Abstract
An improved roll product is proposed in which a long strip of film or sheet is wound on a core without using a conventional paper tube. The core used can be discarded without difficulty. The core is formed by bending a flat board of cardboard into a cylindrical shape. The side edges of the flat board may be spaced apart, butted together or overlapped. The side edges may or may not be joined together. The end of the film gets caught between the side edges of the flat board. This arrangement allows the film wound to be used up to the last inch while applying a tension thereto and without breakage of the core or winding displacement. A cap may be fitted into both ends of the core to increase the shape retainability of the core.
Description
Technical field
The present invention relates to a kind of tube-like piece that forms around flat paperboard rather than paper tube around coil packing with tensioning plastic sheeting, packaging for foodstuff plastic sheeting, or the Wound product of the sheet plastic used of packing container and the method for producing Wound product.
Background technology
Wrapping plastic sheeting or thin plate, for example be used for preventing that article from being that 300mm to 500mm is wide at tensioning plastic sheeting and the packaging for foodstuff plastic sheeting that packing chest damages, length is generally hundreds of rice, therefore, for with it around being rolled into Wound product, adopt usually to have high-intensity paper tube as the volume core.
In the office of this Wound product of a large amount of uses, pile up like a mountain for used paper tube.Because these paper tubes have very big intensity, around volume the time, can not fracture, also can not trample on pin.Therefore, these paper tube stacking volumes are big, are difficult to scrap, and are not easy to reclaim use.
In order to address this problem, the product that does not have the volume core is adopted in suggestion, increasing around volume density around winding off initial portion, namely in Wound product radial center part, takes up plastic foil by high density and produces Wound product as the volume core.
For this nothing volume core Wound product,, therefore can not be used at last around the volume film by each layer of the plastic sheeting close contact around volume in the high-density center part.Make this part film become waste product like this.And when approaching the terminal point that uses, the shape retention of Wound product own degenerates, and therefore the work when the tension plastic foil centers on an article parcel just seems very difficult.
In addition, if around the volume stretched film, because stretched film generally is the polyolefin resin, the about 18 μ m of thickness, width 500mm carries out around volume when applying the tension force of 5-8 kg/m, produces very big residual stress around the plastic foil that twists on the mandrel.Therefore, in the stacking process behind volume, volume core itself, can produce around the volume displacement on the axial direction of volume core if perhaps it is placed under the high temperature for a long time owing to thrust is destroyed, and has reduced its commercial value.
Summary of the invention
Target of the present invention provides a Wound product that does not use paper tube as its volume core, make it handle used volume core like a dream, long band thin plate or the film that rolls can be used last inch, not produce waste, and can not make the volume core produce compression failure or around the volume distortion.
In the Wound product of the present invention, long band thin plate or film are around twisting on its volume core, and the volume core is to form through cylindric bending with flat cardboard, and the material of this volume core is for can revert to flat board after use.
By with sheet paper through the cylindric volume core that curves, it can revert to flat cardboard state after use, and therefore can not resemble big volume the common paper tube, and be easy to scrap or reclaim use.
And as the raw material of sheet paper, by selecting the material of desirable strength and rigidity, and owing to bend to cardboard cylindraceous and have at thin plate or film around the required shape conservation degree of volume core of volume, therefore can use at last around thin plate or the film of volume.
The volume core can form by the flat cardboard two ends docking with bending.
With adhesive agent or adhesive tape flat cardboard two ends are docked, the shape conservation degree of volume core will further be improved.
The gap that the volume core can also provide by the sheet paper two edges of bending forms.
The volume core that the gap that provides by the sheet paper two edges forms needs to enter gap, sheet paper two edges around thin plate or the film of volume.By inserting thin plate or film, prevented the circumferential displacement at two ends.Behind volume, pull out that the volume core keeps cylindrical shape in the process of thin plate or film, can prevent that like this its internal diameter from reducing.So that around the thin plate of volume or film until use and at the end can both keep shape, and, in the situation that applies certain tension force, can use last always.
The volume core can form by the flat cardboard both sides of bending are docked mutually.
During by the flat cardboard of mutual docking both sides, even both sides do not use binding agent or similar thing to stick together, can not slide each other in flat cardboard two edges yet.Like this, behind volume, pull out that the volume core still keeps cylindrical shape in the process of thin plate or film, and can prevent that its internal diameter from reducing.
