Description

A kind of production method of improving plastic mast Crow ball

The present invention relates to the production method of a kind of improved plastic mast Crow (Takraw) ball.

Plutarch sieve is a kind of sports of rising in Thailand, however one band that but prevails in Southeast Asia.Employed main apparatus is a kind of Plutarch sieve ball in this motion, and the production method of traditional Plutarch sieve ball is to be processed into rattan.Plutarch sieve ball be shaped as round shape, its shape is similar to football, basketball etc.Yet the production method of Plutarch sieve ball but is different from the production method of other kind ball.In Chinese, Plutarch sieve ball is known as sepa takraw, and it means, and Plutarch sieve ball traditionally makes of rattan.In Thailand, Plutarch sieve refers to " blue shape thing (basket) ".Rattan system Plutarch sieve ball is the basket thing with the conglobate closure of cross one another rattan weaving, and this indigo plant shape thing is exactly Plutarch sieve.In fact the most handy 20 mutual interlacings of rattan of Plutarch sieve ball of Thailand form, and have 12 corresponding holes.

Traditional Plutarch sieve ball production method at first is that a rattan bar is cut into rectangular that 3～4mm is wide, 3～4mm is thick, then, these rattans is weaved into a circular boop twist, and the turn of its shape and 8～12 numbers of turn is similar.The width that how much depends on the rattan that uses of the number of turn also depends on the size of needed ball and the compactness extent of final formation ball simultaneously.Recently, Plutarch sieve ball of weaving into or being made into do not adopt around method, but rattan is carried out cramping with large-scale anchor clamps, make rattan mutually around being squeezed into a ball, the ball that this is squeezed into is handled with coconut oil then, prolonging its storage life, otherwise this ball soon will be dry, become fragile, split and lose its serviceability, perhaps this ball is corroded by insect, such as being corroded or the like by termite.

The quality of rattan system Plutarch sieve ball depends on the quality of rattan and the method for braiding.The rattan of dissimilar and all ages and classes is to producing a very large impact with this quality as raw-material sepa takraw, the normally manual operations of the weaving method of tradition sepa takraw, therefore, the performance characteristic of sepa takraw, such as: the size of the ball that each is made, weight, depend on weaver's qualification and weaver's mental state to a great extent around property, compactness, expected life, resilience or the like performance.So the production efficiency of sepa takraw is very low, because the raw-material quality of sepa takraw and weaver's difference cause the oeverall quality of sepa takraw to produce very big fluctuation.Further, the braiding of Plutarch sieve sepa takraw still belongs to the villagers' of hamlet homecraft skill hobby, do not set up a common entity and management organization and make the production standardization of sepa takraw and control its quality, promptly do not form an entity and adopt modern production process.

Plutarch sieve ball is to form with six roots of sensation band (band) interlacing, every similar turn of band in traditional Plutarch sieve ball with 8～12 circles, the two ends of band are open, these bands are clamp-oned and fill in below the contiguous band on the crosspoint, the number of turn of band is many more, weaver's workload is big more, makes the braiding process become difficulty greatly with more complicated.Therefore, adopt traditional weaving method to cause low and its quality of very difficult control of production efficiency of sepa takraw, especially adopt traditional weaving method be difficult to the size, weight of control such as sepa takraw, around degree, finally make the quality such as density of ball.

The deforestation problem also is the hidden danger that Plutarch sieve ball is produced, in addition in Southeast Asia one band, rattan also becomes and lacks rarely, at that band, rattan is very abundant originally.Rattan can be used for producing the more product of high additive value, for example, makes cane furniture.In any case, be used to produce rattan furniture rattan and be not suitable for producing sepa takraw, its reason is that the former is too hard and too coarse.Recently the suitable raw material that are used to the sepa takraw produced are many hardly.

Because the quality and the performance inconsistency of natural rattan system sepa takraw are very big, and the motion of Plutarch sieve ball is not popularized, also be difficult to worldwide promote the motion of Plutarch sieve ball.The intrinsic defective of Plutarch sieve ball is that rattan system Plutarch sieve ball is harder, so suppress the interest that the beginner plays Plutarch sieve ball.Undoubtedly, if Plutarch sieve ball does not carry out any improvement or do not carry out any new method for producing, so, Plutarch sieve ball and the motion of Plutarch sieve will be doomed to become extinct.

The purpose of the invention of plastic mast Crow ball is to utilize modern technology to protect this motion, makes topmost instrument-Plutarch sieve ball standardization of this motion and improves its quality.

