First, we measured the total length of the guide required to pull the cement bag is 420 mm. we design the roller guide to guide the arm and lever mechanism. guide design the consideration in the following factor. total stroke divided in the 3 part.
- Total stoke length of the pulling arm.
- The uplift distance of the arm when the initial position of the arm.
- Travel through on cement bag
- Step down movement to lock the cement bag at the end position of the arm.
Roller guide fabricated in the sheet metal . the daimention of guide is Desided bas on the the size of bearing. Its design on SOLIDWORK sheet metal as per design requierments.
Guide divide by basic 3 part. its design and then it converts to the co-ordinate form. fast cam software used to convert the design file to DXF format. MS material sheet 0.8 mm select to cut on the plasma machine.

RESULT AND OBSERVATION :
- Plasma cutting sheet metal does not bend properly. we do not include the all parameter for the as per requirement on the sheet bending.
- we did not include the extra dimension addition at the time of design therefore in at the time of the point of actual bending time it reduces the actual size of the guide.
- And its lot much difficulty in the bending operation.
- After fabrication of the guide, the dimension will not match with the designed so the guide was not used in the pulling mechanism.
