Definitions

  • the invention relates to a tube gripper for a cheese change unit according to the preamble of claim 1.
  • cross-spool changing units In connection with cross-wound producing textile machines, for example automatic spooling machines, so-called cross-spool changing units have long been known.
  • Such cheese change units are along the workstations of the textile machines movable operator, which intervene automatically when needed at the jobs helping. Such a requirement is given, for example, if the cross-wound bobbin has reached a predetermined size at a workstation. In such a case, the cheese change unit runs to the relevant job, positions itself there and exchanges the finished cross-wound bobbin for a new empty tube.
  • Such cross-coil changing units for example, in the DE 195 24 946 B4 and the DE 10 2007 036 696 A1 are described, each have a variety of handling devices that come during a change process according to a predetermined program used.
  • Such cross-coil changing units have, for example, a frame opener, a frame lifter, a coil guide device and a tube gripper.
  • a cross-coil changing unit which has a tube gripper, which has a prismatic, by means of an adjusting mechanism mechanically adjustable sleeve holder for positioning an empty tube and a pivotable by a pneumatic cylinder gripper fingers for fixing the empty tube on the sleeve holder.
  • the subsequent sleeve transfer position of the empty tube is always determined by the position of the prismatic sleeve holder.
  • a cheese change unit with a comparable tube gripper is also in the DE 10 2007 036 696 A1 described.
  • the tube gripper consists of a arranged on a base body of the tube gripper prismatic sleeve holder and a movable by means of a pneumatic cylinder gripper fingers, which can be lowered onto an empty tube positioned in the sleeve holder.
  • cross-coil changing units have proven themselves in practice, but have the disadvantage that their sleeve grippers always have to be readjusted manually when changing the sleeve format.
  • cheese change units can always handle only one empty tube type, with the result that such cross-coil changing units can be used only in a one-part operation of a textile machine.
  • sleeve feeders have already been developed in connection with reciprocating machines, which automatically adapt to the respective tube format when gripping an empty tube.
  • This intermediate frame of the cheese change unit can, depending on whether cylindrical or conical empty tubes must be handled, are pivoted in a first or in a second working position.
  • Such cross-coil changing units are quite complex in their structural design, with the result that the production of such cheese change units is quite expensive.
  • Cross-coil changing units with tube grippers which are arranged on a pivotally mounted intermediate frame, therefore could not prevail in practice.
  • This known tube gripper which is also applicable to cheese change units, is designed so that he himself automatically adjusts to the diameter and the shape of an accommodated empty tube, wherein also the center longitudinal axis of the recorded empty tube, regardless of the shape or the diameter of the empty tube, during the sleeve transfer is shifted so that it in a sleeve transfer position with the axis of rotation of the coil frame of a job arranged sleeve receiving plate coincides.
  • the present invention seeks to develop a tube gripper for a cheese change unit, on the one hand reliable and without additional modifications the replacement of empty tubes of different sleeve formats in the creel of jobs of a cheese-producing textile machine allows and on the other hand inexpensive to produce and insensitive against harsh environmental conditions.
  • the inventive design of a tube gripper has the particular advantage that when taking over an empty tube from a working empty empties memory immediately a reliable alignment and fixation of the axis of rotation of recorded empty tube according to the present, predetermined sleeve format.
  • the two spaced arranged 3-point clamping devices of the tube gripper according to the invention each formed by the sleeve holder, a movable probing lever and a movable counter-clamping lever, ensure that the axis of rotation of the recorded empty tube, immediately according to their sleeve format, the known and is deposited in a storage device of the cheese change unit, is aligned so defined that the axis of rotation of the empty tube in the region of a sleeve transfer position coincides with the axis of rotation of the sleeve receiving plate of the creel of the relevant job.
  • a cross-coil changing unit equipped with a tube gripper according to the invention can therefore easily handle one after the other empty tubes of different diameter and / or different sleeve shape (cylindrical or conical), that is, transfer from a working empty envelope storage in a sleeve transfer position of an associated creel of a job.
  • the empty tube held ready by the tube gripper in the sleeve transfer position can be safely taken over by the rotatably mounted sleeve receiving plates of the coil frame when closing the coil frame.
  • the tube gripper has two probing levers pivotally mounted on a central carrier of the tube gripper via a first axis and two counter-clamping levers mounted pivotably on a second axis of the central carrier.
  • the two probing levers are pivotable by a pneumatic cylinder in the direction of the empty tube and each positively coupled with an associated counter-tensioning lever.
  • a sliding and guide element arranged on the feeler lever corresponds to an associated curve contour integrated into the counter-tensioning lever.
  • the two acting on the empty tube probing lever and the two counter-clamping lever form in conjunction with the sleeve holder of the tube gripper two spaced-apart 3-point clamping devices that align the empty tube both in accordance with regulations, as well as secure.
  • the counter-clamping lever can each be acted upon by a spring element so that its curve contour always bears against the sliding and guide element of the probe lever.
  • the sliding and guide element of the second probe lever is so formed and so Defined adjustable that when closing the tube gripper, the rotation axis of an empty tube is automatically pushed into a predetermined position.
  • the sliding and guiding element is preferably designed as an eccentrically mounted adjusting bolt, which, acted upon by an electric motor drive, defined in predeterminable working positions can be positioned.
  • the center of the second 3-point clamping device and thus the position of the axis of rotation of the empty tube can be set exactly on the working position of the arranged on the second feeler sliding and guide member corresponding to the curve contour of the associated counter-clamping lever when swinging the probing lever ,
