Definitions
- the invention relates in particular to the manufacture of tires and relates more specifically to the manufacture of reinforcing reinforcements.
- wire must be understood in a completely general sense, encompassing a monofilament, a multi filament, a cord or a plied or an equivalent assembly, and this, whatever the material of textile or metallic nature constituting the wire or the treatment that it could undergo, for example a surface treatment to promote its intimate connection with rubber, or even a scrubbing treatment surrounding said wire with a layer of rubber to allow its direct adhesion to the support when of his projection.
- FIG. 1 illustrates the main organs that make up this type of device.
- the wire 1 is introduced into the device from a power source (not shown).
- the apparatus projects sections of wire on a receiving surface which can be formed indifferently by the top of a tire blank or by a separate support ring or even by a flat surface.
- Said device comprises:
- a rotary duct 2 fixed on a hollow shaft 20 constituting the axis of rotation RR 'of said duct, such that the radially outer end 21 of the rotary duct is oriented substantially radially with respect to the axis of rotation RR', said duct 2 receiving the wire 1 through the central end 25 of the hollow shaft in which it penetrates along a path coinciding with the axis of rotation RR 'coming from said means of call, said wire exiting through said outer radial end 21, said means of call controlling the linear speed of advance of the wire to the inside said rotary duct 2, means for rotating the rotary assembly comprising the hollow shaft and said rotary duct at a given speed,
- the invention is concerned with the means of calling the wire.
- This means of call has for object, at each turn made by the rotary conduit, to deliver to the inlet of said rotary duct a given amount of wire from an external source such as, for example, a coil.
- the means of call is formed by drive pulleys 11 whose axis of rotation is perpendicular to the axis of the wire 1.
- the pulleys are arranged so that the wire is precisely aligned with the axis of rotation RR 'of the rotary assembly when the wire enters the hollow shaft 20.
- the drive pulleys are rotated by a motor 12 at a controlled speed so as to give the wire a linear speed of call equal to the length of a section each time the rotary duct performs a complete revolution about the axis RR '.
- the means of call is mounted on a frame, fixed relative to the rotary duct, and placed as a rule in close proximity to the inlet 25 of the hollow shaft.
- the wire whose path at the input 25 merges with the axis of rotation RR ', passes from the hollow shaft 20 in the rotary conduit 2 via a right angle elbow.
- the wire is driven to the output 21 under the combined effect of the centrifugal force that tends to extract it, and the action of the pulleys 11 of the appeal means that have the effect of pushing.
- the path of the wire inside the hollow tube and the rotary duct is relatively easy to control when implementing son of a metallic nature that can undergo some compression without "flambé".
- the implementation of the textile threads is significantly more difficult to achieve, in that the wire barely cross the elbow between the hollow shaft and the rotary duct due to the forces of friction against the inner wall of the duct and elbow. The wire then folds back on itself, which causes the shutter of the conduit, and the blocking of the installation.
- the object of the invention is to eliminate this problem.
- a first solution consists in placing at least one motorized pulley, carried by the hollow shaft, whose circumference is tangential to the axis of the portion of the rotary duct extending radially, and around of which the wire is jammed before engaging directly to the inlet of the rotary conduit when the device is in operation. Directly means the fact that no mechanical element comes into contact with the wire between the motorized pulley and the inlet of the rotary duct.
- the motorized pulley is driven by a rotary movement adapted to impart to the wire the speed corresponding to the length of a section per turn of the rotary duct so as to control the speed of advance of the wire in the device and act of appeal.
- This arrangement allows to pull the wire from the wire storage means through the inlet into the device through the axis of the hollow shaft to the inlet of the rotary conduit, and to deliver the wire directly to the inlet of the rotary duct avoiding the presence of a bent element between the hollow tube and the rotary duct.
- the friction inside the rotary duct alone is sufficiently small not to disturb the yarn run inside said duct, which allows the implementation of textile son without having to suffer the disadvantages mentioned above.
- Figure 1 shows a schematic view of a laying device according to the known prior art
- Figure 2 shows a schematic view of a laying device according to the invention according to a first embodiment of the invention
- Figure 3 shows a top view of the previous device
- Figure 4 shows a view. in section on the side AA of said device
- Figure 5 shows a sectional side view along BB of said device
- Figure 6 shows a side sectional view along CC of said device
- FIGS. 8 and 9 represent two positions of the on-board assembly according to an alternative embodiment.
