Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component supplying apparatus for aligning and supplying relatively small rectangular or cylindrical components such as chip components for electronic circuits.

[0002]

2. Description of the Related Art In a continuous production line, the supply capacity of a component supply apparatus which arranges components in a bulk state and supplies them one by one often greatly affects the productivity of the entire line. There are various types of component supply devices, such as a vibration type and a rotating disk type, but a relatively small component supply device such as an electronic circuit chip-shaped component requires particularly high supply capability. Therefore, a rotating disk system is suitable, in which there are few troubles even at high speed operation, and vibration and noise are hardly increased.

An example of such a rotating disk type component supply apparatus is disclosed in Japanese Patent Publication No. 57-24286. The component supply device includes a tilting ring that rotates around an inclined axis, a driving disk that is inscribed in the tilting ring at the lowest rotation position of the tilting ring, and that rotates horizontally, and an outer periphery of the tilting ring. A part to be put on the upper surface of the base disk is provided at a contact portion between the base disk and the tilt ring from the outer peripheral side of the disk. While being moved along the alignment wall by the rotation of the tilting ring, aligned in a predetermined posture by an alignment mechanism such as a groove provided in the alignment wall, and moved to a predetermined position. It is sent from the outlet to the supply chute. In addition, components in a posture unsuitable for supply fall from the inner peripheral side of the tilting ring onto the base disk.

[0004]

In the above-described component supply device, since the alignment wall is fixed, the part feeding device is pressed against the alignment wall by centrifugal force and the alignment between the component and the alignment wall is performed. Has a problem in that a frictional force acts on the, and the component conveying speed is reduced as compared with the rotation speed of the tilt ring. In addition, when the tilt ring is rotated at a high speed, the rebound when the part collides with the edge of the groove or the projection, which is the aligning mechanism of the aligning wall, becomes large, and the base is not aligned in a predetermined posture. Since the number of components falling on the moving disk increases and the efficiency of alignment decreases, the component supply capacity does not always increase in proportion to the rotation speed of the tilt ring.

It is an object of the present invention to provide a component supply apparatus capable of efficiently arranging components and having a high supply capability.

[0006]

In order to solve the above-mentioned problems, a component supply device according to the present invention has an outer ring that rotates horizontally, and a rotating shaft disposed inside the outer ring and inclined at a predetermined angle. Interpolate between the disk and the inner peripheral surface of the outer ring and the outer peripheral surface of the disk, so that the upper end surface intersects the upper surface of the disk up and down in the circumferential direction in a direction opposite to the rotation axis of the disk. An inner ring having a rotation axis inclined to the outer ring, the outer ring, the disk and the inner ring are rotated in the same direction, and the components to be put on the upper surface of the disk are moved from the disk outer peripheral side to the upper end surface of the inner ring. The upper ring is introduced into a partial annular groove formed by the inner peripheral surface of the outer ring, the outer peripheral surface of the disk, and the upper end surface of the inner ring, and is discharged from the highest rotation position of the upper end surface of the inner ring. Than is adopted a configuration in which is supplied to the.

That is, the upper end surface of the inner ring interpolating between the inner peripheral surface of the horizontally rotating outer ring and the outer peripheral surface of the disk having the inclined rotation axis crosses the upper surface of the disk up and down in the circumferential direction. By rotating the outer ring, the disk and the inner ring in the same direction, the parts to be put on the upper surface of the disk can be mounted on the outer ring with a small speed difference by rotating the outer ring, the disk and the inner ring in the same direction. In order to be able to efficiently align by introducing into the partial annular groove formed by the inner peripheral surface, the disk outer peripheral surface and the inner ring upper end surface, and to be able to supply to the discharge end at a transport speed almost equal to the rotation speed of the outer ring. It was done.

The distance between the inner peripheral surface of the outer ring and the outer peripheral surface of the disk is made substantially equal to the width of one component, and the components are aligned in a line when the components are introduced into the partial annular groove. Means may be provided in the part conveying path from the partial annular groove to the discharge end to exclude parts that are stacked in two or more layers in the partial annular groove, so that the parts can be aligned in one layer.

