In Fig. 3 and Fig. 4, pedestal 1 in the face of a side of transport platform 3 is formed with ring-type negative pressure trough 11, and link to each other with not shown vacuum generation source.And, being communicated to the spot-facing 12 of ring-type negative pressure trough 11 and attracting hole 13 of transport platform 3, can and remain in the workpiece reception hole 4 workpiece W vacuum suction in the face of a side of pedestal 1 is provided with from workpiece reception hole 4.And, on pedestal 1, with relative with the inlet 8a of upset passage to the corresponding position of workpiece reception hole 4a, be provided with fumarole (pressure gas ejection mechanism) 14a towards the inlet 8a of upset passage, this fumarole 14a links to each other with air supply source 14c.In addition, on pedestal 1, with the upset passage outlet 8b relative to workpiece reception hole 4b why corresponding, towards the upset passage outlet 8b be provided with fumarole (pressure gas gigback) 14b, this fumarole 14b links to each other with air supply source 14c.At this, workpiece reception hole 4a, 4b all represent same workpiece reception hole, when the workpiece reception hole come relative with the 8a that enters the mouth to the position time become workpiece reception hole 4a, come with export 8b relative to the position time become workpiece reception hole 4b.In addition, above-mentioned each component parts carries out drive controlling by control part 30a.
Below, the effect of the present embodiment of this structure is described.At first, the workpiece W that is accommodated in the workpiece reception hole 4,4a, 4b of transport platform 3 is transferred along with the rotation of transport platform 3, judges the polarity of workpiece W in polarity judging portion 6.
Then, transport platform 3 is rotated, and is judged to be opposite polarity workpiece W1 with near the inlet 8a that is accommodated in the state arrival upset passage among the workpiece reception hole 4a by polarity judging portion 6, and transport platform 3 stops.Then, the workpiece W1 in the workpiece reception hole 4a is admitted to upset passage 8, by 8 upsets of upset passage, and be accommodated in export 8b relative to workpiece reception hole 4b in.
That is, be accommodated in workpiece W among the workpiece reception hole 4a of transport platform 3 by polarity judging portion decision polarity.At this moment, in the time of near being judged as the inlet 8a that opposite polarity workpiece W1 arrives the upset passage, transport platform 3 stops, based on the result of determination of polarity judging portion 6, instruction by control part 30a sprays air (arrow P Fig. 4) from fumarole 14a, and workpiece W1 is admitted to upset passage 8.On the other hand,,, can not spray air from fumarole 14a even arrived near the inlet 8a of upset passage for the correct workpiece of polarity yet, but intactly to carry with the state that is accommodated among the workpiece reception hole 4a.
Fig. 7 (a) has represented that opposite polarity workpiece W1 just has been admitted to the appearance of upset passage 8.Jet when by from fumarole 14a, when workpiece W1 was admitted to upset passage 8, entrance side sensor S1 detected the inlet 8a that workpiece W1 has passed through upset passage 8.
Therebetween, source 32 takes place with vacuum and links to each other in gas storage portion 15, carries out vacuum attraction (the arrow J Fig. 7 (a)) from outlet 8b one side of upset passage 8 towards inlet 8a one side.The air-flow of this moment comprise from the inlet 8a of upset passage 8 flow into air drain 16a, 16b, 16c, 16d air-flow and by vacuum attraction from the atmosphere opening hole 19 these two kinds of air-flows of air-flow that flow into air drain 16a, 16b, 16c, 16d.At this, for the workpiece W1 that sends into upset passage 8 is stopped in upset passage 8 reliably, make the sectional area of the sectional area of the aperture area in atmosphere opening hole 19 and atmosphere opening groove 20, thereby make in above-mentioned two kinds of air-flows from the air-flow in atmosphere opening hole 19 greater than air-flow from the inlet 8a of upset passage 8 greater than upset passage 8.
In addition, in Fig. 7 (a), since workpiece be accommodated in outlet 8b with the passage 8 that overturns relative to workpiece reception hole 4b in, so the air-flow in the upset passage 8 is above-mentioned two kinds of air-flows, but under workpiece is not accommodated in situation among the workpiece reception hole 4b, by acting on the vacuum attraction in the attraction hole 13 in the workpiece reception hole 4b, also produce from atmosphere opening hole 19 towards the air-flow of workpiece reception hole 4b.Under any situation, the air-flow in the upset passage 8 is all by 19 disjunctions of atmosphere opening hole.As mentioned above, by by the air-flow of atmosphere opening hole 19 disjunctions, the workpiece W1 in the upset passage 8 can not arrive outlet 8b ground and slow down, and stop at position that the air drain 16a of upstream side links to each other with the passage 8 that overturns and a certain position between the atmosphere opening hole 19.This state is shown among Fig. 7 (b).
Stop at the moment of upset in the passage 8 at workpiece W1, stopped jet from fumarole 14a, source 32 takes place with vacuum and links to each other in gas storage portion 15, carries out vacuum attraction (the arrow J Fig. 1 (a)) from outlet 8b one side of the passage that overturns towards 8a one side that enters the mouth.
