MEMORIA DESCRIPTIVA DESCRIPTIVE MEMORY
La presente invención se relaciona con un equipo para el movimiento de productos, mercancías, mercaderías o cargas, y más específicamente se refiere a un equipo para mover productos o cargas paletizadas (en pallets) depositada sobre láminas deslizantes (slip sheet), el que es capaz de recuperar dicha lámina deslizante para su reutilización, concentrando en un solo equipo las funciones de tomar el cargamento, dejar el cargamento, empujar el cargamento y retener la lámina deslizante.  The present invention relates to equipment for the movement of products, merchandise, merchandise or cargo, and more specifically refers to equipment for moving products or palletized loads (on pallets) deposited on sliding sheets, which is capable of recovering said sliding sheet for reuse, concentrating on a single device the functions of taking the cargo, leaving the cargo, pushing the cargo and retaining the sliding sheet.
DESCRIPCION DEL ARTE PREVIO DESCRIPTION OF PRIOR ART
En el campo de carga de mercaderías paletizadas, se han desarrollado varias soluciones relacionadas con el movimiento de ellas dependiendo de los contextos o necesidades surgidas. La presente invención se sitúa específicamente en el campo del movimiento de mercadería paletizada dispuesta sobre láminas deslizantes dado que se quiere evitar el uso del pallet debido a que ocupa espacio en desmedro de la carga y tiene un valor monetario mayor con respecto a la lámina deslizante.  In the field of loading palletized goods, several solutions related to their movement have been developed depending on the contexts or needs that have arisen. The present invention is specifically located in the field of movement of palletized merchandise arranged on sliding sheets since it is desired to avoid the use of the pallet because it occupies space at the expense of the load and has a greater monetary value with respect to the sliding sheet.
Algunas de las soluciones que se han desarrollado consisten en grúas horquillas, que a través de brazos planos y paralelos, mueven la mercadería en sentido vertical y se desplazan en el plano horizontal. Las grúas horquillas son equipos pesados, porque tienen que compensar el i peso sostenido en sus horquillas con carga adicional en su parte trasera. Algunas de ellas se pueden apreciar en las patentes de Estados Unidos números US 3.933.224 y US 3.721.318. La limitación que esta solución posee, es que cuando se ocupan horquillas estándar no es capaz de tomar la mercadería desde nivel de piso, sólo es posible hacerlo si ésta está sobre un pallet; de manera equivalente, tampoco posee la facultad de dejar la mercadería en posición de apilamiento si no está sobre un pallet. Some of the solutions that have been developed consist of fork cranes, which move the goods vertically and move in the horizontal plane through flat and parallel arms. Fork cranes are heavy equipment, because they have to compensate for the i weight held on its forks with additional load on its rear. Some of them can be seen in U.S. Patent Nos. 3,933,224 and 3,721,318. The limitation that this solution has, is that when standard forks are occupied it is not able to take the merchandise from floor level, it is only possible to do it if it is on a pallet; Similarly, it does not have the power to leave the merchandise in a stacking position if it is not on a pallet.
Para resolver el problema anterior se creó un sistema que utiliza un pantógrafo en conjunto con una hoja deslizante, el cual permite por un lado, empujar el bulto hacia fuera para su descarga, y por otro lado, también permite tirar atrayendo el bulto hacia la grúa o máquina para cargarlo sobre las horquillas. Esta solución es especialmente útil cuando se opera sin palléis, de modo que esto permite prescindir de ellos en los espacios de carga.  To solve the previous problem, a system was created that uses a pantograph in conjunction with a sliding blade, which allows, on the one hand, to push the package outwards for unloading, and on the other hand, it also allows pulling by pulling the package towards the crane or machine to load it on the forks. This solution is especially useful when operating without pallets, so this allows them to be dispensed with in cargo spaces.
Este tipo de soluciones recién descritas derivan en los sistemas de carga de tira-empuje, mejor conocidos en el rubro como sistemas "push-pull", consistentes en un mecanismo del tipo pantógrafo accionado generalmente por actuadores lineales. En él la mercadería es montada sobre una plataforma lisa que se dispone sobre de las horquillas de la grúa o reemplazándolas por horquillas de mayor superficie, tal como se puede apreciar, por ejemplo, en la patente norteamericana US 4.752.179; esto permite que la carga dispuesta en láminas deslizantes sea deslizada sobre las paletas o plataformas.. This type of solutions just described derive in the push-pull load systems, better known in the field as "push-pull" systems, consisting of a pantograph type mechanism generally actuated by linear actuators. In it, the merchandise is mounted on a flat platform that is disposed on the fork of the crane or replacing them with forks of greater surface area, as can be seen, for example, in US Patent 4,752,179; This allows the load arranged on sliding plates to be slid on the pallets or platforms.
