Description

Technical Field

[0001] The present invention relates to the packaging of lines such as welding lines into large storage containers. Examples of large storage containers include drums, boxes, and the like.

Background Art

[0002] It is known to package continuous welding lines into large containers. With this line, a series of loops arranged in a circular pattern are formed within the container to form layers of the line. Layers are added on top of each other until the container, which may require hundreds of pounds of line, is full. Each layer of line formed by the series of loops has a cylindrical shape within the container. If the container is also cylindrical, the individual loops and layers of line can be laid near the wall of the container. Some containers are square and have an octagonal liner. In such cases, the layers of line that together form a cylinder are not located as close to the inner wall of the container as in the case of a cylindrical container. The gap between the octagonal liner and the line loops can cause movement or sagging of the line within the container during shipping. Sagging of the line is generally undesirable as it requires the container to be taller than necessary (due to the initially low-density packaging of the line). Also, due to the sagging of the line, the line may become entangled when feeding the line from the container, for example, during automatic or semi-automatic welding operations.

Modes for Carrying Out the Invention

[0010] The present invention relates to the bulk packaging of wires such as welding wires. Here, the present invention will be described with reference to the drawings in which the same reference numerals are used to mean the same elements throughout. It should be understood that the various drawings need not necessarily be drawn to scale, either from drawing to drawing or within a given drawing, and in particular, the sizes of the components can be arbitrarily drawn to facilitate understanding of the drawings. In the following description, for the purpose of explanation, many specific details are set forth in order to provide a complete understanding of the present invention. However, it is obvious that the present invention can be practiced without these specific details. Furthermore, other embodiments of the present invention are possible and the present invention can be practiced and carried out in ways other than those described herein. The terms and expressions used in describing the present invention are used for the purpose of facilitating understanding of the present invention and should not be regarded as limiting.

[0011] As used herein, "at least one", "one or more", and "and / or" are all open-ended expressions that act both conjunctively and disjunctively. For example, each of the expressions "at least one of A, B, and C", "at least one of A, B, or C", "one or more of A, B, and C", "one or more of A, B, or C", and "A, B, and / or C" means A alone, B alone, C alone, both A and B, both A and C, both B and C, or all of A, B, and C. Whether in the description of embodiments, the claims, or the drawings, any disjunctive word or phrase presenting two or more alternative terms is understood to contemplate the possibility of including one of the terms, either of the terms, or both terms. For example, the phrase "A or B" is understood to include the possibilities of "A", or "B", or "A and B".

[0012] FIG. 1 shows a storage container C in the form of a rectangular box, particularly a square box 10. This box can be formed from cardboard or a material having similar structural properties. The box 10 has outer walls 12, 14, 16, and 18 that define four corners. To support a coil of wire 20 within the box 10, a polygonal liner, such as an octagonal liner 22, is placed within the outer box 10. This liner 22 can also be formed from cardboard or a similar material. The liner 22 has a plurality of vertically extending walls that are disposed against the inner walls of the box 10 or extend diagonally across the inner corners of the box. The diagonal walls of the liner 22 at the corners of the box 10 form triangular corner cavities that can be filled with reinforcing elements 24, 26, 28, 30. Instead of including a single liner, the storage container C can include a number of liner members (e.g., triangular corner inserts) that, together with the walls of the box, form a polygon within the interior of the storage container.

[0013] The wire coil 20 has a generally polygonal (e.g., octagonal) cross-sectional shape in order to conform to the shape of the liner 22. Conventional wire containers that utilize an octagonal liner hold a cylindrical wire coil. The difference in shape between the cylindrical coil and the octagonal liner results in a gap between the cylindrical coil and the wall of the octagonal liner, which may cause wire sagging during shipment. When the wire sags, the likelihood of the wire becoming entangled when the wire is fed out from the container increases. In the octagonal coil 20 in FIG. 1, the gap between this coil and the wall of the liner 22 is smaller than that of a conventional cylindrical coil. Therefore, the octagonal coil 20 is less likely to sag or has a smaller degree of sagging inside the container C than a conventional cylindrical coil.

