Abstract

PROBLEM TO BE SOLVED: To easily adjust a part aligning means by connecting a movable part for the linear motion of a linear actuator, with the part aligning means formed on a transferring path of parts or its sidewall part, and vertically moving the part aligning means by driving the movable part. SOLUTION: A wiper plate 32 is mounted on a shaft 33 of the linear actuator 31 mounted on the sidewall part 13. As a base 34 of the linear actuator 31 is fixed to the side wall part 13, an armature 35 is attracted to the base 34 against a spring 36 by the magnetic attraction when a coil is energized, a shaft 33 is lowered, and the wiper plate 32 mounted on a lower end of the shaft 33 is also lowered. Accordingly, an interval between a track face 11 and the wiper plate 32 can be reduced, and the armature is returned to the original position held by the spring 36 when the energization to the coil 43 is cut. The interval between the track face 11 and the wiper plate 32 can be easily changed, which prevents the parts 30 from being overlapped and taking the postures except for predetermined posture.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component aligning apparatus for aligning components transferred along a transfer path in a single row, a single layer, or a predetermined posture.

[0002]

2. Description of the Related Art FIG. 18 shows, for example, a vibrating parts feeder 1 as an apparatus for aligning parts. FIG. 19 is a plan view thereof. The bowl 2 having a substantially circular planar shape and having a spiral track 11 formed on its inner peripheral wall as a transfer path for transferring parts is provided by a leaf spring 5 arranged at an equal angular interval to lower the bowl. It is connected to the base block 3. A movable core 4 is integrally attached to the bottom wall of the bowl 2, and faces the electromagnet 7 fixed to the base block 3 with a gap g . The coil 6 is wound around the electromagnet 7. The base block 3 is mounted on the floor S via a cylindrical vibration isolating rubber 8 and a mounting plate 9 mounted on the rubber, and prevents vibration from being transmitted to the floor S. Movable core 4, electromagnet 7, coil 6, leaf spring 5
The torsional vibration drive unit constituted by the above is covered with a cylindrical cover 10.

When an alternating current is applied to the coil 6 wound around the electromagnet 7, an alternating magnetic attraction force is generated between the coil 6 and the movable core 4. Supplied parts are spiral track 1
1 and is discharged from a linear track 12 formed at the discharge end of the track 11 and supplied to the next step. At this time, the parts are arranged in a single row and a single layer, parts other than the predetermined posture are eliminated, or the parts are converted to the predetermined posture by the part alignment means provided in the middle of the truck 11 of the bowl 2. In the next step, only parts having a predetermined posture are supplied.

FIG. 20 shows an example in which a wiper 15 is attached to a side wall 13 of a track 11 as alignment means. The wiper 15 is formed by bending a rectangular flat plate into an L-shape, so that the long portion 15a projects horizontally inward from the side wall portion 13 and is spaced apart from the track surface 11 by a distance H. It is attached to the side wall 13 by 16.

[0005] The truck 11 is inclined downward toward the side wall portion 13, and the cylindrical component 14 is transported while being in contact with the side wall portion 13. The relationship between the diameter D and the height h of the component 14 is D> h. The relationship between the track surface and the interval H between the wiper 15 is D> H and h <H. Therefore, the component 14 transported in the standing posture passes under the wiper 15 as it is, but the component 14 ′ having the peripheral surface in contact with the track surface 11 is caught by the wiper 15 and is dropped from the truck 11. . Also, the overlapping parts of the parts 14 in the standing posture can be removed by the wiper 15, and the parts 14 can be passed through more.

FIG. 21 shows a side plate 17 as an alignment means.
Are arranged on the track surface 11 to form a single row of components. The side plate 17 has a long plate shape, and is disposed on the track so as to gradually narrow the width of the track 11 from the downstream end portion 17a toward the inside in the transport direction A. The downstream end 17a is provided with a screw 2 on the side wall 13.
1 attached. An adjustment plate member 18 having an elongated hole 18a extending in the width direction of the track 11 is fixed above the upstream end portion 17b. Slot 18a
, A hexagon socket screw 22 is inserted through a washer 23. A hexagonal rod spanner is inserted into the hexagonal hole of the hexagonal screw 22 and the hexagonal screw 22 is rotated to screw the screw into the screw hole formed in the fixing piece 19 fixed to the outer peripheral surface of the side wall 13. After tightening, the adjustment plate member 18 is pressed between the washer 23 and the fixing piece 19, and the side plate 17 is pressed.
Is fixed to the side wall 13.

