DETAILED DESCRIPTION OF THE INVENTION

[0039] In this detailed description, the subject matter transfer unit (30) is explained with references to examples without forming any restrictive effect only in order to make the subject more understandable.

[0040] As can be seen in FIG. 1, the subject matter transfer unit (30) is essentially positioned between the vacuuming machine (10) and the roll machine (20). In other possible embodiments of the present invention, a different line is added to an end of the transfer unit (30), and the bed can be transferred without forming roll.

[0041] As can be seen in FIGS. 2 and 3, the subject matter transfer unit (30) has a chassis (31). Said chassis (31) comprises pluralities of profiles. The transfer unit (30) has at least one first conveyor (32) and at least one second conveyor (33). The first conveyor (32) and the second conveyor (33) are positioned side by side such that there is a predetermined distance in between. The first conveyor (32) and the second conveyor (33) have pluralities of conveyor rolls (34). The conveyor rolls (34), provided on the first conveyor (32), extend in a parallel manner to each other. The conveyor rolls (34), provided on the second conveyor (33), extend in a parallel manner to each other. Moreover, the conveyor rolls (34), which are provided on the first conveyor (32) and on the second conveyor (33), extend in the same direction. The first conveyor (32) and the second conveyor (33) are configured in a manner providing movement in the same direction or in opposite directions. The topmost parts of the conveyor rolls (34) are provided on the same plane and this plane is defined as an operation plane. In another possible embodiment of the present invention, the first conveyor (32) and the second conveyor (33) can be conveyors with belt.

[0042] A side of the first conveyor (32) and the second conveyor (33) is defined as an input side (36). Said input side (36) is connected to the vacuuming machine (10). An adjacent side of the input side (36) is defined as a discharge side (37). Said discharge side (37) is connected to the roll machine (20).

[0043] As can be seen in FIGS. 4a and 4b, there is a centering arm (40) provided at the upper side of the operation plane. Said centering arm (40) is connected to the chassis (31) from one side by means of a rotary hinge (44). Thus, the centering arm (40) realizes a rotational movement in the axis of the rotary hinge (44) and the centering arm (40) may displace between an operation position (I) where the centering arm (40) is orthogonal to the operation plane and a waiting position (II) where the centering arm (40) diverges from the operation plane. This movement of the centering arm (40) is provided by means of a first positioning cylinder (42) connected to the chassis (31) from one end and connected to the centering arm (40) from the other end. There is at least one rotary holder (41) provided at the idle end of the centering arm (40). Said rotary holder (41) is configured to be able to rotate in the extension axis of the centering arm (40). There is at least one first press cylinder (43) provided on the centering arm (40). Said first press cylinder (43) moves in a manner approaching the rotary holder (41) to the operation plane and in a manner providing diverging of the rotary holder (41) from the operation plane. In another possible embodiment of the present invention, the rotary holder (41) can rotate with the drive to be received from a drive source.

[0044] As can be seen in FIG. 5, there is at least one correction unit (50) provided on the side opposite to the input side (36). Said correction unit (50) has a correction wall (51). Said correction wall (51) is configured to be able to rise over and lower below the operation plane. In a possible embodiment of the present invention, the correction wall (51) is connected to a lifting cylinder (52) and the correction wall (51) displaces vertically thanks to the lifting cylinder (52). In alternative embodiments, movement can be provided by using different movement units.

[0045] As can be seen in FIG. 6a, there is at least one press arm (60) provided in the upper vicinity of the operation plane. Said press arm (60) at least partially extends along the width of the transfer unit (30). The press arm (60) is configured to move between a folding position (III) where it approaches the operation plane and a free position (IV) where it diverges from the operation plane. The press arm (60) is provided on an arm holder (62) connected onto an arm carrier (61) so as to have rotational freedom which is essentially connected to the chassis (31) so as to have rotational freedom. In other words, the press arm (60) is connected to one each arm holders (62) from the two ends thereof and the arm holders (62) are connected to the chassis (31) by means of arm carriers (61). There is at least one second positioning cylinder (63) connected to the arm carrier (61) from one end and connected to the chassis (31) from the other end. As said second positioning cylinder (63) is opened and closed, the arm carrier (61) displaces between the folding position (III) and the free position (IV).

[0046] The arm holder (62) is connected to the arm carrier (61) so as to have rotational freedom. The arm holder (62) is connected to the arm carrier (61) from a predetermined distance to an end of the arm carrier (61). There is at least one second press cylinder (64) connected to the arm carrier (61) from one end and connected to the arm holder (62) from the other end. As the second press cylinder (64) is opened and closed, the press arm (60), provided on the arm holder (62), can displace in an independent manner from the arm carrier (61).

