  • These modular creels can form frames of various sizes, which may or may not be ventilated. However these structures have large dimensions, both vertically and horizontally .
  • the Applicant is the proprietor of European Patent EP2501634 relating to a modular element for creels having a structure in the shape of a polygonal solid provided with a support for a bobbin or spool of yarn; the structure comprises a yarn feeder to feed the yarn unwound from the bobbin with a parameter, either the tension or velocity of the yarn, that is held constant and equal to a predefined value (or function of the operating stage of the textile machine to which the yarn is directed) .
  • This structure can be modularly coupled to similar structures so that several yarns can be fed to such a machine, each yarn being able to have its own parameters defined by the feeder which passes it to the textile machine.

  • the bobbin supports are fixed.
  • JP04286574 describes a creel supporting several bobbins with yarn connected in a head-to-tail manner .
  • JP02234949 describes a yarn feed device comprising a vertical support bearing a plurality of arms which project at right angles, as therefore do the bobbins of yarn on fixed pins.
  • the arms can be rotated about the vertical support through suitable motors.
  • US2483160 describes a modular element for a creel comprising a frame having a support to support two or more bobbins whose yarns are connected in a head-to-tail manner.
  • the modular element can support several similar frames so that several yarns can be fed to a textile machine.
  • Each bobbin support can rotate about a pin of a supporting arm.
  • supports have pins which can move about a hinge capable of supporting corresponding bobbins. The movement of such pins is brought about manually .
  • the object of this invention is to provide a modular creel element which is nevertheless improved with respect to the known solutions.
  • one object of the present invention is to provide a modular element for a creel of small size through which it is possible to set up creels in such a way as to manage a large number of yarns, and through which it is possible to simplify and speed up the replacement of bobbins which have been emptied of yarn with full bobbins.
  • Another object of the invention is to provide a modular creel element through which it is possible to automate the operations of replacing empty bobbins with new bobbins loaded with yarn.
  • Another object is to provide a modular creel element through which it is possible to track the consumption of yarn and consequently to manage yarn processing in an optimum way.

  • the set of structures 2 may comprise a matrix or "molecular" structure where the individual "atoms" comprise structures 2 coupled together.
  • Structure 2 comprises at least one support 6 provided with arms 7, each to support at least one corresponding bobbin B.
  • arms 7 In the figures there are four arms 7.
  • Bobbins B supported on arms 7 present the corresponding yarns connected together in a "head-to-tail” manner, that is the start of the yarn from one bobbin B is connected to the "tail” or end of another bobbin B.
  • arms 7 project from and are attached to a common load-bearing portion 8 attached to rear face 2B of structure 2 and located parallel to such (vertical) face 2B.
  • the four arms 7 are arranged at 90° to each other and load-bearing portion 8 of support 6 is in turn attached to cross-member 3B.
  • Coupling is achieved in such a way that support 6 can rotate about an axis W at right angles to face 2B and cross-member 3B.
  • axis W is horizontal and perpendicular to vertical face 2B of structure 2.
  • an actuator which may be an electric or pneumatic motor of one piece with cross-member 3B and having an output or "motor” shaft to which support 6 is attached through its load-bearing portion 8. Operation of the actuator, for example the electric motor, brings about rotation of "revolving" support 6 about axis W along which the output shaft of the abovementioned electric motor lies.
  • an "antiballoon" disc 8K which prevents yarn F from a bobbin B passing beyond support 8 in the event of a pull or tension anomaly, and for example reaching the actuator, preventing it from operating correctly.
  • Disc 8K is of one piece with arms 7, but the latter project beyond that disc (see figures) .
  • Each arm 7 supports (at a free end thereof or close thereto) a body 11 which is rotatably fixed to corresponding arm 7 or each body 11 is hinged (in a known manner) to said arm at one proximal extremity thereof 11A.
  • bodies 11 can move between a first operating position corresponding to a position which they adopt when a yarn is fed to a textile machine (drawn from one of bobbins B) ( Figure 1), and a loading position in which they are rotated outwards from structure 2 ( Figures 3-5) .
  • the empty bobbins in practice tubular supports 15 on which the yarn sent to a textile machine was wound
  • full bobbins are advantageously associated with rear face 2B of structure 2 and inserted on fixed pins 16 fixed to sections 3 bounding aforesaid face 2B. This makes it possible to have full bobbins for loading onto bodies 11 when the bobbins placed upon them are empty.
