Description

[0001] A LASER CUTTING MACHINE WITH SCRAP SEPARATION MECHANISM

[0002] FIELD OF INVENTION

[0003] The invention relates to a laser cutting machine having a scrap separation mechanism for cutting materials in sheet and profile form and for removing scrap parts generated during profile cutting.

[0004] BACKGROUND OF THE INVENTION

[0005] Cutting sheet metal and profiles on laser cutting machines is known in the art. In general, special profile cutting machines are used for profiles, while sheet metal sheets are cut on laser cutting machines produced for them.

[0006] Different types of cutting machines are used to ensure that said profiles and sheet metal sheets can be cut on the same machine. These cutting tables are essentially a unit configured for profile cutting, which is positioned next to the long side of the cutting table. This causes the short side of the machine to be made longer, i.e. the bridge length is extended. Due to the mentioned configuration, it is technically possible to cut both profiles and sheets with a single machine; however, the increase in the bridge length adds to the weight of the bridge. In this case, if the speed is kept constant, the cutting accuracy decreases, and if the cutting accuracy is kept constant, the speed decreases. In summary, system performance is negatively affected.

[0007] As a result, all the above-mentioned problems have made it imperative to innovate in the relevant technical field.

[0008] SUMMARY OF THE INVENTION

[0009] The present invention relates to a laser cutting machine to overcome the aforementioned disadvantages and to bring new advantages to the relevant technical field. The object of the invention is to provide a laser cutting machine in which both sheet metal and profiles can be cut and scrap parts from the cut profiles can be removed from the cutting zone.

[0010] In order to realize all the above mentioned objects and the objects which are to be deducted from the detailed description below, the present invention relates to a laser cutting machine for cutting materials in the form of sheets and profiles, comprising a main body, a bridge movable on said main body and a processing head movable on said bridge, and a profile processing table positionable within the main body during the cutting of profiles. Accordingly, a scrap separation mechanism provided on the profile processing table includes at least one comb configured to at least partially close the scrap cavity to prevent the scrap pieces that break off from the profile from falling through the scrap cavity after the length of the profile is cut, while allowing the passage of these scrap pieces. This ensures that the scrap profile pieces fall under the profile processing table, preventing possible jams, and the cut profile pieces are collected on the stacking plate on the profile processing table.

[0011] In another preferred embodiment of the subject matter invention, it comprises a profile body in which the comb is linearly displaced on the scrap separation mechanism.

[0012] In another preferred embodiment of the subject matter invention, it comprises a frame provided in the center defining a scrap cavity and linearly displaceably bearing on the profile body.

[0013] In another preferred embodiment of the subject matter invention, a transfer element is provided on an edge of the frame for transferring, by means of movement of the frame, the cut profile pieces to a stacking plate provided on the profile processing table. In another preferred embodiment of the subject matter invention, a fixed piston is connected at one end to the profile body and at the other end to the frame for moving the frame.

[0014] In another preferred embodiment of the subject matter invention, there is provided a movable piston which is connected at one end to the comb and at the other end to a piston carrier for providing movement of the comb to open and close the scrap cavity.

[0015] In another preferred embodiment of the subject matter invention, the piston carrier is linearly displaceably coupled to the profile body.

[0016] In another preferred embodiment of the subject matter invention, the comb comprises a plurality of profiles extending into the comb scrap cavity.

[0017] In another preferred embodiment of the subject matter invention, the frame comprises a plurality of comb slots in which the comb profile is at least partially disposed to guide the movement of the comb.

[0030] In this detailed description, laser cutting machine (10) is explained with references to examples without forming any restrictive effect in order to make the subject more understandable.

[0031] Referring to Figure 1 , the present invention laser cutting machine (10) comprises a processing unit (20), a profile feeding unit (30), a profile processing table (40) and at least one sheet processing table (70).

[0032] As can be seen in Figure 2, the processing unit (20) has a main body (21 ). There is a bridge (23) configured to be displaced on the said main body (21). In a possible embodiment of the invention, the main body (21 ) has two side walls (22) provided opposite each other. The bridge (23) can be displaced along the length of the main body (21 ) by bearing on the said side walls (22). A machining head (231 ) provided on the bridge (23) can also be displaced in the length direction of the bridge (23), i.e. in the width direction of the main body (21 ).

[0033] The laser cutting machine (10) of the present invention comprises at least one sheet processing table (70) and one profile processing table (40) positionable within the main body (21 ). Due to the displacement of the machining head (231) on the bridge (23) and the displacement of the bridge (23) on the main body (21), the machining head (231) is able to cut on the entire sheet processing table (70) positioned in the main body (21). On the other hand, the present invention laser cutting machine (10) is provided with a centering chuck (24) and at least one profile support member (221 ) for holding the profiles extended from the outside of the main body (21 ) into the main body (21) for profile cutting. The said centering chuck (24) and the profile support member (221) are connected to one of the side walls (22) or are provided adjacent to the side wall (22). In another preferred embodiment of the subject matter invention, multiple profile support members (221 ) are provided and the cut profile is supported at multiple points. In another preferred embodiment, the profile support member (221 ) has a carrier plate (222). The said carrier plate (222) is fixed to the side wall (22). On the carrier plate (222), there is a movable plate (223), which is vertically displaced. There is also a support part (224) on the movable plate (223). The support part (224) is connected to the carrier plate (222) in such a way that it can rotate in a vertically extending axis of rotation. The support part (224) can be provided in a form that at least partially surrounds the profile. In another preferred embodiment, the side of the support part (224) facing the profile is provided in a curved form. In a probable embodiment, the support part (224) is provided in the form of an hourglass turned on its side. The vertical movement of the movable plate (223) allows for the adjustment of the height at which the support part (224) should be positioned according to the profile diameter.

