Description

Melt spinning equipment

Technical Field

The present invention relates to a melt spinning apparatus including a plurality of spinning tractors.

Background

The spinning tractor comprises: a spinning device for spinning silk thread; a drawing device for winding the plurality of threads spun in the spinning device; and a yarn breakage processing device for storing the yarn by operating the yarn breakage processing device after the yarn winding in the traction device is completed. Patent document 1 (japanese patent application laid-open No. 2013-57148) discloses a broken wire processing apparatus comprising: a 1 st cutter for cutting the plurality of threads; a suction device having a suction unit (suction port) for sucking the plurality of wires cut by the 1 st cutter; and a 2 nd cutter for cutting the plurality of threads sucked by the suction unit.

In a spinning tractor, when a plurality of threads spun from a spinning device are to be drawn into the tractor, a worker usually receives the plurality of threads spun from the spinning device by a suction gun and draws the plurality of threads held by the suction gun into the spinning tractor. Here, in general, the number of suction guns is small relative to the number of spinning tractors. Therefore, in a case where yarn hanging occurs at the same timing in a plurality of spinning machines, when yarn hanging is performed in one spinning machine, the yarn spun from the spinning device cannot be received by the suction gun in the other spinning machines.

Therefore, the plurality of filaments spun from the spinning device are temporarily held in the suction section of the filament breakage processing device. As a method for holding a wire in a wire breakage processing apparatus, there are the following methods: the operator receives the plurality of threads spun from the spinning device, cuts the ends of the plurality of threads using a cutting tool (scissors, cutter, etc.), and then attracts and holds the plurality of threads by the attraction unit. However, in this method, since the operator performs the work while holding the cutting tool, operability and safety are not good.

As other methods for holding a wire in a wire breakage processing apparatus, there are the following methods: the plurality of wires are cut by a cutter (a 1 st cutter, a 2 nd cutter) of the wire breakage processing apparatus, and the plurality of wires after cutting are held by suction by the suction unit. However, the cutter of the yarn breakage processing device continuously (gradually) cuts a plurality of yarns one at a time or a plurality of yarns at a time. Therefore, when the yarn is used in such a manner that a plurality of yarns are cut at once in a state of being bundled, a problem such as breakage of the cutter or a shortened lifetime occurs. Therefore, the function of the original cutter may be impaired.

Disclosure of Invention

An object of one aspect of the present invention is to provide a melt spinning apparatus capable of improving operability and safety when a plurality of filaments spun from a spinning device are drawn into a drawing device, and capable of preventing occurrence of a defect in a cutter of a filament breakage processing device, when a plurality of spinning drawing machines are provided.

The melt spinning apparatus according to one aspect of the present invention includes a plurality of spinning tractors each including a spinning device for spinning a plurality of filaments, a drawing device for drawing the plurality of filaments, and a filament breakage processing device for temporarily storing the plurality of filaments, and a cutting unit for cutting the plurality of filaments by an operator, the cutting unit being provided in at least one of the drawing device and the filament breakage processing device, the cutting unit being configured to be capable of cutting a bundle of the plurality of filaments before the filaments are drawn into the drawing device, the filament breakage processing device including: at least one cutter for continuously cutting the plurality of threads one at a time or a plurality of threads at a time along an arrangement direction in which the plurality of threads are arranged; and a suction unit for holding the plurality of wires cut by the cutter and the plurality of wires cut by the cutter.

The melt spinning apparatus according to one aspect of the present invention includes a cutting unit for an operator to cut a plurality of filaments. That is, the melt spinning apparatus includes a dedicated cutting unit for cutting the bundle of the plurality of filaments before the filaments are drawn by the drawing device when the plurality of filaments spun by the spinning device are drawn by the drawing device. Thus, the operator can cut the bundle of the plurality of wires collectively at one time by the cutting unit without using the cutting tool or the cutter. Therefore, when a plurality of spinning tractors are provided, operability and safety can be improved when a plurality of filaments spun from a spinning device are hung on the tractors, and occurrence of a defect in a cutter of a filament breakage processing device can be prevented.

In the melt spinning apparatus, a plurality of filaments cut by the cutting section are held in a suction section of a filament breakage processing device provided in each spinning tractor. Therefore, even when the yarn spun from the spinning device cannot be received by the suction gun, the yarn can be stored in the suction unit.

In one embodiment, the cutting unit may be provided in at least one of the drawing device and the yarn breakage processing device for each of the plurality of spinning tractors. In this configuration, since a plurality of filaments can be cut in the cutting section provided in the drawing device or the yarn breakage processing device of each spinning drawing machine, the operability can be further improved.

In one embodiment, the melt spinning apparatus may be provided with a plurality of suction guns capable of sucking the plurality of filaments spun from the spinning device, and the number of the plurality of suction guns may be smaller than the number of the plurality of spinning tractors. In this configuration, when yarn hanging is performed in one spinning machine in a state where yarn hanging occurs at the same timing in a plurality of spinning machines, the yarn spun from the spinning device cannot be received by the suction gun in the other spinning machines. Therefore, in the configuration in which the number of the plurality of suction guns is smaller than the number of the plurality of spinning tractors, the suction units of the yarn breakage processing devices provided in the spinning tractors hold the plurality of yarns cut in the cutting units, so that the standby time for using the suction guns is not generated, and the operability can be improved.

In one embodiment, the cutting portion may be disposed near the suction port of the suction portion. In this configuration, the plurality of wires cut by the cutting unit can be easily guided to the suction port of the suction unit.

In one embodiment, the wire breakage processing device and the cutting portion may be fixed to one side portion of the same member in the traction device. In this configuration, the plurality of wires cut by the cutting unit can be easily guided to the suction port of the suction unit.

