Conveyance system
A conveyance system which improves the stability of a mounting base raised and lowered along a guide rail is achieved. A conveyance system according to an embodiment of the present disclosure includes a mounting base with a groove guided along a guide rail extending in a vertical direction and a lifting mechanism configured to raise and lower the mounting base. When a direction of a movement of an item to be carried out from the mounting base is defined as a forward direction and a direction opposite to the forward direction is defined as a rearward direction, the conveyance system raises and lowers the mounting base while pressing a side surface on a rear side of the groove against the guide rail.
1 . A conveyance system comprising:
a mounting base with a groove guided along a guide rail extending in a vertical direction; and
a lifting mechanism configured to raise and lower the mounting base, wherein when a direction of a movement of an item to be carried out from the mounting base is defined as a forward direction and a direction opposite to the forward direction is defined as a rearward direction, the mounting base is raised and lowered while pressing a side surface on a rear side of the groove against the guide rail, wherein
the side surface on the rear side is pressed against the guide rail using an actuator, and
the higher a height of the mounting base, the greater a force exerted by the actuator.
2 . The conveyance system according to claim 1 , wherein the heavier the item mounted on the mounting base, the smaller the force exerted by the actuator.
3 . The conveyance system according to claim 1 , further comprising a control unit configured to control the actuator in such a way that the force for pressing the side surface on the rear side against the guide rail falls in a predetermined range.
4 . The conveyance system according to claim 1 , further comprising a sensor configured to detect that the side surface on the rear side is pressed against guide rail.
