Description

  The present invention relates to a posture control device for a component such as a projection nut that tends to be in an abnormal posture such as standing or turning.

  As a component supply device that tends to be in an abnormal posture as described above, there is a technique disclosed in Japanese Patent No. 3326490. FIG. 8 and FIG. 9 of this publication show a temporary fixing chamber provided with a stopper member that communicates with the component supply passage and receives the entry of the component, and accepts the component delivered from the temporary fixing chamber and temporarily fixes it. There is disclosed a component supply device having a holding recess formed in a supply rod that moves forward and backward while facing a chamber.

On the other hand, Japanese Patent No. 2852490 discloses the use of a member that can be advanced and retracted to form a temporary fixing chamber for a bolt that has moved in a supply passage.
Japanese Patent No. 3326490 Japanese Patent No. 2852490

  The technique disclosed in Patent Document 1 has the following problems. That is, when the projection nut that has entered the temporary stop chamber collides with the stopper member, a phenomenon occurs in which the nut bounces up and stands up or reverses. If an abnormal posture is caused by such a phenomenon, it becomes impossible to transfer the nut to the holding recess in a normal posture. If the nut is transferred to the holding recess while being inverted, the nut is supplied to the target location with the supply rod in the reverse direction, and normal welding cannot be performed.

  In order to solve such a problem, it is desired to utilize the space existing between the temporary fixing chamber and the holding recess in some way.

  On the other hand, the technique disclosed in Patent Document 2 has the following problems. That is, since the advanceable / retractable member forms a temporary fixing chamber of the bolt, the function of preventing the bolt from bouncing back to an abnormal posture is not fulfilled. In other words, since the elongated bolt enters the temporary fixing chamber formed of a member that can advance and retract, the bolt itself does not take an abnormal posture.

  In addition, this document does not suggest anything about a solution for the extremely small space between the temporary fixing chamber and the holding recess. In other words, the space between the supply rod and the bolt temporarily locked by the member that can be advanced and retracted at the front end of the supply passage is set to be extremely large. It has not been.

  The present invention is provided in order to solve the above-described problems. Even if there is a space limitation, a regulating member that reliably prevents a component from being in an abnormal posture is successfully arranged to provide reliable operation. An object is to provide a highly functional device.

  Next, the best mode for carrying out the component attitude control device in the component supply device of the present invention will be described.

  1 to 3 show a first embodiment.

  The parts supplied in the present invention are intended to stand up or turn over like a projection nut or washer. In this embodiment, the projection nut 1 is made of iron. This will be explained with reference to FIG. 1B. The projection nut 1 has a square shape as shown in FIG. 4 and is provided with welding projections 3 at the four corners of the back side 2 at the center. A screw hole 4 is formed. A blocking member 6 is attached to the screw hole opening on the front side 5. Hereinafter, the projection nut may be simply expressed as a nut.

  A supply passage 8 is constituted by a component supply pipe 7 extending from a parts feeder (not shown). The supply passage 8 is rectangular in cross section so that the nut 1 does not reverse in the supply passage 8. The temporary fixing chamber 9 for temporarily locking the nut 1 communicates with the supply passage 8, and a member constituting a part of the inner surface of the temporary fixing chamber 9 is a stopper member 10.

  The tip of the component supply pipe 7 is coupled to a substantially rectangular parallelepiped block member 11 by welding or the like, and the stopper member 10 is similarly fixed to the block member 11. An upper part of the tip of the component supply pipe 7 is cut away to form an open part 12 through which the nut 1 is sent out from the temporary fixing chamber 9. A permanent magnet 30 is embedded in the stopper member 10 in order to position the nut 1 in the temporary fixing chamber 9.

  A supply rod 13 is provided to advance and retract the nut 1 to reach the target location. A holding recess 14 for receiving the nut 1 is provided at the tip of the supply rod 13, and a receiving / opening portion 15 for the nut 1 to enter is formed. Therefore, the opening part 12 of the temporary fixing chamber 9 and the receiving / opening part 15 of the holding recess 14 are opposed to each other.

