Japanese Patent No. 2521557

  The supply device as described above jets air to the end face of the shaft-like component and sends it out. Since such feeding is what pushes the so-called rear part which gives a feeding output to the rear end surface of the shaft-like part when viewed in the feeding direction, the front end side of the shaft-like part is likely to swing left and right, and therefore the front end There is a problem in that the corner portion strongly contacts the inner surface of the delivery passage, and smooth component movement cannot be obtained.

  The present invention has been provided to solve the above-described problems, and an object of the present invention is to provide a supply device for a shaft-like component with a flange-like member capable of effectively performing air injection to the flange-like member.

Means to solve the problem

The invention according to claim 1 is intended to supply a shaft-shaped component having a flange-shaped member , and the flange-shaped member is formed at or near the end of the shaft-shaped component in the direction of delivery. The lower surface of the flange-shaped member is a pressure-receiving surface, an inlet passage through which the shaft-shaped component passes through the case body, and an outlet passage disposed at a predetermined distance from the inlet passage are provided, to insert the transfer member reciprocating type, forming a concave of the shaft-like component to the transfer member in a state of being open to one side, admission space that matches the inlet passage to the accommodating recess is formed, the admission space Is a passage portion arranged to position the shaft-like component that has entered the housing recess at a substantially central portion of the transfer member, and in the state where the housing recess matches the outlet passage , Exposed Air injection port for injecting air for delivery through the entry space into the pressure-receiving surface there are is open to the inner surface of the case body facing the admission space, in a state in which the accommodating recess meets the said outlet passage The shaft-like component is characterized in that the flange-like member is disposed on the outlet passage side, and a ventilation passage for introducing outside air into the housing recess is formed in the case body opposite to the outlet passage. It is a supply apparatus of the shaft-shaped component with a flange-shaped member.

The invention's effect

  When the shaft-shaped component enters the housing recess through the inlet passage of the case body, the shaft-shaped component fully enters the housing recess and the entry position is set. When the transfer member moves in this state and the accommodation recess matches the outlet passage, the air for delivery is ejected from the air ejection port. The blast air passes through the entrance space formed on the open side of the housing recess and is blown to the flange-like member, and the shaft-like component is sent out from the outlet passage.

  On the open side of the housing recess, the flange-shaped member is exposed to the entry space and is easily subjected to direct hitting by the blast air. Therefore, the jet air from the air jet port vigorously strikes the flange-like member, thereby sufficiently obtaining the power output to the shaft-like component and realizing reliable component delivery. In other words, the entry space is used as a passage space for the blast air.

  Further, by installing the flange-like member at or near the end of the shaft-like component, the flange-like member is arranged at the front or near when viewed in the delivery direction, and the jet air is flange-like. When the member is hit directly, the front part of the shaft-like part is pulled. For this reason, the swinging motion of the front end of the component at the time of delivery is minimized, it is possible to prevent the inner surface of the delivery passage from being scratched, and smooth parts can be delivered. In this way, the shaft-like component is not pushed from the rear but pulled forward, so that the swinging movement of the tip of the shaft-like component is minimized.

Before Symbol air injection port, Oh Ru and is opened to the inner surface of the case body facing the entry space.

  Since the air injection port is arranged at the above-described location, the air for delivery is accurately injected to the flange-shaped member.

In a state where front Symbol accommodating recess meets the outlet passage, the shaft-like component is a flange-like member is disposed in the outlet passage side, the vent passage and the outlet passage for introducing outside air into the housing recess to the opposite side of the case body but that has been formed.

  The delivery air is jetted forward of the shaft-like component, and the shaft-like component is pulled forward. As described above, since the blast air is directed to the front of the housing space, that is, the outlet passage side, the pressure of the space in the housing recess at the rear of the shaft-shaped component is reduced. However, since the outside air is introduced into the housing recess from the air passage, such a phenomenon of lowering the atmospheric pressure is avoided. As a result, it is possible to prevent a decrease in the output power of the shaft-like component and to strongly send the component, and to reduce the amount of air from the air injection port, which is economical.

Is pre Symbol bottom member for reinforcing the end portion of the housing recess is formed, that has vent openings are provided in communication with the air passage in the bottom member.

  Providing the receiving recess in the transfer member reduces the rigidity of the intermediate portion of the transfer member, but providing the bottom member eliminates such a problem in rigidity. By providing the ventilation opening, outside air is introduced when the shaft-shaped component advances, and the above-described phenomenon of pressure drop is avoided.

