Summary of the Invention

Problems to be Solved by the Invention

[0004] <00​​​​Therefore, multiple threads spun from the spinning machine are temporarily held in the suction section of the thread cutting device. One method of holding the threads in the thread cutting device is for an operator to receive the multiple threads spun from the spinning machine, cut the ends of the threads using a cutting tool (scissors, cutter, etc.), and then suck the threads into the suction section for holding. However, this method is inefficient and unsafe because the operator has to hold the cutting tool while working.

[0006] Another method for holding threads in a thread-cutting device is to cut multiple threads using the device's cutters (first cutter, second cutter) and then hold the cut threads by sucking them into a suction section. However, the cutters in a thread-cutting device cut multiple threads one or more at a time in a continuous (gradual) manner. Therefore, if the device is used to cut multiple threads bundled together all at once, it can cause problems such as damage to the cutters or a shortened lifespan. This may impair the cutters' intended function.

[0007] One aspect of the present invention aims to provide a melt spinning system that can improve work efficiency and safety when multiple yarns spun from a spinning machine are loaded onto a yarn take-up machine, when multiple spinning take-up machines are installed, and that can prevent malfunctions from occurring in the cutter of the yarn cutting device. [Means for solving the problem]

[0008] A melt spinning apparatus according to one aspect of the present invention comprises a plurality of spinning take-up machines and a cutting unit, each of the plurality of spinning take-up machines having a spinning device for spinning a plurality of yarns, a take-up device for taking up the plurality of yarns, and a yarn cutting device for temporarily storing the plurality of yarns, the cutting unit is a cutting unit used for cutting a plurality of yarns by an operator, capable of cutting a bundle of a plurality of yarns before they are put onto the take-up device, and is installed in at least one of the take-up device and the yarn cutting device, the yarn cutting device having at least one cutter for continuously cutting one or more of the plurality of yarns one by one along the arrangement direction in which the plurality of yarns are lined up, and a suction unit for holding the plurality of yarns cut by the cutter and the plurality of yarns cut by the cutting unit.

[0009] A melt spinning apparatus according to one aspect of the present invention is equipped with a cutting section used for cutting multiple threads by an operator. Specifically, the melt spinning apparatus is equipped with a dedicated cutting section for cutting bundles of multiple threads before they are threaded onto a take-up device when multiple threads spun from a spinning machine are threaded onto a take-up device. This allows the operator to cut bundles of multiple threads all at once using the cutting section without using cutting tools or cutters. Therefore, when multiple spinning take-up machines are installed, it is possible to improve work efficiency and safety when threading multiple threads spun from a spinning machine onto a take-up device, and to prevent malfunctions in the cutter of the thread cutting device.

[0010] Furthermore, in melt spinning equipment, the suction section of the yarn cutting device in each spinning take-up machine holds multiple yarns that have been cut by the cutting section. Therefore, even if the yarn spun from the spinning machine cannot be received by the suction gun, the yarn can be stored in the suction section.

[0011] In one embodiment, the cutting unit may be installed in at least one of the take-up device and the yarn cutting device in each of the multiple spinning take-up machines. In this configuration, multiple yarns can be cut in the cutting unit installed in the take-up device or yarn cutting device of each spinning take-up machine, thereby further improving work efficiency.

[0012] In one embodiment, the melt spinning equipment is equipped with multiple suction guns capable of sucking up multiple threads spun from the spinning device, and the number of suction guns installed may be less than the number of spinning take-up machines. In this configuration, when threading occurs at the same time in multiple spinning take-up machines, if threading is being performed in one spinning take-up machine, it may not be possible to receive the threads spun from the spinning device by the suction guns in the other spinning take-up machines. Therefore, in a configuration where the number of suction guns installed is less than the number of spinning take-up machines, the multiple threads cut at the cutting section are held in the suction section of the thread cutting device in each spinning take-up machine, eliminating waiting time for the use of the suction guns and thus improving work efficiency.

[0013] In one embodiment, the cutting section may be located near the suction port of the suction section. In this configuration, the multiple threads cut at the cutting section can be easily guided to the suction port of the suction section.

[0014] In one embodiment, the yarn cutting apparatus and the cutting unit may be fixed to one side of the same component in the take-up device. In this configuration, the multiple yarns cut in the cutting unit can be easily guided to the suction port of the suction unit.

[0015] In one embodiment, the side surfaces of one side intersect in the arrangement direction, and in an orthogonal direction perpendicular to the arrangement direction in the horizontal plane, a work area is provided on one side relative to the suction part where the worker is positioned during cutting, and a cutting part may be provided on the other side relative to the suction part. In this configuration, since the work area and the cutting part face each other in an orthogonal direction, the cutting part does not get in the way when threading with a suction gun.

[0016] In one embodiment, the cutting section may be positioned further from the side in the arrangement direction than the suction port of the suction section when viewed from one side to the other in a perpendicular direction. In this configuration, when an operator is working in the work area, the suction section does not get in the way when guiding the multiple threads cut at the cutting section to the suction port of the suction section. Therefore, the multiple threads cut at the cutting section can be easily guided to the suction port of the suction section.

[0017] In one embodiment, the cutting section comprises a first blade having a first cutting edge and a second blade positioned overlapping the first blade and having a second cutting edge. When viewed from the overlapping direction where the first and second blades overlap, the first ridge of the cutting edge of the first blade and the second ridge of the cutting edge of the second blade intersect, forming an intersection where the first and second blades intersect. The cutting section may be positioned such that the intersection is visible when viewed from one side to the other in an orthogonal direction where the arrangement direction and the overlapping direction are perpendicular to each other and the arrangement direction is perpendicular in the horizontal plane. In this configuration, an operator located in the work area can easily recognize the intersection in the cutting section, thus facilitating work on the cutting section.

