belt conveyors, automatic drawing and calculation
From the prompt of AutoCAD,
an user executes the respective added "command". Next, the application
reads a data-file and draws automatically the complete conveyor. The drawing
includes the belt configuration, pulleys, bearings, rollers, stringers
and the complete transmission system.
the drawing
The
application draws the components of the conveyor in their precise place,
size and specific layer. The drawing looks like "made by hand" and it is
possible to manage it like any other drawing. Check closer the result at
viewing
the drawing.
accurate drawing
The
system has AutoCAD block-libraries of gear reducers, bearings and couplings
with geometric information according to catalogues of makers (SKF, DODGE
and FLENDER). The most important sizes of these components are reflected
and used for attaching each other. In this way, the drawing produced
by the application is enough accurate that the development of the project
can base on it.
few data for full
drawing
This
is the data-file (ASCII format) that the application requires. Only 33
data (one by row) are needed to produce the full drawing. Basically, the
data are dimensions and specifications; e.g. the radius of the drive pulley
and the modell for the low-speed coupling (from FLENDER brand) are given
as follows:
None "drawing parameter"
(like "insertion points") is necessary to specify. Due to AutoLISP and
AutoCAD are object-oriented applications, the program practically "can
see" the three-dimensional model and places the components in theirs right
place, scale, layer and orientation.
This data-file can be written
"by hand" using a common editor (e.g. WordPAD) or can be generated by another
application e.g. EXCEL.
designing from anywhereThis EXCEL spread-sheet is the complement for the drawing application showed before. Data are introduced into the spreadsheet then the spreadsheet makes calculations according specifications and performances equipment selection. The spread-sheet writes the data-file which is read by the CAD application and converted into drawing .
