The described embodiment is merely one embodiment of the present invention and not all embodiments. For simplicity and clarity, the specification does not describe all features of actual embodiments. In order to realize the specific purpose of the developer, in the process of actually developing the embodiment, many matters and conditions must be determined, for example, it must be adapted to the restriction conditions related to the system and service. However, it should be understood that these limiting conditions may vary with different embodiments. In addition, although the development work may be very complicated and time consuming, it should be understood that the development work described above is merely a normal work for those skilled in the art with reference to this specification. It is.

  Furthermore, the elements and features described in one drawing or embodiment of the invention may be combined with the elements and features shown in one or more other drawings or embodiments. In order to avoid obscuring the present invention, in the drawings and detailed description, only the structure and / or processing steps of the apparatus closely related to the solution of the present invention are described. Indications and descriptions relating to parts and processes known to those skilled in the art are omitted. Based on the embodiments of the present invention, all embodiments conceived by those skilled in the art without creative activities are included in the protection scope of the present invention.

  The terminology such as “first” and “second” in the present invention is for distinguishing different steps, devices, modules, and the like, does not indicate a specific technical meaning, and requires an indispensable logic between them. It is clear that the target order is not shown.

  In an embodiment of the present invention, the spinning unit including a temperature control unit and a spinning unit that are detachably stacked, and the spinning unit is changed in order to change the direction of the spinning unit to a direction in which the spinning unit is easily maintained. An elastic fiber dry-spinning structure is provided that includes lifting and lowering, horizontal movement, and a rotational movement control unit that rotates the horizontal direction as an axis.

  The raising / lowering includes a vertical movement in which the spinning unit moves up or down to a certain reference position, and when the central axis of the spinning unit is in a vertical direction, the raising / lowering moves up and down to a reference position with the spinning unit on a vertical plane. It is a move. The horizontal movement (translation) includes left and right parallel movement to a certain reference position of the spinning section. When the central axis of the spinning unit is a vertical direction, the translation is a movement of the spinning unit to a certain reference position in a horizontal plane, and a horizontal movement along the major axis direction of the spinning unit, or a minor axis of the spinning unit. It can move back and forth along the direction. The direction in which the spinning unit is easy to maintain includes, but is not limited to, that the spinning unit is upward. The maintenance includes, but is not limited to, cleaning and / or replacement.

  In the dry spinning production process of elastic fibers such as spandex, the spinning section is generally provided above the spinning box. The spinning unit is adjacent to the spinning box, and the spinning box can include a spinning passage, but is not limited to such a configuration. The spinneret of the spinning unit faces the spinning passage, and the polymer solution for the elastic fiber is blown into the spinning passage from each spinneret of the spinning unit, and subsequent steps such as solvent volatilization of the elastic fiber are performed. The polymer solution for dry spinning of elastic fibers has a predetermined corrosiveness and viscosity, and when used for a long time, the solution or impurities accumulate on each spinneret of the spinning section. There is a possibility of blocking. For this reason, the spinning unit generally needs to be regularly maintained in a certain maintenance cycle.

  For example, when the spinning box is located below the spinning section, the spinning unit faces downward in a normal spinning operation (that is, each spinneret of the spinning unit spins toward the spinning passage below it), and the spinning is performed. When the unit faces down, maintenance such as cleaning and replacement is inconvenient. The rotational movement control unit can raise the spinning unit to separate the spinning unit and the spinning box located below the spinning unit. Further, in order to shift the spinning section and the spinning box, the spinning section can be moved horizontally. Further, in order to change the direction of the spinning unit to a direction in which the spinning unit can be easily maintained, the spinning unit is rotated about the horizontal direction, for example, until the spinning unit is in a state in which the spinning unit faces upward. It can be rotated about the horizontal direction. Thus, the spinning unit and the temperature control unit can be separated, and another spinning unit (for example, a spare clean spinning unit) and the temperature control unit can be detachably stacked. After the exchange is completed, the rotational movement control unit can move or rotate in the reverse direction according to the original movement locus. For example, in order to change the direction of the spinning unit to a direction in which another spinning unit can easily spin into the spinning box (for example, the spinneret of the spinning unit is downward), the spinning unit is rotated about the horizontal direction. Let Thereafter, the spinning section is moved horizontally so that the spinning section and the spinning box are aligned with each other, and the spinning section is lowered to connect the spinning section and the spinning box. It can be returned to the operating state.

