Definitions

• the present invention concerns a procedure and an arrangement for winding flexible, elongated elements onto partial reels arranged in a row and wrapping these with a protecting film of elastic material.
• the invention also concerns a packaging with wrapped reels produced according to the procedure according to the invention.
• a core is attached to the rotating spool-head, where the core preferably includes a drum provided with a flange on which the cable is wound and possibly, but not necessarily, provided with a protective and unifying wrapping of plastic film.
• the assembly formed by this means is thereafter pulled off the spool-head in its entirety, i.e. accompanied by the core.
• the problem of withdrawing a pre-determined length of wound cable or reeled flexible element can, for example, arise in that the user may on one occasion wish to withdraw only a part of the element whose length differs significantly from the length of the element that is wound on one continuous reel and wrapped in plastic film.
• lines that are wound on spools the solution to this problem is already known through, for example, US 2 912 102. According to this document, which does in fact refer to fishing lines, the problem is solved in that a comparatively long line with no breaks is wound on several spools arranged following one another.
• spools are subsequently arranged in a row with a coinciding centre axis and are packaged so that they are connected by being provided with a wrapping of elastic transparent material, preferably plastic film, that by elastic shrinkage tightly wraps and fixes the said spools. and thereby even the line on each one of them, in position.
• the desired length of line in the form of a chosen number of spools can then be simply removed from the package in a conventional way by the wrapping being split peripherally at a suitable place and the line being cut, whereby the plastic film tightly wrapping the spools keeps the line remaining on the respective separated spool sections.
• the problem is that so far there have been no efficient and workable methods for winding a single elongated continuous flexible element onto several partial reels or segments arranged after one another in a row and then wrapping these with elastic film so that a predetermined length of the element in the form of a specified number of partial reels can be simply removed from the packaging without the removed partial segment/segments needing to be repackaged.
• One objective of the present invention is therefore to achieve a procedure that makes this possible and, more specifically, allows the production of core-free "multi-reels", i.e., a number of reels arranged after one another as segments and wrapped in an elastic film.
• a second objective of the invention is to achieve an arrangement for performing this procedure, and a third objective is to achieve a packaging of an elongated flexible element wound onto partial reels and wrapped with elastic film that is designed so that by means of a peripheral sectioning of the wrapping that is common to all of the reels, a pre-determined length of the element in the form of a specified number of partial reels can be simply removed from the packaging without the removed section/sections needing to be repackaged.
• the wrapping of elastic film on every partial reel can be further improved if the partial reel that is to be provided with a wrapping is at a distance from a reel that has been provided with a wrapping in a previous step so that this partial reel does not constitute a hinder for the wrapping sequence of the partial reel that is to be provided with a wrapping.

• fig. 8A - 81 illustrate the measures taken according to the invention when it is used to wind flexible elements onto partial reels and wrap these in a cover of elastic film
• fig. 9 shows a package of the partial reels produced with the procedure according to the invention.
• the reference number 1 designates the base mounting plate or frame of the arrangement according to the invention, on which a drum 2 is attached in an overhanging, cantilever manner for rotational movement so that when operated by a driving unit in the form of an electric motor (not shown) with gearing where the number of revolutions per minute can be adjusted, it can be brought to rotate at a chosen speed around an essentially horizontal axis.
• the speed of rotation of the drum 2 is registered, for example, by a pulse transducer attached to the axis of rotation and communicated to a control unit not shown in detail on the drawings.
• a control unit not shown in detail on the drawings.
• a feeding mechanism 4 is arranged that includes a number of rollers between which an elongated element designated 5 runs prior to it being wound onto drum 2. Since the feeding mechanism 4 synchronised with the speed of rotation of the drum 2 performs a continuous forwards and return movement parallel with the main axis of the drum, the element 5 passes through feeding mechanism and is applied onto the drum 2 with overlapping, evenly spaced turns along the length of the drum. Adjacent to the rotating drum 2, a unit 6 for wrapping the element 5 wound on the drum with elastic film 7, preferably in the form of plastic film, is arranged on one side of the drum.
• This unit 6 includes a rotating housing and a replaceable cylinder 8 equipped with a braking device and arranged to carry a roll of plastic film 9 that, as a consequence of the rotation of the drum and its passage over two cylinders 10, 10', allows the film to be continuously fed out from the roll and wrapped around the element 5 wound on the drum 2.
• the unit 6 is arranged to be moveable in an axial direction so that it can travel backwards and forwards in parallel with the main axis 3 of the drum 2.
• the cylinders in a per se known manner can be designed so that the film 7 is stretched in a sideways direction as it passes over the cylinders.
