Description

  The present invention relates to a parts feeder for sending parts to a predetermined part supply location in a production line.

  2. Description of the Related Art Conventionally, there is known a parts feeder that rotates a rotating drum that accommodates components therein and discharges the components one by one from the rotating drum (for example, see Patent Document 1).

  Here, some of the components have a posture suitable for the work, for example, when the worker takes out the work from the parts supply place. Such parts are preferably sent out in a posture suitable for work by a parts feeder.

  In order to meet such a demand, a parts feeder is conceivable in which the following filter is attached to the rotating drum and parts are sent through the filter. That is, a parts feeder including a cylindrical filter provided with a linear passage having a cross-sectional shape corresponding to a contour shape in a plan view when a component in a desired posture is viewed in the delivery direction can be considered. According to such a parts feeder, when a part whose posture is constantly changing inside the rotating drum is in a posture capable of passing through the filter, it is discharged from the rotating drum through the filter. . As a result, the parts are sent out to the parts supply place in such a manner that they can pass through.

Japanese Patent Laid-Open No. 7-137829

  Here, depending on the shape of the part, in the above-described cylindrical filter, the part may not necessarily have a desired posture, and it is required to send the part in a desired posture with high accuracy.

  Accordingly, it is an object of the present invention to provide a parts feeder that can pay attention to the problems as described above and can send out parts in a desired posture with high accuracy.

  In order to solve the above problems, a parts feeder according to the present invention rotates around a central axis of a storage space defined by a cylindrical peripheral wall, and is attached to the peripheral wall and a rotating drum for storing components in the storage space. , Having a part discharge path that extends in a tangential direction of the peripheral wall in a cross-sectional shape according to a contour shape in a plan view from the predetermined direction and opens outside the rotary drum, and can pass through the part discharge path A filter that discharges the component in a correct posture through the component discharge path as the rotary drum rotates, and guides the component discharged from the filter to a component supply location while maintaining the posture at the time of discharge. A guide rail, and the filter opens to the inside of the housing space to take in the part, and the part discharge path extends to the inside of the rotating drum. By following the al displacement path leads to the component discharge path, and characterized by having a component taking unit for the components of the possible orientation passing through the path leading to the component discharge path.

  In the parts feeder of the present invention, the filter has a part discharge path having a cross-sectional shape corresponding to the contour shape in plan view from a predetermined direction of the part, and discharges through the part in a posture capable of passing through the part discharge path. It has become. In other words, the operation of designing the cross-sectional shape of the component discharge path to a shape corresponding to the contour shape when the component is in a desired posture allows the component to be sent out in the desired posture.

  Here, depending on the shape of the component, the component may not be in a desirable posture only by the component discharge path. As an example of such a component, for example, a component having different shapes between the left and right ends in a plan view from a certain direction, and a posture in which one end side is preferably in front of the feed, etc. Can be mentioned. Alternatively, there may be mentioned a part or the like in which the contour shape is substantially the same even if the component is laid down by 90 ° around the center of the contour shape corresponding to the desired posture. In addition to the desired posture, these parts can be passed through the filter's part discharge path even in the opposite or sideways posture, and it is possible to send the parts in the desired posture with high accuracy. It is difficult only by the road.

  On the other hand, in the parts feeder of the present invention, the filter has a posture in a posture that allows the filter to follow the path shifted from the extension line to the inside of the rotating drum of the parts discharge path to the parts discharge path and pass through the path. A component take-in portion that leads to the component discharge path is provided. As a result, the condition that the part take-in part can pass to the part discharge path is added to the condition that the part discharge path can pass, and the part shape that can pass can be defined in three dimensions. As a result, the accuracy of sending parts in a desired posture by the filter is increased. Thus, according to the parts feeder of the present invention, parts can be sent out in a desired posture with high accuracy.

  In the parts feeder according to the present invention described above, the component has a shape different between the left and right ends in a plan view from the direction orthogonal to the predetermined direction. However, it is preferable to guide the component having the predetermined end of the left and right ends toward the component discharge path to the component discharge path.

  In this preferred parts feeder, in the above-described part taking-in part, a part having a predetermined one end directed to the part discharge path can be passed through the part discharge path. As a result, even if it is difficult to send out the desired posture with high accuracy only with the component discharge path, such as the posture in which the one end side is in front of the delivery, it is possible to send out the desired posture with high accuracy.