In one embodiment, the side surface of one side portion may intersect the arrangement direction, and a work area in which an operator is located when performing a cutting work may be provided on one side of the suction portion in an orthogonal direction orthogonal to the arrangement direction in a horizontal plane, and a cutting portion may be provided on the other side of the suction portion. In this configuration, the work area and the cutting portion face each other in the orthogonal direction, and therefore the cutting portion does not become an obstacle when the yarn is hung by the suction gun.

In one embodiment, the cutting portion may be disposed at a position farther from the side surface than the suction port of the suction portion in the arrangement direction when viewed from one side toward the other side in the orthogonal direction. In this configuration, when the worker performs work in the work area, the suction portion does not become an obstacle when the plurality of wires cut by the cutting portion are guided to the suction port of the suction portion. Therefore, the plurality of wires cut by the cutting portion can be easily guided to the suction port of the suction portion.

In one embodiment, the cutting section may include a 1 st edge having a 1 st edge portion and a 2 nd edge having a 2 nd edge portion, the 1 st edge line of the edge of the 1 st edge portion and the 2 nd edge line of the edge of the 2 nd edge portion intersecting each other as viewed from an overlapping direction in which the 1 st edge and the 2 nd edge portion overlap each other, a crossing section is formed in which the 1 st edge portion and the 2 nd edge portion cross each other, and the cutting section may be provided so that the crossing section is visible when viewed from one side to the other side in an orthogonal direction in which the arrangement direction is orthogonal to the overlapping direction and in which the arrangement direction is orthogonal to the horizontal plane. In this configuration, the operator located in the work area can easily identify the intersecting portion in the cut portion, and thus can easily perform work on the cut portion.

In one embodiment, the intersecting portion may be located above the suction portion in the vertical direction. In this configuration, the plurality of wires cut by the cutting unit can be easily guided to the suction port of the suction unit.

In one embodiment, the cutting portion may cut the plurality of wires entering the crossing portion from above. In this configuration, the operator can cut the plurality of wires by moving the plurality of wires from the upper side to the lower side with respect to the cutting portion. Therefore, the plurality of wires can be easily cut.

In one embodiment, the 1 st and 2 nd edges may be inclined such that the upper portions of the 1 st and 2 nd edges are located on the other side in the orthogonal direction and the lower portions of the 1 st and 2 nd edges are located on the one side in the orthogonal direction as viewed in the arrangement direction. When the operator performs the cutting operation, the operator holds the plurality of wires with both hands to bundle the plurality of wires, inserts the plurality of wires in a bundle shape at a portion between one hand and the other hand into the cutting portion, and moves the plurality of wires from the top downward. At this time, the bundle of the plurality of wires is pressed down by moving the hand on the other side downward in a state where the height position of the hand on the one side is fixed. In this case, when the 1 st blade and the 2 nd blade are inclined as described above, the shearing force is easily applied to the plurality of wires, and therefore the plurality of wires can be easily cut.

In one embodiment, the yarn breakage processing device and the cutting unit may be fixed to the same member in the traction device, the cutting unit may include a mounting member for mounting the 1 st blade and the 2 nd blade to the member, and the mounting member may include: a fixing portion fixed to the member; an extension portion connected to the fixing portion and extending along the arrangement direction; and a support portion connected to the extension portion and extending in the up-down direction, and connected to the lower portions of the 1 st and 2 nd blades to support the 1 st and 2 nd blades. In this configuration, the extending portion extends along the arrangement direction, and the supporting portion connected to the extending portion extends in the up-down direction. In this way, the extension portion and the support portion are configured not to have portions protruding in the orthogonal direction as viewed in the arrangement direction, and therefore, the attachment member can be prevented from being blocked or the plurality of wires can be caught by the attachment member during the cutting operation.

In one embodiment, the wire breakage processing device and the cutting portion may be fixed to one side portion of the same member in the traction device, the member may be provided with a 1 st operation portion to be operated by the operator, the 1 st operation portion may be provided on the other side portion different from the one side portion to which the cutting portion is fixed in the member, and the work area where the operator is located when performing the cutting work may be provided at a position where the operation portion is operable. In this configuration, the yarn cutting operation and the operation of the operation unit can be performed in the operation region. Therefore, the working area can be effectively utilized in a limited space such as a factory where the melt spinning apparatus is installed.

In one embodiment, the drawing device may have a winding portion for winding a plurality of wires, and the winding portion may be provided with a 2 nd operation portion for an operator to operate, and the 1 st operation portion and the 2 nd operation portion may be disposed in the same direction. In this configuration, the operator can operate the 1 st operation unit or the 2 nd operation unit while checking (visually) both of the 1 st operation unit and the 2 nd operation unit.

In one embodiment, the plurality of spinning tractors may be arranged along the arrangement direction, a passage through which an operator passes may be provided so as to extend along the arrangement direction, a work area in which the operator is located when performing the cutting work may be provided on the passage, the yarn breakage processing device and the cutting portion may be fixed to one side portion of the same member in the traction device, and a side surface of the one side portion to which the cutting portion is fixed may intersect with the extending direction of the passage. In this configuration, the passage is provided in a straight line so as to extend in the arrangement direction, and thus the operator can easily move the passage. Further, since the cutoff portion is not disposed in the passage, contact between the worker passing through the passage and the cutoff portion can be avoided.

According to one aspect of the present invention, when a plurality of spinning tractors are provided, operability and safety can be improved when a plurality of filaments spun from a spinning device are hung on the spinning tractors, and a defect of a cutter of a filament breakage processing device can be prevented.

Detailed Description

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same or corresponding elements are denoted by the same reference numerals, and overlapping description thereof is omitted.

Fig. 1 is a schematic side view of a melt spinning apparatus of one embodiment. Fig. 2 is a schematic front view of the spinning tractor. For convenience of explanation, the front-rear direction is set in fig. 1, and the left-right direction is set in fig. 2.

