  The problem of abnormal interference described above frequently occurs in a shaft-like component having a flange-like member. When the interference of the flange-shaped member occurs between the shaft-shaped part stopped at the temporary stop position and the subsequent shaft-shaped part, the shaft-shaped part waiting at the temporary stop position is transferred toward the exit passage. However, in some cases, the flange-like members are engaged with each other, and the parts cannot be transferred to the outlet passage. Such interference between the flange-like members has such a characteristic that, since the parts are shaft-shaped, the shaft-shaped portion swings and assumes an inclined posture.

  As described above, an object of the present invention is to solve the interference problem caused by the shaft-like component having the flange-like member swinging during transfer.

According to the first aspect of the present invention, there is provided an apparatus for supplying a shaft- like component having a flange-like member, including a head, a shaft formed integrally with the head, and a flange at a boundary between the head and the shaft. A shaft-shaped part provided with a shaped member is to be supplied, and a transfer passage in which the inlet passage and the outlet passage of the shaft- shaped part communicate with each other is provided in the case body, and a lid member is attached to the case body. The inlet passage and the transfer passage are formed in parallel to the left and right of the lower portion of the passage space through which the shaft portion passes, the passage space through which the head portion passes, and the flange-like member slide and the head portion passes. A moving stop means is provided which is constituted by a sliding surface and temporarily stops in a state where the shaft-like component is displaced upward in the axial direction at a position where the transfer passage enters the transfer passage from the entrance passage. Passing through the head at The space in the vertical direction of the space between the temporary stop and the space between them is set to be larger than the vertical dimension constituted by the head and flange-like member, and the axial component displaced upward at the temporary stop position by this dimension setting The head portion of the subsequent shaft-shaped component is abutted against the flange-shaped member of the shaft, and the shaft-shaped component stopped in a state of being displaced upward is transferred along the transfer passage toward the outlet passage. The transfer member which can be advanced / retracted is provided.

Since the shaft-like component is displaced upward in the axial direction by the movement stop means, the flange-like member is also displaced upward accordingly , whereby the flange-like member with the flange-like member of the subsequent shaft-like component is exchanged. Interference can be avoided. Accordingly, only one axial component displaced upward in the axial direction is smoothly transferred toward the outlet passage by the transfer member. That is, the flange-like member of the subsequent shaft-like component enters the lower side of the flange-like member of the shaft-like component stopped at the temporary stop position. Therefore, the head of the subsequent shaft-shaped component hits the flange-shaped member of the shaft-shaped component stopped at the temporary stop position, and abnormal interference does not occur between the two shaft-shaped components.

  The shaft-shaped component supply device having a flange-like member according to the present invention as set forth in claim 2 is characterized in that the movement stop means is a magnet attached to a lid member at a position corresponding to a temporary stop position. It is a supply device of a shaft-like component provided with a flange-like member. With this configuration, the shaft-shaped component is displaced to the position where the shaft-shaped component is attracted to the inner surface of the lid member at the temporary stop position by the magnetic attraction during the transitional period when the shaft-shaped component enters the temporary stop position. Therefore, the shaft-like component is reliably displaced and a highly reliable function is obtained, and interference between the flange-like members does not occur as described above.

  According to a third aspect of the present invention, there is provided a supply device for a shaft-shaped component including a flange-shaped member, wherein a passage space through which a shaft portion of the shaft-shaped component passes and a sliding surface on which the flange-shaped member of the shaft-shaped component slides, 3. An apparatus for supplying a shaft-like component having a flange-like member according to claim 1 or 2, provided in a transfer passage, an inlet passage connected to the transfer passage, and a supply guide member connected to the inlet passage. It is. Thus, the passage space through which the shaft portion of the shaft-shaped component passes and the sliding surface on which the flange-shaped member of the shaft-shaped component slides are formed in a series on the transfer passage, the inlet passage, and the supply guide member. Therefore, the shaft-like component is smoothly transferred.