  In the above description, the expression “front” means the direction in which the shaft-shaped component is delivered. The same applies to the following description.

  Next, the best mode for carrying out the apparatus for supplying a shaft-like component with a flange-like member of the present invention will be described.

  1 to 8 show a first embodiment.

  First, the shaft-like component handled in the present invention will be described.

  There are various types of shaft-like parts such as an elongated member having a circular or square cross section or an elongated member having a hollow cross section. The shaft-like component 1 shown in FIG. 8A is a tube having a circular cross section, and a circular flange-like member 3 is formed at the end of the cylindrical portion 2. The lower surface of the flange-shaped member 3 is a pressure receiving surface 4. The shaft-shaped component 1 shown in FIG. 2B is a flange-shaped member 3 arranged in the vicinity of the end of the cylindrical portion 2, and the other side has a bottomed shape. Is made of iron.

  In the first embodiment, the shaft-like component 1 shown in FIG. 8A is a supply target. The dimensions of each part of the same part are 43 mm in length, 14 mm in diameter of the cylindrical part 2, 20 mm in diameter of the flange-shaped member 3, 3 mm in thickness of the cylindrical part 2, 8 mm in inner diameter of the cylindrical part 2, Is 70 grams.

  A box-shaped case body 5 having an outer appearance in the shape of a rectangular parallelepiped is constituted by a box part 6 whose upper part is opened and a lid member 7 for sealing the box part 6. The lid member 7 is made of a stainless steel plate. In FIG. 1, the lid member 7 is not shown in order to facilitate understanding of the internal structure. The lid member 7 is fixed to the box portion 6 with bolts. Reference numeral 8 in FIG. 1 indicates a screw hole of the bolt.

  An inlet passage 9 through which the shaft-like component 1 passes is provided in the box portion 6 of the case body 5, and a supply rail 10 continuous thereto is joined to the side surface of the box portion 6. The supply rail 10 is U-shaped with a cross section opened upward, and the lower surface of the flange-shaped member 3, that is, the pressure receiving surface 4 on the parallel sliding surface 11, as shown by a two-dot chain line in FIG. It is designed to slide in a neck hanging shape. The inlet passage 9 is constituted by a widened portion 12 through which the flange-shaped member 3 passes and a narrow-width portion 13 through which the cylindrical portion 2 passes.

  A transfer member 14 that is advanced and retracted in a sliding state is inserted into the case body 5. As apparent from FIG. 5, the transfer member 14 is formed in a substantially rectangular parallelepiped stainless steel material with an accommodation recess 15 opened to one side. The housing recess 15 is formed with an arc portion 16 (see FIG. 5) that matches the cylindrical portion 2 at the back, and an entry space 17 is formed on the open side. The entry space 17 is a part of a space that forms the housing recess 15, and functions as a passage portion that is disposed to position the cylindrical portion 2 at a substantially central portion of the transfer member 14. Alternatively, it functions as a passage for allowing the shaft-like component 1 to reach the arc portion 16. When the transfer member 14 moves and the receiving recess 15 matches the inlet passage 9, the shaft-like component 1 is introduced into the receiving recess 15. A support step 18 that is continuous with the widened portion 12 is formed in the upper portion of the housing recess 15.

  In order to draw the shaft-shaped component 1 into the housing recess 15, a permanent magnet 19 is embedded in the vertical wall member of the box portion 6. Further, as shown in FIG. 2, a permanent magnet 20 is embedded in the lid member 7 to assist the introduction of the shaft-like component 1. The shaft-like component 1 is drawn into the housing recess 15 while the pressure receiving surface 4 slides on the sliding surface 11, but in order to reduce friction with the support step portion 18, attraction of the permanent magnet 20 is used. Yes. Therefore, in a state where the shaft-like component 1 is in the receiving recess 15, the pressure receiving surface 4 is levitated from the support step 18 as shown in FIG. 2. Actually, by tilting the posture in the state of FIG. 2 so that the right side becomes higher, the shaft-like component 1 smoothly slides into the housing recess 15 and enters. By doing so, the permanent magnet 19 can be removed.

