Description

Be used to produce method and apparatus through improved resilient packing product

The present invention relates to be used for making method and apparatus through improved resilient packing material.Particularly, this apparatus and method that the present invention relates to be used for slice with moistening sheet material form, flexibly bending and wrinkling become a kind of through improved binding, loose packing.

Foam polystyrene particle is in wholesale and retail business, generally as the bulk packing material.These particles are used for product orientation away from the container inside part, and with in the grain packing space betwixt.These particles are intended to protect packaged products, make it not to be hit, hit or other off-square processing.

Divide and put not too complexity of foam polystyrene particle.Particle only is a by gravity, pack space in the packing container into from big hopper in.

Yet, adopt foam polystyrene particle that many shortcomings are arranged.For example, if foam polystyrene particle is used for protecting the weight body that is contained in the container, and when this packing was collided or vibrated, object tended to by gravity, moved to container bottom, and particle upwards floats.At last, object can lean against on container bottom or the side, and object may damage.Lightweight expanded polystyrene is also moved by wind easily, and is scattered.

What arouse attention especially is, foam polystyrene particle is after use, and is extremely difficult or destroy.In fact, owing to a large amount of adopt the non-biodegradation products,, can give off poisonous gas if during the burning of this product.Foam polystyrene particle mainly threatens environment structure, and, suffer forbidding of increasing community.

Foam polystyrene particle also is dangerous to children and wild animal, and they usually think them by mistake food, and the result digests them.Foam polystyrene particle can not digest, and is the major cause of children's airway obstruction.

Also adopted other packing packing material, such as shredded paper.But shredded paper lies in the container usually, and, need very a large amount of shredded papers as the required discrete material of object in filling space and the protection container.For so a large amount of shredded paper is provided, usually cost is too high, and after the use, so a large amount of paper must be handled.And the cushioning ability of flat shredded paper is very little.

The US Patent of Johnny M.Parker " folding and beader ", the patent No. is 5,088,972, and has authorized on November 18th, 1992.It has disclosed the apparatus and method of a kind of packing that are used for being shaped, and this material can be eliminated some undesirable characteristic in those products discussed above.This apparatus and method are used for the slice bending and wrinkling binding, ornament materials and/or the loose packing with predetermined length that become of sheet material.This device generally includes an accessory device that is used for commercial paper-tear picture machine, with the sheet stock that is used to tear up.This device comprises a movably plate washer, and the slice of sheet material is when the cutting blade of paper-tear picture machine is extruded, and is pushed to be against on the block.Movably baffle plate can be controlled in fringe to be squeezed in the zone limited between baffle plate and cutting blade.Again other slice is filled in this limited space can make slice be crowded with other retaining walls of sheet material in the limited area and be compacted, bending and wrinkling.This makes the slice bending also self compress, and forms the one-tenth section fine sheet of pleated.

(the U.S. Patent application serial number (SN) is 538 to be entitled as " resilient packing product and the manufacturing installation thereof " that Johnng M.Parker submitted to June 14 nineteen ninety, 181), disclosed the improved method and apparatus that this resilient packing product is shaped, also disclosed about the desired characteristics of this resilient packing product and the further details of characteristics.The method of the Production and Packaging product that is wherein disclosed comprises the following steps: to send into one piece material at least along first direction; Two covers replace and stacked chopping disk is cut into many slices with this sheet material by rotating; Between two cover chopping disks, send into this sheet material; When at least one outside face of a corresponding chopping disk when first direction moves, by rotating this outside face, every slice is advanced; Limiting each slice no longer moves on along first direction; And, sequentially bend each slice by restriction working direction and opposite with this direction, and it comprises the device and the equipment of Production and Packaging product of being used for, and the packaging product of generation comprises the slice material of many narrow, elongations, and this product has natural elasticity.Each slice comprises that the horizontal kink of many opposing natural elasticities is to form the strip piece of vertical compression.

And according to the US Patent (patent No. 5,088,972) and the resilient packing product produced of the method that discloses in the U.S. Patent application (number of patent application serial number (SN) 538,181) with processing satisfactory, but it some very desired characteristics can not often reproduce simply or easily.In the invention that is disclosed main embodiment, adopted the tubular craft paper therein, with continuous production required, vertical slice by compression.Each vertical by compression slice comprises many laterally folded portions,, planar section is longitudinally arranged substantially therebetween.The repetition of this slice and controlled structural requirement folding part are shaped with the direction opposite with the paper natural elasticity.As in the U.S. Patent application (application Ser. No 538,181) clearly shown in, the original structure of these folding parts causes the longitudinal plane part contact fully basically of the every side in folding part.After each slice can " loosen ", the angle of each folding part under the natural bias effect of the paper wood of making slice, was tended to open between both sides, folding part longitudinal plane part.

Although to loosen a little be desirable to the angle at place, folding part between longitudinal plane part, the ability that the total value of this angle at each place, folding part and it keep being substantially the acute angle form subsequently influences the quality of packaging product really.In other words, preferable packaging product not only comprises the structure of this folding part, and it finally can be loose, and between the adjacent longitudinal plane part of the every side in folding part, forms an obtuse angle.The vertically bar by compression of this " loose " can not have some required elastic characteristic and in demand side cross-tie power.

The result, though the US Patent (patent No. 5,088,972) and U.S. Patent application (application Ser. No, 538,181) required packaging product has been produced in the invention that discloses in really, and it has said overall elasticity feature here, but needs method and apparatus to want can be used for guaranteeing or improve this packaging product with preferable technician.In this respect, the device of US Patent (patent No. 5,088,972) and U.S. Patent application (application Ser. No is 538,181) announcement is to be used for the many slices that are shaped by cutting mechanism are sent the resistibility change that has.This after chopping disk by the gross the variation of the resistibility in the limited area changed the power that vertically produces on the slice by compression at each really.

