It is for detection of the sensor that has or not residual yarn R on the bobbin B that yarn has or not sensor 5.Whether amount of thread sensor 6 is to be sensor more than the specified amount for detection of the amount that is had or not sensor 5 to detect the residual yarn R on the bobbin B of residual yarn R by yarn.
Describe in more detail, such as Fig. 1, shown in Figure 7, residual yarn remove two matrix parts 21,22, rotatable parts 23 of mechanism 11 and three remove pawl unit 24, bobbin press device 3 below, be provided with the track 101 that extends along the above-below direction of Fig. 7.Track 101 is connected with processing bobbin feed path 102 in an end (upper end among Fig. 7), and (bottom among Fig. 7) is connected with processing bobbin discharge path 103 in another end.Track 101, processing bobbin feed path 102 and processing bobbin discharge path 103 are used for pallet 100 is moved, and bobbin B is to be bearing in above-below direction the upper end of pallet 100 as axial upright posture.
Then, supply with the supply end of yarn not shown automatic bobbin winder etc. and the bobbin B that is discharged from from processing bobbin feed path 102 to track 101.In addition, as described later, discharge bobbin B from track 101 to processing bobbin discharge path 103.
Yarn has or not sensor 5 to possess the turning cylinder 5a that extends along the vertical direction, and turning cylinder 5a can be bearing on the installing component 104 that is installed on the body 1a rotationally.In addition, the position that yarn has or not sensor 5 to stagger with turning cylinder 5a in overlooking possesses the contact part 5b that extends along the vertical direction, contact part 5b is configured in the track 101, extract position (position of the bobbin B that is surrounded by long and short dash line of Fig. 7) more by near the part of processing bobbin feed path 102 sides (upside of Fig. 7) than residual yarn, this residual yarn extraction position be in residual yarn remove the matrix part 21,22 of mechanism 11, rotatable parts 23 and three remove pawl unit 24, bobbin press device 3 almost under.
And, existing in the situation of residual yarn R at the bobbin B of this part by track 101, residual yarn R contacts with contact part 5b, and yarn has or not sensor 5 to rotate centered by turning cylinder 5a thus.On the other hand, in the situation that does not have residual yarn R, bobbin B does not contact with contact part 5b.Thus, have or not sensor 5 whether centered by turning cylinder 5a, to rotate according to yarn, can detect and have or not residual yarn R on the bobbin B.
And, having or not sensor 5 to detect in the situation of residual yarn R at bobbin B by yarn, next illustrate, based on the detection of the amount of the residual yarn R of amount of thread sensor 6.On the other hand, having or not sensor 5 not detecting on the bobbin B in the situation of residual yarn R by yarn, the detection of the amount of the residual yarn R that does not next illustrate and the extraction of residual yarn R described later, and this bobbin B directly is discharged to processing bobbin discharge path 103, and be transported to for the Yarn reeling device that yarn is wound up on the bobbin B from bobbin transport path 103.
Amount of thread sensor 6 is that luminous element and photo detector are in abutting connection with the optical sensor of configuration, so-called reflection-type, towards following bobbin B irradiation light: to track 101, extract the position than above-mentioned residual yarn more by Cylinder feeder path 102 sides (upside of Fig. 7) and than being provided with among the bobbin B that part that yarn has or not sensor 5 more transports by the part of processing bobbin discharge path 103 sides (downside of Fig. 7), have or not sensor 5 to detect the bobbin B of residual yarn R by yarn.Describe in more detail, amount of thread sensor 6 is towards the part than the top a little side in bottom of being positioned at of bobbin B, the light of irradiation and the almost identical color of bobbin B.In addition, the color of the color of bobbin B and yarn different (for example the color of bobbin B is that color red, yarn is white).
