Abstract: An assembly and method for moving bulk items from a first location to a second location is disclosed. The items are moved from the first location to the second location through a pick-up head. Vacuum pressure is supplied to the head to pick-up an item at the first location and carry the item to the second location. A detector is located between the first location and the second location to detect if an item has been picked up by the head. If no item is detected, the head is closed to the vacuum pressure through a control mechanism or closure element.
