Description

SYSTEM FOR DISCHARGING BOTH EDGES FROM A CUTTING FORM IN THE FANON OF A RUMINANT, LIGATURE POST OF HERBIERE AND METHOD OF LIGATURE OF HERBIERE

The present invention relates to the field of hygiene and ergonomics systems for slaughterhouse workstations, and relates in particular to a system for spacing the two edges of a cutout formed in the form of a ruminant, on a station of herbarium ligation comprising said spacer system and a delousing method of the herbarium using said spacer system. Hygiene is an important criterion in slaughterhouse work stations, such as cattle herding stations, in order, among other things, to prevent contamination of the meat.

There are several existing systems for improving hygiene during ruminant removal operations such as the ligation operation.

Ruminants, such as cattle, have a grasshopper, which looks like an esophagus and connects their throat to their belly, which carries the ingested and rusting forage through the animal when feeding and ruminating.

The ligation clips of the herbarium, such as those described in the French patent application FR2937504A1 aunom the applicant, allow to improve the ligature'herbière and thus avoid any pollution during evisceration, said clips for closing1 ' and thus prevent the contents of the animal's stomach from being spilled during the evisceration operation.

French patent applications FR2789266A1 and FR2927769A1, also in the name of the Applicant, describe a tool for assisting the disengagement of the moss and the laying of the ligation clip of the herbarium. When the meadow is cleared, the operator places the tool on the meadow with a hook provided for this purpose. The foam is then inserted into the tip of the device, then the operator presses the control button so that the rod of the tool so as to clear the foam from the collar to the animal's body. By releasing the control button, the tool shank retracts, then the operator grasps a deligature clip and places it on the lather just above the tip of the tool. By pressing the control button again, the tool shaft comes out again, turning the clip up to the belly. By releasing the control button again, the tool shaft retracts and the operation is complete. Thanks to the installation of the deligature clip, the herbarium is perfectly closed and waterproof. During evisceration, no liquid, such as jusvenant the rumen, is thus spread on the carcass of the animal or the operator or his workstation.

Also with the aim of improving the hygiene of the workstation of the ligation of the herbarium, it has also been developed a ruminant positioner which makes it possible to prevent the carcass of the animal from pivoting or swinging, but above all which spreads the front legs of the animal to allow the operator to work more easily and cleanly, without particularly touching the front legs of the animal. This ruminant positioner significantly reduces the pollution still existing during the operation of ligation of the herb, without, however, remove it completely. Indeed, the leather of a ruminant such as a bovine is a source of contamination and contains a large number of bacteria mainly provided by fecal materials.

With the existing ruminant positioner, the risk of contamination is greatly reduced by preventing the operator from touching the legs of the animal, the dirtiest part of the animal after the rectum. However, in order to prepare the meadow before ligation, it is necessary to make a vertical cut in the collar of the animal and to clear the trachea to gain access to the grass that is stuck to the back of it. This operation requires the operator to hold one hand in one hand and with the other hand to clear the trachea usually with a knife. To avoid any risk of cutting and improve the grip of the leather, the operator must then have a steel mesh, which increases the risk of decontamination. Once access to the trachea is achieved, it remains to detach the herbarium from it. For this reason, the operator must grasp the trachea with one hand and the other with the hand to separate them by tearing the tissues that connect them. This operation allows the transfer of contamination of the glove mesh of aciervers the herb and more generally to the trunk of the animal.

It is complicated to ask the operator to sift their hands after the trachea clearance operation, as the time for the herbicide ligation step in a slaughterhouse is limited. In addition, wearing a steel mesh glove makes it difficult to wash the hands of the operator.

In addition, when the operator uses the aforementioned clip removal tool, or a manual rod, the fact that the rod of said tool rises twice from the collar to the body of the animal allows to spread the contamination brought by the mesh glove of steel at the necklace during the separation of the herbarium, over the entire height of the meadow. It is therefore essential that the moss plant is not contaminated at any time by the slaughterhouse operator.

The present invention aims to solve the disadvantages of the prior art, by proposing a system of spacing the two edges of a cut formed in the dewlap of a ruminant slaughtered, which allows to further improve hygiene by avoiding what The operator does not have to touch the leather of the animal during the clearance of the meadow. Moreover, with this system of separation, the operator needs to wash his hands only at the end of the ligation operation, before treating the next animal.

The present invention also relates to a lettuce ligation post comprising said spreading system, and to a lettuce ligation method using said spacer system.

