Definitions
- the invention relates to a circular knife scissors for separating thin single or multi-layer flat materials according to the preamble of claim 1.
- the specified circular knife scissors should make it possible to use thin single-layer, in particular also multi-layer, sheets of materials with low tear strength, e.g. Newsprint, or from materials with high elongation and low mechanical stresses, e.g. Aluminum and plastic foils, with the avoidance of waves and wrinkles in the entry area to produce strips with high accuracy and cut quality. Furthermore, a safe entry into the scissors is to be ensured and a dust accumulation or a development of dust during the longitudinal division of clippings, which are formed with several layers of thin fibrous or fibrous material, are reduced or avoided.
- the invention has for its object to provide a circular knife scissors of the type mentioned, in which a flat cut consisting of one or more layers, which is elastic or is compressible, has low tensile strength or high elongation with low mechanical stresses, is drawn into the scissors and divided into strips of constant width with good cutting edge quality, with essentially no cutting dust.
- two circular knife disks 4 with acute-angled cutting edges which have a cutting edge angle ⁇ , are attached to a drivable shaft.
- the cutting edge angle ⁇ is the angle that the Generating the side surface perpendicular to the shaft axis and the conical end face of the cutter disc is included.
- Two knife disks 4, which form a pair of knife disks, are arranged in such a way that the side surfaces each containing the cutting edges are furthest apart from one another, their distance corresponding to a strip width.
- spacer rings 8 or, in turn, for economical storage, a plurality of spacer rings with certain widths can be arranged side by side according to a type of modular system.
- a cutting spacer ring 6, 6b is used to set a further strip width, or several cutting spacing rings 6, 6a are also used for the above reasons.
- drive disks 7, 7a Concentrically on the cutting distance rings 6, 6a, 6b, drive disks 7, 7a, which are essentially the same width, are preferably arranged between the individual pairs of cutter disks or a cutter disk and a stop for limiting the width of the scissors.
- These drive plates 7, 7a are made of a resilient elastic material, e.g. Rubber or the like. Which largely prevents sliding on the surface thereof, in particular of the flat material 1, and have an outer diameter which approximately corresponds to that of the cutter disks 4 or is larger.
- a resilient elastic material e.g. Rubber or the like. Which largely prevents sliding on the surface thereof, in particular of the flat material 1, and have an outer diameter which approximately corresponds to that of the cutter disks 4 or is larger.
- counter-knife disks 5, 5a are arranged such that their right-angled cutting edges and the acute-angled cutting edges of the knife disks 4 of the shaft 2 touch or overlap one another and interact to produce a cut, and the end faces of the counter-knife disks 5,5a on the Drive plates 7, 7a rest against the surface.
- An attitude or alignment of the counter-knife disks 5, 5a, which may have different thicknesses, on the counter-knife shaft is accomplished by counter-knife spacer rings 9, 9a, their individual thickness and number in each case again being able to be carried out side by side according to a modular system.
- the clippings 1 When cutting into strip-shaped parts, the clippings 1 are pressed in a straight line against the counter-cutter discs 5, 5a by the elastic, non-sliding driver discs 7, 7a and are thus prevented from shifting laterally, the acute-angled cutting edges of the cutter discs 4 being at the right-angled edges of the respective counter-cutter discs 5 , 5a effect a sharp cut with high quality.
- the driving disks on the one hand bring about a secure, even pulling of the material into the scissors, on the other hand it is clamped down in a straight line or pressed against the end faces of the counter knife disks 5,5a in the cutting area, which causes wave formation of the clippings in the entry area and the occurrence of high tensile stresses in the layers are largely avoided.
- This embodiment has the advantage that no additional tensile stresses are formed in the clippings.
- fixed elements for securing the strip discharge can also be provided, which protrude from the discharge side in a tongue-like manner into the space between the knife disks 4, 4 'and / or into the space between the counter knife disks 5, 5'. It can also be advantageous to execute the counter-knife disks in two parts with the interposition of a spacer ring with a smaller diameter or in one piece with an end groove and to arrange a ring 13, 14 with material properties such as those of the driving disk in the created cavity. This has the advantage of further securing the retraction of a tabular clippings 1.
- Fig. 3 shows schematically in cross section devices 12 and 12, by means of which annular elements can advantageously be held and displaced in the discharge direction. As a result, an essentially rectilinear discharge of the strips can be achieved even if there are any clamps between the cutter disks.
- FIG. 4 shows a knife disc with a wavy cutting edge formation.
- cylindrical jacket partial surfaces 41 are alternately introduced at an angle in the conical end face of the cutter disk 4. This shape of the cutting edge enables an additional reduction in the cutting pressure.
- rollers in front of the cutting elements for optionally smoothing clippings, in particular consisting of several layers.
- the rollers can advantageously be made of an elastic material such as e.g. Rubber or foam can be formed and extend essentially over the entire width of the entry area of the circular knife shears, an embodiment with narrow rollers and counter-rollers distributed over the length of the shafts being economically advantageous.
- the inventive design of the circular knife scissors also significantly reduces the amount of cut dust.
- a further reduction in the development of dust while increasing the cutting edge retention of the knives and improving the operational safety of the scissors is achieved by hardening and / or coating the surfaces caused by knife and counter knife disks.
- the surface can be hardened, for example, by nitriding and is particularly wear-resistant; Coating the panes with, for example, MoS2 or, if appropriate, with hard materials such as TiN and the like, using a CVD or PVD process, in particular has an improving effect on the sliding properties of the surfaces and thus reduces cut dust.
