It is driven by a step motor 70 attached to the 4' end.

That is, the step motor 70 is connected to a gear mechanism 72 interposed between both the support member 14' and the support arm 30, and drives the gear mechanism 72 to rotate the support arm 30. Then, by operating the step motor 70 by a control device (not shown) in the same manner as in the first embodiment, the gear PR mechanism 72 is driven to obtain a completely controlled circular arc movement of the support arm 30.

Since the molded product ejecting device according to the second embodiment of the present invention is configured as described above, the support member 14 can be moved in the axial direction and rotated at any time by driving the electric motor 60, the step motor 70, etc. As in the first embodiment, the rotational movement can be performed simultaneously with the axial movement during the separation movement of the back plates 7 and 9, reducing the time required for the ejecting operation. .

The area around the engagement part between the support member 14' and the support arm 30 will be described when the rotation engagement part between the support member 14' and the support arm 30 is applied to a larger scale take-out device.

As shown in FIG. 7, an annular member 81, which is coupled to the outer cylindrical portion of the support member 14' via an annular member 80, is fitted into the fitting hole formed in the hub portion 83 of the support arm 30. It matches.

The main bearing 3 is located between the annular member 81 and the hub portion 83.
4. Washer 85. A secondary bearing 86a is interposed, and an annular holding plate 82 is attached to the main bearing 34. Washer 85. It is fixed to the annular member 81 so as to hold the sub-bearing 86a. Furthermore, a cover 87 is attached to the end surface of the hub portion 83. In addition, the cover 87 and the pressing plate 8
A sub-bearing 86b is interposed between the two.

Then, the holding plate 82 is attached to the sub bearings 86a and 86.
b, the hub portion 83 is held by the support member 14.
′ is fixed in the axial direction.

Further, the motor 70 is fixedly installed inside the support member 14', and its output shaft is connected to a gear mechanism 88. When the gear mechanism 88 is operated by the drive of the motor 70, the hub portion is attached to the presser plate 82 and the presser plate 82. The support arm 30 connected at 83 is adapted to be rotated about the axis of the support member 14'.

On the other hand, an annular plate 90b is fixed to the end surface of the hub portion 83 on the opposite side from the pressing plate 82, with an oil seal 90a interposed therebetween.

A key 91 is attached to the support member 14', and a key groove 92 that engages with the key 91 is fixed to the head 12. Inside the head 12, a arm 9 for an electric switch is provided for detecting the amount of movement of the support member 14' in the axial direction.
3 is installed.

Next, a modification of the area around the head 12 will be described. As shown in FIG. 8, a pneumatic cylinder 95 is installed in place of the motor 60. The cylinder 95 is provided with a shaft 96 which is actuated in the axial direction by the action of air pressure, and the shaft 96 is connected to the support member 14' by a transverse plate 164.

Then, the cylinder 9 is controlled by a control device (not shown).
5 is driven to move the support member 14' in the axial direction.

The movement V of the support member 14' by the cylinder 95 is shorter than that by the motor 60 of the second embodiment shown in FIG. 6, but if the molded product to be taken out is limited to a thin or small one In this case, sufficient functionality can be obtained at a lower cost than using the motor 60 described above.

Note that the electric motor 70 is used to rotate the support arm 30, as in the second embodiment, and the ejector 32 is adapted to a single molded product and does not have any replacement parts. good.

Furthermore, to explain a modified example of the support arm of the second embodiment of the present invention, the support arm 1 shown in FIG.
It has 30. The support arm 130 consists of an upper arm section 131 and a lower arm section 132, which are connected by a hinge.

The pneumatic cylinder 10 installed on the upper arm 131
The piston rod 101 of the piston rod 1.01 is connected to the one-way extension 102 of the lower arm portion 132, and the piston rod 101 of the piston rod 1.01 is
By extending and contracting the lower arm portion 132, the lower arm portion 132 is rotationally driven around J. The pneumatic cylinder 100 is driven by instructions from a control device.

