Abstract

A winding machine is disclosed for winding yarn on a tube to form a package. A package holder arm is pivotally mounted to a fixed structure of the winding machine for rotation about a pivot. A pneumatic actuator causes the package holder arm to be raised or lowered, rotating about the pivot. The actuator has a cavity with two cylindrical chambers of different diameters and a correspondingly shaped piston. The pneumatic actuator is associated with a pressurized air supplying system comprising a control valve. The valve separately supplies and discharges the first, wider cylindrical chamber (41) and the second, narrower cylindrical chamber chamber through two separate first and second conduits. The first conduit, communicating with the wider chamber comprises a choked nozzle for causing a first loss of pressure in the fluid flowing through the first conduit. This first loss off pressure is greater than a second loss of pressure which takes place in the fluid flowing through the second conduit, which communicates with the narrower cylindrical chamber.

The specific embodiment

Fig. 1 shows the front elevation of the main portion of up-coiler (or coiler).Make charging bobbin unwinding by the yarn 2 that picks up charging bobbin 1.Yarn 2 passes from the unwinding unit 3 that comprises balloon breaker, seal wire member 3, yarn detector 4 and yarn tensioner 5.This can comprise for example adjustable deflector (deviator), and this deflector can be so that be used for the more crooked tension force with adjuster in path of yarn.What be in tensioner 5 downstreams is adapter 6, needs the end of the interruption yarn of joint to be picked up to adapter by

suction nozzle

9 and 10, and this suction nozzle lays respectively on the sidepiece of charging bobbin and package.Show the high workload position of suction nozzle with 9 ' and the 10 ' imaginary line of locating.In those positions, suction nozzle 9 will be positioned at yarn end on the charging bobbin side and pick up to adapter 6 and suction nozzle 10 and pick up the yarn end from package.When the yarn clearer 11 that is positioned at adapter 6 downstreams when yarn interrupts or gets involved and interrupts, suction nozzle work.Yarn is collected in the package 12.Package is shelved on by driving rotation on the driving cylinder of package retainer arm 14 supports or the roller 13 and by it.

Usually, the distribution of yarn 2 in package 12 carried out by lateral guides (traversing guide), thereby forms the package with given coiling ratio.In the diagram of Fig. 1, the distribution of yarn in package carried out by identical driving cylinder 13.This cylinder is provided with transverse slot 17, and this slit drives the required driving torque of cylinder 13 transmission winding yarns simultaneously so that yarn 2 has the lip-deep reciprocal axial motion in package 12.Being formed on the number that drives the spiral transverse slot on the cylinder 13 changes according to counting and the coiling compactedness of package to be formed.

In its course of normal operation, each up-coiler all uses a large amount of charging bobbins to form the much bigger package of size.Usually, charging bobbin unwinding within a few minutes is wrapped in simultaneously in one hour and finishes.The place is furnished with usually be used to the system that moves forward into the stockline axle in the bottom of coiler, and it is to the new bobbin charging for the treatment of unwinding and remove the pipe (tube) of completed bobbin, even mobile several thousand bobbins per hour.On the top of coiler, per hour form a large amount of packages.Must remove package and with the new pipe in the package retainer arm it is replaced, all again start up-coiler at every turn.Utilizing sutomatic winding machine, can be that such coiler that utilizes other types is carried out in required each operation and movement by the doffing cart that is equipped with special device, and these operations are manually carried out by operating personal.

Fig. 2 shows the lateral plan of the structure of the package retainer arm 14 of carrying out mobile and several functions.

The cross sectional drawing that Fig. 2 shows package retainer arm 14 as sees from the left side.As shown in Figure 1, arm 14 can have the U-shaped structure, and this structure forms two protrusions (prong), supports two bow members (center) at

end

22,23 places of these two protrusions.The right hand end movable support bow member 26 of protrusion 23, it has the device 27 that can open and close to discharge package or receive the new pipe 29 that is used for package 12.The end portion supports of protrusion 22 is bow member 25 fixedly.Package retainer arm 14 can raise and reduce, along the circular arc that is defined by two stop parts (for simplicity, and not shown) and around pin 28 rotations.

The opening and closing campaign of movable bow member is mechanically carried out by opening mechanism usually, and this opening mechanism opposes by the spring that tends to close bow member.

Package retainer arm places on the fixed sturcture 30 of up-coiler by actuator 31.For instance, the air cylinder that is provided by pressurized air source 32 can be provided actuator 31, and this air cylinder allows rising and the reduction of control package retainer arm.Actuator 31 has two ends, and in these two ends, the bottom is connected to fixed sturcture 30 and the upper end is connected in two

protrusions

22,23 of package retainer arm.The end of actuator is provided with ball-and-socket type joint, to allow air cylinder owing to arm 14 rotates around the rotation of pivot 28.

In the winding process process, package retainer arm increases owing to package and is raise by package.For example according to the patent publications EP1820764 with the applicant's name, by actuator 31, can apply counterweight forces to arm, thereby regulate package 12 at the contact that drives on the cylinder 13, so that the density of the package in determining to form.

When coiling stops so that when yarn engaged or fall, package must raise, brakes and stop.For this purpose, package retainer arm is provided with the drg that is activated by pneumatic piston (also not shown for simplicity).

When the beginning package, the bow member of retainer arm must be opened, and provides the new pipe of yarn to be spooled on it.When bow member after new pipe is closed, package retainer arm reduces so that new pipe contacts with driving cylinder 13, thereby draws yarn and begin new package 12 from charging bobbin 1.