  According to a fourth aspect of the present invention, there is provided the supply device for a shaft-like component provided with the flange-like member, wherein a suction means for sucking the shaft-like component to the temporary stop portion is provided in the case body near the temporary stop portion. It is a supply apparatus of the shaft-shaped components provided with the flange-shaped member as described in any one of Claims 1-3. Therefore, since the shaft-like component is quickly and reliably pulled into the temporary stop position by the suction means, the shaft-like component is reliably introduced into the predetermined location. Since the movement stopping means functions simultaneously with such introduction, it becomes impossible for the flange-like member of the subsequent shaft-like component to interfere with each other, and it is possible to supply a component with high operational reliability.

  Next, the best embodiment of the supply device for the shaft-like component provided with the flange-like member of the present invention will be described.

  1 to 7 show a first embodiment of an apparatus according to the present invention.

  FIG. 1 is a plan view of the entire apparatus, and is illustrated with a lid member described later removed in order to facilitate understanding of the internal structure. A flat upper surface 2 is formed on an elongated case body 1 having a substantially rectangular parallelepiped shape, and a plate-like lid member 3 is fixed thereto with bolts (not shown) in close contact therewith. In addition, the code | symbol 4 shown in FIG. 1 is a screw hole of the said volt | bolt.

  The target component in this embodiment is the bolt 5 having the structure shown in FIG. This is composed of a head portion 6 and a shaft portion 7 formed integrally with the head portion 6, and a circular flat washer 8 and a spring washer 9 are overlapped on the boundary between the head portion 6 and the shaft portion 7. Has been placed. The flat washer 8 is prevented from being removed by a screw thread. Such a flat washer 8 and a spring washer 9 correspond to a flange-like member, and there is a gap between the flat washer 8 and the spring washer 9, and the thickness is irregular when viewed in the rotational direction. It is the size.

  The (6)-(6) cross section of FIG. 1 is shown in FIG. This shows a cross-sectional shape of the inlet passage 10 and is formed by a groove-like passage space 11 through which the shaft portion 7 of the bolt 5 passes and a passage space 12 through which the head portion 6 passes. A sliding surface 13 on which the flat washer 8 slides is formed in a state parallel to the left and right in the lower part of the passage space 12 of the head 6.

  A supply guide member 14 shown in FIG. 5 is arranged in a state of being connected to the inlet passage 10. The supply guide member 14 guides the bolt 5 fed from a parts feeder (not shown) to the inlet passage 10, and the cross-sectional shape thereof is substantially the same as that of the inlet passage 10. The passage space and sliding surface of the supply guide member 14 are assigned the same reference numerals as those of the inlet passage 10. As apparent from FIG. 5, the flat washer 8 slides on the sliding surface 13, and the bolt 5 is just suspended, and moves from the supply guide member 14 to the inlet passage 10.

  An outlet passage 15 is formed in the vertical direction of the case body 1 (direction perpendicular to the paper surface of FIG. 1). The outlet passage 15 is formed by a hole having a circular cross section. In order to transfer the bolt 5 entering the inlet passage 10 to the outlet passage 15, a transfer passage 16 is provided. The cross-sectional shape of the transfer passage 16 is the same as the cross-sectional shape of the inlet passage 10, and the passage space and sliding surface of the shaft portion 7 and the head portion 6 of the bolt 5 are the same as the shape shown in FIG. The same reference numerals are described in FIG.

  The entrance passage 10 and the transfer passage 16 are orthogonal to each other, and the intersecting portion is a temporary stop portion 17. That is, a temporary stop point 17 is arranged at a point where the transfer passage 16 is entered from the inlet passage 10.

  Guide grooves 18 are formed in the case body 1 in the transfer direction of the transfer passage 16, that is, in the left-right direction in FIG. 1. The guide groove 18 is formed in a state in which the passage space 11 of the transfer passage 16 is extended straight to the right in FIG. 1, and the transfer member 19 is inserted into the guide groove 18 in a slidable state. An air cylinder 20 is coupled to the end of the case body 1, and its piston rod 21 is coupled to the end of the transfer member 19. When the air cylinder 20 operates and the piston rod 21 advances, the transfer member 19 enters the transfer passage 16 and the bolt 5 is transferred.

