Description

Welding wire container and manufacture method thereof

Technical field

The present invention relates to a kind of welding wire package, particularly a kind of square or polygonal packing is for conversion into welding wire package, this welding wire package is as wire spool and can be used in combination with the brake equipment design of wire spool.

Background technology

The welding wire that uses on high production operation such as the automated welding platform is placed on to have and surpasses in the big packing of 200 pounds of welding wires.Welding wire coiled welding-wire coil coiling structure in this packing forms the welding wire volume around central disc core or central space hole.Can use limiting mechanism to prevent that welding wire volume and central disc core from moving in transit.For transportation and the release of controlling welding wire, can use top retainer or brake equipment, help control welding wire as brake hoop and unclamp from the welding wire volume.5,819, No. 934 patents at cooper (Cooper) show a kind of such packing, disclose a kind of wire spool that uses brake hoop control welding wire to unclamp from the welding wire volume.Be used as identical background information at this with reference to the patent of introducing cooper.5,746, No. 380 patents of Chung show another such packing, this Patent publish a wire spool, yet Chung is disclosed to be that the welding wire flow control apparatus that welding wire discharges from reel is controlled in a kind of different being used for.Also be used as identical background information at this with reference to the patent of introducing Chung.

The welding industry in, but the huge automated welding platform of operation amount come from the packing of welding wire without interruption, to extract welding wire, to carry out welding operation continuously.The arrival of this a large amount of use electrode wires has produced holding and supply the needs of the heavy packages of a large amount of welding wires.Common packing is a kind of reel, and the ring-type welding wire amasss into welding wire heap or volume in reel, and it has end face and packs an interior cylindrical surface of coaxial centre hole facing to the exterior cylindrical surfaces and the formation of reel with the center.Centre hole is filled by a cardboard cylinder core usually, shown in 5,819, No. 934 patents of cooper, around extending with the mandrel direction of packing axis coaxle.In common practice, reel has a top set collar, is used in transportation the welding wire body being fixed on its position.Shown in 5,819, No. 934 patents of cooper, this set collar is arranged on the welding wire top, pushes downwards with own wt to make welding wire to pull out from the welding wire body between core and the set collar.In addition, can utilize hold-down mechanism to increase downward pressure.

Welding wire in the packing in the form of a ring or the coiling structure twines along the packing axis, and forms the welding wire volume with top and bottom.The welding wire volume also comprises inner radial and outer surface, and extend between top of rolling up and bottom on these two surfaces.When extracting welding wire from packing, welding wire is extracted out from welding wire volume or coiling structure top, and like this, welding wire volume top moves down and enters into packing.As a result, welding wire volume top descends in packing, and the outside and the inner surface of welding wire volume are also shorter and shorter.

For with the welding wire dispensing device cooperating of welding machine, welding wire must be provided and delivered with the state of non-winding, non-distortion and non-upset, can produce more uniform welding like this and need not manually to look after.As everyone knows, welding wire has a tendency of pursuing predetermined state of nature, and this can have a negative impact to welding process.Therefore, welding wire must fully be controlled in the mutual action between welding wire package and the welding wire dispensing device.For helpful in this respect, the welding wire builder has produced a kind of welding wire with aptitude, if one section welding wire is placed on the floor, the natural characteristic of welding wire will become straight line basically; Yet in order to tie up a large amount of welding wires, welding wire is coiled to be put in the packing, can cause a large amount of welding wire distortion and mat when extracting welding wire from packing.As a result, for winding, entanglement or the upset that reduces welding wire, control extremely important to from packing, discharging welding wire.In the use of the bigger welding wire package that is suitable for automatic or semiautomaticwelding, this situation of welding wire will be bad more.

