Component transfer device and method

摘要

A component transfer device according to the present invention includes a holding mechanism that positions and holds a component on a carrying surface located at a predetermined height and a pull-out unit that pulls out the component held on the carrying surface by the holding mechanism in a horizontal direction. The pull-out unit includes a grasping member that can separably grasp the component from a vertical direction, a cam member that causes the grasping member to perform a component grasping operation and a component releasing operation at predetermined timings by exercising a cam function to the grasping member, a driving mechanism that drives the cam member and the grasping member, and a restraint mechanism that restrains a relative movement of the cam member with respect to the movable holder upon grasping operation.

主权项

1. A component transfer device comprising:
a holding mechanism for positioning and holding a component on a carrying surface located at a predetermined height; and a pull-out unit for pulling out the component held by the holding mechanism in a horizontal direction, wherein the pull-out unit includes a grasping member configured to separably grasp the component from an opposite direction, a cam member for exercising a cam function with respect to the grasping member to effect a grasping operation of the component and a releasing operation of the component at predetermined timings, and a driving mechanism for driving the cam member and the grasping member, the holding mechanism includes an elevation unit for moving up and down a rack that accommodates the components on a plurality of stages, the grasping member includes a first arm member having a first contact portion capable of separably coming into contact with one side surface of the component, and a second arm member having a second contact portion capable of separably coming into contact with another side surface of the component, the cam member includes a guided portion that is guided reciprocatably in a pull-out direction of the component, a first cam portion that exercises the cam function with respect to the first arm member, and a second cam portion that exercises the cam function with respect to the second arm member, the driving mechanism includes a movable holder that reciprocates in the pull-out direction, the movable holder having a horizontal guide portion for guiding the guided portion in the pull-out direction and another guide portion for guiding a first follower portion of the first arm member and a second follower portion of the second arm member in the opposite direction, and a first urging member for generating an urging force so as to make the first follower portion engage with the first cam portion and make the second follower portion engage with the second cam portion, and further comprising a restraint mechanism for restraining a relative movement of the cam member with respect to the movable holder.