[0018] In one embodiment, the intersection may be located above the suction section in the vertical direction. In this configuration, the multiple threads cut at the cutting section can be easily guided to the suction port of the suction section.

[0019] In one embodiment, the cutting section may cut multiple threads that enter the intersection from above. In this configuration, the operator can cut multiple threads by moving the multiple threads from top to bottom relative to the cutting section. Therefore, multiple threads can be easily cut.

[0020] In one embodiment, the first and second blades may be inclined such that, when viewed from the direction of arrangement, the upper parts of the first and second blades are located on the other side in the orthogonal direction, and the lower parts of the first and second blades are located on one side in the orthogonal direction. When performing a cutting operation, the operator grasps multiple threads with both hands, bundles them together, inserts the bundle of threads into the cutting section between one hand and the other, and moves the multiple threads from top to bottom. At this time, while keeping the height position of the hand on one side fixed, the operator pushes down the bundle of threads by moving the hand on the other side downward. When performing such an operation, if the first and second blades are inclined as described above, it becomes easier to apply shear force to the multiple threads, so that the multiple threads can be cut easily.

[0021] In one embodiment, the yarn cutting apparatus and the cutting unit are fixed to the same member in the take-up device, and the cutting unit has a mounting member for attaching the first blade and the second blade to the member, and the mounting member may have a fixing part fixed to the member, an extending part connected to the fixing part and extending in the direction of arrangement, and a support part connected to the extending part and extending in the vertical direction, and connected to the lower part of the first blade and the second blade to support the first blade and the second blade. In this configuration, the extending part extends in the direction of arrangement, and the support part connected to this extending part extends in the vertical direction. By configuring the system in such a way that the extending part and the support part do not have any parts that protrude in a direction perpendicular to the direction of arrangement, it is possible to prevent the mounting member from getting in the way during cutting work or multiple threads from getting caught on the mounting member.

[0022] In one embodiment, the yarn breakage processing device and the cutting unit are fixed to one side of the same member in the take-up device. The member is provided with a first operation unit operated by an operator. The first operation unit is provided on the other side of the member different from the side where the cutting unit is fixed. The working area where the operator is located during the cutting operation may be provided at a position where the operation unit can be operated. With this configuration, in the working area, it is possible to perform the yarn cutting operation and the operation of the operation unit. Therefore, in a limited space such as a factory where the melt spinning equipment is installed, the working area can be effectively utilized.

[0023] In one embodiment, the take-up device has a winding unit for winding a plurality of yarns. The winding unit is provided with a second operation unit operated by an operator, and the first operation unit and the second operation unit may be arranged to face the same direction. With this configuration, it is possible for the operator to operate the first operation unit or the second operation unit while checking (visually) both the first operation unit and the second operation unit.

[0024] In one embodiment, a plurality of spinning take-up machines are arranged along the arrangement direction, and a passage for the operator to pass through is provided so as to extend along the arrangement direction. The working area where the operator is located during the cutting operation is provided on the passage. The yarn breakage processing device and the cutting unit are fixed to one side of the same member in the take-up device, and the side surface of the side where the cutting unit is fixed and the extending direction of the passage may intersect. With this configuration, since the passage is provided linearly so as to extend along the arrangement direction, the operator can move easily. Also, since the cutting unit is not arranged on the passage, it is possible to avoid the operator passing through the passage from contacting the cutting unit.

[0025] According to one aspect of the present invention, when a plurality of spinning take-up machines are installed, it is possible to improve the workability and safety when hanging a plurality of yarns spun from the spinning device on the spinning take-up machines, and it is possible to prevent a malfunction from occurring in the cutter of the yarn breakage processing device.

Modes for Carrying Out the Invention

[0027] 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 duplicate descriptions are omitted.

[0028] Figure 1 is a schematic side view of a melt spinning facility according to an embodiment. Figure 2 is a schematic front view of a yarn take-up machine. For the sake of convenience of explanation, the front-rear direction is set in Figure 1, and the left-right direction is set in Figure 2.

[0029] The melt spinning equipment 100 shown in Figures 1 and 2 is installed in a factory or the like. As shown in Figure 2, the melt spinning equipment 100 comprises multiple spinning take-up machines 1 and a cutting section (see Figure 3). Multiple spinning take-up machines 1 are installed side by side in the left-right direction. Figure 2 shows two spinning take-up machines 1. The melt spinning equipment 100 is equipped with multiple suction guns 110. In the melt spinning equipment 100, the number of spinning take-up machines 1 is greater than the number of suction guns 110.

[0030] Each of the multiple spinning take-up machines 1 has a similar configuration. Below, the configuration of one spinning take-up machine 1 will be described in detail as an example. As shown in Figures 1 and 2, the spinning take-up machine 1 comprises a spinning device 2, a take-up device 3, and a yarn cutting device 4. The spinning take-up machine 1 takes up multiple yarns Y spun from the spinning device 2 with the take-up device 3, and winds the multiple yarns Y onto multiple bobbins B to form multiple packages P.

[0031] The spinning machine 2 spins multiple threads Y. The spinning machine 2 is located above the take-up machine 3. The multiple threads Y travel in a line in the direction of arrangement. The direction of arrangement coincides with the left-right direction.

[0032] The take-up device 3 comprises a first godet roller 6, a second godet roller 7, a guide rail 8, a thread regulating mechanism 9, and a winding section 10.

