Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides an outer shell member for a cored braided packing;
Woven structures and braided structures are used to cover in-wall penetrating members such as signal lines and fluid transport pipes such as hoses, and are used as conduction shafts and flanged pipes that are required to be joined to other parts. The present invention relates to an apparatus for manufacturing a braided/woven composite structure and a method for manufacturing the same.

[Prior Art] Traditionally, bag-knitted braided structures have been used, for example, for outer shell members of cored braided packing, for covering in-wall penetrating members such as signal lines, and for covering fluid transport pipes such as hoses. It is well known that
This braided structure is manufactured by a well-known braiding machine.

[Problem to be Solved by the Invention] In a conventional braiding machine, a predetermined composition is obtained from a knitting yarn bobbin held on a plurality of yarn bobbin carriers moving along a clockwise braiding path on two bag-knitting braiding paths. from a knitting yarn bobbin that is unwound to a point and held in a plurality of other yarn bobbin carriers that move along a counterclockwise braiding path;
By intertwining the knitting yarns fed out at a predetermined composition point from both the inside and outside at the intertwining point, a bag-knitted structure A is manufactured by braiding the knitting yarns a1 and a2 as shown in FIG. 17.

However, since the conventional bag-knitted structure A is generally a single interlaced braid in which the knitting yarns a1 and a2 are intertwined from the inside and outside, there is a slight disadvantage in terms of strength depending on the type of knitting yarn. Sufficient cases arise.
Therefore, as shown in FIG. 18, the circumferential yarn B is perpendicular to the axis C1 of the bag-knitted structure A and intertwines with the knitting yarns a1 and a2 in the circumferential direction.
The knitting yarns a1 and a2 are made into circumferential yarns by letting out and braiding them, or by making the penetrating yarns C parallel to the axis C1 and penetrating the braided layer made of the knitting yarns a1 and a2 radially in and out of the diameter. There is a need to manufacture a reinforced bag-knitted structure reinforced by at least one of the threads B and the penetrating threads C.

However, there is no device for braiding the circumferential thread B into the knitting threads a1, a1, and the braiding of the circumferential thread B depends on the manual work of an operator. Therefore,
The problem is that productivity is low and quality varies.

On the other hand, in order to apply the aforementioned bag-knitted structure or reinforced bag-knitted structure to other members, such as a conduction shaft or a pipe, it is desirable to form flanges that extend radially outward at both axial ends. However, since this cannot be desired, a separate intermediate member for joining is required for joining with other members, which has the disadvantage of complicating the structure and making joining work extremely difficult.

The present invention has been made in view of the above circumstances, and includes not only a bag-knitted structure made of a single interlaced braid, but also a structure in which at least one of the circumferential threads and the penetrating threads is braided to improve the strength. Manufacturing a reinforced bag knit structure, manufacturing a braided/woven composite structure exhibiting a composite structure of the reinforced bag knit structure and a tubular weave portion, at least a tubular weave structure, a bag knit structure, or a reinforced bag knit structure The object of the present invention is to provide an apparatus for manufacturing a braided structure and a composite braided/woven structure that can continuously form a brim-like woven structure at one end in the axial direction, and a method for producing the same.

[Means for Solving the Problems] In order to achieve the above object, a manufacturing apparatus according to the present invention includes: a pair of plates concentrically arranged facing each other and swingable about an axis; a drive stop mechanism that alternately swings the plate forward and backward in different directions at predetermined swing angles and stops at a position corresponding to each swing angle; and the spindles are disposed at equal intervals in the circumferential direction on the circumference defined by the same radius of curvature, and the pair of plates has a discrepancy of one pitch in the circumferential direction of the spindles. a knitting yarn bobbin which is held rotatably and removably inserted at intervals, and when both plates are stopped, the knitting yarn is transferred to the opposing spindle of the other plate and pays out the knitting yarn to the composition point of the axial center between the two plates; and the drive; a pull-out moving mechanism that pulls out and moves the braided portion braided at the composition point in the axial direction by swinging both plates at a predetermined angle by the mechanism and paying out the knitting yarn while the knitting yarn bobbin moves to the other plate; Along the turning trajectory around the point, the expanded part of the knitting yarn that has already been paid out from the knitting yarn bobbin to the composition point is turned when both plates are stopped, and the circumferential yarn is paid out with a predetermined tension and wound in the circumferential direction. a circumferential yarn bobbin that is held in a reciprocating state when both plates are stopped along a movement locus extending in a radial outward direction from the composition point, and during braiding, pays out a penetrating yarn that sequentially passes through the interlacing points of the knitting yarn. and a penetrating yarn bobbin that extends in a radial direction outside the radius and becomes a part of the knitting yarn during weaving, and the drive stop mechanism swings the pair of plates alternately forward and backward at a predetermined angle in different directions. and the transition of the knitting yarn bobbin to the opposing spindle of the mating plate when the drive stop mechanism is stopped, as well as the braiding of the bag knitting structure by cooperation with the drawer of the drawer moving mechanism, and the circumferential yarn and penetration that are synchronous with this braiding. Braiding of the reinforced bag knitting structure by letting out at least one of the yarns, the knitting yarn being paid out from the knitting yarn bobbin while being sequentially transferred to at least the spindle of the mating plate when the drive stop mechanism and the drawer moving mechanism are stopped, and the knitting yarn A part of the weaving part with the circumferential thread that is let out along a swirling trajectory that changes in the radial direction through the widening part of the weaving part makes it possible to weave a tubular weave structure or a brim-like weaving structure that extends in the radial direction. It is.

