Definitions
- the present invention relates to a squaring machine, particularly for cutting panels.
- a squaring machine is disclosed in DE 9 307 635 U, with document discloses all the features of the preamble of claim 1.
- Machines in which the management of the locator abutments for positioning the panel to be cut is controlled by automation means assisted by a numeric control system are currently proposed for squared cuts.
- Current squaring machines are constituted by a sliding frame which is supported by a telescopic arm pivoted at one end.
- a linear reference preferably an aluminum bar, is provided on the frame and is set so as to be perfectly perpendicular to the cutting line formed by the cutting blade.
- By arranging the panel to be cut on the supporting surface of the linear reference one is certain of obtaining a cut which is at right angles thereto, as demanded by manufacturing requirements.
- a sliding locator and a ruler with millimeter graduations are inserted on the linear reference, and the ruler is used as a reference for the cutting measurement.
- the linear reference is rotated with respect to the cutting line, moving it manually from its perpendicular position.
- This rotation is controlled by a fulcrum about which the aluminum bar rotates with a protractor which is applied to the sliding plane and on which the bar is positioned for the preset cutting angle.
- One method that overcomes the above-mentioned problem related to the reduction of the supporting surface consists of a bar which is rigidly coupled to the sliding surface and undergoes a rhomboidal deformation, so as to keep the supporting surface constant.
- the aim of the present invention is to eliminate the above-noted drawbacks, by providing a squaring machine which is simple in practical use for the ordinary user.
- a particular object of the present invention is to provide a machine which is highly flexible and rapid so as to meet the requirements and the demands for higher productivity.
- Another object of the present invention is to provide a machine which is simple, relatively easy to provide in practice, safe in use, effective in operation, and relatively modest in cost.
- the reference numeral 1 generally designates a squaring machine, particularly for cutting panels.
- the machine 1 comprises a footing 2 which supports, on a top 2a, a slide 2b, on which a flat carriage 3 slides which is substantially rectangular and is elongated in the direction in which it slides.
- a platform 4 which is supported by supports 5 which protrude from the footing 2.
- the platform 4 forms, on the edge 4b that lies at the front of the flat carriage 3, a slit 4a in which a cutting blade 6 is accommodated, said blade forming a cutting line 6a which is parallel to the edge 4b.
- the blade 6, as shown in Figures 2 and 3, is rotationally rigidly coupled to a horizontal secondary shaft 7a which is associated with a motor 7.
- the footing 2 rotatably supports, at a lateral lower end 2c, a telescopic arm 8 which is adapted to support a frame 9 which is articulated like a parallelogram and is coplanar to the flat carriage 3.
- the frame 9 comprises two cross-members 9a and 9b which are mutually parallel and are articulated to two stringers 9c and 9d which are also mutually parallel.
- the first cross-member 9a is rotatably connected, in the central region, to the upper end 10a of a rod 10 which is vertical and vertically adjustable and is rotatably connected, by means of its lower end 10b, to the tip of the telescopic arm 8, so as to allow horizontal support of the first cross-member 9a.
- two protrusions 12a and 12b protrude from the ends of the first cross-member 9a and rotatably support, as shown in Figures 2 and 3, a roller 12 which assists the sliding of the panels to be cut.
- the second cross-member 9b has, on the face directed toward the flat carriage 3, a sliding block 11a which can slide along a guide 11 which is associated with the other long side of the flat carriage 3.
- the first stringer 9c and the second stringer 9d are rotatably connected to the ends of the first and second cross-members 9a, 9b and are rotatably connected, in their central region, to an element 9f which acts both as a support for the panels to be cut and as a reinforcement for the frame 9.
- the first stringer 9c supports, at the tip 9g, a retention element 9h for the panels and supports, at the remaining portion, a bar 13 which is rigidly coupled thereto and internally forms a longitudinal cavity 14, as shown in Figure 6.
- the machine comprises positioning means, arranged inside the cavity 14, and the means for varying the angle of the bar 13, which are associated with the central region of the frame 9.
- the positioning means are constituted by a belt 15 which runs along the entire length of the cavity 14 so as to wrap around two pulleys 16 and 17; one of said pulleys, for example the pulley 16, is actuated by an actuator 18 which is connected thereto by means of the shaft 19.
- a locator 20 is fixed on the belt 15 and is adapted to position the panel by means of an electronic management of the actuator 18.
- the means for varying the angle of the bar 13, as shown in Figures 4 and 5, are constituted by a toothed sector 21 which is fixed on the second stringer 9d.
- the toothed sector 21 meshes with a pinion 22 which is keyed on the shaft 23 of a motor 24 which is fixed onto the element 9f.
- the motor 24 is controlled electronically and is correlated to the actuator 18 so that predefined angular variations applied to the bar 13 are matched, according to trigonometric relations, by specific linear movements of the locator 20.
- the wood panel is rested on the articulated frame 9 and placed against the bar 13, which forms a linear reference which is perpendicular to the cutting line.
- the positioning of the panel is completed by locking it with the locator 20 and the retention element 9g.
- the positioning of the panel is adjusted in a linear fashion by the locator 20 according to a predefined dimension, which is set on a computer and transmits to the actuator 18 the movements to be imparted to the positioning means.
- a predefined dimension which is set on a computer and transmits to the actuator 18 the movements to be imparted to the positioning means.
- the cutting angle is set on the computer.
- the computer transmits the processed information to the motor and to the actuator, so that a rotation of the bar 13, imparted by the motor, is automatically matched by a movement of the locator, imparted by the actuator, which leaves unchanged the distance of the locator from the cutting line.
