As it has been described above, in the present embodiment, only by single driving source i.e. stepper motor 100 is entered Row cutting, it becomes possible to carry out supply bobbin 21 acceptance, unwinding attitude supply bobbin 21 holding (and The adjustment of this unwinding attitude) and the discharge of supply bobbin 21.
Then, with reference to Figure 10 to Figure 14 to after supplying supply bobbin 21 to bobbin set section 10 to opening Flow process till the winding of beginning yarn 20, particularly supply bobbin 21 bit motion is illustrated.Figure 10 is to represent the flow chart of the process that winder unit 4 is carried out when being supplied to supply bobbin.Figure 11 is to figure 14 is the side view to bit motion that supply bobbin 21 is described.It addition, by this flow chart and shown below The process of flowchart representation is an example, even if perhaps front and back exchanging processing sequence in change processes In the case of, sometimes it also is able to obtain the effect of the present invention.
Stepper motor control portion 102 makes stepper motor 100 drive, and makes the movement in advance of main core components 80 be Accept attitude.When receiving the instruction of the winding starting yarn 20, unit control portion 50 makes bobbin Feedway 60 carries out the supply (S101) of supply bobbin 21.As shown in Figure 11 (a), fill from Cylinder feeder Put the supply bobbin 21 of 60 supplies, (standby to accept attitude specifically by bobbin maintaining part 110 Main core components 80 and auxiliary wick parts 90) accept.Then, stepper motor control portion 102 makes bobbin protect Hold rearwardly side, portion 110 and rotate (S102).
In the winder unit 4 of present embodiment, rotate making bobbin maintaining part 110 rearwardly side Time, according to the axial length (the hereinafter referred to as length of supply bobbin 21) of the core pipe 21a of supply bobbin 21 And carry out different process.In the present embodiment, unit control portion 50 is according to conical surface portion detection sensing The testing result of device 74, it is judged that whether supply bobbin 21 is longer than specific length (S103).Therefore, this enforcement The conical surface portion detection sensor 74 of mode works as length information obtaining section.Here, so-called regulation Length, with the core pipe 21a of the minimum that supply bobbin 21 can be detected by conical surface portion detection sensor 74 Length corresponding.
Specifically, when making bobbin maintaining part 110 rearwardly side rotate, in conical surface portion detection sensing In the case of device 74 detects supply bobbin 21, supply bobbin 21 has crossed conical surface portion detection sensor 74 Detection range (with reference to Figure 11 (a)).Therefore, it is possible to be judged as a length of specific length of supply bobbin 21 Above.On the other hand, when making bobbin maintaining part 110 rearwardly side rotate, in conical surface portion, detection passes In the case of sensor 74 is not detected by supply bobbin 21, supply bobbin 21 has passed through conical surface portion detection sensor The lower section (with reference to the chain-dotted line of Figure 13 (a)) of the detection range of 74.As a result, it is possible to be judged as supply bobbin 21 Length less than specific length.
First, in the case of more than a length of specific length of supply bobbin 21 in the judgement of S103 The process carried out illustrates.In this case, stepper motor control portion 102 makes bobbin maintaining part 110 rearwardly side rotations, make supply bobbin 21 the most upright (S105).In the present embodiment, at S105 In, the front wheel driving stepper motor 100 of initial point detected at above-mentioned origin sensor 101, thus make for yarn Pipe 21 is upright.It addition, in this stage, as long as supply bobbin 21 becomes general upright posture and is sufficient for, So not carrying out the strict gesture stability of supply bobbin 21.
Additionally, unit control portion 50 makes brush portion 11b preventing contracting yarn feeding device 11 and supply bobbin 21 Upper part contact (with reference to Figure 11 (b)), give suitable tension force to yarn 20, prevent contracting yarn (S105).Afterwards, stepper motor control portion 102 makes bobbin maintaining part 110 rotate, so that supply bobbin 21 topple over (S106) to face side is some again.Then, conical surface portion detection sensor 74 detecting During supply bobbin 21, unit control portion 50 makes bobbin keep the rotation of all 110 to stop (S107, Figure 12 (a)).
