Description

Yarn clearing threshold setting device and yarn winding machine

Technical Field

The invention relates to a clearing threshold setting device and a yarn winding machine.

Background

For example, a control device provided in a yarn winding machine may have a function of displaying a clearing threshold (clearing limit), which is a boundary line of whether or not a yarn defect is removed, in a two-dimensional region having a coordinate axis of each of the length and the thickness of the yarn defect (see, for example, japanese patent No. 5680653).

Disclosure of Invention

Here, even if the shape of a part of the clearer stop is changed so that the number of removed yarn defects becomes a predetermined target number of removed yarn defects, the number of removed yarn defects removed by the changed clearer stop does not become the predetermined target number of removed yarn defects, and the shape of the clearer stop may be difficult to adjust.

Accordingly, an object of the present invention is to provide a clearer threshold setting device and a yarn winding machine that can display a clearer threshold for setting the number of removed yarn defects partially removed by the clearer threshold to a target number of removed yarn defects.

The yarn-clearing threshold setting device of the invention comprises: a display unit that displays a yarn cleaning threshold, which is a boundary line of whether or not a yarn defect is removed and is composed of a plurality of portions, in a two-dimensional region having the length and thickness of the yarn defect as coordinate axes, respectively; a first input unit that accepts selection of at least one of the parts; a removal number acquisition unit that acquires a target removal number of yarn defects to be removed from the selected portion; a clearing threshold processing part which generates a clearing threshold; a display control unit that causes the display unit to display the generated clearing threshold; and a storage unit for storing yarn defect data, which is data indicating a plurality of yarn defects of the length and thickness of the yarn defect. When a portion is selected via the first input unit and the removal number acquisition unit acquires the target removal number, the clearing threshold processing unit generates a temporary clearing threshold based on the yarn defect data and the target removal number such that the removal number of the yarn defects in the selected portion becomes the target removal number. The display control unit causes the display unit to display the provisional clearing threshold based on the target removal number generated by the clearing threshold processing unit.

The clearing threshold setting device can select a part of the clearing threshold. The clearing threshold setting device generates a temporary clearing threshold so that the number of the removed yarn defects removed according to the selected portion becomes the input target number of the removed yarn defects, and causes the display unit to display the generated temporary clearing threshold. Thus, according to the clearing threshold setting device, the clearing threshold for setting the number of yarn defects removed by a part of the clearing threshold to the target number of removal can be displayed. Thus, the operator can confirm the clearer that the removal number of yarn defects removed from the target portion is the target removal number by selecting the target portion and inputting the target removal number.

The display unit may be a touch panel.

The first input unit may be a current clearing threshold displayed on the display unit, and may receive a selection of a touched portion among the plurality of portions. Thereby, the operator can easily select a desired part of the clearing threshold.

The display control unit may cause the display unit to display a plurality of first keys corresponding to the plurality of portions, respectively, and the first input unit may receive a selection of a portion corresponding to a touched first key among the plurality of first keys, the plurality of first keys being displayed on the display unit. Thus, the operator can easily select a desired portion of the clearing threshold even for a portion where the clearing threshold is displayed finely.

When the display unit displays the provisional clearer threshold based on the target removal count, the display control unit may display the selected portion so that the selected portion can be recognized through the first input unit. Thus, the operator can easily grasp the selected portion of the plurality of portions constituting the clearing threshold.

The clearing threshold processing unit may generate a temporary clearing threshold based on the target removal number in association with the acquisition of the target removal number by the removal number acquiring unit via the first input unit selecting portion, and the display control unit may cause the display unit to display the temporary clearing threshold based on the target removal number in association with the generation of the temporary clearing threshold based on the target removal number. That is, when the target removal number is input, the clearing threshold setting means automatically generates and displays a tentative clearing threshold corresponding to the target removal number. Thus, the operator can immediately confirm the tentative yarn-clearing threshold corresponding to the input target removal number.

The yarn-clearing threshold setting device may further include: a second input unit that accepts selection of at least one of the plurality of portions of the current clearing threshold displayed on the display unit; a third input unit that indicates a plurality of moving directions in which the clearer is moved on the two-dimensional area and accepts selection of the moving direction; and a removal number calculation unit that calculates the number of removed yarn defects based on the clearing threshold, wherein the clearing threshold processing unit generates a temporary clearing threshold for moving the selected portion by a predetermined amount in the selected moving direction when the portion is selected via the second input unit and the moving direction is selected via the third input unit, the removal number calculation unit calculates the number of removed yarn defects removed according to the selected portion based on the temporary clearing threshold generated by the movement of the portion and the yarn defect data when the temporary clearing threshold is generated by moving the portion, and the display control unit causes the display unit to display the number of removed yarn defects calculated by the removal number calculation unit and the temporary clearing threshold generated by the movement of the portion. Thereby, it is possible to select a part of the clearing threshold and move the selected part. The third input for moving the selected section shows a plurality of directions of movement for the clearing threshold. Therefore, the operator can intuitively move the selected portion in a desired movement direction via the third input unit. The clearing threshold setting device calculates the number of removal of yarn defects according to the partial removal selected via the second input unit based on the provisional clearing threshold, and causes the display unit to display the calculated number of removal. Thus, the operator can grasp the number of yarn defect removals changed by moving the portion constituting the clearing threshold, and the clearing threshold after the movement (provisional clearing threshold).

The second input unit may be configured to receive a selection of a touched portion among the plurality of portions, the selection being based on the current clearing threshold displayed on the display unit. Thereby, the operator can easily select a desired part of the clearing threshold.

The display control unit may cause the display unit to display a plurality of second keys corresponding to the plurality of portions, respectively, and the second input unit may receive a selection of a portion corresponding to a touched second key among the plurality of second keys, the plurality of second keys being displayed on the display unit. Thus, the operator can easily select a desired portion of the clearing threshold even for a portion where the clearing threshold is displayed finely.

When the display unit displays the provisional clearer threshold generated by the movement of the portion, the display control unit may display the portion selected through the second input unit so that the portion can be recognized. Thus, the operator can easily grasp the selected portion of the plurality of portions constituting the clearing threshold.

The third input unit may be an operation unit for causing the display control unit to display the display unit. Thus, the operator can be provided with the operation unit at an appropriate timing by displaying the display unit without providing a separate operation unit.

