Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a component feeding device, and more particularly, to a device for transporting components by adjusting the orientation of the components, such as upside down or front and back, and the direction of transfer.
[0002]
[Prior art]
In the parts feeding device, for example, the selection of the front and back of the parts and the selection of the direction of transfer are performed by dedicated sorting mechanisms arranged in series on a track of a vibrating parts feeder for transferring the parts, and a predetermined posture and a predetermined transfer are performed. The components that are not in the same direction are blown away by the blowing air to eliminate them, and only the components in a predetermined posture and in a transfer direction are discharged from the downstream end.
[0003]
[Problems to be solved by the invention]
However, in recent years, electronic components of a very small size are often targeted for reconciliation, and the vibrating parts feeder is also reduced in size to, for example, about 200 mm in diameter. The degree of freedom is reduced. In other words, for the purpose of high-precision sorting, it is preferable to arrange the same sorting mechanism in series and double-check to eliminate those that do not have a predetermined posture and transfer direction. Since a rowing mechanism is also required, it is difficult to arrange the sorting mechanism on the track with a sufficient margin. In addition, since the piping of the jet air accompanying each sorting mechanism also takes up space, the degree of freedom in terms of space for providing other necessary auxiliary equipment such as a component replenishing device is reduced.
[0004]
Accordingly, it is an object of the present invention to provide a component arranging device in which a sorting mechanism can be arranged with a sufficient margin, and as a result, a component arranging device having a large degree of freedom in terms of space even when ancillary facilities are installed.
[0005]
[Means for Solving the Problems]
The present invention combines a reflection type optical fiber sensor and a transmission type optical sensor.At the same point, the orientation of the parts and the direction of transfer in selecting the partsCheck if any of these are not as specifiedSort outLike that. Therefore, although the configuration of the selection mechanism is slightly complicated, the number of the selection mechanisms is reduced, so that the degree of freedom in space is high.BecomeIn addition, a double-check can be performed sufficiently, and a parts sorting device with high sorting accuracy can be obtained.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described with reference to the drawings.
[0007]
FIG. 11 shows a component selection unit 171;In the same placeThe transmission type optical sensor 161 'and the reflection type optical fiber sensor 181 are used to select the orientation of the component A and the direction of transfer. The part A is transported in contact with a side plate 155 'attached to the track block 153' by a sorting truck 154 'inclined slightly downward toward the outside of the diameter of the bowl 121 formed on the track block 153' on the mounting block 152 '. Is done. The light emitting element 161A 'and the light receiving element 161B' of the transmission type optical sensor 161 'are provided with a space 159', a notch 157 'of the side plate 155', and a hole 164 'of the protector 163' as an optical path. Is in a predetermined posture, and when the main body 1 is lifted from the sorting track 154 ′, the irradiation light is not cut off and is allowed to pass as it is.IsBy blocking the irradiation light, air from the compressed air pipe 169 'is blown out from the air blowout hole 156' provided in the side plate 155 ', and the part A is blown off and removed.
[0008]
Further, a reflection type optical fiber sensor 181 having a lens barrel 182 having a built-in lens at its tip is fixed to a support column 172 on a support bar 162, and the optical axis P of the irradiation light is predetermined on a sorting track 154 '. The component A in the direction of transfer is removed and directed to the inclined surface 158 ′, so that only when the component A in the horizontal direction is transferred, reflected light of high intensity is received. When the reflection intensity is high, air is similarly blown out from the air blowout hole 156 'to blow out and remove the part A in the horizontal direction.
[0009]
FIG. 24 shows another sorting unit 271.IndicatesThe reflection type optical fiber sensor 281 and the reflection type optical fiber sensor 291In the same placeThe posture of the component D and the direction of transfer are sorted out. The part D is transported in contact with the side wall 275 through the sorting track 274 inclined downward toward the outside of the bowl 221, and the tip of the reflection type optical fiber sensor 281 fixed to the support member 279 is moved to the side wall 275 of the track block 272. The front and rear of the component D are detected by detecting the lead 9 of the component D. That is, when the lead 9 is detected with the component D facing backward, the air from the compressed air pipe 289 attached to the suppression block 273 is ejected from the air ejection hole 286 to blow off and remove the component D.
[0010]
Further, a reflection type optical fiber sensor 291 having a lens barrel 292 having a built-in lens at the tip is fixed to a mounting member 296 on a supporting member 295, and the optical axis Q of the irradiation light is set to a predetermined value on a sorting track 274. The component D in the transfer direction is set so as to be removed, and only when the component D in the horizontal direction is transferred, reflected light with a small intensity is received. When the reflection intensity is low, air is similarly blown out from the air blowout hole 286 to blow out and remove the part D in the horizontal direction.
