OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención se refiere a un dispositivo para retractilar manualmente, consistente en una barra que presenta en sus extremos una rueda y una empuñadura giratorias y en su zona intermedia unos medios para la inmovilización sobre aquélla de la bobina portadora de la lámina plástica empleada para el retractilado.The present invention relates to a device for manually retracting, consisting of a bar that has at its ends a rotating wheel and handle and in its intermediate zone means for immobilization on that of the reel carrying the plastic sheet used for the shrink wrapping.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Actualmente para mantener unidas varias cajas contenedoras de producto, especialmente cuando se encuentran paletizadas, se envuelve el conjunto de las mismas con una lámina fina de material plástico procedente de una bobina o carrete; conociéndose esta operación como retractilado.Currently, to keep several product container boxes together, especially when they are palletized, they are wrapped with a thin sheet of plastic material from a reel or reel; this operation being known as shrink wrapping.
Este retractilado se puede realizar bien manualmente o bien mediante una máquina provista de una plataforma sobre la que posicionan los productos a retractilar, incluso con el palet correspondiente, y de una bobina contenedora de la lámina plástica. En estas máquinas bien gira la bobina en torno a la plataforma, manteniéndose ésta estática o bien gira la plataforma manteniéndose la bobina en una posición fija. Dichas máquinas permiten realizar el retractilado de forma rápida y sencilla pero tienen un coste elevado, por lo que solo resultan rentables en aquellas empresas en las que el volumen de productos o mercancías a retractilar es elevado.This shrink wrapping can be done either manually or by means of a machine provided with a platform on which the products to be retracted are positioned, even with the corresponding pallet, and of a reel containing the plastic sheet. In these machines, the coil rotates around the platform, keeping it static or the platform rotates, keeping the coil in a fixed position. These machines allow shrink wrapping quickly and easily but have a high cost, so they are only profitable in those companies where the volume of products or merchandise to shrink is high.
Cuando el volumen de productos a retractilar es reducido esta operación se realiza unos dispositivos accionables manualmente y que facilitan básicamente el agarre de la bobina de lámina plástica.When the volume of products to shrink is reduced this operation is performed manually operated devices that basically facilitate the plastic sheet coil grip.
Los dispositivos manuales empleados actualmente, y que guardan una mayor relación con el que es objeto de esta invención, constan de unas empuñaduras provistas de unos apéndices destinados a alojarse en los extremos del núcleo de la bobina, conformando el eje de giro de la misma.The manual devices currently employed, and which have a greater relationship with that which is the subject of this invention, consist of handles provided with appendages intended to be housed at the ends of the coil core, forming the axis of rotation thereof.
Para realizar el retractilado de un producto o mercancía el operario sujeta la bobina por medio de las empuñaduras y va caminando en torno al producto a retractilar, con el fin de envolverlo con varias capas de la lámina plástica liberada de la bobina.To perform the shrinking of a product or merchandise, the operator holds the coil through the handles and walks around the product to be retracted, in order to wrap it with several layers of the plastic sheet released from the coil.
Estos dispositivos manuales resultan incómodos para el operario, especialmente cuando debe retractilar las partes inferior y superior de la carga, ya que en el primer caso debe caminar agachado y en el segundo debe subirse a una plataforma o escalera e ir cambiándola de posición para poder envolver la mercancía en cuestión.These manual devices are uncomfortable for the operator, especially when the lower and upper parts of the load must be retracted, since in the first case he must walk crouched and in the second he must climb on a platform or ladder and change his position to be able to wrap the merchandise in question.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
Para solventar los problemas mencionados se ha ideado el dispositivo para retractilar manualmente; que presenta unas particularidades constructivas orientadas a facilitar su manejo y a permitir que el operario pueda realizar el retractilado de la mercancía manteniéndose en posición erguida y sin necesidad de agacharse o de subirse a una tarima.To solve the aforementioned problems the device has been devised to retractilla manually; that presents some constructive peculiarities oriented to facilitate its handling and to allow the operator to carry out the shrinkage of the merchandise while staying in an upright position and without having to bend down or climb on a platform.
