  The parts feeder described in Japanese Patent Application Laid-Open No. 2000-159327 is provided with a spiral component conveying plate along the inner wall of a circular vibrating bowl, and an oil hole is formed at the center in the width direction of the component conveying plate. Has been.

JP 2000-159327 A

  The oil hole described in the above-mentioned patent document is formed in the center portion when viewed in the width direction of the component conveying plate, and the oil liquid that has passed through the oil hole drops and flows to the lower side in the vibrating bowl. However, no measures are taken with respect to the treatment of the oil liquid in the delivery passage structure portion that is continuous with the component conveying plate and guides the component to the outside of the vibrating bowl. Therefore, the oil liquid in the delivery passage structure portion flows out of the parts feeder, and the problem of oil contamination occurs on the base plate and related equipment arranged in the vicinity of the parts feeder.

  The present invention has been provided to solve the above-described problems. In the vibratory parts feeder, the oil liquid in the delivery passage structure that guides the parts to the outside of the vibratory bowl is collected, and the oil liquid is collected at a predetermined location. The purpose is to guide.

The invention described in claim 1
A spiral-shaped component conveying plate is provided inside the outer wall plate of the circular vibrating bowl, and a delivery passage structure portion is provided for sending the component out of the vibrating bowl in a state continuous with the component conveying plate. In the form of
The delivery passage structure portion includes at least a passage member that delivers parts in a predetermined posture, a receiving groove member that collects the oil flowing down from the passage member, and an outflow of oil provided in the receiving groove member. It is a parts feeder characterized by being provided with holes.

  The delivery passage structure portion includes at least a passage member that delivers parts in a predetermined posture, a receiving groove member that collects the oil flowing down from the passage member, and an oil liquid outflow hole provided in the receiving groove member Is provided. In the passage member, when the component is a projection nut having a welding projection, the welding projection is aligned in a predetermined vertical direction and is sent out in the form of a front and back. When the component is a bolt having a head, the component is sent out in a suspended state with the head locked.

  An oil film such as rust preventive oil applied to the component gradually flows down from the surface of the component, and tends to accumulate in a liquid state at the bottom and corner portions of the passage member. Thus, the oil liquid stagnated in the passage member flows down from the passage member and is collected in the receiving groove member. Thereafter, the oil liquid is discharged from an outflow hole provided in the receiving groove member and is stored in a predetermined storage container. Therefore, in the delivery passage structure portion, a passage member that delivers the components in a predetermined posture, that is, a component delivery function, a collection function that collects the oil flowing down from the passage member by the groove member, and a receiving groove member The discharge function of discharging the oil liquid from the outflow hole is performed.

  As described above, the oil film applied to the parts delivered from the vibrating bowl becomes liquid and is collected in the receiving groove member and discharged from the outflow hole. For this reason, the oil liquid does not fall on the base plate and related equipment in the vicinity of the parts feeder from the delivery passage structure, and oil contamination in the vicinity can be reliably prevented. By tilting the receiving groove member, the oil liquid can be collected in one place and stored in a storage container or the like through the outflow hole. Therefore, the oil liquid is concentrated only at a predetermined location, which is effective in terms of factory cleaning management.

  Furthermore, even if the oil film of the component becomes liquid and stagnates on the component transport plate, the oil liquid is transferred from the component transport plate to the passage member of the delivery passage structure part that continues from the component transport plate by the vibration of the vibratory bowl. Is done. The oil liquid liquefied in the vibrating bowl is collected intensively in the delivery passage structure. In other words, since it is collected in the delivery passage structure, which is the final position of the component transfer, all fluid oil in the vibrating bowl is collected in the delivery passage structure, and is sent to harmful places. Leakage can be prevented. In other words, the rust preventive oil applied to the components is sent out in a state where only the minimum required oil film is formed, so that dripping of the oil liquid or the like can be avoided.

