Description

Textile maschine having yarn accumulator

The present invention relates to process the weaving loom that multifilament yarn is used, wherein: by a Yarn supply system this multifilament yarn is sent into a treatment region, and its unwinding from treatment region is gone out through a unwinding system; And a yarn storage device that is located at this Yarn supply system downstream is arranged, be used for when sending to of yarn in the process broken yarn or other inhomogeneity takes place, making yarn do provisional storage.

The weaving loom of the above-mentioned type, for example the sort of described in the DE-OS2254736 patent belongs to known equipment.In this kind weaving loom with yarn from it production or the processing district unwinding when going out, often must the speed when one is sent to this kind district than it be to carry out under the high speed.For a kind of like this mode that makes yarn output, in defeated yarn process inhomogeneity takes place with regard to regular meeting.This class inhomogeneity both may since the production method of yarn itself caused, also may since this production process continue after operation in interference takes place causes.This class inhomogeneity in the defeated yarn is easy to cause fault in the course of processing, for example make the yarn kink or around volume.Yarn for the operation of weaving loom significant impact is arranged around the volume problem because this kind can damage weaving loom itself around the volume phenomenon.Even when having only the inhomogeneity of short time in the defeated yarn process, also might form yarn around volume, thisly for example can be created in batching in the district of weaving loom, particularly can occur in the yarn that must will send to continuously when completely package is transferred on the blank pipe around the volume phenomenon.

The known equipment of above-mentioned this class also has such shortcoming: it need use enough strong compressed air source, and when fault takes place or must turn round continuously, or must shut down.When this was in the operational process at equipment, the problem of being mentioned above wanting to avoid may be late.

Another shortcoming is, recognized already, when fracture of wire betides the downstream of Yarn supply system, the loose thread in falling may twist together or circumvolution in other Yarn supply system, perhaps also may after-combustion to other rotatable parts processing station or adjacent processing station of these yarns.In the worst case, the loose thread that falls even can damage the parts of weaving loom.At last, remove the resistates of this kind yarn after being difficult in.

For this reason, one of purpose of the present invention is to provide a kind of equipment can be used for temporary transient the storage because of a certain amount of yarn that yarn is lax in the Yarn supply system downstream or fracture occurs, and this kind storage yarn equipment can at any time put into operation immediately, and the while does not need auxiliary device.

Another object of the present invention is to a kind of like this yarn storage device of providing above-mentioned, it can be used to collect loose thread and makes it not reconstruct harm when broken yarn takes place.

Above-mentioned purpose and the advantage with other of the present invention is accomplished in can illustrated below embodiment, a multifilament yarn Fabricating machinery is provided in this embodiment, this equipment includes: yarn feeding device is used for making this kind yarn to advance to a treatment region along an effective transfer passage; And yarn storage device, it is positioned at the nearest downstream of above-mentioned yarn feeding device, and includes the deflecting plate that possesses two relative sides.This plate roughly above-mentioned effective conveying of crosscut yarn effectively transfer passage is adjacent therewith all and with one of its relative side.Like this, when yarn when its effective transfer passage is advanced, can not be subjected to this project and ring and significantly turn to.But when broken yarn or similar phenomenon took place, the yarn in advancing plate therewith engaged.

Yarn feeding device limits the defeated yarn channel of a nature, along this passage, yarn can be fed to the downstream of this yarn feeding device under the condition that lacks guidance device, with on deflecting plate engages, then preferably get and can fail the crossing position of yarn channel naturally with this by this plate when broken yarn or analogue take place for yarn in simultaneously guaranteeing to carry.

Yarn storage device preferably also is provided with a thread-carrier on that side of effective transfer passage of the yarn relative with the said side of above-mentioned plate, and makes this effective transfer passage between said side of above-mentioned plate and thread-carrier.

According to the present invention, this deflecting plate is urged to have caused yarn in batch and is stored in harmless position, and because this kind event memory, so large quantities of yarn just can not occur with single form again.Single yarn is subject to unavoidable air flow effects and is caught by other machine part, but the storage of the yarn of formation totally then can maintain yarn like this, and is difficult for being subjected to airflow influence owing to it has big quality.

