Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bending mold setup operation in metal processing, and in particular, a used mold indicating apparatus in a bending apparatus capable of reliably removing a corresponding mold from a mold storage shelf and attaching it to a bending apparatus. And about the system.

  In the field of metal processing, it is common to produce a three-dimensional shape by performing bending (hereinafter referred to as bending), arc welding, resistance welding or the like on a member cut out from a steel plate such as iron. In bending work, it is common to work with a bending machine called a press brake.

  At the time of bending work by the press brake, the punch called the upper die and the die called the lower die are selected and mounted according to the material, plate thickness, length and shape to be bent.

  At this time, the worker goes to a mold storage shelf or the like that stores a plurality of molds, and selects a more appropriate mold that meets the above conditions in accordance with memories from past experiences or instructions such as drawings. . However, in general, the number of molds is often several tens to several hundreds, and the actual situation is that it takes time to select a mold.

  Conventionally, the following method is known for reducing the selection time of the mold to be used.

  The first method is to create a used mold list in advance. In the case of a product that is repeatedly produced, it is possible to reduce the time for selecting a die to be used from a drawing or the like by listing the die used at the first work and referring to the list at the next production.

  The second method is to display the mold used by adding an NC data control mechanism. In a press brake with an NC data control mechanism, a higher-level data creation department manufactures a mold to be used for the bending portion together with other press brake control data, and displays the used mold information on the operation panel. Some departments for creating upper data automatically create NC data by a program.

  Patent Document 1 discloses means for continuing processing from the beginning to the end while the mold transferred from the mold storage unit to the machine main body is attached to the machine main body side table without returning to the mold storage unit side.

  Patent Document 2 discloses means for mounting the mold in the correct position.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows an in-use mold indicating apparatus in a bending apparatus according to the present invention. Here, 1 is a bending apparatus, and includes a plurality of upper molds 8A, 8B, 8C, 8D and lower molds 9A, 9B, 9C, 9D corresponding to the upper molds 8A, 8B, 8C, 8D. The members 12 cut out from the steel plate such as iron are bent by 8B, 8C and 8D moving downward.

  Before starting the bending work in the bending apparatus 1, it is necessary to install the molds 8 and 9 in the bending apparatus 1, and the operator goes to the mold storage 2 and uses it for the intended processing work. Search for molds, carry them, and carry out installation work.

  In the present invention, the configuration of the mold storage 2 is devised to support the mold selection work. As shown in FIG. 2 as an example of the configuration of the mold storage 2, the storage location 10 is individually determined for each mold 8.9. For example, the storage place 10A is associated with the upper mold 8A and the lower mold 9A, and the storage place 10B is associated with the upper mold 8B and the lower mold 9B.

  Each mold (mold storage location) includes a mold display lamp 4 and a mold presence / absence detection sensor 11. Of the plurality of mold display lamps 4 in the mold storage 2, the mold display lamp 4 corresponding to the mold used in the bending apparatus 1 in the next work process is turned on to instruct the operator to use the mold. To do.

  The presence / absence state of the mold is detected by the mold presence / absence detection sensor 11 in the storage place 10. Therefore, if the mold presence / absence detection sensor 11 in the storage location 10 detects the absence of the mold after the mold display lamp 4 is turned on, this means that the correct mold has been carried out according to the usage instruction. doing.

  The mold display lamp 4 and the mold presence / absence detection sensor 11 of the mold storage 2 are linked to the information storage servers 5 and 6, the input device 7, the bending information display and the bending machine control device 3.

  Among these, the input device 7 is, for example, an RFID (Radio 0 Frequency Identification), and inputs information on a product to be processed next. The RFID can also be input by a barcode reader or the like. The input device 7 may be given by the operator each time, or may be given automatically from a computer or the like.

  The bending information storage server 6 stores information relating to bending when processing the product in association with the input next-processed product information. For this reason, when the next processed product information is input from the input device 7, the bending processing information for manufacturing this product is output. The bending information is delivered to the bending information display and bending machine control device 3 and the production plan storage server 5.

  In the production plan information storage server 5, for example, bending work information (production plan information) of the bending apparatus 1 is stored. In the bending work information, information at the time of the last bending work is stored.

