Description
Technical field
The present invention relates to carry out each other the ultrasonic welding structure of the plastic products that ultrasonic fusing obtains by plastic components to identical material.Thereby especially relate to the extended ultrasonic welding structure of size of spreading container piece, it has kept bond strength, and size has extended on desirable height, length and width.Structure
Background technology
All the time, people are just plastic container, are extensive use of as the common small sized container at factory's dress part etc., and this is that durability is good because it not only gently but also have mechanical strength, can clean simply for dirt is dirty, thereby usability is good.
In factory, the quantity in stock of the container of various sizes must be controlled at necessary bottom line, manage expeditiously.Therefore,, run into when needing all the time,, just implement the method for spreading in order to obtain size is lengthened to the container of desirable height, length or width.One is,, metal is close on the composition surface when extending its size at the spreading container, and with the method that rivet or pin engage, this method is widely used.But immediate cause environmental issue requires not discharge trade waste when handling discarded object.The lengthening goods of existing container use metals such as rivet and pin at seam crossing.Therefore, when discarding these article, must after the rivet and pin of the material that has separated unlike material, just can reclaim.In fact, so because to take time and energy be to abandon as trade waste at present.
Use riveted joint, the three-dimensional icon of the container 7 of the size that extended in the horizontal is in Fig. 1.Involutory the cut-out portion that vessel prepd is cut into container piece 7a, 7b after the necessary length, 7c, form junction surface J therefrom with gap.In the mode that strides across this junction surface J joint 8 is sticked, container piece 7a, 7b, 7c are joined together with rivet 82.In addition, by striding across junction surface J, cover bonding frame 81 from the top and the top portion of the sidewall 73 of container piece is strengthened.Here, joint 8 and bonding frame 81 are metal, for example are aluminums.Rivet 82 itself also is a metal.Therefore, the container or the corrugation paperboard of size have been increased, when using up the back and reclaim by spreading, be to decompose joint 8, bonding frame 81 and rivet 82 and will take time and energy, and, the situation that metal is sneaked in the plastic material as foreign matter is that inevitably separating then needs a lot of man-hours.
On the other hand, also can pass through ultrasonic vibration, the frictional heat of utilizing the junction surface to produce is to carrying out ultrasonic fusing between the container piece of same plastic material.At this moment, developed the ultrasonic wave bonding tool that the used leading section of ultrasonic fusing is a flat condition.Adopt this method, can reduce the generation of weld portion burr.For example, make ink tank and just adopted this method, this ink tank is received and is adorned the record head ink supplied that is used for to the ink-jet head chuck.That is, can prevent from reliably to overflow at the jar resin that case and Gai Shi produced that welding constitutes ink tank is the generation (with reference to patent documentation 1) of welding burr.
Here, ultrasonic fusing is explained.As shown in Figure 2, ultrasonic wave welding device 1 also has not shown hyperacoustic dispensing device, the pressue device of cylinder etc. except main shaft 100.The leading section of main shaft 100 has the wave welding head of ultrasonic wave 2 of ultrasonic wave bonding tool.From the top of junction surface J pushing wave welding head of ultrasonic wave 2, this junction surface J-shaped is formed in overlapping being placed on workpiece sheet 6a on the operation post 200, the equitant position of 6b.Then, on one side ultrasonic vibration is implemented on junction surface J pressurization, one side, thus, junction surface J just is heated, welding.Fig. 3 represents the shape of the wave welding head of ultrasonic wave and the leading section thereof of different shape.As shown in the figure, circular wave welding head of ultrasonic wave 21, square wave welding head of ultrasonic wave 22 and rectangle wave welding head of ultrasonic wave 23 soldering tip leading section P separately is a flat condition.Use such leading section to be the structure of the wave welding head of ultrasonic wave welding of flat condition, exist the low problem of heat seal strength at junction surface.That is, wave welding head of ultrasonic wave is pushed against on the position at junction surface of plastic components, by implementing ultrasonic vibration, produce frictional heat between the composition surface, this frictional heat makes that the workpiece sheet is softening, welding.But, be under the situation of flat condition at the leading section of wave welding head of ultrasonic wave, wave welding head of ultrasonic wave leading section P is more shallow to the nip degree of depth of (heading into) of the workpiece that has softened.
