APPARATUS AND PROCEDURE FOR FRESH CUTTING
FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION This invention relates to an apparatus and method for cutting at least part of a tenderloin in a suspended carcass half.
BACKGROUND OF THE INVENTION
After mid-splintering of a carcass on a slaughter line, the two associated carcasses are transported further on the line suspended on hinges. The carcasses may be interconnected in the stern, in a piece of the nape of the neck, or may be completely separate. In some cases, the head can be cut off early on the slaughter line for hygienic reasons.
The present invention relates to free cutting of the tenderloin from the carcasses after these are centered.
When cutting the tenderloin from a carcass half on a slaughter line, it is essential that the cutting takes place very precisely. Today this is done manually. Stew has a relatively high selling price, but assumes that the tenderloin is properly cut from the carcass. It is thus essential that the sirloin is not damaged during the cutting and that unwanted tendons and obstructions are not cut together with the sirloin. Much of the precision of the cut depends on the starting of the cut at precisely the right place. Thus, in automatic cutting, it is very important to be able to make a very quick and correct positioning of cutting tools and carcasses relative to each other before starting cutting.
The rate at which haircut is performed is especially significant given the very high rate at which carcasses are treated on a slaughter line. Often 350 or more animals are slaughtered per hour on the slaughter lines, which corresponds to a stroke time from arrival at a treatment station to the arrival of the next carcass of about 10 2 DK 2009 00210 U3 sec. Within this time, automated equipment must be up to several processing processes. This thus places great demands on the speed at which the cut is done. Furthermore, the high tempo means that the fault tolerance is low, ie. that in practice there is no time to correct an inadequate or imprecise cut. Thus, a very stable and high level of precision is required in the cutting.
The presently used method of cutting a tenderloin can be done by manually cutting the tenderloin from the carcass with a knife or the like. This type of haircut causes relatively large disparity in the freshly cut fillets. It is also a time-consuming procedure that also exposes the operator to danger as the cutting pattern is complicated.
An often used method for cutting off the sirloin in a carcass is to cut the sirloin, cool the carcass and an operator then extract the sirloin manually. The carcass is cooled after the pre-cut to allow the tenderloin to maintain its characteristic droplet shape. Evidently, the manual interaction between the operator and the carcass is extremely inappropriate given the high pace of the slaughter line. Furthermore, the manual extraction of the sirloin is difficult to control precisely, and therefore an undesirable variation in the quality of the sirloin which is extracted manually occurs.
Thus, there are a number of drawbacks to the known techniques for cutting tenderloin in a carcass. First, the known techniques involve a manual step. This makes them sensitive to human error and significantly limits the speed at which the cut can be made. In addition, the precision of the cut can fluctuate from operator to operator and therefore results in disparate fillets requiring varying degrees of finishing. In addition, during the manual step, the operator is exposed to a not insignificant risk which increases in rate 3 DK 2009 00210U3 at an increased rate of cutting. Thus, it is difficult or impossible to increase efficiency without compromising safety and / or precision.
The foregoing disadvantages of the known techniques mean that there is a need to provide a new, safer, more accurate and faster method and a corresponding apparatus for use in cutting a tenderloin from a carcass.
The object of the present invention is wholly or partly to alleviate the above-mentioned drawbacks and to fulfill the stated need. More specifically, it is an object of the present invention to provide an apparatus which ensures rapid, accurate and uniform cutting of carcass fillets.
It is further an object to provide an apparatus which makes cutting a tenderloin from a carcass independent of manual steps.
It is a further object of the present invention to provide an apparatus for minimizing the risk associated with cutting a tenderloin from a carcass, including the risks associated with unilateral repetitive work.
Finally, it is an object of the present invention to provide a method of cutting at least part of a tenderloin in a suspended carcass half, which may benefit from the aforementioned apparatus provided.
SUMMARY OF THE INVENTION The present invention is new and peculiar in that the apparatus comprises a fixture with a sham bend for positioning and supporting the carcass half at its shambles, and the apparatus further comprising a cutting assembly having a sharp edge that curves across the edge. and a moving device for the cutting unit for moving the cutting unit with the sharp edge at the front during cutting of at least part of the tenderloin in a slaughtered half-body trapped in the pubic position. By "transverse arches" is meant that the sharp edge is arranged with its pointed edge arranged in a first direction, and that the sharp edge describes a curve when the sharp edge of the projection is projected on a plane which is placed in the right direction angles on the first direction.