With the above configuration, the molded product is taken out as follows. First, as shown by the solid line in FIG. 9, the piston rod 101 is fully extended and the upper arm portion 13
1 and lower arm portion 132 are driven to take-out positions 131X and 132X, respectively.

Then, the electromagnetic safety pin 103 as a lock of the 7th type attached to the upper arm part 131 is attached to the lower arm part 1.
32 to completely fix the lower arm to the -1 arm 131.

After the molded product is taken out at the above-mentioned position, the support arm 130 is rotationally driven around the axis of the support member 14' together with the support member 14', and the arm part 131 and the lower arm part 132 are respectively rotated as shown in the figure. Move to positions 131Y and 132Y in the middle.

Further, - the electromagnetic safety bin 103 is released, the pneumatic cylinder 100 is driven to contract, and the lower arm portion 132 is rotated to a position 1327 in the figure on the outside.

By driving the support arm 130 in this manner, the position from which the molded product is ejected can be lowered compared to the molded product ejecting device of the first embodiment shown in FIG. At the same time, damage to the molded product can be prevented, and the amount of rotational drive of the support member 14 can be suppressed to a smaller value.

Next, an example in which a servo motor is used instead of the cylinder 100 will be explained.

As shown in Figure 10a, the pivot)
Equipped with a gear mechanism 136 for driving J and a shaft 135 for driving this, the same shaft 7)] 35
is directly connected to a servo motor (not shown) attached near the same vivo.

By using a servo motor (not shown) in place of the pneumatic cylinder 100 in this manner, the support arm 130 can be completely controlled even during the drive, and the support arm 130 can be controlled by a computer or the like as a control device (not shown). It becomes possible to completely control the movement trajectory of the take-out shell 32 attached to the tip.

Furthermore, instead of directly connecting the shaft 7) 135 to the servo motor mounted near the shaft 12, an example is shown in which the shaft 7) 135 is connected via a belt to the servo motor mounted on the shaft 12". and FIG. 11.

In addition, in FIG. 10b, two different examples are shown below the dashed line -L indicating the central axis of the shaft 7) 135. Vivot) Sha 7 in J) 1i to 135
: In the above example, a pulley 140 is fixedly attached, and in the lower example, a pulley 141 is fixedly attached, and the pulley 140 or 141 is a servo attached around the head 12 by a bell) 200 as shown in FIG. It is connected to a motor M. As a result, the shaft 7) 195 is rotationally driven by the motor M (1).

Also, instead of the belt drive mentioned above, the pivot J
A mechanism may also be used in which the gears disposed in the head 12 are driven by a pinion gear attached to a servo motor (not shown) near the head 12.

Further, the gear mechanism causes the support arm 130 to move to the support member 14'.
A mechanism may be used in which the pivot J is driven at the same time as the pivot J is rotated.

The support can be achieved by arranging two servo motors on the head 12 or in close proximity to the head 12.
The weight of 111130 is reduced, which has the effect of reducing the required driving force.

In the examples shown in FIGS. 10b and 11 and the example shown in FIG. 10a, the control device also selectively controls the rotation of the support arm 130 around the support member 14'' and the drive of the pivot I. By doing so, it becomes possible to drive the extractor 32 so as to draw a smooth trajectory as shown in FIG.

In addition, as shown in FIG. 12, at the take-out position,
The lower arm portion 132 has reached the mold part breakthrough as in the case of FIG. By simultaneously rotating the lower arm 132 around J and under the control of a computer or the like, the tip of the lower arm 132 is once moved to the position 132Y while drawing a horizontal or nearly horizontal trajectory. As a result, the molded product has a tie bar in,
It becomes possible to pass between t and t without difficulty.

Further, since the support arm 130 is not rotated in the opposite direction around the support member 14' by a computer or the like, the pivot
By continuing to rotate in the direction of expansion, the lower arm 132
The tip of is moved to a position lower than the molded product release position in FIG. 9 at 132Z in the figure without drawing a smooth trajectory.

By completely controlling the movement of the support arm 130 in this way, the molded product can be taken out smoothly and accurately, and the time required for the taking out operation is shortened.
This allows the molded product release position to be set more freely.
