Abstract
Description
- The present invention relates to a roving bobbin carrier system for supplying roving bobbins on which a roving is wound at a roving frame to a fine spinning frame in a spinning mill and simultaneously returning roving bobbins on which the roving is unwound at the fine spinning frame as blank bobbins to the roving frame.
- An automatic roving bobbin carrier system 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 residual roving removing device is provided in a part of the return line or a part of a line branched from the return line. Various types of such a residual roving removing device are known. In one type, a running flock belt is provided to contact the roving bobbins suspended by bobbin hangers for conveying the roving bobbins in the carrier system. In another type, the roving bobbins are released from the bobbin hangers, and are moved near suction slits extending in an axial direction of the roving bobbins to suck the residual roving and unwind the same. Normally, these types of the residual roving removing devices are constructed to collectively treat several to several tens of roving bobbins.
- 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 an object of the present invention to provide a roving bobbin carrier system which can efficiently and continuously remove a residual roving attached on the roving bobbins to be conveyed in the return line to the roving frame by using a residual roving removing device capable of efficiently removing the residual roving in a short time.
- It is another 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.

- 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 Figs. 2 and 3 which are a partially cut-away side view of the residual
roving removing device 50 and a partially cut-away top plan view of Fig. 2, respectively, the roving bobbins B₁ having a residual roving R are suspended by a plurality of bobbin hangers BH, and are carried into the residualroving removing device 50. Under the condition, the roving bobbins B₁ are once stopped. Arotary driving device 51 is provided under each of the roving bobbins B₁. Therotary driving device 51 includes a verticallymovable pin 51a to be inserted into a lower hollow portion of the roving bobbin B₁, arotary driving portion 51b connected to thepin 51a, and acontrol motor 51c connected to therotary driving portion 51b for controllably driving the same, so that a rotational speed of therotary driving portion 51b may be changed. - A plurality of
suction nozzles 52 of the same number as the roving bobbins B₁ are provided aside the roving bobbins B₁ in such a manner as to be movable vertically and horizontally toward and away from the roving bobbins B₁. Anelongated retainer box 53 is provided to retain thesuction nozzles 52 in such a manner that thesuction nozzles 52 project toward the roving bobbins B₁. Theretainer box 53 is horizontally movably mounted on aguide rail 60, and is driven by ascrew shaft 61 and a drivingmotor 62 in such a horizontal direction as to advance toward and retract from an array of the roving bobbins B₁. Theguide rail 60 is mounted on a verticallymovable support 55 which is connected to anendless chain 56. Theendless chain 56 is connected to adriving motor 57. Accordingly, theretainer box 53 is vertically moved by normally or reversely rotating the drivingmotor 57. - Referring to Fig. 5 which shows a construction of the
suction nozzle 52, afront end portion 52a of thesuction nozzle 52 is movably engaged with a front portion of theretainer box 53 through apacking 53a in such a manner as to advance toward and retract from the respective roving bobbin B₁. Ahollow bracket 80 is engaged with a rear portion of theretainer box 53, and a rear end portion 74 of thesuction nozzle 52 is slidably inserted into thehollow bracket 80. A pressure air inducing portion 76 is formed in anintermediate portion 77 between thefront end portion 52a and the rear end portion 74. The intermediate portion 76 is formed at its outer circumference with acontinuous groove 78 engaging apawl 75. The pressure air inducing portion 76 is connected through aflexible hose 72 to apressure air duct 71, so that a pressure air is supplied from thepressure air duct 71 through theflexible hose 72, and is injected from the pressure air inducing portion 76 toward the rear end portion 74 of thesuction nozzle 52. As a result, a suction air flow due to a negative pressure is generated at thefront end portion 52a of thesuction nozzle 52, and an end of the residual roving R on the roving bobbin B₁ is sucked into thesuction nozzle 52. A nozzle portion of the pressure air inducing portion 76 is preferably inclined at a suitable angle such that the suction air flow is rotated in an untwisting direction of the residual roving R on the roving bobbin B₁, so that the residual roving R is changed into an untwisted fiber Ra as shown in Fig. 4, and the untwisted fiber Ra is discharged through asuction hose 54a connected with thebracket 80 to a collecting device (not shown). - In removing the residual roving on the roving bobbln B₁ by using the residual
