SYSTEM FOR HANGING POULTRY

Abstract

A system for hanging poultry by the legs and feet in a shackle of a conveyor line. A supply line with at least one first carrier for the poultry. A movable take over device can receive the legs of the poultry and transfers the poultry from the at least one first carrier to the shackle in the conveyor line at a transfer location. The shackle, the movable take over device, and the at least one first carrier can be aligned. The movable take over device can be arranged to engage the legs of the poultry at the transfer location, move the feet above the shackle, move the feet downwards into the shackle, and disengage the legs. Pushing equipment pushes the poultry from the at least one first carrier to the movable take over device when the poultry is at the transfer location.

DETAILED DESCRIPTION OF THE INVENTION

[0022] For purposes of describing the invention, reference now will be made in detail to embodiments and/or methods of the invention, one or more examples of which are illustrated in or with the drawings. Each example is provided by way of explanation of the invention, not limitation of the invention. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope or spirit of the invention. For instance, features or steps illustrated or described as part of one embodiment, can be used with another embodiment or steps to yield a still further embodiments or methods. Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents.

[0023] FIGS. 1, 2, 3, and 4 show (parts of) an exemplary system 1 for hanging poultry 2 by the legs 3 and feet 3 in a shackle 4 of a conveyor line 5.

[0024] FIGS. 1 and 2 show that the system 1 includes a supply line 6 with at least one first carrier 7 for the poultry 2, a movable take over device 8 for receiving the legs 3 of the poultry 2 and for transfer of the poultry 2 from the at least one first carrier 7 of the supply line 6 to the shackle 4 in the conveyor line 5. As shown in the figures and within the scope of the present subject matter the first carrier 7 for the poultry 2 carries the poultry preferably suspended by the hocks.

[0025] Transfer of the poultry from the at least one first carrier 7 of the supply line 6 to the shackle 4 in the conveyor line 5 occurs at a transfer location wherein the movable take over device 8, and the at least one first carrier 7 of the supply line 6 may be aligned as shown in FIG. 2. As depicted in FIGS. 1, 2, 3, and 4, the movable take over device 8 may be separate from the supply line 6 and mounted on a carrousel along which the conveyor line 5 with the receiving shackle 4 may be guided.

[0026] The movable take over device 8 may be arranged to engage the legs 3 of the poultry 2 at the transfer location so as to move the feet 3 first to a position above the shackle 4 as shown in FIG. 3, and then move the legs 3 subsequently downwards and towards the shackle 4 as depicted in FIG. 4. Once the feet 3 and legs 3 are brought in position with reference to the shackle 4 as shown in FIG. 4, the movable take over device 8 disengages the poultry legs 3 so that the poultry may be entirely suspended by the feet 3 from the shackle 4. This may be depicted in FIG. 4.

[0027] To support the transfer of the poultry 2 from the at least one first carrier 7 of the supply line 6 to the shackle 4 in the conveyor line 5, the motion of the legs 3 and feet 3 may be predominantly defined by the movable take over device 8. In connection therewith the system 1 may further include pushing equipment 9 for pushing the poultry from the at least one first carrier 7 of the supply line 6 to the movable take over device 8 when the poultry 2 may be at the transfer location shown in FIG. 2. In an exemplary aspect, preferably this pushing equipment 9 may include a push bar.

[0028] To secure the handling of the legs 3 and the feet 3 of the poultry 2 by the movable take over device 8, the device 8 may include a locking element or elements 10 to trap the poultry legs 3 after they are received in closable slits 14 of the movable transfer device 8. This may be shown in FIG. 5. This feature may be particularly helpful when after the movable transfer unit 8 has first moved the feet 3 above the shackle 4 as shown in FIG. 3, the legs 3 of the poultry 2 are subsequently moved downwards, towards and into the shackle 4 as depicted in FIG. 4, such that during this movement the fingers of the feet are pushed against the top side of the shackle 4.

[0029] When the legs 3 are in the shackle 4 as depicted in FIG. 4, the locking element or elements 10 may be arranged to release the poultry legs 3.

[0030] Turning now to FIG. 6, another exemplary aspect of the present subject may be highlighted, wherein the system may include an infeed conveyor (not shown) and at least one robot 11 for picking up the poultry 2 from the infeed conveyor. The robot 11 may be arranged to first suspend the poultry 2 by the head 12 as shown in FIGS. 6 and 7. After that in a series of operations the poultry 2 may be eventually suspended by the legs 3 in the at least one first carrier 7 of the supply line 6.

[0031] In a first step of the series of operations the at least one robot 11 may be equipped for initially keeping the poultry 2 suspended by the head 12 while moving the poultry legs 3 into the at least one first carrier 7 of the supply line 6, with the poultry being heads-up. This operation may be completed in FIG. 7.

[0032] FIG. 8 depicts that a part 7 of the at least one first carrier 7 that engages the legs 3 of the poultry 2 may be rotatable around a horizontal axis to enable flipping of the poultry 2 from its position suspended by the head 12 to a position suspended by the legs 3, as shown in FIG. 9.

[0033] It shows in FIG. 9 that the back 2 of the poultry 2 faces the at least one first carrier 7 of the supply line 6 when the poultry 2 may be suspended by the legs 3.

[0034] FIG. 6 and FIG. 7 show that the at least one robot 11 has engagement flaps 13 made of a resilient material such as rubber or polymer to reduce relative movement of the poultry 2 with respect to the robot 11 as the poultry 2 may be being picked up and moved by the robot 11.

[0035] Although the invention has been discussed in the foregoing with reference to an exemplary embodiment of the invention, the invention is not restricted to this particular embodiment which can be varied in many ways without departing from the invention. The discussed exemplary embodiment shall therefore not be used to construe the appended claims strictly in accordance therewith. On the contrary the embodiment is merely intended to explain the wording of the appended claims without intent to limit the claim to this exemplary embodiment. The scope of protection of the invention shall therefore be construed in accordance with the appended claims only, wherein a possible ambiguity in the wording of the claims shall be resolved using this exemplary embodiment.

[0036] Variations and modifications of the present invention will be obvious to those skilled in the art and it is intended to cover in the appended claims all such modifications and equivalents. The entire disclosures of all references, applications, patents, and publications cited above are hereby incorporated by reference. Unless specifically stated as being essential above, none of the various components or the interrelationship thereof are essential to the operation of the invention. Rather, desirable results can be achieved by substituting various components and/or reconfiguration of their relationships with one another.