The melt spinning apparatus 100 shown in fig. 1 and 2 is installed in a factory or the like. As shown in fig. 2, the melt spinning apparatus 100 includes a plurality of spinning tractors 1 and a cutting unit (see fig. 3). The plurality of spinning tractors 1 are arranged in a plurality in the left-right direction. In fig. 2, two spinning tractors 1 are shown. The melt spinning apparatus 100 is provided with a plurality of suction guns 110. In the melt spinning apparatus 100, the number of the plurality of spinning tractors 1 is larger than the number of the plurality of suction guns 110.

The spinning tractors 1 have the same configuration. Hereinafter, the constitution of the spinning machine 1 will be described in detail by taking one spinning machine as an example. As shown in fig. 1 and 2, the spinning machine 1 includes a spinning device 2, a drawing device 3, and a yarn breakage processing device 4. The spinning machine 1 draws the plurality of yarns Y spun from the spinning device 2 in the drawing device 3, and winds the plurality of yarns Y around the plurality of bobbins B, respectively, to form a plurality of packages P.

The spinning device 2 spins out a plurality of threads Y. The spinning device 2 is arranged above the drawing device 3. The plurality of threads Y are arranged to run in an arrangement direction. The arrangement direction is consistent with the left-right direction.

The drawing device 3 includes a 1 st godet 6, a 2 nd godet 7, a guide rail 8, a yarn regulating mechanism 9, and a winding unit 10.

The 1 st godet 6 and the 2 nd godet 7 draw the plurality of filaments Y spun from the spinning device 2. The 1 st godet 6 is disposed below the spinning device 2 in the up-down direction. The 1 st godet 6 is provided in the housing 20 (see fig. 4). The 1 st godet 6 rotates about a rotation axis extending in the left-right direction. The 1 st godet 6 is rotationally driven by a 1 st godet motor (not shown).

The 2 nd godet 7 is disposed at a position further to the rear than the 1 st godet 6. The 2 nd godet 7 rotates around a rotation axis extending in the left-right direction. The 2 nd godet roller 7 is rotationally driven by a 2 nd godet motor (not shown).

The 2 nd godet roller 7 is supported movably on the guide rail 8. The guide rail 8 is disposed obliquely to the front-rear direction such that one end portion in the longitudinal direction (left end portion in fig. 1) is downward and the other end portion in the longitudinal direction (right end portion in fig. 1) is upward. The 2 nd godet 7 is connected to a cylinder (not shown). The 2 nd godet 7 is moved along the guide rail 8 by a cylinder. Thereby, the 2 nd godet roller 7 can move between the winding position shown by the solid line in fig. 1 and the yarn hanging position shown by the one-dot chain line in fig. 1. The winding position is a position at which the yarn Y is wound. The yarn hanging position is a position closer to the 1 st godet 6 than the winding position, and is a position at the time of yarn hanging.

The thread regulating mechanism 9 is disposed above the 1 st godet 6. As shown in fig. 3, 4 and 5, the wire limiting mechanism 9 is provided at a side portion 20C of the housing 20. The thread regulating mechanism 9 has a 1 st regulating portion 9A and a 2 nd regulating portion 9B. The 1 st restriction portion 9A is disposed above the 2 nd restriction portion 9B. The 1 st regulating portion 9A and the 2 nd regulating portion 9B define intervals between the plurality of filaments Y wound around the 1 st godet 6. The 1 st restriction portion 9A and the 2 nd restriction portion 9B stabilize the running of the plurality of wires Y and restrict the plurality of wires Y aligned in the left-right direction from moving in the left-right direction.

As shown in fig. 1 and 2, the winding unit 10 includes a plurality of fulcrum guides 11, a plurality of traverse guides 12, a turntable 13, two bobbin holders 14, and a contact roller 15.

As shown in fig. 1, the plurality of fulcrum guides 11 are provided separately from the plurality of wires Y and are arranged in the front-rear direction. The plurality of fulcrum guides 11 are movably mounted to the guide wire member 16. The guide wire member 16 is disposed so that the longitudinal direction thereof extends in the front-rear direction. The guide wire member 16 is attached to the main body frame 19 via a support member 18 attached to the lower side thereof.

The plurality of traverse guides 12 are provided individually for the plurality of wires Y and are arranged in the front-rear direction. Each traverse guide 12 is driven by a traverse motor (not shown) to reciprocate in the front-rear direction. The yarn Y hooked on the traverse guide 12 traverses around the fulcrum guide 11.

The turntable 13 is a disk-shaped member. The turntable 13 rotates about a rotation axis extending in the front-rear direction. The turntable 13 is rotationally driven by a turntable motor (not shown). The respective axial directions of the two bobbin holders 14 extend in the front-rear direction. The two bobbin holders 14 are rotatably supported at the upper end and the lower end of the turntable 13, respectively. A plurality of bobbins B provided individually for the plurality of threads Y are arranged in the front-rear direction on each bobbin holder 14. The two bobbin holders 14 are each rotationally driven by a separate winding motor (not shown).

In the winding unit 10, when the upper bobbin holder 14 is rotationally driven, the yarn Y traversed by the traverse guide 12 is wound around the bobbin B to form the package P. After the formation of the package P is completed, the turntable 13 is rotated, thereby switching the up-down positions of the two bobbin holders 14. Thereby, the bobbin holder 14 positioned at the lower side is moved to the upper side, and the yarn Y can be wound on the bobbin B attached to the bobbin holder 14 to form the package P. The bobbin holder 14 located above is moved to the lower side, and the completed package P can be recovered from the bobbin holder 14.

The contact roller 15 is disposed above the upper bobbin holder 14. The contact roller 15 rotates about a rotation axis extending in the front-rear direction. The contact roller 15 is in contact with the surface of the package P formed by winding the yarn Y around the bobbin B mounted on the upper bobbin holder 14, and applies a contact pressure to the surface of the package P during winding of the yarn Y.

The yarn breakage processing device 4 operates to hold the plurality of yarns Y when the yarns are broken after the yarn winding in the drawing device 3 is completed. The yarn breakage processing device 4 is disposed above the yarn limiting mechanism 9. As shown in fig. 3, the wire breakage processing device 4 is provided in a housing (member) 20.

