Abstract
A braiding apparatus includes a platform, a base plate, a core unit, a transmission unit, a track assembly, and strand carriers. The track assembly is divided into two braiding track groups each provided with transmission discs. The transmission discs of both braiding track groups are sequentially connected to define two braiding routes. The strand carriers shuttle on both braiding routes respectively and incessantly. Two intersection points are defined when the two braiding routes intersect. Accordingly, carrier strands fed by the strand carriers are wound around a core strand fed by the core unit while shuttling incessantly and are interwoven with each other while passing through the two intersection points during the incessant shuttling motion, thereby wrapping a multi-convolutional braided layer around the core strand to complete a rope. Each convolution of the braided layer has two crossing points, which increases the practicability of the rope.
Description
- This invention relates to a braiding apparatus and relates particularly to a braiding apparatus having a track assembly capable of executing a two-point interweaving operation.
- Referring to
FIG. 1 throughFIG. 3 , aconventional braiding apparatus 1, as briefly shown, includes aplatform 11, abase plate 12 disposed on theplatform 11, acore unit 13 centered on thebase plate 12 for feeding a core strand “a”, atransmission unit 14 disposed below thebase plate 12, atrack unit 15 arranged on thebase plate 12, and a plurality ofstrand carriers 16 shuttling on thetrack unit 15 for feeding carrier strands “c”. Thetrack unit 15 includes a plurality of rotatingdiscs 151 arranged around thecore unit 13 and connected one after another to assume a circular arrangement. Each rotatingdisc 151 includes a plurality ofnotches 152 for carrying thestrand carriers 16. Anintersection 153 is formed between any two adjacent rotatingdiscs 151 under the circular arrangement of thetrack unit 15, which thereby defines an internal route “b1” and an external route “b2”. - When the
transmission unit 14 is actuated, thestrand carriers 16 move under a guiding motion of thetrack unit 15. In other words, the rotatingdiscs 151 cooperate with thenotches 152 to convey thestrand carriers 16 so that thestrand carriers 16 travels between the rotatingdiscs 151 through theintersections 153 for shuttling on the internal route “b1” and the external route “b2” continuously. Meanwhile, each carrier strand “c” fed by eachstrand carrier 16 is incessantly pulled in different directions under the continuous shutting motion of thestrand carriers 16. Therefore, the carrier strands “c” are crowdedly interwoven with each other to execute a crowded braiding operation whereby a braided layer is formed. The braided layer is provided with multiple convolutions and wrapped around the core strand “a”, thereby producing acomplete rope 2 shown inFIG. 3 . During the crowded braiding operation, each convolution of the braided layer formsmultiple crossing points 21 close to each other when the carrier strands “c” and other carrier strands “c” cross each other, as illustrated inFIG. 2 in which only the front view of the braided layer is shown. - Because the
intersections 153 are formed based on the circular arrangement, the braided layer formed by interweaving the carrier strands “c” shows a crowdedly-interwoven pattern wound around the core strand “a”. However, the application of this crowded pattern is still limited. For example, toomany crossing points 21 are formed because of the above interweaving mode, with the result that too many interstices are left between the carrier strands “c” and the core strand “a”, and the contact surface between the carrier strands “c” and the core strand “a” is also reduced. These conditions affect the heat conduction and limit the efficiency of dissipating heat while using therope 2 in terms of heat dissipation. Thus, the conventional crowdedly-interwoven pattern formed by the crowded braiding operation is difficult to meet practical demand and still needs to be improved. - An object of this invention is to provide a braiding apparatus capable of generating a two-point interweaving operation, a track assembly of which defines a first braiding route and a second braiding route meeting at two intersections whereby a complete rope with a braided layer different from the conventional crowded pattern is produced, especially each convolution of the braided layer provides two crossing points to increase the practicability of the rope.
