Definitions

  • the invention relates to the filling of the flat can with sliver by a textile machine delivering sliver, such as a card or draw frame, the flat can being moved under a stationary rotating turntable.
  • the movement of the can has an influence on the quality of the sliver laid down and on the degree of filling of the can.
  • flat cans are filled by rotating a turntable as a delivery device, and the flat can is moved back and forth under this turntable, i.e. the flat can is changed. While the flat can is being moved, its speed is matched to the delivery speed of the sliver. The back and forth movements of the flat can take place at a constant speed up to the turning point. During this movement, the flat can has a flat position with its base.
  • EP 457 099, column 4, lines 26-33 In order to achieve a higher degree of can filling with a defined quality of the sliver to be laid down, it was proposed in the prior art (cf. EP 457 099, column 4, lines 26-33) to combine the straight-line traversing movement with a lateral movement of the flat can to this end .
  • EP 457 099, column 12, 35.-39. Line assumes that the lateral, translational transverse displacement of the flat can can result in an increase in the degree of filling by shifting the loop storage of the sliver. This fact is important because the can also serves as a buffer store between the draw frame and the rotor spinning machine, reducing the number of times it is transported as the degree of filling increases.
  • EP 457 099, column 4, 26.-31 In order to achieve a higher degree of can filling with a defined quality of the sliver to be laid down, it was proposed in the prior art (cf. EP 457 099, column 4, lines 26-3
  • the document (EP 457 099, column 12, lines 39-42) does not provide any information, but according to the prior art, rail-guided scales (DE-OS 19 23 621) are possible for the flat can both to change and to enable the associated lateral transverse displacement.
  • DE-OS 19 32 621 describes that the transverse displacement is carried out by two independently guided transport devices (superstructure and undercarriage). The long can is on the uppercarriage. The directions of movement between the undercarriage and the uppercarriage are arranged so that they can be perpendicular to each other. The undercarriage realizes the traversing movement and the superstructure realizes the straight, lateral transverse displacement of the flat can. The document describes superimposing both directions of movement so that a resulting direction of movement follows.
  • the object of the invention is to reduce the effort required for filling a flat can in terms of effort compared to the prior art.
  • a textile machine delivering sliver can be a card or a draw frame.
  • the delivery device is a stationary turntable which, due to its rotation, deposits the sliver in a cycloid-like manner in the flat can.
  • the flat can is moved below the turntable for filling.
  • the method according to the invention for traversing a flat can during the filling process on a textile machine delivering sliver is realized in that the flat can is laterally displaced in the reversal path of the traversing by pivoting the flat can about an axis.
  • the reversal path of the traversing is part of the traversing path.
  • the traversing path is the path between two reversal points. If the flat can moves to a reversal point, the flat can is braked in the immediate vicinity of the reversal point and accelerated for a short distance immediately after passing through the reversal point. These distances of braking and accelerating in the immediate vicinity of the turning point are called the turning path.
  • the movement of the flat can between the two reversing paths is an essentially uniform movement.
  • the flat is pivoted from one side to the other around a defined axis.
  • the flat can is pivoted in the reverse path by such an angular amount that the upper edge of the can, which is formed by the bead, is laterally offset.
  • This offset of the upper can rim is essential for the process, because the sliver loops are always deposited in the area of this upper can rim.
  • the shelf, which is formed between the upper edge of the can, is moved laterally by the swiveling. This makes it possible that the tape storage can be stored laterally offset to the original position (basic position) of the flat can by the turntable.
  • This lateral offset is adjustable and corresponds approximately to the thickness of the sliver to be processed. When swiveling, the flat can leaves its basic position.
  • the basic position is characterized in that the storage surface of the flat can is parallel to the base of the flat can.
  • the flat can is changed to the opposite reversal path.
  • the angle of the pivoting with respect to its basic position, which is assumed by the flat can, is reversed with respect to the basic position when the opposite reversing path is reached.
  • the flat can swivels in the other direction around the axis and in this swiveled position it is in turn swung to the opposite reversal path.
  • An advantage of the invention is that the pivoting movement as a lateral transverse displacement of the flat can is more economical than the known translatory transverse displacement from the point of view of technical complexity. The effort was noticeably reduced. A further advantage is that the inertial forces, which adversely affect the filling process, in particular when the traversing device is reversed, are also compensated for much more cheaply.
  • the angular amount by which the flat can can be pivoted can be set according to the method. The flat can is usually pivoted to the one and the other side by an equal angle. This angular amount is variable and adjustable. This is useful when changing the sliver material as a result of changing lots.
