Description

  The present invention relates to a winding device for a knitting machine, which is arranged at a lower part of a knitting machine for producing a tubular knitted fabric and feeds the tubular knitted fabric with a winding tension with a pulling roller interposed therebetween.

  Conventionally, in a knitting machine such as a circular knitting machine or a flat knitting machine that produces a tubular knitted fabric, a tubular knitted fabric produced by a knitting unit provided at the upper part of the knitting machine is arranged at the lower part of the knitting machine. It is known to wind up and store with a winder. In general, this winding device is configured to sandwich the tubular knitted fabric by a plurality of tension rollers provided in a winding path for winding the tubular knitted fabric at an upper portion thereof to add a winding tension and to form the tubular knitted fabric. The outer surface of the roller is sandwiched between rollers and fed from a cylindrical shape to a double flat shape (flat shape), and the fed flat double knitted fabric is wound into a roll shape by a winding roller at the lower part of the winding device. take.

  If the cylindrical knitted fabric produced in the knitting part is sent out to the winding device while being in a cylindrical shape and wound, the tubular knitted fabric is likely to be wrinkled, and it is necessary to remove the wrinkles by subsequent processing. Arise. In order to prevent the occurrence of such wrinkles, usually, as in Patent Document 1, for example, a winding-out mechanism for adjusting the tubular knitted fabric to a predetermined width is provided in the winding path of the tubular knitted fabric, and this apparatus is used. It is known that the tubular knitted fabric is guided so as to be flattened smoothly, and then the tubular knitted fabric is sandwiched by a tension roller and stored in a winding device.

  However, even in the method of Patent Document 1, since the tubular knitted fabric is sandwiched between the flat knitted fabrics by the pulling roller, the flat knitted fabric is bent at 180 degrees or close to both ends and is called a center mark. A crease occurs. Further, when the flat knitted fabric is wound in a roll shape by a winding roller at the lower part of the winding device, the crease becomes deeper. This broken wrinkle is known as a wrinkle that is difficult to remove by subsequent processing. This crease becomes deeper depending on the knitting conditions such as the type of yarn used and the knitting structure, and it may be difficult to remove even if the knitted fabric is processed. For this reason, conventionally, various countermeasures have been proposed for the occurrence of creases in such a winding device.

  For example, as in Patent Document 2, instead of winding a flat knitted fabric in a roll shape with a winding roller at the lower part of the winding device, a swing-down winding that folds and stores a tubular knitted fabric with a moving knitted fabric guide A take-off device has been proposed. As a result, deepening of the wrinkles is reduced, but folding wrinkles due to the pinching of the tubular knitted fabric by the tension roller still occur.

  As a countermeasure against bending wrinkles caused by the pinching by the tension roller, for example, as shown in Patent Document 3, it is possible to break by using an adjustment roller that can reduce the diameter of the tension roller at a portion where both ends of the tubular knitted fabric pass. Methods to prevent wrinkles have been proposed. Further, for example, as in Patent Document 4, one end of a tubular knitted fabric is cut with a cutter to develop the tubular shape, and instead of a flat double flat knitted fabric, a flat flat knitted fabric As an open device system that winds up with a winding roller, for example, as in Patent Document 5, double winding is performed by cutting both ends of a tubular knitted fabric with a cutter and winding it with two winding rollers as two flat knitted fabrics A type of winding device has been proposed.

  However, in Patent Document 3, as shown in FIG. 5A, although the folding wrinkles 65 at both ends of the flat double knitted fabric are reduced to some extent by the adjusting rollers 91 having small diameters at both ends, Depending on the knitting conditions such as the structure and gauge, creases that are still difficult to resolve may occur. In addition, fine adjustment is required to match the position of the adjustment roller 91 with the end of the knitted fabric, which requires extra work time.

  In addition, the open device method of Patent Document 4 and the double winding method of Patent Document 5 are both winding methods for cutting a tubular knitted fabric, although creases that are difficult to resolve are not generated. Since it is wound up as a flat knitted fabric, if a tubular shape is required in the subsequent knitted fabric production process, an extra step of reconnecting the cut portions to return to the tubular shape is required. Furthermore, in the open device system, the winding device becomes large because the width of the knitted fabric for winding is doubled. Also, the double winding method divides the knitted fabric into two, so that a tubular knitted fabric having a double diameter must be produced in order to obtain the required knitted fabric width, and the knitted portion is large. As a result, the entire apparatus becomes large, requiring a large installation space, and the cost is high.

