Refer to Fig. 5, Fig. 5 is the locations of structures schematic diagram of blocking unit elastomer buffer gear in Fig. 4.Buffer gear 9 and 10 is arranged on the stop stress surface (i.e. blocking surface and the stop back side) of described stopper 5, and is positioned at groove 8 fit clearance of described stopper 5 and described blocking unit support 7.In order to more clearly represent buffer gear 9 and 10, in Figure 5 described stopper 5 being made transparent processing, to be shown by buffer gear 9 and 10, please correct understanding be give.As shown in Figure 5, described buffer gear 9 and 10 can be designed as and comprises elastomeric form, such as elastomeric pad or other there is flexible suitable means, also can be and there is flexible elastomer combiner.In the present embodiment, described buffer gear 9 and 10 have employed elastomeric components form.Described elastomeric components 9 and 10 comprises circular flexible cushion block 9 and the round and elastic packing ring 10 that Juxtaposition and Superimposition is arranged; Described stopper 5 blocking surface and stop that the back side is inwardly processed with blind round hole (i.e. the second groove, diagram omission).Described elastic washer 10 and cushion block 9 are put into described blind hole successively, are formed matched in clearance in blind hole side.Further, the degree of depth of blind hole will be slightly less than gross thickness when described elastic washer 10 and cushion block 9 stack, to make described cushion block 9 slightly can give prominence to the side of described stopper 5, and forms interference fit with groove 8 inwall of the described blocking unit support 7 of respective side.As an embodiment, described flexible cushion block 9 can adopt the POM plastic materials processing with certain degree of hardness to make.
Please continue to refer to Fig. 5.The elastomeric components be made up of cushion block 9 and elastic washer 10, one group can be respectively arranged in the middle part of the blocking surface of described stopper 5 and the stop back side, when described stopper 5 rise stops, cushion block 9 and elastic washer 10 are dissolved in the middle part in groove 8, the balance of described stopper 5 can be kept, unlikely horizontal skew back.As preferably, in the present embodiment, at the blocking surface of described stopper 5 and can stop that each horizontal symmetrical in the back side arranges two elastomeric components 9 and 10, the i.e. sub-assembly (be positioned at diagram stopper and stop that two groups of cushion blocks at the back side and the sub-assembly of elastic washer do not show) of two groups of cushion blocks 9 and elastic washer 10, the sub-assembly of two groups of cushion blocks 9 and elastic washer 10 is dissolved in groove 8 symmetrically, therefore can play balanced action when stopping buffering better.
Please continue to refer to Fig. 5 and Fig. 6.When the height of described stopper 5 should ensure that its rise can stop bin base plate, still some is dissolved in the groove 8 of described blocking unit support 7 in below.Further, be arranged on described stopper 5 blocking surface and stop that the elastomeric components 9 and 10 at the back side should ensure be dissolved in equally when described stopper 5 rises in the groove 8 of described blocking unit support 7, to form buffer stop between stopper 5 and groove 8.After setting height(from bottom) distance when setting described stopper 5 and landing between its upper end and bin base plate lower surface, can easily realize above-mentioned requirement.
Referring again to Fig. 6.Above-mentioned blocking unit support 7 is installed and is connected to the inner side of described transmission line, specifically can screw be used to be connected with described transmission line by the installing hole of its kink on blocking unit support 7, and inside the conveyer frames 106 being fixedly mounted on transmission line.When mounted, whole blocking unit 104 (comprising blocking unit support 7) should and described bin base plate 103 lower surface between in height keep certain clearance distance, stopper 5 after blocking unit support namely shown in Fig. 47 and landing should lower than the lower surface of described bin base plate 103, in order to avoid described bin 101-1,101-2 its base plate 103 when moving forward touches any part of blocking unit 104.