By guiding the outer ring and the inner ring, and the inner ring and the disk with spherical surfaces having the same center point, respectively, even during high-speed operation,
The outer ring and the inner ring, and the inner ring and the disk can be reliably guided with a predetermined gap to prevent generation of vibration and noise.

By making the rotation speed of the outer ring faster than the rotation speed of the inner ring, the components which are conveyed while being pressed against the inner peripheral surface of the outer ring by the centrifugal force on the upper end surface of the inner ring are: By applying a frictional force so that the longitudinal direction is directed to the circumferential direction of the device, the posture of the component can be corrected to a posture suitable for supply. Similarly, by making the rotation speed of the inner ring faster than the rotation speed of the disk, it is possible to correct the posture of the component that is placed on the disk upper surface and conveyed while being pressed against the inner peripheral surface of the inner ring. .

Further, by increasing the rotation speed in the order of the disk, the inner ring and the outer ring toward the outer peripheral side of the apparatus, the parts are placed on both the upper surface of the disk and the upper end surface of the inner ring and pressed against the inner peripheral surface of the outer ring. In this case, the frictional force caused by the difference between the rotational speeds of the disk, the inner ring, and the outer ring is simultaneously applied, so that the posture of the component can be corrected more efficiently.

By arranging the inner ring such that the highest rotational position of the upper end surface thereof is substantially equal to the height of the upper end surface of the outer ring, it is possible to easily supply components to the discharge end.

[0013] By providing a component discharge groove which opens downward facing the upper end surface of the inner ring at the highest rotational position of the upper end surface of the inner ring, the component is released from the highest rotational position of the upper end surface of the inner ring by this component discharge groove. Can be smoothly supplied to the discharge end.

Further, by forming the component discharge groove along the tangential direction of the inner ring, the supply of the component can be made smoother.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. This component supply device is for supplying small components 1 having a rectangular parallelepiped shape in a line in a row in a longitudinal direction. As shown in FIGS. 1 and 2, the component supply device is configured to rotate horizontally around a vertical axis 2a. Ring 2
A disk 3 disposed inside the outer ring 2 and having a rotation axis 3a inclined by 10 degrees with respect to the vertical axis 2a;
It is basically composed of an inner ring 4 provided so as to interpolate between the inner peripheral surface of the outer ring 2 and the outer peripheral surface of the disk 3. Outer ring 2, disk 3 and inner ring 4
The motors 5, 6, and 7 are rotated at a constant rotational speed in the same direction (counterclockwise direction in FIG. 1) by the respective motors 5, 6, and 7. In this order, the speed is gradually increased toward the outer peripheral side of the apparatus.

The inner ring 4 has a rotating shaft 4a inclined at 5 degrees in a direction opposite to the disk rotating shaft 3a with respect to the vertical shaft 2a in a plane including the vertical shaft 2a and the rotating shaft 3a of the disk 3.
The upper end face 4b is arranged so as to intersect the upper surface 3b of the disk 3 vertically in the circumferential direction, so that the highest rotational position of the upper end face 4b is substantially equal to the height of the upper end face 2b of the outer ring 2. I have.

The inner peripheral surface and the outer peripheral surface of the upper half of the inner ring 4 are formed as spherical surfaces centering on the point Q in the figure, and the inner peripheral surface of the outer ring 2 sandwiching the upper half of the inner ring 4. Of the disk 3 and the outer peripheral surface of the disk 3 are similarly formed into spherical surfaces with the point Q as the center. That is, the outer ring 2 and the inner ring 4,
The inner ring 4 and the disk 3 are guided by spherical surfaces having the same center point Q, so that the outer ring 2 and the inner ring 4 and the inner ring 4 and the disk 3 can be reliably fixed even during high-speed operation. Guided with no gap, no vibration or noise is generated.