  In one embodiment of the present invention, the temperature control unit and the spinning unit included in the dry spinning portion of the elastic fiber are two units that are detachably stacked. In the process of maintaining the spinning section, the entire spinning section is moved up and down, horizontally moved, and rotated about the horizontal direction as an axis by the rotational movement control section. Then, after changing the direction of the spinning unit to the direction in which the spinning unit is easy to maintain, it is only necessary to separate and remove the spinning unit and the temperature control unit, and it is not necessary to remove the entire spinning unit. Therefore, the range of parts requiring maintenance such as cleaning and replacement is reduced, and the amount of maintenance work such as cleaning and replacement is reduced. Further, since the spare spinning unit can be replaced, the online maintenance time is short, and the influence on the spinning production is small. The replaced spinning unit can perform off-line maintenance such as cleaning and parts replacement, and the influence on the on-line production of spinning due to the time required for off-line maintenance of the part can be avoided. As a result, the time for interrupting the spinning production for maintenance is shortened and the production efficiency is improved.

  In an embodiment of the present invention, the spinning unit preferably includes a rectangular plate provided with a plurality of rows of spinning holes in which at least one spinneret (Nozzle) is incorporated. Specifically, the spinning holes in each row include a plurality of spinning holes arranged at intervals along the longitudinal direction of the rectangular plate, and one or a plurality of spinning caps may be provided in each spinning hole. it can. The temperature control unit may include a housing through which the temperature control medium can flow. The housing is provided with a plurality of rows of polymer solution passages isolated from each other, and each polymer solution passage communicates with each spinning hole. The polymer solution for elastic fibers is fed into the corresponding spinning hole through the polymer solution passage, and is ejected from the spinneret of the corresponding spinning hole. The spinning unit of the solution can be adapted to a spinning box including a rectangular spinning passage, and more fiber bundles can be ejected in a limited space, thereby improving the production capacity. In the production of actual elastic fibers, the spinning unit may be a single unit, and the entire removal and assembly are convenient. The spinning unit may include a plurality of sub-spinning units to be joined. In this solution, the production capacity per unit time is high, and the spinning unit of the spinning section can be removed or assembled in stages. The production capacity per unit time of elastic fibers such as spandex is constantly improving. In the conventional maintenance method described in the background art, the time for suspending production at the time of maintenance is extended, the continuous operation of the apparatus is hindered, and the production efficiency is lowered. On the other hand, it is obvious that the technical solution of the present invention has advantages such as a small range requiring maintenance, fast replacement of the spinning unit, short interruption time, and high work efficiency.

  It is preferable that the spinning unit further includes at least one weighing device and a connection port conversion unit, and the weighing device, the connection port conversion unit, the temperature control unit, and the spinning unit are sequentially stacked. The spinning section provided by the solution has a small volume and a compact structure. When the spinning unit needs to be maintained, the metering device, connection port conversion unit, temperature control unit and spinning unit are moved up and down, horizontally moved, and rotated around the horizontal direction as an axis to maintain the orientation of the spinning unit. The ease of maintenance improves the convenience of maintenance and control.

  Preferably, the spinning section further includes at least one metering drive device that drives the at least one metering device. In the solution, when maintenance of the spinning unit is necessary, the metering drive device, the metering device, the connection port conversion unit, the temperature control unit and the spinning unit are integrally moved up and down, horizontally moved, and rotated around the horizontal direction as an axis, By making the orientation of the spinning unit easier to maintain, the convenience of maintenance and control is improved.

  Preferably, the elastic fiber dry spinning structure according to an embodiment of the present invention further includes a moving bracket that supports the raising / lowering, horizontal movement and / or rotation of the spinning unit. In the solution, the moving bracket can effectively improve the stability of the overall spinning of the spinning section, the overall horizontal movement, and / or the overall rotation. The specific structure of the moving bracket can be designed flexibly according to actual needs, and is not limited in the present invention.

  It is preferable that the spinning section is rotatably connected to the moving bracket via at least one rotating shaft. For example, it is possible to provide one or a plurality of rotating shafts in the spinning section and connect to the moving bracket via the rotating shaft. In the above configuration, the entire spinning unit can be rotated on the moving bracket by driving the rotational movement control unit, and the rotational stability is good.

