Description
Technical field
The utility model relates to the wrapping machine for bulk cargo being filled with bag.
Background technology
Prior art has disclosed the wrapping machine such as allowing to be filled to by bulk cargo efficiently in valve bag.These wrapping machine can be the swinging wrapping machine comprising the multiple filling mouth of pipe be distributed on periphery.The wrapping machine with one or more filling mouth of pipe is also open.
Most of valve bag is undertaken filling by totally weighing.This means valve bag, comprise the filling mouth of pipe and the bag seat comprising optional setting that hang with valve bag, weighed by continuous or compartment of terrain in pouring process.The known weight of the signal and bag seat, the filling mouth of pipe and empty bag that carry out self weighing device allows to derive filling product weight.In order to ensure the impact of the filling case that the filling mouth of pipe is not typically provided with, one section of flexible hose is arranged between filling case and the filling mouth of pipe, and the filling mouth of pipe is all arranged with hang together with bag seat and weighting apparatus.This achieve Filling bag not by the impact of wrapping machine remainder, thus make weighting apparatus reliably can determine the observed reading of the product weight poured in bag according to acquisition signal.
Current, people wish that packaging function very accurately controls filling weight.For have such as 50kg demarcation weight bag for, maximum allowable offset be generally significantly less than demarcate weight 1%.
Obtain high filling speed and height filling amount particularity needs to take many measures.In order to ensure the filling speed of economy, bag weight must be determined while the more bulk cargos of feed.The material be filled in weighing process in bag may be adulterated to actual weight.In order to set and regulate the gross weight of expectation better, prior art discloses a kind of pouring process, and it starts with high velocity stream until have such as 90% of the filling weight of expectation in bag.After this, fillingly to continue with low speed flow.Under low speed flow, the amount of the material that time per unit is filled in bag obviously reduces.
Filling speed drops to low speed flow by cutting valve etc. from high velocity stream, and the elastic hose part connecting filling case and the filling mouth of pipe is decreased to such as half cross-sectional plane by its en scissors-like construction when reaching low speed flow limit value by this cutting valve etc.The reduction of flow section can form the difference between high velocity stream and low speed flow effectively.When the target weight has been reached, cutting valve deadend elastic hose part.
Document DE202005011346U1 discloses a kind of for can the dosing mechanism of flowing bulk material, comprises the pinching flexible pipe be made up of rubber elastic material.Pinching flexible pipe is oriented its longitudinal axis and vertically extends, and the outlet at bottom end for making the bulk cargo through dosage flow to pinching flexible pipe from the top entry end of pinching flexible pipe.Pinching flexible pipe is equipped with the squeeze clamper formed by two opposed pinching elements.Both pinching elements all can move to pinching flexible pipe pinching position from pinching flexible pipe release position independently of each other.This system allows to set or regulate different flow sections simply.When only starting in pinching element one, fillingly can such as to be carried out with low speed flow by half flow section.When two pinching elements all move to pinching position, pouring process stops completely.This dosing mechanism can obtain good filling particularity when pinching flexible pipe is vertically arranged.Filling bulk cargo be carried through himself weight to realize, and accelerate described transport by applying vibrations.The shortcoming of this dosing mechanism is that the regulating power of flow section is limited and filling speed is limited, because described filling speed is determined by described own wt substantially.
DE102005039053A1 discloses a kind of method for container filling and a kind of filling machine for implementing the method, wherein the flow section of filling tube reduces, until block when reaching target weight according to the increment of determined container filling weight in pouring process.In order to realize automation, can be equipped with actuating device to filling tube, this filling tube is controlled according to the weight gain of container filling, thus makes the corresponding reduction of the flow section of filling tube.This known wrapping machine is practical substantially, and its shortcoming is that actuating device is that continuous block flow cross section needs more multi-energy.In addition, the amplitude of particularity raising is less.Another problem is that described cross section may be blocked when gap width narrows to the terminal close to pouring process.Filling bulk cargo can form bridge joint, therefore described blocking-up may occur, and this can reduce further the particularity of weight.
