Description

The method and the wrapping machine thereof of bag large cylindrical external surface

Technical field

The present invention relates to a kind of method for large cylindrical external surface parcel packing; In particular for the external packing of coil of strip, characteristic is that the unsteady guide plate of employing is smoothed out with the fingers straight packing, adopted measures such as roller shutter direct packets package material successfully is rolled onto on the reel, the employing ball pivot supports reel adaptation installation working accuracy to pack.

Background technology

At present, the immediate method of this technology that relates in the packed steel coil, there is use in factory abroad; The data of taking back according to the spectator shows that its method is to launch packing earlier, cuts off blanking according to the required materials length of packing; The packing of blanking are rolled onto (the not demonstration of how to roll up) on the reel in advance; Remaining end is pressed in the top of coil of strip, and reel is done planet motion around coil of strip, and the packing that are rolled onto in advance on the reel launch to be wrapped in coil of strip in appearance from the reel extraction thereupon.During blanking viscose glue spread upon the end of packing; Wait to hold to nearly when week; An other cylinder of its reel is pressed in packing on the coil of strip; Above the packing end that the packing head end is pressed in smeared viscose glue, packing are wrapped in the purpose on the coil of strip thereby reached automatically.Planet partly comprises reel and cylinder, and reel includes shell, and packing are twisted in the shell; So just the planarization to packing has proposed higher requirement; And at present the domestic packing that are used for packed steel coil generally adopt is the heavy wrapping material that different physical strengths of having of compound one or more layers plastic woven cloth of anti-rust base paper and barrier are required, because compound preceding each layer tension force differs, very easily curling after compound; Or anti-tarnish paper has in use adsorbed the expansion of making moist of airborne moisture; Also can cause batching, one of which is difficult for carrying and importing when in reel, batching like this, and its two easy card gets lodged in the reel.

Summary of the invention

Use the easy packing that curl for adapting to national conditions; Must overcome above-mentioned deficiency; The present invention can solve the problem of the said equipment fault be prone to cause because packing curl effectively through the measures such as reel of adopting unsteady guide plate, roll coil of strip curtain, and has solved the overall with that adopts this method to pack to be run into and open entirely and problem such as concentric interference.

The technical solution adopted for the present invention to solve the technical problems is explained as follows according to process sequence:

Feeder is selected the packing of required specification according to the coil of strip oad of needs packing on the manufacturing line and is seen off by its pinch roll (1) (seeing the Figure of description code name, down together), and the content of feeder is not done detailed argumentation here not in the application's case.The packing that feeder is seen off (4) can guarantee to see off certain distance, but can not guarantee long distances, and its carrying method is to pinch packing by a pair of pinch roll; The below that packing pinch face (through 2 pinch roll clamping points and the face tangent with two pinch rolls) is level and smooth supporting plate, and packing are clipped along supporting plate by pinch roll and see off forward, and supporting plate is a level; Because the influence of tension force between the packing composite bed, the packing on the horizontal supporting plate very easily curl in course of conveying, roll up while sending when serious; Can't see off, the present invention at first solves the transportation problem after packing come out from pinch roll for this reason at all, and the method for head it off of the present invention is to utilize deadweight to carry; That is to say level and smooth supporting plate is foreshortened to the length that can send to less than feeder, the packing that continue to see off are according to the deadweight below of dangling from the supporting plate forward position, the length that the packing front end curls since the deadweight effect shorten; The phenomenon of curling can not take place while sending again, just can not launch (like Fig. 1) fully, when the length of seeing off when packing is enough; The supporting plate elongation, the packing that the supporting plate forward position promotes to dangle make it lifted (smoothing out with the fingers) gradually to supporting plate, and packing termination, supporting plate elongation back is smoothed out with the fingers to place, supporting plate forward position (4 among Fig. 3); Curl once more after smoothing out with the fingers on the supporting plate for fear of packing, above the position, supporting plate forward position after the supporting plate elongation, the front end that an object (5) is pushed down packing is set, packing are in the process of supporting plate elongation; Because the double action of inertia and air resistance (or centnifugal force and air-flow); Curling is unfolded (Fig. 2, Fig. 8), but under curling very serious situation, curling, difficulty is unfolded; In this case; Can in the process of feeding, see longer packing off, make to still have part to dangle outside supporting plate after the supporting plate elongation, oppositely regain packing afterwards to desired location; The object combined action of supporting plate and its top can brush curling part (among Fig. 34 ' and 4 " be the pilot process of withdrawal when serious of curling) during withdrawal, so can solve the transportation problem of packing.

