Summary of the Invention

Problems to be Solved by the Invention

[0005] However, according to the technique described in Patent Document 1, since the forward and reverse rotation of the motor is controlled by a control device, not only does the lightweight oil supply discharge nozzle device as an oil agent application device become a large-scale device, but there is also a possibility of being expensive in terms of cost.

[0006] The present invention has been made in view of the above problems, and aims to provide a spinning apparatus that can suitably raise and lower an oil application device with a simple configuration. [Means for solving the problem]

[0007] (1) The spinning equipment of the present invention is A spinning device that spins yarn downwards from each of multiple die heads, An oiling device is positioned below the spinning apparatus and includes a plurality of oiling guides for applying oil to each of the plurality of threads spun from the plurality of die heads, A support member that supports the plurality of fueling guides, The spinning apparatus is equipped with a lifting device for raising and lowering the oil application device, The aforementioned lifting device is The support member is connected at least at two locations, and at least two wires support the support member from above, Includes an operating unit for raising and lowering the support member connected to the at least two wires. It is characterized by the following:

[0008] According to the spinning equipment described in (1) above, the oil application device can be raised and lowered with a simple configuration that only involves raising and lowering the wire connected to the support member. Moreover, since the support member is connected to the wire at least at two points, multiple oil supply guides can be raised and lowered in a more balanced manner compared to the case where the support member and the wire are connected at only one point.

[0009] (2) In the spinning equipment of the present invention, The aforementioned lifting device is A winding member that winds up part or all of the two wires by rotation to raise and lower the support member connected to the wires, The locking mechanism further includes a locking mechanism for locking the rotation of the winding member. It would be preferable to do so.

[0010] The spinning equipment described in (2) above is preferable because the wire can be stopped at any position. In particular, there are cases where it is desired to raise or lower the oil dispenser not only when changing the yarn type, but also without changing the yarn type. In such cases, the range of raising or lowering the oil dispenser is smaller compared to when changing the yarn type. In this respect, the above configuration allows the wire to be stopped at any position, so it can also accommodate cases where it is desired to raise or lower the oil dispenser only slightly.

[0011] (3) In the spinning apparatus of the present invention, The aforementioned operating unit is The winding member is capable of being rotated and is configured to be operated at a position within a 1m distance forward from the oil application device. It would be preferable to do so.

[0012] The spinning equipment described in (3) above is preferable because the control unit can be operated at a distance from the oil dispenser, and the operator can operate the control unit while checking the vertical movement of the oil dispenser. Therefore, the oil dispenser can be raised and lowered even while the spinning equipment is in operation without stopping the spinning equipment. Note that the "location within a range of 1m in front" can be any location where the operator can operate the control unit while checking the vertical movement of the oil dispenser.

[0013] (4) In the spinning equipment of the present invention, The locking mechanism is a worm gear having a worm and a worm wheel, The aforementioned operating unit is The rod-shaped member connected to the worm is configured to rotate, having the same axial direction as the worm. The aforementioned winding member is It is configured to rotate coaxially with the worm wheel. It would be preferable to do so.

[0014] According to the spinning equipment described in (4) above, it is more preferable because when the operating part is operated to rotate the rod-shaped member, the worm rotates. By doing so, when the worm rotates, the worm wheel rotates, and the winding member coaxial with the worm wheel rotates, and the wire can be lifted and lowered. With such a simple configuration, the oil application device can be lifted and lowered. Moreover, by using the rod-shaped member, the operating part can be operated at a position away from the oil application device, and the oil application device can be lifted and lowered even when the spinning equipment is in operation.

[0015] (5) In the spinning equipment of the present invention, The support member has a first connection part to which one wire of at least two wires is connected, and a second connection part to which another wire different from the one wire is connected. The lifting device is A first sheave that winds around the one wire connected to the first connection part and applies tension to the one wire, A second sheave that winds around the other wire connected to the second connection part and applies tension to the other wire, And a tension adjusting device that changes the position of at least one of the first sheave and the second sheave. It is more preferable to do so.

[0016] According to the spinning equipment described in (5) above, by changing the position of at least one of the first sheave and the second sheave, the tension of at least one of the one wire and the other wire can be changed, so it is more preferable. By doing so, the height position in the left-right direction of the support member that supports the plurality of oil supply guides can be adjusted, and the distance from the die to the oil supply guides can be made substantially the same without causing a bias among the plurality of oil supply guides arranged in the left-right direction.

[0017] (6) In the spinning equipment of the present invention, The support member has a first connection part to which one wire of at least two wires is connected, and a second connection part to which another wire different from the one wire is connected. The lifting device is provided between the first connecting portion and the winding member, and the one wire The first outer part is inserted into the interior. member provided between the second connecting portion and the winding member, and the other wire The second outer part is inserted into the interior. member, and further includes is more preferably made as follows.

[0018] According to the spinning equipment described in (6) above, it is possible to lift the size application device with a simple structure having a small number of parts, not only reducing the cost but also suppressing damage to the members constituting the size application device. Further, the one wire and the other wire are respectively inserted into the first outer side member and the second outer side member of inside department inserted Enter Thereby, even when there is a limitation in the installation location as in the case of providing a lifting device in an existing spinning equipment, the lifting device can be easily provided in the spinning equipment.

[0019] (7) In the spinning equipment of the present invention, the first outer side member and the second outer side [[ID=3,5]]member are respectively provided such that the one wire and the other wire are connected to the support member in a substantially vertical direction. is more preferably made as follows.

[0020] According to the spinning equipment described in (7) above, since the one wire and the other wire are connected to the support member in a substantially vertical direction, the size application device can be smoothly lifted and lowered via the support member. In particular, when lifting the size application device, the dispersion of the force for lifting the size application device can be suppressed, and the size application device can be efficiently lifted.

[0021] (8) In the spinning equipment of the present invention, further includes a tension adjusting device capable of changing the tension of at least one of the one wire and the other wire It would be preferable to do so.

[0022] The spinning equipment described in (8) above is preferable because, by changing the tension of at least one of the two wires, the tension of at least one of the two wires can be changed. This makes it possible to raise and lower the oil dispenser with a simple structure, while making the distance from the nozzle to the oil dispenser guide approximately the same among the multiple oil dispenser guides arranged in the left-right direction without any bias.

