Automatic positioning system for filling device of filling machine

Abstract

An automatic positioning system is provided for a filling device of a filling machine, wherein the filling device has a plurality of filling head mounted on a support to fill a plurality of containers positioned on filling positions with a material. The automatic positioning system comprises a first automatic positioning system for controlling the support to shift along a vertical linear route to and fro and positioning the support at a desired position in the linear route. The first automatic positioning system further controls a rising speed of the support. The automatic positioning system also comprises a second automatic positioning system for controlling a container-supporting unit to provide the containers with a supporting force.

       7 . The automatic positioning system of  claim 6 , wherein the transmission of the first automatic positioning system is a stepping motor or a servo motor. 
   
   
       8 . The automatic positioning system of  claim 4 , wherein the first automatic positioning system is, a combination of a normal motor and an optical linear scale, a magnetic scale, or a limit switch, or a combination of a motor and a decoder. 
   
   
       9 . The automatic positioning system of  claim 4 , wherein the first automatic positioning system is a linear motor. 
   
   
       10 . The automatic positioning system of  claim 4 , further comprising a second automatic positioning system, which is deposited on the second brace set while the brace set is fixed to a fixing component of the filling machine, a container-supporting unit, which is fixed to the second moving unit, a second automatic positioning system, which controls the second moving unit to shift along the second brace set and positions the second brace set at a desire position wherein the desired position includes an initial position where the container-supporting unit evades the container and a supporting position where the container-supporting unit provides a supporting force to the container. 
   
   
       11 . The automatic positioning system of  claim 10 , wherein the second automatic positioning system comprises a transmission and a screw rotated by the transmission wherein the second moving unit is assembled to the screw and the transmission is deposited at the top of the second brace set while the screw is fastened to the fixing component of the filling machine in a pivotable way. 
   
   
       12 . The automatic positioning system of  claim 11 , wherein the transmission of the second automatic positioning system is a stepping motor or a servo motor. 
   
   
       13 . The automatic positioning system of  claim 10 , wherein the second automatic positioning system is, a combination of a normal motor and an optical linear scale, magnetic scale, or a limit switch, or a combination of a motor and a decoder. 
   
   
       14 . The automatic positioning system of  claim 10 , wherein the second automatic positioning system is a linear motor. 
   
   
       15 . An automatic positioning system for a filling device of a filling machine, wherein the filling device has a plurality of filling head mounted on a support to fill a plurality of containers positioned on filling positions with a material, comprising:
