Scrap collection device for laser cutting machine {EQUIPMENT OF CUTTING FOR SCRAP OF LASER CUTTER}
[23] According to the present invention, when cutting the product 5 with a laser cutting machine as shown in FIG. 1 of the accompanying drawings, a cutting occurs mainly when cutting a thin plate of less than 10 mm among products having a thickness of 5 mm to 20 mm. It is related to the cutting snow collecting device for preventing the scrap 6 because the ring sensor (4) of the cutting head (3) due to the warp, such as the failure of the focusing distance can be precisely adjusted to cause the cut surface of the product and the cutting snow on the surface. .
[24] Laser cutting machine is a facility for cutting metal and stainless steel (STS) by condensing light generated from high frequency discharge type 6kw laser oscillator and cutting 5mm ~ 15mm thick product which is mainly thin film in thick plate field. In order to cut the product, the rolled blade is seated and aligned on the center of the cutting bed guide 7 with a magnet crane, and then the system is instructed to perform an automatic operation by the schedule pressure method of the operator. Starting from the right end of the head of the aligned blade to the distal end, the side cutting scraps 6 are cut first and cross cutting (CROSS CUT) is performed to cut the scraps to a certain length. (6) due to thermal stress reaction, which is a characteristic of the thin plate, the bending phenomenon occurs and the ring sensor (4) attached to the cutting head (3) does not accurately adjust the focal length. The product may be damaged or the cut scrap may come into contact with the ring sensor 4 while being rotated at the same time due to the curved shape of the bed guide, thereby causing a problem of poor cutting. In addition, since the order of product lifting, scrap lifting and next blade alignment after repeating a single sheet work, a loss of net work time is also generated.
[25] The present invention has been made in order to solve the above problems, by installing a plurality of scrap collection device with a width of about 1.5M on each of the left and right sides of the laser cutting bed guide to reduce the total amount of cutting scrap generated during scrap cutting work It operates to be collected to remove obstacles generated around the ring sensor 4 of the cutting head to prevent the cutting snow 6 'in advance. The purpose is to prevent waste.
[26] In order to achieve the above object, the present invention is connected to the lifting arm and the auxiliary arm each having a plurality of sliding devices on the upper surface through the coupling link, both the auxiliary arm guide rods to the guide groove of the inclined auxiliary arm guide on the outside Inserted and connected, the lower pin hole of the intermediate lifting arm relates to a scrap collecting device of the laser cutting machine, characterized in that is connected through the rod and the connection pin of the cylinder fixed to the ground.

[27] It will be described below in more detail based on the accompanying drawings.
[28] Fig. 2 is an overall perspective view of the apparatus installed, Fig. 3 is an overall perspective view of the grating plate installed in the apparatus, Fig. 4 is an exploded perspective view and a main sectional view of the apparatus, Fig. 5 is an operating state of the apparatus. Front view.
[29] 2 to 5, the apparatus according to the present invention is installed on the left and right sides of the cutting bed guide 7 of the laser cutting machine one by one or two sets of two, respectively, according to the size of the workplace I can regulate it.
[30] In the configuration of the apparatus 100, the auxiliary arms 13 and 13 'are connected to the left and right sides of the lifting arm 10 by fastening links 17 and 17', and the outer ends of the left and right auxiliary arms 13 and 13 '. The part is provided with guide rods 13-3 and 13'-3 and inserted into the grooves 15-1 and 15'-1 of the sub arm guides 15 and 15 ', respectively. ') Is fixed to the ground at the same inclination angle 15-2 depending on the length of the lifting arm 10 and the auxiliary arms 13 and 13' and the installation environment.
[31] In more detail, the coupling arm is formed at both ends of the lifting arm 10 at a half-width narrow end, and the connection hole provided at the inner center of the connection arm 10-1, 10'-1 has a horn shape. The connecting holes 13-1 and 13'-1 of the auxiliary arms 13 and 13 'are penetrated by the coupling links 17 and 17' in a shape and a position corresponding to 12 and 12 '. The fastening links 17 and 17 'may also be connected in communication with the apparatuses 100 in front and rear.
[32] In addition, the cylinder 16 fixed to the ground is provided with a rod hole 16-1 at the upper side and is coupled by the lower pin hole 11 and the connecting pin 11 ′ of the lower lifting arm 10 to both sides. The connected auxiliary arms 13 and 13 'are installed to be vertically operated. In addition, the sliding device 50 is provided on the upper surface of the lifting arm 10 and the left and right auxiliary arms 13 and 13 'in order to prevent a jam or a drop impact that may occur when the U-shaped scrap 6 falls. On the upper part of the sliding device 50, a metal ball 56 made of metal is mounted on the hemispherical upper surface of the lower guide 55 and is installed inside the lifting arm 10 and the auxiliary arms 13 and 13 ', and is part of the upper part. Protrudes. The lower portion of the lower guide 55 is protruded so as to be inserted into the center of the spring 53 supported on the bottom, the upper surface of the ball 56 is fastened by a bolt 54 with a perforated cover 56-1 It is supposed to be.
[33] In addition, since the apparatus 100 occupies 1.5M each on the left and right sides of the central portion 1.2M of 4.2M, which is the total width of the cutting bed guide 7, the minimum width of the thick plate product is from 1.3M to the maximum width of 4.2M. It is designed to prevent the occurrence of cutting edges that may occur when cutting all the products of
[34] When the operation of the device 100 is described, the blade is centered on the cutting bed guide (BED GUIDE) 7 by a magnetic crane to cut the product, and then the lifting arm 10 is lowered by the cylinder. As each of the left and right auxiliary arms 13 descends along the grooves of the auxiliary arm guides 15, the coupling links 17 and 17 'are bent to form a U-shape. At this time, the scrap 6 generated by the laser cutter 1 is collected by falling on the U-shaped main apparatus or the lattice board. And after the cutting operation is finished, the collected scrap (6) is transported to the magnet crane after raising the cylinder when processing. In addition, the sliding device 50 serves to prevent the hooking or impact of the scrap 6 to be dropped and collected. Therefore, regardless of the difference in blade width, the scrap 6 can be collected and lifted at a certain place at all times, so that the continuous cutting operation can be easily performed.
[35] With the above action, it is possible to collect the scrap generated at the time of cutting the product by the laser cutting machine at the lower part, and it can solve the problems such as the cutting snow caused by the deviation of the focal length of the ring sensor due to the bending of the scrap and the defect of the cutting plane. have. In addition, the cutting device can be cut immediately by aligning the next blade after finishing cutting one sheet in the lowered state, which increases the net work time and collects and lifts scrap at the same time regardless of blade width. It can be collected and lifted in large quantities and easy to work with.