El dispositivo objeto de la invención está compuesto por una barra larga y rígida, sobre cuyos extremos se encuentran montadas coaxialmente y con posibilidad de giro libre, una empuñadura de agarre y una rueda que puede servir tanto de elemento de agarre como de elemento de apoyo sobre el suelo. Sobre la barra se encuentran montados unos medios para la retención de la bobina de material plástico en la posición de montaje. Dichos medios están compuestos por un cono fijo montado sobre el extremo de la barra portador de la rueda giratoria y por un cono desplazable a lo largo de la barra y provisto de unosThe device object of the invention is composed of a long and rigid bar, on whose ends they are mounted coaxially and with the possibility of free rotation, a grip handle and a wheel that can serve both as a gripping element as a support element on soil. Means for retaining the coil of plastic material in the mounting position are mounted on the bar. Said means are composed of a fixed cone mounted on the end of the rotating wheel carrier bar and a movable cone along the bar and provided with some
5 medios de fijación en la posición deseada.5 fixing means in the desired position.
La empuñadura giratoria presenta un diámetro igual al de la barra con el fin de permitir el montaje y desmontaje del cono desplazable y de la bobina por ese extremo del dispositivo, y la disposición de la bobina entre los dos conos 10 encargados' de fijarla sobre la barra.The rotating handle has a diameter equal to that of the bar in order to allow the assembly and disassembly of the movable cone and the coil at that end of the device, and the arrangement of the coil between the two cones 10 responsible for fixing it on the bar.
Los conos mencionados presentan en su superficie exterior unas estrías longitudinales que actúan sobre el núcleo de la bobina impidiendo el giro de la misma respecto a la barra. Í5The mentioned cones have longitudinal grooves on their outer surface that act on the core of the coil preventing its rotation with respect to the bar. Í5
De acuerdo con la invención, los medios de fijación del cono desplazable respecto a la barra están compuestos por una arandela cónica partida y por una tuerca que se fija a rosca sobre la zona posterior del cono desplazable y que presenta interiormente una superficie cónica encargada de presionar la arandela cónica contra 0 la barra, lo que provoca la inmovilización del cono desplazable.According to the invention, the means for fixing the movable cone with respect to the bar are composed of a split conical washer and a nut that is screwed onto the rear area of the movable cone and which internally has a conical surface responsible for pressing the conical washer against 0 the bar, which causes the immobilization of the movable cone.
Se ha previsto que la longitud de la barra sea superior a la de la bobina, de forma que en la posición de uso quede al descubierto, entre el cono desplazable y la empuñadura giratoria, una porción de la barra que sirve de mango. 5It is envisaged that the length of the bar is greater than that of the coil, so that in the use position it is exposed, between the movable cone and the rotating handle, a portion of the bar that serves as a handle. 5
Para conseguir el desenrollado de la lámina plástica bastará con que el operario realice el agarre del dispositivo por la empuñadura giratoria y/o por la rueda giratoria, para que la bobina gire libremente y vaya soltando la cantidad necesaria de lámina plástica a medida que avanza el operario; para realizar el 0 tensado de la lámina plástica liberada antes de ceñirla a la mercancía bastará con el que operario realice el agarre del dispositivo por la porción de barra conformante del mango y lo traccione hasta conseguir la tensión adecuada. Esta operación es posible debido a la imposibilidad de giro de la bobina respecto a la barra.To achieve the unwinding of the plastic sheet, it will be enough for the operator to hold the device by the rotating handle and / or by the rotating wheel, so that the coil rotates freely and releases the necessary amount of plastic sheet as the operator; to make the tensioning of the plastic sheet released before wrapping it to the merchandise, it will be enough for the operator to hold the device by the shaping bar portion of the handle and pull it until adequate tension is achieved. This operation is possible due to the impossibility of rotating the coil with respect to the bar.
La longitud de la barra permite que el operario aplique la lámina de plástico sobre la zona inferior de la mercancía sin necesidad de agacharse, colocando el dispositivo de retractilado de forma que la empuñadura giratoria quede en la parte superior y la rueda giratoria se mantenga apoyada sobre el suelo. Para aplicar la lámina de plástico sobre la zona superior de la mercancía el operario puede trabajar con el dispositivo de retractilado en posición invertida, es decir con la empuñadura giratoria en la parte inferior y la rueda giratoria en la parte superior.The length of the bar allows the operator to apply the plastic sheet on the lower area of the merchandise without bending down, placing the retractilating device so that the rotating handle is at the top and the rotating wheel is supported on soil. To apply the plastic sheet on the upper area of the merchandise, the operator can work with the retractilating device in an inverted position, that is, with the rotating handle at the bottom and the rotating wheel at the top.

