Device for the production of granulates

The invention concerns a device for the production of granulates from a Kunststoffoder rubber course, with which the granulates particles are separately in a processing step on the basis of the longitudinal folds of the course progressively against the center of the course or against the center of a number of width section in each case along two for instance lips running in Längsund transverse direction of the course separable and which a Zuführtisch for a Kunststoffoder rubber course exhibits and on a cylindrical rotor opposite a orts£esten measurer individual gumption tool tightness arranged next to each other, whereby the cutting tools at the rotor are arranged for the center of the lateral surface of the rotor or for the center of individual BreitenabschILitte the same along one or several pairs of gegenläuf'xger spirals, whereby each individual cutting tool in each case exhibits a cut running in Längsund transverse direction for supply direction. With one from the USA patent specification Nr.2, 655.213 admitted, genericmoderately used device is in the form of steps the stationary knife as Gegenmesser for the cutting tools. trained. Equally the rotor is not cylindrical, but the form according to Gegenmessers stu£en£örmig trained, so that the distance is of various sizes dec individual gumption tool tightness of the engine axle. A similar device is in franz. Patent specification Nr.l.100.491 described. By means of these before-well-known devices the granulates particles are reduced from the course. Hiezu must be very high the driving power of the rotor, into the rotor storage arrives also strong impacts and due to these strong impacts of the Sclmeidwerkzeuge to become these very rapidly blunt, so that they must be immediately replaced. Apart from the high achievement expenditure necessary for such devices - for the treatment of one about 50 cm broad course one needs an achievement granulates suitable by approximately 25 PSgeht already after few revolutions of the rotor the exact fit between the cutting tools of the rotor and the Gegenmesser, necessary for accomplishing, lost; the continuity of the processing procedure comes can not be ensured to operational disturbances and. The moreover a change of the play between the cutting tools and the Gegenmesser can occur with the different heating up of the rotor and the Gegenmessers regularly entering with such devices, what leads in the ExtremfaU to a damage of the cutting tools and/or the Gegenmessers. The invention is the basis the task to repair the above-described lack of the before-well-known devices of the initially designated kind and to make a soft cutting possible of the granulates particles at optimally small achievement expenditure, whereby the wear of the cutting tools within moderate borders holds itself and is reliably protected the continuity of the processing procedure. This task is solved according to the most substantial ErFmdungsmerkmal thereby that the two cuts of each individual cutting tool are bent arranged in direction of rotation of the rotor seen against the Zuführtisch in each case and that the Gegenmesser is straight-lined trained. By it one that the individual granulates particles are cut out along two, with one another an angle of including lips from the course, reaches in each case u.zw in an individual processing step for each individual particle. The employment of the cutting tools takes place thus not suddenly, but continuously; accordingly there is no shock loadings leading to a rapid wear of the cutting tools and/or the rotor, the achievement expenditure and the wear is small, likewise the heat development. A further advantage consists also of that the gemdlinig trained Gegenmesser can be reground easily and besides by different heating up and deformation of the longing oath tools and/or the Gegenraessers arising problems does not let arise. From the arrangement of the cutting tools on the extent of the rotor it results that always only few cutting tools at the same time arrive with the Materialbahn at the interference, whereby the power requirement for the drive of the rotor is also reduced. Since all gumption tool tightness possess the same kerf width and a straight-lined passing cut possesses the Gegenmesser, also the Nachschleffen is extremely simply feasible and the rotor can be laid out easily for very broad Materialbahnen. Thus that only in each case two cutting tools of the rotor and/or two gumption tool tightness of each width section of the rotor are used at the same time, and furthermore thus that the cuts of these tools are not so trained and arranged that they set in each case at the beginning of a cut with their intersection, exist a danger that the piece of the Materialbahn freely before-rising up over the edge of the Gegenmessers is downward forced away with the cutting process. After a preferential execution form of the Erflndungsgegenstandes hiezu the two cuts are bent toward to their common intersection, whereby the intersection in direction of rotation of the rotor exhibits seen opposite dern Zuführtisch the shortest distance in each case. Appropriately the free end of the longitudinal cut in direction of rotation of the rotor exhibits the shortest distance opposite the Zuf'ührtisch, so that favourable-proves there in the intersection of the cutting edges a sharp point forms. A remark example of the invention article is described below on the basis the designs, u.zw shows the Fig.1 a side view and/or partly a cut of the erf'mdungsgemäßen device, the Fig.2 shows this device from right, also partly on average, the Fig.3 to 5 represents a schematic front view, side view and/or a plan view of a cutting tool and the Fig.6 illustrates a gumption pattern. The device represented in the Fig.1 and 2 possesses a support frame --10--, on a flat, horizontal Zuführtisch --11-- is arranged, over the one by cheeks --36-- laterally led plastic sheet --12-- by means of promotion rollers --! 