Abstract

Slaughter animals and esp. pigs are stunned using an electric shock whilst restrained between two conveyor belts in the form of a Vee. As each pig approaches the stunning device, it comes into contact with two sets of electrodes. The first set consist of several parallel electrodes hinged about a horizontal axis perpendicular to the length of the conveyor and held in the downward position by springs. The second set consist of a pair of parallel electrodes similarly supported but with their lower ends bent toward the front of the conveyor. As the pig is carried by the restrainer it first comes into contact with the rearmost electrode. As it moves further forward, its head and, preferably, its eyes come into contact with the front electrodes. The consequent closure of the circuit between the two electrodes causes a sensing current to flow which is immediately followed by a strong, stunning shock. After this, a timer prevents any further flow of current until the pig is clear of the stunner. This prevents the pig behind from causing a premature discharge of current. Prior art required manual contacting of electrodes with the pig from behind. This requires considerable physical strength from the person carrying out the stunning and delivers a shock of uncertain strength and duration to the muscles in the neck of the pig. Such a shock may cause muscular contractions which damage the inside of the pig. The above device eliminates the need for hand placing of the electrodes and passes a precisely sized and timed shock into the brain of the pig thus causing immediate stunning with no muscle spasms.

Description

9- NO 30 7989- NO 30 798

Inrichting voor het verdoven van slachtvee.Device for the stunning of beef cattle.

Afsplitsing van de Nederlandse octrooiaanvrage 7705519.Division of the Dutch patent application 7705519.

De uitvinding heeft betrekking op een inrichting voor het verdoven van slachtvee, in het bijzonder van varkens, bestaande uit t\i/ee met de werkvlakken V-vormig opgestelde synchroon en evenwijdig aan elkaar lopende transportbanden onzer einde met aan het invoereinde van deze 5 transportbanden daaronder een vloer, die in de looprichting van de banden een toenemende afstand tot deze.banden heeft.The invention relates to a device for the stunning of slaughtered cattle, in particular of pigs, consisting of conveyors arranged in a V-shaped manner in a V-shaped manner and with conveyor belts running parallel to each other at the end of these conveyor belts underneath a floor, which has an increasing distance to these tires in the running direction of the tires.

Een dergelijke inrichting is bekend uit het Amerikaanse octrooi-schrift 2.185.949. Bij deze bekende inrichting wordt het tussen de een V-vormige doorgang bepalende transportbandeningeklemde dier verdoofd 10 met behulp van een elektrische verdovingsstang die door een bedieningsman wordt gehanteerd. Bij deze bekende inrichtingen kan zich het probleem voordoen dat de tussen de werkvlakken in geklemde dieren te dicht op elkaar aansluiten. Dit komt doordat de dieren in de vóór de inrichting gelegen gang elkaar opjagen respectievelijk door het personeel van het 15 slachthuis worden opgejaagd. Hebben de dieren onvoldoende afstand tot elkaar dan kunnen zich moeilijkheden voordoen bij het elektrisch verdoven doordat het met de elektroden in aanraking komende dier ook in aanraking is met een ander dier dat dan ook een schok krijgt, die echter eerder schadelijk is dan nuttig. Het te dicht op elkaar aansluiten van dieren 20 heeft bovendien tot gevolg dat de verdoofde dieren te dicht op elkaar volgen waardoor zich moeilijkheden voordoen bij het aanketten, dat wil zeggen het door middel van een om een poot aan te brengen ketting, en het inhaken van deze ketting aan een transportmiddel afvoeren van de dieren naar de plaats waar het steken moet worden uitgevoerd.Such a device is known from United States Patent Specification 2,185,949. In this known device, the animal clamped between the V-shaped passageway and the conveyor belt clamped is anesthetized with the aid of an electric anesthetic rod which is operated by an operator. With these known devices the problem can arise that the animals clamped between the working surfaces are too close together. This is because the animals chase each other in the corridor located before the establishment or are chased by the slaughterhouse staff. If the animals do not have sufficient distance from each other, difficulties can be encountered in the electric stunning, because the animal that comes into contact with the electrodes also comes into contact with another animal, which therefore receives a shock, which however is more harmful than useful. Connecting animals 20 too closely together also causes the anesthetized animals to follow one another too closely, causing difficulties in dressing, i.e., by means of a chain to be attached to a leg, and hooking remove this chain from the animals on a means of transport to the place where the stabbing must be carried out.

25 Doel van de uitvinding is nu een inrichting te verschaffen waarbij zich deze bezwaren niet voordoen.The object of the invention is now to provide a device in which these drawbacks do not arise.

