Abstract

The invention relates to a cutting tool and to a method for processing a slaughtered animal (14) transported in a suspended manner along a conveyor. In order to guarantee a precise opening of the slaughtered animal, the invention provides a cutting tool which has a pelvic bone blade (34) in addition to a rotating cutting blade (30). Either the cutting blade or the pelvic bone blade is used depending on the type of processing.

Description

[1]
2 Method for carrying out at least one processing step on a slaughter animal, and cutting tool The invention relates to a method for performing at least one processing step in at least one processing station on a slaughter animal hanging from the track of a moving conveyor in a slaughter line by scanning the slaughter animal, digitizing the scanned data, and feeding the latter to a control system of a handling device, such as a robot, which is used to carry out the at least one processing step. The invention further relates to a cutting tool with a cutting blade rotating about an axis of rotation, e.g. a cutting cylinder, which is operated by a handling device such as a robot and which partly is surrounded by a protective hood that is pivotable about the rotational axis and partly covers the cutting blade.
The German periodical: Fleischwirtschaft 8/2005, pages 25 to 28, Schmidt, F.:
"Roboter toppen Spezialmaschinen" [robots surpass specialized machines] and US 6 623 348 Al disclose methods of this type. In this, slaughter swine are being conducted through a measuring station at the beginning of a robot line, where one or several laser scanners serve to digitize a surface profile of the body of the slaughter animal. Subsequently a robot (handling device) can be operated on the basis of the digitized values to pinch off front feet, cut free the rectum, dissever the aitchbone, and open the abdominal wall and the sternum. The individual operations take place in separate processing stations. The slaughter animal is continuously being conveyed during the individual processing steps, so that work is performed on the slaughter animal during continuous operation, i.e. the tool guided by the robot is moved synchronously relative to the transport motion of the slaughter animal conveyor.

[2]

Known from EP 0 594 791 B1 are a method as well as an apparatus for cutting open the body of an animal. When opening the abdominal wall and the sternum, the viscera are kept away from the abdominal wall. For this purpose a cutting tool possesses a mandrel that can be positioned relative to the tool.
For the purpose of ensuring proper front leg positions when slaughtering swine hanging from their hind legs, EP 1 182 933 B1 describes positioning means with an essentially solid positioning element that is driven between the front legs of the slaughter animal.
A cutting tool with a rotating blade is described in DE 10 2004 022 346 B2.
Here the cutting blade is surrounded by a protective hood, which is rotatable relative to the cutting blade. In a retracted position, the cutting blade cuts into the slaughter animal, and after the incision has been accomplished, the hood is adjusted in the direction of the slaughter animal.
From WO 2014/025250 Al, which is more dated but was not pre-published, are known a method and a device that facilitate the severing of the pelvic bone and the centric opening of the abdominal wall and the sternum. Used for this are a rotary cutting blade as well as a pelvic-bone knife, which may originate from a protective hood that partially encloses the cutting blade.
The objective of the present invention is to further develop a method and a cutting tool of the above-mentioned types in a manner that facilitates highest quality when opening the pelvic bone of a slaughter animal.
To meet this objective, the invention essentially recommends that from the cutting tool or from the protective hood extends ¨ along the radial direction relative to the rotational axis - a knife, such as a pelvic-bone knife, for opening the pelvic bone of the slaughter animal, that the pelvic-bone knife or the protective hood with firmly mounted pelvic-bone knife is revolved or pivoted into a first position, in which as the first processing step the pelvic bone of the slaughter animal is
[3]

opened with the pelvic-bone knife, and that after the opening of the pelvic-bone, the pelvic-bone knife or the protective hood with the firmly mounted pelvic-bone knife is rotated or pivoted into a second position, in which as the second processing step the abdominal wall and the sternum of the slaughter animal are severed in the centre by means of the rotating cutting blade.
In contrast to the state of technology, the pelvic bone or aitchbone is not opened by a rotating blade, but by means of a pelvic-bone knife, which is arranged rotatable or pivotable about the rotational axis of the rotating cutting blade. Preferably the pelvic-bone knife is mounted rigidly on the protective hood, which is located above the circular knife, and by means of the protective hood is rotated through an angle of 1800 < a < 140 , preferably 160 , so that the fixed pelvic-bone knife or aitchbone cutter is in a first position, in which it is possible to open the aitchbone (pelvic bone) of the slaughter swine.
After the opening of the aitchbone, the protective hood is rotated back into a second position, to drive a finger that is arranged on the protective hood behind the pre-opened abdominal wall and to open the latter and the sternum in the centre by means of the rotating cutting blade.
As a further development of the invention it is intended that the protective hood and/or the pelvic-bone knife can be adjusted using pressure cylinders such as pneumatic cylinders. Independent of this, the pelvic-bone knife is pivotable about a third axis, which extends outside of the cutting tool.
As a further development of the invention, the cutting tool together with the pelvic-bone knife are rotatable as a unit about a second axis that extends at a distance from the rotational axis, which provides the necessary freedom of movement for the severing of the pelvic bone.
[4]

