Data relating to the operation state is output to the control device 20.

Next, the operation of the casting apparatus 1 for casting molding, particularly the operation of setting the casting molding mold 14 after picking up the partition plate 7 will be described.
FIG. 7 is a flowchart illustrating an example of control.
In the partition plate setting device 8, first, the arm 10 is moved up to the partition plate delivery device 2 (S100), and the arm 10 is started to descend and the floating process is executed (S102, S104). Then, it is determined whether or not the floating process has been completed (S106). Whether or not the floating process has ended is determined by reading the value of the flag F. That is, if the flag F has a value of 0, the floating process has not been processed, and if the flag F has a value of 1, the floating process ends.

When it is determined that the floating process has been completed, the partition plate 7 is picked up (S108), the flag F is reset to 0 (S110), and the arm 10 is raised and moved onto the casting mold 14. (S112, S114).
Thereafter, the arm 10 starts to descend, and the floating process is executed to determine whether or not the floating process is completed (S116 to S120). If it is determined in step S106 or S120 that the floating process has not been completed, the floating process is repeatedly executed until the floating process is completed.

When it is determined that the floating process in step S118 has been completed, a process for determining the state of the partition plate 7 is performed (S122, S124). This process can be determined by the presence or absence of a signal from the touch sensor 27. The touch sensor 27 is configured to transmit a signal when not in contact with the partition plate 7 and not transmit a signal when in contact with the partition plate 7. Therefore, if there is a signal from the touch sensor 27, it is determined that the partition plate 7 is not in contact with any of the six touch sensors 27, that is, not horizontal, and if there is no signal, the partition plate 7 has six touches. It is determined that the sensor 27 is in contact with all of the sensors 27, that is, horizontal.
When it is determined that all the partition plates 7 are horizontal, the partition plate 7 is set on the mold 14 (S126), and when it is determined that the partition plates 7 are not horizontal, the arm 10 is moved to a collection unit (not shown) (S128). The partition plate 7 is collected by the collection unit (S130). Then, the flag F is reset to 0 (S132), the arm 10 is moved to the original position (S134), and the partition plate setting process is terminated.

Next, the floating process of the partition plate setting device 8 will be described.
In the floating process, as shown in the flowchart of FIG. 8, the stroke sensors S1 and S2 and the flag F are read (S200), and a process of determining whether or not the value of the flag F is 0 is executed (S202). Here, the flag F is set to determine whether or not the floating processing state has ended. If the value is 0, the processing is not processed, and if the value is 1, the processing is ended. When it is determined that the flag F is 0, it is determined whether or not the stroke sensor S1 is turned on (S204).
When it is determined that the stroke sensor S1 is turned on, the swinging portion 11b of the floating portion 11 is brought into a free state with respect to the fixed portion 11a (S206). Here, the state control of the floating part 11 is performed depending on whether the air supplied to the floating part 11 is supplied through the R6 or exhausted, and is in a locked state when air is supplied and in a free state when air is exhausted.

Subsequently, it is determined whether or not the stroke sensor S2 is turned on (S208). When it is determined that the stroke sensor S2 is ON, the floating unit 11 is locked (S210), the flag F is set to a value 1 (S212), and the present floating process is terminated.
Note that the stroke sensors S1 and S2 are constituted by proximity switches, for example.

As shown in FIG. 5, the stroke sensor S1 is turned on in a state where the positioning pin 28 is slightly inserted into the positioning hole 30, and when the stroke sensor S1 is turned on, the floating portion 11 is set as described above. Controlled to be free.
Thereby, the position shift with the arm 10 and the preparation position of the partition plate sending apparatus 2, or the metal mold | die 14 can be absorbed.
Next, as shown in FIG. 6, when the positioning pin 28 is completely inserted into the positioning hole 30, the stroke sensor S2 is turned on, and when the stroke sensor S2 is turned on, the floating portion 11 is as described above. Controlled to be locked.
Thereby, the positional relationship between the arm 10 and the preparation position of the partition plate feeding device 2 or the mold 14 can be maintained in an appropriate state, and positional deviation can be prevented.

Further, the control device 20 is provided with a display screen 21 and a plurality of selection buttons 22, 22, 22 for each engine type.
The control device 20 is connected to the partition plate delivery device 2 via a signal line R1, and based on a signal from the control device 20, the four pushers 4, 4, 4, 4 of the partition plate delivery device 2 are connected. The pitch interval and the like can be adjusted.
That is, the partition plate delivery device 2 is configured to adjust the pitch interval of the four partition plates 7, 7, 7, 7 that are sent out and positioned by a command from the control device 20.
Further, the pitch interval state of the four partition plates 7, 7, 7, 7 in the partition plate delivery device 2 is fed back to the control device 20 via the signal line R 1.

Each frame portion 6 of the partition plate feeding device 2 is provided with an upper sensor 24 and a lower sensor 25 spaced apart from each other in the vertical direction. These sensors are constituted by proximity sensors. A signal from the lower sensor 25 is configured to be input to the control device 20 via the signal line R2.
That is, for example, when the remaining amount of the partition plates 7 stacked in the frame portion 6 becomes about 50, the upper sensor 24 detects this, and the control device 20 detects the partition plate 7 in the frame portion 6. Can be warned to replenish.
Further, when the lower sensor 25 detects that the remaining amount of the partition plate 7 in the frame portion 6 is about 10, the partition plate feeding device 2 can be stopped via the control device 20.