  The rotational movement control unit preferably includes a first elevating drive mechanism that drives the spinning unit to move up and down together with the moving bracket. The first elevating drive mechanism may include an elevating cylinder, but is not limited to the configuration. The spinning unit and the moving bracket can be moved up and down together by a driving force supplied from the first elevating drive mechanism. Stability when moving up and down is obtained. Here, the system for supplying the driving force of the first elevating drive mechanism can be determined flexibly according to the actual arrangement of the apparatus. Or the raising / lowering mechanism which has a predetermined drive system flexibly can be selected as a 1st raising / lowering drive mechanism as needed of arrangement | positioning of an actual apparatus. For example, the first elevating drive mechanism can drive the spinning unit so as to elevate together with the moving bracket from above. Here, the solution is driven by the push-pull driving force of the first lifting / lowering drive mechanism so that the spinning unit is lifted / lowered together with the entire moving bracket, and the lifting / lowering driving mechanism is made flexible by fully utilizing the space above the spinning unit Can be arranged. For example, the first raising / lowering driving mechanism can be driven so as to raise and lower the spinning portion together with the moving bracket from below the spinning portion. Here, the solution means drives the spinning unit to move up and down together with the entire moving bracket by a system such as expansion and contraction of the drive arm of the first lifting drive mechanism, and fully utilizes the space below the spinning unit to raise and lower the drive mechanism. Can be arranged flexibly.

  The moving bracket is provided with at least one moving bracket guide portion extending along a lifting direction, and the rotational movement control unit drives the spinning unit to move up and down along the moving bracket guide portion. It is preferable to provide an elevating drive mechanism. The second lifting drive mechanism may include a lifting cylinder, but is not limited to that configuration. The spinning section can be moved up and down along the moving bracket guide section by the driving force supplied by the second lifting drive mechanism, so that stability is obtained during the up-and-down movement. The method of supplying the driving force of the second elevating drive mechanism can be determined flexibly according to the actual arrangement of the apparatus. Or the raising / lowering mechanism which has a predetermined drive system flexibly can be selected as a 2nd raising / lowering drive mechanism according to the necessity of arrangement | positioning of an actual apparatus. For example, the second raising / lowering driving mechanism can drive the spinning unit to move up and down along the movable bracket guide unit from below the spinning unit, and the solving means includes a driving arm of the second raising / lowering driving mechanism. The spinning unit can be driven to move up and down along the movable bracket guide unit by a method such as expansion and contraction, and the elevating drive mechanism can be flexibly arranged by fully utilizing the space below the spinning unit. For example, the second raising / lowering driving mechanism can drive the spinning part to move up and down along the moving bracket guide part from above the spinning part, and the solution means push-pull of the second raising / lowering driving mechanism. The spinning unit can be driven by the driving force so as to move up and down along the moving bracket guide unit, and the lifting drive mechanism can be flexibly arranged by fully utilizing the space above the spinning unit.

  More preferably, the moving bracket guide part is provided with at least one position restriction hole that is fitted to a position restriction part and restricts the position when the spinning part moves up and down to a predetermined position. The shape and size of the position limiting hole can be designed according to actual needs, and can be designed very flexibly. The position limiting component may be provided with a position limiting pin adapted to the position limiting hole, but is not limited to the configuration. In the solving means, when the spinning section is moved up and down to a predetermined position by the position limiting hole and the position limiting component, the position is limited and then the horizontal movement operation is performed. The solution is simple and easy to implement, and is effective in improving the stability of the operation.

  The rotational movement control unit includes a first slide rail parallel to the first axial direction of the spinning unit, and after the spinning unit is moved up and down to a predetermined position, the rotational movement control unit moves horizontally along the first slide rail. Used to limit. For example, the spinning unit may include a long axis extending along the longitudinal direction and a short axis extending along the width direction. The first axis may be a long axis. In the solution, the spinning section or the spinning section and the moving bracket are both moved to a space extending along the longitudinal direction of the spinning unit, and then the rotation of the spinning section is easily controlled in the space. On the other hand, the first axis may be a short axis. In the solution, the spinning unit or the spinning unit and the moving bracket are both moved to a space extending along the width direction of the spinning unit, This makes it easy to control the rotation of the spinning section. In the above solution, the spatial arrangement can be set flexibly, and the convenience of operation can be improved. More preferably, the rotational movement control unit further includes a moving slide rail parallel to the first axis direction of the spinning unit.

  More preferably, the rotational drive mechanism having the self-locking function includes an electric or manual reduction gear having a self-locking function. In the manual speed reducer, the rotation angle can be controlled by a method such as a handle wheel, and the control is convenient and low cost, but is not limited thereto.

  (1) Hereinafter, referring to FIGS. 1 to 2 g, a preferred embodiment of the present invention will be described by taking as an example a configuration in which the spinning unit includes a metering drive device, a metering device, a connection port conversion unit, a temperature control unit, and a spinning unit. Further explanation will be given. Even in the case of a spinning unit having other structures, the description thereof will be omitted if the embodiments are similar.

