Definitions

  • the invention relates to a method for removing full bobbins from a spinning machine and for feeding empty bobbin tubes to the spinning positions of the spinning machine with a transport device, which is provided with receptacles that receive full bobbins or empty bobbin tubes, and an automatic device for removing the full bobbins and an automatic device for feeding empty bobbin tubes is assigned, as well as a spinning machine.
  • empty bobbin tubes in a batch of full bobbins can be caused, for example, by the failure of one or more spinning positions or by spinning only incomplete batches of bobbins at the spinning positions.
  • These empty bobbin tubes must either be rejected manually by an operator or by appropriate additional automatic devices.
  • the object of the invention is to provide a method and a spinning machine of the type mentioned at the outset by which the removal of empty bobbin tubes from the spinning machine is prevented.
  • This object is achieved in that it is checked whether the receptacles coming to the device for removal have full bobbins or empty bobbin tubes, and that, depending on this test, the device is not actuated when an empty bobbin tube comes in.
  • the empty bobbin tubes remain on the receptacles of the transport device and do not have to be sorted out by an operator or a corresponding automatic device in front of the subsequent machine, for example a winder.
  • the device is checked whether the receptacles that feed the device for feeding empty bobbin tubes already contain empty bobbin tubes, and, depending on this test, the device is not actuated when empty bobbin tubes feed.
  • the supply of empty coil sleeves to the already occupied receptacles of the transport device is interrupted in order to avoid placing two empty coil sleeves one above the other. In this way, possible damage to the elements of the feed device, to the receptacles of the transport device or to the empty bobbin tubes themselves can be prevented.
  • a spinning machine with a transport device for removing full bobbins and for feeding empty bobbin tubes is provided, which is provided with receptacles which take up full bobbins or empty bobbin tubes and which is assigned a device for removing full bobbins and a device for feeding empty bobbin tubes wherein the device for removing the full bobbins is associated with means for distinguishing between full bobbins and empty bobbin sleeves, which are connected to an actuation of the device for removing the bobbins when a signal indicating the supply of a full bobbin is received.
  • the device for feeding empty bobbin tubes is assigned means for detecting already occupied recordings, which are connected to a control unit actuating the feeder only when a signal indicating an empty recording is received. If there is therefore already an empty bobbin tube on a receptacle of the transport device, no empty bobbin tube is fed to this receptacle. This avoids double mounting of the recordings.
  • a ring spinning machine has two opposite machine sides (3 and 4), each of which is provided with a large number of spinning positions.
  • the ring spinning machine is provided with two machine end frames (1 and 2) on both ends.
  • the ring spinning machine is connected to a winder, not shown, as will be explained in the following.
  • a transport device (7) runs around the ring spinning machine and along the two machine sides (3 and 4) for removing full bobbins from the spinning stations and for delivering empty bobbin tubes to the spinning stations.
  • the transport device (7) is arranged below the spinning stations. In a known manner, the full bobbins produced at the spinning positions on one machine side (3 or 4) are removed in one operation with the aid of an automatic changing device and transferred to the transport device (7).
  • This changing device then removes the empty bobbin tubes already delivered to the individual spinning stations from the transport device (7) and transfers them to the spinning stations at which they are now wound with yarn.
  • the full bobbins are removed by the transport device (7) and fed to the subsequent winding machine.
  • the transport device (7) contains a vertically standing, flexible, endless conveyor belt, which is guided around the latter by means of deflection rollers (8) arranged in the region of the front ends of the ring spinning machine. At least one of the deflection rollers (8) is provided with a drive and drives the transport device (7) according to FIG. 1 in a counterclockwise direction.
  • receptacles (11) are arranged at a distance of half the division of the spinning positions, which are provided with vertically upwardly projecting pins, as can be seen from FIGS. 2 and 3.
  • the empty bobbin sleeves (12) and the full bobbins (13) are placed on these pins.
  • transport device (7) is described in detail in DE-A 38 12 342 and is therefore not explained in more detail below.
  • the transport device (7) can also be designed in such a way that the empty bobbin cases (12) and the full bobbins (13) are transported along a transport path on plates provided with pins, whereby the plates are guided with the aid of drivers arranged on the conveyor belt.
