Description

Yarn winding device

Technical Field

The present invention relates to a yarn winding apparatus.

Background

A spinning winder (yarn winding device) disclosed in japanese patent application laid-open publication No. 2011-20837 includes a spinning unit, a winding unit, and an automatic bobbin supplying device (bobbin processing device). The spinning unit spins the yarn and winds the yarn around an empty bobbin to form a yarn supply bobbin. The winding unit unwinds the yarn from the yarn feeding bobbin and winds the yarn around the winding bobbin to form a package, and discharges the processed yarn feeding bobbin as a discharge tube. The bobbin processing device performs supply of the yarn feeding bobbin to the winding unit side, predetermined processing for the yarn feeding bobbin and the discharge tube, return of the emptied discharge tube to the spinning unit side, and the like. The yarn feeding bobbin and the like are conveyed in a state of being mounted on the tray.

Here, the discharge pipe may include a "defective bobbin" discharged due to a large number of yarn defects in the yarn or the like. Specifically, the winding unit is configured to be able to determine whether or not the yarn supply bobbin from which the yarn is unwound is a defective bobbin. When the yarn supply bobbin is determined to be a defective bobbin, the winding unit stops unwinding of the yarn from the yarn supply bobbin and discharges the yarn supply bobbin.

The bobbin processing device is configured to temporarily wait for the tray on which the defective bobbin is mounted in the defective bobbin waiting path. The defective bobbin staying on the defective bobbin standby path is pulled out from the tray by an operator and replaced with an empty bobbin. Then, the tray with the empty bobbin attached is carried out of the defective bobbin standby path and returned to the spinning unit.

As described in japanese patent application laid-open No. 2011-20837, it takes labor when an operator pulls out defective bobbins that are standing by on a defective bobbin standby path one by one from a tray. If the above-described drawing operation by the operator is not performed for some reason such as a failure and the tray on the defective bobbin standby path is fully loaded, the subsequent defective bobbin cannot enter the defective bobbin standby path. In such a case, the operation of the bobbin processing device may be stopped.

Disclosure of Invention

The invention aims to draw out a defective bobbin from a tray without depending on manpower when a yarn supplying tube for unwinding yarn by a winding unit is judged to be the defective bobbin.

A yarn winding apparatus according to a first aspect of the present invention includes: a winding unit configured to unwind a yarn from a yarn feeding bobbin attached to a tray and wind the yarn around a winding bobbin, and discharge the processed yarn feeding bobbin as a discharge pipe; a unit control unit for controlling the operation of the winding unit; a monitoring unit that monitors the yarn unwound from the yarn feeding bobbin and traveling; a quality information adding unit configured to add quality information relating to the quality of the yarn wound around the yarn feeding bobbin to a quality information added unit; a bobbin processing device that forms a conveying path for conveying the tray and performs a predetermined process on the yarn feeding bobbin and the discharge pipe; a quality information obtaining unit configured to obtain the quality information of the bobbin of the tray mounted on the conveying path from the quality information providing unit; and a bobbin processing control unit that controls the extracting unit based on the quality information acquired by the quality information acquiring unit, wherein the bobbin processing apparatus further includes a determining unit that determines whether or not the yarn feeding bobbin is a defective bobbin based on a monitoring result of the monitoring unit, the bobbin processing apparatus includes an extracting unit that is capable of extracting a bobbin from the tray, the unit control unit stops unwinding of the yarn from the bobbin by the winding unit and discharges the bobbin from the winding unit when the determining unit determines that the yarn feeding bobbin is the defective bobbin, and the quality information imparting unit imparts information indicating that the discharged bobbin is the defective bobbin to the quality information imparting unit, and the bobbin processing control unit controls the extracting unit based on the quality information acquired by the quality information acquiring unit, and when the discharge pipe is the defective bobbin, the bobbin is drawn out from the tray on which the bobbin is mounted.

In the present invention, the defective bobbin is a bobbin that cannot be distinguished from the normal yarn feeding bobbin by visual observation, but can be distinguished from the normal yarn feeding bobbin by monitoring the yarn unwound from the yarn feeding bobbin and running by the monitoring unit and making a judgment by the judgment unit. For example, a yarn feeder tube around which a yarn that is twisted weakly and is likely to be broken or a yarn feeder tube around which a yarn that has a large number of yarn defects is wound corresponds to a defective bobbin. The yarn feeding bobbin determined to be a defective bobbin is stopped from being used and discharged from the winding unit.

In the present invention, the quality information acquisition unit can acquire the quality information of the bobbin conveyed on the conveying path of the bobbin processing apparatus. Further, since the extracting portion is controlled based on the quality information, the defective bobbin can be extracted from the tray by the extracting portion. Therefore, when the yarn supplying bobbin that unwinds the yarn by the winding unit is determined to be a defective bobbin, the defective bobbin can be pulled out from the tray without depending on the manual power.

In the yarn winding device according to the second aspect of the invention, the monitoring unit includes the determination unit.

For example, a part of the monitoring unit may function as the determination unit, or the cell control unit may function as the determination unit. In the present invention, the load of processing by the cell control unit can be reduced as compared with the case where the cell control unit functions as the determination unit.

In the yarn winding device according to the third aspect of the invention, in the first aspect of the invention, the unit control unit includes the determination unit.

In the present invention, even if the monitoring unit is configured not to function as the determining unit, the unit control unit can determine whether or not the yarn feeding bobbin is a defective bobbin.

A yarn winding device according to a fourth aspect of the invention is the yarn winding device according to any one of the first to third aspects of the invention, wherein the quality information imparting unit is provided in the tray, and the quality information acquiring unit reads the quality information imparted to the tray.

For example, the quality information imparting unit may be configured to be communicable with the control unit, and the control unit may store data relating to the quality information and function as the quality information imparting unit. However, in such a configuration, since data relating to the quality information is concentrated in the control unit, for example, when a failure occurs in the control unit, the data may be lost together. In the present invention, since the quality information is given to each tray, it is possible to avoid concentration of data relating to the quality information in the control section. Thus, the risk of disappearance of the data can be suppressed.

A fifth invention of the yarn winding device is characterized in that, in any one of the first to fourth inventions, the bobbin processing apparatus includes a state information acquisition unit that acquires state information on a state of a bobbin of the tray attached to the conveyance path, the bobbin processing control unit controls the drawing unit based on the state information in addition to the quality information, and draws out the bobbin from the tray when the state information acquired by the state information acquisition unit satisfies a predetermined condition.

In the present invention, the bobbin other than the defective bobbin can be drawn out without depending on the manual power.

A yarn winding device according to a sixth aspect of the invention is the yarn winding device according to the fifth aspect of the invention, further comprising a yarn amount detection unit that detects an amount of the yarn wound around the bobbin attached to the tray, wherein the state information acquisition unit includes the yarn amount detection unit, and the state information includes yarn amount information related to the amount of the yarn.

For example, a discharge pipe in which the yarn is normally unwound by the winding unit and a small amount of the yarn remains may be a target of the yarn withdrawal. In the present invention, such a bobbin can be drawn out by the drawing part.