[0023] (9) In the spinning apparatus of the present invention, The aforementioned multiple fueling guides are arranged in a regular pattern in one direction when viewed from a specific direction. The support member is capable of supporting the plurality of lubrication guides which are regularly arranged in a line in the one direction. The aforementioned at least two wires are The support member is supported in such a way that there is no imbalance in the weight distribution in the aforementioned direction. It would be preferable to do so.

[0024] The spinning apparatus described in (9) above is more preferable because the support member that supports the multiple lubrication guides is supported by at least two wires so as not to cause an imbalance in weight distribution in one direction. In this way, the distance from the die to the lubrication guide can be made approximately the same among the multiple lubrication guides arranged in the left-right direction without any imbalance.

[0025] It should be noted that the spinning equipment according to the present invention is not required to include all of the configurations described in (1) to (9) above. For example, in the invention relating to the spinning equipment described in (1) above, the configurations described in (2) to (9) above are not required. Furthermore, within the scope of what can be made compatible, a spinning equipment according to the present invention can be made by arbitrarily combining the configuration described in (1) above with some or all of the configurations described in (2) to (9) above. For example, a spinning equipment according to the present invention can be made by combining the configuration described in (1) above with the configuration described in (2) above, or by combining the configuration described in (1) above, the configuration described in (2) above, and the configuration described in (6) above. However, a combination of the configuration described in (5) above with any of the configurations described in (6) to (8) above exceeds the scope of what can be made compatible, and therefore such a combination cannot be made into a spinning equipment according to the present invention. [Effects of the Invention]

[0026] According to the present invention, it is possible to provide a spinning apparatus that can suitably raise and lower an oil application device with a simple configuration. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0028] Embodiments of the present invention will be described below with reference to the drawings. For the sake of explanation, the vertical, horizontal, and front-to-back directions are as shown in the respective figures described later.

[0029] [1. Overview of Spinning Equipment] First, an overview of the spinning equipment 1 according to an embodiment of the present invention will be described with reference to Figure 1. Figure 1 is an example of a schematic diagram of the spinning equipment 1. The spinning equipment 1 according to an embodiment of the present invention is equipment for producing yarn Y made of synthetic fibers. The spinning equipment 1 comprises a spinning device 2, a cooling device 3, a slow cooling section (not shown), and an oiling device 10.

[0030] The spinning apparatus 2 is a melt spinning apparatus configured to spin a plurality of yarns Y made of molten polymer, and comprises a heating box 6 in a substantially rectangular parallelepiped shape and a plurality of spinning packs 7 each mounted in a plurality of pack housings formed in the heating box 6.

[0031] Multiple spinning packs 7 are arranged in a staggered pattern along the left-right direction, that is, alternately offset in the front-back direction (not shown). High-temperature liquid molten polymer (yarn material) is supplied to each spinning pack 7 from piping (not shown). A die 8 is positioned at the lower end of each spinning pack 7. Each of the multiple die 8 has, for example, multiple nozzles (not shown). The spinning pack 7 extrudes the yarn material from each of the multiple nozzles of the die 8. The yarn material extruded from each of the multiple nozzles is cooled by a cooling device 3 to become a single yarn Y consisting of multiple filaments f. That is, one yarn Y is spun from one die 8. Note that it is not necessary for each die 8 to have multiple nozzles; it may have only one nozzle. In this case, the yarn Y is produced as a monofilament yarn.

[0032] The cooling device 3 is located below the spinning apparatus 2 and cools and solidifies the yarn material discharged from the multiple die heads 8 using cooling air. The cooling device 3 is configured to be movable up and down by, for example, an air cylinder (not shown). When the operation of the spinning apparatus 1 is stopped and work is performed on, for example, the die heads 8, the cooling device 3 is lowered by, for example, an air cylinder (not shown).

[0033] Although the slow cooling section is not shown in the diagram, it is located vertically between the spinning apparatus 2 and the cooling device 3. The slow cooling section is configured to gradually cool (slowly cool) the yarn material before it is cooled by the cooling device 3 after it has been extruded from the spinning apparatus 2.

[0034] The oiling device 10 is located below the cooling device 3 and includes an oiling device 20 (see Figure 2, described later) which contains multiple oiling guides 22 for applying oil to multiple yarns Y spun from multiple die heads 8. In this embodiment, the oiling device 20 is configured to be raised and lowered relative to the spinning device 2.

[0035] [2. Detailed Configuration of the Lubricant Dispenser] Next, the detailed configuration of the lubricant dispenser 10 will be described. Figure 2 is a schematic diagram showing an example of a front view of the lubricant dispenser 10. Figure 3 is a schematic diagram showing an example of a right side view of the lubricant dispenser 10. Figure 4 is a schematic diagram showing an example of a rear view of the lubricant dispenser 10.

[0036] In this specification, when referring to the left and right directions with reference to Figure 4, the direction in the front view is used as the basis. That is, since Figure 4 is a rear view, even if it is the left direction on the page of Figure 4, it will be described as the right direction, and even if it is the right direction on the page of Figure 4, it will be described as the left direction.

[0037] As shown in Figures 2 to 4, the oil dispenser 10 mainly comprises a base member 12 made of a rectangular plate-shaped member, an oil dispenser 20, support members 14L and 14R that support the oil dispenser 20, and a lifting device 30 that raises and lowers the support members 14L and 14R relative to the base member 12. If the positional relationship between the spinning machine 2 and the base member 12 does not change, the oil dispenser 20 supported by the support members 14L and 14R can be raised and lowered relative to the spinning machine 2 by raising and lowering the support members 14L and 14R relative to the base member 12.

[0038] Support member 14L is a member provided in accordance with the rail 32L, which will be described later. Support member 14R is a member provided in accordance with the rail 32R, which will be described later.

[0039] [2-1. Oil dispenser] The oil dispenser 20 is supported by support members 14L and 14R in front of the base member 12, and comprises a plurality of (for example, 32 in this embodiment) oil supply guides 22, a plurality of (for example, 32 in this embodiment) oil supply pipes 24 corresponding to each of the plurality of oil supply guides 22, and a plurality of (for example, 32 in this embodiment) thread regulating guides 26. Furthermore, the oil dispenser 20 also comprises a plurality of (for example, 32 in this embodiment) support rods 23 that support each oil supply guide 22, a support bracket 25 that supports the plurality of support rods 23 with the left-right direction as the longitudinal direction, an oil droplet collection holder and an oil droplet collection holder support bracket (neither of which are shown), etc.

