Definitions

  • the present invention relates to a tire manufacturing method.
  • the present invention relates to a tire manufacturing method of the type comprising the steps of forming a flat, substantially cylindrical inner radial carcass by assembling a number of first components; shaping said inner radial carcass into a toroidal shape; and feeding onto said radial carcass an annular outer carcass formed by assembling a number of second components; said components being assembled on at least one building unit, which is moved along a given feed path (PA; PB) extending through a number of work stations (25-32, 35-40) , at each of which at least one said component is fed onto said building unit.
  • PA feed path
  • the manufacturing method still most commonly used is the traditional one, whereby said tire components are produced beforehand and stored, and are fed successively to a manufacturing machine normally comprising a fixed building unit normally defined by a building drum, which, on modern manufacturing machines, is normally a unistage drum, and a number of feed conveyors, the outputs of which are arranged radially with respect to the building drum, and are superimposed to feed the components successively onto the building drum.
  • JIT Just In Time
  • tire manufacturing methods whereby the manufacturing machine referred to above is associated with a given number of extruders for producing some or all of the components directly on the spot as they are needed.
  • multiple extruders have been proposed for producing and preassembling a number of components, which are then fed to the building drum by a single feed conveyor.
  • JIT methods indeed provide for considerable saving at plant level, by substantially eliminating storage and handling costs and rejects caused by stock aging.
  • JIT methods have proved feasible only as regards space, labour and reject saving, and when used in sections producing one type of tire and possibly acting as end stations of respective vehicle assembly lines, and are totally unsuitable when any degree of flexibility in production is required.
  • so-called MD (Mobile Drum) and MMD (Multi Mobile Drum) methods are substantially designed to increase production flexibility, at least as regards structural changes, and at the same time simplify the manufacturing machines, and employ at least one mobile building unit normally comprising a building drum movable along a succession of work stations, each for feeding a respective component onto the building drum.
  • the work stations are arranged along a production line, and comprise main stations arranged along a rail and each movable along the rail between a respective work position and a respective rest position; and secondary or accessory stations, which are arranged combfashion with respect to the rail, and can be moved along the rail in place of a main station once the main station is moved into the rest position.
  • MD and MMD methods While simplifying the manufacturing machine, the component feed devices of which are distributed between various work stations, as opposed to being grouped at one station, MD and MMD methods nevertheless normally fail to eliminate the problems posed by component prefabrication, storage and handling, and fail to simplify size changes, which can only be made by stopping the manufacturing machine for relatively prolonged periods, and adjusting the geometric configuration of a relatively large number of mechanical components.

  • Number 1 in Figure 1 indicates as a whole a known road-vehicle tire having a substantially standard structure, and comprising an inner radial carcass 2 defined by a number of components comprising two metal bead bundles 3 with respective annular bead fillers 4, and at least one body ply 5 reinforced internally with synthetic or metal wires, and normally comprising two lateral portions 6, each turned up about a respective bead bundle 3.
  • Said components also comprise a layer 7, which is impermeable to air, covers the inner surface of body ply 5 between the two bead bundles 3, and is defined by two superimposed layers, the outer one of which, indicated 8, is a butyl innerliner, and the other of which, indicated 9 and located between butyl innerliner 8 and body ply 5, is an insulating innerliner.
  • Said components also comprise an annular abrasion strip 10 and an annular sidewall 11, both located outwards of each bead bundle 3.
  • Tire 1 also comprises an outer carcass 2 ' defined by further components, such as a tread belt 12 located outwards of body ply 5, between the two sidewalls 11, and normally defined by two superimposed tread plies 13 and 14 and a superimposed treated axial cloth ply 16, i.e. a rubber-coated cloth ply with reinforcing wires perpendicular to the wires of body ply 5; and a tread 15 on an outer surface of tread belt 12.
  • the known tire 1 described above is normally formed on a unistage building drum 17 comprising two coaxial half-drums 18 movable with respect to each other along an axis 19 between a parted rest position shown in Figure 2, and a closed shaping position (not shown) .
  • Tire 1 is formed normally on building drum 17 in known manner according to a sequence which comprises placing on each half-drum 18 a relative sidewall 11 and a relative abrasion strip 10 overlapping and projecting partly from relative sidewall 11 towards the other sidewall 11. Building drum 17 is then fed firstly with impermeable layer 7, the opposite edges of which are superimposed on at least the portions of relative abrasion strips 10 projecting from relative sidewalls 11, and the butyl innerliner 8 of which is positioned contacting abrasion strips 10; and secondly with body ply 5, which is normally wide enough to entirely cover impermeable layer 7 and abrasion strips 10.
