Next, referring to FIG. 14 and FIG. 15, the method of the present invention will be described in detail. First, as shown in FIG. 4 sent on the holder 38
The one plate-shaped component 1 to 4 is the component automatic laminating apparatus 1 of the present invention.
It is held by the holding claws 58 and 58 'of the four component stacking holding jigs 42A to 42D. After each of the component stacking jigs 42A to 42D grips each component in this way, the movable assembly holder 38 retracts from the component stacking and holding means 44 of the apparatus of the present invention.
As shown in FIG. 14A, each component stacking and holding jig 42A
To 42D, the component loading parts 48A to 48D of the component loading means 50 are located.

Next, as shown in FIG. 14 (B), the component loading / holding means lifting mechanism 4 is instructed by the control means 84.
The piston 68a of the lifting cylinder 68 of No. 6 extends and the component loading and gripping means 44 descends, and each component loading and gripping jig 42A.
The components 1 to 4 gripped by the components mounting means 50 to 42D are loaded on the corresponding component mounting portions 48A to 48D of the component mounting means 50, and at this time, the component loading and holding jigs 42B and 42D corresponding to the components 2 and 4 are loaded. Only the gripping claws 58, 58 'are released by the activation of the rotary actuator, the other parts 1 and 3 are
Grasping claws 5 of the corresponding component laminated gripping jigs 42A, 42C
Leave 8, 58 'closed. In FIG. 14B, only the component stacking and holding jigs 42B and 42D are lowered, and the component stacking and holding jigs 42A and 42C are kept in the raised position, which are adjacent to each other in the drawing. This is because the gripping claws of the jigs are described in such directions and intervals that they interfere with each other when they are opened and closed. In reality, the four jigs move up and down at the same time. Since they are provided so as to face each other on the front side and the back side of the paper so as not to interfere with each other, they do not interfere with each other. After that, the component stacking / holding means lifting mechanism 46 moves the lifting cylinder 6
8 by the contraction of the piston 68a
Ascend to 4.

Next, as shown in FIG. 14C, the control means 84 activates the component mounting means transfer mechanism 52 to move the component mounting portions 48A to 48D of the component mounting means 50 in the direction in which they are aligned. In the left direction of FIG. 14, the component placement parts 48A to 48
The components 2 and 4 on the component placement parts 48B and 48D are positioned below the component stacking and grasping jigs 42A and 42C that respectively grasp the components 1 and 3 by moving by the distance D of D.

In this way, parts 1 and 2 and parts 3 and 4
In the state where the components are vertically aligned, the control means 84 activates the component stacking and holding jig elevating mechanism 46 to lower the component stacking and holding means 44, and the component 2 on the component mounting portion 48B is the component stacking and holding jig. By opening and closing the grip claws 58, 58 'of 42A, the component 1
16A to 16C (see FIGS. 16A to 16C), and the component 3 in the component stacking and grasping jig 42C is placed on the component 4 on the component placing portion 48D, and its grasping claw 58, 5
8'is opened and the component 3 is released for placement, and the components 3 and 4 are stacked by pressing the pressing plate 60A. The component stacking gripping means 44 is once returned to the raised position by the component stacking gripping means elevating mechanism 46.

As can be seen from FIGS. 16 (A) and 16 (B), when the component stacking and holding jig 42A is lowered, the holding claws 58 and 58 'interfere with the component 2 on the component loading section 48B. , The grip claws 58, 58 'have curved surfaces 59, 5 on their lower surfaces.
Since it has 9 ', it opens against the springs 92, 92' along the slope of this curved surface 59, 59 'to dive underneath the component 2, so that the gripping pawls 58, 58' have their rotary actuators. Open and close without driving, and with component 1, component 2
Can be gripped.

Thereafter, as shown in FIG. 14 (D), the control means 84 activates the component placement means transfer mechanism 52 to move the component placement means 50 leftward in FIG. The component placing portion 48D on which the components 3 and 4 are placed is positioned below the component stacking / holding jig 42A that holds the components 1 and 2. In this state, the control means 84 activates the component stacking / holding means elevating mechanism 46 to lower the component stacking / holding means 44, and the component 2 gripped by the component stacking / holding jig 42A.
1 is placed on the components 3 and 4 on the component mounting portion 48D while releasing the gripping claws 58 and 58 ', and the components 1 to 4 are stacked by pressing the pressing plate 60A, and then the component stacking and holding jig 42A is pressed. The grip claws 58, 58 ′ are the stacked components 1
4 to 4 are closed so that they are held together.

