Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric stimulator for carcasses of pigs, cattle, sheep and the like, and more particularly to a carcass disposed between an anesthesia device and a visceral extraction work bay of a slaughter processing line. The present invention relates to an electric stimulator.

[0002]

2. Description of the Related Art Conventionally, as an example of this type, there is an electric stimulator for a carcass described in Japanese Utility Model Publication No. 4-171014.

However, this carcass electrical stimulator is

A trolley member to be conveyed, an electrode plate provided on a floor through which the trolley member passes, a low voltage pulse when the carcass is in sliding contact with the electrode plate and the elevated rail. And a low-voltage pulse generator that flows into the body of the carcass.

However, in the carcass electrical stimulator having the above structure, since the electrode plate is provided on the floor surface, it is necessary to perform installation work on the floor surface which is waterproofed. In addition, there is a problem in that it not only hinders the work of the worker, but also that cleaning cannot be easily performed after the work.

Further, since the electrode plate provided on the floor is provided horizontally, the carcass has a predetermined size (standard).
When the size is smaller than that, there is a drawback that the nose does not sufficiently slide on the electrode plate.

[0006]

In view of the above conventional drawbacks, it is not necessary to perform installation work on the floor surface, and it does not hinder the work of the worker and facilitates cleaning after work. Another object is to obtain an electric stimulator for a carcass that can sufficiently slide its nose on the electrode plate even when the carcass is smaller or larger than a predetermined size (standard).

[0007]

An electric stimulator for a carcass of the present invention comprises an elevated rail 1 arranged between an anesthesia apparatus 2 and a visceral extraction work bay 4 of a slaughter processing line, and the elevated rail. A trolley member 6 for transporting a carcass 5 suspended by the anesthesia device and anesthetized by the anesthesia device through a suspending tool 7 along an elevated rail.
And a support arm 30 fixedly suspended on the elevated rail 1 of the work bay X in the section through which the trolley member passes.
And a bar-shaped electrode body 9 fixed to the support arm and spaced from the floor F, and connected to the electrode body and the elevated rail via a plurality of electric wires, respectively, into the body of the carcass. Low-voltage pulse generator 12 for applying electric pulse
It consists of and.

[0008]

First, when the trolley member guided by the inclined rail moves up, the carcass is in a state of being suspended by a suspender as shown in FIG. Then, the carcass suspended by the suspenders
It is transported to the work bay while being pushed by the push plate of the trolley member.

Next, when the carcass is transported to the work bay X, the nose of the carcass slides on the bar-shaped or plate-shaped electrode plate.

However, when the carcass is in sliding contact with the electrode plate, an AC square wave is first applied to the positive side first electric wire for a few seconds from the low voltage pulse generator, and then the positive side second electric wire. A sine wave or a half-rectified sine wave is applied to the device for several seconds. Then, the applied low-voltage pulse flows into the body of the anesthetized carcass from the elevated rail via the trolley member and the sling, respectively, and is transmitted to the electrode body, and is returned to the low-voltage pulse generator.
