Such a six-axis articulated robot 71 can control the chuck 8 of the hand 97 in various postures by operating each joint.

  As shown in FIG. 5, the hand 97 has a frame body 98 formed in a lattice shape in plan view, and a plurality of chucks 8 that hold or release the workpiece w are attached to the frame body 98. In the present embodiment, nine chucks 8 of 3 × 3 in the vertical and horizontal directions are attached to the frame body 98, but the number is not limited to nine. The chuck 8 has a suction port 81 that sucks (sucks) air, sucks and holds the workpiece w by a vacuum force, and releases the workpiece w by stopping suction or conversely blowing air. Note that the chuck 8 is not limited to a vacuum type, and may include an electromagnet that attracts or releases the metal workpiece w by turning it on and off.

  As shown in FIGS. 1 to 3, the multi-joint robot 71 sucks and holds the workpieces w stacked on a reed (paretine) 72 on the chuck 8 by holding the joints 8 by appropriately operating each joint. As shown in FIG. 6, the workpiece w is brought close to the inclined surface 21 in accordance with the inclination angle θ of the inclined table 2, and then the workpiece w is released from the chuck 8. The multi-joint robot 71 is operated so as to convey 5 to 9 workpieces w from the net 72 to the tilt table 2 at intervals of 10 to 20 seconds, and even if the workpieces w are not attracted to all the chucks 8. I do not care. A vacuum sensor is connected to each chuck 8 so that it can be detected whether or not the workpiece w has been sucked, and five or more of the nine vacuum sensors have detected that the workpiece w has been sucked.

The 2nd supply conveyor Y which conveys the workpiece | work w discharged | emitted from 1 supply conveyor X is arrange | positioned. The workpiece w on the second supply conveyor Y is supplied to a machine tool (press machine) Z used in the next process. The conveyance speed of the second supply conveyor Y is set faster than the conveyance speed of the first supply conveyor X. This is because the interval between the workpieces w on the second supply conveyor Y matches the workpiece input specification (spec) of the press machine Z.

  The press machine Z according to the present embodiment has a specification of loading 26 workpieces w per minute. If the pitch of the workpieces w (interval between the centers of the workpieces w) on the second supply conveyor Y is 300 mm, 2 The conveyance speed of the supply conveyor Y is about 130 mm / sec. On the other hand, in the 1st supply conveyor X, if the pitch of the workpiece | work w shall be 160 mm, the conveyance speed of the 1st supply conveyor X will be about 69 mm / sec. In the present embodiment, the diameter of the workpiece w is 150 mm as described above.

  As shown in FIG. 1, the tilt table 2, the diagonal conveyor 3, the horizontal conveyor 4, the net cage 72, and the articulated robot 71 are surrounded by a safety fence EN. In FIG. 1, CON is a control panel, COM is an image processing computer, and in FIG. 3, HC is a hand control device.

(Action / Effect)
An alignment method using the alignment apparatus 1 for plate-like workpieces w according to the present embodiment will be described.

  1 is held on the chuck 8 of the hand 97 of the articulated robot 71. After the workpiece w held by the chuck 8 is appropriately moved by the respective joints of the articulated robot 71 to approach the inclined surface 21 of the inclined table 2 in accordance with the inclination angle θ as shown in FIG. , Released from the chuck 8. In the present embodiment, the workpiece w is released from the chuck 8 after being brought close to the inclined surface 21 by about 1 to 3 times its plate thickness. Since each workpiece w is released in the state of being close to the inclined surface 21 at the same angle, the impact when landing on the inclined surface 21 can be suppressed as much as possible to prevent the occurrence of scratches. It is possible to prevent the inclined surface 21 from rolling down in a standing posture.

