DETAILED DESCRIPTION OF THE INVENTION

[Object of the invention]

[0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyor turn roller device which is mounted near a crossing portion when two conveyors are crossed and connected.

[0003]

2. Description of the Related Art Conventionally, when a conveyed object is conveyed in a direction other than a linear direction, for example, a conveyor in which two conveyors are connected vertically is used. Then, at a portion where the frames of the conveyors intersect, a turn roller device is attached to both conveyors so as to be slidable along the center of the angle of each conveyor, that is, along an angle of about 45 °. , The turn roller device is slid.

[0004]

However, in the case of the above-mentioned conventional apparatus, it merely slides along the center of the angle between the conveyors, and sufficient fine adjustment cannot be performed. That is, when the widths of the two conveyors are different, the center of the roller must be located other than on the central extension line of the angle.

[0005] Further, since the turn roller device is mounted over the two conveyors at the position where the conveyors are connected to each other, if the connection angle between the conveyors is different, the device itself must be changed, which leads to versatility. Has a scarce problem.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a versatile conveyor turn roller device capable of performing sufficient fine adjustment.
