A slope track 336 and an inner peripheral wall 337 aligned with the upstream slope track 326 and the inner peripheral wall 327 are provided. In addition, a long hole 339 is provided in the inclined track 336 leaving a width in which the parts M are transferred in a single row on the inner peripheral wall 337 side, and the parts M transferred in two rows fall from the long holes 339 and are dropped into the bowl. 321 is returned. In this way, the part M is surely made into a single row when it passes through the derivation block 332.
[0008]
Returning to FIG. 21, following the derivation block 332, an arc-shaped track block 342 is provided. Referring to FIG. 25, which is a cross-sectional view taken along the line [25]-[25] in FIG. 342 is fixed to the block support plate 331 by a bolt 342b, and has an inclined track 346 formed of an inclined surface aligned with the inclined track 336 of the lead-out block 332. Further, the inner peripheral wall plate 344 is held between the holding member 343 by screws 344b inserted from the outer peripheral side to the inner peripheral side. The inner peripheral wall plate 344 is long in the range of the central angle of 105 degrees and has a height corresponding to the thickness of one component M, but has a long hole 345 and can be adjusted in the vertical direction. The height is adjusted according to the type of the part M. When there is a part M that is transported in multiple layers on the slope track 346, the upper part part M gets over the inner peripheral wall plate 344 and falls onto the block support plate 331, and the part M is made into a single layer.
[0009]
At the downstream end of the track block 342, referring to FIG. 26 which is a cross-sectional view in the [26]-[26] line direction in FIG. 21, the boundary between the slope track 346 and the inner peripheral wall 347 is gradually lowered. A V-groove 348 having an opening angle of 90 degrees is formed by digging down and comprising an inclined surface 348a and an inclined surface 348b. Accordingly, the part M transferred while the slope track 346 is brought into contact with the inner peripheral wall 347 is tilted to the slope 348b and transferred to the front / back correction block 352 connected thereto. Referring to FIG. 27 showing a cross section in the [27]-[27] line direction in FIG. 21, the front and back correction block 352 has an inclined surface 358 b having an angle aligned with the inclined surface 348 b of the upstream V groove 348 and the diameter of the bowl 321.

Further, an air ejection hole 355 is opened on the inclined surface 358b at a position on the upper end surface portion of the component M to be transferred, and air from the compressed air pipe 359 inserted and screwed from the lower surface of the block support plate 331 is received. Erupted.
[0011]
When the intensity of the reflected light is high, the optical sensor 356 detects that the part M is facing up and the air is not ejected from the air ejection hole 355 and the part M is transferred as it is, but when the intensity of the reflected light is small, Since the part M is detected as being face-down, and air is instantaneously ejected from the air ejection hole 355, the part M is reversed toward the inclined surface 358a and turned face-up. The square groove 357 is provided to facilitate this inversion. That is, the part M is tilted to one of the slopes 358a and 358b of the front / back correction block 352 and transferred face up.

That is, the parts M on the slopes 368a and 368b are all collected on the joining surface 369 and transferred downstream from the joining block 362.
[0014]
As shown in FIG. 21, a transfer block 372, a sorting block 382, and a transfer block 392 are sequentially connected downstream of the merge block 362. Similar to the transfer block 392, the transfer block 372 is formed with an inclined track 374 that faces the outside of the diameter of the bowl 321 and has an upward inclination angle of 15 degrees, but has a cross section similar to that shown in FIG. The explanation is made in the transfer block 392.
[0015]
The sorting block 382 downstream of the transfer block 372 is fixed to the block support plate 331 by bolts (not shown) with reference to FIG. 29 showing a cross section in the [29]-[29] line direction in FIG. An inclined track 384 and an inner peripheral wall 387 aligned with the flat track 374 in the transfer block 372 are provided. Further, a support column 388 is erected on the outer peripheral portion thereof, and a sensor support 386s is fixed to the column 388b by a bolt 388b, and an optical sensor 386 is attached to the tip end portion thereof. The optical sensor 386 monitors the front and back of the component M transferred in contact with the inner peripheral wall 387. The optical sensor 386 is configured and operates in the same manner as the optical sensor 356 in the front / back correction block described above.

