Abstract

Machine to handle boxes that have several flaps to open the flaps and fix them with a seal on faces outer sides of the boxes, so that the boxes can be subsequently filled out. The machine has an octopus (200) for open the flaps and a sealer (230) to fix the flaps to the outer faces of the box. The octopus (200) has four races of work: an entry race between a position of approach and an inner position to introduce the legs (211) in the box; an opening race between an interior position and an upper position to open the box covers; a race folding between an upper position and a folding position to fold the covers over the outer faces of the box; a withdrawal stroke between a folding position and a position of approach to receive the next box.

Description

Machine to handle boxes.

Field of the Invention

The invention is included in the field of machines for handling cardboard boxes. In particular the invention refers to a machine to open the cardboard box flaps empty

Background of the invention

The applicant does not know machines that meet the Function of the machine of the invention.

Description of the invention

The machine of the invention manipulates boxes closed to extract their flaps, covers or wings and fix them with a seal on the sides of said boxes, forming an acute angle which can be 20º, so that these boxes can be subsequently filled in automatic systems.

The machine of the invention can comprise two bodies, a first body or chassis, exterior and fixed, for constitute the machine bed, and a second body or frame, interior and mobile, which supports most of the elements of job. The second body has a motor to be moved between an upper position and a lower position to work With boxes of different sizes.

The main parts of the box are:

one.

Headband of entry and clamping of the boxes;

2.

Height sensing sensors box;

3.

Octopus for the extraction of the covers;

Four.

Sealing machines for fixing tapas;

5.

Pallas of positioning of the covers.

The input and securing means of the boxes may comprise a chain device provided with drive means having between its links a plurality of stops to hold a box by the bottom of said box; said stops receive a box in an inlet curve of the chain and keep the box attached to the chain during the whole process that takes place in the machine. The chain can also comprise a plurality of first sensors to determine a position of the box to facilitate the control of height of the box and a subsequent
sealed.

The second sensors, to detect the height of a box, can be located at the entrance of the machine and can comprise second upper sensors and second sensors lower. The second sensors may be configured to determine the height of a box by intersecting the box in a beam of light between the sensors as follows:

-

The second upper sensors may be configured to maintain its beam, the upper beam, without being intersected by the edge top of the box; if the upper beam is intersected, the box current is higher than the previous box, so the second body is moved up by the engine until the beam Superior is not intersected.

-

The second lower sensors may be configured so that your beam, the lower beam, is intersected by the upper edge of the box; if the upper beam is not intersected and is not intersected the lower beam, the current box is lower than the previous box, so the second body is displaced down by the engine until the lower beam is intersected and the upper beam is not intersected

-

Yes to looking for the upper edge you reach a minimum height limit, lower limit, where the upper beam and the lower beam are not intersected, the second sensors generally a signal of no existence of a box so that the input tape is moved by the Drag means a vacuum advance.

-

Yes to looking for the upper edge you reach a maximum height limit, upper limit, where the upper beam and the upper beam are intersected, the second sensors generally a signal of size greater than the maximum permissible height level for the machine Enter stop mode.

The octopus for the extraction of the lids can understand:

a third body or frame, which has:

a plurality of legs, which can be Z-shaped, configured to open the box tops;

means of displacement to move the third body or frame in four work careers:

a first entry race between a first approach position and a second inner position to introduce the legs in the box;

A second opening stroke between a second inner position and a third upper position to open the box covers;

a third folding stroke between a third upper position and a fourth folding position to fold the covers over the faces outside of the box;

a fourth withdrawal stroke between a fourth folding position and a first approach position to receive the next box;

a fourth body or cross-shaped support that It has opening / closing means, which can be a cylinder pneumatic, to move the legs between an open position and a closed position, comprising the legs:

a first end configured to be inserted in the box;

one second end connected to the fourth body or support.

Sealing machines to fix the covers to the outer faces of the boxes can be mounted on motors linear to be displaced between an initial position and a final position that defines a squad trajectory around a edge of the box to fix two adjacent covers. The sealers they can also include a lever or lung to avoid tensions when gluing the covers on faces that form 90º and with an inclination of several degrees to prevent the covers from contacting the wall of The faces of the box. The lever or lung, which can comprise a plurality of rollers, is configured to pick up the tape in the straight area of the path to store the necessary seal to start the next hit until the curve zone passes or edge. The lever or lung can also comprise a sensor installed in the final part of the path of said lung to detect if the tape has not been pasted correctly, that is, if the lung or lever has been unloaded from tape in the curve and has loaded on the straight. The sealing machine can also comprise a cylinder that has a blade to cut the seal.

The lid positioning blades are placed next to the box when in working position to receive caps with proper inclination and prevent covers yield to the pressure of the rollers of the sealing machine. The shovel comprises a raceway between the two sides of the blade configured so that the sliding rollers of the sealer gently slide over the lid and avoid a deterioration by lid pressure. The shovels can also comprise drive means for moving the covers between a resting position and a working position, which can form each other 90º; these drive means can be pneumatic to quickly move the blades between these positions.
