- un organe récepteur recevant chaque train <EMI ID=8.1> 

  
collecteur. Les fascicules de feuilles ainsi constituée sont automatiquement superposés les uns sur les autres avec un petit décalage systématiquement et alternativement provoqué dans un sens puis dans l'autre, à l'arrivée de chaque nouveau train.

  
Une machine de oe type a été mise au point

  
par la même demanderesse et décrite notamment dans le brevet

  
 <EMI ID=9.1> 

  
De semblables machines remplissent leur fonction de façon satisfaisante pour des fascicules comportant un nombre de feuilles relativement important. 

  
Une des condition* auxquelles ce* machines

  
 <EMI ID=10.1> 

  
Le contrôle de la première de ces conditions est, de façon connue en soit notamment obtenu au moyen d'un sabot articulé, disposé à l'extrémité antérieure dos organes entraîneurs. Untel sabot présente deux positions caracté-

  
 <EMI ID=11.1>

 <EMI ID=12.1> 

  
le très crand nombre do fois qu'il est appelé à fonctionner, soit présenter une certaine usure mécanique, soit présenter une certaine défectuosité de nature électrique, contacta perlés, déformés, etc. Dans ces éventualités, la machine assembleuse n'est plus prémunie contre tout risque de fouille manquante.

  
Le fonctionnement d'un tel dispositif peut

  
 <EMI ID=13.1> 

  
papier ou par le dépôt d'encre qui peuvent omp8chor un contact franc entre les parties métalliques assurant l'ou-

  
 <EMI ID=14.1> 

  
pour cette détection. 

  
Le contrôle de la seconde de ces conditions est généralement obtenu au moyen d'un mécanisme à jauge d'épaisseur, qui actionne également un contact électrique

  
 <EMI ID=15.1> 

  
doublée , 9 mécanisme qui présente les mimes inconvénients

  
que ceux citée plus haut.

  
Afin de remédier à ces inconvénients, la demanderesse a imaginé de perfectionner ces dispositifs connus de telle façon qu'il ne soit plus possible d'envisager un défaut quelconque dans leur fonctionnement*

  
Le dispositif, objet de la présente invention, est constitué par un type particulier d'organe entraîneur

  
de la feuille supérieure de chacun des paquets de fouilles disposés dans les casiers faisant partie d'une machine assembleuse, du genre de celle décrite ci-dessus.

  
Ce dispositif sera défini plus loin de façon plus précise après la description d'un exemple de réalisation repria aux figures ci-jointes.

  
La figure 1 représente de façon schématique et non à l'échelle une machine assembleuse munie du dispositif de l'invention, les figures 2 et 3 représentent un croquis agrandi de l'extrémité antérieure des organes entraîneurs,

  
en position d'entraînement (fig. 2) et de retour (fig. 3).

  
La figure 4 représente une vue en plan schématique de l'étrier d'extrémité de la hampe, la figure 3 représente une vue en élévation de ce même étrier, vue suivant la floche 15. 

  
Sur la figure 1, on peut voir en 1 la châssis de la machine, en 2 la batterie des casiers incliné* con-

  
 <EMI ID=16.1> 

  
mouvement de va-et-vient dans le sens de la flèche 5 Par tout moyen connu en soi. La tringle 4 sort de support aux

  
 <EMI ID=17.1> 

  
collectrice 9 (par son brin inférieur 10) et une série de rouleaux 11. L<1> entraînement des feuilles est réalisé dans le sens de la flèche 12, l'ensemble des feuilles constituant

  
 <EMI ID=18.1> 

  
mité de la machine, dans un organe récepteur approprié.

  
Sur les figures 2 et 3, on peut observer en coupe longitudinale en 3 le paquet de feuilles disposé

  
dans un des casiers dont le fond est on 14. La figure 2 montre la tête 8 en position ascendante (flèche 15), la figure 3 montra la tête 8 en position descendante (flèche 16).

  
La tête 8, fixée à l'extrémité de la hampe métallique 17, est en un matériau non conducteur 18, terminé en 19 par une portée cylindrique d'axe 20 parallèle à celui de la hampe 17 et servant de pivot de rotation à un patin d'entraînement. Celui-ci est constitué d'un étrier 21 pivotant sur les pivota 22 d'un balancier 23, pouvant lui-

  
 <EMI ID=19.1> 

  
permettant le passage d'un tambour cylindrique 26 en un matériau rugueux, en une ou plusieurs sections, et muni à sa périphérie d'une denture axiale 27* Ce tambour est

  
 <EMI ID=20.1> 

  
La partie arrière de l'étrier est munie d'un bras 28 supportant, fixée à son extrémité, une pastille aimantée 29.

