DETAILED DESCRIPTION OF THE INVENTION
In this detailed description, the subject matter part transfer mechanism (1 ) is explained with references to examples without forming any restrictive effect only in order to make the subject more understandable.
In Figure 1 , a representative perspective view of the form where the subject matter part transfer mechanism (1 ) is associated with the body (30) is given. The present invention relates to a part transfer mechanism (1 ) which can provide transfer of parts which are narrower than the width of the part which can be transferred to the bending area in CNC bending machines. In said part transfer mechanism (1 ); there is a vacuum mechanism (20) which can be associated to a stop mechanism (40) provided on a body (30) provided in the CNC bending machine. In said vacuum mechanism (20), there is at least one vacuum pad (22) configured to provide transfer of parts, which have predefined width, to the bending area. Moreover, in the part transfer mechanism (1 ), as can be seen in Figure 2 and 3, there is a movement mechanism (10) configured to provide movement of the vacuum mechanism (20) between a park position (I) and the position where the vacuum mechanism (20) associated to the stop mechanism (40).
In Figure 4, a representative perspective view of the subject matter part transfer mechanism (1 ) is given. In said movement mechanism (10), there is a connection surface (1 1 ) for providing connection onto the body (30). In the movement mechanism (10), there is a movable surface (12) for providing association with the vacuum mechanism (20). There is a guide (14) provided between said connection surface (1 1 ) and said movable surface (12) for providing association thereof. Said guide (14) can enter into and exit a guide bearing (15) provided on the connection surface (1 1 ). For providing movement of the guide (14), there is at least one drive element (13) associated with the guide (14). Thus, the movement of the vacuum mechanism (20), associated with the movable surface (12), is provided between the park position (I) and the stop mechanism (40).
In Figure 5, a lateral representative cross-sectional view of the form of the vacuum mechanism (20) positioned on the stop mechanism (40) in the subject matter part transfer mechanism (1 ) is given. There is at least one guide element (16) provided on said movable surface (12) for providing correct positioning of the vacuum mechanism (20) positioned on the stop mechanism (40) for transferring part to the bending area. Said guide element (16) enters into at least one locking part (41 ) provided on the stop mechanism (40). Afterwards, as seen in Figure 6, in order to provide separation of the vacuum mechanism (20) from the movable surface and in order to provide locking of the vacuum mechanism (20) onto the stop mechanism (40), movement is provided to at least one lower locking element (23) provided in the vacuum mechanism (20) in at least one stop drive element (42) provided in the stop mechanism (40). Said lower locking element (23) is associated with at least one compression element (43), provided at the stop mechanism (40), after the received movement. Thus, the vacuum mechanism (20) is locked onto the stop mechanism (40). Afterwards, the movement mechanism (10), which leaves the vacuum mechanism (20) onto the stop mechanism (40), returns back to the park position (I). The vacuum mechanism (20) can move in the direction of the bending axis together with the stop mechanism (40) whereon it is locked. The vacuum mechanism (20), connected to the stop mechanism (40) and which obtains approaching characteristic to the bending axis, provides bending of the sheet part having a width which is lower than a specific width.
There is at least one vacuum pad (22) in the vacuum mechanism (20) in order to provide holding of the sheet part, which is to be bent, by the vacuum mechanism (20). Said vacuum pads (22) vacuum and hold the sheet part. In order to provide air transfer to the vacuum pads (22), there is at least one air passage part (44) provided on the stop mechanism (40). The air, transferred from said air passage part (44), is transferred to the air transfer element (21 ) positioned at the vacuum mechanism (20), in order to transfer said air to the vacuum pads (22). Said air transfer element (21 ) has a bored structure and provides transfer of air to the vacuum pads (22) through the air passage part (44). The lower locking element (23), connected onto the air transfer element (21 ) and which provides locking of the vacuum mechanism (20) to the stop mechanism (40), has a bored structure and permits air passage. At least one sealing element (45) is provided for providing air sealing between the air passage part (44) and the lower locking element (23).
In Figure 7 and 8, the top and bottom representative perspective views of the subject matter part transfer mechanism (1 ) are given. The vacuum pads (22) provided from the vacuum mechanism (20) is positioned on at least one vacuum pad connection part (27). Said vacuum pad connection part (27) comprises two parts as the right connection part (271 ) and the left connection part (272). Said right connection part (271 ) and said left connection part (272) are connected to at least one vacuum carriage plate (25). In order to provide adjustment of the height of said vacuum carriage plate (25) in a linear manner downwardly and upwardly, there is at least one height adjustment element (24) associated with the vacuum carriage plate (25). There is at least one height drive element (26) providing movement to said height adjustment element (24). The height adjustment element (24) moved by said height drive element (26) provides the vacuum carriage plate (25) to be brought to the suitable position according to the dimensions of the sheet part to be bent. Vacuum pads (22) are provided in an embedded manner on the front surface (273) and on the lower surface (274) of the right connection part (271 ) and of the left connection part (272) associated with the vacuum carriage plate (25). By means of the vacuum pads (22) placed to the lower surface (274) of the right connection part (271 ) and of the left connection part (272), the sheet parts, which have long dimensions and which have narrow widths and which are in flat form, are transferred to the bending area. Thanks to the vacuum pads (22) placed to the front surface (273) of the right connection part (271 ) and of the left connection part (272), the sheet part can be carried from the part which is bent 90 degrees. In case the vacuum mechanism (20) passes to the park position (I), the stop drive element (42) provided at the stop mechanism (40) releases the lower locking element (23) provided at the vacuum mechanism (20), and the association of the lower locking element (23) to the compression element (43), provided at the stop mechanism (40), is broken. In order to provide locking of the vacuum mechanism (20) on the movable surface (12), at least one safety element (18), provided on the movable surface (12), and at least one lock element (17), associated with said safety element (18), are associated with the vacuum mechanism (20). Thus, the vacuum mechanism (20) is fixed onto the movement surface (12). Afterwards, the guide (14), which moves in the guide bearing (15), is moved by the drive element (13) and provides the vacuum mechanism (20) to pass to the park position (I).
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.
