Definitions

  • the invention relates to the depositing of fiber material in a spinning can.
  • a method for depositing fiber material, in particular fiber sliver includes rotating a stationary depositing plate over a can. In the case of a round jug, it rotates, and in the case of a rectangular jug, it is oscillated. This leads to the fact that after each Kannenum rotation or traversing movement, the next layer of sliver is deposited over the same sliver rings of the previous sliver layer. As a result, the points of intersection of the individual sliver storage levels lie vertically one above the other. This causes the sliver to gain height very quickly. This requires that the fiber tape, in order to be able to deposit enough fiber material, must be pressed strongly, which has a negative effect on the fiber material quality.
  • a method for depositing fiber material in a can has a first step in which a fiber material depositing head is positioned above the can in a predetermined starting position. This is followed by a cycle.
  • the cycle comprises a first cycle step in which a predetermined length of fiber material is deposited in the can. I.e. the position of the storage head does not change.
  • the storage head is shifted away from the current position according to predetermined information. This means that it can be precisely determined how much fiber material is deposited in the can by the depositing head while maintaining a position.
  • the predetermined shifting of the depositing head makes it possible to reduce the number of superimposed layers at the intersection points with a given number of layers and thus maximize the filling quantity and / or in particular be able to positively influence the quality of the deposited fiber material.
  • the predetermined fiber material length differs from one another between at least two cycles. In particular in the case of round cans, this makes it possible to predictably vary the position of the crossing points even with only two predetermined positions of the storage head.
  • the cycle is preferably repeated until the jug is filled.
  • the dispensing amount is a predetermined length of fiber material during one can revolution. This is a form that is very easy to implement in terms of control technology to optimize the storage of fiber material.
  • a predetermined fiber material length corresponds to the amount dispensed during the laying down of a fiber material ring. This enables the placement head position to be changed several times during the placement of a fiber material level that is placed during one can rotation. The storage head can be shifted gradually or even continuously from one end position to the other.
  • the disposition of the storage head is preferably carried out in at least one cycle between several predetermined end positions of the storage head. This increases the degree of freedom to be able to optimally lay down the fiber material.
  • the sliver deposit is preferably carried out in such a way that an integral number of fiber material rings is prevented from being deposited during one can revolution. This means that after one can rotation, a sliver ring does not start but a little later. This also has the effect of reducing the positions that lie one above the other at the crossing points.
  • the displacing of the storage head is preferably carried out in that the storage head is specifically accelerated at the beginning of the respective displacement and / o which is specifically braked at the end of the respective displacement. This leads to relatively low loads on the can depositing device, which has the depositing head and moves.
  • the deposited fiber material is preferably a fiber tape.
  • FIG. 1 shows a round can in two filling states according to a fiber material storage method according to a first embodiment of the invention
  • Figure 2 shows two images of sliver storage in a round can, ge according to a second embodiment of the invention
  • FIG. 3 shows a round can which has been filled according to a fiber material depositing process according to a third embodiment of the invention
  • FIG. 4 shows a larger round can which was filled according to a fiber material depositing method according to the third embodiment of the invention
  • FIG. 5 shows a round can in two filling states, which was filled according to a fiber material storage method according to the fourth embodiment of the invention
  • FIG. 6 is a diagram showing storage methods according to other embodiments of the invention
  • FIG. 7 shows a round can in two filling states according to a fiber material deposition method according to the embodiment of the invention shown in FIG. 6d and in a side view.
  • Figure 1 shows a round can 1 in two filling states according to a fiber material storage method according to a first embodiment of the invention.
  • the can 1 is shown in a state in which it has passed through a single rotation during the filling with fiber material.
  • reference numeral 7 In the case of the sliver rings deposited in this case, only the uppermost one is provided with reference numeral 7 in the figures.
  • a bunghole 5 is formed in the middle of the can 1.
  • the position of the depositing head changes from a position 3 to a position 2.
  • the position 2, 3 always denotes the center point of the respective deposited fiber strip 7.
  • the state shown in FIG. 1b is shown. As can be seen, the bung hole 5 has become very small. This also reduces the number of layers of fiber material at the intersection points in the vertical direction, i. H. according to FIG. 1 into or out of the plane of the sheet.
