BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a component supply apparatus according to an embodiment of the present invention.

FIGS. 1 to 5 show the configuration of an embodiment of the present invention. In FIG. 1, a double-arm robot 2 is provided upright at the upper center of the apparatus main body 1, and four tray positioning members 3 are provided on both sides of the double-arm robot 2 on the upper surface of the apparatus main body 1. Have been. A work table 4 is provided on the apparatus body 1, and an operation panel 5 is mounted on the front. Further, a transparent cover 6 is provided on the front surface and both side surfaces of the mounting main body 1. Further, a supply lift 7 and a buffer lift 8, which will be described later, are provided at the rear of the apparatus main body 1. Four magazines 9 are placed on the lifts 7, 8 vertically and horizontally.

FIGS. 2 to 5 show the detailed structure of the positioning member 3 and the lifts 7, 8. FIG. As shown in FIGS. 2 and 3, two supply lifts 7 are provided on the left and right sides on the rear side of the apparatus main body 1, two each in the vertical direction, and the four supply lifts 7 a, 7 b, 7 c, 7 d 7a and 7b are driven up and down by one servo motor as a set, and 7c and 7d are driven up and down by another servo motor as a set. Each supply lift 7 is provided with a plurality of pairs of rollers 11 that are rotatable. Magazines 9a and 9
b, 9c and 9d are movably mounted. Two buffer lifts 8 are provided in the vertical direction on the left and right sides behind the supply lift 7, respectively. Of the four buffer lifts 8a, 8b, 8c and 8d, 8a and 8b are provided as one set. The cylinders 8c and 8d are driven up and down by another cylinder (not shown) by a cylinder (not shown). A plurality of pairs of rollers 12 are rotatably provided on each buffer lift 8, and magazines 9a, 9b, 9c, and 9d can move on the rollers 12, respectively.

As shown in FIG. 3, four positioning members 3 are provided on both sides of the dual-arm robot 2 on the apparatus main body 1, one each in the front-rear direction, and the supply lifts 7 a, 7 b, 7 are provided.
Magazines 9a, 9 sent from c, 7d respectively
trays 21a, 21b, 21c, 2 in b, 9c, 9d
1d are positioning members 3a, 3b, 3c, 3d, respectively.
It is to be positioned and mounted on top. Each positioning member 3 is provided with a cylinder 13a, 1
It is driven up and down by 3b, 13c and 13d. That is, as shown in FIGS. 4 and 5, the rotation of the pinion 15 meshing with the rack 14 linearly moved by the cylinder 13 drives the positioning member 3 up and down via the crank mechanism 16, and the tray withdrawal height L and Tray positioning height H
And move up and down.

Next, the operation of this embodiment will be described with reference to FIGS. For example, when there is a request for the part A from the assembling machine, the external automatic guided vehicle or the worker unloads the empty magazine 9a of the part A on the unloading buffer lift 8b. Next, the loading buffer lift 8a is lowered to the height of the automatic guided vehicle, and the magazine 9 having the tray in which the parts A are stored is provided.
a is moved onto the buffer lift 8a.

When the magazine 9a on the supply lift 7a, which is currently supplying components, is empty, the empty magazine 9a is unloaded onto the unloading buffer lift 8b, and the unloading magazine 9a is loaded with the new magazine 9a. The buffer lift 8a is moved to the height of the supply lift 7a, and a new magazine 9a is loaded on the supply lift 7a. The tray 21a in the magazine 9a on the supply lift 7a is pulled out onto the tray positioning member 3a by a hook (not shown). The tray 21 a pulled out is a sensor 22 provided on the apparatus main body 1 on the way.
To detect the type and confirm that it is a correct part.

After the confirmation, the tray 21a is pulled out to the position of the tray positioning member 3a, and the cylinder 13b raises the tray from the tray drawing height L to the tray positioning height H for positioning. The ascending speed at this time changes according to a sine curve so that no impact is applied to the parts. During this time, the tray 21b on the positioning member 3b is still positioned at that position. When the magazine 9a on the supply lift 7a becomes empty, the above operation is repeated.

According to the present embodiment, four types of components can be supplied in a small space, and the types of components that can be supplied by one robot 2 are increased, and equipment costs are reduced. Further, by providing the buffer lift 8 in the magazine supply unit, the supply of the magazine 9 by the automatic guided vehicle becomes possible.
Further, since the positioning member 3 moves up and down, the tray 21a can be replaced even during the positioning of the tray 21b. Further, the type of the component on the tray 21 can be confirmed by the sensor 22, and the supply of the component can be prevented.

In the above embodiment, the exchange of the magazine 9a has been described. However, exchange of the other magazines 9b, 9c, 9d can be performed in the same manner. Also, a plurality of pairs of rollers 1
1 and 12 may be ordinary conveyors.

[0018]

As described in the foregoing, according to claim 1 wherein
According to the component supply device described in Item 3 , the magazine is exchanged via the buffer lift and the supply lift, and the magazine is transferred on the tray positioning member, so that four types of components can be supplied in a small space. As a result, it is possible to improve work efficiency and reduce equipment costs. In addition, since the positioning member can be moved up and down, another tray can be replaced while one tray is being positioned. In addition, magazines can be supplied by automatic guided vehicles.

According to the fourth aspect of the present invention, since the detecting member for detecting the type of the component on the tray is provided on the apparatus main body, erroneous supply of the component can be prevented.