The invention according to claim 2
The component to be sent out is a shaft-shaped component having a shaft and a head,
A spiral-shaped component conveying plate is provided inside the outer wall plate of the circular vibrating bowl, and a delivery passage structure portion is provided for sending the component out of the vibrating bowl in a state continuous with the component conveying plate. In the form of
In the delivery passage structure portion, a passage space for allowing the shaft portion to pass between the passage member and the guide plate continuing to the component conveying plate and for locking the head is formed in a state continuous to the component conveying plate. And
The inclination angle of the guide plate is set so that the inclination angle of the shaft portion gradually approaches the vertical direction toward the moving direction of the component,
A parts feeder characterized in that a receiving groove member for collecting the oil liquid flowing down on the guide plate is provided at a lower edge of the guide plate, and an oil liquid outflow hole is provided in the receiving groove member. is there.

  When the shaft-shaped component that has been transferred to the component conveying plate by the vibration of the bowl reaches the passage space that continues to the component conveying plate, that is, at the stage where the shaft-shaped component starts to reach the delivery passage structure, Passes through the passage space, and the tip of the shaft part is lowered to the lower side by the weight of the shaft part. On the other hand, the head cannot pass through the passage space and is in a suspended state (neck hanging state). Thus, at the initial stage of reaching the passage space, the inclination angle of the guide plate is large and the shaft portion has a large inclination angle close to the horizontal direction. At this time, when the oil liquid adhering to the shaft-shaped part falls on the guide plate, the oil liquid flows down on the guide plate, flows into the receiving groove member, and is further discharged from the outflow hole to a predetermined location. .

  Furthermore, when the shaft-like component suspended from the bowl is transferred, the shaft portion gradually changes to an inclination angle approaching the vertical direction. Even at this stage, the oil is discharged in the same manner as described above.

  Furthermore, when the suspended shaft-like component is transferred by the vibration of the bowl, the shaft portion assumes a substantially vertical hanging posture and is sent out in this posture. Even at this stage, the oil is discharged in the same manner as described above. That is, the oil liquid is collected and discharged until the shaft-like component is separated from the delivery passage structure.

  Therefore, between the passage plate and the guide plate continuing to the component conveying plate, the passage of the shaft portion is allowed and the passage space for locking the head is formed continuously with the component conveying plate. The shaft portion of the shaft-shaped component that has moved the transport plate smoothly enters the passage space, and is surely suspended, so that the shaft-shaped component is transferred in the correct posture.

  At the same time as changing the conveying posture of the shaft-like component in the vertical direction, the oil liquid is reliably collected and discharged. Since the shaft part of the suspended shaft-shaped part is guided by a guide plate whose inclination angle gradually changes, the posture change of the shaft-shaped part and the treatment of the oil liquid are achieved at the same time, and a parts feeder with excellent functionality is achieved. Yeah. Since the receiving groove member is provided at the lower edge of the guide plate, it is possible to reliably capture the oil and completely prevent the nearby oil stains.

  As the transfer of the shaft-shaped parts progresses, the direction of the guide plate and the shaft portion approaches the vertical direction, so the flow of the oil adhering to the surface of the shaft portion and the guide plate is more aggressive. As a result, more oil is captured by the receiving groove member.

  In the initial stage when the shaft-shaped component reaches the passage space, the inclination angle of the guide plate is large and the shaft portion has a large inclination angle close to the horizontal direction, so that the shaft-shaped component is smooth from the component conveying plate to the guide plate. Can be migrated to. Since the shaft-shaped parts are long, it is difficult to change the direction suddenly. However, since the inclination angle of the guide plate is increased in the initial stage, the turning angle of the shaft-shaped parts is decreased. Smooth turning is possible, and reliable and reliable component behavior can be ensured.

It is the top view and sectional drawing of the whole parts feeder. It is sectional drawing of the principal part. It is sectional drawing which shows the modification of a delivery channel | path structure part. It is the top view which shows another Example, and sectional drawing of each part.

  Below, the form for implementing the parts feeder of this invention is demonstrated.

  1 to 3 show a first embodiment of the present invention.

  First, components will be described.

  There are various parts such as bolts, nuts, washers, and shafts that are sent out from a parts feeder having a vibrating bowl. Here, the nuts shown in FIG. 2 and the bolts shown in FIG.

  Next, the projection nut will be described.

  The component shown in FIG. 2 is a projection nut 4 to which electric resistance welding is performed. A screw hole is formed in the center of the square body, and welding projections 5 are provided at four corners on one side. In the following description, the projection nut may be simply expressed as a nut.

  Next, the parts feeder will be described.