Yet, have been found that total temperature of manufacturing equipment tends to influence the quality of resilient packing product in producing this packing process.If humidity is lower, then the Resistance Value that produces in the exit of cutting mechanism will be higher, if and the humidity of this equipment is higher, it is one different from low value that the Resistance Value that produces need be adjusted to, so that attempt to produce the vertically identical desired characteristics of slice by compression with better resilient packing product again.

Disclosed in the US Patent (patent No. 1,680,203,2,668,573,2,679,887,2,786,399 and 3,150,576) and be used for making the method and apparatus that sheet is wrinkling substantially or bend.

US Patent (patent No. 1,680,203) relates to crape and the manufacturing method and apparatus thereof as product.The method and device be used for making its fabric no matter be do, wet and or would rather be the wetability product.Also comprise mechanism, it can be used to the feeding fabric but can influence the gathering situation of fabric (it has different relative pressuries and angle difference) different piece, extends and has different substantially but fabric wrinkle, wrinkle or the wave of predetermined density thereby produced along different directions relatively.

US Patent (patent No. 2,668,573) is used for making paper to form ripple.The invention that is wherein disclosed is adopted and is soaked to the material of an appropriate level, by feed rolls it is passed through a passage to produce ripple struction.This passage comprises two parallel surfaces, and they separate corresponding to the wave height of finishing.This passage comprises roller or the plate that is heated to suitable degree.By this way, the spine of the wave that obtains along hot surface or the top of ripple at first are dried, and perhaps we can say, and be forever constant.The ripple of Shi Xianing is very approaching by this way, and adjacent top or spine are in contact with one another or almost contact.

US Patent (patent No. 2,679,887) has disclosed the method to scribbling poly-vinyl resin in the past or giving a discount or crease with the paper of polyethylene foil lamination.Fabric process under the drum that extends to a water tank, water tank contains the water that is heated to proper temperature, so that make polyethylene pass through the water tank that it is regulated, it can become soft and flexible like this, but can significantly not be clamminess or lose its shape, maybe can flow.Except polyethylene being carried out temperature adjustment, compound fabric carries out temperature adjustment in common mode to paper through the passage of water tank so that discounting subsequently with becomes the ripple operation, the time that material is washed is so, consequently influences the temperature adjustment of paper.

US Patent (patent No. 2,786,399) is at the body manufacturing that is specially adapted to as that class wrinkle sheet stock of engine fuel filter component.In when operation, on the two slice principal directions through behind the roller, paper process under the nozzle, by nozzle, the air dried resin and plastic that is mixed with water is ejected into downwards on the surface of paper.When the paper process was creased mechanism, resin and plastic can be at room temperature dry.

Technology that US Patent (patent No. 3,150,576) discloses and device are used for forming various forms of transverse waves on ductile material sheet material or band.Preferable ductile material is a paper, and paper carries out pretreatment to material moving forward under the effect of inlet nozzle to, next suitable hydrothermal solution body source of nozzle and pressure such as linking to each other with vapour source before in the end being shaped between the herringbone structure.

US Patent (the patent No.: 1,680,203,2,679,887,2,768,399 and 3,150,567) disclosed a step, promptly before operating control, fold or creasing, the sheet shape material material has been applied steam, water or some other wetting agents.

Though the patent of above-mentioned discussion comprises the mechanism that is used for handling whole sheet material, and the US Patent (patent No. 2,045,498) slice that downcuts of the fabric of the Jie Shiing fabric that can be made of regenerated cellulose forms, it can be used for the deburring of cap and shoes, and, be used for knit goods.Single slice or band do not have intensity wiry and flexibility, and, can be handled with the reagent of softening formulation, hardness is reduced in the limited field that fabric can use.The riglet with required width that downcuts from the fabric of regenerated cellulose is harder, does not have elasticity, and, having N/R hardness, metal filament intensity is low.Slice self extrusion or crushing,, easily curved band uniformly soft to produce, these bands have bigger metal filament intensity by after dying machine (comprise bound axial cylindrical describe device) and being pulled through.Every slice deliver to dye machine before, scribble or be sprayed with lubricant such as paraffin or other wax.This processing helps to alleviate the latch up phenomenon when dying machine, simultaneously, when they when platform leads to labyrinth type or inner-rotary type platform, played the effect that reduces the parts friction force.

In the US Patent (patent No. 5,088,972) and before the folding and wrinkling device and method of the fringe that is used for sheet stock that is disclosed, US Patent (patent No. 2,621,567,2,686,466 and 2,770302) disclosed different device, they attempt to tear up can be as the paper of packing material type.In one way or another kind of mode, each in these devices is torn into paper or cut into slice, and in the place that separates on slice length, makes slice that kink be arranged, to produce common serration slice.Though kink or bight become the obtuse angle, and, do not resemble the US Patent (patent No. 5,088, that is disclosed 972) is shaped or generation like that securely, yet be apparent that: although the mode that these slices are shaped is not too effective, it still has this advantage of zigzag structure of doing firm and well.Although disclosed these devices in the above-mentioned patent, comprise and be commonly used to sheet material is carried out wrinkling, wrinkle or folding method and apparatus, broken about paper is torn up or shears with in these patents that form slice, do not propose water or other liquid and improved therefore and the product that is shaped.In fact, obviously can take into account: any this complexity stacked tears up dish or cut-off wheel can be by normal operation under the paper environment that soaks or under the environment in humidity.

Should be noted that: the preferable machine that discloses in US Patent (patent No. 5,088,972) comprises the zig-zag cutting blade.The zig-zag cutting blade is intended to promote easily to tear up sheet stock, in case and when helping sheet stock to bite cutting blade, sheet material can be drawn in shredding equipment.Yet, have been found that this zig-zag cutting blade of employing has increased the dust during required slice forming materials significantly.On the other hand, the structure of the preferable cut-off wheel that discloses in US Patent (application Ser. No 538,181) comprises smooth outside face, yet the material of preparing sheet stock is cut into the slice form in it " is caught " and held in this outside face meeting.Yet, on a large scale sheet stock is cut into a large amount of slices and has produced the dust that forms by minimum sheet stock.Though do not know also whether the dust that is made of little paper stock is by US Patent (patent No. 2,621,567,2,686,466 and No.2,770,301) device that is disclosed in produces during tearing up, but has recognized that, anyly cuts this material on a large scale and can form this dust granule.

