Definitions

  • the invention relates to a device for producing a lap roll, in which the lap is wound onto a core driven by a continuous endless belt, wherein the endless belt is guided in a loop around the core over a plurality of guide rollers and the core between two, the core is held in the radial direction superior winding discs.
  • a device wherein a lap roll is formed using a driven and endlessly circulating belt.
  • a cotton wool is fed between two deflection rollers of a belt loop.
  • Within the belt loop is a rotatably mounted sleeve, which is driven by the movement of the belt via friction.
  • the sleeve is clamped between two winding discs, which project beyond the sleeve in the radial direction.
  • the supplied cotton is wound onto the sleeve.
  • the wadding web - seen in the radial direction of the sleeve - is wound in layers on the sleeve.
  • a very compact winding can be formed at high winding speed.
  • the two winding disks support the winding process, in particular for achieving a clean edge region of the wound to be produced. That is, during the winding process, the edge regions of the wound cotton web are passed through the winding disks, so that lateral fraying is avoided.
  • the running in the region of the loop between the winding discs belt is to be guided at a small distance from the guide surfaces of the winding disks, on the one hand to avoid jamming of fibers in this area and on the other hand to prevent wear of the belt edges. Since the movement of the belt at the inlet between the winding disks transverse to the rotational movement of the winding disks, this would lead to a wear of the belt edges, if These would come on the winding discs quite to mooring. This can lead to fraying of the belt edges, which in turn have a negative effect on the formation of clean edge parts of the cotton wool to be created.
  • a device wherein at least at one point of the belt course outside the loop in the region of both side edges of the belt means are mounted, the measures for returning the belt in a predetermined tolerance range trigger as soon as the belt transversely to his Drive movement moves out of this tolerance range.
  • the term "tolerance range” indicates the range of movement of the belt with respect to the belt width, which ensures that the belt in the area between the winding disks still has a sufficient lateral distance to the winding disks.
  • a lateral drift of the belt from its mounted position can e.g. during the winding process by heating the belt, which can cause a deformation of the belt with respect to the guide elements by itself.
  • the means are arranged between the successive deflection rollers, which guide the belt before entering the loop.
  • the means comprise sensors or elements with sensors which are connected to a control unit. This makes it possible to process the signals received from the control unit accordingly.
  • control unit is connected to the drive of the winding device, it is possible to stop this drive, if a return of the belt over a predetermined period can not be done.
  • the return of the belt in its tolerance range can, for. B. via an adjusting device, which is connected to the control unit. It is proposed to steer the adjusting device at a bearing point of a deflection roller in order to move the bearing point in the radial direction in or against the inlet direction of the belt to the deflection roller.
  • the opposite bearing point of the deflection roller, on which the adjusting device does not act, is designed, or mounted, so that a pivoting movement of the bearing point, which is acted upon by the adjusting device, is made possible.
  • the running direction of the belt is thereby corrected by pivoting the inlet line of the belt to the deflection roller.
  • the infeed line marks the line at which the belt hits first when entering the idler pulley
  • the signals supplied by the sensors to the control unit are evaluated on the basis of predetermined and stored criteria in order to deliver corresponding control commands to the adjusting device and / or the drive of the winding device.
  • the means consist respectively of guide pulleys arranged in the region of the lateral edges of the belt, which are fastened on a rotatably mounted roller via which the belt is guided and the guide pulleys - viewed in the radial direction - at least over a partial region with one of the side edges the belt facing inclined surface are provided, which, seen in the radial direction to the outside, diverge to each other.
  • the belt strikes one of the inclined surfaces during a lateral displacement, the belt is returned to its tolerance range under the action of the belt tensioning force and the resulting force in the direction of the belt center.
  • the surfaces of the guide discs which are directly opposite the side edges of the belt, parallel to these side edges and the distance between these surfaces is greater than the width of the belt , This ensures that the belt, when it is within the tolerance range, does not touch the guide disks. Smaller and short-term lateral displacements in which no very high transverse forces occur in the belt can be absorbed by the provided parallel surfaces, without the belt edges stand out from the roller.
  • the sensors for monitoring can be arranged in the region of the inclined surfaces of the guide discs.
  • roller with the guide discs is mounted adjustably in the direction of its axis of rotation.
  • the bearing elements of the pressure roller sensors are assigned, which monitor the radial displacement of the axis of rotation of the pressure roller, which occurs when a side edge of the belt from the roller in the region of the inclined surface stands out.
  • the sensors are also connected in this case to the control unit, which is connected on the one hand with the drive of the winding device and on the other hand with an adjusting device, via which the belt profile is adjustable transversely to its drive movement. With this device, one obtains on the one hand a possible automatic return of the belt over the inclined surface in its tolerance range and on the other hand, a monitoring of this process, unless this feedback can be done.
  • the elements each consist of at least one rotatable mounted scanning roller, which are mounted in the region of the side edges of the belt, wherein the peripheral surfaces of the sensing rollers are opposite to the side edges and one sensor is provided for monitoring the speed of these sensing rollers ,
  • the contact rollers are arranged so that the belt edges do not set the feeler rollers in rotation, if the belt moves within the tolerance range.
  • the sensing rollers are arranged in pairs to detect an accurate detection of the lateral belt displacement.
  • the axes of the paired scanning rollers can be arranged (in the radial direction) pivotable about an arranged between the sensing rollers pivot axis. This ensures that in a lateral drifting of the belt, the respective belt edge is supported evenly by both sensing rollers, whereby the support increased and thus the resulting surface pressure on the belt edge is reduced. This in turn reduces the wear of the belt in the edge area.
  • At least one spring element is mounted in the region of the sensing rollers whose spring action counteracts the pivotal movement of the sensing rollers about the pivot axis.
  • This free pivoting (without the action of the belt) is limited to this axis and fixed the touch rollers in a basic position to the belt.
  • the spring force of the spring element is designed so that a pivoting movement is ensured by the application of the belt edge, so that the laterally displaced belt is supported on both rollers simultaneously.
  • additional guide elements eg guide rollers
  • guide rollers can be arranged above and below the touch rollers across the width of the belt.
  • Fig. 1 shows a winding device 1, which has already been shown in the already prepublished EP-A1-929 705 in a similar form and described in detail. Therefore, the operation of this winding device is described only superficially in the following description.

