Description

  The present invention relates to a linear feeder that conveys parts straightly. More specifically, the present invention relates to a linear feeder that conveys a rod-shaped component while suspending the component when the component is a rod-shaped component.

  Conventionally, it is known to use a bowl-type vibrating parts feeder as a part alignment and supply system. In this bowl-type vibrating parts feeder, a plurality of parts are put into a bowl that constitutes a movable part, and a plurality of parts thrown into the bowl are aligned by a bowl that vibrates in the circumferential direction. It is comprised so that it may convey and supply to.

  And when the supply path of components is long, it is known that a linear feeder is used to convey components aligned by a bowl-type vibrating parts feeder, for example, straight in the horizontal direction (see, for example, Patent Document 1). ).

JP 2000-344335 A

  However, when the part is a long and narrow bar-shaped part, if the bar-shaped part is transported in the longitudinal direction, even if the bar-shaped part continues in the longitudinal direction, the conveyance density in the linear feeder is increased to the length of the bar-shaped part or less. It causes a problem that cannot be done.

  Further, if the rod-shaped component to be conveyed has a non-circular cross section, the circumferential position in the cross-section of the rod-shaped component also needs to be aligned. However, if the rod-shaped component is conveyed in the longitudinal direction, There is also a problem that alignment in the direction becomes difficult.

  The objective of this invention is providing the linear feeder which can raise the conveyance density of a rod-shaped component.

  Another object of the present invention is to provide a linear feeder that can convey a rod-shaped component while aligning its position in the circumferential direction of the cross section without stagnation.

  The present invention provides a linear feeder having a linear vibration base that vibrates by means of vibration, and a conveying member that is provided on the linear vibration base and vibrates together with the linear vibration base and conveys a rod-shaped part that is mounted in the longitudinal direction. It is an improvement.

  The characteristic configuration is that the conveying member is erected on both sides of the linear vibration base in the width direction, and the support member is provided so as to extend in the longitudinal direction of the linear vibration base and suspends a rod-shaped component. A pair of suspension members, and a pair of regulating rails that are provided on the support member so as to extend in the longitudinal direction of the linear vibration base and sandwich the rod-like component suspended on the pair of suspension members from the width direction of the linear vibration base. It is in place.

  In this linear feeder, the inclined surfaces that increase the distance between them toward the upstream side can be formed on either one or both of the upstream facing surfaces of the pair of regulation rails, in which case the inclined surface is in the transport direction. Preferably, they are formed on the opposing surfaces on the upstream side of the pair of regulation rails. Then, it is preferable that either one or both of the pair of regulation rails are attached to the support member so as to be movable via an elastic body.

  Since the linear feeder of the present invention includes a pair of suspension members for suspending the rod-shaped component, the rod-shaped component is suspended from the suspension member and conveyed in the diameter or width direction. In general, the diameter or width of the rod-shaped component is shorter than the length thereof, so that the linear feeder of the present invention that conveys the rod-shaped component while suspending the rod-shaped component is compared with the case of conveying the rod-shaped component continuously in the longitudinal direction. The bar-shaped parts can be transported at intervals equal to or less than the length of the bar-shaped parts, and the transport density can be increased.

  In addition, the linear feeder according to the present invention includes a pair of regulating rails that sandwich the suspended rod-shaped part from the width direction of the linear vibration base, in addition to the pair of suspension members that suspend the rod-shaped part. The cross-section non-circular part of the bar-shaped part to be conveyed is moved between the regulating rails, and the dimension in the width direction in the conveyance direction of the cross-section non-circular part is minimized, so that the circumferential position in the cross-section of the bar-shaped part Can be aligned.

  Here, if a restriction rail is provided separately from the suspension member for suspending the rod-shaped part, it is conceivable that the rod-shaped part conveyed in the horizontal direction in the suspended state will be caught at the entrance of the restriction rail. If an inclined surface that enlarges the distance toward each other is formed on the upstream side of the pair of regulating rails, the non-circular cross section is brought into contact with the inclined surface and the non-circular cross section enters between the pair of regulating rails. It can be made easy. In that case, if the inclined surfaces are shifted in the transport direction, it is possible to avoid a situation in which the non-circular cross-section is sandwiched between the inclined surfaces.