Since the control means 84 activates the component stacking / holding means elevating mechanism 46 to raise the component stacking / holding means 44, the stacked components 1 to 4 rise while being held by the component stacking / holding jig 42A. After that, as shown in FIG. 15, the component placement means transfer mechanism 52 further moves to the left of FIG. 15 so that the component placement means 50 is disengaged from the component stacking and holding jig 42A holding the components 1 to 4. Parts placement means 50
To move. As can be seen from FIG. 15, the carry-out conveyor 40
Since the entrance of the component overlaps the component placement means 50, the laminated components 1 to 4 are located on the carry-out conveyor 40, and the control means 84 activates the component lamination gripping means elevating mechanism 46 to grip the component lamination gripping. By lowering the means 44, the component stacking and holding jig 42A can release the stacked components 1 to 4 and transfer them to the carry-out conveyor 40 in the stacked state (see the broken line in FIG. 15). The carry-out conveyor 40 sends these laminated parts to the next processing step.

Still another modification of the present invention is shown in FIGS.
8 and in the modification of FIG. 17, the component stacking gripping means 4
Each of the component stacking and holding jigs 42A to 42D of No. 4 has a deformed direction of the claw portions of the gripping claws 58 and 58 'facing each other. That is, the claw portions 58a and 58'b face each other at one diagonal position, and the claw portions 58b and 58'a face each other at the other diagonal position. In this way, the four claw portions 58a and 58'b, which are diagonally opposed to each other,
As the part is gripped by 8b and 58'a, the part is automatically placed in position in the gripping pawls 58,58 '. Therefore, in this modified example, the component positioning means 86 is not necessarily required, but in the illustrated embodiment, the component positioning means 86 is shown to be provided auxiliary.

In the modification of FIG. 18, the grip claws 58, 58 'of the component stacking grip jigs 42A to 42D are provided only at one diagonal position, and the grip claws 58, 58' are
It has an L-shaped gripping surface so as to cover the edges of two adjacent sides. Therefore, also in this modified example, since the gripping claw itself has a function of positioning the component at a predetermined position, the component positioning means can be omitted.

In the above-described embodiment, the component placing means 50 is horizontally moved with the interval of the component placing portions as a unit to sequentially laminate the components. However, the component placing means 50 is fixed and the component stacking / holding means 44 is fixed. You may move the side horizontally. Further, in the above embodiment, four parts are first laminated two by two to form two two-part combinations, and then these two two-part combinations are laminated together to form a combination of all parts (four parts). Although they were stacked in stages, for example, when stacking 8 parts,
First, four (half of the number of parts) two-part combination, and then two of these four two-part combinations are combined into two (four-half) four-part combinations, and finally, these two four-part combinations. The parts combination is laminated to form a combination of all parts (8 parts) in three stages. In this case, the pitch of the horizontal movement of the component placement means 50 is the interval between adjacent components in the first stage movement, and is two component intervals and four component intervals in the second and third stage movements, respectively. .
Of course, the present invention can be applied to other multi-stage laminations besides the lamination of four and eight parts.

[0041]

Place half of the gripped multiple plate-like parts on the corresponding parts placement part, and place the parts on the parts placement part so that the parts on the parts stacking jig correspond. After the parts or parts stacking gripping jig is relatively displaced, the parts on the parts stacking gripping jig are placed on the parts on the parts placement part to be stacked and half the number of the initial parts The component stack is formed, and half of the half of the component stack is gripped by the component stack gripping jig, and then the component mounting part or the component stack gripping jig is relatively displaced again to stack the component stack. Place and stack the component stack on the gripping jig on the component stack on the component mount. And, since repeat the above operations until all the parts to be laminated are laminated, it is possible to sequentially easily laminated plate-shaped parts.

In addition to the component mounting means having a plurality of component mounting portions for mounting a plurality of components and the component stacking and holding means having the component stacking and holding jigs corresponding to the respective component mounting portions, Each component stacking and holding jig is moved up and down for each intermittent transfer of the component placement section, and only a mechanism for selectively driving the component stacking and holding jig conveys and grips a plurality of components so that they are sequentially stacked in a predetermined order. As a result, it is possible to economically stack components automatically with a low equipment cost and a small installation space.

Further, the component stacking and holding jig positions the parts at a predetermined position when gripping the corresponding parts, and positions the parts at a predetermined position when gripping the corresponding parts so that the parts are aligned with each other during stacking. Since the component positioning means is provided, the component stacking and holding jig is particularly suitable for the case where the components need to be aligned with each other, as in the case where a plurality of components have protrusions such as terminals penetrating each other so as to be intertwined with each other. Since the parts are automatically aligned when gripping the parts, the parts conveying means does not need to precisely control the positions of the parts, which facilitates the control.
