The lower knife 11 differs from the lower knives known in the prior art by a circumferential groove 11N , which act as a driver for a driver 13U serves (see 4 ) as described below.

3 shows a plate knife pair 3 consisting of a top knife 7 and a bottom knife 11 , in different views, with the upper knife 7 and the bottom knife 11 are in a cutting engagement, such as in the cutting device 1 is made when the upper knife 7 on the harmonic 5 and the bottom knife 11 on the lower shaft 9 located to one through the cutting device 1 to cut continuous web material into strips.

4 shows that on the harmonic 5 arranged upper knife 7 in cutting engagement with that on the lower shaft 9 arranged lower blade 11 , The waves 5 . 9 is each a linear table 25O . 25U assigned to the parallel to the associated shaft 5 . 9 runs.

On every linear table 25O . 25U is each a taker 13O . 13U arranged longitudinally displaceable, wherein the positioning of the driver 13O . 13U along the respective linear table 25O . 25U takes place by means of a control, not shown.

5 shows the linear table 25U with the driver arranged thereon 13U in a perspective view, but with the linear table 25O and the driver 13O each identical.

The driver 13U has a driver plate 13M on, along a peripheral portion of an engagement lip 13E which is essentially semicircular.

The driver plate 13M is by means of two Linerhubzylinder 27 in the vertical direction (in 5 from top to bottom) movable to the engagement lip 13E relative to the linear table 25U raise and lower.

The Linearhubzylinder 27 of the driver 13U are preferably each a pneumatic cylinder, and the activation of Linearhubzylinder 27 is specified by the controller, not shown.

As described below, the lower blade can 11 along the lower shaft 9 suitable to be positioned by the engagement lip 13E of the driver 13U is engaged with the groove 11N in the lower knife 11 , by suitable displacement of the driver 13U along the linear table 25U and raising and lowering the engagement lip 13E by means of Linearhubzylinder 27 ,

4 shows a storage area 17 the cutting device 1 in which on the waves 5 . 9 arranged and not needed for a current cutting knife 7 . 11 can be arranged. The knife 7 . 11 be in the storage area 17 arranged side by side, so that they rest against each other and a first in the storage area 17 pushed knife at a stop 15 the waves 5 . 9 is applied.

With reference to 6 Below is the method according to the invention for positioning the knife 7 . 11 on the waves 5 . 9 described.

First, a predetermined number of knives 7 . 11 by hand arbitrarily on the associated shaft 5 . 9 arranged, preferably only a short distance on the waves 5 . 9 pushed.

Subsequently, the controller moves the drivers 13O . 13U to a storage area 17 opposite end of the waves 5 . 9 and activates the Linearhubzylinder 27 such that the engagement lip 13E closer to the associated wave 5 . 9 hazards becomes, as for an engagement with a groove 7N . 11N necessary is.

The control activates the linear stages 25O . 25U following such that the drivers 13O . 13U towards the storage area 17 be moved.

During this shifting process, each driver plate beats 13M someday to a side surface 7S of the upper knife 7 or a side surface 11S of the lower knife 11 on, and in a further displacement of the driver 13O . 13U towards the storage area 17 be all knives 7 . 11 in the storage area 17 postponed.

In an alternative embodiment, the last on the shaft 5 . 9 pushed knives 7 . 11 at a mark 19 aligned, so that the control of the position of the groove 7N respectively. 11N is known, whereby the engagement lip 13E of each driver 13O . 13U can be moved by the controller so that it engages with the respective groove 7N . 11N to the then deferred knife through the then formed mold flow 7 . 11 in the direction of the storage area 17 to move. The mark 19 can have a bar mark on the shaft 5 . 9 be (perpendicular to the longitudinal axis) or may be formed by a laser pointer, which is at the center of the shaft 5 . 9 is directed to the groove 7N . 11N to align with a laser spot.

While moving the knives 7 . 11 towards the storage area 17 increases a displacement force, which is the linear table 25O . 25U must apply to the knives 7 . 11 in the storage area 17 to move, as more and more knives 7 . 11 through the carriers 13O . 13U while moving towards the storage area 17 move. To the driver 13O . 13U is for example a pressure sensor 21 arranged, which is in connection with the displacement control to the displacement force of the driver 13O . 13U to determine while the takers 13O . 13U towards the storage area 17 to be moved. Preferably, a servo drive is used, which is to operate switchable between a speed control and a torque control.

Be the drivers 13O . 13U continue towards the storage area 17 shifted, so are all the knives 7 . 11 to each other, with the last deferred knife on the driver 13O . 13U is applied.

