Description

The bight method for folding of packing welding wire carton

Technical field

The bight that the present invention relates to a kind of packaging box of the welding wire by will packing medicine core (flux cored) welding wire etc. is pressed into the formation recess, and the bight method for folding of the packaging box of carrying easily.

Background technology

At shield carbon-dioxide arc welding, in MIG welding etc. full-automatic or the working welding wire of arc welding that semi-automatic welding is used, the flux-cored wire of filling flux in the outer belt steel of tubulose (fluxcored wire is also referred to as FCW) is widely used.In this FCW, include the type of seam (being also referred to as seam) and the seamless type of this seam not.Because therefore the manufacturing cost height of the latter's seamless type has the type of the FCW of seam to be widely used.FCW with this seam is that method such as need not weld engages this seam and makes the welding wire of its closed state.

So flux-cored wire is widely used with the wire drawing welding wire in the thin footpath of φ 0.8～1.6mm, usually, uses with cylindric coiling, manufacturing, transportation around coil core (bobbin).This coiled type welding wire from manufactory in goods stores keeping, shipment, transportation, up to delivery give the user during in, welding wire is incorporated in the rectangular-shaped carton.That is, the welding wire of coiled type is to be handled upside down with the state that is incorporated in this rectangular-shaped carton.

But this welding wire for example 1 volume is 20 kilograms, and is quite heavy.This weight thing for example is incorporated in the high carton of the square 11cm of 28cm.

When carrying this welding wire, the carton that the workman at first will tie up welding wire tilts, and earlier one hand is inserted below the one edge part and between the substrate, then the another hand is inserted below another edge part and between the substrate, after two hands all insert, lift carton and move to assigned position.But, being difficult to lift so weight with unsettled posture, its carrying also is heavy work in addition.For this reason, when the workman lifts goods, pain in the back takes place easily, perhaps when carrying goods easily from landing on hand, drop on the pin and have an accident.Particularly because the workman wears gloves usually, the therefore easy landing of carton that constitutes with paper, when some was neglected, goods had and drop on the pin and the danger that pin is come to harm.

In addition, a kind of central portion that will a broken line parallel with a crest line of case be located at this crest line has been proposed, be provided with the interconnective cut-out line in the end of each broken line, be provided with the packing case (Japanese kokai publication hei 5-262346 number) of recess thus at the central portion of described crest line.Hand can be put in this recess and carry this packing case.But, because this recess is to form by a part of cutting off case, so have the problem of intensity difference.In addition, with the state perforate on case that is provided with recess, therefore, packing becomes imperfect.

Therefore, so far, in Japanese kokai publication hei 3-14449 grade, proposed to solve the packaging board case of shortcoming of the packaging box of this welding wire.The packaging box of institute's motion is actually in the packaging board case that constitutes by 6, has at least two recesses of being located at the bight of 3 ribs gatherings, and each recess is by being bent to form interconnective 3 broken lines of described crest line to the inside.

With reference to accompanying drawing this packaging board case is specifically described.Fig. 4 is a stereogram of seeing the assembled state of the packaging box that has recess in described bight from the top, and Fig. 5 is the stereogram of seeing from its below, and Fig. 6 is a front view, and Fig. 7 is a bottom view, and Fig. 8 is an expanded view.For example this case 1 is cardboard system and is rectangular-shaped.And 4 bights below it are crooked to the inside, form recess 2.

Shown in the expanded view of the former material cardboard of Fig. 8, the former material cardboard that launches behind this packaging box has: facial 4 on cardboard bottom surface sections 3, the cardboard, cardboard face portion 10, cardboard back side portion 11,

paperboard side face

5,6, also possess as 7,8,9,12,13,14,15 of adhesive portion.And, on former material cardboard, also be provided with the broken line 16 that is used for these partially folded one-tenth approximate right angle.

Cardboard along these broken lines 16 folding Fig. 8 thus, forms rectangular-shaped packaging board case 1, holding welding wire, and the fixedly cardboard part 7～9,12～15 that bonds, and thus, the welding wire package of packaging board case 1 is finished.

In the expanded view of the former material cardboard of Fig. 8, also be provided with broken line 17 in 4 bights of cardboard bottom surface 3.This broken line 17 becomes the crest line of recess 2 in the bight of described packaging board case 1.

In the packaging board case 1 that so constitutes, at first,, bend to generally rectangular shape along broken line 16 and become rectangular-shaped, and undertaken in the process of bending machining by broken line 16 with the contour shape after the expansion shown in Figure 8, carry out bending machining along broken line 17.Like this, to shown in Figure 8, be assembled into packaging board case 1 as Fig. 5 with recess 2.

