Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a technique for trimming and cutting a front and rear end portion of a product wound in a coil shape after rolling in a steel bar wire rolling facility.
[0002]
[Prior art]
  In the steel bar wire rolling equipment, after the wire rod rolling, the wire rod is wound into a coil shape and shipped as a product. At that time, the front and rear end portions of the coil are trimmed and cut over a predetermined length.
  The purpose of this cut is to cut and remove the dimensional tolerance and the standard of mechanical properties, and usually about 1 to 3 turns are cut. When removing the influence (water cooling at the tip) due to water cooling during rolling, 10 or more turns may be cut and removed.
[0003]
  Sample cutting for quality assurance is also performed at the same time. The length of this sample is about 300 mm.
  Conventionally, the trimming cut is usually manually cut in the course of cooling on the hook conveyor after the wire is formed into a coil shape. A hydraulic shear was used for the cutting (see, for example, Japanese Utility Model Publication No. 2-6979).
  In the above-mentioned trimming cut by manual work, the coil on the hook conveyor is still at a high temperature of about 200 to 300 ° C., and when cutting, the crop (end to be cut and removed) is supported by the person, and the person goes offline after cutting. It was a heavy labor to carry the crop.
[0004]
  Therefore, as a cutting device for reducing the trimming work on the hook conveyor, for example, a device described in JP-A-9-29533 has been proposed.
  This conventional apparatus is a device that suspends and holds a wire coil on a C-shaped hook of a hook conveyor of a rod and wire rolling facility, and trims the end of the coil in the held state. Was clamped with a pair of V-shaped metal fittings, and the cut portion was cut with a cutter blade.
[0005]
[Problems to be solved by the invention]
  The conventional one described in Japanese Patent Laid-Open No. 9-29533 has an effect that it is not necessary to support the trimming part manually at the time of cutting, but since there is only one cutting point, the coil main material and Even if the end member (crop material) is cut off, the end member remains on the hook, and therefore, the unloading of the crop after cutting still has to be done manually, and the trimming work can be sufficiently reduced. It was not.
[0006]
  Furthermore, on the open side of the C-shaped hook (the free end side of the hook tip), the crop can be easily removed from the hook even by cutting at one point. On the closed side (the base side of the hook), the crop is To remain on the hook and to remove it from the hook, the crop must be pulled out in the longitudinal direction of the wire, and the operation of removing it from the hook is difficult.
  In addition, sample cutting cannot be performed at the same time, and a sample collection step is required separately.
[0007]
  Accordingly, an object of the present invention is to provide a coil trimming method and apparatus for reducing the work from cutting to carrying out of the crop even on the closed side of the C-shaped hook. Moreover, it aims at performing a sample cut simultaneously.

  FIG. 1 shows a product wound in a coil shape after rolling on a hook conveyor 1 in a steel bar wire rolling facility (hereinafter, the entire product is referred to as “coil 2”, and the coil component is referred to as “wire”). It shows the state of holding and holding.
  The hook conveyor 1 has a C-shaped hook 3, and the C-shaped hook 3 is suspended and held movably by a traveling rail (not shown). The C-shaped hook 3 has a support arm portion 4 that is inserted through the inner diameter of the coil 2 and holds the coil 2. In the present specification, the free end portion side of the support arm portion 4 is referred to as an “open side”, and the base portion side on the opposite side is referred to as a “close side”. The coil 2 is inserted and held in the support arm portion 4 from the open side.
[0016]
  The technique for cutting and removing the open and closed ends of the coil 2 in the state shown in FIG. 1 over a predetermined length (predetermined number of turns) is the coil trimming method and apparatus according to the present invention.
  Hereinafter, it demonstrates along each work process.
  FIG. 2 shows a sorting process, in which an end cutting portion (hereinafter referred to as “trimming portion 5”) and a coil main material 6 to be cut and removed are sorted manually, and a space S is formed between the both. That is, the trimming part 5 is separated from the main material 6 by a predetermined amount, and a space S is provided between both the parts 5 and 6.
