Description

  The present invention relates to a parts feeder that discharges by aligning directions of directional parts.

  A parts feeder is used as a device that discharges the directional parts with the same direction. 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.

  In addition, a parts feeder that transfers parts by vibration also requires a special mechanism in order to discharge the directional parts in the same direction. For this reason, the structure and mechanism of a parts feeder that discharges directional parts with the same direction, such as a flanged bearing, are considerably complicated.

The present invention was developed for the purpose of solving the drawbacks of such conventional parts feeders. An important object of the present invention is to provide a parts feeder that can transfer various parts quickly and efficiently, and can significantly reduce the noise level while minimizing damage during transfer.
Another important object of the present invention is to provide a parts feeder that can discharge a directional part with a simple mechanism.

The parts feeder of the present invention includes an inner disk 1 that is arranged to be rotatable in a horizontal or substantially horizontal plane, and an outer side that is disposed outside the inner disk 1 in a posture inclined with respect to the inner disk 1. The ring plate 2, the drive mechanism 3 that rotates the outer ring plate 2 and the inner disk 1, and the parts P supplied on the inner disk 1 are transferred to the outer ring plate 2 by the rotation of the inner disk 1. And a supply guide 19 to be supplied . 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. The rotating outer ring plate 2 discharges the part P to the outside.

  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. The parts feeder inclines the outer ring plate 2 from the supply unit 5 toward the ascending / falling unit 6 and inclines the inner disk 1 from the supply unit 5 toward the ascending / falling unit 6 of the outer ring plate 2. Can be tilted. Furthermore, the parts feeder of this invention can arrange | position the inner side disk 1 in a horizontal surface, and can incline the outer side ring board 2 to the ascending / falling part 6 from the supply part 5 toward the ascending / falling part 6. FIG. Furthermore, in the parts feeder of the present invention, the outer ring plate 2 can be disposed horizontally, and the inner disk 1 can be inclined downwardly from the supply unit 5 toward the rising and dropping unit 6 of the outer ring plate 2. .

  The drive mechanism 3 rotates the inner disk 1 and the outer ring plate 2 in the same direction at the same rotation speed. The parts feeder can discharge the directional parts P in the same direction. The directional part can be a part P having a heel at one end or one end. The directional part P can be a flanged bearing or an outer ring of a flanged bearing. Furthermore, the directional part P can be a frustoconical part having a tapered side surface.

  Furthermore, the parts feeder of the present invention can be provided with a sorting guide 22 as the posture sorting mechanism 4 in the ascending / falling portion 6 of the outer ring plate 2. The sorting guide 22 has a sorting surface 22A for sorting by contacting the part P transferred by the outer ring plate 2. The sorting guide 22 can be provided with a non-contact portion 23 through which the outer peripheral protrusion T of the part P passes on the sorting surface 22A. In the sorting guide 22, the forward-direction part P ′ transferred by the outer ring plate 2 passes the outer peripheral protruding portion T through the non-contact portion 23 and is not dropped from the outer ring plate 2 to the inner disk 1. The reverse direction part P ″, which is placed on the plate 2 and discharged to the outside and transferred by the outer ring plate 2, is pushed from the outer ring plate 2 to the inner disk 1 by the outer peripheral projection T being pushed by the sorting surface 22 A of the sorting guide 22. The sorting guide 22 can have a structure capable of adjusting the size of the reverse direction part P ″ to be dropped from the outer ring plate 2.

  Furthermore, the parts feeder of the present invention arranges the one-line guide 21 for arranging the parts P in a line in the transfer path of the parts P transferred by the outer ring plate 2, and selects the parts P that have passed through the one-line guide 21. It can be passed through the guide 22. The one-line guide 21 can be adjustable. Furthermore, the parts feeder of the present invention can arrange a drop guide 17 for dropping the parts P between the rising and falling part 6 of the outer ring plate 2 and the inner disk 1.

In this specification, the “directional part” means that the outer peripheral surface has an outer peripheral protruding portion that protrudes outward, and the outer peripheral protruding portion has an asymmetric shape with respect to the center of the outer peripheral surface. And it shall mean the part of a shape where a direction is specified by this outer periphery protrusion part. Therefore, this part is equivalent to the outer peripheral protrusion in parts with one end or one end part, and the outer peripheral part on the wide bottom side is equivalent to the outer peripheral protrusion part in the truncated cone-shaped part whose side surface is a tapered surface. To do.
Furthermore, a directional part is not specified as a part having an outer peripheral protrusion provided continuously on the outer peripheral surface. A directional part may be a part in which an outer peripheral protrusion is provided on the outer peripheral surface.

