A truck rail 12 is provided. Both ends 12a of the truck rail 12 are inclined downward, and the distance between the inclined ends 12a is equal to that of the main wheels 9, 9.
It is set narrower than the pitch between.

The reversing drive device 3 includes a reversing lever 4 and a supporting shaft 1
It is supported so as to be vertically rotatable about three directions, and is rotationally driven in the forward and reverse directions by a drive source 15 such as a hydraulic cylinder via a link 14, and a supporting roller 26 is installed at the tip of the rotating arm 4. . Three reversing levers 4 are provided in parallel on the reversing carriage 2 so as to be located below the respective vertical frame members 8a, and these three are coupled to each other and are integrally driven to rotate. The support roller 26 of each reversing lever 4 can roll inside each vertical frame member 8 a made of an outwardly grooved member of the reversing carriage 2.

The carriage returning device 7 is one in which the hook member 6 is attached to a chain 16 which is an endless winding member.
The chain 16 is driven along the inside of the truck rail 12 in a guide groove 17 (FIGS. 2 and 4) provided in the main body frame 1. The traveling drive of the chain 16 is performed by rotating one of the sprockets 18 provided at both ends by a drive device (not shown) such as a motor.

The hook member 6 has an upward engaging groove 6a into which the axle 9a of the main wheel 9 of the reversing carriage 2 is fitted, and the depth of the engaging groove 6a is such that the reversing carriage 2 is at both ends of the carriage rail 12. Part 1
The axle 9a is formed to a depth such that the axle 9a does not come off even if it is moved vertically due to the inclination of 2a. Further, the hook members 6 are arranged at a pitch between the main wheels 9 of the reversing carriage 2 and three hook members 6 are provided on the chain 1.
It is attached to 6.

As shown in FIG. 3, the pedestal 5 includes three inclined guide rails 19 and each vertical frame member 8a of the reversing trolley 2.
The guide rails 1 are provided in parallel at a pitch of
The lower part of 9 is curved in an arc shape. These guide rails 19 are formed of groove-shaped members on which the guide rollers 10 of the reversing carriage 2 are loosely fitted and roll, and the bottom surface of the groove forms the carriage guide surface 1.
9a is constructed.

The central guide rail 19 is composed of a movable rail 21 whose upper portion is rotatable around a support shaft 21, and the movable rail 20 is provided with an internal return spring by an air cylinder 23 installed in a cradle main body 22. By this, it is urged to project to a predetermined angle in a forward leaning posture. The ports of the cylinder chambers on both sides of the piston of the air cylinder 23 are open to the atmosphere via the throttle valves 24, respectively. Near the upper ends of the guide rails 19 on both sides, shock absorbers 25 for abutting the reversing carriage 2 are attached.

The operation of the above configuration will be described. Panel P is
It goes into the reversing carriage 2 on the roller conveyor 11 and is stopped at a fixed position by stopping the driving of the roller conveyor 11 by detecting it with an appropriate detection switch.

After the stop, the reversing lever 4 is rotated upward to lift the panel P together with the reversing carriage 2, and the reversing carriage 2 is reversed to the leaning state on the cradle 2 as shown by the chain line in FIG. A)). At this time, the reversing carriage 2 has the main wheels 9
The axle 9a is engaged with the hook 6 on the pedestal 5 side and stably rotates about the hook 6 as a fulcrum.

Before the reversing carriage 2 is received by the cradle 2, the central guide roller 10 first contacts the movable rail 20 projecting forward as shown in FIG.
The shock is absorbed by the damping effect of the throttle valve 24. Therefore, the impact sound is eliminated, and the panel P is prevented from being damaged by being impacted in the reversing carriage 2. After that, the shock absorber 25 also absorbs the shock, so that the shock noise is more reliably prevented.

When the reversing carriage 2 leans against the cradle 2, the chain 16 is driven and the hook 6 receiving the reversing carriage 2 moves to the other end side of the main body frame 1. Along with this, as shown in FIG.
When the reversing carriage 2 moves to its original position while slipping along the guide rails 19 of 1, the chain 16 stops traveling and the reversal is completed. In this way, the inversion carriage 2 can be stably inverted from the pedestal 2 to the tilted state while being supported by the hooks 6.

When the hook 6 is moved, the main wheels 9a of the reversing carriage 2 are inclined end portions 12a of the carriage rails 12a.
It moves up slightly from the middle part to the middle part. Therefore, the panel P in the reversing carriage 2 is prevented from interfering with the roller conveyor 11. At the completion of the reversal, the front and rear main wheels 9 have the downwardly inclined end portions 12 of the truck rail 12.
Since it is placed on a, the reversing carriage 2 is slightly lowered, and the panel P in the reversing carriage 2 is lowered onto the roller conveyor 11. In this way, the panel P, which has been completely inverted, is carried out by the roller conveyor 11.

In this panel reversing machine, the panel P is
Is provided with a flat-shaped reversing carriage 2 which can be received. The reversing carriage 2 is lifted up by the reversing lever 4 to lean on the cradle 2, and then the reversing carriage 2 is slid along the cradle 2.
Since it is configured to be returned to the main body frame 1, the structure is simple and can be designed compactly. Moreover, unlike the conventional drum type, it is not necessary to perform idle rotation after completion of reversal, the next reversal can be started immediately, and reversal can be performed efficiently. Further, as compared with the conventional drum type, the receiving height to the reversing carriage 2 can be designed to be low, so that it is not necessary to provide a pit or the like and the installation work can be easily performed. Furthermore, unlike the conventional example of FIG. 10, the panel P
Will never turn upside down after being flipped.

Although the carriage returning device 7 is composed of the hook member 6 and the chain 16 in the above embodiment, various other structures can be adopted. Further, both ends 12a of the carriage rail 12 do not necessarily have to be inclined, and for example, the roller conveyor 11 may be moved up and down to avoid interference when the panel P is inverted.

[0031]

The panel reversing machine of the present invention is provided with a flat-shaped reversing carriage capable of receiving panels and the like. The reversing carriage is lifted from the main body frame to lean on the trolley guide surface of the pedestal, and thereafter. Since the inversion carriage is configured to return to the main frame while sliding along the pedestal, the structure is simple and the design can be made compact, and it is not necessary to perform idle rotation after completion of inversion, and inversion can be performed efficiently. . In addition, it can be designed with a low receiving height to the reversing cart,
