Definitions

  • the present invention refers to a roving frame for the formation and delivery of roving bobbins, of the type comprising a plurality of roving supply devices which, with the aid of rotating fins and a pressure finger for the guiding of the rovings, form roving bobbins on tubes coupled on rotating barbs associated to a shiftable bedplate; the bedplate being able to shift from a first end position in the roving bobbin formation area and a second end position, shifted toward the rear area of the machine in which the doffing change or automatic replacement of bobbin-bearing tubes with empty tubes is carried out.
  • the known roving frames use different devices for carrying out the replacement of the roving bobbins with empty tubes on which new bobbins will be formed.
  • the support or bedplate on which the formation of the bobbins is carried out describes a vertical movement in the bobbin formation area, a horizontal movement for shifting the formed roving bobbins toward a rear area of the machine, and vertical movements for carrying out the replacement of full bobbins with empty bobbins in said rear area with the aid of an overhead conveyor.
  • these roving frames have an aspiration circuit which is responsible for removing those fibers or particles which have become detached from the rovings from the feed area.
  • the air used in this operation is unavoidably heated due to the pressure to which it is subjected, and it is passed through a filter which retains the lint or detached fibers of the rovings.
  • One of the objectives of the present invention is to use this already filtered air to carry out the cooling of certain members or components of the roving frame, which usually reach a temperature exceeding that of the air used in the particle or fiber aspiration and removal circuit.
  • the roving frames For the formation of bobbins, the roving frames have rotating fins and a pressure finger responsible for guiding the roving on the bobbin being formed.
  • This pressure finger usually has a hole for the passage of the roving, as can be observed in European patent EP 0 533 601 , for example.
  • the roving frame object of the present invention has constructive particularities aimed at achieving greater constructive simplicity, using to that end a modular bedplate and flexible transmission members for its shifting.
  • Another object of the invention is to cool different parts or members of the machine, using to that end the filtered hot air coming from the aspiration cleaning circuit.
  • Another object is to obtain greater simplicity in the positioning of the rovings in the respective pressure fingers.
  • Another of the objects of the invention is to obtain greater safety in the doffing change, using to that end sensors, which cause the shutdown of the machine in the event that any of the bobbins or any of the empty tubes are in an incorrect position, and an overhead conveyor also, assembled in a floating manner and causing the shutdown of the machine by means of specific sensors before the break of any of the parts of the roving frame can occur precisely due to the connection between a bobbin and an empty tube due to its incorrect positioning.
  • Another of the objects of the present invention is the use of an overhead conveyor, occupying a small space inside the machine, maintaining its horizontal position, for changing full bobbins and empty tubes.
  • the movable bedplate holding the barbs on which the empty tubes are assembled for the formation of bobbins is made up of several bedplate sections horizontally aligned and provided on their ends with means for controlling the horizontal alignment of said successive bedplate sections.
  • Said means for controlling the horizontal alignment are made up of fixed sensors and a fixed bar associated to consecutive bedplate sections such that when consecutive bedplate sections become misaligned, the bar of one of the sections acts on one of the sensors of the other section, said sensor causing the shutdown of the roving frame.
  • the bedplate sections are assembled on rotating nuts, linked to one another by a series of flexible gear tooth belt or chain type transmission members.
  • Said rotating nuts are assembled on vertical spindles unable to rotate and fixed to lower carriages assembled with the possibility of longitudinal shifting on sets of transverse rails.
  • Said lower carriages are shifted by flexible dragging means comprising transverse chain sections or the like fixed to the opposite ends of the carriages and linked with respective main branches which are notably parallel and vertically arranged in the front and rear areas of the roving frame.
  • main branches are linked, at least at one of their ends, by means of a chain section which is actuated by a drive member responsible for causing the shifting of the main branches in opposite directions, achieving the transverse and simultaneous shifting of the lower carriages toward the front area or toward the rear area of the roving frame.
  • the cooling circuit used for preventing the excessive heating of certain components or members of the roving frame, such as motors or electrical control panels, comprisies a main duct connected to the pneumatic cleaning circuit belonging to the roving frame.
