Description
Technical field
The present invention relates to a kind of for melt-spun and the cooling method of many synthetic threads and a kind of device for implementing the method.
Background technology
Congenic method and same device are such as open by WO 2005/052224 A1.
In the manufacture of synthetic thread, usually need to manufacture a large amount of synthetic thread.In order to especially process start with process interrupt during operate, silk thread with group form by multiple exist side by side in spinning equipment arrange spinning station be extruded and cool.The silk thread produced by spinning station is jointly by configuring to the coiler device wound into rolls at this spinning station.According to the feature of coiler device, 8 to 32 silk threads can be produced in a spinning station simultaneously.Exist side by side and run and be jointly based upon in a workshop in spinning station.In order to cool the silk thread just extruded in spinning station, for each spinning station inputs independent cooling-air stream, this cooling-air stream is input to relevant cooling device to cool silk thread.
As known by WO 2005/052224 A1, the cooling-air stream inputing to spinning station is supplied by a common cooling-air stream source.This cooling-air stream source is connected on main line for this reason, and described main line extends along spinning station, and configuration is connected with main line by corresponding supply line to the cooling device at spinning station.Therefore, the cooling-air stream supplied by main line can be input to each spinning station.In spinning station, be input to filament cluster according to the air stream of structure cooling stream as transversal orientation of cooling device or the air stream as radial directed.But also there is such possibility, namely distribute the cooling-air stream in cooling device by multiple cooling cylinder or purge plug and supply a cooling-air for each silk thread in spinning station and shunt.
In known method and known device, in each spinning station, produce identical cooling-air stream, its intensity makes a reservation for primarily of corresponding process and wire type.
In order to realize high process speed when manufacturing synthetic thread, such cooling device being provided, between cooling-air stream and silk thread, having produced relative velocity little as far as possible wherein.Therefore this cooling device needs larger flow usually, and it produces by the power improving cooling-air stream source.But show now, the flow increased in spinning station is not suitable for all running statuses.Especially just spin with silk thread repiece particularly difficult when cooling-air stream flow is larger.
Summary of the invention
Now, task of the present invention is to provide a kind of similar method and apparatus for extruding and cool many silk threads, and wherein, all spinning stations can be run with the relatively large cooling-air stream flow supplied by cooling-air stream source jointly.
Another object of the present invention is to provide a kind of method and apparatus for melt-spun and the many synthetic threads of cooling, wherein, the spinning station run of existing side by side can be supplied by a common cooling-air stream source when cooling-air stream demand is different.
The present invention realizes a kind of for melt-spun and the method cooling many synthetic threads, wherein, silk thread is extruded with the form of group and is cooled in the spinning station that the structure of multiple operation of existing side by side is identical, for spinning station inputs the cooling-air stream for cooling about silk thread respectively, and the cooling-air stream at each spinning station is supplied by a common cooling-air stream source, when constructing the running status in one of identical spinning station and changing, about the cooling-air stream flow at spinning station and cooling-air stream source independently change.
The present invention also realizes a kind of device for implementing the inventive method, it comprises the identical spinning station of multiple structure with multiple configuration to the supply line constructing identical spinning station, described spinning station has spinning manifold and the cooling device that is provided with multiple spinning head respectively, each supply line to be connected on a main line and to be connected with the cooling-air stream source of central authorities in parallel by the cooling device at each spinning station, for one of them supply line is configured for the adjusting device regulating cooling-air stream flow.
Feature of the present invention is: the cooling-air stream flow that directly can regulate input in spinning station according to current ruuning situation, and without the need to changing the main flow produced by cooling-air stream source.The worry of the flow that at least one spinning station changes to the raw adverse influence of adjacent cooling-air miscarriage at adjacent spinning station is not determined.Show, the running time running the cooling-air stream flow of reformed adjustment in a spinning station relative to tradition is relatively short and therefore can not arouse attention in the total system at all spinning stations.In addition, the running status of change only appears in several spinning stations of whole equipment usually simultaneously, and therefore in spinning station, original production process does not affect by this substantially.
On this point, the method scheme that the cooling-air stream flow at adjacent spinning station can be conditioned independently of one another is proved to be useful.Can regulate individually thus or the cooling device differently formed is set in spinning station.
Show in many application cases, the adjustment between two kinds of adjustments of cooling-air stream can realize high production security in the whole process of silk thread manufacture.Usually, in running status, cooling-air stream is adjusted in transportation load, and it provides the flow for cooling silk thread of increase.In order to break or make the reliable repiece of silk thread or just spin after process starts, cooling-air stream flow is being adjusted in shutdown amount, and it such as maintains minimum cooling-air stream.
But the shutdown amount of cooling-air stream also can be greater than the transportation load of cooling-air stream in principle, to improve some repiece process like this, cooling-air stream is made to can be used for the lax wire ends of pneumatic conveying.
The adjustment of cooling-air stream flow is preferably implemented by choke valve, and described choke valve is integrated in the supply line at spinning station.Can only to the maximum cooling-air stream throttling provided by cooling-air stream source at this.
