To setting point-blank, feeding conveyer belt 10 transmits tyre surface, cut-off knife fortune so that constant speed is continuous to cut-off knife conveyer belt 20
The speed of service of defeated band 20 is controlled by arrangements for speed regulation 60, and tyre surface is provided between cut-off knife conveyer belt 20 and feeding conveyer belt 10
The melt pit 40 of surplus buffering；Range finding sensing device 30 is arranged on the surface of melt pit 40, is measured with by sensing device 30 of finding range
The height of the tyre surface distance ranging sensing device 30 between cut-off knife conveyer belt 20 and feeding conveyer belt 10, and height is supplied to tune
Speed variator 60, arrangements for speed regulation 60 carry out real-time control according to height to the speed of service of cut-off knife conveyer belt 20.
Further, arrangements for speed regulation 60 include analog-to-digital conversion module 61, processor 62, controller 63, motor 64；Range finding sensing
Device 30 is used to measure in real time the height of the tyre surface fallen into melt pit 40, and height is supplied into analog-to-digital conversion module 61, modulus
Modular converter 61 is used to provide the height after treatment to processor 62, processor 62 be used for the speed of feeding conveyer belt 10 and
Height after the treatment of analog-to-digital conversion module 61 carries out computing, obtains corresponding real-time speed, and real-time speed is supplied into control
Device 63, the controlled motor 64 of controller 63 is rotated according to real-time speed, and motor 64 is connected with cut-off knife conveyer belt 20, for driving
Cut-off knife conveyer belt 20 runs according to the real-time rotating speed of motor 64.
Further, processor 62 includes data receipt unit 621, memory cell 622, arithmetic element 623, transmitting element
624；Data receipt unit 621 is used to receive the height of the offer of analog-to-digital conversion module 61, and memory cell 622 is used to store feeding fortune
The constant speed of defeated band 10, arithmetic element 623 is used for provide the speed of feeding conveyer belt 10 and analog-to-digital conversion module 61
Computing is highly carried out, and then obtains corresponding real-time speed, and real-time speed is supplied to transmitting element 624, transmitting element 624
For real-time speed to be sent to controller 63, the controlled motor 64 of controller 63 is rotated according to real-time speed.
In a specific embodiment, arithmetic element 623 can be by the speed of feeding conveyer belt 10 and analog-to-digital conversion module
61 height for providing carry out linear operation, and such as multiplying can so control to cut out according to the speed of feeding conveyer belt 10
The speed of service of knife conveyer belt 20, when the speed of feeding conveyer belt 10, the speed of service of cut-off knife conveyer belt 20 is also corresponded to
Comparatively fast, when the speed of feeding conveyer belt 10 is slower, the speed of service of cut-off knife conveyer belt 20 is also corresponded to relatively slowly, so that melt pit
Tyre surface in 40 does not exist the problem of windrow.
Further, tyre surface severing governing system also includes some pressure rollers 50, and some pressure rollers 50 are separately positioned on feeding transport
Top with 10 top and cut-off knife conveyer belt 20, pressure roller 50 is along feeding conveyer belt 10, the width of cut-off knife conveyer belt 20
Set, the gap that tyre surface is passed through is remained in advance between pressure roller 50 and feeding conveyer belt 10, pressure roller 50 can ensure that tyre surface was transported
Journey not sideslip, it is ensured that cut scale error.
Tyre surface is conveyed by feeding conveyer belt 10 with fixed uniform velocity, while cut-off knife conveyer belt 20 is with certain speed
Tyre surface is delivered into cut-off knife machine to be cut, during cut-off knife machine cutoff action, cut-off knife conveyer belt 20 is out of service, and feeding conveyer belt
10 still convey tyre surface to cut-off knife conveyer belt 20, so that unnecessary tyre surface bending is deposited in feeding conveyer belt 10, cut-off knife fortune
In melt pit 40 between defeated band 20, it is necessary to cut-off knife conveyer belt 20 resumes operation immediately after the completion of cut-off knife machine cutoff action, will
Tyre surface continues to be conveyed to cut-off knife machine, now, the height that range finding sensing device 30 is fallen by real-time detection tyre surface, and this is real-time
The height of change is supplied to arrangements for speed regulation 60, by processor 62 by the speed that real-time high-degree of conversion is real-time change, and then controls
Motor 64 runs according to real-time speed control cut-off knife conveyer belt 20.
For example, when the tyre surface piled up in the melt pit 40 is more, range finding sensing device 30 measure the height number for obtaining also compared with
Greatly, the speed that the now conversion of processor 62 is obtained is also larger, so that controlled motor 64 is rotated according to the larger speed, drives and cuts out
Knife conveyer belt 20 runs faster, quickly to transfer out the tyre surface piled up in melt pit 40.
Conversely, when the tyre surface piled up in the melt pit 40 is less, range finding sensing device 30 measure the height number for obtaining also compared with
Small, the speed that the now conversion of processor 62 is obtained is also smaller, so that control servomotor 64 to be rotated according to the less speed, band
The slower operation of dynamic cut-off knife conveyer belt 20, slowly to transfer out the tyre surface piled up in melt pit 40.
In this scheme of analog-to-digital conversion module 61, the speed of motor 64 is piled up situation and is become in real time according to the inner tread of melt pit 40
Change, change ladder is smaller, and smooth speed control, motor 64 operates steadily, it is possible to achieve stepless time adjustment.
Certainly, the height of real-time change can be to adjust reality according to the range finding species of sensing device 30, precision, resolution ratio
Existing.
Further, range finding sensing device 30 be laser range sensor or supersonic sounding sensing device 30, it is every can be real
What existing real-time sensing was found range is used equally to this governing system.
Further, feeding conveyer belt 10 forms the gradient with horizontal direction, is high point away from the one end of cut-off knife conveyer belt 20, in order to
It is connected between compounding operation, feeding conveyer belt 10 should ensure that certain angle.
Module or unit in embodiment of the present invention device can according to actual needs be merged, divide and deleted.
Above disclosed is only present pre-ferred embodiments, can not limit the right model of the present invention with this certainly
Enclose, one of ordinary skill in the art will appreciate that all or part of flow of above-described embodiment is realized, and will according to right of the present invention
Made equivalent variations are sought, the covered scope of invention is still fallen within.
