Abstract
Description
- The present invention relates to a method and an apparatus for winding a wire rod which is fed from a rolling mill along a predetermined path.
- In the art of winding a wire rod which is run along a predetermined path from a rolling mill, a wire rod winder of a poling-reel type, for example, is used. In the case where billets are efficiently rolled into wire rods at relatively short intervals, the successively produced wire rods are led to alternately or sequentially selected one of plural stationary winders, along respective paths which lead to the stationary winders. More specifically, each of the wire rods from a rolling mill is first introduced into a branching or switching device which selects one of the plural wire paths that leads to the winder which is currently assigned to wind the wire rod. In this arrangement, the wire rod which is currently fed from the rolling mill is wound in the form of a coil by one of the plural winders, while the coil already wound by another winder is taken out so that this unloaded winder is able to wind a wire rod which will be fed thereto in the next winding cycle.
- In the above-described arrangement for winding successively produced wire rods, however, plural wire paths should be provided between the branching device and the respective stationary wire winders. For example, when two wire winders are used, the corresponding two wire paths should be formed so as to feed the wire rods from the branching device to the respective two winders. If it is desired to wind a wire rod in a desired one of opposite directions (either clockwise or counterclockwise) on each of the two winders, two wire paths must be provided for each of the two winders, one path for producing a clockwise coil, and the other path for a counterclockwise coil. Consequently, a total of four wire paths are required in order to enable each of the two wire winders to operate in either one of the two winding directions.
- In this connection, it is noted that each wire path extending from a branching device is formed in a line which is defined by cooling devices, pinch roll units, guide tubes, guide rolls, support post, wire inlet tube, and other members. Accordingly, the cost of the wire winding equipment and the required area of installation are increased as the number of wire paths is increased. In addition to the above inconveniences, the conventional arrangement suffers a problem that wire rods are likely to be damaged due to frictional contact with the branching device while the direction of feed of the wire rod is changed at and by the branching device, whereby the quality of the produced coil is lowered.
- It is therefore an object of the present invention to provide a method and an apparatus for winding a wire rod supplied from a rolling mill, which are capable of producing coils of wire with improved quality, at high efficiency and with minimum cost.
- According to the invention, there is provided a method of winding wire rods which are fed in succession from a rolling mill along at least one wire path, comprising the steps of: (1) providing a plurality of wire winders which are disposed, in a mutually spaced-apart relation, at one end of the wire path remote from the rolling mill; (2) positioning one of the wire winders at its winding position and winding the wire rod as a first coil by this one wire winder; (3) upon completion of winding of the wire rod as the first coil, positioning the above one wire winder to its non-winding position before the leading end of the next wire rod fed from the rolling mill reaches the above-identified one end of the wire path, and positioning another of the wire winders to its winding position; and (4) winding the next wire rod as a second coil by the above another wire winder, while concurrently taking out the first coil from the previously operated one wire winder.
- According to another aspect of the invention, there is provided an apparatus for winding wire rods which are fed in succession from a rolling mill along at least one wire path, comprising: a carriage which is movable, at one end of the wire path remote from the rolling mill, in a direction perpendicular to the wire path; a plurality of wire winders for winding the wire rods, the wire winders being mounted on the carriage such that the wire winders are disposed in the direction of movement of the carriage; and drive means for moving the carriage to position a selected one of the wire winders in its winding position.
- In the method or apparatus of the present invention described above, the wire winders are selectively brought into a winding position. Consequently, the wire rods which are successively fed from the rolling mill at relatively short time intervals may be led to selected one of the plural wire winders, without branching the wire path originating from the rolling mill, into plural branch paths corresponding to the plural wire winders. In other words, the wire rods may be supplied to the appropriate wire winders along a single wire path. Thus, the instant winding method or apparatus makes it possible to achieve a considerable reduction in the number of components of the wire path arrangement such as branching device, cooling device, pinch rolls, guide tubes, guide rolls, posts and wire inlet tubes, whereby the overall cost of the equipment and the installation space may be minimized. Moreover, the elimination of a branching device frees the wire rods from otherwise possible bending stresses and consequent frictional damages when the direction of feed of the wire rod is changed at the branching device.
- According to an advantageous embodiment of the apparatus of the invention, the carriage may be a truck having wheels which roll on rails extending in the direction perpendicular to the wire path. In this case, the drive means for moving the truck may comprise a hydraulic cylinder.
- According to another advantageous embodiment of the invention, each of the wire winders comprises a substantially cylindrical drum which is rotatable about its vertical axis and open at its upper end. The wire rod is introduced through the upper open end and wound in the cylindrical drum.
