DESCRIPTION:
BRIEF SUMMARY
The present invention concerns a device for the packaging of liquids, more particularly animal semen, and especially boar semen, in flexible pouches intended for artificial insemination and described in particular by the applicants in their French patent 2667504 of Oct. 9, 1990.
To improve the packaging processes of animal semen, the applicants have formed pouches, referred to as dose-pouches packed in the form of a two-layer film roll containing pouches in the form of pre-cut and pre-welded sachets, and a fully automated machine described more particularly in the aforementioned patent for filling, welding and printing said pouches. While offering full satisfaction concerning its general conditions of operation, this machine is more particularly suited to large semen production centers selling doses of semen to major breeders.
For independent breeders having between 300 and 1000 sows to be inseminated and who have not used semen production centers because they use their own boars at the farm, they have neither the utility nor more often than not the financial capability of acquiring such a machine despite all the advantages it offers. In general, it is known that breeders who collect the boar semen at the farm, pack the semen in plastic bottles provided with a screw-on cap. The use of such bottles includes many drawbacks because their cost is relatively high and the multitude of manual manipulations they generate is costly. In addition, the bottles are supplied in bulk and are either in permanent contact with more or less polluted air liable to degrade the quality of the animal semen, thus causing a drop in fertility or risks of contamination within the animal's uterus. Because of their packaging mode, the use of dose pouches eliminates such drawbacks.
It will therefore be seen that the current situation does not facilitate the task of the breeder who collects semen more particularly from boars on the farm and who is unable to use flexible insemination pouches to pack the semen, in particular from the boars.
Therefore, the invention is more specifically designed to eliminate such drawbacks and is specially tailored to the needs and financial means and to the concerns of breeders who collect the boar semen more particularly at the farm and who do not have a sufficiently high number of sows to justify the purchase of an automatic dose pouch packaging machine.
According to the first characteristic of the invention, it is designed for the packaging of liquids and more particularly animal semen, in particular boar semen, in flexible pouches designed for artificial insemination, appearing in the form of a roll of pre-cut bags, pre-perforated and pre-welded, characterized in that it comprises a table provided with tilting means, at least one positioning element at the filling station and/or at the welding station more particularly, designed to hold the pouches correctly, a needle guide forming a device guiding the mobile filling needle so that it is stable and therefore always remains inserted between the two lips of the pouch film and is also constantly in the filling axis, a volume calibrating pallet, a mobile weighted welding pallet connected to an electric supply box upon it and which, by the pressure it applies to the pouch, varying according to the thickness of the pouch film, welds the pouch.
According to other characteristics: located respectively at the left and right ends of the table on the side of the positioning element so that the operator can modify the angle of tilt and thus facilitate the filling of the flexible insemination pouches. In addition, these adjustable feet have a suction device designed to provide total stability of the invention during its use and in particular; positioning studs located at the filling station and/or at the welding station to provide excellent retention and total stability of the pouches during filling then welding operations and, in addition, identification by the affixing of a label to the pouch; flexible pouch welding time, a potentiometer for adjusting the weldin