  In the parts feeder according to the present invention, the component take-in unit may include an inclination suppression unit that guides the component to the component discharge path while suppressing an inclination around the center of the contour shape in plan view in the predetermined direction. It is also suitable that is provided.

  In this preferred parts feeder, the component is guided to the component discharge path in a state in which the inclination around the center of the contour shape is suppressed by the component taking-in portion. As a result, even if it is difficult to send out with a desired posture with high accuracy only with the component discharge path, such as having substantially the same contour shape even if it is laid down, it can be sent out with a desired posture with high accuracy.

  Further, in the parts feeder according to the present invention, the part take-in part guides the part from the opening opened toward the central axis to the part discharge path along a curved path or a skew path. Also good.

  According to this parts feeder, parts can pass through a curved path or a skew path in a desired posture and follow these paths to the parts discharge path without interfering with the peripheral part. Thus, the peripheral part and the part can be configured to interfere with each other. These paths are paths that bend or obliquely follow the component discharge path from the opening opened toward the central axis. As a result, the length of the component take-in portion, that is, the length of the filter in the tangential direction of the peripheral wall of the rotating drum, is shortened compared to the case where the route to the component discharge path is a path extending substantially straight, for example. can do. This also leads to shortening of the portion of the guide rail that serves as a receiving port for the parts discharged from the filter, so that the material cost can be reduced.

  Further, in the parts feeder according to the present invention, the component take-in portion is shifted from the extension line in the radial direction of the rotary drum from the opening opened in the circumferential direction of the peripheral wall to the component discharge passage. The part may be guided by following the above.

  According to this parts feeder, the part can pass without interfering with the peripheral part in a desired posture at the step part between the part taking-in part and the part discharge path, but the peripheral part and the part interfere in other postures. It can be constituted as follows. This makes it possible to distinguish between passability / impossibility of passing between a desired posture and other postures even for parts that are difficult to realize a curved path or a skew path that can be passed in a preferred posture due to its shape. Can be provided.

  Further, in the parts feeder according to the present invention, provided at the component supply location, provided at a midway position of the guide rail, and an extraction detection sensor for detecting the removal of the component from the component supply location, and discharged from the filter. And a stopper for feeding the part to the part supply location according to the detection result of the take-out detection sensor, while holding the part moving on the guide rail in the middle position. Is preferred.

  According to this preferred parts feeder, since the parts are replenished in accordance with the removal from the parts supply place, it is possible to efficiently supply the parts according to the usage pace of the parts.

  According to the parts feeder of the present invention, parts can be sent out in a desired posture with high accuracy.

  Hereinafter, an embodiment of the parts feeder of the present invention will be described. First, the first embodiment will be described.

  FIG. 1 is an external perspective view showing a parts feeder according to a first embodiment of the present invention. FIG. 2 is a view showing the peripheral structure of the rotating drum in the parts feeder shown in FIG. 1 as seen in the direction of arrow V11 in FIG.

  The parts feeder 1 shown in FIGS. 1 and 2 is a device that sends out a part P1 to a predetermined part supply location 1a in a production line. The parts feeder 1 includes a rotating drum 11, a filter 12, a guide rail 13, a component supply tray 14, a drum driving unit 15, and a plurality of support poles 16.

  The rotary drum 11 includes a cylindrical peripheral wall 111, a circular bottom wall 112, and a circular lid wall 113, and a plurality of components P1 are accommodated in an accommodation space 114 defined by these walls. The rotary drum 11 is rotationally driven in the direction of arrow D11 in the drawing around the central axis 114a of the accommodation space 114 by the drum drive unit 15 connected to the bottom wall 112. A component loading hole 113a is provided in the center of the lid wall 113, and the component loading tray 14 is fixed so as to surround the component loading hole 113a. The component P1 is loaded from the component loading hole 113a into the accommodation space 114 of the rotary drum 11 through the component loading tray 14. The accommodation space 114 is also provided with a guide plate 115 that guides the component P1 toward the filter 12 that is a member for discharging as the rotating drum 11 rotates.

  The filter 12 is a substantially rectangular parallelepiped member attached to the peripheral wall 111 of the rotary drum 11 and extending in the tangential direction of the peripheral wall 111. Inside the filter 12, when the component P <b> 1 that changes its posture in the housing space 114 in the rotating drum 11 that is rotating is in a predetermined desirable posture suitable for work on the production line. A component discharge passage, which will be described later, is provided. Then, the component P1 in a posture capable of passing through the component discharge path is discharged through the component discharge path as the rotary drum 11 rotates. The filter 12 will be described in detail later.