Can also carry out around volume by means of the volume core that thin plate or film end is meshed between the dull and stereotyped two ends of cylindrical bend, forming.
By the volume core of between the flat cardboard two ends of cylindrical bend the end of thin plate or film being nipped, the thin plate of insertion or film will play the sliding damper effect, thereby prevent to roll up the circumferential displacement of core.Pulling out in thin plate or the thin-film process behind volume, the volume core can keep cylindric, and its internal diameter does not dwindle, and it is in the axial direction mobile to prevent from rolling up core.
In addition, by inserting thin plate or film, because the frictional force effect of its end, even flat cardboard and do not use on the fixing volume of the material core of binding agent one class around the reel of volume machine, thin plate or film can not skid around volume the time yet.
When flat cardboard is carried out cylindrical bend,, can thin plate or film end be stung into volume core by both sides no matter whether gapped or whether both sides are overlapping between both sides.
Flat cardboard is preferably hardboard paper.
In general, paper sheet thickness is more big, and its rigidity is just more big.Like this, if use hardboard as flat board, can reach the required shape conservation degree of volume core, and after use, be easy to revert to sheet paper, so just be easy to scrap and reclaim use.
The volume core can use two or more than two sheet paper to make by around the reel around the volume machine cardboard being put on another piece.
If the film around volume is stretched film, in licking journey, preferably using limited tension force to carry out around volume, forming the degree of depth on the whole width so in the axial direction and be the opening more than the 10mm in the stretched film volume of volume, is below the 5mm because the opening that the residual stress in the stretched film produces is widened width.
When around volume during stretched film, reduce the residual tensions of stretched film by restriction around volume tension force as far as possible, opening is widened width below 5mm like this, thus can prevent stretched film around furling contracting and around volume displacement and the axial displacement of behind volume, rolling up core.There is no need like this to use the high strength volume core that resembles traditional paper tube, and, place at high temperature even Wound product is long-term, can not produce around the volume displacement yet.
Each block with assembled portion and flange portion preferably is assemblied in the two ends of rolling up core.
In this device, by the assembled portion of the block that disposes, the volume core is radially limited at two ends, improved like this conservation degree of shape, even the width of thin plate or film increases, pulling out in the process at thin plate or film behind volume, can prevent that rolling up in-core directly reduces.
Owing to also be subjected to axial upper cap flange portion restriction at two ends volume core, in pulling out thin plate or thin-film process, can prevent from reliably rolling up core from around the thin plate of rolling up or film roll, pulling out.
Moreover, when the transportation Wound product, even an end in contact terrace surface of Wound product because it is not the direct contact terrace surface, can prevent damage of product.
The volume core two ends preferably stretch out around the volume with overlapping thin plate or film two ends.
In this device, block is easy to be assemblied on the volume core.Therefore in addition, in general, because the flange portion of block does not contact thin plate or film end face around volume, pull out in the use procedure at thin plate or film, thin plate or film end do not contact the flange portion of block, can thin plate not occur or film is pulled out fault.

The specific embodiment
To introduce concrete device of the present invention with reference to the accompanying drawings below.
Fig. 1 and Fig. 2 are for embodying Wound product 1 of the present invention.Just as shown in Figure 3 and Figure 4, Wound product 1 be with long band sheet plastic or film 4 around twist in by with flat cardboard 2 bendings of millboard, roll, forming between the lateral edges on the volume core in gap 3, the inboard of inserting through the cardboard 2 of bending by gap 3 thus with its end 4a.
Just as shown in Figure 3 and Figure 4, when beginning to move into Wound product 1, be placed in around being placed on the outer garden perimeter surface of volume machine reel 5 by volume thin plate or film 4 tapered end 4a on the volume machine reel 6., have the flat board of the millboard of length B, around between when volume lateral edges gap 3 is being arranged, in thin plate or film 4 inboards, provide slight curving end, can contact the outer periphery of reel 5 like this around reel 5 thereafter.
Under this state, when the rotating shaft 7 of reel 5 rotated in the direction of arrows, as shown in Figure 5, flat cardboard 2 was along the bending of reel neighboring, and to form volume core 2a, thin plate or film 4 are simultaneously along rolling up core 2a outer surface around volume.Just as shown in Figure 6 and Figure 7, snap in by the gap between the lateral edges of flat cardboard 23 in the end of thin plate or film 4 under the situation of inboard of flat cardboard 2, thin plate or film 4 twist on the core 2a by reel 5 and the speed between the spool through regulating, and can not produce unnecessary tension force so in the above.