In the yarn winding device according to a seventh aspect of the invention, in the fifth or sixth aspect of the invention, the bobbin processing device includes: a supply path for conveying the tray on which the yarn feeding bobbin is mounted; a discharge path for conveying the tray on which the discharge pipe is mounted; a yarn threading section for performing yarn threading on a yarn end of the yarn feeding bobbin on the feeding path; a feeding path that branches off from a portion of the supply path downstream of the lead processing unit in a conveying direction of the tray and merges with the discharge path; a return path that branches from a portion of the discharge path on a downstream side of a point of confluence with the discharge path in the conveying direction, and merges with a portion of the supply path on an upstream side of the lead wire processing unit; a number-of-times information giving unit configured to give, to a number-of-times information giving unit, number-of-times information in which, when information regarding the number of times the tray is looped around along a loop path formed by the supply path, the delivery path, the discharge path, and the return path is set as the number-of-times information; and a count information obtaining unit configured to obtain the count information given to the count information giving unit, wherein the bobbin processing control unit controls the bobbin processing device to convey the tray on which the yarn feeding bobbin is mounted along the circulating path and return the tray to the supply path when the yarn feeding process for the yarn feeding bobbin fails, and controls the count information giving unit to give the count information to the count information giving unit, and the state information obtaining unit includes the count information obtaining unit and the state information includes the count information.

If the yarn feeding bobbin, which has failed the yarn threading process repeatedly, is wound around the winding path a plurality of times, the tray to which the yarn feeding bobbin is attached may be left on the winding path and may become an obstacle to another tray. In the present invention, such a bobbin can be drawn out by the drawing part.

A yarn winding device according to an eighth aspect of the present invention is the yarn winding device according to any one of the fifth to seventh aspects of the present invention, further comprising a sorting unit configured to process the drawn bobbins drawn out of the tray by the drawing unit so as to be sorted, wherein the bobbin processing control unit controls the sorting unit based on at least the quality information.

In the configuration in which the defective bobbin and the other bobbins can be extracted, the defective bobbin and the other bobbins are preferably classified because the contents of processing to be performed after extraction are different from each other. However, since the defective bobbin is not different from other bobbins in appearance, it is difficult to classify the defective bobbin by human power. In the present invention, the sorting unit can be controlled based on at least information as to whether the drawn-out bobbin is a defective bobbin. Therefore, the defective bobbin can be classified from the other drawn bobbins.

In the yarn winding device according to a ninth aspect of the present invention, in the eighth aspect of the present invention, the sorting unit includes: a plurality of classification paths; and a switching unit capable of switching to which of the plurality of sorting paths the take-out bobbin is moved.

For example, in order to sort a defective bobbin from other bobbins, a label or the like may be attached to the defective bobbin, but for example, in a configuration in which the defective bobbin and other drawn bobbins are to be transported to the same place, the defective bobbin and the other drawn bobbins need to be finally sorted by manpower, which may cause labor. In the present invention, the defective bobbin and the other drawn-out bobbin can be moved to different places from each other. Therefore, the defective bobbin can be easily and reliably classified from the other drawn bobbin.

In the yarn winding device according to the tenth aspect of the invention, in the ninth aspect of the invention, the plurality of sorting paths include a first sorting path and a second sorting path different from the first sorting path, and the switching unit includes: a guide member that is capable of switching between a first position at which the drawn-out bobbin is guided to the first sorting path and a second position at which the drawn-out bobbin is guided to the second sorting path; and a driving unit configured to move the guide member between the first position and the second position.

In the present invention, the drawn-out bobbins can be classified by a simple operation of switching the position of the guide member.

In the yarn winding device according to the eleventh aspect of the invention, in the ninth or tenth aspect of the invention, the plurality of sorting paths extend at least downward as the plurality of sorting paths extend toward a downstream side in a moving direction of the take-out bobbin.

In the present invention, the drawn-out bobbin can be moved along the sorting path by the action of gravity. Therefore, the cost can be reduced compared to a structure in which the bobbin is conveyed and drawn by a mechanism such as a conveyor.

A twelfth aspect of the invention provides the yarn winding apparatus of any one of the ninth to eleventh aspects of the invention, wherein a storage section capable of storing a plurality of the drawn-out bobbins is provided on a downstream side of the sorting path in a moving direction of the drawn-out bobbins.

In the present invention, the plurality of drawn-out bobbins classified and stored can be collected and collectively processed. Therefore, for example, labor can be saved compared to a case where the drawn bobbins on the sorting path are processed one by one.

In the yarn winding device according to the thirteenth aspect of the invention, in any one of the eighth to twelfth aspects of the invention, the bobbin processing control unit controls the classifying unit based on the state information in addition to the quality information.

Depending on the situation, the drawn bobbins other than the defective bobbin may be classified into more groups. In the present invention, the sorting unit is also controlled based on the state information, and therefore the drawn bobbins other than the defective bobbin can be further sorted.

A yarn winding apparatus according to a fourteenth aspect of the invention is the yarn winding apparatus according to any one of the first to thirteenth aspects of the invention, including a spinning frame connected to the bobbin handling device, the spinning frame including a spinning unit that spins a yarn and winds the yarn around an empty bobbin to form the yarn feeding bobbin, the bobbin handling device including: an empty bobbin mounting part for mounting an empty bobbin on the tray from which the bobbin is drawn out by the drawing part; and a return path for returning the tray on which the empty bobbin is mounted to the spinning machine.

In the present invention, in the yarn winding device in which the bobbin handling device is connected to the spinning machine, the operation until the defective bobbin is drawn out from the tray, the empty bobbin is mounted on the tray, and the tray on which the empty bobbin is mounted is returned to the spinning machine can be performed without depending on the manual labor.

A fifteenth aspect of the invention provides the yarn winding device of any one of the first to thirteenth aspects of the invention, wherein the bobbin processing apparatus includes a bobbin supply mounting portion for mounting a bobbin supply to the tray after the bobbin is drawn out by the draw-out portion.

In the yarn winding device of the present invention, the yarn supplying bobbin is mounted on the empty tray and is conveyed to the winding unit again, and the operation until the defective bobbin is drawn out from the tray and the yarn supplying bobbin is mounted on the tray can be performed without depending on manpower.

A sixteenth aspect of the present invention provides the yarn winding device of the fifteenth aspect of the present invention, wherein a yarn amount detection unit that detects an amount of the yarn wound around the bobbin is provided, and the bobbin processing control unit controls the drawing unit to draw out an empty bobbin from the tray based on yarn amount information related to the amount of the yarn in addition to the quality information.

In the present invention, both the defective bobbin and the empty bobbin can be drawn out by the drawing part. Therefore, the manufacturing cost of the yarn winding device can be reduced as compared with a structure in which the bobbins are drawn out separately.

Detailed Description

An embodiment of the present invention will be described below with reference to fig. 1 to 11. For convenience of explanation, the directions shown in fig. 1 are the front-back direction and the left-right direction. The direction (vertical direction) in which gravity acts, which is orthogonal to both the front-back direction and the left-right direction, is defined as the up-down direction.

(brief Structure of yarn winding device)

First, a schematic configuration of the yarn winding device 1 according to the present embodiment will be described with reference to fig. 1 and 2. Fig. 1 is a schematic plan view of a yarn winding device 1 according to the present embodiment. Fig. 2 is a block diagram showing an electrical configuration of the yarn winding apparatus 1. As shown in fig. 1, the yarn winding device 1 includes a spinning machine 2, a bobbin processing device 3, a winding machine 4, and a machine body control device 5. The yarn winding apparatus 1 is a so-called Link core type apparatus in which a spinning frame 2, a bobbin processing device 3, and a winder 4 are connected together.

The spinning frame 2 has a plurality of spinning units 6 arranged in the left-right direction. Each spinning unit 6 spins a roving, not shown, and winds the roving around a cylindrical empty bobbin to form a yarn feeding bobbin Bs. The spinning machine 2 feeds the yarn feeding bobbin Bs formed by each spinning unit 6 into the bobbin handling device 3. The yarn feeding bobbin Bs is attached to the tray T and fed into the bobbin processing apparatus 3 in a substantially upright state. The tray T is provided with an RF tag 100 (see fig. 3 and 4) capable of recording various information such as identification information of the tray T.

