This type of counting box filling apparatus has a conveyor that sequentially conveys components, and the number of components conveyed by the conveyor is detected by the detector. The parts detected by this detector fall from the conveying terminal end of the conveyor and are supplied to a box or the like placed at the dropping point. Thereafter, when the detector detects and counts a predetermined number of parts, the driving of the conveyor is stopped, and the predetermined number of boxes are completed. Further, in the counting box filling device using a scale as a detecting means, the total weight of the box is always measured, and when the measured value reaches a predetermined value, the driving of the conveyor is stopped and the predetermined number of boxes are completed. . In order to continue boxing by the counting box packing apparatus having these configurations, the box that has been packed is replaced with an empty box, and the drive of the conveyor is restarted. However, in the parts boxing device having such a configuration, when the conveyor drive is immediately stopped, the parts at the conveyance end part fall due to inertia and parts exceeding the predetermined value are supplied to the box. was there. For the purpose of solving this problem, there is a counting box filling device shown in Patent Document 1. In this counting box filling device, when the value detected by the detector approaches a predetermined number, the conveyor is switched from high speed driving to low speed driving. In this low-speed driving state, when the predetermined number of parts are detected and counted, the driving of the conveyor is stopped. For this reason, the inertia applied to the component at the conveyance end portion is reduced, and the component at the conveyance end portion is configured not to fall unintentionally. That is, in the conventional counting box filling device, the supply amount is finely adjusted by gradually decreasing the driving speed of the conveyor. This action prevents excessive supply of parts.