Also combine please continue to refer to Fig. 6 and consult Fig. 4, Fig. 5.When described in control unit instruction, two-position five-way list electric control solenoid valve 3 passes into gas to cylinder 4, cylinder piston rod rises, by stopper 5 jack-up.Now, described elastomeric components 9 and 10 will be followed stopper 5 and be risen, but still be dissolved in groove 8.When target bin marches to stopper 5 place, namely stopped by stopper 5.Further, stop the compressive deformation of the elastic washer 10 at the back side by being arranged on stopper 5, when part is unloaded except stopping, bin is to the frontal impact power effect of stopper 5; Simultaneously, a pair elastomeric components 9 and 10 being arranged on stopper 5 blocking surface is subject to from stopping the power that groove 8 inwall at the back side passes over, make the elastic washer 10 compressive deformation contraction then in this side blind hole, and resisted by the reverse buffering of this side groove 8 inwall, further reduce impulsive force during stop.Like this, play buffering effect by the transmission of power between stopper 5 and elastomeric components 9 and 10, groove 8, the impulsive force produced when stopper 5 resistance stops bin can be absorbed when stopping, reducing the vibration that impact process produces; Cushion block 9, elastic washer 10 are arranged in stopper blind hole; the bin impulsive force that stopper 5 can be subject to is delivered on blocking unit support 7 further; to reduce shearing force that stopper 5 is subject to and moment of flexure; blocking unit 104 can be protected while realization buffering bin, thus improve resistance to overturning and the function lasting effectiveness of blocking unit 104.Have employed the flexible cushion block 9 of POM in the elastomeric components 9 and 10 of buffer gear, can avoid causing wearing and tearing to groove 8, to extend its useful life.After elastomeric components 9 and 10 is installed, and define interference fit between groove 8 inwall, instantaneously the impulsive force of bin can be rapidly to blocking unit support 7 in stop and transmit, and the swing (vibration) of cylinder piston rod can be reduced.
Certainly, above-mentioned cushion block 9 and elastic washer 10 are not limited to circle, can be other any suitable shapes, as long as cushion block 9 along the upper and lower relative sliding of blocking unit rack groove 8 inwall, and can be dissolved in groove 8 when stopper 5 rises, effectively play cushioning effect; Stopper 5 also can be other shapes that at least blocking surface has upright side walls, and groove 8 inwall can match with stopper 5 profile, when it rises, stably can touch bin base plate 103 side and form buffer stop.
Please continue to refer to Fig. 6.The setting of retention device of the present invention, is applicable to each bin 101-1,101-2 and is laterally crossed on the form (please refer to illustrated bin direction) conveyer belt 107 carrying out transmit with its base plate 103 shaped as frame opening.Each bin is when transmitting, may be close to parallel transmission, also may be keep different distances each other, and due to the distance between each bin and disunity, and the side crossbearer of bin base plate is between transmission line, therefore, in order to realize the automatic control stopped one by one bin, must first determine magnetic induction sensor sense last bin by signal time, what position a rear bin is specifically in.In this case, the mode (i.e. first, second magnetic induction sensor) that two magnetic induction sensors are set must be adopted.If only adopt a magnetic induction sensor, when this magnetic induction sensor senses passing through of last bin, because determining what position a rear bin is in, the situation of a rear bin may be knocked over or leak through to a rear bin by the stopper that will be in commitment positions.
In view of this, the present invention adopts two shown in Fig. 6 magnetic induction sensor 105-1,105-2 and blocking unit 104 to carry out the mode coordinated, and according to the transmission orientation feature of bin base plate 103, the efficiency configure between two magnetic induction sensors 105-1,105-2 and blocking unit 104 is set.In order to clear expression, in fig. 2, the side 103-1 of bin base plate 103, base 103-2 size are demarcated.As shown in Figure 2, the bottom side length scale of described base plate is decided to be H1, side width calibration is H2.Thus determine, between the following stated first, second magnetic induction sensor 105-1,105-2 and blocking unit 104 (i.e. stopper), distance is set mutually:
Described front and back between first, second magnetic induction sensor 105-1,105-2 inside described transmission line arrange distance L1 and are: H1 < L1 < H1+H2; Further, the front and back between described second magnetic induction sensor 105-2 and the described stopper 5 of described blocking unit 104 inside described transmission line arrange distance L2 and are: H2 < L2 < H1-H2; Wherein, H1 for the base length of the described bin base plate shown in Fig. 2, H2 be the side width of described base plate.Meanwhile, described first magnetic induction sensor 105-1 is arranged on can senses inside transmission line that described bin base plate 103 side passes through lateral attitude arbitrarily; Described second magnetic induction sensor 105-2 is arranged on can sense described bin base plate 103 except lateral attitude inside the transmission line that passes through of respective side 103-1 part that base 103-2 occupies except position.