  • Another advantage is to influence possible influences on the sliver storage, which result from the interaction between the storage direction of the sliver and the direction of movement of the elongated side wall. It is an additional advantage that unequal angles can be set for panning, i.e. the angular amount of panning to one side is unequal to the angular amount of panning to the other side. This makes it possible to compensate for deviations from the center between the flat can and the turntable.
  • the traversing device is equipped with a swivel device.
  • the swivel device has swivel sensors as an operating means and an axis about which the flat can is swiveled.
  • the swivel sensors are arranged on both sides of the traversing path of a flat can.
  • the arrangement is such that the swivel transmitter on both sides in the vicinity of the longitudinal walls of a flat can are arranged.
  • one swivel encoder can be arranged in a position relative to the longitudinal wall, which can be located between the upper can edge and the adjacent gripper plate of the traversing device or the lower can edge and the adjacent gripper plate.
  • the arrangement of the swivel sensors for the longitudinal wall of the flat can can also depend on the selection of the swivel axis.
  • the swivel encoders enable swiveling around an axis, the swivel axis.
  • the swivel encoders give the force to swivel and the direction of force to the flat can.
  • the swivel encoders can advantageously be arranged with respect to one another in a horizontal plane.
  • the swivel encoders give the flat can a guide at the same time as it shifts. If the flat can reaches a reversal point of its traversing path during traversing, then both swivel encoders swivel the flat can by a defined angle in a defined direction.
  • the flat jug is held in this position and guided back to the other reversal point when traversing. When the other reversal point is reached, the swivel encoders swivel the flat can into the opposite angular position. This process is repeated until the jug is full and a jug change is indicated.
  • the flat can be pivoted in a traversing device by the pivoting device.
  • the flat can also be pivoted on a transport path that supports the traversing, or the flat can and associated transport path are pivoted together.
  • the flat can is pivoted on a transport path.
  • the transport track is used to guide the movement of the flat can in the reverse path to support the pivoting of the flat can.
  • the flat can is held by the traversing device and moved on the transport path.
  • the traversing device has gripper arms at the ends of which gripper plates are located.
  • the traversing device holds the flat can between the gripper plates.
  • the swivel axis is formed by mounting the gripper plates in the gripper arms.
  • the device transport path has the advantage that it is fixed and supports both the function of the back and forth movement of the flat can and the function of the pivoting movement, whereby pivoting of the transport path or an additional can transport means are avoided.
  • This advantage is achieved in particular in that the lower can edge (formed by the can bulge) is moved on rollers which are lowered with respect to one another with their axis of rotation.
  • This roller arrangement enables the flat can to be both shifted and pivoted on the transport path. Swiveling on the conveyor belt is possible because the lower edge of the can can slide up and down on the inclined rollers.
  • a swivel encoder this is designed as an eccentrically mounted roller.
  • the roller is rotatably mounted in its eccentric axis of rotation.
  • the roller can also be swiveled and fixed continuously around its eccentric axis of rotation.
  • the flat can is guided between the two eccentrically mounted rollers.
  • the rollers can be arranged in the lower or upper can area. By simultaneously pivoting both rollers through a common angle and in a common direction, the flat can is pivoted about its pivot axis.
  • the design of the swivel encoder as eccentrically mounted rollers is particularly advantageous because there is very little structural effort for swiveling.
  • the rollers also achieve advantageous guidance of the flat can during the traversing.
  • An adjustment device controls the movement of the two rollers depending on the reversal points.
  • the swivel encoder is a sliding bar.
  • the sliding bars arranged on both sides in the vicinity of the longitudinal wall of the flat can be handled independently of one another, yet their interaction can be synchronized.
  • the angle of the swivel is via the control of the swivel encoder adjustable.
  • the swivel encoders additionally allow the flat can to be centered in a basic position, which is advantageous for changing the can, and to precisely guide the flat can when it is being moved in the pivoted position.
  • FIG. 2a and 2b illustrate the pivoting of the flat can.
  • the end face of a flat can is shown in FIG.
  • the end face 5 can be seen, which is delimited by the side surfaces 2 and 3 and partly by the upper can bead 9 and the lower can bead 8.
  • the flat can 1 stands with its base 7 on the base area 6.
  • FIG. 2 facilitates the understanding of a basic position G of the flat can to be defined.
  • a flat can is also in the basic position if the base 7 is arranged above and parallel to the base 6.
  • FIG. 2 also shows a central perpendicular M which lies in the middle between the side walls 2 and 3, runs parallel to the latter and is perpendicular to the standing surface 7.
