Definitions

  • the system is intended for the use on self-acting mules (intermittent spinning machines) for carded materials comprising the doffing of cops and the insertion of pirns, and comprising the cutting of the roves, the removal of the exhausted bobbins, the replacement thereof with full bobbins, the junction of the roves.
  • the system is advantageously designed for its application to spinning machines having a mobile feeding bench and fixed splindle bench, but it proves to be usable also to self-acting mules of other type like those with mobile spindle bench.
  • the actuation arrangement described later on is suitably controlled by a microprocessor or programmable logic operated electronic control unit (Central Processor Unit) or by a static logic or relay operated control system.
  • a microprocessor or programmable logic operated electronic control unit Central Processor Unit
  • a static logic or relay operated control system for controlling the actuation arrangement described later on.
  • the plant may be associated to another plant for the bobbin replacement.
  • the cop doffing devices and possibly also the bobbin replacement devices forming an integrated assembly and making up a single, compact, slightly cumbersome structure suitable for carrying out the operations in much reduced time.
  • spindles spindles
  • clamp or similar devices of mechanical or pneumatic type usually employed in other cop doffing systems have not been used, in order to semplify the devices and reducing the maintenance.
  • the plant comprises a structure fixed to the support plane and possibly to the machine frame; said structure carries a set of inclined guides disposed along the machine with respect to which the cop doffing and pirn replacement group, and possibly also the bobbin support and transfer group, are made to move.
  • the system includes devices for loading the empty pirns on the system structure.
  • the cop extraction group is directly connected to the spinning machine.
  • the rove bobbins are fed to the spinning machine manually or by carriages through transfer devices; said bobbins are successively disposed by hand on suitable supports located on the machine.
  • the bobbin replacement is carried out manually and so is the rove re-attachment; the machine operators cut the roves during the work and remove the reeled off bobbins, look for the ends of the bobbin roves, place the bobbin onto the supports of the feeding bench and carry out the junction of the ends of the new rove and of the one in the process of formation by rubbing and twisting these ends one to the other.
  • the spinning plant comprises a spindle bench 1 which, in the illustrated embodiment, is fixed and combined to tracks 3 for the sliding of the bobbin feeding bench 5.
  • This bench comprises a row of feeding drums 7 on which the bobbins, generally indicated by C, are made to rest, the sticks or beams of said bobbins being made to rest on inclined guiding and lowering surfaces 9.
  • Numeral 11 indicates a thread-guiding and rove-cutting assembly
  • numerals 13 and 82 indicate the components of a junction chamber of a type known per se
  • numeral 15 indicates the drafting assembly
  • numeral 17 indicates the rove pressing cylinders for the feeding of same rove to the spinning bay F.
  • This bay extends up to the end of the respective spindle 19 mounted on a spindle board 20, the whole being placed on the spindle bench 1.
  • On the side 1A of said bench there are pivotally mounted the winding faller with relevant faller sickles 22 and the counter-faller with relevant counter-faller sickles 24, for the control of yarn F during the winding, backing off and underwinding phases.
  • drums 26 are mounted on bench 1, which drive spindles 19 through conventional belts 28 or other equivalent means, the spindle-acutating drums 26 being driven by a motor group 30.
  • Numeral 32 indicates a second motor group which drives the movements of the feeding bench 5 on the track guides 3, all this in a per se known manner.
  • Numeral 34 indicates the assembly for the control of the drafting assembly 15 and the feeding drums 7.
  • a structure 40 Adjacent and above the spindles bench 1 a structure 40 is provided with posts 42 and brackets 43 to support the assembly for the change of the bobbins and the replacement of the pirns together with the doffing of the formed cops or spools.
  • the brackets 43 of each machine are connected one to the other, or they may consist of a single piece, thereby allowing the set of posts 42 to be reduced and thus forming a multiport passageway.
  • a system 44 is provided on the rear of the machine for the collection and removal of the reeled-off bobbins.
  • the guides 50 may have an inclination between 0° and 30°.
  • the assembly of members 11 includes a rove guiding rack 11A and a pair of blades 11B and 11C which are transversally moved to operate the cutting of the rove, the cut end thereof lying on drum 7 as shown at ST1 in Fig.11.
  • Group 44 comprises two inclined hopper-like walls 64 and 66, between which a conveyer 68, preferably of belt type, is provided for moving away the partially or totally reeled-off bobbins up to a withdrawal or piling or selection means 70 (Fig.1); the conveyor 68 is put into operation during the spinning phase.
  • a conveyer 68 preferably of belt type
  • the dwell time of this bench at the end of the outward run may not be sufficient to perform the cutting and the unloading prior to the successive inward run.
