Description

The present invention relates to a component supply device for supplying components.

Parts feeders are used to transfer and supply parts such as screws and rings. The inventor of the present application previously developed a parts feeder shown in FIG. 19 (see Patent Document 1). This parts feeder includes an inner disk 91, an outer ring plate 92 arranged outside 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. 93. The outer ring plate 92 is arranged on the same plane as the inner disk 91, and has a supply portion 95 to which the parts PT are supplied from the inner disk 91, and a rising/falling portion 96 arranged at a position higher than the inner disk 91. , and transfers the parts PT supplied from the inner disk 91 from the supply unit 95 to the ascending/falling unit 96 . As a result, the parts PT can be ejected while reducing the noise level while minimizing damage during transportation.

The drive mechanism 93 rotates the outer ring plate 92 together with the inner disc 91 with a common reduction motor 99 . In order to rotate the inner disc 91 and the outer ring plate 92 together by the reduction motor 99, the inner disc 91 is fixed with a drive pin 98 protruding from the bottom surface. A pair of parallel pins 97 that guide the drive pin 98 are fixed to the outer ring plate 92 . Parallel pins 97 are fixed inwardly to the upper surface of disc 94 which is fixed to outer ring plate 92 . A driving pin 98 is inserted between the parallel pins 97 so as to be able to move in and out and to move along the parallel pins 97 . In the drive mechanism 93 , a deceleration motor 99 rotates a drive pin 98 , and the drive pin 98 rotates the outer ring plate 92 via a parallel pin 97 . Since the rotation centers of the inner disk 91 and the outer ring plate 92 are inclined with respect to each other, the drive pin 98 slides between the parallel pins 97 to rotate the outer ring plate 92 .

Since the inner disk 91 and the outer ring plate 92, which are two rotating bodies having different rotation axes, are rotated by the common deceleration motor 99, the parallel pin 97 and the driving pin 98, which are joints connecting them, are orthogonal to each other. It is connected with a gap so that it can be tilted obliquely.

Japanese Patent Application Laid-Open No. 2004-010287

However, due to the presence of this gap, the parallel pin and the driving pin repeatedly come into and out of contact with each other, and as a result, there is a problem that impact and friction are applied to the pin at the time of contact. That is, when cylindrical pins are crossed and brought into contact with each other, the contact is point-like rather than linear, and stress tends to be concentrated. In addition, there is a problem that the contact portion heats up due to friction and wears out due to sliding in a point-like contact state. Furthermore, when the rotary motion is intermittent, the impact at the time of stopping or re-driving becomes large. As a result of such impact forces being applied to the pins, the pins could be damaged. In particular, when the pin is made of metal, if the metal wears due to collision or friction and generates metal powder, the working environment deteriorates. .

In order to prevent wear due to contact between the pins as described above, 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 wear between the metal pins. In general, grease, which is a lubricant, does not disappear in a short period of time, but disappears over time, causing the above problems.

SUMMARY OF THE INVENTION The present invention has been made in view of such a background, and one of its objects is to provide a component feeding device capable of maintaining an environment for a long period of time in which contact portions between pins are coated with grease. It is in.

(Embodiment 1)
A component supply device according to one embodiment of the present invention is shown in FIGS. 1 to 4. 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 schematic horizontal cross section of the parts supply device of FIG. FIGS. 4A and 4B are enlarged cross-sectional views showing states in which the first pin and the second pin in FIG. 2 have moved to the positions shown in FIG. 3, respectively.

The component supply device 100 shown in these figures is a device for aligning and carrying out parts P to be supplied, such as screws, rings, pins, ICs, etc., from a state in which they have been thrown in separately. Here, a flanged ring will be described as an example, but the present invention is not limited to disk-shaped parts such as flanged rings. It can be applied to parts having a polygonal pyramidal shape, or to hollow parts such as cylindrical and rectangular tubes. In addition, not only parts with the same or symmetrical front and back sides, but also asymmetrical parts with directionality, such as bearings with flanges, parts with directionality where the direction is specified by the outer peripheral protrusion, and parts with flanges It can be applied to parts that need to be aligned with specified postures and orientations, such as screws that have a screw head and a cylindrical threaded portion, or semiconductor chips that have a defined mounting surface.

The component supply device 100 shown in FIGS. 1 and 2 includes a first rotating body 10 that is rotatably disposed within a first plane 12 about a first rotating shaft 11, and is larger than the first rotating body 10, A first opening 23 is formed in the center, and the first rotating body 10 is exposed from the first opening 23 . A second rotating body 20 rotatably disposed within a second plane 22 inclined with respect to the plane 12, and a rotation drive mechanism 3 for rotating either the first rotating body 10 or the second rotating body 20. Then, by rotating either the first rotating body 10 or the second rotating body 20 with the rotation drive mechanism 3, the rotational motion is transmitted to the other of the first rotating body 10 or the second rotating body 20. A rotation transmission mechanism 4 for rotating this is provided.

