ANI~AL CARCASS SUPPOXT FRAME AMD Dh~SSl~ MET~OD

FIE~D OF l~v~.~ lU~

The invention comprises an animal carcass support frame and dressing method.
p7.. 'KliKI 11 INI~ ART
Currently in a meat works animal carcasses are dressed manually by meat workers, which i5 labour intensive. Further ~ nication of the dreasing process is inhibited by the fact that no one animal carcass is ;~Pn~ in size and shape to another, and eUV~L in a conventional meat works chain carcasses are Sn~r~n~ from above in a way that allows for a relatively large amount of ~; L of the carcass so that a particular point on each carcass proceeding along the chain, such as the point at which the Y-cut iB begun, will never be in the same position from one carcass to the next.

S~MMARY OF INVENTION
The present invention provides a frame which supports a carcass and which presents it in a uniform way. The frame of the invention may be used to present a carcass ~ln; f~rmly to different m~-h;n~5 along a processing chain or in different ways to a stationary dressing machine, such as a robotic arm e~1;rr~
with various tools for example. The frame may hold the carcass to present it to each set of tools at a prs~csing station so that a number of operations can be carried out at the same station. The frame of the invention allows for the orientation ~o g610~14S ~ 1 9 5 5 2 9 or position of the carcass to be determined or maintained or altered with respect to the frame and hence with respect to other devices or objects.

The invention also provides a carcass dressing method using an industrial robot.

Preferably the rear frame part is pivotally mounted to the front fr me part along a substantially horizontal axis for ~ WO9G/02145 P~~
pivotal ~. l to raise and lower the rear frame part relative to the front frame part.

In broad terms in another aspect the invention _ _ C~5 an animal carcass support frame as ~r~5~rihr~ together ~ with an industrial robot comprising a robotic arm equipped with a cutting tool for dressing the carcass and p- U~L -' to carry out dressing operations on the carcass.

Preferably the robot is programmed to carry out at least the front Y-cut down the front legs and chest of the carcass.

The invention also comprises a cutting tool for equipping to a robotic arm of an industrial robot, the cutting tool being ~-nip~ table and operable under control of the industrial robot, comprising two parallel adjacent cutting blades reciprocally movable in the same plane each beside the other and a motor which drives the cutting blades, the cutting blades and motor being formed as a unit attachable to the robot arm, and means to attach the cutting tool to the robot arm.

In broad terms in a further aspect the invention comprises a method of dressing a carcass comprising s~1cp~n~; n~
the carcass in an inverted position from the front and rear hocks of the carcass, and carrying out dressing operations on the W096~ 5 F~ L~
carcass by an industrial robot comprising a robotic arm iqnirpod with a cutting tool for dressing the carca~s.

~ WO96/01145 ~ScKls~lON OF ~K~ KK~ EMBODIMENTS
Referring to Figs 1 to 4, the frame in~ a front part which _ Re~ a top transverse member 1 to which the carcass's front hocks are held by suitable clamps or spikes for example, or other means for holding the front hocks of the carcass. There are two downwardly ~Yt~n~; ng members 2a and 2b on either side and a lower transverse member 3 which forms a neck support part of the frame to support a carcass behind the neck or shoulders. The neck support member 3 is carried by vertical members 4a and 4b t~ copic~lly mcunted in the members 2a and 2b and controlled by hydraulic rams or similar to raise and lower the neck support part 3.

A rear frame part comprises a top transverse member 5 to which the carcass's rear hocks are held, again by suitable clamps or spikes or similar, which is pivotally connected to the front frame part at pivot points 7. Movement of the rear frame part is controlled by the hydraulic or pneumatic ram 8.

In use of the frame to support a carcass during dressing operations on the carcass, the front hocks of a carcass are first attached to the top transverse member 1 and the rear hocks of a carcass are attached to the top transverse memcer 5.
The frame is then used to position the carcass as desired. For example, the rear frame part may be elevated by the ram 8 to the position shown in Figs 2A and 2B to aid the draininq of blood from the neck cut and sticking. The rear frame part may then be wos6~02l4s F~ .~ L
dropped to the poaition shown in Fig. 3A and 3B BO that the stomach contents do not drain out of the o~50ph~gnc. After the oesophagus is clipped, the rear frame part may be raised to the intermediate position shown in Figs. 4A and 4B so that the carcass briskct region is horizontal. At this stage the front Y-cut may be carried out (see Fig. 5), the brisket flaps pulled back and the neck, shoulders and forelegs cleared. In this position further operations may be carried out including hock removal, belly oror~ti~n~ rear Y cutting and splitting of the brisket flap.

Pig. 5 shows the preferred ~orm frame together with an industrial robot comprising a robotic arm 10. The robotic arm is shown as a roof or ceiling mounted robotic arm or the arm 10 may be mounted from a beam above, but the robot may be of any suitable type such as a robot which stands on the floor, comprising two or more robot arms for example. The robot i& U5ed to make the dressing cuts in the carcass. The frame of the invention poaitions each carcasa in a substantially identical position when compared to conventional means of Sll~p~n~ing a carcass from a moving pnOC~CcinrJ chain for example. Thus the point at which the robot starts a cut such as the front Y-cut shown in Fig. 5, ic always in a similar spatial position. Fig.
5 shows the robotic arm 10 ; ng a cutting tool 11 on the end thereof comprising cutting blades 12 making the front Y-cut down the front legs and chest of the carcass. The robot may be ~ WO s6~02~4s p~UyL 1 to make other dressing cuts and Fig. 5 shows the robot arm making the front Y-cut by way of example.

Fig. 6 shows a pIefuLLud form cutting tool. The tool comprises two parallel adjacent cutting blades 13 and a motor within the cutting tool body unit 14 which drives the cutting blades 13. The motor may be connected to the cutting blades through a gearbox within the cutting tool body unit 14. The motor is controlled by the robot. When the motor is op~rPt~d, the cutting blades 13 reciprocate back and forth together in a cutting action. In the preferred form the cutting blades move with a rotary reciprocal action as indicated by the arrows in Fig. 6. This has been found most effective for cutting through the pelt of an animal carcass.

It is also preferred that the cutting blades 13 are cranked as shown, _ ~;ng a first cutting edge portion 13a and a second cutting edge portion 13b which has shark tooth shaped teeth. The shark tooth teeth point back towards the first blade portion 13a as shown.

In use the robot having the cutting tool of Fig. 6 mounted to the end of the robotic arm inserts the cutting tool through an initial puncture made through the pelt of the carcass.
The robot then energises the motor to cause the cutting blades 13 to operate, and the robot arm moves the cutting tool upwardly to make for example the front Y-cut as shown in Fig. 5.

In the preferred form cutting tool the motor is an air motor but it could alternatively be an eleatric or hydraulic motor for ex~ple.

The foregoing ~c~rih~c the invention in~~ ing ~
preferred form thereof. Alterations and I 'ifi~ati~n~ as will be obvious to those skilled in the art are intended to be incorporated in the scope hereof as defined in the following claims.
