Definitions
- the present invention relates to a machine for selecting bottles of different heights brought by a conveyor and evacuated by at least two conveyors, the selection being effected by a wheel with a vertical axis comprising cells corresponding to the vertical bottles, each of the cells comprising a means intermittent retention of its bottle actuated by a height detector of said bottle.
- Bottlers from returnable bottles, or at least to reuse, have to face difficulties caused by the different heights of bottles. Indeed, in addition to the difficulties encountered during the bottling of the corking and the capping, the bottles are grouped in packages or cardboard boxes which must contain bottles of the same heights under penalty of encountering difficulties in stacking loads.
- the bottles are brought, on a conveyor, to scroll one by one in front of an apparatus which grabs it and directs it on at least two different conveyors according to its height detected by light rays at appropriate height which come to activate photosensitive cells which emit a signal likely to place the bottle on the conveyor which corresponds to its height.
- a first system consists of a mechanical ejection pusher.
- the disadvantages of these pushers are numerous, they require a relatively large lateral clearance so that the pushbutton arrives with a certain speed on the side of the bottle. This causes bottles to fall or even breakage; in any case, the selection speed is relatively low.
- a second system provides for the referral of the bottles by jets of compressed air; this has the disadvantage of unbalancing the bottles which fall sometimes this system is suitable for bottles of low height, like cans, but is not suitable for normal bottles.
- a third system uses a wheel with a vertical axis comprising cells with, at the bottom of each cell, a suction cup connected, by pipes and valves, to a vacuum pump.
- the wheel therefore has mechanical systems which weigh it down and which are fragile.
- the wheel is therefore positively driven by its axis and it is this which determines the flow rate of the machine to be selected.
- This system allows a large flow but the mechanics placed inside the cell wheel is fragile and bulky, which requires the use of a large diameter cell wheel. In any case, this mechanism is expensive and is not suitable for medium-sized bottling plants.
- the present invention is intended to remedy the drawbacks of the devices briefly described above by improving the wheel system with vertical axis with the cells.
- Another characteristic of the invention resides in the fact that the selection of vacuum suction cups is done by shutters integral with the stationary part of the bearing and which come to plug, respectively open holes relating to each of the suction cups opening onto the upper flank of the cell wheel to establish respectively breaking, the vacuum in the corresponding suction cup.
- each suction cup can be achieved from a vacuum pump and it is broken by shutters which open openings relating to each suction cup at the desired time.
- it is caused by a venturi where we admit compressed air normally escaping through holes which can be closed by shutters in which case the corresponding suction cup blows air at instead of sucking it up.
- the height detector of the invention lies in the fact that it is of the type with a pair of optical fibers, one of the groups of fibers emitting a radiation which, after possible reflection on the top of the bottle, returns partially to the second group of fibers which directs it towards a photosensitive element which determines a current which is amplified appropriately and controls or not the suction of the suction cup.
- the machine of the invention obviously avoids the disadvantages of all devices with mechanical pushers and pushing by air jets. It also avoids the drawbacks of the cell wheel (sometimes called "star") since here said wheel can be made very slightly since it contains no mobile mechanics. Therefore, it does not include any mechanical drive means. It is driven by the bottles themselves which are pushed by the transporter of a Congresso
- the machine of the invention selects bottles brought by the conveyor (1) according to the arrows (2, 3), and evacuated by the conveyors (4) and (5) according to the arrows (6, 7).
- the selection is made by a wheel (8) with a vertical axis (9) rotating in a bearing (10) comprising bearings (11, 12).
- the wheel (8) has cells such as (13) corresponding to the vertical bottles.
- a suction cup such as (14) made of elastic material.
- Each suction cup (14) is screwed by a nozzle ( 1 5) into the wheel hub (8) and has a hole coaxial with the suction cup (14) which opens into a vertical hole ( 1 6) corresponding to the bottom of each cell (13).
- each suction cup (14) is connected to the part of small section of a venturi (17) placed in the hole (16).