  As a specific example, one bending apparatus 1 is provided with four sets of bending stages from the first stage to the fourth stage, and as information at the time of the last bending work, The mold 8A, the lower mold 9A, the upper mold 8B, the lower mold 9B in the second stage, the upper mold 8C, the lower mold 9C in the third stage, the upper mold 8D, the lower mold 9D in the fourth stage It is assumed that what is being used is stored in the production plan information storage server 5.

  On the other hand, the production plan information storage server 5 receives information on the next bending process from the bending process information storage server 6 as the upper mold 8F and the lower mold 9F in the first stage, the upper mold 8B and the lower mold in the second stage. Information on the use of the upper mold 8C and the lower mold 9C in the third stage, and the use of the upper mold 8G and the lower mold 9G in the fourth stage is obtained.

  The production plan information storage server 5 compares the previous and next bending information, and the upper die 8A, the lower die 9A and the upper die 8D, the lower die of the fourth stage working table. Information indicating that the mold 9D should be removed and stored in a predetermined storage location 10 of the mold storage 2 is obtained. For example, the upper mold 8A and the lower mold 9A of the first stage processing table are stored in the storage place 10A of FIG. 2, and the upper mold 8D and the lower mold 9D of the fourth stage processing table are stored in the storage place 10D of FIG. Should be kept in.

  In addition, the production plan information storage server 5 confirms that the mold presence / absence detection sensors 11A and 11D installed in the storage place 10A and the storage place 10D detect the absence of the mold. In addition, the mold display lamps 4A and 4D corresponding to the storage location 10A and the storage location 10D are sequentially turned on to guide the operator to the storage location.

  In this case, the bending information display and the information display section of the bending machine control device 3 indicate that the upper mold 8A and the lower mold 9A are removed and stored in the first stage processing table. After completion, it is displayed that the upper mold 8D and the lower mold 9D are removed and stored in the fourth stage processing table.

  When the upper mold 8A and the lower mold 9A are stored in the storage place 10A by this guide and storage, the mold presence / absence detection sensor 11A installed in the storage place 10A detects the presence of the mold. It can be removed and stored as instructed. After this confirmation, this guide and storage work for the upper mold 8D and the lower mold 9D of the fourth stage processing table are executed.

  When all removal and storage are completed in this way, a guide for taking out from the mold storage 2 and attaching to the processing table is executed.

  In this state, the molds of the first stage machining table and the fourth stage machining table are removed, and the production plan information storage server 5 first has the upper mold 8F and the lower mold 9F to be attached to the first stage machining unit. The mold presence / absence detection sensor 11F in the storage place 10F in FIG. 2 which is the storage place detects that the presence of the mold is detected. In response to the detection of the presence state, the mold display lamp 4F at the position is displayed. In accordance with this display, the operator takes out the upper mold 8F and the lower mold 9F to be attached to the first stage processing portion from the mold storage 2 and performs installation.

  In this case, the bending information display and the information display section of the bending machine control device 3 indicate that the upper mold 8F and the lower mold 9F are attached to the first stage processing table. For this reason, generally, the mold storage 2 and the bending apparatus 1 are located at separate locations, but the same operation instruction is given to the mold display lamp 4, the bending information display, and the information display section of the bending machine control apparatus 3. Since it has been released, it is possible to perform more reliable work by checking and installing it again. This is also true when stored in the mold storage 2.

  When the installation of the upper mold 8F and the lower mold 9F is completed, the operator reports the completion of the work with the input device 7. In response to this, the production plan information storage server 5 operates the bending information display and the information display section of the bending machine control device 3 and the display of the mold display lamp 4 in order to indicate the next mold installation. Match the work status at the two locations to the same display status.

  The used mold indicating apparatus in the bending apparatus of the present invention is configured as described above, thereby enabling reliable mold removal and installation work. This operation is achieved by the cooperation of the input device 7, the information storage servers 5 and 6, the bending information display and the bending machine control device 3.

In this flowchart, the processing content is displayed in the center, the bending information display on the right side and the display content on the information display unit of the bending machine control device 3, and the mold display lamp 4 and the mold presence / absence detection sensor 11 in the mold storage 2 on the left side. Is shown. This makes it clear that the work state between two distant points is synchronized.

