In the path that workpiece 9 will pass through, have path R 1 as the 1st transport path 31, as parallel with path R 1 and be located at the path R2 of throughput direction top side of middle the transport path 32 in the way of throughput direction and end side path R3, reach the path R4 as the 2nd transport path 33.The part of path R2 in the middle transport path 32 forms linearity, and still, the part of path R 3 forms along with coming end side to be reversed along the clockwise direction among the figure gradually.In the middle of being located at by the path R3 that will so reverse on the part of transport path 32, can make between path R2 in the different middle transport path 32 of opening direction and the 2nd transport path (path R4) continuous smoothly.Therefore, path R2～path R4 forms continuous smoothly.In addition, path R1 and path R4 as described above can be at fluidic junction 34(with reference to Fig. 3) locate closely gradually, and finally become a path R1.
And the one-sided air squit hole 64 that is provided with a part that consists of force application part 6 in two faces of the inwall that consists of the 1st transport path 31 can make the direction ejection of air from air squit hole 64 to middle transport path 32.
Predominating path among above-mentioned path R1～path R4 be as the 1st transport path 31, along the continuous path R1 of throughput direction.Along throughput direction (the W direction among the figure) in the posture of the mobile workpiece 9 of the path R1 situation different from the benchmark posture, apply application force by the force application part 6 that has used air to this workpiece 9, while make workpiece 9 to move to the mode conversion posture of rotating on the R2 of path.Particularly, thereby this force application part 6 can be by applying application force by 64 pairs of workpiece of air squit hole, 9 ejection air to workpiece 9, and this application force is by the spray volume control of air pressure and air.Under the effect of such application force, replace path R1 and workpiece 9 after path R2 is mobile can via with continuous path R3, the R4 of path R2, to turn back to path R1 compared with the state that has initially carried out the posture conversion.
Above-mentioned force application part 6 utilizes system as shown in Figure 6 to move.
As mentioned above, air squit hole 64 is formed at one-sided in two faces of inwall of the 1st transport path 31.This air squit hole 64 is located at the position corresponding with the top of workpiece 9, from this position ejection air the time, Yi Bian on one side can apply rotational force to workpiece 9 efficiently workpiece 9 is moved to middle transport path 32.In addition, be set as shown in the figure so that at workpiece 9 in the situation of benchmark posture, namely in the situation of jagged 9a of the face of upside, this notch part 9a is positioned at identical position with air squit hole 64.
Force application part 6 constitutes, and can will supply with and ejection to this air squit hole 64 from the air that air tubing connection portion 61 imports via air via 63.
And this air squit hole 64 opens into the outside of transport platform 2 as through hole.And, at light projection unit 62a and the light receiver 62b that can be provided with via the position that this air squit hole 64 carries out the projection of light and reception as the opto-electronic pickup of above-mentioned workpiece posture detection parts 62.Signal from workpiece posture detection parts (opto-electronic pickup) 62 outputs to workpiece posture judging part 71, can judge whether position and this workpiece 9 that whether workpiece 9 has arrived air squit hole 64 are the benchmark posture.Then, the position and the workpiece posture that have arrived air squit hole 64 at workpiece 9 are not in the situation of benchmark posture, export to air supply section 72 in the mode of impulse singla to make workpiece 9 carry out the posture conversion order of posture conversion.
Air supply section 72 consists of with electromagnetic valve, and it can be received the pressurized air supplied with and this pressurized air is supplied to air tubing connection portion 61 or stop to supply with pressurized airs to air tubing connection portion 61 via the air pipe arrangement by not shown outside.And, input have from workpiece posture judging part 71, during as the impulse singla of above-mentioned posture conversion order, air supply section 72 can be in short time supplies with and gushes out from the pressurized air in air supply source to air squit hole 64.
Utilize said structure, use one group of opto-electronic pickup 62 owing to only depend on, not only can grasp the posture of workpiece 9, can also grasp simultaneously the position relationship of workpiece 9 and air squit hole 64, therefore can spray with the air that is used in the posture conversion of carrying out workpiece 9 good opportunity accordingly with the position of workpiece 9, can further improve the success ratio of posture conversion.