  • Arranging the receptacles (11) at a distance of half a division on the transport device (7) serves to be able to deposit full bobbins (13) on the transport device (7) as long as the empty bobbin sleeves (12 ) are on it.
  • empty bobbin tubes (12) and full bobbins (13) cannot be arranged on the transport device (7) at the same time during the changing process. 2 and 3, the receptacles (11) are arranged at a distance of an entire division from one another for better clarity.
  • the transport device (7) On the end face of the ring spinning machine assigned to the machine end frame (1), the transport device (7) is assigned a device (6) for feeding empty bobbin tubes (12) as an extension of the one machine side (3) (FIG. 2). The empty bobbin tubes (12) are fed to this device (6) from the winding machine, which is shown by the arrow (10).
  • a device (5) for removing the full bobbins (13) is assigned to the transport device (7) as an extension of the opposite machine side (4). These full bobbins (13) are fed from this device (5) from the downstream winding machine, which is indicated in Fig. 1 by the arrow (9).
  • the device (5) and the device (6) are only in operation as long as the transport device (7) rotates around the ring spinning machine. This is usually the case when the spinning stations for yarn production are in operation. While the transport device (7) rotates in the direction of the arrow according to FIG. 2, empty receptacles (12) are supplied to the receptacles (11) by the device (6).
  • the device (6) contains a downpipe in which at least one empty coil sleeve (12) is held in a vertical orientation. The lower opening of the downpipe can be closed using a closing mechanism (25).
  • a chute (26) is provided below the downpipe and can be brought into a position coaxial with the downpipe and which takes over the guidance of the empty coil sleeve (12) onto a corresponding pin of a receptacle (11).
  • the closing mechanism (25) is controlled by a controller (23) which is connected to the drive of the transport device (7). This drive takes place in cycles and is controlled by the control (23) in such a way that it stops briefly at the pitch of the receptacles (11) when a receptacle (11) is located below the chute (26). Then the closing mechanism (25) of the downpipe is opened so that an empty coil sleeve (12) can center on the pin of the receptacle (11). The chute (26) then moves upward in order to enable this empty bobbin tube (12) to be transported further by the transport device (7).
  • the device (5) for removing full bobbins (13) also has a control (17) which, with the aid of a gripping arm (15) actuated by a lifting cylinder (14), successively removes full bobbins (13) from the transport device (7) and passes it to a transport device for further transport to the winding machine (arrow 9).
  • This control (17) of the device (5) like that of the device (6), is designed such that the transport device (7) is stopped briefly each time a full spool (13) is located below the gripping arm (15) .
  • the transport device (7) is assigned a detection device, for example a light barrier (20), in front of the device (5) in the transport direction. can distinguish the full bobbins (13) from empty bobbin tubes (12).
  • the transmitter and receiver of the light barrier (20) are arranged so that the light beam is interrupted by a coil (13) wider than an empty coil sleeve (12), but not by an empty coil sleeve (12).
  • the light barrier (20) is arranged at a distance from one division of the receptacles (11) in front of the gripper arm (15), so that it detects the full spool (13) which is to be gripped next by the gripper arm (15) .
  • the light barrier (20) is connected to the controller (17) (arrow 18), which in turn actuates the lifting cylinder (14) to actuate the gripping arm (15) by means of a valve (16) (arrow 19).
  • the gripper arm (15) is actuated by the movement of the transport device (7) by the path between the light barrier (20) and the gripper arm (15).
  • the transport device (7) is in the Area in front of the device (6) another detection device, for. B. again a light barrier (21), which detects the presence of an empty coil tube (12) on a receptacle (11) and forwards it to the controller (23) of the device (6).
  • the light barrier (21) is arranged at twice the pitch of the receptacles (11) in front of the chute (26), so that, for example, an empty coil sleeve (12) is detected after a further two cycles of the drive of the transport device (7).
  • a corresponding signal is transmitted to the controller (23) (arrow 22), which controls the closing mechanism (25) in such a way (arrow 24) that the downpipe is not is opened when the receptacle (11) equipped with the empty coil sleeve (12) is below the downpipe.
  • the light barriers (20, 21) described above are only one embodiment for the means for distinguishing between full coils (13) and empty coil sleeves (12) or for the means for detecting already occupied recordings (11). In the same way Other designs of mechanical or non-contact sensors can also be provided.
