Description

_ 1 _

  The subject of the invention is a device for conditioning

  length articles delivered in rolls and, more especially, flexible conveyor belts for

  industrial conveyors of goods or materials.

  The long conveyor belts delivered in rolled form give rolls often 1.5 to 3 m in diameter and weighing in the order of 3 to 10 tons. For

  this is usually done with large wooden drums

  taking a cylindrical core and two lateral cheeks circulating

  res. These drums do not give satisfaction for several reasons. First, they are expensive and difficult to recover when they are shipped away from the band production plants. They are difficult to load on trucks or wagons

  o They must be carefully wedged. Their maritime transport

  time is often penalized because they are not super-

  sands and do not lend themselves to optimum occupation of the volume of ship holds. On soft ground the side cheeks sink and can allow the reels to tilt or deform, thus hindering the subsequent unwinding of the

gang.

  Another known method of expedition is to secure the band, which is wound on a core, on a simple pallet provided with wedges or a cradle. The system is less expensive, more stable on the ground and can be handled with standard forklift trucks but can not be stacked. On the other hand, one and the other of these systems do not lend themselves well to the operations of winding and unwinding of the band which require, both in the manufacturing plant and on the receiving site, the use of apparatus special reels

  or unwinders to receive and support the kernel of

  roller bearing, as well as the use of large lifting means, such as cranes or lifting bridges, for

  allow the assembly or disassembly of the roller on these

  same. All these materials are expensive, they are not always immediately available especially on the places of reception and use of the bands, which increases the costs and time of putting into service of the bands, with moreover

  risks of false maneuvers and deterioration of tapes.

  The invention aims to avoid these various disadvantages and to offer a cheaper device, easier to handle,

  likely to benefit from higher shipping rates

  tageux and which, in addition possibly allows to carry out conveniently the winding of the bands in the factories of manufacture and especially their unwinding on building sites

  receiving even few equipment handling equipment.

  To this end, the invention relates to a device for con-

  packaging large articles to be delivered in rolls and more especially flexible conveyor belts, characterized in that it comprises: - a rigid bridge comprising two spaced apart lateral supports integral with their lower part of a horizontal frame and each having their own upper part an opening bearing for receiving and stalling the end bearing surfaces of the winding core of the roller, - a horizontal pallet on which the frame is fixed

  easel type including longitudinal members that are per-

  pendicular to the vertical plane of the roller axis and raised from the ground to provide a forklift of a

  forklift, at least laterally in the direction

goes to the axis of the roll.

  Thanks to this bridge and pallet combination, the assembly formed with the roller on its core can be easily manned by means of a simple common type forklift generally available both in the factory and on the shipping sites and on the building sites. reception or the tape must be used. In addition, simply by loosening the bearings receiving the bearings of the winding core, it can be allowed to rotate as well to proceed with the winding of the tape to be shipped as to unroll it to put it on the installation of the conveyor having to use it and this without the need to resort to special unwinding devices, nor to the medium

they require.

  More advantageously still, the pallet constituting the base of the device is arranged so as to flush or overflow a little around the frame of the bridge so as to create itself the bottom of a packing box enclosing the

  roll, this box being built on the pallet.

  -3- This box of packing ensures the protection of the roll during the expedition and constitutes a stackable set that can benefit from cheaper shipping rates. Once returned to the destination place this box can be opened on one side to allow passage to the strip to unroll. This packing box can

  moreover, to be open-hatched, ie formed of plan-

  spaced apart from each other which can allow on the one hand the passage of the strip to unroll, on the other hand

  access to the sliding bearings to loosen them to allow

  put the rotation of the roll during unrolling.

  Eventually the crate can be built in a rustic way

  tick, sufficiently resistant for transport (eg

  sawn timber) so as to constitute an inexpensive and destructible packaging at the reception. The easel or the remaining bridge-pallet thus forms a smaller article than the shipping package so that we can often consider the recovery by return

to the shipper or the manufacturer.

  In addition to the setting of the roll obtained by the clamping of the opening of the easel, the packing box can still comprise internally means of wedging, such as crosspieces or longitudinal members, resting on the roller for

  maintain it in the axial direction and / or in the rotary direction.

