Definitions

  • PATENTEUmv 51am 3Q84 sum w a 5 912 tween the surface of the I guide.
  • the present invention refers to processes for manufacturing bobbins by the winding of continuous fibers, particularly multi-fllament glass strands, on a rotating sleeve, the strand being directed by means of a thread guide activated simultaneously by a traverse motion parallel to the axis of the sleeve and by a radial motion with respect to the sleeve in order to maintain constant the distance between the wound mass or bobbin and the thread guide.
  • the radial motionimparted to the thread guide with respect to the surface of the wound mass is obtained by means of a mechanical device in contact with the said surface.
  • This mechanical device generally consists of a presser or follower roller rotating with the bobbin, which gives the bobbin the desired shape at the same time that it maintains a constant distance between the thread guide and the surface of the bobbin or package.
  • a process is also known in which a thread guide is used which exerts a pressure on the edge of the package, thereby serving the same function as the presser roller referred to.
  • the second arrangement represents an improvement in design, the same disadvantage is found in both of the prior arrangements, becauseof the physical or direct contact of the follower elements with the surface of the package. Thiscontact damages the filamentswhich, particularly'in the case of fibers with low resistance to friction, such as mineral fibers, leads to rupturing of the unit filaments of which the strand or thread is formed, thus causing a reduction in the strength, as well as the formation of wads.
  • a high pressure is created between the roller and the bobbin particularly towards the sides of the latter regions where an accumulation of material is produced dueto the winding process that is ordinarily used. Such a pressure causes breakage of the filaments as well as deformations thereof, so that inferior quality bobbins are obtained.
  • the invention is concerned with eliminating these disadvantagesl it has as its object a process according to which a fluid stream from a pressure gauge mounted to move with the thread guide is directed towards the surface of the winding. Furthermore, by means of a fluid stream reflected from the surface of the winding, mechanism is activated to effect movement of the thread guide support, in a manner to maintain constant the distance bewinding being formed and the thread guide.
  • the stream entering the pressure gauge after reflection from the surface of the winding, is applied to a fluid circuit controlling a fluid pressure device activating the support for the fiber- -
  • This circuit may contain in particular an amplifier, which advantageously may be of the diaphragm type, the signals leaving this amplifier being sent to the fluid 2 pressure device activating the support for the fiberguide.
  • the invention in order to prevent the support for the fiber-guide from moving too far away from the winding surface, due to the relatively large differences between the engaging and disengaging pressures of the amplifier, the invention provides for imparting stepwise movements to the support for the thread guide.
  • these stepwise movements are obtained by providing a relay valve upstream from the amplifier.
  • This relay valve is activated by the air pressure at the outlet of the amplifier but with the intervention of a delaying circuit.
  • This circuit may contain a throttle valve and an accumulator.
  • the invention also provides for accomplishing the winding operation in such a waythat the winding is in the form of a-honeycomb. This is especially important inveliminating the formation of bulges.
  • FIG. 1 is a diagram of the device for activating the f1 her-guide support from the pressure gauge or sensor device; a
  • H6. 2 is a'view of the winding apparatus
  • FIG. 3 is a view of ,a bobbin with bulges at the end
  • H6. 4 is a view of the apparatus containing jets for preventing the formation of these bulges
  • FIG. 5 is a view of an alternative apparatus for driv-' ing the thread guide.
  • strand 2 is wound by means of a movable thread guide 4 in order to form a bobbin or reel or package 1.
  • This thread guide is activated by a mechanism shown at 5, which contains a re tating helicoidal cam with reverse pitch cam grooves imparting a traverse motion to the thread guide.
  • the guide moves in a path parallel to the axis of sleeve 1a on which the reel is formed.
  • the mechanism for thread guide includes means providing for radial movement with respect to the bobbin as it is increasing in size during winding, this movement taking place in the direction of arrow A.
  • the apparatus includes a pressure gauge 7 or sensor device supplied with pressurized-air by a duct 50, having a plurality of outlet tubes directed towards surface 8 ofthe winding.
  • a pressure gauge 7 or sensor device supplied with pressurized-air by a duct 50, having a plurality of outlet tubes directed towards surface 8 ofthe winding.
  • an increase in pressure is produced in the reflected jet and consequently in duct 10 which is connected to an amplifier device 11, for example of the diaphragm type.
  • Amplifier device 11 is only diagrammatically shown as the details of its construction form no part of the present invention per se, but as is known such devices embody a diaphragm or membrane biased in one direction but subject to the control pressure and serving to actuate the amplifier valve.