  • the axis A0, about which the can 1 is to be pivoted, is a longitudinal axis which is perpendicular to the perpendicular perpendicular M, but below the standing surface 7.
  • This state according to FIG. 2 is the basic position G of the flat can 1.
  • the flat can becomes pivoted into a state shown in Figure 2a or Figure 2b.
  • the flat can starts in the reverse path. It is pivoted within this reversal path by an angle ⁇ to the left about the axis A0.
  • the angle ⁇ is created by pivoting a flat can with a perpendicular M relative to the perpendicular L of a base area 6.
  • the upper edge of the can which is formed by the bead 9, is laterally offset. This lateral offset of the upper edge of the can is essential because this leads to a lateral offset of the storage surface 10.
  • the variability and adjustability of the angles ⁇ and ⁇ means that the placement of the sliver loops can be varied with respect to the lateral edge of the can.
  • the flat can is held in this pivoted posture according to FIG. 2a and oscillates up to the opposite reversal path.
  • the flat can 1 is pivoted in the opposite direction with respect to the perpendicular L.
  • Figure 2b shows this state.
  • the flat can 1 with a perpendicular M was pivoted back by the amount ⁇ and moreover pivoted in the opposite direction by the angle ⁇ .
  • the flat can is held in this pivoted position (FIG. 2b) and oscillates when the reversal path is left.
  • the flat can is changed in the swiveled position. This corresponds to a lateral displacement of the top edge of the flat can relative to the traversing direction. With the lateral displacement of the flat can by pivoting it is achieved that the slings can be stored offset from the layer of slings already directly below.
  • the flat can is advantageously pivoted by an angle which corresponds to the displacement of the flat can by approximately the thickness of a sliver to be processed. It has been found that this angle between perpendicular M and perpendicular L can be in the range of about 2 °.
  • the swiveling of the flat can to one side and later to the other can take place at the same angular amount, ie the angles ⁇ and ⁇ are equal in amount, but opposite in the direction with respect to the perpendicular L.
  • the angular amount is variable and adjustable.
  • the upper can rim 500 of a flat can is shown schematically.
  • a turntable 600 is assigned.
  • the flat can has a traversing speed with the direction of movement K.
  • the turntable 600 has a rotational speed and a direction of rotation DR, with rotational forces R1, R2 occurring on the circumference influencing the sliver to be laid down. It is also influenced by the movement of the flat can.
  • the sliver deposited from the turntable 600 into the flat can with the top edge 500 of the can receives a relative speed.
  • the speed components of the turntable and the flat can act in the opposite direction near the wall 500.
  • the result is a lower relative speed of the sliver in this area.
  • the storage radius for the sliver increases, i.e. the sliver will be deposited slightly more towards the edge of the can.
  • This effect can be taken into account due to the variability and adjustability of the angle for pivoting the flat can, i.e. the angle to be set for pivoting can be somewhat smaller than originally without taking the described effect into account, provided the can rim 500 is pivoted to accommodate the fiber sliver drifting outwards at this point.
  • the can rim is thus not pivoted into position 500 'as originally, but, provided that there is an "oncoming" direction of pivoting RS, only pivoted into the position of the upper can rim 500' ', i.e. the set angle is slightly smaller than the originally intended angle of pivoting.
  • An analogous situation applies to the return movement of the flat can.
  • Figures 3 and 3a show the effect that can be achieved by moving the flat can by swiveling the tape deposit. This effect is the basis for the fact that the degree of filling can be increased significantly compared to cans that are not moved laterally.
  • FIG. 3 schematically shows some sliver loops lying one on top of the other during a traversal movement without lateral displacement of the flat can. It can be seen that the sliver is arranged on the elongated side walls 2, 3 one above the other. In contrast to this, FIG. 3a shows the state of the sliver when traversing with transverse displacement. It can be seen that the fiber sliver is laterally offset from the fiber sliver located below or immediately above it. The offset corresponds approximately to the thickness of a sliver. With this type of storage, the filling level of the flat can can be increased by up to 30% depending on the fiber material.
  • the position of the axis around which the flat can is pivoted is very important for pivoting the flat can.
  • Some possibilities for the position of the pivot axis are shown schematically in FIG.
  • the axis A2 is centrally symmetrical.
  • Another embodiment is the axis A1 lying underneath, which lies in the base of the flat can.
  • the swivel axis A0 is even lower and therefore outside the flat can. This case is already shown in Figure 2.
