Identical reference numerals are used in the figures for identical or identically acting elements and are not necessarily described again for each figure. It is to be understood that the invention is not limited to the illustrated embodiments and that the described features may be combined or modified without departing from the scope of the invention as defined in the appended claims.FIG. 2 shows a plant for producing components of a pneumatic vehicle tire, which has a work station with a front machine 54. The workstation is in particular a carcass station 50 which has a stationary carcass servicer 52 and the front machine 54 for producing a tire carcass of the pneumatic vehicle tire. The carcass station 50 further includes a second front machine 56 positioned at a first park position 58 and a second park position 60 unoccupied.In this exemplary embodiment, the first front machine 54 has a left machine box 62, a right machine box 64 and a carcass building drum 66, with which in particular first components of the carcass can be produced. After its production, the carcass can be moved in the first front machine 54 by means of a transfer device or by means of a manual transfer to a next station, the cambering station, which is not shown in FIG. 2. Reference numeral 68 denotes the left machine box in the open position.The carcass station 50 with the carcass servicer 52 and the front machines 54 and 56 can be embodied in a manner known per se. The second front machine 56 is preferably constructed identically or identically to the first front machine 54.The second front machine 56 also includes a left machine box 62', a right machine box 64', and a carcass building drum 66' in this embodiment. Reference numeral 68' again designates the left machine box in the open position.If the carcass station 50 is to produce a carcass for others, a second type of tyre, the first front machine 54 with the existing equipment therefor cannot be used any longer, since it is specially adapted for the carcass of the first type of tyre.The first front machine 54, which is positioned on a working position 70, is therefore moved from the working position 70 to the second parking position 60, as indicated by a double arrow P 1. The second front machine 56 is then moved from the first parking position 58 to the working position 70, indicated by a double arrow P 2. The second front machine 56 is already prepared for the second tire type, so that the carcass station 50 is ready for production after the second front machine 56 has moved to the working position 70. This situation is illustrated in FIG. 3. The time during which the carcass station 50 is not ready for production can therefore be kept very short.The first front machine 54, which is now located in the second parking position 60, can already be converted to a carcass of a further, a third tire type during the time when the second front machine 56 produces carcasses for the second tire type, for example by changing the carcass building drum 66 and / or parts relevant to the size of the third tire type.As indicated by the double arrows P 1 and P 2, the second front machine 56 can be moved back to the first parking position 58 when the production of the second tire type in the second front machine 56 is finished, and the first front machine 54 can then be moved back to the working position 70, so that carcasses of the third tire type can subsequently be produced by the carcass station 50. Therefore, one of the two front machines 54 and 56 can be respectively converted during the operation of the carcass station 50, which can therefore remain continuously in operation.The second front machine 56 can be moved arbitrarily between the first parking position 58 and the working position 70 when the first front machine 54 is located in the second parking position 60, and the first front machine 54 can be moved arbitrarily between the working position 70 and the second parking position 60 when the second front machine 56 is located in the first parking position 58, along an axis z, a transfer axis or a transfer path, as indicated in FIGS. 2 and 3 by the double arrows P 1 and P 2.In this exemplary embodiment, the first parking position 58 and the second parking position 60 are each adjacent to the working position 70. The working position 70 is here located directly in front of the carcass machine 64, in contrast to the parking positions 58 and 60 which are further away from the carcass machine 64.A second exemplary embodiment of the installation for producing components of a pneumatic vehicle tire is schematically illustrated in FIGS. 4 and 5. The plant includes in particular a carcass station 86 having the stationary carcass servicer 52 and the first front machine 54. The first front machine 54 is positioned on the working position 70 and is here equipped, for example, for producing a carcass of a fourth tire type of a pneumatic vehicle tire. The carcass station 86 further includes the second front machine 56 positioned at a first park position 80 and a second park position 82 and a third park position 84, both unoccupied.The