Definitions

  • the present invention relates to an automatic winder.
  • a bobbin-tray type automatic winder typically includes plural winding units, a bobbin supplying device, a bobbin transporting device, a yarn-unwound bobbin removing device, and such like.
  • Bobbins around which a spun yarn by a spinning machine is wound (hereinafter, "yarn-wound bobbins") are loaded into a container in bulk, transported to the bobbin supplying device, and introduced into the bobbin supplying device.
  • the bobbin supplying device isolates each bobbin from a pile of the introduced yarn-wound bobbins, and then mounts the isolated yarn-wound bobbins onto trays of the bobbin transporting device.
  • the bobbin transporting device transports the yarn-wound bobbins to each of the winding units. Each winding unit unwinds the yarn from the yarn-wound bobbin that is mounted onto the tray to form a package.
  • the bobbins from which the yarns have been completely unwound by the winding units (hereinafter, "yarn-unwound bobbins") are discharged from the winding units by being transported on the trays of the bobbin transporting device.
  • the yarn-unwound bobbin removing device removes the yarn-unwound bobbins from the trays of the bobbin transporting device.
  • a fresh pile of yarn-wound bobbins are loaded by the bobbin supplying device on downstream-side ones of the trays, from which the yarn-unwound bobbins have been removed.
  • the yarn-unwound bobbins removed by the yarn-unwound bobbin removing device are discharged into a collection box through a yarn-unwound-bobbin chute.
  • the collection box is arranged at a location that is different from where the bobbin supplying device is located, for example, on the floor. Because space needs to be procured at the location separately from where the bobbin supplying device is located to arrange the collection box, the automatic winder has a disadvantage from space-saving perspective.
  • the operation of removing the yarn-unwound bobbins from the collection box that is arranged at the location different from where the bobbin supplying device is located also has to be performed away from where the bobbin supplying device is located.
  • the acts of supplying the yarn-wound bobbins from the pile to the bobbin supplying device and removing the yarn-unwound bobbins from the collection box at different locations increases a movement distance of an operator.
  • the orientations of the taper-shaped bobbin tubes are uniform with respect to the large-diameter end and small-diameter end of the bobbin tubes in an axial direction thereof (bobbin tube large/small-end orientation).
  • the yarn-unwound bobbins after having passed through the yarn-unwound-bobbin chute, are introduced haphazardly into the collection box, leading to disarray with random bobbin tube large/small-end orientations.
  • the bobbin tube large/small-end orientations of the yarn-unwound bobbins need to be made uniform again. If the bobbin tubes large/small-end orientations of the yarn-unwound bobbins are not uniform, a bobbin aligning task needs to be performed to make the bobbin tube large/small-end orientations of the yarn-unwound bobbins uniform before returning the yarn-unwound bobbins to the spinning machine. In the conventional apparatus, this troublesome bobbin aligning task is performed manually by the operator.
  • Japanese Patent Application Laid-open No. H3-111383 proposes a bobbin box 52 that accommodates discharged yarn-unwound bobbins with uniform bobbin tube large/small-end orientation thereof.
  • a receiving member 54 is also required apart from the bobbin box 52.
  • the bobbin box 52 needs to be divided into compartments by using dividing panels 55, and therefore a conveyor 51 is required for performing pitch feeding of the bobbin box 52.
  • the bobbin box 52 is arranged in a yarn-unwound bobbin processing apparatus, and no bobbin supplying device is cited.
  • the present invention has been made in view of the problems described above.
  • One object of the present invention is to realize a compact automatic winder to achieve space-saving.
  • Another object of the present invention is to shorten the distance for which the operator has to move for performing the tasks by bringing the locations where the tasks of supplying the yarn-wound bobbins from the pile to the bobbin supplying device and removing the yarn-unwound bobbins from the collection box close to each other.
  • Still another object of the present invention is to render unnecessary the bobbin aligning task to make the bobbin tube large/small-end orientations of all the yarn-unwound bobbins uniform.
  • an automatic winder includes a bobbin transporting device, a bobbin supplying device, a winding unit, a bobbin removing device, and a collection box.
  • the bobbin transporting device transports a plurality of trays.