• the arrangement also includes an arm 11 housed so that it can be pivoted on the frame 1 via the axis of rotation 3 of the drum 2 and arranged to perform an oscillating movement about the drum 2 in a first direction by the interaction of a piston and cylinder device (not shown in the figure) between the arm 11 and the frame 1 , and a return movement in a second, opposite direction by a turning plate arranged on the pivoting axis 3 of the drum and a braking device acting on this, by means of which the arm 11, through fixed braking, is rapidly returned to its starting position by the drum (not shown in the figure).
• arm 11 supports a clamping device 12 that, when the arm is in its starting position as shown in fig. 1, is positioned between the two cylinders 10, 10 ' .
• This clamping device 12 which is not described in greater detail, is designed so that the elastic film 7 is always taken up by it.
• the said clamping device can in general be said to include a "claw" in the form of interacting arm parts of which one is housed so that it can be pivoted and its manoeuvrability affected by a piston and cylinder device (not shown in the figures).
• the task of arm 11 is to utilise the clamping device 12 to grip hold of the plastic film 7 and draw it out from the roll 9 and, by oscillating in the first direction about the drum 2, initially apply the said film to a reel wound onto the drum so that it attaches to it.
• the piston and cylinder device is deactivated and the braking device for the plate is activated so that the arm 11 , and thereby also the clamping device, accompanying the drum, rapidly return to their starting position whereby the remaining main part of the elastic film 7 is drawn out and applied to a reel of a wound element during the rotation of the drum.
• Drum 2 has a periphery or a surface circumference that is formed from a number of beams 13 that are essentially U-shaped and oriented with their open end facing inwards towards the centre of the drum 2.
• the beams 13 are equally distributed at preferably the same distance from one another around the circumference of the drum 2 and at preferably the same radial distance from the axis of rotation.
• the beams are arranged in a displaceable manner at the drum by a holding and guiding device 14 that consists of guide rails 15 extending radially outwards from a hub at one end of the drum 2 and, at the other end and as evident from fig. 1 , a linear adjusting mechanism 16 that extends between the free ends of two opposing beams.
• a travelling screw 17 arranged at the free end of the rails 15 that acts on a displaceable housed body 18 to which the end of the beam is attached by welding.
• the adjusting mechanism 16 that acts between the free ends of the beams 13 includes a manoeuvring handle 19 that, by means of turning a gearing not described in greater detail, causes the beams to move in a radial direction towards or away from one another.
• a manoeuvring handle 19 that, by means of turning a gearing not described in greater detail, causes the beams to move in a radial direction towards or away from one another.
• the shape of the drum can quickly be changed so that a slimmer form is obtained towards its free end.
• a piston and cylinder device 20 is arranged at the adjusting mechanism 16 and is active between the said gearing and the free ends of the beams, as is best evident from fig. 1.
• a convex sheeted element 21 is, as shown in fig. 7, fixed to the end section of beam 13 and turned to face outwards from drum 2 and with dimensions chosen so that it extends significantly out from the edges of the beam.
• guiding devices 22, 22 ' In the space between the beams 13 that form the drum 2 there are a number of guiding devices 22, 22 ' whose task during the sequence of winding events is to guide the flexible element 5 so that it remains within an axially limited area on the drum.
• guiding devices 22, 22 ' are arranged in a first and second arrangement or ring and are distributed uniformly along the circumference of the drum where each and every one is arranged to selectively and synchronously with the rotation of the drum, move in a continuous cyclical track that is primarily oriented parallel with the axis of rotation 3 of the drum 2.
• the arrangements of guiding devices 22, 22' are arranged on the drum so that when in their respective active positions they extend above the peripheral surface of the drum 2 and, in this position, form two rings facing outwards from the drum and located in two radial planes separated from one another along the drum.
• the guiding devices 22 in one of the rings move in common so that they can alternately exchange places with the guiding devices 22 ' in the other ring by momentarily moving along the outside of the drum at the same time as the guiding devices 22 in the other ring are withdrawn into the drum 2 and move inside it.
• a holding and guiding device 23 arranged at the drum that, in the described embodiment, consists of a number of comparatively elongated elements in the form of U-shaped guide rails 24 that are uniformly distributed along the circumference of the drum 2 in the spaces between the beams 13 that define the peripheral surface of the drum.
• the guiding rails 24 are arranged parallel with the main axis 3 of the drum and each one supports its respective said guiding device 22, 22 ' that, via a sliding body 25, are guided by being displaced axially in guide rail 24.
• the first and second rings of guiding devices 22, 22' are further arranged so that they can independently of one another but in common in each ring, be displaced radially in relation to the drum 2, in other words, in and out of the drum.
