  "Bras perfectionné pour dispositifs de stockage et/ou de reprise à chaînes sans fin articulées et palettes"  <EMI ID=1.1> 

  
dispositifs de stockage et/ou de reprise à chaînes sans fin ticulée et palet tes .

  
Des dispositifs de ce genre, souvent appelés gratteurs,

  
 <EMI ID=2.1> 

  
phates et similaires et/ou pour la reprise des matières ains:
stockées.

  
 <EMI ID=3.1> 

  
tiné à se déplacer, sur rails ou chenilles, le long de l'airE stockage. Ledit équipage est pourvu d'un bras pivotant suppc

  
 <EMI ID=4.1> 

  
duit à stocker ou à reprendre. On trouvera la description d' tel dispositif, mixte en l'occurrence, dans le brevet US

  
n[deg.] 4.018.323.

  
 <EMI ID=5.1> 

  
tanément quatre fonctions, à savoir : transmettre la traction cessaire à mouvoir les palettes dans le sens désiré; supporte et maintenir les palettes normales au bras, malgré la réactio du produit manutentionné; maintenir les palettes centrées par rapport à l'axe du bras; et enfin, supporter leur poids propr ainsi que celui des palettes. Le cumul de ces fonctions entr des contraintes importantes (traction et frottements) sources d'usure rapide et de consommation d'énergie importante.

  
Le but de l'invention est dès lors de fournir un bras pe:
fectionné, dans lequel lesdites chaînes ne remplissent que la seule fonction de traction.

  
A cet effet, un bras selon l'invention se caractérise en

  
 <EMI ID=6.1> 

  
chacun un galet ainsi qu'une attache de palette, ces galets é1 destinés à parcourir des pistes prévues à cet effet sur ledit

  
 <EMI ID=7.1>  

  
moins un galet parallèle à l'axe longitudinal de ladite palett et destiné à s'engager entre deux guides de centrage portés pa ledit bras:

  
Pour plus de clarté, un exemple de réalisation de i'inven est décrit ci-après, avec référence aux dessins schématiques annexés, dans lesquels :
la figure 1 représente un dispositif mixte, c'est-à-dire  stockage et de reprise, équipé d'un bras selon l'invention; la figure 2 est une coupe, à échelle agrandie, selon la trace II-II de la figure 1;

  
 <EMI ID=8.1> 

  
gués respectivement par F3 et F4 à la figure 2; et la figure 5 est une vue agrandie selon la flèche F5 de la gure 2. La figure 1 a pour seul but de montrer un type d'engin auquel s'adresse l'invention. Il est constitué par un équipage mobile 1 monté sur rails disposés le long d'une aire de stockag <EMI ID=9.1> 

  
extrémités sur ledit équipage 1. Un transporteur 4 peut soit amener des produits à stocker au bras 3, soit évacuer les produits repris par celui-ci. Comme dit ci-avant, plus de détails quant à la construction et au fonctionnement de cet engin peuve être trouvés dans le brevet US n[deg.] 4.018.323.

  
Le bras 3 sapporte deux chaînes sans fin 5 portant à leur

  
 <EMI ID=10.1> 

  
plan vertical contenant l'axe géométrique du bras, il suffit de décrire l'une des chaînes et les éléments y associés.

  
Une chaîne 5 est constituée par des maillons 7 mutuellemeni articulés à l'aide d'axes 8. Ces derniers sont ici plus longs que de coutume et leurs extrémités sont filetées. Des attaches

  
 <EMI ID=11.1> 

  
chaîne 5, à raison de deux attaches par axe. 

  
Chacune de ces attaches est constituée par une plaque d'alli

  
 <EMI ID=12.1> 

  
deux axes 8 voisins. L'un des côtés de cette plaque 10 s'étend orthogonalement à la direction de l'axe géométrique du bras et ce côté est pourvu d'une lèvre 11 pour la fixation d'une palette.

  
Un galet 12 à roulement étanche est enfilé sur chaque axe 8 puis des écrous de sécurité 13 viennent fermement bloquer attaches 9 et galets 12 sur leurs axes 8 respectifs.

  
Les palettes 6 sont chacune constituées par une lame d'aciez
14 à section transversale substantiellement en forme de V.

  
Les galets 12 du brin supérieur de la chaîne 5 roulent sur

  
 <EMI ID=13.1> 

  
ceux du brin inférieur roulent dans un profilé en U 16 porté par ledit bras.