- the hole (16) receives, at its lower part, compressed air from radial holes such as (18), (181) which radiate from an axial hole (19) leading to a rotary joint (20 ) whose the fixed part is connected to a compressed air pipe (21).
- the top of the vertical holes (16) opens onto the upper flank of the wheel hub (8) and, when it is not closed, the compressed air passing through each venturi (17) causes vacuum in the suction cup ( 14).
- This vacuum can be broken by a movable (22) or fixed (23) shutter.
- the fixed shutter (23) automatically closes the top of the holes (16) when they slide against its lower part.
- the shutter (22) does the same when the lower portion (2 4) is at the top of the hole (16). However, the plate (24) can be lifted in the direction of the arrow (25) from a jack (not shown) which lifts the shutter (22) by sliding it in appropriate vertical slides. At this time, the shutter has no effect and the vacuum is "broken" in the corresponding suction cup (14).
- the shutters (22) and (23) are screwed onto the bearing housing (10) at angular locations determined by the place where one wishes to make the selection and at a height which is adjustable to ensure correct operation.
- the action of the double-acting cylinder controlling the movement of the shutters (22) is done automatically using a solenoid valve which is controlled, from strong currents emitted in a control box which receives light signals coming from a detector which is shown schematically in Figure 4.
- a solenoid valve which is controlled, from strong currents emitted in a control box which receives light signals coming from a detector which is shown schematically in Figure 4.
- detectors which are shown schematically in Figure 4.
- detectors one upper (26) and the other lower (27)
- each comprising two groups of optical fibers one bringing in light radiation (28) the other bringing back any reflected radiation ( 2 9) .
- These two optical fiber pairs are indicated by (281) and (291) in the sensor (2 7). If the light emanating from the fiber (28) dissipates in a vacuum along the ray (30), there is no ray brought back by the fiber (29).
- a photosensitive cell located in the at the other end of the fiber junction box, determines a current that is supplied to a f icateur amplified to produce a strong current that will be used in the control solenoid of the movable shutter (22).
- the bearing housing ( 1 0) has facets (34, 35, 36) intended to fix there either the shutters (22) or (23), or a support (37) or (38) having an axis such as (39 ) that can be blocked in a yoke (40) fixed to the end of a movable arm (41) that can also be blocked in a yoke (42) secured to the frame of the machine.
- the conveyors (4) and (5) are of the chain type with flat shoes and are obviously bordered by lateral guides shown diagrammatically by the lines (43).
- the conveyor (1) brings the bottles along the arrows (2) and (3) which are thus pushed into each of the cells (13), helped in this by the elastic blade (44) which pushes although thoroughly the bottle against the sucker (14) corresponding to ante.
- This suction cup, in each of the cells turned on the side of the conveyor (1), is still in the suction stage since there is no shutter in this sector.
- the machine of the invention can also operate with a vacuum pump, in which case a fixed shutter would be placed on the entire underside of the bearing housing (10) except in the places where there are the two shutters ( 22) and (23). In place of the shutter (23) there would be nothing. In place of the shutter (22) there would be a movable shutter which would act opposite the shutter (22) which has been described, that is to say which would rise to let the bottles leave in the transporter (4) and which would lower to drive them to the transporter (7), which is the reverse of what has been described above. The advantages would be the same Since there is no movable selection member on or in the wheel (8).
Abstract
Description
La présente invention concerne une machine à sélectionner les bouteilles de hauteurs différentes amenées par un transporteur et évacuées par au moins deux transporteurs, la sélection d'effectuant par une roue à axe vertical comportant des alvéoles correspondants aux bouteilles verticales, chacun des alvéoles comprenant un moyen de rétention intermittent de sa bouteille actionné par un détecteur de hauteur de ladite bouteille.The present invention relates to a machine for selecting bottles of different heights brought by a conveyor and evacuated by at least two conveyors, the selection being effected by a wheel with a vertical axis comprising cells corresponding to the vertical bottles, each of the cells comprising a means intermittent retention of its bottle actuated by a height detector of said bottle.