The narrowest track width at the upstream end 17b is slightly larger than the diameter of the round bar-shaped component 20 to be transferred, so that two or more components 20 cannot pass side by side in the width direction. Therefore, when the component 20 is transported in multiple rows (three rows in the drawing) with its axis directed in the transport direction A, the component 20 on the radially inner side is dropped from the track 11 by the gradually narrowing track width. Thus, the components 20 can be sent out in a line in a row.

[0008]

Conventionally, when the type or size of a part to be aligned by the aligning means changes, the aligning means has also been manually adjusted in accordance with the change. For example, in the conventional example shown in FIG. 20, in a component having a height h ′ larger than the height h of the component 14 (the diameter D is the same), h ′ is larger than the distance H between the wiper 15 and the track surface 11. In this case, the part in the standing posture to be passed is caught on the wiper 15. Then, the screw 16 is removed, the wiper 15 is removed from the side wall portion 13, the mounting position of the wiper 15 is raised, and the screw 16 is
To fix it to the side wall 13. This mounting height is set larger than h ′ and smaller than the diameter D,
Only the parts in the standing posture pass through the wiper 15. In addition, a part having a diameter D ′ smaller than the interval H is
Since the parts having the posture to be originally removed also pass through the wiper 15, the interval between the parts and the track surface 11 is adjusted to an optimum value, and the wiper 15 is mounted again. That is, track surface 1
1 is smaller than D 'and larger than the height of the component. In this way, even if the dimensions of the components change, the mounting position of the wiper 15 is manually adjusted so that the components can be properly selected based on the posture.

[0009] In the example shown in FIG.
By loosening the adjustment plate member 18 and sliding it in the width direction of the track 11 along the long hole 18a, thereby adjusting the track width at the upstream end portion 17b of the side plate 17 in accordance with the diameter of the round bar-shaped component 20. Is changing.

As described above, conventionally, the adjustment of the alignment means in accordance with the type and size of the component is performed manually, which requires time and effort.

The present invention has been made in view of the above problems, and has as its object to provide a component aligning apparatus which can easily adjust component aligning means according to the size and type of components.

[0012]

In order to solve the above-mentioned problems, according to the present invention, a linearly-movable movable portion of a linear actuator is connected to a transfer path for transferring a component or to a component alignment means formed on a side wall thereof. . By driving the linear actuator, the component alignment means is moved up and down,
Alternatively, the component is moved left and right with respect to the component transfer direction.

Alternatively, the component arranging means is provided on a plate-shaped bimorph type piezoelectric element in which a metal elastic plate is sandwiched between two rectangular piezoelectric plates, and on one end side of the bimorph type piezoelectric element in the longitudinal direction. And an attached wiper plate. The bimorph type piezoelectric element is disposed with its major axis parallel to the component transfer direction and the flat portion of the piezoelectric plate facing the transfer path surface, and the wiper plate attached to one end of the bimorph type piezoelectric element has a transfer path surface. To form a predetermined distance from the transfer path surface, and the other end of the bimorph type piezoelectric element is fixed to the side wall of the transfer path. Then, by applying a voltage between the piezoelectric plate and the metal elastic plate to bend the bimorph type piezoelectric element, the size of the interval between the wiper plate and the transfer path surface is changed.

Alternatively, the component arranging means is constituted by a plate-shaped bimorph type piezoelectric element which is bonded by sandwiching a metal elastic plate between two piezoelectric plates, and transfers the bimorph type piezoelectric element on a transfer path by moving its plane portion. The bimorph-type piezoelectric element is fixed to the side wall of the transfer path or the transfer path surface at the downstream end with respect to the transfer direction of the bimorph type piezoelectric element. Then, by applying a voltage between the piezoelectric plate and the metal elastic plate to bend the bimorph type piezoelectric element, the width of the transfer path through which the component is transferred is changed.

[0015]

Embodiments of the present invention will be described below with reference to the drawings. Also in the following embodiment, similarly to the conventional example, parts are transferred by a spiral track 11 formed on the bowl 2 of the vibrating parts feeder 1 shown in FIGS.

FIG. 1 shows a first embodiment of the present invention, in which a shaft 33 of a linear actuator 31 attached to a side wall 13 is provided with a wiper plate 32 as a component aligning means.