[0040] Multiple lubrication guides 22 are positioned directly below the cooling device 3 (see Figure 1). Each of the multiple lubrication guides 22 corresponds one-to-one with each of the multiple spinning packs 7 (see Figure 1). Each of the multiple lubrication guides 22 applies lubricant to the yarn Y spun downward from the corresponding spinning pack 7 (see Figure 1). The multiple lubrication guides 22 are regularly arranged in a single row horizontally when viewed from the front, and offset horizontally when viewed from above.

[0041] Multiple fuel supply pipes 24 are each connected to a fuel supply guide 22 via a support rod 23. The fuel supply pipes 24 are, for example, made up of hoses and can supply oil to the corresponding fuel supply guide 22 via the support rod 23.

[0042] Each of the multiple yarn regulating guides 26 is for defining the yarn path of the yarn Y to which oil has been applied by the multiple lubrication guides 22, and each of the multiple lubrication guides 22 corresponds to one of the multiple lubrication guides 26 on a one-to-one basis. The multiple yarn regulating guides 26, like the multiple lubrication guides 22, are arranged in a regular pattern, in a single row horizontally when viewed from the front, and offset horizontally when viewed from above in a plan view.

[0043] [2-2. Support Members] Support members 14L and 14R primarily support the support bracket 25 and the multiple thread regulating guides 26. As described above, the support bracket 25 supports the support rod 23, and via this support rod 23, it supports the multiple oil supply guides 22 and the multiple oil supply pipes 24 connected to each of these multiple oil supply guides 22. Support members 14L and 14R support the support bracket 25 and the multiple thread regulating guides 26 in a balanced manner in the left-right direction at two locations that are symmetrical when viewed from the front, so that the oil dispensing device 20 does not tilt to either the left or the right.

[0044] The support member 14L includes a sliding portion 16L that is movable vertically relative to the rail 32L described later, and a connecting portion 18L that is connected to the oil dispenser 20 and supports the connected oil dispenser 20. When the sliding portion 16L moves vertically, the connecting portion 18L moves vertically in conjunction with it.

[0045] Similarly, the support member 14R includes a sliding portion 16R that is movable vertically relative to the rail 32R described later, and a connecting portion 18R that is connected to the oil dispenser 20 and supports the connected oil dispenser 20. When the sliding portion 16R moves vertically, the connecting portion 18R moves vertically in conjunction with it.

[0046] [2-3. Lifting device] The lifting device 30 mainly comprises rails 32L, 32R (see Figure 2), wires 34L, 34R (see Figures 2 to 4), a winch 40 (see Figures 3 and 4), A sheaves 42L, 42R, B sheaves 44L, 44R, and C sheaves 46L, 46R (all see Figure 4), a force transmission shaft 36 for transmitting force to the winch 40 by operator operation (see Figures 3 and 4), a worm gear 50, and tension adjustment devices 60L, 60R.

[0047] The wire 34L, A sheave 42L, B sheave 44L, C sheave 46L, and tension adjustment device 60L are components provided in accordance with rail 32L. Furthermore, the wire 34R, A sheave 42R, B sheave 44R, C sheave 46R, and tension adjustment device 60R are components provided in accordance with rail 32R.

[0048] Furthermore, "Wire 34L, 34R" corresponds to the "two wires" of the present invention. Also, "Wire 34L" and "Wire 34R" correspond to either "one wire" or "another wire" of the present invention, respectively. Specifically, if "Wire 34L" corresponds to "one wire" of the present invention, then "Wire 34R" corresponds to "another wire" of the present invention, and if "Wire 34R" corresponds to "one wire" of the present invention, then "Wire 34L" corresponds to "another wire" of the present invention. In addition, "Winch 40" corresponds to the "winding member" of the present invention.

[0049] (rail) As shown in Figures 2 and 3, rails 32L and 32R are fixed to the front surface of the base member 12 such that their longitudinal direction is approximately vertical. Rails 32L and 32R are fixed to the base member 12 in a symmetrical manner.

[0050] The rails 32L and 32R are provided with the aforementioned sliding parts 16L and 16R so that they can slide vertically. By sliding against the rails 32L and 32R, the sliding parts 16L and 16R can move up and down approximately vertically relative to the base member 12, i.e., vertically. The front side of the rails 32L and 32R is marked with scales, for example, at 1 mm intervals, so that the amount of vertical movement can be grasped.

[0051] (Wire) The wires 34L and 34R are connected to the upper ends of the sliding parts 16L and 16R, respectively, so as to support them from above, in front of the base member 12, i.e., to suspend them.

[0052] Furthermore, the "part where wire 34L and sliding part 16L are connected" and the "part where wire 34R and sliding part 16R are connected" correspond to the "first connection part" or the "second connection part" of the present invention, respectively. Specifically, when "wire 34L" corresponds to "one wire" of the present invention, the "part where wire 34L and sliding part 16L are connected" corresponds to the "first connection part," and the "part where wire 34R and sliding part 16R are connected" corresponds to the "second connection part." Also, when "wire 34R" corresponds to "one wire" of the present invention, the "part where wire 34R and sliding part 16R are connected" corresponds to the "first connection part," and the "part where wire 34L and sliding part 16L are connected" corresponds to the "second connection part."

[0053] (winch) As shown in Figures 3 and 4, the winch 40 is positioned behind the base member 12. The winch 40 is a double-wire type (see Figure 3), with wires 34L and 34R wound around it. The winch 40 applies tension to the wires 34L and 34R, causing the sliding parts 16L and 16R (see Figure 3, except for sliding part 16L, which is shown in Figure 2) connected to the wires 34L and 34R to move up and down along the rails 32L and 32R (see Figure 3, except for rail 32L, which is shown in Figure 2), or to maintain their position in the vertical direction. In other words, the winch 40 can move the lubrication device 20, supported by the connecting parts 18L and 18R, in the vertical direction via the sliding parts 16L and 16R. The winch 40 is positioned to rotate with a center of rotation approximately perpendicular to the surface of the base member 12 (i.e., approximately horizontal in the front-to-back direction). The winch 40 is positioned on the upper left side of the rear of the base member 12, and the direction of the output wires 34L and 34R is diagonally downward to the right.

