It is sliced by the circular knife, which are then picked up by the chain frame and placed on the table by a beater.
  • the slice thickness of the discs can be preset by moving the stop plate along the x-direction. Also, usually the stop plate is moved in the x direction in a marginal maximum displacement position, for example, to clean the circular knife easier and / or to be able to grind.
  • Operating modes can be provided in particular a normal operating mode for cutting normal slices as well as a maintenance mode in which particularly thick slices can be cut and / or the circular blade can be cleaned and / or ground.
  • a maintenance mode it is provided that the chain frame is dismounted on the machine housing while it is mounted in the normal operating mode.
  • this object is achieved in an equally surprisingly simple and effective manner in that the disk cutting machine has a sensor device for detecting the current mounting state of the chain frame.
  • a selection and / or a setting of an operating mode can then take place.

  • a warning signal for mounting the chain frame may appear. especially until the chain frame is actually mounted.
  • the sensor device comprises a current measuring device, preferably for measuring the chain frame motor current.
  • the status signal can be generated by measuring the chain frame motor current.
  • the chain frame motor current exceeds a predefinable minimum current value when the chain frame is mounted and its motor is in operation, for example because increased power is required to move the chains of the chain frame.
  • the condition signal can be derived by putting the chain frame motor into operation and measuring its power demand.
  • the minimum current value can be predefinable self-learning, in particular by a self-learning device.

From practice, it is known that just in slicing machines, z. B. for cutting meat, sausage or cheese, both special hygiene requirements exist as always with dirt, cut-offs or the like is to be expected. A non-contact determination can be carried out largely error-free even under such conditions and hygiene requirements are easy to fulfill.

  • the sensor device may be integrated in the attachment point.
  • a part of the contact switch may be integrated in the attachment point. If the chain frame is then fastened to the machine housing by means of the attachment point, the contact switch can be actuated automatically and thus determine that the chain frame is mounted. Accordingly, the contact switch can automatically detect that the chain frame is released when it is not fastened by means of the attachment point.
  • the attachment point may be embodied, for example, as a pin, which in a complementarily formed an electrical contact triggering recess in the Mounting the chain frame engages.
  • the attachment point is designed as an eyelet, wherein advantageously in such an embodiment, the contact switch, for example by pin-shaped configuration, engages during assembly of the chain frame in the eyelet and thereby an electrical contact is made.
  • the chain frame can be detached from the machine housing, for example, by moving it up to a removal position, alternatively or additionally by means of the roller switch, it is possible to detect a passing position, which can be an indicator for reaching the removal position, and the mounting state of the chain frame can be determined therefrom.

  • a maintenance mode can be enabled or disabled.
  • the maintenance mode can in particular allow the cut thicker slices. Under thick discs discs of more than 10mm, in particular more than 12mm, thickness can be understood.
  • the causes of one of the possible disruptions of the operating sequence described at the outset can already be avoided.
  • the operation mode for cutting thicker disks may be disabled as long as the status signal indicates that the chain frame is mounted. Then, thus, from the outset a space conflict between the stop plate and chain frame can be prevented.
  • the user can also be made aware of the mounting state if, when the operating mode is locked, a blocking signal or, when the operating mode is enabled, a release signal is output to the operator, preferably visualized on a display unit.
  • the blocking signal can also be designed, for example, in the form of a warning signal for disassembling the chain frame.
  • the release signal may be a warning signal, from which it appears that the current operating mode is enabled or usable.

Since a low load of the chain frame motor is to be assumed when the limit value is undershot, an undershooting of the limit value may be a characteristic of a demounted chain frame.
  • a particularly advantageous variant of the method results if, in the presence of a status signal from the sensor device, which indicates that the chain frame is currently mounted, a displacement of the stop plate over a predetermined maximum displacement distance is automatically locked, and that the stop plate only on this Limit can be postponed when the chain frame is removed from the machine housing.
  • a mechanical lock can shorten or lengthen the free displacement path depending on the state signal.
  • the sensor device supplies a continuously variable and / or multivalent state signal, in particular with more than two state steps. Then, for example, not only can it be detected whether the chain frame is mounted or not. It can then be detected, for example, in particular in the case of a chain frame that can be displaced in the x direction, whether or how far the chain frame is displaced along the x direction. Thus, for example, a release of a mode of operation also take place, although the chain frame is still mounted, but as far along the x-direction is shifted, that for the displacement of the stop plate enough free space is available.
