Definitions

  • the present invention relates to the field of the textile industry, and relates to an improvement made to the recovery means of the rolls of a card.
  • a card has a plurality of cylinders which are supported by a carrier frame. At least one of these cylinders is a carding cylinder which is more commonly referred to as a "big drum” and which is provided with a carding insert. At the periphery of this carding cylinder and at the top are mounted satellite carding members. Some cards may have several successive carding cylinders.
  • Carding organ structures are diverse, and vary depending on the type of card.
  • the carding members are constituted by one or more successive carding groups, each carding group consisting of a first roller commonly called “worker” associated with second roller commonly called “stripper” or “Sweeper”.
  • the carding members may be in the form of a fixed upper work element (also called “carding plate”) having a plurality of fixed carding points at the periphery of the carding cylinder.
  • the fibers are introduced at the entrance of the card in the form of a fiber mat, and are individualized at the periphery of each carding cylinder (carding action) by the combined actions of the carding members and the carding member. peripheral packing of the carding cylinder.
  • a card also has other cylinders such as example of the sail forming cylinders which are arranged downstream of the last carding cylinder.
  • sail formation cylinders are usually and mainly the so-called “dough” cylinders, the so-called “condenser” cylinders, and the so-called “counter-drum” cylinders.
  • these covering means delimit a protective enclosure inside which are housed the cylinders of the card.
  • these covering means generally consist of two side walls fixed to the ground and interconnected by at least one upper wall. This enclosure makes it possible both to protect the cylinders against elements external to the card and to prevent the flying fibers that have escaped from the cylinders from dispersing in the surrounding air. It is also customary to use, in combination with these covering means, a forced circulation of air from the inside to the outside of the enclosure formed by the covering means, for example by means of a fan, for example for the purpose of taking up and evacuating the flying fibers.
  • the implementation of the covering means poses a problem of accessibility to the card rolls. Now it is essential that the user of the card and the personnel responsible for carrying out the maintenance or repair operations of the card can have physical access to the card rolls the easiest and most quickly possible. To date, this access is made possible for example by providing, in the upper wall or in the side walls of the covering means, doors or movable or removable access doors, which is not satisfactory from one point. view of speed and ease of access.
  • the present invention aims at proposing a new technical solution to the problem of access to the rolls of a card comprising means for covering said rolls. More particularly, the invention aims to provide a solution that allows quick and easy access to at least a portion of the rolls of the card, and preferably to all the cylinders of the card.
  • the invention relates to a new card, which is known from the prior art in that it comprises a plurality of cylinders and covering means for forming a chamber in which are housed the cylinders of the card; the card of the invention is characterized in that the covering means comprise at least one covering element which is movable in translation.
  • At least one covering element is movable in translation along an axis perpendicular to the longitudinal direction of the rolls of the card.
  • the attached figures show a card comprising a set 2 of cylinders (20, 21, .%) that are substantially parallel, and covering means 1 which delimit a protective enclosure E within which is housed the assembly 2 of cylinders (20, 21, .).
  • the set 2 of card rolls is known per se and will therefore be very briefly described. It comprises from the inlet to the card outlet: a food roll 20, a cylinder 21, a first rotary carding cylinder 22, more commonly called a front-end, a transfer cylinder 23, still commonly called a “communicator”, a second carding cylinder 24, commonly called “large drum”, sail forming cylinders 25 and 26 (for example rollers of the doffer or condenser type) each forming a carding outlet.
  • several planet gears 27 are mounted at the periphery and in the upper part of the front end 22 and the large drum 24, each carding unit 27 being composed of a sweeping roller 27a and a working roller 27b.
  • This set 2 of cylinders (20,21, 7) makes it possible to manufacture in parallel two non-woven webs, for example based on synthetic fibers of the polypropylene, polyethylene, ... type, and / or natural fibers of the type cotton, and / or viscose-type artificial fibers, ...
  • the set 2 of card rolls (20, 21, ...) of the appended figures is given by way of example only, and is not limiting of the invention.
  • the covering means of the invention can indeed be used with any possible configuration of set of card rolls.
  • the invention can be implemented not only on any type of nonwoven card, but also on any type of wool card.
  • the covering means 1 are made according to a preferred embodiment of the invention which will now be detailed.
  • the covering means 1 consist of four individual covering elements 10, 11, 12, 13 distinct.
  • each individual covering element 10, 11, 12, or 13 comprises two vertical lateral walls V, arranged on either side of the card rolls and an upper wall. H connecting the two side walls V.
  • each wall H, V is translucent at least on a portion of its surface, so as to allow a visual inspection of the cylinders from the outside, when all the covering elements are in their position closure.