The subject of the present invention is therefore a system for spacing the two edges of a cutout formed in the dewlap of a ruminant slaughtered and suspended by at least one hindleg, said spacing system comprising a bearing structure carrying at least two clamps eachelelected to a resilient biasing means, each gripper being configured to clamp one of said two edges, the at least two grippers being arranged on the carrier structure to move said two edges away from each other as they pinch said two edges.

Thus, thanks to the grippers of the spacer system, the operator does not touch at any time the leather of the animal, which makes it possible to prevent the transfer of the contamination of the steel mesh glove worn by the operator towards the esophagus. This also keeps the operator's clothing as clean as possible, an operator with a dirty outfit can not do a clean job.

When the slaughtered ruminant is suspended by at least one hind leg, the operator can perform a vertical cut in the ruminant baleen and then fix the at least two clamps on both edges of the cutter, the return means of the clamps to separate the two sides of the ruminant cutting, without the operator having to touch the leather of the animal, in order to reach the duruminous herb to perform a ligation of the herbarium after installation of a ring on the latter.

The clamps hold each edge of the blank to the left and right of the blank, while spreading the blank as the trachea is released by the operator working in front of the blank.

The biasing means of the clamps also prevent the clamps at rest from hanging and negatively the operator or dirty.

According to a particular feature of the invention, the carrier structure is a gantry.

Preferably, the carrier structure is a ruminant positioner, such as the clip-on positioner sold by the Applicant, which is used to prevent the carcass of the animal from pivoting or swinging, said ruminant positioner being directly attached to a structure fixed or, to better adapt to the size of the ruminant, fixed to a fixed structure through at least one winding balancer.

According to a particular feature of the invention, the gantry comprises a device for separating the front legs of the ruminant.

Thus, the device for spacing front legs allows the operator to move the front legs of the animal end to freely access the collar of the animal and achieve a vertical cut in its dewlap, without the operator n ' needs to touch the front legs of the animal, which further ensures the hygiene of the operation of ligation of the herbarium.

According to a particular feature of the invention, the front leg spacer device comprises two uprights, on which are mounted at least two clamps, and a jack configured to separate said two uprights to separate the front legs hardening.

Thus, actuation of the jack by the operatorpermet to remove the front legs of the animal to achieve a cutting of dewlap without touching the front legs of the animal to ensure the hygiene of the operation deligature of the herb.

The clamps being mounted on the two uprights, they are thus close to the operator, which facilitates the gripping of the tongs operator once the latter has made the cut in the dewlap.

The lower ends of the two uprights preferably each have a hook configured to receive one of the front legs of the ruminant.

According to a particular characteristic of the invention, each elastic return means is at least one of an elastic whose end is connected to the supporting structure and the other end of which is connected to the corresponding clip, a winding balancer which carries a traction cable of which the end is connected to the corresponding lapse, a cylinder connected to one end of a traction cable whose other end is connected to the corresponding lapel and a winch connected to one end of a traction cable whose other end is connected to the corresponding clip.

Thus, in the case of a retractor balancer, it allows to maintain a more regular tensile force on the corresponding clamp an elastic whose stress is proportional to its elongation.

An example of a winding balancer is the TECNA® balancer sold by the Applicant.

According to a particular characteristic of the invention, the retractable balancers are positioned in the upper part of the two uprights of the front leg spacing device.

Thus, this prevents the balancersnrouleurs do not hinder the operator and do not clog.

According to a particular feature of the invention, the spacer system further comprises a traction cable guiding device or elastic for each elastic return means, said guiding device being preferably a hollow tube traversed by the tow cable or the elastic.

Thus, this makes it possible to avoid any blockage of the traction cable or of the elastic during its retraction in the rest position.

According to a particular feature of the invention, the inner surface of the jaws of each gripper is a textured surface, such as a peg surface or a fluted surface.

Thus, the textured internal surface of the clamp jaws allows better grip of the clamp on the animal's baleen leather.

According to a particular characteristic of the invention, each clamp has a tightening force greater than or equal to 1 N, preferably equal to 1 daN.

According to a particular feature of the invention, each clamp has a tensile force greater than or equal to 0.2 daN, preferably between 1 and 2 daN.

The present invention also relates to a slaughterhouse ligation station, comprising a spacer system as described above.

Thus, the hygiene of the lettuce ligation stationaccording to the present invention is improved compared to that of existing posts, using the spacer system that allows to separate the two edges of a dewlap cut without having to touch the leather the animal's dewlap, thus preventing contamination of the meat of the animal during the ligation operation.

