Next, a first embodiment of the present invention will be described with reference to the drawings. First, the automatic winder system 1 will be described with reference to FIG. The automatic winder system 1 shown in FIG. 1 includes two bobbin supply devices 2, a bobbin preparation device 3, and an automatic winder (yarn winding device) 8. The two bobbin supply devices 2 have the same configuration.

The bobbin supply device 2 is loaded with yarn feeding bobbins collectively. The yarn feeding bobbin is obtained by winding a spun yarn generated in a spinning machine in the previous process around a bobbin tube. The bobbin supply device 2 separates the yarn feeding bobbins that have been put together, and puts them on a transport tray and supplies them to the bobbin preparation device 3. The detailed configuration of the bobbin supply device 2 will be described later.

The bobbin preparation device 3 includes a yarn end processing device 4, an outlet device 5, a supply path 6, and a recovery path 7. The yarn end processing device 4 performs a process of forming a yarn end on the yarn supplying bobbin supplied from the bobbin supply device 2. The lead-out device 5 performs a lead-out process of inserting the yarn end formed by the yarn end processing device 4 into the bobbin tube. The supply path 6 conveys the yarn feeding bobbin placed on the conveyance tray to the automatic winder 8. The collection path 7 conveys the yarn feeding bobbin, in which all yarns have been unwound by the automatic winder 8, from the automatic winder 8 to the bobbin supply device 2. The bobbin supply device 2 collects the yarn feeding bobbin from which all the yarns have been unwound.

The automatic winder 8 includes a plurality of winding units 9. Each winding unit 9 unwinds the yarn from the yarn supplying bobbin and winds it on the winding bobbin to form a package.

Next, with reference to FIG.2 and FIG.3, the detailed structure of the bobbin supply apparatus 2 is demonstrated. As shown in FIGS. 2 and 3, the bobbin supply device 2 according to the present embodiment includes a bobbin input unit 22, a bobbin extraction unit 23, and a supply unit 24. The supply unit 24 includes a direction adjustment unit 27, a bunch removal unit 28, and a bobbin placement unit 29.

The yarn feeding bobbin 10 that has been carried in the container 11 is loaded into the staying portion 22 a of the bobbin loading portion 22. The bobbin group thrown into the bobbin throwing-in part 22 is picked up one by one by the bobbin taking-out part 23 and individualized.

The bobbin insertion portion 22 includes a swing member 41 configured to be swingable. The swinging member 41 swings at a predetermined angular stroke, so that the bobbin group thrown into the bobbin throwing part 22 is blocked or broken, and the yarn feeding bobbin 10 is fed to the bobbin take-out part 23 by a substantially constant amount. Can be supplied. Thereby, since it is possible to prevent a large amount of yarn supplying bobbins 10 from being supplied to the bobbin extracting portion 23 at a time, the bobbins extracting portion 23 can reliably take up the yarn supplying bobbins 10 one by one.

In addition, the bobbin loading unit 22 includes a cutter 43. The cutter 43 is configured in a scissors shape, and is configured to be able to cut the yarn output from the yarn supplying bobbin 10 by being driven by a drive source (not shown). Even when the yarn feed bobbin 10 is transported from the bobbin loading portion 22 to the bobbin take-out portion 23, the cutter 43 is not affected by the yarn feeding bobbin 10 (when there is yarn drawing). Can be cut off. Thereby, even if the yarn feeding bobbin 10 is stirred by the bobbin tray 26 when it is picked up by the bobbin take-out portion 23, occurrence of yarn entanglement can be prevented and individualization can be performed appropriately.

The bobbin take-out part 23 is configured as a conveyor arranged in the vertical direction. Specifically, the bobbin take-out portion 23 includes an endless annular band 25 and a plurality of bobbin dishes 26 attached at equal intervals in the longitudinal direction of the endless annular band 25 on the outer surface of the endless annular band 25. It is equipped with.

The endless annular band 25 is configured as a band-shaped (sheet-shaped) member that is looped between two rotating rollers (not shown) arranged above and below. Thus, by driving one of the rotating rollers, the endless annular band 25 is circulated and driven, and the bobbin tray 26 attached to the endless annular band 25 is driven in the vertical direction.

Moreover, by setting it as the structure which attaches the bobbin dish 26 to the endless annular strip 25, the bobbin dish 26 can be supported stably compared with the structure which attaches a bobbin dish to an endless chain, for example. Further, since the back side of the bobbin tray 26 is closed by the sheet-like endless annular band 25, the bobbin on the bobbin tray 26 does not fall to the back side of the apparatus. .