  The parts feeder is indicated by reference numeral 100. A spiral component conveying plate 3 is provided inside the outer wall plate 2 of the circular vibrating bowl 1. In order to bring the nut 4 close to the inner surface of the outer wall plate 2, the component conveying plate 3 is provided with a lower inclination on the outer wall plate 2 side, which is indicated by an inclination angle θ1 in FIG.

  Since the height of the spiral component conveying plate 3 gradually increases in the counterclockwise conveying direction, the outer wall plate 2 and the component conveying plate 3 are stepped as shown in FIG. The component conveying plate 3 has a two-stage shape in the B-B cross section. Reference numeral 6 denotes a bottom plate of the vibrating bowl 1. Moreover, the BB cross section of FIG. 1 (A) is the (B) figure of the same figure. The same applies to FIG.

  The components transferred on the component conveying plate 3 are in various orientations such as a landscape orientation, a portrait orientation, and an inverted state. In order to align these component postures in a predetermined direction, a posture control unit is arranged, which is denoted by reference numeral 13. That is, as shown to FIG. 2 (B), in the attitude | position control part 13, the welding protrusion 5 of the nut 4 is sent out aligning upwards. Moreover, if it is a bolt with a head, a bolt will be suspended and sent out.

  A combined vibration in the circumferential direction and the vertical direction is applied to the vibrating bowl 1 as described above, and the nut 4 is transferred on the component conveying plate 3 in the counterclockwise direction. In order to impart vibration, a vibration unit (not shown) is installed below the bowl.

  Next, the delivery passage structure will be described.

  A delivery passage structure 7 is formed for delivering the nut 4 to the outside of the vibrating bowl 1 in a state continuous with the component conveying plate 3. Various delivery passage structures 7 are adopted depending on the shape of the parts. At least a passage member 8 for delivering the nut 4 in a predetermined posture and a receiver for collecting the oil flowing down from the passage member 8. A groove member 9 and an oil solution outflow hole 10 provided in the receiving groove member 9 are provided.

  Since the part is the projection nut 4, the passage member 8 is an elongated member having a U-shaped cross section opened upward. The bottom plate 11 of the passage member 8 is provided with a slope that is lowered on one side, which is indicated by the slope angle θ2 in FIG. An oil drain passage 12 is provided on the lower side of the bottom plate 11. The oil drainage passage 12 is implemented in various shapes such as a circular hole and a slender passage space of the bolt shaft portion, and plays the role of causing the oil liquid in the passage member 8 to flow downward. Here, it is a circular hole 12 opened at the end of the bottom plate 11. The oil that has passed through the oil drain passage 12 is collected by the receiving groove member 9.

  In the first embodiment, the surface of the component conveying plate 3 is smoothly continuous with the surface of the bottom plate 11 of the passage member 8.

  The receiving groove member 9 has a U-shaped cross section opened upward, but it may be an arc-shaped cross section or a V-shaped cross section. As shown in FIG. 2 (A), an end plate 15 is welded to the end of the receiving groove member 9 so that the oil does not spill.

  The position of the receiving groove member 9 may be set directly below the oil discharging passage 12 so that the oil liquid flowing out or dripping from the oil discharging passage 12 is received by the receiving groove member 9 from below. 14 is provided. As shown in FIG. 2B, a flat guide plate 14 is welded to the lower end of the passage member 8, and a receiving groove member 9 is formed at the lower portion of the guide plate 14. The guide plate 14 is composed of an inclined steel plate, and the oil liquid that has flowed out of the oil drain passage 12 flows down along the surface of the guide plate 14 and flows into the receiving groove member 9.

  Here, the receiving groove member 9 is formed by bending the lower side of the guide plate 14 into a groove shape, but only the receiving groove member 9 is made separately and welded along the lower edge of the guide plate 14. May be.

  By using such a guide plate 14, the oil liquid flowing down from the oil discharge passage 12 flows down along the surface of the guide plate 14, and the oil liquid can be reliably guided to the receiving groove member 9. It is possible to prevent dripping or outflowing to the outside of the groove member 9. Therefore, when the guide plate 14 is employed, the guide plate 14 is also a member that constitutes a part of the delivery passage structure portion 7.

