  Next, the best mode for carrying out the component supply pipe support device of the present invention will be described.

  The overall arrangement of the device of the present invention will be described.

  As shown in FIG. 1C, a synthetic resin supply hose 42 is connected to a delivery pipe 44 of a parts feeder 41 which is a component supply source. An extended end of the supply hose 42 is connected to a stopper unit 43 as a component. The parts are transferred to the stopper unit 43 by the blast air from the air blast pipe 45 attached to the delivery pipe 44. The supply hose 42 is made of urethane resin.

  A component handled in this embodiment is a projection nut 5 as shown by a solid line in FIG. 1A or a two-dot chain line in FIG. The projection nut 5 is a general one in which a nut body has a square shape, a screw hole is formed at the center thereof, and welding projections are provided at four corners on one side of the square portion. In the following description, the projection nut may be simply expressed as a nut.

  The parts feeder 41 is of a type that feeds from the transfer path of the circular vibrating bowl to the delivery pipe 44. As another type, the parts feeder 41 adsorbs a predetermined number of parts with a magnet attached to the rotating plate and removes it from the delivery path. Various things can be employed, such as one that is sent out, or one in which a part is moved to the transport path by a rotating disk and the part is sent out from the transfer path.

  In this embodiment, the nut 5 is welded to the steel plate part 46 placed on the fixed electrode 40, and the movable electrode 39 is arranged in a pair with the fixed electrode 40. When the nut 5 from the parts feeder 41 is sent by air injection to the component supply pipe support device 101 and supplied onto the steel plate component 46 by the supply rod 1 of the component supply device 100, the movable electrode 39 advances and the nut 5 is moved. The steel plate part 46 is welded by electric resistance welding.

  Next, the component supply device 100 and the component supply pipe support device 101 will be described.

  A supply rod 1 that moves forward and backward passes through the metal guide tube 2, and a metal guide tube 3 is integrated with the tip of the guide tube 2 by welding or the like. Is formed. The supply rod 1 is a guide rod 7 inserted into a screw hole of the projection nut 5, a sliding rod 8 having a larger diameter than the guide rod 7, and an extrusion surface disposed at the boundary between the guide rod 7 and the sliding rod 8. 9. The guide tube 3 is an arc-shaped tube member having a rectangular cross section. The guide tube 3 is a metal joint tube having a relatively short length as shown in the figure and a rectangular cross section at the end. 10 is welded, and the guide pipe 3 and the joint pipe 10 communicate with each other in the form of a component supply passage 23.

  The supply rod 1, the guide tube 2, the guide tube 3, and the joint tube 10 are made of metal, and the material thereof is, for example, stainless steel. The component supply device 100 is attached by connecting the support rod 47 fixed to the guide tube 2 to the stationary member 48.

  A guide plate 11 is formed at the end of the guide tube 2 in the extending direction of the guide tube 3 to constitute one inner wall of the temporary fixing chamber 4, and a magnet (permanent magnet) 12 is embedded therein. An air cylinder 15 is coupled to the guide cylinder 2, and the piston rod of the air cylinder 15 is connected to the supply rod 1, so that the supply rod 1 is moved back and forth.

  As described above, the supply head 16 is mainly composed of the supply rod 1, the guide tube 2, the guide tube 3, the temporary fixing chamber 4, the guide plate 11, and the like. When the supply rod 1 advances, the guide rod 7 is inserted into the screw hole, and the projection nut 5 is pushed out by the extrusion surface 9 to supply the nut 5 to the electrode pin (not shown) of the fixed electrode 40 which is the target location. To do.

  As shown in FIGS. 1A and 2, the joint pipe 10 is integrally provided with a joint 18 that joins a long support member 17 to the supply head 16 by welding or the like. The coupling portion 18 is provided with a support hole 20 through which the support member 17 is slidably penetrated in an elongated block type main body 19, and a fixing bolt 21 for fixing the support member 17 in the support hole 20 is screwed into the main body 19. As shown in FIG. 2, the support member 17 is strongly pressed by the tip of the fixing bolt 21 so that the support member 17 and the main body 19 are integrated.

