Definitions

  • the invention relates to a method and a device for traversing a flat can on a textile drafting system according to the preambles of claims 1 and 5.
  • the traversing has an influence on the storage of the fiber sliver. If there are errors in the storage of the sliver, this is noticeable when the sliver is removed.
  • the duration of a can filling is determined by the realizable delivery speed of the sliver and the related traversing speed of the flat can. The quality of the sliver storage is thus also determined by the way in which it is moved.
  • the flat jug differs significantly in shape from a round jug.
  • the flat jug has a rectangular base, the elongated side walls being delimited by narrow end walls.
  • the flat jug has a height-adjustable can plate. When the flat can is empty, the can plate is positioned below the upper edge of the can.
  • the flat can is filled in that the delivery device (turntable) is arranged stationary and for this purpose the flat can is moved back and forth, i.e. the flat can is changed.
  • the sliver is laid down in a cycloidal shape over the length of the movable can plate. Several such layers of deposited sliver form a sliver column.
  • the flat can During the translation of the flat can, its speed is matched to the delivery speed of the delivery device.
  • the back and forth movements of the flat can take place at a constant speed up to the turning point. It has so far been customary to move the flat can at a constant speed value during traversing, i.e. the flat can impacts at a constant speed on the limit set up as a reversal point.
  • the limit is dimensioned so that it absorbs the kinetic energy of the flat can. So far, it has been important to achieve an extremely rapid reversal of direction with the least possible delay in order to move the flat can immediately in the opposite direction with an analog speed value.
  • the sudden reversal of the movement has the result that the sliver column in the flat can is very shaken and fluctuates. Sudden changes in speed or acceleration occur at the reversal point. This manifests itself in violent impacts on the flat can. Such periodic impacts interfere with the sliver storage and ultimately the structure of the sliver column. The fiber sliver is pressed in the area of the end walls of a flat can by these impacts from the desired storage path. Such faults increase the risk of the tape breaking when the tape is pulled off.
  • the translational movement continues to cause the fiber ribbon column to sway strongly at the reversal points, which also interferes with the placement of the ribbon loops on the end faces of the can.
  • the swaying creates a gap between the band column and the wall for a short time. In this space, the ribbon loop can be turned off and jammed. This would also prevent proper tape removal. This disrupts the sliver storage and the structure of the band column.
  • DE-AS 11 58 420 describes, in FIG. 1 there, a device which oscillates a rectangular container with a uniform traversing speed.
  • the container stands on a platform that is connected to a fork.
  • a pin engages in this fork, which is guided by an endless chain and deflected in the direction by a gear wheel. Since the bolt remains in engagement with the fork, this deflection of the bolt via a gearwheel reverses the direction of the platform and thus reverses the direction of the container on a traversing path. Due to the fixed geometry of the gear wheels, a sinusoidal change in the traversing speed inevitably takes place for the section which corresponds to a radius of the gear wheel. The change in the uniform traversing speed on the reversal path can only be sinusoidal.
  • the device has not, however, eliminated the shortcomings and reservations described for traversing flat cans.
  • a change in the traversing speed in DE-AS 11 58 420 is always associated with a fixed change in the reversal time for an unchangeable reversal path. Consequently, a change in the reversal time is only feasible depending on a change in the traversing speed. If, for example, an increase in the traversing speed is necessary, this leads to an undesired shortening of the reversal time and thus to undesired, unfavorable acceleration values. This has an adverse effect on the sliver storage. In the practical spinning mill there is, for example, the requirement, in the case of a changed traversing speed (for example when changing parties), the reversal time to keep constant.
  • DE-AS 11 58 420 does not provide any information as to how the reversal time could be kept constant when the traversing speed changes. There is also no evidence of a change in the reversal path or the reversal time with an unchanged traversing speed.
  • DE-AS 19 23 621 therefore intends only to provide an improved method for storing fiber slivers in rectangular cans.
  • DE-AS 19 23 621 (column 3, lines 48-54) explains, due to the cycloid-like turns and the zigzag or meandering turns lying next to each other, only a higher filling of a rectangular jug can be achieved, with the input mentioned disadvantages have not been eliminated.
  • DE-AS 1158420 has the peculiarity that a cardboard storage container is fixed on the conveyor rollers of a platform during the filling process, the conveyor rollers having no function for the oscillation of the storage container.
