Is formed by a space as a plan view space sandwiched between the elongated outer boxes to which the elongate is attached, the long introduction passage member and the air cylinder or the forward and backward output type It is a component delivery device forming a part feeder pair, characterized in that elongate the outer box motion motor is attached is nestled in close proximity to the outer surface of the bowl in a state orthogonal.

The invention's effect

  As described above, since the parts feeder is arranged in the space defined by the introduction passage member and the outer box, the introduction passage member and the outer box are arranged in a state of being close to the outer surface of the parts feeder. And the component delivery device are arranged in a minimum space. Therefore, it becomes easy to arrange the devices in places where there are many space restrictions. Further, since the delivery part of the parts feeder is connected to the introduction passage member, the parts delivered from the parts feeder are immediately guided to the introduction passage member, thereby shortening the movement path of the parts, and the introduction passage from the delivery part. There is an effect that the component transfer to the member is surely performed.

With the previous SL parts feeder is arranged on one side of the welder body, welder component supplying device for supplying parts to a welding electrode on the other side of the main body is arranged, the delivery passage member is connected to the component supplying device Tei Ru.

  In this way, the parts feeder is arranged on one side of the welding machine main body, the parts supply device is arranged on the other side, and the parts are supplied from the parts supply device to the welding electrode. With such an arrangement, for example, the delivery passage member made of a flexible synthetic resin is arranged as short as possible and with less curvature from the component delivery device to the component supply device.

Coupled to one side of the outer box before Symbol introduction passage member and the delivery passageway member substantially parallel to, the introduction of an outer box in a fixed substrate in a stationary member passage member and the delivery passageway member that is fixed.

  Thus, since the introduction passage member and the delivery passage member are coupled to one side of the outer box in a substantially parallel state, both passage members are arranged together and are structurally compact. Since the outer box, the introduction passage member, and the delivery passage member are fixed to the substrate fixed to the stationary member, the structural parts are integrated via the substrate, and the unity of the apparatus is improved. Further, by selecting the mounting posture of the substrate, the inclined postures of the introduction passage member and the delivery passage member can be easily set.

Before Symbol introduction passage member is an attitude of the downward slope, the delivery passage member that is attached so as to be the attitude of the up-ramp.

  As described above, since the introduction passage member and the delivery passage member are coupled to one side of the outer box in a substantially parallel state, the introduction passage member may be in a downwardly inclined posture and the delivery passage member may be in an upwardly inclined posture. Easy to realize.

  Next, the best mode for carrying out a parts delivery apparatus that makes a pair with the parts feeder of the present invention will be described.

  1 to 8 show a first embodiment.

  The entire component delivery apparatus is indicated by reference numeral 100. There are various parts such as a projection nut and a projection bolt as parts handled in the apparatus 100. Here, as shown in FIG. 1B, the dome nut 1 is made of a hat and made of iron. The dome nut 1 includes a circular flange portion 2, a tapered portion 3 formed on the outer peripheral portion thereof, and a main body portion 4 connected to the tapered portion 3 and having a smaller diameter than the flange portion 2. As shown in FIG. 1F, the main body 4 has a regular hexagonal cross section. A hemispherical dome 5 is provided in a state of being continuous with the main body 4. Further, three welding projections 11 in electric resistance welding are formed on the surface of the flange portion 2 on the side opposite to the taper portion 3. And since the length of the main-body part 4 is lengthened, the center of gravity of the dome nut 1 is placed on the lower side.

  In the component delivery device 100, a long introduction passage member 7 is coupled to a lateral side portion of an elongated outer box 6 having a substantially rectangular parallelepiped shape. 1B is a cross-sectional view taken along the line B-B in FIG. 1A. As shown in FIG. 1B, the introduction passage member 7 includes two elongated plates 8 and 9 arranged in parallel. The thick plates 8 and 9 are integrated by a coupling member 10 by bolt coupling or the like. A dome nut 1 is supported in a hanging manner in the passage space therebetween. In this supported state, the tapered portion 3 is locked to the corner portion 12 on the inner surface of the thick plates 8 and 9.