  • a tension roller R6 is pivoted about an axis 4.
  • the lap roll WW rotates in the direction of rotation D.
  • the drive of the calender rolls K1-K4 is stopped, while the drive of the lap roll WW via the belt R is still in operation.
  • the cotton wool in the region of the guide plate 6 is separated.
  • the winding device 1 is stopped.

  • the cotton roll WW still in the loop S should be ejected and the winding device prepared for the formation of a new cotton wool wrap.
  • a monitoring or guiding device 10 is arranged in the region in front of the roller R1. Different embodiments are shown in FIGS.
  • the belt edge Rs is not worn by friction on the winding disks W1, W2, it is necessary to maintain a minimum distance a to these winding disks.
  • the belt R drifts to one side or the other during the winding process. He can thus reach from a predetermined tolerance range, whereby the belt edge can come to rest on one of the winding disks. If the resulting friction between the belt and the respective winding disk is maintained, it can lead to fraying in the belt edge Rs. There is a risk that these frayed fibers (protruding line ends) from the edge area of the Wickels WW be dissolved out, which has a dirty wrap to episode. This in turn has negative effects in subsequent processing on the comber, which quality losses must be accepted.
  • a roller 12 is schematically shown, which is mounted with respect to the transport direction of the belt R in front of the deflection roller R1 in the machine frame.
  • the roller 12 has at its ends in each case a guide plate 13, 14. These discs 13, 14 are fixedly mounted on the roller 12.

