Description

Packaging device and manufacturing method thereof

The present invention relates to a packaging device for continuous flexible elements such as cables, strings, ropes, steel cables, wires, hoses, etc. in a protective closed case suitable for storage and transportation Wound into rolls.

Swedish patent SE-B-469228 discloses a method of encapsulating, for example, electrical cables in coil form in an encapsulating device from which they can be removed. However, the pulled out cable etc. will take on a helical persistent shape like a helix. This is a significant disadvantage, to overcome which it is necessary to turn the packaging device to thereby compensate for the helical shape.

Swedish patent SE-B-469228 also discloses an encapsulation device which protects eg cables during their storage and handling. The cable is wound into an upright cylinder and pulled out as a coil, so that when the cable is pulled out of the cylinder, it makes one revolution for each revolution of the cable, that is, the cable will Self-rotation occurs, which is what the present invention addresses, ie so that when the cable is pulled out of the enclosure it will be straight.

Clearly, there is a need for means to address this problem.

British patent GB-A-2,143,870 relates to a winding system in which the wire is wound on a reel which can then be unwound from it. Using a non-wire reel, the wire is unwound from the outside with the aid of an auxiliary device. This also allows the delivery opening to be unrestricted and it will cover the entire chevron portion of the packaged device.

To this end, a special rotary cable feeding device (45) as described on page 2, lines 27-38 must be used to feed the cable (12) from the cable drum (15). There is no mention here about the encapsulation of the wire and thus no axial discharge through the discharge opening on one side of the encapsulation device.

US-A-1,431,352 relates to a packaging device that allows a short or a long length of catheter to be pulled through an orifice without breaking the packaging device. This packaging does not disclose any pre-shaping of the catheter, but only describes a packaging from which the catheter etc. can be pulled repeatedly without damaging its contents.

US-A-3,135,380 relates to a support for a packaged device, which allows the packaged device to be positioned obliquely. This is not essential to the invention, even though it can be seen as an advantage when the contents of the packaging device start to reach the end and the weight of the packaging device is small. By tilting the packaging device backwards, it will be more difficult to "drop" the wire, conduit, etc. forward as it is pulled.

Swedish patent SE-A-8404780-2 discloses a device for moving a wire coil to another coil in order to exchange inner and outer ends or to cut a large coil into smaller coils. With this arrangement, the wire cannot be pulled straight unless the wire is turned or twisted.

Therefore, the main object of the present invention is to solve the above-mentioned problems with a simple and well-functioning device.

The above object is achieved by the packaging device of the present invention, the basic feature of the packaging device is that the flexible member is pre-wound and accommodated in a housing, and the front side of the housing is provided with a a centered exit for the shaped flexure, and the central exit is formed by an aperture through the housing through which the flexure can be pulled out of the housing without The reel-shaped winding roll is rotated.

The invention also relates to a method of manufacturing packaging means for continuous flexible elements such as cables, strings, ropes, copper cables, wires, hoses, etc. in a protective container suitable for storage and transport. The closed casing is wound into rolls.

Another object of the present invention is therefore to produce a suitable packaging device.

Said other object is achieved by the method of the invention, which method is essentially characterized in that by preforming said flexible element, i.e. by relative movement between a bobbin and a winding device for said flexible element Winding the flexure so that the pre-wound spool-shaped flexure moves into a housing where it can be closed and one end telescopically passed through a delivery port centrally located on the front side of the housing ; and the central delivery opening is formed by an aperture through the housing, by means of which delivery opening the flexible member can be pulled out of the housing without rotating the wound spool-shaped winding roll And will not make the flexible member form a spiral.

It will be apparent that the continuous flexible member wound into a roll is formed by pre-winding and then moved into a housing which has a central delivery opening on its front side. In this way, the flexible member is arranged such that it can be pulled out of the housing without any rotation of the spool-shaped winding and thus without any helical formation of the flexible member. This is a significant advantage currently available.

Thus, the main feature of the present invention is that the flexible cable or the like is pre-wound to be housed in a housing provided with a delivery port on its front side.

As a result, no additional devices are required at the point of pulling the cable out of the forming reel, since the cable can be pulled out without turning it upside down, and due to its pre-forming during the insertion of the cable into the encapsulating device, The cable is straight.

