Definitions

  • the invention relates to a cutting device for a rod machine in the tobacco processing industry, comprising a knife carrier with at least one knife holder, in which a knife is arranged, the knife carrier having a drive shaft mounted in a housing and a drive for rotating the knife carrier about a rotation axis A is assigned, the knife being adjustable in the radial direction relative to the knife holder, an adjusting device for adjusting the knife carrier to different formats, such that the angle ⁇ formed between the axis of rotation A of the drive shaft of the knife carrier and the or each strand to be cut can be changed, and a grinding device for grinding the or each knife during operation of the cutting device, the grinding device having a grinding wheel holder with at least one grinding wheel which can be driven in rotation about a rotation axis B by means of a drive, and the grinding wheel holder being connected to the housing of the drive shaft and arranged in this way in the area of the knife carrier is that the or each knife comes into contact with the or each grinding wheel due to the rotation of the knife carrier.
  • the invention further relates to a method for adjusting the position of the or each grinding wheel of a grinding device in a cutting device for a strand machine in the tobacco processing industry according to one of claims 1 to 8, comprising the steps: determining a target position of the or each grinding wheel in relation to the or each knife for each cutting format, setting the target position for the respective cutting format to be cut, so that the or each knife comes into contact with the or each grinding wheel driven about the rotation axis B with each revolution about the rotation axis A.
  • Such cutting devices and methods are used in the tobacco processing industry in order to produce individual rod-shaped articles, namely tobacco sticks, filter rods, etc., from strands, for example tobacco, tobacco mixtures, filter material and other materials or material combinations common in the tobacco processing industry cut.
  • the rod-shaped articles are separated by a knife arranged on a knife carrier, which describes a running circle due to the rotation of the knife carrier, when the knife hits the strand to be cut essentially perpendicularly.
  • the knife is arranged in a knife holder which can be adjusted automatically in the radial direction and which in turn is rotatably arranged on or in the knife carrier.
  • the knife carrier itself is arranged with its drive shaft inclined to a strand (in a single-strand machine) or to the strands (in a multi-strand machine).
  • the axis of rotation A of the drive shaft is at an angle ⁇ to the or each strand.
  • Different formats are usually processed on a strand machine. This means that strands or rod-shaped articles, for example with different diameters and/or different lengths, the so-called formats, are processed.
  • the adaptation to the different geometric relationships of the strands/items is therefore also called a format change.
  • the strand usually runs through the strand machine at a constant speed. During cutting, the speeds of the strand on the one hand and the speed of the knife on the other must correspond. In other words, when cutting, the knife must move with the strand at approximately the same speed in order to produce an optimal cut. At the time of cutting, when the knife is perpendicular to the strand, the speed of the knife corresponds approximately to the strand speed.
  • the ⁇ angle which lies between the axis of rotation of the drive shaft of the knife carrier and the strand, is changed in such a way that the knife speed for the changed format again approximately corresponds to the strand speed.
  • the cutting device is usually assigned a grinding device.
  • a grinding device has a grinding wheel holder with at least one grinding wheel.
  • the grinding wheel holder is assigned to the knife carrier in such a way that grinding wheels arranged on cantilever arms of the grinding wheel holder protrude into the running circle of the knives. Due to the shape of the grinding wheel holder with the grinding wheels arranged on the cantilever arms, it is also referred to as a grinding antler.
  • the grinding wheel holder itself is connected to the knife holder, for example via the housing, so that an adjustment of the knife holder, i.e. a change in the angle ⁇ , inevitably leads to a corresponding adjustment of the grinding wheel holder.
  • the grinding wheel holder is basically stationary in relation to the knife carrier during operation, so it does not rotate with the knife carrier.
  • the kinematics of the knife carrier mean that when the ⁇ angle is adjusted, the grinding antler must also be adjusted in order to produce an approximately identical knife geometry when grinding.
  • the grinding pattern also changes.
  • the knife height or knife length is changed by the changed grinding pattern.
  • the grinding wheel holder In order to achieve the optimal grinding wheel position, for example for a consistent knife geometry, the grinding wheel holder must be adjusted relative to the knife carrier, namely around the rotation axis A of the drive shaft. In other words, there is an optimized grinding wheel position for every format or every format setting of the knife carrier.
  • the optimal grinding wheel position also influences the knife length and knife sharpness in particular. Due to the adjustment of the knife holder during a format change to a changed angle ⁇ and the resulting adjustment of the grinding wheel holder about the axis of rotation A and/or due to wear of the grinding wheels, the distance between the grinding wheels and the knives also changes. This means that if the format is changed and/or the knives are worn and the knives are subsequently readjusted radially, the distance between the grinding wheel and the knife must also be readjusted. The distance is changed by moving the grinding wheel in the direction of the rotation axis B of the grinding wheels.
  • a cutting device with the features of the preamble of claim 1 is described in the EP 0 163 813 A described.
  • the invention is therefore based on the object of creating a cutting device which is optimized with regard to the adjustment of the grinding wheel positioning. Furthermore, the task is to propose an improved method for adjusting the target position of the grinding wheels in relation to the knife.
  • the grinding device comprises means for longitudinally axially adjusting each grinding wheel relative to the grinding wheel holder towards and away from the knife. This ensures direct and quick adjustment of the grinding wheels.
  • the means advantageously comprises a servo drive.
  • a servo drive which usually includes a servo motor and a servo amplifier and possibly other control elements, ensures quick and precise adjustment of the grinding wheels.
  • a particularly preferred embodiment is characterized in that the cutting device is assigned a control and/or regulation system for controlling and/or regulating the position of the or each grinding wheel in relation to the or each knife.
  • the knives of the cutting device are assigned a sensor for detecting the knife length and/or the knife sharpness, with the or each sensor being connected to the control and/or regulation system.
  • the combination of servo drive for the grinding wheel on the one hand and sensor for detecting the knife length and/or knife sharpness on the other hand enables fully automatic grinding wheel adjustment and grinding wheel tracking in a particularly simple and effective manner.
  • the task is also achieved by a method with the steps mentioned at the beginning in that the setting of the target position is carried out automatically by automatically adjusting the or each grinding wheel in the longitudinal direction of the rotation axis B of the grinding wheel.
  • the grinding wheel for setting the target position stands still during the infeed onto the knife until the knife, rotating about the axis of rotation A, comes into contact with the grinding wheel and thereby takes it with it, the increments then increasing as the grinding wheel rotates Drive of the grinding wheel are counted and when a target value of the increments is reached corresponding to the target position of the grinding wheel, the axial adjustment of the grinding wheel is stopped and the drive for rotating the grinding wheel about the axis of rotation B is started.
  • the grinding wheel rotates for adjustment the target position during the axial adjustment towards the knife around the rotation axis B until the knife rotating around the rotation axis A comes into contact with the grinding wheel and thereby brakes the grinding wheel, the decreasing number of increments in the grinding wheel drive being counted during braking and When a target value of the increments corresponding to the target position of the grinding wheel is reached, the axial adjustment of the grinding wheel is stopped.