  Since the accommodating recess 15 is formed in the transfer member 14, the bending rigidity of the entire transfer member 14 may be insufficient. For this purpose, a reinforcing bottom member 22 is provided at the lower end of the housing recess 15. The bottom member 22 is provided with a ventilation opening 23. A plurality of ventilation openings 23 are arranged on a virtual circle. And they are made to oppose the thick part of the cylindrical part 2, as shown in FIG.4 and FIG.6.

  The shaft-shaped component 1 is delivered from a circular hole-shaped outlet passage 24 provided in the lid member 7. A supply hose 25 communicating with the outlet passage 24 extends toward a target location such as an electric resistance welding electrode. In this way, the outlet passage 24 is disposed at a position away from the inlet passage 9 by a predetermined distance. This predetermined distance corresponds to the distance of the advance / retreat stroke of the transfer member 14.

  An air cylinder 27 is attached to the end of the box portion 6, and its piston rod 28 is coupled to the transfer member 14. The accommodating recess 15 of the transfer member 14 reciprocates between the inlet passage 9 and the outlet passage 24 by the operation of the air cylinder 27. In addition, the exit channel | path 24 is virtually shown by the circular line shown with the dashed-two dotted line of FIG.

  The air passage 26 is formed in a circular hole so that the outside air can be introduced into the housing recess 15 at a position where the transfer member 14 moves and the housing recess 15 matches the outlet passage 24. The ventilation path 26 communicates with the ventilation opening 23. In addition, when there is no concern about bending rigidity as described above, the bottom member 22 can be stopped. Therefore, the air passage 26 functions to introduce outside air into the housing recess 15 in the present invention.

  As shown in FIG. 5, a slope 29 is provided by scraping a part of the lateral surface of the transfer member 14. The inclined surface 29 is provided in a state of being connected to the opening of the housing recess 15, and serves to avoid interference with the shaft-shaped component 1 that waits second when the transfer member 14 advances. Yes. Moreover, the cover 30 is welded to the lid member 7 to prevent the shaft-like component 1 trying to enter the inlet passage 9 from jumping up for some reason.

  In a state in which the receiving recess 15 is aligned with the outlet passage 24, the shaft-like component 1 has the flange-like member 3 disposed on the outlet passage 24 side, and the receiving recess 15 in the case body 5 on the opposite side of the outlet passage 24. An air passage 26 for introducing outside air is formed.

The case body 5 is provided with an air injection port 32 for injecting air for delivery to the flange-shaped member 3 through the entry space 17 in a state where the accommodating recess 15 is aligned with the outlet passage 24. An air passage 33 is opened in the vertical wall member of the box portion 6, and the opening is an air injection port 32. In this way, the air injection port 32 opens on the inner surface of the case body 5 facing the entry space 17. The jet air from the air jet port 32 strikes the pressure receiving surface 4 directly through the entrance space 17. In order to perform this direct hit, the air passage 33 is inclined to aim at the pressure receiving surface 4. An air hose 34 is connected to the air passage 33 to supply blast air from a compressed air source (not shown). The air passage 33 is a circular passage having an inner diameter of 5 mm. The air pressure of the jet air is 4 Kgf / cm ² .

  Next, the operation of this apparatus will be described.

  When the shaft-like component 1 that has moved on the supply rail 10 due to inclination or transfer vibration enters the accommodating recess 15 from the inlet passage 9, it is drawn by the attractive force of the permanent magnet 19, and the cylindrical portion 2 comes into close contact with the arc portion 16. . At the same time, the flange-shaped member 3 is pulled up by the permanent magnet 20 of the lid member 7 and is in close contact with the inner surface of the lid member 7. In this state, the lower end surface of the cylindrical portion 2 slightly floats from the surface of the bottom member 22. In this state, the transfer member 14 is moved by the air cylinder 27, and the accommodation recess 15 matches the outlet passage 24. At the same time, the flange-shaped member 3 is also coaxial with the outlet passage 24. When the shaft-shaped component 1 moves to this position, the attractive force of the permanent magnet 20 does not act, so that the pressure-receiving surface 4 of the shaft-shaped component 1 is seated on the support step 18 as shown in FIG.

  Next, when the compressed air for delivery is injected from the air injection port 32, the injected air flows vigorously through the entry space 17 and directly strikes the pressure receiving surface 4. When air pressure acts on the pressure receiving surface 4, thrust in the axial direction acts on the shaft-like component 1 and is sent out from the outlet passage 24. Since the pressure receiving surface 4 is exposed to the entry space 17, a reliable pressure reception is performed. Since the flange-shaped member 3 is located in front of the shaft-shaped component 1, the shaft-shaped component 1 is delivered in a state where the front portion is pulled.

