  • the present invention relates to a method and device for automatically changing sliver cans on sliver producing machines and more specifically, to a method and device for transferring sliver cans supported on a carriage onto a rotating disk located beneath the delivery end of a sliver producing machine and form the disk back to the carriage.
  • sliver producing machine may be a drawing frame or any other machine acting on textile material prior to the spinning of the material into yarns.
  • transfer mechanisms have already been suggested by means of which an automatic transferof a can from the carriage onto the operating machine may be carried out and such known transfer arrangements include two mechanisms, one of which moves a carriage with cans thereon in substantially horizontal direction and the other mechanism lifts an empty caninto delivery position on the machine and lowers a filled can from the machine onto the carriage.
  • Such known transfer arrangements are however, complicated and correspondingly expensive.
  • the method according to the present invention of transferring sliver cans supported on a carriage onto a rotating disk having an upper surface at a given elevation and being located beneath the delivery end of sliver producing machine and from the disk to the carriage mainly comprises the steps of supporting at least one can at transversely spaced bottom portions thereof on the carriage with the bottom of the can at an elevation below the given elevation while leaving an intermediate bottom portion of the can unengaged, moving the carriage and the can thereon toward the disk and forcing the can upwardly along a fixed upwardly inclined plane having a trailing end adjacent the disk at an elevation slightly higher than said given elevation so as to raise the bottom of the can above the upper surface of the disk, stopping movement of the carriage after the can bottom has moved from the trailing end of said plane onto the upper surface of the disk, subsequently moving said, carriage beyond. the disk while forcing the can to Ice 3,307,226

  • the free inner edges of the flanges 26 are spaced a given distance from'each other as can be clearly ascertained from FIGS. 2 and 3.
  • Two pairs of swivel casters 28 are mounted on the inwardly extending flanges 26 in any convenient manner, as schematically illustrated in FIG. 2, so that the carriage 20 may roll along the supporting surface.
  • a plurality of cans 11, for instance three as shown in the drawings, are normally supported with transversely spaced bottom portions thereof on the flanges 26 of the carriage and the cans 11 extend through the openings 22 of the top plate 21 of the carriage so that the cans 11 are forced to move with the carriage while being free to move toward and away from the flanges 26.
  • the flanges 26 form therefore a pair of engaging means fixed to the carriage for engaging transversely spaced bottom portions of the cans while leaving an intermediate bottom portion of the cans free and unengaged, while the openings 22 in the top plate 21 of the carriage and the downwardly extending annular flanges about the openings form guide means fixed to the carriage and guiding the cans for movement toward and away from the engaging means while substantially preventing the cans to move in direction of the movement of the carriage relative to the latter.

  • This arrangement may also include as shown in FIG. '3 a .second electric motor 30' mounted in any convenient manner on an extension of the frame of the machine 10, not shown in the drawing, and driving by means of a transmission 31 a friction roller 33' mounted on a tiltable arm 34 and pressed by compression spring 36' against one side wall of the second carriage. In this case the row of the guide rollers 38 is extended to engage also the opposite side wall of the second carriage.
  • the coupled together carriages 20 are moved in longitudinal direction by the motor 30' and the drive roller 33' connected thereto so that the leading can 11 on the leading carriage 20 moves upwardly on the upwardly inclined member 14 to move, upon further movement of the carriage, onto the upper surface of the disk 12.
  • the motors 30 and 30' are stopped preferably automatically by any known arrangement not forming part of the present invention and which may for instance include an electric eye mounted on the machine in such a manner that the light beam is interrupted when the leading can 11 is at the proper location centered on the disk 12 to operate thereby in a known manner a relay interrupting the current supply to the motors and 30 and start at the same time the machine 10 to deliver a sliver band into the can located below the delivery end of the machine 10.
  • the length of the band delivered into the can 11 on the disk 12 may be measured in a known manner by an appropriate measuring device known in the art and not forming part of the present invention and the band is then severed in known manner while at the same time the motors 30 and 30' are started and operated for a length of time until the next can 11 of the first carriage is moved in the aforementioned manner onto the rotating disk while the filled can 11 is moved at the same time from the upper surface of the disk 12 onto the upper surface of the downwardly inclined member 16.
  • the movement of the carriages is again stopped in the aforementioned manner and the three cans of the first carriage will assume the position as shown in FIG. 1.