FIG. 4 is an enlarged perspective view of a partial cross section of the linear actuator 31. As shown in FIG. The linear actuator 31 is a so-called push / pull solenoid, and includes a base 34 in which a coil 43 is wound and an armature 35 to which a shaft 33 is fixed. The armature 35 is supported by the base 34 by forming a gap g with the base 34 by a spring 36.
The armature 35, the shaft 33 and the base 34 are made of a magnetic material. When a direct current is applied to the coil 43, the gap g
A magnetic circuit Φ is formed between the armature 35 and the base 34 which face each other, and the armature 35 and the shaft 33 fixed thereto are sucked into the base 34 at a high speed.

The linear actuator 31
As shown in FIG. 1, the base 34 is
3, when the coil 43 is energized, the armature 35 causes the spring 36
Is attracted to the base 34 against the spring force. Therefore, the shaft 33 descends, and the wiper plate 32 attached to the lower end of the shaft 33 also descends. Therefore,
The distance between the track surface 11 and the wiper plate 32 can be reduced. When the power supply to the coil 43 is cut off, the coil returns to the position held by the spring.

Further, if the linear actuator 31 is mounted upside down from the state shown in the figure and the wiper plate 32 is mounted on the armature 35 with the armature 35 facing downward, 33 and the wiper plate 32 are raised.

That is, the O of the linear actuator 31
By N / OFF, the wiper plate 32 can be moved up and down, and according to the size of the diameter of the columnar part 30 or even if it is changed to another kind of part, according to its size, The distance between the track surface 11 and the wiper plate 32 can be easily changed, and it is possible to surely eliminate overlapping of parts and parts other than a predetermined posture.

Next, FIG. 2 shows a second embodiment of the present invention, in which a movable portion 39 of a linear actuator 37 attached to a side wall portion 13 has a wiper plate 3 as a component aligning means.
2 are installed.

FIG. 5 is a schematic diagram for explaining the operation principle of the linear actuator 37. The linear actuator 37 is a so-called voice coil motor. The linear actuator 37 is provided with a coil 38 such that an electric current flows in a direction perpendicular to the direction of the magnetic field created by the permanent magnet M in a base 38 made of a magnetic material having a permanent magnet M built therein. 44 is provided with a clearance from the base 38 and the permanent magnet M. The coil 44 is connected to, for example, the movable portion 39 that is linearly guided by a ball bearing 45. Coil 4
When a direct current is passed through the coil 4, a thrust based on Fleming's left-hand rule is generated in the coil 44 between the magnetic field formed by the permanent magnet M and the current flowing through the coil 44. Thereby, the coil 44 and the movable part 39 move linearly as shown by the arrow. When the direction of the current is reversed, it moves linearly in the opposite direction.

Such a linear actuator 37 is
As shown in FIG. 2, the base 38 is attached to the side wall portion 13 such that the movable portion 39 moves linearly up and down,
The wiper plate 32 is attached to a lower end of the movable section 39. Therefore, the wiper plate 32 can be moved up or down by passing a current through the coil 44 of the linear actuator 37, and the rise or fall can be selected by selecting the direction of the current. Thus, the track surface 11 and the wiper plate 32 can be easily adjusted according to the size and type of the component.
Can be changed.

FIG. 3 shows a third embodiment of the present invention, in which a wiper plate 32 is attached to one end 41a of a bimorph type piezoelectric element 41 attached to a side wall 13 via an attachment plate 40. Thus, the component arranging means 74 is constituted.

FIG. 8 is a schematic diagram for explaining the operation principle of the bimorph type piezoelectric element 41. The bimorph type piezoelectric element 41 has a structure in which two rectangular piezoelectric plates 50a and 50b are bonded to each other, and has a structure in which a thin metal elastic plate 51 is sandwiched between the piezoelectric plates 50a and 50b. As shown in the figure, a bimorph type piezoelectric element 41 in which the polarization directions P are aligned.
When a positive voltage is applied to the upper and lower piezoelectric plates 50a and 50b and a negative voltage is applied to the central metal elastic plate 51, the upper piezoelectric plate 50a contracts and the lower piezoelectric plate 50b expands.
If one end is fixed, the free end of the other end is bent upward as a whole.

