Definitions

  • the invention relates to a winding device for winding threads in spinning systems for man-made fibers.
  • DE-AS 2 438 364 describes a device by which piecing, i.e. the start-up of the spinning and winding process is automated.
  • piecing i.e. the start-up of the spinning and winding process is automated.
  • a winding machine is described there, in which two alternatingly operated winding spindles are mounted on a common bobbin turret.
  • the lossless spool change by means of such a winding device, which has two spindles rotatably mounted on a spool turret, z. B. described in DE-OS 3 211 603.
  • Such winding devices allow a completely automated bobbin change at any time.
  • the bobbin change is essentially lossless, i.e. there is no waste even in the intervals of changing the bobbin.
  • winding devices with two winding spindles are more expensive than those with only one winding spindle.
  • This disadvantage is offset by the avoidance of waste production, which is particularly important for thick threads that require frequent bobbin changes, and by the avoidance of manual operation, which is particularly important when day and night operation with minimal personnel expenditure is desired is.
  • the object of the invention is, while avoiding the technical outlay for a winding device with two winding spindles mounted on a reel turret, to enable unattended handling of the thread during the bobbin change and to create a winding device which, in all cases where there is a loss of waste production plays a minor role during the bobbin change, such as is the case with fine titers, offers the advantages of a winding device with two winding spindles to be operated alternately with less technical effort.
  • the solution is achieved in that the usually existing and partly hand-guided individual elements of the winding device, which are operated during the bobbin change, in particular the thread catching device, thread separating device, thread suction device and thread application device, in a single device that is on a predetermined path in one automated movement is guided, be united.
  • a catch device a separating device, a suction device and an application device are assigned to each plug-on sleeve of the winding spindle.
  • a first exemplary embodiment of the invention is characterized in that all the functional elements of the thread change, namely catching device, separating device, suction device and feed device, are integrated in a single device, namely the suction tip of the suction device, the suction tip itself being automated in a predetermined movement path Movement is guided.
  • the sequence of movements of the suction tip is controlled in such a way that its movement path begins in a catching position which lies directly in front of the plane in which the traversing triangle is spanned. Starting from this catching position, the movement path - projected onto a normal plane of the winding spindle - partially surrounds the winding device with the traversing device and the winding spindle.
  • the catch position is preferably - seen parallel to the axis of the spindle - in the edge areas of the traversing triangle.
  • the movement path is composed of a movement component parallel to the axis of the winding spindle. This has the effect that the suction tip leads the thread laterally out of the traversing area and, on the one hand, inserts it into the so-called thread reserve device and, on the other hand, into the catching device of the empty tube, generally a circumferential slot (thread catching groove).
  • the last part of the movement path is a movement - parallel to the winding spindle - which penetrates the normal plane of this thread catching groove.
  • spool change in this sense means the handling of the thread during the exchange of the full bobbin for an empty tube.
  • handling the bobbin includes both handling the thread and replacing the full bobbin with an empty one sleeve to understand itself. This exchange can be done by hand. This exchange process is preferably automated by means of a doffer which can be moved along the machine front and a known push-off device which pushes the full bobbins off the bobbin spindle.
  • the doffer is positioned with a holding mandrel in front of the winding spindle and the push-out device located on the winding device pushes the full bobbin (s) onto the holding mandrel.
  • the empty tubes are then pushed onto the winding spindle by a suitable device.
  • Corresponding devices are described, for example, in DE-OS 2 939 675 and 2 945 861 (Bag. 1163, 1167).
  • an air-guiding tube is connected to the spinning shaft and that the trajectory of the suction tip according to this invention is created in such a way that the catching position for piecing begins immediately before the air-guiding tube.
  • the suction tip is attached to a swivel arm, the axis of which - viewed in the direction of travel of the thread - lies above the winding spindle.
  • the trajectory of the suction tip describes a circular arc, within the centering angle of which the traversing device and the winding spindle which has been put into operation and which is provided with an empty tube is located.
  • the swivel axis can sit on the same machine part as the winding spindle or on the same machine part as the traversing device. It must be taken into account here that the winding spindle and traversing device must be able to move relative to one another, so that the traversing device can move away from the winding spindle or vice versa as the bobbin diameter increases.