The release portion of welding wire package assists the control welding wire to send from packing, and need not cause the extra distortion of welding wire, thereby sends with guaranteeing the needed continuously smooth of welding wire.In the time the welding wire that damages need being taken out and provide and deliver welding wire to the welding wire dispensing device once more, tangling of welding wire or fracture either way can cause serious shutdown (incident).In this case, when welding wire takes out from welding wire package, the restorability of welding wire or state of nature are controlled just very important so that welding wire can not tangle.Welding wire package comprises a welding wire volume, and this volume has many welding wire circle layers that superpose to the top from the packing bottom.These circles form an internal diameter and an external diameter together, and wherein width or the external diameter than welding wire package is little substantially for the internal diameter size.In this respect, circle forms said inner radial in front and outer surface together.The restorability of welding wire and state of nature produce one and continue outside power in the welding wire circle, make the diameter of circle bear the influence of the power that makes its expansion.The wall of welding wire package has stoped its outside expansion.Yet when welding wire extracted from packing, the wall of packing had lost the influence to welding wire, and welding wire trends towards its state of nature under the effect of power.This just causes from the welding wire part of packing withdrawal loose, and may recoil back packing and other welding wire circles are interfered mutually and caused entanglement.Except state of nature, welding wire can have distortion to a certain degree, can cause the circle in the volume to pop up like this.

Draw-out device or set collar are used to control the withdrawal of welding wire and upspringing of making progress when the control welding wire extracts.By draw-out device or steady ring being arranged on the top of welding wire volume, and force its effect of upspringing naturally of restriction welding wire downwards, just can reach this effect.Downward power is the action of gravity of set collar, or the member of an independent generation power, for example is connected the elastic webbing between set collar and the packing bottom.Further, the downward power of the downward power of the best and welding wire extraction process the best is different in the packing loading process.Therefore when elastic webbing or other belts were used to keep the position of draw-out device or set collar in loading process, the gravitation energy of set collar is enough to extract or is tying up the relative position that keeps draw-out device and welding wire to roll up in the process.

Except controlling the brake hoop or the set collar of dispensing welding wire from packing, welding wire package can comprise further that the welding wire that helps is avoided crossing the package centre axis and around the inner disk core.In this respect, the central disc core can be placed in the cylindrical interior zone that is made of welding wire volume inside face in the packing.The inner disk core is coaxial with the dish mandrel that meets central authorities' packing axis.Coil of wire chamber that is generally ring-type of the common formation of inner disk core and external packing, welding wire only can move up along the packing axis in the chamber, and can not side travel.Put it briefly, central disc wick feed welding wire is rolled up and is produced an internal constraint, and the upper end perforate that helps the guiding welding wire to move up and stretch out welding wire package makes a welding wire volume of welding wire roll up not mutual interference mutually with other welding wire.

Welding wire also can be by other mechanisms, the packing bar control as shown in the patent of Chung.When welding wire came out from wire spool, the packing bar helped to control the welding wire of sending outside together with standpipe.

Though wire spool can be as the actv. welding wire container,, columned profile can not be adapted to the container as transportation and/or storage better.This comprises transportation from the welding wire builder to the end user, in end-user device moving process, store welding wire and/or in end user's equipment, store welding wire the welding wire builder.Be appreciated that, when being close to mutually, place a plurality of wire spools, when for example being placed on tray or other transportation meanss, contiguous wire spool cooperatively interacts with a very little contact portion, and all here application forces each other all focus on this very little contact portion.Can cause the infringement of wire spool like this and to the potential damage of welding wire, these infringements be because contiguous wire spool or and other objects between less contact cause.We can also notice, can cause the distortion of welding wire to the infringement of welding wire, and welding wire is sent from packing and this process by welding wire dispensing device and/or welding wire welding torch has a negative impact.

Top margin

50,52,54 and 56 externally forms top end opening 100 on the box body 12, can be used for taking out welding wire from container 10.Be appreciated that when container 10 is in not running condition, comprise the top (not shown) of closed container 10.The top can be the top in any known technology in this area, comprises the plate that extends out from outside box body top margin from one or more.Further, closed bottom 98 and/or top can be the parts isolated with outside box body 12, so that isolated part is set to selectively cooperate with outside box body is inner, with the top and/or the bottom end opening of closed box.