[0011]
In sorting in this wayA part having a different posture and a different transfer direction, for example, a vertically long part, having a normal posture and the same transfer direction at the time of transfer, the main body of which is floated from the sorting truck by a foot and transferred in the longitudinal direction. Or if,In the case of transporting in the longitudinal direction while maintaining the asymmetry of the lead provided asymmetrically on both sides as it is,Check the posture and transfer direction of these parts at the same location,Either isIf it is not as specified, the air is ejected from the air ejection holes to eliminate and select the parts.Therefore, the sorting mechanism is different from the conventional case where a sorting mechanism is provided for each component posture and transfer direction. Therefore, the same sorting mechanism is installed in series, double checking can be sufficiently performed, and a parts sorting apparatus with high sorting accuracy can be obtained. In addition to the sorting mechanism, auxiliary devices such as a single-layer / single-rowing mechanism and a transfer amount adjusting mechanism that need to be installed can also be installed with a sufficient margin, so that the sorting accuracy is improved from that aspect as well.

That is, when the component A is in a posture in which the main body 1 is raised with the bottom surface G on the lower side, the light from the light emitting element 161A of the transmissive optical sensor 161 to the light receiving element 161B is not blocked, but the other posture. In this case, by blocking the light, the vertical position of the component A is detected.
[0029]
Further, a joint 168 of a compressed air pipe 169 is inserted and screwed into the zigzag-shaped through hole 167 formed in the track block 153 from the outer peripheral side, and an opening on the inner peripheral side of the through hole 167 is formed by the air jet of the side plate 155. It is connected to the hole 156. Then, when the light from the optical sensor 161 is shut off, a solenoid valve (not shown) of the compressed air pipe 169 is instantaneously opened, and air is ejected from the air ejection hole 156 of the side plate 155, so that the light-shielded component A is removed. They are blown away and eliminated.
[0030]
Returning to FIG. 6, between the first sorting unit 151 and the second sorting unit 171, the base of the wiper 174 is attached with a bolt 174 b to a mounting block 173 fixed to the peripheral wall 123 with a bolt 173 b, and The subject is provided obliquely above the sorting truck 154.

Referring to FIG. 11 which is a cross-sectional view taken along the line [11]-[11] in FIG. 6, the second sorting unit 171 is a transmission type optical sensor 161 similar to the first sorting unit 151 shown in FIG. There is a mechanism for selecting the posture of the component A based on whether or not light is blocked between the light emitting element 161A 'and the light receiving element 161B'. Therefore, members corresponding to the members of the first sorting unit 151 including the optical sensor 161 'are denoted by the same reference numerals with ('), and the description of this portion is omitted.
[0032]
Further, in addition to the above-mentioned transmission type optical sensor 161 ', a lens is built in a notch of an inverted L-shaped support pillar 172 which is set up at an intermediate portion of an L-shaped support bar 162' and fixed with a bolt 172b. The threaded portion 183 of the reflection type optical fiber sensor 181 having the lens barrel 182 at the tip is sandwiched, and is fixed with bolts 181b while holding down the outside with a holding plate (not shown). In the reflection type optical fiber sensor 181, the light emitting elementFromThe reflected light of the light applied to the detection target via the optical fiber returns to the light receiving element via the optical fiber again, and the sensor detects the state of the detection target based on the magnitude of the reflection intensity at that time. The optical axis P of the irradiation light of the optical fiber sensor 181 is set on the sorting track 154 by removing the component A in a predetermined transfer direction, so that the reflected light with high intensity returns only when the component A is in the horizontal direction. Has become. Then, when the component A in the horizontal direction is detected, the solenoid valve (not shown) of the compressed air pipe 169 'is instantaneously opened, and the compressed air introduced from the joint 168' is supplied from the air ejection hole 156 'of the side plate 155'. Air is blown out to blow out and remove the sideways component A. In other words, the air ejection hole 156 'is shared by both the transmission type optical sensor 161' and the reflection type optical fiber sensor 181, and the second sorting unit 171 checks the posture of the component A and the direction of transfer at the same time. Air is blown if any of them is not as prescribed. Therefore, the equipment cost of the compressed air piping is reduced.
[0033]
A discharge unit 191 is provided downstream of the second sorting unit 171. Referring to FIG. 14 which is a cross-sectional view taken along the line [14]-[14] in FIG. 6, and FIG. 15 which is a cross-sectional view taken along the line [15]-[15], the peripheral portion of the bowl 121 is notched. A track block 192 is provided, and a flat transfer surface and a side wall 195 of the discharge track 194 are formed at a position where the track block 192 is connected to the upstream sorting track 154, and are fixed with bolts 192b as shown in FIG. Have been. A guide plate 193 is attached to the inner surface of the track block 192 by screws 193b, and a holding plate 196 is fixed to the surface of the side wall 195 by screws 196b with a "knob". Are formed, and the parts A having a predetermined posture and a transfer direction are transferred only in a single row and a single layer. FIG. 14 shows track blocks 152 and 153 on the upstream side together with bolts 152b and 153b for fixing them. Note that a linear vibration parts feeder for supplying the parts A to the next process is connected to the parts feeding apparatus 100, but the description thereof will be omitted.
[0034]
The component feeding device 100 according to the first embodiment is configured as described above. Next, the operation thereof will be described.
[0035]
In the parts feeding device 100 shown in FIGS. 5 and 6, a large number of parts A are accommodated in the bottom surface 122 of the bowl 121, an alternating current is supplied to the coil 114, and the coil 121 is turned counterclockwise when viewed from above. It is assumed that torsional vibration is applied and various optical sensors in the first sorting unit 151 and the second sorting unit 171 and other compressed air sources are also operating.