  The guide rail 13 is a member that guides the component P1 discharged from the filter 12 to the component supply location 1a while maintaining the posture at the time of discharge. The guide rail 13 includes a receiving port 131 for the component P1 and a long rail portion 132. The receiving port 131 has a C-shaped cross section, and extends in an arc shape along the peripheral wall 111 of the rotating drum 11 as shown in FIG. The receiving port 131 is configured such that the filter 12 passes through the inside thereof as the rotating drum 11 rotates. When passing through the receptacle 131, the component P1 falls from the filter 12 to the inside of the receptacle 131. The rail part 132 has a C-shaped cross section, and extends with a downward slope from the receiving port 131 to the component supply place 1a. The component P1 that has fallen to the receiving port 131 is slid down to the component supply location 1a inside the rail portion 132 while being held between the pair of side walls of the rail portion 132 and maintaining the posture at the time of dropping.

  The parts feeder 1 is configured such that a rotating drum 11, a guide rail 13, a component supply tray 14, and a drum driving unit 15 are supported on a structure in which a plurality of support poles 16 are combined.

  3A to 3C are diagrams showing the filter shown in FIGS. 1 and 2. 3A shows an upper surface of the filter 12 facing the accommodation space 14 side of the rotary drum 11, and FIG. 3B shows a cross section taken along line V12-V12 in FIG. 3A. FIG. 3C shows a plan view when the filter 12 is viewed from the direction of arrow V13 in FIG. 3A. 4A to 4C are schematic views showing a state in which parts having desirable postures pass through the filters shown in FIGS. 3A to 3C. FIG. 4A shows a state in which the part P1 is taken into the filter 12, and FIG. 4B shows a state in which the taken part P1 passes through the filter 12. FIG. 4C shows a plan view of the filter 12 through which the component P1 is passing when viewed from the direction of the arrow V13 in FIG. 4B.

  Although the detailed description is omitted here, the component P1 has a shape in which the protruding portion P12 protrudes from one end side of the long band plate portion P11. The protrusion P12 is formed to be narrower than the band plate portion P11, and the component P1 has an outline shape in plan view from the direction of the arrow V13 in FIG. 4B as shown in FIG. 4C. It has an inverted T shape. As an example of the component P1 having such a shape, for example, a cable clamp having a band plate portion fixed along the cable and a protrusion fixed at the installation location of the cable can be cited.

  The filter 12 of this embodiment has a component discharge path 121 and a component take-in part 122. The component discharge path 121 is a passage that extends in the tangential direction D12 of the peripheral wall 111 and reaches the opening 121a outside the rotary drum 11 when the filter 12 is attached to the peripheral wall 111 of the rotary drum 11. And the cross-sectional shape of the component discharge path 121 is a substantially inverted T-shape corresponding to the contour shape of the component P1.

  The part taking-in part 122 of the filter 12 is a part that opens to the inside of the accommodation space 114 when the filter 12 is attached to the peripheral wall 111 of the rotating drum 11 and takes in the part P1 from the opening 122a. The component take-in part 122 follows the curved path 122b shifted from the extension line 121c of the component discharge path 121 to the inlet 121b of the component discharge path 121, and in the direction of the arrow D13 as shown in FIG. 4B. The component P1 is guided to the component discharge path 121.

  Here, in the present embodiment, as shown in FIGS. 4A and 4B, the component P1 has both left and right ends in plan view from the direction of the arrow V14 in FIG. 4C perpendicular to the direction of the arrow V13. Have different shapes. That is, the protrusion P12 is provided on the left end side in the drawing, and the strip plate portion P11 extends on the right end side. And as for this component P1, the attitude | position which makes the edge part side where the strip board part P11 extends the front side of the sending direction in this parts feeder 1 becomes a desirable attitude | position. However, it is needless to say that this desirable posture is a posture in which the protrusion P12 is directed upward, that is, toward the inside of the accommodation space 114 so as to be able to pass through the component discharge path 121.

  The component take-in portion 122 guides the component P1 with the end portion side from which the strip plate portion P11 extends toward the inlet 121b of the component discharge passage 121 to the component discharge passage 121 according to the desired posture. On the other hand, the part P1 with the other end directed toward the inlet 121b of the part discharge path 121 is returned to the inside of the rotary drum 11 without passing through the part discharge path 121.