Additionally, storage part 52 storage that unit control portion 50 is possessed has the information being expressed as follows content (hereinafter referred to as adjusting distance): from position supply bobbin 21 being detected by conical surface portion detection sensor 74 Put, made stepper motor 100 drive several pulsed quantity then can make supply bobbin 21 and unwinding reference position Alignment.In the present embodiment, supply bobbin 21 to be detected by conical surface portion detection sensor 74 Position on the basis of, make supply bobbin 21 move above-mentioned adjustment distance (return the most round about Return), thus make supply bobbin 21 be directed at unwinding reference position.Therefore, in this manual, sometimes " benchmark position is started by detecting that by conical surface portion detection sensor 74 the position of supply bobbin 21 is referred to as Put ".So, conical surface portion detection sensor 74 is also as in order to make supply bobbin 21 and unwinding reference position The position detection part being directed at and detect this supply bobbin 21 works.
Here, the adjustment distance that storage part 52 is stored is right with the imparting of the kind of the supply bobbin 21 of use Should.Additionally, in the case of more than a length of specific length of supply bobbin 21 and in the case of really not so, Storage part 52 stores above-mentioned adjustment distance respectively.Therefore, unit control portion 50 is following by carrying out Process the adjustment distance determining this time should to use.That is, unit control portion 50 is according to pre-by operator First input, the kind of supply bobbin 21 that is that use, reads the adjustment distance of above-mentioned two situations.Then, By adjustment distance time in two kinds of situations, more than a length of specific length of supply bobbin 21, it is determined as this Secondary used adjustment distance.
Then, unit control portion 50 is according to the adjustment distance determined, to stepper motor 100 output regulation Umber of pulse, makes bobbin maintaining part 110 rearwardly side rotate (S108, Figure 12 (b)).
Thereby, it is possible to make the central shaft of supply bobbin 21 and the central shaft (imaginary line L1) of movable member 72 Alignment (can make supply bobbin 21 be directed at unwinding reference position).Therefore, auxiliary in supply bobbin 21 and unwinding Help the air ring that can form suitable shape between device 12, it is possible to suitably keeping from supply bobbin 21 The winding of yarn 20 is carried out while the tension force of the yarn 20 of unwinding.
Then, to the length of supply bobbin 21 in the judgement of S103 less than institute in the case of specific length The process carried out illustrates.In this case, unit control portion 50 make supply bobbin 21 upright it Before or afterwards, drive Lift Part drive division 75 and make Lift Part 73 decline ormal weight (such as 10mm)(S104).Thus, sensor 74 and Lift Part detect in movable member 72 and conical surface portion 73 decline ormal weight (with reference to the chain-dotted line of Figure 13 (b)) together.It addition, about now making Lift Part 73 The distance declined, operator pass through operating unit input unit 18 or body input unit 8 etc., it is possible to enter The setting of row value and change.
Then, as described above, unit control portion 50 makes supply bobbin 21 the most upright (S105), makes to prevent Brush portion 11b of contracting yarn feeding device 11 is only occurred to contact with the upper part of supply bobbin 21.Afterwards, stepping Motor control part 102 makes bobbin maintaining part 110 rotate, so that supply bobbin 21 is again some to face side Topple over (S106).It addition, make the control that Lift Part 73 declines, make bobbin maintaining part 110 to just Side, face completes before rotating.Additionally, start the timing of the control making Lift Part 73 decline, can With before making supply bobbin 21 upright, can also be after making supply bobbin 21 upright.It addition, make In the case of starting to make the control that Lift Part 73 declines after supply bobbin 21 is upright, at Lift Part The decline of 73 completes to need before to make supply bobbin 21 static.
By making Lift Part 73 and conical surface portion detection sensor 74 decline, even if thus in supply bobbin The length of 21 is less than in the case of specific length, and conical surface portion detection sensor 74 also is able to detect for yarn Pipe 21.Therefore, as described above, when supply bobbin 21 being detected by conical surface portion detection sensor 74, Unit control portion 50 makes the rotation of bobbin maintaining part 110 stop (S107, Figure 14 (a)).