  As shown in FIG. 2, the tip of the component supply tube 22 is inserted into the joint tube 10, and a component supply passage 23 extending from the component supply tube 22 to the guide tube 3 is configured. The component supply pipe 22 is made of a synthetic resin material, for example, urethane resin, has flexibility to form a required piping posture, and has a rectangular cross section. The dimensions of the projection nut 5 passing therethrough are rectangular shapes with a length and width of about 10 mm and a height of about 5 mm, respectively. The cross-sectional shape of the support member 17 is circular, and its diameter is about 5 mm. The support member 17 is made of, for example, a soft iron bar so that the operator can bend it into a required shape by hand.

  As shown in FIGS. 1A, 1B, and 3, the support member 17 is disposed along the component supply pipe 22, and a holding portion 24 that holds the component supply pipe 22 is provided at the tip thereof. It has been. The holding portion 24 is formed by connecting a fixing bracket 26 having a hat-shaped cross section to a metal substrate 25 such as stainless steel to which an end portion of the support member 17 is welded by a fixing bolt 27, and the component supply pipe 22 is a fixing bracket. 26 is held by the substrate 25 in a state of penetrating the inside of the substrate 26. In other words, the distal end portion of the support member 17 is fixed to the component supply pipe 22 via the holding portion 24.

  Further, the component supply pipe 22 is also fixed in the connecting portion 18 with the same structure. As shown in FIG. 2, a fixing bracket 29 having a hat-shaped cross section is coupled to a substrate 28 welded to the joint pipe 10 by a fixing bolt 30, and the component supply pipe 22 penetrates the inside of the fixing bracket 29. It is fixed to.

  Next, the stopper unit 43 will be described.

  FIG. 1B is a view taken in the direction of arrow B in FIG. The nut 5 that has been transferred into the supply hose 42 by the air jetted from the air jet pipe 45 collides with the temporary fixing chamber 4 at a high speed. Therefore, the inner surface of the guide plate 11 is damaged or the supply rod 1 is damaged. In order to solve such a problem, the stopper unit 43 is arranged.

  A stopper unit 43 is provided integrally with the holding portion 24, and this stopper unit 43 is connected to a synthetic resin supply hose 42 having one end connected to the component supply pipe 22 and the other end extending from the parts feeder 41. A metal unit pipe 50 and an advancing / retracting stopper member 51 for stopping the nut 5 that has entered the unit pipe 50 and has been transferred through the supply hose 42 at a high speed.

  The unit pipe 50 is made of stainless steel, and its cross-sectional shape is rectangular, like the component supply pipe 22 and the supply hose 42. The substrate 25 of the holding part 24 and the unit tube 50 are joined at a welded part 49. The stopper member 51 may have any shape that can enter the unit tube 50 and receive the nut 5, and is formed of a round bar-like member here. An air cylinder 52 is fixed to the unit pipe 50 via a cylindrical distance piece 53 in order to advance and retract the stopper member 51. The stopper member 51 shown here is constituted by a piston rod of the air cylinder 52. Air for advancing and retracting the stopper member 51 is sucked and discharged by air hoses 54 and 55 connected to the air cylinder 52.

  The connecting portion between the unit tube 50 and the supply hose 42 has the same structure as the holding portion 24 between the component supply tube 22 and the unit tube 50. Therefore, the same reference numerals as those of the members constituting the holding portion 24 are shown in FIG.