Les embouteilleurs, à partir de bouteilles consignées, ou tout au moins à réemployer, ont à faire face à des difficultés provoquées par les hauteurs différentes de bouteilles. En effet, en plus des difficultés rencontrées lors de l'embouteillage du bouchage et du capsulage, les bouteilles sont groupées dans des paquets ou cartonnages qui doivent contenir des bouteilles de mêmes hauteurs sous peine de rencontrer des difficultés d'empila.ge de fardeaux.Bottlers, from returnable bottles, or at least to reuse, have to face difficulties caused by the different heights of bottles. Indeed, in addition to the difficulties encountered during the bottling of the corking and the capping, the bottles are grouped in packages or cardboard boxes which must contain bottles of the same heights under penalty of encountering difficulties in stacking loads.
On est donc amené à devoir trier des bouteilles suivant leur hauteur.We therefore have to sort bottles according to their height.
Les bouteilles sont amenées, sur un transporteur, à défiler une à une devant un appareillage qui la saisit et l'oriente sur au moins deux transporteurs différents suivant sa hauteur détectée par des rayons lumineux à hauteur appropriée qui viennent exciter des cellules photosensibles qui émettent un signal susceptible de placer la bouteille sur le transporteur qui correspond à sa hauteur.The bottles are brought, on a conveyor, to scroll one by one in front of an apparatus which grabs it and directs it on at least two different conveyors according to its height detected by light rays at appropriate height which come to activate photosensitive cells which emit a signal likely to place the bottle on the conveyor which corresponds to its height.
Il existe différents sytèmes permettant d'aiguiller la bouteille dans la bonne direction.There are different systems to point the bottle in the right direction.
Un premier système consiste en un poussoir d'éjection mécanique. Les inconvénients de ces poussoirs sont nombreux ils exigent un jeu latéra.l relativement important si bien que le poussoir arrive avec une certaine vitesse sur la flanc de la bouteille. Cela provoque des chutes de bouteilles ou même des casses ; de toute façon la vitesse de sélection est relativement faible.A first system consists of a mechanical ejection pusher. The disadvantages of these pushers are numerous, they require a relatively large lateral clearance so that the pushbutton arrives with a certain speed on the side of the bottle. This causes bottles to fall or even breakage; in any case, the selection speed is relatively low.
Un deuxième système prévoit l'aiguillage des bouteilles par des jets d'air comprimé ; ceci a l'inconvénient de déséquilibrer les bouteilles qui tombent parfois ce système est appproprié pour des bouteilles de faible hauteur, comme des cannettes, mais ne convient pas pour les bouteilles normales.A second system provides for the referral of the bottles by jets of compressed air; this has the disadvantage of unbalancing the bottles which fall sometimes this system is suitable for bottles of low height, like cans, but is not suitable for normal bottles.
Un troisième système utilise une roue à axe Vertical comportant des alvéoles avec, au fond de chaque alvéole, une ventouse reliée, par des conduites et des clapets, à une pompe à vide. La roue comporte donc des systèmes mécaniques qui l'alourdissent et qui sont fragiles. La roue e.st donc entrainée positivement par son axe et c'est elle qui détermine le débit de la machine à sélectioner. Ce système permet un grand débit mais la mécanique disposée à l'intérieur de la roue à alvéoles est fragile et encombrante, ce qui oblige à utiliser une roue à alvéoles de grand diamètre. De toute façon ce mécanisme est onéreux et ne convient Pas aux usines d'embouteillage moyennes.A third system uses a wheel with a vertical axis comprising cells with, at the bottom of each cell, a suction cup connected, by pipes and valves, to a vacuum pump. The wheel therefore has mechanical systems which weigh it down and which are fragile. The wheel is therefore positively driven by its axis and it is this which determines the flow rate of the machine to be selected. This system allows a large flow but the mechanics placed inside the cell wheel is fragile and bulky, which requires the use of a large diameter cell wheel. In any case, this mechanism is expensive and is not suitable for medium-sized bottling plants.