The bobbin processing device 3 is configured to convey a tray T, to which a yarn supply bobbin Bs (see a black circle in fig. 1) formed by the spinning machine 2 is attached, toward the winding machine 4, and convey a tray T, to which a discharge pipe Bd (see a white circle in fig. 1) discharged from the winding machine 4 is attached, toward the spinning machine 2. Hereinafter, the yarn feeding bobbin Bs and the discharge tube Bd are collectively referred to as a bobbin B. The bobbin processing device 3 is disposed on the left side of the spinning machine 2 and on the right side of the winder 4. The bobbin processing device 3 has a conveying path 10 for conveying the tray T with the bobbin B attached thereto. The bobbin processing device 3 performs a predetermined process on the bobbin B. The bobbin processing device 3 performs, for example, a threading process for facilitating the catching of the yarn end of the yarn feeding bobbin Bs by the winding unit 7 described later, a drawing process of the discharge tube Bd (described later in detail), and the like.

The winder 4 is disposed on the left of the bobbin processing device 3. The winder 4 has a plurality of winding units 7 arranged in the left-right direction. Each winding unit 7 unwinds the yarn from the yarn supplying bobbin Bs and winds the yarn around the winding bobbin Bw (see fig. 3) to form a package P (see fig. 3). Each winding unit 7 discharges the treated yarn supplying tube Bs as a discharge tube Bd. The discharge tube Bd includes an empty bobbin after the yarn is completely unwound and a bobbin base yarn bobbin (details will be described later) in which the yarn remains. The winding machine 4 includes a supply path 101, a plurality of individual paths 102, and a discharge path 103. The supply path 101 is a path for conveying the tray T on which the yarn feeding bobbin Bs is mounted, which is disposed behind each winding unit 7 and extends in the left-right direction. Each individual path 102 is a path branched from the supply path 101 and extending forward to distribute the yarn feeding bobbin Bs to each winding unit 7. The discharge path 103 is a path joining the individual paths 102 and extending in the left-right direction for returning the tray T to which the discharge pipe Bd is attached to the bobbin processing apparatus 3. The trays T on the respective paths are conveyed by a conveying mechanism not shown.

The body control device 5 is disposed on the left of the winder 4. As shown in fig. 2, the body control device 5 is electrically connected to a control unit (not shown) of each spinning unit 6, a bobbin processing control unit 11 of the bobbin processing device 3, and a unit control unit 12 of each winding unit 7, and performs communication with these control units.

In the yarn winding apparatus 1 having the above configuration, the yarn feeding bobbin Bs formed by the spinning machine 2 is supplied to each winding unit 7 of the winder 4 via the bobbin processing device 3. The yarn is unwound from the yarn supply bobbin Bs by each winding unit 7. The processed yarn supply bobbin Bs is discharged from each winding unit 7 as a discharge tube Bd, and is returned to the spinning frame 2 via the bobbin processing device 3.

(winding unit)

Next, the structure of the winding unit 7 will be described in brief with reference to fig. 3. Fig. 3 is a schematic front view of the winding unit 7.

The winding unit 7 is configured to unwind the yarn Y from the yarn supplying bobbin Bs disposed at the lower end portion and wind the yarn Y around the winding bobbin Bw disposed at the upper end portion to form a package P. As shown in fig. 3, the winding unit 7 includes, in order from the lower side, a bobbin supporting portion 21, a clearer 22, and a traverse drum 23. The winding unit 7 unwinds the yarn Y from the yarn feeding bobbin Bs supported by the bobbin supporting portion 21, monitors the running yarn Y with the yarn clearer 22, and winds the yarn Y around the winding bobbin Bw rotating in contact with the traverse drum 23. The winding bobbin Bw is rotatably supported by the cradle 24.

The bobbin support portion 21 is configured to be able to support the tray T to which the yarn feeding bobbin Bs is attached. The yarn clearer 22 is configured to be able to monitor the yarn Y unwound from the yarn supply bobbin Bs and traveling, and to be able to detect a yarn defect included in the yarn Y. The traverse drum 23 is in contact with the surface of the winding tube Bw (package P), and is rotationally driven by a motor (not shown), thereby rotating the winding tube Bw in contact therewith. The traverse drum 23 is formed with a groove for traversing the yarn Y. In this way, the traverse drum 23 rotates the winding tube Bw while traversing the yarn Y, and winds the yarn Y around the winding tube Bw.

The clearer 22 (monitoring section of the present invention) will be described in more detail. The yarn clearer 22 has, for example, an optical sensor, and detects a yarn defect or the like of the yarn Y by monitoring the yarn Y during travel. The yarn clearer 22 has a cutter, not shown, that cuts the running yarn Y when a yarn defect or the like of the yarn Y is detected. The clearer 22 also includes a clearer control unit 22a (determination unit of the present invention) (see fig. 2). The clearer control section 22a is configured to be able to count the number of yarn defects of the yarn Y, the number of times the yarn Y is cut by the cutter, the number of times of yarn breakage due to a factor other than yarn cutting by the cutter, or the like. For example, when the number of yarn defects or the number of yarn breakage of the yarn Y is equal to or greater than a predetermined value, the clearer control section 22a determines that the yarn supply bobbin Bs from which the yarn Y is unwound is a defective bobbin around which a defective yarn is wound. The clearer control section 22a is electrically connected to the unit control section 12 (see fig. 2) described above. When determining that the yarn feeding bobbin Bs is a defective bobbin, the clearer control section 22a transmits a signal indicating that the yarn feeding bobbin Bs is a defective bobbin to the unit control section 12.

When the yarn is cut by the cutter or the yarn is cut due to another factor, the winding unit 7 performs a yarn splicing process of splicing the yarn Y on the yarn feeding bobbin Bs side (the lower yarn Y1) and the yarn Y on the winding bobbin Bw side (the upper yarn Y2). The winding unit 7 includes a piecing device 25, a lower yarn suction nozzle 26, and an upper yarn suction nozzle 27 as a configuration for performing piecing processing. The lower yarn suction nozzle 26 suctions and holds the lower yarn Y1 and guides it toward the piecing device 25. The upper yarn suction nozzle 27 sucks and holds the upper yarn Y2 and guides it toward the yarn splicing device 25. The joint device 25 performs joint by using compressed air, for example. The yarn splicing device 25 performs yarn splicing by blowing compressed air to the lower yarn Y1 and the upper yarn Y2 to temporarily unravel both ends, and then blowing compressed air to both ends again to entangle the ends with each other.

Further, a reading/writing unit 28, a yarn presence sensor 29, and an injector 30 are disposed in the vicinity of the bobbin supporting unit 21. The read/write unit 28 is electrically connected to the cell control unit 12 (see fig. 2). The reading and writing unit 28 is configured to be able to write quality information relating to the quality of the yarn feeding bobbin Bs to the RF tag 100 (see fig. 1) of the tray T. For example, when the yarn feeding bobbin Bs is determined to be a defective bobbin, the unit control section 12 controls the read/write section 28 to record quality information indicating that the yarn feeding bobbin Bs is a defective bobbin in the RF tag 100. That is, the RF tag 100 corresponds to the quality information providing unit of the present invention. The read/write unit 28 corresponds to the quality information providing unit of the present invention. The yarn presence sensor 29 detects whether or not the yarn feeding bobbin Bs is in a state in which the yarn Y can be unwound. The ejector 30 is configured to be able to discharge the yarn feeding bobbin Bs from the winding unit 7. For example, when the yarn Y drawn out from the yarn feeding bobbin Bs cannot be detected by the yarn presence sensor 29, the winding unit 7 determines that the yarn that becomes the yarn feeding bobbin Bs is used up (empty) or the yarn of the yarn feeding bobbin Bs is in a state where it cannot be caught, and operates the ejector 30 to discharge the yarn feeding bobbin Bs from the winding unit 7. When the yarn clearer 22 determines that the yarn feeding bobbin Bs is a defective bobbin, the unit control unit 12 stops unwinding of the yarn Y from the yarn feeding bobbin Bs and discharges the yarn feeding bobbin Bs from the winding unit 7 by the ejector 30. The discharged bobbin B (discharge tube Bd) passes through a downstream portion in the conveyance direction of the individual path 102 and is conveyed toward the discharge path 103.