According to the setting of above-mentioned distance, when can be in the state being close to parallel transmission and keeping different distance between bin, can both reliably stop target bin.
It should be noted that, first, second magnetic induction sensor 105-1, the 105-2 of the invention described above retention device, 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 and the horizontal installation site inside transmission line, those of ordinary skill in the art can understand and need not increase creative work and can be achieved.Therefore, the distance setting form that the invention described above exemplifies, should not be construed as limitation of the invention.
A kind of method of work that retention device of the present invention is described is exemplified further below by Fig. 6 ~ Fig. 9.Fig. 6 ~ Fig. 9 illustrates bin (the last bin 101-1 of such as illustrative exemplary, a rear bin 101-2), and with being laterally crossed on form conveyer belt 107 carrying out transmit with its base plate 103 shaped as frame opening, (namely bin transmits in side direction mode.
1) bin blocks and stops.As shown in Figure 6, 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 be in ejection (rise) state, by stopper 5 (i.e. movable barrier portion) jack-up; Meanwhile, the first magnetic induction sensor 105-1 is in opening all the time, and the second magnetic induction sensor 105-2 is temporarily in closed condition, and it needs to be controlled to open and close by control unit.When bin 101-1, the 101-2 of travel forward along conveyer belt 107 (diagram dextrad) move to stopper 5 position of blocking unit 104, last bin 101-1 meeting is because the obstruction stop motion of the stopper 5 risen, and conveyer belt 107 continues to keep running status.Simultaneously, the elastomeric components be made up of cushion block and elastic washer that stopper 5 blocking surface and the stop back side are arranged has given play to cushioning effect, reduce the impulsive force of bin to blocking unit 104, and this power is delivered to rapidly on blocking unit support 7 by elastomeric components, thus reduce impact to cylinder piston rod, and the cell silicon chip in bin can be avoided to be subject to hard hit and impaired.
2) first, second magnetic induction sensor is triggered.As shown in Figure 7, when bin front mechanism (such as certain technique unit) is ready to receive last bin 101-1, signal is sent to the two-position five-way list electric control solenoid valve of blocking unit by control unit, 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 regain in cylinder, and drive stopper 5 decline to be dissolved in the groove of blocking unit support.Last bin 101-1, without the obstruction of stopper 5, can continue to travel forward along conveyer belt.Then, when last bin 101-1 move to the last side of its base plate 103 arrive the first magnetic induction sensor 105-1 position time, the first magnetic induction sensor 105-1 that correspondence is arranged in base plate 103 side lower position can be triggered.This applies electromagnetic induction principle, and certainly, bin base plate 103 also at least should have magnetic metal material inductor at correspondence position, senses passing through of bin base plate to enable magnetic induction sensor.In the embodiment stated on the invention, illustrate magnetic induction sensor as signal gathering unit.And the sensing realizing passing through bin is actual a lot of mode.Therefore, according to the difference of sensor type, its induction mode also can be different, therefore should not be construed as the restriction to implementation of the present invention.First magnetic induction sensor 105-1 senses passing through of last bin 101-1, namely can send signal to control unit, shows the motion orientation of last bin 101-1.Now, control unit can send signal to the second magnetic induction sensor 105-2, originally the second magnetic induction sensor 105-2 being in closed condition is activated (in the figure 7, because the second magnetic induction sensor 105-2 is sheltered from by bin base plate 103, in order to clearly indicate the position of the second magnetic induction sensor 105-2, carry out analysing and observe process to the local residing for the second magnetic induction sensor 105-2 in the drawings).The key completing this process be between first, second magnetic induction sensor 105-1,105-2 arrange distance L1 to meet the base length H1 that is greater than bin base plate 103 and be less than a base length H1 and side width H2 with value (namely meeting aforesaid H1 < L1 < H1+H2).Otherwise distance is between the two too small, then after likely causing, a bin 101-2 is knocked over by stopper 5; Between the two apart from excessive, a rear bin 101-2 likely knocks over and maybe cannot stop a rear bin by stopper 5, causes a rear bin to leak through.