First lining 14 is cylindric, and coaxial with vertical axis 32.Lining 14 defines the outside radius in ring-type welding wire chamber 30.As mentioned above, utilize first lining 14 to help to change the cubic box body structure of box body 12 into a reel shape welding wire container, and need not to lose the beneficial effect of cubic outline.First lining 14 comprises top margin 110 and relative base 112, and both define the height of first lining together, can same height be arranged with the outer box body wall.Be appreciated that of the desired height decision of the height of first lining 14 by welding wire chamber 30.First lining 14 further comprises first radially-outer surface 120 and first inner radial surface 122.The size of first lining 14 can be set, so that first inside face 122 has diameter 130, and first outside face 120 matches with the inside face of each box wall.Obviously, make its outside face match, can make welding wire chamber minimized in size with box body 12 by the size of setting first lining 14, yet, can between lining and box body, use spacer to change the welding wire chamber and/or further protect welding wire.

As discussed above, welding wire must be provided and delivered with the state of non-winding, non-distortion, non-upset.Therefore, the welding wire of producing has natural characteristic, and wherein, if a welding wire section places on the floor, the natural characteristic of welding wire should be a straight line substantially.The effect of this technology is when welding wire is set to web-like, can produce along the radially outer enormous power of spool.This power must be supported to keep the globality of welding wire volume.As a result, utilize outside box body 12 to help support that first lining 14 will be favourable.This structure can be appreciated that the cost that can reduce by first lining like this with helping to reduce the required intensity of first lining.Yet first lining can be designed as the oneself and supports, the function of wherein outside box body 12 mainly is the protection of loading and/or welding wire volume.

First lining 14 can be supported in many ways by outside box body 12.In this respect, and as discussed above, and the size that can set first lining 14 makes the outside face 120 of winning match with each box wall inside face.This cooperation can include but not limited to the direct contact between first outside face 120 and

inner wall surface

90,92,94 and 96.Also can comprise the intermediate structure parts between lining and the outside box body, to increase resting point and/or to increase protective capability.In this respect, container 10 can comprise the angle brace of speaking of above 20,22,24 and 26.In further detail, can set the size of angle brace and being configured to providing support near first lining 14 at outside box body turning.Equally, when welding wire was wound in the welding wire volume, the natural characteristic of welding wire produced outside diametral load, and the support of first lining here is very favorable.Help to support first lining in the big slit during angle brace is packed near the box body turning.

By helping outside diametral load to be forwarded on the outside box body to

angle brace

20,22,24 and 26 supports, first lining 14.As scheme to show that

angle brace

20,22,24 and 26 can comprise cylindrical outer surface 140,142,144 and 146 respectively.Set the size of angle brace, and dispose it and make these outside faces match with first external diameter surface 120 of box wall inside face along first lining.For example, angle brace 20 has columniform outside face 140, sets the size of outside face 140, and disposes it and match with first outside face 120, inside face 94 and inside face 96.Inside

face

94 and 96 cooperation can be on any surfaces at turning 74.Though cylindric angle brace is shown, other angle braces also can be used, and the outside diametral load of coiling welding wire is forwarded on the box body turning.The tubulose or the cylindrical structure that are appreciated that

angle brace

20,22,24 and 26 are constructed compared with other angle braces, are not easy distortion under the outside diametral load effect of coiling welding wire more.Yet, also can use other angle brace structures, and can not impair the present patent application.

Another angle brace that can be used to support bush 14 is for example energy absorbing foaies of solid angle brace (not shown).This can comprise prefabricated foam embolus, and this embolus is modelled as the space between filled liner and the outside box body, perhaps can be the liquid foam that is injected into opening part between turning and the lining, then sclerosis.But be appreciated that can use but be not limited to some hardened foam materials and fill these turning gap areas, a kind of packaging arrangement of more rigidity is provided, this structure has increased the radial support to welding wire volume, and even has increased the protection of welding wire volume.Yet, should be noted that the angle brace of solid type does not need the corner region of complete filling box body.The solid angle brace can include but not limited to a kind of solid circles cylindricality structure, as above-mentioned angle brace, and can comprise inside opening and obtains required absorption factor and/or reduce cost.

