<div dir="ltr">Hi Robin, I worked on Apple and Kiwifruit singulators a few decades ago.: Below: a good description from Lynx fruit graders.. Essentially we used uphill V shape conveyors. They needed quite a bit of tuning but then worked well for years, no matter what the fruit size was. We were aiming for about 40 apples per second in eight lanes. It was quite exciting when it failed. <div>Guy</div><div><div><p style="color:rgb(27,35,39);font-family:'Lucida Grande','Lucida Sans Unicode',Arial,Helvetica,sans-serif;font-size:12px"><i><strong>2. Singulator</strong>.</i></p><p style="color:rgb(27,35,39);font-family:'Lucida Grande','Lucida Sans Unicode',Arial,Helvetica,sans-serif;font-size:12px"><i>The singulator comprises “v” shaped rubber rollers on an incline to achieve a high level of singulation (80% average) through the unique design of the roller, and the rotation of the rollers which is controlled by the Lynx operating system. This rotates the fruit as it moves up the incline section in either the forward or reverse direction depending on the product type and size.</i></p><div class="gmail_extra"><br><div class="gmail_quote">On Sat, May 2, 2015 at 11:00 PM, <span dir="ltr"><<a href="mailto:chchrobotics-request@lists.linuxnut.co.nz" target="_blank">chchrobotics-request@lists.linuxnut.co.nz</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">Send Chchrobotics mailing list submissions to<br>
