Apparatus and method for sorting out coins from bulk metal
View Patent ↗A sorting apparatus for sorting out coins from bulk metal, in particular from non-ferrous bulk metal and/or heavy bulk metal, includes a conveying system, provided with a conveyor belt ( 2 ), for conveying the bulk metal in a conveying direction ( 4 ) to a sorting slot ( 14 ) through which coins can pass and which is defined by a roller ( 10, 11 ), and, on the side opposite the roller ( 10, 11 ), by the conveyor belt ( 2 ), wherein the roller ( 10, 11 ) can be rotated about an axis of rotation ( 6, 7, 30, 31 ) by a drive such that the metal, which cannot be conveyed through the sorting slot ( 14 ) in the conveying direction ( 4 ), can be transported by the roller ( 10, 11 ) in a direction ( 13, 19, 22 ) leading away from the sorting slot ( 14 ) such that the metal can be removed at the side, wherein the sorting apparatus further comprises an apparatus for removing the metal, which is not conveyable through the sorting slot ( 14 ) in the conveying direction ( 4 ), and wherein the apparatus is embodied such that the removal of the metal to the two opposite sides of the conveyor belt takes place in an area in conveying direction ( 14 ) upstream of the roller ( 10, 11 ).
1. A sorting apparatus for sorting out coins from bulk metal, comprising:
conveying means, provided with a conveyor belt ( 2 ), for conveying the bulk metal in a conveying direction ( 4 ) to a sorting slot ( 14 ) through which coins can pass,
wherein the sorting slot ( 14 ) is defined by a roller ( 10 , 11 ), and, on the side opposite the roller ( 10 , 11 ), by the conveyor belt ( 2 ),
wherein the roller ( 10 , 11 ) is rotatable about an axis of rotation ( 6 , 7 , 30 , 31 ) by means of a drive such that the bulk metal, which cannot be conveyed through the sorting slot ( 14 ) in the conveying direction ( 4 ), is transportable by the roller ( 10 , 11 ) in a direction ( 13 , 19 , 22 ) leading away from the sorting slot ( 14 ) such that the bulk metal is removed at the side,
wherein the sorting apparatus further comprises means for removing the bulk metal, which is not conveyable through the sorting slot ( 14 ) in the conveying direction ( 4 ), and
wherein the means for removing the bulk metal are embodied such that the removal of the bulk metal to two opposite sides of the conveyor belt takes place in an area in the conveying direction ( 14 ) upstream of the roller ( 10 , 11 ) wherein the roller ( 10 , 11 ) is contoured such that the bulk metal is removed on the two opposite sides; and
wherein the roller ( 10 , 11 ) encompasses two areas perpendicular to the conveying direction ( 4 ) comprising contour sections inclined outwards relative to the radial plane of the roller ( 10 , 11 ), wherein the contour sections are inclined in different lateral directions for dividing the metal to the two opposite sides.
2. The sorting apparatus according to claim 1 , wherein the contour sections, which are formed by bristles or a solid plastic or metal material, are embodied helically, annularly or partially annularly.
3. The sorting apparatus according to claim 1 , wherein the roller ( 10 , 11 ) is embodied in one piece or comprises two partial rollers ( 28 , 29 ), which are arranged at an angle to one another.
4. A sorting apparatus for sorting out coins from bulk metal, comprising:
conveying means, provided with a conveyor belt ( 2 ), for conveying the bulk metal in a conveying direction ( 4 ) to a sorting slot ( 14 ) through which coins can pass
wherein the sorting slot ( 14 ) is defined by a roller ( 10 , 11 ), and, on the side opposite the roller ( 10 , 11 ), by the conveyor belt ( 2 ),
wherein the roller ( 10 , 11 ) is rotatable about an axis of rotation ( 6 , 7 , 30 , 31 ) by means of a drive such that the bulk metal, which cannot be conveyed through the sorting slot ( 14 ) in the conveying direction ( 4 ), is transportable by the roller ( 10 , 11 ) in a direction ( 13 , 19 , 22 ) leading away from the sorting slot ( 14 ) such that the bulk metal is removed at the side,
wherein the sorting apparatus further comprises means for removing the bulk metal, which is not conveyable through the sorting slot ( 14 ) in the conveying direction ( 4 ), and
wherein the means for removing the bulk metal are embodied such that the removal of the bulk metal to two opposite sides of the conveyor belt takes place in an area in conveying direction ( 14 ) upstream of the roller ( 10 , 11 );
wherein the conveyor belt ( 2 ) is contoured such that removal of the bulk metal to the two opposite sides takes place in an area in conveying direction ( 4 ) upstream of the roller ( 10 , 11 ); and
wherein the conveyor belt ( 2 ) encompasses two areas perpendicular to the conveying direction ( 4 ) comprising contour sections ( 23 ) inclined outwards relative to the conveying direction ( 4 ), wherein the contour sections ( 23 ) are inclined in different lateral directions.
5. The sorting apparatus according to claim 1 , wherein the apparatus includes the roller and at least one additional roller which collectively define a plurality of rollers ( 10 , 11 ), which in each case define a sorting slot ( 14 ) with the conveyor belt ( 2 ), and which are arranged downstream from one another in the conveying direction ( 4 ), wherein the sorting slots ( 14 ), which are spaced apart in the conveying direction ( 4 ), encompass a decreasing slot width.
6. The sorting apparatus according to claim 1 , wherein provision is made on both sides of the conveyor belt ( 2 ) for collecting means and/or transport means for collecting or removing, respectively, removed bulk metal.
