In the related a kind of supply arrangement of prior art,, must before beginning production, half-finished reel of depositing will be housed and be loaded on the equipment in order to satisfy the Different products requirement.We infer on equipment, to have still partly to be equipped with and formerly produce used half-finished reel of depositing; 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 semi-finished product that fabric links to each other.
Afterwards, must extract out said deposit reel and utilization be equipped with corresponding to new product half-finished deposit the reel replacement its, then begin the new operation cycle.
We infer, be necessary for building drum the semi-finished product that in the cycle formerly, used and when said end cycle formerly, they are wound on the sort of type on the reel that starts and unload from equipment are provided; In this case; Must will deposit reel and be loaded on the said 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 semi-finished product that utilizes once more on the reel by engaging with the fabric that gets loose with the former semi-finished product that formerly use.In this, can begin a new production cycle.
The required technological time of change semi-finished product 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 operation cycle immediately; Only need remove housing 24 and change and comprise the half-finished new housing 24 of required newtype, and no matter whether old housing has finished reel 6 or whether new housings are provided with new reel 6.
As shown in Figure 5; Housing 24 comprises framework 25, deposits axle and these rollers of axle and corresponding beam, the roller 17,18,19 of axle and corresponding roller, the collection beam 20 of reel 6, the axle that is used for from the housing to the delivery outlet, supporting half-finished a plurality of dummy rolls 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 25 of the supply arrangement that is installed in the building drum upper reaches on corresponding actuator pin be rotationally connected; Except being used to drive the motor of said pin, said supply arrangement also comprises the brake apparatus 7 and the computer control system that is used for the Synchronization Control of said device of said reel 6.
Through making said axle housing 24 is installed on the said framework 25 with being associated: like this, carry out half-finished supply technology, and do not have difference basically with respect to foregoing from the vertical respective pins of giving prominence to of said 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 semi-finished product are 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 assembly 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 of equipment 10 that sidewall and the lining of tire are supplied with in involved in the present invention being used for respectively.
Table 1
According to the present invention, computer control system is according to the operation of predetermined production method control appliance 10.
In primary importance, said system utilizes the velocity of rotation of depositing reel 6 of brake apparatus 7 adjustings as the function of the semi-finished product amount of uncoiling.
In fact; Said computer control system through making the fabric that gets loose and forever keeping tensioning but the velocity of rotation that changes reel 6 simultaneously act on the brake apparatus 7; Preferably, change along with half-finished amount of supplying with, thereby guarantee that semi-finished product flow to building drum constant and predeterminedly according to predetermined rule.
In fact; A purpose of supply arrangement 10 is to supply with semi-finished product with the constant speed that equates with speed that semi-finished product have at the building drum place, utilizes the rotation of the roller 22 that motor drives that the speed in the decline in said path is passed on the semi-finished product.
For example can be through a plurality of photoelectric tube 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 apparatus 7.In half-finished uncoiling process, when reel 6 emptyings, irradiates light fulgurite and measured value that the current diameter of half-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 apparatus 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 receive 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; When fabric the reducing of its numerical value when reeling that get loose, semi-finished product 2 are carried with constant and predetermined speed, and because the fabric that gets loose involved in the present invention is not extensible and can in material, not produce undesirable stretching.
As stated, because driving, the motor of at least one roller of equipment 10 involved in the present invention also can obtain half-finished constant transport speed.In fact, such motor drives can compensate the drawing effect that on the fabric 5 that gets loose that engages with semi-finished product 2, is applied by beam 20, thereby helps do not having to carry semi-finished product towards building drum 3 under the situation of undesirable stretching.
In the step of assembly technology, computer control system receives the True Data of the parameter of being paid close attention to (above-mentioned speed, position and pulling force); Possibly exist under the situation of deviation with predetermined threshold value, computer control system is carried out necessary adjustment the equipment operation recovery is arrived the condition of programming through relatively storing data and True Data.
Method and apparatus involved in the present invention can be not produce in semi-finished product and stretches and do not make under the situation that half-finished size changes along realizing half-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 semi-finished product that do not have distortion and structural change, the semi-finished product appearance is out of shape and the structural change meeting has a negative impact to final product quality.
For example, when semi-finished product are casingply, do not have vertical expansion can guarantee to form the setting wiry of casing ply, in the step that constitutes carcass, utilize the predetermined density that calculates under the tire operating condition, to obtain the predetermined impedance of carcass.
In addition, must be noted that the not extensible basically fabric of use possibly improve the tension performance of the fabric 5 that gets loose, help very much semi-finished product 2 from depositing all even no stretching uncoiling of reel 6.
The invention is not restricted to foregoing, the present invention also comprises all alternative solutions and the means that those those of ordinary skills that do not describe can infer according to this specification easily although this is.
For example; Equipment 10 can comprise that quantity is different from the roller shown in the figure; Only have two rollers perhaps more than three rollers; Drive as long as at least one is a motor, and the entire arrangement of these rollers can get final product on the fabric that gets loose that can semi-finished product 2 be carried towards building drum 3 with not stretching in the generation tensioning.
