Description

[Technical Field]

[0001] The present invention relates to a cover for a welding wire storage container, and more specifically to a cover for a welding wire storage container that is easy to use and does not require a separate head cap member, by having a cutout portion that can be quickly and easily removed and used when using the welding wire wound around the container. [Background technology]

[0002] Welding wire is a metal wire used for welding, and these welding wires are used in automatic and semi-automatic welding.

[0003] Methods for storing such welding wire include a method of storing the welding wire by winding it on a reel-shaped spool, and a method of storing the welding wire by winding it in a coil shape in a large-capacity welding wire storage container.

[0004] In this case, since a larger amount of welding wire can be stored in a welding wire storage container than in a spool, welding wire stored in a welding wire storage container is used in shipyards and other companies that have installed automated welding equipment.

[0005] The welding wire container includes a cylindrical body, a cover, and a sealing part. The cylindrical body is hollow, and the welding wire can be stored in the cylindrical body in a coiled form.

[0006] The cover is attached to the upper part of the cylindrical body to prevent the welding wire housed in the cylindrical body from coming off, and when the cylindrical body and the cover are attached to each other, the sealing part encloses and seals the attached portion of the cylindrical body and the cover.

[0007] When using the welding wire, the conventional cover is removed and a separate head cap member is attached to the cylindrical body, and the welding wire wound around the cylindrical body is connected to an external wire drawer through a hole formed in the head cap member.

[0008] When the welding wire wound in the welding wire container is used up, the container including the cover is usually used a predetermined number of times and then discarded. At this time, there is an inconvenience that not only the container but also a separate head cap member and various accessories must be disposed of together. Furthermore, there is also the problem of additional costs associated with manufacturing a separate head cap member in addition to the container.

[0009] Furthermore, welding wire storage containers can be classified into a single type, in which when the welding wire wound in one container is completely used up, the welding wire wound in the next container is connected to a drawing device, and an endless type, in which two storage containers are used in tandem, and when the welding wire wound in one storage container is almost completely used up, the end of the wire is connected to the beginning of the wire wound in the other adjacent storage container, allowing for continuous use.

[0010] In this case, according to the conventional technology, a cover must be manufactured and supplied separately depending on the type of welding wire storage container required by the customer, which increases the manufacturing cost. [Prior art documents] [Patent documents]

[0011] [Patent Document 1] U.S. Patent Publication No. 2001-0013479 (August 16, 2001) Summary of the Invention [Problem to be solved by the invention]

[0012] The present invention is intended to solve the above-mentioned problems of the prior art, and an object of the present invention is to provide a cover for a welding wire storage container that is easy to use and does not require a separate head cap member, by having a cutout that can be quickly and easily removed and used when using welding wire wound in the container. [Means for solving the problem]

[0013] In order to achieve the above object, one aspect of the present invention provides a cover for a welding wire storage container, including: a blocking portion having a shape corresponding to the cross section of a tubular main body and covering an opening of the tubular main body; a side forming portion connected to the blocking portion and bent from the blocking portion to fit around the upper outer surface of the tubular main body while wrapping around the upper outer surface; side fixing portions provided alternately with the side forming portions along the edges of the blocking portion and fixing adjacent side forming portions; and a cut-out portion formed on the blocking portion and configured to be cut-out so that the welding wire wound around the tubular main body can be pulled out to the outside.

[0014] In one embodiment of the present invention, the cutout may include a first cutout formed in a circular shape at the center of the interrupter.

[0015] In one embodiment of the present invention, the cutout may include a second cutout having: a first linear portion and a second linear portion formed in parallel from one side of the cutout to a center portion; a curved portion formed to connect the first linear portion and the second linear portion at the center portion of the cutout; and a third linear portion formed to connect the first linear portion and the second linear portion while overlapping one side of the cutout.

[0016] In one embodiment of the present invention, the second cutout may be configured such that the first cutout formed at the center of the blocking part is positioned within an area surrounded by the second cutout.

[0017] In one embodiment of the present invention, the first cutout portion comprises a first arc portion and a second arc portion configured to have different ratios of the cutout portion per unit length.

[0018] The cover for a welding wire storage container may be characterized in that a ratio R1 of the cut-out portion per unit length of the first arc portion is greater than a ratio R2 of the cut-out portion per unit length of the second arc portion.

[0019] In one embodiment of the present invention, the cover for a welding wire storage container may be characterized in that a ratio R3 of the cut-out portion per unit length of at least one of the curved portion and the third straight portion is greater than a ratio R4 of the cut-out portion per unit length of the first straight portion and the second straight portion.