On the other hand, compare with other device (they adopt a kind of diverse method so that produce bending or crooked on the slice of moulding), very possible is, this dust in U.S. Patent application (in the application order 538,181) forms bigger.Since adopt preferred approach and device, so that by limiting slice in the cutting part exit with the shaping slice, therefore, slice keeps for a long time in cutting zone, during this period, the other rotation rapidly of the slice that cut-off wheel is collected there.This rotation of cutting blade obviously produces friction thereon, and it makes the new side cut wearing and tearing that form of slice, thereby further produces grit.Obviously, have been found that the zig-zag cutting blade that adopts in the US Patent (patent No. 5,088,972) can significantly increase because the N/R amount of dust that the slice builder produces.

Some other patents comprise US Patent (patent No. 2,865,080,3,235,442 and 3,859,965), the device of announcement be used for carrying out various have some soak or the various ultimate fibres of wetting component or fiber so that its feature of general improvements.

Basically, be used for the being shaped preferred means 10 of packaging product comprises that one is used for from the feed section 12 of a large amount of scraps of paper 14 of a roller 16 supplies.In the paper industry, the installation of this big roller 16 and replacement method are well-known.In the preferred means 10 of shaping packaging product, roller 16 comprises the about 60 inches scraps of paper of transverse width 14.The scraps of paper 14 will then, be led, so that the three-ply paper material 100 to preferable machine 200 feedings to be provided again by three independent vertical fragments 30,32,34 of break into just as will be seen.As to be discussed below, machine 200 comprises that a feed section 202, cut length 204 and one discharge section 206.

In preferred means 10, the big scraps of paper 14 are walked around bottom deflector roll 60, through a wetting preferably system 20 from the lower guide of roller 16.The scraps of paper 14, from the stratification mechanism 22 of further upwards leading of wetting system 20, so that the scraps of paper 14 are vertically cut, and stratification.Stratification mechanism 22 comprises that two are vertically cut tool 24, and they are divided into the scraps of paper 14 three vertical fragments 30,32,34 basically.Vertically fragment 30,32,34 leads respectively again, around diagonal angle rod member 40,42,44.Again the guiding of fragment 30,32,34 causes stratification, so that the paper wood 100 of shaping combination layer.Paper wood 100 is directed to machine 200 then, so that the following packaging product of moulding.

Therefore, as described, preferred means 10 comprises those characteristics that can find usually in US Patent (patent No. 5,088,972) and U.S. Patent application (application Ser. No 538,181), but does not comprise wetting system 20.

As shown in Figures 2 and 3, preferable wetting system 20 comprises an elongate opening container 50, and this container extends the whole length of the scraps of paper 14 of process therefrom.Supply water continuously to container 50 from reserve tank 52, and reserve tank 52 has the charge pump 54 of a band joint supply pipeline 56.The water that adds container 50 can be by loop 58 overflows of the other end.As a result, new water can add container 50, and excessive water can be got back to reserve tank 52.

For the water in the container 50 is sent to the scraps of paper 14, the scraps of paper 14 at first are directed and around the lower guide roll 60 that is positioned at wetting system 20 lower area places.Tool 24 scraps of paper 14 of vertically cutting that lead to stratification mechanism 22 from deflector roll 60 are guided by dampener 62.Dampener 62 is mounted in the water that extends in the container 50, and is rotated with relevant transmission device 66 by motor 64.Transmission device 66 comprises that one is positioned at synchrodrive pulley and synchrodrive pulley that is positioned at lubricated roller 62 ends of electrical motor 64 outputs place, and a synchronous belt extends betwixt.Electrical motor 64 comprises speed-changing mechanism, and to adjust wetting 64 rotations along direction shown in the arrow, the scraps of paper 14 move therefrom.The rotation of dampener 62 precipitates the water in the container 60 on the face of cylinder, when it crosses on the face of cylinder of dampener 62, be sent to the scraps of paper 14 then.The actual position of dampener 62 can be adjusted by the motion of end fabricated section 68, and these fabricated sections 68 are shown among Fig. 2 and Fig. 3, but omit in Fig. 1.By the location adjusting bolt opposite with biasing spring 74 directions, end fabricated section 68 can rotate around pivot 70 with regulating.As a result, can regulate the water yield that is added on the scraps of paper 14 by two means.The increase of electrical motor 64 speed can cause dampener 62 to rotate sooner, so that transmit more water for the scraps of paper 14.In addition, selectively move, can apply bigger pressure to the scraps of paper 14, thereby can further guarantee water is directed on the scraps of paper 14, to increase its humidity through dampener 62 cylindrical surfaces by end fabricated section 68.

As shown in Figure 3, through the dampener 62 and wetting scraps of paper 14 upwards are directed to adjustable tool 24 of vertically cutting so that redirect around an anvil roll 80.Each is vertically cut tool and is installed in along on the rod member 62 of the scraps of paper 14 whole length extensions.Regulating mechanism 84 can be used to be increased in each and cuts pressure on the tool 24, can guarantee whole vertical cutting of the wetting scraps of paper 14.Each is vertically cut tool 24 and aims at urethane surface portion (not shown), to provide providing suitable supporting by the cutting action of vertically cutting tool 24 generations.

As a result, along with the scraps of paper 14 are wetting by the deposition of water, the vertical fragment 30,32,40 of each of paper is wetted before advancing to around diagonal angle rod member 40,42,44.When these fragments reconnect, with when machine 200 advances, they have formed three layers of wetting paper wood 100 preferably.

To shown in Figure 7, preferred embodiment of the present invention comprises and is used for being shaped preferable and through the machine 200 of improved packaging product as Fig. 4, it with U.S. Patent application (application Ser. No 538,181) in announcement similar.With the about 15 inches machine of width that discloses in the U.S. Patent application (application Ser. No 538,181), to compare, preferable machine 200 has been applicable to brings up to about 20 inches with width.Just as will be seen, other modification that preferable machine is carried out, so that various alternate configuration to be provided, and they are not within the scope of the invention.

