An embodiment of the present invention will be described in detail with reference to the drawings.
1-13 is explanatory drawing of the process which shows the manufacturing method of the loop-shaped fiber rope of this invention.

  The loop-shaped fiber rope of the present invention is manufactured by a method called a cross rope sag-joining eye splice, and the cross rope in the embodiment of the present invention has eight ropes called eight ropes M. Strands A, A ′, B, B ′, C, C ′, D, and D ′.

  Eight rope M has two strands of left-handed strands, each of which has two strands left-twisted, and two pairs of right-handed strands, each of which has two strands twisted right-hand, and alternates these strands. It is a combination.

  Thus, the cross rope is made by twisting a total of 4 strands of 2 strands of the same twist direction, a total of 8 strands S of 4 right twist strands and 4 left twist strands, Therefore, the cross rope is connected as a pair of two strands in the same twist direction, passed through the other strand in the same twist direction, and wound from the second time 2 to 4 times by the insertion method, and finally the strand 1 Pass through each book and tie the ends with a string to prevent loosening.

  Next, a procedure for contacting the eight rope using the eight rope M by the eye splice method will be described.

(A) Creation of processing margin First, the eight ropes M are loosened for every eight strands S, and a processing margin is formed as shown in FIG.
The machining margin needs to have a length necessary for contacting the eight ropes M by the eye splice method.
Usually, the length of the processing margin is 12 to 15 times the diameter of the strand.

(B) Entrance preparation (split)
After forming the margin, prepare for entry.
The entry means that the strand set is first inserted into the eye size portion of the eight rope body m when the eight rope M is contacted by the eye splice method.
That is, another strand set is inserted between the strand set, and in preparation for opening, each strand is separated one by one and temporarily fixed with the tape 48.
Then, the end of the eight rope M is divided into four strand sets A, A ′, B, B ′, C, C ′, D, D ′.

(C) Entering the mouth When preparations for entering the mouth are completed, enter the next time.
First, the size of the eye P is determined as shown in FIG. Then, the four strand sets A and A ′ prepared for entrance are inserted into the size portion of the eye P in the eight rope main body m.
That is, when inserting the right twist strands A and A ′, as shown in FIG. 3, a hole is made with a spiky 22 in one set of right twist strands of the cross rope.

  Next, the strands of A and A 'are arranged in parallel in the holes opened in FIG.

  Next, as shown in FIG. 5, when inserting a strand set of left-handed strands B and B ′, when one of the left-handed strands adjacent to the strand that has passed through the A and A ′ strand pairs is A and A ′. Open a spiky hole in the same way as above and wind it around.

  Next, as shown in FIG. 6, the strands of the right twist A and A ′ and the left twist B and B ′ are finished, and then the eye is passed through and adjacent to the place where the strands of A and A ′ are passed. The left twisted strand set is made with a spiky hole, and the C, C ′ strand set is inserted here.

  Next, as shown in FIG. 7, when inserting a strand set of right-handed twists D and D ′, a hole is created by spiking the left-hand twisted strand adjacent to the place where the C and C ′ strand pairs are passed through to form a strand pair. Pass them in parallel while winding them.

  In this way, the first splice for inserting each strand set of A, A ′, B, B ′, C, C ′, D, and D ′ into the size of the eye P of the eight rope body m is performed. Complete.

  Next, the splice from the second time is applied to the strands running in the same direction as the strands A, A ′, B, B ′, C, C ′, D, D ′ passed through the first time. , D 'is passed through the entire strand set while being always wound by the winding method.

  This splice is performed about 2 to 4 times. Usually, it may be 2 times, but in the case of a slippery rope, it is better to splice 3 to 4 times in order to maintain a secure tightening state.

  In the case of the D and D 'strand pairs, the splicing process will be described. As shown in FIG. 8, a hole is spiked in the strand next to the strand of the rope passed at the first splicing.

  Next, as shown in FIG. 9, the D and D ′ strand pairs are passed through the holes formed in FIG. 8 while being wound.

Next, as shown in FIG. 10, the D, D ′ strand pairs are not passed through to the end, but are passed alternately in the order of A, A ′ → B, B ′ → C, C ′ → D, D ′ strand pairs.
That is, the tension of each strand set is made constant by aligning the appearance while maintaining the overall balance.
Thus, when the splicing of the last D and D ′ strand set by the winding method is completed, the shape of the splice part is substantially rectangular.

  When performing the final splicing as shown in FIG. 11, first divide each pair of strands one by one, and divide each pair of ropes in the same way, and insert them one by one with a spike. Make a hole.

  Next, as shown in FIG. 12, D is passed through a strand having a hole close to D in one of the strand pairs of D and D '.

  As shown in FIG. 13, when inserting the remaining D ′ strand, the remaining one of the rope strands is spiked and the D ′ strand is inserted into the hole to complete the splicing.

In the embodiment of the present invention, the above cross rope can be easily and reliably connected using a mechanical device.
14 to 35 show the device of the present invention.