[0014] As described below, the coil 20 is formed by a continuous wire arranged in a plurality of layers. Each of these layers is composed of a series of circular loops of wire. The diameter of each loop is slightly smaller than the width per wall of the liner 22 (e.g., about 15% smaller than the width per wall of the liner). The center of each loop is radially offset towards the wall of the liner from the axis of the box 10 and the liner 22. The series of wire loops forming the wire layer are arranged polygonally (e.g., rectangular, octagonal, dodecagonal, etc.) along the vertical wall of the liner 22 in order to conform to the shape of the liner. The polygonal arrangement of the wire loops has straight portions along the central part of the liner wall and curved or rounded vertices. Since the wire layers formed by each of the series of polygonally arranged loops are stacked in multiple layers, the wire coil takes the form of a polygon (e.g., octagon) column with a central opening and rounded vertices. While forming the loops by the rotating wire laying head of the wire coiling device, the wire loops are laid in a polygonal arrangement by moving the storage container C and / or the rotating wire laying head in the linear X-Y direction.

[0015] Figure 2 shows a part of an example of the wire coiling device 32. A continuous welding wire 34 is drawn from a manufacturing process (not shown). This welding wire 34 is drawn by a capstan 36 driven by a motor 38. A series of dancer rollers 40 maintain the tension applied to the wire. The welding wire 34 is wound around the capstan 36 by approximately 270 degrees. This provides appropriate friction and driving ability to draw the welding wire 34 across the dancer rollers 40.

[0016] From the capstan 36, the welding wire is supplied to a rotary wire laying head 42. This laying head 42 can be a generally cylindrical tube having an opening along or adjacent to the bottom of a cylinder at the bottom. The welding wire 34 passes from the capstan 36 into the interior of the laying head 42. The welding wire 34 extends through this tube and, as soon as it exits from the opening in the laying head 42, the welding wire 34 is placed within a storage container C. The laying head 42 is suspended from the upper part of the wire coiling device 32 in order to rotate around a generally vertical axis A.

[0017] The laying head 42 extends into the storage container C and rotates around the axis A. This axis A is generally parallel to the axis B of the storage container. The wire supplied to the laying head 42 by the capstan 36 is supplied at a rotational speed different from the rotational speed of this laying head. The ratio between the rotational speed of the laying head 42 and the rotational speed of the capstan 36 determines the loop size diameter of the wire loop within the storage container C. A motor 44 drives the laying head 42, for example via a drive belt. A controller 46 can control the speeds of the capstan motor 38 and the laying head motor 44 to adjust the ratio between the speeds of the two motors, thereby adjusting the diameter of the wire loop forming the polygonal coil. An example of the diameter of the wire loop is about 14 - 17 inches. However, diameters exceeding this range can be provided if necessary.

[0018] When laying the wire 34 inside the storage container C, the sensor checks the height of the wire and lowers the storage container by the controller 46. When the storage container moves downward, the laying head 42 continues to rotate, and as a result, the storage container C becomes full. Support the storage container C on an L-shaped beam 47 that is vertically movable along a guide track 48 (for example, in the Z direction indicated by the double-headed arrow). Mount an actuator such as a cylinder and piston assembly 50 and / or a ball screw actuator on the frame of the L-shaped beam and the coiling device 32, and be able to control the lowering of the storage container C when filling the storage container C with wire. When filling the storage container C, since the storage container C moves downward away from the laying head 42, it should be understood that the laying head 42 does not need to move in the vertical direction.

