It’s required to remove all problems of pulling the cement bag from the second prototype of the roller guide some geometrical changes done in the third prototype of the roller guide.
In the third prototype there are only two sections included .
- to lift the arm at initial movement thats requierd up movent with some inclination angle
- second portion is a straight guide
RESULT AND OBSEVATION :
- Cement bag pull but total stroke are not used to pulling the bag at the end of the frame.
- Arm roller bearing does not pass over cement bag when some small obstacle are in the path.
- sometime arm rolier guide are stack in the cement bag thats causes tear the bag.
- the area of the tear the bag at the end point where start the pulling.