  The introduction passage member 7 is coupled to the outer box 6 in a substantially perpendicular direction. That is, the longitudinal direction of the introduction passage member 7 and the longitudinal direction of the outer box 6 are substantially orthogonal to each other. In FIG. 1A, they are orthogonal. The passage space of the introduction passage member 7 communicates with an inlet hole 13 provided on the lateral side of the outer box 6 so that the dome nut 1 can enter the outer box 6. Reference numeral 14 denotes a parts feeder, and the delivery section 15 is connected to the introduction passage member 7.

  The parts feeder 14 here applies vibration to a circular bowl 16 that stores a large number of dome nuts 1, and the dome nut 1 moves along a spiral part conveyance path formed along the inner periphery of the bowl 16. Thus, it is a general type that reaches the sending unit 15. The parts feeder is of a type that vibrates the bowl 16, but instead of this, a magnet is assembled to an upright rotating disk and the parts adsorbed by the rotation of the disk are guided to the delivery passage. It can be. As described above, various types of parts feeders in the present invention can be adopted.

  In order to deliver the dome nut 1 in the outer box 6, a delivery passage member 17 is coupled to the lateral side portion of the outer box 6. The delivery passage member 17 is also coupled to the outer box 6 in a substantially orthogonal state. That is, the longitudinal direction of the delivery passage member 17 and the longitudinal direction of the outer box 6 are substantially orthogonal to each other. In FIG. 1A, they are orthogonal. Therefore, the delivery passage member 17 and the introduction passage member 7 are parallel to each other. In FIG. 1A, for ease of understanding, the outer box 6 and the cover member of the delivery passage member 17 are removed.

  The delivery passage member 17 is constituted by an acceleration passage member 18 and a supply passage member 19, which are joined by a joint pipe 20 fixed to the acceleration passage member 18 by welding or the like, as shown in FIG. ing.

  The acceleration passage member 18 is made of a hard material and has an inner surface on which the dome nut 1 can easily slide. Here, it is made of stainless steel, and its inner surface is plated with chrome (not shown). 1A is a cross-sectional view taken along the line C-C in FIG. 1A, and shows a cross-sectional shape of the acceleration passage member 18. The passage of the acceleration passage member 18 includes a widened portion 22 through which the flange portion 2 passes and a main passage portion 23 through which the main body portion 4 and the dome portion 5 pass. Instead of the stainless steel, the acceleration passage member 18 may be made of a hard synthetic resin such as polypropylene or Teflon (trade name). As shown in FIG. 1C, a lid member 24 is fixed to the acceleration passage member 18 by bolting or the like, so that the passage of the acceleration passage member 18 has a closed cross-sectional shape.

  By providing the widened portion 22 and the main passage portion 23 as described above, the passage cross-sectional shape of the acceleration passage member 18 is substantially the same as the outer shape of the dome nut 1. Is set as narrow as possible. A corner 21 is formed at the boundary between the widened portion 22 and the main passage portion 23.

  As shown in FIG. 1E, the supply passage member 19 has the same cross-sectional shape as that of the acceleration passage member 18, so that the dome nut 1 is moved from the acceleration passage member 18 to the supply passage member 19. We are making a smooth transition. The supply passage member 19 is made of a flexible urethane resin or polypropylene resin.

  The widened portion 22 and the main passage portion 23 that are passage spaces of the delivery passage member 17 communicate with the outlet hole 25 provided in the lateral side portion of the outer case 6 so that the dome nut 1 is delivered from the outer case 6. It has become.

