Abstract

A milking arrangement includes plural milking places, each milking place having a primary end and an opposite secondary end, an entrance at the primary end, a front side and a rear side, which both extend in parallel with the longitudinal axis, a plurality of sequence gates arranged between the front side and the rear side, each of the sequence gates being pivotable between a closed position and an open position, each sequence gate being only pivotable from its closed position to its open position in a pivotation direction in which the front end is pivoted into a milking place towards the front side of the milking arrangement, main extension planes of the sequence gates being aligned when the sequence gates are in their closed position, with a lower edge of each sequence gate defining a bulge that extends downwards.

First claim

The invention claimed is:

1. A milking arrangement comprising:
a plurality of milking places ( 1 ) arranged side by side after each other along a longitudinal axis (x), each of the milking places ( 1 ) having a width (W) and being configured to receive a respective animal to be milked;
a primary end ( 3 ) and a secondary end ( 4 ) opposite to the primary end ( 3 ), wherein the milking arrangement extends along the longitudinal axis from the primary end ( 3 ) to the secondary end ( 4 );
an entrance ( 5 ) at said primary end ( 3 );
a front side ( 6 ) and a rear side ( 7 ), the front side ( 6 ) and the rear side ( 7 ) both extending in parallel with the longitudinal axis (x); and
a plurality of sequence gates ( 10 ) arranged between said front side ( 6 ) and said rear side ( 7 ),
wherein each of said sequence gates ( 10 ) is pivotable between a closed position, in which each of said sequence gates ( 10 ) defines a temporary barrier against entrance into each of two neighbouring ones of the milking places ( 1 ), and an open position in which each of said sequence gates ( 10 ) forms a side wall between said two neighbouring ones of the milking places ( 1 ),
wherein each of said sequence gates ( 10 ) has a front end ( 11 ), which, in the closed position of the sequence gate ( 10 ), is directed towards said secondary end ( 4 ) of the milking arrangement, and a rear end ( 12 ), which in the closed position of the sequence gate ( 10 ), is directed towards said primary end ( 3 ) of the milking arrangement,
wherein each of said sequence gates ( 10 ) is only pivotable from the closed position to the open position in a pivotation direction in which said front end ( 11 ) is pivoted into one of the milking places ( 1 ) towards the front side ( 6 ) of the milking arrangement,
wherein main extension planes of the sequence gates ( 10 ) are in alignment when the sequence gates ( 10 ) are in the closed position,
wherein each of said sequence gates ( 10 ) has a lower edge ( 15 ) extending from said rear end ( 12 ) to said front end ( 11 ) of the sequence gate ( 10 ),
wherein, at a lower rear end ( 12 a ) of each of said sequence gates, where said lower edge ( 15 ) meets an edge of said rear end ( 12 ), said lower edge ( 15 ) is at a first level, and
wherein, in a region where the lower edge ( 15 ) meets an edge of said front end ( 11 ), the lower edge ( 15 ) defines a bulge ( 16 ) that extends downwards to a lower, second level such that the second level of a first of the sequence gates is lower than the first level of the lower rear end ( 12 a ) of a neighbouring second of the sequence gates ( 10 ), the first of the sequence gates ( 10 ) being located closer to the primary end ( 3 ) of the milking arrangement than the neighbouring second of the sequence gates ( 10 ).

2. The milking arrangement according to claim 1 ,
wherein the rear end ( 12 ) of each of said sequence gates ( 10 ) has a recess ( 18 ) and the front end ( 11 ) of each of said sequence gates ( 10 ) has a nose portion ( 19 ), and
wherein said nose portion ( 19 ) of the first of the sequence gates ( 10 ) extends into the recess ( 18 ) of the neighbouring second of the sequence gates ( 10 ) when both the first and the neighbouring second of the sequence gates ( 10 ) are in the closed position.

3. The milking arrangement according to claim 2 , wherein the nose portion ( 19 ) of each of said sequence gates ( 10 ) extending from a pivoting point of the sequence gate ( 10 ) towards the secondary end ( 4 ) of the milking arrangement covers at least 30% of the width (W) of the milking place ( 1 ) when the sequence gate ( 10 ) is in the closed position.