In contrast, other method scheme allows to obtain cooling-air stream flow larger compared with cooling-air stream source.In the case, the adjustment of cooling-air stream flow is implemented by auxiliary blower in spinning station.
According to the structure of adjusting device, can manually or automatically implementation process change needed for control.In automatically controlling, choke valve is operated by the electric control actuator be connected in the control loop of control device.Proved that such scheme is particularly useful at this, wherein, silk thread monitoring unit is also connected in the control loop of control device, so that can directly utilize the signal produced during broken string to make the adaptive ruuning situation changed of cooling-air stream.
When being regulated cooling-air stream by auxiliary blower, then can simply blower motor be included in the control algolithm at spinning station.
By changing the flow for the cooling-air main flow of supplying cooling-air stream produced by cooling-air stream source, this main flow being regulated, can further improve and improve flexibility and the adjustable range of cooling-air stream change.Therefore, control the main supply of cooling-air to be such as adjusted on constant stress level, to obtain predetermined cooling-air stream flow respectively to cool silk thread on spinning station by higher level.
Following situation can be particularly advantageous for by method of the present invention, wherein, cooling-air flow to and few to be imported in balancing gate pit in one of spinning station, and cooling-air flows through this balancing gate pit is assigned to the ventilative cooling cylinder of multiple encirclement silk thread to cool silk thread.In the case, cooling-air stream is assigned to multiple silk thread with the form of each shunting in spinning station, thus can avoid the larger pressure loss.
In addition, the special advantage that silk thread cools in the cooling tube being arranged at cooling cylinder downstream is: can realize thus higher, in particular for manufacturing the spinning speed of so-called POY silk thread.
In order to implement the method, at least there is in one of the supply line at spinning station adjusting device for regulating cooling-air stream flow by device of the present invention.Thus can in spinning station indivedual adaptive cooling-air stream, these can be selected adaptive according to the corresponding running status at spinning station.
The structure being generally used for the spinning station manufactured in the whole spinning equipment of synthetic thread is identical, and the silk thread therefore produced in spinning station is respectively by the cooling device cooling that structure is identical.On this point, preferably use the expansion scheme by device of the present invention, arrange multiple adjusting device wherein, they are distributed to the supply line at each spinning station and can be conditioned independently of one another.
In order to regulate the cooling-air stream inputted by the supply line at spinning station, designing adjusting device like this, making to select between multiple switching position, to regulate cooling-air stream flow.Such as adjustable go out for cooling cooling-air stream flow needed for silk thread and the cooling-air stream flow for silk thread repiece desired when process starts.
In simple design, adjusting device can be made up of choke valve, and it to be arranged in supply line and to operate by operating personnel's manual operation or by control actuator.
But adjusting device also can be advantageously made up of auxiliary blower, it is driven by blower motor and in supply line, causes the increase of cooling-air stream.When only there being several spinning station to need the cooling air volume of increase compared with cooling-air stream source, this adjusting device is particularly favourable.
By a kind of favourable expansion scheme by device of the present invention, wherein, for control actuator and/or blower motor Configuration Control Unit, described controller and control device are coupled, and described control device connects to the silk thread monitoring unit about spinning station with configuration, and the adjustment of cooling-air stream can be carried out automatically.After determining spinning station interrupt line, silk thread is usually to sever immediately upon impact by the firing pin and is inhaled in waste station.In this stage, adjust the cooling-air stream of minimizing in the following way, namely after carrying out signal transacting, control device controls to adjust actuator or blower motor by the controller matched, and enters in the switching position of change to make adjusting device.
If the fluctuation in spinning station between the adjustment of cooling-air stream is larger, then regulate main flow by a kind of expansion scheme by apparatus of the present invention, to avoid larger volume flow fluctuation, in this expansion scheme, the main line be connected on cooling-air stream source is connected with bypass line and by-passing valve, for main line pressure sensor, and this pressure sensor and by-passing valve are coupled each other by plant control unit.Therefore predefined air pressure compass in main line is maintained by plant control unit.
But for the situation that cooling-air stream source is made up of main blower, also there is such possibility as an alternative solution, namely air blower driving device and the pressure sensor be arranged in main line are coupled each other by air compressor control device jointly.Therefore the cooling air delivery produced by main blower can be regulated in the compass determined.
Be arranged on forming preferably by balancing gate pit for the cooling device cooling silk thread in spinning station, it is that each spinning head has a ventilative cooling cylinder respectively that supply line is connected in this balancing gate pit and balancing gate pit.Each silk thread that extruded by spinning head, that be usually made up of many monofilament can be uniformly cooled thus.Cooling-air stream in balancing gate pit is divided into multiple shunting, and each shunting is towards a silk thread orientation.
When manufacturing so-called POY silk thread, in cooling tube, cool silk thread be proved to be particularly useful, wherein, the extra acceleration of cooling-air is for improving spinning speed.For this reason, the downside of balancing gate pit configures a cooling tube for each cooling cylinder.