Preferable machine 200 comprises feed section 202, cut length 204 and the section of drawing off 206.The structure of feed section 202 can be sent one or more scraps of paper material into cut length 204, vertically cuts.Then, the slice that cut length 204 is downcut is discharged into the section of drawing off 206 from cut length 204, and carries out drying.

In order to provide basic motive, a feed motor 208 is arranged in feed section 202 to machine 200.Feed motor 208 has a relevant reducing gear section 210, and its reducing gear output form is a driving chain wheel 212.In order to provide power to cut length 204, a cutting electrical motor 214 has relevant reducing gear section 216.The output form that subtracts whole gear segment 216 is a driving chain wheel 218.

In order to begin the operation of machine 200, the wetting paper wood 100 of the preferable packing that are used for being shaped is preferably supplied with from supplying with section 12, supplies with section 202 so that the paper wood that one or more layers is wetting 100 offers.As shown in Figure 9, material 100 is tentatively aimed at by two guiding rollers 219.Although unspecial repetition in Fig. 4 as mentioned above, three layers of wetting paper wood 100 preferably provide by supplying with section 12.

As shown in Figure 5, feed section 202 be configured to wetting paper wood 100 is vertically advanced along first direction A.First live roll 220 is fed into transverse cuts parts 222 with wetting paper wood 100.Transverse cuts parts 222 comprise the cutting blade 224 of four rotations, and cutting blade is installed in rotation on the axle 225.Supporting cylinder 226 is aimed at axle 225, and comprises poly-chloroprene rubber section 228, and they are used for aiming at and concerted action specially with cutting blade 224.

Although do not illustrate in the drawings, each preferable cutting blade 224 comprises that not only one is essentially the zigzag edge of a knife, also comprises several several gaps along its length, when passing through under it with the wetting paper wood 100 of box lunch, only it is carried out the part cutting.Since 100 partly cuttings of wetting paper wood, and stipulated the scraps of paper 238 that part links to each other with the remainder of paper wood 100, and it is sent to second live roll 230, so that further be directed to cut length 204.Advance to 222, one first bias voltage rollers 221 of transverse cuts parts and be biased to first live roll 220 and aim at it for wetting paper wood 100 and the scraps of paper 238 are remained on.The second bias voltage roller 231 is biased to second driven roller 230, and aims at it.

All first live rolls 220, supporting cylinder 226 and second live roll 230 rotate with same rotating speed.Each component width in the feed section 202 is more preferably greater than 20 inches, so that wetting paper wood 100 is provided to cut length 204, just as will be seen, cut length 204 also can be held 20 inches wide paper woods.First live roll 200 preferably has protrusion or coarse, so that when sending wetting paper wood 100 wherein, enough friction force are arranged, and second live roll 230 is preferably smooth.In addition, the diameter of second live roll 230 is a bit larger tham first live roll 220, so that wetting paper wood 100 is kept the state of tension, and carries out part cutting rightly by transverse cuts parts 222.Because the smooth surface of roller 230, not to be the scraps of paper 238 that will wetting paper wood 100 produce with the effect that only depends on live roll 220,230 tear or separate from remainder the other tension force that is produced by the second big slightly live roll 230 practically.

The mechanism that is used to provide 220 rotations of first live roll that comprises cutting bobbin 225, supporting cylinder 226 and second live roll 230 is shown among Fig. 4.Basic motive is provided by feed motor 208, and second live roll 230 comprises that one is installed in the driving chain wheel 232 of its end rigidly, is used for realizing from being in transmission connection between driving chain wheel 212 and the chain gearing 213.Gear 232a on the axle of second live roll 230 and first Sui on the side body that is installed in feed section 202 take turns 233 engagements, and make it to rotate.233 and gear 234 engagements of first Sui wheel itself, gear 234 links to each other with supporting cylinder 226.The gear 234 and second Sui take turns 236 and one than big gear wheel 239 engagements, and big gear wheel 239 is connected with the rotating shaft 225 of cutting blade 224.The diameter of gear 239 is twices of gear 234 diameters, so that axle 25 is with half the speed rotation of supporting cylinder 226.As a result, four cutting blades 224 are aimed at two poly-chloroprene rubber sections 228 of supporting cylinder 226 when rotating with corresponding friction speed.Transmission gear 237 engagements on second Sui wheel 6 and first live roll 220 ends, and make it rotation.Along with each sprocket wheel and gear rotate along the direction shown in the small arrow on Fig. 4 and Fig. 5, can see that the wetting paper wood 100 of multilayer will be dropped into to cut length 204 by feed section 202.

In the another kind structure, gear transmission can change, so that the diameter of supporting cylinder is bigger, like this, can comprise three poly-chloroprene rubber sections on it.Bigger supporting cylinder can make the entire machine width that bigger stability is arranged, and this is because wetting paper wood 328 when vertically advancing by feed section, carries out desirable transverse cuts by the cutting blade along wetting paper wood 328 horizontal expansions.

In preferable machine 200, feed motor 208 is speed changes, and the deceleration of its reducing gear section 210 is 10: 1.Electrical motor 208 preferably is set as with the wide about 20 inches wetting paper wood 100 of the about 360 feet speed feeding of per minute.Cutting blade 224 is spaced apart length along wetting paper wood 100 every 4.4 inches around axle 225, carries out the part cutting.Therefore, vertically drop into the preferable scraps of paper 238 of the wetting paper wood 100 of cut length, its width is 20 inches and length is 4.4 inches.

