Abstract
Description
Technical Field
[0001] This invention relates to a machine for drilling panels (such as wooden panels or similar materials), the machine comprising a plurality of reference elements respectively arranged in a first processing area and a second processing area. These reference elements are capable of aligning and positioning the panel by intercepting its movement upon contact, thereby facilitating precise tilt drilling on one or more surfaces of the panel positioned to correspond to the machine's tilting drilling device. Background Technology
[0002] Machines for drilling panels are well known and include a workbench on which panels made of wood, wood fiber, plastic, fiberglass or similar materials can be placed.
[0003] These machines include a base and a worktable mounted on the base.
[0004] The worktable includes a first machining zone and a second machining zone for drilling the panel when it is placed in one of the zones. Each machining zone contains a reference element to properly position the panel for drilling within the corresponding machining zone.
[0005] When the panel is positioned in the first machining area, the left side surface of the panel is drilled using a first machining head mounted on a frame movable relative to the worktable.
[0006] The first machining head is equipped with drilling devices to drill the left side surface of the panel. These drilling devices are capable of orthogonal drilling relative to the left side surface of the panel.
[0007] After drilling the left lateral face, the panel is moved from the first processing area to the second processing area via a propulsion device (such as a panel conveyor belt).
[0008] When the panel is in the second machining area, the right side surface of the panel is drilled using a second machining head mounted on a frame that is movable relative to the worktable.
[0009] In this case, drilling is performed perpendicular to the right side face of the panel.
[0010] However, among known panel drilling machines, the types of precise operations or operations with tolerances that can be performed on the panel surface are limited.
[0011] Therefore, it is hoped that this limitation can be overcome by expanding the range of precise operations that can be performed on the panel surface. Utility Model Content

[0025] In the various figures, similar parts are indicated by the same reference numerals.
[0026] refer to Figures 1-3 Machine 1 is shown as being used for drilling panel P, such as a wooden panel, plastic panel, fiberglass panel, glass panel or similar panel.
[0027] like Figure 5As shown, each panel P includes an upper surface Fs, a lower surface Fi that can be fixed to the machine's worktable 1 opposite to the upper surface Fs, and a plurality of side surfaces, including a front surface Fa, a rear surface Fb opposite to Fa, a left side surface Fls, and a right side surface Fld.
[0028] The machine 1 is capable of drilling one or more surfaces of panel P in order to insert pins or nuts required for assembling panel P, for example, to build a furniture frame.
[0029] Machine 1 includes a base 10 and a worktable 20 mounted on the base 10, on which the panel P to be drilled is placed.
[0030] The worktable 20 includes a first machining area 21 and a second machining area 22 for drilling the panel P.
[0031] The second processing area 22 is located at a predetermined distance from the first processing area 21.
[0032] Machine 1 also includes a panel propulsion device 70 for panel P, which is configured to move panel P between a first processing area 21 and a second processing area 22, and vice versa.
[0033] The propulsion device 70 enables the panel P to be moved so as to drill corresponding portions of the two opposing lateral surfaces Fls, Fld and / or the upper surface Fs of the panel P without requiring the panel P to rotate on the worktable 20.
[0034] The propulsion device 70 may include a belt, chain, or transmission system for dragging the panel P.
[0035] The propulsion device 70 may include clamping or gripping elements configured to engage with at least two opposing lateral surfaces Fls, Fld of the panel P or the lower surface Fi of the panel P, thereby allowing movement to a desired position.
[0036] The workbench 20 may also include a first loading / unloading area 23 for panel P adjacent to the first processing area 21 and a second loading / unloading area 24 for panel P adjacent to the second processing area 22.
[0037] The propulsion device 70 enables the panel P to be moved to the corresponding loading / unloading areas 23, 24, so as to remove the drilled panel P or replace the drilled panel P with a new panel P to be drilled.
[0038] The first processing area 21 and the second processing area 22 are located between the first loading / unloading area 23 and the second loading / unloading area 24 of panel P.
[0039] Figure 2 An XY plan view of the worktable 20 of machine 1 for drilling panel P is shown.
[0040] like Figure 2 As shown, each processing zone 21, 22 includes reference elements 211, 221, 231 for correctly positioning the panel P to be drilled within the corresponding processing zone 21, 22.
[0041] Specifically, the first processing area 21 includes a first set of reference elements 211, 231 to stop the panel P when the reference elements 211, 231 are in contact with both the third lateral surface Fls and the second lateral surface Fa.
[0042] The first set of reference elements 211, 231 includes at least one first reference element 211 positioned along a first transverse axis Y1 parallel to the worktable 20 and a second reference element 231 arranged along a longitudinal axis X1 parallel to the worktable 20 and orthogonal to the first transverse axis Y1.
