Abstract

Equipment for separating caps from a tray, after the caps have been attached to bottles to seal the latter. The tray comprises a plurality of fastening systems for holding caps on a lower face of the plate, and a through opening centered on each fastening system, the plurality of openings being distributed according to a distribution pattern. The equipment comprises an unclipping plate provided, on a lower face, with rods distributed according to the distribution pattern. The unclipping plate is mobile along a vertical axis, so that each rod can pass through an opening. Some rods, referred to as first rods, have a first length along the vertical axis and other rods, referred to as second rods, have a second length less than the first length.

First claim

What is claimed is:

1 . Equipment for separating caps from a tray after the caps have been attached to bottles to seal the bottles, the tray comprising a plurality of fastening systems, each fastening system being configured to hold a cap and being arranged on a lower face of the tray, and a through opening centered on each fastening system, the plurality of through openings being distributed over the tray according to a distribution pattern, the equipment comprising:
an unclipping plate comprising a plurality of rods distributed on a lower face of the unclipping plate according to the distribution pattern, the unclipping plate extending in a horizontal plane parallel to an upper face of the tray, and the unclipping plate being mobile along a vertical axis such that each rod of the plurality of rods can pass through an opening of the plurality of through openings, wherein first rods of the plurality of rods have a first length along the vertical axis and second rods of the plurality of rods have a second length less than the first length.

2 . The equipment of claim 1 , wherein the first rods are located in a central region of the lower face of the unclipping plate and the second rods are located in a peripheral region of the lower face of the unclipping plate.

3 . The equipment of claim 1 , wherein the first rods are located in a peripheral region of the lower face of the unclipping plate and the second rods are located in a central region of the lower face of the unclipping plate.

4 . The equipment of claim 1 , wherein the first rods and the second rods are disposed on the lower face of the unclipping plate according to a uniform distribution relative to one another.

5 . The equipment of claim 4 , wherein the uniform distribution is an alternating distribution.

6 . The equipment of claim 1 , wherein the first rods represent between 30% and 70% of all rods of the plurality of rods.

7 . The equipment of claim 1 , wherein a difference between the first length and the second length is between 0.5 mm and 2 mm.

8 . The equipment of claim 1 , further comprising a mechanical device configured to lower the unclipping plate along the vertical axis, the mechanical device comprising a manually actuatable lever, a controllable pneumatic or an electric cylinder.

9 . The equipment of claim 8 , wherein the mechanical device comprises the manually actuatable lever.

10 . The equipment of claim 8 , wherein the mechanical device comprises the controllable pneumatic or the electric cylinder.

11 . The equipment of claim 1 , further comprising a support for holding the tray parallel to the horizontal plane.

12 . The equipment of claim 11 , wherein the support is fixed and configured to immobilize the tray.

13 . The equipment of claim 11 , wherein the support is mobile and configured to move the tray vertically toward the unclipping plate.

14 . The equipment of claim 1 , wherein the unclipping plate comprises between nine rods and one-hundred rods.

15 . The equipment of claim 1 , further comprising a plurality of removable and interchangeable unclipping plates adapted to different trays.

16 . A method for separating caps from a tray, the method comprising:
associating each of the caps with a respective bottle and sealing each cap of the caps to the respective bottle, each of the caps being held in the tray, and the bottles being held in an additional tray; displacing an unclipping plate downward along a vertical axis to a first height to bring first rods of the unclipping plate into contact with upper parts of the caps; and continuing to displace the unclipping plate downward along the vertical axis while holding the tray immobile, the additional tray being vertically moveable until a separation between the caps and the tray; or displacing the tray upward along the vertical axis while holding the unclipping plate immobile at the first height and while holding the additional tray immobile until the separation between the caps and the tray.