As shown in fig. 6, the wire breakage processing device 4 includes a holder 40, a suction device 41, and a cutter 42. The holder 40 serves as a base of the yarn breakage processing device 4, and is provided in the housing 20 (see fig. 4).

The suction device 41 sucks the plurality of wires Y cut by the cutter 42. The suction device 41 includes a holding portion 43, a suction portion 44, and a cylinder 45. The holding portion 43 and the suction portion 44 are cylindrical members. The suction portion 44 is held so as to be movable forward and backward with respect to the holding portion 43, and the inside of the holding portion 43 communicates with the inside of the suction portion 44. The air tightness is maintained between the outside of the suction portion 44 and the inside of the holding portion 43 so as not to leak air. A suction port 44A for sucking the cut-off plurality of threads Y is formed at the tip end of the suction portion 44. The holding portion 43 is fixed to the holder 40 so that the advancing and retreating direction of the suction portion 44 is parallel to the arrangement direction (left-right direction) of the plurality of wires Y. The suction portion 44 penetrates the holder 40, and the suction port 44A at the distal end protrudes from the opening 40A of the holder 40.

A suction source 48 (see fig. 2) is connected to the suction device 41. The suction source 48 generates an air flow for suction. Suction force for sucking the cut plurality of threads Y is generated at the suction port 44A by the suction source 48. The suction source 48 is connected to the suction device 41 via a solenoid valve (not shown).

The cylinder 45 is fixed to the bracket 40. The cylinder 45 has a piston rod 46. The distal end of the piston rod 46 is connected to a connecting member 47 fixed to the suction unit 44. The cylinder 45 is driven by a driving device 49 (see fig. 2). The cylinder 45 is advanced and retracted by the driving device 49, whereby the suction portion 44 moves between the protruding 1 st position P1 (see fig. 7 (C)) and the 2 nd position P2 (see fig. 7 (a)) retracted from the 1 st position P1. As shown in fig. 3 and 4, the suction portion 44 protrudes from the side portion 20C of the housing 20 at the 1 st position P1.

As shown in fig. 6, the cutter 42 cuts the plurality of wires Y at the time of breakage after the completion of winding of the wires in the drawing device 3. The cutter 42 advances and retreats together with the suction unit 44 of the suction device 41, and cuts the plurality of wires Y on the upstream side of the wire limiting mechanism 9 when the suction unit 44 protrudes. Specifically, as shown in fig. 7 (a), 7 (B), and 7 (C), the cutter 42 cuts the thread Y with the movement of the suction portion 44 protruding from the 2 nd position P2 to the 1 st position P1. At this time, the suction unit 44 sucks the yarn Y cut by the cutter 42. As shown in fig. 7 (D) and 7 (E), the cutter 42 moves backward from the 1 st position P1 to the 2 nd position P2 together with the suction unit 44 that sucks the plurality of wires Y.

The cutter 42 continuously cuts the plurality of threads Y aligned in the alignment direction one at a time or a plurality of threads at a time. Here, continuously cutting the plurality of threads Y one at a time or a plurality of threads each time means gradually cutting the plurality of threads Y which are not bundled. That is, the continuous cutting of the plurality of threads Y one at a time or a plurality of threads Y at a time means that the cutter 42 cuts the plurality of threads Y while contacting the one or the plurality of threads Y a plurality of times as the suction unit 44 moves while the suction unit 44 moves from the 2 nd position P2 to the 1 st position P1. Thus, the operation is different from the operation of cutting the bundle of the plurality of wires Y by one operation.

As shown in fig. 3, 4 and 5, the cutting unit 5 is used for an operator to cut the plurality of wires Y. The cutting unit 5 cuts the bundle of the plurality of threads Y before the threads are hung on the drawing device 3. As shown in fig. 8, the cutting section 5 includes a 1 st blade (cutting blade) 50, a 2 nd blade (cutting blade) 51, a guide member 52, and a mounting member 54. The state of the cutting portion 5 shown in fig. 7 is defined as the front surface of the cutting portion 5.

The 1 st blade 50 is constituted by a 1 st blade portion 50A as a tip portion thereof and a 1 st base portion 50B connected to the 1 st blade portion 50A. The 2 nd blade 51 is constituted by a 2 nd blade portion 51A as a tip portion thereof and a 2 nd base portion 51B connected to the 2 nd blade portion 51A.

The 1 st blade 50 and the 2 nd blade 51 are disposed in a state in which the 1 st base 50B and the 2 nd base 51B overlap with each other, with the 1 st blade 50 being the upper side and the 2 nd blade 51 being the lower side. The 1 st ridge 50R of the edge of the 1 st edge 50 and the 2 nd ridge 51R of the edge of the 2 nd edge 51 intersect at their intermediate portions. Thus, the cutting portion 5 has an intersection C where the 1 st blade 50 and the 2 nd blade 51 intersect. The 1 st edge 50A of the 1 st edge 50 has an edge angle θ1 of 15 degrees or more and less than 30 degrees. The edge angle θ2 of the 2 nd edge portion 51A of the 2 nd edge 51 is 15 degrees or more and less than 30 degrees. In the present embodiment, the edge angle θ1 of the 1 st edge 50 is equal to the edge angle θ2 of the 2 nd edge 51. A gap is provided between the 1 st edge 50A of the 1 st edge 50 and the 2 nd edge 51A of the 2 nd edge 51. That is, a part of the lower surface of the 1 st blade 50A and a part of the upper surface of the 2 nd blade 51A face each other with a gap therebetween.

The guide member 52 is disposed so as to overlap the 1 st blade 50 on the back side of the paper surface in fig. 8. The guide member 52 guides the plurality of wires Y to the crossing portion C formed at the crossing portion C of the 1 st blade portion 50A and the 2 nd blade portion 51A of the 1 st blade 50 and the 2 nd blade 51. The guide member 52 is formed in a substantially V-shape so as to guide the plurality of wires Y to the crossing portion C where the 1 st blade 50 crosses the 2 nd blade 51.

