Background technology
In the past, known a kind of workpiece classification discharger, that the absorption of workpieces of sheet shape electronic unit etc. is remained in the workpiece reception hole of the peripheral part that is arranged at convey table, carry out the mensuration of electrical characteristic simultaneously, according to the measurement result of workpiece, workpiece is divided into predefined multiple classification, via discharge pipe, workpiece is expelled in the containing box corresponding with each classification.In such device, if the number increase of containing box of number of categories increase.Therefore with containing box, discharge pipe is set respectively accordingly, the number of the workpiece reception hole of convey table need to, on the number of discharge pipe, cause the maximization of convey table.Now, cause maximization and the high priceization of device.
On the other hand, be known in the case of the number of containing box increases, reduce the number of the discharge pipe that workpiece is discharged from convey table, the device (for example patent documentation 1) that near position containing box connects discharge pipe branch respectively for containing box.
Such workpiece classification discharger 100 as shown in figure 31, has: index table 102, and carry intermittence as the sheet shape electronic unit (hereinafter referred to as workpiece) of checked property and measure; And distributor 103, configure adjacently with this index table 102, distribute the each workpiece W measuring after finishing according to measurement result.
In Figure 31, carry by the intermittent rotary of index table 102 the workpiece W being adsorbed by adsorption nozzle 108, and measured by determinator (not shown).Each workpiece W is assigned to respectively the multiple classification corresponding with measurement result, and is stored in the workpiece containing box 115A corresponding with each classification by distributor 103.
Distributor 103 as shown in figure 31, there are the multiple distribution member 114 corresponding with each workpiece containing box 115A difference, in each distribution member 114, upward and configuration side by side in the direction parallel with paper and the direction vertical with paper, the upper surface of distribution member 114 forms the dome shape recess 114B being formed by distribution openings 114A to distribution openings 114A.Be provided with an input pipe 112 for sending into workpiece W at release position B, the ball face sealing parts 123 of ring-type are installed at the peripheral part of its bottom 112B.And, swing in the direction parallel with paper and the direction vertical with paper centered by ball face sealing parts 123 with dropping into swing pipe 113 that pipe 112 bottom 112B connects by the effect of motor, make the bottom 113B of the swing pipe 113 approaching with dome shape recess 114B be positioned at the top position that approaches of each distribution openings 114A.
According to the measurement result of the each workpiece W from determinator, control device CD-ROM drive motor.Thus, make the bottom 113B of swing pipe 113 move to the top position that approaches of distribution openings 114A that each workpiece W should be assigned with.And, after workpiece W is carried to release position B by index table 102, remove the negative pressure of adsorption nozzle 108, spray Compressed Gas from nozzle 111, workpiece W is sent into and dropped in pipe 112.Now, after this workpiece W manages 112 by input, through swing pipe 113 and this distribution openings 114A, be stored in the workpiece containing box 115A corresponding with the classification of measurement result.
Patent documentation 1: TOHKEMY 2006-78347 communique
There is following problem points in such conventional art.
In Figure 31, in the time that workpiece W is expelled to workpiece containing box 115A, once workpiece W drops into after pipe 112 by one, be just fed to the distribution openings 114A corresponding with each workpiece containing box 115A.Therefore,, in order to prevent that the workpiece W receiving in different workpiece containing box 115A from sneaking into, need to manage at workpiece W 112 outlet by input after, then discharge next workpiece W.Now, from workpiece W be admitted to drop into that pipe 112 to workpiece W is sent become the stand-by period by the time, be difficult to the high speed of the processing speed of implement device.
Should pass through time shorten in order to realize high speed, and need to make the total length that drops into pipe 112 shorten, the configuration of device Nei Ge mechanism is restricted.And the time that makes the bottom 113B of swing pipe 113 move to the position of distribution openings 114A also becomes the stand-by period, is difficult to the high speed of the processing speed of implement device.In order to realize high speed, shorten this traveling time, need to make the mechanism of swing pipe 113 high-speed mobile in wide scope, cause the cost of device to rise.
