Description

The present invention relates to a component supply device that supplies components.

Parts feeders are used to transfer and supply parts such as screws and rings. The inventor of the present application has previously developed the parts feeder shown in FIG. 19 (see Patent Document 1). This parts feeder includes an inner disk 91, an outer ring plate 92 arranged on the outside of the inner disk 91 in an inclined posture with respect to the inner disk 91, and a drive mechanism for rotating the outer ring plate 92 and the inner disk 91. It is equipped with 93. The outer ring plate 92 is arranged on the same plane as the inner disk 91, and the supply portion 95 to which the part PT is supplied from the inner disk 91 and the ascending / falling portion 96 arranged at a position higher than the inner disk 91. And, the part PT supplied from the inner disk 91 is transferred from the supply unit 95 to the ascending / falling unit 96. As a result, the part PT can be discharged while reducing the noise level while extremely reducing the damage during the transfer.

The drive mechanism 93 is a common reduction motor 99, and rotates the outer ring plate 92 together with the inner disk 91. In order for the reduction motor 99 to rotate the inner disk 91 and the outer ring plate 92 together, the inner disk 91 fixes a drive pin 98 projecting to the lower surface. A pair of parallel pins 97 that guide the drive pin 98 are fixed to the outer ring plate 92. The parallel pin 97 is fixed toward the center on the upper surface of the disk 94 fixed to the outer ring plate 92. The drive pin 98 is inserted between the parallel pins 97 so that the drive pin 98 can be moved in and out and can be moved along the parallel pin 97. In the drive mechanism 93, the reduction motor 99 rotates the drive pin 98, and the drive pin 98 rotates the outer ring plate 92 via the parallel pin 97. Since the rotation centers of the inner disk 91 and the outer ring plate 92 are inclined to each other, the drive pin 98 rotates the outer ring plate 92 while sliding between the parallel pins 97.

In this way, the common reduction motor 99 rotates the inner disk 91 and the outer ring plate 92, which are two rotating bodies with different rotation axes, so that the parallel pin 97 and the drive pin 98, which are joints connecting them, are orthogonal to each other. They are connected in a state where a gap is formed so that they can be tilted diagonally from the posture of the motor.

However, due to the existence of this gap, as a result of repeating the operation of the parallel pin and the drive pin coming into contact with each other and separating from each other, there is a problem that impact or friction at the time of contact is applied to the pin. That is, when the columnar pins are crossed with each other and brought into contact with each other, the contact becomes a point shape instead of a linear shape, and stress tends to be concentrated. Further, there is a problem that the contact portion generates heat due to friction and is consumed by sliding in a state of contacting in a dot shape. Furthermore, when the rotary motion is intermittent, the impact at the time of stopping or re-driving becomes large. As a result of applying such an impact force to the pin, the pin may be damaged. In particular, when the pin is made of metal, if the metal is worn by collision or friction and metal powder is generated, the working environment is deteriorated, and if the generated metal powder adheres to the parts, there is an adverse effect that leads to deterioration of quality. ..

In order to prevent the above-mentioned wear due to the contact between the pins, a lubricant such as grease is applied to the contact portion between the pins. However, if the grease applied to this portion is scraped off by wear between the pins and disappears over time due to heat generated by friction, it becomes impossible to sufficiently prevent the wear between the metal pins. In general, grease, which is a lubricant, is not eliminated in a short time, but it is eliminated over time, which causes the above-mentioned adverse effects.

The present invention has been made in view of such a background, and one of the purposes thereof is to provide a component supply device capable of maintaining an environment in which a contact portion between pins is covered with grease for a long period of time. It is in.

Therefore, the contact interface between the first pin and the second pin can be protected with grease for a long period of time, and a situation in which breakage or wear occurs when the rotational force is transmitted can be effectively avoided.

According to the parts supply device according to the fourth aspect of the present invention, it is a parts supply device for transferring parts, and is a first rotating body rotatably arranged in a first plane about a first rotation axis.

A second rotating body rotatably arranged in a second plane inclined with respect to the first plane and either the first rotating body or the second rotating body are rotated around the two rotation axes. By rotating either the first rotating body or the second rotating body with the rotation driving mechanism for the purpose, the rotational movement is caused by either the first rotating body or the second rotating body. It is equipped with a rotation transmission mechanism for transmitting to and rotating it. The rotation transmission mechanism projects on the side of the first rotating body facing the second rotating body along the circumferential orbit centered on the first rotating axis in parallel with the first rotating axis. A pair of first pins fixed in a posture and a second pin fixed to the second rotating body in a posture toward the second rotation axis so as to be guided between the pair of first pins. The first rotating body and the second rotating body are interlocked with each other and rotate at the same time via the first pin and the second pin connected to each other, and further, the pair of first rotating bodies are rotated at the same time. The contact region between the pin and the second pin is coated with grease, and the second pin is above the contact portion with the pair of first pins and is located on the upper surface region facing the pair of first pins. It has a storage area for storing grease.

With the above configuration, the operation of the rotation transmission mechanism can be maintained for a long period of time while reducing the possibility that the pair of first pins and the second pins constituting the rotation transmission mechanism are worn or damaged due to collision or friction. In particular, according to the above component supply device, grease is applied to the contact area between the pair of first pins and the second pin, and the second pin is above the contact portion with the pair of first pins and is paired. Since the upper surface area facing the first pin is provided with a storage portion for storing grease, it is possible to effectively prevent the grease supplied to the contact area between the first pin and the second pin from being reduced over time. , Wear and damage in the contact area between the first pin and the second pin can be suppressed for a long period of time.

The second rotating body forms a second opening corresponding to the first sub-rotating plate on the bottom surface of the first opening, and the pair of first pins is formed on the bottom surface of the first sub-rotating plate. Of the above, the second pin is fixed to the outer peripheral side so that the second pin protrudes toward the second opening so that at least the tip portion of the second pin overlaps the first rotating body in a plan view. It is extended so that the distance between the pair of first pins is larger than the diameter of the second pins. With the above configuration, the first pin and the second pin of the component supply device that rotates the first rotating body and the second rotating body by the common rotation driving mechanism can be reliably interlocked and the rotation can be transmitted.

Further, according to the component supply device according to the sixth side surface, in addition to the above configuration, the storage portion is a recess formed along the extension direction of the second pin, and both sides of the second pin. It is formed in the upper corner of the. With the above configuration, by storing the grease in the recessed storage portion formed along the extension direction of the second pin, the grease can be reliably supplied to the entire contact region between the first pin and the second pin. Therefore, the contact interface between the first pin and the second pin can be protected with grease for a long period of time, and a situation in which breakage or wear occurs when the rotational force is transmitted can be effectively avoided.

