Definitions

  • the present invention relates to a yarn winder configured to form a package by winding a yarn onto a bobbin.
  • Patent Literature 1 discloses a yarn re-winder which is configured to re-wind a yarn supplied from a yarn supply package to a bobbin so as to form a wound package.
  • the yarn re-winder includes a bobbin holding member (support arm) which is swingable and supports a bobbin to be rotatable, a friction roller which makes contact with a wound package and rotates the wound package, and a motor which rotationally drives the friction roller.
  • the friction roller is rotationally driven, the wound package passively rotates and a yarn is wound onto the wound package (winding operation).
  • the support arm swings as the diameter of the wound package increases.
  • the wound package may vibrate due to reasons such as deformation of the wound package (i.e., slight deviation from the optimal shape) . Such vibration may cause further deformation of the rotating wound package, and this may result in collapse in shape of the wound package.
  • a vibration suppression mechanism shown in Patent Literature 2 may be provided in the above-described yarn re-winder.
  • the vibration suppression mechanism includes a brake piece attached to a support arm, a brake body pressed onto the brake piece, and a spring biasing the brake body. With this arrangement, the vibration of the support arm is suppressed by friction force acting between the brake piece and the brake body, and hence the vibration of the package is suppressed.
  • the biasing force of the spring is not actively changed in the winding operation.
  • the biasing force of the spring is set large in advance in order to ensure the suppression of vibration, the above-described friction force may become too large.
  • the friction force is too large, the swing of the support arm in accordance with the increase in diameter of the wound package may not be smoothly performed.
  • the biasing force is set small in advance in order to ensure smooth swing of the support arm, the friction force may become too small. When the friction force is too small, the vibration of the wound package may not be sufficiently suppressed.
  • the biasing force required for sufficiently suppressing the vibration of the wound package is significantly larger than the biasing force which is sufficient to allow the support arm to smoothly swing, it may be impossible to achieve both the smooth swing of the support arm and the suppression of the vibration of the wound package.
  • An object of the present invention is to achieve both smooth movement of a support arm and suppression of vibration of a package.
  • a yarn winder of a first aspect of the invention is defined in claim 1.
  • the vibration suppression member As the vibration suppression member is pressed onto the support arm by the pressing mechanism, friction force acts between the vibration suppression member and the support arm. This friction force suppresses the vibration of the support arm, with the result that the vibration of the package is suppressed. Furthermore, the pressing mechanism is able to change the magnitude of the pressing force during the winding operation. In other words, the friction force is changeable during the winding operation. Therefore, when the support arm is moved in the predetermined direction, the support arm can be smoothly moved in a reliable manner as the friction force is decreased. Meanwhile, when the vibration of the package is suppressed, the suppression of the vibration of the support arm is ensured as the friction force is increased. As such, both the smooth movement of the support arm and the suppression of the vibration of the package are achieved.
  • the yarn winder of the first aspect is arranged such that the pressing mechanism includes a fluid pressure cylinder which changes the magnitude of the pressing force in accordance with t pressure of supplied fluid.
  • the pressing mechanism for example, a typical ball-screw mechanism or an electric actuator may be used. These mechanisms, however, essentially change the position of an object rather than the magnitude of pressing force. For this reason, it may be difficult to precisely control the magnitude of the pressing force by these mechanisms. Furthermore, the above-described mechanisms are typically unlikely to absorb vibration. That is to say, when, for example, the support arm slightly vibrates and the vibration is propagated to the vibration suppression member, repulsion to the vibration by the pressing mechanism tends to occur. This may cause the pressing force to be unstable. According to the aspect, the magnitude of the pressing force can be changed by changing the pressure of the supplied fluid. Furthermore, because the hydrostatic pressure cylinder typically has a cushioning property, even if the vibration suppression member vibrates, the vibration is absorbed and a change in the pressing force is suppressed. It is therefore possible to suppress the pressing force from becoming unstable.
  • the yarn winder of the first or second aspect further includes a contact pressure applying roller which applies contact pressure to the package which is rotating, the contact pressure applying roller being movable in accordance with a change in diameter of the package.
