A crank operating motor 21 is provided below the conveyor supporting frame 16, and the crank operating motor 21 allows the conveyor supporting frame 16 to swing up and down.

That is, a gear 22 is connected to an output shaft of the crank operating motor 21, and a gear portion 23 a of a crank 23 meshes with the gear 22. The upper end of a rod 24 linked to the other end of the crank 23 is connected to the lower surface of the conveyor support frame 16. When the motor 21 for crank operation is operated, the crank 23 is
The conveyor support frame 16 pivots about the central axis of a, and swings up and down around the horizontal swing axis 15.

The detection signal of the first sensor 50 provided at the unloading end of the inspection conveyor 12 is sent to the crank operating motor 21 so that the vertical sorting conveyor 13 can swing up and down.

A balancer 25 is connected to the lower surface of the conveyor support frame 16 adjacent to the rod 24 and urges the balancer 25 upward. A second sensor 51 is provided.

The left and right sorting station 5 has a pair of left and right and two upper and lower stages adjacent to the downstream side of the vertical sorting conveyor 13, that is, a total of four left and right sorting conveyors 26,.
The upper and lower two-stage right and left sorting conveyor 26 is configured as a stage conveyor.

The right and left sorting conveyor 26
Are a plurality of sprockets 28 provided on the base 27.
And a slat conveyor 30 that meshes with the sprocket 28. The slat conveyor 30 has a plurality of rows of chains that mesh with a pair of front and rear sprockets 28 along the carrying direction of the vertical sorting conveyor 13; It is constituted by strip-shaped steel slats 31 attached at intervals.

A drive motor 32 supported on a base 27 is connected to one end side of the sprocket 28 of each of the left and right sorting conveyors 26 in the upper and lower two stages and the left and right two rows. The slat conveyor 30 is made to travel around in the same direction as above.

The drive motor 32 is operated by a signal from a second sensor 51 provided at the end of the vertical sorting conveyor 13.

The right and left sorting conveyor 26 includes:
A transer unit 33 for distributing the panel W in the left-right direction (the direction perpendicular to the paper surface of FIG. 3) is provided.

The transer units 33 are provided above the right and left sorting conveyors 26 so as to correspond to the respective conveyors 26, and are slidable along the guide rails 34 of the base 27 in the direction perpendicular to the plane of FIG. In addition, there are provided a transa drive motor 35 for driving sliding and a payout member 36 for sending out the panel W.

Then, the dispensing member 36 is brought into contact with the inner side surface of the panel W, and the translator unit 33 is slid outward by the transer driving motor 35, thereby transporting the panel W in the left-right direction. Since the strips of the steel slats 31 of the right and left sorting conveyor 26 also extend in the left-right direction, the panel W is made of the steel slats 3.
1 smoothly slides on top.

The transer drive motor 35 is drivingly connected to a drive motor 32 for driving the conveyor 26 which is operated by the second sensor 51.
2 starts operation when the operation is stopped.

Next, the loading station 6 will be briefly described with reference to FIGS. 4 is a front view from the AA direction in FIG. 2, and FIG. 5 is a front view from the B direction in FIG.

As described above, the loading station 6 has four
Each loading station 6 is provided with the loading robot 7 and a pair of loading pallets 8 on the left and right sides of the loading robot 7.
, And a work positioning unit 37 is provided on the front of the loading robot 7.

Then, the work positioning unit 37
The right and left sorting conveyors 2 as shown in FIG.
6, the upper and lower sorting conveyors 26 are provided adjacent to the left and right sorting conveyor 26, respectively, and the lower conveyor is a belt conveyor. It is provided further outside than the work positioning portion 37 on the upper stage side via 38.

Then, each work positioning unit 3
Each of the slats 7 has a slat conveyor 40 and a plurality of positioning cylinder units 41 for positioning the panel W in two axial directions. Each positioning unit 10 is provided with a lift mechanism 42 as shown in FIG. 5 so that the loading pallet 8 is positioned in the height direction.

A method of distributing the panels W in the transport device having the above-described configuration will be described.

As shown in FIG. 6, the panel W sent out from the transfer press machine 2 is
And is sent to the vertical sorting conveyor 13.
(I)

During this time, for example, the vertical sorting conveyor 13
Is swinging upward as shown in the figure, and the belt drive motor 20 of the vertical sorting conveyor 13 is constantly running around. On the other hand, the drive motor 32 of the left and right sorting conveyor 26 is stopped both up and down.

When the panel W has passed the first sensor 50 at the end of the inspection conveyor 12 and a predetermined time has elapsed, the crank operating motor 21 starts to operate, and the downstream end of the vertical sorting conveyor 13 is turned off. Start the downward movement. On this occasion,
A part of the front end of the panel W faces the upper left / right sorting conveyor 26 (b).

Next, when the second sensor 51 detects the passage of the panel W, the drive motor 32 of the
Is operated, and the drive motor 32 is stopped after a predetermined time has elapsed. At this time, the panel W is divided into left and right conveyors 2
6, and then the transer drive motor 35 operates to pay out the panel W outward. During this time, the vertical sorting conveyor 13 oscillated downward
Above, the next panel W is accepted.

Next, such an operation is repeated. That is, the first sensor 50 that has detected the next panel W activates the crank operating motor 21 after a lapse of a predetermined time to start the swinging of the vertical sorting conveyor 13 and the panel W
Is detected, the drive motor 32 of the lower left / right sorting conveyor 26 operates for a certain period of receiving the panel W (d) to (e).

Then, the panel W
Can be alternately fed to the upper and lower left and right sorting conveyors 26, and the planar spread of the space of the entire apparatus can be suppressed.

The panels W delivered to the left and right by the transer unit 33 are sent to the slat conveyor 40 of the adjacent work positioning section 37 in the case of the upper stage, and via the belt conveyor 38 in the case of the lower stage. It is sent to the slat conveyor 40.

Although the second sensor 51 of this embodiment is provided at the discharge end of the vertical sorting conveyor 13, for example, other than the vertical sorting conveyor 13 such as the loading end of the vertical sorting conveyor 26, etc. May be provided at a plurality of locations.

In the embodiment, the conveyor 13 for vertical sorting is used.
Are formed in two upper and lower stages, but of course the stage conveyor is not limited to two stages. Also, the timing at which the first sensor 50 starts swinging the vertical sorting conveyor 13 or the second
The setting of the operation start and end times of the left and right sorting conveyor 26 by the sensor 51 is not limited to the embodiment.