Need packing be rolled onto on the reel (5) afterwards, the method that the present invention adopts is that one not only is used to batch packing but also be used for the independently reel that roll extrusion is pasted; A curtain (6) is set on reel, and an end of curtain is fixed on the reel outside face, and the other end freely launches; Curtain can twist on the reel cylindrical at the reel time rotational, and curtain is used for coil packing material usefulness, and principle is under the situation of launching curtain; Packing are delivered to curtain and the tangent interior angle of reel, curtain is pressed on the termination of packing, promptly be pressed in packing between reel and curtain; Make reel rotation then, feeder work feeding simultaneously, the speed of feeding and the speed of reel appearance scrolling are similar to that identical (originally reel slightly can set up tension force soon; After tension force formed, because load strengthens, it is identical that motor speed drops to speed); Curtain is rolled in the outside of packing stub bar with scrolling, owing between curtain and reel certain pressure is arranged, receives the friction force of reel and curtain respectively in the interior outside of packing; Packing under the guiding of curtain by being batched on reel, when this cans be compared in our daily life with the wrapper wall calendar, after wall calendar is rolled; Reserving one section endways is pressed in wrapper between a section that the wall calendar end stays and the volume that has been rolled into; Together twist in together with latter end and wrapper then, curtain of the present invention promptly cans be compared to one section that end is reserved when wrapping wall calendar, plays the effect that the direct packets package material is involved in smoothly.That object (5) that above the position, supporting plate forward position after the supporting plate elongation, is provided with when said reel (5) promptly is front conveying and packaging material; 6 positions of reel (or 270 degree positions or) are to need certain clearance between the splint upper surface of nadir and elongation of reel; Guarantee that supporting plate does not clash into reel when elongation; The gap can not be too big, can't avoid once more curling thereby can not push down crimp end too greatly.

The supporting plate of said elongation is partly called unsteady guide plate (3) in the following text, and the supporting plate of elongation is not partly called resting guide (2) in the following text, and reel is called the roller shutter reel in the following text or is called for short reel together with curtain.Roller shutter reel and feeder outlet pinch roll is parallel, and the moving direction of the guide plate that floats is vertical with feeder outlet pinch roll, by pinch roll to reel for stretch out when unsteady guide plate (undefined before be described as supporting plate elongation) reverse mobile be to withdraw.The resting guide upper surface nearly pinch roll place be positioned at axis be level pinch roll the face that pinches below; Drop on after packing are seen off by pinch roll resting guide above; Float guide plate below resting guide, resting guide very in short-term, the guide plate that floats tilts or stands on resting guide below (see figure 8); Its rear end, back is stretched out below the forward position of resting guide in the parallel below (Fig. 2) that places resting guide when longer, unsteady guide plate.Is that step is downward from the pinch roll face that pinches to the unsteady guide plate upper surface that stretches out.

Roller shutter (6) is a deployed condition before not pressing packing, and after packing put (unsteady guide plate is slightly being stretched out between unsteady guide plate and the reel nadir in the end) in place, one was helped bag apparatus that roller shutter is pressed on the packing, and packing are between roller shutter and reel.The part that helps bag apparatus to lift (contact) roller shutter is roller (7) (calls in the following text and help the bag roller); This roller is parallel with spool axis; Help bag roller (7) that packing are started when pushing down, what be against the packing another side can be that reel also can be an other roller or a face (call in the following text and keep out upholder).Keeping out upholder, to adopt the advantage of reel be simple in structure, and shortcoming is that roller shutter does not have tension force (like the right figure of Fig. 4, the preceding formation of compacting bulge can't be eliminated afterwards) when take-up, hold the later stage reel be pressed in coil of strip go forward (before being roll extrusion) be prone to be drawn out of and come off; The advantage of employing face also is simple in structure, can be against on the guide plate that floats (the plate face back side or its support body), and roller shutter has tension force when take-up, and shortcoming is that roller shutter and unsteady guide plate are cliding friction, roller shutter easy to wear; Adopting the advantage of roller (8) is that tension force is arranged on the roller shutter; Be the fricton-tight wearing and tearing of rolling inside and outside the roller shutter; Shortcoming is the structure relative complex; And or keep out backing roll (8) or help bag roller (7) to go up the friction link must be arranged, when making the rolling of one of two rollers resistance is arranged, make roller shutter that tension force arranged when batching packing with this.

