Referring to Fig. 1, Fig. 2, be equiped with the epidermis wheel 22 of tool pattern printing skin 3 on the slide unit 21, by the line of induction 31 (see figure 2)s on the induction electric eye 23 detection pattern printing skins 3, by the length line of induction 32 (see figure 2)s on the length induction electric eye 24 detection pattern printing skins 3, the detection signal sending computer arithmetic element 4 of induction electric eye 23, computer arithmetic element 4 control motors 25 are adjusted and are proofreaied and correct the position, the left and right sides that epidermis is taken turns 22 dischargings.Pattern printing skin 3, middle

white skin

51,52 of end skins are taken turns 26 pairs of line pressings with texturing and are made plastic floor tile.Texturing are taken turns the linking of place, 26 axle center and are fixed a decoder 6, take turns 22 front portions at the epidermis of board 27 and then set up blowing wheel 7, and blowing wheel 7 is driven by blowing motor 71.The texturing that signal that length induction electric eye 24 detects and decoder 6 produce are taken turns 26 running speed signals, and through computer arithmetic element 4 substitution ratios, the dispensing speed of accurately controlling blowing motor 71 reaches stamp line and the synchronous involutory purpose of embossing.

Referring to Fig. 3, be the control feeding schematic diagram of

pattern printing skin

3,41 is that power supply is powered to computer arithmetic element 4, display 42 is used to show the position deviation amount of texturing wheel 26 (texturing wheel drive motor 61, decoders 6) and blowing wheel 7.Because the floor tile specification difference of making, length induction electric eye 24 must the shift position to do correct induction, in order to make induction accurately, Fig. 8, improvement pre-structure shown in Figure 7 are often adjusted the considerable time of cost in the position of setting up of length induction electric eye 24, and its result still has error.This improvement structure is arranged on suitable position as long as length is responded to electric eye 24, the signal that detects when induction is synchronously but still when having error, can directly set required correction value by the synchronous error adjuster 43 that is provided with, promptly can the add deduct operation of correction value of computer arithmetic element 4 to the signal that blowing is taken turns 7 (blowing motors 71), decoder 72, and make quick revised blowing motor 71 synchronous operations, keep the quality of the product of making.

Texturing wheel 26 is made adjustable independent operation, because device is that the running speed with texturing wheel 26 is the adjustment foundation, when beginning to start, the signal of computer arithmetic element 4 receiver decoders 6 and length induction electric eye 24, after comparison operation, the result sent driver 44, CD-ROM drive motor 71 runnings, simultaneously CRANK PULSES is feedback to computer arithmetic element 4 with the decoder 72 of blowing motor 71 synchronous operations, make blowing motor 71 in the extremely short time, enter the state that formally to produce synchronously with texturing 26 speed of taking turns, thereby trial target is few, device also is the dispensing speed of so continuous correction adjustment blowing wheel 7 in operation process, so the involutory compacting of plastic floor tile decorative pattern that this device is made is quite accurate.

But the involutory control of adjusting at random of decorative pattern has certain limit, and error can not be too big.Do not improve pre-structure and will test 25-40 piece floor tile ability automatically calibrating usually to synchronously, waste greatly.Cause fuzzy, the mistake of nonsynchronous main cause stamp line on pattern printing skin 3 and detect the error, it also is a big reason that the texturing wheel 26 of high heat makes pattern printing skin 3 meet thermal potential length, thereby this device is when the nonsynchronous error of speed surpasses a setting value, then do mandatory adjustment control by computer arithmetic element 4, be that blowing motor 71 slows down 7% speed, in the hope of synchronous next time.

Texturing wheel 26, blowing motor 71 respectively installs

decoder

6,72 additional, and it revolves synchronously to turn around and can produce 2500 (pulse) signals and initial (pulse) signal M, two members is relatively gone up synchronously can be obtained the accurate computing numerical value of suitable perfection.Actual test result is: the garden week size of texturing wheel 26 need be the integral multiple of 3 numbers of pattern printing skin, as 1 all a slices, 2,4 etc., is the best with 3.Decoder 2500 add M signal and the texturing in 3 floor tile cycles take turns 26 corresponding, speed, the position that can learn the texturing wheel.And the length line of induction 32 on the pattern printing skin 3 also only need be arranged on the original position of each sheet floor tile stamp line, the decoder signal that computer arithmetic element 4 should read when detecting the second length line of induction 32 is 833 (pulses), more then error amount can be learnt with this value, the running speed of blowing motor 71 can be accelerated or slow down.