The bobbin tray 26 has a rectangular surface as a whole so that the yarn feeding bobbin 10 can be placed thereon. The depth of the bobbin tray 26 (the length in the front and back direction in FIG. 2) is such a length that two yarn feeding bobbins 10 cannot be laid side by side. With this configuration, the endless annular belt 25 is driven to circulate, so that the yarn feeding bobbins 10 in the bobbin feeding section 22 are placed one by one on the bobbin tray 26 and conveyed upward in the vertical direction with respect to the apparatus installation surface. It is supposed to be. In this way, the bobbin groups in the bobbin inserting section 22 can be taken up (individualized) one by one.

The yarn feeding bobbin 10 conveyed upward by the bobbin take-out unit 23 is temporarily stocked by the stock unit 44. An open / close door 45 is installed in the vicinity of the stock portion 44 (see FIG. 3). By opening the opening / closing door 45, the yarn entanglement of the yarn feeding bobbin 10 stocked in the stock portion 44 can be removed. The yarn feeding bobbin 10 stocked in the stock unit 44 is sent to the direction adjusting unit 27 at a predetermined timing.

The direction adjustment unit 27 includes a pressing unit 46 and a processing unit 47. The pressing unit 46 presses the yarn feeding bobbin 10 sent from the stock unit 44 from the rear side to the front side in FIG. The processing unit 47 determines the unwinding side end and the support side end of the received yarn feeding bobbin 10, and adjusts the direction of the yarn feeding bobbin 10 so that the unwinding side end is downward, It is dropped on the lower bunch removing unit 28.

The bunch removing unit 28 includes a housing 81, a rotary feeder 82, a drive motor 83, and a suction mechanism 84 as main components.

The housing 81 rotatably supports the rotary feeder 82 and includes a direction changing plate 85. The direction changing plate 85 is configured as a flat plate-like member directed obliquely. The direction changing plate 85 changes the direction of the yarn supplying bobbin 10 by approximately 90 ° and guides the direction of the yarn supplying bobbin 10 so that the unwinding side end portion faces the side far from the direction changing plate 85.

The rotary feeder 82 is configured by combining plate-like partitions, and a bobbin housing space partitioned into six spaces is configured by the partitions. Each bobbin space is formed in an elongated shape, and is arranged so that its longitudinal direction is parallel to the axis of the rotary feed body 82.

The drive motor 83 is a motor for driving the rotary feeder 82. By driving the drive motor 83, the rotary feeder 82 can be rotated to feed the yarn feeding bobbin 10 downward.

The suction mechanism 84 includes a cylinder that can move in a direction along the longitudinal direction of the bobbin housing space, and can generate a suction flow from the cylinder. Thereby, the bunch winding wound around the support side of the yarn feeding bobbin 10 is sucked, so that the bunch winding can be removed. The number of operations of the suction mechanism 84, the operation time, and the timing for removing the suctioned bunch (the operation timing of the cutter) can be changed by a setting unit provided in the automatic winder system 1. Thereby, the optimum bunch removal according to the yarn type and the bunch winding state can be performed.

After removing the bunch winding of the yarn supplying bobbin 10, the bobbin supplying device 2 drives the rotary feeder 82 to send the yarn supplying bobbin 10 to the discharge position, and drops it via the bobbin placing portion 29. Under the bobbin placement unit 29, the transport tray 21 stands by, and the yarn feeding bobbin 10 from the bobbin placement unit 29 is placed on the transport tray 21.

The bobbin supply device 2 includes a bobbin extraction device 30. In the drawing, the bobbin extraction device 30 is drawn with a chain line in consideration of the visibility of the bobbin extraction portion 23 and the like. The bobbin extracting device 30 is a device that extracts the bobbin tube of the yarn feeding bobbin 10 placed on the transport tray 21 transported by the collection path 7. The bobbin extraction device 30 includes a frame 31, a belt 32, a movable member 33, a pulley 34, and a bobbin chute 35.

The frame 31 is disposed below the bobbin extraction device 30. A belt 32 is attached to the frame 31. The movable member 33 is disposed so as to face the frame 31 and is movable in a direction approaching the frame 31 by a driving force of a driving unit (not shown). A pulley 34 is attached to the movable member 33. With this configuration, the bobbin tube of the yarn supplying bobbin 10 can be pulled out by driving the pulley 34 in a state where the movable member 33 is brought close to the frame 31 and the yarn supplying bobbin 10 is sandwiched between the belt 32 and the pulley 34.

The bobbin tube of the yarn feeding bobbin 10 thus extracted is put into the bobbin accommodation device 36 by the bobbin chute 35. In order to accommodate the bobbin tube of the yarn feeding bobbin 10 evenly in the bobbin accommodating device 36, the bobbin chute 35 is provided with a branching portion 35a, and the position where the bobbin tube of the yarn feeding bobbin 10 is inserted is set. It can be switched appropriately.

Next, with reference to FIGS. 3 to 6, a configuration for notifying an operator when a problem occurs will be described.

The bobbin supply device 2 includes an upper lamp 51, a device display unit 52, and a failure display unit (notification unit) 53 as a configuration for reporting a failure (see FIG. 3). Further, the upper lamp 51 and the failure display unit 53 are controlled by the control unit 60 (see FIG. 4).