Using does not generally need the textiles processing machine device is done any change when of the present invention.If but make the unwinding of yarn or the relative Yarn supply system skew of withdrawing device, and make this take-off device not when the defeated naturally yarn channel of this Yarn supply system extends, may benefit.This defeated naturally yarn channel generally is tangent with Yarn supply system, or is on the common tangent of driven yarn feeding roller and pressure roll in so-called pressure roll shape Yarn supply system.Even but do not do such change, above-mentioned deflecting plate also is an actv., because this deflecting plate often is can be configured in the direct neighbor district of above-mentioned effective passage, perhaps even if this deflecting plate is when being among this effective passage, under normal defeated yarn situation, this passage also is that extraction system by Yarn supply system and yarn has pre-determined.

Stated some purpose of the present invention and advantage above already, other purpose and advantage will be reflected in the description of carrying out below in conjunction with accompanying drawing, in the accompanying drawings:

The embodiment that describes below has illustrated the present invention who combines with the false twisting weaving loom of the yarn that is used for processing the synthetic multi-filament yarn yarn.But it should be understood that the present invention also can be used for including other textiles processing machine that is used for carrying along effective transfer passage of yarn the yarn feeding device of yarn.

As Fig. 1 and this kind weaving loom that shows illustrated in Figure 3, include the confession yarn package 10 that is wound with themoplasticity multifilament yarn 12 above.Yarn 12 is to go out via a thread-carrier 14 unwindings by Yarn supply system 18 under certain tension force.Send in the yarn direction at such one, be extended with one first elongated temperature booster 20 in the downstream of this Yarn supply system 18, yarn 12 is promptly advanced above it and is heated to a predetermined temperature by it.Exit end at temperature booster 20 is provided with a guide roll 22 in addition, and it turns to yarn and is transported to a cold plates 24.This temperature booster 20 can relatively be configured to approximate a kind of roof configuration mutually with cold plates 24, and is formed the ridge of this roof structure by above-mentioned guide roll 22.The below of cold plates 24 is common false-twisting devices that show in the signal of 28 places, and it for example can constitute for No. 4339915 according to No. 2213881, Deutsche Reichspatent or US Patent.Be provided with another Yarn supply system 30 in the downstream of false-twisting device 28, be used for the yarn drawing is crossed both tops of temperature booster 20 and cold plates 24.

Send in the yarn direction above-mentioned, be provided with a kind of combination heater under Yarn supply system 30, it is made of the bending heating pipe 34 that a heating jacket 32 is centered on.Heating jacket 32 usefulness cause steams are from these heating pipe 34 to one predetermined temperatures of external heat.Best, heating pipe 34 and overlap 32 and get vertical installation form.

Heating pipe 34 connects with seamless way that is is connected on the equalizing pipe 42 with air tight manner.Thread-carrier 44 is arranged in the sweep of a passage 38 that is connecting heating pipe 34 and equalizing pipe 42, and has the pin or the roller shape structure of band circumferential groove.

The exit end place of pipe 42 is provided with another Yarn supply system 46.This Yarn supply system is the Yarn supply system of a pressure roll shape, comprises a driven yarn feeding roller 46.1 and a pressure roll 46.2, and pressure roll freely rotates and can yarn be pressed on the yarn feeding roller by nonslipping mode.Adjacent with it have a yarn storage device 1, and the back will be described it.Yarn is winding on the coiling package 50, and the periphery of this package is that a friction roller 52 drives.Be provided with a transversing mechanism 54 in the upstream of this friction roller 52, it impels the package of yarn 12 along package 50 crank motions and a kind of cross winding of coiled.Suction pipe 62(Fig. 2 A that one band radial hole is then arranged in the place ahead of this transversing mechanism).When package 50 when full, and when when making this package doff need between suction pipe 62 and transversing mechanism 54 yarn cut off, suction pipe 62 just can be removed yarn by aspirating.

Be provided with a platform 56 above equalizing pipe 42, it is supported on the ground 60 by track or pillar 58, can be used as operative employee's aisle.