  • the swivel axis of the swivel arm - viewed in the direction of thread travel - lies below the winding spindle and on the side of the traversing triangle facing away from the winding device or the plane in which the traversing triangle lies.
  • the swivel arm is designed as a telescopic tube, so that the movement path of the suction tip is composed of a translational movement component in addition to the axial component and the circular movement component.
  • the swivel arm is used to achieve the above-mentioned. Movement path also - relative to the winding spindle - movable parallel to the axis and the suction tip consequently performs an axial movement at the beginning and at the end of the application movement.
  • Another exemplary embodiment is characterized in that the complicated sequence of movements of the individual functional elements is resolved and that each functional element is assigned only the motion law that is specific to it and necessary for it.
  • the functional elements are mounted on a support (holder) parallel to the winding spindle.
  • This carrier is movable on its longitudinal axis and perpendicular to it in a vertical plane.
  • the suction device and the separating device are firmly connected to this carrier.
  • the catching devices can perform a relative movement to the carrier (holder).
  • they are attached to a swivel system which is articulated on the carrier (receptacle).
  • the catching devices advantageously also serve as a contact device.
  • two catching devices are provided one below the other. Each consists of a horizontal catch tongue with two parallel edges that is inclined to the vertical plane of the thread.
  • thread trap in the acute angle of each catch tongue to its vertical fastening plane.
  • Such thread traps are known per se and z. B. referred to as wolf teeth.
  • the thread trap allows the thread to penetrate, but prevents it by taking suitable measures, e.g. Protrusions penetrating the thread guide that the thread leaves the thread guide again.
  • the thread, in the traversing triangle of which the thread tongues are inserted gets into the assigned pair of thread traps.
  • the trajectory of the catching device with the thread traps is now predetermined so that the thread running vertically between the thread traps in the inner layer comes to lie exactly in front of the suction tip and in the separating device, which are attached to the carrier.
  • the thread can now be cut off by actuating the separating device, as a result of which it is drawn into the suction tip. Now the running thread is only in the upper thread trap.
  • the carrier can move vertically downwards and then carry out the threading movement by swiveling out the catching device.
  • the running thread is brought into contact with the winding tube, which is assigned to the respective catching device and suction device, and is thereby clamped between the winding tube, the catching device and the suction tip.
  • the advantage of the invention is that, due to the arrangement of the thread suction device on the machine frame, a high suction power can be installed, so that the thread fall can be removed safely and in the required quantities.
  • a complete device for handling the thread during the bobbin change is assigned to the winding device. This device enables any change times for the bobbin change. This in turn creates the ability to operate the winder at any time, i.e. take off the full bobbins and put on empty tubes.
  • Spool take-off carriages in particular have a holding mandrel which can be brought into alignment with the spool and onto which the spools of a spool can be pushed.
  • the bobbin take-off carriage then serves to transport the bobbins to a creel or other take-off point.
  • the sleeve transport trolley has a sleeve magazine and a device with which the empty sleeves are removed from the sleeve magazine and opened the new winding spindle to be put into operation can be pushed on.
  • EP-PS 26 471 describes a winding device in which a bobbin take-off carriage and a thread operating carriage, which also serve to transport the bobbin, are independently movable and operatively connected to each other and to each winding station along the machine front of a plurality of winding stations.
  • spinning machines are also used, in particular for the production of flat, technical threads. in which the freshly spun filament threads are stretched below the spinning shaft by means of a stretching godet arrangement and then wound up at a very high winding speed (spinning stretch winding method).
  • the threads are sucked off from the handling device described at the beginning below the stationary thread guide and, after provision of an empty tube, put back on the winding device, so that the threads do not have to be passed around the possibly several godet units each time the bobbin is changed.
  • the process must be performed regularly when spinning on a spinneret, i.e. in particular after every maintenance of the spinneret and after every winder formation, in particular after capillary breakages that lead to winders on the draw godets.
  • a handling device of this type for applying threads to the stretch godet arrangement of a spinning machine consists of a slide with a thread suction device arranged thereon, the slide being movable in several normal planes of the godet axes between the end of the spinning shaft and the thread guide.