Dans tous les cas exposés ci-dessus, on peut très bien utiliser une machine à sélectionner deux tailles de bouteilles ou, plus précisément, des bouteilles au dessus d'une certaine taille et celles en dessous de ladite taille suivant le réglage du détecteur de hauteur. En effet, il suffit d'ajouter d'autres dispositifs de sélection de hauteur au dessus et en dessous d'une certaine taille pour obtenir la sélection de toutes les tailles de bouteilles voulues. Les transporteurs après sélection peuvent se déplacer dans le même sens que les transporteurs avant sélection ou dans des sens obliques ou même perpendiculaires.In all the cases described above, we can very well use a machine to select two sizes bottles or, more precisely, bottles above a certain size and those below said size depending on the setting of the height detector. Indeed, it suffices to add other height selection devices above and below a certain size to obtain the selection of all the desired sizes of bottles. The carriers after selection can move in the same direction as the carriers before selection or in oblique or even perpendicular directions.
La présente invention est destinée à remédier aux inconvénients des dispositifs brièvement décrits ci-dessus en perfectionnant le système à roues à axe vertical avec les alvéoles.The present invention is intended to remedy the drawbacks of the devices briefly described above by improving the wheel system with vertical axis with the cells.
La machine de l'invention est caractérisée principalement par le fait
- que la roue à alvéoles tourne librement sur son axe qui comporte un joint pneumatique tournant destiné à provoquer un vide intermittent amené à des ventouses au fond de chaque alvéole, la sélection des ventouses sous vide se faisant sans organe mobile sur la roue depuis le saisie de la bouteille Jusqu'à son lacher sur le transporteur correspondant à sa hauteur,
- - que le palier de l'axe de la roue est supporté de manière à pouvoir se caler sur un axe excentré supporté lui même Par un bras oscillant immobilisable,
- et que les bouteilles en mouvement sous l'effet du transporteur d'amenée sont poussées au fond de l'alvéole qui leur correspond sous l'effet d'une lame élastique et qu'elles entrainent de ce fait, la roue à alvéoles à axe vertical.
- that the cell wheel turns freely on its axis which has a rotating pneumatic seal intended to cause an intermittent vacuum brought to suction cups at the bottom of each cell, the selection of vacuum cups being made without movable member on the wheel since entering the bottle Until it is dropped on the conveyor corresponding to its height,
- - that the bearing of the wheel axle is supported so as to be able to wedge on an eccentric axle supported itself By an immobilizing swing arm,
- and that the bottles in motion under the effect of the supply conveyor are pushed to the bottom of the cell which corresponds to them under the effect of an elastic blade and they entrain therefore, the cell wheel with a vertical axis.
Un autre caractéristique de l'invention réside dans le fait que la sélection des ventouses sous vide se fait par des obturateurs solidaires de la partie immobile du palier et qui viennent boucher, respectivement ouvrir des trous relatifs à chacune des ventouses débouchant sur le flanc supérieur de la roue à alvéoles pour établir respectivement casser, le vide dans la ventouse correspondante.Another characteristic of the invention resides in the fact that the selection of vacuum suction cups is done by shutters integral with the stationary part of the bearing and which come to plug, respectively open holes relating to each of the suction cups opening onto the upper flank of the cell wheel to establish respectively breaking, the vacuum in the corresponding suction cup.
