Fig. 3 A and Fig. 3 B show the cross sectional drawing according to an embodiment of the lower part of the air cylinder actuator 31 of an embodiment of the present utility model.In Fig. 3 B, actuator is than extending in Fig. 3 A or raising manyly.As equally, as shown in Fig. 2, actuator 31 can comprise the housing 39 that limits slip cavity 40, and this slip cavity has the bottom of mushroom-shaped,, has different two the coaxial

cylindrical chambers

41,42 of diameter that is.

In this embodiment, wider chamber 41 is above narrower chamber 42.Piston 44 is slidably received in cavity 40.The size and dimension of piston 44 is suitable for or corresponding to chamber 41,42.Piston 44 comprises two overlapping

cylindrical parts

45,46, and these two cylindrical parts have respectively the diameter corresponding to

chamber

41,42, thereby limit totally, is the configuration of mushroom-shaped.The cross-sectional area of wider chamber 41 is corresponding with the cross-sectional area of the wider cylindrical part 45 of piston, and the cross-sectional area of narrower chamber 42 is corresponding with the cross-sectional area of the narrower cylindrical part 46 of piston 44.

In one embodiment, gasket seal 48 is arranged on the exterior cylindrical surfaces of two cylindrical parts 45,46.In this example, gasket seal 48 is for being arranged in the O-ring seals in circumferential groove 49.

When the lower and narrower cylindrical part 46 of piston 44 during through lower and narrower chamber 42, two chambers 41 of

cavity

40 and 42 directly do not communicate with each other.On the contrary, when low cylindrical part 46 promotes while leaving chamber 42, two

chambers

41 and 42 fluids are communicated with and under uniform pressure.Fig. 3 B shows the piston 44 in raised position, and wherein,

chamber

41 and 42 communicates with each other.

In the illustrative embodiments of Fig. 2, Fig. 3 A and Fig. 3 B, be arranged in the lower part of pneumatic actuator 31 for the supercharged air system 50 that supercharged air is supplied to cavity 40 and it is left from cavity.Air supply system 50 comprises control cock 51, preferably, is two-way valve or triple valve, and this control cock is connected to the source 32 of supercharged air or equivalent supercharging power fluid, is supplied to the pressure of the fluid of cavity 40 for adjusting.Valve 51 is activated by the control unit (not shown) of the operation for controlling whole up-coiler.Valve 51 is associated with pneumatic actuator 31.In Fig. 3 A and Fig. 3 B, same reference numerals 51 is used in reference to for adaptor union, and this adaptor union is for can be at valve 51(Fig. 2) with pneumatic actuator 31 between set up fluid and be communicated with.Housing 39 is formed for being connected to the seat section of valve 51 and bifurcated passage, and this bifurcated passage is for being communicated with between each of valve 51 and two

chambers

41,42, setting up fluid.Common conduit 52 bifurcateds that are communicated with valve 51 become two independent pipelines 56,57.The first pipeline 57 is connected common conduit 52 with wider chamber 41.Second pipe 56 is connected common conduit 52 with narrower chamber 42.Two

independent pipelines

57 and 56 are supplied two

chambers

41 and 42 individually.

According to an embodiment, all

pipelines

52,56,57 all are formed in the housing 39 of pneumatic actuator 31.

According to an embodiment, for two

independent pipelines

56 and 57 of supply and emptying two

chambers

41 and 42, be provided with at two pipelines, 56,57 mobile fluids, causing different loss of pressures or pressure drop.Valve 51 is preferably by second nozzle (choked nozzle) the 53 supply common conduit 52 of being jammed, and this second nozzle that is jammed produces set pressure loss in common conduit 52 and pipeline 56.

As shown in Fig. 3 A-Fig. 3 B, the first pipeline 57 is provided with first nozzle 59 that is jammed, and this first nozzle that is jammed produces predetermined pressure drop in pipeline 57.Be jammed pressure drop that nozzle 59 causes significantly higher than by the second definite pressure drop of nozzle 53 of being jammed by first.

In the illustrative embodiments of Fig. 3 A, Fig. 3 B, first nozzle 59 that is jammed is arranged in pipeline 57, and at its installed position, this pipeline is in wider chamber 41 upper sheds on top.

