Deboner for Poultry Parts

Abstract

A deboner for a poultry part equipped with a first jaw and a second jaw mounted on an up-and-down movable slide block supporting a first frame portion, a second frame portion, and a third frame portion. The first jaw and the second jaw are movable towards and away from each other, wherein the first jaw is through a first hinge connected with the first frame portion so as to enable a rotational movement of the first jaw with respect to the first frame portion. A second hinge pivotably connecting the first frame portion to the third frame portion and a third hinge pivotably connecting the second frame portion with the third frame portion share a common axis of rotation.

Description

[0015] In the drawing:

[0016] FIGS. 1-3 show a single deboner according to the invention in a side view in three subsequent stages;

[0017] FIG. 4 provides a detailed view at the first jaw;

[0018] FIG. 5 provides a detailed view at the second jaw; and

[0019] FIG. 6 provides an isometric view at the deboner.

[0020] Whenever in the figures the same reference numerals are applied, these numerals refer to the same parts.

[0021] In FIGS. 1-3 a deboner 1 for a poultry part 2 is shown, wherein the poultry part 2 is suspended in a conveyor that has a series of carriers. The FIGS. 1-3 show for clarity only a single carrier 3 and a single poultry part 2 suspended therefrom. The conveyor with the carrier(s) 3 move poultry part(s) along the deboner 1 so as to enable processing of the poultry part(s) 2 by the deboner 1.

[0022] The deboner 1 is equipped with a first jaw 4 and a second jaw 5 that are (eventually) mounted on a slide block 6. The slide block supports a first frame portion 8, a second frame portion 12 and a third frame portion 16, as will be discussed further hereinafter. The jaws 4, 5 are movable towards and away from each other between a nonoperative position (FIG. 1) and an operative position (FIG. 3) in which the jaws 4, 5 engage the poultry part 2 that is being processed. FIG. 2 represents an intermediate position between the nonoperative position of FIG. 1 and the operative position of FIG. 3.

[0023] FIGS. 1-3 show that the first frame portion 8 is rotatably mounted through a second hinge 15 on the third frame portion 16. Like the first frame portion 8 and the second frame portion 12, the third frame portion 16 is supported by slide block 6 which is up-and-down movable. The jaws 4, 5 are thus arranged to be jointly movable up and down for assuming an initial altitude which is shown in FIG. 3. After this initial altitude as shown in FIG. 3 has been assumed, the jaws 4, 5 can be moved down for processing, that is stripping the meat from the poultry part starting at said initial altitude. This is all clear for the skilled person and requires no further elucidation.

[0024] In FIGS. 4-6 specific features are shown that contribute to the effectiveness and high yield of the deboner 1 of the invention.

[0025] In FIG. 4 it is shown that the first jaw 4 is through a first hinge 7 eventually supported by the first frame portion 8 so as to enable a rotational movement of the first jaw 4 with respect to the first frame portion 8. Accordingly the first jaw 4 can adjust to a dimension of the poultry part to be processed. This includes adjustment to any knuckle present in the poultry part. The first jaw 4 is preferably spring-loaded with a spring 9 that engages a lever arm 10 of the first jaw 4 so as to urge the first jaw 4 in use towards the poultry part.

[0026] FIG. 5 shows that also the second jaw 5 is connected through a fourth hinge 11 with the second frame portion 12 so as to enable a rotational movement of not only the first jaw 4, but also the second jaw 5, the latter with respect to the second frame portion 12. In this manner both the first jaw 4 and the second jaw 5 can adjust to the dimension of the poultry part or to the knuckles present therein. FIG. 5 further shows the preferable feature that also the second jaw 5 is spring-loaded with a spring 13 engaging a lever arm 14 of the second jaw 5, so as to urge the second jaw 5 in use towards the poultry part to be processed.

[0027] FIG. 6 further shows that the first frame portion 8 is connected to a first actuator 17 for executing a rotational movement of the first frame portion 8 with respect to the third frame portion 16. Likewise the second frame portion 12 is rotatably mounted through a third hinge 19 with the third frame portion 16, wherein further the second frame portion 12 is connected to a second actuator 18 for executing a rotational movement of the second frame portion 12 with respect to the third frame portion 16.

[0028] To support the operation of plural deboners of the invention in combination with a carousel type device, it is further shown that in each deboner, the slide block 6 is provided with a first guide wheel 21 and the first actuator 17 and the second actuator 18 are connected to another slide block 20 provided with a second guide wheel 21, wherein both guide wheels 21, 22 are equipped to cooperate with guide tracks (not shown but extensively known to the skilled person) provided at a carousel-drum's circumference such that the slide blocks' 6, 20 altitude is determined by the guide tracks of the drum.

[0029] Finally it is shown that the second hinge 15 of the first frame portion 8 and the third hinge 19 of the second frame portion 12 share a common axis of rotation.

[0030] Although the invention has been discussed in the foregoing with reference to an exemplary embodiment of the deboner 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 claims 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.
