Abstract
Description
- The present invention relates to a device for sorting pieces of meat, such as middles, comprising a fixed conveyor belt with means for measuring the thickness of the fat layer and means for measuring the weight of the individual pieces.
- Such devices are known in the meat-processing industry. The pieces of meat are placed with the fat layer facing down on the conveyor belt, held still at the device for measuring the fat thickness, and a sensor, which is known per se, is subsequently forced into the fat layer from the bottom up through the supporting face. The pieces of meat are then conveyed further for measurement of their weight. On the basis of the measuring results, the pieces of meat are subsequently divided by hand into specific quality grades, ranging from lean to fat.
- Such an operation for the sorting of pieces of meat is very labour-intensive and is also difficult for the personnel, who always have to watch both the upper and lower limit of the fat layer and the weight of the pieces of meat for various quality grades. Mistakes are bound to be made, so that pieces of meat can go into the wrong grades.
- The object of the invention is therefore to produce a device for sorting pieces of meat, avoiding these disadvantages.
- This object is achieved according to the invention in that the device comprises a movable conveyor belt which connects to the fixed conveyor belt in the direction of conveyance, is provided with an operating device, and can be swung between a number of positions, in each of which another receiving element is connected to the movable conveyor belt, and a computer which receives input signals from the thickness measuring means and from the weighing means, and which, on establishing one of a number of quality grades, transmits appropriate output signals to the operating device for the purpose of taking the movable conveyor belt to the position suitable for the piece of meat to which the input signals relate, in which position it connects to the receiving element corresponding to the established quality grade.
- With the device according to the invention, a middle lying within certain limits as regards weight and fat layer thickness is now fed to the correct receiving element by the swinging conveyor belt. The intervals between the middles are chosen depending on the speed of conveyance and the swinging speed of the swinging conveyor belt.
- The swinging conveyor belt can be designed in various ways. For example, it can be such that it swings in the horizontal and vertical plane, in order to convey the pieces of meat, such as middles, to receiving elements which are situated adjacent to and/or above each other.
- For division into four quality grades, there would then be, for example, two groups of two receiving elements laying above one another.
- For division into four quality grades, it is preferable for the device to be designed in such a way according to the invention that is comprises three conveyor belts, each swinging between two positions, the second and third of which connect to the first swinging conveyor belt in its first and second positions respectively, and each of which also has an operating device connected to the computer. Depending on the measured data, the computer now controls the movements of the three conveyor belts. The receiving elements are adjacent to each other in this embodiment and are formed, for example, by roller conveyors over which the sorted middles are conveyed further.
- According to another preferred embodiment, the device is designed in such a way that the fixed conveyor belt is double, each part comprising a device for measuring the thickness of the fat layer and in conveyance direction connecting to a conveyor belt part having vertical walls sloping towards each other in said direction, which are above said conveyor belt part and leave open a passage the width of a piece of meat, and behind that is a conveyor belt part with a weighing sensor.
- Since the middles always have to be held still for the thickness measurement, the working speed of the whole device is determined by the working pace of the thickness measuring device. If the measuring device with conveyor belt is now made double, the working speed of the sorting device can be increased.
- For the discharge of the middles which meet none of the programmed quality standards, the device is, finally designed in such a way that the second or third conveyor belt has a third position.
- The invention will now be explained further below with reference to the drawing.
- Fig. 1 shows the device according to a preferred embodiment of the invention, in plan view.
- Fig. 2 shows a sketch with quality grades for the middles from which bacon is made.
- In Fig 1 the device is designed with two
fixed conveyor belts 1 and 2, each provided with a device for measuring the thickness of thefat layer measuring devices conveyor belt 5 withguide walls 6 slanting towards each other, through which the streams coming from the measuring device are combined to one. - The middles then run over a known weighing
conveyor belt 7 with weighing device. - Connecting to the weighing
conveyor belt 7 in the direction of conveyance is a first swingingconveyor belt 8, which can be swung, e.g. in the horizontal plane between two positions. A second swingingconveyor belt 9 and a third swingingconveyor belt 10 are placed in both positions of theconveyor belt 8, connecting in each case. Theconveyor belts further conveyor devices 11 or packing or despatch stations connect for discharge of the sorted middles. The swingingconveyor belts measuring devices weighing device 7. This takes place by means of a computer. This computer contains a number of combinations of fat thickness and weight to each of which a quality standard is allocated. An example of a classification into quality grades, depending on the fat thickness and weight, is given in Fig. 2. The four quality grades I, II, III, IV found therein each correspond to one of the four positions of theconveyor belts conveyor belt 10 for the discharge of rejected middles. - A middle with a weight of 12.5 kg, but with too low fat thickness of, say, 8 mm goes into area I and is regarded as unsatisfactory in quality.
- The computer thus has fed to it the measured value of the thickness of fat layer and the weight, it always compares each combination with the quality standards, and it then controls the conveyor belts.