  As shown in FIG. 2A, the receiving groove member 9 is inclined so that one end side is lowered, and the outflow hole 10 is provided at the lowest position. A discharge pipe 16 is welded in communication with the outflow hole 10. A synthetic resin hose 17 is connected to the discharge pipe 16 so as to guide the oil liquid to the storage container 18.

  Next, a modified example of the delivery passage structure will be described.

  A modified example of the delivery passage structure portion 7 shown in FIG. 3A is a bolt 22 whose parts are composed of a head portion 20 and a shaft portion 21. An elongated passage space 23 into which the shaft portion 21 is inserted is formed in the bottom plate 11 of the passage member 8 having a U-shaped cross section. The bolt 22 is sent out in a so-called hanging state (neck hanging state) in which the head portion 20 is in the passage member 8 and the shaft portion 21 protrudes downward. The rest of the configuration is the same as that shown in FIG. 2 including parts not shown, and the same reference numerals are used for members having similar functions.

  The oil liquid in the passage member 8 drops or flows down from the passage space 23 and is collected in the receiving groove member 9 as in the case of FIG. Further, part of the oil liquid flows down along the surface of the shaft portion 21. The aforementioned oil drain passage 12 is a circular hole, but in this case, is formed by a passage space 23. In this case, the bottom plate 11 is arranged horizontally.

  A modification of the delivery passage structure portion 7 shown in FIG. 3B is a case where the shaft portion 21 is a long bolt 22, and the shaft portion 21 extends along the inclined surface of the guide plate 14. It is sent out while touching. Therefore, the passage member 8 has an inclined shape, and a passage space 23 similar to that in the above-described modified example functions as the oil discharge passage 12. Here, since the bolt 22 is inclined, the left side of the passage member 8 is in an open state. Other configurations are the same as those shown in FIG. 2 and FIG. 3 (A) including portions not shown, and members having similar functions are denoted by the same reference numerals.

  Further, in the case of the bolt 22, rust preventive oil or the like adhering to the shaft portion 21 is dropped directly on the receiving groove member 9 or flows down along the surface of the guide plate 14.

  Next, the outflow behavior of the oil liquid will be described.

  Rust prevention oil, lubricating oil, and the like applied to the surfaces of the nut 4 and the bolt 22 flow down from the surface of the component, become liquid, and accumulate at the bottom of the passage member 8. The oil liquid passes through the oil drainage passage 12 formed by a circular hole or a passage space of the shaft portion, and flows down along the surface of the guide member 14. As a result, the oil liquid is received by the receiving groove member 9, guided from the outflow hole 10 to a predetermined container such as the storage container 18, and is not spilled in the vicinity.

  The operational effects of the first embodiment described above are as follows.

  The delivery passage structure 7 includes a passage member 8 that delivers at least the parts 4 and 22 in a predetermined posture, a receiving groove member 9 that collects the oil flowing down from the passage member 8, and the receiving groove member 9. An oil liquid outflow hole 10 is provided. In the passage member 8, when the component is the projection nut 4 provided with the welding protrusion 5, the welding protrusion 5 is aligned in a predetermined vertical direction and is sent out in the form of a front and back. If the component is a bolt 22 with a head, the component is sent out in a suspended state with the head locked.

  The oil film such as rust preventive oil applied to the components 4 and 22 gradually flows down from the surface of the components and tends to be stored in a liquid state at the bottom and corner portions of the passage member 8. Thus, the oil liquid stagnated in the passage member 8 flows down from the passage member 8 and is collected in the receiving groove member 9. Further, when the oil adhering to the shaft portion 21 drips, the oil hangs down directly on the receiving groove member 9 or travels down the surface of the guide plate 14. Thereafter, the oil liquid is discharged from the outflow hole 10 provided in the receiving groove member 9 and stored in a predetermined storage container 18. Therefore, in the delivery passage structure portion 7, the passage member 8 that delivers the parts 4 and 22 in a predetermined posture, that is, the component delivery function, and the collection that collects the oil liquid flowing down from the passage member 8 by the groove member 9. The function and the discharge function of discharging the oil liquid from the outflow hole 10 of the receiving groove member 9 are fulfilled.