  The parts feeder of the present invention has a feature that parts can be discharged by a simple mechanism. In particular, the parts feeder of the present invention has features that it can transfer various parts quickly and efficiently, and can significantly reduce the noise level while minimizing damage during transfer. That is, the parts feeder of the present invention rotates the inner disk and the outer ring plate, which are arranged in an inclined posture, and transfers directional parts, and the parts are discharged by the outer ring plate. Because. Since the parts feeder of this structure transfers parts without giving vibrations as in the prior art, damage during transfer can be minimized and the noise level can be reduced. In addition, since the parts feeder of the present invention transfers parts by the rotating inner disk and the outer ring plate, various parts can be transferred quickly.

  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 FIG. 1 and FIG. 2 discharges a directional part P whose direction is specified by the outer peripheral protruding part, like a bearing with a flange, in a uniform direction. The directional part P which the parts feeder of the present invention transports is not specified as a brazed bearing. The parts feeder of the present invention can discharge, for example, parts with a ridge at one end in the same direction.

  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 that rotates the inner disk 1, and a posture selection mechanism 4 that drops the reverse part P ″ transferred in the reverse direction 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. 2, both the inner and outer ring plates are tilted in the opposite direction, or the inner disk is leveled and only the outer ring plate is tilted. The inner disk 1 is tilted with the ring horizontal.

  As shown in FIG. 2, 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 P 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. 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. The parts feeder shown in FIGS. 1 and 2 closes the gap between the inner disk 1 and the outer ring plate 2 with a blocking wall 7 so that the part P does not leak from this gap. The blocking wall 7 is fixed so as not to rotate.

  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 rod 11, and a cylindrical rotary 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. 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 pin 15 is inserted between the parallel pins 16 so as to be able to move in and out along the parallel pins 16. 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 between the parallel pins 16.

  The blocking wall 7 of the parts feeder shown in FIG. 1 is arranged on the falling wall portion 7A provided on the portion including the rising and falling portion 6 and on the lower side of the inner disk 1 and the outer ring plate 2 on both sides thereof. And a guide wall portion 7B provided. 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 can drop the parts P with little impact and further reduce damage caused by 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 2 slowly does not cause the parts P placed on the outer ring plate 2 to fall outward due to acceleration.

  Further, the parts feeder shown in FIG. 1 is provided with a supply guide 19 for supplying the parts P supplied on the inner disk 1 to the outer ring plate 2. 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 outer ring plate 2 upper surface the clearance gap which only one step part 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. 1 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 reverse direction part P ″ in the reverse posture from the outer ring plate 2 onto the inner disk 1. The posture selection mechanism 4 The normal direction part P ′ in a normal posture is allowed to pass through without dropping from the outer ring plate 2 and discharged 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. As shown in FIGS. 3 to 6, the sorting guide 22 has a sorting surface 22 </ b> A that contacts the part P transferred by the outer ring plate 2 and sorts the forward direction part P ′ and the backward direction part P ″. The sorting guide 22 shown in these figures is provided with a non-contact portion 23 on the sorting surface 22A through which the outer peripheral protruding portion T of the forward direction part P ′ passes.The sorting guide 22 of FIGS. A non-contact portion 23 for allowing a bag, which is an outer peripheral protruding portion T of the part P, to pass therethrough is provided between the plate 2 and the sorting guide 22 in FIGS. 5 and 6 is provided with a non-contact portion 23 on the upper side. The sorting guide 22 shown in FIG. 4 places the forward-direction part P ′ transferred on the outer ring plate 2 with the heel down on the outer ring plate 2 without dropping from the outer ring plate 2 to the inner disk 1. The sorting guide 22 in FIG. The forward part P ′ transferred on the side ring plate 2 is discharged from the outer ring plate 2 onto the outer ring plate 2 without dropping from the outer ring plate 2 to the inner disk 1. The outer peripheral protrusion T is a non-contact portion. 3, the sorting guide 22 in FIG. 3 moves the reverse part P ″ transported by the outer ring plate 2 with the ridge, which is the outer peripheral protruding portion T, on the sorting surface 22A of the sorting guide 22. Press to drop from the outer ring plate 2 to the inner disk 1. The sorting guide 22 in FIG. 5 pushes the reverse part P ″, which is transferred by the outer ring plate 2 with the ridge, which is the outer peripheral protruding portion T, downward, by the sorting surface 22A of the sorting guide 22 and then from the outer ring plate 2 Drop it into 1.

