Upstacking Pulleys for Lids
Bunting® Magnetics Co. custom manufactures different sizes of adjustable Magnetic Upstacking Pulleys to be used on can lids, jar lids, oil filter tapping plates and other uniform lid and filter type ferrous metal items. These are usually 3 or 4 pole magnetic assemblies designed to snap in – stabilize – control – feed – force lids into sleeves or feeding machines. The diameters are also designed relative to the size of the lid.
The lids are usually fed into the Magnetic Upstacker Pulley by a high speed belted conveyor as seen the in the video below. The magnetic field loops suck the lids into magnetic adjustable flanges to secure the lids perpendicular to the pulley. The magnetic field is transmitted into the lids causing similar pole repelling polarity to keep the lids fanned parallel to each other as they rotate around the pulley. As the magnetic Upstacking Pulley rotates, the magnetic force on the lids forces the lids into a track or sleeve.
Magnetic Upstacker Pulleys are usually independently driven with VFD variable speed drive motors to adjust the Magnetic Upstacker Pulley rotation speeds to the line speeds. Contact Bunting® Magnetics Co. for additional information and pricing.