  • the axis A3 shows the possibility that the flat can can also be pivoted about an axis which is outside the flat can and near a side wall. These possibilities shown have in common that the axis about which the can is pivoted is parallel to the traversing direction CR.
  • the axis can also be in a position that does not lead parallel to the traversing direction CR.
  • FIGS. 5 and 6 show schematically in FIGS. 5 and 6.
  • Figure 5 shows the position of the A4 axis.
  • This axis A4 lies in the footprint 7 of the flat can 1 from a corner to the diagonally opposite corner of the flat can.
  • This position of the A4 axis is advantageous since the inertia can be used here favorably.
  • In the reverse path of each traverse there is a short stretch of line where the can is accelerated against its original speed. This creates an inertial force of the can center of gravity in the opposite direction, which can be used as a driving force for pivoting the flat can.
  • FIG. 6 shows the possibility of also being able to guide the axis vertically for pivoting the flat can.
  • the axis A7 is a vertically arranged central axis around which the flat can can be pivoted.
  • the vertically guided axis can also be guided outside the flat can, advantageously in the vicinity of the end wall. Swiveling around one of these axes also results in an offset of the sliver during the filing.
  • FIGS. 7 and 7a A basic structure of a device for traversing a flat can according to the invention during the filling process is shown in FIGS. 7 and 7a.
  • a flat can 1 hangs under the turntable 22 of a section 23. One of the end walls of the flat can can can be seen.
  • the section delivers the sliver to the turntable 22, which deposits the sliver (not shown here for reasons of clarity) in the flat can 1.
  • the traversing device 16 detects the flat can 1, each with a gripper arm and its pivotable gripper plate on the end wall.
  • Figure 7a shows a view of the longitudinal walls of the flat can. It can be seen more clearly there that the flat can 1 is clamped and held between the gripper plates 18, 18 '. A condition for changing the can is shown.
  • the gripper plates 18, 18 ' are pivotable and resettable in their gripper arms 17, 17'. This bearing corresponds to a swivel axis, axis A2.
  • the gripper arm 17 can be arranged, for example, in the traversing device 16 so as to be pivotable about a vertical axis 170, so that it can be pivoted through 90 ° from an initial position (parallel to the rail 160 FIG. 7a) for gripping and holding the flat can (FIG. 7).
  • the gripper arm 17 ' is strongly fixed in the gripping and holding position, i.e. the gripper arm 17 'forms a stop for the new flat can to be inserted when the can is changed. This has the advantage that the flat can is thus positioned opposite the traversing device.
  • the flat can 1 is held and oscillated by the traversing device 16.
  • the traversing takes place along a rail 160, which corresponds to a traversing path with the reversal points.
  • an upper can area oKB and a lower can area uKB are shown on both sides.
  • the upper can area oKB is an area between the upper edge of the can and a gripper plate holding the flat can lies.
  • the lower can area oKB is an area that lies between the lower edge of the can and a gripper plate holding the flat can.
  • the swivel sensors S1, S2 can optionally be arranged for these can areas.
  • the swivel sensors S1, S2 can be arranged in the upper can area oKB.
  • FIG. 7 shows a possible arrangement of the swivel sensors S1 and S2 in the lower can area uKB.
  • the swiveling device SV is formed by swiveling sensors S1, S2 and the axis A2. This swivel device SV is arranged with the traversing device 16.
  • the swivel sensors S1, S2 are arranged in the vicinity of the lower can bead 8. In the basic state, the rotary encoders S1, S2 have no contact with the flat can 1. Before the oscillation begins, the rotary encoders S1, S2 are put into operation, i.e. they give the flat can a guide in the lower area uKB. The swivel sensors S1, S2 thus have the option of centering the flat can in the basic position or swiveling it into a swiveled position and giving guidance in this swiveled position.
  • the swivel sensors S1, S2 are activated in accordance with FIG. 7, so that they swivel the flat can in the lower region to the right or left around the axis A2 and, in one of these swivel positions, lead to the opposite reversal path when traversing.
  • the flat can 1 is returned to its basic position G, i.e. it hangs and can be transported on a prepared can magazine trolley (not shown). An empty jug is hung from the jug magazine trolley into the basic position G below the turntable 22.
  • the flat can 1 stands on a transport path 19.
  • the transport path 19 is designed in such a way that it can ensure both the traversing movement and the pivoting movement of the flat can 1.
  • the contact surface 190 of the transport path 19 is designed to be concave.
  • the concave contact surface has its apex line at the lowest level. Because of this concave design of the contact surface 190, the flat can stands on both sides with the lower can bulge 8 of the elongated side walls on the contact surface 190.