  • the grinding device 18 has a mechanism for automatic and controlled adjustment of the or each grinding wheel 20 in the longitudinal direction of the axis of rotation B of the grinding wheel 20.
  • the mechanism can be designed and set up for the synchronous adjustment of all grinding wheels or for the individual adjustment of each individual grinding wheel.
  • the adjustment can either be done indirectly, for example via the adjustment of the grinding wheel holder 19, or directly on the grinding wheels 20.
  • the grinding wheels 20 are preferably adjustable directly in the longitudinal direction of their axes of rotation B.
  • the grinding device 18 includes means for longitudinally axially adjusting each grinding wheel 20 relative to the grinding wheel holder 19 towards the knife 13 and away from the knife 13.

  • the cutting device 10 can be assigned a control and/or regulation system for specifically controlling and/or regulating the position of the or each grinding wheel 20 in relation to the or each knife 13.
  • the control and/or regulation system is connected to a database in which the grinding wheel position previously determined empirically, computationally, by measurement or otherwise is stored for each cutting format. Due to this assignment, the corresponding position of the grinding wheels 20 is inevitably known when the angle ⁇ is adjusted.
  • Each component for example the adjusting device for the knife holder 11 or the mechanism for adjusting the grinding wheels 20, can each have its own system.

There is also the possibility of monitoring the knives 13, particularly with regard to the knife length and/or the knife sharpness, using sensors and then adjusting or readjusting the grinding wheels 20 if there are deviations from predetermined parameters.
  • the grinding wheel 20 stands for setting the target position (corresponds to the ideal position for grinding the knives 13 to the ideal knife length and ideal knife sharpness), so it does not rotate while the grinding wheel 20 is automatically moved towards the knife 13.
  • the knives 13 rotate with the knife carrier 11 about the axis of rotation A.
  • the knife carrier 11 can be rotated back and forth during the adjustment, i.e. it rotates with a changing direction of rotation. In other words, the knife carrier 11 is pivoted back and forth. As soon as the grinding wheels 20, which are automatically moved in the axial direction, come into contact with the knives 13, the knives 13 take the grinding wheels 20 with them.
  • the rotation of the knives 13 about the axis of rotation A causes them to rotate about their own axis of rotation B through contact with the grinding wheels 20.

As soon as the knives 13 rotating about the axis of rotation A come into contact with the grinding wheels 20, which are also rotating, this causes the knives 13 to brake the grinding wheels 20. Again, the increments in the drive of the grinding wheels 20 are counted. By braking the grinding wheels 20, the number of counted increments is reduced compared to an unbraked grinding wheel 20. The number of increments corresponds to a specific angle value by which the grinding wheels 20 are rotated.
  • a reduction in the number of increments, for example by 10% means, for example, that a previously determined, measured or otherwise determined ideal value/target value of the increments corresponding to the target position of the grinding wheels 20 in relation to the knife 13 has been reached.
  • ideal values/target values exist for every cutting format. As soon as the respective ideal value/setpoint is reached, the axial adjustment of the grinding wheels 20 is automatically stopped.
  • the grinding wheel holder 19 can also be adjusted relative to the knife carrier 11 so that the grinding pattern that matches the format can be generated on the knives 13. To do this, the grinding wheel holder 19 is released, moved into the desired position and then fixed again. The grinding wheel holder 19 can be loosened, adjusted and fixed manually or automatically.
  • the method is particularly preferably carried out with a cutting device 10, as described above.