  A transfer member 26 that moves forward and backward in the outer box 6 in a direction substantially orthogonal to the introduction passage member 7 is provided. The transfer member 26 is formed of a block-like member having a substantially rectangular parallelepiped shape, is formed with an accommodation recess 27 for receiving the dome nut 1 and slides in the outer box 6. In order to advance and retract the transfer member 26, an air cylinder 28 is fixed to the end of the outer box 6 along the longitudinal direction of the outer box 6, and its piston rod 29 is coupled to the transfer member 26. When the receiving recess 27 is aligned with the inlet hole 13, one dome nut 1 enters the outer box 6. In order to assist this entry, a permanent magnet 31 is fixed to the lateral side portion of the outer box 6. When the dome nut 1 enters the receiving recess 27 and the transfer member 26 advances to the left, the second dome nut 1 is pushed back by the slope 32 provided at the opening of the receiving recess 27. ing.

  When the transfer member 26 advances to the left by the output of the air cylinder 28 and the accommodation recess 27 matches the outlet hole 25, the dome nut 1 is sent into the delivery passage member 17 by air injection. In the air injection, an air control valve (not shown) operates when the through-hole 33 provided in the lateral side portion of the outer box 6 and the injection port 34 provided in the accommodating recess 27 portion of the transfer member 26 match. The dome nut 1 is sprayed. 2 is a cross-sectional view taken along the line (2)-(2) of FIG. 1, and FIG. As shown in FIG. 2, a lid member 35 is fixed to the outer box 6 by bolting or the like. An air hose 30 communicating with the through hole 33 is provided and connected to the air control valve.

  By the operation as described above, the dome nut 1 introduced into the housing recess 27 is moved toward the outlet hole 25 and is sent one by one to the acceleration passage member 18 by air injection. The number sent out can be two or three. For this purpose, the receiving recesses 27 having a receiving depth corresponding to a predetermined number are set.

  The length of the acceleration passage member 18 is not just a length of a joint pipe. In the passage of the accelerating passage member 18, the sliding resistance of the inner surface is small, and the gap is reduced as described above so that the dynamic pressure of the blast air is sufficiently received. The speed of the dome nut 1 is increased. Here, the diameter of the flange portion 2 of the dome nut 1 is 20 mm, and 240 mm, which is 12 times that, is the acceleration section. In other words, the length at which the dome nut 1 is in the highest speed state in the acceleration passage member 18 and becomes constant is set in advance. Although it depends on conditions such as the pressure of the blast air, the mass of the component, and the sliding resistance of the passage, the length of the acceleration passage member 18 is preferably set in the range of 8 to 15 times the diameter of the component. It is.

  In the case of a small component as in this embodiment, the length of the acceleration passage member 18 is the pressure of the blast air, the mass of the component, the conveying speed, the length of the supply passage member 19, and the internal resistance of the supply passage member 19. Although there are some variations depending on the transmission test, it has been confirmed by a delivery test that it is preferable to set the acceleration section to 5 times the part diameter or part length. Therefore, the above 12 times belong to the category more than 5 times.

  Further, although the acceleration passage member 18 is shown in a straight line, the curved posture of the supply passage member 19 having a large sliding resistance can be brought as close as possible by bending the acceleration passage member 18. That is, if the supply passage member 19 has a curved portion, the dome nut 1 comes into strong contact with the inner surface of the passage on the outer periphery side of the curve and the conveyance speed is significantly reduced, but such a problem can be avoided. . On the other hand, even if the acceleration passage member 18 is curved, the sliding resistance is small, so that even if the acceleration action is reduced, it can be kept within an allowable range.

  As shown in FIG. 1F, the regular hexagonal main body 4 is configured so that both parallel sides of the hexagon are close to the inner surfaces of the thick plates 8 and 9 and cannot rotate. The same applies to the delivery passage member 17. By doing so, the direction of the rotation direction of the dome nut 1 becomes constant in the introduction passage member 7, and the interval between the dome nuts 1 becomes constant. In addition, the direction of the rotation direction is also made constant in the delivery passage member 17, and at the same time, the gap between the dome nut 1 and the inner surface of the acceleration passage member 18 is reduced, air leakage is reduced, and speedup is improved. is there.

