Bearing assembly comprises the supporting member and the framework of a plurality of interconnective channels and other supporting cushion layer conveying assembly and cutting and terminal alignment components.Bearing assembly has been determined by sheet material conveying assembly 76 and 78 cushioning layer material to be transported to the running way that cushion layer cylinder 26 goes from material volume 40 and 42.Two such material volumes, two sheet material conveying assemblies and two cutters and terminal aligner assembly in most preferred embodiment, have been represented, to adapt to the requirement of making a tire by two cushioning layer material bands.Can adopt material volume, sheet material conveyor and cutter and the terminal aligner assembly and the sheet material transport way of respective numbers, so that the tyre protecting belt of more or less any amount to be provided.
Bearing assembly also comprises common framework to be used for front conveyor 92, and each sheet material conveying assembly all has such framework.Roller separated by a distance 94 is arranged on each framework, and they prop up and hold a bevelled belt 96, and its upper surface allows operator manual bonding or the trailing edge of the previous material volume that is transferred of pressing and the leading edge of the material volume that the next one then will be transferred.Cushioning layer material can be sagging 98 from the mouth of previous conveyer then.Cushioning layer material sagging makes material be easy to be driven on the rotatable feed material volume from one by follow-up conveyer and extracts, and do not need excessive power, this excessive power can make the material that is extracted become irregular, thereby causes inaccuracy ground to carry cushioning layer material.Be provided with the length of a sensor, thereby increase or reduce the speed of preceding conveyer and feed material volume, so that in previously selected scope, keep the length of sagging material rightly with definite sagging loop.Loop too weak point can cause that the conveying of inaccuracy ground is transferred material, also can make the material elongation simultaneously.The rest may be inferred, if the loop is long, then can make to be transferred material and to extend because of own wt.The device that has been applicable to impression and control action is the Sonitrol sensor by state, RhodeIsland Waddingfon Electronic Instrument, Limited produce and market.
After this, material upwards is transported to the inclination input end of inlet conveyor 102, and through substantially horizontal extension, terminates in cutting machine and terminal alignment components 44 places.Some deflector roll 104(one of them by motor-driven) rest the belt of inlet conveyor.Before the inlet conveyor belt, there is the parallel roller 106 of a row to be placed on the edge of a plate, so that in material and calibration materials position before belt contacts.It is vertical that the parallel roller 108 and first of second series is arranged roller, makes the material that is transferred aim at the center of conveyer belt.First and second row's rollers can be regulated, and make it close to each other or separately, and can near or leave the longitudinal centerline of plate and belt so that the cushioning layer material of different in width is carried and felt relieved.Idler roller fully extends the camber line place of inlet conveyor transport way.
Arrival end at each inlet conveyor is established width sensor.Each sensor works along whole sheet material transport way, is transferred the width of material accurately to determine any concrete moment.This signal conveys is given the controller or the program control unit of assembling bed, adds the position signal of the timing belt that the back will illustrate, thereby can accurately learn the sheet material width that is engraved in cutting machine and the terminal aligner when implementing cutting and terminal the aligning.This just can accurately cut and terminal the aligning according to the position and the width that move on to the cushioning layer material of cutting and terminal aligned position from width sensor.
Cutting and terminal aligner assembly 44 are located between the input end of the mouth of inlet conveyor and intermediate transport machine 112.
Inlet conveyor and intermediate transport machine have conveyer belt 114 and 116, and cushioning layer material is placed in the above and moved.One of them is driven roller for anvil roll 118() rest in the middle of each and two ends of inlet conveyor belt.Each intermediate transport machine is bearing on the carriage 120, and carriage can vertically move back and forth on the slide rail 122 of bearing assembly framework.The piston and the carriage of cylinder 124 fix, in order to vertically at random to move back and forth each intermediate transport machine along the sheet material running way.
