TRAY TRANSFER APPARATUS AND SIDE PUSH APPARATUS EMPLOYED IN SAME

摘要

The invention relates to a tray transfer apparatus, comprising an object to be transferred, a first conveyor rail, first and second guide rails, a side push unit and a second conveyor rail. The first conveyor rail supports the object to the transferred, and conveys the object to a first work position. The first and second guide rails are arranged to correspond to the first and second sides of the object, respectively, and guide the first and second sides of the object, respectively, with a predetermined spacing between the object and the guide rails. The side push unit includes a push arm which pushes the second side of the object in a first direction toward the first side of the object such that the object is aligned along the first side thereof by the first guide rail after the object is transferred to the first work position, and which returns in a second direction from the first side toward the second side of the object. The second transfer rail supports the object and transfers the object to a second work position after the second side of the object is pushed by the push arm. Thus, the object can be aligned in a precise manner.