  As described above, the oil film applied to the parts 4 and 22 delivered from the vibrating bowl 1 becomes liquid and is collected in the receiving groove member 9 and discharged from the outflow hole 10. For this reason, the oil liquid does not fall on the base plate and related equipment in the vicinity of the parts feeder from the delivery passage structure 7 and can reliably prevent oil stains in the vicinity. By tilting the receiving groove member 9, the oil liquid can be collected in one place and stored in the storage container 18 or the like through the outflow hole 10. Therefore, the oil liquid is concentrated only at a predetermined location, which is effective in terms of factory cleaning management.

  Further, even if the oil film of the components 4 and 22 becomes liquid and stagnates on the component conveying plate 3, the oil liquid is continuously delivered from the component conveying plate 3 to the component conveying plate 3 by the oscillation of the vibration bowl 1. It is transferred to the passage member 8 of the structure portion 7. As described above, since the component conveying plate 3 is lowered on the outer wall plate 2 side, the oil liquid is transferred to the outer wall plate 2 side in a biased state. The oil liquid liquefied in the vibration bowl 1 is collected in an intensive manner in the delivery passage structure 7. That is, since it is collected in the delivery passage structure 7 which is the final position of the component transfer, all fluid oil in the vibrating bowl 1 is collected in the delivery passage structure 7 and is harmful. Leakage to the location can be prevented. In other words, since the rust preventive oil applied to the parts 4 and 22 is delivered from the delivery passage structure portion 7 in a state where only the minimum required oil film is formed, the dripping of the oil liquid outside the delivery passage structure portion 7 is performed. Can be avoided.

  An inclined guide plate 14 is disposed below the passage member 8, and the oil liquid flowing down from the oil discharge passage 12 flows down along the inclined surface of the guide plate 14. Accordingly, the oil liquid does not dripped onto the guide plate 14 and the oil droplets do not splash around the periphery, so that surrounding oil stains can be avoided.

  Since the receiving groove member 9 is inclined and arranged so that the oil liquid flows out from the lowest position, all the oil liquid can be discharged just by forming the outflow hole 10 in one place. Only one discharge pipe 16 is connected, which is effective for simplifying the structure.

  FIG. 4 shows a second embodiment of the present invention.

  In the first embodiment, the target part is a projection nut or a bolt, or the delivery passage structure portion 7, that is, the passage member 8 extends straight. However, in this second embodiment, the target part has a shaft portion and a head portion. Further, the entire delivery passage structure 7 is formed in an arc shape along a circular bowl. The guide plate 14 is provided with a component supporting function, and the way of forming the passage space 23 is different from that of the first embodiment.

  First, components will be described.

  The component to be delivered is a shaft-shaped component having a shaft portion and a head portion. Specifically, it is a bolt 22 and is composed of a head portion 20 and a shaft portion 21 in which a male screw is cut. And the shaft-shaped component in Example 2 is suitable when the length of the shaft portion is long. For example, the diameter of the head 20 is 18 mm, whereas the diameter and length of the shaft portion 21 are 13 mm and 150 mm, respectively.

  Next, the delivery passage structure will be described.

  The guide plate 14 is welded to the arc-shaped outer peripheral side end portion of the component conveying plate 3, whereby the component conveying plate 3 is in a positional relationship continuous to the guide plate 14. The guide plate 14 is configured by using a long and narrow steel plate material having a width dimension larger than the length of the shaft portion 21. The guide plate 14 is curved in a conical shape, and has a posture in which the conveying direction side of the component gradually rises. It is molded into. That is, the guide plate 14 is initially horizontal and has a large inclination angle and is smoothly continuous with the component conveying plate 3 without being squared, but gradually approaches the vertical direction toward the component moving direction. Thus, the inclination angle is small.

  The shaft-like component 22 is transferred in a posture lying along the longitudinal direction of the component conveying plate 3 by the vibration of the bowl as shown by a two-dot chain line in FIG. By the way, it is converted into a hanging posture. The part to be converted is the same posture control unit 13 as in the first embodiment.

  In order to achieve the hanging posture as described above, a passage space 23 is formed between the arc-shaped curved passage member 8 and the guide plate 14 that is continuous with the component conveying plate 3. The space width of the passage space 23 is indicated by a symbol C, and the shaft portion 21 can pass through, but the head portion 20 is locked. Various cross-sectional shapes of the passage member 8 can be employed, but here, the passage member 8 has an L-shaped cross section, and the arc-shaped member corresponding to the bottom plate 11 in the first embodiment is provided with a locking function. The arc-shaped member is also denoted by reference numeral 11.

