Description

With: Reinforcing element provided hose line and method and apparatus for their preparation

The present invention relates to a flexible tubing having a helically extending outer material web forming the outermost layer of the tubing and having a helically extending reinforcing helix secured to the outer web of material and a method and apparatus for making the same.

It is known from the prior art to produce a hose line with a helically extending reinforcing helix in such a way that a material web to which the reinforcing helix is fastened is wound around a production mandrel, the part already being wound onto the production mandrel the web is pulled axially from this, so that the web is helically wound, and at the same time the edge region of the newly encountered on the manufacturing mandrel web portion is connected to the edge region of the web portion which has already wrapped around the mandrel once. In this way, a hose can be formed, which is provided with a helically extending reinforcing element.

In particular, it is known from DE 198 48 172 A1, from which the present invention proceeds, to wind an extruded profile lug with a reinforcing coil embedded therein around a production mandrel and to connect the adjacent edge regions of the profile lug by an additional plastic introduced along the likewise helically extending seam , The additional plastic is introduced by a welding extruder. Furthermore, EP 0 694 723 B1 discloses connecting the edge regions of a material web, which is helically wound onto a production mandrel, by means of a helically extending metal profile. In particular, in the case of an extruded profile lug, however, the problem arises that the inner surface of the hose is not flat, but in the axial direction has a wave-like course, so that the diameter of the hose varies. This is due to the fact that the edge regions are heated during welding and at the same time the profile lug is under tension, so that there is a change in thickness in the region of the subsequent weld. The resulting wave-shaped course causes turbulences and dead zones to form near the wall as it flows through the hose line, which adversely affects the flow in the hose line. In addition, the wave-shaped course means that the hose is difficult to clean and soiling can remain in the hose.

Another problem that arises in the manufacture of a hose assembly from a web of material that is helical and whose edge regions are interconnected is the connection between the edge regions themselves. This always presents a weak point and can easily lead to failure This compound come when it is exposed to greater loads. This is especially true for welded joints, because when welding plastic materials, the thermal influence inevitably leads to damage to the material web.

Further, since the inner surface of the hose line formed from the material web is moved over the production mandrel and the material web is under tension when it is applied to the production mandrel, it may happen that unevennesses in the surface of the manufacturing mandrel when removing the hose damage its inner surface. This has the consequence that the inner surface of the tubing produced in the manner described above is often not is smooth, but has grooves or the like, in which in turn impurities can accumulate.

Therefore, the object of the present invention, based on the prior art, is to provide a hose line with a helically extending outer material web as well as a method and a device for the production thereof, which has an inner surface which is as flat as possible.

This object is achieved in that an inner lining, which forms the inner surface of the hose, is provided, that the inner lining is connected to the outer material web and that the inner lining is integrally formed.

According to the invention, the inner surface of the helically wound material web is provided with an inner lining which integrally, i. without welding seams or the like, extends along the inwardly facing surface of the material web. This lining can in particular be applied to the inwardly facing surface of the material web in such a way that the inner diameter is constant over the length of the hose line. By the inner lining, a wave-shaped course of the inner surface of the hose body is compensated, which is formed by the material web, and turbulence and dead zones are avoided in the hose and the flow is as far as possible evened out.

Another advantage of the liner is that the weld in the helically extending material web is reinforced towards the inside and thus is not exposed to the stresses that it would have to withstand without a liner. Thus, the hose according to the invention over the prior art is more stable. - A -

Regardless of the choice of outer material web, the inner liner material may be selected from the group consisting of polyester polyurethane, polyether polyurethane, epoxy resin, silicone, and cast polyamide. Polyester-polyurethane is associated with a high wear resistance and abrasion resistance, while a lining made of silicone ensures that the hose line has a high chemical resistance, can be exposed to high temperatures and is therefore particularly suitable for foodstuffs.

In a preferred embodiment, the reinforcing coil, which is attached to the material web, formed as a spring steel wire.

In a further preferred manner, the outer material web can be an extruded profile lug, in which the reinforcing helix is embedded. In particular, the material of the extruded profile lug can be selected from the group comprising polyester polyurethane, polyether polyurethane, LLD polyethylene, polyvinyl chloride and polyolefin. If polyester polyurethane is selected as the material of the profile lug, this leads to a comparatively high level of wear resistance. A polyethelene polyurethane tread ensures that the outside of the hose is resistant to hydrolysis, and a LLD polyethylene tread pattern provides high chemical resistance while polyvinyl chloride has high resistance to environmental influences.

