Figs. 1-6 show the first rotary assembly and schematically produce a coil of continuous flexible product 2 in a stationary winder 3 located at the factory. In order to simplify the description and in the embodiment of the device according to the present invention, in the following description the product 2 is presented as a wire or cable. However, the invention can be applied to other types of products that are easily susceptible to bending, i.e. products from which coils can be formed or wound onto cylindrical cores, such as wires, steel ropes, ordinary ropes, cords, straps, hoses, chains and the like. Winder 3 has two support arms 4, 5 rotating about a horizontal axis, on which there is a spool holder, having the form of two coaxial mandrels 6, 7. The support arms 4, 5 can slide relative to each other, which allows the pins 6, 7 to move from the free initial position shown in Fig. 3 to the working position shown in Fig. 4a in which the two pins 6, 7 have been pushed together along their axis. One of the mandrels is driven by a motor 8. The winder 3 is equipped with an easily mounted and dismantled first auxiliary device 9, intended for multiple use at the factory. As shown in fig. 1 the device 9 consists of two round, similarly shaped wheels, side rims 10, 11 made of metal, e.g. steel or aluminum, and a longitudinal metal connector 12, used to keep both side rims 10,11 fixed relative to each other. The connector 12 has a central hole 37 running along its axis (Fig. 2b) and consists of a hollow shaft 13 of a certain length and a hollow locking element 14 having an external thread 15 and a wheel 16 to facilitate turning. At one end of the shaft 13 there is a flange 17, which is a retaining element, while at the other - an internal thread 18, into which the thread 15, located on the locking element 14, can be screwed. An alternative solution is to replace the flange 17 with a locking element similar to element 14, and also thread the other end of the shaft 13. In both cases there is both a connector 12 and side rims 10, 11 with an element enabling them to interact with each other or with a pusher (not shown) , so that they are connected to each other, which allows them to jointly rotate. Each side rim 10, 11 includes an outer, durable, tubular, round ring 19, hub 20, and a number of spokes 21 that support and center hub 20. Holes are formed between the spokes
168 767 functional 89. The hub 20 has a central hole 22 (indicated in FIG. 2b by a dashed line), whose center corresponds to the diameter of the shaft 13, thanks to which the shaft 13 can be inserted into the hole 22, leaving no gap between the surfaces of both elements, deteriorating stability or centering. Each side rim 10, 11 has an inner side formed by spokes 21 and working surfaces 23, located at a distance from the hub 20 and lying in the same plane parallel to the plane of the respective working surfaces 23 on the second side rim 11 or 10. In addition each lateral rim 10, 11 has on its inner side a concentric centering hub 24 with a specific axial length and a specific radius, concentric with the hub 20. In the embodiment shown, the centering element 24 consists of three uniformly distributed blocks in the shape of circular arches between which functional openings are formed 25. The working surfaces 23 of the spokes 21 are located in the radial direction outwards in relation to the centering elements 24. Centering elements 24 have a number of respective guide protrusions 26 whose outer surfaces are inwardly inclined. The guide protrusions 26 are arranged inside a conical surface formed by their outer surfaces.