  
L'arrière de la tête 8 présente un évidement

  
 <EMI ID=21.1> 

  
aux deux extrémités duquol sont soudés deux raccords électriques en 32 et 33. Ces deux raccords sont reliés au reste du dispositif électrique de la machine, à l'intervention de la hampe, . l'intérieur du profil de laquelle ils sont fixés. Ces raccords servent à la signalisation des feuilles manquantes.

  
Ainsi constitué, le dispositif fonctionne comme suit : lors de la phase ascendante (fige 2) la tête 8 repose sur la première feuille du paquet par le tambour

  
rugueux 26. Sous ce mouvement, l'étrier complet tourne au-

  
 <EMI ID=22.1> 

  
jusqu'à ce que l'aimant 29 vienne au contact de la face

  
 <EMI ID=23.1> 

  
repousse la lamelle 35 contre l'extrémité de la lamelle 36 établissant ainsi un contact électrique. Ces deux extrémités de lamelles 35 et 36 se trouvent à l'intérieur d'une ampoule étanche 38, soit sous vide, soit sous atmosphère

  
à faible pression, d'un gaz inerte ou sans action sur les

  
 <EMI ID=24.1> 

  
arrêtée, le tambour 26 a'arrête aussi et, suivant en cela le mouvement ascendant de la tête 8, entraîne vers le haut la première feuille 37 du paquet* Cet entraînement dure jusqu'à l'instant où la partie antérieure de la feuille 37 est happée par les courroies collectrices 10. A ce moment, chaque feuille 37 provoque la rotation du tambour 26 en

  
 <EMI ID=25.1> 

  
suffisamment loin de l'ampoule 38 pour que les deux lamelles
35 et 36 s'écartent l'une de l'autre, reprenant ainsi leur position naturelle en l'absence de toute sollicitation.

  
Si dans l'un quelconque des casiers, une feuille vient à ne pas être entraînée, en fin de course il ne se produira pas de rotation de l'étrier correspondant et le circuit électrique de la hampe restera fermé, ce qui

  
 <EMI ID=26.1> 

  
tuosité du fonctionnement de la machine et du casier défectueux ou vide. 

  
 <EMI ID=27.1> 

  
que la fouille supérieure présente au cours de son déplacement une certaine avance sur la feuille sous-jacente, Il N'ensuit

  
 <EMI ID=28.1> 

  
fouille supérieure, laquelle continue son trajet ascendante puisqu'elle est happée par les courroies collectrices. Le

  
bras 28 vient ensuite au contact de l'arrière de la feuille 'loue-jacente qu'il coince entre lui -mené et le paquet de feuilles. Si à ce moment, la feuille supérieure est encore

  
au contact du tambour 26, le frottement qu'elle exercera

  
sur celui-ci, solidaire de l'étrier 21, le forcera à tourner autour de l'axe des tourillon* 22, ce qui d'une part tend

  
à dégager le tambour 26 de aon contact avec la fouille supérieure ainsi libérée et, d'autre part, accentue la pression du

  
bras 28 sur l'arriére de la feuille sous-jacente. Cette

  
feuille, non seulement ne pourra ainsi plus suivre la feuille supérieure, mais sera contrainte de redescendre Jusqu'au

  
fond du casier sous la force d'entraînement du bras 28

  
au cours de son mouvement de descente. 

  
 <EMI ID=29.1> 

  
Ayant ainsi décrit une modalité de réalisation

  
 <EMI ID=30.1> 

  
les caractéristiques essentielles*

  
Le dispositif, objet de la présente invention, lequel est destiné à être utilisé plus spécialement comme

  
 <EMI ID=31.1> 

  
d'une machine assembleuse de fouillée, dispositif constitué d'une tige dont l'extrémité postérieur* est munie d'un organe de liaison,( par exemple un articulation) avec la partie de la machine qui lui transmet son mouvement de va-et-vient,

  
et dont l'extrémité antérieure est munie d'un patin de frottement articulé sur la dite extrémité de façon à pouvoir tourner autour d'un axe parallèle à celui de la tige, ou sensiblement parallèle à oelui-di, et de préférence peu distant de cet axe et d'autre part également autour d'un axe sensiblement perpendiculaire au premier, est essentiellement caractérisé en ce que lo dit patin comporte d'une part un organe de frottement en matériau rugueux, solidaire du dit

  
 <EMI ID=32.1> 

  
hampe sur les fouilles, le contact soit établi par l'intermédiaire du dit organe de frottement, en ce que le dit patin  <EMI ID=33.1> 

  
non mines en contact l'un. avec l'autre suivant la position de l'aimant solidaire du patin et tournant avec lui.

