  • the present invention relates to a yarn winding device.
  • a yarn winding device that forms a package by winding on a winding tube a yarn supplied from a yarn supplying section is disclosed in Japanese Patent Application Laid-Open No. 2016-78995 .
  • the disclosed yarn winding device includes a contact roller that rotates while being in contact with the package to rotate the package, and a roller driving source that drives the contact roller. Also, a configuration that directly brakes the rotation of the package is disclosed.
  • the yarn winding device includes a rotary holder that rotates integrally with the winding tube, a package brake that brakes the rotary holder by using a pressure of compressed air, a solenoid valve that switches between supply and no-supply of the compressed air to the package brake, and a controlling unit that opens / closes the solenoid valve.
  • the package brake includes a braking piston that brakes the rotation of the rotary holder and a housing that is a chamber to which the compressed air is supplied. When the compressed air is not supplied, the brake does not operate on the package and the package can rotate freely.
  • the controlling unit controls the solenoid valve to supply the compressed air to the chamber, the braking piston moves and contacts the rotary holder, and the package decelerates by frictional resistance between the braking piston and the rotary holder.
  • Japanese Patent Application Laid-Open No. 2010-37083 discloses a yarn winding device including a package brake, a solenoid valve, and a controlling unit similar to Japanese Patent Application Laid-Open No. 2016-78995 .
  • the controlling unit controls the solenoid valve to alternately repeat supply and exhaust of compressed air.
  • the so-called pumping brake is realized thereby gradually applying a braking force on the package to stop the rotation of the package.
  • a ratio of an open duration and a closed duration of the solenoid valve is constant from a time point at which the package starts decelerating until a time point at which the package stops.
  • DE 10 2009 004615 A1 refers to a method for driving a winding device and a winding device of a textile machine.
  • a pressure inside the chamber can be changed by alternately repeating the supply and no-supply of the compressed air; however, this does not mean that the ratio between the open duration and the closed duration of the solenoid valve is changed during the deceleration of the package. That is, the pressure inside the chamber cannot be changed to a desired value during the deceleration of the package.
  • One object of the present invention is to make it possible to adjust a pressure of fluid supplied to a chamber to a desired value at a given time during deceleration of a package thereby making it possible to change a magnitude of a braking force acting on the package at a given time.
  • the braking device includes a braking member that brakes rotation of the package; a chamber that operates the braking member by a pressure of fluid inside thereof; and a fluid pressure changing section that changes the pressure of the fluid supplied to the chamber.
  • the fluid pressure changing section includes a first valve arranged between the chamber and a fluid supply port connected to a fluid supply source; a second valve arranged between the chamber and a fluid discharge port; and a fluid pressure controlling section that opens and closes the first valve and the second valve independently.
  • the braking device includes a braking member that brakes rotation of the package; a chamber that operates the braking member by a pressure of fluid inside thereof; and a fluid pressure changing section that changes the pressure of the fluid supplied to the chamber.
  • the fluid pressure changing section includes a first valve arranged between the chamber and a fluid supply port connected to a fluid supply source; a second valve arranged between the chamber and a fluid discharge port; and a fluid pressure controlling section that opens and closes the first valve and the second valve independently.
  • the first valve is for supplying the fluid from the fluid supply port to the chamber.
  • the second valve is for discharging the fluid from the chamber to the fluid discharge port.
  • the braking device can further include a pressure detecting section that detects the pressure of the fluid supplied from the fluid pressure changing section to the chamber.
  • the fluid pressure controlling section controls the first valve and the second valve based on the pressure detected by the pressure detecting section so that the pressure of the fluid supplied to the chamber is equal to a designated pressure.
  • the first valve and the second valve are controlled by the fluid pressure controlling section based on the pressure detected by the pressure detecting section such that the pressure of the fluid supplied to the chamber is maintained at the designated pressure. Accordingly, the pressure can be adjusted to the designated pressure, and the braking force acting on the package can be changed.
  • the designated pressure is sequentially input into the fluid pressure controlling section from outside.
  • the designated pressure is input into the fluid pressure controlling section from outside from time to time. That is, the magnitude of the designated pressure can be changed at a given time while the package is decelerating. Accordingly, the magnitude of the braking force acting on the package can be changed appropriately depending on the situation at a given time.
  • the braking device can further include a supply switching valve arranged between the chamber and the first valve of the fluid pressure changing section; and a supply controlling section that controls opening and closing of the supply switching valve.
  • the supply and no-supply of the fluid from the fluid pressure changing section to the chamber can be switched by performing the opening and closing of the supply switching valve.
  • the fluid supplied from the fluid pressure changing section can be supplied to the chamber after changing the pressure thereof. Accordingly, the braking force acting on the package can be changed further finely.
  • the supply controlling section causes the opening and closing of the supply switching valve to be performed repeatedly alternately.