As shown in fig. 3, 4 and 5, the mounting member 54 mounts the 1 st blade 50 and the 2 nd blade 51 to the housing 20. The mounting member 54 has a fixing portion 54A, an extending portion 54B, and a supporting portion 54C. The fixing portion 54A, the extending portion 54B, and the supporting portion 54C are integrally formed. The mounting member 54 has, for example, a substantially L-shape. The attachment member 54 is formed by bending a metal plate-like member. The thickness (plate thickness) of the mounting member 54 is, for example, 6mm. The mounting member 54 has the following strength: in the cutting operation of the plurality of wires Y by the operator, the load (load) applied to the cutting portion 5 can be endured.

The fixing portion 54A is a portion fixed to a side portion 20C (described later) of the housing 20. The fixing portion 54A is fixed to the side portion 20C. The fixing portion 54A is fixed to the side portion 20C by screws, welding, or the like.

The extension 54B is a portion connected to the fixing portion 54A and extending in the left-right direction. The extension 54B is connected to the front end of the fixing portion 54A. The support portion 54C is connected to the extension portion 54B and extends in the up-down direction. The support portion 54C is connected to the right end portion of the extension portion 54B. The support portion 54C is connected to the lower portions of the 1 st blade 50 and the 2 nd blade 51, and supports the 1 st blade 50 and the 2 nd blade 51. The extending portion 54B and the supporting portion 54C are located on the front side of the intersection C of the 1 st blade portion 50A and the 2 nd blade portion 51A as viewed from the left-right direction. That is, the extending portion 54B and the supporting portion 54C do not have a portion located rearward of the intersecting portion C as viewed from the left-right direction.

The cutting portion 5 is fixed to the housing 20 of the traction device 3. The cutting section 5 is fixed to a housing 20 provided with the broken wire processing device 4. That is, the wire breakage processing device 4 and the cutting portion 5 are fixed to the same member. In the present embodiment, the cutting unit 5 is provided in the housing 20 of the drawing device 3 of each of the plurality of spinning drawing machines 1.

The housing 20 is provided at one end in the longitudinal direction of the guide rail 8. The case 20 includes a front portion (other side portion) 20A provided with an operation portion (1 st operation portion) 22, a rear portion 20B disposed toward the winding portion 10 side, and a pair of side portions 20C, 20D connecting the front portion 20A and the rear portion 20B. The pair of side portions 20C, 20D are opposed in the left-right direction. The side surface 20S of the side portion 20C is orthogonal to the left-right direction (arrangement direction). A wire pipe 21 for discharging the wire is provided at the side portion 20D.

The front portion 20A is disposed toward the work area a. The work area a is an area in which an operator is located when performing a cutting work. As shown in fig. 9, the work area a is provided on the front side (one side) with respect to the suction portion 44 of the yarn breakage processing device 4 in the front-rear direction (orthogonal direction) orthogonal to the arrangement direction (left-right direction) of the plurality of yarns Y in the horizontal plane. The working area a is an area (space) provided on the passage T in front of the housing 20. In the present embodiment, as shown in fig. 2, the spinning tractor 1 is arranged in a row in the left-right direction (arrangement direction), and the passage T through which the operator passes also extends in the left-right direction. The extending direction of the passage T is orthogonal (intersecting) to the side surface 20S of the side portion 20C of the housing 20. The work area a is provided on the passage T extending in the left-right direction. In the present embodiment, the front portion 20A of the housing 20 faces the passage T side. Therefore, in the working area a, the operation portion 22 provided at the front portion 20A of the housing 20 can be operated. In fig. 9, for convenience of explanation, the work area a is shown as a rectangular shape by a broken line, but the shape of the work area a is not shown, but is a rectangular shape.

As shown in fig. 3, 4, and 5, the cut-off portion 5 is fixed to a side portion (one side portion) 20C of the case 20. The cutting section 5 is configured such that the cutting portion of the plurality of wires Y in the cutting section 5, that is, the intersection C of the 1 st blade 50 and the 2 nd blade 51 is located at a position separated from the side portion 20C by the attachment member 54.

The cutting portion 5 is disposed near the suction port 44A of the suction portion 44 located at the 1 st position P1 (see fig. 7C). The vicinity means, for example, a distance of 100mm or less from the suction port 44A. Specifically, the suction port 44A is spaced from the upper end portion of the guide member 52 of the cutting unit 5 in the front-rear direction. In the present embodiment, the distance between the suction port 44A and the upper end portion of the guide member 52 of the cutting portion 5 in the front-rear direction is, for example, about 80mm.

The cutting unit 5 is disposed so that the front face faces the work area a side. The cutting unit 5 is arranged so that the operator can visually confirm the intersection C of the 1 st blade 50 and the 2 nd blade 51 when the operator is located in the work area a. Specifically, the cutting portion 5 is arranged such that the intersecting portion C is visible when the overlapping direction in which the 1 st blade 50 overlaps the 2 nd blade 51 is orthogonal to the left-right direction and viewed from front to rear in the front-rear direction. The cutting section 5 cuts the plurality of threads Y entering the crossing section C from above. The direction in which the plurality of filaments Y enter the cutting portion 5 is the up-down direction.

The intersection C between the 1 st blade 50 and the 2 nd blade 51 of the cutting portion 5 is located above the suction portion 44 in the vertical direction. As shown in fig. 4, the cutting portion 5 is disposed at a position farther from the side portion 20C in the left-right direction than the tip (suction port 44A) of the suction portion 44 located at the 1 st position P1 in the wire breakage processing device 4.

