As shown in Figure 1, adopt the doffing system of above-mentioned single hammer self doff device 57, possess following structure: the mechanism 3 of doffing that on every hammer of a plurality of coiling hammers 2 that constitute false twist processing machine, is provided with; Supply with these mechanism's 3 propulsive efforts that doff, on a plurality of coilings hammer 2, be provided with respectively hammer common axle drive shaft 4,5,6 into shape; The magnetic clutch 7,8,9 that is connected with the mechanism 3 of doffing of corresponding hammer 2 on this axle drive shaft; Detect the detecting device of package 10 sizes; During doff package is divided into the sorting machine of big tube and little tube.This sorting machine can set to the size of empty paper tube from full tube for the benchmark of big tube and little tube distinguishing package 10 with changing.

On the hammer 2 of reeling, be provided with: the winding roller 12 that makes paper tube or package 10 depend on wipe contact to rotate, the harness threading frame 11 of maintenance paper tube or package 10, the reciprocating traverse device 13 that the yarn of being reeled is traversed.In addition, on the hammer 2 of reeling, be provided with the time meter that doffs (length control device) 18 of measuring coiling length, the Length Control that can carry out package 10.That is: can carry out instrumentation with the time to the coiling length of the yarn of constant speed traveling, detect full tube, the magnetic clutch that is used for doff then moves.

The mechanism 3 of doffing carries out following action: harness threading frame 11 close and launch action, the action that empty paper tube is supplied with the action of harness threading frame 11 and hang yarn on the paper tube that is held on the harness threading frame 11.Above-mentioned action is that the anglec of rotation of corresponding cam is carried out.In addition, wireline reel 2 is provided with button PB, can make the cam that stops to begin to rotate with this button again.

Sorting machine of the present invention is when broken yarn, distinguishes package and carry out the doff action after big and little.At this moment, the package of big tube is moved in the accumulator equally with full tube, and the package of little tube is keeping with the state that floats from winding roller 12.As the detecting device that detects package size (coiling amount), can be position or the rang sensor of surveying the ascending amount of the harness threading frame 11 of growing up according to package, also can be the external diameter sensor of measuring the package external diameter.Here, the time meter 18 that will doff is used for detecting device.The time meter 18 that doffs of measuring the amount (length) of yarn is used to distinguish big tube and little size detection device, so be set with a reference value B.A reference value B is generally A＞B＞0 also can be set at B=0 or B 〉=A.

The action of the doff device when having set full tube value A and a reference value B (A＞B＞0), the whole pie graph of overview that can be by processing sequence in the continuous operation mode of Fig. 3 and the false twisting machine of Fig. 4 is illustrated.And operation mode is to carry out doff after detecting full tube with the time meter 18 that doffs at every turn continuously, and the empty paper tube of supply is proceeded the common doff pattern of the coiling of new package 10.

1. the package of full tube

When the count value X of time meter 18 of doffing reaches full tube value A, carry out common doff and move, and package 10 is removed to accumulator 60.Common doff action is during full tube, and harness threading frame 11 is risen, open on this position package is discharged after, at the paper tube of harness threading frame 11 clamping skies.Harness threading frame 11 is descended, make paper tube and winding roller wipe contact, the rotation by the arm 23 of entrying is suspended to the paper tube end with yarn.Then, begin once more to reel by the rotation of winding roller 12 and the reciprocating traverse of reciprocating traverse device 13.

2. broken yarn package

In the above-mentioned continuous operation mode, if before the time meter 18 that doffs detects full tube, when broken yarn occurring, yarn detector 54 detects broken end, the yarn cutting device 43 that is used in the entrance configuration of yarn feeding Y cuts off yarn, prevents the yarn end when feeding the winding of roller 44, lights the outer broken yarn indicator lamp of figure.

Detect moment of broken yarn at yarn detector 54, the count value X and a reference value B of the time meter 18 that will doff compare, and broken end yarn package 10 is divided into above the big tube of a reference value B and little of discontented a reference value B.