[0033] The first godet roller 6 and the second godet roller 7 take up multiple yarns Y spun from the spinning machine 2. The first godet roller 6 is located on the lower side in the vertical direction of the spinning machine 2. The first godet roller 6 is installed in the housing 20 (see Figure 4). The first godet roller 6 rotates around a rotation axis that extends in the left-right direction. The first godet roller 6 is rotationally driven by a first godet motor (not shown).

[0034] The second godet roller 7 is positioned behind the first godet roller 6. The second godet roller 7 rotates around a rotation axis that extends in the left-right direction. The second godet roller 7 is rotationally driven by a second godet motor (not shown).

[0035] The second godet roller 7 is movably supported by a guide rail 8. The guide rail 8 is positioned diagonally to the front-to-back direction such that one end in the longitudinal direction (the left end in Figure 1) is at the bottom and the other end in the longitudinal direction (the right end in Figure 1) is at the top. The second godet roller 7 is connected to a cylinder (not shown). The second godet roller 7 moves along the guide rail 8 by the cylinder. This allows the second godet roller 7 to move between the winding position, shown by the solid line in Figure 1, and the thread-hanging position, shown by the dashed line in Figure 1. The winding position is the position when winding the thread Y. The thread-hanging position is a position located closer to the first godet roller 6 than the winding position, and is the position when threading.

[0036] The yarn regulating mechanism 9 is positioned above the first godet roller 6. As shown in Figures 3, 4, and 5, the yarn regulating mechanism 9 is installed on the side 20C of the housing 20. The yarn regulating mechanism 9 has a first regulating section 9A and a second regulating section 9B. The first regulating section 9A is positioned above the second regulating section 9B. The first regulating section 9A and the second regulating section 9B each define the spacing between the multiple yarns Y that are wound around the first godet roller 6. The first regulating section 9A and the second regulating section 9B stabilize the movement of the multiple yarns Y and restrict the left-right movement of the multiple yarns Y arranged in the left-right direction.

[0037] As shown in Figures 1 and 2, the winding unit 10 includes a plurality of pivot guides 11, a plurality of traverse guides 12, a turret 13, two bobbin holders 14, and a contact roller 15.

[0038] As shown in Figure 1, multiple support guides 11 are individually provided for multiple threads Y and are arranged in the front-to-back direction. The multiple support guides 11 are movably mounted on a guide member 16. The guide member 16 is positioned so that its longitudinal direction is aligned with the front-to-back direction. The guide member 16 is attached to the main frame 19 by a support member 18 attached to its lower side.

[0039] Multiple traverse guides 12 are individually provided for multiple threads Y and are arranged in a line in the front-to-back direction. Each traverse guide 12 is driven by a traverse motor (not shown) and moves back and forth in the front-to-back direction. The threads Y that are placed on the traverse guides 12 traverse around the pivot guide 11.

[0040] The turret 13 is a disc-shaped member. The turret 13 rotates around a rotation axis that extends in the front-rear direction. The turret 13 is rotationally driven by a turret motor (not shown). Each of the two bobbin holders 14 has an axial direction that extends in the front-rear direction. Each of the two bobbin holders 14 is rotatably supported at the upper and lower ends of the turret 13. Multiple bobbins B, each individually provided for multiple threads Y, are mounted in the front-rear direction on each bobbin holder 14. Each of the two bobbin holders 14 is rotationally driven by an individual winding motor (not shown).

[0041] In the winding unit 10, when the upper bobbin holder 14 is rotated, the thread Y traversed by the traverse guide 12 is wound onto the bobbin B to form the package P. After the formation of the package P is complete, the turret 13 is rotated to swap the upper and lower positions of the two bobbin holders 14. As a result, the bobbin holder 14 that was previously in the lower position moves to the upper position, and the thread Y can be wound onto the bobbin B attached to this bobbin holder 14 to form the package P. Also, the bobbin holder 14 that was previously in the upper position moves to the lower position, and the completed package P can be recovered from this bobbin holder 14.

[0042] The contact roller 15 is positioned above the upper bobbin holder 14. The contact roller 15 rotates around a rotation axis that extends in the front-rear direction. The contact roller 15 contacts the surface of the package P on which the yarn Y is wound, which is mounted on the bobbin B attached to the upper bobbin holder 14, thereby applying contact pressure to the surface of the package P during the winding of the yarn Y.

[0043] The yarn cutting device 4 operates after yarn winding is completed in the take-up device 3 or when yarn is cut, and holds multiple yarns Y. The yarn cutting device 4 is located above the yarn regulating mechanism 9. As shown in Figure 3, the yarn cutting device 4 is installed in the housing (member) 20.

[0044] As shown in Figure 6, the thread cutting device 4 includes a holder 40, a suction device 41, and a cutter 42. The holder 40 is the base of the thread cutting device 4 and is provided in the housing 20 (see Figure 4).

[0045] The suction device 41 sucks up multiple threads Y that have been cut by the cutter 42. The suction device 41 has a holding part 43, a suction part 44, and a cylinder 45. The holding part 43 and the suction part 44 are cylindrical members. The suction part 44 is held in relation to the holding part 43 so as to be able to move back and forth, and the inside of the holding part 43 and the inside of the suction part 44 are in communication. Airtightness is maintained between the outside of the suction part 44 and the inside of the holding part 43 so as not to leak air. A suction port 44A for sucking up the multiple cut threads Y is formed at the tip of the suction part 44. The holding part 43 is fixed to the holder 40 so as to be parallel to the direction of movement of the suction part 44 (left and right direction) of the multiple threads Y. The suction part 44 penetrates the inside of the holder 40, and the suction port 44A at the tip protrudes from the opening 40A of the holder 40.