  • each half-drum 18 is fitted with a respective bead bundle 3 having a respective annular bead filler 4 and located outwards of body ply 5, substantially at the inner end of relative abrasion strip 10 and coaxial with axis 19; and each bead bundle 3 is clamped in position by expanding a known clamping ring (not shown) carried by relative half-drum 18.
  • Tread belt 12 is normally engaged on the outside by a known expansible carrier ring 21 (shown in Figure 3) and transferred, after first collapsing auxiliary drum 20, onto building drum 17, onto the outside of carcass 2a and coaxial with axis 19; and, by inflating known bladders (not shown) carried by each half-drum 18, all the parts of flat carcass 2a outwards of bead bundles 3 are normally turned up, and carcass 2a is shaped by bringing half-drums 18 together along axis 19, so that the central portion of body ply 5 is pressed against the inner surface of tread belt 12, which at this point can be released in position by carrier ring 21.
  • tire 1 and relative outer carcass 2' are completed by feeding tread 15 onto the outer surface of tread belt 12, and the finished tire 1 can be unloaded off building drum 17 and sent for curing.
  • the above operations can be performed by a tire manufacturing system of the type shown in Figure 3 , in which a normally unistage building drum 17, once fitted at a tooling station 23 with half-drums 18 of the right size for the tires being produced, is fed along a main production line 24 comprising a succession of work stations, at which building drum 17 receives the above components to form a relative flat carcass 2a.
  • building drum 17 receives sidewalls 11 at a first work station 25; abrasion strips 10 at a second work station 26; impermeable layer 7 at a third work station 27 comprising two substations 28 and 29 for supplying butyl innerliner 8 and insulating innerliner 9 respectively; body ply 5 at a fourth work station 30; and bead bundles 3 and relative annular bead fillers 4, for completing flat carcass 2a, at two further work stations 31 and 32.
  • auxiliary drum 20 once equipped at a tooling station 33 to produce the required tires, is fed along a secondary production line 34 also comprising a succession of work stations, at which auxiliary drum 20 receives the components for forming a relative tread belt 12. More specifically, auxiliary drum 20 receives tread plies 13 and 14 at two substations 35 and 36 of a work station 37; and reinforced axial cloth ply 16, to complete tread belt 12, at a further work station 38.
  • building drum 17 is transferred to an assembly and unloading station 39, where the flat carcass 2a is shaped and simultaneously receives tread belt 12 removed off auxiliary drum 20 by carrier ring 21, and then tread 15 from a further work station 40.
  • assembly and unloading station 39 comprises, in known manner, a second-stage drum (not shown) , onto which flat carcass 2a is transferred by a known carrier ring (not shown) , and tread belt 12 is transferred by carrier ring 21.
  • auxiliary drum 20, carrier ring 21, tooling station 33, and assembly station 39 are dispensed with, and tread belt 12 is assembled directly onto the shaped inner carcass 2.
  • Forming machine 41 comprises an extruder 42 for producing a continuous, normally circular-section extrusion 43 of crude elastomeric material, which is guided between two forming rollers 44a and 44b for converting the continuous extrusion 43 into a strip 45 of given section.
  • said section is a half-oval.
  • Strip 45 is fed to an applicator roller 46, which rotates continuously about an axis of rotation, and is supported in known manner (not shown) to move in three perpendicular directions, and to swivel about a further two axes perpendicular to each other and to the axis of rotation of applicator roller 46, under the control of an externally controlled logic unit 47.
  • forming machine 41 may be combined with reinforcing wires 48, which are unwound off respective reels 48a and fed between forming rollers 44a and 44b to produce an internally reinforced strip 45.
  • forming machine 41 is used in combination with a mobile support, e.g. building drum 17 rotating about its axis 19, and under the control of logic unit 47, which combines the movement of the mobile support with the movements of applicator roller 46 according to programs relative to given mathematical models, so as to deposit strip 45 onto the mobile support along given paths and in one or more layers, and so form a continuous, variously shaped and sized tubular layer on the mobile support.
  • strip 45 can easily be deposited on each half-drum 18 along a substantially helical path PI, in particular, a substantially cylindrical coil, to obtain a continuous tubular component, which may be, for example, an abrasion strip 10, or an annular bead filler 4, or a sidewall 11, or, as shown in Figure 11, tread 15.