  • the winding unit unwinds yarns from the yarn-wound bobbins mounted on the trays being transported by the bobbin transporting device to form a package.
  • the bobbin supplying device supplies yarn-wound bobbins to empty trays that are being transported by the bobbin transporting device so that the bobbin transporting device transports yarn-wound bobbin mounted trays to the winding unit.
  • the bobbin removing device removes yarn-unwound bobbins, which have become empty due to unwinding of yarn by the winding unit, from the trays that are being transported by the bobbin transporting device.
  • the bobbin supplying device includes a box mounting member on which the collection box is mounted.
  • the automatic winder 100 is, for example, a bobbin-tray type automatic winder.
  • the automatic winder 100 mainly includes plural winding units 10, a bobbin transporting device 11, a bobbin supplying device 12, a bobbin removing device 13, and a collection box 40.
  • Yarn-wound bobbins YB around which a spun yarn by a spinning machine (not shown) has been wound are loaded in bulk into a container 8 and transported to the bobbin supplying device 12, and then introduced into the bobbin supplying device 12.
  • the bobbin supplying device 12 isolates each from the pile of yarn-wound bobbins YB, and then mounts one yarn-wound bobbin YB onto a tray 22 of the bobbin transporting device 11.
  • the bobbin transporting device 11 transports the yarn-wound bobbins YB to each of the winding units 10.
  • Each winding unit 10 unwinds the yarn from the yarn-wound bobbin YB mounted onto the tray 22 to form a package.
  • An yarn-unwound bobbin B from which the yarn has been completely unwound by the winding unit 10 is discharged from the winding unit 10 by being transported on the trays 22 of the bobbin transporting device 11.
  • the bobbin removing device 13 picks up the yarn-unwound bobbins B from the trays 22 of the bobbin transporting device 11 to collect the picked-up yarn-unwound bobbins B.
  • a new yarn-wound bobbin YB is loaded onto the now free tray 22 by the bobbin supplying device 12 on a downstream side.
  • Bobbins that have very short residual yarn wound thereon are also discharged from the winding units 10 and collected by the bobbin removing device 13.
  • the yarn-unwound bobbins B include not only completely yarn-unwound bobbins but also those short residual-yarn-wound bobbins.
  • Each of the winding units 10 arranged side by side unwinds the yarn that has been wound on the yarn-wound bobbin YB mounted onto the tray 22, and winds the yarn back on a winding bobbin to form a package.
  • the bobbin transporting device 11 automatically supplies the yarn-wound bobbin YB to each of the winding units 10 and collects the yarn-unwound bobbin B from each of the winding units 10.
  • the bobbin transporting device 11 includes a bobbin transport path 21 and a plurality of the trays 22.
  • the trays 22 are transported over the bobbin transport path 21 by a conveyor, or such like.
  • the yarn-wound bobbin YB or the yarn-unwound bobbin B is mounted onto each of the numerous trays 22 transported over the bobbin transport path 21.
  • the bobbin supplying device 12 supplies the yarn-wound bobbin YB to, from among the trays 22 being transported, a tray 22 with no yarn-wound bobbin YB thereon.
  • the bobbin supplying device 12 includes a bobbin introduction section 23, an isolating section 24, a tray placement section 25, and a bobbin moving section 26.
  • the bobbin introduction section 23 is a section where the pile of yarn-wound bobbins YB transported in the container 8 is introduced.
  • the isolating section 24 isolates the yarn-wound bobbins YB from the pile introduced into the bobbin introduction section 23 while elevating them.
  • the isolating section 24 includes an endless belt 27, and a plurality of bobbin bearing members 28.
  • the endless belt 27 is arranged in a vertical direction and forms a conveyor.
  • the bobbin bearing members 28 are attached to the endless belt 27.
  • the bobbin bearing member 28 has a surface to load the yarn-wound bobbin YB thereon. Only one yarn-wound bobbin YB can be loaded on this surface. Once transported to the bottom of the isolating section 24, the yarn-wound bobbins YB are loaded one on each bobbin bearing member 28 by the circular driving of the endless belt 27, and transported upward. In this manner, the yarn-wound bobbins YB are picked up one by one from the bobbin introduction section 23 and isolated.