(First Rotating Body 10, Second Rotating Body 20)
The first rotating body 10 is rotatably arranged within the first plane 12 around the first rotating shaft 11 . Also, the second rotating body 20 is arranged outside the first rotating body 10 . The second rotating body 20 has a second plane inclined with respect to the first plane 12 about a second rotary shaft 21 inclined from the first rotary shaft 11 as indicated by a dashed line in the cross-sectional view of FIG. 22 is rotatably arranged. The first rotating body 10 receives the supply of the parts P from an external connection device (not shown) such as a hopper, sends the parts P to the second rotating body 20, and from the second rotating body 20, the parts P in the aligned posture are delivered. Discharge. The top surface of the first rotating body 10 is used as a mounting surface 10A for storing the parts P, and the top surface of the second rotating body 20 is used as a transfer surface 20A for transferring the parts P.

The structure in which the second rotating body 20 is arranged outside the first rotating body 10 temporarily stores a large number of components P supplied from an external connection device on the mounting surface 10A that is the upper surface of the first rotating body 10, The parts P can be supplied from the first rotating body 10 to the transfer surface 20A, which is the upper surface of the second rotating body 20. As shown in FIG. 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 once, and to prevent the amount of the parts P supplied to the second rotating body 20 from decreasing. Thus, an appropriate amount of parts P can be efficiently supplied to the second rotating body 20. - 特許庁In particular, according to this structure, it is possible to prevent a large number of parts P from being supplied to the second rotating body 20 in a lump, so that the parts P can be effectively prevented from being damaged by rubbing against each other.

The second rotating body 20 is arranged in an inclined posture with respect to the first rotating body 10 . Furthermore, the second rotating body 20 is arranged so that a part thereof is connected to the first rotating body 10 so that the parts P are supplied from the first rotating body 10 . The second rotating body 20 includes a supply section 5 to which the component P is supplied from the first rotating body 10, and an ascending section 6 arranged at a position higher than the first rotating body 10. The part P supplied from the body 10 is transferred from the supply section 5 to the ascending section 6. - 特許庁The second rotating body 20 is arranged relatively inclined with respect 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 a horizontal posture, or the first rotating body may be tilted with the second rotating body in a horizontal posture.

As shown in FIG. 2, the structure in which both the first rotating body 10 and the second rotating body 20 are inclined in opposite directions with respect to the horizontal plane allows the second rotating body 20 to move from the supply section 5 of the parts P to the ascending section 6. The first rotating body 10 is inclined downward from the supply part 5 toward the ascending part 6 of the second rotating body 6 by inclining upward. This structure can reduce the inclination angle of the first rotating body 10 and the second rotating body 20 and increase the drop between the second rotating body 20 and the first rotating body 10 in the ascending portion 6 . Although not shown, the structure for tilting only the second rotating body is such that the first rotating body is arranged in a horizontal plane and the second rotating body is inclined upward from the supply section toward the ascending section so that the A drop 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 section toward the ascending portion of the second rotating body, and the second rotating body and the first rotating body are inclined at the ascending section. A drop is provided for one rotating body.

The first rotating body 10 and the second rotating body 20 which are inclined with respect to each other are partly arranged on the same plane to form a supply section 5 for supplying the parts P from the first rotating body 10 to the second rotating body 20 . The vertical difference between the first rotating body 10 and the second rotating body 20 increases as the distance from the supply section 5 increases, and the portion where the vertical difference is greatest or the vicinity thereof is defined as the ascending section 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 inclined 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 blocking 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 at the center thereof, and the first opening 23 is approximately 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, the edge of the first rotating body 10 matches the inner circumference of the second rotating body 20 in cross-sectional view inside the first opening 23 of the second rotating body 20. The supply unit 5 for the parts P is arranged in such a manner as to With this arrangement, the upper surface of the first rotating body 10 and the upper surface of the second rotating body 20 are partially connected, and the parts P supplied to the upper surface of the first rotating body 10 are pushed out by the supply 31. , and can be configured to be guided by the upper surface of the second rotating body 20 . In particular, as shown in the cross-sectional view of FIG. 2 , the second rotating body 20 is inclined downward toward the outer circumference at the portion guided from the first rotating body 10 to the second rotating body 20 . The part P transferred from the side of the first rotating body 10 to the side of the second rotating body 20 can be easily lured into the second rotating body 20 by the weight of the part P itself.

The upper surface of the second rotating body 20 is a ring-shaped transfer surface 20A that continues in the direction in which the component P is transferred. 20 A of transfer surfaces formed on the 2nd rotating body 20 are formed in the ring shape along the circumference|surroundings of the 1st rotating body 10, and transfer the components P supplied from the 1st rotating body 10. As shown in FIG. The rotating second rotating body 20 transfers the part P in a circular orbit. Therefore, the transfer surface 20</b>A is provided so as to follow a circular orbit centered on the second rotation shaft 21 that is the center of rotation of the second rotor 20 . 20 A of transfer surfaces of the 2nd rotary body 20 shown in a figure are made into planar shape. However, in the component 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 components to be transferred. .

