Description

  The present invention relates to a parts feeder that discharges parts in a specific posture.

  A parts feeder is used as a device for discharging parts in a specific posture. The parts feeder imparts vibrations to the parts and transfers them in a certain direction. A parts feeder with this structure is very difficult to design to transfer parts efficiently. This is because the vibration of the hopper for transferring the parts may be partially different, or may not be vibrated so as to efficiently transfer the parts in all parts. For this reason, in consideration of the type and size of parts, the hopper that vibrates is designed exclusively, and the vibration mechanism of each hopper is finely adjusted and manufactured. For this reason, when parts having different weights and sizes are put into the hopper and transferred, some parts cannot always be smoothly transferred.

  Furthermore, the biggest drawback of parts feeders that transfer parts by vibration is that they are damaged by vibrated impacts. For example, when a bearing with a flange is transferred by a vibration type part feeder, the surface of the ball and the rolling surface may be damaged by the shock of vibration. Damaged bearings generate noise in use and become defective. For this reason, when the completed bearing is transferred by the parts feeder, it may become a defective product in the final transfer process.

  Furthermore, vibration-type parts feeders cannot eliminate noise caused by vibration. Moreover, it is difficult to transfer the parts quickly due to the restriction of the parts transfer speed. If the vibration is increased to increase the transfer speed, the noise is further increased. Nevertheless, parts cannot always be transferred quickly. Also, the stronger the vibration, the more severely damage the parts.

This drawback can be solved by a parts feeder that transports parts without vibrating them. (See Patent Document 1)

  As shown in FIG. 1, the parts feeder is arranged in an inner disk 1 arranged so as to be able to rotate in a horizontal or substantially horizontal plane, and in an attitude inclined to the inner disk 1 on the outer side of the inner disk 1. An outer ring plate 2 provided, a drive mechanism 3 for rotating the outer ring plate 2 and the inner disk 1, and an abnormal posture part transferred in an abnormal posture by the outer ring plate 2 from the outer ring plate 2 to the inner disk And a posture selection mechanism 4 for dropping it to 1. The outer ring plate 2 is disposed on the same plane as the inner disk 1, and is provided at a position higher than the inner disk 1, with a supply unit 5 to which a directional part P is supplied from the inner disk 1. And a rising and falling part 6. The outer ring plate 2 transfers the parts P supplied from the inner disk 1 from the supply unit 5 to the ascending and dropping unit 6. The posture selection mechanism 4 detects the direction of the part P, drops the abnormal posture part in the abnormal posture in the ascending / falling portion 6 from the outer ring plate 2 to the inner disk 1, and normal posture parts in the normal posture. Only the outer ring plate 2 that rotates by sorting out the particles is discharged to the outside.

  The parts feeder of this structure drops the abnormally-oriented parts on the inner disk at the rising and falling part. The parts dropped on the inner disk are discharged to the outside when they are transferred to the normal ring part by the outer ring plate. Fall down. For this reason, the parts are repeatedly dropped from the outer ring plate to the inner disk until they become normal posture parts, and are discharged to the outside when they become normal posture parts. Since the posture selection mechanism drops the abnormal posture parts, the dropped parts are sent again from the supply unit to the outer ring plate. With this mechanism, the parts feeder that discharges parts in a specific posture can discharge the parts in a specific direction while simplifying the entire mechanism.

  The parts feeder shown in FIG. 1 can discharge directional parts such as brazed bearings in the same direction. The barbed bearing is transferred in two directions shown in (1) and (2) of FIG. Accordingly, either one can be discharged as a normal posture part and the other can be dropped from the outer ring plate as an abnormal posture part, and only a part in a specific posture can be discharged. However, as shown in FIGS. 3 and 4, the parts transferred in the vertical postures (1) and (2) and the horizontal postures (3) and (4) are stable and accurate with the posture selection mechanism. However, it is difficult to select only a specific posture.

  The present invention was developed with the aim of further solving this drawback, and an important object of the present invention is to provide a parts feeder that can reliably sort parts to be transferred in various postures in a normal posture. It is to provide.

Further, as shown in FIG. 5, the parts feeder shown in FIG. 1 is a long and slender part, like a tapered roller of a taper bearing, and is transported in a horizontal posture, and parts having different shapes at both ends are reliably secured by a posture selection mechanism. However, there was a defect that could not be sorted stably.
A second object of the present invention is to provide a parts feeder that can reliably sort the posture of a part to be transported in a horizontal posture by a posture sorting mechanism and can discharge it with the same posture.