At this, in the mode corresponding with the action of the workpiece 9 that between above-mentioned each transport path, moves, explain the position relationship of above-mentioned each transport path with Fig. 7～Fig. 9.
(a) of Fig. 7 be illustrated on the 1st transport path 31 mobile workpiece 9 with notch part 9a the situation during towards position by air squit hole 64 of the benchmark posture of upside, it shows the cutaway view of this position.Be formed with the part of path R2 in the position corresponding with this air squit hole 64, this path R2 is the top side at the position throughput direction parallel, middle transport path 32 adjacent with the 1st transport path 31.
The 1st transport path 31 forms the cross section and is roughly V font and opening direction and tilts towards the upper right side a little from direction up from figure.By setting like this, can utilize two inboard walls to come two faces in 4 sides of holding workpieces 9.
Equally, middle transport path 32(R2) cross section also forms roughly V font, and it is set to and the 1st transport path 31 left-right symmetric roughly.That is opening direction,, middle transport path 32(R2 different from the opening direction of the 1st transport path 31) forms from direction up to tilt towards the upper left side a little.In other words, can say this opening direction with respect to the opening direction of the 1st transport path 31 to the 1st transport path 31 lopsidedness.
In addition, to the 1st transport path 31 and middle transport path 32(R2) position relationship set, so that at the 1st transport path 31 and middle transport path 32(R2) on loaded respectively under the state of workpiece 9, the part of workpiece 9 toward each other outstanding forming is overlapping state.By above-mentioned setting, can make workpiece 9 between transport path, move generation on one side on one side and rotatablely move and carry out the posture conversion.
But, because the workpiece 9 shown in Fig. 7 (a) is in the benchmark posture, thereby do not utilize the air ejection to carry out the posture conversion.
Relative therewith, shown in Fig. 7 (b), the workpiece 9 in the position that has arrived air squit hole 64 is not in the situation of benchmark posture, the light that the long-time shading light projection unit 62a of meeting sends to light receiver 62b.Thus, from above-mentioned workpiece posture judging part 71(with reference to Fig. 6) output posture conversion order, air is from 64 ejections of air squit hole correspondingly, workpiece 9 is on one side towards middle transport path 32(R2) mobile carry out on one side for change towards rotatablely move, thereby become the state shown in (c) of Fig. 8.
Afterwards, workpiece 9 is advanced to throughput direction, from middle transport path 32(R2) towards above-mentioned end side and become the state of the Fig. 8 that moves to the 2nd transport path 33 (d) via path R3, in the R3 of this path, be attended by until become reversing of the opening direction identical with the 1st transport path 31.In addition, because from throughput direction, at middle transport path 32(R2) and the workpiece 9 carried of the 2nd transport path and between the workpiece 9 that the 1st adjacent transport path 31 is carried, have overlapping part, therefore can in the situation of the position relationship on the throughput direction, carry with the state that arranges with the workpiece 9 of front and back.
Since the 2nd transport path 33 form the opening direction identical with the 1st transport path 31 towards, thereby, the workpiece 9 on the 2nd transport path 33 can have with initially be positioned at the 1st transport path 31 on the identical degree of dip of workpiece 9.
Then, workpiece 9 is by the corresponding position of and then arrival up at throughput direction and above-mentioned fluidic junction 34.In this fluidic junction 34, shown in Fig. 9 (e), the wall of close the 2nd transport path 33 1 sides in the inwall of the 1st transport path 31 is gradually near the 2nd transport path 33, final shown in Fig. 9 (f), the difference of the 1st transport path 31 and the 2nd transport path 33 disappears and becomes 1 the 1st transport path 31.
By above-mentioned setting, move to workpiece 9 on the 2nd transport path 33 carrying out 90 ° posture conversion around the axis parallel with throughput direction (X-axis) after from the 1st transport path 31, can turn back to the 1st transport path 31.
At this, among Figure 10 enlargedly expression utilize that air ejection makes that workpiece 9 moves from workpiece the 1st transport path 31 near the cross section of groove.
