Description

[Detailed description of the invention] [Industrial part of Igawa! l! FJ TECHNICAL FIELD The present invention relates to a method for taking out a workpiece from a die-casting machine, which allows a workpiece molded by a die-casting machine to be taken out efficiently and connected to the next process, and an apparatus used in this method.

[Conventional technology 1] Conventionally, in a device for taking out a workpiece molded by a die-casting machine, the length of the arm used to chuck the workpiece is long, so it is difficult to chuck the workpiece accurately or to accurately place the workpiece in a predetermined position. It was difficult to set.

In this way, when the arm used to chuck the workpiece is long, it takes up a large amount of space, causing a serious problem.

Furthermore, when the arm is long and its operating range is wide, it is likely to pose a danger to the worker.

[Problems to be Solved by the Invention] Therefore, the present invention solves the deficiency 3 of the conventional Ik technique: J. By shortening the length of the arm that takes out the workpiece in the die-casting machine, and rotating the arm, the workpiece can be chucked quickly and accurately using the f and f fingers provided on the arm. The object of the present invention is to develop a method for taking out a workpiece in a die-casting machine and a device used in this method, which can be taken out without posing a danger to workers.

[Means for Solving the Problems] In order to achieve the object L, the first invention of the present invention chucks a workpiece with a finger portion provided with an angle τ1 at one end of the arm, and then chucks the workpiece with a finger portion provided at one end of the arm. further, the sleeve is rotated 180 degrees and the arm is also rotated 180 degrees, and then the arm is slid in the sleeve in the opposite direction to move the workpiece, Furthermore, there is a method for taking out a workpiece in a die-casting machine by releasing the above-mentioned chucking of the finger part, and the second invention includes an arm having an end attached with a finger part for chucking the workpiece, and a slidable part of the arm. A sleeve for holding, a holding means serving as an actuator for rotating the sleeve by 180 degrees, a frame to support the holding means, an actuator disposed on the sleeve, and one end fixed to the actuator. , a first connecting rod that rotates 90 degrees about the one end as a center of rotation, one end of which is rotatably connected to the other end of the first connecting rod, and the other end of which rotates to the other end of the arm. This is an apparatus used in the method of the first invention, comprising a second connecting rod that is movably fixed.

[Function 1] In the present invention configured as described above, the finger portion disposed at one end of the arm that slides and projects from the frame chucks the workpiece, and then moves this arm toward the opposite side of the projecting side. Slide the other end into the sleeve.

At this time, the first connecting rod is rotated 90 degrees by a 90 degree actuator disposed on the sleeve, and then the rotational movement is converted into a linear movement via the second connecting rod, and the arm is moved as described above. It slides into the water.

Further, the arm is rotated approximately 180 degrees by a holding means that also serves as an actuator, the positions of the one end and the other end of the arm are reversed, and then the arm is rotated 90 degrees in the direction of the one end by a reversing operation of the actuator. The workpiece is moved by sliding, and finally the chucking of the finger portion is released and the workpiece can be taken out.

[Example] In order to further clarify the gist of the present invention, examples will be described below with reference to the drawings.

In the take-out device shown in FIG. 1, a holding f stage 2, which also serves as an actuator, is fixed to a frame l provided with a tieper 11. Further, the holding stage 2 is also an actuator that can hold the sleeve 3 and rotate the sleeve 3 by 180 degrees about the rotation center 3l as required.

Next, the arm 4 serves as an arm for the take-out device, and is held by the sleeve 3 on the sliding flower, with one end 4l
A finger portion 5 is attached to the holder.

Note that here, the sleeve 3 and the arm 4 are formed by a linear way.

Next, a 90 degree actuator 6 is attached to the outside of the sleeve 3, and one end 7l of the first connecting rod 7 is fixed to this 90 degree actuator 6 so as to rotate.

Further, a second connecting rod 8 is attached to the other end 72 of the first connecting rod 7.
One end 8l of the second connecting rod 8 is rotatably connected, and the other end 82 of the second connecting rod 8 is rotatably disposed on the other end 42 side of the arm 4.

With the above configuration, a workpiece 9 formed by a die-casting machine (not shown) is chucked by the finger portion 5 as shown in FIG.

Next, the 90 degree actuator 6 is actuated to rotate the first connecting rod 7 by 90 degrees, converting this rotational movement into a linear movement via the second connecting rod 8, and moving the arm 4 to the other end 42. the inside of the sleeve 3 in the direction shown in FIG. The state after the arm 4 has thus slid toward the outside of the die-casting machine is as shown in FIG. 2.

Next, ten stages of holding 2, which also serves as an actuator, are used to hold 1
When the sleeve 3 is rotated 180 degrees about the 1n rotation center 3l, the state shown in FIG. 3 is obtained.

Next, when the 90-degree actuator 6 is operated and the first connecting rod 7 is reversed by 90 degrees, the arm 4 slides in the direction of one end 41 of the arm 4, as shown in FIG. If the position of the work 9 at this time is set as the setting position of the trimming press, for example, in the next process, the chucking of the finger part 5 is released in this state and the work 9 is trimmed. It can be set on a press.

Next, by retracing the above seven operations, the arm 4 is returned to its initial state, and the next workpiece 9 can be taken out. Moreover, all of these operations can be performed automatically.

Further, when chucking the workpiece 9 and taking it out from the die-casting machine, and releasing the chucking of the workpiece 9, the holding f stage 2, which also serves as an actuator, is reversed by 90 degrees.
It is also possible to release the chucking with the work 9 facing downward.

The above-described workpiece take-out device can be attached to the die-casting machine body or the trimming press.

Furthermore, in the operation of the above-mentioned workpiece take-out device, the third
The locking of the workpiece 9 may be canceled in the state shown in the figure.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and the specific formation, structure, combination, and operation of each part are in accordance with the above-mentioned object, operation, and invention described later. It goes without saying that these changes may be arbitrarily determined within the range in which the effects can be achieved, and none of these changes change the gist of the present invention.

[Advantageous Effects of the Invention 1] As explained in detail above, the workpiece retrieval method and device of the present invention includes sliding of an arm provided with a finger portion at one end within a sleeve and rotation of the arm by 180 degrees by rotating the sleeve by 80 degrees. Since it is combined with degree rotation, the length of the arm of the take-out device can be shortened, which allows the workpiece to be taken out quickly and accurately, and the trimming press can be used for the next L length. It can be set accurately on the Golden Saint. Moreover, it is therefore possible to improve the accuracy of trimming.

In addition, as mentioned above, since the length of the arm is shortened, the entire device becomes compact and the number of movable parts is minimized, reducing the danger to the operator. It is excellent.
