Definitions
- the present invention relates to a workpiece transfer system using a robot.
- Patent Document 1 discloses a workpiece transfer system in which a chuck device is attached to a robot.
- the chuck device has a pair of claws in which a V-shaped depression is formed on a work contact surface for gripping a cylindrical work.
- some chuck devices have three claws with a flat workpiece contact surface.
- the center of gravity of the work body is not necessarily located at the center of the gripping portion. Therefore, when the workpiece is transported by the robot, the rotational force around the gripping portion acts on the workpiece due to the inertial force during acceleration or deceleration. For this reason, there is a possibility that the workpiece rotates (that is, the workpiece cannot be conveyed to a proper position) only by gripping the grip portion with the three claws.
- an object of the present invention is to provide a workpiece transfer system that can prevent rotation of a workpiece when a workpiece including a workpiece main body and a gripping portion is transferred by a robot.
- a workpiece conveyance system of the present invention includes a workpiece including a workpiece main body, a cylindrical gripping portion protruding from the workpiece main body, and an engagement plate attached to a front end surface of the gripping portion; A chuck device including three claws for gripping the grip portion from the radial direction of the grip portion; and a robot to which the chuck device is attached; and the engagement plate is disposed along the distal end surface of the grip portion.
- An engagement groove into which one of the three claws is fitted is formed in the extension part.
- the workpiece can be prevented from rotating by fitting one claw of the chuck device into the engagement groove of the engagement plate.
- the above effect can be obtained with a simple configuration in which the engagement plate is attached to the grip portion.
- the engaging plate has a shape in which the projecting portion projects only in the direction from the gripping portion toward one of the three claws, and fits within the outline of the gripping portion in a region corresponding to the remaining two claws. Also good. According to this configuration, the engagement plate can be minimized.
- the robot may include an articulated arm having a plurality of degrees of freedom.
- FIG. 2 is a cross-sectional plan view taken along line II-II in FIG. 1 immediately before the chuck device grips a workpiece gripping portion.
- FIG. 3 is a sectional side view taken along line III-III in FIG. 2.
- FIG. 2 is a cross-sectional plan view taken along line II-II in FIG. 1 immediately after the chuck device grips a workpiece gripping portion.
- FIG. 5 is a cross-sectional side view taken along line VV in FIG. 4. It is a cross-sectional top view of the workpiece conveyance system of a modification.
- FIG. 7 is a sectional side view taken along line VII-VII in FIG. 6.
- FIG. 1 shows a workpiece transfer system 1 according to an embodiment of the present invention.
- the workpiece transfer system 1 includes a workpiece 2 and a robot 4 that transfers the workpiece 2.
- the workpiece 2 includes a workpiece main body 21, a columnar gripping portion 22 protruding from the workpiece main body 21, and an engagement plate 23 attached to a distal end surface 22a (see FIG. 3) of the gripping portion 22.
- the work main body 21 has a plate shape, and the gripping portion 22 protrudes in the thickness direction of the work main body 21 in the vicinity of the edge of the work main body 21.
- the distal end surface 22 a of the gripping portion 22 is orthogonal to the central axis of the gripping portion 22, and the engagement plate 23 is parallel to the distal end surface 22 a of the gripping portion 22.
- the robot 4 includes an articulated arm 41 having a plurality of degrees of freedom.
- the chuck device 3 is attached to the articulated arm 41.
- the robot 4 is not limited to the one including the articulated arm 41, and may be a uniaxial robot such as a linear actuator, for example.
- the chuck device 3 supports the three claws 33 that grip the grip portion 22 from the radial direction of the grip portion 22, the three sliders 32 to which the claws 33 are fixed, and the slider 32.
- a chuck body 31 is included.
- the chuck body 31 is formed with three grooves extending in the radial direction from the center of the chuck body 31 at intervals of 120 degrees, and the slider 32 is fitted in these grooves.
- Each claw 33 has substantially the same shape as the slider 32. However, in the radial direction of the chuck body 31, the inner end portion of each claw 33 is tapered so that the width is narrower than the slider 32.
- One of the three claws 33 (the lower claw in FIG. 2) is also a rotation preventing claw.
- each claw 33 has a flat work contact surface 33 a that is orthogonal to the radial direction of the chuck body 31.
- the chuck device 3 grips the grip portion 22 in a state where the tip end surface 22a of the grip portion 22 is located at an intermediate position of the workpiece contact surface 33a.
- the claw 33 grips a portion of the grip portion 22 adjacent to the tip surface 22a.
- the engagement plate 23 described above includes an overhanging portion 24 that protrudes from the grip portion 22 along the distal end surface 22a of the grip portion 22, as shown in FIG.
- the engagement plate 23 projects only in the direction in which the projecting portion 24 is directed from the gripping portion 22 to one of the three claws 33 (the lower claw in FIG. 2), and corresponds to the remaining two claws 33.
- the region has a shape that fits within the outline of the gripping portion 22.
- the overhanging portion 24 is formed with an engagement groove 25 into which one of the three claws 33 (a claw for preventing rotation) is fitted.
- the width of the engaging groove 25 is substantially equal to the width of the inner end of the claw 33 for preventing rotation.
- the depth of the engagement groove 25 in the radial direction of the grip portion 22 is greater than the distance from the grip portion 22 to the tip of the overhang portion 24. For this reason, a part of the front end surface 22 a of the grip portion 22 is exposed upward through the engagement groove 25.
- the articulated arm 41 moves the chuck device 3 directly above the grip portion 22. Thereafter, the articulated arm 41 lowers the chuck device 3 and inserts the upper end portion of the grip portion 22 into the inside of the three claws 33. Accordingly, the positional relationship between the three claws 33 and the engagement plate 23 is as shown in FIGS.
- the chuck device 3 moves the three claws 33 together with the slider 32 radially inward. Accordingly, the positional relationship between the three claws 33 and the engagement plate 23 is as shown in FIGS. 4 and 5. That is, in FIG. 2, the lower claw 33 is fitted into the engagement groove 25 of the engagement plate 23. Therefore, the lower claw 33 in FIG. 2 also functions as a positioning claw. Further, since the three claws 33 move inward in the radial direction in synchronization, the center of the grip portion 22 automatically coincides with the center of the chuck body 31 by the movement of the three claws inward in the radial direction.
- the one claw 33 of the chuck device 3 fits into the engagement groove 25 of the engagement plate 23, thereby preventing the workpiece 2 from rotating.
- the above effect can be obtained with a simple configuration in which the engagement plate 23 is attached to the grip portion 22.
- the robot 4 includes the multi-joint arm 41 as in the present embodiment, the inertial force acts on the workpiece 2 not only when the conveyance is accelerated and decelerated, but also when the workpiece 2 is turning. Remarkably can be obtained.
- the tolerance between the width of the engagement groove 25 and the width of the claw 33 for preventing rotation is tightened (in other words, their width). Width can be matched with high accuracy). As a result, the rotation of the workpiece 2 can be extremely effectively prevented.
- each claw 33 has a workpiece contact surface 33 a that contacts the side surface of the grip portion 22 below the tip surface 22 a of the grip portion 22, and the workpiece contact surface 33 a.
- You may have the recessed part 33b above.
- the claw 33 may grip a portion of the grip portion 22 away from the tip surface 22a.
- the overhang portion 24 may overhang the entire circumference from the grip portion 22.
- the engagement plate 23 can be minimized if the overhanging portion 24 protrudes in only one direction from the gripping portion 22 as in the above embodiment.