  In processing step S1, which is the first processing in FIG. 3, information on the next processed product is input, and in processing step S2, it is converted into bending processing information corresponding thereto. The bending information is transmitted to the bending information display and the bending machine control device 3, and the 3 side recognizes the start of the next processing.

  In processing step S3, the previous and current bending process information is compared, and it is confirmed that, for example, the upper and lower molds of the first stage processing table and the fourth stage processing table should be changed. In process step S4, the number n of the machining tables is first set to 1, and the first-stage machining table is processed.

  In addition, the bending information display and the bending machine control device 3 are notified that the processing of the first stage processing table is started. The notification content includes the fact that the replacement has occurred, the processing table to be replaced is the first stage processing table, and the molds are changed from the current upper mold 8A and lower mold 9A to the upper mold 8F and the lower mold. Notify that the work is to be changed to 9F. This information is displayed on the information display section of the bending information display and bending machine control device 3.

  The worker who confirms this display confirms that the removal work of the upper mold 8A and the lower mold 9A of the first stage processing table has occurred.

  In the process step S5, the storage place 10A of the previous mold (upper mold 8A, lower mold 9A) of the processing table (first stage processing table) to be replaced is confirmed, and the mold presence / absence detection sensor 11A detects the mold. Get presence / absence detection status. At this stage, the upper mold 8A and the lower mold 9A remain installed on the first stage processing table, and the mold presence / absence detection sensor 11A detects that there is no mold.

  In process step S6, when the mold does not exist, the corresponding display lamp 4A is turned on (process step S7). The operator removes the upper mold 8A and the lower mold 9A in accordance with the display on the bending apparatus 1 side, transports them and arrives at the mold storage 2 and confirms that the display lamp 4A is turned on. By coming in the storage place 10A, it can be stored in the correct position.

  Further, if the information (mold presence / absence detection sensor 11A) indicating that the storage at the correct position has been completed is obtained in the processing step S8, and “Yes” can be confirmed in the processing step S6, it can be confirmed that the series of removal and storage has been completed. .

  The process on the installation side, which is executed subsequent to the process step S9, will be described with reference to FIG. In the state where the processing step S9 is completed, the installation of the new upper mold 8F and the lower mold 9F on the first stage machining base is completed. It is assumed that the system has recognized that the installation has been completed by an operator's report.

  When the installation is completed, in the processing step S10, the number n of machining table changes is set to n + 1, and the processing of the fourth stage machining table is started. In the processing step S11, the processing from the processing step S5 to the processing step S10 is repeated until work on all the processing tables is completed. Needless to say, when entering the process of the fourth stage machining table, the bending information display and the bending machine control device 3 are notified of entering the process of the fourth stage machining table.

  FIG. 4 is a process flowchart for correctly performing the process on the installation side. Under this premise, the operator places the mold that has been transported in the designated location of the mold storage 2 and returns to the bending apparatus 1 and then newly installs the upper mold 8F and the lower mold 9F on the first stage processing table. Trying to carry.

  In the first processing step S12 at the time of installation, the storage location 10F of the current mold (upper mold 8F, lower mold 9F) of the processing table (first stage processing table) to be replaced is confirmed, and a mold presence / absence detection sensor is detected. The presence / absence detection state of the mold in 11F is obtained. At this stage, the upper mold 8F and the lower mold 9F are in the storage place 10F, and the mold presence / absence detection sensor 11F detects the presence of the mold.

  In process step S13, when a mold exists, the corresponding display lamp 4F is turned on (process step S14). The operator removes the upper mold 8F and the lower mold 9F in accordance with the display on the mold storage 2 side, transports them, and arrives at the bending apparatus 1 side. At this time, the bending information display and the display unit of the bending machine control device 3 display that the upper mold 8F and the lower mold 9F are installed on the first stage processing table. According to this display, it can be installed at the correct position by being installed on the first stage processing table.

  Further, after the lamp is displayed, the storage location is confirmed again (processing step S15), and if “None” can be confirmed in processing step S13, it can be confirmed that the mold has been transported.

  Since it is not possible to automatically confirm that the new mold has actually been installed, it is determined that the installation has been completed with an installation work completion report from the operator. As a result, the mold can be removed, stored, and installed by one reciprocating operation of the worker, and thereafter, the correct work can be supported by sequentially executing all the worktables as shown in FIG. .
