摘要:
A holding apparatus and a holding unit are disclosed. The holding apparatus (4) includes a base plate (21), a fixed holding member (22) fixed on the base plate, a first movable holding member (11) arranged in opposed relation to and having a face adapted to operate in collaboration with the fixed holding member for holding a workpiece, a second movable holding member (12) adapted to operate in collaboration with said face of said first movable holding member in operatively interlocked relationship therewith for holding a workpiece, and a drive device (19) for driving the first movable holding member and the second movable holding member in operatively interlocked relationship with each other. Therefore, holding power can be increased easily without a large space. The holding apparatus may further include a removing device (24,25,26) for removing the second movable holding member from between the first movable holding member and the fixed holding member when holding the workpiece (20) with the first movable holding member and the fixed holding member.

A transfer robot system with a manipulator (18). The transfer robot system includes a track (16) extending between a first position (12) at which a container (60) containing a workpiece (64) is placed and a second position (14) to which the workpiece in the container is fed; a manipulator (12) movable along the track and capable of holding the container and the workpiece; a temporary container-depository (20) movable along the track synchronously with the manipulator, the container taken out from the first position by the manipulator being temporarily put thereon; a workpiece detecting section (22) for detecting the position and the orientation of the workpiece, contained in the container put on the temporary container-depository, during a period when the manipulator and the temporary container-depository move along the track synchronously with each other; and a transfer control section (24) for controlling the manipulator, based on a detection result in the workpiece detecting section, to make the manipulator pick out the workpiece from the container put on the temporary container-depository and feed the workpiece picked from the container to the second position.

A robot hand (10) includes a drive unit (12) having a pair of moving elements (14,16) provided so as to be movable in a lateral direction with respect to a center axis (O) extending parallel with a longitudinal direction of an arm part to which the robot hand is attached, a pair of gripping claws (18,20) each coupled to one of the pair of moving elements of the drive unit, and a joint (22) for coupling the pair of gripping claws to each other so as to be pivotable. Each of the pair of gripping claws has a base end (18a,20a) coupled to one of the moving elements so as to be pivotable and a front end (18b,20b) for engaging with a workpiece (W). The pair of moving elements are operated to approach and move apart from each other in a lateral direction with respect to the center axis, thereby making the pair of gripping claws pivot about the joint and making the front ends of the gripping claws move apart from or approach each other.

A flexible workpiece assembling method for assembling a flexible workpiece (W) with an object (60) by using a first robot (20) comprising a first hand (21) and a second robot (30) comprising a second hand (31) includes the steps of: gripping a first portion of the flexible workpiece by the first hand and gripping a second portion of the flexible workpiece different from the first portion by the second hand; moving the flexible workpiece to the object through a cooperating operation of the first and second robots; deforming the flexible workpiece into a shape corresponding to the nonflexible object by the first and second robots; and assembling the flexible workpiece onto the nonflexible object by the first and second robots. As a result, the flexible workpiece can be accurately assembled onto the nonflexible object without breaking or tearing. The first and second robots may comprise a pushing means for pushing the flexible workpiece into the object.

A robot handling system (10) using a robot hand (30) to convey a workpiece (40), provided with a first wrist element (24) at a front end (12a) of an arm (12) of the robot, a second wrist element (25) perpendicular to this, a third wrist element (26) perpendicular to this, and a connecting means (60) connecting the third wrist element and a hand body (31) of the robot hand, the hand body being arranged so that an inertia moment of the hand body about a vertical axial line becomes larger than the inertia moments of the hand body about two mutually perpendicular horizontal axial lines, the connecting means (60) connects the third wrist element (26) and hand body (31) so that a third axial line of the third wrist element (J6) and the hand body are arranged in a horizontal plane, and a posture of the hand body is changed about the vertical axial line in the state with the third axial line of the third wrist element arranged in a horizontal plane. Due to this, the robot hand can be made to rotate over the limit of the allowable inertia moment.

A handling robot system, including a table (14) having a placement surface (12) for placing a plurality of articles (Wa,Wb); an article dispersing mechanism (16) for dispersing the articles (Wa,Wb) placed on the placement surface (12) of the table (14) across the placement surface (12); a vision sensor (18) for detecting each of the articles (Wa,Wb) dispersed on the placement surface (12) of the table (14); and a robot (20) operating, based on article detection data (Dw) from the vision sensor (18), to hold the articles (Wa,Wb) one by one.
摘要:
A handling robot system, including a table having a placement surface for placing a plurality of articles; an article dispersing mechanism for dispersing the articles placed on the placement surface of the table across the placement surface; a vision sensor for detecting each of the articles dispersed on the placement surface of the table; and a robot operating, based on article detection data from the vision sensor, to hold the articles one by one. The article dispersing mechanism includes a partition member capable of producing a relative motion in relation to the table, the partition member being disposed in proximity to the placement surface with a gap defined therebetween, to divide a space adjoining the placement surface into a first region to which the articles are brought and a second region at which the robot operates to hold the articles transferred from the first region; and a drive control section for causing the relative motion between the table and the partition member in accordance with a program describing a mode of the relative motion. A certain number of articles are dispersed, as a result of the relative motion produced under the control of the drive control section, to permit the articles to pass through the gap on the placement surface, and are transferred from the first region to the second region.