[0036]
Referring to FIG. 6, component A in a random position on bottom surface 122 of bowl 121 receives a transfer force in the direction of arrow m while being moved to the periphery by the centrifugal force of torsional vibration, and flat track 124 from starting point 124s. Is transferred in contact with the side wall 125 while the posture and the direction of the transfer are undefined.
[0037]
The part A is transported along the flat track 124 to reach the rapid exit gate 131. Referring to FIG. 7 as well, in a normal state, the component A is transported in contact with the inner peripheral surface of the rapid exit gate 131 which is almost aligned with the side wall 125 and is transported as it is. pass. Since the track width is narrowed by the notch 135 provided in the flat track 124 at a position almost opposite to the rapid-moving gate 131, of the parts A which are conveyed excessively in multiple rows The component A on the inner peripheral side falls into the notch 135 and the transfer amount of the component A is adjusted. The component A that has fallen into the notch 135 is transported in the notch 135 and falls from the downstream end to the bottom surface 122 and returns.
[0038]
The part A that has passed the outer peripheral side of the notch 135 moves to the J-groove track 141 via a small step from the downstream end of the flat track 124 with reference to FIG. During this time, the component A that overflows when shifting from the flat track 124 to the upstream J-groove track 141 falls into the notch 136 and is returned to the bottom surface 122 as in the notch 135. During the transfer of the component A in the round groove portion of the J-groove track 141, the component A takes a direction in which the position of the center of gravity becomes lower, that is, a predetermined transfer direction, so that the ratio of the component A in the predetermined transfer direction increases. I do. Further, at the connection point between the J-groove track 141 and the J-groove track 142 where the transfer direction changes, and also in the subsequent J-groove track 142, the remaining part A which is not in the predetermined transfer direction takes the predetermined transfer direction. . Therefore, at the downstream end of the J-groove track 142, the component A is almost always in a predetermined transfer direction while the orientation of the component A is not fixed.
[0039]
Next, referring to FIG. 9, the part A is transferred to the round groove track 143 and transferred while maintaining the transfer direction. Then, the flat part track 144 to be described later is cut out via the transition portion 143t shown in FIG. The process proceeds to the first sorting unit 151 formed in the inserted track block 153.
[0040]
As shown in FIG. 10, the component A in the first sorting unit 151 is transported on the sorting track 154 in contact with the side plate 155 to block light from the light emitting element 161A of the transmission type optical sensor 161 to the light receiving element 161B. In response to the selection of the posture based on the presence / absence, the component A which is not in the predetermined posture is blown off by the jet air from the air ejection hole 156 of the side plate 155 and is eliminated, and only the component A having the predetermined posture is transferred to the downstream side. Since the sorting of the posture in the first sorting unit 151 is similar to the sorting of the posture in the second sorting unit 171, the details of the sorting will be described in the second sorting unit 171.
[0041]
If there is a component A that has passed through the first sorting unit 151 and has been stacked by passing through the subsequent wiper 174, only the lowermost component A is transferred to the second sorting unit 171 on the downstream side, and the second layer A The component A described above is guided to the inner peripheral side along the wiper 174 and falls into the bowl 221.
[0042]
The component A that has passed through the wiper 174 is subjected to the sorting of the posture and the sorting of the transfer direction in the second sorting unit 171 shown in FIG.receive. As in the first sorting unit 151, the part A is transported on the sorting truck 154 'in contact with the side plate 155'. The details of the attitude sorting are shown in FIG. 11 along the line [12]-[12]. This is shown in FIG. 12, which is a cutaway view. 12A and 12B are views of the same portion, but a track block 147 having a flat track 144, a side wall 145, and a downwardly inclined surface 148 formed from the flat track 144 toward the inside of the bowl 121 in a radial direction. A sorting track 154 'and an inclined surface 158' similar to the inclined surface 148 on the upstream side are formed in the attached track block 153 'with the notch inserted therein, and a side plate 155' whose surface is aligned with the side wall 145 on the upstream side. Are attached to the track block 153 'with screws 155b'. In the side plate 155 ', an air ejection hole 156' is opened following the through hole 167 'for compressed air, and a cutout 157' is formed as an optical path of the optical sensor 161 '. Installed above is a lens barrel of the optical fiber sensor 181 for selecting the direction of transfer.
[0043]
In FIG. 12, the component A is transferred from the right to the left, but as shown in FIG. 12A, the component A is in a predetermined posture, and the main body 1 is moved from the sorting track 154 'by the thickness of the electrode 2. When the optical sensor 161 is floating, the notch 157 as an optical path of the optical sensor 161 is not completely blocked at one time, so that no air is ejected from the air ejection hole 156 and the component A passes through as it is. On the other hand, as shown in FIG. 12B, when the component A is transported in contact with the sorting truck 154 with the bottom surface G facing upward and the top surface E facing downward, the notch 157 in the optical path is blocked. Therefore, air is ejected from the air ejection holes 156, and the component A is blown off and eliminated as shown by the dashed line. FIG. 12B shows an example in which the component A has the top surface E on the lower side, but the same applies to a case where any one of the both side surfaces F is on the lower side.