  • Each individual element 10, 11, 12, 13 is for example constituted by a frame 10a, 11a, 12a, 13a (FIG. 2) which is formed of an assembly of metal sections and on which glass panels are fixed or translucent plastic 10b, 11b, 12b, 13b.
  • Each covering element 10, 11, 12, 13 is movable and individually guided in translation relative to the ground along an axis MD (FIG. 1) which is perpendicular to the longitudinal direction CD of the rolls (20, 21, ...) of the card (direction CD parallel to the longitudinal axes of the cylinders).
  • FIGS. 2 and 3 illustrate an exemplary embodiment of the means used for the guided translation of each covering element 10, 11, 12, 13.
  • each covering member 10, 11, 12, 13 comprises, at the lower edge of its side walls V, rollers R mounted free in rotation, and cooperating with a raceway. More particularly, this raceway consists of a rectilinear guide rail R ', which is fixed to the ground, being oriented parallel to the translation axis MD of the covering elements.
  • Each covering element 10, 11, 12 13 is placed, by means of its rollers R on two guide rails R ', which are specific to it, and which are fixed parallel to one another on the other hand and other cylinders of the card, and can thus roll on these two rails R 'being guided in translation.
  • the invention is not limited to the above-mentioned rolling structure of the type of wheels R / guide rails R ', but can be implemented with any equivalent means fulfilling the same function, that is to say with any means allowing translational guidance relative to the ground of each covering element.
  • the rolling means (R, R ') may for example be replaced by slide-type sliding means.
  • FIGS. 1, 2 and 4 show the covering elements 10, 11, 12, and 13 when they are each in their first extreme so-called covering position.
  • the covering elements 10, 11, 12, 13 are substantially juxtaposed along their MD translation axis, and delimit the aforementioned protective enclosure E.
  • the covering element 10 In its covering position, the covering element 10 covers the cylinders 20, 21, substantially an upstream half of the first carding cylinder 22, and the carding groups 27 at the periphery of this upstream cylinder half 22.
  • the covering element 11 covers the other downstream half of the carding cylinder 22 and the carding unit 27 at the periphery of this other downstream cylinder half 22, the communicating cylinder 23, substantially an upstream half of the second carding cylinder 24, and the rollers of the carding groups 27 at the periphery of this upstream cylinder half 24.
  • the covering element 12 In its covering position, the covering element 12 covers the other downstream half of the carding cylinder 24 and the rollers of the carding groups 27 at the periphery of this other downstream half of the cylinder 24, almost all of the formation cylinder. lower sail 26 and substantially an upstream half of the upper sail forming cylinder 25.
  • the covering element 13 covers the other downstream half of the upper sail forming cylinder 25.
  • the upper walls H of the covering elements 10 and 11 are curved so as to follow as closely as possible the cylinders which are covered by these elements 10 and 11 in the covering position.
  • FIG. 6 shows the covering elements 10, 11, 12, and 13 when they are each in their second extreme position called opening. In this configuration, all the cylinders of the card are discovered, and are thus advantageously very easily accessible.
  • each covering element 10, 11, 12, 13 is equipped with at least one handle or equivalent (not shown) which is fixed on one of its side walls (V).
  • the two covering elements 10 and 11 which have the same direction of opening are designed in such a way that the central covering element is able to completely cover the other covering element. 10, especially when the two elements 10 and 11 are in their open position. It is the same for the two covering elements 12 and 13 which have the same direction of opening (direction D), the central covering element 12 being able to completely cover the other covering element 13. of this solution, the guide rails R 'of the covering element 10 (respectively 13) are offset in position relative to the guide rails R' of the covering element 11 (respectively 12) .
  • the covering elements 10 and 11 when in their open position, advantageously occupy substantially the same space on the ground as a single element 11 (respectively 12), which makes it possible to minimize the bulk of the covering elements.
  • the covering element 11 in the extreme open position, completely covers the covering element 10 (respectively 13). In another variant embodiment not shown, the covering element 11 (respectively 12) could cover only part of the covering element 10 (respectively 13).
  • FIGS. 7 to 9 differs from the variant of FIGS. 1 to 6 in that the individual covering elements 12 and 13 above have been replaced by a single covering element 12 'that can move in translation along the axis. MD (opening direction D). Also in this variant, at least one of the vertical side walls of this covering element 12 'comprises two panels P1 and P2, one of which P2 is preferably pivotally mounted relative to the other P1, by means of hinges (FIG. 8).
  • the invention is not limited to the preferred embodiments of the appended figures. In the more general context of the invention, it will be possible, in particular, to provide covering means comprising a different number of individual covering elements. Also, in the simplest variant embodiment, the card could have only one movable covering member in translation and dimensioned so as to cover, in its covering position, all the cylinders of the card.
