  • the knife magazine allows a safe storage of one or more hand knife to be ground, which are then fed by a handling device the grinding process.
  • the cutting contour can be detected, so that when grinding this contour can be followed by the electronic evaluation and control unit.
  • an existing contour of a worn knife can thus be precisely reground.
  • stationary machining tools are provided. These editing tools, which can be motor driven then define a position at which the knife to be ground, for example, positioned with the aid of the handling device with its blade at the processing site and optionally guided during processing.
  • machining tools are preferably provided which rotate about a horizontally mounted axle, so that the hand knives to be ground can be guided along the tool in a substantially horizontal alignment.
  • two grinding tools of the same type are provided in a particularly advantageous manner rotating relative to one another, so that a knife edge can be machined from two sides at the same time.
  • different processing tools are provided, for example for grinding, for polishing and for deburring the knife blades.
  • a modular structure of the tools is provided, so that such a device can be constructed as needed with different tools.
  • the processing tools are arranged on a rear wall of a working space, since they also limit the working space on this side, the work tools are thus arranged at maximum safety distance to a standing at the front operating personnel.
  • the drive of the working tools can be done on the back of this rear wall, so that a separation of working and drive space takes place.
  • the drive side of the device is thus shielded from impurities that may occur in the working space by the grinding process itself or by appropriate abrasives, for example in the form of abrasive emulsions or the like.
  • the rear wall is assembled by individual modular plates, so that the replacement or installation of a tool can be done by appropriate replacement or construction of such a plate.
  • the individual module plates together form the rear wall of the working space and separate it from the drive space.
  • the sensor unit is accommodated for detecting data of the contour of the knife edges in the drive space, so that the sensor unit is also wheatfully protected against contamination.
  • an opening in the rear wall for example in one or more of the described modular wall panels of the rear wall, can be provided, through which the knife blade can be inserted.
  • adjacent plates can also be realized by recesses on a respective plate a corresponding opening in the rear wall of the working space.
  • a magazine is provided for a plurality of knives, in particular a larger plurality of knives, so that the Degree of automation is increased.
  • a magazine can be formed in a particular embodiment in the form of a box having a cover plate.
  • knife receptacles can be arranged, in which the hand knife with its blades can be inserted.
  • Such a magazine has the advantage that the blade side of the knife protrude into the interior of the box and thus are shielded by the wall, while the knife handles on the cover side is accessible.
  • This type of knife magazine offers a high level of occupational safety. In principle, however, other magazine designs are also possible with great certainty, in which the blade side of the blades is shielded from the outside and the blade handles are accessible from the outside.
  • an insertion contour is provided in a knife holder, which facilitates the insertion or insertion of the knife blades with the aid of the handling device.
  • a knife holder which facilitates the insertion or insertion of the knife blades with the aid of the handling device.
  • Such an introduction may for example be funnel-shaped or formed with a ramp.
  • a mechanical insertion aid By means of such a mechanical insertion aid, a greater tolerance can be provided in the accuracy of the handling device in the area of the knife magazine.
  • the positioning of the knife magazine can be made with greater tolerance, as well as a not exactly striking the blade receiving knife can still be inserted reliably by the insertion when inserting by the handling device.
  • the blade receptacles and / or the insertion aids are at least partially elastic.
  • the blade holder can yield when inserting a slightly offset impacting knife, so that the knife blade can still be inserted into the receptacle.
  • a firm fixation of the knife in the magazine is ensured by reshaping the elastic regions of the knife holder or the insertion aid.
  • the grinding process is preferably carried out so that a hand knife on the handle is gripped by the gripper, so that no embracing for the initiation of the grinding process is required, as would be the case if the knife in the Blade area would be detected by the gripper.
  • the knife is fed with the aid of the handling device of the one or more sensor units, so that the data for detecting the grinding contour can be read or tapped.
  • the handling device can then feed the corresponding hand knife to the different processing tools.
  • the knife is first fed to a grinding tool, where the knife profile is exactly on or reground.
  • an angle in the cutting edge can then be ground exactly following the previously ground profile, this angle either being determined beforehand by the sensor unit or adjustable depending on the intended use, preferably being selectable from a multiplicity of stored setting options.
  • the evaluation and control unit can then guide the knife for deburring to the corresponding deburring tool. In a corresponding manner, a polishing process is carried out afterwards, if a polishing tool is provided.
  • such a machine can also be used to grind a pre-programmed profile in a knife, for example, in the new production of the knife.
  • the particular advantage including the sensor unit results in regrinding, as this can be followed precisely a predetermined profile.
  • the machine 1 comprises a machine frame 2, which carries the other components.
  • a handling device in the form of a cross slide 3 with vertical boom 4 and gripper 5 facilitates movability of the gripper 5 in three coordinate directions.
