Description

  The present invention relates to a molded product take-out machine including a control unit that controls the movement of a moving part for taking out a molded product from a mold of the molding machine.

Conventionally, this type of molded product take-out machine has a take-out head that grips the molded product as a moving part thereof, and as shown in FIG. When the mold is opened (FIG. 5A), the take-out head 124 enters the molds 110 and 111 from the standby position, and the take-out head 124 is continuously directed toward the mold surface of the mold 111. 124 is moved to the molded product drawing position closest to the mold surface (FIG. 5B).
At this time, the ejector pin P of the mold 111 is protruded to release the molded product s from the mold surface, and the molded product s is held by the take-out head 124.
Next, the take-out head 124 holding the molded product s is retracted from the mold surface and is moved out of the molds 110 and 111 (FIG. 5C).
Thereafter, the take-out head 124 is conveyed to the molded product collection position outside the molds 110 and 111 to release the holding of the molded product s and collect the molded product, and then the take-out head 124 is moved back to the standby position again.
The molds 110 and 111 of the molding machine are closed when the takeout head 124 is retracted, and the next molding is performed (FIG. 5D).

Then, in such a take-out operation of the molded product of the take-out machine, the ejecting head 124 comes closest to the mold surface when the ejector pin P of the mold 111 is protruded and the molded product s is released from the mold surface. The operation is controlled so as to reach the molded product drawing position, thereby reducing the total removal time of the molded product s by the ejection time when the molded product s is released from the mold surface (patent) Reference 1).
JP 2000-317998 A

However, even in the above-described take-out machine, since the take-out head 124 is operated after the molds 110 and 111 of the molding machine are completely opened to move from the standby position into the molds 110 and 111, the mold 110 of the molding machine. , 111 starts mold opening, reaches the mold opening limit position, and is completely in the mold opening state (mold opening time of the mold), the take-out head 124 is kept waiting.
Therefore, even with the above-described take-out machine, it has been difficult to improve the work efficiency beyond that because the mold opening times of the molds 110 and 111 in the molding machine cannot be used for the take-out time of the molded product s.

On the other hand, even on the side of the molding machine provided with the above-described take-out machine, the mold is not used until the take-out head 124 of the take-out machine enters the molds 110 and 111 and then moves out of the molds 110 and 111. 110 and 111 are held in a mold open state and are in a standby state.
Therefore, until the molded product s is taken out from the molds 110 and 111 by the unloader (molded product take-off waiting time), the mold 110 and 111 cannot be closed and the next molding cannot be started. It was difficult to shorten the time.

  This invention is made | formed in view of the said situation, and makes it a subject to enable further shortening of the molded article extraction time in order to improve further the molded article extraction operation | work in a molded article extraction machine.

(1) A molded product take-out machine according to the present invention is a molded product take-out machine provided with a control unit that controls a movement part for taking out a molded product from a mold of the molding machine. The control unit has a take-out head for gripping the product, and the control unit moves the take-out head into the mold during the mold opening / closing operation, and moves the take-out head in the mold to follow the mold opening / closing operation. It is characterized by having a control configuration for controlling the operation (claim 1).
As a result, the take-out head can reach the molded product drawing position closest to the mold surface almost simultaneously with the mold reaching the mold opening limit position and being completely opened.

(2) The control unit may have a control configuration for controlling the operation so that the take-out head that moves following the opening / closing operation of the die does not approach within a predetermined distance from the moving die. 2).
As a result, while the takeout head is moved to follow the mold in the mold, the takeout head can be moved to follow the mold without colliding with the mold.
Accordingly, it is possible to ensure collision avoidance between the take-out head and the mold in the mold, and to move the take-out head following the mold that is performing the mold opening operation.

(3) For example, as the molded product take-out machine, a distance measuring means for measuring a distance from the moving part to the movable mold, and opening / closing of the mold based on a measurement result from the distance measuring means. What is provided with the metal processing machine which performs the process for controlling the movement of an extraction head so that the extraction head which moves according to a movement is movable, and it does not approach within predetermined intervals (Claim 3) is mentioned. .

(4) The control unit is configured to turn off the measurement by the distance measuring means and stop the processing by the arithmetic processor when the mold reaches the mold opening limit position and is completely opened. (Claim 4).
Thereby, when the mold is completely opened, the take-out head is not controlled to move even if it approaches the mold surface within a predetermined interval.
Therefore, when the mold is fully opened, the take-out head can be moved to the molded product drawing position closest to the mold surface as expected, and the molded product released from the mold surface can be reliably Can be gripped.