As an alternative to the extruded profile lug, the outer material web may be formed as a foil strip, with the adjacent edge regions of the foil strip overlapping. Here, in a further preferred manner, the material of the film strip can be selected from the group comprising polyester-polyurethane, polyether-polyurethane and thermoplastic polyester-elastomers (TPE-E). Finally, the strip, in order to increase its stability, be provided with a reinforcing fabric.

Furthermore, it is possible for the film strip to have two film layers arranged one above the other, the reinforcing spiral being provided between the film strip layers.

In a further alternative, it is also conceivable that the outer material web is a textile web, wherein adjacent edge regions of the textile web are connected to one another via a helical clamping device. The fabric of the textile web may preferably comprise polyurethane-coated glass fabric or polyethylene-coated polyethylene fabric. A textile web is associated with the advantage of high tear resistance.

According to a further aspect of the present invention, the above object is achieved by a method in which a material web is provided, wherein a reinforcing element is attached to the material web, in which the material web is wound onto a rotating manufacturing mandrel, wherein the laid-up material web in the axial direction the manufacturing mandrel is moved, so that when winding on the production mandrel opposite edge regions of the material web come to rest, in which the adjoining edge regions are interconnected, so that a helically wound hose is formed, and wherein the hose rotates in the axial direction of the manufacturing mandrel is withdrawn, wherein on the inner surface during the axial movement, a liner made of a flowable plastic is applied.

By applying the liner as a workable plastic that is spread over the inner surface of the web, there is the advantage that the liner is then integrally formed and does not have, for example, welds or similar compounds that would represent a weak points of the hose and on the other hand would provide bumps on the inner surface. The reaction time of the liquid plastic is adjusted so that it can run and forms a smooth surface before it comes to curing.

By means of the method according to the invention can thus be made a hose, are compensated in the unevenness on the inner surface of the helically extending material web, that after removal from the manufacturing mandrel a lining of a flowable plastic is applied, in particular by applying the flowable plastic Wells are filled. In addition, the connection between the edge regions of the material web is reinforced by the inner lining, so that this compound can withstand higher loads.

Advantageously, the material of the inner lining is selected from the group consisting of polyester-polyurethane, polyether-polyurethane, epoxy resin, silicone and cast nylon, these being associated with the advantages already mentioned in connection with the hose line according to the invention.

In principle, the method according to the invention is not restricted to a specific type of material web. It is only important that the material web is guided helically around the production mandrel. In a preferred embodiment of the method, however, the material web is designed as an extruded profile lug, the reinforcing element being introduced into the profile lug during extrusion. With regard to the material of the profiled flag as well as the Related advantages will be made to the above statements on the hose according to the invention.

In order to ensure that the material of the material web and that of the inner lining form a resilient connection, it is preferred if a bonding agent is applied to the surface of the profile lug facing the lining before the lining is applied. Alternatively, it is also conceivable for this purpose that the surface of the profile lug facing the lining is plasma-treated.

In a further preferred embodiment of the method, the contiguous edge regions of the profiled lug pass through. Welding connected, which can be done in a further preferred manner by means of hot air. Alternatively, the bonding of the edge regions during winding on the production mandrel can also take place by gluing or by introducing a molten additional plastic along the edge regions.

In addition to an extruded profile lug, a film strip can also be provided as a material web, the film strip being wound onto the production mandrel in such a way that adjacent edge regions overlap. With regard to the materials of the film strip, reference is made to what has already been mentioned in connection with the hose line according to the invention. Preferably, the overlapping edge portions are joined together by welding, and the reinforcing coil is welded onto the outermost side of the film strip facing away from the liner. In this case, the reinforcing coil can be enveloped in particular by a plastic layer.

Finally, the material web can also be designed as a textile web, wherein adjacent edge regions by means of a wen- delförmig extending clamping device are connected and wherein the materials already mentioned in connection with the hose according to the invention can be used for the textile web.