Therebetween, on the polarity judging portion 6 that is provided with along the rotate path of transport platform 3, upset portion 7 and not shown test section and classification discharge portion etc., the operation that in the stopping of transport platform 3, puts rules into practice respectively.After the execution that wherein needs most the operation of time finished, transport platform 3 began rotation (the arrow L among Fig. 7 (a)) once more.And, the workpiece reception hole 4a that has taken in workpiece W1 towards with the outlet 8b of upset passage relative to the position move.
Then, the workpiece reception hole 4a that has taken in workpiece W1 is the amount of a spacing of travelling workpiece reception hole only, arrive outlet 8b with the passage that overturns relative to the position and become workpiece reception hole 4b, transport platform 3 stops (Fig. 7 (c)).At this moment, the danger signal that expression transport platform 3 has stopped sending to control part 30a, by instruction from control part 30a, and transfer valve 31 actions, gas storage portion 15 links to each other with air supply source 33.And, by four air drain 16a, 16b, 16c, 16d, carrying out jet (the arrow K Fig. 7 (c)) towards outlet 8b one side from inlet 8a one side of upset passage 8, the air of ejection discharges from atmosphere opening hole 19.So, the workpiece W1 that stops in the passage 8 in upset moves and arrives the position in atmosphere opening hole 19 towards the outlet 8b of upset passage 8.Though air 19 discharges from the atmosphere opening hole from air drain 16a, 16b, 16c, 16d ejection, but because the air of a part is towards the outlet 8b of upset passage 8, thus the position of workpiece W1 by atmosphere opening hole 19 arrive outlet 8b with the passage 8 that overturns relative to workpiece reception hole 4b.And the state with polarity upset is accommodated among the workpiece reception hole 4b workpiece W1 by the vacuum attraction in the attraction hole 13 in the workpiece reception hole 4b.When outlet side sensor 32 detected workpiece W1 and passed through the outlet of workpiece reception hole 4b, transport platform 3 can be rotated once more, and transport platform 3 begins rotation once more.At this moment, by instruction from control part 30a, transfer valve 31 actions, source 32 takes place with vacuum and links to each other in gas storage portion 15, carries out vacuum attraction from outlet 8b one side of upset passage 8 towards inlet 8a one side, and next workpiece W is admitted to upset passage 8.
In addition, under workpiece W1 correctly is not accommodated in situation among the workpiece reception hole 4b, detects workpiece W1 by outlet side sensor S2 and correctly be not accommodated in the workpiece reception hole 4b.In this case, from being arranged on the pedestal 1 and the corresponding locational fumarole 14b air-out of workpiece reception hole 4b, workpiece W1 is temporarily returned in the upset passage 8.Then, outlet 8b one side jet by towards upset passage 8 is accommodated in workpiece W1 among the workpiece reception hole 4b once more.
According to present embodiment, after transport platform 3 is stopped, and by polarity judging portion 6 be judged to be opposite polarity workpiece W1 in workpiece reception hole 4a passes out to upset passage 8 after, can make this workpiece W1 deceleration and stopping in upset passage 8.Make thereafter transport platform 3 only a spacing of turning of work piece reception hole amount and stop.Then can the workpiece W1 in the upset passage 8 be returned to the workpiece reception hole 4b of transport platform 3 by pressurized air.Therefore, owing to can make the mobile moment of transport platform 3 consistent to the moment that the workpiece reception hole 4b of transport platform 3 returns with workpiece W1, so workpiece W1 can not conflict with transport platform 3 and injure workpiece W1 or transport platform 3.
In the above-described embodiment, the workpiece W1 that passes out in the upset passage 8 is stopped in upset passage 8, and stop to the workpiece reception hole 4b that should take in this workpiece W1 arrive outlet 8b with the passage 8 that overturns relative to the position, workpiece reception hole 4b arrived with the upset passage 8 outlet 8b relative to the position after, to this workpiece W1 quicken and be directed to the outlet 8b, but the rotative speed in transport platform 3 is big, the workpiece reception hole 4b that should take in this workpiece W1 arrive outlet 8b with upset passage 8 relative to time of position situation of lacking under, also can make this workpiece W1 decelerate to the speed that is unlikely to stop, workpiece reception hole 4b arrived relative with outlet 8b to the position after be directed to outlet 8b in that this workpiece W1 is slowed down.
And, though four air drain 16a, 16b, 16c, 16d are illustrated with the example that upset passage 8 links to each other, but since be reliable and the passage 8 that promptly overturns in the stopping and moving again of workpiece W1, so according to the size of workpiece W1 and the rotative speed of weight or transport platform 3 etc., the quantity of air drain is not limited in four, can set suitable bar number for.
And, in the present embodiment, though same air drain 16a, 16b, 16c, 16d are illustrated by transfer valve 31 being switched the situation with vacuum attraction and jet function, but also can be that some air drain has the vacuum attraction function among air drain 16a, 16b, 16c, the 16d, and remaining air drain have jet function.