When the height of

angle brace

20,22,24 and 26 did not need with outer box body wall or lining same height is arranged, this angle brace can be configured to be used as and pile up upholder, piles up a plurality of packings each other.In this respect, be appreciated that the size according to container 10, container 10 can be more favourable for the container that easily stacks, and makes a container can be stacked on another container like this, and can not damage bottom container or bottom welding wire volume.Angle brace can be configured to support place the load on packing top, and will load to roll up from welding wire and be directed away.This can include but not limited to have and the outside box body angle brace of equal height substantially, makes anyly to begin to make the top load of outer box body deformability to act on mutually with angle brace.Being appreciated that the identical box body that piles up mutually can be stacked as makes the angle brace location that superposes each other.This situation allows angle brace can directly support the top load.Yet container 10 can further comprise top and/or lower support plate (not shown), and this mounted panel can be used on basic all angle braces of loading of guiding.For example, container 10 can comprise square top and/or the bottom plate identical with box body 12 cross-sectional configuration, is positioned near closed bottom and/or the top end opening.

Second lining 16 also is cylindric and also coaxial with vertical axis 32.Second lining 16 comprises in second external diameter surface 150 and second that to surface 152, they are 32 coaxial with axle.Second lining has top margin 154 and relative base (not shown), and they define the second lining height together.Top margin 154 can be circle, from the process that the welding wire volume unclamps, further helps prevent the infringement to welding wire at welding wire.The second export-oriented surface, 150 diameters 160 that have less than first lining, 14 diameters 130.

Lining

14 and 16 can be made by any known materials in this area and any known manufacturing methods.Fig. 2 institute best image for example, lining can be by strip or flaky material manufacturings, are rolled into cylindrical structure and are positioned in the middle of the outside box body.Further, lining can be seamless, includes but not limited to mold liner or or even compacting lining.In addition, consider the outside diametral load that the welding wire volume produces, the force rate that the welding wire volume applies lining 14 is bigger to the power that lining 16 applies.Therefore lining 14 can have the characteristic different with lining 16.This can comprise having different lining structures, different lagging materials and different bushing design.In fact, lining 14 can be built as more more solid than lining 16.

As mentioned above,

lining

14 and 16 defines ring-type welding wire chamber 30.In more detail, the welding wire chamber is limited by second outside face 150 of first inside diameter surface 122 of first lining 14 and second lining 16.Because the difference between the

diameter

130 and 160 of respective surfaces, these surfaces define the radius in ring-type welding wire chamber.Further, extend between the

top margin

110 and 154 of closed bottom 98 and lining in welding wire chamber 30.Be appreciated that the size that can set lining, make that their corresponding height is identical with the height of box wall, perhaps lining can have different height.Further, first and second linings needn't have identical height.Yet, be appreciated that ring-type welding wire chamber limited by the lining height.

Welding wire 170 is wound and is positioned in the middle of the ring-type welding wire chamber 30, thereby has formed welding wire volume 172.Welding wire is rolled up 172 and is had volume top 174 and volume bottom 176, defines together at least and rolls up height than lining 14 short welding wires.The welding wire volume highly also can be shorter than lining 16.As above more detailed argumentation, the natural characteristic of welding wire have produced huge outside diametral load, must be controlled by welding wire container.Therefore, to have complete radially outer support be favourable for welding wire volume.Though also can preferably have complete radially inner support, the function of lining 16 and/or purpose are different with lining 14, and this point will be discussed in more detail hereinafter.Welding wire volume 172 also comprises external diameter edge 180 and internal diameter edge 182, and wherein external diameter edge 180 is supported by first lining 14.

