Description
[technical field]
The utility model relates to rotary printing equipment, relates in particular to direct rotary machine secondary tenslator.
[background technology]
On rotary press, two kinds of tension force are arranged, one is unwinding tension, and this tension force is one-level tension force, and paper must have certain force of strain could print and continuous tension stability in the rotary press printing process.Because the press printing process is to reach eight meters to ten meters distance, like this, one-level tension force has instability, uneven situation, and in the multiple printing, the tension force of each couplet just has inequality like this, and unsettled situation causes the problem of gathering leaves of a book.
[utility model content]
The utility model provides a kind of and is applied on the rotary press; The tension force of paper in printing process is carried out secondary detection, correction; Do not cause not to the hole, not to advising the problem of position owing to the different tension force that cause of paper are steady when avoiding joining the bills printing more; Reach tension stability, gather leaves of a book printing precisely, endorsement do not run rule, chase after that seal is accurate, chromatography is accurate, the direct rotary machine secondary tenslator that the product of making is attractive in appearance, smooth.
In order to realize above-mentioned utility model purpose, the technical scheme that the utility model adopts is:
Direct rotary machine secondary tenslator; Include paper roller, go out paper roller, pressure roller and cross paper bowl; Going into paper roller and going out to be provided between the paper roller transmitting a plurality of paper bowls of crossing of printing paper, a pair of pressure roller respectively with go into paper roller and go out the paper roller compression fit and transmit printing paper; Saidly go into paper roller by going into the paper driven by servomotor, be provided with and go into the paper servomotor and be electrically connected and can measure the first signal feedback encoder of printing paper speed going into the paper roller place; Go out paper roller by the paper delivery driven by servomotor, be provided with the secondary signal feedback coder that is electrically connected and can measures printing paper speed with the paper delivery servomotor going out the paper roller place; The said first signal feedback encoder also is connected with isochronous controller respectively with the secondary signal feedback coder, and isochronous controller is connected with the servo controller that paper servomotor and the speed governing of paper delivery servomotor are gone in control.
The said tension pick-up that is provided with printing paper tension force in the control transport process between the paper bowl of crossing; Tension pick-up is connected with tension controller, and said servo controller is according to the tension force size of the printing paper speed of going into paper servomotor and paper delivery servomotor place through tension controller control tension pick-up.
Said first signal feedback encoder and secondary signal feedback coder are photoelectric encoder.
The beneficial effect of the utility model is:
In printing process, accurate at rotary press in order to reach better rule position, as: to join express delivery single because the demand of the position, hole of gathering leaves of a book more; Require position, a hole of 5-linked (5PLY) Kong Weiru the same, length requirement is very high, through the signal that senses according to the first signal feedback encoder and secondary signal feedback coder; And, control into paper servomotor and the speed governing of paper delivery servomotor, and further passed through the tension force of printing paper in the tension pick-up control transport process between the paper bowl through servo controller through isochronous controller; Promptly measure friction speed through former and later two encoders, increase or minimizing speed through middle tension pick-up, making the speed difference between 2 is zero; Reach the speed unanimity; Thereby reach equalization of strain, make tension force reach a stable scope, thereby when producing many couplet bills or express delivery list, gather leaves of a book precisely; Reach zero error, practice thrift cost thereby can make the tension force condition of different drop to 1%.

Fig. 2 is the utility model tension structure sketch map.
[specific embodiment]
As depicted in figs. 1 and 2; Direct rotary machine secondary tenslator; Include the paper roller (not shown), go out the paper roller (not shown), pressure roller 1 and cross paper bowl 2; Going into paper roller and going out to be provided between the paper roller transmitting a plurality of paper bowls 2 of crossing of printing paper, a pair of pressure roller 1 respectively with go into paper roller and go out the paper roller compression fit and transmit printing paper; Saidly go into paper roller by going into paper driven by servomotor 4, be provided with and go into paper servomotor 4 and be electrically connected and can measure the first signal feedback encoder 5 of printing paper speed going into the paper roller place; Drive by paper delivery servomotor 6 going out paper roller, be provided with and be electrically connected the secondary signal feedback coder 7 that also can measure printing paper speed with paper delivery servomotor 6 going out the paper roller place; The said first signal feedback encoder 5 also is connected with isochronous controller 8 respectively with secondary signal feedback coder 7, and isochronous controller 8 is connected with the servo controller 9 that paper servomotor 4 and 6 speed governing of paper delivery servomotor are gone in control.
As shown in Figure 2; Cross the tension pick-up 10 that also is provided with printing paper tension force in the control transport process between the paper bowl 2; Tension pick-up 10 is connected with tension controller 11, and said servo controller 9 is according to the tension force size of the printing paper speed of going into paper servomotor 4 and paper delivery servomotor 6 places through tension controller 11 control tension pick-ups 10.
Wherein, the first signal feedback encoder 5 is a photoelectric encoder with secondary signal feedback coder 7.
The rotary press length of the utility model approximately is about 15 meters, and therefore, the speed of each point is owing to paper is flexible; Slight difference is arranged, test the speed through 2 encoders, the speed difference of each point is the main cause that causes that tension force is different; During work, measure respectively into paper roller place and the speed that goes out the paper roller place, be transferred to servo controller 9 then through the first signal feedback encoder 5 and secondary signal feedback coder 7; The calculating of process servo controller 9 is with average; The average speed instruction of isochronous controller 8 is input to into paper servomotor 4 and paper delivery servomotor 6, and through the servomotor speed governing, and loose each point paper is strained or drawn to the tension pick-up of crossing between the paper bowl 10 according to the control of servo controller 9; Reach velocity balance, thereby reach equalization of strain.
The above embodiment just is the preferred embodiment of the utility model, is not the practical range that limits the utility model with this, and the equivalence that all shapes according to the utility model, structure and principle are done changes, and all should be covered by in the protection domain of the utility model.
