SYSTEME DE CHARGEMENT DE PAPIERPAPER LOADING SYSTEM
La présente invention concerne un système de chargement, à la marge de presses offset en particulier de presses offset de petit et moyen format, d'un support d'impression présenté sous forme de feuilles conditionnées en palette cube et un procédé de chargement utilisant le système. Une palette cube est constituée de deux piles de feuilles lorsqu'il s'agit de papier destiné à une presse moyen format et de quatre piles lorsqu'il s'agit de papier destiné à une presse petit format: piles d'égale hauteur, accolées et disposées sur une palette. La palette cube est en général emballée et maintenue par un film en matière plastique. The present invention relates to a loading system, at the margin of offset presses in particular of small and medium format offset presses, a printing medium presented in the form of sheets packaged in a cubic pallet and a loading method using the system. . A cube pallet consists of two stacks of sheets when it comes to paper intended for a medium format press and four stacks when it is paper intended for a small press: stacks of equal height, contiguous and arranged on a pallet. The cube pallet is usually packaged and held by a plastic film.
Traditionnellement, le chargement des feuilles se fait manuellement par transfert d'une partie de la pile de feuilles de la palette cube vers le plateau de marge de la machine offset. Ce chargement manuel nécessite du temps et représente un travail physique pénible. Le but de l'invention est de proposer un procédé de chargement rapide et ne nécessitant aucun effort physique. Traditionally, sheets are loaded manually by transferring a portion of the stack of sheets from the cube pallet to the margin tray of the offset machine. This manual loading requires time and is a painful physical job. The object of the invention is to provide a fast charging method and requiring no physical effort.
Le procédé de chargement de la présente invention consiste à : - Placer sur une palette cube deux plateaux mobiles munis de roues, les roues étant positionnées vers le haut, - Retourner la palette à l'aide d'un retourneur de palette, - Séparer les 2 piles, - Introduire une pile dans les créneaux d'un plateau porteur s'adaptant à la marge de la machine et - Insérer une barre de renfort dans la partie arrière du plateau porteur de manière à lui redonner la rigidité nécessaire pour supporter le poids de la pile de support d'impression. The loading method of the present invention consists in: placing on a cubic pallet two movable trays equipped with wheels, the wheels being positioned upwards, turning the pallet with a pallet turner, separating them 2 batteries, - Insert a battery into the slots of a carrier plate that fits the machine's margin and - Insert a reinforcing bar into the back of the carrier plate to give it the rigidity needed to support the weight of the print media stack.
On a déjà cherché à simplifier le chargement des supports d'impression dans les presses offset. Par exemple, le brevet US5404817 décrit un chariot pour le préchargement du papier dans une presse offset, le chariot comportant au moins trois roues. We have already sought to simplify the loading of printing media in offset presses. For example, US5404817 discloses a carriage for preloading paper in an offset press, the carriage having at least three wheels.
De très nombreux documents concernent des dispositifs pour retourner des objets, telles que des piles de papier, par exemple les brevets US3670903, US4498841 et US5209629. Numerous documents relate to devices for returning objects, such as stacks of paper, for example US Pat. No. 3,670,903, US Pat. No. 4,989,441 and US Pat.
Cependant, aucun document ne décrit un système de chargement de papier analogue à celui de la présente invention. However, no document describes a paper loading system similar to that of the present invention.
Ce système est caractérisé par l'utilisation: - d'un plateau porteur (1) remplaçant le plateau de marge d'origine de la presse offset; ce plateau porteur (1) comporte 2 découpes en forme de créneau permettant le passage des plateaux mobiles, - de 2 plateaux mobiles (2), - d'une barre de renfort (3) et - éventuellement d'une planche de soutien utilisée 20 dans le cas où la palette ne comporte pas ou ne comporte plus d'emballage plastique. This system is characterized by the use of: - a carrier plate (1) replacing the original margin plate of the offset press; this carrier plate (1) comprises 2 slots in the form of crenel for the passage of mobile trays, - 2 movable trays (2), - a reinforcement bar (3) and - possibly a support board used 20 in the case where the pallet does not include or no longer contains plastic packaging.
Le dessin annexé permet d'illustrer plus en détail la présente invention. The accompanying drawing illustrates the present invention in more detail.
