Abstract
A conveying device for conveying bulk material, comprising products and product breakage thereof, in a conveying direction has a first conveying element and a second conveying element which is arranged downstream of the first conveying element, with the result that a gap is formed between the first and the second conveying element. A covering element is arranged above the gap. The gap has a first width according to a predefined separating criterion in such a way that the passage of product breakage through the gap is allowed and the passage of products through the gap is prevented.
Claims16
A conveying device for conveying bulk material, comprising a plurality of products and product breakage thereof, in a conveying direction, wherein the conveying device comprises:
- a first conveying element having a first conveying surface on which the bulk material is conveyed in the conveying direction;
- a second conveying element having a second conveying surface on which the bulk material is conveyed further in the conveying direction, wherein the second conveying element is arranged downstream of the first conveying element in the conveying direction;
- and
- a covering element having a covering surface which is arranged substantially parallel to the first conveying surface and to the second conveying surface and faces the first conveying surface and the second conveying surface to form at least one conveying channel for the bulk material between the first conveying surface, the second conveying surface and the covering surface;
- wherein the first conveying element and the second conveying element are arranged spaced apart from one another in the conveying direction such that a gap is formed between the first conveying element and the second conveying element, wherein the covering element is arranged above the gap and above a portion of the first conveying element and a portion of the second conveying element which adjoin the gap;
- wherein, in a first position of the first conveying element and the second conveying element, the gap has, in the conveying direction, a first width according to a predefined separating criterion which allows passage of product breakage through the gap, but prevents passage of products through the gap;
- and
- wherein the conveying device further comprises a plurality of guide elements which extend over the gap in the conveying direction, are arranged next to one another in a direction transversely to the conveying direction and laterally delimit a plurality of conveying channels for the bulk material transversely to the conveying direction, wherein the covering element upwardly delimits the plurality of conveying channels, and wherein the first conveying surface and the second conveying surface downwardly delimit the plurality of conveying channels in portions of the first and second conveying elements which adjoin the gap.
A blister machine having:
- a product store for receiving bulk material comprising a plurality of products and product breakage thereof,
- a conveying device for separating product breakage and conveying the products in a conveying direction, wherein the conveying device comprises:
- a first conveying element having a first conveying surface on which the bulk material is conveyed in the conveying direction;
- a second conveying element having a second conveying surface on which the bulk material is conveyed further in the conveying direction, wherein the second conveying element is arranged downstream of the first conveying element in the conveying direction;
- and
- a covering element having a covering surface which is arranged substantially parallel to the first conveying surface and to the second conveying surface and faces the first conveying surface and the second conveying surface to form at least one conveying channel for the bulk material between the first conveying surface, the second conveying surface and the covering surface;
- wherein the first conveying element and the second conveying element are arranged spaced apart from one another in the conveying direction such that a gap is formed between the first conveying element and the second conveying element, wherein the covering element is arranged above the gap and above a portion of the first conveying element and a portion of the second conveying element which adjoin the gap;
- wherein, in a first position of the first conveying element and the second conveying element, the gap has, in the conveying direction, a first width according to a predefined separating criterion which allows passage of product breakage through the gap, but prevents passage of products through the gap,
- and a filling station for filling the products into blisters, wherein the product store is configured to dispense the bulk material to the conveying device and the conveying device is configured to convey the products to the filling station.
A method for conveying and sorting bulk material comprising a plurality of products and product breakage thereof, said method carried out in a blister machine, the blister machine having a product store for receiving bulk material comprising a plurality of products and product breakage thereof, a conveying device for separating product breakage and conveying the products in the conveying direction, and a filling station for filling the products into blisters, wherein the product store is configured to dispense the bulk material to the conveying device and the conveying device is configured to convey the products to the filling station, wherein the method comprises the steps of:
- conveying the bulk material on a first conveying surface of the conveying device of the blister machine in a conveying direction to a gap which has, in the conveying direction, a first width according to a predefined separating criterion such that product breakage passes through the gap and passage of products through the gap is prevented;
- moving the products in the conveying direction beyond the gap onto a second conveying surface of the conveying device of the blister machine and separating product breakage through the gap;
- and
- conveying the products on the second conveying surface further in the conveying direction.
A conveying device for conveying bulk material, comprising a plurality of products and product breakage thereof, in a conveying direction, wherein the conveying device comprises:
- a conveying element having a first conveying surface on which the bulk material is conveyed in the conveying direction;
- a second conveying element having a second conveying surface on which the bulk material is conveyed further in the conveying direction, wherein the second conveying element is arranged downstream of the first conveying element in the conveying direction;
- and
- a covering element having a covering surface which is arranged substantially parallel to the first conveying surface and to the second conveying surface and faces the first conveying surface and the second conveying surface to form at least one conveying channel for the bulk material between the first conveying surface, the second conveying surface and the covering surface;
- wherein the first conveying element and the second conveying element are arranged spaced apart from one another in the conveying direction such that a gap is formed between the first conveying element and the second conveying element, wherein the covering element is arranged above the gap and above a portion of the first conveying element and a portion of the second conveying element which adjoin the gap;
- wherein, in a first position of the first conveying element and the second conveying element, the gap has, in the conveying direction, a first width according to a predefined separating criterion which allows the passage of product breakage through the gap, but prevents the passage of products through the gap;
- wherein the conveying device comprises at least one sensor for recognizing jams of bulk material in the gap.