As described above, the winding unit 7 includes the unit control unit 12. The unit control unit 12 includes a CPU, ROM, RAM, and the like. The unit control unit 12 controls each unit of the winding unit 7 by the CPU based on a program stored in the ROM. The unit control unit 12 performs communication with the body control device 5.

(Structure of bobbin treatment device)

Next, a more detailed configuration of the bobbin processing device 3 will be described with reference to fig. 4 and (a) to (c) of fig. 5. Fig. 4 is a plan view of the bobbin processing apparatus 3. Fig. 5 (a) is a perspective view of a bobbin extracting device 42 and a bobbin sorting device 45, which will be described later. Fig. 5 (b) is a front view of the bobbin drawing device 42. Fig. 5 (c) is a front view of the bobbin sorting device 45.

The bobbin handling device 3 is configured to convey the tray T with the yarn feeding bobbin Bs attached thereto from the spinning machine 2 to the winding machine 4, and to return the tray T with the discharge tube Bd attached thereto from the winding machine 4 to the spinning machine 2. The bobbin processing device 3 is configured to perform predetermined processing on the yarn feeding bobbin Bs and the discharge bobbin Bd.

As shown in fig. 4, the bobbin processing device 3 has a substantially rectangular shape when viewed from above. The bobbin processing device 3 has the conveyance path 10 as described above. The conveyance path 10 includes a supply path 31, a discharge path 32, a delivery path 33, and a return path 34. The supply path 31 is a path extending over both the left and right ends of the bobbin processing device 3 and used for conveying the yarn feeding bobbin Bs to the winder 4 side. The left end of the supply path 31 is connected to the right end of the supply path 101 of the winder 4. The discharge path 32 is a path extending over both the left and right ends of the bobbin processing device 3 and conveying the discharge tube Bd toward the spinning machine 2, similarly to the supply path 31. The left end of the discharge path 32 is connected to the right end of the discharge path 103 of the winder 4.

The feeding path 33 (see the left hatched portion of the paper in fig. 4) branches off from a portion of the supply path 31 on the downstream side of the lead device 41 (described later) in the transport direction of the tray T (hereinafter, simply referred to as the transport direction). The delivery path 33 merges with the discharge path 32. An arrival-destination switching unit 35 capable of switching the arrival destination of the tray T is provided at a branching point between the supply path 31 and the delivery path 33. The destination switching unit 35 is electrically connected to the bobbin processing control unit 11 (see fig. 2). The return path 34 (see the hatched portion on the right side of the paper in fig. 4) branches off from a portion of the discharge path 32 on the downstream side in the conveyance direction from the point of merger with the delivery path 33. The return path 34 merges with a portion of the supply path 31 on the upstream side in the conveyance direction of the wire-drawing device 41. An outgoing destination switching unit 36 capable of switching the outgoing destination of the tray T is provided at a branching point between the discharge path 32 and the return path 34. The destination switching unit 36 is electrically connected to the bobbin processing control unit 11 (see fig. 2). A circulating path 37 around which the tray T can circulate is formed by a part of the supply path 31, the delivery path 33, a part of the discharge path 32, and the return path 34. The trays T on the conveying path 10 are conveyed in the direction indicated by the arrow in fig. 4 by a conveying mechanism, not shown.

The bobbin processing device 3 is provided with a device for performing a predetermined process on the bobbin B on the conveyance path 10. Specifically, the yarn feeding device includes a yarn feeding device 41 for performing a yarn feeding process of the yarn end of the yarn feeding bobbin Bs, a bobbin drawing device 42 for drawing the discharge tube Bd from the tray T, and a bobbin mounting device 43 for mounting the bobbin B on the empty tray T.

As shown in fig. 4, the wire-bonding device 41 (wire-bonding processing unit of the present invention) is disposed along the supply path 31. The yarn threading device 41 is a device for performing yarn threading processing on the yarn end of the yarn feeding bobbin Bs conveyed on the feeding path 31. The lead wire treatment means: the yarn end wound around the yarn feeding bobbin Bs is drawn out, and the yarn end of the yarn feeding bobbin Bs is easily sucked and caught by the lower yarn suction nozzle 26 in the winding unit 7 (see fig. 3). The wire feeding device 41 is electrically connected to the bobbin processing control unit 11 (see fig. 2). A yarn amount sensor 44 for detecting the amount of the yarn wound around the yarn feeding bobbin Bs is disposed near the yarn feeding device 41. The yarn amount sensor 44 is electrically connected to the bobbin processing controller 11 (see fig. 2).

When the amount of the yarn detected by the yarn amount sensor 44 is sufficient, the bobbin processing control unit 11 controls the yarn threading device 41 to thread the yarn on the yarn feeding bobbin Bs on which the yarn is wound. When the thread guiding process is successful, the tray T with the yarn feeding bobbin Bs attached thereto is conveyed toward the winding machine 4 through the supply path 31. When the wire bonding process fails or is not performed, the tray T is guided to the feeding path 33 side by the destination switching unit 35 and passes through the circulating path 37 (described in detail later).

The bobbin extracting device 42 (extracting portion of the present invention) is disposed along the return path 34. The bobbin drawing device 42 is a device mainly for drawing the discharge tube Bd from the tray T. The bobbin drawing device 42 is disposed to extend in the vertical direction (see fig. 5 (a)). Further, a bobbin sorting device 45 (see fig. 5 (a)) is connected to the bobbin extracting device 42. The bobbin sorter 45 will be described in detail later.

As shown in fig. 4, near the branching point of the discharge path 32 and the return path 34, a package yarn sensor 46 that detects whether or not a yarn remains in the discharge tube Bd is arranged. The yarn package sensor 46 is electrically connected to the bobbin processing control unit 11 (see fig. 2). For example, when no yarn is detected by the package foot yarn sensor 46, the tray T is returned toward the spinning machine 2 through the discharge path 32. When the yarn is detected by the yarn foot sensor 46, the tray T is guided to the return path 34 side by the destination switching section 36.

A yarn amount sensor 47 for detecting the amount of the yarn remaining in the discharge tube Bd is disposed in a portion between the bobbin extracting device 42 and the package foot yarn sensor 46 in the conveyance direction. Different processes (details will be described later) are performed in the bobbin drawing device 42 based on the detection result of the yarn amount sensor 47.

Further, a reading/writing unit 48 for reading information from the RF tag 100 recorded on the tray T or writing information to the RF tag 100 is disposed in the vicinity of the yarn amount sensor 47. The read/write unit 48 is electrically connected to the bobbin processing control unit 11 (see fig. 2).

The bobbin mounting device 43 (an empty bobbin mounting portion of the present invention) is disposed downstream of the bobbin withdrawing device 42 in the conveying direction. The bobbin mounting device 43 is configured to be able to mount an empty bobbin B on a tray T from which the bobbin B is drawn out and emptied.

