Definitions

  • the invention relates to a flat can for receiving sliver, which is delivered by cards or draw frames.
  • the flat can serves as a container for receiving the delivered sliver and its transport to a further processing machine of the spinning mill, through which the sliver is removed from the flat can again.
  • flat cans have the advantage that they can be set up and transported more cheaply.
  • the flat can can store more sliver than a corresponding round can.
  • filling and emptying the flat can is problematic compared to the round can, because the quality of the sliver must not be impaired in any way.
  • Known flat cans consist of 2 elongated, parallel side walls and 2 end walls. All walls are arranged perpendicular to the can bottom (EP 344 484).
  • the cross section of the flat can can be a rectangular shape, a rectangular shape with rounded corners (EP 344 484), a rectangular shape with rounded end pieces (DE-OS 40 15 938, Fig. 3A), or an oval shape.
  • the can plate which is known to be movable, also takes on the corresponding shape and is lowered or raised according to the filling status of the flat can. As EP 344484 shows, it was customary for flat cans that the can plate is positioned at the level of the can rim when empty. The positioning is achieved by springs.
  • the pantograph is intended to ensure that the can plate always remains horizontal during its lifting or lowering movement. At high traversing speeds, the can plate still tilts.
  • the flat can When filling with sliver, the flat can is usually moved back and forth under the filling device in the longitudinal direction of the can, so that the sliver is deposited cycloid-shaped on the can plate in the direction from one end wall of the flat can to the other end wall by this traversing movement.
  • several stored layers of sliver form a band column which, by means of its own weight, slowly lowers the can plate up to the stop on the bottom of the can.
  • the can plate has an edge that is angled downwards towards the base (can bottom) and lies with its angled surface except for a small gap on the can walls.
  • the can plate is carried at both ends by a spiral spring, which position the can plate in the unloaded state at the upper edge of the can.
  • the sliver column which consists of a large number of layers of sliver lying on top of each other, their mass increases. Especially when the flat can hits the reversal point of the traversing, the effect occurs that the Sliver column fluctuates due to its inertia in the direction of the respective end face. The entire sliver column fluctuates. This swaying is annoying because it affects the sliver storage that is still running.
  • pantographs which are symmetrically opposite each other on the longitudinal edges of the can plate, cannot prevent the can plate from tending to tilt in the direction of its longitudinal axis at increased traversing speeds. There is a risk of tilting against the wall. With the tilting of the can plate there is also the disadvantage that the single, suddenly loaded spiral spring bends out of its vertical axis.
  • the object of the invention is to achieve proper tape storage when filling an oscillating flat can, which also enables error-free tape removal, and at economical storage speeds, as are possible with round cans.
  • a feature of the invention is that the can plate has a bottom which is lowered in relation to the edge of the can in the empty position.
  • the depth of the depression in relation to the edge of the can corresponds approximately to a distance that two layers of sliver lie on top of each other. This advantageously ensures that sliver loops cannot be moved beyond the edge of the can at the beginning of the filling.
  • the angled edge of the can plate points in the direction of the upper edge of the can rim and lies against the can wall. This angled can edge extends approximately to the upper edge of the can. But it is also possible that the angled edge of the can plate is angled to the base of the pot and is also parallel to the can wall. In such a case, the can plate is held at a stop below the upper edge of the can when the flat can is empty. The stop is positioned on the can wall so that the can plate is held in the lowered position with respect to the edge of the can.
  • An advantageous further embodiment is that the two end sections of the can plate to the middle section as surfaces are inclined. The inclination of these surfaces can be changed and fixed. This embodiment ensures that the contact pressure of the sliver with respect to the turntable is reached earlier in the end sections than in the middle section. This also prevents the slings from moving.
  • Another feature is that the surface of the bottom of the can is structured so that the static friction to the sliver is increased.
  • the advantage is achieved that the first fiber sliver layers on the can plate do not shift during traversing and that the strips are deposited in the desired cycloidal shape over the entire length of the can plate.
  • the side walls of the flat can are corrugated near the top edge or over the entire surface. This corrugation of the side walls results in numerous resistance points, which lead to an additional and thus increased static friction between the fiber band column and the can wall. With this structurally simple measure, it is possible to dampen the fluctuation of the sliver column due to inertia. This also has the advantage of increased flexural rigidity of the side wall.
  • pantograph is arranged between the two spiral springs which are arranged in the region of the end walls.
  • This single pantograph is arranged in the middle of the jug bottom and at the crossing points this pantograph are arranged horizontally struts, which are rotatably mounted in the respective crossing point.
  • the ends of the struts are articulated to the opposite spiral spring. It is thus avoided in any position of the can plate and at high traversing speeds that the spiral spring bends out of its vertical position, as can be caused by fluctuations in the sliver column.
  • the sliver is delivered from the drafting device to the turntable 2.
  • the delivery direction A of the sliver is determined by the arrow.
  • the turntable 2 with its mouth of the tape guide channel 1 rotates stationary and is surrounded by a machine table 3.
  • the sliver leaves the mouth in the turntable 2 and is placed in the flat can 4 in a cycloid form.
  • the storage of the sliver is not shown.
  • Each individual layer of sliver is laid down over the entire width and length of the can plate.
  • the can plate is movably arranged on the can wall. With an increasing number of sliver layers, the can plate must be able to lower towards the can base.
  • the movement of the can plate can be carried out, for example, by an externally controlled lifting mechanism which is arranged under the can plate.
  • the lifting mechanism is in engagement with the can plate.
  • springs are arranged below the can plate, which move depending on the load on the can plate from an initial position (empty flat can) to a lowered position.
  • a filled flat can is transported to a spinning machine for further processing of the belt.