  The parts feeder 14 and the parts delivery device 100 in the present embodiment feed the dome nut 1 to the welding location of the electric resistance welder. For this purpose, as shown in FIG. It is attached to the welding machine main body 36 in the state. That is, the support plate 38 is fixed to the welding machine main body 36, and the parts feeder 14 and the component delivery device 100 are fixed to the support plate 38. In order to fix the component delivery device 100 to the support plate 38 which is a stationary member, an iron support column 39 is coupled to the support plate 38 in a standing state. The support column 39 is formed in an elongated shape so that elastic bending vibration can be performed.

  As shown in FIGS. 4 and 5, a flat rectangular substrate 41 made of a thick plate is fixed to a support column 39 which is a stationary member. The outer casing 6, the introduction passage member 7, and the acceleration passage member 18 of the delivery passage member 17 are fixed to the substrate 41 by bolting, welding, or the like. Then, as shown in FIG. 5, the substrate 41 is inclined such that the delivery side of the dome nut 1 is raised, whereby the introduction passage member 7 is inclined downward, and the delivery passage member 17 is upwardly inclined. It is said that the attitude.

  Next, the vibration unit will be described.

  A bracket plate 42 is fixed by welding or the like in the direction perpendicular to the substrate 41 near the end of the lower surface of the substrate 41, and the bracket plate 42 extends in the longitudinal direction of the outer box 6. This extended portion is a mounting portion 43, to which a vibration unit 44 is fixed. By providing the mounting portion 43 which is an extended portion in this way, the center line O2 of the vibration unit 44 is disposed at a location offset from the center line O1 of the substrate 41, and the offset amount is indicated by the symbol L. ing.

  As described above, since the bracket plate 42 is fixed to the lower surface near the end of the substrate 41, the outer box 6 is fixed near the end of the substrate 41, and the excitation unit 44 is disposed near the outer box 6. There is an effect that can be done. Further, since the outer box 6 is fixed in the vicinity of the end portion of the substrate 41, the long introduction passage member 7 and the acceleration passage member 18 can be fixed at the substrate portion other than the portion, and for the integration of the respective parts. Convenient.

  Various structures can be adopted as the specific structure of the excitation unit 44, but here, a combination of an electromagnet and a leaf spring is employed. As shown in FIG. 3, an iron mounting block 45 is fixed to the lateral side surface of the mounting portion 43 by bolting or the like in a state of extending to the upstream side of the introduction passage member 7. A leaf spring 46 is coupled to the end of the mounting block 45 by bolting or the like, and a support block 47 is coupled to the lower portion of the leaf spring 46 by bolting or the like. An electromagnet 50 composed of an electromagnetic coil 48 and an electromagnetic iron core 49 is attached to the support block 47. The interval between the electromagnetic iron core 49 and the mounting block 45 is set narrow.

  With such a structure, when an intermittent current is passed through the electromagnet 50, the integrated body of the electromagnet 50 and the support block 47 approaches or separates from the mounting block 45 while bending the leaf spring 46, and vibration is generated. The vibration is transmitted from the mounting block 45 to the mounting portion 43 and the bracket plate 42, the substrate 41, the outer box 6, the introduction passage member 7, and the delivery passage member 17, and the entire component delivery device 100 vibrates.

  The vibration unit 44 operates when the accommodating recess 27 of the transfer member 26 is aligned with the inlet hole 13 and the dome nut 1 is introduced into the accommodating recess 27 by sliding down the introduction passage member 7, and the parts are sent out. The apparatus 100 is vibrated. Further, when the housing recess 27 of the transfer member 26 matches the outlet hole 25 and the dome nut 1 is sent out from the housing recess 27 by air injection, the operation is stopped and the component delivery device 100 is made stationary.

