Description
- This application is a continuation of prior filed copending PCT International application no. PCTIEP2006/050118, filed Jan. 10, 2006, which designated the United States and has been published but not in English as International Publication No. WO 2006/074994 A1 and on which priority is claimed under 35 U.S.C. §120, and which claims the priority of German Patent Application, Serial No. 10 2005 001 782.7, filed Jan. 14, 2005, pursuant to 35 U.S.C. 119(a)-(d), the contents of which are incorporated herein by reference in its entirety as if fully set forth herein.
- The present invention relates to an apparatus for calendering continuously produced articles.
- Nothing in the following discussion of the state of the art is to be construed as an admission of prior art.
- German Offenlegungsschrift DE 28 56 096 discloses an extruder and calender combination to produce profiled sheets of elastomer or stamped films of thermoplastic materials. Plastic masses are plasticized by an extruder and further processed by means of a calender which has profiled rolls.
- German Pat. No. DE 44 12 862 C1 discloses a roll changer for exchange of rolls on a calender to maintain product tolerance even when exposed to high stress.
- It would be desirable and advantageous to provide an improved calendering apparatus to obviate prior art shortcomings.
- According to one aspect of the present invention, an apparatus for calendering continuously produced articles, includes at least one calender roll, a drive having a driveshaft constructed as a cardan shaft and operatively connected to the at least one calender roll for rotating the at least one calender roll, and a rotary hollow-shaft feedthrough having fluid passageway means for circulation of a temperature control medium to maintain the at least one calender roll at a desired temperature, wherein the rotary hollow-shaft feedthrough has a first fluid passageway for providing a passageway to the driveshaft for introduction of temperature control medium into the driveshaft, and a second fluid passageway for providing a passageway for discharge of the temperature control medium from the rotary hollow-shaft feedthrough.
- In order to ensure clarity, the term “temperature control” as used throughout the description refers to any tempering process, involving heating or cooling of the at least one calender roll.
- The present invention resolves prior art problems by distributing the temperature control medium through the rotary hollow-shaft feedthrough into the at least one calender roll in order to attain a reliable and cost-effective temperature control of the at least one calender roll. Introduction of temperature control medium via the rotary hollow-shaft feedthrough is easy to implement and does not require the use of special mechanisms. By constructing the driveshaft in the form of a cardan shaft, the at least one calender roll can easily be installed and there is no need to precisely align the drive and calender to prevent leakage.
- According to another feature of the present invention, the temperature control medium distribution may be realized by an annular gap provided in the rotary hollow-shaft feedthrough. The provision of such a temperature control medium distribution in the rotary hollow-shaft feedthrough simplifies the introduction of temperature control medium into the driveshaft. Suitably, the annular gap is in fluid communication with the first passageway. As a consequence, temperature control medium, which is present in the annular gap for example and passes the periphery of the rotary hollow-shaft feedthrough, can easily be introduced into the driveshaft.
- According to another feature of the present invention, the driveshaft may be constructed to allow temperature control medium to flow into the interior of the at least one calender roll. The introduction of the temperature control medium into the at least one calender roll may hereby be implemented via a first conduit which extends, at least in part, within the driveshaft and/or at least one calender roll and is arranged in preferably concentric relationship to the rotation axis of the driveshaft and/or at least one calender roll. This conduit may be designed in various ways, for example as pipeline which extends into the at least one calender roll concentrically within the driveshaft. The conduit may hereby be provided within the driveshaft with an opening in fluid communication with the first passageway 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 constructed to allow discharge of temperature control medium from the interior of the at least one calender roll. The removal of temperature control medium from the at least one calender roll may hereby be realized by a second conduit which extends, at least in part, within the driveshaft and/or at least one calender roll and is arranged in preferably concentric relationship to the rotation axis of the driveshaft and/or at least one calender roll.
- According to another feature of the present invention, the second conduit for removal of the temperature control medium may be arranged in concentric relationship about the first conduit for introduction of the temperature control medium into the at least one 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 at least one calender roll and removed from the at least one calender roll at the outer part of the double conduit.
- The provision of the second passageway in the rotary hollow-shaft feedthrough permits an exchange of temperature control medium and establishment a temperature control medium circulation. As a consequence, the temperature control medium, which is removed from the at least one calender roll, can be conducted through the system comprised of the at least one calender 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 at least one calender roll to thereby establish a temperature control circulation. The second passageway for discharge of temperature control medium may hereby be in fluid communication with the temperature control medium in the driveshaft.
- According to another feature of the present invention, a pump may be provided for transport of the temperature control medium. This pump may be designed in any manner known to an artisan.
- According to another feature of the present invention, the at least one 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 at least one calender roll is realized on the driving side of the at least one 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 at least one calender roll could be implemented from the driving side. As a result, when using a changeable sleeve calender, the sleeve is shifted to the side that is not driven. The use of a common rotary feedthrough on this side would be difficult.
- Other features and advantages of the present invention will be more readily apparent upon reading the following description of currently preferred exemplified embodiments of the invention with reference to the accompanying drawing, in which:

Thepassageway 7 is always in fluid communication with theannular gap 6, even when thedriveshaft 5 rotates. - The
driveshaft 5 is hereby designed in such a way that the temperature control medium can be directed into the interior of thecalender roll 1. As shown in particular inFIG. 2 , this is realized by theconduit 8 which extends within thedriveshaft 5 and thecalender roll 1 in concentric relationship to the rotation axis of thedriveshaft 5 and thecalender roll 1. - The
driveshaft 5 is furthermore designed in such a way that the temperature control medium can be removed from the interior of thecalender roll 1.

conduit 8 is centered in thedriveshaft 5 by a bushing 11 and at the same time sealed by the bushing 11 from theouter conduit 9. Theconduit 9 is also connected to the surface of thedriveshaft 5 by aradial bore 9′. The rotary hollow-shaft feedthrough 4 has afurther passageway 10 which is intended for discharge of temperature control medium from the rotary hollow-shaft feedthrough4 and fluidly connected to theconduit 9 at the surface of thedriveshaft 5. As a result, temperature control medium can be discharge from thecalender roll 1. Thepassageway 10 is hereby in fluid communication with anannular gap 6″ which enable a drainage of temperature control medium via adischarge bore 6′″. in theouter jacket 4 of the rotary hollow-shaft feedthrough 4. - As also shown in