  A support member that supports the supply rod 13 in a state in which the supply rod 13 is accommodated therein is constituted by an outer cylinder 16. Although not shown, an air cylinder is coupled to the end of the outer cylinder 16, and its piston rod is coupled to the supply rod 13. The supply rod 13 is advanced and retracted by the output of the air cylinder.

  A connecting piece 17 provided on a part of the block member 11 is welded to an end of the outer cylinder 16, thereby establishing a facing relationship between the temporary fixing chamber 9 and the holding recess 14. In such a facing relationship, a gap 18 is formed between the temporary fixing chamber 9 and the holding recess 14, and the gap dimension of the gap 18 (the dimension in the thickness direction of the gap) is the length of the coupling piece 17. Set by adjusting.

  The space 18 has a flat space shape, and extends between the temporary fixing chamber 9 and the holding recess 14 along the direction in which the nut 1 enters the temporary fixing chamber 9 and the direction in which the supply rod 13 advances and retreats. It is a flat space that expands. In FIG. 3, the dimension of the gap 18 in the thickness direction is greatly illustrated for easy understanding.

  As is clear from FIG. 1A, which is a front view of the apparatus, and FIG. 2, which is a plan view thereof, a state where the entering direction of the nut 1 with respect to the temporary fixing chamber 9 and the advancing and retracting direction of the supply rod 13 are substantially perpendicular to each other. It is said that.

  An air cylinder 19 is attached to the lower side of the block member 11, and a push rod 20 that is advanced and retracted by the air cylinder 19 is inserted into the guide hole 21. A through hole 22 through which the push rod 20 passes is formed at the bottom of the component supply pipe 7 so that the flat upper end surface of the push rod 20 can be in close contact with the lower surface of the nut 1, that is, the front side 5.

  When the push rod 20 advances, the nut 1 is pushed up by the upper end surface of the push rod 20 and is transferred from the temporary fixing chamber 9 through the opening 12 and the receiving opening 15 into the holding recess 14. At this time, a permanent magnet 23 is arranged to promote introduction of the nut 1 into the holding recess 14. The permanent magnet 23 is embedded in a holding piece 24 welded to the front end of the outer cylinder 16.

  In order to prevent the nut 1 in the holding recess 14 from dropping when the supply rod 13 advances, a permanent magnet 25 is arranged. The permanent magnet 25 is separated from the nut 1 when the supply rod 13 has advanced to the target location. For this purpose, the permanent magnet 25 is coupled to an inner shaft 26 that advances and retracts in the supply rod 13. Although not shown, when the supply rod 13 reaches the target location, the inner shaft 26 is pulled and the permanent magnet 25 is separated from the nut 1. For this reason, the magnetic attractive force acting on the nut 1 substantially disappears, so that the nut 1 falls to the target location.

  The target location here is a receiving hole 28 provided in the upper part of the fixed electrode 27. As shown by a two-dot chain line in FIG. 3, when the supply rod 13 is extended and the permanent magnet 25 is retracted, the nut 1 is dropped into the receiving hole 28. A movable electrode 29 is arranged coaxially with the fixed electrode 27.

  Next, the restriction member will be described.

  The nut 1 that has entered the temporary fixing chamber 9 at a high speed from the supply passage 8 collides with the stopper member 10 and is received. At the time of this collision, the nut 1 may be bounced off from the stopper member 10 and may stand upright or be reversed and turned over. It is necessary to suppress such behavior of the nut 1 so that the nut 1 does not turn abnormally.

  In order to prohibit the abnormal turning as described above, the restricting member 32 is disposed so as to advance and retract in the gap 18. As clearly shown in FIG. 3, the restricting member 32 is made of a flat plate member 33. The regulating member 32 is arranged so as to advance and retreat in the surface direction, and advances and retreats in the same direction as the advancing and retreating direction of the supply rod 13. That is, in FIG. 1A, it advances and retreats in the direction perpendicular to the paper surface. Accordingly, the flat plate-like regulating member 32 is advanced and retracted in a state where the flat plate-like regulating member 32 is inserted into the flat space as described above. When the restricting member 32 is inserted into the gap portion 18, the opening portion 12 of the temporary fixing chamber 9 is covered so that the nut 1 cannot stand up in the temporary fixing chamber 9. At the same time, since it cannot stand, it cannot be reversed.