Then, unit control portion 50 determines the adjustment distance that this time should use.Specifically, unit control Portion 50 processed, according to the kind of supply bobbin 21 set in advance, reads the adjustment distance of above-mentioned two situations, And adjust distance from the two and the length of supply bobbin 21 is determined less than adjustment distance during specific length It is set to the adjustment distance this time used.Then, unit control portion 50 according to determine adjustment distance, to Stepper motor 100 exports predetermined pulse number, makes bobbin maintaining part 110 rearwardly side rotate (S108, figure 14(b))。
Thus, though shorter and examine as position at the core pipe 21a of the supply bobbin 21 owing to being supplied In the case of the conical surface portion detection sensor 74 in survey portion is unable to detect that supply bobbin 21, by making this Conical surface portion detection sensor 74 declines, and also thus is able to detect on shorter core pipe 21a winding The supply bobbin 211 of yarn.Therefore, it is possible to make supply bobbin 21 be directed at unwinding reference position without problems.
It addition, in the case of the kind of the supply bobbin 21 used changes, by unit input unit 18 carry out suitable input, it is possible to suitable adjustment distance is set to depositing of unit control portion 50 Storage portion 52.In addition it is also possible to body input unit 8 is carried out this input, replace unit input unit 18 carry out this input.In this case, machine member control apparatus 7 will enter into the interior of body input unit 8 Hold and send to each winder unit 4.Thereby, it is possible to the unit control portion 50 to each winder unit 4 Set suitable adjustment distance uniformly.
As it appears from the above, the winder unit 4 of present embodiment possesses bobbin maintaining part 110, as length Conical surface portion that information acquiring section and position detection part work detection sensor 74, storage part 52 and Unit control portion 50.Bobbin maintaining part 110 keeps supply bobbin 21.Conical surface portion detection sensor 74 takes Information i.e. length information that must be relevant with the axial length of supply bobbin 21.Conical surface portion detection sensor 74 The position of the supply bobbin 21 that bobbin maintaining part 110 is kept can be detected.Storage part 52 is stored in yarn The position of supply bobbin 21 should be kept to unwind the information of reference position and cone is set during the winding of line 20 The information of the position of face detection sensor 74.Unit control portion 50 is to carry out according to length information Make the control that conical surface portion detection sensor 74 moves, so that this conical surface portion detection sensor 74 can be examined Measure the supply bobbin 21 that bobbin maintaining part 110 is kept, according to the detection of conical surface portion detection sensor 74 The storage content of result and storage part 52 carries out the control making supply bobbin 21 move, so that this is for yarn Pipe 21 is directed at target location.
Thus, by the length information utilizing conical surface portion detection sensor 74 to obtain, it is possible to make this conical surface Portion's detection sensor 74 moves to the position corresponding with the length of supply bobbin 21.Therefore, though In the case of the length of supply bobbin 21 exists deviation, conical surface portion detection sensor 74 is in supply bobbin 21 Also will not be failed in detection, therefore, it is possible to reliably carry out making that supply bobbin 21 is directed at target location is dynamic Make (to bit motion).
Additionally, in the present embodiment, conical surface portion detection sensor 74 doubles as length information obtaining section With position detection part both sides.Therefore, it is possible to minimizing number of probes, composition is made to simplify and cut down cost.
Then, with reference to Figure 15 to Figure 19, the first variation of above-mentioned embodiment is illustrated.Figure 15 is to represent the process that winder unit 4 is carried out when being supplied to supply bobbin 21 in the first variation Flow chart.Figure 16 and Figure 17 is the side-looking to bit motion that the supply bobbin 21 in the first variation is described Figure.Figure 18 is the side view representing the example that face sensor 58 is used as length measurement sensor. Figure 19 is the figure of the example representing the length measurement sensor being arranged on bobbin supply apparatus 60.
It addition, in this variation, for parts same or similar with above-mentioned embodiment, attached Figure gives identical labelling, and sometimes omits the description.Additionally, in this variation, in order to easily Observe supply bobbin 21 around, and eliminate the diagram preventing contracting yarn feeding device 11.