The upper lamp 51 is a rod-shaped lamp attached to the upper surface of the bobbin extraction part 23. The upper lamp 51 emits light when a malfunction occurs. The upper lamp 51 can change the emission color according to the malfunction that has occurred.

As shown in FIG. 5, the device display unit 52 is a diagram schematically showing the entire bobbin supply device 2. The device display unit 52 is a seal member and is attached to the side surface of the bobbin extraction unit 23. The device display unit 52 is printed with a graphic indicating a component of the bobbin supply device 2 and identification information of the component. In FIG. 5, identification information from p1 to p8 is displayed. “P1” indicates the staying part 22a, “p2” indicates the bobbin take-out part 23, “p3” indicates the control part 60, “p4” and “p5” indicate the pressing part 46, and “p6” indicates the stock. 4, “p 7” indicates the direction adjustment unit 27, and “p 8” indicates the bunch removal unit 28. “D8” indicates the bobbin chute 35.

The automatic winder system 1 includes two bobbin supply devices 2. One bobbin supply device 2 uses identification information “o1” to “o8”, and the other bobbin supply device 2 uses “p1” to “p8”. Is used. Thereby, even if it is a case where identification information is displayed on the control apparatus which controls the whole automatic winder system 1, confusion can be prevented.

In the present embodiment, the device display unit 52 is a perspective view, but may be a side view. The device display unit 52 may have any display mode as long as the entire bobbin supply device 2 is displayed. The display content may be a mode in which the display content does not change as in the present embodiment. May be a mode in which can be changed. Further, the method of attaching the identification information is arbitrary, and the identification information may be given more roughly than in FIG. 5, or the identification information may be given in more detail than in FIG. For example, identification information may be further added to a portion where the bobbin extracting device 30 extracts the bobbin tube of the yarn supplying bobbin 10 or a portion where the extracted yarn supplying bobbin 10 is conveyed to the bobbin chute 35.

The defect display unit 53 is a display capable of displaying at least identification information, and is disposed on the side surface of the bobbin extraction unit 23. The defect display unit 53 can display identification information according to an instruction from the control unit 60. For example, when a failure occurs in the staying portion 22a, the control unit 60 causes the failure display portion 53 to display “p1” that is identification information corresponding to the staying portion 22a.

As a result, the operator can identify the location where the failure has occurred simply by checking the device display unit 52 and the failure display unit 53. In particular, in the present embodiment, since the device display unit 52 and the defect display unit 53 are arranged close to each other, the occurrence location of the defect can be identified at a glance.

Next, problems detected by the bobbin supply device 2 will be listed and a method for detecting the problems will be briefly described.

The first problem is that the yarn supplying bobbin 10 is present in the staying part 22a, but the yarn supplying bobbin 10 is not supplied to the bobbin take-out part 23 due to clogging of the yarn supplying bobbin 10 or the like. The bobbin supply device 2 detects the presence / absence of the staying portion bobbin detection sensor 61 for detecting the presence / absence of the yarn feeding bobbin 10 in the staying portion 22a and the presence / absence of the yarn feeding bobbin 10 at the entrance of the bobbin takeout portion 23 in order to detect this problem. And a conveyor entrance bobbin detection sensor 62 for detection (see FIGS. 2 to 4). The staying part bobbin detection sensor 61 and the conveyor entrance bobbin detection sensor 62 are, for example, optical sensors, and detect the presence or absence of the yarn feeding bobbin 10 based on whether or not the light emitted from the light projecting part is blocked. When the staying portion bobbin detection sensor 61 detects the yarn feeding bobbin 10 but the conveyor entrance bobbin detection sensor 62 does not detect the yarn feeding bobbin 10 continues for a predetermined time, the control unit 60 displays the failure display unit 53. "P1" is displayed on the upper lamp 51 and the upper lamp 51 is lit red (see FIG. 6A).

The second problem is a problem that the endless annular band 25 does not move due to the yarn feeding bobbin 10 being caught by the bobbin take-out portion 23. The bobbin supply device 2 includes a conveyor conveyance detection sensor 63 that detects the presence or absence of movement of the bobbin tray 26 (endless annular band 25) in order to detect this problem. The conveyor conveyance detection sensor 63 is, for example, an optical sensor, and detects whether or not the bobbin tray 26 has moved based on whether or not the light emitted from the light projecting unit is periodically blocked (by the bobbin tray 26). To do. If it is detected by the conveyor conveyance detection sensor 63 that the bobbin tray 26 has not moved, and clogging is not eliminated even when the endless annular band 25 is rotated in reverse, the control unit 60 does not move. Then, “p2” is displayed on the defect display portion 53 and the upper lamp 51 is lit red.

