Description
- This non-provisional patent application claims the benefit of priority of U.S. Provisional Patent Application No. 61/699,924 filed on Sep. 12, 2012.
- The present invention relates generally to systems and methods for coiling an elongate, flexible component in the form of a coil and for subsequently sealing the coil within a protective container. More particularly, the invention is a combination coiler for winding a length of an elongate, flexible component into a coil and sealer for sealing the wound coil within a sealed container. In the exemplary embodiments herein, the invention is a combination coiler and sealer, and an associated method for coiling a length of elongate, flexible cable, wire, tubing or the like, and for subsequently encasing the wound coil within a sealed, plastic bag.
- It is common practice for lengths of an elongate, flexible component, such as cable, wire, tubing or the like to be wound into a coil. Oftentimes, the wound coil is packaged within a protective container, such as a bag or box. In certain instances, it is advantageous to encase the wound coil within a sealed, plastic bag for shipping and handling.
- Coiling machines, or “coilers,” are known for winding an elongate length of a flexible cable, wire, tubing or the like into a coil. Sealing machines, or “sealers,” are separately known for sealing a wound coil of cable, wire, tubing or the like with a plastic wrap or within a sealed, plastic bag. Typically, the coiler forms the coil and the wound coil is removed from the coiler to a strapper or binder to secure the free end of the flexible component. The wound and secured coil is then moved to a sealer where the coil is first passed through a vertical sheet of plastic to wrap the coil within the plastic sheet and the plastic sheet is then sealed to encase the coil. If desired, the coil and sealed plastic sheet are then transported to an oven to shrink-wrap the plastic sheet around the coil. Coilers are also known that wind a length of an elongate, flexible component, such as cable, wire, tubing or the like, into a coil and automatically move the wound coil from the coiler into a relatively rigid container, for example an open cardboard carton.
- The known coilers and sealers require a two-step coiling and sealing process, and in certain instances, require a three-step coiling, wrapping and sealing process, to coil a length of flexible cable, wire, tubing or the like and to encase the wound coil within a sealed plastic wrap or bag. Accordingly, the known systems and method for coiling and sealing require significant capital expense in multiple items of equipment and a substantial dedication of floor space. At the same time, the production rate of the known systems and methods is generally insufficient for cost efficient operations. Thus, a system and method for coiling a length of an elongate, flexible component to form a wound coil is needed that automatically moves the coil directly into a sealer to encase the coil within a sealed container. More particularly, a combination coiler and sealer is needed that forms a coil and subsequently automatically moves the wound coil into the sealer without reliance upon any mechanical means, such as moving arms, pushers or conveying devices. More particularly, a coiler for coiling a length of an elongate, flexible cable, wire, tubing or the like is needed that includes a sealer for receiving the wound coil and for encasing the coil of the elongate, flexible component in a closed container, such as a sealed, plastic bag.
- The present invention is a combination coiler for coiling a length of an elongate, flexible component into a coil and sealer for encasing the coil within a sealed, plastic bag. The coiler includes a feeding tube for guiding and transferring a free end of the length of the flexible component onto a central core of the coiler. The central core is rotatable to wind the flexible component about the central core in the form of a coil having a predetermined configuration. Once the coil is formed, the opposite end of the length of the flexible component is cut adjacent the feeding tube. The central core is then opened to release the coil from the central core and the wound coil is dropped from the coiler into a partially-sealed and partially-opened bag positioned beneath the coiler and disposed within the sealer. Contemporaneously, the feeding tube is moved to the central core of the coiler and the free end of the length of the flexible component is again guided onto the central core. Any open sides of the partially-sealed and partially-opened bag disposed within the sealer are then sealed to encase the coil within a sealed, plastic bag. At the same time, the central core of the coiler is rotated to form another coil of the flexible component. The sealed plastic bag containing the previously wound coil is next released from the sealer onto a conveyor positioned beneath the sealer. The conveyor may transport the encased coil into a shrink oven for shrink-wrapping the sealed plastic bag around the coil.

