Description
Technical field
The present invention relates to a kind of being used in fiberline at the method for the Texturized back guiding of tow filling (case) tow and the device of implementing this method.
Background technology
Known when making staple fibre, tow is processed in fiberline and is handled, so that terminal by a cut-out device cut-out at fiberline.In order staple fibre to be had be similar to the structure of natural fabric, tow is Texturized by means of a Texturized device before cutting off.Texturized by means of a Texturized device generation by the work of so-called stuffer box principle.Tow is by the roll gap guiding between the Texturized roller of two rotation drivings for this reason.Connect a stuffer box on the prolongation silk of roll gap, it is set directly at Texturized roller back, and reception and the Texturized tow of continuation guiding.The tow waveform is crooked and leave Texturized device with a Texturized speed, the conveyer belt that is set at the back until tow receives, and before cutting off, flow to drying device, here conveyer belt drives with identical with Texturized speed basically belt speed, so that Texturized tow is imported drying device continuously.
Because the strong mechanical stress of tow is also known during filling (case) is Texturized, the processing that added on tow before cutting off especially oils.Handle and directly before tow enters drying device, carry out.Because be used for to the conveyer belt of drying device charging reciprocatingly, therefore need complicated treating apparatus at the outlet side of conveyer belt.Tow enters in the drying device from conveyer belt by dropping in addition, thereby forms the speed that depends on quality in the tow during additional treatments, is difficult to avoid scrambling thus.
Summary of the invention
The objective of the invention is, improve being used in fiberline the method and apparatus of guiding tow behind stuffer box crimping in this wise, make the additional treatments that before tow drying behind the stuffer box crimping, can carry out possibly.
Another object of the present invention is to reach by conveyer belt and export tow equably, so that obtain uniform tow stacking in drying device.
Realize by method with claim 1 feature and device by this purpose of the present invention with claim 12 feature.
The present invention is special, and advantage is, reaches very even in its quality and aspect of performance by the tow of conveyer belt output in the time per unit on the one hand, and tow is advantageously distributed in drying device; Tow experiences a state that additional treatments is simplified greatly before entering drying device on the other hand.For this reason by forming a processing section by method of the present invention, tow is extracted out with belt speed in this section, the belt speed of conveyer belt and tow are adjusted in this wise in order to the ratio of the Texturized speed of leaving Texturized device for this reason, make tow at first in Texturized section waveform advance, after then unclamping (Aufloesung) in waveform then, be converted in the processing section.Therefore form a zone between Texturized device and conveyer belt, tow is transformed into releasing orientation by waveform in this zone.This releasing orientation of tow depends on the tension that is produced by conveyer belt when waveform is unclamped.
Directly do not pull out from Texturized device for fear of tow, the present invention is by the improvement structure advantageous particularly of claim 2 with not allowing, and the belt speed of conveyer belt is adjusted to and makes Texturized section to keep certain length here.Texturized section length is determined by the ratio of Texturized speed and belt speed basically.Adjusting by belt speed can make the ratio of Texturized speed and belt speed remain unchanged, and therefore, Texturized section length also remains unchanged basically.
Here can advantageously directly or indirectly measure Texturized segment length in order to regulate belt speed, so that can carry out the adjustment of belt speed according to the variation of length.
Therefore belt speed just raises when surpassing maximum length for Texturized section, thereby produces big tension in the release point of tow, and causes Texturized section shortening.Belt speed advantageously reduces when being lower than minimum length for Texturized section, makes to cause less pulling force on the released position, and this directly causes Texturized section lengthening.
When the length of directly measuring Texturized section, directly monitor the released position of tow.For owing to only there is the situation of little difference between the waveform of the less tow of tension and the stretching shape, preferably adopt the indirect coupling of Texturized segment length.This scheme by claim 5 is proved particularly advantageous.Measure the tow component of in Texturized section stub area, advancing by weight for this reason, and constantly and corresponding to the theoretical amount weight ratio of Texturized section theoretical length.