In case finish package, bow member that then must be by opening package retainer arm with its rising, brake and remove.Then new pipe is installed on the arm to be used for accepting coiling.This operation is known as at present doffs.This can manually be carried out by the operator, and perhaps in the situation that the auto reeling device is carried out by work car, this work car marches to the position of up-coiler with execution work.Before beginning to doff step and stopping package, retainer arm as far as possible highland raises, and so that package 12 is risen to cylinder more than 13, thereby leaves large quantity space for doffing operation.

Usually, reel, engage and the process of doffing in, the above-mentioned motion of package retainer arm and function are by by the control unit control of up-coiler and a plurality of devices execution that cooperate with doffing cart.

By several preferred shown in Fig. 3 to Fig. 4 but the explanation of non-limiting embodiment is more obvious according to characteristic and the advantage of package retainer arm of the present invention.

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 invention.In Fig. 3 B, actuator is than extending in Fig. 3 A or raising manyly.As shown in Fig. 2, actuator 31 can comprise the housing 39 that limits slip cavity 40 as equally, 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 slidingly received in the 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 corresponding to

chamber

41,42 diameter, is the configuration of mushroom-shaped thereby limit totally.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 installed on two

cylindrical parts

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

When the lower and narrower cylindrical part 46 of piston 44 passes lower and during 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 when leaving chamber 42, two

chambers

41 and 42 fluids are communicated with and are under the uniform pressure.Fig. 3 B shows the piston 44 that is in the 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 used for supercharged air being supplied to cavity 40 and making its supercharged air system 50 of from cavity, leaving be arranged in the lower part of pneumatic actuator 31.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 used for regulating the pressure of the fluid that is supplied to cavity 40.Valve 51 is activated by the control unit (not shown) for the operation of 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 used 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, this bifurcated passage be used for valve 51 and two

chambers

41,42 each between set up fluid and be communicated with.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, be used for supply and emptying two chambers 41 and be provided with for causing different loss of pressures or pressure drop at two

pipelines

56,57 fluids that flow with two of 42 independent pipelines 56 and 57.Preferably by the nozzle that is jammed (choked nozzle) 53 supply common conduit 52, this nozzle that is jammed produces the set pressure loss to valve 51 in common conduit 52 and pipeline 56.

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

In the illustrative embodiments of Fig. 3 A, Fig. 3 B, the nozzle 59 that is jammed is installed in the 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 owing to the increase of package.Piston 44 is by upwards pulling of ball-and-socket type joint 34.Control cock 51 can be distributed supercharged air under controlled pressure, to be used for coming balance and regulating the contact of package 12 with respect to cylinder 13.Flow is little.The

nozzle

53 and 59 that is jammed does not apply any obvious effect.

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

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

chambers

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

Be jammed nozzle 53 so that the first of the decline of piston 44 and arm 14 slow down aspect be favourable.In fact, too quick if arm descends in the first of its decline, in case the narrower cylindrical part 46 of piston enters narrower cylindrical chamber 42 so, then arm will upwards recoil.

As substituting of the nozzle 53 that is jammed, pipeline 52 or pipeline 56 can be made into very narrow, thereby in the situation that do not provide the 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 before package retainer arm arrives its lay-down position or stopped.Preferably, in order to obtain buffering (absorption of vibrations) effect, cause diameter that the nozzle 59 of larger loss of pressure 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 that is used for lifting and reduction package retainer arm 14 with actuator 31 can comprise the switch that is positioned on the assembly 27 that is activated by the operator.Use is equipped with the up-coiler of the automatic mode of doffing cart, and when this car arrived coiler to be served, actuator 31 can be by Long-distance Control.The operator that therefore lifting of package retainer arm and reduction need not the manual coiling machine carries out any operation, does not also need to have any physical contact between car and the sutomatic winding machine.

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, are used for waiting to activate the package that raises in the situation that work as yarn adapter 6.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 narrating, package retainer arm must promote to be used for engaging yarn.For allowing this purpose, package must at first raise, stop, and is shelved on backward after yarn engages on the driving cylinder.In these cases, promote package retainer arm and rising piston 44 surpass top, position, angle that arm 14 arrives owing to package increases gradually only several millimeters just enough.

As shown in Fig. 4 A, package retainer arm 14 is in its control position.Valve 51 is opened, and brings into play it carries out counterweight to arm function.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 installed in by force in the circumferential groove 79, O-ring seals) cylindrical surface.Because the so-called moment that is used for of piston 44 promotes required stroke and is limited to several millimeters, thus the required height of chamber 70 can be slightly greater than the height of annular piston 71.

According to an embodiment, be used 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 that wherein leaves.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 83 of opening in the bottom of annular compartment 70 of valve are supplied.Advantageously, pressurized air source 82 can be with to be arranged on the up-coiler pressurized air source 32 that is used for other services consistent.

In the embodiment of Fig. 4 A and Fig. 4 B, be formed with conical surface 85 at the top of the inside face of annular piston 71.At the upper end of cylindrical housings 39, in the free space that between piston 44 and conical surface 85, limits, be furnished with a plurality of spheroids 86.The size of the diameter of spheroid 86 is just 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 when opening valve 81, piston 71 promotes.Conical surface 85 with spheroid 86 locking so that they press piston 44, thereby clamp piston 44 and it is upwards dragged, until its butt and 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.So that discharging is when being present in pressure annular compartment 70 in, the thrust of opposition spring occupies leading and annular piston 71 descends, thereby makes spheroid 86 decline and release piston 44 when valve 81 controlled unlatchings.Therefore, piston 44 is got back to its residing previous height before additional device 65 activates, and drives on the cylinder 13 thereby allow package again to be shelved on.

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

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