The first rotating body 10 and the second rotating body 20 can be manufactured by cutting a single metal plate into a circular shape using 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 made of separate metal plates. The first rotating body 10 has an outer diameter of 10 to 80 cm, for example, so that it can store a large number of parts P to be supplied. If the first rotating body 10 is enlarged, a large number of large parts P can be stored. The width of the transfer surface 20A of the second rotating body 20 is designed to be sufficiently wide compared to the outer diameter of the part P so that the part P can be placed thereon and transferred. The width of the transfer surface 20A of the second rotating body 20 varies depending on the outer diameter of the parts P to be transferred and the number of rows of the parts P to be transferred. In a device that aligns and transports parts P, which are attached rings, the distance is 3 to 15 cm.

The first rotating body 10 and the second rotating body 20 described above are connected to the frame 50 so as to be rotatable. A center rod 13 having a first rotation shaft 11 as its axis is fixed to the center of the first rotor 10 , and the center rod 13 is rotatably connected to the frame 50 via a bearing. The second rotating body 20 has a second sub-rotating plate 25 fixed to its lower surface via a blocking wall 27, and a cylindrical rotating shaft 28 fixed to the center of the second sub-rotating plate 25 is supported by a bearing. It is rotatably connected to the frame 50 via. The second rotating body 20 and the first rotating body 10 are connected to the frame 50 so as to 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 cross-sectional view of FIG. is transmitted to the other of the first rotating body 10 or the second rotating body 20 to 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 revolutions. In the example of FIGS. 1 and 2 , the rotary drive mechanism 3 is composed of a motor 9 . This motor 9 is connected to a central rod 13 fixed to the center of the first rotor 10 and rotates the first rotor 10 in the direction indicated by the arrow in FIG. As such a motor 9, an induction motor can be used, and a deceleration motor or a stepping motor can also be used.

The component supply device 100 of FIG. 2 rotates the second rotating body 20 together with the first rotating body 10 with one motor 9 . The first rotating body 10 and the second rotating body 20 are connected via the rotation transmission mechanism 4 so that the motor 9 rotates the first rotating body 10 and the second rotating body 20 together. As such a rotation transmission mechanism 4 , the first rotating body 10 has a first pin 14 that protrudes downward and is fixed parallel to the first rotating shaft 11 , as shown in FIGS. 2 and 3 . A pair of second pins 24 that guide the first pins 14 are fixed to the second rotor 20 . The pair of second pins 24 are arranged parallel to each other and 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 as to be able to move in and out and to move along the second pins 24 . This rotation transmission mechanism 4 is driven by a motor 9, and a first pin 14 rotating along a circular orbit centered on a first rotating shaft 11 rotates a second rotating body 20 via a second pin 24. . Since the centers of rotation of the first rotating body 10 and the second rotating body 20 are inclined to each other, the first pin 14 slides between the second pins 24 to rotate the second rotating body 20 .

A first pin 14 provided at one location on the first rotating body 10 and a second pin 24 provided at one location on the second rotating body 20 are located at positions P1, P2, and P3 in the enlarged view of FIG. FIG. 4 shows an enlarged sectional view at one time. In this way, the first pin 14 and the second pin 24 that constitute the rotation transmission mechanism 4 have rotating shafts that are inclined with respect to each other, but are slid on the contact interface so that the rotation of one of the pins is shifted to the rotation of the other. can be transmitted to

A component supply device 100 shown in FIG. 2 has a structure in which a motor 9 that is a rotation drive mechanism 3 rotates a first rotating body 10 . In this parts supply device 100 , the motor 9 rotates the first rotating body 10 , and the torque of this rotation is transmitted 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 rotor 10, the first rotor 10 can be rotated at a predetermined number of revolutions. This parts supply device 100 rotates the center rod 13 of the first rotating body 10 directly by the motor 9 which is the rotation driving mechanism 4, and also rotates the second rotating body 20 via the rotation transmission mechanism 4. A transmission mechanism such as a gear mechanism for rotating the first rotating body 10 and the second rotating body 20 is not required. Therefore, the second rotating body 20 can be rotationally driven with a simple structure in which the rotating shaft 28 connected to the second rotating body 20 is fixed to the frame 50 via a bearing. Moreover, since the first rotating body 10 is directly driven by the motor 9, the first rotating body 10, which is heavy due to the large number of parts P stacked thereon, can be stably rotated. In particular, since the first rotating body 10, which is heavy due to the supply of many parts, is directly driven, there is also the feature that the load on the first pin 14 and the second pin 24 constituting the rotation transmission mechanism 4 can be reduced.