By providing an apparatus with a fixture comprising a poultry catcher, it is achieved that a carcass from which the tenderloin is to be freshly cut can be positioned in the fixture relative to the carcass's pubic bone. Since the pubic bone is anatomically in a fixed position relative to the tenderloin, it is possible to determine from the position of the pubic bone the tenderloin. If you have thus fixed the carcass in relation to its pubic, you know at exactly what distance and direction from the fixing point any possible cutting of the tenderloin should be started. The apparatus of the present invention further comprises a cutting assembly adapted to cut the tenderloin, ensuring that the tenderloin cutting can be done correctly. It should be mentioned that from the location of the pubic bone one can predict the location of other anatomical parts besides the tenderloin. Thus, positioning a carcass at its pubic site may be useful in a variety of situations other than by cutting tenderloin.
The pubic catch may have an upper, preferably sharp edge, inclined downwardly against an opposite upward edge, and the apparatus may comprise a lifting device for raising the pubic catch to a predetermined supporting position or a lowering device for lowering the suspended slaughter half body to support the pubic leg of the pubic leg. At the sharp edge it is achieved that as the pubic bone slides along it, the edge cuts through any tendons, cartilage or the like which may be outside the pubic bone. Thus, the edge cuts all the way to the bone itself, thereby ensuring a more precise placement of the pubic bone in the pubic bone. The opposite upward edge ensures a simple and stable retention of the pubic bone in the correct position and makes it easy to release the carcass from the fixture after the cut of the tenderloin and to carry it to any subsequent treatment on the stroke line. The ability to lift the pubic penis or lower the carcass makes it easy to position the pubic bone correctly in the pubic penis. The possible lifting and lowering devices may e.g. be constructed by the burst of automatically controlled pistons or the like.
The cutting assembly may comprise a hollow cylinder having an inner surface and an outer surface, and with the sharp edge at one end, which end may be obliquely cut and have sharp edges on the oblique cuts. The optional bevel cutting of the cylinder facilitates cut-off as the cutting unit can be inserted towards the tenderloin with the front portion of the bevel edge just above the tenderloin and the cut portion off the top of the tenderloin. Thus, the top of the sirloin can be cut without damaging the rest of the sirloin.
The sharp edge may have a location in extension of either the inner or outer surface of the cylinder, and this location of the sharp edge may be varied on different portions of the inclined cuts. Thus, the sharp edge may e.g. is placed in extension of the outer surface of the cylinder where the sharp edge must cut through meat or other soft tissue. This provides an accurate and effective cut from the surrounding soft tissue. Conversely, the sharp edge may be positioned in extension of the inner surface of the cylinders where the sharp edge is to cut along hard tissue, such as e.g. bones. This avoids the sharp edge cutting into the hard tissue and possibly getting stuck in this.
The moving device may be arranged to move the cutting unit in a predetermined path and direction with respect to the shin bone, such that the sharp edge intersects at the transition between the carcass half and the tenderloin in the carcass fracture plane. This allows great precision and speed in the process. The moving device may e.g. be an industrial robot of common type, such as with 6 degrees of freedom.
The cutting assembly may be connected to a movable portion of a manipulator, and the movement and direction of the cutting assembly relative to the sham catch / fixture may be programmed into the manipulator's control unit.
The cutting assembly may comprise a tendon cutter adapted for cutting tendons and other surrounding tissues at the tenderloin. This can contribute to correct and effective cutting of the tenderloin, as the tendon cutter can quickly cut tissue as the sharp edge of the cutting unit can be difficult to reach.
The tendon cutter can also be arranged movably on the cutting unit. This allows for simple coordination of tendon cutting and cutting and makes the tendon cutter flexible in relation to the cutting unit itself.
The moving device may be located at the side of the fixture intended for insertion of the carcass half into the fixture.
The fixture may comprise an upper displacement assembly adapted to fix, at mechanical pressure, an upper portion of the carcass between the upper displacement assembly and the sham bone. Such fixation at the positioning point prevents displacement of the positioned anatomical part. That is, fixation can help keep the pubic bone in the pelvic area and that there is no movement in the carcass when the cut is performed.
The upper shear assembly may further comprise a abutment plate, and the sham baffle may comprise means for moving the sham baffle toward the abutment plate to a predetermined position. In this way, the fixing is achieved in a simple and secure way.