According to the invention, the cable can be pulled directly from the inner end of the coil without any additional means. This is possible on the basis of the special construction of the pre-forming and packaging device of the cable when it is loaded. The cable can be pulled out without flipping or twisting. The cable is straight due to its pre-shaping when it is loaded into the enclosure.

The invention is described below by means of preferred embodiments with reference to the accompanying drawings, in which:

Fig. 1 is the oblique front view of the packaging device of the present invention wherein the cable is in the delivery position from the closed housing;

Figure 2 shows the packaging device seen from the rear, again with the cable in the delivery position;

Figure 3 shows an embodiment of the delivery port of the packaged device, and

Figure 4 is a schematic illustration of the method used to wind the cable onto a spool to form a spool-shaped coil.

The flexible member 2 is pre-wound and placed in the packaging device 1 of the present invention. The packaging device is used to accommodate the continuous flexible member 2 wound into rolls such as cables, strings, ropes, steel cables, thin wires, and conduits. The finished coil is packaged in a protective enclosure 3 suitable for storage and transport of the flexible member 2. The flexible element 2 is wound on a bobbin 5 by means of a special winding device 4, during the preforming of the flexible element, the bobbin 5 and the winding device 4 are rotated relative to each other in the desired rotational directions 6 and 7, respectively.

The pre-wound flexible element 2 is freely accommodated in a rigid housing 3 which preferably has on its front side 9 a central outlet in the form of a round hole for the wound flexible element 2 8.

The housing is preferably formed by a cardboard box 3 which is square in shape and provided with suitable handle means 10 at its top 11 .

Furthermore, the central delivery opening 8 of the housing 3 is formed by a hole completely penetrating the housing 3 and its front side 9 .

It is also possible to manufacture the housing from a flexible material, such as plastic, in particular shrinking plastic, and to form a central delivery opening in this housing as described above for the embodiment of the rigid housing.

Preferably, the delivery port 8 can be configured to be easy to expand gradually, so as to facilitate delivery of the flexible component 2 when the flexible component 2 is pulled out through the opening 8 . Thus, the housing 3 has on its front side 9 a number of annular sections 12, 12A... which can be torn successively from the inside around said delivery opening 8, which is preferably designed as a circular periphery. Preferably, said tear-away portions 12, 12A... are formed by a plurality of curved apertures 13 passing through one wall of the casing, and are provided with a plurality of openings 15 from the outer periphery 15 of the casing 3 across the apertures 13. Straight orifice 14 for easy disconnection. Thus, the diameter of the delivery opening 8 can be increased as required by tearing apart the housing wall portions 12 , 12A one after another.

In order to stand the packaging device 1 upright, a support 16 on the housing 3 is provided. The upright support 16 may be formed by a folded element 17 on the rear side 3A of the housing 3, and the bottom edge 18 of the support 16 is inclined relative to the bottom edge 19 of the housing 3, so as to tilt the packaging device 1, by This facilitates feeding the flexible part 2 forward 20 , which can be pulled out in the pull-out direction 21 .

After winding the flexible element 2 into a roll according to the prior art by winding the flexible element 2 on an inner spool 5, which preferably has a cylindrical shape, the formed reel-shaped winding roll is moved into the cardboard-shaped housing 3 .

The free end 2A of the flexure can be pulled out through the central delivery opening 8 of said housing 3 without forming the otherwise easy to form helix, which is the problem being investigated for cables that can be wound into rolls . That is: when the cable is pulled out a straight cable is now obtained without any tangled loops.

The flexible element 2 is wound, preferably by turning the winding device 4 in the desired winding direction 6, by means of which the flexible element 2 is fed to a spool 5 and wound thereon according to the prior art. Thus, the flexible element 2 extends axially 23 relative to the bobbin 5 before it is fed tangentially 24 to the bobbin 5 .

The flexible member 2 may be accommodated on a large spool 25 supported by a spool support 26 for feeding to the forming winding device 4 prior to winding. After the member 2 has been wound into a shaped spool-shaped coil 27, it is enclosed in the above-mentioned housing 3, which is a rectangular housing and is provided with an orifice 8 on one side 9 and on the opposite side Upright supports 16 are provided.

The invention is not limited to the embodiments described above and shown in the drawings, but changes can be made within the scope of the claims without departing from the inventive concept.
