Definitions

  • the present invention relates to a textile carding apparatus for processing textile fibres, having a sliver coiler provided with suction means for removing dust and fly from a region within a hood thereof.
  • the carding machine comprises a main framework supporting a material feeding arrangement, a taker-in cylinder, a main cylinder with adjacent revolving or stationary flats, a doffing system and a sliver deposition apparatus in the form of a sliver coiling mechanism.
  • the function of the coiler is to receive the condensed web from the doffing arrangement and deposit it in sliver form into a sliver can or similar receptacle.
  • a cleaner material results and in this respect a material more suitable for feeding to the rotor of an open-end spinning machine is provided.
  • dust and trash are undesirable elements in spinning. Collection of dust within the spinning rotor can cause repeated end breaks and also contamination of the resultant yarn.
  • the sliver within the hood may pass over at least one rotatable sliver guide roller above the sliver coiling apparatus and around which the sliver is caused to divert in its passage to the sliver coiling apparatus.
  • the sliver coiler hood may be a double hood which includes an inner hood which is localised within the outer hood and is in the region of a coiler plate of the sliver coiler, the spaced support points defining the unsupported length of the sliver between the inner and outer hoods, and the suction being applied to a second suction means connected to the interior of the inner hood to remove dust and fly therefrom as well as to the first-mentioned suction means to the interior of the outer hood.
  • a carding machine doffing and coiling arrangement receives a web of fibres carded on a main cylinder 1.
  • This carded web 2 is taken from the main cylinder 1 by the doffer 3.
  • a roller doffing arrangement is then used to strip the carded web from the doffer 3.
  • This roller doffing 'arrangement comprises a doffing roll 4 with a blade 5 followed by a redirecting roller 6 and a pair of crush rolls 7 and 8.
  • the carded web is then removed by a belt doffing device 9 which compresses the carded web into a sliver 11 which is then further compressed by passing it through the trumpet guide 10.
  • This trumpet guide 10 leads the sliver 11 into the drawbox 12 which is indicated by dotted line in Figure 1.
  • the sliver 11 then passes through tongue and groove rollers 13 and 14 around the guide 15 and upwardly to a first grooved sliver guide roller 16 on to a second grooved sliver guide roller 17 and downwardly into a coiler 18.
  • the sliver is then coiled in conventional fashion and deposited into a sliver can 19 which is held stationary by retaining arms 20.
  • the sliver can illustrated is supported on castors 21.
  • an outer dust hood 22 is provided to inhibit dispersion of the dust and fly liberated from the sliver as it changes direction over the grooved rollers 16 and 17.
  • the outer dust hood 22 comprises a hollow casing of sheet material, which may, for example, by polycarbonate. This material is suitable since its antistatic properties deter the adherence of dust and fly to the surfaces of the hood and also because its transparency permits observance of conditions existing within the hood during operation. Alternatively the hood may be formed from sheet metal. A rim 23 of strip metal extends around the base of the hood 22 so as to give rigidity to the hood.
  • the hood 22 is attached to a casing 24 of the coiler 18 by a hinge 25 which permits the hood to be raised from the closed position as shown in the drawings to an open position so as to allow threading up of the sliver to the coiler.
  • a counterbalance device may be used to allow the hood 22 to be placed in an open, intermediate or closed position. In the closed position the rim 23 engages a raised stop 26 on an upper surface of the coiler casing 24 so as to provide an air inlet clearance 27 between the hood 22 and the casing 24 for a purpose hereinafter described.
  • the grooved roller 16 is mounted for free rotation on a bracket 28 and the grooved roller 17 is similarly mounted for free rotation on a bracket 29.
  • the brackets 28 and 29 are interconnected by a metal strip 30 and supported from the casing of the coiler 18.
  • the inner hood 38 comprises an upright side wall 39 which encircles the coiler plate 37 and is concentric therewith.
  • the side wall 39 is secured to the coiler casing 24 by a plurality of brackets 40 and is provided around its top edge with a seal 41. which may consist of felt or similar material.
  • a circular cover 42 extends over the coiler plate 37 and has a sliver inlet hole 43 at a position above the aperture 36 in the coiler plate 37.
  • the cover 42 is located with respect to the coiler plate 37 by a locating pin 44 fixed to the coiler plate 37. and projecting through a locating hole 45 in the cover 42.
  • Driving of the cover 42 in synchronism with the coiler plate 37 is effected by a setscrew 46 which passes through the cover 42 and screws into a stud 47 located in the coiler plate 37. Between the head of the setscrew 46 and the cover 42 is a spring 48 which lightly presses the cover 42 into contact with the seal 41.
  • the interior of the inner hood 38 is connected to the suction source 35 by an outlet pipe 49 which is formed so as to communicate through the coiler casing 24 with the duct 32.
  • an additional air inlet 50 may be provided in the hood 22 at a position on a side of the grooved roller 17 and the coiler plate 37 remote with respect to the outlet position of the hole 31.
  • airflow is created which flows from the air inlet 50 across the case of the cover 42 and out through the outlet hole 31 carrying with it dust and fly liberated from the sliver as it passes around the grooved rollers 16 and 17.
  • the raised stop 26 may be omitted so that the rim 23 rests on the coiler casing 24 whereby air is admitted to the hood 22 mainly through the air inlet 50.
  • the inner hood 38 may be used without the use of the outer hood 22, or, alternatively, the outer hood 22 may be used without an inner hood 38. However, particularly when processing heavily contaminated material, it is preferable to employ both the inner and outer hoods to achieve maximum cleaning efficiency.

Abstract

Un appareil de traitement de fibres textiles ayant un appareil de depot de ruban (18) est pourvu de moyens d'aspiration pour enlever les poussieres et le ploc que libere un ruban (11) dans son passage vers l'appareil de depot de ruban. L'appareil a enlever la poussiere et le ploc comprend un capuchon (22, 38), au travers duquel passe le ruban, et il s'etend sur une partie de l'appareil de depot de ruban et possede une source d'aspiration (35) connectee avec sa partie interieure pour enlever la poussiere et le ploc. Le capuchon est constitue d'un capuchon externe (22) enfermant un capuchon interne (38) situe dans la region de la plaque du pot tournant (37) et des moyens d'aspiration connectes a l'interieur du capuchon interne communiquent avec les moyens d'aspiration connectes a l'interieur du capuchon externe. Si on le desire, le capuchon interne ou le capuchon externe peut etre utilise separement.
