Abstract

The present invention relates to a vertical elevator with offset load intended to lift from the ground ladles with or without wheels, in order to tip, from various heights, the products contained in these ladles, and which are intended to supply machines. In the present invention, the lifting arm which supports the ladle 8, with or without a wheel, is fastened freely by a chain starwheel, rotating on a needle bearing, on a chain block hoist or winch or any other similar system. The invention is characterised in that the block and tackle of the chain is arranged so that the slack length 14 passes around a return roller 15 secured to the slide in order to exert tension on the latter in the event of jamming during the descent on the one hand, and so as to double the lifting power of the motorisation unit on the other hand. This solution has the effect of increasing the safety of users due to the fact that tension exerted by the slack length prevents any risk of untimely jamming of the slide in the guide column.

Description

La présente invention concerne un élévateur vertical à charge déportee destinéà lever du 601 des cuves avec ou sans roues, pour déverser, à des hauteurs différentes, les produits contenus dans ces cuves et destinés & alimenter des tachines.The present invention relates to a vertical lift with offset load intended to lift from 601 tanks with or without wheels, to dump, at different heights, the products contained in these tanks and intended to feed tachines.

Les élévateurs de ce type existants comprennent un dispositif d'élévation des cuves, avec ou sans roues, constitué par une vis commandée par un moteur, et un écrou fixé dans un coulisseau qui supporte le bras d'elévation, ou une chaine sans fin actionnée par un motoréducteur qui supporte le bras d'élévation, ou un crochet de palan électrique ou treuil qui supporte le bras d'élévation.The existing elevators of this type include a device for elevating the tanks, with or without wheels, constituted by a screw controlled by a motor, and a nut fixed in a slide which supports the elevating arm, or an endless chain operated by a gearmotor which supports the lifting arm, or an electric hoist hook or winch which supports the lifting arm.

Ces trois systèmes ont pour inconvénient un manque de fiabilite occasionné par l'usure de l'écrou ou l'allongement de la chaine qui modifie la tension de celle- ci et des efforts mal maîtrisés qui entrainent une déformation de la colonne au moment du déversement. De plus, dans e cas de l'utilisation d'un palan à chaîne, si, pour une raison ou une autre, le coulisseau se coince dans la colonne de guidage, la chaine va se dérouler librement en ne retenant plus la charge. On comprend les risques encourus par le personnel utilisateur si le coulisseau se décoince et tombe brutalement sans retenue.These three systems have the disadvantage of a lack of reliability caused by the wear of the nut or the elongation of the chain which modifies the tension thereof and poorly controlled forces which cause a deformation of the column at the time of the spill. . In addition, in the case of the use of a chain hoist, if, for one reason or another, the slider gets stuck in the guide column, the chain will unwind freely, no longer retaining the load. We understand the risks run by user personnel if the slider loosens and falls suddenly without restraint.

La présente invention vise a proposer un dispositif qui permettrait d'éviter les inconvénients précédement évoqués. Dans la présente invention, le bras d'elévation qui supporte la cuve, avec ou sans roue. n'est plus solidaire d'un écrou ou bride fixée, sur une chaîne. mais accroche librement par une noixà chaine tournant sur un roulement a aiguilles sur une chaine de palan ou treuil ou tout autre système similaire, dont le soufflage est particulièrement étudié pour éviter les inconvénients prêcénenent évolués.Ceci a pcur avantage d'élever ou de descendre De bras déporté supporte la cuve, avec ou sans roues, librement et directement 5 l'aide -. groupe de motorisation. Le moufflage est effectue de fanon a ce que le brin :cu de la chaine passe autour d'un galet de renvoi solidaire du coulisseau afin d'exercer une traction sur ce dernier au cours de la descente d'une part, et de façon h doubler la puissance de levage du groupe de motorisation d'autre part.Cette solution a pour - effet d'augmenter la fiabilité du fait que le coulisseau est libre dans la colonne de guidage et de glissement, et d'augmenter la sécurité des utilisateurs du fait qu'une traction exercée par le brin mou empeche tout risque de coincement intempestif du coulisseau dans la colonne de guidage.L'élévateur vertical à charge déportiez selon la présente invention, comprend:
Une colonne de glissement et de guidage vertical (1) , un coulisseau (2) sur lequel est fixé solidairement le bras déporté (3) qui supporte la cuve (8).
The present invention aims to provide a device which would avoid the drawbacks mentioned above. In the present invention, the lifting arm which supports the tank, with or without a wheel. is no longer attached to a nut or clamp attached to a chain. but hangs freely by a chain nut rotating on a needle bearing on a chain of hoist or winch or any other similar system, the blowing of which is particularly studied to avoid the disadvantages previously evolved. This has the advantage of raising or lowering offset arm supports the tank, with or without wheels, freely and directly with the aid of. motorization group. The muffling is carried out with a bale that the strand: cu of the chain passes around a deflection roller integral with the slide in order to exert a traction on the latter during the descent on the one hand, and so h double the lifting power of the power unit on the other hand. This solution has the effect of increasing the reliability of the fact that the slide is free in the guide and sliding column, and of increasing the safety of the users of the fact that a traction exerted by the soft strand prevents any risk of inadvertent jamming of the slide in the guide column. The vertical load lift offset according to the present invention, comprises:
A sliding column and vertical guide (1), a slide (2) on which is fixedly the offset arm (3) which supports the tank (8).

