Effect of the invention

  When a part is received in one relay pipe, the control device performs air injection on the part, and at the same time as the start of the air injection, the other relay pipe is opened at the outlet opening of the delivery control unit. The next part is received in conformity with the above, and an operation is performed so that air injection is performed on the received part. Therefore, almost simultaneously with one relay pipe performing air injection to start component conveyance, it is possible to transfer parts to another relay pipe and perform air injection. For this reason, since the delivery function from the relay pipe functions continuously without stopping, there is an effect that the parts are supplied and distributed efficiently.

The plurality of relay pipes are fixed to the substrate in a parallel state when viewed in the longitudinal direction, a coupling member is fixed to an end portion of the substrate, and the advancing / retreating driving means of the transition unit is arranged in a state of being laminated with the substrate. The output member of the advance / retreat driving means is fixed to the coupling member . The plurality of relay pipes are fixed to the substrate in a parallel state when viewed in the longitudinal direction, a coupling member is fixed to an end portion of the substrate, and the advancing / retreating driving means of the transition unit is disposed in a state of being laminated with the substrate. The output member is fixed to the coupling member so that the advance / retreat axis of the output member of the advance / retreat drive means is shifted perpendicular to the longitudinal direction of the relay pipe, and the advance / retreat drive means It is fixed to a stationary member, and the substrate is attached to the advance / retreat driving means through a slide mechanism in a state in which the substrate can advance / retreat in the same direction as the advance / retreat axis.

  Since the substrate and the advancing / retreating drive means are arranged in parallel as described above, the unit as the apparatus is good, and an apparatus that can be easily installed in a space-constrained place is obtained.

  Next, the best mode for carrying out the component distribution and supply device and the distribution and supply method of the present invention will be described.

  1 to 4 show a first embodiment.

  The part to be supplied in this embodiment is a projection nut. This has the shape shown in FIG. When viewed from above, the main body 2 has a square shape, and a screw hole 3 is formed in the center thereof, and welding projections 4 are provided at four corners on one side. In the following description, the projection nut 1 may be simply expressed as a nut.

  The overall structure of the distribution supply device will be described.

  The nuts 1 delivered from the parts feeder 5 are delivered one by one from the delivery control unit 6. The nut 1 is received by the relay pipe 7 and is transported to the destination by air injection. Although there are a plurality of relay pipes 7, two are provided here, and a flexible supply hose 8 is connected to each relay pipe 7. Two supply hoses 8 are configured to supply parts to two target locations. The target location here is a component supply device 10 having an advancing and retracting supply rod 9.

  Next, the transmission control unit will be described.

  A guide pipe 13 having a rectangular cross section is connected to the outlet pipe 12 of the parts feeder 5. The guide tube 13 is fixed to a stationary member 14 such as a machine frame. The guide tube 13 is inclined so that the traveling direction of the nut 1 is lowered. Stopping members 15 and 16 that enter the guide tube 13 are provided, and air cylinders 17 and 18 that advance and retreat them are provided. These air cylinders 17 and 18 are fixed to the guide tube 13 via brackets 19 and 20.

  FIG. 1 shows a state in which both stop members 15 and 16 have entered the guide tube 13. The restraining member 15 restrains the entire rear nut row, and the restraining member 16 restrains one front nut 1. Therefore, one nut 1 is held between both the restraining members 15 and 16. Here, when the restraining member 16 moves backward, one nut 1 is fed into the relay pipe 7. When the restraining member 16 enters again, the other restraining member 15 is retracted and one nut 1 is fed into the restraining member 16. Thereafter, the restraining member 15 enters again to restrain the nut row. When the outlet opening 21 of the guide pipe 13 matches the relay pipe 7, the nut 1 is smoothly transferred into the relay pipe 7.

  Next, the relay pipe will be described.

  A plurality of the relay pipes 7 are arranged. Here, there are two. The two relay pipes 7 are arranged to be inclined like the guide pipe 13 and are coupled to the substrate 23 in a state where the longitudinal directions thereof are parallel to each other. The substrate 23 is a flat plate member using a thick plate material. The substrate 23 is adapted to alternately correspond to the outlet opening 21 of the guide tube 13 by moving back and forth in a direction orthogonal to the longitudinal direction of the relay tube 7. A supply hose 8 is connected to both the relay pipes 7 to supply the nut 1 to the component supply device 10 which is a target location.

  In order to convey the nut 1 that has entered the relay pipe 7 at a high speed, an air injection port 24 is opened into the relay pipe 7, and an air hose 25 is connected thereto.

  Next, the transition unit will be described.

  The transition unit 26 has a function of alternately matching the relay pipes 7 to the outlet openings 21 of the guide pipes 13. As shown in FIG. 3, an air cylinder 27 that is an advancing / retreating drive unit is disposed in a state of being stacked on the substrate 23. That is, the air cylinder 27 is disposed below the substrate 23, and the forward / backward axis of the piston rod 28 is in a state of being perpendicular to the longitudinal direction of the relay pipe 7. The piston rod 28 is an output member of the advance / retreat driving means. A coupling member 29 is fixed to the end of the substrate 23, and a piston rod 28 is coupled thereto. The coupling member 29 is formed by welding a thick plate-like member to the end portion of the substrate 23 in a direction perpendicular to the end.

