[Embodiment]
(Description of press equipment)
FIG. 1 is a schematic view of a press apparatus S of, for example, an integrated straight side frame type or a C frame type. In FIG. 1, the up-down direction, the left-right direction, and the front-back direction are also indicated by double arrows. The press device S will be described with reference to FIG. The press device S includes a drive motor 4 as a drive unit, a transmission mechanism 6, a crankshaft 8, a connecting rod 10, and a slide 12, inside and outside the housing 2. The press device S has a controller 14, a storage unit 15, a display unit 16, and an input unit 18.

  The drive motor 4 is, for example, a servo motor that is servo-controlled, and moves the mold 3 described later up and down via the transmission mechanism 6, the crankshaft 8, and the connecting rod 10 while controlling the amount and direction of rotation. The transmission mechanism 6 includes a transmission member such as a gear or a belt, and transmits the rotation of the motor shaft of the drive motor 4 to the crankshaft 8. A control signal to the drive motor 4 is sent from the controller 14.

  The crankshaft 8 and the connecting rod 10 convert the rotational movement of the motor shaft transmitted by the transmission mechanism 6 into a reciprocating movement (in this embodiment, a vertical movement). The rotation of the motor shaft rotates the crankshaft 8, and the rotation is transmitted to a connecting rod 10 having one end connected to the crankshaft 8, so that the connecting rod 10 moves up and down (moves up and down).

  A slide 12 is connected near the other end of the connecting rod 10. The slide 12 moves up and down along the gib 26 as the connecting rod 10 moves up and down. In the press device S, a bolster 22 is arranged so as to face the slide 12. An upper mold 3a as a part of the mold 3 is mounted on a surface (a lower surface in this embodiment) of the slide 12 facing the bolster 22. As a part of the mold 3, a lower mold 3 b paired with the upper mold 3 a is mounted on a surface of the bolster 22 facing the slide 12 (the upper surface in this embodiment).

  A work W as an object to be processed is arranged between the upper die 3a and the lower die 3b, and pressed by the upper die 3a and the lower die 3b, so that the press device S presses the work W. Specifically, the drive motor 4 rotates under the control of the controller 14. The rotation of the drive motor 4 is transmitted to the connecting rod 10 via the transmission mechanism 6 and the crankshaft 8, and the slide 12 moves up and down. Due to the downward movement of the slide 12, the upper die 3a is pressed by the lower die 3b, and the work W is pressed. That is, in the press apparatus S, the drive motor 4, the transmission mechanism 6, the crankshaft 8, the connecting rod 10, and the slide 12 constitute a press section. The transmission mechanism 6 is provided with a rotary encoder 25 which is a rotation speed detecting means for detecting the rotation speed of the crankshaft 8. Note that the rotary encoder 25 may be provided on a rotation shaft of the drive motor 4.

  The controller 14 controls the press device S according to various programs stored in the storage unit 15. The display unit 16 displays data indicating the state of the press device S. The input unit 18 is used to input data necessary for operating the press device S.

  Further, the press device S includes an induction motor 20 (see FIG. 2) for adjusting the length of the connecting rod 10 in order to adjust the height of the slide 12 when the crankshaft 8 is at the bottom dead center. I have. Further, the press device S includes a drive control unit 19 (see FIG. 2) such as a servo amplifier for controlling the drive motor 4 in accordance with an instruction from the controller 14.

(Block diagram of press machine, program configuration)
FIG. 2A is a block diagram of the press device S. The same components as those described in FIG. 1 are denoted by the same reference numerals. The controller 14 reads a program stored in the storage unit 15 and controls, for example, the induction motor 20 and the drive motor 4 according to the read program.

  FIG. 2B is a schematic diagram illustrating a configuration of a predetermined program (hereinafter, referred to as program No. 001) stored in the storage unit 15, for example. Conventionally, a production-motion program and a mold-exchange program have been independently prepared for one mold. This embodiment is characterized in that one program including two motion data is prepared for one mold. Here, the motion refers to an operation of the slide 12 during a machining operation or a mold changing operation, and defines the operation of the slide 12 by, for example, designating a position or a speed of the slide 12. The two motions are a motion that defines the operation of the slide 12 when processing the workpiece W (hereinafter, referred to as a production motion) and a motion that defines the operation of the slide 12 when the mold 3 is replaced. Hereinafter, it is referred to as a mold changing motion). Further, the data for motion is data for defining the operation of the slide 12, for example, data of the position and speed of the slide 12. The controller 14 generates a table for controlling the operation of the slide 12 during the machining operation or the die changing operation based on the motion data in the program.

