2. Description of the Related Art Conventionally, as a feeding device for a part having a letter-shaped side surface, there is a device disclosed in Japanese Patent Publication No. 1-21045 filed by the present applicant, which has already been put into practical use. ing. FIG. 25 is a perspective view of a part 1 whose side surface is a letter-shaped object to be fed, and the part 1 is composed of an upper plate part 2, a bottom plate part 3, and a support part 4, and a long side 3 a of the bottom plate part 3.
Is longer than the long side 2a of the upper plate portion 2, and the short side 3b of the bottom plate portion 3 has a length substantially equal to the short side 2b of the upper plate portion 2. This posture is a predetermined feeding posture, and the direction indicated by arrow p is the predetermined feeding direction.

The component 1 is moved by the torsional vibration parts feeder 20 shown in a plan view in FIG. 26 to be adjusted in the posture by moving the track 38. However, after the second feeding unit 41, the component 1 has the bottom plate portion 3 on the long side. 3a is aligned in the radial direction of the bowl 21, that is, the short side 3b is in contact with the peripheral wall and is transferred. As shown in FIG. 27 showing a cross section taken along line [27]-[27] in FIG. 26, a space 52 is provided by the third transfer path 50 and the fourth transfer path 51 of the second feeding section 41.
The long side 3a of the bottom plate portion 3 of the component 1 is suspended across the gap 52, but the short side 3b cannot be crossed and falls downward so that the transfer direction of the component 1 is selected. . Also,
As shown in FIG. 28, which shows a cross section taken along line [28]-[28] in FIG. 26, the component 1 has the upper plate portion 2 in the groove 55 formed by the side wall portions 53 and 54 in the posture holding path 42. The short side 3b of the bottom plate portion 3 is transferred in the transfer direction. Then, it is turned upside down through the reversing chute 22 in FIG.

There is a limit to the transfer speed because it is a method in which a is transferred in the radial direction. That is, in the transfer by the torsional vibration, when the transfer part is operated so as to increase the transfer speed, the part to be transferred is oriented so that its long side is in contact with the peripheral wall of the transfer path. Since 3b is transferred by contacting with the peripheral wall of the transfer path, the feeding capacity is limited to about 150 pieces per minute at the maximum. Further, when there is only a slight difference in size between the upper plate portion 2 and the bottom plate portion 3, the achievement rate of the predetermined feeding posture is low, and its improvement has been desired.

Since the posture check by the second optical sensor 155 is the same as that by the third optical sensor 156, its explanation is omitted.

The second optical sensor 155 and the third optical sensor 156
Although the component F blown away and eliminated by the posture inspection by the device falls into the second pocket 191, FIG. 19 and FIG.
Referring to, the second pocket 191 has an opening 1 on its bottom surface.
A tunnel 193 having 92 and a tunnel 195 having an opening 194 are provided so that the component F dropped into the pocket 191 is returned to the bottom surface 82 of the bowl 81.

The posture holding unit 19 is provided downstream of the posture inspection unit 170.
0, and [22]-[2 in FIG. 19 and FIG.
2] Referring to FIG. 22 showing a cross section in the direction of the line, the bowl 81
A guide plate 197 and a restraining plate 198 are attached to a track block 199 fixed to the peripheral edge of the device, and have a width and height in which the component F in the posture and the transport direction shown in FIG.
As a track 196 having a horizontal transfer surface, it is provided to transfer the part F to the linear vibration parts feeder 200 connected downstream.

The linear vibrating parts feeder 200 is connected to the downstream end of the torsional vibrating parts feeder 100 with a slight gap, the whole of which is shown in FIGS. Referring to FIG. 3, the linear vibrating parts feeder 200 includes a vibrating trough 211 that transfers the part F and a driving unit 201 thereof.

