Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention mainly relates to a blade for an impeller, which is press-molded by a press machine and discharged to a predetermined take-out position, in front of a setting jig and other attached objects. The present invention relates to a work setting device for setting one sheet per sheet.

(Prior Art) According to Japanese Patent Laid-Open No. 58-78909, a stocker for stacking and setting a large number of blades in the same posture as the mounting posture for a shell of an impeller and a vertically movable free-standing magnet with a permanent magnet attached There is known a blade setting device which is provided with a holding tool, receives the blade from the outlet at the tip of the stocker by the raising and lowering operation of the holding tool, and sets one blade to the lower setting jig.

(Problems to be solved by the invention) In the above-mentioned conventional one, it is necessary to manually set the blade in the stocker, and the setting work is troublesome. Therefore, the blade is press-molded by the press machine and the predetermined dispensing position is set. It is desired to develop a setting device that automatically sets the blades to be delivered to the front attached object.

By the way, the blade is ejected in a horizontal posture.In this case, the outer edge of the blade that comes into close contact with the shell is ejected toward the front in the transport direction, and the inner edge of the blade is grasped from the rear by a grasping tool and the front assembly If you set it on the accessory, you can insert the blade into the object to be assembled without changing its posture so much, but the gripping tool interferes with the dispensing device that dispenses the blade from the mold and grips the blade. I can't.

Eventually, the blade is ejected with its inner edge facing forward, and the inner edge of the blade is gripped from the front by a gripping tool so that the outer edge of the blade, that is, the rear edge in the transport direction, is directed forward and downward to the object to be assembled. There is no choice but to change the posture and insert it.

Therefore, it is conceivable to arrange an industrial robot having a grasping tool for detachably grasping the blade attached to the robot arm on the side of the dispensing device. However, in this case, the industrial robot is expensive and the installation space is large. There is also a widely needed problem.

An object of the present invention is to provide a compact and inexpensive set device that satisfies the above demands.

(Means for Solving the Problem) In order to achieve the above object, in the present invention, a work to be delivered to a predetermined take-out position in a substantially horizontal posture is transferred to a set jig or other attached object in the front in the work transfer direction. In a setting device that sets in such a posture that the trailing edge faces substantially downward,
A movable frame having a rear end to which a gripping tool for detachably gripping a work is attached, a crank arm pivotally supporting the movable frame, a first link having one end pivotally attached to the crank arm, and a first link other than the first link. A slider provided at the front of the crank arm, which is pivotally attached at its end and which moves substantially linearly with the rotation of the crank arm, and the first link is moved forward by the rotation of the crank arm to the slider. A fixed arm protruding from the slider in a positional relationship such that the angle formed by the first link is narrowed when rotated, and one end is pivotally attached to the fixed arm and the other end is pivoted to the front end of the movable frame. Second worn
A link, and an extension line of a connecting line connecting a pivotally attached portion of the second link to the fixed arm and a pivotally attached portion of the movable frame to a front end of the movable frame passes above a support shaft of the movable frame to the crank arm. I chose

(Operation) After holding the work delivered to the take-out position with the holding tool in a state where the movable frame is in a substantially horizontal posture, the crank arm is rotated forward.

According to this, the slider moves substantially linearly forward through the first link and the first link rotates with respect to the slider, and the angle between the fixed arm fixed to the slider and the first link is narrowed, As a result, the movable frame rotates with respect to the crank arm via the second link so that the rear end of the gripping tool faces downward.

Then, due to the movement of the movable frame downward by the circular motion of the crank arm and the rotation of the movable frame with respect to the crank arm, the work is inserted into the attached object from above with the trailing edge of the work facing downward. .