  • the package rotates in such a way that its surface is along the surface of the contact pressure applying roller.
  • the hardness (density) of the package significant vibration may occur even if the package is only slightly deformed from the optimal shape.
  • the pressing force is changeable, with the result that smooth movement of the support arm and suppression of vibration of the package are both achieved.
  • the movement of the support arm and the movement of the contact pressure applying roller may be unstable, and such instability may cause the package to easily vibrate.
  • the magnitude of the pressing force is changeable during the winding operation, even if the movement of the support arm or the movement of the contact pressure applying roller becomes unstable, the vibration of the package is reliably suppressed by increasing the pressing force.
  • the yarn winder of the third aspect further includes a biasing mechanism which is configured to bias the contact pressure applying roller toward the package.
  • the gravity acting on the package may influence on the magnitude of the contact pressure in addition to the biasing force, depending on the positional relationship between the package and the contact pressure applying roller.
  • the contact pressure may not be easily controllable.
  • the contact pressure applying roller is biased toward the package, the magnitude of the contact pressure is maintained to be constant by maintaining the biasing force to be constant, irrespective of the weight of the package. In other words, it is unnecessary to take into account of a change in weight of the package. The contact pressure is therefore easily controllable.
  • the yarn winder of the third or fourth aspect further includes: a tension applying mechanism which is configured to apply tension to the yarn wound onto the package and is capable of changing the magnitude of the tension; and a contact pressure changing mechanism which is capable of changing the magnitude of the contact pressure.
  • the density (hardness) of the package is also high.
  • the magnitude of the tension and the magnitude of the contact pressure are changeable as in the aspect, it is possible to wind the yarn with desired density.
  • the package rotates with its surface being along the surface of the contact pressure applying roller.
  • the hardness (density) of the package is increased, significant vibration may occur even when the package is only slightly deformed from the optimal shape.
  • the pressing force is changeable during the winding operation, with the result that smooth movement of the support arm and suppression of vibration of the package are both achieved.
  • the yarn winder of any one of the first to fifth aspects is arranged such that a contact surface of the vibration suppression member, where the vibration suppression member makes contact with the support arm, extends along the predetermined direction.
  • the support arm When the contact surface is tilted with respect to the predetermined direction (moving direction of the support arm), the support arm may be pressed in the predetermined direction by the vibration suppression member, and hence the support arm may, for example, unintentionally move in the predetermined direction.
  • the contact surface extends along the predetermined direction, it is possible to avoid the pressing of the support arm in the predetermined direction by, for example, pressing the vibration suppression member in the direction perpendicular to the contact surface. Therefore, for example, unintentional movement of the support arm in the predetermined direction is avoided.
  • the yarn winder of any one of the first to sixth aspects is arranged such that the vibration suppression member is rotatable about a rotation fulcrum which is fixed to a predetermined position.
  • the vibration suppression member can be strongly and stably pressed onto the support arm.
  • the yarn winder of any one of the first to seventh aspects is arranged such that the cradle device includes an arm driving unit which is configured to move the support arm in the predetermined direction.
  • the support arm when the support arm is moved by the arm driving unit, the support arm can be smoothly moved as the pressing force is decreased (i.e., the friction force is decreased) . Meanwhile, when the support arm is not moved, it is possible to increase the pressing force (i.e., increase the friction force) without any problems. On this account, it is possible to reliably suppress the vibration of the support arm by increasing the pressing force. As such, by changing the magnitude of the pressing force in accordance with the operation of the arm driving unit, it is possible to effectively achieve both the smooth movement of the support arm and the suppression of the vibration of the package.
  • the yarn winder of any one of the first to eighth aspects may be arranged such that the support arm includes: an arm main body; and a contact target roller which is supported by the arm main body to be rotatable, the vibration suppression member making contact with the contact target roller.
  • the friction force may be too large and the movement of the support arm may not be smoothly done. Then, it is possible to facilitate smooth movement of the support arm by the rotatable contact target roller.
  • the yarn winder of any one of the first to eighth aspects is arranged such that the support arm is swingable about a swing fulcrum fixed to a predetermined position.