The operation of package retainer arm can be as following.In the normal winding process, arm 14 slowly raises due to the increase of package.Piston 44 is upwards pulled by ball-and-socket type joint 34.Control cock 51 can be distributed supercharged air under controlled pressure, with for carrying out balance with respect to cylinder 13 and regulating the contact of package 12.Fluid stream is little.Second nozzle 53 and first nozzle 59 that is jammed that is jammed does not apply any obvious effect.

In the time must promoting package retainer arm 14, by the control signal from the up-coiler control unit, open valve 51.The valve 51 of opening can obtain pressure with maximum pressurized liquid is supplied in cavity 40, thereby jigger lifting piston 44(Fig. 3 is B).

When package retainer arm 14, when reducing, for example, make new pipe 29 be shelved on while driving on cylinder 13 against ground, valve 51 is opened by the control signal from the up-coiler control unit.Valve is opened discharge the pressure in actuator 31 and make fluid leave chamber 41 and 42.Due to himself weight, package retainer arm 14 descends.When down stroke starts, piston 44 is in the position shown in Fig. 3 B.Be calibrated to and cause that in pipeline 57 first of the high loss of pressure nozzle 59 that is jammed does not hinder discharge stream, because pipeline 56 is communicated with all internal capacities of cavity 40.Therefore, in the starting stage descended, package retainer arm falls relatively soon.Then, as shown in Fig. 3 A, when piston 44 reduces to such an extent that be enough to introduce in lower chambers 42 by its low cylindrical part 46, two

chambers

41 and 42 no longer directly are communicated with.First nozzle 59 that is jammed prevents that the fluid be included in chamber 41 from flowing out fast.Therefore, in the decline that piston 44 and arm 14 descend at piston 44, slowly reduce.Chamber 41, therefore as energy disperser (shock absorber, vibration absorber), suddenly impacts in package to prevent package retainer arm.Therefore, prevent driving cylinder 13 and for the damage of the pipe that keeps bow member.

Second is jammed aspect nozzle 53 slows down in the first of the decline that makes piston 44 and arm 14 is favourable.In fact, too quick if arm descends in the first of its decline, once the narrower cylindrical part 46 of piston enters narrower cylindrical chamber 42 so, arm will upwards recoil.

As the second be jammed the substituting of nozzle 53, pipeline 52 or pipeline 56 can be made into very narrow, thereby in the situation that do not provide second nozzle 53 that is jammed to form predetermined pressure drop.In so replaceable embodiment,

identical pipeline

52 or 56 will be with the device that acts on the fluid of convection current through them and form significant loss of pressure or pressure drop.

Experimental test illustrates, at (the brake that slows down, stopping) the decline aspect of package retainer arm has good result, this can realize by following embodiment: the cross-sectional area that makes narrower chamber 42 is in the scope of 6%-15% of area of wider chamber 41, and the length of the narrower cylindrical part 46 of piston 44 is in the scope of 10mm-30mm.This length is corresponding with the decline of the down stroke of piston 44, and this decline was slowed down or stopped before package retainer arm arrives its lay-down position.Preferably, in order to obtain buffering (absorption of vibrations) effect, cause first of larger loss of pressure to be jammed diameter that nozzle 59 has at about 0.1mm to the scope of about 0.5mm.Above-mentioned size should not be considered to restrictive value.

For example, in the up-coiler of manual type, the controller for lifting and reduction package retainer arm 14 with actuator 31 can comprise the switch be positioned on the assembly 27 activated by the operator.Use is equipped with the up-coiler of the automatic mode of doffing cart, and when this car arrives wait the coiler of serving, actuator 31 can be by Long-distance Control.Therefore the lifting of package retainer arm and reduction carry out any operation without the operator of manual coiling machine, also do not need between car and sutomatic winding machine to have any physical contact.

Fig. 4 A and Fig. 4 B show a replaceable embodiment of air cylinder actuator 31, and this air cylinder actuator can be provided with additional device 65, in the situation that work as yarn adapter 6, waiting to activate the package that raises.Fig. 4 A and Fig. 4 B show respectively the operating conditions of actuator 31 in the coiling of yarn 2 and engaging process.