  Since the substrate 23 and the air cylinder 27 are arranged in such a positional relationship as described above, the arrangement of the substrate 23 and the length of the air cylinder 27 is not linearly added. There is an effect that the space in the left-right direction can be reduced.

  A slide mechanism 30 is provided to smoothly advance and retract the substrate 23 when the air cylinder 27 moves forward and backward. As the type of the slide mechanism 30, various types based on a guide rail structure can be adopted. An example is shown in FIG. FIG. 3C is a cross-sectional view taken along the line CC of FIG. A stationary-side guide rail 32 having a widened portion 31 is fixed on the upper surface of the air cylinder 27, and a movable-side slide rail 33 assembled in a slidable state is provided. The slide rail 33 is attached to the substrate 23. It is fixed. The slide rail 33 slides with respect to the guide rail 32 by the output of the air cylinder 27.

  Next, the component supply device will be described.

  The nut 1 delivered from the relay pipe 7 is supplied to the component supply device 10. There are various types of the component supply device 10, but here, the component supply device 10 is of a type using an advancing and retracting supply rod 9. A guide cylinder 35 is fixed to the stationary member 14, and a supply rod 9 passes through the guide cylinder 35. An air cylinder 36 is coupled to the end of the guide cylinder 35, and the supply rod 9 is advanced and retracted by the piston rod. A supply head 37 in which a temporary stop chamber is formed is coupled to the other end of the guide tube 35, and the nut 1 from the supply hose 8 is temporarily locked in a predetermined posture.

  The supply rod 9 is formed with a thin guide rod 38 that passes through the screw hole 3 of the nut 1, and is supplied in a state where the nut 1 is skewed. Here, the steel plate part 40 is mounted on the fixed electrode 39 of electric resistance welding, and the nut 1 is supplied to the guide pin 41 penetrating the steel plate part.

  Next, the control device will be described.

  The control device 42 is a general device that operates the entire device, and is configured by a simple computer device or a sequence circuit. The air switching valve 43 that operates in response to a signal from the control device 42, a sensor that emits a signal at a predetermined position such as the air cylinders 27, 17, 18, 36, and the like, and the air cylinder 18 that operates to be constant A predetermined operation is ensured by combining a timer device (not shown) that injects air from the air injection port 24 after time.

  The operations performed by the control device 42 are as follows. The air cylinder 27 is operated so that the relay pipe 7 on one side matches the outlet opening 21 of the guide pipe 13. Then, the air cylinder 18 moves backward and one nut 1 is sent to the relay pipe 7. Simultaneously with the backward movement of the air cylinder 18, the timer device starts timing, and air injection is performed when the nut 1 passes through the air injection port 24. Almost simultaneously with the air injection, the air cylinder 27 operates and the relay pipe 7 on the other side matches the outlet opening 21. After this match, air injection is performed when the nut 1 passes through the air injection port 24. Therefore, as soon as the nut 1 enters the relay pipe 7, air injection is performed, and at the same time, the other relay pipe 7 matches the outlet opening, and the same air conveyance is performed.

  It should be noted that an electric motor that performs forward / backward output can be employed instead of the various air cylinders.

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

  When the nut 1 is received in one relay pipe 7, the control device 42 injects air into the nut 1, and the other relay pipe 7 is operated by the operation of the transition unit 26 almost simultaneously with the start of the air injection. The next nut 1 is received in conformity with the outlet opening 21 of the delivery control unit 6, and the received nut 1 is operated so that air is injected. Therefore, almost simultaneously with one relay pipe 7 performing air injection to start nut conveyance, the nut 1 can be transferred to another relay pipe 7 and air injection can be performed. For this reason, since the delivery function from the relay pipe 7 functions continuously without stopping, there is an effect that the distributed supply of the nut 1 is efficiently performed.

The two relay pipes 7 are fixed to the substrate 23 in parallel with each other when viewed in the longitudinal direction, and a coupling member 29 is fixed to the end of the substrate 23. An air cylinder 27 as a driving means is arranged, and a piston rod 28 as an output member of the air cylinder 27 is fixed to the coupling member 29. Then, the plurality of relay pipe 7 is fixed to the substrate 23 in parallel with a look at its longitudinal direction, the binding members 29 are secured to the ends of the substrate 23, the interworking unit 26 in a state of being laminated with the substrate 23 The air cylinder 27 is disposed, and the piston rod 28 is connected to the coupling member 29 so that the advancing and retreating axis of the air rod 27 is perpendicular to the longitudinal direction of the relay pipe 7. The air cylinder 27 is fixed to the stationary member 14, and the substrate 23 is attached to the air cylinder 27 via a slide mechanism 30 in a state where the substrate 23 can advance and retract in the same direction as the advance / retreat axis.

  Thus, since the board | substrate 23 and the air cylinder 27 are arrange | positioned in the positional relationship which overlapped in parallel, the unity as an apparatus becomes favorable and the apparatus easy to install in the location with space restrictions is obtained.

  As described above, according to the present invention, a parts distribution supply device and a distribution supply method that can continuously supply parts from a plurality of relay pipes to a plurality of target locations. It can be used in a wide range of industrial fields such as sheet metal welding processes for electrical appliances.