- The braiding apparatus of this invention includes a platform, a base plate disposed on the platform, a core unit adapted to supply a core strand, a transmission unit disposed below the base plate, a track assembly arranged on the base plate, and a plurality of strand carrier shuttling on the track assembly and adapted to supply carrier strands. The track assembly includes a plurality of transmission discs disposed on the base plate and driven by the transmission unit. Each transmission disc has a plurality of notches formed thereon and adapted to carry the strand carriers. The transmission discs are connected to each other to thereby divide the track assembly into a first braiding track group and a second braiding track group. Both of the first braiding track group and the second braiding track group are arranged around the core unit when the core unit is centered on the base plate, and the first braiding track group is encircled by the second braiding track group. The transmission discs of the first braiding track group and the transmission discs of the second braiding track group are sequentially connected to each other, thereby defining a first braiding route and a second braiding route which meet to form two intersections. The two intersections are spaced at 180 degrees from each other. The transmission discs on the first braiding route and the transmission discs on the second braiding route are rotated in different directions, namely in opposite directions. According to the above, the strand carriers are allowed to shuttle on the first braiding route and the second braiding route respectively and incessantly to execute an incessant shuttling motion whereby the core strand is wrapped in the carrier strands fed by the strand carriers. During the incessant shuttling motion, the carrier strands are interwoven with each other on an outer surface of the core strand when the strand carriers travel through the two intersections. Therefore, a full braided layer with multiple convolutions is created and wrapped around the core strand to thereby complete a braided rope, especially each of the convolutions has two crossing points to provide the rope with a special braided arrangement different from the conventional crowdedly-interwoven pattern. This special braided arrangement can promote the practicability of the rope.
- Preferably, in one preferred embodiment, the first braiding route and the second braiding route intersect to form the two intersections, thereby assuming a state of double interlinking circuits.

transmission discs braiding track group 351 and the secondbraiding track group 352 are sequentially connected to each other to thereby define different braiding routes D1, D2. For example, two sides of onetransmission disc 351A are respectively connected to twotransmission discs 352A which are adjacent to thistransmission disc 351A, andother transmission discs 351A are also adapted to the same connecting mode. Meanwhile, thetransmission discs 352A are connected in sequence. The above shows an alternate connection, so a first braiding route D1 (shown inFIG. 5 ) and a second braiding route D2 (shown inFIG. 6 ) can be defined on thewhole track assembly 35, thereby allowing a group ofstrand carriers 36 to shuttle on the first braiding route D1 continuously and simultaneously allowing another group ofstrand carriers 36 to shuttle on the second braiding route D2 continuously. Thus, the incessant shuttling motion on both of the first braiding route D1 and the second braiding route D2 is executed. - The first braiding route D1 and the second braiding route D2 intersect or meet each other. Preferably, it is assumed that the first braiding route D1 is defined as a circuit having a first circuitous style while the second braiding route D2 is defined as another circuit having a second circuitous style, and the two circuits not only sit next to each other but also cross partially to assume a chain-like interlinking state, namely double intersecting circuits as shown in
FIG. 7 in which the bold or thick line represents the first braiding route D1, and the thin line represents the second braiding route D2. Thus, when the first braiding route D1 and the second braiding route D2 meet to show the chain-like connection, two intersections D3, circled parts shown inFIGS. 4 and 7 , are formed, and the two intersections D3 are located in opposite directions to be spaced at 180 degrees from each other. In other words, if a reference line from one intersection D3 to thecore unit 33 is defined, and the other reference line from the other intersection D3 to thecore unit 33 is also defined, the two references lines are in a line so that the two intersections D3 are spaced from each other by 180 degrees. In addition, the direction of rotating thetransmission discs 351A on the first braiding route D1 is different from the direction of rotating thetransmission discs 352A on the second braiding route D2, as arrowed inFIG. 7 . Accordingly, during the shutting motion of thestrand carriers 36 on both braiding routes D1, D2, the carrier strands “B” fed by thestrand carriers 36 cross to be interwoven with each other when thestrand carriers 36 pass through each intersection D3. The interweaving operation of the carrier strands “B” occur in the two intersections D3, with the result that around the core strand “A” is wrapped a braided layer, each convolution of which only has two crossing points 41. - The operation of this invention is described with the aid of
