Description

[0002] Laser coil cutting machines occupy a large market in today's thin plate cutting field. They have the characteristics of fast cutting speed, high quality, and high material utilization. However, material recovery after cutting parts is relatively troublesome and labor-intensive.

[0003] The prior art discloses a CNC laser cutting machine tool, including a machine body, a feeding mechanism, a laser cutting head, a conveying mechanism and a tail material recovery mechanism. The feeding mechanism reels in a plate and conveys the plate to the conveying mechanism, which pulls the plate and continuously feeds the material. At the same time, the laser cutting head moves on the machine body to complete the cutting, and the tail materials (i.e., scraps) generated during the cutting can be conveyed to an arc recovery end via the conveying mechanism, and fall downward to the recovery mechanism for recovery under the guidance of the arc surface of the arc recovery end. However, in this scheme, when the tail materials are recovered, the synchronous transportation of the cut plates causes interference, or the plates need to be reeled in, resulting in discontinuous operation.

[0035] Embodiment 1

[0036] A tail material recovery device for a laser coil cutting machine, such as Figures 1 to 4 As shown, it includes a sheet material separation mechanism 1, a finished product picking platform 2 and a tailing material recovery mechanism 3. The tailing material recovery mechanism 3 is located below the finished product picking platform 2. The sheet material separation mechanism 1 is located at one end of the finished product picking platform 2. The sheet material separation mechanism 1 is used to separate the finished product 7 from the tailing material 8. The finished product picking platform 2 is used to place the separated finished product 7. The tailing material recovery mechanism 3 is used to recover the separated tailing material 8.

[0037] The tail material recovery device of the above-mentioned laser coil cutting machine can be used in conjunction with the laser coil cutting machine 6, and the finished product picking platform 2 is equipped with a plate separation mechanism 1 at one end which is connected to the cutting area 61 of the laser coil cutting machine 6. After the coil is cut in the cutting area 61, it continues to move to the plate separation mechanism 1 under the action of the laser coil cutting machine 6 to separate the cut finished product 7 from the tail material 8. The cut finished product 7 is sent to the finished product picking platform 2 through the plate separation mechanism 1 and can be taken away. The cut tail material 8 can be towed to the tail material recovery mechanism 3 after passing through the plate separation mechanism 1 and rolled up for recovery under the action of the tail material recovery mechanism 3. The finished product 7 and the tail material 8 are completely separated without interfering with each other, thereby improving operation continuity and work efficiency.

[0038] like Figures 1 to 4As shown, the sheet material separation mechanism 1 includes a first roller 11, a second roller 12, a third roller 13 and a first frame 14 and a second frame 15 arranged opposite to each other. The two ends of the first roller 11, the two ends of the second roller 12 and the two ends of the third roller 13 are rotatably connected to the first frame 14 and the second frame 15 respectively. The second roller 12 is located between the first roller 11 and the third roller 13. The finished product 7 passes through the gap between the first roller 11 and the second roller 12 to the finished product picking platform 2, and the tail material 8 passes through the gap between the second roller 12 and the third roller 13 to the tail material recovery mechanism 3. During implementation, the coil moves toward the tail material recovery mechanism 3 under the action of the laser coil cutting machine 6, and the finished product 7 can continue to move forward under the driving action of the laser coil cutting machine 6 and pass through the gap between the first roller 11 and the second roller 12 and then enter the finished product picking platform 2. Since the coil softens during laser cutting, the tail material 8 can be manually pulled through the gap between the second roller 12 and the third roller 13 to the tail material recovery mechanism 3, and the subsequent tail material 8 continues to move under the action of the tail material recovery mechanism 3, so as to realize the separation of the finished product 7 and the tail material 8 and avoid mutual interference between the finished product 7 and the tail material 8.

[0039] like Figures 1 to 4 As shown, the finished product picking platform 2 includes a driving member, a belt 21, a first roller 22 and a second roller 23 connected by the belt 21, the output end of the driving member is connected to the first roller 22, and both ends of the first roller 22 and the second roller 23 are respectively rotatably connected to the first frame 14 and the second frame 15. During implementation, the driving member drives the first roller 22 to rotate, drives the belt 21, and then transports the finished product 7 separated by the sheet separation mechanism 1.

