Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibrating parts feeder, and more particularly to a vibrating parts feeder having a simplified mechanism for collapsing parts transferred in a state where trucks are stacked.

[0002]

2. Description of the Related Art A vibrating parts feeder is often used to feed parts to a next process in a predetermined posture or orientation. However, the parts transferred from the bottom of the bowl of the vibrating parts feeder are usually stacked. In the middle of the track, a mechanism for breaking down the components forming two or more layers to form a layer, preferably a single layer, is attached. FIG. 16 is a perspective view of the layer collapse portion 131 formed on the track in the bowl of the conventional vibrating parts feeder. That is, the part P is the peripheral wall 1 of the bowl 121.
The track 124 formed along the inner peripheral surface of the carriage 23 is transferred in the direction indicated by the arrow. The part P is formed by the centrifugal force component of the transfer force received by the torsional vibration of the vibrating part feeder, and the track 124 is formed to be inclined slightly downward toward the outer diameter of the bowl 121. Will be transferred along.

The layer collapse portion 131 in the middle of the track 124 is formed as follows. A structure in which a layer breaking plate 132 is fitted to a position where the peripheral wall 123 is cut to a surface of the track 124 with a predetermined length, and the inner peripheral surface is fixed to the bowl 121 by a bolt 133b together with a retaining block 133 aligned with the peripheral wall 123. Has been done. Then, the layer collapsing plate 132 is made slightly thinner than the thickness of the component P, and the end surface 132e is aligned with the inner peripheral surface of the peripheral wall 123 on the upstream side.
On the downstream side, it is shaped so as to project in a taper shape onto the track 124.

When the parts P that are transferred from the upstream side in a stacked state form the layer collapse portion 131, the lowest part P that is in contact with the surface of the track 124 is the end surface 132e of the layer collapse plate 132. Along the inner peripheral side of the peripheral wall 123, the component P of the second layer or more is transferred to the layer collapsing plate 132 along the inner peripheral surface of the peripheral wall 123, and is dropped to the track 124 from the downstream end thereof. In this way, the overlapping of the parts P is broken.

An electromagnet 16 wound with a coil 15 is encapsulated and embedded in the fixed block 14 together with a resin 16r, and the electromagnet 16 is opposed to a movable core 12c provided on the lower surface of the movable block 12 with a slight gap. There is. Further, the fixed block 14 is engaged with the base block 17 by the height adjusting ring 14h, and the base block 17 is installed on the base plate 19 via the anti-vibration rubber 18.

With reference to FIG. 2, in the bowl 21, a flat plate-shaped track 24 having a starting point 24s is formed on the bottom surface 22 in which the part P is accommodated so as to rise spirally along the peripheral wall 23. It serves as a transfer path for the cage component P. The track 24 is formed at an inclination angle of 10 degrees downward toward the outside of the bowl 21. Immediately downstream of the starting point 24s of the truck 24, notches 25A and 25B for narrowing the width of the truck 24 are formed. The part P that spreads to the full width of the truck 24 and is excessively transferred is dropped to the bottom surface. It is supposed to return to 22.

Referring to FIGS. 3 and 4, the parts P are transferred from the right side in a state where the tracks 24 are arranged in multiple rows and stacked, but the width of the tracks 24 is narrowed by the notch 31. The part P on the inner peripheral side falls to the notch 31 and is removed, and the part P on the outer peripheral side collapses into the layer collapse groove 33.
Is fed to the upstream end of the. That is, the upstream end portion of the layer collapse groove 33 is the outer peripheral side of the track 24,
It is provided in the vicinity of the inner peripheral surface of the peripheral wall 23, and the downstream end is formed so as to be obliquely intersected with the track 24 so as to be on the inner peripheral side of the track 24. The width is set so that one component P can be fitted with a margin. Also referring to FIG. 5, the depth is the deepest at the upstream end and 0.3 mm on the outer peripheral side, and is gradually shallowed toward the downstream side, and disappears so as to unite with the track 24 at the downstream end.