Core 28 and two round, annular, flat protective shields 29, 30, locked on core 28, are used to make the conduit or cable package 27, said disks 29, 30 forming the walls of the finished conduit or cable package 27. Thus, the core 28 is the inner frame or the support of the packet or coil. Core 28 is a non-deformable, cylindrical, axially open, sleeve of defined length and diameter. The wall thickness of the sleeve ensures that the deformation resistance is maintained under the influence of forces that can affect the wire or cable packet. The undeformable sleeve 28 is resistant to climatic conditions, due to which it does not absorb moisture or water, for a longer period of time, preferably for at least three months, in contact with water. Its internal diameter is equal to or only slightly smaller or larger than the diameter of the centering element 24, so that the element 24 can enter into the holes at the ends of the sleeve 28, with no gap being created between the respective surfaces of both parts, which ensures accurate centering of the sleeve 28 in the auxiliary device 9. Said strictly defined axial length of the centering element 24 is selected in such a way that the sleeve 28 applied thereto is properly supported in the radial direction. The end surfaces 31, 32 of the sleeve 28 are parallel, which ensures parallelism of the side rims 10, 11 in the working position assembled in the winder 3. Thus, the end surfaces 3132 contact the bearing surfaces 23 formed by the spokes 21. The protective discs 29.30 have a round hole 33 in the middle with a slightly larger diameter (see also Fig. 27) than the outer diameter of the sleeve 28, which facilitates the application of both protective discs 29, 30 on the sleeve 28 in such a way that they enter their end surfaces . The outer surfaces 34 (Fig. 1) of the protective shields 29, 30 are flat and when winding lie in the same plane as the end surfaces 31, 32. This plane is also the same plane in which the bearing surfaces 23 formed by the spokes 21 lie. The outer diameter of the protective shields 29, 30 is slightly smaller than the diameter of the side rims 10, 11. Near the outer edge of each protective shield 29, 30 there is a number, e.g. three, small holes 35 (see Fig. 2b), evenly distributed around the perimeter. Their role will be presented later in the description.
The three components described so far, constituting the components of the finished package 27 of the wire or cable, i.e. the sleeve 28 and two protective shields 29.30, are mounted on the auxiliary device 9 by means of a hollow shaft 13, inserted through one of the side rims 10, 11 and inserted through the axially open sleeve 28 on which protective shields 29, 30 were previously mounted. At the same time or earlier, a second side rim 11 is moved to the second end 32 of the sleeve 28, and the shaft 13 is inserted into the central hole 22 of the hub 20. The next step is to screw the shaft 13 to the rotation 13, while the centering elements 24 are inserted into the sleeve 28, whereby it is clamped between the side rims 10, 11, as shown in Fig. 2a. Mounting of sleeves 28 on centering elements 24 is facilitated by guide protrusions 26. Connection of bushing 28 with elements
168 767 centering 24 is detachable, i.e. there is no need to use any permanent mechanical or chemical connection here. The first rotary assembly 36 thus formed, whose axis of rotation defines the central opening 37 of the connector 12, is then forced into the winder 3. Then the mandrels 6, 7 are introduced into the central hole 37 in the shaft 13 and the locking element 14, after which the rotary assembly 36 is raised to the winding position, as shown in Fig. 4a. The end of the wire or cable 2 is inserted through an opening or recess 38 (see Fig. 27) in one of the protective shields 29.30, which allows it to be attached to the rotary assembly 36 when the assembly rotates about a central axis or a rotation axis. Said axis of rotation is arranged coaxially with the axes of the pins 6, 7, so that the rotary assembly 36 is rotated in the direction shown in Fig. 4b (in this figure the wheel 16 is omitted). The protective discs 29, 30 are attached to the side rims 10, 11 by means of suitable fastening elements 39 (see Fig. 27), so that they rotate with them. Prior to attachment, the protective shields 29, 30 are rotated so that the circumferential holes 35 are aligned in pairs and coaxial, and that they are inside the circular slices in which said holes 25 of the centering element 24 (see e.g. Fig. 4b). The wire or cable 2 is wound on the sleeve 28 as it rotates, resulting in a coil 1 with a precisely defined diameter, the diameter being slightly smaller than the diameter of the protective shields 29, 30, as seen in Fig. 5. Then the arms 4, 5 lower the assembly 36 with the coil 1 of the wire or cable, after which the mandrels 6, 7 are removed. The whole assembly with the coil 1 of the wire or cable is rolled back to the adjacent final wrapping station, as shown in Fig. 7 and 8, where first the entire outer surface of the roll 1 is surrounded by a plastic or cardboard protective sleeve 40 cut along the axis, as shown in Figs. 7a and 7b. In the next stage, fastening elements in the form of bands 41 are threaded through the side hoops 10, 11, the sleeve 28 and the holes 35 in the protective shields 28.29. The bands 41 are heavily stressed and their ends are permanently tied after stretching. Thus, each band 41 extends in the axial direction of the sleeve 28, and transversely to the individual windings 1 of the wire or cable in the form of an endless loop. Ties 41, usually made of metal or reinforced plastic, surround the sleeve 28, protective rings 29, 30, coil 1 and protective cover 40, resulting in a finished package 27 of the wire or cable in which the product is well protected and strongly compressed due to which individual coils of 1 wire or wire are tightly connected with each other and cannot move at all. Between the protective rings 29.30, spacers can be inserted to support the bands 41 and prevent them from breaking the product, especially if the protective housing is thin and the cable or cable is fragile.