Such a bimorph type piezoelectric element 41 is
As shown in FIG. 3, the long axis is arranged in parallel with the transport direction A, and the flat portion thereof is opposed to the track surface 11. A wiper plate 32 is attached to one end 41 a of the bimorph type piezoelectric element 41 so as to extend toward the track surface 11. The other end 41b is fixed to the side wall 13 via the mounting plate 40.

Therefore, when a DC voltage is applied to the bimorph type piezoelectric element 41, the one end 41a to which the wiper plate 32 is attached is bent and displaced as a free end. Therefore, the distance between the track surface 11 and the wiper plate 32 can be easily changed according to the type and size of the component. Further, since the bimorph type piezoelectric element 41 can continuously change the amount of bending displacement according to the magnitude of the applied voltage, for example, the displacement is detected by a position sensor 42 such as a CCD image sensor. By doing so, the height of the wiper plate 32 can be adjusted more finely.

Next, a fourth embodiment of the present invention will be described. In the present embodiment, an ultrasonic linear motor is used as a linear actuator that moves the wiper plate 32 up and down in each of the above embodiments.

FIG. 6 shows the basic structure of the ultrasonic linear motor 46. Piezoelectric bodies 47, 47 are fixed to the surfaces of the pair of elastic bodies 48, 48, respectively. Elastic bodies 48, 48
A plate-like moving body 49 is provided between the elastic bodies 4.
8, 48 and the moving body 49 are in pressure contact. The operation of the ultrasonic linear motor 46 will be described with reference to FIG. 7. When a high frequency voltage is applied to the piezoelectric body 47 to apply vibration to the surface of the elastic body 48, a traveling wave is generated on the surface of the elastic body 48, and Propagate to Since the moving body 49 is in pressure contact with this surface, the friction between the elastic body 48 and the moving body 49 causes the moving body 49 to move.
Are driven linearly in the direction of arrow b.

Therefore, by attaching the wiper plate 32 of each of the above embodiments to the moving body 49, the wiper plate 32 can be moved up and down, and the distance between the track surface 11 and the wiper plate 32 can be changed. Further, since the elastic bodies 48, 48 and the moving body 49 are in pressure contact with each other, when the voltage is turned off, the moving body 49 has a self-holding force of stopping at that position by frictional force. Therefore, even when the voltage is OFF, the moving body 49, that is, the wiper plate 32, can maintain the position immediately before the OFF state.

Next, a fifth embodiment of the present invention will be described with reference to FIGS.
An embodiment will be described. FIG. 10 is a plan view of FIG. The tip of the shaft 33 of the linear actuator 31 attached to the side wall 13 is connected to a side plate 53 as a component aligning means arranged on the track surface 11.

The side plate 53 has a rectangular shape, and is arranged upright with its plane portion perpendicular to the track surface 11. A pin 54 fixed to the track surface 11 is attached to the downstream end 53a, and the side plate 53 is slidable in the width direction of the track 11 using the pin 54 as a fulcrum.

The shaft 33 of the linear actuator 31 is connected to the upstream end 53b of the side plate 53.
The linear actuator 31 has been described above with reference to FIG. 4, and the operation is the same. The linear actuator 31 has a base 34 on the outer peripheral surface side of the side wall portion 13.
The shaft 33 penetrates a hole 55 formed in the side wall 13 and is connected to the upstream end 53 b of the side plate 53.

In this embodiment configured as described above, the shaft 33 is slid in the width direction of the track 11 by turning on / off the linear actuator 31, that is, the side plate 53 is slid about the pin 54 as a fulcrum. The track width at the side end 53b is changed. This makes it possible to easily adjust the track width in accordance with the diameter of the part 52 to be transferred and to form a single row.

FIG. 11 shows a component aligning means 76 according to a sixth embodiment of the present invention. The component alignment means 76
The above-described bimorph type piezoelectric element 41 shown in FIG. 8 is arranged on the track surface 11 with its plane portion perpendicular to the track surface 11, and the downstream end 41 a is fixed to the side wall portion 13 by the screw 21. It is fixed to.

Accordingly, when a DC voltage is applied to the bimorph type piezoelectric element 41 as described above, the track 41 is bent and displaced in the width direction of the track 11 with the end 41a as a fixed end. Thus, the track width can be easily adjusted according to the diameter of the component 52.

Next, a seventh embodiment of the present invention will be described with reference to FIGS. FIG.

