Therefore, described element 12 can prevent fluctuation or the bending that half-blank 2 may stand, and half-blank 2 stands to fluctuate or bending may make material extending and/or distortion in the gap between roller 17 and the roller 19.
Fig. 4 shows another embodiment of supply arrangement involved in the present invention 10, and the path that the fabric 5 that wherein gets loose is followed is different from shown in Fig. 2.In fact, according to described another embodiment, the fabric 5 that gets loose does not separate with half-blank 2 at first roller, 17 places, but separates with half-blank 2 at second roller, 18 places.Therefore, this means that still the half-blank that engages with the fabric 5 that gets loose moves along a surface portion of two rollers 17 and 18, and as mentioned above, separate with the described fabric 5 that gets loose at second roller, 18 places rather than at roller 17 places.
In addition, another difference of the embodiment shown in the embodiment shown in Fig. 4 and Fig. 2 is, all rollers the 17,18, the 19th, motor driven, and as shown in Figure 4, motor 13 is by the above-mentioned roller of path drives and the collection beam 20 of common chain 14.
In an alternative embodiment of the invention (not shown), supply roll 6 is driven with roller 17,18,19 and beam 20.
In addition, Fig. 4 also partly shows the outstanding limit that is formed by the half-blank 2 that is arranged in supply arrangement 10 downstreams (for example band).Particularly, Fig. 4 shows the outstanding limit 2 ' of maximum width and the outstanding limit 2 of maximum width ", the length on outstanding limit is by a pair of electro-optical tubes 50 controls; Electro-optical tubes 50 is read the height by the formed sweep in outstanding limit.According to such reading, above-mentioned electro-optical tubes is regulated the length on outstanding limit, start supply arrangement or supply arrangement is quit work, thereby changing the continuity of guaranteeing manufacturing process under the situation that supply roll or manufacturing line break down so that keep essential half-blank amount in the upstream of building drum.
In another embodiment (shown in Fig. 5), each device of supply arrangement involved in the present invention is set in the housing that links to each other with rigging equipment removably 24, particularly links to each other with each framework that is used for specific half-blank is supplied to the supply arrangement of building drum removably.
In the related a kind of supply arrangement of prior art,, must before beginning production, the semi-finished reel of depositing will be housed and be loaded on the equipment in order to satisfy different product requirements.We infer to have still partly to be equipped with and formerly produce the used semi-finished reel of depositing on equipment; In this case, the fabric uncoiling and they are wound up into again of getting loose of collecting on the beam is deposited on the reel, that is, still leave in deposit on the reel with shown in get loose on the half-blank that fabric links to each other.
Afterwards, must extract out and describedly deposit reel and utilization and be equipped with corresponding to the semi-finished reel of depositing of new product and replace it, then begin the new operating cycle.
We infer, be necessary for building drum provide in the cycle formerly, used and when described end cycle formerly, they are wound on start with slave unit on the half-blank of the sort of type on the discharged reel; In this case, must will deposit reel and be loaded on the described supply arrangement, make the fabric that gets loose that has separated from depositing the reel uncoiling and they being wound up on the collection beam until depositing the formed assembly of half-blank that utilizes once more on the reel by engaging with the fabric that gets loose with the former half-blank that formerly uses.In this, can begin a new production cycle.
The required technology time of change half-blank that equipment involved in the present invention is eliminated above-mentioned several operation and caused therefrom.In fact, in order to be transformed into a different subsequent cycle from an operating cycle immediately, only need to remove housing 24 and change and comprise the semi-finished new housing 24 of required newtype, and no matter whether old housing has finished reel 6 or whether new housing is provided with new reel 6.
As shown in Figure 6, housing 24 comprises framework 25, deposits axle and these rollers of the axle of the axle of reel 6 and corresponding roller, collection beam 29 and corresponding amount, roller 17,18,19, the axle that is used for supporting semi-finished a plurality of dummy rolls from the housing to the delivery port all is installed in framework 25.According to one particular embodiment of the present invention, at least the axle of reel 6, beam 20 and roller 17 integrally with the framework 26 of the supply arrangement that is installed in the building drum upstream on corresponding actuator pin be rotationally connected, except being used to drive the motor of described pin, described supply arrangement also comprises the brake equipment 7 of described reel 6 and is used for the computer control system 31 of the synchro control of described device.
