DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a tool for detachable assembly on a drum of disposable type to form a rotatable unit to be placed in journalling equipment for rotation of the unit, said drum comprising a cylindrical sleeve and two end pieces which are secured to the sleeve to prevent them from slipping axially towards each other, the drum being designed to carry a coil of a continuous flexible object, comprising cable, line, wire, wire cable, rope, cord, ribbon, chain or the like, said tool comprising two support and bearing elements, each having a hub-forming sleeve, a plurality of support arms rigidly joined to the hub and forming right angle or substantially right angle with the central axis of the hub, and a concentric support member for supporting and centering the drum by means of internal engagement with both end portion of the sleeve; and also a connecting member comprising a shaft arranged to extend through the sleeve and said hubs, and anchoring means for anchoring the support and bearing elements to said shaft while at the same time securing the sleeve against axial displacement in relation to the shaft. The invention also relates to a drum of disposable type for assembly with a tool of the type described, and the combination of drum and tool of the type described.
SE-468 129 (9101042-1) describes a new method of manufacturing, packing, distributing and using a coil of a continuous flexible object, such as a cable, through which method the conventional, returnable wooden drums and the many drawbacks entailed with their use are eliminated, and valuable advantages and plus effects are achieved throughout the chain of handling from producing the coil to uncoiling the cable, etc. on site and even, where relevant, to recovery of a scrap line. Said patent also describes a tool for use with this method, which tool has two support wheels designed to clamp between them a sleeve for said coil and designed to be in contact with the ground when the tool is to be fitted onto an empty sleeve and on a finished parcel of the coil and after the coil has been produced. In order to give the coil lateral protection the sleeve is provided with two protective rings having smaller diameter than said support wheels so that they do not come into contact with the ground.
The object of the present invention is to produce a tool for use in the described manner, which is simpler to handle and simpler to assemble to and dismantle from a sleeve, as well as having low weight and thus being cheaper to manufacture.
It is also an object of the invention to produce a drum of disposable type which is simple to manufacture and which enables the use of a tool to be fitted to the drum to form a rotatable unit that is simpler to manufacture and simpler and lighter to use.
The tool according to the invention is characterized in that the support arms are arranged to abut in supporting manner against the end pieces and have free ends located radially inside the outer circular edge of the end pieces so that the support arms are not in contact with the ground when said unit is resting on the ground by means of the end pieces of the drum.
The invention is described in more detail in the following with reference to the drawings.
FIG. 1 shows in perspective a first tool which is particularly suitable for use when coiling a cable, etc.
FIG. 2 shows parts of a drum to which the tool in FIG. 1 shall be connected.
FIG. 3 shows the finished drum.
FIG. 4 illustrates assembly of the tool on the drum.
FIGS. 5 and 6 show a longitudinal section through a tensioning device for the tool according to FIG. 1, in inactive and active position, respectively.
FIG. 7 is an end view of the drum and the tool before they have been locked together.
FIGS. 8, 9 and 10 show different steps in the assembly process with the aid of the tensioning device shown in FIG. 5.
FIG. 11 is a view in perspective of the rotatable unit ready for placing in a coiling equipment.
FIG. 12 shows the unit according to FIG. 11 with a finished coil of cable, etc.
FIG. 13 shows the unit with
