characterized in that

Surprisingly, it was found within the scope of the present invention that the placement behavior of two tire components and thus their positions when placed on a building drum are different even if these two tire components are produced from the same rubber mixture batch. It is therefore assumed that even two tire components with the same rubber composition due to very small deviations in the manufacturing process show a different behavior when placing. It is therefore necessary to also place such tire components consisting of the same rubber mixture on a tire building drum by means of a device according to the invention with a plurality of tire component positioning units. Of course, this is all the more true if the tire components are made from different materials or different rubber compounds.

Within the scope of the present invention, a device according to the invention can also have more than two above-described tire component positioning units, preferably at least one tire component positioning unit per tire component of the subsequently produced green tire.

An example of a guide component described above is the product with the product name "MC-300 Automatic Pick and Place" from Manncorp, which can pick up and put down components. However, further embodiments of such tire component positioning units are known to those skilled in the art.

An example of a receiving component described above with a suction sub-component described below is the bellows suction gripper with the product name bellows suction gripper SPB1 (1.5 folds) from Schmalz. However, further embodiments of such tire component positioning units are known to those skilled in the art.

• - die erste Reifenbauteilpositioniereinheit eingerichtet ist, ein Reifenbauteil auf eine Seite der Oberfläche der Aufbautrommel oder auf ein auf dieser einen Seite der Oberfläche der Aufbautrommel liegendes Reifenbauteil aufzulegen, und/oder
• - die zweite Reifenbauteilpositioniereinheit eingerichtet ist, ein gleichartiges Reifenbauteil auf die andere Seite der Oberfläche der Aufbautrommel oder auf ein auf der anderen Seite der der Oberfläche Aufbautrommel liegendes Reifenbauteil aufzulegen.

A device according to the invention is preferred as described above or as described above as preferred, wherein

• the first tire component positioning unit is set up to place a tire component on one side of the surface of the building drum or on a tire component lying on this one side of the surface of the building drum, and / or
• the second tire component positioning unit is set up to place a tire component of the same type on the other side of the surface of the building drum or on a tire component lying on the other side of the building drum surface.

• - sowohl das besagte eine Reifenbauteil als auch das besagte gleichartige Reifenbauteil ein Seitenwandbauteil zur Herstellung desselben Reifenrohling,
• - sowohl das besagte eine Reifenbauteil als auch das besagte gleichartige Reifenbauteil ein Wulstbauteil zur Herstellung desselben Reifenrohling

oder

• - sowohl das besagte eine Reifenbauteil als auch das besagte gleichartige Reifenbauteil ein Schulterbauteil zur Herstellung desselben Reifenrohling

sind, wobei bevorzugt sowohl das besagte eine Reifenbauteil als auch das besagte gleichartige Bauteil aus dem gleichen Endlosstreifen, besonders bevorzugt dem gleichen Abschnitt des Endlosstreifens, hergestellt wurden.In the context of the present invention, the expression “tire component of the same type” encompasses, in particular, those tire components, where either

• - both said one tire component and said tire component of the same type are a sidewall component for producing the same green tire,
• - Both said one tire component and said tire component of the same type are a bead component for producing the same green tire

or

• - Both said one tire component and said tire component of the same type are a shoulder component for producing the same green tire

are, wherein preferably both said one tire component and said component of the same type were produced from the same endless strip, particularly preferably the same section of the endless strip.

A particularly common reason why even those tire construction parts that have arisen from the same extruded endless strip have a different behavior when placed is the always the same direction of rotation of the extruder screw with which the endless strip was produced. The direction of rotation of the extruder has the effect that the two sides of an extruded endless strip have different properties, such as, for example, different porosity, density or shrinkage of the respective side of the extruded endless strip. A so-called banana effect can also result here. However, the causes described above are not the only causes for a different behavior of two tire components made from the same rubber mixture when placed on a building drum.

Therefore, the improved placement of a tire component by means of a device according to the invention results in a particularly robust pneumatic vehicle tire and thus the service life of the pneumatic vehicle tire is extended.

Up to now, errors resulting from the above-mentioned reasons have to be carried out manually by a worker.

