Abstract

Breaking tool in the form of a hammer head fitted on the free end of a shaft which pivots at its lower end on a horizontal axis, and has a knife-like pane projecting forwards, is provided in an arrangement for removing the neck of a plucked, headless fowl hanging from a conveyor. Beneath the forked clamping detail which receives the neck of the fowl, and moves with the conveyor, lifting and lowering relatively to it, an auxiliary fork is fitted. In its active posn., the knife-like pane is located between the clamping fork and the auxiliary fork. The clamping fork projects from a carriage sliding on vertical guides forming part of a frame moving with the conveyor. The carriage and the breaking tool are provided with cam followers which engage with cam tracks and control the mutually synchronised motions of the tools. The hammer head makes a quick and complete break through the neck vertebrae of the fowl and the knife edge separates them completely. Thus as the carriage descends, the neck bones are pressed out correctly The neck tissue is not damaged and is definitely not cut.

Device for removing the neck of a plucked, headless bird

The present invention relates to a device for removing the neck of a plucked, headless bird suspended from a conveyor, comprising at least one moving with the conveyor and thereby also with respect to the conveyor qp and down moving, fork-shaped clamping member, which can receive the neck of the bird and which is mounted transversely on an associated carriage, which carriage is slidable along a vertical guide of a frame part moving with the conveyor, and one with respect to the movement of the clamping member breaking member moving from the fork opening thereof, which is hingedly connected to the slide and where the slide and the breaking member are provided with followers cooperating with fixed cam tracks, which cam guides control the vertical movement of the carriage and the pivoting movement of the breaking member in synchronized manner with one another that the breaker in a high carriage tooth to the bree position and is pivoted to neutral in a low slide position.

A similar device is known from the published Dutch patent application 150,689. In this known device, the breaking member forms one arm of a V-shaped lever, the other arm of which is the follower, which can cooperate with the fixed cam track. The lever is pivotable about a vertical axis at the tip of the V-shaped lifting beam, the breaker pivoting in a horizontal plane thereby pushing the bird's neck into the fork-shaped clamping member, thereby breaking the bird's neck. With the continuing movement of the fork-shaped clamping member along with the conveyor, the carriage is moved downwards by means of the follower in the curve path along the guide, whereby the neck vertebrae with adhering flesh through the opening formed by the removal of the head squeezed out of the neck skin. With this known in- 7904779i? In the 2 direction, the breaking member on the side facing the neck of the bird is provided with a plane which is vertically flat, which is concave curved in a horizontal plane.

The device according to the invention differs from the known device in that the breaking member is in the form of a hammer, which is hinged at the free end of its stem at the bottom about a horizontal axis on the slide, in that it hammer-shaped breaking member is provided with an active part in the form of a knife-shaped head and in that an auxiliary fork is mounted under the fork-shaped clamping member 10, such that the knife-shaped head of the breaking member is in the active position between the fork-shaped clamping member and the auxiliary fork located.

By applying these measures it is achieved that the breaking member strikes, as it were, with a hammer blow on the neck of the bird, whereby a sudden and rapid, complete expansion occurs in the cervical vertebrae. The knife-shaped head creates a separation between the cervical vertebrae, so that the cervical vertebrae can be squeezed out easily and flawlessly during the downward movement of the carriage.

In a preferred embodiment of the device according to the invention, the knife-shaped head tapers towards the rounded free knife edge.

Thus, in spite of the blow delivered to the bird's neck with the hammer-shaped breaker, the neck skin of the bird is prevented from being damaged, let alone cut.

In a particularly efficient embodiment of the device according to the invention, a rotatable roller is mounted on the handle of the hammer-shaped breaking member, which co-acts with one of the fixed curved tracks,

The invention will be explained in more detail with reference to the drawing with an exemplary embodiment.

The device according to the drawing for removing the neck of poultry is carousel-shaped and comprises a frame 1 with a vertical fixed shaft 2, on which two round supporting plates 5 and 6 are rotatably mounted with ball bearings 3 and k. A number of vertical guide rods 7 are mounted between the plates 5 and 6, which are arranged parallel to each other and in pairs regularly distributed over the circumference of the plates 5 and 6. A breaking unit 8 is vertically slidably mounted on a pair of guide rods 7. Each breaking unit 8 is provided with a slide 9, which is slidable on the rods 7 by means of bearing bushes 10, with a radially outwardly projecting fork-like clamping member 11 and with a hammer-shaped breaking member 12 cooperating therewith.

The fork-shaped clamping member 11, which is clearly shown in Figures 2 and 3, consists of the actual fork 12 and of an auxiliary fork 13, both of which are welded, soldered or otherwise attached to the carriage 9.