[0020] In one embodiment of the present invention, the cover for a welding wire storage container may further include a connection adapter that is detachably connected through a connection hole formed by removing the first cutout portion and that guides the withdrawal of the welding wire wound around the tubular body.

[0021] In one embodiment of the present invention, the connection adapter may be a cover for a welding wire storage container, comprising: a support portion; a first bolt portion formed on an upper side of the support portion and to which a cable member for drawing out welding wire is connected; a connect portion having a second bolt portion formed on a lower side of the support portion and having a through hole formed in a central axis direction; a first washer fitted on the second bolt portion and protecting an upper surface of the interrupter portion when coupled; a second washer fitted on the second bolt portion and protecting a lower surface of the interrupter portion when coupled; and a nut fitted to the second bolt portion and firmly fastening the connect portion, the first washer, and the second washer. [Effects of the Invention]

[0022] According to one aspect of the present invention, a cover for a welding wire container has a cutout portion and can be used immediately by itself without a separate head cap member, and can be embodied as an adapter connection type or an endless type depending on the application.

[0023] Furthermore, by configuring the ratio of the cut portion per unit length of the cut portion to vary from portion to portion, the cut portion can be removed more efficiently.

[0024] The cover for the welding wire storage container can be manufactured by assembling the side forming portion and the side fixing portion. Such a cover for the welding wire storage container can be manufactured without a separate binding member, and the manufacturing process is simple.

[0025] Furthermore, the assembled cover portion is made of cardboard, and when the assembled cover portion is disposed of, no additional industrial waste is generated.

[0026] The effects of the present invention are not limited to the effects described above, but should be understood to include all effects that can be inferred from the specific description of the present invention or the configuration of the invention described in the claims.

DETAILED DESCRIPTION OF THE INVENTION

[0028] The present invention will now be described with reference to the accompanying drawings. However, the present invention may be embodied in various different forms and is not limited to the embodiments described herein. In addition, in the drawings, parts that are not relevant to the description are omitted in order to clearly explain the present invention, and similar parts are designated by similar reference numerals throughout the specification.

[0029] Throughout this specification, when a part is said to be "connected" to another part, this includes not only "directly connected" but also "indirectly connected" through another member in between. Furthermore, when a part is said to "include" a certain component, this does not exclude other components, but means that the part further includes other components, unless otherwise specified.

[0030] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0031] FIG. 1 is an exploded view of a cover for a welding wire storage container according to one embodiment of the present invention, FIG. 2 is an assembly view of a main part showing a process of assembling the cover for a welding wire storage container according to one embodiment of the present invention, and FIG. 3 is a perspective view of the assembled cover for a welding wire storage container according to one embodiment of the present invention.

[0032] 1 to 3, the cover 1000 for a welding wire storage container of the present invention is assembled to form the cover 1000 for a welding wire storage container. The cover 1000 for a welding wire storage container is configured to be attached to and detached from the upper part of the tubular body P and to selectively close the opening formed in the upper part of the tubular body P.

[0033] Such a welding wire container cover 1000 can be made of cardboard, so that when the welding wire container is discarded, the assembled cover 1000 can be recycled as waste paper.

[0034] The cover 1000 for a welding wire storage container of the present invention includes a blocking portion 100 , a side forming portion 200 , and a side fixing portion 300 .

[0035] The blocking portion 100 has a shape corresponding to the cross section of the cylindrical main body P.

[0036] When the welding wire storage container cover 1000 is coupled to the cylindrical body P, the interrupter 100 covers the opening.

[0037] The side surface forming portion 200 is bent from the blocking portion 100 to form the side surface of the welding wire storage container cover 1000. When the side surface forming portion 200 is coupled to the cylindrical body P, it is fitted to the cylindrical body P while enclosing the upper outer surface of the cylindrical body P.

[0038] The side forming parts 200 are alternately connected to each side of the blocking part 100 together with the side fixing parts 300. That is, the side forming parts 200 and the side fixing parts 300 are alternately provided along the sides of the blocking part 100.

[0039] The side surface forming portion 200 includes a side surface extension member 210 and a wing member 220 .

[0040] The side extension member 210 has a width corresponding to the side of the blocking part 100 and extends from the blocking part 100. In this case, the length of the side extension member 210 extending from the blocking part 100 is equal to the height of the cover 1000 for the welding wire storage container.

