A kind of method for controlling the suction air on suction opening 17 comprises the following steps.Firstly, giving suction channel 23 load suctions air pressure (for example,-p1 is approximately equal to -200mbar).
Once suction opening 17 is covered by page 6, then negative pressure is generated in channel 23, page 6 is sucked in the negative pressure.This When, to the second suction channel 24 load suction air pressure (for example,-p2 is approximately equal to -200mbar).With the face of switching piston 31 Product ASIt compares, passes through the biggish area A of diaphragm 32MIt pulls down switching piston 31 and opens interface channel 33.
Therefore, it is equipped with negative pressure (for example,-p is approximately equal to -200mbar) in entire switching mechanism 22, the negative pressure can incite somebody to action Page 6 is fixed.
In the next step, by the suction air shutdown of first passage 23 (that is, giving the load suction air of second channel 24 A moment after).
Switching piston 31 in the switching mechanism 22 with capped suction opening 17 (referring to Fig. 3, cut by right side arrangement Change planes structure 22) it is in an open position, and with unlapped suction opening 17 switching mechanism 22 (referring to Fig. 3, left side arrangement Switching mechanism 22) switching piston 31 closed by resilient diaphragm 32, thus on unlapped suction opening 17 no longer There is suction air.If discharging the suction opening 17 covered after page 6 continues conveying at this time, suction opening 17 Gas leakage and interface channel 33 is closed.However, in second channel 24 no matter when all air tight gas, to exist herein good Good suction effect.
In a substitution method, aspirated firstly, above-mentioned two suction channel 23,24 is loaded by means of reversal valve 34 Air-p1,-p2 (- p1=-p2 is approximately equal to -200mb), it is shown such as on the left of Fig. 3.
Interface channel 33 is in close state, so that there are pressure-p1 on suction opening 17.Gas leakage always is until suction Opening 17 is covered by page.Pass through the larger area A of diaphragm 32M, interface channel 33 is made to open (AM>AZ).Then, suction is empty Gas-p1 shutdown, also, close the interface channel 33 on unlapped suction opening 17 independently.
Fig. 4 shows the top view of conveyer belt 7.Pass through printable fabric 6 to be processed (such as useful part or folding carton Clipboard) keep some suction openings 17 capped and is therefore activated.Unlapped suction opening 17 is turned off.Therefore, lead to Crossing advantageous mode can be avoided gas leakage, also, printable fabric is sucked by good swabbing action.