[0034] As can be seen in Figure 3, a profile feeding unit (30) is used to ensure that the profiles to be cut are fed into the body (21 ). The profile feeding unit (30) has a profile loading body (32) and a carrier chuck (33) that can move linearly on the said profile loading body (32). The said profile loading body (32) extends in the same direction as one side wall (22) of the main body (21). Thus, the carrier chuck (33) is displaced on the profile loading body (32) in such a way that it approaches and moves away from the main body (21). With the said configuration, the carrier chuck (33) and the centering chuck (24) are positioned coaxially. In this way, the profile held by the carrier chuck (33) is driven into the main body (21) and passes through the centering chuck (24). In this case, the center axis of the profile and the cutting axis of the machining head (231 ) become perpendicular to each other. The profile feeding unit (30) is provided with at least one feeding support element (34). The feeding support element (34) supports the profile from below and prevents it from stretching and sagging down. In another preferred embodiment, the feeding support elements (34) are configured to be at least partially displaced vertically. Thus, the position of the feeding support element (34) can be adjusted according to the profile diameter. A centering element (35) is provided near the end of the profile loading body (32) close to the centering chuck (24). The said centering element (35) is at least partially displaced vertically to ensure concentric alignment of the profile with the centering chuck (24).

[0035] The profile feeding mechanism (31 ) has a feeding mechanism (31 ) provided adjacent to the profile loading body (32). The said feeding mechanism (31 ) is configured to transfer the profiles positioned on it onto the feeding support elements (34) one by one. As can be seen in Figures 4 and 5, the profile processing table (40) is positioned on a chassis (41 ). When profile cutting is performed on the laser cutting machine (10), the profile processing table (40) enters the main body (21 ). The corner of the profile machining table (40) adjacent to the centering chuck (24) is defined as a cutting zone (45). In other words, when the profile machining table (40) enters the main body (21 ), the machining head (231) comes into the neighborhood of the centering chuck (24) and performs the cutting operation in the said cutting zone (45). At least one transfer element (43) is provided around a long side of the profile processing table (40). Profile cutting takes place in the neighborhood of the said transfer element (43). A stacking plate (42) extends from the area where the said cutting takes place to the other side of the profile processing table (40). In said embodiment, the transfer element (43) is configured to approach towards the stacking plate (42). Thus, the cut profile pieces are pushed by the transfer element

[0036] (43) and transferred onto the stacking plate (42). In other words, the transfer element (43) is configured to transfer the cut profiles onto a stacking plate (42).

[0037] Thanks to the said configurations, the profiles to be cut are transferred by the feeding mechanism (31 ) onto the profile support elements (221 ). Afterwards, the profile is held by the carrier chuck (33) and driven into the centering chuck (24) and reaches the main body (21 ). Meanwhile, the profile processing table (40) is positioned in the main body (21 ). The machining head (231) comes to the neighborhood of the centering chuck (24) and performs the cutting process in this region. The cut parts are then pushed by the transfer element (43) onto the stacking plate (42). When the stacking plate (42) is filled with profile pieces, the cutting stops and the profile processing table (40) is removed from the body (21 ) to take the cut profiles. In another probable embodiment there is at least one piston

[0038] (44) associated with the transmission element (43) which is the subject of the invention. With the opening and closing of the piston (44), the transfer element (43) is displaced and provides the movement of the profiles. Thanks to the said configuration, the stacked profiles are taken out of the body (21 ) together after multiple profile cutting operations. As a result, the operator no longer needs to enter the main body (21 ) to remove the cut profile pieces after the profile cutting operation. When the profiles are cut on the profile processing table (40), not only the lengths are cut. At the same time, the ends of the profiles are cut in a shaped way or holes are drilled on the profiles. This results in the need to remove the scrap pieces generated during cutting from the cutting zone (45) and the profile processing table (40).