The control device 20 and the ECU 29 of the partition plate setting device 8 are connected via a signal line R3, and the four suction cups 13, 13, 13 of the partition plate setting device 8 are connected by a signal from the control device 20. , 13 can be adjusted, and this adjustment state is fed back.
Further, the control device 20 is configured such that a detection signal from a temperature sensor 23 provided on the lower mold 14a of the cast-in mold 14 is input via a signal line R4.

The plurality of selection buttons 22, 22, 22 of the control device 20 are buttons distributed for each type of engine, and for each type of engine, that is, for each type of the intake passage core 18 to be manufactured. It is provided and any one of the selection buttons 22 can be selected and turned on.
In addition, in the control device 20, for each engine type, the pitch interval of the partition plates 7 and 7, the dimension of the partition plate 7, the material of the partition plate 7, the material of the mold 14 for casting molding, etc. Data necessary for thermal expansion calculation is stored in advance.
Further, the display screen 21 of the control device 20 is configured to display information on products related to manufacturing, such as an engine model name, an error message, and the like.

  In addition, since the size, material, etc. of the cast-in mold 14 or the partition plate 7 are different for each type of engine, when manufacturing the intake passage core 18 corresponding to the type of engine, When the operator turns on one of the selection buttons 22 corresponding to the engine type, the control device 20 inputs a temperature signal from a temperature sensor 23 provided in the casting mold 14, Based on this, the thermal expansion amount of the casting mold 14 and the thermal expansion amount of the partition plate 7 are calculated in the control device 20 as shown in the flowchart of FIG.

A signal from the control device 20 based on the calculated value indicates a pitch interval between the pushers 4, 4 and 4 of the partition plate feeding device 2 and a pitch interval between the four suction cups 13 and 13 of the partition plate setting device 8. Is controlled so as to coincide with the pitch interval of the four set grooves 16, 16, 16, 16 of the cast mold 14 for thermal expansion.
Therefore, in the partition plate feeding device 2, the four partition plates 7, 7, 7 are arranged at a pitch interval corresponding to the pitch interval of the four set concave grooves 16, 16, 16, 16 of the casting mold 14. , 7 can be sent out and positioned, and the partition plate setting device 8 can hold the pitch interval and pick up the four partition plates 7, 7, 7, 7 for good casting molding. The four set grooves 16, 16, 16, 16 of the mold 14 can be reliably set, and the partition plate 7 is reliably set horizontally in each set groove 16.

  In the cast-in-case casting apparatus of the embodiment, when the partition plate 7 is in a horizontal state, all of the six touch sensors 27 are contacted, and when the partition plate 7 is not in a horizontal state, any of the six touch sensors 27 is contacted. However, when the partition plate 7 is in the horizontal state, it does not come into contact with any of the six touch sensors 27, and when the partition plate 7 is not in the horizontal state, it makes contact with any of the six touch sensors 27. It is good as a thing.

Further, in the casting apparatus for cast-in-molding of the embodiment, the touch sensor 27 transmits a signal when not in contact with the partition plate 7 and does not transmit a signal when in contact with the partition plate 7. However, conversely, the signal may not be transmitted when the touch sensor 27 is not in contact with the partition plate 7 and may be transmitted when the touch sensor 27 is in contact with the partition plate 7.
In this case, the process of determining the state of the partition plate 7 is determined to be determined to be horizontal if there is a signal from the touch sensor 27, and determined to be not horizontal if there is no signal. It ’s fine. Alternatively, the first signal may be transmitted when the touch sensor 27 is not in contact with the partition plate 7, and the second signal may be transmitted when the touch sensor 27 is in contact with the partition plate 7. In this case, if there is a first signal, it is determined that the partition plate 7 is not horizontal, and if there is a second signal, it is determined that the partition plate 7 is horizontal.

  Moreover, in the casting apparatus for cast case forming of the embodiment, the partition plate setting device electronic control unit 29 is provided separately from the control device 20, but the control device 20 corresponds to the partition plate setting device electronic control unit 29. It is good also as what has a control part to perform.

The difference can be calculated by multiplying the difference of 270 ° C. by the coefficient of thermal expansion of the cast-in mold, and the extension due to the thermal expansion is about 1 mm.
Thus, the pitch intervals of the set concave grooves 16, 16, 16, 16 of the casting mold 14 are extended by thermal expansion, and the four partition plates 7, 7 positioned by the partition plate feeding device 2 are used. , 7, and 7 with respect to the pitch interval, the pitch at which the four partition plates 7, 7, 7, 7 are positioned in advance in the partition plate feeder 2 based on the calculated value. The interval can be set to a pitch interval corresponding to the extension amount of the cast-in mold 14.

  That is, in the partition plate feeding device 2, the operator can set the pitch interval of the pushers 4, 4, 4, 4, etc. in advance in consideration of the thermal expansion amount of the casting mold 14, and the thermally expanded casting Corresponding to the pitch interval of the four set concave grooves 16, 16, 16, 16 of the molding die 14, the pitch interval of the partition plates 7, 7, 7, 7 sent from the partition plate delivery device 2 in advance is set.