[0054] (A sieve) As shown in Figures 3 and 4, the A sheaves 42L and 42R are positioned between the winch 40 and the sliding parts 16L and 16R, respectively, and can be used to apply tension to the wires 34L and 34R, as well as to change the direction of the wires 34L and 34R. The A sheaves 42L and 42R are positioned to rotate with a center of rotation approximately perpendicular to the surface of the base member 12 (i.e., approximately horizontal front-to-back direction).

[0055] As shown in Figure 4, the A sheaves 42L and 42R are positioned behind the base member 12 and to the right and below the winch 40. The A sheaves 42L and 42R have the same axis of rotation as the winch 40 and are positioned to rotate with a center of rotation approximately perpendicular to the surface of the base member 12 (i.e., approximately horizontal front-to-back direction). The A sheaves 42L and 42R are positioned at approximately the same height, but the tension adjustment devices 60L and 60R, described later, can move each of the A sheaves 42L and 42R vertically. The A sheaves 42L and 42R change the direction of the wire 34L and 34R, which are output from the winch 40 diagonally downward to the right, to an upward direction.

[0056] Furthermore, "A Sheave 42L" and "A Sheave 42R" correspond to the "First Sheave" or "Second Sheave" of the present invention, respectively. Specifically, when "Wire 34L" corresponds to "One Wire" of the present invention, "A Sheave 42L" corresponds to "First Sheave" and "A Sheave 42R" corresponds to "Second Sheave". Also, when "Wire 34R" corresponds to "One Wire" of the present invention, "A Sheave 42R" corresponds to "First Sheave" and "A Sheave 42L" corresponds to "Second Sheave".

[0057] (B Seeve) As shown in Figures 3 and 4, the B sheaves 44L and 44R are positioned between the A sheaves 42L and 42R and the sliding parts 16L and 16R, respectively. The B sheaves 44L and 44R can be used to apply tension to the wires 34L and 34R, and can also change the direction of the wires 34L and 34R. The B sheaves 44L and 44R are positioned on the rear side of the base member 12, directly above the A sheaves 42L and 42R. The B sheaves 44L and 44R are positioned at approximately the same height. The B sheaves 44L and 44R are positioned so that they can rotate with a pivot point in a roughly horizontal left-right direction. The B sheaves 44L and 44R change the direction of the wires 34L and 34R, which are output upward from the A sheaves 42L and 42R, to a forward-diagonal upward direction (see Figure 3).

[0058] (C Seeve) As shown in Figures 3 and 4, the C sheaves 46L and 46R are positioned between the B sheaves 44L and 44R and the sliding parts 16L and 16R, respectively, and can be used to apply tension to the wires 34L and 34R, as well as to change the direction of the wires 34L and 34R. The C sheaves 46L and 46R are positioned diagonally forward and upward of the B sheaves 44L and 44R, and are located in holes formed across the base member 12 and the rails 32L and 32R. Like the B sheaves 44L and 44R, the C sheaves 46L and 46R are positioned so that they can rotate with a roughly horizontal left-right rotation center. The C sheaves 46L and 46R change the direction of the wires 34L and 34R, which are output from the B sheaves 44L and 44R diagonally forward and upward, to a vertically downward direction (see Figures 2 and 3).

[0059] (Force transmission axis) As shown in Figures 3 and 4, the force transmission shaft 36 is a longitudinal rod-shaped member whose axial direction is approximately perpendicular to the surface of the base member 12 (i.e., approximately horizontal in the front-to-back direction), and it penetrates the base member 12. An operator-operable handle 38 is provided at the front end of the force transmission shaft 36 (see Figures 2 and 3). When the handle 38 is rotated in the direction of the arrow in the arc shown in Figure 2, the force transmission shaft 36 rotates with its axial direction as the center of rotation. The "handle 38" corresponds to the "operating part" of the present invention.

[0060] (Worm gear) As shown in Figure 4, a worm gear 50 is positioned between the power transmission shaft 36 and the winch 40. The worm gear 50 has a worm (screw gear) 52 and a worm wheel (helical gear) 54 that is screwed onto the worm 52. The worm 52 is connected to the rear end of the power transmission shaft 36 so as to be coaxial with the power transmission shaft 36. When the power transmission shaft 36 rotates with its axial direction as the center of rotation, the worm 52 rotates coaxially with the power transmission shaft 36. The worm wheel 54 is coaxial with the winch 40 and is integrally constructed with the winch 40. Therefore, when the worm wheel 54 rotates, the winch 40 rotates in conjunction with it.

[0061] The worm gear 50 in this embodiment has a self-locking function that makes it difficult for rotational force to be transmitted from the worm wheel 54 to the worm 52. This self-locking function prevents the winch 40 from rotating due to the gravitational force of the lubrication device 20 even when the handle 38 is not being operated. The "worm gear 50" corresponds to the "locking mechanism" of this invention.

[0062] (Tension adjustment device) [2-4.Tension adjustment device] As shown in Figures 3 and 4, the tension adjustment devices 60L and 60R are positioned behind the base member 12, corresponding to the A sheaves 42L and 42R, respectively. The tension adjustment devices 60L and 60R can adjust the tension applied to the wires 34L and 34R by moving the A sheaves 42L and 42R in the vertical direction, respectively. The tension adjustment devices 60L and 60R can independently adjust the tension applied to the wires 34L and 34R by moving the A sheaves 42L and 42R in the vertical direction, respectively.

[0063] The tension adjustment devices 60L and 60R each comprise bolts 62L and 62R and fixing blocks 64L and 64R, respectively. The fixing blocks 64L and 64R are fixedly mounted to the rear side of the base member 12. The fixing blocks 64L and 64R have female threads that engage with the bolts 62L and 62R. The tension adjustment devices 60L and 60R are positioned so that the lower ends of the bolts 62L and 62R can contact the upper surfaces of the brackets 48L and 48R. The brackets 48L and 48R are positioned to move vertically relative to the base member 12. The brackets 48L and 48R each support the A sheaves 42L and 42R, respectively.