As described above, according to the present invention, as compared with the case where the mold is completely opened, the take-out head is operated and moved to the molded product drawing position closest to the mold surface. The total removal time of the molded product can be shortened by the mold opening time.
As a result, the production efficiency of the molded product can be further improved.

The take-out machine 2 includes an arm mechanism 20 that extends in the XYZ axial directions and a take-out head 24 that holds a molded product.
The arm mechanism 20 includes a traversing arm 21 extending in a direction orthogonal to the opening / closing direction of the molds 10, 11 of the molding machine 1 (Y direction in FIG. 1), and the opening / closing direction of the molds 10, 11 of the molding machine 1 (FIG. 1). A drawing arm 22 extending in the X direction) and a lifting arm 23 extending in the vertical direction of the molding machine 1 (Z direction in FIG. 1).
The transverse arm 21 is mounted and fixed on the stationary platen 12 of the molding machine 1.
The pull-out arm 22 is mounted on the traverse arm 21 and is moved forward and backward in a direction (Y direction in FIG. 1) perpendicular to the mold 10 and 11 opening / closing direction by a first drive source M1 (not shown) such as a servo motor. .
The lifting arm 23 is suspended from the pulling arm 22 and is moved forward and backward in the mold 10 and 11 opening / closing direction (X direction in FIG. 1) by a second drive source M2 (not shown) such as a servo motor. The molding machine 1 is moved up and down (Z direction in FIG. 1) by a third drive source M3 (not shown) such as a motor.
The take-out head 24 is attached to the lower end of the elevating arm 23, holds and takes out the molded product from the molds 10 and 11, and releases the holding at the molded product collection position outside the molding machine 1 to collect the molded product. Let
The extraction arm 22, the lifting arm 23, and the take-out head 24 constitute a moving part of the take-out machine 2.

The take-out head 24 is provided with distance measuring means 3 for measuring the distance between the molds 10 and 11 in the molds 10 and 11.
The distance measuring means 3 includes an ultrasonic sensor having a pair of sensitive parts that transmit and receive ultrasonic waves, and is installed so as to face the molded product holding surface side of the take-out head 24.

In addition, the unloader 2 is provided with a control unit 25 for controlling the operation of the unloader 2, and a touch panel controller 4 for performing operations such as starting / stopping automatic operation and teaching operation is connected with a cable. .
In addition, this controller 4 may be connected to the unloader 2 by communication in addition to cable connection.

  As shown in FIG. 2, the control unit 25 of the unloader 2 includes a drive source control unit A1, A2, A3 configured by a servo amplifier or the like that controls the operation of the drive sources M1, M2, and M3 in the arm mechanism 20, and a mold. The distance / interval setting means 26 for setting the distance between the take-out head 24 and the molds 10 and 11 during the movement of the take-out head 24 in the 10, 10 and the take-out head 24 in the molds 10 and 11 are provided. An arithmetic processor 27 that performs a predetermined process so as to hold the set value in the distance / interval setting means 26, and the drive source control units A1 to A3 and the arithmetic processor 27 are connected to control the operation of the unloader 2. And a control mechanism 28.

The control mechanism 28 of the take-out machine 2 is I / O connected to the control mechanism 18 of the molding machine 1 so that the operation of the take-out machine 2 can be controlled in synchronization with the operation of the molding machine 1.
The distance / interval setting means 26 sets a predetermined interval for keeping the distance so that the take-out head 24 does not collide with the molds 10 and 11, and can be set by an input operation from the controller 4, for example.

The arithmetic processing unit 27 is connected to the distance / interval setting means 26 and the distance measuring means 3, and compares the set value in the distance / interval setting means 26 with the measurement result from the distance measuring means 3, and takes out the head. A process for controlling the movement of the take-out head 24 is performed so that 24 does not approach the mold surface within a predetermined interval, and a command signal as a result of the process is output to the control mechanism 28.
As a result, the control mechanism 28 controls each of the drive sources M1 and M1 in the arm mechanism 20 so that the take-out head 24 does not collide with the molds 10 and 11 in the molds 10 and 11 based on the command signal from the arithmetic processor 27. M2, M3 drive source control units A1, A2, A3 (in the unloader 2 of FIG. 1, the second drive source control unit A2 of the second drive source M2 of the extraction arm 22 and the third drive source of the third drive source M3) A predetermined control command is output to the control unit A3).

