Abstract:
A conveying method for intermittently rotating a pair of support conveyers, consisting of a first support conveyer and a second support conveyer, for 180 degrees each time along a circular orbit around a horizontal transverse main shaft, the first and second support conveyers being symmetrically disposed 180 degrees apart with respect to the horizontal main shaft, comprising the steps of:conveying a tray containing a plurality of packaged articles onto the first support conveyer from outside the circular orbit when the first support conveyer is at a lower position of the orbit and the second support conveyer is at an upper position of the orbit; pressing the packaged articles into the tray by means of a support plate descending from an area above the first support conveyer; moving said tray and said first support conveyer for 180 degrees along the circular orbit to the upper position in which the tray is upside-down while keeping the packaged articles pressed into the tray; drawing down the packaged articles on the support plate from the tray while leaving the tray behind at the upper position; horizontally pushing the tray that was left behind at the upper position onto a downwardly slanting guide for discharge by gravity along the guide to the outside of the circular orbit; moving the first support conveyer 180 degrees along the circular orbit from the upper position back to the lower position while causing the support plate to press the packaged articles to the first support conveyer to return the packaged articles to the lower position; and conveying the packaged articles to the outside of the circular orbit by the action of the first support conveyer; wherein the second support conveyer shifts 180 degrees to the lower position when the first support conveyer shifts 180 degrees to the upper position and two batches of the packaged articles are conveyed every time the first and second support conveyers rotate one round about the main shaft.