  • the opening and closing of the supply switching valve is performed alternately repeatedly, the supply and no-supply of the fluid to the chamber is performed alternately repeatedly.
  • the pressure of the fluid supplied to the chamber decreases below the pressure of the fluid supplied from the fluid pressure changing section. Accordingly, the braking force can be applied on the package more gradually than when only the fluid pressure changing section is used.
  • the supply controlling section changes at least one between an open duration and a closed duration of the supply switching valve.
  • the pressure of the fluid supplied to the chamber from the fluid pressure changing section can be adjusted. Accordingly, the braking force acting on the package can be changed further finely.
  • the above yarn winding device can further include a contact roller that rotates the package by rotating while being in contact with the package; a roller driving section that rotationally drives the contact roller; a package rotational speed detecting section that detects a rotational speed of the package; a contact roller rotational speed detecting section that detects a rotational speed of the contact roller; and a winding controlling section that controls the braking device and the roller driving section.
  • the winding controlling section when decelerating the package that is in contact with the contact roller while maintaining a state in which the yarn is being wound on the package, controls the braking device and the roller driving section so that a difference in a circumferential speed of the package and a circumferential speed of the contact roller falls within a predetermined range based on a detection result obtained in the package rotational speed detecting section and a detection result obtained in the contact roller rotational speed detecting section.
  • the pressure of the fluid supplied to the chamber can be adjusted to a desired pressure at a given time, and the braking force acting on the package can be changed at a given time, so that the difference in the circumferential speeds of the package and the contact roller can be made small, and various issues can be prevented.
  • the above yarn winding device can further include a yarn accumulating section arranged between the yarn supplying section and the package forming section and that accumulates the yarn supplied from the yarn supplying section; and a yarn joining device arranged between the yarn supplying section and the yarn accumulating section and that joins a yarn end from the yarn supplying section and a yarn end from the yarn accumulating section when the yarn is discontinuous between the yarn supplying section and the yarn accumulating section.
  • the winding controlling section controls the braking device and the roller driving section to decelerate the package and the contact roller while the yarn is being joined by the yarn joining device.
  • the formation of the package is continued by pulling the yarn accumulated in the yarn accumulating section while the yarn joining is performed by the yarn joining device.
  • the yarn joining device When decelerating the package so that the yarn accumulated in the yarn accumulating section does not dry up, while the yarn is continuous between the yarn accumulating section and the package, stitching, outer layer disorder of the package, and the like may occur if the difference in the circumferential speed of the package and the circumferential speed of the contact roller is large.
  • the pressure of the fluid supplied to the chamber can be adjusted to a desired pressure at a given time, and the braking force acting on the package can be changed at a given time, so that the above-mentioned difference in the circumferential speeds can be made small, and various issues can be prevented.
  • the braking device changes the pressure of the fluid supplied to the chamber so that the lesser the amount of the yarn on the package is the weaker a braking force acts on the package.
  • the braking force acting on the package can be made smaller in proportion to the weight of the package. Accordingly, excessive deceleration of the package can be prevented.

Accordingly, the magnitude of the braking force acting on the package 100 can be changed appropriately depending on the situation.
  • the pressure inside the chamber 76 can be controlled to a desired pressure by the braking device 53 according to the present embodiment by changing the pressure of the compressed air supplied from the air pressure changing section 71 to the chamber 76.
  • the braking device 53 when decelerating the package 100, the deceleration can be performed appropriately depending on the situation such as the variations in a circumferential speed of the package 100, thereby allowing prevention of quality degradation of the package 100, for example.
  • a case of performing a deceleration control on the package 100 when performing the yarn joining after occurrence of a yarn breakage and the like is explained below.
  • the winding unit 2 includes the yarn accumulating section 13 so that, when performing the yarn joining, the yarn joining can be performed while continuing the winding of the yarn Y by using the yarn Y accumulated in the yarn accumulating section 13.
  • the yarn joining fails by any chance, because the yarn Y accumulated in the yarn accumulating section 13 may dry up, a control is performed to decelerate the package 100 during the yarn joining thereby suppressing the consumption of the yarn Y in the yarn accumulating section 13.
  • the package 100 is appropriately decelerated without degrading the quality of the package 100 to the utmost by controlling the pressure inside the chamber 76 with the braking device 53.
  • FIGS. 8 and 9 A series of control performed in a deceleration process of the package 100 by the unit controlling section 15 at the time of the occurrence of the yarn breakage and the like is explained below by using FIGS. 8 and 9 .