[0046] A suction source 48 (see Figure 2) is connected to the suction device 41. The suction source 48 generates an airflow for suction. The suction source 48 generates a suction force at the suction port 44A that sucks in the multiple cut threads Y. The suction source 48 and the suction device 41 are connected via an electromagnetic valve (not shown).

[0047] The cylinder 45 is fixed to the holder 40. The cylinder 45 has a cylinder rod 46. The tip of the cylinder rod 46 is connected to a connecting member 47 fixed to the suction part 44. The cylinder 45 is driven by a drive device 49 (see Figure 2). As the cylinder 45 moves forward and backward by the drive device 49, the suction part 44 moves between a first position P1 (see Figure 7(C)) where it is advanced and a second position P2 (see Figure 7(A)) where it is retracted from the first position P1. As shown in Figures 3 and 4, the suction part 44 protrudes from the side 20C of the housing 20 at the first position P1.

[0048] As shown in Figure 6, the cutter 42 cuts multiple threads Y when the thread winding is completed or when the thread is cut in the take-up device 3. The cutter 42 moves back and forth together with the suction unit 44 of the suction device 41, and cuts multiple threads Y upstream of the thread restricting mechanism 9 when the suction unit 44 advances. Specifically, as shown in Figures 7(A), 7(B), and 7(C), the cutter 42 cuts the threads Y as the suction unit 44 moves from the second position P2 to the first position P1. At this time, the suction unit 44 sucks up the threads Y cut by the cutter 42. As shown in Figures 7(D) and 7(E), the cutter 42 moves back together with the suction unit 44, which has sucked up multiple threads Y, and moves from the first position P1 to the second position P2.

[0049] The cutter 42 continuously cuts one or more threads Y at a time, which are arranged along the direction of arrangement. Here, continuously cutting one or more threads Y at a time means gradually cutting multiple threads Y that are not bundled together. In other words, continuously cutting one or more threads Y at a time means that as the suction unit 44 moves from the second position P2 to the first position P1, the cutter 42 repeatedly contacts one or more threads Y as the suction unit 44 moves, cutting the multiple threads Y. Therefore, this is different from cutting a bundle of multiple threads Y in a single operation.

[0050] As shown in Figures 3, 4, and 5, the cutting unit 5 is used by an operator to cut multiple threads Y. The cutting unit 5 cuts the bundle of multiple threads Y before they are threaded onto the thread puller 3. As shown in Figure 8, the cutting unit 5 has a first blade (cutting blade) 50, a second blade (cutting blade) 51, a guide member 52, and a mounting member 54. The state of the cutting unit 5 shown in Figure 7 is considered the front view of the cutting unit 5.

[0051] The first blade 50 consists of a first blade portion 50A, which is its tip, and a first base portion 50B connected to the first blade portion 50A. The second blade 51 consists of a second blade portion 51A, which is its tip, and a second base portion 51B connected to the second blade portion 51A.

[0052] The first blade 50 and the second blade 51 are positioned with their first base 50B and second base 51B overlapping, with the first blade 50 on the upper side and the second blade 51 on the lower side. The first ridge 50R of the cutting edge of the first blade 50 and the second ridge 51R of the cutting edge of the second blade 51 intersect at their midpoint. As a result, an intersection C is formed in the cutting section 5 where the first blade 50 and the second blade 51 intersect. The first blade 50 has a cutting angle θ1 of the first cutting portion 50A that is 15 degrees or more and less than 30 degrees. The second blade 51 has a cutting angle θ2 of the second cutting portion 51A that is 15 degrees or more and less than 30 degrees. In this embodiment, the cutting angle θ1 of the first blade 50 and the cutting angle θ2 of the second blade 51 are equal. A gap is provided between the first cutting portion 50A of the first blade 50 and the second cutting portion 51A of the second blade 51. In other words, a portion of the lower surface of the first blade portion 50A and a portion of the upper surface of the second blade portion 51A face each other with a gap between them.

[0053] The guide member 52 is positioned on top of the first blade 50 on the far side of the paper in Figure 8. The guide member 52 is for guiding multiple threads Y to the intersection C where the first blade portion 50A and the second blade portion 51A formed on the first blade 50 and the second blade 51 intersect. The guide member 52 is formed in a substantially V shape to guide the multiple threads Y to the intersection C where the first blade 50 and the second blade 51 intersect.

[0054] As shown in Figures 3, 4, and 5, the mounting member 54 attaches the first blade 50 and the second blade 51 to the housing 20. The mounting member 54 has a fixing portion 54A, an extended portion 54B, and a support portion 54C. The fixing portion 54A, the extended portion 54B, and the support portion 54C are integrally molded. The mounting member 54 has, for example, a roughly L-shape. The mounting member 54 is formed by bending a metal plate-like member. The thickness (plate thickness) of the mounting member 54 is, for example, 6 mm. The mounting member 54 has sufficient strength to withstand the load (load) applied to the cutting portion 5 during the cutting operation of multiple threads Y by the worker.

[0055] The fixing portion 54A is the part that is fixed to the 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, etc.