3) stopper ejects.As shown in Figure 8, bin 101-1,101-2 continues to travel forward along conveyer belt.When after a bin 101-2 base plate 103 front side edge front end by being arranged in the second magnetic induction sensor 105-2 of side-lower in transmission line (in fig. 8, because the second magnetic induction sensor 105-2 is sheltered from by bin base plate 103, in order to clearly indicate the position of the second magnetic induction sensor, carry out equally analysing and observe process to the local residing for the second magnetic induction sensor in the drawings) time, after second magnetic induction sensor 105-2 senses, a bin 101-2's passes through, signal can be sent, the motion orientation of a bin 101-2 after showing to control unit.After the second magnetic induction sensor 105-2 sends signal to control unit, control unit can send signal to two-position five-way list electric control solenoid valve.Namely two-position five-way list electric control solenoid valve controls to make cylinder piston rod be in ejection state, and again by stopper 5 jack-up.The key completing this process is the side width H2 that distance L2 between the second magnetic induction sensor 105-2 and stopper 5 is greater than bin base plate 103, and is less than the difference (namely meeting aforesaid H2 < L2 < H1-H2) of a base plate base length H1 and side width H2.Otherwise between the two apart from too small, after causing, a bin 101-2 is knocked over by stopper 5; Between the two apart from excessive, after causing, a bin 101-2 is knocked over by stopper 5 or a rear bin is leaked through by stopper, is not stopped.
4) block stop after a bin.A last bin 101-1 and rear bin 101-2 continues to travel forward along conveyer belt.When base plate 103 front side edge of a rear bin 101-2 move to cross the second magnetic induction sensor 105-2 position time, the second magnetic induction sensor 105-2 by generation trailing edge signal, and sends to control unit; Control unit closes the second magnetic induction sensor 105-2 immediately, makes it standby, carries out startup sensing for use in each to needing to hinder the target bin stopped.When base plate 103 back side edge of a rear bin 101-2 moves to stopper 5 position, namely a rear bin 101-2 can be blocked by the stopper 5 risen and stop, and last bin 101-1 then can continue to travel forward along conveyer belt.The impulsive force that after the same available buffer of buffer gear of blocking unit, a bin produces, protects the cell silicon chip in bin and blocking unit.So far, retention device completes and once stops process.
In above-mentioned stop process, the key that can realize stopping smoothly is the distance will controlled well between first, second magnetic induction sensor 105-1,105-2 and stopper 5.And, if during the adjacent motion of former and later two bins 101-1,101-2, set according to the distance between above-mentioned magnetic induction sensor 105-1,105-2 and stopper 5, can carry out smoothly stopping, when then keeping any distance between two bin 101-1,101-2, all can successfully be stopped by retention device of the present invention.
In sum, the present invention arranges first, second magnetic induction sensor as first, second signal gathering unit and the blocking unit that is made up of gas circuit electric control solenoid valve (such as two-position five-way list electric control solenoid valve) and cylinder by the inner side of the material transmission system transmission line at crystal silicon solar batteries production line by certain longitudinal separation, and the folding of gas circuit electric control solenoid valve is controlled by control unit, control the conversion passing into cylinder gas circuit, make the piston rod of cylinder drive movable barrier portion (i.e. stopper) to rise or fall, when bin is so that two of its shaped as frame base plate horizontal two synchrome conveying belts being crossed on transmission line of wide sides to transmit successively, can control unit receive the last bin that the first signal gathering unit senses by signal time, start secondary signal collecting unit, and beyond the position, base plate base receiving the rear bin that secondary signal collecting unit senses respective side part by signal time, control makes movable barrier portion rise, the base plate side of a rear bin is stopped, after making, a bin and subsequent institute's material rack stop reach on the synchrome conveying belt of transmission line, thus realize controlling the transmitting procedure of bin, can at conveyer belt still under the condition of running, target bin is stablized, stop exactly, and can after stop is removed, make bin still can according to pre-determined route even running.Retention device provided by the invention; compact conformation; smooth running; online work can be realized; and elastomer buffer gear is set by the blocking surface in movable barrier portion and the stop back side; the horizontal impact power that when can effectively reduce stop, bin produces blocking unit, avoids making bin vibration occur and damage cell piece, and protects blocking unit.Therefore, the present invention can meet buffer stop action request when transmitting crystal silicon solar transfer matic silicon chip bin well.
