The utility model comprises following four kinds of mode of operations.

Pattern one:

In the previewing system I, preliminary examination person by grade dress basket, writes tobacco grower's card with the basket logarithmic data by hand-held rf read-writedevice 13 with tobacco leaf grading that the tobacco grower sells; Then the tobacco grower is blocked and insert radio-frequency card card-reading apparatus 3-2 and read the tobacco grower and block data; Simultaneously, the cigarette basket is put tobaccoleaf conveying equipment 5 and is carried out cigarette basket counting by infrared identification counting assembly 3-1; Transaction warehouse-in system IV is obtained the tobacco grower bymain frame 1 and is blocked data and cigarette basket data, sends video data to light-emitting diode display 3-3 after data processing; Light-emitting diode display 3-3 instant playback tobacco grower's information and cigarette basket counting.When the whole inputs of current tobacco grower's cigarette basket finish, can remove tobacco grower's card of current tobacco grower from radio-frequency card card-reading apparatus 3-2.

The cigarette basket is sent to deciding grade and level system II through tobaccoleaf conveying equipment 5, when deciding grade andlevel equipment 4 has measured the cigarette basket when reaching by cigarette basket detecting device 4-3 and interface thereof, by discharging the passive contact of control output, the 5 waits deciding grade and level out of service of tobacco leaf conveying equipment; Deciding grade and level person defines the level to tobacco leaf, and with the deciding grade and level input keyboard 4-1 input of tobacco leaf grade by deciding grade andlevel equipment 4, errorless through confirming, warehouse-in to be transacted such as deciding grade andlevel equipment 4 system IV is collected data bymain frame 1; Confirm transaction warehouse-in system IV when deciding grade andlevel equipment 4 and correctly receive data, the passive contact of promptly closed control output, tobaccoleaf conveying equipment 5 starts operation the cigarette basket is moved to weigh weighing system III and transaction warehouse-in system IV.

The cigarette basket moves to the weighing system III of weighing through tobaccoleaf conveying equipment 5, when the cigarette basket enters infrared detectingdevice 8, carryoperation controller 10 to record the cigarette basket and arrive weighing platform 6-1, will carryoperation controller 10 output control passive contact releases, it is to be weighed that tobaccoleaf conveying equipment 5 is out of service etc.; Electronic-weighing instrument 6-3 records the tobacco leaf actual weight, and weight data is sent to transaction warehouse-in system IV bymain frame 1; IV is received the tobacco leaf weight data when transaction warehouse-in system, confirm errorless, handle through system data, tobacco grower's information, tobacco leaf grade, tobacco leaf weight, unit price, the amount of money of this basket tobacco leaf is shown that to tobacco leaftransaction bulletin screen 2 instant transmissions voice synchronous is reported bymain frame 1; The tobacco grower then stops purchase as having objection, and tobacco leaf moves back cigarette by moving back cigarette channel; The tobacco grower sells as agreeing, then tobacco leaf enters the warehouse-in passage; When the closing the transaction of current cigarette basket tobacco leaf, transaction warehouse-in system IV carriesoperation controller 10 with the passive closing of contact to carryingoperation controller 10 to send startup command, and conveyingequipment 5 continues operation work, waits for the arrival of next cigarette basket.

The radio-frequency card card-reading apparatus 3-2 that obtains the previewing system I when transaction warehouse-in system IV has withdrawn current tobacco grower's card, and all the transaction of cigarette basket tobacco leaf is finished, prints this family this hypo-tobacco leaf of tobacco grower schedule of dealing and writes tobacco grower's card by radio-frequencycard card reader 19 by printer 18.The tobacco grower can be with tobacco grower's card and schedule of dealing knot cash.

Pattern two:

Pattern two is preliminary examination, deciding grade and level two line parallel work-flows.Do not usepreliminary examination device 3 in the previewing system I, deciding grade and level system II is used Card Reader type detecting device, uses tobacco grower's coding card and cigarette basket (coding) to block good for both sides card.

Preliminary examination person is tobacco grower's tobacco leaf grading in the previewing system I, and packing into by grade is loaded with the cigarette basket of cigarette basket (coding) card; Read tobacco grower's card information by hand-held rf read-writedevice 13, tobacco grower's information and cigarette basket number are write tobacco grower's coding card, tobacco grower's coding card is placed in first cigarette basket of input.

The Card Reader type deciding grade and level device of deciding grade and level system II is read cigarette basket (coding) card by the middle distance card reader, the 5 wait deciding grade and level out of service of tobacco leaf conveying equipment; Deciding grade and level person picks up tobacco grower's coding card in first cigarette basket and is positioned over closely on the card reader 4-2, treats after deciding grade andlevel equipment 4 reads tobacco grower's information tobacco grower's coding card to be put back in first cigarette basket again; And to tobacco leaf deciding grade and level, with the deciding grade and level input keyboard 4-1 input of tobacco leaf grade by deciding grade andlevel equipment 4, errorless through confirming, deciding grade andlevel equipment 4 writes tobacco grower's coding card with data, waits warehouse-in to be transacted system IV to collect data bymain frame 1; Correctly receive data when deciding grade andlevel equipment 4 affirmation transaction warehouse-in system IV, promptly start 5 operations of tobacco leaf conveying equipment the cigarette basket is moved to weigh weighing system III and transaction warehouse-in system IV that deciding grade and level person waits for next cigarette basket arrival deciding grade and level.Be that new family tobacco grower's tobacco purchasing begins when newly being loaded with tobacco grower's coding card in the cigarette basket, deciding grade and level person picks up tobacco grower's coding card once more and reads new tobacco grower's information.

Because this pattern is preliminary examination, deciding grade and level two line parallel work-flows, be provided with between the weighing system III in deciding grade and level system's II and weighing that automatic cigarette basket queuing is crashproof to be provided with 14.

Operating process and pattern one that tobacco leaf enters after weigh weighing system III and the transaction warehouse-in system IV are identical, repeat no more.

Pattern three:

What this pattern cigarette basket coding card adopted is the label coding card, and the previewing system I is still usedpreliminary examination device 3, and deciding grade and level system II is used Card Reader type deciding grade and level equipment, but does not use tobacco grower's coding card, and deciding grade and level equipment only uses the middle distance card reader.

The operation of previewing system I is identical with pattern one.

The operating process of deciding grade and level system II is the comprehensive of pattern one and pattern two, does not have the operating process of tobacco grower's coding card, imports the tobacco leaf grade deciding grade and level person and confirms that errorless back deciding grade andlevel equipment 4 can write cigarette basket coding card with data by the middle distance card reader.

Pattern four:

The important difference of this pattern is that the weighing system III of weighing has comprised packing process, the weighing system III of promptly weighing and transaction warehouse-in system IV be one comprehensive weigh, transaction, packaging and warehousing system.Therefore, the weighing platform of weighing that weighs is the weighing platform of particular design; Increase the deciding grade andlevel equipment 7 of weighing, be used for the deciding grade and level of weighing of packing.

Should be noted that the above instrument is four kinds of mode of operations of the present utility model, but not in order to limit practical range of the present utility model, every by those skilled in the art according to other embodiments that the technical solution of the utility model draws, be the utility model claim scope and cover.