  When the nut 5 is pneumatically conveyed from the delivery pipe 44 of the parts feeder 41, it is necessary to expel the air in front of the nut 5 to facilitate the transfer of the nut 5. For this purpose, a plurality of exhaust ports 56 are usually provided in the supply hose 42. However, when the stopper member 51 enters the unit pipe 50, the stopper member 51 reduces the air flow area of the unit pipe 50, so the nut 5 that has passed through the exhaust port 56 and the stopper member 51 The exhaust performance of the air is worse. As a result, the transfer speed of the nut 5 that has passed through the exhaust port 56 is reduced, and smooth nut transfer is hindered. Therefore, a long hole-like exhaust port 57 is provided slightly behind the stopper member 51 when viewed in the nut transfer direction. The exhaust port 57 is also illustrated in FIG. By providing such an exhaust port 57, even if the stopper member 51 significantly reduces the flow path area of the unit pipe 50, there is an effect that the nut transfer is smoothly performed without decelerating.

  Next, the sensor will be described.

  The number of nuts waiting in the guide pipe 3 and the component supply pipe 22 is increased so that the shortage of nuts does not occur when the supply rod 1 has a short advance / retreat operation cycle. Further, when the period is long, the standby number is set to be small so as to avoid useless nut feeding operation and to make the operation of the apparatus as economical as possible. In order to meet such a demand, a sensor capable of adjusting the mounting position is disposed in the component supply pipe.

  A sensor 31 for detecting the projection nut 5 in the component supply pipe 22 is fixed to the outer surface of the component supply pipe 22. Various sensors can be used as the sensor 31. Here, the sensor 31 is a proximity switch having a rectangular parallelepiped shape, and is integrated with the component supply pipe 22 by a fixed band 32. When the fixing band 32 is loosened, the position of the sensor 31 can be moved in the longitudinal direction of the component supply pipe 22.

  When changing the above-mentioned waiting number, the attachment position of the sensor 31 is changed. In order to prevent the obtained attachment position of the sensor 31 from shifting, the positioning member 33 is provided on the support member 17. . That is, the positioning structure portion 33 is moved along the support member 17 to integrate the positioning structure portion 33 with the support member 17, and then the sensor 31 is fixed to the position of the positioning structure portion 33. Alternatively, the positioning structure 33 and the sensor 31 may be moved together to integrate the positioning structure 33 with the support member 17, and then the sensor 31 may be fixed to the component supply pipe 22.

  1 and 2 show a state in which the support member 17 is firmly coupled to the coupling portion 18 to support the component supply pipe 22 and the stopper unit 43. At this time, since the tip end portion of the support member 17 is coupled to the component supply pipe 22 via the holding portion 24, the piping posture of the component supply pipe 22 is maintained as prescribed by the rigidity of the support member 17. When changing the piping posture of the component supply pipe 22, the fixing bolt 21 of the coupling portion 18 is loosened to bend the support member 17 so that the curved shape of the component supply pipe 22 is as predetermined, and then the fixing bolt 21 is tightened again. When the support member 17 is bent together with the component supply pipe 22, the support member 17 is displaced with respect to the support hole 20, so that the fixing bolt 21 is loosened or tightened. Therefore, the shift | offset | difference of said support member can also be absorbed by the holding | maintenance part 24 side. Alternatively, the shift of the support member 17 may be absorbed by both the holding portion 24 and the support hole 20.

  The number of standbys of the nut 5 that moves smoothly with the correct piping posture can be set to the optimal number of standbys according to the speed of supply and consumption of the nuts 5 by the supply rod 1, so that parts can be supplied without shortage of nuts. Realize. In order to avoid shortage of nuts, when the length of the waiting line of the nuts 5 is shortened, the sensor 31 detects this and a command signal for nut replenishment operation is issued to the parts feeder (not shown). Yes.

  The long support member 17 is disposed along the component supply pipe 22, and the holding portion 24 of the component supply pipe 22 and the stopper unit 43 are provided at the end of the support member 17. By making this long member, the operator can appropriately deform the support member 17 and freely select the piping posture of the component supply pipe 22. For example, when supplying a nut to a projection welder, there are various members around the component supply pipe 22, so it is important to set the piping posture while avoiding them successfully. In such a case, the piping posture can be selected without any inconvenience in the present invention. Further, since the holding portion 24 is disposed at the end of the support member 17, the component supply pipe 22 is supported at two spaced locations, that is, at the connecting portion between the holding portion 24 and the supply head 16. It is effective to increase the support stability.

