(4), after finger-type catch arrives C point together with stock, PLC technology unit controls motor driver Accelerating running, finger-type catch leaves stock fast, and stock enters below shower nozzle with vacuum suction belt and carries out spray printing.
Possess certain correcting flexibility in the process run in AC section to make stock, in above-mentioned method of work, the absorption affinity of vacuum suction belt strengthens setting by A point gradually to C point.
In order to make deviation correcting device keep normal duty, to rectify a deviation to stock in time, after above-mentioned finger-type catch leaves C point, enter the spare time turn state or reach fixed point stop, waiting the appearance of next detecting sensor signal.
The ink-jet printer stock transmission platform with deviation-correcting function of the present invention, adopt and encoder is installed on vacuum suction belt drive system to detect the speed of service of vacuum suction belt, detecting sensor and deviation correcting device are set above vacuum suction belt, the data such as the stock speed of service that the PLC technology unit of deviation correcting device transmits according to encoder and the paper advanced position that detecting sensor is transmitted, the operational factor of setting motor driver, make stock when entering below deviation correcting device, finger-type catch is just positioned at the front side of stock along catching stock, set the speed of service of the speed of service of finger-type catch below deviation correcting device a little less than vacuum suction belt simultaneously, make stock below deviation correcting device time, front side is along being constantly subject to finger-type catch specification, when ensureing that stock arrives below shower nozzle, the forward position of stock is just parallel with shower nozzle, greatly improve the precision of ink jet printing, better enhance productivity and reduce production cost.Stock transmission platform of the present invention, structure is simple, be quick on the draw, rectifying effect is good, and method is easy to control, and is particularly suitable for the accurate location of stock in inkjet printing process.
Accompanying drawing explanation
Fig. 1 be the present invention there is the ink-jet printer stock transmission platform of deviation-correcting function face structural representation.
Fig. 2 is the plan structure schematic diagram that the present invention has the ink-jet printer stock transmission platform of deviation-correcting function.
Detailed description of the invention
As shown in Figure 1, 2, the ink-jet printer stock transmission platform with deviation-correcting function of the present invention, comprises stock transmitting device 1, shower nozzle 2, deviation correcting device 3, detecting sensor 4 and encoder 5, stock transmitting device comprises by motor-driven drive pulley 11, driven pulley 12 and vacuum suction belt 13, encoder is arranged on the power transmission shaft of drive pulley, shower nozzle, deviation correcting device and detecting sensor are installed on above vacuum suction belt by the support (without display in figure) of fixing stock transmitting device, shower nozzle and detecting sensor are placed in two of vacuum suction belt working face, shower nozzle is near driven pulley, detecting sensor is near drive pulley, deviation correcting device is between shower nozzle and detecting sensor, vacuum suction belt is made up of the sub-belt that three length is identical, certain gap 14 is provided with between sub-belt, deviation correcting device comprises servomotor 31, motor servo driver (without display in figure), initiative drive shaft 32, with slave drive axle 33, two groups around the power transmission shaft small-sized belt 34 run and the PLC technology unit (without display in figure) setting the small-sized belt speed of service, initiative drive shaft is near detecting sensor, slave drive axle is near shower nozzle, two groups of small-sized belts are by same initiative drive shaft and same slave drive axle coaxial rotation, servomotor is installed on initiative drive shaft, two groups of small-sized belt surfaces are all fixed with the finger-type catch 35 vertical with zone face, the width of finger-type catch is slightly less than the gap between the sub-belt of vacuum suction belt, PLC technology unit and motor servo driver, encoder, detecting sensor connects, motor servo driver is connected with servomotor.
Above-mentioned whole deviation correcting device also can mirror to the below being installed on vacuum suction belt working face, allow finger-type catch protrude from vacuum suction belt surface.
The using method of stock transmission platform of the present invention: as shown in Figure 1, two identification points are set immediately below deviation correcting device, be respectively A point and C point, identification point when A point is finger-type catch firm contacting printing material, C point is the identification point of finger-type catch when just having left stock, stock 6 is after flying the section of reaching and entering vacuum suction belt, run forward with vacuum suction belt, when detecting sensor detects the forward position of stock, detecting sensor passes the signal to PLC technology unit, PLC technology unit is according to the speed of service of stock, the distance of stock forward position and A point, finger-type catch at that time present position runs the distance of arrival A point clockwise (if now finger-type catch is just in B point position, namely calculate the B point distance through C point arrival A point) etc. data, calculate the operational factor of motor servo driver, make finger-type catch and stock forward position simultaneously, synchronized arrival A point is caught stock and is run, then the finger-type catch speed at A point is set a little less than the speed of service of vacuum suction belt, the speed of service of vacuum suction belt is just equaled in the speed of C point, namely finger-type catch is control by the requirement of speedup of slowing down gradually again in the speed of AC section, therefore, in the operation of AC section, the depth of parallelism in the continuous specification stock forward position of finger-type catch energy, when ensureing to arrive C point, the forward position of stock is parallel with shower nozzle, possess certain correcting flexibility in the process run in AC section to make stock, the absorption affinity of vacuum suction belt strengthens setting by A point gradually to C point, and namely A point place absorption affinity is more weak, and C point place absorption affinity is stronger, finger-type catch is after C point, stock is left in acceleration, stock is no longer by the control of finger-type catch, enter below shower nozzle with vacuum suction belt and carry out ink jet printing, absorption affinity due to vacuum suction belt near C point is comparatively strong and in strengthening situation gradually, stock arrives from C point the phenomenon not easily occurring the stroke of shower nozzle wandering off, and therefore stock can accurately be located under shower nozzle, greatly improves the precision of spray printing.
More than just the present invention has the ink-jet printer stock transmission platform of deviation-correcting function and illustrating of a method of work embodiment thereof; this embodiment is also not used to limit the scope of the invention; all equivalences not departing from technical solution of the present invention are implemented or change; as the change of encoder, deviation correcting device installation site, all should be included in protection scope of the present invention.
