Definitions
- the invention relates to a nozzle plate holder and on a spinning beam for melt spinning endless threads from in particular thermoplastic materials (melt).
- the spinning beam includes a heating box in which Melt lines, melt pumps and ends in nozzle plates Project nozzle pots (also called “nozzle packages").
- the nozzle pots can have vertical indentations in the heating box form and, in bell-shaped recordings with vertical, central melt channel attached to one Melt inlet of the nozzle pots opens.
- the nozzle plate holder forms part of a nozzle pot.
- the top (inner) end of the nozzle package the connection with a carrier in the spinning beam created (see e.g. DE-C-1246221, DE-A-1660697 and US 4,696,633). This is true even if the package from above or from the side in the designated recording must be introduced (e.g. according to US 3,655,314 or US 3,891,379).
- the nozzle pack has a flange at the bottom Fasten the end with screws - see for example US 4,494,921.
- the fastener is mentioned in the Example used to provide the required sealing forces (by squeezing a sealing ring on the top End of the package). An air gap therefore remains between the flange and the support (the heating box).
- a well-known spinning beam is from, for example DE-Gbm 84 07 945.
- the receptacle for the nozzle pot (the nozzle package) in the The heating box is welded in and therefore a practical component of the heating box.
- the arrangement of the nozzle pot in the holder is designed so that a stratification consisting of Nozzle plate, filter housing and nozzle pot bottom to the bottom the receptacle is screwed on, by means of the layering penetrating bolt, which in a nut thread in Are screwed in because of the recording.
- the layering penetrating bolt which in a nut thread in Are screwed in because of the recording.
- the nozzle pot with its components the screws be loosened, after which the nozzle pot extends vertically downwards the holder can be pulled out.
- the nozzle pots need to be cleaned frequently, sometimes daily, by what depends on the mass to be processed, there is a considerable Wear of the bolts in the area of the nut thread in the bottom of the recording.
- the bolts must be because of the Nozzle pot usually prevailing pressures from about 120 to 350 bar strong, which is to avoid Damage to the bolts and the thread with a torque wrench must be done.
- the Attachment of a nozzle cup requires at least four bolts, so that for every cleaning of the nozzle pot too results in a significant amount of work.
- a nozzle pot in a receptacle in Connection with a spinning beam is from the European Patent 163 248 known (see in particular Figures 3 and 6).
- the nozzle pot has one Hollow cylinder on that with an inwardly projecting paragraph carries the nozzle plate on which the filter housing over a Ring seal is stored.
- the unfilled nozzle pot over a membrane in the manner of an inverted plate supports the bigger picture.
- the piston stroke is during this movement through a sealing ring surrounding the central recess limited, which is supported against a threaded ring which by means of bolts with one arranged in the heating box rigid pump block is attached.
- a threaded ring which by means of bolts with one arranged in the heating box rigid pump block is attached.
- the hollow cylinder On the one with an external thread provided threaded ring is the hollow cylinder with screwed on an internal thread, which means that of the hollow cylinder nozzle pot carried with its heel attached to the heating box is.
- the hollow cylinder is used to remove the nozzle cup unscrew from the ring nut.
- the thread and the Membranes of this arrangement are subject to a very considerable Load because of the fact that over the entire cross section of the interior of the hollow cylinder extending sealing membrane this and the thread with one by the pressure and the specified cross-section are subjected to certain force, the because of the relatively large cross section of the interior of the hollow cylinder can be up to 15 t.
- the arrangement of the thread near the A necessary reason for the holder for the filter bowl free annular space between the outer surface of the hollow cylinder and the opposite wall of the heating box, because for the screwing and unscrewing of the hollow cylinder a certain Game is required.
- the consequence of this is one by the Annulus interrupted heat transfer from the concerned Wall of the heating box to the hollow cylinder, especially in its Area where he carries the nozzle plate with his heel, so that the necessary constant adequate heating the nozzle plate is difficult.
- the invention has for its object the assembly and Disassembly of the nozzle pots with reduced stress on the seal to facilitate, in particular to accelerate.