Summary of the invention
Therefore, the purpose of this utility model is to provide a kind of wrapping machine, and bulk cargo can be filled with bag in high precision mode by economically.
Favourable specific embodiment of the present utility model is the theme of dependent claims.Other advantage of the present utility model and feature can obtain from describe, in general terms and embodiment describe.
Be used for bulk cargo being filled with bag and comprising at least one filling mouth of pipe according to wrapping machine of the present utility model.At least one delivery element is set, its can be transferred the rotary actuation of device actuating device with by Bulk material to the filling mouth of pipe.At least one control setup is set with at least one weighting apparatus for drawing the observed reading of the bulk cargo amount poured in bag according to the signal of weighting apparatus.This control setup is arranged for the speed of the delivery element controllably changing rotation in pouring process, thus according to carrying out the filling speed of this delivery element of Signal Regulation of self weighing device.
Many advantages are had according to wrapping machine of the present utility model.Be that the delivery element be driven in rotation can realize economical and bag filled with by fast speed bulk cargo according to an important advantage of wrapping machine of the present utility model, especially pour into valve bag.Control setup allows in pouring process, to receive the speed that vacant lot changes the delivery element rotated, correspondingly to affect filling speed.
Unlike the prior art, not that the conveying cross-sectional plane of the filling mouth of pipe changes, but in pouring process, control the adjustment for rotating transport element rotating speed, thus set according to the signal carrying out self weighing device and regulate the filling speed of delivery element best.This allows easily and efficiently to set filling speed, and this allows again also also filling especially accurately especially rapidly then.Control transportation parameters suitably and can realize very that fast speed is filling, the high precision monitor to predetermined filling amount can be realized again.
Delivery element is particularly preferably configured to carry turbine.Conveying turbine can be arranged in filling case, and this filling case to be located near the filling mouth of pipe and can be connected with the filling mouth of pipe by elastic hose portion section alternatively.Conveying turbine can be configured to such as so-called horizontal turbine or vertical turbine.
The speeds control of conveying turbine shows another advantage, and namely in the low speed flow close to pouring process terminal, the pressure putting on filling bulk cargo significantly reduces.But, in the prior art, this conveying turbine runs specifically to demarcate speed always, and this causes the wearing and tearing of bulk cargo significantly can increase in conveying turbine zone in low speed flow runs, because conveying turbine substantially rotates to carry out in original place carrying and do not transfer out suitable bulk cargo amount.The utility model alleviates these phenomenons to a great extent, and this is favourable when sensitive material especially.
All configurations are all arranged to the rotating speed of conveyer actuating device can be regulated at least two grades, thus can form high velocity stream and at least one low speed flow.Particularly preferably be, provide multiple grade and particularly rotating speed can basic continous or infinitely change.The continuous reduction of flow velocity allows to realize very fast and also filling very accurately, thus not only increases filling particularity and controllability, and improves economic benefit equally.
In all configurations, closed head and/or pinching element can be provided with, for closing transport path.Scissors-type closed head can be provided with especially to be used as pinching element to close the transport path formed by elastic hose.Due to according to the utility model, the rotating speed of delivery element is variable, so closed head is after filling terminal or close to can opening transport path during filling terminal completely or closing transport path completely.Close completely and transfer rate can be reduced to zero and stop pouring process.The utility model is without the need to multiple setting or without the need to adopting multiposition cylinder filling to realize high precision.
Another important advantage is that closed head does not need to move to low speed flow position.Mechanical vibration when closed head being transferred to low speed flow position can affect the result of a measurement of weighting apparatus and weight curve can be caused to jump in short-term.In the prior art, due to this reason, need the limit value of low speed flow to turn down, to prevent from temporarily reaching target weight thus make pouring process stop too early mistakenly in jumping.Here it is sets lower by low speed flow limit value thus extends the reason of pouring process.