[patent documentation 1] spy opens the 2002-120383 communique
As previously discussed, the above-mentioned existing plastic structure that has extended is concluded, then existed following problem.When waste treatment, can not avoid metal to sneak in the plastic material as foreign matter.Again, use the structure of leading section as the wave welding head of ultrasonic wave welding of flat condition, the heat seal strength at junction surface is low.That is, the leading section of wave welding head of ultrasonic wave does not have when concavo-convex, because the degree of depth that the leading section of wave welding head of ultrasonic wave is nipped to the workpiece that has softened is often more shallow, so the heat seal strength at junction surface is low.
Summary of the invention
Therefore, the present invention In view of the foregoing provides a kind of ultrasonic welding structure, this structure, reclaim spreading container the time owing to elect the material of joint as same material, needn't decompose, separate, therefore, metal parts can not sneaked in the plastics as foreign matter, and, the intensity at plastic components junction surface to each other improves, and size is lengthened to desirable length, width, highly.Again, the invention provides a kind of like this ultrasonic welding structure of plastics,, adopt that not need out the joint method of operations such as rivet hole be ultrasonic fusing at the assembling box period of the day from 11 p.m. to 1 a.m, can be to desirable length, width, short transverse spreading.
A kind of ultrasonic welding structure is proposed, be formed with and make plastic components each other along putting down overlapping junction surface (J) up and down, carry out ultrasonic fusing on this junction surface (J) and form by wave welding head of ultrasonic wave (2) is pushed against, it is characterized in that, a side's who is made of plastic components container piece (7a) has bottom surface (71), base (72), sidewall (73), top (74), digging through above-mentioned bottom surface (71) afterwards, formation has reveals the exact details (75) and the container piece (7a ') of above-mentioned base (72), the opposing party's who is made of plastic components container piece (7b) has bottom surface (71), base (72), sidewall (73), top (74), overlap by above-mentioned base (72) on the above-mentioned top (74) of said vesse sheet (7b) said vesse sheet (7a '), formation makes above-mentioned base (72) and involutory above-mentioned junction surface (J), above-mentioned top (74), as required, and then on said vesse sheet (7a '), stack gradually the other container piece of similarly bottom surface being dug through (7a ') and form junction surface (J) respectively, be formed with a plurality of concavo-convex traces (9) on these junction surfaces (J), these concavo-convex traces (9) are dual circles.
Ultrasonic welding structure of the present invention owing to be identical plastic material joint to each other, so use up when reclaiming afterwards, can not sneaked into different materials.Even the dimensions of the container that uses increases, also there is no need the container of various sizes is held as the stock again.That is, obtain easily specification with the goods of packing into consistent, desirable length, highly, the container of width, the quantity in stock of container can be controlled at necessary bottom line, manage expeditiously.In addition, physical property such as the outward appearance of bonding part and tensile strength, percentage elongation, folding strength and disengaged do not have much difference.And, owing to needn't discard the bonding part,, obtained very good effect on the production technology so the finished material rate increases substantially.

With reference to Fig. 9～Figure 15, embodiments of the invention 2 are explained.
The main difference point of present embodiment and embodiment 1 is, after the junction surface that plastic components is involutory has added joint, carries out ultrasonic fusing again.
Fig. 9 is the key diagram of main points of the ultrasonic fusing of expression present embodiment.Figure 10 represents that front end is the wave welding head of ultrasonic wave of round convex shape, and Figure 10 (a) is a vertical view, and Figure 10 (b) is a side view.Figure 11 represents the round convex shape wave welding head of ultrasonic wave of another form, and Figure 11 (a) is a vertical view, and Figure 11 (b) is a side view.Figure 12 represents the wave welding head of ultrasonic wave of the front end side of being convex, and Figure 12 (a) is a vertical view, and Figure 12 (b) is a side view.Figure 13 represents that front end is the wave welding head of ultrasonic wave of two sleeve shapes, and Figure 13 (a) is a vertical view, and Figure 13 (b) is a side view.Figure 14 is that two sleeve shape wave welding head of ultrasonic wave are used in expression, and the corner portion of container is carried out welding, thus the figure of the state of the size that extends in the longitudinal direction.Figure 15 is the extended figure of form of goods of size of expression, and Figure 15 (a) is the stereogram of seeing from the top, and Figure 15 (b) is the stereogram of seeing from the below, and Figure 15 (c) is the enlarged drawing of the ultrasonic fusing portion on the base.