(Embodiment 1)
The parts supply device according to the embodiment of the present invention are shown in FIGS. 1 to 4. In these figures, FIG. 1 is a plan view of the parts supply device, FIG. 2 is a vertical sectional view of the parts supply device of FIG. 1, and FIG. 3 is a partially enlarged horizontal cross section of the parts supply device of FIG. FIG. 4 shows an enlarged cross-sectional view showing a state in which the first pin and the second pin are moved to the positions of FIG. 3 in FIG. 2, respectively.

The parts supply device 100 shown in these figures is a device for aligning and carrying out parts P to be supplied, for example, parts such as screws, rings, pins, and ICs from a state in which they are thrown apart. Here, the flanged ring will be described as an example, but the present invention does not limit the supply object to a disc-shaped component such as a flanged ring, for example, a capsule shape, a rod shape, a columnar shape, a prismatic shape, or a conical shape. , It can be applied to a part having a polygonal cone-shaped outer shape, or it can be applied to a hollow part such as a cylinder or a square cylinder. In addition, not only parts whose front and back sides are the same or symmetrical, but also parts having asymmetry and directionality, for example, directional parts whose direction is specified by an outer peripheral protrusion such as a bearing with a brim, or a brim-shaped part. It can be applied to parts that need to be aligned by specifying their orientation and orientation, such as screws with screw heads and cylindrical screw portions, or semiconductor chips with a defined mounting surface.

The parts supply device 100 shown in FIGS. 1 and 2 is larger than the first rotating body 10 and the first rotating body 10 rotatably arranged in the first plane 12 around the first rotating shaft 11. The first opening 23 is formed in the center so that the first rotating body 10 is exposed from the first opening 23, and the first rotating shaft 21 is centered on the second rotating shaft 21 inclined from the first rotating shaft 11. Rotation drive mechanism 3 for rotating either the second rotating body 20 and the first rotating body 10 or the second rotating body 20 rotatably arranged in the second plane 22 inclined with respect to the plane 12. By rotating either the first rotating body 10 or the second rotating body 20 with the rotation driving mechanism 3, the rotational motion is transmitted to either the first rotating body 10 or the second rotating body 20. It is provided with a rotation transmission mechanism 4 for rotating this.

(First rotating body 10, second rotating body 20)
The first rotating body 10 is rotatably arranged in the first plane 12 around the first rotating shaft 11. Further, the second rotating body 20 is arranged outside the first rotating body 10. The second rotating body 20 is a second plane inclined with respect to the first plane 12 with respect to the second rotating shaft 21 inclined from the first rotating shaft 11 as shown by the alternate long and short dash line in the cross-sectional view of FIG. It is rotatably arranged within 22. The first rotating body 10 receives the supply of the component P from an externally connected device (not shown) such as a hopper, sends the component P to the second rotating body 20, and sends the component P in the aligned posture from the second rotating body 20. Discharge. The upper surface of the first rotating body 10 is a mounting surface 10A for storing the component P, and the upper surface of the second rotating body 20 is a transfer surface 20A for transferring the component P.

The structure in which the second rotating body 20 is arranged outside the first rotating body 10 is such that a large number of parts P supplied from externally connected devices are temporarily stored on the mounting surface 10A which is the upper surface of the first rotating body 10. The component P can be supplied from the first rotating body 10 to the transfer surface 20A which is the upper surface of the two rotating bodies 20. Therefore, it is possible to prevent a large number of parts P supplied to the apparatus from being supplied to the second rotating body 20 at a time, and to prevent the amount of parts P supplied to the second rotating body 20 from being reduced. Therefore, an appropriate amount of the component P can be efficiently supplied to the second rotating body 20. In particular, according to this structure, it is possible to suppress the supply of a large number of parts P to the second rotating body 20 in a state of being agglomerated, so that it is possible to effectively prevent the parts P from rubbing against each other and being damaged.

The second rotating body 20 is arranged in an inclined posture with respect to the first rotating body 10. Further, the second rotating body 20 is arranged so that a part thereof is connected to the first rotating body 10 so that the component P is supplied from the first rotating body 10. The second rotating body 20 includes a supply unit 5 to which the component P is supplied from the first rotating body 10 and an ascending unit 6 arranged at a higher position than the first rotating body 10. The component P supplied from the body 10 is transferred from the supply unit 5 to the ascending unit 6. The second rotating body 20 is arranged so as to be inclined relative to the first rotating body 10. In order to realize this configuration, in the example shown in FIG. 2, both the first rotating body 10 and the second rotating body 20 are inclined in opposite directions with respect to the horizontal plane. However, only the second rotating body may be tilted with the first rotating body in the horizontal posture, or the first rotating body may be tilted with the second rotating body in the horizontal posture.

As shown in FIG. 2, in a structure in which both the first rotating body 10 and the second rotating body 20 are inclined in the opposite directions with respect to the horizontal plane, the second rotating body 20 is moved from the supply portion 5 of the component P to the ascending portion 6. The first rotating body 10 is inclined downward from the supply portion 5 toward the ascending portion 6 of the second rotating body 6. In this structure, the inclination angle of the first rotating body 10 and the second rotating body 20 can be reduced, and the head between the second rotating body 20 and the first rotating body 10 in the ascending portion 6 can be increased. Although not shown, in the structure in which only the second rotating body is tilted, the first rotating body is arranged in a horizontal plane, and the second rotating body is tilted upward from the supply portion toward the ascending portion, and the ascending portion is used. A head is provided between the second rotating body and the first rotating body. Further, in the transfer mechanism in which the second rotating body is arranged horizontally, the first rotating body is inclined downward from the supply part toward the rising part of the second rotating body, and the second rotating body and the second rotating body are arranged at the rising part. Provide a head with one rotating body.

A part of the first rotating body 10 and the second rotating body 20 that are inclined to each other is arranged on the same surface as a supply unit 5 that supplies the component P from the first rotating body 10 to the second rotating body 20. The difference between the first rotating body 10 and the second rotating body 20 increases as the distance from the supply unit 5 increases, and the portion where the vertical difference is the largest or its vicinity is designated as the ascending unit 6. A gap is formed between the inner peripheral edge of the second rotating body 20 and the outer peripheral edge of the first rotating body 10. This is because the second rotating body 20 is tilted with respect to the first rotating body 10. The component supply device 100 shown in FIG. 2 closes the gap between the first rotating body 10 and the second rotating body 20 with a closing wall 27 so that the component P does not leak from this gap. The closing wall 27 is fixed along the first opening 23 opened in the second rotating body 20 so as to rotate together with the second rotating body 20.

