Abstract

Device for erecting a folding box blank, one section of which is folded at least approximately in the shape of a U and which has two rows of tabs (7, 8) overlapping one another. Guide rails (13-17) are provided, between which the blank is folded along four folding lines. To bend up the tabs, two spiked wheels (10, 11) are provided, the spikes of which push the tabs out of the plane of the blank. <IMAGE>

Description

DESCRIÇÃODESCRIPTION

A presente invenção refere-se a um dispositivo para a armação de um molde recortado de uma caixa do brada, do qual uma secção é dobrada pelo menos aproximadamente em forma de U e que apresenta duas fiadas de palas que se sobrepõem umas ãs outras.The present invention relates to a device for the molding of a mold cut out of a box of brada, of which a section is bent at least approximately U-shaped and which has two rows of flaps that overlap each other.

O objecto da presente invenção consiste em proporcionar um dispositivo com o qual, de uma maneira simples, pode armar-se um tal molde recortado de uma caixa dobra da e ligar o mesmo.The object of the present invention is to provide a device with which, in a simple manner, one can arm such a mold cut out of a folded box and connect it.

Segundo a presente invenção, o prob lema resolve-se se se previrem réguas de guia entre as quais o molde recortado é dobrado ao longo de quatro linhas de dobragem e se se previrem pelo menos duas rodas de espigas cujas espigas são apertadas contra as palas empurrando estas para fora do plano do molde recortado.According to the present invention, the problem is solved if guide rulers are provided between which the cut-out mold is folded along four fold lines and if at least two wheels of ears are provided whose ears are pressed against the blades by pushing these out of the cut mold plane.

• A dobragem relativamente complicada• Relatively complicated folding

N.N.

da secção em forma de U, na qual ao mesmo tempo é necessário levar as palas a sobrepor-se mutuamente, pode fazer-se com este dis positivo de maneira simples e racional, isto é, numa só operação.of the U-shaped section, in which at the same time it is necessary to bring the flaps to overlap each other, it can be done with this device in a simple and rational way, that is, in a single operation.

Segundo a presente invenção é muito conveniente se se montarem as duas rodas de espigas axialmente uma a seguir à outra e se elas apresentarem alturas diferentes das espigas adaptadas às dimensões das palas e da sua articulação.According to the present invention it is very convenient if the two spike wheels are axially mounted one after the other and if they have different heights from the spikes adapted to the dimensions of the blades and their articulation.

Nos desenhos anexos está ilustrada a presente invenção num exemplo de realização. As figuras dos de senhos representam:The accompanying drawings illustrate the present invention in an exemplary embodiment. The figures of the drawings represent:

A fig. 1, uma secção de um molde recortado de cartão provido de linhas vincadas, a fim de poder ser dobrado em forma de U;Fig. 1, a section of a mold cut out of cardboard provided with creased lines, so that it can be folded into a U-shape;

A fig. 4, uma vista de lado do dispositivo;Fig. 4, a side view of the device;

A fig. 5, uma vista parcial do dispositivo com a execu ção da dobragem em forma de U; eFig. 5, a partial view of the device with the execution of the U-shaped folding; and

A fig. 6, uma secção dobrada, pronta, no interior do dispositivo.Fig. 6, a folded section, ready, inside the device.

Na fig. 1, (1) designa um molde recortado de cartão planificado, o qual apresenta quatro linhas de dobragem (2), (3) , (4) e (5), em torno das quais se deve dobrar uma parte do molde de cartão recortado (1) em forma de U.In fig. 1, (1) means a cut out of flattened cardboard, which has four fold lines (2), (3), (4) and (5), around which a part of the cut out of the cardboard mold must be folded. (1) U-shaped.

As linhas de dobragem (3), (4) e (5) são interrompidas por linhas de corte em forma de U (6), formando-se assim as palas (7). Além disso, a linha de dobragem (2) é interrompida por linhas de corte semicirculares (8), por meio das quais são recortadas palas (9).The fold lines (3), (4) and (5) are interrupted by U-shaped cut lines (6), thus forming the flaps (7). In addition, the folding line (2) is interrupted by semicircular cut lines (8), through which flaps are cut out (9).

Nas fig. 2, 3 e 4 estão representadas duas rodas de espigas (10) e (11) que estão providas cada uma com quatro espigas. As espigas da roda maior (11) fazem pre£ são contra as palas (7) com as linhas de corte em forma de U (6), enquanto que as espigas da roda de espigas (10) um pouco mais pe quena, são dirigidas contra as palas (9) com as linhas de corteIn fig. 2, 3 and 4 there are shown two spike wheels (10) and (11) which are each provided with four spikes. The spikes of the larger wheel (11) press against the flaps (7) with the U-shaped cut lines (6), while the spikes of the spikes wheel (10) slightly smaller, are directed against the flaps (9) with the cut lines

semicirculares (8).semicircular (8).

Ά seguir a estas duas rodas de esp_i gas (10) e (11) previu-se uma régua (12) que se encaixa por baixo das palas (7) e mantêm estas na sua posição dobrada.Following these two gas wheels (10) and (11) a ruler (12) is provided that fits under the flaps (7) and keeps them in their folded position.

Nas fig. 5 e 6 está representada a estrutura restante do dispositivo, com as réguas de guia (13) a (17), com o auxílio das quais se faz a dobragem em forma de U do molde de cartão recortado ao longo das linhas de dobragem (2), (3), (4) e (5).In fig. 5 and 6 the remaining structure of the device is shown, with the guide strips (13) to (17), with the aid of which the U-shaped folding of the cut out cardboard mold along the fold lines (2) is made. ), (3), (4) and (5).

Claims

Cut out CLAIMS for a folded box, of which a section is folded at least approximately U-shaped and which has two rows of flaps that overlap each other, characterized in that guide rulers (13 to 17) are provided, among which the recessed mold is folded along four fold lines (2,3, 4,5) and because there are at least two spike wheels (10,11) whose spikes are hit against the flaps (7,9) and make get out of the cut mold plane (1).

Device according to claim 1, characterized in that the two spike wheels (10,11) are mounted axially one after the other and have a loop. different ears, adapted to the dimensions of the flaps (7,9) and their articulation.

The applicant declares that the first application for this patent was filed in the German Federal Republic on December 3, 1987, under the number <. P 37 40 920.4.