The third problem is a problem in which the yarn supply bobbin 10 does not reach the stock part 44 or the yarn supply bobbin 10 is not conveyed downstream from the stock part 44 because the yarn of the yarn supply bobbin 10 is caught. The bobbin supply device 2 detects whether or not the yarn feeding bobbin 10 is set in the stock portion bobbin detection sensor 64 for detecting the presence or absence of the yarn feeding bobbin 10 in the stock portion 44 and the pressing portion 46 in order to detect this problem. And a pressing part bobbin detection sensor 65 for detecting this. The stock part bobbin detection sensor 64 and the pressing part bobbin detection sensor 65 are, for example, optical sensors, and detect the presence or absence of the yarn feeding bobbin 10 based on whether or not the light emitted from the light projecting unit is blocked. If the control unit 60 does not detect the yarn feeding bobbin 10 even if the stock unit bobbin detection sensor 64 or the pressing unit bobbin detection sensor 65 detects the yarn feeding bobbin 10 even though the yarn feeding bobbin 10 is cut, the control unit 60 “P6” is displayed on the defect display portion 53 and the upper lamp 51 is lit red.

A fourth problem is a problem that the yarn feeding bobbin 10 is not conveyed by the bobbin take-out unit 23. When the conveyor entrance bobbin detection sensor 62 detects the yarn feeding bobbin 10 but the stock portion bobbin detection sensor 64 does not detect the yarn feeding bobbin 10 continues for a predetermined time, the control unit 60 displays a defect display unit. “P1” is displayed in 53 and the upper lamp 51 is lit red.

The fifth problem is a problem in which the conveyance from the stock unit 44 to the pressing unit 46 has failed. When the pressing unit bobbin detection sensor 65 does not detect the yarn feeding bobbin 10 even though the stock unit 44 has sent the yarn feeding bobbin 10 downstream, the control unit 60 displays “p5” on the defect display unit 53. At the same time, the upper lamp 51 is lit red.

A sixth problem is a problem in which the yarn feeding bobbin 10 is conveyed in a state where the opening / closing door 45 is opened. In order to detect this problem, the bobbin supply device 2 uses the stock portion bobbin detection sensor 64 as a reflective optical sensor, and has a reflector on the back side of the open / close door 45. Therefore, while the open / close door 45 is open, the reflected light cannot be detected as in the case where the yarn feeding bobbin 10 is in the stock portion 44. When the stock section bobbin detection sensor 64 does not detect reflected light continuously for a predetermined time, the control section 60 determines that the opening / closing door 45 is open or the yarn feeding bobbin 10 is clogged, and the malfunction display section 53 "P6" is displayed on the top and the upper lamp 51 is lit red.

The seventh problem is a problem that the yarn feeding bobbin 10 is not properly set in the pressing portion 46. The bobbin supply device 2 is provided with two pressing portion bobbin detection sensors 65 to detect this problem, and detects two locations of the yarn feeding bobbin 10. If only one of the pressing portion bobbin detection sensors 65 detects the yarn feeding bobbin 10, and the state does not change even if air is blown out and the fluff is removed, the control unit 60 displays a failure display unit. “P4” is displayed in 53 and the upper lamp 51 is lit red.

The eighth problem is a problem that the conveyance from the direction adjusting unit 27 to the bunch removing unit 28 has failed. When the bunch removing unit 28 does not detect the yarn feeding bobbin 10 even though the pressing unit 46 and the processing unit 47 are operated a plurality of times, the control unit 60 displays “p4” on the defect display unit 53 and the upper part. The lamp 51 is lit red.

The ninth problem is a problem that the origin return operation of the rotary feed member 82 of the bunch removing unit 28 has failed. The bobbin supply device 2 includes an origin sensor 66 for adjusting the origin of the rotary feeder 82 and the like. The origin sensor 66 is a sensor that detects the magnetic force of a magnet attached to each bobbin accommodating space of the rotary feeder 82, for example. When the origin sensor 66 detects a predetermined magnetic force, it is determined that the rotary feeder 82 is at the origin. If the rotary feeder 82 does not return to the origin even when the rotary feeder 82 is returned to the origin based on the detection value of the origin sensor 66, the control unit 60 displays “p8” on the failure display unit 53. At the same time, the upper lamp 51 is lit red.

The tenth defect is a defect in which clogging occurs in the bunch removing unit 28. When the bobbin placement unit 29 does not place the yarn feeding bobbin 10 on the transport tray 21 even when the bunch removal unit 28 operates, the control unit 60 displays “p8” on the failure display unit 53 and turns the upper lamp 51 on. Turn on red.