Comme certaines éjections de bouteilles, en particulier celles qui sont restées dans leur alvéole, sont obligatoires à un certain moment, certains obturateurs sont immobiles, réglés sur le boitier de palier, tandis que d'autres sont mobiles suivant un mouvement alternatif axial verticalement, guidés par des glissières fixées sur ledit boitier, ledit mouvement alternatif étant déterminé Par un vérin à double effet commandé par le détecteur de hauteurs de bouteillesoAs certain bottle ejections, in particular those which have remained in their cell, are compulsory at a certain time, some shutters are stationary, adjusted on the bearing housing, while others are movable in an alternating axial vertical movement, guided by slides fixed to said housing, said reciprocating movement being determined by a double-acting cylinder controlled by the bottle height detector o
Le vide dans chaque ventouse peut être réalisé à partir d'une pompe à vide et il est cassé par des obturateurs qui ouvrent des orifices relatifs à chaque ventouse au moment voulu. Cependant, suivant une forme préférée de réalisation, il est provoqué par un venturi où l'on admet de l'air comprimé s'échappant normalement par des trous qui peuvent être obturés par des obturateurs auxquels cas la ventouse correspondante souffle de l'air au lieu d'en aspirer.The vacuum in each suction cup can be achieved from a vacuum pump and it is broken by shutters which open openings relating to each suction cup at the desired time. However, according to a preferred embodiment, it is caused by a venturi where we admit compressed air normally escaping through holes which can be closed by shutters in which case the corresponding suction cup blows air at instead of sucking it up.
Une caractéristique importante du détecteur de hauteur de l'invention réside dans le fait qu'il est du type à couple de fibres optiques, l'un des groupes de fibres émettant un rayonnement qui, après réflexion éventuelle sur le haut de la bouteille, revient partiellement sur le deuxième groupe de fibres qui le dirige vers un élément photosensible qui détermine un courant qui est amplifié convenablement et commande ou non l'aspiration de la ventouse.An important characteristic of the height detector of the invention lies in the fact that it is of the type with a pair of optical fibers, one of the groups of fibers emitting a radiation which, after possible reflection on the top of the bottle, returns partially to the second group of fibers which directs it towards a photosensitive element which determines a current which is amplified appropriately and controls or not the suction of the suction cup.
La machinede l'invention évite, évidemment, des inconvénients de tous les dispositifs à poussoirs mécaniques et à poussée par jets d'air. Il évite aussi les inconvénients de la roue à alvéoles (appelée parfois "étoile") puisqu'ici ladite roue peut être réalisée très légèrement puisqu'elle ne contient aucune mécanique mobile. De ce fait, elle ne comprend aucun moyen d'entrainement mécanique. Elle est entrainée par les bouteilles elles-même qui sont poussées par le transporteur d'amenéeoThe machine of the invention obviously avoids the disadvantages of all devices with mechanical pushers and pushing by air jets. It also avoids the drawbacks of the cell wheel (sometimes called "star") since here said wheel can be made very slightly since it contains no mobile mechanics. Therefore, it does not include any mechanical drive means. It is driven by the bottles themselves which are pushed by the transporter of amenéeo
Il en résulte un dispositif simple, de petite taille, facile à entretenir puisque les pièces mobiles sont accesibles sans démontage, peu onéreux à fabriquer. On peut donc en multiplier l'usage et obtenir une sélection de hauteurs ou tailles de bouteilles beaucoup plus détaillée.The result is a simple device, small in size, easy to maintain since the moving parts are accessible without disassembly, inexpensive to manufacture. We can therefore multiply the use and obtain a much more detailed selection of heights or sizes of bottles.
Dans la pratique, on est arrivé à trier environ 20 000 bouteilles à l'heure, ce qui satisfait la plupart des installations d'embouteillage.In practice, we have managed to sort about 20,000 bottles an hour, which satisfies most bottling plants.
L'invention sera mieux comprise à l'aide de la description suivante qui en donne un exemple non limitatif de réalisation pratique et qui est illustré par les dessins Joints.The invention will be better understood with the aid of the following description which gives a nonlimiting example of practical embodiment thereof and which is illustrated by the attached drawings.

