In this carton reversing conveyance device, a pair of arms perpendicular to the conveying conveyor are engaged with the reversing frame, and a carton support plate is provided at the center of the arms, and when the reversing frame is in a resting state, the above-mentioned arms are engaged with the reversing frame. The present invention is characterized in that one of the lower sides of the 1-ton support plate is configured to be at the same height as the 1.2 conveyor.

(Example) The present invention will now be described in detail with reference to the illustrated embodiments.

1 and 2 show a plan view and a side view of a carton reversing and conveying device according to the present invention, and FIG. 3 shows a perspective view of a main part of the device.

In the figure, 1 is a first conveyor, and 2 is a second conveyor. They each consist of a pair of parallel conveyors, and are connected by a rod 3.4, and rotate synchronously according to a motor 5.6. It is something to do. A reversing frame 7 is provided on the outside of the first conveyor 1 and the second conveyor 2, and the reversing frame 7
．． It has a central axis on the central vertical line of the two conveyors and perpendicular to the conveyors, and is configured to freely rotate in the conveyor traveling direction. And inverted frame 7
A sprocket 8 is attached to each of the wheels, and the sprocket 8 is connected to a sprocket 8' attached to the rotating shaft of the motor 9 via a chain IO. Further, the two sprockets 8' are connected by a rod 11 extending from the rotating shaft of the motor 9, so that the pair of reversing frames 7 are configured to rotate synchronously.

On the other hand, the reversing frame 7 is provided with a through hole including the central axis, and a stopper 12 that freely moves in and out on the central axis through this hole and a cylinder 13 that operates the stopper 12 are arranged.

Further, in each of the reversing frames 7, a pair of arms 14, which are perpendicular to the first and second conveyors, are arranged at equal intervals from the central axis in a pair of upper and lower positions. 15'. At the center of each arm 14 is a first
, 2 transport conveyor L 2) is provided with a carton support plate 16 = 4-, and in a stationary state, one of the lower sides of the carton support plate 16 is in the same direction as the 1.2 transport conveyor 1.2. It is configured to have a height. The carton support plate 16 has a first conveyor 1 side and a second conveyor 2 side.
Four openings and -ra 17 are arranged on each side.

On the other hand, the reversing frame 7 is attached to the frame support plate 18 (third
(not shown in the figure) to a support stand 19, and the support stand 19 is fixed to a base 21 of the reversing conveyance device by a locking member 20.

The support stand 19 and the locking member 20 are connected via a threaded adjustment rod 22, so that the height of the support stand 19 with respect to the base 21 can be freely adjusted. It is configured.

Next, the operation of the carton reversing conveyance device having the above-described configuration will be explained.

As shown in FIG. 3, the cartons to be palletized are transferred by the carry-in conveyor 23 in the direction of the arrow, and the carton positioning guide 2 installed at the end of the carry-in conveyor 23
4 until the center of the conveyor contacts the stopper 12, and in that state a sensor (not shown) is activated to start the motor 9. The rotation of the motor 9 rotates the sprocket 8 via the chain 10, and the reversing frame 7 begins to rotate about the central axis on the fixed frame support plate 18.