Sur la figure 1 sont représentés le plateau porteur (1), un plateau mobile (2) et la barre de renfort (3). In Figure 1 are shown the carrier plate (1), a movable platen (2) and the reinforcing bar (3).
Le plateau porteur (1) s'adapte à la marge de la machine. Il a les mêmes dimensions que le plateau de marge d'origine, qu'il remplace lors de l'utilisation du système, et la forme de sa partie avant est telle que son adaptation à la marge de la machine soit optimale. Le plateau porteur (1) est caractérisé par deux découpes (4) en forme de créneau. Ces découpes transversales permettent le passage des roues du plateau mobile (2) et elles définissent des parties saillantes (5a), (5b) et (5c). The carrier plate (1) adapts to the margin of the machine. It has the same dimensions as the original margin plate, which it replaces when using the system, and the shape of its front part is such that its adaptation to the margin of the machine is optimal. The carrier plate (1) is characterized by two cutouts (4) in the form of a crenel. These transverse cuts allow the wheels of the movable plate (2) to pass and define projecting parts (5a), (5b) and (5c).
Le plateau mobile (2) est un plateau quelconque au format du support d'impression le plus souvent utilisé. Chaque plateau (2) est muni de roues, en général quatre roues. Il s'agit plus particulièrement de roues multidirectionnelles dotées d'un système de frein ou de blocage. Lors du chargement, le plateau mobile (2) vient se positionner sur]4e plateau porteur (1). Il faut donc que les roues soient placées de manière à permettre une insertion aisée du plateau mobile (2) dans les créneaux du plateau porteur (1). The movable platen (2) is any tray in the format of the print medium most often used. Each tray (2) is provided with wheels, generally four wheels. It is more particularly of multidirectional wheels equipped with a brake or blocking system. During loading, the movable plate (2) is positioned on] 4th carrier plate (1). It is therefore necessary that the wheels are placed so as to allow easy insertion of the movable plate (2) into the slots of the carrier plate (1).
La barre de renfort (3) conçue pour venir s'imbriquer dans la partie arrière du plateau porteur (1) comporte trois trous (6a), (6b) et (6c). Elle redonne à ce dernier la rigidité nécessaire pour supporter le poids des piles de support d'impression de la palette cube. La partie inférieure (7) de la barre de renfort (3) est en saillie. Le plateau porteur (1) vient s'appuyer sur cette partie en saillie (7), ce qui contribue à la rigidité du système. Les portions (5a), (5b) et (5c) de la partie arrière du plateau porteur (1) viennent s'emboîter respectivement dans les trous (6a), (6b) et (6c). L'épaisseur de la barre de renfort (3) est prévue pour permettre le maintien en place du plateau mobile (2). The reinforcement bar (3) designed to fit into the rear portion of the carrier plate (1) has three holes (6a), (6b) and (6c). It restores to the latter the rigidity necessary to support the weight of the printing support stacks of the cube pallet. The lower part (7) of the reinforcing bar (3) is projecting. The carrier plate (1) is supported on this projecting portion (7), which contributes to the rigidity of the system. The portions (5a), (5b) and (5c) of the rear portion of the carrier plate (1) are interlocked respectively in the holes (6a), (6b) and (6c). The thickness of the reinforcement bar (3) is provided to allow the movable platen (2) to be held in place.
Ainsi, en position d'utilisation, le plateau mobile (2) est bloqué vers l'avant par les roues (8) et (8') qui butent sur l'extrémité des découpes (4) du plateau porteur (1) et vers l'arrière par la barre de renfort (3). En outre le poids de la pile de papier empêche le plateau mobile de bouger une fois levé. Thus, in the position of use, the movable plate (2) is blocked forward by the wheels (8) and (8 ') which abut on the end of the cutouts (4) of the carrier plate (1) and towards the back by the reinforcement bar (3). In addition, the weight of the paper stack prevents the movable platter from moving when raised.
Le système de chargement de la présente invention, nécessite l'utilisation d'un système retourneur de palette. Le système retourneur de palette utilisé dans la présente invention n'est pas critique, il s'agit de n'importe quel système permettant de retourner une palette cube. The loading system of the present invention requires the use of a pallet turning system. The pallet turning system used in the present invention is not critical, it is any system for returning a cube pallet.