La machine de l'invention sélectionne des bouteilles amenées par le transporteur (1) suivant les flèches (2, 3), et évacuées par les transporteurs (4) et (5) suivant les flèches (6, 7). La sélection s'effectue par une roue (8) à axe vertical (9) toumant dans un palier (10) comportant des roulements (11, 12). La roue (8) comporte des alvéoles tels que (13) correspondant aux bouteilles verticales. Au fond de chaque alvéole tel que (13), est disposée une ventouse telle que (14) en matière élastique. Chaque ventouse (14) est vissée par un embout (15) dans le moyeu de la roue (8) et comporte un trou coaxial à la ventouse (14) qui débouche dans un trou vertical (16) correspondant au fond de chaque alvéole (13). En fait chaque ventouse (14) est reliée à la partie de faible section d'un venturi (17) placé dans le trou (16). Le trou (16) reçoit, à sa Partie inférieure, de l'air comprimé à partir de trous radiaux tels que (18), (181) qui rayonnent à partir d'un trou axial (19) aboutissant à un joint tournant (20) dont la partie fixe est reliée à un tuyau d'air comprimé (21). Le haut des trous verticaux (16) débouche sur le flanc supérieur du moyeu de la roue (8) et, lorsqu'il n'est pas obturé, l'air comprimé passant dans chaque venturi (17) provoque du vide dans la ventouse (14).The machine of the invention selects bottles brought by the conveyor (1) according to the arrows (2, 3), and evacuated by the conveyors (4) and (5) according to the arrows (6, 7). The selection is made by a wheel (8) with a vertical axis (9) rotating in a bearing (10) comprising bearings (11, 12). The wheel (8) has cells such as (13) corresponding to the vertical bottles. At the bottom of each cell such as ( 1 3), is arranged a suction cup such as (14) made of elastic material. Each suction cup (14) is screwed by a nozzle ( 1 5) into the wheel hub (8) and has a hole coaxial with the suction cup (14) which opens into a vertical hole ( 1 6) corresponding to the bottom of each cell (13). In fact each suction cup (14) is connected to the part of small section of a venturi (17) placed in the hole (16). The hole (16) receives, at its lower part, compressed air from radial holes such as (18), (181) which radiate from an axial hole (19) leading to a rotary joint (20 ) whose the fixed part is connected to a compressed air pipe (21). The top of the vertical holes (16) opens onto the upper flank of the wheel hub (8) and, when it is not closed, the compressed air passing through each venturi (17) causes vacuum in the suction cup ( 14).
Ce vide peut être cassé par un obturateur mobile (22) ou fixe (23).This vacuum can be broken by a movable (22) or fixed (23) shutter.
L'obturateur fixe (23) obture automatiquement le haut des trous (16) quand ceux-ci viennent glisser contre sa partie inférieure.The fixed shutter (23) automatically closes the top of the holes (16) when they slide against its lower part.
L'obturateur (22) en fait de même lorsque sa partie inférieure (24) est au niveau de la partie supérieure du trou (16). Cependant, la platine (24) peut être soulevée dar6le sens de la flèche (25) à partir d'un vérin (non représenté) qui soulève l'obturateur (22) en le faisant coulisser dans des glissières verticales appropriées. A ce moment, l'obturateur n'a plus aucun effet et le vide est "cassé" dans la ventouse (14) correspondante. Les obturateurs (22) et (23) sont vissés sur le boitier de palier (10) à des emplacements angulaires déterminés par l'endroit où l'on veut faire la sélection et à une hauteur qui est réglable pour assurer le bon fonctionnement.The shutter (22) does the same when the lower portion (2 4) is at the top of the hole (16). However, the plate (24) can be lifted in the direction of the arrow (25) from a jack (not shown) which lifts the shutter (22) by sliding it in appropriate vertical slides. At this time, the shutter has no effect and the vacuum is "broken" in the corresponding suction cup (14). The shutters (22) and (23) are screwed onto the bearing housing (10) at angular locations determined by the place where one wishes to make the selection and at a height which is adjustable to ensure correct operation.
