Definitions

  • the present invention relates to a textile machine equipped with a work carrier capable of travelling with respect to plural winding units.
  • Textile machines are known in the art. Such textile machines include plural winding units arranged side-by-side and a work carrier capable of travelling to a desired one of the winding units.
  • the work carrier performs various operations (for example, a yarn joining operation, a bobbin setting operation, a doffing operation and the like) with respect to the winding units.
  • Patent Document 1 discloses an example of such a textile machine.
  • the spinning machine disclosed in Patent Document 1 includes multiple spinning units arranged side-by-side, a yarn joining carrier, and a blower box.
  • the yarn joining carrier is capable of travelling in a direction in which the spinning units are arranged. When yarn breakage occurs in a certain spinning unit, the yarn joining carrier travels to a position of that spinning unit and performs the yarn joining operation in that spinning unit.
  • a suction duct which is connected to the blower box, is arranged on a back side of the spinning machine.
  • the suction duct is arranged parallel to a rail on which the yarn joining carrier travels and supplies suction air current to the yarn joining carrier.
  • One approach to address this issue could be to prepare a space for maintenance on one or both sides of the rail and move the yarn joining carrier into this space thereby causing the back side and the like of the yarn joining carrier to be exposed.
  • the maintenance work can be performed efficiently.
  • a textile machine includes a first winding-unit group that includes at least one winding unit; a second winding-unit group that includes at least one winding unit, wherein a direction of arrangement of the winding unit in the first winding-unit group is same as a direction of arrangement of the winding unit in the second winding-unit group; at least one work carrier; and a first space arranged between the first winding-unit group and the second winding-unit group that can be used when performing maintenance of the work carrier.
  • upstream and downstream respectively mean, in a configuration in which a spinning unit 1 included in the spinning machine 100 spins a sliver 11 and winds a spun yarn 13, upstream and downstream with respect to a running direction of the sliver 11 and the spun yarn 13.
  • the spinning machine (textile machine) 100 shown in FIG. 1 includes a first spinning-unit group (first winding-unit group) 10 including plural spinning units (winding units) 1 arranged side-by-side, a second spinning-unit group (second winding-unit group) 20 including plural spinning units 1 arranged side-by-side, and a yarn joining carrier (work carrier) 30 that joins ends of the spun yarn 13 when the spun yarn 13 becomes discontinuous in any of the spinning units 1 because of yarn breakage or the like.
  • a motor box 40 is arranged on one side and a blower box 50 is arranged on other side of the spinning machine 100.
  • a not-shown driving source that is common with plural spinning units 1 is arranged inside the motor box 40.
  • a blower (air source) 51 is arranged inside the blower box 50.
  • a front side of the spinning machine 100 is the side on which an operator route is arranged. An operator can access a desired spinning unit 1 while being in the operator route.
  • a back side of the spinning machine 100 is the side that is on the other side of the side on which the operator route is arranged.
  • Each spinning unit 1 includes, as shown in FIG. 2 , a sliver supplying section 2, a yarn supplying section 3, a yarn quality monitoring device 7, a yarn pooling device 8, and a winding device 9 in this order from upstream to downstream.
  • a container such as a can, in which the sliver 11 is stored, is arranged.
  • the yarn supplying section 3 forms the spun yarn 13 by spinning the sliver 11 supplied from the sliver supplying section 2, and supplies the spun yarn 13 to the winding device 9.
  • the yarn supplying section 3 included in the spinning unit 1 according to the present embodiment includes a drafting device 4, a spinning device 5, and a delivery roller 6 and a nip roller 61.
  • the drafting device 4 includes four drafting rollers and an opposing roller opposing each drafting roller.
  • the four drafting rollers are a back roller 41, a third roller 42, a middle roller 44 over which a rubber apron belt 43 is stretched, and a front roller 45 in this order from the upstream side.
  • Each drafting roller is rotationally driven at a predetermined speed.
  • the drafting device 4 nips and stretches (drafts) the sliver 11, which is supplied from the sliver supplying section 2 via a sliver guide 21, between the drafting rollers and the opposing rollers, so that the sliver 11 attains a predetermined thickness thereby forming a fiber bundle 12.
  • Twists are applied to the fiber bundle 12, which is formed by the drafting device 4, by the spinning device 5 arranged immediately downstream of the front roller 45.
  • the spun yarn 13 is formed.