  FIG. 5A to FIG. 5C are diagrams schematically illustrating three cases in which components are returned to the inside of the rotary drum in the component taking-in part of the filter. 5A shows the first case, FIG. 5B shows the second case, and FIG. 5C shows the third case.

  In the first case shown in FIG. 5A, the component P1 has the end side from which the strip plate portion P11 extends facing the inlet 121b of the component discharge path 121. However, the vertical direction in the figure is opposite to the direction shown in FIG. 4C that can pass through the component discharge path 121. Therefore, in the first case, the component P1 cannot enter the inlet 121b of the component discharge path 121, and is returned to the inside as the rotating drum 11 continues to rotate.

  In the second case shown in FIG. 5B, the vertical direction of the component P1 in the drawing coincides with the direction shown in FIG. 4C that can pass through the component discharge path 121. However, the component P <b> 1 has the end side where the protrusion P <b> 12 is provided facing the inlet 121 b of the component discharge path 121. As a result, the protrusion P12 interferes with the inlet 121b in the component take-in portion 122, the component P1 cannot be bent along the curved path 122b shown in FIG. 5B, and is returned to the inside when the rotary drum 11 continues to rotate. .

  Also in the third case shown in FIG. 5C, the component P <b> 1 has the end side where the protrusion P <b> 12 is provided facing the inlet 121 b of the component discharge path 121. In the third case, in the component P1, the vertical direction in the figure is opposite to the direction that can pass through the component discharge path 121, and cannot enter the inlet 121b of the component discharge path 121. Similarly to the second case, the curved path 122b cannot be bent. As a result, even in the third case, when the rotating drum 11 continues to rotate, it is returned to the inside.

  In the parts feeder 1 of the present embodiment described above, the filter 12 has the component discharge path 121 having a cross-sectional shape corresponding to the above contour shape when the component P1 is in a desirable posture. It is discharged through the component P1 in a posture capable of passing. Thereby, components can be sent out in the desirable posture.

  Here, in the present embodiment, as described above, the component P1 has different shapes between the left and right ends in the plan view from the direction of the arrow V14 in FIG. 4C, and the belt plate portion P11 extends. A posture in which the end side is the front of the delivery is desirable. In this embodiment, the filter 12 follows the curved path 122b shifted from the extension line 121c of the component discharge path 121 to the component discharge path 121, and the component P1 having a desirable posture that can pass through the path is supplied to the component discharge path 121. The component taking-in part 122 which leads to is provided. As a result, the condition that the part take-in part 122 can pass to the part discharge path 121 is added to the condition that the part discharge path 121 can pass, and the part shape that can pass can be defined in three dimensions. As a result, the accuracy of sending out the component P1 in a desired posture by the filter 12 is improved. Thus, according to the parts feeder 1 of this embodiment, components can be sent out in a desirable posture with high accuracy.

  Further, in the parts feeder 1 of the present embodiment, the part P1 in which the end side from which the strip plate part P11 extends is directed to the part discharge path 121 in the part take-in part 122 described above is passed to the part discharge path 121. Is possible. As a result, it is possible to send the component P1 with a high accuracy and a desired posture, which is difficult to send with a desired posture with high accuracy only by the component discharge path 121, such as a posture in which the end side is in front of the feeding.

  Moreover, in the parts feeder 1 of this embodiment, the component taking-in part 122 traces the curved path 122b from the opening 122a opened toward the central axis 114a of the accommodation space 114 of the rotating drum 11 to the component discharge path 121. The component P1 is guided. As a result, in the curved path 122b, if the posture is desirable, the component P1 can pass to the component discharge path 121 without interfering with the peripheral portion. However, in other postures, the peripheral portion and the component P1 interfere with each other. It is configured.

  And in this embodiment, the length of the component taking-in part 122 is shortened by such a curved path 122b compared with the case where the path | route reaching the component discharge path 121 is a path | route extended substantially straight, for example. That is, the length of the filter 12 in the tangential direction of the peripheral wall 111 of the rotary drum 11 is shortened. This also leads to shortening of the receiving port 131 that receives the component P1 discharged from the filter 12 in the guide rail 13, so that the material cost can be reduced.

