The present invention provides a carrying apparatus that prevents an elevating motor and the like from projecting from a stacker crane to hinder the stacker crane from interfering with walls of an automatic warehouse. A traveling vehicleof a stacker crane comprises traveling driving meansfor wheelsand elevation driving meansfor elevating and lowering a platformBoth driving meansare arranged so that a longitudinal direction of both driving meansis almost parallel with a direction in which the traveling vehicleruns. The traveling vehiclecomprises a pair of framesspaced at a predetermined distance from each other and a plurality of connecting members that connect both framestogether. Both driving meansare arranged outside the respective framesWheelsare arranged in the front and rear, respectively, of the traveling vehicleThe traveling driving meansis connected to each wheelAn elevating pulleyfor the platformis arranged between the front and rear wheels. The elevation driving meansis connected to the elevating pulley

Carrying apparatus

On a piecing method of a spinning machine which, after cutting a sliver between normally rotating draft rollers and stationary draft rollers, inserts a leading yarn into the spindle of a twist device and carries out piecing by the restarting of the draft rollers, restarting of the twist device and running of the leading yarn, approximately all the fibers comprising the tapered tip of the cut sliver form the joint part by being entangled in the leading yarn. As almost all of the fibers comprising the tapered tip of the cut sliver contribute to the joint part, the success rate of piecing is increased and a stronger joint part may be formed.

Piecing method for a spinning machine

This invention is related to a yarn piecing apparatus of a spinning machine arranged with a holding member (12) that holds the parent yarn (Y') which is inserted in the hollow spindle (6) of the spindle member (5) which is seperated from the nozzle member (2), at a predetermined tension so that it does not rotate due to the rotating air current from the nozzle member. As the parent yarn (Y') inserted in the hollow spindle (6) of the spindle member (5) which is seperated from the nozzle member (2) is held by the holding member, there is no rotation of the parent yarn (Y') by the rotating air current and consequently, fibers can be reliably attached to the parent yarn (Y') and the success rate of yarn piecing can be increased.

Method and apparatus for piecing yarn slivers to a parent yarn in a yarn

A spinning apparatus having a spinning section for forming yarn by applying a rotating air current of predetermined air pressure to a supplied fiber bundle and twisting the yarn while opening an end of the fiber bundle, and having a piecing section for reverse threading a spun yarn end into that spinning section. The spinning apparatus has a high pressure application member for applying high pressure air at a pressure higher than the aforementioned predetermined air pressure to such fiber bundle during the predetermined time after the spun yarn end is reverse threaded into the spinning section. The high pressure application member includes a first air circuit for supplying the aforementioned predetermined air pressure, a second air circuit that supplies air at a pressure higher than the aforementioned predetermined air pressure and a change-over member between the first and second air circuits.

Method of and apparatus for spinning and piecing yarn

A spinning apparatus having a nozzle (n1) that exerts the actions of a rotating air current on the fiber (f), a hollow spindle (s1) and a fiber introduction member (e2) positioned opposite the inlet end part (s1') of the hollow spindle with a fiber guide member (E) arranged with a fiber guiding surface (e9) twisted in the rotation direction of the air flow and the fiber introduction member (e2) projecting from the fiber guide member toward the hollow spindle. The end part of the guide member (E) may be formed into a flat or a curved shape whereby a spun yarn with improved fiber evenness and having higher strength, a round cross section, a better exterior and resembling blend yarn which differs from core yarn, can be spun. Furthermore, improvements in the spinning properties and success rate of yarn piecing can be realized.
