The specific embodiment
Fig. 1 is the structure chart of pendulum-type grippers mechanism under the utility model printing machine; Fig. 2 is that grippers of the present utility model mechanism is in holding the schematic diagram of paper SBR in the month; Fig. 3 is the schematic diagram of grippers of the present utility model mechanism while holding paper in the month; Fig. 4 is that grippers of the present utility model mechanism drops to the schematic diagram of cylinder surface when following.As shown in Figure 1, under printing machine of the present utility model, pendulum-type grippers mechanism comprises: be arranged on the grippers axle 5 on cylinders of printing press 1; Be fixed on the grippers 3 on grippers axle 5; Be arranged on grippers axle 5 and match with grippers 3 to realize the bite-block assembly 2 of holding paper work in the month, can rotate relative to grippers axle; The bite-block drive unit being connected with bite-block assembly 2, to drive bite-block assembly to rotate relative to grippers axle 5 after holding paper in the month, drops to below cylinder surface the end face of bite-block assembly; The gripper driving device being connected with grippers 3 to drive grippers to hold paper action in the month, and rotates with grippers axle with bite-block component synchronization after holding paper in the month, and the end face of grippers is dropped to below cylinder surface.Thereby make grippers 3 and bite-block assembly 2 when rotating along with cylinder, can not interfere with the part very near apart from cylinder surface.
Particularly, as shown in Figure 1, on cylinder 1 of the present utility model, grippers axle 5 is installed, a plurality of grippers 3 are fixedly mounted on grippers axle 5, and a plurality of grippers 3 can be rotated with grippers axle 5.Bite-block assembly 2 is also arranged on grippers axle 5, and bite-block assembly 2 comprises: a plurality ofly by bearing holder (housing, cover), be contained in the connecting portion 20 on grippers axle 5; Bar portion 21 with extending along grippers axle 5 length directions, is fixed into one with a plurality of connecting portions 20, and bite-block assembly 2 can rotate relative to grippers axle 5.Grippers 3 has matched with the bar portion 21 of bite-block assembly 2 and has held paper action (as shown in Figure 2,3, 4) in the month.
Bite-block drive unit of the present utility model comprises: be arranged on the gear shaft 6 on cylinder, be arranged in parallel with grippers axle 5, an end of cylinder 1 is stretched out in its one end; Be arranged on the driven wheel 7 on gear shaft 6, driven wheel 7 can rotate with gear shaft 6, and the number of driven wheel 7 is two, is arranged on respectively the two ends that gear shaft 6 is positioned at cylinder 1 inside; By bearing holder (housing, cover), be contained in the bite-block gear 8 on grippers axle 5, bite-block gear 8 and driven wheel engagement, to rotate under the drive of driven wheel 7, bite-block gear 8 is fixedly connected with and is integral with the bar portion 21 of bite-block assembly 2, when bite-block gear 8 rotates under the drive of driven wheel 7, just make bite-block assembly 2 rotate relative to grippers axle 5 with it; The number of bite-block gear 8 equates with the number of driven wheel 7, is arranged on respectively the two ends that are positioned at cylinder 1 inside on grippers axle 5; One end is arranged on the bite-block rocking arm 9 of one end of stretching out cylinder 1 end of gear shaft 6; Be arranged on the bite-block roller 10 of bite-block rocking arm 9 other ends; And the bite-block cam 11 that is contained in the corresponding one end of drum shaft by bearing holder (housing, cover), contact with bite-block roller 10.
When bite-block roller 10 with cylinder 1 when drum shaft rotates, bite-block roller 10 moves along the outer contour of bite-block cam 11, when bite-block roller 10 moves to the turning point of bite-block cam 11 outlines, bite-block roller 10 swings certain angle, drive bite-block rocking arm 9 to swing certain angle, thereby gear shaft 6 is turned an angle, then drive the driven wheel 7 being arranged on gear shaft 6 to turn an angle, thereby bite-block gear 8 is turned an angle with bite-block assembly 2 together relative grippers axle 5.During design, can in the position that parts need to be installed, design accordingly as required a turning point of bite-block cam 11 outlines, thereby make bite-block roller 10 when arriving this turning point, bite-block assembly 2 turns an angle, to drop to below cylinder surface, interfere with these parts avoiding; Equally, can design accordingly in the position that does not need to install parts another turning point of bite-block cam 11 outlines, thereby make bite-block roller 10 when arriving this turning point, bite-block roller 10 backswing certain angles, thereby make bite-block assembly 2 rotate backward certain angle, to return to the state equal with cylinder surface.
Again as shown in Figure 1, gripper driving device of the present utility model comprises: the grippers cam 12 that is contained in the drum shaft other end by bearing holder (housing, cover); One end is arranged on the grippers rocking arm 13 of corresponding one end of grippers axle 5; Be arranged on the grippers roller 14 of the grippers rocking arm other end, contact with grippers cam 12.
When grippers roller 14 with cylinder 1 when drum shaft rotates, grippers roller 14 moves along the outer contour of grippers cam 12, when grippers roller 14 moves to the turning point of grippers cam 12 outlines, grippers roller 14 swings certain angle, drive grippers rocking arm 13 to swing certain angle, thereby grippers axle 5 is turned an angle, then drive the grippers 3 being arranged on grippers axle 5 to turn an angle.
The course of work of grippers of the present utility model mechanism is described below in conjunction with accompanying drawing 2,3,4.
First, as shown in Figure 2, now, grippers 3 is with bite-block assembly 2 in open configuration, and grippers 3 prepares to hold in the month paper action with bite-block assembly 2.
Afterwards, grippers 3 and bite-block assembly 2 are when rotating with cylinder, grippers 3 relative cylinder under the driving of gripper driving device counterclockwise turns an angle, and the relative cylinder of bite-block assembly 2 keeps motionless, make grippers 3 and bite-block assembly 2 closures, state as shown in Figure 3, now, grippers 3 and bite-block assembly 2 are held paper in the month.
Then, grippers 3 and bite-block assembly 2 are rotated further with cylinder, bite-block assembly 2 relative cylinder under the driving of bite-block drive unit counterclockwise turns an angle, simultaneously, grippers 3 under the driving of gripper driving device along with bite-block assembly 2 together also relatively cylinder rotate counterclockwise certain angle, the end face of bite-block assembly 2 and grippers 3 is turned to below cylinder surface, and state as shown in Figure 4, to avoid the parts close to very from cylinder surface.
After printing work completes, bite-block assembly 2 rotates clockwise relative to cylinder under the driving of bite-block drive unit, simultaneously, grippers 3 under the driving of gripper driving device along with bite-block assembly 2 together also relatively cylinder clockwise rotate, the end face of bite-block assembly 2 and grippers 3 is turned to concordant with cylinder surface, bite-block assembly 2 and grippers 3 return to state as shown in Figure 3.
Afterwards, grippers 3 continues relative cylinder and turns an angle clockwise under the driving of gripper driving device, and the relative cylinder of bite-block assembly 2 keeps motionless, grippers 3 and bite-block assembly 2 are opened again, state as shown in Figure 2, now, grippers 3 and bite-block assembly 2 are prepared to carry out next round and are held paper work in the month.
Although above-mentioned, the utility model is described in detail; but the utility model is not limited to this; those skilled in the art can modify according to principle of the present utility model; therefore, all various modifications of carrying out according to principle of the present utility model all should be understood to fall into protection domain of the present utility model.
