- the line according to the invention works extremely stable and, for example, when slicing cheese, in particular hard cheese, for example a Dutchman or a leerdammer, the "giveaway" can be reduced to almost zero The individual portions no longer have to be supplemented so that their packaging is more hygienic and less complicated is.
- the present invention relates to a line for slicing food bars into a plurality of portions, which are subsequently packaged with a packaging machine.
- a food bar is preferably a sausage, cheese or ham bar. These food bars often have a substantially constant cross-section. In general, the food bars, such as a sausage, are elongated, i. their cross-section is much smaller than their length. In general, the food slices are perpendicular to
- the food bar can also be a natural ham or a food bar which is composed of several parts.
- a scanner is used to determine data about the inner and / or outer structure of the food bar, wherein the outer structure is, in particular, the circumference of the food bar and the inner structure is, in particular, its local density.
- Suitable scanners are optical scanners, for example, on laser and / or
- Photocell technology based and / or X-ray scanners which also detect the inner structure of the food bar.
- the scanner is an x-ray scanner.
- the scanner may be located upstream of the slicer or may be part of the slicer.
- the food bars are screened disc wise with a transmission scanner.
- This transmission scanner for example an X-ray scanner, has a radiation source and a sensor, for example a photosensitive sensor, which is located on opposite sides of the circumference of the food bar.
- This sensor is, for example, a line scan camera.
- the radiation source emits jets which enter on one side of the periphery of the food bar, penetrate the food bar over its entire width and are received on the opposite side from the sensor.
- This sensor measures the intensity of the received rays, which are attenuated as it passes through the food bar, the attenuation depending on the local nature of the food bar, for example its density.
- the radiation is carried out over the entire width of the product, wherein preferably only one, particularly preferably integrated over the width of the scanning wheel integrated value per scanning disk is determined.
- the naturalstrahlscanner is preferably provided stationary and the food bar is, preferably along its

Preferably, however, a curve is laid by the measured values and this curve is stored. Furthermore, it is also possible in each case to interpolate between two values. The computer unit therefore preferably knows which measured value at which position along the longitudinal axis of the Food bar was determined. In the event that not with a uniform
- Scan disc thickness is used, in addition, the respective thickness of the scanning must be registered and stored or taken into account in the determination of the curve.
- the sum P of all values determined by the sensor is formed.
- the thicknesses of the scanning discs are not uniform, it may be advantageous if a sum weighted with the slice thickness is formed. The sum is also saved.
- the food bar in the same orientation in which he was also transilluminated, handed over to a slicer, which divides it into portions.
- a certain length x N must be separated from the food bar, which corresponds to the desired target weight G of the respective portion, wherein a portion comprises at least one, preferably several food slices.
- the cuts of the slicing machine are substantially parallel to the
- Transmission direction of the transmission scanner and are preferably arranged substantially perpendicular to the longitudinal center axis of the food bar. If this is not the case, a mathematical correction of the respective data record must be made.
- the initial position of the food bar when cutting as exactly as possible corresponds to the initial position during scanning, so that the stored during scanning longitudinal coordinates match the longitudinal coordinates when slicing.
- the length (x N ) to be separated from the food bar is calculated.
- a factor k is first of all calculated by dividing the weight W of the food bar by the sum P of all measured signals of the scanning discs.
- the computer unit knows which length x N for the respective portion is to be separated from the food bar. This process is preferably repeated for each serving until the food bar is cut open.
- the target weight can also be from food bar to food bar be calculated differently in order to obtain the largest possible number of complete and well-weighted portions within the specifications and thereby avoid an incomplete last portion or residual slices.

According to the prior art, each track was then associated with a checkweigher which determined the weight of the respective portion in the respective track before it was packed. This balance now eliminates the invention.
- the packaging machine can be a form-fill-seal packaging machine, for example a so-called thermoformer, or a tray sealer or any other packaging machine known to those skilled in the art. According to the invention, neither the weight of the individual cut food slice nor the finished portion between the slicing machine and the packaging machine is determined. Surprisingly, this weighing step can be omitted at this point.
- a checkweigher is provided downstream of the packaging machine, which determines the weight of the respective packaging and preferably transmits the weight to a computer unit. These data can later serve as proof that the manufactured packaging complies with the prepackaging regulation.

