Known ring flaker is proved to be to be fit in actual applications in principle.But the resharpen of blade causes high cost all the time.The present invention sets out thus.
Summary of the invention
Task of the present invention provides a kind of device that starts the type of putting forward, and it is simple in structure and can smooth and without problems sharpening and the especially blade of resharpen ring flaker.
In order to solve this task, the present invention proposes a kind of for coming sharpening by polishing processing, especially resharpen is for the device of the blade of the cutter ring of ring flaker, it comprises at least one sanding apparatus and at least one turntable, the cutter ring can be fixed on the described turntable, so that the cutter ring can rotate with respect to sanding apparatus keeping flat in the position of the axis with vertical orientation, described turntable and sanding apparatus are arranged on the oscillating table, this oscillating table is rotatably mounted on the frame around horizontal axis, is used for the cutter ring is turned to the Working position with vertical axis from the position that splits out with horizontal axis.
In this present invention at first from such understanding: it is particularly favourable processing under the flat condition that is splitting out the cutter ring outside the ring flaker.Sanding apparatus be placed into the cutter ring inside and for polish blade cutter ring for example continuously (lentamente) rotation.The advantage of the flatwise layout of cutter ring is the position that can guarantee that the cutter ring is stable, thus the distortion of avoiding the cutter ring in erectting orientation, only to occur because of gravity in simple mode, because the quality of cutter ring is usually greater than 1 ton.In addition, in keeping flat the position, can apply simply large propulsive force.That processes in keeping flat position (axis that namely has cutter ring vertical orientation) is also advantageous in that sanding apparatus can import the cutter ring from the top, thus abrasive particle in other words abrasive dust can discharge downwards simply.This preferably with the dry grinding mode, particularly preferably process by belt grinder.Therefore need not cooling medium required in the wet-milling preferred embodiment at this.
Therefore especially can process in simple especially mode by device of the present invention and be in the cutter ring that keeps flat in the orientation, because turntable and sanding apparatus are arranged on the oscillating table.In ring flaker with erect to arrange cutter ring that (axis that namely has horizontal orientation) install therefore can this erect be removed and be arranged to by device of the present invention, namely by self-sharpening machine of the present invention from ring flaker in the orientation on.The cutter ring is fixed on the turntable and therefore in the orientation of erectting and also is fixed on the oscillating table.Then therefore oscillating table rotation and cutter ring can change over to the Working position that keeps flat from the position that splits out of erectting.Because turntable and sanding apparatus can be fixed on the oscillating table, so but the whole system integrated overturn, thereby can begin glibly subsequently polishing processing.Therefore can process the cutter ring that is in the flatwise layout in economic especially mode by the present invention.
Preferred sanding apparatus can move at axial make progress with the footpath (with reference to the axis that is fixed on the cutter ring on the turntable) with respect to sanding apparatus with respect to turntable and/or turntable on the oscillating table.Therefore for example but stationary positioned is on turntable for the cutter ring, and sanding apparatus then can be positioned in the diverse location.Therefore sanding apparatus keeps flat middle one side at the cutter ring and can move in the axial direction, namely rise and descend, and the movement that can make progress in the footpath of cutter ring on the other hand.But also have in principle such replacement possibility: the cutter ring moves with respect to sander.
Structurally the present invention can realize in the following manner especially simply: at oscillating table the supporting slide is set, propelling drive apparatus can be mobile diametrically on oscillating table in other words by the feed drive unit for it.Preferably be provided in addition the holding device of sanding apparatus, this holding device is arranged on the supporting slide by lifting driving device.By the movement of holding device with respect to the supporting slide, sanding apparatus can move in the axial direction.Therefore preferably be provided for turntable rotating driving device, be used for oscillating table oscillatory gearing mechanism, be used for the lifting driving device of sanding apparatus and/or be used for the feed drive unit of sanding apparatus.They can be motor-type and/or hydraulic pressure and/or pneumatic drive units.