  If the regulation rail is movably attached to the support member via the elastic body, for example, even if the non-circular cross section is sandwiched between the pair of regulation rails, the distance between the pair of regulation rails is By changing, rotation about the vertical axis | shaft of the suspended rod-shaped components can be promoted. As a result, by not rotating, it is possible to avoid a state in which the rod-like component is caught at the entrance of the regulation rail.

  Therefore, in the linear feeder of the present invention, it is possible to convey the rod-shaped parts while aligning the positions in the circumferential direction of the cross section without stagnation.

  Next, embodiments for carrying out the present invention will be described in detail with reference to the drawings.

  6 and 7 show a linear feeder 10 according to the present invention. The linear feeder 10 in the figure is shown as conveying the parts 14 aligned by the bowl-type vibrating part feeder 9 straight in the horizontal direction.

  Here, the bowl-type vibrating part feeder 9 shown in the figure has a bowl 9a that constitutes a movable part, and a plurality of parts 14 put into the bowl 9a are aligned by the movable part that vibrates in the circumferential direction. It is comprised so that it may convey in a direction.

  The part in this embodiment is an elongated bar-shaped part 14, and as shown in FIGS. 4 and 5, the bar-shaped part 14 has a large-diameter portion 14a having a large cross-sectional area and a small-diameter having a smaller cross-sectional area than the large-diameter portion 14a. It shall have the part 14b. The large-diameter portion 14a and the small-diameter portion 14b are each formed in a cylindrical shape and are continuously provided coaxially, and a screw portion 14c having a non-circular cross-section is further formed at the end of the small-diameter portion 14b.

  As shown in FIG. 5, the screw portion 14c is formed such that both sides in the width direction are cut and the thickness t is smaller than the outer diameter d of the screw portion 14c, and the cross section thereof is non-circular. . In addition, a flange 14d made of ridges extending continuously in the circumferential direction is formed on the outer periphery of the large-diameter portion 14a having a circular cross section.

  Further, as shown in FIG. 4, the length of the large diameter portion 14a is shorter than the length of the small diameter portion 14b, and the bar G is formed so that the center of gravity G exists in the small diameter portion 14b. Then, as shown in FIG. 7, the bowl-type vibrating part feeder 9 aligns the rod-shaped parts 14 and conveys them in the longitudinal direction.

  The linear feeder 10 according to the present invention is configured to further convey the rod-shaped parts 14 aligned by the bowl-type vibrating parts feeder 9 and conveyed in the longitudinal direction further straight in the horizontal direction. As shown in FIG. A base 12 is provided at the place 8 and the vibration means 11 is provided on the top, and a linear vibration base 13 that reciprocally vibrates in the longitudinal direction by the vibration means 11.

  The base 12 and the vibration means 11 are the same as those used in the conventional linear feeder 10, and the base 12 is placed on the installation place 8. Examples of the vibration means 11 include an electromagnet and a piezoelectric element. However, even if this vibration means 11 is what is called a mechanical type which vibrates the linear vibration base 13 by electrically driving mechanical mechanisms, such as a cam and a link, the linear vibration base 13 is utilized using air. A so-called pneumatic type may be used.

  The linear vibration base 13 is provided with a conveying member 15 that conveys the rod-shaped component 14 that is vibrated and mounted with the linear vibration base 13. And the conveyance member 15 in the linear feeder 10 of this invention shall be provided with the supporting member 16, the suspending member 17, and the control rails 18 and 19. FIG.

  The support members 16 are erected on both sides in the width direction of the linear vibration base 13 (FIGS. 1 to 3). The support member 16 in this embodiment is a columnar member having a square cross section, and the support member 16 made of this columnar member is disposed on both sides in the width direction of the linear vibration base 13 and in the longitudinal direction of the linear vibration base 13. FIG. 6 shows a case where a plurality of pairs are set up at predetermined intervals, and FIG.

  The pair of support members 16 provided on both sides in the width direction of the linear vibration base 13 are erected with an interval through which the large-diameter portion 14a of the rod-like component 14 which is a component can pass with a margin. (FIG. 1).