The parts feeder of the present invention has the following configuration in order to achieve the above-described object. The parts feeder discharges a directional part that is transported in a vertical position and a horizontal position, or a long and slender part that is transported in a horizontal position in a specific position.

A drive mechanism 3 that rotates and a posture selection mechanism 4 that passes normal posture parts transferred by the outer ring plate 2 and drops the abnormal posture parts from the outer ring plate 2 to the inner disk 1 are provided. The outer ring plate 2 that is inclined with respect to the inner disk 1 includes a supply unit 5 that is positioned at a lower part where the parts P are supplied from the inner disk 1, and a rising and falling unit 6 that is disposed at a higher position than the inner disk 1. With. The posture selection mechanism 4 includes a selection guide 22 provided in the ascending / falling portion 6 of the outer ring plate 2. The sorting guide 22 has a sorting unit 22 a that sorts by contacting the parts P transferred by the outer ring plate 2. The sorting unit 22a does not drop the part P whose center of gravity is located above the outer ring plate 2 from the outer ring plate 2, and uses the sorting guide 22 to remove the part P whose center of gravity is shifted to the inside of the outer ring plate 2. The normal posture parts are allowed to pass through without being dropped from the outer ring plate 2, but the abnormal posture parts are dropped from the outer ring plate 2. The rotated outer ring plate 2 transfers the parts P supplied from the inner disk 1 from the supply unit 5 to the ascending / falling unit 6, and the posture selection mechanism 4 moves the abnormal posture parts from the outer ring plate 2 to the inner disk. 1 is dropped, and only normal posture parts in a normal posture are selected and discharged to the outside by the outer ring plate 2.

  Further, in the parts feeder according to claim 1 of the present invention, a lateral posture groove 24 for guiding the part P in a posture in which the central axis is in the horizontal direction is provided on the upper surface of the outer ring plate 2 in the circumferential direction. This lateral posture groove 24 has a width smaller than the thickness of the part P, the part P is guided to the lateral posture groove 24 and transferred in a lateral posture, and the part is not guided to the lateral posture groove 24. The parts P are transferred in a vertical posture. This parts feeder sorts the parts transferred in the horizontal posture and the vertical posture by the sorting guide 22 of the posture sorting mechanism 4 and discharges only the normal posture parts.

  Further, the parts feeder according to claim 2 of the present invention has a lateral posture groove 24 that guides the part P in a posture in which the central axis is in the horizontal direction on the upper surface of the outer ring plate 2 and is directed from the center toward the outside. Are provided at predetermined intervals in the circumferential direction. This parts feeder guides the parts P to the lateral attitude grooves 24 and transports them in a lateral attitude, sorts the parts P transported in the lateral attitude by the sorting guide 22 of the attitude sorting mechanism 4, and discharges only the normal attitude parts. To do.

  Furthermore, the parts feeder according to claim 3 of the present invention is the parts feeder according to claim 2, wherein the parts feeder is located on the upper surface of the outer ring plate 2, in a plane including the outer ring plate 2, and in the radial direction, or The lateral posture grooves 24 are provided at a predetermined pitch in a posture that is in a plane including the outer ring plate 2 and is inclined with respect to the radial direction.

  The parts feeder of the present invention can arrange the supply part 5 of the outer ring plate 2 in the same plane as the inner disk 1.

  The parts feeder of the present invention can tilt both the inner disk 1 and the outer ring plate 2 with respect to the horizontal plane. In this parts feeder, the outer ring plate 2 is inclined upwardly from the supply unit 5 toward the ascending and dropping unit 6, and the inner disk 1 is descended from the supplying unit 5 toward the ascending and dropping unit 6 of the outer ring plate 2. Slope to the gradient.

  In the parts feeder of the present invention, the inner disk 1 can be disposed in a horizontal plane, and the outer ring plate 2 can be inclined upwardly from the supply unit 5 toward the ascending / falling unit 6. Furthermore, the parts feeder of the present invention can arrange the outer ring plate 2 horizontally, and can incline the inner disk 1 downwardly from the supply unit 5 toward the ascending and dropping unit 6 of the outer ring plate 2.

  In the parts feeder of the present invention, the drive mechanism 3 can rotate the inner disk 1 and the outer ring plate 2 in the same direction at the same number of rotations. Furthermore, the parts feeder of this invention can make the directional part P into parts from which the shape of both ends differs.

