Abstract

The present invention provides a conveyor device and a conveyor sensor capable of detecting various types of information on an object. The conveyor device that conveys the object to a predetermined conveyance place includes a conveyor sensor that detects the information of the object. The conveyor sensor includes a plurality of sensor members, and the plurality of sensor members can individually detect the presence of the object and is arranged side by side in a direction intersecting the conveying direction of the object.

First claim

The invention claimed is:

1 . A conveyor device that conveys an object to a predetermined conveyance place, comprising a conveyor sensor that detects information of the object,
the conveyor sensor including a plurality of sensor members each capable of individually detecting presence of the object, wherein the plurality of sensor members each has a light projecting unit and a light receiving unit, each of the light projecting unit tin light, each light receiving unit configured to receive light projected from one of the light projecting units that is reflected by the object, thereby detecting presence of the object at a predetermined place, and wherein the plurality of sensor members are lined up in a direction intersecting a conveying direction of the object.

2 . The conveyor device according to claim 1 , further comprising a first conveyance device that forms at least a part of a conveyance path of the object,
wherein the first conveyance device places the object on a conveyance surface to convey the object, and wherein the conveyor sensor is attached below the conveyance surface of the first conveyance device.

3 . The conveyor device according to claim 1 , further comprising a first conveyance device that forms at least a part of a conveyance path of the object,
wherein the first conveyance device includes a plurality of driving bodies arranged at an interval, the plurality of driving bodies placing the object on a conveyance surface over the driving bodies to convey the object, wherein the driving bodies includes a first and a second driving bodies, the first and the second driving bodies being adjacent to each other, and wherein the plurality of sensor members of the conveyor sensor are lined up between the first driving body and the second driving body.

4 . The conveyor device according to claim 1 ,
wherein the conveyor sensor executes a first detection operation of detecting one or more pieces of information selected from the group consisting of information on a posture of the object during conveyance and information on a conveyance position, and wherein one or more selected from the group consisting of a posture during conveyance and a conveying position are changed based on a result of the first detection operation.

5 . The conveyor device according to claim 1 , wherein the conveyor sensor executes a second detection operation of detecting information on dimensions of the object.

6 . The conveyor device according to claim 4 ,
wherein an extension member is provided above a side of the conveyance surface, and wherein when changing the posture of the object during conveyance, the object is conveyed toward the extension member, and the posture of the object is changed by pressing the object against the extension member.

7 . A conveyor sensor that is attached to a conveyor device conveying an object to a predetermined conveyance place and that detects information of the object, comprising:
a plurality of sensor members each capable of individually detecting presence of the object; and an outer member extending substantially linearly, wherein the plurality of sensor members each has a light projecting unit and a light receiving unit, each of the light projecting units projecting light, each light receiving unit configured to receive light projected from one of the light projecting units that is reflected by the object, thereby detecting presence of the object at a predetermined place, and wherein the plurality of sensor members are arranged on the outer member and are lined up in a longitudinal direction of the outer member.

8 . The conveyor device according to claim 2 ,
wherein the first conveyance device includes a plurality of driving bodies arranged at an interval, the plurality of driving bodies placing the object on a conveyance surface over the driving bodies to convey the object, wherein the driving bodies includes a first and a second driving bodies, the first and the second driving bodies being adjacent to each other, and wherein the plurality of sensor members of the conveyor sensor are lined up between the first driving body and the second driving body.