  A pair of suspension members 17 are provided at the upper ends of the plurality of pairs of support members 16 so as to extend in the longitudinal direction of the linear vibration base 13. As shown in FIG. 1, the pair of suspending members 17 has a gap S1 through which the small-diameter portion 14b of the rod-like component 14 which is a component can pass and the large-diameter portion 14a cannot pass, and the support member 16 It shall be attached to the upper end of

  As shown in FIGS. 6 and 7, the rod-like component 14 conveyed in the longitudinal direction by the bowl-type vibrating part feeder 9 is linearly guided so as to be guided between a pair of suspension members 17 in a state of extending in the horizontal direction. The feeder 10 is connected to a bowl-type vibrating part feeder 9.

  For this reason, as shown in FIG. 4, the rod-shaped component 14 guided in a horizontal state between the pair of suspension members 17 in the linear feeder 10 has a small diameter portion 14 b passing between the pair of suspension members 17. However, the large-diameter portion 14a cannot pass between the pair of suspension members 17, and the large-diameter portion 14a is supported by the pair of suspension members 17 as shown in FIG. Is configured to be transportable in the longitudinal direction of the pair of suspending members 17 while being suspended from the pair of suspending members 17.

  As shown in FIG. 5, the pair of suspending members 17 suspends the rod-shaped component 14 on the upstream side thereof, and on the downstream side conveyed thereafter, the concave groove 17 a into which the flange 14 d of the rod-shaped component 14 can enter. Are continuously formed in the longitudinal direction which is the conveying direction.

  As shown in FIGS. 1 to 5, the linear feeder 10 of the present invention includes a pair of regulating rails 18 and 19. That is, a pair of regulation rails 18 and 19 are provided extending in the longitudinal direction, which is the horizontal direction, in the middle of the plurality of pairs of support members 16 in the vertical direction. The pair of regulation rails 18 and 19 are perpendicular to the width direction of the linear vibration base 13, i.e., the conveying direction, with respect to the threaded portion 14 c which is a non-circular cross section of the rod-like component 14 suspended from the pair of suspension members 17. When the external shape in the width direction of the linear vibration base 13 of the screw portion 14c is the smallest, the screw portion 14c can enter and pass between the pair of regulation rails 18 and 19. Provided.

  Specifically, the gap between the minimum value in the cross-sectional outer shape of the screw portion 14c that is a non-circular cross-section, that is, a gap S2 that is wider than the thickness t and narrower than the outer diameter d of the screw portion 14c, 19 is provided in the middle of the support member 16 in the vertical direction.

  As shown in FIGS. 1 to 3, one regulation rail 18 is fixed to one of a plurality of pairs of support members 16, and the other regulation rail 19 is placed on the other of the plurality of pairs of support members 16 via an elastic body 21. It is mounted movably.

  Specifically, each of the pair of regulation rails 18 and 19 is a bar having a square cross section, and a male screw 22 for mounting on one side thereof is predetermined in the longitudinal direction in accordance with the interval between the plurality of pairs of support members 16. A plurality are provided with an interval of. The support member 16 corresponding to the male screw 22 is formed with a hole 16a through which the male screw 22 can be inserted.

  Each male screw 22 of one of the regulation rails 18 is inserted into each hole 16a of a plurality of support members 16 that are erected at a predetermined interval in the longitudinal direction on one side of the linear vibration base 13. By tightening the nut 23 from both sides so as to sandwich the support member 16, the one regulation rail 18 is fixed to the support member 16 on one side.

  A coil spring 21 having a relatively soft elastic coefficient is fitted into each male screw 22 of the other regulation rail 19. In this state, the respective male screws 22 of the other regulation rail 19 are respectively provided in the respective holes 16a of the plurality of support members 16 erected on the other side of the linear vibration base 13 at a predetermined interval in the longitudinal direction. Is inserted. A pair of nuts 23 are screwed onto the male screw 22 that has passed through the support member 16. As a result, the other regulation rail 19 is movably attached to the support member 16 on the other side via the coil spring 21 that is an elastic body.

  Here, when the nut 23 first screwed into the male screw 22 that has passed through the support member 16 is brought into contact with the support member 16 and further screwed into the first nut 23 thereafter, the nut 23 is supported by the other regulation rail 19. The coil spring 21 sandwiched between the members 16 is gradually contracted, the other restriction rail 19 is gradually moved away from the one restriction rail 18, and the gap S2 between the pair of restriction rails 18 and 19 is enlarged. become.