Cut length 204 comprises upper and lower group of stacked chopping disk 240,242 as shown in Fig. 4,5,6 and 7.Cut paper dish 240 is installed regularly, in case rotation on axle 241, and cutting disk 242 is installed regularly down, so that rotation on axle 243.Lower shaft 243 comprises a driving chain wheel (not shown), and is connected with the driving chain wheel 218 of cutting electrical motor 214 by chain 219a.Axle 241 is connected with the 243 gear (not shown)s by coupling, so that rotate accordingly in opposite direction along direction shown in the arrow B substantially.The stacked of dish 240 and 242 is like this with being meshing with each other, so that its separately the adjacent chopping disk 240 and 242 of axle on 241 and 243 be spaced from each other, so that therebetween receive every scraps of paper 238 of wetting paper wood 100 at other chopping disk 242 and 240 on 243 and 241 from feed section 202, no matter be one deck or multilayer.In case the scraps of paper 238 that are directed between chopping disk 240 and 242 cut into wetting slice along direction A end wise, and each slice comprises the number of plies of original scraps of paper 238 respective number of being supplied with feed section 202.

Usually, the cutting scraps of paper 238 in case form relevant with each chopping disk 240 and 242, extend wetting slice.Between the sides adjacent edge of a knife of the side tool mouth of each chopping disk 240 and adjacent chopping disk 242, cut.Generally keep aiming at by chopping disk 240 and the 242 wetting slices that produce, so that pass through cut length 204 by one group of one group of rippling device relevant 244 with chopping disk 240 and 242.

Each rippling device 244 comprises that one is used for receiving corresponding axis 241 by therebetween and 243 central opening 245.Corresponding chopping disk 242 and 240 side direction or lateral alignment on rippling device on one 241 and 243 and other 243 and 241.Each rippling device 244 is installed on the transverse bar member 246 and by 246 supportings, rod member 246 is crossed cut length 204, and by the corresponding aperture in rippling device 244 ends.Though supported by rod member 246, preferable rippling device 244 can along axle 241 and 243, carry out limited motion with chopping disk 240 mode identical with 242.

The most significantly, each rippling device 244 comprises an end face 248, and end face 248 is aimed at the corresponding chopping disk 240 and 242 on the rotary-inversion axis 241 and 242 mutually.Chopping disk 240 and 242 and the structure of the end face 248 aimed at of rippling device 244 has formed a total zone, this zone be used for when the scraps of paper 238 through wherein the time, by the restricted motion of the wetting slice of cut length 204 generations.The end face of aiming at 248 draws off each rippling device 244 of side in cut length 204 extension 250 places stop.The purpose of extension 250 will be discussed below.

Cut length 204 provides power by the electrical motor 214 of band variable-speed controller, and, comprise reducing gear 216 with 6: 1 reduction ratios.Each cut length 240 and 242 wide about 1/8 inch.Therefore, each cutting axis 241 and 243 comprises at least 80 chopping disks 240 and 242 thereon so that provide at least 160 chopping disks 240,242 to two groups so that by required, to wide be that 20 inches the scraps of paper 238 cut.Best, the speed of electrical motor 214 is regulated, so that the speed of the exterior cylindrical surfaces of each chopping disk 240,242 is per minute about 380 feet.In other words, chopping disk 240,242 is to rotate than second driven roller, 230 fast linear speeds.The result, chopping disk 240,242 fast speeds make them to catch the scraps of paper 238 when the scraps of paper 238 enter therebetween, leave behind thereby make every scraps of paper 238 follow the adjacent scraps of paper 238 from it, so that the scraps of paper of partly cutting 238 separately, so that paper is advanced by cut length 204.As shown in Figure 5, separate as yet and do not take place, and tend to be about to when second driven roller 230 leaves, taking place at the scraps of paper 238.Needed for driven roller 230 is to keep in touch with the adjacent scraps of paper of following 238, so that keep the tension force on the material, to carry out transverse cuts.As a result, no matter whether every scraps of paper 238 have the wetting paper wood of single or multiple lift 100, all will longitudinally cut into wetting slice in cut length 240 before next scraps of paper that provide 238 enters cutting 204.

From top discussion, should be understood that preferable machine 200 also must comprise some mechanisms, they are used for limiting its motion at wetting slice after cut length 204 internal shapings.Therefore, the section of drawing off 206 is aimed at cut length 204, and, comprise that mainly one draws off groove 260.Draw off groove 260 and be held in place by framework 258, framework 258 is fixed on the both sides of cutting 204.The preferable groove 260 that draws off is mainly made by Plexiglas's or some other durable transparent plastic materials.

Draw off the upper wall 264 that groove 260 comprises a lower wall 262, two sidewalls 266 are arranged therebetween.Draw off groove 260 in order to support generally, a pair of bottom bracket 268 has been fixed on the framework 258, can receive and support lower wall 262 thereon.The leading end of each sidewall 266 is fixed between lower wall 262 and the upper wall 264 by bolt mechanism 276 movably.For lower wall 262 and upper wall 264 are exerted pressure, so that fully sidewall 266 is remained on therebetween,, adjustable carriage mechanism is arranged, on upper wall 264, to produce downward power at the top of framework 258.Specifically, carriage 270 is crossed the end face of upper wall 264 and is extended, and is held in place by adjustable bolt mechanism 274, and bolt mechanism 274 is extended by the rigid bar 272 that is fixed between the body side frame 258.Basically, bolt mechanism 274 attempts come upper wall 264 and lower wall 262 are applied the pressure that strengthens usefulness by carriage 270, simultaneously, also on the upper and lower surface of sidewall 266, provide big friction force.

Can be regulated than the preferable groove 260 that draws off when understanding, so as when the wetting slice of shaping when cut length 204 draws off, hold the scraps of paper of wetting paper wood with different in width, then this mechanism of exerting pressure of oppose side wall 266 is just significant.In other words, as shown in Figure 6, the section of drawing off 206 is intended to receive the slice that the scraps of paper by wide about 20 inches wetting paper wood are shaped.Yet feed section 202 and cut length 204 can reasonably be held and be too narrow to about 15 inches scraps of paper.Among the embodiment that discloses in the U.S. Patent application (application Ser. No 538,181), the width that draws off groove is narrower, and these are because it wants to be used for the narrower scraps of paper of feeding.Whole structure is identical with the groove 260 that adapts to broad, just be modified as can with increase because of volume and face area produce more energetically.

