Abstract

Method and apparatus for realizing a continuous and ordered flow ( 50 ) of containers ( 20 ), comprising the steps of:—providing a feed flow ( 30, 30 ′) of containers ( 20 ) arranged with the respective main axes (X-X) randomly oriented; detecting for each container ( 20 ) the position and the orientation of its main axis (X-X), and which of the two main faces (A, B) of the container lies on the transport surface ( 14, 14 ′); picking up ( 12, 12 ′) said containers ( 20 ) from said transport surface ( 14, 14 ′) and releasing said containers ( 20 ) in a first continuous and ordered output flow ( 40 ) in an advancing direction (MD), on a surface ( 18 ) of a first output transport system ( 15 ), wherein said containers are aligned, equidistant (P) from one another, with the respective main axes (X-X) parallel to each other and perpendicular to said advancing direction (MD), picking up ( 62 ) said containers ( 20 ) from said first continuous and ordered output flow ( 40 ), rotating the main axis X-X of each container ( 20 ) by 90° in a first direction, the containers which have a first main face (A) lying on the surface ( 18 ) of the first output transport system ( 15 ), and rotating in a second direction, opposite to the first direction, the containers that have a second main face (B) lying on the surface ( 18 ) of the output first transport system ( 15 ), and depositing ( 62 ) said containers ( 20 ) on a second output transport system ( 70 ), realizing a second continuous and ordered flow ( 50 ) in an advancing direction (MD″) wherein said containers ( 20 ) are aligned, equidistant from each other and with the respective longitudinal axes (X-X) perpendicular to the surface ( 72 ) of said second output transport system ( 70 ), with the filling openings ( 22 ) facing upwards and with the respective main faces (A, B) all oriented in the same direction.

First claim

The invention claimed is:

1. Method for realizing a continuous and ordered flow of containers, wherein said containers have respective filling openings, a main axis, a bottom surface, a first main face and a second main face that connect said opening to said bottom surface said method comprising the steps of:
providing a feed flow of containers in a direction, with a transport system, said containers being arranged with the respective main axis randomly orientated and with one of said two main faces lying on a transport surface of said transport system,
detecting for each container a position and orientation of the main axis, and which of the two main faces lies on the transport surface of said transport system,
picking up said containers from said transport surface of said transport system, and releasing said containers in a first continuous and ordered flow in an advancing direction, on a surface of a first output transport system, wherein said containers are aligned, equidistant from one another with the respective main axes parallel to each other and perpendicular to said advancing direction, where the containers that have the first main face lying on said surface of said first output transport system output are arranged with the respective filling openings facing in a first direction, while the containers that have the second main face lying on said surface of said first output transport system are arranged with the respective filling openings facing in a second direction opposite to the first direction,
transporting said containers of said first continuous and ordered output flow along said advancing direction,
picking up said containers from said first continuous and ordered output flow,
rotating the main axis of each container by 90° in a first direction in a plane perpendicular to the advancing direction of the first continuous and ordered output flow, the containers that have the first main face lying on the surface of the first output transport system of said first output flow, and rotating in a second direction, opposite to the first direction, the containers that have the second main face lying on the surface of the first output transport system of said first output flow,
depositing said containers on a second output transport system, realizing a second continuous and ordered output flow in an advancing direction wherein said containers are aligned, equidistant from one another and with the respective main longitudinal axes perpendicular to the surface of said second output transport system, with filling openings facing upwards and with the respective main faces all oriented in the same direction, and
transporting said containers along said advancing direction of said second continuous and ordered output flow.

2. Method for realizing a continuous and ordered output flow of containers according to claim 1 , wherein the method organizes said containers in said first output flow into groups of consecutive containers, each of said groups of containers being composed of containers that present the same main face lying on the surface of said first output transport system of said first output flow and the respective filling openings all facing in the same direction.

3. Method for realizing a continuous and ordered flow of containers according to claim 2 , wherein consecutive groups of said containers present the filling openings facing in opposite directions.

4. Method for realizing a continuous and ordered flow of containers according to claim 2 , wherein each group of containers includes a number N of containers or one of integer multiples wherein N is between 2 and 50 , and wherein each of said groups of containers have the filling openings facing in the same direction.

5. Method for realizing a continuous and ordered flow of containers according to claim 4 , wherein N is between 3 to 10.

6. Method for realizing a continuous and ordered flow of containers according to claim 2 , wherein each group of consecutive containers is composed of the same number N of containers.

7. Method for realizing a continuous and ordered flow of containers according to claim 6 , wherein the method comprises simultaneously picking up a multiple of N of said containers from said first continuous and ordered output flow.

8. Method for realizing a continuous and ordered flow of containers according to claim 1 , wherein said advancing direction of said second continuous and ordered output flow is parallel to the advancing direction of said first continuous and ordered output flow of said containers.

9. Device suitable for realizing a continuous and ordered flow of containers, wherein said containers present respective filling openings and a main axis, a bottom surface, a first main face and a second main face connecting said opening to said bottom surface, said device comprising:
a feed transport system, configured for advancing a respective flow of containers along a feed direction, said containers being arranged with the respective main axes randomly oriented and with one of said main faces lying on a surface of said feed transport system,
at least one control means capable of detecting a position and orientation of the main axis of each container and which of the two main faces is lying on the surface of said feed transport system,
a first output transport system, arranged for advancing a first continuous and ordered output flow of said containers along an advancing direction, and
at least one gripping means positioned in close proximity to said feed transport system of said feed flow and said first output transport system configured to pick up said containers from said feed flow and to deposit them on a surface of said first output transport system in a first continuous and ordered output flow wherein said containers are aligned, equidistant between them, with the respective main axes parallel to each other and perpendicular to said advancing direction, where the containers that have a first main face lying on said surface of said first output transport system of said first continuous and ordered output flow are arranged with the respective filling openings facing in a first direction, while the containers that have the second main face lying on said surface of said first output transport system of said first continuous and ordered output flow are arranged with the respective filling openings facing in a second direction opposite to the first direction,