  The parts feeder of the present invention has a feature that parts that are transferred in a vertical posture or a horizontal posture can be reliably sorted to a normal posture. In the parts feeder of the present invention, a lateral posture groove is provided on the upper surface of the outer ring plate for transferring the parts. This is because the parts are transported in the vertical posture in the state where they are not guided, the parts transported in the horizontal posture and the vertical posture are sorted by the sorting guide of the posture sorting mechanism, and only the normal posture parts are discharged. The parts feeder of the present invention not only sorts the parts transferred in the vertical posture with the sorting guide as in the conventional case, but also guides the parts transferred in the horizontal posture to the lateral groove while accurately transferring them. Therefore, the parts transferred in various postures can be reliably sorted in the normal posture.

  Embodiments of the present invention will be described below with reference to the drawings. However, the embodiment shown below exemplifies a parts feeder for embodying the technical idea of the present invention, and the present invention does not specify the parts feeder as described below.

  Further, in this specification, in order to facilitate understanding of the scope of claims, the numbers corresponding to the members shown in the embodiments are referred to as “claims” and “means for solving the problems”. It is added to the member shown by. However, the members shown in the claims are not limited to the members in the embodiments.

  The parts feeder shown in FIGS. 6 and 7 are parts that are transferred in a horizontal horizontal position and a vertical vertical position on the outer ring plate as shown in FIGS. Alternatively, as shown in FIG. 5, parts or the like that are transferred in a horizontal posture and have different shapes at both ends are discharged in a specific posture. The part P has, for example, a cylindrical shape, a columnar shape, a rectangular tube shape, a prismatic shape, or a shape obtained by connecting these, and the shapes at both ends are different.

  The parts feeder shown in the figure includes an inner disk 1 disposed so as to be rotatable in a horizontal or substantially horizontal plane, an outer ring plate 2 disposed on the outer side of the inner disk 1, and the outer ring plate 2. And a drive mechanism 3 for rotating the inner disk 1 and a posture selection mechanism 4 for dropping an abnormal posture part transferred in an abnormal posture by the outer ring plate 2 from the outer ring plate 2 to the inner disk 1.

  The outer ring plate 2 is disposed in a posture inclined with respect to the inner disk 1. Further, a part of the outer ring plate 2 is arranged on the same plane as the inner disk 1 so that a directional part P can be supplied from the inner disk 1. The outer ring plate 2 includes a supply unit 5 to which the parts P are supplied from the inner disk 1 and a rising and falling unit 6 disposed at a higher position than the inner disk 1, and is supplied from the inner disk 1. The parts P are transferred from the supply unit 5 to the ascending / falling unit 6. The outer ring plate 2 is disposed to be inclined relative to the inner disk 1. To achieve this, as shown in FIG. 7, both the inner disk 1 and the outer ring plate 2 are tilted in the opposite direction, or the inner disk is leveled and only the outer ring plate is tilted, or Tilt the inner disc with the outer ring horizontal.

  As shown in FIG. 7, the parts feeder for inclining both the inner disk 1 and the outer ring plate 2 inclines the outer ring plate 2 from the supply part 5 of the part P toward the ascending and dropping part 6 in an upward gradient. The inner disk 1 is inclined downwardly from the supply part 5 toward the rising and falling part 6 of the outer ring plate 2. This parts feeder can reduce the inclination angle between the inner disk 1 and the outer ring plate 2 and increase the drop between the outer ring plate 2 and the inner disk 1 in the ascending / falling portion 6. The parts feeder in which the inner disk is disposed in a horizontal plane inclines the outer ring plate in an upward gradient from the supply unit toward the rising and falling unit. Also, the parts feeder that horizontally arranges the outer ring plate tilts the inner disk from the supply part toward the rising and falling part of the outer ring plate, and the rising and falling part is connected to the outer ring plate and the inner disk. Make a head.

  The inner disk 1 and the outer ring plate 2 can be manufactured by cutting a single metal plate into a circle with a laser or a press. This is because the outer peripheral edge of the inner disk 1 approaches the inner peripheral edge of the outer ring plate 2. However, it goes without saying that the inner disk 1 and the outer ring plate 2 can be made of different metal plates. The inner disk 1 has an outer diameter of, for example, 10 to 80 cm so that a large number of supplied parts P can be stored. When the inner disk 1 is enlarged, a large number of large parts can be stored. The outer ring plate 2 is designed to have a sufficient width as compared with the outer shape of the part P so that the part P can be placed and transferred thereon.