A hole 385b is opened to the slope track 384 side, and compressed air pipes 389a and 389b inserted and screwed from below the block support plate 331 communicate with each other. When the optical sensor 386 detects the backward component M, air is simultaneously ejected from the air ejection holes 385a and 385b, so that the backward component M is ejected. _Four Is blown off onto the block support plate 331 as indicated by an arrow and eliminated.
[0017]
A transfer block 392 is connected downstream of the sorting block 382. Referring to FIG. 30, which shows a cross section in the [30]-[30] line direction in FIG. 21, the transfer block 392 has a bolt 392b at the outer periphery. The inclined track 394 and the inner peripheral wall 397 provided on the block support plate 331 are aligned with the inclined track 384 and the inner peripheral wall 387 in the upstream sorting block 382. 21, the part M removed to the block support plate 331 is transferred to the downstream side, guided to the guide plate 333 provided at the downstream end, and returned to the bowl 321. In the above description, the derivation block 332 and the front / back correction block 352 are replaced according to the size type of the part M.
[0018]
A linear vibration part feeder 400 that individually feeds parts M is connected to the downstream end of the transfer block 392. This is basically the same as the linear vibration part feeder 200 in the embodiment, and will be described in the embodiment. The description here is omitted.
[0019]
The torsional vibration parts feeder 300 in the conventional component feeding apparatus 20 is configured as described above. Next, the operation thereof will be described.
[0020]
Referring to FIG. 21, the part M accommodated in the bottom surface 322 of the bowl 321 is subjected to torsional vibration and is moved to the peripheral portion and is transferred in the direction indicated by the arrow n to form a shallow curved surface track 324 in cross section. get on. On the curved track 324, the parts M are transported in multiple layers and in multiple rows with the front and back being indefinite, but referring to FIG. 22, the notches 325 are reached, leaving 2-3 rows of parts M, and the inner peripheral parts. M falls and returns to the bottom surface 322 of the bowl 321 to adjust the transfer amount.
[0021]
A slope track 326 shown in FIG. 23 is transported from directly downstream of the notch 325, but a low inner peripheral wall 328 in which the height of the inner peripheral wall 327 is lowered. ₁ 328 ₂ 328 _Three The parts M stacked in step S1 slide down and are returned to the bottom surface 322, so that the parts M are formed into a single layer. In addition, a long hole 329 provided along the peripheral wall 323. ₁ 329 ₂ In FIG. 5, the part M transferred in contact with the inner peripheral wall 327 passes as it is, but the part M transferred in two to three rows falls and returns to the bottom surface 322 to be made into a single row.
[0022]
Next, the part M is led out to the outside of the bowl 321 through the lead-out block 332, but referring to FIG. 24, the slope track 336 is narrowed to one width of the part M by the long hole 339 of the lead-out block 332. The part M is completely made into a single row by passing through.
[0023]
Subsequently, the part M is transported on the slope track 346 shown in FIG. 25, and is transported in contact with the long inner peripheral wall plate 344 whose height is adjusted to one thickness of the part M, so that a multilayer part is obtained. M slides down and is removed onto the block support plate 331, and the component M is completely made into a single layer.
[0024]
The part M is tilted and transferred to the slope 348b of the V groove 348 of FIG. 26 provided at the downstream end of the slope track 346, and is then tilted and transferred to the slope 358b of the V track 358 in the front / back correction block 352 of FIG. However, during this time, the front and back sides are detected by the optical sensor 356. In other words, the front-facing component M passes through as it is, but when the back-facing component M is detected, air is instantaneously ejected from the air ejection holes 355, and the component M is inverted toward the inclined surface 358a and turned face-up. . That is, the part M is transferred to the downstream confluence block 362 in the face-up direction on either the slope 358a or the slope 358b.
[0025]
In the confluence block 362, the part M is transported with the slopes 368a and 368b of the ship bottom track 368 shown in FIG. 22 facing the upstream slopes 358a and 358b. And are transferred to the sorting block 382 of FIG. 29 via the slope track 374 of the transfer block 372.