  
 <EMI ID=34.1> 

  
 <EMI ID=35.1> 

  
variante permet d'assurer un nombre exceptionnellement élevé de fonctionnement sans crainte quelconque d'un fonctionnement défectueux et sans crainte d'usure des contacts pour quelque motif que ce soit, usure, poussière de papier, encre, etc ...

  
Suivant une autre variante avantageuse de ce dispositif, l'organe de frottement, solidaire du patin est

  
) constitué d'un cylindre en caoutchouc ou matière analogue, cylindre dont l'axe est sensiblement perpendiculaire à celui

  
de la hampe et dont la périphérie est munie de rainures disposées suivant l'axe du cylindre ou de toute autre manière ayant pour effet d'assurer un entraînement des feuilles rigoureusement dans le sens de l'axe longitudinal des casiers. 

  
 <EMI ID=36.1> 

  
du patin, ainsi que l'organe de frottement sont située

  
de part et d'autre du plan qui, passant par l'nxe de rotation du patin perpendiculairement à la hampe, est perpendiculaire au plan des fouille* du paquet, au moins pendant la phase descendante de la hampe. De cette façon, pendant cette phase,

   <EMI ID = 1.1>

  
such as paper searches "

  
 <EMI ID = 2.1>

  
Such machines have been known for a long time; they usually have more than one frame

  
 <EMI ID = 3.1>
- a number of lockers, the most <EMI ID = 4.1> <EMI ID = 5.1>
- a certain number of components intended to drive the upper spinner of each package do not find <EMI ID = 6.1> of one or more belts @ parallel to each other and continuously entraining the @ leaves coming out of the bins,

  
 <EMI ID = 7.1>

- a receiving unit receiving each train <EMI ID = 8.1>

  
collector. The bundles of sheets thus formed are automatically superimposed on each other with a small shift systematically and alternately caused in one direction then in the other, at the arrival of each new train.

  
A typical machine has been developed

  
by the same applicant and described in particular in the patent

  
 <EMI ID = 9.1>

  
Similar machines perform their function satisfactorily for booklets comprising a relatively large number of sheets.

  
One of the conditions * under which this * machines

  
 <EMI ID = 10.1>

  
The control of the first of these conditions is, in a manner known per se, in particular obtained by means of an articulated shoe, arranged at the anterior end of the driving members. Such a shoe has two characteristic positions

  
 <EMI ID = 11.1>

  
upper part of one of the packages and the so-called tilted one

  
 <EMI ID = 12.1>

  
the very large number of times that it is called upon to operate, either present a certain mechanical wear, or present a certain defect of an electrical nature, contact with beaded, deformed, etc. In these eventualities, the assembling machine is no longer protected against any risk of missing excavation.

  
The operation of such a device may

  
 <EMI ID = 13.1>

  
paper or by the deposition of ink which can omp8chor a clear contact between the metal parts ensuring the ou-

  
 <EMI ID = 14.1>

  
for this detection.

  
Control of the second of these conditions is usually achieved by means of a feeler gauge mechanism, which also actuates an electrical contact.

  
 <EMI ID = 15.1>

  
doubled, 9 mechanism which presents the same drawbacks

  
than those cited above.

  
In order to remedy these drawbacks, the applicant has imagined improving these known devices in such a way that it is no longer possible to envisage any defect in their operation *

  
The device, object of the present invention, is constituted by a particular type of drive member

  
of the top sheet of each of the excavation packages arranged in the racks forming part of a collating machine, of the type described above.

  
This device will be defined more precisely below after the description of an exemplary embodiment given in the accompanying figures.

  
Figure 1 shows schematically and not to scale an assembling machine provided with the device of the invention, Figures 2 and 3 show an enlarged sketch of the front end of the driving members,

  
in the drive position (fig. 2) and return (fig. 3).

  
Figure 4 shows a schematic plan view of the end bracket of the shaft, Figure 3 shows an elevational view of the same bracket, seen along the arrow 15.

  
In figure 1, we can see in 1 the frame of the machine, in 2 the battery of inclined lockers * con-

  
 <EMI ID = 16.1>

  
back and forth movement in the direction of arrow 5 By any means known per se. Rod 4 comes out of the support

  
 <EMI ID = 17.1>

  
collector 9 (by its lower strand 10) and a series of rollers 11. L <1> drive of the sheets is carried out in the direction of arrow 12, the set of sheets constituting

  
 <EMI ID = 18.1>

  
mity of the machine, in an appropriate receiving member.

  
In Figures 2 and 3, one can observe in longitudinal section 3 the packet of sheets arranged

  
in one of the racks whose bottom is on 14. Figure 2 shows the head 8 in the upward position (arrow 15), Figure 3 shows the head 8 in the downward position (arrow 16).