The distance between the inner peripheral surface of the outer ring 2 and the outer peripheral surface of the disk 3 is slightly larger than the width of the component 1, and the inner peripheral surface of the outer ring 2, the outer peripheral surface of the disk 3, and the inner ring The components 1 are introduced into the partial annular groove 8 formed by the upper end surface 4b of the 4 in a line.

At the center of the upper surface 3b of the disk 3, a cylindrical portion 3c is provided upward.
The mounting portion 9a of the guide plate 9 which is bent so that the curvature becomes smaller toward the tip is rotatably fitted around the outer periphery of the guide plate 9.
The guide plate 9 has the tip of a lever 9b provided on its mounting portion 9a connected to a lever stopper 10a of an annular fixed top plate 10 provided above the outer ring 2 by a spring 11, and is mounted on the disk 3. The component 1 is guided in the outer peripheral direction of the disk 3 while rotating according to the load received from the component 1 being conveyed.

A part of the top plate 10 projects to the inner peripheral side, and the top plate 10 opens downward at the maximum rotation position of the inner ring upper end surface 4b so as to face the inner ring upper end surface 4b. The component discharge groove 10b extending along the tangential direction of the inner ring 4 and the discharge groove 10b at the highest rotation position of the inner ring upper end surface 4b are guided to the discharge groove 10b. A guide groove 10c is provided. Thus, the aligned components 1 are smoothly supplied to the outlet of the component discharge groove 10b as a discharge end. The outlet of the discharge groove 10b is continuous with the component transport path 12a of the transport device 12 that sends the components 1 in the aligned state to the next process.

The top plate 10 has an air nozzle 13 for blowing compressed air toward the inner peripheral side of the apparatus immediately before the position where the parts 1 aligned in the partial annular groove 8 are introduced into the guide groove 10c; 13 is provided with an air supply passage 14 for introducing compressed air. When the parts 1 are stacked and transported in two or more layers from the partial annular groove 8, the parts 1 above the second layer are compressed with compressed air. It is blown back and returned to the disk upper surface 3b. In addition, as a means for removing the component 1 above the second layer, a mechanical wiper or the like can be used.

Further, a vertical air nozzle 15 for blowing an air jet downward along the inner peripheral surface of the inner ring 4 is provided in the vicinity of the horizontal air nozzle 13, and the longitudinal direction is in the apparatus circumferential direction. The part 1 not facing is blown down to the disk upper surface 3b by an air jet.

Next, the flow of the component 1 in the component supply device will be described. As shown in the left half of FIGS. 1 and 2, the parts 1 loaded in a bulk state on the side of the upper surface 3b of the disk lower than the upper end surface 4b of the inner ring are firstly rotated by the rotation of the disk 3. While being conveyed clockwise, the disc 3 moves toward the outer peripheral direction by centrifugal force and the guidance of the guide plate 9.

As the disk 3 rises with the rotation and the inner ring 4 descends, as shown in the left half of FIG. 3, the component 1 is moved from the outer periphery of the disk 3 to the upper side of the inner ring 4 by centrifugal force. After being moved onto the end surface 4b and being pressed against the inner peripheral surface of the outer ring 2, it is transported on the upper end surface 4b of the inner ring 4 at substantially the same speed as the outer ring 2.

At this time, since the outer ring 2 is rotating a little faster than the inner ring 4 and the inner ring 4 is rotating a little faster than the disc 3, the part 1 in the upright posture and the longitudinal direction is substantially the radial direction of the device. Most of the components 1 in a position partially resting on the disk upper surface 3b are oriented in the circumferential direction of the apparatus by frictional force acting between the outer ring 2, the inner ring 4 and the disk 3. The posture is corrected so as to be suitable for feeding, and the posture becomes suitable for supply. In the stage before the transfer to the upper end surface 4b of the inner ring 4, a part of the part 1 which is conveyed while being pressed on the inner peripheral surface of the inner ring 4 on the disk upper surface 3b is also replaced with the inner ring 4 and the disk. The posture is corrected by the speed difference of 3.

