Abstract
A dishwashing system includes: a conveyor-type dishwasher that washes tableware in a washing machine main body while conveying the tableware by means of a conveyor; a robot device having a robot arm mechanism that is installed in the vicinity of a picking area outside of the washing machine main body in order to pick up tableware that is conveyed to the picking area by conveyors, and to transfer the tableware to a stock area; and a control device that generates an enabling signal relating to operations of the conveyors with respect to the dishwasher.
Claims22
A dishwashing system, comprising:
- a conveyor-type dishwasher that washes tableware in a washing chamber of a washing machine main body while conveying the tableware by means of a conveyor;
- a robot device including a robot arm mechanism that is installed in the vicinity of a picking area to pick up the tableware that is conveyed to the picking area from the washing chamber by the conveyor, and transfer the tableware to a stock area;
- and
- a control device that generates an enabling signal relating to operations of the conveyor with respect to the dishwasher.
A robot device, comprising:
- a robot arm mechanism that is installed in the vicinity of a picking area to pick up a work piece in the picking area and transfer the work piece to a stock area;
- a camera that photographs the picking area;
- an image processing section that processes an image of the picking area that is photographed by the camera, and determines whether or not the work piece is present, a kind of the work piece, a position of the work piece, and a posture of the work piece;
- a release position determining section that determines a release position on the stock area based on a kind of the work piece, and a number of stacked pieces of the work piece in the stock area;
- a picking operation control section that controls a picking operation by the robot arm mechanism based on the pick-up position and the release position;
- and
- an output section that, when the work piece is not present in the picking area or when a number of pieces of the work piece is equal to or less than a predetermined number, outputs a signal indicating that the work piece is not present in the picking area or that a number of pieces of the work piece is equal to or less than a predetermined number to an external device.