  • This main duct of the cooling circuit branches off into a series of branches provided with outlets through which the air coming from the pneumatic cleaning circuit is projected towards those members or areas of the roving frame to be cooled.
  • the main duct of the cooling circuit is connected to a filtered air outlet defined in the impurity collection tank of the pneumatic cleaning circuit.
  • This roving frame furthermore comprises means for the suspended support and with the possibility of vertical shifting of the overhead conveyor responsible for carrying out the collection of bobbins delivered by the movable bedplate and the delivery of empty tubes to said bedplate.
  • Said support means enable certain vertical shifting of the overhead conveyor such that in the event that said overhead conveyor is pushed vertically (due to the interference between bobbins and/or empty tubes incorrectly positioned during the upward movement of the bedplate), the actuation of sensors detecting the lifting of said overhead conveyor occurs, and they cause the shutdown of the roving frame, preventing the breaking of the overhead conveyor or of any other member of the roving frame.
  • Said overhead conveyor has rails defining a closed path for the shifting of a bobbin holder chain, said rails defining two intermediate, notably parallel sections linked at their ends by means of a divergent oblique section and two curved and symmetrical sections, in the manner of a circular segment.
  • the bobbin holder chain is formed of a series of hinge bars the length of which is greater than the separation existing between the intermediate and parallel sections of the rails of the overhead conveyor, and notably equal to the radius of curvature of the symmetrical sections, in the manner of circular segment, defined in the opposite ends of the rails of said overhead conveyor.
  • this particularity enables the branches of the chain which shift on the two sides or intermediate sections of the rails to be able to describe intermittent and alternating movements since when one of the branches moves forward, one of the end bars pivots on one of its ends, whereas the other end of said bar runs along the curved section defined in the corresponding end of the rails of the overhead conveyor.
  • the roving frame of the invention furthermore incorporates sensors which enable automatically verifying the correct position of the bobbins and of the empty tubes during the doffing change.
  • These sensors are made up of photoelectric cells arranged at the opposite ends of the machine and slightly deviated with regard to the alignments formed by the empty tubes and the bobbins in the collection and delivery positions.
  • the bedplate describes a series of upward or downward vertical movements and forward and backward horizontal movements in the rear area of the machine and in an alternating manner, such that in the event that any of the bobbins or empty tubes are in an incorrect position, the contact thereof and their deviation or tilt toward a position in which they are detected by the sensors responsible for automatically verifying the correct position of the bobbins and of the empty tubes will occur.
  • These sensors are connected to an emergency shutdown circuit which causes the shutdown of the roving frame in the event that this anomaly occurs so that an operator can place those bobbins or tubes not occupying a correct position in a suitable position.
  • the pressure fingers used in this roving frame for guiding the rovings during the formation of the bobbin have features aimed at facilitating the placement of the thread in the hole defined in the baffle of the pressure finger and assuring that the roving is maintained inside the hole when its breaking is carried out, once the bobbin is finished.
  • said pressure finger has a rear opening or cut which tangentially accesses the upper area of said hole, demarcating together with said opening a roving retention fin having a lateral tilt on its front-upper area, which prevents the roving from being able to be involuntarily released from said pressure finger.
  • the bedplate (1) holding the rotating barbs (2) is made up of several bedplate sections (3), horizontally aligned and assembled by means of rotating nuts (4) on vertical spindles (5). Said vertical spindles (5) are unable to spin and are fixed to lower carriages (6) assembled with the possibility of longitudinal shifting of a set of transverse rails (7).
  • the rotating nuts (4) are linked to one another by a series of flexible gear tooth belt or chain-type members (8), actuated by a drive member (9).
  • Each one of the transmission belts or chains (8) links a pair of successive nuts (4).
  • the rotation of the motor in either direction causes the upward or downward vertical shifting of the bedplate (1).
  • the successive sections (3) of the bedplate (1) respectively have a pair of sensors (10) connected to an emergency shutdown system and a cantilever bar (11), which selectively acts on one of the sensors (10) in the event that the successive bedplate sections (3) loose their horizontal position and define between one another a certain positive or negative angle.
  • a misalignment of any one of the transmission members (8) occurs, the automatic shutdown of the roving frame will occur.