  
Chaque palette 6 porte en son centre un galet 17 parallèle

  
 <EMI ID=14.1> 

  
entre deux guides de centrage 18 et 19 prévus sur le bras 3

  
L'ensemble ainsi décrit permet donc d'utiliser la chaîne uniquement comme élément de traction et de lui appliquer une

 <EMI ID=17.1> 

  
tel que décrit et revendiqué.

  
Ainsi, l'usage d'écrous de sécurité peut être remplacé par tout autre système, tel que rivetage etc ...

  
Par ailleurs les attaches de palettes pourraient constituer

  "Improved arm for storage and / or recovery devices with articulated endless chains and pallets" <EMI ID = 1.1>

  
storage and / or take-back devices with endless chains and pallets.

  
Devices of this kind, often called scrapers,

  
 <EMI ID = 2.1>

  
phates and the like and / or for the recovery of raw materials:
stored.

  
 <EMI ID = 3.1>

  
tiné to move, on rails or tracks, along the airE storage. Said crew is provided with a swivel arm suppc

  
 <EMI ID = 4.1>

  
must store or take back. The description of such a device, mixed in this case, can be found in the US patent.

  
n [deg.] 4,018,323.

  
 <EMI ID = 5.1>

  
temporarily four functions, namely: transmitting the secondary traction to move the pallets in the desired direction; support and maintain pallets normal to the arm, despite the reaction of the product handled; keep the pallets centered relative to the axis of the arm; and finally, support their own weight as well as that of the pallets. The combination of these functions between significant constraints (traction and friction) sources of rapid wear and significant energy consumption.

  
The object of the invention is therefore to provide an arm eg:
in which said chains fulfill only the traction function.

  
To this end, an arm according to the invention is characterized by

  
 <EMI ID = 6.1>

  
each a roller as well as a pallet attachment, these é1 rollers intended to traverse tracks provided for this purpose on said

  
 <EMI ID = 7.1>

  
at least one roller parallel to the longitudinal axis of said pallet and intended to engage between two centering guides carried by said arm:

  
For clarity, an exemplary embodiment of the invention is described below, with reference to the appended schematic drawings, in which:
Figure 1 shows a mixed device, that is to say storage and recovery, equipped with an arm according to the invention; Figure 2 is a section, on an enlarged scale, according to trace II-II of Figure 1;

  
 <EMI ID = 8.1>

  
fords respectively by F3 and F4 in Figure 2; and FIG. 5 is an enlarged view along arrow F5 in FIG. 2. The sole aim of FIG. 1 is to show a type of machine to which the invention is addressed. It consists of a mobile equipment 1 mounted on rails arranged along a storage area <EMI ID = 9.1>

  
ends on said equipment 1. A transporter 4 can either bring products to be stored on the arm 3, or evacuate the products taken up by the latter. As said above, more details on the construction and operation of this machine can be found in US Patent No. [deg.] 4,018,323.

  
The arm 3 brings two endless chains 5 bringing to their

  
 <EMI ID = 10.1>

  
vertical plane containing the geometric axis of the arm, it suffices to describe one of the chains and the elements associated with it.

  
A chain 5 is constituted by links 7 mutuellemeni articulated using pins 8. The latter are here longer than usual and their ends are threaded. Ties

  
 <EMI ID = 11.1>

  
chain 5, at the rate of two fasteners per axis.

  
Each of these fasteners is made up of an alloy plate

  
 <EMI ID = 12.1>

  
two neighboring axes 8. One of the sides of this plate 10 extends orthogonally to the direction of the geometric axis of the arm and this side is provided with a lip 11 for fixing a pallet.

  
A roller 12 with sealed bearing is threaded on each axis 8 then safety nuts 13 firmly block fasteners 9 and rollers 12 on their respective axes 8.

  
Pallets 6 each consist of a steel blade
14 with a substantially V-shaped cross section.

  
The rollers 12 of the upper strand of the chain 5 roll on

  
 <EMI ID = 13.1>

  
those of the lower strand roll in a U-shaped section 16 carried by said arm.

  
Each pallet 6 carries in its center a parallel roller 17

  
 <EMI ID = 14.1>

  
between two centering guides 18 and 19 provided on the arm 3

  
The assembly thus described therefore makes it possible to use the chain only as a traction element and to apply a

  
 <EMI ID = 15.1>

  
in the chain by friction are reduced in the ratio of the coefficients of friction steel on steel to that of rolling

  
 <EMI ID = 16.1>

  
10 approx.

  
 <EMI ID = 17.1>

  
as described and claimed.

  
Thus, the use of safety nuts can be replaced by any other system, such as riveting, etc.

  
In addition, the pallet attachments could constitute

  
 <EMI ID = 18.1>

CLAIMS.
