Definitions

  • Full tubes are dotted by gripper means from textile spindles located in a-first plane and placed on tube holders located in a second parallel plane, whereupon empty tubes are taken from the tube holders and donned on the spindles.
  • the gripper means are mounted on a carriage which is movable on another carriage transverse to the planes, and with the other carriage parallel to the planes, and an endless chain is connected to the first mentioned carriage to move the gripper means between positions cooperating with the full tubes on the spindles and the empty tubes on the tube holders.
  • the present invention is an improvement of donning and dofiing apparatus by which full tubes having a yarn package thereon are exchanged for empty tubes on whic a yarn is then wound to form a package.
  • Apparatus of this type is particularly used in spinning and twisting machines.
  • a known apparatus has parallel guide bars along which carriages are moved on which a rail carrying grippers is mounted.
  • the guide bars are mounted on a common shaft and turnable about an axis parallel to the plane of the spindles.
  • the grippers Bymoving the carriage along the guide bars, and by angularly displacing the latter, the grippers can be placed in a position for gripping the fullt-ubes, and in another position for placing the full tubes on tube holders on a conveyor band.
  • empty tubes can be taken froin the conveyor band and placed by the grippers on the spindles.
  • the tube transporting means include a first carriage guided for movement parallel to'the first and second planes in'vertical direction, a second 'carriage mounted on the first carriage and guided for movement in a horizontal direction transverse to the vertical planes, and gripper means mounted'on the second carriage and movable with the same between first and second positions located in 'the firstand second vertical planes, respectively.
  • the operating means preferably a stud secured to an endless chain, is connected with the second carriage for moving the same relative to the first carriage the predetermined distance while the operating stud moves along the connecting path portionformed by a chain portion passing over a chain wheel. In this manner, the grippers are moved between positions located in the first and second vertical planes.
  • the second carriage is moved with the first carriage parallel to the first and second planes in vertical direction so that the grippers are moved between positions gripping and releasing tubes on the spindles and the tube holders.
  • the tube holders are spaced from each other half the distance which the spindles are spaced, and every second tube holder carries an empty tube.
  • Full tubes are dolfed from the spindle and placed on empty tube holders, whereupon empty spindles are taken from every other tube holder and donned on the spindles.
  • the conveyor with the tube holders is moved stepwise between positions in which the grippers are located in the planes of the empty tube holders, or in the planes of the empty tubes on every other tube holder in order to doff full tubes from the spindles, or to don empty tubes on the same when the direction in which the controlling chain is driven is reversed.
  • the construction of the invention has the advantage that all required movements of the grippers can be derived from reversal of the movement of a single drive means which effects reciprocation of the drive chain. Another advantage is that the tube transporting apparatus can be mounted in a region of an existent spinning or textile machine where there are no other parts of the machine which would render the addition of the tube transporting apparatus difiicult, or impossible.