  As shown in FIG. 14, reference numeral 1 denotes an eye splicing device, which performs eye splicing on an eight rope and forms a loop-shaped ring at one end of the eight rope.

  The eye splicing device 1 is provided with a donut-shaped turntable 3 in the center of a rectangular machine casing 2, and upper and lower rope grips 4 and 5 are disposed at a certain distance above and below the upper and lower rope grips. A spiky support portion 6 (see FIG. 16) is erected on the turntable 3 in the lateral direction of the portions 4 and 5 and is positioned so as to face the spiky support portion 6 with the upper and lower rope grip portions 4 and 5 as the center. The strand tension portion 7 (see FIG. 16) is erected on the turntable 3. Above the upper rope grip portion 4, a rope guide portion 8 is provided for vertically hanging the eight rope M and guiding it to the center holes of the upper and lower rope grip portions 4, 5.

  As shown in FIGS. 16 and 17, the donut-shaped turntable 3 has a spiky support portion 6 and a strand tension portion 7 that rotate around an eight rope M suspended and fixed to the upper and lower rope grip portions 4 and 5. Thus, the spiky 22 functions to displace the insertion direction.

  That is, the turntable 3 in which the spiky support portion 6 and the strand tension portion 7 are erected and fixed to the peripheral portion includes a pinion shaft 10 provided on an output shaft 9 of a motor (not shown) and an annular rack 11 meshed with the pinion shaft 10. The annular rack 11 is formed on the inner peripheral surface of the donut-shaped turntable 3.

  As shown in FIGS. 14 and 16, reference numeral 12 denotes a support case that supports the turntable 3 that is rotatable via a bearing 12 '.

  As shown in FIG. 17, the upper and lower rope grip portions 4, 5 are provided in the machine frame 2 vertically above the central hole 3 ′ of the donut-shaped turntable 3 via stays 13, 18. A ring shape that can be gripped by inserting the rope M is formed, and a grip piece 15 is slidable toward the center and grips the eight rope M on the inner surface 14 (see FIG. 15) of the ring shape. It is configured to be able to.

  As a sliding mechanism toward the center of the grip piece 15, a narrowing structure such as a camera shutter, a cam mechanism provided at the base end portion of the grip piece 15, or the like can be used. Is provided with an operating mechanism constituting the grip piece 15.

  As shown in FIGS. 14 and 17, the lower rope grip portion 5 is supported by a grip portion lifting mechanism 17 provided on the machine frame 2 via a stay 18, and is located directly below the upper rope grip portion 4. It has a ring shape similar to that of the upper rope grip portion 5 and is structured such that the eight rope M can be inserted and gripped in the ring center hole.

  The grip part raising / lowering mechanism 17 includes a female screw body (not shown) in which the base end portion of the stay 18 is continuously provided, and a male screw body (not shown) that can be screwed into the female screw body and rotated from the outside. By rotating the male screw body, the stay 18 is moved up and down via the female screw body, and the vertical rope grip portion 5 is moved up and down.

  Further, the ring inner surface 19 of the ring-shaped lower rope grip portion 5 is configured such that a grip piece 20 (see FIG. 15) can slide toward the center and can grip the eight rope M. Yes.

  The sliding structure toward the center of the grip piece 20 has the same structure as that of the upper rope grip portion 4, and the operation mechanism thereof is also the same.

  Therefore, the eight rope M inserted through the center of the ring of the upper rope grip portion 4 and gripped by the grip piece 15 is inserted into the hole in the center of the ring of the lower rope grip portion 5 and gripped by the grip piece 15. Since the lower rope grip portion 5 is moved upward by the grip portion lifting mechanism 17 as it is, the gripped eight rope M is in a relaxed state between the upper and lower rope grip portions 4, 5, and the knot is loosened and knitted. A gap is formed between the strands 5.

Furthermore, the upper and lower rope grip portions 4 and 5 are each configured to rotate in the reverse direction.
That is, as shown in FIG. 14, the donut-shaped upper and lower rope grip portions 4, 5 are rotatably attached to the stays 13, 18. Rack surfaces 4-1 and 5-1 are formed, and the pinions 4-2 and 5-2 are meshed with the rack surfaces 4-1 and 5-1, respectively. Are rotated by power such as a motor or manually, the upper and lower rope grip portions 4 and 5 rotate in opposite directions.

  Accordingly, the strand S gripped between the upper and lower rope grip portions 4 and 5 is coupled with the grip portion lifting mechanism 17 to relax the strands of the strand S as much as possible. It facilitates the insertion of the connected spike 22.

  18, 19, and 20 show other embodiments relating to the upper and lower rope grip portions 4 and 5, the reverse mechanism of the upper and lower rope grip portions 4 and 5, and the turntable 3.

  That is, the upper and lower rope grip portions 4 and 5 are respectively composed of left and right semi-arc shaped grip pieces 50 and 50 ′ pivotally supported at the base ends, and the drive racks with the pivot shafts 51 and 51 ′ as pinions in the pivot portions at the base ends. 52, the right and left semicircular arc-shaped grip pieces 50, 50 'are closed and releasable so that the eight ropes can be gripped and released.