Regardless, thecoiler 20 and thesealer 40 are configured for use with an elongate, flexible component, for example cable, wire, tubing or the like, to form a coil of the flexible component and to subsequently encase the coil within a sealed container. Those of ordinary skill in the art will readily understand and appreciate that thecoiler 20 and thesealer 40 may be used in combination with one another in various other applications without departing from the otherwise broad intended scope of the invention. By way of example only and without limitation, thecoiler 20 and thesealer 40 are shown and described herein configured for coiling and sealing a length of an elongate, flexibleelectrical cable 50 of the type commonly utilized in electrical and communications applications. As such,cable 50 comprises at least one electrical or optical conductor disposed within a protective outer sheath. -
FIG. 1 shows a combination coiler andsealer 10 according to the present invention. If desired, operation of the combination coiler andsealer 10 may be controlled by an operator from acomputerized controller 15 provided in conjunction with the system. As shown, the combination coiler andsealer 10 includes the coiler portion, or coiler, 20 positioned slightly vertically above the sealer portion, orsealer 40. Those of ordinary skill in the art will readily understand and appreciate that thecoiler 20 may be positioned at any location relative to thesealer 40 with the addition of a means for transferring a wound coil of the elongate, flexible component from the coiler to the sealer. However, positioning thecoiler 20 vertically above thesealer 40 permits a coil of the elongate, flexible component to be dropped under the influence of gravity from thecoiler 20 in a generally vertical downward direction into thesealer 40. As a result, the number of individual items of equipment, the accompanying complexity and the floor space footprint of the combination coiler andsealer 10 are reduced. - In general, the
coiler portion 20 of the combination coiler andsealer 10 comprises acentral core 22 concentrically mounted about a shaft 24 (FIG. 3 ;FIG. 4 ). Theshaft 24 and thecentral core 22 are driven by a conventional drive means 23 such that the central core rotates in a predetermined direction. If desired, the drive means 23 may be configured to rotate theshaft 24 and/or thecentral core 22 in either the counter-clockwise direction or the clockwise direction so as to produce acoil 55 of thecable 50 that unwinds in a corresponding clockwise (right-hand) direction, or conversely, in a corresponding counter-clockwise (left-hand) direction. Thecoiler 20 further comprises a feeding tube 26 (FIG. 3 ;FIG. 4 ) for guiding a free end 52 (FIG. 4 ) of thecable 50 onto thecentral core 22, and for transferring a length of thecable 50 onto the central core under the influence of the drive means 23 to form thecoil 55. It should be noted that in certain instances it may be desirable to temporarily secure thefree end 52 of thecable 50 to thecentral core 22 so that the cable will be transferred from thefeeding tube 26 onto the central core under the influence of the drive means 23. - In general, the
sealer portion 40 of the combination coiler andsealer 10 shown in greater detail inFIG. 2 andFIG. 2A comprises a roll of asheet material 41 that is configured to be guided and delivered to the interior of thesealer 40 for sealing the wound coil of the flexible component with the plastic sheet material. As shown, thesealer portion 40 of the combination coiler andsealer 10 is movable relative to thecoiler portion 20 in a generally horizontal direction indicated by the double-headedarrow 35 inFIG. 1 . By way of example and not limitation, thesealer 40 may be moved horizontally relative to thecoiler 20 over the floor of a manufacturing and/or production facility. In this manner, thesealer portion 40 may be moved into a position beneath thecentral core 22 of one or another ofmultiple coiler portions 20, and then subsequently moved horizontally (towards the right-hand side of thesystem 10 in the configuration shown inFIG. 1 ) so that aconveyor 60 operatively coupled with the sealer is properly positioned to transport the wound coil and sealed container from the combination coiler andsealer 10 to a heat shrink oven, as will be described hereinafter. Thesealer 40 may be provided with any suitable means for moving the sealer horizontally relative to thecoiler 20, including a plurality ofwheels 43, as shown herein. -
FIG. 3 schematically illustrates a length of thecable 50 being wound onto thecentral core 22 of thecoiler 20 as the central core is rotated by the drive means 23 in the counter-clockwise direction indicated byarrow 25 to form awound coil 55 of the cable. It should be noted that thecoil 55 may be wound in any desired manner or pattern. By way of example only, the feedingtube 26 may be configured to traverse the longitudinal length of thecentral core 22 in lateral back-and-forth movements at a constant rate of travel. Alternatively, the feedingtube 26 may be configured to traverse the longitudinal length of thecentral core 22 in back-and-forth lateral movements at a variable rate of travel. In the latter instance, thecoil 55 of thecable 50 may be formed in a non-cylindrical shape, for example in a generally spherical shape, or conversely, in an hourglass shape. In addition, the feedingtube 26 may be configured to oscillate relative to thecentral core 22. Alternatively, the central core may be configured to oscillate relative to the feedingtube 26. In either instance, thecoil 55 of thecable 50 may be wound in a predetermined pattern, for example in a series ofFIG. 8 configurations, as is well known in the art. -
FIG. 4 schematically illustrates thecoiler 20 cutting (i.e. severing) thecable 50 adjacent the feedingtube 26 of the coiler when thecoil 55 has a predetermined configuration. - For example, the