Weight measurement can advantageously be carried out by means of a balancing pole (Wippe), and this balancing pole is laid the component of tow on an arm, has the theoretical weight of theoretical section on a relative arm.
For the too short situation of Texturized segment length, the arm with balancing pole of theoretical weight tilts with respect to the arm with tow component very little.This moves through a sensor measurement, and flows to an adjusting device as sensor signal, correspondingly is transformed into the control signal that is used for changing the conveyer drive unit at adjusting device inner sensor signal.Therefore the conveyer drive unit is adjusted to less belt speed in this case, makes Texturized section length strengthen, thereby the component of depositing on the arm of balancing pole is strengthened.Therefore the balancing pole balance no longer produces other signals that are used for changing belt speed as a result.
Therefore reach constant basically processing section length by regulating belt speed.In order to handle the tow in the processing section, tow advantageously level is advanced.
In order in processing section, on tow, to oil this orientation advantageous particularly of tow.At this moment tow passes oiling device with belt speed.This improvement structure has special advantage, and promptly drying send band can not take place directly to contact with oil agent.Such problem appears in the outlet side of conveyer belt in the known structure of oiling device, and promptly Di Luo oil agent falls on the conveyer belt of drying, and must remove in dry run.This improvement structure has been avoided this problem.Can avoid moving-mass in addition thus at the outlet side of conveyer belt.
For the belt speed of shutting down the back at fiberline or after fiber speed changes, obtaining being complementary with Texturized speed; according to a kind of particularly advantageous scheme proposals, measure Texturized speed and before for example fiber production linear velocity stops or improving, carry out Texturized speed at that time actual value and the comparison between the theoretical value adjusted in advance.After comparison, can correspondingly adjust belt speed.
The present invention is equally by the feature of the device of claim 12: can carry out a possible processing between Texturized device and conveyer belt.Between Texturized device and conveyer belt, form Texturized section and one a processing section that is used for guiding tow that is used for receiving the waveform tow with belt speed with Texturized speed for this reason.Here Texturized section length can be by the driving device controls of conveyer belt, and wherein tow is pulled out by conveyer belt in processing section.
Has a measurement mechanism that is used for measuring Texturized segment length in order to regulate belt speed by device of the present invention.Measurement mechanism is equipped on the adjusting device that is connected with feed drive device that is used for regulating belt speed.For the length-measuring appliance of directly determining Texturized section is preferably done to such an extent that be with a sensor, can measure stretching position at Texturized section end tow by this sensor.But also can adopt a plurality of sensors, so that for example observe Texturized section length in borderline region with minimum length and maximum length.
For the indirect length of measuring Texturized section, a kind of like this improvement structure of apparatus of the present invention proves particularly advantageous, adopts a balancing pole and at least one to be used for measuring the sensor of balancing pole motion in this improvement structure.Wherein on the one arm of balancing pole, lay a theoretical weight.The in addition one arm that balancing pole is relative is used for being placed in the component of the waveform tow of Texturized section end, therefore is equipped on the outlet of Texturized device.
In order to carry out simple 2 adjustings of belt speed, every arm of balancing pole sets a sensor respectively.The sensor that is equipped on the arm with theoretical weight can correspondingly send signal when belt speed reduces, the sensor that is equipped on the arm with tow component can send signal when belt speed raises.
For the definite lay that obtains installing the tow that the balancing pole waveform advances from Texturized, Texturized device sets a guide plate, and it is equipped on the floating bearing of balancing pole with its free end.
In order to compensate the oil agent loss that causes during Texturized, a kind of like this improvement structure advantageous particularly of apparatus of the present invention, an oiling device is arranged in the processing section and curls between deformation section and the conveyer belt in this improvement structure.For the work of the tow that oils by conveyer belt passes oiling device in order to belt speed.Therefore reach the uniformity that oil agent on the tow is coated with floor height by regulating belt speed.
Oil agent is preferably by once nozzle and top nozzle are sprayed on the tow.During whole service, obtain evenly smearing of oil agent by regulating belt speed.