As mentioned above, the path R2 section of the 1st transport path 31 and middle transport path 32 forms and clips border between the two and consist of roughly symmetrical angle.And, form the formed angle α of wall of boundary portion between the two greater than 90 °, particularly, this angle α is set in 120 °～140 ° the scope.By above-mentioned setting, can reduce the rotation amount workpiece 9 rotates to middle transport path 32 from the 1st transport path 31 till, can utilize less application force easily to carry out the movement of workpiece 9.
And, because both boundary portion P are set as the R(rounding) shape, be rotated and move while can make contact point as T1～T5, change continuously mode that ground makes workpiece 9 move to slide along this R shape, thereby can make workpiece 9 be accompanied by the posture conversion and the less workpiece 9 that makes of gravity motion on above-below direction moves more smoothly.In addition, if be used for arranging the part of this R shape be positioned at make force application part 6(that workpiece 9 moves with reference to Fig. 4), more specifically air squit hole 64(is with reference to Fig. 4) neighbouring.
In addition, by will be from air squit hole 64(with reference to Fig. 4) pressure of the air of ejection, be that application force that force application part 6 produces is set for and made the workpiece 9 can be along the power of above-mentioned R shape upset, thus can prevent the spring of workpiece 9 or the posture conversion mistake of rolling and too much causing.
In Figure 11 (a), Figure 11 (b), as a comparative example, show the cross sectional shape as the groove of transport path that in the past used.Shown in Figure 11 (a), Figure 11 (b), the cross section is that the workpiece 9 of square form utilizes the primary air ejection to turn on one's side, towards by 90 ° of linear transformations.
Equally, in the situation of Figure 11 (a), be provided with concurrently the 2nd transport path 832 with the 1st transport path 831 as main transport path, the angle beta that forms the wall on above-mentioned border is set as 90 °.Therefore, the workpiece 9 that has been applied in rotational force because of the air of ejection centered by the P1 of border, on one side half-twist cross this outland on one side and move to the 2nd transport path 832 from the 1st transport path 831.
So, owing to need to be used for rotatablely moving and being used for crossing moving up and down of border of posture conversion, thereby, need to make the miles of relative movement of workpiece 9 elongated and make the gravity motion of workpiece 9 on above-below direction become large.Thereby, need to apply larger energy in order to make workpiece 9 do action, and require larger air spray volume, this causes energy consumption to become large.In addition, owing to forming sharp edge shape, boundary portion P1 make the sliding resistance between boundary portion P1 and the workpiece 9 larger, and then, because a small amount of scuffing of transport path, the individual differences such as roughness of surface of workpiece 9 can cause the motion of workpiece 9 to produce larger difference, easy generation posture conversion mistake.And owing to needing larger air spray volume to be difficult to the air spray volume is carried out trickle adjustment, this causes more being difficult to control the motion of workpiece 9 with the interaction of above-mentioned Individual differences.
In addition, shown in Figure 11 (b), sometimes also as only depending on, fulcrum rotatablely moves to carry out the movement of workpiece 9 take the boundary portion P2 between the 1st transport path 931 and the 2nd transport path 932.Even in this case, be accompanied by to form the rotary moving centered by the boundary portion P2 of sharp edge, it is large that the gravity motion of workpiece 9 on above-below direction also can become.Therefore, can make the required air ejection quantitative change of the movement of workpiece 9 large, consumption of energy is larger, and can not carry out the trickle adjustment of air and produce easily posture conversion mistake.In addition, owing to need to reduce the height of the wall of the 1st transport path 931 and a side the 2nd transport path 932, that be used to form boundary portion, thereby the stability of workpiece 9 reduces, and a small amount of disturb to wait can cause workpiece 9 to move by expecting.
Compare with the situation of above-mentioned Figure 11 that illustrates as a comparative example like that (a), Figure 11 (b), in the present embodiment, as shown in figure 10, required in movement by making, the gravity motion of workpiece 9 on above-below direction is less, thus can utilize less energy that workpiece 9 is moved.In addition, carry out the posture conversion on one side can make this R shape of workpiece 9 one edges carry out sliding motion owing to boundary portion P is made as the R shape, the scraping that therefore can not produce boundary portion P and workpiece 9 can make workpiece 9 stably mobile.In addition, because the inwall of each transport path constitutes and can have sufficient width (height of wall) with respect to workpiece 9, therefore can make the motion stabilization of the workpiece 9 in the course of conveying.