  An exemplary embodiment of the device according to the invention is now described below with reference to the accompanying drawings in which: FIGS. 1,2 and 3 are views in elevation, side and perspective of the bridge-pallet assembly, - fig. 4 is a perspective view of this loaded set

  of a conveyor belt and packed in a box of

  pedition. - figs. 5 and 6 are sectional views of front and

  profile showing another embodiment.

  As seen more especially in figs. 1 to 3

  positive essentially comprises a bridge 1 mounted on a

horizontal pallet 2.

  The bridge itself includes a horizontal rigid frame 3

- 4 -

  shaped frame made of metal profiles. On the longitudinal members 4 of this frame are fixed two lateral supports 5 each formed of two oblique uprights 6 and a vertical strut 7 fixed to the lower bearing surface 8 of an opening bearing which is completed by a semi-circular stirrup 9

  tightened by means of bolts 10. The assembly, made for example by

  pleated metal profiles and / or welded tubes constitutes a rigid support for the carrier band 11, which is wound on a cylindrical core 12 which has

  end bearing surfaces 13 protruding from each side of the roll.

  These spans 13 are received in the bearings 8 that are re-

  closes by means of the stirrups 9 to immobilize the core 12 in rotation. Preferably bearings 8 of the bearings are supplemented on the outer side by side plates 14 immobilizing the core 12 in the axial direction. These plates are indented to disengage the axial recess 15 of the core 12, for example for the passage of a shaft or lifting sling. The pallet 2 is a classic type pallet, with two longitudinal members 16 and two wooden cross members 17, but it is

  arranged in relation to the bridge 1 so that its lanyards

  16 are located under the longitudinal members 4 of the chassis of this

  last, to which they are attached (ie perpendicular

  vertical stretching of the axis of the roll) while the cross members 17 are located under the side members 16 to raise the latter relative to the ground. In this way the pallet 2 can be taken by the fork of a forklift of conventional type this fork being entangled.

  laterally along the arrow Fl, ie parallel

  at the axis of the roll. This arrangement makes it possible to lift the assembly under better balancing conditions on the carriage. As a variant, it would be possible to provide, beneath the sleepers 17, support pads on the ground parallel to the stays 16 and raising these sleepers in order to allow the pallet to be gripped also in the frontal direction by the

  fork of the truck intriduite according to the F2 fleche.

  We also note that the pallet 2 is arranged to inflate

  Rer or overflow the frame of the bridge 1 so that this pallet can be used conveniently to constitute by itself the bottom of a packing box 18 which encloses the bridge-pallet and roller assembly. The device obtained is illustrated in fig.4 which shows a box of

  slatted type formed of spaced wooden planks.

  This box further comprises at its upper part, under its cover, two crosspieces 19 which are applied against the cylindrical surface of the roller 11 and which form friction pads opposing the rotation of the roller

  during the expedition, completing in this way the immovable

  due to the tightening of the stirrups 9. For a similar purpose

  the body may further comprise two longitudinal members 20 ensuring the lateral setting of the roller and supplementing if necessary its setting in rotation by friction on the circular side faces of the roller. These crosspieces 15 and longitudinal members 20

  are assembled so that they can be easily removed.

  This crate is preferably built in a rustic way

  sawn timber so that it can be easily opened

  te, or even destroyed at the reception to clear the band to unroll. After unwinding the remaining bridge-pallet can be recovered by return to

the sender.

  Naturally, in addition to the possibility of handling by forklift, the entire body can also be lifted by conventional means, for example by

  slings 21, especially for shipments.

  Figs. 5 and 6 show another arrangement applicable when it is desired to use a pallet easel for transporting a strip narrower than the width for which it is normally provided. It has been seen above that the winding core 12 of the strip is itself wedged axially in the bearings 13, but it may be desirable in addition to maintain laterally the wound strip 11 when it is narrower. In this case we plan on

  the core 12 two collars 22 adjustable axially and po-

  be tightened on the core to ensure axial clamping of the band. These collars 22 are preferably in two half-circular opening parts tightened by bolts,

  each having radial arms 23 for lateral retention

  ral of the rolled tape 1i during transport.