The second rotating body 20 has a circular first opening 23 opened at the center, and the first opening 23 has the same size as the first rotating body 10. Further, the first rotating body 10 is arranged so as to be exposed from the first opening 23 of the second rotating body 20. In the example of FIG. 2, in the inside of the first opening 23 of the second rotating body 20, the edge of the first rotating body 10 coincides with the inner circumference of the second rotating body 20 in a cross-sectional view. It is arranged as such and is used as the supply unit 5 of the component P. With such an arrangement, the upper surface of the first rotating body 10 and the upper surface of the second rotating body 20 are partially continuous, and the component P supplied to the upper surface of the first rotating body 10 is pushed out by the supply 31. Therefore, it can be configured to be guided to the upper surface of the second rotating body 20. In particular, as shown in the cross-sectional view of FIG. 2, at the portion guided from the first rotating body 10 to the second rotating body 20, the second rotating body 20 is inclined downward toward the outer peripheral side, so that the second rotating body 20 is tilted downward. The component P transferred from the one rotating body 10 side to the second rotating body 20 side can be easily attracted to the second rotating body 20 by the weight of the component P.

The upper surface of the second rotating body 20 is a ring-shaped transfer surface 20A continuous in the transfer direction of the component P. The transfer surface 20A formed on the second rotating body 20 is formed in a ring shape along the periphery of the first rotating body 10 to transfer the component P supplied from the first rotating body 10. The rotating second rotating body 20 transfers the component P to a circular orbit. Therefore, the transfer surface 20A is provided so as to be continuous with a circular orbit centered on the second rotation shaft 21 which is the rotation center of the second rotating body 20. The transfer surface 20A of the second rotating body 20 shown in the figure is flat. However, in the parts supply device, the shape of the transfer surface 20A of the second rotating body may be U-shaped, V-shaped, or U-shaped in cross section, depending on the shape and characteristics of the parts to be transferred. ..

The first rotating body 10 and the second rotating body 20 can be manufactured by cutting one metal plate into a circle with a laser or a press. This is because the outer peripheral edge of the first rotating body 10 approaches the inner peripheral edge of the second rotating body 20. However, it goes without saying that the first rotating body 10 and the second rotating body 20 can be manufactured from different metal plates. The first rotating body 10 has, for example, an outer diameter of 10 to 80 cm so that a large number of supplied parts P can be stored. When the first rotating body 10 is enlarged, a large number of large parts P can be stored. The second rotating body 20 is designed so that the width of the transfer surface 20A is sufficiently wider than the outer diameter of the component P so that the component P can be placed and transferred on the second rotating body 20. The width of the transfer surface 20A of the second rotating body 20 varies depending on the outer diameter of the component P to be transferred and the number of rows of the component P to be transferred. For example, a circular collar having an outer diameter of 10 to 30 mm. In a device for arranging and transferring parts P, which are attachment rings, in a row, the length is 3 to 15 cm.

The first rotating body 10 and the second rotating body 20 are connected to the frame 50 so as to be rotatable. A central rod 13 centered on the first rotating body 10 is fixed to the center of the first rotating body 10, and the central rod 13 is connected to the frame 50 via a bearing so as to be rotatable. The second rotating body 20 has a second sub-rotating plate 25 fixed to the lower surface via a closing wall 27, and a cylindrical rotating shaft 28 fixed to the central portion of the second sub-rotating plate 25 is used as a bearing. It is connected to the frame 50 so as to be rotatable via the frame 50. The second rotating body 20 and the first rotating body 10 are connected to the frame 50 so that they can rotate in an inclined posture. Therefore, the rotation centers of the second rotating body 20 and the first rotating body 10 are relatively inclined.

(Rotation drive mechanism 3)
The rotation drive mechanism 3 rotates either the first rotating body 10 or the second rotating body 20. Then, as shown in the horizontal sectional view of FIG. 3, the rotation drive mechanism 3 rotates either the first rotating body 10 or the second rotating body 20, and the torque of this rotation is transmitted via the rotation transmission mechanism 4. It is configured to transmit to either the first rotating body 10 or the second rotating body 20 and rotate it. The rotation drive mechanism 3 rotates either the first rotating body 10 or the second rotating body 20, and the torque of this rotation is transmitted to either the first rotating body 10 or the second rotating body 20 via the rotation transmission mechanism 4. By rotating the other, the first rotating body 10 and the second rotating body 20 are rotated together at the same number of rotations. In the examples of FIGS. 1 and 2, the rotation drive mechanism 3 is composed of a motor 9. The motor 9 is connected to a central rod 13 fixed to the center of the first rotating body 10, and rotates the first rotating body 10 in the direction indicated by the arrow in FIG. As such a motor 9, an induction motor can be used, or a reduction motor or a stepping motor may be used.

In the component supply device 100 of FIG. 2, one motor 9 rotates the second rotating body 20 together with the first rotating body 10. In order for the motor 9 to rotate the first rotating body 10 and the second rotating body 20 together, the first rotating body 10 and the second rotating body 20 are connected via a rotation transmission mechanism 4. As such a rotation transmission mechanism 4, as shown in FIGS. 2 and 3, the first rotating body 10 fixes the first pin 14 projecting to the lower surface in parallel with the first rotating shaft 11. A pair of second pins 24 for guiding the first pin 14 are fixed to the second rotating body 20. The pair of second pins 24 are in a posture parallel to each other and are fixed toward the center on the upper surface of the second sub-rotating plate 25 fixed to the second rotating body 20. The first pin 14 is inserted between the pair of second pins 24 so that the first pin 14 can be moved in and out and can be moved along the second pin 24. In the rotation transmission mechanism 4, the first pin 14, which is driven by the motor 9 and rotates along a circular orbit centered on the first rotation shaft 11, rotates the second rotating body 20 via the second pin 24. .. Since the rotation centers of the first rotating body 10 and the second rotating body 20 are inclined to each other, the first pin 14 rotates the second rotating body 20 while sliding between the second pins 24.

The first pin 14 provided at one location of the first rotating body 10 and the second pin 24 provided at one location of the second rotating body 20 are located at the positions P1, P2, and P3 in the enlarged view of FIG. An enlarged cross-sectional view at a certain time is shown in FIG. In this way, the first pin 14 and the second pin 24 constituting the rotation transmission mechanism 4 have rotation axes that are inclined to each other, but by sliding each other at the contact interface, one rotation is changed to the other rotation. Can be communicated to.