  In addition, since the stopper unit 43 is structurally arranged in a continuous form with the holding portion 24, each structure of the supply head 16, the support member 17, the holding portion 24, and the stopper unit 43 is formed as a series of elongated structural systems. To do. Therefore, a structure along the component supply passage 23 is formed, and the slim component supply pipe support device 101 including the stopper unit 43 is obtained.

  Since the length of the support member 17 is adjusted by the adjustment structure portion 35 including the main body 19, the support hole 20, the fixing bolt 21, and the like disposed in the coupling portion 18, the holding portion 24 suitable for the piping posture of the component supply pipe 22. Can be selected. Therefore, the piping posture of the component supply pipe 22 is made in an optimal deformed shape of the support member 17, and the component supply pipe 22 can be stably supported.

  Since the component supply pipe 22 is joined to the metal guide pipe 3 via the joint pipe 10 and the joint 18 is attached to the joint pipe 10, the joint between the part supply pipe 22 and the guide pipe 3 is ensured. In addition, the support member 17 is securely fixed in a stable state by the coupling portion 18 fixed to the metal guide tube 3 side.

  A specific structure of the positioning structure will be described.

  As shown in FIGS. 1A and 1B and FIG. 4, the positioning structure 33 can move along the support member 17 and can be fixed to the support member 17. And an engaging member 36 which is coupled to the moving member 34 and engages with the sensor 31 to set the relative position between the sensor 31 and the moving member 34 to a predetermined positional relationship.

  The moving member 34 is a tube member 38 that is entirely or partially tubular, and the support member 17 passes through the tube member 38 so that the position of the tube member 38 can be adjusted. The tube member 38 and the support member 17 are integrated with a screwed fixing bolt 37, and an engagement member 36 that engages with the sensor 31 is coupled to the tube member 38. The pipe member 38 has a tubular shape over the entire length or only a part thereof, and the illustrated one is formed in a tubular shape over the entire length.

  The engagement member 36 serves to maintain the normal position of the sensor 31 and the tube member 38 integrated with the support member 17. Various structures can be used for this purpose. For example, the sensor 31 is disposed between two projecting members projecting from the tube member 38 so that the sensor 31 does not shift along the component supply tube 22. Alternatively, as shown in FIG. 1B, an elongated wire is bent into a U-shape and joined to the pipe member 38 by welding or the like to form a square frame.

  The tube member 38 is moved along the support member 17 and stopped at the required number of standby positions of the nut, and then the fixing bolt 37 is tightened to integrate the tube member 38 with the support member 17. Thereafter, the sensor 31 is fitted into the rectangular frame-shaped engaging member 36 and is brought into close contact with the component supply pipe 22 and fixed by the fixing band 32. Alternatively, the fixing member 37 may be tightened or the fixing band 32 may be tightened by moving the pipe member 38 and the engaging member 36 and the sensor 31 together.

  Next, the operation system of the nut transfer and the stopper unit will be described.

  FIG. 5 is an overall view of the operating system. A control device 59 for inputting various signals and outputting an operation signal to an operation control valve or the like is provided, and a signal from the sensor 31 is input. The control device 59 is generally used, and can be easily operated by using, for example, a simple sequencer circuit or a computer device.

  An operation signal from the control device 59 is input to the air switching valve 60, and operating air therefrom is supplied to the air injection pipe 45 and the air cylinder 52. The operation signal from the control device is set so that the air injection from the air injection pipe 45 and the advancing operation of the air cylinder 52 in which the stopper member 51 enters the unit pipe 50 are performed simultaneously. That is, the operation of the stopper member 51 entering the unit pipe 50 and the air injection for transferring the nut 5 through the supply hose 42 at high speed are synchronized.

