Description
(1) technical field:
The present invention is applicable to printing machinery, is particularly useful for needing to utilize belt platform to carry out sheet-fed conveying and the equipment of location.
(2) background technology:
Printing equipment all can carry out conveying and the positioning work of paper before processing sheet-fed.As shown in Figure 1 and Figure 2, paper is transported to the location, front lay 1 place of having lifted to the feeding positioning device for paper of prior art under the combined action of defeated paper platform paper pressing device 10 and defeated paper platform belt; In front lay 1 pair of paper prelocalization process, utilize side mark 9 to complete location, side simultaneously; Side mark 9 lifts afterwards, and below front lay 1 bottom to platform, pressure roller 3 to press down paper sheet delivery with feed rollers 4 combined action to strippers 7, so just completes a sheet positioning and course of conveying.There is following shortcoming in this kind of locate mode: 1. paper is behind front lay side mark location, because power when pressure roller presses down is unstable, paper is tilted again; 2. the front lay of this detent mechanism is below platform, takies larger space, causes the distance between front lay to strippers, and the distance of paper and pressure roller and strippers strengthens, in handshaking, produce sheet wander; 3. this detent mechanism after one-time positioning, just starts when paper has not been carried completely upwards to swing before completing, and makes front lay baffle plate scratch back side of paper, can cause the scuffing of back side of paper, increases the fraction defect of product; 4. front lay completes sheet positioning, and after below the complete bottom to platform, paper feeding point wheel just starts to press down, and within this period of time, paper is not by any control, and paper after positioning can be made to produce double offset.
(3) summary of the invention:
The object of the invention is to design a kind of feeding positioning device for paper and method of work thereof, it can solve the deficiencies in the prior art, it is by changing the locate mode of front lay, front lay can be avoided the scuffing of paper, coordinate the structure realization such as existing side mark, some wheel, strippers to the conveying of paper and location again, realize the accurate location of paper, improve the precision of postorder processing.
Technical scheme of the present invention: a kind of feeding positioning device for paper, comprises front lay, pressure roller, feed rollers, delivery platform and side mark; It is characterized in that described front lay is installed on the front upper place of pressure roller.
Described front lay is connected with the servomotor swung up and down under control front lay; Under positioning states, front lay falls and carries out prelocalization work to paper, and pressure roller lifts; Under paper feeding state, front lay is lifted, and pressure roller falls and the paper feeding of feed rollers friction of rolling.
Described pressure roller is connected with cam by connecting rod; Described cam connects propulsion source, and cam rotates the up-and-down movement controlling pressure roller; Described connecting rod and spring one end are fixed, and the other end is fixed on the part of frame or geo-stationary; Described side mark is positioned on delivery platform; Described pressure roller is positioned on delivery platform, the front of side mark; Described feed rollers is positioned at the below of pressure roller, and under paper feeding state, pressure roller is vertical with delivery platform with the axial connecting line of feed rollers.
The front of described front lay is installed and the paper of having good positioning is taken over the strippers being delivered to next station.
Described delivery platform carries paper by belt conveyor; Paper pressing device is had above described paper.
A method of work for feeding positioning device for paper, is characterized in that comprising following algorithm:
(1) paper travels forward under the effect of belt conveyor on delivery platform;
(2) paper moves ahead in process, and when moving to side mark place, side mark carries out location, side to it;
(3) paper continues to move ahead behind location, side, and feeding device carries out prelocalization to position location to paper at the effect lower swing of servomotor;
(4), after prelocalization completes, pressure roller, at the control lower swing of camming movement, pushes down the paper of having good positioning, and front lay is upwards put under the control of servomotor.
In described step (4), paper moves forward to next station under the effect of strippers.
Preceence of the present invention is: 1, feeding device is above platform, can make the reduction with the spacing of strippers after sheet positioning, reduce the error that paper produces in course of conveying in handshaking, thus improve precision; 2, front lay Serve Motor Control, precision is high, be easy to control; 3, front lay relocates lower a piece of paper when the paper tail of paper crosses locating point, can not scratch paper in process; 4, paper is by zero accelerator, pressure roller and front lay action simultaneously, paper can and front lay continuation contact a period of time after depart from front lay, the positioning precision of paper can not lose.
(4) accompanying drawing illustrates:
Fig. 1 is the structural representation of feeding positioning device for paper under positioning states involved by prior art.
Fig. 2 is the structural representation of feeding positioning device for paper under paper feeding state involved by prior art.
Fig. 3 is the structural representation of a kind of feeding positioning device for paper under positioning states involved by the present invention.