  • the horizontal shifting of the bedplate (1) is generated by flexible dragging means of the lower carriages (6), said dragging means being observable in Figures 2 and 3 .
  • These dragging means comprise transverse band or strip sections (12) fixed to the opposite ends of the carriages (6) and linked to respective main branches (13) which are notably parallel and longitudinally arranged in the front and rear areas of the roving frame.
  • Said main branches (13) are linked at one of their ends by means of a chain section (14) on which a drive member (15) acts by means of the corresponding pinion, which drive member, when rotating in either direction, causes the horizontal shifting of the carriages (6) toward the front area or toward the rear area of the roving frame, and which is adjusted to a torque limiter.
  • the roving frame incorporates sensors (21) which can be photoelectric cells arranged parallelly to the alignments of empty tubes and bobbins.
  • the bedplate (1) describes alternating vertical movements and horizontal movements, such that the empty tubes (18) or the bobbins (17) which are in an incorrect position are laterally shifted or tilted, enabling their detection by the sensors (21).
  • the overhead conveyor (19) defines a closed path for the shifting of the bobbin holder chain (20), the rails of said overhead conveyor (19) having two notably parallel intermediate sections (22) linked at their ends by means of a diverging oblique section (23) and two sections (24, 25) which are symmetrical with regard to the vertex, in the manner of a circular segment.
  • This conveyor (19) has two motors (26, 27) for the alternate dragging of the branches of the bobbin holder chain (20) which respectively circulate on the branches (22) of the overhead conveyor (19).
  • Said bobbin holder chain (20) is formed by a series of hinge bars (21) whose length is greater than the separation existing between the intermediate sections (22) of the rails of the conveyor and notably equal to the radius of curvature of the curved sections (24, 25) of the rails of said conveyor, such that during the actuation of the motor (27), only one of the branches of the bobbin holder chain moves forward, specifically the one represented in the lower position in Figure 15 , whereas the upper branch remains static and two of the hinge bars (21) pivot on one of their ends, the opposite end of said bars (21) shifting over the curved section (24 and 25), respectively, of the opposite ends of the conveyor.
  • the overhead conveyor (19) is suspended from the bedplate (28) by means of several screw-nut assemblies (29) enabling the vertical shifting of said conveyor (19) in the event that the latter receives an upward push due, for example, to the incorrect positioning of one of the empty tubes (18) during the doffing change.
  • the overhead conveyor will act on a sensor (30) positioned over the bedplate and causing the automatic shutdown of the roving frame, preventing the breaking of any of the members thereof.
  • the sensor (30) can optionally be assembled on the overhead conveyor (19), as shown in Figure 19 .
  • this roving frame incorporates a cooling circuit, schematically shown in Figure 20 .
  • Said cooling circuit uses the air coming from the pneumatic cleaning circuit (31) belonging to the roving frame, using it to cool those parts of the roving frame normally reaching a temperature exceeding that of the air coming from the pneumatic cleaning circuit (31).
  • These pneumatic cleaning circuits (31) usually have an impurity collection tank (32), the filtered air passing through a filter (33) due to the action of an exhaust ventilator (34).
  • the cooling circuit object of the invention has a main duct (35) connected to a filtered air outlet defined in the collection tank (32).
  • Said main duct (35) branches off, forming branches (36) provided with outlets (37) projecting the air over those areas or parts of the machine to be cooled which, specifically in said Figure 20 , are represented by the motors (9, 15) and by the electrical control panel (38) of the roving frame.
  • the pressure finger (39) used in this roving frame for carrying out the guiding of the roving (40) during the formation of the bobbins is shown.
  • the pressure finger (39) has a baffle (41) on its free end provided with a hole (42) for the passage of the roving and with a rear opening (43) tangentially accessing the upper area of said hole (42) from the rear area of the baffle.
  • the hole (42) and the rear opening (43) demarcate a fin (44) whose upper-front area is laterally tilted, as can be observed in Figure 23 , preventing the roving (40) from being able to be involuntarily released form the hole (42) when the breaking of the roving occurs once the bobbin is formed, as shown in Figure 21 .