  As shown in FIG. The data 001 is configured as follows. Program No. 001 contains the program No. When the work W is processed in accordance with 001, the name abc of the part produced from the work W and the mold name XYZ corresponding to the program on a one-to-one basis are included.

  Program No. 001 includes the value x [mm] of the die height position. Here, the die height refers to the height of the slide 12 when the crankshaft 8 is located at the bottom dead center, and a value of the die height position is set for each mold 3. Program No. 001 includes the production number N of the parts. The controller 14 has, for example, a counter (not shown), and resets the counter when the mold 3 is replaced to count up the number n (n ≧ 0) of parts to be produced. Thus, the controller 14 manages the number n of parts produced. The controller 14 determines that the production number n of the component managed by the counter is equal to the program number. If the number of products N included in 001 has been reached (n = N), it is determined that it is time to replace the currently used mold with the mold 3 for performing the next processing. Program No. 001 includes data of the production motion and data of the die exchange motion.

(Production motion)
FIG. 3A is a diagram illustrating an example of a production motion. (I) is a diagram showing the movement of the crankshaft 8, and (ii) is a graph showing the position [mm] of the slide 12 on the vertical axis and the time [sec] on the horizontal axis. The data of the production motion includes, for example, the starting position (for example, 100 mm) of the slide 12, the descending speed, the position of the lowest point of the slide 12, the number of times the same operation is repeated, the ascending speed, and the like. Further, in the production motion, the slide 12 returns from the starting position to the starting position again. In (i), the crankshaft 8 rotates past the bottom dead center and returns to the starting position. However, the crankshaft 8 may return to the starting position without exceeding the bottom dead center in accordance with the processing operation on the workpiece W. .

  The controller 14 stores the program No. Based on the production motion data 001, a table for controlling the operation of the slide 12 during the processing operation is generated, and the generated table (hereinafter, referred to as a table for production motion) is stored in the storage unit 15. The starting position of the slide 12 is stored at the head of the production motion table.

(Mold changing motion)
FIG. 3B is a diagram illustrating an example of a mold changing motion. (I) and (ii) are diagrams and graphs similar to FIG. 3 (a). The data of the mold exchanging motion includes, for example, a starting position (for example, 100 mm) of the slide 12, a descending speed, a position of the slide 12 when the mold 3 is removed or attached (hereinafter, also referred to as a setup position), an ascending speed, and the like. Including. Further, in the die changing motion, the slide 12 returns from the starting position to the starting position again. In (i), the crankshaft 8 returns to the starting position without exceeding the bottom dead center. However, the crankshaft 8 may rotate past the bottom dead center and return to the starting position.

  The controller 14 stores the program No. A table for controlling the operation of the slide 12 during the mold changing operation is generated based on the mold changing motion data of 001, and the generated table (hereinafter, referred to as a table for the mold changing motion) is stored in the storage unit. 15 is stored. The starting position of the slide 12 is stored at the head of the table for the die changing motion. When storing the table for the die changing motion in the storage unit 15, the controller 14 stores the table in a different area from the area for storing the table for the production motion.

  As described above, the controller 14 stores the table for the production motion and the table for the die changing motion in different areas of the storage unit 15. Further, the controller 14 points to the first area of the area where the production motion table is stored in the storage unit 15 when starting the machining operation, and the die of the storage unit 15 when starting the die changing operation. Point to the first area of the area where the exchange motion table is stored. For example, a start position (for example, 100 mm) of the slide 12 is stored in a leading region of each region.

  Here, the present embodiment is characterized in that the starting position of the slide 12 in the production motion coincides with the starting position of the slide 12 in the die changing motion (for example, 100 mm). The coincidence of the starting position of the slide 12 in the two motions facilitates the mutual switching between the production motion and the mold changing motion.