So just obtained a long band sheet plastic or film roll 1, as depicted in figs. 1 and 2, it is in the situation of not using the common paper reel, and the flat board by crooked millboard can form volume core 2a.Volume core 2a can revert to flat board after using.
Except to the such paper material of millboard, as flat cardboard 2, can use synthetic resin thin plates such as resembling polyethylene or polypropylene.
Device of the present invention has said structure, will introduce its operation conditions below:
As described above, for volume core 2a, owing to selected to revert to dull and stereotyped material, such as millboard, it does not resemble large volume the common paper tube, and is easy to scrap or reclaim.In addition, paper is more thick, and its rigidity is also just more high.If millboard is used as flat board 2, can obtain to resemble the desired shape conservation degree of volume core.
After dull and stereotyped inboard was inserted by the gap between the two edges of flat cardboard 23 in the end of thin plate or film 4, the thin plate or the film that are placed in the gap 3 can be used as sliding damper.Like this, two edges will can not slide over each other, even two edges are also like this when not being bonded together with binding agent.Like this, can keep drum.Therefore, when using thin plate or film by uncoiling, volume core 2a will be can be destroyed or shrink.It can also prevent to roll up the longitudinal travel of core 2a.This is applying in the situation of some tension, long band film or the thin plate of spooling can be used last inch.
Just as shown in Figure 3 and Figure 4, the end of thin plate or film 4 only needs be positioned on by the end 4a with film or thin plate 4 outside of reel 5, simultaneously with the inboard of flat cardboard 2 feeding thin plates or film, with the outer side contacts of reel 5 and the axle 7 of rotating drum, may be stuck on the cylinder of volume core 2a.Slide damper by the film end that is blocked is realized can no longer need the side of flat board is connected together, and does not need the end 4a of film 4 is fastened on the volume core 2a.This just simplified Wound product around volume work.
The end 4a of film 4 does not need to resemble and does into a cone shape shown in Figure 3, but straight.
Fig. 8 A and Fig. 8 B are the Wound product 1a of another device, and the length B of its flat cardboard 2 is longer than the device among Fig. 3, and like this, its side will overlap mutually, and the end 4a of film 4 sticks into dull and stereotyped 2 inboard by overlap.
In this device, be stuck in the sliding damper that the end 4a of the film 4 of overlap realizes, can prevent dull and stereotyped 2 lateral slips, prevent to roll up core 2a and shrink and prevent to roll up core 2 longitudinal travels.Applying in the situation of suitable tension like this, film can used last inch.
Fig. 9 A and Fig. 9 B are the Wound product 1b of the 3rd table apparatus.The flat board 2 of millboard is placed the line bend of going forward side by side along the reel 5 around the volume machine, and a gap 3 is arranged on both sides like this, forming volume core 2a, the end of thin plate or film 4 be secured to volume core 2a and film around volume core 2a around volume.
Shown in the detail drawing among Fig. 9 B, in the situation that adopts this device, insert thin plate or film in the gap 3 between dull and stereotyped 2 the side.Like this, can prevent the side circumferential displacement, in the process of thin plate or film 4 loose windings, can prevent that the internal diameter of rolling up core 2a from reducing like this.Equally, the end 4a of thin plate or film 4 is secured to volume core 2a, can carry out around volume in skid-resistant situation like this.After volume, can prevent from rolling up core 2a axial displacement.Like this, applying under the situation of suitable tension, thin plate or film 4 can used last centimetre.
Figure 10 is the Wound product 1c of the 4th table apparatus.The flat board 2 of millboard carries out cylindric bending along the reel around the volume machine, and the side of crooked flat board 2 will be connected together like this, and the end that forms volume core 2a and thin plate or film 4 is secured on the volume core, and film is carried out around volume.
In this device, even the both sides of the flat board 2 that joins connect without binding agent, can not slide in both sides yet.After volume, in thin plate or film loose winding process, volume core 2a will keep cylindric, and not shrink.Applying in the situation of some tension like this, this volume can use last centimetre.
