Only the frame transport mechanism 51 will be explained.
The first hopper 50 of the first frame transport mechanism 51 is located at the left outer position of the panel transport path, and the second hopper 100 of the second frame transport mechanism 101 is located at the right outer position of the panel transport path. It is located in the opposite direction.

As shown in FIG. 3, a large number of side frames 1 are supplied to the first hopper 50 of the first frame conveyance mechanism 51 in a predetermined number of bundles by a supply belt conveyor 52. It's getting old.

A group of side frames supplied into the hopper 50 are arranged to gather at the front of the hopper 50 along the inclined bottom plate 50A of the hopper 50. A group of side frames gathered at the front of the hopper 50 are sequentially conveyed upward by a first conveyor belt 53 running inside the hopper 50. The belt conveyor 53 has a pair of pulleys 54a, 5
4b in a closed loop. A large number of protrusions 55 for locking side frames are formed on the surface of the belt conveyor 53 at equal intervals in the longitudinal direction. The side frames 1 are transported upward one by one as the second frame portions 1B fit into the protrusions 55.

As shown in FIG. 3, the second frame portion 1B of the side frame 1 is located at the outer position on both the left and right sides of the first conveyor belt conveyor 53 at the corner portion between the ridge portion 55 and the surface of the belt conveyor 53. A pair of drop plates 56, 56 are arranged to return this side frame 1 back into the hopper 50 when it is fitted into the hopper 50.
That is, when the second frame portion 1B of the side frame 1 is fitted into the corner portion as described above, the bulges 1b, 1 formed on the second frame portion 1B
b protrudes toward the side where the drop plates 56, 56 are disposed at outer positions on both the left and right sides of the first conveyor belt conveyor 53. When the side frame 1 is conveyed in this state, the bulging portions 1b, 1b abut on the dropping plates 56, 56, respectively, and the side frame 1 is dropped into the hopper 50 while being turned over. Note that the side frame 1, which could not be dropped into the hopper 50 even by the drop plates 56, 56, is placed near the upper pulley 54a that drives the first conveyor belt 53. A pair of dropping rods 57, 57 for scraping up and dropping securely into the hopper 50.
are arranged at outer positions on both left and right sides of the belt conveyor 53.

Further, the bottom plate 50 is attached to the bottom of the hopper 50.
An optical sensor 58 is arranged so as to face the through hole 50a opened at A. The optical sensor 58 detects the presence or absence of the side frame 1 in the hopper 50.
When all are conveyed, the supply belt conveyor 52
When a bundle of side frames 1 is fed into the hopper 50, a stop signal is sent to the drive unit.

The side frame 1 conveyed by the first conveyor belt conveyor 53 is parallel to the upper position of the panel conveyance path of the panel P so as to cross the panel conveyance path, as shown in FIGS. 4 and 5. The panels are sequentially sent out to the right side of the panel conveyance path along a pair of second conveyor belt conveyors 59, 59 disposed in . When the side frame 1 comes to the delivery end position of each of the belt conveyors 59, 59,
The side frame 1 is received and supported by a stopper plate 60 provided at the delivery end position, and the presence of the side frame 1 is detected by an optical sensor 61. As a result, the relay belt conveyor 63, which is wound around the pair of pulleys 62, 62 in a closed loop, enters between the belt conveyors 9, 9 by means of the piston/cylinder section 64, which uses air pressure as a driving source. As a result, the side frame 1 located at the delivery end of each of the belt conveyors 59, 59 is connected to the relay belt conveyor 63.
The panel P is sent out in the same direction as the conveyance direction of the panel P, and is conveyed above the first frame mounting position by the third conveyor belt conveyor 65, which is arranged parallel to the right upper position of the conveyor roller conveyors 9, 9. Ru.

Two pairs of frame conveyance control pins 66, 67, 66, 67 for conveying the side frames 1 one by one at a predetermined interval are located near the feed end of each of the second conveyor belt conveyors 59, 59. It is provided so as to be able to rise and fall freely with respect to the second conveyor belt conveyor.

The frame conveyance control pins 66 and 67 are the sixth
As shown in the figure, the front control pin 66 on the forward side of the feedout
is connected via a link 68 so as to perform a so-called see-saw movement in which a rear control pin 67 on the rear side of the feeder moves upward when the feeder is lowering.

As shown in FIG. 7, when the leading side frame 1 is supported by the stopper plate 60, the front control pin 66 is lowered, and the second side frame 1 of the next side frame 1 is lowered.
The side frame portion 1B comes into contact with the upper surface of the side frame portion 1B and engages with the bulge portion 1b, thereby stopping the feeding of the next side frame portion 1. At this time, the second conveyor belt 5
9 continues to run, and the subsequent side frames 1 including the next side frame 1 are connected to the belt conveyor 5.
9 and slips.

Then, as shown in FIG. 8, when the leading side frame 1 is sent out by the relay belt conveyor 63, the front control pin 66 goes up and the rear control pin 67 goes down. As a result, the next side frame 1 is sent out by the second conveyor belt 59. When the next side frame 1 is supported by the stopper plate 60 as shown in FIG.
comes into contact with the upper surface of the second frame portion 1B and engages with the bulge portion 1b, thereby stopping the feeding of the side frames 1 one after another. At this time, the second conveyor belt 59 continues to run, and the subsequent side frames 1 including the successive side frames 1 are in a state of slipping on the belt conveyor 59. In this way, the optical sensor 61 detects the presence or absence of the side frame 1 at the delivery end position of the second conveyor belt conveyor 59, 59, and controls the two pairs of frame conveyance control pins 66, 67, 66, 67. By driving, the side frames 1 can be transported one by one.

Note that the second conveyor belt conveyor 59,5
An optical sensor 69 for controlling the drive of the first conveyor belt conveyor 53 is provided in the middle of the conveyance path of the side frame 1 by the conveyor belt 9 . The optical sensor 69 detects when the side frame 1 is in large numbers on the second conveyor belt conveyor 59 and when the projection of light is blocked for a long time,
A stop signal is sent to the drive source to stop the conveyance of the side frame 1 from the first hopper 50.