  In other words, the space between the edge of the arc-shaped member 11 and the guide plate 14 is a passage space 23, and the shaft-like component 22 through which the shaft portion 21 passes has a lower surface of the head portion 20. The side surface of the head 20 is received on the surface of the guide plate 14 by the edge 11 a of the arc-shaped member 11. In other words, the lower surface of the head 20 is hooked by the edge portion 11 a and the lateral side surface of the head 20 is supported by the surface of the guide plate 14. In addition, the BB cross section of FIG. 4 (A) is the (B) figure of the same figure, and CC cross section is the (C) figure of the same figure, and it illustrates in the same way to FIG. 4 (F) below. Has been.

  In order to secure the passage space 23, the relative position between the end edge portion 11a of the passage member 8 and the guide plate 14 is accurately maintained. The lower end portion of the support member 25 formed of an elongated bar is bent, one end of the support member 25 is welded to the lower surface of the arc-shaped member 11, and the other end is welded to the guide plate 14. The support member 25 is welded to the guide plate 14 below the lower end of the shaft portion 21 in order to pass the shaft portion 21, and is bent as described above in order to secure a passage space. It is molded into an L shape.

  When the inclination angle of the guide plate 14 decreases and the shaft portion 21 approaches the vertical direction, the guide plate 14 changes so as to be suspended from the passage space 23 by the guide rail structure. This is shown in FIGS. 4A and 4F. The upper surfaces of the pair of parallel rail members 26, 27 serve as sliding surfaces, the lower surface of the head 20 slides there, and the shaft portion 21 passes through the passage space 23 between the rail members 26, 27. The passage width here is substantially the same as the space width C shown in FIG.

  One rail member 26 is disposed on the extension of the component conveying plate 3. For this purpose, as shown in FIG. 4 (F), welding is performed on the end portion of the component conveying plate 3. The other rail member 27 is welded to the end edge portion 11a. In order to reliably integrate the rail members 26 and 27, as shown in FIG. 4 (F), a U-shaped bar 28 provides a connection between the rail members and a passage space for the shaft portion 21. It is.

  Next, the receiving groove member will be described.

  As described in the first embodiment, the receiving groove member 9 has a lower outlet hole 10. In the second embodiment, a long and narrow plate material having a certain width is formed into a conical shape, and is deformed so that the conveyance direction side approaches a vertical standing posture. That is, the conical shape has a twisted shape on one side. Therefore, the lower edge of the guide plate 14 is in an inclined state in which the conveyance direction side is lowered.

  The receiving groove member 9 is welded to the lower edge of such a guide plate 14. The receiving groove member 9 here has a cross-sectional shape of a circular arc shape. In addition, a U-shaped cross section or a V-shaped cross section may be used. Other configurations are the same as those of the first embodiment including the portions not shown, and members having the same functions are denoted by the same reference numerals.

  Next, the conveying state of the shaft-like component will be described.

  When the shaft-like component 22 is moved counterclockwise with the posture lying on the component conveying plate 3 due to the vibration of the bowl, the tip of the shaft portion 21 enters the passage space 23 and the tip portion is guided by its own weight. It moves to the lower side of the plate 14, the head 20 is locked in the passage space 23, and the posture crosses the guide plate 14. When it is transferred by the vibration of the bowl, the inclination angle of the shaft portion 21 gradually decreases and approaches the vertical direction. Further, when conveyed by the vibration of the bowl, as shown in FIG. 4 (F), the shaft-like component 22 is completely suspended and is transferred to the next target location.

  At the time of the conveyance, rust preventive oil or the like adhering to the head portion 20 or the shaft portion 21 hangs down on the guide plate 14, flows down toward the receiving groove member 9, and is then discharged from the outflow hole 10.

  Although not shown, when the head 20 is first transferred on the component conveying plate 3, the head 20 advances without passing through the passage space 23, and the tip of the shaft portion 21. When the portion moves from the component conveying plate 3 to the passage space 23, the tip of the shaft portion 21 passes through the passage space 23, and the entire shaft-like component 22 swings counterclockwise around the head 20 and is suspended. It goes down.