L'action du vérin à double effet commandant le mouvement des obturateurs (22) se fait automatiquement à l'aide d'une électrovanne qui est commandée, à partir de courants forts émis dans un boitier de commande qui reçoit des signaux lumineux venant d'un détecteur qui est représenté schématiquement à la figure 4. En fait, il existe au moins deux détecteurs l'un supérieur (26) et l'autre inférieur (27) qui comprend chacun deux groupes de fibres optiques l'un amenant un rayonnement lumineux (28) l'autre ramenant le rayonnement réfléchi éventuel (29). Ces deux couples de fibres optiques sont repérés par (281) et (291) dans le détecteur (27). Si la lumière émanant de la fibre (28) se dissipe dans le vide suivant le rayon (30), il n'y a aucun rayon ramené par la fibre (29). Si la lumière émise par la fibre (281) suivant le rayon (31) est réfléchie par le goulot (33) de la bouteille pour revenir suivant le rayon (32) dans le fibre (291), une cellule photosensible, située dans le boîtier électrique à l'autre extrémité de la fibre, détermine un courant qui est envoyé à un ampli- ficateur de manière à produire un courant fort qui sera utilisé dans l'électrovanne de commande de l'obturateur mobile (22).The action of the double-acting cylinder controlling the movement of the shutters (22) is done automatically using a solenoid valve which is controlled, from strong currents emitted in a control box which receives light signals coming from a detector which is shown schematically in Figure 4. In fact, it there are at least two detectors, one upper (26) and the other lower (27), each comprising two groups of optical fibers, one bringing in light radiation (28) the other bringing back any reflected radiation ( 2 9) . These two optical fiber pairs are indicated by (281) and (291) in the sensor (2 7). If the light emanating from the fiber (28) dissipates in a vacuum along the ray (30), there is no ray brought back by the fiber (29). If the light emitted from the fiber (2 81) along the radius (31) is reflected by the neck (33) of the bottle to return along the radius (32) in the fiber (291), a photosensitive cell, located in the at the other end of the fiber junction box, determines a current that is supplied to a f icateur amplified to produce a strong current that will be used in the control solenoid of the movable shutter (22).
Le boitier du palier (10) comporte des facettes (34, 35, 36) destinées à y fixer soit les obturateurs (22) ou (23), soit un support (37) ou (38) comportant un axe tel que (39) que l'on peut bloquer dans une chape (40) fixée au bout d'un bras mobile (41) que l'on peut aussi bloquer dans une chape (42) solidaire du bâti de la machine.The bearing housing ( 1 0) has facets (34, 35, 36) intended to fix there either the shutters (22) or (23), or a support (37) or (38) having an axis such as (39 ) that can be blocked in a yoke (40) fixed to the end of a movable arm (41) that can also be blocked in a yoke (42) secured to the frame of the machine.
Les transporteurs (4) et (5) sont du type à chaîne avec des patins plans et sont évidemment bordés de guides latéraux schématisés par les traits (43). Le transporteur (1) amène les bouteilles suivant les flèches (2) et (3) qui sont ainsi poussées dans chacun des alvéoles (13), aidés en cela par la lame élastique (44) qui pousse bien à fond la bouteille contre la ventouse (14) correspon- dante. Cette ventouse, dans chacun des alvéoles tournés du côté du transporteur (1), est toujours dans le stade d'aspiration puisqu'il n'y a aucun obturateur dans ce secteur. Dans le secteur de la roue (8) où se trouve l'obtu- rateur (22), celui-ci, suivant les indications de détecteurs (26) et (27), casse le vide dans la ventouse correspondant, auquel cas la bouteille prend le chemin du transporteur (4) suivant la flèche (6), on ne casse pas ledit vide, auquel cas, la bouteille est entraînée par la roue (8) Jusque dans le secteur de l'obturateur (23) qui casse le vide, ce qui a pour effet de placer la bouteille correspondant en face du transporteur (5) pour qu'elle s'évacue suivant la flèche (7).The conveyors (4) and (5) are of the chain type with flat shoes and are obviously bordered by lateral guides shown diagrammatically by the lines (43). The conveyor (1) brings the bottles along the arrows (2) and (3) which are thus pushed into each of the cells (13), helped in this by the elastic blade (44) which pushes although thoroughly the bottle against the sucker (14) corresponding to ante. This suction cup, in each of the cells turned on the side of the conveyor (1), is still in the suction stage since there is no shutter in this sector. In the sector of the wheel (8) where the obtu- r at e ur location (22) thereof, following the indications of sensors (26) and (27), the vacuum breaker in the corresponding suction cup, in which case the bottle takes the path of the transporter (4) according to the arrow (6), said vacuum is not broken, in which case, the bottle is driven by the wheel (8) Up to the shutter sector (23) which breaks the vacuum, which has the effect of placing the corresponding bottle in front of the conveyor (5) so that it is evacuated along the arrow (7).