  Next, a second embodiment will be described. In the second embodiment, the filter is different from the filter 12 of the first embodiment described above. On the other hand, the schematic configuration of the parts feeder is the same as the schematic configuration of the parts feeder of the first embodiment described with reference to FIGS. 1 and 2. Therefore, in the following, regarding the second embodiment, description of the schematic configuration of the parts feeder will be omitted, and a filter which is a difference will be described. In the following, the components of the parts feeder 1 shown in FIGS. 1 and 2 will be referred to without particular notice.

FIG. 7A shows a state in which the part P2 is taken into the filter 21, and FIG. 7B shows a state in which the taken part P2 passes through the filter 21. 8A and 8B are plan views when the filter and components are viewed from a cross section taken along line V24-V24 in FIG. 7B and from the direction of arrow V22 in FIG. 7B. 8A shows a cross section taken along line V24-V24, and FIG. 8B shows a plan view when viewed from the direction of arrow V22.

  Although the detailed description is omitted here for the component P2 in the present embodiment, a rectangular plate portion P22 is provided at the center of the long strip plate portion P21, and a protruding portion P23 is provided at the center of the rectangular plate portion P22. Has the shape. The rectangular plate portion P22 is formed wider than the strip plate portion P21, and the protrusion P23 is formed narrower than the rectangular plate portion P22. The contour shape of the component P2 in plan view from the direction of the arrow V22 in FIG. 7B is such that the rectangular plate portion P22 and the protruding portion P23 are substantially inverted T-shaped as shown in FIGS. 8A and 8B. The plate part P21 and the rectangular plate part P22 have a substantially T-shaped shape. As an example of the component P2 having such a shape, for example, a cable clamp or the like can be cited as in the case of the component P1 in the first embodiment described above.

  The filter 21 of the present embodiment includes a component discharge path 211 and a component take-in part 212. The component discharge path 211 is a passage that extends in the tangential direction D12 of the peripheral wall 111 and reaches the opening 211a outside the rotary drum 11 when the filter 21 is attached to the peripheral wall 111 of the rotary drum 11. And in the components discharge path 211, the cross-sectional shape becomes the following shapes according to the outline shape of said components P2. That is, as shown in FIGS. 6D and 8A, the cross-sectional shape in the vicinity of the inlet 211b on the side opposite to the opening 211a is a substantially inverted T-shape in the upper part in the drawing according to the contour shape of the component P2. The lower part in the figure has a substantially T-shaped shape. Further, as shown in FIG. 6C and FIG. 8B, the cross-sectional shape from the entrance 211b to the exit-side opening 211a is the width of the rectangular plate portion P22 and the rectangular plate portion P22. And the protrusion P23 is a rectangular shape having a height corresponding to the combined height. The lower part of the figure has a substantially T-shape similar to that of the inlet 211b.

  The part taking-in part 212 of the filter 21 is a part that opens to the inside of the accommodation space 114 when the filter 21 is attached to the peripheral wall 111 of the rotating drum 11 and takes in the part P2 from the opening 212a. The oblique path 212b shifted from the extension line 211c of the component discharge path 211 is followed to the inlet 211b of the component discharge path 211, and as shown in FIG. 7B, to the component discharge path 211 in the direction of arrow D21. Lead the part P2.

  In the present embodiment, the component take-in portion 212 has a shape bent upward in the drawing on the rear end side in the delivery direction of the component P2. Further, the opening 212a is wide open to the inlet 211b of the component discharge path 211, and a pair of inner wall surfaces 212c extending in the delivery direction is inclined obliquely toward the narrow bottom portion 212d. The component P2 entering the opening 212a from the rear end side is guided along the oblique path 212b to the bottom portion 212d by the bent shape of the rear end side and the inner wall surface 212c, and reaches the inlet 211b of the component discharge path 211. At this time, an inclination suppressing portion 212e is provided on the rear end side of the bottom portion 212d to guide the component P2 to the inlet 211b of the component discharge path 211 while suppressing the inclination around the center of the contour shape. The inclination suppression part 212e is a chevron-shaped rib, extends in the delivery direction of the part P2, and suppresses the inclination of the part P2 by pushing up the band plate part P21 from the bottom inside the part taking-in part 212.

It has a shape. That is, the part P2 has no distinction for an operator who receives the part P2 even if the part P2 is in a posture in which the left or right end side is the front side in the sending direction of the parts feeder 1 in the plan view. In the present embodiment, in order to efficiently take in such a component P2, the component taking-in portion 212 having a wide opening as described above is provided. Since the opening 212a is wide and the inside of the component taking-in portion 212 is a space having a relatively large margin for the component P2, there is little restriction on the movement. Therefore, the bending as in the first embodiment is performed. The skew path 212b is traced instead of the path 122b.

