<p>Articles, such as components of an injection-molded multi-component product, are repositioned within a space, such as the space between mold parts (14, 16; 44, 46; 74, 76), that is accessible for repositioning only during a series of periods, such as open-mold periods, that are separated by intervals of less accessibility for repositioning, such as closed-mold intervals by (a) moving a first article (18, 48, 90), such as a first component of a first multi-component product (36, 62, 98), from a first position (10', 40', 70') within the space to outside of the space during a first such period; and (b) moving a second identical article (30, 52, 91), such as a first component of a second multi-component product, from outside of the space to a second position (12', 42', 72') within the space during the first such period. Both the movement of the first article and the movement of the second article are by means of a common vehicle (20), such as a common robot arm. In another aspect, an article (18, 48, 90) is repositioned by (a) moving the article from a first position (10', 40', 70') within the space to outside of the space during a first such period; and (b) during a second such period after an interval of less accessibility that is subsequent to the first period, moving the article from outside of the space to a second position (12', 42', 72') within the space. For injection molding with a stack mold, an article (118) is repositioned from a first mold-cavity in a first space in a first portion of the stack mold to a second mold-cavity position in a second space in a second portion of the stack mold by (a) moving the article from a first position (104') to outside of the first and second spaces during a period when the first space is accessible and the second space is inaccessible; and (b) moving the article from outside of the spaces to a second position (110') when the second space is accessible and the first space is inaccessible. <IMAGE> <IMAGE> <IMAGE> <IMAGE> <IMAGE> <IMAGE></p> |