[0026]
In the sorting block 382, the front and back sides of the parts M transported by contacting the inclined track 384 with the inner peripheral wall 387 are monitored by the optical sensor 386, and the front-side parts M pass through as they are, but the back-side parts M are detected. In such a case, air is instantaneously ejected from the air ejection holes 385a and 385b at the same time, and the component M facing back is blown off and removed onto the block support plate 331. The component M on the block support plate 331 is guided to the guide plate 333 at the downstream end thereof and returned into the bowl 321.
[0027]
The part M that has passed through the sorting block 382 is transferred to the inclined track 394 in the transfer block 392 of FIG. 30 and is transferred to the linear vibration parts feeder 400 connected to the downstream end thereof.
[0028]
[Problems to be solved by the invention]
The conventional component feeding device 20 is configured and operates as described above, but has the following disadvantages. In other words, the conventional parts feeding device 20 has the ability to feed 40 parts M per minute. For example, to improve this to 80 sheets per minute, for example, the torsional vibration amplitude is reduced to 0. When the size is increased from 4 mm to 0.6 mm, there may be a case where the front and back are reversed during the transfer. Even though the front and back straightening blocks 352 are arranged to face up, the downstream boat bottom track 368 and the slope track 374 cause inversions, and the number excluded by the sorting block 382 increases, and the sorting block 382 faces down. Despite the removal of the part M, it was not possible to achieve the target improvement in the feeding performance, for example, a part that was reversed at the downstream slope track 394 was generated.
[0029]
Accordingly, the present invention provides a component feeding device having an improved transfer capability without increasing the transfer amount of an elongated plate-like component by increasing the amplitude of torsional vibration, so that the component is not reversed on the track in the middle of transfer. Is an issue.
[0030]
[Means for Solving the Problems]
The above problem is that a bowl in which a spiral track is formed is torsionally vibrated so that an elongated plate-like component is supplied to the next process in a single layer and a single row with the longitudinal direction in the transfer direction. In the component feeder, the uppermost portion of the track has an arc-shaped track portion having a semicircular or U-shaped cross section, and an upstream end portion of the arc-shaped track portion, or of the arc-shaped track portion. A downstream section of the arc-shaped track section including a V-shaped linear track section connected to the upstream end section and the downstream end section, and connecting the linear track section to the downstream end section. In the portion, a V-groove having a V-shaped cross section is formed in a gradually increasing depth, and the radially outward slope of the V-groove is aligned with the radially outward slope of the linear track portion. This is achieved by a component feeder. In this configuration, the elongated plate-like component is transferred on the transfer surface by four-point support in the arc-shaped track portion. Therefore, it is transported by torsional vibration more stably than in the case of conventional three-point support, that is, without reversing the front and back, and is used for single row, single layer, front and back sorting, front and back correction, etc. After being subjected to a predetermined alignment action, the straight track portion can be reliably guided to the straight track portion, and in some cases, the straight track portion is guided to an arc-shaped track portion having the following similar cross-sectional shape. Then, it is guided to the downstream side under other or similar alignment action. Therefore, regardless of any alignment action, the supply efficiency can be improved as compared with the prior art because it is supplied to the next process without disturbing the alignment state.

When the coil 215 is energized, a linear vibration in the direction indicated by the arrow p is applied to the trough 221.
[0067]
The trough 221 is a groove formed by digging the trough block 222 with reference to FIG. 19 which is a plan view thereof, FIG. 20 which is a cross-sectional view in the [20]-[20] line direction in FIG. The transfer surface has a downward inclination angle of 3 degrees toward the downstream side and a downward inclination angle of 15 degrees toward the bowl 21 side. As shown in FIG. 18, the width of the trough 221 is determined by a side wall 223 b provided on the trough block 222 and a wall plate 223 b attached to the trough block 222 in order to facilitate the transition from the torsional vibration parts feeder 100. The width of the two or more parts M is set to be a width, but after the midstream portion, as shown in FIG. 20, the width of the parts M is transferred only in a single row, and both side walls 221a and 221b are 1 of the parts M. The height corresponds to the thickness of the sheet, and the stacked parts M are easily slid down to the bowl 21 side.