The present invention furthermore relates to a method of ligation of a herbarium using a spacer system as described above, comprising the following steps: the cutting, by a slaughterhouse operator, of the dewlap unruminant shot and suspended by at least one pattearrière; the positioning, by the slaughterhouse operator, of the at least two clamps of the spacer system on the two edges of the cutout formed in the ruminant's baleen; - The spacing of the two edges of the cut by the elastic return means of the at least two clamps; - the positioning, by the slaughterhouse operator, of a ring on the ruminant's meadow; and the ligation of the ruminant's meadow by the slaughterhouse operator.

The ring disposed on the ruminant's meadow may for example be the lettuce ligation clip described in the French patent application FR2937504A1, said ring being able for example to be positioned on the meadow with the aid of the moss removal tool and Laying of the ligation ring of the herbarium described in French patent applications FR2789266A1 and FR2927769A1, all in the name of the Applicant.

To better illustrate the subject of the present invention, will be described below, by way of illustration and not limited to, a preferred embodiment, with reference to the accompanying drawings.

In these drawings: FIG. 1 is a perspective view of a spacer system according to the present invention; Figure 2a is a front view of the spacer system of Figure 1 when said gap system is not actuated; Figure 2b is a front view of the spacer system of Figure 1 when the front leg spacer is actuated; Figure 2c is a front view of the spacer system of Figure 1 when the operator of the slaughterhouse cuts into the durum bale; FIG. 2d is a front view of the spacer system of FIG. 1 when the operator of the slaughterhouse is positioning the two clamps of the spacer system on the two edges of the blank; and FIG. 2e is a front view of the spacer system of FIG. 1 when the two edges of the blank are spaced from each other by the tongs.

With reference to Figure 1, it can be seen that there is shown a spacer system 1 according to the present invention.

Said spacer system 1 is configured for spacing the two edges of a cutout formed in the flank of a ruminant slaughtered and suspended by at least one rearward leg.

The spacer system 1 comprises a carrier structure 2 carrying two clamps 3 each connected to an elastic return means 4.

It should be noted that the carrier structure 2 could also carry more than 2 clamps 3, without departing from the scope of the present invention. Thus, each cutting edge formed in the baleen could be separated by several clamps.

Each clamp 3 is configured to clamp one of two edges of the bale cutter, the two clamps 3 being arranged on the supporting structure 2 to separate said two edges away from each other when the two clamps 3 pinch said two edges.

The supporting structure 2 is a carrier comprising two uprights 2a whose upper ends are bent towards each other and are fixed to a fixing element 2b which is configured to be connected to a winding balancer (not shown in FIG. 1).

The lower ends of the two uprights 2a are also curved towards each other and each carries a hook 2c, configured to receive one of the two front legs of the suspended ruminant, and a grip 2d understanding comprising an actuating button 2e.

The carrier structure 2 also comprises a lever 5, as a ruminant leg spacer, the cylinder 5a and the piston 5b of which are respectively connected to the upper parts of the two uprights 2a of the support structure 2 by means of two plates 2f respectively fixed to the twomonths 2a, said cylinder 5 being configured to spread the two uprights 2a to separate the two hooks 2c and thus to separate the front legs of the ruminant placed in the hooks 2c. The operator can then make a vertical cut in the animal's dewlap, without having to touch the front legs of the animal, which can further ensure the hygiene of the operation deligature of the herb.

The deployment and retraction of the piston 5b duvérin 5 are controlled by the operator via deux deux buttons actonement arranged on the two grips 2d.

The particular configuration of the carrier structure 2 thus makes it possible to prevent the suspended carcass of the animal from pivoting or swinging in order to facilitate the work of the operator.

It should be noted that the spacer system 1 could also not include a ruminant front leg spacer without departing from the scope of the present invention.

The two clamps 3 and the associated elastic return means 4 are mounted on the two uprights 2a, so that the clamps 3 are located close to the operator, which facilitates gripping of the grippers 3 by the operator once the the latter realized the cut in the fanon.

Each elastic return means 4 is a retractable balancer 6 from which pulls a pull cable 7dont the end is connected to the corresponding clamp 3, which allows to maintain a regular traction force on the corresponding clamp 3.

It should be noted that the elastic return means 4 could also be at least one of an elastic member whose end is connected to the bearing structure 2 and whose other end is connected to the corresponding clamp 3, a jack connected to an end of a pulling cable whose other end is connected to the corresponding clamp 3 and a winch connected to one end of a tow cable whose other end is connected to the corresponding lapse 3, without departing from the scope of the present invention.

Retractor balancers 6 are positioned in the upper part of the two uprights 2a of the supporting structure2, towards the outside of the support structure 2, which makes it possible to prevent the retrofit balancers 6 from disturbing the operator and becoming dirty.