That is, in the composition (Figure 11) of above-mentioned embodiment, conical surface portion detection sensor 74 is used as Length information obtaining section.On the other hand, it is configured in this variation, as length information obtaining section, Use the sensor outside conical surface portion detection sensor 74.Specifically, it is configured in this variation, On the basis of the composition of above-mentioned embodiment, as shown in figure 16, possesses length measurement sensor 57.
Length measurement sensor 57 after bobbin set section 10 accepts bobbin to making supply bobbin 21 rotate And become the period till upright posture, it is possible to measure the length of this supply bobbin 21.Specifically, long Degree measurement sensor 57 possesses 4 sensor elements being equal to conical surface portion detection sensor 74.Separately Outward, as conical surface portion detection sensor 74, each sensor element is made up of light-projecting portion and light accepting part. Additionally, the direction that this 4 sensor elements are arranged, with by during length measurement sensor 57 should The most identical (with reference to the chain-dotted line of Figure 16 (a)) of supply bobbin 21.In the present embodiment, Lift Part The initial position of 73 is set to, and the core pipe 21a of supply bobbin 21 detected at 2 sensor elements State under, conical surface portion detection sensor 74 can most preferably detect the core pipe 21a of supply bobbin 21.
In this composition, when supply bobbin 21 is by length measurement sensor 57, supply bobbin detected The number of the sensor element of 21 is the most, then the length of supply bobbin 21 is the longest.Therefore, in this variation In, according to the number of the sensor element this supply bobbin 21 being detected, it is possible to somewhat grasp confession The length of spool 21.So, length measurement sensor 57 be not with 2 stages (be whether specify with On) and the length of supply bobbin 21 can be showed with multiple stages more than 3 stages, therefore can The enough length more specifically measuring supply bobbin 21.Hereinafter, it is used as by length measurement sensor 57 Supply bobbin 21 during length information obtaining section bit motion is illustrated.
Unit control portion 50, when receiving the instruction of the winding starting yarn 20, makes Cylinder feeder fill Put 60 supplies (S201 of Figure 15) carrying out supply bobbin 21.As shown in Figure 16 (a), from Cylinder feeder The supply bobbin 21 of device 60 supply is accepted by bobbin maintaining part 110.Then, stepper motor control portion 102 make bobbin maintaining part 110 rearwardly side rotate (S202).Length measurement sensor 57 makes bobbin In the way that maintaining part 110 rearwardly side rotates, length (S203, reference Figure 16 (a) of measurement supply bobbin 21 Chain-dotted line).Then, the length of the supply bobbin 21 of measurement is sent to list by length measurement sensor 57 Control portion 50 of unit.
Unit control portion 50, according to the length of the supply bobbin 21 received from length measurement sensor 57, adjusts The position (S204) of whole apparatus for unwinding 12.It addition, the apparatus for unwinding 12 of this variation possesses Second movable member (the second accessory) 171, replaces fixed component 71.Second movable member 171 It is powered from the driving source omitting diagram, it is possible to move in vertical.Therefore, Two movable members 171 can independently move with Lift Part 73 phase.
The unwinding auxiliary carried out in the length of the supply bobbin 21 measured according to length measurement sensor 57 In the position adjustment of device 12, it may be considered that to various patterns.That is, in order to form the gas of suitable shape Circle, not only position relationship between supply bobbin 21 and movable member 72, supply bobbin 21 (or movable part Part 72) and the second movable member 171 between position relationship the most more important.Particularly, lifting unit is made When part 73 moves significantly, the second movable member 171 is preferably made to move to equidirectional.
Figure 16 represents that the supply bobbin 21 having wound yarn on long core pipe 21a is fed into network The example of yarn machine unit 4.In this example embodiment, when assuming not make apparatus for unwinding 12 move, as Shown in Figure 16 (b), the height of conical surface portion detection sensor 74 can become core pipe 21a and conical surface portion 21b Border near height.In this case, detection sensor 74 in conical surface portion likely detects layer Rather than core pipe 21a, so it is difficult to carry out bit motion accurately.In order to avoid this situation, unit The control portion 50 more than 3 detections in 4 sensor elements constituting length measurement sensor 57 In the case of supply bobbin 21, Lift Part 73 is made to rise (with reference to the chain-dotted line of Figure 16 (b)).Thus, The height of conical surface portion detection sensor 74 becomes the height being able to detect that core pipe 21a, therefore, it is possible to suitable Locality is carried out bit motion.
