Definitions

  • the present invention relates to a roving bobbin carrier system including a residual roving removing device according to the preamble of claim 1.
  • the JP-A-60-94628 (Patent Abstract of Japan, Vol. 9, No. 237 (C-305) [1960], 24. Sept. 1985) discloses a residual roving removing device comprising a rotary driving device and a suction hose provided aside said roving bobbin.
  • Such automatic roving bobbin carrier systems disclosed in the former Abstract for conveying the roving bobbins between a group of roving frames and a group of fine spinning frames has been developed to follow automation in the spinning mill.
  • a supply line for supplying the roving bobbins on which the roving is wound is provided between the group of the roving frames and the group of the fine spinning frames
  • a return line for returning the roving bobbins on which the roving is unwound is provided between the two groups as a common line to be used with the supply line or an independent line.
  • a known residual roving removing device (see the latter JP-Abstract) is provided in a part of the return line or a part of a line branched from the return line.
  • a roving bobbin carrier system which includes a device for automatically, converting into blank bobbins any of the roving bobbins on which the residual roving is still attached even after passing through the residual roving removing device.
  • a system of the above kind is characterized by the characterizing features of claim 1.
  • a plurality of roving frames R1, R2, ... and a plurality of fine spinning frames S1, S2, ... are provided in the same shop.
  • a return line 2 for returning a plurality of roving bobbins B1 on which the roving is unwound from the fine spinning frames S1, S2, ... to the roving frames R1, R2, ... in a direction Y1.
  • the return line 2 is provided with a residual roving removing device 50 of a suction nozzle type for removing a residual roving from the roving bobbins B1 and with a backup device 100 for treating or replacing the roving bobbins fed from the residual roving removing device 50, on which roving bobbins the residual roving is still attached, and for supplying the roving bobbins as blank bobbins from which the residual roving is completely removed to the roving frames R1, R2, ...
  • the backup device 100 is located just downstream of the residual roving removing device 50.
  • Fig. 2 which is a perspective view of the backup device 100, it is primarily constructed of a screw conveyor 113, a residual roving sensor 102 and a bobbin replacing device 120.
  • the roving bobbin B1 conveyed by the carrier rail 110 is transferred to the screw conveyor 113, and whether or not a residual roving exists on the roving bobbin B1 is detected by the residual roving sensor 102 located under the screw conveyor 113.
  • the screw conveyor 113 is stopped to stop the roving bobbin B1 at a predetermined position facing the bobbin replacing device 120.
  • the bobbin replacing device 120 includes a vertically movable member 121 and an arm 124 supported on the vertically movable member 121 and adapted to be engaged with a lower surface of an upper flange of the roving bobbin B1.
  • the arm 124 is connected to a cylinder 125 mounted on the vertically movable member 121, and is adapted to be horizontally moved toward and away from the roving bobbin B1 by driving the cylinder 125.
  • the vertically movable member 121 is mounted on a metal or synthetic resin belt 133 wrapped between a pair of rollers 131 mounted at upper and lower ends of a movable rail 130.
  • the movable rail 130 is supported through a plurality of rollers 132 to a fixed frame 135, and is adapted to be vertically moved by a cylinder 134 connected to the lower end of the movable rail 130. Accordingly, when a lower portion 134b of the cylinder 134 is expanded, the movable rail 130 is lowered, and the belt 133 is moved to thereby lower the vertically movable member 121. Thus, the roving bobbin B1 engaging the arm 124 is brought into disengagement from the bobbin hanger BH.
  • the vertically movable member 121 can be moved by a stroke two, three, four, ... times a stroke of the lower portion 134b of the cylinder 134.
  • An upper portion 134a of the cylinder 134 is employed for raising the roving bobbin B1 by a small amount when the roving bobbin B1 is disengaged from the bobbin hanger BH.
  • the blank bobbin storing device 120 includes a circulation rail 150 for storing a minimum number of blank bobbins B2, and the cutter device 160 and the flock roller 142 as mentioned above are also provided to remove the residual roving from the roving bobbin B1 lowered by the bobbin replacing device 120.
  • the backup device 100 may be modified by combining the cutter device with a suction slit type residual roving removing device or by utilizing a chain or belt type bobbin replacing device.
  • the system of the present invention may be modified to the constructions as shown in Figs. 3 and 4.
  • a supply line 3a for supplying the roving bobbins on which a roving is wound is provided between the group of the roving frames R1, R2, ... and the group of the fine spinning frames S1, S2, ... to supply the roving bobbins in a direction X2.
  • a bypass line 2a bypassing a part of the supply line 3a is provided to return the roving bobbins used from the group of the fine spinning frames S1, S2, ... to the group of the roving frames R1, R2, ... in a direction Y2.
  • the residual roving removing device 50 and the backup device 100 are provided in the bypass line 2a, and they are arranged in spaced relationship from each other. Accordingly, the roving bobbins having a residual roving are converted into blank bobbins by the residual roving removing device 50 and the backup device 100 in the course of return to the roving frames R1, R2, ...
  • a plurality of bypass lines similar to the above may be formed, and the residual roving removing device and the backup device may be provided in each of the bypass lines.
  • a common line 5 is provided to convey the roving bobbins from the roving frames R1, R2, ... to the fine spinning frames S1, S2 ... in a direction X3 and vice versa.
  • stock lines 4a and 4b are connected to the common line 5, and the residual roving removing device 50 and the backup device 100 are provided in the stock lines 4a and 4b, respectively, so as to remove the residual roving from the roving bobbins returned from the fine spinning frames S1, S2, ... in a direction Y3 to Y4.
  • the roving bobbins are supplied as blank bobbins to the roving frames R1, R2, ...
  • the residual roving removing device 50 and the backup device 100 may be directly provided in the common line 5 without forming the stock lines 4a and 4b.
