Advantageously, milling drum has grinding tool or grinding assembly and smoothing unit, and the grinding tool or grinding are total
Into with least one brush with grinding bristle.Smoothing unit is the functional unit in milling drum, and the functional unit is for example
In the special operational mode of milling drum be responsible for again establish grinding tool, especially brush roll axiality (Rundlauf) and directly
Dimension (Geradheit).The special operational mode for example can be in journey that is pre-determining and being stored in electronic data memory
The form of sequence is present, and the electronic controller of milling drum can read and implement the program.Therefore, the grinding according to the present invention is passed through
Machine only also needs to remove real grinding tool, especially brush roll from milling drum on rare occasions.This is only should
Just needs when brush roll is changed completely.If it is determined that：The extruding force of grinding tool is no longer on the width of brush roll or each
Consistently produced on the spatially extended yardstick of brush, then for example manually trigger the special operational mode of milling drum.In the situation
Under, establish the axiality and linearity of brush roll again by smoothing unit.This can occur within a few minutes so that by being somebody's turn to do
After period, when having run the program being for example stored in electronic data memory, milling drum can fully make again
With and almost optimal grinding result is provided.
Advantageously, smoothing unit has at least one smoothing unit, for shortening at least a portion of grinding bristle.
When being ground by milling drum, each grinding bristle of grinding tool compared to other parts more strongly by
Load and be especially more strongly lost so that the grinding bristle is compared to the mill being for example arranged on the edge of grinding tool
Cutting bristle has shorter length.In order to ensure optimal grinding result, advantageously make grinding brush, especially brush roll now
All grinding bristles shorten to a length, to realize uniform grinding result.It can certainly be produced by smoothing unit
Raw each grinding bristle uneven length each other, its mode is to shorten the grinding bristle in the different zones of grinding tool
To different length, as long as this is desired and favourable.
Smooth instrument for example can be made up of multiple cutting elements, and the cutting element is for example on the width of grinding tool
Arrange and therefore can shorten the grinding bristle of grinding device simultaneously over the entire width.Here, smooth instrument can construct
For big cutting element, such as sword extended over the entire width or cut, or by multiple different, units for being arranged side by side
Part forms, and the difference that then can adjust grinding bristle on the different positions of grinding tool by the unit piece is long
Degree.
Instead of this, it has proved that advantageously：Smooth instrument is along the direction being transversely to the conveying direction movably cloth
Put.Smooth instrument can be spatially small in itself and therefore be constructed with relatively small deadweight so that in this grinding
To be that the equipment cost that smoothing unit is run is substantially reduced in machine.Especially in the case of brush roll advantageously, smoothing unit
Can be along direction (i.e. in the milling drum from left to right and in turn) motion being transversely to the conveying direction, and it is possible thereby to reach
To any part on the width of brush roll., can be in this way by brush roll because brush roll can be placed in rotation originally
All bristles shorten to desired length.
Preferably, at least one grinding tool and/or smooth tool height are adjustably arranged.Multiple known
In milling drum, grinding tool was Height Adjustable originally, so that the spacing between grinding tool and conveying device can be variable
Ground configuration, and thus it is adaptable to the workpiece to be processed of different-thickness.In this case advantageously, smooth instrument construction
To be unadjustable relative to the height of conveying device so that the height regulation of grinding tool is also resulted in grinding tool and smooth
The change of spacing between instrument.However smooth instrument can certainly height adjustable save land construction, as long as grinding tool
Need to adjust independently of one another in terms of height with smooth instrument.It only can just change spacing in this way and thus adjust
Save the length that can be shortened to by smooth instrument.
Preferably, grinding tool has multiple disc brushes, and the disc brush is turned round along revolution profile, wherein, described at least one
Individual smooth instrument is in conveying device arranged alongside.In the case of grinding tool has brush roll, smooth instrument is above the brush roll
Arrangement prove it is favourable because bristle points to the direction in itself in the brush of rotation.But if using disc brush, situation is
Different.In disc brush, general all grinding bristles all point to the direction of workpiece, and the rotation that disc brush is rotated about it or pivoted
Transporting flat of the shaft axis perpendicular to conveying device.It is also possible that smooth instrument is arranged in above disc brush in the configuration.
In this case, being orientated and making the grinding of disc brush for disc brush must be changed in the case of smooth special operational mode is implemented
Bristle is orientated towards the direction of smooth instrument.Although this is possible, cause improve utensil in terms of and technical elements
Cost.
Simpler solution is possible in situations below in structure：Except the rotation around its rotation axis it
Also also moved outside in the disc brush of revolution profile upper rotary in the region beside conveying device so that the following of revolution profile be present
Section, the grinding bristle of disc brush and disc brush will not contact with the workpiece in conveying device in the section.For example turning round
In region where the turning point of profile and turning part, can by it is particularly simple and save position and thus in technology
The mode of upper consuming arranges at least one smooth instrument.Advantageously, multiple smooth instruments are arranged in this case defeated
Send the both sides of device.
In preferable configuration, milling drum has the measurement of length device for being used for measuring grinding bristle.This for example can be with
Without touching, occur especially by grating or by pressure or touch sensor, the pressure or touch sensor measurement：It is determined that
Point whether the grinding bristles contact also with revolution.Here also proved advantageously, measurement apparatus is provided for measuring
The length of grinding brush on the different parts of grinding tool.This means especially that, can measure on the width of grinding tool
The length of grinding bristle on diverse location.Milling drum also has electric controller, and the electric controller is provided for, when different bristles
Between length difference when exceeding the limiting value of pre-determining, make smooth instrumental purpose in grinding bristle and shorten in this way firm
Hair.If electric controller is for example determined due to the measurement result of measurement apparatus：In the length of the bristle of the intermediate region of grinding brush
Length difference between the length of the bristle in the exterior lateral area of grinding brush exceedes the limiting value of pre-determining, then electric controller can
With the smooth operational mode of turn on automatically or it is allowed to come into force, and therefore causes smooth instrumental purpose to be ground bristle in corresponding,
So that the length difference between each bristle reduces or it is become desired yardstick.Instead of this, electric controller also may be used
With triggering display or alert device so that the operator of milling drum recognizes the need for shortening grinding bristle.
Advantageously, the limiting value of pre-determining depends on the length of grinding brush.If grinding brush is relatively short, because should
Grinding brush for example repeatedly shortens, then significant can select the limiting value of pre-determining relatively smallly, to realize
Relative length chang keeps small as far as possible.But if the length of brush is still relatively large, such as it is encased in milling drum newly
In brush roll in the case of, then can endure larger length difference completely.
