The specific embodiment
As depicted in figs. 1 and 2, advise 1 before this paper positioning device comprises, draw rule 2 and pressing wheel mechanism 3, before rule 1, draw rule 2 and pressing wheel mechanism 3 to be respectively equipped with before rule cam 11, draw rule cam 21 and pinch roller cam 31, preceding rule cam 11, draw rule cam 21 and pinch roller cam 31 to be fixedly mounted on the same transmission shaft 4.Rule cam 11 before above-mentioned, to draw rule cam 21 and pinch roller cam 31 be respectively preceding rule 1, draw the driving link in rule 2 and the pressing wheel mechanism 3, the engine installation of machine (printer or coating machine etc.) drives transmission shaft 4, advise cam 11 before making, draw rule cam 21 and pinch roller cam 31 to rotate synchronously, thereby advise 1 before making, draw rule 2 and pressing wheel mechanism 3 synchronous operations, finish front, side and the location, top of paper, and the conveying behind the paper location.Before rule 1, draw rule 2 and pressing wheel mechanism 3 all to adopt existing design, below their structure and working process are done simple the introduction.
As Fig. 1, Fig. 2 and shown in Figure 3, rule cam 11, preceding paper blocking piece 12 and preceding rule axle 13 before preceding rule 1 comprise, before being fixedly mounted on, preceding paper blocking piece 12 advises on the axle 13, one end of one end captive joint fork 14 of preceding rule axle 13, one end of the other end of fork 14 and connecting rod 15 is hinged, one end of hinged another fork 16 of the other end of connecting rod 15, the other end and the frame of fork 16 are hinged; Ball bearing of main shaft 18 is installed, the outline contact matching of ball bearing of main shaft 18 and preceding rule cam 11 on the pin 17 that connects connecting rod 15 and fork 16.Preceding rule cam 11 adopts disc cams.The effect of preceding rule 1 is to block paper in sheet transport direction, finishes the location, front of paper.Preceding paper blocking piece 12 is in the front end of defeated paper table top 5, shown in the arrow among Fig. 3, under the driving of preceding rule cam 11,15 motions of ball bearing of main shaft 18 drivening rods, rule axle 13 rotated before connecting rod 15 drove by fork 14, thereby paper blocking piece 12 is given prominence to defeated paper table tops 5 or is contracted to defeated paper table top below 5 before making, and carries out the location, front or allows paper pass through.
As depicted in figs. 1 and 2, draw rule 2 to comprise and draw rule cam 21, slide plate 22 and briquetting 23, its middle slide plate 22 is in defeated paper table top 5 belows and can slides perpendicular to paper feeding direction, briquetting 23 is in defeated paper table top 5 tops and can cooperates with slide plate 22 clamps paper, draw rule cam 21 to adopt the flute profile cylindrical cam, articulated linkage 24 on the frame, and an end of connecting rod 24 is in the groove that draws rule cam 21, the other end connects slide block 25, and slide block 25 is in transmission connection with slide plate 22 and briquetting 23 respectively.Draw rule 2 to be located at a side of defeated paper table top 5, its effect is the side draw paper and makes paper keep to the side to align, finish the side location of paper, shown in the arrow among Fig. 1, under the driving of drawing rule cam 21, connecting rod 24 swings, slide block 25 can drive slide plate 22 along sliding perpendicular to defeated paper direction, and slide block 25 also can drive briquetting 23 and be pressed between briquetting 23 and the slide plate 22 paper and shifted laterally, and paper is pulled to the side shield place, finish lateral register, draw rule 2 to reset afterwards.
As Fig. 1, Fig. 2 and shown in Figure 4, pressing wheel mechanism 3 comprises pinch roller cam 31, pinch roller 32 and pinch roller support 33, pinch roller 32 is installed in rotation on the pinch roller support 33, pinch roller support 33 is fixedly mounted on the pinch roller oscillating axle 34, one end of one end captive joint fork 35 of pinch roller oscillating axle 34, one end of the other end of fork 35 and connecting rod 36 is hinged, an end of hinged another fork 37 of the other end of connecting rod 36, and the other end and the frame of fork 37 are hinged; Ball bearing of main shaft 39 is installed, the outline contact matching of ball bearing of main shaft 39 and pinch roller cam 31 on the pin 38 that connects connecting rod 36 and fork 37; Pinch roller 32 is in the top of defeated paper table top 5 and does to cooperate with the defeated paper driving wheel 6 that is in defeated paper table top 5 belows.Pinch roller cam 31 adopts disc cam, and it is the driving link in the pressing wheel mechanism, is used to control the rising or the decline of pinch roller 32; Pinch roller 32 can be failed paper with defeated paper driving wheel 6 snug fit, also can push down paper, prevents paper displacement when carrying.Do not contact with paper when pinch roller 32 is in hoisting position, paper is by preceding rule 1 and draw rule 2 to carry out front and side location; When pinch roller 32 is in lowering position, paper is pressed between pinch roller 32 and the defeated paper driving wheel 6, paper is transported to printing or multiple film device, and this process is by 31 controls of pinch roller cam.Shown in the arrow among Fig. 4, under the driving of pinch roller cam 31, ball bearing of main shaft 39 drivening rods 36 move, and connecting rod 36 drives pinch roller oscillating axle 34 by fork 35 and rotates, thereby make the pinch roller 32 that is installed on the pinch roller support 33 rise or descend.
Before rule 1, draw the rule 2 and the concrete action rule of pressing wheel mechanism 3 respectively by preceding rule cam 11, draw curved profile or the groove decision separately of rule cam 21 and pinch roller cam 31, the operating procedure of whole paper positioning device is then also relevant with the setting angle of three cams on transmission shaft.
The installation shaft 7 of above-mentioned transmission shaft 4, preceding rule axle 13, pinch roller oscillating axle 34 and defeated paper driving wheel 6 all by bearing installation on frame, and be parallel to each other.
Usually paper blocking piece 12, pinch roller 32 and pinch roller support 33, defeated paper driving wheel 6 all are provided with several before, and more succinct in order to make figure, above-mentioned three parts all only draw one in Fig. 1 and Fig. 2.
The work of this paper positioning device is carried out according to following steps: paper is fed forward on defeated paper table top 5, and the preceding paper blocking piece 12 outstanding defeated paper table tops 5 of preceding rule 1 block the front of paper, finish the location, front of paper; Advise 2 with the paper side draw with post-tensioning, draw rule 2 one sides to be provided with side shield, when paper touches side shield, because the resistance of side shield is greater than the pulling force that draws rule 2, therefore draw the holding paper parts of rule 2 to skid at paper surface, paper can be blocked by side shield and finish side and locate; After front edge of sheets and side were finished the location, the preceding paper blocking piece 12 of preceding rule 1 moved to defeated paper table top below 5; Pinch roller 32 descends and pushes down paper subsequently, matches with defeated paper driving wheel 6, fails paper, and paper promptly is sent to next device (printing or multiple film etc.); Pinch roller 32 rose after paper sheet delivery finished, and drew rule 2 to reset.Repeat above program, can carry out location, the conveying of paper continuously.Before rule 1, draw the same axle mounting of rule 2, the cam of pressing wheel mechanism 3, guarantee above-mentioned paper location, carry the correct order and the accuracy rate of each step.
Before rule 1, draw rule 2 and pressing wheel mechanism 3 also can adopt other structure of the prior art (as drawing gauge mechanism and preceding gauge mechanism in " the full automaticity coating machine " of Chinese patent CN2635362Y bulletin), also can design voluntarily, its requirement is that each mechanism has a cam as driving link; Used cam can be disc cam or cylindrical cam.