The removal number calculation unit may calculate the number of removed yarn defects in association with the generation of the temporary clearing threshold by moving the selected portion, and the display control unit may display the temporary clearing threshold generated by the movement of the portion and the calculated number of removed yarn defects in association with the generation of the temporary clearing threshold and the calculation of the number of removed yarn defects by moving the portion. That is, when the moving direction of the portion constituting the clearing threshold is inputted, the clearing threshold setting means automatically displays the number of removals according to the portion to which the moving direction is inputted and the tentative clearing threshold after moving the selected portion. Thus, the operator can immediately confirm the number of yarn defect removals corresponding to the movement of the portion constituting the clearing threshold and the provisional clearing threshold after the selected portion has been moved.

The display control unit may cause the display unit to display the current clearing threshold together with the provisional clearing threshold. Thus, the operator can compare the current clearing threshold with the tentative clearing threshold.

The clearing threshold processing unit may set the current clearing threshold or the provisional clearing threshold as the new clearing threshold. Thus, the operator can set the current clearing threshold or the temporary clearing threshold as the new clearing threshold.

The plurality of portions constituting the yarn clearer may be set according to the type of the yarn defect. Thus, a part of the yarn clearer can be easily selected according to the type of the yarn defect. In addition, the yarn defect can be removed in a desired number of removal steps for the selected type of yarn defect.

When the target removal count for a plurality of portions including the selected portion is input, the removal count acquisition unit may acquire the target removal count assigned to the selected portion by assigning according to a predetermined method as the target removal count to be removed from the selected portion. Thus, even if the target removal count of the selected portion is not directly input, the target removal count corresponding to the selected portion can be acquired.

The yarn winding machine of the present invention comprises: a yarn supplying section that supplies a yarn; a winding section that winds the yarn to form a package; a yarn monitoring section that monitors a yarn between the yarn supplying section and the winding section and detects a yarn defect; a yarn joining section that performs a yarn joining operation of joining the yarn on the yarn supplying section side and the yarn on the winding section side when the yarn is cut to remove the yarn defect detected by the yarn monitoring section; and the yarn clearing threshold setting device.

Since the yarn winding machine has the above-described clearing threshold setting device, the above-described temporary clearing threshold can be displayed, and the yarn defect can be appropriately removed.

According to the present invention, it is possible to display the clearing threshold for setting the number of removal of yarn defects partially removed by the clearing threshold to the target number of removal.

Detailed Description

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. In the drawings, the same or corresponding portions are denoted by the same reference numerals, and redundant description is omitted.

As shown in fig. 1, a yarn winding machine 1 includes a plurality of yarn winding units 2, a plurality of unit control devices 3, and a machine body control device (yarn-clearing threshold setting device) 4. The yarn winding machine 1 is, for example, an automatic winder, an air spinning machine, a free end spinning machine, a ring spinning machine, or the like. Each yarn winding unit 2 winds a yarn to form a package. Each unit control device 3 is provided for each of the plurality of yarn winding units 2, and controls the operation of the plurality of managed yarn winding units 2. The body control device 4 communicates with each unit control device 3, and controls the operation of the yarn winding machine 1. Each unit control device 3 may be provided for each yarn winding unit 2.

As shown in fig. 2, each yarn winding unit 2 includes a yarn supplying section 21, a yarn monitoring section 22, a yarn splicing section 23, and a winding section 24. When the yarn winding machine 1 is an automatic winder, each yarn winding unit 2 may be provided with a tension applying device for applying tension to the yarn, a tension sensor for measuring the tension of the yarn, and the like. When the yarn winding machine 1 is an air spinning machine, each yarn winding unit 2 may be provided with a tension sensor for measuring the tension of the yarn, a yarn accumulating device for accumulating the yarn, a waxing device for waxing the yarn, and the like.

The yarn supplying portion 21 supplies a yarn. In the case where the yarn winding machine 1 is an automatic winder, the yarn supplying portion 21 is constituted by a bobbin supporting device or the like that supports a yarn supplying bobbin. In the case where the yarn winding machine 1 is an air spinning machine, the yarn supplying section 21 is configured by a draft device that drafts a fiber bundle, an air spinning device that twists the drafted fiber bundle with a swirling air flow to generate a yarn, and the like.

The yarn monitoring section 22 monitors the yarn between the yarn supplying section 21 and the winding section 24 to detect a yarn defect. The yarn monitoring unit 22 includes a detection device 22a and a control device 22 b. The detection device 22a is an optical sensor that irradiates light to the yarn and detects a temporal change in the thickness (diameter) of the yarn from a change in the amount of received light, a capacitance sensor that passes the yarn through an electric field and detects a temporal change in the thickness (amount) of the yarn from a change in capacitance, or the like. The detection device 22a outputs waveform data indicating temporal changes in the yarn thickness to the control device 22 b. The controller 22b calculates yarn defect data, which is data indicating a plurality of yarn defects including the length and thickness of the yarn defect, based on the waveform data, and outputs the yarn defect data to the unit controller 3. When the unit control device 3 determines that the yarn defect should be removed based on the yarn defect data, the yarn is cut by, for example, a cutter provided in the yarn winding unit 2. When the yarn winding machine 1 is an air spinning machine, the yarn may be cut by interrupting the generation of the yarn by the air spinning device. The yarn monitoring unit 22 can also detect foreign matter, yarn breakage, and the like contained in the yarn.

The yarn joining section 23 performs a yarn joining operation of joining the yarn on the yarn supplying section 21 side and the yarn on the winding section 24 side when the yarn is cut to remove the yarn defect detected by the yarn monitoring section 22 or the yarn breakage is detected by the yarn monitoring section 22. The yarn joining section 23 is constituted by a first yarn catching and guiding device, a second yarn catching and guiding device, a yarn joining device, and the like. The first yarn catching and guiding device catches the yarn on the yarn supplying portion 21 side by a suction action and guides the yarn to the yarn splicing device. The second yarn catching and guiding device catches the yarn on the winding portion 24 side by suction and guides the yarn to the yarn splicing device. The yarn splicing device is a splicer using compressed air, a splicer (pick) using a reference yarn, a knotter mechanically connecting yarns, or the like, and connects the guided yarns to each other. In the case where the yarn winding machine 1 is, for example, a spinning machine, the yarn joining section 23 may be configured as a yarn joining cart that can travel relative to the plurality of yarn winding units 2.

