The specific embodiment

Embodiment one:

Present embodiment is the specific embodiment of intelligent vehicle quickly ration loading method, and Fig. 1 is the operational process scheme drawing of present embodiment.The hardware that present embodiment relates to comprises: storage bin, storage bin batching gate, quantitative storehouse, quantitative storehouse discharge gate, weighting apparatus, flexible loading chute, its installation site as shown in Figure 2.The whole service process is as follows:

Start loading process, enter initial condition.Initial condition is the initial initial point of whole process, and before entering initial condition, whether the each several part that system can automatic checkout equipment is normal, to regular the calibrating of weighting apparatus, then enters initial condition after all are normal according to the time gap of prior setting.

Whether weighting apparatus detects material in the quantitative storehouse, promptly measure its quantity if any material.This step is very important in continuous loading process, because the inventory that tends to occur in the quantitative storehouse in the loading process of complexity is answered cargo-carring amount above waiting to load vehicle, so just must adorn some and stay, quantitatively in the storehouse remaining material often be arranged, must measure.

Entrucking material quantity is treated in input to system.This step is to inform how many materials that the computer control system plan is removed stage makeup and costume to vehicle to be loaded has, so that computer system is determined following operating procedure.

Open storage bin batching gate, material is imported quantitative storehouse, weighting apparatus carries out the dynamic increment metering to material.This step is that storage bin begins to quantitative storehouse convey materials, weighting apparatus also begins the material of weighing input simultaneously in course of conveying, result according to weighing, by the gradient closed shutter, progressively slow down feeding, in the hope of reaching the purpose of accurate feed proportioning, promptly close storage bin batching gate in case reach scheduled volume.

The material input reach treat the entrucking inventory or quantitatively the storehouse fill, close the storage bin gate.This step has comprised three kinds of situations: a kind of is to treat the capacity of the loading of freight waggon less than quantitative storehouse, and then quantitative storehouse is not filled and just stopped to have adorned material; Second kind of situation is to treat that the loading of freight waggon equals the capacity in quantitative storehouse, and then quantitative storehouse is filled and stopped to adorn material; The third situation is to treat the loading of freight waggon greater than the quantitative capacity in storehouse, and then quantitatively the storehouse is filled and stopped to adorn material, treat quantitative storehouse unstow after load measurement again so that reach the loading of freight waggon for the treatment of of expectation.

Weighting apparatus carries out static accurate measurement to the material in the quantitative storehouse.Because the weighing in loading process can only be used for accurate feed proportioning.This weighing commercial be to be nowhere near, so must carry out static metering, just can reach the measurement standard of trade settlement.

Be loaded vehicle and enter the loading parking stall, flexible loading chute is stretched to by entrucking compartment ledge height.Because the size dimension difference of automobile, height are also different.And the method from the top loaded material that present embodiment adopts, for adapt to the open height that goes out that large-sized automobile then improves quantitative storehouse as far as possible, if the too high meeting of delivery port directly influences loading quality for small-sized vehicle, therefore be provided with flexible loading chute specially, quantitatively the discharging opening in storehouse is fixed, extended flexible mouth is changeable, no matter the final material outlet of vehicle size all extends to the ledge of automobile bodies, ledge is the backplate of holding up around the transport truck compartment.

Open quantitative storehouse discharge gate, unload in being loaded vehicle and put material, weighting apparatus carries out dynamic decrement metering to material.In being loaded vehicle, unload when putting material after quantitatively the storehouse discharge gate is opened and also will monitor unloading the material process, reason is the complexity in loaded material, imported computing machine though plan quantitative loading sometimes, but running modification carrying capacity, or the vehicle that enters is not calculated vehicle, carrying capacity changes, and present embodiment can be dealt with, and changes to be embodied in following steps.

Be divided into two kinds of situations of a, b according to unloading material situation different step:

A. reach and treat the entrucking inventory, close quantitative storehouse discharge gate.When plan changed, former carrying capacity was just closed quantitative storehouse discharge gate greater than answering carrying capacity when then quantitatively material is unloaded in the storehouse to requirement.

Weighting apparatus carries out static accurate measurement to the leftover materials in the quantitative storehouse.At this moment metering is in order to calculate the loading of freight waggon, because quantitatively the storehouse is unloaded material amount before and has been passed through accurate measurement, be known quantity, as long as the leftover materials amount in the quantitative storehouse of accurate measurement just can accurately calculate the loading of freight waggon, to reach the precision of trade settlement.

B. quantitatively unstow in the storehouse, treats the entrucking inventory if reach, and closes quantitative storehouse discharge gate and enter next step, do not treat the entrucking inventory if reach, and closes quantitative storehouse discharge gate, gets back to and open storage bin batching gate, material imported the step in quantitative storehouse.If unstow quantitative storehouse according to plan, reach and answer the loading of freight waggon, unstowing is normal program, illustrates and has loaded vehicle according to plan, answers carrying capacity if all unstow also not reach in still quantitative storehouse, will get back to the step in the quantitative storehouse of reloading, and remaining amount dress is neat.

Flexible loading chute withdrawal is loaded vehicle and leaves the loading position, and loading process is got back to initial condition.This step is to load to reach to answer carrying capacity, and flexible loading chute is withdrawn into the initial position, and loading process is got back to initial condition, can carry out next round and load.