In all configurations, preferably conveyer actuating device is arranged through to the confession induced current of changer, this changer can export the voltage curve that variable voltage and variable frequency values are shown.That changer particularly can produce interchange and particularly sinusoidal-shaped voltage curve.Adopting this changer to be particularly advantageous, because it provide relatively simple device for providing a large amount of adjustment options, thus accurately can control actuating speed.
Particularly preferably, conveyer actuating device is configured to stepping motor and particularly torque motor.Even if these motors also can produce high rotational force under low-down rotating speed, thus these motors can not only be run at high speed also can run at the low rotational speed.This means especially, and when the terminal close to pouring process, rotating speed can be decreased to rotating speed low substantially as expected continuously or hierarchically from the high rotating speed set for high velocity stream.
Actual speed for implementing pouring process depends on filling amount and depends on the character of filling bulk cargo especially.Especially, in pouring process, bulk cargo sucks suitable large quantity of air by close to the extra pressure caused during pouring process terminal in bag, makes delivery element must overcome this pressure to continue and be fed in bag by bulk cargo efficiently.
In order to produce suitable counter pressure still can send in bag by bulk cargo, delivery element must enough run rapidly.Minimum speed depends on pouring process, especially depends on filling bulk cargo.The utility model allows flexible close to rotating speed during pouring process terminal, and does not need the excessive speeds may destroying product.Excessive speeds can cause carrying the wearing and tearing of turbine and damaged increase in addition.Minimum speed is selected according to instant situation.Minimum speed needs enough high filling to proceed, and needs enough low to allow filling speed become very low and can go to zero especially when the terminal of pouring process simultaneously.
In all configurations, conveyer actuating device can be configured to directly drive gearless inner electric machine.Therefore, the rotor of inner electric machine can be arranged on delivery element axle, and stator can be added in the housing structure of delivery element.This structure makes the structure of filling module or whole wrapping machine compact especially, because motor comprises delivery element and optional filling case can form filling module closely or filling element.
Or can be provided with stepping motor, stepping motor has himself housing and is arranged on housing to be attached to the flange of filling case or delivery element.Also may be provided with flange on filling case or delivery element, be attached on it for gearless electrical machine.This structure also can make filling module have the structure of compact efficient.
In contrast to this, prior art is tended to adopt asynchronous dynamo, and it is run at high speed and is connected with delivery element by band actuating device.This structure needs obvious larger floor area and control ability is low.
Preferably, changer is the constituent elements of control setup.
In all configurations, may with multiple filling element is preferably provided, they be designed to around central rotation axis rotate, wherein filling tube mouth is radially outward arranged.
Advantageously, the rotation axis of conveyer actuating device aligns with the rotation axis of delivery element substantially.The rotation axis particularly driving axis of conveyer actuating device.Delivery element rotating speed is particularly preferably the rotating speed equaling conveyer actuating device.
Special driver element is not needed between conveyer actuating device and relevant delivery element.Such as when conveyer actuating device is the direct driving motor with self housing, described motor can be mounted to the housing of delivery element or filling case.The axle comprising delivery element rotation axis and the axle comprising conveyer actuating device rotation axis are interconnected by traditional swivel joint.Also delivery element directly can be arranged on the axle drive shaft of conveyer actuating device.This forms special compact design, and it can allow the floor space requirements reducing whole wrapping machine.
The rotating speed of delivery element can specific grade or optional grade or the change of basic continous ground.Rotating speed when pouring process terminal especially depends on current instant situation and can become according to the filling bulk cargo of difference, different bag size and different types of bag, and especially described speed can differently be controlled.
Other advantage of optional application form of the present utility model and feature can draw from the description of embodiment, hereinafter with reference to accompanying drawing, described embodiment are discussed.

