Abstract

The present disclosure provides a conveyance system and the like capable of preferably conveying a conveyed object in accordance with a state of the conveyed object. The conveyance system includes a conveyance robot, a drive controller, which is a controller, an image data acquisition unit, and a setting unit. The conveyance robot conveys the conveyed object. The drive controller controls an operation of the conveyance robot. The image data acquisition unit acquires image data obtained by capturing images of the conveyed object. The setting unit sets an operation parameter of the conveyance robot in the drive controller based on the acquired image data.

First claim

What is claimed is:

1 . A conveyance system comprising:
a conveyance robot for conveying a conveyed object; a controller configured to control an operation of the conveyance robot; an image data acquisition unit configured to acquire image data obtained by capturing images of the conveyed object; a storage unit configured to store a database for associating the image data of the conveyed object with an operation parameter of the conveyance robot; and a setting unit configured to set the operation parameter of the conveyance robot in the controller based on the image data of the conveyed object that has been acquired and the database.

2 . The conveyance system according to claim 1 , wherein
the database comprises a trained model that accepts the image data of the conveyed object as an input and outputs the operation parameter of the conveyance robot in accordance with the image data of the conveyed object that has been accepted, and the setting unit inputs the image data of the conveyed object into the trained model and sets the operation parameter, which is an output for the image data of the conveyed object that has been input, in the controller.

3 . The conveyance system according to claim 1 , wherein
the database stores each of reference image data of the conveyed object and the operation parameter that corresponds to the reference image data of the conveyed object in advance, and the setting unit compares the image data of the conveyed object that has been newly acquired with the reference image data stored in the storage unit and sets the operation parameter based on the result of the comparison.

4 . The conveyance system according to claim 1 , further comprising:
an image capturing unit configured to capture images of the conveyed object; and a wagon that accommodates the conveyed object and is moved by the conveyance robot in a state in which the wagon accommodates the conveyed object, wherein the setting unit acquires the image data of the conveyed object obtained by capturing images by the image capturing unit when the conveyed object is accommodated in the wagon.

5 . The conveyance system according to claim 4 , wherein
the wagon includes a data acquisition trigger configured to detect that the wagon has accommodated the conveyed object, and the setting unit acquires the image data of the conveyed object obtained by capturing images by the image capturing unit at a time back dated from the time when the data acquisition trigger has detected that the wagon has accommodated the conveyed object by a preset period.

6 . The conveyance system according to claim 4 , wherein
the conveyance robot comprises a raising/lowering mechanism for raising and/or lowering the wagon, and the setting unit sets a raising/lowering acceleration of the raising/lowering mechanism as the operation parameter.

7 . The conveyance system according to claim 1 , wherein the setting unit sets at least one of a moving acceleration of the conveyance robot and a moving path along which the conveyance robot passes as the operation parameter.

8 . The conveyance system according to claim 1 , wherein
the conveyance robot comprises an object sensor configured to detect an object that is present in the vicinity of the conveyance robot, and the setting unit sets a range detected by the object sensor as the operation parameter.

9 . The conveyance system according to claim 1 , wherein
the conveyance robot comprises a notification apparatus that sends a notification indicating that the conveyance robot is conveying the conveyed object to an area in the vicinity of the conveyance robot, and the setting unit sets a notification level of the notification apparatus as the operation parameter.

10 . A trained model generation method comprising:
a training data acquiring step for acquiring a plurality of pieces of training data, each of the pieces of training data comprising image data of a conveyed object and an operation parameter of a conveyance robot that corresponds to the image data of the conveyed object; and a model generation step for generating a trained model that accepts, using the training data, the image data of the conveyed object as an input and outputs the operation parameter of the conveyance robot in accordance with the image data of the conveyed object that has been accepted.

11 . A trained model learned by acquiring a plurality of pieces of training data, each of the pieces of training data comprising image data of a conveyed object and an operation parameter of a conveyance robot that corresponds to the image data of the conveyed object,
wherein the trained model causes a computer to execute processing of accepting the image data of the conveyed object as an input and outputting the operation parameter of the conveyance robot that conveys the conveyed object based on the image data of the conveyed object that has been accepted.

12 . A control method for setting an operation parameter in a conveyance robot for conveying a conveyed object, the control method comprising:
a storing step for storing a database for associating image data of the conveyed object with an operation parameter of the conveyance robot; an image data acquisition step for acquiring image data obtained by capturing images of the conveyed object; a setting step for setting the operation parameter based on the image data of the conveyed object that has been acquired and the database; and a control step for controlling the conveyance robot based on the set operation parameter.

13 . A non-transitory storage medium storing a program for causing a computer to execute a control method for setting an operation parameter in a conveyance robot for conveying a conveyed object, the control method comprising:
a storing step for storing a database for associating image data of the conveyed object with an operation parameter of the conveyance robot; an image data acquisition step for acquiring image data obtained by capturing images of the conveyed object; a setting step for setting the operation parameter based on the image data of the conveyed object that has been acquired and the database; and a control step for controlling the conveyance robot based on the set operation parameter.