  Therefore, when the sensor 31 detects that the number of waiting nuts is insufficient, the signal is input to the control device 59, and the replenishment nut is transferred by air injection. When the replenishing nut is being transferred, the parts feeder 41 vibrates in response to an operation signal from the control device 59. When the waiting number of nuts is satisfied, a satisfaction signal is input to the control device 59, air injection is stopped, and the delivery vibration of the parts feeder 41 is stopped.

  In the above-described operation, the nut 5 transferred at high speed is received by the stopper member 51 waiting in the unit pipe 50, and the impact is alleviated. Thereafter, when the stopper member 51 moves backward, the nut 5 moves toward the guide tube 3 by its own weight and reaches the temporary fixing chamber 4 at a low speed.

  Although various air cylinders are employed in the above-described embodiments, an electric motor that performs forward / backward output may be employed instead.

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

  As described above, the metal support member 17 is coupled to a part of the supply head 16, the metal holding portion 24 is coupled to the end portion thereof, and the stopper unit 43 is integrally formed with the holding portion 24. Since they are provided, each structure of the supply head 16, the support member 17, the holding portion 24, and the stopper unit 43 is formed as a series of elongated structural systems. Therefore, a structure along the component supply passage 23 is formed, and the slim component supply pipe support device 101 including the stopper unit 43 is obtained.

  The stopper unit 43 has a metal unit pipe 50 connected at one end to the component supply pipe 22 and the other end connected to a supply hose 42 extending from the parts feeder 41, and enters the unit pipe 50. Thus, the unit pipe 50 is used as a joint member between the component supply pipe 22 and the supply hose 42 because the stopper member 51 is configured to stop the nut 5 that has been transferred through the supply hose 42 at a high speed. In addition to functioning, it serves as a base member for mounting the stopper member 51. Therefore, the stopper unit 43 is multifunctionally arranged at the end portion of the series of structural systems with a small space, thereby preventing the supply head 16 and the supply rod 1 from being damaged by the fast moving nut 5. .

  A sensor 31 for detecting the number of nut standby parts in the part supply pipe 22 is attached to the part supply pipe 22, and the attachment position of the sensor 31 is set by a positioning structure portion 33 that can be adjusted along the support member 17. It was configured as follows.

  The number of nuts waiting in the component supply pipe 22 is increased so that the shortage of nuts does not occur when the supply rod 1 has a short advance / retreat operation cycle. Further, when the period is long, the standby number is set to be small so as to avoid useless nut feeding operation and to make the operation of the apparatus as economical as possible. In order to meet such a demand, the mounting position of the sensor 31 is adjusted. This adjustment should be made as simple as possible and the adjusted position should not be easily deviated.

  With the above-described configuration, the positioning structure 33 can be adjusted along the support member 17, thereby determining the position of the sensor 31, so that the position of the sensor 31 suitable for the standby number can be set appropriately. Thus, the request can be satisfied.

  The positioning structure portion 33 is coupled to a moving member 34 that can move along the support member 17 and can be fixed to the support member 17, and the moving member 34, that is, the tube member 38. The engaging member 36 is engaged with the sensor 31 to set the relative position between the sensor 31 and the moving member 34 to a predetermined positional relationship.

  By moving the moving member 34 along the supporting member 17 and then fixing the moving member 34 to the supporting member 17, the engaging member 36 engages with the sensor 31, and the mounting position of the sensor 31 can be accurately set. That is, since the frame member is formed by the tube member 38 and the engaging member 36, even if the sensor 31 positioned inside the tube member 38 attempts to be displaced, the displacement is prevented by the frame member. . Alternatively, the sensor 31 and the moving member 34 can be moved together to fix the sensor 31 to the component supply pipe 22, and then the moving member 34 can be fixed to the support member 17.

  The operation of the stopper member 51 entering the unit pipe 50 and the injection of the blast air that moves the nut 5 through the supply hose 42 at high speed are synchronized.

