Adhesive tape applying machine for use with a stretch wrapper

Abstract

An adhesive tape applying machine includes two first power sources secured in vertical position, a moving rod joined to output rods of the first power sources at two ends, a second power source connected to the moving rod with an output rod being displaceable in a horizontal direction, a supporting seat joined to the output shaft of the second power source, and an adhesive tape applying mechanism, which is supported on a lower end portion of the supporting seat, and which will apply adhesive tape on an object when it is pressed against and displaced relative to the object; the machine is positioned next to a stretch wrapper such that after the stretch wrapper winds a plastic film around an object, adhesive tape will be stuck on the object and a tail end portion of the plastic film with the adhesive tape applying machine.

1 - 8 . (canceled)  
   
   
       9 . A stretch wrap and adhesive tape system for stretch wrapping a plastic film around an object to be wrapped and securing adhesive tape to said stretch wrapped object comprising: 
 (a) a stretch wrapping mechanism for wrapping said object with said plastic film; and    (b) an adhesive tape application mechanism coupled to said stretch wrapping mechanism and displaced therefrom, said adhesive tape application mechanism being displaceably mounted on an adhesive tape frame including a first power source for displacing said adhesive tape application mechanism in a vertical direction and a second power source for displacing said adhesive tape mechanism in a horizontal direction for contacting said plastic film wrapped object, said adhesive tape application mechanism being displaced in said vertical direction subsequent to said adhesive tape mechanism being displaced into horizontal contact with said wrapped object.    
   
   
       10 . The stretch wrap and adhesive tape applying system as claimed in  claim 9 , wherein the supporting seat is formed with a horizontal extension plate portion at a lower end and a rotationally displaceable disk is supported on the horizontal extension plate portion, said adhesive tape applying mechanism being hung on and pivoted to a shaft portion formed on the rotationally displaceable disk, said adhesive tape applying mechanism having curved slots on two sides of the rotationally displaceable disk, and the horizontal extension plate portion having two stopping protrusions passing through respective ones of the curved slots.  
   
   
       11 . The stretch wrap and adhesive tape applying system as claimed in  claim 9 , which includes: 
 an air cylinder secured to said adhesive tape frame;    a co-moving arm, the co-moving arm being pivoted to a piston rod of the air cylinder at a first end thereof, and pivoted to the frame at a middle portion thereof, the co-moving arm having a second end;    a first smoothing roller supported on the second end of the co-moving arm;    a cutter supported on the frame for cutting an adhesive tape; the first smoothing roller normally touching a blade of the cutter;    a moving arm pivoted to the adhesive tape frame at a first end thereof, the moving arm having a second smoothing roller supported on a second end thereof; and    an elastic element secured to the adhesive tape frame at one end, and connected to a portion of the moving arm that is between the first and the second ends of the moving arm.    
   
   
       12 . The stretch wrap and adhesive tape system as recited in  claim 9  where said adhesive tape frame includes: 
 (a) a pair of vertically directed frame members and a pair of vertical guide rods; and    (b) a vertically displaceable rod coupled to said adhesive tape mechanism for vertically displacing said adhesive tape application mechanism.    
   
   
       13 . The stretch wrap and adhesive tape system as recited in  claim 9  where said adhesive tape frame includes; 
 (a) a horizontally displaceable rod coupled to said adhesive tape application mechanism for horizontally displacing said adhesive tape application mechanism;    (b) a pair of linear rails secured to said horizontally displaceable rod; and    (c) a supporting seat secured to said adhesive tape application mechanism, said supporting seat being displaceable on said linear rails.    
   
   
       14 . A stretch wrap and adhesive tape system for stretch wrapping a plastic film around an object to be wrapped and securing adhesive tape to said stretch wrapped object comprising: 
 (a) a stretch wrapping mechanism for wrapping said object with said plastic film; and    (b) an adhesive tape application mechanism coupled to said stretch wrapping mechanism and displaced therefrom, said adhesive tape application mechanism being displaceably mounted on an adhesive tape frame including a power source for displacing said adhesive tape mechanism in a horizontal direction for contacting said plastic film wrapped object, said adhesive tape application mechanism being engaged subsequent to said adhesive tape mechanism being displaced into horizontal contact with said wrapped object.    
   
   
       15 . The stretch wrap and adhesive tape applying system as claimed in  claim 14 , wherein the supporting seat is formed with a horizontal extension plate portion at a lower end, and a turning disk is supported on the horizontal extension plate portion, and the adhesive tape applying mechanism is hung on and pivoted to a shaft portion formed on the turning disk, and the adhesive tape applying mechanism has curved slots on two sides of the turning disk, and the horizontal extension plate portion has two stopping protrusions passing through respective ones of the curved slots.  
   
   
       16 . The stretch wrap and adhesive tape applying system as recited in  claim 15 , including a plurality of adhesive tape applying mechanisms vertically displaced each from the other for contacting said object at a plurality of discrete vertical heights.  
   
   
       17 . The stretch wrap and adhesive tape applying system as claimed in  claim 14 , wherein the adhesive tape applying system includes: 
 an air cylinder secured on the frame;    a co-moving arm, the co-moving arm being pivoted to a piston rod of the air cylinder at a first end thereof, and pivoted to the frame at a middle portion thereof; the co-moving arm having a second end;    a first smoothing roller supported on the second end of the co-moving arm;    a cutter supported on the frame for cutting an adhesive tape, the first smoothing roller normally touching a blade of the cutter;    a moving arm pivoted to the frame at a first end thereof, the moving arm having a second smoothing roller supported on a second end thereof; and    an elastic element secured to the frame at one end, and connected to a portion of the moving arm that is between the first and the second ends of the moving arm.    
   
   
       18 . The stretch wrap and adhesive tape applying system as recited in  claim 14 , including a plurality of adhesive tape applying mechanisms vertically displaced each from the other for contacting said object at a plurality of discrete vertical heights.