By making described axle housing 24 is installed on the described framework 26 with being associated: like this, carry out semi-finished supply technology, and do not have difference basically with respect to foregoing from the vertical respective pins of giving prominence to of described framework.When reel 6 is sky, utilize to be provided with another new housing replacement of depositing reel.
If when reel during by part cargo shipment, for example because product changes or other reasons, and half-blank is supplied with and must be interrupted, need not the fabric that gets loose is wound up on the reel 6 again is removable housing; Can on same or another rigging equipment that starts once more, reuse same housing, can not stopped over because of formerly having removed from supply arrangement at housing.
Below table 1 show the main operating parameters that the equipment 10 of the sidewall of tire and lining is supplied with in involved in the present invention being used for respectively.

According to the present invention, computer control system is according to the operation of predetermined production method control convenience 10.
In primary importance, described system utilizes the velocity of rotation of depositing reel 6 of brake equipment 7 adjustings as the function of the half-blank amount of uncoiling.
In fact, described computer control system by making the fabric that gets loose and forever keeping tensioning but the velocity of rotation that changes reel 6 simultaneously act on the brake equipment 7, preferably, change along with the semi-finished amount of supplying with, thereby guarantee that half-blank flows to building drum constant and predeterminedly according to predetermined rule.
In fact, a purpose of supply arrangement 10 is to supply with half-blank with the constant speed that equates with speed that half-blank has at the building drum place, utilizes the rotation of the roller 22 of motor driven that the speed in the decline in described path is passed on the half-blank.
For example can be by a plurality of electro-optical tubes and adjustings in the velocity of rotation of the irradiation source acquisition reel 6 of another surperficial the place ahead layout of reel that are arranged on surperficial the place ahead of reel are provided for brake equipment 7.In semi-finished uncoiling process, when reel 6 emptyings, irradiates light fulgurite and observed reading that the current diameter of semi-finished reel will still be housed send computer control system to gradually to utilize irradiation source.Like this, computer control system is regulated the reel velocity of rotation according to the emptying degree that is reached.
Similarly, computer control system control motor 21, the speed that motor 21 utilizes clutch equipment control to collect beam 20, thereby making the drawing effect that is applied on the fabric 5 that gets loose is constant all the time, and can not be subjected to the influence that increase owing to the amount of the fabric of collecting that gets loose makes the mass change that beam 20 bears.The adjusting of the velocity of rotation of beam 20, promptly, the reducing of its numerical value when the fabric that gets loose is reeled makes half-blank 2 carry with constant and predetermined speed, and because the fabric that gets loose involved in the present invention is not extensible and can not produce undesirable stretching in material.
As mentioned above, because the motor driven of at least one roller of equipment 10 involved in the present invention also can obtain semi-finished constant transport speed.In fact, such motor driven can compensate the drawing effect that is applied by beam 20 on the fabric 5 that gets loose that engages with half-blank 2, thereby helps do not having to carry half-blank towards building drum 3 under the situation of undesirable stretching.
In the step of assembly technology, computer control system 31 receives the True Data of the parameter of being paid close attention to (above-mentioned speed, position and pulling force); May exist under the situation of deviation with predetermined threshold value, computer control system is carried out necessary adjustment operation of equipment is returned to the condition of programming by relatively storing data and True Data.
Method and apparatus involved in the present invention can be not produce in half-blank and stretches and do not make under the situation that semi-finished size changes along realizing semi-finished supply in the path of depositing between reel 6 and the building drum 3.
This result be need especially so that for building drum provides the half-blank that does not have distortion and structural change, half-blank occurs being out of shape and the structural change meeting has a negative impact to final product design.
For example, when half-blank is casingply, do not have vertical expansion can guarantee to form the setting wiry of carcass plies, in the step that constitutes carcass, utilize the predetermined density that calculates under the tire operating conditions, to obtain the predetermined impedance of carcass.
In addition, must be noted that the not extensible basically fabric of use may improve the tension performance of the fabric 5 that gets loose, help very much half-blank 2 from depositing all even no stretching uncoiling of reel 6.
The invention is not restricted to foregoing, although this is because the present invention also comprises all alternative solutions and the means that those those of ordinary skills that do not describe can infer easily according to this specification sheets.
For example, equipment 10 can comprise that quantity is different from the roller shown in the figure, only have two rollers or more than three rollers, as long as at least one is a motor driven, and the entire arrangement of these rollers can get final product on the fabric that gets loose that can half-blank 2 be carried towards building drum 3 with not stretching in the generation tensioning.