The winding section 24 winds the yarn around the bobbin to form a package. The winding section 24 is constituted by a cradle arm, a winding tube, a traverse device, and the like. The cradle arm rotatably supports the package. The winding drum rotates the package by contacting a surface of the package supported by the cradle arm. The traverse device traverses the yarn at a predetermined width with respect to the rotating package. Further, there are a case where the motor directly rotates the package, a case where the winding tube has a traverse groove, and the like.

As shown in fig. 3, the body control device 4 includes a touch panel (display unit) 41, a processing unit 42, and a storage unit 43. The touch panel 41 displays various information to the operator or receives input of various information by the operator. The processing unit 42 acquires yarn defect data output from the yarn monitoring unit 22 of each yarn winding unit 2 from each unit control device 3. The processing unit 42 associates the acquired yarn defect data with information indicating whether the yarn defect has been removed or the yarn defect remains, and stores the information in the storage unit 43 for each yarn winding unit 2. The Processing Unit 42 and the storage Unit 43 are physically configured by a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like.

The processing unit 42 functionally includes a removal number acquisition unit 42a, a clearing threshold processing unit 42b, a removal number calculation unit 42c, and a display control unit 42 d.

The display control unit 42d generates a two-dimensional area and causes the touch panel 41 to display the two-dimensional area together with the clearing threshold generated by the clearing threshold processing unit 42 b. Fig. 4 is a diagram showing an example of a screen of the touch panel 41. As shown in fig. 4, the two-dimensional region 51 is a coordinate system having the length and thickness of the yarn defect as coordinate axes. Here, the horizontal axis represents the length of the yarn defect, and the vertical axis represents the thickness of the yarn defect (the ratio of the thickness to the reference thickness of the yarn). The clearing threshold 52 is a boundary line for removing or not removing a yarn defect and is composed of a plurality of portions 52 a. Here, the yarn clearer 52 is set for each type (channel) of yarn defect type, such as neps N1, N2, short slubs S1, S2, long slubs L, long thin sections T1, and T2. That is, the plurality of portions 52a correspond to the kinds of yarn defects (neps N1, N2, short nubs S1, S2, long nubs L, long nubs T1, T2, and the like), respectively. That is, the yarn clearer 52 is configured to be a boundary line which is divided (divided) into a plurality of portions 52a in advance in accordance with the type of the yarn defect. Thus, a part of the yarn clearer 52 can be easily selected and changed according to the type of the yarn defect.

The processing unit 42 causes each unit control device 3 to control the operation of each yarn winding unit 2 so that a yarn defect having a value on the yarn reference thickness side (the traverse side where the thickness of the yarn defect is 0%) with respect to the clearer 52 is a target for remaining and a yarn defect having a value on the opposite side of the yarn reference thickness side (the traverse side where the thickness of the yarn defect is 0%) with respect to the clearer 52 is a target for removal.

The display control unit 42d determines the position of the yarn defect in the two-dimensional area 51 based on the yarn defect data stored in the storage unit 43, and displays the yarn defect by dot on the touch panel 41. Here, the display control unit 42d displays the yarn defect remaining on the yarn in the two-dimensional region 51 as a hollow dot, and displays the yarn defect removed from the yarn in the two-dimensional region 51 as a blackened square dot. In addition, only a predetermined number of spots indicating yarn defects from the present to the past are displayed on the touch panel 41.

The display control unit 42d causes the touch panel 41 to display the current setting value field 53 and the analog setting value field 54. The setting information of the current clearing threshold 52 (the currently set clearing threshold 52) is shown in the current setting value column 53. Specifically, the current set value column 53 shows the current values of the length and thickness of the yarn defect for each type, which determine the current yarn clearer 52. The setting information for the tentative clearing threshold 52 is shown in the analog setting field 54. Specifically, the simulation set value column 54 shows the simulation values of the length and thickness of the yarn defect for each type, which determine the provisional clearer threshold 52. Each of the portions 52a constituting the current yarn cleaning threshold 52 is set so as to include the current values of the length and thickness of the yarn defect. For example, when at least one portion 52a of the current yarn clearer 52 is changed (described later in detail), the analog values of the length and thickness of the yarn defect are changed so as to correspond to the changed portion 52 a.

In the current setting value column 53 and the analog setting value column 54, ALL at the left end indicates that ALL types are included. In the current setting value column 53 and the analog setting value column 54, a portion indicating each type (ALL, N1, N2, S1, S2, L, T1, and T2) including ALL on the left side is configured as a key (second key) 55. In this way, the display control unit 42d causes the touch panel 41 to display the keys 55 corresponding to the plurality of sections 52a of the clearing threshold 52.

The display control unit 42d causes the touch panel 41 to display the current result field 56 and the simulation result field 57. In the current result column 56, the number of removed yarn defects (n) and the number of removed yarn defects (/100km) in the case where the number is converted per unit length (here, 100km) are shown for each type as the result of the yarn processing in the current yarn clearing threshold 52. The number of yarn defect removals (n) in the current result column 56 is the actual number of removed yarn defects, and corresponds to the number of yarn defects having a value in a region opposite to the yarn reference thickness side (the crossmember side where the thickness of the yarn defect is 0%) with respect to the current clearer gate 52. In addition, the current result column 56 may display the number of yarn defects removed when the number of yarn defects removed (n) is converted per unit time (for example, 1 hour).

The yarn processing results in the tentative clearing threshold 52 are shown in the simulation results column 57. In the simulation result column 57, as the yarn processing result in the provisional clearer gate 52, the number of removed yarn defects (n) and the number of removed yarn defects (/100km) in the case where the number is converted per unit length (here, 100km) are displayed for each type. The number of yarn defect removals (n) in the simulation result column 57 is a predicted number based on the actually measured number of removed yarn defects, and corresponds to the number of yarn defects having a value in a region opposite to the yarn reference thickness side (the traverse axis side where the thickness of the yarn defect is 0%) with respect to the provisional clearer 52. The simulation result column 57 may display the number of yarn defects removed in the case where the number of yarn defects removed (n) is converted per unit time (for example, 1 hour).

