In an embodiment of the present invention, preferably, thereby the backing roll group supports the below that this body frame of whole roller group is positioned at this machine position at least in part.In this case, to this this body frame and the way of realization that is used for described roller group, in this base, be provided with hollow bulb according to the present invention.When only partly seeing described roller group at place, this machine position, necessary hoisting depth reduces, and the top free state of fibre-web machine increases in same machine shop, and this viewpoint from hoisting depth is favourable.
According to the present invention, described roller group can or also can comprise at least two continuous roller groups for the roller group of separating, and described roller group of separating forms the glazing calender of fibre-web machine.In this case, only can see part of the whole from the top of this machine position, wherein each roller group includes body frame and the roller group relevant with this body frame.Described roller group of separating or for example the glazing calender with 10 rollers of fibre-web machine can comprise two continuous roller groups, wherein this calender can principle according to the present invention be set to respect to this machine position: can see that the only 3m of described roller group is in the top of this machine position.
For the present invention, also have following feature: can shared hoisting frame or shared maintenance platform be set for described roller group of separating or described two continuous roller groups, described hoisting frame or maintenance platform be assemblied between the roller group in the described roller group of separating or the roller group in described continuous two roller groups between.In this case, especially the maintenance of roller and replacing become easier, the quantity of hoisting frame reduces, for example only need a hoisting frame or maintenance platform for two roller groups of separating or continuous roller group, thus, correspondingly reduce or reduce about 2m along machine direction or along the length overall of the fibre-web machine of the MD direction of fibre-web machine according to the quantity of hoisting frame.
Description of drawings
By case description the present invention, but is not to limit the invention to the example that is considered as the preferred embodiment example hereinafter with reference to appended accompanying drawing, this:
Fig. 1 is shown schematically in the side view according to support scheme of the present invention.
The specific embodiment
In Fig. 1 in the side view mode a kind of roller group A that separates of fibre-web machine, the support scheme of B are disclosed.In this example, the roller group of paper machine is the glazing calender that separates with 10 rollers, and in this calender, roller group A comprises 5 rollers, and roller group B also comprises 5 rollers.At first paper web W enters roller group A, and paper web W marches to the roll nip N around a plurality of deflector rolls downwards from the top, and described roll nip N is between overlapping felt wrapped roll interact with each other; Paper web W enters roller group B then, and paper web W upwards marches to roll nip N around a plurality of deflector rolls from the below, and described roll nip N is between the felt wrapped roll of overlapping influence each other.After the process calender, paper web is sent to taking-up equipment (reeling).
Disclosed as Fig. 1, each the roller group among described roller group A, the B includes body frame 10.For the load (being roller nip pressure) of adjusting press polish paper web W, at least two nethermost felt wrapped rolls of load cylinder (load cylinder) 6 in the vertical directions carrying.Alternatively, similarly load cylinder also can be arranged to act on uppermost felt wrapped roll, in this case, the load that described load can be by adjusting nethermost felt wrapped roll or the load of uppermost felt wrapped roll or the load of nethermost felt wrapped roll and uppermost felt wrapped roll are regulated.
Known ground, because the effect of gravity, upper calender can produce extra pressure to the bottom felt wrapped roll.Its result will cause roller nip pressure inhomogeneous, or down increase the roller nip pressure load.In order to address this problem, the device (it is not shown in Fig. 1) that inhomogeneous roller nip pressure that gravity is caused compensates can be set in the brace summer of felt wrapped roll.Can make the roller nip pressure on the calender distribute more even by this compensation arrangement.
Usually mean according to support scheme of the present invention and to be suitable for supporting the roller group that comprises body frame and at least two rollers.
Essential distinction as the accepted practice that adopts with tradition, according to basic design of the present invention, the body frame 10 of roller group A, B directly is fixed on the base 12 of horizontal machine beam 11 and fibre-web machine below, thus, described roller group is supported on the top of MP place, machine position or machine position MP, and wherein this fibre-web machine is paper machine in the embodiment in figure 1.According to a preferred embodiment of the invention, base 12 is dry concrete (stiff concrete) bases, its rigidity from having reduced material cost in essence and having improved body frame, in this case, this base can constitute the part of the body frame of described roller group.
In order to realize example of the present invention, typically make the roller group be positioned at the below of machine position MP at least in part usually.For this reason, below the MP of machine position, expand the hollow bulb (hollow) 13 that is useful on described roller group A, B.This hollow bulb can for example be the groove that is formed up in the engine house of base plate, and this groove forms machine position.When the glazing calender that separates (it is shown in Figure 1) with 10 rollers of paper machine is arranged in the hollow bulb 13, can see that calender is higher than the machine position, only be about 3m.
In order to minimize the structure length of fibre-web machine, preferably, support scheme according to the present invention is applied to the roller group, described roller group is such as the roller group A, the B that separate in Fig. 1 example, the roller group of wherein separating forms the glazing calender of paper machine.The same with the roller group of separating, described roller group can also comprise two continuous roller group A, B.Because the present invention, according to Fig. 1, shared hoisting frame or shared maintenance platform can be set then, described hoisting frame or maintenance platform are assemblied between the roller group in the described roller group of separating or between the roller group in the described continuous roller group.In this case, especially can be so that the maintenance of roller and replacing, and the quantity of minimizing hoisting frame, for example, only need a hoisting frame or maintenance platform for two roller groups of separating or two continuous roller groups, thus, reduce accordingly, in other words reduce about 2m along machine direction or along the total length of the fibre-web machine of the MD direction of fibre-web machine and the quantity of hoisting frame.
