  • the lower limbs each include a notch such as notch 23 for receiving the shaft of a roll 24 of stock material which in the embodiment shown is single-ply kraft paper.
  • the upper limbs of the C-shaped members each include an upwardly extending ear 26.
  • a pair of vertically spaced rods 27, 28 extend generally horizontally between the resulting pair of ears 26, such that there is a gap between the rods 27, 28.
  • stock material is unwound from the roll 24 and fed from the left hand side of the apparatus as shown in Figure 1 through the gap between the rods 27, 28. From there, the paper is fed via an inlet opening in the left hand end of housing 13 into the dunnage convertor contained therein. This results in continuous feeding of the stock material until the roll 24 is used up, at which point a fresh roll 24 may be loaded onto the lower limbs of the C-shaped members and fed as aforesaid.
  • the dunnage convertor includes a post-cutting constraining assembly 86, which is in the form of a rectangular-section tube.
  • the post-cutting constraining assembly extends horizontally, and it protrudes through an aperture in the right hand end of housing 13.
  • the post-cutting constraining assembly 86 is cranked upwardly to terminate in an outlet 86a the opening of which is at the same level as the surface 14 of packing table 10.
  • the dunnage convertor includes various components for producing low-density cushioning material (dunnage) from the stock material; and a cutter for cutting discrete lengths of the formed dunnage.
  • Suitable electrical controls 30 are mounted on a power supply housing 31 in order to provide control over the operation of the dunnage convertor 100.
  • the controls would additionally include e.g. a foot pedal connected to the control circuitry of the dunnage convertor, so that the operator can produce cushioning dunnage at will without the need for intervention by hand.

  • the sub-chassis comprises upper and lower pairs of horizontally spaced, extruded members 40, 41; 42, 43.
  • the upper pair of members 40, 41 are mterconnected by a horizontal brace 48 at the ends of the members 40, 41 remote from housing 13; and the lower members 42, 43 are interconnected by a further bracing member 49.
  • the undersides of the free ends of the members 42, 43 include screw- adjustable feet, such as feet 12 previously referred to, for assisting in levelling of the apparatus 10.
  • screw- adjustable feet such as feet 12 previously referred to
  • acmator 46 The spacings of the members 40, 41 and 42, 43 are such that a square-section, linear electric acmator 46 may be fixedly secured therein.
  • the upper end of acmator 46 includes an acmator rod 46a that is secured to the underside of work surface 44 and on operation of the appropriate controls secured on control box 45 the work surface 44 may be raised or lowered as desired.
  • further work surface 44 includes a recess 50 that is shaped to permit the work surface 44 to rise and fall without fouling on the post- cutting constraining assembly outlet 86a.
  • the upper end of acmator rod 46a terminates in a large area element, so that in the embodiment shown the entire weight of the further surface 44 is supported and guided by actuator 46 and there is no need for additional guide members.
  • such members could if desired be incorporated, for example extending vertically at the corners of housing 13 at the positions 52 and 53 shown in Figure 2.
  • the packing table of the invention may simply be considered as a large area packing table having an outlet 86a for low density dunnage material approximately two thirds of the way along its length. The locating of the outlet 86a in the this position permits the production of dunnage material for use at either end of the packing table.
  • the apparatus of the invention may be used in a number of ways in addition to the manner described above.
  • an operator who has to produce a large number of packs of a generally small size and occasional packs of a lajrge size could operate the controls at control panel 45 to lower the further work surface 44 to a suitable height for the large packs, and then simply leave the further work surface 44 in that position ready for the occasions when it is necessary to produce large packs.
  • the operator would then spend the majority of his or her time working at the work surface 14, and would only turn to further work surface 44 when it proves necessary to produce large packs.
  • an operator could work by repeatedly altering the height of further work surface 44 relative to work surface 14, as would be required if the numbers of large and small packs to be created were approximately equal.
  • the embodiment shown in Figure 1 includes an optional superstructure 60 at the rear of housing 13.
  • Superstructure 60 extends upwardly of work surface 14 and terminates in a shelf 61.
  • Shelf 61 may optionally be sub-divided by means e.g. of dividers such as hoops 62 shown in Figure 1. A greater number of hoops 62 than those shown can be provided if desired.
  • Figure 3 generally illustrates the internal conversion assembles of a preferred cushioning conversion machine such as that shown in U.S. Patent No. 5,123,889 to which reference may be had for further details.
  • the convertor 100 includes a forming assembly 120, a feed gear assembly 122, a cutting assembly 124, and the post-cutting constraining assembly 86. The general operation of these assemblies is described in detail in U.S. Patent No. 5,123,889.
  • Access to the convertor 100 is achieved in the embodiment shown by virtue of work surface 14 being hinged at break line 14c, whereby work surface 14 is divided into two portions 14a, 14b. It will be evident that work surface 14b can be pivoted about break line 14c to provide access to cushioning dunnage convertor 100.
  • packing table of the invention may be embodied in numerous ways, and need not be restricted to the precise form shown in the drawings. Furthermore, various materials and finishes may be used for or applied to the components of the table.

Abstract

Si le principe des tables de conditionnement comportant des distributeurs de produit d'emballage est connu, ces tables n'en présentent pas moins des inconvénients lorsqu'il faut confectionner des paquets volumineux puisque, jusqu'à présent, il ne s'est agi que de tables à hauteur fixe. L'invention porte sur une table de conditionnement (10) comportant et une surface de travail à hauteur fixe (14) et une surface de travail à hauteurs variables (44), la hauteur de cette dernière étant réglée au moyen d'un vérin linéaire (46) commandé par des commutateurs appropriés (45). Dans certains modes de réalisation préférés de cette invention figure un dispositif de conversion en matelassure protectrice d'emballage (100), faisant partie intégrante de la table de conditionnement (10), de telle sorte que l'orifice de sortie de matelassure (86a) du dispositif de conversion (100) débouche entre les surfaces à hauteur fixe et à hauteurs variables de la table de conditionnement.