In the current result field 56 and the simulation result field 57, neps N at the left end correspond to neps N1 and N2. The short bold S corresponds to the short bold S1, S2. The long nubs L correspond to the long nubs L. Long detail T corresponds to long details T1, T2. Sum corresponds to the total type of neps N1, N2, short nubs S1, S2, long nubs L, long details T1, T2. YF corresponds to the total type of neps N1, N2, short knots S1, S2, long knots L, long knots T1, T2, and types other than these (for example, F type indicating that foreign matter is mixed in (color is mixed in), C type indicating that the number of counts (yarn thickness) is different, and the like). The current result field 56 and the simulation result field 57 each indicate that each type of portion including YF and Sum is a button (first button) 58. In this way, the display control unit 42d causes the touch panel 41 to display the keys 58 corresponding to the plurality of sections 52a of the clearing threshold 52.

The clearing threshold processing section 42b generates a clearing threshold 52. Specifically, for example, when the clearing threshold 52 is not generated at the beginning of winding of the yarn, the clearing threshold processing unit 42b generates the clearing threshold 52 based on an initial value set in advance by an operator. For example, the yarn defect data is not accumulated in the storage section 43 at the beginning of winding the yarn. Therefore, the clearing threshold processing unit 42b generates the clearing threshold 52 based on an initial value set by an operator based on past experience or the like. Further, when a predetermined amount of yarn defect data is accumulated after the start of winding of the yarn, the clearer threshold processing unit 42b may automatically generate the clearer threshold 52 based on the distribution of the accumulated yarn defect data in the two-dimensional area.

The clearing threshold processing unit 42b generates the clearing threshold 52 based on the clearing simulation instruction of the operator. Here, the clearing simulation includes two simulations. The first clearing simulation is a simulation of predicting a clearing threshold 52 for achieving a target removal number based on the target removal number of the yarn defect. The second clearing simulation is a simulation in which at least one of the sections 52a constituting the clearing threshold 52 is moved and the number of removed yarn defects is predicted based on the provisional clearing threshold 52 after the section 52a is moved. The first and second yarn cleaning simulations will be described later in detail.

The removal number acquiring unit 42a acquires a target removal number for removing a yarn defect when the first clearing simulation is executed. The operator can input the target removal count using an input key provided in the device control apparatus 4, an input key displayed on the touch panel 41, or the like. The removal count acquisition unit 42a acquires a target removal count input via an input key or the like provided in the machine body control device 4. The target removal number may be input to the body control device 4 by an input mechanism (predetermined input unit) other than the input keys.

The removal number calculating section 42c calculates (predicts) the removal number of the removed yarn defect based on the clearing threshold when the second clearing simulation is executed.

The first and second yarn clearing simulations will be described below by way of example.

(first yarn cleaning simulation)

First, a first clearing simulation in which the clearing threshold 52 for achieving the target removal number is predicted (generated) based on the target removal number of the yarn defect will be described. Here, the current clearing threshold 52 is set. The current clearing threshold 52 is the clearing threshold 52 actually set for removing the yarn defect. The processing unit 42 causes each unit control device 3 to control the operation of each yarn winding unit 2 so as to remove the yarn defect based on the set current clearer threshold 52. The operator performs the first clearing simulation, for example, when attempting to confirm the clearing threshold 52 in which the number of removed yarn defects is changed.

The operator selects the portion 52a (type) whose number of yarn defects to be removed is to be changed. Specifically, for example, as shown in fig. 5, the operator selects the portion 52a by touching (pressing, physically contacting, etc.) the key 58 corresponding to the short bold S among the plurality of keys 58. In this case, the operator can select the keys 58 corresponding to the types other than the short bold S among the plurality of keys 58 or collectively select the plurality of keys 58.

In this way, the plurality of keys 58 (the plurality of keys 58 displayed on the touch panel 41 separately from the counting gate 52) corresponding to the plurality of sections 52a constituting the counting gate 52 function as a first input unit that receives selection of the section 52a corresponding to at least one of the keys 58 touched. The display control unit 42d may cause the touch panel 41 to display the portion 52a selected via the key 58 so that the portion 52a can be recognized, or may cause the touch panel 41 to display the key 58 corresponding to the portion 52a so that the key 58 can be recognized.

The operator selects the section 52a (type) by touching (pressing, physical contact, etc.) the section 52a corresponding to the short slubs S (short slubs S1 and S2) in the current clearing threshold 52 displayed on the touch panel 41. In this case, the operator can select the section 52a corresponding to the type other than the short slub S in the current clearing threshold 52, and can select one section 52a from among them, or collectively select a plurality of sections 52 a.

In this way, the clearer gate 52 displayed on the touch panel 41 functions as a first input unit that accepts selection of at least one touched portion 52 a. The display control unit 42d may cause the touch panel 41 to display the part 52a selected via the clearer 52 so that the part 52a can be recognized, or may cause the touch panel 41 to display the key 58 corresponding to the part 52a so that the key 58 can be recognized.

Next, the operator inputs the target removal number of yarn defects to be removed in the selected portion 52a using an input key or the like provided in the machine body control device 4. The removal number acquiring unit 42a acquires the input target removal number. In the example of fig. 5, 0.7 is inputted as a target removal number of the number of yarn defects removed per unit length (/100km) in the short slub S. Thus, the display control unit 42d displays 0.7 in the simulation result column 57 as a numerical value of the number of yarn defects removed per unit length (/100km) in the short slub S. The simulation values corresponding to YF and Sum in the simulation result column 57 and the number (n) of removed yarn defects in the short slub S are also changed in conjunction with the number (/100km) of removed yarn defects per unit length in the short slub S. The values other than these in the simulation result column 57 are the same as those in the current result column 56.

When the selection of the portion 52a to be subjected to the change of the removal count is accepted and the removal count acquiring unit 42a acquires the target removal count, the clearing threshold processing unit 42b generates the temporary clearing threshold 52 based on the yarn defect data stored in the storage unit 43 and the acquired target removal count so that the removal count of the yarn defects removed by the selected portion 52a becomes the target removal count. Here, the temporary clearing threshold 52 is the clearing threshold 52 temporarily created for confirmation or the like by the operator. Therefore, the actual yarn processing is not carried out at this stage using the temporary clearing threshold 52.