  As shown in FIG. 1, an elastic fiber dry spinning structure according to an embodiment of the present invention includes a spinning unit 1, a moving bracket 2, and a rotational movement control unit. The spinning unit 1 includes at least one metering device 11, a connection port conversion unit 12, a temperature control unit 13, a spinning unit 14, and at least one metering drive device 15. The positions of the weighing device 11, the connection port conversion unit 12, the temperature control unit 13, the spinning unit 14, and the weighing drive device 15 can not be changed relatively, and are integrated in the vertical direction. At least the temperature control unit 13 and the spinning unit 14 are detachable. Rotating shafts 16 are provided at both ends of the spinning unit 1. The spinning unit 1 is connected to the moving bracket 2 via the rotating shaft 16, and the entire spinning unit 1 can be rotated by the moving bracket 2. The rotational movement control unit includes a first elevating drive mechanism 41, a first slide rail 31, a movable slide rail 32, and the rotational drive mechanism 6. The first slide rail 31 and the movable slide rail 32 are in contact with each other and are provided in the longitudinal direction of the spinning unit 14, and the movable slide rail 32 moves up and down together with the movable bracket 2 along with the spinning unit 1.

  As shown in FIG. 2a, when the spinning section 1 is in a normal spinning operation state, the spinning unit 14 is provided at the top of the spinning box and communicates with the spinning passage 5, and the spinning unit 14 faces downward. When it is necessary to replace the spinning unit 14, the spinning operation is interrupted.

As shown in FIG. 2 b, the first elevating drive mechanism 41 moves the moving slide rail 32, the moving bracket 2 and the entire spinning unit 1 in the vertical direction so as to rise to the same height as the first slide rail 31. To drive. As shown in FIG. 2c, a driving force that moves horizontally along the longitudinal direction of the spinning unit is applied to the entire moving bracket 2 and the spinning unit 1 (this driving force can be applied manually, for example, a propulsive force, or The movable bracket 2 and the entire spinning unit 1 are moved horizontally along the movable slide rail 32 to the first slide rail 31. As shown in FIG. 2d, after the spinning unit 1 is completely moved to the first slide rail 31, it shifts completely and spinning passage. As shown in FIGS. 2e and 2f, the rotary drive mechanism 6 may include a manual worm speed reducer, but is not limited to that structure. The rotation drive mechanism 6 outputs power to the rotating shaft 16 and rotates the entire spinning unit in the moving bracket 2. As shown in FIG. 2g, the spinning unit is rotated by a predetermined angle so that the direction of the spinning unit of the spinning section is easy to maintain. For example, after 180 degrees forward rotation, the spinning unit of the spinning section is reversed and turned upward. In this state, the spinning unit 14 can be removed and replaced with another spinning unit 14.

  After the replacement of the spinning unit 14 is completed, the power of the rotational drive mechanism 6 is output to the rotating shaft 16, the entire spinning unit is rotated in reverse by the moving bracket 2, and rotated by a predetermined angle to change the direction of the spinning unit in the spinning unit. The direction in which the spinning passage 5 is easily spun is set. For example, after 180 degrees reverse rotation, the spinning unit of the spinning section is reversed and turned downward. Next, a driving force that horizontally moves along the major axis direction of the spinning unit is applied to the entire moving bracket 2 and the spinning unit 1, and the moving bracket 2 and the spinning unit 1 are moved to the moving slide rail 32 along the first slide rail 31. After the horizontal movement as a whole and the spinning section 1 has completely moved to the moving slide rail 32, the spinning path and the upper and lower sides coincide with each other. Thereafter, the first raising / lowering drive mechanism 41 drives the moving slide rail 32, the moving bracket 5 and the entire spinning unit 1 to move vertically to descend to the spinning unit 14 and connect to the spinning passage 5.

  Thus, replacement maintenance of the spinning unit 14 is completed, and spinning production of elastic fibers can be resumed. The removed spinning unit 14 can be subsequently subjected to subsequent offline maintenance such as cleaning and replacement of parts. In the solution means of the present invention, it is only necessary to separate and remove the spinning unit and the temperature control unit, but it is not necessary to remove the entire spinning unit. Therefore, the range of parts requiring maintenance such as cleaning and replacement is reduced, and the amount of maintenance work such as cleaning and replacement is reduced. Moreover, since the online maintenance time is short and the influence on the spinning production is small, the production efficiency can be improved.

  (2) Next, referring to FIG. 3 to FIG. 4g, another preferred embodiment of the present invention will be described with reference to an example in which the spinning unit includes a metering drive device, a metering device, a connection port conversion unit, a temperature control unit, and a spinning unit. The technical solution of the aspect will be further described. Even in the case of a spinning unit having other structures, the description thereof will be omitted if the embodiments are similar.