[0047] As can be seen in FIGS. 6b, 6c, 6d and 6f, the subject matter transfer unit (30) has at least one folding mechanism (70). In said folding mechanism (70), there is at least one folding profile (72) extending at least partially along the width of the transfer unit (30) between the conveyor rolls (34). The folding profile (72) is configured to displace between a lower position (V) where it stays under the operation plane, a first position (VI) where it rises over the operation plane at a predetermined amount, a second position (VII) where it displaces horizontally at a predetermined amount with respect to the first position (VI) and a press position (VIII) where it approaches at a predetermined amount with respect to the operation plane from the second position (VII). In a possible embodiment of the present invention, pluralities of folding profiles (72) are provided such that there is a predetermined distance in between. The folding profiles (72) are connected to each other by means of profile carriers (73) essentially provided at the ends thereof. There is at least one each vertical movement cylinders (71) connected by means of the folding profile (72). Moreover, the folding mechanism (70) has a horizontal movement rail (74) connected to the chassis (31). The folding mechanism (70) is configured to be able to displace in the direction of the horizontal movement rail (74) by means of the movement received from a drive element (not shown in the figures).

[0048] As can be seen in FIG. 7, the subject matter transfer unit (30) has at least one discharge mechanism (80). Said discharge mechanism (80) has at least one pushing wall (81) configured to be able to linearly displace in the extension direction of the conveyor rolls (34). Said pushing wall (81) is moved by a linear movement unit (82).

[0049] In the light of the abovementioned structural details, the subject matter transfer unit (30) operates as follows.

[0050] With reference to FIGS. 4a and 4b, the bed coming from the vacuuming machine (10) enters into the transfer unit (30). The first conveyor (32) and the second conveyor (33) rotate in the same direction in the transfer unit (30) and advance the bed. The position of the bed is monitored by means of at least one measurement sensor (35) provided between the first conveyor (32) and the second conveyor (33). The bed length is measured by means of pluralities of measurement sensors (35), and when the center of the bed coincides with the extension direction of the centering arm (40) in the operation position (I), the first conveyor (32) and the second conveyor (33) are stopped. Afterwards, the centering arm (40) is brought to the operation position (I) by means of movement of the first positioning cylinder (42). Afterwards, the first press cylinder (43) and the rotary holder (41) at least partially exert pressure onto the bed. In other words, the bed is held from the center thereof by means of the rotary holder (41).

[0051] After the bed is held from the center thereof, the first conveyor (32) and the second conveyor (33) move by rotating in directions which are opposite to each other. By means of this, the bed begins rotating in the axis of centering arm (40). Thus, the bed is rotated 90 degrees. Thus, the bed, extending in the direction of width of the transfer unit (30), becomes extending in the direction of the length of the transfer unit (30). When the bed exits the vacuuming machine (10) in a longitudinally extending manner, the rotation process of the bed can be canceled.

[0052] With reference to FIG. 5, in a possible embodiment of the present invention, in order to provide position control of the bed, the first conveyor (32) and the second conveyor (33) operate in the same direction and drive the bed forwardly and the bed can be rested onto the correction wall (51). After the bed is rested onto the correction wall (51), since the first conveyor (32) and the second conveyor (33) continues operation, the bed is turned into a flat form. Afterwards, the first conveyor (32) and the second conveyor (33) operate in a rearward manner and they bring the center of the bed to the same level as the condition of the press arm (60) where the press arm (60) comes to folding position (III). Afterwards, as can be seen in FIG. 6a, by means of the second positioning cylinder (63) and the second press cylinder (64), the press arm (60) presses the bed in a manner passing through the center of the bed.

[0053] With reference to FIGS. 6b and 6c, after the press arm (60) holds the bed from the center axis thereof, the folding profiles (72) of the folding mechanism (70) are pushed by the vertical movement cylinders (71) and are brought from the lower position (V) to the first position (VI) and provide upward lifting of one side of the bed. Afterwards, with reference to FIGS. 6d and 6e, the folding mechanism (70) slide on the horizontal movement rail (74) and comes to the second position (VII) and folds one half of the bed onto the other half of the bed through the press arm (60). Afterwards, by means of the movement of the second positioning cylinder (63) and of the second press cylinder (64), the press arm (60) is removed from the bed. At the continuation, with reference to FIGS. 6f and 6g, the vertical movement cylinder (71) lowers the folding profiles (72) downwardly and brings the folding profiles (72) to the press position (VIII) and presses onto the folded bed and provides the folding to be permanent.

[0054] Afterwards, the folding profile (72) returns to the lower position (V).

[0055] With reference to FIG. 7, after the folding process of the bed is completed, the pushing wall (81) of the discharge mechanism (80) is pushed by the linear movement unit (82) and it is stopped onto an edge of the bed and pushes the bed and it reaches the bed to the roll machine (20) provided in the vicinity of the transfer unit (30).

[0056] In a possible embodiment of the present invention, after the bed is folded, as the first conveyor (32) and the second conveyor (33) operate in the same direction, it is possible to transfer the bed to a different conveyor which is to be provided at the opposite side of the vacuuming machine (10) and to transfer the bed without forming roll.

[0057] Thanks to the subject matter transfer unit (30), it is possible to rotate the bed, to fold the bed, to crush the bed and to transfer the bed to the roll machine (20) at the same location. Thus, there remains no need to use different units for each process and the operation of the system is provided in a narrower region.

[0058] Moreover, the transfer unit (30) can be operated in a synchronized manner by means of machines where the bed is vacuumed in a traverse or longitudinal manner. In other words, a compact transfer unit (30) is obtained which can operate together with different types of vacuum machines (10).

[0059] 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.
