Description

Automatic box wrapping machine plastic.

Object of the invention

The present specification refers to a application for an Invention Patent, corresponding to a automatic machine for wrapping plastic boxes, specifically of the plastic boxes used for the fruit transport, getting the machine in question the bundled with three boxes, forming a bundle that presents one of these boxes inserted or inserted vertically inside the other two boxes, placing one of these boxes face up and the other in the opposite direction, leaving the third box in the inside, the bales being lined up in a row and stacked in columns determining the obtaining of a greater number of boxes in the same space used in boxes without enfardar.

Field of the Invention

This invention has its application within the industry dedicated to the manufacture of baler machines.

Background of the invention

The applicant does not have knowledge of the present existence of an invention that present the characteristics described in this report.

Description of the invention

The automatic box wrapping machine of plastic that the invention proposes, is configured by itself as an obvious solution within your specific field of application, determining the possibility of transporting a number noticeably higher of boxes wrapped in relation to boxes without binding, which determines and results in considerable savings in The handling space.

More specifically, the automatic machine for the wrapping of plastic boxes object of the invention is constituted from a structure that presents a canvas conveyor where the attached boxes are attached to a railing located horizontally and longitudinally, placing all boxes face down or face up but always in a certain way.

The first two boxes are incorporated into position longitudinal and advance through the canvas with the collaboration of rollers up to a fixed stop, presenting an arm in the part superior implemented by some cylinders that are in extended position

Subsequently the cylinders retract, which it results in the said arm going down to its lower position, the boxes being pinched by another cylinder and rise half way through a cylinder, turning 90º with the collaboration of another cylinder to later unlock the pinch cylinder, the boxes being placed on top of a roller set

Subsequently, the arm rises to its position superior with the collaboration of some cylinders and the boxes are pushed to a table through a pusher, and then it they incorporate two boxes more than when stumbling with a stop, they turn on themselves putting themselves in transverse position, reaching through from the canvas conveyor to the roller table where the stops existing in that area stop them and leave them separated from each other, acting the pusher, who introduces them into the two boxes prepared previously, to be introduced later two more boxes that will complete the bale of six boxes.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, is attached herein descriptive, as an integral part of it, three sheets of planes in which with an illustrative and non-limiting nature, has represented the following:

Figure number 1.- Represents a view in plant of the object of the invention corresponding to a machine Automatic wrapping of plastic boxes.

Figure number 2.- Shows a profile view of the object represented in figure number 1.

Figure number 3.- Corresponds finally to a profile view of the elevator incorporated in the object of the invention.

Preferred Embodiment of the Invention

The automatic box wrapping machine of plastic that has as its mission, only and exclusively the realization of the wrapping of plastic boxes applicable to the transport of fruit and vegetable products, especially fruits, presents as main innovation the realization of the bundling of a set of boxes that in their context fulfill a mission paramount that is the transport of fruits or products fruit and vegetable inside, incorporating as a novelty the fact of significantly reducing the volume of a set of boxes to be transported empty and stacked one over the other, they have a certain volume, while with the wrapping of this invention, they manage to reduce at least 33% of the volume of the set of stacked and wrapped boxes, due to that the three boxes generate among themselves, the occupation of the set of two boxes only and exclusively, which results in savings significant both in terms of transport and in terms of intended for storage.

More specifically, the invention that is preconiza is constituted in such a way that the boxes (30) from any transportation system, they arrive at a conveyor configured as a tarp (1) established on the automatic machine for wrapping plastic boxes, standing gradually attached to a horizontal railing (2) placed longitudinally and can be incorporated both upside down as face up, always maintaining a predetermined form of placement.

The first two boxes (30) enter position longitudinal and move through the canvas (1) and with the collaboration of the rollers (7) to a fixed stop, which is It is located at the end of the rollers (7).

The invention has an arm (9) that is is now in a higher position through the cylinders (14) and (15) which are the ones that establish the position relative at certain times, which are located in fully extended position.

Said cylinders (14) and (15) retract leading the operation of lowering the arm (9) to its position bottom, getting the boxes (30) to be pinched by the cylinder (8), which rise an average travel through the cylinder (14), getting the boxes to rotate 90º through the cylinder collaboration (13).

Subsequently the cylinder (14) retracts and is unlocked through the cylinder (18) leaving the boxes located on top of the rollers (7).

Subsequently the arm (9) rises to its upper position, through the cylinders (14) and (15), the boxes they are pushed to the table (8) through a pusher (10), and to next two boxes (30) are placed that advance on the conveyor (1), which when tripping over the stop (3) turn on each other themselves, putting themselves in a transverse position, reaching through the canvas conveyor (1) to the roller table (7), where the stops (16) and (17) stop them and leave them separated from each other, being the pusher (10) who introduces them inside the two boxes (30) prepared above.

Then, two boxes are incorporated (30) that in their longitudinal position, they advance through the canvas conveyor (1) and roller table (7) to the top fixed end of rollers (7), stop marked with (3), rolling back the cylinders (14) and (15) and lowering the arm (9) to its lower position.

Then the boxes (30) using the cylinder (18), are pinched and this cylinder (18) rises to reach an average route through the operation generated by the cylinder (14), rotating the boxes (30) 50º through the cylinder (13).

Subsequently, the cylinder (14) is retracted and unlocked through the cylinder (18), leaving the boxes deposited on top of the rollers (7).

Then the arm (9) rises to the upper zone through cylinders (14) and (15), being the boxes (30) pushed to reach the table (8) through the pusher (10), forming a bale of six boxes.

The bale of six boxes (30) is clamped by the pusher (19) and the table (8) rotates 90º on its axis, depositing subsequently the assembly on top of the conveyor (11), opening the clamp (19) and the bundle of boxes moves along the conveyor (11) until reaching the stop (12), getting the table (8) return to its horizontal position.

When three bundles of boxes (30), the clamps (20) close, clamping the three bundles and they raise them to obtain a suitable height so that the three following bales pass below the previous ones, depositing the raised bales on those in the conveyor and so successively, to configure a complete pallet of boxes (30) enfardadas.