  • a device that uses a swirling air current to apply the twists to the fiber bundle 12 is employed as the spinning device 5.
  • the delivery roller 6 and the nip roller 61 are arranged downstream of the spinning device 5. By rotating the delivery roller 6 and the nip roller 61 in a state in which the spun yarn 13, which is formed by the spinning device 5, is nipped between the delivery roller 6 and the nip roller 61, the spun yarn 13 can be conveyed to the downstream side.
  • the spun yarn 13 is supplied to the winding device 9.
  • the delivery roller 6 and the nip roller 61 can be omitted, and instead, the spun yarn 13 can be pulled from the spinning device 5 with the later-explained yarn pooling device 8.
  • the yarn quality monitoring device 7 arranged downstream of the yarn supplying section 3 monitors a state (thickness and the like) of the running spun yarn 13 by using a light transmission sensor to detect a yarn defect (thin yarn, thick yarn, contamination of foreign matter, and the like) in the spun yarn 13.
  • the yarn quality monitoring device 7 can be configured with an electrostatic capacitance sensor, for example.
  • the spun yarn 13 can be cut by using a cutter.
  • the yarn pooling device 8 includes a yarn pooling roller 81, an electric motor 82, and a yarn hooking member 83.
  • the yarn pooling roller 81 is rotationally driven by the electric motor 82.
  • the yarn pooling roller 81 rotates, the spun yarn 13 is wound on a circumferential surface thereof and temporarily pooled.
  • the yarn pooling device 8 is arranged between the winding device 9 and the yarn supplying section 3 and functions as a kind of a buffer.
  • the winding device 9 winds the spun yarn 13 around a bobbin 92 while traversing the spun yarn 13 thereby forming a package 91.
  • the winding device 9 includes a cradle arm 93 and a winding drum 94.
  • the cradle arm 93 includes a supporting section 95 capable of rotatably supporting the bobbin 92 or the package 91.
  • a supporting section 95 capable of rotatably supporting the bobbin 92 or the package 91.
  • the circumferential surface of the bobbin 92 or the package 91 can be brought in contact with the circumferential surface of the winding drum 94.
  • the winding drum 94 is rotationally driven in a state in which the bobbin 92 or the package 91 is in contact therewith, the bobbin 92 or the package 91 is rotated following the rotation of the winding drum 94.
  • the spun yarn 13 is wound around the bobbin 92 or the package 91.
  • a not shown traversing groove is formed on the circumferential surface of the winding drum 94.
  • the spun yarn 13 that is wound around the bobbin 92 or the package 91 is traversed within a predetermined width by this traversing groove.
  • the yarn joining carrier 30 includes a yarn joining device 35 that performs yarn joining.
  • the yarn joining carrier 30 is configured such that it can travel (move) to a desired one of the plural spinning units 1.
  • the yarn joining device 35 is a splicer device that can apply twists to yarn ends by using a swirling air current thereby forming a joint.
  • the yarn joining carrier 30 includes guiding members that, when the spun yarn 13 becomes discontinuous in the spinning unit 1, catch the yarn ends and guide the caught yarn ends to the yarn joining device 35.
  • the yarn joining carrier 30 travels to the spinning unit 1 in which the yarn discontinuation has happened, and catches the yarn ends in that spinning unit 1 and joins the yarn ends.
  • the spun yarn 13 becomes continuous a winding operation in that spinning unit 1 is resumed.
  • the spinning machine 100 includes three yarn joining carriers 30.
  • the spinning machine 100 is configured such that the yarn joining operation in the plural spinning units 1 included in each of the first spinning-unit group 10 and the second spinning-unit group 20 is shared among the three yarn joining carriers 30.
  • a rail 34 is arranged on an upper front side of the spinning machine 100 according to the present embodiment. Accordingly, the yarn joining carriers 30 can be caused to travel on the rail 34 and positioned in front of a desired spinning unit 1 among the plural spinning units 1.
  • a yarn path of the spun yarn 13 is arranged on the front side of each spinning unit 1. Accordingly, the yarn joining carriers 30 are arranged on the side of the spinning units 1 that faces the yarn path but on an outer side of the spinning units 1.
  • the blower 51 that generates suction air current and the like required by the spinning units 1 to perform the winding operation is arranged inside the blower box 50.
  • Each spinning unit 1 is connected to the blower 51 by a pipe 52 arranged on the back side of the spinning machine 100.
