Technical field
The calender that the present invention relates to a kind of for handling nonwoven webs band, webs band, plastics web or paper product web,
Especially so-called double calenders comprising rack and at least two rollers, the roller can respectively selectively be displaced to work
Gap and can be alternatively displaced in stand in position with being constituted processing with corresponding tool, and can respectively by
The driving unit independently of the bearing of corresponding roller in itself is driven in rotation.
In order to handle material roll band, in calender it is known material roll band to be processed is transported on direction of propulsion and
The processing gap that guidance is made up of the roller (also referred to as treatment tube) being located in operating position and corresponding tool (such as respective roller).
Treatment tube is usually disposed as upper roller herein and respective roller is arranged to lower roll, wherein only upper roller is driven in rotation mostly, or on
Roller and lower roll are driven in rotation.The driving device is for example realized by means respectively of the driving unit for being configured to motor, wherein driving
Moving cell optionally additionally can have transmission device and/or clutch or similarity piece to transmit for power.The present invention is especially
It is related to the driving unit for the treatment tube being arranged as upper roller, wherein driving device is currently especially carried out independently of or separately from roller
Bearing, is not supported on especially on the carrier such as roller library or pivot rods of a bearing roller.
Background technique
As in above-mentioned material roll tape handling, usually (such as handling type or based on abrasion to replace) exists
Necessity, i.e. replacement treatment tube.In order to avoid therefore usually there is the expectation of quick-replaceable treatment tube in long downtime.For
This, it is known that calender, wherein being arranged in calender rack one or more arranging and carrying respectively for quick-replaceable roller
The pivot rods of one or more rollers, (capstan head) roller library or other roller quick replacement devices, by them respectively by one or more
A roller can be shifted into operating position or stand.Displacement of the roller between stand and operating position can be in this principle
On linearly, with arch or along curvilinear path realize.

Body (capstan head roller library form) be it is adjustable, a roller and a respective roller is selectively arranged.In order to rotate driving difference
Only one drive motor is arranged in roller in respective roller region, can be via a drive coupler and respectively at this
The roller connection being arranged in region.
In such an arrangement adversely in particular, it is corresponding not with the roller in stand of corresponding tool engagement not
It may be driven, no longer be rotated again.It thus may be therefore in such roller (especially answering in time in corresponding roller
Before or after when process is heated or cooled) lead to the sagging of corresponding roller, this might mean that huge economic loss.
Furthermore such coupler needs the relatively high locational requirement in the axial side zones of roller and (also because coupling

Figure part in show) in when, be movably supported on track 125, the slide 121a on 125' together with the drive being disposed thereon
Moving cell 120a is mobile towards stand P transverse to the longitudinal axis M1 of roller 10a.Be likely to occur herein from driving unit
The driven shaft not being shown specifically and the dislocation between the drive shaft of roller side setting not being shown specifically equally that 120a stretches out are borrowed
Help the universal shaft 122a being arranged between the two axis, particularly is mended by two universal joints being arranged on the universal shaft
It repays.Therefore roller 10a can be further driven in rotation in shifting process and in stand P, this is especially for keeping away
Exempt from the sagging of roller 10a.
It is next pivoted in the A1 of operating position between 20 formation of lower roll processing in the roller 10b being located in stand P
When gap 102, the slide 121b that is equally supported on track 125,125 ' together with the driving unit 120b being disposed thereon transverse to
The longitudinal axis M2 of roller 10b is mobile towards operating position A1.What is be likely to occur herein is not detailed what is stretched out from driving unit 120b
The driven shaft shown and the dislocation between the drive shaft of roller side setting not being shown specifically equally are by means of being arranged at the two
Universal shaft 122b between axis, particularly pass through two universal joints being arranged on universal shaft compensation.Roller 10b therefore can be with
It is just placed into rotation in stand P before shifting process, this is for example to have in the case where the heating process of roller 10b
Benefit.
In the embodiment of the calender shown in Fig. 1 to 3, the driven shaft and being especially for drive shaft illustrated before is erected
Straight dislocation can compensate respectively by means of universal shaft 122a, 122b.In sizable dislocation (as example in stand P
May be this situation) when, it may be necessary to, rotation speed is limited to defined maximum value, however is apparently higher than always
For example in order to avoid the sagging and commonly required rotation speed wanted in stand P.In order to can also even if in stand
To realize extra high rotation speed, (as in Fig. 4 in the embodiment shown in example) dislocation can also remain lesser.
In the embodiment being especially shown in FIG. 4, when institute is shifted between stand P and operating position A1 in roller 10a, 10b
Stating dislocation can also so keep that smaller (this is synchronous with corresponding driving unit 120a, 120b's especially by roller 10a, 10b
Displacement identical with speed realize), so that roller 10a, 10b also can be placed into extra high rotation speed in the displacement.
It is noted that protection scope of the present invention is not limited to described embodiment.In particular, of the invention not changing
In the case where core, calender, the structure of roller shift unit and roller and design can carry out very big transformation.Therefore, it moves
The driving unit that ground is supported at least one guiding piece for example even can linear displacement roller in the case where apply.