  The present invention solves the above-described problems and is a small and low-cost knitted fabric that can stably feed and store the tubular knitted fabric while preventing wrinkles from being generated on the tubular knitted fabric by the tension roller. An object of the present invention is to provide a winding device for a machine.

  A winding device of a knitting machine according to the present invention includes a plurality of pulling rollers disposed in a lower part of a knitting machine that produces a tubular knitted fabric and provided in a winding path of the tubular knitted fabric. The cylindrical knitted fabric is pressed between the rollers and sent out with the winding tension applied, and the cylindrical knitted fabric is stored and installed inside the cylindrical knitted fabric in the winding path in the radial direction. And a tentering mechanism that adjusts the tubular knitted fabric to a predetermined width along the axial direction of the tension roller, the tension roller being attached to a lower portion of the tentering mechanism, and having a diameter of the tubular knitted fabric. A plurality of inner rollers disposed inward in the axial direction and extending in the axial direction, and a plurality of outer rollers extending in the axial direction and opposed to the respective inner rollers on the radially outer side of the tubular knitted fabric. The knitted fabric is sandwiched between the inner roller and the outer roller from the radially inner side and the radially outer side and pressed. It is intended to feed while holding the cylindrical shape.

  According to this configuration, the tubular knitting is performed by sandwiching the inner surface and the outer surface of the tubular knitted fabric between the inner roller and the outer roller of the tension roller disposed on the radially inner side and the radially outer side of the tubular knitted fabric. Since the ground is fed in a state of being held in a cylindrical shape, the outer surface of the tubular knitted fabric is sandwiched between the rollers and is not fed into a double flat shape (flat shape) like a conventional tension roller. It is possible to prevent the occurrence of creases at both flat ends. At the same time, by pulling the tubular knitted fabric between the inner roller and the outer roller of the pulling roller, a constant winding tension is applied to the tubular knitted fabric, thereby enabling stable feeding.

  In the present invention, it is preferable that one of the inner roller and the outer roller facing each other is a driving roller and the other is a driven roller. By driving the tension roller, the tubular knitted fabric can be automatically fed out with a constant winding tension.

  Preferably, the pulling roller is composed of a plurality of split rollers in which the inner roller is divided into a plurality along the axial direction, and between the split rollers according to the width adjustment of the tubular knitted fabric in the tentering mechanism. Increase or decrease the interval. Therefore, in conjunction with the width adjustment of the tubular knitted fabric in the tentering mechanism, the width of the inner roller can be adjusted accordingly.

  More preferably, the split rollers of the two inner rollers are arranged so as to be staggered in the vertical direction, and the split of the other inner roller is larger than the axial distance between the split rollers of one inner roller. The axial length of the roller is set long. In this case, since the split rollers of both inner rollers are set to overlap at both ends, the tubular knitted fabric can be fed out more stably.

  Preferably, the tension roller is provided with an elastic means for adding an elastic force to the other roller to one of the outer roller and the inner roller. The elastic means is a torsion spring. Therefore, the tubular knitted fabric can be pressed between the inner roller and the outer roller.

  Preferably, the knitted fabric sent out by the pulling roller is a swing-down winding device that swings down and stores the knitted fabric. Therefore, since the tubular knitted fabric is not wound up in a roll shape, it is possible to prevent the folds caused by this from occurring in the tubular knitted fabric.

  Moreover, it is preferable that the said tension | pulling roller comprises one set by the one outer side roller and the two inner side rollers arrange | positioned up and down, and has this two or more sets. In this case, the tubular knitted fabric can be sent out stably.

