Description

DESCRIPTION

A MACHINE PERFORMING THE CABLE WINDING IN THE FORM OF COIL AND

SPOOL

Technical Field

The present invention relates to a machine, which enables the packing of the cables in the form of coil or spool in the same machine, has at least two winding heads and secures the end of the wound cable remaining outside the spool or coil with a stretch film made of such materials as polyethylene, PVC, etc.

Background of the Invention Various methods and machines are known to exist for packing the cables in the form of spool or coil. In the existing machines, it is not possible to carry out the winding process in the form of both coil and spool on the same machine. For this reason, more than one machine are used to obtain the coil and spool forms, with it being possible for the number of said machines to rise up to four.

In the application no. PCT/TR2007/000117, a machine capable of winding in both coil and spool forms is mentioned, but only one winding head is used in said machine and therefore, the production rate is low. Some of the existing coil winding machines attach a band on the coil to prevent the package from breaking up or utilize the weight of the package to secure the remaining end of the material in coil form.

In some of the cable coiling machines available in the market, the end of the cable located on the coil is tied with a circular strap in order to prevent the coiled package from breaking up. In such type of packing, it becomes difficult to tie the cable end with a circular strap in case the cable in coil form is soft and flexible. The strap used for this purpose causes the distortion of the shape of the coil, and also, since the strap tying process may not be performed in the winding head, the transfer of the package in coil form to another strapping station is necessary. These processes lead to the distortion of the physical form of the package and also to a packing progress that becomes difficult to complete.

The application no. EP 1181229 discloses a device and method applied to wind the cables, wires, ropes or similar items in coil shape. It is disclosed that in said cable winding machine the cable is wound on the core of the reel head of the device, the end piece of the cable is secured by means of the weight of the wound coil, the wound coil advances on the support and meanwhile, the end piece of the wound coil is located between the support and the wound cable coil, and thus the cable coil is saved from the danger of becoming untied.

Although the aforesaid solutions represent an obvious improvement over the existing systems, they have some disadvantages. One disadvantage lies in the fact that the securing of the end of the cable wound in coil form is performed by utilizing the weight of the coil and by squeezing the remaining end under the wound cable, and therefore the preservation of the wound coil form and the prevention of the breakup of the coil may not be guaranteed during its removal from the winding head. Another disadvantage of this type of packing is that the outer coil diameter is in compliance with the machine dimensions and thus there is the necessity to operate with a fixed outer diameter.

Another disadvantage is the inability to perform a conductivity test (measurement) between the two ends of the wound coil, because the end of the coil is located underside and it may not be left outside in a controlled manner. As described above, except the machine with single winding head and low production rate mentioned in the application no. PCT/TR2007/000117, the spool and coil packing are not performed in the same machine according to the existing systems, and different machines are needed for this purpose. Consequently, various machines employed only for the spool packing are in use today.

Generally, in the existing cable packing machines with single head or two heads used in packing the spools, the beginning end of the material to be wound is fitted to the reel via a hole at the center of the reel. This condition leads to a reduction in the production rate in the operation of the machine, resulting from an increased time for fitting the end. . In some of the existing spooling machines with single or two heads, the beginning end of the cable is attached through the space on the face of the reel flange. In this case, the end of the cable remains on the outer face of the spool in an uncontrolled manner. In these machines, it is not possible to perform the checks aimed at measurement on the spool, because the end of the wound cable may not be left outside the package material wrapped around the spool, in a controlled manner.

Based on the state of the art, the present invention aims at eliminating the existing disadvantages and also providing new advantages, owing to the improvements realized in the cable winding machine.

An object of the invention is to realize the cable winding process within the shortest time possible and with the lowest possible cost. Another object of the invention is to enable winding of the cables in spool and coil form with various diameters in the machine.

Another object of the invention is to guarantee that the wound coil is removed from the winding head without any distortion in its form.

Another object of the invention is to enable the measurements for checking purposes to be performed in a controlled manner on the end of the cable.

In order to achieve the said objects, a machine has been developed, which allows the cables that may possess different properties to be wound in coil or spool form in the same machine, and has at least two winding heads. The primary advantage that is envisaged to be provided with the invention is, as indicated above, the performance of both the coil and spool winding in a rapid manner in the same machine. The figures related to said invention are presented in the accompanying pages, in which:

Description of the Invention

Said invention is a machine performing the winding of the cables in spool and coil form, said machine essentially comprising the winding station with at least two winding heads (3, 11) capable of winding spools and coils, which winding heads are located on the same plane and are symmetrical to each other, at least two stretch film wrapping mechanisms for securing the end of the wound cable that remains outside the spool or coil with the stretch film (7, 17) made of such materials as polyethylene, PVC, etc., and at least two rotational pliers (6, 16), which wrap and secure the stretch film (7, 17) around the spool or coil and also, hold the terminal end of the material cut in the spool or coil, during said process.