In a further displacement finally proposes a rear side in the direction of displacement 7S . 11S the first pushed knife 7 . 11 at the stop 15 the respective wave 5 . 9 which, by means of the pressure sensor 21 measured displacement force steadily increases, although the drivers 13O . 13U Do not continue towards the storage area 17 move. The controller detects this situation (or exceeding a predetermined pressure force threshold) and stops moving the drivers 13O . 13U , Alternatively, in a speed-controlled servo drive, the drive current is monitored for the exceeding of a maximum value or determined at a torque control of the standstill by monitoring the position reporting signals.

The knife 7 . 11 are now juxtaposed and abutting each other, with a side face of a first on the waves 5 . 9 pushed knife at the respective stop 15 the waves 5 . 9 is applied. This standstill position is detected and stored by the control device.

The control calculates on the basis of the now reached position of the drivers 13O . 13U a total knife width MGL of the juxtaposed knives 7 . 11 , that is, the controller determines a distance of the driver 13O . 13U to the respective attack 15 the associated shaft, 5 . 9 ,

Because of the control the width of the knives 7 . 11 is known, the controller based on the total knife width MGL, the number of knives 7 . 11 on the associated shaft 5 . 9 to calculate.

With the help of the total width MGL and the number of knives, the controller can also control the position of the grooves 7N . 11N the knife 7 . 11 on the wave 5 . 9 to calculate.

Now to a required number of knives for a cutting operation 7 . 11 on the associated shaft 5 . 9 to arrange, for example, six lower blades 11 , becomes the engaging lip 13E of the driver 13U such in the storage area 17 move that with the groove 11N of the sixth lower knife 11 engages.

The controller then reverses the direction of travel of the driver 13U and there will be six bottom knives 11 from the storage area 17 ejected.

The with the engagement lip 13E of the driver 13U engaging lower blades 11 will be as long along the lower shaft 9 moved until it reaches the desired position on the lower shaft 9 has taken.

Then the engagement lip 13E from the sixth lower blade 11 solved, moved in the direction of displacement and brought into engagement with the fifth lower blade 11 ,

Now, five lower knives through the linear table 25U moved further until the fifth lower blade 11 is arranged at the desired position.

Again, the engagement between the engagement lip 13E and the groove 11N of the fifth lower knife 11 solved when the fifth lower knife 11 is suitably positioned, and the engagement lip 13E is engaged with the groove 11N of the fourth lower blade 11 , as in 6 shown.

This process is repeated until all lower knives 11 are positioned. The upper knife 7 are positioned in the same way.

Alternatively, the knives 7 . 11 individually from the storage area 17 pushed and positioned appropriately.

In the present embodiment, each wave is 5 . 9 a linear table 25O . 25U with a driver 13O . 13U assigned. Alternatively, the cutting device 1 only a linear stage with a driver on the between the harmonic 5 and the lower shaft 9 is movable to the knife 7 . 11 to position. Such a linear table can for example be moved along a U-shaped path, wherein in each case a shaft on the free legs of the U-shape 5 . 9 is arranged.

At the ends of at least one shaft 5 . 9 is advantageous in each case at least one Radialhubzylinder arranged to a mutual distance of the waves 5 . 9 to enlarge, causing the waves 5 . 9 on the one hand can be arranged in a cutting position relative to each other, in which the upper blade 7 in cutting engagement with the lower blades 11 stand, and the waves 5 . 9 on the other hand can be arranged in a displacement position in which the upper blade 7 not in cutting engagement with the lower blades 11 stand independently of each other along the respective shaft 5 . 9 through the carriers 13O . 13U can be moved. The Radialhubzylinder the at least one shaft 5 . 9 solve the knife 7 . 11 thus prior to positioning them from their cutting engagement by making the waves 5 . 9 move into the traversing position for positioning the knives. After positioning the knives, the radial stroke cylinders move the shafts 5 . 9 back into the cutting position, so that the upper knife 7 in cutting engagement with the lower knife 11 stand to cut web material into strips.

The Radialhubzylindern is preferably assigned in each case a Axialhubzylinder to before performing the radial offset axial misalignment of the waves 5 . 9 in the longitudinal direction of the waves 5 . 9 adjust. In this case, an axial offset and, with the aid of the radial stroke cylinders, a radial offset of the shafts is first adjusted by means of the axial stroke cylinders to form the shafts 5 . 9 to move from the cutting position to the travel position.

On the waves 5 . 9 arranged knives 7 . 11 completely replace, the controller moves the drivers 13O . 13U to the respective stop 15 and returns the direction of displacement of the respective driver 13O . 13U around, so all the knives 7 . 11 to the end of the wave 5 . 9 be pushed, that the storage area 17 opposite. Since the controller the number of knives 7 . 11 on the respective wave 5 . 9 is known, is moving the driver 13O . 13U stopped early, so that the last deferred knife 7 . 11 in a defined small distance from the free end of the respective shaft 5 . 9 which is the storage area 17 opposite.

