Definitions

  • the invention relates to a method for operating a slicing machine for cutting slices of slices from strand-shaped slicing material, preferably food, with a cutting device which comprises a circular knife rotating in a cutting plane around an axis of rotation, driven by an electric circular knife motor, with a support plate for placing the slicing material carrying carriage, which can be moved at a carriage speed v S parallel to the cutting plane, and with a chain of a chain frame operated by means of an electric chain frame motor for transporting cut slices of material to be cut at a transport speed v T and for placing them on a support table or a conveyor belt, whereby before the start of the cutting operation a number n ⁇ 2 of strands of material to be cut are placed parallel to each other on the support plate with their strand axes aligned in the direction of the cutting plane, so that during a carriage stroke one Number of n slices of material to be cut is cut from the n strands of material to be cut.
  • the material to be cut in electrically operated slicing machines for string-shaped food such as sausages, ham, salmon, cheese, etc.
  • the cutting device usually in an x-direction perpendicular to the cutting plane, in which a rotating circular knife revolves.
  • the conveyed material to be cut is cut into slices by the circular knife.
  • the slices of material to be cut are placed one after the other on the support table or on the conveyor belt by means of the chain frame, in particular an offshoot of the chain frame.
  • the slices of slices are to be processed further, for example when wrapping asparagus stalks with ham slices or when filling rolled-up sausage slices with cream cheese, the slices of slices must always be slightly spaced from one another.
  • the slices of material to be cut are deposited in single-type, spaced-apart rows of slices.
  • a further disadvantage of the known solutions is that the spacer devices often have to be set to the desired pane spacing in a very complex manner and / or only have a very narrow adjustment range for the pane spacing.
  • the object of the present invention is to provide a generic method of the type defined at the outset and a corresponding slicing machine in a cost-effective manner and with readily available technical means. This is intended to make it possible, in particular in a reproducible, operationally reliable and particularly simple manner to deposit slices of material to be sliced that are spaced apart from one another with a defined slice spacing.
  • the slide and the chain frame should be able to be controlled automatically by the disk cutting machine.
  • ⁇ t ⁇ v T can correspond to the desired lateral distance between two adjacent cut slices of slices on the chain of the chain frame.
  • the invention is based on the knowledge, which in retrospect appears quite plausible but has never been used consistently, that the chain frame is cut off by varying the current slide speed v S (t) and / or by varying the current transport speed v T (t) Slices can be placed at different positions on the chain or subsequently on the storage table or the conveyor belt. Thus, by varying these parameters, the distance between the panes can each be set to a desired level.
  • the slide due to its mass and the chain of the chain frame due to the construction of the drive have a certain inertia.
  • the carriage speed and the transport speed of the chain frame are functions of time, since the carriage and chain are each accelerated and braked.
  • the carriage speed v S (t) and the transport speed v T (t) of the chain frame are synchronized.
  • the present invention eliminates precisely this synchronization of the carriage speed v s (t) and the transport speed v T (t) of the chain frame, which is desired and considered necessary in the prior art.
  • the desired result - slices spaced apart from one another with a predeterminable slice distance - can be achieved particularly easily and inexpensively by particularly skillful control of the slicing machine.
  • the instantaneous transport speed v T (t) can be varied, in particular adjusted, by accelerating or decelerating the chain frame motor.
  • the slicing machine can also have a separate carriage motor for driving the carriage.
  • the instantaneous slide speed v S (t) can then be varied, in particular adjusted, by accelerating or braking the slide motor.
  • At least one thickness of a strand of material to be cut can also be taken into account when selecting the speed levels ⁇ v S , ⁇ v T and / or the duration ⁇ t.
  • the method according to the invention can be used regardless of the shape of the strands of material to be cut.
  • the method can also be used successfully with non-cylindrical strands of material to be cut.
  • stacks of slices spaced apart from one another or, preferably on the conveyor belt, rows of disks spaced apart from one another, each with the desired Number of cut slices of slices per row of slices can be generated.
  • step (d) can then be automatically initiated for the respective strand of material to be cut.
  • the power consumption of the (electrical) circular knife motor depends on the current length of the current cutting line on the circular knife.
  • the cutting line can in turn be used as an indicator for the current cutting position within a strand of material to be cut. For example, it can be expected that in the case of a cylindrical strand of material to be cut, the power consumption initially increases up to the middle of the strand (cutting line becomes longer) and then falls again to a minimum (cutting line that becomes shorter). This minimum, a power consumption typical for a cutting process and / or reaching a predefined limit current value can thus be detected and used as an indicator to determine whether or when a strand of material to be cut is completely cut through and thus a slice is completely cut off.
  • a slice spacing that is constant for all rows of slices can be achieved if the duration ⁇ t is selected to be less than the time required to completely cut off a slice of slice from the strand of sliced material with the smallest cross section.
  • Intuitive and fast input of the data required for control is made possible by entering the number n and the width of the strands of material to be cut by manually approaching the respective strand position relative to the cutting edge of the circular knife at the respective starting positions of the n strands of material to be cut for the cutting process to be carried out and by transmitting the each position reached is effected to the control device.
  • the beginning of the first strand of material to be cut can be picked up by manually moving to the first starting position.
  • the starting position of the second strand of cut material By approaching the starting position of the second strand of cut material, the starting position of the second strand of cut material and the end position of the first strand of material to be cut.
  • the initial position of the third strand of cut material and the end position of the second strand of cut material can be recorded. It can be taken into account here that the third strand of material to be cut can rest against a wall of the carriage and thus the end position of the third strand of material to be cut can be known from the outset. It therefore does not need to be specifically approached.
  • the scope of the invention also includes a slicing machine for carrying out the method according to the invention with a cutting device which comprises a circular knife rotating in a cutting plane around an axis of rotation, with a carriage carrying a support plate for placing the material to be cut, which runs at a carriage speed v S parallel to the cutting plane E can be moved, and with a chain frame operated by means of a chain frame motor for the removal of cut slices of material to be cut at a transport speed v T and for storage on a storage table or a conveyor belt, a control device being present which sets the beginning and the end of each time interval of the time period ⁇ t, the current slide speed v S and the current transport speed v T of the chain frame controls.
  • the method according to the invention can be carried out without problems on such a slicing machine. It thus enables cut slices of slices to be deposited at a predeterminable, desired lateral distance.
  • control device can be designed as a computing unit or have a computing unit on which a computer program product is stored in an executable manner.
  • the slicing machine has a sensor device for detecting the current slide position relative to the axis of rotation of the rotating circular knife and / or for detecting the current cutting state of the strand of material that was last in contact with the circular knife.
  • the sensor device can be connected to the control device in terms of data.
  • the current slide position can thus be determined.
  • the point in time at which an end of a strand of material to be cut has been reached can be determined via the cutting state.