The welding wire 170 of web-like can twine with any known welding wire winding method in this area and be positioned in the welding wire chamber 30.As known in the art, the winding method of many welding wires comprises the method that second lining 16 puts in place that need not, and the internal diameter edge 182 formed inner welding wires that allow the welding wire wind to put in by the welding wire volume wind off in the hole.After welding wire was wound in welding wire volume 172, second lining was placed subsequently and puts in place.Consider the outside diametral load that the welding wire natural characteristic produces, the internal support of welding wire volume is not necessary in winding process.Yet, followingly will be discussed in more detail describedly, during welding wire discharged or unclamps, second lining can be used to help guiding output welding wire to be entangled with preventing to top box body opening part.

As mentioned above, welding wire distributes the welding wire stream that makes welding wire avoid being entangled with and supplying the welding wire operation and is not interrupted from container 10, and this point is extremely important.Therefore, the mode so that a kind of like this welding wire distortion is minimized forms welding wire volume 172 thereby welding wire is rolled into ring-type.In addition, have been found that it is favourable that welding wire is rolled into the circle that has identical effective diameter each other.In this respect, be rolled into a circle, be rolled into another circle identical simultaneously, can finally make a circle and next circle produce different distortions with diameter 130 with effective diameter identical with diameter 160.In addition, when the effective diameter of each circle was reduced, the possibility that changes the welding wire natural characteristic was also increasing.Be appreciated that and only be the example purpose wire loop will significantly be changed and/or eliminate fully the natural characteristic of welding wire around the pencil winding, welding wire should be kept straight natural characteristic as far as possible.In addition, wire loop is compared with the natural characteristic effect that has the reel generation of two ft diams around around the natural characteristic effect that the pencil winding produces, and remarkable difference is arranged.Therefore, wish to keep as wide as possible constant effective ring footpath of each shape.

As a result, welding wire 170 is curled to make each effective circle have diameter group 130 big 50 percent diameters be favourable.In addition, because effectively the wire loop diameter is big more welcome more, so gage of wire has been maximized.Therefore, diameter group 130 big 70 percent wire loop diameters, diameter group 130 big 80 percent wire loop diameters and diameter group 130 big 90 percent wire loop diameters can be used to make the change of welding wire natural characteristic to minimize.Be appreciated that the circle in each welding wire volume can be not coaxial with axis 32 when welding wire volume and axis 32 are coaxial.Yet, do not consider the position of circle in the welding wire volume, according to natural characteristic, it finally obtains the support of first lining 14 on the direction of expansion radially outward, and lining 14 can be supported by box body 12.

A kind of in container 10 method of packaging welding wire roll, can be included in welding wire and be wound and put into before the welding wire chamber, externally place first lining 14 in the box body 12 along

angle brace

20,22,24 and 26.Then, welding wire 170 is wrapped in the welding wire volume 172, subsequently second lining 16 is put into inner welding wire and wind off the hole.Another method of the present invention comprises step:

A kind of polyhedron container is provided, has the coaxial outer surface level sidewall of a plurality of and vertically extending vessel axis, each sidewall has top margin, base and inner wall surface, and the interval between top margin and the base defines the height of container; Corresponding a plurality of vertically extending turnings between each sidewall; Closed bottom; With the top end opening that is used for taking out the welding wire volume.

By utilize the setting of lining in container 10, welding wire container 10 has the advantage of all polyhedron welding wire containers and the advantage of all winding drum solder wire containers.As mentioned above, the polyhedron welding wire container is a kind of welding wire container of cubic cross-sectional configuration for example, mainly has advantage on the delelivered payload capability of packing.These advantages include but not limited to provide stable packaging arrangement for contiguous packing.In this respect, the outline of side allows the overlapping together placement of a plurality of packings, forms stable packaging group.Also be appreciated that several cylindrical structures, as wire spool, contiguous mutually the placement can be rotated each other relatively, do not use some overlapping apparatus for placing not produce overlapping placement effect, as the spacer in space between a kind of suitable reel.The cooperation of rotating manner must be suppressed between the reel, and this problem is also unnecessary in square package.

