  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  Please refer to FIG. 1 and FIG. An application example of the die management system KKS to a bending machine (for example, press brake) 1 will be described. That is, the mold management system KKS includes the bending machine 1.

  FIG. 1 shows a bending machine 1. Since the bending machine 1 is already well known, only the outline will be described.

  The bending machine 1 includes an upper table 2 and a lower table 3. A punch holder 4 is provided below the upper table 2, and a die holder 5 is provided below the lower table 3. Further, a plurality of punches P are installed in the punch holder 4, and a plurality of dies D are installed in the die holder 5. On the other hand, a side frame 6 and a side frame 7 are provided on both the left and right sides of the bending machine 1 (both left and right sides with respect to the paper surface). The bending machine 1 configured as described above positions the workpiece W against the abutting portion T, and bending is performed by cooperation of the punch P and the die D.

  The bending machine 1 of the mold management system KKS includes a mold storage device 8 that stores and supplies the punch P and the die D. Then, the punch P and die D stored in the die storage device 8 based on the program layout for laying out the die in accordance with a command based on the program are specified by the punch side layout units 11 and 12 and the die side layout units 13 and 14. It is transported and arranged in the designated place. In this example, the term “layout unit” includes the case of only the punch side layout units 11 and 12, or the case of only the die side layout units 13 and 14, and further includes the case of the punch side layout units 11 and 12 and the die side layout. This includes the case of referring to both units 13 and 14.

  On the other hand, as shown in FIG. 2, the punch-side layout units 11 and 12 and the die-side layout units 13 and 14 are movable on the corresponding rails 9 and 10 in the UR axis and VR axis directions and can be positioned. (For example, control by a servo motor). Of the punch side layout units 11 and 12, the punch side layout unit 11 is provided with a photoelectric sensor 11a, and of the die side layout units 13 and 14, the die side layout unit 13 is provided with a photoelectric sensor 13a.

  The photoelectric sensors 11a and 13a emit "light" from a light projecting unit, detect light reflected by a detection body with a light receiving unit, and recognize an object from a change in the amount of light.

  The bending machine 1 has a control unit 1A. The control unit 1A is composed of a computer, and is a central processing unit such as a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), a storage unit, a display unit for displaying images, characters, and the like. And an input unit for inputting and outputting data.

  Specifically, in the mold management system KKS that manages the mold of the bending machine 1, the control unit 1A determines whether or not the mold detected by the detection unit (photoelectric sensor or the like) is an automatically laid-out mold. It functions as a determination means for determining whether or not. Then, the control unit 1A performs control to share the automatically laid-out mold and the mold mounted other than the automatic layout.

  Further, the determination means can perform a check before executing the automatic layout of the mold. On the other hand, the control unit 1A functions as a processing unit that executes a predetermined process in accordance with the determination result of the determination unit. For example, the processing means notifies the display unit or the like with a user interface when the determining means determines that there is a manually arranged mold.

  The recognition method of the metal mold | die arranged in FIGS. 3-6 is shown. Photoelectric sensors 11a and 13a are attached to the punch-side layout unit 11 and the die-side layout unit 13 of the automatic mold layout apparatus, respectively. After the program layout of the mold, whether the operator newly added a mold The sensors 11a and 13a recognize the molds arranged and check whether there is a mold other than the molds arranged in the program layout.

  The photoelectric sensors 11a and 13a move along the UR axis and the VR axis, respectively, and the position coordinates and the program layout of the photoelectric sensor 11a or the photoelectric sensor 13a are “ON (when there is a mold)”. If the photoelectric sensor is turned “ON” at a location other than the position coordinates where the program layout is performed, the operator determines that there is a new mold and adds it outside the program layout. If there is a mold that has been selected, a notification is made that there is a mold other than the HMI (Human Machine Interface) program layout. The user interface is an interface for exchanging information between a machine, particularly a computer and a user (usually a human) of the machine.

