Device for automatically taking liquid from a bottle

Claim 1

In a device for automatically taking liquid from a bottle presented upside down opposite a sample taking needle intended to pierce the stopper of the bottle and penetrate into the liquid, including a mobile support for storing a plurality of bottles and moving a bottle into a preselected position with respect to a stopper piercing assembly, said assembly including a mobile block serving as a support for the sample taking needle and being movable under the action of an actuating cylinder, with the sample taking needle being essentially centered on the mobile block, and a rinsing receptacle which is fixedly mounted and through which the needle passes, wherein said mobile block slides on two fixed vertical guide columns between which the actuating cylinder is operatively connected to the mobile block essentially at the middle of the block, and between which the sample taking needle moves vertically by transmission of the action of the actuating cylinder by transmission of a horizontal movement produced therewith, and wherein a fixed spacer is mounted on the two columns at their upper ends and serves as a support for the rinsing receptacle.

Claim 12

A device for automatically taking liquid from bottles each having a stopper in one end, wherein each of the bottles is automatically moved into a sample taking position with the bottle inverted, which comprises: vertically movable block means for supporting an elongated vertically extending sample taking needle beneath and in essentially vertical alignment with the sample taking position; a pair of spaced vertically extending guide means located on opposite sides of a path of travel of the elongated sample taking needle toward and away from the sample taking position, for guiding the support block means and the needle for vertical movement in a sample taking operation; rinsing receptacle means fixedly mounted between the pair of spaced vertically extending guide means and through which the sample taking needle passes, for rinsing the needle after the sample taking operation; actuating cylinder means movable horizontally for moving the support block means and the sample taking needle vertically upward toward one of the bottles in the sample taking position so that the needle pierces the stopper in the bottle, and for moving the support block means and the sample taking needle vertically downward after the sample taking operation; and means for connecting the actuating cylinder means to the support block means essentially centrally between the pair of spaced vertically extending guide means and in substantially vertical alignment with the sample taking needle to prevent jamming during the sample taking operation.

Claim 13

A device for automatically taking liquid from bottles each having a stopper in one end, wherein each of the bottles is automatically moved into a sample taking position with the bottle inverted, which comprises: vertically movable block means for supporting an elongated vertically extending sample taking needle beneath and in essentially vertical alignment with the sample taking position; a pair of spaced vertically extending guide means located on opposite sides of a path of travel of the elongated sample taking needle toward and away from the sample taking position, for guiding the support block means and the needle for vertical movement in a sample taking operation; rinsing receptacle means fixedly mounted between the pair of spaced vertically extending guide means and through which the sample taking needle passes, for rinsing the needle after the sample taking operation; actuating cylinder means movable horizontally for moving the support block means and the sample taking needle vertically upward toward one of the bottles in the sample taking position so that the needle pierces the stopper in the bottle, and for moving the support block means and the sample taking needle vertically downward after the sample taking operation; and means for connecting the actuating cylinder means to the support block means essentially centrally between the pair of spaced vertically extending guide means and in substantially vertical alignment with the sample taking needle to prevent jamming during the sample taking operation.