[0056] The extended portion 54B is connected to the fixed portion 54A and extends in the left-right direction. The extended portion 54B is connected to the front end of the fixed portion 54A. The support portion 54C is connected to the extended portion 54B and extends in the up-down direction. The support portion 54C is connected to the right end of the extended portion 54B. The support portion 54C is connected to the lower part of the first blade 50 and the second blade 51 and supports the first blade 50 and the second blade 51. When viewed from the left-right direction, the extended portion 54B and the support portion 54C are located in front of the intersection C between the first blade portion 50A and the second blade portion 51A. That is, when viewed from the left-right direction, the extended portion 54B and the support portion 54C do not have any portions located behind the intersection C.

[0057] The cutting unit 5 is fixed to the housing 20 of the take-up device 3. The cutting unit 5 is fixed to the housing 20 in which the yarn cutting device 4 is installed. In other words, the yarn cutting device 4 and the cutting unit 5 are fixed to the same component. In this embodiment, the cutting unit 5 is installed in the housing 20 of each take-up device 3 of a plurality of spinning take-up machines 1.

[0058] The housing 20 is provided at one end of the guide rail 8 in the longitudinal direction. The housing 20 has a front part (other side part) 20A on which the operating part (first operating part) 22 is provided, a rear part 20B facing the winding part 10, and a pair of side parts 20C, 20D connecting the front part 20A and the rear part 20B. The pair of side parts 20C, 20D face each other in the left-right direction. The side surface 20S of side part 20C is perpendicular to the left-right direction (arrangement direction). A waste yarn pipe 21 for discharging waste yarn is provided on side part 20D.

[0059] The front section 20A is positioned facing the work area A. The work area A is the area where the operator is positioned during the cutting operation. As shown in Figure 9, the work area A is located in the front (one side) of the suction section 44 of the yarn cutting device 4 in the front-to-back direction (orthogonal direction) which is perpendicular to the arrangement direction (left-to-right direction) of the multiple yarns Y in the horizontal plane. The work area A is the area (space) on the passage T provided in front of the housing 20. In this embodiment, as shown in Figure 2, the spinning take-up machines 1 are installed side by side in the left-to-right direction (arrangement direction), and the passage T through which the operator passes also extends in the left-to-right direction. The direction of extension of the passage T is perpendicular (intersects) to the side surface 20S of the side section 20C of the housing 20. The work area A is provided on the passage T that extends along the left-to-right direction. In this embodiment, the front section 20A of the housing 20 faces the passage T side. Therefore, the operation section 22 provided on the front section 20A of the housing 20 can be operated in the work area A. Note that in Figure 9, for the sake of explanation, work area A is shown as a rectangle with a dashed line, but this does not mean that the shape of work area A is rectangular.

[0060] As shown in Figures 3, 4, and 5, the cutting section 5 is fixed to the side (one side) 20C of the housing 20. The cutting section 5 is positioned such that the cutting portions of the multiple threads Y in the cutting section 5, i.e., the intersection C of the first blade 50 and the second blade 51, are spaced apart from the side 20C by the mounting member 54.

[0061] The cutting section 5 is positioned near the suction port 44A of the suction section 44 located at the first position P1 (see Figure 7(C)). Nearby means, for example, a distance of 100 mm or less from the suction port 44A. Specifically, this is the distance in the front-rear direction between the suction port 44A and the upper end of the guide member 52 of the cutting section 5. In this embodiment, the distance in the front-rear direction between the suction port 44A and the upper end of the guide member 52 of the cutting section 5 is, for example, about 80 mm.

[0062] The cutting section 5 is positioned so that its front faces the work area A. The cutting section 5 is positioned so that when the worker is in the work area A, the intersection C of the first blade 50 and the second blade 51 is visible to the worker. Specifically, the cutting section 5 is positioned so that the overlapping direction of the first blade 50 and the second blade 51 is perpendicular to the left-right direction, and the intersection C is visible when viewed from front to back in the front-back direction. The cutting section 5 cuts multiple threads Y that enter the intersection C from above. The direction in which the multiple threads Y enter the cutting section 5 is vertical.

[0063] The intersection C of the first blade 50 and the second blade 51 of the cutting section 5 is located above the suction section 44 in the vertical direction. As shown in Figure 4, the cutting section 5 is located further from the side portion 20C in the left-right direction than the tip (suction port 44A) of the suction section 44 located at the first position P1 in the thread cutting processing device 4.

[0064] As shown in Figure 5, when viewed from the left and right directions, the first blade 50, the second blade 51, and the guide member 52 of the cutting section 5 are positioned at an angle. Specifically, when viewed from the left and right directions, the upper parts of the first blade 50, the second blade 51, and the guide member 52 are positioned towards the rear, and the lower parts of the first blade 50, the second blade 51, and the guide member 52 are positioned towards the front. In other words, the upper parts of the first blade 50, the second blade 51, and the guide member 52 are tilted away from the work area A. When viewed from the left and right directions, the distance in the front-to-back direction between the lower part of the first blade 50, the second blade 51, and the guide member 52 and the position of the suction section 44 is shorter than the distance in the front-to-back direction between the upper part of the first blade 50, the second blade 51, and the guide member 52 and the position of the suction section 44.

[0065] The first blade 50, the second blade 51, and the guide member 52 are inclined, for example, in a range greater than 0° and less than 90° with respect to the vertical direction. 0° is when the first blade 50, the second blade 51, and the guide member 52 are aligned in the vertical direction, and 90° is when they are aligned in the front-rear direction. In this embodiment, the inclination angle θ is, for example, 35°.

[0066] Next, the electrical configuration of the spinning take-up machine 1 will be described. The spinning take-up machine 1 is equipped with a control device 23. The control device 23 is a processor with an integrated circuit implemented on it or a computer system equipped with one. The control device 23 is the part that controls various operations in the spinning take-up machine 1 and consists of a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), and input / output interfaces.