The eleventh defect is a defect in which the bobbin chute 35 of the bobbin extraction device 30 is clogged with the yarn feeding bobbin 10. The bobbin supply device 2 includes a bobbin chute bobbin detection sensor 67 that detects the yarn feeding bobbin 10 in the upstream portion of the bobbin chute 35 in order to detect this problem. The bobbin chute bobbin detection sensor 67 is, for example, an optical sensor, and detects the presence or absence of the yarn feeding bobbin 10 based on whether or not the light emitted from the light projecting unit is blocked. When the bobbin chute bobbin detection sensor 67 continues to detect the yarn feeding bobbin 10 for a predetermined time or more and the state does not change even when the branching portion 35a is operated, the control unit 60 displays “d8 "And the upper lamp 51 is lit red.

The twelfth to fourteenth problems are not such problems that the process is interrupted, but are minor problems that alert the operator. The defect in this specification includes a serious defect and a minor defect. When this minor malfunction occurs, the control unit 60 lights the upper lamp 51 in yellow.

The twelfth problem is a problem that indicates that the bobbin tube of the yarn feeding bobbin 10 of a predetermined value or more is accommodated in the bobbin accommodation device 36 and the capacity is exceeded soon. When the twelfth failure occurs, the control unit 60 displays “bF” indicating “bobbin full” on the failure display unit 53. The thirteenth problem is a problem that the yarn supplying bobbin 10 is not provided in the bobbin feeding portion 22 and the yarn supplying bobbin 10 cannot be supplied in the near future. The fourteenth defect is a defect in which a predetermined time has elapsed since the yarn feeding bobbin 10 has disappeared in the bobbin take-out portion 23 after the thirteenth defect. When the thirteenth and fourteenth defects occur, the control unit 60 displays “bE” indicating “bobbin empty” on the defect display unit 53 (see FIG. 6B).

As described above, the bobbin supply device 2 of the first embodiment includes the bobbin insertion unit 22, the bobbin extraction unit 23, the supply unit 24, and the failure display unit 53. The bobbin loading unit 22 is loaded with a plurality of yarn feeding bobbins 10 around which yarn spun by the spinning device is wound. The bobbin take-out unit 23 individually takes out the yarn feeding bobbin 10 from the bobbin group put into the bobbin input unit 22. The supply unit 24 supplies the yarn feeding bobbin 10 taken out by the bobbin take-out unit 23 to the bobbin preparation device 3 individually. The malfunction display unit 53 notifies the location of the malfunction when a malfunction occurs in the operation from when the yarn feeding bobbin 10 is turned on to when it is supplied.

Thereby, in the bobbin supply device, it is possible to notify the occurrence location of the malfunction. Therefore, when a problem occurs, it can be quickly repaired, so that manufacturing efficiency can be improved.

Further, the bobbin supply device 2 of the first embodiment includes a device display unit 52. In the device display section 52, identification information is shown for each component of the bobbin supply device 2. The defect display unit 53 notifies the occurrence location of the defect by displaying the identification information of the component part.

This eliminates the need for an electrical configuration in the device display unit, thereby reducing costs. Moreover, since the operator can specify the location where the failure occurs only by looking at the failure display unit 53 when a failure occurs, the operator can quickly identify the failure.

Next, a first modification of the above embodiment will be described with reference to FIG. In the following description, the same or similar members as those of the above-described embodiment are denoted by the same reference numerals in the drawings, and the description may be omitted.

In the above embodiment, the display of the device display unit 52 does not change. On the other hand, in the device display unit 52x of the first modification, a plurality of light sources (notification units) are arranged on the back side of the seal member. Each light source can individually illuminate the constituent parts of the device display unit 52. When the control unit 60 detects that a failure has occurred, the control unit 60 illuminates a component of the device display unit 52x corresponding to the location where the failure has occurred. FIG. 7 shows an example in which the control unit 60 causes the portion corresponding to the staying part 22a of the device display unit 52 to shine.

Thereby, it is possible to more intuitively and easily grasp the location where the defect occurs. Note that the device display unit 52x is not limited to a configuration in which a failure occurrence location is notified by whether or not lighting is present, but may be configured to notify a failure occurrence location by a lighting color or blinking.

Next, a second modification of the above embodiment will be described with reference to FIG.

As illustrated in FIG. 8, the bobbin supply device 2 x of the second modification includes a plurality of light sources (notification units) 90. The light source 90 is disposed for each component of the bobbin supply device 2. When the control unit 60 detects that a failure has occurred, the control unit 60 causes the light source 90 arranged in the component corresponding to the occurrence location of the failure to shine.

As a result, the location where the failure occurs is the same as the portion that reports the failure. For example, if the location where the failure has occurred can be estimated, it can be confirmed that the failure has occurred at the occurrence location, and at the same time, the failure can be dealt with. .

Note that the first embodiment and the first and second modifications may be used in combination. For example, it is possible to turn on the light source 90 arranged at the failure occurrence location while notifying the occurrence location of the failure on the failure display unit 53 or the device display unit 52x.

Next, a second embodiment will be described with reference to FIG.

