Description

Full-automatic apparatus for binding books book clips device

Technical field

The utility model relates to a book clips mechanism on the modern perfect binding notebook packager, specifically a kind of full-automatic apparatus for binding books book clips device.

Background technology

General notebook packager mainly contains common apparatus for binding books and pneumatic type apparatus for binding books on the market now.The action of the book clips of common apparatus for binding books (clamp, keep, open) all has mechanical structure control, speed is fast, but clamping force is only by spring control, when the variable thickness sample of bookblock, the stroke of spring is also different, therefore the clamping force to bookblock also changes thereupon, thereby can influence this quality of bag of books.The action of the book clips of pneumatic type apparatus for binding books (clamp, keep, open) is all controlled by air-channel system, though this device clamping force is controlled by air pressure, clamping force is stable, because air-channel system all is installed on the book clips, thereby influenced machine run speed, yielded poorly.These two kinds of book clips structures, can not the guarantor measuring of guaranteeing the quality, what another guarantor measured can not guarantee the quality.

Summary of the invention

The purpose of this utility model is to design a kind of full-automatic apparatus for binding books book clips device.

To be solved in the utility model is the problem that existing common this quality of apparatus for binding books bag is low and pneumatic type pneumatic type apparatus for binding books yields poorly.

The technical solution of the utility model is: it comprises front plate and rear plate, be located at positioning seat and eccentric stiffener on the rear plate, it is characterized in that described eccentric stiffener comprises eccentric shaft, roller gear, needle bearing, last needle bearing, following needle bearing, fixed block and arm-tie axle, roller gear is located on the eccentric shaft, last needle bearing is connected with roller gear, following needle bearing is connected with fixed block, and needle bearing is located on the arm-tie axle, and the arm-tie axle is connected with front plate.

Use the utility model on full-automatic notebook packager, the speed that transmits in the time of can guaranteeing apparatus for binding books work can be stablized the clamping force maintenance of bookblock by the guaranty clip again, improves the quality of finished product.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

As shown in the figure, the utility model comprises front plate 9 and rear plate 10, is located at positioning seat 1 and eccentric stiffener on the rear plate 10.Described eccentric stiffener comprises eccentric shaft 2, roller gear 3, needle bearing 4, last needle bearing 5, following needle bearing 6, fixed block 7 and arm-tie axle 14.Roller gear 3 is located on the eccentric shaft 2, and last needle bearing 5 is connected with roller gear 3, and following needle bearing 6 is connected with fixed block 7, and needle bearing 4 is located on the arm-tie axle 14, and arm-tie axle 14 is connected with front plate 6.Be connected with extension spring 8 on the fixed block 7.

Operation principle of the present utility model is: book clips of the present utility model has the cylinder that is complementary with it when working.The bookblock position is equipped with a clip positioning cylinder on full-automatic notebook packager, in the book position that falls of full-automatic notebook packager another clip positioning cylinder is installed.When book clips ran to dress bookblock position, this cylinder action made book clips be transformed into clamped condition from open mode in book clips by the stretching eccentric stiffener, and when book clips moved on guide rail, this eccentric stiffener can keep this clamped condition.Up to this end of bag, when book clips moved to the book seat, another cylinder acted on the eccentric stiffener of book clips once more, made book clips be transformed into open mode from clamped condition, and so forth.Be specially:

1), the clamping process of book clips: when book clips moved to the clamping working position, 12 work of clip positioning cylinder made locating shaft 11 withstand positioning seat 1, and book clips are stopped.Lift cylinder 18 work then will be installed lifting, make the downward needle bearing 6 in jacking block 13 tops, and under pressure, following needle bearing 6 is along the motion of the inclined-plane of last jacking block 13.Drive eccentric shaft 2 motions by fixed block 7, and then drive the rotation of a pair of roller gear, and then eccentric shaft 2 is also rotated, the rotation of two eccentric shafts, produce the gap between eccentric shaft 2 and the arm-tie axle 14, just make arm-tie axle 14 loosening, 18 of lift cylinders rise device and also make pulling shaft piece 16 block needle bearing 4 on the arm-tie axle 14 simultaneously.Subsequent pulling shaft cylinder 26 work allow pulling shaft piece 16 by needle bearing 4 pulling arm-tie axles 14, and make front plate 9 press close to rear plate 10, have realized the clamping to bookblock.

2), the opening procedure of book clips: when book clips moves to when opening working position, clip positioning cylinder 27 work of the other end make locating shaft 28 withstand positioning seat 1, and clip are stopped; Going up simultaneously needle bearing 5 just moves to down on the jacking block 20, needle bearing 5 is moved along the gradient of following jacking block 20, drive a pair of roller gear 3 motions, thereby a pair of eccentric shaft 2 is rotated, the rotation of two eccentric shafts, make between eccentric shaft 2 and the arm-tie axle 14 and produce the gap, make arm-tie axle 14 loosening; Motor 25 runnings drive screw mandrel 23 quick rotation then, make guide pad 22 arrive ad-hoc location; Last push shaft cylinder 26 work allow apical axis circle 21 head on arm-tie axle 14 and travel forward, and make clamping plate open fully.

3), hold mode: after clamping plate clamp, lift cylinder 18 descends, jacking block 13 and following needle bearing 6 are broken away from, roller gear 3 is rotated by the effect of extension spring 8, eccentric shaft 2 also reverses simultaneously, two eccentric shafts tighten arm-tie axle 14 after turning over certain angle, and it is fixed, and then have kept the state that clamps; The needle bearing 4 that the decline of lift cylinder 18 simultaneously also makes pulling shaft piece 16 break away from the arm-tie axle 14.Clip positioning cylinder 12 reverse operations make locating shaft 11 break away from positioning seat 1 then, and whole like this clip just can move.