[0019] The coiling device 32 includes an X-Y table 52 that mounts the storage container C or a similar X-Y positioner. The X-Y table 52 can include a clip 54 or other clamping device that securely attaches the storage container C to the X-Y table. The X-Y table 52 moves the storage container C in the X and Y directions (e.g., generally in a horizontal plane) under the laying head 42 while a series of wire loops are being formed. The Y direction is schematically indicated by the horizontal double-headed arrow in FIG. 2, and the X direction is perpendicular to the Y and Z directions (e.g., in and out of the plane of the drawing). The X-Y table 52 or positioner can use a linear actuator such as a belt drive actuator, a ball or lead screw actuator, a rack and pinion actuator, a pneumatic or hydraulic actuator. During operation of the laying head 42, the movement of the X-Y table 52 is controlled such that a series of wire loops forming the layers of the coil 20 are arranged polygonally within the storage container C along the polygonal walls of the liner. In particular, these loops are arranged in an octagonal pattern set by the X-Y table 52 that moves the container C under the laying head 42. The movement of the X-Y table 52 can be controlled by a controller 46. Alternatively, the laying head 42 can be moved in the X-Y directions while the wire loops are being formed. Optionally, the X-Y table 52 can impart variable speed movement in the X and Y directions to arrange the wire loops along a curve. In certain embodiments, the wire coiling device 32 can include a turntable that can rotate the container C about the axis B in addition to movement in the X and Y directions. This turntable can, if desired, lay a series of loops in a circular pattern.

[0020] The controller 46 can include an electronic controller having one or more processors. For example, the controller 46 can include one or more of a microprocessor, a microcontroller, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), discrete logic circuits, etc. The controller 46 can further include a memory and may store program instructions that cause the controller to perform the functions attributed herein. This memory can include one or more volatile, non-volatile, magnetic, optical, or electrical media, such as read only memory (ROM), random access memory (RAM), electrically erasable programmable ROM (EEPROM), flash memory, etc. The controller 46 can further include one or more analog-to-digital (A / D) converters that process various analog inputs to the controller.

[0021] FIG. 3 shows the result of arranging the wire loops in a circular array within the octagonal liner 22, and FIG. 4 schematically shows an example of the circular array of wire loops. By rotating the laying head around the axis A of the laying head, the welding wire 34 is looped within the liner 22. The rotation of the laying head is indicated by the arrow 56. The axis A of the laying head is radially offset from the axis B of the storage container and the liner 22. While the laying head is generating a wire loop, the storage container is rotated counterclockwise by only a fraction of a rotation (e.g., 1 or 2 degrees). Rotating the storage container while generating a wire loop results in the generation of a circular array of loops. It can be seen from FIG. 3 that a part of the loops in the circular array contacts the side surface of the liner 22, while other loops do not. In the lower left part of FIG. 3, there is a gap between the loop and the liner wall. Such a gap allows the wire to sag during shipment of the wire container, and as a result, the wire may become entangled when feeding the wire from the container, and a taller container may be required.

[0022] FIG. 5 shows an example of linearly moving the storage container C in the X and Y directions under the wire laying head while a series of wire loops are being formed. FIG. 6 shows an example of a polygonal arrangement of wire loops, as seen, for example, in a layer of loops in the container C. The axis B of the storage container C can be offset from the axis A of rotation of the laying head so that the loops of wire in the polygonal arrangement are not centered on the center of the storage container. However, the axis B of the storage container C is offset towards the vertical wall of the octagonal liner 22. The amount of offset between the axis B of the storage container C and the axis A of rotation of the laying head can depend on the diameter of the wire loops and thus on the rotational speed of the capstan and the laying head. A larger offset between the axis B of the storage container C and the axis A of rotation of the laying head is used to form smaller wire loops, and as a result, these loops are arranged along the walls of the liner 22. When forming larger wire loops, the offset between the axis B of the storage container C and the axis A of rotation of the laying head is reduced. The offset between axis A and axis B can be controlled by the controller 46 (FIG. 2) based on the desired loop diameter. To minimize the gap between the wire loops and the inner wall of the liner 22, the wire loops can be arranged within the liner such that each of the wire loops contacts at least one of the walls of the octagonal liner 22 tangentially. This can be achieved by appropriately offsetting the axis B of the storage container C from the axis A of rotation of the laying head and moving the storage container linearly in the X-Y direction while forming the wire loops. When moving the storage container C while forming the wire loops, the offset between the axis B of the storage container C and the axis A of rotation of the laying head changes, for example increases or decreases, as the storage container is moved in an octagonal pattern as indicated by the arrows in FIG. 5. An example of the offset between the axis B of the storage container C and the axis A of rotation of the laying head is half the difference between the inner width of the liner 22 (the distance between the opposing vertical walls for each wall) and the diameter of the wire loops when the axis B of the storage container and the axis A of rotation of the laying head are aligned with the centers of the opposing vertical walls of the liner. In a particular embodiment, the loop size can be adjusted while filling the container C, and as a result, some layers of wire are formed by loops of a first diameter and other layers of wire are formed by loops of a second diameter different from the first diameter.In such an embodiment, during the filling of the storage container, the offset between the axis B of the storage container C and the rotation axis A of the laying head can be adjusted and controlled to accommodate loops of different wire diameters.