Although 1st Embodiment is the structure which alert | reports the occurrence location of the malfunction of the bobbin supply apparatus 2, 2nd Embodiment is a structure which alert | reports the occurrence location of the malfunction of the bobbin preparation apparatus 3. FIG. Even when the occurrence location of the malfunction of the bobbin preparation device 3 is notified, the configuration of the first embodiment, the first modified example, or the second modified example can be employed. Here, the bobbin preparation device 3x adopting the configuration of the second modification will be described.

As shown in FIG. 9, the bobbin preparation device 3 x includes a plurality of light sources (notification units) 91. The light source 91 is disposed for each component of the bobbin preparation device 3. A plurality of light sources 91 are arranged at portions corresponding to the yarn end processing device 4 and the spouting device 5, and a plurality of light sources 91 are arranged in the supply path 6 and the recovery path 7 for each predetermined distance. The control part 60 makes the light source 91 arrange | positioned in the component corresponding to the location where a malfunction generate | occur | produces light.

Here, when the occurrence location of the defect of the bobbin preparation device 3x is displayed on the display unit, the operator needs to move to the display unit and check the occurrence location of the failure every time a failure occurs. Since the bobbin preparation device 3 is large in size, it is troublesome for the operator. In this regard, in the second embodiment, the location where the failure has occurred and the portion that reports the same are the same. For example, when the location where the failure has occurred can be estimated, it is confirmed that the failure has occurred at the location where the failure has occurred. You can take action.

The preferred embodiments and modifications of the present invention have been described above, but the above configuration can be modified as follows, for example.

In the above description, the automatic winder system 1 in which two bobbin supply devices 2 are arranged has been described. However, the number may be one, or may be three or more.

The problem and the detection method described above are examples, and a problem other than the above may be detected and notified.

The attachment position of the device display unit 52 is not limited to the bobbin take-out unit 23, and may be a side surface of the bobbin insertion unit 22 or the supply unit 24, for example. Alternatively, a plurality of device display units 52 may be pasted.

In the above description, a plurality of examples of notifying the occurrence location of the failure of the bobbin supply device 2 and the bobbin preparation device 3 have been described. However, the occurrence location of the failure may be notified by other methods (for example, voice or the like).

The present invention can also be configured as follows.

If the bunch removal unit 28 is ready to be received at the start of operation, the direction adjustment is performed based on the latest direction determination result stored in the storage unit 60 provided in the control unit regardless of the presence or absence of the bobbin in the direction adjustment unit 27. The direction adjustment operation by the unit 27 is executed. Thereafter, if the presence of the bobbin is detected in the bunch removing unit 28, the automatic operation is started. If the bobbin is not detected, the direction adjusting unit 27 is driven again and then the automatic operation is started. By operating in this way, it is possible to perform an operation start operation that generates as little bobbin clogging as possible in the direction adjustment unit 27 at the start of operation. The above-described operation can be omitted by providing a dedicated sensor in the direction adjustment unit 27 and confirming the presence of the bobbin remaining in the direction adjustment unit 27.

Further, it is preferable to intermittently drive the endless annular band 25 (conveyor) disposed in the vertical direction on the bobbin take-out portion 23 at the start of operation. By intermittently driving at the start of operation, the yarn supplying bobbin 10 can be prevented from being continuously supplied from the bobbin take-out unit 23 toward the yarn supplying bobbin 10 remaining in the stock unit 44. By operating in this way, it is possible to start without causing as much as possible the clogging of the bobbin in the stock section 44 at the start of operation. Moreover, the above-mentioned operation | movement can also be abbreviate | omitted by making a bobbin extraction part 23 confirm the presence of a bobbin by providing a dedicated sensor in the upper end part of the conveyor arrange | positioned by the up-down direction.

The swing member 41 is driven when the conveyor entrance bobbin detection sensor 62 detects that there is no more bobbin to be taken out below the bobbin take-out portion 23 (when the conveyor entrance bobbin detection sensor 62 stops detecting the bobbin). You may comprise. With this configuration, the number of bobbins supplied to the conveyor portion of the bobbin take-out unit 23 can be kept below a certain level, so that troubles in conveyor operation due to excessive loading of bobbins into the conveyor can be avoided. it can. As a malfunction of the conveyor, there is a bridge state that occurs when an excessively loaded bobbin enters irregularly and is disturbed. In the bridge state, a bobbin take-out error by the conveyor occurs.

Further, when the swing member 41 is operated, it may not swing to a predetermined position. In such a case, the bobbin is often caught by the movable part of the swing member 41. Therefore, when the swinging member 41 does not swing to the predetermined position, the operation for swinging once in the reverse direction (returning) and swinging to the predetermined position is executed again. By operating in this way, the bobbin caught on the movable part of the swinging member 41 may be removed, and the trouble solving work by the operator can be omitted.