In the drive unit 201, a movable core 202C is hung from a movable block 202 which is integral with the bottom plate of the vibration trough 211, and both ends of the movable block 202 in the transfer direction are fixed blocks 204 on a mount 208 by a pair of inclined leaf springs 203. Is connected with. An electromagnet 206 having a coil 205 wound around the fixed block 204 has a movable core 202C.
The drive unit 201 is formed so as to face each other with a slight gap therebetween, and the entire drive unit 201 is covered with a soundproof cover 207. The vibration trough 211 and the pedestal 208 that supports the drive unit 201 are fixed on the common base plate 69 via a vibration-proof rubber 209. Then, when an alternating current is applied to the coil 205 of the drive unit 201, linear vibration in the direction indicated by the arrow n is applied to the vibration trough 211, and the component F is shown in FIG.
In FIG. 4, it is transferred from right to left.

The vibration trough 211 corresponds to [2 in FIG.
3]-[23] A partial cross-section in the direction of the line is referred to, and the vibrating trough 211, its rising wall 211a, and the upper lid 212 form an angular tunnel shape in the posture F shown in FIG. Width and height transfer path 21 for transferring
It is said to be 3 . The transfer path 213 can also transfer the component F in an upside down posture while keeping the transfer direction shown in FIG. Therefore, as shown in FIG. 23, the vibration trough 21
The light emitting element 216a and the light receiving element 216b of the fourth optical sensor 216 are arranged on both sides of 1 to perform a final attitude check. That is, on the transfer surface of the vibration trough 211, the four horizontal light small holes 214 provided on the rising wall 211a at the height position of the top plate 5 when the component F is in the posture and transfer direction shown in FIG. 1A. (Not shown as four) and the through hole 215 formed by cutting out the vibration trough 211 and the upper lid 212, the light emitting element 216 is formed.
It serves as a passage of light from a to the light receiving element 216b.

That is, the attitude check is performed by the fourth optical sensor 216 in the same manner as the first optical sensor 154 of the front / back correction unit 140, and the part F in the attitude and transfer direction shown in FIG. Since the part 5 does not block the light of the fourth optical sensor 216 and thus allows the light to pass through as it is, when the parts F in which the top plate part 5 and the bottom plate part 6 are turned upside down are mixed with each other while keeping the transfer direction, this is caused. Since the bottom plate portion 6 blocks the light from the fourth optical sensor 216, the entire system of the torsional vibration part feeder 100 and the linear vibration part feeder 200 is stopped when the signal is received.

Further, at the tip of the vibrating trough 211, a cross section taken along line [24]-[24] in FIG. 3 is shown.
4, a compressed air pipe 217 is inserted and screwed into a mounting member 218 on the upper surface of the upper lid 212, and an air ejection hole 219 is formed through the upper lid 212 in a downwardly inclined direction from the tip end thereof in the transfer direction. Has been. This air ejection hole 2
Air is constantly ejected from 19, and the component F transferred through the transfer path 213 is pressed from above by the ejected air to eliminate the vibration of the component F and send it to the next process.

It should be noted that the fifth optical sensor 2 having an optical path vertically penetrating the transfer path 213 is provided on the upstream side of the vibration trough 211.
The light emitting element 221a and the light receiving element 221b of No. 21 are parts F
Is provided to detect the overflow of the. That is, when the light of the fifth optical sensor 221 is interrupted by the transferred component F, the transfer is determined to be normal and the state is continued, but the light of the fifth optical sensor 221 continues for a predetermined time or more. If it is shut off, it is determined that an overflow due to clogging or the like has occurred, and the torsional vibration part feeder 1 along with the linear vibration part feeder 200 is determined.
00 is also stopped.

The component feeding apparatus according to the embodiment of the present invention is constructed as described above, and its operation will be described below.

It is assumed that the apparatus of this embodiment shown in FIGS. 3 and 4, that is, the torsional vibration part feeder 100, the linear vibration part feeder 200, and their associated equipment are energized and are all in an operating state. . The deficiency of the part F in the bowl 81 of the torsional vibration part feeder 100 is performed by the empty detection sensor 84 determining whether or not the part F is transferred in the groove 83. When the deficiency is detected, the hopper 61 detects the deficiency. A fixed amount of the component F is cut out and supplied onto the bottom surface 82 of the bowl 81 via the chute 62. Therefore, a large number of parts F are formed on the bottom surface 82 of the bowl 81.
Are to be housed (shown scattered in FIG. 4). At this time, about the values, 30% of the parts F in the posture shown in FIG. 1A and 5% in the parts B of FIG.
0%, and A and B in FIG. 2 are present in a proportion of 20% in both cases.