  • the movement of the carriage with the thread suction device begins from the free godet end face in the rear normal plane and leads several times around the respective godet train in the area of each godet unit, a movement from the rear to the next normal plane being superimposed.
  • the threads can be suctioned out below the spinning shaft and can be repeatedly guided around the godet unit by bypassing it.
  • either successive rectilinear movements are preferably carried out, which are repeated with slight axial displacement in the direction of the free end of the godet in parallel planes, or with gimbal attachment of the arm, a circular movement around the godet mechanism is carried out with the thread suction device, which is repeated in axially offset planes, to avoid overwinding the threads.
  • the handling device for laying the threads around the godet works is suspended, for example, from a ceiling construction above the winding machine and can be moved in a plane perpendicular to the winding spindles of the winding device.

  • the carriage is preferably moved via a programmable path control, in particular a microprocessor, which acts on the plurality of drive motors for the carriage.
  • the movement of the carriage with its thread suction device begins at a thread catching position which lies before the mouth of a guide tube connected to the spinning shaft, to which the carriage is returned after the end of the application process.
  • the threads are passed to the suction nozzle of the application device of the winding device after the bypassing of the stretching godets and then cut off, or the movement of the carriage with the thread suction device is programmed so that all thread handling steps up to the application of the Thread on the bobbin tube can be carried out in logical order one after the other.
  • a plurality of empty tubes are plugged tightly onto one another on a winding spindle, so that several traversing devices and other devices are required coaxially with one another.

  • the oscillated thread 10 is guided over the thread guide edges 107 to 107.2 of the thread catchers 102 lying one above the other and slides under thread tension into the respective thread trap 108 formed by inclined pins, wolf teeth and similar thread guides.
  • the angle rail 101 with the thread catchers 102 is activated by actuating the swivel drive 99 pivoted and corrected by simultaneous actuation of the cylinder-piston unit 95 in such a way that the threads 10 lie on their essentially vertical path between two interacting thread catchers 102 in front of the suction tips 18 of the thread suction box 103 and pass the thread cutter 106 (to simplify the Schematic drawing omitted).
  • the carriage 4 is then moved away from the coil surface.
  • the threads 10 are released from the traversing thread guides 8 and the grooved roller 9, and a binding bead is wound on each bobbin 19 in the normal planes of the winding spindle 2, in which the thread traps 108 of the thread catchers 102 are.
  • the winding spindle 2 is already braking.
  • the thread cutters 106 are actuated and the threads 10, which are still delivered, are gripped and sucked off by the suction tips 18 of the thread suction 103.
  • the threads are prevented from falling into the traversing plane between the stationary thread guide 11 in the tip of the traversing triangle and the traversing thread guide 8 .
  • the cylinder-piston unit 95 is acted on, so that the thread catchers 102 move axially parallel to the winding spindle 2, and the threads 10 are caught and wound up by conventional thread catching notches on the empty tubes or the like.
  • the threads 10 running to the suction tips 18 are then torn off one after the other, the formation of a thread reserve on each empty tube by actuation of the device 114 and the catching of the threads 10 by the self-catching traversing thread guides 8.
  • the drives 99 and 92 become in the Operated in the sense that the thread changing device is brought back into the waiting position according to FIG. 19 a, in which the angle rail 101 with the thread catchers is however pivoted back and is in contact with the thread suction box 103.
  • the proper traversing of the threads 10 begins as soon as the device 114 for forming the thread reserve has moved back to its starting position and the self-catching traversing thread guides 8 have gripped the threads.
  • FIG. 20 schematically illustrates the mutual association of the spinning machine 130 with the individual winding stations 160 of the spinning machine 130 associated microprocessor 122, the sleeve transport carriage 126, the bobbin removal carriage 131 and the gate 132.
  • the sleeve transport carriage 126 and the bobbin removal carriage 131 can be operated independently of one another and are connected to the microprocessor 122 by trailing lines 127 and 128, respectively.
