Background technology
This milling drum is by for a long time known in the art and be used for different surfaces.It is known that pass through this grinding
Instrument, brush or disc brush are for example ground to process wood surface or metal surface and thereby for example enter hardware in terms of seamed edge
Row deburring and rounding cause visually attractive skin effect in workpiece surface.Especially using grinding brush
When, grinding brush extends on the whole width of conveying device mostly, and the conveying device for example can be conveyer belt.To be processed
Workpiece is most and does not adapt to the width of conveying device, but has extension yardstick in this direction, and the extension yardstick is less than defeated
Send the extension yardstick of device and thereby again smaller than grinding brush width.This is not undoubtedly it is meant that in grinding workpiece surface, brush is
All grinding bristles are all formed with workpiece and contacted.On the width of grinding tool, grinding tool is especially in the middle region
Bear the load stronger than edge region mostly.
By following demand known in the art：Suppression can cause the effect worn more by force of grinding tool in the middle region
Should, its mode is, for example, and workpiece to be ground is passed through into milling drum in different position guiding so that even if the brush by negative
The small grinding bristle of lotus can also be formed with workpiece surface and contacted.But still grinding tool occurs and is especially ground the random of brush
The abrasion of rule.
But in order to which desired pattern is ground in workpiece surface or just in order to avoid specific grinding pattern and produced
The raw surface for being configured with grinding pattern as few as possible, it is favourable or be even necessary that：The mill that grinding bristle contacts with surface
It is in time and spatially constant to cut pressure.Otherwise, the load of the varying strength suffered by workpiece surface can cause：No
Uniform grinding vestige can be produced on the surface.Such as the deburring of the seamed edge of metal works or the prerequisite of rounding also exist
In, grinding tool act on workpiece surface extruding force be not only it is known and repeatable, and especially in time and
It is spatially constant.It will thus be brushed now after certain operation duration in grinding or the grinding tool of disc brush form be by being ground

The content of the invention
The task of the present invention is, so improves milling drum so that its can efficiently use and with it is few static when
Between, while grinding tool can use for a long time as far as possible.
The present invention solves the task, the feature of the milling drum by the milling drum of preamble according to claim 1
It is that it has smoothing unit.
Smoothing unit is the functional unit in milling drum, and the functional unit is for example in the specific operation mould of one kind of milling drum
It is used for the axiality (Rundlauf) and linearity (Geradheit) for re-establishing grinding tool, especially brush roll in formula.It is this
Specific operational mode for example can by pre-determining and exist in the form of the program that is stored in electronic data memory, the journey
The electronic controller that sequence can be ground machine is obtained and implemented.Thus by according to the present invention milling drum only also in rare occasion
Lower needs are removed real grinding tool, especially brush roll by milling drum.Only when brush roll should be changed completely, this is only necessity
's.If it is determined that：The extruding force of grinding tool constructs no longer on the width of brush roll or on the spatially extended yardstick of each disc brush
To be constant, then the specific run pattern of milling drum is for example manually triggered.In this case, brush is re-established by smoothing unit
The axiality and linearity of roller.This can occur in several minutes so that after that period of time, when being for example stored in electronic data
When program in memory has been run, milling drum is entirely capable of using and providing the grinding result of near optimal again.
Advantageously, smoothing unit has at least one smooth instrument, for shortening at least a portion being ground in bristle.
When being ground with milling drum, some grinding bristles of grinding tool compared with other by stronger load simultaneously
And especially wear strongly so that the grinding bristle Phase Proportion at edge of these grinding bristles with being for example arranged in grinding tool
As having shorter length.In order to can guarantee that optimal grinding result, will advantageously all of brush, especially brush roll be ground now
Grinding bristle shorten to a length, to realize uniform grinding result.Certainly if it is desire to and it is favourable if, can also lead to
The uneven length that smoothing unit produces each grinding bristle is crossed, its mode is, by the grinding in the different zones of grinding tool
Bristle shortens to different length.
Smooth instrument for example may include multiple cutting elements, and they are for example arranged on the width of grinding tool and thereby energy
The grinding bristle of grinding tool is shortened simultaneously over the entire width.Here, smooth instrument can be configured to big cutting element, such as
The sword that extends over the entire width is cut, or including multiple different, unit pieces for being arranged side by side, can ground by them
Cut the different length that grinding bristle is produced at the different parts of instrument.
Instead of this, it has therefore proved that for advantageously, smooth instrument movably cloth on the direction being transversely to the conveying direction
Put.Smooth instrument itself can construct spatially smallly and thereby with smaller from important place so that be in this milling drum
The equipment of smoothing unit operation, which expends, to be substantially reduced.Especially in the case of brush roll advantageously, smoothing unit is perpendicular to defeated
Send on the direction in direction, i.e., can from left to right and in turn move and thereby can be reached on the width of brush roll in milling drum
Each position.Because brush roll can be natively placed in rotation, all bristles of brush roll can be shortened to by this way
Desired length.

Diverse location at measurement grinding bristle length.Milling drum also has electric controller, and the electric controller is provided for when difference
Bristle between length difference exceed pre-determining boundary value when make smooth instrument with grinding bristle formed interaction and lead to
This mode is crossed to shorten bristle.If measurement result of the electric controller based on measurement apparatus for example determines：Grinding brush middle area
Length difference between bristle in domain and the bristle in the perimeter of grinding brush exceedes the boundary value of pre-determining, then electric controller
It automatically can open or perform smooth operational mode and thereby for making smooth instrument form phase interaction with corresponding grinding bristle