[0041] The wing members 220 are a pair and are connected to both sides of the side extension member 210. The frame of the wing member 220 is configured to abut against the first fixed extension member 310, the connecting member 320, and the second fixed extension member 330 when the side forming part 200 and the side fixing part 300 are unfolded. The wing member 220 can be manufactured by cutting along the boundary line L while the first fixed extension member 310, the connecting member 320, and the second fixed extension member 330 are connected.

[0042] The side forming portion 200 having the side extension member 210 and the wing member 220 is bent from the blocking portion 100 to form the side of the welding wire storage container cover 1000 .

[0043] Meanwhile, the side fixing portions 300 are provided alternately with the side forming portions 200 along the sides of the blocking portion 100 to fix the adjacent side forming portions 200 in place.

[0044] These side fixing portions 300 include a first fixed extension member 310 , a connecting member 320 , and a second fixed extension member 330 .

[0045] The first fixed extension member 310 extends from the side of the blocking part 100. Here, the first fixed extension member 310 supports and fixes the outer surface of the wing member 220 bent from the side extension member 210.

[0046] The connecting member 320 is configured to connect the first fixed extension member 310 and the second fixed extension member 330. That is, one end of the connecting member 320 is connected to the first fixed extension member 310, and the other end of the connecting member 320 is connected to the second fixed extension member 330.

[0047] At this time, the connecting member 320 extends a predetermined length from the first fixed extension member 310. These connecting members 320 form a distance between the first fixed extension member 310 and the second fixed extension member 330 so that the first fixed extension member 310 and the second fixed extension member 330, which are bent from both ends, respectively, support and fix the wing member 220.

[0048] The second fixed extension member 330 is connected to the other end of the connecting member 320, and supports and fixes the inner surfaces of the wing members 220 bent from the side extension members 210. That is, the second fixed extension member 330 is bent from the other end of the connecting member 320, and supports and fixes the inner surfaces of the wing members 220.

[0049] Insertion members 340 are provided at the ends of these second fixed extension members 330, and the side fixing parts 300 are supported and fixed to the blocking part 100. Specifically, fitting holes 110 are formed at the centers of the sides of the blocking part 100 to which the side fixing parts 300 extending from the blocking part 100 are connected. The insertion members 340 are inserted and coupled into these fitting holes 110, and the side fixing parts 300 can be coupled to the blocking part 100 in a state where they support and fix the wing members 220.

[0050] At this time, the insert member 340 and the fitting hole 110 may be coupled in an interference fit manner.

[0051] 1, the specific shape of the side fixing part 300 will be described. The first fixed extension member 310 has a shape that gradually narrows as it extends from the blocking part 100. That is, the first fixed extension member 310 has a trapezoidal shape that narrows as it extends outward from the blocking part 100.

[0052] The second fixed extension member 330 has a shape that gradually widens as it extends from the other end of the connecting member 320. That is, the second fixed extension member 330 has an inverted trapezoid shape that gradually widens as it extends toward the outside of the blocking part 100.

[0053] In this way, the first fixed extension member 310 is formed so that its width narrows as it approaches the connecting member 320, so that the length of the wing member 220 inserted into the space between the first fixed extension member 310 and the second fixed extension member 330 can be increased.

[0054] In addition, the second fixed extension member 330 is formed to have a wider width as it extends from the connecting member 320, so that the supporting area with the wing member 220 is increased, and the side fixing part 300 firmly supports the side forming part 200.

[0055] Such a welding wire storage container cover 1000 has a simple assembly structure and is easy to manufacture.

[0056] Furthermore, the welding wire storage container cover 1000 does not require a separate bundling member for bundling, and the manufacturing cost of the welding wire storage container cover 1000 can be reduced.

[0057] Furthermore, since the welding wire storage container cover 1000 is made of cardboard, no additional industrial waste is generated when the welding wire storage container cover 1000 is disposed of.

[0058] 4(a) and 4(b) show a first cutout and a second cutout, respectively, provided on a cover for a welding wire storage container according to one embodiment of the present invention.

[0059] Referring to FIG. 4, the cover 1000 for a welding wire storage container of the present invention may further include a cutout portion 400 formed in the blocking portion 100 and configured to be cut out so that the welding wire wound around the tubular body P can be pulled out to the outside.

[0060] The cutout portion 400 is configured to be partially cut along a specific shape and can be easily removed by the user. That is, the user can immediately use the welding wire storage container cover 1000 itself without using a separate head cap member, and can pull out and use the welding wire through the removed portion along the cutout portion 400.

[0061] These cutouts 400 may include a first cutout 410 and a second cutout 420 that are each formed to be usable depending on the user's intended use.

