Fat cover measurement device
The invention relates to a measuring device ( 18 ) for determining the thickness of a layer of fat of a meat product ( 12 ) comprising a premium cut part and a layer of fat, wherein the thickness of the layer of fat is determined in a contact-free manner. The invention also relates to a device for separating the layer of fat of a meat product from a premium cut part of a meat product by means of said type of measuring device, and to a method for determining the thickness of a layer of fat of a meat product and to a method for separating a layer of fat of a meat product.
1. An apparatus for separation of a fat cover of a meat product from a flesh component of the meat product, comprising:
a measurement device for automatic determination of the thickness of the fat cover, wherein the determination of the thickness of the fat cover takes place in a contactless manner; and
cutting device coupled to the measurement device for automatic separation of the fat cover from the flesh component in dependence on the thickness determined by the measurement device, wherein the cutting device comprises:
a cutting blade whose position is variable relative to a product support; and
a control unit for control of the position of the cutting blade in dependence on the thickness determined by the measurement device, wherein at least one travel profile is stored in the control unit in accordance with which the position of the cutting blade relative to the product support is to be set in dependence on a product feed.
2. The apparatus of claim 1 , wherein the determination of the thickness of the fat cover takes place optically.
3. The apparatus of claim 1 , further comprising a light detector for the detection of light reflected at the meat product.
4. The apparatus of claim 3 , wherein the light detector comprises a camera.
5. The apparatus of claim 1 , further comprising a light source configured to illuminate a region of the meat product.
6. The apparatus of claim 5 , wherein the light source comprises at least one light emitting diode.
7. The apparatus of claim 6 , wherein the light emitting diode is configured to emit light in the blue wavelength spectrum.
8. The apparatus of claim 1 , further comprising a transport device configured to transport the meat product through the measurement device.
9. The apparatus of claim 8 , further comprising a light source and a light detector disposed laterally next to the transport device when viewed in the transport direction.
10. The apparatus in accordance of claim 8 , wherein the transport device further configured to supply the meat product to the cutting device.
11. The apparatus of claim 1 , wherein the cutting blade is a cutter bar.
12. The apparatus of claim 1 , wherein the position of the cutting blade comprises the height of the cutting blade relative to the product support, wherein the travel profile comprises instructions for the height of the cutting blade along a length of the meat product.
13. The apparatus of claim 1 , wherein the position of the cutting blade is variable relative to the meat product.
14. A method for separation of a fat cover of a meat product from a flesh component of the meat product, comprising:
determining the thickness of the fat cover in a contactless manner;
setting a position of a cutting blade in dependence on the determined thickness of the fat cover in accordance with a preset travel profile and in dependence on a feed of the meat product, wherein the setting comprises setting the position in a direction transverse to the feed direction; and
with the cutting blade, separating the fat cover from the flesh component, wherein during the separating, the cutting blade is at the set position according to the travel profile.
15. The method of claim 14 , wherein determining the thickness of the fat cover comprises an optical measurement.
16. The method of claim 14 , wherein determining the thickness of the fat cover takes place during a transport movement of the meat product.
17. The method of claim 14 , wherein the meat product defines a length along the feed direction, the method further comprising determining the shape of the fat cover over the total length of the meat product at characteristic measurement points and by subsequent interpolation or extrapolation.
18. The method of claim 14 , further comprising comparing the determined thickness with thickness values that are to be expected for the meat product, and displaying an error message when the determined thickness deviates from the thickness values that are to be expected.
19. The method of claim 14 , wherein the meat product defines a length aligned in the feed direction,
wherein determining the thickness comprises selecting only a part of the length of the meat product, and measuring the thickness of the fat cover only at the part of the length, and
wherein setting the position of the cutting blade comprises selecting the preset travel profile only in dependence on the measured thickness taken only at the part of the length.
20. The method of claim 19 , wherein the part of the length is a frontmost part in the feed direction.