[0044]
The details of the selection of the transfer direction are shown in FIG. 13 which is a partially broken plan view along the line [13]-[13] in FIG. FIG. 13 is a view of the same place as that of FIG. 12 from a different angle, and FIGS. 13A and 13B are views of the same place. As described above, the track block 147 having the flat track 144 is cut. A sorting track 154 'is formed in the track block 153' which is fixed and chipped, and a side plate 155 'is attached to the track block 153'. The side plate 155 'has an air ejection hole 156 following a through hole 167' for compressed air. 'Is open. The irradiation point R of the optical fiber sensor 181 is set on the inclined surface 158 'on the inner peripheral side of the sorting track 154', as indicated by a dashed line. In addition, a light emitting element 161A 'of the reflection type optical sensor 161' and a light receiving element 161B 'indicated by a two-dot chain line are present in the vicinity.

In FIG. 13, the component A is transferred from the right to the left. However, as illustrated in FIG. 13A, when the component A is transferred with the end surface H contacting the side plate 155 ′ and being transferred sideways, The irradiation light of the optical fiber sensor 181 is reflected from the component A, and the reflection intensity is high, so that air is ejected from the air ejection hole 156 ', and the component A is blown off as indicated by a one-dot chain line and eliminated. On the other hand, as shown in FIG. 13B, when the component A is transported with the side face F in contact with the side plate 155 'and in a predetermined transport direction, the optical fiber sensor 181 reflects the light from the slope 158'. Since light is received, the reflection intensity is extremely small. In this case, since air is not ejected from the air ejection hole 156 ', the component A passes through as it is.
[0046]
As described above, the posture and the transfer direction of the component A are simultaneously selected by the second sorting unit 171 ′, and only the component A having the predetermined posture and the transfer direction is discharged from the second sorting unit 171 ′. Transferred to 191. In the discharge section 191, as shown in FIGS. 14 and 15, the inclined flat plate track 144 is changed to a horizontal transfer surface discharge track 194, and the guide plate 193 and the holding plate 196 are used to set a predetermined posture and position. Since the part A in the transfer direction is in a tunnel shape that can be transferred only in a single row and a single layer, the part A is transferred without disturbing its posture and the transfer direction and discharged from the downstream end, It is supplied to the next process via a linear vibration parts feeder whose description is omitted.
[0047]
(Example 2) Fig. 16 is a perspective view of a component D to be reconciled by a component reconciliation device 200 of Example 2, in which a prismatic main body 7 molded with black resin and a Two stainless steel leads 8 protruding sideways in parallel with the top surface J from the corner cut portion near the surface J, and a stainless steel lead rising parallel to the side surface L from the corner cut portion near the bottom surface M on the side surface L side. 9 is provided. Then, the part D is transferred in the direction shown by the white arrow in the posture shown in FIG.₁ It is desired that the transport be performed first. Because the shapes of the leads 8 and 9 are different, as shown in FIG. 16B, even when the top surface J is in the same posture as the top surface, the end surface N opposite to the one in FIG._Two Must be rejected.

The wound electromagnet 216 is provided facing the movable core 212c on the lower surface of the movable block 212 with a slight gap. The drive section 211 is covered with a soundproof cover 217 around the drive section 211, and is mounted on the substrate 219 via the vibration proof rubber 218 together with the bowl 221. When an alternating current is applied to the coil 215, the bowl 221 is subjected to clockwise torsional vibration when viewed from above. Various mechanisms attached to the bowl 221 will be described with reference to FIG.
[0051]
Referring to FIG. 20, a bowl 221 accommodates a number of components D on a bottom surface 222 (split for simplicity in FIG. 20) and a flat track having a starting point 224s around the bottom surface 222. 224 is provided spirally upward in the clockwise direction along the peripheral wall 223 of the bowl 221. The flat track 224 is formed so as to be inclined slightly downward toward the outside of the diameter of the bowl 221, and the component D is transferred in contact with the side wall 225 of the flat track 224 under torsional vibration.
[0052]
Notches 227, 228, and 229 for reducing the track width and adjusting the transfer amount of the component D are provided in the downstream portion of the flat plate track 224. A separation plate 234 for breaking D and a transfer amount adjustment block 237 are provided. Subsequently, the J groove tracks 241 and 242, and further, the air ejection holes 266, the first sorting unit 271, and the second sorting unit 271 'are discharged. A unit 301 is provided. These will be described sequentially.
[0053]
Referring to FIG. 7 of the first embodiment, the mounting bar 233 fixed with the bolt 233b to the upper stage of the two-stage notch 232 of the peripheral wall 223 is passed over the lower stage of the notch 232 for the early exit gate 231. A fast-moving gate 231 having an inner peripheral surface substantially aligned with the side wall 225 of the flat track 224 is screwed and fixed to the mounting bar 233 with a bolt 231b from the outer peripheral side. When the part D is to be pulled out from the bowl 221 in an unsteady state, for example, when the type of the part D is changed, or when the work is completed, the part D is cut off by loosening the bolt 231b and removing the quick release gate 231. It is extracted outside through the lower part of the notch 232.
