Abstract

1468605 Concrete casting plant ETABS MINATO SA 9 May 1974 [21 March 1974 (2)] 20569/74 Heading B5A A plant for casting concrete articles, e.g. slabs, poggings, kerbstones, setts comprises two moulding stations 3, 4 fed alternately with concrete from a metering hopper 1<SP>1</SP> by a drawer 2 operated by a double-acting jack or a rack and pinion, a load handling plant, stoving chambers 21-23 and a station 31, 32 for sorting and delivering the articles. The moulding stations are fed alternately with boards 6 from associated stacks of boards by one or more jacks 91. Each board forms the base of the mould for the respective article and serves as a pallet for transferring the article to the various chambers and delivery stations. Following moulding by tamping and vibrating at the moulding stations, mould parts 5 are raised by jacks to allow the articles to be removed from the moulding stations by an incoming board, a ram 150 or rollers and transferred to an elevator 41 on a conveyer 411 where they are stacked and removed a stack at a time by a multi-fork truck 43 (see also Figs. 4, 5, not shown) which runs along rails 431 to a transfer carriage 44 (see also Fig. 5) which conveys the truck 43 along rails 441 to a first stoving chamber to deposit its load, to a second stoving chamber to pick up a load which has been stoved and to tracks 432 so that the truck 43 can pass therealong to an elevator 42 which delivers the completed articles to a take-off conveyer 421 and to the station 31 for delivering the articles and returning the base boards 6 to the stacks feeding the moulding stations. The third stoving chamber cures a batch of stacks of articles whilst the other two chambers are being filled and emptied.