Pour obtenir ce résultat, il est évidemment indispensable que l'appareil soit correctement réglé et cela est facilité par l'orientation donnée au bras (41) et au support (37) ou (38). Il faut aussi que les transporteurs (4) et (5) soient convenablement disposés l'un par rapport à l'autre et ensemble par rapport à la roue (8).To obtain this result, it is obviously essential that the device is correctly adjusted and this is facilitated by the orientation given to the arm (41) and to the support (37) or (38). It is also necessary that the conveying e cores (4) and (5) are suitably arranged relative to each other and all relative to the wheel (8).
On pourrait immaginer un troisième transporteur situé entre les deux transporteurs (4) et (5), à l'endroit des guides (45) et qui soit alimenté par une action temporisée de l'obturateur (22) à partir de l'un des deux détecteurs (26) ou (27) pour que le vide soit cassé afin que la bouteille correspondante soit lâchée dans un secteur qui corresponde a l'emplacement du dit troisième transporteur d'évacuation.We could immaginer had a third transport r between the two carriers (4) and (5) at the location of the guides (45) and is powered by a timed action of the shutter (22) from the one of the two detectors (26) or (27) so that the vacuum is broken so that the corresponding bottle is released in an area which corresponds to the location of said third evacuation conveyor.
Il faut bien comprendre que, par rapport aux dispositifs existants, il n'y a aucun dispositif de commande d'entraînement de la roue (8) : celle-ci est entrainèe dans le sens de la flèche (46) par le mouvement des bouteilles déplacées par le transporteur (1) dans le sens des flèches (2) et (3).It must be understood that, compared to existing devices, there is no drive control device for the wheel (8): the latter is driven in the direction of the arrow ( 4 6) by the movement of the bottles displaced by the conveyor ( 1 ) in the direction of the arrows (2) and (3).
Il faut aussi comprendre que la machine de l'invention peut fonctionner aussi avec une pompe'à vide, auquel cas on mettrait un obturateur fixe sur tout le dessous du boiter du palier (10) sauf aux endroits où il y a les deux obturateurs (22) et (23). A la place de l'obturateur (23) il n'y aurait rien. A la place de l'obturateur (22) il y aurait un obturateur mobile qui agirait à l'opposé de l'obturateur (22) qui a été décrit, c'est-à-dire qui se lèverait pour laisser partir les bouteilles dans le transporteur (4) et qui s'abaisserait pour les entraîner Jusqu'au transporteur (7), ce qui est l'inverse de ce qui a été décrit ci-dessus. Les avantages seraient les mêmes Puisqu'il n'y a aucun organe mobile de sélection sur ou dans la roue (8).It should also be understood that the machine of the invention can also operate with a vacuum pump, in which case a fixed shutter would be placed on the entire underside of the bearing housing (10) except in the places where there are the two shutters ( 22) and (23). In place of the shutter (23) there would be nothing. In place of the shutter (22) there would be a movable shutter which would act opposite the shutter (22) which has been described, that is to say which would rise to let the bottles leave in the transporter (4) and which would lower to drive them to the transporter (7), which is the reverse of what has been described above. The advantages would be the same Since there is no movable selection member on or in the wheel (8).