[0067] The control device 23 controls the first godet motor that drives the first godet roller 6, the second godet motor that drives the second godet roller 7, and the cylinder. This drives the first godet roller 6 and the second godet roller 7. The control device 23 controls the electromagnetic valve (not shown) provided in the suction device 41. This drives the electromagnetic valve to open and close. The control device 23 controls the drive device 49. This drives the cylinder 45 of the suction device 41, causing the cylinder rod 46 attached to the cylinder 45 to move back and forth, thereby causing the suction unit 44 connected to it to move back and forth in the left and right directions. 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, turret 13, bobbin holder 14, etc., provided in the winding unit 10.

[0068] Next, we will explain how to load multiple yarns Y spun from the spinning device 2 onto the take-up device 3 in the spinning take-up machine 1. Here, we will explain the case where yarn loading is performed simultaneously in multiple spinning take-up machines 1 in the melt spinning equipment 100.

[0069] First, a method for temporarily holding multiple yarns Y spun from the spinning machine 2 in the yarn cutting device 4 will be described. The operator acquires the multiple yarns Y spun from the spinning machine 2 below the spinning machine 2 (work area A). Next, the operator grasps the multiple yarns Y with both hands and bundles them together so that the cutting section 5 is positioned between one hand and the other hand in the front-to-back direction, and inserts the bundle of yarns Y between the two hands into the cutting section 5. Then, the operator pushes down the bundle of yarns Y at the cutting section 5, cutting the bundle of yarns Y all at once. Specifically, the operator pushes down the bundle of yarns Y by moving the hand on the back side downwards while keeping the height position of the hand on the front side fixed. After cutting, the operator brings the multiple yarns Y to the suction port 44A of the suction section 44 of the yarn cutting device 4 and sucks them up from the suction port 44A. As a result, the multiple yarns Y with their ends cut are held in the yarn cutting device 4. The operator also uses the same method to temporarily hold multiple yarns Y in the yarn cutting device 4 at other spinning draw machines 1.

[0070] The method for cutting the multiple threads Y at the cutting section 5 is not limited to the method described above, and they may be cut by other methods. The worker can simply apply tension to the multiple threads Y to cut them.

[0071] Next, a method for threading the multiple threads Y held in the thread cutting device 4 onto the thread taking device 3 will be described. The operator cuts the multiple threads Y held in the thread cutting device 4 with scissors and sucks the multiple threads Y spun from the spinning device 2 into the suction gun 110. The operator sets the multiple threads Y sucked up by the suction gun 110 into the thread regulating mechanism 9 and winds them onto the first godet roller 6 and the second godet roller 7 in that order. At this time, the second godet roller 7 is positioned in the thread threading position. After that, the multiple threads Y are set into the winding unit 10 according to a predetermined procedure.

[0072] As described above, the melt spinning equipment 100 according to this embodiment is equipped with a cutting unit 5 used for cutting multiple yarns Y by an operator. Specifically, the melt spinning equipment 100 is equipped with a dedicated cutting unit 5 for cutting bundles of multiple yarns Y before they are threaded onto the take-up device 3 when threading multiple yarns Y spun from the spinning device 2 onto the take-up device 3. This allows the operator to cut bundles of multiple yarns Y all at once using the cutting unit 5 without using cutting tools or cutters. Therefore, when multiple spinning take-up machines 1 are installed, it is possible to improve work efficiency and safety when threading multiple yarns spun from the spinning device 2 onto the take-up device 3, and to prevent malfunctions in the cutter of the yarn cutting device.

[0073] In the melt spinning apparatus 100 according to this embodiment, the suction unit 44 of the yarn cutting device 4 holds a plurality of yarns Y that have been cut in the cutting unit 5. Therefore, even if 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.

[0074] In the melt spinning equipment 100 according to this embodiment, the cutting section 5 is installed in the take-up device 3 of each of the multiple spinning take-up machines 1. With this configuration, multiple yarns Y can be cut at the cutting section 5 installed in the take-up device 3 of each spinning take-up machine 1, thereby further improving work efficiency.

[0075] The melt spinning equipment 100 according to this embodiment is equipped with multiple suction guns 110 capable of sucking up multiple yarns Y spun from the spinning device 2. The number of suction guns 110 installed is less than the number of spinning take-up machines 1 installed. In this configuration, when yarn threading occurs at the same time in multiple spinning take-up machines 1, if yarn threading is being performed in one spinning take-up machine 1, the suction guns 110 may not be able to receive the yarn Y spun from the spinning device 2 in the other spinning take-up machines 1. Therefore, in a configuration where the number of suction guns 110 installed is less than the number of spinning take-up machines 1 installed, the multiple yarns Y cut in the cutting section 5 are held in the suction section 44 of the yarn cutting processing device 4 in each spinning take-up machine 1, thereby eliminating waiting time for using the suction guns 110 and improving work efficiency.

[0076] In the melt spinning apparatus 100 according to this embodiment, the cutting unit 5 is located near the suction port 44A of the suction unit 44 of the yarn cutting apparatus 4. In this embodiment, the suction unit 44 of the yarn cutting apparatus 4 is provided to be movable in the left-right direction between a first position P1 to which it advances and a second position P2 to which it retracts from the first position P1. The cutting unit 5 is located near the suction port 44A of the suction unit 44 located at the first position P1. With this configuration, the multiple yarns Y cut in the cutting unit 5 can be easily guided to the suction port 44A of the suction unit 44.

