BACKGROUND OF THE INVENTION
  The present invention provides a pulling wire used for pulling a self-supporting cable having a cross-section dull sheath that covers a support wire (suspension wire or messenger wire) and a cable core in a lump and has an extra length provided to the cable core. It is about improvement of a take-off machine.
[0002]
[Prior art]
  The self-supporting cable is extended when the cable is laid, tightly connected, or subjected to wind pressure, etc., and the cable core is extended accordingly. There is a risk that the loss increases and the cable core breaks. For this reason, a self-supporting cable with a surplus length along the support line while giving a surplus length to the cable core is used.
[0003]
  As shown in FIGS. 1 (A) and 1 (B), the extra length self-supporting cable 1 includes a support wire 2 and a cable of a cross-section dull type sheath 4 that collectively covers the support wire 2 and the cable core 3. The cable core 3 is formed to meander in the direction parallel to the longitudinal direction of the support line 2 while forming a slit 5 with a gap in the sheath neck portion 4a between the core 3 and the core 3. The slit 5 is provided between the support wire 2 and the cable core 3 when an extra length is given to the cable core 3 by the contact surface 20a (see FIG. 4) of the sheave 20 of the cable manufacturing apparatus described later with reference to FIG. The sheath neck portion 4a has a function of allowing the cable core 3 to meander.
[0004]
  An apparatus for manufacturing this type of extra-length self-supporting cable is described in, for example, Japanese Patent Application Laid-Open Nos. 8-75969 and 8-86944. The manufacturing apparatus 10 of the prior art will be described with the aid of the manufacturing apparatus 10 for a self-supporting cable with extra length shown in FIG. 2 to which the present invention is applied. Means 12, cable core unwinding means 14 for unwinding the cable core 3, and the support wire 2 and the cable core 3 are collectively covered to form the cable 1 having the cross-shaped sheath 4 but the support wire 2 and the cable core 3 The sheath forming means 18 composed of an extruder 16 that intermittently forms the slit 5 in the sheath neck portion 4a between the support wire 2 and the cable core 3 covered with the cross section-shaped sheath 4 are wound around the sheave 20. The extra length giving cooling hand which cools the cable 1 by the cooling water tank 22 in which the sheave 20 is immersed while giving extra length to the cable core 3 while feeding at different peripheral speeds. It is equipped with a 24. The extra-length self-supporting cable 1 manufactured in this way is wound around the winding drum 122 on the winding machine 120 while being pulled by the winding machine 30.
[0005]
  As shown in FIGS. 3 (A) and 3 (B), the slit 5 of the sheath neck portion 4a is formed in the mold recess of the die 26 of the extruder 16 (the mold recess having a bowl shape corresponding to the shape of the sheath 4). The movable pin 28 is intermittently inserted into and removed from a through hole 26b penetrating across the neck portion of 26a. That is, when the movable pin 28 is inserted so as to cross the mold recess 26a, a slit 5 is formed in the sheath neck portion 4a between the support wire 2 and the cable core 3, and when the movable pin 28 is removed from the base 26, it is supported. The sheath neck portion 4a between the wire 2 and the cable core 3 is continuous (see FIG. 1A).
[0006]
  As shown in FIG. 4, the sheave 20 has a contact surface 20 a with which the cable 1 comes into contact, and the support wire 2 and the cable core 3 are fed while being wound at different peripheral speeds. As shown in FIG. 4, on the contact surface 20 a with which the sheave 20 contacts, the axial center of the cable core 3 is located radially outside the axial center of the support wire 2. The cable core 3 is fed in excess of the support wire 2 than the peripheral speed of the support wire 2. Therefore, as shown in FIG. The cable 1 is manufactured in which the cable core 3 meanders at the slit 5 and is cured.
[0007]
  As shown in FIG. 17, the take-up machine 30 includes upper and lower endless take-up belts 34 and 34 'between which the cable 1 is sandwiched, and holding surfaces 34a and 34'a of the take-up belts 34 and 34'. The crimping rolls 62 and 62 ′ are opposed to each other so as to be crimped to the cable 1, and the clamping belts 34a and 34′a are crimped to the cable 1 by these crimping rolls 62 and 62 ′, and the take-up belt 34, 34 'drive direction (Of FIG.The cable 1 is pulled in the left direction).
[0008]
  However, the window-equipped self-supporting cable 1 with a surplus length enters the take-up machine 30 in a meandering manner due to the surplus length of the cable core 3, so that the cable core 3 is placed between the upper and lower opposing crimping rolls 62, 62 '. Since the meandering portion can be used or crushed, the cable core 3 may be deformed or damaged to deteriorate the characteristics of the cable, and in the worst case, the cable core 3 may be disconnected.
[0009]

In the example shown, the take-up machine 30 has three pairs of crimp roll assemblies 36, 36 ', but the number of crimp roll assemblies may be one, two, four or more.
