Conveyor

Abstract

The present invention provides a conveying device capable of improving the positioning performance of a conveyed object with respect to a conveying direction. The conveying device (1) has: a conveying roller mechanism part (10), a plurality of conveying rollers (11), including a direction (A2) perpendicular to the axis relative to the conveying object ( B) the conveying rollers (11A, 11B) arranged obliquely in the conveying direction (A1); and the positioning belt mechanism part (20), the conveying object (B) is positioned by abutting against the belt linear part (21a), Wherein, the conveying roller mechanism part (10) is arranged such that a plurality of conveying rollers (11) are conveyed from a direction perpendicular to the axis with a larger inclination angle with respect to the conveying direction (11A) as they go from the upstream side to the downstream side. The roller group (11A) changes to the conveying roller group (11B) with a smaller inclination angle, and then changes to the conveying roller group (11C) in the direction perpendicular to the axis towards the conveying direction (A1), and, as the self-conveying The direction upstream side goes toward the downstream side, so that the roller surfaces of the plurality of conveying rollers (11) change from a smaller friction coefficient to a larger friction coefficient.

Description

technical field [0001] The present invention relates to a conveying device that moves a conveyed object in a conveying direction using a plurality of conveying rollers. Background technique [0002] Conventionally, as a conveying device using conveying rollers, a plurality of conveying rollers are arranged side by side in the conveying direction, and a conveying object placed on the conveying rollers is moved on the rotating conveying rollers. [0003] For example, Patent Document 1 describes conveying objects to be conveyed by using a group of roller conveyance members (conveyance rollers) arranged side by side at a predetermined angle with respect to the conveyance direction and a belt conveyance member running parallel to the conveyance direction. the conveying device.

Problems solved by technology

[0008] However, in the conveying device described in Patent Document 1, when the surface friction coefficient of the conveying roller is large, since the object to be conveyed is in contact with the belt conveying member, it is difficult to change direction in the conveying direction while sliding, When the surface friction coefficient of the conveying roller is small, even if the object to be conveyed is easy to change direction while sliding due to contact with the belt conveying member, it is difficult to maintain the orientation of the object to be conveyed in the conveying direction because it is easy to slide The object to be conveyed is conveyed in the state of the conveyance, and as a result, there is a problem that the positioning performance for the conveyance direction is degraded.
