Definitions

  • the invention relates to the storage of the sliver end after filling a flat jug.
  • the filling station for the flat can is a textile machine for spinning preparation such as a card or stretch. These machines have one stationary rotary table with belt guide channel. While the rotation of the turntable is through this tape guide channel Sliver laid cycloidal in a flat can. Is the Flat can filled, the sliver is separated and one end of the sliver stored on the flat can. The level of automation required the belt feed on further processing machines of the spinning mill becomes essential through the storage of the sliver end on the flat can influenced.
  • FIG. 5 shows that a flat can after filling from The turntable is pushed into a position at the separator.
  • the end of the belt on the filled jug lies after cutting a random position of the end wall. It turned out to be Difficulty that additional processing increases is to drive around the end of the sliver at the can edge or at the To look for and grasp the end wall of a flat can.
  • a solution for flat cans is shown in DE-OS 41 07 309. On a holder is arranged on the end wall of the flat can, the can hold a gripper. The gripper positions the end of the belt on the flat can. This solution has the disadvantage that at everyone Flat can an additional holding device for the sliver end must be installable.
  • the sliver end has a relatively large length tolerance. This length tolerance results, for example, from the tape separation process.
  • the different length of the sliver end is usually through measures in the subsequent tape end treatment Can transport vehicles or in front of the spinning machine to the desired one Brought to length then automated the spinning machines to be able to be fed.
  • the object of the invention is in the area of the filling station place the end of the belt on a filled flat jug in a defined manner and prepare to be automatic with minimal effort Handling the flat can during transport and the end of the belt to facilitate the spinning machine.
  • the flat can is oscillated under the turntable, so that Sliver is laid cycloidal.
  • the cycloid shelf takes place from one end wall of the flat can to the other.
  • a such storage path forms a sliver layer.
  • a filled jug has added a variety of such layers of sliver.
  • the traversing speed of the flat can is based on the delivery speed of the turntable.
  • the start, the operation and the turntable and flat can are braked synchronous.
  • the method according to the invention assumes that the positions between the mouth of the turntable, the separator and the flat can are mutually changeable and adjustable and that this setting has an influence on the storage location of the strip end and the length of the strip end.
  • the flat can and the mouth of the turntable have reached an adjustable standstill position.
  • the turntable mouth is always in a defined position so that the sliver loops are pulled off when the flat can is moved in such a way that the sliver comes to rest in the central region of the end face at the end of the displacement path of the flat can. While the flat can is being moved, sliver loops are pulled from the last sliver layer.
  • the sliver is drawn off over the upper edge of the can at the front. Since the loops are laid out in a circle, the sliver to be drawn off carries out a traversing movement on the upper edge of the can of the end wall. This traversing of the sliver takes place during the period of shifting.
  • the sliver also runs through the central region of the upper edge of the can of the end wall. A separation position of the flat can is reached when the flat can has passed the functional area of the belt separator and the sliver that has been pulled off is arranged in the middle area of the upper edge of the can of the end wall. The sliver is then separated in this position, the separation position.
  • the method has the advantage that additional, constructive expenses are extremely low and are only used to determine positions.
  • the process can be retrofitted to existing textile machines.
  • An advantageous embodiment is based on determining the position of the mouth of the turntable and, when the separator is in a fixed position, determining the next possible displacement path of the flat can, where the sliver lies in the central region of the upper edge of the can of the end wall.
  • This version is advantageous because it requires a small machine footprint, since the flat can requires a minimum of a displacement.
  • the fiber sliver can be deposited so that the fiber sliver hangs down over the loops of the fiber sliver on the end wall. Due to the storage over the loops, fiber sliver is fixed in its position due to static friction, which is convenient for can transport.
  • Another advantageous embodiment of the invention is that for Separate the sliver from the flat can in the standstill position is held and in this position the flat can separation of the sliver between the pair of calenders and the belt guide channel of the turntable. The flat can is then in the takeover position moved, the separated sliver end is removed from the Belt guide channel pulled and positioned itself in constant length at a defined position on the edge of the can the end wall.
  • the end of the sliver does not have to differ from that in the flat can discarded slings are unwound, so that there is no influence on the quality of the deposited tape.
  • the positioning is done with little effort and without a holding device reached.
  • Another advantage is that the length the end of the belt can be influenced by the standstill position something can be varied.
  • this embodiment of the invention is thereby performed that a traversing device for the flat can and a separator are arranged. Both are with a machine control connected to the route.
  • the mechanical separator has several tools.
  • the device has the advantage that it can be realized with little effort.
  • Figure 2 shows a schematic side view of such a flat can for filling on a route.
  • a partial assembly of the line is the pair of calender rolls 16 and the turntable 12 in the machine table 17. That is the filling station BS.
  • the area of the filling station BS includes the traverse path of the flat can, the standstill position D of the flat can, the isolator 18 and the separating position E of the flat can.
  • the rotary table 12, which is rotatably mounted about the axis of rotation 13, is arranged stationary in the machine table 17.
  • the turntable 12 includes a belt guide channel 14. In addition to the opening, which is arranged below the pair of calender rollers 16, the belt guide channel 14 has an opening 15 which faces the flat can 1.