As mentioned above, arrange in the feedway 1 at the workpiece of the present embodiment that consists of as shown in Figure 1, while make in the following manner workpiece 9 arrange conveying workpieces 9.
Transport platform 2 is applied in the vibration that the lower left from figure is gone to the upper right side by utilization as the electromagnet 75 that vibration applies parts, thereby applies carrying capacity and workpiece 9 is moved to the workpiece 9 that is positioned on the transport platform 2 along the W direction among the figure.Be formed with as the cross section in transport platform 2 and be the roughly transport path 3 of the groove of V word shape, workpiece 9 moves along this transport path 3.
Workpiece 9 is by introduction part (A section) input in left side among the figure, while the long side direction that makes workpiece 9 towards throughput direction at transport path 3 internal support workpiece 9.Since workpiece 9 form roughly rectangular-shaped and only a mask in four faces of side feature is arranged, thereby, judge posture with this face towards the benchmark posture that is oriented of top.And, by in the 1st posture transformation component (B section) to the workpiece 9 ejection air with posture different from the benchmark posture applying application force, thereby workpiece 9 is moved by the path R2 of the 1st transport path 31 to middle transport path 32.Then, workpiece 9 one edge throughput directions are advanced on one side and to be moved and turn back to the 1st transport path 31 by fluidic junction 34 to the 2nd transport path 33 via path R3.At this moment, compare with initial state, workpiece 9 becomes the state behind the axis half-twist parallel with throughput direction.
The 2nd posture transformation component (C section) shown in Figure 1, the 3rd posture transformation component (D section) constitute identical with above-mentioned the 1st posture transformation component (B section), can make about 270 ° of workpiece 9 maximum rotations by the 1st posture transformation component (B section), the 2nd posture transformation component (C section), the 3rd posture transformation component (D section) by making workpiece 9.By above-mentioned setting, in the workpiece 9 that rectangular-shaped form is shown, no matter initial which side is positioned at the top, finally workpiece 9 can both be transformed to the benchmark posture.
After carrying out posture conversion as described above, utilize the 1st, the 2nd inspection section (E, F section) will exist the workpiece 9 of posture conversion mistake to be discharged to outside the manufacturing line, then, can pass through leading-out portion (G section) workpiece 9 is exported towards next operation.
As mentioned above, the workpiece of present embodiment is arranged feedway 1 makes the workpiece 9 that is positioned on the above-mentioned transport platform 2 move along above-mentioned transport path 3 by apply vibration to the transport platform 2 that is formed with transport path 3 on one side, make above-mentioned workpiece 9 become predetermined posture around the axis rotation parallel with throughput direction by the force application part 6 that has utilized air on one side, wherein, above-mentioned transport path 3 comprises: the 1st transport path 31, its cross section form the roughly groove of V font; Middle transport path 32, it is parallel and form the cross section and be the groove of V font roughly in the position adjacent with the 1st transport path 31, and, the opening direction at the top of this groove rolls tiltedly to above-mentioned the 1st transport path 31, and the opening direction of the terminal of this groove constitutes with the opening direction of above-mentioned the 1st transport path 31 roughly the same; The 2nd transport path 33, it forms on throughput direction with the continuous cross section of this centre transport path 32 and is the groove of V font roughly, and, the opening direction of this groove constitutes with the opening direction of above-mentioned the 1st transport path 31 roughly the same, and, in above-mentioned transport path 3, be formed with make above-mentioned the 1st transport path 31 and above-mentioned the 2nd transport path 33 on throughput direction gradually near and the fluidic junction 34 converged, make and utilize above-mentioned force application part 6 to be moved on one side around the postrotational workpiece 9 of the axis parallel with throughput direction transport path 32 in the middle of above-mentioned by above-mentioned the 1st transport path 31 transport path 32 in the middle of above-mentioned on one side to move while being further rotated to above-mentioned the 2nd transport path 33, and turn back to above-mentioned the 1st transport path 31 via above-mentioned fluidic junction 34.