In addition, in order to achieve the above object, the manufacturing method according to the present invention provides a method for producing plates arranged at equal intervals in the circumferential direction on opposing surfaces of a pair of plates facing each other and arranged so as to be swingable around an axis. A knitting yarn bobbin, which is rotatably held on the spindle and can be inserted and removed at every interval of the spindle, is disposed between the two plates by one pitch in the circumferential direction, and when the two plates are stopped, the knitting yarn bobbin is attached to the other side. At the same time, by actuating the drive stop mechanism, both plates are alternately swung in forward and reverse directions in different directions at a predetermined oscillation angle, and the knitting yarn bobbin is positioned between the two plates. The knitting yarn is fed out to the composition point of the axial center, and the braided body braided by the knitting yarn is pulled out and moved by the pull-out moving mechanism to execute the braiding of the bag-knit structure, and to synchronize with this bag-knitting braid. Then, when both plates are stopped, the expanded portion of the knitting yarn, which has already been paid out from the knitting yarn bobbin to the composition point, is rotated along the outer circumferential turning trajectory of the composition point, and is rotated at a predetermined tension from the circumferential yarn bobbin. Reinforced bag-knit structure by composite braiding of at least one of the circumferential yarn being let out and the penetrating yarn being paid out from the through-thread bobbin that reciprocates when both plates are stopped along a locus of movement extending in the radial direction from the composition point. The knitting yarn drawn out from the knitting yarn bobbin and the expanded portion of this knitting yarn are transferred in sequence to at least the spindle of the mating plate by stopping each of the drive stop mechanism and the pull-out moving mechanism, and the expanded portion of the knitting yarn is moved in the radial direction. A brim-like woven structure extending in the radial direction is woven by weaving with a circumferential thread that is paid out from a circumferential thread bobbin along a turning orbit that moves along a rotating orbit.

[Function] According to the manufacturing apparatus according to the present invention, the drive stop mechanism is actuated to swing the pair of plates alternately forward and backward in different directions at a predetermined swing angle, and the drive stop mechanism is stopped. When both plates are stopped, the knitting yarn bobbin is transferred to the opposing spindle of the other plate. By continuing the operation, the knitting yarn is unwound from the knitting yarn bobbin at the composition point of the axial center between the two plates. The yarns are braided, and the braided portion is pulled and moved by a pull-out moving mechanism, thereby making it possible to braid a bag-knitted structure.

Then, when both plates stop when the knitting yarn is knitted by the aforementioned operation, the expanded portion of the knitting yarn that has already been paid out from the knitting yarn bobbin to the composition point is rotated along the outer circumferential orbit of the composition point. By paying out the circumferential yarn from the circumferential yarn bobbin with a predetermined tension, the circumferential yarn is braided into the bag knitting structure perpendicularly to the axis C1 and intertwined with the knitting yarn in the circumferential direction. A reinforced bag-knitted structure can be manufactured, and instead of paying out the circumferential yarn, the yarn is sequentially penetrated in the vicinity of the composition point in the radial direction and outside along the locus of movement extending from the composition point in the radial direction. By letting out the penetrating yarn from the penetrating yarn bobbin, it is possible to manufacture a reinforced bag-knitted structure in which the penetrating yarn is radially penetrated through the bag-knitted structure and braided. Moreover, by using both the circumferential thread and the penetrating thread, a reinforced bag-knitted structure reinforced by both the circumferential thread and the penetrating thread can be manufactured.

Furthermore, following the bag knitting braid or the reinforced bag knitting braid by the above-mentioned operation, while both plates and the pull-out moving mechanism are stopped, at least the knitting yarn that is being paid out from the knitting yarn bobbin is sequentially transferred to the spindle of the other plate. By letting out the circumferential yarn along a turning locus that varies in the radial direction while meandering, it is possible to manufacture a brim-like woven structure that extends in the radial direction at the axial end of the bag-knitted structure.