As shown in fig. 5, the 1 st blade 50, the 2 nd blade 51, and the guide member 52 of the cutting portion 5 are disposed obliquely as viewed from the left-right direction. Specifically, the upper parts of the 1 st blade 50, the 2 nd blade 51, and the guide member 52 are positioned on the rear side, and the lower parts of the 1 st blade 50, the 2 nd blade 51, and the guide member 52 are positioned on the front side when viewed from the left-right direction. That is, the upper portions of the 1 st blade 50, the 2 nd blade 51, and the guide member 52 are inclined in a direction away from the work area a. It can be said that the distance in the front-rear direction between the positions of the 1 st blade 50, the 2 nd blade 51, and the lower portion of the guide member 52 and the position of the suction portion 44 is shorter than the distance in the front-rear direction between the positions of the 1 st blade 50, the 2 nd blade 51, and the upper portion of the guide member 52 and the position of the suction portion 44, as viewed from the left-right direction.

The 1 st blade 50, the 2 nd blade 51, and the guide member 52 are inclined in a range of more than 0 ° and less than 90 ° with respect to the up-down direction, for example. The angle is 0 ° in the case where the 1 st blade 50, the 2 nd blade 51, and the guide member 52 are along the up-down direction, and 90 ° in the case where the 1 st blade 50, the 2 nd blade 51, and the guide member 52 are along the front-back direction. In the present embodiment, the inclination angle θ is, for example, 35 °.

Next, the electrical configuration of the spinning machine 1 will be described. The spinning tractor 1 is provided with a control device 23. The control device 23 is a processor mounted with an integrated circuit or a computer system equipped with the processor. The control device 23 is a part for controlling various operations of the spinning machine 1, and is composed of CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory) and the like, an input/output interface and the like.

The control device 23 controls the 1 st godet motor that drives the 1 st godet roller 6, the 2 nd godet motor that drives the 2 nd godet roller 7, and the cylinder. Thereby, the 1 st godet 6 and the 2 nd godet 7 are driven. The control device 23 controls an electromagnetic valve (not shown) provided in the suction device 41. Thereby, the solenoid valve is driven to open and close. The control device 23 controls the driving device 49. Thereby, the cylinder 45 of the suction device 41 is driven, and the piston rod 46 attached to the cylinder 45 advances and retreats, whereby the suction portion 44 connected thereto advances and retreats in the left-right direction. The control device 23 sends a signal to the control unit 24 of the winding unit 10. The control unit 24 controls the traverse guide 12, the turntable 13, the bobbin holder 14, and the like provided in the winding unit 10.

Next, a method of hanging the plurality of filaments Y spun from the spinning device 2 to the drawing device 3 in the spinning machine 1 will be described. Here, the case where the melt spinning apparatus 100 is configured to simultaneously carry out yarn hanging in the plurality of spinning tractors 1 will be described.

First, a method of temporarily holding a plurality of filaments Y spun from the spinning device 2 in the filament breakage processing device 4 will be described. The operator obtains a plurality of filaments Y spun from the spinning device 2 below the spinning device 2 (working area a). Next, the operator holds the plurality of wires Y with both hands to bundle the plurality of wires Y, positions the cutting portion 5 between one hand and the other hand in the front-rear direction, and inserts the plurality of wires Y in a bundle shape at a portion between the one hand and the other hand into the cutting portion 5. Then, the operator presses the bundle of the plurality of wires Y against the cutting unit 5 to collectively cut the bundle of the plurality of wires Y at once. Specifically, the hand on the rear side is moved downward while fixing the height position of the hand on the front side, whereby the bundle of the plurality of wires Y is pressed down. After cutting, the operator brings the plurality of wires Y to the suction port 44A of the suction unit 44 of the wire breakage processing device 4, and sucks the suction port 44A. Thereby, the plurality of wires Y whose ends are cut are held in the wire breakage processing device 4. The operator also causes the yarn breakage processing device 4 to temporarily hold the plurality of yarns Y in the other spinning machine 1 by the same method.

The method of cutting the plurality of filaments Y in the cutting unit 5 is not limited to the above method, and may be cut by other methods. The operator may apply tension to the plurality of wires Y to cut them.

Next, a method of hanging the plurality of yarns Y held by the yarn breakage processing device 4 to the drawing device 3 will be described. The operator cuts the plurality of threads Y held by the thread breakage processing device 4 with scissors, and sucks the plurality of threads Y spun from the spinning device 2 with the suction gun 110. The operator sets the plurality of wires Y sucked by the suction gun 110 in the wire limiting mechanism 9, and winds and hangs the wires Y in the order of the 1 st godet 6 and the 2 nd godet 7. At this time, the 2 nd godet 7 is located at the yarn hanging position. Thereafter, the plurality of wires Y are set in the winding unit 10 in a predetermined order.

As described above, the melt spinning apparatus 100 of the present embodiment includes the cutting unit 5 used for the operator to cut the plurality of filaments Y. That is, the melt spinning apparatus 100 includes a dedicated cutting unit 5, and the cutting unit 5 is configured to cut the bundle of the plurality of filaments Y before the filaments are drawn by the drawing device 3 when the plurality of filaments Y spun from the spinning device 2 are drawn by the drawing device. Accordingly, the operator can collectively cut the bundle of the plurality of wires Y at one time by the cutting unit 5 without using a cutting tool or a cutter. Therefore, when the plurality of spinning tractors 1 are provided, operability and safety can be improved when the plurality of filaments spun from the spinning device 2 are drawn into the traction device 3, and occurrence of a defect in the cutter of the filament breakage processing device can be prevented.

In the melt-spinning apparatus 100 of the present embodiment, the suction unit 44 of the yarn breakage processing device 4 holds the plurality of yarns Y cut in the cutting unit 5. Therefore, even when the yarn Y spun from the spinning device 2 cannot be received by the suction gun 110, the yarn Y can be stored in the suction unit 44.

In the melt spinning apparatus 100 of the present embodiment, the cutting section 5 is provided in each of the plurality of spinning tractors 1 to the drawing device 3. In this configuration, since the plurality of filaments Y can be cut by the cutting portion 5 provided in the drawing device 3 of each spinning drawing machine 1, the operability can be further improved.