  • the traveling range of the support arm is short at around the swing fulcrum, as compared to the arrangement in which the support arm moves in a parallel manner. It is therefore possible to avoid the increase in size of the device.
  • the yarn winder further includes a control unit, during the winding operation, the control unit changing the magnitude of the pressing force between first pressing force and second pressing force which is smaller than the first pressing force.
  • the friction force is maintained to be large by pressing the vibration suppression member onto the support arm by the relatively large first pressing force, with the result that the vibration of the package is suppressed.
  • the pressing force is decreased to the second pressing force at predetermined intervals, with the result that the friction force is temporarily decreased and the support arm is allowed to reliably move in the predetermined direction.
  • the vibration of the package is reliably suppressed in the normal state, and the support arm is allowed to smoothly move in a reliable manner when the support arm moves.
  • the yarn winder further includes an arm driving unit which is configured to move the support arm in the predetermined direction, the control unit setting the magnitude of the pressing force at the first pressing force when the arm driving unit is not driven, and setting the magnitude of the pressing force at the second pressing force when the arm driving unit is driven.
  • the yarn winder of any one of the first to ninth aspects further includes a package diameter detection unit which is configured to detect a change in diameter of the package, the control unit controlling the arm driving unit based on a detection result of the package diameter detection unit.
  • the support arm it is possible to allow the support arm to suitably move in accordance with a change in diameter of the package.
  • the yarn winder of any one of the first to tenth aspect further includes a storage unit which stores a pattern regarding a change over time of the pressing force in advance, the control unit reading the patter before the start of the winding operation.
  • the yarn winder of any one of the first to eleventh aspects further includes: a vibration detection unit which is configured to detect vibration of the package; when the magnitude of the vibration of the package detected by the vibration detection unit is larger than a predetermined threshold, the control unit increasing the pressing force as compared to a case where the magnitude of the vibration is smaller than the threshold.
  • the pressing force is relatively small (i.e., the friction force is relatively small) when the magnitude of the vibration of the package is equal to or lower than a predetermined level, smooth movement of the support arm is facilitated.
  • the pressing force is relatively large (i.e., the friction force is relatively large) when the magnitude of the vibration of the package is equal to or higher than the predetermined level, suppression of the vibration of the package is facilitated.

In such a state, smooth swing of the cradle arm 31 and suppression of the vibration of the wound package Pw may not be concurrently achieved. Under this circumstance, in the present embodiment, the pressing mechanism 61 is arranged as described below, in order to concurrently achieve the smooth swing of the cradle arm 31 and the suppression of the vibration of the wound package Pw.
  • the pressing mechanism 61 includes, for example, an air cylinder 62 (fluid pressure cylinder of the present invention) and an electro-pneumatic regulator 63.
  • the air cylinder 62 is, for example, a typical pull-type cylinder.
  • the air cylinder 62 is attached to the base 14.
  • a leading end portion of a piston rod 64 of the air cylinder 62 is connected to an end portion of the vibration suppression lever 41.
  • the junction between the vibration suppression lever 41 and the piston rod 64 is provided to oppose a part where the contact surface 43 is formed, over the rotation fulcrum 42.
  • the disclosure is not limited to this arrangement.
  • the air cylinder 62 is connected, through pipes, to a supply port (not illustrated) connected to a source of compressed air and an exhaust port (not illustrated) through which air is discharged.
  • the air cylinder 62 typically has a cushioning property. On this account, even if the vibration suppression lever 41 vibrates, the vibration is absorbed and a change in the pressing force is suppressed.
  • the electro-pneumatic regulator 63 is provided between the supply and discharge ports and the air cylinder 62.
  • the electro-pneumatic regulator 63 includes plural electromagnetic valves, a pressure gauge, and a controller and is arranged to be able to adjust the pressure of compressed air supplied to the air cylinder 62.
  • the electro-pneumatic regulator 63 is electrically connected to the controller 13 (see FIG. 3 ).
  • the compressed air with pressure adjusted by the electro-pneumatic regulator 63 is supplied to the air cylinder 62 through a supply tube 65.