Utilize plastic extruding forming method extrusion plastic section bar in order to imitated rattan, the weaving method that utilizes traditional Plutarch sieve sepa takraw can guarantee the stable high-quality of plastic mast Crow ball not increasing under the condition of cost.Because plastic mast Crow ball adopts plastic resin and extrusion method, make it contrast natural rattan and have the quality of uniformity more and the shape of cross section uniformly, yet, the production efficiency of traditional Plutarch sieve ball and inherent quality Control still are not resolved, it is the performance characteristic of ball, such as: the size of ball, weight, around degree and finally make compactness of ball or the like, still depend on weaver's qualification and weaver's mood to a great extent.

Since plastics were taken the Crow ball and are introduced into, it was based on the notion of closing hoop and disagree with the turn notion at beginning of traditional sepa takraw.Each band of described plastic mast Crow ball is looked at as one and closes hoop, and each band contains two edge strips and one central bars arbitrarily.These each end is joined together to form and closes hoop.

The common flat edge strip that adopts injection molding forming method to produce with straight edge, or as shown in Figure 1, a side of edge strip is for waiting radius convex edge, and opposite side is sine-shaped edge.When these edge strips of braiding, surperficial 1 direction is outside, and the back side 3 directions are inside.Side-looking Figure 2 shows that the flat shape of the side of general edge strip.Shape when the two ends of the outside edge strip in surface are coupled together as shown in Figure 3, this edge strip form a closure truncated cone shape hoop and become the part of sphere, it is as the primary structure of ball.The physical property of the ball that the shape of hoop and the decision of the physical property of the resin that uses are finally made.The plastic mast Crow ball that changeable injection molding forming method helps to produce is deacclimatized various dissimilar sporters' demand, as beginner, amateur, professional athlete or the like.Adapt to desired performance by shape and the selection suitable plastic raw material that change edge strip, and, can make each edge strip reach submillimeter precision by using high-precision mould and high-precision plastic injection equipment.Like this, before ball braiding, just being guaranteed of ball around property, compactness.

As shown in Figure 2, central bars be one stretch, plastic strip narrow, flat-shaped and that have straight edge, its injection moldable or extrusion molding also are cut into suitable length.When braiding, surperficial 1 direction is outside, and the back side 2 directions are inside.

Typical plastics Plutarch sieve ball has the band of six roots of sensation weave in, and every band has two edge strips and a central bars.This ball has 12 holes and 20 intertwined points.Before the present invention, plastic mast Crow ball weaves based on the principle with complete band braiding.First band is the hoop of a closure being formed by two edge strips and central bars, by anchor clamps these three bar clampings come together to finish.Second same band is woven on first band, and this step is easy to, because of only once intersecting.The 3rd same band sequentially is woven on the first two root band, in this step braiding process, intersection is arranged twice, intersection is arranged five times when then a band being woven up again, by that analogy, again next root band sequentially is knitted in the established structure in front, is knitted into up to six roots of sensation band and forms a ball of finally making.Increase along with the band number, the difficulty of braiding increases, because along with the number of times that intersects is more and more many, it is more and more tight that ball also just becomes, therefore six roots of sensation band is a band of the most difficult braiding, can only experienced weaver the 5th and six roots of sensation band could be woven into, this needs special-purpose instrument and special training just can finish.Weaver's in type structure of high speed of having to, promptly, the sine-shaped trough that is close to edge strip on each the root band on all intertwined points mutually must suitably be connected with the sine-shaped trough of edge strip on other band, otherwise, stay enough spaces just can for last root band, that is, last root band can not be enrolled in the ball.This is a power of enforcement process, and, if weaver's strength is too big, plastic strip can be damaged, and so, the quality of ball will go wrong.

In brief, have stable high-quality although close the plastic mast Crow ball of hoop than traditional rattan system Plutarch sieve ball, its production process is also greatly simplified, yet its braiding process still has foregoing difficulty.The present invention discloses a kind of new improved weaving method, use this method make the braiding of ball easier, faster.

The present invention utilizes the means of innovation to improve the weaving method of Plutarch sieve ball, not only improves the quality of ball but also the purpose of enhancing productivity thereby reach.

The present invention is with the method that increases edge strip quantity, rather than weaves the method for whole band with power of enforcement at every turn.At first whole ball is weaved into the basket thing of a closure with an edge strip in each band, then, on the structure that forms closed basket thing, a more other edge strip is woven into, then again central bars is woven on each band so that the structure of braiding is tighter.