According to a third aspect of the present invention, the above object is achieved by a device for producing a hose line with a device for providing a material web, with a rotationally driven production mandrel, wherein the production mandrel is arranged with respect to the device for providing a material web the material web can be supplied tangentially to the outer surface of the production mandrel, with a device for connecting adjacent edge regions of the material web on the surface of the production mandrel and with a stripping device for removing the material web welded to the edge regions from the production mandrel in the axial direction of the production mandrel, wherein a Supply device is provided for a flowable plastic and wherein a Zuführrauslauf, which is connected to the feeder, in the puller facing the facing axial end of the production mandrel see is.

The device according to the invention makes it possible to line a hose line with a helically extending material web on its inside with a flowable plastic, so that, in particular, unevenness on the inwardly facing surface of the helically wound material web can be compensated. Furthermore, the device according to the invention allows the continuous lining of the hose line, so that the lining is integrally formed and has no joints such as welds or the like. In a preferred embodiment of the device according to the invention, the device for providing a material web has an extruder and a cooling trough, so that the material web can be provided as an extruded profile lug into which a reinforcing element can be embedded during the extrusion process. In a further preferred manner, the device for connecting adjacent edge regions is designed as a hot-air welding device or as a welding extruder.

In the following, the present invention will be described with reference to a drawing showing only preferred embodiments. In the drawing shows

FIG. 2 is a cross-sectional view of a portion of the apparatus of FIG. 1 with a feeder and feed spout. FIG.

Fig. 3 shows the steps for producing the helical course of the outer material web in the hose line according to the invention and

Fig. 4 shows an embodiment of a hose according to the invention in cross section.

1 and 2 an embodiment of a device 1 according to the invention for producing a hose with a helical reinforcing spiral is shown. The present exemplary embodiment of a device 1 according to the invention initially comprises, as a device for providing a material web, an extruder 3 through which a profile flag 2 is extruded, which is shown in cross-section in Fig. 3a. Adjacent to the extruder 3, a wire coil 4 is provided, from which a spring steel wire 5 is provided, which is embedded as a reinforcing coil during the extrusion process in the profile lug 2. Finally, the device for providing a material web still has a cooling channel 6, in which the extruded profile lug 2 is cooled and via which it is fed to the rotationally driven production mandrel 7 (not shown in detail in FIG. 1).

In the illustrated embodiment of a device 1, an extruded profile lug 2 is used as the material web. However, the invention is not limited to such material webs. Rather, for example, foil strips or textile webs can be used. It is only essential that the material web used can be brought into a helical course during the production of the hose line.

The production mandrel 7 rotates about an axis of rotation, which is arranged substantially perpendicular to the longitudinal direction of the cooling channel 6, so that the profile lug 2 can be fed tangentially to the outer surface of the production mandrel 7.

To connect adjacent edge regions of the profile lug 2, a hot air welding machine 8 is provided, with which adjacent to each other on the peripheral surface of the production mandrel 7 arranged edge regions 9, 9 ^{1 of} the profile lug 2 are interconnected. This is done in such a way that hot air is blown through the welding machine 8 between the already located on the peripheral surface portion of the profile lug 2 and a newly arriving via the cooling trough 6 section. This process will be explained in more detail below with reference to FIG. The axial end of the manufacturing mandrel 7 is followed by a stripper for removing the welded at the edge regions 9, 9 'to a tubular tube body profile lug 2, which is designed as a roller table 10, wherein the roller table 10 extends in the axial direction of the production mandrel 7, so that the welded profile lug 2 can be removed in the axial direction of the production mandrel 7. The roller table 10, in turn, a take-up reel 11 is connected downstream.

As shown in more detail in FIG. 2, the device 1 according to the invention has a feed device for a flowable plastic. The feeder comprises a mixing head, not shown, with a mixing head spout 12 for mixing the components for a flowable plastic. The mixing head is connected to a Zuführrauslauf 13, which is provided in the roller table 10 and thus the stripping means facing axial end of the production mandrel 7. Furthermore, the feed spout 13 is aligned with the peripheral surface of the hose body formed by the tread lug 2, so that liquid plastic leaking from the feed spout 13 flows on the inner surface of the hose body.