Because as above-mentioned formation can reduce the rotation amount of the workpiece 9 that produced by the force application part 6 that uses air, therefore can utilize less air spray volume to make simply workpiece 9 rotations and alter one's posture.Therefore, energy consumption can be suppressed, and the posture conversion mistake such as excessive rotation, bounce-back of workpiece 9 can be suppressed.
In addition, owing to will be set as the R shape near at least force application part 6 in the boundary portion of above-mentioned the 1st transport path 31 and above-mentioned middle transport path 32, therefore can reduce workpiece 9 to be accompanied by rotation and gravity motion on above-below direction, thereby make workpiece 9 easier rotations, can improve above-mentioned effect.
And, when above-mentioned workpiece 9 will move from above-mentioned the 1st transport path 31 to above-mentioned middle conveying 32, owing to move the application force that the mode that is rotated has been set above-mentioned force application part on one side so that above-mentioned workpiece 9 one edges are formed at the R shape of above-mentioned boundary portion 34, therefore can make workpiece 9 more mobile.
In addition, because above-mentioned force application part 6 comprises: air squit hole 64, it is located at the 1st transport path 31; Air supply section 72, it is used for to these air squit hole 64 air supplies; Workpiece posture detection parts 62, it is for detection of the posture of above-mentioned workpiece 9; Workpiece posture judging part 71, it is according to judging from the signal of these workpiece posture detection parts 62 whether the posture of above-mentioned workpiece 9 is the posture of being scheduled to, above-mentioned force application part 6 makes air supply to above-mentioned air squit hole 64 from above-mentioned air supply section 72 according to the signal from this workpiece posture judging part 71, and make air by 64 ejections of above-mentioned air squit hole, therefore can automatically detect the posture of workpiece 9 and workpiece is transformed to the posture of benchmark.
And, because above-mentioned workpiece posture detection parts 62 are for having the opto-electronic pickup of light projection unit 62a and light receiver 62b, and so that passing above-mentioned air squit hole 64 and arrive the such position relationship of above-mentioned light receiver 62b, the light that is sent by above-mentioned smooth projection unit 62a is provided with above-mentioned smooth projection unit 62a and above-mentioned light receiver 62b, therefore can be by judge the posture of workpiece 9 from the signal of workpiece posture detection parts 62, and, owing to also can grasp exactly workpiece 9 with respect to the position of air squit hole 64, therefore air can be sprayed accurately, thereby posture conversion mistake can be suppressed further.
In addition, owing to be provided with above-mentioned middle transport path 32, above-mentioned the 2nd transport path 33, above-mentioned fluidic junction 34, above-mentioned force application part 6 and above-mentioned workpiece posture detection parts 62 in many places along throughput direction, thereby, can be by making workpiece 9 multiple rotary predetermined angulars carry out the posture conversion of polygonal workpiece 9 and workpiece 9 being arranged in specific direction.
The＜the 2 embodiment 〉
Figure 12 is the fluidic junction J1(34 that represents the workpiece arrangement feedway 1 of the 1st embodiment) near block diagram, Figure 13 is the fluidic junction J2(134 that the workpiece of expression the 2nd embodiment of the present invention is arranged feedway 101) near block diagram.
The workpiece of the 2nd embodiment is arranged feedway 101 only at fluidic junction J1(J2) form on to arrange feedway 1 different from the workpiece of the 1st embodiment, it is identical that part in addition and the workpiece of the 1st embodiment are arranged feedway 1.Therefore, for the position identical with the 1st embodiment, use identical symbol, omit the explanation for the part beyond the fluidic junction J2.In addition, such as Figure 12 and shown in Figure 13, be different with the fluidic junction J1 of the 1st embodiment from the length setting of the throughput direction of the fluidic junction J2 of the 2nd embodiment, still, this is not the intention point of the present application, both can be set as identical length yet.
To arrange at the workpiece of explanation the 2nd embodiment before the form of fluidic junction J2 of feedway 101, in order comparing therewith, to illustrate again that with Figure 12 the workpiece of the 1st embodiment arranges the fluidic junction J1 of feedway 1 first.