  The inner disk 1 and the outer ring plate 2 that are inclined with respect to each other are partly arranged on the same surface to serve as a supply unit 5 that supplies the parts P from the inner disk 1 to the outer ring plate 2. Since the supply part of an outer ring plate is a part which supplies parts from an inner side disk, it can also be arrange | positioned in a position lower than an inner side disk. As the inner disk 1 and the outer ring plate 2 are separated from the supply unit 5, the difference between the upper and lower sides becomes larger, and the portion where the vertical difference is the largest or the vicinity thereof is the rising and falling part 6. A gap is formed between the inner peripheral edge of the outer ring plate 2 and the outer peripheral edge of the inner disk 1. This is because the outer ring plate 2 is inclined with respect to the inner disk 1. In the parts feeder shown in FIGS. 6 and 7, the connecting wall 11 is fixed to the lower surface of the outer ring plate 2 so that the part P does not leak from this gap. The connecting wall 11 is connected to a disk 12 that rotates the outer ring plate 2.

  The outer ring plate 2 of FIGS. 8 and 9 is provided with a lateral posture groove 24 extending in the circumferential direction on the upper surface thereof for guiding the part P in a posture with the central axis as the horizontal direction. The width of the lateral posture groove 24 is smaller than the thickness of the part P. As shown in FIGS. 8 and 9, the parts are guided to the lateral posture groove 24 and transferred in the lateral posture. As shown, in a state where the part P is not guided to the horizontal posture groove 24, the part P is transferred in a vertical posture. The thickness of the part P is the outer diameter in the case of a cylindrical or columnar part, and the length of a diagonal line in the case of a rectangular tube or prismatic part. The lateral posture groove 24 in the figure is a U-groove having a cross-sectional shape with a curvature radius substantially equal to the outer diameter of the part P. However, the lateral posture groove 24 of the outer ring plate 2 can be of any shape that can stably guide the part P in the lateral posture, for example, a V-shaped groove or a U-shaped groove.

  The outer ring plate 2 shown in FIGS. 8 and 9 is provided with lateral posture grooves 24 extending in the circumferential direction. The outer ring plate 2 transports the parts P guided to the lateral posture groove 24 in a posture in the horizontal posture and the center axis thereof in the circumferential direction as shown in FIG. 8, more precisely in the circumferential tangential direction. To do. The outer ring plate 2 guides and moves the laterally-oriented part P to the laterally-oriented groove 24, but transports the vertically-oriented part P without guiding it to the laterally-oriented groove 24 as shown in FIGS. 10 and 11. The parts P that are not guided in the lateral posture grooves 24 are transported in a vertical posture on the upper surface of the outer ring plate 2. The parts P in FIGS. 10 and 11 can be placed on the outer ring plate 2 stably upside down with the upside down. This type of part P has such a size that the bottom area at both ends thereof can be stably placed in a vertical posture. However, in the present invention, as shown in FIG. 12, the part P having a bottom area that can stably stand in the vertical position is also transferred to the vertical position by the outer ring plate 2, and the position selection mechanism 4 is used. Can be selected.

  Since the parts P shown in FIGS. 8 to 11 can be transported in a vertical posture in which both end surfaces thereof are set up vertically, the outer ring plate 2 transports the parts P in four directions. That is, it is transported in two vertical orientations in which the up and down directions are opposite and in two lateral orientations in which the front and rear sides are opposite. The parts shown in FIG. 12 are transferred by the outer ring plate 2 in three directions consisting of a vertical posture in one direction and a horizontal posture in two directions.

  The outer ring plate 2 of FIG. 13 is provided on its upper surface with lateral posture grooves 24 that guide the parts P in a posture in which the central axis is in the horizontal direction at a predetermined interval from the center to the outer side. The outer ring plate 2 is convenient for discharging the elongated parts having different shapes at both ends, for example, the direction of screws and taper rollers. This is because, as shown in the figure, the elongated part P is transferred into the lateral posture groove 24, and the part P in a specific direction can be reliably dropped from the outer ring plate 2 by the posture selection mechanism 4 described later. The outer ring plate 2 in the figure is in a plane including the outer ring plate 2 and is provided with a laterally extending groove 24 extending radially, but the laterally positioned groove is in a plane including the outer ring plate 2. It can also be provided inclined with respect to the radial direction.

  Further, the outer ring plate 2 has the lateral posture groove 24 provided in the circumferential direction by making the width of the lateral posture groove 24 provided outward from the center smaller than the thickness of the part P. In the same way as above, the part P can be transferred in a vertical posture. As shown in FIG. 14, the outer ring plate 2 is provided with a flat portion 25 between the lateral posture grooves 24, or the distance between the lateral posture grooves 24 is compared with the thickness of the part P as shown in FIG. The parts P can be held in the vertical posture on the outer ring plate 2 having the recesses by the horizontal posture grooves 24. The outer ring plate 2 that transfers the parts P in the vertical posture discharges only the parts P in a specific posture as normal posture parts by the posture selection mechanism 4.