[0064] When bolts 62L and 62R are rotated, they move upward or downward relative to the fixing blocks 64L and 64R. The upper limit position of brackets 48L and 48R is determined by the vertical position of the lower end of bolts 62L and 62R. Therefore, moving bolts 62L and 62R downward relative to the fixing blocks 64L and 64R increases the tension applied to wires 34L and 34R compared to before the bolts 62L and 62R were moved. On the other hand, moving bolts 62L and 62R upward relative to the fixing blocks 64L and 64R decreases the tension applied to wires 34L and 34R compared to before the bolts 62L and 62R were moved. In this way, the tension adjustment devices 60L and 60R can adjust the tension applied to wires 34L and 34R by adjusting the vertical position of the lower end of bolts 62L and 62R. As a result, the balance of the multiple lubrication guides 22 arranged in the left-right direction can be adjusted, and consequently, tilting to either the left or right side can be prevented. In addition, the sliding parts 16L and 16R can slide smoothly against the rails 32L and 32R. Therefore, the distance from the nozzle 8 (see Figure 1) to the lubrication guide 22 can be kept approximately constant for all of the multiple lubrication guides 22 arranged in the left-right direction, contributing to the provision of stable quality.

[0065] In this embodiment, tension adjustment devices 60L and 60R are provided so that either A sheave 42L or A sheave 42R can be moved vertically, but the system is not limited to this configuration. For example, only one of the tension adjustment devices 60L or 60R may be provided. If at least one of the A sheave 42L or A sheave 42R can be moved vertically, the balance of the multiple lubrication guides 22 arranged horizontally can be adjusted in the horizontal direction, preventing them from tilting to one side or the other.

[0066] [3. Operation of the lifting device] The operation of the lifting device 30 will be explained with reference to Figures 2 to 5. Figure 5 is an example of a schematic diagram showing how the oil dispensing device 20 moves up and down. In Figure 5, the oil dispensing device 20 (oil supply guide 22, support bracket 25, and thread regulating guide 26) before lowering is shown by a dashed line, and the oil dispensing device 20 after lowering is shown by a solid line.

[0067] If the operator wants to change the vertical position of the oil dispenser 20, they rotate the handle 38 (see Figure 2) to the right or left. When the handle 38 is rotated, the power transmission shaft 36 (see Figure 3) rotates around its axial direction. When the power transmission shaft 36 rotates around its axial direction, the worm 52 (see Figure 4) rotates coaxially with the power transmission shaft 36. When the worm 52 rotates, the worm wheel 54 (see Figure 4), which is screwed to the worm 52, rotates, and the winch 40 rotates accordingly.

[0068] When the winch 40 rotates in the direction of winding the wires 34L and 34R, the sliding parts 16L and 16R connected to the wires 34L and 34R move upward along the rails 32L and 32R in proportion to the amount of rotation. As the sliding parts 16L and 16R move upward along the rails 32L and 32R, the lubrication device 20 moves upward, that is, from the position shown by the solid line in Figure 5 to the position shown by the dashed line.

[0069] On the other hand, when the winch 40 rotates in the opposite direction to the winding direction of the wires 34L and 34R, the sliding parts 16L and 16R connected to the wires 34L and 34R move downward along the rails 32L and 32R in proportion to the amount of rotation. As the sliding parts 16L and 16R move downward along the rails 32L and 32R, the lubrication device 20 moves downward, that is, from the position shown by the dashed line in Figure 5 to the position shown by the solid line.

[0070] [4. Effects and Benefits] According to the spinning equipment 1 of this embodiment, the oil application device 20 (support bracket 25, oil supply guide 22 and oil supply pipe 24 supported on the support bracket 25 via the support rod 23, yarn regulating guide 26, etc.) can be raised and lowered with a simple configuration that only requires operating the handle 38 to wind up or wind down the wires 34L and 34R connected to the sliding parts 16L and 16R. Moreover, wire 34L is connected to sliding part 16L, and wire 34R is connected to sliding part 16R. In other words, since wires 34L and 34R are connected to sliding parts 16L and 16R at two points on the left and right, respectively, the oil application device 20 can be raised and lowered while maintaining balance in the left-right direction, compared to the case where the sliding parts and wires are connected at one point.

[0071] Furthermore, according to the spinning equipment 1 of this embodiment, the winch 40 can wind up part or all of the wires 34L and 34R, respectively. The amount of wires 34L and 34R wound up by the winch 40 is determined according to the amount of rotation of the winch 40. In addition, a worm gear 50 with a self-locking function is arranged between the power transmission shaft 36 and the winch 40. Therefore, the oil application device 20 can be stopped at any vertical position according to the amount of operation of the handle 38, i.e., the amount of rotation of the winch 40. In particular, there are cases where it is desired to raise or lower the oil application device 20 not only when changing the yarn type, but also without changing the yarn type, but in this case the range of raising and lowering is smaller compared to when changing the yarn type. In this respect, according to the spinning equipment 1 of this embodiment, since the wires 34L and 34R can be stopped at any position, it is possible to accommodate cases where it is desired to raise or lower the oil application device 20 only slightly.

[0072] Furthermore, according to the spinning equipment 1 of this embodiment, when the handle 38 is operated, the force transmission shaft 36 rotates, and this force is transmitted to the winch 40 via the worm gear 50, causing the winch 40 to rotate. When the winch 40 rotates, the oil application device 20 moves up and down via the sliding parts 16L, 16R, i.e., support members 14L, 14R, which are connected to the wires 34L, 34R. According to the spinning equipment 1 of this embodiment, the oil application device 20 can be raised and lowered with such a simple configuration. Moreover, the force transmission shaft 36 is a longitudinal member extending in a direction substantially perpendicular to the surface of the base member 12, and the handle 38 is provided at the front end of the force transmission shaft 36. Therefore, the handle 38 can be installed in front of the oil dispenser 20 and at a distance from the oil dispenser 20, and the operator can operate the handle 38 at a distance from the oil dispenser 20 while visually checking the scales indicated on the rails 32L and 32R to control the vertical movement of the oil dispenser 20. Thus, the oil dispenser 20 can be raised and lowered without stopping the operation of the spinning equipment 1, even while the spinning equipment 1 is in operation. "A distance from the oil dispenser 20" is a position within the range in which the operator can operate the handle 38 while visually checking the vertical movement of the oil dispenser 20. More specifically, "a distance from the oil dispenser 20" is a position within the range in which the operator can operate the handle 38 while visually checking the scales indicated on the rails 32L and 32R (rail 32L in this embodiment), for example, a position within a range of 1m in front of the oil dispenser 20.

