Method and conveying device for conveying bulk material

Abstract

In the method of the invention for conveying bulk goods by means of a conveying device comprising a conveying channel and at least two conveying elements ( 266, 269 ) arranged loosely in the conveying channel, the conveying elements are mechanically driven in the conveying direction in a first section of the conveying channel, before bulk goods are fed into the conveying channel in a second section of the conveying channel. The bulk goods are conveyed by movement of the conveying elements along the conveying direction in a third section of the conveying channel, wherein in this third section of the conveying channel the first conveying element ( 269 ) is pressed by the second conveying element ( 266 ) and/or the bulk goods through the conveying channel in the conveying direction. The invention also comprises a conveying device for carrying out this method.

1 . A method for conveying bulk goods by means of a conveying device comprising a conveying channel and at least two conveying elements ( 266 ,  269 ) loosely arranged in the conveying channel, the method comprising the following steps:
 mechanically driving the conveying elements ( 266 ,  269 ) in the conveying direction in a first section of the conveying channel,   feeding bulk goods into the conveying channel in a second section of the conveying channel,   conveying the bulk goods by moving the conveying elements ( 266 ,  269 ) along the conveying direction in a third section of the conveying channel,   wherein in the third section of the conveying channel, the first conveying element ( 269 ) is pressed by the second conveying element ( 266 ) and/or the bulk goods through the conveying channel in the conveying direction.   
     
     
         2 . The method according to  claim 1 , wherein during mechanical driving, a conveying element ( 266 ) is in direct contact with at least one drive element ( 263 ) via an opening ( 265 ) in the first section of the conveying channel. 
     
     
         3 . The method according to  claim 2 , wherein per length of a conveying element ( 266 ) in the conveying direction, at least two drive elements ( 263 ) are provided via the opening ( 265 ) in the first section of the conveying channel. 
     
     
         4 . The method according to  claim 1 , wherein the longitudinal axis of at least one conveying element ( 266 ) is aligned substantially parallel to the conveying direction in the first section of the conveying channel. 
     
     
         5 . The method according to  claim 4 , wherein the conveying elements ( 266 ) are driven by direct contact with at least one conveying element in the first section of the conveying channel. 
     
     
         6 . The method according to  claim 4 , wherein the conveying elements in the transition area (ÜB) between the first and the second section of the conveying channel are driven by direct contact with the rear or the front disk ( 267 ,  268 ) of the conveying element in the conveying direction. 
     
     
         7 . A conveying device for conveying bulk goods comprising a conveying channel and at least two conveying elements ( 266 ,  269 ),
 wherein the conveying device comprises:   a mechanical drive means ( 261 ) for driving the conveying elements ( 266 ,  269 ) in the conveying direction in a first section of the conveying channel, wherein the conveying elements are loosely arranged in the conveying channel,   wherein the conveying channel comprises a feeding opening for feeding bulk goods in a second section of the conveying channel, and   wherein the conveying device is configured such that in a third section of the conveying channel the first conveying element ( 269 ) is pressed by the second conveying element ( 266 ) and/or bulk goods through the conveying channel in the conveying direction.   
     
     
         8 . The conveying device according to  claim 7 , wherein the conveying channel comprises an opening ( 265 ) in the first section through which the drive means ( 261 ) pushes the conveying elements ( 266 ) via direct contact therewith through the first section of the conveying channel in the conveying direction. 
     
     
         9 . The conveying device according to  claim 7 , wherein the mechanical drive means ( 261 ) comprises at least two drive elements ( 263 ), wherein the distance between the drive elements in the conveying direction corresponds to half the length of a conveying element. 
     
     
         10 . The conveying device according to  claim 7 , wherein drive elements ( 263 ) of the mechanical drive means are bolts and/or hydraulic elements and/or pneumatic elements. 
     
     
         11 . The conveying device according to  claim 7 , wherein the conveying channel has a non-rectangular feeding opening for bulk goods in the second section. 
     
     
         12 . The conveying device according to  claim 7 , wherein the conveying channel has an opening whose width at the rearmost point of the opening in the conveying direction is smaller than at another point of the opening. 
     
     
         13 . The conveying device according to  claim 12 , wherein the opening is a drive opening and/or the feeding opening and/or an outlet opening and/or a viewing window and/or an insertion opening for conveying elements. 
     
     
         14 . The conveying device according to  claim 7 , wherein the conveying device, in particular the conveying channel, is lockable. 
     
     
         15 . The conveying device according to  claim 7 , wherein at least one of the conveying elements is provided with a label for automatic identification and/or localization and the conveying device comprises a reader for reading out the label.