  
The head 8, fixed to the end of the metal shaft 17, is made of a non-conductive material 18, terminated in 19 by a cylindrical bearing with an axis 20 parallel to that of the shaft 17 and serving as a pivot of rotation for a pad training. This consists of a caliper 21 pivoting on the pivots 22 of a balance 23, which can itself be

  
 <EMI ID = 19.1>

  
allowing the passage of a cylindrical drum 26 made of a rough material, in one or more sections, and provided at its periphery with axial teeth 27 * This drum is

  
 <EMI ID = 20.1>

  
The rear part of the caliper is provided with an arm 28 supporting, fixed at its end, a magnetic pad 29.

  
The back of the head 8 has a recess

  
 <EMI ID = 21.1>

  
at both ends duquol are welded two electrical connectors 32 and 33. These two connectors are connected to the rest of the electrical device of the machine, to the intervention of the shaft,. inside the profile of which they are attached. These connectors are used to signal missing sheets.

  
Thus constituted, the device operates as follows: during the ascending phase (freeze 2) the head 8 rests on the first sheet of the pack by the drum

  
rough 26. Under this movement, the entire caliper rotates

  
 <EMI ID = 22.1>

  
until the magnet 29 comes into contact with the face

  
 <EMI ID = 23.1>

  
pushes the sipe 35 against the end of the sipe 36 thus establishing an electrical contact. These two ends of strips 35 and 36 are located inside a sealed ampoule 38, either under vacuum or under atmosphere.

  
at low pressure, with an inert gas or without action on the

  
 <EMI ID = 24.1>

  
stopped, the drum 26 also stops and, following in this the upward movement of the head 8, drives upwards the first sheet 37 of the pack * This drive lasts until the moment when the front part of the sheet 37 is caught by the collector belts 10. At this moment, each sheet 37 causes the rotation of the drum 26 in

  
 <EMI ID = 25.1>

  
far enough from the bulb 38 so that the two blades
35 and 36 move away from each other, thus resuming their natural position in the absence of any stress.

  
If in any of the compartments, a sheet does not come in, at the end of the stroke there will be no rotation of the corresponding stirrup and the electrical circuit of the pole will remain closed, which

upper trench, which continues its upward path since it is caught by the collector belts. The

  
arm 28 then comes into contact with the rear of the sheet 'rent-underlying which it wedges between itself and the packet of sheets. If at this time the top sheet is still

  
in contact with the drum 26, the friction it will exert

  
on this, integral with the caliper 21, will force it to turn around the axis of the trunnions * 22, which on the one hand tends

  
to release the drum 26 from contact with the upper excavation thus released and, on the other hand, increases the pressure of the

  
arm 28 on the back of the underlying sheet. This

  
sheet, not only will thus no longer be able to follow the upper sheet, but will be forced to descend

  
bottom of the locker under the driving force of the arm 28

  
during its descent movement.

the essential characteristics *

  
The device, object of the present invention, which is intended to be used more especially as

  
 <EMI ID = 31.1>

  
of a digging assembly machine, device consisting of a rod whose rear end * is provided with a connecting member (for example an articulation) with the part of the machine which transmits its back-and-forth movement to it - comes,

  
and the front end of which is provided with a friction pad articulated on said end so as to be able to rotate about an axis parallel to that of the rod, or substantially parallel to oelui-di, and preferably not far from this axis and on the other hand also around an axis substantially perpendicular to the first, is essentially characterized in that said shoe comprises on the one hand a friction member made of rough material, integral with said

  
 <EMI ID = 32.1>

  
shaft on the excavations, contact is established through said friction member, in that said pad <EMI ID = 33.1>

  
no mines in contact one. with the other depending on the position of the magnet integral with the pad and rotating with it.

  
 <EMI ID = 34.1>

  
 <EMI ID = 35.1>

  
This variant ensures an exceptionally high number of operations without any fear of faulty operation and without fear of contact wear for any reason whatsoever, wear, paper dust, ink, etc.

  
According to another advantageous variant of this device, the friction member, integral with the pad is

  
) consisting of a cylinder of rubber or similar material, the axis of which is substantially perpendicular to that

  
of the shaft and the periphery of which is provided with grooves arranged along the axis of the cylinder or in any other manner having the effect of ensuring a drive of the sheets strictly in the direction of the longitudinal axis of the boxes.

  
 <EMI ID = 36.1>

  
of the pad, as well as the friction member are located

  
on either side of the plane which, passing through the axis of rotation of the pad perpendicular to the shaft, is perpendicular to the plane of the searches * of the package, at least during the downward phase of the shaft. In this way, during this phase,