The boat bottom shape of the cross section is maintained. The end mill E is further moved to the inner peripheral side to be shallower in depth, but since the track 24 is slightly inclined downward toward the radially outer side of the bowl 21, the layer collapse groove 33 is moved from the outer peripheral side to the central portion. The sloping slope 33a directed downward gradually disappears, and the entire width becomes narrower. Further, referring to FIG. 6C, by separating the end mill E upward from the surface of the track 24, the downstream end of the layer collapse groove 33 is formed.

The part hangs up to just above the part P to be transferred on the discharge truck 74. And
The lower end surface of the restraining plate 77 is cut in parallel with the discharge truck 74 at an inclination of 10 degrees. Further, the discharge truck 74 is provided with ridge width portions 74n narrowed by the notches 75A and 75B to a width of 0.7 mm at two places on the way, so that the laterally-oriented component P whose center of gravity is displaced falls off. Has become.

Similarly, [15]-[15] in FIG.
With reference to FIG. 15 which is a cross-sectional view taken along the line, the surface of the discharge truck 74 is twisted to be horizontal, the guide block 78 is placed on the inner peripheral side thereof, and the guide block 78 is cut sideways. With the bolt 78b that passes through the notch hole 78h, the discharge truck 74
The width is set to be adjustable within a range of 1 to 1.5 mm, but in the present embodiment, the width is set to 1 mm, and at the same time, the lower end surface of the pressing plate 77 is horizontal, and as described above. The height from the surface of the discharge truck 74 is 0.5 to 1.5 m
It can be adjusted within the range of m, but in the present embodiment, it is 1 m.
It is supposed to be m. That is, the part P has a width of 1 mm on the periphery,
Surrounded by a tunnel having a height of 1 mm, the discharge truck 74 is transferred and discharged from the downstream end without disturbing the direction and posture of the transfer.

The vibrating parts feeder 1 of the present embodiment is constructed as described above, and its operation will be described next.

With reference to FIGS. 1 and 2, a large number of parts P are accommodated on the bottom surface 22 of the bowl 21 of the vibrating parts feeder 1 (shown in a scattered manner in FIG. 2), and the drive unit 11 is provided.
It is assumed that the coil 15 is energized with an alternating current to impart a counterclockwise torsional vibration to the bowl 21 when viewed from above. The stacked parts P and the individual parts P are moved to the peripheral portion of the bottom surface 22 and transferred in the direction indicated by the arrow m,
From the starting point 24s, the user rides on the truck 24 and is spirally raised along the peripheral wall 23. Immediately the part P is notched 25
At A, the part P on the inner peripheral side of the track 24 falls into the notch 25A and is returned to the bottom surface 22 of the bowl 21.
Further, if there is a part P that has passed through the track 24 on the outer peripheral side of the notch 25A and spreads in the width direction of the track 24, the part P similarly drops into the subsequent notch 25B and falls in the bowl 21. It is returned to the bottom surface 22. In this way, the transfer amount of the component P is adjusted.

Next, the part P is provided with the notch 3 in the layer collapse portion 30.
1A, referring to FIGS. 3 and 4, the part P on the inner peripheral side of the track 24 falls into the notch 31A and is returned to the bottom surface 22 of the bowl 21. The layer breaking groove 33A is formed on the peripheral wall 23.
Since it is formed in the vicinity of, the parts P transferred on the outer peripheral side of the track 24 are all fitted into the layer collapse groove 33A.
Since the depth of the upstream end of the layer collapse groove 33A is 0.3 mm on the outer peripheral side thereof, in the case of the component P stacked in two or three layers, the lowermost component P is located in the layer collapse groove 33A. The part P of the second layer or more, which is guided and transferred to the inner peripheral side, but is not bound by the layer collapse groove 33A, is separated from the lowermost part P by the torsional vibration received, and the layer collapse groove 33 is formed.
It will be transferred to the track 24 on the outer peripheral side of A and will be transferred along the peripheral wall 23. In this way, the layers of the stacked components P are collapsed. The component P transferred along the layer collapse groove 33A moves to the outer peripheral side of the track 24 and is transferred as the layer collapse groove 33A disappears.