The spinning unit 1 includes at least one metering device 11, a connection port conversion unit 12, a temperature control unit 13, a spinning unit 14, and at least one metering drive device 15, and includes a metering device 11, a connection port conversion unit 12, and a temperature control unit. 13. The spinning unit 14 and the metering drive device 15 cannot be changed relative to each other in the up-and-down position, and are stacked in the vertical direction to form an integrated structure. Here, at least the temperature control unit 13 and the spinning unit 14 are detachable. A rotating shaft 16 is provided at both ends of the spinning unit 1 and connected to the moving bracket 2 via the rotating shaft 16, and the entire spinning unit 1 can be rotated by the moving bracket 2. A moving bracket guide portion 21 is provided on each side of the moving bracket 2. The spinning unit 1 can move up and down along the moving bracket guide portion 21, and the moving bracket guide portion 21 can be provided with a plurality of position limiting holes at intervals. By inserting a position limiting component such as the position limiting pin 22 into a position limiting hole having a corresponding height, the position of the spinning unit in the ascending / descending direction can be limited. The rotational movement control unit includes a second lifting drive mechanism 42, a second slide rail 33, and the rotation drive mechanism 6, and the second slide rail 33 is provided along the minor axis direction of the spinning unit 14.

  As shown in FIG. 4a, when the spinning section 1 is in a normal spinning operation state, the spinning unit 14 is provided at the top of the spinning box and communicates with the spinning passage 5, and the spinning unit 14 is facing downward. When the spinning unit 14 needs to be replaced, the spinning production is interrupted.

  As shown in FIG. 4b, the second elevating drive mechanism 42 drives the spinning unit 1 so as to move in the vertical direction and rise to a predetermined position. Further, as shown in FIG. 4 c, in order to limit the position of the spinning unit 1, the position limiting pin 22 is inserted into a position limiting hole opened at a corresponding height of the moving bracket guide unit 21. Next, as shown in FIGS. 4d to 4e, a driving force that horizontally moves along the minor axis direction of the spinning unit is applied to the entire moving bracket 2 and the spinning unit 1 (the driving force can be applied manually, For example, the spinning bracket 1 and the entire spinning unit 1 are moved horizontally along the second slide rail 31 so as to be offset from the spinning path. Thereafter, the rotary drive mechanism 6 such as a manual worm speed reducer outputs power to the rotary shaft 16 to rotate the entire spinning unit with the moving bracket, and the orientation of the spinning unit of the spinning unit rotated by a predetermined angle is easy to maintain. It becomes the direction. For example, as shown in FIGS. 4f to 4g, after a predetermined angle of normal rotation, the spinning unit of the spinning unit faces obliquely upward with respect to the horizontal direction, for example, after 180 ° of normal rotation, the spinning unit of the spinning unit is reversed. Then turn up. In this way, the spinning unit 14 can be removed and replaced with another spinning unit 14.

  After the replacement of the spinning unit 14 is completed, the rotation drive mechanism 6 outputs power to the rotating shaft 16, reversely rotates the entire spinning unit on the moving bracket 2, and the direction of the spinning unit of the spinning unit rotated by a predetermined angle is spinning. It becomes the direction which is easy to spin to the passage 5. For example, after reverse rotation by a predetermined angle, the spinning unit of the spinning section is reversed and turned downward. Also, for example, after 180 degrees reverse rotation, the spinning unit of the spinning section is reversed and turned downward. Next, a driving force that horizontally moves along the minor axis direction of the spinning unit is applied to the entire moving bracket 2 and the spinning unit 1, and the moving bracket 2 and the spinning unit 1 are entirely moved along the second slide rail 33. 1 is horizontally moved to a position where the upper and lower sides of the spinning path coincide with each other. Thereafter, the position limit pin 22 inserted in the position limit hole of the moving bracket guide portion 21 is taken out, and the second lifting drive mechanism 42 moves the moving bracket 2 and the entire spinning portion 1 in the vertical direction and lowers them to the spinning portion 14. Drive to be connected to the spinning passage 5.

  In this way, replacement maintenance of the spinning unit 14 is completed, and spinning production of elastic fibers can be resumed. The removed spinning unit 14 can be subsequently subjected to subsequent offline maintenance, such as cleaning and replacing parts. In this solution, it is only necessary to separate and remove the spinning unit and the temperature control unit, and it is not necessary to remove the entire spinning unit. Therefore, the range of parts requiring maintenance such as cleaning and replacement is reduced, and the amount of maintenance work such as cleaning and replacement is reduced. Moreover, the online maintenance time is short, the influence on the spinning production is small, and the production efficiency can be improved.
