Definitions

  • the present invention relates to a yarn winding apparatus that winds a yarn to form a package.
  • Japanese Patent Application Laid-open No. 2007-100235 discloses an automatic winder having multiple winding units.
  • a winding unit unwinds a yarn from a supply bobbin and winds the yarn around a winding tube, which is supported by a cradle, while traversing the yarn by a traverse drum, thereby forming a package.
  • the automatic winder disclosed in Japanese Patent Application Laid-open No. 2007-100235 performs the following processes to suppress variation in the weights of the finished packages.
  • a doffing apparatus is moved to the winding unit that has finished the winding of the package to remove from the cradle the package into which the specific amount of yarn has been wound.
  • a weight measuring device included in the doffing apparatus measures the weight of the package into which the specific amount of yarn has been wound. Based on a difference between the measured weight and the reference weight value, the total number of rotations, which corresponds to the predetermined reference weight value, is corrected. This corrected total number of rotations is used for judgment on completion of the winding into the next package on this winding unit.
  • the thickness of yarn that is wound around the winding tube is not uniform.
  • the thickness of the yarn can vary from one supply bobbin to another due to, for example, sources on the side of a spinning machine that produces supply bobbins.
  • the thickness of yarn significantly changes before and after replacement of the supply bobbin.
  • the thickness of the yarn can also vary within a supply bobbin. For this reason, as disclosed in Japanese Patent Application Laid-open No.
  • a yarn winding apparatus includes a yarn supplying section that supplies a yarn; a winding section that winds the yarn supplied from the yarn supplying section to form a package; a yarn thickness detecting section that detects thickness of the yarn that is being wound into the package; a yarn length detecting section that detects a length of the yarn that has been wound into the package; a yarn specific gravity storage section that stores therein information on a specific gravity of the yarn; and a weight calculating section that calculates, based on the thickness of the yarn detected by the yarn thickness detecting section, the length of the yarn detected by the yarn length detecting section, and the information on the specific gravity stored in the yarn specific gravity storage section, a yarn weight of the package formed by the winding section.
  • FIG. 1 is a front view of the automatic winder according to the present embodiment
  • FIG. 2 is a front view of a winding unit in the automatic winder.
  • an automatic winder 1 (yarn winding apparatus) includes multiple winding units 2 that are aligned horizontally as shown in FIG. 1 , a doffing apparatus 3 movable along the arrangement direction of the winding units 2, and a main controller 4 that controls the entire automatic winder 1.
  • the main controller 4 is arranged at one end of the arrangement direction of the winding units 2.
  • This automatic winder 1 has a structure in which the main controller 4 issues commands to each of the winding units 2 so that each of the winding units 2 winds a yarn Y, which is unwound from a supply bobbin B, around a winding tube 17 (see FIG. 2 ) to form a package P.
  • the doffing apparatus 3 moves to a position above this winding unit 2 to replace the finished package P with an empty winding tube 17 around which no yarn is yet wound.
  • the main controller 4 controls the operation of each of the winding units 2, monitors their operational states, and stores therein operation parameter settings and the like.
  • a winding unit 2 The structure of a winding unit 2 is explained in detail below. As shown in FIG. 2 , the winding unit 2 unwinds the yarn Y from the supply bobbin B and winds the unwound yarn Y around the winding tube 17 while traversing the yarn Y to form a package P of a predetermined shape.
  • the winding unit 2 includes a supporting frame 10, a yarn supplying section 11 that unwinds the yarn Y from the supply bobbin B and supplies the yarn Y, a yarn processing section 12 that performs various processes on the yarn Y supplied from the yarn supplying section 11, and a winding section 13 that winds the yarn Y processed by the yarn processing section 12 around the winding tube 17 to form the package P.
  • the supporting frame 10 houses an operation panel 25 having a display unit, operation buttons, and the like, and a unit controller 26 (see FIG. 3 ).
  • the yarn supplying section 11, the yarn processing section 12, and the winding section 13 are arranged from below upwards in this order.
  • the yarn supplying section 11 includes a peg 15 that holds a supply bobbin B in a replaceable manner, and an unwinding assisting device 16 that assists unwinding of the yarn Y from the supply bobbin B.