The advantage of another capacity packing of polygon or square welding wire container is the easy stacking of packaging arrangement.In this respect, as mentioned above, use angle brace in cubic packaging structure also can be used to support the weight of the container that piles up mutually, the power of piling up can be gone up call away to from the welding wire volume, also allow the material of cheap and lightweight to be used for outside box body.Cylindrically shaped packaging such as drum welding wire container use container outer wall to support the weight of stacked containers.As a result, the outer wall of hydrostatic column must be enough firm in to support welding wire container and very heavy welding wire volume fully.This makes and uses the reel of quite hard outer wall to support the weight of stacking package to necessitate.These reels can comprise expensive material, and dealing with also can be very expensive.Be appreciated that it is favourable handling packing in the mode that is suitable for environment economically in producing the welding wire package process.As the result of stack-up issue, wire spool further makes package waste become difficult and expensive often by more than one material manufacturing.In this respect, as known in the art, reel often comprises metal bottom and the becket top that has the coarse fibre outer wall, and it has limited easy processing together and has utilized.

By using cubic cross-sectional configuration, outside box body can be used the cardboard manufacturing, and can use the homogenous material manufacturing of recycling easily.Further, can make angle brace with different materials, and because these two kinds of parts are isolated easily, they can be handled easily still according to the structure needs of angle brace.Further, also can be according to the required material character of lining by independent material manufacture lining, and need not to damage the ability that recycling of packaging utilizes.Even further again, the use with the isolated angle brace of outside box body if desired, allows all packing to make with paper products.

Even container 10 has the packing configuration of polygon or cubic cross-sectional configuration, the lining configuration provides the benefit that is used for the winding drum solder wire container that welding wire unclamps when product is in running condition.In this respect, as mentioned above, welding wire has a kind of natural characteristic, and the one section welding wire that downcuts from the welding wire volume will inevitably become straight.Though this has produced outside diametral load, also in the welding wire volume, produced the spring effect that makes progress, this is in the transportation of welding wire container, and the process that welding wire unclamps from the welding wire volume when welding wire is used for welding operation, must be controlled.Therefore, known in this field, can prevent that in the welding wire container transportation welding wire volume from popping up with suppressing mechanism, and prevent before welding wire uses that therefore welding wire is entangled with.Further, in the process of using welding wire to weld, braking or pinch device also can be used to help the control welding wire to unclamp from the welding wire volume.

For many years, for being used for the wire spool device, many devices are used to control the transportation of welding wire volume and unclamping of welding wire.Yet, these devices be for wire spool designed, and if be used for cubic cross-sectional configuration container or other polygonal structure containers, manyly will no longer play a role or can not effectively play a role.Therefore, though the packing ratio reel container of outside polygonal structure produces the advantage on how many delelivered payload capabilitys, in operation, the reel container is more preponderated.

With reference to figure 4-9, in one embodiment, container 10 comprises the resistance parts 200 that are positioned at welding wire volume top 174.The little three-dimensional body of resistance parts 200 for having outline and weight.This object reaches each other with respect to the welding wire volume and can move freely relatively.As a result, object 200 can not use in traditional cubic welding wire container, because they can not be retained on the welding wire volume top 174.Be appreciated that reaching the resistance parts that can move freely relatively with respect to welding wire volume each other will fall into the corner recess of cubic container very soon, and will break away from there and the contacting of the welding wire of from the welding wire volume, exporting.

14 and 16 is rolled up the appropriate locations that the top keeps the resistance parts at welding wire, and keeps the suitable height or the thickness 210 of resistance parts on welding wire volume top.Be appreciated that height 210 is bottom-to-top-heights of parts,, will change during to next position from a position according to size, structure and the density of used resistance parts.

