摘要:
A bobbin transport system for spinning frames for supplying bobbins from bobbin reservoirs (R1-R4) to spinning frames (S1-S16) in a spinning mill. The spinning frames are divided into dedicated machine groups (G1, G2) and a common machine group (G12) or groups. Bobbins are supplied to the dedicated machine groups by way of a main transport path (73a) and/or a sub transport path (73b, 73c,73d), and a communicating transport path for transferring bobbins from the sub transport path (73e) to the main transport path (73) is provided for each of the spinning frames of the common machine group or groups. The bobbin transport system for spinning frames makes it possible to change the allotment of numbers of spinning frames for different types of yarns to be set for the common machine group or groups and to distribute different types of bobbins accurately to predetermined spinning frames thereby to enable production of several articles by small quantities without deteriorating the availability factor of the entire spinning frames.

A residual lap clearing apparatus for clearing a residual lap from a lap bobbin. The residual lap clearing apparatus comprises a rotary brush roller (11) for stripping the residual lap off the lap bobbin, a support roller (13) for supporting a lap package for residual lap clearing operation, a brake mechanism (21) for braking the lap package during the residual lap clearing operation, and a comb roller (12) for removing bunches of fibers caught in the bristles of the rotary brush roller off the rotary brush roller. The rotary brush roller (11) surely finds the free end of the residual lap and clears the residual lap perfectly from the lap bobbin.

The present invention relates to a cop feeding apparatus for an automatic winder for feeding cops which are carried on trays and conveyed along a conveyance rail (4) automatically to empty spindle portions of cop magazines (3) in the automatic winder while moving along the conveying rail. In this cop feeding apparatus, a cop is pulled out from a tray by means of a cop draw-out device; a yarn end of the cop is held by a yarn end draw-out device; the cop is then fed to an empty spindle portion of the magazine through a storage device and a retaining/introducting device; a yarn end of the cop is delivered securely to the magazine side by a yarn end guide device; and thus each cop and a yarn end thereof can be fed to an empty magazine spindle portion smoothly without entanglement of cops with each other.

The present invention relates to a remained roving bobbin exchanging device (3) for making all the roving bobbins (1a) to be transported to a roving frame into vacant bobbins (1b) and discloses the remained roving bobbin exchanging device (3) comprising a fixing or removal device (20) for detecting the bobbins having the remained rovings adhered thereto on the bobbin transporting line and exchanging them with vacant bobbins and a tray transporting device (50) for receiving the remained roving bobbins from the fixing or removal device (20) and supplying the vacant bobbins to the fixing or removal device, in which the tray transporting device (50) is made such that a tray can be circulated and at the same time the remained roving cutter device (60) and the remained roving removal device (40) are arranged to remove the remained roving from the remained roving bobbin.
摘要:
A cop sorting and transporting system for a transporting step from spinning machines (S) to winders (W) in a spinning mill. A tab code representative of a type of a yarn of a cop is set arbitrarily to a tab device (TB) provided for each of cop magazines (M) which are provided for accommodating cops therein in order to selectively determine a destination of the cop magazine. The tab code of the tab device (20) can be changed or reset to allow repetitive use of the tab device, which allows common use of the cop magazines to cope with production of many types of spun yarn by small quantities.
摘要:
In a clearer unit for draft rollers arranged to cause endless clearer belts (11, 21) to travel in contact with the peripheral surfaces of the draft rollers, when a roller gauge is to be changed in accordance with a change of a type of fiber yarn, the adjustment of the locations where urging members (13, 23) for urging the clearer belt (11, 21) is made unnecessary by such an arrangement that each of the urging members (13, 23) includes a multiplicity of contact pieces (13b, 23b) the number of which is greater than that of the disposed draft rollers and further the contact pieces (13b, 23b) are disposed along the traveling direction of the clearer belts (11, 21) in a draft zone, so that the clearer belts (11, 21) are pressed against the peripheral surfaces of the draft rollers through these contact pieces (13b, 23b).