[0068]
In the midstream portion of the trough 221, an insertion hole 227 is drilled upward from the side surface of the trough block 222 as shown in FIG. 20, and an optical sensor 226 screwed to the bracket 224 is inserted and fixed. An optical path hole 225 is provided so as to open from 227 to the transfer surface of the trough 221. The optical sensor 226 is of the same type as the optical sensor 101 in the front / back correction block 92 described above, and monitors the front and back of the part M passing over the optical path hole 225. In addition, when the back sensor M is detected by the optical sensor 226, a compressed air pipe 228 for removing the component M is inserted and screwed into the bracket 224, and leads to the insertion hole 227 of the optical sensor 226. Erupt air. That is, the optical path hole 225 is also used for air ejection. Further, dust from the optical sensor 226 is also removed by this air ejection.
[0069]
Further, on the downstream side of the optical sensor 226, a nozzle mounting member 232 is fixed to the side surface of the bracket 224.

The air ejection nozzles 231 and 234 are both directed at a right angle to the trough 221 and are provided to blow away and remove any parts M that are transported by stacking the troughs 221. Note that the air ejection nozzle 231 also functions as auxiliary air in the case of removing the component M facing backward. The removed part M falls from the receiving plate 238 onto the reflux plate 208 and is returned into the bowl 21 through the opening 28 in the peripheral wall 23 of the bowl 21 shown in FIG. A member 239 provided on the downstream side of the trough 221 is for attaching a trough cover when necessary.
[0070]
The component feeder 10 according to the embodiment of the present invention is configured as described above, and the operation thereof will be described next.
[0071]
In FIG. 2, the component M accommodated in the bottom surface 22 of the bowl 21 is subjected to torsional vibrations and is moved to the peripheral portion and transferred in the direction indicated by the arrow m, and gets on the flat track 24 from the starting point 24s. If the parts M are excessive while being transported on the flat track 24, they fall from the notch 25 and are adjusted to an appropriate amount. The part M is lifted up to the uppermost round part on the flat track 24, and is transferred to the round track 44 of the track block 42 laid outside the bowl 21 through the lead-out block 32 shown in FIGS. The component M is transferred to the outer peripheral side from the center line of the round groove track 44, that is, from the bottom of the round groove track 44, due to the component of the transfer force of the torsional vibration toward the outside of the bowl 21. At this time, the parts M are multi-layered and multi-rowed with the front and back being indefinite, and the parts M crowded by the air ejected from the air ejection nozzle 39 shown in FIGS.
[0072]
At the downstream end of the round track 44, the component M is sent to the L-shaped track 54 of the first alignment block 52 via the shallow groove 46 that is mainly transferred to the inclined surface 45b of the V groove 45 and can be transferred in a single row. However, it is inclined and transferred to the inclined surface 54b. As shown in FIG. 9, the width of the inclined surface 54a is slightly wider at the upstream end portion, but since it is a width corresponding to the thickness of two parts M indicated by the broken line from the immediately downstream side, it is stacked to have three or more layers. A certain part M cannot be supported by the inclined surface 54a and falls onto the block support plate 31 to be eliminated. That is, by passing through the first alignment block 52, the parts M are roughly aligned in a single row or a double row with a maximum of two layers. The component M that has dropped onto the block support plate 31 is the guide plate 37 shown in FIG. ₁ Is returned to the uppermost round of the flat track 24 in the bowl 21.
[0073]
The part M that has passed through the first alignment block 52 is transferred to the round track 64 of the subsequent track block 62. At the time of this transition, if there is a part M that is jammed by the air ejected from the air ejection nozzle 59 shown in FIG.
[0074]
At the downstream end of the round track 64, the component M is mainly transferred to the inclined surface 65b of the V-groove 65, and the shallow groove 66 to which the component M can be transferred only in a single row provided on the inclined surface 65b. Then, it is sent to the L-shaped track 74 of the second alignment block 72.