Each filling module 2 is equipped with switch box 32, and this switch box is vertically arranged in the top of the corresponding filling mouth of pipe 5, and can be a part for filling module 2.Can arrange control setup 13 in switch box 32, this control setup preferably has the changer 23 for direct driving motor 9.Switch box 32 also may be divided into two parts, thus makes switch box 32 part become the parts of filling module 2, and another part of switch box 32 is fixedly attached to the reservoir vessel 34 of wrapping machine 1.Filling module 2 is fixed to from below and is particularly threaded io reservoir vessel 34.
Fig. 2 illustrates the birds-eye view of the wrapping machine 1 with bag seat 20, wherein the filling mouth of pipe 5 radially outward projection of filling module 2.
In order to simple declaration principle, Fig. 3 illustrates the simplification birds-eye view according to wrapping machine 1 of the present utility model, and a filling module 2 is wherein only shown.Each filling module 2 is arranged in a triangular sections 21, and this triangular sections extends angle 29 or covers the angular range of 30 °, thus 12 filling modules 2 altogether can be arranged on the periphery of wrapping machine 1.
In the present embodiment, each filling module 2 includes filling case 7, and bulk cargo 3 is sent to delivery element 8 from filling case, and bulk cargo 3 is poured in valve bag 4 by the filling mouth of pipe 5 by this delivery element.
The reservoir vessel of product in machine intimate or hopper 34 are delivered to filling case 7 from top.Reservoir vessel 34 transfers from unshowned product hopper, to receive product as required, and this product hopper is arranged on above wrapping machine.
Although filling case 7 can hold the filling bulk cargo 3 of a certain amount of institute for centre supply, filling case 7 also substantially only may be used as inlet point or the housing of delivery element 8.
In the present embodiment, delivery element 8 rotates around horizontal axis and is provided with the conveying turbine 14 of turbine blade 38 (see Fig. 6 a and 6b), this conveying turbine is arranged to rotate, to be transported in the filling mouth of pipe 5 by bulk cargo 3 around the current rotation axis 11 for level.
The vertical transport turbine 14 with its horizontal axis of rotation 11 is driven by the conveyer actuating device 9 being designed to direct driving motor, and this conveyer actuating device is the assembly of filling module 2 equally.In order to reduce particularly to be used in floor area needed for the filling module 2 on swinging wrapping machine 1, direct driving motor 9 aligns with the horizontal axis of rotation 11 of delivery element 8 and is connected to filling case 7 side with flange, and simultaneously the filling mouth of pipe 5 is arranged on 15 above.Or filling case 7 can be designed to allow the component of direct driving motor 9 to insert.This means, when being installed in a predefined manner in swinging wrapping machine 1, conveyer electric driver 9 is arranged in filling case 7 or conveying turbine 14, and the filling mouth of pipe 5 is radially outward arranged simultaneously.
This design and arrange tolerable injury level arrange conveyer electric driver 9 be very economical space saving contained in the circumference of swinging wrapping machine 1.Due in this triangular sections 21, the floor area that can arrange increases with radius and increases, and the size therefore making direct driving motor 9 adapt to the filling mouth of pipe 5 and wrapping machine 1 is particular importance.
When the filling mouth of pipe 5 of equal number, this example allows diameter to reduce 20% to about 2.4m from about 3m, thus the volume significantly reduced in wrapping machine 1 place of erection shown in broken lines in figure 3 and required floor area 12.Required floor area 12 in plane reduces more than 1/3rd.The diameter reduced reduce further traffic cost when transporting machine, because common truck is generally just enough to for transport.
In the present embodiment, the system that automatically inserts 27 as schematically in fig. 3 the filling mouth of pipe 5 rotate past automatically insert system 27 while valve bag 4 is inserted on the filling mouth of pipe 5.External diameter significantly reduces about 20% also makes the circular velocity of the filling mouth of pipe 5 reduce about 20%.This makes slash pocket system 27 can obtain higher slash pocket volume amount at the rotating speed of wrapping machine 1 further with when exporting identical.