  A magnet (permanent magnet) 22 is embedded in the case body 1 corresponding to the extending direction of the supply guide member 14, that is, the contact position of the inlet passage 10. The magnet 22 is arranged to attract the bolt 5 from the inlet passage 10 to the temporary stop point 17. In other words, the magnet 22 is arranged in the vicinity of the temporary stop point 17. The case body 1 is made of stainless steel, which is a non-magnetic material, in order to make the magnetic force of the magnet 22 act strongly on the bolt 5.

  “Moving stop means” is provided for temporarily stopping the bolt 5 that has entered the temporary stop portion 17 while being displaced in the axial direction. As shown in FIG. 4, the movement stop means functions to pull up the bolt 5 located at the temporary stop point 17. Here, a magnet (permanent magnet) 23 is embedded in the lid member 3. is there. The magnet 23 is attached to the lid member 3 at a position corresponding to the temporary stop portion 17, and the position of the magnet 23 viewed in a plan view is indicated by a reference numeral 23 in FIG. 1. Note that the lid member 3 is made of stainless steel, which is a non-magnetic material, in order to cause the magnetic force of the magnet 23 to act strongly on the bolt 5. Further, since the magnet 23 pulls up the bolt 5 in the axial direction, the magnetic force is set stronger than that of the magnet 22.

Since the bolt 5 is displaced upward in this way, the passage space 12 through which the head 6 of the bolt 5 of the inlet passage 10 passes and the space in the vertical direction of the temporary stop portion 17 connected thereto, as shown in FIG. It is set larger than the vertical dimension constituted by the head 6, the spring washer 9 and the flat washer 8. That is, a space for displacing the bolt 5 upward is formed from the entrance passage 10 to the temporary stop portion 17. Such a space is also formed in a continuous state in the transfer passage 16. As shown in FIG. 6, the cross-sectional shape of the transfer passage 16 is the same as the cross-sectional shape of the inlet passage 10, and includes the height dimension of the head 6 of the bolt 5 (the height dimension of the flat washer 8 and the spring washer 9). A dimension larger than () is given to the passage space 12.

  As shown in FIG. 1, when the transfer member 19 is most retracted, the pressing surface 24 (refer to FIG. 8) at the front end thereof looks into the temporary stop portion 17. As shown in FIG. 8, the first slope 25 is formed to prevent interference with the subsequent bolt 5. A second slope 26 is formed below the first slope 25. The second inclined surface 26 is set to have a longer length than the first inclined surface 25 when viewed in the advancing and retracting direction of the transfer member 19. The vertical dimension of the second slope 26 is also set larger than that of the first slope 25. When supplying the long bolt 27, the second inclined surface 26 receives the lower end of the bolt 27 when the bolt 27 is inclined, as shown in FIG. It has a function to stand up by a simple action.

  FIG. 7 is an external view of the apparatus. An outlet pipe 28 communicating with the outlet passage 15 is attached to the lower side of the case body 1, and a delivery hose 29 is connected to the outlet pipe 28. In addition, an air hose 30 is connected to the lid member 3 in order to send out the bolt 5 that has entered the outlet passage 15 toward the outlet pipe 28.

  Next, the operation of this apparatus will be described. The bolt 5 that has slid the supply guide member 14 in the suspended state enters the inlet passage 10 as it is, is attracted by the magnet 22, and stops at the temporary stop portion 17. When the bolt 5 is approaching the temporary stop point 17, the head 6 of the bolt 5 is lifted by the magnet 23 on the lid member 3 side, and the head 6 is in close contact with the lower surface of the lid member 3 as shown in FIG. Then stop. Even if the next bolt 5 enters in this state, as shown in FIG. 4, the spring washer 9 and the flat washer 8 of the succeeding bolt 5 Enter the lower side of the flat washer 8. Therefore, the head 6 of the subsequent bolt 5 hits the flat washer 8 of the bolt 5 stopped at the temporary stop point 17, and no abnormal interference occurs between the two bolts 5.

  The above abnormal interference is illustrated in FIG. Here, since there is no means such as the magnet 23 for displacing the bolt 5 in the axial direction, the flat washers 8 of the two bolts 5 overlap each other.

