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 . An adhesive tape applying machine for use with a stretch wrapper, comprising a frame having two vertical portions; 
 two first power sources held in vertical position next to respective ones of the vertical portions of the frame with output rods thereof;    two secured vertical guide rods;    a moving rod is joined to output rods of the first power sources in a horizontal position; the moving rod being connected to, and up and down displaceable relative to the secured vertical guide rods at two ends thereof;    a second power source connected to the moving rod in a horizontal position such that an output rod thereof is displaceable in a horizontal direction;    two linear rails secured on the moving rod;    a supporting seat; the supporting seat being joined to the output shaft of the second power source; the supporting seat being supported on, and displaceable along the linear rails; and    an adhesive tape applying mechanism supported on a lower end portion of the supporting seat; the adhesive tape applying mechanism being going to apply an adhesive tape on an object when it is pressed against and displaced relative to the object;    the adhesive tape applying machine being positioned next to a stretch wrapper such that after the stretch wrapper winds a plastic film around an object, an adhesive tape will be stuck on the object and a tail end portion of the plastic film to fix the tail end portion of the plastic film in position by means of the adhesive tape applying machine; the adhesive tape applying mechanism being going to smooth a tail end portion of a plastic film when applying an adhesive tape on the tail end portion of the plastic film.    
   
   
       2 . An adhesive tape applying machine for use with a stretch wrapper, comprising 
 a frame having two vertical portions;    two first power sources held in vertical position next to respective ones of the vertical portions of the frame with output rods thereof;    two secured vertical guide rods;    a moving rod is joined to output rods of the first power sources in a horizontal position; the moving rod being connected to, and up and down displaceable relative to the secured vertical guide rods at two ends thereof;    a second power source connected to the moving rod in a horizontal position such that an output rod thereof is displaceable in a horizontal direction;    two linear rails secured on the moving rod;    a supporting seat; the supporting seat being joined to the output shaft of the second power source; the supporting seat being supported on, and displaceable along the linear rails; and    an adhesive tape applying mechanism supported on a lower end portion of the supporting seat; the adhesive tape applying mechanism being going to apply an adhesive tape on an object when the object is pressed against and displaced relative to the adhesive tape applying mechanism;    the adhesive tape applying machine being positioned next to a stretch wrapper such that after the stretch wrapper winds a plastic film around an object, an adhesive tape will be stuck on the object and a tail end portion of the plastic film to fix the tail end portion of the plastic film in position by means of the adhesive tape applying machine; the adhesive tape applying mechanism being going to smooth a tail end portion of a plastic film when applying an adhesive tape on the tail end portion of the plastic film.    
   
   
       3 . The adhesive tape applying machine as claimed in  claim 1 , 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 passed through respective ones of the curved slots.  
   
   
       4 . The adhesive tape applying machine as claimed in  claim 1 , wherein the adhesive tape applying mechanism includes: 
 a frame;    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.    
   
   
       5 . The adhesive tape applying machine as claimed in  claim 1 , wherein a plurality of adhesive tape applying mechanisms of said structure are used instead of single one to suit width of an object to be packaged.  
   
   
       6 . The adhesive tape applying machine as claimed in  claim 2 , 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 passed through respective ones of the curved slots.  
   
   
       7 . The adhesive tape applying machine as claimed in  claim 2 , wherein the adhesive tape applying mechanism includes: 
 a frame;    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.    
   
   
       8 . The adhesive tape applying machine as claimed in  claim 2 , wherein a plurality of adhesive tape applying mechanisms of said structure are used instead of single one to suit width of an object to be packaged.
