Abstract

A device for conveying a cap-type capping elements, which are pushed aeraulically to circulate the capping elements in a forward direction. In example embodiments, the device includes firstly an elongate plenum in which a gaseous fluid circulates, and secondly a channel in which the capping elements circulate in a forward direction and that has a front face, a rear face, and two edge faces. In example embodiments, the device comprises an aeraulic circuit to convey the gaseous fluid from the plenum to the channel to push the capping elements, the rear face of said channel being arranged against the plenum and the front face thereof being at least partially closed by a back-plate of the device. In example embodiments, the back-plate may be removable.

First claim

The invention claimed is:

1 . A device for conveying a cap-type capping element, in which the capping elements are pushed aeraulically, said device comprising firstly an elongate plenum in which a gaseous fluid circulates, and secondly a channel in which the capping elements circulate in a forward direction and that has a front face, a rear face, and two edge faces, at least one of the two edge faces disposed below the capping elements being conveyed along the channel and the other of the two edge faces disposed above the capping elements being conveyed along the channel,
wherein the device comprises an aeraulic circuit to convey the gaseous fluid from the plenum to the channel to push the capping elements, the rear face of said channel being arranged against the plenum and the front face thereof being at least partially closed by a back-plate of the device, the aeraulic circuit opening into the channel through at least one edge face.

2 . The device according to claim 1 , further comprising at least one distributor arranged against the plenum, the aeraulic circuit being arranged in said at least one distributor.

3 . The device according to claim 2 , wherein the aeraulic circuit formed in the at least one distributor comprises firstly a cavity for receiving the gaseous fluid from the plenum, and secondly injectors in the form of grooves that extend from said cavity and open into the channel through at least one edge face to inject the gaseous fluid into said channel and to push the capping elements.

4 . The device according to claim 3 , wherein the injectors are oblique in relation to the edge face in which they open, so that the flow that they create has a component in the forward direction to move the capping elements.

5 . The device according to claim 2 , therein the at least one distributor is removably fastened to the plenum.

6 . The device according to claim 2 , wherein it comprises two distributors, each at an edge face, the aeraulic circuit extending into each of the two distributors so that the gaseous fluid reaches the two edge faces of the channel, preferably symmetrically.

7 . The device according to claim 2 , further comprising a front wall delimiting the plenum on the side of the channel and having at least one orifice enabling the gaseous fluid to circulate from the plenum into the aeraulic circuit.

8 . The device according to claim 2 , wherein the at least one back-plate is removably mounted to the at least one distributor.

9 . The device according to claim 8 , wherein the at least one plate is adjustably mounted, notably to adjust the width of a slot in the front face.

10 . The device according to claim 2 , wherein the device comprises two back-plates on the front face arranged in line with one another.

11 . A distributor for the device according to claim 1 , the distributor configured to convey air flow into the channel of the device.

12 . A method for aeraulically moving cap-like capping elements in an elongate channel that is as a whole rectilinear in a forward direction and of rectangular section, and that has a front face, a rear face, and two edge faces, at least one of the two edge faces disposed below the capping elements moving along the channel and the other of the two edge faces disposed above the capping elements moving along the channel, the capping element having a disk that circulates against the front face or against the rear face, in which method a gaseous fluid is injected into the channel to push the capping elements therein, and to move them in a forward direction, wherein
the gaseous fluid is injected into the channel from at least one of the edge faces.

13 . The method according to claim 12 , wherein the gaseous fluid is injected into the channel from each of the two edge faces facing one another.

14 . The method according to claim 13 , wherein the gaseous fluid is injected into the channel symmetrically, each time from one of the edge faces to the other and partially in the forward direction.

15 . The method according to claim 13 , wherein the gaseous fluid is injected into the channel at an orientation such that a component thereof extends in the forward direction.

16 . The method according to claim 12 , wherein the gaseous fluid is injected into the channel at an orientation such that a component thereof extends in the forward direction.

17 . The method according to claim 16 , wherein the gaseous fluid is injected into the channel symmetrically, each time from one of the edge faces to the other and partially in the forward direction.

18 . A device for conveying a cap-type capping element, in which the capping elements are pushed aeraulically, said device comprising firstly an elongate plenum in which a gaseous fluid circulates, and secondly a channel in which the capping elements circulate in a forward direction and that has a front face, a rear face, and two edge faces,
wherein the device comprises an aeraulic circuit to convey the gaseous fluid from the plenum to the channel to push the capping elements, the rear face of said channel being arranged against the plenum and the front face thereof being at least partially closed by a back-plate of the device, the aeraulic circuit opening into the channel through at least one edge face, and wherein the capping elements within the channel remain contained therein without projecting external the channel beyond the back-plate.