[0054]
The separating plate 234 is provided in the notch 235 of the peripheral wall 223 as a plate having a thickness smaller than the thickness of the component D so that the side edge is obliquely oblique to the transport direction of the flat plate track 224 from the side wall 225, and is fixed by the holding block 236. ing. Of the components D stacked and transported, the lowermost component D is guided to the inner peripheral side by the side edge of the separation plate 234, and the components D of the second layer or more ride on the separation plate 234 and are transported in contact with the side wall 225. Therefore, the stacked parts D are broken.
[0055]
The notches 227, 228, and 229 provided in the flat track 224 narrow the track width, and adjust the transfer amount by dropping the inner peripheral part D among the parts D transferred in multiple rows. The notch 238 of the peripheral wall 223 at a position opposite to the notch 228 is formed between the notch 228 by a bolt 237b through which the transfer amount adjusting block 237 passes through a long hole 239 in the radial direction of the bowl 221 provided therein. Are mounted so that the track width can be adjusted, and the transfer amount can be adjusted.
[0056]
Referring to FIG. 21, which is a cross-sectional view taken along the line [21]-[21] in FIG. 20, the J-groove track 241 formed in an arc shape is formed in a J-shape in which the cross section is opened upward and inclined. The inner circumferential groove portion is provided at a position through a slight step downward from the flat track 224. The width of the round groove is substantially the same as the length of the part D, and the transverse part D whose longitudinal direction intersects the round groove has a predetermined center of gravity at which the position of the center of gravity becomes lower while being transferred by receiving torsional vibration. It will take the direction of transfer. As shown in FIG. 20, a notch 247 is provided on the inner peripheral side of the J-groove track 241 for dropping the component D overflowing without entering the J-groove track 241 and returning it to the bowl 221.
[0057]
Also, the J-groove track 241 has its downstream end positioned on the side surface of the upstream end of the J-groove track 242, and is connected to the J-groove track 241 via a slight step below. Since the groove track 241 and the J-groove track 242 have different transfer directions, the horizontal part D takes a predetermined transfer direction at this connection portion and also during the transfer of the J-groove track 242.
[0058]
On the downstream side of the J-groove track 242, a flat track 254 is connected via a slight step downward. Referring to FIG. 20 and FIG. 22 showing an enlarged cross section taken along the line [22]-[22] in FIG. 20, the track block 252 and the holding block 253 overlap with each other on a horizontal surface obtained by shaving the peripheral portion of the bowl 221. The flat plate track 254 is formed on the track block 252 so as to be slightly inclined downward toward the outside of the radius of the bowl 221, and a right side wall 255 is provided on the flat track 254. A cut groove 257 is provided so that the lead 8 or 9 does not contact the side surface 255 when the component D has the top surface J facing upward. As shown in FIG. 22, at the connection point, the side wall 255 is cut so as to match the inclination of the J-groove track 242 so as not to obstruct the part D transferred from the upstream J-groove track 242.
[0059]
Next, as shown in FIG. 20 and as shown by a dashed line in FIG. 22, the flat track 254 has a reduced width, and the component D having the top surface J on the upper side cuts the lead 8 or 9 into the cut groove 257. The component D with the top surface J on the lower side is brought into contact with the side surface 255, the main body 7 is slid to the inner peripheral side, and the center of gravity is flat. Since the track 254 is disengaged from the truck 254, it falls into the bowl 221 and is removed. Parts with side K facing downDThe component D with the ridge of the lead 8 and the main body 7 in contact with the flat track 254 and the side face L on the lower side is transferred with the lead 9 in contact with the flat track 254, but in any case, the main body 7 is slid inward. Are similarly dropped from the flat track 254 and removed.
[0060]
Further, referring to FIG. 23 showing a cross section taken along the line [23]-[23] in FIG. 20, in addition to the flat track 254, the side wall 255, and the cut groove 257 formed on the track block 252, the end face N₁ Or N_Two An air ejection hole 266 is provided in the restraining block 253 to eliminate a part D to be transported while standing on it. That is, a joint 268 is screwed from the outer peripheral side to an air hole 267 formed in the holding block 253, and the compressed air pipe 269 is connected to the air hole 267. An air ejection hole 266 is provided. The air ejection hole 266 is at the end face N₁ Or N_Two Is open at the height of the upper end of the component D standing on the₁ Or N_Two The part D to be transported while standing on it is blown off and eliminated. The bolt 252b fixes the track block 252 to the bowl 221.
[0061]
Although the first sorting unit 271 and the second sorting unit 271 ′ are provided on the downstream side of the air ejection holes 266, the second sorting unit 271 ′ is configured in exactly the same manner as the first sorting unit 271. The configuration will be described with reference to the first sorting unit 271. If necessary, the components corresponding to the first sorting unit 271 will be denoted by the same reference numerals with (') and the description will be omitted.
