Definitions

  • the invention relates to a method and a device for processing screwed-in brushes, in particular for processing interdental brushes.
  • the device has a tool in the form of a rotationally symmetrical hollow body with an abrasive inner surface.
  • Screwed-in brushes are previously known in various embodiments from the prior art. They are used, among other things, as so-called interdental brushes and are used to clean interdental spaces. When using these brushes, bristle ends of bristle filaments of the brushes come into direct contact not only with the tooth flanks to be cleaned, but also with the comparatively sensitive gums of the user. Contact with the ends of the bristles can damage the sensitive gums.
  • the object of the invention is therefore to provide a method and a device of the type mentioned at the beginning which reduce or even avoid the risk of injuries when using such twisted brushes on the gums of a user.
  • the sharp edges or burrs described above can occur on the bristle ends when the individual bristle filaments are severed or shortened to the correct length during the manufacture of the brushes.
  • the brush can first be inserted into the grinding sleeve before the free bristle ends of the brush are ground off.
  • the introduction of the brush into the grinding sleeve can take place by an insertion movement of the brush relative to the grinding sleeve, by a pushing-on movement of the grinding sleeve relative to the brush or by a combined movement of the brush and grinding sleeve.
  • the brush can be arranged centered within the grinding sleeve in the processing position.
  • the grinding sleeve used to grind the free bristle ends of the brushes can have a rough surface on its inside, which faces the brush and its bristle facing when the grinding sleeve is used, or it can be coated with an abrasive.
  • the grinding sleeve is moved relative to the brush in order to generate a grinding movement. It is also possible to move the brush relative to the grinding sleeve in order to produce the aforementioned grinding movement for grinding the bristle ends. In a further embodiment of the method it can also be provided that the grinding sleeve is moved relative to the brush and the brush is moved relative to the grinding sleeve.
  • the brush and / or the grinding sleeve can be rotated about a longitudinal center axis of the brush and / or the grinding sleeve. In this way it is possible to grind the bristle ends of the bristle filaments of the twisted-in brush evenly, to remove burrs and / or sharp edges and to round the bristle ends in this way. It can be particularly useful if the brush and the grinding sleeve, if both are driven and moved in order to generate the grinding movement, are each rotated in the opposite direction of rotation.
  • the brush and / or the grinding sleeve can be moved linearly or axially in relation to a longitudinal center axis of the brush and / or grinding sleeve.
  • the linear or axial relative movement thus generated can be superimposed on a rotating relative movement of the brush and / or grinding sleeve. In this way, the free bristle ends of the screwed-in brushes can be processed particularly thoroughly, but nevertheless quickly.
  • the brush and / or the grinding sleeve can initially be rotated in a first direction of rotation and then in a second, opposite direction of rotation. This favors a uniform grinding treatment of the bristle ends of the screwed-in brushes.
  • a brush can be machined in succession by at least two grinding sleeves. It is possible here for the at least two grinding sleeves used for machining the brush to have different degrees of grinding. It is conceivable, for example, to use a first grinding sleeve with a coarser degree of grinding in order to first coarsely process the brush. Another grinding sleeve can then be used, which has a finer grinding degree and thus allows a finer grinding processing of the bristle ends of the screwed-in brush.
  • the object mentioned at the beginning is also achieved with a device for processing screwed-in brushes which has the means and features of the independent claim directed to such a device.
  • the device have at least one clamping device for a screwed-in brush and at least one grinding sleeve for grinding free bristle ends of a brush clamped in the clamping device.
  • a device for processing screwed-in brushes is created which has an end rounding of Allowed bristle ends of screwed-in brushes and which can also be set up to carry out the method described above and claimed in the corresponding claims.
  • the at least one grinding sleeve of the device can expediently be set up to accommodate at least one bristle facing of the brush to be processed. This can mean that a depth of the at least one grinding sleeve corresponds to at least one dimension of the bristle facing measured along a longitudinal center axis of the brush. In this way, the brush can be inserted completely into the grinding sleeve, at least with its bristle facing, in order to grind off the free bristle ends of the screwed-in brush.
  • a length of a grinding surface of the grinding sleeve that can be measured in the direction of insertion of the brush into the grinding sleeve is at least as great as a length of the bristle facing of the brush that can be measured in the same direction.
  • a grinding sleeve whose grinding surface has a length which can be measured in the direction in which the brush is inserted into the grinding sleeve and which is shorter than a length of the bristle facing which can be measured in the same direction.
  • the brush should be guided along the grinding surface at least once, but preferably several times, for thorough processing of its free bristle ends.
  • the device can be set up to move the clamping device and / or the grinding sleeve in order to generate a grinding movement for processing the free bristle ends of the brush.
  • a device is created which is used to generate a movement of the grinding sleeve relative is set up to the clamping device or vice versa. Both rotating and linear or axial relative movements come into consideration here as relative movements.
  • the clamping device and / or the grinding sleeve can be rotated around a longitudinal center axis of the brush and / or the clamping device and / or the grinding sleeve in order to generate a grinding movement. It is also possible to move the clamping device and / or the grinding sleeve linearly in relation to a longitudinal center axis of the brush and / or the clamping device and / or the grinding sleeve. It can be particularly advantageous if a linear movement can be superimposed on a rotating movement to generate a complex or combined grinding movement.
  • the grinding sleeve it is possible to drive the grinding sleeve to rotate about a longitudinal center axis of the grinding sleeve, while the clamping device with a brush clamped thereon is set in an axial movement relative to the rotating grinding sleeve.
  • This axial relative movement which can be carried out with the clamping device, can preferably be an alternating axial movement. In this way, particularly thorough grinding of the free bristle ends of the screwed-in brush can be achieved.
  • the grinding sleeve and the clamping device can be aligned relative to one another in such a way that their longitudinal center axes are congruent.
  • the device can have a rotary drive.
  • the grinding sleeve and / or the clamping device can be set in rotation by the rotary drive. It is also possible for the device to have a linear drive with which the clamping device and / or the grinding sleeve can be moved linearly or axially.
  • the device has a rotary drive for the at least one grinding sleeve. In this way, the at least one grinding sleeve can be set in rotation relative to the at least one clamping device and thus relative to an open brush.
  • the device can be equipped with a linear drive with which the at least one clamping device for the screwed-in brush can be moved linearly relative to the rotatable grinding sleeve. In this way, a device for machining screwed-in brushes is created, which is set up to generate a complex and / or combined grinding movement.
  • the device can have a suction device with at least one suction opening.
  • This at least one suction opening can be assigned to the at least one grinding sleeve. It can be particularly advantageous if several suction openings are provided or even at least one suction opening is assigned to each grinding sleeve of the device. In this way, the grinding dust that arises when grinding the screwed-in brushes can be reliably removed.
  • the device is designed as a carousel machine and has a plurality of clamping devices for screwed-in brushes, which run along a closed path.
  • the clamping devices can be arranged on a common retaining ring of the device. This retaining ring can be rotated about an axis of rotation of the device by means of a carousel drive. So the individual twisted brushes that can be clamped on the multiple clamping devices, are gradually fed to the individual stations of the device, for example individual or multiple grinding sleeves of the device.
  • the device has at least two or three or more grinding sleeves.
  • Each of the existing grinding sleeves can have its own degree of grinding, so that a sequential processing of brushes with grinding sleeves of different grinding degrees is possible.
  • a brush can, for example, first be processed with a grinding sleeve that has a comparatively coarse degree of grinding. The brush can then be fed to further grinding sleeves with an increasingly finer grinding degree. In this way, burrs or sharp edges on the free bristle ends can be gradually and reliably ground off and the bristle ends rounded.
  • the device has a cleaning device for processed brushes, it is possible to free the brushes of any sanding dust that may have adhered and to clean them for subsequent process steps.
  • the cleaning device of the device is a compressed air cleaning device. In combination with the suction device described above, it is then possible to blow off the processed brushes and to remove the grinding dust loosened by blowing off with the aid of the suction device from the device for processing screwed-in brushes.

