The first inclined-plane 6213 is recessed to form one and is positioned at top 6211 and 6212 of lower ends and uses the storage tank 6214 that arranges for top-pushing mechanism 63, top-pushing mechanism 63 comprises one in order to the propulsion arm 631 of pushing tow position at the lower surface 12 of the tablet to be measured 1 in this desired location, and one can drive the cylinder 632 that propulsion arm 631 moves back and forth.Top-pushing mechanism 63 mainly is the tablet to be measured 1 that is parked in the desired location in order to the last a slice of pushing tow, make can the overturn nose 6224 of stop section 6221 of this tablet 1 to be measured, so in the application of reality, also can use the lower surface 12 of rotary swinging arm pushing tow tablet 1 to be measured, even also can directly use with artificial mode the lower surface 12 of hand pushing tow tablet 1 to be measured, perhaps tablet to be measured 1 rear placement a slice ejecting sheet of a slice in the end, this ejecting sheet purpose is exactly that the tablet to be measured 1 of the last a slice of pushing tow does not need to be detected, thereby the processing mode of the last a slice of pushing tow tablet 1 to be measured has many kinds, is not limited in the mode that present embodiment was disclosed.

Next, will illustrate how check implement 200 detects the flow process of tablet 1 to be measured, and be described in detail for the action of feed arrangement 4, turning device 6, loop back device 7 and material collecting device 8.Such as Figure 13, Figure 14 and shown in Figure 15, at first that a pile tablet to be measured 1 is overlapped on the feeding web 41 of feed arrangement 4, particularly, before being positioned at 44 of both sides guide plates and stop block 42, when beginning to start feed arrangement 4, feeding web 41 can be carried these tablets 1 to be measured along throughput direction I, the tablet to be measured 1 that is positioned at lowermost end can not be subjected to the block of stop block 42 and via gap 43 towards carrying belt body 311 directions to move, all the other 1 of tablets to be measured can be subject to stopping of stop block 42 and can't move as shown in figure 15, after the tablet to be measured 1 of lowermost end passes through gap 43 fully, all tablets 1 to be measured that are positioned on this tablet 1 to be measured all can be subjected to gravity and the distance of a past thickness T of bottom offset, similarly, the tablet to be measured 1 that contacts feeding web 41 this moment also no longer is subject to the block of stop block 42, and moves toward feedway 3 by gap 43 in aforesaid mode.Utilize the setting of this feed arrangement 4, do not need to use very complicated mechanism design, cost that also need not be expensive, then can reach and once put multi-disc tablet 1 to be measured, allow these tablets 1 to be measured can automatically be delivered to one by one the conveying belt body 311 of feedway 3, and when optical detection apparatus 5 (seeing Fig. 2) detects, can an a slice be detected.

As shown in Figures 1 and 2, enter after the conveying belt body 311 of feedway 3, carry belt body 311 can continue tablet 1 to be measured is carried along throughput direction I, when tablet 1 to be measured is transported to below by optical detection apparatus 5, the conveying that this tablet 1 one side to be measured is subject to carrying belt body 311, one side is subject to the linear scanning of optical detection apparatus 5, make the image of the upper surface 11 of this tablet 1 to be measured can be sent to computer for analysis system (not shown), judge whether the upper surface 11 of this tablet 1 to be measured has flaw.

Next, the tablet to be measured 1 that detected by optical detection apparatus 5 can be transferred belt body 311 to be continued to send into turning device 6 along throughput direction I, so follow-up will how tablet 1 upset to be measured being described in detail for turning device 6:

Such as Fig. 2 and shown in Figure 16, carry belt body 311 can sequentially will finish on the carrying surface 611 of delivery element 61 that tablet to be measured 1 that upper surface 11 detects is delivered to turning device 6, delivery element 61 can be carried tablet 1 to be measured gradually along throughput direction I backward, when the center of gravity of this tablet 1 to be measured that is positioned at rearmost end exceeded rear end 613, this tablet 1 to be measured namely can be subject to the impact of gravity and down drop towards the first inclined-plane 6213.Then, as shown in figure 17, this tablet 1 to be measured down drops and when lower surface 12 touches the first inclined-plane 6213, can be subject to the guiding on the first inclined-plane 6213 and glide, when being subjected to stop section 6221 block, the first end 13 of tablet 1 to be measured just stops to slide, the lower surface 12 of this tablet 1 to be measured can be posted by on the first inclined-plane 6213, the second end 14 of this tablet 1 to be measured can protrude out and be higher than carrying surface 611, and the first inclined-plane 6213 parts protrude out carrying surface 611 tops, at this moment, tablet 1 to be measured is positioned at the desired location.

Such as Figure 18, Figure 19 and shown in Figure 20, another tablet 1 ' to be measured that is adjacent in this tablet to be measured 1 the place ahead in desired location can move along throughput direction I, and gradually near this tablet 1 to be measured, the first end 13 ' of this another tablet 1 ' to be measured can this tablet 1 to be measured of pushing tow lower surface 12 protrude out the position of carrying surface 611 tops, make this tablet 1 to be measured take first end 13 as fulcrum along arrow II I direction rotation, when this tablet 1 to be measured rotates to upper surface 11 conflict nose 6224, this tablet to be measured 1 can be take position that upper surface 11 and nose 6224 are conflicted as the fulcrum rotation, make the first end 13 of this tablet 1 to be measured move apart stop section 6221, the upper surface 11 of tablet 1 to be measured is resisted against the second inclined-plane 6222 simultaneously, whereby, so that tablet to be measured 1 can overturn smoothly and cross the nose 6224 of stop section 6221 and rotate on the second inclined-plane 6222.This tablet 1 to be measured can 6223 slips along the second inclined-plane 6222 towards the disposal area.

At last, as shown in figure 21, when tablet 1 landing to be measured during to disposal area 6223, the second end 14 of block wall 6226 meeting blocks tablet 1 to be measured, slide backward to limit tablet 1 to be measured, this tablet 1 to be measured can be fallen on the horizontal bottom wall 6227, and at this moment, the upper surface 11 of tablet 1 to be measured is posted by horizontal bottom wall 6227 and lower surface 12 up.In addition, tablet 1 ' to be measured then can slide to down the desired location, and lower surface 12 ' is posted by the first inclined-plane 6213, the second ends 14 ' and protrudes out carrying surface 611 and lower surface 12 ' part and protrude out carrying surface 611 tops, for lower a slice tablet 1 ' pushing tow to be measured.By above-mentioned inversion principle, the to be measured tablet 1 of position in the desired location can be subject to adjacent tablet to be measured 1 pushing tow and finish upset, so that these tablets 1 to be measured can overturn and be stacked on as illustrated in fig. 22 in the disposal area 6223 in order.Utilize simple mechanism design, just can reach the rollover effect of tablet 1 to be measured, not only can effectively reduce the board cost, also can reduce the time of spending at installing optical detection apparatus 5.

As shown in figure 22, when last a slice tablet 1 to be measured is positioned at the desired location, because other tablet 1 to be measured can this tablet 1 to be measured of pushing tow, so utilize the cylinder 632 of top-pushing mechanism 63 to drive the lower surface 12 that propulsion arm 631 removes this tablet 1 to be measured of pushing tow, make this tablet to be measured 1 upset and cross the nose 6224 of stop section 6221 and rotate on the second inclined-plane 6222, and by 6222 guidings of the second inclined-plane and slip in the disposal area 6223.