Como se ha señalado, junto con las plataformas mencionadas se usan láminas deslizantes (en el rubro se conocen como "slip sheets"), que tiene un costo apreciablemente menor que un pallet y prácticamente no ocupa espacio en el contenedor, eliminando también los problemas ambientales y de reciclaje.  As noted, along with the platforms mentioned, sliding sheets are used (in the area they are known as "slip sheets"), which has a significantly lower cost than a pallet and practically does not take up space in the container, also eliminating environmental problems and recycling.
Las láminas deslizantes están normalmente fabricadas de alguna fibra sólida o plástico y poseen una dimensión superior al perímetro de la mercadería o bulto, de modo que sus bordes sobresalen de la mercadería o bulto. Con este mecanismo de push-pull unido a la grúa horquilla, se consigue mover la mercadería tanto en sentido vertical, propio de la operación de la grúa, como también en un plano horizontal, a través del movimiento de empuje o tracción de pantógrafo, tal como se puede ver en las patentes US 2.601.932, US 3.516.641, y US 5.316.433. The sliding sheets are normally made of some solid fiber or plastic and have a dimension greater than the perimeter of the merchandise or bulk, so that its edges protrude from the merchandise or bulk. With this push-pull mechanism attached to the forklift, the goods can be moved both vertically, typical of the operation of the crane, as well as in a horizontal plane, through the movement of pushing or pulling pantographs, such as can be seen in patents US 2,601,932, US 3,516,641, and US 5,316,433.
Otro ejemplo de uso de push-pull con láminas deslizantes se aprecian en las patentes US 4.300.867 y US 5.769.595 donde, en este caso se ven transpaletas a las que se les ha adaptado un sistema de push-pull y un medio de inclinación de una plataforma, de modo que con dicha inclinación, el equipo pueda tomar la mercadería depositada en una lámina deslizante desde el nivel de piso o que bien que esté sobre un pallet. Another example of the use of push-pull with sliding blades can be seen in patents US 4,300,867 and US 5,769,595 where, in this case, pallet trucks are seen to which a push-pull system and a means of tilt of a platform, so that with this inclination, the team can take the merchandise deposited on a sliding sheet from the floor level or that it is on a pallet.
En operación, y dado que las láminas deslizantes (slip sheet) sobresalen desde los bordes del bulto -o mercadería- el sistema push-pull cuenta con un mecanismo de mordaza en su extremo anterior, el que muerde o atrapa el borde sobresaliente de la lámina deslizante (slip sheet) y así es capaz de arrastrar atrayendo la mercadería y ponerla sobre la plataforma lisa. No lo hace levantando desde abajo como cuando se usa pallet, sino que la arrastra deslizándola y tirándola por el slip sheet. En oposición, cuando el bulto ha de ser descargado, es empujado hacia fuera gracias al estiramiento del mecanismo de pantógrafo. In operation, and since the sliding sheets (slip sheet) protrude from the edges of the package - or merchandise - the push-pull system has a jaw mechanism at its front end, which bites or catches the protruding edge of the sheet (slip sheet) and thus is able to drag attracting the goods and put it on the flat platform. It does not lift from below as when using pallet, but drag it by sliding and pulling it by the slip sheet. In opposition, when the package is to be unloaded, it is pushed out thanks to the stretching of the pantograph mechanism.
En la solución del problema de tomar la mercadería se han desarrollado otras alternativas, tal como la incorporación de un sistema de rodado en las mismas horquillas de la grúa, llamado en el rubro como "Roller-fork", la que se puede apreciar por ejemplo en la patente norteamericana US 7.435.047, donde se ve como un conjunto de rodillos, rodamientos o ruedas dispuestas a lo largo de cada horquilla conformando una superficie de rodado, facilitando enormemente el desplazamiento de la mercadería sobre dichas horquillas, tanto en el sentido de carga como de descarga, debiendo colocar idealmente el bulto sobre láminas deslizantes para poder realizar su desplazamiento.  In the solution of the problem of taking the merchandise other alternatives have been developed, such as the incorporation of a rolling system in the same crane forks, called in the heading as "Roller-fork", which can be appreciated for example in US Patent 7,435,047, where it is seen as a set of rollers, bearings or wheels arranged along each fork forming a road surface, greatly facilitating the movement of the merchandise on said forks, both in the sense of loading and unloading, ideally placing the package on sliding plates to be able to move.
