Device for breaking small impurities in card slivers formed by a card

The invention relates to a device for breeding the small ones Impurities that are present in card slivers coming from a carding machine, for example those found in cotton card slivers Impurities.

In connection with devices of the type mentioned, it has long been known that small contaminants, such as pieces of seed coats cored cotton, small particles of capelet and similar small fragile impurities thereby from the fiber material can be removed that they are broken while the fiber material is delivered in tape form from the card. Of the Peralta rollers, which are usually used in wool cards and sometimes also in cotton cards, are known to have such Break down impurities which are removed during subsequent processing, for example during spinning, drawing and the like.

BATH ORIGINAL

There are ready devices for breaking the contaminants of a calibrated card sliver has been proposed and in use One of the problems encountered with such devices is building them sufficiently separately that they can be integrated into the original Overall outline of the clutter itself will fit. Furthermore, it is very desirable in this type of device that the crushing roller weighting or loading device · !! a fixed immutable Exert load on the crushing roller »by a smooth To exert pressure over the length of the same · This problem has not yet been solved in a satisfactory manner · Furthermore, should sometimes the clutter operated without the use of such Breehwalsen can be. In some known devices, means are provided by which only the pressure on the upper The crushing roller is lifted without this · being lifted · In another known device, the upper orphan does not always become so returned that the exact and desired operating pressure as before the increase is reached again.

The main object and some subordinate objects of the invention are

the following·

(1) The creation of a device that can be attached to existing cards and is designed in such a way that the overall length the clutter is not coarsened, making it a machine of compact design »with which valuable floor space of the company can be savedi 909842/0538 -2-

(la) in connection with the Hauptsiel after (1) in the creation of a Device of the type mentioned, in which the orphans below the swinging comb of the clutter are arranged}

(Ib) in connection with the goal naoh (1) the arrangement of the Breohwalsen both below the Kane and very close to the customer and in such a situation that the course or the normal Path of the ribbon directed towards and into the gap of these orphans iatj

(2) the creation of a susceptible leverage to exert pressure on top of the orphans with a floating knife edge look, which serves to maintain a constant lever arm length under all operating conditions. Such a Arm has the advantage that it is practically frictionless and essentially no reinforcement errors due to wear and tear of the Parts enter;

(3) the provision of an apparatus of the type mentioned in which the lower crusher roll is mounted in pivotable bearings at each end, and gowns are provided through which these lower roller can be precisely adjusted and held in the adjusted position with respect to the upper orphan. This setting option leaves a compensation for manufacturing deviations in the orphans or other parts of the device as well as a Equal for the wear of the rollers or other parts too;

(4) the creation of a breaking device for cotton card slivers and the like, the 80 is formed that a negative mechanical Pull exerted between the Abnenmerfleche and the crushing rollers

909842/0538 -3.

«Can earth. This has the advantage that "when the device according to the invention is installed in an existing card it is not necessary to replace one of the Streokwerk gear wheels or any of the other gear wheels" which drive the consumer with respect to any other part of the device;
(5) the creation of a cleaning board on the uppermost orphan and in connection with this a small elongated trough "which is arranged at a small distance τοη the orphan and slightly below the cleaning board, so that lumps or bulbs" fall off the put board "into the Trough from which they are removed, which avoids that the tape is contaminated by such lumps or tubers) the creation of a swiveling put board for the entere catfish to which a plate is assigned, which is positioned down between the operator and extends to the doffer and has the dual function of preventing the operator's fingers from being pinched between the lower roller and the doffer, and also serves as a handle by means of which the cleaning board can be pivoted away from the lower orphan for cleaning ; the creation of a safety bar, which is arranged immediately above the nip of the Breoh rolls and below the belt that is brought up "in such a way" that this bar extends outside the belt's track "

On the sides of the end plates 17, pins 16 protrude outward bearing housings 19 are pivotably arranged in these journals * In these Bearing housings are bearing 21 arranged, the srnr rotatable bearing serve a shaft 22, which carries the upper belt breaking roller 2J.

The housing of the lower crushing roller are provided with old arms 31. At the outer ends 52 of these arms are supported by adjusting screws at the top and bottom 33, which are screwed into a corresponding part of the end plates 17. By adjusting the screws 33 with Be-SUg one another, the entire bearing housing 26 can be pivoted around the pin 24 in order to lift or deflect the roller 29 and thereby approaching the upper roller 23 or moving it away from it.

They bearing housings 19 are provided in a similar manner with arms 34, as can be seen in particular in FIG. They outer ends of the Arms 34 carry hardened blocks 36 that have one on one edge

Wedging pins 39 are driven into the ends of the arms 34, which have a conical head 41. Floating sharp-edged pressure member blocks or plates 42 are arranged above the pins 39 and held against outward movement by the head 43. The blocks 42 are, as mentioned, seen with sugeso-sharp edges 43 ▼, one of which is in the V-shaped recess 37 of the Blocks 36 and the other blocks 46 hardened in a V-shaped recess 44 sitst, which latter duroh screw caps 47 on attached to the ends of weighting arms are indicated generally at 48.