- In accordance with a further advantageous embodiment, the wire rods are fed from the rolling mill along a single wire path to the carriage, and the plural wire winders consist of two wire winders which are spaced from each other in the direction perpendicular to the wire path.
- The foregoing and other objects, features and advantages of the present invention will be better understood from reading the following detailed description of a preferred embodiment of the invention, when considered in connection with the accompanying drawing, in which:
- Fig. 1 is a schematic plan view of billet rolling and wire winding equipment which includes one embodiment of a wire winding apparatus of the invention;
- Fig. 2 is an elevational view of a wire winding apparatus taken along line II-II of Fig. 1;
- Fig. 3 is an elevational view of the wire winders taken along line III-III of Fig. 1; and
- Fig. 4 is a schematic plan view corresponding to Fig. 1, showing a known arrangement of billet rolling and wire winding equipment.
- To further clarify the concept of the present invention, a preferred embodiment of the invention will be described by reference to the accompanying drawing.
- Referring first to Fig. 1, there is shown a general arrangement of billet rolling and wire winding equipment constructed according to the invention, which is suitable for practicing the method of the invention. The equipment comprises a finish rolling-
mill stand 10 which is disposed as the last stage of a hot-rolling process. Awire rod 14 fed from the rolling-mill stand 10 is guided along alinear wire path 12 which leads to a carriage in the form of atruck 20. Thetruck 20 carries thereon twowire winders wire path 12. Thetruck 20 is movable in the direction in which the twowire winders wire path 12. Thewire path 12 is formed in a line which is defined byplural cooling devices 22 for cooling thewire rod 14,pinch rolls 24 for guiding thewire rod 14, and other members necessary to guide thewire rod 14 to thetruck 20. - As illustrated in detail in Figs. 2 and 3, there is formed a
pit 26 in the ground floor. Onshoulders 29 which partially define thepit 26, a pair ofrails 28 are laid in parallel with each other, so that therails 28 run perpendicularly to thewire path 12. Thetruck 20 is adapted to move with itswheels 30 rolling on therails 28. More specifically stated, thetruck 20 is connected at its one end to apiston rod 36 of ahydraulic cylinder 34 which is fixedly disposed in thepit 26, so as to serve as a major component of drive means for moving thetruck 20. This drive means further includes limit switches (not shown) which are disposed at four positions along therails 28, so that thepiston rod 36 and consequently thetruck 20 may be moved to a desired one of four positions corresponding to the positions of the limit switches. The four positions of thetruck 20 correspond to two winding positions of a first poling reel 38 (which will be described), and two winding positions of a second poling reel 40 (which will be described). One of the two winding positions for eachpoling reel wire rod 14 into a clockwise coil, and the other winding position is for winding thewire rod 24 into a counterclockwise coil. Thus, thetruck 20 is positioned selectively at one of the four winding positions. - The
wire winders truck 20 are of so-called "poling reel" type, each including the previously indicatedpoling reel winders - The
poling reel 40 is rotated by adrive motor 42 via areduction gear 43, and closed at its bottom end by asupport disc 44 as indicated in Fig. 2, while thewire rod 14 is wound in thereel 40. Thesupport disc 44 is movable in thepoling reel 40 in the vertical direction, by anelevator rod 46 which is disposed co-axially with thepoling reel 40 and movable up and down along the axis of rotation of thereel 40. Described in greater detail, theelevator rod 46 whose upper end is secured to thesupport disc 44, is operatively connected at its lower end to ahydraulic cylinder 50 through alever 52 and alink 54. Thehydraulic cylinder 50 is fixed to abracket 48 which extends downward from the bottom of thetruck 20. Thelever 52 is pivotally supported on thebracket 48 and connected at its opposite ends to thecylinder 50 and thelink 54, respectively. Linear movements of thehydraulic cylinder 50 will cause thelever 52 to pivot in opposite directions, thereby moving theelevator rod 46 up and down via thelink 54. In this arrangement, thesupport disc 44 at the upper end of theelevator rod 46 is held at its lower position indicated in broken line in Fig. 2 while thewire rod 14 is being wound as a coil in thepoling reel 40, but after the completion of the winding cycle, thedisc 44 on which the coil is wound is moved upward to its upper position upon activation of thehydraulic cylinder 50, so that the coil may be pushed out of thepoling reel 40. - Adjacent to the edge of the
pit 26, apost 56 is erected for supporting in a known manner awire inlet tube 58 which forms the terminal portion of thewire path 12. Thiswire inlet tube 58 through which thewire rod 14 is passed, is oriented so that thewire rod 14 is led into an upper part of the poling reel 40 (38). Depending upon the specific thickness (diameter or cross sectional area) of thewire rod 14, the vertical position and angle of inclination of thewire inlet tube 58 with respect to thepost 56 are changed as illustrated in solid and broken lines in Fig. 2. Namely, the angle of the terminal portion of thewire path 12 is suitably adjusted to the thickness of thewire rod 14. Alternatively, it is possible to use a switching device to branch the terminal portion of thewire path 12. - The operation of the present embodiment will be described.