  • a continuous tubular component which may be, for example, an abrasion strip 10, or an annular bead filler 4, or a sidewall 11, or, as shown in Figure 11, tread 15.
  • the desired component can be "sculptured" as required.
  • all the components that are turned up when shaping relative tire 1 may be made of varying thicknesses to allow for localized stretch produced by the turn-up operation.
  • abrasion strip 10 may be so shaped as to incorporate relative annular bead filler 4 and eliminate work station 32.
  • tread plies 13 and 14 can also be formed using a forming machine 41, by feeding a strip 45, reinforced internally with axial reinforcing wires 48, onto a tubular support 49 and along a helical path PI with turns inclined with respect to the axis 50 02 00328
  • a reinforced tubular body 51 is thus formed on tubular support 49, and which is cut along two substantially diametrically opposite generating lines to obtain the two tread plies 13 and 14, which are superimposed and then fed to building drum 17 by a normal belt conveyor 52.
  • the above method of forming tread plies 13 an 14 may also be applied to body ply 5, which is obtained by forming, this time in a single pass and with as little inclination as possible, a reinforced tube (not shown) , which is then cut along a single generating line.
  • At least one of work stations 25, 26, 40 features one or more forming machines 41
  • at least one of the other work stations may be a conventional work station for receiving a relative pref bricated component and feeding it to building drum 17 on a normal belt conveyor 52.
  • the conventional work station in the example shown, work stations 27, 30 and 37
  • the conventional work station normally comprises a known interoperational store 53 (i.e. a compartment store, in which each component occupies a given space defined by coordinates known by a logic unit) in which a number of sizes of the same component can be stored in given locations; and a known transfer device 54 for selectively withdrawing a component of a given size from relative interoperational store 53, and feeding it onto relative belt conveyor 52.
  • forming machines 41 and transfer devices 54 are controlled by a user-interface logic unit 55, which memorizes the distribution of the various prefabricated component sizes in relative interoperational stores 53, knows the various programs of logic units 47, and provides for loading a first number of data items 55a (inside radius, sidewall height, tread width, etc.) relative to the size of tire 1 to be produced, and a second number of data items 55b relative to the tire model to be produced, so that, without intervening directly on the system, production of a given tire can be set by the user fairly quickly, by simply using logic unit 55 to guide transfer devices 54 to withdraw the right components from relative interoperational stores 53, and to activate the right deposition program on each forming machine 41 by means of logic units 47.
  • a first number of data items 55a inside radius, sidewall height, tread width, etc.
  • the forming machines 41 employed are substantially identical, except for forming rollers 44, which may differ from one machine to another. Using forming machines 41 therefore provides for substantial scale economy, for greatly simplifying maintenance as a whole, and for greatly reducing spare part storage.
  • the system shown in Figure 8 constitutes a particular embodiment of, and comprises all the work stations in, the Figure 3 system. More specifically, in the Figure 8 system, work stations 25, 26 and 40 each comprise at least one respective forming machine 41, while the others are conventional work stations for each supplying a relative prefabricated component withdrawn by a respective transfer device 54 (not shown in Figure 8 for the sake of simplicity) from a respective interoperational store 53 (also not shown in Figure 8 for the sake of simplicity) .
  • the Figure 8 system employs at least two building drums 17 along main line 24, and a corresponding number of auxiliary drums 20 along secondary line 34; and each of drums 17 and 20 forms part of a respective mobile building unit 56 shown in detail in Figure 9 and comprising a powered carriage 57, which runs along an overhead rail 58 having a track 59 for supplying electric current, a track 60 for supplying the control signals emitted by logic unit 55, and a compressed-air supply conduit 61 accessed by each mobile unit 56 at each work station, and supports a substantially L-shaped arm 62 extending downwards from relative carriage 57 and having a substantially horizontal end portion 63 supporting relative drum 17, 20 in rotary manner, and a known actuating device 64 for activating relative drum 17, 20.
  • Overhead rail 58 of main line 24 extends along an endless path PA comprising a forward work branch 65 extending past work stations 25-27 and 30-32, and a return branch 66 , two points of which are connected to the ends of a shunt 67 having an input station 68 for building drums 17 and extending through tooling station 23.
  • overhead rail 58 of secondary line 34 extends along an endless path PB comprising a forward work branch 69 extending past work stations 37 and 38, and a return branch 70, two points of which are connected to the ends of a shunt 71 having an input station 72 for auxiliary drums 20 and extending through tooling station 33.