At this moment, amount at the residual yarn R of bobbin B is more, and bobbin B, existed in the situation of residual yarn R by the part of the luminous element of amount of thread sensor 6 irradiation, reflected by residual yarn R from the light of the luminous element irradiation of amount of thread sensor 6, this reflected light is subjected to light by the photo detector of amount of thread sensor 6.On the other hand, amount at the residual yarn R of bobbin B is less, and only exist in the situation of residual yarn R in the low part of light bobbin B, that shine than the luminous element from amount of thread sensor 6, light from the irradiation of the luminous element of amount of thread sensor 6, although be radiated on the outer peripheral face of bobbin B, but by the reflection of the outer peripheral face of bobbin B, therefore in the photo detector of amount of thread sensor 6, be not subjected to light to light.
Thus, in amount of thread sensor 6, whether according to being subjected to light to arrive above-mentioned reflected light in photo detector, whether the amount that can detect the residual yarn R on the bobbin B is more than the specified amount (amount corresponding with the height of the light that shines from luminous element).
And, in the situation that the amount of residual yarn R is lacked than specified amount, bobbin B is sent to and processes bobbin discharge path 103 after being carried out the next extraction of the residual yarn R of explanation, and is transported to for the Yarn reeling device that yarn is wound up on the bobbin B from processing bobbin discharge path 103.On the other hand, under the amount of residual yarn R is situation more than the specified amount, do not carry out the extraction of residual yarn R, process bobbin discharge path 103 and directly deliver to, and return automatic bobbin winder from processing bobbin discharge path 103, in automatic bobbin winder from this Cylinder feeder yarn.
Then, the method for using residual-yarn removing device 1 to remove the residual yarn R of bobbin B is described.Herein, below the residual yarn R's of explanation removes, as mentioned above, only following bobbin B is carried out: from process the bobbin B that bobbin feed path 102 transports to track 101, have or not sensor 5 to detect residual yarn R and be bobbin B more than the specified amount by the amount that amount of thread sensor 6 does not detect residual yarn R by yarn.Carry out the bobbin B that removes of residual yarn R, along track 101 be transported to residual yarn remove the matrix part 21,22 of mechanism 11, bobbin press device 3 almost under residual yarn extract the position, and before residual yarn R is extracted during, static on this position.
On the other hand, in residual yarn draw-out device 2, under the state before the extraction of carrying out residual yarn R, such as Fig. 2～shown in Figure 5, be arranged on three guide members 33 on the rotatable parts 23, lay respectively in the corresponding guiding groove of removing pawl unit 24 47, with respect to matrix part 21,22 radially be positioned at a most inboard end near, be arranged on the elastic portion 43a of the leading section of removing pawl 43, with respect to matrix part 21,22 radially be positioned at than the outer peripheral face of bobbin B more in the outer part.In addition, remove pawl 43 with respect to the state of radially isolating from the outer peripheral face of bobbin B of bobbin B, be equivalent to isolated condition of the present invention for this three.
In addition, in cylinder 12, piston 12a is positioned at that to make luminous element 72 and photo detector 73a be the position of almost identical height.At this moment, residual yarn is removed mechanism 11 and is positioned at more closer to the top than the upper end of bobbin B.That is, photo detector 73a is arranged on residual yarn and removes on mechanism 11 height when being positioned at than closer to the top certain in the upper end of bobbin B height, identical with luminous element 72.
In addition, in bobbin press device 3, pressing component 81 is positioned at more closer to the top than the upper end of bobbin B.In addition, in residual yarn regenerative apparatus 4, as shown in Figure 1, cartridge 91 becomes almost upright attitude, and is housed in the inside of body 1a.Thus, cartridge 91 can not hinder the conveying of the bobbin B on the track 101 or make bobbin B can not be configured in above-mentioned residual yarn and extract on the position.
Then, when the bobbin B that should remove residual yarn R is extracted the position to above-mentioned residual yarn and transported, drive cylinder 12, as among Fig. 8 by shown in the arrow A 1 like that, make piston 12a drop to luminous element 72 and photo detector 73d becomes almost identical height.At this moment, residual yarn is removed mechanism 11 and is dropped to and remove pawl 43 (removing pawl unit 24) and come the height almost identical with the bottom of bobbin B.That is when, photo detector 73d is arranged on and removes pawl 43 and be positioned at the almost identical height in the bottom of bobbin B, with the almost identical height of luminous element 72 on.