  As described above, by installing the offset L between the center lines O1 and O2, vibration is input to the mounting portion 43, which is an extension of the bracket plate 42, so that the bracket plate 43 bends and vibrates. There is an effect that the vibration is reliably transmitted to the component delivery device 100. Since the support column 39 is also allowed to bend and deform, the component delivery device 100 can vibrate.

  It should be noted that an electric motor that performs forward / backward output can be employed instead of the air cylinder 28. It is also possible to replace the permanent magnet 31 with an electromagnet.

  The above-described operation can be easily performed by a generally adopted control method, and a signal is transmitted at a predetermined position of an air switching valve or an air cylinder operated by an operation signal from a control device or a sequence circuit. This can be ensured by combining sensors that emit and transmit to the control device.

  Next, the positional relationship between the parts delivery device and the parts feeder will be described.

  The above positional relationship is shown in FIGS. In addition, about the same thing as the member demonstrated in FIGS. 1-5, the same code | symbol is described in the figure, and detailed description is abbreviate | omitted.

  The welding machine performs electrical resistance welding, and the welding machine main body 36 is fixed to the floor 37 as described above. The welding machine main body 36 is a member constituting the main skeleton of the welding machine, and the support plate 38 is coupled to one side thereof in a substantially horizontal posture. The parts feeder 14 is fixed on the support plate 38. The long introduction passage member 7 and the elongated outer box 6 of the component delivery apparatus 100 are in a substantially perpendicular positional relationship, whereby the space 51 is defined by the introduction passage member 7 and the outer case 6.

  As shown in FIG. 7, the space 51 is a space formed in a plan view. The space 51 is formed as an inner space sandwiched between the introduction passage member 7 and the outer box 6. The parts feeder 14 is arranged in the space 51 thus partitioned. That is, the introduction passage member 7 and the outer box 6 are arranged in a state of being close to the outer surface of the parts feeder 16. Here, the introduction passage member 7 and the outer box 6 are in close contact with the outer surface of the bowl 16 of the parts feeder 14. That is, the introduction passage member 7 and the outer box 6 are as close as possible to the outer surface of the bowl 16 of the parts feeder 14.

  As shown in FIG. 7, a spiral part conveyance path 52 is provided on the inner periphery of the bowl 16, and the dome nut 1 is led to the outside of the bowl 16 from the terminal portion of the part conveyance path 52 and comes out of the outside. The place is the sending unit 15. The delivery portion 15 is connected to the upper end portion of the introduction passage member 7.

  As described above, the parts feeder 14 and the parts delivery device 100 are arranged on one side of the welding machine main body 36, and the welding electrodes are arranged on the opposite side of the welding machine main body 36. As shown in FIG. 8, this electrode has a pair of a fixed electrode 54 and a movable electrode 55. A support arm 56 is coupled to the welder main body 36, and a fixed electrode 54 is provided there. Further, another support arm 57 is coupled to the welder main body 36, and an air cylinder 58 is fixed thereto, and the movable electrode 55 is advanced and retracted by the air cylinder 58. A steel plate component 59 is placed on the fixed electrode 54, and the dome nut 1 is welded thereto.

  The dome nut 1 is supplied by the component supply device 60 to the steel plate component 59 at the location of the fixed electrode 54. The component supply device 60 functions to receive the dome nut 1 from the supply passage member 19 and supply the dome nut 1 to the location of the fixed electrode 54. Therefore, various types of devices can be adopted.

  Here, the dome nut 1 positioned at a predetermined location is supplied by an advancing and retracting supply rod. The guide cylinder 62 is coupled to a stationary member 63, for example, a support rod (not shown) extending from the welder main body 36. An air cylinder 64 is fixed to the end of the guide cylinder 62, and the supply rod 65 is advanced and retracted by the piston rod. A temporary fixing box 66 is fixed to the lower end portion of the guide cylinder 62, and the supply passage member 19 is connected to the temporary fixing box 66.