The volume core example that Figure 11 uses for the Wound product that another table apparatus is rolled into.Shown in the on line among Figure 12, it is by cylindric crooked rectangular flat 2 and use adhesive agent 9 that two edges are bonded together formation.Figure 13 is another example of rectangle 2a.Shown in the chain line among Figure 14, it is by cylindric Bending Rectangular dull and stereotyped 2 and use adhesive tape 10 with the two ends formation that sticks together.
This flat board 2 can carry out cylindric bending by placing it on the volume reel of machine or spool.As what introduce above,, form volume core 2a by connecting two ends.By around volume thin plate or film 4, can produce Wound product.Flat board can carry out the tubular bending in advance, and its two ends link together, and is placed on the reel of volume machine.By using binding agent or adhesive tape to connect dull and stereotyped 2 two ends, the shape conservation degree of volume core 2a can be further improved.
Figure 15-17 is the Wound product 1d that the 5th table apparatus is produced.In Wound product 1d, as the Wound product 1a shown in Fig. 8 A and Fig. 8 B, the faying surface 2b by between dull and stereotyped 1 the both sides carries out the tubular bending with flat board 2, forms volume core 2.Long band thin plate or film 4 are stuck at its end 4a in the situation of inboard of the volume core 2a between the two edges of overlap joint, carry out around volume.
In Wound product 1d, shown in Figure 15 and 16, the two ends at volume core 2a are equipped with the block of making of synthetic resin.Each block 8 includes assembled portion 8a and an end is that flange portion 8b joins with the end face of rolling up core 2a.Because the two ends of volume core 2a are from stretching out around the two ends of volume thin plate or film 4, between the two ends of thin plate or film 4 and 8 the flange portion of blocking a shot, form gap s like this.
The restriction of 8 assembled portion 8a because volume core 2a is subjected to blocking a shot diametrically, the shape conservation degree of rolling up core 2a like this will improve.After volume, unclamp in the process of use at thin plate or film 4, can prevent from rolling up core 2a and shrink.Because film or web width increase, this will be more effective also.
According to thin plate or thin-film width, namely roll up the length of core 2a, have the block of the assembled portion 8a of different length by use, can more effectively solve the problem of wide thin plate or wide film 4.
Because block 8 assembled portion 8a is contained in the volume core at two ends of flange portion 8b, join with the end face of volume core 2a in addition, the latter also is restricted in the axial direction.Like this, after volume, in the process of unclamping thin plate or film 4, can prevent from reliably rolling up core 2a and move axially or break away from Wound product 1d.
Because at the flange portion 8b of block 8 with around rolling up gapped s between the thin plate film end face, after volume, when using in thin plate or the thin-film process by pulling method, two ends keep not contacting with flange portion 8b.If the assembling block can not break down.
When transporting Wound product, even when an end in contact terrace face of Wound product 1,, can prevent to damage Wound product 1 like this because the end face of volume core 2a or the end face of thin plate or film are incited somebody to action not direct contact terrace face.
If selected dull and stereotyped 2 length B, gapped 3 between two edges, and as shown in the figure, by the end that thin plate or film 4 are blocked in gap 3, form volume core 2a and around the volume core around the volume film, block 8 can be assemblied in its two ends.
Equally, as shown in Figure 1, if form volume core 2a, cylindric bent flat plate 2, gapped 3 between its two edges, then the end of thin plate or film 4 is secured to volume core 2a, and around volume core 2a around volume, block can be assembled to the two ends of volume core 2a.In this device, the end of thin plate or film 4 is stuck in the gap 3, to prevent dull and stereotyped 2 circumferential displacement, has so just realized anti-skid effect.
In addition, in device shown in Figure 10, dock mutually the two edges of the flat board 2 of cylindric bending, to form volume core 2.The end 4a of thin plate or film 4 is secured on the volume core 2a, and block 8 can be assembled to the two ends of volume core 2a.
In the device shown in Fig. 8 A and Fig. 8 B, except assembling block 8, the end 4a of thin plate or film is stuck in the gap 3 of two edges of flat board 2 of cylindric bending, has so just improved the shape conservation degree of rolling up core 2.Thin plate or film 4, block can be assembled to the two ends of volume core 2a.In device shown in Figure 10, two faying faces of dull and stereotyped 2 will can not slide over each other, and assemble block, improve the shape conservation degree of reel 2a.Behind volume, volume core 2a will can not shrink in the process of unclamping thin plate or film, apply in the situation of some tension, can make thin plate or film around volume use last inch.
