Abstract

Stop device ( 1 ) for a conveyor system ( 40 ) where objects ( 43 ) are conveyed on a conveyor ( 41 ), where the stop device ( 1 ) comprises a housing ( 2 ), an actuator element ( 3 ) having a stop surface ( 12 ), and an electric motor ( 4 ) operably connected to the actuator element ( 3 ) such that the electric motor ( 4 ) can control the position of the actuator element ( 3 ), where the stop device comprises a stop position ( 20 ) in which the stop device ( 1 ) will hold an object ( 43 ) in a fixed position by the stop surface ( 12 ), and a bypass position ( 22 ) in which the stop surface ( 12 ) is positioned outside of a contact plane ( 42; 96 ) of the object ( 43 ) such that the object ( 43 ) can pass the stop device ( 1 ), where the actuator element ( 3 ) is provided with a braking surface ( 13 ), where the stop device ( 1 ) comprises a braking position ( 21 ) in which the braking surface ( 13 ) is positioned in the contact plane ( 42; 96 ) such that the object ( 43 ) will bear against the braking surface ( 13 ) and such that the speed of an object ( 43 ) will slow down from a first speed to a standstill, and where the electric motor ( 4 ) can move the actuator element ( 3 ) between the stop position ( 20 ), the braking position ( 21 ) and the bypass position ( 22 ). The advantage of the invention is that a reliable and cost-effective stop device comprising a brake function for an object such as a product or a pallet conveyed in a conveyor system is provided. The application also includes a conveyor system comprising a stop device.

Claims (27)

1 . Stop device ( 1 ) for a conveyor system ( 40 ) where objects ( 43 ) are conveyed on a conveyor ( 41 ), the stop device ( 1 ) comprising:

a housing ( 2 ),

an actuator element ( 3 ) having a stop surface ( 12 ),

an electric motor ( 4 ) operably connected to the actuator element ( 3 ) such that the electric motor ( 4 ) can control the position of the actuator element ( 3 ),

a stop position ( 20 ) in which the stop device ( 1 ) will hold an object ( 43 ) in a fixed position by the stop surface ( 12 ), and

a bypass position ( 22 ) in which the stop surface ( 12 ) is positioned outside of a contact plane ( 42 ; 96 ) of the object ( 43 ) such that the object ( 43 ) can pass the stop device ( 1 ),

wherein:

the actuator element ( 3 ) is provided with a braking surface ( 13 ),

the stop device ( 1 ) further comprises a braking position ( 21 ) in which the braking surface ( 13 ) is positioned in the contact plane ( 42 ; 96 ) of the object ( 43 ), such that the object ( 43 ) will bear against the braking surface ( 13 ) and such that the speed of an object ( 43 ) will slow down from a first speed to a standstill,

the electric motor ( 4 ) can move the actuator element ( 3 ) between the stop position ( 20 ), the braking position ( 21 ) and the bypass position ( 22 ), and

the actuator element ( 3 ) is connected to the electric motor ( 4 ) through an axle ( 9 ) suspended in the housing ( 2 ) by a first bearing ( 7 ) and a second bearing ( 8 ).

2 . Stop device according to claim 1 , wherein the braking surface ( 13 ) can be fine adjusted by the electric motor ( 4 ) in the braking position ( 21 ) between a forward contact point ( 23 ) and a rear contact point ( 24 ).

3 . Stop device according to claim 2 , wherein the braking surface ( 13 ) is adjusted in the braking position ( 21 ) depending on the weight of an object ( 43 ) that is to be stopped.

4 . Stop device according to claim 2 , wherein the braking surface ( 13 ) is adjusted in the braking position ( 21 ) depending on the speed of an object ( 43 ) that is to be stopped.

5 . Stop device according to claim 1 , wherein the braking surface ( 13 ) of the stop device ( 1 ) is arranged to be positioned in a horizontal direction at a conveyor.

6 . Stop device according to claim 5 , wherein the actuator element ( 3 ) is connected to the electric motor ( 4 ) through a pivot element ( 15 ) arranged on the axle ( 9 ) and that the actuator element ( 3 ) is attached to the pivot element with a pivot pin ( 17 ) through a pivot slot ( 16 ).

7 . Stop device according to claim 5 , wherein the actuator element ( 3 ) comprises a retention slot ( 18 ) arranged at a front end of the actuator element ( 3 ), and that a retention pin ( 19 ) attaches the actuator element ( 3 ) to the housing ( 2 ).

8 . Stop device according to claim 5 , wherein the stop surface ( 12 ) of the actuator element ( 3 ) is arranged at the rear part of the actuator element ( 3 ).

9 . Stop device according to claim 1 , wherein the braking surface ( 13 ) of the stop device ( 1 ) is arranged to be positioned in a vertical direction at a conveyor.

10 . Stop device according to claim 9 , wherein the actuator element ( 3 ) is attached to an axle attachment ( 14 ) arranged on the axle ( 9 ).

11 . Stop device according to claim 9 , wherein the stiffness of the stop device ( 1 ) is controlled by the electric motor ( 4 ).

12 . Conveyor system ( 40 ) for conveying objects ( 43 ) on a transport plane ( 42 ), the conveyor system ( 40 ) comprising:

a conveyor ( 41 );

at least one conveyor chain ( 45 ), and

at least one stop device ( 1 ) according to claim 1 .

13 . Conveyor system according to claim 12 , wherein the stop device ( 1 ) is mounted under the transport plane ( 42 ) where the braking surface ( 13 ) of the actuator element ( 3 ) is horizontal when the stop device is in the bypass position ( 22 ).

14 . Conveyor system according to claim 12 , wherein the stop device ( 1 ) is mounted at the side of the conveyor chain ( 47 ) of the conveyor, where the braking surface ( 13 ) of the actuator element ( 3 ) is arranged in a vertical direction.