The spacer system 1 also comprises a hollow tube 8, as a traction cable guiding device, for each winding balancer 6, said tubecream 8 being traversed by the pulling cable 7 of the associated winding balancer 6, the associated clamp 3 being attached to the end of the pulling cable 7 exiting the lower end of the hollow tube 8, which avoids any locking traction cable 7 when pulling in the rest position. Each hollow tube 8 is attached to one of the two uprights 2a by means of two tightening elements 9.

The inner surface of the jaws of each gripper 3 is a textured surface, such as a pimpled surface or a fluted surface, which allows a better grip of the gripper 3 on the leather of the baleen of the animal.

Each clamp 3 has a tightening force greater than or equal to 1 N, preferably equal to 1 daN.

Each clamp 3 has a tensile force greater than or equal to 0.2 daN, preferably between 1 and 2 daN.

The present invention also relates to a slaughterhouse ligation station, comprising the spacer system 1 according to the present invention. Thus, the hygiene of the lettuce ligation station according to the invention is improved with the aid of the spacer system 1 which allows to separate the two edges of a baleen cutout without having to touch the leather of the fanon of the animal, which prevents contamination of the animal's meat during the lettuce ligation operation.

The present invention further relates to a method of lettuce ligation with the aid of the spacer system 1 according to the present invention, comprising the following steps: - the cutting, by a slaughterhouse operator, of the dewormer slaughtered and suspended by at least one pattearrière; the positioning, by the slaughterhouse operator, of the two clamps 3 of the spacer system 1 on the two edges of the cutout formed in the ruminant's baleen; - The spacing of the two edges of the cut by the elastic return means 4 of the two clamps 3; - the positioning, by the slaughterhouse operator, of a ring on the ruminant's meadow; and the ligation of the ruminant's meadow by the slaughterhouse operator.

Thus, thanks to the clamps 3 of the spacer system1, the operator does not touch at any time the animal's leather, which makes it possible to prevent the transfer of the contamination of the steel mesh glove worn by the operator towards the animal. 'esophagus.

Referring to Figure 2a, it can be seen that there is shown the spacing system 1 when the piston 5b of the cylinder 5 is in the retracted state.

A slaughtered ruminant 10, suspended by at least one hindleg on a rail, is positioned by the operator in the carrier structure 2 such that the two front legs 11 of the ruminant 10 are placed in the two hooks 2c of the spacer system 1.

Referring to Figure 2b, it can be seen that there is shown the spacing system 1 when the piston 5b of the cylinder 5 is in the deployed state. The operator grasps the two forearm handles 2d disposed on the lower ends of the two uprights 2a, then actuates the actuating buttons 2e to deploy the piston 5b of the cylinder 5, so as to distance the two front legs 11 of the ruminant 10 and access the baleen of the ruminant 10.

Referring to Figure 2c, it can be seen that there is shown the cutting, by the slaughterhouse operator, of the ruminant 10 fanon. The operator makes a vertical cut 12 in the ruminant fan 10 to 10 using a knife 13, the vertical cutout 12 having two opposite edges 12a.

Referring to Figure 2d, it can be seen that there is shown the positioning, by the slaughter operator, of the two clamps 3 of the spacer system 1 on the two edges 12a of the vertical cutout 12 formed in the 10 The operator grasps each clamp 3 in order to pinch one of the two edges 12a of the vertical cutout 12, the reels balancers 6 allowing the unwinding of the traction cables 7 so that the clamps 3 can reach said two edges 12a.

With reference to FIG. 2e, it can be seen that there is shown the spacing of the two edges 12a of the vertical cutout 12 by the elastic return means 4 of the two clamps 3.

The retractor balancers 6 exert a tensile force on the traction cables 7, which allows the spacing of the two edges 12a away from each other.

The clamps 3 thus make it possible to hold each edge 12a of the fanon to the left and to the right of the blank 12, while spreading the blank 12 as the trachea is released by the operator with the aid of the knife 13.

The biasing means 4 of the clamps 3 also prevent the clamps 3 at rest from hanging and annoy the operator or dirty. The operator then positions a ring (not shown in FIG. 2e) on the ruminant's meadow 10, then performs a ligation of the ruminant's meadow 10 with the aid of the knife 13.

The ring disposed on the ruminant's meadow 10 may, for example, be the lettuce ligature clip described in the French patent application FR2937504A1 in the name of the Applicant, said ring being able, for example, to be positioned on the meadow with the aid of the tool. Herbaceous dressing and laying of a herbaceous ligament ring described in the French patent applications FR2789266A1 and FR2927769A1, in the name of the Applicant.
