Description

Conveying path switching device, conveying system, and conveying path switching method Technical Field The present invention relates to a technique for switching a conveying path of a table conveyor between two fixed linear conveyors disposed on both sides of a movable linear conveyor by the movable linear conveyor. Background Patent document 1 describes a circulating conveyor apparatus that conveys a table conveyor in a circulating manner using a movable linear conveyor that conveys the table conveyor between two fixed linear conveyors arranged in parallel. In the endless conveying device, the movable linear conveyor is movable between a position opposed to one of the two fixed linear conveyors and a position opposed to the other. The mobile linear conveyor interfaces the table conveyor between one stationary linear conveyor and the table conveyor between the other stationary linear conveyor and the table conveyor at a position opposite the one stationary linear conveyor. Prior art literature Patent literature Patent document 1 WO2021/229781 Disclosure of Invention Problems to be solved by the invention In the endless conveying device as described above, two fixed linear conveyors each of which moves the conveying table between the movable linear conveyor and the movable linear conveyor are disposed on one side of the movable linear conveyor. Therefore, the movable linear conveyor may be a table conveyor that can be transferred between the movable linear conveyor and a fixed linear conveyor disposed on one side of the movable linear conveyor. In contrast, in a device in which two fixed linear conveyors are disposed on both sides of a movable linear conveyor, the movable linear conveyor needs to perform both transfer of a table conveyor between the movable linear conveyor and the fixed linear conveyor on one side and transfer of a table conveyor between the movable linear conveyor and the fixed linear conveyor on the other side. Thus, there are a scene in which the table conveyor is located at one end of the movable linear conveyor and is biased to one side with respect to the load of the movable linear conveyor, and a scene in which the table conveyor is located at the other end of the movable linear conveyor and is biased to the other side with respect to the load of the movable linear conveyor. Therefore, there is a problem that the end of one side of the movable linear conveyor sinks when the table conveyor is transferred to the fixed linear conveyor on the one side, or the end of the other side of the movable linear conveyor sinks when the table conveyor is transferred to the fixed linear conveyor on the other side, and thus transfer of the table conveyor to the fixed linear conveyor cannot be properly performed. In view of the above-described problems, an object of the present invention is to appropriately carry out transfer of a conveyor table between each fixed linear conveyor and a movable linear conveyor disposed on both sides of the movable linear conveyor, while supporting the movable linear conveyor against a bias against a load of the movable linear conveyor. Means for solving the problems The conveying path switching device includes a movable linear conveyor that conveys a conveying table in a predetermined conveying direction, a first support mechanism that supports a first end portion that is an end portion of one side of the movable linear conveyor in the conveying direction, and a second support mechanism that supports a second end portion that is an end portion of the other side of the movable linear conveyor opposite to the one side in the conveying direction, the first support mechanism and the second support mechanism supporting the movable linear conveyor, the movable linear conveyor moving in a switching direction within a movable range including a first position and a second position different from each other in a switching direction inclined with respect to the conveying direction, the first fixed linear conveyor being opposed to the first position from one side of the conveying direction, the second fixed linear conveyor being opposed to the second position from the other side of the conveying direction, the movable linear conveyor stopping at the first position and transferring the conveying table between the first fixed linear conveyor and the second fixed linear conveyor, the first support mechanism having a movable linear conveyor mounted on the first end portion and a second linear conveyor mounted on the movable guide member, and the movable linear conveyor having a second movable linear conveyor mounted on the first end portion and the second linear conveyor in the switching direction. The conveying system comprises a first fixed linear conveyor for driving a conveying table in a conveying direction, a second fixed linear conveyor for driving the conveying table in the conveying direction, and the conveying path switching device arranged between the first fixed linear conv
