Definitions

  • the invention relates to a sliver can for storing sliver in an orderly manner, with a can body open at the top, a spring plate which can move vertically within the can body under the weight of the sliver and which is acted upon from below with the pressure force of at least one spring, and with retaining means for the spring plate.
  • Spinning cans are used to take up spinning material, which consists of a fleece-like band of stretched and parallelized fibers.
  • the sliver is filled into the sliver can by circularly moving the sliver emerging from the outlet of a can stick and thereby filling it into the can body driven about its axis. This creates loops that are placed one above the other on the spring plate of the spinning can, which is loaded by a compression spring. Under the action of the weight of the spun material deposited in this way, the spring plate gradually moves downward against the force of the spring, the level of the spinning material within the can body being retained regardless of the filling quantity by selecting a spring with a suitable spring identification.
  • the can is filled when the spring plate strikes the bottom of the can body, the spring being compressed to its smallest dimension.
  • the pressure force of the spring must be slightly less than the weight force of the sliver sliver. If, on the other hand, the force of the spring is too great, this leads to an undesired pushing out of parts of the sliver material from the open-top spinning can after the pressure of the can stick has been removed.
  • EP 0 255 880 A1 It has therefore already been proposed in EP 0 255 880 A1 to attach a rigid latching device to the underside of the spring plate, which, in the lowest position of the spring plate, locks the spring plate to the bottom of the spinning can. In this way, the spring plate is held in the lowest position during transport of the filled spinning can and when it is inserted into a subsequent machine, and the sliver that is laid down cannot be pushed up out of the can body even when a strong spring is used.
  • a disadvantage of the spinning can according to EP 0 255 880 A1 is that the retaining means described therein only take effect in the form of the lock and only after the spring plate has reached its lowest position within the can body.
  • a spinning can with the features mentioned above is known from DE-OS 27 12 982.
  • this publication proposes loading the underside of the spring plate in addition to the normal spiral spring by an additional spring which is supported on a plate with its lower end facing away from the spring plate. which is adjustable in height in the can body.
  • the plate is provided with clamping elements that can lock the plate at any height within the can body.
  • the spring plate is subject to the summed spring forces of the two springs at any height.
  • the additional spring migrates in the sense that its lower end has a different height within the can depending on the clamped state. Nevertheless the spring plate is always subject to the force of this additional spring acting from below. If the pressure acting on the deposited sliver from above is relieved in this spinning can, some layers of the sliver can still undesirably swell out of the can.
  • the invention is therefore based on the object at a spinning pot for orderly depositing sliver with simple means to achieve an increase in the Kannenhellgrades, without being able to come to an undesirable pushing out the already deposited sliver.
  • the retaining means prevent a return movement of the spring plate caused by spring force, that the retaining means are effective over the entire distance that the spring plate can travel within the can body, and that the retaining means on the spring plate and preferably the underside of which is attached and provided with at least one locking device which blocks the spring plate against the pressure force of the spring.
  • retaining means are provided which are effective over the entire path of the spring plate and are provided with at least one locking device which blocks the spring plate against the pressure force of the spring. This creates the possibility of using a stronger spring with a larger depositing pressure when filling the sliver can, which results in an improved can filling degree with denser packing of the sliver. This advantage arises regardless of the total filling quantity, since the retention means are effective both when the spinning can is fully filled and when it is only partially filled.
  • the retention means work independently of the speed at which the sliver is laid down and also independently of the material properties of the sliver. For the function of the retention means, it is therefore irrelevant whether the filling of the spinning can, for. B. takes place by means of a jug at high or low speed. Just as little it matters what thickness and compressibility the sliver has.
  • the restraint means preferably consist of a flexible and non-stretchable tension element between the spring plate and the bottom of the can body.
  • the tension element is a roller spring.
  • Such coiled springs have the property of winding themselves up as a result of a pre-embossed bending tension.
  • the advantage of the roller spring is that it can be arranged with its rolled-up end in the area of the bottom of the can body, where it requires relatively little space, so that the vertical movement path of the spring plate within the can body is not restricted. According to one embodiment, it is therefore provided that the rolled-up spring is mounted with its rolled-up end in the region of the end plate inside or outside the can, and that the free, stretched end of the rolled spring is attached to the underside of the spring plate.
  • the retaining means are composed of a flexible and non-stretchable tension element between the spring plate and the end base of the can body and a winding roller for the tension element which can be blocked by the arrester.
  • the winding roll can also be arranged in the area below or above the end bottom of the can body, where it requires relatively little space.
  • the invention proposes a release element for the arrester, the release element preferably protruding from the underside of the can body.
  • the spinning can shown in FIG. 1 is composed of a can body 2 provided at the bottom with a bottom 1 and open at the top, a spring plate 3 arranged in the can body 2 and a spring 4 which, resting on the bottom 1, oppose one another from below supports the spring plate 3.
  • a spring plate 3 arranged in the can body 2 and a spring 4 which, resting on the bottom 1, oppose one another from below supports the spring plate 3.
  • several springs can also be present, care being taken that the spring plate 3 is supported essentially horizontally.
  • the spring plate 3 is guided along the inner wall 5 of the can body 2 with little play.
