Definitions

  • the invention relates to a method according to the preamble of the first independent Claim.
  • the process is used for cutting continuously and flat objects conveyed parallel to their main surfaces along predetermined cutting lines that are parallel to the conveying direction run.
  • the method is particularly suitable for cutting of flat objects that are difficult to cut because, for example, are easily deformable and / or several if necessary there are also easily deformable layers, which layers only stick little together. Multi-page printed products made of relatively thin Papers are such items.
  • the invention further relates to a device according to the preamble of corresponding claim for performing the method.
  • Cross-cutting devices transverse to their major surfaces continuously funded, flat objects are, for example, from the Publication EP-367715 (F271) discloses devices for cutting objects continuously conveyed parallel to their main surfaces, for example from publication US-3069952 or from publication EP-0698451. In the case of funding, they lie parallel to the main areas of the cutting objects the specified cutting lines transverse to the conveying direction, is the arrangement of the two cutting edges across the conveying direction align. Since a finite period of time is necessary for the cutting process it is also obvious for such a cut that for a high cutting accuracy the cutting device at least during the Cutting process with the object to be cut got to.
  • the object of the invention is to demonstrate a method with the continuously, with a constant conveying speed and essentially Flat objects conveyed parallel to their main surfaces along predetermined cutting lines aligned parallel to the conveying direction are to be cut between two cutting edges, one first of the cutting edges in the support or conveying plane of one to be cut
  • the object lies and the second cutting edge for the cutting process is moved past the first cutting edge and advantageously crosses with this.
  • the cutting method according to the invention by appropriate guidance at least the second cutting edge Sufficient to very high cutting qualities even with low contact pressures can be reached.
  • it should be possible to be difficult too cutting objects e.g.
  • the invention is based on the knowledge that printed products that are made from consist of several pages, then with a slight pressure or even without to be pressed against a support surface with sufficient to very good cut quality can be cut if at any moment of Cutting process at least that point of the second cutting edge, involved in the cutting process (crossing point with the first Cutting edge or cutting point), a relative speed the object to be cut, which is as perpendicular as possible to the Support level or to the first cutting edge or to the main surfaces of the cutting object is directed. That means it is enough if only this cutting point on the second cutting edge is an absolute speed has, the component in the conveying direction as exactly as possible is as big as the conveying speed.
  • At least the second, cutting edge moved against the support plane so matched to the continuous conveyance of the objects to be cut moves that too at least the cutting point of each cutting process
  • Cutting edge has a speed whose component in the conveying direction is the same as the constant conveying speed.
  • the holding devices have the function, the products to hold such that they are at the first cutting edge and advantageously rest on a bearing surface containing the first cutting edge.
  • Such a movement of the second cutting edge is easiest can be realized by crossing them with the first cutting edge a constant swivel speed around one above the support level arranged, stationary pivot axis moved past the first cutting edge is, the pivot axis is perpendicular to that plane in the two cutting edges are arranged.
  • the cutting speed that is, the speed, with which the cutting point on the main surface of the moving object depends on the swiveling speed and the position of the pivoted, second cutting edge relative to Pivot axis. This location can be freely selected within wide limits.
  • the device according to the invention for carrying out those described above essentially consists of a pair of blades aligned in the conveying direction, each with a essential straight cutting edge.
  • the first cutting edge is in the Support plane of the object to be cut arranged
  • the second Cutting edge is about a swivel axis above the support level pivotable.
  • the second cutting edge lies in a plane that is aligned perpendicular to the pivot axis.
  • the first cutting edge arranged to be cut is sufficient, if it is stationary. But this cutting edge can also be moved such that the relative speed in the conveying direction between the first Cutting edge and object to be cut is minimized.
  • FIG. 1 shows a simple diagram which can be used to explain a preferred embodiment of the method according to the invention.
  • the figure shows a line with arrow F as the conveying direction of the objects to be cut, one of which is shown and labeled G.
  • Line F simultaneously represents a section through the support or conveying plane for objects G to be cut and a first cutting edge SK 1 aligned in this supporting plane and parallel to the conveying direction.
  • the figure also shows a second cutting edge SK 2 , which is about a stationary pivot axis M is pivotable relative to the first cutting edge SK 1 in a plane perpendicular to the pivot axis M and at a constant pivoting speed ⁇ .
  • the second cutting edge SK 2 is crossed with the first cutting edge, that is to say in cutting engagement.
  • the point S 1 of the cutting edge SK 2 is first in cutting engagement with the first cutting edge SK 1 , that is, S 1 is the cutting point.
  • the cutting point moves to the left on both cutting edges.
  • the cutting engagement ends at position SK 2 'of the second cutting edge when point S 2 (position S 2 ') forms the cutting point of the second cutting edge.
  • the speed component v F in the conveying direction is therefore independent of the radius with which the cutting point moves around the swivel axis, i.e. it is constant at constant ⁇ during the entire cutting process and always the same as the tangential speed of a point that is at a radius with the angular speed ⁇ y rotates around M.
  • the cutting edge SK 2 must be returned from its swivel position after cutting (SK 2 ') to the starting position (SK 2 ). This can be achieved either by swiveling in the opposite direction to swiveling for the cutting process or by rotating about the swiveling axis M in the same direction as the swiveling for the cutting process. Since the above explanations show that the swiveling speed ⁇ must be constant for the cutting process, the rotation variant is more advantageous, since a constant angular speed can be realized more easily for a rotation than for a cyclical swiveling back and forth.
  • a cutting process according to FIG. 1 begins at the leading edge of the object G in the conveying direction and ends at its trailing edge.
