Description

  The present invention relates to a shaft-shaped component supply device for inserting a shaft portion and a shaft-shaped component having a head having a diameter larger than that of the shaft portion into a receiving hole which is a target location.

  Japanese Patent Laid-Open No. 10-225774 describes that a chuck mechanism holding a bolt is moved forward and backward to push and expand the chuck mechanism at the tip of the component supply pipe.

JP-A-10-225774

  Patent Document 1 describes that the bolt is surely supplied to the chuck mechanism by expanding the chuck mechanism, but the component supply passage for guiding the shaft-shaped component and the receiving hole into which the shaft-shaped component is inserted. Nothing is said about presetting the relative position of the shaft and accurately inserting it into the receiving hole in conformity with the shape of the shaft-like component.

  The present invention is provided to solve the above-described problems, and the relative position between the component supply passage for guiding the shaft-shaped component and the receiving hole, which is the target location of supply, is changed to the form of the shaft-shaped component. The purpose is to ensure that parts are supplied in a consistent manner.

The invention described in claim 1
A shaft part and a shaft-like component having a head having a diameter larger than that of the shaft part are to be supplied, and the shaft part is inserted into the receiving hole of the insertion base member, and then the insertion base member is moved. In the parts supply device of the type that positions the head at the target location,
A parts supply passage communicating with a parts supply source such as a parts feeder and a receiving hole formed in the insertion base member are arranged coaxially on the insertion axis,
The distance between the outlet opening end of the component supply passage and the inlet opening end of the receiving hole is shorter than the axial length of the head, or the outlet opening end and the inlet opening end are in close contact with each other. Axial component characterized in that it is provided with advancing / retreating drive means for advancing / retracting either the component supply passage or the receiving hole in the insertion axis direction so as to be longer than the axial length of the head during movement Supply device.

  The distance between the outlet opening end of the component supply passage and the inlet opening end of the receiving hole is shorter than the axial length of the head, or the outlet opening end and the inlet opening end are in close contact with each other. Advancing / retreating drive means is provided for advancing and retracting either the component supply passage or the receiving hole in the insertion axis direction so as to be longer than the axial length of the head during movement.

  If the distance between the outlet opening end of the component supply passage and the inlet opening end of the receiving hole is shorter than the axial length of the head, when the shaft-shaped component is transferred, the shaft of the shaft-shaped component It is simultaneously achieved that the portion enters the receiving hole and the head is held in the component supply passage. That is, since the shaft-shaped component enters both the receiving hole and the component supply passage, the head is present in the component supply passage until the shaft portion of the shaft-shaped component completely enters the receiving hole. As a result, the shaft-like component is reliably inserted into the receiving hole. That is, when the insertion of the shaft portion into the receiving hole is started, the head is always held in the component supply passage, so that the relative position of the shaft-shaped component with respect to the component supply passage and the receiving hole is correctly positioned on the insertion axis. Thus, accurate parts supply is achieved. In this way, the component supply passage and the receiving hole are arranged on the insertion axis in advance, and the distance between the outlet opening end of the component supply passage and the inlet opening end of the receiving hole is set to the above value. However, it works in a complex manner.

  If the distance between the outlet opening end of the component supply passage and the inlet opening end of the receiving hole is longer than the axial length of the head of the shaft-shaped component when the shaft-shaped component is inserted, the shaft portion becomes the receiving hole. Since the head is in a state of being released from the part supply passage at the stage where it does not completely enter, if the whole shaft-shaped part tilts with some external force, it will not be able to smoothly enter the receiving hole, The movement stability during the insertion transition period of the shaft-like component is reduced.

