Description

  The present invention relates to a reel stocker for storing a reel around which a tape holding a component (electronic component) supplied mainly to a component mounting machine is stored, and a component supply cart having a reel stocker mounted on a cart body.

  In a component mounter, a method using a tape feeder is frequently used as a method for supplying a component to a pickup position of a nozzle of a transfer head. In this method, a tape for holding a component is pulled out from the reel, and the pitch is fed in synchronization with the mounting timing of the component to be supplied to the nozzle. As described above, many of the package forms of the components supplied to the component mounting machine have a reel shape, and this reel is generally stored in a reel stocker of a component supply carriage on which a tape feeder is mounted.

  Since many types of components are mounted on the component mounting machine, a large number of tape feeders are required, and accordingly, a large number of reels for supplying components to the tape feeder are also required. Furthermore, in recent years, a method called “splicing” in which reels are prepared in advance and the tapes are connected while the component mounter is in operation has been put into practical use in order not to reduce the operating rate of the component mounter. Since it has been proposed, the number of reels to be stored in the reel stocker has greatly increased. As the number of reels increases, the reel stocker space becomes insufficient.

  On the other hand, Patent Document 1 proposes a reel stocker that can hold three reels on a plurality of side plates constituting a reel stocker in order to efficiently store a plurality of reels. However, since the reel stocker of Patent Document 1 holds as many as three reels on one side plate, it accompanies storage and exchange of reels such as attachment and replacement of reels to each side plate, and additional work such as collation at the time of reel replacement. There is a problem that workability of work is bad. Further, since the type (size) of the reel that can be held in the reel stocker of Patent Document 1 is limited by the side plate to be used, it cannot cope with the change of the type (size) of the reel and lacks versatility. There is also.
