Abstract
The apparatus includes two partially parallel endless rail and trolley systems. The first rail and trolley system guides spacing members so that they approach the moving articles and move along their direction for a distance sufficient to space them. The spacing members are interconnected by articulated connecting arms, which pivot at the spacing members and also at an intermediate pivot point. The intermediate pivot points are guided along the second rail system. Adjustment of the path of the second rail and trolley system relative to the first rail and trolley system where the spacing members operate on the articles permits the adjustment of the spacing operation performed by the spacing members.
Claims13
Apparatus for uniformly spacing from each other articles (11) in a moving line (1) of such articles for facilitating processing of the articles at a processing station, the apparatus comprising:
- a first elongated, endless rail system (15) having a first rail system section adjacent the article line (1) and running along generally parallel to the direction of movement of the line,
- a plurality of article spacing members (16) guided along the first rail system,
- articulated connecting arms (21) interconnecting the article spacing members, the connecting arms pivoting at each spacing member (16) and at an intermediate pivot point (23) between the spacing members,
- a second elongated, endless rail system (30, 30') having a second rail system section adjacent the first rail system section and non-parallel to the first rail system section, the first and second rail systems (15, 30) being adjustable relative to one another in their guidance plane, and including turn-around loop sections at their respective ends;
- pivot guide means (25) for guiding the intermediate pivot points of the articulated connecting arms along the second rail system section;
- drive means (40) for driving the article spacing members (16) along the first rail system section and engaging said article spacing members adjacent one turn-around loop of the first endless rail system;
- and wherein said second rail system (30, 30') comprises a unitary structural element defining an elongated endless pivot guide means closed by end loops, each end loop having a center point (V, 41'), the diameter of the pivot guide means at the region of the end loops of the elongated endless guide means being different, the center point of one of said end loops being pivotably connected to said unitary structure, and fixed with respect to said first rail system (15), the center point of the other of said end loops being movable and shiftable with respect to said first rail system to permit selective positioning of the second rail system with respect to the first rail system.