Como se puede observar en las figuras referenciadas, el dispositivo para retractilar manualmente, objeto de esta invención comprende una barra (1), en cuyos extremos se encuentran montados coaxialmente y con posibilidad de giro libre una rueda (2), y una empuñadura (3); en la zona intermedia de la barra (1) se encuentran montados una medios para la retención de una bobina (6) de lámina plástica (61), compuestos por un cono fijo (4) y un cono desplazable (5).As can be seen in the referenced figures, the device for manually retracting, object of this invention comprises a bar (1), at whose ends a wheel (2), and a handle (3) are mounted coaxially and with the possibility of free rotation. ); in the intermediate zone of the bar (1) there are mounted a means for retaining a coil (6) of plastic sheet (61), composed of a fixed cone (4) and a movable cone (5).
El cono fijo (4) es solidario a la barra (1), mientras que el cono desplazable (5) dispone de unos medios para la fijación sobre la barra (1) en la posición deseada. Los conos (4 y 5), destinados a inmovilizar la bobina (6) sobre la barra (1) presentan en su superficie exterior unas estrías longitudinales (41 y 51) para el agarre del núcleo (62) de la bobina (6).The fixed cone (4) is integral with the bar (1), while the movable cone (5) has means for fixing on the bar (1) in the desired position. The cones (4 and 5), intended to immobilize the coil (6) on the bar (1) have longitudinal grooves (41 and 51) on its outer surface for gripping the core (62) of the coil (6).
Los medios de fijación del cono desplazable (5), están formados por una arandela cónica partida (52) y por una tuerca (53) que se monta a rosca sobre el extremo posterior del cono (5), estableciendo el apriete de la arandela cónica (52) contra la barra (1) por medio de una superficie interior cónica contrapuesta a la mencionada arandela (52).The fixing means of the movable cone (5), are formed by a split conical washer (52) and by a nut (53) that is screwed on the rear end of the cone (5), establishing the tightening of the conical washer (52) against the bar (1) by means of a conical inner surface opposed to said washer (52).
La empuñadura (3) presenta un diámetro igual al de la barra para permitir la extracción del cono desplazable (5) y el recambio de la bobina (6)The handle (3) has a diameter equal to that of the bar to allow the removal of the movable cone (5) and the replacement of the coil (6)
Como se puede observar en la figura 2, en la posición de montaje, la bobina (6) queda montada entre los conos (4 y 5), e imposibilitada de giro respecto a la barra (1). Como se muestra en la figura 3, para conseguir el desenrollado de la lámina plástica (61) de la bobina (6) bastará con sujetar el dispositivo por la empuñadura giratoria (3) o por la rueda giratoria (2) para que la bobina (6) gire libremente a medida que se desplaza el operario, liberando la cantidad de lámina plástica (61) equivalente al desplazamiento realizado.As can be seen in figure 2, in the mounting position, the coil (6) is mounted between the cones (4 and 5), and unable to rotate with respect to the bar (1). As shown in Figure 3, to achieve the unwinding of the plastic sheet (61) of the coil (6) it will be enough to hold the device by the rotating handle (3) or by the rotating wheel (2) so that the coil ( 6) Turn freely as the operator moves, releasing the amount of plastic sheet (61) equivalent to the movement made.
Tal como se muestra en la figura 4, para conseguir el tensado de la lámina (61), antes de ceñirla sobre una mercancía (7), es preciso realizar el agarre del dispositivo por la porción (1 1) de la barra (1) que queda al descubierto y que sirve de mango, traccionándolo hasta conseguir la tensión deseada de la lámina plástica (61). Esta tensión se consigue debido a la imposibilidad de giro de la bobina (6) respecto a la barra (1) y por tanto al mango (11).As shown in Figure 4, to achieve tension of the sheet (61), before wrapping it on a merchandise (7), it is necessary to hold the device by the portion (1 1) of the bar (1) which is exposed and serves as a handle, pulling it until the desired tension of the plastic sheet is achieved (61). This tension is achieved due to the impossibility of turning the coil (6) with respect to the bar (1) and therefore to the handle (11).