  Further, the cutter 43 provided in the bobbin inserting portion 22 is provided at one end portion of the swing member 41. More specifically, the swing member 41 is provided on the downstream side in the direction in which the yarn feeding bobbin 10 is conveyed from the bobbin loading portion 22 to the bobbin taking-out portion 23. Therefore, it is desirable to operate the cutter 43 in a state of swinging so that the one end side of the swinging member 41 rises upward (the state of the two-dot chain line in FIG. 2). By operating the cutter in this way, the yarn drawn from the yarn feeding bobbin 10 conveyed from the bobbin loading unit 22 to the bobbin taking-out unit 23 is guided to the cutter 43 with high probability, and the drawn yarn is efficiently cut. be able to. Thereby, generation | occurrence | production of malfunctions, such as a tangle of a thread | yarn, can be prevented and a bobbin can be individualized appropriately.

  Further, a sensor for detecting the yarn feeding bobbin 10 taken out by the bobbin tray 26 attached to the endless annular band 25 provided in the bobbin take-out portion 23 may be provided within the movable range of the endless annular band 25. Thus, by detecting the yarn feeding bobbin 10 taken out to the bobbin tray 26, it is possible to grasp the number of bobbins actually taken out. Further, since the number of yarn feeding bobbins 10 carried from the bobbin tray 26 to the stock unit 44 can be detected by the stock unit bobbin detection sensor 64, the number of yarn feeding bobbins 10 taken out to the bobbin tray 26. By subtracting the number of yarn feeding bobbins 10 carried from the stock unit 44 to the stock section 44, the number of yarn feeding bobbins 10 placed on the bobbin tray 26 at that time can be grasped. By strictly managing the number of bobbins in this way, it becomes possible to immediately find defects such as bobbin clogging.

  Further, as described above, the number of yarn feeding bobbins 10 placed on the bobbin tray 26 is grasped, and when the yarn feeding bobbin 10 exists on the bobbin tray 26, the endless annular band 25 is operated at a high speed. Let Conversely, when the yarn feeding bobbin 10 is not present on the bobbin tray 26, the bobbin tray 26 is operated at a low speed. Further, when the endless annular band 25 is stopped, the cutter 43 is also stopped. As a result, energy saving can be realized, and consumption of the cutter 43 can be suppressed.

  When the endless annular band 25 is stopped when the yarn feeding bobbin 10 is present on the bobbin tray 26, the endless annular band 25 is held by a drive source (for example, a stepping motor) that drives the endless annular band 25. It is preferable to pass a holding current for the purpose. If the current of the stepping motor is turned off when the yarn feeding bobbin 10 is present on the bobbin tray 26, the endless annular band 25 can be prevented from rotating due to the weight of the yarn feeding bobbin 10. . As a result, the yarn feeding bobbin 10 on the bobbin tray 26 can be prevented from falling, and the calculated number of yarn feeding bobbins 10 and the number of yarn feeding bobbins 10 actually present on the bobbin tray 26 are obtained. It is possible to prevent the difference.

  The unwinding side end and the support side end of the yarn feeding bobbin 10 received by the processing unit 47 are discriminated. However, by providing four sensors, the unwinding side end and the support side end of the yarn feeding bobbin 10 are provided. In addition to the part determination, the length of the yarn feeding bobbin 10 may be determined. The yarn feeding bobbins 10 having different lengths may be discharged to another path, or the processing may be continued as long as the length is within an allowable range. Thereby, even when the yarn feeding bobbins 10 having different lengths are mixed, the process can be automatically executed.

  Moreover, the sensor for detecting the rotational position of the direction change board 85 for the process part 47 of the direction adjustment part 27 to change the direction of the yarn feeding bobbin 10 can be provided. By providing the sensor in this manner, the direction change plate 85 can be returned to the initial position when the position of the direction change plate 85 is deviated from the specified initial position at the start of operation. Since there is a possibility that the yarn feeding bobbin 10 remains on the direction change plate 85 at the start of operation, it is preferable that the initial position movement of the direction change plate 85 is executed at a low speed at the start of operation. In addition, by providing a sensor for detecting the rotational position on the direction change plate 85 as described above, even when the position is shifted during operation, the occurrence of a malfunction and the position adjustment (initial position return) are performed. Is possible. Further, the speed of the initial position return may be accelerated stepwise or linearly in proportion. By accelerating in this way, adverse effects due to inertia at the time of starting the motor can be prevented. For example, when a stepping motor is employed as the drive source, the stepping motor can be prevented from stepping out.

