Description

A TIRE PRODUCTION MACHINE

TECHNICAL FIELD

The present invention relates to a tire production machine.

PRIOR ART

Tires are elements which provide contact of vehicles to ground and which provide movement of vehicles. Thus, tires have very important functions for the vehicles to reach the desired comfort and safety criteria. Therefore, tires shall have some characteristics in the direction of these criteria. In order to produce tires with these characteristics, tires shall be formed by pluralities of layers with different characteristics and these layers shall be associated with each other in a suitable manner. Tire production machines, which are used for production of tires, join the layers produced in pluralities of lines and provide final form to the tire. However, incompliancies, existing between production durations of the layers of said structure and the intermediate joining durations of the layers, lead to extension of the production duration of the tire production machines. Moreover, a single type of tire can be produced in the same machine. When the product is desired to be changed, product change durations lead to serious time and labor losses.

In the American patent with no US4230517, a modular tire production machine is disclosed.

As a result, because of all of the abovementioned problems, an improvement is required in the related technical field.

BRIEF DESCRIPTION OF THE INVENTION

The present invention relates to a tire production machine, for eliminating the above mentioned disadvantages and for bringing new advantages to the related technical field.

An object of the present invention is to provide a tire production machine where the waiting durations occurring in production are minimized and where the final product amount produced per unit time is increased. In order to realize all of the abovementioned objects and the objects which are to be deducted from the detailed description below, the present invention is a tire production machine having an outer layer preparation unit, an inner layer preparation unit, a lateral material carrier, and a carrying and joining unit where the materials, coming from the outer layer preparation unit, the inner layer preparation unit and the lateral material carrier, are brought together. Accordingly, the subject matter tire production machine comprises at least two joining cylinders provided in the outer layer preparation unit in order to provide preparation of the outer layers of at least two tires simultaneously, and at least two drums configured on a drum carrier, provided in the carrying and joining unit, such that the positions of said drums can be changed. Thus, the processes of inner layer preparation, outer layer preparation and joining of multiple tires can be realized simultaneously. By means of this, the waiting durations between the process steps are eliminated and the amount of final product produced per unit time is increased.

In a possible embodiment of the present invention, the drums are configured to displace between a first position, whereon the inner layers are wrapped, and at least one second position where the lateral materials are added, and at least one third position where the inner layer, the outer layer and the lateral materials are joined. Thus, the steps of joining the inner layer and the materials added thereon can be realized in an independent manner from each other at different positions.

In a possible embodiment of the present invention, the drums are configured to arrive at a fourth position where the tire, which obtains its final form, can be removed. Thus, while joining processes are continuing, the completed product is removed from the machine.

In a possible embodiment of the present invention, the drum carrier, whereon the drums are positioned, is positioned within a predetermined arrangement around a center axis and the drum carrier is configured to make rotational movement at a center axis. Thus, the positions of the drums can be changed only by means of the rotation of the drum carrier.

In a possible embodiment of the present invention, in order to provide transfer of the materials, positioned on the joining cylinders, to the drums, carriers are provided which are in number equal to the number of joining cylinders. Thus, the step of the transfer of the outer layers, prepared on the joining cylinders, to the drums by means of carriers and the step of waiting of the outer layer, existing in the other carrier, in a ready manner when the outer layer in one of the carriers is transferred to the drum existing at the third position, and the step of preparing new outer layers in the joining cylinders can be provided while these steps are being realized.

In a possible embodiment of the present invention, the joining cylinders and the carriers are provided in a coaxial manner with the drum existing at the third position. Thus, a linear movement is realized on a carrier rail and the outer layer is taken from the joining cylinder and said outer layer is transferred to the drum existing at the third position. This provides the movement to be simple and rapid.

In a possible embodiment of the present invention, the drum, existing at the first position, is provided in the vicinity of the inner layer preparation unit. Thus, the inner layers prepared in the inner layer preparation unit can be directly onto the drum existing at the first position.

In a possible embodiment of the present invention, at least one lateral material carrier is provided in the vicinity of the drum existing at the second position, in order to provide transfer of lateral materials to said drum.

In a possible embodiment of the present invention, said lateral material carrier is provided in a coaxial manner with the drum existing at the second position.

In a possible embodiment of the present invention, there is at least one joining unit provided in the vicinity of the drum provided at the third position.

DETAILED DESCRIPTION OF THE INVENTION

In this detailed description, the subject matter tire production machine (10) is explained with references to examples without forming any restrictive effect only in order to make the subject more understandable. The subject matter tire production machine (10) essentially has an outer layer preparation unit (20), an inner layer preparation unit (40) and a carrying and joining unit (60).

