Definitions

  • the invention relates to a device arranged on a carrier of a bobbin changing device of a spinning machine, in particular a ring spinning machine, for gripping an empty or wound sleeve.
  • guards are used to monitor the activity of the gripping members of the bobbin changing device (DE-PS 22 26 077).
  • These monitors are generally in the form of light barriers, the scanning beam of which runs through an area which is taken up by a plurality of coils or sleeves arranged in a row in one phase of the changing process and is or should be left in another phase.
  • the light barrier is interrupted by the coil or sleeve and an error signal is emitted which can stop the progress of the coil change and can call an operator.
  • This known device is thus at best capable of recognizing whether a coil or sleeve is erroneously contained in the plurality of moving sleeves or coils Area is left from which the sleeves or coils have been moved.
  • a sleeve has not been left behind because it was incorrectly not present at all and therefore an error signal cannot be generated.
  • such missing sleeves can also cause errors or damage.
  • a sleeve may have fallen next to it when it was placed on the conveyor belt.
  • the gripping device can then not take up a sleeve and consequently does not put a sleeve on the spindle.
  • the empty spindle shaft is spun.
  • the gripping member cannot pull off a cop either, but instead puts a sleeve on the spun spindle when changing the bobbin, which generally leads to the breakage of any machine part.
  • Such a fault cannot be detected by the known light barrier, since there is no sleeve or coil in play that could interrupt the light barrier.
  • the present invention has for its object to provide a device of the type mentioned in such a way that not only the presence of a sleeve or a coil in a planned sleeve-free or coil-free area and a corresponding signal can be emitted, but also the absence even a single coil or sleeve in a series of sleeves or coils.
  • each device has a sensor for the presence or absence of a sleeve or coil in the device, which is connected to a signaling device.
  • the sensor can be designed either as an electromechanical sensor or as an opto-electronic sensor. In any case, it is ensured that there is better monitoring of the bobbin changing device, which contributes significantly to the operational reliability of the ring spinning machine.
  • the device 1 shown in FIGS. 1 and 4 for gripping an empty or winding-carrying sleeve 9 has a base body 2 which is fastened to a gripper bar 5 of a bobbin changing device of a spinning machine, which is known per se and is not shown in detail.
  • a membrane 3 is located in the base body 2 and a clamping element 4 or 4 ', which can be pneumatically acted upon and is held in its illustrated starting position by a spring element 6.
  • a sleeve 9 shown in broken lines, is clamped inside a housing 8.
  • the clamping element 4 clamps the sleeve 9 between itself and an opposite stop 10 or 10 ′ arranged in the housing 8 and lifts it from its support (not shown in more detail), for example a spindle or a spool plate, during a subsequent upward movement of the gripper bar 5.
  • the tensioning element 4 has a plate-like extension 11 in the rear region and is surrounded in the central region by a sleeve-like stop 12 which has contact surfaces 13 and 14 which are designed as contacts and are directed against the extension 11.
  • the clamping element 4 forms an electromechanical sensor 25 in connection with its plate-like extension and the contact surfaces 13, 14 designed as contacts.
  • lines 17 and 18 are provided on each device I or II or III etc. for gripping a sleeve, which lead to contacts 13 and 14 and are connected to signaling devices 15 and 16, for example designed as warning lamps .
  • a contact point closed via the attachment 11 and the two contacts of the contact surfaces 13 and 14 thus shows either the machine side via a signal device 16 or the spinning point via a signal device 15, at which there is an irregularity.
  • the doffing device can be shut down via the closed contact point.
  • the contact 21 remains closed and, when one of the lines 17 or 18 is subjected to electrical voltage, supplies this voltage via the other line to the signaling device 15, 16.
  • the processing of the given signals has to take this different contact into account.