  • FIG. 3 shows the turntable 12 with its mouth 15 and, from this viewing direction, the can 1 underneath, the can plate 8 and the upper can edge 6 surrounding it being recognizable. From this viewing direction it can be seen that the can can be moved between the traversing positions A and B. It is thereby achieved that the turntable 12 deposits 8 sliver in cycloidal form over the entire length of the can plate.
  • a known measuring device for measuring the tape length on the Line gives a signal that the flat can has the desired level has reached. With this signaling, the route still has Delivery speed. In preparation for stopping and The later band separation will slow the line down switched.
  • the controller 40 according to FIG. 5 recognizes this switching to slower speed. To this end the controller 40 calculates from the rotational speed of the turntable, at delivery speed, the turnaround time of the turntable. This calculation can be carried out continuously, for example the older value is compared with the current value and one Characteristic is formed, so that the controller 40 from the characteristic deviation a switch to a lower speed recognizes.
  • the position sensor 32 near the periphery of the turntable 12 provides the corresponding signals to the controller 40 allow a calculation.
  • the turntable 12 is switched to slower speed. This also affects the speed of the flat can.
  • the Position sensors 30, 31 transmit the current position of the Flat can on the traversing path.
  • the controller 40 calculates how much Revolutions of the turntable 12 from the start of a braking process would complete until it stopped in position P. The time required for this is called the run-on time. It is note that the number of revolutions of the turntable per Time unit depends on the set speed with the the turntable 12 rotates. Depending on this speed of rotation the turntable 12 also has a different run-on time. It therefore becomes different speeds of rotation of the turntable the associated run-on time through the Control 40 determined.
  • the mouth 15 of the Turntables have reached their defined position P at a standstill.
  • the flat can has also reached a position advantageously the traversing position A. That is why advantageous because when you later move the flat can to right in Fig. 3 in the direction of separator 18, the sliver immediately the can edge 6 is pulled off and not over the stored position of the sliver comes off.
  • the position sensor 32 (FIG. 5) is, for example, in the vicinity of the Scope of the turntable 12 installed, where, for example the mouth 15 must be positioned at a standstill. To this The purpose is near the mouth 15 of the contactor 150 for the position sensor 32 arranged. This arrangement is shown in Figure 6. The controller 40 must now the time at the beginning of Know braking so that the mouth 15 exactly opposite the position sensor 32 comes to a standstill.
  • FIG. 4b shows the standstill position assumed D the flat can.
  • This standstill position D was during traversing identical to traversing position A.
  • Die Standstill position D can deviate somewhat from the traversing position A.
  • the standstill position D is characterized by that turntable 12 and flat jug 1 stand still, the mouth 15 of the turntable 12 has assumed a defined position P.
  • the position P of the mouth 15 of the turntable 12 and thus the standstill position D of the flat can slightly are influenced by machine-internal influences, so that there are deviations can give the saved value of the run-on time.
  • Such an influence within the machine exists, for example, in the start-up phase of the machine until this operating temperature is reached Has.
  • the flat can is made out the standstill position D moved to a separation position E.
  • This shift can be done by the traversing device or a additional transport shuttle for the can changing device.
  • the flat can covers the displacement path V. Since that Sliver is stored in loops when moving the Flat can these loops of the last sliver layer partially deducted again. It is pulled off via the upper edge of the can 6 of the end wall, the sliver at the edge of the end wall shifts. The middle area of the can rim is also repeated 6 of the end wall 2, 3 reached.
  • the separation position E is reached when the flat can reaches the functional area of the belt separator 18 has passed and the sliver in the middle Area of the upper can edge 6 of an end wall lies. Of the Separator 18 was in such a position opposite the separation position E the flat can installed that the sliver after clamping and separation by the separator 18 receives a defined length and comes to rest in the middle area of the upper edge 6 of the can.
  • the middle area of the upper edge 6 of the can comprises an area for example a sliver thickness on either side of the longitudinal axis of the can, the width of the middle range is variable is by the length of the displacement path V.
  • This defined shelf the sliver end provides with the least design effort the advantage that the sliver end after transporting the flat can automated from the separation position E to the spinning machine found and ready for further processing. It does not apply thus devices on a can transport system or on the Spinning machine that uses the sliver for automated further processing have to prepare or prepare. In the inventive The usual holding devices are also no longer required on flat cans.
  • FIG. 5 shows an embodiment of the invention according to the device shown.
  • the flat can 1 is located on a traversing device 20.
  • This known traversing device 20 takes over the traversing between traversing position A and the traversing position B (Fig. 2).
  • the traversing device 20 the flat can 1 is also brought into the standstill position D.
  • Example Fig. 4-4c is the traversing position A, for example identical to the standstill position D.
  • the standstill position D is controlled by the position sensor 30.
  • Using a traverse device 20 can the flat can 1 also in the separation position E to be moved.
  • the separation position E is due to the position sensor 31 determined.
  • the number of revolutions of the turntable is determined by the position sensor 32 determined. Transmit the position sensors 30, 31, 32 their signals via electrical connections to a controller 40.
  • the position sensors can work touching or non-contact. This depends on the physical detection principle used.
  • a proximity sensor is usually used, the is activated via a metallic switch flag and on the turntable 12 or attached to the flat can 1 or the traversing device can be.
  • Figure 7 shows schematically a route 100 of the textile industry and a flat can 140 and its traversing device 160 and the buffer 151 of a transport system for flat cans.