  • the unit controlling section 15 has driven the drum driving motor 62 to rotate the traversing drum 52 while the package 100 and the traversing drum 52 are in contact with each other whereby some yarn Y has been wound on the package 100. Moreover, the low-pressure compressed air is being supplied to the chamber 76 of the braking cylinder 60 so that the package 100 is not braked. That is, the circumferential speed of the package 100 and a circumferential speed of the traversing drum 52 are almost equal. Moreover, the unit controlling section 15 is controlling the drum driving motor 42 to rotate the yarn accumulating drum 41 to keep an appropriate amount of the accumulated yarn Y in the yarn accumulating section 13. A yarn winding operation performed under these conditions is referred to as a normal winding operation below. In the normal winding operation, the circumferential speeds of the package 100 and the traversing drum 52 are 1500 m/min, for example.
  • the deceleration process of the package 100 and the traversing drum 52 to reduce the winding speed of the yarn Y is performed (S102) so that the yarn Y accumulated in the yarn accumulating section 13 does not dry up.
  • the unit controlling section 15 causes the package 100 and the traversing drum 52 to decelerate thereby temporarily reducing the winding speed of the yarn Y so that the yarn Y accumulated in the yarn accumulating section 13 does not dry up.
  • the unit controlling section 15 reads a target circumferential speed of the traversing drum 52 and controls the drum driving motor 62 to start the deceleration of the traversing drum 52. Simultaneously with this, the unit controlling section 15 reads a designated pressure at the time of start of the deceleration and outputs the designated pressure to the air pressure changing section 71.
  • the air pressure controlling section 83 supplies the compressed air to the chamber 76 based on the input designated pressure, and starts the deceleration of the package 100.
  • the unit controlling section 15 calculates a difference (sliding amount) in the circumferential speed of the package 100 and the circumferential speed of the traversing drum 52 at a given time.
  • the circumferential speed of the traversing drum 52 is calculated based on the detection result obtained in the drum rotational speed sensor 63 and a diameter of the traversing drum 52 previously stored in the ROM and the like.
  • the circumferential speed of the package 100 is controlled based on the detection result obtained in the package rotational speed sensor 61 and the detection result obtained in the drum rotational speed sensor 63.
  • a ratio between the detection result obtained in the package rotational speed sensor 61 and the detection result obtained in the drum rotational speed sensor 63 is calculated. For this ratio, it is assumed that the circumferential speed of the package 100 and the circumferential speed of the traversing drum 52 are equal, and the deceleration control is performed based on this ratio while taking into account the sliding amount.
  • FIGS. 9A and 9B are graphs indicating examples of a temporal variation of the pressure of the compressed air supplied to the chamber 76 after starting the deceleration of the package 100.
  • the initial pressure which is the pressure before the start of the deceleration, is the pressure P0 that is the low pressure mentioned above.
  • the pressure after the deceleration process starts is higher than the pressure P0.
  • the unit controlling section 15 outputs the designated pressure to the air pressure controlling section 83 from time to time and controls the air pressure changing section 71 so that the sliding amount at a given time falls within a predetermined range.
  • the designated pressure is reduced to reduce the deceleration, and if the deceleration of the package 100 is insufficient, the designated pressure is increased to increase the deceleration. Because the pressure is adjusted by the air pressure changing section 71 to a desired pressure that is equal to or lower than the pressure Pmax at a given time, such a control is possible.
  • the magnitude of the designated pressure can change depending on the amount of the yarn on the package 100.
  • the unit controlling section 15 outputs the designated pressure for which the sliding amount falls within the predetermined range. Therefore, if the package 100 is light, the designated pressure is generally relatively low (see FIG. 9A ). In contrast, if the package 100 is heavy, the designated pressure is generally relatively high (see FIG. 9B ). Based on the designated pressure, the air pressure controlling section 83 changes the pressure so that the lesser the amount of the yarn of the package 100 is the weaker the braking force acts on the package 100.
  • the unit controlling section 15 determines whether the winding speed of the yarn Y onto the package 100 has reached a target value. If the circumferential speed of the package 100 has reached the target value, the unit controlling section 15 maintains the circumferential speed. If the circumferential speed of the package 100 has not reached the target value, the deceleration process is continued.
  • the unit controlling section 15 controls the braking device 53 and the drum driving motor 62 so as to stop the package 100 and the traversing drum 52.
  • the unit controlling section 15 performs the yarn joining process.
  • the unit controlling section 15 controls the drum driving motor 42 so as to stop the yarn accumulating drum 41. Thereafter, as mentioned above, the unit controlling section 15 guides the lower yarn Y1 and the upper yarn Y2 to the yarn joining device 33 and controls the yarn joining device 33 to perform the yarn joining. Even while the yarn joining process is being performed, the unit controlling section 15 drives the drum driving motor 62 to rotate the traversing drum 52 and the package 100 whereby the pulling of the yarn Y from the yarn accumulating section 13 and the winding of the yarn Y on the package 100 are continued. However, in this case, the amount of the accumulated yarn Y decreases as the yarn accumulating drum 41 is not rotating.