  The drive mechanism 3 rotates the outer ring plate 2 and the inner disk 1. The driving mechanism 3 shown in the drawing rotates the inner disk 1 and the outer ring plate 2 together at the same rotational speed. The drive mechanism 3 includes a reduction motor 9 connected to a rotating shaft 8 fixed at the center of the inner disk 1. The reduction motor 9 rotates the inner disk 1 in the direction indicated by the arrow in FIG. The outer ring plate 2 is connected to the frame 10 so as to be rotatable. In the illustrated outer ring plate 2, a disk 12 is fixed to the lower surface via a connecting wall 11, and a cylindrical rotating shaft 13 is fixed to the center of the disk 12. A cylindrical rotary shaft 13 is connected to the frame 10 via a bearing 14 so as to be rotatable, and is connected to the frame 10 so that the outer ring plate 2 can be rotated. Since the outer ring plate 2 and the inner disk 1 are disposed in an inclined posture, the rotation centers of the outer ring plate 2 and the inner disk 1 are relatively inclined.

  The drive mechanism 3 shown in the figure is a single reduction motor 9 that rotates the outer ring plate 2 together with the inner disk 1. In order to rotate the inner disk 1 and the outer ring plate 2 together with the speed reduction motor 9, the inner disk 1 has a drive pin 15 that protrudes from the lower surface fixed thereto. A pair of parallel pins 16 that guide the drive pins 15 are fixed to the outer ring plate 2, and a sliding slit is provided between the parallel pins 16. The parallel pins 16 are fixed toward the center on the upper surface of the disk 12 fixed to the outer ring plate 2. The drive pins 15 are inserted into the sliding slits between the parallel pins 16 so as to move in and out along the parallel pins 16, that is, along the sliding slits. In this drive mechanism 3, the reduction motor 9 rotates the drive pin 15, and the drive pin 15 rotates the outer ring plate 2 via the parallel pin 16. Since the center of rotation of the inner disk 1 and the outer ring plate 2 is inclined with respect to each other, the drive pin 15 rotates the outer ring plate 2 while sliding the sliding slit between the parallel pins 16. Although not shown, the drive mechanism is provided with a sliding slit extending in the radial direction on the inner disk, and a driving pin guided by the sliding slit is fixed to the rotation shaft of the outer ring plate, so that the inner disk and the outer ring plate are connected. You can also rotate together.

  The parts feeder shown in FIGS. 6 and 7 closes the gap between the inner disk 1 and the outer ring plate 2 with a blocking wall 7 in order to prevent the parts P from leaking between the inner disk 1 and the outer ring plate 2. ing. The blocking wall 7 is fixed so as not to rotate. The blocking wall 7 includes a falling wall portion 7A provided in a portion including the rising and falling portion 6 and guide wall portions disposed on both sides of the falling portion 7A and the outer ring plate 2 where the vertical difference is low. 7B. The falling wall portion 7A is used in combination with a drop guide 17 that causes the part P to drop from the outer ring plate 2 to the inner disk 1 at the rising and falling portion 6. The falling wall portion 7 </ b> A in the drawing in which the dropping guide 17 is used in combination is an inclined surface having a downward slope from the outer ring plate 2 toward the inner disk 1. The drop guide 17 allows the part P to drop with little impact and further reduce damage due to the impact. The falling wall portion 7A, which is the dropping guide 17, is made of a synthetic resin such as a fluororesin. The fluororesin drop guide 17 can drop the parts P very smoothly.

  In the parts feeder shown in the drawing, an outer peripheral wall 18 is disposed along the outer peripheral edge of the outer ring plate 2. The outer ring plate 2 having the outer peripheral wall 18 can increase the rotation speed and prevent the parts P from jumping out of the outer ring plate 2 due to centrifugal force and falling. For this reason, this parts feeder can rotate the outer ring plate 2 quickly, and can discharge a large amount of parts P per unit time. However, the outer peripheral wall is not necessarily provided. This is because the parts feeder that rotates the outer ring plate slowly does not cause the parts placed on the outer ring plate to fall outward due to acceleration.