In the case of performing the yarn cleaning simulation using the yarn defect data stored in the storage unit 43, it is preferable to use the yarn defect data based on the yarn processing result (winding length) of 100km or more from the present to the past from the viewpoint of accuracy. However, the yarn defect data based on the yarn processing result of 100km or more in the past is not limited to the above, and the yarn defect data based on the yarn processing result of less than 100km may be used to perform the yarn cleaning simulation. For example, it may be that "100 km" is set as a standard, and the setting can be changed in such a manner as to increase to "200 km" or shorten to "80 km". In this case, for example, the display control unit 42d may display a warning display 59 indicating that the yarn defect data based on the yarn processing result of less than 100km is used for the yarn cleaning simulation.

Further, for example, when the operator selects the key 58 of YF and inputs the target removal count, the clearing threshold processing unit 42b assigns the target removal count to each type of neps N, short slubs S, long slubs L, and long slubs T included in YF, and generates the temporary clearing threshold 52 so that the removal count of the yarn defect removed by the portion 52a corresponding to each type becomes the target removal count assigned to each type. The clearer threshold processing unit 42b can adopt various allocation methods such as performing allocation by weighting based on the measured value of the number of removal of the past yarn defects when allocating the target removal number to each type. When the operator selects the key 58 on YF, the display control unit 42d may assign the target removal count to another type (for example, type C) in addition to the neps N, the short knots S, the long knots L, and the long knots T. Similarly, when the operator selects the button 58 of Sum and inputs the target removal count, the clearing threshold processing unit 42b assigns the target removal count to each type of neps N, short slubs S, long slubs L, and long slubs T included in Sum, and generates the provisional clearing threshold 52. When the YF or Sum button 58 is selected and the number of target removals is assigned by the clearing threshold processing unit 42b, the display control unit 42d displays the number of target removals assigned to each type in the simulation result field 57. When the operator inputs the target removal count for a plurality of portions including the selected portion 52a (for example, when the target removal count for the entire clearing threshold 52 is input), the removal count acquisition unit 42a acquires the target removal count assigned to the selected portion 52a by a predetermined method as the target removal count to be removed in the selected portion 52 a.

When the provisional clearing threshold 52 based on the target removal number is generated by the clearing threshold processing unit 42b, the display control unit 42d causes the touch panel 41 to display the current clearing threshold 52 together with the provisional clearing threshold 52 based on the target removal number. At this time, when the touch panel 41 displays the provisional clearer gate 52 based on the target removal count, the display controller 42d displays the portion 52a selected by the operator so as to be recognizable. In the example of fig. 5, the current clearing threshold 52 is shown in solid lines and the tentative clearing threshold 52 based on the target removal number is shown in solid and dashed lines. The provisional clearing threshold 52 based on the target removal number is different in shape (dotted line portion) from the current clearing threshold 52 in the portion 52a corresponding to the short thick S (S1, S2) selected by the operator.

The display control unit 42d causes the touch panel 41 to display the analog value for determining the provisional clearer threshold 52 based on the target removal count in the analog set value field 54. When the analog set value is displayed in the analog set value column 54, the display control unit 42d may display the analog value of the type corresponding to the part 52a selected by the operator so that the analog value can be recognized. That is, the analog value of the type corresponding to the section 52 selected by the operator is an analog value of a portion different from the current setting value displayed in the current setting value column 53. In the example of fig. 5, the simulation values regarding the thicknesses of the short slubs S1, S2 are changed based on the first clearing simulation result.

The clearing threshold processing unit 42b generates a provisional clearing threshold 52 based on the target removal number in conjunction with the case where the operator selects the portion 52a for which the removal number of yarn defects is to be changed and the removal number acquiring unit 42a acquires the target removal number. That is, the clearing threshold processing unit 42b automatically generates the temporary clearing threshold 52 based on the target removal count without waiting for another instruction from the operator for generating the temporary clearing threshold 52, with the trigger condition that the operator selects the portion 52a for which the removal count of the yarn defect is to be changed and the removal count acquiring unit 42a acquires the target removal count.

In addition, the display control unit 42d causes the touch panel 41 to display the temporary clearing threshold 52 based on the target removal number and the analog value for determining the temporary clearing threshold 52 in conjunction with the generation of the temporary clearing threshold based on the target removal number by the clearing threshold processing unit 42 b. That is, the display control unit 42d automatically displays the temporary clearing threshold 52 based on the target removal count and the simulation value for determining the temporary clearing threshold 52, without waiting for another instruction from the operator for displaying the temporary clearing threshold 52, with the temporary clearing threshold based on the target removal count generated by the clearing threshold processing unit 42b as a trigger condition.

The clearing threshold processing section 42b sets the current clearing threshold 52 or the provisional clearing threshold 52 displayed on the touch panel 41 as a new clearing threshold. The setting of the clearing threshold 52 is carried out by the operator who has confirmed the result of the first clearing simulation touching a button for selecting the current clearing threshold 52 or the provisional clearing threshold 52.

For example, the display control unit 42d causes the touch panel 41 to display the ok button 71 and the cancel button 72. When the operator touches the determination button 71, the clearing threshold processing unit 42b sets the provisional clearing threshold 52 as the new clearing threshold 52. After the tentative clearing threshold 52 is set to the new clearing threshold 52, the tentative clearing threshold 52 becomes the current clearing threshold 52. Thus, the determination button 71 becomes a button for reflecting the provisional clearer threshold 52 to the actual removal of the yarn defect in the first clearer simulation.

On the other hand, when the operator touches the cancel button 72, the clearing threshold processing unit 42b cancels the provisional clearing threshold 52 and sets the current clearing threshold 52 as the new clearing threshold 52. That is, when the cancel key 72 is touched, the clearing threshold processing unit 42b maintains the current clearing threshold 52 as the clearing threshold 52. Thus, the cancel button 72 becomes a button for invalidating the simulated tentative clearing threshold 52 and maintaining the current clearing threshold 52 in the first clearing simulation.

(second yarn cleaning simulation)

Next, a second clearing simulation will be described in which at least one of the sections 52a constituting the clearing threshold 52 is moved, and the number of removed yarn defects is predicted based on the temporary clearing threshold 52 after the section 52a is moved. Here, the current clearing threshold 52 is set. The operator performs the second clearing simulation, for example, when attempting to confirm the number of yarn defects removed after moving (changing) the portion 52a of the current clearing threshold 52.