The component supply device 100 shown in FIG. 2 has a structure in which the motor 9 which is the rotation drive mechanism 3 rotates the first rotating body 10. In the component supply device 100, the motor 9 rotates the first rotating body 10 and transmits the torque of this rotation to the second rotating body 20 via the rotation transmission mechanism 4 to rotate the second rotating body 20. In this case, by directly connecting the drive shaft of the motor 9 to the center rod 13 of the first rotating body 10, the first rotating body 10 can be rotated at a predetermined rotation speed. Since the component supply device 100 directly rotates the central rod 13 of the first rotating body 10 by the motor 9 which is the rotation driving mechanism 4 and rotates the second rotating body 20 via the rotation transmission mechanism 4, the second rotating body 20 is rotated. It does not require a transmission mechanism such as a gear mechanism for rotating the one-rotating body 10 or the second rotating body 20. Therefore, the second rotating body 20 can be rotationally driven as a simple structure in which the rotating shaft 28 connected to the second rotating body 20 is fixed to the frame 50 via the bearing. Further, since the first rotating body 10 is directly driven by the motor 9, the first rotating body 10 on which a large number of parts P are loaded and becomes heavy can be stably rotated. In particular, since the first rotating body 10 to which a large number of parts are supplied and becomes heavy is directly driven, the load on the first pin 14 and the second pin 24 constituting the rotation transmission mechanism 4 can be reduced.

In the component supply device 100 of FIG. 2, the first rotating body 10 is rotated by the motor 9 which is the rotation driving mechanism 3, and the first pin 14 of the first rotating body 10 constituting the rotation transmission mechanism 4 is connected to the first rotating shaft. By rotating around 11, the second rotating body 20 is rotated by the first pin 14 via the second pin 24. However, the present invention is not limited to this configuration, the second rotating body 20 is rotated by the rotation driving mechanism 3, and the rotational motion of the second rotating body 20 is transmitted to the first rotating body 10 by the rotation transmission mechanism 4. It may be configured to do so. An example of this is shown in FIG. In the parts supply device 200 shown in this figure, the motor 9 which is the rotation drive mechanism 3 is provided on the side of the second rotating body 20, and the second rotating body 20 is rotated by the motor 9 and the second rotating body 20 is rotated. The first rotating body 10 is rotated through the first pin 14 by the second pin 24 fixed to the above.

The rotation drive mechanism 3 of FIG. 5 rotates the second rotating body 20 with the motor 9. To be precise, the rotating shaft 28 or the second sub-rotating plate 25 connected to the second rotating body 20 is rotated. In order to rotate the second rotating body 20 with the motor 9, the rotation drive mechanism 3 shown in the figure is provided with a drive gear 19 on the rotating shaft of the motor 9, and the rotating shaft 28 connected to the second rotating body 20 is provided with a driving gear 19. A ring-shaped external gear 29 is provided. Since the rotary drive mechanism 3 rotates the second rotating body 20 via the drive gear 19 and the external gear 29 that are rotated by the rotational torque of the motor 9, the rotational speed of the motor 9 is reduced by the gear ratio and the second There is a feature that the rotation speed of the rotating body 20 can be adjusted. In particular, there is a feature that a strong torque can be obtained while adjusting the rotation speed while using an inexpensive motor 9. Further, since the rotation of the motor 9 is directly transmitted to the second rotating body 20 via the drive gear 19 and the external gear 29, the rotation speed of the second rotating body 20 can be made constant. Therefore, it is possible to improve the accuracy of sorting and alignment on the transfer surface 20A while supplying the component P transferred on the transfer surface 20A at a constant velocity. However, as the transmission mechanism for rotating the second rotating body 20 with the motor 9, a known mechanism other than the gear mechanism, for example, a transmission mechanism such as a gear or a belt can be used.

(Rotation transmission mechanism 4)
The first rotating body 10 and the second rotating body 20 are connected via a rotation transmission mechanism 4 that transmits one rotational motion to the other. The rotation transmission mechanism 4 shown in FIGS. 3 and 4 is arranged so as to guide the first pin 14 connected to the first rotating body 10 and the first pin 14 connected to the second rotating body 20. It includes a pair of second pins 24. The first rotating body 10 includes a first pin 14 projecting in parallel with the first rotating shaft 11 in a region other than the first rotating shaft 11. Further, the second rotating body 20 includes a pair of second pins 24 for guiding the first pin 14 between them in a posture toward the second rotating shaft 21.

The first pin 14 is freely driven in the sliding slit 41 formed between the pair of second pins 24. When either the first rotating body 10 or the second rotating body 20 is rotated, the first pin 14 and the second pin 24 come into contact with each other. That is, when viewed from the second pin 24 side, the first pin 14 inserted into the sliding slit 41 comes into contact with the second pin 24 in the sliding slit 41 and inclines. Alternatively, when viewed from the first pin 14 side, the pair of second pins 24 slide around the first pin 14 and incline. In particular, since the first rotating shaft 11 of the first rotating body 10 and the second rotating shaft 21 of the second rotating body 20 are not coaxial but inclined at an angle α, the first pin 14 and the second pin 24 are orthogonal to each other. Instead, it slides while changing the contact position while maintaining an inclined posture.

(First sub rotating plate 15)
As shown in the cross-sectional view of FIG. 2, the first rotating body 10 has a first sub-rotating plate 15 fixed to its lower surface. The first sub-rotating plate 15 is fixed to the central rod 13 so as to be rotated together with the first rotating body 10, and the first rotating shaft 11 is shared. Further, the diameter of the first sub-rotating plate 15 is smaller than that of the first rotating body 10. For the sake of explanation, an exploded perspective view of the first rotating body 10 separated from the first sub-rotating plate 15 is shown in FIG. 6, and the first sub-rotating plate 15 is further removed from the second opening 26 from this state. An exploded perspective view is shown in FIG. 7, respectively. In this example, the first pin 14 and the second pin 24 are columnar, respectively.

(First pin 14)
The first pin 14 is fixed to the bottom surface side of the first sub-rotating plate 15 and to the outer peripheral side region away from the first rotating shaft 11. The first pin 14 is projected toward the bottom surface side of the first rotating body 10 in a posture parallel to the first rotating shaft 11. The first pin 14 moves along a circular orbit centered on the first rotation axis 11. That is, the first pin 14 rotates about the first rotation shaft 11.

(Second opening 26)
As shown in FIGS. 2, 6 and 7, the second rotating body 20 further opens the second opening 26 on the bottom surface of the first opening 23. The second opening 26 is an inner peripheral region of the second rotating body 20 and is opened in the central portion of the second sub-rotating plate 25 corresponding to the first sub-rotating plate 15.