In category of the present invention, the polishing of cutter ring processing is carried out at turntable during " slowly " of cutter ring rotation, reciprocally move axially, for example reciprocally rise and descend at this sanding apparatus, thereby sanding apparatus moves along blade lengths.The feed campaign that the propelling that can wish is diametrically simultaneously wished in other words.Scheme can be at static each blade of middle processing of cutter ring as an alternative in category of the present invention.Therefore the cutter ring for example can be positioned in definite position and processes respective blade by propelling and lifting sanding apparatus afterwards.Then, the cutter ring can continue at a predetermined angle rotation and next blade is processed.What conform with especially in this embodiment purpose is that the cutter ring can be locked in definite angle position.For this reason suitablely be that turntable can be on oscillating table in the angle position of locking meaning in office.
By another suggestion of the present invention, described device has the blade propulsion plant blade extruding device in other words that extrudes in other words element with one or more blade propulsion elements, and by them, each blade can move with respect to the cutter ring.Known in principle, cutter holder is provided with suitable space, and by these spaces, executive component can act on blade from behind with same degree, thereby blade can be promoted towards cutter ring center position.Now the present invention suggestion is fixed on the extruding device (being the blade propulsion plant) (directly) that is provided with this extrusion element on the oscillating table.Therefore particularly preferably in turntable not only being set on the oscillating table and having the sanding apparatus of corresponding feed possibility, but also be fixedly installed extruding device.Whole system can be rotated along with oscillating table, thereby extruding device is with respect to turntable with always remain unchanged with respect to the relative position of fixing cutter ring thus.Therefore need not to carry out expensive adjusting work at every turn.Certainly the blade propulsion plant that is fixedly mounted on the oscillating table has movable propulsion element, and they can move and be applied on the blade with respect to oscillating table.
What this belonged to category of the present invention in principle be: blade is at first become flexible by for example unclamping trip bolt before being forced out.As be known in the art, can unclamp in principle clamping, propulsion blade and subsequently fastening clamping at this.But the present invention's suggestion in particularly preferred expansion scheme can be by the blade of extruding device propelling in cutter holder or on cutter holder in the situation of not unclamping clamping.Therefore no longer need to unclamp known in principle trip bolt.The present invention is from beyond thought understanding in this scheme, that is: the blade that can be simply advances ring flaker by the instrument that is fit to is in order to polish again, and need not to unclamp the clamping in cutter holder.Therefore in this scheme the present invention opened up one with the antipodal new way of known method and proposition: no longer unclamp and clamp and blade is pushed into the yardstick of hope in order to polish under the state of clamping again.Therefore need not require great effort again and unclamp fastening bolt and saved corresponding required cost of equipment, the again polishing of blade can and be carried out rapidly by the said apparatus low cost thus.Extrude element for this reason, for example extrude in bar stretches into tool rest with the meaning of drift the groove and blade is extruded forward the yardstick of hope.Extrude part for this reason and be provided with suitable drive unit.Can followingly operate at this: at first by the rotating gradually and pause and extrude subsequently stretching into of part of cutter ring, make all blades advance the yardstick of wishing.Cutter ring continuation rotation is wished after extruding blade distance and next blade can be pushed into.After advancing all blades, for example can in cutter ring slow circumvolve, polish in the manner described.
In addition the present invention suggestion is fixed one or more maintenance bars that move horizontally in the frame of sharpening device, and it is also referred to as and splits out bar and can move in the horizontal direction.Described maintenance bar is used for receiving the cutter ring of erectting and making it to move to oscillating table.The cutter ring for example is fed to the self-sharpening machine with the orientation of erectting on independent dolly.Keep there bar extensible, in order to receive the cutter ring from dolly.By keeping the travelling backwards of bar, the cutter ring moves in the self-sharpening machine.At first be in (axis with level) in the vertical orientation at this oscillating table, thereby oscillating table can receive the cutter ring of erectting (axis with level) in the orientation.Then the cutter ring is fixed on oscillating table and thus on the turntable, and can the cutter ring be changed in the Working position that keeps flat in the manner described by oscillating table subsequently.The characteristics of device are compact structures at this.
As mentioned above, the sharpening of blade can carry out with identical degree in the slow circumvolve of cutter ring continuously.This particularly is suitable for blade and should simply polishes by the situation of sharpening with tradition.But in category of the present invention, also there is optional possibility: in known mode own as blade polishing relief angle.Be single successively sharpening blade in the cutter ring is static to what this suited.This in description taken in conjunction with the accompanying drawings by exemplary illustration.