The operator selects a section 52a (type) as a moving object from among a plurality of sections 52a constituting the current clearing threshold 52 displayed on the touch panel 41. Specifically, for example, as shown in fig. 6, the operator selects the portion 52a by touching (pressing, physically contacting, etc.) the key 55 corresponding to the short bold S1 among the plurality of keys 55. In this case, the operator can select the keys 55 corresponding to the types other than the short bold S1 among the plurality of keys 55, or collectively select the plurality of keys 55. For example, the operator can select ALL the types by touching the key 55 corresponding to ALL.

In this way, the plurality of keys 55 (the plurality of keys 55 displayed on the touch panel 41 separately from the clearing threshold 52) corresponding to the plurality of sections 52a constituting the current clearing threshold 52 function as the second input unit that receives the selection of the section 52a corresponding to at least one of the keys 55 touched. The display control unit 42d may cause the touch panel 41 to display the portion 52a selected via the key 55 so that the portion 52a can be recognized, or may cause the touch panel 41 to display the key 55 corresponding to the portion 52a so that the key 55 can be recognized.

The operator selects the section 52a (type) by touching (pressing, physical contact, etc.) the section 52a corresponding to the short bold S1 in the current clearing threshold 52 displayed on the touch panel 41. At this time, the operator can select the section 52a corresponding to the type other than the short bold S1 in the current clearing threshold 52 or collectively select a plurality of sections 52 a.

In this way, the clearer 52 displayed on the touch panel 41 functions as a second input unit that accepts selection of at least one touched portion 52 a. The display control unit 42d may cause the touch panel 41 to display the part 52a selected via the clearer 52 so that the part 52a can be recognized, or may cause the touch panel 41 to display the key 55 corresponding to the part 52a so that the key 55 can be recognized.

When the operator selects the portion 52a to be moved, the display control unit 42d causes the touch panel 41 to display the operation unit 60. The operation unit 60 functions as a third input unit that indicates a plurality of moving directions in moving the clearer 52 over the two-dimensional area and accepts selection of the moving directions. Specifically, the operation unit 60 includes a movement direction instruction key 61, a movement amount switching key 62, and a display cancel key 63. The movement direction instruction button 61 indicates a plurality of movement directions for each predetermined angle and accepts selection of a movement direction. Here, the movement direction instruction keys 61 are arranged one at every 45 degrees around the movement amount switching key 62, and indicate the movement directions of up, right down, left up, and left down in the order of clockwise.

When a part to be moved is selected via the clearer gate 52 or the key 55 and the moving direction is selected via the operation unit 60, the clearer gate processing unit 42b generates a temporary clearer gate 52 in which the selected part is moved by a predetermined amount in the selected moving direction. The display control unit 42d causes the touch panel 41 to display the provisional clearing threshold 52 generated by the movement of the section 52a in the clearing threshold processing unit 42 b.

For example, as shown in fig. 6, when the operator touches the movement direction instruction button 61 indicating the downward movement direction, the section 52a corresponding to the selected short bold S1 is displayed to move downward by a predetermined amount and to display a provisional clearer threshold 52. When the provisional clearing threshold 52 based on the movement of the section 52a is generated by the clearing threshold processing unit 42b, the display control unit 42d causes the touch panel 41 to display the current clearing threshold 52 together with the provisional clearing threshold 52 generated based on the movement of the section 52 a. At this time, when the touch panel 41 displays the temporary clearing threshold 52 generated by the movement of the section 52a, the display control unit 42d displays the section 52a selected by the operator so that the section can be recognized. In the example of fig. 6, the current clearing threshold 52 is shown in solid lines and the temporary clearing threshold 52 generated by the movement of the section 52a is shown in solid and dashed lines. The provisional clearing threshold 52 generated by the movement of the portion 52a is different in shape (in dashed lines) from the portion 52a corresponding to the short bold S1 selected by the operator with respect to the current clearing threshold 52.

The display control unit 42d causes the touch panel 41 to display a simulated value in the simulated setting value field 54, and the simulated value determines the provisional clearer threshold 52 generated by the movement of the section 52 a. When the analog set value is displayed in the analog set value column 54, the display control unit 42d may display the analog value of the type corresponding to the part 52a selected by the operator so that the analog value can be recognized. That is, the analog value of the type corresponding to the part 52a selected by the operator is an analog value of a portion different from the current setting value displayed in the current setting value column 53. In the example of fig. 6, the simulated value regarding the thickness of the short bar S1 corresponding to the part 52a selected by the operator is changed based on the moving direction selected by the operator.

In the operation unit 60, the movement amount switching key 62 receives switching of the amount (predetermined amount) by which the selected portion 52a is moved by one touch of the movement direction instruction key 61. The clearer threshold processing unit 42b switches the movement amount so as to be × 1 (movement amount 1 times the reference value), × 10 (movement amount 10 times the reference value), and × 100 (movement amount 100 times the reference value), for example, each time the movement amount switching key 62 is touched. The reference value of the movement amount can be set for each type.

The display cancel button 63 receives cancellation of display of the operation unit 60 by the touch panel 41. That is, the display control unit 42d causes the touch panel 41 to display the operation unit 60 when the selection of at least one portion 52a is accepted by the clearer 52 or the button 55, but cancels the display of the operation unit 60 and cancels the selection of the portion 52a when the display cancel button 63 is touched.

In the above description, the case where the selected portion 52a is moved using the operation unit 60 has been described, but the operation unit 60 is not limited to this. For example, after selecting the part 52a to be moved, the clearing threshold processing unit 42b may generate the temporary clearing threshold 52 so as to include the input analog value when the analog value in the analog set value field 54 is input by the operator. That is, the clearing threshold processing unit 42b may move the selected section 52a based on the input analog value. The operator can input the analog value for determining the provisional clearer threshold 52 using an input key provided in the body control device 4, an input key displayed on the touch panel 41, or the like.

When the section 52a is moved to generate the temporary clearing threshold 52, the removal number calculation unit 42c calculates the number of removal of the yarn defect by the selected section 52a based on the temporary clearing threshold 52 generated by the movement of the section 52a and the yarn defect data stored in the current setting value column 53. When the number of yarn defects removed by the selected portion 52a is calculated, the display controller 42d causes the touch panel 41 to display the calculated number of yarn defects removed. In the example of fig. 6, the removal number calculated by the removal number calculation unit 42c is displayed in the simulation result field 57 as a simulation value of the short bar S including the short bar S1 selected as the movement target by the operator. The simulation values corresponding to YF and Sum in the simulation result column 57 are also changed in conjunction with the simulation values corresponding to the short bold S. The values other than these in the simulation result column 57 are the same as those in the current result column 56.