[0023]
  The take-up belts 34, 34 ′ are stretched between drive wheels 38, 38 ′ rotatably supported on the machine frame 32 and driven wheels 40, 40 ′. It is connected to belt driving means 42 (see FIG. 6). As shown in FIG. 6, the belt drive means 42 is connected to a drive motor 44, a speed reducer 48 connected to an output shaft 44 a of the drive motor 44 via a belt / pulley mechanism 46, and the speed reducer 48. And another belt / pulley mechanism 50. One pulley of the belt / pulley mechanism 50 is connected to the drive wheel 38 via the transmission gear 52, and the other pulley of the belt / pulley mechanism 50 is directly connected to the drive wheel 38 '. Accordingly, the take-up belts 34 and 34 'are driven in the same direction at a constant speed by the belt driving means 42.
[0024]
  Returning to FIG. 5 again, the tie toners 54 and 54 ′ are attached to the machine frame 32, and these tie toners 54 and 54 ′ adjust the tension of the take-up belts 34 and 34 ′. The tie toners 54 and 54 'are attached to the air cylinders 58 and 58' pivotally supported by the machine frame 32 via brackets 56 and 56 ', and the pistons of these air cylinders 58 and 58'. The support shafts 40 a and 40 ′ of the wheels 40 and 40 ′ are composed of levers 60 and 60 ′ that advance and retract in the front-rear direction of the take-up machine 30.
[0025]
  As shown in FIGS. 7 and 8, each pair of the crimping roll assemblies 36, 36 ′ is a roller that holds a plurality of the crimping rolls 62, 62 ′ at intervals in the transport direction (take-off direction) of the cable 1. Holding frames 64, 64 'and arms 70, 70' attached to these roller holding frames 64, 64 'and pivotally supported by brackets 66, 66' on the machine frame 32 by pins 68, 68 '. It consists of. Accordingly, the roller holding frames 64, 64 ′ are moved up and down in directions opposite to the arms 70, 70 ′ pivoting around the pins 68, 68 ′, and the pressure rolls 62, 62 'is closed towards the take-up belts 34, 34' or opened away from these take-up belts 34, 34 '.NeedTo work.
[0026]
  As shown in FIGS. 7 and 8, the pressure roll opening / closing means 72 includes a link 74 that connects the arms 70 and 70 ', and a roller opening and closing drive source 76 that moves the arms 70 and 70' up and down. One end 74a of the link 74 is provided integrally with the arm 70 via a pin 68 so as to swing integrally with the arm 70, and extends to the opposite side of the arm 70 with respect to the pin 68 (not shown in FIG. 8). (Not shown) is pivotally connected via a pin 78 and the opposite end 74b of the link 74 is connected to the arm 70 '.Pin 78 'It is connected pivotally through.
[0027]
  Accordingly, when the upper arm 70 is pivoted clockwise around the pin 68 as observed in FIG. 7, the pressure-bonding roll 62 rises together with the roller holding frame 64, but is integrated with the arm 70 via the pin 68. The auxiliary arm 70A is also pivoted clockwise by the clockwise pivoting of the arm 70, so that the lower arm 70 'is pivoted counterclockwise about the pin 68' via the link 74, The pressure-bonding roll 62 ′ is lowered together with the roller holding frame 64 ′, and the upper and lower pressure-bonding rolls 62, 62 ′ are opened to release the take-up belts 34, 34 ′ from the cable 1. On the other hand, when the upper arm 70 and the auxiliary arm 70A pivot in the counterclockwise direction, the pressure-bonding roll 62 is lowered together with the roller holding frame 64, but the lower arm 70 ′ is moved by the counterclockwise pivoting of the arm 70. It pivots clockwise around the pin 68 ′ via the link 74, the pressure roller 62 ′ rises together with the roller holding frame 64 ′, the upper and lower pressure rollers 62, 62 ′ are closed, and the take-up belts 34, 34 ′. Is crimped so as to sandwich the cable 1.
[0028]
  The roller opening / closing drive source 76 isFIG.As shown in FIG. 7, the arm 70 'is pivotally connected to a support member 82 on which the fluid cylinder 80 is supported via a pin 84 (see FIG. 7). The arm 70 is pivotally connected to a linkage member 86 that engages with an upper end 80 b of the piston 80 a of the fluid cylinder 80 via a pin 88.
[0029]
  Therefore, when the piston 80a of the fluid cylinder 80 is contracted, the connecting member 86 associated with the piston 80a is lowered by its own weight, so that the pressure-bonding rolls 62 and 62 'are closed, and conversely, when the piston 80a of the fluid cylinder 80 is extended. Since the piston 80a pushes up the connecting member 86, the pressure-bonding rolls 62 and 62 'are opened.