[0075]
12 and 13, the inclined surface 74b of the L-shaped track 74 is the bottom surface of a groove formed so that the part M can be transferred only in a single row. Some of them are inclined to the slope 74a, but these are blown up by the air ejected from the air ejection nozzle 69 and reversed to the slope 74b. Further, the width of the slope 74a is slightly wide at the upstream end, but is cut as shown by the broken line from the immediate downstream, and is a width corresponding to the thickness of one piece of the part M. Therefore, the parts stacked in two or more layers M cannot be supported by the inclined surface 74a but falls onto the block support plate 31 and is eliminated. That is, the part M passes through the second alignment block 72, so that it is completely made into a single layer and made into a single row.
[0076]
The part M that has passed through the second alignment block 72 is transferred to the round truck 84 of the track block 82. At this time, the part M that is jammed by the air blown from the air jet nozzle 79 is separated and transferred. Can be helped.
[0077]
The part M is transported through the round track 84 in a single-layer, single-row state, reaches the downstream end, and is tilted and transported to the inclined surface 85b of the V-groove 85, so that the V-shaped track 94 in the front / back correction block 92 of FIG. It is sent to the slope 94b. As shown in FIG. 16, when the component M passes over the optical path hole 103 opened in the inclined surface 94b, the lower and upper optical sensors 101 detect the front and back of the component M from the intensity of the reflected light. When the optical sensor 101 detects the back-facing part M, air is instantaneously ejected from the two air ejection holes 96 provided on the slope 94b, and the back-side part M is reversed to the slope 94a side and transferred face-up. Is done. That is, the part M passes through the front / back correction block 92 and is tilted face-up on either the slope 94a or the slope 94b and is transferred to the downstream side.
[0078]
The part M that has passed through the front / back correction block 92 abuts on the guide member 115 attached to the track block 112, that is, the part M from the slope 94b abuts on the back surface, and the part M from the slope 94a abuts on the side surface. However, during this time, the part M is transported without being changed in posture by being suppressed by the air ejected from the air ejection nozzle 119. Then, when the rear end of the part M passes over the optical path hole 103, the part M is transferred to the round track 114 through a small step. As described above, the arc-shaped track block 112 connected to the downstream side of the front / back correction block 92 is set to be shorter than the other arc-shaped track blocks 42, 62, and 82, and the track block 112 has a half cross section. Since the circular round track 114 is formed, the part M is stably transferred in contact with the transfer surface of the round track 114, so that the front and back sides after the front and back correction blocks 92 are arranged face up. Are fed into the linear vibration parts feeder 200 without causing reversal of the above.
[0079]
In the linear vibration parts feeder 200, the part M from the upstream round truck 114 is transferred to the wide upstream part of the trough 221. The air is ejected from the air ejection nozzle 128 provided in the upstream track block 112 toward this location, so that the trough 221 in which the part M is smoothly made the width of the single row of the parts M without overlapping. It is sent to the midstream part. At the midstream portion, as shown in FIG. 20, the optical sensor 226 monitors the front and back of the part M passing over the optical path hole 225 opened on the transfer surface of the trough 221. When the part M facing back is detected. Air is instantaneously blown from the compressed air pipe 228, ejected from the optical path hole 225, and assisted by the air from the air ejection nozzle 131, the back-facing component M is removed to the receiving plate 238.
[0080]
Further, when there is a part M that is transported while being stacked in the trough 221, the side wall 221 a of the trough 221 is set to the same height as one of the parts M, and the air ejection nozzle shown in FIGS. 19 and 20. Since the air from 231 and 234 is ejected from the side, it is easily blown off and removed toward the receiving plate 238. In this way, the part M arranged in a single layer, single row and facing up is discharged from the downstream end of the trough 221 of the linear vibration parts feeder 200. The part M removed to the receiving plate 238 is returned to the flat plate track 24 in the bowl 21 of the torsional vibration parts feeder 100 through the reflux plate 208.
[0081]
In the embodiment of the present invention, the first alignment block 52 and the second alignment block 72 each perform the single layer formation and single row formation of the component M. The singularization may be performed independently.
[0082]
Further, in the embodiment of the present invention, the component M is made into a single layer, a single row, and the front and back are made constant, but the component arrangement of the present invention is also performed when only the single layer and the single row are made. The feeding device applies as well.