[0040] like Figure 1 , Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the tail material recovery mechanism 3 includes a base 31, a motor 32, a synchronous belt transmission mechanism 33, a transmission shaft 34 and a recovery roller 36. The motor 32 is installed on the base 31. The output end of the motor 32 is connected to the input end of the synchronous belt transmission mechanism 33. The output end of the synchronous belt transmission mechanism 33 is connected to the recovery roller 36 through the transmission shaft 34. The separated tail material 8 is wound around the recovery roller 36. During implementation, the coiled material softens during laser cutting. After the cutting is completed, the tail material 8 is passed through the gap between the second roller 12 and the third roller 13 and then pulled to the winding recovery roller 36. The motor 32 drives the transmission shaft 34 to rotate through the synchronous belt transmission mechanism 33, and then drives the recovery roller 36 to rotate, so that the tail material 8 is rolled up and recovered. The recovered tail material 8 is cylindrical, which is convenient for storage and transportation.

[0041] like Figure 7 , Figure 8As shown, the transmission shaft 34 is equipped with a claw 35, and the transmission shaft 34 is detachably connected to the recovery roller 36 through the claw 35. Specifically, the claw 35 can be a pneumatic claw. After the coil cutting is completed, the finished product 7 is separated from the tail material 8 by the sheet separation mechanism 1, and the motor 32 drives the recovery roller 36 to rotate and roll up the tail material 8 of the current coil. When the tail material 8 of the current coil is recovered, the pneumatic claw 35 releases the clamping of the recovery roller 36, and the recovery roller 36 can be taken away, and a new recovery roller 36 is replaced to continue to be used for the recovery of the tail material 8 of the next coil.

[0042] like Figures 1 to 3 , Figure 5 and Figure 6 As shown, the transfer mechanism 4 is also included, and the transfer mechanism 4 includes a track seat 41, a transfer vehicle 42 and a receiving tray 43. The receiving tray 43 is located at the top of the transfer vehicle 42 and the receiving tray 43 is located below the recycling roller 36. The transfer vehicle 42 is slidably connected to the track seat 41. Specifically, the receiving tray 43 includes a base 431 and blocks 432 located on both sides of the top of the base 431, and the two blocks 432 have inclined surfaces inclined toward the middle of the base 431. When the recycling roller 36 completes the recycling of the tail material 8 of the current coil, the claw 35 releases the clamping of the recycling roller 36, and the recycling roller 36 with the tail material 8 wound around it automatically falls to the middle of the base 431, and the inclined surfaces of the two blocks 432 limit and block the recycling roller 36 to prevent the recycling roller 36 from rolling down.

[0043] The transfer vehicle 42 is equipped with a lifting mechanism 44, and the output end of the lifting mechanism 44 is connected to the receiving tray 43. Figure 6 As shown, a plurality of guide rods 45 are provided at the bottom of the receiving tray 43, and the plurality of guide rods 45 are passed through the transfer vehicle 42. When the lifting mechanism 44 drives the receiving tray 43 to rise and fall, the plurality of guide rods 45 guide the receiving tray 43. The lengths of the tail materials 8 generated by different coils may be different, resulting in different radial dimensions of the cylindrical tail materials 8 when the final recovery roller 36 recovers the tail materials 8. The height position of the receiving tray 43 can be adjusted by the lifting mechanism 44 to adapt to the recovery of the tail materials 8 of different coils.

[0044] Embodiment 2

[0045] This embodiment is similar to the first embodiment, except that Figure 1 , Figure 2 , Figure 4 , Figure 7 and Figure 8As shown, the adjusting mechanism 5 is also included, and the adjusting mechanism 5 is located between the sheet material separation mechanism 1 and the tail material recovery mechanism 3, and the adjusting mechanism 5 is used to limit the position of the separated tail material 8. During implementation, when the recovery roller 36 rotates to roll up the tail material 8, the tail material 8 is easily out of position due to the softening of the tail material 8, and finally winds off the two ends of the recovery roller 36, affecting the recovery of the tail material 8. The adjusting mechanism 5 can be adjusted according to the size of the coiled material to limit the position of the tail material 8, so as to ensure that the tail material 8 can normally wind around the recovery roller 36.