And the operation is the same. The base 34 of the linear actuator 31 is fixed to an attachment member 58 attached to the inner wall 2a of the bowl 2 with a screw 59.

Next, the operation of the present embodiment will be described. The plate-like part 57 transferred in the lying position
Since the left end portion of the triangular side plate 56 rides on the upper end surface 56a of the triangular side plate 56 from the downstream end portion 56b side with respect to the transfer direction A, the upper end surface 56a is inclined so as to gradually increase with respect to A in the transfer direction. The component 57 is gradually inclined toward the side wall portion 13 and passes through the narrow track width between the upstream end portion 56c of the triangular side plate 56 and the side wall portion 13 in a standing posture.

At this time, in order to correspond to a component having a width W smaller than the component 57, the linear actuator 31 is driven to move the shaft 33 toward the side wall portion 13 so that the downstream end portion 56b The width between the portion 13 is reduced. At this time, the distance between the upstream end 56c and the side wall 13 is slightly reduced. However, if it is not desired to change the width, a hinge mechanism is provided at the upstream end 56c to support the upstream end 56c as a fulcrum. Then, the triangular side plate 56 may be slid in the width direction of the track 11.

Next, an eighth embodiment of the present invention will be described with reference to FIG. A gap 63 a is formed in the center of the track 63, and a thin plate-like rail member 62 is inserted into the gap 63 a with its short direction perpendicular to the track surface 63. At the lower end of the rail member 62, the shaft 33 of the above-described linear actuator 31 is connected to several places (two places in the figure). Therefore, the rail member 62 moves up and down between the gaps 63a by driving the linear actuator 31.

Then, as shown in FIG. 14A, when the upper end of the rail member 62 is slightly protruded from the track surface 63,
By engaging the concave portion 60a of the U-shaped part 60 with the upper end of the protruding rail member 62, the posture of the U-shaped part 60 can be aligned in the same direction and transferred.
A U-shaped component having a different depth of the recess 60a can be accommodated by changing the amount of protrusion of the rail member 62 by driving the linear actuator 31.

As shown in FIG. 14B, for the convex part 61, the rail member 62 is lowered below the track surface 63 so that the convex part 61a of the convex part 61 is engaged with the gap 63a. The components 61 can be transported in the same direction. Of course, it is possible to cope with convex parts having different lengths of the convex part 61a by moving the rail member 62 up and down by driving the linear actuator 31 to change the depth of the gap 63a.

Next, a ninth embodiment of the present invention will be described with reference to FIG. In the present embodiment, a notch 65 is formed in the track surface 11, and a component alignment table 66 is disposed in the notch 65. The downstream end 66a of the component aligning table 66 is attached to the track surface 11 by a hinge mechanism, and the shaft 33 of the linear actuator 31 is coupled to the lower surface of the upstream end 66b.
Therefore, the component alignment table 66 is
By the drive of, it moves up and down with the downstream end 66a as a fulcrum.

Next, the operation of the present embodiment will be described. The cylindrical component 64 transported with its axis parallel to the transport direction A is formed on the upstream end 66b of the component alignment table 66. The head is converted to a standing posture by a drop with respect to the track surface 11. The drop between the component aligning table 66 and the track surface 11 is determined by the axial length of the component 64. Therefore, the linear actuator 31 drives the component aligning table 66 up and down in accordance with the axial length. To adjust the size of the head.

7 is transferred. Here, the diameter of the head 67a is equal to the width W of the gap.
If it is smaller, it cannot be hung. Further, even if the diameter of the shaft portion 67b is larger than the width W of the gap, it cannot be suspended. Therefore, by driving the linear actuator 31, the band plate 68a is slid in the radial direction to adjust the width W of the gap.

Next, referring to FIG. 17, an eleventh embodiment of the present invention will be described.
An embodiment will be described.

When the flat part 69 is transported while the flat part thereof is in contact with the side wall part 13 and reaches the long hole 70, the part 69 from the air outlet 71a It is knocked down by the jet air. Therefore, all the parts 69 that have passed there are transported in this laterally inclined posture. If the height of the component transferred in the standing position along the side wall 13 is lower than the position of the air ejection port 71a,
Since the component cannot be turned sideways, the position of the air ejection port 71a is lowered by driving the linear actuator 31 so that the ejected air hits the component and falls.
