Example program for a two-axis loading machine

What this chapter contains

This chapter presents an example sequence program which controls a loading

machine with two axes.

Description of the machine

The machine loads boxes. The first axis loads ten items to each box and the second

axis moves the filled boxes forward on a conveyor.

Description of the program

Loading sequence

The first axis toggles between positions 50 and 0. Every time when it does a forthward

movement, it pushes one item to a box. Thereafter, the axis moves backwards. When

the first axis has finished one forward-backward movement, the second axis makes

a movement of distance 10, and the next empty slot in the box comes in front of the

machine's loading point. This way, the machine fills the 10 slots of the box.

When the loading sequence has repeated 10 times, the box is full. The program, then,

moves the box a distance of 1000. This is the distance between the boxes. After this,

the sequence starts again and fills the next box.