  The part P2 of this embodiment has no distinction of desirability in the left-right direction in the plan view shown in FIG. However, it is needless to say that the posture in which the rectangular plate portion P22 and the projection portion P23 are directed upward, that is, the inside of the accommodation space 114 of the rotary drum 11 so as to pass through the inlet 211b of the component discharge path 211 is a desirable posture. Yes.

  In the present embodiment, the component P2 in a desirable posture that can pass through the inlet 211b of the component discharge path 211 passes into the component discharge path 211. On the other hand, the part P2 that cannot pass through the inlet 211b is returned to the inside of the rotary drum 11.

The part P2 is mentioned. The component P2 in such a posture cannot return to the inside due to the strip plate portion P21 and the rectangular plate portion P22 interfering with the inlet 211b of the component discharge path 211, and is returned to the inside of the rotary drum 11.

  In the second embodiment described above, it is needless to say that the component P2 can be sent out in the desired posture by the filter 21 as in the first embodiment described above.

  Further, in the present embodiment, the component take-in portion 212 follows the skew path 212b from the opening 212a that opens toward the central axis 114a of the accommodation space 114 in the rotary drum 11 to the component discharge path 211b, and moves the component P2. It has become a guide. Thereby, the length of the component taking-in part 212, ie, the length of the filter 21, is shortened.

  In the present embodiment, the component take-in portion 212 is provided with an inclination suppressing portion 212e that suppresses the inclination around the center of the contour shape of the component P2 and guides the component P2 to the component discharge path 211. As a result, it is possible to suppress a situation in which the component P2 once taken in a posture capable of passing through the component discharge path 211 is laid down, for example, in front of the inlet 211b of the component discharge path 211 by the component pickup unit 212. As a result, it can be sent to the component discharge path 211 with a desired posture with high accuracy.

  In the first case shown in FIG. 13A, the component P3 has the end side from which the strip plate portion P32 extends faces the inlet 311b of the component discharge path 311. For this reason, the part P3 interferes with the edge of the opening 312a of the part taking-in part 312, cannot pass through the opening 312a, and is returned to the inside of the rotary drum 11.

  In the second case shown in FIG. 13B, the component P3 has the end opposite to the strip plate portion P32 facing the inlet 311b of the component discharge path 311 and the opening 312a of the component take-in portion 312. It is possible to pass. However, since the groove P311 faces the side opposite to the inclination suppressing part 312c in the component take-in part 312, the block part P31 interferes with the inclination suppressing part 312c and cannot pass any further, so that the rotating drum 11 Returned inside.

  In the third embodiment described above, it is needless to say that the component P3 can be sent out in the desired posture by the filter 31 as in the first embodiment described above.

It has a substantially inverted T shape with a part protruding in the left-right direction. Further, the component P4 has different shapes between the left and right ends in a plan view from a direction orthogonal to the arrow V44 direction in FIG. 15A. That is, a pair of lower flanges P41 corresponding to the overhangs in the substantially inverted T-shaped shape is provided at the lower portion at the right end in the drawing. Furthermore, an upper flange P42 projecting upward is provided on the upper right side in the drawing. The component P4 has a desirable posture in which the upper flange P42 faces the inner side of the rotary drum 11 and the upper flange P42 and the lower flange P41 face rearward in the delivery direction. An example of the component P4 having such a shape includes a connector housing.

  The filter 41 of this embodiment has a component discharge path 412 and a component take-in part 411. The component discharge path 412 is a path that extends in the tangential direction D12 of the peripheral wall 111 and reaches the opening 412a outside the rotary drum 11 when the filter 41 is attached to the peripheral wall 111 of the rotary drum 11. And the cross-sectional shape of the component discharge path 412 is a substantially inverted T-shape corresponding to the contour shape of the component P4 from the inlet 412b to the opening 412a.

  The part taking-in part 411 of the filter 41 is a cylindrical part that takes in the part P4 from the opening 411a that opens in the circumferential direction of the peripheral wall 111 when the filter 41 is attached to the peripheral wall 111 of the rotating drum 11. The cross-sectional shape of the passage of the component P4 in the component take-in portion 411 is also a substantially inverted T-shape corresponding to the contour shape of the component P4 from the opening 411a toward the inlet 412b of the component discharge path 412. However, the component take-in part 411 follows the step path 411b shifted from the extension line 412c of the component discharge path 412 in the radial direction of the rotary drum 11 from the opening 411a to the inlet 412b of the component discharge path. Lead.

