Abstract
A plant for automatically supplying hanks carried on sticks to a squeezing unit or squeezer for hank squeezing, for removing squeezed hanks from the squeezer, for transfer of hanks to a movement line or apparatus and for stick removal. The plant has a chain feeder for the squeezer, a roller squeezer with stick gripping pliers, a chain unloading conveyor and a pliers transferring apparatus or translating device, and is adjustable for adaptation to sticks of various lengths.
Claims18
A plant for squeezing hank yarns, the hanks being carried on sticks, said plant comprising means for conveying the hanks carried on sticks to a squeezing unit, a squeezing unit for squeezing the hanks, and means for removing squeezed hanks from the squeezing unit, characterized in that said means for conveying comprises a chain feeder having two parallel chains formed of interconnected plates, and two parallel chain members formed with plate elements secured to the plates of said chains, each element having an outwardly open notch or cutout, such a notch or cutout being of such dimensions as to receive two overlapped approached parallel hank holding sticks.
A plant for squeezing hank yarns, said hanks being carried on sticks, said plant comprising means for conveying hanks carried on sticks to a squeezing unit, a squeezing unit for squeezing the hanks, and means for removing squeezed hanks from the squeezing unit, wherein said squeezing unit comprises pliers for gripping the sticks, the pliers having jaws thereof of such a shape as to form, when joined at closed position, a cavity for receiving two hank holding sticks at overlapped relationship to each other.
A plant for squeezing hank yans, said hanks being carried on sticks, said plant comprising means for conveying hanks carried on sticks to a squeezing unit, a squeezing unit for squeezing the hanks, and means for removing squeezed hanks from the squeezing unit, wherein said squeezing unit comprises a pair of inlet pliers and a pair of outlet pliers;
- said two pairs of pliers being movable integrally with each other in vertical and longitudinal directions relative to the plant, and heads for mounting the pliers so that the spacing between the pliers of each pair is adjustable in accordance with the stick length by moving said heads near and away from one another.
A plant for squeezing hank yarns, the hanks being carried on sticks, said plant comprising means for conveying hanks carried on sticks to a squeezing unit, a squeezing unit for squeezing hanks, and means for removing squeezed hanks from the squeezing unit, wherein said means for removing comprises a chain unloading device having two parallel chains formed of interconnected hinged plates, and two parallel chain members formed of plate elements secured to said hinged plates of said chains for which alternately one plate element is provided with a cavity for receiving a single hank holding stick, and one or more plate elements have a flat edge, that is free of cavity.
A plant for squeezing hank yarns, the hanks being carried on sticks, said plant comprising a squeezing unit for squeezing hanks carried on sticks, means for receiving squeezed hanks from said squeezing unit, and a translating or transferring device for removing and for transferring hanks from said means for receiving, said translating or transferring device comprising two first or "front" pliers spaced apart from each other;
- two second or "rear" pliers spaced apart from each other and from the first pliers and aligned therewith, the pliers having jaws forming cavities each for receiving only one hank holding stick;
- and guides for guiding movement of said pliers, the front and rear pliers being integrally movable along said guides.
A plant for moving yarn hanks along a path through a squeezing unit, said hanks, when entering said plant, being extended between two sticks inserted therein, comprising:
- means for bringing the sticks to be adjacent to each other;
- means for moving both the adjacent sticks with the suspended hanks through the squeezing unit;
- means for spreading the sticks upon leaving the squeezing unit for widening out the hanks;
- and
- means for withdrawing the hanks from the spread sticks, while removing at the same time said sticks.
A plant for moving yarn hanks along a path through a treating unit, said hanks, when entering said plant, being extended between two sticks inserted therein, comprising:
- means for bringing the sticks to be adjacent to each other;
- means for moving both the adjacent sticks with the suspended hanks through the treating unit;
- means for spreading the sticks upon leaving the treating unit for widening out the hanks;
- and
- means for withdrawing the hanks from the spread sticks, while removing at the same time said sticks.
