Description

Steel strand guide for a manufacturing machne of coating tension member for ground anchor and apparatus for inserting and guiding steel strand using the steel strand guide}

The present invention relates to a strand conductor guide for easily fitting and disassembling the tip of a strand strand to a rear end of a tube, and a strand conductor insertion guide device for a coated tensile material maker of a ground anchor equipped with the strand strand guide.

The cladding material for ground anchors is a strand wire inserted into a hard tube.

Conventional coating liner manufacturers do not have a strand insertion guide device, the operator waits at the position where the strand is inserted, while holding the rear end of the tube in one hand and holding the end of the strand in the other hand to match the rear end of the tube It has been proceeded by hand to insert the operation.

If the diameter of the tube is larger than the thickness of the strand, it can be easily fitted by hand. However, if the diameter of the tube is small enough to match the thickness of the strand, it is not suitable to fit the strand.

Since the work of fitting the strand into the rear end of the tube depends on manual labor, the production of cladding per hour is low, and there are safety issues such as injury to the fingertips or injury to the back of the hand or palm at the end of the strand of the sharp strand.

On the other hand, some of the coating anchor material manufacturing machine for ground anchors is equipped with the tube-strand aiming apparatus (B of FIG. 3) proposed by the person. In the tube-strand collimator A, a rail 2 placed on the base 1 in the horizontal direction is provided with a feed table 4 which can be moved from side to side by the cylinder 3, and the feed table 4 is provided. ), The strand guide (5) and at least one pair of tube guides (6) are arranged in a row, and when the tube is supplied, it moves in front of the tube guide of the strand insertion guide device, and the tube guide is 1 pitch when the strand is supplied. Step back and the strand guide will move in place.

In order to increase the productivity of the cladding material by using the tube-strand aiming device, a strand insertion guide device suitable for that, for example, a strand insertion guide that can accurately and quickly enter the end of the strand into the rear end of the tube regardless of whether the tube is large or small. A device is needed.

SUMMARY OF THE INVENTION An object of the present invention is to provide a strand guide for a cladding fabricator of a ground anchor, which can accurately and quickly fit the tip of a strand to a rear end of a tube.

It is another object of the present invention to provide a strand wire insertion guide device for a coated tensile material manufacturing machine of a ground anchor which can increase the productivity of the coated tensile material by using the stranded wire guide.

In order to achieve the above-described first object, there is provided a strand guide guide formed with a tube hole in the center of the back of the strand wire hole and the rear end of the tube can be barely fitted. When the strand is inserted into the strand line while the rear end of the tube is inserted into the tube hole of the strand guide, the tip of the strand is automatically centered at the rear end of the tube, thereby making it easier to insert the strand later.

The second problem is that the tube is supplied by installing the tube guide and the strand strand guide together so as to move one pitch in the longitudinal direction or transverse direction with respect to the feed direction of the tube and the strand strand by a driving means for performing one pitch stroke. When the tube guide is in position, the tube is fed and the trailing edge is cut, and when the strand is supplied, the strand guide moves to the position where the tube guide is withdrawn by one pitch. The bite line is inserted into the rear end of the tube while the rear end of the tube is pulled out of the tube guide and then retracted so that the rear end of the tube is inserted into the tube hole of the stranded strand guide. As soon as the two edges were advanced with the cladding material cut off at the rear edge, By switching off the rim can be achieved with a coating prepared appointed strand tension member insertion of the ground anchor is configured to allow release of tension member covered with the guide apparatus.

In FIG. 1, the strand guide 10 is divided into a first half and a second half for convenience. Following the nucleus-shaped guide part 11 of the front end, the strand wire hole 12 is located, and the latter part is formed in the order of the tube hole 13 and the nipple head 14 in order. The front noodle section 11 is a part to induce the leading end of the strand to enter the strand 12, and the rear nipple section 14 to induce the rear end of the tube to enter the tube hole 13 to be inserted correctly. Part.

The strand wire 12 has a diameter that the bare strand for bare cladding can barely pass through, and the tube hole 13 has a bore that can barely fit a tube having a larger outer diameter than the strand. The strand wire 12 and the tube hole 13 are located on the concentric line.