Tension force when on reel, batching can make packing closely twist on the reel; Can not set up tension force on the packing when reel is not pasting coil of strip and does planet motion when holding coil of strip like this, packing are tightly being reined in be wrapped on the coil of strip, if there is not tension force when on reel, batching; When holding the later stage, be prone to come off; Need make reel be affixed to coil of strip as early as possible for avoiding coming off and press packing, can not tighten up the packing of absent-mindedness but roll, its parcel effect is not as good as reining on coil of strip.Especially rolling needs the planet motion center concentric with the coil of strip axle center, and this just need make device structure have corresponding ability.

The present invention is releasing constraint with one heart, is provided with elastic link in the driving of reel radius reducing and between by driving, and the slide (calling the planet seat in the following text) (20) that connects drum shaft can be gone up mobile in the swing arm that can swing (22); The rotating shaft of swing arm and coil of strip parallel axes; The present invention contacts with coil of strip for avoiding reel complete cycle when doing planet and hold, and specially requires the swing arm rotating shaft to be lower than the coil of strip axle center, guide rail is arranged in order to support the planet seat in the swing arm; Guide direction is perpendicular to the swing arm rotating shaft; Guiding linear bearing (23) is arranged on the planet seat, along the guide rail direction screw mandrel (24) is arranged, the two ends of leading screw are fixed in the swing arm by bearings; One end of leading screw is for rotating input end, and input end is connected with motor through driving device.The screw (17) that screws with leading screw is fixed on the connecting panel (18), and connecting panel connects through elastic element (19) and planet seat, when swing arm is in 12 positions of hour hands promptly vertically upward the time; The planet seat is pressed on the connecting panel through spring (19) forward, and the spring pressurized is the interposition of spring, swing arm vertically upward the time leading screw rotate screw moved to oscillating axle (reduced radius) direction; The planet seat is pressing spring to diminish with its radius, and the load weight of planet seat alleviated when reel was pressed on the coil of strip, and the spring elongation is a working position of spring; This is made as the sender position of swing arm swing head-pulley when being pressed on the coil of strip, and the expression reducing puts in place and can swing, and planet seat radius becomes big (swing arm vertically upward) and arrives at when batching the packing timber material level; Reel is against on the reel positioning supports wheel (25), and planet seat spring compresses once more, and this is for reaching the sender position of batching the position; The present invention is connected through driving device reel positioning supports wheel with motor; Make it become the driving wheel for inputting that reel batches packing, born by guide rail gradually because of the gravity of planet seat during the swing arm swing, its component along the action of the spring direction diminishes gradually; Pressure to spring also reduces gradually; The planet seat is pushed to the radius change by spring force and is propped up by block (21) until connecting panel greatly, and this position spring is stretched to maximum, and the planet seat reaches capacity in the elastic floating scope.

