Description
Description Title Apparatus For Calendering Continuously Produced Articles Using At Least One Calender Roll The invention relates to an apparatus for calendering continuously produced articles, flat products, using ay least one calender roll, wherein the calender roll can be caused to rotate by means of at least one drive, wherein at least one calender roll is temperature-controllable and the temperature control of the calender roll is realized by means of a temperature control medium.
Apparatuses for calendering elastomers - rubber mixtures - or thermopiastic materials into articles, like flat products for example, such as profiled or unprofiled sheets or films, have been known in practice for some time. Oftentimes, this involves the use of extruder-calender-installations which process elastomers or thermoplastic materials. These types of apparatus are frequently used, when the production of profiled sheets of elastomers or stamped films of thermoplastic materials are desired, with the calender having rolls being provided with a profile.
Such an apparatus is illustrated in DE 28 56 096 Al for example. Plastic masses are plasticized in this apparatus by means of an extruder and further processed by means of a calender. The calender has rolls for processing the plasticized material. Furthermore, DE 44 12 882 Cl discloses roll changing apparatuses which allow quick execution of an exchange of rolls on a calender so as to maintain a very good production tolerance even when exposed to high stress.
In other prior art constructions, the rolls of a calender are operated by means of a complicated joint coupling and a special hollow-shaft gear mechanism. The roll is temperature-controlled via a rotary feedthrough by means of a double pipe through the special gear mechanism and through the joint coupling. Also these designs have the afore-stated problems. Moreover, sealing the temperature control medium circulation is problematic, and the drive and the calender roll must be aligned to one another in a very precise manner.
The present invention is thus based on the object to provide a calendering apparatus a type as mentioned above, which allows a simple and cost-effective construction.
The afore-stated object is attained in accordance with the invention by the apparatus for calendering having the features set forth in claim 1. The concerned apparatus is hereby constructed and developed in such a way that the temperature control medium can be introduced through a rotary hollow-shaft feedthrough into a driveshaft that operates the calender roll.
It has now been recognized in a manner according to the invention that the temperature control medium can be distributed through the rotary hollow-shaft feedthrough into the calender roll in order to attain a reliable and cost-effective temperature control of a calender roll, as opposed to current practice which introduced the temperature control medium solely by means of the driveshaft through the rotary hollow-shaft feedthrough into the calender roll.
Temperature control is hereby to be understood as including heating or cooling of the roll.
Introduction of the temperature control medium via the rotary hollow-shaft feedthrough eliminates the need for expensive special gear mechanisms.
A particularly cost-effective construction could be realized by configuring the driveshaft as hollow shaft and/or as cardan shaft. As a result, the rolls can be installed more easily as there is no longer a need to precisely align the drive and calender to ensure tightness.

Temperature control is hereby to be understood as including heating or cooling of the roll.
Introduction of the temperature control medium via the rotary hollow-shaft feedthrough eliminates the need for expensive special gear mechanisms.
A particularly cost-effective construction could be realized by configuring the driveshaft as hollow shaft and/or as cardan shaft. As a result, the rolls can be installed more easily as there is no longer a need to precisely align the drive and calender to ensure tightness.
A particularly simple construction could be realized by providing a temperature control medium distribution in the rotary hollow-shaft feedthrough. This would enable a particularly simple introduction of the temperature control medium into the driveshaft.
According to a particularly simple construction, the temperature control medium distribution may be realized by an annular gap provided in the rotary hollow-shaft feedthrough. In addition, or as an alternative, the rotary hollow-shaft feedthrough may be provided with an opening toward the driveshaft of the calender roll. As a consequence, introduction of the temperature control medium, which is present in the annular gap for example and passes the periphery of the rotary hollow-shaft feedthrough, would be possible into the driveshaft in a particularly simple manner.
The driveshaft could hereby be configured in such a way that the temperature control medium can be routed into the interior of the calender roll. According to a particularly simple construction, the introduction of the temperature control medium into the calender roll may be implemented via a conduit which extends, at least in part, within the driveshaft and/or calender roll and is arranged in preferably concentric relationship to the rotation axis of the driveshaft and/or calender roll.
This conduit may be designed in various ways, for example as pipeline which extends into the calender roll concentrically within the driveshaft. The conduit may hereby be provided within the driveshaft with an opening toward the opening of the rotary hollow-shaft feedthrough so that the temperature control medium, introduced through the rotary hollow-shaft feedthrough into the driveshaft, can be accepted by the conduit.
In addition, or as an alternative, the driveshaft may be designed in such a way that the temperature control medium can be removed from the interior of the calender roll. According to a particularly simple construction, the removal of the temperature control medium from the calender roll may be realized by a conduit which extends, at least in part, within the driveshaft and/or calender roll and is arranged in preferably concentric relationship to the rotation axis of the driveshaft and/or calender roll. According to a particularly preferred embodiment, the conduit for removal of the temperature control medium may be arranged in concentric relationship about the conduit for introduction of the temperature control medium into the calender roll. The conduit can thus be constructed in the form of a double conduit in which the temperature control medium can be introduced within the double conduit into the roll and removed from the calender roll at the outer part of the double conduit.
