Embodiment of the present utility model is illustrated by particular specific embodiment below, those skilled in the art can be by this
Content disclosed by specification understands other advantages and effect of the present utility model easily.
Fig. 1 is referred to Fig. 2.It should be clear that structure depicted in this specification institute accompanying drawing, ratio, size etc., only to
Coordinate the content disclosed in specification, so that those skilled in the art understands and reads, be not limited to the utility model
Enforceable qualifications, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or size
Adjustment, in the case where not influenceing the effect of the utility model can be generated and the purpose that can reach, all should still fall in the utility model
In the range of disclosed technology contents can be covered.Meanwhile in this specification it is cited as " on ", " under ", " left side ",
The term on " right side ", " centre " and " one " etc., understanding for narration is merely convenient to, and it is enforceable to be not used to restriction the utility model
Scope, its relativeness are altered or modified, enforceable when being also considered as the utility model in the case where changing technology contents without essence
Category.
As shown in figure 1, the utility model provides a kind of break detection device for cutting, it includes controller, and
The laser range sensor 1 of the side of blade 3 of cut-off knife is placed in, laser range sensor 1 is connected with controller, the laser ranging
Obliquely downward, and the point distance measurement of laser 2 that laser ejecting end projects is on cutterhead 4, and blade for the laser ejecting end of sensor 1
3 be placed in laser 2 through in path.The utility model realizes the real-time inspection of cutting cutter 3 using laser range sensor 1
Survey, breaking phenomenon can be found in time, so as to the timely more allowing blade replacement of operating personnel；In addition, the utility model senses laser ranging
Laser detection region emitted by device 1 is cutterhead 4, therefore laser is beaten on blade 3, does not trigger feedback signal；When blade 3 is disconnected
After, the laser beam of laser range sensor 1 can pass through and detect cutterhead 4, and controller is judged as breaking, and feedback letter
The general control system of cutting number to be given, shows breaking information, whole detection process only needs laser range sensor to send laser,
Its is simple in construction to be easily installed setting, the less state of the installing space especially suitable for cutting cut-off knife.
For the more accurate actual state of detection blade, avoid drawing the floating objects such as fragment in use environment and give laser ranging
Sensor influences, and laser range sensor 1 is two in the present embodiment, and is symmetrical arranged on blade 3.From there through two or
More than two laser range sensors 1 carry out multi-orientation detection to blade in real time, improve the accuracy of detection.
More accurately to detect the actual state of blade, avoid thering is mark of break to occur without being discovered when cutting, the present embodiment
In the joining of the laser that projects of above-mentioned laser ejecting end and blade 3 be located at the lower section of prediction breaking point on blade, that is, setting
During laser range sensor, the characteristic of the knife grinding mechanism first set according to cutting itself, next advance test blades are likely to occur disconnected
The breaking point of knife, laser path is then set completely to be detected to blade with this by the lower section of all prediction breaking points.One
As be the lower section that laser path is placed in blade, the pars intermedia of blade and top can fully be examined when blade is cut
Survey, the mark of break being consequently adapted on blade is generally present in the situation at top and middle part.
The joining of the laser that above-mentioned laser ejecting end projects in the present embodiment and blade 3 is located at the point of a knife four from blade 3
At/mono-, to realize the preferably abundant detection to blade top and middle part.
The utility model also provides a kind of knife-breaking detecting method for cutting, and the knife-breaking detecting method is using as above institute
The break detection device for cutting stated is detected, and the knife-breaking detecting method includes：Cutting enters cutting state, described
Break detection device starts to detect, when the laser emitted by laser range sensor is exposed on the blade, laser ranging
For sensor feedback-less signal to the controller, controller judges blade without mark of break；When swashing emitted by laser range sensor
When illumination is incident upon the cutterhead, laser range sensor feedback signal to the controller, the controller judges have on blade
There is mark of break.The utility model sends laser in real time by laser range sensor, by the way that whether laser range sensor is detected
To cutterhead for identification whether the standard of breaking, i.e., when the laser emitted by laser range sensor is exposed on the blade,
For laser range sensor feedback-less signal to the controller, controller judges blade without mark of break；When laser range sensor institute
When the laser of injection exposes to the cutterhead, laser range sensor feedback signal to the controller, the controller judges
There is mark of break, the detection process precision is high, and is easily achieved on blade.
In the present embodiment during cutting cutting, breaking also includes following deterministic process when detecting, such as：
As shown in Fig. 2 before the break detection device starts detection, the laser ranging sensing is preset in controller
Device detects the rotation angle range of blade, and when the break detection device detects, the controller obtains working as blade in real time
The preceding anglec of rotation, and present rotation angel degree is judged whether in default rotation angle range, if then controller obtains in real time
Take the laser range sensor whether there is feedback signal, mark of break judgement is carried out to blade；If not the Laser Measuring is not received then
Feedback signal away from sensor, blade is judged without mark of break.
Before the break detection device starts detection, predicted according to the knife grinding mechanism in the cutting on the blade
All breaking points, the laser emitted by the laser range sensor and the joining of blade are set under all breaking points
Side, it is ensured that completely detected to blade.
The present embodiment improves the precision and detection efficiency of breaking detection with this by setting up above-mentioned deterministic process.
The present embodiment also includes：When the controller judges breaking, controller sends letter to the general control system of cutting
Number, make cutting stop cutting, cutting sends the signal for changing cut-off knife.The signal for changing cut-off knife is sent, and makes operating personnel timely
Know, so that operating personnel change cut-off knife in time, improve and cut efficiency.
In summary, the break detection device and detection method of the present utility model for cutting, whole detection process is only
Laser range sensor is needed to send laser, its is simple in construction to be easily installed setting, the installation especially suitable for cutting cut-off knife
The less state in space.So the utility model effectively overcomes various shortcoming of the prior art and has high industrial utilization
Value.
Above-described embodiment only illustrative principle of the present utility model and its effect are new not for this practicality is limited
Type.Any person skilled in the art can all be carried out without prejudice under spirit and scope of the present utility model to above-described embodiment
Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from the essence disclosed in the utility model
