Abstract

A bulk component supply system which includes a bulk component supply device which is moved together with a mounting head; and a method for replenishing bulk components to that bulk component supply device are disclosed. A passage-equipped component case of a bulk component supply device which is moved together with a mounting head is removed, held by the empty one of case holding sections of a slide in the bulk head component case exchange region. Bulk components are replenished and a passage-equipped component case held on the other of the case holding sections is held on the mounting head. The slide is moved to a bulk component replenishment region, and components are automatically replenished from bulk component storage vessel to the passage-equipped component case received from the mounting head which is empty. After replenishment, the slide is moved to a bulk component case exchange region.

First claim

The invention claimed is:

1. A bulk component supply system comprising:
a bulk component supply device which is movable together with a mounting head for mounting bulk components on a circuit substrate, the bulk component supply device including:
a bulk component case which houses electronic circuit components in a loosely packed state as bulk components,
a component passage which arranges bulk components in a line and guides the bulk components to a component supply section, and
a supply device use bulk component transfer device which transfers bulk components inside the bulk component case to the component passage; and

a bulk component case moving device to remove the bulk component case from the mounting head and move the bulk component case to a bulk component replenishment region,
wherein bulk components can be replenished to the bulk component case moved to the bulk component replenishment region,
wherein the bulk component supply system includes first and second bulk component cases,
wherein the bulk component case moving device includes a first case holding section which holds the first bulk component case removed from the mounting head, a second case holding section which holds the second bulk component case to which bulk components were replenished, a first case holding section raising and lowering device which raises and lowers the first case holding section, and a second case holding section raising and lowering device which raises and lowers the second case holding section, and
wherein the first bulk component case is received from the mounting head to the first case holding section by using the first case holding section raising and lowering device, and the second bulk component case is delivered to the mounting head from the second case holding section by using the second case holding section raising and lowering device.

2. The bulk component supply system according to claim 1 , further comprising:
a bulk component storage vessel which stores bulk components, has a larger capacity than the second bulk component case, and is provided in the bulk component replenishment region; and
a component replenishment device which replenishes bulk components from the bulk component storage vessel to the first bulk component case moved to the bulk component replenishment region.

3. The bulk component supply system according to claim 2 , further comprising:
a connecting device which replenishes bulk components by connecting a component inlet of the first bulk component case moved to the bulk component replenishment region and a component outflow path which outflows bulk components of the bulk component storage vessel; and
a storage vessel use bulk component transfer device which transfers the bulk components in the bulk component storage vessel to the component outflow path.

4. The bulk component supply system according to claim 2 ,
wherein the bulk component storage vessel is equipped with a storage vessel related information holding section which holds storage vessel related information including at least one of: (a) storage vessel identification information by which it is possible to individually identify the bulk component storage vessel itself; (b) storage vessel type information which is information of the type of the bulk component storage vessel itself; and (c) information of the type of the bulk component stored in the bulk component storage vessel;
wherein the first and second bulk component cases are each equipped with a component case related information holding section which holds component case related information including at least one of: (d) component case identification information which can individually identify the respective bulk component case itself; (e) information of the type of the respective bulk component case itself; and (f) information of the type of bulk components already housed in that respective bulk component case;
wherein the bulk component supply system further includes a storage vessel/component case information acquisition device which acquires: storage vessel related information of that storage vessel related information holding section; and component case related information of that component case related information holding section; and
wherein the bulk component supply system includes at least one of:
a storage vessel/component case not appropriate notification device which provides a notice when the storage vessel related information and the component case related information acquired by the storage vessel/component case information acquisition device is not appropriate; and
a replenishment prevention device which prevents replenishment of bulk components to the second bulk component case from the bulk component storage vessel when the storage vessel related information and the component case related information acquired by the storage vessel/component case information acquisition device is not appropriate.

5. The bulk component supply system according to claim 1 , wherein the bulk component case moving device includes:
a movable member which is equipped with the first and second case holding sections and which is movable to the bulk component replenishment region and a bulk component case exchange region;
a movable member driving device which moves that movable member to the bulk component replenishment region and the bulk component case exchange region; and
a bulk component case exchange device which, at the bulk component case exchange region, receives and holds the first bulk component case from the mounting head using the first case holding section, and delivers the second bulk component case to the mounting head using the second case holding section.

6. The bulk component supply system according to claim 1 ,
wherein the first and second bulk component cases are each equipped with a component case related information holding section which holds component case related information including at least one of: (a) component case identification information which can individually identify the respective bulk component case itself: (b) information of the type of the respective bulk component case itself; and (c) information of the type of bulk components already housed in that respective bulk component case;
wherein the mounting head is equipped with a component case related information acquisition device which acquires component case related information of the component case related information holding section; and
wherein the bulk component supply system further includes at least one of:
an unplanned component case notification device which provides a notice when the component case related information acquired from the component case related information acquisition device is different to planned component case related information; and
a mounting operation prohibition section which prohibits component mounting operation of a component mounter device provided with the bulk component supply system when the component case related information acquired from the component case related information acquisition device is different to the planned component case related information.
