Workpiece feeding device

Abstract

With a simple configuration and structure, it supplies the workpiece to be picked up to the robot with high positional accuracy. [Solution] One aspect of the work supply device according to the present invention sequentially supplies parts to a robot that picks up parts at predetermined positions, and comprises a support body 20 that is rotatable about a vertical axis and has a plurality of support plates 25 around the axis, each of which is inclined downward or hangs vertically as it moves outward from the side of the axis; a part holding jig 27 provided on each of the plurality of support plates, which can hold the part detachably while restricting the position of the lower end of the part by the part's own weight; a rotation drive unit 33 that rotates the support body about the axis; a position restricting unit 35 that restricts the rotation of the support body when any support plate is oriented in a predetermined direction and releases the restriction when the support body is rotated; and a control unit that rotates the support body by the drive unit so that the workpieces to be picked up sequentially come to the predetermined positions, and then restricts the rotation of the support body by the position restricting unit.

Claims

1. A workpiece supply device that sequentially supplies workpieces to a robot that picks up workpieces at predetermined positions, a) A support body that is rotatable about a vertical axis and has a plurality of support surfaces around the axis that are inclined downward or hang vertically as they extend outward from the side of the axis, b) One or more workpiece holding parts provided on each of the plurality of support surfaces, which hold the workpiece detachably while restricting the position of the lower end of the workpiece by the weight of the workpiece, c) A drive unit that rotates the support around the axis, d) A position restricting unit that restricts the rotation of the support body when any of the plurality of support surfaces is oriented in a predetermined direction, and releases the restriction when the drive unit rotates the support body, e) A control unit that controls the operation of the drive unit and the position restricting unit, wherein the drive unit rotates the support so that the workpiece to be picked up is sequentially brought to the predetermined position, and then the position restricting unit restricts the rotation of the support, f) A movable frame on which the support is mounted, g) A fixed part that is separate from the frame part and is equipped with the drive unit, A workpiece supply device comprising the following: the drive unit is connected to the shaft of the support, and the support is made rotatable, with the frame portion positioned in a predetermined position relative to the fixed portion.

2. A workpiece supply device that sequentially supplies workpieces to a robot that picks up workpieces at predetermined positions, a) A support body that is rotatable about a vertical axis and has a support surface around the axis that is inclined downward or hangs vertically as it extends outward from the side of the axis, b) Multiple workpiece holding parts provided at different positions on the single support surface, which hold the workpiece detachably while restricting the position of the lower end of the workpiece by the weight of the workpiece, c) A drive unit that rotates the support around the axis, d) A position restricting unit that restricts the rotation of the support when any of the plurality of workpiece holding units is oriented in a predetermined direction, and releases the restriction when the drive unit rotates the support, e) A control unit that controls the operation of the drive unit and the position restricting unit, wherein the drive unit rotates the support so that the workpiece to be picked up is sequentially brought to the predetermined position, and then the position restricting unit restricts the rotation of the support, f) A movable frame on which the support is mounted, g) A fixed part that is separate from the frame part and is equipped with the drive unit, A workpiece supply device comprising the following: the drive unit is connected to the shaft of the support, and the support is made rotatable, with the frame portion positioned in a predetermined position relative to the fixed portion.

3. The workpiece supply device according to claim 1 or 2, wherein the fixed portion and the frame portion each include a connecting mechanism that fixes their positions together.

4. The workpiece supply device according to claim 1 or 2, wherein the angle of inclination of the support surface with respect to the horizontal plane is in the range of 5° to 90°.

5. The workpiece supply device according to claim 1, wherein the number of support surfaces is in the range of 2 to 16, and the support surfaces are arranged radially around the axis when viewed from above.

6. The workpiece feeding device according to claim 1 or 2, wherein the position regulating portion includes a pin that is movable forward and backward from the outside of the support toward the support, and an opening formed at a predetermined position on the support through which the pin can be inserted when the pin has advanced.

7. The workpiece supply device according to claim 1 or 2, wherein the support surface is composed of a plate-shaped member having a plurality of holes, and the workpiece holding portion is a positioning pin inserted into the holes, or a workpiece holding jig attached to the plate-shaped member using the holes.

8. The workpiece supply device according to claim 1 or 2, wherein the robot picks up the workpiece using a hand that utilizes gripping or suction.