That resistance parts 200 can have is evenly solid, vesicular and/or hollow structure.Be appreciated that structure and selected material density with function unit.The size of parts also can change, the parts from granule shape material components to several inches long.Further, as hereinafter being discussed in more detail, parts can have multiple outline, and can not damage in the present patent application.

Suitable resistance component height is the effect of Several Factors, includes but not limited to the weight of resistance parts, the outline of resistance parts and the frictional behavior of member outer surface.In this respect, the resistance parts can be used for controlling going up of welding wire volume and play effect.The resistance parts also can provide resistance or pulling force in the welding wire that unclamps from the welding wire volume.

The resistance parts have an overall weight together and control upward bullet of welding wire volume relatively.Abundant resistance parts can be used for making its overall weight to be enough to overcome the elastic force that makes progress in the welding wire volume.Compare with high density resistance parts, lower density resistance parts need bigger thickness 210 to come the elastic force that makes progress in the welding wire volume is obtained same effect.For example, use spheroid 200A to need littler height to reach same effect than spheroid 200A by the plastics manufacturing by the iron and steel manufacturing.

Turn over to have a talk about and use the resistance parts to produce resistance or pulling force on the welding wire of output, size, shape, material and density also will produce the ability generation effect of pulling force to the resistance parts.About the structure of resistance parts, parts can be spherical 200A, cylindrical 200B, elongated cubic cross-sectional configuration 200C and/or discoid 200D.These structures produce similar but different release characteristics.For example, when welding wire during by spherical resistance parts 200A, along with welding wire trends towards shifted laterally from neighbouring through spheroid.On the contrary, when therefrom extracting out, disc-shaped part 200D is also lifted by welding wire.Result as the lifting action has been found that identical resistance parts combination weight can produce bigger resistance.Find that also nickel coin shape thing can be used as the resistance parts, it can provide a kind of method that welding wire unclamps, the very environmental protection of obvious this method also controlled effectively easily.In this respect, be consumed in case be appreciated that welding wire, nickel coin shape thing will can not be dropped.Similarly, elongated resistance parts 200B and 200C also produce the unexistent rise resistance configuration of spherical member.Though several resistance unit architectures are shown, other structure also can use in container 10.

According to required weight of parts and required resistance property, the resistance parts in fact can be by any material manufacture.These materials include but not limited to metal, glass, polymer, the Agricultural Materials of nature material as handling.Some examples comprise foamed materials with good frictional behavior, marble, ball, nickel coin shape thing and even are used in packing on other industries as the packing ball.Yet this inventory only is the various resistance examples of members that can be used, and is not exhaustive to the unit type that can be used.

With reference to Figure 10-11, another embodiment is illustrated.In this respect, the welding wire container that is to use ring-type brake hoop 250 10 of demonstration.Brake hoop 250 also is used to control welding wire and unclamps from the welding wire volume.Ring 250 has inside circumference 252, neighboring 254, the basal surface between interior neighboring 256 and top surface 258.Ring 250 is arranged on the welding wire volume top 174, and basal surface 256 is matched with the part on welding wire volume top.Ring 250 further comprises the surface 260 that extends to the K/UP of inner edge 262 from basal surface 256.Inner edge 262 has the diameter 270 greater than diameter 160, thereby is created in the extraction opening 272 between the second export-oriented surface 150 of the edge 262 and second lining 16.Curved surface 260 provides the minimizing deformation inclined-plane, the welding wire of output is rolled up from welding wire be directed to the welding operation flow process.Because second lining 16 provides one of obstacle for extracting opening 272, it also helps the welding wire of output is guided out container 10 from the welding wire volume.Further, as mentioned above, top margin 154 can minimize further to make the infringement to welding wire 170 for circle.Therefore, though second lining 16 can have minimized support characteristic, it obviously helps the upwards welding wire of guiding output, and helps to avoid a welding wire circle to conflict mutually with another, reduces the possibility that welding wire is entangled with thus.