Fig. 2 A shows in the enlarged detail that batches the district, particularly Fig. 2 in the regional II among Fig. 1 to understand yarn storage device 1 in more detail, and the latter just can be worked when broken yarn or yarn are lax.

Show brightly for Fig. 2 A-2C knows, yarn storage device 1 comprises a thread-carrier 2 and a deflecting plate 3, and they are installed on the public support 4.Deflecting plate 3 has two opposed side edges 5,6, defines two plate sections 8,9 along a crestal line 7 bending, and the V that they relatively tilt mutually into about 90 ° of angles opens.When along advancing the yarn direction and observe shown in Fig. 2 B, this crestal line 7 is to extend towards the direction of thread-carrier 2.Simultaneously, 2 of thread-carriers are in deflecting plate 3 after a while nearby.

Deflecting plate 3 for example can be made of two flat sheetmetals, and they are joined along crestal line 7; Deflecting plate 3 also can be made of along this kind crestal line jack-knife a flat sheetmetal.

Deflecting plate 3 can have smooth surface, or also desirable infundibulate, and its axis then roughly is to extend in the natural direction that effectively advances of yarn.In addition, turn to power 3 towards a side of Yarn supply system viscous coating to be set at it, so that be detained the loose thread that firmly breaks and, the back will further describe this.This kind viscous coating for example can be the film that a kind of two sides all scribbles cohesive material, and it is applied on the deflecting plate and a cated side of this plate is exposed.In addition, deflecting plate also can be close to band coated with one deck, and the cellulosic adhesive linkage of gib head is arranged above it, generally shows as Fig. 3 A.

Deflecting plate 3 is assembled into the effective transfer passage that is substantially transverse to yarn, and transfer passage is closely adjacent but separate slightly therewith with its side 5.2 of thread-carriers are installed on that relative side of side this transfer passage and deflecting plate 35, when making this transfer passage normal operation like this between side 5 and thread-carrier 2.Thereby in course of normal operation, the yarn in advancing just can not turned to by plate 3.

Thread-carrier 2 is provided with the guide of a yarn from the one hand, this guide effective transfer passage same and yarn is close to.The guiding face of this thread-carrier extends along the extending part of the crestal line 7 that is formed by deflecting plate 3, and the side 5 of plate separates a little therewith.Therefore, just have an interspace between the guide edge of the side 5 of deflecting plate 3 and thread-carrier 2, contactlessly pass through when yarn is advanced under tension force, this is extremely clearly illustrated that in Fig. 1.The guide of thread-carrier 2 is laterally defined by two guide plates, and these two guide plates are covered with the side 5 of deflecting plate 3, has formed the lateral boundaries of the transfer passage of yarn simultaneously.The above-mentioned mounting means that deflecting plate 3 and thread-carrier 2 are got in weaving loom makes the crestal line 7 of this deflecting plate approx perpendicular to the transfer passage of yarn.

In weaving loom shown in Figure 1, yarn is reeled without barrier, thus yarn can along it effective transfer passage and between Yarn supply system 46 and batch up gear, advancing under the suitable tension force.The result is under such service conditions, and yarn storage device just can not work all the time.Shown in Fig. 2 A, when yarn cuts off between suction pipe 62 and transversing mechanism 54, just yarn is pulled into the inside of suction pipe 62 subsequently.In this moment, yarn just significantly reduces at short notice from the speed that Yarn supply system 46 unwindings go out.So will bring excessive yarn kink, form around volume or cause danger such as other fault.This class danger can be prevented by the yarn storage device 1 that is installed in the present invention nearby of Yarn supply system 46 downstreams.

When yarn was no longer advanced under suitable tension force, it just will be at crestal line 7 places of 8,9 of two flat plate section of deflecting plate 3 collision deflecting plate.For this reason, yarn storage device is arranged to and make the common tangent location of deflecting plate along yarn feeding roller 46.1 with the pressure roll 46.2 of Yarn supply system 46.When yarn collision deflecting plate, these yarns just begin to gather.Then, these yarns are just pulled out from heap for suction pipe 62.But the yarn amount that accumulates in this heap changes.Therefore, the present invention then can provide a kind of like this condition under the situation that can not cause any harm, wherein Yarn supply system 46 output is the constant yarn of quantity, but the yarn amount of taking out is then for example because the batching or the irregularity of the course of processing rather than constant of discontinuous.