  In addition, the bobbin pulling device 30 is disposed on the upstream side of the portion (position) where the bobbin tube of the yarn supplying bobbin 10 is extracted, and the yarn wound around the yarn supplying bobbin 10 placed on the conveying tray to be conveyed. Two types of sensors for detecting the amount (remaining yarn amount) are arranged. The two types of sensors are contact-type sensors that detect the presence or absence of yarn by contacting the yarn layer. As a first sensor, a brush type sensor that moves the brush member in the vertical direction to detect the presence or absence of a thread is disposed. The brush type sensor detects the presence or absence of the yarn on the yarn feeding bobbin that is the detection target. When the yarn is not detected by the brush type sensor, it is determined that the yarn supplying bobbin is a bobbin on which no yarn is wound, that is, an empty bobbin. A feeler type sensor that detects the thickness of the yarn layer (the amount of yarn) by bringing a movable contact bar into contact with the yarn feeding bobbin is disposed as a second sensor. The combination of these brush type sensor and feeler type sensor can detect the presence / absence of yarn and the amount of yarn. Either of these two types of sensors may be arranged on the upstream side, but if the target bobbin is an empty bobbin by arranging the brush type sensor on the upstream side, the determination of the empty bobbin is performed only by the detection of the brush type sensor. Therefore, the detection operation of the feeler type sensor can be omitted. Further, by detecting twice, a malfunction in the upstream sensor, for example, a detection error caused by wear due to brush wear can be detected by the second detection, and an alarm can be notified. As the alarm, lamp lighting, a hop-up display on the operation screen provided in the machine control unit of the automatic winder, etc. are adopted.

  When it is confirmed by the brush type sensor that the yarn remains, the amount of the yarn is detected by the feeler type sensor. When it is confirmed by the feeler type sensor that the amount of yarn that can be operated by the automatic winder remains (there is a remaining yarn amount greater than a certain value), the bobbin tube is pulled out from the yarn supply bobbin to be detected The portion (position) is not processed, but is conveyed to the downstream outlet device 5 as it is, and the outlet processing is executed in the same manner as the yarn supplying bobbin (full-winding yarn supplying bobbin) in which other yarns are sufficiently wound. On the other hand, if it is confirmed by the feeler type sensor that the amount of yarn that can be operated with an automatic winder does not remain (yarn remains, but there is no remaining yarn amount greater than a certain value), The yarn feeding bobbin is pulled out at the portion (position) where the bobbin tube is pulled out and is collected in a bobbin collecting box with a residual yarn provided in the bobbin supplying device 2.

The bobbin recovery box with residual yarn is provided with a sensor that detects that the yarn supply bobbin with residual yarn that has been pulled out and collected is full. If the bobbin overflows from the bobbin recovery box with remaining thread,
The overflow of the yarn feeding bobbin that overflows may cause damage to members disposed below the bobbin collection box with residual yarn and damming of the conveyance path. The bobbin recovery box with the remaining yarn is provided with a sensor for detecting that the remaining yarn supplying bobbin with the remaining yarn extracted and recovered by the bobbin extracting device 30 is full. It is possible to detect and deal with the possibility of overflowing in advance. For example, when the yarn supplying bobbin with remaining yarn detects that the bobbin collecting box with remaining yarn is full, the control unit 60 stops the bobbin extraction operation by the bobbin extracting device 30 and causes the failure display unit 53 to generate a failure. The upper lamp 51 is turned on while displaying.

  In the present embodiment, a bobbin storage device 36 that collects the empty bobbin extracted by the bobbin extraction device 30 is provided. The bobbin storage device 36 is also provided with a sensor for detecting that the empty bobbin extracted and collected is full. By the detection of this sensor, it is possible to detect in advance that the bobbin is likely to overflow from the bobbin housing device 36 and deal with it. For example, when the bobbin storage device 36 is full, an empty bobbin discharged from the bobbin extraction device 30 may be temporarily discharged to a bobbin collection box with a remaining yarn. Thereby, overflow of the bobbin accommodation device 36 can be prevented. Since the bobbin with remaining yarn is a post-process and goes through a yarn removing step, it can be processed without any problems even if empty bobbins are mixed.

  A plurality of bobbin storage devices 36 may be provided. For example, two main empty bobbin recovery boxes and a secondary empty bobbin recovery box may be provided. In this case, the recovered empty bobbin is recovered in the main empty bobbin recovery box, and the auxiliary empty bobbin recovery box is recovered only when the main empty bobbin recovery box is full. Switching between the main empty bobbin recovery box and the auxiliary empty bobbin recovery box is performed by a branch portion 35 a provided in the bobbin chute 35.

  Further, the empty bobbin may be caught by the branching portion 35a provided on the bobbin chute 35 and stay. This stagnation can be detected by a stagnation bobbin detection sensor provided in the bobbin extraction device 30 as appropriate. When the stay of the empty bobbin is detected by the staying bobbin detection sensor, the control unit 60 drives the branch part 35a to eliminate the catching of the empty bobbin. If the trapping of the empty bobbin cannot be resolved even by driving the branch portion 35a, the control unit 60 stops the bobbin extraction work by the bobbin extraction device 30, displays the occurrence of the failure on the failure display unit 53 and turns the upper lamp 51 on. Light up.