  Preferably, a plurality of guide rollers which are attached to the tentering mechanism and guide both axial ends of the tubular knitted fabric are provided. The guide roller is provided so as to guide the guide roller to a position below the tension roller. Accordingly, the tension roller extending in the axial direction sandwiching the tubular knitted fabric and the guide rollers at both ends in the axial direction of the tubular knitted fabric can reduce the difference in winding tension between the portion of the tubular knitted fabric hit by the tensile roller and the end portion. Thus, the tubular knitted fabric can be smoothly fed out.

  Preferably, a plurality of joints pivotally supported by a joint shaft are attached to a lower portion of the width raising mechanism, and each split roller of the inner roller is supported by each joint, and the width of the tubular knitted fabric is adjusted. The interval between each joint and between each split roller is increased or decreased. Further, an elastic means is provided between the joints, and the distance between the joints is kept at an equal distance. Further, the elastic means is a coil spring extrapolated to the joint shaft between the joints. Accordingly, the distance between the split rollers can be increased or decreased evenly in conjunction with the width adjustment of the tubular knitted fabric in the tentering mechanism.

  In the present invention, the cylindrical knitted fabric is formed into a cylindrical shape by sandwiching the inner side surface and the outer side surface of the cylindrical knitted fabric between the inner side roller and the outer side roller arranged on the radially inner side and the radially outer side of the cylindrical knitted fabric. Since it is fed out in a state of being held on the outer side of the knitted fabric, the outer surface of the tubular knitted fabric is sandwiched between the rollers so that it is not fed into a double flat shape (flat shape). Can be prevented. At the same time, by pulling the tubular knitted fabric between the inner roller and the outer roller of the pulling roller, it is possible to stably feed while applying a certain winding tension to the tubular knitted fabric.

  In this example, in the tension roller 2, the outer roller 5 is a driving roller, and the first inner roller 3 and the second inner roller 4 are driven rollers. The outer roller 5 is driven by, for example, a servo motor, and a tubular knitted fabric 6 is sandwiched between the outer roller 5 and the first inner roller 3 and the second inner roller 4 so that the outer roller 5 rotates in the direction opposite to the rotation direction of the outer roller 5. 1 A winding tension is applied to the tubular knitted fabric 6 by rotating the inner roller 3 and the second inner roller 4. By driving the tension roller 2, the tubular knitted fabric 6 can be automatically fed out with a constant winding tension.

  Contrary to this example, the first inner roller 3 and the second inner roller 4 may be driving rollers, and the outer roller 5 may be a driven roller, or the first inner roller 3, the second inner roller 4 and the outer roller. Both rollers 5 may be drive rollers and may be rotated at the same peripheral speed. Further, the driving of the tension roller 2 may be a mechanical drive that transmits the mechanical power from a mechanical power instead of an electric drive such as a servo motor.

  The cylindrical knitted fabric 6 produced by the knitting unit at the upper part of the knitting machine in FIG. 1 (A) passes through the winding path P of the winding device 1 and is installed below it via the upper tentering mechanism 10. The first inner roller 3 and the second inner roller 4 and the outer roller 5 are fed and stored downward while holding the cylindrical shape while the inner surface and the outer surface are sandwiched and pulled. .

  Hereinafter, detailed configurations of the tentering mechanism 10 and the tension roller 2 in the winding device 1 will be described with reference to FIGS. FIG. 3 is a front view of the tentering mechanism 10 in the winding device 1 and the first inner roller 3 and the second inner roller 4 attached thereto. FIG. 4 is a plan view of FIG.

  As shown in FIG. 3, for example, the tentering mechanism 10 equivalent to that of Patent Document 1 is used, and two upper and lower racks provided on the support body 50 with the tip portion supported and spaced apart vertically. -It has pinion mechanisms 52 and 53. As shown in the plan view of FIG. 4, the tentering mechanism 10 has two nested rod frames 54 and four fixed frames 55 facing each other, and has a hexagonal shape in plan view. In addition, the rack and pinion mechanisms 52 and 53 have their tips supported by the support body 50 and their bases connected to the connection points of the frames 54 and 55. The tentering mechanism 10 includes the expansion and contraction of the upper rack and pinion mechanism 52 in the oblique direction, the expansion and contraction of the lower rack and pinion mechanism 53 in the axial direction W, and the expansion and contraction of the telescopic rod frame 54 in the axial direction W. As a whole, it expands and contracts in the width direction W as a whole.