Then, in case the layer collapse is insufficient with only the layer collapse groove 33A, a unit including the notch 31B and the layer collapse groove 33B and the notch 31 as shown in FIG.
A unit including C and the layer breaking groove 33C is formed in series. These layer breaking grooves 33B and layer breaking grooves 33C
Since the action of the layer collapse due to is similar to that of the layer collapse groove 33A, the description thereof will be omitted. Taking the case where the parts P are overlapped in three layers as an example, the layers P are broken into the lowest one layer and the upper two layers in the layer breaking groove 33A, and then the upper two layers P of the parts P are broken. It is broken into a single layer. In addition, the notch 31B and the notch 31C are both provided on the upstream side of the layer collapse groove 33.
After being guided to the inner peripheral side by A or the layer breaking groove 33B, the component P that does not sufficiently return to the outer peripheral side is dropped and returned to the bottom surface 22.

The part P that has passed through the layer breaking portion 30 reaches the quick-discharging gate 40 shown in FIG. 7, but the quick-discharging gate 40 is not used in a steady state, and the part P is convex toward the track 24 side. It is transferred along the side surface of the columnar gate block 44 that projects. In the unsteady state, in FIG. 2, the gate block 44 is rotated in the counterclockwise direction together with the rotating plate 43 around the shaft provided with the knob screw 42, and the part P is taken out to the notch portion 41.

The parts P that have passed through the rapid delivery gate 40 are made into a single row by the track 24 whose width is narrowed by the notch 51A, and then, as shown in FIG.
The part P indicated by the solid line above drops on the step 52 and falls on the alignment part 50.
The alignment groove 53 is moved to the circular gutter portion 55 as indicated by the alternate long and short dash line. At this time, the part P whose length direction is oblique or orthogonal to the alignment groove 53 is in the direction in which the center of gravity is the lowest in the round gutter portion 55 during transfer, that is, the length direction is in the direction of the alignment groove 53. I will turn it. Further, as shown in FIG. 10, the part P indicated by the solid line is transferred from the downstream end of the alignment groove 53 to the alignment groove 57 obliquely intersecting with the part P indicated by the one-dot chain line by dropping the step 56. However, at this time, if there is a part P in which the transfer direction is not yet sufficiently aligned in the upstream side alignment groove 53, it is transferred to the downstream end of the alignment groove 57 while the transfer direction is adjusted.

Next, the parts P are arranged from the aligning section 50 to the single row forming section 6
11, the component P is moved from the downstream end of the alignment groove 57 to the transition surface 62, and is formed by cutting out the inner peripheral side of the transition surface 62 with reference to FIG. Width 1
The mm single row track 64 is transported in a single row along its sidewall 63. At this time, the width of the single track 64 is 1 m
Since it is m, a horizontally oriented part P is also included. When the parts P are arranged in multiple rows, the parts P on the inner peripheral side pass through the inclined surface 65 and drop to the flat surface 66, and one round down from the notch 67 formed in the flat surface 66 or from the downstream end of the flat surface 66. It is returned to the truck 24.

Further, referring to FIGS. 13 and 14, the part P
Is a linear discharge portion 70 from the downstream end of the single-row truck 64.
Is transferred to the discharge track 74 having a width of 1 mm following the transition surface 72 inclined at 10 degrees, and the wiper 76 is provided immediately above the discharge track 74 with a gap so that the component P can pass only in a single layer. In the discharge truck 74 on the downstream side of the wiper 76, the component P is formed into a single layer and is transferred while being prevented from overlapping by the lower end surface of the pressing plate 77 inclined at 10 degrees. Further, the discharge truck 74 has a narrow portion 7 narrowed to 0.7 mm by the notches 75A and 75B.
Since 4n is formed, the laterally oriented portion P has its center of gravity deviated and falls into the notch 75A or 75B to be eliminated. After that, referring to FIGS. 13 and 15, the part P having the lengthwise direction as the transfer direction is formed into a tunnel shape by the vertical side wall 73, the holding plate 77 having the lower end surface leveled, and the holding block 78. The posture is maintained by the discharged discharge truck 74, and the discharge truck 74 discharges it from the downstream end. And
In this embodiment, since the discharge track 74 is formed in a straight line, the cost is lower than that in the case of forming it in a curved line, and the parts P are discharged in a single layer or in a single row. However, it progresses extremely smoothly.

