Description

A Direction Conversion Conveyor

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyor that is disposed in a section connecting a linear conveyor and another linear conveyor and safely switches the conveying direction of the conveyed material at a high speed.

Generally, a conveyor for conveying a product (hereinafter referred to as a conveyor) is a device for conveying an article automatically or continuously between a certain distance, and uses a belt, a trolley or a roller as a conveying medium.

Such a conveyor is provided with various kinds of means for conveying articles between predetermined sections, and the most general form can be classified into a belt-type conveyor and a roller-type conveyor.

These are known as a linear or curved conveyor for placing an article to be conveyed on the upper surface of the conveyor and conveying the article linearly or curvilinearly on a plane, and a bellows-type conveyor that is stretchable in the longitudinal direction.

That is, the linear conveyor is formed in a straight shape in one direction, and its shape is simple, so that it is easy to install a power transmission device and is installed in a general automation line.

The curved conveyor is mainly used to efficiently use the inner space by connecting a curved conveyor to a linear conveyor that linearly transfers the logistics in a case where the internal space of the factory building is narrow or when the conveying direction is changed.

The bellows type conveyor is stretched in the longitudinal direction. When the bellows type conveyor is not used, the bellows type conveyor is folded and stored. When necessary, the bellows type conveyor is used in a longitudinal direction so that the conveyor installation space can be used for other purposes.

In Patent Document 1, a hexagonal belt connected with a motor pulley is connected to a snap roller having a groove with a downward light and a guide roller, and a radial carrier roller and a hexagonal belt having different inner and outer diameters are brought into contact with each other. And conveys a curved conveyor that conveys the logarithm along the curve by rotating it.

However, when a curved conveyor is disposed between the linear conveyor and another linear conveyor to transfer the logistics as a conveying object in one direction, if the rotation speed of the roller is increased to increase the overall amount of logistics through the increase of the logistics transfer amount per unit time, The centrifugal force generated when the logistics that is transported at a high speed from the linear conveyor to the curved conveyor side is changed while passing through the curved conveyor is increased in proportion to the conveying speed.

Accordingly, the material passing through the curved conveyor can be turned over to fall on the curved conveyor and enter the entrance of the other linear conveyor, or fall off to the floor as it goes beyond the curved conveyance trajectory of the curved conveyor.

Particularly, in the case of conveying a large volume or a high-height logistics at a high speed, the conveyance failure of the curved portion conveyance locus of the curved conveyor causes the logistics to deviate from the locus by the centrifugal force, It stopped the transfer operation and decreased the efficiency of the logistics transfer operation.