In FIG. 4, the component F receives torsional vibrations, moves to the peripheral portion on the bottom surface 82, rides on the truck 85, contacts the peripheral wall portion 89, and ascends while being transferred in the direction of arrow b. At this time, when the part F is excessively transferred on the truck 85, some of the cutout 87 is removed from the bowl 8
The transfer amount is adjusted by returning to the bottom surface 82 of 1.

The component F is transferred to the monolayering unit 90 and reaches the separation plate 91 first, but when there is a component F transferred on top of the component F in the posture A or B in FIG. 5, the lower part F is transferred along the end face of the separating plate 91, and the upper part F is transferred in contact with the peripheral wall portion 89, so that overlapping separation is performed. The other component F does not overlap the component F in the posture of A or B in FIG.

The rapid delivery gate plate 104 downstream of the separation plate 91.
In FIG. 7, with reference to FIG. 7, fragments F ′ and the like accompanying the component F are discharged from the gap 108 provided between the lower end of the quick-discharging gate plate 104 and the transfer surface of the truck 85.
In addition, this quick-release gate plate 104 is urgently used in the bowl 81.
When it is desired to take out the component F from the above, the component F is lifted upward and opened to a large extent to serve as a take-out port.

In the wiper 93 provided downstream of the rapid delivery gate plate 104, the component F is made into a single layer again. That is, referring to FIG. 5, the component F that is transferred onto the component F in the posture A or B in FIG.
If there is, the lower part F is transferred under the wiper 93, while the upper part F and the side-standing part F shown in A or B of FIG. Then, it is guided by the wiper 93 and returned to the track 85 on the inner side of one circumference.

Most of the parts F that have passed through the wiper 93 have the postures shown by A or B in FIG. 1 and reach the first sorting section 110 without being fixed in the transfer direction.
Referring to, these parts F pass under the posture selection plate 111, and further under the posture selection plate 111, and on the track 85, the peripheral wall portion 89.
Will be transferred to.

A single layer is formed by the wiper 93,
Alternatively, the component F in the standing posture shown by B cannot enter below the posture selection plate 111 and is transferred in contact with the posture selection plate 111. Therefore, here, the component F in the posture A or B in FIG. Screening is performed with the component F having the posture of A or B in FIG.

The part F having the attitude of A or B in FIG. 2 is transferred to the inside of the recess 116 while being mostly transferred to the recess 116 provided on the track 85 while being transferred to the attitude selection plate 111. Will be done. The component F that has fallen and has the posture of A or B in FIG. 1 moves up from the recess 116 to the track 85, then moves in the direction of the arrow d along the slope, passes under the posture selection plate 111, and passes through the peripheral wall. Reach part 89. On the other hand, even if the component F having the posture of A or B in FIG.
11 is transferred to the first pocket 117 provided on the track 85 and falls down as indicated by an arrow e. Further, the first pocket 117 is transferred to the inside of the first pocket 117 and is moved inward by one circumference as indicated by an arrow f. It is returned to the truck 85.

As described above, the part F that has passed through the first posture selecting section 110 reaches the second posture selecting section 120 while the transfer direction is indefinite in the posture of A or B of FIG. Referring to FIG. 9, FIG. 10, and FIG. 11, the component F has a second posture sorting section 1 having a common transport surface with the track 85 of the first sorting section 110.
20 is transferred to the upper surface 121 of 20 and immediately slips off the slope 123, either directly or via the slope 122 into the first V-groove track 128. At this time, the component F is in a posture in which the top plate portion 5 or the bottom plate portion 6 is in contact with the slope 123, and the long side 6a of the bottom plate portion 6 is either laid down in the transfer direction or is erected.