  • the tray placement section 25 receives the yarn-wound bobbin YB transported upward by the isolating section 24, makes a distinction of an unwinding end (small-diameter end of a tapered bobbin tube in an axial direction) of the yarn-wound bobbin YB and a supporting end (large-diameter end of the tapered bobbin tube in the axial direction), rotates the yarn-wound bobbin YB so that the supporting end (large-diameter end of the taper-shaped bobbin tube in the axial direction) faces downward, and mounts the yarn-wound bobbin YB onto the tray 22 of the bobbin transporting device 11.
  • a tray 22 is waiting below the tray placement section 25 to receive the yarn-wound bobbin YB.
  • Such tray placement sections are known in the art; for example, one is disclosed in Japanese Patent Application Laid-open No. H8-169525 .
  • the bobbin moving section 26 is arranged between the bobbin introduction section 23 and the isolating section 24.
  • the bobbin moving section 26 moves the pile of yarn-wound bobbins YB from the bobbin introduction section 23 to the isolating section 24.
  • the bobbin moving section 26 includes a swinging and transporting section 29.
  • the swinging and transporting section 29 swings to transport to the isolating section 24 a predetermined quantity of yarn-wound bobbins YB from among the pile of yarn-wound bobbins YB introduced into the bobbin introduction section 23.
  • the swinging and transporting section 29 is driven to swing between a position at which it tilts towards the isolating section 24 (the state shown in FIG. 2 ) or a position at which it tilts in the opposite direction, that is, towards the bobbin introduction section 23.
  • the swinging and transporting section 29 holds the yarn-wound bobbins YB in the bobbin introduction section 23 back from rushing toward the isolating section 24.
  • the swinging and transporting section 29 first swings to the position at which it is tilted towards the bobbin introduction section 23. Consequently, the yarn-wound bobbins YB that have been held back are loaded on the top surface of the swinging and transporting section 29. Thereafter, the swinging and transporting section 29 is caused to swing again and tilt towards the isolating section 24.
  • the swinging and transporting section 29 swings with a certain quantity of the yarn-wound bobbins YB mounted thereon, only the yarn-wound bobbins YB loaded on the swinging and transporting section 29 are introduced into the isolating section 24. Consequently, by the swinging of the swinging and transporting section 29, only a predetermined quantity of the yarn-wound bobbins YB can be transported from among the pile of yarn-wound bobbins YB in the bobbin introduction section 23 to the isolating section 24.
  • the bobbin removing device 13 removes the yarn-unwound bobbins B from the trays 22 on which the yarn-unwound bobbins B discharged from the winding unit 10 are loaded from among the trays 22 that are transported by the bobbin transporting device 11.
  • the bobbin removing device 13 includes a frame 31, a belt member 32, a removing lever 33, a residual-yarn-wound bobbin chute 35, a yarn-unwound-bobbin chute 36, and a residual yarn detection sensor (not shown). Bobbins with a very small amount of yarn left thereon (residual-yarn-wound bobbins) are mixed among the yarn-unwound bobbins B discharged from the winding units 10.
  • the frame 31 forms the base of the bobbin removing device 13.
  • the belt member 32 transports the yarn-unwound bobbins B.
  • the belt member 32 is an endless belt arranged in the vertical direction.
  • the removing lever 33 is an arm that is swingably attached to the frame 31.
  • a picking pulley 34 is arranged on the free end of the removing lever 33.
  • the removing lever 33 moves the yarn-unwound bobbin B towards the belt member 32 with the picking pulley 34 brought in contact with the yarn-unwound bobbin B mounted on the tray 22 in the bobbin transport path 21, pulls up the yarn-unwound bobbin B from the tray 22, and sends the yarn-unwound bobbin B to the belt member 32.
  • the residual yarn detection sensor detects the residual-yarn-wound bobbin from among the yarn-unwound bobbins B that are transported upward along the belt member 32.
  • the residual yarn detection sensor is arranged at a point along the transport path of the belt member 32.
