Definitions
- the invention relates to a method for the continuous grinding (sanding) of web-shaped, textile fabrics and device for carrying out the method.
- the multi-roller sanding machine for sanding the surfaces and the single-roller machine for sanding the surface.
- the goods are drawn in tensioned condition over four to seven rolls covered with emery paper turn against or in the direction of the goods.
- the goods are brought into frictional contact with the emery surface with more or less adjustable pressure.
- the protruding fibers are split up by the emery and result in a velvety but very low fiber pile.
- the effect may be finer or coarser.
- Many articles are first sanded on relatively coarse and then on fine sanding rollers.
- twine knots can dodge and are not sanded and opened if they are set accordingly.
- the emery rollers hardly heat up. This gives the sandpaper a longer service life.
- the mechanical energy is divided by the number of emery points and is therefore lower.
- the individual rollers are disengaged or set to "freewheel". With the thumb you then set the respective emery roller in rotation and at the same time increase the wrapping of the goods (product coating angle). This is continued until the roller can only be turned with strong pressure. This process must be repeated for each batch, since the emery effect changes due to the wear of the emery device and, moreover, there are differences even with two identical product qualities, e.g. B. as a result of stretching and moisture. This procedure is expensive and uneconomical because of the long downtimes.
- the effect assessment is based on empirical values, which, however, are weakened in their meaningfulness if the disturbance variables already mentioned negatively influence the result of the sanding process.
- the grip of the emery paper, its signs of wear, the reaction of the goods to the set tension, the risk of wrinkles, particularly in the longitudinal direction, the stretching behavior of the goods even at different moisture levels and possible electrostatic charges can adversely affect the result.
- the object of the invention is to provide a method and a device for carrying out the same, with which the frictional relationships between the surface structure to be ground and the grinding tool are always kept constant, regardless of the type, the elongation behavior, the tension of the surface structure and the condition of the grinding tool.
- the fabric is in contact with one and the same grinding tool at several points.
- the actuator and the grinding drum are connected to a controller which is set to the desired value predetermined by the type of fabric and, in the event of a difference between the desired value and the actual value of the grinding drum, the actuator in the sense of an enlargement or Decreased the angle of attack actuated.
- the friction torque on the respective grinding drum required for the optimal grinding effect is determined by specifying a current value (setpoint). Motorized readjustment of the painting angle is carried out via this setpoint until the setpoint specification corresponds to the current of the grinding drum motor (actual value). This also takes into account the degree of wear on the emery grain. In the case of more worn abrasive coating, a larger friction surface is required to achieve the same friction torque than with new grain. If the maximum permissible coating angle is exceeded, an acoustic or optical signal can be emitted at the same time, which indicates the degree of wear and indicates the need to renew the sanding cover of the grinding drum. With the detection of the frictional torque from the current consumption, the contact pressure force (normal force) resulting from the tangential material tension is also recorded and included in the measurement result, which can be clearly seen when looking at the purely physical processes.
- FIG. 1 indicates a grinding tool in the form of a grinding drum, on the peripheral surface of which an abrasive paper covering is applied.
- This grinding drum 1 can be set in rotation by an electric drive motor 2.
- the electric drive motor 2 is connected to a current source 5 via corresponding lines. However, it is also connected via lines to an electrical controller 6, which is connected via lines to a motor-driven actuator 7.
- This actuator 7 has a screw spindle 8, in which a rod 9 is freely rotatable, but is non-displaceable in the axial direction. The free end of this rod 9 carries the paint roller 4th
- the controller 6 is set to the empirically determined target value predetermined by the type of fabric 3. If, during operation, this setpoint is undershot, for example, due to the fact that, as a result of the wear of the grinding layer on the grinding drum 1, the frictional force between the sheet 3 and the grinding drum 1 becomes smaller, then the controller 6 effects the difference between the setpoint and the actual value of the lower frictional torque acting on the grinding drum 1, actuation of the actuator 7 in such a way that the painting roller 4 in FIG. 2 of the drawing is moved downward via the screw spindle 8. The consequence of this is that the angle of attack ⁇ and thus also the contact area a is increased.
- controllers 6 of this type are commercially available per se, further details can be dispensed with.
- the fabric 3 is in contact with one and the same grinding drum 1 at several points, namely at two points a.
- FIG. 4 of the drawing discloses a two-drum grinding device with two contact points a per grinding drum 1.
- FIG. 5 of the drawing A comparable embodiment is also shown in FIG. 5 of the drawing, while FIG. 6 reveals a total of three contact points a per grinding drum.