Adjacent to the Zuführrauslauf 13 a scraper 14 is arranged in this preferred embodiment, which has a scraper edge 15 which is parallel to the peripheral surface of the production mandrel 7 and thus also parallel to the wall of the hose body. As a result, it is ensured by the scraper 14 that the liquid plastic is distributed uniformly over the inner wall of the hose body formed from the profile lug 2, since the hose body is rotated itself due to the rotating manufacturing mandrel 7 and is moved axially by the roller table 10. However, such a scraper 14 is not required for all lining materials. The following procedure is used to produce a hose line 16 provided with a reinforcing helix (see in particular FIGS. 3 and 4). First, a profile lug 2 made of a plastic material is produced by means of the extruder 3, wherein the plastic material itself will be discussed in more detail below. During the extrusion process, a spring steel wire 5 is embedded in the profiled lug 2 as a reinforcing helix, so that the profiled lug 2 has a cross section, as shown in FIG. 3a. In particular, the profile lug 2 edge regions 9, 9 ', which are later connected to edge regions 9, 9' of adjacent tread lugs 2, and the embedded spring steel wire fifth

The profile lug 2 with the spring steel wire 5 fastened therein is fed via the cooling trough 6 to the rotatably driven production mandrel 7, wherein the profiled lug 2 is cooled to room temperature, so that the profiled lug 2 is subsequently wound onto the production mandrel 7. At the same time, the applied profiled lug 2 is moved in the axial direction of the production mandrel 7 so that opposite edge regions 9, 9 'of the profiled lug 2 come into abutment upon winding on the production mandrel 7, as shown schematically in FIG. 3b.

The adjoining edge regions 9, 9 'are connected to one another in such a way that hot air is blown through the welding machine 8 between the section of the profile lug 2 already resting on the production mandrel 7 and the section newly arriving from the cooling trough 6, so that the edge regions 9, 9 'are first melted and, when they come to rest with each other, connect with each other. In this way, a helically wound hose line 16 is formed, which is withdrawn under rotation through the roller table 10 of the manufacturing mandrel 7. In this case, the profile lug 2 forms the outermost layer of the hose line 16. As in Fig. 3c can be seen, the inner surface of the thus produced hose 16 may still have a wave-shaped course, which would lead to turbulence and dead zones when flowing through the hose 16.

By means of the feeding device with the mixing head outlet 12, a liquid plastic is applied to the inner surface of the tubular body formed by the profiled lug 2 via the feed spout 13, taking advantage of the fact that the tubular body carries out both an axial and a rotational movement. The casting material is dosed accordingly via not shown pumps. The scraper 14 ensures a uniform distribution of the liquid plastic, so that after curing of the flowable plastic, the inner diameter of the inner lining 17 is constant over the length of the hose 16, wherein the recesses are filled in the region of the weld by the inner lining 17 ( see Fig. 4). The thickness of the lining 17 is between 0.5 mm and 10 mm. In addition, the lining 17 ensures that the weak point formed by the helically extending weld seam of the hose 16 is reinforced, so that the hose 16 is more resilient.

The fact that a flowable plastic is introduced into the hose, it follows that the inner lining is integrally formed, that no connecting lines such as welds or the like are present and that the inner surface is completely smooth. Finally, damage on the surface of the production mandrel 7 has no influence on the quality of the inner surface of the hose 16.

In the event that non-compatible plastics are to be used for the profiled lug 2 and the inner lining 17, before application of the flowable plastic a Pretreatment of the inner surface of the tubular body formed from the profile lug 2 done. On the one hand, it is possible for a bonding agent to be applied to the surface of the profile lug 2 facing the lining 17. On the other hand, the surface of the profiled lug facing the lining can be plasma-treated.

Although welding of the adjacent edge regions 9, 9 'of the profile lug 2 has been described in the present embodiment of the inventive method, the connection of the abutting edge regions 9, 9 ¹ can be achieved by gluing or by introducing a molten additional plastic along the edge regions.

While in the described embodiment of an inventive method, an extruded profile lug 2 is used as a material web, the invention is not limited thereto. Rather, other material webs can be used, provided that they can be converted into a helical course during winding onto the production mandrel 7. In particular, film strips or textile webs come into question here. When using a film strip, it is preferred if the film strip is wound onto the production mandrel in such a way that adjacent edge regions overlap, so that welding is facilitated. In addition, the film strip may comprise a reinforcing fabric. In the case of a textile web, the adjacent edge regions can be connected by means of a helical clamping device.

For the material web and the inner lining 17, among others, the following materials may be used. The material of the inner lining 17 is preferably selected from the group consisting of polyester-polyurethane, polyether-polyurethane, epoxide resin, silicone and cast polyamide selected. If an extruded profile lug 2 is used for the material web, the following materials have proved advantageous: polyester-polyurethane, polyether-polyurethane, LLD-polyethylene, polyvinyl chloride and polyolefin.

