Description

Box forming machine.

Object of the invention.

The present invention relates to a machine box former, of the type that includes: a warehouse intended to contain flat-folded boxes, means of push responsible for causing the advance of the boxes by the inside the warehouse towards an exit zone, a forming zone provided with adequate means to carry out the deployment of the boxes and means to cause the extraction of the boxes deployed from the forming area and its longitudinal advance through the inside of the machine

Background of the invention.

Currently there are different in the market box forming machines, whose purpose is to deploy the boxes from a warehouse, where they are initially folded flat, and arrange the successive sides of the boxes perpendicular to each other, taking the form of a box.

In this type of known machines the boxes, still folded, they are delivered directly from the warehouse to a forming area in which the boxes are deployed, generally using a suction cup set that immobilize one of the sides of the box and a second set of suction cups mounted on a rotating arm and which are in charge to act on the adjacent side of the box to arrange it perpendicular to the previous one and that the box adopts a form parallelepipedic

The layout of this area formed in a position facing the warehouse significantly reduces performance of the machine, since it is necessary to form the box supplied by the warehouse, extract it from said forming area and return the means from deployed to an initial position before extracting the next folded warehouse box.

Description of the invention

To solve the aforementioned problems, devised the box forming machine object of this invention, which it presents constructive characteristics oriented to provide superior performance to forming machines Conventional existing in the market.

For this, it is planned that the forming area or deployed from the boxes is distanced from the area of warehouse exit, in a direction substantially perpendicular to the direction of advance of the boxes inside said warehouse; said machine comprising a conveyor that displaces Coplanarly folded boxes, supplied by the warehouse from the warehouse exit area to the forming area, where They are deployed.

This feature allows the boxes coming from the warehouse are positioned on the conveyor and moving towards the formed area so that there are always boxes on the mentioned conveyor, prepared to enter the forming area.

On the other hand, to be distanced the formed area of the warehouse exit, the boxes can be delivered by the warehouse to the transporter without interfering with movements of those moving parts of the machine located in the formed area and responsible for unfolding the boxes.

It is envisaged that the conveyor is composed of an endless chain or belt disposed below the exit area of the warehouse, said conveyor forming a receiving element of the folded boxes supplied by the warehouse and that fall vertically, by gravity, onto said transport
tador.

This type of conveyor allows the boxes form an alignment on it and that the conveyor can keep moving without the boxes moving forward when the first of them makes contact with any element that prevents its Advance.

In this invention it is provided that the area of formed can have at least one stop responsible for limiting the advance of the folded boxes displaced by the conveyor, to as these boxes reach a certain position in which its unfolding and its collection by means of advance longitudinally responsible for extracting them from said forming area, a once deployed, and perform the dejection of those flaps or portions intended to form the base or bases of the box.

It is planned that the cashier can have several laterally aligned enclosures, disposing the exit areas of said enclosures aligned on the transporter responsible for co-moving the boxes folded towards the forming area. In this way it is possible to recharge any of the enclosures while they continue to be supplied folded boxes from any other warehouse enclosure to the conveyor.

It is also planned that the forming machine of boxes have guiding means arranged in parallel to the conveyor in order to ensure displacement coplanar of the folded boxes from the exit area of the warehouse to the forming area.

To ensure delivery of the boxes, one at a time one, on the part of the warehouse, it is foreseen that said warehouse have safety dividers in the exit area responsible for ensuring a certain distance from those boxes that are close to the exit area of the warehouse.

Description of the figures

To complement the description that is being performing and in order to facilitate the understanding of characteristics of the invention, is attached herein descriptive a set of drawings in which, with character Illustrative, the following has been represented:

- Figure 1 shows a schematic view in perspective of an embodiment of the forming machine of boxes provided with a single warehouse box dispenser folded

- Figure 2 shows a schematic view in upper floor of the machine of the previous figure in which You can see the box store and the transporter in charge of drive the boxes from the warehouse to the area of formed.

- Figure 3 shows a schematic view in perspective of a variant of the forming machine of boxes, in which the warehouse has several enclosures aligned sideways.

Preferred Embodiment of the Invention

In the exemplary embodiment shown in the Figures 1 and 2 the box forming machine has a warehouse (1) responsible for supplying the folded boxes (2), one at a time, to a conveyor (3) represented by an endless belt and responsible for driving said folded boxes (2) to an area of formed (4).

As you can see in the mentioned ones figures, the forming area (4) is distanced laterally from the exit of the warehouse (1).

The aforementioned warehouse (1) has in the area of exit of the boxes of some security dividers (5), in form star, which ensure convenient distancing of boxes to deliver, to ensure that they fall from one in one vertically and by own weight on the conveyor (3).

Folded boxes (2) are kept vertically on the conveyor (3) by the action of some lateral guides (31), having been provided in the realization of the Figure (2) that the machine has a folding stop (6) which is the responsible for slowing the advance of folded boxes (2), although the Conveyor (3) is in motion, when inside from the forming area (4) one of the mentioned boxes (2).

This forming area has, as usual, of fixed suction cups (7) responsible for immobilizing the sides of the box and folding suction cups (8) that are in charge to act on an adjacent side of the box to arrange the sides of it in perpendicular positions and perform the opening or unfolding of said box (2).

The aforementioned forming area (4) also It has conveyor belts (9) that act on the opposite sides of the box (2), once deployed, being the aforementioned tapes (9) responsible for removing the box and formed from the forming area (4).

As you can see in the example of embodiment shown in figure 3, the box store (1) can be composed of several enclosures (11) aligned laterally and with the exit areas aligned on the conveyor (3), with which ensures the continued delivery of boxes by one of the enclosures (11) for the time necessary to replace boxes (2) in any other enclosure (11).

Once nature is sufficiently described of the invention, as well as a preferred embodiment, for the appropriate purposes that the materials, form, size and arrangement of the elements described may be modified, as long as it does not involve an alteration of the essential features of the invention claimed in continuation.