As shown in FIG. 10 and FIG. 12, the slope 123 is the slope 1 at the portion where the first guide plate 126 is not provided.
The component F, which has a height reduced by 22 and stands on the long side 6 a, has the first air ejection hole 13 at the upper end of the bottom plate 6.
Since the air constantly ejected from 2 hits, it is blown off to the upper surface 88 of the peripheral portion of the bowl 81 as shown by the alternate long and short dash line and the arrow h, and is eliminated. Therefore, the part F that has passed through this sorting and is further transferred through the first V-groove track 128 has the top plate portion 5 or the bottom plate portion 6 in contact with the inclined surface 123 and the long side 6a directed in the transfer direction.

At the downstream of the first air ejection hole 132, the component F is transported while the posture change is suppressed by the second guide plate 136. Further, referring to FIG. 9, the second guide plate 136 is missing. By the second air ejection hole 134 provided at the position, the component F with the long side 6a standing up, that is, the component F having the short side 6b as the transfer direction is blown off like the first air ejection hole 132. , The selection is confirmed. Also here, the blown-out part F
Falls on the upper surface 88 of the peripheral edge of the bowl 81 through the slope 138, but is transferred to the truck 85 and then returned to the truck 85.

The part F which has passed through the second posture selection section 120 is transferred to the front / back correction section 140, and the first part shown in FIGS.
Of the parts F that reach the position just below the optical sensor 154, but have the long side 6a as the transfer direction, as shown in FIG. 15, the one in which the bottom plate portion 6 is in contact with the slope 143 has four top plate portions 5. The light small holes 148 ₁ , 148 ₂ , 148 ₃ and 148 ₄ cannot be temporarily shielded, and the light from the light emitting element 154 a of the first optical sensor 154 to the light receiving element 154 b is not blocked so that they are transferred as they are. On the other hand, as shown in FIG. 16, the one in which the top plate 5 is in contact with the slope 143 is the bottom plate 6
Light blocks the light small holes 148 ₁ , 148 ₂ , 148 ₃ , 148 ₄ at a time, the light of the first optical sensor 154 is blocked, and air is instantaneously emitted from the third air ejection hole 152 in response to the signal. When jetted, the component F is inverted as shown by the alternate long and short dash line, that is, as shown by the arrow j, and the bottom plate 6 is moved to the slope 1
The posture is such that it contacts with 44. Therefore, the first optical sensor 15
4 and the component F that has passed through the obverse / reverse correction mechanism by the air ejection holes 152, with the long side 6a as the transfer direction, with the bottom plate portion 6 in contact with either the slope 143 or the slope 144 of the second V-groove track 142, that is, In the posture and transfer direction shown in FIG. 1A, the sloping surface 143 or the sloping surface 144 comes into contact with the sloping surface 143 or the sloping surface 144 and the transfer is performed in two rows. It should be noted that the jetted air is inverted or tilted to the inclined surface or the inclined surface 144. At this time, the part F may not rotate more than 90 degrees depending on the portion receiving the jetted air or the strength of the jetted air. This is prevented by the step portion or the inclined surface 145 between the inclined surfaces 144 and 145 as shown in the figure, and surely pivots as shown by the alternate long and short dash line j so that the other inclined surface 144 is placed in an upright posture. Transferred to the downstream side. Since the inclined surface 145 is inclined toward the inclined surface 144, even if the inclined surface 145 is vigorously tilted to reach this surface, the inclined surface 145 is guided to the other inclined surface 144 as it is while maintaining its upright posture.

After passing through the front and back straightening section 140, the merging section 1
The parts F, which are on the slope 163 or the slope 164 of the third V-groove track 162 in 60 and are transferred in two rows, are merged in the U-groove track 165 and have the posture and transfer direction shown in A of FIG. Become a line. Note that FIG.
The target line V ₂ of the third V-groove track 162 is coaxial with the vertical line V ₁ which intersects the point P, as shown by, and in the second V-groove track 140 on the upstream side, the target line V ₂ is the vertical line as shown in FIG. Although tilted to the left side with respect to V ₁ to ensure the tilting action to the upright posture by the ejected air, the target line V ₂ coincides with the vertical line V ₁ passing through the point P in the third V groove track 162. This and also by aligning the centerline of the U-groove track 165 connecting to it as shown in FIG.
The component F having an upright posture on the slopes 163 and 164 can surely join the U-groove track 165 in the upright posture.