[0083]
As described above, according to the present invention, the substantially circular block support plate 31 includes a plurality of pairs of arc-shaped track portions and linear track portions as the uppermost track portion. In addition, V-shaped grooves 45, 65, and 85 each having a V-shaped cross section that gradually increases in depth toward the transfer direction are respectively provided at the downstream ends of the round troughs 44, 64, and 84 serving as arc-shaped track portions. The parts M are formed along the radially outward slope, and the first track 52, the second alignment block 72, and the straight track portion of the front / back correction block 92 on the downstream side connected thereto are connected. In the linear track portion, a predetermined alignment action is performed in these linear track portions, that is, in the first alignment track 52 on the most upstream side, for example, three layers are reduced to two layers, and the flow rate downstream is reduced. And then After the two alignment blocks 72a are made into a single layer and a single row, all are turned to the front in the front and back correction block 92, and then supplied to the next process through the last arc-shaped track portion 114, so Only the parts M are supplied in a single layer and in a single row, and the parts M which have not been subjected to a predetermined alignment action at the linear track portions on the block support plate 31 to which a plurality of pairs of arc-shaped track portions and linear track portions are attached. Are all dropped here, and after obtaining a transfer stroke within 360 degrees, each guide plate 37 ₁ , 37 ₂ As a result, the spiral track portion is returned directly below the bowl body. Moreover, the downstream guide plates 37 are introduced so as to be immediately introduced into the start ends of the plurality of pairs of arc-shaped track portions and straight track portions. ₂ Thus, it is guided to the vicinity of the discharge end of the spiral track of the bowl body. Accordingly, in the conventional examples other than the conventional example shown in the drawing, the parts M are generally raised as a group of flat tracks formed in a spiral shape on the inner peripheral wall surface of the bowl. Even if it is introduced into the uppermost track part after that, as described above, the parts that are turned front and back by three-point support with the transfer surface are face-down. However, according to the present invention, it is possible to reliably supply an elongated plate-like component M as shown in FIG. 1 in a single-layer, single-row, face-up orientation, and to perform some sort of alignment. Since the part dropped from the linear track part is guided again to the uppermost part by the rotation by the torsional vibration of 360 degrees or less, the supply efficiency to the next process can be improved much more than before. Note that the part M as clearly shown in FIG. 1 is a part that is very easily entangled. When a large amount of the part M is placed on the center bottom of the bowl from above, the part in the entangled state increases, leading to the uppermost track part. It may fall almost before being broken. Therefore, the amount of bowl input is limited to a certain amount, that is, if the remaining amount of parts at the center bottom of the bowl does not fall below the amount, there is almost batch input by the robot. In the past, the feeding speed of the batch type robot was large because the supply speed to the next process of the parts was small, and according to the present invention, this interval was reduced. The production efficiency can be greatly increased as compared with the prior art.
[0084]
In addition, V grooves 45, 65, and 85 are formed on the downstream side of the round track 44, 64, and 84. Of the pair of slopes, the slope outside the diameter of the bowl is caused by the torsional vibration of the bowl. Although it is certain that the centrifugal force is greatly involved, the operation principle will be further described with reference to FIG. 31 as follows.
