  With reference to FIG. 1, a mold exchanging auxiliary device (mold exchanging auxiliary system) S will be described. Fig.1 (a) is a side view of a metal mold | die exchange auxiliary | assistance apparatus, FIG.1 (b) is a front view of a metal mold | die exchange auxiliary | assistance apparatus.

  In the mold exchanging auxiliary device S that assists in exchanging the mold of the bending machine 1, a bending machine control apparatus 8 (generating means) that reads predetermined information from the input device 9 (input means) and generates projection information; A plurality of projectors 10 to 13 that project projection information are provided. The projectors 10 to 13 project the shape of the mold onto the mounting position of the mold based on the projection information.

  The bending machine control device 8 comprises a computer and has a CPU to which a ROM and a RAM are connected. Further, an internal memory, an external memory (storage means) and the like are connected to the CPU.

  The bending machine 1 includes side frames 2 and 3. The side frame 2 is provided with a cylinder 4, and the side frame 3 is provided with a cylinder 5.

  On the other hand, the bending machine 1 has an upper frame 6. The side frames 2 and 3 are provided with a lower table 7L and an upper table 7U. The upper table 7U is configured to be movable up and down by the action of the cylinders 4 and 5.

  In addition, as shown in FIG.1 (b), the open height of the bending machine 1 of this embodiment is shown by OH, and the table height is shown by TH.

  The upper table 7U is provided with a plurality of punches P (P1, P2, P3), and the lower table 7L is provided with a plurality of dies D (D1, D2, D3). Are configured to bend the workpiece W.

  The plurality of projectors 10 to 13 are installed so as to project the shapes of the dies D1, D2, D3, punches P1, P2, P3, and the like onto the mold mounting position of the bending machine 1. There are a plurality of projectors 10 to 13 around the machine (bending machine 1) or around the machine, and the projectors 10 to 13 are installed so as to reduce a blind spot where an operator cannot project an image due to a shadow. In this embodiment, the first projector 10 is provided at the center below the front side of the die D and punch P, and the second and third projectors are provided on the left and right of the upper frame 6 above the front side of the die D and punch P. 11 and 12 are provided, and a fourth projector 13 is provided above the rear side of the die D and the punch P.

  Further, the projection information includes information on the die holder 14 (see FIG. 3), and the projectors 10 to 13 project the shape of the die holder 14 to a predetermined position. The projection information includes a mold ID for identifying the mold, and the projectors 10 to 13 project the mold ID.

  The control operation of the bending machine control device 8 will be described with reference to FIG.

  In step S01, predetermined information is obtained from the program data. Specifically, information related to the mold, such as mold ID (for identifying the mold), mold length, width, height, die holder length, width, height, etc. is input. Obtained from the device 9.

  In step S02, machine data (machine data of the bending machine 1) is read. Specifically, information such as the table length, the open height OP, the height TH and the width TW of the lower table is acquired.

  In step S03, the projection information on the lower table 7L is created. That is, projection information to be projected onto the lower table 7L is created from the read machine data and die information (lower die height DH, lower die width DW, thickness, etc.).

  Details of the creation of projection information in step S03 will be described below as steps S04 to S07.

  In step S04, information (width TW, length, height TH) of the lower table 7L is extracted from the read machine data.

  In step S05, what is attached (holder, mold, rail) on which position on the lower table 7L is calculated from the mold information installed on the lower table 7L, and an image is created.

  In step S06, if there is a mold to be placed on the state set above with the read mold information, an image of the placed state is created and stored as another image.

  In step S07, the same process is repeated until all the set mold information is created as an image. Thus, the projection information of the die mold D from the upper side is created.

  In step S08, the projection information from the front is created. Projection information from the front is created from the read machine data and mold information.

  Details of the creation of the projection information in step S08 will be described below as steps S09 to S11.

  In step S09, a holder, a die D, and the like to be placed on the lower table 7L are created for the lower table 7L in order from the bottom while matching the positional relationship with the table from the read mold information.

  In step S10, the upper table 7U is created while aligning the positions of the intermediate plate, the clamp device, the punch P, and the like attached to the upper table 7U.

  In step S11, projection information from the front is created by combining the images of the lower table 7L and the upper table 7U.

  In step S12, the projection information is corrected. The projection information is corrected based on the positional relationship between the machine and the projector, and projection information having a shape suitable for the actual machine is created. That is, if the image is projected as it is, it will be distorted into a trapezoid, so that the projected image is corrected from the positional relationship between the machine and the projector and projected onto the machine. Further, when there are a plurality of projection images, they can be switched by an operator.

  As described above, the mold is automatically set based on the bending conditions such as the plate thickness and the bending angle based on the information obtained by the input device 9. A projected image is created based on the set mold information, and the created image is projected so as to overlap with the actually attached mold.

  The worker attaches the mold to the machine based on the projected image. The workability is improved because it is not necessary to compare the setting screen with the mold during installation. In addition, it is easy to notice that the position is shifted or that the attached mold is different from the set mold. That is, when projected from the front, the height is also projected, so it is easy to notice that it is different from the mold set when viewed.

  In addition, it can be noticed that it is difficult to judge only by the shape by ID projection, and it can be seen that the installation position and length of the die D are wrong when projected on the lower table.

  Please refer to FIG. In this case, the arrangement position of the die D (D1, D2, D3) is projected from the upper side of the bending machine 1, the die holder 14 provided on the lower table 7L, and the die D provided on the die holder 14 (D1, D2, D3) are displayed in a switchable manner.

  Here, it can be seen from the projection of the die D that the projected image and the actual mold are different in the CK1 portion of the die D2, and the size of the die is different in the CK3 portion of the die D3. In addition, it turns out that the die | dye D1 has arrange | positioned the appropriate metal mold | die in the appropriate position.

  Please refer to FIG. In this case, the projected image of the die holder 14 is viewed from the front, and it can be seen that the height of the projected die holder and the actual die holder 14 are different as shown by the CK3 portion.

  Please refer to FIG. In this case, the arrangement positions of the die D and the punch P are projected from the front, and the die holder 14 provided on the lower table 7L and the die D (D1, D2, D3) provided on the die holder 14 are provided. In addition, punch P (P1, P2, P3) is displayed. Here, the projection image and the real thing of the CK4 portion of the die D1, the CK5 portion of the die D2, the CK6 portion of the die D3, the CK7 portion of the punch P1, the CK8 portion of the punch P2, and the CK9 portion of the punch P3 Are different as follows.

  That is, it can be seen that the CK4 portion has a different height. It can be seen that the height and width are different in the CK5 part. It can be seen that the mounting position is different at CK6. It can be seen that the CK7 part has a different height (the actual one is short). It can be seen that the CK8 part has a different height (the actual one is long). It can be seen that the mold ID is different in the CK9 portion.

  In this way, the worker can confirm without comparing the set screen with the actual one whether or not the die that he / she attached is the same as that set by the machine. Further, not only the mold length but also the mold height, mold ID and the like can be determined. Therefore, there is an effect that the same mold as the mold set by the operator can be easily attached without mistake.

  The present invention is not limited to the embodiments of the invention described above, and can be implemented in other modes by making appropriate modifications.