- the sealing washers are advisable to form with a central one Through hole bell-shaped, being built in Condition with its bottom surrounding the through hole on The reason for the recordings and the outer edge of the Support sealing washers on an annular shoulder in the nozzle cup. Because of this design of the sealing washers when the nozzle pot is filled, they press under the Pressure of the melt on the one hand at the bottom of the intake, with which the sealing effect between the nozzle pot in the area the central through hole of the sealing washer and the Due to the admission automatically to the prevailing Adjusts pressure.
- the nozzle pots are designed so that in one Hollow cylinder of the nozzle cup, the nozzle plate, a filter housing and above it the nozzle pot bottom with a central recess forming threaded ring are layered, the hollow cylinder with a shoulder carries the nozzle plate and the threaded ring into a nut thread of the hollow cylinder under compression the layered components is screwed in the annular shoulder the sealing washer arranged on the filter housing against a conical inner surface of the threaded ring so that the sealing washer with its through hole surrounding area from the central recess of the Thread ring appears slightly.
- the sealing washer receives one Centering through the conical inner surface of the threaded ring, so that after assembling the nozzle pot with correct position of the sealing washer by means of the above Bayonet lock can be attached in the receptacle.
- the sealing washer immediately presses into its correct position against the bottom of the shot, with which the nozzle pot for the Filled with the mass to be processed and sealed is prepared.
- the filter housing expediently so that when the nozzle pot is assembled the filter housing with a cylindrical projection abuts the nozzle plate and the projection is ring-like Surrounding recess in the filter housing in which a sealing ring is inserted.
- the shoulders arranged on the receptacles are useful and the conditions provided on the nozzle pots kind of a bayonet lock trained. This gives a particularly easy to close and connection to be released between the nozzle pot and the receptacle, namely only by turning at most about 90 °. Accordingly, the bayonet lock also joins frequent removal of the nozzle bowl practically no wear on.
- Fig. 1 shows the heat flows on a nozzle package.
- the melt makes up the majority of the Heat supply as well as heat dissipation. Ideally you are both heat flows equal in amount. That would mean, that the melt is one until it emerges from the nozzle has constant temperature. To ensure this would have to the other heat flows are in balance. Special Difficulties are caused by the heat loss from the nozzle plate. Since it cannot be isolated, a most of the heat in the form of radiation and convection released to the environment. This amount of heat must now as far as possible from the spinning beam to the nozzle package to the nozzle plate to cool the Reduce melt to a minimum.
- the temperature difference to the diphyl temperature represents here is a measure of the amount of heat, that of the melt is withdrawn.
- FIG. 5 shows a section of a spinning beam with a nozzle pack (in particular a nozzle plate holder) according to this invention.
- the spinning beam includes a heating box 1, in the fuse lines and not shown Melt pumps protrude, such as this in the Figures of the above-mentioned DE-Gmb 84 07 945 is shown.
- the receptacle 2 is used, for example by welding, which consists of the wall 3, which is completed on the inside by the bottom 4 ago.
- the receptacle 2 encloses the cylindrical interior 5, in which the nozzle pot 6 is inserted.
- the Interior 5 through the cylindrical opening 7 into the exterior about.
- the bottom 4 is penetrated by the melt channel 8, connected to a melt pump, not shown is.
- the nozzle pot 6 is a rotating body, it is in the figure as the picture 2 shown in section.
- the nozzle pot 6 consists of stacked components, namely from the nozzle plate 9, the filter housing 10 and the threaded ring 11. These three components are inserted in the hollow cylinder 12, who carries the nozzle plate 9 with his shoulder 13.
- On the side of the threaded ring 11 is the hollow cylinder 12 with the internal thread 14 into which the threaded ring 11 with its external thread 15 is screwed.
- the threaded ring 11 provided with the blind holes 16 and 17, in the a suitable hook wrench fits.
