The invention relates to a grinding device for Söhelbeiischneldiaaaahinen with a rotatable circular knife \ with a boat immersed to pick up the son's goods, back and forth from which the sole is a device, this having a sole and a peeling disc, the axes of which are inclined to each other and are arranged offset and the rotating sharks of the sharpening disk are inclined to the Meaeere disk <

BAO ORIGINAL 809810/0082

There are already grinding devices known for Scheibenschneldmaschinen in which the grinding apparatus wegnehnter attached to the back and herbewegliohen Materialauflagesohlitten was ο Ee eind while two slices involved in the grinding process, the actual grinding wheel for temples of the circular knife and honing nämlieh to remove the Schleifgpafceβ _P After the sole ridge of the circular knife was attached to the grinder by a? rotatable _{extractor disc removed 9,} which for this purpose was resiliently mounted and adjustable in axial direction by finger pressure ₀

In contrast, the present invention is characterized in that an organ is present; the sharpening wheel and the honing wheel connects with each other in such a way that a movement of the sharpening disk approximately in the direction of its axis causes a movement of the honing disk that is dependent on it, transversely to the plane of the knife.

This makes it possible to make the grinding of circular knives of Scheibenachneidmaschinen significantly simplify and by the dexterity, friendliness of the operators largely independent since the delivery of the & m burr occurs remove honing automatically and the force with which it is pressed against the knife, is no longer at the discretion of the operator, but can be set by the manufacturer to precisely defined, optimal values - by choosing the appropriate springs - the risk of accidents is also reduced, as you no longer get into the immediate danger area by dragging the circle with the bands "

809810/0082

The actual grinding device has two grinding organs, namely, the upper honing disk 25 shown in FIG. 5 and the in Pigο 6 shown, lower actual sharpening disk 26, whose The axes of rotation run horizontally and form an angle with one another.

The extractor disk 25 is fastened to a bush 3Q by means of a nut 31, which is rotatably and axially displaceably mounted with its guide pin 32 located in the middle of the bushing 30 has an annular cavity 33 "which receives a compression spring 34, which is supported on the one hand on the base of this cavity 33 and on the other hand on the housing 10 and pushes the puller disk 25 in the direction of arrow A = the bushing 30 is supported according to FIG. 5 with its tip 27 against a housing 10 fixed to the leaf spring 28 from whose spring stiffness is greater than that of the spring, d _o h _o the spring 34 is weaker than the spring 28ο

The in Flg. 6 shown Schüfscheibe 26 is also on a bush 35 attached by means of a cutter 36 · The guide bolt 37 is axially displaceable and rotatable in the 18-30 °, preferably 23 ° obliquely but perpendicular to the knife plane and fixed in the housing 11. At its free lower end, the hollow axle 38 has a radial extension 40 on which a compression spring 41 is applied. The other

8098.10 / 0082

The end of the spring 41 is supported against an elastic retaining ring 42 which is inserted into a radial recess 43 in the bushing. The spring 41 pushes the sharpening disk 26 in the direction of arrows B. In the rest position, the face of the Hollow axle 38 at the bottom of the bore 40 at «The tip 44 touches the leaf spring 28 in a similar way to the tip 27 the AlMSiehschelbe.

Daa housing 10 is against the Ansohlagplatte 3 through a Cover plate 46 completed; However, it remains open on its upper side and towards the knife, so that the knife can get into the inside of the housing during grinding and there with the two Sole discs 25 and 26 can come into contact with this opening can be covered by a slider or a hood.

On the side of the cover plate 46 let in the grinding wheel housing there is an anchor plate 50 which is intended to engage in a hat 51 in the anchor plate 3 in order to counteract one BolEen 52 to lie against, (Figo 15) »when the end position has been reached.

So that the material support table 2 only in the two end positions of the slider 8 »nloht in intermediate positions - what a Damage to the knife or the grinding device - is possible, safety precautions may be taken, for example by a attached to the slide 8, (not shown neter) Bolaen in grooves of a stationary housing partea-H3-ingreT? tV