En operación, este tipo de equipos de horquillas con sistema de rodado son capaces de tomar y dejar bultos a nivel de piso con mucha eficiencia. La desventaja que este sistema posee es que si bien es capaz de tomar y dejar la mercadería a nivel de piso, no es capaz de tomar la mercadería desde nivel de pallet, tornándose muy engorroso y requiriendo una precisión casi imposible por parte del operario para hacer entrar las horquillas entre la superficie del pallet y la lámina deslizante; como resultado suele pasar que la punta de las horquillas empujan el pallet, moviendo todo el bulto; o se rompe la lámina deslizante. In operation, this type of forklift equipment with rolling system is able to take and leave packages at floor level very efficiently. The disadvantage that this system has is that although it is capable of taking and leaving the merchandise at floor level, it is not able to take the merchandise from the pallet level, becoming very cumbersome and requiring almost impossible precision on the part of the operator to make enter the forks between the surface of the pallet and the sliding blade; as a result, it usually happens that the tip of the forks push the pallet, moving the entire package; or the sliding blade breaks.
Para resolver este problema se ideó un tipo de pallet que se usa exclusivamente con este sistema de horquillas con rodadura, conocido en el rubro como pallet RF (de roller fork). Dichos pallet presentan tacos en su cara superior, y separados entre sí de modo tal que genere espacios para la introducción de las horquillas con rodadura y tomar la mercadería que está con o sin láminas deslizantes.  To solve this problem, a type of pallet was devised that is used exclusively with this rolling fork system, known in the area as RF pallet (roller fork). These pallets have studs on their upper face, and separated from each other in a way that generates spaces for the introduction of the forks with rolling and take the merchandise that is with or without sliding blades.
El sistema roller-fork o de horquillas con rodaduras posee el inconveniente de que si se desea rescatar la lámina deslizante (slip sheet), éste no lo permite, es decir, al depositar la mercadería ya sea a piso o a pallet, la lámina necesariamente se va con la mercadería, dado que no hay ningún mecanismo que la retenga.  The roller-fork or roller fork system has the disadvantage that if it is desired to rescue the sliding sheet (slip sheet), it does not allow it, that is, when depositing the merchandise either on the floor or on the pallet, the sheet is necessarily It goes with the merchandise, since there is no mechanism to retain it.
Otro aparato que se ha desarrollado para el trabajo en este campo, es un sistema que reúne horquillas convencionales y el mecanismo de push-pull para empuje de la mercadería con o sin lámina deslizante. Este equipo se conoce en el rubro como "push-load" y no es capaz de tomar tirando o arrastrando la mercadería. El equipo toma la mercadería desde pallet, claro que siempre que dicho pallet posea algunos tacos espaciadores, tal como el ya mencionado pallet RP, de modo que toma la mercadería desde abajo, igual que una horquilla convencional y para descarga, lo empuja hacia fuera extendiéndose el sistema de pantógrafo. Eventualmente la mercadería podría ir sobre una hoja deslizante.  Another device that has been developed for work in this field, is a system that brings together conventional forks and the push-pull mechanism for pushing the merchandise with or without sliding blade. This equipment is known in the area as "push-load" and is not able to take by pulling or dragging the merchandise. The team takes the merchandise from the pallet, of course, whenever the pallet has some spacer blocks, such as the aforementioned RP pallet, so that it takes the merchandise from below, just like a conventional fork and for unloading, it pushes it out extending The pantograph system. Eventually the merchandise could go on a sliding sheet.
En el arte previo existen mecanismos de push-pull con retención de lámina deslizante, no obstante, presentan inconvenientes en su velocidad de operación y de costos. El problema técnico que se suscita es que si el objetivo es poder mover mercaderías prescindiendo del pallet y recuperando el slip sheet para su reutilización a una velocidad de operación razonable, ninguno de los sistemas hasta ahora desarrollados permite eso; detallando, si bien el sistema de horquillas con sistema de rodado (llamado roller-fork) permite tomar y dejar mercadería manejada en slip sheet, este sistema no permite retener el slip sheet. Por otro lado, el sistema llamado "push-load" que reúne horquillas y mecanismo de pantógrafo, permite tomar bultos desde pallet RF, con slip sheet y en el momento de la descarga, éste la deja o deposita valiéndose del pantógrafo en despliegue para empujar el bulto hacia afuera, pero el slip sheet se desliza igualmente con el bulto y por lo tanto, tampoco permite retener la lámina para su recuperación y reutilización. In the prior art there are push-pull mechanisms with slide-leaf retention, however, they present inconveniences in their operating speed and costs. The technical problem that arises is that if the objective is to be able to move merchandise without the pallet and recovering the slip sheet for reuse at a reasonable operating speed, none of the systems developed so far allows that; detailing, although the fork system with rolling system (called roller-fork) allows to take and leave merchandise handled in slip sheet, this system does not allow to retain the slip sheet. On the other hand, the system called "push-load" that combines forks and pantograph mechanism, allows you to take packages from RF pallet, with slip sheet and at the time of unloading, it leaves or deposits using the pantograph in deployment to push the package outward, but the slip sheet slides equally with the package and therefore does not allow the sheet to be retained for recovery and reuse.
