DESCRIPTION

Cutting system for cutting wood or similar panels

The present invention relates to a cutting system for cutting wood panels or the like, according to the preamble of claim 1. An example of such a cutting system is described in EP 1 510 276 A.

In the field of wood panel cutting, it is known to provide a system including a cutting machine that includes, in turn, a support structure defining a substantially horizontal support surface for at least one wood panel or the like; a cutting station; at least one feeding device for feeding the panels along the support surface and through the cutting station in a first direction; and a cutting device mounted on the cutting station so that it moves in a second direction and along a cutting plane that are perpendicular to the first direction, and to perform the cutting operation of the panels.

The cutting machine also includes a pressure device, mounted on the cutting station so that it moves perpendicular to the support surface between a panel fixing position against the support surface, and a release position.

The system also includes a power unit including, in turn, a gantry support frame that extends at least partially around, and above, the cutting machine, and a gripping device mounted on the support frame for taking the panels in sequence of a stack and release them on the support surface of the cutting machine.

The gripping device can be moved above the support surface both in said first and second directions, and in a third direction that is orthogonal to the support surface itself.

Known cutting systems for cutting wood panels or the like of the type described above have some drawbacks mainly due to the fact that said feeding unit is relatively expensive, has relatively large volumes and is not suitable for installation in plants with a relatively low height. .

The object of the present invention is to provide a cutting system for cutting wood panels or the like, which lacks the drawbacks described above and is simple to implement and reasonably cost.

According to the present invention, a cutting system for cutting wood panels or the like according to claim 1 is provided.

cross member 13 in the direction 6, together with the upper cross face 13, define a substantially horizontal support surface P for the panels 2, and one (indicated below with 14a) includes a plurality of roller bars 15 which are parallel to each other and to address 6, and the other (indicated below with 14b) includes four banks 16 that are parallel to each other and to address 6 itself.

The machine 1 also includes a cutting station 17, which is obtained in the vertical posts 8, and is equipped with a cutting device 18 including a motorized carriage 19 coupled in a known manner to the crossbar 13 to make straight movements in the direction 10 , with respect to structure 4 and under the thrust of a known drive device (not shown).

The carriage 19 supports a blade 20 and an engraver 21 that are mounted to rotate around respective longitudinal axes that are parallel to each other and to the direction 6, and to make straight movements in the direction 9 between resting positions lowered, in which the blade 20 and the engraver 21 are arranged below the surface P to be able to feed panels 2 along the surface P, and elevated operating positions, in which the blade 20 and the engraver 21 protrude through the crossbar 13 by above the surface P itself to perform the cutting of panels 2.

The blade 20 and the engraver 21 are also moved by the carriage 19 along a cutting plane 22 parallel to the direction 10, with a straight alternative movement including a forward travel, in which the engraver 21, which is placed in front of the blade 20 in the feed direction 10 of the carriage 19, engrave the panel 2 arranged on the surface P and the blade 20 performs the cutting of the panels 2, and a return path.

The device 18 cooperates with a pressure device 23 of known type, which is movable between a lowered operating position, in which the panels 2 are locked on the surface P and are cut by the device 18 parallel to the direction 10, and a resting position raised.

The machine 3 also includes a feeding device 24 for feeding the panels 2 along the surface P and through the station 17 in both directions of the direction 6.

The device 24 includes a motorized support cross member 25, which extends between the two longitudinal elements 11 in the direction 10, is slidably coupled to the two longitudinal elements 11 to make straight movements in the direction 6, with respect to the longitudinal elements 11 proper and under the thrust of a known drive device (not shown), and supports a plurality of intake elements 26 distributed along the cross member 25 in the proper direction 10 and each arranged between two respective bars 15 which They are adjacent to each other.

System 1 also includes at least one station 27 for loading panels 2 into machine 3 and / or unloading panels 2 of machine 3 itself.

