And a component detection sensor 155 that is disposed above the conveyance path 152 and detects the cover member C in the conveyance path 152. The side plate 153 and the upper plate 154 are plate members made of transparent resin.

The component detection sensor 155 is an overflow sensor that detects that the cover member C in the transport path 152 has reached a certain number or more, and is attached to the lower surface of the bottom plate 151 and extends upward from an upper end of a U-shaped sensor stay 156. Is attached. A control unit (not shown) of the parts feeder 110 controls the rotation of the component storage drum 120 based on information from the component detection sensor 155 so that a certain number of cover members C are not supplied into the conveyance path 152. To do.

Further, in this embodiment, as shown in FIG. 1, a component reversing device 160 that reverses the top and bottom of the cover member C is provided at the lower end portion of the chute 150 instead of the pallet 60 of the first embodiment.

In the parts feeder 110 of this embodiment, when performing lot switching, the current hopper 70 is removed, the guide unit 80 is opened, the current component storage drum 120 is replaced with the next component storage drum 120, and the guide unit 80 is replaced. Is closed, the next hopper 70 is set, and the cover member C in the conveyance path 152 of the chute 150 is collected.

As described above, according to the parts feeder 110 of this embodiment, the cover member C is stored, the component storage drum 120 that discharges the cover member C in a predetermined posture, and the drum rotation device that rotates the component storage drum 120. 30 and the chute 150 that slides down the cover member C discharged from the component storage drum 120, the lot can be switched by simply replacing the component storage drum 120. As a result, it is possible to reduce the number of parts to be replaced at the time of lot switching, and thus it is possible to reduce the time required for lot switching. Further, since the number of parts is small and the structure is simple as compared with the conventional vibration type parts feeder, the parts feeder 110 can be downsized. Further, since the parts are not conveyed by vibration, the durability of the parts feeder 110 can be improved and the noise can be reduced.

In addition, according to the parts feeder 110 of the present embodiment, the clogging removal device 170 that removes the clogging member 125 that clogs the component discharge groove 125 of the component storage drum 120 is provided. A decrease in the component discharge efficiency of the component storage drum 120 can be prevented.
About another structure and an effect, it is the same as that of the said 1st Embodiment.

In addition, this invention is not limited to what was illustrated to the said embodiment, In the range which does not deviate from the summary of this invention, it can change suitably.
For example, in each of the above embodiments, a hopper, a guide unit, and a hopper rotating device are provided, but these may be deleted if the parts are supplied to the part accommodating drum by an operator.
In each of the above embodiments, the positioning pin is provided on the rotating plate of the drum rotating device. However, the present invention is not limited to this, and the positioning pin may be provided on the bottom plate of the component housing drum, or both of them. A positioning pin may be provided.
In each of the above embodiments, the magnet is provided on the bottom plate of the component housing drum. However, the present invention is not limited to this, and the magnet may be provided on the rotating plate of the drum rotating device. It may be provided.
In the second embodiment, the component reversing device is provided in order for the cover member with the top plate facing downward to be discharged from the component discharge groove. However, the present invention is not limited to this, and the cover member with the top plate facing upward is provided. If the component is to be discharged from the component discharge groove, the component reversing device may be deleted.
Further, the clogging removal device of the second embodiment may be provided in the parts feeder of the first embodiment.