cable 50 may be cut once thecoil 55 has a desired longitudinal length along thecentral core 22 and a desired diameter about the central core. For a givencable 50, the predetermined configuration of thecoil 55 typically corresponds to a desired length of the cable delivered by the feedingtube 26 onto thecentral core 22 of thecoiler 20. Thecable 50 is cut by a conventional cutting means (not shown) in any suitable manner to produce thefree end 52 of the cable adjacent the feedingtube 26 and acut end 54 of the cable wound onto thecentral core 22 of thecoiler 20 to form thecoil 55 having the predetermined configuration with aninner diameter 56 and anouter diameter 58. Thecentral core 22 of thecoiler 20 is then opened to release thecoil 55 from the central core. As used herein, the term “opened” refers generically to any operation or mechanical means that permits thecoil 55 to be removed, detached, separated, or the like from thecentral core 22. By way of example only and without limitation, thecentral core 22 may be reduced in diameter concentrically and withdrawn from within thecoil 55 so that the coil can be moved in a desired direction under the influence of a mechanical force, or alternatively, will drop in a downward vertical direction under the influence of gravity, as described herein. -
FIG. 5 schematically illustrates thecoil 55 formed from the length ofwound cable 50 dropping under the influence of gravity in a generally downward vertical direction indicated by the single-headedvertical arrow 45. Thecoil 55 drops into thesealer portion 40 of the combination coiler andsealer 10 between a pair of sealingbars sealer 40 comprises at least ahorizontal sealing bar 42 and avertical sealing bar 44. If desired, mechanical force means may be provided for assisting thecoil 55 to drop from thecoiler 20 into thesealer 40 and/or to direct or guide the coil into the sealer between the sealing bars 42, 44. As shown, a partially-sealed and partially-openedcontainer 46 formed from the roll ofsheet material 41 is disposed within thesealer 40 in a position to receive thecoil 55, including thecut end 54 of thecable 50. Preferably,container 46 comprises a conventional plastic bag made of a heat-sealable and heat-shrinkable material having at least twopre-sealed sides 47 so that thecoil 55 ofcable 50 is retained, but not yet encased and sealed within a plastic bag. As thecoil 55 is dropping into thesealer 40, thecentral core 22 of thecoiler 20 is returned to its initial unopened configuration in preparation for winding another length of thecable 50 to form anotherwound coil 55 in the manner previously described. At the same time, the feedingtube 26 of thecoiler 20 is moved to a location adjacent thecentral core 22, as indicated by thecurved arrow 30. As previously mentioned, thefree end 52 of thecable 50 may be secured (e.g. clamped) to thecentral core 22 of thecoiler 20 in any suitable manner. -
FIG. 6 schematically illustrates thecoil 55 disposed within the partially-sealed and partially-openedplastic bag 46 in thesealer 40, and thecentral core 22 of thecoiler 20 being rotated by the drive means 23 in the counter-clockwise direction indicated bycurved arrow 25. Thecentral core 22 of thecoiler 20 is rotated by the drive means 23 in the counter-clockwise direction to wind another length of thecable 50 onto the central core to form anotherwound coil 55. As thenext coil 55 is being formed, the one or moreopen sides 48 remaining on theplastic bag 46 are sealed such that thecoil 55, including thefree end 54 of the length of thecable 50, is encased within the sealed bag. Theopen sides 48 of theplastic bag 46 may be sealed in any conventional and known manner, including for example without limitation, pressing and heat-sealing (e.g. thermoforming) the opposed edges of the open sides to thereby encase thecoil 55 within the sealed bag. -
FIG. 7 schematically illustrates the completely sealedbag 46 containing thewound coil 55 dropping in the generally vertical downward direction indicated by thearrow 65 onto aconveyor 60 having a movable conveyingsurface 62. As shown and described herein, thecoil 55 encased within the sealedbag 46 is dropped from thesealer 40 in a generally vertical downward direction onto the conveyingsurface 62 of theconveyor 60 under the influence of gravity. Alternatively, thecoil 55 andbag 46 may be dropped, assisted, directed and/or guided from thesealer 40 onto the conveyingsurface 62 under the influence of an external mechanical force in the manner previously described with reference to thecoiler 20 and thesealer 40. The conveyingsurface 62 of theconveyor 60 is oriented at an angle relative to the vertical downward direction indicated byarrow 65, and more particularly, is inclined so that thebag 46 containing thewound coil 55 is automatically aligned parallel to the conveying surface. More specifically, the sealedbag 46 containing thecoil 55 naturally tips downwardly (i.e. clockwise from the orientation shown) and over onto one side as the conveyingsurface 62 moves in the direction indicated by thearrow 75 inFIG. 8 . If desired, thecoil 55 encased within the sealed,plastic bag 46 may be moved by the conveyingsurface 62 of theconveyor 60 to an associated packing and shipping station to be packed into a reinforced container, for example a cardboard carton or a corrugated box, for shipment a customer or end user. Preferably, as illustrated schematically inFIG. 8 , the sealed,plastic bag 46 containing thewound coil 55 is first transported into aheat shrink oven 70 operable for heat-shrinking the heat-shrinkable material of the sealed, plastic bag around the coil. - The foregoing detailed description in conjunction with the accompanying drawing figures has described one or more exemplary embodiments of a system and method for coiling a length of an elongate, flexible component in the form of a coil, and for subsequently encasing the coil within a sealed container. In an exemplary embodiment, the system and method includes a combination coiler and sealer comprising a central core, a feeding tube for guiding a length of the flexible component onto the central core, and a drive means for rotating the central core to wind the length of the flexible component onto the central core and thereby form the coil. The wound coil is then released from the central core of the coiler and received within a partially-sealed and partially-opened container positioned beneath the coiler and disposed within the sealer. The container has at least two pre-sealed sides and the sealer is configured to seal each of the remaining one or more open sides to thereby encase the coil within the fully sealed container. The elongate, flexible component is preferably selected from the group consisting of cable, wire, tubing and the like. The container is preferably a plastic bag formed from a roll of heat-sealable and heat-shrinkable sheet material.