And the occurrence frequency of the classification of workpiece W has certain tendency, therefore workpiece W is accommodated in each workpiece containing box 115A equably.Conventionally the occurrence frequency of specific several classification is high, the workpiece W receiving in the workpiece containing box 115A that classifies corresponding with these is many, the frequency gets higher that therefore the bottom 113B of swing pipe 113 moves towards the position of the distribution openings 114A being connected with this workpiece containing box 115A.Thus, for the high speed of the processing speed of implement device, need to make the distribution openings 114A of the distribution member 114 that the classification corresponding workpiece containing box 115A high with these occurrence frequencies be connected configure close to each otherly.But even in this case, the bottom 113B of swing pipe 113 mobile time between different distribution openings 114 can not be also zero, the high speed of the processing speed of device is limited.
For example, number of categories in the nearest workpiece of the workpiece such as light-emitting diode being classified and discharging classification discharger is 128,256 or 512 etc., become very large, if realize the workpiece classification discharger corresponding with these number of categories by technology in the past, the cost of device becomes very high, and the high speed of action becomes very difficult.
And because the corresponding workpiece containing box of the high classification of occurrence frequency as above 115A becomes full in early days, the power supply that produces shearing device stops device and uses empty new workpiece containing box to exchange the operation of the workpiece containing box 115A that becomes full.Now, distribution openings 114A is in open state, therefore exists in the swap operation foreign matter such as rubbish enter and sneak into the problem of workpiece containing box 115A from distribution openings 114A.
Operational example beyond swap operation, as also wanted the power supply of shearing device that device is stopped the maintenance test operation of device, therefore produces same situation.And, in the situation that device produces any fault and emergent stopping, also produce same situation.In order to prevent that the foreign matters such as rubbish from entering from distribution openings 114A like this, need to be in the time that device stops the mechanism of enclose distributor mouth 114A, cause the cost of device to improve.

If under this state, spray Compressed Gas from squit hole 10 to workpiece W,, as shown in Fig. 3 (b), workpiece W is admitted to and discharges in module 81.Fig. 3 (c) (d) (e) illustrate respectively discharge in 4 layers of basic 81A of stratum of module 81, the opposed situation of workpiece reception hole 3 of the basic II of stratum, III, IV and the convey table 2 shown in Fig. 5.At this, discharging module 81 declines with the order of Fig. 3 (a)-> Fig. 3 (c)-> Fig. 3 (d)-> Fig. 3 (e), accompany with it, the coil 86 being made up of retractile spring compresses, and prevents from flatly extending from the back side of the basic 81A of stratum and changing into towards the pipe 85 of about 90 belows of spending and be out of shape.And therefore coil 86 is formed and is had gap in periphery by spring.Thus, when the Compressed Gas spraying to workpiece W at the spray-hole 10 from Fig. 4 (a) arrives coil 86 from workpiece outlet 8x via pipe 85 along with workpiece W, this Compressed Gas can discharge to outside from the gap of coil 86, workpiece W fall to workpiece containing box 115 when interior not from transporting compressed gas body above workpiece W.Thus, workpiece W becomes the state that nature falls that approaches, and being newly accommodated in workpiece W in workpiece containing box 115 can compressed gas pushing and conflict and damage with the inwall of workpiece containing box 115 or the workpiece W that has been accommodated in workpiece containing box 115.And, do not have yet Compressed Gas with being accommodated in that workpiece W in workpiece containing box 115 meets problem that this workpiece W is kicked up again.
And, Fig. 3 (f) illustrate discharge module 81 entirety with than the also opposed and situation that stops of the outer peripheral face 1a of pedestal 1 on the lower of convey table 2.This state is for maintenance test etc. and when the power supply of shearing device, or produces any fault and state when emergency braking device at device.By being stopped by this position that acts on of control part 9, whole workpiece outlet 8x are sealed by the outer peripheral face 1a of pedestal 1, prevent that the foreign matters such as rubbish from entering workpiece containing box 115 from outlet 8x.
In addition, can be as shown in figure 30, will manage 85 and be connected with discharge module 81, and this pipe 85 will be configured in large diameter pipe 85A sliding freely.And large diameter pipe 85A is fixed on supporting station 87.
In Figure 30, along with discharging the lifting of module 81, pipe 85 can move along above-below direction in large diameter pipe 85A.Now, the external diameter of pipe 85 is slightly less than the internal diameter of large diameter pipe 85A.