An alternative solution is to permanently mount the auxiliary device 9 on the support arms 4, 5 in such a way that the side rims 10, 11 can move relative to each other by means of the support arms. In this case, the alignment and attachment of the sleeves 28 between the side rims 10, 11 also takes place as described above. In this situation, the connector 12 can be dispensed with, while the central hole 22 of the hub 30 can be used as the fastening element into which e.g. pins 6, 7.
Figure 27 shows an exemplary design solution of the protective disc 29, 30, on which one surface there is a fixing element 39 in the form of six short pins. The fixing pins 39 are placed in pairs on both sides of the spokes 21 located on the side rim 10, 11. Both pins 39 in each pair are at such a distance from each other that the spokes 21 freely pass between them. In addition to the circumferential holes 35 through which the straps 41 are threaded through, a recess 38 in the edge of the central hole 33 is also shown. Before the winding begins, the end of the cord or rope is pulled through this recess and secured accordingly. In the above-described embodiment of the protective shield construction 29.30, the central bore 33 forms the inner concentric bearing surface 42 cooperating with the adjacent outer surface of the sleeve 28.
Figure 28 shows another embodiment in which the protective disks 29, 30 are releasably connected to the sleeve 28 by their internal surfaces. On one side of them
168 767 has an axially protruding concentric flange 43 surrounding the central opening 33. Flange 43 has an outer, concentric, cylindrical bearing surface 44, to which it is connected in a detachable manner, the corresponding inner surface of the sleeve 28. Flange 43 has a corresponding conical surface centering 45. On the outer edge of the protective sleeve shown in Fig. 28 there is a recess 35 through which the straps 41 are pulled.
Auxiliary device 9 with a ready packet of wire or cable is pressed onto the ramp 46 in such a way that the side rims 10, 11 can detach from the ground, as shown in Figures 9a and 9b. With this solution, the auxiliary device 9 can be dismantled and removed from the finished wire or cable packet 27, as shown in Figs. 10a and 10b. The package 27 is then rolled over the ramp 46 and placed in the cradle 47 for loading, as shown in Figures 11 a, 11b and 11c. The next step is to transfer the package 27 by means of the expansion handle 48 to the pallet 49. The expansion handle 48 is lowered into the cylindrical space in the sleeve 28 and blocked on its inner surface, as seen in Figs. 12a and 12b. Several, e.g. two, ready-made wire or cable packages 27 can be placed on each pallet 49, as shown in Figure 12b. Pallets 49 with packages 27 are loaded onto a transport vehicle by means of a forklift 51 as shown in fig. 13a and 13b, which transports them to the place of assembly works. Thus, according to the invention, the term package refers to packaging ready for direct transport to the user, this may occur after storage.