In the context of the present invention, the surface of a building drum has one side and another side, the two surface sides being separated by the circumferential center line of the building drum. In the context of the present invention, the circumferential center line of the building drum runs on the straight line on the surface of a building drum, said line being created by the intersection of a cross-sectional plane perpendicular to the axis of rotation of the building drum with the surface of the building drum and the surface of the building drum in two equally sized sides , the said one and the said other side, divides.

A device according to the invention is preferred as described above or as described above as preferred, the second drive being controllable or regulatable with said control unit.

One advantage of the aspect of the present invention described above is that a control unit can control both drives as described above and can thus correct both the position of the first receiving component and the position of the second receiving component. This leads to a faster correction and also to more possibilities for adaptation when placing the respective tire component by means of the first and the second tire component positioning unit.

A device according to the invention is preferred as described above or as described above as preferred, the first and / or second receiving component comprising intake subcomponents, the intake subcomponents being set up to lift a tire component by generating a negative pressure.

An advantage of the above-described aspect of the present invention is that intake subcomponents can be reused without any problems and, moreover, do not leave any damage in the tire component.

Particularly preferred is a device according to the invention as described above or as described above as preferred, the first and / or second tire component positioning unit additionally having sensors for determining at least one edge of a tire component, preferably sensors for determining at least one edge of a tire component received by means of the first or second receiving component , wherein said edge is preferably the front edge and / or the rear edge of the respective tire component.

One advantage of the above-described aspect of the present invention is that by detecting corresponding measurement signals from the above-described sensors, the control unit can not only control the position of the first and second recording components, but also regulate them. This leads to a considerable advantage, particularly in the case of the differences described below and described above in the rubber mixtures and their behavior.

As a result of the regulation, a reduction in the variation both of the splices of the components placed in parallel with one another and of the splice overlap in general can be achieved. This has advantages with regard to the required tire geometry for the aspects of imbalance and optics.

A device according to the invention as described above or as described above as preferred or as described above as particularly preferred is also particularly preferred, the control unit being set up to process the measurement signals from the sensors and, depending on the measurement signals received from the sensors, the position of a leading edge and / or to regulate a rear edge of a tire component positioned by means of the first and / or second receiving component in such a way that the front edge and the rear edge of the same positioned tire component lie against one another so that they can be spliced.

An advantage of the aspect of the present invention described above is that, in particular when a rear and front edge of a tire component is placed on the vehicle in an improved manner by means of a device according to the invention, a pneumatic vehicle tire becomes particularly robust and its service life is thus extended. It is also particularly advantageous here that the device according to the invention can be fully automated by means of the use of the sensors described above and thus no longer requires the intervention of a worker. This improves work safety and the process flow.

The front and rear edges can be laid next to one another in different ways. Two tire components can be positioned with respect to one another, for example, in that the position of their respective leading edge is adapted to one another by means of a device according to the invention. Alternatively, however, it is also possible that the front edges are first placed on the building drum without a correction and the respective receiving component then places the rear edge of the said tire components and, with the aid of the sensors described above, measures the offset of the two said front edges and the two rear edges. It can happen here that the measurement of the sensors in question shows that one tire component is shorter than the other for the reasons described above. A device according to the invention is therefore preferably set up in such a way that the receiving components placed on the rear edges then pick up and stretch the respectively shorter tire component again and / or that by means of an additional roll-out unit for rolling out already placed tire components, the already placed tire components roll out so far that the shorter tire component opens the building drum is stretched accordingly. An example of such a roll-out unit is shown in 1 until 4th and their figure descriptions in the document US2201470A described.

A device according to the invention is preferred as described above or as described above as preferred, the tire component being a side wall component for use in a pneumatic vehicle tire.

An advantage of the above-described aspect of the present invention is that the above problems occur in particular with side wall components, since side wall components are mostly produced from the same continuous strip, but are placed on the respective opposite sides of the building drum.

A device according to the invention is preferred as described above or as described above as preferred, the first and / or second tire component positioning unit being arranged radially above the building drum.

An advantage of the above-described aspect of the present invention is that the tire components can be placed more precisely when the tire component positioning units are arranged radially above the building drum.