Further, according to the manufacturing method of the present invention, the drive stop mechanism is actuated to swing the pair of plates alternately forward and backward in mutually different directions at a predetermined swing angle,
By stopping the drive stop mechanism, both plates are stopped, and by continuing the operation of transferring the knitting yarn bobbin to the opposing spindle of the other plate at the time of stopping, the composition point of the axial center between both plates is Since the knitting yarn paid out from the knitting yarn bobbin is braided and the braided portion is pulled and moved by the pull-out moving mechanism, the bag-knitted structure can be easily manufactured. When both plates are stopped, the expanded portion of the knitting yarn that has already been paid out from the knitting yarn bobbin to the composition point is rotated along the outer circumferential turning trajectory of the composition point, and the yarn is rotated from the circumferential yarn bobbin with a predetermined tension. Since the circumferential yarn is let out, the circumferential yarn is braided perpendicularly to the axis C1 of the bag knitting structure and intertwined with the knitting yarn in the circumferential direction.
A reinforced bag-knitted structure can be easily manufactured. In addition, instead of letting out the circumferential yarn, by letting out the through yarn from the through yarn bobbin along a locus of movement extending radially outward from the composition point, the through yarn is radially parallel to the axis of the bag-knitted structure. Braided through the
A reinforced bag-knitted structure can be easily produced. Of course, by using a combination of letting out the circumferential yarn and letting out the penetrating yarn, it is possible to easily manufacture a reinforced bag-knitted structure reinforced by both the circumferential yarn and the penetrating yarn. Furthermore, following the bag knitting braid or the reinforced bag knitting braid by the above-mentioned operation, while both plates and the pull-out moving mechanism are stopped, at least the knitting yarn that is being paid out from the knitting yarn bobbin is sequentially transferred to the spindle of the other plate. By letting out the circumferential yarn along a turning trajectory that varies in the radial direction, it is possible to easily manufacture a brim-like woven structure that extends in the radial direction at the axial end of the bag-knitted structure. .

By this, the first
Flange-shaped woven structure 103 with the weaving pattern shown in Fig. 4
can be woven.

In each of the embodiments of the weaving structure 103, it is explained that the circumferential thread 8A is unwound from the circumferential thread bobbin 8 along a turning trajectory in which the diameter becomes larger in the radial direction, but as shown in FIG. Alternatively, the flange-like weaving structure 103 may be woven by letting out the circumferential thread 8A from the circumferential thread bobbin 8 along a spiral orbit. Further, it is explained that when braiding the reinforced bag knitting structure 101, the expanded portions of the knitting yarns 5a and 5b are turned to let out the circumferential yarn 8A from the circumferential yarn bobbin 8.

By braiding at least one of the circumferential yarn or the penetrating yarn and the knitting yarn, a reinforced bag-knitted structure with improved strength can be manufactured, thereby improving productivity and quality. Furthermore, since a highly strong brim-like woven structure can be woven continuously at least at one axial end of the bag-knitted structure or the reinforced bag-knitted structure, the bag-knitted structure or the reinforced bag-knitted structure can be weaved by automation. For example, when joining other parts as a conduction shaft or pipe, the brim-like woven structure can be used as a high-strength flange, so it can be easily and firmly joined without using a conventional intermediate member for joining. can do.

The knitting yarn bobbin, which has a discrepancy of one pitch and is rotatably held and can be inserted and removed at every spindle interval, is transferred to the opposing spindle of the mating plate when both plates are stopped, and the drive stop mechanism is activated. The plates are alternately oscillated forward and backward in different directions at a predetermined oscillation angle, and the knitting yarn is paid out from the knitting yarn bobbin to the composition point of the axis located between the two plates, and the knitting yarn is The braided body is pulled out and moved by the pull-out moving mechanism to perform braiding of the bag-knitted structure, and in synchronization with this bag-knitted braid, the braided body is moved along the outer circumferential orbit of the composition point, The expanded part of the knitting yarn being paid out from the knitting yarn bobbin to the composition point is rotated when both plates are stopped, and the circumferential yarn being paid out from the circumferential yarn bobbin with a predetermined tension, and the circumferential yarn being paid out from the composition point in the radial direction outward from the composition point. The reinforcing bag knitting structure is braided by composite braiding with at least one of the penetrating yarn paid out from the penetrating yarn bobbin that reciprocates when both plates are stopped along the extending movement locus, and the drive stop mechanism and the drawer moving mechanism. The knitting yarn is paid out from the knitting yarn bobbin while stopping each of the knitting yarns, and the knitting yarn is paid out from the knitting yarn bobbin while sequentially transferring to at least the spindle of the mating plate. A method for producing a single braided structure, a single woven structure, or a composite braided/woven structure, which comprises weaving a radially extending collar-like woven structure by weaving with circumferential threads. .