In the false twist crimping machine shown in Fig. 3 and Fig. 4 and 5, be installed in the downstream that deflecting plate 3 on the common support 4 is positioned at first Yarn supply system 18, this Yarn supply system then makes yarn carry along the direction of temperature booster 20.30 of second Yarn supply systems adjacent with false twist crimping device 28 are as a system that makes the yarn unwinding go out or take out.

Yarn shown in Fig. 3 is among the transfer passage when being in the normal of it or work.Under service conditions bright shown in Fig. 4 and 5, loose thread falls, and Yarn supply system 18 is then supplied with open circuited loose thread continuously.Under such service conditions, such danger might take place, promptly open circuited loose thread can enter in the coiling package 50, and its drive element, particularly friction roller 52 can remain in operation with 54 of yarn transversing gears.The open circuited loose thread of this kind also may be pooled in the adjacent processing station.Above-mentioned contingent these problems can be avoided by yarn storage device 1, and this yarn storage device is located at apart from Yarn supply system 18 exit end nearby.The structure of this yarn storage device is with top described consistent in conjunction with Fig. 2 A-2C.

In the operation, yarn is before its servicesubway of tension force effect lower edge is capable, one side be able to not pass through contiguously between the guide edge of the side 5 of deflecting plate 3 and thread-carrier 2 and with any.But also can make the channel offset of yarn storage device, and yarn is slightly turned on deflecting plate or thread-carrier with respect to yarn.This relates to the tension force and the abrasion problem of yarn.When yarn disconnected, it just no longer was under the tension force effect, and is that Yarn supply system 18 is discharged on the deflecting plate, that is entered between two plane surfaces of deflecting plate 3 in the crestal line 7.For this reason, yarn storage device is arranged such that deflecting plate extends along the two common tangent of the yarn feeding roller of Yarn supply system 18 and pressure roll, or in the crossing position of of deflecting plate being in try to achieve by experiment in advance and the natural delivery channel of yarn, yarn transfers to the downstream of Yarn supply system 18 under the condition of no guidance device in this natural delivery channel.

When touching deflecting plate, yarn just gathers in heaps.In the embodiment of Fig. 4, supposed and disposed a kind of aforesaid viscous coating on the deflecting plate.Because this kind coating has been arranged, this class yarn just can be adhered on this viscous coating, thereby has avoided making other rotatable parts in this class yarn contact weaving loom, or freely drifts about in this machine and carried secretly equivalent risk by air-flow.Need only just can remove the resistates of this class yarn from the deflecting plate this coating of tearing then.When adopting the sort of shown in Fig. 3 A to be close to band, when broken yarn and yarn material taking place already aggregation is in heaps already, need only get final product from the deflecting plate this band of tearing.

In the embodiment shown in fig. 5, on the deflecting plate 3 not coated with viscous coating.So a collection of yarn that accumulates just will fall from deflecting plate with the knot form.But have one at this deflecting plate and preserve case 26, it is in a position that is gathered up the knot that this class gathers.

The natural transfer passage of above-mentioned yarn is being meant in theory under the meaning of the present invention that yarn is leaving the tangent line on this point of Yarn supply system, or when Yarn supply system be the common tangent that then is meant when belonging to the jaw type or adopting roll on the respective point.But be can be devious actually, for example in the Yarn supply system that has adopted roll, being attached to a yarn amount on the roller can be more than the yarn amount that is attached on another roller.When yarn is not having along continuous straight runs under the tension force action condition " sputter " when going out, also might cause a deviation.Therefore, having under the condition of query, must measure the natural transfer passage of yarn by experiment in no tension force or low-tension effect following time.In some cases, also need consider the speed of Yarn supply system.

In above accompanying drawing and explanation, set forth a most preferred embodiment of the present invention, although wherein used some concret mouns, these nouns only are to use under common and descriptive meaning, and are not to be used to limit purpose.