For providing suitable drawing off, can regulate this preferable groove 260, so that the wetting slice to drawing off from cut length 204 provides enough resistances to the section of drawing off 206.For in the section of drawing off 206, increasing resistance, by bolt mechanism 276 sidewall 266 is installed, the tail end of each sidewall 266 is rotated, have narrow profile so that draw off groove 260.Specifically,, then bolt 274 can be unscrewed, to reduce the pressure between the carriage 268 and 270 if the structure of sidewall 266 is fit to the scraps of paper of narrower wetting paper wood.Along with the power on upper wall 264 and the lower wall 262 reduces, each sidewall 266 can rotate around bolt mechanism 276 separately.In order suitably to regulate sidewall 266, each framework 258 has adjustable bolt mechanism 278, so that sidewall 266 controlledly locate, and dependence bolt mechanism 276.Although the sidewall that shows among Fig. 6 266 is parallel, to hold the scraps of paper of wide about 20 inches wetting paper wood,, can inwardly regulate bolt 278 if the scraps of paper of wetting paper wood are too narrow to 15 inches, significantly narrow to about 15 inches so that draw off the tail end of groove 260.The narrow profile that produces can produce the volume of minimizing, so that wetting slice is collected within it, and, with to carrying out very big restriction by all wetting slices that wherein draw off.

Wetting slice can further be limited by at its exit end place adjustment doors 280 being set through drawing off groove 260.Door 280 cooperates with upper wall 264 usefulness hinges.The carriage 282 at door 280 two ends can be used for manually or the automatic controls (not shown), suitably locatees with opposite house 280.As mentioned above, control packaging product quantity-produced door 280 of the present invention needn't always be in position closed and restriction.In other words, in case door 280 is closed packaging product enough is collected in the inside that draws off groove 260, because packaging product can be enough to produce appropriate restriction in the source of unloading of cut length 204 by the total frictional force that draws off groove 260 generations, so that the required feature that will describe below producing in slice.

In a kind of structure of preferable machine, the internal height H that draws off groove 260 is about 2 inches, and inner width W can change between about 15 and 20 inches.Owing to draw off the immense pressure and the power that produce in the groove 260, lower wall 262 and upper wall 264 thick about 3/4 inch, and each sidewall 266 thick about 1-1/2 inch.And about 12 inches of the preferred length that draws off groove, this length can be selected according to producing the used material type of preferable packaging product.2 inches height makes the extension 250 of each rippling device 244 can loosely be positioned at the inside of groove 260, so that produce from cut length 204 to the section of drawing off 206 preferable transmission.

Can regulate inner width according to the scraps of paper size that is provided though draw off the structure of groove 260, should be noted that: if machine attempt is used for the identical scraps of paper of acceptance width continuously, then different simplified construction also can add employing.Such as, the whole groove that draws off can be formed by rigidity and firm bonded assembly roof, diapire and sidewall.In addition, this diapire that draws off groove can be downward-sloping from this central region that draws off groove, so that when the packing of making draw off from drawing off the groove end, help its transmission.

Shown in Fig. 4,5 and 6, be the preferred embodiment of form with machine 200, do not comprise expression symbol by the packaging product of its shaping.Yet the part of Fig. 7 is amplified diagrammatic sketch and is comprised that one represents symbol at cut length 204 in-to-ins.Should understand, preferable machine 200 is produced the wetting in groups slice that packs tightly fully, they be substantially included in expansions, loose with draw off groove 260 and mix preceding mutually and at the preferable packaging product that leaves after drawing off groove 260.Many mixing tightly mutually and packaging product that the slices of interconnection produce is with form closely so that make the actual orientation and the structure of the various wetting slices that cut length 204 and the section of drawing off 206 are interior differentiated become very difficult.Yet, in scheme drawing 7,8 and 9, can best understanding be arranged to the representative of the packaging product that forms in by machine 200.

Usually, should admit: the wetting paper wood of the preferable packaging product that is used for being shaped has the natural elasticity that is easy to bend resistance.No matter the sheet shape material material is paper, cardboard, mylar or any other material, and this material typically tends to keep and anti-any bending with the form of stretching.As long as take Xiao Zhang's paper simply, and attempt it is converted into half, just can easily observe this principle.If people attempt to be exerted pressure in the bending place, so that stay the bending record on material piece, then when the two halves of paper trended towards nature and separate, bending place " loose " was N/R, and this is because original " record " tends to bend resistance in the paper.If which floor paper is bending simultaneously also, also can be observed same principle.

Though this condition obviously is suitable for dry paper, have been found that: lubricated paper trends towards reacting in essentially identical mode, but the degree difference.In other words,, then need less power, kink is begun to exert pressure, wetting paper wood is applied a bending record if paper is wet slightly.In addition, original " record " makes two halves paper be tending towards nature when separately kink is loose in because of paper, degree of separation than dried paper produce little.In addition, because degree of separation is little, it is more stable that kink is tending towards, and, when paper is dry, in the same time, to compare with the kink that more dried paper wood forms, the angle at its kink place is littler.

Though the present invention includes to mechanism that paper wood provides water so that humidity to be provided, should remember: the natural temperature of production site can comprise in the air and paper wood in some moisture content.As a result, the overall humidity at equipment place can produce the packaging product with preferable feature, and perhaps on the other hand, the packaging product that can cause having less required feature has a negative impact.Though be clear that: adjustment doors 280 can influence by the forming and feature of the slice inner fold of preferable production of machinery, obviously, wetting paper wood can make required feature easier, obtain more simply.And the mechanism of the amount of moisture in the adjusting paper wood can make things convenient in distinct device and produce required sheet package product reliably again, even distinct device may have the different humidity condition.

Remaining below all are noted that each kink that produces in describing in preferable slice, very tight when beginning at least, like this, the adjacent longitudinal component of wetting slice trends towards closed contact.Yet just as will be seen, when the pressure on each slice is loose, kink will have expansion or loose natural tendency, thereby the part bevel ground of adjacent kink is separated.