  • Figures 3, 4 and 5 show the stages of detaching a support 15 from corresponding body 11 ( Figure 3), the removal of a full bobbin from corresponding pin 16 and the insertion of that bobbin onto said body 11.
  • a plurality of bobbins B is present within structure 2 and is supported by arms 7 of support 6; however it is only from one bobbin, for example that indicated by B100 in Figure 3, that yarn F is unwound and delivered to a textile machine (not shown) .
  • the yarn passes over wheels or rollers 40 (which rotate and guide yarn F without generating friction forces on it) and a feed device 50 (advantageously capable of maintaining a constant tension and/or speed and/or quantity of yarn F delivered to the textile machine) , said device being in itself known and being associated, with wheels 40, with a section or bar 60 which is of one piece with a vertical section 3 of structure 2, but at right angles thereto.
  • such bar 60 is of one piece with section 3A and lies in the axis W about which "revolving" support 6 rotates in order to minimise the angle which yarn F makes with feed device 50 and wheels or rollers 40, as any angle is a source of friction; reducing said angle in fact means that the tension of yarn F entering the feeder is reduced, or, better, that every possible variation in such tension, which is added to that of the yarn being unwound from bobbin B100, is reduced.
  • section or bar 60 can move along section 3A so that its height can be adjusted in relation to the point of entry of the yarn into the textile machine; this adjustment makes it possible to achieve an ideal guide as a result of which friction and tension on yarn F entering the machine is limited. This also makes it possible for the angle at which the yarn leaves bobbin B100 towards feed machine 50 not to be altered .
  • rollers 40 associated with (moving) section or bar 60 and at least one roller 90 (two are shown in the figures, see Figure 8) attached to (fixed) section 3A help to stabilise the tension of yarn F entering feed device 50, regardless of the angle which yarn F makes with bar 60.
  • the pair of rollers 90 (or “the at least one roller 90") is placed at a height on section 3A which is central with respect to support 6, corresponding to the focal point for unwinding yarn from the bobbin.
  • yarn F leaves section 60 at a right angle, but it can leave it at any angle.
  • Bodies 11 are inclined: downwards, those which support the waiting bobbins such that these bobbins B remain in a stable position on the projections, supported by gravity.
  • Bobbin B100 is instead inclined downwards to facilitate release of yarn F.
  • arms 11 are inclined towards each other to assist the unwinding of yarn, which is connected head-to-tail between the bobbins .
  • Feed device 50 is preferably of the type capable of feeding yarn to the textile machine continuously or discontinuously, at a constant tension and/or velocity and/or in a constant quantity. Control is brought about by device 50 itself. Obviously the latter can be placed in another position on structure 2.
  • Element 1 also comprises at least one sensor 88 connected to a control unit and acting on the yarn to detect the unwinding of yarn F from bobbin B100 moment by moment, and checking when it has run out.
  • this sensor 88 is located close to roller 90 and is associated with section 3A (see Figures 1, 2 and 8) .
  • the sensor is for example of the type described in EP2635925 and makes it possible to determine from which of bobbins B associated with support 6 the yarn is coming. In this way, when one bobbin is empty and the yarn comes from a different adjacent bobbin sensor 88 can detect the change in origin of the yarn with the consequences which will be indicated below.
  • sensors 88 are directly associated with support 6 (for example of one piece with disc 8K or arms 7) and are located between each pair of bobbins B associated with that support .
  • Sensors 88 act together with the tail of the yarn from a first bobbin connected to the head of the yarn from the (second) adjacent bobbin so as to detect immediately when the yarn from the first bobbin runs out and initiate delivery from the second bobbin.
  • Each sensor 88 (active or cooperating with the yarn being unwound) therefore generates a signal representing the unwinding of the yarn, a signal which is sent to the control unit (not shown) .
  • This control unit can be incorporated in feed device 50 and be connected to a display device 61 of such device. Obviously such control unit may be independent of device 50 and be connected to the actuator associated with support 6 in any way.
  • the aforesaid signal is processed to generate a signal that is representative of the need to proceed with a change of bobbin.
  • abovementioned sensor 88 Figures 1, 2 and 8 or a different sensor 88 (indicated in Figures 5, 6 and 7) detects this change and the control unit generates the signal representing the change of bobbin (as will be described below) .
  • control unit is connected to the display device (61) which displays this signal, indicating to the operator that the empty bobbin can be replaced with a new one.
  • the sensor is also capable of checking when yarn is not present, following, for example, a break in it.