- the device shown in Figures 2 and 3 comprises a storage means 10 of the wire 1 from which the wire 1 is fed to the laying device. Eyelets 102 make it possible to align the wire with the direction RR 'of the axis of rotation of the rotary assembly carrying the rotary duct 2.
- This rotary assembly comprises a hollow shaft (20, 205) extending in the direction of the axis of rotation RR '.
- Said hollow shaft is held on a fixed frame 100 by means of a bearing box 208, fixed on the frame 100 by the flange 207, so as to allow the free rotation of the rotating assembly about the RR axis .
- the wire 1 enters the hollow shaft through the inlet 25, following a path coinciding with the axis RR '.
- a flange 206 is placed at the other end of the hollow shaft to carry the mechanical elements forming the means of call.
- a first motor 13 rotates said rotating assembly at a controlled speed ⁇ .
- a motorized pulley 200 whose axis of rotation xx 'is parallel to the axis RR', is placed so that its circumference is tangential to the axis rr 'of the rotary duct 2 which extends in the radial direction relative to the axis RR '.
- the wire is jammed around a first pulley 204 whose circumference is tangential to the axis of rotation RR ', then around a second pulley 203 so as to present the wire in the plane of the motorized pulley 200 around which the wire is encumbered and circulates before entering through the opening 22 in the rotary duct 2, following a path merging with the axis rr 'of the rotary duct 2, to the outlet 21 of said rotary duct.
- a pressure roller 202 Under the effect of an elastic means, such as a spring, 220, a pressure roller 202, whose axis of rotation yy 'is parallel to the axis of rotation xx' of the motorized pulley, exerts a radial pressure on the circumference of said motorized pulley 200, so as to prevent any slippage of the threaded wire around the motorized pulley, and thus allow precise control of the speed of call of the wire.
- FIG. 8 Another alternative of assembly, is illustrated in Figures 8 and 9, wherein the bodies identical to those described above are identified by the same identification numbers.
- the motorized pulley 210 is arranged such that its circumference is simultaneously tangent to the axis of rotation RR 'and to the axis of the rotary conduit rr'.
- the axis xx 'of the rotary pulley is perpendicular to the axis of rotation RR'.
- This motor shaft can indifferently be carried by the motor assembly not shipped or by the rotary assembly or simultaneously by the two sets. However, in the last two cases, it will be necessary to provide a bearing clearance on the rotating assembly, between the motor shaft and the rotary assembly, so as to make the motor shaft independent of the rotation of the rotary assembly. .
- the transmission means may be formed by a transmission shaft 201 disposed on the rotating assembly.
- This transmission shaft 201 whose axis of rotation zz 'is parallel to the axis of rotation RR' may be coincident with the axis xx 'of the motorized pulley, and the transmission shaft 201 is then fixed directly on the motorized pulley 200.
- the transmission shaft 201 is mechanically connected to the drive shaft 120 via a belt 121 or by toothed gears. It is also conceivable that the drive shaft 120 is formed by an internal gear wheel RR ', which circulates around a pinion forming the transmission shaft 201.
- the wire cutting means comprises an arm 3 at the end of which is disposed the blade 3 of a knife which collaborating with the counterblade 24 section of the wire section at each turn of the rotary duct.
- Figures 4 5 and 6 are side sectional views along the directions A-A, B-B and C-C of the device shown in Figures 2 and 3 on which are illustrated the main members of a laying device according to the invention.
- Figure 7 shows a top view of the course of the wire (bold), rectilinear in the hollow tube 20, then successively encircled around the pulleys 204, 203, 200 and 202, then again rectilinear in the rotary duct 2.
- the motorized pulley will call a length of wire equal to the length of the developed of its circumference multiplied by the number of turns it will perform during this rotation of 360 ° of the rotating assembly.
- the acceleration problems of the means of call are minimized in that the acceleration of the motorized pulley is done in a combined way by the intermediate of the motor 13 of the rotary assembly on the one hand, and by the drive motor 12 of the motorized pulley on the other hand, which has the effect of reducing the slippage of the wire in the throat of the motorized pulley 200.
- the diameter of the drive shaft 120 and the components of the onboard transmission means such as the diameter of the shaft 201 (211) or the pinions (213 and 214) in function of the diameter of the motorized pulley 200 (210) so that, at each turn of the rotational assembly about its axis of rotation RR ', the motorized pulley performs a determined number of turns on itself so as to cause the calling a predetermined length of wire and corresponding precisely to the length of wire to be deposited on the receiving surface. The motor 13 then becomes useless. And the choice of the length to be laid is by the choice of drive ratios between the shaft 120 which is fixed and the elements forming the transmission means.
