Abstract

Described is a centring apparatus, including a conveyor for feeding articles configured for feeding a succession of components, a centring station, positioned downstream of the feeding conveyor and including centring means configured for receiving the components from the feeding conveyor and for centring the components in accordance with a predetermined positioning and/or orientation and a release area, positioned downstream of the centring station for receiving the centred components, coming from the centring station. The apparatus also includes movement means designed to transport the at least one component along a centring path extending from the feeding conveyor to the release area through the centring station.

First claim

1 . A centring apparatus, comprising:
an article feeding conveyor configured for feeding a succession of components and having at least one containing seat adapted to accommodate a respective component; a centring station, disposed downstream of the feeding conveyor and comprising centring means configured for receiving the components from the feeding conveyor and centring the components according to a predetermined position and/or orientation; a releasing area, located downstream of the centring station to receive the centred components from the centring station; movement means, adapted to transport the at least one component along a centring path extending from the feeding conveyor to the releasing area through the centring station.

2 . The apparatus according to claim 1 , wherein the centring means are configured to move the at least one component in translation in a centring plane, preferably horizontal.

3 . The apparatus according to claim 1 , wherein the centring station comprises one or more receiving positions, preferably arranged in one or more rows, and wherein each receiving position comprises a respective support, preferably stationary, for supporting a respective component to be centred, the centring means comprising at least first centring means configured to displace each component relative to the respective support along a first axis while the component is being supported by the support.

4 . The apparatus according to claim 3 , wherein the first centring means comprise, for each receiving position, at least a first engagement surface configured to operatively butt against the at least one component during an operative centring step so as to apply a pushing action on the component along the first axis.

5 . The apparatus according to claim 4 , wherein the first centring means also comprise, for each receiving position, a second engagement surface facing and/or contraposed with the first engagement surface and configured to operatively butt against the at least one component during an operative centring step so as to apply a pushing action on the component along the first axis in the opposite direction relative to the first engagement surface, the first engagement surface and the second engagement surface being preferably movable independently of each other.

6 . The apparatus according to claim 3 , wherein the centring means further comprise second centring means configured to displace each component relative to the respective support along a second axis, transversal and preferably perpendicular to the first axis while the component is being supported by the support.

7 . The apparatus according to claim 6 , wherein the second centring means comprise, for each receiving position, at least a first engagement surface configured to operatively butt against the at least one component during an operative centring step so as to apply a pushing action on the component along the second axis.

8 . The apparatus according to claim 7 , wherein the second centring means also comprise, for each receiving position, a second engagement surface facing and/or contraposed with the first engagement surface and configured to operatively butt against the at least one component during an operative centring step so as to apply a pushing action on the component along the second axis in the opposite direction relative to the first engagement surface, the first engagement surface and the second engagement surface being preferably movable independently of each other.

9 . The apparatus according to claim 4 , wherein the support has a stop surface, in particular a protrusion, defining an abutment for stopping the corresponding component while the pushing action is being applied thereon by the first engagement surface.

10 . The apparatus according to claim 3 , wherein the centring station comprises one or more receiving positions and wherein the first engagement surfaces of the first centring means are defined by the same centring member and/or the second engagement surfaces of the first centring means are defined by the same centring member and/or the first engagement surfaces of the second centring means are defined by the same centring member and/or the second engagement surfaces of the second centring means are defined by the same centring member, the centring members being separate from each other and drivable independently of each other, each centring member being preferably configured like a comb.

11 . The apparatus according to claim 3 , wherein the support, or each support, is rotatable about a respective axis of rotation, preferably stationary, in particular perpendicular to the centring plane.

12 . The apparatus according to claim 3 , wherein the support comprises retaining means, preferably of a pneumatic suction type, to securely retain the respective component.

13 . The apparatus according to claim 1 , wherein the movement means comprise a gripping head, movable between the feeding conveyor and the centring station and between the centring station and the releasing area for releasing the centred components, wherein the gripping head has two gripping regions, each provided with at least one gripping member for at least one respective component, and is configured for transferring at least a first component from the centring station to the releasing area by means of at least one gripping member of the first gripping region and simultaneously transferring at least a second component from the feeding station to the centring station by means of the at least one gripping member of the second gripping region.

14 . The apparatus according to claim 1 , wherein:
the releasing area coincides with an assembly station, for assembling the component to another component, or with a processing station for processing the component; or wherein the movement means also comprise a transfer conveyor located at the releasing area and configured for transferring the centred components, individually or in groups, from the releasing area to an assembly station, for assembling the component to another component, or to a processing station for processing the component, the transfer conveyor preferably comprising a line of independent carriages.

15 . The apparatus according to claim 1 , wherein the feeding conveyor comprises a conveyor belt or chain movable along a respective feed direction comprising a main, rectilinear and/or horizontal conveying stretch, wherein the conveyor belt has receiving zones for supporting respective components, and wherein the movement means are configured to pick up the at least one component at an angled position of the conveyor belt, the angled position being downstream of the main conveying stretch and defining, for the component, a positioning plane different from the positioning plane defined by the main conveying stretch, the angled position being, in particular, defined by a portion of the belt or chain wound around a return pulley.

16 . A method for centring components, comprising the following steps:
feeding at least one component by means of a feeding conveyor; transferring the at least one component from the feeding conveyor to a centring station; positioning the component at a predetermined position, in particular by moving it in a centring plane, preferably horizontal, using centring means, while the component is located in the centring station; transferring the centred component from the centring station to a releasing area.

17 . The method according to claim 16 , wherein the step of transferring the component to the centring station is carried out by positi