Additionally, in this variation, be supplied to as this example at long core pipe 21a On wound the supply bobbin 21 of yarn in the case of, unit control portion 50 not only makes on Lift Part 73 Rise, also make the second movable member 171 rise (with reference to the chain-dotted line of Figure 16 (b)).So, by not only Movable member 72 is made also to make the second movable member 171 move to corresponding with the length of supply bobbin 21 Appropriate location, it is possible to more suitably keeping while the tension force of the yarn of supply bobbin 21 unwinding Carry out the winding of yarn 20.
Unit control portion 50 is after have adjusted the position of apparatus for unwinding 12, as described above Make supply bobbin 21 the most upright (S205).It addition, as it has been described above, eliminate in the figure of this variation Prevent contracting yarn feeding device 11, but now make to prevent brush portion 11b and the supply bobbin of contracting yarn feeding device 11 The upper part contact of 21.Afterwards, stepper motor control portion 102 makes bobbin maintaining part 110 rotate, So that supply bobbin 21 topples over (S206) to face side is some again.And, unit control portion 50 is by boring When face detection sensor 74 detects supply bobbin 21, the rotation of bobbin maintaining part 110 is made to stop (S207, Figure 17 (a)).
Here, as described above, obtain adjustment distance according to the storage content of storage part 52, but In this variation, it is possible to obtain the length of supply bobbin 21, institute with multiple stages more than 3 stages With each kind for supply bobbin 21, storage part 52 (the most in a tabular form) store about each The adjustment distance in stage.Additionally, in order to avoid the increase storing content, unit control portion 50 can also Kind, the height of conical surface portion detection sensor 74 and unwinding reference position according to supply bobbin 21, The regulation computing formula stored according to storage part 52 is to obtain adjustment distance.Then, unit control portion 50 umber of pulses specified to stepper motor 100 output according to the adjustment distance calculated, make bobbin maintaining part 110 rearwardly side rotate (S208, Figure 17 (b)).
So, in this variation, according to the supply bobbin 21 the most specifically detected Length, makes to detect sensor 74 as the conical surface portion of position detection part and moves.Therefore, it is possible to reliably Carry out supply bobbin 21 to bit motion.Additionally, in above-mentioned embodiment (Figure 11), be supplied to When having wound the supply bobbin 21 of yarn on the core pipe 21a longer than situation about assuming, sometimes can not be suitable Ground carries out para-position, but in this variation, it is possible to corresponding to having wound yarn on longer core pipe 21a The supply bobbin 21 of line and wound the both sides of supply bobbin 21 of yarn on shorter core pipe 21a.
Alternatively, it is also possible to replace length measurement sensor 57 and use face sensing as shown in Figure 18 Device 58.Face sensor 58 is made up of multiple sensor elements as length measurement sensor 57, but Be not as length measurement sensor 57 by can self contained function sensor element combination constitute, and It is just to be integrally formed the sensor into detecting regulation detection range from initially.In this face sensor 58, Interval between sensor element is extremely short, it is possible to obtain the concrete number of the length of supply bobbin 21. Therefore, it is possible to carry out bit motion more reliably.It is further possible to use by the sensor unit singly organized Part constitutes, detects according to the change of light income the face sensor in region shared by object.
Additionally, in the composition of Figure 16 and Figure 18, to supplying after bobbin set section 10 accepts bobbin Period till spool 21 is upright, measure the length of this supply bobbin 21.Thus, it is not only supply bobbin The length of 21, additionally it is possible to the supply of detection supply bobbin 21 is slipped up and accepts error etc..Although that is, single Unit control portion 50 for give supply bobbin 21 but length measurement sensor 57 or face sensor 58 the most not In the case of supply bobbin 21 being detected, suspect in bobbin magazine rotating disk 62, be not inserted into supply bobbin 21 or cylinder Pipe maintaining part 110 is not appropriately interposed core pipe 21a etc..By detecting this error, it is possible to supply as early as possible Give next supply bobbin 21, it is possible to increase batch efficiency.