  On the other hand, when the interval distance between the outlet opening end of the component supply passage and the inlet opening end of the receiving hole disappears and the outlet opening end and the inlet opening end are in close contact, the interval distance is the axial direction of the head. As in the case where the length is shorter than the length, when the shaft-shaped component is transferred, the shaft portion of the shaft-shaped component enters the receiving hole, and the head is held in the component supply passage. Is achieved at the same time. That is, since the shaft-shaped component enters both the receiving hole and the component supply passage, the head is present in the component supply passage until the shaft portion of the shaft-shaped component completely enters the receiving hole. As a result, the shaft-like component is reliably inserted into the receiving hole. That is, when the insertion of the shaft portion into the receiving hole is started, the head is always held in the component supply passage, so that the relative position of the shaft-shaped component with respect to the component supply passage and the receiving hole is correctly positioned on the insertion axis. Thus, accurate parts supply is achieved. In this way, the component supply passage and the receiving hole are arranged on the insertion axis in advance, and the distance between the outlet opening end of the component supply passage and the inlet opening end of the receiving hole is set to the above value. However, it works in a complex manner.

  As described above, when the distance between the outlet opening end of the component supply passage and the inlet opening end of the receiving hole is such that the outlet opening end and the inlet opening end are in close contact, the space of the component supply passage and the reception Since the hole space is in the form of a series of continuous spaces, the guide function for the shaft-shaped component is further improved, and reliable component insertion can be achieved.

  Then, when the insertion base member is moved and the head is positioned at the target location after the insertion of the shaft-shaped component, either the component supply passage or the receiving hole is retracted in the insertion axial direction, and the outlet of the component supply passage By making the distance between the opening end and the inlet opening end of the receiving hole longer than the axial length of the head, the movement space of the head can be secured, and the insertion base member into which the axial component is inserted Movement is reliably achieved.

  In a shaft-shaped component having a shaft portion and a head having a diameter larger than that of the shaft portion, the mass of the head portion may be larger than the mass of the shaft portion. And when the height to the upper side of a head is high, it becomes a property which a shaft-shaped component tends to fall down. However, since the head is always held in the parts supply passage as described above, the parts are prevented from falling during the insertion transition period, and the normal posture can be maintained appropriately.

  The present invention is an apparatus invention as described above, but as can be clearly understood from the embodiments described below, it can exist as a method invention that specifies the behavioral state and the like of the shaft-like component.

It is sectional drawing of the whole apparatus, and the external view of a related location. It is sectional drawing which shows an insertion operation state. It is sectional drawing which shows an insertion operation state. It is sectional drawing which shows the other example of an interval distance conversion mechanism. It is a side view which shows another shaft-shaped component.

  Below, the form for implementing the supply apparatus of the shaft-shaped component which concerns on this invention is demonstrated.

  1 to 5 show an embodiment of the present invention.

  First, the shaft-like component will be described.

  There are various types of shaft-shaped parts, and an example is shown in FIG. The whole shaft-like component is denoted by reference numeral 1 and is made of iron. The shaft portion 2 is configured by an elongated member having a circular cross section, and the head portion 3 is configured by an elongated member having a circular cross section and has a diameter larger than that of the shaft portion 2. As for the dimensions of each part, the total length of the shaft-like component 1 is 60 mm, the diameter and length of the shaft part 2 are 4 mm and 34 mm, and the diameter and length of the head 3 are 12 mm and 26 mm.

  Next, the structure on the component supply passage side of the apparatus will be described.

  The entire device is indicated by reference numeral 100. A block-shaped support member 5 made of stainless steel or the like is fixed to a stationary member 4 such as a machine frame. A typical shape of this block shape is a rectangular parallelepiped. A support hole 6 in the vertical direction is formed in the center portion of the support member 5 in a state of passing through the support member 5. The support hole 6 has a circular cross-sectional shape.

  A guide tube 7 made of a tubular member having a circular cross section is inserted into the support hole 6 in a slidable state. There is no gap between the outer peripheral surface of the guide tube 7 and the inner peripheral surface of the support hole 6, so that the guide tube 7 can move forward and backward. The internal space of the guide tube 7 is a component supply passage 8.

  The guide tube 7 is advanced and retracted in the vertical direction by an advancing / retreating drive means constituted by an air cylinder, an advance / retreat output type electric motor, or the like. In this embodiment, an air cylinder 9 is used as means for performing this advance / retreat. A flange 10 is formed at the lower end of the guide tube 7, and a plate-like coupling member 12 is fixed thereto by bolting or the like. The air cylinder 9 is fixed to the side surface of the support member 5, and its piston rod 13 is coupled to the coupling member 12. The piston rod 13 advances and retreats in the vertical direction.