The component supply device 100 of FIG. 2 rotates the first rotating body 10 by the motor 9 that is the rotation driving mechanism 3, and rotates the first pin 14 of the first rotating body 10 that constitutes the rotation transmission mechanism 4 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, and the rotation drive mechanism 3 rotates the second rotor 20, and the rotation transmission mechanism 4 transmits the rotational motion of the second rotor 20 to the first rotor 10. It may be configured to Such an example is shown in FIG. A component supply device 200 shown in this figure has a motor 9 which is a rotation drive mechanism 3 on the side of a second rotating body 20, rotates the second rotating body 20 with the motor 9, and rotates the rotating second rotating body 20. The first rotating body 10 is rotated via the first pin 14 with the second pin 24 fixed to.

The rotation drive mechanism 3 of FIG. 5 rotates the second rotor 20 with the motor 9 . More precisely, 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 driving mechanism 3 shown in the figure has a driving gear 19 provided on the rotating shaft of the motor 9 and a rotating shaft 28 connected to the second rotating body 20. A ring-shaped external gear 29 is provided. This rotary drive mechanism 3 rotates the second rotating body 20 via the drive gear 19 rotated by the rotational torque of the motor 9 and the external gear 29, so that the rotation speed of the motor 9 is reduced by the gear ratio to reduce the second rotation speed. It has 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 rotational speed while using an inexpensive motor as the motor 9 . Furthermore, since the rotation of the motor 9 is directly transmitted to the second rotor 20 via the drive gear 19 and the external gear 29, the rotational speed of the second rotor 20 can be made constant. Therefore, the accuracy of sorting and alignment on the transfer surface 20A can be improved while supplying the parts P transferred on the transfer surface 20A at a constant speed. 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 the rotational motion of one to the other. The rotation transmission mechanism 4 shown in FIGS. 3 and 4 is arranged to guide the first pin 14 connected to the first rotating body 10 and the second rotating body 20 to guide the first pin 14. and a pair of second pins 24 . The first rotating body 10 has a first pin 14 protruding parallel to the first rotating shaft 11 in a region other than the first rotating shaft 11 . The second rotating body 20 also has a pair of second pins 24 that guide the first pin 14 therebetween in a posture facing the second rotating shaft 21 .

The first pin 14 freely drives in a 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 contacts the second pin 24 within the sliding slit 41 and tilts. Alternatively, when viewed from the first pin 14 side, the pair of second pins 24 slide around the first pin 14 and tilt. 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 perpendicular to each other. Instead, it slides while changing the contact position while maintaining the tilted 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 shares the first rotating shaft 11 . Also, the diameter of the first sub rotor plate 15 is smaller than that of the first rotor 10 . For the sake of explanation, FIG. 6 is an exploded perspective view of the first rotating body 10 separated from the first sub-rotating plate 15, and the first sub-rotating plate 15 is removed from the second opening 26 in 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 each cylindrical.

(first pin 14)
The first pin 14 is fixed to a region on the bottom surface side of the first sub-rotary plate 15 and on the outer peripheral side away from the first rotating shaft 11 . The first pin 14 is parallel to the first rotating shaft 11 and protrudes toward the bottom surface of the first rotating body 10 . This first pin 14 moves along a circular orbit centered on the first rotating shaft 11 . That is, the first pin 14 rotates around the first rotating shaft 11 .

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

(second pin 24)
Furthermore, a pair of second pins 24 are fixed in a posture protruding toward the center of the second rotating shaft 21 . 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 plan view. As a result, the second pin 24 and the first pin 14 cross each other with the first sub-rotary plate 15 set in the second opening 26 . When the first rotating body 10 and the second rotating body 20 rotate, the second pin 24 slides around the first pin 14 . When viewed from the second pin 24 side, the first pin 14 slides in the extending direction of the second pin 24 and in the vertical direction 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 the first pin 14 and the second pin 24 to slide while being inclined. Specifically, as shown in FIG. 8, which is a cross-sectional view taken along line VIII-VIII of FIG. A gap (d1, d2) is formed between the first pin 14 and the left and right second pins 24 when the pins 14 are in an orthogonal (inclined when viewed from the side) posture. This gap allows the first pin 14 to slide between the pair of second pins 24 in the extending direction and the vertical direction while changing the inclination angle. In order to form the gaps (d1, d2), the gap (K) between the pair of second pins 24 is made larger than the diameter D of the first pin 14. As shown in FIG. Moreover, it is preferable that the length of the second pin 24 is 1/2 or more of the radius of the second opening 26 when measured from the base of the second pin 24 .

On the other hand, due to the presence of gaps (d1, d2) between the first pin 14 and the second pin 24, a period in which the first pin 14 and the second pin 24 are separated from each other and a period in which they are in contact with each other are generated. The impact when 14 and the second pin 24 collide again will be applied to the contact interface. In particular, since the first pin 14 and the second pin 24 are cylindrical in shape, the contact interface where they are in contact with each other has a dotted shape where lines intersect, and stress tends to concentrate. Furthermore, since one of the first rotating body 10 and the second rotating body 20 having a corresponding 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, the first pin 14 and the second pin 24 are made of metal such as SUS. When the metallic first pin 14 and the metallic second pin 24 are repeatedly separated and collided under high stress, metal fatigue due to the impact becomes a problem. In particular, when the first pin 14 and the second pin 24 made of metal for driving the first rotor 10 and the second rotor 20 having a considerable weight come into direct contact with each other, the contact portion is greatly worn. Therefore, the generation of metal powder is unavoidable. In order to prevent this, the rotation drive mechanism 4 applies grease 60 as a lubricant to the contact area 42 where the first pin 14 and the second pin 24 contact each other.