In force adjusting control model make pattern printing skin 3 draw longlyer owing to will slow down 7% speed, could recover more subsynchronous, during will inevitably cause defective work, but compared with device before improving, its percent defective greatly reduces and recovers synchronous quickening.Never can be in order fast synchronously to make the speed of blowing motor 71 fall too lowly in the enforcement, otherwise can the phenomenon of fracture take place at the focus that is subjected to of pattern printing skin 3, test of many times result shows that to reduce by 7% be the best, walks 14 floor tiles this moment at the most and gets final product synchronous.

Referring to Fig. 4, Fig. 5, be the control flow of computer arithmetic element 4 in conjunction with Fig. 3.Because embodiment irises wipe the texturing garden of taking turns Monday to be divided into three floor tile cycles, 2500 signals of decoder also trisection at three floor tiles in the cycle, add an initial signal M, so the computer arithmetic element is that the rotating speed that can calculate texturing wheels is linear velocity and running position.In addition, blowing motor 71 is to utilize odontoid belt transmission blowing wheel folder printing skin to do the blowing action, according to tooth when each feedback signal that can calculate blowing motor decoder 72 garden week of blowing wheel be equivalent to the length of blowing, when starting this to the flower Embosser, computer arithmetic element 4 reads the running feedback signal of texturing wheel 26 earlier and as foundation, blowing motor 71 is also sent into the feedback signal of running in the computer arithmetic element relatively, takes turns 7 rotating speeds and texturing until blowing and takes turns 26 rotating speeds and reach synchronous; And then the computer arithmetic element reads texturing wheel 26 again, the CRANK PULSES that blowing wheel 7 is feedback, and detect the actual sensed signal of floor tile positions by length induction electric eye 24, the synchronous error that receives blowing wheel decoder 72 is proofreaied and correct processing signals, and then relatively proofread and correct the difference between back blowing wheel 7 and texturing wheel 26 running feedback signals, this work is mainly carried out by the velocity compensator that set up computer arithmetic element inside, when difference value in a very little limit value or during the indifference value, then only speed adjustment or keep original speed slightly of the velocity compensator of computer arithmetic element, when if difference value surpasses limit value, velocity compensator is promptly ordered blowing motor slow-down (7%), descends a slice floor tile more synchronously.

Each frame meaning is as follows among Fig. 4: 401-begins performing a programme; 402-reads texturing wheel speed and position by decoder 6; 403-calculates blowing motor center speed according to the tooth ratio; 404-sends the blowing motor speed command through driver drives blowing motor running; The 405-computer judges whether to arrive central speed by the feedback signal of blowing motor at any time; 406-map interlinking 5 programs continue to carry out.

Each frame meaning is as follows among Fig. 5: 501-reads texturing wheel location feedback signal, because of texturing wheel garden circle Monday is divided into three floor tile cycles, 2500 signals of decoder are also third-class to be divided into three floor tile cycles, cooperate the M initial signal again, the computer arithmetic element just can learn that texturing take turns the initial and running position of every floor tile; 502-reads blowing motor position feedback signal; The difference (the error corrector setting value adds that the position of blowing motor blowing promptly is the position of texturing wheel) of feeding motor position and " texturing wheel " position is proofreaied and correct and calculated according to the tooth ratio to the 503-mismatch error; 504-judges whether difference value is " 0 ", if 0 enters 506, and with the dispensing speed order blowing of trying to achieve originally and return 501, contrast difference repeatedly; If difference is not 0 and enters 505, try to achieve the blowing motor speed command with velocity compensator, and send driver to increase, subtract motor speed and return 501, contrast difference repeatedly, and velocity compensator promptly is to judge measures of dispersion, with the size of amount as the velocity compensation order; 507-sends the blowing motor speed command.

Referring to Fig. 6, be the parts connection diagram of principle shown in Figure 3, computer arithmetic element 4 adopts CPU board (UT-900 or UT-920), and CN1 to CN6 totally six interfaces are arranged.Wherein CN1 is connected with power supply 41 (MT-103).CN2 is connected with blowing servomotor drive 44 (UT-90B), blowing motor 71 (servo motor BSM-80B-375), blowing decoder 72 (OEW-25-2MD).CN3 is connected with texturing wheel decoders 6 (OEW-25-2MD).CN4 is connected with length induction electric eye, hunting motor 25 (servo motor BSM-80B-375), hunting motor driver (UT-90B), detection by left and right line