The improved weaving method that the present invention discloses mainly is made up of four key steps, the steps include: to weave into our basket thing of opening by an edge strip on the every band; The basket thing of forming a closure again by an edge strip on the every band; Second edge strip is programmed in the every band; If every band is made up of three bars, in every band, insert central bars again, if the band of being made up of two bars is made plastic mast Crow ball, the 4th step can omit.

First step of the present invention is to weave into our basket thing of opening by an edge strip on the every band.This step comprises three step by step,, makes the edge strip hoop (as shown in Figure 3) of a closure that is; Framework (as shown in Figure 4) by five bar braidings; To be woven together (as shown in Figure 5) by the framework of five bar braidings and the edge strip hoop of Manufactured closure again.

Second step exactly on the basis of the basket thing that we of first step opens, forms the basket thing of the closure of being made up of edge strip on the every band.This step is actually a braiding process, and promptly we of every edge strip opens two ends bending downwards and link together, and is woven into braid with other edge strip.After whole five edge strips were coupled together, the basket thing of a closure had just formed (as shown in Figure 6).

The 3rd step is that second edge strip knitted on the every band.The basket thing of the closure of being made by second step of being made up of edge strip on the every band is as framework, sequentially weave in the every band second edge strip in the same way, the position of the straight or smooth lateral margin of each the root edge strip on the tightly close every band in the position of second straight or smooth lateral margin of edge strip, the two-end-point that we is opened connects together.After the braiding of whole six roots of sensation bands finished, the basket thing of the closure of being made up of two edge strips on the every band had just formed (as shown in Figure 7).

The 4th step is to insert central bars.The 3rd step by every band on the framework of the closed basket thing formed of two edge strips, central bars is being knitted between two edge strips that woven on the every band between existing two edge strips in the same way in proper order, the two ends that we opens with central bars link together, and joint moved on to below the band hide.After the braiding of whole six roots of sensation bands finished, complete Plutarch sieve ball had just formed (as shown in Figure 8).

Below in conjunction with drawings and Examples plastic mast of the present invention Crow ball is elaborated:

Brief Description Of Drawings:

Fig. 1 is an edge strip.

Fig. 2 is a central bars.

Fig. 3 is that the two ends with edge strip couple together and form closed edge strip hoop.

Fig. 4 forms a framework of being made up of five bars for five edge strips are overlapped successively.

The framework that Fig. 5 forms for closed hoop and five edge strips weaves the basket thing that we that form opens.

The basket thing of the closure that Fig. 6 is made up of an edge strip of every band.

The serve as reasons basket thing of the closure that two edge strips of every band form of Fig. 7.

Fig. 8 is for inserting complete Plutarch sieve ball that central bars forms.

The object of the present invention is to provide a kind of production method of improving plastic mast Crow ball, with the quality of satisfied raising ball and the requirement of production efficiency.

Every band on the ball of plastic mast Crow can be understood that the hoop of a closure, and just the notion with the turn at similar we of traditional rattan system Plutarch sieve different at beginning for these.Every band is made up of the bar of two or three closures.Six roots of sensation band is woven into the basket thing of the closure of a sphere, that is, and and Plutarch sieve ball (as shown in Figure 8).On the plastic mast Crow ball that three bars by every band are woven into, every band is made up of two edge strips and a central bars.On Plutarch sieve ball that two bars by every band are woven into, there is not central bars.

In the following embodiments, the present invention is woven into a complete plastic mast Crow ball with the method that every band increases the edge strip radical with these bands, rather than with traditional method that a complete band is forced woven plastics Plutarch sieve ball.Adopt this new weaving method, the quantity of the bar of every band increases progressively gradually on Plutarch sieve ball, that is, be not to weave simultaneously.For the first time around the time, only be woven into the basket thing of a closure by an edge strip of every band.For the second time around the time in first edge strip of second edge strip next-door neighbour is programmed on the every band.For the third time around the time again central bars is inserted on the every band in the same way.Adopt braiding that this weaving method that increases progressively edge strip makes the 5th and six roots of sensation edge strip quite easily, quick, the structure of the ball that is woven, the structure of promptly not finishing ball are loose in the meantime.Because two edges of central bars all are straight, central bars can be woven in the said structure not difficultly, even last root central bars is woven into also not difficult.In fact, after central bars is knitted in the said structure, make Plutarch sieve ball of braiding become fastening.