The pair of metal second pins 24 are preferably fixed to the second rotating body 20 in a thermally coupled state. In this way, by fixing the second pins 24 in a thermally bonded state, the thermal conductivity is increased, the heat dissipation of the whole is improved, and the metal fatigue caused by the frictional heat at the contact interface with the first pin 14 is reduced. It is expected that reliability will improve due to longer life.

(Grease 60)
Grease 60 is applied to the contact area 42 where the first pin 14 and the second pin 24 contact. By using an anti-friction material, which is a lubricating oil such as grease 60, in the contact area 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, resulting in a rotation transmission mechanism. 4 makes it easier to drive the first rotating body 10 and the second rotating body 20, and can contribute to reducing the load of the driving force. That is, the grease 60 absorbs impact and friction at the contact interface when the first pin 14 and the second pin 24 contact each other, thereby protecting the first pin 14 and the second pin 24 .

The grease 60 applied to the contact area 42 is semi-solid or semi-fluid at room temperature, preferably NLGI No. 0 to No. No. 3 chassis grease, lithium grease, and lithium grease containing molybdenum can be used. In this way, the semi-solid or semi-fluid grease 60 can remain in the contact area 42 between the first pin 14 and the second pin 24 for a long period of time to effectively prevent wear thereof. Grease 60 is preferably applied to a region including the contact interface between first pin 14 and second pin 24 . In the rotation transmission mechanism 4 shown in FIGS. 8 to 11, grease 60 is applied to substantially the entire circumference of the middle portion of the first pin 14, and substantially the entire surface of the second pin 24 facing the first pin 14 is greased. is coated with grease 60. The grease 60 is applied at least to the contact area 42 (indicated by cross-hatching in FIGS. 10 and 11) where the first pin 14 and the second pin 24 contact, but preferably a wide area including the contact area 42, such as , over the entire area including the entire circumference of the first pin 14 and the facing surface of the second pin 24 .

The grease 60 applied to the surfaces of the first pin 14 and the second pin 24 is applied to a predetermined film thickness. The average film thickness of the applied grease 60 is adjusted to, for example, 0.01 to several mm, preferably 0.1 to 3 mm. By increasing the viscosity of the grease 60, the thickness of the applied film is increased to prevent the grease 60 from flowing down from the surfaces of the first pin 14 and the second pin 24, while holding the grease 60 in place for a long period of time. can. In particular, the semi-solid or semi-fluid grease 60 can be maintained for a long period of time by applying it to the surfaces of the first pin 14 and the second pin 24 in a raised state. Therefore, the contact area 42 where the first pin 14 and the second pin 24 contact and the vicinity thereof, particularly the upper area, are coated thicker. For example, in the area above the contact area 42, it is desirable to apply the adhesive to a thickness of 3 mm or more, preferably several mm or more.

(Storage unit 45)
Further, the pair of second pins 24 forming the sliding slit 41 are arranged so that a large amount of grease 60 can be held on the surfaces facing the first pins 14 and extending from the upper part of the contact area 42 to the upper part thereof. A storage section 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 an upper surface area facing the first pin 14 above the sliding slit 41 . Here, the upper surface region facing the first pin 14 means the upper surface of the second pin 24 and the region unevenly distributed on the first pin 14 side. Therefore, as shown in the figure, when the second pin 24 has a cylindrical shape with a circular cross-sectional shape, each second pin 24 is perpendicular to the center line m connecting the centers of the second pins 24 and The reservoir 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 . In this way, by providing the storage portion 45 in a region unevenly distributed on the first pin 14 side on the upper surface of the second pin 24 , the grease 60 stored in the storage portion 45 is gradually removed from the sliding slit 41 side over time. to be supplied to

The second pin 24 shown in FIGS. 8 to 11 has an arc-shaped curved surface facing the first pin 14 that moves along the sliding slit 41 in a cross-sectional view. A storage portion 45 is provided at a corner of the upper surface of the upper surface region on the sliding slit 41 side with respect to the upper end of the curved surface. As shown in FIG. 10, the second pin 24 is provided with a recess-shaped storage portion 45 by cutting the upper surface corner in the extension direction of the second pin 24 . The storage portion 45 shown in the figure has a groove shape with a concave center in cross section, and has a curved bottom surface that gradually becomes deeper toward the center portion. The reservoir 45 of this shape can be easily machined. However, the reservoir can also be formed in a V-shaped, U-shaped, or U-shaped groove shape when viewed in cross section.