  As shown in FIG. 2, the restricting member 32 includes an insertion portion 34 that enters the gap portion 18 and a coupling portion 35 that is integrated with the insertion portion 34, and has a substantially L-shape. Thus, the coupling portion 35 is a member that extends in a direction in which the nut 1 enters the temporary fixing chamber 9. An air cylinder 36, which is a forward / backward drive means, is fixed to the outer portion of the outer cylinder 16, and its piston rod 37 is advanced and retracted in the same direction as the supply rod 13. An end portion of the coupling portion 35 is fixed to the piston rod 37. Therefore, when the air cylinder 36 outputs an advance / retreat, the insertion portion 34 enters and exits the gap portion 18.

  In this embodiment, as shown in FIG. 2, the distal end side of the insertion portion 34 has a bifurcated shape, but it is also possible to stop such bifurcation.

  As described above, the restricting member 32 is formed in an L shape by the insertion portion 34 that enters the gap portion 18 and the coupling portion 35 that extends in the entry direction of the nut 1, and the coupling portion 35 is fixed to the outer cylinder 16. Since the cylinder 36 is configured to advance and retract in the same direction as the supply rod 13, the function of restricting the nut 1 can be ensured only by adopting the L-shaped plate-like component and the air cylinder 36 fixed to the outer cylinder 16. Therefore, the abnormal turning of the nut 1 can be prevented with a simple structure, and the abnormal turning of the nut 1 can be prohibited only by adding the simple structure to the existing component supply device.

  The operation of the first embodiment will be described.

  First, the regulating member 32 is advanced to cover the open portion 12 of the temporary fixing chamber 9. In this state, the nut 1 enters the temporary fixing chamber 9 at a high speed and collides with the stopper member 10. At this time, the nut 1 is bounced back by the stopper member 10 and tries to change in an abnormal direction. However, since the restricting member 32 covers the temporary fixing chamber 9, there is no space for the nut 1 to stand up, and the nut 1 It is attracted to the permanent magnet 30 in a normal posture as it enters, and stops at a predetermined position in the temporary fixing chamber 9. Thereafter, the regulating member 32 escapes from the gap portion 18 by the air cylinder 36.

  Then, when the push rod 20 is raised by the operation of the air cylinder 19, the nut 1 moves into the holding recess 14 and is attracted by the permanent magnet 25 to be positioned in the holding recess 14. Thereafter, the supply rod 13 advances and stops above the fixed electrode 27, the permanent magnet 25 moves backward, and the nut 1 is dropped into the receiving hole 28. Then, the supply rod 13 moves backward to prepare for receiving the next nut. Although not shown, a steel plate part is placed on the nut 1 supported by the receiving hole 28, and the movable electrode 29 is advanced on the nut 1 to press the steel plate part and the welding projection 3, so that the welding current is increased. The welding projection 3 is welded by energization.

  The functions and effects of the embodiment described above are listed as follows.

  A regulating member 32 that regulates abnormal turning such as standing and reversing of the projection nut 1 that has entered the temporary fixing chamber 9 can be advanced and retracted in the gap 18 between the temporary fixing chamber 9 and the holding recess 14. Arranged in a state. As described above, since the restriction member 32 is arranged using the gap portion 18, it is possible to reliably suppress the abnormal turning of the nut 1 in the temporary fixing chamber 9.

  Further, even if the space between the temporary fixing chamber 9 and the holding recess 14 is small, by selecting the shape of the regulating member 32 arranged in the gap portion 18, the regulating member 32 is arranged in a narrow place. Therefore, it is possible to perform a precise regulation operation.

  Further, since the gap 18 between the temporary fixing chamber 9 and the holding recess 14 is used, the regulating member 32 can be easily and inexpensively made without any special design change or modification to the existing component supply device. Can be installed. And since the space | gap part 18 is utilized, the advancing / retreating operation | movement of the control member 32 can be performed easily, and it is effective also for structure simplification.