[0023] As shown by the arrows in FIG. 5, the storage container C is moved in an octagonal pattern by the X-Y table 52 (FIG. 2) or a positioner so as to lay a wire loop in an octagonal array that conforms to the shape of the liner 22. The pattern and direction of the arrows in FIG. 5 are exemplary, and the storage container C can also be moved in the opposite direction (e.g., a clockwise octagonal pattern) and in other patterns (e.g., a square or other polygonal pattern). To arrange the wire loops in an octagonal pattern, the X-Y table or positioner moves the storage container C in eight different linear directions on the X-Y plane while the wire loop is being formed by the rotation of the laying head. The diameter of the wire loop is controlled by the rotational speeds of the capstan and the laying head, and the placement of the wire loop in the storage container C is controlled by the movement of the X-Y table or positioner. Preferably, each wire loop contacts at least one of the vertical walls of the liner 22 tangentially to minimize the gap between the wire coil and the wall of the liner. However, some loops may not contact the wall of the liner, while other loops (e.g., most of the loops) do. When moving the storage container C in an octagonal pattern, the axis B of the storage container moves around the axis A of rotation of the laying head in the X-Y direction in an octagonal pattern so as to lay the wire loop against the vertical wall of the liner 22. In certain embodiments, the storage container C can also be rotated by a turntable while the wire loop is being formed within the storage container, and such rotation can be performed regardless of the presence or absence of simultaneous movement of the storage container in the X and / or Y directions. In other embodiments, the X-Y table or positioner moves the storage container C linearly in the X-Y direction under the rotating wire laying head while forming a series of wire loops without rotating the storage container around its axis B. In certain embodiments, the laying head can be moved in the X and Y directions to lay the wire loop in a desired polygonal pattern. Alternatively, the laying head can be configured to move in one of the X and Y directions, and the wire coiling device can move the storage container C in the other of the X and Y directions, such that the laying head and the storage container move together to arrange the wire loops in a polygon while the wire loop is being formed.

[0024] Comparing the circular array of wire loops shown in FIG. 4 with the octagonal array of wire loops shown in FIG. 6, it can be seen that the octagonal array of wire loops has a straight portion S along the central part of the wall of the liner 22 and curved or rounded vertices R. Since the radius of the vertex R is large, the octagon of the array of wire loops has eight straight short sides S connected by sweeping a curve R of substantially the same length as the straight short side S. The relative lengths of the straight portion S and the curved vertices R formed by the polygonal array of wire loops are determined by the width for each inner wall of the liner 22 and the diameter of the wire loops. As the diameter of the wire loops is decreased, the length of the straight portion S of the polygonal array becomes longer, and the length of the curved vertices R connecting the straight portions becomes shorter. As the diameter of the wire loops is increased, the length of the straight portion S of the polygonal array becomes shorter, and the length of the curved vertices R connecting the straight portions becomes longer.
