Object feeding system

Abstract

The present invention provides an object-feeding system. The feeding system includes an object feeder and a pickup roller. The object feeder includes an object separating ramp and a tray part. The object separating ramp is placed along an object feeding direction. The tray part is for loading at least an object to be fed, and the tray part includes a main body and a protruding portion sticking out from the main body and connected to the object separating ramp, wherein the protruding portion and the main body constitute a hollow part. The pickup roller is for feeding the object by rolling, wherein the hollow and the pickup roller separately locate two sides of the object and the pickup roller locates the hollow place above.

1 . An object-feeding system, comprising:
 an object feeder, comprising:
 an object separating ramp, placed along an object feeding direction; and 
 a tray part, for loading at least an object to be fed, including:
 a main body; and 
 a protruding portion, sticking out the main body and connected to the object separating ramp, wherein the protruding portion and the main body form a hollow part; and 
 
   a pickup roller, for feeding the object by rolling, wherein the hollow part and the pickup roller are respectively located at two sides of the object and the pickup roller is located above the hollow part.   
     
     
         2 . The object-feeding system of  claim 1 , wherein the hollow part is located on the protruding part, where the surface facing the object to be fed of the main body is higher than the surface facing the object to be fed of the protruding part. 
     
     
         3 . The object-feeding system of  claim 1 , wherein the hollow part is located on the main body, where the surface facing the object to be fed of the main body is lower than the surface facing the object to be fed of the protruding part. 
     
     
         4 . The object-feeding system of  claim 1 , wherein the hollow part is located between the protruding part and the main body. 
     
     
         5 . The object-feeding system of  claim 1 , further comprising an object isolating device revolvably connected to the protruding part, wherein the object isolating device is located at a first location to isolate the object to be loaded by the tray part and the object separating ramp if the object-feeding system is in a non-feeding situation, and the object isolating device revolves from the first location to a second location such that the object to be fed can be fed if the object-feeding system is in a feeding situation. 
     
     
         6 . The object-feeding system of  claim 1 , wherein the pickup roller has a normal force self-compensation structure. 
     
     
         7 . An object-feeding system, comprising:
 an object feeder, comprising:
 an object separating ramp, placed along an object feeding direction; and 
 a tray part, for loading at least an object to be fed, including:
 a main body; and 
 a protruding portion, sticking out from the main body and connected to the object separating ramp, wherein the protruding portion and the main body form a hollow part; and 
 
 an elastic supporting device, located above the hollow part; and 
   a pickup roller, for feeding the object by rolling, wherein the hollow part and the pickup roller are respectively located at two sides of the object and the pickup roller is located above the hollow part.   
     
     
         8 . The object-feeding system of  claim 7 , wherein the hollow part is located on the protruding part, where the surface facing the object to be fed of the main body is higher than the surface facing the object to be fed of the protruding part. 
     
     
         9 . The object-feeding system of  claim 7 , wherein the hollow part is located on the main body, where the surface facing the object to be fed of the main body is lower than the surface facing the object to be fed of the protruding part. 
     
     
         10 . The object-feeding system of  claim 7 , wherein the hollow part is located between the protruding part and the main body. 
     
     
         11 . The object-feeding system of  claim 7 , further comprising an object isolating device, revolvably connected to the protruding part, wherein the object isolating device is located at a first location to isolate the object to be loaded by the tray part and the object separating ramp if the object-feeding system is in a non-feeding situation, and the object isolating device revolves from the first location to a second location such that the object to be fed can be fed if the object-feeding system is in a feeding situation. 
     
     
         12 . The object-feeding system of  claim 7 , wherein the elastic supporting device comprises:
 a supporting board; and   an elastic device, with two ends respectively connected to the supporting board and the protruding part to provide an elastic force to the supporting board.   
     
     
         13 . The object-feeding system of  claim 12 , wherein the elastic device is a spring. 
     
     
         14 . The object-feeding system of  claim 7 , wherein the pickup roller has a normal force self-compensation structure. 
     
     
         15 . An object-feeding system, comprising:
 an object feeder, comprising:   an object separating ramp, placed along an object feeding direction; and   a tray part, comprising:
 a first tray, connected to the object separating ramp; and 
 a second tray, located on the first tray, for loading at least one object to be fed, wherein the second tray is made of elastic material; and 
   a pickup roller, for feeding the object by rolling.   
     
     
         16 . The object-feeding system of  claim 15 , further comprising an object isolating device revolvably connected to the protruding part, wherein the object isolating device is located at a first location to isolate the object to be loaded by the tray part and the object separating ramp if the object-feeding system is in a non-feeding situation, and the object isolating device revolves from the first location to a second location such that the object to be fed can be fed if the object-feeding system is in a feeding situation. 
     
     
         17 . The object-feeding system of  claim 15 , wherein the pickup roller has a normal force self-compensation structure.