The unloading of the wire package or cable packet 27 at the site of works is carried out by means of the same or different, similar expansion clamp 48, as shown in Fig. 14a. During unloading, it is possible to lower the package 27 on the subassemblies of the second auxiliary device 52 (see Fig. 14b), with a simple design that allows its multiple assembly and disassembly on site. The second auxiliary device is used as the device necessary for unwinding the wire or cable 2. Its design is similar to the design of the auxiliary device described above, used in the winder, in terms of the number, type and basic design features of the main assemblies, and therefore it consists of two identical, made of metal such as steel or aluminum, side rims 53, 54 and an elongated metal connector 55, with a central hole 59 running along its axis (Fig. 15d), consisting of a hollow shaft 56 with a flange and a hollow locking element 59, used to connect and attach together the side rims 53, 54. The shaft 56 passes through the central hole in one of the side rims 53, 54 and takes a vertical position, because rim 53 lies on the ground. When lowering the wire or cable package 27, the hole therein enters the shaft 56 together with the central space of the expansion handle 48, whereby the package 27 can be lowered onto the rim 53. The expansion handle 48 is released and removed, then onto the upper part of the package 27 a second rim 54 is applied (see Fig. 15a). A locking element 57 is screwed into the thread in the shaft 56 and tightened in such a way that simultaneously the packet 27 of the wire or cable is clamped between the rims 53, 54 and the centering of the sleeve 28 by means of the centering elements 58 on the rims, which in this case can be full rings. As a result, the rim axes become coaxial with the axis of the sleeve and the package 27. The second rotary assembly 60 thus obtained is then raised to a standing position by means of a rope 84 with a hook (see Figs. 15b, 15c and 15d). The next step is to insert into the central hole 59 in the connector 55 of the elongated mounting shaft 61. The ends of the shaft 61 are seated and secured in the unwinding stand 62 in such a way that free rotation of the auxiliary device 52 and cable or cable packet 27 on the shaft 61 (see Fig. 16a) . The straps 41 and the removable protective housing 40 are then cut, as shown in Fig. 16b, after which the free end of the wire or cable can be connected to one end of the pull rope 69 (see Fig. 17), the other end of which is in another distant place, in which the rope is wound. After unwinding the wire or cable (Fig. 18), the empty second assembly 60 is removed from the unwinding stand 62 (Fig. 19a) and the device is dismantled (Fig. 19b) for reuse. In contrast, bushing 28, protective shields 29, 30 and protective housing
168 767
40, are disposable packaging and are incinerated at the place of works or scrapped.
At the aforementioned second place of works, a third auxiliary device 63 (see Fig. 20) is used, easy to assemble and disassemble. The device 63 is similar to the device used in the stationary winder 3 for unwinding in the first place of works in terms of the number, type and basic design features of the main assemblies, and therefore consists of two identical, made of metal such as steel or aluminum, side rims 64, 65, and the elongated metal connector 66, with a central hole 85, extending along its axis (Fig. 21b), consisting of a hollow shaft 67 with a flange and a hollow locking element 68, intended for joining and fixing the side rims together. The third auxiliary device 63, used repeatedly at the site of the works, is folded in a similar way as the instruments 9, 52 described above with simultaneous centering and clamping of the sleeve 28a (see Figures 21a and 21b) on which the hauling rope 69 is to be wound. A longitudinal shaft 71 is inserted into the central hole 67 of the connector 66, obtained in this way of the third rotary assembly 70 (see Fig. 16a). The ends of the shaft 71 are placed and secured in a winding stand 72 (see Fig. 22), equipped with a drive motor 73 and a device for transmitting the drive to the apparatus 63 and sleeves 28a via the shaft 71. The joint rotation of these components is achieved by means of suitable push rods 88 connected to the auxiliary device through holes 74. The winding stand 72 is suitably rigid mounted on a transport trolley 82, equipped with a folding flap 83. Since in this case there is no need to connect the protective discs 29.30 with the bushing 28a, the side rims 64.65 have, for example, sheet metal walls 75, being the direct supporting elements for the hauling rope 69. In the walls 75 there are radial holes 76 in line with the axial holes 77 (Fig. 20) in the centering elements 78. Holes 76.77 allow wrapping the finished coil 79 with bands 80 in the same way as it is done during the production of the wire package 27. Preferably, the sleeve 28a is an hollow sleeve 28 obtained during the previous unwinding of the product, made of a material that can be burned during remelting of a scrapped coil of wire or cable, which in this case is a hauling rope 69, at the remelting department of the pipe manufacturer. Thus, the coil 79 is transported to the smelting plant in the form of an unpacked packet 81, in which the individual coils of the cord are connected to each other by means of bands 80.
Alternatively, the second and third auxiliary devices 52, 63 can also be permanently attached to a handle that can be on a vehicle or transport trolley, which handle may include support arms that allow parallel movement of the side rims for clamping and releasing sleeves 28, 28a, with or without a coil. In this case, you can opt out of connector 55, 56.