[0030]
  As shown in FIGS. 5 and 7, the take-up machine 30 according to the present invention includes a crimping roll 62 of a crimping roll assembly 36 on one side and a crimping roll assembly on the other side of the cable 1 to be taken up. The crimping roll 62 'of the three-dimensional 36' is not opposed to each other, and is arranged so as to be displaced from each other in the transport direction (take-off direction) of the cable 1. Therefore, when these crimping roll assemblies 36, 36 'come close to each other, the cable 1 to be taken up is, as shown in FIG. 10, the upper and lower crimping rolls 62 via the take-up belts 34, 34'. , 62 ′, and sequentially with alternating contact.
[0031]
  As shown in FIGS. 8 and 9, the take-up machine 30 of the present invention further includes a crimping roll interval adjusting means 90 that adjusts the interval between the crimping roll 62 on one side and the crimping roll 62 ′ on the other side. ing. This crimping roll interval adjusting means 90 isFIG.As shown in FIG. 2, the first block 92 attached to the roller holding frame 64, the second block 94 attached to the roller holding frame 64 ′, and the first block 92 are engaged with the block 92. The stopper 96 is to be abutted against the stopper surface 92a, and the screw square tube 98 is screwed to the stopper 96 and extends between the blocks 92 and 94. The stopper 96 is coupled to a stopper support rod 100 that extends through the screw tube 98 and is fixed to the second block 94 via a spline 102 that allows linear motion but prevents rotational motion.
[0032]
  Accordingly, when the screw square tube 98 is rotated by engaging a wrench or the like with the square outer surface of the screw square tube 98, the stopper 96 is prevented from rotating by the stopper support rod 100, so that it expands and contracts with respect to the screw square tube 98. Thus, the position of the stopper 96 is adjusted. When the stopper 96 extends with respect to the threaded square tube 98, the distance between the crimping rolls 62 and 62 'when the cable 1 is pulled is increased, and conversely, when the stopper 96 contracts with respect to the threaded square tube 98, the cable 1 The distance between the pressure-bonding rolls 62 and 62 ′ when taking up is reduced.
[0033]
  Next, the operation of the take-up machine 30 of the present invention will be explained. The self-supporting cable 1 with extra length as shown in FIGS. 1 and 2 fed from the manufacturing apparatus 10 shown in FIG. 5, the take-up belts 34, 34 'are maintained at a predetermined tension by the tie toners 54, 54', and the three pairs of pressure roll assemblies 36, 36 are fed. 'Is closed by the pressure roll opening / closing means 72.
[0034]
  As already mentioned, each pair of crimp roll assemblies 36, 36 'includes a crimp roll 62 of the crimp roll assembly 36 on one side of the cable 1 and a crimp roll assembly 36' on the other side. The crimping rolls 62 'are not opposed to each other and are arranged so as to be shifted from each other in the take-off direction of the cable 1, so that the self-supporting cable 1 with extra length is crimped as shown in FIG. For each roll assembly 36, 36 ′, from the right side to the uppermost right crimping roll 62, the lowermost rightmost crimping roll 62 ′, the upper right next crimping roll 62, the lower next pressing roll Immediately contact (engage) with the pressure roll 62 'on the left side. In this case, as shown in FIG.DarumaThe mold section is sandwiched in a laid state, and the extra length of the cable core 3 extends in a wave shape up and down. Accordingly, the extra length of the cable core 3 of the self-supporting cable 1 with extra length can be bent to the opposite side of the crimping roll with which the cable core 3 contacts (see reference numeral 3A in FIG. 10). The cable core 3 is not caught or crushed unlike the case where the rolls 62 and 62 'are opposed to each other. Accordingly, since the cable core 3 is not deformed or damaged by the pressure-bonding rolls 62 and 62 ′, the cable characteristics are not deteriorated and the cable core 3 is not disconnected. Even if the bulge of the cable core 3 due to the extra length is on the side of the crimping roll that is actually in contact, the bulge can escape to the vacant space on the opposite side that does not have the crimping roll. Join, but never get caught or crushed.
[0035]
  A crimping roll 62 of one crimping roll assembly 36 on one side of a pair of crimping roll assemblies 36, 36 'disposed opposite to each other across the cable 1 and a crimping roll 62 of the other crimping roll assembly 36'. 'Is merely displaced in the take-off direction of the cable 1, so that the cable 1 is engaged with the crimping rolls 62, 62 ′ in a wave-like manner while the crimping rolls 62, 62 ′ are mutually engaged. As a result, the cable 1 is surely given a take-up force and can be taken up.