Then, the following describes the effect of the present embodiment of such structure.
First, in Fig. 1, workpiece W is housed in rotation and is arranged on freely in workpiece reception hole 3 set on the peripheral part 2a of the convey table 2 on pedestal 1, and by the effect of not shown drive unit, convey table 2 is clockwise intermittent rotary (arrow A of Fig. 1) around central shaft 4.
And, when the workpiece W in workpiece reception hole 3 arrives workpiece determination part 7, measuring the electrical characteristic of workpiece W by this workpiece determination part 7, the workpiece W measuring after finishing arrives discharge portion 8a, 8b.Workpiece W, according to the measurement result that is sent to each workpiece W of control part 9 from workpiece determination part 7, is divided into predefined multiple classification by control part 9, and discharges to the workpiece containing box 115 corresponding with this classification.
Each discharge portion 8a, 8b are as shown in the front view of Fig. 5, and the discharge module 81 by comprising with these 4 basic 81A of stratum of I～IV of 8 the workpiece outlet 8x in (1)～(8) forms.
The discharge module 81 that forms discharge portion 8a, 8b moves freely in (arrow C of Fig. 2) in the vertical direction integratedly by driving mechanism 81a.And, by discharge module 81 to the movement of vertical direction, i.e. lifting, as Fig. 3 (a) (c) (d) (e) as shown in, the workpiece W in the workpiece reception hole 3 of convey table 2 can and the workpiece outlet 8x of the basic 81A of stratum of I～IV opposed respectively.
Thus, make to discharge module 81 and formed by the basic 81A of stratum of multiple stratum (these 4 layers of I～IV in Fig. 5), and lifting integratedly, make the workpiece W in workpiece outlet 8x and workpiece reception hole 3 freely opposed.Thus, even if it is large that predefined number of categories becomes, the number ((1)～(8) in Fig. 5) that also can not make to be formed on the workpiece outlet 8x on the basic 81A of stratum of a stratum increases, and can the number of workpiece outlet 8x be increased by stratum's number is increased.Thus, large even if number of categories becomes, do not need the number of the workpiece reception hole 3 that makes convey table 2 to increase yet, do not need to increase the diameter of convey table 2, therefore can make equipment miniaturization.And, discharge module 81 and only move along vertical direction, the therefore simple structure of drive unit 81a, the mobile needed time is also short.
Then, describe the classification discharging method of the workpiece W in discharge portion 8a, 8b in detail according to Fig. 6～Figure 28.Fig. 6～Figure 28 schematically shows the convey table 2 seen from the arrow T direction of Fig. 2 and the position relationship of discharge portion 8a, 8b.
Discharge portion 8a, 8b are respectively as shown in Figure 5, the discharge module 81 by comprising with these 4 layers of basic 81A of stratum of I～IV of 8 the workpiece outlet 8x in (1)～(8) forms, and workpiece W can be expelled in 32 workpiece containing boxs 115 suitable with the sum of workpiece outlet 8x., discharge portion 8a, 8b can be expelled to workpiece W in 64 workpiece containing boxs 115 altogether.
Like this, can, according to the measurement result of the workpiece W in the workpiece determination part 7 of Fig. 1, workpiece W be divided into predefined 64 classification.
At this, Fig. 6～Figure 28 and Fig. 5 illustrate the workpiece outlet 8x of each discharge portion 8a, 8b in the same manner with the form of horizontal 8, perpendicular 4, give the symbol of workpiece outlet 8x mark (1)～(8) of transverse direction, give the symbol of the basic 81A of the stratum mark I～IV of longitudinal direction.And, on the workpiece outlet 8x of each discharge portion 8a, 8b, illustrate as 1～64 of number of categories using continuous symbol.For example, the I of discharge portion 8a (3) is equivalent to classify 3, and the III (6) of discharge portion 8b is equivalent to classify 46.