• This movement of the guiding devices 22, 22 ' is achieved by the guide rails 24 being freely supported by arms 26 that extend radially from the hub of the drum 2 and that are evenly distributed along its circumference, and that holding and guiding devices 27 are active between the arms 26 and the guide rails 24 so that these can move along the arms. Because of the relatively large bending momentum that occurs at the attachment point between each guide rail 24 and arm 26, there is a requirement that only very small forces of friction occur between the relative movements of these parts.
• every similar holding and guiding device 27 is preferably designed as a twin-axle trolley 28 with two rollers 29 arranged on each axle 30, and whose rollers have a diameter greater than the largest width of the body of the trolley.
• Each arm 26 is in this case essentially designed as a U-shaped guide rail 31 in which the trolley 28 is arranged to move and where the guide rail's rib and flange sections form, together with the trolley 28, the interacting guide and running surfaces.
• the guiding devices 22, 22 ' that support the ends of the guide rails 24 are welded to the running trolley 28 and can move along the U-shaped rail's 31 longitudinal opening.
• the manoeuvring of the running trolley 28 along the U-shaped guide rail 31 and the manoeuvring of the sliding body 25 along guide rail 24 can take place independently of one another and in this case by means of pneumatically activated piston and cylinder 32 and 33 devices located in the said guide rails where the pressurised medium is transferred from a pressurised medium source to the said manoeuvring device 32, 33 via a per se known swivel function arranged at the hub of the drum 2.
• the procedure according to the invention is explained in the sequence of drawings in fig. 8 A - 81 with regard to the winding of elongated flexible elements onto partial reels and wrapping these partial reels- with a covering of elastic film.
• the guiding devices 22, 22' are arranged in the form of a first and a second ring, 34 and 35 respectively, with three guiding devices included in each one of the said rings and arranged to move in common and simultaneously in a continuous cyclical path, i.e. both radially and axially in relation to the drum as shown in fig. 8C.
• the guiding devices 22, 22 ' in each ring 34, 35 are evenly distributed along the circumference of the drum 2 and are found within respective radial planes that, in the guiding device's active position, are found at their greatest distance from one another along the drum, as is shown in fig. 8B.
• the guiding device 22 of the first ring 34 is set-up at an angle of 45 degrees to the guiding device in the second ring's 35 guiding device 22' , which is evident if fig. 8A is studied more closely.
• Step 1 shows the guiding devices 22, 22' in their respective active positions so that a flexible element fed through feeding mechanism 4 is wound onto a first reel on the first ring 34 by guiding device 22, i.e., the ring seen on the left in the figure.
• the second ring 35 of guiding device 22' i.e., the ring seen on the right in the figure, is not used and rotates freely in this position.
• Step 2 (fig.
• FIG. 8E shows a position where guiding device 22 of the first ring 34 has exchanged places with the guiding device 22 ' of the second ring 35 after the first reel on the guiding device of the first ring has been completed.
• the said exchange of positions has in this case taken place earlier by the second ring's 35 guiding device 22' being withdrawn into the drum 2 and moving within the drum 2 to the starting position for the guiding device 22 of the first ring 34, at the same time as the guiding device for the first ring, moving along the outside of the drum, has been transferred to the starting point for the guiding device of the second ring.
• step 3 the unit 6 for wrapping the wound element has been activated to wrap the finished reel with elastic film at the same time as a second reel is being wound on the ring guiding device seen on the left in the figure.
• the film is stretched so that it breaks off.
• Step 4 shows a position where the first and second guiding devices 34 and 35 respectively have once more exchanged places just like in step 2 and where the reel wrapped earlier has simply been pushed or knocked outwards towards the free end of the drum 2 by the second, following reel.
• Step 5 shows how the second reel is being provided with a wrapping film, while the first reel is located furthest out on the drum and a new reel is being wound by the guiding device of the inner ring.
• the guiding device for the outer ring moves a short distance in towards the hub so that the finished reel pushed out on the drum 2 does not hamper the wrapping process.
• step 6 the second reel provided with a wrapping of film is moved to lie against the first reel so that both of these can be provided with a wrapping of film.
• the whole process proceeds without interruption when the winding and wrapping with film can take place directly adjacent to the equipment that produces the flexible element, e.g. in cases when the equipment constitutes plastic injection equipment and the flexible element constitutes a plastic tube.
• the drum does not accelerate or brake during the winding and wrapping processes, which offers the advantage that the speed of production of the device according to the invention can be synchronised with the speed of the equipment in the preceding manufacturing step.
• the flexible element is not cut until a pre- determined number of partial reels or segments has been obtained. The final segment is, however, not provided with a film but is simply left on the drum.
