JP 2004-203555 A

  However, in the above-described parts aligning and supplying apparatus, a part such as a square nut in which projections (protrusions) are provided at the four corners at the welded part with the workpiece can be applied because the sorting bar passes between the projections. If it is a part like a hex nut, the projection is arranged in a ring shape, and the sorting bar interferes with it and cannot be slipped through, so it cannot be applied as it is.

  In view of the above circumstances, an object of the present invention is to provide a component aligning and supplying apparatus that can align even parts having different shapes in the vertical direction, such as a flanged hexagon nut.

The invention described in claim 1 is a component alignment supply device comprising a rotor that magnetically attracts components stored in a hopper chamber, and a gate that aligns the components magnetically attracted to the rotor and supplies them to a chute. And
The rotor includes a plurality of magnet housing chambers provided at predetermined intervals in the circumferential direction, and a spherical permanent magnet that is housed in each magnet housing chamber so as to be movable in the circumferential direction, and magnetically attracts the components,
The gate has
The parts adsorbed on the rotor are
Passable when the surface to be welded is in the correct posture when being welded to the workpiece,
And,
A shape substantially projecting the part,
A passage restricting member having a passage passage formed in is disposed.

  According to this, it is possible to align even parts having different shapes on the surface side to be welded to the workpiece and the opposite surface side, for example, parts such as flanged hex nuts. It becomes possible.

Further, the surface of the passage restricting member on the rear side in the rotation direction of the rotor is formed to be inclined with respect to the rotation axis of the rotor,
When the parts adsorbed by the rotor are welded to the workpiece, the parts in a posture where the surface to be welded is not correct are dropped into the hopper chamber.

  According to this, if the surface of the passage restricting member on the rear side in the rotation direction of the rotor is made to follow the rotation axis of the rotor, parts that cannot pass through the passage may stay. By tilting, the parts can be easily dropped into the hopper chamber, and the stagnation of the parts can be suppressed.

The orthogonal shaft gear head 41 is attached to the rear surface of the rear plate 22. By the orthogonal shaft gear head 41, the driving force of the motor 40 is transmitted by converting the rotational axis from the left-right direction to the front-rear direction.

  As shown in FIGS. 6 and 7 and the like, the output shaft 41a of the orthogonal shaft gear head 41 protrudes to the inner surface side of the rear plate 22, and a bush 42 is externally fixed to the output shaft 41a. The bush 42 is fixed to the central portion of the rotating plate 51 of the rotor 50. As shown in FIG. 5, the rotating plate 51 can rotate in the counterclockwise direction a.

  As shown in FIGS. 5 to 7, the rotor 50 includes a disk-shaped rotating plate 51 and an outer ring 52 whose outer shape is a truncated cone shape, and is formed in a dish shape whose rear side is open.

  An outer ring 52 extends toward the rear plate 22 at the outer peripheral end of the rotating plate 51. The outer surface of the outer ring 52 acts as a nut adsorption surface 52a for magnetically adsorbing the flanged hexagon nut 200 in the hopper chamber 35.

  The first magnet holder 53 includes a pair of side wall pieces 53a and 53a, a connecting piece 53b that connects the side wall pieces 53a and 53a, and an attachment piece 53c that is formed orthogonal to the connecting piece 53b. ing.

  The first magnet holder 53 has a pair of side wall pieces 53a, 53a and a connecting piece 53b, and is formed in a substantially U shape when viewed from the front-rear direction.

And a formed support piece 54b. The attachment piece 53c and the support piece 54b are overlapped and attached to the rear surface of the rotating plate 51 by bolting or the like.

  A region surrounded by the rotating plate 51, the outer ring 52, the first magnet holder 53, and the magnet holder cover 54 is a magnet housing chamber 56 that houses the spherical permanent magnet 55.

  The magnet housing chamber 56 is formed so that the spherical permanent magnet 55 can move in the circumferential direction of the rotating plate 51.

  In this embodiment, the magnet housing chamber 56 sandwiches the reference line S when the VII-VII line passing through the axis of the output shaft 41a as the rotation axis of the rotor 50 in FIG. Six are arranged so as to be line symmetric.

  A second magnet holder 57 and a tap plate 58 are disposed in the rotor 50.

  The second magnet holder 57 includes a rectangular flat holder piece 57a and an attachment piece 57c formed in a substantially L shape.

  The holder piece 57a has a through-hole 57b having a smaller radius than the spherical permanent magnet 55, and the spherical permanent magnet 55 is disposed in the through-hole 57b, and the spherical permanent magnet 55 is held by the rotating plate 51 and the holder piece 57a. It is possible.

  The second magnet holder 57 is attached to the rotary plate 51 by bolting or the like via the tap plate 58 in the attachment piece 57c.