  • the at least one grinding sleeve can consist of a grinding stone or also of sanding paper wound into a sleeve.
  • the at least one grinding sleeve can, however, also be produced in a generative manufacturing process, in particular sintered or 3D-printed.

This makes it possible to generate comparatively complex grinding sleeve geometries in a particularly simple manner. The same also applies to those grinding sleeves that are manufactured in a generative manufacturing process. Here too, complex grinding sleeve geometries can be generated comparatively easily.
  • the at least one grinding sleeve can have at least one cross-sectional constriction on its inner circumferential wall.
  • This cross-sectional constriction can be in the form of a hurdle and / or Inside the grinding sleeve, a grinding force on the free bristle ends of the screwed-in brush can be increased. This is particularly the case when the grinding sleeve and / or the brush are to be moved not only in a rotating manner but also with a linear movement relative to one another in order to generate a grinding movement.
  • the cross-sectional narrowing in the grinding sleeve can, for example, run helically around the longitudinal center axis of the grinding sleeve.

  • This inclined surface can connect the cross-sectional constriction to the inner peripheral wall of the grinding sleeve. Starting from the inner peripheral wall, the inclined surface can rise to the level of the cross-sectional constriction. This creates a smooth transition from the inner circumferential wall to the cross-sectional constriction within the grinding sleeve and promotes gentle, yet thorough grinding processing of the free bristle ends of the screwed-in brushes.