- the screwing in of the Threaded ring 11 in the hollow cylinder 12 is through the cylindrical Projection 18 on the nozzle plate 9 facing side of the filter housing 10 limited. If at Screwing in the threaded ring 11 of the projection 18 on the Surface 19 of the nozzle plate 9 rests is the entire Length of the nozzle cup 6 determined. Inside the cylindrical Projection 18 there is an annular recess, which is filled by the sealing ring 20. Of the Sealing ring 20 is a pressure to be processed Mass, the gap 21 between the surface 19 and the bottom surface 22 of the filter housing 10 fills, outwards against the cylindrical projection 18 pressed, which automatically under the effect of this pressure a seal adapted to the pressure between the filter housing 10 and the nozzle plate 9 results.
- the hollow cylinder 12, which is part of the nozzle pot 6 with its paragraph 13 carries the nozzle plate, in turn held in the receptacle 2 by means of the shoulder 23, the supports 24 in the installed state shown face each other on the hollow cylinder 12.
- the shoulders are 23 Components of the insert pieces 25, which in the wall 3 of the Insert 2 inserted and screwed to the wall 3 by means of the bolts 26.
- the shoulders 23 and the supports 24 together form a bayonet catch, which axially locks the nozzle cup 6.
- the Bayonet lock over the shoulders 23 and the pads 24 a direct thermal bridge over which the nozzle plate 9 directly is heated.
- Sealing washer 27 for action which is essentially conical Training is inserted in the threaded ring 11, the for the purpose of receiving the sealing washer 27, a conical inner surface 28 has.
- the sealing washer 27 is supported with its outer edge 29 on the ring shoulder 30 from Part of the lying on the filter housing 10 Melt distributor 31 is.
- This melt distributor 31 is here part of the nozzle pot 6, it serves to over the melt channel 8 flowing melt inside the To distribute nozzle pot cheaply, which was discussed in more detail below becomes.
- the bottom 32 of the sealing washer 27 slightly opposite the surface 34 of the threaded ring 11 so that when closing the bayonet catch 24/25 the floor 32 to the lower surface 35 of the bottom 4 of the Recording 2 is tight. So that the seal is between the bottom 4 of the receptacle penetrated in front of the melt channel 8 2 made to the nozzle pot 6, and by using the pressure prevailing inside the nozzle pot 6, of the sealing washer 27 depending on the level of this pressure against the lower surface 35 and the conical inner surface 28 of the Thread ring 11 presses. In addition, the sealing washer 27 radially outwards against the joint 36 between the threaded ring 11 and filter housing 10 pressed so that too a secure seal is achieved here.
- the melt flow in operation is as follows: The Melt passes from the melt channel 8 through the through hole 33 to the melt distributor 31, which the melt overflows and reaches the channels 37, of which only two are drawn. In the illustrated embodiment there are about 24 such channels.
- the filters 40 introduced approximatelyx. 50 such channels are present, from where the melt enters the gap 21 arrives.
- the melt passes through the nozzle plate 9, namely through the bores 41, which are in capillaries in the lower boundary surface 42 of the nozzle plate 9 end.
- the individual filaments emerge, which then become individual Threads are summarized.
- dashed curve A represents the warm-up behavior (Temperature curve over time after installation in the Spin beam - without polymer) of a conventional nozzle package in the middle of the nozzle while the dashed curve B the corresponding behavior in the marginal part of a conventional one Package shows.
- Curve C shows that Warm-up behavior in the middle of the nozzle of a package after this Invention (e.g. according to Fig. 5), while curve D (the for the most part coincides with curve C) the warm-up behavior represents the edge of the new package.
- the new nozzle package with the improved heat flow achieved the final temperature much earlier than the conventional nozzle package Construction. Furthermore, the final temperature of the new nozzle package in about 10 ° C higher, which the calculations corresponds. The temperature difference between the center of the nozzle and nozzle edge is more conventional with the nozzle package Construction already negligible, but could the new nozzle package can be improved by the last nuance.
- the experiment thus confirms the calculated results, after which cooling of the melt in the new nozzle package by approx. 0.5 ° C is lower than with the conventional nozzle package Construction. This value appears to be very low but especially in the manufacture of microfilaments of crucial importance for the quality of the produced Yarn.
- FIG. 7A shows "optimal" conditions in the area of the melt feed in the "nozzle throat", that means in the admission in the Heating box which receives the nozzle package.