  • DE-AS 2918995 proposes to lock a container on a plate during filling, the plate being moved by means of a coordinate control device.
  • the coordinate control device can only implement the XY coordinates of the plate in accordance with two mechanical control curves. A single speed is set and maintained for the filling process.
  • EP 457 099 which forms the preamble of claims 1 and 5, recognizes that when a flat can is moved back and forth, relatively large masses of sliver are moved while it is being filled.
  • the speed of the translational movement of the flat can is briefly increased shortly before the reversal point is reached and, after this point has been exceeded, reset to a predetermined translational speed (column 3, lines 56-58, column 4, lines 1-4). . It was also not possible to prevent the storage of the sling on the face from being disturbed.
  • the device for filling a flat can is equipped with a movable carriage arrangement for carrying the flat can.
  • the carriage arrangement consists of upper and lower carriages which are moved automatically under the influence of a programming device and control devices.
  • the jug is on the uppercarriage. Above the jug there is a rotating turntable that delivers the sliver.
  • the jug is held on the upper carriage in the area of the lower jug wall.
  • the displacement device is equipped with detachable holding elements on which the flat can is suspended.
  • These holding elements are designed as grippers, which interact in pairs and can be pivoted about the vertical axis. The grippers grip the flat can in the area of the upper edge of the can and on the narrow side.
  • the device enables a slightly higher translation speed than the solutions in the prior art, it does not allow the sling to be disturbed when it is deposited near the end face.
  • the object of the invention is to improve the sliver storage and the structure of the band column when traversing a flat can so that the delivery and traversing speeds can be increased.
  • the flat can is moved in the direction of the end walls along a traversing path and moved back along the same. This process is repeated periodically when filling the can.
  • the flat can receives different moments of motion during the movement along the traversing path in the vicinity of the reversal points.
  • the traversing path is the path between two reversal points. Starting from the point of reversal, this traversing path is deliberately divided into an acceleration path which merges into a path which is characterized by an essentially uniform movement. It connects to a braking section. The opposite reversal point has been reached.
  • An acceleration path follows in the reversal of the traversing path. It follows a route on which an essentially uniform movement is realized analogously.
  • the end is a braking section. Braking and acceleration distances are characteristic of every turning point.
  • the braking and acceleration sections are therefore referred to as the reversal path.
  • Another feature is that the traversing speed of the flat can in the vicinity of the reversal point is steadily reduced so that the speed of the flat can running toward the reversal point is reduced to zero at the reversal point in accordance with a falling, sinusoidal or cosine curve and after passing through the Reversal point is increased according to a sine or cosine curve up to the original traversing speed.
  • This procedure can be operated in such a way that the switching time for the beginning of the sine or cosine change in the traversing speed and its termination is determined as a function of the delivery speed of the sliver. This procedure ensures that sudden braking and acceleration profiles are avoided. At much higher than usual delivery and traversing speeds for flat cans, it is possible to ensure trouble-free sliver placement and to improve the structure of the band column.
  • the constant change in the flat can speed takes place in a defined path range, which extends from the reversal point in the longitudinal direction of the can movement to approximately a deposit radius of a sling.
  • a circular band loop which, in the storage position, touches both side walls or is at least deposited in the immediate vicinity.
  • the drive means can be a servo motor which is controlled by a computer as a control means.
  • the servo motor realizes the sine or cosine change of the traversing speed at a desired time.
  • the drive means is a different, more cost-effective electric motor, but which has arranged belt wheels that can be coupled on its drive shaft. It is characteristic that when the reversing path is reached and left, the undercarriage of the traversing device is uncoupled and coupled from the drive shaft via the belt drive.
  • the belt drive has drivers which engage in the holding means of the chassis and thus enable the chassis to move and change direction.
  • the movement of the flat is detected by a sensor which is arranged at the limit of the reversal path.
  • the sensor can be adjusted and fixed along the reversal path.
  • the traversing device has a carrier plate which has a compression spring arranged and fixed in the center, so that both ends of the compression spring are not fastened and are designed as an impact surface.
  • the compression spring is arranged at the level of the fixed stops for the traverse paths. When the carrier plate moves in the direction of the traversing path stop, one end of the compression spring hits the stop. The compression spring absorbs the kinetic energy and releases it when it expands. In this way, a sinusoidal or cosine motion sequence can be realized in the area of the reversal path.