  For this reason, the gap S2 between the pair of regulation rails 18 and 19 is slightly wider than the minimum value in the cross-sectional outer shape of the non-circular cross section of the rod-like component 14, that is, the gap S2 is the thickness of the screw portion 14c. At a stage where it is wider than t and smaller than the outer diameter d of the screw portion 14c, the screwing of the first nut 23 is stopped, and then the screwed nut 23 is fastened so as to contact the first nut 23. The pair of nuts 23 is prevented from subsequently loosening.

  In this way, the pair of regulating rails 18 and 19 are spaced apart by a gap slightly wider than the minimum value in the cross-sectional outline of the threaded portion 14c of the rod-shaped component 14, that is, the non-circular cross-section, and the vertical direction of the support member 16 It is provided in the middle.

  The pair of regulation rails 18 and 19 are provided on the downstream side of the pair of suspension members 17 that convey the rod-shaped component 14 while suspending it. That is, as shown in FIGS. 4 and 5, the pair of regulation rails 18 and 19 are disposed upstream of the pair of suspension members 17 on which the rod-like parts 14 supplied from the bowl-type vibrating part feeder 9 are first mounted. , Not provided.

  For this reason, the rod-like component 14 suspended on the upstream side of the pair of suspension members 17 has a threaded portion 14c which is a non-circular cross-sectional portion at the lower end of the small-diameter portion 14b in the middle of being conveyed toward the downstream side. , It will enter between the pair of regulating rails 18 and 19.

  As shown in FIGS. 2 and 3, an upstream facing surface of the pair of restriction rails 18 and 19 so that the screw part 14 c having a non-circular cross section can easily enter between the pair of restriction rails 18 and 19. In this case, inclined surfaces 18a and 19a are formed on both sides to increase the distance between them toward the upstream side. And the inclined surfaces 18a and 19a in a figure show the case where it shifted and formed along the conveyance direction.

  Next, the operation of the linear feeder configured as described above will be described.

  First, the linear feeder 10 is installed so as to be continuous with the bowl-type vibrating part feeder 9. Specifically, as shown in FIGS. 6 and 7, the upstream end portions of the pair of suspending members 17 of the linear feeder 10 are opposed to the component outlet 9 b of the bowl-type vibrating part feeder 9, and in this state, The base 12 is fixed to the installation place 8.

  Then, the rod-shaped part 14 to be aligned and conveyed is put into the bowl 9a in the bowl-type vibrating part feeder 9, and the bowl-type vibrating part feeder 9 is operated to vibrate the bowl 9a in the circumferential direction. The plurality of rod-shaped components 14 put in the bowl 9a are conveyed in the circumferential direction while being aligned.

  In the linear feeder 10 of the present invention, the bowl-type vibrating part feeder 9 is operated, and at the same time, the linear vibrating base 13 is vibrated by the vibrating means 11. Due to the vibration of the linear vibration base 13, the parts 14 aligned by the bowl-shaped vibration part feeder 9 and mounted on the pair of suspending members 17 in the linear feeder 10 are conveyed straight from the carry-out port 9 b in the horizontal direction.

  Here, in the linear feeder 10 of the present invention, as shown in FIG. 5, the pair of suspending members 17 allows the small-diameter portion 14b of the rod-like component 14 to pass therethrough and the large-diameter portion 14a cannot pass therethrough. It is attached to the upper end of the support member 16 with S1 open. For this reason, as shown in FIG. 4, the rod-shaped component 14 guided in a horizontal state between the pair of hanging members 17 in the linear feeder 10 has a small diameter portion 14 b where the center of gravity G is present of the pair of hanging members 17. The large-diameter portion 14a cannot pass between the pair of suspending members 17, but the large-diameter portion 14a is supported by the pair of suspending members 17, and the rod-shaped component 14 is It is suspended upstream of the suspension member 17.

  Further, in FIG. 4, the rod-shaped component 14 is guided from the large diameter portion 14 a side on the pair of hanging members 17 in the linear feeder 10, and all of the small diameter portions 14 b are guided between the pair of hanging members 17. In the stage, the case where the small diameter portion 14b is suspended by passing between the pair of suspension members 17 is shown.