In this particular case, the system 1 includes four stations 27, which are aligned with each other and with the machine 3 in the direction 10, and are divided into two pairs of stations 27 arranged on opposite sides of the machine 3 in the direction 10 proper.

Each station 27 is adapted to receive a stack 28 of panels 2, which are transferred between the station 27 and the surface P by means of at least one collection and placement assembly 29.

The assembly 29 includes a rectilinear guide 30, which extends through the stations 27 and the machine 3 in the direction 10, and is slidably engaged, in this particular case, by two movable clamping devices 31 through the stations 27 and the surface P in the direction 10 itself.

Each device 31 includes a motorized horizontal slide 32, which is slidably coupled to the guide 30, extends upward in the direction 9, and is provided with a support bar 33 slidably coupled to the slider 32 in order to perform rectilinear movements in address 9 proper.

The bar 33 includes a vertical bearing 34, which extends in direction 9, and is configured to slidably engage a feed channel 35, which is obtained through the roller bars 15 and therefore the surface P, and extends over the entire width of the surface P in the direction 10.

The bar 33 further includes a horizontal cross member 36, which extends in direction 6 and is provided with a plurality of suction elements 37 distributed along the crossbar 36 itself.

In relation to the previous explanation, it should be noted that:

each clamping device 31 is mounted below the surface P, extends through the surface P, and protrudes above the surface P in order to allow the take-up and placement assembly 29 to move the panels 2 above the surface P in the direction 10, in this particular case, between the surface P and the

stations 27; Y

the pick and place assembly 29 is configured to move below the two longitudinal elements 11.

In use, the two devices 31 are first lowered in the direction 9 to take a panel 2 of a stack 28 disposed in one of the stations 27 and then are raised in the direction 9 to move the panel 2 above the surface P The two devices 31 are then moved along the guide 30 and through the channel 35 in the direction 10, and then are lowered again in the direction 9 to release the panel 2 on the surface P itself.

Each station 27 is further provided with a limit stop device 38 adapted to allow proper placement of the corresponding stack 28 of panels 2 in the direction 6.

The device 38 is mobile between an advanced operating position, in which the device 38 is disposed within a feeding path of the devices 31 in the direction 10, and a withdrawn rest position, in which the device 38 is arranged outside of the feeding path of the devices 31 in the proper direction 10.

The assembly 29 is further associated with a panel identification device 2, in this particular case, a labeling device 39, which is supported by one of the devices 31, and includes an application unit 40 for applying the labels (not shown) ) on the panels 2 and a supply unit 41 for printing the labels (not shown) and supplying them to the unit 40 itself.

The unit 40 is slidably coupled to the crossbar 36 to perform rectilinear movements along the crossbar 36 itself in the direction 6, and the unit 41 is slidably coupled to slide 32 in order to perform rectilinear movements in the direction 9.

In using:

unit 40 takes the labels (not shown) in sequence from unit 41 combining the movements of unit 40 in direction 6 with the movements of unit 41 in direction 9;

unit 40 can be moved over panels 2 to label the panels 2 themselves; Y

the unit 41 is moved below the surface P to allow the movement of the clamping device 31 through the surface P itself in the direction 10.

According to some variants (not shown):

the pick and place assembly 29 is further provided with a milling and / or drilling unit; each station 27 receives only one panel 2 at a time;

the blade 20 and the engraver 21 have been removed and replaced by a milling cutter; and the unit 40 is mobile, with respect to the crossbar 36, in the direction 9.

System 1 has some advantages due mainly to the fact that:

the pick and place assemblies 29 have relatively small dimensions, are relatively compact, and therefore are of relatively reasonable cost;

the pick and place assemblies 29 can be installed in systems 1 already available in the market by simply modifying the support device 14a in order to make the channel 35; Y

the operation of labeling panels 2 will be carried out at a predetermined distance from the cutting station 17 and, therefore, from the machine zone 3 characterized by the presence of processed chips, scrapes and dust.