Le coulisseau (2) est accroché par une noix & chaîne (7) tournant sur un roulement à aiguilles (13) à une chaine (6) dont le soufflage est effectue de façon à ce que le brin mou (14) passant autour d'un galet de renvoi (15) exerce une traction sur le coulisseau (2) si ce dernier se coince au cours de la descente d'une part, et de façon & doubler la puissance de levage d'autre part.The slide (2) is hooked by a nut & chain (7) rotating on a needle bearing (13) to a chain (6) whose blowing is carried out so that the soft strand (14) passing around a deflection roller (15) exerts traction on the slider (2) if the latter gets stuck during the descent on the one hand, and so as to double the lifting power on the other hand.

Le coulisseau (2) comprend des patins de glissement (4) qui peuvent etre changés facilement quand ils sont usés. La chaîne (6) qui a son point fixe supérieur attaché à la colonne par l'intermédiaire d'un support (9) , descend ensuite et passe autour de la noix à chaîne (7) , remonte et passe autour de la noix à chaîne motrice (18) clavetée sur l'arbre d'entraînement (19). L'arbre d'entrainement (19) est supporte d'un coté par un palier (20) et de l'autre coté par l'arbre creux du motoréducteur-frein (5) dans lequel il est claveté.La chaine descend ensuite vers le galet inférieur (17), passe autour, remonte vers
e galet de renvoi (5). passe autour. et redescend vers son point fixe inférieur attache à a colonne par un support (16) réglable afin d'ajuster la ten--on. Les re--or :1:) et la came de déversement (10), solidaires entre eux, sont fixés sur la colonne (1) par l'intermédiaire de goujons (12) réglables en fonction de la hauteur déterminée pour assurer le déversement du contenu des cuves ou chariots, ce qui permet de contrôler les déformations de la colonne & ce niveau.
The slide (2) includes sliding shoes (4) which can be changed easily when they are worn. The chain (6) which has its upper fixed point attached to the column by means of a support (9), then descends and passes around the chain nut (7), goes up and passes around the chain nut drive (18) keyed onto the drive shaft (19). The drive shaft (19) is supported on one side by a bearing (20) and on the other side by the hollow shaft of the brake gear motor (5) in which it is keyed in. The chain then descends towards the lower roller (17), goes around, goes up towards
e idler roller (5). going around. and descends to its lower fixed point attached to the column by an adjustable support (16) in order to adjust the ten - on. The re-or: 1 :) and the discharge cam (10), integral with each other, are fixed to the column (1) by means of studs (12) adjustable according to the height determined to ensure the discharge of the contents of the tanks or trolleys, which makes it possible to control the deformations of the column at this level.

L'invention est susceptible d'application industrielle notamment dans les industries alimentaires, où l'utilisation d'élévateurs verticaux a charge déportée pour l'alimentaticn des machines est très courante. The invention is susceptible of industrial application in particular in the food industries, where the use of vertical elevators with offset load for the feeding of machines is very common.