In the described embodiment, the design of the auxiliary devices together with the sleeves allows them to be mounted so that they can rotate around a horizontal axis. The invention has created the possibility of depositing auxiliary devices in such a way that they rotate about a vertical axis, as shown in Fig. 26. The advantage of such a solution, especially in the case of unwinding of the coil, is the possibility of eliminating the unwinding stands and easier selection of the place where the unwinding occurs. This is because the expansion handle 48, which in this case has the ability to rotate about a vertical axis, can be coupled to one of the side hoops 53, 54 by means of tabs 86. After this coupling, auxiliary device 52 with a package of wire or cable 27 it is lifted by means of handle 48 in a manner enabling it to rotate freely about the vertical central axis of handle 48. The handle 48 can be mounted on a suitable vehicle 87, which simultaneously serves to transport the device together with a wire or cable packet to a suitable work site at the power line installation, where the unwinding of the wire or cable begins.
Protective shields 29, 30, forming a durable packaging for both ends of the wire or cable packet, protecting the coil 1 during handling and transporting the packet 27, simultaneously act as auxiliary supports for side rims 10,11; 53.54. Therefore, when you design them, you can save on materials and use holes in them
168 767 relieving, as in the case shown, where spoked wheels were used. With this design solution of 10.11 spoked wheels; 53.54, there is an easy way to couple the assembled second assembly 60, consisting of a cable packet 27 or cable and second auxiliary device 52, to the jack by means of rope 84 with a hook, e.g. as shown in Fig. 15b, without exposing the entire assembly to harmful loads.
The sleeve 28 may be one piece, as shown or, for example, consist of two cylindrical halves joined together by means of the surrounding protective rings or, if necessary, by means of a suitable joining element or mechanism. The split sleeve takes up less space before using it in the winder 3, because its halves can be inserted one into the other, which saves on expensive space during transport and storage. The sleeve 28 can be made of cardboard, wood fibers, such as chips or sawdust, or of plastics. Preferably, the method of winding the cardboard sleeves should be parallel. Preferably, wood fiber sleeves should be made by pressing a mixture of wood fibers and a suitable binder with non-hazardous properties. Protective shields 29, 30, like sleeves, can be made of wood fiber and manufactured by pressing, or they can be made of plastic or wooden boards, e.g. plywood. The sleeves and protective rings are weather resistant, thanks to which they withstand moisture and water in very extreme conditions in the open air for a period of preferably at least three months. To this end, they can be preserved, during or after the production process, by means of a suitable protective substance, such as paraffin, which gives the material the desired hydrophobic properties.
New packaging materials are used to manufacture each 27 wire or cable packet, which includes a sleeve, protective rings, and protective covers. These materials are not materials with variable properties, thanks to which: winding can be carried out with appropriate accuracy, which is possible due to the stability of dimensions of packaging materials; no loads act on the scroll; as part of the roll, there is no movement of the product before unwinding, due to the expansion or contraction of materials, as is the case with known wooden spools. During transport and storage, no connectors protrude from the center of the cord or cable pack. The binding elements, i.e. the band 41, make contact with the inner part of the sleeve or are close to its inner part, i.e. at a distance from its center. Therefore, it is possible to insert inside the sleeves of handles enabling safe lifting of a cable packet or cable, and even hanging it in a way that allows it to rotate around the vertical axis of the handle, which gives a completely new, simplified unwinding technique.
The length of the sleeve is selected according to the amount of wire or cable to be included in the package. Therefore, you can use protective rings of several different sizes, corresponding to different lengths of wires or cables, ordered by users.
Thus, the auxiliary devices described above are intended for multiple use at suitable work locations and are made of metal, which ensures their long life and the required stability of the three rotating units. The remaining material included in the package, i.e. the packaging, is a single-use material. The auxiliary devices themselves are to be constructed as elements for hanging the sleeves with or without the coil in the appropriate holders of the stationary winder and transportable winding and unwinding devices used in the works.