[0043] The second processing area 22 includes a second set of reference elements 221, 231, to stop the panel P when the reference elements 221, 231 are in contact with both the first lateral surface Fld and the second lateral surface Fa.
[0044] The second set of reference elements 221, 231 includes at least one third reference element 221 positioned along a second transverse axis Y2 parallel to the worktable 20 and a second reference element 231 arranged along a longitudinal axis X1 orthogonal to the second transverse axis Y2.
[0045] The first reference element 211 and the third reference element 221 can be arranged in a mirror image relative to the worktable 20.
[0046] The first reference element 211 and / or the third reference element 221 may be retractable movable elements configured to present a retracted position below the worktable 20 (when they are positioned below the worktable 20) and an extended position above the worktable 20, in which they rise to a height sufficient to contact the panel P.
[0047] In this way, when panel P is moved by pusher device 70 into first processing area 21 or second processing area 22, the corresponding first reference element 211 or third reference element 221 is raised to a level that interferes with the movement of panel P, thereby acting as a stop for panel P itself.
[0048] Therefore, during the processing, panel P is constrained to prevent undesirable movement relative to table 20, particularly corresponding to the respective processing areas 21, 22.
[0049] Machine 1 may include a control logic unit configured to generate a signal in response to an indication that panel P is positioned in the first processing area 21, causing at least one first reference element 211 to extend; or
[0050] A signal is generated in response to an indication that panel P is positioned in the second processing area 22, causing at least one third reference element 221 to extend.
[0051] The signal indicating that the indicator panel P is positioned in the first processing area 21 or the second processing area 22 can be generated by a sensor device (such as an optical positioning sensor (not shown in the figure)) that can detect the position of the panel P relative to the worktable 20.
[0052] Alternatively, the signal indicating that the indicator panel P is positioned in the first processing area 21 or the second processing area 22 can be generated in response to operator commands, such as by means of electronic devices or operating terminals.
[0053] Unlike the first reference element 211 and / or the third reference element 221, the second reference element 231 can be fixedly positioned along the entire length of the worktable 20.
[0054] For example, the second reference element 231 can be positioned along one side of the worktable 20, extending longitudinally over its entire length, and can also be used as a sliding guide for the panel P.
[0055] Contact with the second reference element 231 can be ensured by pushing the panel P against at least one of the pushing elements 81, 82 of the second reference element 231.
[0056] Specifically, the pushing elements 81 and 82 are configured to push the panel P into contact with the first set of reference elements 211 and 231 when the panel P is located in the first processing area 21 and / or to push the panel P into contact with the second set of reference elements 221 and 231 when the panel P is located in the second processing area 22.
[0057] Furthermore, in this case, the actuation of the movement of the actuating elements 81 and 82 can be assigned to the control logic unit, which generates an actuation signal based on the position of the panel P relative to the worktable 20 detected by the positioning sensor device.
[0058] The pushing elements 81 and 82 ensure the correct positioning of panel P relative to the second reference element 231.
[0059] Refer again Figures 1-3The panel drilling machine 1 also includes drilling devices 40 and 50 for drilling at least one surface of the panel P positioned corresponding to the drilling devices 40 and 50, such as the left lateral surface Fls, the right lateral surface Fld and / or the upper surface Fs located near the left lateral surface Fls or the right lateral surface Fld.
[0060] These drilling devices 40, 50 are positioned to correspond to the first machining area 21 and / or the second machining area 22, and include a motorized component and at least one spindle 401, 501, which is designed to hold a corresponding drill bit 4011, 5011 for drilling the panel P when the spindle 401, 501 is actuated by the driving component.
[0061] The drilling devices 40 and 50 may include a first drilling device 40 positioned corresponding to the first machining area 21, for drilling at least a portion of the left lateral surface Fls and / or the upper surface Fs located near the third lateral surface Fls when the third lateral surface Fls and the second lateral surfaces Fa and Fb are in contact with the first set of reference elements 211 and 231.
[0062] The drilling devices 40 and 50 may include a second drilling device 50 positioned near the second processing area 22 for drilling at least a portion of the first lateral surface Fld and / or the upper surface Fs near the right lateral surface Fld when the first lateral surface Fld and the second lateral surfaces Fa and Fb are in contact with the second set of reference elements 221 and 231.
[0063] Drilling devices 40 and 50 can be installed on the corresponding machining heads 641 and 651 of machine 1.
[0064] When the panel P to be drilled is placed in the first machining area 21, drilling of the left lateral surface Fls or the upper surface Fs located near the left lateral surface Fls is performed by the first machining head 641 mounted on the table 64 movable relative to the worktable 20.
[0065] Conversely, when the panel P to be drilled is placed in the second machining area 22, drilling of the right lateral surface Fld of the panel P or the upper surface Fs located near the right lateral surface Fld is performed by the second machining head 651 mounted on the table 65 movable relative to the worktable 20.
