2. Description of the Related Art The applicant of the present invention has proposed a chip component mounting machine using a disc pack in a feeder section.
A disc pack is a large number of chip components that are aligned and stored in a storage path that continuously circulates. Since it has good interchangeability, when using the disc pack in the feeder part, an empty disc pack that has no chip components. Is replaced with a new disk pack (including chip parts), the chip parts to be mounted on the printed circuit board can be continuously supplied to the mounting head of the chip part mounting machine from the feeder section. Therefore, the chip component mounting machine can be operated for a long time without running out of components.

[0003]

By the way, when the disk pack stored in the feeder of the chip component mounting machine becomes empty (chip parts are exhausted), the empty disk pack is removed from the feeder and the stocker of the stocker is removed. It is necessary to sequentially perform the operation of returning to the empty disk pack placement space and the operation of taking out a new disk pack (with chip parts) from the stocker part and replenishing it to the feeder part, which takes time for replacement work was there.

In view of the above points, it is an object of the present invention to provide a disc pack exchanging device capable of promptly and surely exchanging disc packs between a feeder section and a stocker section of a chip component mounting machine. And

[0005]

In order to achieve the above object, a disk pack exchanging device of the present invention includes a feeder section for holding a disk pack containing chip components in an accommodating path that continuously circulates in an exchangeable manner. A stocker section for holding a spare disk pack in an exchangeable manner, and an exchanging section for exchanging the disc pack between the feeder section and the stocker section. A plurality of hand parts are provided, each of which has an engaging means that engages with the replacement engaging part so as to be opened and closed.

[0006]

In the disc pack exchanging device of the present invention, since the exchanging means is provided with a plurality of hand parts, a new disc pack of the same kind as the disc pack in which the chip parts are cut off (with the chip parts inserted) Take out from the stocker section with the first hand section and take it to the position facing the feeder section of the chip component mounting machine, take out the empty disk pack of the feeder section with the second hand section, and then hold it by the first hand section. Insert the new disc pack into the feeder section. As a result, one hand part makes one reciprocation between the stocker part and the feeder part to take out an empty disc pack, and then makes one reciprocation to supply a new disc pack. The pack exchange time can be shortened. In particular, when the number of disk packs arranged in the feeder is large and the necessity of disk pack replacement frequently arises, this effect of shortening the replacement time is useful.