  Further, the parts feeder shown in FIG. 6 is provided with a supply guide 19 that supplies the outer ring plate 2 in order to smoothly supply the parts P supplied on the inner disk 1. The supply guide 19 is fixed so as not to rotate. The parts feeder shown in the figure is provided with two supply guides 19. The first supply guide 19 </ b> A is provided in the central portion of the inner disk 1. The second supply guide 19B is disposed outside the first supply guide 19A. The supply guide 19 is inclined with respect to the radial direction of the inner disk 1 so that the part P can be transferred to the outside by the rotation of the inner disk 1. That is, the supply guide 19 is inclined in the rotational direction with respect to the radial direction of the inner disk 1 from the center toward the outer periphery. The distal end portion of the second supply guide 19 </ b> B extends to above the outer ring plate 2. This is because the parts P transferred to the outside along the second supply guide 19B are transferred onto the outer ring plate 2.

  This structure is the simplest structure and can transfer the part P of the inner disk 1 to the outer ring plate 2. However, the present invention does not specify a mechanism for transferring the part P of the inner disk 1 to the outer ring plate 2 in the supply guide 19 shown in the drawing. It is possible to transfer parts from the inner disk to the outer ring plate by air flow, or to transfer parts made of magnetic material from the inner disk to the outer ring plate using magnetic attraction and repulsion. It is.

  The parts P transferred from the inner disk 1 to the outer ring plate 2 may be stacked and transferred. In the illustrated parts feeder, the destacking material 20 is disposed in the transfer path of the outer ring plate 2 so that the parts P are transferred without being stacked. The delamination material 20 makes the space | interval of a lower end edge and the upper surface of the outer side ring board 2 the clearance gap through which only one-stage parts P can pass. Further, the destacking material 20 transfers the part P of the outer ring plate 2 to the inner disk 1 in a posture inclined with respect to the radial direction. In other words, the part P is inclined with respect to the radial direction in a direction in which the part P can be transferred from the outer ring plate 2 to the inner disk 1. Therefore, when two or more stages of parts P are transferred on the outer ring plate 2, only the first-stage parts P are allowed to pass, and the parts P transferred on the first-stage parts P are transferred. Then, it is discharged from the outer ring plate 2 to the inner disk 1. Therefore, the parts P transferred on the outer ring plate 2 always pass through the destacking material 20 and become one step. This mechanism is a simple mechanism, and the parts P that are stacked and transferred on the outer ring plate 2 can be arranged in one stage. However, the parts transferred on the outer ring plate can be detected by an optical sensor, and the parts transferred on the first stage part by airflow or the like can be removed.

  Further, the parts feeder of FIG. 6 is provided with a one-line guide 21 for arranging parts P transferred by the outer ring plate 2 in a line. The one-row guide 21 is arranged in the transfer path of the parts P transferred by the outer ring plate 2 and transfers the parts P transferred in a row in two or more rows. The one-row guide 21 discharges the parts P, which are transferred in two or more rows at the tip, from the outer ring plate 2 to the inner disk 1. Therefore, the distance between the front edge of the one-line guide 21 and the inner peripheral edge of the outer ring plate 2 is adjusted so that only one line of parts P can be transferred.

  The parts feeder shown in the drawing passes the parts P supplied from the inner disk 1 to the outer ring plate 2 through the destacking material 20 to form one stage, and further passes through the one-line guide 21 to transfer to the ascending and dropping unit 6 as one line. . In the ascending / falling section 6, the posture selection mechanism 4 detects the direction of the part P, and drops the abnormal posture part in the opposite posture from the outer ring plate 2 to the inner disk 1. The posture selection mechanism 4 passes the normal direction parts in a normal posture without dropping from the outer ring plate 2 and discharges them to the outside.

  The parts feeder shown in the figure has a sorting guide 22 as a posture sorting mechanism 4 in the ascending / falling portion 6 of the outer ring plate 2. The illustrated posture selection mechanism 4 includes a first selection guide 22A and a second selection guide 22B. These sorting guides 22 have a sorting unit 22a that sorts normal posture parts and non-normal posture parts in contact with the parts P transferred in the postures shown in FIGS. The sorting unit 22a of the sorting guide 22 shown in these figures allows the normal posture parts to pass but drops the abnormal posture parts. The posture selection mechanism 4 shown in FIG. 17 is a part that is transported in a vertical posture with the opening facing upward, and the part in the posture (1) in FIG. 3 is discharged as a normal posture part. To do.

