An apparatus of mass treatment for dyeing and hdyro-extraction of yarn cheeses for performing sequentially a series of inserting yarn cheeses on spindles, loading on a carrier, dyeing, hydro-extracting, drying and boxing up in cartons, which apparatus comprises a combination of means (a) to (h):
- (a) spindle transferring rail means having thereon mobile trucks comprising an empty spindle-mounting rail portion for mounting empty spindles on mobile trucks and conveying them to a downstream cheese mounting station, a cheese-mounted spindle rail portion for mounting cheeses wound about bobbins on said empty spindles and conveying cheese-mounted spindles to a downstream dyeing treatment station, a dyed cheese-mounted spindle rail portion for conveying as-dyed cheese-mounted spindles on the trucks to a downstream hydro-extracting station, a hydro-extracted cheese-mounted spindle rail portion for conveying hydro-extracted cheese-mounted spindles on the trucks to a downstream drying station, and a return rail portion for returning unoccupied spindles after removal of dried cheeses to the initial empty spindle mounting station, thus linking them to constitute a circulation system;
- (b) cheese inserting and pressing means including a robot disposed alongside of said empty spindle mounting rail portion, said cheese-mounted spindle rail portion comprising extension spindle inserting means, cheese inserting means for feeding a plurality of cheeses from a cheese pool at a time and inserting them on empty spindles conveyed there following the rail until a definite number has been reached, means for inserting spacers and blind bobbins, means for pressing cheeses in the spindle direction, and means for removing said extension spindles after pressing to return them to their initial position and simultaneously locking the top of said spindles with means defining fasteners;
- (c) a dyeing machine for dyeing therein cheese-mounted spindles loaded on a carrier, cheese dyeing means disposed alongside of said cheese-mounted spindle rail portion, said as-dyed cheese-mounted spindle rail portion comprising means for loaded cheese-mounted spindles on a carrier in order to charge them in said dyeing machine, a turntable for charging said cheese-mounted spindles loaded on said carrier into said dyeing machine or restoring as-dyed cheese-mounted spindles discharged out of said dyeing machine from the carrier by reason of a turning motion;
- (d) cheese transfer means disposed adjacent to said turntable for transferring said as-dyed cheese-mounted spindles onto downstream trucks on said dyed cheese-mounted spindle rail portion;
- (e) releasing means for releasing said fasteners, said blind bobbins and said spacers from said dyed cheese-mounted spindles, which release means is disposed alongside of said dyed cheese-mounted spindle rail portion;
- (f) hydro-extracting means disposed alongside of said hydro-extracted cheese-mounted spindle rail portion and adjacent to said releasing means, said hydro-extracting means comprising a hydro-extractor, a hydro-extracting basket, transfer means for transferring dyed cheeses into said hydro-extracting basket to accommodate said cheeses in said hydro-extractor, charging said hydro-extracting basket filled with said cheeses into said hydro-extractor by hanging said cheeses, means for discharging hydro-extracted cheeses together with said hydro-extracting basket at a discharge location and transferring said hydro-extracted cheeses to mobile trucks travelling on said rail;
- (g) drying means comprising cheese transfer means for aligning hydro-extracted cheeses thus discharged and travelled on said hydro-extracted cheese-mounted spindle rail portion in every plural number and a dryer for receiving therein said cheeses;
- (h) delivery means for receiving dried cheeses thereon to convey them to the location of cartons which means is disposed at the outlet of said drier.