(Second pin 24)
Further, the pair of second pins 24 are fixed in a posture of projecting toward the center of the second rotation shaft 21. Then, the first pin 14 is inserted into the sliding slit 41 formed between the pair of second pins 24. At this time, at least the tip portions of the pair of second pins 24 are extended so as to overlap the first rotating body 10 in a plan view. As a result, the second pin 24 and the first pin 14 intersect each other with the first sub-rotating plate 15 set in the second opening 26. Then, when the first rotating body 10 and the second rotating body 20 rotate, the second pin 24 slides around the first pin 14. When this is viewed from the second pin 24 side, the first pin 14 slides in the extension direction and the vertical direction of the second pin 24 while changing the inclination angle between the second pins 24. A gap is formed between the first pin 14 and each of the second pins 24 so as to allow such sliding of the first pin 14 and the second pin 24 while tilting. Specifically, as shown in FIG. 8 which is a cross-sectional view taken along the line VIII-VIII of FIG. 1, the first pin is viewed from the end face of the second pin 24 with respect to the plane on which the pair of second pins 24 are located. When the 14 is in an orthogonal (tilted when viewed from the side surface) posture, a gap (d1, d2) is formed between the first pin 14 and the left and right second pins 24. This gap enables the first pin 14 to slide between the pair of second pins 24 in the extension direction and the vertical direction of the second pin 24 while changing the inclination angle. In order to form a gap (d1, d2), the distance (K) between the pair of second pins 24 is formed larger than the diameter D of the first pin 14. Further, the length of the second pin 24 is preferably ½ or more of the radius of the second opening 26 when measured from the root of the second pin 24.

On the other hand, the existence of the gaps (d1, d2) between the first pin 14 and the second pin 24 causes a period in which the first pin 14 and the second pin 24 are in contact with each other, and the first pin is once separated. The impact when the 14 and the second pin 24 collide again will be applied to the contact interface. In particular, since the shapes of the opposing portions of the first pin 14 and the second pin 24 are columnar, the lines are point-shaped at the contact interface where they are in contact with each other, and stress tends to be concentrated. Further, since one of the first rotating body 10 and the second rotating body 20 having an appropriate weight rotates the other, the stress is also considerable, and the strength to withstand this and the durability to withstand repeated use. As a result of the required properties, the first pin 14 and the second pin 24 are made of metal such as SUS. When the metal first pin 14 and the second pin 24 are repeatedly separated and collided with high stress, metal fatigue due to the impact becomes a problem. In particular, when the metal first pin 14 and the second pin 24 that drive the first rotating body 10 and the second rotating body 20 having a considerable weight come into direct contact with each other, the wear at the contact portion becomes large. Therefore, the generation of metal powder is inevitable. In order to prevent this, the rotation drive mechanism 4 applies grease 60 as a lubricant to the contact region 42 where the first pin 14 and the second pin 24 come into contact with each other.

It is preferable that the pair of metal second pins 24 are fixed to the second rotating body 20 in a heat-bonded state with each other. By fixing the second pins 24 to each other in a heat-bonded state in this way, the thermal conductivity is enhanced, the overall heat dissipation is improved, and metal fatigue due to frictional heat at the contact interface with the first pin 14 is reduced. It is possible, and it is expected that reliability will be improved by extending the service life.

(Grease 60)
The grease 60 is applied to the contact area 42 where the first pin 14 and the second pin 24 are in contact with each other. By using an anti-friction material such as grease 60 as a lubricating oil in the contact region 42, the friction at the contact interface between the first pin 14 and the second pin 24 is reduced, and the frictional resistance is reduced, so that the rotation transmission mechanism 4 makes it easier to drive the first rotating body 10 and the second rotating body 20, and can also contribute to reducing the load of the driving force. That is, the grease 60 absorbs the impact and friction at the contact interface when the first pin 14 and the second pin 24 are in contact with each other to protect the first pin 14 and the second pin 24.

The grease 60 applied to the contact region 42 is a semi-solid or semi-fluid at room temperature, preferably NLGI No. 0-No. 3 chassis grease, lithium grease, and lithium grease containing molybdenum can be used. As described above, the grease 60, which is a semi-solid or semi-fluid material, remains in the contact region 42 between the first pin 14 and the second pin 24 for a long period of time, and these wears can be effectively prevented. The grease 60 is preferably applied to the region including the contact interface of the first pin 14 and the second pin 24. In the rotation transmission mechanism 4 shown in FIGS. 8 to 11, grease 60 is applied to almost the entire circumference of the intermediate portion of the first pin 14, and almost the entire area of the facing surface of the second pin 24 facing the first pin 14 is applied. Grease 60 is applied to the surface. The grease 60 is applied to at least the contact area 42 where the first pin 14 and the second pin 24 are in contact (indicated by cross-hatching in FIGS. 10 and 11), but preferably a wide area including the contact area 42, for example. , The entire region including the entire circumference of the first pin 14 and the facing surface of the second pin 24 is applied.

The grease 60 applied to the surfaces of the first pin 14 and the second pin 24 is applied so as to have a predetermined film thickness. The average film thickness of the grease 60 to be applied is adjusted to be, for example, 0.01 to several mm, preferably 0.1 to 3 mm. By increasing the viscosity of the grease 60, the film thickness to be applied is increased, and the grease 60 is held in place for a long period of time while preventing the grease 60 from flowing down from the surfaces of the first pin 14 and the second pin 24. it can. In particular, the grease 60, which is a semi-solid or semi-fluid body, can be retained for a long period of time by applying the grease 60 in a raised state on the surfaces of the first pin 14 and the second pin 24. Therefore, the coating is thicker in the contact region 42 where the first pin 14 and the second pin 24 are in contact with each other, and in the vicinity thereof, particularly in the upper region. For example, in the region above the contact region 42, it is desirable to apply the coating to 3 mm or more, preferably several mm or more.

(Reservoir 45)
Further, the pair of second pins 24 forming the sliding slit 41 are facing surfaces with the first pin 14 so that a large amount of grease 60 can be held, and the grease 60 is applied from the upper part to the upper side of the contact area 42. A storage unit 45 for storing is provided. The pair of second pins 24 shown in FIGS. 8 to 11 are provided with a storage portion 45 for storing grease 60 in the upper surface region of the sliding slit 41 facing the first pin 14. Here, the upper surface region facing the first pin 14 means a region that is the upper surface of the second pin 24 and is unevenly distributed on the first pin 14 side. Therefore, as shown in the figure, when the second pin 24 is a columnar shape having a circular cross-sectional shape, it is perpendicular to the central line m connecting the centers of the two second pins 24, and each second pin 24 is perpendicular to the center line m. The storage portion 45 is formed in a state of being unevenly distributed on the first pin 14 side of the vertical line n passing through the center of the pin 24. As described above, by providing the storage portion 45 on the upper surface of the second pin 24 and unevenly distributed on the first pin 14 side, the grease 60 stored in the storage portion 45 is on the sliding slit 41 side over time. It is made to be supplied to.