3, 14-- against one with cutting tools occupied cylindrical rotor --15-- is adjustable, which is still more near described below. The Zuf'ührtisch --11-- and the rotor --15-- are by means of not represented organs in purchase to each other, u.zw. tangential to the rotor, adjustable. At that the rotor --15-- turned end of the Zuführtisches --11-- is ela itself over the whole width of the rotor extending stationary knife as Gegenmesser --16-- for the cutting tools arranged, that diagonally upward arranged by means of an attachment organ --17-- and screws --18-- in desired in each case situation is fastenable. To the drive of the rotor ---15-- is an engine ---19-- by means of drive belts --20-- attached to the motor shaft. The promotion roller --13-- becomes by means of a further belt --23-- of an engine --21-- over one the regulation of the Vorschuhgeschwindigkeit of the course --12-- serving governor --22-- propelled, while the promotion roller --14-- as Riemenspannro! IE is trained. The distance between the promotion rollers --13 and 14-- is adjustable in actually well-known way. To the regulation of the tension of the belts --20-- is the engine --19-- --24-- tiltable stored and in situation by means of a screw bolt, adjusted in each case --25-- ascertainable, against what the engine --21-- by means of a screw bolt --26-- on its base plate adjustably and by means of screw bolts --27--, which extend by Ausnebmungen of the base plate, can be recognized. Oberh1 lb the rotor --15-- is a turnable protection hood --28-- attached and from the area underneath the rotor --15-- a gutter leads --29-- from the housing of the device out. The rotor --15-- carries on a wave --30-- in actually well-known way a number of circular disks arranged next to each other --31--, at their extent from Fig.3 to 5 evident, preferably from HartmetaU existing and in the same Breke as the disks --31-- trained cutting tools --32-- are fastened, which swore in the projection at a production of the rotor and attach directly together. The heads --35-- these cutting tools --32-- in addition, it could be so implemented that they overlap in such a projection each other slightly. A device, with more softly the rotor also from a majority of circular disks exists, which exhibit teeth on their extent similarly as with a gear wheel, belonged already to the state of the art. These Schneidezähne of the before-well-known device cut a comb profile from the Materialbahn, by separating granulates particles in each case along three lips. This before-well-known device possesses however the disadvantage of an inclination to resonance features, which have as a consequence that the free end of the Materialbahn on the rain-gauge flutters. The disks become during the device according to invention on the wave --30-- by means of on the threaded parts of the wave of screwed on nuts --33-- held together. Each longing oath tool --32-- consists of a shank --34--, which in an assigned recess of the disk --31-- fastened is, and by heart --35--, which two cuts --A and B-- exhibits, which in the sketch (Fig.5) include a right angle, in the intersection --C-- cross each other and from this intersection --C-- both diagonally upward run. These cutting tools --32-- are at the rotor for the center of the lateral surface of the rotor --15-- along a pair of gegerdäufiger spirals arranged, whereby each individual cutting tool in each case the cut running in longitudinal direction --A-- and the cut running transverse to the Zuführriehtung --B-- exhibits. The intersection --C-- the cuts --A and B-- points in direction of rotation of the rotor --15-- seen opposite the Zu£ührtisch --11-- in each case up, u.zw the free end of the longitudinal cut has the shortest distance --A-- in direction of rotation of the rotor --15-- opposite the Zuführtisch --11-- in the intersection --C-- the shortest distance. From the Fig.3 to 5 it is evident that with the impact of such a cutting tool --32-- on the Materialbahn --12-- a cut along two edges running in a right angle takes place to each other. If the two other edges of the Granulatteilehens are already free, e.g. if in accordance with Fig.6 the particle --1-- , receives one is cut off individual granulates particle in a Schnittvorgang. The represented and described arrangement of the disks --31-- and the cutting tools --32-- serves only as a remark example the device, which makes a simple attitude possible of the cutting tools in purchase to each other. To steep ones of disks --31-- can however for the attachment of the cutting tools naturally also different tool tools be used. With the Aus£ährungsbeispiel are the cutting tools --32-- in the way in two Sehranbenlinien, moving in opposite directions represented in Fig.2, arranged, those of ever an end of the disks --31-- formed rotor --15-- go out and in the longitudinal center of the rotor meet each other. Dern respective extent of the rotor the Schneldwerkzeuge becomes accordingly --32-- along one, two or several pairs of such spirals to be arranged can do. In accordance with Fig.2 only one pair of such Schrauberdinien runs over the entire length of the rotor, as may be understood must however a very long rotor into several longitudinal sections be divided, from which then everyone exhibits at least a pair of such spirals. The attitude of the longing oath tools --32-- taken place thereby that the Sehelben --31-- before clamping on the wave --30-- by means of the nuts --33-- in purchase to be rotated to each other. The impact of the device evident on the basis the Fig.6 is as follows: Becomes the rotor --15-- in turn and a plastic sheet shifts --12-- to the extent of the rotor --15-- advanced, then granulates particles become in the way represented in Fig.6 in exaggerated size from this course --12-- herausgesehnltten, u.zw become first two particles --1-- cut off, which are directly at the longitudinal folds of the course and are been because of the transverse edge, then become to these adjacent particles --2-- cut off etc. up to the particle --8--, on which then by the circulation of the rotor a new of Schneldwerkzeugen --32-- formed pair of spirals for effect gdangt, with the granulates particle --1 ', 2 ' etc. to 8 '-- are cut off. Thereby that cutting the particles off --1 to 8-- against the center of the course effected, it is guaranteed that itself the course --12-- shifts not sideways. Of course the invention is not to the represented and described characteristics of the example-wise Ausführungs£orm bound, but in the context of the actual EriVmdungsgedankens manifold modifyable,
