PALLET FOR STEPWISE STACKING WORKS SUCH AS CERAMIC GREEN SHEET, GREEN SHEET LAMINATE PRESS BONDING MATERIAL, PRINTED CIRCUIT BOARD OR THE LIKE

摘要

PROBLEM TO BE SOLVED: To provide a convenient pallet for stepwise stacking works (ceramic green sheets, green sheet laminate press bonding materials, printed circuit boards or the like) without necessity of using a special purpose unit (e.g., a suction plate to be introduced into or retracted from above an indexing table and reversed) or artificially reversing the work one by one in the case of reversing the work. SOLUTION: Recesses (annular recesses) 4 are formed at one of upper and lower ends of edge frames 1 of pallet elements 2 formed by providing work mounting surfaces 11 at halfway height sites of the frames 1, and protrusions (annular protrusions) 3 are formed at the other. Necessary pallet elements 2 of a necessary number are stackably constituted by detachable and attachable engagements of the recesses 4 with the protrusions 3. In this case, the frames 1 are formed slightly larger than the works W in a planely seen shape so as to allow movements of the works W in a vertical direction in spaces 5 between the pallet elements in the case of reversing in a stacked state.