roving removing device 50 as mentioned above, theretainer box 53 is first moved toward the array of the roving bobbins B₁ in such a manner that thefront end portions 52a of some of thesuction nozzles 52 advance to contact the blank bobbins, if any, and in this case, thefront end portions 52a of theother suction nozzles 52 contacting the roving bobbins having the residual roving are retracted in theretainer box 53. Such a retracted position of thesuction nozzles 52 is maintained by the engagement of thepawl 75 with thecontinuous groove 78. Then, theretainer box 53 is retracted by a distance of 5 - 10 mm, and is then vertically moved as rotating the roving bobbins B₁ at low speeds, thus sucking the end of the residual roving into thesuction nozzles 52. Then, as shown in Fig. 2, theretainer box 53 is further retracted to aposition 53d, and the roving bobbins B₁ are rotated in an unwinding direction of the residual roving R at high speeds, thus removing the residual roving R from the roving bobbins B₁. - The construction of the residual
roving removing device 50 is not limited to the above. For example, the vertical movement and the horizontal movement of thesuction nozzles 52 may be effected by any other known moving means. Further, thesuction nozzles 52 may be connected to a vacuum pump or the like. As to the method of removing the residual roving, a method of re-removing a residual roving on a flock belt of each roving bobbin may be added, or a method of detecting a residual roving amount with use of a residual roving sensor may be combined with the above-mentioned removing method. - Referring to Fig. 6 which is a partially cut-away side view of the
backup device 100, the roving bobbin B₁ suspended by the bobbin hanger BH is carried along acarrier rail 110 in a direction perpendicular to a plane of the sheet of the drawing. A residual roving sensor (not shown) such as an ultrasonic sensor or an optical sensor is provided to detect whether or not a residual roving still exists on the roving bobbin B₁. When the existence of the residual roving is detected, the movement of the roving bobbin B₁ is temporarily stopped. A lower supportingdevice 103 is provided just under the roving bobbin B₁ to be stopped in thebackup device 100. The lower supportingdevice 103 is formed at its upper end with apin 101 to be inserted into the lower hollow portion of the roving bobbin B₁. On the other hand, one or twofixed rollers 116 and one or twomovable rollers 115 which can be moved toward and away from the roving bobbin B₁ by acylinder 114 are provided at a position corresponding to an upper portion of the roving bobbin B₁, thus supporting the upper portion of the roving bobbin B₁. Thus, the roving bobbin B₁ having a residual roving is rotatably supported by the lower supportingdevice 103 and therollers cutter device 160 is provided aside the roving bobbin B₁ to be stopped in thebackup device 100. Thecutter device 160 includes acutter rail 162 pivotably supported to apin 163 and adapted to be pivoted by acylinder 165, a verticallymovable support 161 mounted on thecutter rail 162 and adapted to be moved vertically by acylinder 164, and acutter blade 166 mounted on the verticallymovable support 161 for cutting the residual roving on the roving bobbin B₁. - In operation, the
cutter blade 166 is advanced to a position near the outer surface of the roving bobbin B₁, and the verticallymovable support 161 is raised or lowered in a longitudinal direction of the roving bobbin B₁ to thereby cut the residual roving wound on the roving bobbin B₁ in the longitudinal direction. Furthermore, arotary flock roller 142 pivotably supported to arotational shaft 141 is brought into contact with the roving bobbin B₁ to peel off the residual roving from the outer circumferential surface of the roving bobbin. The residual raving after peeled off is fed through asuction duct 145 to a collecting device (not shown).Reference numeral 144 designates a driving motor for rotating theflock roller 142. - Referring to Fig. 7 which is a perspective view of another preferred embodiment 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 the residualroving 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 a fixedframe 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. 7, so as to replace the roving bobbin B₁ having a residual roving as released from the bobbin hanger BH with a blank bobbin B₂.