In the cross-sectional view, the second pin 24 shown in FIGS. 8 to 11 has an arcuate curved surface facing the first pin 14 moving along the sliding slit 41, and the upper surface of the curved surface. On the side, the upper surface region on the sliding slit 41 side of the upper end of the curved surface is set as the upper surface corner portion, and the storage portion 45 is provided in the upper surface corner portion. As shown in FIG. 10, the second pin 24 is provided with a recessed storage portion 45 by cutting the upper surface corner portion in the extension direction of the second pin 24. The storage portion 45 shown in the figure has a groove shape whose cross-sectional shape is concave in the center, and has a curved surface shape whose bottom surface gradually becomes deeper toward the central portion. The storage portion 45 having this shape can be easily machined. However, the storage portion may have a groove shape having a V-shape, a U-shape, or a U-shape in cross-sectional view.

The storage unit 45 can increase the volume of the storage unit 45 and store a large amount of grease 60 by widening the width for cutting the surface of the second pin 24 and increasing the depth. However, if the surface of the metal pin is cut wide and deep, the strength of the metal pin decreases. Therefore, the width (W) and the cutting depth (H) of the storage portion 45 are determined to be the optimum width (W) and the depth (H) in consideration of the storage amount of the grease 60 and the strength of the metal pin. .. The storage unit 45 has, for example, a width (W) of 20 to 100%, preferably 30 to 80% of the radius of curvature r (corresponding to the radius r in the columnar second pin 24) of the curved surface of the second pin 24. %, More preferably 40 to 60%, and the depth (H) to be 3 to 30%, preferably 5 to 25%, still more preferably 10 to 20% of the radius of curvature r of the curved surface of the second pin 24. To do. As shown in the figure, in the second pin 24 provided with the storage portion 45, the surface is cut to a predetermined depth (H) in order to form the storage portion 45, so that at least this cut depth ( It is possible to store grease 60 having a film thickness equal to or greater than H).

Further, the storage portion 45 is formed on the upper surface side of the second pin 24 and on the upper surface corner portion on the sliding slit 41 side, but with respect to the position where the storage portion 45 is provided, that is, with respect to the central line m and the vertical line n. The positional relationship also affects the amount of grease 60 stored and the degree of supply to the contact area 42. In the cross-sectional view shown in FIG. 11, the storage unit 45 has a storage amount of grease 60 and a contact area 42 depending on the size of the positioning angle (θ) formed by the diameter passing through the midpoint of the horizontal width (W) with the central line m. The degree of supply to can be adjusted. For example, when the positioning angle (θ) of the storage unit 45 is increased to approach 90 degrees, the opening of the storage unit 45 is in an upward posture, and the amount of grease 60 stored can be increased, but the grease 60 is in contact with the storage unit 45. It becomes difficult to supply to the area 42. On the contrary, when the positioning angle (θ) is reduced, the opening of the storage portion 45 approaches sideways, so that the amount of grease 60 stored is reduced. Further, if the positioning angle (θ) is too small, the supply speed of the grease 60 from the storage portion 45 to the contact region 42 becomes high, and it becomes difficult to supply an appropriate amount of the grease 60 over a long period of time. Therefore, the size of the position determination angle (θ) for specifying the opening position of the storage portion 45 is the storage amount of the grease 60, the supply speed to the contact region 42, the viscosity of the grease 60, and the opening width (W) of the storage portion 45. It is adjusted to the optimum angle in consideration of the depth (H) and the like. The positioning angle (θ) at which the storage portion 45 is provided on the second pin 24 is, for example, 30 to 80 degrees, preferably 35 to 70 degrees, and more preferably 40 to 60 degrees. The storage unit 45 shown in the figure has a positioning angle (θ) of about 50 degrees.

As shown in FIG. 10, the storage portions 45 formed at the opposite upper surface corners of the pair of second pins 24 are in a posture parallel to each other and are formed along the sliding slit 41. Here, the storage portion 57 formed in the extension direction of the second pin 24 has its length (L) within the range of the movement locus of the first pin 14 that slides with respect to the pair of second pins 24. I am trying to do it. As a result, the storage unit 45 is arranged so as to cover the entire moving range of the first pin 14 and the second pin 24 that slide with each other. However, the length (L) of the storage unit 45 can be made shorter or longer than the moving range of the first pin 14.

As shown in FIGS. 10 and 11, the storage portion 45 formed in the extension direction of the second pin 24 has a uniform width (W) and has both end edges cut in an arc shape in a plan view. The shape in a plan view is an oval shape. Further, the storage unit 45 may have both edges linear in a plan view and a rectangular shape in a plan view. Further, the reservoir has a shape in a plan view, such as a curved line or a straight line in which both edges are separated from each other downward in a plan view, or a curved line or a straight line in which both edges are separated from each other in a plan view. Can also be trapezoidal.

As described above, the storage unit 45 having a shape that equalizes the overall width (W) can uniformly supply the stored grease 60 against the disappearance of the grease 60 while evenly storing the grease 60. However, the storage unit 45 can also change the width (W) to be cut in various ways. For example, although not shown, the storage portion can have the width of the central portion wider than the width of both end portions. The storage part of this structure can store a large amount of grease in the central region where the contact time between the first pin and the second pin is long. Alternatively, the storage portion can make the width of the central portion narrower than the width of both end portions. In the storage portion of this structure, the volume of the storage portion can be increased while reducing the decrease in the strength of the second pin by narrowing the width of the central region where the contact time between the first pin and the second pin becomes long.

As described above, the structure in which the second pin 24 is provided with the storage portion 45 is such that even when the grease 60 applied to the contact region 42 of the first pin 14 and the second pin 24 disappears over time, this region remains. A new grease 60 can be supplied from the storage unit 45. In this way, the second pin 24 capable of storing the grease 60 in the storage unit 45 can sequentially supply the grease 60 that disappears with time, so that the first pin 14 and the second pin 24 can directly supply the grease 60 over a long period of time. It is possible to prevent them from coming into contact with each other and effectively prevent them from wearing each other.

Further, FIG. 9 is an enlarged view of a state in which the first rotating body 10 and the second rotating body 20 are rotated from the state shown in FIG. 8 and the first pin 14 is in an inclined posture with respect to the second pin 24. Shown. As shown in this figure, in the state where the first pin 14 is tilted with respect to the second pin 24, the outer peripheral surface of the tilted first pin 14 is the third as compared with the vertical state shown in FIG. The state of approaching the inner peripheral surface of the second pin 24 narrows the gaps (d1, d2) between the first pin 14 and the second pin 24. In this way, even when the positional relationship between the first pin 14 and the second pin 24 changes and the gap between the first pin 14 and the second pin 24 changes, the grease applied to the contact interface 60 reduces wear due to direct contact.

