Problems solved by technology
In view of this, it is structurally difficult for parallel link robots to perform tasks in narrow areas
This causes a problem in that if the area (placement portion) for placing the workpiece (target object) held by the suction pad (holding portion) is narrow (if the workpiece is to be put into a small container such as a box), Then it is difficult for the parallel link robot to perform the placement operation

Embodiment Construction
[0015] An embodiment of the present invention will now be described with reference to the accompanying drawings.
[0016] see first figure 1 , the configuration of the picking system 100 using the parallel link robot 10 according to one embodiment of the present invention will be described. The picking system 100 is an example of the "parallel link robot system" of the present invention.
[0017] Such as figure 1 As shown, the picking system 100 includes: the parallel link robot 10 fixedly installed on the lower surface (the surface on the arrow Z1 direction side) of the ceiling portion 50 ; the robot controller 20 configured to control the operation of the parallel link robot 10 ; and Two conveyors (first conveyor 30 and second conveyor 40 ) arranged below the parallel link robot 10 . The robot controller 20 is an example of the "control unit" of the present invention. The first conveyor 30 and the second conveyor 40 are examples of the "pickup section" and the "placement...

A parallel link robot system includes a picking section from which a target object is picked, a placing section on which the target object picked from the picking section is placed, the placing section being arranged in a height position lower than the picking section, a parallel link robot including a plurality of parallel-connected link mechanism units and a holding unit attached to tip end portions of the link mechanism units, and a control unit for controlling an operation of the parallel link robot. The control unit is configured to execute a control for causing the parallel link robot to perform a picking operation by which the target object is held and picked from the picking section and a placing operation by which the target object picked by the picking operation is placed on the placing section.
Description
technical field [0001] The present invention relates to a parallel link robot system, and more particularly, to a parallel link robot system provided with a parallel link robot including a plurality of parallel-connected link mechanism units. Background technique [0002] Conventionally, there is known a parallel link robot system provided with a parallel link robot including a plurality of link mechanism units connected in parallel (see, for example, Japanese Patent Application Publication No. 2011-88262). [0003] JP2011-88262A discloses a parallel link robot provided with three link units (link mechanism units) connected in parallel. In this parallel link robot, three link units are connected to each other at their tip portions. An end effector such as an adsorption pad (holding portion) for attracting and holding a workpiece (target object) is attached to the end portion of the link unit. The link unit is arranged to extend obliquely upward and outward from the tip por...
