Electrostatic adsorption device is carried on pressing plate, reinforces anti-adsorption effect using the adsorption capacity of electrostatic.It can also be by expanding pressing plate and page
The mode of face contact area reinforces anti-adsorption effect, e.g., can add a riser in the side that pressing plate is in contact with the page, to expand pressure
The contact area of plate and the page.
Workbench is mounted on the top of rack, and slideway and storage box are mounted on behind scanning area.
The course of work of the device
As shown in figure 12, a pile answer volume is placed on answer volume rest area, then system starts, and PLC control system starts
Work, first absorption mobile mechanism are started to work, and as shown in figure 13, the effect for adsorbing mobile mechanism is that answer volume is picked up and moved
Clip position is moved, the reversion of motor one is moved by adsorbing mobile belt wheel, absorption moving conveyor belt drive suction cup carrier along absorption
Sliding rail to the left (not being absolute position for figure) move to reach designated position (one pile answer confers titles of nobility on the upper of glue side
Side).Sensor one detects that backward PLC control system issues signal PLC control system control motor in place for absorption mobile mechanism
One stop, solenoid valve one (three position four-way directional control valve) forward conduction, at this time pneumatic cylinder one and pneumatic cylinder two push respectively sucker to
Lower pressure sensor of the movement when sucker pushes down answer volume on sucker sends a signal to PLC control system, and solenoid valve two (two
Three-way diverter valve) it is connected, sucker sucks the side that glue is conferred titles of nobility in answer, and PLC control system control controls one reverse-conducting of solenoid valve,
Pneumatic cylinder drives sucker to lift answer volume, and then solenoid valve one returns to normality position, and pneumatic cylinder stops.The rotating forward of motor one passes through absorption
Mobile belt wheel absorption moving conveyor belt drives suction cup carrier to move right along absorption shifting sledge, and answer volume is moved quickly into folder
Position is held, solenoid valve two is closed, and sucker decontrols answer volume.
As shown in figure 14, when sensor two detects that absorption mobile mechanism reaches clip position, PLC control is sent a signal to
System, PLC control system controls motor one and stops, while motor two starts, and clamp moving mechanism is started to work, and clamping moves at this time
The effect of motivation structure is the hard-edge for clamping answer volume and mobile answer volume to scanning area, and motor two is rotated forward through clamping movement band
Clamp moving mechanism is moved to clip position by wheel, clamping moving conveyor belt, and sensor two detects that clamp moving mechanism reaches
After clip position, PLC control system is signaled to, PLC control system controls motor two and stops, three forward conduction of solenoid valve, gas
Cylinder pressure three pushes pneumatic clamps to clamp answer volume, and motor two inverts, by clamping mobile belt wheel, clamping moving conveyor belt and pneumatic clamps
Answer volume is moved to scanning area, at this time in the underface of sucker beyond the page turning of answer volume.Sensor three detects folder
After holding mobile mechanism in place, PLC control system is signaled to, PLC controls camera and scans cover, while adsorbing mobile mechanism again
Task, the effect for adsorbing mobile mechanism at this time is to pick up cover, and PLC controls one forward conduction of solenoid valve, and pneumatic cylinder one is gentle
Cylinder pressure two drives sucker to move downward pressure sensor after sucker pushes down answer volume and signals to PLC control system, solenoid valve two
Conducting, sucker suck cover, and PLC control system controls one reverse-conducting of solenoid valve, and pneumatic cylinder counter motion starts cover, simultaneously
PLC controls the electromagnet power-off in preventing suction again mechanism one, and electromagnet is separated with iron plate, and spring band movable pendulum arm rotation, pressing plate pushes
Touching answer volume prevents adhesion, is then electrified to pressing plate reset, and page turning smoothes out mechanism and starts to work, when floating frame reaches below sucker
Solenoid valve two closes sucker and unclamps cover, and the reversion of motor three drives page turning to smooth out mechanism edge by page turning belt wheel, page turning conveyer belt
Page turning guide rail it is mobile, open the cover of answer volume completely.The electromagnet of preventing suction again mechanism two powers off, and pressing plate compression is just twisted over
Cover, the reversion of motor three drives page turning floating mechanism to be moved to the left along page turning sliding rail by page turning belt wheel, page turning conveyer belt,
Page turning smoothes out mechanism and returns to initial position.After sensor four detects that page turning smoothes out mechanism, PLC control system is sent a signal to,
PLC control camera starts to scan first page.After the completion of scanning, the pneumatic cylinder one, two adsorbed in mobile mechanism pushes sucker to inhale
First page paper is played, while the electromagnet power-off in PLC control preventing suction again mechanism one, electromagnet are separated with iron plate, spring band movable pendulum
Arm rotation, pressing plate, which pushes touching answer volume, prevents adhesion, is then electrified to pressing plate reset, and page turning smoothes out mechanism and starts to work, and smoothes out
Frame reaches solenoid valve two when below sucker and closes sucker release first page, and the reversion of motor three passes through page turning belt wheel, page turning conveyer belt
It drives page turning to smooth out mechanism to move along page turning guide rail, opens the first page of answer volume completely.The electromagnet of preventing suction again mechanism two
Power-off, pressing plate compress the first page just twisted over, and the reversion of motor three drives page turning trowelling machine by page turning belt wheel, page turning conveyer belt
Structure is moved to the left along page turning sliding rail, and page turning smoothes out mechanism and returns to initial position.So circulation, after the completion of a scanning, PLC
Control motor three rotates clamp moving mechanism and moves right along clamping shifting sledge, and answer volume is moved in inclined ramp,
After sensor five detects clamp moving mechanism in place at this time, PLC control system is sent a signal to, it is anti-that PLC controls solenoid valve three
Guide ventilation cylinder pressure three drives pneumatic clamps to unclamp, and answer volume is fallen into storage box along slideway downslide.Computer after the completion of scanning
The curriculum information of first page, class's information are extracted using image recognition technology, generate a file；Known using image
Other technology extracts the examinee information of first page, and document is named with examinee's name student number, while depositing in use
In curriculum information and the file of class's information name, the picture extracted is converted into PDF document preservation.It not only can save
Save archives storage space, and answer volume transfer consult it is also very convenient.