  • the pipe 52 is configured as a duct that is arranged parallel to the arrangement direction of the plural spinning units 1. Fiber waste and the like generated in each spinning unit 1 are transported inside the pipe 52 by the action of the suction air current and collected in a not shown collecting section included in the blower box 50.
  • the sliver supplying section 2 is arranged on the front side (that is, toward the yarn path that is the running route of the spun yarn 13 in the spinning units 1) but on a lower side. Accordingly, because the space inside the spinning machine 100 is also narrow, it is difficult to arrange the yarn joining carriers 30 on the front-lower side of the spinning machine 100. Consequently, the yarn joining carriers 30 are arranged so as to travel on a front-upper side.
  • the important parts (yarn joining device 35 and the like) of the yarn joining carrier 30 are arranged on a side closer to the yarn path. That is, the yarn joining device 35 and the like are arranged on a side far from the front side of the yarn joining carrier 30. Moreover, because the front side of the yarn joining carrier 30 is covered with a cover, it is difficult for the operator to access the yarn joining device 35 and the like from the front side of the yarn joining carrier 30. Moreover, to make the surface area required to install the spinning machine 100 compact, the yarn joining carrier 30 is arranged at a position close to the spinning units 1. Accordingly, it is practically impossible for the operator to enter into a space between the spinning unit 1 and the yarn joining carrier 30 and perform maintenance.
  • the plural spinning units 1 are divided into the first spinning-unit group 10 and the second spinning-unit group 20.
  • Each of the first spinning-unit group 10 and the second spinning-unit group 20 includes plural spinning units.
  • a first space for carrier (first space) 31 is arranged between the first spinning-unit group 10 and the second spinning-unit group 20. That is, in the spinning machine 100, the first space for carrier 31 is provided in a mid-portion of the plural spinning units 1 that are arranged side-by-side.
  • the operator can easily perform the maintenance of the yarn joining device 35 and the like by moving the yarn joining carrier 30 to the first space for carrier 31.
  • Similar spaces for maintenance are also arranged, other than the first space for carrier 31, in the spinning machine 100 according to the present embodiment.
  • a second space for carrier (second space) 32 is arranged between the motor box 40 and the first spinning-unit group 10
  • a third space for carrier (third space) 33 is arranged between the blower box 50 and the second spinning-unit group 20.
  • first space for carrier 31 is arranged on one side of the first spinning-unit group 10
  • second space for carrier 32 is arranged on the other side.
  • first space for carrier 31 is arranged on one side of the second spinning-unit group 20
  • third space for carrier 33 is arranged on the other side.
  • the first space for carrier 31 is arranged for a central yarn joining carrier 30a among the three yarn joining carriers 30.
  • the second space for carrier 32 is arranged for a yarn joining carrier 30b that is close to the motor box 40.
  • the third space for carrier 33 is arranged for a yarn joining carrier 30c that is close to the blower box 50.
  • the yarn joining carrier 30c can be accommodated in the first space for carrier 31 while the yarn joining carrier 30a is performing the yarn joining operation in the first spinning-unit group 10
  • the yarn joining carrier 30b can be accommodated in the first space for carrier 31 while the yarn joining carrier 30a is performing the yarn joining operation in the second spinning-unit group 20.
  • the yarn joining carrier 30a can perform the yarn joining operation in both the first spinning-unit group 10 and the second spinning-unit group 20. However, it is allowable to modify the configuration such that the yarn joining carrier 30a can perform the yarn joining operation in only one of the first spinning-unit group 10 and the second spinning-unit group 20.
  • a width 31w of the first space for carrier 31, which is arranged between the first spinning-unit group 10 and the second spinning-unit group 20, is larger than a width 30w of the yarn joining carrier 30.
  • the magnitude of the difference between the width 31w of the first space for carrier 31 and the width 30w of the yarn joining carrier 30 is set such that the operator can enter into the first space for carrier 31 from the operator route that is present on the front side of the spinning machine 100.
  • This difference is, for example, equal to or smaller than the width of one spinning unit 1.
  • the first space for carrier 31 is arranged at a position that roughly equally divides the plural spinning units 1 that are arranged side-by-side.
  • the number of spinning units 1 in the first spinning-unit group 10 is roughly equal to the number of spinning units 1 in the second spinning-unit group 20.
  • a portion of the pipe 52, which supplies the suction air current to each spinning unit 1, is arranged in the first space for carrier 31.