Independent hereof, when the protective hood or the pelvic-bone knife are in the position for severing the pelvic bone, the abdominal wall, and the sternum, they should be actively non-adjustable, i.e. in comparison to the state of the art should not perform any purposeful movements.
Further details, advantages, and features of the invention are not only found in the claims and the characteristic features listed therein - individually and/or in combination ¨but also in the following description of exemplary embodiments illustrated in the figures.
The figures show:
Fig. 1 shows a schematic diagram of a processing station, Fig. 2 shows a top view of the processing station of Fig. 1, Fig. 3 shows a cutting tool in a position that opens the aitchbone, and Fig. 4 shows the cutting tool of Fig. 3 in a position that opens the abdominal wall and the sternum.
Figs. 1 and 2 illustrate a processing station 10, in which a slaughter animal 14 is processed by means of a robot 12. As an example, this may be a swine being transported while hanging by its hind legs 16, 18. The hind legs 16, 18 are connected to hooks 20, which are slidably disposed on a pipe track 22 of in particular a continuous conveyor. Naturally other types of conveyors can also be used. In this respect, the reader is referred to technologies in slaughter lines known in the art.
The belly side 24 of the swine 14 is facing the robot 12, which is controlled using digitized scanning data, which may be extracted from scanning data of the swine 14 that is not =
[5]

illustrated but is well known in the state of the art. For this, the swine is carried past one or several laser scanners, which scan at least those regions of the swine 14 that are to be worked on.
In the processing station 10, in particular in the work area 25, cross-hatched in Fig. 2, the aitchbone, abdominal wall, and sternum of the swine 14 are opened. This is performed by means of a cutting tool with a cutting blade 28, such as a saw, rotating about a rotational axis 26, and a pelvic-bone knife 34 originating from the cutting tool. The cutting blade 28 is surrounded by a protective hood 30, which is pivotable about the rotational axis 26. From the protective hood 30 extends along the radial direction the rigidly mounted pelvic-bone knife 34. The cutting blade 28 with the protective hood 30 originate from an arm 32 of the robot 12, in order to be able to carry out the processing of the swine 14 to the desired degree. The robot 12 is enclosed in a protective covering 33 to meet hygiene requirements.
The processing of the swine 14 by means of the robot 12 takes place during the transporting of the swine 14, i.e. while it is being conveyed through the work area 25. In order to rule out any change of position of the swine during the processing and the transport through the work area 25, which would result in a lack of precision in the processing of the swine 14, a support 35 against the swine's backside 38 ensures a stable position. In this, the support 35 moves synchronously with the conveyor. In the embodiment example, the support 35 is embodied as a circumferential flat belt. In accordance with the illustration in Fig. 1, several corresponding belts or supports 35, 40, 42 may be provided to provide support for the swine 14 in several spaced apart areas.
Fig. 3 shows the cutting tool in a first position, whereby the aitchbone of the swine 14 is not opened using the rotating cutting blade 28 but rather using the pelvic-bone knife 34 that is rigidly arranged on the protective hood 30, whereby the protective hood 30, which is arranged rotatably about an axis 26 over the rotating cutting blade 28, together with the rigidly mounted pelvic-bone knife 34 is rotated about an angle
[6]

of nearly 180 (160 ), so that the firmly mounted pelvic-bone knife 34 is in its first working position and consequently the aitchbone (pelvic bone) of the swine 14 can be opened.
After the opening of the aitchbone, the protective hood 30 is rotated back into a second position, which is illustrated in Fig. 4, to run a finger 36, which is arranged on the protective hood 30, behind the pre-opened abdominal wall, in order to open the latter and the sternum in the centre by means of the rotating circular knife 28.
The use of a pelvic-bone knife 34 facilitates cutting of the highest quality, since the pelvic-bone knife 34 during the opening of the pelvic bone choses the path of lowest resistance, namely through the area of cartilage joining the pelvic bone. As a result there is no damage to high-grade meat cuts.