  • Figure 2 shows two images of sliver storage in a round can 1, according to a second embodiment of the invention.
  • the storage head According to the method shown in Figure 2a, there are three positions 3-5 for the storage head.
  • the image shown in FIG. 2b with different storage levels 6 1 - 6 5 results as a variant.
  • the bunghole 5 is also very small.
  • the rings 7 are preferably placed along the interior of the jug 1, which is otherwise not shown.
  • the storage head then changes to position 3, which corresponds to a middle position of the storage head. After that it is in two levels one above the other, the storage head moved to position 2 or left there. Then it goes back to position 4, and then to position 2.
  • the change between positions 2 - 4 therefore always takes place after a single can revolution or the sliver length, which is deposited in the respective position 2 - 4 during one can revolution .
  • the data regarding the respective sliver length can be stored in a database in connection with the respective storage head position and can be easily read out by means of the control of the storage head. The result is a very easy to implement method of moving the storage head or leaving it in the respective position.
  • FIG. 3 shows a round can 1 which has been filled using a fiber material depositing method according to a third embodiment of the invention. There are also three deposit positions 2 - 4. However, the sliver is deposited in such a way that the positions are continuously approached one after the other (sequence: 2, 3, 4, 2, 3, 4, ).
  • FIG. 4 shows a round can 1 which has been filled using a fiber material deposition method according to the third embodiment of the invention.
  • the diameter of the round can 1 shown here is larger than in FIG. 2. This results in the deposition image in FIG. 4 which is somewhat different from that in FIG.
  • FIG. 5 shows a round can 1 in two filling states according to a fiber material deposition method according to a fourth embodiment of the invention.
  • this embodiment there are again only two positions 2, 3 for the storage head.
  • the delivery head is continuously moved from position 2 to position 3 and back again during one can rotation.
  • the distance between the sliver rings 7 and the inner wall of the can 1 preferably changes continuously.
  • FIG. 5a after one can rotation, the sliver ring 7 rests against the inner wall of the can 1, offset somewhat to the right with respect to a vertical central axis.
  • the center of the corresponding sliver ring 7 was, however, directly on the central axis. I.e. Position 2, which the delivery head repeatedly moves to, “wanders” along a circular line around the center of the jug 1.
  • FIG. 6 shows three diagrams which represent different storage methods.
  • the position of the depositing head is changed here between two positions 2, 3 only during the first three can revolutions.
  • the storage head then remains in position 3, as is known from classic storage methods.
  • the dashed lines are used to clarify the corresponding breakpoints of the graph in relation to the respective cannon revolution.
  • the change between positions 2, 3 takes place after a little more than one can rotation (for example after a can rotation by 370 °), and again until the can 1 is filled at can rotation n.
  • the change between positions 2, 3 takes place alternately after a little less than one can rotation (for example after a can rotation by 350 °) and after exactly one can rotation, again until the can 1 at can rotation n is filled.
  • FIG. 7 shows a round can 1 in three filling states according to the fiber material deposition method of FIG. 6d.
  • the can 1 is shown in a state in which it has passed through a single revolution during filling with fiber material
  • FIG. 7b shows the can 1 after two can revolutions.
  • FIG. 7c shows the effect of changing the position of the depositing head when the jug 1 is filled. This change leads to the fact that the corresponding points of two sliver rings 7 lying directly one above the other, which are otherwise vertically one above the other, “migrate”, specifically to the top right at an angle. It is clear that consequently fewer layers are vertically one above the other at the crossing points when the can 1 is full.
  • the invention is not limited to the above-mentionedistsfor men. They can be exchanged for one another in any form or combined with one another.
  • the number of positions that the delivery head moves to can vary. In particular, it can be greater than 3.
  • the method is not restricted to a specific fiber material.
  • the fiber material is preferably sliver, can also be, for example, before yarn.
  • the method according to FIG. 5 can be combined with the method according to FIG. 1, for example, in such a way that the ring position 7 according to FIG. 5a changes after one can rotation, but the placement head also changes its position.
  • the angle of rotation of the can 1 with regard to the change in position of the storage head can always or only partially be the same, smaller or greater than 360 ° in all methods.
  • the invention creates a very universally applicable method, in which it can be determined in advance where intersection points are to be found, and how many are likely to lie on top of each other at these intersection points.