[0062] At this time, the first cutout 410 is used when the welding wire container is used as an adapter connection type, and the second cutout 420 is used when the welding wire container is used as an endless type.

[0063] That is, two types of uses for the container can be realized through the container cover 1000 having the first cutout 410 and the second cutout 420 according to the present invention.

[0064] Referring to FIG. 4(a), the first cutout 410 may be formed in the center of the blocking portion 100, and may be preferably formed in a circular shape.

[0065] At this time, a coupling hole 120 may be formed in the portion removed along the first cutout 410, and a connection adapter 500 (described later) may be coupled through the coupling hole 120.

[0066] That is, the first cutout 410 is used when the welding wire container is used as an adapter connection type.

[0067] According to one embodiment, the first cutout portion 410 may be composed of a first arc portion 411 and a second arc portion 412 configured to have different ratios of the cutout portion c per unit length d. Preferably, the first arc portion 411 and the second arc portion 412 may each be configured to have a semicircular arc shape.

[0068] In this case, the ratio R1 of the cut-out portion per unit length of the first arc portion 411 can be configured to be greater than the ratio R2 of the cut-out portion per unit length of the second arc portion 412.

[0069] As a result, when a user removes the first cutout portion 410 using their fingers, the first arc portion 411, which has a larger ratio of the cutout portion per unit length, is removed first, followed by the second arc portion 412, which has a smaller ratio of the cutout portion per unit length, making it easier to remove the first cutout portion 410.

[0070] Referring to FIG. 4( b ), the second cutout 420 may be formed long from one side of the blocking part 100 to the center of the blocking part 100 .

[0071] More specifically, the second cutout portion 420 may include a first linear portion 421 and a second linear portion 422 formed parallel to each other from one side of the blocking portion 100 to the center portion, a curved portion 423 formed to connect the first linear portion 421 and the second linear portion 422 at the center portion of the blocking portion 100, and a third linear portion 424 formed to connect the first linear portion 421 and the second linear portion 422 while overlapping one side of the blocking portion 100.

[0072] At this time, an outlet space 130 may be formed in the portion removed along the second cutout 420, and the welding wire wound in the receiving container may be drawn out through the outlet space 130.

[0073] Therefore, as will be described later, when the welding wire storage container is used as an endless type, the drawer spaces 130 of two adjacent storage containers can be connected to each other, allowing the user to more easily implement an endless type storage container.

[0074] Meanwhile, the second cutout 420 may be configured to be located within an area surrounded by the first cutout 410 formed in the center of the blocking portion.

[0075] Therefore, when the welding wire storage container cover 1000 is used as an adapter connection type and is to be disposed of, the connected connection adapter 500 can be quickly removed through the second cutout portion 420 without separating it, thereby improving disposal efficiency.

[0076] According to one embodiment, at least one of the curved portion 423 and the third straight portion 424 may have a different ratio of the cut-out portion c per unit length d than the first and second straight portions 421 and 422 .

[0077] That is, the ratio R3 of the cut-out portion per unit length of at least one of the curved portion 423 and the third straight portion 424 can be configured to be greater than the ratio R4 of the cut-out portion per unit length of the first straight portion 421 and the second straight portion 422.

[0078] Therefore, when a user removes the second cutout portion 420 using his / her fingers, the user first removes the curved portion 423 or the third straight portion 424, which have a larger ratio of the cutout portion per unit length, and then removes the first straight portion 421 and the second straight portion 422, thereby making it easier to remove the second cutout portion 420.

[0079] FIG. 5 is a flow chart showing a process of connecting a connection adapter according to an embodiment of the present invention to a cover for a welding wire storage container, and FIGS. 6a and 6b are an exploded view and an assembled view of the connection adapter according to an embodiment of the present invention, respectively.

[0080] Referring to Figures 5 and 6, the case where the welding wire storage container cover 1000 is used as an adapter connection type will be described. The welding wire storage container cover 1000 of the present invention may further include a connection adapter 500 that is detachably connected through a connection hole 120 formed by removing the first cutout portion 410.

[0081] The connection adapter 500 is configured to be easily and quickly connected through the connection hole 120 and may be made of a hard material such as metal.

[0082] The welding wire wound around the container is guided to the outside by the connection adapter 500 and can be continuously drawn out through the cable member 40 connected to the connection adapter 500 and used as a welding material.

[0083] These coupling adapters 500 may include a connecting portion 510 , a first washer 520 , a second washer 530 , and a nut 540 .

