Sizing material cut-to-length device and method in production process.
Background technology
The automatization of rubber tyre equipment, unmanned be the developing direction of current rubber tyre equipment.Wherein in tire production from
The problem that dynamicization have to solve is exactly the accurate fixed-length severing of sizing material.
Existing sizing methods mainly has two kinds: the first, from the beginning of zero point (severing position), by servomotor or variable-frequency electric
Machine drives conveyer belt to be fed forward sizing material, drives detection sizing material displacement by encoder and motor simultaneously, when detecting distance with
Stopping conveying when preseting length is consistent and realize fixed length, there is mechanical transmission errors in this kind of method, the scope simultaneously measured is that sizing material is complete
Long, deviation is bigger；The second, conveyer belt is driven to be fed forward sizing material by servomotor or frequency conversion motor, from detection reference point (inspection
Slowdown monitoring switch detection position) start, drive detection sizing material to move forward distance as detected value by encoder and motor, will detection
It is worth and is added as fixed length foundation, when detected value and initial value sum and preseting length with initial value (cut-off knife and detection switching space)
Stop conveying time consistent and realize fixed length, although this kind of method reduces detection range, but equally exist mechanical transmission errors, and
There is also the delayed detection error caused of system feedback.
The technology that existing Fixed Length Test uses all uses open-loop control method, by switch detection or default initial
Value, as examination criteria, and by the feedback of drive system output and encoder as reference, calculates the length of sizing material conveying,
In this, as the foundation of cut-to-length, the problem that this method exists is that system is in open loop, it is impossible to detect because of machine driving and
The error that system feedback deviation causes, after causing severing, sizing material error in length is excessive, it is impossible to meets and uses requirement.

Therefore, this system is applicable to the sizing material of the various length of severing.
Sizing material cut-to-length method:
According to the length of the sizing material needing severing, set benchmark zero point and the position of image center, fixing cutting device and camera lens
The position of head；
Sizing material is placed on conveyer device, starts conveyer device, and sizing material is carried to the direction of image center by benchmark zero point；
If the detection range of pick-up lens is " L ", sizing material enters the detection range of pick-up lens to start, pick-up lens startup work,
The picture of shooting is delivered to controller；
The picture that controller analysis receives, calculates the alternate position spike between position and the image center 7 of sizing material stub bar, then sizing material material
Distance between head and benchmark 0. 6；
When alternate position spike between the position and image center of sizing material stub bar is zero, start shearing device, sizing material is cut off.
The invention has the beneficial effects as follows:
The present invention detects, by pick-up lens, the position that sizing material head is fed forward in real time, will actual measurement sizing material head position and reference zero
The distance of point is as the detected value of sizing material fixed length error, and is controlled the conveying mechanism adjustment conveying speed of sizing material by image acquisition data
It is consistent with preseting length that degree and stop position realize detected value, it is achieved accurate fixed-length, relative to traditional open-loop control method, no
Need to rely on switch block and mechanical part detection sizing material length, overcome system mechanics transmission deviation delayed with system control feedback
The fixed length error caused.

Detailed description of the invention
Below in conjunction with accompanying drawing, the detailed description of the invention of the present invention is further detailed.
As shown in Figure 1 to Figure 3, sizing material cut-to-length system, including conveyer device 5, cutting device 2, also bag image collector
Put and controller.
Conveyer device 5 is connected to servomotor or frequency conversion motor, as the dynamical system of conveyer device, controls whether conveyer device is held
Row conveying action.Conveying direction along conveyer device is provided with benchmark 0. 6 and image center 7, benchmark 0. 6 and image
Central point 7 is as two position reference points, and distance therebetween is equal to the sizing material length needing severing.Cutting device 2 is arranged at
At the benchmark 0. 6 of conveyer device 5.
Image collecting device includes that pick-up lens 3, pick-up lens 3 are positioned at the surface of conveyer device 5, the side of pick-up lens 3
To the upper surface towards conveyer device 5, the end face of pick-up lens 3 is parallel with the upper surface of conveyer device 5；Pick-up lens 3
Center and image center 7 are positioned at same perpendicular.
Controller includes data receipt unit, computing unit；Data receipt unit receives the image information of image acquisition device,
Computing unit calculates control signal, and cutting device 2 receives the control signal of controller, performs severing action.Dynamical system receives
The control signal of controller, controls the transporting velocity of conveyer device.
Also include light source 4, be arranged on the side of pick-up lens 3, towards the camera watch region of pick-up lens 3.The irradiation of light source 4
Region will cover pick-up lens 3 detection range, for providing the working environment of illumination for the work of pick-up lens 3, it is to avoid due to
Light is the darkest, causes the image acquisition Quality Down of pick-up lens 3.
The position of benchmark 0. 6 or image center 7 is adjustable, i.e. the position of camera head 3 is not fixing, but can move
Dynamic.This structure is the demand in order to adapt to multiple severing length, if the position of the position of camera head 3 is fixing, the most only
The demand of a kind of severing specification can be met.Design moving track, camera head 3 is arranged on moving track, when needs adjust

If needing a length of l of severing sizing material, according to the length of the sizing material needing severing, set benchmark 0. 6 and image center 7
Position, fixing cutting device 2 and the position of pick-up lens 3, make distance therebetween equal to l；
Sizing material is placed on conveyer device, start dynamical system, conveyer device work, sizing material by benchmark zero point to image center
Direction carries；
If the detection range of pick-up lens 3 is that " L " (" L " is for representing the lateral length scope that pick-up lens 3 is taken pictures, general feelings
Under condition, the shot region of pick-up lens 3 is circular, and " L " is for representing the diameter of camera watch region), sizing material enters pick-up lens 3
Detection range start, pick-up lens 3 starts work, and the picture of shooting is delivered to controller；
The picture that controller analysis receives, calculates the alternate position spike Δ e between position and the image center 7 of sizing material stub bar, then sizing material
Distance S=l-Δ e between stub bar and benchmark 0. 6；
When alternate position spike Δ e between the position and image center of sizing material stub bar is zero, S=l, now, benchmark zero point and image
The length of the sizing material between central point is equal to the length of sizing material to be cut off.Start shearing device, sizing material is cut off.