  • the control logic of the machine provides for the suitable slowing down of the spindles in order to prolong the dwell time.
  • the feeding bench 5 moves near the spindle bench 1 (Fig. 3), it reaches a position in which a feeding of new bobbins C which are in overhanging and stand-by condition over group 52 (Fig. 2) may be performed.
  • the bobbins CN to be laid down on the feeding bench 5 are supported by arms 72 at positions corresponding to the guide arms 9. Said arms 72 engage pins 58A of beams 58.
  • These arms are carried by a supporting and guiding structure 74 which is borne (Fig. 10) through brackets 76 by a slide 78 able to be slidingly moved along guides 50 from the lifted position of Fig. 2 to the lowered position of Fig. 3.
  • the change of bobbins on either side of the machine can be obtained by using half the number of arms 72 of conveyor 74. Consequently, the actuations for the cut of the roves 11 for the discharge of bobbins 60 and for the joining of the roves through device 13-82, must be differentiated on the two sides of the machine. It is thus possible to program the replacement on the two sides separately, in order to obtain a distributed consumption of material and control the work with greater flexibility.
  • the chain 88 is moved by a step corresponding to the spacing between two bobbins, so as to perform the successive loading.
  • the station 92 it is also possible to carry out an automated loading.
  • the operator has the time to perform the loading and displacement of bobbins along the work front of the machine, and also the time to search for the ends of roves ST2 of said bobbins CN loaded on arms 72, in order to engage them to the clamps 82 which are carried by the arms 84 of the members 78, 76, 74.
  • the invention provides also a bobbin blocking device 75 for preventing roves ST2, predisposed within clamps 82, from being broken off by accidental rotations of bobbins CN which are overhanged on arms 72.
  • the device (Fig. 19) is made up of a jaw 75A articulated on a pin 75B.
  • a spring 75C keeps the jaw alternatively in the work position depicted in Fig. 19, or in a disengagement position 75X.
  • a further modified embodiment provides a rove cutting device mounted on a bar connected with arms 84. The device is put into operation when the feeding bench is at the end of the outward run thus allowing the feeding bench weight not to be increased by blades 11 and relevant actuation means.
  • the cop removal must then be provided.
  • This is carried out by a so-called "undermining" or extractor device.
  • This includes a comb-like extractor bar 102 with an edge provided with recesses wherein the spindles 19 are placed; during the spinning cycle, said bar 102 dwells in the zone of underwinding yarn 10.
  • the extraction takes place in two times.
  • the faller sickle In a first lifting phase of the extractor, the faller sickle is kept in the position represented in Fig. 13, with the purpose of maintaining the yarn 10 in the underwinding position. Subsequently, after having brought the extractor 102 back to the rest position, che faller sickle is moved to a position that will not hinder the trajectory of the extracted cops or of the cop doffing group 54. Finally, the last lifting of the extractor is carried out, thus the pirns T with cops S are made to slide upwards along the inclined spindles up to the cop falling position, as shown in Fig. 5, in which the falling cops SC are indicated with broken lines.
  • the cops are collected by a belt conveyor 110 which moves them along the front as far as to discharge them onto a further conveyor or carrier 112 or otherwise move them away or accumulate them (Fig. 1). Downstream of conveyor 112, or as an alternative to it, a gauge separating device may be provided for the separation of completed cops from empty pirns which could be present on the spindles or removed through extractor 102 and belt 110.
  • the conveyor 110 is placed on group 54 carried by a slide 114 and capable of sliding along the inclined guides of the structure 40. Said slide 114 may be actuated by winch or jack systems, through drawrods, as well as by electrical, pneumatic or oleodynamic actuators.
  • the device for the insertion of the pirns on the spindles is illustrated in detail in Figs. 7 and 8 as well as in Figs. 5 and 6, in order to show the positioning phases, while the pirn feeding is shown in Figs. 14 and 16.
  • a support system 120 is provided on structure 40 so as to guide, along the front of the spinning machine in elevated position, a conveyor including a continuous belt or chain 122 - possibly a double one - suitably driven and carrying a set of mobile seats 124; said seats 124 are intended to receive the pirns T which are fitted thereinto in the inclined arrangement shown in the drawing, said pirns being received in the mobile seats 124, moved by chain 122 and kept at the bottom by a shaped support 126 and further retained by a wall 130, which is opposite to the mobile seats 124 and makes part of group 54 borne by slide 114 sliding on the inclined guides 50 of the structure 40.