Preferably by pressing the in the manner described blade of sharpening cutter ring of device of the present invention.
But not only be suitable for the sharpening blade but also be suitable for sharpening scuff panel (" wearing and tearing boots ") by device of the present invention, and be to utilize same sanding apparatus.But suit blade is pushed back the rear of scuff panel inner surface, in order to can polish subsequently scuff panel for this reason.

The specific embodiment
Fig. 1 illustrates a kind of stock-removing machine, its embodiment for be used for cutting the chipper says or broken timber, in particular for making the ring flaker of wood shavings or similar material.In housing 1, on the one hand (outside) cutter ring 2 of rotation is set and is arranged on the other hand the fragmentation wheel 3 that rotates within the cutter ring.Cutter ring 2 and broken wheel 3 all drive by the axle that is fit to.At this details is not shown.Usually on the one hand cutter ring 2 and on the other hand fragmentation wheel 3 reverse rotations.Fig. 1 illustrates the ring flaker with housing of opening in front, thus especially visible inner cutter ring 2 and broken wheel 3.Timber is as discrete material, for example with the form charging of wood chip.Timber enters ring flaker inside and therefore arrive the inner space that forms in fragmentation wheel 3 by the feed well 4 of top and the transfer 5 of corresponding front.In Fig. 2, in the Local map mode cutter ring 2 that is in the processing unit (plant) zone in the state of splitting out is shown.Cutter ring 2 has two with the annular disk 2a of the spaced setting of axial distance, fixes many tool rest 2b between described annular disk.Can see that each tool rest 2b is furnished with blade 6 and is furnished with scuff panel 7 at opposite side in a side, scuff panel is also referred to as wearing and tearing boots 7.Scuff panel 7 is fixed in tangential orientation on the cutter ring inboard.Each scuff panel consists of the inner surface of cutter ring 2 with its inner surface 8.Blade 6 arranges with respect to scuff panel 7 with predetermined angle [alpha].Blade protrudes from respectively the inner surface 8 of scuff panel 7 with predetermined blade plussage between two adjacent scuff panels 7.The blade plussage refers to the blade plussage that adjusts for operation at this.Blade 6 is fixed on the cutter holder 9 replaceably at this.Trip bolt 10 is set for this reason, and by described trip bolt, blade 6 is clamped on the cutter holder.Cutter holder 9 for example can comprise holding plate and clamping plate.The blade 6 of cutter ring 2 must regularly be polished by sharpening in other words.Cutter ring 2 to be split out from the ring flaker according to Fig. 1 for this reason and load map 3 to 9 shown in processing unit (plant) 11 in.The vitals of processing unit (plant) 11 is sanding apparatus 12 and is turntable 13 on the other hand that the cutter ring that splits out is fixed on the turntable on the one hand, and so that cutter ring 2 can be along with rotating at turntable 13 in other words.In addition particularly importantly, sanding apparatus 12 can with respect to turntable 13 in other words cutter ring 2 fixed thereon axially and the footpath upwards mobile, or rather with respect to the axis A of cutter ring axially and the footpath upwards mobile.
Fig. 3 to 6 illustrates the processing unit (plant) 11 that is in the difference in functionality position.Background is as follows: cutter ring 2 is split out from ring flaker in being in the layout of setting and then is being in the layout that keeps flat and processed in processing unit (plant) 11.In order to realize this point in simple mode, turntable 13 and sanding apparatus 12 are arranged on the oscillating table 24, described oscillating table 24 can be rotatably fixed on the frame around horizontal axis 29, in order to cutter ring 2 is turned to the position in the Working position with vertical axis from having splitting out of horizontal axis.Structure and action principle with system of oscillating table can find out that by paired observation Fig. 3 to 6 wherein, Fig. 6 illustrates the processing unit (plant) 11 with the cutter ring 2 that is in the Working position that keeps flat, in this processing unit (plant) by sanding apparatus 12 processing of polishing.