  The operational effects of the second embodiment described above are as follows.

  When the bolt 22 that has been transferred to the component conveying plate 3 by the vibration of the bowl reaches the passage space 23 that is continuous with the component conveying plate 3, that is, at the stage where the bolt 22 begins to reach the delivery passage structure portion 7, The shaft portion 21 passes through the passage space 23, and the tip of the shaft portion is lowered toward the lower side by the weight of the shaft portion 21. On the other hand, the head 20 cannot pass through the passage space 23 and is in a suspended state (neck hanging state). Thus, in the initial stage of reaching the passage space 23, the inclination angle of the guide plate 14 is large and the shaft portion 21 has a large inclination angle close to the horizontal direction. At this time, when the oil liquid adhering to the bolts 22 hangs down on the guide plate 14, the oil liquid flows down on the guide plate 14 and flows into the receiving groove member 9, and further from the outflow hole 10 to a predetermined location. Discharged.

  Furthermore, when the shaft-like component 22 in a suspended state is transferred by the vibration of the bowl, the shaft portion 21 gradually changes to an inclination angle approaching the vertical direction. Even at this stage, the oil is discharged in the same manner as described above.

  Further, when the shaft-like component 22 in the suspended state is transferred by the vibration of the bowl, the shaft portion 21 assumes a substantially vertical hanging posture and is sent out in this posture. Even at this stage, the oil is discharged in the same manner as described above. That is, the oil liquid is collected and discharged until the shaft-shaped part 22 is separated from the delivery passage structure 7.

  Accordingly, a passage space 23 for allowing the shaft portion 21 to pass between the passage member 8 and the guide plate 14 continuing to the component conveying plate 3 and for locking the head portion 20 continues to the component conveying plate 3. Since the shaft portion 21 of the shaft-shaped component 22 that has moved the component conveying plate 3 smoothly enters the passage space 23 and is surely suspended, the shaft-shaped component is correctly transferred. Carried out in

  At the same time that the conveying posture of the shaft-like component 22 is changed in the vertical direction, the oil liquid is reliably collected and discharged. Since the shaft portion 21 of the suspended shaft-like component 22 is guided by the guide plate 14 whose inclination angle gradually changes, the posture change of the shaft-like component 22 and the processing of the oil liquid can be achieved at the same time, and the functionality is improved. Excellent parts feeder is available. Since the receiving groove member 9 is provided at the lower edge of the guide plate 14, the oil liquid can be reliably captured and the oil contamination in the vicinity can be completely prevented.

  As the transport movement of the shaft-shaped component 22 proceeds, the direction of the guide plate 14 and the shaft portion 21 approaches the vertical direction, so that the oil liquid adhering to the surfaces of the shaft portion 21 and the guide plate 14 flows down. Is made even more aggressive, and more oil is captured by the receiving groove member 9.

  At the initial stage when the shaft-like component 22 reaches the passage space 23, the inclination angle of the guide plate 14 is large and the shaft portion 21 has a large inclination angle close to the horizontal direction. It is possible to smoothly shift from 3 to the guide plate 14. Since the shaft-shaped part 22 is long, it is difficult to change the direction suddenly. However, since the inclination angle of the guide plate 14 is increased in the initial stage, the turning angle of the shaft-shaped part 22 is large. This makes it possible to reduce the size and make a smooth turning, ensuring reliable and reliable component behavior.

  The guide plate 14 is formed by forming a plate material having a constant width into a conical shape, and further reducing the inclination angle by further twisting one side. Accordingly, the shaft-like component 22 that has moved in the posture of lying on the component conveying plate 3 of the vibration bowl is gradually changed in the posture in the standing direction and separated from the guide plate 14, that is, from the delivery passage structure portion 7. In the part which leaves | separates, it becomes possible to set it as a completely suspended state. Such a posture change of the component is suitable in the case of a long special bolt.

  As described above, according to the parts feeder of the present invention, in the delivery passage structure that guides the parts to the outside of the vibrating bowl, the oil liquid such as rust preventive oil is collected and guided to a predetermined location, so that the parts Oil liquid does not adhere to the mechanism part of the feeder and the support base of the parts feeder is not soiled. Therefore, it can be used in a wide range of industrial fields such as an assembly process of an automobile part in which a parts feeder is installed.