- In the case where the
wire rod 14 is wound as a counterclockwise coil by thewire winder 18, thetruck 20 is moved to the position indicated in solid line in Fig. 1, i.e., to a winding position of Fig. 3, for positioning thepoling reel 40 so that thewire inlet tube 58 points into the upper open end portion of thepoling reel 40. More precisely, thetruck 20 is positioned so that the left-hand side end (as viewed in Fig. 3) of the upper open end of thepoling reel 40 is aligned with thewire inlet tube 58, as shown in Fig. 3. In this position, thepoling reel 40 is rotated at a peripheral speed substantially equal to a feed speed of thewire rod 14 which is fed from the finish rolling-mill stand 10 which produces thewire rod 14 by rolling a billet. With thewire rod 14 fed into the rotatingpoling reel 40, thewire rod 14 is wound as a counterclockwise coil in thereel 40. While the winding operation is being performed on thepoling reel 40, the coil already wound in theother poling reel 38 is removed out of thereel 38. - Upon completion of the winding cycle in the
poling reel 40, thetruck 20 is moved by thehydraulic cylinder 34 to another winding position, indicated in broken line in Fig. 1, at which thewire inlet tube 58 is brought into alignment with the upper open end of theother poling reel 38, before the leading end of thenext wire rod 14 reaches the polingreel 38. Thus, thetruck 20 is positioned so that thewinders - Subsequently, the
new wire rod 14 is wound in thepoling reel 38 as a clockwise coil. In the meantime, thesupport disc 44 in thepoling reel 40 is raised to take out the counterclockwise coil which has been produced in thepoling reel 40. - With the above winding cycle repeated, the
wire rods 14 which are successively fed along thesingle wire path 12 from the finish rolling-mill stand 10 at relatively short time intervals, may be wound alternately by one of the twowire winders wire rods 14 in the counterclockwise direction in thepoling reel 38, or in the clockwise direction in thepoling reel 40, this winding operation in the reverse direction may be readily accomplished by moving thetruck 20 to change the winding position, so that thewire inlet tube 58 is aligned respectively with the left-hand side edge and the right-hand side edge (in Fig. 3) of the polingreel reels poling reels truck 20 are movable, there is no need to branch thesingle wire path 12 for feeding thewire rod 14 to different positions for clockwise and counterclockwise winding operations for each poling reel. - As described hitherto, the instant winding system or apparatus and method are adapted to efficiently handle the
wire rods 14 which are fed in succession from the finish rolling-mill stand 10 at comparatively short intervals, and along thesingle wire path 12. In other words, the successively fedwire rods 14 are wound alternately in one of the twowire winders winders wire path 12, such as branching device, cooling device, pinch rolls, guide tubes, guide rolls, support post and wire inlet tube. Consequently, the cost of the wire winding equipment as a whole, and the installation area required, are reduced to an appreciable extent. Further, since the instant apparatus does not require a branching device for feeding the wire rod along one of plural wire paths as used in the conventional system, thewire rod 14 is not marred or otherwise damaged due to a bending force applied during a pass through the branching device. Thus, the conventionally encountered deterioration of quality of the produced coils is eliminated, or at least minimized. - For comparison, an example of a conventional system is shown in Fig. 4, wherein a single wire path originating from a finish rolling-
mill stand 70 is branched by a branchingdevice 76 into two wire paths which lead to twostationary wire winders wire rods 75 are wound selectively in the clockwise or counterclockwise direction in each of the twowinders - While the present invention has been described in its preferred form, it is to be understood that the invention is not confined to the precise disclosure contained herein, but may be otherwise embodied, with various changes, modifications and improvements.
- For example, the
truck 20 which carries thewire winders wheels 30 rolling on therails 28 by thehydraulic cylinder 34, may be moved by an electric motor. Further, thetruck 20 may be replaced by a carriage or other forms of movable means, which is movable by means of a slide slidable on a suitable bearing surfaces, or by means of a suitable link mechanism. Further, the carriage may be replaced by a rotary turning table which is rotatable about the vertical axis. - While the
truck 20 carries the two winders in the illustrated embodiment, three or more winders may be mounted on the truck or similar movable means indicated above. - The
poling reels - It will be obvious to those skilled in the art that other changes and modifications may be made, in view of the foregoing teaching, without departing from the scope of the invention defined in the appended claims.