  • the peg 15 stands in a vertical direction as shown in FIG. 2 when the yarn Y is being unwound (i.e., when the yarn Y is being wound).
  • the peg 15 tilts forward or backward (in a vertical direction with respect to the sheet of FIG. 2 ) to discharge the empty supply bobbin B having no more yarn and receive a new supply bobbin B from a magazine (not shown).
  • the unwinding assisting device 16 has a cylinder that is driven to move up and down above the supply bobbin B by an unwinding assisting device driving section 29 (see FIG. 3 ). This cylinder is moved downward as unwinding of the yarn Y from the supply bobbin B progresses so that the yarn Y can be prevented from being swollen (ballooned) while being unwound and can be stably unwound.
  • the winding section 13 includes a cradle (not shown) that rotatably holds the winding tube 17, and a traverse drum 18 that is driven to rotate by a drum driving section 27 (see FIG. 3 ).
  • the traverse drum 18 has a spiral traverse groove 18a formed on its periphery. The yarn Y is traversed along this traverse groove 18a.
  • the traverse drum 18 is driven to rotate in contact with the package P formed around the winding tube 17 while traversing the yarn Y along the traverse groove 18a.
  • the package P rotates by contact friction with the traverse drum 18, and the yarn Y unwound from the supply bobbin B is thereby wound around the winding tube 17.
  • the yarn processing section 12 includes a yarn feeler 19, a tension applying device 20, a yarn joining device 21, and a yarn clearer 22 (yarn monitoring section).
  • the yarn feeler 19 detects presence or absence of the yarn Y between the unwinding assisting device 16 and the tension applying device 20.
  • the tension applying device 20 applies a predetermined tension to the running yarn Y.
  • a gate type tension applying device that includes fixed comb teeth 20a and movable comb teeth 20b driven by a tension applying device driving section 30 (see FIG. 3 ) is shown as an example of the tension applying device 20.
  • the yarn joining device 21 joins a lower yarn Y1 on the supply bobbin B side and an upper yarn Y2 on the package P side when the yarn Y is cut by a cutter 22a due to a yarn defect detected by the yarn clearer 22, which will be explained later, when the yarn Y runs out while being wound, or when the supply bobbin B is replaced with a new one.
  • An air splicer for example, can be used as the yarn joining device 21. The air splicer generates an airflow to entangle fibers of the lower yarn Y1 and the upper yarn Y2 and joins the lower yarn Y1 and the upper yarn Y2.
  • a lower yarn catching and guiding section 23 that catches the lower yarn Y1 on the supply bobbin B side and guides it to the yarn joining device 21 is arranged below and an upper yarn catching and guiding section 24 that catches the upper yarn Y2 on the package P side and guides it to the yarn joining device 21 is arranged above the yarn joining device 21.
  • An end of the lower yarn catching and guiding section 23 and an end of the upper yarn catching and guiding section 24 are both rotatably supported by the supporting frame 10.
  • the lower yarn catching and guiding section 23 is driven by a lower yarn guiding member driving section 31 and the upper yarn catching and guiding section 24 is driven by an upper yarn guiding member driving section 32 to pivot upward and downward (see FIG. 3 ).
  • a suction vent 23a of the lower yarn catching and guiding section 23 suctions and catches the end of the lower yarn Y1, and pivots upward to guide the lower yarn Y1 to the yarn joining device 21.
  • a suction mouth 24a of the upper yarn catching and guiding section 24 pivots to a yarn end catching position near a contact position of the package P and the traverse drum 18, pivots back downward after suctioning and catching the end of the upper yarn Y2 from the package P at this yarn end catching position, and guides the upper yarn Y2 to the yarn joining device 21.
  • the yarn joining device 21 joins the end of the lower yarn Y1 guided by the lower yarn catching and guiding section 23 and the end of the upper yarn Y2 guided by the upper yarn catching and guiding section 24 into one yarn Y. Consequently, the winding section 13 can resume the winding of the yarn Y.