Next, the operation will be described.
As a basic operation, the molding machine 1 injects and fills molten resin into the molds 10 and 11 that are closed, and opens the molds 10 and 11 at the timing when the resin is cooled and solidified. When the product is taken out, the molding operation of closing the molds 10 and 11 again is repeated.
On the other hand, as a basic operation, when the molds 10 and 11 of the molding machine 1 are opened, the take-out machine 2 moves the take-out head 24 into the molds 10 and 11 from the standby position and holds the molded product. The take-out head 24 holding the product is transported to the molded product collection position outside the molds 10 and 11 to release the hold of the molded product, collect the molded product, and then return the take-out head 24 to the standby position again. Repeat the extraction operation.

In the take-out machine 2 of the present embodiment, the take-out head 24 is operated as follows in the process of taking out the molded product from the molds 10 and 11.
3 and 4, when the molds 10 and 11 in the molding machine 1 start to open and a gap into which the takeout head 24 can enter is formed in the molds 10 and 11, this mold opening operation is performed. The take-out head 24 is caused to enter the inner molds 10 and 11 (S1 and S2 in FIG. 3: FIGS. 4A and 4B).
When the take-out head 24 enters the molds 10 and 11, the take-out head 24 is moved to follow the mold 11 on the movable platen 13 moving in the mold opening limit direction, and the distance measuring means 3 is turned on. Then, measurement of the distance from the take-out head 24 to the mold surface of the mold 11 is started (S3 and S4 in FIG. 3: FIG. 4C).
Thereby, while the extraction head 24 is made to follow the mold 11, the distance measuring means 3 always measures the distance from the extraction head 24 to the mold surface of the mold 11 moving in the mold opening limit direction.

Then, the measured value of the distance from the take-out head 24 to the mold surface of the mold 11 as the measurement result of the distance measuring means 3 is compared with the set value in the distance / interval setting means 26 (S5 in FIG. 3). Then, it is monitored whether or not the actually measured value is not less than the set value (S6 in FIG. 3), that is, whether or not the take-out head 24 following the mold is separated from the mold surface during the mold opening operation by a predetermined distance or more.
At this time, if the measured value is equal to or greater than the set value, the take-out head 24 is separated from the mold surface by a predetermined distance or more. In this case, the take-out head at the predetermined set speed based on the teaching data is used as it is. The mold following movement of 24 is continued (S7 in FIG. 3).

On the other hand, when the measured value is less than the set value, the take-out head 24 is close to the mold surface of the mold 11 within a predetermined interval. Since there is a possibility of collision, the processor 27 outputs a command signal to the control mechanism 28 so as to decelerate or temporarily stop the movement of the take-out head 24 (S8 in FIG. 3).
And the control mechanism 28 which received the command signal from the arithmetic processor 27 is a drive source control part (In the unloader 2 of FIG. 1, it is the drive source control part A2 with respect to the 2nd drive source M2 of the extraction arm 22.). A control signal for correcting the movement speed of the extraction head 24 is output, and the movement of the extraction head 24 is decelerated or temporarily stopped from the intended set speed (S9 in FIG. 3).

  Subsequently, until the mold 11 reaches the mold opening limit position, the take-out head 24 following the mold by the distance measuring means 3 and the arithmetic processor 27 is within a predetermined distance from the mold 11 during the mold opening operation. It is monitored whether or not they approach each other, and when the actual measurement value becomes equal to or larger than the set value and the take-out head 24 is separated from the die surface of the die 11 by a predetermined distance or more, the take-out head 24 is followed by the die according to a predetermined set speed. Move (S10, S4 to S7 in FIG. 3).

When the mold 11 reaches the mold opening limit position and is completely opened, the distance measurement by the distance measuring means 3 is turned off and the processing in the arithmetic processor 27 is stopped (S10 and S11 in FIG. 3).
As a result, even if the take-out head 24 approaches the mold surface of the mold 11 within a predetermined interval, the movement is not controlled by the control mechanism 28.
Therefore, when the molds 10 and 11 are completely opened, the take-out head 24 can be moved to the molded product drawing position close to the mold surface of the mold 11 as expected (S12 in FIG. 3). FIG. 4 (d)).
The arrival of the mold 11 at the mold open limit position is detected by the movable platen position detector 16 of the molding machine 1, and the detection result is sent to the control mechanism 28 of the unloader 2 through the control mechanism 18 of the molding machine 1. Is output.
Therefore, the unloader 2 can also recognize that the mold 11 has reached the mold open limit.