[0039] Figures 6, 7 and 8 show representative views of the scrap separation mechanism (50). Said scrap separation mechanism (50) has a profile body (51 ). The said profile body (51 ) is essentially rectangular in shape, and the direction of the short side of the profile machining table (40) coincides with the long side of the profile body (51 ). A frame (52) is provided in the remaining part of the scrap separation mechanism (50) in the cutting zone (45). The said frame (52) is provided with a scrap cavity (53) in its center. In this way, the scrap particles generated during profile cutting in the cutting zone (45) pass through the scrap cavity (53) and fall under the profile processing table (40) (Figure 6). After the discharges and cuts are made on the profile, the length of the profile must be cut. This creates the need for the cut profile piece to remain on the profile processing table (40) without falling off. There is also a comb (55) to meet this need. Said comb (55) essentially has a multiple number of comb profiles (551) extending along the scrap cavity (53) (Figure 7). The comb (55) is configured to be able to close and open the scrap cavity (53) on demand. One of the transfer elements (43) for transferring the cut profiles onto the stacking plate (42) is also provided on the frame (52). With the displacement of the frame (52), the transfer element (43) moves and transfers the profile pieces to the stacking plate (42) (Figure 8). In another probable embodiment of the subject matter invention, the frame (52) also guides the movement of the comb (55). To achieve this, at least one comb slot (54) is provided on one edge of the frame (52), as can be seen in Figures 9a and 9b. Said comb slot (54) is provided in a plurality in accordance with the shape and number of the comb profile (551 ). Thus, the comb profiles (551 ) move within the comb slots (54).

[0040] In another probable embodiment of the invention, the scrap separation mechanism (50) is configured in the following manner to perform the said actions. The scrap separation mechanism (50) is provided with a fixed piston (58) which is fixed to the profile body (51 ) at one end. The other end of the fixed piston (58) is connected to the frame (52). In the open position of the fixed piston (58), the frame (52) is in a position where cutting operations can be performed. When the fixed piston (58) moves to the closed position, the transfer element (43) on the frame (52) transfers the cut profile to the stacking plate (42). On the other hand, there is a piston carrier (56) that is mounted to the inner wall of the profile body (51 ) and can move linearly. A movable piston (57) is connected to said piston carrier (56). The end of the movable piston (57) is also connected to the comb plate (552) of the comb (55). With the moving piston (57) in the closed position, the comb (55) is retracted and the scrap cavity (53) is left open. In this position, scrap pieces are allowed to fall down from the scrap cavity (53) by performing discharge-type cutting operations on the profile. When the movable piston (57) is in the open position, the comb (55) closes the scrap cavity (53). In this case, the profile is cut to length so that the profile piece falls on the comb profiles (551 ).

[0041] As can be seen in Figure 10, when the profile processing table (40) is positioned in the body (21) of the present invention laser cutting machine (10), at least one of the air and electricity sources needs to be connected to ensure the movement of the transfer elements (43) and the movement of the scrap separation mechanism (50). In the above-mentioned example configuration, both an electrical and air connection is required for the movement of the pistons (44), but with the use of alternative movement mechanisms, only air or only electrical connection may be required. In addition, when the profile processing table (40) is removed from the main body (21 ), a removable connection is required to prevent damage to the electrical cables and air hoses and to prevent restriction of the movement of the profile processing table (40).

[0042] In order to meet the said connection requirement, the connection configuration shown in Figure 11a-11c is provided. Said connection configuration comprises a table connection plate (61) provided on the profile processing table (40) side and a movable connection plate (66) provided on the main body (21 ) side. The said table connection plate (61) is fixed on the profile processing table (40). The movable connection plate (66) is fixed to the body (21) with a fixing plate (69). A connection piston (68) is provided between the movable connection plate (66) and the fixing plate (69). With the opening and closing movement of the said connection piston (68), the movable connection plate (66) approaches and moves away from the table connection plate (61 ). When the profile processing table (40) enters the main body (21 ), the connection piston (68) is in the closed position. When the profile processing table (40) is fully prepared for cutting, the connection piston (68) is moved to the open position and the movable connection plate (66) rests against the table connection plate (61).

[0043] A first socket (62) is provided on the table connection plate (61 ) and a second socket (67) is provided on the movable connection plate (66) for electrical passage from the main body (21 ) to the profile processing table (40). The first socket (62) and the second socket (67) are connected to each other when the connection piston (68) is in the open position and the movable connection plate (66) rests against the table connection plate (61 ). This makes it possible to transfer electric current from the body (21 ) to the profile processing table (40).

[0044] An air channel (661 ) is provided on the movable connection plate (66) for the passage of air from the main body (21 ) to the profile processing table (40). An air supply connection element (662) is provided at one end of said air channel (661 ). The said air supply connection element (662) can be fitted with air hoses from an air generator. An air inlet element (63) is provided on the table connection plate (61 ). Said air inlet element (63) is connected to the air hoses coming from the pneumatic pistons on the profile processing machine. There is also a connection end (64) and a sealing element (65) between the table connection plate (61 ) and the movable connection plate (66). Thus, when the connection piston (68) is open and the movable connection plate (66) is leaned against the table connection plate (61 ), the air connection is ensured in a leak-proof manner.

[0045] The protection scope of the present invention is set forth in the annexed claims and cannot be restricted to the illustrative disclosures given above, under the detailed description. It is because a person skilled in the relevant art can obviously produce similar embodiments in the light of the foregoing disclosures, without departing from the main principles of the present invention.
