Definitions

  • the present invention relates to an apparatus for feeding fuzzy thread for chenille machines.
  • chenille which generally comprise more chenille-forming lines or "axes" each of which comprises a unit for feeding interweaving threads, a unit for feeding and cutting the fuzzy thread, and a unit for twisting and collecting the yarn.
  • Patents Nos. EP 502.282, 396881 and EP 674.030 describe machines for producing chenille which include the devices mentioned above.
  • the chenille is produced by twisting two so-called “interweaving” threads, with a third, so-called “fuzzy” thread interposed therebetween.
  • the fuzzy thread is spiral-like wound onto a gauge which has a notch for receiving a blade performing the cutting of the turns into lengths of preset extension.
  • the interweaving threads are fed laterally with respect to the gauge so as to engage and retain the lengths of thread after said twisting operated by means of spindles on which the thus produced yarn is collected.
  • the gauge is associated with a corresponding support able to be fixed to the machine's structure at a preset point thereof.
  • a drawback related to this known system lies in the fact that the positioning of the gauge, that is, the disposition of the latter, changes in the course of the production, because of the vibrations which inevitably this type of machine is subjected to, the possible constructive faults of the gauge's support and of the thermal gradient as well provided by the work environment of the machine.
  • the gauge's displacements with respect to the ideal operating position which should be all the time in a most accurate positional relationship with the fuzzy thread's feeder, may bring about serious inaccuracies in the dimensioning and cutting of the relevant turns and, accordingly, a progressive impairment in the quality of the finished product.
  • the main object of the present invention is to overcome the said drawbacks. This result has been achieved, according to the invention, by providing an apparatus having the characteristics indicated in claim 1. Further characteristics being set forth in the dependent claims.
  • the present invention makes it possible to keep the gauge in a precise and steady positional relationship with respect to the fuzzy thread's feeding means, so that the quality of the finished product results constant throughout the manufacturing cycle. Moreover, an apparatus according to the invention is relatively easy to make, cost-effective, and reliable even after a prolonged service life.
  • an apparatus comprises an electric motor (M) with the longitudinally hollow shaft (1).
  • the longitudinal cavity of the shaft (1) is intended for guiding the fuzzy thread which enter from the top (arrow "F” in Fig. 1) and comes out laterally through a hole (100) formed across the same shaft (1) at a preset distance from the inlet hole (10).
  • the guide for the fuzzy thread may also consist of a pipe (2) located within the longitudinal cavity of the shaft (1) and provided with openings in correspondence of said holes (10) and (100).
  • the skirt (11) of the motor (M) can be made solid to the frame (not shown) of a machine for chenille by means of a fixing plate attached at the back of the same skirt (11).
  • Numerals (13) and (14) indicate the inner components of the motor (M) which is known per se.
  • the shaft (1) is borne by an upper bearing (15) and a lower bearing (16).
  • the upper bearing (15) is received in a corresponding seat formed in a flange (17) fixed to the upper base of the skirt (11).
  • the lower bearing (16) is received in a seat (42) exhibited by the element (4) described later on.
  • the present apparatus has a gauge (3) solid to the lower base of said skirt (11), that is, solid to the base of the skirt (11) opposite to the section for the admission of the fuzzy thread.
  • an anchoring element (4) attachable to the lower base of the said skirt (11) by screw means, and which has a central hole (40) for the shaft (1) to pass therein, the latter having such a length as to go beyond the element (4).
  • the said element (4) is also provided with a plurality of holes (41) allowing it to be fixed to the skirt (11) of the motor (M) by means of corresponding screws.
  • Solid to said element (4) are a number of magnets (50).
  • the said magnets (50) can be housed within suitable seats (51) formed in a cup-like cage (5) fixed to said element (4).
  • the said cage (5) has a plurality of holes (52) for its attachment to the base of the element (4), which base, in use, results oriented downwards.
  • the said cage (5) also exhibits a central opening (53) for the passage of the shaft (1).
  • the present apparatus comprises, in addition, a rotary feeder for feeding the fuzzy thread (6), said feeder being in the shape of a cup and provided with a central hub (60) to be keyed onto the lower part of the shaft (1) and with a straight channel (61) whose inlet section (610) is in correspondence of the opening (100) of shaft (1) for the exit of the fuzzy thread.
  • the said channel (61) is formed in the base (62) of the feeder (6) which, when in use, results facing upwards.
  • the outlet section (611) of channel (61) results therefore eccentric with respect to the longitudinal axis of shaft (1).
  • said channel (61) makes up an eccentric extension of the fuzzy thread's guide inside the shaft (1).
  • Housed in the space (63) internally delimited by the side surface of the cup (6) is a second set of magnets (70) having polarity opposite to that of the magnets (50) previously mentioned.
  • the magnets (70) of the second set are received within suitable seats (700) of a support (72) located inside said space (63) in a way that no contact will exist between the surface of element (6), which delimits the space (63), and the same support (72).
  • Both the support (72) of magnets (70) and the flange (7) exhibit a central opening (720; 74) for the passage of shaft (1).
  • the flange (7) is engaged with the shaft (1) by means of bearings (73), so that the rotation of the shaft (1) does not imply the corresponding rotation of the flange (7) and of the above-standing support (72) of lower magnets (70).
  • the gauge (3) is fixed to the lower base of the flange (7) which is associated with the support (72) of lower magnets (70). This can be achieved by using the element (8) shown in Figs. 4A-4C of the attached drawings.
  • the said element is provided with a base of annular shape, with a step element (81) able to be inserted into the space (71) internally delimited by said flange (7), and with a pair of diametrically opposite holes (82) to allow the fixing of same base to the flange (7) by means of two screws.
  • the element (8) has a slit (83) on the side opposite to the step (81). Going through this slit is the shank (30) of the gauge (3) to be steadly attached by a screw going through a hole (84) extending orthogonally to the slit (83). The latter being in line with the axis of shaft (1).
  • the gauge (3) results solid to the skirt of motor (M), that is, fixed at a predetermined position with respect to the fuzzy thread-feeding system.
  • the element (8) supporting the gauge (3) is fixed to the flange (7), which is magnetically attached to the cage (5) because of the magnetic coupling of magnets (50) and (70), and the cage (5) is solid to the skirt (11) of motor (M) via the anchorage (4).
  • the feeder is free to rotate, driven by the shaft (1) between the bodies (5) and (7).
  • the fuzzy thread comes out laterally of the feeder (6) and winds up over the gauge (3), thereby forming the turns to be cut in lengths.
  • the cut of turns is operated by a blade (not shown in the drawings) located at the bottom of the gauge, in correspondence of the notch (31) formed by the two sides (32) of the same gauge.
  • the lengths of fuzzy thread are successively engaged with known procedures by the interweaving threads fed by draw rollers and twisted by spindles normally provided in the machines for chenille.
  • draw rollers 9 is shown in Fig. 2.
  • the body (5) visible in Figs. 1, 2, 3 and 5 is a safety shield (S) hooked up to the skirt (11) of motor (M) by means of screws to which it is possible to anchor the arms (BS) of same shield (S) so that the latter will result on a side opposite to that of plate (12).