Around axis 25 rotate during, valve bag 4 is filling, thus these valve bags are filled when carrier band 28 is unloaded in arrival, valve bag unload carrier band place can be unloaded.Present bag seat 20 is activated to be unloaded from the filling mouth of pipe 5 by valve bag 4, and is thrown into and unloads on carrier band 28.Then can the weight of test valve pocket 4.
Wrapping machine drive motor 31 is by rotating band 36 rotary actuation wrapping machine 1.
Fig. 6 a and 6b illustrates the rough schematic view particularly as the functional cohesion between the conveyer actuating device 9 of electric direct-drive motor and delivery element 8 or vertical transport turbine 14 respectively.
Fig. 6 a considers that direct driving motor 9 comprises axle drive shaft 39, and this axle drive shaft (by not having markd swivel joint) is linked with the driven shaft 35 of turbine blade 38 or delivery element 8.The horizontal axis of rotation 11 of conveying turbine 14 correspondingly aligns with electrical axis 10, thus overlaps with this electrical axis.Because direct driving motor 9 is preferably designed to flange-type motor for this attachment, so conveying turbine 14 or filling case 7 are also shown with attachment flange.Filling case 7 dimensionally with the flange (mark) of torque motor or direct driving motor 9 mutually mates and comprises the hole be distributed on the whole periphery of flange, and this hole is used for detouchable component such as screw, nut and setting up piece.
If direct driving motor 9 is electronic, so it is preferably so-called torque motor, and the stator coil of this torque motor is powered by the rotary current with different frequency and voltage.The corresponding motor 9 being active conveying turbine 7 by changer generates signal.The body of the magnetic forever – that the rotor of direct driving motor 9 tends to particularly be sintered into by the material that can produce highfield energy density by the body of the magnetic forever – be distributed on its periphery is formed, thus makes rotor no longer need to provide power supply by the component be easily disturbed such as current colector.
For the reason driving stability, may need to obtain rotor angle.This can realize non-contactly.Direct driving motor effect is controlled fine, because the filling cycle of itself and wrapping machine 1 matches by the sinusoidal pattern voltage with different magnitude of voltage and different frequency.Voltage and frequency are controlled to the active transducer of the corresponding control unit 23 of filling module component by configuration.This allows the independent rotating speed controlling active conveying turbine 14, thus by controlling rotating speed, filling stream is divided into high velocity stream and low speed flow.
Formed by motor connectors 37 or connection box for the voltage connector of stator coil and the data connector for obtaining rotor angle.Electric wire leads to control setup 13.
Fig. 6 b considers that the housing of conveying turbine 14 is specifically designed to the installing space formed for the component of in-built direct driving motor.Need for carrying the axle drive shaft 39 of the turbine blade 38 of turbine 14 extend and be correspondingly supported.The stator of inner electric machine can load the housing correspondingly increased of such as press-in conveying turbine 14, and the axle 39 extended receives the rotor part of such as contracting cover or the direct driving motor that particularly removably connects.
Inner electric machine is used to allow to utilize required floor area better further.Wrapping machine 1 can be arranged to the further optimization of its overall dimensions.This is particularly suitable when using single motor component such as rotor, stator etc.
The control principle of in-built direct driving motor is substantially identical with flange-type direct driving motor.
Fig. 4 to Fig. 6 illustrates the embodiment of filling element 30 with different views.Although the filling element 30 shown in figure 4 – 6 does not have bag seat, it can be equipped with bag seat alternatively.
Fig. 4 illustrates the sectional view of filling module 2.Other component of filling module 2 is directly or indirectly attached to support portion section 56 and filling case 7.When installing filling module 2, filling case 7 is connected to reservoir vessel or the hopper 34 of wrapping machine 1 from below.
The filling mouth of pipe 5 to be arranged on before filling module 2 15, and conveyer electric driver 9 is arranged on side, and conveyer electric driver is flange-type direct driving motor or the direct driving motor 9 as in-built component.
The filling mouth of pipe 5 is equipped with marsupial seat 33, and this bag of seat has test function to determine whether valve bag 4 hangs on the filling mouth of pipe 5 before filling begins.Only detect bag, pouring process just can start.