  The first sorting guide 22A sorts the parts P transferred in the vertical posture. The parts P that are transferred in a vertical posture pass the one with the opening facing upward, and drop the one with the opening facing downward from the outer ring plate 2. The part P in the figure has an outer diameter at one end larger than the other end. As shown in FIG. 18, the first sorting guide 22 </ b> A has a sorting unit 22 a that pushes out the part P, which is transferred in a vertical posture with the opening portion downward, from the outer ring plate 2. As shown in FIG. 17, the sorting portion 22a of the first sorting guide 22A is inserted into the chamfered portion at the bottom of the part P that is moved upward through the opening, thereby reducing the amount of extrusion of the part P in this posture. . Therefore, the part P transferred in this posture has a center of gravity located above the outer ring plate 2 and does not fall from the outer ring plate 2. Since the parts transferred in the opposite posture are not chamfered at the periphery of the opening end, they are pushed out by the sorting unit 22a as shown in FIG. The part P pushed out to this position falls to the inner disk 1 with the center of gravity shifted to the inside of the outer ring plate 2. Furthermore, as shown in FIG. 19, the first sorting guide 22 </ b> A does not drop the parts P transferred in the horizontal posture from the outer ring plate 2. This is because the laterally oriented part P has a circular outer shape and is not pushed out until it is dropped by the sorting unit 22a.

  The second sorting guide 22 </ b> B drops the part P in the lateral posture from the outer ring plate 2. The part P in the figure is higher when in the horizontal posture than in the vertical posture. As shown in FIG. 19, the second sorting guide 22B has a sorting portion 22a that is guided by the lateral posture groove 24 and abuts on the upper part of the part P that is transferred to the lateral posture. As shown in the plan view of FIG. 16, the sorting unit 22 a is inclined in a direction to drop the part P onto the inner disk 1 when the part P is transferred by the outer ring plate 2. Therefore, when the upper part of the part P comes into contact with the sorting part 22a, the part P is dropped from the outer ring plate 2 by the second sorting guide 22B. The second sorting guide 22B drops the part P having a lateral posture regardless of the front-rear direction.

  Further, the parts feeder shown in FIG. 16 is provided with a raising piece 26 that raises the parts P, which are transferred with the opening portion forward, from a horizontal posture to a vertical posture so that the opening portion faces upward. The part P passes through the raising piece 26 and then passes through the sorting guide 22. Therefore, the raising piece 26 is disposed in front of the sorting guide 22. As shown in FIG. 20, the raising piece 26 extends from the top to the bottom and bends the lower end forward to form a hooking portion 26a. The hooking portion 26a is inserted into the part P transferred by the outer ring plate 2 from the opening. When the part P is transferred in this posture, as shown by the chain line in the figure, the raising piece 26 hooks the opening edge of the part P and raises the opening portion in an upward direction. That is, the posture of the normal posture part is set. The parts P in the normal posture pass through the first sorting guide 22A and the second sorting guide 22B, and are discharged to the outside by the outer ring plate 2. Thus, the apparatus which makes the part P the normal posture part by the raising piece 26 can efficiently discharge the part P as the normal posture part.

  The parts feeder provided with the posture selection mechanism 4 of FIGS. 16 to 19 specifies and discharges the parts P in one posture. This parts feeder has the feature that the post-processing of the discharged parts P can be efficiently and easily performed. However, the parts feeder of the present invention is not necessarily specified as one that discharges one posture of a part as a normal posture part. For example, as shown in FIG. 4, a part connecting a thick part and a thin part with the same central axis falls from the outer ring plate 2 with three directions as normal posture parts and a specific posture as an abnormal posture part. It can also be made.

  The posture selection mechanism 4 is designed in an optimum shape depending on the shape of the part P and the posture of the normal posture part. The parts P shown in FIG. 4 can be discharged as normal posture parts by the following posture selection mechanism 4. The posture selection mechanism 4 discharges only the part P in the posture (1) in FIG. 4 as an abnormal posture part and discharges the parts P in the postures (2) to (4) as normal posture parts. Parts P discharged in the horizontal posture shown in (3) and (4) can be aligned to the posture of (2) by connecting the raising mechanism to the discharge side.

  The posture selection mechanism 4 that discharges the three directions of the parts P as normal posture parts has the same structure as the first selection guide 22A of FIG. The sorting guide of this posture sorting mechanism is arranged at the outer edge of the outer ring plate 2 so as to push the part P from the outer ring plate 2 to the inner disk 1 in the same manner as the sorting guide 22 of FIG. As shown in FIG. 21, the sorting guide 22 removes only the part in the vertical posture with the thick part on the lower side from the outer ring plate as an abnormal posture part and drops it on the inner disk. The parts transferred in the postures of FIGS. 22 and 23, that is, the part P in the vertical posture with the thick part on the upper side and the part P in the horizontal posture are discharged as normal posture parts. Therefore, the sorting part 22a of the sorting guide 22 pushes out the thick part in the vicinity of the upper surface of the outer ring plate 2 so that the vertical part P with the thick part on the lower side is dropped from the outer ring plate 2. And projecting toward the center of the outer ring plate 2 until the parts P become unbalanced and fall.