  The sorting guide 22 causes the reverse part P ″ to drop from the outer ring plate 2 to the inner disk 1 because the sorting surface 22A of the sorting guide 22 has an outer peripheral protrusion T as shown in the enlarged views of FIGS. This is because the center of gravity of the part P is on the inner side of the inner peripheral edge of the outer ring plate 2 and not above the outer ring plate 2. Further, the forward direction part P ′ is not on the outer ring plate 2. As shown in the enlarged views of FIG. 4 and FIG. 6, the heel that is the outer peripheral protruding portion T of the forward direction part P ′ is not contacted with the sorting surface 22A of the sorting guide 22 This is because the center of gravity of the part P is located between the inner peripheral edge and the outer peripheral edge of the outer ring plate 2 and above the outer ring plate 2 because the part 23 is moved.

  The posture selection mechanism 4 having this structure is a very simple mechanism, and can drop only the forward part P ′ by dropping the backward part P ″ from the outer ring plate 2 onto the inner disk 1. The center of gravity of the part P is dropped from the upper side of the outer ring plate 2, and the center of gravity is positioned above the outer ring plate 2 without pressing the heel of the positive direction part P '. This is because the outer ring plate 2 is not dropped onto the inner disk 1.

  The posture selection mechanism 4 shown in FIG. 3 to FIG. 6 selects a part P having a hook as an outer peripheral protrusion T at one end as a directional part P. However, as shown in FIG. 7 and FIG. 8, the directional part can be a part P having a flange which is an outer peripheral protruding portion T at a position shifted from the center of the side surface to the end. Also in the posture selection mechanism 4 shown in these drawings, the forward direction part P ′ transferred by the outer ring plate 2 causes the outer peripheral protruding portion T to pass through the non-contact portion 23 of the selection surface 22A and is dropped onto the inner disk 1. The outer peripheral protruding portion T of the reverse direction part P ″ is pushed by the selection surface 22A of the selection guide 22 and dropped from the outer ring plate 2. The posture selection mechanism 4 includes the part P The vertical position of the sorting guide 22 and the interval between the non-contact portions 23 are adjusted according to the position of the wrinkles.

  Furthermore, as shown in FIGS. 9 and 10, the directional part P can be a truncated cone-shaped part P whose side surface is a tapered surface. In this part P, the outer peripheral portion on the bottom surface side of the truncated cone having a large outer diameter is projected outwardly from the outer peripheral portion on the bottom surface side having a small outer diameter to form an outer peripheral protruding portion T. The posture selection mechanism 4 shown in these drawings places the forward-direction part P ′, which is transferred by the outer ring plate 2 with the outer peripheral projection T on the lower side, on the outer ring plate 2 without dropping it on the inner disk 1. The reverse part P ″ that is discharged to the outside and transported with the outer peripheral projection T on the upper side is pushed by the sorting guide 22 and dropped from the outer ring plate 2.

  In the sorting guide 22 shown in the figure, the surface that contacts the side surface of the part P is an inclined surface 22A that follows the tapered surface of the part P. As shown in FIG. 9, when the reverse direction part P ″ is supplied, the sorting guide 22 pushes the outer peripheral protrusion T on the upper surface of the inclined surface 22 </ b> A so that the position of the center of gravity of the part P is from above the outer ring plate 2. In addition, when the forward direction part P ′ is supplied, the tapered surface of the side surface is set along the inclined surface 22A, and the center of gravity is positioned above the outer ring plate 2 to the outer ring plate 2. However, the posture selection mechanism for selecting the frustoconical part does not necessarily have an inclined surface at the tip of the selection guide, as shown in FIGS. When the guide is separated from the outer ring plate and a non-contact part is provided, and the forward direction part is supplied, the outer peripheral protruding part is passed through the non-contact part and the reverse part is supplied. Press outside with the sorting guide This is because it is also possible to drop from the ring plate.

  Further, although not shown, the directional part may be a part other than a circle, for example, a part such as a square, a rectangle, a polygon, and an ellipse. The parts feeder that sorts out parts of these shapes is preferably a part-line guide or a part that is transported in a predetermined position by specifying the horizontal position of the part with a direction guide provided separately from the one-line guide. The direction of the is sorted with the sorting guide. For example, in the case of a rectangular part, the side of the long side can be transferred in a posture facing the sorting guide, and the orientation of the part can be sorted using the sorting guide described above.

  In the above embodiment, the sorting guide 22 is used as the posture sorting mechanism 4. This posture selection mechanism 4 is an extremely simple mechanism and has the feature that the reverse direction part P ″ and the normal direction part P ′ can be selected. However, the parts feeder of the present invention can change the posture of the reverse direction part and the normal direction part. A part that is recognized as a reverse part can be removed by dropping it from the outer ring plate to the inner disk by airflow.