FIG. 4 andFIG. 7 . Firstly, a start end of a core strand “A” of thecore unit 33 is fed to a strand collector (not shown), and a start end of a carrier strand “B” of eachstrand carrier 36 is also fed to the strand collector. Then, thebraiding device 3 transmits power to operate thetransmission unit 34, and the rotations of thetransmission discs transmission unit 34 is in action. During the rotations of thetransmission discs strand carriers 36 shuttle on the first braiding route D1 and the second braiding route D2, and each carrier strand “B” subjects an outer surface of the core strand “A” to winding and interweaving so that the core strand “A” is wrapped in the carrier strands “B”. As for example arrowed inFIGS. 4 and 7 , a group ofstrand carriers 36 located on the first braiding route D1 can only shuttle on the route D1 incessantly, and another group ofstrand carriers 36 located on the second braiding route D2 can only shuttle on the route D2 incessantly. Accordingly, the carrier strands “B” are continuously wound around the outer surface of the core strand “A” because of different shuttling directions of thestrand carriers 36 on both routes D1, D2. Meanwhile, when thestrand carriers 36 travel through the two intersections D3 in sequence during the aforementioned shutting motion, the carrier strands “B” cross to be interwoven with each other on the outer surface of the core strand “A” . Thus, the shuttling motion of thestrand carriers 36 causes a winding and interweaving operation, and the winding and interweaving operation between the carrier strands “B” and the core strand “A” is continuous to provide an incessant braiding action whereby arope 4 is finally produced. Therope 4 is then collected by the strand collector for further use. InFIG. 9 , it shows that thecomplete rope 4 has a braided layer created by the winding and interweaving operation and provided with multiple convolutions or coils which are wound around the core strand “A”, and each convolution or each coil of the braided layer has two crossing points 41. The twocrossing points 41 are spaced from each other when each convolution is made, as illustrated inFIG. 8 where the front view of the braided layer shows onecrossing point 41 by a solid line, and the other circled part shown as a dotted line represents theother crossing point 41 formed on the back. - Regarding the braided layer as shown in
FIGS. 8 and 9 , it is apparent that the arrangement of the carrier strands “B” located on two sides of eachcrossing point 41 is unlike the conventional crowdedly-crossing arrangement shown inFIGS. 2 and 3 , and the aforementioned two-point interwoven arrangement contributes to a broad application of therope 4. For example, the braided layer featuring twocrossing points 41 on each convolution not only increases the contact surface between the carrier strands “B” and the core strand “A” but also reduces interstices formed between the core strand “A” and the carrier strands “B”, and these conditions promotes the heat conduction and facilitates an increase in the efficiency of dissipating heat while using therope 4 in terms of heat dissipation. Therefore, this special arrangement can produce arope 4 of good quality, and therope 4 can be widely applied to meet practical needs, thereby increasing the practicability. - To sum up, the braiding apparatus of this invention divides the transmission discs of the track assembly which are disposed around the core unit into a first braiding track group and a second braiding track group and also takes advantage of the connection between the above transmission discs to define a first braiding route and a second braiding route on which strand carriers can shuttle respectively and incessantly for executing an incessant braiding action, especially the two braiding routes meet to form two intersections. Carrier strands fed by the strand carriers are interwoven with each other when the strand carriers pass through the two intersections. Thus, a braided layer having two crossing points on each convolution is created and wrapped around an outer surface of a core strand. Finally, the incessant braiding action of the strand carriers around the core strand produces a complete rope with the special braided layer whereby the practicability of the rope is increased.
- While the embodiments are shown and described above, it is understood that further variations and modifications may be made without departing from the scope of this invention.
