It is fed within a. The chip-type electronic components 52 on the magazine 51 are continuously supplied into the workpiece feeding hole 3a by air blown out from the air blowing hole 4 while the magazine 51 is being fed. The chip type electronic component 52 passing through the work feed hole 3a is detected by the counting fiber sensor 16a, and the counter 30 performs counting. When the count value of the counter 30 reaches a first preset value, which is set by subtracting several items from the desired number of items stored in the stake 50, the counter 30 outputs a first set signal to the controller 31. The controller 31 decelerates the motor 14 to a speed at which it can be instantaneously stopped. Furthermore, when the count value of the counter 30 reaches a second preset value set to the desired number of stored items in the stake 50, the counter 30 outputs a second set signal to the controller 31. The controller 31 instantaneously stops the motor 14. With the above operation,
Feeding and storing a certain number of chip-type electronic components 52 into the stake 50 is completed.

[Effects of the invention] As explained above, according to the invention, chip-type electronic components are taken out individually from the top of the magazine, and the electronic components are stored in an empty stake in order in a row. At this time, the number of stored electronic components is counted using a combination of a photoelectric sensor and a counter, and the supply of electronic components is terminated when the counted value reaches a predetermined number of stored electronic components, which prevents missing electronic components on the magazine. Even if this occurs, a predetermined number of electronic components can be stored in the stake.

In addition, since the electronic components on the magazine are individually taken out and supplied into the stakes, compared to the conventional case where multiple electronic components on the magazine are transferred into multiple stakes at the same time, the electronic components are Positioning of the stake can be done easily,
No skill level is required for the work, and anyone can perform the work smoothly.

Furthermore, the controller decelerates the feed speed of the magazine by receiving the deceleration command output from the counter, and terminates the supply of electronic components when the number of electronic components in the stake reaches a set value. Since excess electronic components are prohibited from being stored in the stake, there is no need to provide a stopper mechanism for opening and closing the workpiece feeding path through which the electronic components are fed, and the structure can be simplified.