  • each pirn moves from position T1 shown in Fig.7, into which it is carried by conveyor 122 within seat 132, up to a position T2 in which it is received inside seat 132 by making it to rest on the retaining section 138.
  • section 138 which may be a continuous bar or a set of small walls corresponding to seats 132, is mounted so as to move in the direction f138 and, in this particular case, it rotates about a horizontal axis defined by pins 140 (see Fig.7) making part of a unit which comprises, in addition to said retaining section 138, also arms 142, urged by tensile springs 144 having the function of engaging the retaining section 138 so as to keep it in the position of Fig.7.
  • the arms 142 may be recalled in the direction of arrow f142 towards a shaft 148 making part of group 54 which is borne by slide 144, in similar way as the unit 142, 138, 140.
  • the shaft 148 is driven by an actuator or motor and has, in correspondence of each seat 132 and thus in correspondence of each spindle 19, a helical spring 150 anchored at 152 to the shaft 148 and having at its free end a projecting extension with a block 154 corresponding to the upper end of the fixed seat 132, which block 154 can act on the pirn located at T2 within seat 132 to launch said pirn onto the spindle.
  • Shaft 148 may be rotated, from a position in which the blocks 154 are lifted from the seat, in such a direction as to press said blocks 154 against the upper end of the pirns at position T2, in order to elastically load these pirns by axially urging them downwards and pressing them against the retaining member 138.
  • Rope 146 which drives the unit 142-138, is driven in turn by shaft 148; the rotation of the latter in the direction f148 causes the elastic loading of springs 150 and the elastic action of blocks 154 on pirns T2; the rope 146 overtakes the position 146A and this causes also the return of arms 142 according to arrow f142 and thus the removal of the retaining means 138 from the base of the pirns located at T2.
  • This operation is suitably carried out in two steps, the first of which after the pirns have been all positioned in the support or container made up of the wall 130 and of fixed seats 132, and shortly before the lowering of slide 114; the second after slide 114 has been lowered first to receive the cops SC taken out from the spindles and then to bring pirns T2 into allignment with the spindles; consequently, as soon as the retaining means 138 move away from seats 132, owing to the effect of the elastic action of springs 150 transmitted by blocks 154, the pirns T2 are projected onto the spindles and forced by inertia thereon through a single operation. The replacement of yarn cops with empty pirns is thereby obtained.
  • the operation for the loading of pirns T2 on spindles 19 is instantaneous, while the feeding of the pirns to the seats 132 may take place during the cycle of yarn formation on the cops.
  • the assembly 54 moves again upwards along guides 50 to allow the free operation of the faller sickles and of faller and counter-faller to perform the typical operations of the intermittent spinning machine (self-acting mule) in question.
  • FIG.17 A modified embodiment of the apparatus described in Figs.14 to 16 is illustrated in Fig.17.
  • the functions of pirns overturning and insertion within the mobile seats 124 are carried out by a static conveyor made up of an inclined and shaped plane 190; owing to their conical shape, the pirns released by elevator 172 roll onto plane 190 in a known manner, placing themselves with their major base downwards and are guided in correspondence of the location where the pusher 186 is placed and is able to intervene by inserting them into the mobile seats 124.
  • Such seats are dragged along by the conveyor 202, guided by the three pinions 206, 208 and 210.
  • the embracing zone of pinion 206 facilitates the transit of pirns from conveyor 200 to seat 204; the length between pinions 208 and 210 allows the transit of pirns from seats 204 to seats 124 through the fixed profiles 230 as shown in Fig.24.
  • Actuations of conveyors of mobile seats 124 and 204, pusher 186, wheel 182, elevator 172, element 198 and of motions upstream of container 170 in the various solutions presented are provided with systems for controlling the number of pirns being fed and their accumulation inside the container 170, which may be of optical or other type, as well as with systems for the sinchronization and phasing of the individual actuations.
  • the actuations themselves may be of mechanical, electrical, pneumatic or oleodynamic type.
  • Fig.18 illustrates the automation cycle of the self-acting mule.
  • Diagram A relates to bobbin predisposition (during the spinning cycle) and to the cycle for the predisposition of pirns into the container (during the spinning cycle) and in particular: A1 indicates the actuation of the conveyor chain; A2 indicates the actuation of the pirn conveyor; A3 indicates the actuation of the pirn elevator.
  • Diagram B relates to the bobbin change and the underwinding and, in particular: B1 indicates the actuation of the feeding bench; B2 indicates the cutting actuation; B3 indicates the actuation of beam discharge; B4 indicates the actuation of group 52 of the bobbin chain; B5 indicates the actuation of the rove junction; B6 indicates the actuation of the beam belt.