In addition, on matrix part 21,22, be formed with through hole 21a, 22a in its substantial middle section this moment as mentioned above, and therefore when making residual yarn remove mechanism's 11 decline, bobbin B is by through hole 21a, 22a.Therefore, bobbin B can not remove mechanism 11 with residual yarn and contacts.
And, residual yarn remove that mechanism 11 descends almost simultaneously, as among Fig. 8 by shown in the arrow A 2 like that, in bobbin press device 3, drive cylinder 82 and make pressing component 81 drop to the chimeric position, upper end of recess 81a and bobbin B.
Then, remove in the mechanism 11 at residual yarn, by driving cylinder 26 as among Fig. 9 by making like that piston 26a elongation shown in the arrow A 3, swivel arm 25 is rotated along the anticlockwise direction among the figure.So, clip turning cylinder 61 and be positioned at the part that is formed with slotted hole 62 piston 26a opposition side, swivel arm 25, shown in arrow A 5 like that in the figure left move.Thus, be entrenched in chimeric pin 32 and the perforation parts 31 that chimeric pin 32 is installed in the slotted hole 62, the clockwise direction along pilot hole 21b, 22b to Fig. 9 moves.Thereupon, remaining two the perforation parts 31 also clockwise direction along pilot hole 21b, 22b to Fig. 9 move, and by three movements that connect parts 31, rotatable parts 23 such clockwise direction to Fig. 9 shown in arrow A 6 rotates.
When rotatable parts 23 so rotate, be arranged on three guide members 33 on the rotatable parts 23, respectively as among Figure 10 by shown in arrow A 7a～A7c like that, along the guiding groove 47 of removing pawl unit 24 (slide unit 41) (guide surface 47a, 47b) of correspondence, move to guiding groove 47 with respect to matrix part 21,22 radially be positioned at the outside another end near.
At this moment, three connect parts 31 and insert and lead in pilot hole 21b, 22b, so guide member 33 can not be upwards mobile at matrix part 21,22 footpath.Therefore, remove pawl unit 24 (slide unit 41) for three, as among Fig. 9 by shown in arrow A 8a～A8c like that, move along the radially inner side of guide rail 46 to bobbin B, be arranged on the elastic portion 43a of the leading section of removing pawl 43, be pushed on the outer peripheral face of bobbin B.In addition, at this moment, remove pawl 43 by the radially inner side application of force of spring 44 to bobbin B, therefore remove the elastic portion 43a of pawl 43 and the outer peripheral face close contact of bobbin B.And, remove the residual yarn R that pawl 43 can keep bobbin B with removing by three thus.In addition, this three states of removing on the outer peripheral face that pawl 43 is pushed to bobbin B are equivalent to contact condition of the present invention.
At this, in the present embodiment, the mechanism that guide member 33 and guiding groove 47 are combined is equivalent to cam mechanism of the present invention, and the force transformation that this cam mechanism rotates rotatable parts 23 is to remove pawl unit 24 in bobbin mobile power upwards directly.In addition, the mechanism with this cam mechanism and rotatable parts 23 and swivel arm 25 combine is equivalent to transmission mechanism of the present invention, and this transmission mechanism is delivered to three with the propulsive effort of cylinder 26 and removes pawl unit 24.In addition, the mechanism that this transmission mechanism and cylinder 26 are combined is equivalent to travel mechanism of the present invention, and this travel mechanism removes on the outer peripheral face that pawl 43 is pushed to bobbin B three and removes the contact condition (state of Fig. 8) of residual yarn R and three and remove pawl 43 and switch from the isolated condition (state of Fig. 4) of the outer peripheral face isolation of bobbin B.