  A supply pipe 15 extending from the parts feeder 14 is coupled to the support member 5 by bolting or the like, and the supply pipe 15 communicates with the parts supply passage 8. The shaft-like component 1 is conveyed by jetting compressed air, and air is jetted from the jet pipe 16. In order to prevent the shaft-like component 1 from being caught, a tapered surface 17 is formed on the inner surface of the upper end of the guide tube 7.

  The flat lower surface of the flange 10 exists on a virtual horizontal plane, and this surface constitutes the outlet opening end 18 of the component supply passage 8.

  In addition, the BB cross section of FIG. 1 (A) is the (B) figure of the same figure. Similarly, the CC cross section of FIG. 1 (A) is the (C) figure of the same figure, and the DD cross section of FIG. 1 (A) is the (D) figure of the same figure.

  Next, the structure on the insertion base member side of the apparatus will be described.

  An insertion base member 20 made of a cylindrical stainless steel member is disposed below the component supply passage 8. A vertical receiving hole 21 is formed at the center of the insertion base member 20, and the shaft portion 2 is inserted therein. When the receiving hole 21 is provided for insertion of the shaft portion 2, the axis of the component supply passage 8 and the axis of the receiving hole 21 coincide with each other, and this is the insertion axis OO. In order to ensure the insertion of the shaft portion 2, a tapered hole 22 is formed in the opening portion of the receiving hole 21.

  The flat upper surface of the insertion base member 20 exists on a virtual horizontal plane, and this surface constitutes the inlet opening end 23 of the receiving hole 21.

  As the air cylinder 9 advances and retreats, the distance between the outlet opening end 18 and the inlet opening end 23 is increased or decreased as indicated by L1 shown in FIG. 2 or L2 shown in FIG.

  A moving mechanism 24 is provided to move the shaft-like component 1 inserted into the receiving hole 21 to a target location. As shown by a two-dot chain line in FIG. 1A, the moving mechanism 24 may be any mechanism that moves the head 3 to a predetermined target position, and various types such as a guide rail method and a screw shaft method are adopted. it can. Here, the former guide rail system is used.

  A stationary rail 25 is fixed in a horizontal orientation on the stationary member 4, and a movable member 26 is slidably assembled to the stationary rail 25. The movable member 26 is made of thick stainless steel, and includes a slide portion 27 assembled to the stationary rail 25 and a support surface 28 made of a flat surface, as shown in FIG. . A leg member 29 is fixed to the support surface 28 by bolting or the like, and the insertion base member 20 is fixed thereon.

  An air cylinder 30 is fixed on the stationary member 4, and its piston rod 31 is coupled to the movable member 26. The piston rod 31 is arranged in a horizontal posture in the longitudinal direction of the stationary rail 25. When the piston rod 31 extends, the movable member 26 moves and the insertion base member 20 moves to the position shown by the two-dot chain line. . This movement causes the head 3 to stand by at a position corresponding to the robot device 33 here.

  The robot device 33 is of a normal 6-axis type, holds the head 3 with a holding socket 34 arranged at the tip thereof, and transfers it to the next target location. When the robot device 33 is operated and the head 3 is relatively moved into the holding socket 34, the robot 3 is attracted by the permanent magnet 35 attached in the holding socket 34, and the shaft portion 2 is extracted from the receiving hole 21 in this state. And transferred to the next destination.

  A permanent magnet 36 is embedded in the movable member 26, and the attraction force acts on the shaft portion 2 inserted into the receiving hole 21. For this purpose, the permanent magnet 36 is arranged on the insertion axis OO. By such a suction force, the lower surface of the head 3 hits the inlet opening end 23, and the stationary position of the shaft-like component 1 is accurately maintained. Alternatively, the tapered hole 22 can be enlarged so that the lower end corner of the head 3 can be received by the tapered hole 22.

  Next, the operation of the apparatus will be described.