After being lined up at the merging section 160, the parts F are transferred to the posture inspection section 170. That is, here, in the component F having the posture and the transfer direction shown in FIG. 1A, the one in which the top plate portion 5 is on the lower side and the bottom plate portion 6 is on the other side in the same transfer direction is inspected and mixed. If it does, its exclusion will take place. Referring to FIG. 19, after confirming the final monolayering in the separation unit 171, the second optical sensor 155 for posture inspection is performed.
And the third optical sensor 156 are arranged in series and a double inspection is performed. Second optical sensor 155 and third optical sensor 15

With four light holes 177 ₁ , 177 ₂ , 177 ₃ , 177
₄ the light emitting element 156 of the optical sensor 156 does not temporarily shielding the
The light from a to the light receiving element 156b is not blocked so that it is transferred as it is, but if upside down ones are mixed, the bottom plate portion 6 has four light small holes 177 ₁ , 177 ₂ ,
Since 177 ₃ and 177 ₄ are temporarily blocked and the light of the optical sensor 156 is blocked, air is momentarily ejected from the air ejection hole 188 and the part F is blown to the second pocket 191 as indicated by an arrow m. And eliminated. That is, the posture inspection at this time is the same method as the posture check in the front / back correction unit 140 described above. The action of the third optical sensor 156 and the air ejection hole 188 is the same as that of the second optical sensor 15 on the upstream side.
5 and the air ejection holes 184 are similar.

The component F dropped into the pocket 191 is a tunnel 193 having an opening 192 in the pocket 191.
Alternatively, it is returned to the bottom surface 82 of the bowl 81 via a tunnel 195 which also has an opening 194.

The component F that has passed through the posture inspection unit 170 has a width and a height in the posture holding unit 190 in which the component F in the posture and the transport direction shown in FIG.
Further, it is transferred to the downstream end of the torsional vibration parts feeder 100 on the track 196 having a horizontal bottom surface so that the pressing plate 198 does not change the posture.

In the linear vibration parts feeder 200 following the torsional vibration parts feeder 100, referring to FIG. 23, the vibration trough 211, its rising portion 211a, and the upper lid 212 are used to move the part F in the posture and transfer direction shown in FIG. Is used as a transfer path 213 to be transferred to the next process and supplied. During this time, the fourth optical sensor 216 shown in FIG. 23 performs a final check on the presence or absence of the component F, which is upside down from the posture F of FIG. 1 and the component F in the transfer direction, and if a mixture is found. If so, both the linear vibration parts feeder 200 and the torsional vibration parts feeder 100 are stopped. The posture check by the fourth optical sensor 216 is performed by the four optical small holes 214 ₁ , 214 ₂ , 214 ₃ , 214 _4.
Is determined by whether or not the light from the light emitting element 216a whose light path is to the light receiving element 216b is blocked by the bottom plate portion 6 of the component F, and is the same as the above-described check in the front / back correction portion 140.

Further, the component F is pressed by the air constantly ejected from the air ejection hole 219 which is provided in the upper lid 212 at the tip end portion of the vibration trough 211 and faces downward in the transfer direction. It is supplied to the next process while eliminating the linear vibration.

Further, in the upstream portion of the linear vibrating parts feeder 200, there is an optical path which vertically penetrates the transfer path 213 of the vibrating trough 211, and the fifth part for monitoring the overflow is provided.
The optical sensor 221 also stops both the linear vibration part feeder 200 and the torsional vibration part feeder 100 when the overflow of the part F due to clogging or the like is detected.

The embodiments of the present invention have been described above. Of course, the present invention is not limited to these, and various modifications can be made based on the technical idea of the present invention.