[0046] like Figure 7 , Figure 8 As shown, the adjustment mechanism 5 includes a base 51, a handle 52, a rotating rod 53, a first limiting assembly 54 and a second limiting assembly 55. The handle 52 is connected to one end of the rotating rod 53. The rotating rod 53 is rotatably connected to the top of the base 51. The two ends of the rotating rod 53 are respectively provided with a first screw segment 531 and a second screw segment 532 with opposite spiral directions. The first limiting assembly 54 and the second limiting assembly 55 are respectively connected to the first screw segment 531 and the second screw segment 532, and the first limiting assembly 54 and the second limiting assembly 55 are respectively in contact with the two sides of the tail material 8. Specifically, the adjustment mechanism 5 also includes a guide rod 56. The two ends of the guide rod 56 are fixed to the base 51. Fig. 9 As shown, the first limiting assembly 54 includes a first slider 541, a first extension arm 542, a first disc 543 and a first support rod 544. The first slider 541 is connected to the first screw segment 531, and the first slider 541 is slidably connected to the guide rod 56. One end of the first extension arm 542 is connected to the first slider 541, and the first disc 543 is arranged at the other end of the first extension arm 542, and the first disc 543 is arranged vertically on the base 51, and the first support rod 544 is fixedly connected to the middle of the first disc 543; Fig.10As shown, the second limiting assembly 55 includes a second slider 551, a second extension arm 552, a second disc 553 and a second support rod 554. The second slider 551 is connected to the second screw segment 532, and the second slider 551 is slidably connected to the guide rod 56. One end of the second extension arm 552 is connected to the second slider 551. The second disc 553 is arranged at the other end of the second extension arm 552, and the second disc 553 is arranged vertically on the base 51. The second support rod 554 is fixedly connected to the middle part of the second disc 553, and the first support rod 544 and the second support rod 554 are respectively located between the first disc 543 and the second support rod 554. On the opposite side of the two discs 553, during implementation, according to the size of the coiled material, the handle 52 is rotated to rotate the rotating rod 53, thereby causing the first slider 541 and the second slider 551 to move towards or away from each other. When the tail material 8 is recovered, the tail material 8 passes through the gap between the second roller 12 and the third roller 13, and the first support rod 544 and the second support rod 554 are used to support the tail material 8 on both sides. At the same time, the first disc 543 and the second disc 553 are used to limit the tail material 8 to prevent the tail material 8 from moving outward and out of position, thereby ensuring that the tail material 8 can be correctly wound around the recovery roller 36 without falling off.

[0047] Embodiment 3

[0048] A tail material recovery method for a laser coil cutting machine is applied to the tail material recovery device of the laser coil cutting machine in the first or second embodiment, comprising the following steps:

[0049] S1: For the cut coil, the sheet separation mechanism 1 is used to separate the finished product 7 from the tailing 8;

[0050] S2: The separated finished product 7 is sent to the finished product picking platform 2, and the separated tailings 8 are pulled to the tailings recovery mechanism 3 for recovery.

[0051] In the above-mentioned method for recycling tailings of the laser coil cutting machine, after the coil is cut in the cutting area 61 of the laser coil cutting machine 6, the cut finished product 7 is separated from the tailings 8 by the plate separation mechanism 1. The cut finished product 7 is sent to the finished product picking platform 2 by the plate separation mechanism 1 and can be taken away. The cut tailings 8 can be pulled to the tailings recycling mechanism 3 after passing through the plate separation mechanism 1 and rolled up for recycling under the action of the tailings recycling mechanism 3. The finished product 7 and the tailings 8 are completely separated without interfering with each other, thereby improving operation continuity and work efficiency.

[0052] In step S1 , the specific process of separating the finished product 7 from the tailings 8 is: passing the finished product 7 through the gap between the first roller 11 and the second roller 12 , while guiding the tailings 8 to pass through the gap between the second roller 12 and the third roller 13 .

[0053] In step S2, the movement range of the tail material 8 can be limited by the adjustment mechanism 5 to prevent the tail material 8 from moving outward and out of position, thereby ensuring that the tail material 8 can be correctly wound around the recovery roller 36 without being disengaged.

[0054] In step S2, after the tail material 8 of the current coil is recovered, the recovery roller 36 wrapped with the tail material 8 can be removed, and the recovery roller 36 can be transported away by the transfer mechanism 4, and replaced with a new recovery roller 36 for recovering the tail material 8 of the next coil.

[0055] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