At this, the discharge module 81 of discharge portion 8a, 8b all becomes the state of equal height, state that Fig. 3 (a) illustrates as initial condition taking the workpiece outlet 8x of the basic 81A of stratum of I and convey table 2.And, control driving mechanism 81a by control part 9, discharge module 81 liftings, move to (d) each state of (e) of Fig. 3 (c).And, in Fig. 6～Figure 28, be listed as with horizontal one the workpiece reception hole 3 that convey table 2 is shown in the same manner with above-mentioned workpiece outlet 8x, each workpiece reception hole 3, to be marked at the alphabetical small character identification of downside, is marked with the classifying and numbering (any of 1～64) of the discharge order that the workpiece W being accommodated in workpiece reception hole 3 is shown.
For easy, in Fig. 6～Figure 28, the number of workpiece reception hole 3 is defined as these 18 of a～r.When convey table 2 is during towards the arrow A direction intermittent rotary of Fig. 2, in Fig. 6～Figure 28, convey table 2 advances to the direction of arrow A.In Fig. 6, be accommodated in workpiece reception hole 3 (a, b, c, d ...) in the classifying and numbering of workpiece W be followed successively by 1,5,14,10 ...This means, the I (1) that the workpiece W of for example workpiece reception hole a is discharge portion 8a from workpiece outlet 1 discharges, and the I (5) that the workpiece W of workpiece reception hole b is discharge portion 8a from workpiece outlet 5 discharges.For convenient, for example, in Fig. 6, convey table 2 discharge portion 8a, 8b slightly below mark, but be in fact present in the plane identical with upper set workpiece outlet I (the 1)～I (8) (classifying and numbering 1～16) of the basic I of stratum of discharge portion 8a, 8b.In Fig. 7～Figure 28, the position relationship of convey table 2 and discharge portion 8a and 8b is also identical.
Below, key diagram 6～Figure 28 in order, but for easy, " workpiece reception hole " is designated as to " reception hole ", " workpiece outlet " is designated as to " outlet ".
When convey table 2 is during from the initial condition intermittent rotary of Fig. 6, become the state of Fig. 7.At this, the workpiece W of the reception hole a of convey table 2 is opposed with the outlet 1 that should be discharged from (I (1) of discharge portion 8a).
In Fig. 7, for clear and definite this point, stamp shade to reception hole a and outlet 1.In Fig. 8～Figure 28, while also giving with same case, corresponding reception hole and outlet stamped shade below.
Control part 9 is by the information sending from workpiece determination part 7, the outlet that confirmation should be discharged the workpiece W of reception hole a is 1, therefore, in Fig. 7, under reception hole a and the opposed state of outlet 1, workpiece W in the reception hole a of state that is in Fig. 4 (b), sprays Compressed Gas from the squit hole 10 of Fig. 4 (a) towards the direction of arrow C, and this workpiece W is sent into outlet 1.Now, be changed to the direction of the arrow D of Fig. 4 (a) from the direction of the arrow E of Fig. 4 (b) from the light of light source 11a, detect that workpiece W has been admitted to outlet 1 from reception hole a.
This testing result is sent to control part 9, if confirm there is no other workpiece W that should be discharged from stage control portion 9 as shown in Figure 7, control part 9 makes convey table 2 intermittent rotaries, moves to the state of Fig. 8.
In Fig. 8, reception hole b and outlet 1 are opposed.Now, control part 9 confirms that the workpiece W in reception hole b is discharged to outlet 5, even if make discharge module 81 liftings of discharge portion 8a under the state of Fig. 8, with the opposed outlet of reception hole b be also some in 17 (II (1)), 33 (III (1)), 48 (IV (1)), therefore control part 9 is at the state of Fig. 8 workpiece W that will do not discharged that judges, make convey table 2 intermittent rotaries, move to the state of Fig. 9.
In Fig. 9, about the workpiece W in reception hole b and reception hole c, control part 9 and the situation of Fig. 8 judge does not in the same manner have the workpiece W that will be discharged from, and makes convey table 2 intermittent rotaries, moves to the state of Figure 10.
In Figure 10 and Figure 11, be also in the same manner, control part 9 judges and there is no the workpiece W that will be discharged from the state of each figure, makes convey table 2 intermittent rotaries, moves to the state of Figure 12.At this, in Figure 12, the workpiece W of reception hole b is opposed with the outlet 5 that should be discharged from (I (5) of discharge portion 8a).Therefore the situation of control part 9 and Fig. 7 in the same manner, sprays Compressed Gas from squit hole 10, and this workpiece W is sent into outlet 5.And, detect that by light source 11a and photodetector 11b workpiece W is fed through outlet 5 from reception hole b, and this check result is sent to control part 9, under the stage as shown in figure 12, control part 9 is confirmed the workpiece W that does not have other to discharge, control part 9 makes convey table 2 intermittent rotaries, moves to the state of Figure 13.