  • the stop can be adjusted in the distance and re-fixed, i. H. the spring travel of the compression spring is influenced. With different delivery speeds, this option is used to keep the reversal time (time to complete the reversal path) constant. If there is a requirement to keep the reversal path constant for different delivery speeds, this is achieved by exchanging different compression springs.
  • the traversing device has means for gripping and holding the flat can. Furthermore, the flat can is moved in the traversing device on a roller conveyor.
  • the car arrangements for the transport of the flat can, which were customary up to now, are eliminated, which would have unnecessarily increased the moment of inertia.
  • a filling device 1 and the associated flat can 4 are shown schematically.
  • the filling device 1 is usually part of a card or a draw frame.
  • the filling device 1 consists in particular of a stationary turntable 2, which is surrounded by a machine table 3.
  • the turntable 2 rotates and places the sliver supplied in the transport direction F in the Flat can 4.
  • the sliver is placed in one layer over the entire length of the flat pan's can plate.
  • the can plate can be moved in height and, when the flat can is empty, it is positioned below the upper edge of the can. With increasing storage on sliver, the can plate lowers.
  • the sliver is laid down over the entire length of the can plate. For this purpose, the can is moved back and forth in the longitudinal direction.
  • the flat can 4 is shown in an end position.
  • the opposite end position of the flat can 4 is therefore shown by a broken line. Due to this can movement, the turntable 2 can deposit the sliver in cycloids along the entire
  • the flat can is moved between the two end positions along a distance A and moved back along the same distance A '.
  • Each of these sections A or A ' is the traversing section.
  • the traversing distance is the distance between the two reversal points P1 and P2.
  • a back and forth movement is carried out when the can is moved on the traversing path A and the traversing path A '. This process is repeated periodically when filling the can.
  • the return movement is analogous from P2 to the reversal point P1.
  • the traversing path A is thus divided into an acceleration path F2, which changes into a path C, which is essentially characterized by a uniform movement. It cannot be ruled out that there is a movement slightly different from a uniform movement. However, this movement does not affect the function of the invention. It connects to a braking section D1. The situation changes at the reversal point P2.
  • An acceleration distance D2 follows. It is followed by a distance E, which, like the distance C, is characteristic of an essentially uniform movement.
  • a braking section F1 forms the end. Braking and acceleration distances are characteristic of every turning point.
  • the braking and acceleration sections are therefore identified as reversing paths UW1 and UW2. Exceeding the limit of the reversal path UW1 or UW2 is monitored and registered by a sensor S1 or S2.
  • the filling device 1 fills a flat can at a delivery speed that is set as constant. For example, a delivery speed of 800m / min. his. A corresponding traversing speed is set in relation to this delivery speed. This traversing speed is realized on sections C and E and is constant. This speed will be close to the reversal points P1 and P2, i.e. in the area of the reversal paths UW1 and UW2, constantly changing.
  • the constant change in the constant traversing speed is such that the movement of the flat can approaching the reversal point is reduced in accordance with the descending course of a sine or cosine function. The reduction takes place down to the value zero at the reversal point. After passing through the reversal point, the movement is again up to the maximum value according to a sine or cosine curve, i.e. Traversing speed increased. This procedure ensures that there are no sudden braking and acceleration processes.
  • the constant change begins when the reversal path is reached and ends when the reversal path is left.
  • the time for changing the traversing speed in a sinusoidal or cosine curve is determined as a function of the delivery speed of the sliver.
  • different reversal paths are available for changing the traversing speed in length, in order to be able to keep the time (reversal time) required for walking through the reversal path constant.
  • the traversing device 15 is arranged below the filling device 1.
  • the traversing device includes a roller conveyor 6 on which the flat can is at a standstill.
  • the roles are free mobile. You can have the width of the flat jug. However, it is also feasible for two rollers to be arranged side by side, which are only positioned under the lower edge of the side walls.
  • the runway 6 has a length that corresponds to the traversing path.
  • the roller conveyor 6 has the advantage that it is structurally simple, requires little effort and ensures that no additional masses of a can carriage have to be moved when the can is moved.
  • guide rollers 13, 130, 131 are arranged, which keep the flat can 4 in track during longitudinal movement.
  • Analogue guide rollers are arranged on the opposite side (not visible) of the flat can.
  • the traversing device 15 also consists of a rail 5, which is limited by stop bolts 12, 120. The length of the two stop bolts can still be adjusted. The adjustability is necessary in order to be able to operate the traversing device at different delivery speeds.