  When the supply rod 65 advances toward the dome nut 1 positioned in the temporary fixing box 66, the dome nut 1 is held at the tip of the supply rod 65 and supplied to the fixed electrode 54. This holding can be performed by a magnet disposed at the tip of the supply rod 65 or a vacuum.

As is apparent from FIG. 6, the delivery passage member 17 is inclined upward, and the inclination can be shortened as much as possible without causing the supply passage member 19 toward the temporary fixing box 66 to be greatly curved. If it is a downwardly inclined delivery passage member, as shown by a two-dot chain line with an arrow in FIG. 6, a large number of curves and a significantly long supply passage member 19 are required, which is uneconomical. At the same time, the carrier air must be high and the flow rate must be increased.

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

  As described above, since the parts feeder 14 is disposed in the space 51 defined by the introduction passage member 7 and the outer box 6, the introduction passage member 7 and the outer box 6 are arranged on the outer surface of the bowl 16 of the parts feeder 14. The parts feeder 14 and the parts delivery device 100 are arranged with a minimum space. Therefore, it becomes easy to arrange the devices in places where there are many space restrictions. Further, since the delivery portion 15 of the parts feeder 14 is connected to the introduction passage member 7, the dome nut 1 delivered from the parts feeder 14 is immediately guided to the introduction passage member 7, thereby moving the movement path of the dome nut 1. There is an effect that the dome nut 1 is reliably transferred from the delivery portion 15 to the introduction passage member 7.

  Since the bowl 16 is disposed above the parts feeder 14, the delivery unit 15 attached to the bowl 16 is also disposed above the parts feeder 14. By connecting the introduction passage member 7 to the delivery portion 15 having such an arrangement, the introduction passage member 7 can be inclined downward, and the dome nut 1 in the introduction passage member 7 can smoothly slide down, The dome nut is reliably introduced into the outer box 6.

  The parts feeder 14 is disposed on one side of the welder main body 36, and a parts supply device 60 for supplying the dome nut 1 to the fixed electrode 54 is disposed on the other side of the welder main body 36. The component supply device 60 is connected to a temporary fixing box 66.

  Thus, the parts feeder 14 is arranged on one side of the welding machine main body 36, and the component supply device 60 is arranged on the other side, and the dome nut 1 is supplied from the component supply device 60 to the fixed electrode 54. With such an arrangement, for example, the delivery passage member 17 made of a flexible synthetic resin is arranged as short as possible from the component delivery device 100 toward the component supply device 60 with less curvature.

  The introduction passage member 7 and the delivery passage member 17 are coupled to one side of the outer case 6 in a substantially parallel state, and the outer case 6, the introduction passage member 7, and the delivery passage are attached to the substrate 41 fixed to the support column 39 which is a stationary member. The member 17 is fixed.

  Thus, since the introduction passage member 7 and the delivery passage member 17 are coupled to one side of the outer box 6 in a substantially parallel state, both the passage members 7 and 17 are arranged together and are structurally compact. Since the outer box 6, the introduction passage member 7, and the delivery passage member 17 are fixed to the substrate 41 fixed to the stationary member, the respective structural parts are integrated through the substrate 41, and the unity as the apparatus is improved. Further, by selecting the mounting posture of the substrate 41, the inclined postures of the introduction passage member 7 and the delivery passage member 17 can be set easily.

  The introduction passage member 7 is attached so as to be inclined downward, and the delivery passage member 17 is attached so as to be inclined upward.

  As described above, since the introduction passage member 7 and the delivery passage member 17 are coupled to one side of the outer box 6 in a substantially parallel state, the introduction passage member 7 is in a downwardly inclined posture and the delivery passage member 17 is in an upwardly inclined manner. Easy to achieve posture.

  As described above, according to the present invention, the parts feeder and the parts delivery device are arranged in a minimum space, and the parts delivery paired with the parts feeder capable of fully exhibiting the functions of the parts delivery apparatus is performed. Since it is a device, it can be used in a wide range of industrial fields, such as automobile body welding processes and home appliance sheet metal welding processes.