In an embodiment of the present invention, the production method of improving plastic mast Crow ball can be divided into four key steps,, is woven into our basket thing of opening by an edge strip of every band that is; Be organized into the basket thing of a closure again by an edge strip of every band; Second edge strip is made on the every band of basket thing of above-mentioned closure; Again central bars is inserted on the every band.

Because plastic mast Crow ball is spherical, so from each direction of ball all is identical, an inevitable problem of the present invention is to take up braiding where, first step of the present invention is that an edge strip by each band is woven into our basket thing of opening, and this step can be divided into following three processes again.

First process is exactly the edge strip hoop of a closure of preparation.Two end points that are about to edge strip connect into closed hoop (as shown in Figure 3).

Second process, five edge strips are woven together forms a framework of being made up of five bars (as shown in Figure 4).Begin the edge strip 1 with a horizontal positioned, its sinuous edge is away from the weaver.Then, edge strip 2 is ridden on the edge strip 1, be 108 ° of angles between the two.Edge strip 3 rides on the edge strip 2, and by that analogy, edge strip 4 rides on the edge strip 3, and edge strip 5 rides on the edge strip 4.Ride on the edge strip 4 and edge strip 5 is ends, the other end fill in edge strip 1 the other end below.Five frameworks that edge strip is formed, its center is a pentagon, its whole shape is similar starlike.If the sine-shaped edge direction of five edge strips inwardly also can form the framework of being made up of five edge strips.Yet preferred embodiment of the present invention is that the sinusoidal edge direction is outside, forms a pentagon of being made up of smooth edge in the inboard of central authorities, and this will make braiding subsequently easier.

Last process of first step is that the edge strip hoop of the closure that the framework that forms on the basis of second process and first process are made is woven together; The similar five-pointed star of its shape (five-branch star).Our the basket thing (as shown in Figure 5) opened that is woven into by an edge strip of each band.When second process by five frameworks that are woven into, the sinusoidal edge direction on its edge strip is outside, the sinusoidal edge direction of the edge strip hoop of the closure that is woven together with it is downward.On the contrary, if the sinusoidal edge direction of the framework that second process is woven into by five edge strips is inside, the direction at the sinusoidal edge of the edge strip hoop of the closure that is woven together with it so is upwards.In most preferred embodiment of the present invention, the sinusoidal edge of closed edge strip hoop is downward direction braiding.

Second step is exactly the basket thing closure of on the basis of first step we being opened.At first, any of five edge strips of the basket thing that we is opened couples together two end points.Secondly, the edge strip at our adjacent beginning must weave with the firm edge strip that forms closed hoop before its two ends connect, successively five whole edge strips are coupled together, like this, the basket thing of the closure of being weaved into by an edge strip of every band has just formed (as shown in Figure 6).

The 3rd step is woven into second edge strip on the every band exactly.The basket thing of the closure that an edge strip by every band that obtains from a last step is woven into is as a skeleton, straight or the smooth edges of existing first edge strip is close to placement mutually on the straight or smooth edges that second edge strip has a constant radius and the closed basket thing, and with weave into the identical method of closed basket thing by an edge strip of every band, sequentially second edge strip is programmed on the above-mentioned skeleton, the end points that we is opened links together again.After all the braiding of six roots of sensation band is finished, just formed the basket thing (as shown in Figure 7) of the closure of weaving into by two edge strips of every band.Because whole ball is still very loose, so more much easier than aforesaid pressure weaving method when weaving six roots of sensation edge strip.

The 4th step is to be woven on the basis of closed basket thing at two edge strips by every band, inserts a central bars again and makes a complete ball, and its insertion position is between every pair of edge strip on the every band, with fastening braid.This process is quite simple, and the weaver only follows the former style of edge strip and insert a central bars in the middle of edge strip, its two ends is coupled together to get final product then.

Also need improve a little final step, the tie point that is about to central bars moves on to and it is stashed below the contiguous band, and each joint on the ball is all hidden.For symmetry, tie point all has been hidden in the covering effect band mid portion below.After institute finished in steps, the structure of the ball that finally is woven into as shown in Figure 8.Ball is rounded and very fastening, and need not further to handle with the pincers tool.Also as traditional natural rattan system ball, need to handle with coconut oil.

Because the braiding process of plastic mast of the present invention Crow ball is to launch explanation, so its process seems simpler.The weaver can at a good pace weave.Utilize the production cost of plastic mast Crow ball of improved production method processing quite low, but stable high-quality is arranged than the ball of former pressure weaving method production.