The fixture may further comprise a lower fixing assembly which engages the backbone of the carcass. This will help to secure the correct position in the correct position and prevent fluctuations of the lower part of the carcass.
Further, the lower fixing assembly may be movable between an opened bed and a fixing bed, whereby the fixing unit exerts a restraining force on the carcass spine. Hereby, the desired fixation is obtained in a simple manner.
In addition, the lower fixing assembly may be designed as a movably mounted L-profile plate suitable for gripping its spine. In that the lower fixing assembly engages an anatomical part of the carcass, such as e.g. backbone, the fixation is made more precise and stable.
The apparatus may comprise a fixture for two carcasses suspended in a hanger, which fixture has a sham catch for each of the carcasses.
The fixture may be arranged movably between a first position which substantially corresponds to the course of the suspended carcass transporter and a second position where it is displaced in the direction of the cutting assembly. This may be advantageous since the fixture thus e.g. can be cleaned in a retracted position and used for treating carcasses in an advanced position. Thus, different steps can be physically separated, which can allow for improved hygiene and easier workflows.
The invention further relates to a fixture for a slaughtered half-body or a rear part thereof. The fixture is characterized in that it comprises a sham catch for positioning and supporting the carcass at its pubic. The fixture has the above advantages in terms of positioning of tools and carcass / carcass part in relation to each other. The fixture can be used in the treatment of carcasses with various tools or machines, especially where the treatment takes place in the hindquarters of the carcass. The fixture can be used for automated processing of ham from carcasses, e.g. in connection with cutting of the tailbone, tendons, blubber, etc.
In one embodiment, the fixture may comprise an upper, preferably sharp, edge with a slope towards an opposite upward edge.
A sham trap for use in the present invention may comprise an upper, preferably sharp edge, inclined downwardly against an opposite upward edge. This is an advantageous embodiment of the shame trap.
A cutting assembly for use in the present invention may comprise a hollow cylinder having an inner surface and an outer surface, and having the sharp edge at one end, which end may be obliquely cut and have sharp edges on the oblique cuts. This is an advantageous design of the cutting unit.
A method for cutting at least part of a tenderloin in a suspended carcass half is further described, characterized in that the carcass half is brought into contact with a sham bone in a carcass half of the carcass; a relative vertical and possibly horizontal movement is made between the carcass half and the pubic penis so that the underside of the pubic bone and the upper side of the pubic penis come into contact with each other and the pubic bone descends into a depression in the pubic penis whereby the carcass half is positioned; and that a cutting unit having a sharp edge which curves transversely of the edge by means of a moving device is moved with the sharp edge at the front during cutting of at least part of the tenderloin. In such a method, the carcass is positioned relative to its pubic bone and thus the position of the tenderloin is known by virtue of its fixed anatomical position with respect to its pubic bone. Thus, since the position of the sirloin relative to the shank bone is known, the cutting of the sirloin by using the cutting unit can be started in the right place.
The cutting assembly for use in the above method may be moved in a predetermined path and direction with respect to the shin bone, such that the sharp edge intersects at the transition between the carcass half and the tenderloin in the carcass fracture plane.
The cutting unit may be formed with a cylinder having a sharp edge and a tendon cutter may be arranged movably on the cylinder. These characteristics of the cutting unit can improve and simplify the cutting operation similar to the corresponding properties of the apparatus described above.
In the above method, the sirloin can be cut off by sliding the cutting unit downwardly into the head of the sirloin, rotating the cutting assembly so that the head of the sirloin is cut freely, moving the cutting unit to a downward position, and moving the cutting unit downwardly downwardly and downwardly thereby activating so that the tenderloin is completely cut off over a substantial portion along the backbone.
This cutting method first ensures proper cutting of the head of the sirloin, after which the rest of the sirloin is cut.
The above method may comprise a step after the positioning and before the cut, where the carcass is fixed using one or more aggregate (s).
Such fixation may be advantageous in ensuring that the carcass is retained in the fixed position and does not swing or otherwise move during the cut.
The above method may comprise a step after cutting a portion of the sirloin, where the sirloin is automatically pulled free and transported away, for example for subsequent packing. Such automatic transport streamlines the slaughter line workflow while helping maintain good hygiene, avoiding manual steps.

