DESCRIPTION:
BRIEF SUMMARY
This invention relates to a method of packing a rope into a container in such a manner as to permit easy extraction of the rope therefrom, in which method the rope is withdrawn from a supply reel and led down into the container to be coiled therein with the coil centre situated between the centre line and periphery of the container, while the container is rotated and a simultaneous relative axial movement is effected between a winding head and the container.
Survival equipments comprise a container with a rope which is intended for extraction by means of a rocket. For this reason it is of extreme importance that the rope runs out with the least possible resistance. This naturally places great demands on the packing of the rope, which at present is made entirely by hand and thus of course implies high packing costs. The reason why packing is carried out by hand simply is that hitherto no machine has been available, which is capable of performing this work with the desired reliability.
The object of the present invention is to pack such a rope in a novel manner so that all safety requirements are satisfied at the same time as the packing of the rope can be carried out mechanically. This object is attained in that the rope is withdrawn from the supply reel by means of the rotating winding head and discharged from the head for coiling and is rotated or twisted about its longitudinal axis on its way down into the container.
The invention also relates to a machine for packing a rope of this kind, said machine being characterised in that it comprises a frame with a shaft fixed at its upper end and extending a predetermined distance vertically downward, a supporting device rotatably mounted on the shaft and having a rope reel rotatably mounted thereon, a support means for the container for supporting it such that its centre line extends parallel to but laterally spaced from the fixed shaft, whereby said shaft projects into the container with its axis situated in the space between the centre line and periphery of the container, a rotary winding head on the free end of the fixed shaft projecting into the container, said winding head being adapted, upon rotation, to withdraw the rope from the rope reel during the rotation of the reel supporting device and to coil the rope with the coil centre situated between the centre line and periphery of the container, and means for rotating the rope reel supporting device, the winding head and the support means with the container and simultaneously axially moving the support means vertically downward.
The invention will be more fully described below with reference to the accompanying drawings in which:
FIG. 1 in elevation shows an embodiment of the invention; and
FIGS. 2 and 3 on a larger scale show a winding head in section and from below.
According to FIG. 1 a machine according to the invention has a frame 10 which is fixed to a bottom plate 11. At the top the frame has a transverse beam 12 in the centre of which a vertical shaft 13 is secured by means of a fastening device 14. The shaft 13 extends vertically downward and a supporting device generally designated 15 is rotatably mounted at a distance from the transverse beam 12. The supporting device 15 has a drive pulley 16 which is coaxial with the shaft 13 and about which a V-belt 17 is passed. The V-belt 17 is driven by a drive pulley 18. Secured to the supporting device 15 is a holder 19 for rotary accommodation of a rope supply reel 20 onto which is wound a rope 21. The supporting device 15 at the underside of the V-belt pulley 16 has a fastening 22 with which a tubular sleeve 23 is rigidly connected via flange means. The sleeve 23 extends about the shaft 13 coaxially therewith down to the lower end of the shaft 13. Further, a tube 24 is connected to the underside of the supporting device 15 and the upper end of the tube opens opposite the longitudinal centre of the reel 20 mounted on the supporting device 15 while the lower end of the tube 24 opens adjacent the outer periphery of the sleeve 23. The rope 21 is intended to