  As shown in FIG. 4, when the transfer member 19 is advanced by the air cylinder 20 to the state where the head 6 is in close contact with the lower surface of the lid member 3, the pressing surface 24 becomes the shaft portion 7 of the bolt 5. The push bolt 5 moves toward the transfer passage 16 while rubbing against the lower surface of the lid member 3. When the head 6 of the bolt 5 moves away from the magnet 23, the bolt 5 is displaced downward by its own weight, and the flat washer 8 slides on the sliding surface 13 of the transfer passage 16. Then, when the bolt 5 is further moved by the transfer member 19, the bolt 5 enters the outlet passage 15 and is sent out toward the delivery hose 29 by the compressed air from the air hose 30.

  When the delivery to the delivery hose 29 is completed, the transfer member 19 is retracted by the air cylinder 20 and returned to the position of FIG. 1 to prepare for the subsequent transfer of the bolt 5.

  In the above embodiment, the magnets 22 and 23 are permanent magnets, but they can be changed to electromagnets. Further, although the magnet 23 is employed as the movement stopping means, as shown by a two-dot chain line in FIG. 4, the compressed air is injected from the air passage 31 opened in the case body 1 below the temporary stop portion 17. The magnet 23 can be abolished or its attractive force can be weakened.

  The effects of the above embodiment are listed as follows.

Since the bolt 5 is displaced in the axial direction upward by the magnet 23 is displaced to the upper side relative flange-like member such as a spring washer 9 and the flat washer 8 along with it, whereby subsequent bolt 5 spring washer Interference between the flange-like members such as 9 and the flat washer 8 can be avoided. Therefore, only one bolt 5 displaced upward in the axial direction is smoothly transferred toward the outlet passage 15 by the transfer member 19. That is, the flange-like members such as the spring washer 9 and the flat washer 8 of the subsequent bolt 5 enter the lower side of the flange-like member of the bolt 5 stopped at the temporary stop position. Therefore, the head 6 of the subsequent bolt 5 hits the flange-like member of the bolt 5 stopped at the temporary stop position, and no abnormal interference occurs between the bolts 5 and 5.

  The magnet 23 is attached to the lid member 3 at a position corresponding to the temporary stop point 17. With this configuration, the bolt 5 is displaced to the position where the bolt 5 is attracted to the inner surface of the lid member 3 by the attractive force of the magnet 23 during the transitional period when the bolt 5 enters the temporary stop portion 17. Therefore, the bolt 5 is reliably displaced and a highly reliable function is obtained, and the interference between the flange-like members does not occur as described above. Since the attracting force of the magnet 23 is set to be stronger than the attracting force of the magnet 22, the positive displacement is applied to the bolt 5.

  A passage space 11 through which the shaft portion 7 of the bolt 5 passes and a sliding surface 13 on which the flat washer 8 of the bolt 5 slides are provided in the transfer passage 16, the inlet passage 10 connected to the transfer passage 16, and the inlet passage 10. It is provided in the supply guide member 14 which continues. Thus, the passage space 11 through which the shaft portion 7 of the bolt 5 passes and the sliding surface 13 on which the flange-like member such as the spring washer 9 or the flat washer 8 of the bolt 5 slides are provided with the transfer passage 16, the inlet passage 10, and the like. Since the supply guide member 14 is formed with a series, the bolt 5 is smoothly transferred.

  A magnet 22 that attracts the bolt 5 to the temporary stop portion 17 is provided in the case body 1 in the vicinity of the temporary stop portion 17. Therefore, the bolt 5 is quickly and reliably pulled into the temporary stop portion 17 by the magnet 22, so that the bolt 5 is reliably introduced into a predetermined portion. Simultaneously with such introduction, the magnet 23 serving as the movement stop means functions, so that the flange-like members such as the spring washer 9 and the flat washer 8 of the subsequent bolt 5 cannot interfere with each other, and operation reliability is ensured. Highly reliable parts can be supplied.

  As described above, since the bolt 5 is displaced in the axial direction and temporarily stops, interference with the subsequent bolt does not occur. Therefore, the supply of the shaft-like parts to the welding device, the bolt tightening device, etc. is surely achieved, and it is used in a wide range of production fields, and a great marketability can be expected.