4. The milking arrangement of claim 1 , wherein,
each of said sequence gates ( 10 ) is arranged to pivot at a pivoting point around a structural member ( 22 ), and
the bulge ( 30 ) is located between the structural member ( 22 ) and the front end ( 11 ) of the sequence gate ( 10 ),
an upper part of each of said sequence gates ( 10 ) extending from the pivoting point ( 21 ) of the sequence gate towards the primary end ( 3 ) covers at least 50% of the width (W) of the milking place ( 1 ) when the sequence gate ( 10 ) is in the closed position,
a lower part of each of said sequence gates ( 10 ) extending from the pivoting point ( 21 ) of the sequence gate ( 10 ) towards the primary end ( 3 ) of the milking arrangement covers at least 50% of the width (W) of the milking place ( 1 ) when the sequence gate ( 10 ) is in the closed position,
there is a gap ( 20 ) between a rear end edge and a front end edge of neighbouring ones of the sequence gates ( 10 ) when the sequence gates ( 10 ) are in the closed position, and
said gap has a width (w) which is less than 10 cm along at least 80% of a total length of the gap ( 20 ),
further comprising a drive device ( 23 ) for moving the sequence gates ( 10 ) from a lower position in which the sequence gates ( 10 ) are at a level of animals standing in the milking places ( 1 ) to a second position, which is an elevated position in which the sequence gates ( 10 ) are located at a level above and behind animals standing in the respective milking places ( 1 ), wherein the sequence gates ( 10 ) are configured to move from said second position to the lower position with the sequence gates ( 10 ) in the closed position such that the sequence gates ( 10 ) urge animals standing in respective milking places ( 1 ) to move towards the front side ( 6 ) to leave the milking places ( 1 ) through the front side ( 6 ),
wherein the second level to which the bulge ( 16 ) of the first of the sequence gates ( 10 ) extends downwards to is at least 3 cm below the first level at the lower rear end ( 12 a ) of the neighbouring second sequence gate ( 10 ),
each of said sequence gates comprises a flat sheet that extends from the front end ( 11 ) to the rear end ( 12 ) and down to the bulge of the lower edge ( 15 ) of the sequence gate, and
main extension planes of the flat sheets are in alignment when the sequence gates ( 10 ) are in the closed position.

5. The milking arrangement according to claim 1 , wherein each of said sequence gates ( 10 ) is arranged to pivot around a pivoting point ( 21 ).

6. The milking arrangement according to claim 5 , wherein an upper part of each of said sequence gates ( 10 ) extending from the pivoting point ( 21 ) of the sequence gate towards the primary end ( 3 ) covers at least 50% of the width (W) of the milking place ( 1 ) when the sequence gate ( 10 ) is in the closed position.

7. The milking arrangement according to claim 5 , wherein a lower part of each of said sequence gates ( 10 ) extending from the pivoting point ( 21 ) of the sequence gate ( 10 ) towards the primary end ( 3 ) of the milking arrangement covers at least 50% of the width (W) of the milking place ( 1 ) when the sequence gate ( 10 ) is in the closed position.

8. The milking arrangement according to claim 1 ,
wherein there is a gap ( 20 ) between a rear end edge and a front end edge of neighbouring ones of the sequence gates ( 10 ) when the sequence gates ( 10 ) are in the closed position, and
wherein said gap has a width (w) which is less than 10 cm along at least 80% of a total length of the gap ( 20 ).

9. The milking arrangement according to claim 1 , wherein each of said sequence gates ( 10 ) comprises an opaque sheet.

10. The milking arrangement according to claim 1 , further comprising a drive device ( 23 ) for moving the sequence gates ( 10 ) from a lower position in which the sequence gates ( 10 ) are at a level of animals standing in the milking places ( 1 ) to a second position, which is an elevated position in which the sequence gates ( 10 ) are located at a level above and behind anim