  With the configuration described above, the nut 5 that is conveyed by air moves the supply hose 42, so that the nut 5 reaches the stopper member 51 after the stopper member 51 enters the unit pipe 50. Therefore, when the nut 5 reaches, the stopper member 51 always enters the unit pipe 42 and is in a standby state, and the stop operation is reliably achieved.

  In the above-described first embodiment, the stopper unit 43 is included in a series of structural systems of the supply head, the support member, and the holding unit. In Example 2, a series of the supply head, the support member, and the holding unit is included. In the structure system, that is, in the structure system not including the stopper unit 43, the positioning structure portion 33 is present.

  Therefore, the specific structure of the second embodiment is established in a form in which the stopper unit 43 is removed from the structure of the first embodiment. That is, the unit tube 50 is not connected to the holding portion 24 but the supply hose 42 is connected. Although such a structure is not illustrated, it can be easily implemented. Other configurations are the same as those in the first embodiment.

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

  The number of nuts waiting in the component supply pipe 22 is increased so that the shortage of nuts does not occur when the supply rod 1 has a short advance / retreat operation cycle. Further, when the period is long, the standby number is set to be small so as to avoid useless nut feeding operation and to make the operation of the apparatus as economical as possible. In order to meet such a demand, the mounting position of the sensor 31 is adjusted. This adjustment should be made as simple as possible and the adjusted position should not be easily deviated.

  With the above-described configuration, in a series of structural systems in which the metal support member 17 is coupled to a part of the supply head 16 and the metal holding unit 24 is coupled to the end portion thereof, the positioning structure unit 33 is supported by the support member 17. Thus, the position of the sensor 31 can be determined accordingly, so that the position of the sensor 31 suitable for the waiting number can be set appropriately, and the request can be satisfied.

  The positioning structure portion 33 is coupled to a moving member 34 that can move along the support member 17 and can be fixed to the support member 17, and the moving member 34, that is, the tube member 38. The engaging member 36 is engaged with the sensor 31 to set the relative position between the sensor 31 and the moving member 34 to a predetermined positional relationship.

  By moving the moving member 34 along the supporting member 17 and then fixing the moving member 34 to the supporting member 17, the engaging member 36 engages with the sensor 31, and the mounting position of the sensor 31 can be accurately set. That is, since the frame member is formed by the tube member 38 and the engaging member 36, even if the sensor 31 positioned inside the tube member 38 attempts to be displaced, the displacement is prevented by the frame member. . Alternatively, the sensor 31 and the moving member 34 can be moved together to fix the sensor 31 to the component supply pipe 22, and then the moving member 34 can be fixed to the support member 17.

  The moving member 34 is a tube member 38 that is entirely or partially tubular, and the support member 17 passes through the tube member 38 so that the position of the tube member 38 can be adjusted. The tube member 38 and the support member 17 are integrated with a screwed fixing bolt 37, and an engagement member 36 that engages with the sensor 31 is coupled to the tube member 38.

  The tube member 38 is moved along the support member 17 to adjust the position, and then integrated with the support member 17 with a fixing bolt 37. As a result, a predetermined position of the engaging member 36 is set. By attaching the sensor 31 to this position, the number of waiting nuts suitable for the forward / backward movement state of the supply rod 1 can be set. Thus, the positioning of the sensor 31 can be performed easily and accurately. Further, since it is the tube member 38, it can be easily moved to a predetermined position along the support member 17, and the engaging member 36 coupled to the tube member 38 has a shape such as, for example, between two protrusions. The sensor 31 can be disposed in the frame 31 or the sensor 31 can be surrounded by the frame-shaped engagement member 36, and the engagement member 36 adapted to the form of the sensor 31 can be obtained. Other functions and effects are the same as in the previous embodiment.

  As described above, according to the present invention, it is a component supply pipe support device that can freely set the piping posture, reduce the impact of the components that are transferred at high speed, and perform positioning of the sensor for detecting the components. It can be used in a wide range of industrial fields such as automobile body welding processes and home appliance sheet metal welding processes.