  This will be described in detail. The recognition of the punch P will be described with reference to FIGS. As shown in FIG. 3, in the die management method for managing the punch P of the bending machine 1, the punch P is automatically laid out based on a program command.

It is determined whether or not punches P1, P2, P3,... PX detected by the photoelectric sensor 11a are automatically laid out. That is, the photoelectric sensor 11a sequentially detects the punches P1, P2, P3,... PX by moving the UR axis, compares the detected position coordinates with the detected position coordinates, and determines the position. If the coordinates are different, they are identified and shared with punches PX mounted other than the automatic layout. Here, “sharing” refers to a technique including associating automatically laid punches P1, P2, P3... With manually arranged punches PX to enable use of a combination. For example, the position coordinates of the manually placed punch PX and the identification information of the punch PX are associated and stored, and the mold itself can be automatically stored in the mold storage device 8.

  Please refer to FIG. The control unit 1A executes a predetermined process according to the check result. That is, when the control unit 1A determines that there is a manually arranged punch PX, the user interface notifies the user.

  The recognition of the die D will be described with reference to FIGS. As shown in FIG. 5, in the die management method for managing the die D of the bending machine 1, the die D is automatically laid out based on a program command.

It is determined whether the dies D1, D2, D3... DX detected by the photoelectric sensor 13a are laid out automatically. That is, by moving the VR axis, the photoelectric sensor 13a sequentially detects the dies D1, D2, D3,... DX, compares the detected position coordinates with the detected position coordinates, and compares the detected position coordinates. If the coordinates are different, it is identified and shared with the die DX mounted other than the automatic layout. Here, sharing refers to a technique including associating automatically laid-out dies D1, D2, D3... With manually arranged dies DX, and enabling the use of a combination. For example, the position coordinates of the manually placed die DX and the identification information of the die DX are associated and stored, and the die itself can be automatically stored in the die storage device 8.

  Please refer to FIG. As a result of the check, the control unit 1A executes a predetermined process according to the result. That is, when the control unit 1A determines that there is a manually arranged die DX, the user interface notifies the user.

  Please refer to FIG. Since the mold management system KKS can distinguish between a mold that has been program-laid by the above-described method and a mold other than the program layout, it can be used in various modes. A check method used by the mold management system KKS will be described. In this example, the term “die” includes only the punch P, includes only the die D, and further includes both the punch P and the die D.

  First, in step SA01, a check is performed before executing a program layout (automatic layout) for laying out a mold in accordance with a command based on a program under the control of the control unit 1A.

  In step SA02, control unit 1A determines whether or not notification is necessary. If it is determined that notification is not necessary, the process proceeds to step SA03. If it is determined that notification is necessary, the process proceeds to step SA04.

  In step SA04, the control unit 1A notifies using an HMI (Human Machine Interface) or the like. The user interface is an interface for exchanging information between a machine, particularly a computer and a user (usually a human) of the machine.

  In step SA05, the control unit 1A performs appropriate processing. Then, the process is returned. The return includes not only the case of returning the processing but also the case of ending.

  In step SA03, the control unit 1A executes the program layout and automatically places the mold. In step SA06, the control unit 1A performs predetermined machining on the workpiece W using a mold having a program layout.

  In step SA07, the control unit 1A changes the program layout.

  In step SA08, the control unit 1A performs a check before executing the program layout.

  In step SA09, control unit 1A determines whether or not notification is necessary. If it is determined that there is no need for notification, the process proceeds to step SA10. If it is determined that notification is necessary, the process proceeds to step SA11.

  In step SA11, the control unit 1A gives notification through an HMI (Human Machine Interface) or the like. In step SA12, the control unit 1A performs appropriate processing. Then, the process is returned.

  In step SA10, the control unit 1A executes the program layout and automatically places the mold. In step SA13, the control unit 1A performs processing using a mold having a program layout.

  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.
