Tire testing machine conveyor

摘要

A plurality of conveyors including a center conveyor are appropriately disposed without any gap or step and any interference between driving units. The center conveyor includes a pair of left and right belt driving pulleys that are provided at the front and rear sides in the conveying direction so as to stretch loop-shaped conveyor belts therebetween and are provided at both sides in the width direction, a pair of first left and right pulleys that is connected to each other through a connection shaft disposed on rotation axes of the belt driving pulleys at both outer sides in the width direction, a pair of left and right second pulleys that is provided below the first pulleys at both outer sides in the width direction so as to stretch loop-shaped pulley belts between the first and second pulleys and includes a common rotation axis, a driving shaft that is disposed on rotation axes of the second pulleys and is connected to the pair of second left and right pulleys, and a motor that is connected to an end of the driving shaft.

主权项

1. A tire testing machine conveyor that sends a tire to a center position of a spindle in a tire testing machine equipped with the spindle to which the tire to be tested is attached, the tire testing machine conveyor comprising:
a center conveyor that includes a pair of loop-shaped conveyor belts; and at least one of an entrance conveyor that is provided at the upstream side of the center conveyor in the conveying direction so that the downstream end is located between the pair of loop-shaped conveyor belts, and an exit conveyor that is provided at the downstream side of the center conveyor in the conveying direction so that the upstream end is located between the pair of loop-shaped conveyor belts, wherein the center conveyor includes:
a pair of sets of a belt driving pulley at the front side in the conveying direction and a belt driving pulley at the rear side in the conveying direction to stretch the loop-shaped conveyor belt therebetween;a pair of connection shafts provided on any one rotation axis of the belt driving pulleys at the front side in the conveying direction and of the belt driving pulleys at the rear side in the conveying direction common to both the pair of sets of a belt driving pulley at the front side and a belt driving pulley at the rear side so as to protrude both outer sides of the center conveyor in the width direction of the conveyor belt;a pair of first pulleys, each of the first pulleys being connected to each of the connection shafts;a pair of second pulleys, each of the second pulleys being provided below each of the first pulleys so that a loop-shaped pulley belt is stretched between the first and second pulleys, each of the pair of second pulleys including a common rotation axis;a driving shaft that is disposed on the rotation axis of the second pulleys and connects the pair of second pulleys to each other; anda driving unit that is connected to one end of the driving shaft.