  When the shaft-shaped component 1 exits from the housing recess 15, the air pressure behind the shaft-shaped component 1 decreases. With this decrease, outside air is introduced into the housing recess 15 from the air passage 26 and the vent opening 23. The

  The example shown in FIG. 7 is a case where the lower end surface of the cylindrical portion 2 is received by the surface of the bottom member 22. In this state, the pressure receiving surface 4 floats from the support step portion 18.

  As shown in FIGS. 4 and 6, since the end face of the thick portion of the cylindrical portion 2 is opposed to the ventilation opening 23, the effect that the outside air is reliably sucked when the cylindrical portion 2 rises rapidly is obtained. is there.

  In place of the air cylinder 27 described above, an electric motor that outputs and retreats can be employed. It is also possible to replace the various permanent magnets with electromagnets or air suction.

  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.

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

  When the shaft-like component 1 enters the receiving recess 15 through the inlet passage 9 of the case body 5, the shaft-like component 1 enters the back of the receiving recess 15 and the entry position is set. In this state, when the transfer member 14 moves and the accommodation recess 15 matches the outlet passage 24, air for delivery is ejected from the air ejection port 32. The blast air passes through the entry space 17 formed on the open side of the housing recess 15 and is blown to the pressure receiving surface 4 of the flange-shaped member 3, so that the shaft-shaped component 1 is sent out from the outlet passage 24.

  On the open side of the housing recess 15, the flange-like member 3 is in a state exposed to the entry space 17, and is in a state of being easily subjected to a direct blow of the blast air. Therefore, the air jetted from the air injection port 32 vigorously hits the flange-shaped member 3, thereby sufficiently obtaining the power output to the shaft-shaped component 1 and realizing reliable component delivery. In other words, the approach space 17 is used as a passage space for the blast air.

  Further, by installing the flange-like member 3 at or near the end of the shaft-like component 1, the flange-like member 3 is arranged at the front or near when viewed in the delivery direction, and the jet air When hitting the flange-shaped member 3 directly, the front part of the shaft-shaped part 1 is pulled. For this reason, the swinging movement of the front end of the component at the time of delivery is minimized, and it is possible to prevent the outlet passage 24 and the inner surface of the supply hose 25 from coming into contact with each other, thereby enabling smooth delivery of the component. As described above, the shaft-shaped component 1 is not pushed from the rear but pulled forward, so that the swinging movement of the tip of the shaft-shaped component 1 is minimized.

  The air injection port 32 is opened on the inner surface of the case body 5 facing the entry space 17.

  Since the air injection port 32 is disposed at the above-described location, the air for delivery is accurately injected to the flange-shaped member 3.

  In a state in which the receiving recess 15 is aligned with the outlet passage 24, the shaft-like component 1 has the flange-like member 3 disposed on the outlet passage 24 side, and the receiving recess 15 in the case body 5 on the opposite side of the outlet passage 24. An air passage 26 for introducing outside air is formed.

  The delivery air is jetted in front of the shaft-shaped component 1, and the shaft-shaped component 1 is pulled forward. Thus, since the blast air is directed to the front of the housing space 15, that is, toward the outlet passage 24, the air pressure in the space of the housing recess 15 at the rear of the shaft-like component 1 is reduced. However, since the outside air is introduced into the housing recess 15 from the air passage 26, such a phenomenon of lowering the atmospheric pressure is avoided. Accordingly, it is possible to prevent a decrease in the feed output of the shaft-like component 1 and to strongly send the component, and to reduce the amount of air from the air injection port 32, which is economical.

  A reinforcing bottom member 22 is formed at the end of the housing recess 15, and a vent opening 23 communicating with the vent path 26 is provided in the bottom member 22.

  Providing the accommodating recess 15 in the transfer member 14 lowers the rigidity of the intermediate portion of the transfer member 14, but providing the bottom member 22 eliminates such a problem in rigidity. By providing the ventilation opening 23, the outside air is introduced when the shaft-shaped component advances, and the above-described phenomenon of pressure drop is avoided.

  As described above, according to the present invention, since it is a supply device capable of effectively injecting air to the flange-like member, a wide industrial field such as a car body welding process of an automobile and a sheet metal welding process of a home appliance. Available at.