  The entering direction of the nut 1 with respect to the temporary fixing chamber 9 and the advancing / retreating direction of the supply rod 13 are substantially perpendicular to each other, and the restricting member 32 is configured to advance / retreat in the same direction as the advancing / retreating direction of the supply rod 13.

  Since the insertion portion 34 of the restriction member 32 advances and retreats in the same direction as the supply rod 13, the restriction member 32 (insertion portion) avoids interference with the supply passage 8 that allows the nut to enter the temporary fixing chamber 9. 34) can be arranged. With such an arrangement, it is possible to additionally arrange the regulating member 32 in the gap 18 without affecting neighboring members, and therefore it is not necessary to make special design changes or modifications to the existing component supply device. It becomes.

  Advancing / retreating means for moving the regulating member 32 back and forth in the same direction as the advancing / retreating direction of the supply rod 13, that is, an air cylinder 36, is attached to the outer side of the outer cylinder 16 which is a support member that supports the supply rod 13 in the accommodated state. .

  Since an air cylinder 36 for advancing and retracting the restriction member 32 in the same direction as the advancing and retreating direction of the supply rod 13 is attached to the outer portion of the outer cylinder 16, this air cylinder 36 is additionally attached to the existing outer cylinder 16. Therefore, the restricting member 32 can be moved in the forward / backward direction of the supply rod 13 without any special modification. Moreover, since the air cylinder 36 is attached to the outer side part of the outer cylinder 16, attachment of the air cylinder 36 is easy and the advancing / retreating means can be arranged in a compact state.

  The restriction member 32 is constituted by a flat plate member 33, and the restriction member 32 is configured to advance and retract in the plane direction of the flat plate.

  Since the flat plate member 33 advances and retreats in the surface direction, the space required for the restricting member 32 to advance and retreat is minimized. Therefore, even if it is the above-mentioned narrow gap 18, the regulating member 32 can advance and retreat without hindrance, and the application of the regulating member 32 to an existing component supply device is easily realized.

  FIG. 4 shows a second embodiment.

  In this embodiment, the advancing / retreating direction of the regulating member 32 is changed. That is, the restricting member 32 is configured to advance and retract in the same direction as the nut transfer direction of the supply passage 8. Here, the air cylinder 36 is fixed to the upper surface of the component supply pipe 7, and its piston rod 37 is coupled to the regulating member 32. That is, in FIG. 1, the regulating member 32 enters the gap 18 from the left side of the paper surface, and in FIG. 3, the regulating member 32 enters the gap portion 18 from the direction perpendicular to the paper surface.

  Alternatively, the restricting member 32 can be advanced and retracted from the right side of FIG. Since the other configuration is the same as that of the previous embodiment, members having the same function are denoted by the same reference numerals.

  With the above configuration, the restricting member 32 advances and retreats in the same direction as the direction in which the nut 1 enters, so that the restricting member 32 can be disposed avoiding interference with the advance and retreat operation of the supply rod 13. With such an arrangement, it is possible to additionally arrange the regulating member 32 in the gap 18 without affecting neighboring members, and thus it is not necessary to make a special modification to the existing component supply device. Other functions and effects are the same as in the previous embodiment.

  FIG. 5 shows a third embodiment.

  In this embodiment, the operating direction of the regulating member 32 is a swinging direction type. The swing arm 40 is supported by a stationary pivot 41, a regulating member 32 is fixed to one end, and a piston rod 43 of an air cylinder 42 is coupled to the other end. Since other configurations are the same as those of the previous embodiments, members having the same function are denoted by the same reference numerals.

  With the above configuration, the restricting member 32 swings in the surface direction by the advance / retreat output of the air cylinder 42 to cover or open the opening portion 12 of the temporary fixing chamber 9. Because of such a swinging type, it is possible to employ a regulating member 32 adapted to various aspects of the component supply device. Other functions and effects are the same as those of the previous embodiments.