[0073] Furthermore, according to the spinning equipment 1 of this embodiment, the multiple lubrication guides 22 are arranged regularly in the left-right direction when viewed from the front. The multiple lubrication guides 22, which are arranged regularly in the left-right direction when viewed from the front, are supported by support members 14L and 14R. The wires 34L and 34R support the lubrication device 20 at the connection point with the sliding parts 16L and 16R so as not to cause an imbalance in weight distribution in the left-right direction. As a result, the sliding parts 16L and 16R can slide smoothly against the rails 32L and 32R. In addition, the distance from the die 8 to the lubrication guide 22 (i.e., the height position) can be made approximately the same among the multiple lubrication guides arranged in the left-right direction without any imbalance. In particular, the spinning equipment 1 of this embodiment is equipped with tension adjustment devices 60L and 60R, and the tension of at least one of the wires 34L and 34R can be changed by changing the vertical position of at least one of the A sheaves 42L and A sheaves 42R. Therefore, the height positions of the multiple fueling guides 22 in the left-right direction can be adjusted to be approximately the same, and the distance from the nozzle 8 to the fueling guide 22 can be made approximately the same among the multiple fueling guides 22 arranged in the left-right direction without any bias.

[0074] Furthermore, an imbalance in the weight distribution of the lubrication device 20 in the left-right direction may occur even if the difference between the height position of the lubrication guide 22 on rail 32L and the height position of the lubrication guide 22 on rail 32R is 1 mm. For this reason, it is preferable to ensure that the height position of the lubrication guide 22 on rail 32L and the height position of the lubrication guide 22 on rail 32R are the same. In this embodiment, the support members 14L, 14R (more specifically, the sliding parts 16L, 16R) and the lubrication guide 22 are integrally constructed. Therefore, the wires 34L, 34R support the lubrication device 20 via the sliding parts 16L, 16R such that the difference between the scale at the upper end of the sliding part 16L and the scale at the upper end of the sliding part 16R is 1 mm or less (more preferably, the scale at the upper end of the sliding part 16L and the scale at the upper end of the sliding part 16R are the same value).

[0075] [5. Variant] Next, modified examples of the lifting device 30 of this embodiment will be described below. In the first to third modified examples described below, points that differ from the above-described embodiment will be mentioned, while points that are not mentioned will be the same as in the above-described embodiment.

[0076] [5-1. First variation] In this embodiment, A sheaves 42L, 42R, B sheaves 44L, 44R, and C sheaves 46L, 46R are arranged between the winch 40 and the sliding parts 16L, 16R, but the number and position of the sheaves are not limited to this.

[0077] For example, only some of the sheaves among A sheaves 42L, 42R, B sheaves 44L, 44R, and C sheaves 46L, 46R may be placed between the winch 40 and the sliding parts 16L, 16R.

[0078] Furthermore, a sheave different from the A sheaves 42L, 42R, B sheaves 44L, 44R, and C sheaves 46L, 46R (hereinafter referred to as "D sheave") may be placed between the winch 40 and the sliding parts 16L, 16R. When a D sheave is placed between the winch 40 and the sliding parts 16L, 16R, the D sheave may be placed in addition to the A sheaves 42L, 42R, B sheaves 44L, 44R, and C sheaves 46L, 46R, or some of the A sheaves 42L, 42R, B sheaves 44L, 44R, and C sheaves 46L, 46R may be placed along with the D sheave, or the D sheave may be placed without any of the A sheaves 42L, 42R, B sheaves 44L, 44R, and C sheaves 46L, 46R.

[0079] In other words, by rotating the winch 40, it is sufficient to move the lubricant dispensing device 20, which is supported by the connecting parts 18L and 18R via the sliding parts 16L and 16R, in a balanced vertical direction. The number and position of the sheaves arranged between the winch 40 and the sliding parts 16L and 16R are not limited to the configuration described in this embodiment.

[0080] [5-2. Second variation] Next, a second modified example, in which the lifting device 30 of this embodiment has been modified, will be described with reference to Figure 6. Figure 6 is an example of a schematic diagram showing the lifting device 70 according to the second modified example. In describing the lifting device 70 according to the second modified example, components having the same configuration as in the above-described embodiment will be denoted by the same reference numerals and their descriptions will be omitted as appropriate.

[0081] As shown in Figure 6, the lifting device 70 is positioned above the base member 12 and comprises a shaft member 72, a rotating roller 74, and a rotating operating unit 76.

[0082] The shaft member 72 is a longitudinal shaft member extending in a substantially horizontal left-right direction, and is the axis of rotation of the rotating roller 74. The rotation operating part 76 is a disc-shaped member and is integrally configured with the shaft member 72 so as to be substantially concentric with the shaft member 72. By rotating the rotation operating part 76, the operator can rotate the rotating roller 74 with the shaft member 72 as the center of rotation.

[0083] Although not shown in the diagram, the lifting device 70 is equipped with a locking mechanism to prevent the rotation of the rotating roller 74. When the operator rotates the rotating control unit 76, they release the locking mechanism before operating it.

[0084] Wires 34L and 34R are wound around the rotating roller 74. When the operator rotates the rotating control unit 76, the sliding parts 16L and 16R, to which the ends of the wires 34L and 34R are connected, move vertically along the rails 32L and 32R. As the sliding parts 16L and 16R move vertically, the support bracket 25 and the thread regulating guide 26 also move vertically. In this way, the lubrication device 20 (support bracket 25, lubrication guide 22 and lubrication pipe 24 supported on the support bracket 25 via the support rod 23, thread regulating guide 26, etc.) can be raised and lowered.

[0085] Although not shown in Figure 6, grooves may be formed in the rotating roller 74 to which the wires 34L and 34R can be wound.

[0086] According to the second modified lifting device 70, the oil application device 20 can be raised and lowered with a simple configuration that only requires operating the rotating operation unit 76 to rotate the rotating roller 74. Moreover, since the wire 34L is connected to the sliding part 16L and the wire 34R is connected to the sliding part 16R, the oil application device 20 can be raised and lowered while maintaining balance in the left-right direction, compared to the case where the wire and the sliding part are connected at one point.

