Abstract
Description
- This application is a continuation of pending U.S. application Ser. No. 09/747,433 filed Dec. 26, 2000.
- This application claims the priority of German Application No. 199 63 082.8 filed Dec. 24, 1999, which is incorporated herein by reference.
- This invention relates to a device for cleaning traveling flat bars circulating in a carding machine. The flat bars are mounted on an endless carrier supported on end sprockets which periodically reverse the direction of travel of the flat bars. At least at one region of reversal a chamber-like suction device is arranged which is coupled to a suction source and has a suction opening.
- In a known apparatus, as described in European Patent No. 0 366 948, to which corresponds U.S. Pat. No. 4,945,609, at one location of reversal, coaxially with the center of curvature, an elongated suction pipe is provided which is situated between the two end sprockets and extends along the width of the carding machine, that is, along the length of the traveling flats. At one end face the suction pipe terminates in a flange to be coupled to a suction source. A suction slot is provided in the suction pipe along the entire length thereof.
- The above-outlined prior art construction has the following disadvantages:
- The sole suction slot has only a slight suction effect. Further, the suction pipe is an additional structural component which is difficult to install in the zone of reversal where the sprocket drive shaft is positioned, thus rendering the apparatus complex and expensive. To avoid undesired air flows and to reduce the air consumption, additional measures are required such as the provision of sealing lips mounted on the back of the flat bars for sliding on the suction pipe. Also, the coupling to the suction source must be guided around the traveling flats sprockets.
- It is an object of the invention to provide an improved apparatus of the above-outlined type from which the discussed disadvantages are eliminated and which, in particular, is simple to construct and assemble and results in a better cleaning efficiency.
- This object and others to become apparent as the specification progresses, are accomplished by the invention, according to which, briefly stated, the carding machine includes a traveling flats assembly which has a plurality of flat bars traveling in an endless path. The flat bars are spaced from one another in a travel direction thereof. First and second end rolls periodically reverse the travel direction of each flat bar. At any time a plurality of flat bars are situated in a circular array on each end roll for being carried in a circular path thereby. First and second drive shafts carry and rotate the respective first and second end rolls. An apparatus for cleaning the flat bars is arranged in a region of at least the first end roll. The apparatus includes a throughgoing, eccentric aperture provided in a radial wall of the first end roll. At any time at least two mutually adjoining flat bars, situated on the first end roll, are aligned at least partially with the aperture. A suction inlet adjoins the radial wall of the first end roll for being periodically brought into alignment with the throughgoing aperture upon rotation of the first end roll. A suction chamber is formed by a space bounded by the adjoining flat bars and a peripheral surface of the first drive shaft.
- By providing a vacuum chamber formed by adjoining outer surfaces of the flat bars and the drive shaft, that is, already existing structural elements are being utilized, the structural and mounting outlay is significantly reduced as compared to prior art arrangements. A suction chamber provided in this manner has a small cross section whereby a higher flow velocity is achieved which, in turn, leads to an increased cleaning effect. The suction source may be arranged without spatial problems at the outer side of the end sprocket and may draw air in this manner through the suction openings. Further, advantageously, the tooth gaps of the end sprocket may be exposed to a suction stream and may thus be cleaned.
- FIG. 1 is a schematic side elevational view of a carding machine incorporating the invention.
- FIG. 2 is a side elevational view of an end region of traveling flats at the frontal end sprocket.
- FIG. 3 is a side elevational view of the rear end sprocket of the traveling flats.
- FIG. 4 is a sectional top plan view of one part of the construction shown in FIG. 3.
- FIG. 5 is a perspective view of an end sprocket including five through openings exposed to a suction stream.