Detailed description of the invention
An apparatus according to the invention comprises a fixture, a cutting unit and a moving device. The FIG. 1 for two slaughter half bodies has two sham bumps 2 with a sharp edge 3 and an upward edge 4 and an upper displacement assembly 5 as well as a lower fixing assembly 6. Both assemblies are movably arranged. The upper shear assembly 5 is movable between a fixing bed close to the shank 2 and an open bed away from the shank 2. The lower fixing unit 6 is movable between an open bed where the two L-shaped plates are turned forward and located sit close to each other on the front of the fixture and a fixed bearing where the L-shaped plates are turned back towards the back of the fixture. Furthermore, the sham catch 2 can contribute to the fixation by being able to move between an open bed away from the upper displacement assembly 5 and a fixing bed towards the upper displacement assembly 5. In FIG. 1, both assemblies 5 and 6 and sham trapping 2 are shown in their fixing bed. The movement of the aggregates 5 and 6 and the shank leg 2 is preferably carried out by means of hydraulic pistons and can be coordinated so that the carcass is fixed quickly and accurately. Further, within the idea of the invention, pneumatics or mechanical conveyances may be used.
When applied to a slaughter line of a preferred embodiment of the invention, a carcass, consisting of two carcasses, typically suspended in the rear of hinges or hooks, arrives at the fixture 1 after which the horizontal movement of the carcass is stopped. The carcass is then brought into contact with a poultry catcher 2 and lowered so that the carcass sham is moved along the carcass catcher 2 until it reaches an edge of the carnivorous catcher 2. Thereafter, the cutting is commenced in a predetermined direction and distance from the catcher catcher 2. In another embodiment, the carcass is brought into contact with sham trapped 2 by lifting sham trap 2 up against the carcass sham. In yet another embodiment of the invention, the horizontal movement of the carcass is not stopped upon arrival at fixture 1. On the other hand, fixture 1 is moved so that it accompanies the carcass and thus the cutting is performed while both the carcass and the fixture are in motion. Positioning and possible fixing can take place during the movement, as the fixture is essentially moved at the same speed and direction as the carcass, and the two are therefore virtually not moving in relation to each other, but exclusively in relation to the surroundings. Such free-range cutting can be advantageous in order to increase the speed at which the carcasses are processed and transported on the slaughter line.
The sham catch 2 is in FIG. 1 shown as consisting of a right and a left part. These two parts are mirror images of each other and are both shown with a sharp edge 3 and an upward edge 4. Both the sharp edge 3 and the upward edge 4 are special parts of the preferred embodiment and thus may be omitted. However, the sharp edge 3 and the upward edge 4 are particularly advantageous in that they allow the carcass of the carcass to slide along the sharp edge 3 until the pubic bone rests at the upward edge 4. Hereby the sharp edge 3 intersects through any. tissue which may surround the pubic bone, thus contributing to the correct positioning of the pubic bone in the pubic bone 2. The pubic penis 2 will typically be made of steel and may be pivotally connected to the fixture. The sham catch 2 may comprise means for displacing or rotating the sham catch 2 in different directions. Such means may be, for example, hydraulic pistons or pneumatic equipment. The sham trapped 2 can e.g. may be arranged to be displaced against a slaughter half body located at the fixture 1. The sham catch 2 may also be arranged to be movable back and forth with respect to the fixture 1 and possibly also to rotate about a given axis. An embodiment of slidable and rotatable shingles catch 2 is illustrated in FIG. 6 and further described below. However, the sham catch 2 may be formed in other ways, e.g. as one continuous piece of metal, without thereby falling outside the scope of the invention.
The upper displacement assembly 5 is shown in FIG. 1 shown as being two large, curved abutment plates. The upper displacement assembly 5 may comprise means, for example hydraulic pistons, for displacing and / or rotating the upper displacement assembly 5. For example, the upper displacement assembly 5 may be rotatable about an axis substantially corresponding to an anatomical portion of a suspended carcass, e.g. the spine or leg. Such rotation about a displaced axis can be obtained by the upper displacement assembly 5 comprising pivoting means where two parallelograms are displaced relative to each other, e.g. by means of hydraulic pistons such that the upper displacement assembly 5 rotates about an axis outside the displacement assembly 5. Such a preferred embodiment of the upper displacement assembly 5 is illustrated in FIG. 7. Turning about an offset axis can also be achieved in other ways. The upper shear assembly 5 will typically be of metal, such as steel, but may be formed in ways other than the one illustrated. Furthermore, the upper displacement assembly 5 can be completely omitted.