Be another table apparatus at Figure 19 and Figure 20, except using two dull and stereotyped 2a, 2b forms the volume core and a plate is placed into around another piece plate of volume machine reel upper outside, and other device is basic identical, and wherein the Width of one flat plate is little around the width of rolling up film.
Table one contracts and around the influence test results of testing of volume displacement for the stretched film Wound product furls at the tension force opposing connection that puts on stretched film in licking journey.
In the volume test, by around the volume machine, with thickness is that 18 μ m width are that the polyolefin resin film of 500mm carries out around volume, regulate the speed between reel 5 and the spool 6 simultaneously, set different numerical value at the tension force that will put on each unit width on the stretched film, 8kg/m.5kg/m and during 0.5kg/m, by to have different-thickness and internal diameter be around rolling up various stretched film Wound products on 3 inches the paper tube around being rolled onto with it.After under 40 ℃ of atmosphere, placing 4 hours, check that whether paper tube is owing to destroying or the no phenomenon that is subjected to displacement around furling contracting.
The result as shown in Table 1.For applying the Wound product of 0.5kg/m tension force around volume, as shown in Figure 18, on whole axial width, form the dark opening of 10mm around the stretched film Wound product surface of volume and measured opening and widened width, its width is 2mm.This has just satisfied opening of the present invention and has widened the following condition of 5mm.Like this, if the thin paper tube thickness is below the 4.5mm, can not produce compression failure or around the volume displacement.
On the contrary, widen width at opening when rolling up tension force partly greatly to 5kg/m or 8kg/m and be respectively 8mm and 12mm.Because the residual stress of stretch-draw film has very high around the volume convergent force, if paper tube thickness is below the 5mm, paper tube can produce compressibility and destroy.
In addition, when in 40 ℃ atmosphere, placing 4 hours, can take place around the volume displacement around Wound product.
Like this, widen width by measure the otch that forms around volume stretch-draw film roll product surface at whole axial width, can determine the reading of the residual stress of stretched film, namely around the shrinkage degree of rolling up.According to the present invention, because stretched film is to apply in the situation of as far as possible light tension force around volume in stretched film, the residual stress in the stretched film and reduce around the volume convergent force.Like this, just do not need to use the high strength paper tube to be used as rolling up core.Even during as the volume core, can not take place in addition, if be placed under the high temperature, can not take place around rolling up displacement because making being compressed property of volume core destruction around furling contracting through the cylindric paper tube that is bent to form at the flat board that uses millboard yet.
As mentioned above, according to this invention, because the volume core is to form by the flat board that cylindric crooked millboard or resin board are made, after using, it can revert to flat board like this.Thereby it can not resemble big volume the common paper tube, is easy to scrap and reclaim.
In addition, dull and stereotyped two edges are by cylindric bending, provide the gap that receives the film end, docking two edges between its two edges or thin plate or film end stung into reel to prevent mutual slip.Like this, the volume core has required shape conservation degree.Pulling out, using, can prevent to roll up core contraction and volume mandrel to displacement through in the thin plate or thin-film process of volume.When applying certain tension force, long band thin plate or the film around volume can be used at last like this.
In addition, when the end of thin plate or film is advanced to roll up core by engagement between the dull and stereotyped two edges, just do not need the end is fastened to the outer garden of volume core perimeter surface, like this, has just simplified around volume work on the surface.
Moreover, because each block all has assembled portion and flange portion to be assemblied in volume core end, roll up core like this and be restricted diametrically, thereby the shape conservation degree is improved.Even the width of film or thin plate is bigger like this, in pulling out use thin plate or thin-film process, can prevent that rolling up in-core directly reduces.Moreover, owing to reduced diametrically be subjected to the blocking a shot restriction of flange portion of its two ends, can prevent from reliably rolling up core and move or skid off.So just can in the situation of the tension force that applies a little, thin plate or film be used at last.
In addition, widen width, can control the unrelieved stress of stretched film, promptly around the volume degree of shrinkage by measuring the opening that forms around the stretched film volume surface of volume.Like this, by applying as far as possible light tension force around the volume stretched film, make opening widen width and be default definite value, can not produce compressibility and destroy.Moreover, if long-time the placement at high temperature can not produce around the volume offset phenomena.