[0084] The connecting part 510 is a part that forms the body of the connection adapter 500, and may include a support part 511, a first bolt part 512 formed on the upper side of the supporting part 511, a second bolt part 513 formed on the lower side of the supporting part 511, and a through hole formed through the connecting part 510 in the direction of the central axis.

[0085] At this time, the welding wire wound around the receiving container can be drawn out to the outside through the through-hole.

[0086] The support portion 511 is a portion that is supported by contact with the upper portion of the breaker portion 100 when the connection adapter 500 is coupled, and is formed integrally with the first bolt portion 512 and the second bolt portion 513 .

[0087] In addition, the support portion 511 serves to support the first and second bolt portions 512 and 513 between the first and second bolt portions 512 and 513, respectively, and the diameter of the support portion 511 may be larger than the diameter of the first and second bolt portions 512 and 513.

[0088] The second bolt part 513 is inserted through a coupling hole 120 formed in the interrupter part 100, and when the lower part of the support part 511 abuts and is supported by the upper part of the interrupter part 100, it is not inserted any further.

[0089] In this case, a first washer 520 may be provided between the upper part of the blocking part 100 and the lower part of the support part 511. The first washer 520 is a ring-shaped part having an internal hole formed therein, and serves to protect the upper surface of the blocking part 100 by dispersing pressure during coupling.

[0090] That is, the first washer 520 is fitted onto the second bolt part 513 of the connecting part 510, and the second bolt part 513 is inserted into the coupling hole 120 of the blocking part 100 with the first washer 520 fitted therein.

[0091] When the second bolt portion 513 is inserted into the coupling hole 120 , the nut 540 is connected to the second bolt portion 513 below the blocking portion 100 .

[0092] In this case, a second washer 530 may be provided between the lower part of the blocking part 100 and the upper part of the nut 540. The second washer 530 is a ring-shaped part having an internal hole formed therein, and serves to protect the lower surface of the blocking part 100 by dispersing pressure during coupling.

[0093] When the connection adapter 500 is coupled to the welding wire container cover 1000, the cable member 40 for drawing out the welding wire can be connected to the first bolt portion 512.

[0094] In this way, the connection adapter 500 can be firmly and easily coupled to the welding wire container cover 1000, and can be easily removed from the cover 1000 when all the welding wire stored in the container is consumed.

[0095] FIG. 7 is a perspective view showing how the second cutout of the welding wire container cover according to one embodiment of the present invention is used.

[0096] 7, when the welding wire storage container cover 1000 is used as an endless type, first, two storage containers are placed adjacent to each other, with the second cutouts 420 of each cover 1000 facing each other.

[0097] Next, the second cutout portion 420 provided on each cover 1000 is removed so that the drawer space portion 130 is formed in the cover 1000. At this time, the second cutout portion 420 can be more easily removed by using the curved portion 423 or the third straight portion 424, which are formed so that the ratio of the cutout portion per unit length is large.

[0098] Then, the welding wire 10 wound in one container is connected to the unwinding device 30 and used, and when the wound welding wire 10 is almost consumed, the end 11 of the welding wire 10 on one side is connected to the initial end 21 of the welding wire 20 wound in the other container. At this time, since the containers are placed adjacent to each other so that the second cutouts 420 face each other, connecting the welding wires can be performed more easily.

[0099] This allows for endless welding wire to be used without having to reconnect the drawer 30 to new welding wire.

[0100] Next, when the welding wire 10 wound in one container is completely consumed, a new container is placed adjacent to the first container, and the above process is repeated.

[0101] In this way, the user can more easily realize an endless type storage container by using the welding wire storage container cover 1000 having the second cutout portion 420.

[0102] The cover 1000 for a welding wire storage container of the present invention has a cutout portion 400 so that it can be used immediately by itself without a separate head cap member, and can be embodied as an adapter connection type or an endless type depending on the application, which has the advantage of improving manufacturing efficiency.

[0103] The above description of the present invention is for illustrative purposes only, and those skilled in the art will understand that the present invention can be easily modified into other specific forms without changing the technical spirit or essential features of the present invention. Therefore, the above-described embodiments should be understood to be illustrative in all respects and not limiting. For example, each component described as a single component may be implemented in a distributed form, and similarly, components described as distributed may be implemented in a combined form.

[0104] The scope of the present invention is defined by the claims that follow, and all modifications and variations that fall within the meaning and scope of the claims and their equivalents should be construed as being included within the scope of the present invention. [Explanation of symbols]