In Figure 13～Figure 16, identical with Fig. 8, control part 9 judges and there is no the workpiece W that will be discharged from the state of each figure, makes convey table 2 intermittent rotaries, moves to the state of Figure 17.
In Figure 17, the outlet 20 (II (4) of discharge portion 8a) that should discharge the workpiece W in reception hole h declines by the discharge module 81 that makes discharge portion 8a and is opposed with reception hole h.Therefore, control part 9 is controlled driving mechanism 81a, and the discharge module 81 of discharge portion 8a is declined, and makes the basic 81A of stratum of II be positioned at the height identical with convey table 2.And, spray Compressed Gas from squit hole 10 in the same manner with the situation of Fig. 7, this workpiece W is sent into outlet 20.And light source 11a and photodetector 11b detect that workpiece W is admitted to outlet 20 from reception hole h, and this testing result is sent to control part 9.
Then,, under this state, the outlet 39 (III (7) of discharge portion 8a) that should discharge the workpiece W in reception hole e again declines by the discharge module 81 that makes discharge portion 8a and is opposed with reception hole e.Therefore, as shown in figure 18, control part 9 is controlled driving mechanism 81a, and the discharge module 81 of discharge portion 8a is declined, and makes the basic 81A of stratum of III be positioned at the height identical with convey table 2.And, spray Compressed Gas from squit hole 10 in the same manner with the situation of Fig. 7, this workpiece W is sent into outlet 39.And light source 11a and photodetector 11b detect that workpiece W is admitted to outlet 39 from reception hole e, and this testing result is sent to control part 9.
At this, in Figure 17 and Figure 18, under the state that convey table 2 is stopped, discharging continuously two workpiece W from reception hole h and reception hole e.
Under these circumstances, in the prior art, in Figure 30, when workpiece W is expelled to different workpiece containing boxs 115 continuously, be just directed to the distribution openings 114A corresponding with each workpiece containing box 115 once manage 112 rear workpiece W by input.Therefore in technology in the past, need to be detecting that workpiece W moves to by dropping into pipe 112 the distribution openings 114A that discharges next workpiece W manage 112 outlet by input after.
On the other hand, according to the present invention, the path of the discharge pipe from workpiece reception hole 3 to workpiece containing box 115 is completely independent, therefore as long as light source 11a and photodetector 11b detect workpiece W to discharge and just can make at once to discharge module 81 liftings from workpiece reception hole 3, can make workpiece outlet 8x and the workpiece reception hole 3 of next discharge workpiece W opposed.Therefore, can significantly shorten the time of discharging workpiece W.Middle the discharged workpiece W number that stops of convey table 2 more increases, and the effect of this time shorten is larger.
In Figure 18, when discharge in reception hole e workpiece W time, even if control part 9 is confirmed the workpiece W that makes discharge module 81 liftings of discharge portion 8a, 8b also not have other to discharge from this state.And then control part 9 makes convey table 2 intermittent rotaries, move to the state of Figure 19.
In Figure 19, make the discharge module 81 of discharge portion 8a increase, make the basic 81A of stratum of I be positioned at the height identical with convey table 2.Now, the workpiece W of reception hole i, j is opposed with the outlet 4,3 that should be discharged from (I (4), the I (3) of discharge portion 8a) respectively.
Therefore, control part 9 is controlled driving mechanism 81a, makes the discharge module 81 of discharge portion 8a increase, and makes the basic 81A of stratum of I be positioned at identical height with convey table 2, spray Compressed Gas from squit hole 10 in the same manner with the situation of Fig. 7, this workpiece W is sent into outlet 4,3.Now, the reality that sprays Compressed Gas from squit hole 10 can side by side be carried out for reception hole i, j.