[0062]
The first sorting unit 271 refers to FIG. 24 showing a cross section taken along the line [24]-[24] in FIG. 20, and a track block 272 in which the track block 252 in FIG. A linear sorting track 274, a side wall 275 perpendicular to the straightening track 274, and a cut groove 277 as a passage for the lead 8 or 9 are formed on the pressed holding block 273. A reflection type optical fiber sensor 281 for detecting the lead 9 and a reflection type optical fiber sensor 291 for detecting the direction of transfer of the component D are attached above. The reflection type optical fiber sensor 281 and the optical fiber sensor 291 are functionally equivalent to each other in appearance, including the presence or absence of a lens barrel 292 having a built-in lens, but have the same function, and operate similarly to the reflection type optical fiber sensor 181 in the first embodiment. .
[0063]
The optical fiber sensor 281 has a threaded portion 283 screwed to a support member 279 fixed to the lower surface of the side edge of the bowl 221 with bolts 279b and fixed with set screws 283b, and the optical fiber and the track block 272 together with the jacket 282. Is inserted into the optical sensor hole 276 provided in the optical sensor.
[0064]
That is, the optical fiber sensor 281 does not operate at all when the component D does not pass.SaAnd the end face N of the parts D transferred with the top face J facing upward₁ , The side K of the component D is on the side of the optical fiber sensor 281, so that the optical fiber sensor 281 receives the reflected light from the black main body 7.Do not activate anythingIt is set as follows. On the other hand, the end face N_Two , The side face L is on the side of the optical fiber sensor 281, so that the optical fiber sensor 281 receives the high intensity reflected light from the stainless metal lead 9 in the reflected light from the black main body 7. However, only at this time, air is ejected as described later. That is, whether the component D is facing forward or backward is detected and selected.
[0065]
Further, a support member 295 is fixed on the holding block 273 with bolts 295b, and a reflection type optical fiber sensor having a lens barrel 292 having a built-in lens at a tip end in a notch of a mounting member 296 fixed to the holding block 293 by bolts 296b. The threaded portion 293 of the 291 is sandwiched, and the outside is held down by a holding plate 294 and fixed with a bolt 294b. The optical axis Q of the irradiation light of the optical fiber sensor 291 is set by removing the component D in the predetermined transfer direction. When the component D is in the predetermined transfer direction, the reflected light from the sorting track 274 is set. When the component D is in the horizontal direction, low-intensity reflected light from the black main body 7 is received, whereby the horizontal component D is detected.
[0066]
Furthermore, a compressed air pipe 289 is connected to an air hole 287 formed in the holding block 273 via a joint 288 screwed from the outer peripheral side, and a vertically downward air hole provided at the tip of the air hole 287 is provided. A horizontal air ejection hole 286 passing through a small hole is opened in the side wall 275. Then, when the lead 9 of the component D is detected by the optical fiber sensor 281 and the backward component D is detected, or when the optical fiber sensor 291 detects the component D which is lateral and is not in the predetermined transfer direction, the compressed air piping 289 is used. A non-illustrated solenoid valve is opened instantaneously, and air is blown out from the air blowout hole 286, and these parts D are blown off and removed. That is, the air ejection hole 286 is shared by the optical fiber sensor 281 and the optical fiber sensor 291. Note that the air ejection holes 286 are also opened to the outer peripheral side, in order to reduce the flow rate of air in the air ejection holes 286. This is because if the flow velocity is high, the part D may stick to the side wall 275 and may not be removed.
[0067]
A discharge section 301 is provided downstream of the second sorting unit 271 '. Referring to FIG. 27, which is a cross-sectional view taken along the line [27]-[27] in FIG. 20, and FIG. 28, which is a cross-sectional view taken along the line [28]-[28], the peripheral edge of the bowl 221 is notched. The track block 302 is fixed, and a flat transfer surface and a side wall 305 of the discharge truck 304 are formed at a position where the track block 302 is connected to the upstream sorting track 274. A guide plate 303 is mounted on the inner peripheral side of the track block 302 with screws 303b at a height for running the lead 9 of the component D in a predetermined transfer direction on the surface thereof, and is mounted on the upper surface on the side wall 305 side by a screw 303b. A holding plate 306 formed with a cut groove 307 for running the lead 8 of the component D in the direction of transfer together with the track block 302 is fixed by bolts 306b, and the discharge track 304 as a whole has a gap at the upper part on the inner peripheral side. Is substantially tunnel-shaped so that the component D can be transferred without disturbing the predetermined posture and the direction of transfer.
[0068]
Referring to FIG. 27, in the upstream portion of the discharge section 301, the lower surface of the holding plate 306 and the cut groove 307 are parallel to the inclination of the sorting track 274 so as not to hinder the part D transferred from the inclined sorting track 274. Further, a mounting member 312 is fixed on the holding plate 306 with screws 312 b on the holding plate 306, and a fitting 318 is screwed into a vertical air hole 317 formed in the mounting member 312 in a vertical direction. Compressed air piping 319 is connected. Further, an air ejection hole 316 inclined downward from the lower end of the air hole 317 toward the downstream side is provided, and air is always ejected. That is, the ejected air is blown into the discharge track 304 from the gap formed between the guide plate 303 and the holding plate 306 at the upper portion on the inner peripheral side of the discharge track 304 to push the component D. .