El sistema de plataforma con push-pull sería el sistema más adecuado que hasta ahora se conoce que permitiría mover mercaderías sin pallet y con slip sheet, ya que si bien los tres sistemas descritos con anterioridad permiten dejar la mercadería tanto a piso como a pallet, este sistema de push-pull, a diferencia de los otros dos sistemas -horquillas con rodadura (roller-fork) y horquillas con pantógrafo (push-load)- permite tomar tanto de piso como de pallet convencionales, en cambio los otros equipos permiten tomar de piso o de un pallet con tacos espaciadores (pallet RF), y no de pallet convencionales, hecho que limita su aplicación al requerir un accesorio de carga especial.  The push-pull platform system would be the most appropriate system known so far that would allow moving merchandise without pallet and with slip sheet, since although the three systems described above allow the merchandise to be left both on the floor and on the pallet, This push-pull system, unlike the other two systems - rolling fork (roller-fork) and fork with pantograph (push-load) - allows you to take both conventional floor and pallet, instead the other equipment allows you to take of floor or of a pallet with spacers (RF pallet), and not of conventional pallets, a fact that limits its application by requiring a special load accessory.
El gran inconveniente o desventaja del sistema de carga push-pull es que su proceso de operación es muy lento en comparación con la rapidez que se logra por ejemplo, con el sistema de roller-fork, donde las horquillas con sistema de rodado permiten tomar y dejar mercadería con slip sheet a una velocidad muy superior, derivando en un importante ahorro de recursos, principalmente tiempo-dinero. Súmese a ello que el sistema push-pull requiere de mayor energía para operar, dado que para subir la mercadería hacia la plataforma lisa lo hace tirando/atrayendo el bulto depositado en el slip sheet gracias al mecanismo de pantógrafo que funciona con una serie de actuadores lineales. Finalmente, el sistema push-pull es en sí un equipo mucho más complejo en su conformación. The great disadvantage or disadvantage of the push-pull loading system is that its operation process is very slow compared to the speed that is achieved, for example, with the roller-fork system, where the forks with a rolling system allow taking and leave merchandise with slip sheet at a much higher speed, resulting in significant savings of resources, mainly time-money. Add to this that the push-pull system requires more energy to operate, since to raise the merchandise to the smooth platform it does so by pulling / attracting the bulk deposited on the slip sheet thanks to the pantograph mechanism that It works with a series of linear actuators. Finally, the push-pull system is itself a much more complex team in its conformation.
Tal como se manifestó anteriormente, cuando los requerimientos de trabajo son los de mover mercadería con slip sheet, prescindiendo de pallet, ya se obtiene una ventaja por sobre lo existente, dado que disminuyen ostensiblemente los costos de operación al usar sólo las láminas deslizantes (slip sheet) en el proceso de descarga; pero dicha ventaja se vería aún más acrecentada si toda la operación permitiera recuperar las láminas deslizantes (slip sheet) para su reutilización, consiguiendo con ello un ahorro de recursos de todo tipo, entre otros, económicos y medioambientales, al no tener que ocupar siempre láminas nuevas para el movimiento de los bultos, ya que de acuerdo a los procesos de descarga que permite la actual tecnología las láminas se pierden porque se quedan en el punto de descarga al no poder sacarlas bajo los bultos en el mismo momento en que se realiza la descarga.  As stated earlier, when the work requirements are those of moving merchandise with slip sheet, regardless of pallet, an advantage is already obtained over what exists, since the operating costs are significantly reduced when using only the sliding sheets (slip sheet) in the download process; but this advantage would be even more accentuated if the entire operation allowed to recover the sliding sheets (slip sheet) for reuse, thereby saving resources of all kinds, among others, economic and environmental, by not always having to occupy sheets new for the movement of the packages, since according to the downloading processes that the current technology allows, the sheets are lost because they remain at the point of discharge as they cannot be removed under the packages at the same time when the discharge.
La presente invención apunta a mejorar el manejo de descarga de bultos que se movilizan en slip sheet, prescindiendo de pallets, a través de un equipo que permite una operación rápida, que es más simple y eficiente que el sistema de push-pull y que principalmente es capaz de retener la lámina deslizante en el proceso de descarga, de modo que es posible su recuperación para la reutilización. The present invention aims to improve the handling of unloading packages that move in slip sheet, without pallets, through a device that allows a fast operation, which is simpler and more efficient than the push-pull system and that mainly It is able to retain the sliding sheet in the unloading process, so that its recovery is possible for reuse.
