Abstract
The utility model relates to a paper feeding positioning device which comprises a front guide, a paper pressure wheel, a feed roller, a paper feeding platform and a side guide and is characterized in that the front guide is arranged at the front upper side of the paper pressure wheel. The paper feeding positioning device has the advantages that the front guide is arranged above the platform, and thus, the distance between positioned paper and a paper receiving device can be reduced and an error generated in the conveying process of paper is reduced in the handshaking process, so that the accuracy is improved.
Description
(1) technical field:
The utility model is applicable to printing machinery, is particularly useful for utilizing the belt platform to carry out the equipment that sheet-fed is carried and located.
(2) background technology:
Printing equipment all can carry out conveying and the location work of paper sheet-fed being carried out first being processed.The feeding positioning device for paper of prior art as shown in Figure 1 and Figure 2, paper is transported to the location, front lay 1 place of having lifted under the combined action of defeated paper platform paper pressing device 10 and defeated paper platform belt; In 1 pair of paper prelocalization of front lay process, utilize simultaneously side mark 9 to finish the side location; Side mark 9 lifts afterwards, and front lay 1 bottom is to platform, and pressure roller 3 presses down with feed rollers 4 combineds action paper sheet delivery to strippers 7, so just finishes paper location and course of conveying.There is following shortcoming in this kind locate mode: after 1. paper was located through the front lay side mark, the power when pressing down owing to pressure roller was unstable, and paper is tilted again; 2. the front lay of this detent mechanism takies than large space below platform, causes front lay to the distance between the strippers, and the distance of paper and pressure roller and strippers strengthens, and produces sheet wander in handshaking; 3. this detent mechanism is before finishing after the one-time positioning, carry fully at paper just to begin when finishing upwards to swing, so that front lay baffle plate scratch back side of paper,
Cause the scuffing of back side of paper, increase the fraction defect of product; 4. front lay is finished paper location, and the bottom is after below the platform fully, and paper feeding point wheel just begins to press down, this section in the period paper be not subjected to any control, can make the paper generation double offset of having located.
(3) utility model content:
The utility model purpose is to design a kind of feeding positioning device for paper, it can solve the deficiencies in the prior art, it is by changing the locate mode of front lay, can avoid front lay to the scuffing of paper, cooperate again the structures realizations such as existing side mark, some wheel, strippers to conveying and the location of paper, realize the accurate location of paper, improve the precision of postorder processing.
The technical solution of the utility model: 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 links to each other with the servomotor that control swings up and down under the front lay; Front lay falls paper is carried out prelocalization work under the positioning states, and pressure roller lifts; Front lay is lifted under the paper feeding state, and pressure roller falls and the paper feeding of feed rollers friction of rolling.
Described pressure roller links to each other with cam by connecting rod; Described cam connects propulsion source, and cam rotates the up-and-down movement of control pressure roller; Described connecting rod and spring one end are fixed, and the other end is fixed on frame or the relatively static part; Described side mark is positioned on the delivery platform; Described pressure roller is positioned on the delivery platform, the place ahead of side mark; Described feed rollers is positioned at the below of pressure roller, and the axial connecting line of pressure roller and feed rollers is vertical with delivery platform under the paper feeding state.
The place ahead of described front lay is installed the paper of having good positioning is taken over the strippers that is delivered to next station.
On the described delivery platform by the belt conveyor conveyance of sheets; There is paper pressing device described paper top.
Working process of the present utility model:
(1) paper travels forward at delivery platform under the effect of belt conveyor;
(2) during paper moved ahead process, when moving to the side mark place, side mark carried out the side location to it;
(3) paper continues to move ahead behind the side location, and feeding device carries out prelocalization to the position location to paper at the effect lower swing of servomotor;
(4) after prelocalization was finished, pressure roller was pushed down the paper of having good positioning at the control lower swing of camming movement, and front lay is upwards put under the control of servomotor.
Paper moves forward to next station under the effect of strippers in the described step (4).
Preceence of the present utility model is: 1, feeding device can make behind the paper location and the reducing of distance between the strippers above platform, has reduced the error that paper produces in the handshaking in course of conveying, thereby has improved precision; 2, front lay is controlled with servomotor, and precision is high, be easy to control; 3, front lay is to relocate lower a piece of paper when the paper tail of paper is crossed locating point, can not scratch paper in the process; 4, paper is in by zero accelerator, and pressure roller and front lay are moved simultaneously, paper can and the front lay continuation break away from front lay after contacting a period of time, the accuracy of positioning of paper can not lose.
