Abstract

Strips are fed sequentially from hopper 10 by pulling the bottom strip onto rotating feed wheel 11 via vacuum slots 12 adjacent to such wheel. Strips are received onto the top of the stack in hopper 10. In feeding strips, the bottom strips are lubricated by air provided from angled ports 13. The latter blow air at the front edge of the strip pack to aid in front edge separation to permit bottom strip feeding. Windows 22 exhaust the blowing air. The strip is fed out to a belt conveyence or other devices not shown. The strip is transported and returned by devices, not shown, to the upper portion of hopper 10.

Strip Sequential Transport Stacker

Strips are fed sequentially from hopper 10 by pulling the bottom strip onto rotating feed wheel 11 via vacuum slots 12 adjacent to such wheel. Strips are received onto the top of the stack in hopper 10. In feeding strips, the bottom strips are lubricated by air provided from angled ports 13. The latter blow air at the front edge of the strip pack to aid in front edge separation to permit bottom strip feeding. Windows 22 exhaust the blowing air. The strip is fed out to a belt conveyence or other devices not shown. The strip is transported and returned by devices, not shown, to the upper portion of hopper 10.

As the strip is returned, it is cupped, decelerated, and stacked at the top of the strip pack. Stacker wheel 16, which rotates at stacking speed, raises a strip above the level of beveled edge guides 17 to form the strip in a cup shape. The cupping action causes frictional engagement of the strip with edge guides 17 and the periphery of wheel 16 to cause strip deceleration. Air is supplied through tube L under the strip at wheel 16. This causes an air cushion to build up between the strip being stacked and the strip pack to prevent strip contact and to make stacking speed more uniform. Air is supplied above the stacking strip through tube M. During stacking, when the strip is cupped, the air causes the strip to more positively engage wheel 16 to aid deceleration.

When the strip leaves wheel 16, it becomes uncupped, and the sp...