  The distance between the rear end surface of the outer ring 52 and the rear plate 22 is narrow, so that the hexagon nut 200 with a collar does not go around the rear side of the rotary plate 51. As shown in FIGS. 5 and 6, the nut adsorption surface 52 a of the outer ring 52 forms an inclined surface that decreases in diameter from the rear plate 22 side toward the rotary plate 51 side, and has rotated to the upper end position. A downward slope is formed toward the rotating plate 51 side, in other words, toward the front plate 21 side. The downhill makes it easy for the flanged hexagon nut 200 that is attracted to the nut attracting surface 52a of the outer ring 52 and conveyed to the upper end position to slide down toward the front plate 21.

  The chute 70 is fixed to the left side plate 23 as shown in FIGS. A feeding hose (not shown) is connected to the left end portion of the chute 70.

  As shown in FIGS. 8 to 10, the sorting plate 61 constituting the gate 60 is rotated on the rear side in the radial direction of the rotating plate 51 of the chute 70 and above the outer ring 52 of the rotor 50. It is attached to the rear plate 22 via the attachment plate 65 along the direction.

  In the present embodiment, the sorting plate 61 has a mounting piece 61a and a sorting piece 61b and is formed in a substantially L shape. The mounting plate 61a is bolted to the mounting plate 65 and attached thereto. The mounting plate 65 is attached to the rear plate 22 by bolting. The sorting piece 61b is formed so as to be substantially parallel to the nut suction surface 52a of the outer ring 52 in the attached state.

  As shown in FIGS. 8 to 10, the distance from the lower end of the sorting piece 61 b of the sorting plate 61 to the nut suction surface 52 a of the outer ring 52 in the radial direction of the rotating plate 51 is the thickness of one flanged hexagon nut 200. And a distance smaller than the distance corresponding to the thickness of two flanged hexagon nuts 200.

  When the two or more collared hexagon nuts 200 are conveyed while being overlapped on the nut adsorption surface 52a of the outer ring 52, the sorting plate 61 is configured to receive only the collared hexagon nut 200 that is directly adsorbed on the nut adsorption surface 52a. The other hexagon nut 200 with a flange that is overlaid on the flanged hexagon nut 200 is dropped.

  On the rear side of the chute 70 in the rotation direction of the rotor 50, as shown in FIGS.

  The passage forming member 67 has a front wall 67a and an upper wall 67b, is formed in a substantially L-shaped cross section, and is formed in an arc shape corresponding to the shape of the outer ring 52 when viewed from the front-rear direction. The inner surface side of the passage forming member 67 is disposed so as to face the nut adsorption surface 52a and the rear plate 22 of the outer ring 52, and is surrounded by the passage formation member 67 and the nut adsorption surface 52a and the rear plate 22 of the outer ring 52. However, it is a passage through which the flanged hexagon nut 200 passes.

  A passage restricting member 62 is disposed in the opening portion of the passage forming member 67 on the rear side in the rotation direction of the rotor 50.

  The passage restriction member 62 is formed of a nonmagnetic metal in a rectangular flat plate shape, and has a passage passage 62a formed by cutting out from the lower end surface toward the upper end surface. In the present embodiment, the passage passage 62a is formed by cutting out a convex hex nut 200 that is substantially projected.

  The passage restricting member 62 can pass through the passage passage 62a when the flanged hexagon nut 200 is in the correct suction posture in which the collar portion 202 is positioned on the nut suction surface 52a side (lower side), and is opposite to the nut suction surface 52a. In the case of an incorrect suction posture in which the collar portion 202 is positioned (upper), the passage passage 62a cannot be passed.

  The passage restricting member 62 is attached to the attachment bracket 66, and the attachment bracket 66 is attached to the upper wall 67 b of the passage forming member 67.

  As shown in FIG. 9, the surface 62b of the passage restricting member 62 on the rear side in the rotation direction of the rotor 50 is disposed so as to be inclined with respect to the rotation axis 50a of the rotor 50.

  In the present embodiment, the surface 62b on the rear side in the rotational direction is disposed so as to be inclined to the left by 30 degrees (60 degrees with respect to the rear plate 22) with respect to the rotational axis 50a of the rotor 50 when viewed from the vertical direction. The flanged hexagonal nut 200 adsorbed on the nut adsorbing surface 52a of the flange is allowed to drop into the hopper chamber 35 parts whose posture to be welded (back surface 200a) is incorrect when being welded to the workpiece. .

  As shown in FIGS. 8 and 9, a guide member 63 is disposed on the rear plate 22 side of the passage restricting member 62 and on the rear side in the rotational direction of the rotor 50. The guide member 63 guides the collared hexagon nut 200 from the rear plate 22 side of the outer ring 52 to the front plate 21 side.

  The sorting plate 61, the passage restricting member 62, and the passage forming member 67 constitute a gate 60, and the box 20, the rotor 50, and the gate 60 are made of a nonmagnetic material.

  Next, the operation of the component alignment supply device 10 will be described.