  However, although not shown, when the rod-shaped component 14 is guided from the small diameter portion 14 b side between the pair of hanging members 17 in the linear feeder 10, the small diameter portion 14 b passes between the pair of hanging members 17. It will pass immediately and be suspended.

  Thus, in the linear feeder 10, the rod-like component 14 is conveyed in the longitudinal direction of the pair of suspension members 17 in a state of being suspended from the pair of suspension members 17.

  On the other hand, since the pair of regulating rails 18 and 19 are not provided on the upstream side of the pair of suspension members 17, the rod-like component 14 suspended on the upstream side of the pair of suspension members 17 is directed toward the downstream side. In the middle of being conveyed, the threaded portion 14 c, which is a non-circular section in the rod-shaped component 14, enters between the pair of regulation rails 18 and 19.

  Here, since the pair of regulating rails 18 and 19 are provided with a gap S2 slightly wider than the minimum value t in the cross-sectional outer shape of the non-circular cross section, the pair of restricting rails 18 and 19 are hung on the upstream side of the pair of suspending members 17. As shown in FIG. 3A, the rod-shaped component 14 that is provided and is directed to the downstream side has a threaded portion 14c when the width of the threaded portion 14c that is a non-circular cross-section is perpendicular to the conveying direction. Enters between the pair of regulating rails 18 and 19, and the rod-shaped component 14, which is a component, is conveyed to the downstream side in a state of being suspended by the pair of suspension members 17.

  As shown in FIG. 1, in this embodiment, since the concave groove 17a in which the flange 14d in the rod-shaped component 14 can enter is formed in the pair of suspending members 17, the rod-shaped part with the flange 14d entering the concave groove 17a. The part 14 is conveyed. For this reason, the excessive rocking | fluctuation in the middle of conveyance of the rod-shaped component 14 suspended by a pair of suspension member 17 is prohibited.

  And since the large diameter part 14a and the small diameter part 14b which comprise the columnar shape continue coaxially, the rod-shaped component 14 can rotate centering | focusing on a vertical axis | shaft in the suspended state. For this reason, when the width of the threaded portion 14c of the rod-shaped component 14 that is rotated about the vertical axis is not the minimum, the threaded portion 14c, which is a non-circular cross-section, has a pair of regulating rails 18, No entry during 19. Therefore, if the screw part 14c does not enter between the pair of regulating rails 18 and 19, the subsequent conveyance of the suspended rod-like part 14 becomes difficult.

  However, in the linear feeder 10 of the present invention, the inclined surfaces 18a and 19a that increase the distance from each other toward the upstream side are formed on the upstream facing surfaces of the pair of regulating rails 18 and 19, and therefore in the conveying direction. When the orthogonal width is not the minimum, as shown in FIGS. 3B and 3C, the threaded portion 14c, which is a non-circular cross-sectional portion of the rod-shaped component 14 directed toward the downstream side, contacts the inclined surfaces 18a and 19a.

  And while moving to the downstream side and moving while the threaded portion 14c is in contact with the inclined surfaces 18a, 19a, the rod-like component 14 is rotated as shown by the solid line arrow around the vertical axis, The threaded portion 14c, which is a non-circular cross section, enters between the pair of regulating rails 18 and 19 when the width perpendicular to the conveying direction is minimized.

  In particular, in this embodiment, since the inclined surfaces 18a and 19a of the pair of regulation rails 18 and 19 are shifted along the transport direction, the width perpendicular to the transport direction of the non-circular section is not minimum. When the suspended bar-shaped part 14 moves downstream, the threaded part 14c having a non-circular cross section comes into contact with the inclined surfaces 18a, 19a one side from the width direction in the transport direction, and the suspended bar-shaped part 14 is suspended. Rotation around the vertical axis can be promoted.

  That is, since the inclined surfaces 18a and 19a are shifted, the inclined surfaces 18a and 19a simultaneously come into contact with the non-circular section from both sides, and the threaded portion 14c which is the non-circular section is sandwiched between them and suspended. It is possible to avoid a situation in which the rotation of the rod-shaped part 14 around the vertical axis is hindered.

  On the other hand, even if the inclined surfaces 18a and 19a are shifted, both of the inclined surfaces 18a and 19a or one of the regulation rails 18 and the downstream inclined surface 19a are formed on the screw portion 14c having a non-circular cross section from both sides in the width direction. It is conceivable that the screw portion 14c is sandwiched between them as shown in FIG.