[0036]
  The distance between each pair of crimping roll assemblies 36, 36 'arranged with the cable 1 in between (the spacing between the lowered position of the crimping roll 62 and the raised position of the crimping roll 62') is the self with the extra length to be taken. According to the thickness of the supporting cable 1 (the diameter of the cable core 3), the pressure is adjusted by the crimping roll interval adjusting means 90. If the take-up machine 30 does not have this spacing adjustment function, as shown in FIG. 11, each pair of the crimping roll assemblies 36 and 36 'has a crimping roll 62 and 62' in the closed state. Thus, the self-supporting cable 1 with extra length is taken up while meandering the lower and upper sides of the upper and lower pressure-bonding rolls 62, 62 ', 62, 62'. In such a state, the cable 1 is extremely bent, and particularly when the bulge due to the extra length is on the pressure-bonding roll side, the cable 1 not only escapes to the opposite side of the bulge direction but is actually in contact. Since it is excessively bent to the opposite side including the biting portion of the crimping roll, the cable characteristics are deteriorated, which is not preferable.
[0037]
  In the above-described embodiment, each crimping roll 62, 62 ′ of the pair of crimping roll assemblies 36, 36 ′ arranged with the cable 1 interposed therebetween is shifted in the take-up direction, as shown in FIG. In addition, the plurality of pressure-bonding rolls 62 and 62 ′ may be shifted in the take-up direction.
[0038]
  Another embodiment of the present invention is shown in FIG. 14, in which each pair of crimp roll assemblies 136, 136 ′ has a plurality of crimp roll groups 162A, 162B, and 162 ′ that face each other vertically. A, 162′B, the pair of crimping roll assemblies 136, 136 ′ is configured such that a plurality of these opposing crimping roll groups, for example, the crimping roll groups 162′A, 162B, are alternately arranged in the take-off direction. Used selectively closed to engage the cable 1. In this way, the upper and lower pressure-bonding roll groups 162A and 162'A do not sandwich the cable 1, and the cable core 3 can be pulled while being reliably absorbed. In this embodiment, for example, when a cable that does not include a surplus length is to be taken, the cable 1 is directly connected by the pressing roll groups 162A and 162′A and 162B and 162′B facing each other as shown in FIG. Can be picked up. 14 and 15, the crimping roll group is selected as a crimping position (positions of the crimping rolls 162′A and 162B in FIG. 14) and a non-crimping position (positions of the crimping rolls 162A and 162′B in FIG. 14). The mechanism to do is omitted. 14 and 15, the same reference numerals are given to the same portions as those in the embodiment of FIGS. 7 and 8.
[0039]
  As will be understood from the embodiment of FIG. 14, if the take-up machine 30 is exclusively used for a self-supporting cable with a cross-sectional length, one of the pressure-bonding roll groups 162A and 162′A facing each other in the embodiment of FIG. For example, 162A may be omitted, and the other of the pressure-bonding roll groups 162B and 162′B, for example, 162′B, may be omitted. An embodiment thereof is shown in FIG.
[0040]
  In the above embodiment, the take-up machine 30 of the present invention is provided with a pair of take-up belts 34 and 34 '. However, the present invention is also applicable to a case where a plurality of take-up belts are arranged in tandem. Needless to say, in this case, a crimping roll or a crimping roll assembly to which the principle of the present invention is applied is provided for each pair.
[0041]
  Furthermore, in the illustrated embodiment, the press roll interval adjusting means 90 is composed of a stopper 96 advance / retreat mechanism by screw coupling of the screw square tube 98 and the stopper 96 as shown in FIG. An appropriate mechanism can be used.
[0042]
  In the above-described embodiment, the pair of pressure rolls 62, 62 ′ or the pressure roll assemblies 36, 36 ′ are separated from the take-up belts 34, 34 ′ so as to be separated from the take-up belts 34, 34 ′. Although released, for example, the lower crimp roll 62 'or crimp roll assembly 36' remains engaged with the corresponding take-up belt 34 'so that the upper crimp roll 62 or crimp roll assembly 36 is correspondingly taken up. The belt may be released from the take-up belts 34 and 34 ′ so as to be separated from the belt 34.
[0043]
【The invention's effect】
  According to the present invention, as described above, since one crimping roll and the other crimping roll arranged with the cable sandwiched therebetween are arranged so as not to be opposed to each other, these crimping rolls are cables. Because the cable core of the self-supporting cable with extra length can be deflected into the vacant space on the opposite side of the crimping roll with which this cable core is in contact The cable core will not be gripped or crushed, so the cable core will not be deformed or damaged, so the cable characteristics will not be deteriorated and the cable core will not be broken. .
[0044]
  Further, since the cable to be taken up is engaged in a wave-like manner between the crimping rolls on both sides of the cable, the cable is surely given a take-up force by the mutual action of these crimping rolls. Can be taken over effectively.
[0045]
  Furthermore, if the distance between the crimping rolls on both sides of the cable can be adjusted according to the outer diameter of the cable, excessive wavy deformation will be imparted to the cable, causing curling or damage. Can be effectively prevented.