The place of configured length measurement sensor is arbitrary, but when being arranged in from bobbin supply apparatus The path of 60 (reception holes of bobbin magazine rotating disk 62) above-mentioned supply bobbin 21 to above-mentioned unwinding reference position Time upper, advantageous on this point of can simplify composition.Such as shown in Figure 19, it is also possible to be configured to, Bobbin detection sensor 59 as length measurement sensor is arranged near bobbin supply apparatus 60. This bobbin detection sensor 59 possesses: the top of the supply bobbin 21 can received bobbin magazine rotating disk 62 Carry out 2 touch sensor (sensor element) 59b detected；And can be to the bottom of supply bobbin 21 Carry out the touch sensor 59a detected.These touch sensors 59a, 59b be installed to be not with bobbin magazine Rotating disk 62 rotates together, even if so bobbin magazine rotating disk 62 rotates, it is also possible to measurement all the time next to The length of the supply bobbin 21 of bobbin set section 10 supply.The touch sensor 59a being arranged in bottom uses In detecting the presence of supply bobbin 21, it is arranged in 2 touch sensor 59b on top for three phases The length of measurement supply bobbin 21.It addition, detect sensor 59 as bobbin, it is possible to use sensing contact Device, it is possible to use contactless sensor.
In the composition of this bobbin detection sensor 59, confession detected at the touch sensor 59a of bottom When 2 touch sensor 59b on spool 21 and top detect supply bobbin 21, the next one is supplied The length of the supply bobbin 21 given is long.Additionally, detect for yarn at the touch sensor 59a of bottom During pipe 21, when in the touch sensor 59b on top, only one detects supply bobbin 21, next The supply bobbin 21 being supplied to is moderate length.Further, the touch sensor 59a inspection in bottom When measuring supply bobbin 21, when being all not detected by supply bobbin 21 in the touch sensor 59b on top, The supply bobbin 21 that the next one is supplied to is for comparatively short.
It addition, in the case of the touch sensor 59a of bottom is not detected by supply bobbin 21, at bobbin Reception hole is not received supply bobbin 21, therefore rotates and the bobbin of bottom detection sensing at bobbin magazine rotating disk 62 Before device 59 is able to detect that supply bobbin 21, do not carry out the sentencing of length of supply bobbin 21 as described above Disconnected.And, unit control portion 50 adjusts unwinding according to the length of bobbin detection sensor 59 detection The position of auxiliary device 12, it is possible to reliably carry out bit motion.
It addition, as shown in figure 19, it is arranged in bobbin supply apparatus 60 at bobbin detection sensor 59 attached In near composition, it is possible in the length than the measurement of stage earlier supply bobbin 21.Therefore, moving back When the position adjustment of auxiliary device 12, there is time margin, it is possible to carry out this adjustment the most limpingly.
As shown above, in the winder unit 4 of the first variation, length measurement sensor 57 leads to Cross measurement and obtain length information.
Thereby, it is possible to the most specifically detect the length of supply bobbin 21, therefore, it is possible to make conduct The conical surface portion detection sensor 74 of position detection part moves to will not be failed in the detection of supply bobbin 21 Position.Therefore, it is possible to more reliable and correctly carry out supply bobbin 21 to bit motion.
Additionally, the winder unit 4 of this variation possesses bobbin supply apparatus 60 and the cylinder of bobbin magazine formula Pipe guide portion 64.Bobbin supply apparatus 60 possesses multiple bobbin reception hole.Bobbin guide portion 64 has The supply bobbin 21 received by bobbin reception hole is directed to the path of navigation of bobbin maintaining part 110.Unit The supply bobbin 21 that control portion 50 is carried out via path of navigation makes bobbin maintaining part 110 accept moves to move back Control around reference position.Length measurement sensor 57 (or face sensor 58, bobbin detection sensor 59), to the phase arrived unwinding reference position after supply bobbin 21 is received to bobbin reception hole Between, measure and obtain length information.
Thereby, it is possible to measurement obtains length information on the path that supply bobbin 21 is generally transported.Therefore, It is no need to the measurement of length information and special path etc. is set, it is possible to prevent winder unit 4 Composition complicate.
