DEAD FLAT Vacuum conveyor #1

Mountain peaks are beautiful.  

Calm water in a lake settles our mind. 

Printing is done on paper, plastic films, ceramic plate, rubber, and cloth,

only if they are placed flat.  

How can we make them flat?

In addition to gravity, they become flat by vacuum.

The picture below is measurement by laser

on vertical movement of vacuum steel belt surface.

It is controlled within 50 microns.

On Steel Belt No.18 Suction and vacuum conveyance by perforated belts

The last one, very popular perforation is as below:

Suction and vacuum holes are all over the belt.
This works to hold very small parts and very thin objects like paper, plastic sheet and metal sheet.  Flat surface can be realized by suction and vacuum.

Similar pattern is as below.

Locations of these blue parts or cases do not move beyond standing plates.

On Steel Belt No.16 Positioning and takt drive by perforated belts

The second most popular perforation type is as below,
Parts are directly set on square holes in a belt.

On Steel Belt No.15 Positioning and takt drive by perforated belts

We'd like to show some of very popular perforation on belts.
By adding perforation belts can do additional jobs.
The first one is as below.

Jigs are fixed on every pair of holes on a belt.
Those jigs accept parts and these parts receive a certain process, assembly or inspection.  This whole conveyance is done by takt drive, using sprocket pulley pin holes.

On Steel Belt No.14 Welded Endless Belt #4

Above is a figure of stress (S) against the number of cycles to failure (N).

This curve begins to get flat at over one million bendings and becomes flat at over ten million bendings.
Pulley diameter = Belt thickness x 700

Coefficient 700 is set to make the same stress as the one in the chart above so that the belt endures 10 million bendings.

When bendings are not so many,
700 can be 600 or 500
This is to be discussed and adjusted when we decide belt specifications.