  In the radial direction of the rotary drum 11, the step path 411 b is a path closer to the central axis 114 a of the accommodation space 114 of the rotary drum 11 than the inlet 412 b of the component discharge path on the side of the opening 411 a of the component take-in portion 411. In order to guide the part P4 through such a step path 411b, a step slope 411c reaching the inlet 412b is provided on the part discharge path of the part take-in portion 411 on the inlet 412b side.

  The part P4 is taken in from the opening 411a of the part taking-in part 411 in the direction of arrow D41 shown in FIG. 15A. Then, the component P4 is guided by various guide shapes provided on the stepped slope 411c and the inner wall surface of the component take-in portion 411 and enters the inlet 412b of the component discharge path 412 in the direction of arrow D42 shown in FIG. 15B. And passes through the inside in the direction of arrow D43.

  In the present embodiment, the component P4 having the desirable posture described above passes into the component discharge path 412. On the other hand, the parts P4 in other postures are returned to the inside of the rotary drum 11.

  FIG. 16 is a diagram schematically illustrating a case where components are returned to the inside of the rotary drum in the filter. FIG. 16A shows the first case, and FIG. 16B shows the second case.

  In the first case shown in FIG. 16A, the component P4 has the upper flange P42 and the lower flange P41 facing rearward in the delivery direction, but has the upper flange P42 facing the outside of the rotating drum 11. That is, in the first case component P4, the vertical posture in the figure is opposite to the above-described desirable posture. For this reason, the part P4 interferes with the edge of the opening 411a of the part taking-in part 411, cannot pass through the opening 411a, and is returned to the inside of the rotary drum 11.

  In the second case shown in FIG. 16B, the component P4 has the same vertical posture as the above-described desirable posture in the drawing, and can pass through the opening 411a of the component take-in portion 411. ing. However, the component P4 has the upper flange P42 and the lower flange P41 directed toward the inlet 412b of the component discharge path 412. For this reason, when the component P4 passes through the step in the step path 411b, it interferes with the step slope 411c and the inner wall surface of the component take-in portion 411 and cannot pass through the step. As a result, the part P4 is returned to the inside of the rotary drum 11 from the opening 411a of the part taking-in part 411.

  In the fourth embodiment described above, it is needless to say that the component P4 can be sent out in the desired posture by the filter 41, as in the first embodiment described above.

  In this embodiment, the stepped portion between the component take-in portion 411 and the component discharge path 412 can pass through the component P4 without interfering with the peripheral portion if it is in a desirable posture. P4 is configured to interfere. As a result, it is possible to pass / cannot pass between the desired posture and other postures even with respect to the part P4 that is difficult to realize a curved path or a skew path that can be passed in a preferred posture due to its shape. A distinction is provided.

  Next, a fifth embodiment will be described. The fifth embodiment is different from the first embodiment described above in that a component is added in the middle of the guide rail that guides the parts discharged from the filter. On the other hand, other components such as a filter are the same as those in the first embodiment. Hereinafter, the fifth embodiment will be described by paying attention to differences from the first embodiment.

  FIG. 17 is an external perspective view showing a parts feeder according to a fifth embodiment of the present invention. In FIG. 17, the same components as those shown in FIGS. 1 and 2 are denoted by the same reference numerals as those shown in FIGS. Description is omitted.

  The parts feeder 5 of this embodiment also includes a rotating drum 11, a filter 12, a guide rail 13, a component supply tray 14, a drum driving unit 15, and a plurality of support poles 16 that support these. . The component P <b> 1 is loaded into the accommodation space 114 of the rotary drum 11 through the component loading tray 14. When the rotary drum 11 is rotationally driven in the direction of the arrow D11 by the drum driving unit 15, the interior of the filter 12 is moved when the component P1 that is constantly changing the posture inside the accommodating space 114 has a desired posture. It passes through and is discharged. The discharged component P1 is received by the receiving port 131 of the guide rail 13, and slides down to the component supply place 5a inside the long rail portion 132.