For example, in the present embodiment, the torsional vibration part feeder 100 adjusts the posture and transfer direction of the component F, and the linear vibrational part feeder 200 holds them and supplies them to the next process. Feeder 10
The linear vibrating parts feeder 200 may be omitted by connecting a linear chute downstream of 0 to supply the vibration to the next step by the vibration of the driving unit 71 of the torsional vibration.

Further, in this embodiment, the posture selection plate 11
The component F having the posture shown in A or B of FIG. 2 can be selected by 1 and the component F overlapping on the component F having the posture shown in A or B of FIG. Either or both of 93 may be omitted.

Further, in this embodiment, the first to fourth optical sensors 154 and 1 for checking the posture of the component F are used.
55, 156, 216, which is the optical path of the first optical sensor 154 as a representative example thereof.
Although the light small holes 148 ₁ , 148 ₂ , 148 ₃ and 148 ₄ of the book have the same diameter, the diameter may be different depending on the shape of the parts to be transferred, or a plurality of holes other than four may be used. Furthermore, four light small holes 148 ₁ , 148 ₂ , 148 ₃ , 14
Instead of 8 _4, it is also possible to slit the same length as the length of the column of light stoma.

Further, in the present embodiment, the part F having an extremely small shape is targeted for feeding, but it is also possible to feed parts larger than this with the same device.

Further, in the above-mentioned embodiments, the parts whose side faces have the letter-like shape have been described. However, the shape is not limited to this, and like the part F, a stable standing posture is taken due to the relationship of the center of gravity and the shape. Of these, the present invention can be applied to any part as long as it is a part that can stably take an upright posture and an inverted posture.

In the above embodiment, the U-groove track 165 serving as a confluent track is guided by the second V-groove track 162 through the second V-groove track 142 so as to have an upright posture. However, in some cases, the third V-groove track 162 may be omitted and the second V-groove track 142 may be directly introduced into the U-groove track 165. Of course, the valley bottom line of the second V-groove track 142 is aligned with the center line of the U-groove track 165.

Instead of the U-groove track 165, a track having a horizontal transfer surface may be used. In this case, the cross section of the track may be trapezoidal or U-shaped, and may be slightly inclined inward or outward of the bowl by several degrees. In any case, the center line that is aligned with the valley bottom of the second V-groove track 142 on the upstream side and determines the transfer direction is defined, and the transfer surface of the component F is horizontal or radially inward or in the upright posture. It may be introduced into a track inclined several degrees outward. In some cases, instead of the U-groove track 165, a V-groove may be used as a confluence track in which the angle formed by the V is almost 180 degrees.

In the above embodiment, the second V-groove track 142, the third V-groove track 162 and the U-groove track 165 are used.
Although they were formed in an arc shape so as to form a part of the bowl, they may of course be formed in a straight line, and instead of a vibrating parts feeder forming a spiral track, a linear trough is used. The present invention is also applicable to a linear vibrating feeder equipped with.

[0077]

As described above, according to the apparatus for feeding parts of the present invention, only the upright posture of the three-dimensional parts can be efficiently supplied to the next process. Further, specifically, in the bowl of the torsional vibration part feeder, the long side of the bottom plate portion of the component is brought into contact with the peripheral wall to be transferred.
Even though the object to be sent is an extremely small part, the transfer capacity is about 4 times that of the conventional example in which the long side is moved in the radial direction, and about 500 pieces are sent per minute. You can Furthermore, in addition to the reliable selection action in the first posture selection unit and the second posture selection unit, the posture inspection unit is provided with the second optical sensor and the third optical sensor in series, and double inspection is performed to determine those other than predetermined ones. Since they are excluded, the achievement rate of the predetermined feeding posture is 99.98%, which is an extremely high value. In addition, the linear vibration parts feeder is connected to stop the whole system when the fourth optical sensor detects a position other than the predetermined feeding posture, so that the next feeding process is performed by the predetermined feeding. Nothing other than posture is supplied.
