A transport device is capable of reliably determining a presence or absence of a lid provided on a container and/or determining detachment of the lid, with a simple configuration. The transport device transports a container that includes a lid on a side surface. The transport device includes a lid fall preventive member disposed so as to face an upper end of the lid of the container located in a transport position, and a lid detector that is disposed in the lid fall preventive member and detects the presence or absence of the upper end of the lid.
1. A transport device for transporting a container that includes a lid on a side surface, the transport device comprising:
a lid fall preventive member disposed so as to face an upper end of the lid of the container located in a transport position;
a lid detector that is disposed in or on the lid fall preventive member and detects a presence or absence of the upper end of the lid; and
a lifting driver that holds the container and raises or lowers the container; wherein
the lid fall preventive member is provided in or on the lifting driver; and
the lifting driver is moved in a lateral direction by a lateral protrusion mechanism.
2. The transport device according to claim 1 , wherein the lid detector is disposed so as to face a portion laterally apart from a center of the upper end of the lid.
3. The transport device according to claim 1 , further comprising a lid approach detector that detects an approach of the upper end of the lid.
4. The transport device according to claim 3 , wherein the lid approach detector is disposed so as to face a flat portion on the lid.
5. The transport device according to claim 1 , wherein the lid fall preventive member includes a stopper that comes into contact with a portion of the container except the lid to prevent the container from approaching.