Then, the second variation of above-mentioned embodiment is illustrated.
That is, it is configured in above-mentioned embodiment and the first variation, by being measured by sensor And obtain the length of supply bobbin 21, but be configured in this variation, according to by body input unit 8 or The information of unit input unit 18 input, as length information obtaining section and the unit of input length obtaining section Control portion 50 obtains the length of supply bobbin 21.That is, unit control portion 50 supplies yarn according to be previously set The kind of pipe 21 and obtain the length information of supply bobbin 21.
Unit control portion 50 is when obtaining the length of supply bobbin 21, according to the length of this supply bobbin 21, Determine to make apparatus for unwinding 12 (conical surface portion detection sensor 74) when carrying out the para-position of supply bobbin 21 The most standby position.This is carried out certainly in the same manner as the method for explanation in the S204 in the first variation Fixed.Hereinafter, sometimes the position making position detection part the most standby when the para-position of supply bobbin 21 is referred to as Start reference position.As long as the setting of the supply bobbin 21 used is not changed, then in this beginning determined Reference position does not changes.
Winder unit 4 use this start reference position to carry out supply bobbin 21 to bit motion, but make Following 2 kind can be considered for alignment method now.
That is, first method is, when to bit motion, makes to detect as the conical surface portion of position detection part Sensor 74 is the most from starting the method that reference position is moved.That is, if same supply bobbin 21, Then its length will not change significantly, as long as therefore the location-appropriate of sensor 74 is detected in conical surface portion, then Core pipe 21a can be detected without problems in most cases by this conical surface portion detection sensor 74.Cause This, in the method, be not to measure the length of supply bobbin 21 individually and make conical surface portion detect sensor 74 move, but make detection sensor 74 in conical surface portion start state the most static on reference position Under carry out bit motion.Control thereby, it is possible to simplify.
Second method is, measures the length of supply bobbin 21 individually, determines according to this measurement result Conical surface portion detection sensor 74 whether is made to move from starting reference position.Here, as measuring individually The method of the length of supply bobbin 21, it may be considered that use above-mentioned embodiment such use conical surface portion inspection Survey the method for sensor 74, the first variation such use sensor special (length measurement sensor 57 etc.) method.I.e., in the method, unit control portion 50 obtains for yarn as according to setting First length information obtaining section of the length of pipe 21 works.Additionally, conical surface portion detection sensor 74 The second length information obtaining section as the length measuring supply bobbin 21 individually works.And, single Unit control portion 50 in the measurement result according to supply bobbin 21, be judged as at the cone as position detection part When face detection sensor 74 is unable to detect that supply bobbin 21 when being in beginning reference position, carry out Make the control that the position of this conical surface portion detection sensor 74 is changed from above-mentioned beginning reference position.
By using this second method, for the major part in the supply bobbin 21 that supplied, it is possible to no Make to detect sensor 74 as the conical surface portion of position detection part to carry out movably for yarn from starting reference position Pipe 21 to bit motion.On the other hand, in the feelings of the supply bobbin 21 being supplied to length and be typically different Under condition, by making position detection part move to the position corresponding with this supply bobbin 21, thus in these feelings It also is able to carry out without problems para-position under condition.
As shown above, the automatic bobbin winder of the second variation possesses winder unit 4, body controls dress Put 7 and input unit (body input unit 8 and unit input unit 18).Machine member control apparatus 7 controls many Individual winder unit 4.Input unit can input the information relevant with supply bobbin 21.Unit control portion 50 Length information (i.e. working) is obtained as length information obtaining section according to the information being input in input unit. Additionally, unit control portion 50 determines to start reference position according to this length information, carry out making conical surface portion examine Survey sensor 74 and move to start the control of reference position.
Thus, conical surface portion detection sensor 74 is made to move to the beginning benchmark position determined according to input content Put, it is possible to save the length of just acquirement (measurement) this supply bobbin 21 whenever being supplied to supply bobbin 21 Time.Additionally, easily multiple winder unit 4 intensively to be set the length of supply bobbin 21.
