Definitions
- the invention relates to a device for blowing out a rotating abrasive belt of a belt grinding machine, in particular a wide-belt sanding machine, with a definable relative movement between the abrasive belt and a nozzle assembly.
- a blower for blowing out an abrasive belt in which the air for blowing out of a nozzle arrangement with a plurality of arranged in a line transversely to the direction of rotation of the abrasive belt nozzles exits.
- the nozzle assembly is deflected laterally oscillating, whereby all areas of the abrasive belt can be cleaned evenly.
- this cleaning effect can only be guaranteed if the grinding belt has a fixed predetermined rotational speed. In the event that the speed of rotation of the abrasive belt is changed, however, not all areas of the abrasive belt are cleaned reliably.
- the effective and reliable cleaning effect is achieved, since in particular in a change of Circulating speed of the grinding belt, the oscillation frequency and / or the amplitude of a relative movement between the grinding belt and the nozzle assembly is changed.
- an oscillating movement of the nozzle assembly is generated by a drive unit.
- the nozzle arrangement is preferably driven by the drive unit in such a way that when the rotational speed of the grinding belt is increased, the oscillation frequency and / or the amplitude of the relative movement is increased.
- the oscillation frequency of the relative movement is changed such that the ratio of the rotational speed to the oscillation frequency of the relative movement remains the same, the amplitude of the relative movement being constant. It can thus be achieved that the distance between two deflection points of the preset Ausblasmusters remains the same in the circumferential direction in the change in the rotational speed.
- a fluid directed through a nozzle opening impinges in each case on a blow-out region on the grinding belt, if a blow-out pattern is produced on the grinding belt by the blow-off regions during the revolving movement of the grinding belt and an oscillating movement of the nozzle arrangement and if the extent of the blow-out regions increases or equal to the ratio of the rotational speed to the oscillation frequency of the relative movement.
- the amplitude of the relative movement preferably corresponds to the difference between the distance and the extent the blow-out areas. This ensures that the preset Ausblasmuster completely covers the researcherbasenden area of the abrasive belt.
- the amplitude of the relative movement is changed during the change of the rotational speed such that the ratio of the rotational speed to the amplitude of the relative movement remains the same, the frequency of the relative movement being constant. It can thereby be achieved that a characteristic angle of the preset Ausblasmusters remains the same in the change of the rotational speed.
- the nozzle openings are arranged at an equal distance from each other.
- partial patterns of the Ausblasmusters can be generated on the sanding belt, which have an equal distance transversely to the direction of rotation.
- a fluid directed through a nozzle opening impinges in each case on a blow-out region on the grinding belt, when the grinding belt is guided over a deflection roller and abuts the deflection roller in a deflection region and if the blow-off regions are generated only in the deflection region on the grinding belt , In the deflection region, the abrasive belt can be blown out better, since the abrasive grains of the abrasive belt in the deflection region have a relatively large distance from each other.
- the abrasive belt is guided over three pulleys.
- the three deflection rollers form a first triangular configuration, which is arranged behind the nozzle arrangement in the workpiece transport direction.
- the nozzle arrangement is arranged in particular on the chip side of the triangle configuration.
- the grinding belt is preferably driven in the opposite direction to the workpiece transport direction.

- the sanding belts in the two triangle configurations run in opposite directions.
- the workpiece is then machined first by means of the second triangular configuration abrasive belt and then by the first triangular configuration abrasive belt.
- the abrasive belt of the second triangular configuration is driven in synchronism with the workpiece transport direction. It is advantageous if the device has a first nozzle arrangement and a second nozzle arrangement and if the second nozzle arrangement is moved together with the first nozzle arrangement.
- two different nozzle arrangements for the blowing out of two sanding belts arranged opposite one another on different sides of the respective nozzle arrangement can be moved simply and reliably with a single drive unit.
- the device has sensors for detecting the contour of the workpiece to be machined
- the sensors are arranged in the workpiece transport direction in front of the nozzle assembly when the nozzle sections are individually activated via associated check valves, each nozzle section is assigned at least one sensor, and if the device has a control device which controls the blocking valves of the nozzle sections in accordance with the contour of the workpiece to be machined detected by the sensors.
- the device has a control device which controls the blocking valves of the nozzle sections in accordance with the contour of the workpiece to be machined detected by the sensors.
- the drive unit comprises an electromotive, an electromagnetic or a pneumatic oscillation drive.
- the nozzle arrangement comprises compressed air feeds to the nozzle sections, wherein each nozzle section is assigned a compressed air supply, and if the device has a control device which controls the compressed air supply to the nozzle sections such that with an increase of the rotational speed of the grinding belt increases the amount of compressed air becomes.