The outer layer preparation unit (20) has at least two joining cylinders (30). Said joining cylinders (30) are associated with one each first layer lines (21), a second layer wrapping unit (22) and a third layer line (23). In a possible embodiment of the present invention, the first layer wrapped onto the joining cylinder (30) from the first layer line (21) comprises steel- supported rubber. The second layer, wrapped onto the first layer by the second layer wrapping unit (22), comprises stranded rubber. The third layer, coming from the third layer line and wrapped onto the second layer, has a threaded part which remains on the outermost side of the tire.

The carrying and joining unit (60) has at least two carriers (61) provided in the vicinity of the joining cylinders (30) and provided so as to move on a rail (62). Moreover, at least three drums (65) are provided on a drum carrier (64). Said drums (65) are provided at a first position (I), a second position (II) and a third position (III). In a possible embodiment of the present invention, there is an additional drum (65) provided at a fourth position (IV). According to said embodiment, the drum carrier (64) is essentially embodied to rotate in a center axis (a) which passes through the center thereof. Thus, when the drum carrier (64) is rotated, the drums (65) realize rotational movement around a center axis (a) so as to displace between the first position (I), the second position (II), the third position (III) and the fourth position (IV).

In the subject matter tire production machine (10), the drum (65) provided at the first position

(I) is essentially provided in the vicinity of the inner layer preparation unit (40). Thus, the inner layer prepared in the inner layer preparation unit (40) can be directly wrapped onto the drum (65) provided at the first position (I).

There is at least one lateral material carrier (50) provided in a coaxial manner with the drum (65) provided at the second position (II). In a possible embodiment of the present invention, two lateral material carriers (50) are provided. Thus, the lateral materials positioned on the lateral material carrier (50) are transferred to the drum (65) provided at the second position

(II). The lateral materials are provided to form the lateral sides of the tire.

The drum (65) provided at the third position (III) is essentially provided in a coaxial manner with the carriers (61). Thus, the outer layers carried on the carriers (61) are transferred to the drum (65) provided at the third position (III). Moreover, by means of a joining unit (63) provided in the vicinity of the drum (65) existing at the third position (III), the materials provided on the drum (65) existing at the third position (III) are joined and the tire takes its final form.

The drum (65) provided at the fourth position (IV) is essentially used for removing the tire, which has obtained its final form, from the tire production machine (20). In another possible embodiment of the present invention, this process can be realized on the drum (65) provided at the third position (III).

The operation of the subject matter tire production machine (10) is essentially realized as follows.

In the outer layer preparation unit (20), the first layer, the second layer and the third layer are wrapped onto the joining cylinders (30). Thus, the outer layers, which are to be used for at least two tires simultaneously, become ready. Afterwards, the outer layers are transferred onto the carrier (61), and the outer layer is started to be prepared for the tires which is in number equal to the number of re-joining cylinders (30) on the joining cylinders (30). In a simultaneous manner with the beginning of preparation of the outer layers, the inner layer prepared in the inner layer preparation unit (40) is wrapped onto the drum (65) provided at the first position (I). Afterwards, the drum carrier (64) is rotated at a predetermined amount and the drum (65), whereon the inner layer is wrapped, is passed to the second position (II) and a drum (65), having no layer wrapped thereon, is passed to the first position (I). At the continuation thereof, while the inner layer is wrapped onto the drum (65) existing at the first position (I), the lateral materials, provided on the lateral material carrier (50), are applied onto the drum (65) existing at the second position (II). Afterwards, the drum carrier (64) is again rotated at a predetermined amount, the drum (65) existing at the first position (II) passes to the second position (II) and the drum (65) existing at the second position (II) passes to the third position (III). While the drums (65) are at these positions, the inner layer is applied onto the drum (65) existing at the first position (I), lateral materials are added onto the drum (65) existing at the second position (II) and the outer layer existing on the carrier (61) is added onto the drum (65) existing at the third position (III) and all materials are joined by means of the joining unit (63) and the tire is brought to final form.

After the tire is brought to final form, the removal of the tire from the tire production machine (10) can be realized in the form of two applications. In the first application, the tire is removed from the drum (65) while the tire is at the third position (III). In the second application, the drum carrier (64) is rotated at a predetermined amount and the tire, which has been brought to final form, is brought to the fourth position (IV) and it is removed from the drum (65).

Thanks to said structure of the subject matter tire production machine (10), the waiting durations which occur during production are eliminated. In other words, in a possible embodiment of the present invention, since two each carriers (61) and two each joining cylinders (30) are provided and since different process steps can be applied simultaneously on the four drums (65) provided on the drum carrier (64), the incompliancies between the preparation times and joining times of the inner layers and outer layers are eliminated. Thus, there remains no need to wait for the completion of the other step for realizing a process step.

The protection scope of the present invention is set forth in the annexed claims and cannot be restricted to the illustrative disclosures given above, under the detailed description. It is because a person skilled in the relevant art can obviously produce similar embodiments under the light of the foregoing disclosures, without departing from the main principles of the present invention.