At first, the cutter ring is from according to being split out the ring flaker of Fig. 1 and shifting out from ring flaker by the visible bar 32 that splits out in the figure.The cutter ring can for example be fed to processing unit (plant) 11 by independent (unshowned) travelling bogie therefrom.
Fig. 3 illustrates the processing unit (plant) 11 that at first has horizontally disposed oscillating table 24, and cutter ring 2 is not installed.Processing unit (plant) at first changes over to second POF shown in Figure 4 from this first POF, and this moment, oscillating table was in this vertical setting.In the second POF, can receive cutter ring 2 from unshowned travelling bogie or analog.Therefore for this reason, processing unit (plant) has two maintenance bars 31 in frame 14, and they can move into and shift out and can move in the horizontal direction, thereby keeps bar can receive the cutter ring of setting and make it to move to oscillating table 24.This when the paired observation Figure 4 and 5 as seen.Therefore, cutter ring 2 processed device 11 in the layout of erectting receives and is fixed on subsequently on the turntable 13.For this reason, turntable 13 has a plurality of retaining elements 30.After cutter ring 2 is fixed on the turntable 13, oscillating table 24 can rotate around horizontal axis 29 by oscillatory gearing mechanism 25, so that oscillating table 24 changes over to the position of level from vertical position and therefore cutter ring 2 changes the position that keeps flat the axis vertical orientation of cutter ring 2 in the position that this keeps flat over to from the position of erectting.This paired observation Fig. 5 and 6 o'clock as seen.Therefore Fig. 6 illustrates the processing unit (plant) 11 with the cutter ring 2 that is in the Working position, and cutter ring 2 is in the layout that keeps flat of the axis A with vertical orientation in Working position.Oscillating table is provided with one or more hydraulic cylinders in this embodiment as fluid pressure drive device, and described hydraulic cylinder acts on oscillating table by leverage.
At this particularly importantly, sanding apparatus 12 is arranged on the oscillating table 24, but can be mobile at axially and directly make progress (with respect to the axis A that is fixed on the cutter ring on the turntable) with respect to turntable 13.Therefore after cutter ring 2 was positioned on the turntable 13 with position shown in Figure 6, sanding apparatus 12 can descend at axial Y, thereby sanding apparatus sinks in the cutter ring 2.The polishing processing of blade 6 is preferably undertaken by the slow circumvolve of cutter ring 2 around sanding apparatus 12 when sanding apparatus 12 operation.By controlling polishing processing with respect to cutter ring 2 positioning grinding device 12 on X radially.This structurally realizes in the following manner in the embodiment shown: at oscillating table 24 supporting slide 15 is set, supporting slide 15 can with respect to frame and therefore with respect to oscillating table 24 at X radially mobile and therefore location.In this embodiment, linear guidance device 16 is set for this reason.Be fixed for the holding device 17 of sanding apparatus at supporting slide 15, and so that this holding device 17 can be in that axially Y be mobile on supporting slide 15.---being fixed with again sanding apparatus 12 on it---can rise and descend to this means holding device 17.The linear guidance device 18 of vertical orientation is set between supporting slide 15 and holding device 17 for this reason.For turntable 13 arranges the rotating driving device 19 that only signal shows.Sanding apparatus 12 is configured to the belt sanding device.This belt sanding device has for the polishing drive unit 21 that drives abrasive band 20.Sanding apparatus 12 in other words its holding device 17 can move, for example rise and descend by lifting driving device 22 on supporting slide 15.In addition, in other words propelling drive apparatus 23 of feed that signal shows only can be set, by this feed propelling drive apparatus in other words, sanding apparatus 12 supports slide 15 in other words can be in that radially X be mobile.Can see that in addition oscillating table 24 can rotate around pivot center 29 by oscillatory gearing mechanism 25.