  As shown in FIG. 2, the workpiece w released from the chuck 8 slides down the inclined surface 21 and is conveyed in an oblique posture by the oblique conveyor 3 with its lower end supported by the widthwise end of the horizontal conveyor 4. Is done. As shown in FIG. 1, the workpiece w conveyed in an oblique posture on the oblique conveyor 3 is regulated from one side (upper side) in the width direction of the oblique conveyor 3 by a regulating plate 51 constituting the width regulating unit 5. They are slid down from the diagonal conveyor 3 onto the horizontal conveyor 4 and arranged in a line. Thereby, the plate-shaped workpiece | work w can be aligned on the horizontal conveyor 4 in a line, avoiding the bridge | bridging conventionally produced by restrict | squeezing the workpiece | work w from the left-right both sides of the width direction of a conveyor.

  Here, since the width of the conveying surface of the horizontal conveyor 4 is set to be less than twice the size (diameter) of the workpiece w (about 1.2 times in the present embodiment), the workpiece w of the horizontal conveyor 4 is Two are not arranged in the width direction on the transport surface. Therefore, it is possible to avoid a bridge caused by two workpieces w arranged on the horizontal conveyor 4 in the width direction. Further, even if a plurality of plate-like workpieces w slipped down from the oblique conveyor 3 to the horizontal conveyor 4 overlap on the horizontal conveyor 4, those workpieces w are not shown in FIG. By being regulated in the height direction by the plate body 61 constituting 6, the sheet is sent one by one from the outlet of the horizontal conveyor 4.

  By the way, the workpiece w sliding down the inclined surface 21 does not become an oblique posture along the oblique conveyor 3 but bounces to the end portion in the width direction of the horizontal conveyor 4 or the workpiece w already existing on the oblique conveyor 3. Also, a situation where the vehicle is separated from the oblique conveyor 3 can be considered. Even in this case, since the bound work w is captured by the horizontal conveyor 4 arranged in parallel to the oblique conveyor 3 and is conveyed by the horizontal conveyor 4, no problem occurs. In addition, the situation where the bound work w falls from the horizontal conveyor 4 is prevented by the side wall 41 provided along the side part of the horizontal conveyor 4.

  As shown in FIGS. 1 and 2, the workpiece (disk) w conveyed in an oblique posture along the oblique conveyor 3 has a lower surface in the thickness direction in contact with the oblique conveyor 3 and a lower end in the vertical direction. It is conveyed in contact with the horizontal conveyor 4. When the conveyance speed of the horizontal conveyor 4 and the conveyance speed of the oblique conveyor 3 are equal, the workpiece w is conveyed without rotating (spinning), and the conveyance speed of the horizontal conveyor 4 is made higher than the conveyance speed of the oblique conveyor 3. When it is fast or slow, it is conveyed while rotating. When the workpiece w on the oblique conveyor 3 rotates, the upper workpiece w (see FIGS. 1 and 2) stacked in an oblique posture on the upper end (upper edge) of the workpiece w in the vertical direction is contact-rotated and driven. The workpiece w becomes easy to fall.

  When the conveyance speed of the horizontal conveyor 4 is made faster than the conveyance speed of the diagonal conveyor 3, the workpiece w on the diagonal conveyor 3 rotates counterclockwise in FIG. 1, so that the workpiece w comes into contact with the regulating plate 51 that forms the width regulating section 5. Then, the workpiece w rolls along the regulating plate 51 and is smoothly slid down onto the horizontal conveyor 4. On the contrary, if the conveyance speed of the diagonal conveyor 3 is made faster than the conveyance speed of the horizontal conveyor 4, the number of workpieces stored on the diagonal conveyor 3 can be reduced, and the workpieces w are stacked in an oblique posture on the diagonal conveyor 3. The situation can be suppressed.

  The preferred embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the above-described embodiments, and various modifications within the scope of the claims. Needless to say, examples and modifications also belong to the technical scope of the present invention.

  INDUSTRIAL APPLICABILITY The present invention can be used for an alignment method and an alignment apparatus that align plate-like workpieces in a line along the conveying direction of a conveyor.
