Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an automatic chicken killing device that automatically and continuously cuts the necks of chickens in order to provide the chickens for human consumption.

(Prior art) Conventionally, chickens are hung upside down and conveyed one after another by being equipped with a hanging conveyor that hangs chickens upside down and a neck transfer conveyor that clamps the neck and aligns it with rotating blades. A device has been developed that uses a rotating blade to cut the neck.

(Problems to be Solved by the Invention) In general, when killing chickens, it is preferable to cut only the artery on the cervical side without cutting off the head of the chicken, in order to obtain high-quality chicken meat.

However, with conventional automatic chicken killing machines, the direction of the neck is not constant when cutting with the rotary blade, so when cutting only the carotid artery, the operator must hold the neck and align it with the rotary blade each time it is cut. If this is not the case, deep cuts have to be made to ensure the animal is killed, and in some cases the neck is cut off, or even the jugular bone is cut off. There was a problem that the quality of the inside of the chicken deteriorated.

In view of these conventional problems, the present invention aims to provide an automatic poultry killing device that can automatically and accurately cut only the carotid artery portion without operator assistance.

(Means for Solving the Problems) In order to solve the above-mentioned problems and achieve the intended purpose, the present invention proposes a hanging conveyor that transports chickens in a line by locking their legs and suspending them upside down. a neck transfer conveyor that is disposed below the hanging conveyor and substantially parallel to the hanging conveyor and moves while holding the neck of the chicken suspended on the hanging conveyor; a rotary blade for cutting the neck of the neck, the neck transport conveyor includes a rail portion for sliding the neck along the upper edge, and an endless chain that moves parallel to the rail portion at a constant distance; The endless chain is provided with a large number of neck holding claws that protrude toward the rail part and have chevron-shaped tips, and the chicken is held at the rotary blade position between the rail part and the neck holding claws. The automatic poultry killing device was equipped with a head push-up guide for pushing up the head of the chicken.

(Function) This automatic chicken killing device draws both legs of chickens in a predetermined direction on a hanging conveyor and transports them one after another. At this time, the live chicken is hung upside down and its head is lifted. In this state, the neck that the chicken has lifted by itself is inserted between the adjacent claws of the neck transport conveyor and between the upper edge of the rail and transported. Then, the head rests on the push-up guide at a position near the rotary blade. At this time, the head is pushed up and slid on the upper surface of the guide, so the neck is forcibly turned sideways and sent to the rotating blade position, where only the carotid artery is cut.

(Example) Next, an example of implementation of the present invention will be described in detail with reference to the drawings.

In the figure, 1 is a hanging conveyor. This hanging conveyor 1 has an endless chain 3 that rotates along a guide rail 2, and hanging tools 4, 4, . . . are supported on the endless chain 3 at regular intervals. Each hanging tool 4 has a pair of leg clamping parts 4a, 4a at the lower end.
It has an integrated mechanism that allows both legs of the chicken to be locked.

A spiral conveyor 5 for feeding is provided below the hanging conveyor 1 and parallel to it. This spiral conveyor 5 has a pair of rotating tubes 6 at different heights,
6, and spiral protrusions 7, 7 are integrally provided on the outer periphery of each rotary cylinder 6, 6, and both rotary cylinders 6, 6
By rotating the , as shown in FIG. 5, the breast of chicken A suspended on the above-mentioned hanging conveyor 1 is moved at the same speed as the hanging conveyor 1 while being placed on the rotating cylinders 6, 6. I'm trying to make it happen.