The lower fixing assembly 6 is shown in FIG. 1 shown as two L-shaped plates movably arranged on the fixture 1. The lower fixing assembly 6 is typically made of steel, but may be completely omitted or formed in ways other than the one illustrated.
Using a preferred embodiment of the apparatus, as shown in FIG. 1, fixation of the carcass begins when the pubic bone rests in the pelvic prisoner 2. This fixation is carried out by moving the upper shear unit 5 against the pestle catch 2 and thus fixing the carcass between the upper shear unit 5 and the pavement prisoner 2. upper displacement assembly 5 to promote fixation. In addition, the lower fixing assembly 6 is moved towards the carcass and possibly grips its spine. By this fixation it is achieved that the vertical position of the carcass can be used and maintained during the cutting of the tenderloin. Subsequently, the cut of the sirloin itself is started, which will be described in detail in a later section. After the cut-off is complete, the aggregates 5 and 6 and possibly the pubic trapped 2 are moved to their open bearings and the carcass can be lifted up by the pubic trachea 2 and moved further along the slaughter line. In another embodiment, the sham trap is lowered to release the carcass. Using another preferred embodiment of the invention, positioning, fixing and cutting are performed in the following steps, here exemplified by two carcasses: The carcasses arrive at the apparatus of the invention; the fixture 1 is advanced to an advanced position; the upper shear assemblies 5 displace against each slaughter half body; the sham bones 2 are displaced toward the carcasses; the pubic prisoners 2 are displaced along the slaughter half bodies until the pubic prisoners 2 come into contact with the pubic half body; the sham legs 2 are displaced inwardly so that the sham legs slide along the sharp edge 3 and end to rest at the upward edge 4; the carcasses are optionally lifted, e.g. carried by the prisoners of shame 2; the upper shear assemblies 5 and the shingles are rotated so that the inside of the carcasses is exposed; optional lower fixing assemblies 6 fix the lower portions of the carcasses; cutting of the sirloin begins. In this second preferred embodiment, the insides of the carcasses are turned and exposed only after their pubic bones are trapped in the pubic prisoners.
In FIG. 2 is a side view of an apparatus according to the invention. The apparatus comprises a fixture 1 with an upper displacement assembly 5 and a lower fixing assembly 6. In addition, the rear part of the apparatus is also seen in this illustration.
In FIG. 2, the fixture 1 is shown in an advanced position. In a preferred embodiment, the fixture 1 is arranged movably between a first position substantially corresponding to the course of the slaughter line and a second, advanced position, where it is displaced in the direction of the cutting unit and where the cut of the tenderloin can take place. Advantageously, the movement of the fixture 1 may be effected by the use of pistons, e.g. driven by hydraulics or pneumatics. Mechanical conveying means may also be used.
In FIG. 3, a cutting assembly 7 according to the invention is illustrated. The cutting assembly shown is cylindrical and has a cut end 8 with a sharp edge 9.
The cutting assembly 7 is shown in FIG. 3 illustrated as an oblique cut cylinder, but may be formed in other ways. The sharp edge 9 of the cutting unit 7 can, as shown in FIG. 3, be on the beveled end 8 of the cutting assembly 7. In other designs of the cutting assembly 7, the sharp edge 9 may be placed at any suitable location on the cutting assembly 7. In a cylindrical configuration of the cutting assembly 7, the sharp edge 9 may be placed in extension of either the inner or outer surface of the cylinder. This location of the sharp edge 9 can be varied on different parts of the cylinder to achieve proper cutting in surrounding tissues of various kinds, e.g. bones, tendons and muscles. The cutting assembly 7 may comprise a tendon cutter adapted for cutting tendons and other surrounding tissue at the tenderloin. The tendon cutter simplifies the cut of the tenderloin and can optionally be mounted on the cutting unit 7. The cutter can be designed as a sharp blade, e.g. a rotatable blade or a movable knife. Alternatively, the tendon cutter may be designed as a cylinder with a cutting portion. Such a cylinder may, for example, lie on the outside of a cylindrical cutting assembly 7 and be displaced relative thereto. This results in an additional cutting effect in addition to the sharp edge 9 of the cutting unit 7. Finally, the cutting assembly 7 may be connected to a manipulator {not shown). Automatic control of the cutting, e.g. using a manipulator can both make the cut faster, more accurate and less dangerous for any staff involved. The manipulator can e.g. be a robotic arm.