As described above, the bobbin processing device 3 includes the bobbin processing control unit 11. The bobbin processing control unit 11 includes a CPU, ROM, RAM, and the like. The bobbin processing control unit 11 controls each unit of the bobbin processing device 3 by the CPU in accordance with a program stored in the ROM. The bobbin processing controller 11 performs communication with the body control device 5.

Here, in the conventional bobbin processing apparatus, a standby path branched from the discharge path 32 is formed, and a defective bobbin is caused to stand by on the standby path. The defective bobbins standing by on the standby path are pulled out one by one from the tray T by the operator and replaced with empty bobbins. It takes much labor to perform such an operation. If the above-described drawing operation by the operator is not performed for some reason such as a failure or the like, and the tray T on the standby path is fully loaded, the subsequent defective bobbin cannot enter the standby path. In such a case, the operation of the bobbin processing device 3 may be stopped. Therefore, in the present embodiment, the yarn winding apparatus 1 has a structure such that, when it is determined that the yarn supplying bobbin Bs from which the yarn is unwound by the winding unit 7 is a defective bobbin, the defective bobbin can be drawn out from the tray T without depending on manpower.

(bobbin withdrawing device)

First, a specific configuration of the bobbin drawing device 42 will be described with reference to fig. 5 (a) to (c). As shown in fig. 5 (b), the bobbin extracting device 42 includes: a conveying mechanism 51; the squeeze rollers 52; and 2 guide members 53 arranged in an up-down direction. In addition, the number of the guide members 53 is not limited thereto. The bobbin withdrawing device 42 may include 3 guide members 53 as in the embodiment described below. The conveying mechanism 51 has

belt conveying rollers

54, 55 disposed apart from each other in the vertical direction; and an endless belt 56 wound around the

belt conveying rollers

54 and 55. The tape conveying roller 54 is rotationally driven by a motor 57. Thereby, the endless belt 56 is driven, and the belt conveying roller 55 is driven to rotate. The left-side portion (the side facing the return path 34) of the endless belt 56 travels upward.

The pressing roller 52 and the guide member 53 are members for extracting the bobbin B from the tray T by pressing the bobbin B toward the traveling endless belt 56. The pressing roller 52 and the guide member 53 (guide member 61) disposed at the lowermost position are supported by a support member 64 provided independently of the conveyance mechanism 51 via a link mechanism 65. The pressing roller 52 and the guide member 61 are formed so as to be movable between a first position (see solid lines) and a second position (see two-dot chain lines) by a link mechanism 65. The guide member 61 connected to the link mechanism 65 is moved between the first position and the second position by, for example, an air cylinder 67. The air cylinder 67 is configured to be controllable by the bobbin processing control unit 11. When the pressing roller 52 and the guide member 61 are positioned at the first position, the bobbin B is pressed toward the endless belt 56 and drawn out from the tray T. When the pressing roller 52 and the guide member 61 are located at the second position, the bobbin B is not pressed against the endless belt 56, and therefore the bobbin B is not drawn out from the tray T.

The guide member 53 (guide member 62) disposed immediately above the guide member 61 is supported by the support member 64 via the link mechanism 66. The guide member 62 is configured to be movable by a link mechanism 66 so as to change a gap with the endless belt 56. The guide member 62 is closed by a rightward urging force generated by a spring 68 via a link mechanism 66. Thereby, the bobbin B can be sandwiched between the guide member 62 and the endless belt 56. The gap between the guide member 62 and the endless belt 56 can be changed according to the thickness of the bobbin B (for example, according to the presence or absence of the yarn). The bobbin B drawn out from the tray T and conveyed upward is conveyed to above the guide member 62. The bobbin B transported to the upper side of the guide member 62 falls obliquely downward to the left (see the arrow in fig. 5B). In the present embodiment, all the drawn-out bobbins Bp drawn out by the bobbin drawing-out device 42 move toward the bobbin sorting device 45.

(bobbin sorting device)

Next, the bobbin sorting device 45 will be explained. As shown in fig. 5 (a), a bobbin sorting device 45 (sorting unit of the present invention) is connected to the bobbin extracting device 42. The bobbin sorter 45 is a device that performs processing so as to sort the drawn bobbins B (hereinafter also referred to as drawn bobbins Bp) into a plurality of types. The bobbin sorter 45 is disposed on the left side of the bobbin drawing device 42 (the side from which the drawn bobbin Bp is dropped off from the bobbin drawing device 42). As shown in fig. 5 (c), the bobbin sorter 45 includes a frame member 71 and a switching mechanism 72.

The frame member 71 is a member formed with an internal passage through which the extraction bobbin Bp passes. As shown in fig. 5 (c), the frame member 71 includes: an inlet 73 into which the drawn-out bobbin Bp dropped off from the bobbin sorter 45 is inserted; a common path 74; and a plurality of sort paths 75 (a first sort path 76 and a second sort path 77). The common path 74 is formed at an upper portion of the frame member 71. The common path 74 extends obliquely downward to the left. The drawn-out bobbin Bp can fall along the inclined portion of the common path 74. The first sorting path 76 and the second sorting path 77 are disposed below the common path 74 (downstream side in the moving direction of the drawn-out bobbin Bp). The first sorting path 76 and the second sorting path 77 are separated from each other by a partition member 78. The exit portions of the first sorting path 76 and the second sorting path 77 are bent and extend obliquely downward (see fig. 5 (a)). That is, the first sorting path 76 and the second sorting path 77 extend at least downward as they go downstream in the moving direction of the drawn-out bobbin Bp. A first discharge box 111 is disposed downstream of the first sorting path 76 and a second discharge box 112 is disposed downstream of the second sorting path 77 in the moving direction of the drawn-out bobbin Bp. The first discharge box 111 and the second discharge box 112 are configured to be capable of storing a plurality of drawn-out bobbins Bp. The first discharge box 111 and the second discharge box 112 correspond to the reservoir unit of the present invention.

The switching mechanism 72 (switching unit of the present invention) is a mechanism for switching to which sorting path 75 the drawn-out bobbin Bp is moved from the common path 74. As shown in fig. 5 (c), the switching mechanism 72 includes, for example, a rotating plate 81, a guide plate 82 (guide member of the present invention), and an air cylinder 83 (drive unit of the present invention). The switching mechanism 72 is configured to switch the destination of the drawn-out bobbin Bp by switching the position (angular position) of a guide plate 82 fixed to a rotatable rotating plate by an air cylinder 83.

The rotating plate 81 is provided above the partition member 78, and is rotatably supported by the frame member 71. The end surface of the rotating plate 81 is provided with, for example, a projection 84. A tip end portion of a rod 85 of the cylinder 83 is attached to the rotating plate 81 via a projection. The guide plate 82 is provided to be rotatable integrally with the rotating plate 81. The cylinder 83 has a rod 85 capable of extending and contracting. The front end of the lever 85 is attached to the protrusion 84 of the rotating plate 81. The cylinder 83 is configured to expand and contract the rod 85 by supplying and discharging compressed air. The pivotal plate 81 pivots by the expansion and contraction of the lever 85, and thereby the position (angular position) of the guide plate 82 is switched. Specifically, the guide plate 82 can switch the position between a first position (see a solid line in fig. 5 (c)) at which the drawn-out bobbin Bp is guided to the first sorting path 76 and a second position (see a two-dot chain line in fig. 5 (c)) at which the drawn-out bobbin Bp is guided to the second sorting path 77. The cylinder 83 is configured to be controllable by the bobbin processing control unit 11.

(control relating to bobbin extraction processing)

Next, the drawing process of drawing out the bobbin B from the tray T conveyed on the conveying path 10 of the bobbin processing device 3 will be described. In the present embodiment, as will be described later, the bobbin processing control unit 11 controls the respective parts of the bobbin processing device 3, and the bobbin drawing device 42 draws out a plurality of types of bobbins B from the tray T, and the bobbin sorting device 45 sorts the drawn-out bobbins Bp.

