Description
- 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-62-62932 Patent Abstract of Japan Vol. 11 No. 262 (C-442) (2709), 25. August 1987, discloses a roving bobbin carrier system of the above kind having a supply line and a return line for roving bobbins and a roving removing device.
- 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. For example, 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, and 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.
- However, a residual roving is attached on most of the roving bobbins to be returned to the roving frames, and such roving bobbins cannot be used in the roving frames as they are.
- Accordingly, 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.
- However, as an amount of the residual roving attached on the roving bobbins to be returned from the fine spinning frames is indefinite, all of the residual roving cannot be removed by the residual roving removing device, and there sometimes occurs that the roving bobbins on which the residual roving remains attached are fed downstream of the residual roving removing device. Accordingly, an operator must replace the roving bobbins having the residual roving with blank bobbins, thus hindering automatic conveyance of the roving bobbins.
- It is therefore the object of the present invention to provide 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. To comply with this object, a system of the above kind is characterized by the characterizing features of
claim 1. - Fig. 1 is a schematic illustration of the carrier system according to a first preferred embodiment of the present invention;
- Fig. 2 is a perspective view of another preferred embodiment of the backup device according to the present invention;

- Fig. 4 is a schematic illustration of the carrier system according to a third preferred embodiment of the present invention.
- Referring to Fig. 1 which is a schematic plan view of a general construction of the roving bobbin carrier system according to a first preferred embodiment of the present invention, a plurality of roving frames R₁, R₂, ... and a plurality of fine spinning frames S₁, S₂, ... are provided in the same shop. There are provided between a group of the roving frames R₁, R₂, ... and a group of the fine spinning frames S₁, S₂, ... a
supply line 3 for supplying a plurality of roving bobbins B₀ on which a roving is wound from the roving frames R₁, R₂, ... to the fine spinning frames S₁, S₂, ... in a direction X₁ and areturn 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. Thereturn line 2 is provided with a residualroving removing device 50 of a suction nozzle type for removing a residual roving from the roving bobbins B₁ and with abackup device 100 for treating or replacing the roving bobbins fed from the residualroving 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, ... Thebackup device 100 is located just downstream of the residualroving removing device 50. - Referring to Fig. 2 which is a perspective view of the
backup device 100, it is primarily constructed of ascrew conveyor 113, aresidual roving sensor 102 and abobbin replacing device 120. The roving bobbin B₁ conveyed by thecarrier rail 110 is transferred to thescrew conveyor 113, and whether or not a residual roving exists on the roving bobbin B₁ is detected by theresidual roving sensor 102 located under thescrew conveyor 113. When the existence of the residual roving is detected, thescrew conveyor 113 is stopped to stop the roving bobbin B₁ at a predetermined position facing thebobbin replacing device 120. - The
bobbin replacing device 120 includes a verticallymovable member 121 and anarm 124 supported on the verticallymovable member 121 and adapted to be engaged with a lower surface of an upper flange of the roving bobbin B₁. Thearm 124 is connected to acylinder 125 mounted on the verticallymovable member 121, and is adapted to be horizontally moved toward and away from the roving bobbin B₁ by driving thecylinder 125. The verticallymovable member 121 is mounted on a metal orsynthetic resin belt 133 wrapped between a pair ofrollers 131 mounted at upper and lower ends of amovable rail 130. Themovable rail 130 is supported through a plurality ofrollers 132 to afixed frame 135, and is adapted to be vertically moved by acylinder 134 connected to the lower end of themovable rail 130. Accordingly, when alower portion 134b of thecylinder 134 is expanded, themovable rail 130 is lowered, and thebelt 133 is moved to thereby lower the verticallymovable member 121. Thus, the roving bobbin B₁ engaging thearm 124 is brought into disengagement from the bobbin hanger BH. The verticallymovable member 121 can be moved by a stroke two, three, four, ... times a stroke of thelower portion 134b of thecylinder 134. Anupper portion 134a of thecylinder 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. - There are provided under the bobbin replacing device 120 a residual roving removing device and a blank bobbin storing device as shown in Fig. 2, so as to replace the roving bobbin B₁ having a residual roving as released from the bobbin hanger BH with a blank bobbin B₂.

circulation rail 150 for storing a minimum number of blank bobbins B₂, and thecutter device 160 and theflock roller 142 as mentioned above are also provided to remove the residual roving from the roving bobbin B₁ lowered by thebobbin 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. - Although the residual
roving removing device 50 and thebackup device 100 are provided in thereturn line 2, and they are juxtaposed to each other in the first preferred embodiment, the system of the present invention may be modified to the constructions as shown in Figs. 3 and 4. - Referring to Fig. 3 which shows another preferred embodiment of the present invention, 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. Furthermore, abypass line 2a bypassing a part of thesupply 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 residualroving removing device 50 and thebackup device 100 are provided in thebypass 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 residualroving removing device 50 and thebackup device 100 in the course of return to the roving frames R₁, R₂, ... In the case of forming a plurality of different return lines for different kinds of rovings, 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. - Referring to Fig. 4 which shows a further preferred embodiment of the present invention, a