The melt spinning apparatus 100 of the present embodiment includes a plurality of suction guns 110 capable of sucking the plurality of filaments Y spun from the spinning device 2. The number of the plurality of suction guns 110 is smaller than the number of the plurality of spinning tractors 1. In this configuration, in a case where yarn hanging occurs at the same timing in the plurality of spinning machines 1, when yarn hanging is performed in one spinning machine 1, the yarn Y spun from the spinning device 2 cannot be received by the suction gun 110 in the other spinning machines 1. Therefore, in the configuration in which the number of the plurality of suction guns 110 is smaller than the number of the plurality of spinning machines 1, the suction units 44 of the yarn breakage processing devices 4 included in the spinning machines 1 hold the plurality of yarns Y cut in the cutting units 5, so that the standby time for using the suction guns 110 is not generated, and the operability can be improved.

In the melt-spinning apparatus 100 of the present embodiment, the cutting section 5 is disposed in the vicinity of the suction port 44A of the suction section 44 of the yarn-break processing device 4. In the present embodiment, the suction portion 44 of the wire breakage processing device 4 is provided so as to be movable in the left-right direction between a 1 st position P1 protruding and a 2 nd position P2 retreating from the 1 st position P1. The cutting portion 5 is disposed near the suction port 44A of the suction portion 44 located at the 1 st position P1. In this configuration, the plurality of wires Y cut by the cutting unit 5 can be easily guided to the suction port 44A of the suction unit 44.

In the melt spinning apparatus 100 of the present embodiment, the yarn breakage processing device 4 and the cutting portion 5 are fixed to the side portion 20C of the housing 20 in the drawing device 3. In this configuration, the plurality of wires Y cut by the cutting unit 5 can be easily guided to the suction port 44A of the suction unit 44.

In the melt spinning apparatus 100 of the present embodiment, a work area a in which an operator performs a cutting operation is provided on the front side of the suction portion 44 with respect to the yarn breakage processing device 4 in the front-rear direction, and the cutting portion 5 is provided on the rear side of the suction portion 44. In this configuration, the work area a and the cutting portion 5 face each other in the front-rear direction, and therefore the cutting portion does not become an obstacle when the yarn is hung by the suction gun 110.

In the melt-spinning apparatus 100 of the present embodiment, the cutting portion 5 is disposed at a position farther from the side surface 20S in the left-right direction than the suction port 44A of the suction portion 44 of the yarn breakage processing device 4, as viewed from the front to the rear in the front-rear direction. In this configuration, when the operator performs work in the work area a, the suction unit 44 does not become an obstacle when the plurality of wires Y cut by the cutting unit 5 are guided to the suction port 44A of the suction unit 44. Therefore, the plurality of wires cut by the cutting unit 5 can be easily guided to the suction port 44A of the suction unit 44.

In the melt spinning apparatus 100 of the present embodiment, the cutting section 5 includes a 1 st blade 50 having a 1 st blade portion 50A, and a 2 nd blade 51 disposed to overlap the 1 st blade 50 and having a 2 nd blade portion 51A. The 1 st ridge line 50R of the edge of the 1 st edge portion 50A intersects with the 2 nd ridge line 51R of the edge of the 2 nd edge portion 51A, as viewed in the overlapping direction in which the 1 st edge 50 overlaps with the 2 nd edge 51, and a crossing portion C is formed in which the 1 st edge portion 50A intersects with the 2 nd edge portion 51A. In the melt spinning apparatus 100, a working area a in which an operator is located when performing a cutting operation is provided on the front side of the suction portion 44 in the front-rear direction. In the melt spinning apparatus 100, the cutting portion 5 is fixed to the side portion 20C of the housing 20 so that the intersecting portion C can be observed when viewed from front to rear in the front-rear direction and in the right-left direction orthogonal to the above-described overlapping direction of the cutting portion 5.

In the melt-spinning apparatus 100 of the present embodiment, the intersection C where the 1 st blade 50 and the 2 nd blade 51 intersect is located above the suction portion 44 in the vertical direction. In this configuration, the plurality of wires Y cut at the 1 st blade 50 and the 2 nd blade 51 of the cutting portion 5 can be easily guided to the suction port 44A of the suction portion 44.

In the melt spinning apparatus 100 of the present embodiment, the cutting section 5 cuts the plurality of filaments Y entering the crossing section C from above. In this configuration, the operator can cut the plurality of wires Y by moving the plurality of wires Y downward with respect to the cutting unit 5. Therefore, the plurality of wires Y can be easily cut.

In the melt-spinning apparatus 100 of the present embodiment, the 1 st blade 50 and the 2 nd blade 51 are inclined such that upper portions of the 1 st blade 50 and the 2 nd blade 51 are located on the rear side in the front-rear direction and lower portions of the 1 st blade 50 and the 2 nd blade 51 are located on the front side in the front-rear direction as viewed from the left-right direction. When the operator performs the cutting operation, the operator holds the plurality of wires Y with both hands to bundle the plurality of wires Y, inserts the plurality of wires Y bundled at a portion between one hand and the other hand into the cutting portion 5, and moves the plurality of wires Y downward from above. At this time, the bundle of the plurality of wires Y is pressed down by moving the hand on the rear side downward in a state where the height position of the hand on the front side is fixed. In this case, when the 1 st blade 50 and the 2 nd blade 51 are inclined as described above, a shearing force is easily applied to the plurality of wires Y, and therefore the plurality of wires Y can be easily cut.

