Cup ejecting device for a cup sealing machine

Abstract

A cup sealing machine includes a platform slidable forward and rearward relative to a housing, one or more guide posts dependent downward from the platform, and a cup supporting device slidably engaged on the guide posts and having a barrel slidably engaged through an opening of the platform for supporting a cup to be sealed. The cup supporting device includes one or more wheels for engaging with one or more inclined surfaces of the housing for moving the barrel upward and outward beyond the platform when the platform is moved forward relative to the housing.

I claim:  
     
         1 . A cup sealing machine comprising: 
 a) a housing,    b) a platform slidably supported on said housing, said platform including an opening formed therein,    c) means for moving said platform forward and rearward relative to said housing,    d) at least one guide post secured to said platform and dependent downward from said platform, said at least one guide post being moved in concert with said platform to move forward and rearward relative to said housing,    e) a cup supporting device slidably engaged on said at least one guide post and guided to move upward and downward along said at least one guide post and guided to move upward and downward relative to said platform, said cup supporting device being moved in concert with said at least one guide post and said platform to move forward and rearward relative to said housing, said cup supporting device including a barrel extended therefrom and slidably engaged through said opening of said platform for supporting a cup to be sealed, and    f) means for actuating said barrel to move upward and outward beyond said platform when said platform is moved forward relative to said housing.    
     
     
         2 . The cup sealing machine according to    claim 1    further comprising at least one bar secured to said cup supporting device and slidably engaged on said at least one guide post and guided to move toward and away from said platform.  
     
     
         3 . The cup sealing machine according to    claim 2   , wherein said actuating means includes at least one inclined surface provided in a front portion of said housing, and at least one wheel attached to said at least one bar for engaging with said at least one inclined surface of said housing and for moving said barrel upward and outward beyond said platform when said platform is moved forward relative to said housing.  
     
     
         4 . The cup sealing machine according to    claim 3   , wherein said cup supporting device includes at least one extension extended from said barrel and secured on said at least one bar.  
     
     
         5 . The cup sealing machine according to    claim 1    further comprising means for biasing said barrel downward and away from said platform.  
     
     
         6 . The cup sealing machine according to    claim 5   , wherein said cup supporting device includes at least one extension extended from said barrel and slidably engaged on said at least one guide post, said biasing means includes a spring engaged on said at least one guide post and engaged with said at least one extension of said cup supporting device for biasing said barrel of said cup supporting device downward along said at least one guide post.  
     
     
         7 . The cup sealing machine according to    claim 1   , wherein said actuating means includes at least one inclined surface provided in a front portion of said housing, and at least one wheel attached to said cup supporting device for engaging with said at least one inclined surface of said housing and for moving said barrel of said cup supporting device upward and outward beyond said platform when said platform is moved forward relative to said housing.  
     
     
         8 . The cup sealing machine according to    claim 1   , wherein said housing includes at least one channel formed therein, said platform includes at least one track attached thereto and slidably engaged in said at least one channel of said housing for guiding said platform to move forward and rearward relative to said housing.