- Food bars are sliced into food slices and thereby portions as accurate as possible in weight are generated.
- a food bar is first weighed with a balance and then with a feed belt through the fürstrahlscanner 6, preferably an X-ray scanner promoted. Weighing the food bar can also be done after scanning. However, the weight of the respective food bar can also already be known, so that weighing can be dispensed with.
- the scanner 6 the product is scanned slice by slice.
- the external structure in this case the circumference, and the internal structure, here the local density, are determined. After the food bar has been scanned, it is scanned by means of the

- the of the transmitted-through scanner data are either directly to the
- Slicing device is now controlled on the basis of the data obtained during scanning so that portions as weight-accurate as possible.
- the respective food portions which as a rule consist of several food slices, are transferred to a weighing device 8, in particular a dynamic balance, in order to check whether the desired setpoint weight has been maintained.
- the weighing device is multi-lane, wherein the number of tracks of the slicer corresponds to the number of tracks of the weighing device.
- the balance 8 is a dynamic balance, because the weight of the respective portion must be carried during its transport to the downstream packaging machine 10.
- a loading device is arranged, which inserts the respective portion into a packaging tray, which is transported along the packaging machine 10.
- the respective portion is packed in a package and then weighed again with the checkweigher 1 1.

- Through-scan scanner determined data are either transferred directly to the slicing or to another control unit / CPU, where they are further processed as needed.
- the slicing process in the slicing apparatus is now controlled on the basis of the data determined during scanning in such a way that portions which are as accurate as possible in terms of weight are produced.
- the respective food portions which generally consist of several food slices, are transferred to a loading device 3 which feeds the respective portion into a packaging tray along a
- the packaging machine 4 which determines the weight of the respective portion.
- the packaging machine 4 the respective portion is packed in a packaging and then weighed with the checkweigher 5 for the first time.
- the checkweigher 5 is recommended by the prepackaging regulation to ensure and document compliance.
- the signal from the checkweigher 5 is preferably used to control the slicing device, to calibrate the
- a weight factor for the next food bar to be sliced can be calculated with the checkweigh 5 signal. For this, all weights of all portions of a food bar can be added up and sent to one to the scanner and / or the slicer
- Cutting line is tracked so that the data determined by the balance can be clearly assigned to a food bar and / or a certain slicing track of the slicer and this can then be controlled, for example, targeted if the measured weight is not sufficiently close to the target weight.
- no scale is provided before or after the scanner to determine the weight of the food bar.
- the food bar is then transported through an X-ray scanner 1.
- the X-ray scanner makes a gap-taking of the food bar e.g. every 0.1 mm.
- the width of the gap is set, for example, by the speed with which the food bar is adjusted by the X-ray scanner and / or the frequency of the images.
- the values are stored individually and as a function of their position along the longitudinal axis of the food bar in a computer unit connected to the X-ray scanner as a curve. The values are integrated over the width of the respective scanning disc. All 5000 values are then added (eg 416325)
- the curve ⁇ , 1 - n (x) is then integrated until the desired number of readings (31224) is reached. This results in the length to be separated per portion. This process is preferably repeated piece by piece until the entire food bar is divided into portions of the desired weight.
- Food bars are handed over to the slicer and there cut into several portions (e.g., 13) based on the data obtained, each serving containing several food slices.
- each portion is transferred to the packaging machine 4 and packaged. Thereafter, each package is weighed with the checkweigher 5.
- Step 1 can therefore be omitted at the second food bar or when once the total weight of all portions obtained from a food bar has been determined.
- the individual weights or the total weight are used for calibrating the transmission scanner and / or the evaluation device. LIST OF REFERENCE NUMBERS
