Definitions

  • the invention relates to a device for homogenizing the sliver or nonwoven in a card, card or the like.
  • a device for homogenizing the sliver or nonwoven in a card, card or the like With a licker, a feed roller and a dining table, wherein a sensing element is provided for the amount of fiber drawn in, which is controlled by a control device with the drive motor for the Feed roller is connected.
  • a stationary bearing below the stationary feed roller, on which a plurality of feeler levers are movably mounted as a sensing element (dining table).
  • the end of the feeler lever is directly adjacent to the licker-in and is spring-loaded.
  • the other end of the feeler lever is connected to a measuring device (so-called piano lever) which detects or summarizes the displacement of the feeler lever as a function of the thickness of the fiber material drawn in. It is disadvantageous that when the fiber material is taken over from the feed roller, the workers of the licker-in (tearing forces) act on each feeler lever and can thereby falsify the measurement result.
  • the dining table consists of a plurality of spring-loaded feeler levers which are connected to a so-called piano lever mechanism, which overall is very complex in terms of construction.
  • the invention is therefore based on the object of providing a device of the type described at the outset which avoids the disadvantages mentioned, which in particular in a structurally simple manner avoids harmful forces on the sensing element and specifies a specific measuring location.
  • the dining table has at least one opening, the sensing element reaching through the opening.
  • the fact that the dining table is present between the movable sensing element and the licker-in creates a distance between the measuring point and the licker-in. In this way, the licker is able to act on the fiber material lying on the dining table, but there is no harmful effect on the fiber material lying on the sensing element, especially not at the measuring point.
  • Another advantage is that the measuring point in the clamping zone between the sensing element and the feed roller extends over a very short area or only over a line parallel to the axis of the feed roller or a point. In contrast to the known device, a specific measuring location is thereby clearly defined.
  • the opening is a recess which can be closed on all sides or open on one side (i.e. on a short outer edge).
  • the cutout is preferably rectangular, the long edges of the cutout running in the width direction of the dining table in relation to the working direction of the device.
  • the sensing element is expediently rectangular, the long edges of which run in the width direction and the short edges of which run in the working direction.
  • the outer end of the sensing element preferably extends approximately up to the center line of the feed roller in the direction of the licker-in.
  • the sensing element is preferably mounted on a fixed pivot bearing. Appropriately, the pivot bearing acts with a force element, for. B. counterweight, spring or the like together.
  • the sensing element is preferably movably mounted in the vertical direction.
  • the sensing element is preferably resiliently mounted at its two outer ends.
  • the sensing element is expediently mounted on a holding member.
  • the sensing element is preferably mounted rotatably about a horizontal axis.
  • the guide element or the holding member preferably has at least one plunger core with plunger coil.
  • the sensing element is expediently an analogue contactless distance sensor.
  • Fig. 1 shows a card, e.g. B. Trützschler-EXACTACARD DK 715, with feed roller 1, dining table 2, licker-in 3, drum 4, customer 5, doctor roller 6, squeeze rollers 7, 8, fleece guide element 9, pile funnel 10, take-off rollers 11, 12 and traveling cover 13.
  • the feed roller 1 is stationary.
  • the dining table 2 is in one piece; the rear area 2a and the front area 2b are shown.
  • the dining table 2 has a continuous recess 19 between the areas 2a and 2b.
  • the end of region 2b facing region 2a extends (as seen from licker-in 3) to just past the vertical center line 1a through feed roller 1.
  • the other end of region 2b extends into the gap between feed roller 1 and licker-in 3.
  • the sensing element 20 is force-loaded by a pressure spring 14 which on the one hand against the underside of the feeler lever 20 and on the other hand against a stationary abutment presses.
  • the sensing element 20 is designed for displacement with respect to the feed roller 1 as a function of the amount of fibers 15 drawn in.
  • the sensing element 20 is assigned a measuring element 16 for the displacement, which is connected via a control device 17 to the drive motor 18 for the feed roller 1. If a change in thickness of the amount of fiber supplied, for. B. is a thinner or thicker point, so the sensing element 20 evades accordingly. This deviation is detected by the measuring element 16 and fed to the control device 17, which sets the drive motor 18 for the feed roller 1 correspondingly faster or slower.
  • the area 2a of the dining table 2 is provided in the fiber material feeding device, via which the fiber flakes are fed in the direction of the feed roller 1.
  • dining table 2 is formed in one piece.
  • the dining table 2 has two openings which are designed as continuous recesses 19a, 19b (see FIG. 2c) in a rectangular shape.
  • the long edges u ', u''andv', v '' of the recesses 19a and 19b run in the width direction of the dining table 2.
  • the short edges x ', x''andy', y '' of the recesses 19a and 19b run in the working direction.
  • a sensing element 20a or 20b is arranged in each case in the recesses 19a, 19b.
  • the sensing elements 20a and 20b have a rectangular shape, the long edges running in the width direction and the short edges running in the working direction corresponding to the edges of the cutouts 19a, 19b.
  • the outer end of the sensing element 20 extends approximately to the center line 1a of the feed roller 1 in the direction of the licker-in 3.