  A plurality of guide rollers 51 for guiding both ends of the tubular knitted fabric in the axial direction W are provided in the tentering mechanism 10 of FIG. In this example, a total of four are provided, two at each end. This guide roller 51 is provided so as to guide it below the tension roller 2. The tension roller 2 extending in the axial direction W sandwiching the tubular knitted fabric 6 and the guide rollers 51 at both ends in the axial direction of the tubular knitted fabric 6, and the winding tension of the end portion of the tubular knitted fabric 6 where the tensile roller 2 hits. A difference can be reduced and a cylindrical knitted fabric can be sent out smoothly. The guide roller 51 may have a large diameter or a wide width. In this example, the guide roller 51 is arranged so as to rotate about the axis in the depth direction D. However, like the tentering mechanism 10 and the tension roller 2, the guide roller 51 is arranged to rotate about the axis in the axial direction W. May be.

  The tentering mechanism 10 has a plurality of joints 8 pivotally supported by the joint shaft 7 at the lower part thereof. The joint 8 is attached to the lower part of the support main body 50 at a substantially central position in the axial direction W, and is attached to both ends of the first joint 81 and the lower rack and pinion mechanism 53 that are held so as not to be relatively movable in the axial direction W. The second joints 82 and 82 are arranged on both outer sides in the axial direction W and are movably held in the axial direction W, and are arranged between the first joint 81 and the second joints 82 and 82 in the axial direction W. It consists of third joints 83 and 83 held movably. Coil springs 71 which are elastic means extrapolated to the joint shaft 7 are provided between the joints.

  The tension roller 2 in FIG. 4 has two sets in the depth direction D (vertical direction in FIG. 4) across the X axis, which is the central axis in the depth direction D of the winding device 1, and each set has a vertical direction V (in FIG. 4). A first inner roller 3, a second inner roller 4, and an outer roller 5 arranged in the paper surface direction) are provided. Thereby, the cylindrical knitted fabric 6 can be sent out stably.

  The first inner roller 3 in FIG. 3 is supported by the first joint 81 of the tentering mechanism 10 at the center position in the axial direction W, and can be rotated about the axis but is not relatively movable in the axial direction W. Further, one first stationary split roller 31 is provided. Two first movable end split rollers 32 supported by the second joints 82 and 82 at both end positions in the axial direction W and rotatable about the axis and held movably in the axial direction W, 32 is provided. Further, supported by the third joints 83 and 83 at a position between the first stationary split roller 31 and the first movable end split roller 32 in the axial direction W, and can rotate about the axis and move in the axial direction W. There are provided two first movable split rollers 33 and 33 that are freely held. The first inner roller 3 includes a total of five split rollers 31 to 33.

  The second inner roller 4 is supported by both ends of the first immobile split roller 31 of the first inner roller 3, and can be rotated around the axis and held in a relatively immovable manner in the axial direction W. Non-moving split rollers 41 are provided. Further, two second movable end split rollers 42 supported by one end of the first movable end split roller 32 of the first inner roller 3 and capable of rotating around the axis and being movable in the axial direction W are supported. , 42 are provided. Further, it is supported by one end of the first movable split roller 33 at a position between the second stationary split roller 41 and the second movable end split roller 42, and can rotate around the axis and move in the axial direction W. Two held second movable split rollers 43 and 43 are provided. The second inner roller 4 includes a total of six split rollers 41 to 43.

  There are four coil springs 71 extrapolated to the joint shaft 7, between the first joint 81 and the second joint 82, and between the second joint 82 and the third joint 83. Between the first movable end split roller 32 and the first movable split roller 33 in the first inner roll 3, and between the first movable split roller 33 and the first stationary split roller 31. And the distance between the second movable end split roller 42 and the second movable split roller 43 and the distance between the second movable split roller 43 and the second stationary split roller 41 can be increased or decreased evenly. .