  • the pipe 52 is arranged across the first spinning-unit group 10, the second spinning-unit group 20, and the first space for carrier 31. Because the pipe 52 is not made discontinuous because of the presence of the first space for carrier 31, the route over which the suction air current is supplied from the blower box 50, which is arranged on one side of the spinning machine 100, to each spinning unit 1 can be made simple.
  • the rail 34 that determines the travelling routes of the three yarn joining carriers 30 is arranged across the first spinning-unit group 10, the second spinning-unit group 20, the first space for carrier 31, the second space for carrier 32, and the third space for carrier 33. This arrangement allows the configuration for moving the plural yarn joining carriers 30 among the plural spinning-unit groups 10 and 20 and the spaces for carriers 31 to 33 to be made simple.
  • the spinning machine 100 includes the first spinning-unit group 10, the second spinning-unit group 20, and the three yarn joining carriers 30.
  • Plural spinning units 1 are arranged in the first spinning-unit group 10, and plural spinning units 1 are arranged in the second spinning-unit group 20.
  • the direction of arrangement of the spinning units 1 in the first spinning-unit group 10 is the same as the direction of arrangement of the spinning units 1 in the second spinning-unit group 20.
  • both the front side of the first spinning-unit group 10 and the front side of the second spinning-unit group 20 face toward the same direction with respect to the operator route.
  • the first space for carrier 31 for maintenance of the yarn joining carrier 30 is arranged between the first spinning-unit group 10 and the second spinning-unit group 20.
  • the maintenance of the yarn joining carrier 30 can be suitably performed by accommodating the yarn joining carrier 30 in the first space for carrier 31.
  • the spinning machine 100 that includes three yarn joining carries 30 as in the present embodiment because the maintenance of the central yarn joining carrier 30a can be performed by accommodating it in the first space for carrier 31, the travelling and operation of the yarn joining carriers 30b and 30c arranged on either side are not much affected. As a result, it is possible to suppress the decrease in the efficiency of the entire spinning machine 100 even when the maintenance of the yarn joining carrier 30 is being performed.
  • the width 30w of the yarn joining carrier 30 is smaller than the width 31w of the first space for carrier 31.
  • the width 30w of the yarn joining carrier 30 is smaller than the width 31w of the first space for carrier 31 but larger than a width of the yarn joining device 35.
  • the width 30w of the yarn joining carrier 30 is larger than the width of any of the spinning units 1.
  • the plural spinning units 1 are divided into the first spinning-unit group 10 and the second spinning-unit group 20.

  • a portion of the pipe 52 is arranged in the first space for carrier 31.
  • the blower 51 supplies air to each spinning unit 1.
  • the air to be supplied from the blower 51 to the spinning units 1 passes through the pipe 52.
  • the pipe 52 can be arranged across the first spinning-unit group 10 and the second spinning-unit group 20, and an air-supply route from the blower 51 can be made simple.

  • the rail 34 is arranged across the first spinning-unit group 10, the first space for carrier 31, and the second spinning-unit group 20.
  • the yarn joining carrier 30 is arranged such that the side on which the yarn path, which is the running route of the spun yarn 13, is arranged and an operation side of the yarn joining carrier 30 face each other, and the yarn joining carriers 30 travel with respect to the first spinning-unit group 10 and the second spinning-unit group 20.

  • the important parts of the yarn joining carrier 30 are usually arranged on the side that is close to the spinning units 1. Accordingly, as explained above, it is particularly effective to provide the first space for carrier 31 for the maintenance.
  • three yarn joining carriers 30 are provided.
  • the spinning machine 100 includes the second space for carrier 32 and the third space for carrier 33. While the first space for carrier 31 is arranged on one side of the first spinning-unit group 10, the second space for carrier 32 is arranged on the other side. While the first space for carrier 31 is arranged on one side of the second spinning-unit group 10, the third space for carrier 33 is arranged on the other side.
  • maintenance of the yarn joining carriers 30 can be performed by using the second space for carrier 32 and the third space for carrier 33.
  • the maintenance of the yarn joining carrier 30b located close to the second space for carrier 32 can be performed in the second space for carrier 32, and the maintenance of the yarn joining carrier 30c located close to the third space for carrier 33 can be performed while it is in the third space for carrier 33. Therefore, the travelling and operation of the remaining yarn joining carriers 30 are not much affected even if maintenance is being performed on a certain yarn joining carrier 30.
