[Problems to be solved by the device]

 However, in the above-mentioned conventional intermediate unloading device for a conveyor, as is clear from FIG. 6, which of the left and right sides of the conveyor 2 is the mounting position of the rotary shaft 6 for supporting the rotary frame 4 horizontally rotatable. Therefore, the unloading direction is fixed to either the left side or the right side of the conveyor 2. Therefore, when it is necessary to unload the conveyed product 1 at the same position on the conveyor 2 on both left and right sides, this device cannot be used.

Further, when it is attempted to carry out the invention, it is conceivable to arrange the left side and the right side of the above-mentioned conventional device by shifting the positions back and forth along the transfer line of the conveyor 2. However, in this case, in order to adjust the unloading position, it is necessary to bend the unloading chute 11 connected to the unloading section to align the final unloading position with a straight line. In order to move the chute 11, it is necessary to secure a continuous curved surface and inclination, and there is a problem that the degree of freedom is lost due to the installation height of the conveyor 2, the arrangement of the conveyor 2, and the like.

The present invention has been made in order to solve the problems of the above-mentioned conventional apparatus, and a single apparatus having a simple structure can convey a product to the left or right side of the conveyor at the same position in the longitudinal direction of the conveyor. The purpose is to provide an intermediate unloading device for a conveyor that can unload items.

[0008]

[Means for Solving the Problems]

 According to the present invention, there is provided a support post provided on one left and right side in the middle of a longitudinal direction of a conveyor, and a first end whose one end is horizontally rotatably supported by the support post at a required distance from an upper surface of the conveyor. A frame, a second frame whose one end is horizontally rotatably supported on the other side of the first frame, and a second frame which is attached to the lower side of the second frame with a length that diagonally crosses the conveyor. Further, the present invention relates to an intermediate unloading device for a conveyor, comprising: a guide conveyor having, on both sides, a conveying surface perpendicular to the upper surface of the conveyor.

[0009]

[Action]

 When the goods on the conveyor are not unloaded in the middle, the first frame, the second frame, and the guide conveyor are moved outside the conveyor so that they are parallel to the conveyor direction.

When unloading the conveyed product on the conveyor to the left and right sides of the conveyor, the first frame and the second frame are aligned so as to overlap each other when seen in a plan view. Rotate the guide conveyor so that the guide conveyor extends diagonally across the conveyor direction. Then, the goods conveyed by the conveyor are unloaded on the left and right sides of the conveyor due to the conveying force of the conveyor and the conveying action of the conveying surface on one side of the guide conveyor.

In addition, when unloading the conveyed product on the conveyor to the other side of the conveyor, the second frame is rotated while the first frame is parallel to the longitudinal direction of the conveyor to rotate the guide conveyor. Extends over the conveyor so that it crosses the conveyor direction diagonally in the opposite direction. Then, the goods conveyed by the conveyor are unloaded on the left and right sides of the conveyor line by the conveying force of the conveyor and the conveying action of the conveying surface on the other side of the guide conveyor.

With the above, a single device can freely unload conveyed articles at the same position on the way of the conveyor, in either the left or right direction of the conveyor.
