It should be noted that, the signal gathering unit 105 of above-mentioned the utility model blocking mechanism, blocking unit 104 phase mutual edge distance when mounted, according to other shapes or the version of bin base plate 103, can also set different far and near distances, those of ordinary skill in the art can understand and need not increase creative work and can be achieved.Therefore, three kinds of distance L that above-mentioned the utility model exemplifies, should as to restriction of the present utility model.
The method of work that the utility model blocking mechanism is described is exemplified further below by Fig. 5 ~ Fig. 7.Fig. 5 ~ Fig. 7 illustrates bin (such as illustrated last bin 101-1, a rear bin 101-2) with the form of carrying out transmitting with its base plate shaped as frame opening direction forward.
1) bin blocks and stops.As shown in Figure 5, under the initial condition of transmission line, the two-position five-way list electric control solenoid valve of control unit instruction blocking unit 104 controls to pass into gas to cylinder, makes cylinder piston rod 5 (i.e. movable barrier portion) be in ejection (rise) state.When moving to piston rod 5 position along conveyer belt 107 proal bin 101-1,101-2, last bin 101-1 meeting stop motion because of the obstruction of piston rod 5, and conveyer belt 107 continues to keep running status.
2) piston rod is regained.As shown in Figure 6, when bin front mechanism (such as certain technique unit) is ready to receive last bin 101-1, control unit can send signal to the two-position five-way list electric control solenoid valve of blocking unit 104, two-position five-way list electric control solenoid valve controls the gas circuit passing into cylinder to change, again pass into gas, piston rod is declined and regains in cylinder.Last bin 101-1, without the obstruction of piston rod, can continue to travel forward along conveyer belt.When last bin 101-1 move to its base plate base be positioned at shown position time, the magnetic induction sensor 105 that correspondence is arranged in base plate base lower position can be triggered.Magnetic induction sensor 105 senses passing through of last bin 101-1, namely can send signal to control unit, shows the motion orientation of last bin 101-1.
3) piston rod ejects.As shown in Figure 7, after magnetic induction sensor 105 sends signal to control unit, control unit can send signal to two-position five-way list electric control solenoid valve, and namely two-position five-way list electric control solenoid valve controls to make cylinder piston rod be in ejection state.Now, due to piston rod be positioned at after the neutral gear position of a bin 101-2 base plate shaped as frame opening (namely meet H
2< L
2< H
1), therefore, the piston rod that the rear bin 101-2 being positioned at last bin 101-1 rear can be ejected stops, and last bin 101-1 then can move forward along conveyer belt direction.So far, blocking mechanism completes and once stops process.
In above-mentioned stop process, the key that can realize stopping smoothly is the distance will controlled well between magnetic induction sensor 105 and piston rod 5, and distance is between the two greater than the base 103-2 width H of bin 101 base plate 103
2, and be less than the side 103-1 length H of bin base plate 103
1.Otherwise between the two apart from too small, last bin 101-1 can knock over by 5, piston rod, and between the two apart from excessive, a rear bin 101-2 likely knocks over and maybe cannot stop a rear bin 101-2 by 5, piston rod, causes a rear bin 101-2 to leak through.And, if during the adjacent motion of two bins 101-1,101-2, set according to the distance between above-mentioned magnetic induction sensor 105 and piston rod 5, can carry out smoothly stopping, when then keeping any distance between two bin 101-1,101-2, all can be stopped by blocking mechanism of the present utility model smoothly.
To last bin 101-1, a rear bin 101-2 with blocking mechanism control mode when transmitting with its base plate 103 shaped as frame opening direction backward, similar with the above-mentioned method exemplified, those of ordinary skill in the art are easy understand, therefore is no longer described in detail.