  • an automatic winder 100x includes a winder unit 1x that unwinds a yarn from a yarn supplying bobbin and winds the unwound yarn around a winding bobbin.
  • plural winder units 1x are arranged side-by-side to form a winder-unit group 60.

  • the yarn quality monitoring device 7 can be arranged at any other place as far as it is arranged downstream of the spinning device 5.
  • the present invention can be applied to, apart from the spinning machine 100 (air spinning machine) shown in the first embodiment, an open-end spinning machine that forms a spun yarn by first separating a fiber bundle, such as a sliver or a thick yarn, into very small fibers or a very small fiber bundle, and then re-bundling the separated very small fibers or the very small fiber bundle while applying twists thereto.
  • a fiber bundle such as a sliver or a thick yarn
  • the application of the present invention is not limited only to spinning machines and automatic winders, however, the present invention can be widely applied to general textile machines that include plural winding units arranged side-by-side and work carriers.
  • a textile machine includes a first winding-unit group, a second winding-unit group, and at least one work carrier.
  • the first winding-unit group includes at least one winding unit.
  • the second winding-unit group includes at least one winding unit.
  • a direction of arrangement of the winding unit in the first winding-unit group is same as a direction of arrangement of the winding unit in the second winding-unit group.
  • a first space is arranged between the first winding-unit group and the second winding-unit group that can be used when performing maintenance of the work carrier.
  • the maintenance of the work carrier can be suitably performed by accommodating the work carrier in the first space. Accordingly, because the maintenance of the work carrier can be performed in between the first winding-unit group and the second winding-unit group, it is not necessary, as in the conventional configuration, to move the work carrier to one of the ends of the textile machine, and therefore the maintenance of the work carrier can be performed efficiently.
  • the width of the work carrier is equal to or smaller than the width of the first space.
  • a winding unit is arranged not in the first space but in the first winding-unit group and the second winding-unit group.
  • the textile machine further includes an air source and a pipe.
  • the air source is for supplying air to each of the winding units.
  • the pipe is for supplying the air from the air source to the winding units.
  • a portion of the pipe is arranged in the first space.
  • the pipe can be arranged across the first winding-unit group and the second winding-unit group, and an air-supply route from the air source can be made simple.
  • the textile machine further includes a rail that movably guides the work carrier. Moreover, it is preferable that the rail is arranged across the first winding-unit group, the first space, and the second winding-unit group.
  • the work carrier is arranged such that the side on which a yarn path, which is a running route of a yarn, is arranged and a operation side of the work carrier face each other, and the work carrier is capable of moving with respect to the first winding-unit group and the second winding-unit group.
  • the winding unit includes a spinning device that forms a spun yarn by spinning a sliver supplied from a sliver supplying section arranged on a lower side in a height direction of the winding unit; and a winding device that winds the spun yarn, which is spun by the spinning device, on an upper side in the height direction of the winding unit and forms a package.
  • the work carrier is generally arranged so as to face an upper part of the winding unit so that the work carrier does not interfere with the sliver supplying section. Therefore, it is highly difficult to secure a space for maintenance of the work carrier in a state in which the work carrier faces the winding unit.
  • important parts of the work carrier are generally arranged on the side that is close to the winding units. Accordingly, as explained above, it is particularly effective to provide the first space for the maintenance.
  • the textile machine includes two or more work carriers.
  • the textile machine further includes at least one of a second space and a third space.
  • the second space is arranged on other side of the first winding-unit group with the first space being arranged on one side of the first winding-unit group
  • the third space is arranged on other side of the second winding-unit group with the first space being arranged on one side of the second winding-unit group.
  • the maintenance of the work carrier can be performed by using the second space or the third space.
  • the maintenance of a work carrier located close to the second space can be performed in the second space
  • the maintenance of a work carrier located close to the third space can be performed in the third space. Therefore, the travelling and operation of the remaining work carriers are not much affected even if maintenance is being performed on a certain work carrier.
  • the above textile machine preferably includes an assisting device that assists the winding units and is arranged in the first space, and a top surface of the assisting device is located at a lower level than a lower surface of the work carrier. With this configuration, the first space can be used effectively.
  • At least one of the winding units is arranged in the first space, and the winding unit arranged in the first space or other plural winding units are removable or movable in a direction away from a travelling route of the work carrier.
