Description

[Detailed Description of the Invention] The present invention relates to a device for separating the head and neck of a bird carcass, and more specifically, to a device for efficiently and automatically separating the class A skin of the head and neck.

Conventional methods for cutting off the head and neck of a bird carcass include manually tearing off the head using a knife, and mechanically tearing off the head. When cutting the carcass, the bone at the rear of the single artery incision during slaughtering is broken by hand and then separated using a knife, which is very tiring and dangerous, and the labor cost is high due to the simple work. The drawback was that it was expensive. or,
In the latter case, there was a disadvantage that a large amount of class A neck skin was attached to the head side, resulting in a large loss of class A neck skin.

This invention is proposed in view of these points,
The object of the present invention is to obtain a cutting device which can cut off the head and neck of a bird carcass by mechanical force and which can reduce the loss of class A neck skin as much as possible.

The structure of the present invention will be described in detail below. First, the main feature of the structure is that it is arranged below the hanging line of the bird carcass, along the traveling direction, and creates a gap for the head and neck of the bird carcass to pass through. Two guides placed in the
Below this guide, a screw is arranged along the gap between the guides and is configured to be rotated by a motor; above the guide, a screw is arranged along the gap between the guides and rotates in the traveling direction. Two spiral rollers whose spacing gradually narrows as they move toward each other, and the roller is arranged between the terminal end of the spiral roller and the guide so that its blade protrudes throughout the gap between the guides, and is driven by a motor. After blood removal, the bird carcass suspended upside down on the hanging line approaches the device of the present invention, and the head of the bird carcass is placed in the screw, and the head and neck are placed in the gap between the guides and It goes between two spiral rollers. The head is a screw, and the head and neck are fed between the spiral rollers, and the head and neck sandwiched between the spiral rollers are rotated upward as the distance between the spiral rollers gradually narrows. Gradually slide the neck skin upwards.
If a knife hits the head and neck of someone sent in this condition,
The neck skin of the head and neck area is efficiently cut off without remaining on the head side.

The attached drawings show an embodiment of the present invention, in which 1 is a device body disposed along the traveling direction of a bird carcass hanging line (chain) (not shown);
Reference numerals 2 and 2' are below the hanging line, and are arranged along the advancing direction, and are arranged on the main body 1 of the apparatus with a gap 3 through which the head and neck of the bird carcass pass.
A screw 6, which is disposed below the guides 2, 2' along the gap 3 of the guides 2, 2', and whose rotation is transmitted via a transmission part 5 by a motor drive; 6' forms a spiral on the surface, and is disposed on the guides 2, 2' along the gap 3 of the guides 2, 2', and the gap gradually narrows in the direction of travel, and the screw 4 Two spiral rollers whose spiral pitch is regulated to be the same as the rotational feed of the screw 4 are rotated by the same drive system as the screw 4.

7 is the guide 2, 2' and the spiral roller 6,
This cutter 7 is fixed to a rotating shaft 8, and its cutting edge protrudes into the entire gap 3. Note that although the cutter 7 in the embodiment has a circular shape, it does not necessarily have to be circular. In the figure, 9 and 9' indicate bearings for the spiral rollers 6 and 6', and 10 and 10' indicate fixing screws for the guides 2 and 2'.

The embodiment has the above-mentioned structure, and its operation will be explained next.The blood-removed bird carcass is hung upside down on a hanging line and sent. and,
When it reaches this device, its head engages the screw 4, and its head and neck enter the gap 3 between the guides 2 and 2.
sent gradually. Then, as shown in Fig. 4, the scalp of the head and neck is slid upward by the rotation of the spiral rollers 6 and 6', and at this point, the tip of the knife 7 touches the head and the head is cut off. It will be done.

As described above, in the present invention, the head is cut off after the neck skin is rolled up using a spiral roller, so that even the A-class neck skin shown by diagonal lines in FIG. 5 can be efficiently collected.

In addition, in the device of the present invention, all of the steps leading to the collection are performed mechanically, so that it is efficient and reduces labor costs.