  • the yarn clearer 22 continuously acquires information on the thickness of the running yarn Y. That is, the yarn clearer 22 corresponds to a yarn thickness detecting section according to the present invention. The yarn clearer 22 also detects, based on the information of the yarn thickness, an abnormal portion of the yarn Y in which the yarn thickness is greater than a predetermined value, as a yarn defect.
  • the cutter 22a is coupled to the yarn clearer 22. The cutter 22a immediately cuts the yarn Y when the yarn clearer 22 detects a yarn defect.
  • the yarn defect When the yarn Y is cut by the yarn clearer 22 in response to detection of a yarn defect, the yarn defect still remains in the upper yarn Y2. Therefore, the yarn defect is removed from the upper yarn Y2, and the lower yarn Y1 and the upper yarn Y2 are joined together in the yarn joining device 21.
  • FIG. 3 is a schematic block diagram of an electrical structure of the automatic winder 1.
  • the main controller 4 of the automatic winder 1 is connected individually to the unit controllers 26 of the winding units 2 and the controller 35 of the doffing apparatus 3 in a communicable manner.
  • the main controller 4 monitors the operational state of each winding unit 2 and also the operational state of the doffing apparatus 3.
  • the main controller 4 stores therein winding conditions of the winding units 2 that perform the winding operation.
  • the winding conditions at least include information on a type of yarn and set values for a yarn length and a yarn weight of the package P.
  • the unit controller 26 includes a central processing unit (CPU) that is a computing device, a read-only memory (ROM) that stores therein computer programs executed by the CPU and data used in the computer programs, a random access memory (RAM) that temporarily stores therein data at the time of executing the computer programs, and the like.
  • CPU central processing unit
  • ROM read-only memory
  • RAM random access memory
  • the unit controller 26 is electrically connected to each of the peg driving section 28, the unwinding assisting device driving section 29, the yarn feeler 19, the tension applying device driving section 30, the yarn joining device 21, the lower yarn guiding member driving section 31, the yarn clearer 22, the upper yarn guiding member driving section 32, the drum driving section 27, and the operation panel 25.
  • the unit controller 26 controls the sections of the winding unit 2 by executing the control computer program stored in the ROM at the CPU based on the winding conditions input from the main controller 4 so that the winding unit 2 executes the predetermined yarn winding operation.
  • the unit controller 26 also communicates with the controller 35 of the doffing apparatus 3, and outputs a signal to instruct the doffing apparatus 3 to perform the doffing operation when formation of the package P is completed.
  • the unit controller 26 also includes a winding controller 40 that controls the drum driving section 27 and thereby controls the winding operation of the winding section 13 (traverse drum 18).
  • the winding controller 40 has a function to selectively execute one of two winding modes: a first winding mode and a second winding mode.
  • the winding modes are different from each other in their methods of managing a yarn amount of a package P.
  • the winding controller 40 determines that a specific amount of yarn (the yarn length or the yarn weight that is determined by the operator in advance to produce packages P) has been wound into the package P and terminates the winding.
  • the first winding mode is what is called a weight-management winding mode, in which the amount of yarn wound into a package P is managed in accordance with the yarn weight.
  • the second winding mode when the yarn length in the package P reaches a set value, the winding controller 40 determines that a specific amount of yarn has been wound into the package P and terminates the winding.
  • the second winding mode is what is called a length-management winding mode, in which the amount of yarn wound into a package P is managed in accordance with the yarn length.
  • management information that indicates whether packages P should be produced by the winding units 2 in accordance with the weight management or the length management is set as one of the winding conditions on the main controller 4 of the automatic winder 1.
  • the winding section 13 of each winding unit 2 receives the management information from this main controller 4, and the winding controller 40 selects an appropriate winding mode based on the received management information.
  • the unit controller 26 includes a yarn length calculating section 41 (yarn length detecting section) that calculates the length of the yarn wound around the winding tube 17 and a weight calculating section 42 that calculates the weight of the package P.
  • the yarn length calculating section 41 counts the total number of rotations of the traverse drum 18 driven by the drum driving section 27 to rotate from the beginning of the winding of the package P, and calculates the length of the yarn Y of the package P that has been wound around the winding tube 17 based on the total number of rotations.