  • the width of a flat can therefore corresponds to the working width of a single spinning station.
  • the flat can 4 can have a rectangular or oval base. The rectangular base with rounded corners is preferred.
  • the flat can 4 is moved back and forth in the longitudinal direction (corresponding to double arrow B) underneath the turntable 2 of a draw frame or card, so that the can plate (not shown in FIG. 1) is covered with sliver over its entire length.
  • the roller conveyor 6 consists of a large number of freely movable rollers which are arranged next to one another and at least correspond to the traversing path.
  • the flat can 4 is oscillated on this roller conveyor 6.
  • the flat can in the upper third (below the lower can bead 5) is gripped on both sides by a traversing bracket 8 and 80, these traversing brackets being connected to a chassis 9.
  • This chassis 9 has a drive, not shown here. The drive is controlled according to a program for filling the flat can 4.
  • the chassis 9 is guided along the rail 10.
  • FIG. 2 documents the can structure known up to now according to EP 344 484, as can be seen within the can wall 13 and below the can plate 14.
  • the flat jug is moved back and forth, ie it changes.
  • the traversing speed is decelerated to the value zero at the reversal point, in order then to accelerate to the traversing speed immediately after passing through the reversing point.
  • the analogous braking and acceleration process takes place.
  • known flat cans after the formation of the first sliver layers for the end-side sling are displaced beyond the edge of the can (see FIG. 2).
  • the can plate 14 in known cans is arranged in one plane with the edge of the can or a little higher, a shifting of the end sling is favored.
  • the pressure of the sliver on the turntable intended by the raised can plate is not sufficient to hold the slings in the area of the end wall of the flat can.
  • This design of the can plate and its arrangement avoids the formation of uniform sliver layers and later hinders the pulling of the sliver from the flat can. There is a risk of the tape breaking.
  • the can plate In order to prevent the first sliver layers from shifting when the flat can is traversed, the can plate is lowered over its entire length relative to the edge of the can (upper can bead 5).
  • Figure 3a shows this fact.
  • the depth of the lowering of the can plate 140 relative to the edge of the can corresponds approximately to a distance that two layers of sliver lie on top of each other.
  • FIG. 5 shows the lowering of a can plate 142, the lowering being forced by the stop 51.
  • the stop 51 is arranged on the inner wall below the upper can bead 5. When the can plate 142 is lifted, it is always arranged below the upper can bead 5 by the stop 51.
  • the stop 51 is not an additional component but can expediently be taken into account when shaping the can wall.
  • an embodiment of the can plate is also feasible in which the two end sections of the can plate are angled in accordance with an inclined plane (FIG. 3b). Slightly spherically curved surfaces can also be used.
  • the length L of each of the two inclined planes corresponds to a deposit radius of the cycloidally laid fiber sliver.
  • the height H of this inclined plane corresponds to a sufficiently small free space between the top of the can and the flat part of the can plate 141, as is present at the start of filling.
  • the inclined planes in the End sections of the can plate have the effect that the first sliver layer and the immediately following layers in this area are pressed onto the machine table 3 earlier and stronger than the remaining rest of the layers in the middle section. The increased pressure of the sliver layers between the can plate 141 and the machine table 3 in the end sections of the can plate prevents the sliver layers from shifting.
  • the can plate has a structured surface 17 (FIG. 3d).
  • a nubbed surface it is also conceivable to have a nubbed surface.
  • Figure 3 c shows a flat can according to the invention in the inner structure.
  • the can plate 140 is carried by a single pantograph 120, which is arranged centrally below the can bottom 140.
  • struts 16, 160 are arranged in a horizontal position, which are rotatably mounted in the respective intersection.
  • the ends of the struts are articulated to the respective opposite ring spring 110, 111.
  • the articulated connection is achieved by the ends of the struts (16, 160) being formed into eyelets (16.1, 16.2; 160.1, 160.2). It is thus avoided in every position of the can plate and at high traversing speeds that the spiral spring bends out of its vertical position, as was previously caused by fluctuations in the fiber band column.
  • the can plate With increasing sliver storage, the can plate is pressed down due to the sliver weight. From the large number of sliver layers, a sliver column is formed, which as a result their inertia tends to fluctuate in the reversal points of the oscillation. The swaying develops forces that act on the can wall and the traversing bracket. In order to dampen this swaying of the sliver during the traversing of the flat can, the side walls near the upper edge (upper can bead 5) are corrugated. However, the entire side surface can also be corrugated.
  • the corrugation 18 is such that, starting in the vicinity of the upper can bead 5, the can 4, wave crests and troughs follow the perpendicular to the can base, ie point in the direction of the lower edge (FIG. 4).
  • wave crests and troughs run parallel to the upper and lower edge of the side wall.
  • the corrugation 18 creates numerous resistance points, which lead to an increased frictional connection between the sliver column and the can wall. The advantage is that fluctuation in the sliver column is reduced.
  • the flat can 4 has an upper can bulge 5 and a lower can bulge 50.
  • Upper and lower can bulges 5, 50 are known to project laterally at the same distance laterally beyond the can wall. This known condition is documented in FIG. 6.
  • a flat can 4 and 40 are located under a spinning station S1 and S2. Each flat can has approximately the width of a spinning station, with a small lateral distance a remaining between the adjacent flat cans 4, 40. Since this side spacing a is small, and to make changing the can easier, guide rails are arranged on the base of the spinning machine, guide rails LS1, LS2 and LS3 are shown in part. These guide rails shorten the lateral distance a in the area of the lower can bead 50.
  • FIG. 7 shows the design of the flat can according to the invention in the region of the lower can bead 50.