By widening the width of the surface of the second pin 24 and deepening the depth of the storage portion 45 , the volume of the storage portion 45 can be increased and a large amount of grease 60 can be stored. However, cutting the surface of the metal pin widely and deeply reduces the strength of the metal pin. Therefore, the width (W) and cutting depth (H) of the reservoir 45 are determined to be optimum width (W) and depth (H) in consideration of the amount of grease 60 accumulated and the strength of the metal pin. . The storage portion 45 has a lateral width (W) of, for example, 20 to 100% of the curvature radius r of the curved surface of the second pin 24 (corresponding to the radius r in the cylindrical second pin 24), preferably 30 to 80%. %, more preferably 40 to 60%, and the depth (H) is 3 to 30%, preferably 5 to 25%, more preferably 10 to 20% of the radius of curvature r of the curved surface of the second pin 24. do. As shown in the figure, in the second pin 24 having the reservoir 45, the surface is cut to a predetermined depth (H) to form the reservoir 45, so at least the cut depth (H) It is possible to store the grease 60 having a thickness equal to or larger than the film thickness corresponding to H).

Furthermore, the storage portion 45 is formed on the top surface side of the second pin 24 and at the corner of the top surface on the sliding slit 41 side. The amount of grease 60 stored and the degree of supply to the contact area 42 are also affected by the positional relationship. In the cross-sectional view shown in FIG. 11, the storage portion 45 has a storage amount of the grease 60 and a contact area 42 depending on the magnitude of the positioning angle (θ) formed by the diameter passing through the midpoint of the width (W) and the center line m. You can adjust the degree of supply to For example, when the positioning angle (θ) of the storage portion 45 is increased to approach 90 degrees, the opening of the storage portion 45 faces upward, and the amount of stored grease 60 can be increased. Supply to the area 42 becomes difficult. Conversely, if the positioning angle (θ) is made smaller, the opening of the reservoir 45 approaches the sideways, so the amount of grease 60 that is reserved decreases. Also, if the positioning angle (θ) is too small, the supply speed of the grease 60 from the reservoir 45 to the contact area 42 increases, making it difficult to supply an appropriate amount of grease 60 over a long period of time. Therefore, the magnitude of the positioning angle (θ) for specifying the opening position of the storage portion 45 depends on the storage amount of the grease 60, the supply speed to the contact area 42, the viscosity of the grease 60, and the opening width (W) of the storage portion 45. , depth (H), etc., and is adjusted to an optimum angle. 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, more preferably 40 to 60 degrees. The illustrated reservoir 45 has a positioning angle (θ) of about 50 degrees.

Storing portions 45 formed at the opposing upper surface corners of the pair of second pins 24 are arranged parallel to each other and formed along the sliding slits 41 as shown in FIG. 10 . Here, the length (L) of the storage portion 57 formed in the extension direction of the second pin 24 is the range of the movement locus of the first pin 14 sliding on the pair of second pins 24. I'm trying As a result, the storing portion 45 is arranged so as to cover the entire movement range of the first pin 14 and the second pin 24 that slide against each other. However, the length (L) of the storage portion 45 can be made shorter or longer than the movement range of the first pin 14 .

As shown in FIGS. 10 and 11 , the storage portion 45 formed in the extending direction of the second pin 24 has a uniform width (W), and has both edges cut into an arc shape in plan view. The shape in plan view is an oval shape. Further, the storing portion 45 may have a rectangular shape in plan view, with both edges linear in plan view. Further, the storage part has a curved or linear shape with both edges moving downward in plan view, or a curved or linear shape with both edges moving upward in plan view. can also be trapezoidal.

As described above, the storage portion 45 having a shape that equalizes the overall width (W) can evenly store the grease 60 and evenly supply the stored grease 60 against loss of the grease 60 . However, the storage portion 45 can be cut with various widths (W). For example, although not shown, the storage part can have a central portion with a wider width than 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 have a width of the central portion narrower than that of both end portions. In the reservoir of this structure, the capacity of the reservoir can be increased while reducing the decrease in 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 is long.

As described above, the structure in which the second pin 24 is provided with the storage portion 45 ensures that even when the grease 60 applied to the contact area 42 of the first pin 14 and the second pin 24 disappears over time, the contact area 45 is New grease 60 can be supplied from the reservoir 45 . In this way, the second pins 24 that can store the grease 60 in the storage portion 45 can sequentially supply the grease 60 that disappears over time, so that the first pins 14 and the second pins 24 are directly connected over a long period of time. By preventing them from coming into contact with each other, they can be effectively prevented from wearing each other.

