Axial-type electronic component inserting method

A method of inserting, into a board, axial-type electronic components, wherein each of the electronic components has a main body and a pair of lead wires atending from the main body and belongs to an assembly of axial-type electronic components connected by a tape as arranged at regular intervals, wherein the axial-type electronic components are grasped with a plurality of chucks which are intermittently moved to a component supplying position and a component transferring position, respectively, each of the chucks comprising protruding grasping pieces having first grasping grooves and second grasping grooves, the first grasping grooves having inner surfaces for grasping end portions of each of a first kind of the axial-type electronic components whose taped portions are of a first tape interval, the second grasping grooves having inner surfas for grasping end portions of each of a second kind of the al-type electronic components whose taped portions are of a second tape interval smaller than the first tape interval, wherein a depth of each of the first grasping grooves is smaller than a depth of each of the second grasping grooves, the method including first and second component inserting cycles;

• wherein said first component inserting cycle comprises
• a first process of
• taking out an initial gge of the axial-type electronic components from a component supplying device which retains the assembly of axial-type electronic components connected by the tape while a first of the chucks grasps end portions of the assembly at the component supplying position, such that the inner surfaces of the second grasping grooves of the first chuck vented from contacting the lead wires of the initial axial-type electronic component when the lead wires of the initial axial-type electronic component are grasped by the inner surfaces of the first grasping grooves of the first chuck when the initial axial-type electronic component grasped by the first chuck is one of the first kind of the axial-type electronic components, and
• a component delivering process of
• moving to a component inserting device the first chuck which has already grasped the initial axial-type electronic component in said first process, and delvering the initial axial-type electronic component to the component inserting device from the first chuck;
• wherein said second component inserting cycle comprises
• a first process of
• taking out a subsequent of the axial-type electronic components from a component supplying device which retains the assembly of axial-type electronic components connected by the tape while a second of the chucks grasps end portions of the assembly at the component supplying position, while preventing the inner surfaces of the second grasping grooves of the second chuck from contacting the lead wires of the subsequent axial-type electronic component when the lead wires of the subsequent axial-type electronic component are grasped by the inner surfces of the first grasping grooves of the first chuck when the subsequent axial-type electronic component grasped by the second chuck is one of the first kind of the axial-type electronic components;
• and
• wherein said component delivering process of said first component inserting cycle is executed simultaneously with said first process of said second component inserting cycle.