[0069]
The air for this pushing is applied to the end face N of the part D.₁ , N_Two Since the lead 9 is provided at a position slightly inward from the inside, the component D is prevented from being transferred slightly to the left or right in the discharge track 304 having a relatively wide width to lower the transfer speed. . Although not shown, the component D discharged from the downstream end of the discharge truck 304 is turned upside down, sent to the linear vibration parts feeder, and supplied to the next step. In the present embodiment, since the reversal of the component D is omitted from the description, the description is made with the actual top and bottom reversed.
[0070]
The component feeding device 200 according to the second embodiment is configured as described above, and the operation thereof will be described below.
[0071]
19 and 20, a large number of components D are accommodated in the bottom surface 222 of the bowl 221 and an alternating current is applied to the coil 214, so that the bowl 221 is twisted clockwise when viewed from above. It is assumed that vibrations are given, and various optical sensors in the first sorting unit 271 and the second sorting unit 271 ′ and other compressed air sources are also in operation.
[0072]
Referring to FIG. 20, component D in a random position on bottom surface 222 of bowl 221 receives a transfer force in the direction of arrow n while being moved to the peripheral portion by the centrifugal force of torsional vibration, and receives flat plate track 224 from starting point 224s. Is transferred in contact with the side wall 225 while the posture and the direction of the transfer are undefined.
[0073]
The part D is transported along the flat track 224 and reaches the rapid-moving gate 231. In a normal state, the component D is transported in contact with the inner peripheral surface of the rapid-moving gate 231 substantially aligned with the side wall 225, and passes through as it is. In addition, since the track width of the flat track 224 is narrowed by the notch 227 immediately downstream of the gate 231, the part D on the inner peripheral side among the parts D that are excessively transferred in a multi-row manner is provided. Falls into the notch 227, and the transfer amount of the component D is adjusted. The component D that has fallen into the notch 227 is transported in the notch 227, and falls from the downstream end to the bottom surface 222 and returns.
[0074]
The component D that has passed through the outer peripheral side of the notch 227 reaches the separation plate 234, and among the components D that are stacked and transferred, the lowermost component D is guided to the inner peripheral side along the separation plate 234, and Since the parts D above the eye ride on the separation plate 234 and are transported in contact with the side wall 255, the stacked parts D are broken.
[0075]
The part D further reaches a notch 228 similar to the notch 227 on the upstream side, and the transfer amount is adjusted by the narrowed flat track 224. The transfer amount adjustment block provided opposite the notch 228 The track width is adjusted by sliding the 237 inward in the radial direction of the bowl 221, so that the transfer is performed with the most preferable transfer amount.
[0076]
Subsequently, the component D is transported on the outer peripheral side of the similar notch 229, and moves from the downstream end of the flat track 224 to the J-groove track 241 via a small step as shown in FIG. Then, during the transfer of the component D in the round groove portion of the J-groove track 241, the component D takes a direction in which the position of the center of gravity decreases, that is, a predetermined transfer direction. During this time, the part D that overflows without entering the J-groove track 241 falls into the notch 247 on the inner peripheral side, is transported in the notch 247, and falls back into the bowl 221 from the downstream end thereof.
[0077]
Also, the part D moves from the J-groove track 241 to the J-groove track 242 having a different transfer direction. At this connection point, and during the transfer of the subsequent J-groove track 242, the part D is not in the predetermined transfer direction. Takes a predetermined transfer direction. Therefore, at the downstream end of the J-groove track 242, the component D is transferred to the downstream flat track 254 almost in a predetermined transfer direction while the orientation of the component D is indeterminate.
[0078]
Referring to FIG. 20 and FIG. 22, although the side wall 255 is cut off at a place where the flat track 254 is connected through a slight step from the J groove track 242 downward, the part D moves smoothly. As shown by a chain line in FIG. 22, on the downstream side, the side wall 255 is perpendicular to the flat track 254 and the width of the flat track 254 is reduced. Therefore, the component D with the top surface J facing upward is transported by inserting the lead 8 or 9 into the cut groove 257, but the component D in other positions is moved by the presence of the lead 8 or 9 on the flat track 254. It is moved to the inner peripheral side, loses its balance, falls into the bowl 221 and is removed. The end face N₁ Or N_Two If there is a part D to be transferred while standing on23As shown in the figure, the guide block 253 is extended to the inner peripheral side and is moved to the inner peripheral side, and is constantly ejected from the air ejection hole 266 opened at a position corresponding to the upper end of the component D. It is blown away by the air that is being eliminated.
[0079]
In this manner, after the air ejection hole 266, the component D has the top surface J on the upper side and the lead 9 on the inner peripheral side, and the lead 9 on the outer peripheral side. 270. That is, referring to FIG. 24, the component D is detected by the optical fiber sensor 281 of the reflection type from the outer peripheral side while detecting the presence or absence of the lead 9 on the side face L while being transferred on the sorting track 274 following the flat track 254.₁ D or the end face N_Two , That is, the direction of the side surface L (or K) is detected, and whether the component D is in the predetermined transfer direction or the horizontal direction is detected by the reflective optical fiber sensor 291 from above. Is detected, and any part D that is not as specified is blown off by the air that is instantaneously ejected from the air ejection holes 286 and eliminated.