Pour charger une machine offset, on amène la palette cube au retourneur de palette. Après avoir retiré la partie supérieure du film en matière plastique recouvrant la palette, on place sur le dessus de la palette les deux plateaux mobiles (2), dans le sens du papier, roues positionnées vers le haut, le système de frein ou de blocage des roues étant enclenché si nécessaire, puis on effectue ensuite le retournement. Après déblocage éventuel des roues, on sépare les deux piles en enlevant la totalité du film en matière plastique qui les maintenait accolées. La séparation des piles peut avoir lieu au niveau du retourneur de palettes, mais il est préférable d'amener ensemble les deux piles au niveau de la presse offset puis de les séparer au plus près de la marge de la machine. On amène une pile reposant sur un des plateaux mobiles (2) jusqu'à la marge de la machine et on introduit ledit plateau mobile (2) dans les découpes (4) du plateau porteur (1) positionné en marge de la machine. On place la barre de renfort (3) à l'arrière du plateau porteur (1) en insérant lés parties saillantes (5a), (5b) et (5c) de la découpe arrière du plateau porteur (1) respectivement dans les trous (6a), (6b) et (6c) de la barre de renfort (3). La machine offset est ainsi prête à fonctionner. To load an offset machine, bring the cube pallet to the pallet turner. After having removed the upper part of the plastic film covering the pallet, the two movable trays (2) are placed on the top of the pallet, in the direction of the paper, wheels positioned upwards, the brake or blocking system wheels are engaged if necessary, then the reversal is performed. After unlocking the wheels, the two piles are separated by removing all of the plastic film which kept them contiguous. The separation of the batteries can take place at the level of the pallet turner, but it is better to bring the two batteries together at the offset press and then to separate them closer to the margin of the machine. A stack resting on one of the moving plates (2) is brought to the margin of the machine and said movable platen (2) is introduced into the cutouts (4) of the carrier plate (1) positioned in the margin of the machine. The reinforcement bar (3) is placed at the rear of the carrier plate (1) by inserting the protruding parts (5a), (5b) and (5c) of the rear cutout of the carrier plate (1) respectively into the holes ( 6a), (6b) and (6c) of the reinforcing bar (3). The offset machine is thus ready for operation.
De cette manière, on peut charger une pile de 150 kg en moins de trois minutes et une seconde pile est prête à être chargée en un laps de temps encore plus court, sans effort ni fatigue. In this way, a 150 kg battery can be charged in less than three minutes and a second battery is ready to be charged in an even shorter period of time without effort or fatigue.
Lorsque la palette cube n'est pas ou n'est plus emballée dans un film en matière plastique, on utilise une planche de soutien que l'on place audessus des deux plateaux mobiles (2) avant le retournement de la palette. Cette planche de soutien maintient accolées les deux ou quatre piles reposant sur les plateaux (2) pour éviter que les piles ne se séparent les unes des autres ou ne tombent chacune de leur côté. Après retournement des piles, la planche de soutien tombe d'elle-même. La forme de la planche de soutien n'est pas critique. Elle doit présenter une longueur voisine de celle de la palette cube et une largeur suffisante pour maintenir en place les deux piles lors du retournement. When the cube pallet is not or is no longer wrapped in a plastic film, a support board is used which is placed above the two movable trays (2) before turning the pallet. This support board maintains contiguous two or four piles resting on the trays (2) to prevent the batteries from separating from each other or fall each on their side. After turning the batteries upside down, the support board falls on its own. The shape of the support board is not critical. It must have a length close to that of the cube pallet and a width sufficient to hold the two stacks in place during the reversal.
Lorsque l'on enlève le film en matière plastique recouvrant la palette cube, il arrive parfois que le haut des piles ait tendance à présenter un évasement. Pour corriger cet évasement, il peut être utile de prévoir sur le plateau porteur des cales ou plaquettes, de préférence deux, qui améliorent le plaquage du support d'impression contre la marge (mode de réalisation non représenté). Ces cales ou plaquettes sont positionnées entre le plateau porteur et le plateau mobile. Leur épaisseur ne doit pas dépasser 5 mm. When removing the plastic film covering the cube pallet, it sometimes happens that the top of the piles tends to have a flare. To correct this flare, it may be useful to provide on the carrier plate shims or pads, preferably two, which improve the printing of the printing medium against the margin (embodiment not shown). These shims or platelets are positioned between the carrier plate and the movable platen. Their thickness must not exceed 5 mm.