[0017]
  Note that the length of the trimming portion 5 is appropriately set according to the purpose of trimming cut.
  3-5 show a grip process. This gripping process is automatically performed by the clamping device 7.
  The clamp device 7 is provided on both the open side and the close side of the hook conveyor 1, and includes a moving device 8 that is movable in the axial direction of the coil 2, and a grip device 9 provided on the moving device 8.
[0018]
  The moving device 8 is movable, positioned and fixed on the laid rail 10.
  The grip device 9 is provided at the tip of an arm 11 protruding to the coil 2 side from the moving device 8, and grips the wire of the trimming portion 5 in the vicinity of the support arm portion 4 of the C-shaped hook 3. It has a pair of upper and lower grippers 12. The upper and lower grippers 12 are formed in a rod shape, are arranged in parallel to each other, and can be opened and closed by a hydraulic device 13. And the front-end | tip part of any one gripper 12 is bent by L shape, and is made into the hook part which hooks a wire. The length of the gripper 12 is such that all of the wire rods of the trimming portion 5 can be gripped simultaneously from the inner surface side and the outer surface side of the coil 2 along the axial direction of the coil 2.
[0019]
  The pair of upper and lower grippers 12 are provided on both sides in the coil circumferential direction via the support arm portion 4.
  In order to grip the wire rod of the trimming portion 5 with the clamp device 7 having the above-described configuration, first, the grip device 9 is brought close to the end portion of the coil 2 from both sides of the coil 2, and between the pair of upper and lower grippers 12, The moving device 8 is advanced and stopped until the wire rod of the trimming unit 5 is positioned. Then, the gripper 12 is closed by the hydraulic device 13 and the wire rods of the trimming portion 5 are all gripped simultaneously.
[0020]
  The grip device 9 is positioned by, for example, automatic positioning by remote operation by counting the number of cuts given in advance from the imaging screen at the end of the coil 2 by the image processing device and controlling the movement of the moving device 8. it can.
  Also, automatic positioning using a limit switch or the like is possible by leaving the space S by manual sorting. Furthermore, it can also be performed by image processing that detects markings made by a person.
  That is, as shown in FIG. 6, in the sorting step, the coil end (trimming portion 5) is manually arranged so as not to overlap, so that the slit light is applied to the wire with a laser to draw the outline of the wire. The coil end (trimming unit 5) is recognized by a so-called light cutting method detected by a CCD camera, a sorting point is obtained from the detected image, and the grip unit 9 is moved to automatically operate the grip unit 9. Positioning is possible.
[0021]
  Then, as shown in FIGS. 7 to 9, after gripping the trimming portion 5, the grip device 9 is moved backward by the moving device 8 to separate the main material 6 from the trimming portion 5.
  This separation is caused by the wire material falling in the next cutting process hitting the main material 6 and scratching it.
This is to prevent it from being attached.
  At this time, if the wire rod is a stiff material such as spring steel, the coil main material 6 tends to be separated, so that when the grip device 9 is pulled in, the distance to the main material 6 is ensured. It is preferable to provide a stopper (not shown) for preventing anti-skid.
[0022]
  10 to 15 show a cutting process, which is performed by the cutting device 14.
  The cutting device 14 is provided on both the open side and the close side of the hook conveyor 1, and includes a moving device 15 that is movable in the axial direction of the coil 2, and a cutter device 16 provided in the moving device 15.
  The moving device 15 can be moved, positioned, and fixed on a rail 17 installed.
  The cutter device 16 includes a hydraulic device 18 and a pair of upper and lower cutters 19 that can be opened and closed by the hydraulic device 18.
[0023]
  The cutters 19 are arranged so as to be positioned on both sides of the grip device 9 in the circumferential direction of the coil. And this cutter 19 can cut | disconnect all the wire materials of the trimming part 5 gripped by the said grip apparatus 9. FIG.
  In order to cut the wire rod of the trimming unit 5 by the cutting device 14, first, the cutter device 16 that has been retracted is advanced by the moving device 15 with respect to the trimming unit 5 after the gripping process, and the cutter 19 is moved. The wire rod of the trimming unit 5 is positioned between the upper and lower cutters 19 and positioned on both outer sides of the pair of left and right grippers 12.