As shown in Figure 7, when the wetting scraps of paper 238 carry out between chopping disk 240,242, at its side knife-edge part, preliminary cutting, to form preliminary wetting slice 300a, slice 300a trends towards keeping flat along the smooth outer cylinder surface 240c and the 242c of each chopping disk 240 and 242.Preliminary wetting slice 300a is advanced to the skidding that draws off of cut length 204 by plane of revolution 240c and 242c at least in part.

Yet, be collected in the section of drawing off 206 by the wetting slice that will be shaped in advance, can provide big resistance to wetting each slice 300a of preliminarily forming, this is discussed below.At first, should understand fully: many slices that are shaped in advance closely are collected in the side that draws off of cut length 204.The result, when each initial wetting slice 300a that is shaped applies chopping disk 240,242 effects of friction force by each, and when advancing by cut length 204, the resistance of its end bends the slice 300a of preliminarily forming successively, so that slice 300b by compression to be provided vertically.By in being shaped in advance of drawing off that side collects and by compression slice 300b fully longitudinally, the vertically original just formation in cut length 204 of slice 300b by compression.

The machine 200 that can not stop, and check zone near chopping disk 240,242, with the slice of observing compression fully longitudinally at chopping disk 240,242 with curry definite position between the mechanism 244.Yet be contemplated that: they will trend towards concentrating in the axle 241,243 side that draws off of connecting line in the heart.The wetting slice 300a that might begin to take shape as a result, will be than weak point shown in Figure 7.When each wetting slice longitudinally cut, each wetting slice can bend in proper order in beginning.Yet, because all cuttings 240,242 are rotated to drawing off side, seemingly will tend to make them to concentrate, rather than concentrate to the connecting line of cut length 204 to the side that draws off of cut length 204 at each friction force that fully longitudinally produces on by compression the slice 300b.

By compression the slice 300b fully longitudinally that motion is concentrated is held in place, so that drawn off by the aligning end face 248 of each rippling device 244 and extension 250.As mentioned above, Fig. 7 represents to understand best the vertical fully collection type of slice 300b in the cut length 204 that draws off the side place by compression.Though when the slice 300b that forms fully vertically by compression, outer cylinder surface 240c, 242c apply some compressive forces to each initial slice 300a really, also be understood that: side surface 240s, the 242s of each chopping disk 240,242 also after shaping reaches, applies side-friction force to each vertical fully slice 300b by compression.

Should be pointed out that the middle embodiment difference that discloses of preferable machine 200 and US Patent (patent No. 5,088,972), this is because it comprises smooth cylindrical outer surface 240c, the 242c of chopping disk 240 and 242.Chopping disk in the US Patent (patent No. 5,088,972) comprises zig-zag or toothed structure, and it can catch material, and can guarantee material is carried out appropriate vertical cutting, with the shaping slice.Yet, have been found that: characteristics of the device that discloses in the US Patent (patent No. 5,085,972) are by smooth exterior cylindrical surfaces 240c, 242c, and be improved, this is because the type that various slices longitudinally are compacted in the cut length 204 of machine 200.Smooth exterior cylindrical surfaces 240c, 242c do not trend towards material being torn or wearing and tearing, and, significantly reduce generation dust or other fine grain possibility.And, as shown in Figure 7, along with by compression slice 300b is fully longitudinally closely collected at the outlet side of chopping disk 240,242, the smooth edge of chopping disk outside face can concentrate in advance, fully longitudinally by by compression the slice 300b, rotate, and can not tear along side direction egregiously, and this will produce a large amount of grits significantly.

Be noted that now since total power that the rotation of chopping disk 240,242 provides so that produce fully vertically by compression slice 300b, this power also continues each wetting slice that is shaped is in advance applied power, moves along the direction towards the section of drawing off 206 making it.According to the quantity of material thickness of being produced and kink, usually, by compression only about 1/2 inch-Yue 1 inch of slice 300b length in cut length 204 fully longitudinally of making by 4.4 inches wetting slices.

From above-mentioned, be noted that: before the present invention, people can't accurately determine by inserting wetting paper wood, this tear up or cutting machine in, what can take place on earth.Perhaps, people can expect: a large amount of this paper under the wetting conditions can damage chopping disk, even may not cut effectively.On the contrary, use the present invention, have been found that the scraps of paper of wetting paper wood can be cut effectively by chopping disk, and general, from its other advancing, to form required slice by compression.In addition, though in prior art, carry out general large-scale cutting process by the shredder of preferable cut length 201 or any other type, during with the shaping slice, can meet some grits, have been found that: wetting paper wood generally can reduce the quantity of the grit of generation.Usually feel: the additional moisture content of paper wood tends to provide some lubricated during the cutting of the edge of a knife, and, when the neighbouring surface process slice next door of chopping disk, can prevent further wearing and tearing.

As shown in Figure 8, according to possible optimal viewing, as if when closely longitudinally by compression slice 300c advanced by drawing off groove 260, wetting slice was concentrated near drawing off groove 260 arrival ends with the form of certain wave.Though by compression the limited tight kink of slice 300c is not longitudinally closely expected: its kink can resemble by compression the kink of slice 300b fully longitudinally that begins to take shape in cut length 204 tight.Significantly, the meeting that produces in drawing off groove 260 bends each preliminary wetting slice 300a successively, and this power can be than bigger along the several sections place, back that draws off groove 260 in cut length 204.The limiting force that draws off side of cut length 206 is than bigger along the limiting force of the other position that draws off groove 260, and this is because various slices draw off the additional function of the friction drag that produces when the inside face of groove 260 slides on the edge.Therefore, Fig. 8 only represents schematically what can take place to draw off groove 260 entrance points, and the wave possibility is inhomogeneous or locate inhomogeneous.Yet, slice 300c should be still longitudinally by compression very tight, but can not resemble fully vertically by compression the slice 300b tight.This vertically less by compression trend meets fully and is used for being shaped the elastic performance of the material of (comprising basic packaging product) slice.

