[0002]

2. Description of the Related Art The present applicant has proposed a chip component mounting machine using a disk pack in a feeder section.
A disk pack is one in which a large number of chip components are arranged and stored in a continuously circulating storage path, and because of its good interchangeability, when a disk pack is used in the feeder, an empty disk pack with no chip components is used. Is replaced with a new disk pack (containing chip components), the chip components to be mounted on the printed circuit board can be continuously supplied from the feeder unit to the mounting head of the chip component mounting machine. Accordingly, it is possible to operate the chip component mounting machine for a long time without running out of components.

[0003]

When a variety of disc packs are provided in the feeder section of the chip component mounting machine, when empty disc packs are removed from the feeder section and new disc packs are refilled from the stocker section. In addition, it becomes necessary to identify the type of the chip component stored in each disk pack on the replacement means side. Therefore, a configuration for easily and surely identifying the type of chip component in the disk pack has been desired.

In view of the above points, the present invention expresses the type of chip components stored in the disk pack by a bar code attached to the outer surface of the disk pack, and reads the bar code with a bar code reader on the replacement means side. It is an object of the present invention to provide a disk pack changing apparatus capable of smoothly and reliably performing a disk pack changing operation in a case where various types of disk packs are arranged in a feeder section and a stocker section.

[0005]

In order to achieve the above-mentioned object, a disk pack changing apparatus according to the present invention comprises a feeder section for freely holding a disk pack containing chip components in a continuously circulating storage path. In the case where the disk pack has a stocker section for holding a spare disk pack so as to be exchangeable, and an exchange means for exchanging the disk pack between the feeder section and the stocker section, the disk pack is attached to the suction step.

The X-direction moving frame 22 is integrated with a cover member 40 for covering the inverted L-shaped support frame 24, the Y-direction slider 26, and a drive mechanism thereof. The leader 45 is fixed. That is, the bar code reader 45 can move in the X direction along with the movement of the X direction moving frame 22 in the X direction, and its height can be read by reading the bar code 5 of the disk pack 2 exchangeably held by the stocker unit 9. Are positioned so as to be able to face each other.

An X-direction ball screw shaft 31 screwed to the ball screw nut 30 on the X-direction moving frame 22 is connected to a motor 32.
, The X direction moving frame 22 is driven in the X direction. A Z-direction ball screw shaft 33 is rotatably supported on the X-direction moving frame 22. The Z-direction ball screw shaft 33 is screwed into a ball screw nut 34 on the inverted L-shaped support frame 24 side. I have. Therefore, the Z-direction ball screw shaft 33
Is rotated by a motor 35, whereby the inverted L-shaped support frame 24 is driven in the Z direction (up and down direction). Further, a Y-direction ball screw shaft 36 is rotatably supported on the inverted L-shaped support frame 24, and the Y-direction ball screw shaft 36 is screwed to a ball screw nut 37 on the Y-direction slider 26 side. .
Accordingly, the Y-direction slider 26 is driven in the Y-direction (lateral direction) by rotating the Y-direction ball screw shaft 36 with the motor 38. As a result, the hand section 20 is XY-
It becomes movable in the Z direction.

As shown in FIG. 4, the hand unit 20 has slide rods 81A and 81B slidably mounted in a vertical direction on a support plate 27 via a thrust bearing 80.
And parallel bars 70A, 70B fixed to the ends of the slide rods 81A, 81B and movable in parallel, and engagement hooks 71A, 71B fixed to face the tips of the parallel bars 70A, 70B to each other. Parallel bars 70A, 70
B, each of which has a ball plunger 72 (a component that urges a ball in a protruding direction by a spring) attached to a tip end surface of B. A U-shaped engaging member 82 is fixed to an intermediate portion between the slide rods 81A and 81B. A rotary actuator 83 is attached to the support plate 27, and a pin 85 that engages with the U-shaped engagement member 82 is fixed to a rotary plate 84 fixed to a rotation shaft of the rotary actuator 83.

The engaging hooks 71A, 71B are shaped so as to be able to engage with the replacement engaging portions 3 on the upper and lower ends of the rear end of the disk pack 2, and the rotary actuator 83 rotates the rotary plate 84 counterclockwise. With both hooks 71A, 71B
The distance between the hooks 71A and 71B can be increased by narrowing and reversing the distance between the two hooks, and by combining the movement of the support plate 27 in the XYZ directions and the opening and closing of the hooks 71A and 71B. 2 can be held, transported, or released.

As shown in FIG. 2, an upper guide member 50 is fixed to the inverted L-shaped support frame 24 so as to engage with the upper side of the disc pack 2 held by the hand portion 20.

Next, the operation of the above embodiment will be described. The feeder unit 8 is provided with a component sensor for detecting the remaining amount of chip components in each disk pack 2. When detecting the absence of chip components of a specific disk pack 2, the feeder unit 8 has a hand unit 20 based on the detection result. The exchange means starts operating. That is, the open disk pack 2 of the feeder unit 8 is taken out by using the opening / closing of the hand unit 20 and the operation in the XYZ directions, and is returned to the empty disk pack storage area of the stocker unit 9. Of the same type as the above-mentioned disk pack with no components (contains chip components of the same type)
The disk pack 2 is searched while the bar code reader 45 is moved in the X direction, and a disk pack 2 having the same bar code 5 as that of the disk pack with no components is found. Then, the new disk pack 2 having the same bar code is chucked from the stocker unit 9 by using the opening and closing of the hand unit 20 and the movement in the XYZ directions, and is moved to the feeder unit 8. Insert into 8. that time,
The difference between the required insertion amount of the disk pack 2 into the feeder unit 8 and the movement amount of the hand unit 20 during insertion is determined by the parallel bars 70A, 7A.
The ball is absorbed by a ball plunger 72 fixed to the front end face of the head 0B. That is, at the end of the insertion operation, the ball of the ball plunger 72 comes into contact with the rear end face of the disc pack 2 and pushes the disc pack 2 until it is positioned by the feeder unit 8.

[0017]

As described above, according to the disk pack exchanging device of the present invention, the type of the chip component stored in the disk pack is determined by the shape of the engaging portion for exchanging the disk pack.