[0024]
  Then, the cutter 19 is closed by the hydraulic device 18 to cut all the wire rods of the trimming portion 5.
  By this cutting, the non-grip portion of the trimming portion 5 falls downward due to its own weight. The crop processing conveyor 20 is disposed at the dropping position, and the trimming unit 5 falls on the conveyor 20, and the dropped trimming unit 5 is conveyed to a predetermined position by the conveyor 20 as a crop and processed. . That is, a crop material extraction process is performed.
[0025]
  At the time of the cutting, the wire rod gripped by the grip device 9 remains as being gripped by the gripper 12 as the sample material 21. A portion of the sample material 21 close to the main material 6 side is provided as a real sample. This is the sample material extraction step.
  When a plurality of the cuts are cut at the same time, markings are given in advance to a portion of the plurality of wires gripped by the grip device 9 and used as a true sample material.
[0026]
  That is, in this invention, it has the marking process of giving the marking which marks the part used as a sample material by a notch, coating, or tape sticking before the said cutting process.
  16 to 17 show details of the sample material extraction step, which is a step of releasing the grip of the grip device 9 and dropping the sample material 21 downward. A sample collection conveyor 22 is disposed at the sample material dropping position. Of the sample material 21 that has fallen on the conveyor 22, the marked material is used for the real sample, and the other sample material 21 is discarded in the same manner as the crop.
[0027]
  A pusher 23 is used to drop the sample material 21 from the grip device 9. That is, when the sample material 21 does not fall by simply opening the gripper 12, the sample material 21 is dropped by the pusher 23. The pusher 23 is fixed at a predetermined position, and is configured such that when the grip device 9 is moved backward by the moving device 8, the sample material 21 is scraped by the pusher 23 and dropped. Yes.
  On the closed side, when the grip device 9 is retracted by the moving device 8, the sample material 21 collides with the C-shaped hook 3, so that the moving amount cannot be increased, and the sample material 21 is not cropped. Since it falls on the processing conveyor 20, the sample chute 24 is provided so as to be retractable, and the sample material 21 does not fall on the crop processing conveyor 20.
It is configured as follows. A sample chute 24 is also provided on the open side.
[0028]
  According to the embodiment of the present invention having the above-described configuration, in addition to the operational effect that the heavy labor work of coil trimming is reduced, the following operational effect is achieved.
  By fixing the wire to be cut, the sample can be prevented from dropping and reliable cutting can be performed.
  It is easy to reliably separate the main material 6 and the trimming portion 5 and guide the trimming portion 5 to the cutting device 14.
  Sample cutting can be performed simultaneously.
[0029]
  Crop processing and sample processing after cutting can be automated.
  The sample material 21 remaining in the clamp device 7 can be reliably dropped after the gripper is released.
  A sample close to the main material 6 can be extracted from the sample material 21 taken as a sample.
  In addition, this invention is not limited to what is shown to the said embodiment. For example, the sorting step is for facilitating the grip in the next gripping step, and can be omitted if the next gripping step does not require this sorting step.
[0030]
  Further, the sorting process can be automated regardless of the manual operation. For example, the trimming portion can be sorted by photographing the end of the coil with an imaging device and performing image processing (see FIG. 6).
  Moreover, although the cutting device 14 illustrated the hydraulic cutter as what can cut | disconnect most efficiently, other methods, such as a gas cutter, are also possible.
  Although the sample material 21 is dropped by the pusher 23, it is also possible to release only one of the grippers 12 and move only the other one to offline, and drop it there.
[0031]
  Furthermore, the gripper 12 does not need to be provided on both sides of the support arm portion 4, and may be disposed on only one side.
  Furthermore, the cutting step is not limited to cutting both the outer sides of the grip device 9 at the same time, and may be performed by cutting one side at a time. Furthermore, the wire is not limited to cutting all at the same time, but may be sequentially cut from the end of the coil 2 toward the main material 6 or vice versa.