  First, the case of L1 in which the distance is shorter than the axial length of the head 3 will be described with reference to FIG. As shown in FIG. 2, the guide tube 7 extends downward along the insertion axis OO by the advance operation of the air cylinder 9, and the distance L <b> 1 is set to a length shorter than the axial length of the head 3. Is done. When the shaft-shaped component 1 is fed from the parts feeder 14 with the shaft portion 2 on the advanced side, the shaft portion 2 is inserted into the receiving hole 21 from the tapered hole 22. During the insertion transition period, the head 3 is held on the component supply passage 8, that is, the inner surface of the guide tube 7. That is, the head 3 enters the guide tube 7 with almost no gap, minimizing the amount of deviation of the head 3 from the insertion axis OO, and the shaft-like component 1 extends along the insertion axis OO. And smoothly and accurately inserted into the receiving hole 21.

  When the insertion of the shaft portion 2 into the receiving hole 21 is completed in this way, the shaft-like component 1 is attracted by the permanent magnet 36 and is in a stable insertion state. Thereafter, the air cylinder 9 is retracted to increase the interval distance L1, which is larger than the axial length of the head 3, that is, where the interval distance is L2 shown in FIG. The backward movement of the cylinder 9 stops.

  Next, the movable member 26 moves along the stationary rail 25 by the advancing operation of the air cylinder 30, and stops at a position that matches the holding socket 34 of the robot apparatus 33. Then, the shaft-like component 1 is extracted from the receiving hole 21 by the operation of the robot device 33 and transferred to the next target location. Since the distance L2 is larger than the axial length of the head 3, when the movable member 26 moves along the stationary rail 25, the head 3 moves in the horizontal direction without interfering with anything. be able to.

  Next, the case where the interval distance disappears and the outlet opening end and the inlet opening end are in close contact with each other will be described with reference to FIG. As shown in FIG. 3, the guide tube 7 extends downward along the insertion axis OO by the advancing operation of the air cylinder 9, the outlet opening end 18 comes into close contact with the inlet opening end 23, and the interval distance disappears. Set to state. When the shaft-shaped component 1 is fed from the parts feeder 14 with the shaft portion 2 on the advanced side, the shaft portion 2 is inserted into the receiving hole 21 from the tapered hole 22. During the insertion transition period, the head 3 is held on the component supply passage 8, that is, the inner surface of the guide tube 7. That is, the head 3 enters the guide tube 7 with almost no gap, minimizing the amount of deviation of the head 3 from the insertion axis OO, and the shaft-like component 1 extends along the insertion axis OO. And smoothly and accurately inserted into the receiving hole 21.

  When the insertion of the shaft portion 2 into the receiving hole 21 is completed in this way, the shaft-like component 1 is attracted by the permanent magnet 36 and is in a stable insertion state. Thereafter, an interval distance that disappeared by the backward movement of the air cylinder 9 was formed, and the distance became larger than the axial length of the head 3, that is, the interval distance became L2 shown in FIG. The backward movement of the air cylinder 9 stops at that point.

  Next, the movable member 26 moves along the stationary rail 25 by the advancing operation of the air cylinder 30, and stops at a position that matches the holding socket 34 of the robot apparatus 33. Then, the shaft-like component 1 is extracted from the receiving hole 21 by the operation of the robot device 33 and transferred to the next target location. Since the distance L2 is larger than the axial length of the head 3, when the movable member 26 moves along the stationary rail 25, the head 3 moves in the horizontal direction without interfering with anything. be able to.

  As described above, the distance between the outlet opening end 18 of the component supply passage 8 and the inlet opening end 23 of the receiving hole is shorter than the axial length of the head 3 or the outlet opening end 18 and the inlet opening end 23. Any one of the zero distances where the two are in close contact with each other is selected, and reliable insertion of the receiving hole of the shaft-like component 1 is achieved. Then, after the receiving hole is inserted, the interval distance becomes longer than the axial length of the head 3, and the horizontal movement of the shaft-shaped component 1 and the insertion base member 20 becomes possible.