  • the vibration suppression lever 41 is pulled by the piston rod 64 (as indicated by an arrow 104 in FIG. 2 ) and the contact surface 43 is pressed onto the contact target roller 34.
  • the magnitude of the pressing force is changed in accordance with the pressure of compressed air supplied to the air cylinder 62.
  • the pressing force increases as the pressure of the supplied compressed air increases.
  • the pressing mechanism 61 is able to change the magnitude of the pressing force during the winding operation of winding the yarn Y.
  • FIG. 5 is a graph showing variations over time of an operation of the arm driving motor 37 during the winding operation, the pressure of compressed air supplied to the air cylinder 62, and an angle of the cradle arm 31.
  • the winding operation is performed such that the controller 13 rotationally drives the winding motor 32 to wind the yarn Y into the bobbin B.
  • the time point t is t0 (see FIG. 4(a) and FIG. 5 ).
  • the arm driving motor 37 is on standby (OFF in FIG. 5 ) and the cradle arm 31 is on standby at a predetermined position.
  • the pressure of compressed air supplied to the air cylinder 62 is at a constant value (P1) (see FIG. 5 ), and the vibration suppression lever 41 is pressed onto the contact target roller 34 with predetermined first pressing force.
  • the yarn Y is wound onto the bobbin B and the wound package Pw increases in diameter as described above, and the contact roller 22 swings.
  • a detection signal is sent to the controller 13.
  • the time point t is t1 at this stage (see FIG. 4 (b) and FIG. 5 ).
  • the controller 13 drives the arm driving motor 37 (ON in FIG. 5 ) to swing the cradle arm 31.
  • the controller 13 controls the electro-pneumatic regulator 63 (see FIG. 2 ) to lower the pressure of the compressed air supplied to the air cylinder 62 from P1 to P2 ( ⁇ P1) (see FIG. 5 ).
  • the magnitude of the pressing force is changed to second pressing force which is smaller than the first pressing force.
  • the magnitude of the pressing force exerted by the pressing mechanism 61 is changed during the winding operation of winding the yarn Y. Consequently, the friction force acting between the vibration suppression lever 41 and the contact target roller 34 is temporarily decreased, with the result that the cradle arm 31 smoothly swings.
  • the controller 13 stops the arm driving motor 37 (see FIG. 4(c) and FIG. 5 ).
  • the time point t is t2.
  • the controller 13 controls the electro-pneumatic regulator 63 to return the pressure of the compressed air supplied to the air cylinder 62 from P2 to P1.
  • the controller 13 controls the pressing mechanism 61 to change the magnitude of the pressing force between the first pressing force and the second pressing force.
  • the vibration suppression lever 41 As described above, as the vibration suppression lever 41 is pressed onto the cradle arm 31 by the pressing mechanism 61, friction force acts between the vibration suppression lever 41 and the cradle arm 31. This friction force suppresses the vibration of the cradle arm 31, with the result that the vibration of the wound package Pw is suppressed. Furthermore, the pressing mechanism 61 is able to change the magnitude of the pressing force during the winding operation. In other words, the friction force is changeable during the winding operation. Therefore, when the cradle arm 31 is moved in the predetermined direction, the cradle arm 31 can be smoothly moved in a reliable manner as the friction force is decreased.
  • the pressing mechanism 61 includes the air cylinder 62, the magnitude of the pressing force can be changed by changing the supply pressure of the compressed air. Furthermore, because the air cylinder 62 typically has a cushioning property, even if the vibration suppression lever 41 vibrates, the vibration is absorbed and a change in the pressing force is suppressed. It is therefore possible to suppress the pressing force from becoming unstable.
  • the wound package Pw rotates in such a way that its surface is along the surface of the contact roller 22.
  • the hardness (density) of the wound package Pw significant vibration may occur even when the wound package Pw is only slightly deformed from the optimal shape.
  • changeable pressing force and coexistence of smooth movement of the cradle arm 31 and suppression of vibration of the wound package Pw are effective.
  • the movement of the cradle arm 31 and the movement of the contact roller 22 may be unstable, and such instability may cause the wound package Pw to easily vibrate.