[0087] Furthermore, according to the second modified lifting device 70, the amount of wire 34L and 34R to be wound is determined according to the amount of rotation of the rotating roller 74. The lifting device 70 is also equipped with a locking mechanism to prevent the rotation of the rotating roller 74. Therefore, the oil application device 20 can be stopped at any vertical position according to the amount of operation of the rotation operation unit 76, i.e., the amount of rotation of the rotating roller 74. For this reason, it is possible to accommodate cases where, for example, the type of yarn is not to be changed and it is desired to slightly raise or lower the oil application device 20.

[0088] Furthermore, according to the second modified lifting device 70, the rotary operating unit 76 is located above the base member 12, that is, away from the oil application device 20. Therefore, the operator can operate the rotary operating unit 76 from a position away from the oil application device 20. Thus, the oil application device 20 can be raised and lowered without stopping the operation of the spinning equipment, even while the spinning equipment is in operation.

[0089] [5-3. Third Variation] Next, a third modified example of the lifting device 30 of this embodiment will be described.

[0090] Figure 7 is a diagram illustrating the lifting device 300 according to the third modified example, and is a schematic diagram showing an example of a rear view of the lubricant device 100.

[0091] In this third modified example, the lifting device 300 has a different configuration from the lifting device 30 described above, and therefore uses a different reference numeral than the lifting device 30. Furthermore, the lubricant dispenser 100 is equipped with a lifting device 300 that has a different configuration from the lifting device 30 described above, and therefore uses a different reference numeral than the lubricant dispenser 10. Additionally, the base member 120 also uses a different reference numeral than the base member 12 described above.

[0092] The lifting device 300 is similar to the lifting device 30 in that it includes rails 32L, 32R (see Figure 2), wires 34L, 34R, winch 40, power transmission shaft 36 (see Figures 3 and 4), and worm gear 50 (see Figure 4). However, the lifting device 300 does not have the sheaves 42L, 42R, 44L, 44R, 46L, 46R (see Figures 3 and 4) that the lifting device 30 has. In addition, the lifting device 300 has tension adjusters 94L, 94R instead of tension adjusters 60L, 60R that the lifting device 30 has.

[0093] Furthermore, in this third modified example, the winch 40 has the same configuration as the winch 40 described with reference to Figures 3 and 4. However, as described with reference to Figures 3 and 4, it is not arranged to rotate with a rotation center approximately perpendicular to the plane of the base member 12 (see Figure 3), but rather is arranged to rotate with a rotation center approximately vertically. The wires 34L and 34R are output from the winch 40 in an approximately horizontal direction. Note that the rotation direction of the winch 40 is not limited to this.

[0094] Furthermore, the worm gear 50 (see Figure 4) is positioned such that when the handle 38 (see Figure 3) is operated and the power transmission shaft 36 (see Figure 3) rotates with its axis of rotation as the center of rotation, the winch 40 rotates.

[0095] As shown in Figure 7, the winch 40 is mounted on the bracket 84. The bracket 84 has a winch support portion 841 on which the winch 40 is mounted, and a vertical planar portion 842 that is substantially perpendicular to the surface of the base member 120. The planar portion 842 is substantially perpendicular to the output direction of the wires 34L and 34R that are output from the winch 40.

[0096] Incidentally, as explained with reference to Figures 3 and 4, the C sheaves 46L and 46R are positioned in holes formed across the base member 12 (see Figures 3 and 4) and the rails 32L and 32R (see Figure 2), respectively. In this third modified example, the base member 120 has openings 121L and 121R formed in the base member 12 at approximately the same locations as the holes where the C sheaves 46L and 46R are positioned.

[0097] For example, in Figure 2, the upper ends of rails 32L and 32R are positioned higher than the holes where C sheaves 46 and 46R are placed. However, in this third modified example, the upper ends of rails 32L and 32R are positioned lower than the openings 121L and 121R. However, the position of the upper ends of rails 32L and 32R is not particularly limited.

[0098] On the rear surface of the base member 120, vertically elongated rectangular support plates 88L and 88R are attached in approximately the same positions as the rails 32L and 32R (see Figure 2) in the left-right direction. Fixing members 92L and 92R, which will be described later, are attached to the upper ends of these support plates 88L and 88R.

[0099] Between the part where the wire 34L and the sliding part 16L (see Figure 2) are connected (first connection part) and the winch 40, more specifically between the flat part 842 of the bracket 84 and the fixing member 92L, the wire 34L is connected. Insert into the interior A flexible outer cable 86L is provided. Similarly, the wire 34R is connected to the part where the wire 34R and the sliding part 16R (see Figure 2) are connected (second connection part) and the winch 40, more specifically, between the flat part 842 of the bracket 84 and the fixing member 92R. Insert into the interior A flexible outer cable 86R is provided.

[0100] One end 861L of the outer cable 86L (hereinafter referred to as the "input end 861L") is, Insert into the interiorThe wire 34L is connected to the flat portion 842 of the bracket 84 such that it is output in a direction substantially perpendicular to the flat portion 842 of the bracket 84. The other end 862L of the outer cable 86L (hereinafter referred to as the "output end 862L") is connected to the fixing member 92L.

[0101] Similar to the input end 861L of the outer cable 86L, ​​one end 861R of the outer cable 86R (hereinafter referred to as "input end 861R") is Insert into the interior The wire 34R is connected to the flat portion 842 of the bracket 84 such that it is output in a direction approximately perpendicular to the flat portion 842 of the bracket 84. The other end 862R of the outer cable 86R (hereinafter referred to as the "output end 862R") is connected to the fixing member 92R. Details of the connection between the output end 862R and the fixing member 92R will be described later.

[0102] Outer cables 86L and 86R are, for example, made of a metal underwinding (such as hard steel wire like SWRH62A) coated with resin (such as polyvinyl chloride or polyethylene).

[0103] The wire 34L is slidable within the outer cable 86L and relative to the outer cable 86L. It is preferable, but not essential, that a cylindrical member with a low coefficient of friction (for example, a liner tube made of polyethylene with added molybdenum) be provided radially inside the outer cable 86L to improve sliding properties with the wire 34L.

[0104] The wire 34R is slidable within the outer cable 86R and relative to the outer cable 86R. Similar to the outer cable 86L, ​​it is preferable, but not essential, to provide a cylindrical member with a low coefficient of friction on the radially inner side of the outer cable 86R to improve sliding with the wire 34R.