  In the above case, the guide tube 7 is moved back and forth to set the distance to L1 or L2, or the distance is eliminated. On the other hand, in the example of FIG. 4, the air cylinder 9 is stopped, and the insertion base member 20 is advanced and retracted along the insertion axis OO to obtain a required interval distance.

  An air cylinder 37 instead of the air cylinder 9 is attached to the movable member 26, and a support plate 39 having a support surface 28 is coupled to the upper portion of the piston rod 38. A leg member 29 is fixed to the support plate 39. Other configurations are the same as those in the case of FIG. 1 including portions not shown, and members having similar functions are denoted by the same reference numerals. Then, the same operation as in the case of FIG. 1 is performed.

  Another example of the shaft-like component is a bolt 40 shown in FIG. It is composed of a hexagonal head 41, a shaft portion 42 with a male screw cut, and a circular flange 43. The circular shape of the flange 43 corresponds to the above-described head 3 having a circular cross section. The interval distances such as L1 and L2 are set according to the height dimension of the head 41 and the thickness dimension of the flange 43.

  It should be noted that an electric motor that performs forward / backward output can be employed instead of the various air cylinders. It is also possible to replace the various permanent magnets with electromagnets.

  Operations such as the forward / backward movement and air injection of each air cylinder described above can be easily performed by a generally adopted control method. A predetermined operation can be ensured by combining an air switching valve that operates with a signal from the control device or the sequence circuit, a sensor that emits a signal at a predetermined position of the air cylinder, and transmits the signal to the control device.

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

  The distance between the outlet opening end 18 of the component supply passage 8 and the inlet opening end 23 of the receiving hole 21 is shorter than the axial length of the head 3 or the outlet opening end 18 and the inlet opening end 23 are in close contact with each other. In addition, an air cylinder that advances or retracts either the component supply passage 8 or the receiving hole 21 in the direction of the insertion axis OO so that it is longer than the axial length of the head 3 when the insertion base member 20 is moved. 9. An air cylinder 37 is provided.

  When the distance between the outlet opening end 18 of the component supply passage 8 and the inlet opening end 23 of the receiving hole 21 is shorter than the axial length of the head 3, the axial component 1 is transferred. The shaft portion 2 of the shaft-like component 1 is simultaneously entered into the receiving hole 21 and the head 3 is held in the component supply passage 8 at the same time. That is, since the shaft-shaped component 1 enters both the receiving hole 21 and the component supply passage 8, the head 3 supplies the component until the shaft portion 2 of the shaft-shaped component 1 completely enters the receiving hole 21. As a result, the shaft-like component 1 is reliably inserted into the receiving hole 21. That is, when the insertion of the shaft portion into the receiving hole 21 is started, the head 3 is always held by the component supply passage 8, so that the relative position of the shaft-shaped component 1 with respect to the component supply passage 8 and the reception hole 21 is inserted. Positioned correctly on the axis OO, an accurate part supply is achieved. In this way, the component supply passage 8 and the receiving hole 21 are arranged in advance on the insertion axis OO, and the distance between the outlet opening end 18 of the component supply passage 8 and the inlet opening end 23 of the receiving hole 21 is as follows. The fact that it is set to the above value works in a complex manner.

  If the distance between the outlet opening end 18 of the component supply passage 8 and the inlet opening end 23 of the receiving hole 21 is longer than the axial length of the head 3 of the shaft-shaped component 1 when the shaft-shaped component is inserted, Since the head 3 is in a state of being released from the component supply passage 8 at a stage where the shaft portion 2 does not completely enter the receiving hole 21, if the entire shaft-shaped component 1 is inclined by some external force, the receiving hole 21 is not smoothly entered, and the movement stability of the shaft-like component 1 during the insertion transition period is lowered.