  • the magnitude of the pressing force is changeable during the winding operation, even if the movement of the cradle arm 31 or the movement of the contact roller 22 becomes unstable, the vibration of the wound package Pw is reliably suppressed by increasing the pressing force.
  • the contact roller 22 is biased toward the wound package Pw, the magnitude of the contact pressure is maintained to be constant by maintaining the biasing force to be constant, irrespective of the weight of the wound package Pw. In other words, it is unnecessary to take into account of a change in weight of the wound package Pw.
  • the contact pressure is therefore easily controllable.
  • the contact surface 43 of the vibration suppression lever 41 extends along the predetermined direction, it is possible to avoid the pressing of the cradle arm 31 in the predetermined direction by, for example, pressing the vibration suppression lever 41 in the direction perpendicular to the contact surface 43. Therefore, for example, unintentional movement of the cradle arm 31 in the predetermined direction is avoided.
  • the vibration suppression lever 41 is rotatable about the rotation fulcrum 42. Therefore, by utilizing the principle of leverage, the vibration suppression lever 41 can be strongly and stably pressed onto the cradle arm 31.
  • the cradle arm 31 when the cradle arm 31 is moved by the arm driving motor 37, the cradle arm 31 can be smoothly moved as the pressing force is decreased (i.e., the friction force is decreased) . Meanwhile, when the cradle arm 31 is not moved, it is possible to increase the pressing force (i.e., increase the friction force) without any problems. On this account, it is possible to reliably suppress the vibration of the cradle arm 31 by increasing the pressing force. As such, by changing the magnitude of the pressing force in accordance with the operation of the arm driving motor 37, it is possible to effectively achieve both the smooth movement of the cradle arm 31 and the suppression of the vibration of the wound package Pw.
  • the cradle arm 31 is swingable about the swing fulcrum 35.
  • the traveling range of the cradle arm 31 is therefore short at around the swing fulcrum. It is therefore possible to suppress, for example, the apparatus from being upsized, as compared to an arrangement in which the cradle arm 31 is moved in a parallel manner.
  • the controller 13 changes the magnitude of the pressing force between the first pressing force and the second pressing force.
  • the vibration suppression lever 41 is pressed onto the cradle arm 31 with relatively large first pressing force, and hence the friction force is maintained to be large.
  • the vibration of the wound package Pw is therefore suppressed.
  • the pressing force is temporarily decreased to the second pressing force, with the result that the friction force is temporarily decreased and the cradle arm 31 is allowed to reliably swing in the predetermined direction.
  • the vibration of the wound package Pw is reliably suppressed in the normal state, and the cradle arm 31 is allowed to smoothly move in a reliable manner when the cradle arm 31 swings. As such, both the smooth movement of the cradle arm 31 and the suppression of the vibration of the wound package Pw are effectively achieved.
  • the controller 13 controls the operation of the arm driving motor 37 based on a detection result of the proximity sensor 56. It is therefore possible to allow the cradle arm 31 to suitably swing in accordance with a change in diameter of the wound package Pw.
  • Control performed by the controller 13 in the re-winder 1a arranged as described above will be described with reference to a graph in FIG. 7 .
  • the controller 13 changes the pressure of compressed air supplied to the air cylinder 62 between P1 and P2 in the same manner as in the embodiment above.
  • the controller 13 controls the electro-pneumatic regulator 63 to arrange the pressure of the compressed air supplied to the air cylinder 62 to be P3 which is higher than P1.
  • the above-described pressing force is arranged to be large as compared to a case where the magnitude of the vibration is smaller than the threshold.
  • the controller 13 decreases the pressure of the compressed air again.
  • the controller 13 may perform control described below.
  • the storage unit 18 may store a pattern (see FIG. 10 ) regarding variations over time of the pressure of compressed air supplied to the air cylinder 62 in advance.
  • this pattern is a pattern regarding variations over time of the pressure from the start to the end of formation of the wound package Pw.
  • the controller 13 may read the pattern from the storage unit 18 before the start of the winding operation, and change the pressing force over time in accordance with the pattern. As such, both the smooth movement of the cradle arm 31 and the suppression of the vibration of the wound package Pw are achieved by the simple control.