In the above example, an example using the first pin 14 and the second pin 24 formed in a cylindrical shape has been described, but in the present invention, the shapes of the first pin and the second pin do not necessarily have to be cylindrical. It suffices if the first pin and the second pin have a shape that allows them to easily slide at the contact interface. Typically, at least the interface between the first pin and the second pin that comes into contact with each other is a curved surface. In particular, in the example of FIG. 8, the first pin 14 and the second pin 24 are configured so that the end faces are circular and the columnar side surfaces are brought into contact with each other. It may be an ellipse or a curved curved surface. In the present specification, such a shape having a curved surface in a part thereof is referred to as a pin for convenience.

For example, as shown in FIGS. 12 and 13, the pair of second pins 24 may have a shape in which the facing surfaces are curved surfaces and the other portions are flat or prismatic. In the example of the second pin 24 shown in these figures, the surface of the pair of second pins 24 facing the first pin 14 is a curved surface, and the upper and lower surfaces are formed in a flat shape. Also in the second pin 24 having the shape shown in FIGS. 12 and 13, a storage portion for storing the grease 60 in the upper surface region above the contact region 42 with the first pin 14 and facing the first pin 14. 45 is provided. The pair of second pins 24 shown in FIGS. 12 and 13 also have an arcuate curved surface whose facing surface facing the first pin 14 moving along the sliding slit 41 is an arcuate curved surface, which is the upper surface side of the curved surface. Therefore, the upper surface region on the sliding slit 41 side of the upper end of the curved surface is set as the upper surface corner portion, and the storage portion 45 is provided at the opposite upper surface corner portion. The second pin 24 is cut in the extension direction of the second pin 24 at the opposite upper surface corner to provide a recessed storage portion 45.

Further, in the above-described embodiment, the example in which the pair of second pins 24 is composed of individual members has been described, but the pair of second pins may be integrally formed. In the example shown in FIG. 12, a metal block is cut to form a pair of second pins 24 in a U-shape in a plan view. With this configuration, the heat capacity of the second pin 24 can be increased, and heat due to friction with the first pin 14 can be easily absorbed. Further, the thermal conductivity of the second pin 24 is also improved, the heat dissipation property is also improved, deterioration due to friction with the first pin 14 is suppressed, and the life is further extended and the reliability is improved.

(Other examples of rotation transmission mechanism)
In the component supply devices 100 and 200 of the above embodiments, as the rotation transmission mechanism 4, the first rotating body 10 is a first pin protruding in parallel with the first rotating shaft 11 in a region other than the first rotating shaft 11. An example is shown in which the second rotating body 20 is provided with a pair of second pins 24 for guiding the first pin 14 in a posture toward the second rotating shaft 21. As shown in FIGS. 14 to 18, a pair of first rotating bodies 10 fixed to the first rotating body 10 in a posture of projecting parallel to the first rotating shaft 11 along a circumferential orbit centered on the first rotating shaft 11. It can also be composed of one pin 14 and a second pin 24 fixed to the second rotating body 20 in a posture toward the second rotating shaft 21 so as to be guided between the pair of first pins 14. In these figures, the same components as those in the above-described embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

In the rotation transmission mechanism 4 of the component supply device 300 shown in FIGS. 14 to 18, the second pin 24 is guided by a sliding slit 41 formed between the pair of first pins 14, and the pair of first pins is guided. The 14 and the second pin 24 are driven in an interlocking state. When either the first rotating body 10 or the second rotating body 20 is rotated, the pair of first pin 14 and the second pin 24 come into contact with each other. That is, when viewed from the first pin 14 side, the second pin 24 inserted into the sliding slit 41 comes into contact with and interlocks with the first pin 14 in the sliding slit 41. Alternatively, when viewed from the second pin 24 side, the pair of first pins 14 slide around the second pin 24 and interlock. In particular, since the first rotating shaft 11 of the first rotating body 10 and the second rotating shaft 21 of the second rotating body 20 are not parallel and are inclined at an angle α, the first pin 14 and the second pin 24 are orthogonal to each other. Instead, it slides while changing the contact position while maintaining an inclined posture.

(First pin 14)
The pair of first pins 14 are fixed to the bottom surface side of the first sub-rotating plate 15 and to the outer peripheral side region away from the first rotating shaft 11. The pair of first pins 14 are arranged along a circumferential orbit centered on the first rotation axis 11 at predetermined intervals. The pair of first pins 14 shown in the figure are in a parallel posture with the first rotating shaft 11 and are provided so as to project toward the bottom surface side of the first rotating body 10.

(Second pin 24)
The second pin 24 is fixed in a posture that projects toward the center of the second rotation shaft 21. The second pin 24 is inserted into a sliding slit 41 formed between the pair of first pins 14. At this time, at least the tip portion of the second pin 24 is extended so as to overlap the first rotating body 10 in a plan view. As a result, the first pin 14 and the second pin 24 intersect each other with the first sub-rotating plate 15 set in the second opening 26. Then, when the first rotating body 10 and the second rotating body 20 rotate, the first pin 14 slides around the second pin 24. When this is viewed from the first pin 14 side, the second pin 24 slides up and down while changing the inclination angle between the first pins 14. A gap is formed between each of the first pin 14 and the second pin 24 so as to allow such sliding of the first pin 14 and the second pin 24 while tilting.

In the rotation transmission mechanism 4 having the structure shown in FIGS. 14 to 18, the gap provided between each of the first pin 14 and the second pin 24 may be smaller than the gap in the rotation transmission mechanism 4 described above. it can. In the rotation transmission mechanism 4 having the structure shown in FIGS. 14 to 18, as shown in FIG. 16, the pair of first pins 14 inclined in the vertical plane are the second pins 24 having a circular outer shape. This is because the tilted first pin 14 is not compressed by the second pin 24 because it tilts along the outer peripheral surface. However, as shown in FIG. 15, the pair of first pins 14 are along the rotation trajectory of the first rotating body arranged in an inclined posture with respect to the second rotating body 20 in which the second pin 24 is arranged. Since it rotates, the rotation locus of the pair of first pins 14 has an elliptical shape with respect to the rotation locus of the second pin 24. Therefore, the second pin 24 that moves in the sliding gap of the pair of first pins 14 has a section that slides in a posture that is slightly inclined with respect to the pair of first pins 14. Therefore, by forming a gap between each of the first pin 14 and the second pin 24, the pair of first pin 14 and the second pin 24 can be rotationally driven while being reasonably interlocked with each other.