The clearing threshold processing unit 42b generates a provisional clearing threshold 52 by moving the selected portion 52a in conjunction with the selection of the portion 52a to be moved by the operator and the selection of the moving direction via the operation unit 60. That is, the clearing threshold processing unit 42b generates the temporary clearing threshold 52 by moving the part 52a without waiting for another instruction from the operator for generating the temporary clearing threshold 52, with the part 52a selected by the operator as the moving target part 52a and the moving direction selected via the operation unit 60 as the trigger condition. Further, when the analog value for determining the temporary clearing threshold 52 is input to the analog set value field 54 instead of selecting the moving direction in the operation unit 60, the clearing threshold processing unit 42b generates the temporary clearing threshold 52 in conjunction with the input of the analog value.

The removal number calculation unit 42c calculates the number of removed yarn defects in conjunction with the generation of the temporary clearer gate 52 by moving the section 52 a. That is, the removal number calculating section 42c automatically calculates the removal number of the yarn defect without waiting for other instructions of the operator for calculating the removal number of the yarn defect, using the temporary clearer threshold 52 generated by moving the section 52a as a trigger.

The display control unit 42d causes the touch panel 41 to display the temporary clearing threshold 52 generated by the movement of the section 52a and the calculated number of removal of the yarn defect in conjunction with the generation of the temporary clearing threshold 52 by the movement of the section 52a and the calculation of the number of removal of the yarn defect. That is, the display control unit 42d automatically displays the temporary clearing threshold 52 and the calculated number of removed yarn defects on the touch panel 41 without waiting for another instruction from the operator, using the trigger condition of the generation of the temporary clearing threshold 52 and the calculation of the number of removed yarn defects by moving the section 52 a. Thus, the operator can move the portion 52a by operating the operation unit 60 while viewing the touch panel 41, and can check the number of removed yarn defects that change according to the movement of the portion 52 a.

The clearing threshold processing section 42b sets the current clearing threshold 52 or the provisional clearing threshold 52 displayed on the touch panel 41 as a new clearing threshold. The setting of the clearing threshold 52 is carried out by the operator who has confirmed the result of the second clearing simulation touching a button for selecting the current clearing threshold 52 or the provisional clearing threshold 52.

Further, the clearing threshold processing unit 42b can set the clearing threshold 52 based on the result of the touch of the ok button 71 or the cancel button 72 by the operator, as in the case of performing the first clearing simulation. Thus, the determination button 71 becomes a button for reflecting the provisional clearer threshold 52 to the actual removal of the yarn defect in the second clearer simulation. In addition, the cancel button 72 becomes a button for invalidating the tentative clearing threshold 52 and maintaining the current clearing threshold 52 in the second clearing simulation.

The processing unit 42 may determine which of the first and second clearing simulations is to be executed based on an input result of a key for selecting the clearing simulation to be executed. Alternatively, when the part 52a constituting the clearer gate 52 is selected, the processing unit 42 may execute the first clearer simulation when the key 58 is touched and execute the second clearer simulation when the key 55 is touched.

As described above, in the machine body control device 4, at least one section 52a of the plurality of sections 52a constituting the clearing threshold 52 can be selected. The body control device 4 generates a temporary clearing threshold 52 so that the number of yarn defects removed from the selected portion 52a becomes the input target number of removal, and causes the touch panel 41 to display the generated temporary clearing threshold 52. Thus, according to the body control device 4, the clearer 52 can be displayed so that the number of yarn defects removed by at least one section 52a of the plurality of sections 52a constituting the clearer 52 becomes the target number of removal. Thus, the operator can confirm the clearer 52 having the target removal count from the number of yarn defects removed by the target portion 52a by selecting the target portion 52a and inputting the target removal count.

In the machine body control device 4, the selection of the touched portion 52a among the plurality of portions 52a is accepted by the current clearing threshold 52 displayed on the touch panel 41. Thereby, the operator can easily select the desired portion 52a of the clearing threshold 52.

In the device control apparatus 4, the plurality of keys 58 displayed on the touch panel 41 receive selection of the portion 52a corresponding to the touched key 58 among the plurality of keys 58. Similarly, in the device control apparatus 4, the plurality of keys 55 displayed on the touch panel 41 receive selection of the portion 52a corresponding to the touched key 55 among the plurality of keys 55. This allows the operator to easily select a desired portion 52a of the clearing threshold even for a portion where the clearing threshold 52 is displayed finely.

In the machine body control device 4, when the touch panel 41 is caused to display the provisional clearer gate 52 based on the target removal count, the part 52a selected by the operator may be displayed so as to be distinguishable (recognizable) from the other parts 52 a. Similarly, in the machine body control device 4, when the touch panel 41 is caused to display the provisional clearer gate 52 generated by the movement of the section, the section 52a selected by the operator may be displayed so as to be distinguishable from the other sections 52 a. Thus, the operator can easily grasp the selected section 52a among the plurality of sections 52a constituting the clearing threshold 52.

The body control device 4 generates a provisional clearer threshold 52 based on the target removal count in conjunction with the selection section 52a acquiring the target removal count, and causes the touch panel 41 to display the provisional clearer threshold 52 in conjunction with the generation of the provisional clearer threshold 52 based on the target removal count. Thus, the operator can immediately confirm the tentative clearing threshold 52 corresponding to the input target removal number.

The body control device 4 is capable of selecting at least one section 52a of the plurality of sections 52a constituting the clearing threshold 52 and moving the selected section 52 a. The operating part 60 for moving the selected portion 52a shows a plurality of directions of movement for the clearing threshold 52. Therefore, the operator can intuitively move the selected portion 52a in a desired moving direction via the operation unit 60. Further, the body control device 4 calculates the number of yarn defects removed from the portion 52a selected by the operator based on the provisional clearer threshold 52, and causes the touch panel 41 to display the calculated number of removal. Thus, the operator can grasp the number of yarn defect removals changed by moving the portion 52a constituting the clearing threshold 52, and the clearing threshold 52 after the movement (the provisional clearing threshold 52).