As narrated, package retainer arm must promote with for engaging yarn.For allowing this purpose, at first package must raise, stop, and after yarn engages, is shelved on backward on the driving cylinder.In these cases, only several millimeters are just enough in the top, position, angle that lifting package retainer arm and rising piston 44 arrive because package increases gradually over arm 14.

As shown in Fig. 4 A, package retainer arm 14 is in its control position.Valve 51 is opened, and brings into play it and arm is carried out to the function of counterweight.In this example, additional device 65 is mounted to the upper part of actuator 31, is positioned on housing 39 outsides.Additional device 65 comprises the second ring-type cylindrical chamber 70, and this ring-type cylindrical chamber is internally limited by housing 39 and externally limited by the second cylindrical housings 73.In this embodiment, the top of annular compartment 70 is sealed with top cover 74.Annular compartment 70 interior slips be piston 71, this piston has annular shape and the size of coordinating with chamber 70.Preferably, annular piston 71 have for example be provided with the liner 78(that is arranged on by force in circumferential groove 79, O-ring seals) cylindrical surface.Because the promoting required stroke for so-called moment and be limited to several millimeter of piston 44, so the required height of chamber 70 can be greater than the height of annular piston 71 slightly.

According to an embodiment, for supercharged air being supplied to annular compartment 70 and making supercharged air be arranged in the downside of annular piston 71 from the supercharged air open/close system 80 wherein left.In this illustrative embodiments, air supply system 80 comprises the triple valve 81 in the source 82 that is connected to supercharged air or equivalent compress fluid.In the time must engaging yarn, by up-coiler control unit (not shown) activated valve 81.81 pairs of pipelines of opening on the bottom of annular compartment 70 83 of valve are supplied.Advantageously, pressurized air source 82 can be with to be arranged on up-coiler the pressurized air source 32 for other services consistent.

In the embodiment of Fig. 4 A and Fig. 4 B, on the top of the inside face of annular piston 71, be formed with conical surface 85.At the upper end of cylindrical housings 39, in the free space limited, be furnished with a plurality of spheroids 86 between piston 44 and conical surface 85.The size of the diameter of spheroid 86 just is less than the size of free space.

When the bottom surface that allows supercharged air against annular piston 71 enters annular compartment 70 so that while opening valve 81, piston 71 promotes.Conical surface 85 makes them press piston 44 spheroid 86 locking, thus clamp piston 44 and it is upwards dragged, until its butt lean on top cover 74 tightly.

In one embodiment, between the upper surface of annular piston 71 and top cover 74, a plurality of opposition springs (being not shown in the drawing for the sake of simplicity) are installed.These springs load by the rising of piston 71.When the controlled unlatching of valve 81, in order to discharge while being present in the pressure in annular compartment 70, the thrust of opposition spring occupies leading and annular piston 71 declines, thereby spheroid 86 is descended and release piston 44.Therefore, piston 44 is got back to its residing previous height before additional device 65 activates, thereby allow package again to be shelved on, drives on cylinder 13.

With respect to prior art systems, the utility model provides significant advantage, in these advantages, should at least mention following.The control of package retainer arm and always activating is carried out by single supercharged air actuator (that is, for applying the configuration effect), for fully arm being promoted, and for making arm moment promote to engage yarn.The decline that the motion of arm makes it move downward slows down, thereby slows down contacting between pipe or initial package and driving cylinder.For the doffing cart of operator or auto reeling device, be no longer necessary for and carried out doffing operation and make package retainer arm promote fully.In the beginning of step of doffing, because the control signal of the control unit of up-coiler promotes arm, thereby contribute to operator's work or simplify doffing cart, because arm raises.

According to a different embodiment (not shown), actuator can have the reverse arrangement with respect to the embodiment shown in Fig. 3 A-Fig. 3 B and Fig. 4 A-Fig. 4 B.According to such replacement, the place, top that the narrower cylindrical part 46 of narrower chamber 42 and corresponding piston can be in actuator, that is, and near arm 14.Correspondingly, supply system 50 also will need upset, as Fig. 3 A and Fig. 3 B, turn upside down.