As especially found out from the view of Fig. 4, bulk cargo 3 is fed to the filling mouth of pipe 5 by vertical transport turbine 14 from filling case 7.Vertical transport turbine 14 can rotate around the rotation axis 11 perpendicular to drawing.Conveyer electric driver 9, special in it is flange-type direct driving motor 9, there is the rotation axis 10 of orientation in the same manner.
Referring now to Fig. 5, it illustrates the opposite side view of filling element 30.In order to clear, pouring process is shown, valve bag 4 is positioned at the filling mouth of pipe 5 place as shown in the figure and fills with bulk cargo 3.Fig. 5 illustrates closed head 22 or its driving cylinder, and its allows to reduce the flow velocity through the filling mouth of pipe 5 by the correspondingly filling passage of constriction.When can not free-pouring specific products, this closed head 22 can be removed and by control conveying turbine rotating speed to control product stream.This allows to save filling valve 22 and driving cylinder thereof.For the bulk cargo 3 of flowing fast, recommend to arrange filling valve 22 to guarantee that safety is closed.
Weighting apparatus 19 measures the filling mouth of pipe 5 and valve bag 4 in pouring process, and the weight of filling bulk cargo 3 releases according to the known weight of the filling mouth of pipe 5 and pouring process controls according to gained weight.
Fig. 7 illustrates the simplification view of the cross-sectional plane of the filling case 7 of filling module 2.At least one receiver hole 58 is formed in the bottom of the housing 57 of filling case 7.Receiver hole 58 horizontal location and with conveying turbine 14 rotation axis 11 almost parallel.Filling case 7 has at least one in the wall of housing 57, perpendicular to the air extractor vent 59 of receiver hole 58.Air extractor vent 59 extends in the conveyor chamber 60 of delivery element 8, and air extractor vent angularly opens wide at this conveyor chamber place, thus makes the air-flow in introducing air extractor vent 59 help conveying bulk cargo 3.
Drafting apparatus 61 is furnished with, for directed air being delivered to the conveying turbine 14 controlled by control setup 13 in receiver hole 58.Ventilation in conveyor chamber 60 lower zone decreases the friction of bulk cargo 3 and housing 57 wall, thus can produce the filling of low friction and low wearing and tearing.
In the switch box 32 being attached to filling module 2, be furnished with control setup 13, this control setup also can comprise the changer for direct driving motor 9.
Conveying turbine 14 is configured to rotate around horizontal axis, and wherein turbine blade 38 is supported for and rotates around horizontal axis of rotation 11.
The floor area required for packaging system 1 illustrated obviously reduces and filling element 2 can removably be attached on it, thus saves manufacture and traffic cost and reduce maintenance cost.
See Fig. 8 and Fig. 9, exemplarily pouring process will be discussed now.Fig. 8 illustrates the time dependent weight curve 47 of bag 4 in pouring process.Weight curve 47 is shown in Figure 8 for solid line.Fig. 8 also illustrates the time dependent speed curves 48 of conveying turbine 14 further.Weight curve is with reference to the y-axis on the right, and speed curves 48 is depicted as the dotted line with reference to left side y-axis.
In an illustrated embodiment, the moment 40 of speed after start-up soon within the scope of 0.2 to 0.3 second of turbine 14 is carried to reach the command speed of given 700 revs/min (rpm).
Weight curve 47 illustrates that weight is constant in time and intimately to increase point-blank.When carrying turbine 14 to rotate with given command speed, pouring process carries out with high velocity stream 49.
From the moment 40, the rotating speed 18 of conveying turbine 14 keeps the command speed of current 700rpm, until the weight curve 47 being filled to the bulk cargo 3 in bag 4 reaches threshold value 51, this threshold value is such as 45kg, and target bag is heavily 50kg.Although described threshold value 51 is 90% of filling weight, threshold value 51 Ke Yi – according to different – of filling bulk cargo be such as 70%, 80%, 85% or 95% of filling weight.For the filling amount that other is given, threshold value 51 can be set as other percentum or absolute value.