  In addition, the upper rope grip portion 4 can be rotated from the center of the left and right semicircular arc-shaped grip pieces 50, 50 ′ so that the upper rope grip portion 4 can be rotated from the center of the grip pieces 50, 50 ′ to the rear of the pivot portion at the base end An arc-shaped reversing rack 53 and a reversing pinion 54 are disposed at the position, and the strand S of the eight rope M gripped by the upper rope grip 4 rotating from the center of the grip piece by driving the pinion 54. Is twisted (see FIG. 21).

  This is because the strand S held between the upper and lower grip portions 4 and 5 is coupled with the grip portion lifting mechanism 17 to relax the strand of the strand S as much as possible, and the spiky 22 (strand described later) It has a function of facilitating insertion of spiky 22) connecting S.

  In FIG. 18, reference numeral 55 denotes a fusing device for fusing the strand S disposed on the side of the upper rope grip portion 4, and is attached to the machine frame 2 via a telescopic arm 56.

  The turntable 3 is formed in a substantially horseshoe shape by cutting out a part of the donut shape, and the rotation mechanism thereof is the same as that of the donut-shaped turntable 3 described above.

In the figure, reference numeral 3-1 denotes a partially cutout portion in the turntable 3 having a substantially horseshoe shape.
In this way, by forming a horseshoe shape with a notch part, the eye rope M released from the upper and lower grip parts 4 and 5 is partially notched after the eye splicing work is completed between the upper and lower grip parts 4 and 5. The removal of the eight rope M from the eye splice device 1 can be facilitated by taking it out from the section 3-1.

  As shown in FIG. 22, the spiky support portion 6 has a support column 21 that is rotatably provided on the periphery of the donut-shaped turntable 3, and is pivotally connected to the upper portion of the support column 21 so as to be tiltable. A substantially cylindrical spiky holding portion 23 to be held, a guide slit 25 formed in the substantially cylindrical peripheral side surface of the spiky holding portion 23 along the longitudinal direction, and a spiky handle 26 protruding from the peripheral surface of the spiky 22. Thus, the spiking handle 26 has a guide slit 25 formed in the spiking holding portion 23 that can freely be stranded.

  As shown in FIGS. 23 (A) and 23 (B), the spiky 22 is composed of a cap 27 having a sharp tip and a spiking main body 28 connected to the rear end of the cap 27. The opening is formed in a hollow cylindrical shape, and a pair of two strands S are inserted into the inside thereof through a rear end opening so that the end of the strand is fixed to the tip of the spiking main body 28.

  As a structure for fixing a pair of two strands S to the tip of the spiking main body 28 as described above, the following three modifications can be considered.

[First Modification]
As shown in FIG. 24 to FIG. 26, the free end of each pair of two strands S is covered with a cylindrical strand cap 30 having a bottom with a tip, and the cap 30 and the end portion of the strand S are fixed with a screw 31. Then, the strand caps 30 and 30 ′ covering the free ends of the two pairs of strands S are inserted into the spiking body 28 and fixed in the vicinity of the base end portion of the spiking cap 27.

  The spiky main body 28 has a flat oval cross section and can be opened and closed in half. A partition wall 32 is formed near the tip of the spiky main body 28.

  Therefore, the strand caps 30 and 30 ′ are engaged with the partition wall 32 when the pair of strand caps 30 and 30 ′ are stored in the spiking main body 28 divided in advance and closed. The spiky main body 28 is divided into two parts by closing the lid, and two sets of strands S are fixed so as not to be removed from the spiky main body 28 via the strand caps 30, 30 'and the partition wall 32. .

[Second Modification]
In the first modified example, the strand caps 30 and 30 ′ are encased in the free ends of the two strands S, and the screws for fixing the free ends of the strands S to the strand caps 30 and 30 ′. In the second modification, the free ends of the strands S are inserted into the strand caps 30 and 30 'as shown in FIG. In order to fix the strand caps 30 and 30 ′ integrally, a long common screw 33 is inserted and screwed into the caps 30 and 30 ′ integrally.

  By doing in this way, it becomes difficult to unravel the strand S rather than wrapping the strand caps 30 and 30 'alone at the free ends of each strand as in the first modified example, and it becomes easier to perform the splicing work in the subsequent process. .

[Third Modification]
As shown in FIGS. 28 to 30, the free ends of the two strands S are bundled together and inserted into a cylindrical strand body 34 that can be divided into two, and the strand 35 is screwed into the screw 35. Are inserted and screwed in and fixed together.

  The cylindrical strand main body 34 that can be divided into two parts is divided into two vertically by using a flexible material such as a resin as shown in FIG. Both side edges of 34 ″ have a fitting shape.

  Since it can be deformed into an integral cylindrical shape and a half-circular arc shape, the free end of each strand S is sandwiched between the half-arc-shaped upper and lower strand bodies 34 ', 34' '.