  • a chassis 9 is arranged to be movable.
  • the chassis 9 is connected to a carrier plate 10.
  • the backing plate 10 carries a compression spring 11 on its back, which is arranged and fixed in the center.
  • the ends of the compression spring 110, 111 are open and designed as an impact surface in relation to the stop bolts 12 and 120.
  • a separate compression spring is arranged on the carrier plate 10, so that each individual compression spring has a spring end as an impact surface.
  • two clamping cylinders 7, 70 are arranged in the center. These clamping cylinders are aligned parallel to the rail 5 and can each pivot a gripper 8 and 80 about its vertical axis. The flat can is positively gripped by the vertical pivoting of the grippers 8 and 80.
  • the grippers 8, 80 are pressed against a stop (not shown), so that the flat can is clamped and held by the grippers 8, 80.
  • the carriage 9 moves the carrier plate 10 and by means of a tensioning cylinder and gripper, the carrier plate 10 transports the can along the roller conveyor 6.
  • the roller conveyor 6 saves the previously usual use of a transport carriage for the flat can.
  • the flat can 4 is moved by the traversing device 15 on the roller conveyor 6.
  • the carrier plate 10 alternately strikes the stop bolt 120 or 12 with the open end of the compression spring 110 or 111.
  • the stop bolt 12, 120 represent the limitation for the traversing path.
  • the flat can 4 is moved at a uniform traversing speed. During this traversing movement, the flat can reaches one of the two reversal paths, for example UW2. Reaching the limit of the reversal path UW2 is detected by sensor S2. The sensor S2 registers the arrival of the incoming end wall. The distance of the two sensors S1 and S2 from the reversal point of the traversing (the reversal points P1, P2 correspond to the stop bolts 12 and 120, respectively) can be adjusted and fixed. The reversal path (UW1, UW2) can thus be set to the desired operating conditions.
  • this sensor S2 When the sensor S2 signals the entry of the flat can into the reversing path UW2, this sensor S2 initiates a signal which uncouples the undercarriage 9 from the drive means 14 with the flat can 4. Due to the inertia, the flat can 4 moves towards the stop pin 120. The corresponding end of the compression spring 110 hits the stop pin 120. The compression spring 110 absorbs the mass acceleration. The compression spring 110 has a selected spring constant and is pressed at the corresponding end. As a result, a sine or cosine reduction in speed is achieved before the reversal point is reached. This reduction in speed corresponds to a movement which takes place when a sine or cosine function is run through from the maximum value of a half-wave to the zero point.
  • the compression spring expands and accelerates the flat can.
  • This movement curve is set up in such a way that it corresponds to the sequence of a sine or cosine function from the zero value until the maximum value of a half wave is reached.
  • the can has returned to its original traversing speed and leaves the reversing range.
  • the chassis 9 and thus the flat can 4 are coupled again to the drive means 14.
  • the drive means 14 ensures a uniform movement of the flat can 4.
  • the drive means is not a servo motor but a cheaper, different electric motor
  • the movement of the can 4 is generated by two belts arranged in a horizontal plane.
  • the drive means 14 on its shaft 20 has two pulleys, pulley 16 and 17. These can be coupled to the shaft 20.
  • the clutch mechanism 200 is indicated.
  • the coupling and uncoupling can be controlled by a known control means, which is not the case here was shown.
  • the control means can be a computer.
  • the coupling takes place in such a way that the two belts 18, 19 are driven alternately.
  • FIG. 3 a shows, the belt 18 is guided by the pulley 16 via deflection pulleys 21, 22 and reversing pulleys 23, 24.
  • the belt 19 is guided in a crossed manner to form belts 18 around the pulley 17 (FIGS. 3a, 3b) and on via deflection pulley 210, reversing pulleys 240, 230 and deflection pulley 220. Both belts are fastened by a common driver (not shown), which in turn is connected to the undercarriage 9 or the carrier plate 10. Since both belts are connected by a common driver, one belt is driven in reciprocal operation, while the other belt inevitably runs without a drive. A belt is always driven over a selected distance between the deflection pulleys 23, 230 to 24, 240, which corresponds to a distance C or E according to FIG. 1.
  • the drive 14 with its shaft 20 maintains a direction of rotation, while the belt wheels 16, 17 are alternately coupled and uncoupled at the times described.