Dit doel wordt nu overeenkomstig de uitvinding bereikt doordat vóór de V-vormig opgestelde uit transportbanden zonder einde bestaande inrichting een tweede soortgelijke inrichting is geplaatst, die eveneens 30 bestaat uit twee V-vormig opgestelde synchroon en evenwijdig aan elkaar lopende transportbanden zonder einde waarvan de werkvlakken liggen in dezelfde vlakken als de werkvlakken van de erop aansluitende transportbanden zonder einde van de eerstgenoemde inrichting en waarbij de snelheid van de transportbanden van de inrichting waar de invoer plaats vindt, 35 lager is dan van de daarop volgende inrichting. Door het verschil in snelheid worden de dieren van elkaar gescheiden waarbij zich het merkwaar- 8200944 -2- dige en verrassende verschijnsel voordoet dat de dieren bij de overgang van de ene in richting in de volgende niet worden geïrriteerd door de met hogere snelheid aangrijpende banden.This object is now achieved according to the invention in that a second similar device is placed in front of the V-shaped endless conveyor belts, which device likewise consists of two V-shaped arranged synchronous and parallel conveyor belts without end, the working surfaces of which lie in the same planes as the working surfaces of the adjoining endless conveyor belts of the former device and wherein the speed of the conveyor belts of the device where the input takes place is lower than that of the subsequent device. Due to the speed difference, the animals are separated from each other, with the remarkable and surprising phenomenon that the animals are not irritated by the bands that move at a higher speed during the transition from one direction to the next.

, Op zichzelf is het in de transporttechniek bekend aaneengesloten 5 reeksen van voorwerpen van elkaar te scheiden met behulp van transportmiddelen, die met toenemende snelheid de voorwerpen overnemen.It is known per se in the transport technique to separate contiguous series of objects from one another by means of transport means which take over the objects with increasing speed.

Bij dieren betekent dit echter dat de met hogere snelheid lopende transportbanden al aan het ingeklemde dier beginnen te trekken wanneer het achtergedeelte nog is ingeklemd in de met lagere snelheid lopende 10 banden. Het probleem van de te dicht op elkaar aansluitende dieren is ook al een oud probleem dat men op de koop toe nam op grond van de wetenschap dat irritatie van het dier nadelig is voor de kwaliteit van hefylees,In animals, however, this means that the higher speed conveyor belts already begin to pull on the clamped animal when the rear portion is still clamped in the lower speed conveyor belts. The problem of animals that are too close to each other is also an old problem that was put on the market because of the knowledge that irritation of the animal is detrimental to the quality of hefylees,

De uitvinding zal thans nader worden toegelicht aan de hand van 15 de tekeningen:The invention will now be further elucidated with reference to the drawings:

Fig. 1 toont de inrichting volgens de uitvinding in zijaanzicht met weglating van niet-essentiële delen.Fig. 1 shows the device according to the invention in side view with the omission of non-essential parts.

Fig. 2 toont een vooraanzicht.Fig. 2 shows a front view.

De in de tekening getoonde inrichting bestaat uit de op zichzelf 20 bekende transportbanden 1 en 2, die de in fig. 2 getoonde V-vormige doorgang bepalen. Nabij het afvoereinde zijn op de wijze beschreven in de Nederlandse octrooiaanvrage 7705519, waarvan de onderhavige aanvrage een afsplitsing vormt, elektroden 5 en 6 aangebracht die kunnen zwaaien om horizontale scharnierassen 7 en 8 en door veren 9 en 10 op hun 25 plaats worden gehouden.The device shown in the drawing consists of the conveyor belts 1 and 2 known per se, which define the V-shaped passage shown in Fig. 2. Near the discharge end, electrodes 5 and 6, which can pivot about horizontal pivot shafts 7 and 8 and are held in place by springs 9 and 10, are arranged in the manner described in Dutch patent application 7705519, of which the present application forms a division.

Overeenkomstig de uitvinding zijn nu vóór de transportbanden 1 en 2 overeenkomstig uitgevoerde transportbanden 1’,2' geplaatst, waarvan de naar elkaar toe gekeerde werkvlakken, die de V-vormige doorgang bepalen, in dezelfde vlakken liggen als de werkvlakken van 30 de transportbanden 1 en 2.According to the invention, correspondingly designed conveyor belts 1 ', 2' are now placed in front of the conveyor belts 1 and 2, the working surfaces of which face each other, which define the V-shaped passage, lie in the same planes as the working surfaces of the conveyor belts 1 and 2. 2.

De invoerrichting is aangegeven met de pijl 4 en de dieren komen bij het invoereinde aan via de bodem 3 die bij voorkeur reeds in de eerste inrichting, die wordt gevormd door de banden 1',2', schuin naar beneden verloopt, dat de dieren geen steun meer voor de 35 poten vinden en ingeklemd raken tussen de werkvlakken van de banden.The feed direction is indicated by the arrow 4 and the animals arrive at the feed end via the bottom 3, which preferably already slopes downwards in the first device, which is formed by the belts 1 ', 2', so that the animals do not find more support for the 35 legs and get wedged between the working surfaces of the belts.
