The fixing member 51 on one side includes a fixing claw 51a having a tapered surface capable of abutting against a tapered surface of the abutment 26a disposed at both ends of the lid 22 of the transfer box 2, and a fixing claw 51a. It is composed of a pulling pin 51b supporting the claw 51a. The pin 51b is supported by the side plate 42a of the transfer box setting table 4 via a pin slide guide 51c so as to be movable in a direction parallel to the rotation center line 6a.
The coil spring, which is the spring member 52, is disposed in a compressed state between the back surface of the fixing claw 54 and the pin slide guide 51 c, and the pin that supports the fixing claw 51 a by the spring force of the spring member 52. 51b is always urged in the protruding direction, that is, the direction in which the transfer box 2 is pressed.

Is an arc-shaped groove centered at.

The transfer box fixing mechanism 5 on the other side has the same configuration.

In the transfer box fixing mechanism 5, when the air cylinder 55 is not operating, that is, in the state shown in FIG. 3, the fixing claws 51 a on both sides are moved by the spring force of the spring member 52 so that the lid 22 of the transfer box 2 is closed. Is pressed. Since both the fixing claw 51a and the abutment 26a have tapered surfaces, the transfer box 2 as a whole is pressed and pinched by the fixing claw, and the lid 22 is pressed against the box body 21 side. As a result, transfer box 2
Is fixed to the transfer box installation table 4 with the lid 22 closed. In this fixed state, when the transfer box 2 swings together with the transfer box installation table 4 about the rotation center line 6a by the rotation mechanism 6 described later, the pin 51b fitted in the groove 54a of the fixed-side connection fitting 54.
Is movable along the arc-shaped groove 54a. Therefore, there is no hindrance to the swing operation of the transfer box 2 even in the fixed state.

Next, when the air cylinder 55 is driven to retract the operating rod 55a, the constricted portion of the groove 54a of the connecting metal fitting 54 at its tip engages with the flange 51e of the pin 51b, and the pin 51b is turned into a spring force. Pull against. As a result, the fixing claws 51a are separated from the transfer box 2, and the fixed state of the transfer box 2 is released. At the same time, the transfer box lid 22
Will also be free to open.

(Rotation Mechanism) The rotation mechanism 6 will be described with reference to FIG. The rotation mechanism 6 has rotation shafts 61a, 61b extending coaxially from the outer surfaces of the side plates 42a, 42b on both sides of the transfer box installation table 4 along the rotation center line 6a. The rotating shafts 61a and 61b are respectively provided with a pair of left and right vertical brackets 71 constituting a sliding mechanism 7 described later.
a and 71b rotatably supported.
The tip of one rotation shaft 61a penetrates the bracket 71a and protrudes outward, and a driven sprocket 62 is fixed to this protruding portion. The output shaft 63 of the transfer box rotating motor 63 is located immediately below the sprocket 62.
A drive-side sprocket 64 is fixed to the end of a, and a timing belt 65 is stretched between them. The motor 63 is supported by a slide mechanism 7 described later via a bracket.

When the transfer box rotating motor 63 is driven, the transfer box installation table 4 on which the transfer box 2 is installed can be rotated about the rotation center line 6a. In this example, the transfer box installation table 4 is swung within a certain angle range by controlling the driving of the motor 63.

(Slide Mechanism) The slide mechanism 7 will be described with reference to FIGS. The slide mechanism 7 eccentrically rotates about a slide table 72, a slide guide 73 that supports the slide table 72 so as to be able to reciprocate linearly in the direction of the rotation center line 6 a, and a perpendicular line 7 a orthogonal to the slide table 72. An eccentric roller 74 and a roller receiver 75 supported on the slide table 72 are provided.

The roller receiver 75 has a circular inner peripheral surface large enough to fit the eccentric roller 74. In addition, the roller receiver 75 is provided on the back surface of the slide table 72 via the slide guide 76 in a direction orthogonal to the direction of the rotation center line 6a, that is, the slide table 7
2 is supported so as to be able to reciprocate in a direction orthogonal to the sliding direction.

The eccentric roller 74 is supported by a roller support member 77. The roller support member 77 is connected to the output shaft of the transfer box slide motor 78,
Rotate around a. The center of the eccentric roller 74 is located at a position 7b eccentric by e with respect to the perpendicular 7a (motor rotation axis) by the roller supporting member 77.

When the motor 78 is driven, the eccentric roller 74 supported by the roller supporting member 77 rotates eccentrically about the perpendicular line 7a by an eccentric amount e. The eccentric roller 74 is in contact with a roller receiver 75 slidable in a direction perpendicular to the direction in which the eccentric roller 74 can slide with respect to the slide table 72. Therefore, when the eccentric roller 74 rotates eccentrically, the slide table 72 reciprocates linearly in the sliding direction.

Here, as can be seen from FIG. 4, the roller support member 77 includes an eccentric frame 77a supporting the roller shaft 74a of the eccentric roller 74, and the eccentric frame 77a is moved in the sliding direction B of the slide table 72. Is a guide surface 77b movably supported in the orthogonal direction A, and an eccentric amount adjusting bolt 77c capable of adjusting the position of the eccentric piece 77a.
And If the position of the eccentric piece 77a is moved in the direction of arrow A by the eccentric amount adjusting bolt 77c, the eccentric amount of the eccentric roller 74 can be changed. In other words, the stroke of the slide table 72 can be adjusted.