  On the other hand, when the distance between the outlet opening end 18 of the component supply passage 8 and the inlet opening end 23 of the receiving hole 21 disappears and the outlet opening end 18 and the inlet opening end 23 are in close contact with each other, the interval distance is As in the case where the axial part 1 is shorter than the axial length of the head part 3, when the axial part 1 is transferred, the axial part 2 of the axial part 1 has entered the receiving hole 21, It is simultaneously achieved that the head 3 is held in the component supply passage 8. That is, since the shaft-shaped component 1 enters both the receiving hole 21 and the component supply passage 8, the head 3 supplies the component until the shaft portion 2 of the shaft-shaped component 1 completely enters the receiving hole 21. As a result, the shaft-like component 1 is reliably inserted into the receiving hole 21. That is, when the insertion of the shaft portion into the receiving hole 21 is started, the head 3 is always held by the component supply passage 8, so that the relative position of the shaft-shaped component 1 with respect to the component supply passage 8 and the reception hole 21 is inserted. Positioned correctly on the axis OO, an accurate part supply is achieved. In this way, the component supply passage 8 and the receiving hole 21 are arranged in advance on the insertion axis OO, and the distance between the outlet opening end 18 of the component supply passage 8 and the inlet opening end 23 of the receiving hole 21 is as follows. The fact that it is set to the above value works in a complex manner.

  As described above, when the distance between the outlet opening end 18 of the component supply passage 8 and the inlet opening end 23 of the receiving hole 21 is such that the outlet opening end 18 and the inlet opening end 23 are in close contact with each other, Since the space of the supply passage 8 and the space of the receiving hole 21 are in the form of a series of continuous spaces, the guide function for the shaft-shaped component 1 is further improved, and reliable component insertion can be achieved.

  Then, after the insertion of the shaft-shaped component 1 is completed, when the insertion base member 20 is moved to position the head 3 at the target location, either the component supply passage 8 or the receiving hole 21 is retracted in the direction of the insertion axis OO. Thus, the space for moving the head 3 is ensured by making the distance between the outlet opening end 18 of the component supply passage 8 and the inlet opening end 23 of the receiving hole 21 longer than the axial length of the head 3. Thus, the movement of the insertion base member 20 into which the shaft-like component 1 is inserted is reliably achieved.

  In the shaft-shaped component 1 having the shaft portion 2 and the head portion 3 having a larger diameter than the shaft portion 2, the mass of the head portion 3 may be larger than the mass of the shaft portion 2. And when the height to the upper side of the head 3 is high, the shaft-shaped component 1 tends to fall down. However, since the head 3 is always held in the component supply passage 8 as described above, the shaft-like component 1 is prevented from falling during the insertion transition period, and a normal posture can be maintained appropriately. it can.

  A guide tube 7 having a component supply passage 8 is inserted into a support hole 6 provided in the support member 5 in a state in which the guide tube 7 can be advanced and retracted, and the guide tube 7 is advanced and retracted by an air cylinder 9 which is an advance / retreat driving means attached to the support member 5. Because of the structure, a structure for moving the component supply passage 8 forward and backward with respect to the support member 5 can be easily formed. Because of such a simple configuration, the guide tube 7 can be smoothly advanced and retracted while ensuring the coaxiality of the component supply passage 8 and the receiving hole 21 in the insertion axis OO state.

  Since the attractive force of the permanent magnet 36 acts on the shaft-like component 1 (shaft portion 2) inserted into the receiving hole 21, the integrity of the shaft-like component 1 and the insertion base member 20 is improved, and the insertion base member The support position of the shaft-shaped component 1 is not shifted during the movement of 20, and a stable component transfer is obtained.

  Since the insertion axis OO and the advancing / retreating direction of the insertion base member 20 due to the rail structure are orthogonal, the positional relationship in which the insertion direction of the shaft-like component into the receiving hole 21 and the transition direction of the insertion base member 20 are orthogonal is The movement of the shaped part 1 takes a simple form from the vertical direction to the horizontal direction. Therefore, stable component transfer can be obtained, and it is effective for simplifying the device structure.

  As described above, according to the apparatus of the present invention, the relative position between the component supply passage for guiding the shaft-shaped component and the receiving hole, which is the target location of supply, is adapted to the form of the shaft-shaped component to ensure the Supply parts. Therefore, it can be used in a wide range of industrial fields such as automobile body welding processes and home appliance sheet metal welding processes.
