Definitions
- the present patent application for industrial invention refers to a multi-function automatic working machine for door panels.
- doors are composed of a frame fixed to the wall and a panel that rotates around one of the vertical jambs of the frame.
- the door panel is provided with hinges on the border mounted to the vertical jamb, and a lock on the opposite vertical border designed to cooperate with a metal plate provided with a suitable slot housed in the jamb of the frame.
- doors undergo a series of complex machining operations that are automatically carried out by specific working machines in which door panels are inserted in horizontal position.
- a first type of similar machines is used to install the hinges on one of the longitudinal borders of the door and the lock on the opposite longitudinal border.
- each door panel is moved forward by a conveyor belt that controls the forward movement and the stop of each door panel according to the working requirements of the tools used to mount hinges and lock.
- the presence of the conveyor belt ensures the continuous feeding of the machine, by placing several door panels one after the other on the conveyor belt.
- the door panel is loaded in a second working machine to perform the machining operations that are necessary to insert the glass pane or obtain moulding or fluting.
- the high technical-functional efficiency of the multi-function machine of the invention consists in the contemporary automatic sequence of the two machining processes that were performed either by two different work centres without coordination or in the same work centre with the manual intervention of the operator.
- a traditional machine used for horizontal operations i.e. installation of hinges and lock
- a conveyor belt with width equal at the door panel that is being machined is equipped with a conveyor belt with width equal at the door panel that is being machined.
- An innovative means was devised to support and move the door panel forward, in order to provide the removal by gravity of the machining waste and ensure the stable support of the door panel to withstand without bending or sliding effects caused by the interference of the tools used for the different operations.
- the volumes of the two operating units were optimised by suitably repositioning the tools.
- the multi-function machine of the invention comprises two different operating units (10, 100), the first lower unit (10) being equipped with the tools designed to interfere horizontally with the longitudinal borders of the door panel (A), and the second upper unit (100) being equipped with the tools designed to interfere vertically in downward direction against the upper surface of the door panel (A).
- the two units (10, 100) are designed to operate simultaneously on the same door panel, in order to reduce the time needed for the complete processing of the door panel.
- the machine of the invention comprises a bearing frame (1) formed of four uprights (2) connected two by two on top by means of suitable cross-beams (3) in order to generate two similar portal-shaped structures in opposite position.
- the portal-shaped cross-beams (3) are connected by means of a pair of long cross-pieces (4).
- the first operating unit (10) is mounted in internal position between the four uprights (2) at approximately half of their height, and the second operating unit (100) is hung to the pair of long cross-pieces (4) with the possibility of sliding in longitudinal direction.
- the first operating unit (10) is composed of a pair of longitudinal members (11,12) to support and actuate the parts designed to directly support, block and move forward the door panels that are being machined.
- the first longitudinal member (11) is permanently fixed in internal position on a pair of uprights (2) that rest on the same side of the machine of the invention (1), and the second longitudinal member (12) makes alternate parallel travels to move away or close to the fixed longitudinal member (11), thus adapting the mutual distance to the specific width of the door panel that is being machined.
- two large tubular rods (13) are perpendicularly fixed under the fixed longitudinal element (11), facing the mobile longitudinal element (12) with slightly lower length than the distance between the two uprights (2) provided on one side of the machine of the invention and the corresponding uprights (2) on the opposite side.
- Each tubular rod (13) is supported on the floor by means of suitable height-adjustable feet (13a) and supports a rectilinear guide track (14) on which a suitable slide (15) alternatively slides to support the mobile longitudinal element (12).
- the mobile longitudinal element (12) is associated with two different slides (15) that provide balanced support also during the alternate travels.
- Both tubular rods (13) support a rectilinear rack (13b) with horizontal axis on the internal side with downward teeth.
- the two racks (13b) are coupled with corresponding sprockets (16a) splined at the ends of a torsion shaft (16) longitudinally mounted under the mobile longitudinal element (12) and actuated by a gear motor that drives it into alternate travels.
- the torsion shaft (16) is rotated in a direction to get the longitudinal element (12) close to the fixed longitudinal element (11) and in the opposite direction for the return travel.
- the movement of the longitudinal element (12) in the two directions is produced by the rotation of the sprockets (16a) provided at the ends of the torsion shaft joined to it with respect to the teeth of the racks (13b) fixed in internal position on the two tubular rods (13); it being also evident that the said travels are guided by the coupling provided between the two slides (15) positioned under the mobile longitudinal element (12) and the guides (14) mounted over the two tubular rods (13).
- the longitudinal elements (11, 12) are provided with means to favour the support and continuous forward movement of the door panels loaded in the machine of the invention.
- brackets (18) in edgeways position protrude upwards from the internal side of the longitudinal elements, with horizontal bars (19) fixed on top, each of them being provided at the ends with two toothed wheels (20) that favour the closed circuit rotation of the toothed belts (11 a, 12a).
- each pair of wheels (20) one wheel is driven and one wheel is a driving wheel by means of the cooperation with a suitable gear motor (21).
- the fixed longitudinal element (11) supports a single belt (11 a) that basically covers the entire length and the mobile longitudinal element (12) supports a belt (12a) composed of two perfectly aligned segments.
- the simultaneous rotation of the two belts (11 a, 12a) allows the door panel (A) that rests on the belts (11 a, 12a) to move forward in the machine of the invention, placing the door panel (A) in the correct position for the various operations and moving the "finished" door panel out of the machine to give access to the next door panel to be machined.