If a film strip is used for the material web, suitable materials for this purpose are polyester-polyurethane, polyether-polyurethane and thermoplastic polyester elastomers (TPE-E). In this case, the reinforcing element may be welded onto the surface of the foil strip facing away from the inner lining 17. Finally, in the case of a textile web, polyurethane-coated glass fabric or polyethylene-coated polyethylene fabric can be used as the material web.

In particular, the following exemplary embodiments of material combinations have proved to be advantageous for the hose line according to the invention and the method according to the invention.

a) Extruded profile lug as material web:

For the profile lug a polyester polyurethane Elastollan C78 A 10 from Elastogran can be used. In this case, a polyester polyurethane was also used for the lining and that Elasturan 6021/50 Elastogran. Due to the same polymers in the tread lobe and in the lining, good natural adhesion between the layers occurs here.

Furthermore, a polyether polyurethane (Elastollan 1180 AlO from Elastogran) can be used for the profile lug, and a polyester polyurethane (Elasturan 6021/50 from Elastogran) can be used for the inner lining. Such a combination has good hydrolysis resistance on the outside and good abrasion properties on the inside. In the case where an extruded profile lug is to be combined with a cold cast elastomer lining, on the one hand the combination of an LLDPE for the profile lug (Dowlex 2045 E from Dow) with a polyester polyurethane (Elasturan 6021/50 from Elastogran) proved to be advantageous for the inner lining. The inner surface of the profiled flag 2 was sprayed with Teeseal E-428/35 for bonding. Here, the outer surface has a high chemical resistance, and the inner surface has good Abriebeigenschaften.

On the other hand, here the combination of a polyvinyl chloride (PVC), namely MMPVC E 1570 Macomass, with a polyester polyurethane (Elasturan 6021/50 from Elastogran 50) for the lining has proven to be reliable, since the outer surface turn a high chemical resistance, while the inner surface of the lining has good abrasion properties.

b) If a film strip is used as material web, the following material combinations can be used in particular:

For the film strip, a polyester polyurethane (Elastollan C85 A 10 from Elastogran) can be used, while a polyether polyurethane (Elasturan 6050/60 from Elastogran) can be used for the lining. In this combination, the outer surface of the tubing has high abrasion resistance, while the inner surface of the liner has high resistance to hydrolysis.

Alternatively, a polyether polyurethane can be used both for the film strip and for the lining, namely Elastollan 1185 A 10 and Elasturan 6050/60 from the company EIA. stogran. In this case, the hose line has a high chemical resistance outside, while the inner surface has good Abriebeigenschaften.

Finally, it has proved to be advantageous in a lining with a cold cast elastomer, if for the film strip a polyester elastomer (TPE-E), namely EM 400 from Arnitel, and for the lining of a polyester polyurethane (Elasturan 6050/60 of the company Elastogran) is used. Here on the outer surface is given a good chemical resistance, while the inner surface again has good Abriebeigenschaften.

c) If a textile web is used as material web, in particular the following combinations have proven to be expedient:

For the textile web, a polyurethane-coated glass fabric was used (Pearlcoat D 152 K from Merquinsa), while for the lining a polyester polyurethane was used (Elasturan 6021/50 Elastogran). In such a combination, the outer layer of the tubing has a high tensile strength, while the inner surface is characterized by good abrasion properties.

Alternatively, it has proven useful for the textile web to use a polyethylene-coated polyethylene fabric, namely Lenzingtex ZB 210, and for the lining a polyester-polyurethane (Elasturan 6021/50 from Elastogran). In this case, a surface treatment of the textile web was carried out by means of corona discharges for adhesion promotion. Here, the outer layer also has a high tensile strength and is also chemically resistant, while the inner surface has good Abriebeigenschaften. According to the invention, a hose 16 is thus provided with a helically extending reinforcing coil and a method and apparatus for their preparation, wherein irregularities of the inner surface of the welded material web are compensated so that turbulence and dead zones are avoided in the tubing 16 and equalized the flow as much as possible becomes.

Another advantage of the hose 16 according to the invention with the inner lining 17 is that the weld in the helically extending material web is coated towards the inside and thus is not exposed to the stresses that they would have to withstand without a liner, so that the hose according to the invention over State of the art is more stable.