The carriage 9 is provided on the inside (see fig. 1) with a follow roller ifc, which runs in a curved track 15, which is arranged in the form of two strips on a drum-shaped support 16, the support 16 fixed on the stationary shaft 2 is attached. The course of the curve track 15 is shown in the deflection of the drum-shaped carrier in Fig. 6. When the roller 1 ^ is in the lower part 1 of the cam track 15, the breaking unit 8 is in its free lowest position and when the roller ih is in the highest part 15 "of the cam track 15, the breaking unit 8 is in its highest, active position.

The hammer-shaped breaking member 12 is hingedly mounted by means of a horizontal axis 17 on a bracket 18, which is welded to the carriage 9. The hammer-shaped breaking member 12 consists of a shank 19 and a head 20, in which the shank 19 has a rotatable nylon roller 21 and the head 20 is knife-shaped, which tapers towards the rounded free knife edge 22.

The roller 21 on the hammer-shaped breaking member 12 runs during the rotary movement of the device 3-8 about the shaft 2 over a curve path 23, which is supported on the fixed shaft 2 by means of L-shaped brackets 2k pp. The cam track consists of a round rod 23 and has a side view, that is to say in a vertical sense, essentially the same course as the cam track 15, except for a run-in 23 and a run-out 26. The run-in 23 runs in the direction of rotation of the crushing units 8 steeply upwards and inward in the radial direction. The run-out 26 runs in the direction of rotation of the breaking units 8 in the opposite direction with respect to the run-in 23.

The stem 19 of the hammer-shaped breaker 12 is on the side opposite the hinge axis 1? provided with an extension piece 27 (fig.

2), that at the beginning of the run-out 26 (the arrow in Fig. 5 indicates the direction of rotation) comes into contact with a stop rail (not shown), which pushes the extension 27 in a radially inward direction, thereby breaking the hammer-shaped breaking member 12 from the operative position, drawn in solid lines in FIG. 2, to the free position, which is drawn in dashed-dotted lines in FIG. 2, the nylon roll 21 following the run-out 26.

A drum 28 is adjustable in height direction on the upper support plate 3 of the device (see fig. 4). On the drum 28 vertical upright brackets 29 are mounted vertically above the crushing units 8, which project into the drum with the ends of the legs .

Furthermore, a sleeve 30 is mounted on the top support plate 5 concentrically with respect to the shaft 2, which at its top end is provided with an L-shaped bracket 31, which engages in an opening of a drive wheel 32, which is rotatable on the top part of the shaft 2 is supported. The drive Fell 32 is provided on the periphery with drive chain drive members 33 (FIG. 7), on which are spaced 7904779 * 5, corresponding to the arc distance between the breaker units 8, carriages 34, which are wheels run on a rail 35. Double U-shaped hooks 37 in which the birds are suspended with the ankle joints are suspended from the wagons with the aid of eye brackets 36.

The device according to the invention is vertically mounted in the frame 1 by means of a rack-and-pinion gear 39 (see Fig. 1), the shaft 2 at the bottom end of which is provided with a gear rack 40, which with the gearbox 39, which is drivable with a crank 41 and a shaft 42, is adjustable in height direction, the entire device moving with the shaft 2. This adjustment option serves to adapt the device to different types of poultry.

The frame 1 is supported on the floor by three legs, a single leg 43, which is an extension of one of the vertical bars of the rectangular frame 1, and a double leg 44, 45, which underneath the horizontal bottom beam of the frame 1 which is also used for mounting the gear rack 39.

The operation of the above-described device is as follows:

The birds, the neck of which must be broken and removed, are each hung with the ankle joints in the double U-shaped hooks 20 37 and are fed to the device at a time by the chain conveyor 33. The birds are guided on the outside by one or more guides 38, which saw that the bird assumes the correct position relative to the device, the legs of the bird being situated on either side of the U-shaped brackets 29 the drum 25 28 and that the neck of the bird is received in the fork form clamping members 12 and 13 of one of the breaking units 8. As the breaking unit 8 continues to rotate, the follower roller 21 of the hammer-like breaking member 12 comes into contact with the run-in piece 25 of the cam track 23 and at the same time the carriage 9 with the roller 14 in the cam track 15 moves upwards along the guide rods 7. When the carriage 9 arrives at its highest point (to the left of the shaft 2 in fig. 1), the run-in piece 25 of the cam track 23 reaches its innermost point and the hammer-shaped breaking member 12 with the knife-like head 22 is placed between the two fork-shaped members 12 and 13 are knocked off the clamping member 11, thereby separating the bird's cervical vertebrae from each other. Then the carriage 9 is passed through the cam track 15 7904779