In FIG. 2, the inner end surface of the rear end of the tube T inserted in the tube hole 13 coincides with or slightly larger than the diameter of the strand wire 12. In this way, when the end of the strand (SW) is pushed into the nipple head 11 in a state in which the rear end of the tube T is inserted into the tube hole 13, the tip is guided to the guide part 11 to naturally give the strand wire 12. Will be entered. If pushed further in the twisted line (SW) to enter the rear end of the tube (T), the center of the tip of the strand (SW) is naturally matched with the center of the rear end of the tube (T). Therefore, the tip of the stranded wire SW is smoothly entered without being caught by the rear end of the tube T.

The configuration conditions of the strand wire 12 and the tube hole 13 is to insert the strand wire (SW) quickly to obtain a coating tensile material having a small dimension difference, especially between the diameter of the strand wire (SW) and the tube diameter of the tube (T) Very useful.

As the tube hole 13 is formed in the concentric line, the rear end of the tube is barely inserted behind the strand wire 12 of the size of the strand wire barely enough to pass through, so that the strand wire guide is fixed and the tip of the strand wire is manually aligned with the end of the tube. Regardless of whether the wire is inserted or automated by the wire insertion device (described later) or inserted into the wire, the wire can be easily and quickly inserted into the tube, thereby improving the productivity of the coated tensile material.

 3 to 5, the strand insertion guide device (D) is composed of a tube guide 20, guide moving means 30, tube vise 40, in addition to the strand guide (10) described above.

The tube guide 20 guides the supplied tube to pass through correctly. In the first half, a nipple head 21 is formed to guide the leading end of the entering tube to enter the tube hole 22 correctly. A tube hole 22 having a pore size that can barely pass is formed. The nipple head 21 and the tube hole 22 are located on the concentric line.

The strand wire guide 10 and the tube guide 20 are made of a material having the same height or width on the premise of moving one pitch within a predetermined range. This is a necessary condition for inserting the strand into the rear end of the pre-supplied tube. For example, in the case of selecting a material having the same height, the strand wire guide 10 and the tube guide 20 are mounted on the left and right movable means in a row, and the strand wire guide 10 and the tube guide 20 are simultaneously moved to one side by one pitch. In the case of the same width, the strand conductor guide 10 and the tube guide 20 are mounted side by side in a lifting type moving means so that the strand strand guide 10 and the tube guide ( 20) by moving 1 pitch up and down to change the position at the same time.

Here, the pitch P means the distance between the center of the tube hole 22 of the tube guide 20 in the center of the strand wire hole 11 of the strand wire guide 10.

In the drawing, the strand guide 10 and the tube guide 20 are shown in a separate material, and the plurality of strand wire 12 and the tube hole 22 are perforated, welded up and down, and welded together. The internal structure of the tube 10 and the tube guide 20 may be formed side by side, and the strand wire 12 and the tube 22 may be replaced with a singular one.

    Guide movement means 30 by changing the position of the strand guide 10 and the tube guide 20, it can assume the lifting and lateral movement. The figure corresponds to the former case. That is, it consists of the slider 31 guided by the rail 51 provided in the front-end | tip of the base 50, and the slider drive means 32. As shown in FIG. The slider drive means 32 is a cylinder or solenoid. The slider 31 is for 1 pitch up and 1 pitch down (return) of the strand guide 10 and the tube guide 20. In principle, one pitch of lifting and lowering of the slider 31 adjusts the stroke of the slider driving means 32 accordingly. Alternatively, a drill hole 33 having a length corresponding to one pitch lift of the strand guide 10 and the tube guide 20 is drilled in the slider 31, and the movement of the active hole 33 in the base 50 is performed. It is also conceivable to install a pin 52 to induce.

The tube guide 20 is shown mounted on the strand strand guide 10. This is because the strand guide 10 is moved to the seat of the tube guide 20 which is moved up by 1 pitch after the tube guide 20 is supplied from the tube and is fixed. Then, through the rear end of the tube inserted into the tube hole 13. It is suitable for the way the strand is inserted. The strand wire guide 10 may be mounted on the tube guide 20. In this case, the tube is supplied in the state in which the tube guide 20 is in position, and when the pitch is lowered by one pitch, the strand line guide 10 is moved to the position so that the strand is inserted. This change is also possible through the stroke adjustment of the slider drive means 32.

6 shows the strand guide 10 and the tube guide 20 arranged side by side, and the slider 31 and the slider driving means 32 are also installed in the arrangement direction of the strand guide 10 and the tube guide 20. It shows the case where the position can be changed by moving one pitch in the direction perpendicular to the feeding direction of the strand and the tube. The tube vise 40 passes through the tube guide 20 by a predetermined length, and then advances by biting the tube cut by the cutter C. Then, the tube guide 20 moves one pitch, and the strand wire guide ( 10) retreat in a state where it is moved to the back, and the rear end of the tube is inserted into the tube hole (13) to support the strand to be inserted correctly to the rear end of the tube.