  • This has the advantage that the contact surface 190 enables both a changeable and a pivoting movement of the flat can without additional design effort.
  • the transport track 19 therefore also does not require any portable assemblies such as push cars to carry out the pivoting movement of the flat can.
  • FIG 9 shows a detailed embodiment of the swivel device with a transport path.

  • There is a switch in the reversal path of the traversing (not here shown), which guides the flat can from one rail path 403, 404 to the other rail path 403, 405 and vice versa.
  • the flat can is thus forcibly guided on the angled walls 401, 402 of the transport track 40.
  • FIG. 14 shows a further advantageous embodiment of a swivel encoder SG.
  • the swivel encoder SG consists of a roller 50 which is mounted eccentrically in an axis 51.
  • FIG. 14 shows, for example, that roller 50 with axis 51 is arranged beneath the machine table 52 of the sliver storage of a stretch.
  • a flat can 1 for traversing is arranged under the machine table 52.
  • the swivel encoder SG consists of adjusting lever 53 with axis 54 and an adjusting device 55. Adjusting lever 53 with axis 54 and adjusting device 55 are arranged above the machine table 52 and do not interfere with the movement of a flat can.
  • the roller 50 consists in detail of an eccentric hub 56 which is arranged eccentrically in axis 51.
  • the eccentric hub 56 is fixedly connected to the axle 51 by a detachable screw connection.
  • the eccentric hub 56 has an elongated hole 57 with an adjustable grid. With oblong hole 57 there is the possibility of making the eccentricity of the eccentric hub 56 gradually adjustable and fixable. An adjustment of the eccentricity may be necessary, for example, if changed can formats or a change in the swivel angle are necessary.
  • the eccentric hub 56 has a ball bearing ring 58.
  • a roller ring 59 with its outer surface 60 is rotatably arranged on this ball bearing ring.
  • the axis 51 is fixed to an adjusting lever 53.
  • the adjusting lever 53 is rotatably mounted in the axis 54.
  • the adjusting device 55 is mounted in the axis 54.
  • the adjusting device 55 can be designed, for example, as a pneumatic cylinder 61 with a piston rod 62. However, other physically acting adjusting devices could also be used, for example electromechanically or hydraulically acting adjusting devices.
  • the piston rod 62 is in engagement with the axis 54.
  • the pneumatic cylinder 61 is held by an angular body 63 which is fastened on the machine table 52.
  • the pneumatic cylinder 61 also has a connection 64 for a control line, which leads to a control device.
  • the swivel encoder SG is arranged on both sides of the traversing path of a flat can, preferably on the reversing path. The arrangement can optionally take place in the vicinity of the lower can area or the upper can area. According to FIG. 14, the arrangement of the swivel transmitter SG in the vicinity of the upper can area oKB is shown, for example.
  • FIG. 16 shows a plan view of the swivel transmitter SG according to FIG. 14.
  • FIG. 16 shows that roller 50 can be swiveled and adjusted between the position shown and the dashed position P. For this purpose, the piston rod 62 must be pulled or pushed.
  • FIG. 15 shows a flat jug that is empty and is placed in the changing position when the jug is changed.
  • FIGS. 15 to 15b show an illustration with a view from the lower side of the machine table 52 onto the storage surface 10 of a flat can with an upper can edge 9.
  • the two rollers 50, 50 'with their eccentric axis 51, 51' are arranged schematically in the upper can area, at the upper edge 9.
  • the flat can is already in the change position and the rollers 50, 50 'are placed on the upper edge of the can by means of an adjusting device.
  • the outer surface 60 of the roller ring 59 lies against the can rim 9.
  • the preparation for a traversing position of the flat can is shown in FIG. 15a.
  • the dashed arrangement shows comparatively the state of FIG. 15. In comparison to FIG. 15 of FIG.
  • the eccentrically mounted rollers 50, 50 ' are pivoted together about their axes 51, 51' in the R direction by a defined amount.
  • This pivoting of the roller 50 is realized, for example, with a push of the piston rod 62.
  • the adjusting lever 53 rotates the eccentric hub via axis 51 56.
  • the pivoting for roller 50 ' is realized.
  • the result is a swiveling of the can 1 in the direction R about an axis A2 shown.
  • the traversing of the flat can begins and the rotating turntable deposits the sliver in a cycloidal shape.
  • the flat can is oscillated up to the reversal point of the traversing path.
  • the SG rotary encoder can also be used in the lower can area uKB.
  • the SG rotary encoder requires little design effort, is inexpensive and requires little maintenance.