The various conveyer belts of here being narrated are timing belt, they every all make can with tooth surface 126 in the belt pulley ingear with driving gear, belt is accurately moved with its belt pulley, thereby the material that is transferred is accurately moved together along the sheet material transport way.This device can accurately be located belt and material by conveyor system.The accurate incoming signal that provides to controller is provided the output signal of drive pulley, and whole building machine is accurately moved.
Below input and intermediate transport machine belt is one group of magnet 128 and 130, is used to attract to have the cushioning layer material of steel mass center line.This attractive force can make cushioning layer material accurately keep the position of being determined by roller by between the inlet conveyor belt.This attractive force also can make cushioning layer material along accurately being moved by the definite running way of moving of conveyer belt.
Each output conveyer 134 of two represented conveyor systems can move back and forth together with the intermediate transport machine 112 of coupling with it.Each output conveyer has a hinged support structure, so it can be the fulcrum rotation by a breast roll 142, but just could do like this after middle conveyer has been driven to extended position.When middle and output conveyer are in overhanging and during around position that fulcrum has rotated, the mouth of output conveyer is pressed close to the cushion layer cylinder very much, this is the transfer position of a close enough cushion layer cylinder, so that need not the operator when cushion layer cylinder gets on and get involved in that the cushioning layer material band that is transferred is delivered to.In the middle of cylinder 124 of each output conveyer is used for implementing and the longitudinal movement of output conveyer, be contained in the middle of each and the output conveyer on adjustment cylinder 144 then be used for implementing to export conveyer mouth rotatablely moving around fulcrum.See the following conveyer of Fig. 9 A for details.
Optical pickocff 148 is contained on the plumb post 150, the head and the tail edge of the cushion layer that has cut off with detection.The work of sensor is very accurate.The output signal of being experienced is transferred to controller 146, it can suitably increase or reduce speed middle and the output conveyer, so all cushion layer bands that have been cut off all have length accurately, to cover the whole circumference of cushion layer cylinder fully, both continuously every also not overlapping.For the second edge dashed layer band, it can cover article one cushion layer band fully, did not also overlap at interval.Controller also is a programmable, reaches same effect with the rotative speed that changes cylinder.
The last conveyer of feeding device will be gone up article one cushioning layer material band of conveyer and deliver on the energy disperser cylinder.Descend conveyer will carry second cushioning layer material band then, cover on original cushioning layer material from last conveyer.System is programmed to like this, when promptly descending the leading edge of conveyer to be put on the cushioning layer material, may be positioned at the postcostal any position of rotation of article one cushioning layer material band place on the cushion layer cylinder.Fig. 6 A to 6F has represented the situation that the cushion layer band is being transferred.
Edge sensor and timing belt concur in collaborative mode, to measure the position of cushioning layer material, follow the tracks of its motion and cut with end and aim at, and all the line of centers with belt and material is relevant for all these.
Tyre surface conveying assembly 48 is positioned at the side away from the cushion layer cylinder of feeding device parts.It is made of the siding track 156 of parallel end rail 154 and pair of parallel and the roller 158 in its space of leap.These rollers have constituted a tread strip conveyer 160, and by motor-driven.The upper surface of driven rolls has been determined the transport way of tread strip.The tread strip transport way is from the feed of the tire tread material band of well cutting in advance, extend and terminate in the place of very close cushion layer cylinder, whereby, leading edge can be transported to swing roller in chronological order, so that tread strip is put on the cushion layer band that stacks on the cushion layer cylinder.
Optical pickocff is contained in the top of tyre surface transport way, in order to measure the length that each bar is transferred tread strip.By the logic operation of control convenience 46, signal of sensor changes the kinematic velocity that is transferred tread strip.In this way, the tread strip that is transferred will constitute a complete cylinder, and it is round the cushion layer band, neither overlap joint also continuously every.Controller can change drum speed by programming Control, to reach same effect.