In Figure 12, shown in the arrow among the figure, take the upper right side of scheming as the throughput direction upstream side and utilize towards lower-left side conveying workpieces 9 towards describing.
In addition, in the figure, in order to make explanation simple, will from the throughput direction upstream side carry and the workpiece 191a that comes be oriented benchmark, suppose to have carried out the posture conversion and shown this workpiece 9 with the identical workpiece 9 that comes towards conveying, thereby the posture converted quantity of each several part is understood easily.Therefore, in the drawings, the posture of having passed through each workpiece 9 of fluidic junction J1 is messy state on the contrary, but, because the posture of workpiece 9 is carried out the posture conversion on one side on one side when the use of reality, thereby in principle, the posture of having passed through each workpiece 9 of fluidic junction J1 is compared upstream side becomes the state that approaches.This point is identical with Figure 13 described later.
For Figure 12, when illustrating successively towards the downstream from the throughput direction upstream side, in the drawings in the zone of upper right side, adjacent and be formed with concurrently as the path R 1 of the 1st transport path 31 and path R4 as the 2nd transport path 33.
In addition, the 1st transport path 31 and the 2nd transport path 33 form each cross section and are the groove of V font roughly, when two faces in the outside among the conveyor surface that will be made of on the whole above-mentioned the 1st transport path 31 and the 2nd transport path 33 are set as face K1, L1, at the position that these faces K1, L1 intersect, Yi Bian can agree that the rectangular teat S1 one edge throughput direction in picture cross section extends integrally formation.
The 1st transport path 31(R1 like this) with the 2nd transport path 33(R4) at the fluidic junction J1(34 of conveyance direction downstream side) locate gradually near and converge.Specifically describe this situation, above-mentioned teat S1 by the 1st transport path 31(R1) the face S11 of side is along with coming conveyance direction downstream side, can ramped shaped ground to the 2nd transport path 33(R4) the face L1 of side is close, final teat S1 disappears, and face K1 and face L1 are directly crossing and make the roughly groove of V word shape of Formation cross-section.
That is, from throughput direction, because teat S 1 disappears the 1st transport path 31(R1) and the 2nd transport path 33(R4) converge, again consisted of the 1st a transport path 31(R1).
Workpiece 9 can carry out following movement by after such fluidic junction J1.For example, do not move but be transferred the workpiece 91a that comes at the 1st transport path 31 and can under keeping the constant situation of posture, as the workpiece 91b among the figure, advance to the 2nd transport path 33.And workpiece 91a can be in the situation that keeps its posture, and the slope that the teat S1 among the edge fluidic junction J1 forms is mobile a little to the 2nd transport path 33 sides, Yi Bian the 1st transport path 31 of side is advanced downstream.On the other hand, on one side move the workpiece 92a that carries out the posture conversion on one side from the 1st transport path 31 to the 2nd transport path 33 and can under keeping the constant situation of posture, as the workpiece 92b the figure, advance.And, owing to disappear along throughput direction teat S1 in the traveling process at fluidic junction J1 place, thereby the position of workpiece 92b can correspondingly vary near the 1st transport path 31, thus workpiece 92c as shown in FIG. is mobile like that.
Like this, because respectively at the 1st transport path 31(R1) with the 2nd transport path 33(R4) posture not variation at fluidic junction J1 place of the up and then workpiece 9 that comes, thereby, respectively by the 1st transport path 31(R1) with the 2nd transport path 33(R4) workpiece 9 can relatively carry out 90 ° posture conversion.
Then, illustrate that with Figure 13 the workpiece of the 2nd embodiment arranges the structure of the fluidic junction J2 of feedway 101.Identical with Figure 12, in Figure 13, also shown in the arrow among the figure, take the upper right side of scheming as the throughput direction upstream side and utilize towards lower-left side conveying workpieces 9 towards describing.
Equally, in this case, in the drawings in the zone of upper right side, adjacent and be formed with concurrently as the path R 1 of the 1st transport path 31 and path R4 as the 2nd transport path 33.
When two faces in the outside among the conveyor surface that will be made of on the whole the 1st such transport path 31 and the 2nd transport path 33 are set as face K2, L2, at the position that these faces K2, L2 intersect, Yi Bian can agree to form an edge throughput direction as the rectangular teat S2 in cross section to extend the shape of having carried out integrated.