  • this device is sufficient to return the belt R in the specified tolerance range. However, if the resultant force RR is insufficient to return the belt R to its tolerance range, it is useful to monitor this to take appropriate action.
  • one or more sensors S1, or S2 are attached, which emit a signal as soon as the belt edge Rs is in this area.
  • the respective sensors S1, S2 are connected to a control unit ST, in which the signals emitted by the sensors S1, S2 are processed.

  • a signal pulse is output to the control unit ST, for example at the instant t1 (see FIG. 7). If, as shown in FIG. 7, the signals of the sensor S1 are transmitted only during a time interval ta, no control pulse is output from the control unit ST to the valve 26. That is, the belt R is returned, for example, over the inclined surface 16 after a short time until time t2 back into its tolerance range in which it rests completely on the roller 12 again.
  • the sensor S1 may be an optical sensor, pressure sensor, or other design.
  • Valve 26 activated.

  • the axis 30 is displaced in the region of the receptacle 31 counter to the drive direction AR of the belt R. As a result, the drive direction of the belt R shifts to the right.
  • the control unit ST again receives signal pulses from one of the sensors S1, S2, the valve 26 is likewise displaced into the corresponding position after a time interval tt via the control unit ST, by a transverse displacement of the belt R, or a return of the belt R in its tolerance range.
  • the drive AN of the winding device 1 is stopped at time t6 via the control unit ST and the connecting line 23. That is, it was not possible by the internal control device to return the belt back into its tolerance range, which can have different causes.
  • the device After stopping the winding device, the device must now be manually inspected and possibly appropriate measures are initiated. With this device, it is thus possible to trigger corresponding control pulses based on predetermined time intervals in the control, on the one hand to return the belt back into the tolerance range, or to avoid a steady lateral drift of the belt.
  • a further embodiment is shown, wherein the roller 12, over which the belt R is guided, a pressure roller 38 is associated, which rests under the action of spring elements F1, F2 with a low contact pressure on the belt R.
  • the spring elements F1, F2 are each arranged in combination with sensors S3, S4. The arrangement is made such that the sensors S3, S4 can scan the displacement of the spring elements F1, F2.

Due to the one-sided lifting of the belt and the pressure roller 38 is lifted against the spring force of the spring element F2 and takes, for example, the dashed line position.
  • This shift of the pressure roller is detected by the sensor S4, which outputs its signals (pulses) to the control unit ST.

  • a sectional view EE of Fig. 5 is shown, wherein it can be seen that the sensing rollers 41, 42 seen the belt R seen in the vertical direction up and down. This ensures that the belt edge Rs in the case of lateral drifting of the belt R in any case comes to rest against one of the feeler rollers 41, 42, and 44, 45.
  • the feeler rollers 41 and 45 are each provided with a sensor S5 or S6, which scans the rotational movement of the respective roller, which occurs when one of the rollers comes into contact with the belt edge Rs. This is the case when the belt R moves laterally out of the predetermined tolerance range.
  • the valve 26 is actuated via the control unit ST, which receives the signals from the sensor S5 via the path 51, whereby the axis 30 of the roller R5 is pivoted via the cylinder Z1 to the belt again in due to its original location. If this control intervention is successful, the belt R moves back into the position shown in FIG. 5 (tolerance range), whereby the belt edge Rs again moves away from the circumference of the follower roller 41. That is, at time t4, the feeler roller 41 is again at a standstill.
  • control unit ST By depositing a specific control profile in the control unit ST can be exactly predetermined, at which time the control pulse is triggered based on the signals of the sensors for balancing the course of the belt. Likewise, it can be precisely predetermined how long the time interval in which the sensors deliver signals until an emergency stop of the machine should be triggered. With the proposed device to obtain a safe and flexible monitoring system to keep one hand, the wear of the belt edges Rs to a minimum and on the other hand timely stop the machine operation, unless the belt R is not due to appropriate control devices in its predetermined tolerance range.