Zu Zhuan bale packing has the packaging board case 1 of welding wire like this, owing in its 4 bights recess 2 is arranged, therefore is positioned under the state on the bottom surface in workshop or warehouse, between the part of this recess 2 and the bottom surface slit is arranged.Therefore, the workman inserts this recess 2 with hand, under the state in finger tip inserts recess 2, lifts case 1.

Be provided with recess 2 in the bight of case 1 like this, therefore needn't make case 1 inclination and hand is stretched into the work in slit,, therefore lift case 1 easily owing to can directly hand be inserted recess 2.In addition, hand can be stuck in tote box 1 in this recess 2, so hand can not skid and makes case 1 landing with case.Therefore, the security during transportation can significantly improve, and handling efficiency is improved.In addition,, but the bight is provided with to the inboard depression of case owing to this recess 2 is not to cut off the bight to form, so, the intensity height of the part of this recess 2.

The packaging board case 1 that so possesses recess 2 in the bight is showing extremely excellent effect aspect the easiness of transportation.But, the packaging box plate is assembled into the rectangular-shaped of 6 bodies, be not to be in this assembling way, by manual operations that broken line 17 is folding, form recess 2 thus, but be assembled into rectangular-shaped after, mechanically promptly this bight is pressed into the case inboard by automatic operation, this operation is because this bight forms triangle taper ground projection, so very difficult.

Promptly as shown in Figure 8, for example in the triangle OAB that surrounds by broken line 17b and two crest lines, the length of line segment OA and line segment OB and obviously big than the length of line segment AB.In other three triangles too.Therefore, for the part that these

broken lines

17a, 17b, 17c, 17d is reached the triangular pyramid that is made of crest line OA, OB, OC is pressed into the case inboard, need very big strength.Therefore, bar-shaped pressing member is contacted with this bight be pressed into simply, the reaction force of the part in my bight is big, and the top corner portion of pyrometric cone is destroyed, and problems such as perforate perhaps can occur.

Therefore a kind of bight method for folding of packaging box has been proposed in the special fair 7-115431 of Japan number, improve described pressing member, can easily form recess in the bight of packaging board case 1, can be with automatic operation and make the packaging box possess this recess in large quantities.In the method, be actually the bight more than 1 or 2 in 8 bights that 3 ribs of the packaging board case 1 that constitutes by 6 are assembled, be pre-formed the broken line that interconnects described each 3 crest line, the bight that will be provided with described broken line by the pressing member that moves with circular-arc track is pressed into the inboard recess that forms of case.

In the special fair 7-115431 of Japan number embodiment, Fig. 9 represents the side view of this pressing member (press device), and Figure 10 represents the ideograph of its action.This press device for example disposes 4 groups corresponding to 4 bights of packaging box.In each press device, platform 120 is fixed, and is fixed with the supporting member 121 of supporting cylinder 123 above 120 at this.On this supporting member 121, level axial with it is provided with axis of rocking 122, and cylinder 123 can be that the center joltily is supported at its leading section with the trunnion axis by axis of rocking 22.The piston 124 of this cylinder 123 is driven by the device of hydraulic pressure etc., can forwards advance or return in the cylinder.

But Japanese as described special fair 7-115431 number is like that, uses the rock type pressing member (press device) of axis of rocking 122, complex structure, and device also maximizes easily.So, be used for implementing needed space, just need bigger space as packaging box bight method for folding (operation).

Press device:

Press device 20～23rd is provided with the fluid cylinder that is pressed into leading section 25 with the corresponding shape of outer rim shape of the recess 2 in 4 bights of packaging board case 1.Promptly has the piston (bar) 30 that the metal system band spirit cylinder 31 that is filled with work oil and slide (advance and retreat) connect freely in this cylinder 31.This piston 30 is driven by the mechanism of hydraulic pressure or air pressure etc., can forwards advance towards 4 bights of packaging board case 1, in addition, can return in the cylinder 31.

This fluid cylinder self can use the fluid with the gas of the liquid of wet goods and air etc. can convert the straight-line of bar 30 to, known hydraulic cylinder that is widely used or air air cylinder.Therefore, though press device 20～23 is not shown,, have the oleo-gear etc. that the pressing force make the direction that cylinder 31 and piston 30 shrink is alleviated in the containment member of upper opening of sealing cylinder 31 and the inside of being located at cylinder 31.