As shown in FIG. 18, the gap (d1, d2) formed between the pair of the first pin 14 and the second pin 24 causes the second pin 24 to change the inclination angle between the first pins 14. Smooth movement that slides up and down. In order to form a gap (d1, d2), the distance between the pair of first pins 14 is formed larger than the diameter of the second pin 24. Further, by arranging the second pin 24 so that its center coincides with the center of the distance between the first pins 14, the gaps formed on both sides can be made equal. This rotation transmission mechanism 4 also applies grease 60 as a lubricant to the contact region 42 of the first pin 14 and the second pin 24 in order to reduce wear due to contact between the first pin 14 and the second pin 24. .. This grease contains the above-mentioned NLGI No. 0-No. 3 chassis grease, lithium grease, lithium grease containing molybdenum, etc. can be used.

(Reservoir 45)
The second pin 24 guided by the pair of first pins 14 is to store the grease 60 on the surface facing the first pin 14 and above the contact area 42 so that a large amount of grease 60 can be held. The storage unit 45 is provided. The second pin 24 shown in FIGS. 17 and 18 is provided with a storage portion 45 for storing grease 60 in the upper surface region of the contact region 42 facing the first pin 14. Here, the upper surface region facing the first pin 14 means a region facing the first pin 14 located on both sides of the upper surface of the second pin 24. Therefore, as shown in FIG. 18, when the second pin 24 is a columnar shape having a circular cross-sectional shape, a pair of the second pins 24 are symmetrical on both sides of the vertical line n passing through the center of the second pin 24. A reservoir 45 is formed. In this way, by providing the pair of storage portions 45 on both sides of the upper surface of the upper surface region of the second pin 24, the grease 60 stored in the storage portions 45 is supplied to the sliding slit 41 side over time. I am trying to do it.

The second pin 24 that moves the sliding slit 41 has an arcuate curved surface whose facing surface facing the pair of first pins 14 is an arc-shaped curved surface in a cross-sectional view, and is the upper surface side of the curved surface and is a curved surface. The upper surface region on the first pin side of the upper end is set as the upper surface corner portion, and the storage portion 45 is provided in the upper surface corner portion. That is, the columnar second pin 24 is provided with a recessed storage portion 45 by cutting the upper surface corners on both sides of the upper surface region in the extension direction of the second pin 24. The volume of the storage portion 45 can also be adjusted by the width and depth of the recess formed by cutting the surface of the second pin 24 in the same manner as described above. Further, the pair of storage portions 45 formed on both sides of the second pin 24 along the extension direction of the second pin 24 are in a posture parallel to each other and have a length (L) of the pair of first pins 14. It is designed to be within the range of the movement trajectory of. This makes it possible to cover the entire moving range of the first pin 14 and the second pin 24 that slide with each other. However, the length (L) of the storage unit 45 can be made shorter or longer than the moving range of the first pin 14. The storage portion 45 formed in the extension direction of the second pin 24 may have an oval shape or a rectangular shape in a plan view by making the width (W) uniform as described above. Or it can be trapezoidal.

As described above, the storage unit 45 having a shape that equalizes the overall width (W) can uniformly supply the stored grease 60 against the disappearance of the grease 60 while evenly storing the grease 60. However, the storage unit 45 can also change the width (W) to be cut in various ways. For example, although not shown, the storage portion can have the width of the central portion wider than the width of both end portions. The storage part of this structure can store a large amount of grease in the central region where the contact time between the first pin and the second pin is long.

As described above, in the structure provided with the storage portions 45 on both sides of the upper surface region of the second pin 24, the grease 60 applied to the contact region 42 of the pair of first pin 14 and the second pin 24 disappeared over time. Even in this case, a new grease 60 can be supplied from the storage unit 45 to this region. In this way, the second pin 24 capable of storing the grease 60 in the storage unit 45 can sequentially supply the grease 60 that disappears with time, so that the pair of the first pin 14 and the second pin 24 can be supplied for a long period of time. Can be prevented from coming into direct contact with each other, effectively preventing them from coming into contact with each other and wearing.

In the above parts supply devices 100, 200, and 300, an outer peripheral wall 51 is arranged along the outer peripheral edge of the second rotating body 20. The second rotating body 20 having the outer peripheral wall 51 can increase the rotating speed to prevent the component P from jumping out of the second rotating body 20 and falling due to centrifugal force. Therefore, the parts supply devices 100, 200, and 300 can rotate the second rotating body 20 at high speed and discharge a large amount of parts P in a unit time. However, the outer peripheral wall does not necessarily have to be provided. This is because the component supply device 100 that slowly rotates the second rotating body 20 does not cause the component P mounted on the second rotating body 20 to fall outward due to acceleration.

Further, the above-mentioned component supply devices 100, 200, and 300 can be provided with a mechanism for selecting, aligning, and carrying out the components P transferred by the second rotating body 20 according to the purpose. The component supply device 100 shown in FIG. 1 is provided with a mechanism for sorting the postures of a large number of components P to be transferred on the transfer surface 20A of the second rotating body 20 and arranging them in a row to carry them out in the transfer direction. There is. The component supply device 100 of FIG. 1 includes a stacking release unit 32 that eliminates the overlap of the components P transferred by the second rotating body 20, a single row guide 33 that arranges the components P transferred by the outer ring plate 2 in a row, and so on. It is provided with a sorting mechanism 34 that sorts the posture of the component P to be transferred. In the component supply devices 100, 200, and 300, the components P supplied from the first rotating body 10 to the second rotating body 20 are passed through the delamination unit 32 to form a single stage, and further passed through the one-row guide 33 to form a single row. Transfer to the ascending section 6. In the ascending section 6, the sorting mechanism 34 detects the direction of the component P and drops the component in the opposite posture from the transfer surface 20A of the second rotating body 20 to the mounting surface 10A of the first rotating body 10. The sorting mechanism 34 allows parts in a normal posture to pass through the outer ring plate 2 without dropping and discharges the parts to the outside.

In the component supply device 100 shown in the figure, a sorting guide 34A is arranged as a sorting mechanism 34 on the rising portion 6 of the second rotating body 20. However, the parts supply device does not specify a mechanism for selecting and aligning parts to be transferred by the second rotating body as the above mechanism. The parts to be transferred are sorted into a desired state by various mechanisms according to their type and shape, and are aligned and discharged.

The component supply device according to the present invention can be suitably used for supplying screws, rings, pins, semiconductor components and the like.