On the other hand, in the molding machine 1, as soon as the mold 11 reaches the mold open limit position, an ejection command for the molded product s is issued, and the ejector pin P provided in the mold 11 is ejected to eject the molded product s from the mold surface. Release.
At this time, as described above, the take-out head 24 is moved to follow the mold 11 that is performing the mold opening operation. Therefore, when the ejection of the ejector pin P is completed, that is, the molded product s is released from the mold surface. By the time, the take-out head 24 has reached the molded product drawing position closest to the mold surface of the mold 11 (see FIG. 4D).
Accordingly, the molded product s released from the mold surface of the mold 11 is securely gripped by the take-out head 24.
Then, when the take-out head 24 completes the suction of the molded product s at this molded product drawing position (S13 in FIG. 3), the take-out head 24 is moved backward in the direction away from the mold 11 and the distance measuring means. 3 is turned on and measurement of the distance from the take-out head 24 to the mold surface of the mold 11 is started (S14 and S15 in FIG. 3: FIG. 4E).

In the molding machine 1, when the housing of the ejector pins P is completed, the mold closing operation is started to perform the next molding, and the movable platen 13 is moved in the mold closing direction.
Therefore, when the take-out head 24 moves backward from the mold 11, the take-out head 24 follows the mold closing operation of the mold 11 in advance so as to be followed by the mold 11 of the movable platen 13.
Therefore, during this mold closing operation, the distance measuring means 3 always measures the distance from the take-out head 24 to the mold 11 moving in the mold closing limit direction.

Then, the measured value of the distance from the take-out head 24 to the mold surface of the mold 11 as the measurement result of the distance measuring means 3 is compared with the set value in the distance / interval setting means 26 (S16 in FIG. 3). Then, it is monitored whether or not the actually measured value is equal to or greater than the set value (S17 in FIG. 3), that is, whether or not the take-out head 24 following the mold is separated from the mold 11 during the mold closing operation by a predetermined distance or more.
At this time, if this measured value is greater than or equal to the set value, the takeout head 24 is separated from the mold 11 by a predetermined distance or more, and in this case, the takeout is performed at the desired set speed based on the teaching data. The mold following movement of the head 24 is continued (S18 in FIG. 3).

On the other hand, when the measured value is less than the set value, the take-out head 24 is close to the mold 11 within a predetermined interval. If left as it is, the take-out head 24 is overtaken by the mold 11 and the take-out head 24 is moved into the mold. Since there is a possibility of colliding with the mold 11, the processor 27 outputs a command signal to the control mechanism 28 so as to accelerate the movement of the takeout head 24 (S19 in FIG. 3).
The control mechanism 28 that has received the command signal from the arithmetic processor 27 is a drive source control unit (in the unloader 2 in FIG. 1, the drive source control unit A2 for the second drive source M2 of the extraction arm 22). In the case of performing the R operation for moving the extraction head 24 upward at the same time, a drive source control unit A3 for the third drive source M3 of the extraction arm 22 is also included.) A control signal for correcting the movement speed of the extraction head 24 is output. Then, the movement of the take-out head 24 is accelerated more than the intended set speed (S20 in FIG. 3).

  Subsequently, until the take-out head 24 moves out of the molds 10 and 11, the take-out head 24 following the mold by the distance measuring means 3 and the arithmetic processor 27 is spaced from the mold 11 during the mold closing operation by a predetermined distance. The measured value becomes equal to or greater than a set value, and when the take-out head 24 is separated from the mold 11 by a predetermined distance or more, the take-out head 24 is moved following the mold at a predetermined set speed. (S21, S15 to S18 in FIG. 3).

When the take-out head 24 moves out of the molds 10 and 11, the distance measurement by the distance measuring means 3 is turned off and the processing in the arithmetic processor 27 is stopped (S21 to S23 in FIG. 3: FIG. )).
On the other hand, in the molding machine 1, the mold 11 is actually closed simultaneously with the backward movement of the takeout head 24, so that when the takeout head 24 moves out of the molds 10 and 11, almost immediately after that. The mold 11 reaches the mold closing limit position and is completely closed.