  • the sensing element 20 is on a holding member 21, for. B. stored a beam that has a pin-shaped projection 22 at one end.
  • a bore with a ball bearing 23 is present approximately horizontally within the sensing element 20, in which the pin 22 engages.
  • the sensing element 20 is rotatably mounted about a horizontal axis (see arrow A).
  • the holding member 21 is mounted on a fixed rotary bearing 23, so that the holding member 21 is rotatably mounted about a horizontal axis (see arrow B) which is perpendicular to the axis according to arrow A.
  • the sensing element 20 is movable in the vertical direction (see arrow C).
  • the holding member 21 interacts with a compression spring 24, which is attached at one end and becomes a fixed abutment. Furthermore, a measuring element 16 is arranged on the holding member 21, for. B. from a plunger 16 'and an inductive plunger 16''(inductive, non-contact displacement transducer / distance meter). 3b, 20 measuring elements 16a and 16b are arranged in the region of the two end faces below the sensing element. A stop 21a (see FIG. 3a) prevents the sensing element 20 from engaging in the clothing of the feed roller 1.
  • the sensing element 20 is supported in the area of the two ends (longitudinal end faces) by compression springs 25a, 25b arranged below.
  • the feed roller 1 is resilient (spring 26) and the dining table is fixed.
  • Fig. 5 shows a bearing of the sensing element 20, wherein the feed roller 1 is fixed under the dining table 2 resilient (spring 27).
  • the sensing element 20 has on its underside a support element 20a, the end surface of which is remote from the sensing element 20 and has an arcuate convex shape. This arc engages in a form-fitting manner in the arcuately concave recess of a support element 28 which runs between two vertical guides 29 (only one guide is shown in the drawing).
  • the support element 28 is supported on its underside by two springs 31a, 31b each against a stationary abutment.
  • the sensing element 20 is rotatable about a horizontal axis according to arrow A via the support element 20a and movably supported in the vertical direction according to arrow C via the support element 28.
  • the direction of rotation of the rollers of the card is indicated by curved arrows.
  • the invention was illustrated using the example of a card. It can be used in the same way for similar machines such as cards, striking machines, cleaners or similar machines.
  • FIG. 7 shows an embodiment in which two bearings 33a, 33b are arranged on the frame walls 32a, 32b, in which the feed roller 1 is rotatably mounted.
  • the dining table 2 is rotatably mounted in two bearings 34a, 34b via two connections 2c, 2e and 2d, 2f (see double arrow E).
  • the two bearings 34a, 34b are connected by a rigid, fixed axis 36.
  • the connections 2c, 2e are arranged rotatable about the axis 36 (double arrow E).
  • Two pipe sections 37a, 37b are arranged rotatably about the axis 36 (see double arrow B), each of which is connected to a holding member 38a or 38b.
  • a lever arm 39a or 39b is attached to the holding members 38a, 38b on one side, and a weight 40a or 40b is attached to each end.
  • the lever arms 39a, 39b opposite sides of the holding members 38a, 38b each have a lever axis 21a, 21b, which extend through a recess 2g or 2h in the dining table 2.
  • the sensing elements 20a, 20b are rotatably mounted about a horizontal axis (see FIG. 3, double arrow A).
  • a measuring arm 41a, 41b which is connected to the plunger armature 42a or 42b of the measuring element 16a or 16b, is attached to the jacket of the tube pieces 37a, 37b; each plunger 42a, 42b plunges into the associated plunger 43a or 43b.
  • a support element 44a or 44b is fastened, in each of which a plate spring 45a shown in FIG. 7b and a guide pin 46a shown in FIG. 7b for the plate springs are arranged.
  • the dining table 2 is thereby supported by the support elements 44a on the bearings 34a, 34b (cf. also FIG. 5 with support by helical springs 27).
  • the dining table 2 is movable. This is done in order to achieve the same possible contact pressure even with fluctuations in the thickness of the fiber material.
  • the pressure is high and is required for clear fiber material transport and for clamping the fiber material fed at the processing edge (feed roller 2 / licker-in 3).
  • the clamping prevents packets of fiber material from being torn out by the licker-in 3. This clamping determines the amount of pressure;
  • the fiber material transport is less important. From the point of view of fiber transport alone, the contact pressure should be somewhat less.
  • the pressure between the dining table 2 and the feed roller 1 is not used for measuring the fleece thickness. 7, the feed roller 1 is not movable (stationary).
  • the sensing elements 20a, 20b are movable and scan the fleece thickness against the stationary rotating feed roller 1 with very little contact pressure. This pressure does not serve to transport the fiber material, but is rather a hindrance to the transport of fiber material. Therefore, the pressure is set so weak that a clear Thickness detection is possible.
  • An essential idea is that, in view of the mutually contradictory dimensions and tasks, the greatest possible separation of functions has been carried out. This enables the individual tasks (in particular clamping of the fiber material at the processing edge and scanning the thickness of the drawn-in fiber material to be treated independently of one another and thereby be solved) better. This leads in particular to a more sensitive detection of the thickness fluctuations. This is the opposite of what is achieved when a function is combined.