In FIG. 7, the tube vise 40 has a spindle 41 for pressing and holding on the tube and a spindle driving means 42 for raising and lowering the spindle 41.

       3 to 5, the tube vice 40 is provided on the base 50 along the direction in which the tube and the strand travel in the rear of the strand guide 10 and the tube guide 20. Install to ride around.

The tube to be supplied passes under the spindle 41 lifted by the spindle driving means 42, and when the tube stops after being fed by the design length, the spindle 41 descends to bite the rear end of the tube. The spindle 41 is inserted at the rear end of the supplied tube and the boundary line is cut by the cutter C, and then the tube vice 40 is advanced by two steps to reach the point where the coated tensile material can be taken out. Let go of the tube you were biting.

The tube vise 40 further repeats the daily advance and the daily retreat and the two-beam forward and return operations by the vise moving means 43 provided between one point of the bottom face and one trailing point of the base 50 described later.

Reference numeral A is a tube feeder, B is a collimator for positioning the tube or strand of the selected line to the tube guide 20 or the strand guide 10 on the strand insertion guide device (D), and (44) As a guide rail supporting the rear end of the tube, the guide rail is attached to the rear end of the tube vise 40. Further, 54 supports the guide rail 44 moving along the tube vise 40 on the base 50, and guides the tip of the tube to be correctly entered the tip of the cladding vise when installing the cladding vise. Induction guide is indicated.

The order of manufacturing the coated tensile material by pre-feeding the tube and post-feeding the stranded wire is as follows. As shown in FIG. 4, the tube guide 20 is positioned in front of the tube vice 40, which is normally in the standby position, and the strand guide 10 stands by one pitch away from the tube guide 20. When the tube T having a length corresponding to the design length is supplied to the tube guide 20 and stopped, the cutter C is lowered and cut, and the cutter C is returned. The surface cut | disconnected by the cutter C is a trailing boundary line of the tube T supplied.

In FIG. 8, the rear end of the cut tube T is snapped into the tube vice 40 and further advanced so that the rear end of the tube T exits the tube guide 20.

In FIG. 9, the tube guide 20 and the strand conductor guide 10 are raised by one pitch with the slide driving means 32 so that the strand conductor guide 10 is positioned at the position where the tube guide 20 was located.

The tube vise 40 is retracted by the vise moving means 43 and the rear end of the tube T is inserted into the tube hole 13 of the strand guide 10. After that supply the strand (SW). The tip of the strand SW enters the rear end of the tube T through the strand 12. After the strand SW is inserted as much as the design length, the cutter C is lowered and cut. At this time, it becomes the coated tensile material.

In FIG. 10, the tube vise 40 is advanced by two beams to move the coated tensile material to the unloading standby position so that the rear end of the strand wire SW completely exits to the rear end of the strand wire guide 10. In FIG.

Application of the strand wire insert guide device (B) to the coated anchor material for ground anchors, even if the tolerance between the tube and the strand is small, since the tip of the strand is inserted very smoothly and quickly without catching the rear end of the tube, the productivity of the coated tensile material is improved. It can be dramatically increased and is safer than inserting the strand into the tube by hand.

The coated tensile material vise 60 may be added to the strand insertion guide device B. FIG. The cladding vise 60 picks up the cladding material just before the vise bite is released from the tube vise 40 so that the cladding material does not come off when the tube vise 40 releases the bite to the cladding material and returns. , By operating the spindle 61 as the spindle drive means 62 is configured to bite or loosen the coated tensile material.

The coated tensile material vice 60 is provided farther from the distance when the tube vise 20 moves forward by two beams on the base 50 to avoid collisions even when the tube vise 40 moves forward by two beams.

As described above, the strand guide of the present invention has a tube hole in which the rear end of the tube is barely inserted at the rear of the strand wire, so whether the strand is inserted into the tube by using an automated device or by inserting the strand into the tube manually, It is easy, fast and accurate, and can greatly improve the productivity of the coated sealant.

In addition, the guiding wire insertion guide device for arranging the tube guide and the guiding wire guide side by side and correctly entering the leading end of the guiding wire into the rear end of the tube pre-fed by the driving means by the driving means is made of coated tensile material. It is possible to dramatically increase the productivity of the coated seal with a small tolerance.