In this case, in conventional art, in the time that workpiece W is expelled to workpiece containing box 115, be just directed to the distribution openings 114A corresponding with each containing box once manage 112 rear workpiece W by input.Therefore, in the case of continuously workpiece W being expelled to different workpiece containing boxs 115, need to move to the next distribution openings 114A that discharges workpiece W by dropping into pipe 112 detecting workpiece is managed 112 outlet by input after.
On the other hand, according to the present invention, the path of the discharge pipe from workpiece reception hole 3 to workpiece containing box 115 is completely independent, therefore, in the case of discharging workpiece W to the multiple workpiece outlet 8x that belong to the identical basic 81A of stratum, can side by side discharge workpiece W.Thus, can significantly shorten the time of discharging workpiece W.The workpiece W number of discharging from the same 81A of stratum in the stopping of convey table 2 more increases, and the effect of this time shorten is larger.Thus, if workpiece outlet the 8x corresponding classification high with occurrence frequency is arranged in identical basic stratum as the outlet 4,3 in Figure 19, can further increase this time shorten effect.
In Figure 19, light source 11a and photodetector 11b detect workpiece W and are admitted to outlet 4,3 from reception hole i, j, and this check result is sent to control part 9, and control part 9 is confirmed the workpiece W that does not have other to discharge under the stage as shown in figure 19.Now, control part 9 makes convey table 2 intermittent rotaries, moves to the state of Figure 20.
In Figure 20, discharge the workpiece W in reception hole d from outlet 10 (I (2) of discharge portion 8b), convey table 2 intermittent rotaries, move to the state of Figure 21.In Figure 21 and Figure 22, the workpiece W not being discharged from, convey table 2 intermittent rotaries, move to the state of Figure 23.In Figure 23, discharge the workpiece in reception hole c from outlet 14 (I (6) of discharge portion 8b), convey table 2 intermittent rotaries, move to the state of Figure 24.
In Figure 24, the outlet 52 (IV (4) of discharge portion 8a) that should discharge the workpiece W in reception hole n declines by the discharge module 81 that makes discharge portion 8a and is opposed with reception hole n.Meanwhile, the outlet 43 (III (3) of discharge portion 8b) that should discharge the workpiece W in reception hole g declines by the discharge module 81 that makes discharge portion 8b and is opposed with reception hole g.
Discharge portion 8a and 8b discharge module 81 lifting respectively separately, and as illustrated in fig. 19, can side by side carry out to being positioned at the sending into of workpiece W of the outlet 8x of the basic 81A of stratum of equal height with convey table 2.Therefore, if make the discharge module 81 of discharge portion 8a decline and make the basic 81A of stratum of IV be positioned at identical height with convey table 2, meanwhile make the discharge module 81 of discharge portion 8b decline and make the basic 81A of stratum of III be positioned at identical height with convey table 2, can, when the workpiece W in reception hole n is sent into outlet 52, the workpiece W in reception hole g be sent into outlet 43.
Like this, there is separately discharge module 81 alone by discharge portion 8a, 8b, can carry out the shortening of the efflux time of workpiece W.
After the discharge of workpiece W in Figure 24, even if control part 9 is confirmed the workpiece W that makes discharge module 81 liftings of discharge portion 8a, 8b also not have other to discharge from this state.Then, control part 9 makes convey table 2 intermittent rotaries, moves to the state of Figure 25.
In Figure 25, the outlet 2 (I (2) of discharge portion 8a) that should discharge the workpiece W in reception hole q rises by the discharge module 81 that makes discharge portion 8a and is opposed with reception hole q.Meanwhile, the outlet 61 (IV (5) of discharge portion 8b) that should discharge the workpiece W in reception hole f declines by the discharge module 81 that makes discharge portion 8b and is opposed with reception hole f.
The lifting of the discharge module 81 of discharge portion 8a and 8b can be carried out respectively, and as illustrated in fig. 19, can be side by side send into workpiece W to the outlet 8x that is positioned at the basic 81A of stratum of equal height with convey table 2, therefore, make the discharge module 81 of discharge portion 8a rise and make the basic 81A of stratum of I be positioned at identical height with convey table 2, meanwhile make the discharge module 81 of discharge portion 8b decline and make the basic 81A of stratum of IV be positioned at identical height with convey table 2.Thus, can, when the workpiece W in reception hole q is sent into outlet 2, the workpiece W in reception hole f be sent into outlet 61.
