably arranged on said gripper support, said chain drive means having an upwardly directed path of motion above said conveying device, this path being adjoined by a path of motion parallel to the longitudinal axes of said holders of said storage unit on which yarn packages are to be placed, the path of motion being defined by at least one guide means for guiding said at least one gripper means in a parallel direction to the longitudinal axes of said holders.
Claim 7
Dependent Claim
46 words
An apparatus as claimed in claim 1, wherein said transfer device includes a plurality of grippers arranged adjacent to each other in a horizontal row, the number of said grippers corresponding to the number of said holders in a row of holders in said storage unit.
