Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the relay of a board when transferring a board between a magazine for accommodating a plate-like member (hereinafter, referred to as a board) such as a printed board and a transfer device for transferring the board. The present invention relates to a circuit board relay device.

BACKGROUND ART FIG. 3 shows a conventional example of such a board relay device. As shown, a magazine 2 for accommodating a plurality of substrates 1 is usually
The substrate 1 is carried by a lifting device (not shown) in the vicinity of the transport device 3 for transporting the substrate 1. The magazine 2 is formed so that the substrates 1 can be stored in a stacked manner at predetermined intervals in the vertical direction.
Can be moved up and down.

A substrate relay device that relays the transfer of the substrate between the magazine 2 and the transport device 3 includes a substrate moving mechanism (not shown) that moves the substrate 1 between the magazine 2 and the transport device 3. A guide member 4 for guiding the substrate 1 which is fixed and moved. As the substrate moving mechanism, for example, a mechanism for moving a claw member (not shown) engaging with the substrate by power of an air cylinder (not shown) or the like and moving the substrate 1 is known.

As described above, in the conventional board relay device, since the guide member 4 is fixedly mounted between the magazine 2 and the transport device 3 in an immovable state, when the board moves, the guide member 4 is located below the tip of the board 1 in the moving direction. The edge is caught by the transport device 3 or the magazine 2, and there is a problem that smooth substrate relay is hindered. In particular, in relaying a substrate from the transport device 3 to the magazine 2, the relative position of the guide member 4 and the magazine 2 in the vertical direction changes, so that the positional relationship between the guide member 4 and the substrate storage portion of the magazine 2 varies. It was large and the above-mentioned inconvenience occurred and it was won.

SUMMARY OF THE INVENTION In view of the above, an object of the present invention is to provide a board relay device capable of achieving highly reliable board relay.

In the substrate relay device according to the present invention, a guide member for guiding the substrate between the magazine and the transfer device is swingably provided, and the guide member is swung so that the leading end side of the guide member in the moving direction of the substrate becomes higher. It is characteristic.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 schematically shows a board relay device according to the present invention. In the figure, the same components as those in FIG. 3 are denoted by the same reference numerals, and description thereof is omitted.

As shown in FIG. 1, in the substrate relay device according to the present invention, the guide member 14 disposed between the magazine 2 and the transport device 3 is swingable in a direction perpendicular to the moving direction of the substrate 1. It is provided, and in the figure, it is swingable about the shaft 6. The guide member 5 has a guide surface 5a in contact with the bottom surface of the substrate 1, and guides the substrate 1 on the guide surface 5a.
The guide member 5 is swung by a driving means described later so that the leading end side of the guide surface 5a in the moving direction of the substrate 1 becomes higher. That is, as shown in FIG. 1 (a), when the substrate is transferred from the magazine 2 to the transport device 3, the guide surface 5a is higher on the transport device side than on the magazine side. As shown in b), when the substrate is transferred from the transport device 3 to the magazine 2, the guide surface 5a is higher on the magazine side than on the transport device side.

FIG. 2 shows the board relay device according to the present invention in detail. As shown in FIGS. 2 (a) and 2 (b), a pair of guide members 5 are provided symmetrically with respect to the moving direction of the substrate 1,
It is swingable about the shaft 6. The shaft 6 is a support member 7
The supporting members 7 can adjust the distance between each other. The support member 7 carries a knock cylinder 8 for swinging the guide member 5, and the knock cylinder 8 is covered by a cover 9.

As shown in FIGS. 2A and 2B, the right and left side mechanisms have the same configuration as shown in FIGS. 2A and 2B. Therefore, the left side mechanism will be described in detail here. As shown in FIGS. 2 (c), 2 (d) and 2 (e), the guide member 5 has a columnar projection 10 projecting from the shaft 6. A pressing member 12 carried by a push rod 11 of the knock cylinder 8 is in contact with the projection 10. The pressing member 12 presses the projection 10 together with the push rod 12 downward according to the air pressure or the like supplied to the knock cylinder 8 to swing the guide member 5. Also, protrusion 10
Is urged upward by a return spring 13. When the pressing force of the knock cylinder 8 stops acting on the projection 10, the projection 10 is pulled back upward by the return spring 13, and the guide member 5 swings about the shaft 6. They are hurried. That is, the knock cylinder 8 and the return spring 13 act as driving means for swinging the guide member 5. In addition, a cam mechanism can be used as the driving means.

The configuration other than the above-described configuration, that is, the mechanism for moving the substrate 1 between the magazine 2 and the transport device 3 is the same as that of the conventional example, and therefore, the description is omitted.

Effect of the Invention As described above, in the substrate relay device according to the present invention, the guide member provided between the magazine and the transport device so as to be swingable is swung by the driving means, and the moving (progressing) direction of the substrate. In this configuration, the guide surface of the guide member can guide the substrate at an appropriate angle of attack with respect to the movement of the substrate in any of the two directions. Therefore, the lower edge of the front end of the substrate in the moving direction is not caught by the magazine or the transport device, and a highly reliable substrate relay is achieved. In particular, when the substrate is relayed from the transport device to the magazine, it is possible to absorb an error in the accuracy of the elevating interval of the elevating device that elevates the magazine at predetermined intervals.