- FIG. 1 shows a carding machine CM which may be, for example, a DK 903 high-performance carding machine manufactured by Trützschler GmbH & Co. KG, Mönchengladbach, Germany. The carding machine CM has a feed roll1, a feed table 2 cooperating with the feed roll 1, licker-
ins doffer 5, astripping roll 6, crushingrolls web guiding element 9, asliver trumpet 10,calender rolls traveling flats assembly 13 having slowly circulatingflat bars 14 which move approximately at between 0.05 and 0.4 m/min. Theflat bars 14 are at opposite longitudinal ends thereof coupled to respective, non-illustrated, parallel-arranged endless circulating belts trained about end rollers, such as end rolls (end sprockets) 13 a, 13 b. Also referring to FIG. 2, theflat bars 14 are pulled by the belts in the working direction A over non-illustrated bends and they reverse direction by means of the end sprocket 13 a rotating in the direction D and continue their travel in the idling direction B. Then the end sprocket 13 b, rotating in the direction C once again advances theflat bars 14 in the working direction A. The direction of rotation of the rolls of the carding machine are shown by curved arrows drawn therein. At the outlet of the carding machine CM asliver coiler 16 is positioned for depositing sliver into the coiler can 16′. On the return travel side theflat bars 14, as they move in the idling direction B, are exposed to slowly rotatingflat bar brushes 17 for cleaning theflat bar clothings 14′. Theflat bar brush 17 cooperates with a rapidly rotatingcleaning roll 18. Asuction device 19 draws debris, dust, short fibers and the like from the inner space underneath thecover 20 of the card. - According to FIG. 2 the
frontal sprocket 13 b (as well as the non-illustrated other frontal sprocket supporting the other belt connected with the respective opposite longitudinal ends of the flat bars 14) has five circumferentially distributed throughgoingelongated openings 21. On the outer circumferential surface of the drive shaft 22 a yielding cylindrical jacket 23 (made, for example, of foam material) is arranged. The outer surface of the jacket 23 is in airtight engagement with theback face 14″ of thoseflat bars 14 which, during the course of their travel, are situated on thesprocket 13 b. By virtue of this arrangement, the suction chamber between two adjoiningflat bars 14 has narrow limits and has a small volume. - FIG. 3 shows the same arrangement for the rear belt sprocket13 a and is duplicated for the other, non-illustrated rear belt sprocket at the opposite end of the flat bars. As also shown in FIG. 4, the inlet opening of a
suction pipe 25 is located close to the outer face (radial wall) of the sprocket and is aligned with theelongated openings 21 as they pass by. The inlet opening of thesuction pipe 25 is situated in the region where the direction of travel of the flats is reversed and draws air through thesprocket 13 a′ of the traveling flats drive. Thus, as it may also be observed in FIG. 2, the suction chamber 15 is composed by twoadjoining flats bars 14 1 which at least partially extend within the outline of the inlet opening of thesuction pipe 25 and the jacket 23 surrounding thesprocket drive shaft 22. Since the locations of suction have a small cross section, a high flow velocity is obtained. As the end sprocket rotates, the location of suction is closed in the intermediate traveling bar space and thus the soiled sprocket tooth gaps are exposed to suction. Asuction nipple 25 is coupled to a non-illustrated suction source. Anadjustable setting flange 26 is affixed to thesuction nipple 25 and is mounted on the frame of the carding machine. - Particularly referring to FIGS. 2, 3 and4, the
suction nipple 25 of the suction source immediately adjoins the outer side of the end sprocket 13 a. The suction chambers 15 1, 15 2 are formed essentially by thedrive shaft 22 and the space between the outer faces of any two adjoiningflat bars 14 1 which are simultaneously at least partially within the outline of anopening 21 and, at the same time, are located within the outline of thesuction nipple 25. - Thus, as the end sprocket13 a and/or 13 b associated with a suction arrangement according to the invention rotate, consecutively different suction chambers 15 arrive into the region of the
suction nipple 25 whereby the dust laden air (arrow E in FIG. 4) is drawn from the suction chamber 15 (see FIG. 3) through the elongated end sprocket opening 21 into thesuction nipple 25. FIG. 3 furthermore shows that thetooth gaps 24 between the teeth of the end sprocket are also exposed to suction and are thus cleaned. - By virtue of the non-continuous mode of operation, a vacuum fluctuation is obtained. This prevents, among others, an adherence or winding of the fibers on the structural components such as the
sprockets 13 a and/or 13 b, theflat bars 14 and the flat bar drive belts. - FIG. 5 shows in perspective view one
end sprocket 13 b according to the invention to more clearly illustrate thetooth gaps 24 between adjoining sprocket teeth and the fiveelongated suction apertures 21. The drive shaft not shown in FIG. 5 is adapted to pass through thecentral sprocket opening 27. - The suction may take place bilaterally on the right and left-hand side of the machine or may be effected only at a single machine side. Preferably such a suction is effected from the left-hand machine side since there the drive need not be circumvented. In case of a bilateral suction structure, in the middle of the suction chamber normally a dead spot would be formed which, however, is eliminated due to the fluctuating suction according to the invention. In case of unilateral suction on the other side, the suction stream may advantageously be enhanced by air pressure pulses in which case the
component 25 is, at such other side, functioning as a pneumatic pressure outlet. - It will be understood that the above description of the present invention is susceptible to various modifications, changes and adaptations, and the same are intended to be comprehended within the meaning and range of equivalents of the appended claims.