  • an object G can be completely cut in a single cutting process if its extent in the conveying direction is not greater than the distance between the points S 1 and S 2 'plus the distance which it is moved forward during the cutting process.
  • the second cutting edge is advantageously designed in such a way that its start and end areas are not used for cutting an object, that is to say that the path S 1 -S 2 'is advantageously designed such that it is larger than the extent in the conveying direction of the object to be cut.
  • FIG. 1 It can also be seen from FIG. 1 that the cutting angle (angle between the two cutting edges involved in the cutting process) decreases during the cutting process, the cutting speed decreasing with increasing initial cutting angle ⁇ . It can be seen from the above derivation that the cutting angle ⁇ has no influence on the speed component v F , that is to say that it can be freely selected, as required by the task.
  • FIGS. 2 to 5 This is further illustrated by FIGS. 2 to 5, in which arrangements are shown which correspond to the arrangement according to FIG. 1 except for the initial cutting angle ( ⁇ .1 to ⁇ .4).
  • the pivot position of the second cutting edge SK 2 at the beginning of the cutting process and SK 2 'at the end of the cutting process is again shown in each of FIGS. 2 to 5.
  • FIG. 2 shows a larger initial cutting angle ⁇ .1 than the initial cutting angle ⁇ of FIG. 1. Since the initial cutting angle ⁇ .1 opens away from the pivot axis as in FIG. 1, the object G is cut from the leading edge as in FIG , Since the angle ⁇ .1 is larger than ⁇ (FIG. 1), the cutting speed is lower.
  • Figure 3 shows an initial cutting angle ⁇ .2, which opens against the pivot axis M, whereby the cutting process begins at the trailing edge of the object G to be cut.
  • the speed ratios are the same as in FIGS. 1 and 2.
  • Figure 4 shows a special case, a second cutting edge SK 2 , which is arranged radially relative to the pivot axis M.
  • the initial cutting angle ⁇ .3 is also open in such a case against the pivot axis M (cutting process begins at the trailing edge of the object G) and is equal to the angle whose sine y / r is 2 .
  • the time span that is necessary for such a cut is theoretically zero and practically only dependent on the thickness (extension in the direction y) of the object G.
  • the condition of Limitation of the relative speed to a component perpendicular to the main surfaces of an object G to be cut can be fulfilled.
  • FIG. 6 shows an exemplary embodiment of the device according to the invention with a carrier 10, on which a plurality of blades 11 with second cutting edges SK 2 are arranged in a star shape and which is one by a distance y above the support plane of the objects G to be cut or above the first Cutting edge SK 1 arranged pivot axis M and is driven to rotate at a constant angular velocity ⁇ .
  • the blades 11 are to be arranged such that the distance S 1 -S 2 'is at least as large as l minus the distance by which an object is transported forward during a cutting process (at least as large as l for short cutting times). If n (for example three) second cutting edges are provided, the corresponding blades are each offset by 360 ° / n (for example 120 °) in order to arrange the center of the carrier 10.
  • FIG. 7 shows very schematically an exemplary embodiment of the device according to the invention with a rotating carrier 10 on which six blades 11 with second cutting edges SK 2 are arranged in a star shape such that the objects G fed in the conveying direction F are cut from their trailing edge, as is the case here has already been described in connection with FIGS. 3 and 4.
  • FIGS. 6 and 7 show star-shaped carriers with three or six blades 11 with second cutting edges SK 2 .
  • the number of blades 11 is to be matched to the blade arrangement (cutting angle) and to an easily realizable range of the rotational speed. As already mentioned in connection with FIG. 1, it is also possible to arrange only one blade with a second cutting edge on a corresponding rotating support.
  • FIG. 8 shows two embodiments of devices according to the invention, which are designed in this way.
  • FIG. 8 shows a conveying direction for objects G to be cut, again represented by an arrow F.
  • the cutting area is shown schematically by the pivot axis M and by a pivotable, second cutting edge SK 2 .

Between the conveyor belts represented by arrow F. brake cams 15 are moved. These brake cams 15 are, for example on an endless chain 17 running over two deflection wheels 16 arranged and moved such that they are in the cutting area over the The support level of the objects protrude and is slightly slower in the conveying direction move as the pair of conveyor belts. Through these brake cams are the objects fed on the conveyor belts before they are in the Reach the cutting area, lightly braked and precise for the cutting process clocked. During the cutting process, they guide those to be cut Items.
  • a plurality of blades 18 with first cutting edges SK 1 can now also be arranged on the same chain 17.
  • These blades are, for example, pivotably arranged on the chain and spaced from the brake cams in such a way that they can be positioned in the cutting area outside the conveyor belts.
  • the blades 18 With a moving link 19, the blades 18 are guided at least in the cutting area such that the first cutting edges SK 1 are positioned in the support plane of the objects to be cut.
  • first cutting edges SK 1 have the same speed in the conveying direction as the brake cams, that is to say also the same speed as the objects to be cut.
  • an entire cutting device in the sense of a pair of scissors, which has a first and a second Has cutting edge on two blades pivotable relative to one another about a swivel axis, with which the objects to be cut are carried along. So that the condition of the relative speed of the second cutting edge, which is to be limited to a component perpendicular to the support plane, is fulfilled in such a case, the pivot axis must be arranged in the support plane.
  • FIG. 9 shows a bird's eye view of an arrangement with three devices 30.1 to 30.3 according to the invention for three-sided trimming of printed products P with, for example, bound, stapled or glued back R.
