Description
Technical field
The present invention relates to metallurgy industry online weighing technical fields, and in particular to automatic on a kind of continuous casting and rolling production line line
Weigh device.
Background technique
Continuous casting and rolling production line in metallurgical industry, workpiece transmit on roller platform from coiling, compacting, packing and plastic packaging
And complete corresponding procedures.Finished product could be used as by also needing to stamp yoke after being packed.Then finished product by Forklift Worker's scraper from
Roller platform is opened, weighing of weighing is transported on electronic platform scale, together with the weight including yoke as final product weight, for subsequent
Report and submit client and calculate freight etc..By fork truck by finished product scraper to warehouse for finished product after weighing.Due to production line every 8 minutes or so
A product is just produced, causes fork truck after completing a workpiece weighing, in-orbit platform where rites are performed is needed nearby to wait for a period of time.Until
Warehouse for finished product is weighed and be transported to finished product after the completion of new finished product on timely scraper roller platform, is ensured on track platform without congestion.
Fork truck leaves during roller platform weighs and enter warehouse for finished product with scraper product in scraper finished product, and fork angle is inserted and retreated before needing 4 times and 2 times
It lifts and decentralization acts, and because fork truck is diesel vehicle, exhaust emissions is big, and finished product weighs 4 tons.To 4 tons of heavy finished products into
Row frequently lifts and lowering operation, causes a large amount of fuel consumption and exhaust emissions, causes workshop air muddy, oil consumption occupies high
Under not.And fork truck worker needs to wait for a period of time in product line end, causes the waste of manual resource.The thus company of needing to improve
The process of weighing of weighing of continuous rolling production line is cast, on-line automatic weighing of weighing is carried out.
China Patent No. CN105170930A, publication date on December 23rd, 2015, a kind of online weighing roller-way, including conveying
Roller-way is uniformly provided with multiple rollers on rollgang, one or more pairs of shear force sensors, multiple shearings is equipped on rollgang
Sensor forms measurement zone；Workpiece to be weighed passes through the measurement zone under the rotary action of roller-way.By using in conveying roller
The weighing structure that shear force sensor is installed on road, under the premise of rollgang is not truncated and is not necessarily to increase foundation of civil work
It is installed, does not influence normally to produce and process, installation improvement cost is low；When installation only need to the side of rollgang simply
One or more pairs of shear force sensors are installed, online weighing, simple installation can be realized；It is theoretically defeated it is not necessary that rollgang is truncated
Send roller-way that can infinitely extend, and measurement zone can according to need any place being arranged on rollgang, can satisfy not
With the demand of operating condition.But its shear force sensor needs to bear biggish stress, dynamic loading and shock loading, to the intensity of sensor
It is very high with performance requirement, cause its sensor cost of installation and maintenance high, and it weighs under workpiece motion s state, institute
The weight accuracy of weighing is not high.

Set, pound front limit switch 5, pound rear limit switch 7 and roller platform tail limit switch 9 be arranged in electronic platform scale before, after electronic platform scale
With roller platform tail end, position sensor 8, pound front limit switch 5, pound rear limit switch 7 and roller platform tail limit switch 9 with control
Device electrical connection processed.
When position sensor 8 detects that workpiece 1 reaches before electronic platform scale 6, controller control roller platform 2 stops operating, and
It controls hydraulic carrying implement 3 and is transported to workpiece 1 on electronic platform scale 6 from roller platform 2, then control hydraulic carrying implement 3 and be detached from workpiece 1,
Controller detection electronic platform scale 6 shows weight, and after electronic platform scale 6 shows again stable, record electronic platform scale 6 shows recast for 1 final weight of workpiece note
Record, then controller controls hydraulic carrying implement 3 and carries workpiece 1 again, and workpiece 1 is transported to subsequent roller platform 2 from electronic platform scale 6
On, controller control roller platform 2 rotates again, workpiece 1 is transported backward, when position sensor 8 detects that workpiece 1 reaches roller-way
When 2 tail portion of platform, controller control roller platform 2 stops operating, and notifies fork truck by work by the combined aural and visual alarm that controller connects
Part 1 is carried to warehouse for finished product.1 position of workpiece can be controlled for controller by limit switch and more reliable guarantee is provided, when workpiece 1
When before arrival electronic platform scale 6, not only location of workpiece judgement can be carried out according to position sensor 8 by controller, pound can also be passed through
Front limit switch 5 further determines that the specific location of workpiece 1, and pound rear limit switch 7 will be triggered when workpiece 1 leaves electronic platform scale 6,
It enables the controller to ensure that workpiece 1 has been moved off electronic platform scale 6, when roller platform tail limit switch 9 is triggered, controller will be bright
True judgement workpiece 1 will be disengaged from roller platform 2, to stop the rotation of roller platform 2 immediately.
It is illustrated in figure 2 hydraulic carrying implement structure chart, be illustrated in figure 3 hydraulic carrying implement and carries track side view, liquid

On frame 11, fork angle telescope motor drives fork angle 10 to stretch out or retract, track mobile motor, hydraulic lifting post 12 by transmission mechanism
It is electrically connected with the controller with fork angle telescope motor.4 single track cross section of track is carried into I-shaped, hydraulic 3 bottom bay of carrying implement
13 groove two sides are fixed with driven wheel 16, and 16 upper limb of driven wheel, which is connected to, carries 4 single track two sides flange bottom surface of track.
After controller, which controls hydraulic carrying implement 3, is moved to 1 position of workpiece, the decline setting of hydraulic lifting post 12 is high
Degree, then control fork angle 10 forward extends out, and 1 lower section of insertion workpiece, then hydraulic lifting post 12 rises, and workpiece 1 is driven to be detached from roller
Platform where rites are performed 2, after hydraulic lifting post 12 increases set distance, controller controls the work of track mobile motor, passes through track movable pulley
15 band hydrodynamic pressure carrying implements 3 and workpiece 1 are moved along track 4 is carried, when position sensor 8 detects that hydraulic carrying implement 3 is moved to
When the position of electronic platform scale 6, track mobile motor stops working, and then hydraulic lifting post 12 slowly declines, and workpiece 1 will gradually be fallen in
The active force become larger is generated on electronic platform scale 6 and to electronic platform scale 6, after pitching disengaging workpiece 1 of angle 10, electronic platform scale 6 shows to become again
In stabilization, electronic platform scale 6 after stablizing shows that the final weight that recast is workpiece 1 records, and then hydraulic lifting post 12 increases, again
After lifting workpiece 1, the position of subsequent roller platform 2 is moved to along carrying track 4 by track mobile motor, under hydraulic lifting post 12
Drop, workpiece 1 is slowly placed on roller platform 2, then hydraulic carrying implement 3 returns to the position of beginning.