13 and 14 show an embodiment variant "Instead of a slider 8 with a hand lever 14 where the grinding wheel housing 10 is a bolt 58 &" ■ a horizontal axis pivotably mounted. This bolt 58 is arranged on the upper part of the vertical pool 2a . In this housing 10, which is open on one side, is the Abziehacheibe 25 and the sharpening disk26, which are each rotatably held in bearing eyes 60? similarly as in the embodiments gemäee FIGS. 5 and 6 of the case istο Pie two discs 25, 26 are yieldable elastically through a common _f leaf spring supported 28 at its one end so that axial movement of the disc 26 also to the Disk 25 transmits "The spring 28 is rigidly attached to the foot of the housing 10 by a screw 61" to hold the housing 10 either in the working position, according to the position shown in solid lines in FIG. 14, or in the rest position. which latter is indicated in FIG. 10 by broken lines, a locking pin 62 is provided, which can be inserted either into the opening 63 or 64 and thus hold the housing 10 in its respective desired position

Ee would also be conceivable that the housing would be made pivotable about a horizontal instead of Drehaxe to a vertical or slanting axis 10 ₀

The function of the grinding device is based on the following 7 to 12 explained »

809810/0082

The material support isoh 2 is initially pulled back to its rearmost position, near the rotary knob 4, so that the housing 10 is outside the area of the circular knife * and the grinding wheels _{assume the position shown in Mg 0} 7 and 8 with respect to the mesa Stop plate 3 by means of de.?; The rotary knob 4 is brought into its outermost position furthest away from the knife 1, shown in phantom in PIg ₀ 2. As soon as the machine is prepared so far, the actual grinding device 11 can be moved in the direction of arrow C * which was done by pivoting the plane 14. The sharpening and honing disks 25, 26 are still in their Huholage described in FIGS. 5 and 6, in between the MessoTfläohe and the end face of the draw-off plate 25 b, a distance (Figo 9) mm as in the order of magnitude of 1 is present ₀

As for the proper cutting of the material to be cut the distance a by periodically readjusting the stop plate 3 is kept approximately constant, the stop 52 also moves with it, so that the relative position of the grinding wheels 25, 26 with regard to the cutting edge of the knife for a new as well as a worn knife with a smaller diameter for grinding ~ process is approximately retained "

By adjusting the slide 8 in the direction of the arrow P, the opening bolt 50 enters the hats 51 of the stop plate 3 on »When moving the material support cover 2 by hand

80 98 10/0082.

In the direction of arrow D (Figs. 9 and 10) the grinding device 11 approaches the knife 1 and initially comes into contact there with the inclined sharpening disk 26 the stop pin 50 of the housing IO is in contact with the pin 52 of the stop plate (Pig, 11 and 15) ο The knife 1 presses the tip 44 of the sharpening disk 26 against the leaf spring 28, which is thus pressed in the direction opposite to the arrow B. leaf spring 28 is 25 brought the applied also against the same leaf spring Abziehschelbe to rest against the knife, d _o h ₀ of the previously occupied distance b of the honing wheel 25 opposite the blade 1 falls away and the Abziehschelbe removes the produced during grinding burr on the blade 1,

Once the knife sharpened in this way iet _s is the! Table 2 withdrawn by hand into the original position and the discs 25 and 26 return to their rest position under the restoring force of the leaf spring 28th Then, the lever 14 is so-zurückversohwcnkty that the slider 8 and with it the grinder 11 ₀ 3 represented by the spring 16 shown in Fig, original rest position are moved back ,. The leather 16 is stronger than along the Peder 41 and the leaf spring 28 so that the slide is not displaced during grinding 8 automatically against the knife towards ο

A variant of the grinding device consists in that the tip 27 of the honing disk 25 is supported against a fixed counter-bearing on the Deok plate 46 so that it is not axially

809810/0082:. - ■ V.

"The compression spring 41 of the sharpening disk 26 is then made somewhat stronger than the compression spring 3.6 of the slide" When the knife 1 is sharpened, the slide becomes under the action of the inclined sharpening disc 26 moved in the direction of arrow P towards the knife 1 until the honing disk 25 comes into contact with it and then removes the sole ridge,

It would also be conceivable for the grinding device to be attached to the material support slide in a way that is likely to happen. In addition, the son's knife 1 and thus the material support table could be arranged in an inclined position (e.g. 45 ° to the horizontal). It would also be possible to dispense _e in erstbescf ~ rlebenen Varianif the spring 41. A further AuBführungsvarian "te would be that a pivotable about an axis lever lst present instead of a leaf spring 28 _f by means of a spring against the tips 27 and 44 is pressed o

In the Aueführungsform according to FIGS "13 and 14, the basic operation is the same as the embodiment of Fig. 7 - 12 _o Instead of geradliniegen displacement of the grinding device in and outside the area of diameter" occurs in the embodiment gemäes Figures " , 13 and a pivoting movement of the housing a IO about the bolt 58 as hearing ·; zontal axis of rotation ο