[0105] Intermediate members 90L and 90R are attached to the support plates 88L and 88R below the fixing members 92L and 92R. Intermediate member 90L supports the outer cable 86L at an intermediate position between the flat portion 842 of the bracket 84 and the fixing member 92L. Similarly, intermediate member 90R supports the outer cable 86R at an intermediate position between the flat portion 842 of the bracket 84 and the fixing member 92R.

[0106] Figure 8 is a diagram illustrating the lifting device 300 according to the third modified example, and is a schematic diagram showing an example of the area around the opening 121R formed in the base member 120. In Figure 8, an example is shown of a cross-section viewed from the right, which crosses in a vertical direction perpendicular to the surface of the base member 120, approximately in the center of the opening 121R in the left-right direction. In Figure 8, the base member 120, a part of the wire 34R, a part of the outer cable 86R, a part of the fixing member 92R, and the tension adjustment device 94R are shown as cross-sectional views.

[0107] As shown in Figure 8, the fixing member 92R has a main body portion 921R that is attached to the support plate 88R, and a flat portion 922R that is substantially horizontal when the main body portion 921R is attached to the support plate 88R.

[0108] The tension adjustment device 94R includes an adjuster bolt 941R and an adjustment nut 946R. The adjuster bolt 941R has a head 942R and a shaft 944R with a threaded portion formed on its outer circumference. A groove 943R is formed in the head 942R. The shaft 944R has an insertion hole 945R through which the wire 34R can be inserted. The inner circumference of the adjustment nut 946R has a threaded portion that engages with the threaded portion formed on the outer circumference of the shaft 944R. The shaft 944R passes through a through hole 923R formed in the flat portion 922R of the fixing member 92R in a substantially vertical direction. The inner circumference of the through hole 923R has a threaded portion that engages with the threaded portion formed on the outer circumference of the shaft 944R. When the adjustment nut 946R is turned, the adjuster bolt 941R moves in a substantially vertical direction relative to the flat portion 922R. Therefore, by turning the adjustment nut 946R, the distance between the flat portion 842 of the bracket 84 (see Figure 7) and the flat portion 922R of the fixing member 92R of the wire 34R can be changed, and consequently, the tension of the wire 34R can be changed.

[0109] The output end 862R of the outer cable 86R is connected to the groove 943R formed in the head 942R of the adjuster bolt 941R. Insert This is done. At this time, it is preferable to ensure that the output end 862R of the outer cable 86R does not come out of the groove 943R, for example, by press-fitting it. It is also preferable to interpose a cylindrical member made of an elastic material such as rubber between the inner circumferential surface of the groove 943R and the outer circumferential surface of the output end 862R of the outer cable 86R, as this makes it difficult for the output end 862R of the outer cable 86R to come out of the groove 943R. In this way, the output end 862R of the outer cable 86R is connected to the fixing member 92R via the adjuster bolt 941R.

[0110] Outer cable 86R Insert into the interior The wire 34R is inserted through the insertion hole 945R formed inside the shaft portion 944R, and its tip is connected to the sliding portion 16R (see Figures 2 and 3).

[0111] The outer cable 86R is curved upward in an arc with a predetermined radius of curvature on the side of the winch 40 (see Figure 7) that is closer to the output end 862R. The output end 862R of the outer cable 86R is positioned approximately vertically into the groove 943R formed in the head 942R of the adjuster bolt 941R. Insertion It is being done.

[0112] In Figure 8, the area around the opening 121R formed in the base member 120 was described, but the same applies to the area around the opening 121L formed in the base member 120. That is, the various components around the opening 121L, such as the fixing member 92L, the tension adjustment device 94L, and the tension adjustment device 94L, are the same as the various components around the opening 121R, such as the fixing member 92R, the tension adjustment device 94R, and the tension adjustment device 94R. Furthermore, the relationships between the various components around the opening 121L, such as the method of connecting the outer cable 86L to the fixing member 92L, are the same as the relationships between the various components around the opening 121R. Therefore, the description of the area around the opening 121L will be omitted.

[0113] Thus, the lifting device 300 of the third modified example does not have the sheaves 42L, 42R, 44L, 44R, 46L, and 46R as described with reference to Figures 3 and 4, and instead has wires 34L and 34R. Insert into the interior It is equipped with outer cables 86L and 86R. Therefore, the configuration of the lifting device 300 can be simplified. Also, for example, the effort of attaching wires 34L and 34R to each sheave 42L, 42R, 44L, 44R, 46L, and 46R can be eliminated, and the wires 34L and 34R are Insert into the interiorBy simply positioning the outer cables 86L and 86R, work efficiency can be improved. Furthermore, productivity can be improved because, for example, the wires 34L and 34R will not come off each sheave 42L, 42R, 44L, 44R, 46L, and 46R, and the sheaves 42L, 42R, 44L, 44R, 46L, and 46R will not be damaged. In addition, the outer cables 86L and 86R offer greater flexibility in installation location compared to each sheave 42L, 42R, 44L, 44R, 46L, and 46R. Therefore, even in cases where there are restrictions on the installation location (for example, when installing a lifting device on an existing spinning machine), the lifting device 300 can be easily installed.

[0114] Furthermore, the output end 862R of the outer cable 86R is curved to have a predetermined radius of curvature into the groove 943R formed in the head 942R of the adjuster bolt 941R, and then extends in a substantially vertical direction. Insertion This is also the case for the output end 862L of the outer cable 86L. As a result, the oil dispenser 20 (see Figure 2) can be smoothly raised and lowered via the sliding parts 16L and 16R (see Figures 2 and 3). In particular, when raising the oil dispenser 20, it is possible to suppress the dispersion of the force lifting the oil dispenser 20 in directions other than the vertical, thereby enabling the oil dispenser 20 to be raised efficiently.

[0115] Furthermore, the tension of at least one of the wires 34L and 34R can be changed using the tension adjustment device 94L or tension adjustment device 94R. Therefore, while enabling the oil application device 20 to be raised and lowered with a simple structure using the lifting device 300, the distance from the nozzle 8 (see Figure 1) to the oil supply guide 22 (see Figure 2) can be made approximately the same among the multiple oil supply guides 22 arranged in the left-right direction without any bias.