[0077] In the melt spinning apparatus 100 according to this embodiment, the yarn cutting apparatus 4 and the cutting unit 5 are fixed to the side portion 20C of the housing 20 in the take-up device 3. With this configuration, the multiple yarns Y cut in the cutting unit 5 can be easily guided to the suction port 44A of the suction unit 44.

[0078] In the melt spinning apparatus 100 according to this embodiment, a work area A is provided in front of the suction section 44 of the yarn cutting apparatus 4 in the front-to-back direction, where the operator is positioned during the cutting operation, and a cutting section 5 is provided behind the suction section 44. In this configuration, since the work area A and the cutting section 5 face each other in the front-to-back direction, the cutting section does not get in the way when the yarn is being fed by the suction gun 110.

[0079] In the melt spinning apparatus 100 according to this embodiment, the cutting unit 5 is positioned so that, when viewed from front to back in the front-to-back direction, it is further from the side surface 20S in the left-to-right direction than the suction port 44A of the suction unit 44 of the yarn cutting processing apparatus 4. In this configuration, when an operator is working in the work area A, the suction unit 44 does not get in the way when guiding the multiple yarns Y cut in the cutting unit 5 to the suction port 44A of the suction unit 44. Therefore, the multiple yarns cut in the cutting unit 5 can be easily guided to the suction port 44A of the suction unit 44.

[0080] In the melt spinning apparatus 100 according to this embodiment, the cutting section 5 comprises a first blade 50 having a first blade portion 50A, and a second blade 51 positioned on top of the first blade 50 and having a second blade portion 51A. When viewed from the overlapping direction in which the first blade 50 and the second blade 51 overlap, the first ridge line 50R of the cutting edge of the first blade portion 50A and the second ridge line 51R of the cutting edge of the second blade portion 51A intersect, forming an intersection C where the first blade portion 50A and the second blade portion 51A intersect. In the melt spinning apparatus 100, a work area A is provided on the front side of the suction section 44 in the front-rear direction, where the operator is positioned when performing the cutting work. In the melt spinning apparatus 100, the cutting section 5 is fixed to the side portion 20C of the housing 20 such that the left-right direction and the overlapping direction of the cutting section 5 are perpendicular, and the intersection C is visible when viewed from front to back in the front-rear direction.

[0081] In the melt spinning apparatus 100 according to this embodiment, the intersection C where the first blade 50 and the second blade 51 intersect is located above the suction section 44 in the vertical direction. With this configuration, the multiple threads Y cut by the first blade 50 and the second blade 51 of the cutting section 5 can be easily guided to the suction port 44A of the suction section 44.

[0082] In the melt spinning apparatus 100 according to this embodiment, the cutting section 5 cuts multiple threads Y that enter the intersection C from above. In this configuration, the operator can cut multiple threads Y by moving them from top to bottom in front of the cutting section 5. Therefore, multiple threads Y can be easily cut.

[0083] In the melt spinning apparatus 100 according to this embodiment, the first blade 50 and the second blade 51 are inclined such that, when viewed from the left and right directions, the upper parts of the first blade 50 and the second blade 51 are located on the rear side in the front-to-back direction, and the lower parts of the first blade 50 and the second blade 51 are located on the front side in the front-to-back direction. When performing the cutting operation, the operator grasps multiple threads Y with both hands, bundles the multiple threads Y together, inserts the bundle of threads Y into the cutting section 5 between one hand and the other, and moves the multiple threads Y from top to bottom. At this time, while keeping the height position of the hand on the front side fixed, the operator pushes down the bundle of threads Y by moving the hand on the rear side downwards. When performing such an operation, if the first blade 50 and the second blade 51 are inclined as described above, it becomes easier to apply a shearing force to the multiple threads Y, so that the multiple threads Y can be easily cut.

[0084] In the melt spinning apparatus 100 according to this embodiment, the cutting section 5 has a mounting member 54 for attaching the first blade 50 and the second 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 extending portion 54B connected to the fixing portion 54A and extending in the left-right direction, and a support portion 54C connected to the extending portion 54B and extending in the up-down direction, and connected to the lower part of the holding member 53 to support the holding member 53. In this configuration, the extending portion 54B extends in the left-right direction, and the support portion 54C connected to the extending portion 54B extends in the up-down direction. By configuring the apparatus so that the extending portion 54B and the support portion 54C do not have any parts that protrude in the front-rear direction when viewed from the left-right direction, it is possible to prevent the mounting member 54 from getting in the way during cutting work or multiple threads Y from getting caught on the mounting member 54. Furthermore, in a configuration in which the fixing part 54A is fixed to the side part 20C, when the cutting part 5 is positioned near the suction port 44A of the suction part 44, it is not necessary to lengthen the extended part 54B. This ensures that the mounting member 54 has sufficient strength to withstand the load applied to the cutting part 5 during the cutting operation.

[0085] In the melt spinning equipment 100 according to this embodiment, the housing 20 is provided with an operating unit 22 for operation by an operator. The operating unit 22 is located on the front part 20A of the housing 20, which is different from the side part 20C to which the cutting unit 5 is fixed. The work area A, where the operator is positioned during the cutting operation, is located in a position from which the operating unit 22 can be operated. With this configuration, the cutting operation of the yarn Y and the operation of the operating unit 22 can be performed in the work area A. Therefore, the work area A can be effectively utilized in a limited space such as a factory where the melt spinning equipment 100 is installed.