[0066] Specifically, refer to Figure 3 The image shows a perspective view of machine 1 used for drilling panel P.
[0067] Machine 1 may include multiple movable stands 64, 65 that can move along the X-axis, and processing heads 641, 651 can slide on the multiple movable stands.
[0068] The machining heads 641 and 651 can be processed along a path parallel to... Figure 3 The Y-axis of the Cartesian coordinate system XYZ shown is slid in the direction of the axis.
[0069] Figure 4 Provided Figure 3 The detailed perspective view of the machine 1 shown shows a first set of spindles 401, each of which is positioned at an angle α relative to the portion of the third lateral surface Fls and / or the upper surface Fs located near the third lateral surface Fls.
[0070] The spindle 401 can perform inclined drilling at an angle α relative to the third lateral surface Fls of the panel P or at an angle α relative to the portion of the upper surface Fs located near the third lateral surface Fls.
[0071] The second set of spindles 501 in Figure 4 While not visible in the center, the second set of spindles 501 are similarly positioned at an angle α relative to the portion of the first lateral surface Fld and / or the upper surface Fs of the panel P located near the first lateral surface Fld, for example, as shown in the image. Figure 2 As shown.
[0072] The spindle 501 allows for inclined drilling at an angle α relative to the first lateral surface Fld of the panel P or at an angle α relative to the portion of the upper surface Fs located near the first lateral surface Fld.
[0073] The tilt angle α can range from 30° to 60°, and is preferably approximately 45°.
[0074] The angled hole is designed to facilitate the insertion of the pin.
[0075] This provides the advantage of enabling more durable panel-to-panel connections for furniture frame components, while also simplifying and improving the safety of the assembly process.
[0076] By using the first set of reference elements 211, 231 and the second set of reference elements 221, 231, the panel P can be correctly referenced on the corresponding machining areas 21, 22, and the corresponding lateral surfaces Fls, Fld can be aligned for inclined drilling with the aid of the corresponding spindles 401, 501 at an angle α relative to the surfaces Fls, Fld, Fs to be drilled.
[0077] Such alignment of panel P with the corresponding reference elements 211, 221, 231 reduces drilling errors. This differs from vertical / orthogonal drilling, in which the difference between the actual size of panel P and the expected / estimated size of panel P results in tolerable depth variations. In the case of inclined drilling, such differences cause displacement of the actual drill point relative to the desired drill point on panel P, resulting in unacceptable errors in forming the correct furniture frame.
[0078] At least one spindle 401, 501 can rotate about the axis of rotation C (e.g., the axis perpendicular to the worktable 20) to facilitate drilling at different angles, thereby adapting to the hole sequence of different panels or different machining tasks.
[0079] Spindle 401 and 501 can be actuated independently and are arranged perpendicular to the worktable 20.
[0080] Mandrels 401 and 501 may include at least two mandrels, and drill bits 4011 and 5011 are oriented in opposite directions along an axis X parallel to the worktable 20.
[0081] Reference Figures 6-9 A second embodiment of a machine 1' for drilling panel P is shown, which is similar to... Figures 1-4 The difference of the first machine 1 described in the text is that it does not include at least one driving element.
[0082] In this second embodiment, the correct positioning of panel P relative to the second reference element 231 is ensured by a propulsion device 70, which moves panel P from the first processing area 21 to the second processing area 22 and vice versa, while keeping panel P aligned with the second reference element 231.
[0083] The first advantage of this innovation is that the panel P can be correctly referenced within the corresponding processing areas 21, 22, thereby facilitating accurate tilt drilling of the corresponding portions of the panel P located near or corresponding to the corresponding side surfaces Fls, Fld and / or the upper surface Fs of the opposite side surfaces Fls, Fld by means of the tilt drilling devices 40, 50 of the machines 1, 1'.
[0084] The second advantage of this innovation is that when panel P is positioned in the corresponding processing areas 21 and 22 of machines 1 and 1', the movement of the panel can be intercepted, thereby facilitating accurate tilting drilling of the corresponding portions of the opposite lateral surfaces Fls and Fld and / or the upper surface Fs of panel P located near or corresponding to the corresponding lateral surfaces Fls and Fld.
[0085] The third advantage of this innovation is that it can expand the range of accurate operation, which can be performed by means of machines 1, 1' on the lateral surfaces Fls, Fld of panel P and / or on the upper surface Fs in the corresponding portion located near or corresponding to the respective lateral surfaces Fls, Fld.
[0086] The present invention has been described by way of illustration rather than limitation according to preferred embodiments thereof. It should be understood that changes and / or modifications may be made by those skilled in the art without departing from the scope of protection defined by the appended claims.
