APRON CONVEYOR Russian patent published in 2017 - IPC B65G17/18 B65G17/34 B65G23/38 

FIELD: transportation.

SUBSTANCE: apron conveyor consists of plate bodies (6) mounted between a pair of a left and a right driving endless rotating bodies (5) by means of coaxial horizontal support shafts (7) and having a pair of a front and a rear guide rollers (8, 9) supported by guides (21, 23) resting on each of the upper and lower horizontal segments (1, 2) of the track. A guide means (25, 26) of the U-shaped turn at both ends consists of guide rollers (8, 9), a rotary body (27, 28) controlling the position of the plate body, and a driving means for the rotary body. The rotary body (27, 28) has a rotation radius, the same as the rotation radius of the horizontal support shaft (7) on the U-shaped track turn segments (3, 4), and comprises an engaging portion for positioning and rotating the guide rollers (8, 9). The drive means drives the rotary body (27, 28), so that the engaging portion rotates in one direction and at a speed same as the rotation speed of the horizontal support shaft (7) on the U-shaped track turn segments (3, 4).

EFFECT: simplifying the guide means of the U-shaped turn, reducing the apron conveyor width.