First, before describing the control of the bobbin processing device 3 by the bobbin processing control section 11, the discharge processing of discharging the tray T from the winding unit 7 by the unit control section 12 will be described with reference to a flowchart shown in fig. 6.

As an initial state, in the winding unit 7, the yarn Y is unwound from the yarn supplying tube Bs. When the yarn feeding bobbin Bs is not judged to be a defective bobbin on which a defective yarn is wound by the detection result of the yarn clearer 22 (see fig. 2) (S101: no), the unit control section 12 causes the winding unit 7 to continue unwinding the yarn from the yarn feeding bobbin Bs. When the yarn supplying bobbin Bs is not empty (S102: no), the process returns to S101 to wait for a signal from the yarn clearer 22. When the bobbin base yarn sensor 46 detects that the yarn feeding bobbin Bs is empty (S102: yes), the unit control section 12 controls the ejector 30 (see fig. 3) to discharge the tray T with the empty yarn feeding bobbin Bs from the winding unit 7 (S103). In addition, while the discharge tube Bd normally discharged as described above is often an empty bobbin in which no yarn remains, a part of the discharge tube Bd may be a small bobbin in which a small amount of yarn remains.

On the other hand, when the yarn feeding bobbin Bs is determined to be a defective bobbin based on the detection result of the yarn clearer 22 before the yarn feeding bobbin Bs becomes empty (S101: yes), the unit control section 12 stops the unwinding process of unwinding the yarn Y from the yarn feeding bobbin Bs by the winding unit 7. The unit control unit 12 controls the read/write unit 28 (see fig. 3) to record quality information indicating that the yarn feeding bobbin Bs is a defective bobbin in the RF tag 100 (see fig. 3) of the tray T (S104). Then, the unit control unit 12 controls the ejector 30 (see fig. 3) to discharge the tray T, to which the empty yarn feeding bobbin Bs (discharge pipe Bd) is attached, from the winding unit 7 (S103).

As described above, when the unwinding of the yarn Y from the yarn feeding bobbin Bs is normally completed, the RF tag 100 of the discharged tray T does not have the quality information indicating that the discharge tube Bd is a defective bobbin written therein. On the other hand, when the yarn feeding bobbin Bs is a defective bobbin, the RF tag of the discharged tray T is written with quality information indicating that the discharge tube Bd is a defective bobbin.

Next, the control of the bobbin processing device 3 by the bobbin processing control section 11 will be described with reference to fig. 7 to 11. Fig. 7 is a flowchart showing processing related to the drawing and discharging of the bobbin B and the return of the tray T. In the following description, the tray T to which the yarn feeding bobbin Bs is attached and the tray T to which the discharge tube Bd is attached may be mixed in the conveyance path 10 of the bobbin processing apparatus 3. Therefore, the yarn feeding bobbin Bs and the discharge tube Bd are collectively referred to as a bobbin B unless otherwise specified. Fig. 8 is a flowchart showing the processing from the time when the tray T is conveyed toward the lead device 41 side to the time when the tray T returns to the conveyance path 10 of the bobbin processing device 3 again. Fig. 9 (a) to (c) and fig. 10 (a) to (c) are explanatory views showing the movement of the bobbin B on the conveyance path 10. Fig. 11 (a) and (b) are explanatory views showing the operation of the bobbin sorting device 45.

As an initial state, the tray T to which a certain bobbin B is attached is positioned in front of the package end yarn sensor 46 on the discharge path 32 (see fig. 9 (a)). Here, the bobbin B conveyed on the discharge path 32 is any one of the defective bobbin, the empty bobbin, the bobbin with a small bobbin base, and the bobbin for the lead wire which needs to be subjected to the lead wire treatment again due to a failure of the lead wire treatment by the lead wire device 41.

First, the bobbin thread sensor 46 detects whether or not a thread remains in the bobbin B. If no yarn remains on the bobbin B (S201: no), the bobbin B is empty and can be returned to the spinning machine 2. Therefore, the tray T on which the bobbin B is mounted is conveyed on the discharge path 32 (return path of the present invention) as it is (see fig. 9 (B)), and is returned to the spinning machine 2 (S202). When a small amount of yarn remains in the bobbin B (S201: yes), the bobbin processing control section 11 controls the destination switching section 36 to move the tray T to the return path 34 (see fig. 9 (c)).

Next, the amount of yarn remaining in the bobbin B is detected by a yarn amount sensor 47 (yarn amount detecting section of the present invention). The yarn amount information on the amount of the yarn is transmitted from the yarn amount sensor 47 to the bobbin processing control section 11. When the bobbin base yarn amount is not less than the predetermined amount (S202: NO), the bobbin B is a small amount of bobbin base yarn bobbin. In this case, the bobbin processing controller 11 controls the bobbin extracting device 42 to remove the bobbin B from the tray T. The bobbin processing controller 11 controls the bobbin sorting device 45 to position the guide plate 82 at the first position (see fig. 11 a), and moves the drawn bobbin Bp to the first sorting path (S204). Thereby, the drawn-out bobbin Bp moves along the first sorting path 76 by the action of gravity, and is discharged to the first discharge box 111. The bobbin processing control unit 11 controls the bobbin mounting device 43 (the empty bobbin mounting unit of the present invention) to mount an empty bobbin B, on which no yarn is wound, on the tray T, on which no bobbin is mounted (S205).

When the bobbin thread amount is equal to or larger than the predetermined amount (yes in S202), the quality information recorded in the RF tag 100 of the tray T is read by the read/write unit 48 (quality information acquisition unit of the present invention). The bobbin processing control unit 11 determines whether or not quality information indicating that the bobbin B is a defective bobbin is recorded on the tray T (S206). When the quality information is recorded on the tray T (S206: yes), the bobbin processing control unit 11 controls the bobbin extracting device 42 to remove the bobbin B from the tray T. The bobbin processing and controlling unit 11 controls the bobbin sorting device 45 to position the guide plate 82 at the second position (see fig. 11 b), and moves the drawn bobbin Bp to the second sorting path (S207). Thereby, the drawn-out bobbin Bp is discharged to the second discharge box 112. The bobbin process control unit 11 controls the bobbin mounting device 43 to mount the empty bobbin B on the empty tray T (S208).

On the other hand, if the tray T does not record the quality information (S206: no), the bobbin B mounted on the tray T is a bobbin with a large bobbin thread amount although not a defective bobbin. Although there is no problem in the yarn quality, the bobbin B, which has not been replenished with yarn by the winding unit 7 at the time of yarn cutting, is also discharged from the winding unit 7 and conveyed through the return path 34. Such a bobbin B is, for example, a bobbin for a lead wire that is looped around the looping path 37 due to a failure in the lead wire processing performed by the lead wire device 41. Therefore, the bobbin processing control section 11 performs the following processing instead of extracting the bobbin B from the tray T. That is, the bobbin-processing control unit 11 controls the read/write unit 48 (the count-information adding unit and the count-information acquiring unit of the present invention) to record the loop information on the number of times the tray T is looped on the RF tag 100 of the tray T (the count-information adding unit of the present invention). More specifically, when the number of times of winding before recording is N times, the bobbin-processing control unit 11 controls the read/write unit 48 to write the number-of-times information indicating that the number of times of winding is N +1 times to the RF tag 100 (S209). When the number of times of winding the tray T is equal to or greater than a predetermined number of times (e.g., 3 times) (yes in S210), the bobbin processing control unit 11 controls the bobbin extracting device 42 to remove the bobbin B from the tray T. The bobbin processing controller 11 controls the bobbin sorting device 45 so that the guide plate 82 is positioned at the first position and the drawn bobbin Bp is discharged to the first discharge box 111 (S211). Then, the bobbin process control unit 11 controls the bobbin mounting device 43 to mount the empty bobbin B on the tray T that has become empty (S212).

