Abstract

Apparatus for extracting pharmaceutical containers from a nest inside a tub includes an advancement line of the tubs, which stops the tubs at a rest station; a handling organ, and a pickup and transfer station. The station has a frame, with a housing for receiving and supporting a nest and rotatable about a first axis into a first operating position near the rest station and into a second operating position near the handling organ. A suction gripper collects at least a further nest containing pharmaceutical containers from a tub in the rest station and positions the further nest in the housing of a second frame stationary in the first operating position. The second frame then rotates into the second operating position for the handling organ to collect the pharmaceutical containers from the “nest.”

First claim

The invention claimed is:

1. An apparatus for extracting pharmaceutical containers to be filled from relative support elements constituted by a nest arranged internally of a tub, wherein the pharmaceutical containers have respective mouths for insertion of a pharmaceutical substance or product and are arranged and supported by the nest with the respective mouths for insertion of a pharmaceutical substance or product facing upwards, the apparatus comprising:
an advancement line, for advancing the tubs, with the nests inside them containing the pharmaceutical containers, and for stopping the tubs at a rest station;
a handling organ;
a pickup and transfer station, for picking up the nests containing the pharmaceutical containers from the tubs which have been positioned by the advancement line in the rest station,
wherein the pickup and transfer station comprises:
at least a frame conformed as to have at least a housing having a shape and dimensions to be able to receive and support a nest with the pharmaceutical containers inside, the frame being predisposed to be activatable in rotation about a first rotation axis in order to be positionable in a first operating position, in which the housing is situated in proximity of the rest station of the advancement line, and in a second operating position in which the housing is in proximity of the handling organ,
gripping means by suction, configured to collect, by suction, at least a nest containing the pharmaceutical containers from a relative tub positioned by the advancement line at the rest station, the gripping means by suction are further configured and activatable, when the frame is positioned in the first operating position, in order to extract, gripping by suction, the nest containing the pharmaceutical containers from the tub and to transfer, position and release the nest in the housing of the frame,
with the frame, once the gripping means have positioned and released the nest containing the pharmaceutical containers in the housing, being activatable in rotation about the first rotation axis so as to be positioned in the second operating position so that the housing, with the nest containing the pharmaceutical containers, is in proximity of the handling organ, the frame also being configured and predisposed so that, during the rotation about the first rotation axis from the first operating position to the second operating position, the frame can also be set in rotation about a second rotation axis parallel to the first rotation axis, so that the housing, and therefore the nest containing the pharmaceutical containers, remains parallel to and constantly maintains a same orientation with respect to the first rotation axis during the displacement from the first operating position to the second operating position,
and wherein the handling organ is predisposed and configured to grip, handle, move and release the pharmaceutical containers, so that, when the frame has been positioned in the second operating position with the relative housing containing the nest with the pharmaceutical containers, the handling organ can be activatable to grip a group of pharmaceutical containers and extract them from the nest and repeat such operations up to completely emptying the nest,
wherein the frame, in order to be movable from the first operating position to the second operating position, is configured to be activatable about the first rotation axis according to a curved trajectory with a prefixed rotation direction so that the frame, and therefore the housing with nest containing the pharmaceutical containers, is first raised with respect to the advancement line and then lowered, in order to be positioned in the second operating position in proximity of the handling organ.

2. The apparatus as claimed in claim 1 , wherein the frame, in order to be movable from the second operating position to the first operating position, after the handling organ has collected all the pharmaceutical containers and emptied the nest borne by the housing of the frame positioned in the second operating position, is configured to be activatable about the first rotation axis always in the prefixed rotation direction according to a curved trajectory so that the frame, and therefore the housing with the emptied nest, is first lowered and then raised so as to be positioned in the first operating position in proximity of the rest station of the advancement line, and wherein the gripping means by suction, when the frame with the housing containing the emptied nest is returned into the first operating position, are further configured to be activatable to grip by suction the emptied nest, extract it from the housing and reposition it in the tub on the advancement line from which it had previously been extracted.

3. The apparatus as claimed in claim 1 , wherein the frame is borne by a pair of arms, the pair of arms being rotatably mounted on relative support elements so that the pair of arms is activatable in rotation with respect to the support elements about the first rotation axis so that, with the rotation of the pair of arms with respect to the support elements, the frame can be activated in rotation about the first rotation axis and moved from the first operating position to the second operating position and vice versa, and wherein the frame is mounted on the pair of arms to be rotatable with respect to the pair of arms according to the second rotation axis, so that, during the movement from the first operating position to the second operating position, and vice versa, the frame, and therefore the relative housing, remains parallel and keeps the same orientation with respect to the first rotation axis.

4. The apparatus as claimed in claim 3 , wherein the second frame is also borne by the pair of arms mounted rotatably on the support elements, the pair of arms being activatable in rotation with respect to the support elements about the first rotation axis to activate the frame and the second frame in rotation about the first rotation axis and move the frame from the first operating position to the second operating position and, at the same time, the second frame from the second operating position to the first operating position, and vice versa, and wherein the second frame is mounted on the pair of arms to be rotatable with respect to the pair of arms according to the third rotation axis, so that, during the movement from the first operating position to the second operating position, and vice versa, the second frame, and therefore the relative housing, remains parallel and keeps the same orientation with respect to the first rotation axis.

5. The apparatus as claimed in claim 1 , wherein the frame comprises a rest plane predisposed inferiorly of the housing at a distance so that, when the frame is in the first operating position and the nest containing the pharmaceutical containers is positioned by the gripping means in the housing, the lower end of the pharmaceutical containers abuts the rest plane so that the pharmaceutical containers are partially raised with respect to the nest so that an upper part thereof projects from the nest to facilitate gripping thereof by the handling organ.

6. The apparatus as claimed in claim 5 , wherein the frame comprises a matrix of centering through-seats predisposed in the housing, above the rest plane, each of the through-seats being destined to house, and enable free passage of, relative pharmaceutical containers when the nest containing the pharmaceutical containers is positioned by the gripping means in the housing of the frame, so as to maintain the pharmaceutical containers correctly orientated during the movement of the frame from the first operating position to the second operating position.

7. The apparatus as claimed in claim 1 , wherein th
