Definitions

  • the present invention is based on a device for cutting food products with a cutting element arranged in a cutting plane, a cutting bar, via which the food products can be fed to the cutting plane, and a sensor.
  • slicers typically elongate or rod-shaped food products, such as sausage or cheese, are cut into slices with a high cutting capacity, for example with up to 1,000 cuts per minute or more.
  • the food products are single-track, i.e. individually or in multiple lanes, i.e. parallel to each other, by means of a feed unit to the cutting plane in the area of the cutting element.
  • the food products are sliced by the cutting element, in particular a rotating circular or sickle blade.
  • the thickness of the slices results from the feed of the individual food products between two cuts.
  • the cut slices are usually arranged and packed into portions with a constant number of slices and/or with an exact weight.
  • the cutting bar of such slicers generally has a number of recesses or openings, through which the food products are conveyed by means of suitable feed devices and finally fed to the cutting plane. Because the perimeter of such openings also acts as a counter edge for cutting, the shape and dimensions of the openings are closely related to the shape and dimensions of the food products.
  • the cutting bar can be deformed and/or displaced for a variety of reasons. For example, it is possible that, due to production-related deviations in the dimensions and/or shape of the bar-shaped food, the food products may collide with the cutting bar, as a result of which the cutting bar may be at least partially displaced and/or deformed in the direction of the rotating cutting element.
  • the document EP 3 900 899 A1 discloses a slicer which comprises a contactless scanning device for detecting at least part of the outer contour of the products to be sliced.
  • the dimensions of the products could in turn be determined from the determined outer contour by simple calculations in order to deduce whether the food products fit through the openings of the cutting bar, in order to ultimately avoid a collision between the cutting bar and the food.
  • DE 102020 106 054 A1 discloses a sensor that determines the height of food products measured at right angles to the support surface, the infeed belt. Initial information could also be derived from the height as to whether it would be possible for the food products to pass through the openings.
  • neither of the two publications discloses how, in the event of a collision between the cutting bar and the food due to excessively large product dimensions, a possible collision between the cutting bar and the cutting element can be prevented in order ultimately to prevent production downtime.
  • an at least partial displacement of the cutting bar in the direction of the cutting plane can be detected by means of the sensor.
  • the sensor is used for direct or indirect position detection of the cutting bar.
  • a stop signal for example, can be generated in good time, which stops the rotational movement of the cutting blade and thus prevents the cutting blade from colliding with the cutting strip. It is conceivable that when a limit value is exceeded with regard to the change in position of the cutting strip, such measures are initiated that prevent a collision between the cutting strip and the cutting element. As a result, damage to the machine and, in particular, production interruptions to replace damaged machine components or longer production downtimes can be avoided. Overall, the service life of the device according to the invention can be increased and time and costs can thus be saved.
  • the cutting bar is at least partially plate-shaped and has at least one recess, the food products being able to be fed to the cutting plane through the recesses.
  • the cutting bar can be designed to be essentially flat and arranged largely perpendicularly to the feed belt of the cutting device.
  • the cutting bar can be arranged in the end area of the feed belt with respect to the conveying direction, in order to realize the transition and the transfer of the foodstuffs into the cutting plane.
  • Several, in particular circular and rectangular, openings can be formed in the cutting strip. The elongate food can be gradually pushed through such openings by the feed device, while the cutting element cuts the food into slices directly behind the cutting bar.
  • the openings or a lower section of their inner edges can serve as an abutment for the cutting element.
  • an element is formed on the cutting strip, the element being configured in particular as a projection or pin, and the sensor being able to interact with the element.
  • an element specially designed or mounted, in particular screwed or driven in, for determining the position can be provided on it.
  • a bolt or pin or a cuboid element can be driven into a hole or recess formed on the cutting strip.
  • a cut from the surface of the cutting strip be formed excellent projection, so that the projection and the cutting bar are monolithic as it were.
  • the displacement or deformation of the cutting strip leads directly to a change in the position of the element, and the change in position of the element can be detected by the sensor.
  • a change in position can advantageously be detected when the element completely leaves the detector field of the sensor.
  • exceeding a predefined displacement or deformation limit value of the cutter bar can be detected by the entry of the element into the sensor field.
  • the element is preferably arranged centrally with respect to a linear dimension of the cutting bar.
  • the element can be arranged particularly advantageously on an axis of symmetry of the cutting bar. At such a position of the element, displacements of the cutting bar, in particular for applications in slicers, can be detected particularly well.
  • the greatest linear dimension of the cutting bar can extend transversely to the conveying direction and parallel to the infeed belt.
  • the element can be arranged particularly well in the middle on an upper edge of the cutting strip with the greatest linear dimension of the cutting strip. Furthermore, the element can be detected particularly well by the sensor at this upper edge due to its good optical accessibility.
  • the senor is configured optoelectronically.
  • the precise distance to the element can be recorded with an optoelectronic sensor. If there is a relative change in the distance between the sensor and the element, i.e. an absolute change in the position of the element, the cutting device can be switched off and a collision between the cutting strip and the cutting element can be prevented.
  • an optoelectronic sensor can detect the presence of the element upon entering its detector array by the element causing a break in a light beam. The sensor can then cause an actuator to switch off the slicer.
  • a further object of the invention is a method for operating a device according to one of the preceding configurations, the position of at least a partial area of the cutting strip relative to the cutting plane being monitored by means of the sensor.
  • Food whose dimensions are too large for the openings of the cutting bar can collide with the cutting bar and be pressed against it.
  • the cutting bar can be displaced at least partially in the direction of the cutting plane and thus of the cutting element while the food is being fed forward.
  • the position of the cutting bar can be monitored. The monitoring can take place by observing a particularly suitable partial area of the cutting strip using the sensor, with the suitability being able to be characterized by a position that is particularly susceptible to displacement.
  • Positions that are particularly prone to displacement can be those that are relatively distant from the storage locations of the cutter bar, since they have the greatest possible leverage and allow greater deflections. In this way, the distance between the cutting strip and the cutting plane can advantageously be controlled and the device can be switched off if the cutting strip approaches the cutting plane too closely. The sensor can therefore avoid any production downtimes.
  • a particularly preferred embodiment of the invention provides that the cutting element is configured as a sickle or circular knife, with a rotation of the cutting element being stopped upon detection of a defined change in position of the at least one partial area of the cutting strip.
  • Sickle and circular knives can be made of stainless steel to meet hygiene requirements in the food industry. Because of their shape, which approximates a planar disk shape, sickle or circular knives can define a cutting plane particularly well, to which the distance