[0086] In the melt spinning equipment 100 according to this embodiment, a plurality of spinning take-up machines 1 are arranged along the left-right direction. The melt spinning equipment 100 is provided with a passage T through which workers pass, extending along the left-right direction. The work area A where workers are positioned during cutting operations is located on the passage T. In this configuration, since the passage T is provided in a straight line extending along the left-right direction, workers can move easily. In addition, since the cutting section is not located on the passage T, workers passing through the passage T can avoid coming into contact with the cutting section.

[0087] While embodiments of the present invention have been described above, the present invention is not necessarily limited to the embodiments described above, and various modifications are possible without departing from the spirit of the invention.

[0088] In the above embodiment, one example described was a configuration in which the cutting section 5 is located on the side 20C of the housing 20, on the rear side relative to the suction section 44. However, the cutting section 5 may also be located on the front side (work area A side) relative to the suction section 44.

[0089] In the above embodiment, a configuration in which the cutting section 5 has a first blade 50, a second blade 51, a guide member 52, and a mounting member 54 was described as an example. However, the cutting section may have any configuration as long as it can cut a bundle of multiple threads Y at once.

[0090] In the above embodiment, an example was described in which the cutting unit 5 is installed on the side portion 20C of the housing 20, i.e., on the take-up device 3. However, the cutting unit 5 may also be installed on the yarn cutting processing device 4. Furthermore, the cutting unit 5 may be installed on both the take-up device 3 and the yarn cutting processing device 4. Multiple cutting units 5 may be installed on both the take-up device 3 and the yarn cutting processing device 4.

[0091] In the above embodiment, a configuration in which the fixing portion 54A of the mounting member 54 is fixed to the side portion 20C of the housing 20 was described as an example. However, the fixing portion 54A may also be fixed to, for example, the upper part of the housing 20.

[0092] In the above embodiment, a configuration in which the cutting portion 5 is fixed to the side portion 20C of the housing 20 by a mounting member 54 was described as an example. However, the cutting portion 5 may also be configured to be housed inside the housing 20 when not in use and to extend out of the housing 20 when in use.

[0093] In the above embodiment, a configuration in which the cutting section 5 is positioned so that its front faces the work area A was described as an example. However, the orientation of the cutting section 5 is not limited to this.

[0094] In the above embodiment, a configuration in which the yarn cutting device 4 has one cutter 42 was described as an example. However, the yarn cutting device 4 may have two or more cutters.

[0095] In the above embodiment, a configuration in which the cutter 42 moves together with the suction unit 44 to cut the thread Y in the thread cutting device 4 was described as one example. However, the cutter may be fixed in the thread cutting device. In this configuration, for example, a guide mechanism is provided to guide multiple threads to the cutter, and the cutter cuts the multiple threads that have been guided to the cutter by the guide mechanism. The guide mechanism moves the multiple threads along the arrangement direction to guide the multiple threads to the cutter. The guide mechanism may, for example, hook the multiple threads with a hook and guide them to the cutter, or it may move a defining part that defines the spacing between the multiple threads Y in the arrangement direction to guide the multiple threads to the cutter. Alternatively, the thread cutting device may be provided with a guide mechanism that guides multiple threads to the cutter, and the guide mechanism guides the multiple threads to the cutter, while the cutter moves relative to the guide mechanism to cut the multiple threads.

[0096] In the above embodiment, a configuration in which each of the multiple spinning take-up machines 1 is provided with a cutting section 5 was described as an example. However, one cutting section 5 may be provided for multiple spinning take-up machines 1. For example, as shown in Figure 10, in adjacent spinning take-up machines 1, the cutting section 5 may be provided only in one spinning take-up machine 1 (left side in the figure), and the cutting section 5 may not be provided in the other spinning take-up machine 1 (right side in the figure). In the example shown in Figure 10, in adjacent spinning take-up machines 1, the yarn cutting processing device 4, etc., are arranged in the housing 20 so that they face each other.

[0097] In the other spinning take-up machine 1, when multiple yarns Y spun from the spinning device 2 are to be temporarily held in the yarn cutting device 4, the multiple yarns Y are cut by the cutting section 5 provided in one of the spinning take-up machines 1. After cutting, the operator takes the multiple yarns Y to the suction port 44A of the suction section 44 of the yarn cutting device 4 in the other spinning take-up machine 1 and allows them to be sucked in from the suction port 44A.

[0098] In the above embodiment, as shown in Figure 2, the spinning take-up machines 1 are arranged side by side in the left-right direction, and a work area A is provided on a passage T that extends along the direction of arrangement of the spinning take-up machines 1. However, the work area A can be set appropriately according to the arrangement of the spinning take-up machines 1. For example, as shown in Figure 11(A), in a configuration where multiple spinning take-up machines 1 are arranged with their positions offset in the front-rear direction, the work area A can be provided in front of the housing 20 of the take-up device 3 of each spinning take-up machine 1. For example, as shown in Figure 11(B), in a configuration where multiple spinning take-up machines 1 are arranged on a circular orbit, the work area A can be provided in front of the housing 20 of the take-up device 3 of each spinning take-up machine 1 (towards the center of the circle). For example, as shown in Figure 11(C), in a configuration where multiple spinning take-up machines 1 are arranged facing each other, the work area A can be provided between the opposing spinning take-up machines 1.

[0099] In addition to the above embodiment, the winding unit 10 may also include an operating unit (second operating unit) operated by an operator. In this configuration, the operating unit 22 provided on the housing 20 and the operating unit provided on the winding unit 10 may be positioned to face the same direction (the front side in the front-rear direction). In this configuration, the operator can operate the operating unit while visually checking (inspecting) both the operating unit 22 provided on the housing 20 and the operating unit provided on the winding unit 10.