  • the can body 2 is cylindrical designed so that the spring plate 3 has the shape of a round plate. Rollers 6 on the underside of the spinning can facilitate their transport.
  • the spinning can is used to hold sliver deposited in loops. 2 shows the spinning can in the state completely filled with sliver 7.
  • the spring plate 3 has lowered into its lowest position near the bottom plate 1. The spring 4 is compressed to the maximum.
  • Fig. 2 shows a basic problem with spinning cans:
  • the characteristic of the spring 4 must be matched exactly to the sliver to be stored in conventionally constructed spinning cans. Regardless of the height of the spring plate 3, the pressure force exerted by the spring must always be so great that the fiber band column resting on the spring plate does not protrude, or, as shown in FIG. 2, only by a certain height above the upper edge 8 of the can body 2 . If the pressure force of the spring is too low, the entire fiber sliver column disappears within the can body, so that new fiber sliver cannot be deposited with the pressure required for this.
  • the retaining means 9 in a first embodiment shown in FIGS. 3 and 4 consist of a tension element 10 in the form of a flexible rope, the length of which is not required is taken up by a spring-loaded winding roller which is mounted in the area of the end floor 1.
  • the free end of the taut tension element 10 is, as shown in FIG. 1, attached to the underside of the spring plate 3 in the middle.
  • the winding roll 11 is designed as an elongated drum, on the circumference of which a helical groove 12 is incorporated for receiving the cable turns.
  • the winding roll 11 is mounted on both sides in a housing 13 which is attached to the bottom 1 of the spinning can.
  • the winding roller 11 is provided with a spring 14 preloaded in the sense of a winding of the tension element 10.
  • the spring 14 is arranged as a helical spring in a central cavity 15 of the winding roll 11.
  • the arrester 15 is a friction wedge, which releases the winding roll 11 in one direction and blocks movement in the other direction by clamping.
  • the detent 15 can be released by means of a release element 16 which protrudes from the underside of the can body 2.
  • the winding roll 11 is mounted horizontally.
  • the tension element 10 is deflected once by 90 ° and is also wound up in multiple layers on the winding roll.
  • the spring plate 3 decreases increasingly under the influence of the weight of the sliver and the contact pressure of the can stick.
  • the restoring force of the spring 14 of the winding roll 11 ensures that the tension element 10 always remains under tension.
  • the retaining means 9 become effective.
  • the compressive force of the spring 4 exceeds the weight of the sliver lying thereon, the spring plate 3 is blocked against an upward movement, so that the sliver cannot be pushed up out of the spinning can. Only when the lock 15 is released by means of the release element 16 is the winding roller released, so that the spring plate 3 then moves upwards under the action of the spring 4. This release usually takes place then after the spinning can has been completely emptied.
  • roller spring 18 is used as the retaining means 9 or tension element 10, the wound end 19 of which is located in a cylindrical chamber 20.
  • the roller spring 18 is a narrow sheet metal strip which, because of the material structure, tends to wind itself up automatically.
  • the free end of the roller spring 18 is attached to the underside of the spring plate 3 analogously to the first embodiment. Since a roller spring 18 tends to roll up automatically due to its inherent tension, an additional spring corresponding to the spring 14 is not required in the embodiment variant according to FIGS. 3 and 4.
  • An approximately quarter-circle lever is used as the lock 15, one end of which is mounted on an axis 21 which is fixed to the housing and extends parallel to the winding axis.
  • the roller spring 18 wraps around the quarter-circular outer contour of the arrester 15, the free, elongated end of the roller spring 18 leaving the arrester 15 at the end which faces away from the end with the axis 21.
  • the quarter-circle lock 15 is provided with a relatively short extension 22, so that the lock 15 can be regarded as a lever, the long lever arm of which is formed by the quarter circle, and the short lever arm of which consists of the extension 22 .
  • This extension 22 forms on her outer edge a clamping cam 23a, which presses the roller spring 18 against a friction-increasing surface 23b under the action of the quarter-circular lever.
  • the gap between the extension 22 with the clamping cam 23a and the opposite friction-increasing surface 23b is so small that the roller spring 18 fits straight through.
  • the pivotable arrester 15 endeavors to press the clamping cam 23a against the friction-increasing surface 23b, and in this way to clamp the roller spring 18. If, on the other hand, the tensile force in the free end of the roller spring 18 is relieved, the arrester 15 swivels away from the wound end 19 of the roller spring 18, as a result of which the gap between the clamping cams 23a and the friction-increasing surface 23b opens, and the roller spring 18 continues to roll up while material is being drawn in, until the free end is tightened again.
  • a release element 16 is also provided in the embodiment according to FIG. 5, which is actuated via a cam 17. When released, the release element 16 pivots the locking device 15 away from the wound end 19 of the roller spring, so that the clamping is released and the roller spring 18 unwinds under the influence of the large spring 4.
  • cams 17 can be fastened in the bottom, which exert pressure on the release element 16 when the spinning can moves over, and thus unlock the arrester 15.
  • the characteristic curve of the spring 4 is preferably designed such that its compressive force exceeds the weight of the sliver resting on the spring plate 3 by at least 10%. This makes it possible to deposit new sliver in the spinning can with a relatively high back pressure, and thus to improve the degree of filling.
