Machine for winding thin metal ribbon continuously on spools

Abstract

A machine for winding thin metal ribbon continuously on spools comprising a fixed entry chute ( 1 ) to receive the ribbon, a pair of support rollers ( 3, 3 ′) with a dancing roller ( 4 ) between them to support and guide the ribbon delivered through said fixed entry chute ( 1 ). A thickness measuring gauge ( 6 ) is provided in the path of the ribbon for continuously monitoring the thickness of the ribbon, a snubber roller assembly ( 30 ) is provided for pressing the ribbon and a brush assembly ( 31 ) is provided for catching the ribbon. A detachable entry chute ( 7 ) and a spool changing platform having a first position (P 1 ), a second position (P 2 ), a third position (P 3 ), and a fourth position (P 4 ) are provided in which the first position (P 1 ) is a ribbon attaching station ( 15 ) with an empty spool on a winding mandril ( 19 ), a second position (P 2 ) is a ribbon winding station ( 16 ) with the winding spool on a winding mandril ( 20 ), the third position (P 3 ) is a station for unloading the wound spool and loading an empty spool, and the fourth position (P 4 ) is a stand-by station ( 17 ) with an empty spool on a winding mandril (21). A hitting rod mechanism ( 9 ) is located close to the ribbon attaching station ( 15 ) to attach the ribbon to the empty spool on the mandril ( 19 ). A ribbon support roller ( 10 ) is located between the winding spool at the ribbon attaching station ( 15 ) and the winding spool at the ribbon winding station ( 16 ) for supporting the ribbon and a delivery chute ( 11 ) is provided for removing cut piece of ribbon after attaching the ribbon on the spool.

1 . A machine for winding thin metal ribbon continuously on spools comprising a fixed entry chute to receive the ribbon, a pair of support rollers with a dancing roller between them to support and guide the ribbon delivered through said fixed entry chute, a thickness measuring gauge in the path of the ribbon for continuously monitoring the thickness of the ribbon, a snubber roller assembly for pressing the ribbon, a brush assembly for catching the ribbon and providing better tension control, a detachable entry chute, a spool changing platform having a first position, a second position, a third position, and a fourth position, the first position being a ribbon attaching station with an empty spool on a winding mandril, a second position being a ribbon winding station with the winding spool on a winding mandril, the third position being a station for unloading the wound spool and loading an empty spool, and the fourth position being a stand-by station with an empty spool on a winding mandril, a hitting rod mechanism located close to the ribbon attaching station to attach the ribbon to the empty spool on the mandril, a ribbon support roller located between the winding spool at the ribbon attaching station and the winding spool at the ribbon winding station for supporting the ribbon, a delivery chute for removing cut piece of ribbon after attaching the ribbon on the spool, a mechanism for wound spool unloading and empty spool loading located at the third position, said spools on mandrils being movable between the four positions on the spool changing platform on a guided path so that an empty spool on the mandril is located at the ribbon attaching station, a winding spool on the winding mandril is located at the ribbon winding station and an empty spool on the mandril is located at the stand by station when the winding is in progress.  
     
     
         2 . The machine as claimed in  claim 1 , wherein said hitting rod mechanism comprises a hitting rod operating lever, an actuating rod for actuating said hitting rod actuating lever and an electromagnet for applying force for hitting.  
     
     
         3 . The machine as claimed in  claim 1 , wherein said spool unloading and spool loading mechanism comprises a base stand, a pusher plate provided with a pushing hydraulic cylinder, a lifting hydraulic cylinder and a platform.  
     
     
         4 . The machine as claimed in  claim 1 , wherein said spool changing platform is provided with movable guides and fixed guides for guiding the motion of the winding mandrils with spools and hydraulic cylinders for pulling and pushing the mandrils to the desired positions.  
     
     
         5 . The machine as claimed in  claim 1 , wherein the said mandrils have collapsible tips for loading and unloading spools easily.  
     
     
         6 . The machine as claimed in  claim 1 , wherein said spool unloading and spool loading mechanism is provided with a turn style having an operating means.  
     
     
         7 . The machine as claimed in  claim 1 , wherein the said fixed entry chute and said delivery chute are provided with suction by means of blowers.  
     
     
         8 . The machine as claimed in  claim 1 , wherein said snubber roller assembly for pressing of the ribbon comprises a holding structure for holding a snubber roller and a hydraulic cylinder for applying force while pressing.  
     
     
         9 . The machine as claimed in  claim 1 , wherein said brush assembly for catching the ribbon comprises a pair of servo motors for driving a pair of brushes in opposite directions, a pair of hydraulic cylinders for the controlled up and down movement of said pair of brushes and applying force to said brushes while catching the ribbon and a base for holding the entire brush assembly.