[0080]
Details of the selection of the direction of the side surface K (or L) at this time are shown in FIG. 25 which is a partially broken arrow view in the [25]-[25] line direction in FIG. FIGS. 25A and 25B are the same views, but the lead 9 of the component D is detected from the optical sensor hole 276 of the optical fiber sensor 281 opened on the side wall 275 of the sorting track 274 following the flat track 254. When the component D faces the side surface L toward the optical fiber sensor 281, air is instantaneously ejected from the air ejection hole 286 following the compressed air hole 287. That is, in FIG. 25, the component D is transported from the left to the right. However, as shown in FIG. Since the reflected light only from the black color of K is received, no air is ejected from the air ejection hole 286, and the component D passes as it is. On the other hand, as shown in FIG. 25B, when the component D has the lead 8 on the inner peripheral side and the lead 9 on the outer peripheral side, the optical fiber sensor 281 detects the reflected light from the black side surface L. The component D in the rearward direction is detected by receiving the reflected light of high intensity from the stainless steel electrode 9 and the air is instantaneously ejected from the air ejection hole 286, and the component D is blown off as indicated by the dashed line and eliminated. Is done.
[0081]
Further, details of the selection of the transfer direction are shown in FIG. 26 which is a partially broken plan view along the line [26]-[26] in FIG. FIG. 26 is a view of the same portion as FIG. 25 from a different angle, and FIG. 26A and FIG. 26B are views of the same portion. The irradiation point S of the optical fiber sensor 291 is set from above for the component D transferred along the line 275, and the direction of the transfer of the component D is set.ofDetection is performed. When the component D is in the horizontal direction and is not in the predetermined transfer direction, the component D is blown off by air instantaneously ejected from the air ejection holes 286 and is eliminated. That is, in FIG. 26, the component D is transported from the left to the right. However, when the component D is in the horizontal direction as shown in FIG. Since the small reflected light is received, air is instantaneously ejected from the air ejection hole 286, and the part D is blown off and removed as shown by a dashed line. On the other hand, as shown in FIG. 25B, when the component D is in the predetermined transfer direction, the optical fiber sensor 281 receives the reflected light with high intensity from the sorting track 274. In this case, The air is not ejected from the air ejection holes 286, and the component D passes through as it is and is transferred to the downstream side. As described above, in the first sorting unit 271, the posture and the transfer direction of the component D are simultaneously selected, and the component D having the predetermined posture and the transfer direction is transferred to the second sorting unit 271 ′ on the downstream side. You.
[0082]
The operation of the second selection unit 271 'is exactly the same as the operation of the first selection unit 271. That is, the same sorting means are arranged in series in order to improve the sorting accuracy. Therefore, the description of the operation is omitted.
[0083]
The component D having the predetermined posture and the transfer direction that has passed through the second sorting unit 271 ′ is transferred to the discharge unit 301. In the upstream part of the discharge part 301, as shown in FIG. 27, the lower surface and the cut groove 307 of the tip part of the holding plate 306 are formed so as not to hinder the part D which is inclined and transferred from the upstream sorting track 274. Since the part D is cut, the part D is smoothly transferred to the horizontal discharge track 304 of the discharge part 301, and further, the air for boosting is pushed from the air ejection hole 316 provided downward from the upper side toward the transfer direction. Are always blown out, and are blown from a gap provided between the guide plate 303 and the holding plate 306.
[0084]
Further, as shown in FIG. 28, in the downstream part of the discharge part 301, a gap into which air is blown is left in the upper part on the inner peripheral side, and the discharge track 304 formed into a tunnel by the guide plate 303 and the holding plate 306 is fixed to a predetermined position. The part D, which is the attitude and the direction of the transfer, is transferred in a single row and a single layer while being pushed by the blown air without being disturbed in the attitude and the direction of the transfer, and is discharged from the downstream end. Next, the component D is turned upside down, though not described, and then supplied to the next step via the connected linear vibration parts feeder.
[0085]
The embodiments of the parts feeding device according to the present invention have been described above. However, needless to say, the present invention is not limited to these, and various modifications can be made based on the technical spirit of the present invention.
[0086]
For example, in the first embodiment, the transmission type optical sensor 161 ′ is used to detect the vertical orientation of the component A, and the reflection type optical fiber sensor 181 is used to detect the transfer direction.Hug,A transmission type optical sensor is provided in place of the reflection type optical fiber sensor 181, and the light emitting element of the transmission type optical sensor is changed to the light receiving element by the protruding portion from the selection track 154 of the part A whose longitudinal direction is orthogonal to the selection track 154. The incoming light beam may be blocked to detect an irregular transport direction..
[0087]
In the first embodiment, for the component A having the gap g between the sorting track 154 and the bottom surface G, the top and bottom postures of the component A are detected using the gap g as the optical path of the transmission optical sensor 161.
