Method and apparatus for processing strip end

Abstract

The invention relates to a device for processing an end of a strip, in particular a metal strip (2), wound up into a coil (1), in particular for sampling and/or for inspection of the strip, with a winding device for unwinding the end of the strip. This device is characterized in that the winding device is formed as a coiler (9) with one or more rotatable coiler drums (10) for receiving the coil (1) and in that the coiler (9) is arranged on a transporting system (11), with which the coiler (9), and the coil (1) arranged on it, can be moved between various processing stations (3, 5, 6).

1 . An apparatus for processing an end of a strip, wound into a coil the apparatus comprising a coiler for unwinding the end of the strip, wherein
 the coiler has a reel with one or more rotating mandrels for receiving the coil and   the reel is on a conveyor with which the reel and the coil attached thereto can be moved between the individual processing stations.   
     
     
         2 . The apparatus according to  claim 1 , further comprising:
 a tape stripper,   a processing device , downstream from the tape stripper, and   a strapping tool downstream from the processing device between which the reel can be displaced along a conveying direction.   
     
     
         3 . The apparatus according to  claim 1 , wherein the conveyor has a trolley that can be displaced on rails preferably displaced a conveying direction parallel to the coil axis. 
     
     
         4 . The apparatus according to  claim 1 , wherein the reel is vertically shiftable against or on the conveyor. 
     
     
         5 . The apparatus according to  claim 3 , wherein the trolley has a chassis movable along rails and a support frame attached to the chassis in a height-adjustable manner and on which the reel is mounted. 
     
     
         6 . The apparatus according to  claim 5 , wherein the support frame is pivotal on the chassis about an axis that is oriented parallel to the coil axis. 
     
     
         7 . The apparatus according to  claim 6 , further comprising:
 a first pusher with at least one adjustable pressure element on the conveyor on the support frame thereof.   
     
     
         8 . The apparatus according to  claim 7 , further comprising:
 a second pusher with at least one adjustable pressure element on the conveyor on the support frame thereof, and offset angularly from the pressure element of the first pusher on the coil outer surface by an angle of from 90° to 180°.   
     
     
         9 . The apparatus according to  claim 8 , further comprising:
 an additional stationary pusher with an adjustable pressing element near the processing device so as to be offset from the pressure elements of the first pusher or of the second pusher relative to the coil outer surface.   
     
     
         10 . The apparatus according to  claim 1 , wherein the processing device has a lower strip guide or an upper strip guide that is height-adjustable or pivotable. 
     
     
         11 . A method of processing an end of a strip wound into a coil, with an apparatus according to  claim 1 , wherein the coil is received by the reel and moved by the conveyor between different processing stations. 
     
     
         12 . The method according to  claim 11 , wherein the coil is taken off the reel and the tape is first removed by a tape stripper, the coil is then moved into the vicinity of the sampler where the end of the strip is unwound with the reel and a portion of the end of the strip is separated as a specimen, and, thereafter, the end of the strip is rewound with the reel and the coil is transported to the vicinity of a strapping tool and strapped there with tape. 
     
     
         13 . The method according to  claim 12 , wherein the end of the strip is first fixed to the coil with a pusher and then the tape is removed, that the coil is then transported with the pusher fixing the end of the strip to the vicinity of the processing device, for example the sampler, and that the end of the strip is unwound there with the reel. 
     
     
         14 . The method according to  claim 13 , wherein the end of the strip is fixed by the additional stationary pusher and subsequently released with the first or second pusher, and the end of the strip is then unwound.