When the moment 41, place reached threshold value 51, the speed 18 of conveying turbine 14 reduces continuously with Filling bag 4 as quickly as possible in the illustrated embodiment, simultaneously with the filling weight of high particularity monitoring expection.
First speed 18 in low speed flow 50 scope be close to and decline point-blank, until described in moment 42 place weight and predetermined final weight only poor about 2%.Can such as 98% or 49kg place setting threshold 52, now transfer rate still reduces such as to make the current specific final weight for 50kg of weight curve 47 asymptotic expansion further.
In fact, the time dependent curved path of speed 48 is close to there being two flex points during pouring process terminal.First flex point the moment 41 place occur soon after reaching first threshold 51, second flex point greatly about the moment 42 place occur, from this moment speed with easy curve close to final velocity 46.
For the filling bulk cargo 3 of most of institute, speed 46 is obviously greater than zero, because air will enter in bag 4 with filling bulk cargo 3 in pouring process.Any air of bag contained by 4 all forms extra pressure by bag 4, and conveying turbine 14 also must resist this extra pressure to continue bulk cargo 3 to be fed in bag 4 except resisting the counter pressure of bulk cargo.In bag 4, the size of internal pressure depends on filling bulk cargo 3 and its quality and experience.Such as, the mode of movement of bulk cargo 3 significantly will affect air content.With conveying turbine transferring bulk cargo time, the air content sucked in bag will from different during screw transferring bulk cargo.The mode of fluidisation bulk cargo also can determine the air content in bulk cargo 3.Air content also depends on that bulk cargo 3 was placed on the time length in hopper before pouring process.The bulk cargo of firm filling feeder hopper has higher air content.
The method of current proposition can regulate final velocity 46 automatically to guarantee slowly to process filling bulk cargo 3.Carry the unnecessary high speed of turbine 14 to be avoided in low speed flow 50, can guarantee efficiently filling for bag 4 on the other hand to predetermined gross weight simultaneously.
Can robot control system(RCS) be formed by weight curve 47 control rate 18, wherein pouring process terminal moment 43 place speed 46 approximate greatly required minimum velocity 46, under this minimum velocity, still can resist instant bag internal pressure and bulk cargo be filled in bag 4.
Meanwhile, in whole pouring process, the constant speed 18 being in a high position ensure that special filling rapidly, thus ensure that the filling of economy.
Starting in the short time after pouring process, at moment 40 place, be now after about 0.2 or 0.3 second, reached given command speed, this command speed is preferably held constant at speed 45 during high velocity stream 49.
Fig. 9 shows the enlarged view being converted into low speed flow 50 from high velocity stream 49 according to Fig. 8.During high velocity stream 49, the interrelation of weight and time is almost straight line.In high velocity stream scope 49, the gradient in grade ratio low speed flow 50 scope is much precipitous.Near the destination county of low speed flow scope 50, the weight of the filling bulk cargo 3 of institute substantially asymptotic expansion is extremely the predetermined final weight of 50 kilograms here.The utility model allows very economical and very accurately bulk cargo 3 is filled with bag 4.Control the speed 18 of conveyer actuating device 9 and the speed thus controlling delivery element 8 allows to realize simultaneously again more accurate dosage faster than prior art by relatively simple device.Without the need to changing filling cross-sectional plane.
This control can such as realize by direct driving motor or torque motor.Assessment carrys out the signal 26 of self weighing device 19 and converts the quality of the bulk cargo be filled in bag to, can provide one flexible especially and accurate method.
Also can set filling curve and be obtained the weight curve of curvilinear motion in time by continuous or compartment of terrain comparison object value and actual value, and readjusting motor speed and meet given filling curve to make actual weight curve.Except bulk cargo is filled in valve bag, bulk cargo is filled in Openmouthed bag be especially possible with preferably.Being filled to by pasty product is also possible in bag.
