Pluralities of casting modules are provided side by side in casting machines used in production of products like water-closet, washbasin, etc. Each casting module can work as a casting machine in a stand-alone manner. There is a mold mechanism in each casting module and these mold mechanisms provide forming of the water-closets.

After the product is obtained, the mold mechanisms existing inside the casting modules are opened and the product is released. When the obtained product is first removed from the mold, it is brittle and therefore, handling of the product by the operators may lead to breakage of the products. In order to avoid this problem, various product handling mechanisms which have been developed are used.

DETAILED DESCRIPTION OF THE INVENTION In this detailed description, the subject matter product handling vehicle (30) is explained with references to examples without forming any restrictive effect only in order to make the subject more understandable.

In Figure 1 , the general view of the casting machine (10) where the subject matter product handling vehicles (30) are used is given. The casting machine (10) consists of casting modules (1 1 ) provided side by side. There is a mold mechanism (20) inside each casting module (1 1 ). Said mold mechanisms (20) comprise an upper mold (21 ), a lower mold (22) provided under said upper mold (21 ) and lateral molds (23) provided at the two sides of the lower mold (22) and the upper mold (21 ) mutually. The water-closet to be produced is shaped between the molds in this mold mechanism (20). The formed product is handled by means of the product handling vehicles (30) through the mold mechanism (20) and it is afterwards transferred to the process by the operators.

The general views of the product handling vehicles (30) in different positions are given in Figure 3, 4 and 5. The product handling vehicles (30) are connected onto the floor in a manner corresponding to the next position after the casting process of each casting module (1 1 ) provided on the casting machine (10) is completed. The connection of product handling vehicles (30) onto the floor is realized through a floor plate (31 ). An orthogonal movement mechanism (32) is connected onto said floor plate (31 ). On said orthogonal movement mechanism (32), there is a horizontal movement mechanism (33) and said horizontal movement mechanism (33) is connected to a carrier plate (34). The formed product is handled from the mold mechanism (20) by means of said carrier plate (34). Positioning of the carrier plate (34) inside the mold mechanism (20) and the outward movement are provided by the orthogonal movement mechanism (32) and by the horizontal movement mechanism (33). The orthogonal movement mechanism (32) comprises a casing (321 ) seated onto the floor plate (31 ), guide rails (322) connected along the length of the casing (321 ) on the two sides of said casing (321 ), and a vehicle plate (326) which is movable upwardly-downwardly in the orthogonal direction on the guide rails (322). The movement of said vehicle plate (326) on the guide rails (322) is provided by means of vehicles (325) connected at the four corners and under the vehicle plate (326). Guidance of the vehicle plate (326) is realized by means of orthogonal drive mechanism (323) comprising a screwed shaft, connected to the casing (321 ) and to the vehicle plate (326). The orthogonal movement mechanism (32) provides upward-downward movement of the horizontal movement mechanism (33) and of the carrier plate (34) provided at the horizontal movement mechanism (33), and the orthogonal movement mechanism (32) provides operation conditions which are compliant to the heights of different mold mechanisms (20). Height adjustment in accordance with the mold type is provided by means of a servo motor (not illustrated in the figures). The horizontal movement mechanism (33) comprises a fixed bearing (331 ) connected onto the vehicle plate (326) and a telescopic beam (334) positioned on said fixed bearing (331 ). Said telescopic beam (334) is moved forwardly-backwardly towards the casting modules (1 1 ) by a horizontal drive mechanism (332) inside the fixed bearing (331 ). This movement is provided by a main motor (333). Here, said horizontal drive mechanism (332) comprises the rack gear system (not illustrated in the figures) where said main motor (333) provides movement. There is a beam guide (335) positioned on the telescopic beam (324) along the length of the telescopic beam (324). On said beam guide (335), the carrier plate (34) can be moved forwardly-backwardly towards the casting modules (1 1 ) in an independent manner from the movement of the telescopic beam (334).

The carrier plate (34) comprises a movement plate (342) placed onto the beam guide (335) and a handling plate (341 ) positioned on said movement plate (342) and where the product is placed. The movement of the movement plate (342) in the beam guide (334) is realized by means of a movement chain (343) provided in an embedded manner in the telescopic beam (334) in a substantially parallel manner to said beam guide (335). The guidance of said movement chain (343) is provided by a drive motor (344) positioned at the end of the telescopic beam (334).

In order to handle the product, formed inside the mold mechanism (20), from the casting module (1 1 ), first of all, the upper mold (21 ) and the lower mold (22) are opened and the lateral molds (23) stay without being opened. The orthogonal movement mechanism (32) moves the vehicle plate (326) downwardly or upwardly in order to adjust the position of the vehicle plate (326) with respect to the mold height and it provides the carrier plate (34) to be aligned with respect to the mold mechanism (20). Afterwards, the horizontal drive mechanism (33) moves the telescopic beam (334) forwardly towards the casting module (1 1 ). The carrier plate (34) advanced towards the front of the casting module (1 1 ) by means of telescopic beam (334) is placed under the formed product by means of the drive motor (344) and the movement chain (343). At the continuation of the process, the lateral molds (23) are opened and the product stays on the handling plate (341 ). The product which stays on the handling plate (341 ) is removed from the casting module (1 1 ) by means of the backward movement of the carrier plate (34) and the telescopic beam (334). After this step, the carrier plate (34) is drawn to the backmost position in the product handling vehicle (30) and it is waited in this position until the end of the next shaping process. After the next shaping process is completed and after the lower molds (22) and the upper molds (21 ) are opened, the product on the handling plate (341 ) is handled by the operator. All product handling vehicles (30) related to the casting machine (10) have separate control units and all of them operate simultaneously. In case different product types are worked on in the casting modules (1 1 ), even if the products are obtained in different time durations, all product handling vehicles (30) are waited, and after the final product is shaped, all lower molds (22) and all upper molds (21 ) are opened simultaneously, and the product handling vehicles (30) are activated. Casting process is begun automatically in all casting modules (1 1 ), where production will be realized, after the information, which is related to removal of the product by the vehicles (30) which simultaneously begin the process, reaches the main PLC. In the product handling processes realized in this manner, since all product handling vehicles (30) realize process simultaneously and since the new casting process begins simultaneously in all casting modules (1 1 ) after the product handling process, the process durations are shortened and the production in unit time is increased and thereby, the production costs are reduced.

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.