  • the microprocessor 122 is connected by lines 129 to the individual winding devices 160 and the devices for thread handling associated therewith, so that the microprocessor takes over the central control of the winding devices 160, thread handling devices according to this invention, the tube transport carriage 126 and the bobbin take-off carriage 131.
  • the gate 132 can be positioned anywhere along the rail run 121. By separating the thread control function on the one hand and the bobbin take-off function on the other hand - as in EP-PS 26 471 - the bobbin take-off carriage 131 is free to transfer the bobbins from the individual bobbins 160 to the gate 132 without the thread control being handled by the devices according to the invention the thread is obstructed.
  • the bobbin removal carriage 131 can be moved on rails 121. It has a column 134 on its base plate, on which the carriage 135 can be moved. A boom 136 sits on the slide 135, on which a cat 137 can be moved. The cat 137 has a pivot axis 138 parallel to the column 134, on which the sliding block 144 is seated. In the sliding block 144, the U-shaped support arm 139 with the holding mandrel 140 is movable in the plane of the U.
  • the corresponding drive devices are not shown in detail here. However, it can be seen from the illustration that the holding mandrel 140 can be moved in height, can be moved in the direction of the arm 136 and in the plane of the holding mandrel 140 and can also carry out a pivoting movement.
  • FIG. 21 a shows the spools 143 and full spools 141 of two winding heads with push-out devices 142 that are still on the chucks (winding spindles) 119 and are still in the winding travel.
  • the holding mandrel 140 of the bobbin removal carriage 131 is positioned in alignment with the winding spindle. Now the U-shaped support arm 139 is moved in the sliding block 144 until the holding mandrel comes almost into contact with the end face of the Spuispindei 119 (movement 157). The push-out device 142 is then started with movement 158 - as can be seen in FIG. 21 a.
  • the holding mandrel 140 is preferably equipped on its front end face with a light source and a photo cell, while the end face of the chuck 119 has a series of light-reflecting foils or plates on its circumference.
  • the rotation of the winding spindle 119 therefore generates a series of pulses which is evaluated in the microprocessor 122 in such a way that the microprocessor can record the nominal speed of the chuck 119, the braking phase, the acceleration phase and the standstill of the winding spindle.
  • the ejection device 142 is started by the signal of the microprocessor 122, which represents the standstill of the winding spindle 119. Since the push-out device engages behind the sleeves of the full bobbins, the two full bobbins 141 are pushed onto the mandrel 140 of the bobbin removal carriage 131. Now the U-shaped support arm 139 moves back to its starting position with movement 159 (FIG. 21 a).
  • the bobbin take-off carriage transports the full bobbins to a gate 132.
  • the bobbins are individually distributed to the push-on pins 133 of the gate by the push-out device 145 of the bobbin take-off carriage 131 (FIG. 21 c).
  • the movements 171, 172 and the pivoting movement 173 of the mandrel 145 bring it back into alignment with a further winding spindle which is at a standstill and has full bobbins 141.
  • the 22 shows a sleeve transport carriage which can be moved on wheels 180 along the machine front on the rails 121.
  • the bobbin transport carriage has a storage 181 for empty tubes 183.
  • the memory has an opening 184 in which two aligned empty sleeves 183 are exposed.
  • a clamping device 182 is provided which is suitable for moving into the opening 184 and for clamping one or more aligned sleeves between two gripping jaws.
  • an arm 186 pivotable about the pivot axis 187 is provided. The pivoting movement is effected by cylinder-piston unit 188. With 119 a winding spindle is shown, which belongs to a winding device located on a textile machine.
  • the arm 186 can be pivoted and positioned such that the empty sleeves 183 clamped in the clamping device 182 are aligned with the chuck 119. Furthermore, the swivel arm 186 can be moved along the axis 187 by means of a suitable drive device, not shown here, until the clamped empty sleeves 183 and the chuck 119 are spaced apart from one another at best. The sleeves can now be axially pushed out of the clamping device 182 and pushed onto the winding spindle 119 by means of the drive motor 185 and a suitable push-out device (e.g. rotating chain). Drive elements that are suitable for this purpose result e.g. from DE-OS 2 123 689 and DE-OS2 2128974.