Shall the knives 7 . 11 be arranged differently at the end of a cutting process for a subsequent cutting operation, that is, the number and / or the position of the knife 7 . 11 be changed, so the steps described above for positioning the knife 7 . 11 repeated, that is pushing all the knives 7 . 11 in the storage area 17 and the next repositioning of the required knives 7 . 11 ,

The knife 7 . 11 be in a known manner on the respective shaft 5 . 9 attached, for example by a positive connection or a frictional connection. A positive connection can be achieved, for example, in that one along the longitudinal axis of the shaft 5 . 9 in a groove extending wedge is pressed by compressed air into a notch in the knives 7 . 11 is formed. Is in the knives 7 . 11 no corresponding notch formed, so there is a frictional connection between the wedge and the knives 7 . 11 , In particular, in the latter variant, a plurality of longitudinally extending wedges may be provided, which preferably have a uniform angular offset with each other, to the best possible adhesion between the waves 5 . 9 and the knives 7 . 11 to achieve.

To move the knife 7 . 11 on the waves 5 . 9 To simplify, the waves can 5 . 9 during the positioning of the knives 7 . 11 rotate.

In this type of positioning of the knife 7 . 11 is crucial that these in the storage area 17 lie directly against each other and are not separated by, for example, house dust or cutting dust, otherwise the determination of the total width of the knife MGL would be subject to an error and the calculation of the number of knives 7 . 11 and in particular the calculation the location of the grooves 7N . 11N could not be done with the required accuracy. The waves 5 . 9 is therefore advantageous a cleaning device for the knife 7 . 11 assigned to the side surfaces 7S . 11S to get rid of dust and the like. The cleaning device may be formed for example by compressed air nozzles, along the longitudinal direction of the waves 5 . 9 are arranged at regular intervals to dust and the like from the side surfaces 7S . 11S the knife 7 . 11 to blow, preferably before carrying out the radial displacement of the waves 5 . 9 , The cleaning device may alternatively or additionally the drivers 13O and 13U be assigned along the engagement lip 13E For example, compressed air nozzles for cleaning the knife 7 . 11 exhibit. In this case, the knives 7 . 11 be cleaned by the driver 13O . 13U along the entire length of the waves 5 . 9 proceed to the knife 7 . 11 to clean. The cleaning device can also be in the form of brushes or a rubber lip on the drivers 13O . 13U be formed, which the side surfaces 7S . 11S the knife 7 . 11 mechanically clean when the drivers 13O . 13U in engagement with the respective knives 7 . 11 come.

Alternatively or in addition to a cleaning device, the knives 7 . 11 one spacer each 7A . 11A exhibit a mutual distance between the knives 7 . 11 adjust.

7 shows in different views a top knife 7 , which is the upper knife of the 1 to the fact that this additionally a spacer 7A having in the form of a circumferential spacer ring. Cutting dust accumulating when cutting the continuous web material is deposited on the spacer 7A off and can not be axial over the spacer 7A stand out, since he otherwise of the upper knife 7 would fall off. In this way it is ensured that the mutual distance between upper blades 7 solely through the spacer 7A is predetermined.

8th shows a variant of the upper knife 7 of the 7 in which the spacer 7A on an opposite side surface 7S is arranged. The spacer 7A and a cutting blade 7K of the upper knife 7 are thus on opposite side surfaces 7S of the upper knife 7 arranged.

9 shows different views of a lower blade 11 that the lower knife of the 2 except that it is a spacer 11A having. The spacer 11A is in turn formed as a circumferential spacer ring.

The spacers 7A . 11A of the 7 to 9 are each shown as a circumferential spacer ring. Alternatively, the spacers 7A . 11A be formed by each arranged by angular offset spacer lugs, for example by four spacer lugs, which in an angular offset of 90 ° to each other on a side surface 7S . 11S are arranged.

For example, become spacers 7A used in the upper blades, so do not necessarily have spacers as well 11A be used on the lower blades and vice versa.

The described knives 7 . 11 can both with one side surface 7S . 115 as well as with the opposite side surface 7S . 11S first on a wave 5 . 9 be pushed, that is, they are used on both sides. Because the grooves 7N . 11N the knife 7 . 11 however, are arranged asymmetrically, the control must be prior to positioning the knife 7 . 11 the control device are entered, in which orientation they have been postponed, so that they the position of the grooves 7N . 11N calculated correctly.