What Fig. 2 represented the press device 20～23 that amplifies is pressed into leading section 25.The shape that is pressed into leading section 25 forms the corresponding shape of outer rim shape with the recess 2 in 4 bights of

packaging board case

1, and 3 flanges (blade) 26 have the fletching shape with the equal angles configuration radially laterally around axle 27 at interval of 120 degree.In addition, the bearing portion 28 of the rear end of axle 27, chimeric piston 30 in the hole 29 of the heart located therein is pressed into leading section 25 and advances and retreat point-blank with the advance and retreat of piston 30.In addition, the situation from Fig. 3 to Fig. 7 is that the outer rim of recess 2 is shaped as the pyrometric cone shape.And, the so-called outer rim shape corresponding shape meaning with recess 2 be with this pyrometric cone shape in the shape that connects.

At this, the shape of the crest line of the shape of the crest line of the leading section 26a of described 3 flanges (blade) 26 and the broken line 17 of the packaging board of described Fig. 8 and the recess 2 in packaging board case 1 bight is corresponding, forms the conical in shape that tilts towards the rear (right side of figure) of piston 30.

Folding operation:

On the basis of above formation, in the folding operation in the bight 2 of packing welding wire carton 1, shown in Fig. 1 (b),, the leading section 25 that is pressed into of press device 20～23 is forwards released point-blank towards 4 bights of packaging board case 1.And the crest line of the leading section 26a that pushes blade 26 by press device 20～23 is pressed into (pushing) with the broken line 17 of described carton point-blank from oblique below.Thus, carry out the bending machining of broken line 17, make the recess 2 (the crest line shape of recess 2) in packaging board case bight.

Shown in Figure 8 as described, the broken line 17 of described carton is preformed by interconnecting 3 crest line AO, the BO, 3 broken line AB, the BC of CO, the CA that are gathered in bight O.Therefore the shape that is pressed into leading section 25 of press device 20～23 shown in Figure 2 is by pushing these 3 broken line AB, BC, CA respectively, with the taper crest line formation of each bar broken line AB, corresponding 3 flanges of BC, CA (blade) 26 and its leading section 26a.Therefore, make towards 4 bights of packaging board case 1 when being pressed into leading section 25 and forwards advancing, the crest line of leading section 26a by respectively pushing blade 26 can be pushed these 3 broken line AB, BC, CA respectively, can carry out the recess 2 that bending machining is made packaging board case bight smoothly.

As mentioned above, in order to be pressed into to the case inboard by the part of the pyrometric cone that 17a, 17b, 17c, 17d and crest line OA, OB, OC constitute, need very big power as recess 2, shown in Figure 8, the broken line in packaging board case bight.Similarly, as described above, only be pressed into by manually simply bar-shaped pressing member being contacted with this bight, the reaction force that is subjected to from the part in bight is big, and the top corner part branch damage of pyrometric cone has the problem generation of perforate etc.

But, so form the corresponding shape of outer rim shape with the recess 2 in 4 bights of packaging board case 1 by the shape that will be pressed into leading section 25, only this bight is pressed into point-blank by fluid cylinder, just can be easily form recess in the bight of packaging board case 1, can be with automatic operation and make the packaging box that possesses this recess in large quantities.That is,, also can easily form recess 2 even be not pressing member with the action of circular-arc track as the special fair 7-115431 of Japan number.

In addition, this shape that is pressed into leading section 25 also not necessarily must be the shape of described 3 pinna rachis 26, if can corresponding described 3 broken line AB, BC, the shape of CA (broken line 17 of carton or the crest line shape of recess 2), also can select other suitable shapes.It for example also can be the concaveconvex shape that has with the protuberance of the corresponding taper of crest line of the leading section 26a of described 3 blades 26, coniform or square taper.

Thus, method for folding of the present invention is by as being provided with the press device 20～23 of the fluid cylinder that is pressed into leading section, can be easily and make the recess 2 (the crest line shape of recess 2) in 4 bights of packaging board case 1 smoothly.Therefore, because the mechanism of press device is simple, so miniaturization that can implement device.For this reason, can reduce to be used to implement the space of the required setting of bight method for folding (operation) of packaging board case.

In addition, the present invention is not limited to above-mentioned embodiment, can carry out various variations.For example, the formation of recess is not limited to 4 bights in the bottom surface, also can form recess at least one bight.In addition, the foregoing description is in the position with the 4 bights coupling of the bottom surface of case 4 press devices to be set, even but when forming recess in a plurality of bights of 2 or 4 etc., press device shown in Figure 1 does not need to be set to the quantity corresponding to the bight that should form this recess yet, if by making the countermeasure of packing case rotation etc., press device has 1 to get final product so.In addition, when the bight on packing case forms recess, press device is moved.

According to the present invention, can form recess easily and promptly in the bight of packing welding wire carton, packing case that can in a large number production and transport excellence.In addition, the press device of use mechanism simple mechanism miniaturization can be realized the formation of these recesses.Thus, can be applicable to the continuous manufacturing process that requires the flux-cored wire that high efficiency and quality ensure etc.