  • the residual-yarn-wound bobbin chute 35 and the yarn-unwound-bobbin chute 36 are arranged above the transport path of the belt member 32 for the yarn-unwound bobbins B.
  • the residual-yarn-wound bobbin chute 35 has a tilt, which causes the yarn-unwound bobbins B with residual yarn thereon to slide and be introduced into a collection box (not shown) for yarn-unwound bobbins B with residual yarn thereon.
  • the yarn-unwound bobbins B with no residual yarn are discharged through the yarn-unwound-bobbin chute 36.
  • the yarn-unwound-bobbin chute 36 also has a tilt, which causes the yarn-unwound bobbins B with no residual yarn to slide and be introduced into the collection box 40.
  • the bobbin removing device 13 removes the yarn-unwound bobbin B from the tray 22 with the unwinding end (top side) thereof on top. Consequently, the yarn-unwound bobbin B with no residual yarn is introduced through the yarn-unwound-bobbin chute 36 into the collection box 40 in the same orientation with its unwinding end (top side) first.
  • the yarn-unwound-bobbin chute 36 extends from the bobbin removing device 13 towards the collection box 40.
  • two collection boxes 40 are arranged. Consequently, the fore-end of the yarn-unwound-bobbin chute 36 is wide enough to allow the yarn-unwound bobbins B to be introduced into both the collection boxes 40.
  • a separator 37 is arranged near the fore-end of the yarn-unwound-bobbin chute 36.
  • the separator 37 switches guidance directions of the yarn-unwound bobbin B, thereby switching the collection box 40 to serve as an introduction destination of the yarn-unwound bobbin B between the two collection boxes 40.
  • a driving source 38 (shown in Fig. 7A , 8A and 9A ) drives the separator 37 to perform this switching action.
  • the collection boxes 40 are arranged side by side on a box mounting member 43 that is arranged on top of the bobbin moving section 26.
  • the box mounting member 43 is a member on which the collection boxes 40 are mounted.
  • the box mounting member 43 is arranged above and across the swinging and transporting section 29 of the bobbin moving section 26.
  • a structure of the collection box 40 is explained in detail below with reference to FIGS. 4 to 10 .
  • two collection boxes 40 are arranged side by side.
  • one collection box 40 will be referred to as a first collection box 41
  • the other collection box 40 will be referred to as a second collection box 42.
  • the first collection box 41 and the second collection box 42 are symmetrical. The following explanation is mainly of the first collection box 41.
  • the side where the yarn-unwound bobbin B is introduced through the yarn-unwound-bobbin chute 36 will be referred to, for the sake of convenience, as a yarn-unwound bobbin introduction side of the collection box 40.
  • the first collection box 41 includes a box body 51, a cover 61, a receptacle 81, and a supporting unit 91.
  • the box body 51 houses the yarn-unwound bobbins B.
  • the box body 51 has an open top.
  • the side walls of the box body 51 are substantially rectangular in shape in a horizontal cross-section.
  • the box body 51 includes a removal assisting member 52 and a detecting section 53.
  • a pair of opposing first side walls 54 forms the side walls of the short side of the box body 51.
  • a pair of opposing second side walls 55 forms the side walls of the long side.
  • the width of the first side walls 54 (length of the short side) is set shorter than the length of the yarn-unwound bobbin B.
  • the width of the second side walls 55 (length of the long side) is set longer than the length of the yarn-unwound bobbin B.

  • the first inner wall panel 56 forms a housing 57 between itself and the first side wall 54 on the yarn-unwound bobbin introduction side for housing the yarn-unwound bobbins B.
  • the first inner wall panel 56 is arranged on the side opposite to the yarn-unwound bobbin introduction side.
  • the position of the first inner wall panel 56 is set such that the length of the long side of the housing 57 is the same as the length of the yarn-unwound bobbin B or slightly longer.
  • the removal assisting member 52 facilitates the operator to put his hands in and lift up the yarn-unwound bobbins B from the first collection box 41.
  • the removal assisting member 52 is provided on the second side wall 55, which is the long-side side wall of the box body 51.