  Each split roller of the first inner roller 3 and the second inner roller 4 expands and contracts in the axial direction W along with the expansion and contraction by adjusting the width of the tubular knitted fabric 6 in the tentering mechanism 10. That is, when the second joint 82 arranged on both outer sides in the axial direction W expands and contracts in the axial direction W, the first movable end split roller 32 of the first inner roller 3 supported thereby is axially moved. The second movable end split roller 42 supported by one end of the first movable end split roller 32 extends and contracts in the axial direction while expanding and contracting to W. When the third joint 83 disposed between the first joint 81 and the second joint 82 expands and contracts in the axial direction W, the first movable split of the first inner roller 3 supported by the third joint 83 is expanded accordingly. The roller 33 expands and contracts in the axial direction W, and the second movable split roller 43 supported by one end of the first movable split roller 33 expands and contracts in the axial direction W.

  As a result, the inner roller 3 of the tension roller 2 is increased or decreased evenly by interlocking with the expansion and contraction of the joint shaft 7 according to the width adjustment of the tubular knitted fabric 6 in the tentering mechanism 10. The length of the four axial directions W can be changed.

  Depending on the width adjustment of the tubular knitted fabric 6 of the tentering mechanism 10, the range between the split rollers increases or decreases, but regardless of the magnitude of the increase or decrease, For example, the axial length of the split roller of the second inner roller 4 is set to be longer than the interval between the split rollers of the first inner roller 3. That is, the overlapping range of the split roller of the first inner roller 3 and the split roller of the second inner roller 4 is set to occur at both ends of all the split rollers. However, the outermost first movable end split roller 32 and the second movable end split roller 42 are set so that the overlapping range occurs only at the inner end. Thereby, it is possible to make the winding tension uniform over the entire tubular knitted fabric 6 in the range where the pulling roller 2 hits.

  In this example, one movable split roller is installed in each inner roller, but two or more movable split rollers can be installed, and the inner roller is not used as a split roller but used as one long roller. It can be used properly according to the application.

  Although not shown in the drawings, the swing-off device is provided below the pulling roller 2 and, for example, a knitted fabric guide provided below the take-up roller that sandwiches the tubular knitted fabric reciprocates while keeping parallel to the take-up roller. Then, the tubular knitted fabric 6 descending from the winding roller is guided and stored so as to be folded into a storage unit provided at the lower part of the winding device 1. Note that the storage unit may be moved instead of moving the knitted fabric guide. With this swing-off device, the tubular knitted fabric is not wound into a roll shape as in the prior art, so that wrinkles generated on the tubular knitted fabric can be reduced.

  As shown in FIG. 5B, the inner rollers 3, 4 such as the split roller 42 of the tension roller 2 disposed on the radially inner side 61a and the radially outer side 61b of the tubular knitted fabric 6, and the outer roller 5, Thus, by sandwiching the inner side surface and the outer side surface of the tubular knitted fabric 6, the tubular knitted fabric 6 can be fed out while being held in a tubular shape.

  As described above, the present invention provides a tubular cylinder by sandwiching the inner surface and the outer surface of the tubular knitted fabric between the inner roller and the outer roller of the tension roller disposed on the radially inner side and the radially outer side of the tubular knitted fabric. Since the cylindrical knitted fabric is fed out while being held in a cylindrical shape, the cylindrical knitted fabric is sandwiched between the rollers from the outside and is not fed into a double flat shape (flat shape) like a conventional tension roller. Occurrence of creases at the flat ends of the knitted fabric can be prevented. At the same time, by pulling the tubular knitted fabric between the inner roller and the outer roller of the pulling roller, a constant winding tension is applied to the tubular knitted fabric, thereby enabling stable feeding.

In this embodiment, the adjustment of the tentering device prevents the occurrence of creases in the tubular knitted fabric, but the adjustment of the tentering device does not require a fine adjustment like a conventional adjusting roller, Since it is possible to easily and quickly set the knitted fabric winding without creases, the efficiency of the work time can be measured.

  In this embodiment, the tentering mechanism 10 uses the mechanism shown in FIGS. 3 and 4, but is not limited to this, and other tentering mechanisms can be used.

  As described above, the preferred embodiments have been described with reference to the drawings. However, those skilled in the art will readily consider various changes and modifications within the obvious scope by looking at the present specification. Accordingly, such changes and modifications are to be construed as within the scope of the invention as defined by the appended claims.