third parking position 84 is arranged in a row to the working position 70, along an axis z', and the first parking position 80 is arranged parallel to the third parking position 84, in the positive direction of an axis y. The second parking position 82 is likewise arranged parallel to the third parking position 84, but in the negative direction of the axis y, so that the first parking position 80 and the second parking position 82 are each directly adjacent to the third parking position 84. The third parking position 84 is directly adjacent to the working position 70. Axis y and axis z' are preferably two rectangular coordinates, and more preferably transfer axes, along which first front machine 52 and second front machine 54 can be moved.The first front machine 54 can be moved from the working position 70 to the third parking position 84 and then moved either to the first parking position 80 or to the second parking position 82, depending on where the second front machine 56 is positioned: on the first parking position 80 or on the second parking position 82.If the carcass station 86 is to produce a carcass for a fifth type of tyre of a different size, the front machine 54 can no longer be used for this with the existing equipment, since this is specifically adapted for the carcass of the fourth type of tyre.The first front machine 54, which is positioned on the working position 70, is therefore moved from the working position 70 to the third parking position 84, as indicated by a double arrow P 3 in FIG. 4, and subsequently to the second parking position 82, as indicated by a double arrow P 4. Subsequently, the second front machine 56 is moved from the first parking position 80 to the third parking position 84, indicated by a double arrow P 5, and subsequently moved to the working position 70, indicated by the double arrow P 3 and illustrated in FIG. 5.The second front machine 56 is already prepared for the fifth type of tire, so that the carcass station 86 is ready for production after the second front machine 56 has moved to the working position 70, FIG. 5.A third exemplary embodiment of the installation for producing components of a pneumatic vehicle tire is schematically illustrated in FIGS. 6 and 7. The plant includes in particular a carcass station 94 having the stationary carcass servicer 52 and the first front machine 54. The first front machine 54 is positioned on the working position 70 and is here equipped, for example, for producing a carcass of a sixth tire type of a pneumatic vehicle tire. The carcass station 94 further includes the second front machine 56 positioned at a first park position 90 and a second park position 92 that is unoccupied.The first parking position 90 is arranged in a row to the working position 70, along an axis z'', and the second parking position 92 is arranged at an angle to the first parking position 90, in the direction of an axis y'. The first parking position 90 and the second parking position 92 are each adjacent to the working position 70. The axis y' and the axis z" in this exemplary embodiment are preferably two rectangular coordinates, and in particular transfer axes, along which the first front machine 54 and the second front machine 56 can be moved.The first front machine 54 can thereby be moved from the working position 70 to the second parking position 92, as indicated in FIG. 6 by a double arrow P 6, and the second front machine 56 can subsequently be moved from the first parking position 90 to the working position 70, as indicated in FIG. 7 by a double arrow P 7.The second front machine 56 is already prepared for a seventh type of tire having a different size, so that the carcass station 94 is ready for production after the second front machine 56 has moved to the working position 70. The time during which the carcass station 94 is not ready for production can therefore also be kept very short in this exemplary embodiment.The two front machines 54 and 56 are not stationary, but are arranged movably according to the invention and can be moved between the working position and the parking positions, for example using a horizontal or vertical transfer system of the installation, or using a combination of a horizontal or vertical transfer system. The term "movable" is therefore not limited to horizontal movements, but can also involve vertical and other movements.List of reference characters10 Carcass station 12 Carcass servicer 14 Front machine 16 Left machine box (in closed position) 18 Right machine box 20 Carcass building drum 22 Left machine box (in open position) 40 Installation 50 Carcass station 52 Carcass servicer 54 Front machine 56 Front machine 58 Parking area 60 Parking area 62, 62' Left machine box (in closed position) 64, 64' Right machine box 66, 66' Carcass building drums 68, 68' Left machine box (in open position) 70 Working position 80 Parking area 82 Parking area 84 Parking area 86 Carcass station 90 Parking area 92 Parking area 94 Carcass station P1-P7 Double arrows z, z', z" Axes y, y' AxesReferences included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