About vertical fully slice 300b and closely vertically expression of slice 300c by compression by compression, no matter slice is that do or wet, all similar among Fig. 7 and Fig. 8.Owing to can not accurately check the inside that draws off groove 260 imports, hope can schematically be expressed and do or wet slice.In addition, should be pointed out that about the same problem of accurately checking that cut length 204 is inner and drawing off groove 260 imports can hinder accurately definite moistening slice and begin time to all dry.People expection: wetting slice can keep wetting a period of time in drawing off groove 360, and vertically by compression slice will be dry when the end draws off many.In fact, though during the scraps of paper 238 to wetting paper wood 100 carry out initial cut, it is wetting that material will keep, to reduce the formation of class dirt, yet, longitudinally cut effectively, with many slices that are shaped, and can begin to reduce moisture content in each slice significantly, and beginning dry run by the actual compression that 240,242 pairs of every slices of chopping disk carry out.Obviously, sidepiece and cylindrical edge place drawing off groove inside and each chopping disk 240,242 can produce significant friction.Therefore owing to, produce friction the unloading outlet and draw off in the groove 260 of cut length 204, each slice move through draw off groove 260 during, dry run can take place.

As mentioned above, can also should be noted that under the condition of the less generation of N/R dust material though believe wetting paper wood: the wetting conditions of paper wood also permits and makes little edge particle, when slice trends towards drying, links again with the remainder of slice.As a result, wetting slice should cause formed grit less, and, begin drying and shift to when drawing off groove 260 outlet at single slice by compression, make in packing the seizure grit also seldom.

As shown in Figure 9, in drawing off groove 260, leave cut length 204 certain position far away, comprise a combined group vertically by compression less slice 300d.And, vertically by compression less slice 300d will be further dry, and, compare with the slice of cut length 204 interior preliminarily formings, moisture is less.When vertically by compression the pressure on the less slice 300d when tending to descend because draw off the opening that draws off the end place of groove 260, the natural elasticity of each slice is tending towards making their expansions also to reset at relatively drawing off in the groove 260.Slice is when drawing off the end of groove 260, and slice 300d volume expanded is very big, and all vertically less by compression slice 300d mix fully mutually and reset.

According to Fig. 7,8 and 9 description, be noted that: the required basic power of slice by compression is shaped vertically, by making the previous vertical resistance of slice by compression that is shaped of chopping disk 240,242 opposings, and rotation produces, and draws off groove 260 and these previous slices that form trend towards concentrating on total length.Each vertically by compression natural elasticity of slice make them when drawing off groove 260 ends and advance, expansion longitudinally usually, and in case from drawing off that groove 260 discharges and when entering a container (not shown), every slice will further be expanded.As a result, be noted that now preferable machine 200 not merely comprises shredder structure, the shaping slice is concentrated, and it is compressed, to form packaging product.On the contrary, preferable packaging product is made up of many single vertical slices by compression, they tend to expand with mutual friendship knot and elastomeric mode, so that the final packaging product that produces with single slice have natural elasticity and, trend towards vertical expansion and tend to anti-transverse force or side force.

The typical case of the paper wood 100 of prior art that shown in Figure 10 is is slice by compression vertically.Overall slice material 300 by compression is relevant with all slices that formed by the prior art process dissimilar.Obviously, other this slice has different general acute angles between the adjacent plane part, and these planar sections have different length.Yet the slice of paper wood 300 is representative types, also comprises some characteristic features, its objective is relatively by using vertically slice material 400 by compression of the similar typical case that is shaped by preferred approach of the present invention and device.Therefore, the slice material 300 when the schedule time first time after drawing off groove and emitting at the kink place, has a typical angle R.

As shown in Figure 11, after the time of additional predetermined several hours of process or a couple of days, same slice material 300 can be loose again, and usually can be at bigger acute angle S of kink place expansion.

From Figure 12 as seen, the vertical slice material 400 by compression of a kind of similar preferable typical case is to be shaped by preferred approach of the present invention and device, and length that it has and the adjacent plane part between the kink are similar.Yet, owing to when being shaped, moisture content is introduced material, the slice material 300 of the schedule time after the shaping and Figure 10 identical, the angle T at kink place is littler than the respective angles R of slice material 300.As what point out, have been found that: will make the 400 easier bendings of final slice material to moisture content being introduced paper material, and trend towards comprising that the angle at kink place is less.

And, as shown in Figure 13, after the same extra schedule time through several hours or one, two day, 400 expansions of slice material will be so, so that the angle U at kink place will be less than the angle S at the kink place of the comparable prior art slice material 300 shown in Figure 11.

Be to be understood that: prior art and preferable packaging product of the present invention all comprise this slice material of many mutual friendship knots, and it still has the trend that continues expansion.Therefore, the slice material 300 and 400 shown in Figure 11 and Figure 13 is removed from the many similar slice of mutual friendship knot basically, so that confirm following trend, that is, can fully expand when the resistance that produces because do not hand over knot with extra this slice.

Yet, should be understood that: adopt method and apparatus of the present invention can produce tighter by compression slice material 400 longitudinally, and slice material 400 is As time goes on, can trend towards keeping angle at kink.Preferred approach of the present invention and device make at the vertical shaping of slice material by compression, can control, and the wetting conditions of tube apparatus not, under this condition, they are formed, to guarantee the quality of described slice material.Though wish significantly can separate, guarantee that importantly the acute angle of kink is enough little, with trend that keeps vertical expansion and the trend of resisting horizontal or side force in the adjacent plane part at the every side of slice material kink place.Obviously, if the angle at kink place can be expanded to another acute angle, Kuo Zhang ability drop then, and opposing laterally or the ability of side force be very limited.

Obviously, if people will check the prior art packaging product, perhaps with the single slice material in the packaging product of preferred approach of the present invention and device formed thereby, the single length of the adjacent plane part at the every side of then different kinks place is with difference.Yet people feel: representational slice material 300 and 400 has confirmed relative characteristic, and they can offer the slice material of preferred approach of the present invention and device shaping.