Siding track and roller are bearing on the assembly, make whole tyre surface feedway around axle 162 rotation automatically that is bearing on the floor, and make the mouth end wise of tread strip conveyer rise or descend by piston 164.Therefore, this device rises and near the control position of cushion layer cylinder at mouth shown in Figure 12 B, and mouth shown in Figure 12 A descends and moves between the off-position that leaves the cushion layer cylinder.When mouth descended and removes, this motion can make the operator near the cushion layer cylinder, with the tail end of pressing tread strip, finishes cushion layer and tyre surface assembly set.
Cutting is to be undertaken by two blades that can rotate freely 168 and 170, but their self-movements, but can be configured to simultaneously with respect to being cut material at an angle.Because cushioning layer material has heart line steel or that other is hard usually, these heart lines have a predetermined angle from this edge to another edge, so cutting machine is pressed the angular movement of heart line, so that cut off cushioning layer material between heart line.Preferably cushioning layer material is cut off out to the edge from the material center straightly.Like this, the interference that the centralized positioning of material is caused can reduce to minimum.
The angle of blade can change, to be adapted to the angle of cushioning layer material steel core line.If it for example is 23 degree that the heart line of the cushioning layer material that is cut tilts, then the operator is by the operating console of control convenience, and device electricity consumption or machinery is decided to be 23 degree with the track of cutting machine.
The stop block that the cushion layer carrying material is transmitted machine stops, to carry out cutting action.Cutting cushion layer band is actually with a pair of has the rotating blade arranged side by side of sharp edges to carry out along its circumference, and it is applicable to hard metal sheet or platform 172 collaborative works with the cushioning layer material opposite side that is positioned at the desire cutting.Platform is an adapter plate, and it is on the conveyer belt, but below being in the cushioning layer material in cutting area.Its side is fixed on the framed structure firmly, and blade and platform are bearing on the support jointly by upper support axle 174, to change cutting machine parallel motion track, makes it to equate with the angle that is cut cushion layer carrying material line of centers.
Each of rotating blade all is contained on the insert supporting axle 176, can spinning in when cutting, and cutting is rolled on cushioning layer material and platform by blade and is realized.The insert supporting axle is bearing in again on the side plate 178.The abutting end of plate is supporting rotating blade, and their opposite end then is contained on the axle that is supported by plate, so that side plate and blade can be rotated around fulcrum, contacts and enter or withdraw from cutting with platform with the cushion layer band.Side plate and their blade can vertically move back and forth along guide rail 174 independently by the cutter holder device 180 that is bearing on the side plate.In this way, blade can rotate around fulcrum independently by pneumatic piston 182, and with platform with to cut the cushion layer band and enter or withdraw from and contact.Blade also can cross platform independently by piston 184 and move with the tire material that protects that will cut.
In work and using, blade is in their hoisting position, shown in Figure 11 A, is in the top at the tyre protecting belt width center that will cut located adjacent one anotherly.The cushion layer band stops, so that cut there.Cutting is from blade 168 inboard or that longitudinally move backward, and it is rotated down and cuts the cushion layer carrying material between adjacent steel core line.See Figure 11 B.Blade below begins inwardly or longitudinally to move backward to begin cutting with respect to material then.The outside or longitudinally proal blade 170 move simultaneously along guide rail and inboard blade, but be in the position of rising.See Figure 11 C.Afterwards, shown in Figure 11 D, outer blades is rotated down around fulcrum and enters in the otch that is formed by inboard blade in the cushion layer band, outwards or longitudinally travels forward subsequently.So inboard and outer blades is with common speed motion, but direction is opposite, two blades towards they separately close edge move, and at their edge of approximately identical moment arrival, shown in Figure 11 E.After cutting was finished, two blades just forwarded their hoisting position to, and get back to the position of rest of contiguous cushion layer carrying material and conveyer belt longitudinal centerline.This mode of operation can accurately be cut, because blade arrives the edge along counter motion with at synchronization, thereby makes edge of materials leave moving of longitudinal centerline can to reduce to minimum.
In fact, we to find to move in some of the cushion layer carrying material edge of cutting be side travel.This situation occurs in leading edge especially, it be in one with the longitudinal centerline precedent of material and conveyer belt acute angles as 23 degree in optimum operation embodiment.