In the melt spinning apparatus 100 of the present embodiment, the cutting portion 5 has the attachment member 54 for attaching the 1 st blade 50 and the 2 nd blade 51 to the side portion 20C of the housing 20. The mounting member 54 has: a fixing portion 54A fixed to the side portion 20C; an extension 54B connected to the fixing portion 54A and extending in the left-right direction; and a support portion 54C connected to the extension portion 54B and extending in the up-down direction, and connected to the lower portion of the holding member 53 to support the holding member 53. In this configuration, the extension 54B extends in the left-right direction, and the support 54C connected to the extension 54B extends in the up-down direction. In this way, the extending portion 54B and the supporting portion 54C are configured not to have a portion protruding in the front-rear direction as viewed from the left-right direction, and therefore, the attachment member 54 can be prevented from being blocked or the plurality of wires Y can be caught by the attachment member 54 at the time of the cutting operation. In the structure in which the fixing portion 54A is fixed to the side portion 20C, the extension portion 54B may not be increased when the cut portion 5 is disposed in the vicinity of the suction port 44A of the suction portion 44. This ensures strength of the mounting member 54 that can withstand the load applied to the cutting unit 5 during the cutting operation.

In the melt spinning apparatus 100 of the present embodiment, the housing 20 is provided with an operation portion 22 to be operated by an operator. The operation portion 22 is provided at a front portion 20A of the case 20 different from the side portion 20C to which the cutting portion 5 is fixed. The work area a in which the operator is located when performing the cutting work is provided at a position where the operator can operate the operation unit 22. In this configuration, in the work area a, the cutting operation of the yarn Y and the operation of the operation unit 22 can be performed. Thus, the work area a can be effectively utilized in a limited space such as a factory where the melt spinning apparatus 100 is provided.

In the melt spinning apparatus 100 of the present embodiment, the plurality of spinning tractors 1 are arranged in the left-right direction. The melt spinning apparatus 100 is provided with a passage T through which an operator passes so as to extend in the left-right direction. The work area a in which the operator is located when performing the cutting work is provided on the passage T. In this configuration, the passage T is provided in a straight line so as to extend in the left-right direction, and thus the operator can easily move the passage T. Further, since the shut-off portion is not disposed in the passage T, the operator passing through the passage T can be prevented from coming into contact with the shut-off portion.

The embodiments of the present invention have been described above, but the present invention is not necessarily limited to the above embodiments, and various modifications can be made without departing from the gist thereof.

In the above embodiment, the description has been made taking, as an example, a case where the cutting portion 5 is disposed on the rear side with respect to the suction portion 44 in the side portion 20C of the case 20.

In the above embodiment, the embodiment has been described taking, as an example, a configuration in which the cutting portion 5 has the 1 st blade 50, the 2 nd blade 51, the guide member 52, and the attachment member 54. However, the cutting unit may have any configuration as long as the cutting unit can cut the bundles of the plurality of filaments Y collectively.

In the above embodiment, the description has been made by taking, as an example, a mode in which the cutting portion 5 is provided on the side portion 20C of the housing 20, that is, the traction device 3. However, the cutting unit 5 may be provided in the wire breakage processing device 4. The cutting unit 5 may be provided in the drawing device 3 and the wire breakage processing device 4. The cutting unit 5 may be provided in plural in each of the drawing device 3 and the wire breakage processing device 4.

In the above embodiment, the manner in which the fixing portion 54A of the attachment member 54 is fixed to the side portion 20C of the housing 20 has been described as an example. However, the fixing portion 54A may be fixed to an upper portion of the housing 20, for example.

In the above embodiment, the description has been given of the case where the cutting portion 5 is fixed to the side portion 20C of the housing 20 by the attachment member 54 as an example. However, the cutting portion 5 may be housed in the case 20 when not in use, and may protrude from the case 20 when in use.

In the above embodiment, the description has been made taking, as an example, a case where the cutting unit 5 is disposed with the front face facing the work area a side. However, the orientation of the cutting portion 5 is not limited thereto.

In the above embodiment, the embodiment in which the wire breakage processing device 4 has one cutter 42 is described as an example. However, the yarn cutting device 4 may have two or more cutters.

In the above embodiment, the embodiment in which the cutter 42 moves together with the suction portion 44 to cut the yarn Y in the yarn breakage processing device 4 is described as an example. However, the cutter may be fixed in the wire breakage processing device. In this configuration, for example, a guide mechanism or the like for guiding the plurality of wires to the cutter is provided, and the cutter cuts the plurality of wires guided to the cutter by the guide mechanism. The guide mechanism moves the plurality of wires in the alignment direction to guide the plurality of wires toward the cutter. The guide mechanism may guide the plurality of wires to the cutter by hooking the plurality of wires with a hook, or may guide the plurality of wires to the cutter by moving a predetermined portion that defines the interval between the plurality of wires Y in the arrangement direction. The yarn breakage processing device may further include a guide mechanism or the like for guiding the plurality of yarns to the cutter, wherein the plurality of yarns are guided to the cutter by the guide mechanism, and the cutter and the guide mechanism are moved relatively to cut the plurality of yarns by the cutter.

In the above embodiment, the embodiment in which the cutting section 5 is provided in each of the plurality of spinning tractors 1 is described as an example. However, one cutting unit 5 may be provided for each of the plurality of spinning machines 1. For example, as shown in fig. 10, in the spinning machine 1 disposed adjacently, only the cutting portion 5 may be provided in one spinning machine 1 (left side in the drawing), and the cutting portion 5 may not be provided in the other spinning machine 1 (right side in the drawing). In the example shown in fig. 10, in the spinning tractor 1 disposed adjacently, the yarn breakage processing devices 4 and the like are disposed in the housing 20 so as to face each other.

In the other spinning machine 1, when the yarn breakage processing device 4 temporarily holds the plurality of yarns Y spun from the spinning device 2, the plurality of yarns Y are cut by the cutting section 5 provided in the one spinning machine 1. After cutting, the operator brings the plurality of yarns Y to the suction port 44A of the suction unit 44 of the yarn breakage processing device 4 of the other spinning tractor 1, and sucks the suction port 44A.

In the above-described embodiment, as shown in fig. 2, the spinning machine 1 is arranged in the left-right direction, and the operation area a is provided in the passage T extending in the arrangement direction of the spinning machine 1, for example.