In this way, the bobbin process control unit 11 controls the bobbin drawing device 42 based on the quality information, the yarn amount information, and the count information, and executes the process of drawing the bobbin B when the information satisfies a predetermined condition. The yarn amount information and the number of times information correspond to the state information of the present invention. The yarn amount sensor 47 and the read/write section 48 correspond to a state information acquisition section of the present invention. The bobbin processing controller 11 controls the bobbin sorting device 45 based on at least the quality information. That is, the bobbin processing controller 11 discharges the drawn-out bobbin Bp to the first discharge box 111 when the drawn-out bobbin Bp is not a defective bobbin, and discharges the drawn-out bobbin Bp to the second discharge box 112 when the drawn-out bobbin Bp is a defective bobbin.

Then, the bobbin processing control unit 11 moves the tray T from the return path 34 to the supply path 31 (see fig. 10 (a)). That is, the tray T is conveyed toward the lead device 41 (S213). Then, the tray T is fed toward the winding unit 7 or returned to the discharge path 32 again through the circulating path 37 depending on the state of the bobbin B. The specific processing will be described mainly with reference to fig. 8.

First, the yarn amount sensor 44 detects the amount of yarn at the bobbin end of the bobbin B attached to the tray T conveyed through the supply path 31. The bobbin processing control section 11 determines whether or not the yarn amount at the bobbin foot of the bobbin B is equal to or more than a predetermined amount (S301). Here, when the bobbin B is an empty bobbin mounted on the tray T by the bobbin mounting device 43, the bobbin thread amount is inevitably equal to or less than a predetermined amount (S301: no). In this case, the bobbin processing control unit 11 controls the destination switching unit 35 to move the tray T to the delivery path 33 (see fig. 10 (b)). The tray T with the empty bobbin B attached thereto is conveyed to the discharge path 32, and is returned to the spinning machine 2 as it is (see fig. 9 (B)).

On the other hand, when the yarn amount at the bobbin foot of the bobbin B is equal to or more than the predetermined amount (yes in S301), that is, when the bobbin B is a bobbin for yarn guiding to be subjected to yarn guiding processing, the bobbin processing control section 11 controls the yarn guiding device 41 to perform yarn guiding processing on the bobbin B (S303). When the wire leading process is successful (yes in S304), the bobbin processing control unit 11 moves the tray T toward the winding machine 4 as it is (S305, see fig. 10 (c)). When the wire-leading process fails (no in S304), the bobbin-processing control unit 11 controls the destination-switching unit 35 to move the tray T to the delivery path 33 (see fig. 10 (b)). The tray T moving to the feeding path 33 is conveyed to the discharging path 32 again (see fig. 9 (a)).

As described above, the quality information of the bobbin B conveyed on the conveyance path 10 of the bobbin processing apparatus 3 can be acquired by the read/write unit 48. Further, since the bobbin extracting device 42 is controlled based on the quality information, the defective bobbin can be extracted from the tray T by the bobbin extracting device 42. Therefore, when it is determined that the yarn supplying bobbin Bs from which the yarn is unwound by the winding unit 7 is a defective bobbin, the defective bobbin can be drawn out from the tray T without depending on the manual labor.

Then, the clearer control section 22a of the clearer 22 determines whether or not the yarn feeding bobbin Bs is a defective bobbin. Therefore, the load of the processing of the cell control unit 12 can be reduced as compared with the case where the cell control unit 12 functions as the determination unit of the present invention.

Further, since the quality information is given to each tray T, it is possible to avoid concentration of data relating to the quality information on the bobbin processing control unit 11. Thus, the risk of disappearance of the data can be suppressed.

The bobbin extracting device 42 is controlled based on the state information in addition to the quality information. Therefore, the bobbin B other than the defective bobbin can be drawn out without depending on the manual power.

Further, the bobbin extracting device 42 is controlled based on the yarn amount information. Therefore, the discharge tube, in which the yarn is normally unwound by the winding unit 7 and a small amount of yarn remains, can also be drawn out by the bobbin drawing device 42.

The bobbin extracting device 42 is also controlled based on information on the number of times the tray T is looped around the conveyance path 10. Therefore, even a bobbin in which the lead wire process has failed repeatedly can be drawn out by the bobbin drawing device 42.

The bobbin sorting device 45 can be controlled based on at least information as to whether or not the drawn-out bobbin Bp is a defective bobbin. Therefore, the defective bobbin can be classified from the other drawn-out bobbin Bp.

Further, the defective bobbin and the other drawn-out bobbin Bp can be moved to different positions by the plurality of sorting paths 75. Therefore, the defective bobbin and the other drawn-out bobbin Bp can be easily and reliably classified.

Further, the extraction bobbin Bp can be classified by a simple operation of switching the position of the guide plate 82.

The extraction bobbin Bp can be moved along the sorting path 75 by the action of gravity. Therefore, the cost can be reduced compared to a configuration in which the drawn-out bobbin Bp is conveyed along the sorting path 75 by a mechanism such as a conveyor.

Then, the drawn-out bobbin Bp is discharged to the first discharge box 111 or the second discharge box 112. This enables the plurality of drawn-out bobbins Bp classified and stored to be collected and collectively processed. Therefore, for example, labor can be saved compared to the case where the drawn-out bobbins Bp on the sorting path 75 are processed one by one.

In the yarn winding device 1 in which the bobbin handling device 3 is connected to the spinning machine 2, the operation of drawing out a defective bobbin from the tray T and mounting an empty bobbin on the tray T until returning the tray T with the empty bobbin mounted thereon to the spinning machine 2 can be performed without depending on manpower.

Next, a modified example of the above embodiment will be described. However, the same reference numerals are given to those portions having the same configurations as those of the above-described embodiment, and the description thereof is omitted as appropriate.

(1) In the above embodiment, all the drawn-out bobbins Bp drawn out by the bobbin drawing-out device 42 are moved toward the bobbin sorting device 45, but the present invention is not limited thereto. Hereinafter, description will be given using fig. 12 (a) to (c) and fig. 13.

As shown in fig. 12 (a) and (b), a guide member 91 may be provided further above the guide member 62 of the bobbin withdrawing device 42. The guide member 91 is supported by the support member 64 via a link mechanism 92. The guide member 91 connected to the link mechanism 92 is movable between a first position (see the two-dot chain line in fig. 12 a) and a second position (see the solid line in fig. 12 a) by an air cylinder 93, for example. The air cylinder 93 is configured to be controllable by the bobbin processing control unit 11. When the guide member 91 is located at the second position (see fig. 12 a), the drawn-out bobbin Bp drops out toward the bobbin sorting device 45 from the gap formed between the guide member 62 and the guide member 91. On the other hand, when the guide member 91 is at the first position (see fig. 12 b), the draw-out bobbin Bp is pressed against the endless belt 56 by the guide member 91. Thereby, the drawn-out bobbin Bp is moved to the uppermost part of the bobbin drawing-out device 42 by the endless belt 56. In this case, the bobbin drawing device 42 also functions as the sorting unit of the present invention. That is, the path of the drawn-out bobbin Bp formed by the guide member 91 and the endless belt 56 also corresponds to the sorting path of the present invention. In this way, a third sorting path may be formed by the bobbin extracting device 42. Like the switching mechanism 72, the guide member 91, the link mechanism 92, and the cylinder 93 also correspond to the switching unit of the present invention. As shown in fig. 12 (c), a third discharge box 113 may be attached to an upper portion of the bobbin withdrawing device 42. The third discharge box 113 is a discharge destination of the drawn-out bobbin Bp reaching the uppermost portion of the bobbin drawing device 42.