  When a predetermined amount of collared hexagon nut 200 is put into the hopper chamber 35 and the parts alignment supply device 10 is started, the motor 40 rotates and the rotor 50 rotates counterclockwise a via the orthogonal shaft gear head 41. . When the rotor 50 is rotated, the six spherical permanent magnets 55 are usually attached to the flanges in the hopper chamber 35 when entering the region of the hopper chamber 35 from the region of the hopper front chamber 36 as viewed from the front-rear direction. The hexagon nut 200 is magnetically attracted.

  The number of flanged hexagon nuts 200 and the posture of the flanged hexagon nuts 200 that are attracted to the nut attracting surface 52a of the outer ring 52 vary depending on the strength of the magnetic force of the spherical permanent magnet 55. When the collared hexagon nuts 200 overlap and are attracted to the outer ring 52, when the collared hexagon nuts 200 are conveyed to the position of the sorting plate 61, they are directly attracted to the outer ring 52. The flanged hexagonal nuts 200 other than the flanged hexagonal nut 200 come into contact with the sorting plate 61 and fall.

  Of the hexagon nuts 200 with flanges that have passed under the sorting plate 61, those having the correct posture in which the flange portion 202 is positioned on the nut suction surface 52a side pass through the passage passage 62a, and the incorrect flange portion 202 is positioned on the upper side. Those with a posture cannot pass through the passage 62a.

  The surface 62b on the rear side in the rotational direction of the passage restricting member 62 is inclined forward in the rotational direction with respect to the rotational axis 50a of the rotor 50, so that the flanged hexagon nut 200 that cannot pass through the passage passage 62a is on the front side in the rotational direction. And the nut suction surface 52a formed in an inclined manner slides down and falls.

  Further, the flanged hexagon nut 200 attracted to the rotating plate 51 by the spherical permanent magnet 55 held by the second magnet holder 57 rotates around the bush 42 fitted to the output shaft 41a, and the collared hexagon nut 200 To prevent the rotation of the rotor 50 from being hindered.

  The flanged hexagon nut 200 that has passed through the passage passage 62 a is guided into the chute 70 through the passage forming member 67. The flanged hexagon nut 200 guided into the chute 70 is supplied from the chute 70 to a supply head (not shown) via a supply hose (not shown).

  In this way, the component alignment supply device 10 supplies only the hexagon nut 200 with a flange whose rear surface 200a is adsorbed to the nut adsorption surface 52a of the outer ring 52 to the supply head. Then, the hexagon nuts 200 with flanges that are attracted to the nut attracting surface 52a of the outer ring 52 and are in an overlapping and incorrect posture are sorted by the sorting plate 61 and the passage regulating member 62 and dropped.

  In the component aligning and supplying apparatus 10 of the above embodiment, the rotor 50 that magnetically attracts the collared hexagon nut 200 as a component stored in the hopper chamber 35 and the collared hexagon nut 200 that is magnetically attracted to the rotor 50 are aligned. The rotor 50 includes a plurality of magnet housing chambers 56 provided at predetermined intervals in the circumferential direction, and a circle in each magnet housing chamber 56. A spherical permanent magnet 55 that is accommodated so as to be movable in the circumferential direction and magnetically attracts the flanged hexagon nut 200 is provided. When the flanged hexagonal nut 200 attracted to the rotor 50 is welded to the gate 60, A passage passage 62a formed so as to be able to pass when the surface (back surface 200a) to be welded is in a correct posture and having a shape substantially projected from the flanged hexagon nut 200. Passing regulating member 62 is disposed that.

  According to this, a part having a different shape on the surface (back surface 200a) side to be welded to the workpiece and the opposite side, a part having a different shape in the vertical direction, such as a hexagon nut 200 with a flange. Even so, they can be aligned.

  Further, the surface 62b on the rear side in the rotation direction of the rotor 50 of the passage restricting member 62 is formed to be inclined with respect to the rotation axis 50a of the rotor 50, and the hexagon nut 200 with a collar adsorbed to the rotor 50 is welded to the work The flanged hexagon nut 200 having a posture in which the surface to be welded (back surface 200a) is not correct is dropped into the hopper chamber 35.

  According to this, if the surface 62b on the rear side in the rotation direction of the rotor 50 of the passage regulating member 62 is set along the rotation axis 50a of the rotor 50, the flanged hexagon nut 200 that cannot pass through the passage passage 62a is retained. Therefore, by tilting the rotor 50 with respect to the rotation axis 50a, the flanged hexagon nut 200 can be easily dropped into the hopper chamber 35, and retention of the collared hexagon nut 200 can be suppressed.

  The component alignment supply device of the present invention is not limited to the above configuration. That is, various design changes can be made without departing from the gist of the present invention.

  For example, although the case where seven spherical permanent magnets 55 are used has been described in the above embodiment, the number and arrangement position thereof can be changed as appropriate.

  The present invention can also be applied to parts other than the flanged hexagon nut 200. In this case, the passage passage 62a of the passage restriction member 62 is formed in a shape substantially projecting the part to be applied.