  • the removal assisting member 52 is a notch with an open top and a width that is shorter than the length of the yarn-unwound bobbin B. Because the removal assisting member 52 is provided on the second side wall 55, the operator can grab the pile of yarn-unwound bobbins B by inserting his hands from the side of the pile.
  • the detecting section 53 detects a position of the top surface of each yarn-unwound bobbin B housed in the housing 57.
  • a photoelectric sensor which includes a light emitting element and a light receiving element, is used as the detecting section 53.

  • the width of the first lateral regulating panel 64 is substantially the same as the width of the first side wall 54 of the box body 51.
  • the second lateral regulating panels 65 prevent the yarn-unwound bobbins B being introduced from bouncing off.
  • the second lateral regulating panels 65 are the side walls on the long side of the cover body 63, and the width thereof (length of the long side) is set shorter than the width of the second side wall 55 (length of the long side) of the box body 51. This is so set in the present embodiment to prevent an interference between the yarn-unwound bobbins B being introduced and the second lateral regulating panel 65 when the yarn-unwound bobbins B are introduced into the first collection box 41 through the yarn-unwound-bobbin chute 36 in a slightly oblique direction with respect to the first collection box 41 (refer to FIG. 7B ).
  • the top panel 66 is the upper portion of the cover body 63.
  • the top panel 66 extends across the upper portions of the first lateral regulating panel 64 and the second lateral regulating panels 65.
  • the opening 67 is formed above the housing 57, through which the yarn-unwound bobbins B are introduced.

  • the above-explained automatic winder 100 according to the present embodiment has the following advantages.
  • the bobbin supplying device 12 includes the box mounting member 43 for mounting the collection boxes 40. Therefore, there is no need to procure space for mounting the collection boxes 40 separately from where the bobbin supplying device 12 is located. Consequently, a compact automatic winder 100 can be realized leading to space-saving. Furthermore, the tasks of supplying the yarn-wound bobbins YB from the pile to the bobbin supplying device 12 and removing the yarn-unwound bobbins B from the collection boxes 40 is performed at locations that are not far apart from each other. Consequently, the distance, which the operator has to move to perform these tasks is shortened.
  • the box mounting member 43 is arranged stacked above a portion of the bobbin supplying device 12. Therefore, space is efficiently utilized in a height direction (vertical direction), and space is saved in a width direction (horizontal direction) of the automatic winder 100.
  • the box mounting member 43 is arranged on top of the bobbin moving section 26 that seldom needs to be reached from above. Consequently, space is efficiently utilized in the height direction (vertical direction), and space is saved in the width direction (horizontal direction) of the automatic winder 100.
  • the box mounting member 43 is arranged above the swinging and transporting section 29 of the bobbin moving section 26.
  • the swinging and transporting section 29 transports the yarn-wound bobbin YB by swinging and therefore causes no major vibrations or jolts. Consequently, even if the collection box 40 is arranged on the bobbin moving section 26, the collection box 40 is unaffected by the bobbin moving section 26. Furthermore, the swinging and transporting section 29 transports only a predetermined quantity of the yarn-wound bobbins YB. Consequently, the yarn-wound bobbins YB do not spill over and adversely affect the box mounting member 43 and the collection boxes 40.
  • the isolating section 24 isolates each bobbin from the pile of the yarn-wound bobbins YB while elevating them. Thus, space is saved in the bobbin supplying device 12 in the horizontal direction, and thereby, overall space-saving can be achieved.
  • the bobbin removing device 13 adopts a mechanism by which the yarn-unwound bobbins B are pulled upward, caused to slide down the tilted yarn-unwound-bobbin chute 36, and introduced into the collection box 40 with uniform bobbin tube large/small-end orientation.