Then, under this state, drive cylinder 12, make piston 12a rise to luminous element 72 and come the height identical with photo detector 73c.At this moment, residual yarn is removed mechanism 11 and is risen to and remove pawl 43 and come the height identical with bobbin B certain part midway.That is when, photo detector 73c is configured in and removes pawl 43 and come the height identical with bobbin B certain part midway, with the almost identical height of luminous element 72 on.
In addition, remove the rising of mechanism 11 by this residual yarn, with the residual yarn R that removes the bobbin B that pawl 43 contacts, along axially being lifted upward of bobbin B.At this moment, the upper end of the bobbin B parts 81 that are pressed are pressed, so bobbin B can not be lifted together with residual yarn R.
Then, make three to remove pawl 43 and move to the radial outside of bobbin B by driving cylinder 26, return thus above-mentioned isolated condition (state of Fig. 2～Fig. 4), same with above-mentioned situation afterwards, make residual yarn remove mechanism 11 by cylinder 12 and drop to position shown in Figure 8.Then, same with above-mentioned situation, make three to remove pawl 43 and move to the radially inner side of bobbin B by driving cylinder 26, become thus above-mentioned contact condition (state of Fig. 9), under this state, drive cylinder 12 and make residual yarn remove mechanism's 11 risings, and lift the residual yarn R of bobbin B.
But, at this moment, make piston 12a rise to luminous element 72 and come the height identical with photo detector 73b.At this moment, residual yarn is removed mechanism 11 and is risen to position high when removing pawl 43 and coming bobbin B ratio midway and rose last time.That is, photo detector 73b is configured in the top a little side than photo detector 73c.
Then, again return above-mentioned isolated condition, same with above-mentioned situation afterwards, make residual yarn remove mechanism 11 by cylinder 12 and drop to position shown in Figure 8.Then, again become above-mentioned contact condition, drive afterwards cylinder 12 and as among Figure 11 by shown in the arrow A 9 like that, make piston 12a rise to luminous element 72 and come the height identical with photo detector 73a.Thus, residual yarn is removed mechanism 11 and is risen to and remove pawl 43 (removing pawl unit 24) than the top side's of bobbin B position.
And, at this moment, in the timing of removing pawl 43 and coming the height identical with the upper end of bobbin B, as among Figure 11 by shown in the arrow A 10 like that, drive cylinder 82 and that pressing component 81 is risen to is more closer to the top than the upper end of bobbin B.
Thus, the residual yarn R of bobbin B extracts from bobbin B by being removed by residual yarn that mechanism 11 lifts, and removes pawl 43 by three and remove above bobbin B.In addition, this moment, by rising and the decline of repeatedly removing pawl 43, the residual yarn R with bobbin B extracted from bobbin B after each a little ground lifts upward thus, therefore can extract residual yarn R from bobbin B reliably as mentioned above.
Then, be extracted the bobbin B of residual yarn R, carried towards processing bobbin discharge path 103 from track 101, afterwards by driving cylinder 92 as among Figure 12 by shown in the arrow A 11 like that, the clockwise direction of cartridge 91 in the figure rotated, cartridge 91 is tilted to reclaim mouthful 91b to come to remove pawl unit 24 almost under.Then, by returning above-mentioned isolated condition, and the contact of removing 43 couples of residual yarn R of pawl, afterwards as among Figure 13 by shown in the arrow A 12 like that, pressing component 81 is descended by deadweight.
So, pressing component 81 is by removing the zone that pawl 43 surrounds by through hole 21a, 22a and three, and drops to than three and remove pawl 43 on the lower, at this moment, the residual yarn R that is disengaged based on three contacts of removing pawl 43 is pressed downwards and is fallen by pressing component 81.Then, the residual yarn R that has fallen is imported residual yarn and reclaims the 91a of path and be attracted from reclaiming a mouthful 91b.
Afterwards, by cylinder 82 pressing component 81 is risen, and drive cylinder 92 cartridge 91 is rotated along the anticlockwise direction of Fig. 1, return thus the state of Fig. 1.Then, carry out successively similarly in the following extracting to residual yarn the removing of residual yarn R of the bobbin B that the position transports.