At first, with reference to Fig. 9 the ultrasonic fusing main points of present embodiment are explained.Workpiece sheet 6a, both end faces of 6b to being configured in altogether on the operation post 200, had the junction surface J in gap in this formation.Striding junction surface J and sticking joint 8 again.Here, workpiece sheet 6a, 6b are working of plastics of identical material with joint 8.Wave welding head of ultrasonic wave 2 is positioned this joint 8 tops.At the leading section of this wave welding head of ultrasonic wave, have protuberance 3 and recess 4.The leading section of wave welding head of ultrasonic wave 2 is pushed against on the joint 8, and ultrasonic vibration, limit pressurization are carried out in the limit.
Various examples to wave welding head of ultrasonic wave explain.As shown in figure 10, the leading section at the round convex shape wave welding head of ultrasonic wave is provided with circular protuberance 3.Has criss-cross recess 4 on the protuberance 3 respectively again.By protuberance 3, recess 4 are located at two places respectively, leading section just forms concavo-convex.Generally speaking, the leading section of wave welding head of ultrasonic wave constitutes by forming irregular structure doubly.
Below, Figure 11 represents other round convex shape wave welding head of ultrasonic wave, its leading section is provided with circular protrusions 3.Has the recess 4 that constitutes by cross recess on the protuberance 3 respectively.Leading section is by being provided with protuberance 3 respectively and recess 4 forms concavo-convex everywhere.Generally speaking, the leading section of wave welding head of ultrasonic wave 2 constitutes by forming irregular structure doubly.
As shown in figure 12, the leading section of square convex wave welding head of ultrasonic wave has square protuberance 3 in many places.In addition, between protuberance 3, intersecting recess 4.Leading section becomes and is formed with by the square protuberance 3 of many places and is centered around the concavo-convex structure that recess 4 therebetween constitutes.
Figure 13 represents two sleeve shape wave welding head of ultrasonic wave.The leading section of wave welding head of ultrasonic wave has square protuberance 3 in many places.In addition, intersecting recess 4 between the protuberance 3.Leading section becomes and is formed with by the square protuberance 3 of many places and is centered around the concavo-convex structure that recess 4 therebetween constitutes.The leading section of this wave welding head of ultrasonic wave is the structure that sleeve portion 5 launches to both sides, and the behind of this sleeve portion has the portion of dodging 51.
Figure 14 represents to use two sleeve shape wave welding head of ultrasonic wave, and welding, the state of the size that extends are in the longitudinal direction carried out in the bottom surface of container piece and top etc.On operation post, that each section of container piece 7a, 7b, 7c that cuts into necessary length is involutory.Then, at the position that section is involutory, form junction surface J continuously with gap via 73 of bottom surface 71, the sidewalls of container piece and base 72, top 74.Mode with the junction surface J that strides across these container piece is sticked joint 8.Here, container piece 7a, 7b, 7c and joint 8 are identical working of plastics.Two sleeve shape wave welding head of ultrasonic wave 2 are positioned on this joint 8.The leading section of this wave welding head of ultrasonic wave is provided with protuberance 3, recess 4.This wave welding head of ultrasonic wave, its sleeve portion 5 launches to both sides, and the behind of this sleeve portion has the portion of dodging 51.At this, container piece has base 72 and top 74 at peripheral part up and down.Dispose joint 8 to stride across the mode that is formed at the junction surface J on this top 74, and carry out ultrasonic fusing.In addition, dispose joint 8 to stride across the mode that is formed at the junction surface J on this bottom surface 71.Because wave welding head of ultrasonic wave has the portion of dodging 51, so even wave welding head of ultrasonic wave is positioned the corner portion of the top 74 of container piece, wave welding head of ultrasonic wave can butt base 72 and counteract yet.In addition, show a plurality of joints 8, the vestige after concavo-convex trace 9 expression weldings finish in the mode that strides across the junction surface J that bottom surface 71 and top 74 had.
