Charging and discharging device for material in the form of a roll and a combination of a printing device and a charging an discharging device

Abstract

A loading and unloading device ( 10 ) for reeled material ( 34 ) is designed in the form of a carriage, which can be moved by a single operator, and has a bearing ( 16 ) for each of the two lateral ends of a reel ( 34 ), it being possible to raise and lower the bearings, which can be locked at least in the raised position.

1 . Loading and unloading device ( 10 ) for reeled material, designed in the form of a carriage which can be moved by a single operator and which has a bearing ( 16 ) for each of the two ends of a reel ( 34 ), it being possible to raise and lower the bearings ( 16 ), which can be locked at least in the raised position.  
     
     
         2 . Loading and unloading device as claimed in  claim 1 , characterised in that the bearings ( 16 ) can be raised and lowered separately from one another.  
     
     
         3 . Loading and unloading device as claimed in  claim 1  or  2 , characterised in that each of the bearings ( 16 ) is operable by means of a lever ( 22 ).  
     
     
         4 . Loading and unloading device as claimed in at least one of the preceding claims, characterised in that the bearings ( 16 ) can additionally be locked in the lowered position.  
     
     
         5 . Loading and unloading device as claimed in at least one of the preceding claims, characterised in that at least one locking element ( 24 ,  28 ) pre-biassed into the closed position is provided, which has an oblique surface ( 30 ) pointing away from the locking position.  
     
     
         6 . Combination of a printer with a loading and unloading device as claimed in at least one of the preceding claims, characterised in that the printer has a safety element ( 44 ) in the region of its reel bearings ( 38 ), which prevents the reel ( 34 ) from falling out and can be moved by the loading and unloading device ( 10 ) during the loading and unloading operation so that a reel ( 34 ) can be introduced and taken out.  
     
     
         7 . Combination of a printer with a loading and unloading device a claimed in  claim 6 , characterised in that the safety element ( 44 ) is pivotable.