16 DK 2009 00210U3
Using a cutting assembly 7 of the preferred embodiment illustrated in FIG. 3, cutting is started by sliding the cutting unit 7 obliquely into the head of the fillet. Hereby the head of the fillet will be at the obliquely cut end of the open cylinder of the cutting assembly 7. Next, the cutting unit 7 is rotated so that the head of the sirloin is cut freely and the cutting unit 7 is moved to a downward position. Finally, the cutting assembly 7 is moved down the tenderloin at the same time as any tendon cutter is activated so that the tenderloin is cut over a substantial distance along the backbone.
In FIG. 4, another embodiment of a cutting assembly 7 according to the invention is illustrated. The cutting assembly shown is cylindrical and has a cut end 8 with a sharp edge 9.
In FIG. 5, an embodiment of a fixture 1 according to the invention is shown. The fixture includes sham catches 2, upper shear assemblies 5, a lower fixing assembly 6, and a cylinder 10 adapted to displace fixture 1. Sham catches 2 are adapted to be able to be moved up and down on fixture 1 and can further be folded and folded by means of cylinders. . The sham bones 2 are further illustrated in FIG. 6a-6c, wherein FIG. 6a and 6b show the sham baffle 2 in a collapsed state in which the central piston 11 is ejected and in which figs. 6c shows the sham bean 2 in an unfolded state where the central piston 11 is compressed. In FIG.
6c is also seen part of the fixture 1 on which the sham legs catches are mounted. An upper displacement assembly 5 is further illustrated in FIG. 7a and 7b. The upper displacement assembly 5 shown can be rotated about an offset axis by means of the double parallelogram type rotary means 12 shown, and by using e.g. hydraulic pistons.
In FIG. 8a-8d, photographs of a prototype of an apparatus for cutting a tenderloin can be seen in successive steps. A set of carcass halves 14 is suspended in hinges and spread out to expose the inside of the carcasses, e.g. to provide easy access to the tenderloin. An industrial robot 13 was used as a moving device for the cutting unit 7, which in the illustrated prototype was a so-called chopping pipe. In FIG. 8a, the cutting assembly is in a position at the head of the sirloin in one of the two carcasses. In FIG. 8b, the cutting of the sirloin head is started by moving the cutting assembly 7 of the robot 13 into the slaughter half body to cut the head of the sirloin. In this initial part of the cut-off process for the sirloin, the cutting edge is moved at approximately right angles to the inner surface of the carcass to dig into the carcass at the head of the sirloin to substantially cut the head of the sirloin. In FIG. 8b is also seen the upper displacement assembly 5. This upper displacement assembly 5 provides a fixed abutment for the respective carcasses to facilitate cutting of the tenderloin. FIG. 8c illustrates a third step in which the cutting assembly 7 is tilted slightly by the robot 13 for downward movement of the cutting edge to cut the head 15 of the fillet and a portion of the fillet 16. In FIG. 8d, a subsequent step can be seen in which the robot 13 moves the cutting assembly 7 down along the backbone 17 to cut off a portion of the tenderloin. The robot 13 will then move the cutting assembly 7 correspondingly to the second slaughter half 14 to cut the tenderloin in the second slaughter half in a similar process. In initial testing of the concept, an ABB industrial robot of type 140 was used with an IRC5 type lubrication, but other types of robots and other types of suitable equipment, such as automatic and semi-automatic actuators, can be used as an alternative.
Although the invention has been described above in connection with preferred embodiments of the invention, it will be apparent to one skilled in the art that several modifications and improvements are possible without departing from the spirit of the invention as defined by the following claims. For example, the cutting unit may be a Wizard knife, ie. a knife with a rotating blade, or any other suitable means.
Although it is presently preferred to cut the tenderloin from a suspended carcass, it is evident that it will also be possible to cut the tenderloin from a carcass that is not suspended but instead arranged more or less horizontally, such as lying on a transporter.
Further, the person skilled in the art will understand that the directions described, etc., are relative, so that terms such as "vertical", "horizontal" should not necessarily be understood in a strictly literal sense, but broadly as relative terms. Furthermore, those skilled in the art will understand that kinematic exchange is often possible.