  • the unit controlling section 15 controls the drum driving motor 42 to rotate the yarn accumulating drum 41 and restarts the accumulation of the yarn Y in the yarn accumulating section 13.
  • the unit controlling section 15 accelerates the yarn accumulating drum 41 to rotate it at a rotational speed that is faster than the same in the normal winding operation (S103).
  • the unit controlling section 15 controls the drum driving motor 62 to accelerate the traversing drum 52 so that the winding speed of the yarn Y is returned to the same in the normal winding operation (S104). On this occasion, the rotational speed of the yarn accumulating drum 41 is also returned to the rotational speed in the normal winding operation.
  • the pressure of the compressed air supplied to the chamber 76 can be adjusted to a desired pressure at a given time, and the braking force acting on the package 100 can be changed at a given time. Therefore, while the package 100 and the traversing drum 52 are in contact with each other, and the package 100 and the traversing drum 52 are to be decelerated in the state in which the yarn is continuous and the yarn Y is being wound, the difference in the circumferential speeds of the package 100 and the traversing drum 52 can be made small by decelerating the traversing drum 52 with maximum efficiency and causing the package 100 to follow. Accordingly, issues such as stitching, yarn breakage, and the like can be prevented.
  • the formation of the package 100 is continued by pulling the yarn Y accumulated in the yarn accumulating section 13 while the yarn joining is performed by the yarn joining device 33.
  • the yarn joining device 33 When decelerating the package 100 so that the yarn accumulated in the yarn accumulating section 13 does not dry up, while the yarn is continuous between the yarn accumulating section 13 and the package 100, stitching, outer layer disorder of the package, and the like may occur if the difference in the circumferential speed of the package 100 and the circumferential speed of the traversing drum 52 is large.
  • the pressure of the compressed air supplied to the chamber 76 can be adjusted to a desired pressure at a given time, and the braking force acting on the package 100 can be changed at a given time, so that the above-mentioned difference in the circumferential speeds can be controlled easily, and various issues can be prevented.
  • the braking force acting on the package 100 can be made smaller in proportion to the weight of the package 100, excessive deceleration of the package 100 can be prevented.
  • the solenoid valve 87 is a normally closed 3-way solenoid valve.
  • the solenoid valve 87 is arranged between the chamber 76 and the supply port 84 and the exhaust port 85.
  • a supply port side of the solenoid valve 87 is connected to the supply port 84.
  • An exhaust port side of the solenoid valve 87 is connected to the exhaust port 85.
  • a cylinder port side of the solenoid valve 87 is connected to the chamber 76.
  • the supply controlling section 88 controls ON / OFF (opening and closing) of the solenoid valve 87.
  • Data relating to opening and closing timings of the solenoid valve 87 is output, for example, from the unit controlling section 15.
  • FIGS. 11A to 11D A temporal variation of the pressure of the compressed air supplied to the chamber 76 during the deceleration process is explained by using FIGS. 11A to 11D .
  • a plurality of sets of setting data relating to the switching timings between opening and closing of the solenoid valve 87 within a certain period is stored in the ROM and the like of the unit controlling section 15.
  • FIG. 11A shows an example of setting data in the form of a graph in which switching between ON / OFF is repeated alternately twice within a period A, and an ON duration (open duration) is shorter than an OFF duration (closed duration).
  • FIG. 11B shows setting data in the form of a graph in which the ON duration is longer than the OFF duration.
  • the ON duration thereof is longer than that of the setting data shown in FIG. 11A , the pressure increases easily.
  • the period A is a short period of the order of, for example, 0.1 second.
  • the setting data is not limited to the above-mentioned data.
  • the ON duration and the OFF duration can be equal.
  • the first ON duration and the second ON duration can be different. The number of times of repetition needs not be two.
  • the unit controlling section 15 calculates a difference in the circumferential speeds of both at a given time, and based on the difference in the circumferential speeds at the current time point, reads the most appropriate setting data relating to the switching timing of ON / OFF of the solenoid valve 87. For example, as shown in FIG. 11C , assume that three sets of the setting data respectively having a different ratio of the ON duration and the OFF duration are read sequentially. When such setting data are input sequentially from the unit controlling section 15 into the supply controlling section 88, the supply controlling section 88 repeats alternately the opening and closing of the solenoid valve 87 while changing the ON duration and the OFF duration based on the setting data.
  • the pressure shows a temporal variation in a range that is equal to or lower than the pressure Pmax as shown in FIG. 11D . Accordingly, although a fine pressure adjustment cannot be performed like when the air pressure changing section 71 is used, unlike in the conventional pumping brake control, a feedback is performed during the deceleration of the package 100 based on the difference in the circumferential speeds and the magnitude of the pressure can be adjusted to a desired magnitude at a given time. Accordingly, the braking force acting on the package 100 can be changed at a given time.