  • a partial area of the edges of the openings 13 serve as a counter edge 10 during the cutting process.
  • the cutting plane 5 - thus also the sickle knife 7 arranged therein - and the surface of the cutting bar 9 facing away from the conveyor belt 4 are spaced apart, the distance between the sickle knife 7 and the cutting bar 9 defining the thickness of the sausage slices.
  • the rotational speed cp of the sickle blade 7 and the feed speed of the sausage loaf 3 are matched to one another in such a way that the desired slice thickness is achieved.
  • the cutting bar 9 can be pushed in the direction by the pressure of the sausage loaf 3 deform the cutting plane, with the risk that the cutting bar 9 collides with the sickle blade 7.
  • an optoelectronic sensor 11 is arranged on the device 1 .
  • This sensor 11 is designed here as a reflection light barrier, i.e. a transmitter and a receiver are arranged in the same sensor housing.
  • the transmitter emits a light beam along the cutting bar 9. If the light beam in the detector field of the sensor 11 hits an obstacle or the pin 15 acting as a reflector, the light beam is remitted, i.e. diffusely scattered, with at least part of the remitted light beam radiating back to the receiver.
  • the light beam reflected back to the receiver then generates a signal, in particular a stop signal for actuating a brake, which stops the rotating cutting element 7 and thus prevents a collision between the cutting element 7 and the cutting bar 9 .
  • the sensor 11 can be designed as a one-way light barrier.
  • the transmitter and the receiver are arranged in separate housings and directly opposite one another along the cutting bar. In this way a direct light beam can be sent from the transmitter to the receiver, where an interruption of the light beam can generate a stop signal for braking the cutting element 7 .
  • the light beam can be directed through a hole arranged in the pin 15 become. If the deformation of the cutting bar and, as a result, the displacement of the pin 15 exceeds a limit value, the light beam is interrupted by the material border of the bore arranged in the pin 15 and the sensor 11 generates the stop signal for braking the cutting element 7. It is also conceivable that the light beam is guided past the pin 15 and the pin 15 only enters the light beam and interrupts it when a displacement limit value is exceeded, and the stop signal is thus generated.

  • a first step 101 of the method the position of the pin 15, which is arranged on the cutter bar 9, is monitored. Since the position of the plate-shaped base body of the cutter bar 9 is not monitored, one can speak of indirect monitoring. For this purpose, a light beam is continuously emitted by the transmitter of the optoelectronic sensor 11 and it is constantly checked whether the light beam arrives at the receiver.
  • This first step 101 corresponds to the undisturbed control operation of the device 1.
  • a second step 102 of the method 100 is initiated, in which the sensor 11 generates a stop signal.
  • the second step 102 is initiated when, for example, end pieces of food sticks that have not been properly ejected block the conveying path of the belt conveyor in front of the cutting bar and cause a deformation and/or displacement of the cutting bar 9 .
  • a third step 103 of the method 100 the stop signal generated in the second step 102 is sent to the brake of the cutting element 7, whereby the brake is actuated and the cutting element 7 is stopped in order to avoid any damage resulting from a collision of the cutting bar 9 with the cutting element 7 .
  • the cause of the change in position of the cutting bar 9 can be remedied and the cutting element 7 or the device 1 can be put back into operation.
