Technical field
The present invention relates to the packing conveyor skill of the product such as pellet and powder of the industry such as chemical industry, chemical fertilizer, medicine, metallurgy
Art field, more particularly, to a kind of big bag conveying forward method and conveying transfer.
Background technology
The product packagings such as the pellet and powder of the industries such as chemical industry, chemical fertilizer, medicine, metallurgy generally include the pack of material, claim
The multiple working procedures such as weight, sealing, detection, piling, complete per procedure in different workshop sections, pack from a workshop section to next work
The conveying of section is completed by supporting packaging conveying system.At present packaging quantitative values are referred to as big bag more than 2 tons, defeated
During sending, according to production requirement, conveying direction often sends change, therefore, it is defeated that bag induction system must design packaging
Send forward method and the conveying transfer adaptable with it.Conveying transfer can directly affect production efficiency and packaging is quantitative
Value.
At present big bag conveys forward method:Big bag enters conveying transition region from main channel, and conveying transition region has some
Root carrying roller, carrying roller is multidiameter, and two ends are rack-mount by bearing, can be around axis rotation.Each carrying roller is fitted with
Link chain mechanism, sprocket wheel is fixedly connected with carrying roller, and chain is driven with sprocket engagement, so in the case where motor and reductor drive, passes through
Link chain mechanism, each carrying roller is with certain rotational speed, and the conveying for big bag provides power, and big bag is placed on carrying roller,
As the rotation of carrying roller, big bag are moved forward, bag is transported to into steering platform edges;Turn to stage+module carrier bar conveying
Device, big bag can be moved with above-mentioned carrier bar mode of movement on carrier bar, bag be moved to into steering from conveying transition region flat
On platform;Chain plate conveyer is arranged on platform floor, and driving means rotate base plate, rotates whole chain plate conveyer,
So as to the conveying for realizing big bag is turned to.
Corresponding big bag delivery platform transfer mainly includes roller-type transfer unit, chain-plate type transfer unit
With machine driving turning member, wherein either chain-plate type conveying or roller-type conveying, its transmission mechanism is all chain drive,
In big bag conveying steering procedure, chain continuously works under the conditions of heavy duty, impact shock, conveys unstable, generation noise,
The easy wear out failure of chain;Machine driving turning member is by motor, decelerator, gear drive and supports part to constitute, by
It is fixed than transmission in part, forward direction turns round, inefficiency identical with reverse opening speed;The big built-in material of bag is pellet
Or powder, it is anisotropic material, in conveying steering procedure, the motion of material is all non-homogeneous Bed Load Movement, specifically

The clamping plate 13 is V-type clamping plate, and its cornerite is 150 °.
A kind of big bag conveying forward method of employing said apparatus, step is as follows:
1) big bag 27 is clamped with clamping device;
2) big bag 27 is moved through into 28 to the platform 29 of transition region I from main channel edge 26 along guide rail with actuator;
3) with revolving dial device the delivery platform for holding big bag 27 is turned round according to the conveying direction that production line is required
Certain angle;
4) big bag 27 is moved through into 32 to the subchannel 31 of transition region II from platform 29 along guide rail with actuator;
5) clamping device unloading, big bag 27 is placed on subchannel 31;
6) apparatus platform reversed turning is to initial position.
The big bag 27 of described below is diameter 800mm, high 1400mm, 2 tons of quality, and the material of big bag 27 is that PTA is (large
Organic Ingredients).
As shown in figure 4, Wrap angle of clamping plate is 180 ° can be seen that in the starting stage, the big bag 27 of material is in the pressure of clamping plate 13
In the presence of deform, clamping plate 13 apply pressure reach it is certain after, the deformation drag of big bag 27 increase, deformation is slow, now, greatly
Material is gradually compacted in bag 27, and final clamping plate 13 is fitted with big bag 27, and the deformation values of big bag 27 tend to constant.This is turned out
Compressed by clamping device clamping plate 13, material can be compacted in big bag 27, it is ensured that big bag 27 big bag at the volley
No longer it is the compound movement of the various ways of the slip, rolling or saltation of conventional apparatus between 27 internal particles, but it is relatively quiet
Only, big bag 27 is conveyed steadily, and inertia force is little, and the varying stress load that actuator and revolving dial device are born subtracts significantly
It is few.
Bag internal pressure distribution situation as shown in Figure 5, material is PTA, unit clamping plate pressure is respectively 6,8,
10MPa, applies 6MPa unit clamping plate pressure, and the internal stress of big bag 27 is 0.5MPa, and the stress can not be compacted material, at this
In the case of kind, when big bag 27 is moved with certain speed, the motion state of its materials inside particle is still complicated, particle inside bag
The compound movement of the various ways of slip, rolling or saltation is included, when applying 8,10MPa unit clamping plate pressure, inside big bag 27
Stress reaches 1.5Mpa, is compacted material, and now the motion state of material becomes simple, material particles geo-stationary, big bag
27 stable movements of bag.It can be seen that clamping device unit clamping plate pressure optimum value is 8MPa.
As shown in Figures 6 and 7 be impact figures of the Wrap angle of clamping plate α to bag internal pressure, when the cornerite of clamping plate 13 be respectively 180 °,
150 °, 120 ° when, big bag 27 diverse location measure the elastic deformation amount's result of clamping plate 13, can analyze from figure, 180 °
Cornerite clamping plate differs 9.50mm, deflection maximum 9.79mm, deflection mean value 5.14mm in different bag positions deflection;
150 ° of cornerite clamping plates differ 4.30mm, deflection maximum 7.70mm, deflection mean value in different bag positions deflection
3.60mm;120 ° of cornerite clamping plates differ 4.94mm in different bag positions deflection, and deflection maximum 9.00mm, deflection are put down
Average 6.46mm.Analysis above is reached a conclusion:150 ° of cornerite clamping plate deflection differences, deflection maximum and deflection mean values
It is all minimum, so the present invention adopts 150 ° of cornerite clamping plates.
The present invention as described in Figure 8 implements the defeated route of bag, one, big bag 27 reach station I from main channel, station I exists
Main channel 26 and the intersection of transition region I 28;2nd, by actuator, big bag 27 reaches station II from station I, and station II exists
On the delivery platform of transition region I 28;3rd, delivery platform is turned to, and big bag 27 reaches station III from station II;4th, lead to again
Actuator is crossed, bag reaches station IV from station III, and station IV is in subchannel 31 and the intersection of transition region II 32, subchannel 31
Lead to purpose workshop section I;The big route of bag 27 diagram of the above I~IV is represented with solid line, whole to turn to conveying in this course of conveying
Device load.After big bag 27 is transported to station IV, turning transporting device unloading.Subsequently, device dotted line institute as illustrated
Show, along IV~I route, be returned to station I, in the process, whole turning transporting device is unloaded.In conveying transfer unloading
While, big bag 27 is transported to purpose workshop section I 30 by subchannel 31.Similarly, by conveying transfer, big bag 27
Other purpose workshop sections can be reached.
Invention device working cycles as shown in Figure 9, present invention conveying transfer major function motion includes following several
Individual action:Support 19 is movable, clamping plate 13 close up open, platform 29 is turned round.
The present invention obtains the movable speed of support 19 by adjustment hydraulic cylinder 23, is realized by adjusting hydraulic cylinder 25
