[Industrial applications]

 The present invention relates to a component supply device that can smoothly supply components to a component supply device that supplies components to an automatic assembly machine or the like.

[0002]

[Prior Art]

 Generally, a component supply device that supplies components to an automatic assembly machine requires a component supply device so that components can be continuously supplied without interruption. As this component replenishing device, there is the component replenishing device 1 shown in FIG. 3 which has been developed to enable smooth replenishment work. The component replenishing device 1 has a mounting plate 4a having an upright portion, and the mounting plate 4a is arranged with a predetermined angle with respect to the component supplying device 2 by an engaging metal fitting 3 and an abutting metal fitting 12. ing. A motor 5 is arranged on the rear surface of the upright portion of the mounting plate 4a, and the rotational force of the motor 5 is transmitted to one of the rollers 9 described later. Further, rollers 9 which rotate at predetermined intervals are arranged on the mounting plate 4a at four positions via roller bases 13, and these four rollers 9 are made of resin and have a cylindrical shape with an upper opening. It supports the bottomed drum 7. These rollers 9 guide the outer peripheral surface of the bottomed drum 7, and the bottomed drum 7 is configured to be rotatable while maintaining an inclined posture. Further, a ball caster 11 mounted on the upright portion of the mounting plate 4a is arranged so as to come into contact with the bottom surface of the bottomed drum 7, and the ball caster 11 is located at the center of rotation of the bottomed drum 7. Is configured to be. On the other hand, a part of the open end of the bottomed drum 7 projects from the end of the mounting plate 4a, and a spiral guide plate 10 for transferring parts is arranged on the inner peripheral surface of the bottomed drum 7. When the bottomed drum 7 rotates, the components inside the bottomed drum 7 are sequentially sent out upward along the spiral guide plate 10.

In the component replenishing device 1, the rotational force of the motor 5 is transmitted to one of the rollers 9, and the roller 9 rotates the bottomed drum 7 while guiding the outer peripheral surface of the bottomed drum 7. Therefore, the component in the bottomed drum 7 is fed upward along the spiral guide plate 10, and this component is replenished to the component supply device 2 from the opening side of the bottomed drum 7.

However, the rotational force of the motor 5 is transmitted only to one of the rollers 9, and when the number of parts in the bottomed drum 7 becomes small, the roller 9 idles and the rotational force cannot be transmitted to the bottomed drum 7. .. Therefore, there is a drawback that the component is not delivered upward along the guide plate 10 and the component is not delivered to the component supply device 2.

[0005]

[Problems to be solved by the device]

 The problem to be solved is that the rotational force of the rotary drive source provided in the component supply device 1 cannot be reliably transmitted to the bottomed drum 7.

[0006]

[Means for Solving the Problems]

 The component replenishing device is provided with a rotary drive source that forms a part of the rotation transmitting means, and the rotational force of the rotary drive source is transmitted to each rotary object support member disposed at a plurality of positions of the mounting portion. Is configured. Further, a cylindrical bottomed drum with an upper opening is held by these rotating object support members so that a part of the drum is projected from the end of the mounting portion, and the bottomed drum is configured to be rotatable. ing. Furthermore, an engaging metal fitting that engages with the upper portion of the component supply device is fixed to the attachment portion, and the bottomed drum is inclined and can be attached. Further, a ball caster is provided at this mounting portion so as to support the bottom surface of the bottomed drum, and is configured to rotatably support the bottomed drum together with the rotating object support member. A spiral transfer path for transferring parts is arranged on the inner peripheral surface of the bottomed drum, and when the bottomed drum rotates, the parts in the bottomed drum are sent upward along the transfer path. It is configured.

[0007]

[Action]

 In the above component replenishing device, since the rotating object supporting member that is in contact with the outer peripheral surface of the bottomed drum rotates a plurality of times, the bottomed drum rotates reliably, and smooth component replenishment can be performed even if the number of parts decreases. You can