A neck transfer conveyor 8 is provided below the hanging conveyor 1 and at an extended position of the spiral conveyor 5 to fit and transfer the necks of the chickens A while being suspended from the hanging conveyor 1. This neck transfer conveyor 8 is provided at a position slightly shifted from directly below the hanging conveyor 1, and has a rail part 9 on its upper edge that is slidable along the neck of the chicken A. An endless chain 10 is stretched above and parallel to the rail portion 9. This endless chain 1
0 is a pair of sprockets 1 with a horizontal axis
1 and 11, with the lower straight portion facing the rail portion 9. This endless chain 10
As shown in Figures 7 to 9, the bracket 1 is
A large number of cervical holding claws 13, 1 via 2, 12...
3... are attached close to each other.
Each neck holding claw 13 has a chevron-shaped tip,
The chevron-shaped inclined edges 13a, 13a and the rail portion 9
The neck of the chicken A is fitted into a space 14 surrounded by the upper edge of the chicken A, and the chicken A is transported at a slightly slower speed than the hanging conveyor 1 by rotating the endless chain 10.

A rotary blade 15 is provided at a position slightly in front of the terminal end of the neck transfer conveyor 8. This rotary blade 15 is located at an intermediate position between the suspension conveyor 1 and the neck transfer conveyor 8, is disposed close to and parallel to the rail section 9, and has an upper edge protruding higher than the upper edge of the rail section 9. The neck of a chicken A being conveyed on a rail section 9 is cut off.

Further, a head push-up guide 16 is provided on the opposite side of the rotary blade 15 with the rail portion 9 in between. This head pressing guide 16 is arranged parallel to the rail portion 9 from a position slightly before the rotary blade 15 in the feeding direction to a position past the rotary blade 15 position, and the top edge of the rail portion 9 is disposed at the tip end. It has a sloped part 16a with a lower height, and a horizontal part 16b that is continuous with the upper end of the sloped part 16a and is higher than the upper edge of the rail part 9.
, and a horizontal portion is located at the rotary blade 15 position.

The automatic chicken killing device configured as described above hangs the chicken A by holding both legs between the leg holding parts 4a, 4a of the hanging conveyor 1 with the back of the chicken A facing the neck transfer conveyor 8 side. When the breast is placed on the rotary cylinder 6 of the spiral conveyor 5 in this state, the chicken A is sent onto the spiral conveyor 5 to the starting end of the neck transfer conveyor 8 with its head slightly lifted. In the neck transport conveyor 8, the neck is fitted into a space surrounded by the rail part 9 and the inclined edges 13a, 13a of the neck holding claws 13, 13 adjacent to each other, and is transported on the rail part 9. When the head of chicken A reaches the head pushing up guide 16, the head of chicken A is pushed up by the inclined part, and the beak part is rubbed on the head pushing up guide 16 as it is transferred, as shown in FIG. The head is forcibly turned sideways, and the carotid artery at the side of the neck is directed downward and transferred to the rotary blade 15 position where it is cut. Note that, since the speed of the neck transfer conveyor 8 is slower than the conveyance speed of the hanging conveyor 1, the gap between the neck holding claws 13 and 13 gradually increases from the start of transfer by the neck transfer conveyor 8 to the cutting by the rotary blade 15. The neck is held and pulled,
It is cut in a state where it is stretched and has fewer degrees of freedom.

In the embodiments described above, a spiral conveyor is used to feed the chicken necks to the neck transfer conveyor, but this is not necessary and the chicken necks may be fed to the neck transfer conveyor manually or by other means. a.

(Effects of the invention) The automatic chicken killing device of the present invention is configured as described above, and includes a rail part for sliding the neck part along the upper edge of the neck transfer conveyor, and a rail part for sliding the neck part along the upper edge of the conveyor, and a rail part for sliding the neck part along the upper edge of the conveyor. an endless chain that moves parallel to the rail, and an endless chain that protrudes toward the rail portion,
The chicken head is constructed with a large number of neck holding claws each having a chevron-shaped tip, and is held between the rail portion and the neck holding claws at a rotary blade position for cutting the neck held by the conveyor. By installing a head-pushing guide to push up the neck, the lower side of the neck of a chicken hung upside down is cut sideways, and only the carotid artery can be cut automatically and accurately without the need for assistance. This means that it can be cut.
