Definitions

  • the invention relates to a device for pivoting a reciprocating flat can on a textile machine delivering sliver during filling with sliver.
  • the flat can In the reversal points of a traversing path, the flat can is pivoted about a pivot axis by a pivoting device. The pivoting takes place transversely to the traversing path, the flat can being pivoted in a transverse direction and being pivoted in this pivoted position.
  • the flat can is swung back in the opposite transverse direction while crossing the traversing path and is now oscillated in this position.
  • the German application P 43 24 951.5 shows a swiveling device in cooperation with a traversing device, the flat can being given a swiveling force in the lower can area by the swiveling device.
  • the traversing device according to P 43 24 951.5 has a transport path on which a flat can can be traversed.
  • the transport path is designed so that it can also ensure the pivoting movement of the flat can.
  • Sliding bars are arranged on both sides of the transport track. When traversing are the sliding bars with their roles on the flat can.
  • the sliding beams are controlled so that they exert a thrust across the traversing path in the reversal points of the traversing path.
  • the flat can is moved laterally to the next reversal point and then laterally again in the opposite direction. This pushing device is complex due to the sliding bar and expensive.
  • the object of the invention is to arrange a device for pivoting a flat can, which requires considerably less effort and is less expensive.
  • a swivel device is arranged in relation to the flat can at the level of the upper can area.
  • the can area is an area that lies between the upper edge of the can and a gripper plate that grips the flat can by means of a gripper device.
  • the pivoting device acts in this area and is preferably arranged there.
  • the swivel device has two swivel encoders as work equipment.
  • the swivel sensors are arranged in the vicinity of the upper can area on both sides of the flat can. In an advantageous embodiment, they are arranged on the lower machine table opposite one another with respect to a turntable.
  • the swivel encoders not only give the flat can in the upper can area the swiveling movement, but at the same time guide it during traversing. If the flat can reaches a reversal point of its traversing path, then both swivel encoders pivot the flat can transversely to the traversing path. The Flat can is thus pivoted about its pivot axis at a fixed angle. In this position the flat jug oscillates back to the other turning point. When the other reversal point is reached, the swivel encoders swivel the flat can over the traversing path in the opposite transverse direction. This process is repeated until the jug is full and a jug change is indicated.
  • the swivel encoders are preferably designed as rollers which have an eccentric axis.
  • the rollers are arranged opposite one another with respect to a turntable on the underside of the machine table. By simultaneously rotating both rollers with their eccentric axis according to a defined angle, the flat can is pivoted about its pivot axis.
  • the rotational movement of a roller is achieved by a controllable cylinder which is in engagement with an adjusting lever for the roller.
  • the control enables a stroke or pull of the piston rod of a cylinder, so that the roller can be rotated through a necessary angle with its eccentric axis.
  • the outer surface of a roller is rotatable relative to the base body of the roller.
  • the flat can Since the roller lies against the can wall, the flat can is pivoted transversely to the traversing path by rotating the roller.
  • the design of the swivel transmitter as rollers is particularly advantageous because there is an extremely low structural outlay for generating a swivel movement and, at the same time, the rollers ensure an advantageous guidance of the flat can during traversing. This type of guidance is advantageously low-friction.
  • Another advantage is that, for example, when the flat can is moved on a Transport path, the transport path located on the ground is clear of a swivel device and thus there is better accessibility for a transport system when changing the can.
  • Figure 1 shows the storage device 1 of a stretch of the textile industry.
  • a carding device is also applicable, the essentials of which are described below with reference to the route.
  • Both are textile machines that deliver sliver.
  • a turntable 2 with a band guide channel is rotatable 3 arranged.
  • a pair of calender rolls 10, 10 ' is located above the belt guide channel 3.
  • the pair of calender rolls 10, 10 ' when filling a flat can, feeds sliver FB into the sliver guide channel 3 of a turntable 2, which deposits this sliver in a cycloidal shape in a flat can 5. While the sliver FB is being deposited, the flat can 5 is oscillated on the traversing path AB.
  • the jug is gripped by a gripping device.
  • the jug is therefore arranged between the gripper plates 6, 8, which are part of a gripping device.
  • the gripper plate 6 is rotatably mounted with the axis 17 in a gripper arm 7.
  • the gripper plate 8 is rotatably mounted in the gripper arm 9 with the axis 17 '.
  • Gripper arms 7, 9 with gripper plates 6, 8 oscillate the flat can 5 along a rail 12 with a stop.
  • the stop of the rail 12 corresponds in each case to the reversal points A or B of the traversing path A B.
  • the flat can 5 can be traversed freely hanging or it can be traversed standing on a transport path.
  • FIG. 2 shows a side view of FIG. 1, it becoming apparent that the traversing device 11 has a traversing carriage 16 which is arranged to be movable on the rail 12.
  • the traversing carriage 16 has gripper arms.
  • a side view of a gripper arm 9 with a gripper plate 8 is shown.
  • a swivel device 15 is arranged in the upper can area.
  • the swivel device 15 has swivel sensors 13, 14 as the working means.
  • the swivel sensors are arranged on both sides in the upper can region. In order to keep the number of swivel sensors necessary, with regard to an arrangement of 2 swivel sensors in the upper can area, these are advantageously arranged in the vicinity of the turntable with regard to their arrangement on the underside of the machine table.