- the machine of the invention is provided with additional means able to block and support the door panel (A) while the door panel is stopped in the machine to undergo the aforementioned operations.
- the door panel is permanently blocked by means of suitable clamps (22) that firmly grab the longitudinal borders of the door panel on opposite sides, being supported on the two longitudinal elements (11, 12) in an articulated way and actuated by corresponding actuators.
- the actuation of the said fixing means (22) occurs together with the actuation of the means designed to firmly support the door panel inside the machine of the invention.
- the door panel is also supported by two opposite staggered series of retractable supports (23) fixed in internal position on the longitudinal elements (11, 12), each of them basically consisting in the stem of a small jack (23a) with vertical axis fixed at the end of a small arm (24) that horizontally protrudes from the corresponding longitudinal element.
- the retractable supports (23) are basically flush with the upper section of the rotary belts (11 a, 12a) and interfere with the lower side of the door panel that is being machined in more internal position compared to the position in which the interference with the belts is produced (11 a, 12a).
- Each door panel is supported along the entire length in four (or more) points; in view of the considerable length of the support arms (24), it is evident that the retractable supports (23) are able to interfere with the door panel on opposite sides at a reduced mutual distance.
- the first operating unit (10) of the machine of the invention is equipped with the tools of known type, designed to perform machining operations in horizontal direction.
- the fixed longitudinal element (11) externally supports a high-speed rotary tool (25) designed to drill the holes for the "Anuba” type hinges on the longitudinal border of the door panel (A) and execute milling with interpolated axes for the housing that contains the assembly of hinge and fixing plate.
- An adjacent operating unit (26) with a hinge feed unit (27) is designed to screw each hinge into the corresponding hole suitably drilled by the previous tool (25).
- the mobile longitudinal element (12) externally supports a tool designed to interfere with the longitudinal border opposite to the door panel (A), which is provided with two milling units (28, 29), the first one used to obtain the slot for the lock and the second one used to obtain the housing for the fixing plate.
- the second operating unit (100) of the machine of the invention is equipped with the trolley (101) hung in transversal position to the cross-pieces (4) of the bearing frame (1) to make alternate longitudinal travels with respect to the same cross-pieces (4).
- One or more milling units (102) are supported under the trolley (101) and slide in two directions with respect to the longitudinal axis of the trolley (101), mounted in vertical position to interfere in downward direction with the door panel (A) to obtain moulding, fluting, openings (by removing large central portions of the material), and through holes for the insertion of the handle or the block of the lock.
- the retractable supports (23) that support the door panel (A) from below are able to selectively retract downwards, in order to interfere with the action of the tools that work in downward direction to perform machining operations on the door panel.
- the machine of the invention is provided with solutions for the rational disposal of the machining waste produced by the milling units (102) of the operating unit (100); this specific need has required the development of technical solutions that were not foreseen by the prior technique.
- the first technical solution was conceived to extract the wooden panels removed from the door panels machined with the machine of the invention to obtain the central opening used to insert a glass pane.
- the electronic control unit of the machine actuates the downward retraction of the supports (23).
- the lateral borders of the panel are supported by a second pair of conveyor belts (30) with longitudinal direction positioned at a slightly lower height in internal position with respect to the two belts (11 a, 12a) designed to ensure the support and forward movement of the entire door panel (A).
- the supports (23) are situated at a height lower than the height of the upper section of the two belts (30).
- the actuation of the second pair of conveyor belts (30) guarantees that the wooden panel removed from the door panel (A) is extracted from the machine of the invention according to a rectilinear direction that exactly coincides, although at a lower height, with the direction followed by the entire door panel by means of the first pair of conveyor belts (11 a, 12a).
- the conveyor belt (31) rotates in perpendicular direction with respect to the longitudinal axis of the machine, in such a way that the machining waste is ejected on the side of the machine with the fixed longitudinal element (11).
- the two tubular rods (13) for the slides (15) designed to move the mobile longitudinal element (12) are provided upstream and downstream the conveyor belt (31), that is to say in a position that does not interfere with the falling wood chips.
- the supports (23) are retracted downwards (if they have not retracted as mentioned above), the clamps (22) release the longitudinal borders of the door panel and the first pair of conveyor belts (11a, 12a) is started to take the door panel (A) to the unload area of the machine of the invention.
- the strip (17) acts as support plane for the tool of the milling unit (102) when the milling unit (102) interferes in downward direction with the door panel (A) when through holes are drilled to house the handle and the key block of the lock.
- the milling unit (102) interferes with the strip (17) in such a way to cause considerable damages; in this case the strip is replaced easily with another identical strip.
- the operating unit designed to mount hinges on the door panel (A) longitudinally slides in external position on the fixed longitudinal element (11) on which it is applied.
- the entire operating unit - including the tools (25, 26) and the hinge feeding unit (27) - is mounted on a large plate (32) in edgeways position, coupled with a pair of suitable rectilinear guides (11 b) provided in external position on the fixed longitudinal element (11); it being provided that the plate (32) is fitted to the gear motor (33) that provides movement in cooperation with a rack (33a) fixed in external position on the longitudinal element (11) in intermediate position between the two guides (11 b).
- the operating unit interferes with two or three different points on the lateral border of the door panel (A) mounted in the machine of the invention, to install the hinges.
- the fixed longitudinal element (11) can support two or three fixed operating units in external position for hinge installation.
- each operating unit only interferes with the specific section of the lateral border of the door panel (A) that stops in front of the operating unit.