  Here, in the present embodiment, the component supply place 5a is provided with a take-out detection sensor 51 that detects take-out of the component P1 from the component supply place 5a. When the operator takes out the component P1 from the component supply location 5a, the removal detection sensor 51 detects that fact. The detection result is sent to a stopper 52 described below. The stopper 52 is provided in the middle position 5 b of the rail portion 132 in the guide rail 13. The stopper 52 stops the part P1 that is discharged from the filter 12 and moves on the rail portion 132 at the midway position 5b. Furthermore, the stopper 52 sends out the component P1 to the component supply location 5a according to the detection result of the removal detection sensor 51. In the present embodiment, each time the take-out detection sensor 51 detects the takeout of one part P1, the stopper 52 sends out one piece P1.

  FIG. 18 is an enlarged view of the stopper shown in FIG.

  As shown in FIG. 18, the stopper 52 includes an actuator 521 and a holding plate 522. The holding plate 522 is supported by the actuator 521 so as to intersect the rail portion 132 of the guide rail 13. The actuator 521 holds the holding plate 522 by blocking the movement of the component P1 from the rotary drum 11 side and holds the component P1, and retracts from the holding position in the direction of arrow D51 and passes the component P1. It is held so as to be freely rotatable between positions. When the detection result indicating that the removal of one component P1 is detected by the removal detection sensor 51 is sent, the actuator 521 rotates the holding plate 522 to the retracted position by the arrow D51. As a result, the part P <b> 1 passes below the holding plate 522. After passing, the actuator 521 returns the holding plate 522 to the component holding position.

  Here, in the present embodiment, the auxiliary plate 523 is disposed on the rear side of the holding plate 522 in the delivery direction of the component P1. When the holding plate 522 is positioned at the component holding position, the auxiliary plate 523 is provided below the auxiliary plate 523 so that one component P1 can pass therethrough. Further, the auxiliary plate 532 is provided so as to stop the movement of the component P1 when the holding plate 522 is located at the retracted position.

  When the holding plate 522 is moved to the retracted position, the auxiliary plate 523 rotates together with the holding plate 522. At this time, one component P1 is sent out under the holding plate 522 in the retracted position. At the same time, the auxiliary plate 523 stops the movement of the subsequent component P1. For this reason, the number of parts P1 sent out when the holding plate 522 is rotated is limited to one.

  After the delivery of one component P1, when the holding plate 522 is restored to the component holding position, the subsequent component P1 that has passed under the auxiliary plate 523 is held by the holding plate 522. This state is maintained until the removal of the next component P1 is detected by the removal detection sensor 51.

  According to the parts feeder 5 of the fifth embodiment described above, in addition to being able to send out the part P1 in a desired posture with high accuracy, the part P1 is replenished in accordance with the removal from the part supply location 5a. Thereby, efficient component supply according to the use pace of component P1 can be performed.

  In addition, embodiment described above showed only the typical form of this invention, and this invention is not limited to this embodiment. That is, various modifications can be made without departing from the scope of the present invention. Of course, such modifications are included in the scope of the present invention as long as the configuration of the parts feeder of the present invention is provided.

  For example, in the above-described first to fourth embodiments, as an example of the component discharge path referred to in the present invention, four types of cross-sectional component discharge paths corresponding to the contour shapes of the four components P1,. 121, 211, 311 and 412 are illustrated. However, the part discharge path referred to in the present invention is not limited to these, and the cross-sectional shape thereof can be appropriately designed according to the contour shape of the target part, and the specific shape is not questioned.

  Further, in the first to fourth embodiments described above, as an example of the component taking-in portion referred to in the present invention, four types of inner surface shape taking-in components corresponding to the shapes of the four types of components P1,. The parts 122, 212, 312, and 412 are illustrated. However, the part taking-in part said to this invention is not restricted to these, About the inner surface shape, it can design suitably according to the shape of the component made into object, and does not ask | require a specific shape.

  Further, in the above-described fifth embodiment, as an example of the stopper, the stopper 52 that feeds out one component P1 each time the removal of the component P1 is detected by the removal detection sensor 51 is illustrated. However, the stopper here is not limited to this. For example, the stopper may repeat the above-described operation a plurality of times and continuously send out a plurality of components each time one extraction of the component is detected by the extraction detection sensor. Alternatively, one part may be sent out each time a plurality of parts taken out are detected by the take-out detection sensor, or the same number of parts are sent out each time a plurality of parts are detected. It is good. It is possible to appropriately set how many parts are to be sent out at what timing.