In the above-described configuration, the bobbin processing controller 11 may perform the following control as shown in fig. 13. That is, in the above-described S210, when the number of times of winding of the tray T is equal to or more than the predetermined number of times (yes in S210), the bobbin processing control unit 11 controls the bobbin extracting device 42 to remove the bobbin B from the tray T. The bobbin processing controller 11 controls the bobbin drawing device 42 to position the guide member 91 at the first position and to discharge the drawn bobbin Bp to the third discharge box 113 (S214). That is, the bobbin-processing controller 11 may control the sorting unit based on the quality information and the state information. This enables the drawn-out bobbin Bp other than the defective bobbin to be further classified.

(2) In the modification (1), the third classification path is formed by the bobbin drawing device 42, but the present invention is not limited thereto. For example, the bobbin sorting device 45 may have 3 or more sorting paths and a switching unit capable of switching to which of the 3 or more sorting paths the drawn bobbin Bp is moved.

(3) As a yarn winding device including the bobbin drawing device 42 described in the modification (1), the present invention may be applied to a yarn winding device 1a including a bobbin processing device 3a shown in fig. 14, instead of the yarn winding device 1. The yarn winding device 1a is a device with a yarn supply bobbin feeder, which is not connected to the bobbin processing device 3a and the spinning machine 2 (see fig. 1). The conveyance path 10a of the bobbin processing device 3a includes a supply path 31a, a discharge path 32a, a delivery path 33a, and a return path 34 a. The supply path 31a, the discharge path 32a, the delivery path 33a, and the return path 34a form a circulating path 37 a. As a difference from the bobbin processing device 3 (see fig. 4), the supply path 31a and the return path 34a are not branched from each other, and the discharge path 32a and the return path 34a are also not branched from each other. That is, the bobbin processing device 3a is different from the bobbin processing device 3 in that the delivery of the tray T to the spinning machine 2 is not performed. The bobbin mounting device 43a (yarn feeding bobbin mounting portion of the present invention) of the bobbin processing device 3a is configured to be able to mount a full yarn feeding bobbin Bs to an empty tray T instead of mounting an empty bobbin B to the empty tray T.

In the above-described configuration, the bobbin processing control unit 11 may perform the following control. That is, the bobbin processing control unit 11 may draw out the empty bobbin by the bobbin drawing device 42 in addition to the defective bobbin, the small bobbin yarn bobbin, and the bobbin for the yarn threading as described above. In this case, the yarn feeding bobbin Bs is attached to the empty tray T. Hereinafter, the description will be specifically made with reference to fig. 15. When the bobbin B does not have yarn left in the bobbin B in S201 (no in S201), that is, when the bobbin B is empty, the bobbin processing controller 11 controls the bobbin extracting device 42 to extract the bobbin B and discharge the bobbin B to the third discharge box 113 (S215). The bobbin processing controller 11 controls the bobbin mounting device 43a to mount the yarn feeding bobbin Bs on the empty tray T (S216). Similarly, when a small number of the bobbin thread bobbin, the defective bobbin, and the lead bobbin are drawn out from the tray T, the bobbin processing controller 11 controls the bobbin mounting device 43 to mount the yarn feeding bobbin Bs on the empty tray T (S217, S218, and S219, respectively). Thus, the defective bobbin can be drawn out from the tray T until the yarn feeding bobbin Bs is attached to the tray T without depending on the manual work. Further, both the defective bobbin and the empty bobbin can be drawn out by the bobbin drawing device 42. Therefore, the manufacturing cost can be reduced compared to a structure in which the bobbin B is separately drawn out.

(4) In the embodiments described above, the first sorting path 76 and the second sorting path 77 are formed so as to extend at least downward as they go downstream in the moving direction of the drawn-out bobbin Bp, but the present invention is not limited thereto. For example, the first sorting path 76 and the second sorting path 77 may extend in the horizontal direction, and the drawn-out bobbins Bp on these paths may be conveyed by a conveying mechanism or the like.

(5) In the embodiments described above, the discharge boxes are provided corresponding to the sorting paths 75, but the present invention is not limited to this. For example, each sorting path 75 may be configured such that the operator can access the drawn-out bobbin Bp and the drawn-out bobbin Bp is processed one by the operator.

(6) In the embodiments described above, the RF tag 100 of the tray T is formed to record the quality information or the count information, but the invention is not limited thereto. For example, the winding unit 7 may be configured to be able to attach a label to which a barcode indicating that the bobbin B is a defective bobbin to the tray T or the bobbin B. In this case, the bobbin B also corresponds to the quality information imparting unit of the present invention. Alternatively, identification information may be given to all of the bobbins B by a barcode or the like in advance, and the winding unit 7 may be configured to transmit the identification information read from the barcode to the machine body control device 5 in association with the quality information or the count information. The machine body control device 5 may be configured to be capable of storing the quality information or the count information in association with the identification information of the tray T. In this case, the body control device 5 corresponds to the quality information imparting unit and the frequency information imparting unit of the present invention.

(7) In the embodiments described above, the dispensing bobbins Bp are sorted by the sorting path 75 and the switching mechanism 72, but the present invention is not limited thereto. For example, the bobbin sorting device 45 may be configured to attach a label or the like indicating that the drawn bobbin Bp is a defective bobbin to the drawn bobbin Bp. In this case, the bobbin sorting device 45 may discharge all the drawn bobbins Bp to 1 discharge box, and then the operator may visually sort the bobbins.

(8) In the embodiments described above, the bobbin processing control section 11 is configured to remove the bobbin B other than the defective bobbin from the tray T by the bobbin extracting device 42, but the present invention is not limited thereto. For example, the bobbin processing device 3 may include a package yarn removing device capable of removing a small amount of package yarn from a small amount of package yarn bobbins (see japanese patent application laid-open No. 2016 and 102004). The bobbin for the lead wire may be wound around the winding path 37 until the lead wire processing is successful. In such a case, a small number of bobbin thread bobbins or bobbin for lead thread are not necessarily drawn out from the tray T by the bobbin drawing device 42. That is, the bobbin processing control unit 11 may draw out only the defective bobbin from the tray T by the bobbin drawing device 42. In this case, the bobbin sorting device 45 is not necessarily provided.

(9) In the embodiments described above, the yarn clearer 22 formed as the winding unit 7 monitors the yarn Y and determines the quality of the yarn feeding bobbin Bs, but the present invention is not limited thereto. The monitoring unit and the determining unit may be provided separately. For example, the yarn clearer 22 may transmit the monitoring result of the yarn Y to the unit control unit 12, and the unit control unit 12 may determine the quality of the yarn feeding bobbin Bs. In this case, the clearer 22 functions only as a monitoring unit of the present invention. The cell control unit 12 functions as a determination unit of the present invention. That is, the determination unit of the present invention may be included in the unit control unit 12. Thus, even if the clearer 22 is not configured to function as the determination unit of the present invention, the unit control unit 12 can determine whether or not the yarn feeding bobbin Bs is a defective bobbin.

(10) In the embodiments described above, the bobbin processing control unit 11 controls the respective parts of the bobbin processing device 3, but the present invention is not limited to this. For example, the body control device 5 may control each part of the bobbin processing device 3. In this case, the body control device 5 corresponds to the bobbin process control unit of the present invention.