The 1st transport path 31(R1 like this) with the 2nd transport path 33(R4) before conveyance direction downstream side and then respectively, be connected smoothly with path R22 with path R21.With the 1st transport path 31(R1) with the 2nd transport path 33(R4) identical, this path R21, R22 form the roughly groove of V font of cross section, make face K2, L2 respectively with the 1st transport path 31(R1) with the 2nd transport path 33(R4) continuously, but, along with advancing at throughput direction, the direction that this path R21, R22 formation opening direction separates is respectively towards each other reversed the shape that forms.
Thus, the angle that face K2 and face L2 consist of is about 90 ° at the throughput direction upstream side, and is relative therewith, and at the path in downstream R21, R22 place, face K2 becomes the obtuse angle with the dihedral that face L2 consists of and is set to about 110 °～140 ° larger like that apertures.Accompany therewith, along with advancing to conveyance direction downstream side, the angle of the apex portion of teat S 2 is gradually changed to the less acute angle of angle by about 90 ° state.
And, this path R21, R22 each other gradually near and become as path R23, a cross section is the roughly convergence slot 135 of V word shape.Specifically describe this convergence slot 135, along with advancing to conveyance direction downstream side, above-mentioned teat S2 diminishes equally by the face S21 of path R21 side with by the face S22 of path R22 side, final teat S2 disappears, and face K2 and face L2 are directly crossing and Formation cross-section is the roughly convergence slot 135(path R23 of V word shape).At this moment, owing to be applied with above-mentioned reversing, thereby angle of release can open into about 110 °～140 ° sizes significantly.
And the convergence slot 135 that is used for formation path R23 is connected smoothly with the path R24 that forms the position adjustment tank 136 with circular-arc cross section.Thus, in this zone, face K2 and face L2 are a curved surface smoothly continuously.
And, again continuous smoothly with the 1st transport path 31 in downstream via path R25 for the terminal of the position adjustment tank 136 that consists of path R24.
As mentioned above, in path R21～path R25, the 1st transport path 31, the 2nd transport path 33 converge, and then path R21～path R25 consists of the fluidic junction J2 that is connected with the 1st transport path 31 in downstream.
Workpiece 9 can carry out following movement by such fluidic junction J2.For example, not do not move to the 2nd transport path 33 but can be along the reversing of path R21 by the workpiece 191a that transports at the 1st transport path 31, as workpiece 191b, carry while carry out rotating a little from the anti-clockwise that throughput direction is seen.Then, when workpiece has arrived the convergence slot 135 that consists of path R23, from throughput direction, the posture anticlockwise direction conversion of workpiece about 30 °.
The workpiece 191c that has arrived convergence slot 135 becomes the mutually state of scraping of intersection point part that its marginal portion that forms and face K2, L2 consist of between the side, move while workpiece 191c is subject to the restriction of this part.Particularly, although side and the face K2 of workpiece 191c connect, but, workpiece 191c is basic owing to the scraping of marginal portion not to be had to connect with adjacent face L2 side, thereby workpiece 191c carries to the position adjustment tank 136 that consists of next path 24 under the state that is only supported by face K2 side.
At these position adjustment tank 136 places, become a level and smooth curved surface owing to face K2 is connected with face L2, thereby above-mentioned intersection point part does not exist, the restriction of this intersection point part edge part is disengaged, Yi Bian on one side workpiece 191c automatically is adjusted to stable position moves.At this moment, from throughput direction, Yi Bian workpiece 191c further anticlockwise direction rotation on one side is positioned at the bottom of position adjustment tank 136.Then, this workpiece 191c is via path R25, on one side with the mode that again forms initial degree of dip be limited towards, move to the position of the workpiece 191d in the 1st transport path 31 in downstream on one side.
On the other hand, the workpiece 192a that moves to the 2nd transport path 33 from the 1st transport path 31 reverses along path R22's, while carry out carrying from the clockwise a little rotation that throughput direction is seen.Then, when workpiece has arrived path R23, from throughput direction, the posture clockwise direction conversion of workpiece about 30 °.