The vibrating parts feeder 1 of the present embodiment is constructed and operates as described above, but of course, the present invention is not limited to this, and various modifications can be made based on the technical idea of the present invention. is there.

For example, in the present embodiment, the component is described as a recumbent prismatic component P, but it may be a prismatic shape, a prismatic cylinder shape, a cylindrical shape, a cylindrical shape, or a rectangular or circular flat plate shape in a standing posture. Even parts can break up in stacking as well. If the bottom of the part is polygonal or disk-shaped,
The term “longitudinal direction” as used in claim 1 means the maximum diameter or the diameter thereof. Of course, in these cases, it is needless to say that a mechanism for aligning, arranging a single row, or the like needs a mechanism corresponding to the shape.

Further, in the present embodiment, the layer breaking groove 3
The feeding of the prismatic portion P having a width of 0.8 mm, a thickness of 0.8 mm and a length of 1.6 mm by the vibrating parts feeder 1 including 3A, 33B and 33C has been described.

Although it is provided in the vicinity of 3, the component P is fitted in the layer collapse grooves 33A, 33B, 33C even if the peripheral wall 23 is provided with a width smaller than one width or a thickness of the component P. Put in.

Further, in the present embodiment, the notch 31
Although three units are formed such that the layer A is formed by the groove 33A, four or more units may be provided, and one or two units may be provided for a component in which stacked components can be easily destroyed.

Further, in this embodiment, the layer breaking groove 3 is used.
Although the width of 3 is set so that the component P can be fitted in a single row with a margin, the width of the layer collapse groove 33 is larger than this, for example, the component P is 2
Even if the width is such that the parts fit in rows, the part P of the second layer or more is sufficiently separated from the part P of the lowermost layer.

Further, in the present embodiment, the notch 31
A unit consisting of A and the layer breaking groove 33A is provided in series, but three units are arranged at equal angles, for example, to substitute a wiper, and an alignment mechanism and a sorting mechanism are provided between them. It may be installed.

Further, in the present embodiment, the track 2
Although 4 is inclined slightly downward toward the outside of the bowl 21, the track may be horizontal.

Claims (5)

(57) [Claims] 1. A prismatic shape, a prismatic shape, a cylindrical shape, a cylindrical shape, in which tracks in a bowl are stacked and transferred.
Alternatively, in a vibrating parts feeder including a mechanism for breaking a flat-plate-shaped component such as a square or a circle, the mechanism has a position close to the inner peripheral surface of the peripheral wall of the truck as an upstream end, and The depth is shallower than the thickness, and the width of the parts whose lengthwise direction is approximately the direction of transfer is such that the parts can be fitted in a single row with a margin. The depth is gradually reduced and the downstream end is a layer collapse groove that is united with the track, and the single part and the bottom layer part of the stacked parts are guided to the layer collapse groove and the inner circumference The vibrating parts feeder characterized in that the second layer or more of the stacked components transferred to the side are separated into the tracks on the outer peripheral side of the layer breaking groove by the transfer force of the torsional vibration. 2. The vibrating part feeder according to claim 1, wherein a plurality of the layer breaking grooves are formed in series on the track. 3. A notch for narrowing the width of the track, leaving the outer peripheral side of the track, is formed immediately upstream of the layer collapse groove so as to feed a component to the upstream end of the layer collapse groove. The vibrating parts feeder according to claim 1 or claim 2. 4. The vibrating part feeder according to claim 1, wherein the layer breaking groove is formed by cutting the track with an end mill. 5. A prismatic shape, a prismatic shape, a cylindrical shape, a cylindrical shape, which are transferred by stacking tracks in a bowl.
Or, the formation of the layer breaking groove formed in the track for breaking a flat plate-shaped part such as a square shape or a circle shape causes the end mill to have a circumferential end close to the inner circumferential surface of the circumferential wall of the track. After setting and lowering, the tip surface is dug down from the surface of the track to a depth shallower than the thickness of the component, and then the end mill is moved obliquely with respect to the transfer direction of the track toward the inner peripheral side. The method for processing a layer breaking groove, which is performed by gradually decreasing the depth of the front end surface and raising the depth to the level of the surface of the track.