Can find out also in the accompanying drawings that in addition be fixed for the extruding device 26 of blade at oscillating table 24, it has a plurality of extrusion elements 27.This extruding device is called as blade propulsion plant 26.Each blade of cutter ring 2 can be advanced the yardstick of wishing by the extrusion element 27 that for example can be configured to extrude bar and extrude in other words drift, because advance the yardstick of regulation to conform with purpose in the polishing first being processed by propulsion plant 26 on blade.Propulsion plant 26 has two configurations to the blade propelling drive apparatus 28 of pushing ram 27 for this reason.Each pushing ram passes this groove that just arranges by tool rest from behind with same degree, thereby pushing ram is applied on the blade from the blade back side.At this advantageously, propulsion plant 26 regularly (but in the necessary situation adjustable ground) be arranged on the oscillating table.Therefore on the one hand have for the turntable 13 of the fixing point 30 of cutter ring and on the other hand propulsion plant 26 be fixed on oscillating table 24 in fixing predetermined layout each other, thereby their relative position does not especially change when oscillating table 24 rotation.
Preferred propulsion plant in other words extruding device 26 is being worked in the situation of not unclamping trip bolt in the situation of the clamping of not unclamping blade and therefore.Thereby can be continuous by the drive unit 28(that extrudes element by extruding element 27 in the situation of not unclamping clamping) propulsion blade.Send into cutter ring 2 in the definite position by rotating driving device for this reason and advance single blade.The cutter ring can determine that angle continues rotation and next blade is pushed into subsequently.Preferably at first advance all blades with the yardstick of determining.Subsequently can be in cutter ring rotation by the processing of polishing of 12 pairs of all blades of sanding apparatus.It is important in this that, during polishing processing, can guarantee the blade plussage of wishing by suitable control sanding apparatus and especially positioning grinding device.Therefore the above-mentioned propelling of blade need not to enter into the exact position, and only needs blade is advanced certain smallest dimension, because the blade plussage of wishing just produces after polishing processing.
Oscillating table 24 can turn in the position shown in Figure 5 and cutter ring 2 is removed and reinstalled in the ring flaker again after polishing processing.
Yet, replace the aforesaid operations method also can single successively propulsion blade in category of the present invention and directly with its sharpening.Therefore not processing in the rotation of cutter ring in this scheme, but the processing of in the cutter ring is static, polishing.This is particularly suitable when blade should be polished relief angle.For this reason referring to Figure 10 a and 10b.Figure 10 a at first illustrates the blade 6 that is in the polishing position, and the milling tools radius is R.The location of sanding apparatus represents by the position line 33.Therefore the rotation of cutter ring and blade can produce the geometry shown in Figure 10 a in the other process of sanding apparatus in before described processing.Relief angle is 0 in the case.
Relative therewith, Figure 10 b illustrates the situation of relief angle polishing.In Figure 10 b, at first mark for the reference position 33 without the polishing of relief angle.Sanding apparatus is arranged in the position identical with Figure 10 a.Again mark radius R.In the comparative observation of Figure 10 a and Figure 10 b as seen, the cutter ring in according to the situation of Figure 10 b from different according to the location among Figure 10 a, because the axis of the blade that specifically will process and sanding apparatus is located with being misplaced.The blade position that is used for the polishing relief angle represents with the position line 34.The radius R of sanding apparatus is marked again.By be misplaced can polish the now relief angle of blade 6 with respect to sanding apparatus 12.But this carries out in the cutter ring is static.At first only advance blade to be polished, this is shown in Figure 10 b.Therefore the cutter ring does not rotate, and only is that sanding apparatus 12 moves around in the axial direction.The radius of sanding apparatus 12 is reflected in the blade 6, produces the relief angle F shown in Fig. 6 b at this, and this relief angle is 4 ° in current embodiment.Therefore this polishing processing can not be carried out in the rotation of cutter ring, but by above-mentioned blade propulsion plant each blade of single propelling and subsequently by shown in " being misplaced " polishing blade.This also realizes by following manner: described blade propulsion plant 26 adjustable grounds are fixed on the oscillating table, because the blade that will advance must be in the position that is misplaced when relief angle is polished, to such an extent as to the blade propulsion plant also must differently be located.This realizes by suitable adjusting.After regulating end, blade propulsion plant 26 is fixed on the oscillating table by " position regularly " again, and the relative position between cutter ring and the blade propulsion plant 26 does not change when oscillating table rotates thus.Therefore can generally use by device of the present invention, for example also be used for the relief angle polishing.Part by changing sanding apparatus, for example grinding stone or the emery wheel of the preferred belt grinder that uses can produce different shapes or radius.