  • the weight calculating section 42 first acquires the information on the thickness of the yarn Y from the yarn clearer 22.
  • the weight calculating section 42 calculates (estimates), based on the information on the yarn thickness acquired from the yarn clearer 22, the yarn length calculated by the yarn length calculating section 41, and the specific gravity of the yarn Y acquired from the main controller 4, the yarn weight of the package P at the current moment.
  • a storage section 50 of the main controller 4 that stores therein the specific gravity of the yarn Y corresponds to a yarn specific gravity storage section according to the present invention.
  • the yarn clearer 22 which serves as a yarn monitoring section, detects the thickness of the yarn Y continuously during the winding so as not to miss any yarn defect because a yarn defect needs to be detected throughout the entire length of the yarn Y unwound from the supply bobbin B.
  • the information on the thickness of the yarn Y does not need to be acquired continuously (in real time). The continuously acquired information on the yarn thickness would only complicate the calculation and require a large capacity for the temporary memory.
  • the weight calculating section 42 therefore acquires the information on the yarn thickness intermittently (periodically) from the yarn clearer 22 that continuously detects the thickness of the yarn Y.
  • the thickness of the yarn Y can significantly vary from one supply bobbin B to another due to sources, for example, on the side of the spinning machine that produces the supply bobbins B. If there is variation in the thickness of the yarn Y among the supply bobbins B, it is preferable that the weight calculating section 42 acquires information on the yarn thickness from the yarn clearer 22 immediately after replacing the supply bobbin B with a new one and resuming the winding.
  • the information on the yarn thickness can also be acquired at the timing of suspending the winding.
  • a yarn joining operation is performed by the yarn joining device 21 not only when the supply bobbin B is replaced but also when the yarn breaks or when the yarn is cut in response to detection of a yarn defect.
  • the weight calculating section 42 can acquire the information on the yarn thickness from the yarn clearer 22 immediately after this yarn joining operation is completed and the winding is resumed. Alternatively, the weight calculating section 42 can acquire the thickness of the yarn Y every time a predetermined period of time elapses from the last acquisition.
  • the weight calculating section 42 obtains a typical value of the yarn thickness, for example, by calculating a simple average of the pieces of information on the yarn thickness, and uses this typical value for the calculation of the yarn weight.
  • a typical value can be calculated by multiplying each of the pieces of the information on the yarn thickness by a weighting factor and then averaging the resultant values (weighted mean).
  • this weighted mean an example of information acquisition on the yarn thickness at the timing of replacing the supply bobbin B is described below.
  • the winding controller 40 selects the winding mode based on the management information received from the main controller 4 (Step S10).
  • the yarn length calculating section 41 keeps calculating the length of the yarn Y package P during the winding (Step S12).
  • the weight calculating section 42 calculates the yarn weight of the package P based on the information on the yarn thickness periodically acquired from the yarn clearer 22, the information on the yarn length calculated by the yarn length calculating section 41, and the specific gravity of the yarn Y (Step S13). The winding of the yarn Y is continued until the calculated yarn weight reaches a set weight value that is input from the main controller 4.
  • the winding controller 40 judges that formation of the package P of the set weight is completed and causes the winding section 13 to terminate the winding of the yarn Y (Step S15).
  • the unit controller 26 further sends a signal to the controller 35 of the doffing apparatus 3 to notify that formation of the package P is completed.
  • the doffing apparatus 3 moves to a position above this winding unit 2 and executes a doffing operation (Step S16). That is, the doffing apparatus removes the finished package P from the cradle of the winding section 13 and mounts an empty winding tube 17 onto the cradle.
  • the yarn length calculating section 41 also keeps calculating the length of the yarn Y of the package P (Step S22). Unlike in the first winding mode, the weight calculating section 42 does not calculate the yarn weight of the package P.
  • the winding of the yarn Y is continued until the yarn length of the package P calculated by the yarn length calculating section 41 reaches a set yarn length value input from the main controller 4.
  • the winding controller 40 judges that formation of the package P of the set yarn length is completed and causes the winding section 13 to terminate the winding (Step S24). Thereafter, the doffing apparatus 3 performs the doffing operation (Step S25).