- the recording itself has an axial surface 100 that faces in the spinning direction is directed. This surface is on one end 102 of the nozzle pack opposite after the pack in their Is in the operating position, with a gap 104 therebetween is available. The distance between the end face 102 and the contact surfaces of the pad can be used in the manufacture or the assembly (i.e. in the construction) of the package be determined without the manufacturing tolerances of the To have to consider heating box.
- a flexible sealing lip 106 extends from the out the top of the package to touch surface 100.
- the hardness, flexural strength and dimensions of the flexible Lips are chosen in such a way that surface to surface contact 7A comes about. Ideally hugs the lip adjusts to unevenness in the surface 102.
- the risk of leakage between the lip and the surface 102 is at the first entry of the melt through the access channel small because the melt pressure is low until the chamber in the package below the lip. Until this takes place, the lip is also opposed by the melt surface 102 is pressed, which counteracts the risk of leakage.
- the lip is provided on a sealing body which in the Package is "embedded" so that the body is against the package the melt pressure is supported, and only the lip itself must deform under the melt pressure.
- the Lip formed in one piece with the body.
- the body can are advantageously formed or arranged such that it take on additional sealing functions in the package itself can.
- the sealing element (the lip) can be under the operating pressure be plastically deformable, the element then after removing the package from the throat before relaunching needs to be replaced.
- the material of the element can be chosen so that the element also under the Operating pressure is elastically deformable and therefore reusable is, for example if a chrome steel is used.
- the seal is preferably elastically deformable.
- the sealing element (the sealing lip and the sealing body) are exposed to the melt during operation. It must therefore, a sealing material should be chosen that with the Melt will not respond.
- a metal is preferred aluminum and steel are suitable in most cases are.
- a seal according to Fig. 5 (with a lip and a Body part from one piece), the conical body part in contact with a conical support surface in the Package is standing, e.g. by a deep drawing process or be formed by metal pressing.
- a sheet thickness up to approx. 3 mm e.g. for steel approx. 1 mm and for aluminum 1.5 to 2 mm can be used.
- the package is preferably provided with a stop, which in the operating position of the package its angular position around a vertical axis. This can the arrangement of the holes in the nozzle plate compared to the Cooling shaft can be predetermined. Where the connection with the Carrier accomplished by means of a bayonet lock at least one element of the closure can Exercise the function of the stop.
- a multi-turn bayonet lock could be used measures may then have to be taken in order to the surface pressure over the support of the closure to distribute. This will usually result in tighter manufacturing tolerances require. Because the radial dimension of these conditions the division (the mutual distance) of the packets in the Spinning beam heavily influenced, this dimension should be possible be kept small because of a minimal division is generally desirable.
- the radial distance between the outer surface of the package and the outer end of each The support is preferably not larger than 10 mm. In the case A multi-course lock can make this dimension smaller be held as 5 mm. There are preferably no more available as three editions per course.
- the invention in its first aspect (connection at the bottom End of the package) results in the shortest possible flow paths for the Heat between the heater box and the nozzle plate.
- This Aspect of the invention is not to be used in combination constrained with a sealing lip, though preferably used in combination with a seal the full sealing effect due to the melt pressure developed.
- Such seals are also made, for example US 4645444 known.
- the new type of seal is independent of the connection between the nozzle pack and the heater box, from Advantage - it can, for example, adjust the piston seal DE-C-12 46 221 or DE-C-15 29 819 or US-4 696 633 replace.
- nozzle 5 is the cylindrical outer surface of the nozzle package indicated with M. This area must be a little smaller Have diameter than the inner surface of the nozzle pharynx, to easily insert the package into the throat enable.
- the radial dimension of the edition is indicated with D.
- the concept of a link at the bottom of the package requires the appropriate design of the lower one End of the jet throat. This can be done by designing the Heating box itself happen, but preferably one Support frame for the package formed separately and on the heating box attached, for example by means of screws, as in Fig. 5 is shown.
- the frame is preferably interchangeable, that means the fasteners can be loosened without Destroy parts.