The occasion of big tube, at the state of opening harness threading frame 11, the cam of the mechanism 3 that stops to doff was so package 10 falls into accumulator 60 when harness threading frame 11 was risen.By the broken yarn indicator lamp light know that the operating personal that broken yarn occurs is wrapped in loose thread on the yarn road that comprises the processed yarn remove or connect yarn etc.After attracting to keep the yarn end on the suction pipe that constitutes the doff device, be pressed into button PB.Button PB is in the ON state, and the harness threading frame 11 that is in halted state on the position of discharging package 10 begins action, automatically entrys to the empty paper tube of harness threading frame 11 supplies with to paper tube, and reeling begins once again.Begin interlock once more with this, the time meter 18 that doffs resets.

When Counter Value X did not reach a reference value B and just broken yarn occurs, the action of the doff of little tube was: harness threading frame 11 is risen, under harness threading frame closing state cam is stopped operating.The state that unclamps from take up roll 12 that is wrapped in of this little tube remains in the harness threading frame 11.This state is to impel operating personal to remove the state of package.The operating personal of seeing the broken yarn indicator lamp and breaking end and handle reaches from maintenance channel 58 sides, holds on this package from below, presses the button PB.When operating personal presses the button PB, a little rotation of cam, harness threading frame 11 opens, and operating personal heads on package and takes out.After connecing the yarn operation, operating personal and the aforementioned PB that similarly presses the button once more, the doff device carries out the action of entrying to paper tube.

Like this, Counter Value is that accumulator is moved in the full package of full tube value A and the big broken end yarn package that surpasses a reference value B in coiling.The broken end yarn package that does not surpass a reference value B is keeping as little tube.In full tube recovery approach 59 sides indicating devices such as little tube indication lamp according to the indication of difference device can be set also, but if when the operating state of harness threading frame 11 is judged, operating personal there is no need to make an inspection tour on full tube recovery approach 59.

Have, set the occasion of a reference value B=0, Counter Value is bound to surpass a reference value B, so the yarn package of all breaking end is all moved into accumulator.In addition, set the occasion of a reference value B 〉=full tube value A, Counter Value can not surpass a reference value B, so, have only the package of full tube to be moved into accumulator, the yarn package of all breaking end is keeping.

Like this, because a reference value B can change, operating personal not only can change the size of the package that remove arbitrarily, and according to a reference value B=0, the special processing of setting the package of the yarn that can will all break end of A is united.

Below, the anglec of rotation of cam and the relation of each action are illustrated.

As shown in Figure 2, when cam from angle θ ₀=0 °, to angle θ 1, harness threading frame 11 begins to rise, and fully rises during to angle θ 2.At this moment, harness threading frame 11 is not opened, and the occasion of little tube stops at this cam.When pressing the button PB, a little rotation of cam is opened to angle θ 3 preceding harness threading framves 11, and cam stops once more.Broken end yarn and stop for the first here cam of the occasion of big tube.Begin to supply with paper tube when pressing the button PB, harness threading frame 11 is closed when soon arriving angle θ 4.And then 11 declines of harness threading frame finish before arriving angle θ 5.6=360 ° of angle θ, all releases.The occasion of full tube is not finished whole actions midway with stopping from angle θ 0 to angle θ 6.

As mentioned above, the each several part sequence of operation of the mechanism of doffing of single hammer self automatic doffer is the anglec of rotation of corresponding cam, so, if decide the stop angle of cam, different packages can be handled respectively according to big tube and little differentiation.

The present invention can bring into play following excellent results.

(1) package is distinguished according to its size, can be removed big or small unsuitable package, also can be used in the aspect that grades of package.And judge it is objective, steady quality.

(2) with little state that is in maintenance, removing little tube easily, particularly moves into the package behind the doff in the board of the form in the accumulator at the hammer back side, entrying operates in the previous action of hammer, thus little tube remove operation and the operating continuity of entrying good, operating efficiency improves.

(3) benchmark of package being divided into big tube and little tube can be set in full tube size between the size of empty paper tube, thus not only can at random change benchmark, and the processing of the yarn package of all breaking end can be united.