The operation unit 60 is displayed on the touch panel 41. Thus, the operator can be provided with the operation unit 60 at an appropriate timing by displaying the touch panel 41 without separately providing the operation unit 60.

The body control device 4 moves the selected portion to generate a provisional clearer threshold in conjunction with the selection of the moving direction by the selection portion 52a via the operation unit 60. Further, the machine body control device 4 calculates the number of yarn defects to be removed in conjunction with the case where the section 52a is moved to generate the provisional clearer threshold 52. Further, the body control device 4 causes the touch panel 41 to display the temporary clearing threshold and the calculated number of removal of the yarn defect in conjunction with the generation of the temporary clearing threshold 52 and the calculation of the number of removal of the yarn defect by moving the section 52 a. That is, when the moving direction of the section 52a constituting the clearing threshold 52 is inputted, the body control device 4 automatically displays the removal number removed according to the section 52a to which the moving direction is inputted and the provisional clearing threshold after moving the selected section 52 a. Thus, the operator can immediately confirm the number of yarn defect removals corresponding to the movement of the section 52a constituting the clearing threshold 52 and the provisional clearing threshold 52 after the selected section 52a has been moved.

In the body control device 4, the touch panel 41 is caused to display the current clearing threshold 52 together with the provisional clearing threshold 52. The operator can thus compare the current clearing threshold 52 with the provisional clearing threshold 52.

In the machine body control device 4, the current clearing threshold 52 or the temporary clearing threshold 52 may be set as the new clearing threshold 52. Thus, the operator can set the current clearing threshold 52 or the tentative clearing threshold 52 as the new clearing threshold 52.

The yarn winding machine 1 includes: a yarn supplying section 21, the yarn supplying section 21 supplying a yarn; a winding section 24 for winding the yarn to form a package; a yarn monitoring section 22 for monitoring the yarn between the yarn supplying section 21 and the winding section 24 and detecting a yarn defect in the yarn; a yarn joining section 23 that performs a yarn joining operation of joining the yarn on the yarn supplying section 21 side and the yarn on the yarn winding section 24 side when the yarn is cut to remove the yarn defect detected by the yarn monitoring section 22; and a body control device 4. Since the yarn winding machine 1 has the machine body control device 4, the above-described provisional clearer threshold 52 can be displayed, and the yarn defect can be removed appropriately.

The embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments. For example, when the first clearing simulation is performed, the current clearing threshold 52 need not be preset. The provisional clearer threshold 52 may be generated based on the yarn defect data stored in the storage unit 43 and the input target removal count.

In the first and second clearing simulations, when the section 52a to be simulated is selected, for example, the section 52a not to be simulated may be selected by touching the clearing threshold 52 or the like, and the section 52a not touched or the like may be specified as the simulation object.

In the above embodiment, the clearer 52 and the plurality of keys 58 displayed on the touch panel 41 function as the first input unit that receives selection of at least one portion 52a of the plurality of portions 52a constituting the clearer 52, but a first input unit constituted by a mechanical key or the like may be provided in addition to the touch panel 41. Similarly, the clearing threshold 52 and the plurality of keys 55 displayed on the touch panel 41 function as a second input unit that receives selection of at least one portion 52a of the plurality of portions 52a constituting the clearing threshold 52, but a second input unit constituted by a mechanical key or the like may be provided in addition to the touch panel 41.

In the above embodiment, the operation unit 60 displayed on the touch panel 41 functions as a third input unit that indicates a plurality of movement directions for the clearer 52 and receives selection of the movement directions, but a third input unit including a mechanical button, a handle, and the like may be provided in addition to the touch panel 41.

In the above embodiment, the plurality of portions 52a constituting the clearer 52 correspond to a plurality of types (types of yarn defects), respectively, but the plurality of portions 52a may be constituted by units other than types.

In the above embodiment, the display controller 42d displays the yarn defect remaining on the yarn by a hollow circular dot and displays the yarn defect removed from the yarn by a black square dot. However, the display form of the yarn defect is not limited to the hollow circular dots and the black square dots. These yarn defects may also be displayed in other display forms. For example, the display controller 42d may display the yarn defect remaining on the yarn by a green dot and display the yarn defect removed from the yarn by a red dot.

In the above embodiment, the body control device 4 of the yarn winding machine 1 functions as the clearing threshold setting device, but for example, a management device or the like separate from the yarn winding machine 1 may function as the clearing threshold setting device. Further, a yarn-clearing threshold setting device dedicated to the yarn monitoring unit 22 may be provided at the machine end of the yarn winding machine 1 in parallel with the machine control device 4. In the case where a different clearing threshold setting device from the machine body control device 4 is provided, a display portion may be provided on each of the machine body control device 4 and the clearing threshold setting device, but the machine body control device 4 and the clearing threshold setting device may share the display portion (touch panel 41). The control device 22b of the yarn monitoring section 22 may transmit and receive data directly with the clearing threshold setting device, or may transmit and receive data with the clearing threshold setting device via the unit control device 3. When the control device 22b of the yarn monitoring unit 22 and the yarn clearer setting device directly transmit and receive data, the control device 22b of the yarn monitoring unit 22 is preferably configured to be able to directly transmit and receive data also with the unit control device 3 that governs the yarn winding unit 2 on which the yarn monitoring unit 22 is mounted.

The processing unit 42 may acquire the yarn defect data from the control device 22b of the yarn monitoring unit 22 and also waveform data output from the detection device 22a of the yarn monitoring unit 22. Alternatively, the processing unit 42 may acquire only the waveform data output from the detection device 22a of the yarn monitoring unit 22 without acquiring the yarn defect data from the control device 22b of the yarn monitoring unit 22. In this case, the processing unit 42 can calculate yarn defect data from the acquired waveform data.

In the above embodiment, the machine body control device 4 executes both the first clearing simulation and the second clearing simulation, but the second clearing simulation does not necessarily have to be executed. When the body control device 4 causes the touch panel 41 to display the provisional clearing threshold, it is not necessary to display the section 52a selected by the operator separately from the other sections. In addition, the body control device 4 does not necessarily have to cause the touch panel 41 to display the current clearing threshold 52 together with the tentative clearing threshold 52.
