In said method, the process of the roller-way rotating speed Vx of described reading conveyer is: control device generates by communication module access adhesive polystyrene granule heat-insulating plate the data that control system directly obtains Vx automatically.
Below several key link of the present invention is described.
One, cutting process:
Cylinder action, sawtooth declines, and sawtooth has driven by motor rotation to cut, and the stepper motor band saw of turn-screw advances along cutting track simultaneously, then stops to edge limit switch when cutting is complete.Now, cylinder action, sawtooth rises, and motor stops, and original position is got back in the reversion of screw mandrel stepper motor.Cutting process is complete.
Two, the location of sawtooth:
Track be advance, glue powder polyphenyl particle plate also always run (moving horizontally), if so saw do not advance may by saw extruding fracture.If take screw synchronous to move, the mechanism of apparatus design system increases.A kind of shortcut can be adopted at this, the position gradient of device be installed, moving horizontally of sawtooth can be realized like this.
As shown in Figure 3, glue powder polyphenyl particle plate to be cut advances along Vx direction, known in the speed of roller-way, by vertical with the direction of motion of plate for the position adjustments of saw; The horizontal gradient width W of the formation of the fixed position, two ends of cutter sweep, W should equal Vx and be multiplied by from cutting to the end time.The speed controlling cutting stepper motor can be calculated thus.When cutting, sawtooth, always in the crack of two liner plates, does not destroy liner plate like this.What leading screw drove employing stepper motor is some the cutting speed that suitably can regulate saw according to the speed of electric machines for roller, in order to avoid damage liner plate.
Three, the detection of cutter sweep cutting beginning:
How to determine that the position starting to cut is automated production process important step.
In order to accomplish to cut at the slit of two liner plates, the present invention adopts high-speed camera head, identifies cutting start time, accomplish accurate location like this with the image of shooting.As Fig. 4, the appropriate position of moment just between S of cutting.Suitable automatic fine tuning can be done according to the speed of service difference of roller-way in this position.
Four, control principle
As shown in Figure 2, camera is with protection mechanism.Prevent the pollution of human society.When glue powder polyphenyl particle plate enters into about 80% of cutting area, known by the touching switch before plate, camera protecting mechanism is opened, and single-chip microcomputer STM8S controls to start shooting, the position of slit between two plates is extracted by image edge processing, when to this cutting position point, start cylinder, open electric saw, the stepper motor simultaneously controlling leading screw moves along guide rail, stop cutting when running into limit switch, and mention saw, stop cast-cutting saw motor; Meanwhile, leading screw stepper motor reverses, and get back to home position (limit switch), so far, whole cutting work completes.Cutting times is placed in memory EEPROM by controller.Controller is connected by RS485 with automatic production control system, accepts roller-way motor rotation speed, the relevant parameters such as start-stop state.
In addition, range of application of the present invention is not limited to the technique of the specific embodiment described in description, mechanism, manufacture, material composition, means, method and step.From disclosure of the present invention, to easily understand as those of ordinary skill in the art, for the technique existed at present or be about to develop, mechanism, manufacture, material composition, means, method or step later, wherein their perform the identical function of the corresponding embodiment cardinal principle that describes with the present invention or obtain the identical result of cardinal principle, can apply according to the present invention to them.Therefore, claims of the present invention are intended to these technique, mechanism, manufacture, material composition, means, method or step to be included in its protection domain.