As above, constitute, below its effect is described.
When ultrasonic fusing, the J place, junction surface of container piece 7a, 7b, 7c and each joint 8 produces frictional heat, and each container piece and joint 8 are fused to together.Because joint is identical material with each container piece, fusion each other, welding is not so which side can be peeled off from the junction surface.Wave welding head of ultrasonic wave 2 is metal, and for example material is an aluminium.Here,, do not overlap owing to be that the section separately of container piece 7a, 7b, 7c is involutory, so the finished material rate height at junction surface.
Have the wave welding head of ultrasonic wave of circular and square protuberance, the protuberance shape is not obvious to the difference of the influence of adhesive strength.Importantly the wave welding head of ultrasonic wave front end is to the degree of nipping of the plastic components that has softened.The dark more then bond strength of nipping is high more.Round convex shape wave welding head of ultrasonic wave shown in Figure 11 is suitable for elongated banded plastic components or the joint between the goods.Square convex wave welding head of ultrasonic wave shown in Figure 12 is suitable for the plastic components of wide cut or the joint between the goods.
Two sleeve shape wave welding head of ultrasonic wave, as shown in figure 13, because of being provided with the portion of dodging 51, so, when limit portion carries out welding, can avoid wave welding head of ultrasonic wave to collide the top 74 first-class obstacles of container piece, so use easily in corner portion to container piece.When carrying out welding, the front end protuberance 3 of wave welding head of ultrasonic wave and the weld mark of recess 4 have been formed, promptly concavo-convex trace 9.The leading section of this expression wave welding head of ultrasonic wave is nipped in the joint 8, and, joint with container piece fuse mutually, welding.Again, container piece 7a used herein, 7b, 7c are after the end face or both ends of the surface cut-out removal with the container standard part, the more involutory welding of each section are formed.As required, with the involutory in the longitudinal direction ultrasonic fusing that carries out of a plurality of container piece, thus, can obtain the longer vessel prepd of lateral dimension 7.
Figure 15 represents the example of vessel prepd 7 of the size that extended in the longitudinal direction of present embodiment.Shown in Figure 15 (a), Figure 15 (b), it is involutory to cut into container piece 7a, the 7b section separately of suitable length from vessel prepd.At the involutory position of these sections, form junction surface J continuously with gap via bottom surface 71, sidewall 73 and base 72, the top 74 of container piece.And, also dispose each joint 8 at each position in the mode that strides across this connector portions J.That is, set joint 8, and welding is carried out in butt joint 8 and top 74 in the mode that strides across the junction surface J that is formed on the top 74.In addition, set joint 8, again, also set joint 8, and welding is carried out in syncephalon 8 and bottom surface 71 or sidewall 73 in the mode that strides across the junction surface J that is formed on the sidewall 73 in the mode that strides across the junction surface J that is formed on the bottom surface 71.Again, shown in Figure 15 (c), set joint 8, and syncephalon 8 and base 72 are carried out welding in the mode that strides across the junction surface J that is formed on the base 72.Also to stride across the mode of each junction surface J, on each position on the joint 8, expressed the concavo-convex trace 9 that welding finishes.The leading section joint 8 of nipping of this expression wave welding head of ultrasonic wave, and joint and container piece fusion, welding, solidified.Except that the bottom surface of container piece, sidewall, on top, on the bottom side portion, joint 8 is also with container piece fusion, welding, therefore, the bond strength of vessel prepd 7 improves.Particularly carrying out on the base 72 under the situation of ultrasonic fusing, the welding by joint 8 and base 72, solidifying, comprising the bond strength of bottom surface 1 in interior bottom and strengthen, even under situation about weight being put in the vessel prepd 7, the bottom can not come off yet.
2 pairs of present embodiments are the container piece of spreading case shape in the longitudinal direction, thereby the situation of lengthening size is illustrated on desirable length or width, but, by using joint 8, even the plate object of corrugation paperboard, size also can extend on desirable length or width.