  However, in the linear feeder 10 of the present invention, one regulation rail 18 is fixed to one support member 16, and the other regulation rail 19 is movable to the other support member 16 via a coil spring 21 that is an elastic body. Installed. For this reason, if the threaded portion 14c, which is a non-circular cross-sectional portion of the rod-like component 14 heading downstream, is sandwiched between one regulating rail 18 and the inclined surface 19a on the downstream side, the other regulation along with the vibration of the support member 16 is assumed. The rail 19 moves as indicated by a solid arrow, and the gap between the pair of regulation rails 18 and 19 is increased or decreased.

  As a result, a repeated load is applied from the other restricting rail 19 to the threaded portion 14c, which is a non-circular cross section between the one restricting rail 18 and the downstream inclined surface 19a, and the one restricting rail fixed to the support member 16 is applied. Rotation of the suspended rod-like part 14 is promoted with 18 as a fulcrum.

  As a result, the inclined surfaces 18a, 19a of the pair of regulating rails 18, 19 or the one regulating rail 18 and the downstream inclined surface 19a are suspended by sandwiching the screw portion 14c having a non-circular cross section from both sides. A situation where the rotation of the rod-shaped part 14 around the vertical axis is prohibited is avoided.

  Then, when rotation about the vertical axis of the suspended rod-like component 14 is performed as indicated by the solid line arrow, the width perpendicular to the conveying direction of the screw portion 14c, which is a non-circular cross section, is minimized. At this stage, the rod enters between the pair of regulation rails 18 and 19, and the position in the circumferential direction of the cross section with respect to the conveying direction of the rod-shaped component 14 is made constant.

  For this reason, in the linear feeder 10 of the present invention, it is possible to convey the rod-shaped parts 14 to be conveyed with the cross-sectional circumferential direction being surely aligned. And in this linear feeder 10, since it conveys in the state which suspended the rod-shaped component 14, compared with the case where the rod-shaped component 14 is conveyed in a longitudinal direction, a conveyance density can be raised.

  In the above-described embodiment, a case where a plurality of support members 16 each having a columnar member having a square cross section are erected at predetermined intervals in the longitudinal direction of the linear vibration base 13 has been described. As long as the member 17 and the regulation rails 18 and 19 can be provided, the support member may be a columnar member having a cross section other than a square or a plate member. And when it is a board | plate material, you may make it extend in a longitudinal direction on the both sides of the linear vibration base 13, and do not need to make multiple standing, but to make it provide a pair.

 In the above-described embodiment, the linear feeder 10 connected to the bowl-type vibrating part feeder 9 has been described. However, the linear feeder 10 of the present invention does not necessarily need to be connected to the bowl-type vibrating part feeder 9.

 In the above-described embodiment, the case where the inclined surfaces 18a and 19a are formed on both upstream facing surfaces of the pair of regulating rails 18 and 19 has been described. However, the inclined surfaces 18a and 19a are a pair of regulating rails 18. , 19 may be one of the upstream facing surfaces, and when the cross-sectional non-circular portion 14c of the rod-shaped part 14 can enter between the regulating rails 18, 19, such inclined surfaces 18a, 19a are provided. It does not have to be formed.

 In the above-described embodiment, the large-diameter portion 14a and the small-diameter portion 14b having a columnar shape are described using the rod-shaped component 14 that is coaxially continuous. However, as long as the pair of suspending members 17 can be hung, The component 14 is not limited to such a shape.

 Further, in the above-described embodiment, the screw part 14c whose both sides are cut constitutes a non-circular cross section, but the cross section can be used as long as the position in the circumferential direction of the cross section can be determined by sandwiching the pair of regulation rails 18 and 19. The non-circular portion is not limited to such a shape.

 Further, in the above-described embodiment, the case where one of the pair of regulation rails 18 is fixed to the support member 16 and the other 19 of the pair of regulation rails is attached to the support member 16 via the elastic body 21 is described. . However, both the pair of regulation rails 18 and 19 may be movably attached to the support member 16 via the elastic body 21 as long as the rotation of the suspended rod-shaped part 14 around the vertical axis can be promoted. good.