Winding stations and rotational holder pliers mechanisms (6, 16) may be located on the horizontal plane with the winding heads (3, 1 1) being located in the upper part and the rotational holder pliers (6, 16) being located in the lower part, and it is also possible for the winding heads (3, 1 1) to be located in the lower part and the rotational holder pliers (6, 16) to be located in the upper part or they may be placed on any plane. The operation of the invention, whose detailed view is presented in Figure-1 , occurs in two ways in which the cable is wound in the form of a spool or coil according to the parameters previously determined on the machine.

The process of packing the cable in the form of a spool may be described as follows:

The empty spools (9 and 13) coming from the spool feeding unit are placed on the winding heads (3 and 1 1 ) by means of the spool fitting pliers (8 and 15). Here, it is possible to use spools with various size. Cable (5) is placed into the channel (19) of the spool (9) (for which the detailed view is provided in Figure-4) present on the first winding head (3), and it is cut and secured at the core of the spool (9) by means of the cutting and cable holding mechanisms such as the specially designed cutter knife (20), the shoe inflatable with pressure (21 ), cable holder shoe (22) whose detailed views are provided in Figure-5, 6 and 7. When the first winding head (3) is started, the cable (5) is wound on the first spool (9) on the first winding head (3) until it reaches the previously set package length. As the previously set package length is approached, the traversing unit (2) moves towards the other winding head (1 1 ). Meanwhile, the rotational holder pliers-1 (6), previously holding the polyethylene stretch film (7), rotate to secure the polyethylene stretch film (7) around the spool (9) wound in the first winding head (3), as shown in detail in Figure 10, release the end of the stretch film (7) and grasp the cable (5). When the previously set package length is completed, the guide spools (1 ) on the traversing unit (2) position, with the help of a related mechanism, the cable (5) into the other winding head (1 1 ), (in the case of spool winding, into the channel (19) of the spool (13)).

After positioning, the special knife (20) descends to cut the cable (5) and holds the cable by its other end (5.2) seen in Figure-6 and secures the same to the spool (13), and the winding head (1 1 ) continues winding the cable (5). The previous winding head (3) rotates and wraps the stretch film (7) around the outside of the spool (9). If the terminal end of the cable (5) is to be left under the stretch film (7), the rotational holder pliers (6) leave the cable (5) at the point closest to the underside of the stretch film (7), or, if the terminal end of the cable (5) is to be left outside the stretch film (7) in a controlled manner for the purpose of enabling the measurements, the rotational holder •pliers (6), as seen in Figure-8, rotate at the same speed as the winding head (3) until the end of the stretch film wrapping process, hold the terminal end of the cable (5) and leave the cable (5) outside the stretch film (7). After the stretch film wrapping process is completed, the rotational holder pliers (6) first move in the vertical direction, then reach at the position suitable for cutting the stretch film (7), and move again downwards in the vertical direction, thus cutting the stretch film (7). The spool (9) wrapped on the outside thereof with the stretch film (7) is driven by the removal mechanism (10) onto the outlet conveyor (18). A new empty spool (9) is fitted by the spool fitting pliers (6) on the first winding head (3) that has now become emptied.

The same procedures are applied on the spool (13) on the other winding head (11 ) by the other (second) equipment and the process of winding the desired or defined amount of cable (5) on the spools (9, 13) in the winding heads (3, 11) continues in an uninterrupted manner until said process is completed.

In the winding of the coils, which is another preferred embodiment of the invention, the coil winding heads (27) shown in Figure 11 are fitted to the machine (in order to form the coil core), said coil winding heads being able to narrow and widen. Then, upon starting the first winding head (3), the packing process in coil form begins and proceeds and ends in the manner described above. In this embodiment, the spools (9 and 13) are not used. When the spool feeding units and the spool fitting pliers (8 and 15) are not fitted to the machine described in the context of the invention, said machine is produced as a coil winding machine, or when the coil cores (27) are not fitted, said machine is produced as a spool winding machine. In the embodiment of the invention in which the coil winding is performed, the terminal end of the cable (5) is secured with the polyethylene stretch film (7 and 17) without leaving the winding head (3 and 1 1 ), and thus the removal of the wound coil from the head (3 and 1 1 ) is guaranteed without any distortion in its form. Owing to the use of the spools (9 and 13) with a slotted core (19) (Figure-4) according to the invention, the beginning end of the cable is enabled to be fitted on the core of the spool by means of the cutter knife (20) and the holder as shown in Figure-5, thus enabling a very short time for fitting the cable end. As a result, the machine operates with a high efficiency when making the packages in the form of spools. The same knife and holder structure also allow the cable to be wound in coil form on the same winding head.

Another important characteristic of said invention is that during the spool or coil winding, the terminal end of the wound cable is secured with the stretch film whose detail is illustrated in Figure 9 and this permits the cable winding to be carried out in spool or coil form with different diameters in the machine.

According to the invention, owing to the holding of the cut end of the cable by means of the rotational holder pliers with details given in Figure 10, during the spool or coil winding, the terminal end of the cable may be left outside the spool or coil for the purpose of measurement and quality control. Also, the height at which the terminal end is to be left may be varied according to preference (for example, at a height of 20 mm from the bottom of the coil, etc.).

According to the invention, more than one cable holders may be used as desired.