In its axle end bearing seat, bearing seat is fixed on the planet seat drum shaft through bearing fixing, and reel need make packing on full duration, all receive to open (being that above-mentioned overall with is opened entirely) in the process of holding; Otherwise may be horn-like after having wrapped; Reel was parallel with coil of strip when this need guarantee to batch, and required the whole subsequently equal keeping parallelism in the process that holds, and this requirement almost can't be accomplished; Reason is; Coil of strip is in that to be transferred to a reel that can not guarantee each coil of strip when holding all unified consistent, and secondly coil of strip is when promoting, because of volume heavily differs; Gig cantilever distortion also can be consistent, adds when equipment is installed that difficulty makes to batch position and curl position and an arm shaft line parallel etc. parallel with the gig lift arm.To hold the tensioning of overall process packing full duration in order guaranteeing for this reason, reel to be floated, can swing by a small margin; The present invention is arranged on center of oscillation on the center-of-gravity position of reel, and reel is that empty capsid is connected with ball pivot with drum shaft at the center of gravity place, and what the present invention adopted is the mechanism (5.1) (calling the pendulum hinge in the following text) of ball cage type plunging joint function; Be to have one degree of freedom restrained in 3 rotational freedoms of ball pivot bonded assembly, drum shaft is swung and can not be rotated relatively, can support axle head at bearing seat like this unidirectional damping link is set; Reel is when doing planet motion, and reel is passive rotation under the tension force effect of packing, and reel drives drum shaft and rotates; The damper of axle head can hinder rotation, but when take-up, has not required damping; So adopt the unidirectional damping structure; Because drum shaft is inserted in the reel by an end, the swing of reel does not only have constraint among a small circle, hold the slack-free purpose of overall process packing full duration but can reach.The present invention simultaneously also is provided with photoelectric code disk (26) at axle head, in order to the position of control roller shutter before batching.

The present invention adopts the deployable curling packing of guide plate that float, and can improve the adaptive capacity of equipment to packing well, no longer worries the problem that the curling influence of packing is carried; The roller shutter reel structure is simple, and reel and cylinder unite two into one, and roller shutter batches packing does not have shell; Be not prone to packing jam fault; Put hinged support and reel can be adapted to batch and drive the position and fit, the whole width tensioning of packing fits tightly parcel during parcel, and reel can fit tightly as roller and on coil of strip, guarantee sticking Quality when especially roll extrusion was pasted; The present invention can reduce equipment failure rate greatly, improves packaging quality.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the present invention is further specified.

Fig. 1 is the scheme drawing of conveying and packaging material of the present invention to overhang, floats guide plate among the figure under resting guide, adopts certain measure can make fed distance long slightly, makes to float that guide plate is parallel to be placed under the resting guide.Making the long slightly content of fed distance is not content of the present invention, will not detail.

Fig. 2 is that unsteady guide plate stretches out process packing view; When guide plate stretched out, packing were started, and crimping portion is by moving to tiltedly going up down; When curl direction up the time; Windage and force of inertia act on the packing and deployable its crimping portion, when curl direction down the time, and can straight by strip (smooth out with the fingers straight).

Fig. 3 is that unsteady guide plate stretches out the packing view that puts in place; Left figure roller shutter point of connection is arranged on 3 positions; Right figure roller shutter point of connection is arranged on 5 positions; Also can curl when serious by 4 ' or 4 in 4 positions of curling and directly to open when not serious for packing among the figure " position is retracted to 4 positions, and the comparable left figure of right figure roller shutter lacks.

Fig. 4 helps the bag scheme drawing, and left figure helps the bag roll-in keeping out on the backing roll, and right figure helps the bag roll-in on reel.Left figure is pressed in to keep out on the backing roll and can be simultaneously friction resistance moment be set helping the bag roller or keep out on the backing roll; Like this when reel batches packing; Friction moment can make and produce tension force on the roller shutter, and the roller shutter with tension force can make packing tightly be pressed on the reel, makes the packing two sides all can produce friction force; Thereby make packing set up tension force, do not have sliding the damage between packing and two rollers.Though being pressed in, right figure can make the packing two sides receive friction force on the reel equally, favourable the batching of face of contact reel, and another side is not tightened (even possibly form bulge) because of roller shutter before compacting; After the compacting because of between roller shutter and packing only the compacting point pressure is arranged, relax behind the overvoltage real point, though so absent-mindedness place twist on the reel; But zerofriction force between packing and reel, so can't set up tension force on the packing, but when if coiling speed is higher than the feeding speed of feeder; Reel and packing will skid; Friction force between roller shutter and packing make packing together relatively the part do not tightened until roller shutter of reel slippage be tensioned, the packing two sides will form friction force and make packing set up tension force gradually afterwards, right figure helps that to wrap roll-in simple in structure on reel; But form tension force skid tighten after; If formed bulge before the compacting, it is just longer relatively to tighten the time that needs, and is pressed in packing in the roller shutter just short (roller shutter certain situation under); When packing when reel is drawn out, will mistake early open and come off.