Then, control part 9 as shown in figure 26, judge discharge module 81 by making discharge portion 8a to decline and should to discharge the outlet 22 (II (6) of discharge portion 8a) of the workpiece W in reception hole m opposed with reception hole m, make the discharge module 81 of discharge portion 8a decline and make the basic 81A of stratum of II be positioned at identical height with convey table 2, the workpiece in reception hole m is sent into outlet 22.
Control part 9 and then as shown in figure 27, judge discharge module 81 by making discharge portion 8a to decline and should to discharge the outlet 39 (III (7) of discharge portion 8a) of the workpiece W in reception hole 1 opposed with reception hole 1, make the discharge module 81 of discharge portion 8a decline and make the basic 81A of stratum of III be positioned at identical height with convey table 2, the workpiece in reception hole 1 is sent into outlet 39.
Now, even if control part 9 is confirmed the workpiece W that makes discharge module 81 liftings of discharge portion 8a, 8b also not have other to discharge from this state.Then, control part 9 makes convey table 2 intermittent rotaries, moves to the state of Figure 28.In Figure 28, the workpiece W of reception hole o, p, r is opposed with the outlet 37,36,34 that should be discharged from (III (5), the III (4) of discharge portion 8a, III (2)) respectively, and the workpiece W of reception hole k is opposed with the outlet 57 that should be discharged from (IV (1) of discharge portion 8b).Therefore control part 9 is side by side sent these workpiece W into each outlet 8x.In this case, also identical with the situation shown in Figure 19, as long as the classification corresponding outlet 8x high with occurrence frequency, distribute to the outlet 37,36,34 being arranged in the identical basic 81A of stratum, the shortening effect of efflux time becomes remarkable.
According to such present embodiment, even in the case of the number of categories of workpiece increases, do not make the number of the workpiece reception hole of convey table increase yet, and do not make to discharge processing speed reduction.And, can at high speed workpiece be expelled in workpiece containing box corresponding to the classification high with occurrence frequency.
In the above-described embodiment, as initial condition, show the basic I of stratum is positioned at and the example of convey table 2 equal heights, but as initial condition, also can make any one basic 81A of stratum of II to IV be positioned at and convey table 2 equal heights, and also can set respectively the initial condition of discharge portion 8a and 8b.
In addition, in the present embodiment, can set up discharge portion 8a and deal with the increase of number of categories.For example in the present embodiment, show the example that is provided with two discharge portion 8a, 8b, even if but be in the very large situations such as 128,256 or 512 at number of categories as the measurement sorter of nearest light-emitting diode, by for each number of categories, the discharge portion corresponding with 32 classification being arranged to 4,8,16, can easily realize with low cost the classification discharge system that can carry out high speed motion.
And, in the above-described embodiment, the number that shows discharge portion 8a, the 8b freely of lifting is respectively two, is provided with the example of 32 workpiece outlet 8x at each discharge portion 8a, 8b, but the number of the number of lifting discharge portion 8a, 8b freely and the workpiece outlet 8x that arranges at each discharge portion 8a, 8b is not defined as respectively two and 32 respectively.
And, in the above description, show the example that whole workpiece outlet 8x of being arranged on discharge portion 8a, 8b is communicated with workpiece containing box 115, but also can be in the situation that for example predefined number of categories be 54, be arranged in 64 workpiece outlet 8x on discharge portion 8a, 8b, make 54 to be communicated with workpiece containing box 115, and do not use 10 remaining workpiece outlet 8x.That is, when establishing n and being natural number, n workpiece outlet 8x is set, the total of the number of the discharge pipe 85 being connected with n workpiece outlet 8x is as long as on number of categories.
And, can will in Fig. 3, form that the basic 81A of stratum, pipe 85, the coil 86, supporting station 87, tube connector 88 of discharging module 81 be summed up and as parts, set up or cut down by connecting these parts and deal with the increase of number of categories or minimizing and workpiece outlet 8x is increased or reduce, can adapt to number of categories and form optimal discharge portion.
This example as shown in figure 29.The basic stratum unit 810 that Figure 29 (a) illustrates includes basic discharge module sheet 81B, pipe 85B, coil 86B, supporting station sheet 87B and tube connector 88B as one.
