Definitions

  • the subject of the present invention is a strapping trolley.
  • the term "strap” generally refers to a band of variable thickness or height used to pack, for example, sections, tubes, flat sheeting or the like or for binding other objects such as packing cases.
  • the strap may be of a variety of different materials, and in particular metal.
  • the prior art includes devices, sometimes portable, in which the reel of continuously wound strapping is housed.
  • the band or strap is manually unwound, rewound around the objects to be packed up, tightened by means of a suitable device also known as a strapper, and cut by the same device.
  • a suitable device also known as a strapper
  • the two ends of the strap are usually joined together by means of a seal.
  • Figure 1 is a front end view of a strapping trolley according to the present invention.
  • Figure 2 is a front end view of the strapping trolley of Figure 1;
  • Figure 3 is a plan view of the trolley of Figures 1 and 2 in which some parts are omitted for clarity;
  • Figure 4 is a partly sectioned side view of the trolley of Figure 1 taken on the line VI-VI;
  • Figure 5 is an enlarged view of detail V from Figure 4.
  • the number 10 is a general reference for a strapping trolley.
  • horizontal refers to a plane or direction parallel to a surface P on which the trolley 10 is standing
  • vertical refers to a plane or direction perpendicular to the surface P on which the trolley is standing.
  • the strapping trolley 10 comprises a supporting element 12.
  • This supporting element may for example comprise tubular parts 14 with bearer plates 16 fixed to them, preferably parallel to the surface P on which the trolley is standing.
  • the trolley 10 comprises at least two fences 20 mounted on the supporting element 12 and defining a space 22 for receiving at least one reel of strapping 24 which is formed around an axis 24a.
  • the fences 20 define, for each space, parallel faces 23 arranged preferably in a vertical direction.
  • a fence 20 is made of tubing or a hollow structure.
  • the fences 20 are mounted on the supporting element 12, extending transversely with respect to the latter and in an essentially vertical direction.
  • At least one of the fences is securely fixed or welded to the supporting element 12, particularly to uprights 28 that extend at right angles to the supporting element 12.
  • At least one of the fences 20 is mounted on the supporting structure 12 in such a way as to be movable with respect to an adjacent fence in order to vary the transverse dimension of the space 22 defined between these two fences.
  • the example shown in the figures has the uprights 28 and four fences whose position in a direction parallel to the axis 24a of the reel of strapping can be varied.
  • the number 30 denotes means for the relative locking of the fences so as to define a given transverse dimension of each space 22.
  • the locking means 30 comprise at least one screw or threaded bar 32 inserted transversely through the fences 20 and at least one spacer 34 having a length equal to the predetermined transverse dimension of the space and interposed between two adjacent fences.
  • each screw 32 has a head 32a and a threaded end 32b for a nut 36.
  • the at least one spacer 34 is coaxially mounted on a respective screw 32.
  • the spacers are mounted coaxially on the four upper screws at the sides of the reel of strapping 24.
  • the spacers 34 perform the additional function of keeping the reel of strapping in its space, preventing it from moving in a transverse direction with respect to its axis.
  • the spacers 34 comprise a hollow cylindrical element of larger size than the corresponding threaded bar.
  • the trolley 10 comprises at least one rolling-contact bearing element 38 interposed between two adjacent fences 20.
  • the rolling-contact bearing element 38 is advantageously mounted coaxially on one of the contact screws.
  • each space there are two rolling-contact bearing elements 38, each mounted coaxially on one of the six screws 32 and in particular on the lower screws relative to the reel of strapping 34.
  • the two rolling-contact bearing elements 38 are preferably arranged symmetrically with respect to an axis of symmetry a-a of the trolley 10.
  • each rolling-contact bearing element 38 in a space comprises two ball bearings fitted onto the same screw 32.
  • the two bearings may themselves be separated by an additional spacer 39.
  • the supporting element 12 comprises at least one box 40, for example for containing seals. In the example illustrated there are three boxes for seals or other devices such as the strapper.
  • the supporting element 12 extends to define a supporting surface 42 for at least one compressor 44.
  • the supporting element 12, and in particular the upright 28, preferably comprises quick-release attachments 46 for the connection to the compressor of equipment capable of carrying out the operation, e.g. the so-called strapper.
  • the trolley in question has been made ready to support three reels of strapping 24 of differing widths (for example 16 mm, 32 mm and 19 mm).
  • the nuts 36 must be undone, the spacers 34 and if relevant the additional spacers 39 must be replaced, and the fences 20 must be locked again to the supporting element 12 or to the uprights 28.
  • the structure of the trolley designed as herein described also offers great versatility in respect of the number of reels of strapping that can be housed in one trolley.
  • the strapping trolley according to the invention advantageously has a modular structure that adapts to both the width and the number of reels of strapping to be held.
  • the compressor is completely integrated into the actual structure of the trolley, achieving an overall synergistic effect for example due to the fact that the quick-release attachments allowing connection to the compressor of tools for carrying out the operation are integrated into the structure of the trolley, thereby reducing its bulk.
  • the strapping trolley according to the invention makes it possible to achieve other advantages, such as greater tidiness in the premises in which the operation is being carried out and consequently greater safety for the operators involved.
  • Another advantage of the strapping trolley according to the invention is its unusually simple structure, which means that it can be produced at a very moderate cost.
  • the strapping trolley may be fitted with only two fences with an adjustable separation to accommodate a single reel of strapping but of variable width. If required, both fences can be movable to vary the thickness of the space.
  • the number and/or shape of the fences, of the threaded bars, the spacers and of the rolling-contact bearing elements may vary.
  • the rolling-contact bearing elements may be produced in other forms.
  • the compressor integrated into the supporting element need not be present. Also, there could be an embodiment of the strapping trolley in which the fences are fixed and not adjustable and the supporting element is extended to support and incorporate a compressor.
  • the embodiment of the means for locking the fences to the supporting element or to uprights connected to this can also vary.
  • lateral clamps, or spring-action rather than threaded elements, or the like, could be used.