  • the collection box 40 is arranged between the opening 67 and the housing 57, and includes the regulating member 71 that maintains a uniform bobbin tube large/small-end orientation of the yarn-unwound bobbins B being introduced into the opening 67 and guides the yarn-unwound bobbins B into the housing 57. Consequently, the uniform bobbin tube large/small-end orientation at the time of introduction of the yarn-unwound bobbins B is not disturbed. Therefore, the task of aligning the yarn-unwound bobbins B in the bobbin tube large/small-end orientation, which is required in the conventional technologies before returning the yarn-unwound bobbins B to the spinning machine, is no longer necessary
  • the regulating member 71 maintains a uniform bobbin tube large/small-end orientation of the yarn-unwound bobbins B by passing the yarn-unwound bobbins B through the passage opening 77 that has a short side that is shorter than the length of the yarn-unwound bobbin B and a long side that is longer than the length of the yarn-unwound bobbin B. Consequently, the yarn-unwound bobbins B being introduced into the opening 67 are guided into the housing 57 while reliably maintaining a uniform bobbin tube large/small-end orientation thereof.
  • the collection box 40 is oriented so that the long side of the passage opening 77 is oriented along the introduction direction of the yarn-unwound bobbins B. Consequently, the yarn-unwound bobbins B being introduced with uniform bobbin tube large/small-end orientation easily pass through the passage opening 77 without changing their orientation, and are swiftly housed in the collection box 40.
  • the cover 61 includes the opening 67 and the regulating member 71.
  • the regulating member 71 forms the passage opening 77 between itself and the inner wall of the cover 61, and includes the slanting panel 74 that guides the introduced yarn-unwound bobbins B into the passage opening 77. Consequently, by opening the cover 61, the regulating member 71 can also be moved, thereby making it easy for the operator to remove the yarn-unwound bobbins B housed in the housing 57 of the box body 51.
  • the housing 57 has the removal assisting member 52, which is a notch with an open top and a width that is shorter than the length of the yarn-unwound bobbin B. This allows the operator, when removing the yarn-unwound bobbins B from the collection box 40, to access the yarn-unwound bobbins B from the side of the housing 57 by inserting his hands in through the removal assisting member 52 and lifting up the yarn-unwound bobbins B. The yarn-unwound bobbins B can be removed more efficiently in this manner than when removing them from above the housing 57. With the cover 61, which includes the blocking member 75 that covers the removal assisting member 52, the yarn-unwound bobbins B are prevented from falling out through the removal assisting member 52 when the cover 61 is closed.
  • the receptacle 81 in which the collected yarn-unwound bobbins B are loaded is lowered when the quantity of the yarn-unwound bobbins B collected therein increases, and raised when the quantity of the yarn-unwound bobbins B collected therein decreases. Consequently, even if the quantity of the yarn-unwound bobbins B collected is small, the dropping height of the yarn-unwound bobbins B being introduced through the opening 67 can be reduced, thereby preventing the yarn-unwound bobbins B from rotating inside the collection box 40 leading to a change in the bobbin tube large/small-end orientation.
  • the operator can still easily remove the yarn-unwound bobbins B because the receptacle 81 is raised as the quantity of the yarn-unwound bobbins B in the receptacle 81 decreases.
  • the collection box 40 includes the detecting section 53 that detects whether a predetermined quantity of the yarn-unwound bobbins B has been collected.
  • the alarm section functions upon receiving the detection signal from the detecting section 53. Consequently, the operator comes to know that a predetermined quantity of the yarn-unwound bobbins B has been collected in the collection box 40, and therefore can remove the yarn-unwound bobbins B from the collection box 40 at an appropriate time.
  • the separator 37 of the yarn-unwound-bobbin chute 36 switches the introduction destination of the yarn-unwound bobbins B among a plurality of the collection boxes 40 arranged side by side. Consequently, the yarn-unwound bobbins B are collected in a plurality of the collection boxes 40. Moreover, the yarn-unwound bobbins B can be removed from the collection box 40 in which a predetermined quantity of the yarn-unwound bobbins B has been collected even while the yarn-unwound bobbins B are being collected in another collection box 40. Consequently, the collection of the yarn-unwound bobbins B can be carried out without interruption.
  • a spring is used as the urging member 94 in the supporting unit 91.
  • an actuator such as an air cylinder, can be used.
  • the actuator can be driven based on, for example, the detection signal of the detecting section 53, to lower the receptacle 81 as the quantity of the yarn-unwound bobbins B increases, and raise the receptacle 81 as the quantity of the yarn-unwound bobbins B decreases.
  • the position of the receptacle 81 can be more accurately controlled with the actuator than with the spring.