As shown in the left half of FIG. 4, the disk 1 is further raised, the inner ring 4 is further lowered, and the disk upper surface 3b is moved downward. At a position higher than the inner ring upper end surface 4b,
Outer ring 2 inner peripheral surface, disk 3 outer peripheral surface and inner ring 4
Is introduced into the partial annular groove 8 formed by the upper end surface 4b. At this time, since the width of the partial annular groove 8 is substantially equal to the width of the component 1, the components 1 are oriented in a longitudinal direction in the device circumferential direction or are aligned in a raised posture.

As shown in the right half of FIG.
When the inner ring 4 is at the highest rotation position and the inner ring 4 is at the lowest rotation position, the partial annular groove 8 is deepest, and the parts 1 may be stacked in two or more layers.

The parts 1 aligned with the partial annular grooves 8 are shown in FIG.
As shown in the right half of the figure, the disc 3 is lowered, the inner ring 4 is raised, and even at a position where the partial annular groove 8 is not formed, the disc 3 is transferred on the upper surface 4b of the inner ring 4 in a line.
Of the aligned components 1, those stacked and transported above the second layer and those in the raised position are blown off by the compressed air blown out from the air nozzle 13 and returned to the disk upper surface 3b. In addition, as described above, those whose longitudinal direction is not directed to the apparatus circumferential direction are blown down to the disk upper surface 3b by the downward air jet. This allows
Only the parts 1 whose longitudinal direction is oriented in the circumferential direction of the apparatus are further aligned in a line.

The components 1 arranged in one row in this manner are introduced into the guide grooves 10c of the top plate 10 as the inner ring 4 is further raised, as shown in the right half of FIG. As shown in the left half of FIGS. 1 and 2, the upper end surface 4b of the inner ring 4 is guided by the guide groove 10c.
Is introduced into the component discharge groove 10b at the maximum rotation position, and is supplied from the outlet of the component discharge groove 10b to the transport device 12 to be sent to the next process.

Accordingly, in this component supply device, the component 1 is transported at a speed substantially equal to the rotation speed of the outer ring 2, so that the transport speed is increased in proportion to the speeding up of the device, and the component supply capability is improved. Can be done. Also, since the difference in speed between the surfaces of the partial annular groove 8 for aligning the component 1 is small and the depth of the annular groove 8 changes smoothly, the component 1 can be reliably aligned even if the apparatus is operated at a high speed. Does not decrease efficiency.

In the above-described embodiment, the rotation axis of the disk and the rotation axis of the inner ring are inclined in opposite directions in the same plane as the vertical axis, but are inclined to the opposite sides with respect to the vertical axis. If it is, it is not always necessary to be in the same plane, and the inclination angle can be variously changed. That is, the disc and the inner ring are inclined in substantially opposite directions, but the direction and the inclination angle are not particularly limited.

The rotation speeds of the outer ring, the inner ring, and the disk are higher on the outer peripheral side of the apparatus, but other combinations such as making the three members the same speed may be used.

[0033]

As described above, the component supply apparatus of the present invention includes an inner ring that interpolates between an inner peripheral surface of a horizontally rotating outer ring and an outer peripheral surface of a disk having an inclined rotation axis.
Incline in the direction opposite to the rotation axis of the disk so that its upper end surface crosses the upper surface of the disk up and down in the circumferential direction,
By rotating the outer ring, the disk and the inner ring in the same direction, the components to be put on the upper surface of the disk are introduced into the partial annular groove formed by the inner peripheral surface of the outer ring, the outer peripheral surface of the disk and the upper end surface of the inner ring. Therefore, the components can be efficiently aligned and supplied to the discharge end at high speed, and the productivity of the entire line can be improved.

Further, by rotating the outer ring faster than the inner ring or rotating the inner ring faster than the disk, the parts conveyed while being pressed against the inner peripheral surface of the outer ring or the inner ring can be provided. By applying a frictional force so that the longitudinal direction is directed to the circumferential direction of the apparatus, the posture of the component can be corrected to a posture suitable for supply, and the components can be more efficiently aligned.