Furthermore, FIG. 9 is an enlarged view of a state in which the first rotating body 10 and the second rotating body 20 have rotated from the state shown in FIG. showing. As shown in this figure, in a state in which the first pin 14 is tilted with respect to the second pin 24, the outer peripheral surface of the tilted first pin 14 is larger than the vertical state shown in FIG. As a result, the gap (d1, d2) between the first pin 14 and the second pin 24 narrows. Thus, even in a state where 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 is 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 columnar shape was explained, but in the present invention, the shape of the first pin and the second pin does not necessarily have to be columnar. It is sufficient that the first pin and the second pin have a shape that facilitates sliding on the contact interface. Typically, at least the contact interface between the first pin and the second pin is curved. In particular, in the example shown in FIG. 8, the first pin 14 and the second pin 24 have circular end surfaces and are configured to be in contact with each other at their cylindrical side surfaces. Instead, it may be an ellipse or a curved surface. In this specification, such a partially curved shape is called a pin for convenience.

For example, as shown in FIGS. 12 and 13, the pair of second pins 24 may have curved surfaces facing each other and flat or prismatic portions at other portions. 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 curved, and the top and bottom are flat. In the second pin 24 having the shape shown in FIGS. 12 and 13 as well, a storage portion for storing the grease 60 is provided above the contact region 42 with the first pin 14 and in the upper surface region facing the first pin 14. 45 is provided. The pair of second pins 24 shown in FIGS. 12 and 13 also has an arc-shaped curved surface facing the first pin 14 that moves along the sliding slit 41, and the upper surface side of this curved surface A storage portion 45 is provided at a corner portion of the upper surface facing the upper surface area on the side of the sliding slit 41 from the upper end of the curved surface as an upper surface corner portion. The second pin 24 is provided with recess-shaped reservoirs 45 by cutting in the extension direction of the second pin 24 at opposing top corners.

Moreover, although the example which comprised the pair of 2nd pin 24 by the separate member was demonstrated in embodiment mentioned above, you may integrally shape|mold a pair of 2nd pin. In the example shown in FIG. 12, a pair of second pins 24 are formed in a U-shape in plan view by cutting a metal block. With this configuration, the heat capacity of the second pin 24 can be increased, and the heat generated by the friction with the first pin 14 can be easily absorbed. In addition, the heat conduction of the second pin 24 is improved, the heat dissipation is improved, the deterioration due to friction with the first pin 14 is suppressed, and the service life and reliability are further improved.

(Another example of rotation transmission mechanism)
In the component supply devices 100 and 200 of the above-described embodiments, as the rotation transmission mechanism 4, the first rotating body 10 has a first pin protruding parallel to the first rotating shaft 11 in a region other than the first rotating shaft 11. 14, and the second rotating body 20 has a pair of second pins 24 that guide the first pin 14 therebetween in an attitude toward the second rotation shaft 21. However, the rotation transmission mechanism 4 includes: As shown in FIGS. 14 to 18, a pair of first rotating bodies 10 are fixed to the first rotating body 10 in a posture protruding 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 reference numerals are given to the same components as in the above-described embodiment, and detailed description thereof will be omitted.

14 to 18, the rotation transmission mechanism 4 of the component feeding device 300 shown in Figs. 14 and the second pin 24 are driven in conjunction with each other. When either the first rotating body 10 or the second rotating body 20 is rotated, the pair of the 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 contacts and interlocks with the first pin 14 within 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 with each other. 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 but inclined at an angle α, the first pin 14 and the second pin 24 are perpendicular to each other. Instead, it slides while changing the contact position while maintaining the tilted posture.

(first pin 14)
The pair of first pins 14 are fixed to a region on the bottom side of the first sub-rotary plate 15 and on the outer peripheral side away from the first rotating shaft 11 . The pair of first pins 14 are arranged along a circumferential orbit around the first rotation shaft 11 with a predetermined distance therebetween. A pair of first pins 14 shown in the drawing are arranged parallel to the first rotating shaft 11 and protrude toward the bottom surface of the first rotating body 10 .

(second pin 24)
The second pin 24 is fixed in a posture protruding toward the center of the second rotating 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 plan view. As a result, the first pin 14 and the second pin 24 intersect with each other when the first sub-rotary plate 15 is set in the second opening 26 . When the first rotating body 10 and the second rotating body 20 rotate, the first pin 14 slides around the second pin 24 . When 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 pins 14 and the second pins 24 so as to allow the first pins 14 and the second pins 24 to slide while being inclined.

14 to 18, the clearance provided between each first pin 14 and second pin 24 can be made smaller than the clearance in the rotation transmission mechanism 4 described above. can. 14 to 18, the pair of first pins 14 inclined in the vertical plane are replaced by the circular second pins 24, as shown in FIG. This is because the tilting 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 arranged along the rotational orbit of the first rotor arranged in an inclined attitude with respect to the second rotor 20 on which the second pins 24 are arranged. Since it rotates, the rotational trajectory of the pair of first pins 14 is elliptical with respect to the rotational trajectory of the second pin 24 . Therefore, the second pin 24 that moves in the sliding gap between the pair of first pins 14 has a section where it slides in a slightly inclined posture 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 the first pin 14 and the second pin 24 can be rotationally driven while interlocking reasonably.