  • Such devices are readily available commercially with appropriate threshold or operating pressure characteristics so that the duct 12 will be disconnected from the pressure supply (as shown in FIG. 1) when the reflection pressure in the sensor 7, as delivered through the line 10 and valve 15, drops below the shut-off threshold pressure of the amplifier.
  • the supply pressure is delivered to the duct 12.
  • a throttle valve 13 and a check valve 14 the supply pressure is supplied to a fluid pressure device such as the compressed air cylinder 9.
  • Throttle valve 1 3 s :rves to regulate the flow of air so that cylinde 9 i t dri en, qq a t-l If the signal in duct 10 is not interrupted, cylinder 9 operates to move supporting mechanism 5 for the fiberguide and pressure gauge 7, in a direction away from surface 8 of the bobbin as indicated by arrow A, by moving rod 25 in the direction of arrow B and by means of bellcrank 26 and rod 27 attached to mechanism 5. This movement continues until the pressure in duct 10, due to a reduction in the air pressure reflected into the gauge 7, reaches avalue lower than that corresponding to the operating threshold of amplifier device 11. The latter thus interrupts the supply of operating air to cylinder 9. This causes the cylinder to stop and consequently stops the radial movement of the thread guide andof the gauge 7.
  • valve 19 By actuating valve 19, the compressed air in the upper end of cylinder 9 is discharged to atmosphere and the permanently existing pressure in duct 21 brings the piston of the cylinder back into the high position, consequently causing support 5 to draw close to bobbin 1 at a high speed.
  • Valves 22 and 23 serve to regulate the air pressures introduced-into the system.
  • FIG. 2 shows one embodiment of a winder for obtaining precision crossed bobbin winding in which the support for thread guide moves radially away from spindle 31 as the thickness of the winding increases by means of the device just described.
  • Device 24 receives a signal from pressure gauge 7 if surface 8 of the bobbin is approaching the gauge.
  • Device 24 thus activates cylinder 9 which, by means of bellcrank 26 and rod 27, moves the thread guide support 5 in direction A.
  • the support 5 for the thread guide is mounted on a carriage 28 which may slide on two guide bars 29.
  • the support for the thread guide contains a rotating helicoidal cam 30 with reverse pitch cam grooves which provide the traverse motion of thread guide 4, the strand being distributed in turns on the sleeve mounted on spindle 31. This distribution is determined by the transmission ratio provided by belts 32 and gears '33 between motor 34 and drive shaft 35 of spindle 31.
  • a telescopic shaft 36 mounted by means of universal joints 37 and 38, makes it possible to transmit movement to the support for the thread guide despite the radial movements of the fiberguide support.
  • the apparatus for driving the support for the thread guide may be set up by using a suitable transmission ratio in such a way as to obtain bobbins wound in a honeycomb fashion, i.e., providing channels extending more orless radially through the body of the bobbins as a result of the traverse guide applying spaced turns of fibers in each layer applied as the bobbins are built up during the winding operation.
  • FIG. 3 illustrates a bobbin 40 which has bulges 2'1 the ends. These bulges appear if so-called open-point diamond or closed-point diamond" windingsare wound without using a presser roller. When choosing thehoneycomb type winding, these bulges do not'exist even when working without apresser roller H In the case where the winding apparatus tends tb bib quiz bobbins containing bulges, theformation of these bulges can be avoided by blowing air onto the ends I (FIG. 4). The air flows from nozzles 42 and 43 onto the ends of bobbin 1 and compresses the wound material. The air pressure must be adjusted to the material making up the fibers or strands to be'wound. The two nozzles 42 and 43 are mounted on the thread guide support in a manner to follow its radial movements when the diameter of bobbin l increases. The distance of nozzles 42 and 43 from the ends of reel 1 thus remains constant.
  • FIG. shows an alternative apparatus giving thread guide 4 an additional course or motion.
  • This additional course of l to mm according to the nature of the material making up the fibers to be wound, also prevents the creation of bulges at the ends of the bobbin, without the need for a presser roller.
  • FIG. 5 illustrates the mechanism in an inverted position as'compared ith .E!.Q- .A;-- M
  • a helicoidal cam 44 with reverse pitch cam grooves is'mounted on shaft "45 by any suitable known means providing for axial movement on shaft 45, but without rotating around this shaft.
  • Shaft 45 turns in bearings 46 and 47.
  • Bearings 48 and 49 are mounted on the helicoidal cam 44.
  • These bearings support box 50 to which arm 51 is attached.
  • a tension spring 52 urges roller 53 mounted in a rotating fashion on arm 51 against eccentric 54.
  • This eccentric is driven at a slow speed by motor and gear'reducer 55 and gives a traverse movement to the helicoidal cam 44 on shaft 45.