(Transfer Box Lid Transport Mechanism) In FIG. 5,
An example of a lid transport mechanism suitable for transporting a lid 22 of a transfer box of the transfer apparatus 1 of the present example is shown. From the lower surface of the transfer arm 81 of the transfer mechanism 8, a pair of magnet holders 8
2, 83 extend vertically. Disc-shaped magnets 84, 8 are provided on the lower end surfaces of these magnet holders 82, 83, respectively.
5 is fixed by bonding or the like. Each magnet 8
Guide pins 86 and 87 project vertically downward from the centers of 4 and 85. These guide pins 86, 8
The pin holes 29a and 29b into which 7 can be inserted are formed in the centers of the magnet chuck fittings 27a and 27b of the lid 22. A cylinder 88 for releasing the lid chuck is vertically attached to the transfer arm 81 between the magnets 84 and 85, and the operating rod 88a can protrude downward. .

When transferring the lid 22, the transport mechanism 8 having this configuration positions the arm 81 immediately above the lid 22. Then, the arm 81 is lowered, and the corresponding magnet chuck fittings 27a, 27b are attracted by the magnetic force by the pair of magnets 84, 85. As a result, the lid 22 is chucked on the side of the transfer arm 81 as shown in FIG. In order to release the chucking of the lid 22, the cylinder 88 may be driven to pull the lid 22 downward by the operating rod 88a.

(Operation of Transfer Apparatus) The operation of the transfer apparatus 1 configured as described above will be described. First, a large number of small parts to be transferred are put into the transfer box 2 and the lid 22 is covered. Then, the transfer box fixing mechanism 5 is held in a released state, and the transfer box 2
Is set on the transfer box setting table 4. After the transfer box 2 is installed, the transfer box 2 is fixed to the transfer box installation table 4 by the transfer box fixing mechanism 5. FIG. 1 shows this state.

Next, the rotation mechanism 6 is driven to invert the transfer box setting table 4 to which the transfer box 2 is fixed, by 180 degrees, and the drive mechanism 6 is temporarily stopped in the inverted state. In this inverted state, the lid 22 is located on the lower side, and a large number of small components are accumulated on the transfer pattern 24 formed on the upper surface thereof. Thereafter, the transfer box 2 is swung in a certain angle range around the rotation center line 6a by repeating the normal rotation and the reverse rotation of the rotation mechanism 6.

At the same time, the slide mechanism 7 is also driven. When the slide mechanism 7 is driven, the slide table 72 starts reciprocating linear motion with a constant stroke in the direction B parallel to the rotation center line 6a. The rotation mechanism 6 and the transfer box setting table 4 are supported by the slide mechanism 7. Therefore, the transfer box installation table 4 on which the transfer box 2 is installed swings around the rotation center line 6a while performing a reciprocating linear motion in the direction of arrow B. Therefore, the transfer box 2 makes a composite reciprocating motion. By being given such a combined reciprocating motion, the small parts put into the transfer box 2 are efficiently transferred into the transfer recess 23 constituting the transfer pattern 24.

Here, each of the transfer recesses 23 is sucked and brought into a reduced pressure state. Therefore, the transfer recess 2
The component transferred to 3 is not sucked there and does not fall off.

After the combined reciprocating motion is given to the transfer box 2 for a certain period, the rotation mechanism 6 and the slide mechanism 7 are stopped. Then, the rotating mechanism 6 is driven to invert the transfer box 2 by 180 degrees and return to the state shown in FIG. Thereafter, the fixing by the transfer box fixing mechanism 5 is released, and the lid 22 is made removable.

In this state, the cover 22 is attracted by the magnetic force using the transfer arm 81 and is transferred in a predetermined case. Then, the parts are transferred while being aligned with a jig (not shown) waiting in advance. In this operation, for example, it is desirable to reliably transfer the components transferred to the respective transfer recesses 23 to the jig side using a knock pin.

Thereafter, the same operation is repeated, and the transfer box 2
Performs the transfer operation of the components inserted in

[0044]

As described above, in the transfer apparatus of the present invention, the transfer box is made to perform a complex reciprocating motion of swinging in a fixed angle range and reciprocating linearly, thereby efficiently removing parts. A transfer operation can be performed.

Further, the fixing mechanism for fixing the transfer box to the transfer box installation table can be fixed to the transfer box installation table in a state where the transfer box can swing, so that the transfer box swing mechanism can be realized with a simple configuration. .

Further, the slide mechanism for sliding the transfer box is configured to change the stroke in the sliding direction. Therefore, since the transfer box can be slid with a stroke corresponding to the part to be transferred, an efficient transfer operation can be realized.

Further, since the cover of the transfer box can be used as it is as a transfer tool for transferring the transferred components, the mechanism is simpler than in the case where a dedicated transfer tool is used as in the prior art. Efficiency is also improved.

In addition, when transferring the lid of the transfer box, the lid is chucked using the magnetic force of a magnet. There is an advantage that there is no possibility of being canceled and being canceled.