  FIG. 24 shows a raising mechanism 27 for the part P. The raising mechanism 27 aligns the parts P in the horizontal posture discharged in a downward gradient in a vertical posture with the thick part up. In this raising mechanism 27, a hooking step material 28 is arranged in the transfer path of the part P, and a parallel slit 29 is provided in front of the raising part 27 for inserting a thin portion and locking a thick portion. The hooking step material 28 is provided with a step 28a so as to become lower in the direction in which the parts P are transferred. The parallel slit 29 extends toward the catching step material 28 so as to lock a thick part of the part P that slides down the catching step material 28. The raising mechanism 27 is a very simple mechanism, and discharges the parts P in the horizontal position from the parallel slits 29 in the vertical position with the thick part up as follows.

  As shown by the solid line in the figure, the thin part P is moved forward, the thin part slides down the step 28a of the catching step material 28, rotates about 90 degrees clockwise in the figure, and the thick part is parallel. It becomes a vertical posture with the thick part on top by being hooked on the slit 29. As shown by the chain line in the figure, the part P transferred forward with the thick part slides down the step 28a of the catching step material 28 while the thick part is caught by the parallel slit 29, and the counterclockwise direction Rotate 90 degrees to a vertical posture with the thick part up, and the paper is discharged by the parallel slit 29. The raising mechanism 27 described above is a very simple mechanism, and discharges the parts in the horizontal posture with the front and rear opposite directions in the vertical posture with the thick part up.

  Furthermore, although not shown in the figure, the vertical part with the thick part on the upper side slides down along the transfer path in the same posture, the thin part of the part is guided inside the parallel slit, and the thick part of the part is It is in a state of being caught by the parallel slits and discharged in a vertical posture with the thick part on top.

  As described above, the raising mechanism 27 discharges the parts P discharged from the posture selecting mechanism 4 with the three directions as normal posture parts aligned in a vertical posture with the thick part up.

  Further, the parts feeder including the outer ring plate 2 shown in FIG. 13 uses the posture selection mechanism 4 to select and specify the horizontal posture parts P transferred by the horizontal posture groove 24 provided on the upper surface of the outer ring plate 2. The part P in the direction of is dropped from the outer ring plate 2. As shown in FIGS. 25 and 26, the posture selection mechanism 4 includes a selection guide 22 having a selection portion 22a that comes into contact with a part P transferred in a horizontal posture. The sorting unit 22a of the sorting guide 22 shown in these drawings allows the normal posture part to pass but drops the abnormal posture part. The posture selection mechanism 4 passes the parts in the posture shown in FIG. 25, that is, the parts transferred in a posture with the thick end portion outside, without dropping as normal posture parts, and the parts in the posture shown in FIG. Parts that are transported in a posture with the thick end portion inside are dropped from the outer ring plate 2 as non-normal posture parts.

  As shown in FIGS. 26 and 27, the parts of the elongated parts having different shapes at both ends are shifted in the center of gravity to the end side thicker than the center in the axial direction. The posture selection mechanism 4 uses the deviation of the center of gravity position to select the elongated parts that are transferred in the horizontal posture. That is, the posture selection mechanism 4 pushes out the parts P transferred in the horizontal posture in the inner direction of the outer ring plate 2 by the selection portion 22a of the selection guide 22. Even if it is an abnormal posture part, it is constant. As shown in FIG. 26, the part P transferred in a lateral posture with the thick part outside is located above the outer ring plate 2 and does not fall from the outer ring plate 2. On the other hand, the part P transferred in the lateral posture with the thick part inside is shifted from the outer ring plate 2 with the center of gravity shifted to the inside of the outer ring plate 2 as shown in FIG. The sorting guide 22 drops the abnormal posture part from the outer ring plate 2, but specifies the extrusion amount of the part P so that the normal posture part can pass without dropping. That is, when the sorting portion 22a of the sorting guide 22 pushes out the thick portion in the vicinity of the upper surface of the outer ring plate 2 so that the abnormal posture part with the thick portion inside is dropped from the outer ring plate 2, The part P protrudes toward the center of the outer ring plate 2 until it becomes unbalanced and falls.
