The specific embodiment
The utility model is described in further detail below in conjunction with specific embodiment.
Such as Fig. 1, shown in Figure 3, a kind of electricity drives the high-speed switch reversing arrangement, comprise: traveling gear 2, it is shaft-like that described traveling gear 2 is level, and the bar two ends respectively are provided with a roller vertical with bar, two rollers roll in the track of pair of parallel, the bar overcoat has pushing block 1, and described pushing block 1 can slide along bar, and described pushing block 1 bottom is provided with a pushing block walking pin 3; Walking pin guided way, described guided way is positioned at pushing block 1 below and vertical with traveling gear 2, and with guide groove 4 parallel and linkings, described walking pin 3 can enter in the guide groove 4 simultaneously; Switch reversing mechanism 6, described switch reversing mechanism 6 comprises the track switch pedestal, and the track switch pedestal is provided with shift fork 8, the shift fork actuating device, described shift fork actuating device shift fork 8 is stirred between guide groove 4 and another guide groove 5, makes walking pin 3 enter another guide groove 5 from guide groove 4 commutations; Described shift fork 8 is strip, one end is fixed on two guide groove cross connections place by rotating shaft, the other end can drive by electricity and make arcuate movement along rotating shaft, fiddles with between two guide grooves, and the type of drive of described shift fork actuating device is that o drives.Described shift fork 8 adopts the alloy steel material, and roughness of surface is below 2 μ m.Described track switch pedestal adopts the non-metal Composite, and roughness of surface is below 2 μ m.
When the utility model electricity drives the work of high-speed switch reversing arrangement, such as Fig. 1, shown in Figure 3, shift fork is positioned at the position of guide groove 4 antethecas, external force promotes traveling gear 2 and walks along the first guided way, traveling gear drives pushing block and walks together, pushing block drives walking pin 3 in guide groove 4 interior movements, when walking pin 3 moves to the position of switch reversing mechanism, if the sorting instruction that system gives is to continue to walk forward along guide groove, it is motionless that then shift fork 8 keeps the position of guide groove 4 antethecas under the control of drive motor, another guide groove 5 is blocked, walking pin 3 is from continuing forward walking along guide groove 4, and object 7 walks on along former direction under the drive of traveling gear 2; If the sorting instruction that system gives will be along another guide groove walking, then shift fork 8 is upwards stirred 20 ° under the control of drive motor, walking pin 3 craspedodrome passages are blocked by shift fork 8, the walking pin turns to and walks along another guide groove 5, object 7 walks on after turning to 20 ° under the promotion of traveling gear 2, until be sorted.
The utility model utilizes o to control the spinfunction of shift fork, as shown in Figure 4, by coil is switched on, can realize that shift fork is at position A, be rotated transposition between the B, when the coil no power, because the effect of locating dowel pin, shift fork is in the B position all the time, when giving the energising of coil forward, shift fork can rotate the point to A by the B point, when shift fork during at the A point to the logical oppositely electricity of coil, then shift fork can rotate the point to B by the A point, and is like this then realized the spinfunction of shift fork by o, in addition, because permanent magnet is the N utmost point when the O point, so no matter in energising and cold situation, shift fork all is in a kind of critical conditions when rotating to the O point, shift fork can't be stablized and stops during this critical conditions, therefore can avoid shift fork in rotary course, to stop at the middle phenomenon of track by the method, thereby walking pin and the shift fork of fundamentally having stopped high-speed mobile produce the hidden danger that bump causes device damage, guaranteed simultaneously the each accuracy of rotating of shift fork and putting in place property.
Simultaneously, by finite element analysis and strength of material/specificity analysis, make shift fork and switch mechanism, and o 10 is fixed on the switch mechanism, energising and power down function by o, realize that shift fork is rotated to B point or B point by A point and rotate the function of ordering to A in switch mechanism, to reach the closure function of turnout rail guide groove 4 and another guide groove 5, finally realize the track switch purpose that commutates.
The on-rectilinear movement pattern because the mode of motion of shift fork adopts rotary, revolving angle is very little, only is 20 °, only gets final product for 8ms so that rotate the needed time, and switching rate is much larger than adopting the air cylinder driven shift fork to carry out the required 30ms of straight-line motion.When the user requires as 180m/min (3m/s) to logistics sorting delivery speed, at this moment, as shown in Figure 5, spacing between the two pushing blocks walking pin is 100mm, time by shift fork only is 33.3ms, adopts the shift fork of air cylinder driven to carry out the back and forth 60ms that is required to be of one of straight-line motion, passes through the needed times of shift fork much larger than two pushing blocks walking pins, therefore existing air cylinder driven shift fork can't use, and electricity of the present utility model drives the rotation shift fork and can finish and stir commutation function.
Use the theoretical velocity of the slide block type sorter of the utility model track switch reversing arrangement to reach as high as 3m/s(180m/min), solved theoretically the root problem of sorting speed.
On the slide block type sorter, adopt the switch reversing mechanism of using the utility model technology to substitute the direction reverser of present air cylinder driven, can realize that traveling gear is in the high speed commutation function of switch location, simultaneously so that percentage error and the fault rate of track switch commutation greatly reduce, no matter theoretically or in the reality, the phenomenon of pushing block walking pin and shift fork collision all can not occur, so that use the running velocity of the slide block type sorter of the utility model track switch reversing arrangement, sorting efficient, life cycle, the working service cost all has significantly improvement than present similar sorting product.