  As described above, in the present embodiment, one program corresponds to one mold 3, and production motion data and mold exchange for generating a production motion table in one program. Die exchange motion data for generating a motion table is included. This makes it possible to individually set the data of the production motion and the mold exchanging motion for each program. Further, when reading the program, the controller 14 can collectively receive the data of the production motion and the data of the die changing motion.

The mold exchanging method of the mold press device of the present embodiment can be applied to the case where the mold 3 is exchanged automatically and the case where the mold 3 is exchanged manually.

(When mold exchange is performed automatically)
FIG. 4 is a flowchart showing a process when the mold 3 is automatically replaced. When a predetermined condition is satisfied, the controller 14 executes the processing of step (hereinafter, referred to as S) 401 and subsequent steps. Here, the case where the predetermined condition is satisfied is, for example, a case where an instruction to start processing into the work W is received via the input unit 18, but the case where the mold 3 is not installed in the press device S, Referring to a counter (not shown) for managing the number of productions n, the number of productions n is determined by the program number. This is the case where it is determined that the number of products N included in 001 has been reached.

  Note that, when an instruction to start processing the work W is received via the input unit 18 but the die 3 is not installed in the press device S, the controller 14 determines that the die 3 is to be carried in. . The production number n is the program No. When it is determined that the number of products N included in 001 has been reached, the controller 14 determines that the mold 3 is to be carried out.

  In S401, the controller 14 determines whether to carry out the mold 3 or not. If the controller 14 determines in S401 that the mold 3 is to be unloaded, the process proceeds to S403. If the controller 14 determines that the mold 3 is not unloaded, the process proceeds to S415. In S403, the controller 14 reads from the storage unit 15 a table for a die changing motion of the die 3 (hereinafter, referred to as a die 3A) currently installed in the press device S. Here, when the mold 3A is carried in, the controller 14 reads a program corresponding to the mold 3A from the storage unit 15, and generates and stores a table for a machining motion and a table for a mold exchange motion, respectively. It is assumed that it is stored in the unit 15.

I have.

  The upper die 3a has a concave portion 3a2 on the surface facing the lower die 3b. The lower mold 3b has a protrusion 3b2 on the surface side facing the upper mold 3a. When the slide 12 moves to the setup position, the upper mold 3a and the lower mold 3b move in the left-right direction and the front-rear direction by moving while the protrusion 3b2 of the lower mold 3b fits inside the recess 3a2 of the upper mold 3a. In this way, it can be prevented from shifting in the vertical direction, and the function of a guide for vertical movement can be exhibited.

  Returning to the description of the flowchart of FIG. In S409, the controller 14 moves the slide 12 to the starting position according to the table for the die changing motion.

For example, the bogie 71 has a chain or the like (not shown) that rotates in conjunction with the die lifter 73, and the die 3 is operated while the chain is fitted to the hook 63, so that the die 3 is pressed by the pressing device S. And the carriage 71. Note that the bolster 22 has a positioning portion 65, and the positioning portion 65 positions the mold 3 loaded from the carriage 71 on the bolster 22 at the time of loading work of the die 3 described later. When the unloading of the mold 3A is completed, the bogie 71 is retracted from the position on the rear side of the press device S, and the bogie 71 on which the die 3 (hereinafter, referred to as the die 3B) used for the next processing is mounted. Moves to a position on the rear side of the press device S. Thereby, the mold 3B can be inserted. The movement of the carriage 71 can also be performed automatically. The movement of the carriage 71 may be manually performed.

  Returning to the description of the flowchart of FIG. In S415, the controller 14 determines whether to carry in the mold 3 or not. If the controller 14 determines in S415 that the mold 3 is to be carried in, the process proceeds to S417. If the controller 14 determines that the mold 3 is not carried in, the process proceeds to S439.

  In S417, the controller 14 reads a program corresponding to the die 3B (next die) to be installed in the press device S from the storage unit 15 (reading step). In the present embodiment, the controller 14 reads one program from one mold 3 once. In step S419, the controller 14 generates a production motion table based on the production motion data included in the read program (first table generation step), and stores the table in the storage unit 15.