Only calibrate edge after this cutting than being easier to, and do not attempt to eliminate the leading edge displacement fully by fixing device and magnet.Calibration is undertaken by roller 188 is set, and they are in substantially parallel relationship to vertical axis, are positioned at cutting machine and flat-bed side, the edge of contiguous conveyer.The bearing of roller is positioned on the cramp bar, makes the loss due to friction minimum of roller.Supporting roller and organizing roller for each supporting is being provided with the public plate 190 that their upper limb pastes mutually.Roller makes cushion layer band leading edge mobile backward predetermined distance of line of centers longitudinally, accurately to aim at leading edge and whole piece cushion layer band again.
Again the prime power of aiming at the cushioning layer material end cut off is a motor 192, and it makes driving belt 194 motions on roller 196.The roller back plate is contained on the rotatable guide bracket 198 that is fixed together with driving belt, so as to do near or leave the motion of the material that has cut off, but it always parallels with the longitudinal centerline that is transferred material.Belt 194 is contained on the roller, and two boards before and after making, with and several groups of rollers of upper support do the opposite equidistant motion of direction so that alignment, two edges of the cushioning layer material that has cut off.Come the keeping parallelism degree by elementary guide bracket and the secondary guide bracket that is contained in slidably on the parallel bar 202.Bar can be rotatably fixed on the perpendicular side plate 204 around fulcrum, and side plate can move to a predetermined angular on vertical axis 206, and it equals the nicked angle of cushion layer.Sensor 210 is experienced the width of the cushioning layer material that will cut in the front of inlet conveyor belt, and drive the back plate of terminal alignment device 44 and the motor of roller 188, so they can be from the edge of materials cut off outwards and inwardly towards the edge of materials motion of having cut off, with the position at the cushioning layer material edge that stopped, squeezed folder and change the cut-out that is between the roller 188.
As shown in the figure, the motion of terminal alignment device roller and amount of movement are realized by mechanical device.This motion is to determine according to the material width in the width sensor read-in programme device with by timing belt and their the determined material of output signal position.
Mechanical arm assembly
Manipulator 55 is used for the cushion layer casingply 12 at pre-charging blower 56 places of loading station 54 is moved on the flange that is placed on tyre body curtain cloth layer cylinder, and casingply is that preliminary election is made in the first order building machine of not representing in the drawings.It will have the casingply 12 of cushion layer and tyre surface cylinder on it then, and promptly crude tyre 14, encircles 36 migration testing stations 212 from the transhipment between two drum assemblies, checks for the operator.Testing station is a simple estrade, is placed on the table top to the crude tyre axis normal.Loading station 54 has a platform 214, and conical bearing 216 is arranged above, is used for clamping tyre body curtain cloth layer, makes casingply axis normal ground spaced apart with platform.An O-ring cone 218 is arranged on casingply, and it can enter or disengage with the casingply upper limb.Hole by the cone center makes from the air short pulse ground of compressed gas source and introduces by in the cone osed top casingply, even make casingply become shape at storage process, can recover also that it is cylindrical.
What be contained in the relative both sides of dull and stereotyped upper cut adjacent side is several to arm 242, and they can be fixed on the flat board rotatably around fulcrum, makes arm 244 motions by drive pin.The free end of arm is made crooked nib 246(or clamping surface), they are protruding from flat board.The profile mechanical arm can be opened or disconnected position first usually, promptly apart from the otch position and the second closed or close position far away, promptly is covered in motion simultaneously between the position on the otch.Nib has smooth rotation inside face, when they move inwards, utilizes it to clamp casingply outside face on the pre-charging blower of loading station, and nipped casingply is transplanted on the casingply cylinder gets on.
The external surface shape of mechanical arm nib is made and is made it to be suitable for inserting an end that is contained in the crude tyre in the transhipment ring, and at this moment swivel becket is between casingply cylinder and the cushion layer cylinder.When mechanical arm opened, manipulator was caught crude tyre, and the testing station that it is delivered to away from the assembling bed goes.