The exchange of the temperature control medium or to form a temperature control medium circulation can be realized by providing the rotary hollow-shaft feedthrough with a further opening for the temperature control medium to issue out. As a consequence, the temperature control medium, which is removed from the calender roll, can be conducted through the system comprised of roll, conduit and rotary hollow-shaft feedthrough; For example a temperature control unit may be provided for allowing a temperature control of the temperature control medium.
The temperature control medium having now a desired temperature can then be fed to the calender roll to thereby establish a temperature control circulation. The further opening for discharge of the temperature control medium may hereby be in fluid communication with the temperature control medium in the driveshaft.
Furthermore, a pump may be provided for transport of the temperature control medium within the apparatus. This pump may be designed in any conventional manner.
According to a particularly cost-effective construction, the calender roll may be configured with a changeable sleeve. In this context, it would be of particular advantage, when the side via which the changeable sleeve is replaced would be especially easy to access because the temperature control of the calender roll is realized on the driving side of the calender roll, so that the need for cumbersome assembly and/or disassembly works is eliminated in the event a sleeve needs to be replaced. In addition, or as an alternative, the temperature control of the calender roll could be implemented from the driving side. This would be especially advantageous, when the apparatus involves a changeable sleeve calender because the sleeve is shifted in this case to the side that is not driven. The use of a common rotary feedthrough on this side would be difficult.
There are various possibilities to implement and improve the teaching of the present invention in an advantageous manner. In this context, reference is made to the claims following claim 1, on one hand, and to the following description of a preferred exemplary embodiment of the calendering apparatus according to the invention with reference to the drawing. In combination with the description of the preferred exemplary embodiment of the calendering apparatus according to the invention with reference to the drawing, also generally preferred configurations and improvements of the teaching are described. In the drawing, there is shown in:
Fig. 1 a schematic illustration of an exemplary embodiment of an apparatus for calendering in accordance with the invention, and Fig. 2 a schematic, sectional illustration of the exemplary embodiment of Fig.

The calendering apparatus represented by the illustrated exemplary embodiment includes two calender rolls 1, 2, wherein the calender rolls 1, 2 can be caused to rotate by means of a drive 3. The calender roll 1 is hereby constructed temperature controllable, with the temperature control being realized by a temperature control medium.
In accordance with the invention, the temperature control medium is introduced through a rotary hollow-shaft feedthrough 4 into a driveshaft 5 that operates the calender roll 1. Advantageously, the driveshaft 5 is constructed as a cardan shaft.
A temperature control medium distribution 6 is provided in the rotary hollow-shaft feedthrough 4 for distribution of the temperature control medium and is configured in this exemplary embodiment in the form of an annular gap 6. The rotary hollow-shaft feedthrough 4 includes an opening 7 toward the driveshaft 5 of the calender roll 1. This opening 7 may be used for routing the temperature control medium, which passes through the annular gap 6 of the rotary hollow-shaft feedthrough 4, out of the rotary hollow-shaft feedthrough 4.
The driveshaft 5 is hereby designed in such a way that the temperature control medium can be routed into the interior of the calender roll 1. This is realized by a conduit 8 which extends within the driveshaft 5 and the calender roll 1. The conduit 8 extends hereby in concentric relationship to the rotation axis of the driveshaft 5 and the calender roll 1. The driveshaft 5 is hereby furthermore designed in such a way that the temperature control medium can be removed from the interior of the calender roll 1.
The removal of the temperature control medium from the calender roll 1 is realized by a conduit 9, with the conduit 9 extending within the driveshaft 5 and the calender roll 1 in concentric relationship to the rotation axis of the driveshaft 5 and the calender roll 1. The conduits 8 and 9 are constructed in this concrete embodiment in the form of a conduit with two fluid paths, i.e. as double conduit, so that the temperature control medium is introduced inside the double conduit, i.e. in the conduit 8, into the calender roll 1, and the conduit 9 is configured as hollow conduit, in which the conduit 8 extends, so that the temperature control medium issues out of the calender roll 1 at the outer part of this double conduit.
There is provided a bushing which is arranged, preferably in midsection, between the radial bores. This bushing is arranged in this exemplary embodiment of the driving side of the double conduit; it could, however, also be arranged differently.
The rotary hollow-shaft feedthrough 4 has in addition a further opening 10 intended for discharge of the temperature control medium from the rotary hollow-shaft feedthrough 4. The further opening 10 is hereby in fluid connection with the temperature control medium in the driveshaft 5.
In order to avoid repetitions, reference is made to the general description for further details.
Finally, it is expressly noted that the afore-described exemplary embodiment is intended solely for explanation of the claimed teaching which, however, is not limited to the exemplary embodiment.