  • the yarn clearer 22 detects the thickness of the yarn Y that is to be wound, and the yarn length calculating section 41 calculates the length of the yarn Y that has been wound around the winding tube 17 up to the current moment. Consequently, the yarn weight of the package P that has been wound around the winding tube 17 up to the current moment can be accurately calculated based on the information on the yarn thickness and the yarn length, and also by using the information on the specific gravity of the yarn Y.
  • the winding of the package P is stopped. In this manner, packages P having a minimized difference in weight with respect to the set weight value can be formed, and the management of the packages P having a uniform weight can be realized.
  • a yarn winding apparatus includes a yarn supplying section that supplies a yarn; a winding section that winds the yarn supplied from the yarn supplying section to form a package; a yarn thickness detecting section that detects thickness of the yarn that is being wound into the package; a yarn length detecting section that detects a length of the yarn that has been wound into the package; a yarn specific gravity storage section that stores therein information on a specific gravity of the yarn; and a weight calculating section that calculates, based on the thickness of the yarn detected by the yarn thickness detecting section, the length of the yarn detected by the yarn length detecting section, and the information on the specific gravity stored in the yarn specific gravity storage section, a yarn weight of the package formed by the winding section.
  • the yarn thickness detecting section detects the thickness of the yarn while a winding section is winding the yarn into a package.
  • the yarn length detecting section detects the length of the yarn that has been wound into the package at the current moment. Consequently, the weight of the yarn that has been wound into the package at the current moment can be accurately calculated based on the information of the thickness and the length of the yarn and also on the information of the specific gravity of the yarn. This allows for management of finished packages having a uniform weight (weight management).
  • the yarn winding apparatus further includes a winding controller that controls a yarn winding operation performed by the winding section, wherein the winding controller causes the winding section to stop winding the yarn when the yarn weight of the package calculated by the weight calculating section reaches a set weight.
  • the weight calculating section is able to accurately calculate the yarn weight of the package. Therefore, the winding of the package can be stopped when the calculated yarn weight reaches the set weight. Consequently, packages having a minimized difference with respect to the set weight can be formed, and the uniform weight can be maintained among the packages.
  • the winding controller selects and executes any one of a first winding mode and a second winding mode, the first winding mode being a mode in which the winding controller causes the winding section to stop winding the yarn when the yarn weight of the package calculated by the weight calculating section reaches a set weight, and the second winding mode being a mode in which the winding controller causes the winding section to stop winding the yarn when the length of the yarn of the package detected by the yarn length detecting section reaches a set length.
  • one of the first winding mode, in which the amount of yarn of the package is managed in accordance with the yarn weight, and the second winding mode, in which the amount of yarn of the package is managed in accordance with the yarn length, can be appropriately selected and executed.

  • the yarn monitoring section which is meant to detect a yarn defect, acquires the information on the yarn thickness.
  • the yarn weight of the package is calculated based on this information on the yarn thickness acquired by the yarn monitoring section.
  • the yarn monitoring section continuously detects the thickness of the yarn during winding of the yarn performed by the winding section, and the weight calculating section intermittently acquires information on the thickness of the yarn from the yarn thickness detecting section, and calculates the yarn weight of the package based on the acquired information on the thickness of the yarn.
  • continuous detection of the yarn thickness means that the yarn thickness is being substantially continuously detected at very close time intervals.
  • intermittent acquisition of the yarn thickness means that information is acquired from the yarn thickness detecting section in time intervals that are larger than the intervals for the detection, instead of acquiring all the information continuously detected by the yarn monitoring section.
  • the yarn monitoring section is meant to detect yarn defects included in the yarn. It is therefore preferable that the yarn thickness be continuously detected during the winding so as not to miss any yarn defect.
  • the information on the yarn thickness does not need to be acquired continuously (in real time) for the purpose of calculating the yarn weight of the package.
  • the continuously acquired information on the yarn thickness only complicates the calculation, and also requires a large capacity of the temporary memory.
  • the weight calculating section intermittently acquires the information on the yarn thickness from the yarn thickness detecting section that continuously detects the yarn thickness, and calculates the yarn weight of the package based on the acquired information.
