Winding machine

Abstract

A winding machine includes a frame with a main axis fixed on. A winding tray is engaged on the main axis and defines long slots. Winding spindles pass through the long slots respectively and stretch forward. An unloading mechanism includes a basic tray and a sub-tray mounted on the main axis. The basic tray defines through-holes and guiding holes. The unloading mechanism further includes unloading units, and each unloading unit has a panel member pivotally connected to the basic tray. The panel member defines an arc track and integrates with a connecting member connected to the basic tray by helical springs and engaging with the winding spindle. A sliding pillar slidably located in the front of the basic tray projects forward to form a supporting element configuring a first idler wheel. A pushing block is moveably received in the through-hole. A front end thereof protrudes out of the through-hole and defines an inclined guide surface and a back end extends to be fixed on the sub-tray. A driven mechanism is configured between the frame and the sub-tray for providing a force to the sub-tray.

1 . A winding machine, comprising:
 a frame;   a main axis, fixed on the frame and horizontally extending forward;   a winding tray, engaged on a front end of the main axis and defining long slots therethrough;   winding spindles, passing through the long slots of the winding tray respectively and stretching forward; and   an unloading mechanism, having
 a basic tray, mounted on the main axis and between the winding tray and the frame, defining through-holes and guiding holes, each through-hole being correspondingly adjacent to one of the guiding holes, 
 a sub-tray, mounted on the main axis and between the basic tray and the frame, 
 unloading units, each of the unloading units having
 a panel member, pivotally connected to the front of the basic tray, defining an arc track thereon, each panel member integrating with a connecting member which is connected to the basic tray by helical springs, the connecting member engaging with the winding spindle, 
 a sliding pillar, parallel and slidably located in front of the basic tray, the sliding pillar projecting forward to form a supporting element, the head of the supporting element configuring a first idler wheel sustaining an end of the arc track of the panel member, an end of the sliding pillar configuring a second idler wheel, 
 a pushing block, moveably received in the through-hole of the basic tray, a front end of the pushing block protruding out of the through-hole and defining an inclined guide surface thereon to hold the second idler wheel of the sliding pillar, a back end of the pushing block extending to be fixed on the sub-tray, 
 a guide pillar, moveably received in the guiding hole, and one end of the guide pillar fixed on the sub-tray and 
 a reinstating spring, encircling the guide pillar, one end of the reinstating spring against the basic tray, and the other end of the reinstating spring against the sub-tray, and 
 
   a driven mechanism, configured between the frame and the sub-tray for providing a force to the sub-tray.   
   
   
       2 . The winding machine as claimed in  claim 1 , wherein the other end of the guide pillar couples with a screw cap before the basic tray. 
   
   
       3 . The winding machine as claimed in  claim 1 , wherein the unloading unit further comprises a first receiving element and a second receiving element protruding forward from the basic tray, bilateral sides of the first receiving element define a long groove, a receiving hole is defined in the center of the first receiving element and passes through the first receiving element, the receiving hole communicates with the grooves, the sliding pillar passes through and is slidably received in the receiving hole of the first receiving element and the second receiving element. 
   
   
       4 . The winding machine as claimed in  claim 3 , wherein the unloading unit further comprises two pairs of limit screws provided to locate a pair of first helical springs between the first receiving element and the second receiving element, one pair of the limit screws are respectively inserted in the grooves and further inserted into bilateral sides of the sliding pillar to locate ends of the first helical springs on the bilateral sides of the sliding pillar, the other pair of the limit screws are inserted in bilateral sides of the second receiving element to locate the other ends of the first helical springs on the bilateral sides of the second receiving element. 
   
   
       5 . The winding machine as claimed in  claim 3 , wherein the first receiving element receives a pair of pads in a row in a front surface thereof to sustain the connecting member. 
   
   
       6 . The winding machine as claimed in  claim 3 , wherein the front surface of the first receiving element defines a projection to pivotally connect with the panel member through a shaft. 
   
   
       7 . The winding machine as claimed in  claim 1 , wherein the connecting member has a front surface integrating with a retaining member where the winding spindle is fixed. 
   
   
       8 . The winding machine as claimed in  claim 1 , wherein the driven mechanism includes two cylinders distributing symmetrically around the main axis, an impelling arm is set on a piston of the cylinder, the front surfaces of the impelling arms dispose an impelling tray locating around the main axis and behind the sub-tray.