Thereafter, in the take-out machine 2, the take-out head 24 that has been withdrawn from the molds 10 and 11 is moved to a predetermined molded product collection position to release the molded product s, and is then moved back to the standby position again. In preparation for the take-out operation (S24 in FIG. 3).
Further, in the molding machine 1, the molding process is executed by injecting and filling molten resin from the injection mechanism 15 into the molds 10 and 11 that are closed.
Thereafter, the take-out operation of the take-out machine 2 is repeatedly performed.

As described above, according to the molded product take-out machine 2 according to the present embodiment, the take-out head 24 enters the molds 10 and 11 during the mold opening operation of the molds 10 and 11, and the inside of the molds 10 and 11. Then, since the take-out head 24 is moved following the mold 11 that is performing the mold opening operation, the take-out head 24 is moved to the position of the mold 11 almost at the same time when the mold 11 reaches the mold open limit position and is completely opened. The molded product drawing position closest to the mold surface can be reached.
Therefore, compared to the case where the molds 10 and 11 are completely opened, the take-out head 24 is operated and moved to the above-mentioned molded product drawing position, the molded products s are formed for the mold opening time of the molds 10 and 11. It is possible to shorten the total take-out time.

Further, while the takeout head 24 is moved following the mold 11 in the molds 10 and 11, the movement of the takeout head 24 is controlled so that the takeout head 24 does not approach the mold 11 within a predetermined interval. Therefore, the takeout head 24 can be moved following the mold 11 without colliding with the mold 11.
Therefore, it is possible to ensure the collision of the take-out head 24 with the mold 11 in the molds 10 and 11 and to move the take-out head 24 to the mold 11 that is performing the mold opening operation.
As a result, the total removal time of the molded product can be reliably shortened, and as a result, the production efficiency of the molded product s can be reliably improved.

On the other hand, in the molding machine 1 as well, it is possible to substantially eliminate the waiting time for taking out the molded product in which the molds 10 and 11 are kept waiting until the molded product s is taken out by the take-out machine 2.
That is, the take-out head 24 enters the molds 10 and 11 during the mold opening operation of the molds 10 and 11, and the take-out head 24 moves in the molds 10 and 11 following the mold 11 that is performing the mold opening operation. Therefore, the time until the take-out head 24 enters the molds 10 and 11 and holds the molded product s, and until the take-out head 24 moves out of the molds 10 and 11 after holding the molded product s. The total time (the above-mentioned waiting time for taking out the molded product) can be used for the opening / closing operation of the molds 10 and 11.
Therefore, the total molding time of the molding machine 1 can be shortened by the waiting time for taking out the molded product.

  From the above, in addition to shortening the total take-out time of the take-out machine 2, the overall molding cycle is shortened by shortening the total molding time of the molding machine 1, so that the production efficiency of the molded product s is further improved. be able to.

  The present invention is not limited to the above-described embodiment. For example, as the distance measuring means 3, in addition to the ultrasonic sensor, various optical sensors (laser, infrared use, etc.), image pickup means, electromagnetic wave use apparatus, etc. May be used.

  In addition, depending on the specific distance measuring means 3, there is a possibility that good distance measurement may not be possible due to the state of the mold surface of the mold 11 (for example, a textured surface). Therefore, the distance measuring means before the unloader 2 is automatically operated. A test operation for confirming whether or not the ultrasonic wave, light beam, etc. in 3 can be detected satisfactorily may be performed.

Further, the position and number of the distance measuring means 3 can be appropriately set so that the distance from the take-out head 24 that has entered the molds 10 and 11 to the moving mold 11 can be measured.
For example, a plurality of distance measuring means 3 may be provided on the takeout head 24, or may be provided on the part of the pulling arm 23 that is not provided on the takeout head 24 and enters the molds 10 and 11, and In addition, it may be provided so as to measure the distance between the take-out head 24 and the mold 11 by directing the entire molds 10 and 11 at the stationary part of the molding machine 1 and the take-out machine 2.

The take-out machine 2 is not only the traverse type, but also a side entry type that takes out the molded product from the side of the mold, and a rotary type that takes out the molded product by rotating the arm. You may apply to the machine.
In addition, the molding machine 1 on which the unloader 2 is mounted may be either a vertical type or a horizontal type as long as the mold opening / closing operation is performed, and the molded product is only made of resin. Alternatively, it may be made of metal such as aluminum.