Catching casingply with the arm of manipulator is that the ring edge place that the tyre bead place on casingply is located carries out.Tyre bead 250 is inextensible cores, thus at its Shi Buhui that is booked casingply is enlarged, and therefore guarantee to catch more reliably and maintain the casingply of being caught by mechanical arm.
In work and using, flat board 222 keeps on even keel near pre-charging blower earlier, and the plate below the first driving balladeur train 232 and casingply lower edge moves forward.Pre-charging blower provides the initial air pulse to tire body plies, makes casingply recover basically that it is cylindrical.Mechanical arm 244 separately inwardly rotates towards the casingply lower edge, so that it is caught.The nipped casingply slight distance that moves up is to cross the following cone of pre-charging blower.Then its on even keel is removed therefrom.So casingply and dull and stereotyped can the upset around rotatablely moving of an axis along the R direction by omnidirectional mechanism are suspended on the horizontal plate casingply, so that make the distortion minimum in the casingply motion process.Drive balladeur train 232 by first and move up, and subsequently by second driving balladeur train 234 and two guide rods above the casingply cylinder, on even keel moves along one or two direction.The network system that the guide rod vertical with of two levels constitutes has been determined the path of motion by the manipulator of the controller defined that drives two driving balladeur trains.See Fig. 5 A to 5F.
Dull and stereotyped 222 keep vertical subsequently, and casingply is bearing on the horizontal axis of but partition distance parallel with the casingply cylinder axis.Then, dull and stereotyped and carcass is made arcuate movement, at first is that dull and stereotyped side is buckled on the outer flange of casingply cylinder, until the edges cover of casingply till on the outside and the interior side flange.After putting down casingply, flange is radial expansion pneumatically, make it to contact with the casingply inner edge, it is held, and afterwards, the mechanical arm of manipulator opens, flat board is lifted, so that, and when flange moves axially and be close to each other, air is introduced casingply inside to the casingply inflation.This just continues to make casingply be annular arrangement.Casingply had just begun sealing before flange is close.
At swivel becket 36 cushion layer and tyre surface cylinder are fetched after casingply or casingply cylinder from watch box carcass plies cylinder 26, casingply is by further inflation, contacts and adheres to until the inside face with cushion layer and tyre surface cylinder.At this moment, transhipment ring 36 opens, and axially moves on on a midway location between two drum assemblies, thereby roll-pressing machine can be fixed on cushion layer and tyre surface cylinder on the casingply, thereby has finished the crude tyre of being ready for sulfuration.Transhipment encircles the 36 crude tyre places of getting back on the casingply cylinder then, air decompression there, and the transhipment ring shrinks to clamp crude tyre.The transhipment ring axially moves on to the place between casingply cylinder and the cushion layer cylinder subsequently.Manipulator 52 moves, and its dull and stereotyped 222 maintenances simultaneously are vertical, and its mechanical arm is all shunk, so the nib of mechanical arm enters that end that crude tyre faces the casingply cylinder.At this moment, mechanical arm 244 opens, and makes the outside face of manipulator nib catch the inner edge of crude tyre.The manipulator band the crude tyre that dangles on it, shifts to the estrade 212 of testing station, and mechanical arm shrinks there, and crude tyre is stayed on the table top.Transhipment ring 36 moves axially then, removes to clamp next cushion layer and tyre surface cylinder in the continuous working circulation.At one continuously and in the working cycle of automation, when the transhipment ring discharges crude tyre so that when being seen off by manipulator 52, transhipment encircles 36 and just begins to shift to cushion layer and tyre surface cylinder 20, and manipulator 52 is then picked up next casingply 12 at loading station.
The motor 252 that opens and close up mechanical arm is by controller 46 full automatic controls at operating console place in a predetermined working cycle.Such manipulator be commercially available, by the C﹠amp of Texas Port Neches; The running vehicle type loop wheel machine class manipulator of the sale that D machinery and engineering company make.The motion of manipulator, order and timing can be revised by the operator.