[0085]
Although the dimensional ratio and the shape are greatly different from those of the drawings showing the embodiments, this is for easy understanding of the principle. In the bowl body B shown schematically, a spiral track T is shown as is known in the art, but at the discharge end, a track corresponding to the aforementioned lead-out block 32 as a linear track portion. The part t is connected to the circular track part Q corresponding to the round track 44, 64 and 84 of the above embodiment. ₁ , Q ₂ , Q _Three Is connected. These are shown in extreme exaggeration, but first of all Q ₁ Is the center O of the bowl as shown (this is also exaggerated, but is actually in bowl B) at a biased position O ', and the radius of bowl B around this A radius r smaller than R is formed, and each downstream side end portion corresponds to each alignment block as a linear track portion corresponding to J. ₁ , J ₂ Is connected, but this linear alignment track J ₁ , J ₂ Is formed so as to be on a circumference concentric with the center O of the bowl B (this is also exaggerated). The second downstream arcuate track portion Q ₂ The center O ″ of the bowl B is also the center O of the bowl B and the arcuate track portion Q on the upstream side. ₁ The radius r is at the position O ″ deviated from the center O ′, and the radius r thereof is the upstream arc-shaped track portion Q. ₁ Is identical to that of
[0086]
Each arc-shaped track portion Q ₁ , Q ₂ A V-shaped groove having a V-shaped cross section and gradually increasing in depth toward the downstream side, ₁ , V ₂ Is formed. In the bowl B, the part M receives the torsional vibration force on the track T and reaches the linear discharge track part t. ₁ The curvature is large, and it is transferred by receiving a torsional vibration force at a four-point support here. As is clear from the figure, the torsional vibration of the bowl B is an arc-shaped vibration around its center O. Therefore, the first arc-shaped track part Q ₁ Since the curvature is different in the extending direction of the V groove V ₁ , V ₂ Then, as indicated by a thin line W, this indicates a tangential line of a concentric circumference of the center O of the bowl B. ₁ The center G of the part M receives a transfer force due to vibration. For this reason, as described above, the V-groove V ₁ , V ₂ Of the slopes forming the rim of the bowl are transferred toward the slopes outside the bowl diameter, and the straight track part J described later is transferred. ₁ , J ₂ It can be accurately transferred to the outer diameter side slope and subjected to a predetermined alignment action. Although not shown, this round track Q ₁ , Q ₂ As is apparent from the direction of the tangent W when the radius of the bowl is larger than the radius R of the bowl, the arc-shaped track portion Q is received as a vibration transfer force. ₁ , Q ₂ Depending on the size of the radius of the straight track portion J, the straight track portion J is transported along the slope on the inner diameter side and connected to the slope. ₁ , J ₂ The cross section is also formed in a V-shaped cross section, but it is led to the slope on the radially inner side, and in the above-mentioned embodiment, all the places where flow restriction is desired will fall, and further on the downstream side Straight track J ₂ Then, it becomes impossible to supply in a single layer and a single layer with a single layer and a single layer, and the downstream side front and back straightening track portions face up.

【The invention's effect】
The present invention is implemented in the form as described above, and has the effects described below.
[0088]
The arc-shaped track laid along the peripheral wall of the bowl of the torsional vibration parts feeder has a semicircular or semi-elliptical cross section so that the long and slender plate-shaped parts are stably transferred in contact with the transfer surface, There is no need for parts to be turned upside down after trimming the front and back and removing parts that are not in the specified orientation, so it is not necessary to return the flipped parts back into the bowl. Is greatly improved.
[0089]
Further, in the component single layering means, single row forming means, surface stabilizing means, etc., the selection is performed with high accuracy by using a linear planar track in which the components are in surface contact and the dimensions can be easily narrowed.
[0090]
Further, as described above, the arc-shaped track portion for transferring the elongated parts and the linear track portion for performing a predetermined alignment action are continuously formed on the uppermost step portion. 31 extends within 360 degrees, but the parts not aligned on it are dropped, and the guide plate 37 is rotated by 360 degrees or less. ₁ , 37 ₂ Since it can be guided to the downstream end of the uppermost stage in a short time, the supply efficiency to the next process can be significantly improved as compared with the prior art.
[0091]
Further, in the above embodiment, the flow rate is decreased sequentially from the upstream side, and the straightening track is subjected to the straightening operation at the most downstream side as a single row and a single layer. Since the part is also arc-shaped and is supplied to the next process with four-point support, it is possible to reliably supply the elongated part M to the next process in a single layer and a single row in the front direction.
[0092]
Although not described clearly in the above embodiment, the part M introduced into the slope on the outer side of the part is detected by the front / back detection means in the part front / back correction part, Although the air jet power is used to invert the slope on the radially inward side, such parts front / back detection means have been previously developed by the present applicant. The configuration of the present invention can be used to reliably guide M. That is, as described above, all the components can be tilted on the inclined surface on the radially inner side of the V-groove formed on the downstream side of the arc-shaped track portion. Can lead to sure.