  • the upper can area 19 is delimited by the upper can edge 18 and the gripper plates 6, 8 holding the flat can.
  • the swivel device 15 with the swivel sensors 13, 14 is optionally arranged.
  • an arrangement of the swivel device in a lower can area is also possible.
  • a lower can area should be defined in the same way as the upper one. However, this is less advantageous.
  • An arrangement in the upper can region 19 is more advantageous because obstruction with a transport system for the can operating in the lower can region is avoided. This transport system is not shown for reasons of clarity.
  • the pivot sensors 13, 14 can advantageously be arranged on the underside of the machine table 4.
  • the swivel encoders are guided by a control device 100.
  • the control device 100 causes through its program that at the reversal point of the traversing path both swivel encoders simultaneously pivot in a common direction transverse to the traversing path. This is how the flat jug is swiveled. Reaching a reversal point A or B is reported to the control device 100 by sensors 101, 102, which are each arranged at the reversal point A or B. When the can reaches its other point of reversal, the swivel sensors pivot the flat can about the pivot axis 17, 17 'in the opposite direction transverse to the traversing path.
  • each individual swivel encoder is equipped with a controllable drive.
  • the operation of this swivel encoder is shown schematically in Figures 4 to 4b.
  • the illustrations show a top view of the flat can 5, viewed from the underside of the machine table 4.
  • the turntable, which is arranged in the machine table 4 is shown schematically in FIG.
  • FIG. 4 shows a basic position of the flat can 5.
  • an empty can supplied by the transport system is positioned before the filling process begins.
  • the pivot axis 22 is symmetrical to the side walls of the flat can 5.
  • the pivot device 15 is arranged in the upper can region 19.
  • the top view shows that swivel sensors 13, 14 are arranged on both sides of the can wall.
  • the swivel encoders are rollers which are each connected to an eccentrically mounted axis 20, 21.
  • Other equivalent means of role can also be used.
  • These axes of rotation 20, 21 can, for example, be fastened to the underside of the machine table 4 and thus project perpendicularly into the image plane of FIG. 4.
  • the turntable 2 is arranged in the machine table 4 between the swivel encoders 13, 14, but in one plane with the machine table. For reasons of clarity, the turntable 2 is not shown in FIGS. 4a, 4b.
  • Figure 4a shows a pivoting of the flat can 5 after the flat can has reached a turning point (not shown).
  • the end face facing away from a turning point with partial side wall is shown.
  • the flat can 5 is pivoted to the right R about the axes 20, 21 by rotating the swivel sensors 13, 14 designed as rollers.
  • Figure 4b shows the process when the other reversal point is reached.
  • the swivel encoders 13, 14, which are designed as rollers, rotate in the other direction compared to Fig. 4a.
  • the flat can 5 is pivoted about the pivot axis 22 to the left L.
  • the pivot axis 22 from FIGS. 4 to 4b corresponds to the pivot axis 17, 17 'according to FIGS. 1 and 2.
  • FIG. 5 shows a possible embodiment of a swivel encoder.
  • a pivot encoder 13, 14 can be designed, for example, as a roller 23.
  • the roller 23 has an eccentrically arranged axis 27.
  • An adjusting lever 24 is rotatably arranged in this axis.
  • the adjusting lever 24 is engaged by means of the axis 25 with an adjusting device, which can be a pneumatic cylinder 26, for example.
  • the roller 23 is designed so that when the piston rod 30 of the cylinder 26 is pushed or pulled, the adjusting lever 24 can adjust the roller 23 between its position shown and the roller 23 'position. Thrust or pull of the piston rod 30 is caused by the control device 100, which is connected via connecting lines 103, 104.
  • the outer surface of the roller 23 is rotatable relative to the base body of the roller.
  • the base body is connected to the axis.
  • Each cylinder 26 is actuated by the control device 100, which in turn receives its signal from one of the sensors 101, 102, which report the arrival of the can at the reversal point A or B.
  • FIG. 6 schematically shows the structure of an individual roller 23. The view is directed towards the roller 23 towards the underside of the machine table 4.
  • the roller 23 has an outer surface 230, which is formed by a ring 232.
  • the ring 232 is opposed by means of ball bearings 108 the base body 231 rotatable.
  • the base body 232 is formed by a hub 233 with an elongated hole 106 and a corresponding cover plate 105, which likewise does not cover the elongated hole 106.
  • the cover plate 105 is fastened to the hub 233 by means of screw connection 107.
  • This basic body 231 described is arranged in the axis 27.
  • the base body 231 can be displaced and fixed in the elongated hole 106 by means of screw connection 234 in accordance with the measuring scale 109. The degree of eccentricity of the roller 23 with respect to the axis 27 can thus be adjusted.
  • FIG. 7 shows, in particular, the roller 23 according to section AB from FIG. 6.
  • the adjustability of the eccentricity of the roller 23 by shifting the roller in the elongated hole 106 can be seen.
  • the rotatability of the outer surface 230 of the ring 232 relative to the fixed base body 231 can also be seen.
  • the rotation emanating from the adjusting lever 24 is transmitted to the axle 27 and ultimately to the roller 23. This enables the roller 23 to be pivoted through a desired angle.