As shown in FIG. 18, the gaps (d1, d2) formed between the pair of first pins 14 and second pins 24 allow the second pins 24 to move between the first pins 14 while changing the angle of inclination. You can smoothly move up and down. In order to form the gaps (d1, d2), the gap between the pair of first pins 14 is formed larger than the diameter of the second pin 24. As shown in FIG. Further, by arranging the second pin 24 so that its center coincides with the center of the interval 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 area 42 between 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 aforementioned NLGI No. 0 to No. No. 3 chassis grease, lithium grease, lithium grease containing molybdenum, etc. can be used.

(Storage unit 45)
The second pin 24 guided by the pair of first pins 14 stores 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 retained. is provided. The second pin 24 shown in FIGS. 17 and 18 is provided with a storage portion 45 for storing grease 60 in an upper surface area facing the first pin 14 and above the contact area 42 . Here, the upper surface region facing the first pin 14 means the upper surface of the second pin 24 and the region facing the first pins 14 located on both sides. Therefore, as shown in FIG. 18, when the second pin 24 has a cylindrical shape with a circular cross section, a pair of symmetrical rods are arranged on both sides of a vertical line n passing through the center of the second pin 24 . A reservoir 45 is formed. By providing a pair of storage portions 45 on both sides of the upper surface of the second pin 24 in this manner, the grease 60 stored in the storage portions 45 is supplied to the sliding slit 41 side over time. I'm trying to

The second pin 24 that moves in the sliding slit 41 has an arc-shaped curved surface facing the pair of first pins 14 in a cross-sectional view. A storage portion 45 is provided in the upper surface corner portion of the upper surface area on the side of the first pin from the upper end of the . That is, the columnar second pin 24 is provided with recessed storage portions 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 capacity of this storage portion 45 can also be adjusted by adjusting the width and depth of the recess formed by cutting the surface of the second pin 24 in the same manner as described above. A 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 the length (L) of the pair of first pins 14 is set to be within the range of the movement trajectory of Thereby, the entire movement range of the first pin 14 and the second pin 24 that slide against each other can be covered. However, the length (L) of the storage portion 45 can be made shorter or longer than the movement range of the first pin 14 . The storage portion 45 formed in the extending direction of the second pin 24 may have a uniform width (W) and may have an oval shape or a rectangular shape in plan view, as described above. , or may be trapezoidal.

As described above, the storage portion 45 having a shape that equalizes the overall width (W) can evenly store the grease 60 and evenly supply the stored grease 60 against loss of the grease 60 . However, the storage portion 45 can be cut with various widths (W). For example, although not shown, the storage part can have a central portion with a wider width than 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 in which the storage portions 45 are provided 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 second pin 24 disappears over time. Also in this case, new grease 60 can be supplied to this region from the reservoir 45 . In this way, the second pin 24 that can store the grease 60 in the storage portion 45 can sequentially supply the grease 60 that disappears over time, so that the pair of the first pin 14 and the second pin 24 can be held together for a long period of time. are prevented from coming into direct contact with each other, effectively preventing them from coming into contact with each other and being worn.

The component supply apparatuses 100 , 200 , and 300 described above have the outer peripheral wall 51 arranged along the outer peripheral edge of the second rotor 20 . The second rotating body 20 having the outer peripheral wall 51 can prevent the parts P from jumping out of the second rotating body 20 and falling due to centrifugal force by increasing the rotation speed. Therefore, the component supply apparatuses 100, 200, and 300 can rotate the second rotating body 20 rapidly and discharge a large amount of components P per unit time. However, the outer peripheral wall does not necessarily have to be provided. This is because in the component supply device 100 that rotates the second rotating body 20 slowly, the component P placed on the second rotating body 20 does not drop outward due to acceleration.

Furthermore, the component supply apparatuses 100, 200, and 300 described above can be provided with a mechanism for sorting out the components P transferred by the second rotating body 20 according to the purpose, or for aligning and carrying out the components. The component supply device 100 shown in FIG. 1 has a mechanism for aligning a large number of components P to be transported on the transport surface 20A of the second rotating body 20 in a row, arranging them in the transport direction, and carrying them out. there is The component supply device 100 of FIG. 1 includes a destacking unit 32 that eliminates overlapping of the components P transferred by the second rotating body 20, a line guide 33 that arranges the components P transferred by the outer ring plate 2 in a line, A sorting mechanism 34 for sorting the posture of the parts P to be transferred is provided. The component supply apparatuses 100, 200, and 300 pass the components P supplied from the first rotating body 10 to the second rotating body 20 through the destacking section 32 to make one row, and further pass through the one-row guide 33 to make one row. Transfer to 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 direction 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 the parts in the normal posture to pass through the outer ring plate 2 without dropping them, and discharges them to the outside.

The illustrated component supply device 100 has a sorting guide 34A as the sorting mechanism 34 at the ascending portion 6 of the second rotating body 20 . However, in the parts supply device, the mechanism for sorting out and aligning the parts transferred by the second rotating body is not specified as the above mechanism. The parts to be transported are sorted into a desired state by various mechanisms according to their types and shapes, and are discharged after being aligned.

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